Introduction: the COVID-19 pandemic incited unprecedented global restrictions on society’s behavior. Home detachment and isolation measures applied during the COVID-19 pandemic can result in problems with sleep quality. It is an important measure to reduce the risk of infection from the COVID-19 outbreak. Objective: to investigate the existence of a difference between the quality of sleep before and during the home distance imposed by the Covid-19 pandemic. Methods: cross-sectional web-based survey was sent using different conventional social media to collect data from the study population. The evaluated group was composed of 124 subjects, 57 of whom were male and 67 were female from the city of Rio Branco / AC. For this study, the Pittsburgh Sleep Quality Index questionnaire (PSQI-BR) and a socio-demographic questionnaire were used. The volunteers received a link along with the description and purpose of the study. Finally, data analysis was performed using SPSS 22.0 software. Results: sleep quality worsened significantly during home distance in four sleep components (subjective sleep quality, sleep latency, sleep drowsiness and overall PSQI score). During social distance, poor sleep was greater among respondents (OR = 5.68; 95% CI = 1.80–17.82; p = 0.70). Conclusion: the results indicated that there was a significant difference between the quality of sleep before and during home detachment and sleep disturbance and the subjective quality of sleep before and during the period of the outbreak of COVID-19 were the components that most worsened in the state of sleep

Objective: the complexity of heart-rate variability (HRV) in amyotrophic lateral sclerosis (ALS) patients with different pulmonary capacities was evaluated. Methods: We set these according to their pulmonary capacity, and specifically forced vital capacity (FVC). We split the groups according to FVC (FVC > 50% (n = 29) and FVC < 50% (n = 28)). In ALS, the presence of an FVC below 50% is indicative of noninvasive ventilation with two pressure levels and with the absence of other respiratory symptoms. As the number of subjects per group was different, we applied the unbalanced one-way analysis of variance (uANOVA1) test after three tests of normality, and effect size by Cohen’s d to assess parameter significance. Results: with regard to chaotic global analysis, CFP4 (p < 0.001; d = 0.91), CFP5 (p = 0.0022; d = 0.85), and CFP6 (p = 0.0009; d = 0.92) were enlarged. All entropies significantly increased. Shannon (p = 0.0005; d = 0.98), Renyi (p = 0.0002; d = 1.02), Tsallis (p = 0.0004; d = 0.99), approximate (p = 0.0005; d = 0.97), and sample (p < 0.0001; d = 1.22). Detrended fluctuation analysis (DFA) (p = 0.0358) and Higuchi fractal dimension (HFD) (p = 0.15) were statistically inconsequential between the two groups. Conclusions: HRV complexity in ALS subjects with different pulmonary capacities increased via chaotic global analysis, especially CFP5 and 3 out of 5 entropies.

Introduction: In studies directed to children and adolescents, the sedentary behavior has been usually represented by exposure to screen, which comprise the total or separate measured time exposed to television, videogame, tablets, mobile devices, and computer. Objective: To analyze the prevalence and factors associated with screen time in children and adolescents. Methods: A cross-sectional school-based study was carried out with 1,471 students from Elementary School, aged between 7 to 18 years (51.3% male), enrolled at public schools (55.6%) in Porto Velho, Rondônia (RO) state, Brazil. Excess screen time was defined as watching television, using the computer, and playing video games for more than two hours per day. Poisson regression was used to obtain crude and adjusted prevalence ratios and their respective 95% CI. Results: Overall prevalence of screen time exposure over two hours per day was 65.9%. After adjustments, risk of screen time exposure was higher in males, PR = 1.51 (95% CI: 1.08 - 1.92), under or equal to 14 years old, PR = 1.69 (95% CI: 1.48 - 1.92), in the 5th grade, PR = 1.41 (95% CI: 1.02 - 1.89), in the 6th grade, PR = 1.44 (95% CI: 1.06 - 1.97) and in the 7th grade, PR = 1.52 (95% CI: 1.09 - 2.13), attending two weekly PE classes or fewer, PR = 1.25 (95% CI: 1.07 - 1.53) ), consuming more than 3 daily meals, PR = 2.69 (95% CI: 2.14 - 3.37) and overweight, PR = 1.51 (95% CI: 1.13 - 2.03). Conclusion: The findings showed that the exposure equal to or more than two hours of daily screen time was high. The students more exposed to this outcome had the next characteristics: male sex, age less than or equal to 14 years, from the fifth, sixth, and seventh grade of elementary education, practice physical education classes less than or equal to two hours per week, consume more than three meals daily and have excess body fat (G%).

Background: Individuals post-stroke commonly presents functional and cardiorespiratory deficits besides a physical inactivity lifestyle in the chronic phase of disease. Considering this, there is a hypothesis that hemodynamic responses could be affected by motor, cognitive and cardiorespiratory deficits during the aerobic exercise. In order to identify functional conditions that can influence the aerobic performance of these individuals, correlations between functional variables and hemodynamic responses during and after the aerobic exercise were studied. As a secondary purpose, the ability of return to hemodynamic resting state were also analyzed. Methods: In this experimental study, after being evaluated about their motor and cognitive function, balance and prognosis, forty participants underwent a 30-minute aerobic exercise session on a treadmill. Training heart rate, arterial blood pressure, oxygen pulse saturation, heart rate, and respiratory rate were measured before begin the exercise session, every five minutes during the exercise and five minutes after it.  Results: Cardiorespiratory parameters within normality limits in all phases of the exercise and the capacity of returning to the resting state were observed. Moderate inverse correlations were found between Berg Scale and oxygen pulse saturation (r=-0.401, p=0.01), between MMSE and diastolic blood pressure (r=-0.406, p=0.009), age and diastolic blood pressure (r=-0.435, p=0.005) and between injury time and RR (r=-0.454, p=0.003). Relationship between the lesion side and the 20 minute phase of aerobic exercise was also observed (p=0.042).   Conclusion: Post- stroke individuals present moderate correlation between hemodynamic and respiratory responses during aerobic exercise and balance, muscle strength, injury time, age and side of lesion. They also have the capacity to return to their cardiorespiratory and cardiovascular resting state right after the activity besides their cardiorespiratory deficits.

The zika virus is an emerging and important world health problem. In public health its harmful effects have stimulated various legal interests. The Federal Government of Brazil recently adopted several social and health surveillance measures, extending the instruments of possibilities to combating the virus transmitter in Brazil. Law No. 13.306/2016 brought incisive determinations about action awareness policies and educational campaigns, and at the same time authorizes the highest authorities of the Unified Health System (SUS) within federal, state, county and municipal governments to establish and implement the necessary measures to control the diseases caused by the virus, i.e. dengue, chikungunya and zika. The published legislation has created a motivating environment for researchers to develop projects aimed at the mosquito that transmits the dengue virus, the chikungunya virus and the zika virus. Therefore, studies on A. aegypti have led to greater scientifi c knowledge about its habitat, reproduction and development and a description of means to combat it, as a precondition for the ful filment of the social purposes of Law No. 13.301, of June 27, 2016, mainly if researches about more efficient management models and management of public finances, contributing to unveiling impacts on public health and growth and human development.

Among the main types of neoplasms in the female population, breast and cervical cancers are the most important due to their high morbidity and mortality rates. The mortality has been proportionally higher in developing countries. Analysis of the trend of cancer mortality in Brazil revealed a considerable difference in the pattern of deaths between the regions.To analyze the trend of mortality due to breast and cervical cancers in women.Retrospective study of a series of death cases, using secondary data from the mortality information system (SIM) of the Ministry of Health. The deaths were identified as the underlying cause of breast and cervical cancers, including malignant neoplasms of the uterus without other specifications, occurring from 1980 to 2014. Thus, the annual standardized age-specific mortality rates by the world population were applied. For trend analysis, regression models were utilized in which the mortality rates were considered dependent variables and years the independent variable. Polynomial regression models and a Prais-Winsten regression model were adopted.Cervical cancer presented a mortality rate ranging from 2.15 to 10.69 per 100,000 women from 1980 to 2014, with a tendency for stability.Breast cancer mortality rate varied from 3.81 to 11.47 per 100,000 women from 1981 to 2014, indicating a growing trend.There is a significant increase in the mortality rate for breast cancer and stability of cervical cancers in the State of Acre from 1980 to 2014, evidencing a concern in their care and monitoring. Above all, guaranteed access, especially to the population of women at social risk, and the search for effective screening should be emphasized in the formation of the care line and the Health Care Network in the State of Acre.
