https://www.jthjournal.org/article/S1538-7836(25)00109-6/fulltextAntithrombotic agents, like aspirin and anticoagulants, are essential for treating many cardiovascular conditions. However, a common side effect is bleeding, with extracranial bleeding—bleeding outside the brain and spinal cord—being quite prevalent. This study, a secondary analysis of the Aspirin in Reducing Events in the Elderly, or ASPREE trial, aimed to explore how clinically significant extracranial bleeding affects the development of functional disability in otherwise healthy older adults.What did the researchers find?Summary of Findings: Incidence of Bleeding: Out of nearly 19,000 participants, about 2.9%, or 547 individuals, experienced clinically significant extracranial bleeding. Functional Independence Impact: Those who experienced such bleeding had a more than two-fold increase in the risk of developing dependence on activities of daily living, or ADLs. Specifically, the hazard ratio for ADL dependence was 2.46, indicating a signif

https://jamanetwork.com/journals/jama/article-abstract/2834632SummaryThe article examines the effectiveness and safety of zilebesiran, an RNA interference therapeutic agent, when used in combination with standard first-line antihypertensive drugs for patients with inadequately controlled hypertension. The phase 2, prospective, randomized, double-blinded trial was conducted over multiple international sites with patients treated with either indapamide, amlodipine, or olmesartan. The primary outcome measured was the change in 24-hour mean ambulatory systolic blood pressure (SBP) at three months.Key findings from the study showed that a single subcutaneous dose of zilebesiran significantly reduced 24-hour mean ambulatory and office SBP at three months compared to placebo, across all background treatments. This indicates that zilebesiran can be an effective adjunctive treatment to standard oral antihypertensive therapies, providing sustained blood pressure control.Strengths Innovative Approach: The use of RNA in

These markers contribute independently to long-term cardiovascular risk beyond traditional 10-year risk estimates. Study Design and Population: The study enrolled 27,939 initially healthy U.S. women who were followed for 30 years. The primary endpoint was the occurrence of a first major adverse cardiovascular event, including myocardial infarction, coronary revascularization, stroke, or death from cardiovascular causes. Predictive Strength of Biomarkers: Among the biomarkers, high-sensitivity CRP showed the strongest association with future cardiovascular events (hazard ratio for top quintile: 1.70). LDL cholesterol and lipoprotein(a) also significantly predicted risk, albeit to a slightly lower degree (hazard ratio

Desgagnés N et al. Use of albumin-adjusted calcium measurements in clinical practice. JAMA Netw Open 2025 Jan 21; 8:e2455251. (https://doi.org/10.1001/jamanetworkopen.2024.55251)Overall, total calcium levels (just the ones we would get back on a basic cmp) correlated better with ionized calcium than did formula-corrected calcium levels. Formulas with stronger correlation than total calcium levels were either complex (e.g., requiring blood pH measurement) or derived locally (i.e., not generalizable). Many formulas overestimated calcium at low calcium levels; the Payne formula misclassified 41% of patients, whereas the total calcium level only misclassified 25% of patients.

https://www.nejm.org/doi/10.1056/NEJMoa2416394At 72 weeks, the mean percentage decrease in weight was significantly greater with tirzepatide than with semaglutide (20% vs. 14%). Gastrointestinal side effects occurred frequently in both groups but led to discontinuation of treatment in only 3% and 6% of participants in the tirzepatide and semaglutide groups, respectively. Injection-site reactions were more common with tirzepatide than with semaglutide (9% vs. <1%) but didn't cause participants to stop treatment.

https://jamanetwork.com/journals/jamainternalmedicine/fullarticle/2832701In this multisite trial, 800 adults who smoked 10 or more cigarettes daily (mean duration of smoking, ≈35 years) were randomized to 6 or 12 weeks of cytisinicline or to placebo. In the 6-week group,15% of cytisinicline recipients and 6% of placebo recipients were abstinent (defined by self-report and breath carbon monoxide <10 ppm) during weeks 3 to 6. In the 12-week group, 30% of cytisinicline recipients and 9% of placebo recipients were abstinent during weeks 9 to 12.

Aryee EK et al. Prevalence of obesity with and without confirmation of excess adiposity among US adults. JAMA 2025 Apr 17; [e-pub]. (https://doi.org/10.1001/jama.2025.2704)The rate of obesity was 39.7% based on BMI and 39.1% based on excess adiposity. Among participants with obesity based on BMI, 98% also had excess adiposity; in other words, essentially the same individuals were considered as obese by both criteria.

In an hour-by-hour analysis, patients we suspect to have asthma are significantly more likely to have positive bronchodilator responses early in the morning; with each passing hour before testing, there was small decrease (8%) in positive response. Patients also were more likely to have positive responses in the winter. Knox-Brown B et al. Effect of time of day and seasonal variation on bronchodilator responsiveness: The SPIRO-TIMETRY study.

Whether routine use of spironolactone is beneficial after myocardial infarction is uncertain.  Recent attempts to improve outcomes with intensified renin–angiotensin–aldosterone inhibition have not shown improvements in outcomes.7,8 A trial of routine aldosterone antagonism with spironolactone in addition to standard therapy among 1603 patients after myocardial infarction without heart failure showed no improvement in outcomes.9  https://pubmed.ncbi.nlm.nih.gov/27102506/   “ In a non-pre-specified exploratory analysis, the odds of death were reduced in the treatment group (3 [0.5%] vs. 15 [2.4%]; HR: 0.20; 95% CI: 0.06 to 0.70) in the subgroup of ST-segment elevation MI (n = 1,229), but not in non-ST-segment elevation MI (p for interaction = 0.01).”’ However, there was a significant reductio

Estimated 5-year incidence of recurrent VTE was similar in the reduced-dose and full-dose groups (2.2% and 1.8%). Estimated 5-year bleeding incidence was significantly lower with reduced-dose than with full-dose treatment (2.1% vs. 4.0% for major bleeding; 8.6% vs. 11.5% for clinically relevant nonmajor bleeding). Outcomes with apixaban and rivaroxaban were similar. Couturaud F et al.
