433. Salt, Statins, and Stents
2026/04/21
Donato J, et al. Things We Do For No Reason™: Low salt diets for patients with acute heart failure. J Hosp Med 2026 Feb 4; [e-pub]. DOI: 10.1002/jhm.70278.Some guidelines now recommend "normal sodium intake" for patients with acute and chronic HF, which means avoiding excessive sodium intake and staying under 4 to 5 g daily. https://academic.oup.com/eurjhf/article-abstract/26/4/730/8328801?redirectedFrom=fulltext&login=trueLuo Y, et al. Measuring public preferences for statin therapy: Using the smallest worthwhile difference. JAMA Intern Med 2026 Feb 16; [e-pub]. DOI: 10.1001/jamainternmed.2025.7958.  It's honestly kind of beautiful - and a little frustrating. But it's also a reminder that medicine isn't math; it's human. People don't just want statistics; they want clarity, control, and context. A one-percent drop means one thing on paper, and something very different when you're trying to remember if you already took today's pill.  Kang J, et al. Aspirin versus clopidogrel for chronic maintenance monotherapy after percutaneous coronary intervention: 10-year follow-up of the HOST-EXAM trial. Lancet 2026 Apr 11; 407:1439. DOI: 10.1016/S0140-6736(26)00422-8.Over ten years, about 25 out of 100 patients on clopidogrel had one of these events, compared to about 29 out of 100 on aspirin. Statistically, that’s a hazard ratio of 0.86, with a p value of 0.005, and it translates into an absolute risk reduction of just over 3 percent and a number needed to treat of about 33. In other words, if you treat 33 stable post‑PCI patients with clopidogrel rather than aspirin for ten years, you prevent one net adverse event. Looking only at thrombotic events—cardiovascular death, non‑fatal MI, ischemic stroke, ACS readmission, or stent thrombosis—clopidogrel again came out ahead: roughly 17 percent vs 20 percent, hazard ratio 0.82, p around 0.002. This difference was largely driven by fewer strokes and fewer rehospitalizations for acute coronary syndromes. Now for bleeding. You might worry that better antithrombotic protection would mean more bleeding. In fact, the opposite happened. Any clinically relevant bleeding, BARC type 2 or higher, occurred in about 9 percent of clopidogrel patients versus almost 11 percent on aspirin, with a hazard ratio of 0.81. Major bleeding—BARC type 3, including haemorrhagic stroke—was also lower on clopidogrel: about 5.6 percent vs 7.7 percent. Haemorrhagic stroke itself was cut roughly in half.

431. Gout should we treat to a number? Is Co-testing needed?
2026/04/14
https://www.sciencedirect.com/science/article/abs/pii/S2665991326000342?via%3Dihub lancet rheumatology   A treat-to-target strategy versus symptom-driven management of gout in the Netherlands (GO TEST Overture): a multicentre, open-label, pragmatic, superiority, randomised controlled trial     The question on the table: Is chasing a serum urate level below six milligrams per deciliter worth the effort? Or are we just torturing our patients with more lab draws and dose titrations than they actually need?  What’s the Real Takeaway? So — is it worth chasing six? Probably yes, but let's keep expectations realistic. Think of it like aiming for LDL targets in dyslipidemia — specific numbers keep us intentional, The bottom line: when your gout patient agrees to start urate-lowering therapy,  don’t expect miracles overnight. Lower urate just tilts the odds for fewer flares — it doesn’t guarantee smooth sailing for every patient.https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2846208   HPV, Cytology, and Cotest Cervical Cancer Screening and the Risk of Precancer     Let’s start with the basics. For years the Pap test, or cytology, has been the main tool for catching early changes on the cervix. More recently, we’ve added tests that look directly for HPV, the virus that actually causes most cervical cancers. Some places now do both at the same time, called “cotesting.” It sounds like more must be better, right? A big study out of British Columbia followed over eight thousand women for up to ten years after they had both tests done at the same visit. The researchers wanted to know: if your HPV test is negative, does adding that extra Pap result actually help keep you safer in the long run? Here’s what they found. If a woman’s HPV test was positive and her Pap looked abnormal, her chance of developing a significant precancer over time was pretty high, more than 40%. If the HPV test was positive but the Pap looked normal, the risk was lower, but still real—over 20%. Those are the folks we definitely want to follow closely. But once the HPV test was negative, the story changed. Whether the Pap looked normal or a bit off, the risk of serious precancer over the following years stayed very low—well under 5%, and for most women under 1%. In fact, women who were HPV‑negative had almost the same low risk as women whose HPV and Pap were both negative, but adding that Pap test made screening more complicated and more expensive for very little extra benefit. So what does this mean in plain language? If your HPV test is negative, you’re in a very low‑risk group for cervical precancer for many years, even if your Pap result isn’t perfectly pristine. Doing both tests on everyone, every time, doesn’t buy much extra safety, but it does add cost and can lead to more follow‑up procedures that many women don’t actually need.
430. Hormone Replacement Therapy and the Black Box Warning
2026/03/24
Let’s rewind to the early 2000s. Flip phones were cool, low-rise jeans were a crime, and the Women’s Health Initiative—WHI—dropped what became the medical equivalent of a headline: “Hormone Therapy Increases Risk!” The study looked at one very specific regimen: an oral pill with conjugated equine estrogens—yes, horse estrogens—and medroxyprogesterone acetate, or MPA, taken every day by women with an average age of 63. Now, 63 is not “just hit menopause.” That’s about 12 years past menopause for most women. So we were basically taking a therapy usually started around 50, testing it in women in their early 60s, and then pretending that result applied to everyone, at every age, on every dose, with every type of hormone, in every form—patch, pill, gel, ring, cream, you name it. Imagine testing one fast-food burger in 63-year-olds and then announcing: “All food is dangerous. Consider only lettuce, and maybe not too much of that either.” Let’s do a quick myth-versus-reality lightning round. Myth: “All hormone therapy causes breast cancer.”Reality: The best current data do not support a blanket statement like that. In many analyses, especially for women who start near menopause, breast cancer risk is small, nuanced, and depends on the specific regimen and individual risk factors. Estrogen alone has even been associated with lower breast cancer mortality compared to placebo in long-term WHI follow‑up. Myth: “You should take as little as possible for as short as possible, no matter what.”Reality: Your dose and duration should match your symptoms, your risk profile, and your goals. There is no magical stopwatch at 5 years where your body alarms go off. It’s a conversation, not a countdown. Myth: “Vaginal estrogen is as risky as full-body hormone therapy.”Reality: Local vaginal therapies were unfairly swept under the same warning umbrella, despite very different absorption and risk profiles. The new product-specific approach is meant to fix that.
429. Rivaroxaban vs Apixaban = The Battle of the Blood Thinners!
2026/03/20
— rivaroxaban versus apixaban. Yes, folks, this is The Battle of the Blood Thinners! And spoiler alert — one of them came out looking like the overachiever in a safety class... while the other probably needs a little extra padding on its report card. The Setup So here’s the story. For years, observational studies hinted that apixaban — we’ll call it “Api” because we’re friendly like that — might be gentler when it comes to bleeding compared to rivaroxaban — or “Riva,” who sounds like she’d stir drama on a reality show. But now, for the first time ever, we’ve got a head-to-head trial. Picture a randomized cage match… but with 2,800 patients who probably just wanted their deep vein thrombosis or pulmonary embolism treated quietly. These brave participants, average age 58, were split—half got apixaban, half got rivaroxaban. Researchers then followed them for three suspense-filled months. The Results (and the Punchline) Here’s the headline:Clinically relevant bleeding was twice as likely with rivaroxaban compared to apixaban.Yup—7.1% versus 3.3%. That’s a difference big enough to make any hematologist clutch their coffee mug a little tighter. And if you love a good number — the number needed to harm here is 26. That means for every 26 patients you put on rivaroxaban instead of apixaban, one extra person might have a bleeding episode you wish hadn’t happened. Major bleeding? Rivaroxaban also took home that dubious award — 2.4% versus 0.4%.Ouch. That’s like comparing a paper cut to an artery leak.Why the Difference? The researchers think rivaroxaban’s longer initial high-dose period may explain the extra bleeding drama early in treatment.
428. Asthma and Stroke --- A breathless combination
2026/03/13
Minocycline in Acute Ischemic Stroke (EMPHASIS trial) A multicenter, double-blind RCT in China studied 1,724 patients with acute ischemic stroke treated within 72 hours of onset. Patients received either a 4.5-day course of oral minocycline or placebo. Minocycline works by inhibiting microglial activation, which contributes to post-stroke inflammation. Primary outcome: 52.6% of minocycline patients vs. 47.4% of placebo patients achieved good functional recovery (mRS 0–1) at 90 days (p=0.0061). Safety: No difference in adverse events. Practice impact: Clinicians are cautiously optimistic; further positive trials could lead to selective use of minocycline in AIS patients. 2. Tenecteplase for Basilar Artery Stroke (TRACE-5 trial) This phase 3 RCT in China tested IV tenecteplase given within 24 hours of ischemic basilar artery occlusion against standard medical care (both groups could undergo thrombectomy). Results: At 90 days, 38% of tenecteplase patients vs. 29% of controls had no or minimal disability (mRS 0–1 or baseline). Safety: Similar rates of intracranial hemorrhage (2–3%) and mortality (29–31%). Practice impact: Promising expansion of the thrombolytic window for severe posterior strokes; more evidence needed before routine use outside research settings.
427. Kawasaki disease-no, not the motorcycle company
2026/03/11
Today, we're talking about Kawasaki disease-no, not the motorcycle company, though sometimes treating it does feel like trying to ride one at full speed through uncertainty.For decades, high-dose aspirin was basically the holy water of Kawasaki treatment. Eighty to a hundred milligrams per kilogram per day-because apparently, kids with vasculitis also needed a little side of tinnitus. But here's the twist: new research says... maybe we didn't need all that aspirin after all.Researchers at one hospital decided to mix things up. First, they treated 300 kids with the traditional high-dose aspirin. Then they switched the policy and gave the next 200 kids low-dose aspirin-3 to 5 mg/kg/day. Everyone got IVIG, because we're not completely reckless.   And the results? Drumroll please-no difference.   That's right. About 20% of kids in both groups needed IVIG a second time, and their coronary arteries looked... equally fine. The median max Z-score was 1.6 in both groups. (For the non-cardiologists out there, that's comfortably under aneurysm territory, which starts at 2.0.)   Basically, the low-dose kids did just as well-and none of them had to choke down near-toxic amounts of aspirin. So, high-dose: meet low benefit. Low-dose: meet my new best friend.
426. Go Big or Go Partial? The Knee Replacement Showdown
2026/03/10
Setting the stage Picture this: your knee is like a three-room apartment. You've got a medial room, a lateral room, and a patellofemoral room. In isolated anteromedial osteoarthritis, just one room is trashed. The rest of the apartment still looks like something you'd put on a rental listing.   So surgeons have two choices:   Option A: Total knee arthroplasty, or TKA - bulldoze the entire apartment and rebuild it.   Option B: Medial unicompartmental knee arthroplasty, or UKA - fix the one bad room and leave the rest alone.   Previous work suggested that partial knees can actually hold up pretty well when only that medial compartment is involved. But we needed a high-quality, double-blind, multicenter randomized trial to really settle the argument-because if there's anything surgeons love more than power tools, it's being right.   The Danish showdown Enter Denmark, land of bicycles, universal healthcare, and apparently, a lot of unicompartmental knees. UKA is done more often there than in many other countries, which means they actually have surgeons who are very good at it.   In this new trial, 350 patients with isolated anteromedial osteoarthritis were randomized to either:   Medial unicompartmental knee arthroplasty (UKA), or   Total knee arthroplasty (TKA).   All participating surgeons had substantial experience with both procedures-important, because UKA is more technically demanding. This is not the operation you want someone learning from a YouTube video the night before.   And here's the fun methodological twist: for the first year, both the patients and the evaluators were blinded to which procedure had been done. That's right-people walking around with brand-new metal hardware in their knees, and no one was allowed to know which version they got. It's like the orthopedics version of a mystery box subscription.   What did they measure? The primary outcome was improvement on a standardized 48-point scale reflecting pain and function over 2 years-essentially, "how good does your knee feel, and what can you do with it?"     They also looked at a bunch of secondary outcomes: different aspects of pain, day-to-day function, range of motion, and so on.   So: same surgeons, similar patients, blinded follow-up, partial versus total. Let's talk results.   Drumroll: who won? At the 2-year mark:   The average improvement on the primary pain-and-function scale was better with UKA than with TKA.   The mean difference was 3.5 points, and the threshold for "minimal clinically important difference" was considered 4 points. So UKA got very close-call it "clinically almost important, but statistically clearly better."
425. Triptan initiation and cerebrovascular events
2026/03/06
Kalapura C, et al. Triptan initiation and cerebrovascular events in patients with migraine: A nationwide cohort study. J Am Heart Assoc 2026 Feb 17; 15:e043409. DOI: 10.1161/JAHA.125.043409.     Today, we're talking triptans - those long-trusted migraine relievers - and a new study that asks a not-so-relaxing question: could they slightly raise the risk of ischemic stroke?   Let's break it down. Researchers analyzed data from 870,000 adults with migraine and no previous vascular events. The median age was 40, and about three-quarters were women. The team compared those who started triptans with those who didn't, adjusting carefully for age, health, and baseline risk factors.   Here's the headline number: over roughly seven years, people who started triptans had an ischemic stroke rate of 3.4 per 1000 person-years, compared to 1.7 per 1000 for nonusers. That's an absolute risk difference of just 0.17% per year, or, in practical terms, about one additional stroke for every 588 people treated annually.   So yes - there's a difference, but we're not talking about a massive public health crisis. It's more "tiny spark," not "raging inferno."   Now, the nuance. The patients in this analysis were relatively young and healthy. That small risk bump might carry more weight in older populations or in people with multiple vascular risk factors - things like hypertension, high cholesterol, or smoking. In other words, if you have a few checkmarks on the cardiovascular risk list, triptans may deserve a second thought before reaching for the prescription pad.   But for most migraine patients? Nothing earth-shattering here. Triptans remain highly effective and, for many, life-changing. The key phrase is informed decision-making.   As one clinician commented about the findings, it's all about balance: avoid triptans in patients with known cardiovascular disease, but for others, it's a reasonable discussion. If the medication helps someone reclaim their day from the grip of a migraine, a small increase in vascular risk may be worth it - as long as everyone's eyes are open to the trade-off.   It's another reminder that medicine rarely deals in absolutes. Every "yes" has a "maybe," and every prescription deserves a conversation - preferably one that doesn't start with a panicked Google search at 2 a.m.   So, the clinical takeaway: triptans may modestly increase ischemic stroke risk, but in context, they remain safe for most healthy migraine patients. Awareness matters more than alarm.
424. GLP1 and NAION
2026/03/05
Li H-Y, et al. GLP-1 receptor agonists and risk of optic nerve or vision-threatening events in patients with type 2 diabetes or cardiometabolic diseases: A meta-analysis of randomized controlled trials. Diabetes Care 2026 Mar 1; 49:526. DOI: 10.2337/dc25-1929. Heberer K, et al. New-onset nonarteritic anterior ischemic optic neuropathy and initiators of semaglutide in US veterans with type 2 diabetes. JAMA Ophthalmol 2026 Feb 12; [e-pub]. DOI: 10.1001/jamaophthalmol.2025.6262. Noh Y, et al. Glucagon-like peptide 1 receptor agonists and risk of nonarteritic anterior ischemic optic neuropathy in patients with type 2 diabetes. Diabetes Care 2026 Feb 17; [e-pub]. DOI: 10.2337/dc25-2577.         Nonarteritic anterior ischemic optic neuropathy is the kind of diagnosis that makes every clinician's stomach drop: sudden, often permanent vision loss, and not much we can do about it. It has always been rare, but a growing body of work is now pointing to a possible link with one of the most widely discussed drug classes in medicine: GLP-1 receptor agonists.   Three new studies add fuel to that conversation. First, a large meta-analysis pooled 20 randomized trials with about 80,000 participants-mostly people with type 2 diabetes followed for roughly three years. In that dataset, GLP-1 agonists did not increase a composite of serious ocular events and did not show a signal for ischemic optic neuropathy specifically. On the surface, that sounds reassuring.   But the observational data tell a more worrying story. In a U.S. veterans cohort of around 100,000 patients with type 2 diabetes already on metformin, investigators compared add-on semaglutide to add-on empagliflozin over a median of two years. The rate of NAION was higher with semaglutide-about 123 versus 67 events per 100,000 person-years. A separate analysis using a U.K. primary care database of roughly 500,000 people with type 2 diabetes found a similar pattern: those starting a GLP-1 agonist had a higher 1-year risk of NAION than those starting a DPP-4 inhibitor (18.5 vs. 7.2 events per 100,000 person-years).   These new results line up with prior observational work suggesting roughly a doubling of NAION incidence among GLP-1 users. So why the disconnect with the meta-analysis of randomized trials? It's almost certainly about design rather than biology. None of the trials were built to capture rare, unexpected eye events: vision outcomes weren't prespecified, routine eye exams weren't mandated, and the definitions of ocular safety events were inconsistent. In that setting, a signal as uncommon as NAION can easily be undercounted or missed entirely.   What should clinicians do with this? For most patients, the cardiometabolic benefits of GLP-1 agonists will still far outweigh a very small absolute risk of a rare optic neuropathy. But when we start or continue these drugs, especially in patients who already have vascular risk factors for eye disease, it's reasonable to add one more line to the counseling script: there is a rare association with NAION, and any sudden change in vision warrants urgent evaluation. This isn't a reason to abandon GLP-1s-but it is a reminder that even our most promising therapies can carry risks we only discover once they're widely used.

CME-- Discharge Questions Answered in 2025
422. Finerenone restores fertility?
2026/03/02
Lin Z, et al. Antifibrotic drug finerenone restores fertility in premature ovarian insufficiency. Science 2026 Feb 5; 391:eadz4075. DOI: 10.1126/science.adz4075.   Premature ovarian insufficiency is usually one of those diagnoses that shuts the door on fertility: ovarian function is lost before age 40, mature follicles are scarce to nonexistent, and we have no reliable way to turn things back on. In most textbooks, that's the end of the story.   A group in Hong Kong is now asking a different question: what if the problem isn't just the follicles, but the neighborhood they live in? In aged mice, they found that the ovarian stroma becomes fibrotic and stiff, and that this mechanical stiffness itself seems to suppress follicle maturation. Loosen up the stroma, and previously dormant follicles begin to wake up.   To turn that concept into something clinically relevant, the team screened nearly 1,300 drugs that are already approved for other human uses, looking for agents that could activate follicles in mice. Ten made the cut. One of them, finerenone-an oral nonsteroidal mineralocorticoid receptor antagonist better known to nephrologists and cardiologists-also reduced collagen production in the ovarian stroma, effectively softening the tissue environment.   That observation led to a small, first-in-human trial. Fourteen women with POI-associated infertility received finerenone 20 mg twice weekly, with monthly ultrasound monitoring. Over 3 to 7 months, follicular development was seen in all participants, and eight produced mature oocytes. IVF was attempted when possible, and early embryos were obtained in three women; longer-term follow-up and pregnancy outcomes are still pending.   It's a fascinating mechanobiology story: instead of stimulating the follicle directly with gonadotropins or growth factors, the intervention targets the physical properties of the follicular niche. But there are important caveats. The study is tiny, uncontrolled, and POI is not an absolute guarantee of infertility-spontaneous ovulation and pregnancy do occasionally occur. Without a control group and without live-birth data, we cannot know yet how much of this signal represents true drug effect versus background noise.   For now, finerenone should stay firmly in the realm of clinical trials when it comes to fertility. But conceptually, this work opens a new front: treating infertility not just as an endocrine or genetic problem, but as a disease of tissue mechanics. If future studies confirm these findings, we may be looking at the beginnings of a paradigm shift in how we think about "irreversible" ovarian failure-and a new source of hope for patients who today are told their options are exhausted.
421. Scabies and DUKE criteria
2026/02/25
Stavropoulou E, et al. Reassessing the 2023 International Society for Cardiovascular Infectious Diseases Duke clinical criteria for infective endocarditis: Impact of excluding fever and updating diagnostic definitions. Clin Infect Dis 2025 Dec 31; [e-pub]. DOI: 10.1093/cid/ciaf737.    Big takeaways About 35% of patients truly had IE. Fever showed up in 80% of patients both with and without IE, so it did not help distinguish them. Dropping fever from the criteria actually made them better:   Sensitivity improved: 77% (no-fever) vs 74% (standard). Specificity improved a lot: 80% vs 49%. "Possible IE" shrank from 39% to 17%, meaning fewer gray-zone cases. Only 0.4% of patients without IE were incorrectly labeled as having IE.  Both are widely used and both can work for regular (non-crusted) scabies.   The SCRATCH trial: who won? In the SCRATCH trial from France, researchers treated about 1000 people in 300 households with confirmed scabies. Each household was randomized to:   Whole-body 5% permethrin cream on days 0 and 10, or Oral ivermectin (weight-based) on days 0 and 10. They then checked who was cured at day 28.   Here's what they found: Household cure rates Permethrin: 88% cured Ivermectin: 72% cured Translation: For every 6 households treated with permethrin instead of ivermectin, one extra household was fully cured (NNT  6).   Index (main) patient cure rates Permethrin: 92% Ivermectin: 77% That's one extra person cured for about every 7 treated with permethrin instead of ivermectin (NNT  7).   Side effect Skin irritation-type reactions: 14% with permethrin vs 10% with ivermectin. So permethrin wins on cure, with a small trade-off in local skin reactions.
