Association of scopophobia with online learning fatigue among medical students in Brazil.

Background: Scopophobia can be described in the medical field as the fear of being watched or stared at. Despite the relevance of scopophobia in remote learning scenarios, which have always existed and have been largely expanded during the pandemic in medical education, studies on this topic are exceedingly rare worldwide. Hence, to fill up this gap, a cross-sectional study of medical students was developed to assess the association of scopophobia with the prevalence of online learning fatigue.

Temporal Reduction in COVID-19-Associated Fatality Among Kidney Transplant Recipients: The Brazilian COVID-19 Registry Cohort Study.

Data from the general population suggest that fatality rates declined during the course of the pandemic. This analysis, using data extracted from the Brazilian Kidney Transplant COVID-19 Registry, seeks to determine fatality rates over time since the index case on March 3rd, 2020. Data from hospitalized patients with RT-PCR positive SARS-CoV-2 infection from March to August 2020 (35 sites, 878 patients) were compared using trend tests according to quartiles (Q1: <72 days; Q2: 72-104 days; Q3: 105-140 days; Q4: >140 days after the index case).

Use of neck circumference as a predictor of cardiovascular risk in chronic kidney patients undergoing haemodialysis who are candidates for transplantation.

Introduction: Patients undergoing haemodialysis are at great cardiovascular risk. Neck circumference (NC) is a simple and low-cost measure for estimating this risk precociously. The present study aimed to evaluate whether the cardiovascular risk obtained by NC is associated with the main cardiometabolic risk factors in patients on haemodialysis treatment who are on a waiting list for transplantation.

[Crossed renal ectopia with fusion: report of two cases and review of the literature].

Renal ectopia is one of the most common renal abnormalities of kidney development. However, only a few cases of crossed fused renal ectopia have been reported in the literature. Although crossed renal ectopia is usually clinically silent, they is sometime responsible for infection and urinary stones and may be associated with a high incidence of ureteropelvic junction obstruction, vesicoureteral reflux and renal multicystic dysplasia.

A comparative analysis of pre- and post-dialysis albumin as indicators of nutritional and morbi-mortality risks in haemodialysis patients.

Introduction: Pre-dialysis albumin is likely to be falsely low due to a dilution effect, making its usefulness in assessing protein status questionable. OBJEVTIVES: The purpose of this study was to assess whether post-dialysis albumin would be a better marker of malnutrition and risk of mortality, when compared to pre-dialysis albumin.

Methods: We evaluated the correlation between pre- and post-dialysis albumin and the following parameters: body mass index (BMI), adequacy of muscle arm circumference (MAC) and tricipital skinfold (TS) to the 50th percentile (P50), C-reactive protein (CRP), phase angle (PA), protein equivalent of nitrogen appearance (PNA), the Kt/V index of dialysis adequacy, and the hydration status (Pearson's correlation coefficient).

Purpose: To investigate the correlation of non-HDL-c with anthropometric measurements associated to cardiovascular risk, such as body mass index, waist circumference, waist-to-height ratio, waist-to-height(2) ratio, and waist-to-hip circumference ratio.

Methods: We evaluated anthropometric markers and lipids in 86 hemodialysis patients, and the correlation between them was investigated.
