Exploring the factors influencing the adult population's reluctance to accept the COVID-19 vaccine in Tehran.

Background: While evidence of efficacy, safety, and technical feasibility is crucial when introducing a vaccine, it is equally important to consider the psychological, social, and political factors influencing vaccine acceptance. This study aims to identify the factors contributing to COVID-19 vaccine hesitancy among adults in Tehran, Iran.

Methods: The study employed a descriptive and analytical cross-sectional design carried out from 2021 to 2022.

Fruit and vegetable consumption in diabetics patients: Effect of pender health promotion model (HPM) intervention.

Background: This study was aimed to investigate the effect of the intervention based on Pender's health promotion model (Pender's HPM) to improve the consumption of fruits and vegetables in diabetic patients.

Materials And Methods: The present study was quasi-experiment community-based research conducted on 112 diabetic patients in Sirjan City. Eligible diabetic patients were randomly divided into two experimental and control groups.

Expression of proapoptotic receptors Fas/Fas-L on sperm cells and levels of their soluble forms in seminal fluid from patients with varicocele.

Varicocele is a condition in which the pampiniform venous plexus in the scrotum dilates abnormally during puberty, affecting testicular growth and semen parameters, and is thought to be a major cause of male infertility. The findings of researches on the presence of the Fas system in sperm are controversial. As the main triggers of apoptosis in the semen of patients with varicocele, in this study, we examined the expression of Fas/Fas-L on sperm cells and also the levels of their soluble forms in seminal plasma.

Prediction of Serum Creatinine in Hemodialysis Patients Using a Kernel Approach for Longitudinal Data.

Objectives: Longitudinal data are prevalent in clinical research; due to their correlated nature, special analysis must be used for this type of data. Creatinine is an important marker in predicting end-stage renal disease, and it is recorded longitudinally. This study compared the prediction performance of linear regression (LR), linear mixed-effects model (LMM), least-squares support vector regression (LS-SVR), and mixed-effects least-squares support vector regression (MLS-SVR) methods to predict serum creatinine as a longitudinal outcome.
