Experts evaluated presurgical short-term endocrine therapy (preSTE) in 269 postmenopausal HR+ breast cancer patients. Median preSTE duration was 39 days. It significantly reduced tumor size and Ki67 expression. Patients with a preoperative endocrine prognostic index (PEPI) score ≥ 4 exhibited worse disease-free and overall survival. The study concludes that preSTE is effective, and Ki67 levels and PEPI scores are useful prognostic predictors.

A recent study highlights the utility of two-dimensional speckle tracking echocardiography in assessing right atrial mechanics in OSAHS. Progressive reductions in reservoir and conduit strain, coupled with elevated contraction strain, signal early right heart remodeling correlated with apnea severity.

A premature neonate developed upper limb compartment syndrome after uterine rupture extruded the arm through a scar defect. Conservative management with continuous monitoring yielded complete functional recovery and normal limb growth at 10-year follow-up, highlighting non-operative safety in selected cases.
