2025 ACC/AHA/ Guideline for the Management of Patients With Acute Coronary Syndromes

3 Mar, 2025 | 18:02h | UTC

Introduction:

This summary highlights the key points from the 2025 ACC/AHA/ACEP/NAEMSP/SCAI Clinical Practice Guideline on the management of acute coronary syndromes (ACS). It covers both ST-segment elevation myocardial infarction (STEMI) and non–ST-segment elevation ACS (NSTE-ACS), emphasizing timely diagnosis, reperfusion strategies, risk stratification, and secondary prevention. The primary aim is to help clinicians provide evidence-based and up-to-date care to reduce mortality, complications, and long-term adverse outcomes in patients with ACS.

Key Recommendations:

• Early and Accurate Diagnosis

  • Obtain and interpret a 12-lead ECG within 10 minutes of first medical contact in suspected ACS.
  • Use high-sensitivity troponin testing to accelerate ruling in/out myocardial infarction.

• Reperfusion in STEMI

  • Primary percutaneous coronary intervention (PPCI) is the preferred strategy if it can be performed within 90 minutes (or 120 minutes for transfers).
  • In patients with anticipated long delays, fibrinolytic therapy is recommended if there are no contraindications and the patient presents within 12 hours of symptom onset.

• Routine Invasive vs. Selective Invasive Strategy in NSTE-ACS

  • Patients at intermediate or high ischemic risk benefit from an invasive strategy during hospitalization.
  • Low-risk patients may undergo a selective invasive approach, incorporating noninvasive testing to guide the need for angiography.

• Multivessel Coronary Artery Disease Management

  • For hemodynamically stable STEMI patients with nonculprit lesions, complete revascularization (either during the index procedure or staged) lowers future events.
  • In NSTE-ACS, complete revascularization decisions (PCI vs. CABG) depend on anatomical complexity and comorbidities.

• Antithrombotic Therapy

  • Initiate dual antiplatelet therapy (DAPT) with aspirin plus a P2Y12 inhibitor (ticagrelor or prasugrel preferred over clopidogrel for most) for at least 12 months in patients without high bleeding risk.
  • To reduce bleeding risk in patients with ACS several strategies are available:
    a) in patients at risk for gastrointestinal bleeding, a proton pump inhibitor is recommended;
    b) in patients who have tolerated dual antiplatelet therapy with ticagrelor, transition to ticagrelor monotherapy is recommended ≥1 month after PCI;
    c) in patients who require long-term anticoagulation, aspirin discontinuation is recommended 1 to 4 weeks after PCI with continued use of a P2Y12 inhibitor (preferably clopidogrel).

• Parenteral Anticoagulation

  • All ACS patients should receive an anticoagulant (e.g., unfractionated heparin, low-molecular-weight heparin, bivalirudin) depending on the clinical scenario and planned strategy (PCI, CABG, or medical management).

• Lipid Management

  • High-intensity statin therapy is recommended in all ACS patients.
  • Add a nonstatin agent (e.g., ezetimibe, PCSK9 inhibitor) if LDL cholesterol remains ≥70 mg/dL on maximally tolerated statin.

• Heart Failure and Cardiogenic Shock

  • In acute MI with cardiogenic shock, immediate revascularization of the culprit lesion is indicated.
  • Selected patients with STEMI-related cardiogenic shock may benefit from a short-term microaxial flow pump if they fit specific criteria; close attention to vascular complications and renal failure is required.

• In-Hospital Care and Complications

  • Use telemetry for rhythm monitoring in unstable patients and evaluate left ventricular ejection fraction prior to discharge.
  • Mechanical complications (e.g., ventricular septal rupture) require rapid surgical consultation; short-term mechanical circulatory support devices may be a bridge to surgery.

• Secondary Prevention and Discharge

  • Refer all patients to a cardiac rehabilitation program to reduce rehospitalizations and improve functional status. A home-based program is acceptable when center-based options are not feasible.
  • Repeat lipid panel 4 to 8 weeks postdischarge to confirm adequate LDL-lowering.
  • Annual influenza vaccination is recommended to reduce cardiovascular events and mortality.
  • Consider low-dose colchicine in certain post-ACS patients to reduce the risk of recurrent ischemic events if there are no contraindications.
  • Based on one trial, red blood cell transfusion to maintain hemoglobin of 10 g/dL may be reasonable in patients with ACS and acute or chronic anemia who are not actively bleeding.

Conclusion:
Adherence to these recommendations can significantly improve in-hospital and postdischarge outcomes for patients with acute coronary syndromes. By focusing on rapid identification, prompt reperfusion, tailored antithrombotic therapies, aggressive risk factor modification, and ongoing follow-up (including cardiac rehabilitation), clinicians can lower morbidity, mortality, and readmissions. The guideline also underscores the need to balance bleeding and ischemic risks, use high-intensity lipid-lowering strategies, and provide a structured discharge plan for long-term secondary prevention.

2024 VA/DOD Clinical Practice Guideline for Stroke Rehabilitation

26 Jan, 2025 | 17:07h | UTC

Introduction:
This document summarizes the updated 2024 clinical practice guideline (CPG) jointly developed by the U.S. Department of Veterans Affairs (VA) and the U.S. Department of Defense (DOD). It addresses stroke rehabilitation across inpatient, outpatient, and community settings, emphasizing an interdisciplinary approach. The main objective is to provide evidence-based recommendations to guide clinical decision-making and improve functional outcomes and quality of life for adult stroke survivors.

Key Recommendations:

1. Transition to Community
   • Case Management: Suggest using case management services at discharge to enhance activities of daily living (ADLs) and functional independence (“weak for”).
   • Behavioral/Psychosocial Interventions: Recommend psychosocial supports, such as stress management and motivational interviewing, to improve patient and caregiver depression, family function, and overall quality of life (“weak for”).
   • Psychoeducation: Encourage structured education on stroke care and self-management for patients and their caregivers to boost functional independence and social support.
2. Motor Therapy
   • Task-Specific Practice: Strongly recommend repetitive or task-oriented practice to improve motor function, gait, posture, and ADLs (“strong for”).
   • Mirror Therapy: Suggest mirror therapy to improve motor outcomes, ADLs, and unilateral spatial neglect (“weak for”).
   • Rhythmic Auditory Stimulation: Suggest adding external auditory cues (e.g., music or metronome) to assist in gait training (“weak for”).
   • Neuromuscular Electrical Stimulation: Suggest neuromuscular electrical stimulation for enhancing upper- or lower-extremity motor recovery (“weak for”).
   • Botulinum Toxin for Spasticity: Suggest botulinum toxin for focal spasticity, considering patient-specific characteristics and preferences, though evidence shows comparable efficacy to oral baclofen except in ankle spasticity (“weak for”).
3. Dysphagia, Aphasia, and Cognition
   • Dysphagia Rehabilitation:
     • Chin tuck against resistance for swallowing impairment (“weak for”).
     • Respiratory muscle strength training (for those without tracheostomy) to reduce aspiration risk (“weak for”).
   • Aphasia Rehabilitation:
     • No specific intensity level of language therapy is proven superior; tailor therapy duration and frequency to individual needs (“neither for nor against”).
   • Cognitive Outcomes:
     • Current evidence does not support or refute SSRIs for cognitive recovery; consider other individualized cognitive rehabilitation strategies (“neither for nor against”).
   • Unilateral Spatial Neglect:
     • Mirror therapy may help address neglect and improve ADLs (“weak for”).
4. Mental Health
   • Depression Treatment:
     • Suggest SSRIs or SNRIs for patients with established poststroke depression (“weak for”).
     • Recommend psychotherapy (e.g., cognitive behavioral therapy) and consider mindfulness-based therapies for depression following stroke (“weak for”).
   • Prevention of Depression:
     • Suggest against prophylactic antidepressants for preventing poststroke depression due to risk of adverse effects, such as fractures (“weak against”).
5. Telehealth
   • Consider telerehabilitation as an alternative or adjunct to in-person therapy if it aligns with patient preferences and clinical feasibility (“weak for”).
   • Evidence is inconclusive regarding telerehabilitation for dysphagia, aphasia, or caregiver support; use individualized judgment (“neither for nor against”).
6. Noninvasive Brain Stimulation
   • Insufficient evidence to recommend for or against repetitive transcranial magnetic stimulation (rTMS), transcranial direct current stimulation (tDCS), or continuous theta burst stimulation to enhance motor recovery (“neither for nor against”).

Conclusion:
These updated 2024 VA/DOD stroke rehabilitation guidelines underscore the importance of an interdisciplinary and patient-centered approach that integrates medical, psychological, and rehabilitative strategies. Adopting these recommendations—particularly around early case management, targeted motor therapies (task-specific practice, mirror therapy, neuromuscular electrical stimulation), dysphagia interventions, and tailored mental health treatments—can improve functional outcomes, optimize quality of life, and reduce poststroke morbidity.

2024 ACC/AHA Guideline for the Management of Lower Extremity Peripheral Artery Disease

21 Jan, 2025 | 12:44h | UTC

Introduction:
This summary highlights key points from the 2024 ACC/AHA guideline on managing patients with lower extremity peripheral artery disease (PAD). It addresses diagnosis, risk stratification, and treatment strategies to reduce major adverse cardiovascular events (MACE) and major adverse limb events (MALE), focusing on four clinical subsets of PAD—asymptomatic PAD, chronic symptomatic PAD, chronic limb-threatening ischemia (CLTI), and acute limb ischemia (ALI). Its overarching goal is to optimize cardiovascular risk reduction, preserve limb function, and improve quality of life (QOL).

Key Recommendations:

1. Clinical Assessment and Diagnosis
   • Perform a thorough history and physical examination in patients at risk of PAD (e.g., older adults, those with diabetes, hypertension, dyslipidemia, smokers, or known atherosclerosis).
   • Measure the ankle-brachial index (ABI) to establish the diagnosis of PAD; use toe-brachial index (TBI) for patients with noncompressible arteries.
   • Obtain imaging (e.g., duplex ultrasound, CT angiography, MR angiography) when planning revascularization or in cases with inconclusive ABI.
2. Risk Factor Management (Guideline-Directed Medical Therapy)
   • Antiplatelet and Antithrombotic Therapy:
     • Recommend single antiplatelet therapy (e.g., aspirin or clopidogrel) for symptomatic PAD to reduce MACE.
     • Consider low-dose rivaroxaban (2.5 mg twice daily) plus low-dose aspirin in patients at low bleeding risk to reduce MALE.
   • Lipid-Lowering Therapy:
     • Initiate high-intensity statin therapy in all patients with PAD to reduce cardiovascular and limb events.
     • Add ezetimibe or a PCSK9 inhibitor if LDL-C levels remain above target (≥70 mg/dL).
   • Blood Pressure Control:
     • Target a systolic blood pressure <130 mm Hg in patients with PAD; ACE inhibitors or angiotensin-receptor blockers can further reduce cardiovascular risk.
   • Diabetes Management:
     • Optimize glycemic control, especially in CLTI; newer agents (e.g., SGLT2 inhibitors, GLP-1 receptor agonists) can reduce cardiovascular risk in PAD with type 2 diabetes.
   • Smoking Cessation:
     • Strongly advise cessation of all forms of tobacco and nicotine; offer pharmacotherapy (e.g., varenicline, bupropion, nicotine replacement) and behavioral counseling.
3. Exercise Therapy
   • Supervised Exercise Therapy (SET):
     • A cornerstone of care for patients with claudication to improve walking performance and quality of life.
     • Generally performed 3 times per week for at least 12 weeks in a supervised setting (e.g., cardiac rehab facility).
   • Structured Community-Based (Home-Based) Programs:
     • Include regularly prescribed walking regimens, with periodic clinical follow-up and coaching to promote adherence.
4. Revascularization for Chronic Symptomatic PAD
   • Initial Approach:
     • Offer revascularization (endovascular, surgical, or hybrid) if patients have functionally limiting claudication that fails to improve with medical therapy and structured exercise.
   • Endovascular vs. Surgical:
     • Select a strategy based on lesion characteristics, availability of adequate vein conduit, and patient comorbidities.
     • Combining revascularization with supervised exercise generally yields better functional outcomes.
   • Common Femoral Disease:
     • Surgical endarterectomy remains a highly durable option.
     • Endovascular approaches can be considered for select cases, particularly where surgical risk is high or anatomy is favorable.
5. Management of Chronic Limb-Threatening Ischemia (CLTI)
   • Team-Based Care:
     • Collaborate with vascular specialists, podiatrists, wound-care experts, and other clinicians for optimal outcomes.
   • Revascularization Goals:
     • Prevent amputation, heal wounds, and reduce rest pain.
     • Both endovascular and surgical methods can be effective; selection depends on anatomy, available vein conduit, and patient risk profile (e.g., the BEST-CLI and BASIL-2 trials guide decisions).
   • Adjunctive Wound Care:
     • Use local wound management (e.g., debridement, negative pressure therapy, offloading) to facilitate healing.
     • Treat infection aggressively; urgent revascularization plus antibiotics is essential.
   • Pressure Offloading:
     • Custom footwear and casts/shoes reduce plantar pressure and help prevent or heal foot ulcers.
6. Acute Limb Ischemia (ALI)
   • Immediate Recognition:
     • Suspect ALI in patients with sudden onset of pain, pallor, pulselessness, paresthesia, and paralysis.
     • Determine limb viability (categories I–III) rapidly.
   • Treatment:
     • Begin anticoagulation (e.g., IV unfractionated heparin) unless contraindicated.
     • Urgent revascularization (surgical embolectomy, catheter-directed thrombolysis, or mechanical thrombectomy) for salvageable limbs.
     • Monitor for compartment syndrome and consider fasciotomy if needed.
7. Preventive Foot Care
   • Educate patients on self-inspection, daily hygiene, and protective footwear.
   • Screen regularly for high-risk conditions (neuropathy, calluses, deformities, infection).
   • Promptly address any foot lesions to avoid progression to ulceration, infection, or gangrene.
8. Longitudinal Follow-Up
   • Schedule regular visits to monitor:
     • Cardiovascular risk factor control (lipids, blood pressure, glycemic targets, smoking).
     • Lower extremity symptoms, functional status, and foot health.
     • Need for repeat ABI, duplex ultrasound, or imaging after revascularization to detect restenosis.
   • Reinforce adherence to structured exercise, medication regimens, and foot care strategies.

Conclusion:
These recommendations underscore the importance of personalized, multidisciplinary care that addresses both cardiovascular and limb-related outcomes in patients with lower extremity PAD. A combination of comprehensive risk-factor modification, supervised or structured exercise programs, and strategic use of revascularization can significantly reduce the risk of major limb loss, improve symptoms, and enhance QOL. Ongoing follow-up is critical to detect disease progression, optimize therapy, and maintain patient engagement in preventative care.

Management of Cervical Artery Dissection: Key Points From the AHA Scientific Statement

21 Jan, 2025 | 11:05h | UTC

Introduction:
This document summarizes the American Heart Association (AHA) scientific statement on cervical artery dissection (CAD), an important cause of ischemic stroke, especially in younger and middle-aged adults. Cervical artery dissection often presents with nonspecific symptoms—such as headache, neck pain, or partial Horner syndrome—but can lead to serious neurological deficits. Early recognition, targeted imaging, appropriate acute treatment, and well-informed decisions on antithrombotic therapy are essential to optimize patient outcomes.

Key Recommendations:

• Epidemiology and Risk Factors
  • CAD accounts for up to 25% of ischemic strokes in adults under 50 years of age, with a slightly higher incidence in men but lower peak age in women.
  • Risk factors include genetic predispositions (eg, connective tissue disorders), anatomic variants (elongated styloid process, vascular tortuosity), minor cervical trauma, and comorbidities such as hypertension or fibromuscular dysplasia.
• Diagnosis and Imaging
  1. Clinical Suspicion
     • Suspect CAD in younger adults with new or worsening neck pain, headache, pulsatile tinnitus, partial Horner syndrome, or cranial nerve involvement, especially if there is a history of recent minor neck trauma or manipulation.
     • Up to 8%–12% of patients may have isolated neck or head pain with no initial ischemic signs.
  2. Imaging Modalities
     • Magnetic Resonance Imaging (MRI)/Magnetic Resonance Angiography (MRA): High-resolution, fat-suppressed T1-weighted sequences are useful for detecting intramural hematoma.
     • Computed Tomography Angiography (CTA): Good sensitivity and specificity for luminal abnormalities and can detect intraluminal thrombus. Avoid false positives by distinguishing imaging artifacts from true double lumens or intimal flaps.
     • Conventional Digital Subtraction Angiography (DSA): Historically the gold standard but reserved for equivocal cases because of procedure-related risks (eg, iatrogenic dissection).
     • Ultrasound with Color Doppler: Operator-dependent but helpful for serial follow-up of vessel remodeling.
  3. Additional Diagnostic Testing
     • Connective Tissue Disorders: Consider genetic counseling if physical exam, family history, or recurrent dissections suggest a monogenic disorder (eg, vascular Ehlers-Danlos).
     • Screening for Fibromuscular Dysplasia (FMD): Patients with CAD, especially those with hypertension or evidence of FMD in other vascular beds, may warrant renal artery imaging.
     • Aortic and Intracranial Imaging: Aortic root dilation and cerebral aneurysms may be more prevalent in CAD; consider advanced imaging (eg, MRA) based on clinical judgment.
• Hyperacute and Acute Stroke Management
  1. Intravenous Thrombolysis (IVT):
     • IVT (alteplase or tenecteplase) remains reasonable for otherwise eligible acute ischemic stroke patients, with no specific evidence of higher hemorrhagic risk in CAD. Caution is advised if there is intracranial extension of the dissection or other significant bleeding risk factors.
  2. Mechanical Thrombectomy:
     • Recommended for large-vessel occlusion in CAD patients who meet standard thrombectomy criteria. Tandem lesions (extracranial dissection and intracranial occlusion) can be addressed via retrograde (intracranial first) or antegrade (extracranial first) approach, with similar overall outcomes reported.
  3. Acute or Subacute Stenting:
     • May be considered in selected cases of severe flow-limiting stenosis leading to distal hypoperfusion or in persistent ischemia despite optimal medical therapy. Stenting in tandem occlusions can improve reperfusion but carries added risks (in-stent restenosis, stent thrombosis, or need for dual antiplatelet therapy).
• Antithrombotic Therapy for Secondary Stroke Prevention
  1. Rationale for Early Treatment:
     • Artery-to-artery embolization underpins most CAD-related ischemic events. Early initiation of antithrombotics (ideally within the first 24–72 hours) reduces further embolic risk.
  2. Choice of Agent: Antiplatelet vs Anticoagulant
     • When to Prefer Anticoagulation:
       • Patients with high-risk imaging features: severe stenosis (>50%–70%), intraluminal thrombus, occlusion, multiple or early recurrent dissections.
       • Traditional option is heparin bridging to Vitamin K antagonist (target INR ≈2–3), but direct oral anticoagulants (DOACs) can be considered based on patient profile and preference.
     • When to Prefer Antiplatelet Therapy:
       • Patients with lower stroke risk (no significant stenosis, no intraluminal thrombus) or higher bleeding risk (large infarct, hemorrhagic transformation, intradural extension).
       • Aspirin monotherapy is typical; a short course of dual antiplatelet therapy (aspirin + clopidogrel) for 21–90 days can be considered if minor stroke/TIA criteria apply and bleeding risk is acceptable.
  3. Practical Start-Up and Monitoring:
     • Begin therapy as soon as deemed safe, ideally after hemorrhagic complications are excluded.
     • For VKA: bridge with heparin (IV unfractionated or low–molecular-weight) for at least 5 days until INR is therapeutic for ≥24 hours.
     • Regularly monitor clinical response and, if relevant, INR in anticoagulated patients.
  4. Duration of Therapy:
     • Minimum 3–6 months of antithrombotics, with vessel imaging at follow-up (eg, 3 or 6 months) to assess for healing or persistent dissection.
     • Decisions to extend antithrombotic therapy past the 6-month mark may be considered in the context of an individual’s overall vascular risk factor profile and in the context of neuroimaging features as remodeling occurs.
     • Consider extended or indefinite therapy (often antiplatelet) if persistent stenosis, high-risk anatomic factors, or recurrent dissections occur.
• Risk of Recurrent Dissection and Lifestyle Precautions
  • Recurrence rates range from 1% to 2% per year but are higher in the first few months post-dissection. Fibromuscular dysplasia and younger age are associated with increased recurrence risk.
  • It is reasonable to advise patients to avoid high-risk neck activities (eg, contact sports, extreme neck manipulation) for 1–6 months or until imaging confirms vessel healing. In those with a known connective tissue disorder or recurrent dissection, lifelong caution is appropriate.
• Follow-Up Imaging and Management of Dissecting Aneurysms
  • Recanalization most often occurs by 6–12 months; persistent occlusions or stenoses beyond 12 months rarely recanalize further.
  • Dissecting aneurysms form or enlarge in some cases but seldom rupture. Antithrombotic choice does not appear to affect aneurysm resolution rates.
  • Endovascular or surgical interventions are reserved for enlarging or symptomatic aneurysms causing compression or other complications.

Conclusion: Cervical artery dissection warrants vigilant clinical recognition, prompt imaging, and individualized treatment strategies. Early antithrombotic therapy—whether anticoagulation or antiplatelet—plays a critical role in preventing stroke. Decisions should reflect both the patient’s hemorrhagic risk and the presence of imaging features predictive of stroke. Mechanical thrombectomy and, in selected cases, stenting are viable acute interventions for high-risk presentations. Although recurrences are uncommon, thoughtful follow-up imaging, patient education, and avoidance of high-risk neck activities are central to minimizing future dissections and optimizing outcomes.

Screening for Osteoporosis to Prevent Fractures: Updated USPSTF Guidelines

18 Jan, 2025 | 15:19h | UTC

Introduction: This document summarizes the 2025 US Preventive Services Task Force (USPSTF) guideline on screening for osteoporosis to prevent fragility fractures. Osteoporosis, characterized by low bone mass and decreased bone quality, can lead to fractures that impair independence, increase morbidity, and raise mortality. The revised guidance builds on evidence that screening in select populations reduces fracture risk. Although the Task Force finds moderate net benefit for screening certain groups, it concludes that evidence remains insufficient to assess benefits and harms in other segments.

Key Recommendations:

1. Population and Rationale:
   • Women 65 years or older: The USPSTF concludes with moderate certainty that screening for osteoporosis in this age group leads to moderate net benefit for preventing osteoporotic fractures.
   • Postmenopausal women younger than 65 years at increased risk: Screening is recommended if a formal risk assessment or clinical risk factors indicate elevated risk, as moderate certainty suggests moderate benefit.
   • Men: The current evidence is insufficient to establish the balance of benefits and harms of screening men without known osteoporosis or prior fragility fractures.
2. Screening Methods:
   • The USPSTF identifies central dual-energy x-ray absorptiometry (DXA) of the hip or lumbar spine as the key screening test.
   • In younger postmenopausal women, a two-step approach is suggested: (1) assess risk factors (e.g., low body weight, smoking, parental history of hip fracture); (2) apply a validated tool (e.g., Osteoporosis Risk Assessment Instrument [ORAI] or Osteoporosis Self-assessment Tool [OST]) to determine who should proceed to DXA.
   • Tools such as FRAX may be used with or without BMD input to estimate 10-year fracture probability, but clinicians should be aware that tool accuracy and calibration vary by age, race/ethnicity, and underlying data sources.
3. Screening Intervals:
   • Current data do not clearly define an optimal interval for repeated screening.
   • Some evidence suggests little added value in repeating BMD tests within four to eight years if initial results are normal or only mildly low.
4. Management Following a Positive Screening Result:
   • After osteoporosis is confirmed, patients should be counseled on modifiable risk factors (e.g., smoking cessation, fall prevention) and assessed for pharmacotherapy.
   • Approved treatments (e.g., bisphosphonates, denosumab) have demonstrated benefit in reducing vertebral, hip, and other major fractures.
5. Harms of Screening and Treatment:
   • Screening anxiety and overdiagnosis are minimal concerns, though data are limited.
   • Bisphosphonate use has not been associated with significant excess serious adverse events in short- to medium-term trials, but rare events (e.g., atypical femur fractures, osteonecrosis of the jaw) remain possible with long-term use.
   • Denosumab reduces multiple fracture outcomes, though discontinuation can lead to rebound bone loss and increased risk of vertebral fractures without follow-up management.
   • The USPSTF underscores that treatment decisions should be individualized, especially in diverse populations and those with complex comorbidities.

Conclusion: These updated recommendations highlight the importance of osteoporosis screening in women 65 years or older and in younger postmenopausal women at higher fracture risk. Early detection with central DXA, informed by clinical risk tools, can reduce fracture incidence and related burdens. Further research is needed to clarify optimal screening intervals, the role of screening in men, and long-term treatment strategies. In the meantime, clinicians should collaborate with patients to personalize screening and treatment plans, considering both clinical risks and patient preferences.

Diagnosis and Management of Eosinophilic Esophagitis: Updated ACG Clinical Guideline Summary

14 Jan, 2025 | 13:46h | UTC

Introduction: This summary highlights the updated American College of Gastroenterology (ACG) Clinical Guideline on eosinophilic esophagitis (EoE), a chronic, immune-mediated disease of the esophagus characterized by esophageal eosinophilia and clinical symptoms of esophageal dysfunction. Over the last decade, the incidence and prevalence of EoE have increased significantly. This guideline incorporates new diagnostic strategies, therapeutic advances, and monitoring practices, aiming to improve patient outcomes and minimize disease complications such as strictures, food impactions, and impaired quality of life. The document underscores the importance of assessing both the inflammatory and fibrostenotic components of EoE through endoscopy, histopathology, and symptom evaluation.

Key Recommendations:

• Diagnosis:
  • Diagnose EoE when patients present with symptoms of esophageal dysfunction and at least 15 eosinophils per high-power field (eos/hpf) on esophageal biopsies, after exclusion of other causes of esophageal eosinophilia.
  • Use a systematic scoring tool such as the EoE Endoscopic Reference Score (EREFS) to assess edema, rings, exudates, furrows, and strictures at every endoscopy.
  • Obtain at least six esophageal biopsies from two or more levels (e.g., distal and proximal) to minimize diagnostic miss rates; quantify peak eosinophil counts in each specimen.
• Pharmacologic Therapy:
  1. Proton Pump Inhibitors (PPIs):
     • Consider high-dose PPIs (e.g., twice daily) as a first-line treatment option. Although originally used for acid suppression, PPIs also reduce eotaxin-3 expression and improve esophageal barrier function in EoE.
     • Maintain therapy long term in patients who respond, as discontinuation frequently leads to disease recurrence.
  2. Topical Corticosteroids (Swallowed Steroids):
     • Budesonide or fluticasone can be delivered via specially formulated suspensions/tablets or by swallowing inhaler medication.
     • Expect histologic remission rates of around 60%–70%.
     • Oral/esophageal candidiasis is the most common adverse event. Routine adrenal suppression testing is generally not necessary for short-term use.
  3. Dietary Elimination:
     • Empiric elimination diets (e.g., 2-food or 6-food elimination) help identify specific food triggers. Histologic remission rates can exceed 70%, particularly with the 6-food approach.
     • Less-restrictive diets (e.g., milk-only elimination) may be tried first (the “step-up” approach).
     • Do not rely on currently available skin prick or Ig-based tests to guide elimination diets, as these have poor predictive value for EoE triggers.
  4. Biologic Therapy:
     • Dupilumab (anti–IL-4 receptor alpha) is recommended in adolescents and adults (≥12 years, ≥40 kg) and is now approved for children as young as 1 year (≥15 kg) with moderate to severe, PPI-refractory EoE. Expect significant histologic, endoscopic, and symptom improvements in most patients, along with an overall favorable safety profile.
     • Other biologics (e.g., cendakimab, benralizumab, mepolizumab) remain under investigation; current data are insufficient for routine clinical use.
  5. Esophageal Dilation:
     • Perform endoscopic dilation to treat symptomatic strictures or narrow-caliber esophagi. Dilation reduces dysphagia promptly but does not alter the underlying inflammation.
     • Combine dilation with anti-inflammatory therapy to address the disease’s inflammatory component and help prevent recurrent stricture formation.
• Maintenance and Monitoring:
  • Because EoE is chronic, continue effective therapy over the long term. Abrupt cessation of treatment often leads to relapses in symptoms and inflammation.
  • Evaluate treatment response by assessing symptoms, endoscopic findings (e.g., EREFS), and histopathology (peak eosinophil counts).
  • A target of <15 eos/hpf and near-normal endoscopic appearance (EREFS ≤2) is commonly used to define remission, although some patients aim for histologic normalization.
  • In children, ensure regular assessment of growth, development, and feeding behaviors. Referral to a nutritionist or feeding therapist is recommended if feeding difficulties or failure to thrive are present.

Conclusion: These updated ACG guidelines underscore the importance of a comprehensive, individualized approach to EoE that encompasses diagnosis, treatment of the inflammatory state, dilation of fibrotic strictures, and ongoing monitoring to maintain long-term remission. The introduction of biologics (particularly dupilumab) expands treatment options for patients nonresponsive to PPIs or topical steroids. Clinicians should adopt a structured assessment strategy—integrating clinical history, endoscopic scoring, and histological evaluation—to guide therapy selection, document treatment response, and prevent complications. With improved understanding of disease pathogenesis and evolving therapeutic tools, outcomes for patients with EoE are expected to continue to improve.

AGA Clinical Practice Update on Potassium-Competitive Acid Blockers for Foregut Disorders

14 Jan, 2025 | 11:20h | UTC

Introduction: This summary presents the key points of a recently published American Gastroenterological Association (AGA) Clinical Practice Update that reviews the role of potassium-competitive acid blockers (P-CABs) in managing acid-related foregut disorders. P-CABs offer a unique mechanism of action compared with proton pump inhibitors (PPIs) and histamine_2-receptor antagonists, potentially delivering more rapid and prolonged acid suppression. The aim of this review is to provide clinicians with evidence-based guidance on P-CAB use in gastroesophageal reflux disease (GERD), Helicobacter pylori (HP) infection, and peptic ulcer disease (PUD), clarifying their benefits, limitations, and potential place in therapy.

Key Recommendations:

1. Overall Use of P-CABs: Clinicians should generally avoid using P-CABs as first-line therapy for acid-related conditions unless there is proven clinical superiority over PPIs. Factors such as higher costs, more limited availability, and less comprehensive long-term safety data often outweigh the advantages of P-CABs, particularly for milder disease.
2. Cost-Effectiveness: Current U.S. costs for P-CABs may not justify routine first-line use, even if modest clinical benefits exist compared with double-dose PPIs. Long-term data on cost-effectiveness and safety remain limited.
3. Nonerosive GERD: P-CABs are not recommended as initial treatment for heartburn without endoscopic findings (uninvestigated GERD) or nonerosive reflux disease. Clinicians may consider P-CABs for patients who have confirmed acid-related reflux and show inadequate response to twice-daily PPI therapy.
4. On-Demand Therapy: Rapid onset of P-CABs suggests potential utility in on-demand regimens for patients previously responsive to acid suppression. While limited data show efficacy compared to placebo, further trials against PPIs and histamine_2-receptor antagonists are needed before making firm recommendations.
5. Mild Erosive Esophagitis (LA Grade A/B): For Los Angeles classification (LA) grade A/B erosive esophagitis (EE), standard PPIs remain first-line treatment. P-CABs may be an option for patients whose esophagitis persists despite optimal PPI therapy, but initial evidence does not support routine, front-line use.
6. Severe Erosive Esophagitis (LA Grade C/D): In more advanced EE, P-CABs can be considered for healing and maintenance, as some data suggest superior efficacy compared with standard-dose PPI. However, the lack of comparative trials with high-dose PPIs and the higher cost of P-CABs complicate their routine use as first-line therapy in severe disease.
7. HP Eradication: P-CAB–based regimens for H pylori treatment often show higher or noninferior cure rates compared with PPI-based therapies, particularly in the presence of clarithromycin resistance. The more potent and prolonged acid suppression may enhance antibiotic efficacy, supporting the use of P-CABs in most patients with HP infection.
8. Peptic Ulcer Disease Treatment and Prophylaxis: Current evidence indicates that P-CABs are noninferior to PPIs for ulcer healing and prevention of recurrent ulcers in patients requiring aspirin or nonsteroidal anti-inflammatory drugs. However, in light of their higher cost and similar clinical outcomes, P-CABs should not replace PPIs as first-line therapy unless patients fail PPI regimens.
9. Ulcer Bleeding: Although data are preliminary, P-CABs may be useful following endoscopic hemostasis in high-risk ulcer bleeding. Their rapid and potent acid suppression suggests they could match or exceed high-dose PPI efficacy, but more robust comparative trials are needed.

Conclusion: Potassium-competitive acid blockers represent a valuable therapeutic option in selected patients who do not respond adequately to traditional PPIs or who have complex acid-related conditions (such as severe erosive esophagitis or antibiotic-resistant H pylori). While their more rapid onset of action and prolonged effect can be advantageous, the limited availability of long-term safety data, cost considerations, and lack of substantial clinical superiority over standard or double-dose PPIs in many indications currently limit widespread adoption. Further investigations are needed to establish cost-effectiveness, clarify safety profiles, and identify specific patient populations most likely to benefit from P-CABs.

Comprehensive Glycemic Goals and Hypoglycemia Management in Diabetes: 2025 ADA Standards

13 Jan, 2025 | 12:39h | UTC

Introduction: This summary provides key points from the American Diabetes Association’s (ADA) 2025 guidance on glycemic targets, monitoring, and hypoglycemia management in type 1 and type 2 diabetes. It emphasizes individualized A1C goals, the clinical use of continuous glucose monitoring (CGM)—a system that measures interstitial glucose levels throughout the day—and the prevention and treatment of hypoglycemia. The main objective is to help clinicians optimize glucose control, reduce acute and chronic complications, and improve patient outcomes.

Key Recommendations:

1. Individualized Glycemic Targets
   • An A1C goal of <7% (<53 mmol/mol) is generally appropriate for many nonpregnant adults without frequent or severe hypoglycemia.
   • Lower or higher A1C goals may be appropriate in specific situations. For example:
     • Comorbidities: Individuals with significant cardiovascular disease, kidney dysfunction, or other conditions may benefit from a more conservative A1C target (e.g., <8%), balancing the risks of intensive treatment (such as hypoglycemia) against the benefits of tighter control.
     • Hypoglycemia Risk: Those with a history of severe or frequent hypoglycemia might need to relax A1C targets to avoid life-threatening low glucose episodes. In contrast, highly motivated patients with robust hypoglycemia awareness and access to advanced monitoring tools could safely aim for A1C closer to 6%.
     • Life Expectancy: Younger, healthier individuals with fewer complications can pursue tighter A1C targets because they have time to benefit from reduced microvascular and macrovascular risks. Older adults or those with serious illnesses and limited life expectancy may adopt higher A1C goals to reduce treatment burden and prevent hypoglycemic events.
2. Monitoring Glycemic Status
   • A1C Testing: Measure at least twice a year when glucose levels are stable and quarterly (or more often) when adjusting therapy or when targets are not met. If A1C is unreliable (e.g., hemoglobin variants), fructosamine or glycated albumin may be used.
   • Continuous Glucose Monitoring (CGM): CGM devices automatically measure glucose day and night, providing valuable data for clinical decision-making. Key CGM metrics include:
     • Time in Range (TIR): The percentage of readings between 70 and 180 mg/dL, with >70% as a common target in most nonpregnant adults.
     • Time Below Range: Ideal is <4% of readings under 70 mg/dL and <1% for older adults.
     • Time Above Range: Common goals are <25% for mild hyperglycemia and <5% for severe hyperglycemia, though this may vary with age and comorbidities.
   • When refining diabetes therapies, review CGM reports (e.g., ambulatory glucose profiles) to identify patterns of high or low glucose. This helps personalize adjustments to medications, diet, and exercise. For instance, consistent nocturnal hypoglycemia might prompt a reduction or timing change of basal insulin, while excessive morning hyperglycemia may require earlier medication dosing or lifestyle interventions.
3. Hypoglycemia Prevention and Management
   • Classification: Level 1 (<70 mg/dL), Level 2 (<54 mg/dL), and Level 3 (severe, requiring assistance).
   • Assessment: At each visit, review hypoglycemia history, symptom awareness, and potential triggers (e.g., exercise, medication errors, missed meals).
   • Treatment: In conscious patients, use 15 g of fast-acting carbohydrates (glucose tablets or similar). Recheck glucose in 15 minutes and repeat if still low.
   • Glucagon Prescription: Recommended for anyone on insulin or otherwise high-risk. Ready-to-inject or nasal glucagon formulations are preferred for ease of use.
   • Therapeutic Adjustment: Deintensify or modify medications (insulin, sulfonylureas) if patients experience recurrent moderate or any severe hypoglycemia.
4. Hyperglycemic Crises
   • DKA and HHS: Promptly recognize and treat diabetic ketoacidosis (DKA) and hyperglycemic hyperosmolar state (HHS), especially in patients presenting with nausea, vomiting, dehydration, or altered mental status.
   • Prevention: Provide “sick day” advice on ketone checks, hydration, and insulin adjustments during illness. Recurrent crises often reflect limited access to medications or inadequate education; address these barriers to reduce re-hospitalizations.
5. Long-Term Impact on Complications
   • Early intensive glycemic control significantly lowers the risk of microvascular complications (retinopathy, nephropathy, neuropathy) in both type 1 and type 2 diabetes.
   • Long-term studies in type 1 diabetes show that sustained glucose management can reduce cardiovascular events. In type 2 diabetes, the addition of newer agents (e.g., GLP-1 receptor agonists or SGLT2 inhibitors) can further decrease cardiovascular and kidney risks, independent of current A1C levels.

Conclusion: The 2025 ADA Standards reinforce the need for customized glycemic targets, informed by comorbidities, hypoglycemia risk, life expectancy, and patient preferences. Using a combination of A1C and CGM data provides a more complete picture of glucose patterns and helps clinicians fine-tune therapies. Preventing hypoglycemia through medication adjustments, structured self-management education, and tailored CGM strategies is paramount. Overall, consistent and individualized glucose control offers better long-term outcomes, fewer complications, and improved quality of life for individuals with diabetes.

2024 Focused Guideline Update on Corticosteroid Use in Sepsis, ARDS, and Community-Acquired Pneumonia

13 Jan, 2025 | 11:04h | UTC

Introduction: This summary presents the key points from a 2024 focused update of the guidelines on corticosteroid use for hospitalized adult patients with sepsis, acute respiratory distress syndrome (ARDS), and community-acquired pneumonia (CAP). Developed by a panel of international experts in critical care, endocrinology, and methodology, the update aims to incorporate new evidence into recommendations regarding dosage, duration, and timing of corticosteroid therapy. Pediatric-specific recommendations could not be made due to limited data.

Key Recommendations:

1. Sepsis and Septic Shock
   • Conditional Recommendation: In adult patients with septic shock requiring vasopressor support, the panel suggests administering corticosteroids (typically hydrocortisone 200–300 mg/day IV for about 5–7 days, with or without fludrocortisone).
   • Strong Recommendation Against High Dose/Short Duration: High-dose corticosteroids (> 400 mg/day hydrocortisone equivalent given for fewer than 3 days) are not recommended, as they confer increased risk of adverse effects without demonstrating benefit.
2. Acute Respiratory Distress Syndrome (ARDS)
   • Conditional Recommendation: In adult patients hospitalized with ARDS (including those with COVID-19 ARDS), the panel suggests using corticosteroids (e.g., methylprednisolone, dexamethasone, or hydrocortisone) to lower short-term mortality and potentially reduce duration of mechanical ventilation. No specific agent or dosing regimen is mandated; choices should be guided by clinical judgment and patient context.
3. Community-Acquired Pneumonia (CAP)
   • Strong Recommendation (Severe CAP): In adults hospitalized with severe bacterial CAP, the panel recommends corticosteroids (commonly moderate-dose IV hydrocortisone or methylprednisolone for 5–7 days). Recent data indicate a clear mortality benefit in these high-risk patients.
   • No Recommendation (Less Severe CAP): For adults with less severe bacterial CAP, current evidence is inconclusive regarding mortality benefit. Although some findings suggest improvements in certain outcomes, the panel reached no consensus on whether corticosteroids should be routinely administered.

Conclusion: These updated guidelines emphasize the overall safety and potential survival benefits of corticosteroids in specific populations with critical illness, particularly those with septic shock, ARDS, or severe CAP. For each condition, the recommendations balance desirable effects—such as reduced mortality, organ dysfunction, and length of hospital stay—against possible harms, including hyperglycemia and neuromuscular weakness. Evidence remains insufficient to support pediatric guidance or clarify whether less severe CAP consistently merits treatment. Future research should address optimal dosing strategies, pediatric outcomes, long-term adverse effects, and potential cost-effectiveness across diverse healthcare settings.

ATS Guidelines on Invasive Pulmonary Aspergillosis and Antifungal Strategies in Critically Ill Adults

7 Jan, 2025 | 12:29h | UTC

Introduction: This summary provides an overview of a recent American Thoracic Society clinical practice guideline addressing two core questions in adult pulmonary and critical care practice. First, it examines whether combination therapy with a mold-active triazole (most data concern voriconazole, though newer agents such as isavuconazole or posaconazole may also be considered) plus an echinocandin (specifically caspofungin, micafungin, or anidulafungin) offers added benefit over mold-active triazole monotherapy for patients with proven or probable invasive pulmonary aspergillosis (IPA). Second, it evaluates whether routine use of prophylactic or empiric antifungal agents against Candida species is advisable in critically ill, nonneutropenic, nontransplant patients at risk of invasive candidiasis (IC). By synthesizing available evidence using the GRADE approach, this guideline aims to support clinicians in optimizing therapeutic strategies and improving patient outcomes in these complex infections.

Key Recommendations:

Initial Combination Therapy vs. Monotherapy for IPA

• For patients with proven or probable IPA, the guideline makes a conditional recommendation, meaning the best choice isn’t entirely clear. Both initial combination therapy (mold-active triazole + echinocandin) and monotherapy (mold-active triazole alone) are considered reasonable options.
• Evidence stems primarily from studies in hematologic malignancy (HM) or hematopoietic stem cell transplant (HSCT) recipients, with mixed findings in observational cohorts and a key randomized trial favoring combination therapy, particularly in a subgroup diagnosed by positive galactomannan assays.
• When critical illness or triazole resistance is a concern, combination therapy may be considered, but there is insufficient evidence to categorically endorse one approach over the other.

Prophylactic or Empiric Antifungal Therapy for Candida in Critically Ill Patients

• In nonneutropenic, nontransplant adult ICU patients at risk for IC, the guideline makes a conditional recommendation against routinely using prophylactic or empiric antifungal therapy. This means the benefits of withholding these treatments likely outweigh the risks, but there’s still some uncertainty.
• Low-quality evidence from multiple randomized controlled trials showed no significant mortality benefit in administering antifungals prophylactically or empirically compared with placebo.
• Although IC carries substantial morbidity and mortality, its overall incidence in this population remains low, and ongoing surveillance or targeted diagnostics may be preferable to universal antifungal administration.

Conclusion: The panel emphasizes that these recommendations should be applied with clinical judgment, especially in patients with severe disease, likely high fungal burden, or concerns for antifungal resistance. Combination therapy for IPA may be particularly relevant when critical illness or limited triazole efficacy is suspected. Meanwhile, prophylactic or empiric anti-Candida therapy in the broader ICU setting does not appear to substantially reduce mortality. Continued advances in rapid diagnostics, close monitoring of local resistance patterns, and new antifungal agents may further refine best practices. Future research should focus on validating these findings in diverse patient populations, exploring novel combination regimens, and establishing more precise risk assessments for IC in the ICU.

Joint ATS/CDC/ERS/IDSA Guideline Recommends Shorter, All-Oral Regimens for Drug-Susceptible and Drug-Resistant TB

5 Jan, 2025 | 11:30h | UTC

Introduction: This summary outlines new clinical practice guidelines from the American Thoracic Society, U.S. Centers for Disease Control and Prevention, European Respiratory Society, and Infectious Diseases Society of America on updated treatment regimens for tuberculosis (TB) in low-incidence settings. These recommendations build on recent clinical trials, World Health Organization (WHO) guidance, and were developed using the GRADE and GRADE-ADOLOPMENT methodology. The guidelines aim to shorten treatment duration, reduce pill burden, and improve patient outcomes for both drug-susceptible (DS) and drug-resistant (DR) TB, and they apply to settings where mycobacterial cultures, molecular and phenotypic drug susceptibility tests, and radiographic studies are routinely available. A separate news release from CIDRAP highlights the significance of these shorter, all-oral regimens for adults and children. Directly observed therapy (DOT) remains the standard of care.

Key Recommendations:

Four-Month Regimen for DS-TB in Adults:

• For people aged 12 years or older with isoniazid- and rifampin-susceptible pulmonary TB, a new four-month regimen of isoniazid, rifapentine, moxifloxacin, and pyrazinamide (2HPZM/2HPM) is conditionally recommended. This shortened course is based on a large, randomized trial (Study 31/A5349) demonstrating noninferior efficacy compared to the standard six-month regimen (84.6% vs 85.4% cure, respectively), no increase in adverse events, and potential benefits in completion rates. Exclusions include TB meningitis and other complicated forms of extrapulmonary TB, and clinicians should obtain rapid fluoroquinolone susceptibility tests before initiating this regimen.

Four-Month Regimen for DS-TB in Children:

• For children and adolescents aged 3 months to 16 years with nonsevere, drug-susceptible pulmonary TB, a four-month regimen of isoniazid, rifampin, pyrazinamide, and ethambutol for the initial phase, followed by isoniazid and rifampin, is strongly recommended. Evidence from the SHINE trial showed high success (97.1% vs 96.9%) and similar safety with the shorter course compared to the 6-month regimen. Nonsevere TB generally excludes extensive cavitary disease, advanced extrapulmonary TB, or complicated forms. Close clinical and radiographic follow-up is important to confirm effective cure.

Six-Month BPaL Regimen for Rifampin-Resistant, Fluoroquinolone-Resistant or Intolerant TB:

• For rifampin-resistant (RR) pulmonary TB with resistance or patient intolerance to fluoroquinolones in adolescents aged 14 and older and adults, a six-month all-oral bedaquiline, pretomanid, and linezolid (BPaL) regimen is strongly recommended, replacing much longer regimens that often included injectables. Clinical trials (Nix-TB, ZeNix) demonstrated higher cure rates and lower toxicity with this regimen compared to longer regimens, though vigilance is needed for linezolid-related adverse events (e.g., neuropathy, myelosuppression). Baseline and monthly lab and ECG checks are advised.

Six-Month BPaLM Regimen for Rifampin-Resistant, Fluoroquinolone-Susceptible TB:

• For RR pulmonary TB that remains fluoroquinolone-susceptible in adolescents aged 14 and older and adults, a six-month bedaquiline, pretomanid, linezolid, and moxifloxacin (BPaLM) regimen is strongly recommended over traditional 15-month or longer regimens in patients with MDR/RR-TB. Data from the TB-PRACTECAL trial showed high success rates and fewer serious adverse events. BPaLM is the first-line recommendation for this group. Close monitoring of cardiac status (QTc prolongation) and blood counts is advised.

Both BPaL and BPaLM regimens require detailed drug susceptibility testing and cautious management of potential drug–drug interactions, particularly for patients with comorbidities or HIV infection. Of note, the certainty of evidence for the outcomes in the DR-TB trials was rated as very low, due to multiple factors including bias, small event numbers, lack of blinding, and inconsistent outcomes.

Conclusion: These new recommendations markedly shorten TB treatment courses for adults and children in low-incidence settings with access to appropriate diagnostic tools, while avoiding injectables and reducing serious toxicities. By replacing older, more complex regimens with all-oral, shorter-duration therapy, and using DOT as the standard of care, the guidelines aim to improve adherence, lessen the burden on healthcare systems, and enhance patient quality of life. Ongoing research will further refine dosing, safety for special populations (e.g., pregnant individuals), and the role of advanced drug susceptibility testing.

Managing Autonomic Dysfunction, Pain, and Sleep Disturbances in Parkinson’s Disease: Key Points from the German Society of Neurology Guideline

5 Jan, 2025 | 11:00h | UTC

Introduction: This text summarizes a practice-oriented 2023 guideline from the German Society of Neurology addressing non-motor manifestations of Parkinson’s disease (PD). The guideline focuses on evidence-based approaches for diagnosing and treating autonomic failure (including urogenital, cardiovascular, and gastrointestinal dysfunction), pain, and sleep disturbances—problems that often reduce quality of life and accelerate disease progression. The guideline was developed using PICO (Patient, Intervention, Comparison, Outcome) questions, comprehensive literature searches, and a consensus process among German Parkinson’s experts. By presenting stepwise recommendations, the guideline aims to help clinicians manage these non-motor aspects more effectively and improve patient outcomes.

Key Recommendations:

Autonomic Failure

• Bladder Dysfunction: Encourage behavioral modifications (e.g., timed fluid intake, bladder training) and, if necessary, consider antimuscarinics (e.g., solifenacin, trospium) or β3 agonists (e.g., mirabegron 50 mg once daily). Specifically, solifenacin 5 mg once daily, trospium 15–30 mg twice daily or darifenacin 7.5–15 mg once daily are preferred, due to their lower risk of cognitive side effects.
  • In patients who have responded inadequately to oral therapy, intravesical botulinum toxin A injection (200 U or customized) may be considered for treating severe urinary urge incontinence, if the individual motor and cognitive performance enables the subsequently likely necessary intermittent catheterization.
  • For nocturia, limit evening fluid intake and consider a 10°–20° head-up tilt in bed. In nocturnal polyuria, desmopressin (5–40 µg once daily nasal spray or 100–800 µg once daily per os) may be used with close monitoring of blood pressure, serum electrolytes and body weight.
• Orthostatic Hypotension (OH): Apply a four-step approach: (1) address aggravating factors (e.g., infections, dehydration); (2) review medications; (3) use non-pharmacological measures (increased fluid/salt intake if no contraindications, abdominal binders, head-up tilt sleeping); (4) add medications to raise blood pressure (e.g., midodrine 2.5–10 mg two to three times a day, fludrocortisone 0.1–0.3 µg once daily). For the diagnosis of OH, a Schellong test or tilt table examination should be performed.
  • Monitor for supine hypertension, which may require evening antihypertensives (e.g., low-dose losartan 25–100 mg or transdermal nitroglycerin 0.1–0.2 mg/h) and further adjustments. PD individuals with neurogenic OH should be screened for the presence of supine and nocturnal hypertension.
• Constipation: Follow the general German guideline on “Chronic Constipation.” Emphasize adequate hydration (1.5-2 L per day), fiber intake, and exercise.
  • First-line drug therapy is macrogol (polyethylene glycol, PEG, 13–26 g once daily). Consider bisacodyl (5–10 mg once daily), sodium picosulfate (5–10 mg once daily), or prucalopride (1–2 mg once daily) if needed.
• Male Erectile Dysfunction: First-line treatment involves phosphodiesterase type 5 (PDE-5) inhibitors (e.g., sildenafil 50–100 mg on demand), used cautiously in patients with orthostatic hypotension. A multidisciplinary approach with urologists is necessary.

Pain Management

• Classification: Differentiate PD-related pain (nociceptive, neuropathic, or nociplastic) from pain arising independently of PD. Use PD-specific scales, such as the King’s Parkinson’s Disease Pain Scale (KPPS) or the Parkinson’s Disease Pain Classification System (PD-PCS), to clarify pain etiology and guide therapy.
• Approach: Optimize dopaminergic therapy, especially if pain correlates with wearing-off.
  • Treat nociceptive pain per the WHO 3-step analgesic ladder (which recommends starting with non-opioid analgesics like acetaminophen or NSAIDs, then moving to mild opioids like codeine if needed, and finally to strong opioids like morphine for severe pain).
  • For neuropathic pain, preference is given to anticonvulsants (e.g., gabapentin 300–1800 mg, especially in case of concomitant restless legs syndrome) or antidepressants (e.g., duloxetine 60–120 mg, in case of concomitant depression).
  • Opioids (e.g., prolonged-release oxycodone/naloxone 5/2.5–20/10 mg, rarely up to 40/20 mg) may be considered in severe or refractory cases.

Sleep Disturbances

• Screening & Diagnosis: Use the Parkinson’s Disease Sleep Scale-2 (PDSS-2) to identify problems such as insomnia, nocturnal akinesia, restless legs, and REM sleep behavior disorder (RBD).
  • Objective tests—actigraphy, polygraphy, or video-polysomnography—are recommended for complex or treatment-refractory sleep issues.
• Treatment: Address comorbid conditions (e.g., restless legs syndrome, sleep apnea) following standard guidelines.
  • If motor fluctuations disturb sleep, adjust dopaminergic therapy (e.g., use long-acting levodopa or dopamine agonists at night).
  • RBD management typically includes creating a safe sleep environment and considering clonazepam (0.125–3 mg) or melatonin (2–9 mg).
  • Insomnia linked to circadian disruption may benefit from good sleep hygiene, bright light therapy, structured exercise, and (if indicated) low-dose agents such as eszopiclone (1 mg), doxepin (25 mg), zolpidem (5 mg), trazodone (50 mg), melatonin (2 mg), venlafaxine (37.5 mg, in case of comorbid depression), nortriptyline (25 mg) or mirtazapine (7.5 mg).
  • Excessive daytime sleepiness calls for an etiology-driven approach, with non-pharmacological strategies (e.g., scheduled naps, light therapy, exercise) and possible use of modafinil (200–400 mg) if needed. Driving should be reassessed if sleep attacks occur.

Clinical Impact: Poor sleep worsens cognitive decline, motor deficits, caregiver burden, and overall disease progression. RBD in early PD often predicts faster deterioration and earlier cognitive complications. The guideline also addresses the prognostic implications of sleep disturbances.

Conclusion: This guideline underscores the critical importance of identifying and managing non-motor symptoms in Parkinson’s disease. A structured, practice-oriented, etiology-driven stepwise approach to autonomic failure, pain, and sleep problems helps reduce the risk of dangerous complications, alleviates patient distress, and may delay the progression of both motor and cognitive domains. By integrating evidence-based recommendations into daily practice—focusing on precise assessment, tailored interventions, and regular follow-up—clinicians can improve outcomes and quality of life for individuals with PD and their caregivers.

Systemic Therapy for Stage I-III Anal Squamous Cell Carcinoma: Highlights of the ASCO Guideline

6 Jan, 2025 | 09:00h | UTC

Introduction:
This summary presents the key points of the American Society of Clinical Oncology (ASCO) guideline on systemic therapy for patients with stage I-III anal squamous cell carcinoma (SCC). The guideline’s objectives are to offer evidence-based recommendations that support clinicians in selecting radiosensitizing chemotherapy, dosage regimens, treatment strategies, the use of induction chemotherapy, and the use of ongoing adjuvant chemotherapy. This guidance focuses on optimizing chemoradiation (CRT) to improve oncologic outcomes while minimizing toxicities, particularly the myelosuppression that can limit therapy tolerability. Patients who are immunosuppressed and those with comorbidities receive special consideration.

Key Recommendations:

Radiosensitizing Chemotherapy

• Mitomycin-C (MMC) + Fluoropyrimidine: The standard radiosensitizing combination is MMC with fluorouracil (FU). Radiosensitizing means making the cancer cells more sensitive to radiation therapy. MMC with capecitabine (an oral alternative to FU) may also be offered, especially when infusion access is a concern. However, MMC is linked to higher hematologic toxicity, so its use demands vigilant monitoring.
• Cisplatin + FU: An alternative option for radiosensitization. This combination demonstrated noninferiority to MMC + FU in the ACT-II trial. The guideline states that the preferable regimen for patients with immunosuppression is cisplatin and FU, due to the myelosuppression associated with MMC. However, this regimen is not limited to this population. Cisplatin is unsuitable for individuals with renal impairment, significant neuropathy, or hearing loss, and there is no evidence supporting carboplatin substitution.

Dose and Schedule

• MMC + FU: Common regimens include MMC 10 mg/m^2 on days 1 and 29 (with caution on the second dose) or a single dose of 12 mg/m^2 on day 1, along with continuous-infusion FU (1,000 mg/m^2) on days 1–4 and 29–32. Clinicians should note that there is ongoing discussion about giving one versus two MMC doses, given the additional hematologic toxicity and radiation breaks often observed with two cycles.
• MMC + Capecitabine: MMC (single or divided dose as above) plus capecitabine (825 mg/m^2 orally twice daily on radiation days) is often used in practice, although large randomized trial data are lacking.
• Cisplatin + FU: Most commonly, cisplatin 60 mg/m^2 on days 1 and 29, with continuous-infusion FU (1,000 mg/m^2) on days 1–4 and 29–32, can be used. Weekly cisplatin regimens (20 mg/m^2 plus FU 300 mg/m^2) are another acceptable approach, though based on a lower level of evidence.

Single-Agent FU
For patients deemed unable to tolerate combination chemotherapy (e.g., poor performance status), single-agent FU with concurrent radiation may be offered.

Induction and Adjuvant Chemotherapy
No survival or disease-control benefit was observed with adding induction chemotherapy before CRT, nor with additional chemotherapy after CRT for localized anal cancer. Hence, routine use of induction or ongoing adjuvant therapy is not recommended.

Conclusion:
The guideline’s recommendations are based on moderate-quality evidence. These recommendations reinforce the longstanding role of MMC plus FU as the preferred radiosensitizing regimen for stage I-III anal SCC, with cisplatin-based or capecitabine-based options for specific patient needs. The guideline highlights that there are disparities in anal cancer incidence and outcomes, with higher rates among Black men and MSM. These disparities are further complicated by social determinants of health, such as smoking rates, HPV vaccination coverage, and access to screening and treatment. Limiting treatment toxicity—especially myelosuppression—remains critical to preserve treatment adherence and minimize breaks in radiation. Clinicians should tailor therapy to each patient’s comorbidities and performance status. Meanwhile, ongoing trials—such as ECOG-ACRIN 2165 (NCT03233711)—are investigating immunotherapy approaches for higher-risk locally advanced anal cancer, potentially informing future guideline updates.

AGA Clinical Practice Update on Managing Portal Vein Thrombosis in Cirrhotic Patients: Expert Review

3 Jan, 2025 | 10:00h | UTC

Introduction: This summary highlights key recommendations from an AGA expert review on portal vein thrombosis (PVT) in cirrhotic patients. PVT is common in cirrhosis, with an estimated five-year incidence of around 11%, and may worsen portal hypertension and elevate mortality. Management is challenging because of limited evidence, the potential complications of both PVT and anticoagulation, and significant heterogeneity regarding clot characteristics, host factors, and cirrhosis severity. This review presents the latest guidance on identifying clinically relevant PVT, selecting anticoagulation, and considering endovascular interventions, including TIPS (transjugular intrahepatic portosystemic shunt).

Key Recommendations:

1. No Routine Screening: Asymptomatic patients with compensated cirrhosis do not require regular screening for PVT in the absence of suggestive clinical changes.
2. Imaging Confirmation: When Doppler ultrasound reveals suspected PVT, contrast-enhanced CT or MRI is recommended to confirm the diagnosis, exclude malignancy, and characterize clot extent and occlusion.
3. Hypercoagulability Testing: Extensive thrombophilia workup is not indicated unless there is family or personal history of thrombotic events, or associated laboratory abnormalities.
4. Intestinal Ischemia Management: Patients who develop PVT with evidence of intestinal ischemia should receive prompt anticoagulation and, ideally, multidisciplinary team care involving gastroenterology, hepatology, interventional radiology, hematology, and surgery.
5. Observation of Minor or Recent Thrombi: In cirrhotic patients without ischemia, with recent (<6 months) thrombi that are <50% occlusive, close imaging follow-up every three months is a reasonable option to track potential spontaneous clot regression.
6. Anticoagulation for Significant PVT: Consider anticoagulation for more extensive or obstructive (>50%) recent PVT, especially if the main portal vein or mesenteric vessels are involved. Candidates for liver transplantation and those with inherited thrombophilia may derive additional benefit.
7. Chronic Cavernous PVT: Anticoagulation is generally not advised in patients with long-standing (>6 months) complete occlusion and well-formed collateral channels.
8. Variceal Screening: Perform endoscopic screening or ensure prophylaxis for varices. Avoid delays in initiating anticoagulation, as timeliness is essential for better recanalization outcomes.
9. Choice of Anticoagulant: Vitamin K antagonists, low-molecular-weight heparin, and direct oral anticoagulants (DOACs) are all viable options in cirrhosis. DOACs may be appropriate in well-compensated (Child-Turcotte-Pugh class A or certain class B) cirrhosis but should be avoided in class C. Treatment selection should consider patient preferences, monitoring feasibility, and risk of bleeding.
10. Duration of Therapy: Reassess clot status with cross-sectional imaging every three months. Continue anticoagulation for transplant-eligible individuals who show partial or complete recanalization, and consider discontinuation in nonresponders after six months if futility is evident.
11. TIPS Revascularization: Portal vein revascularization using TIPS may be pursued in patients who have other TIPS indications (like refractory ascites or variceal bleeding) or to improve transplant feasibility by recanalizing portal flow.

Conclusion: PVT in cirrhosis remains a complex clinical issue requiring careful evaluation of clot extent, timing, and the potential need for transplantation. The recommendations presented here underscore prompt imaging, timely anticoagulation for high-risk thrombi, and individualized therapy based on Child-Turcotte-Pugh classification and bleeding risk. When necessary, multidisciplinary collaboration is key to achieving optimal patient outcomes. Prospective randomized trials and standardized classifications of PVT will be instrumental in refining future guidelines.

Management of Adult Sepsis in Resource-Limited Settings: A Global Delphi-Based Consensus

26 Dec, 2024 | 02:06h | UTC

Introduction: This summary presents key points from a recent expert consensus on managing adult sepsis under limited-resource conditions, where patients may lack access to an ICU bed, advanced monitoring technologies, or sufficient staffing. The statements were developed through a Delphi process involving an international panel of clinicians, aiming to complement existing sepsis guidelines by focusing on pragmatic approaches and context-specific adaptations. These consensus statements address unique challenges such as limited diagnostic tests, alternative strategies for hemodynamic monitoring, and management of sepsis in areas with tropical infections.

Key Recommendations:

1. Location of Care and Transfer
   • When an ICU bed is unavailable, care can be provided in a non-ICU setting if minimum monitoring (neurological status, blood pressure, peripheral perfusion) is ensured.
   • Before transferring a patient, ensure airway patency, initiate intravenous fluids and antimicrobials, and maintain safe transport conditions.
   • Incorporate telemedicine or phone consultation with critical care specialists whenever feasible.
2. Diagnostic Considerations
   • Employ screening tools (e.g., qSOFA) in areas with limited resources, acknowledging its diagnostic constraints.
   • Use clinical parameters like altered mental state, capillary refill time (CRT), and urine output to gauge tissue perfusion when lactate measurement is unavailable.
   • Insert an indwelling urinary catheter in septic shock to monitor urine output accurately, balancing infection risks against close monitoring needs.
3. Hemodynamic Management
   • Rely on clinical indicators (CRT, urine output) to guide fluid resuscitation when serum lactate is not accessible.
   • Use fluid responsiveness tests (e.g., passive leg raising, pulse pressure variation) if advanced hemodynamic monitoring is impractical.
   • Consider balanced solutions such as Ringer’s lactate or Hartmann’s solution for fluid resuscitation.
   • Recognize that patients with tropical infections (e.g., malaria, dengue) may require cautious fluid volumes to avoid overload.
   • Initiate epinephrine if norepinephrine or vasopressin is unavailable, and use vasopressors through peripheral lines if central access cannot be established.
4. Antimicrobial Therapy
   • Administer antibiotics without delay (ideally within one hour) in suspected sepsis or septic shock.
   • In severe infections of parasitic origin (e.g., malaria), start antiparasitic agents promptly.
   • In settings where laboratory investigations are limited, begin broad-spectrum antimicrobial coverage when infection cannot be ruled out.
   • De-escalate or discontinue therapy based on clinical improvement, declining white blood cell counts, and adequate source control.
5. Respiratory Support
   • For acute hypoxemic respiratory failure in septic patients, noninvasive ventilation (NIV) can be used if high-flow nasal oxygen is not available, provided close monitoring for potential failure is ensured.

Conclusion: These consensus-based statements offer practical guidance for clinicians treating sepsis in resource-limited environments. By adapting globally accepted recommendations and incorporating alternative strategies—such as clinical markers of perfusion, use of peripheral vasopressors, and prioritizing immediate antimicrobial therapy—these principles aim to improve patient outcomes where healthcare resources are scarce. Further research and context-specific adaptations will be essential to address remaining uncertainties and refine these expert recommendations.

AGA Clinical Practice Update on Screening and Surveillance in High-Risk US Populations for Gastric Cancer: Expert Review

25 Dec, 2024 | 11:02h | UTC

Introduction:
This American Gastroenterological Association (AGA) Clinical Practice Update provides guidance on primary and secondary prevention strategies for gastric cancer (GC) among high-risk groups in the United States. GC disproportionately affects racial and ethnic minorities, certain first-generation immigrants from countries with elevated GC incidence, and individuals with specific hereditary syndromes or family histories of GC. Given ongoing disparities in diagnosis and outcomes, this document outlines best practices for recognizing at-risk individuals, performing high-quality endoscopic screening, and establishing surveillance protocols for gastric precancerous conditions.

Key Recommendations:

1. Identify High-Risk Groups: Consider screening among first-generation immigrants from high-incidence regions, people with a family history of GC in a first-degree relative, individuals with hereditary gastrointestinal syndromes, and patients with multiple risk factors (eg, chronic Helicobacter pylori infection, smoking, diets high in salt and processed meats).
2. Preferred Screening Modality: Upper endoscopy is considered the best method for detecting precancerous lesions (atrophic gastritis and intestinal metaplasia) and early malignancies. It allows direct visualization of the gastric mucosa, systematic biopsy, and accurate histologic staging.
3. High-Quality Endoscopic Examination: Essential elements include high-definition endoscopes, optimal mucosal cleansing and insufflation, adequate inspection time, systematic photodocumentation, and biopsy protocols (such as the updated Sydney System) to detect and characterize precancerous changes or early cancer.
4. H. pylori Eradication: Opportunistic screening for H. pylori and its eradication are key adjunctive measures in preventing GC development. Family-based testing—screening adult household members of H. pylori–positive individuals—may further reduce reinfection rates and disease progression.
5. Systematic Biopsy Protocols: When atrophic gastritis or intestinal metaplasia is suspected, obtain at least five biopsies (antrum/incisura and corpus in separate containers). Any suspicious lesion should be sampled independently.
6. Recognition of Metaplasia and Dysplasia: Endoscopists should be trained to accurately identify visual patterns associated with gastric intestinal metaplasia (GIM) and dysplasia. Artificial intelligence may hold promise, but current data are insufficient to recommend routine use.
7. Risk Stratification and Surveillance Intervals: Patients with confirmed GIM or dysplasia, especially those with severe or extensive metaplasia, may require follow-up endoscopy every three years. Individuals with multiple risk factors or severe metaplastic changes could benefit from shorter intervals.
8. Management of Dysplasia and Early GC: All dysplasia should be reviewed by an expert gastrointestinal pathologist. Visible high-grade dysplasia or early GC lesions generally warrant endoscopic submucosal dissection (ESD) at specialized centers to achieve en bloc, R0 resection and enable accurate pathology.
9. Post-Resection Surveillance: Individuals with successfully resected dysplasia or early cancer need ongoing endoscopic surveillance to detect metachronous lesions. Surveillance intervals vary depending on pathology results and patient-level factors.
10. De-Escalation of Screening: Discontinue screening or surveillance when the patient is no longer fit for potential endoscopic or surgical treatment.
11. Equity and Sustainability: To reduce GC mortality, it is crucial to address modifiable risk factors, enhance patient access to endoscopy and skilled practitioners, and integrate research advances, especially in noninvasive biomarker development and improved endoscopic technologies.

Conclusion:
An effective US-based GC screening and surveillance program requires robust preprocedural identification of high-risk individuals, intraprocedural adherence to quality endoscopy standards, and consistent postprocedural follow-up to ensure equitable access to treatment. By refining these clinical practices and prioritizing research, meaningful reductions in GC incidence and mortality can be achieved, ultimately improving patient outcomes and addressing healthcare disparities.

Guideline: Metformin to Prevent Antipsychotic-Induced Weight Gain

23 Dec, 2024 | 20:55h | UTC

Introduction:
This guideline was developed to address a pressing need for strategies to prevent antipsychotic-induced weight gain (AIWG), a frequent and troubling adverse effect of treatment in individuals with severe mental illness (SMI). Although metformin has shown consistent benefits in mitigating weight gain when initiated alongside antipsychotics, clinical uptake remains limited. The guideline follows the AGREE II framework and synthesizes both randomized and observational research, including Cochrane and meta-analytic data. The primary objective is to outline explicit indications, dosing approaches, and duration for using metformin to avert AIWG.

Key Recommendations:

1. Co-initiation With High-Risk Agents: In patients requiring higher-risk antipsychotics (olanzapine, clozapine), start metformin simultaneously. Evidence suggests that concurrent treatment may lessen weight gain by 3 to 5 kg in the early months, potentially yielding greater benefits over time.
2. Co-initiation With Medium-Risk Agents: For individuals prescribed quetiapine, paliperidone, or risperidone who have at least one cardiometabolic risk factor (such as diabetes, prediabetes, hypertension, or BMI above 25) or who are 10 to 25 years old, begin metformin at antipsychotic initiation to curb rapid weight changes.
3. Initiation During the First Year: If, at any point in the first year of antipsychotic treatment, weight gain exceeds 3% over baseline, consider adding metformin regardless of the antipsychotic being used.
4. Titration Schedule and Safety: The guideline advises starting at 500 mg once daily, then moving to 500 mg twice daily after about two weeks, with subsequent increases every two weeks up to 1 g twice daily (2 g/day) as tolerated. Metformin must be discontinued if lactic acidosis is suspected, if BMI falls below 20, or if the antipsychotic is stopped. Avoid its use in harmful alcohol consumption.
5. Additional Treatment Options: In cases of obesity (BMI ≥30) or comorbid metabolic disorders, clinicians should consider adding glucagon-like peptide-1 receptor agonists (GLP-1) where available. If cost, supply, or access is limited, metformin remains a practical alternative.

Conclusion:
This is the first evidence-based guideline focused on preventing AIWG by starting metformin at the time of antipsychotic initiation or upon early weight gain signs. By reducing the magnitude of weight increase, metformin may alleviate health risks tied to obesity, as well as psychological distress and nonadherence to treatment. Implementing the guideline involves continuous weight monitoring, structured dose adjustments, and shared decision-making. Ensuring clear communication about benefits and potential side effects will be crucial for sustaining adherence and improving patient outcomes.

2025 ASA Practice Advisory for the Perioperative Care of Older Adults Undergoing Inpatient Surgery

23 Dec, 2024 | 20:27h | UTC

Introduction: This summary outlines the American Society of Anesthesiologists (ASA) 2025 advisory on optimizing perioperative care for older adults (age 65 years or older) undergoing inpatient surgery. It focuses on preoperative, intraoperative, and postoperative measures to mitigate cognitive complications, especially delirium and longer-term cognitive decline, in a population that is highly vulnerable to functional deterioration and loss of independence. The recommendations are based on systematic reviews and meta-analyses, supplemented by expert consensus where evidence is limited. Although not intended as strict standards of care, these advisory statements provide practical guidance that can be adapted to local contexts and patient-specific needs.

Key Recommendations:

1. Expanded Preoperative Evaluation:
   • Incorporate frailty assessment, cognitive screening, and psychosocial or nutritional evaluations into routine preoperative workups for older patients.
   • Patients identified with frailty or cognitive deficits should receive targeted interventions, such as geriatric co-management, deprescribing when indicated, and early family education about delirium risks.
   • Evidence suggests a modest decrease in postoperative delirium when such evaluations are included.
2. Choice of Primary Anesthetic (Neuraxial vs. General):
   • Current studies do not demonstrate a clear advantage of neuraxial over general anesthesia in reducing postoperative delirium risk.
   • Both approaches are acceptable; individualize decisions based on patient factors, surgical requirements, and preference-sensitive discussions.
3. Maintenance of General Anesthesia (Total Intravenous vs. Inhaled Agents):
   • Data are inconclusive regarding delirium prevention, with no significant difference between total intravenous anesthesia (TIVA) and inhaled volatile agents.
   • Some low-level evidence indicates TIVA might reduce short-term cognitive decline, but this effect is inconsistent over longer follow-up.
4. Dexmedetomidine for Delirium Prophylaxis:
   • Moderate-level evidence supports dexmedetomidine for reducing delirium incidence in older patients, yet its use may increase bradycardia and hypotension.
   • Optimal dosing and timing remain uncertain, and baseline patient vulnerability should inform decisions.
5. Medications with Potential Central Nervous System Effects:
   • Drugs such as benzodiazepines, antipsychotics, anticholinergics, ketamine, and gabapentinoids warrant careful risk-benefit analysis.
   • Current findings are inconclusive, suggesting neither a firm endorsement nor outright disapproval; preexisting conditions and polypharmacy should guide individualized treatment plans.

Conclusion: Preserving cognitive function and independence in older adults undergoing inpatient surgery is a growing priority. These recommendations highlight the importance of comprehensive preoperative screenings (frailty, cognition, and psychosocial domains), shared decision-making when choosing anesthetic techniques, and thoughtful use of pharmacologic agents. While dexmedetomidine shows promise in mitigating delirium, vigilance regarding hypotension and bradycardia is essential. Ultimately, these strategies aim to reduce anesthesia-related complications in older patients by addressing the multifaceted determinants of postoperative cognitive outcomes.

Guideline: Doxycycline Postexposure Prophylaxis to Reduce Bacterial STI Incidence in High-Risk Populations

19 Dec, 2024 | 22:32h | UTC

Introduction: This summary presents key recommendations from the 2024 Centers for Disease Control and Prevention (CDC) guidelines on using doxycycline postexposure prophylaxis (doxyPEP) to prevent bacterial sexually transmitted infections (STIs), including syphilis, gonorrhea, and chlamydia. Targeting men who have sex with men (MSM) and transgender women with at least one bacterial STI in the past 12 months, these guidelines aim to reduce recurrence rates and improve sexual health outcomes through timely prophylactic intervention.

Key Recommendations:

1. Offer doxyPEP counseling to MSM and transgender women with a recent bacterial STI history, addressing the benefits, harms, and uncertainties of prophylactic doxycycline use.
2. Advise eligible patients to take a single 200 mg dose of doxycycline as soon as possible (ideally within 72 hours) following condomless oral, anal, or vaginal sexual exposure to reduce their subsequent STI risk.
3. Reinforce periodic screening (every 3–6 months) for STI markers, including syphilis and HIV serologies, as well as nucleic acid amplification tests for gonorrhea and chlamydia at relevant anatomical sites.
4. Integrate doxyPEP into comprehensive sexual health services that include risk-reduction counseling, condom use, recommended immunizations, and linkage to HIV preexposure prophylaxis (PrEP) or HIV care, thereby enhancing overall prevention strategies.
5. Consider extending doxyPEP to other high-risk groups, including heterosexual individuals with recurrent STIs, guided by clinical judgment and shared decision-making.
6. Monitor and address adverse events, particularly gastrointestinal symptoms, and acknowledge the potential for antimicrobial resistance. Continued vigilance is warranted given the risk of resistance in commensal flora and key STI pathogens, such as Neisseria gonorrhoeae.
7. Assess social and ethical dimensions of doxyPEP implementation, ensuring equitable access and minimizing potential harms, including stigma or intimate partner violence related to prophylaxis disclosure.

Conclusion: Implementing doxyPEP for MSM and transgender women who have experienced a recent bacterial STI can substantially lower the incidence of recurrent infections. By combining prophylactic doxycycline with routine surveillance, comprehensive preventive services, and careful consideration of resistance patterns, clinicians may enhance patient care and strengthen STI control efforts. Further investigation is needed to establish efficacy in cisgender women, transgender men, nonbinary persons, and other populations at risk. Longer-term, population-based studies focused on antimicrobial resistance and community-level effects will help guide sustainable and equitable use of this prevention strategy.

Guidelines for the Management of Hyperglycemic Crises in Adult Patients with Diabetes

15 Dec, 2024 | 13:18h | UTC

Introduction: Diabetic ketoacidosis (DKA) and hyperglycemic hyperosmolar state (HHS) are critical, acute complications of type 1 and type 2 diabetes. Recent data show a global rise in DKA and HHS admissions, driven by factors such as psychosocial challenges, suboptimal insulin use, infection, and certain medications (e.g., SGLT2 inhibitors). This consensus report, developed by leading diabetes organizations (ADA, EASD, JBDS, AACE, DTS), provides updated recommendations on epidemiology, pathophysiology, diagnosis, treatment, and prevention of DKA and HHS in adults, aiming to guide clinical practice and improve outcomes.

Key Recommendations:

1. Diagnosis and Classification:
   • DKA is defined by hyperglycemia (>11.1 mmol/l [200 mg/dl] or known diabetes), elevated ketone levels (β-hydroxybutyrate ≥3.0 mmol/l), and metabolic acidosis (pH <7.3 or bicarbonate <18 mmol/l).
   • HHS is characterized by marked hyperglycemia, severe hyperosmolality (>320 mOsm/kg), significant dehydration, and minimal ketonaemia or acidosis.
   • Consider euglycemic DKA, especially with SGLT2 inhibitor use.
   • Classify DKA severity (mild, moderate, severe) to guide the setting of care.
2. Fluid and Electrolyte Management:
   • Initiate isotonic or balanced crystalloid solutions to restore intravascular volume, enhance renal perfusion, and reduce hyperglycemia.
   • Adjust fluids based on hydration, sodium levels, and glucose trends.
   • Add dextrose when glucose falls below ~13.9 mmol/l (250 mg/dl) to allow ongoing insulin therapy until ketoacidosis resolves.
   • Carefully monitor potassium and provide adequate replacement to prevent severe hypokalemia.
3. Insulin Therapy:
   • Start a continuous intravenous infusion of short-acting insulin as soon as feasible after confirming adequate potassium.
   • For mild or moderate DKA, subcutaneous rapid-acting insulin analogs may be used under close supervision.
   • Continue insulin until DKA resolves (pH ≥7.3, bicarbonate ≥18 mmol/l, β-hydroxybutyrate <0.6 mmol/l) or HHS improves (osmolality <300 mOsm/kg, improved mental status).
   • Overlap subcutaneous basal insulin by 1–2 hours before discontinuing intravenous insulin to prevent rebound hyperglycemia.
4. Additional Considerations:
   • Avoid routine bicarbonate; use only if pH <7.0.
   • Phosphate supplementation is not routinely recommended unless levels are severely low.
   • Identify and treat underlying precipitating causes (infection, psychological factors, medication-related triggers).
   • Address social determinants of health and mental health conditions to reduce recurrence.

Conclusion: By implementing these evidence-based recommendations—early diagnosis, structured fluid and insulin therapy, careful electrolyte management, and addressing precipitating factors—clinicians can improve patient care, reduce morbidity and mortality, and enhance the quality of life for adults experiencing DKA and HHS.

Management of Adult Sepsis in Resource-Limited Settings: A Global Delphi-Based Consensus

24 Dec, 2024 | 13:35h | UTC

Introduction: This summary presents key points from a recent expert consensus on managing adult sepsis under limited-resource conditions, where patients may lack access to an ICU bed, advanced monitoring technologies, or sufficient staffing. The statements were developed through a Delphi process involving an international panel of clinicians, aiming to complement existing sepsis guidelines by focusing on pragmatic approaches and context-specific adaptations. These consensus statements address unique challenges such as limited diagnostic tests, alternative strategies for hemodynamic monitoring, and management of sepsis in areas with tropical infections.

Key Recommendations:

1. Location of Care and Transfer
   • When an ICU bed is unavailable, care can be provided in a non-ICU setting if minimum monitoring (neurological status, blood pressure, peripheral perfusion) is ensured.
   • Before transferring a patient, ensure airway patency, initiate intravenous fluids and antimicrobials, and maintain safe transport conditions.
   • Incorporate telemedicine or phone consultation with critical care specialists whenever feasible.
2. Diagnostic Considerations
   • Employ screening tools (e.g., qSOFA) in areas with limited resources, acknowledging its diagnostic constraints.
   • Use clinical parameters like altered mental state, capillary refill time (CRT), and urine output to gauge tissue perfusion when lactate measurement is unavailable.
   • Insert an indwelling urinary catheter in septic shock to monitor urine output accurately, balancing infection risks against close monitoring needs.
3. Hemodynamic Management
   • Rely on clinical indicators (CRT, urine output) to guide fluid resuscitation when serum lactate is not accessible.
   • Use fluid responsiveness tests (e.g., passive leg raising, pulse pressure variation) if advanced hemodynamic monitoring is impractical.
   • Consider balanced solutions such as Ringer’s lactate or Hartmann’s solution for fluid resuscitation.
   • Recognize that patients with tropical infections (e.g., malaria, dengue) may require cautious fluid volumes to avoid overload.
   • Initiate epinephrine if norepinephrine or vasopressin is unavailable, and use vasopressors through peripheral lines if central access cannot be established.
4. Antimicrobial Therapy
   • Administer antibiotics without delay (ideally within one hour) in suspected sepsis or septic shock.
   • In severe infections of parasitic origin (e.g., malaria), start antiparasitic agents promptly.
   • In settings where laboratory investigations are limited, begin broad-spectrum antimicrobial coverage when infection cannot be ruled out.
   • De-escalate or discontinue therapy based on clinical improvement, declining white blood cell counts, and adequate source control.
5. Respiratory Support
   • For acute hypoxemic respiratory failure in septic patients, noninvasive ventilation (NIV) can be used if high-flow nasal oxygen is not available, provided close monitoring for potential failure is ensured.

Conclusion: These consensus-based statements offer practical guidance for clinicians treating sepsis in resource-limited environments. By adapting globally accepted recommendations and incorporating alternative strategies—such as clinical markers of perfusion, use of peripheral vasopressors, and prioritizing immediate antimicrobial therapy—these principles aim to improve patient outcomes where healthcare resources are scarce. Further research and context-specific adaptations will be essential to address remaining uncertainties and refine these expert recommendations.

Consensus Guideline: Low-Dose Oral Minoxidil for Hair Loss Management

24 Nov, 2024 | 20:27h | UTC

Introduction: Hair loss significantly affects patients’ quality of life, encompassing conditions like androgenetic alopecia, alopecia areata, and telogen effluvium. While topical minoxidil is FDA-approved for certain hair loss types, limitations have led to increased off-label use of low-dose oral minoxidil (LDOM). Recognizing the need for standardized guidance, an international panel of 43 dermatologists from 12 countries developed a consensus statement using a modified Delphi process to inform best practices for prescribing LDOM until more robust evidence emerges.

Key Recommendations:

1. Patient Selection:
   • Indications: LDOM may benefit adults and adolescents with androgenetic alopecia, age-related thinning, alopecia areata, telogen effluvium, traction alopecia, persistent chemotherapy-induced alopecia, and endocrine therapy–induced alopecia.
   • Contraindications: LDOM is contraindicated in patients with hypersensitivity to minoxidil, significant drug interactions, history of pericardial effusion or tamponade, pericarditis, congestive heart failure, pulmonary hypertension with mitral stenosis, pheochromocytoma, and during pregnancy or breastfeeding.
   • Precautions: Use cautiously in patients with tachycardia, arrhythmias, hypotension (blood pressure <90/60 mm Hg), impaired kidney function, or those undergoing dialysis.
2. Dosing Guidelines:
   • Adults:
     • Females: Starting dose of 1.25 mg daily; dosing range 0.625 mg to 5 mg daily.
     • Males: Starting dose of 2.5 mg daily; dosing range 1.25 mg to 5 mg daily.
   • Adolescents (12–17 years):
     • Females: Starting dose of 0.625 mg daily; dosing range 0.625 mg to 2.5 mg daily.
     • Males: Starting dose of 1.25 mg daily; dosing range 1.25 mg to 5 mg daily.
   • Considerations: Dosing influenced by sex, age, risk of systemic adverse effects, and desire to minimize hypertrichosis.
3. Monitoring and Evaluation:
   • Baseline Assessments: Routine labs and ECGs are not required unless precautions are present; consult specialists if needed.
   • Adverse Effects Monitoring: Counsel patients on potential side effects like hypertrichosis, dizziness, tachycardia, and fluid retention; monitor for signs such as swelling or weight gain.
   • Efficacy Expectations: Initial effects may be observed at three months; efficacy may take up to six months if transient shedding occurs.
4. Adjunctive Therapies:
   • Spironolactone: May be co-administered in female patients with hirsutism, acne, or polycystic ovary syndrome to enhance treatment efficacy and manage fluid retention.
   • Beta-Blockers: Consider in consultation with specialists, especially for managing tachycardia.
5. Preference Over Topical Minoxidil:
   • LDOM may be preferred when topical minoxidil causes scalp irritation, is cosmetically unacceptable, ineffective, or when enhanced hypertrichosis is desired.

Conclusion: This consensus provides a structured approach for clinicians considering LDOM as an off-label treatment for hair loss. By outlining patient selection, dosing, monitoring, and when to seek specialist input, these recommendations aim to optimize patient outcomes and safety.

Review: Comparative Analysis of ESC and ESH Hypertension Guidelines

20 Nov, 2024 | 15:03h | UTC

Introduction: Hypertension remains a significant global health challenge with increasing prevalence and substantial morbidity and mortality rates. To address this, the European Society of Cardiology (ESC) and the European Society of Hypertension (ESH) have independently published updated guidelines on hypertension management. This review provides a pragmatic comparison of these guidelines, highlighting their major similarities and differences to assist clinicians in optimizing patient care.

Key Recommendations:

Shared Recommendations:

1. Diagnosis Criteria: Both guidelines recommend diagnosing hypertension based on office systolic and diastolic blood pressures of ≥140/90 mmHg.
2. Blood Pressure Targets: Both advocate aiming for an optimal blood pressure of <130/80 mmHg. The ESH emphasizes personalized targets for specific populations like the elderly, while the ESC adopts the ALARA (as low as reasonably achievable) principle.
3. Out-of-Office Measurements: Emphasis is placed on home blood pressure monitoring and ambulatory measurements to confirm diagnoses and tailor treatments.
4. Comprehensive Assessment: Both recommend thorough initial evaluations, including screening for orthostatic hypotension, comorbidities, and hypertension-mediated organ damage (HMOD).
5. Early Treatment Initiation: Both suggest starting antihypertensive therapy promptly, preferably using a single-pill combination of two agents after lifestyle interventions.
6. Treatment Goals and Follow-Up: Both aim for patients to reach blood pressure targets within three months, underscoring the importance of close monitoring.
7. Adjunctive Therapies: The use of SGLT-2 inhibitors is recommended for patients with chronic kidney disease and/or heart failure. Renal denervation is considered for true resistant hypertension.

Differences:

1. Blood Pressure Classification: The ESC introduces a new category of “elevated blood pressure,” altering patient classification but with minimal impact on practical management.
2. Screening for Secondary Hypertension: The ESC strongly encourages screening for secondary hypertension, particularly primary aldosteronism; the ESH does not emphasize this as strongly.
3. Age Stratification: Different age thresholds for the very elderly are used (ESH: ≥80 years; ESC: ≥85 years), with the ESH providing more detailed treatment personalization for this group.
4. Treatment Targets Philosophy: The ESC supports the ALARA principle for blood pressure targets, aiming for the lowest achievable levels without adverse effects, while the ESH provides specific target ranges.
5. Beta-Blocker Use: The ESH includes beta-blockers as first-line therapy options, whereas the ESC positions them as third-line agents.

Conclusion: Despite minor discrepancies, the ESC and ESH hypertension guidelines are largely concordant and based on the same evidence base. Both sets provide clear, pragmatic recommendations emphasizing early diagnosis, personalized treatment, and close follow-up. Clinicians can confidently use either guideline to inform practice, as both aim to improve patient outcomes by effectively managing hypertension in the primary care setting.

Guideline: Management of Urinary Tract Infections in Pediatrics and Adults

5 Nov, 2024 | 18:59h | UTC

Introduction: Urinary tract infections (UTIs) are among the most common infections worldwide, significantly impacting patient quality of life and imposing substantial clinical and economic burdens. Despite advancements in diagnosis and treatment, UTIs continue to cause high morbidity and mortality, ranging from simple cystitis to life-threatening sepsis. Addressing the discrepancy between evidence quality and recommendation strength in existing guidelines, the WikiGuidelines Group has developed a consensus statement. This guideline aims to provide evidence-based recommendations for the prevention, diagnosis, and management of UTIs across diverse clinical settings.

Key Recommendations:

1. Cranberry Products:
   • Recommendation: Cranberry juice or supplements are recommended for preventing symptomatic, culture-verified UTIs in women with recurrent UTIs, children, and individuals susceptible after interventions.
   • Quality of Evidence: Moderate
   • Recommendation Strength: Strong
2. Methenamine Hippurate:
   • Recommendation: Methenamine hippurate is recommended as an alternative to prophylactic antibiotics for preventing recurrent UTIs in patients with intact bladder anatomy.
   • Quality of Evidence: Moderate
   • Recommendation Strength: Strong
3. Topical Estrogen:
   • Recommendation: Vaginal estrogen therapy is recommended for postmenopausal women to reduce recurrent UTIs by restoring the vaginal microbiome.
   • Quality of Evidence: High
   • Recommendation Strength: Strong
4. Empirical Treatment Regimens:
   • Recommendation: For uncomplicated cystitis, nitrofurantoin is recommended as a first-line agent. For pyelonephritis, trimethoprim/sulfamethoxazole or a first-generation cephalosporin are reasonable first-line agents, depending on local resistance rates.
   • Quality of Evidence: Moderate
   • Recommendation Strength: Strong
5. Treatment Duration for Acute Cystitis in Adults:
   • Recommendation:
     • Nitrofurantoin: 5 days
     • Trimethoprim/sulfamethoxazole: 3 days
     • Oral fosfomycin: Single dose
   • Quality of Evidence: High
   • Recommendation Strength: Strong
6. Treatment Duration for Acute Pyelonephritis in Adults:
   • Recommendation:
     • Fluoroquinolones: 5–7 days
     • Dose-optimized β-lactams: 7 days
   • Quality of Evidence: High
   • Recommendation Strength: Strong
7. Antimicrobial Stewardship:
   • Recommendation: De-escalation of antibiotics and the use of mostly or all oral treatment regimens are recommended to optimize antimicrobial use and reduce adverse effects.
   • Quality of Evidence: High
   • Recommendation Strength: Strong

Conclusion: The consensus highlights a significant lack of high-quality prospective data in many areas related to UTIs, limiting the ability to provide clear recommendations. Implementing these evidence-based guidelines can enhance patient care by promoting effective prevention strategies, accurate diagnosis based on clinical symptoms, appropriate treatment durations, and robust antimicrobial stewardship. This approach is expected to improve clinical outcomes, reduce antimicrobial resistance, and preserve the effectiveness of current treatments.
