Cardiometabolic factors and vitamin D deficiency in pediatric patients with chronic kidney disease.

Background: Patients with chronic kidney disease (CKD) are at increased risk for cardiovascular disease. Up to 80% of patients with CKD may exhibit inadequate vitamin D (VD) levels, which have been linked to the presence of cardiometabolic factors (CFs) in the adult population. However, research on this association in the pediatric population is limited.

Liver enzyme levels in adolescents with obesity and insulin resistance: a propensity score matching analysis.

Background: Elevated liver enzyme levels have been associated with metabolic syndrome in both obese and non-obese pediatric populations. This study aims to compare the serum liver enzyme levels in obese adolescents with and without insulin resistance (IR).

Methods: A cross-sectional analysis was conducted involving obese adolescents aged 10-18.

Factors associated with vitamin D deficiency in health care workers exposed to SARS-CoV-2: a cross-sectional study.

Introduction: Globally, up to 76.6% of the population may be affected by vitamin D (VD) deficiency, which has been linked to increased morbidity and mortality from COVID-19. This underscores the importance of further research into VD supplementation, particularly for health care workers, who are at higher risk due to indoor work environments and dietary challenges associated with shift schedules.

[Comparison of serum uric acid and liver enzyme levels in adolescents with obesity and with metabolic syndrome].

Introduction: a relationship has been observed between elevated levels of liver enzymes and uric acid with the presence of metabolic syndrome (MS) in the pediatric population. Objective: to compare serum liver enzyme and uric acid levels between adolescents with and without MS. Methods: a cross-sectional study was carried out in adolescents with obesity between 10 and 18 years old.

Vitamin D levels in the pre- and post-COVID-19 pandemic periods in pediatric patients with chronic kidney disease.

Introduction: Vitamin D (VD) deficiency is common in children with chronic kidney disease (CKD) because of multiple factors. During the coronavirus disease 2019 (COVID-19) pandemic, it increased because of medicine shortage and no enough medical service for patients with non-COVID-19 diseases.

Objective: To analyze the effects of the COVID-19 pandemic-related lockdown on the serum levels and status of 25-hydroxyvitamin D3 (25-[OH]D) in children with CKD.
