Excess-Weight Metrics Misrepresent Weight Loss and No Metric Predicts the Metabolic Outcome After Metabolic and Bariatric Surgery

This study analyzing over 180,000 patients demonstrates that common excess-weight metrics misrepresent actual weight loss due to baseline BMI dependence and fail to predict metabolic outcomes after bariatric surgery, suggesting that direct measurement of glycemic response should be prioritized for patients with type 2 diabetes.

Diminishing Protective Effects of EVAR on Postoperative Delirium Beyond Age 80: A Proposal for Tailored Prevention Strategies

While endovascular aneurysm repair (EVAR) significantly reduces the risk of postoperative delirium compared to open surgical repair in patients under 80 by mitigating surgical stress, this protective advantage diminishes in octogenarians due to overwhelming intrinsic vulnerability, necessitating aggressive geriatric co-management rather than relying solely on minimally invasive techniques.

Periodontitis and periodontal inflamed surface area in context of plant-based dietary patterns: Insights from the Hamburg City Health Study

In a large population-based study, higher adherence to healthful plant-based dietary patterns was significantly associated with reduced odds of severe periodontitis and lower periodontal inflamed surface area, while unhealthful plant-based patterns showed the opposite effect, with systemic inflammation partially mediating these relationships.

Sustained-release alphitolic acid-loaded hydrogel attenuates intervertebral disc degeneration through regulation of the MIF-SERPINE1-PI3K-Akt/NF-κB axis

This study identifies the MIF-SERPINE1-PI3K-Akt/NF-κB axis as a critical driver of intervertebral disc degeneration and demonstrates that an injectable, sustained-release hydrogel loaded with the MIF antagonist alphitolic acid effectively blocks this pathway to attenuate inflammation and restore extracellular matrix homeostasis in a rat model.

Characterizing the thrombotic spectrum and clinical phenotypes of tranexamic acid-associated adverse events: a pharmacovigilance study based on the FAERS database

This pharmacovigilance study utilizing the FAERS database characterizes the heterogeneous clinical phenotypes of tranexamic acid-associated thrombotic events, revealing that venous thromboembolism is the most frequent and severe type while cerebrovascular thrombosis disproportionately affects young females, thereby highlighting the need for enhanced risk stratification in specific high-risk populations.

Non-febrile headache burden among secondary school students in Bukavu, Democratic Republic of Congo: prevalence, clinical phenotype, and sex differences

This 2019 cross-sectional study of 400 secondary school students in Bukavu, DRC, reveals a high 6-month prevalence of non-febrile headaches (67.5%), predominantly migraines, which significantly impact academic performance and show marked sex differences with females experiencing more frequent and severe symptoms, highlighting a critical unmet need for screening and preventive care in this low-resource setting.

Community participation and belonging during rural nursing placements in Queensland: A cross-sectional study

This cross-sectional study of 153 undergraduate nursing students in rural Queensland found that while community interaction increased during placements, a sense of belonging was more strongly associated with the breadth of active community participation and repeated rural experiences than with mere exposure or interaction frequency.

Prior Cervical Cancer Screening, Social Determinants of Health, and HIV Status Among Patients at the Cancer Disease Hospital, Zambia

This prospective study of 464 cervical cancer patients in Zambia found that prior screening was significantly associated with younger age, higher socioeconomic status (lower SDOH scores), and HIV-positive status, highlighting the critical role of social determinants and HIV care integration in screening uptake.

Transcriptomic, epigenetic, and immune-infiltration analyses to identify molecular drivers associated with clinical outcomes in ovarian cancer

This study identifies SLC7A11 as an epigenetically regulated hub gene that links ferroptosis to immune remodeling in ovarian cancer, where its high expression correlates with macrophage enrichment, CD8+ T cell depletion, and poor patient survival, ultimately supporting the development of a robust prognostic nomogram.
