Background: The aim of this study was to determine the factors affecting postoperative mortality in patients older than 65 years of age undergoing surgery for hip fracture.
Methods: A total of 308 patients (219 males and 89 females) were included into the study. Spinal-epidural anaesthesia was administered in 203 patients and general anaesthesia in 105 patients. In the evaluation of the patients regarding ASA, two groups were determined ASA 1-2 and ASA 3-4. Systemic diseases present in the patients were determined preoperatively.
Results: Seventy-seven (25%) of the total 308 patients died. In addition, patients with preoperative cardiac disease, patients on whom general anaesthesia was administered, patients in the ASA 3-4 group, and age were found to be significantly higher in mortality. When logistic regression analysis was performed for these four efficient factors, age, general anaesthesia, presence of cardiac disease were effective in mortality. However, ASA score changed depending on the age and cardiac disease.
Conclusion: In case of presence of multiple risk factors, it is necessary to determine which factor is, in fact, more effective. Age, ASA score, type of anaesthesia, and presence of cardiac disease are effective in mortality. However, ASA score affects mortality depending on the cardiac disease and age.

Institute of Ophthalmology, School of Medicine, Jinan University, Guangzhou, China.
Purpose: To investigate the therapeutic efficacy of BEZ235, a dual PI3K/mTOR inhibitor, in suppressing pathological neovascularization in an oxygen-induced retinopathy (OIR) mouse model and explore the role of cyclin D1 in endothelial cell cycle regulation.
Methods: Single-cell RNA sequencing was performed to analyze gene expression and cell-cycle alterations in retinal endothelial cells under normoxic and OIR conditions. The effects of BEZ235 on human umbilical vein endothelial cells (HUVECs) and human retinal microvascular endothelial cells (HRMECs) were evaluated by assessing cell viability, cell-cycle progression, proliferation, migration, and tube formation.
Corticosteroids in Cardiogenic Shock: A Retrospective Analysis of the Medical Information Mart for Intensive Care-IV Database.
Crit Care Explor

Division of Critical Care Medicine, Department of Medicine, McMaster University, Hamilton, ON, Canada.
Importance: While corticosteroid administration in septic shock has been shown to result in faster shock reversal and lower short-term mortality, the role of corticosteroids in the management of cardiogenic shock (CS) remains unexplored.
Objectives: Determine the impact of corticosteroid administration on 90-day mortality (primary outcome) in patients admitted to a critical care unit with CS.
Design, Setting, And Participants: In this retrospective cohort study, we used the critical care database of Medical Information Mart for Intensive Care-IV, and included all adult patients diagnosed with CS excluding repeated admissions, patients with adrenal insufficiency, those receiving baseline corticosteroids, and those requiring extracorporeal life support.

Background: 4-(4-Cyanophenyl)-2-(2-cyclopentylidenehydrazinyl)thiazole (remodelin) is a potent N-acetyltransferase 10 (NAT10) inhibitor. This compound inhibits tumors and weakens tumor resistance to antitumor drugs. Moreover, remodelin has been found to enhance healthspan in an animal model of the human accelerated ageing syndrome.

Air pollution is a global environmental health hazard associated with elevated cardiovascular morbidity and mortality. Emerging evidence suggests that exposure to various air pollutants, specifically particulate matter (PM), ultrafine particulate matter (UFPM), and diesel exhaust particles, may exacerbate myocardial ischemia-reperfusion (I/R) injury. PM exposure can directly impair cardiomyocyte survival under ischemic conditions by inducing inflammation, oxidative stress, apoptosis, and dysregulation of non-coding RNAs.

Approximately 1% of all live births in the USA are affected by congenital heart disease (CHD), the leading cause of congenital defect-related illness and infant death. Although technological innovations have improved CHD diagnosis in utero, variation among fetal cardiac counseling practices persists. Our study aims to evaluate physician counseling content based on cardiac defect complexity.
