Episode 431: 438. CME- What To Do AFTER PE Diagnosis

we unpack whether rivaroxaban followed by aspirin improves thromboprophylaxis after hip and knee arthroplasty, put oral GLP-1 therapy orforglipron head-to-head with dapagliflozin for type 2 diabetes, and examine new evidence on venous thromboembolism after mechanical restraint in psychiatric hospitals. We also translate updated pediatric functional-constipation guidance, the newest ACG recommendations for colonic diverticulitis, and real-world data on blood-pressure control and mortality among U.S. veterans—then finish with a practical look at whether a lumbar belt can truly ease nonspecific low-back pain.Shivakumar S, et al.

Does a Coronary Artery Calcium (CAC) scan still earn its place in modern cardiovascular prevention? This podcast cuts through the headlines to examine the recent research, challenge overconfident conclusions, and put CAC testing under the microscope alongside the PREVENT risk equation.Each episode brings a sharp, evidence-first look at what calcium scoring can—and cannot—tell us about heart-attack risk. We unpack study methods, question the assumptions behind new publications, and ask the practical questions clinicians and patients actually need answered: When does CAC meaningfully change care? Who benefits most? And in an era of PREVENT, does a scan add actionable information beyond the numbers?Clear-eyed, clinically grounded, and never afraid to interrogate the data, this is the podcast for anyone who wants the real value of CAC—not just the latest claim.

Jafari K, et al. Risk factors for pediatric deep neck infection revisit after emergency department discharge for pharyngitis or localized neck symptoms. Ann Emerg Med 2026 May; 87:605. DOI: 10.1016/j.annemergmed.2025.10.007. In a “look-back” analysis of some 800 children admitted with deep neck infection, 18% had at least one ED discharge before admission. The most common discharge diagnoses were fever, pharyngitis/tonsillitis, and localized neck symptoms. In a “look-forward” analysis, 0.01% of about 400,000 children diagnosed with pharyngitis/tonsillitis and 0.07% of almost 60,000 children presenting with nontraumatic neck symptoms were subsequently admitted with a deep neck infection.  Klausen MK, et al. Once-weekly semaglutide versus placebo in patients with alcohol use disorder and comorbid obesity: A randomised, double-blind, placebo-controlled trial. Lancet 2026 May 2; 407:1687. Heavy drinking decreased from 17 days per month at baseline to 13 with placebo and 10 with semaglutide — a significant 3-day difference. Days without any alcohol use in the past month increased from 9 at baseline to 11 with placebo and 12 with semaglutide, though this difference was not significant (P=0.051).  https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2848777Conclusions and Relevance  In this RCT of 651 AWS, varenicline sampling was efficacious, with potentially superior outcomes compared with NRT.    https://jamanetwork.com/journals/jama/fullarticle/2848997Conclusions and Relevance  Among childbearing physicians in training, a parental support package significantly mitigated postpartum burnout. https://pubmed.ncbi.nlm.nih.gov/42120723/. These data demonstrate orforglipron's potential as a globally scalable option for minimizing weight changes after injectable therapy. Trial limitations include the absence of a comparator arm involving continued use of injectable obesity-management medications and the trial's 1-year duration. https://pubmed.ncbi.nlm.nih.gov/42104164/mong 263 clinicians (107 residents, 156 specialists), specialists scored higher than residents (median, 46 [IQR, 42-50] vs 41 [IQR, 36-46]; P < .001; r = 0.32). ChatGPT correctly diagnosed 53 of 61 cases (86.9%), Gemini 50 (82.0%), and Copilot 44 (72.1%). Both ChatGPT and Gemini exceeded the upper bound of the specialist population median 95% CI (47.17).  https://www.nejm.org/do/10.1056/NEJMdo008444/full/Among patients with noncardioembolic ischemic stroke or high-risk TIA treated with antiplatelet therapy, asundexian at a daily dose of 50 mg resulted in lower risks of ischemic stroke and major cardiovascular events than placebo, without a higher risk of major bleeding.
