Cohort Study: Long-Term Multivitamin Use Not Linked to Reduced Mortality in Over 390,000 US Adults
18 Aug, 2024 | 15:07h | UTCtudy Design and Population: This cohort study examined the association between daily multivitamin (MV) use and mortality risk using data from three large prospective cohorts in the United States. The study included 390,124 generally healthy adults with no prior history of cancer or major chronic diseases. Participants were followed for up to 27 years, with baseline MV use assessed between 1993 and 2001 and follow-up assessments from 1998 to 2004.
Main Findings: Daily MV use was not associated with a reduction in all-cause mortality. In fact, the study found a 4% higher risk of mortality among daily MV users compared to nonusers during the first half of the follow-up period (HR, 1.04; 95% CI, 1.02-1.07), although this risk was not significant in the second half. The findings were consistent across major causes of death, including heart disease, cancer, and cerebrovascular diseases.
Implications for Practice: These findings suggest that long-term MV use does not confer a mortality benefit among generally healthy adults. Healthcare providers may need to reconsider recommending MVs for longevity purposes, as the evidence does not support their efficacy in reducing mortality risk.
Updated Guidelines on Perioperative Management of Anticoagulant and Antiplatelet Therapy for Interventional Techniques – Pain Physician
18 Aug, 2024 | 14:52h | UTCIntroduction: The American Society of Interventional Pain Physicians (ASIPP) has published updated guidelines for the perioperative management of patients undergoing interventional techniques while receiving antiplatelet and anticoagulant therapy. These guidelines are essential for clinicians to balance the risk of thromboembolism against the risk of bleeding during interventional procedures.
Key Points:
1 – Risk of Thromboembolic Events:
– Thromboembolic events have a higher risk of morbidity and mortality compared to the risk of epidural hematoma. Thus, interruption of antithrombotic therapy should be carefully considered.
2 – Risk Stratification of Procedures:
– Interventional techniques are classified into three categories based on risk: low, moderate, or high. For high-risk procedures, cessation of anticoagulant or antiplatelet therapy is recommended, whereas for low to moderate-risk procedures, therapy may continue under certain conditions.
3 – Management of Direct Oral Anticoagulants (DOACs):
– DOACs such as dabigatran, apixaban, rivaroxaban, and edoxaban should generally be discontinued for 2 days before high-risk procedures and one day for moderate-risk procedures. Adjustments are needed based on renal function, specially for dabigatran.
4 – Discontinuation of Aspirin:
– For high-risk interventional procedures, discontinuation of aspirin (81 or 325 mg) is recommended 6 days before the procedure. However, for low to moderate-risk procedures, aspirin therapy may be continued or stopped for 3 days depending on individual risk factors and clinical judgment.
5 – Discontinuation of Other Antiplatelet Agents:
– Clopidogrel (Plavix) and Prasugrel (Effient): These agents should be discontinued 6 days before high-risk procedures. For low-risk procedures, these medications can be continued.
– Ticagrelor (Brilinta): Discontinue for 5 days before high-risk procedures, with consideration of patient-specific risk factors.
6 – Timing for Restarting Therapy:
– Antithrombotic therapy should typically be resumed within 12-24 hours after low to moderate-risk procedures and within 24-48 hours after high-risk procedures, depending on bleeding risk and patient status.
7 – Shared Decision-Making:
– Decisions on whether to continue or discontinue antithrombotic therapy should involve shared decision-making between the patient, the interventional pain specialist, and other treating physicians, considering all associated risks.
Conclusion: These guidelines provide a comprehensive framework for managing the delicate balance between thromboembolic and bleeding risks in patients on anticoagulant or antiplatelet therapy undergoing interventional procedures. They emphasize the importance of personalized care and multidisciplinary collaboration.
Meta-Analysis: Effects of Psychological, Psychosocial, Pharmacological, Physical and Combined Treatments for Adults with a New Episode of Depression – eClinicalMedicine
17 Aug, 2024 | 19:49h | UTCStudy Design and Population: This systematic review and network meta-analysis examined 676 randomized controlled trials (RCTs) involving 105,477 participants, comparing psychological, psychosocial, pharmacological, physical, and combined treatments for adults with a new episode of unipolar depression. The study stratified interventions based on depressive symptom severity (less severe and more severe).
Main Findings: For less severe depression, group cognitive behavioral therapy (CBT) was the only treatment class that significantly improved depressive symptoms compared to treatment as usual (TAU). For more severe depression, effective interventions included combined individual CBT with antidepressants, individual behavioral therapies, and combined treatments like acupuncture or exercise with antidepressants. Notably, antidepressants alone did not show significant effects in less severe depression.
Implications for Practice: These findings suggest that group CBT may be an effective first-line treatment for less severe depression, while combined therapies, particularly those involving antidepressants and individual psychological interventions, are more effective in treating more severe depression. This evidence could guide clinical decision-making and inform updates to treatment guidelines.
Study Shows High Prevalence of Solid Lung Nodules in Nonsmoking Adults – Radiology
14 Aug, 2024 | 13:14h | UTCStudy Design and Population: This cohort study examined the prevalence and size distribution of solid lung nodules in a nonsmoking population from the Northern Netherlands. A total of 10,431 participants aged 45 years and older, predominantly nonsmokers, were included in the Imaging in Lifelines (ImaLife) study. The study utilized low-dose chest CT scans to detect and measure lung nodules.
Main Findings: Lung nodules were present in 42% of participants, with a higher prevalence in males (47.5%) than females (37.7%). The prevalence of clinically relevant nodules (≥100 mm³) was 11.1%, and actionable nodules (≥300 mm³) were found in 2.3% of individuals. Both prevalence and nodule size increased with age, and male participants consistently showed a higher prevalence and larger nodule sizes compared to females.
Implications for Practice: While 42% of nonsmoking adults in this Northern European cohort were found to have solid lung nodules, the incidence of lung cancer within this population is notably low. This suggests that many of the clinically relevant and even actionable nodules identified in nonsmokers are likely benign. These findings highlight the need to refine nodule management strategies for individuals at low risk of lung cancer, potentially reducing unnecessary follow-up and interventions in nonsmoking populations. Future research on lung cancer outcomes in this cohort could further inform and optimize guidelines for nodule management in low-risk groups.
2024 ACC Expert Consensus Decision Pathway on Clinical Assessment, Management, and Trajectory of Patients Hospitalized With Heart Failure – J Am Coll Cardiol
14 Aug, 2024 | 12:47h | UTCIntroduction: The American College of Cardiology (ACC) has released a focused update on the 2019 Expert Consensus Decision Pathway (ECDP) for the management of patients hospitalized with heart failure (HF). This update reflects new evidence and aligns with the latest ACC/AHA/HFSA heart failure guidelines.
Key Points:
1 – SGLT Inhibitors in Hospitalization:
– The update emphasizes the use of sodium-glucose cotransporter 2 (SGLT2) inhibitors during hospitalization for heart failure, regardless of left ventricular ejection fraction (LVEF). These medications should be initiated early, provided the patient is hemodynamically stable and there are no contraindications such as type 1 diabetes or severe kidney dysfunction.
2 – Triage and Admission Criteria:
– Patients with a new diagnosis of HF with rapidly progressing symptoms, severe congestion, or higher disease complexity should generally be admitted from the emergency department (ED). Some low-risk patients may be managed in an observation unit or via Hospital at Home (HaH) programs.
3 – Daily Trajectory Review:
– The clinical trajectory of hospitalized HF patients should be reviewed daily to monitor for effective decongestion and the need for initiation of guideline-directed neurohormonal therapies. Adjustments should be made based on patient response.
4 – Neurohormonal Therapy Optimization:
– Strategies for optimizing neurohormonal therapies, including beta-blockers, angiotensin receptor/neprilysin inhibitors (ARNIs)/angiotensin-converting enzyme (ACE) inhibitors/angiotensin receptor blockers (ARBs), and mineralocorticoid antagonists (MRAs), are updated. Therapy should be personalized based on patient tolerance, hemodynamics, and kidney function.
5 – Decongestion Strategies:
– The update provides enhanced guidance on diuretic therapy, including the use of dual nephron blockade and carbonic anhydrase inhibitors like acetazolamide for patients not responding adequately to loop diuretics.
6 – Palliative Care Integration:
– The role of palliative care has been highlighted, particularly for patients with worsening HF or those not responding to standard treatments. Early referral to palliative care can improve advance directive completion rates and reduce readmissions.
7 – Discharge and Follow-Up:
– Detailed discharge planning is crucial, including providing patients and caregivers with comprehensive information on medications, follow-up appointments, and the importance of adhering to the prescribed regimen. Telehealth may be utilized for post-discharge follow-up.
Conclusion: This focused update to the ACC ECDP provides essential guidance for the clinical management of patients hospitalized with heart failure. It emphasizes the early initiation of SGLT inhibitors, careful daily trajectory reviews, optimization of neurohormonal therapies, and the integration of palliative care. These updates aim to improve patient outcomes by addressing both short-term and long-term management strategies.

IDSA 2024 Guidelines for Treatment of Antimicrobial-Resistant Gram-Negative Infections – Clin Infect Dis
10 Aug, 2024 | 20:16h | UTCIntroduction:
The Infectious Diseases Society of America (IDSA) has released updated guidelines in 2024 addressing the treatment of infections caused by antimicrobial-resistant (AMR) Gram-negative bacteria. These guidelines cover pathogens including extended-spectrum β-lactamase-producing Enterobacterales (ESBL-E), AmpC β-lactamase-producing Enterobacterales (AmpC-E), carbapenem-resistant Enterobacterales (CRE), difficult-to-treat Pseudomonas aeruginosa (DTR P. aeruginosa), carbapenem-resistant Acinetobacter baumannii (CRAB), and Stenotrophomonas maltophilia.
Key Points:
1 – ESBL-E Infections:
– Preferred treatment for uncomplicated cystitis includes nitrofurantoin and TMP-SMX. Fluoroquinolones and carbapenems are alternatives but should be reserved to prevent resistance.
– For pyelonephritis or complicated urinary tract infections (cUTI), TMP-SMX, ciprofloxacin, or levofloxacin are preferred. Carbapenems are recommended when resistance precludes other options.
2 – AmpC-E Infections:
– Cefepime is suggested for treating infections caused by organisms at moderate risk of significant AmpC production (e.g., Enterobacter cloacae complex, Klebsiella aerogenes, and Citrobacter freundii).
– The use of cephamycins (e.g., cefoxitin, cefotetan) for treating ESBL-E infections is not recommended due to insufficient clinical outcome data.
3 – CRE Infections:
– Acknowledgement of increased prevalence of metallo-beta-lactamase (MBL)-producing CRE in the U.S.
– The combination of ceftazidime-avibactam and aztreonam is suggested for MBL-producing CRE, with updated dosing recommendations provided.
4 – DTR Pseudomonas aeruginosa:
– Traditional β-lactams (e.g., cefepime) with high-dose extended-infusion therapy are recommended.
– Tobramycin or amikacin, administered once daily, are alternatives for pyelonephritis or cUTI.
5 – CRAB and Stenotrophomonas maltophilia Infections:
– Sulbactam-durlobactam with meropenem or imipenem-cilastatin is the preferred treatment for CRAB.
– The order of preference for agents treating S. maltophilia includes cefiderocol, ceftazidime-avibactam, and aztreonam, among others.
Conclusion:
The 2024 IDSA guidelines provide critical updates on managing AMR Gram-negative infections, emphasizing the importance of selecting the appropriate antibiotic based on susceptibility, resistance mechanisms, and patient-specific factors. These guidelines are essential for optimizing treatment outcomes in the face of increasing antimicrobial resistance.

New Guidelines Recommend Against Routine Vitamin D Testing and Treatment for Healthy Adults – J Clin Endocrinol Metab
4 Aug, 2024 | 19:19h | UTCIntroduction: The Endocrine Society has developed new clinical practice guidelines focused on the use of vitamin D for the prevention of various diseases. These guidelines were created by a multidisciplinary panel, including experts in adult and pediatric endocrinology, internal medicine, obstetrics and gynecology, nutrition, and epidemiology.
Key Points:
1 – Empiric Vitamin D Supplementation in Children and Adolescents:
– Recommended to prevent nutritional rickets.
– May lower the risk of respiratory tract infections.
– Dosage in trials ranged from 300 to 2000 IU daily, with an average of about 1200 IU per day.
2 – Empiric Vitamin D Supplementation or Testing in Adults Under 75:
– Not recommended for generally healthy adults without specific indications.
3 – Empiric Vitamin D Supplementation in Adults Over 75:
– Suggested due to its potential to lower the risk of mortality.
– Treatment should be empirical, no testing recommended if there are no established indications for testing (e.g., hypocalcemia).
– Recommended daily rather than intermittent high doses. Dosage in clinical trials ranged from 400 to 3333 IU daily equivalent.
4 – Vitamin D Supplementation During Pregnancy:
– Suggested to lower the risk of preeclampsia, intrauterine mortality, preterm birth, small-for-gestational-age birth, and neonatal mortality.
– Empiric supplementation recommended without routine 25(OH)D testing unless there are established indications for testing.
– Dosages in trials ranged from 600 to 5000 IU daily equivalent, with an average of about 2500 IU per day.
5 – Vitamin D and High-Risk Prediabetes:
– Suggested to reduce the progression to diabetes.
– In clinical trials, vitamin D dosages ranged from 842 to 7543 IU daily. The estimated weighted average was approximately 3500 IU per day.
6 – Routine 25(OH)D Testing:
– Not recommended for the general population, including those with obesity or dark complexion.
– No clear evidence defining optimal target levels for disease prevention.
Conclusion: These guidelines emphasize the importance of targeted vitamin D supplementation for specific age groups and conditions, while advising against routine testing for vitamin D levels in the general population. Empiric supplementation is considered beneficial, particularly in children, pregnant women, and older adults, and is feasible, cost-effective, and generally acceptable.
RCT: Pantoprazole Reduces GI Bleeding in Mechanically Ventilated ICU Patients – N Engl J Med
3 Aug, 2024 | 18:57h | UTCStudy Design and Population: This international, randomized, double-blind trial involved 4,821 critically ill adults undergoing invasive mechanical ventilation across 68 intensive care units (ICUs). Participants were assigned to receive either intravenous pantoprazole (40 mg daily) or a matching placebo. The primary efficacy outcome was the incidence of clinically significant upper gastrointestinal bleeding within 90 days, and the primary safety outcome was mortality from any cause within the same period.
Main Findings: The trial found that upper gastrointestinal bleeding occurred in 1.0% of patients treated with pantoprazole compared to 3.5% in the placebo group (hazard ratio, 0.30; 95% CI, 0.19 to 0.47; P<0.001). Mortality at 90 days was 29.1% in the pantoprazole group and 30.9% in the placebo group, showing no significant difference (hazard ratio, 0.94; 95% CI, 0.85 to 1.04; P=0.25). There were no significant differences in the rates of ventilator-associated pneumonia or Clostridioides difficile infection between the groups.
Implications for Practice: The study demonstrates that pantoprazole significantly reduces the risk of upper gastrointestinal bleeding in critically ill patients on mechanical ventilation without affecting overall mortality. This suggests that pantoprazole can be considered a safe and effective option for stress ulcer prophylaxis in this high-risk population, potentially improving patient outcomes in the ICU.
Cohort Study: Thick liquids not linked to better outcomes in hospitalized patients with dementia—further studies required – JAMA Intern Med
25 May, 2024 | 19:41h | UTC– This matched cohort study evaluated the impact of thick vs. thin liquids on clinical outcomes in 8916 hospitalized patients aged 65 and older with Alzheimer Disease and Related Dementias (ADRD) and oropharyngeal dysphagia. Conducted across 11 diverse hospitals in New York from January 2017 to September 2022, the study utilized propensity score matching to ensure comparability between the two diet groups based on demographic and clinical characteristics.
– The study found no significant difference in mortality rates between the thick and thin liquid groups (hazard ratio, 0.92; 95% CI, 0.75-1.14; P = .46). Patients on a thick liquid diet were less likely to require intubation (odds ratio [OR], 0.66; 95% CI, 0.54-0.80) but exhibited a higher incidence of respiratory complications such as pneumonia (OR, 1.73; 95% CI, 1.56-1.91).
– The findings suggest that while thick liquids may reduce the need for intubation, they may increase the risk of respiratory complications. These results underscore the necessity for future prospective studies to more definitively ascertain the effectiveness of thick liquids in improving clinical outcomes for this patient population.

Cohort Study: Efficacy of first-line color doppler ultrasound in diagnosing giant cell arteritis – Ann Intern Med
25 May, 2024 | 19:39h | UTCThis prospective multicenter study aimed to evaluate the efficacy of using color Doppler ultrasound of the temporal arteries as the first-line diagnostic tool for Giant Cell Arteritis (GCA) in 165 elderly patients with high clinical suspicion of the disease. The study followed participants over two years, comparing ultrasound results with temporal artery biopsy (TAB) and physician-based clinical diagnosis including other imaging tests. Key findings indicate that ultrasound confirmed GCA in 44% of cases, which was higher compared to TAB (17%) and clinical expertise (21%). The study showed that using ultrasound first can avoid the need for further invasive tests like TAB in patients with positive ultrasound results. The limitations of the study include its small sample size, unblinded test results, and the absence of a universally accepted objective diagnostic standard. However, it highlights the potential of ultrasound in the early and non-invasive diagnosis of GCA, potentially reducing the risk of severe complications by expediting treatment initiation.

RCT: Triple combination of paracetamol, ibuprofen, and dexamethasone reduces morphine use post-hip arthroplasty – Lancet Rheumatol
11 May, 2024 | 14:18h | UTCStudy Design and Population: The RECIPE trial was a randomized, blinded, placebo-controlled multicenter study conducted across nine Danish hospitals to evaluate the effectiveness of non-opioid analgesic combinations in managing postoperative pain following total hip arthroplasty. A total of 1,060 adults scheduled for surgery were enrolled and randomly assigned to one of four treatment groups, receiving combinations of paracetamol, ibuprofen, and dexamethasone. The study’s primary endpoint was the 24-hour intravenous morphine consumption, with a predefined minimal important difference set at 8 mg.
Main Findings: The trial results indicated significant reductions in 24-hour morphine consumption in the group receiving paracetamol, ibuprofen, and dexamethasone combined, compared to other groups, though none reached the minimal important difference. Specifically, this group consumed a median of 15 mg morphine, which was less than the other groups ranging from 16 mg to 24 mg. However, the differences did not meet the study’s threshold for a clinically important effect. Adverse events were lowest in the combined treatment group, suggesting a better safety profile primarily characterized by fewer incidents of nausea, vomiting, and dizziness.
Implications for Practice: The findings support the use of a combined regimen of paracetamol, ibuprofen, and dexamethasone for reducing morphine consumption post-total hip arthroplasty, which could be significant in clinical settings aiming to minimize opioid use. The improved safety profile also highlights the potential benefits of multimodal analgesia. Further research may explore the optimization of dosing schedules and long-term outcomes to enhance patient recovery and satisfaction.

ACP Guidelines for the pharmacologic management of type 2 diabetes in adults – Ann Intern Med
3 May, 2024 | 14:05h | UTCThe American College of Physicians (ACP) has issued an updated guideline focusing on the pharmacological management of type 2 diabetes. This guideline reviews the efficacy and safety of new medications, including GLP-1 agonists, SGLT-2 inhibitors, and others, emphasizing a systematic evaluation using the GRADE methodology. Key recommendations advise the integration of SGLT-2 inhibitors or GLP-1 agonists with metformin and lifestyle changes for better glycemic control and reduction in mortality and major cardiovascular events. Conversely, the use of DPP-4 inhibitors in similar therapeutic contexts is not recommended due to insufficient evidence of benefit. This guideline targets healthcare providers managing nonpregnant adults with type 2 diabetes.

ACP cost-effectiveness analysis: Newer antidiabetic medications in type 2 diabetes – Ann Intern Med
3 May, 2024 | 13:57h | UTCThis systematic review evaluates the cost-effectiveness of newer antidiabetic medications for type 2 diabetes from U.S. clinical and economic perspectives. Analyzing non-industry funded cost-effectiveness analyses (CEAs) using GRADE and Drummond criteria, the study identifies varying cost per quality-adjusted life-year (QALY) values for medications such as GLP1a and SGLT2i. It concludes that while GLP1a and SGLT2i offer low value as primary therapies due to high costs, they may present intermediate value as adjunct treatments to metformin. The study highlights the methodological variability in CEAs and the influence of drug cost and effectiveness assumptions on outcomes. The results suggest cautious interpretation in clinical decision-making due to varied evidence quality and cost-effectiveness profiles among the reviewed medications.

ACP Meta-Analysis: Comparative efficacy of newer antidiabetic agents in type 2 diabetes management – Ann Intern Med
3 May, 2024 | 13:49h | UTCThis systematic review and network meta-analysis evaluates the effectiveness and safety of modern antidiabetic drugs in managing type 2 diabetes mellitus. The study analyzed 130 publications from 84 randomized controlled trials, using GRADE criteria for evidence assessment. Sodium-glucose cotransporter-2 (SGLT2) inhibitors and glucagon-like peptide-1 (GLP1) agonists demonstrated significant reductions in all-cause mortality and major adverse cardiovascular events when compared to usual care, with SGLT2 inhibitors also showing benefits in reducing chronic kidney disease progression and hospitalizations due to heart failure. In contrast, dipeptidyl peptidase-4 (DPP4) inhibitors, insulin, and tirzepatide showed no significant mortality benefits. The study identified limitations including sparse direct drug comparisons and inadequate data for certain patient subgroups. Overall, SGLT2 inhibitors and GLP1 agonists were associated with fewer serious adverse events and severe hypoglycemia compared to insulin and sulfonylureas.

Review: Key findings from the Women’s Health Initiative studies on postmenopausal interventions – JAMA
3 May, 2024 | 13:34h | UTCThe Women’s Health Initiative (WHI) studied the impact of various interventions on postmenopausal women aged 50-79, using data from 161,808 participants between 1993 and 2018. The findings suggest that hormone therapy, specifically with conjugated equine estrogens and medroxyprogesterone acetate, does not reduce the risk of cardiovascular diseases, dementia, or other chronic conditions in postmenopausal women. It is, however, effective for managing severe menopausal symptoms when initiated before age 60 in women without contraindications. The trials also concluded that universal supplementation of calcium and vitamin D does not effectively prevent fractures and should be limited to those not meeting dietary intake recommendations. Furthermore, a low-fat diet rich in fruits, vegetables, and grains did not reduce the incidence of breast or colorectal cancer, though it may decrease breast cancer mortality rates, indicating the need for further investigation.

USPSTF Guideline: Biennial screening mammography recommended for women aged 40-74 to reduce breast cancer morbidity and mortality
1 May, 2024 | 21:45h | UTCStudy Design and Population:
The US Preventive Services Task Force (USPSTF) performed a systematic review and collaborated on modeling studies to evaluate the effectiveness of various mammography-based breast cancer screening strategies. This assessment included factors such as age of initiation and cessation of screening, screening intervals, modalities, and the use of supplemental imaging. The population studied consisted of cisgender women and all other persons assigned female at birth who are 40 years or older and at average risk of breast cancer.
Main Findings:
The USPSTF concludes with moderate certainty that biennial screening mammography for women aged 40 to 74 years provides a moderate net benefit in reducing the incidence of and progression to advanced breast cancer, as well as in decreasing breast cancer morbidity and mortality. However, the evidence is insufficient to assess the benefits and harms of mammography screening in women aged 75 and older, as well as the use of supplemental screening with ultrasound or MRI in women with dense breasts.
Implications for Practice:
Based on these findings, the USPSTF recommends biennial screening mammography for women aged 40 to 74 years. This recommendation aims to optimize breast cancer outcomes while considering the balance of benefits and harms of screening. There is a need for further research to clarify the benefits and risks associated with mammography in women older than 75 and for those with dense breasts considering supplemental screening.

Phase 2 RCT: Lixisenatide slows progression of motor disability in early Parkinson’s disease, but with notable gastrointestinal side effects
30 Apr, 2024 | 13:00h | UTCIn a phase 2, double-blind, randomized, placebo-controlled trial, the effect of lixisenatide, a glucagon-like peptide-1 receptor agonist, was evaluated for its potential to slow the progression of motor disability in patients with early Parkinson’s disease. A total of 156 patients, diagnosed within the past three years and stable on symptom-managing medications, were enrolled and equally divided into lixisenatide and placebo groups. After 12 months, the lixisenatide group showed a slight improvement in motor disability (−0.04 point change) compared to a worsening in the placebo group (3.04 point change) on the Movement Disorder Society–Unified Parkinson’s Disease Rating Scale part III. This difference was statistically significant (p=0.007). However, after a 2-month washout period, improvements were less distinct. Notably, 46% of lixisenatide-treated patients experienced nausea, and 13% reported vomiting. These findings suggest potential benefits of lixisenatide for motor symptoms in Parkinson’s disease, though further research is necessary to fully assess its efficacy and tolerability.

Meta-Analysis: Efficacy of MRI in prostate cancer screening for reducing unnecessary biopsies
28 Apr, 2024 | 20:13h | UTCThis meta-analysis evaluated the effectiveness of incorporating magnetic resonance imaging (MRI) into prostate cancer screening pathways, compared to prostate-specific antigen (PSA)–only screening strategies. Analyzing data from 80,114 men across 12 studies, the findings demonstrate that MRI-based screening, particularly when using a sequential approach and a PI-RADS score ≥3 cutoff for biopsy, significantly increases the odds of detecting clinically significant prostate cancers (OR, 4.15) while reducing unnecessary biopsies (OR, 0.28) and detection of clinically insignificant cancers (OR, 0.34). Implementing a higher PI-RADS score of ≥4 further decreased the detection of insignificant cancers and biopsies performed, without impacting the detection rate of significant cancers. These results support the integration of MRI into screening programs to enhance diagnostic precision and reduce patient harm.

Observational Study: Synergistic effects of early menopause and vascular risk on cognitive decline in postmenopausal women
27 Apr, 2024 | 18:20h | UTCStudy Design and Population:
This study analyzed data from 8,360 postmenopausal women and an equal number of age-matched male participants from the Canadian Longitudinal Study on Aging. Researchers assessed the independent and combined effects of age at menopause, vascular risk factors, and history of hormone therapy on cognitive outcomes. Participants’ cognitive function was measured using a global cognitive composite at baseline and again at a 3-year follow-up.
Main Findings:
The study found a synergistic interaction between early menopause (ages 35-48) and high vascular risk, significantly associated with lower cognitive scores at follow-up. Specifically, earlier menopause combined with higher vascular risk resulted in greater cognitive decline, compared to their individual effects. Notably, hormone therapy did not modify this association. This pattern was not observed in female participants with average or later menopause ages, nor in the age-matched male cohort.
Implications for Practice:
The findings underscore the importance of considering both endocrine and vascular health as predictive markers in dementia prevention strategies, particularly for women. These results suggest that women with early menopause and vascular risk factors should be closely monitored to mitigate their higher risk of cognitive impairment.

Retrospective Cohort Study: Delirium associated with increased risk of subsequent dementia and higher mortality in older adults
27 Apr, 2024 | 15:54h | UTCStudy Design and Population:
This retrospective cohort study utilized hospital administrative data from both public and private hospitals in New South Wales, Australia, spanning from July 2001 to March 2020. The study examined data from 650,590 patients aged 65 years or older, who did not have dementia at baseline. Diagnoses of dementia and delirium were identified using ICD-10 codes. The cohort was carefully matched into 55,211 pairs based on personal and clinical characteristics, focusing on those who developed delirium and their outcomes over a follow-up period exceeding five years.
Main Findings:
The analysis found that patients who experienced delirium had a 39% increased risk of mortality (hazard ratio: 1.39, 95% CI: 1.37-1.41) and a threefold increase in the risk of developing dementia (subdistribution hazard ratio: 3.00, 95% CI: 2.91-3.10) compared to those without delirium. The risk associated with dementia was notably stronger among men. Furthermore, each additional episode of delirium was linked to a 20% increased risk of subsequent dementia (subdistribution hazard ratio: 1.20, 95% CI: 1.18-1.23).
Implications for Practice:
The strong association between delirium and increased risks of death and incident dementia in older adults highlights the importance of delirium as a clinical marker that warrants significant attention. These findings suggest that enhanced monitoring and management of delirium in hospital settings could be crucial for identifying patients at higher risk of adverse outcomes, including dementia. Efforts to improve delirium management might not only address immediate clinical needs but also assist in stratifying risk and tailoring post-discharge care plans to better support the long-term health of these patients. Further research is needed to explore effective strategies for delirium intervention and to determine how these approaches can impact long-term cognitive outcomes and overall mortality.

Cohort Study: Higher serious bleeding rates linked to diltiazem in elderly atrial fibrillation patients on anticoagulation
26 Apr, 2024 | 12:35h | UTCStudy Design and Population:
This retrospective cohort study analyzed data from 204,155 Medicare beneficiaries aged 65 years or older diagnosed with atrial fibrillation. The study focused on new users of the anticoagulants apixaban or rivaroxaban who commenced treatment with either diltiazem or metoprolol between January 2012 and November 2020, with follow-up extending up to 365 days.
Main Findings:
Patients treated with diltiazem exhibited a significantly increased risk of serious bleeding, including bleeding-related hospitalization and death, compared to those treated with metoprolol. The hazard ratio (HR) for serious bleeding events was 1.21, with a rate difference (RD) of 10.6 per 1000 person-years. Notably, the risk escalated with diltiazem doses exceeding 120 mg/day, indicating a dose-response relationship. Secondary outcomes, such as ischemic stroke or systemic embolism, did not show significant differences between the treatment groups.
Implications for Practice:
The findings suggest that in older adults with atrial fibrillation treated with apixaban or rivaroxaban, diltiazem increases the risk of serious bleeding, especially at higher doses. These results underscore the importance of cautious medication management and might influence clinical decisions regarding the choice of ventricular rate control in this population.

Cohort Study: Increased fracture risk linked with initiation of antihypertensive medication in older veterans
26 Apr, 2024 | 12:29h | UTCStudy Design and Population:
This retrospective cohort study evaluated the association between antihypertensive medication initiation and fracture risk among older long-term care nursing home residents within the Veterans Health Administration. Conducted from 2006 to 2019 with data analysis spanning 2021 to 2023, the study utilized target trial emulation techniques and included 29,648 residents. A 1:4 propensity score-matched method was employed to compare medication initiators with non-initiators.
Main Findings:
Out of the matched cohort of 64,710 residents, those who initiated antihypertensive medication showed a higher incidence of fractures (5.4 per 100 person-years) compared to controls (2.2 per 100 person-years). The adjusted hazard ratio for fractures was 2.42. Notably, higher risks were observed in subgroups with dementia or elevated blood pressure thresholds (systolic ≥140 mm Hg or diastolic ≥80 mm Hg). Risks for severe falls and syncope were also elevated in the medication-initiating group.
Implications for Practice:
The study indicates a significant association between the initiation of antihypertensive medications and increased fracture risks among older, frail nursing home residents. Given these findings, clinicians should exercise caution and consider enhanced monitoring and preventive strategies when prescribing these medications to this vulnerable population.

RCT: Lack of significant effect of Paxlovid (nirmatrelvir–ritonavir) on symptom alleviation in Covid-19
26 Apr, 2024 | 11:49h | UTCStudy Design and Population:
This phase 2–3 randomized clinical trial investigated the efficacy of nirmatrelvir in combination with ritonavir for treating mild-to-moderate Covid-19 in adults. Participants, both vaccinated and unvaccinated, were enrolled based on their risk factors for severe Covid-19. The study included 1296 adults who had confirmed Covid-19 with symptom onset within the past 5 days. They were randomly assigned to receive either nirmatrelvir–ritonavir or placebo every 12 hours for 5 days.
Main Findings:
The primary endpoint was the time to sustained alleviation of all targeted Covid-19 signs and symptoms. Results showed that the median time to alleviation was 12 days for the treatment group and 13 days for the placebo group, a difference that was not statistically significant (P=0.60). Hospitalizations and deaths were slightly lower in the treatment group (0.8%) compared to the placebo group (1.6%), but this difference was also not statistically significant. Adverse events were similar across both groups, with dysgeusia and diarrhea being the most common in the treatment group.
Implications for Practice:
The findings indicate that nirmatrelvir–ritonavir treatment does not significantly reduce the time to symptom alleviation for Covid-19 compared to placebo among vaccinated or unvaccinated adults. These results suggest that further research is needed to explore the potential benefits of this treatment in specific subpopulations or in combination with other interventions.
