COVID-19 diverse outcomes: Aggravated reinfection, type I interferons and antibodies.

SARS-CoV-2 infection intrigued medicine with diverse outcomes ranging from asymptomatic to severe acute respiratory syndrome (SARS) and death. After more than two years of pandemic, reports of reinfection concern researchers and physicists. Here, we will discuss potential mechanisms that can explain reinfections, including the aggravated ones.

Application of the ARIMA Model to Predict Under-Reporting of New Cases of Hansen's Disease during the COVID-19 Pandemic in a Municipality of the Amazon Region.

This work aimed to apply the ARIMA model to predict the under-reporting of new Hansen's disease cases during the COVID-19 pandemic in Palmas, Tocantins, Brazil. This is an ecological time series study of Hansen's disease indicators in the city of Palmas between 2001 and 2020 using the autoregressive integrated moving averages method. Data from the Notifiable Injuries Information System and population estimates from the Brazilian Institute of Geography and Statistics were collected.

Heme Oxygenase 1 in Vertebrates: Friend and Foe.

HO-1 is the inducible form of the enzyme heme-oxygenase. HO-1 catalyzes heme breakdown, reducing the levels of this important oxidant molecule and generating antioxidant, anti-inflammatory, and anti-apoptotic byproducts. Thus, HO-1 has been described as an important stress response mechanism during both physiologic and pathological processes.

Concordance in prediction body fat percentage of Brazilian women in reproductive age between different methods of evaluation of skinfolds thickness.

Objective: To assess the utility of bioimpedance (BIA) and skinfolds thickness (SF) in body fat percentage measuring (%BF) compared to the reference method dual-energy x-ray absorptiometry (DXA) in Brazilian reproductive age women, as well as to estimate of inter- and intra-observer precision for SF.

Subjects And Methods: 170 women aged 18-37 years with BMI between 18 and 39.9 kg/m2 were selected for this cross-sectional study.

Increased Sympathetic Cardiac Autonomic Modulation after Two Consecutive Tilt Tests in Women with Polycystic Ovary Syndrome.

Objective:  The present study aimed to analyze cardiac autonomic modulation via spectral and symbolic analysis of heart rate variability (HRV) in women with polycystic ovary syndrome (PCOS) who were subjected to two consecutive tilt tests.

Methods:  A total of 64 women were selected and divided into 2 groups: control (without PCOS), and PCOS. Concentrations of follicle-stimulating hormone, luteinizing hormone, prolactin, estradiol, homocysteine, sex hormone-binding globulin, thyroid stimulating hormone, fasting insulin, testosterone, androstenedione, and 17-hydroxyprogesterone levels, triglycerides, free androgen index (FAI), and homeostasis assessment model (HOMA-IR) were assessed.

Leaf and stem micromorphology of Byrsonima sericea DC. by light and scanning electron microscopy.

Micromorphological studies were carried out using multiple microscopic techniques on the leaves and stem bark of Byrsonima sericea DC. (Malpighiaceae), a species popularly known as "murici" and used medicinally, in order to identify both qualitative and quantitative features of leaf and stem anatomy and histochemistry as differential parameters to support both the quality control of its ethnodrugs and the taxonomy of the genus. The study was conducted using traditional techniques of plant anatomy, histochemical tests, and the stomatal index (SI).

Continuous versus intermittent aerobic exercise in the improvement of quality of life for women with polycystic ovary syndrome: A randomized controlled trial.

Polycystic ovary syndrome predisposes alterations which contribute to the reduction of quality of life. This randomized controlled clinical trial study was to evaluate the effect of two protocols of aerobic exercise on quality of life in women with polycystic ovary syndrome. Women were allocated to three groups: continuous aerobic training ( = 28), intermittent aerobic training ( = 29), and control group (no training;  = 30).

Association of measures of central fat accumulation indices with body fat distribution and metabolic, hormonal, and inflammatory parameters in women with polycystic ovary syndrome.

Objective: To investigate the associations among visceral adiposity index (VAI), lipid accumulation product (LAP), body fat percentage (%), and android/gynoid ratio (A/G ratio) in women with polycystic ovary syndrome (PCOS) and verify if the parameters representative of visceral obesity correlate with and exhibit the same frequency as body composition variables; anthropometric indices; and metabolic, hormonal, and inflammatory parameters.

Subjects And Methods: This was a cross-sectional study that included 94 women with PCOS. Hormonal, metabolic, and inflammatory parameters were analyzed in all women.

Comparison of the Effect of Intermittent and Continuous Aerobic Physical Training on Sexual Function of Women With Polycystic Ovary Syndrome: Randomized Controlled Trial.

Background: Polycystic ovary syndrome (PCOS) is a common condition characterized by hyperandrogenism, anthropometric changes (increased weight and waist-to-hip ratio [WHR]), behavioral changes (sexual dysfunction, anxiety, and depression), and reduced quality of life. Physical exercise may reduce many of the adverse effects of PCOS. However, no studies have yet evaluated the effects of aerobic exercise on the sexual function of women with PCOS.

Quality of Life in Women with Polycystic Ovary Syndrome after a Program of Resistance Exercise Training.

Purpose Aerobic exercises may improve quality of life (QoL) in women with polycystic ovary syndrome (PCOS). However, there is no data on the effect of resistance exercise training (RET) programs on the QoL of women with PCOS. Thus, this study aimed to assess the effect of a 16-week RET program on QoL in PCOS women.

Resistance Exercise Impacts Lean Muscle Mass in Women with Polycystic Ovary Syndrome.

Purpose: This study investigated the effects of progressive resistance training (PRT) on lean muscle mass (LMM) in women with or without polycystic ovary syndrome (PCOS) and its effects on metabolic factors and concentrations of related steroid hormones.

Design: This was a nonrandomized, therapeutic, open, single-arm study.

Participants: All in all, 45 sedentary women with PCOS and 52 without (non-PCOS), 18-37 yr of age, with body mass indexes (BMI) of 18-39.

Women with polycystic ovary syndrome have greater muscle strength irrespective of body composition.

The aim of this study was to compare metabolic parameters, body composition (BC) and muscle strength of women with and without polycystic ovary syndrome (PCOS). This was a case-control study that evaluated 40 women with PCOS and 40 controls. Androgens and insulin resistance were measured.
