Prospective study finds cherry angiomas are much more common in NF1 patients (48%) than controls (18%), with somatic second hits in NF1 predominantly in endothelial cells and telocytes, supporting a model where biallelic NF1 loss drives these vascular lesions; co-occurring GNAQ variants and UV mutagenesis suggest a shared origin and broader NF1-related vasculopathy.
The American Medical Association, in partnership with the Digital Medicine Society, released a framework arguing that physicians must remain central to patient care as AI technologies evolve, stressing human connection, clinical judgment, and responsible use of technology amid ongoing debates about AI potentially replacing doctors and the need for regulation and reimbursement frameworks.
CNN argues that today’s wellness boom echoes the Middle Ages, with bloodletting, cupping and purges resurfacing alongside energy healing and influencer‑driven cures, driven by distrust in public health after Covid; while some medieval ideas—such as humors or urinalysis—had observational roots, they were superseded by modern science. The piece contrasts Europe’s trust crisis with the Islamic world’s public‑health policies, and it concludes the similarities are superficial: today’s trends reflect social distrust rather than a true regression of medicine, even as people seek simple explanations amid information overload.
A perspective in The American Journal of Clinical Nutrition argues for a paradigm shift in hypertension prevention: boosting dietary potassium while reducing sodium can more effectively control blood pressure than sodium reduction alone, supported by evidence on potassium’s independent BP-lowering effect and the renal potassium switch; it recommends targeting sodium-to-potassium ratios in food reformulation, expanding education on potassium-rich foods, and policies to improve access to such foods, with potassium-enriched salt substitutes as a near-term option (not for those with kidney disease), while sodium reduction remains foundational.
Bryan Johnson is detailing Kate Tolo's 100-day, data-heavy study of her menstrual cycle, using more than 50 devices (including a 'techno tampon') to collect about 14 million data points with a 12-person medical team, and plans to publish all results and potential interventions as the baseline is established.
Despite medical advances, women’s health has long been sidelined. Perimenopause is used to show how societal norms, historical bias in medicine, and cultural skepticism shape care for women. The piece argues progress requires better research focused on women, trusted medical information, and equal agency in healthcare decisions.
A 47-year-old woman with autoimmune Hashimoto’s thyroiditis who had total thyroidectomy showed dramatic LDL-C elevations during profound hypothyroidism, driven by reduced LDL receptor activity and increased PCSK9; LDL-C levels improved markedly when euthyroidism was restored with levothyroxine. The case highlights hypothyroidism as a reversible, non-genetic cause of severe hypercholesterolemia and emphasizes evaluating thyroid function before diagnosing familial hypercholesterolemia or initiating lipid-lowering therapy.
Small language models (SLMs) offer a scalable, practical alternative to large language models for medical tasks, enabling broader real-world deployment across diverse clinical settings, but they trade off some accuracy and robustness and require careful evaluation, domain adaptation, and governance to address safety and integration challenges.
Dr. Jeremy Faust, a Brigham and Women’s Hospital emergency physician, blends lifesaving care with boundary-pushing journalism through his Inside Medicine Substack, delivering timely scoops to about 85,000 subscribers—including an early report on hantavirus aboard the MV Hondius—while also conducting the Longwood Chorus.
A Verge interview/profile of Dr. Zachary Rubin, a pediatric allergist/immunologist who uses TikTok, Instagram, and YouTube to counter health misinformation and empower viewers to think critically about health claims. He stresses that uncertainty is a strength of science and that misinformation spreads quickly online, posing a major challenge. Rubin aims to bring the doctor’s office discussions to a wider audience, drawing on his book All About Allergies and collaboration with fellow clinician Dr. Idrees Mughal, while urging improved scientific literacy and clearer, transparent communication from scientists to maintain public trust.
A meta-analysis of 23 randomized trials including 2,028 patients with chronic musculoskeletal conditions found melatonin reduced pain intensity by about 9 points on a 100-point scale and improved sleep quality. Doses ranged 3–10 mg (commonly 3 mg) taken at bedtime, with safety similar to placebo and mostly mild side effects like nausea, dizziness, or headaches. The researchers caution melatonin should complement—not replace—standard treatments and advise discussing use with a doctor, especially when other meds or health conditions are involved.
In two major trials of enzalutamide for advanced prostate cancer, up to about 25% of patients showed radiographic progression on imaging despite stable or undetectable PSA levels, correlating with worse survival. The findings suggest PSA monitoring alone may miss disease growth, underscoring the value of periodic imaging—especially in the first two years—and may prompt updates to clinical guidelines. Possible mechanisms include tumors evolving to grow independent of androgen receptor signaling through lineage plasticity or neuroendocrine transformation.
A UK IFS analysis finds degree earnings vary by subject: medicine can add up to about £400,000 over a lifetime versus non-graduates, while economics also yields strong returns, whereas arts, philosophy, and languages often offer little or negative financial advantage. On average, graduates earn roughly £100,000 more across a lifetime, but about a quarter may be financially worse off than non-graduates. The findings come as the government considers capping low-return courses and introducing minimum English-language requirements for student finance, with debates on whether alternative routes like apprenticeships can offer viable paths.
A NEJM study shows OpenAI's o3 model aided doctors at Boston Children's Hospital in diagnosing 18 children with previously unsolved rare illnesses, using AI as a diagnostic tool under physician oversight to reach new diagnoses and guide treatment.
A roundup of doctors’ warnings about dangerous health trends, ranging from cannabis-related conditions (CHS) and THC-induced psychosis in young people, to rising vaping, ketamine misuse, and GLP-1 drug abdominal pain. The piece also highlights risky behaviors like energy‑drink overuse and sleep deprivation, unsafe sexual practices with lifelong treatment needs, heavy reliance on social media and screens affecting development, overuse of tablets in patient care, and nitrous oxide abuse. Together these trends illustrate how pop culture, access to medications, and modern technology are shaping troubling health patterns across age groups.
