Background: Systemic inflammation and immune-mediated diseases have been associated with ischemic heart disease in addition to traditional risk factors. In this study, we investigate associations between inflammatory bowel disease (IBD) and acute cardiovascular events.
Methods: An observational study where patient data were extracted from our health system patient pool of 3 917 894. Propensity scores were calculated for all 15 292 patients (0.39%) with IBD to assemble a 1:1 matched cohort balanced for age, gender, race and known cardiovascular risk factors including hypertension, hyperlipidemia, diabetes mellitus and smoking (current and former). Secondary analyses were performed independently for 6658 patients with ulcerative colitis and 9406 patients with Crohn's disease. ICD-9 and ICD-10 codes were used to identify cardiovascular risk factors and outcomes.
Results: Matched patients (n = 30 584) had a mean age of 51 years, with 58% being women, and 63% Caucasian. During the median follow-up of 4.4 years, all-cause mortality was observed in 1.7 versus 1.2% of patients from IBD and non-IBD groups, respectively [hazard ratio, 1.31; 95% confidence interval (CI), 1.08-1.58; P = 0.005]. Combined outcome for myocardial infarction or cardiovascular mortality was noted in 2.3 and 2.1% from IBD and non-IBD groups, respectively (hazard ratio, 1.04; 95% CI, 0.90-1.21; P = 0.588), while hazard ratios for cardiovascular mortality, myocardial infarction and unstable angina were 1.04 (0.74-1.47; P = 0.833), 1.05 (0.89-1.23; P = 0.591) and 1.10 (0.83-1.46; P = 0.524), respectively.
Conclusions: Among patients with IBD, incidence of acute coronary events did not show a statistically significant difference when compared to the matched cohort.

Purpose: In early-stage breast cancer, steatotic liver disease (SLD) is associated with increased recurrence, cardiovascular events, and non-cancer death. Endocrine therapy (ET) increases the risk of SLD. The impact of cyclin-dependent kinases 4/6 inhibitors (CDK4/6i) on SLD and prognostic association in metastatic breast cancer is unknown.
The Gram-positive cocci Staphylococcus aureus, Streptococcus spp., and Enterococcus spp. are the most frequent causative organisms of bloodstream infections and infective endocarditis.
Background: CD4+ T cells expressing α4β7 are optimal targets for HIV infections, with higher pre-HIV α4β7hi expression linked to increased HIV acquisition and progression in South African women. However, similar associations were not observed in men who have sex with men (MSM) or people who inject drugs (PWID) in the Americas, indicating need for further research.
Methods: This retrospective case-control study enrolled heterosexual men and women from South Africa (HIV Vaccine Trials Network; HVTN 503) and East Africa (Partners Pre-Exposure Prophylaxis/Couples' Observational Study; PP/COS), quantifying α4β7 expression on CD4+ T cells as a predictor of subsequent HIV risk using flow cytometry analyses.

Breast cancer (BC) is a prevalent malignant tumor that poses a significant health risk to women. The complexity of basic BC research and clinical treatment is influenced by multiple factors, including age, fertility, hormone metabolism, molecular subtypes, and tumor grading and staging. Traditional in vitro models often fall short of meeting modern research demands, whereas organoids-an emerging 3D primary culture technology-offer a unique platform that better replicates the tumor microenvironment (TME).
