Objective: To assess whether resuming positive airway pressure (PAP) on postoperative day 0 or 1 is associated with sinonasal outcomes after functional endoscop
A prospective controlled study included 100 adults undergoing functional endoscopic sinus surgery at 4 US academic centers; 49 patients with obstructive sleep apnea resumed PAP on postoperative day 0
After adjustment for clinical and surgical factors, early PAP resumption was not significantly associated with worse endoscopic scores at either postoperative assessment.
Sinonasal symptoms and sleep quality improved in both groups, with no significant adjusted differences associated with early PAP resumption.
Epistaxis severity and need for medical management did not differ significantly between groups, and no PAP-related complications were reported.
The nonrandomized study had a small sample, baseline group differences, self-reported PAP adherence, and exclusions that limit assessment of uncommon complications and generalizability.

Objective: The article reports the November 12 shooting at and outside VIDA Fitness in Washington, DC, the police response, and condominium complaints described
Federal law enforcement officials identified Matt Lambert, MD, as the suspected gunman in a November 12 shooting at VIDA Fitness in Washington, DC.
One person was killed and 4 others were injured and transported to area hospitals.
Police found Lambert dead in an apartment above the gym from an apparent self-inflicted gunshot wound.
Investigators reportedly examined a possible conflict involving Lambert and his condominium association, but authorities had not established a motive.
Posts from an apparent account belonging to Lambert described building problems, but did not establish that the complaints were substantiated or connected to the shooting.
Objective: To compare short-term effects of a USB-powered warm compress and a disposable self-heating mask in adults with meibomian gland dysfunction. Approach:
In a randomized crossover trial of 15 adults with meibomian gland dysfunction, participants used each warm-compress device for 10 minutes daily over 5 days, with a 2-week washout.
By Day 5, mean tear breakup time increased from 7.2 to 9.5 seconds with the USB-powered compress and from 7.3 to 7.9 seconds with the disposable mask.
Mean tear meniscus height increased from 0.16 to 0.28 mm with the USB-powered compress and from 0.16 to 0.22 mm with the disposable mask; the between-device difference was statistically significant.
SPEED symptom scores improved modestly with both devices, with no statistically significant between-device difference; visual acuity remained stable and no adverse events were reported.
The small, single-center trial had short treatment periods and supervised sessions, and the authors said whether the measured improvements yield lasting patient benefits remains uncertain.

Objective: Assess whether Raman spectroscopy combined with machine learning can estimate multiple maple syrup quality attributes from one analytical workflow. A
Researchers analyzed 721 untreated maple syrup samples with 785-nm Raman spectroscopy, collecting 21,630 spectra for machine-learning analysis.
Convolutional neural networks classified golden and very dark syrups with 91% and 92% accuracy, respectively, but accuracy was lower for amber and dark grades.
Flavor-classification accuracy was 83% for syrups without detectable defects and 78% for syrups with the late-season “buddy” defect.
Raman fluorescence background intensity increased as syrup darkened and supported color-grade estimates with 81% to 94% accuracy.
A sucrose-standard model yielded an R² of 0.87 and a 2.2% root mean squared error, but syrup estimates were sucrose equivalents, not validated sugar concentrations.
Objective: To develop a method for mapping local pH changes in 3D breast cancer models after different forms of cellular stress. Approach: Sensor and model: Res
Researchers integrated pH-responsive surface-enhanced Raman scattering nanotags into breast cancer cells on a 3D-printed hydrogel scaffold.
The nanotags used polymer-coated gold nanostars functionalized with 4-mercaptobenzoic acid to measure local pH through changes in Raman spectral bands.
After chemotherapy, surfactant exposure, or plasmonic heating, the sensors detected pH increases, with timing varying from minutes to days.
Independent cytotoxicity testing linked the pH increases to cell membrane damage, and Raman maps captured changes at subcellular resolution across millimeter-scale regions.
The authors identified calibration stability, sensor variation, nanotag effects, and performance in more complex tissue models as areas for future assessment.

Objective: The article summarizes a case of Takotsubo cardiomyopathy following influenza A and research on frozen hair follicles, language in dreams and mind-wa
A 67-year-old woman developed Takotsubo cardiomyopathy 2 weeks after testing positive for influenza A.
Despite ECG changes, elevated troponin I, and a left ventricular ejection fraction of 30%, catheterization showed nonobstructive coronary artery disease.
Left ventriculography showed severe apical hypokinesis with hyperdynamic basal segments, characteristic of Takotsubo cardiomyopathy.
She initially received aspirin, clopidogrel, and intravenous heparin, then was discharged on a statin and an angiotensin-converting enzyme inhibitor with prompt cardiology follow-up.
Potential Takotsubo cardiomyopathy complications include heart failure, cardiogenic shock, arrhythmias, and thrombosis.
Objective: To synthesize mortality and key safety outcomes from the CloCeBa and SNAP randomized trials comparing cefazolin with antistaphylococcal penicillins f
The Bayesian meta-analysis combined 2 randomized trials involving 1579 evaluable patients with MSSA bacteremia across 9 countries and 112 hospitals.
Cefazolin had an odds ratio for 90-day mortality of 0.84 (95% credible interval, 0.59-1.28), with a 95.5% probability of noninferiority within the prespecified margin.
The probability that cefazolin reduced 90-day mortality compared with cloxacillin or flucloxacillin was 81.0%.
Cefazolin was superior for treatment discontinuation due to adverse events, with a 99.9% probability, and for acute kidney injury, with a 98.4% probability.
The analysis included only 2 trials, and limited subgroup enrollment precluded meaningful inferences about endocarditis and S aureus type A blaZ gene carriers.
