15. Association between handgrip strength and bone mass parameters in HIV-infected children and adolescents. A cross-sectional study
ABSTRACT BACKGROUND: Low bone mineral content (BMC) and bone mineral density (BMD) have been identified in human immunodeficiency virus (HIV)-infected children and adolescents. The direct adverse effects of HIV infection and combined antiretroviral therapy (ART) negatively contribute to bone metabolism. A direct relationship between muscle strength levels a

16. Reference Equation for the Six-Minute Walk Test in Brazilian Patients with Obesity
Abstract Background: Obesity has repercussions on functional capacity (FC). The six-minute walk test (6MWT) is a useful tool for assessing submaximal FC, and the distance reached at 6 minutes of walking (D6MW) is a relevant prognostic marker. Objective: This paper aims to establish a reference equation for the distance predicted in 6MWT in obese Brazilian

17. Negative affect symptoms, anxiety sensitivity, and vasomotor symptoms during perimenopause
Objective: Vasomotor symptoms affect 60-80% of women during the menopausal transition. Anxiety, depression, and anxiety sensitivity can have an important role in the distressful experience of vasomotor symptoms. Our aim was to evaluate the prevalence and association of vasomotor and negative affect symptoms. Methods: A cross-sectional study was conducted w

18. The impact of COVID-19 on the development and consolidation of telemedicine
ABSTRACT BACKGROUND: Physical activity (PA) is an effective strategy for managing sarcopenia in the elderly, but few studies have addressed PA levels regarding age-related changes. OBJECTIVE: To ascertain the effects of elderly women’s PA levels on sarcopenia, physical performance, handgrip strength and perception of the risk of falling, and their rela
