Context: The outcomes related to cardiovascular risk (CVR) in patients with the nonclassical form of congenital adrenal hyperplasia (NCAH) are unknown, especially those related to therapeutic options, including low doses of glucocorticoids or oral contraceptive pills.
Objectives: To analyze CVR by markers of atherosclerosis in females with the nonclassical form according to therapeutic options.
Design And Setting: A cross-sectional study at a tertiary center.
Patients And Methods: Forty-seven females with NCAH (33.4 ± 10 years) were subdivided into group 1 (G1) (n = 28) treated with dexamethasone (0.14 ± 0.05 mg/m2/day), group 2 (G2) (n = 19) treated with oral contraceptive pills, and group 3 (G3) (30 matched controls). CVR was analyzed through serum lipids, the Homeostatic Model Assessment for Insulin Resistance (HOMA-IR), inflammatory cytokines levels, and quantitative image evaluations [pulse wave velocity (PWV), endothelial function by flow-mediated dilatation (FMD), carotid intima media thickness (CIMT), and visceral fat (VAT) by abdominal tomography].
Results: There were no statistically significant differences in BMI, HOMA-IR, high-density lipoprotein-cholesterol, or triglyceride levels among groups (P > .05). Serum interleukin 6 (IL-6) levels were higher in G1 than in G2 (P = .048), and interleukin 8 (IL-8) levels were higher in G1 than in G2/3 (P = .008). There were no statistically significant differences in VAT, PWV, FMD, or CIMT among groups (P > .05). In multivariable regression analysis, there was no statistically significant association between glucocorticoid dose and evaluated outcomes.
Conclusion: Adult females with NCAH did not show increased CVR using methodologies for detection of precocious atherosclerosis. Although patients receiving dexamethasone therapy had increased IL-6 and IL-8 levels, these data were not associated with radiological markers of atherosclerosis. Our cohort was composed of young adults and should be reevaluated in a long-term follow-up.

Background: Adherence to self-care behaviors can prevent or delay adverse outcomes associated with cardiovascular disease (CVD). Sex and socioculturally constructed gender might impact individuals' ability to adhere to healthy lifestyles.
Objective: The aim of this study was to systematically identify, evaluate, and synthesize the literature on the influence of sex and gender on adherence to self-care behaviors for CVD risk management in the global context.
Sex differences in the association between composite dietary antioxidant index and hyperlipidemia: Insights from NHANES.

Background: Previous studies have shown that both the composite dietary antioxidant index (CDAI) and sex are strongly associated with a variety of cardiovascular diseases, but sex differences between CDAI and hyperlipidemia are unknown.
Objective: This study utilized data from the National Health and Nutrition Examination Survey (NHANES) to investigate the sex differences between CDAI and hyperlipidemia.
Method: We calculated the CDAI of the six dietary antioxidants using data from NHANES, explored the relationship between CDAI and the prevalence of hyperlipidemia using multivariate logistic regression analysis, and analyzed for potential nonlinear associations using restricted cubic spline.
The efficacy of Lacticaseibacillus paracasei MSMC39-1 and Bifidobacterium animalis TA-1 probiotics in modulating gut microbiota and reducing the risk of the characteristics of metabolic syndrome: A randomized, double-blinded, placebo-controlled study.

Modern treatment, a healthy diet, and physical activity routines lower the risk factors for metabolic syndrome; however, this condition is associated with all-cause and cardiovascular mortality worldwide. This investigation involved a randomized controlled trial, double-blind, parallel study. Fifty-eight participants with risk factors of metabolic syndrome according to the inclusion criteria were randomized into two groups and given probiotics (Lacticaseibacillus paracasei MSMC39-1 and Bifidobacterium animalis TA-1) (n = 31) or a placebo (n = 27).

Background: Cardiac magnetic resonance (CMR) is essential for diagnosing cardiomyopathy, serving as the gold standard for assessing heart chamber volumes and tissue characterization. Hemodynamic forces (HDF) analysis, a novel approach using standard cine CMR images, estimates energy exchange between the left ventricular (LV) wall and blood. While prior research has focused on peak or mean longitudinal HDF values, this study aims to investigate whether unsupervised clustering of HDF curves can identify clinically significant patterns and stratify cardiovascular risk in non-ischemic LV cardiomyopathy (NILVC).
