In a propensity-matched study of an Asian population, kinematic alignment in primary total knee arthroplasty demonstrated comparable or superior two-year functional outcomes and patient satisfaction relative to mechanical alignment, with equivalent safety and revision-free survival rates.
This prospective observational study found that while microplastics are universally present in the bronchoalveolar lavage fluid of both newly diagnosed lung cancer patients and controls, their densities are comparable between the two groups, suggesting that these particles reflect general environmental inhalation rather than serving as a specific indicator of malignancy.
This study combines a single-center cohort analysis and a meta-analysis to reveal that the risk of stroke-associated pneumonia following intracerebral hemorrhage is significantly higher than previously reported, with evidence suggesting a concerning upward trend in incidence since 2019.
In a large nationwide Korean cohort study, initiating SGLT2 inhibitors as second-line therapy for type 2 diabetes was associated with a significantly lower 180-day risk of acute kidney injury compared to sulfonylureas, a protective effect that persisted in patients with heart failure but was attenuated among those with pre-existing chronic kidney disease.
This retrospective cohort study of 2,242 cardiac surgery patients demonstrates that postoperative vasopressor-inotropic requirements and intraoperative hypotension serve as significant, partially modifiable mediators linking preoperative pulmonary hypertension to an increased risk of acute kidney injury.
This cross-sectional analysis of the Beichen Eye Study involving 4,748 participants aged over 50 found that a higher triglyceride-to-HDL cholesterol ratio and lower triglyceride levels were associated with a reduced prevalence of age-related macular degeneration, while HDL cholesterol alone showed no independent association.
This study utilizes 3D-CT to characterize the anatomical variations of the first jejunal trunk (FJT) relative to the superior mesenteric artery, revealing that the Ventral type exhibits more cranial venous confluence and a greater relative venous contribution than the Dorsal type, which has significant implications for preoperative planning in pancreaticoduodenectomy.
This study demonstrates the technical feasibility of a SwinUNETR-based deep learning pipeline for automated whole-body lesion segmentation and Osteo-Medullary Invasion Score (OMIS) computation on [68Ga]Ga-DOTA-TOC PET/CT, achieving performance comparable to expert inter-observer agreement and offering a reproducible tool for pre-PRRT risk stratification in neuroendocrine tumor patients.
This case report describes the successful reversal of tachycardia-induced cardiomyopathy in a 4.5-month-old infant with focal atrial tachycardia through the prompt initiation of flecainide therapy, which restored sinus rhythm and led to the complete recovery of ventricular function and clinical status after initial rate-control strategies failed.
This study developed and internally validated a simple four-variable model incorporating albumin, alanine aminotransferase, prothrombin time activity, and splenomegaly that demonstrates superior predictive accuracy for high-risk varices in patients with virally suppressed HBV-related cirrhosis compared to established non-invasive scores.
