Extra MRI did not improve Long COVID fatigue in a large care-pathway trial
Fatigue improved across all groups receiving specialist care, but adding multi-organ MRI produced no measurable advantage at 12 weeks.

Health & Medicine Moderate evidence
Survodutide reduced weight more than placebo in a 76-week obesity trial
The drug produced double-digit average weight loss, while gastrointestinal side effects were frequent and discontinuation matters.
Health & Medicine Moderate evidence
Pulsed-field ablation beat antiarrhythmic drugs as initial therapy in persistent AF
Rhythm-control success was higher at one year, but the device procedure still carried risks and industry funding deserves attention.
Health & Medicine Moderate evidence
Atrial-appendage closure matched anticoagulants on a composite outcome in one trial
The device was noninferior for cardiovascular death, stroke or embolism and reduced non-procedural bleeding over three years.
Health & Medicine Moderate evidence
Intensive physician role-play training improved six-month diabetes control
Patients of trained physicians reached HbA1c targets more often, but the intervention tested implementation—not a new diabetes treatment.
Health & Medicine Moderate evidence
Automated oxygen titration kept hospitalized adults in the target range longer
The system improved oxygen-range control compared with usual care; clinical outcomes and safe implementation still need evaluation.
Health & Medicine Moderate evidence
Two common anesthesia strategies produced nearly identical days at home after surgery
Intravenous anesthesia did not improve the primary recovery outcome, though some next-day discomforts were less frequent.
Health & Medicine Preliminary evidence
A selective sodium-channel blocker reduced pain after abdominoplasty in phase 2
LTG-001 targets peripheral pain signaling without being an opioid, but comparative effectiveness and broader safety remain unsettled.
Health & Medicine Moderate evidence
Better measured fitness tracked with lower mortality in older adults
Balance, agility, lower-body strength and cardiorespiratory fitness were associated with survival, but the observational design cannot prove that testing or training caused it.
Health & Medicine Hypothesis / modeling
CDC assessment found the immediate U.S. risk from the Bundibugyo Ebola outbreak was low
A federal risk assessment combined outbreak reports, travel patterns and response capacity to judge the near-term likelihood of U.S. importation and spread.
Health & Medicine Hypothesis / modeling
Modeled Ebola scenarios show how early response can change outbreak size
CDC researchers compared plausible transmission and intervention scenarios to estimate how timing and control strength could affect an Ebola outbreak.
Health & Medicine Preclinical research
A targeted immune strategy reduced transplant rejection signals in preclinical tests
NIH-highlighted research tested a way to quiet immune cells involved in organ rejection while trying to preserve broader immune function.
Health & Medicine Moderate evidence
Wear and tear changed measurable PFAS levels in firefighter hoods and gloves
NIST testing found that use-related wear can alter how fluorinated chemicals are measured in protective gear, complicating exposure and replacement decisions.
Health & Medicine Preclinical research
Stress-linked changes in gut viruses may help tumors evade immune attack
A Cornell-led study connected stress, bacteriophages in the gut and weaker antitumor immunity in experimental systems.
Health & Medicine Moderate evidence
An Alzheimer’s blood test performed well in patients with cognitive symptoms
The result is promising for diagnosis—but it was not a general-population screening test, and accuracy is not the same as improved patient outcomes.
