Effects of sodium-glucose cotransporter-2 inhibitors on nutritional status in heart failure with reduced ejection fraction.
This study aimed to evaluate the effects of sodium-glucose cotransporter-2 inhibitors on nutritional status in patients with heart failure with reduced ejection fraction. ⋯ In patients with heart failure with reduced ejection fraction who are symptomatic despite optimal medical treatment, the addition of an sodium-glucose cotransporter-2 inhibitor to treatment can significantly improve both the nutritional and functional statuses.

Evaluation of the cardio-ankle vascular index in COVID-19 patients.
This study aimed to investigate the relationship and prognostic significance of cardio-ankle vascular index, which is a measure of arterial stiffness that can lead to endothelial dysfunction and poor cardiovascular issues in COVID-19 patients, with COVID-19. ⋯ The right-cardio-ankle vascular index and left-cardio-ankle vascular index values increased in COVID-19 patients in our study, and this was thought to be prognostically significant.

Effect of anesthesia type on outcome measures in cesarean section in the presence of fetal macrosomia.
The aim of this study was to compare the effects of general and spinal anesthesia on maternal and neonatal outcomes during cesarean section in pregnancies with macrosomia. ⋯ Apgar scores of <7 at the first and fifth minutes are higher in macrosomic neonates who received general anesthesia than in neonates who received spinal anesthesia. Performing cesarean section under general anesthesia in mothers of macrosomic neonates results in a greater decrease in hematocrit value and a greater need for blood transfusion than under spinal anesthesia.

The relation of dermcidin with insulin resistance and inflammation in women with polycystic ovary syndrome.
Polycystic ovary syndrome is the most common endocrinopathy among women of reproductive age. Polycystic ovary syndrome is a metabolic disorder associated with insulin resistance and subclinical inflammation. Dermcidin, an antimicrobial peptide, involves in insulin resistance and inflammatory processes. Dermcidin suppresses the secretion of insulin production from the liver/pancreas and also increases insulin resistance. We aimed to discover whether dermcidin levels were altered in polycystic ovary syndrome women compared to controls and determine the link of dermcidin with hormonal-metabolic parameters in polycystic ovary syndrome women. ⋯ Increased dermcidin levels were associated with insulin resistance and inflammation in polycystic ovary syndrome women, suggesting that dermcidin may play a role in the pathophysiology of polycystic ovary syndrome.

Association between ventricular premature contraction burden and ventricular repolarization duration.
Premature ventricular contraction is generally known as benign in the absence of structural heart disease; however, premature ventricular contraction-induced left ventricular systolic dysfunction or ventricular arrhythmias are defined in some cases. Ventricular repolarization duration differs between myocardial cells, which causes myocardial electrical heterogeneity and is thought to be responsible for ventricular arrhythmias. In our study, we aimed to evaluate the association of ventricular repolarization parameters including Tp-Te interval, Tp-Te/QT ratio, and QRS-T angle with premature ventricular contraction frequency in patients with premature ventricular contraction burden. ⋯ Increased Tp-Te interval and widened QRS-T angle are associated with ventricular arrhythmias and might be used for the prediction of premature ventricular contraction burden in patients with premature ventricular contraction in electrocardiography in the absence of 24-h Holter monitoring.
