The objective of this study was to investigate the relationship between alterations in the elasticity of the temporal and the renal arteries and the grade of arteriopathy, using the pulsatility index in type II diabetic patients and healthy volunteers. All individuals were divided into groups. Group A consisted of 15 patients without risk factors (hyperlipidemia, hypertension, obesity, and smoking) and had well-controlled diabetes mellitus as demonstrated by normal values of HbA1c. Group B had 20 patients with two risk factors (hyperlipidemia and hypertension) and normal HbA1c. Group C (25 patients) had four risk factors and high values of HbA1c, and group D consisted of 20 healthy individuals. All patients were examined by use of color Doppler ultrasonography. Pulsatility index values were measured in the temporal and renal arteries. Pulsatility indices of temporal arteries were higher in group C than in groups A and B, whereas for the renal arteries, no significant difference was detected between the four groups. In our study there seems to be strong correlation between increased values of pulsatility index, mainly in the temporal arteries, and grade of arteriopathy in type II diabetic patients.

Background: Patients with end-stage kidney disease (ESKD) are at high risk for coronary artery disease. We investigate the trends and outcomes of percutaneous coronary intervention (PCI) for stable ischemic heart disease (SIHD) in patients with ESKD.
Methods: We utilized the United States Renal Data System [2010-2018] to include adult patients with ESKD on dialysis for at least 3 months who underwent PCI for SIHD.
Predictors of Mortality among End-Stage Renal Disease Patients with COVID-19 Admitted in a Philippine Tertiary Government Hospital: A Retrospective Cohort Study.

Background And Objective: Several studies have examined the predictors of mortality among COVID-19-infected patients; however, to date, few published studies focused on end-stage renal disease patients. The present study, therefore, aims to determine the predictors of in-hospital mortality among end-stage renal disease patients with COVID-19 admitted to a Philippine tertiary hospital.
Methods: The researcher utilized a retrospective cohort design.
The Role of Intravenous Selexipag in Managing PAH and Bridging Gaps in Oral Treatment: A Narrative Review.

Pulmonary arterial hypertension (PAH) is a rare and potentially fatal condition characterized by progressive increases in blood pressure in the arteries of the lungs. Oral selexipag, approved by the Food and Drug Administration (FDA) in 2015 for the treatment of PAH, targets prostacyclin receptors on pulmonary arterial vascular smooth muscle and endothelial cells to improve blood flow through the lungs and reduce pulmonary vascular resistance. Oral selexipag is effective, but may be discontinued due to factors like side effects, emergency conditions, or inability to take oral medication, potentially leading to severe adverse events, such as rebound pulmonary hypertension and right heart failure.

Transplant renal artery stenosis (TRAS) is a serious complication of renal transplantation, with its prevalence and associated factors remaining inconclusive. The aim of this study was to assess the global prevalence and risk factors associated with TRAS incidence in renal transplant recipients. We conducted a meta-analysis by collecting data on the prevalence and factors associated with TRAS from articles in Scopus, Embase, and PubMed.
