A study of the professional tensions within nursing organizations in Rio de Janeiro, focusing on the Regional Nursing Council's election period (1990-1993), is undertaken.
A historical retrospective. selleck Our process involved the use of journalistic articles, normative documents, legislation, and semi-structured interviews with five nursing professionals. The interpretation of findings was anchored in Bourdieu's theories of habitus, field, capital, and symbolic power.
The council's electoral code alterations, implemented under the administration's sway from 1987 to 1990, significantly affected re-election candidacy, modifying disclosure and eligibility standards, ultimately discouraging broad participation, especially among members of the Rio de Janeiro branch of the Brazilian Nursing Association.
The studied electoral process in nursing during this era exposed a field of conflicts rooted in power disparities and gender considerations. A particular group's utilization of restrictive strategies made it challenging for the entire profession to engage fully.
In this timeframe, the field of nursing was rife with disagreements concerning power structures and gender differences. These disagreements became apparent in the scrutinized election, which highlighted the exclusionary strategies used by one faction, thereby obstructing participation for the entire nursing profession.

To determine the commonality of allergic rhinitis in adolescents and the connected factors in their parental figures/guardians is the purpose of this study.
A written questionnaire, standardized and validated, was employed in a cross-sectional study. Questionnaires from the Global Asthma Network were completed by adolescents aged thirteen to fourteen years (n=1058) and their parents or guardians (mean age forty-two years; n=896) living in Uruguaiana, Southern Brazil.
A survey of adolescents revealed a prevalence of 280% for allergic rhinitis, 213% for allergic rhinoconjunctivitis, and 78% for severe forms of allergic rhinitis. A remarkable 317 percent of adults demonstrated prevalence of allergic rhinitis. Factors linked to allergic rhinitis in adolescents include infrequent physical activity (OR 216; 95%CI 115-405), the presence of a single older sibling (OR 194; 95%CI 101-372), and a daily intake of meat (OR 743; 95% CI 153-3611). selleck Conversely, the consumption of sugar (OR 0.34; 95% confidence interval 0.12-0.93) or olive oil (OR 0.33; 95% confidence interval 0.13-0.81) was observed. selleck Regular intake of vegetables daily and physical activity once or twice per week were noted as negatively associated factors, with an odds ratio of 0.39 and a 95% confidence interval of 0.15 to 0.99. Home fungal exposure (OR 525; 95% CI 101-2722) and consumption of meat once or twice per week (OR 4645; 95% CI 212-102071) demonstrated a correlation with allergic rhinitis in adults, while a low level of education was conversely linked with a lower risk (OR 0.25; 95% CI 0.007-0.092).
The high prevalence of allergic rhinitis in adolescents parallels the frequency of medical diagnosis for this condition in adults residing in Uruguaiana. Environmental factors, and especially dietary choices, contributed to the observed results across both groups.
Among adolescents, allergic rhinitis is a prevalent condition, and its medical diagnosis in Uruguaiana's adult population is similarly widespread. Findings across both groups revealed a relationship with environmental factors, foremost among them, dietary choices.

This study aimed to compare various equations to find the one that best predicts peak heart rate (HRmax) in children, specifically relating to their body mass.
A meta-analysis (PROSPERO CRD42020190196) was executed on cross-sectional studies with the objective of either validating or developing HRmax equations, with child and adolescent cohorts serving as the study population. The search protocol included Scopus, ScienceDirect, Web of Science, PubMed, and Biblioteca Virtual em Saude, targeting keywords like 'prediction' or 'equation', 'maximal heart rate', 'maximum heart rate', 'determination of heart rate', along with the specific populations 'children' and 'adolescent'. Using the TRIPOD Statement tool, the methodological quality was evaluated, and the subsequent data extraction was performed for analysis. Within the Comprehensive Meta-Analysis platform, the meta-analysis was executed with a significance criterion of p<0.05 and a 95% confidence interval (CI).
Eleven studies were included in the analysis; three generated predictive equations, ten examined the validity of pre-existing models in real-world situations, and one enhanced the values in already developed models. A moderate evaluation of methodological quality was prevalent across the majority of the investigated studies. The equations 164 + (0270 HRres) – (0155 body mass) + (11 METs) + (0258 body fat percent) (r=0500, 95%CI 0426-0567, p<0001) and 1667+ (046 HRres) + (116 maturation) (r=0540, 95%CI 0313-0708, p<0001) showed statistically significant, stronger correlations with measured HRmax in a group of nonobese adolescents. The 208-(07 age) developed predictive model exhibited superior accuracy compared to alternative analytical models (SDM=-0183, 95%CI -0787 to -0422, p=0554). Obese adolescents lacked a specific predictive equation.
Predictive equations for this population require further investigation to help regulate exercise intensity in the therapeutic management of childhood and adolescent obesity.
Subsequent studies should investigate new possibilities for developing predictive equations applicable to this population, facilitating the control of exercise intensity in the therapeutic treatment of childhood and adolescent obesity.

This investigation sought to ascertain vitamin D levels in children and adolescents across various seasons, contrasting levels between those participating in outdoor activities and those engaged in indoor pursuits.
A cross-sectional investigation was undertaken on a sample of 708 children and adolescents (6 to 18 years old). Exclusions were made for 109 participants, including 16 over 19 years, 39 with ongoing medical conditions requiring continuous treatment, 20 participants on continuous medication, and 34 lacking vitamin D data; thereby resulting in a final sample size of 599. To measure the plasma concentration of 25-hydroxyvitamin D2, commercial kits were used, following the manufacturer's instructions meticulously.
Outdoor activity participants and those with spring/summer data exhibited elevated vitamin D levels. A Poisson regression revealed a higher proportion of participants with insufficient vitamin D among those measured in the spring (PR 115, 95%CI 103-129) and winter (PR 118, 95%CI 105-132). Those prioritizing indoor activities demonstrated a higher proportion of insufficient vitamin D intake; the prevalence ratio was 1.08 (95% confidence interval 1.01-1.15).
Participants monitored for vitamin levels during the summer and autumn months had a diminished prevalence of hypovitaminosis D. Despite consistent high solar irradiance throughout the year, substantial seasonal fluctuations in vitamin D levels are observable in certain regions.
Among those participants who assessed their vitamin D status during the summer and autumn months, the proportion with hypovitaminosis D was lower. Year-round high solar radiation does not guarantee consistent vitamin D levels, which can vary greatly depending on the time of year.

To determine the methodological characteristics affecting anthropometric measurements, this study examined research on the nutritional state of individuals with cystic fibrosis (CF).
PubMed, Embase, and Web of Science databases were searched in MEDLINE to identify pertinent publications. Cystic fibrosis was the defining characteristic of the population, composed of children and adolescents. Inclusion criteria encompassed observational studies and clinical trials that employed anthropometric and body composition measurements, utilizing dual-energy X-ray absorptiometry (DXA) and bioelectrical impedance assessment (BIA). Defining a standardized data collection process required details about the instruments and their calibration, the measurement procedures employed, and confirmation of measurement by a trained team, or the citation of an anthropometric reference manual. Frequencies, both absolute and relative, were used to represent the extracted data.
The dataset incorporated a total of 32 articles, and a total of 233 metrics or indices were noted. Weight (kg), body mass index (kg/m^2), and height (cm) were among the frequently utilized measures in the study. Body mass index (kg/m^2) was used 35% of the time, whereas weight and height each comprised 33% of the overall measurements. Of the 28 studies utilizing anthropometric measurements, 21 (75%) furnished a comprehensive or partial account of the employed measuring instruments, while 3 (11%) detailed equipment calibration procedures, 10 (36%) elucidated the measurement protocols implemented by the assessors, and 2 (7%) specified that the measurements were performed by a trained team.
The inadequate methodology for measurement procedures hindered a meaningful assessment of data quality.
