In this longitudinal study, we evaluated the sensitivities of dual-echo, conventional spin-echo (CSE), and rapid-acquisition relaxation-enhanced (RARE) scans for detecting the appearance of new lesions in multiple sclerosis (MS). Dual echo, CSE, and RARE scans were obtained on four occasions each separated by 28 days from five patients with relapsing-remitting MS using a 1.5-Tesla machine. A total of 44 new lesions were detected by the two sequences. Thirty-five lesions were seen on both sequences, three only on CSE and six only on FSE. This study indicates that CSE may be substituted by RARE when monitoring short-term disease activity in MS.

The scope of this study was to determine the diagnostic performance of ABSI for obesity and sarcopenic obesity, compared to the results of bioimpedance analysis (BIA) and BMI, by sex and age group. It involved a cross-sectional study with 12,793 participants in the second round of ELSA-Brasil (Longitudinal Study of Adult Health in Brazil), which obtained measurements of body fat percentage using BIA and anthropometry, verifying the performance of the diagnostic tests in order to compare the indices. The results showed that for obesity in men in all three age groups, the sensitivity was below 49%.

This study aims to examine the prevalence of abdominal obesity-dynapenia phenotype, identified by the presence of abdominal obesity and dynapenia, and understand its associated factors with a representative sample of the Brazilian population. Data were collected from the baseline of the Brazilian Longitudinal Study of Aging (ELSI-Brasil) 2015-2016. Abdominal obesity was determined by a waist-to-height ratio ≥ 0.

Purpose: Adolescent girls are at high risk for depression and human immunodeficiency virus (HIV) acquisition. Poor mental health can increase vulnerability to risky sexual behaviours. Therefore, this study aims to determine the prevalence of depressive symptomology and explore the convergence of HIV risk factors with depressive symptoms amongst cis-gender adolescent girls and young women (AGYW) in rural KwaZulu-Natal (KZN) and peri-urban Western Cape (WC) communities in South Africa.
