A Chest Story Sharp as a Knife

In a case that could make even seasoned surgeons do a double-take, clinicians at Muhimbili National Hospital discovered a full knife blade that had been quietly camped out in a 44-year-old man’s chest for 8 years. The patient arrived not with dramatic trauma symptoms, but with a stubborn, foul-smelling sinus below the right nipple. He had previously been treated for multiple stab wounds with only primary first aid. Imaging finally revealed the long-retired blade stretching from the right scapula region to the anterior chest, complete with healed rib and scapular fractures and a chronic loculated hematoma. A posterolateral thoracotomy uncovered many adhesions, pus, necrotic tissue, and the well-traveled foreign body lodged in the middle lobe. After extraction, necrosectomy, irrigation, and chest tube drainage, the patient recovered uneventfully and strolled through his follow-up. This case is a stark reminder that in trauma care, even the smallest clue can cue the unexpected twist.

A migraine study from Massachusetts General Hospital essentially asked: What happens when life gets weird? In this cohort of 109 adults with migraine (median age, 35 years; 93.5% female), participants logged their sleep, stress, mood, meals, and environmental exposures twice daily for 28 days—and headaches on nearly 30% of tracked days. Researchers converted each person’s daily life chaos into a surprisal score, measured in bits, capturing how unusual a given day was compared with each person's norm. Higher surprisal reliably signaled higher migraine risk within 12 and 24 hours, with stronger effects at 24 hours than at 12 hours. When the prior day was calm, a sudden bout of unpredictability sharply boosted risk; when life was already off-balance, added chaos mattered less. The findings suggest that, instead of hunting down single triggers, digital tools could flag when a day is simply off-script—a personalized early warning for migraine.

In this nationally representative NHANES analysis of 43,276 US adults followed for a median 8.7 years, investigators asked a simple clinic-friendly question: how many cups of tea a day might buy you more time on the planet? The longevity sweet spot for tea drinkers landed at about 3 to 5 cups a day.  At age 50, that habit translated into an extra 2.2 years of life — 32.9 vs 30.7 years for nondrinkers. Not bad for something you can brew in a mug. Other intake levels didn’t move the needle much, and 5 or more cups a day even trended the wrong way. The magic held mostly for women and White adults, while benefits were less obvious in men and in Black and Hispanic groups. Unsweetened tea outperformed sugary tea, and higher sugar use clustered in groups with shorter life expectancy. Both black and other teas (including good old green) looked promising, though observational limits mean this is more “sip happily” than “prescribe immediately.”

In a “California sober” twist, a Brown University addiction research team ran a double-blind randomized crossover trial in 138 adults (mean age 26 years) who drank heavily and used cannabis at least twice weekly. On three separate bar nights at the lab, participants smoked cannabis with 7.2% THC, 3.1% THC, or placebo before facing alcohol cues and an alcohol self-administration task. THC did not change composite alcohol craving scores, but the 7.2% dose slightly lowered ratings of immediate urge for alcohol. The real punchline was in consumption: compared with placebo, participants drank about 19% less alcohol after 3.1% THC and 27% less after 7.2% THC, and the higher THC dose stretched time to first drink from about 22.5 to 33.4 minutes. Everyone still drank, just less. The investigators emphasized that, despite these intriguing acute effects, it is far too early to recommend cannabis as a harm-reduction strategy for alcohol use disorder.

E. coli appears to moonlight as a genome contortionist, according to researchers at Penn State. When the T2 phage barges in, the bacterium flips a 1,797-bp segment of cryptic prophage DNA called the e14-P segment, powered by the serine recombinase PinQ. That flip instantly assembles a new chimeric protein, StfE2, which blocks the phage from grabbing its usual outer-membrane receptors, FadL and OmpF. With PinQ active, T2 plaque formation dropped about tenfold, host survival jumped roughly 400-fold, and cells essentially became phage-proof. Deleting PinQ had the opposite effect, making E. coli markedly vulnerable. Even T2 tried to adapt, mutating its gp38 adhesion protein to sneak past the new barricade. Once the phage threat vanished, E. coli calmly flipped the segment back, avoiding the metabolic cost of staying on high alert. It’s a genomic escape room—rigged by bacteria and sprung only when phages attack.
