In Ro Grande do Sul, the results show a negative impact of the COVID-19 pandemic on the provision of primary teeth dental procedures.

During the period of the Regional Nursing Council elections in Rio de Janeiro (1990-1993), a deeper look at the professional challenges confronting nursing organizations will be conducted.
A historical retrospective. Technology assessment Biomedical Our process involved the use of journalistic articles, normative documents, legislation, and semi-structured interviews with five nursing professionals. Interpreting the findings relied on Bourdieu's conceptual tools of habitus, field, capital, and symbolic power.
The influence of the administration, during the 1987-1990 period, upon the aforementioned council's electoral code, resulted in changes that modified candidate disclosure and eligibility, hindering broad participation, and particularly impacting the Rio de Janeiro branch of the Brazilian Nursing Association.
Nursing, in this timeframe, generated a field of disputes related to gender and power dynamics, particularly observed in the analyzed election process. The use of exclusionary strategies by a select group made participation difficult for the entire category.
The nursing profession, during this particular period, faced considerable debate regarding power dynamics and gender roles. This was underscored in the studied election process, where the use of restrictive strategies by a group significantly hampered participation from the entire profession.

The study sought to evaluate the incidence of allergic rhinitis in adolescents and the associated elements within their families.
A cross-sectional study utilized a standardized and validated written questionnaire for data collection. Thirteen to fourteen year old adolescents (n=1058) in Uruguaiana, southern Brazil, and their parents/guardians (mean age 421 years; n=896) completed the Global Asthma Network standardized questionnaires.
A survey of adolescents revealed a prevalence of 280% for allergic rhinitis, 213% for allergic rhinoconjunctivitis, and 78% for severe forms of allergic rhinitis. Among adults, the prevalence of allergic rhinitis reached 317 percent. Among adolescents, allergic rhinitis is associated with a limited amount of physical activity (OR 216; 95% CI 115-405), having only one older sibling (OR 194; 95% CI 101-372), and daily consumption of meat (OR 743; 95% CI 153-3611). bone and joint infections 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. RXC004 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. Exposure to household fungi (OR 525; 95% CI 101-2722) and meat consumption 1-2 times a week (OR 4645; 95% CI 212-102071) were found to be associated with allergic rhinitis in adults. In contrast, lower educational levels were inversely associated with this condition (OR 0.25; 95% CI 0.007-0.092).
The incidence of allergic rhinitis is substantial among adolescents, just as it is frequently diagnosed in adults within Uruguaiana. The observed results in both groups were linked to environmental factors, chief among them dietary habits.
Allergic rhinitis is quite common among adolescents, and its medical identification is likewise significant in adults in Uruguaiana. Food habits, a prominent environmental factor, were linked to the findings observed in both groups.

The objective of this study was to identify the equation which best predicted maximum heart rate (HRmax) within the pediatric population, contingent on varying body masses.
In a meta-analysis (PROSPERO CRD42020190196), we reviewed cross-sectional studies aimed at validating or constructing HRmax equations using children and adolescents as the subject group. A search was performed in Scopus, ScienceDirect, Web of Science, PubMed, and Biblioteca Virtual em Saude, including search terms such as 'prediction' or 'equation', 'maximal heart rate', 'maximum heart rate', 'determination of heart rate', 'children', and 'adolescent'. To evaluate the methodological quality, the TRIPOD Statement tool was employed, and the pertinent data were subsequently extracted for analysis. The Comprehensive Meta-Analysis program was used for the meta-analysis, which was conducted with a p-value less than 0.05 and a 95% confidence interval (CI).
Eleven studies were reviewed; of these, three formulated predictive equations, ten validated existing models' external applicability, and one enhanced pre-existing equation parameters. The results of the methodological quality assessment showed a generally moderate grading in the majority of the studies. Stronger correlations were observed between measured HRmax in nonobese adolescents and the equations 164 + (0270 HRres) – (0155 body mass) + (11 METs) + (0258 body fat percent) (r=0500, 95%CI 0426-0567, p<0001), exhibiting a significant association. Furthermore, the equation 1667+ (046 HRres) + (116 maturation) (r=0540, 95%CI 0313-0708, p<0001) also displayed a stronger correlation with measured HRmax in this group. 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.
Further research is warranted to explore innovative predictive equations for this population, ultimately aiming to control exercise intensity during therapeutic management of childhood and adolescent obesity.
Further research should focus on creating new predictive equations that will be a valuable tool for controlling exercise intensity in the therapeutic management of obesity in children and adolescents.

To confirm vitamin D concentration in children and adolescents during distinct seasons, and to differentiate these concentrations between children actively participating in outdoor activities and those engaged in indoor activities, this research was conducted.
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. The measurement of the plasma concentration of 25-hydroxyvitamin D2 was performed using commercial kits, the procedure being guided by the manufacturer's instructions.
A correlation was observed between outdoor activity engagement and elevated vitamin D levels, particularly among participants with spring or summer data. According to Poisson regression, the proportion of participants with inadequate levels of vitamin D was greater in those measured during the spring (PR 115, 95%CI 103-129) and winter (PR 118, 95%CI 105-132). A significantly greater incidence of vitamin D inadequacy was noted among those predominantly engaged in indoor pursuits (PR 1.08, 95% CI 1.01-1.15).
Participants monitored for vitamin levels during the summer and autumn months had a diminished prevalence of hypovitaminosis D. Even in locations enjoying abundant sunlight annually, vitamin D concentrations experience considerable seasonal variation.
Individuals measuring vitamin D levels throughout the summer and fall seasons experienced a decreased incidence of hypovitaminosis D. Seasonal fluctuations in vitamin D levels are pronounced, even in regions that receive abundant solar radiation year-round.

The research project explored the methodological aspects pertinent to anthropometric measurements in studies assessing the nutritional well-being of individuals diagnosed with cystic fibrosis (CF).
Publications were culled from MEDLINE databases (PubMed, Embase, and Web of Science) to inform the search. The population was composed of children and adolescents suffering from cystic fibrosis. Clinical trials and observational studies encompassing anthropometric and body composition parameters, as measured by dual-energy X-ray absorptiometry (DXA) and bioelectrical impedance analysis (BIA), were deemed suitable for inclusion. The criteria for a standardized data collection process included a description of instruments and their calibration, a detailed explanation of the measurement procedures, and verification of measurements by a trained team, or reference to an anthropometric manual. The extracted data were displayed using both absolute and relative frequencies.
Thirty-two articles were encompassed in the study, and 233 metrics or indexes were found. Body mass index (kg/m2), accounting for 35% of the frequency, was a commonly used measurement, alongside weight (kg), which constituted 33% of the measurements, and height (cm) at 33%. In a group of 28 studies employing anthropometric measurements, 21 (75%) provided a complete or partial description of the measuring instruments, 3 (11%) reported on the calibration of equipment, 10 (36%) indicated the measurement procedures used by assessors, and 2 (7%) declared that trained personnel carried out the measurements.
The problematic explanation of measurement methods made it impossible to evaluate the quality of the data effectively.
