Lack of knowledge about the human papillomavirus vaccine among Brazilian adolescents: A cross-sectional study.

To analyze the distribution and factors associated with lack of knowledge about the human papillomavirus (HPV) vaccine among Brazilian adolescents.Cross-sectional study using the 2019 National School Health Survey among 17,805 Brazilian students of public and private schools, aged 13-17 years. The outcome variable was "lack of knowledge about the HPV vaccine" and the explanatory variables were sociodemographic, behaviors, knowledge, and health conditions. Logistic regression model was used to calculate Odds Ratio (OR) and 95% confidence intervals (95%CI). Spatial analysis techniques were used to determine the formation of clusters in the federated units with similar proportions of adolescents who were unaware of the vaccine. The lack of knowledge about the HPV vaccine was reported by 45.54% of Brazilian students. There was a higher chance of lack of knowledge having had sexual intercourse (OR 1.43; 95% CI 1.20-1.70); attending public school (OR 1.72; 95%CI 1.47-2.02) and located in the Northeast Region (OR 1.35; 95%CI 1.08-1.69). The lower chance of lack of knowledge were female gender (OR 0.41; 95% CI 0.35-0.48), higher maternal education (OR 0.62; 95% CI 0.50-0.77) self-rated health as Poor/very poor (OR 0.64; 95% CI 0.49-0.86) and receiving contraceptive counseling (OR 0.77; 95% CI 0.65-0.91). The proportion of lack of knowledge about the HPV vaccine was higher with the formation of High-High spatial clusters in the states of Maranhão, Piauí, and Pernambuco. Sociodemographic, health, and behavioral conditions and knowledge of students, as well as school characteristics, were associated with lack of knowledge about the HPV vaccine. A higher frequency of lack of knowledge about the HPV vaccine among adolescents was found in the states of the Northeastern Region.

Expression of HOXA10 and HOXA11 in the endometrium of infertile patients with chronic endometritis.

OBJECTIVE: The study aimed to evaluate the impact of CE on the expression of HOXA10 and HOXA11 during the late proliferative phase in the endometrium of infertile women. METHODS: A prospective, translational cohort study was conducted in partnership with the Hospital Universitário Antônio Pedro in Niterói and the Clínica Ginendo in Rio de Janeiro after approval by the Ethics Committee. The patients were selected to participate in the study after showing an indication for hysteroscopy. All participants were divided into three groups: infertile women with endometritis (n=10), infertile women without endometritis (n=17) and fertile women without endometritis (n=10). At hysteroscopy, two endometrial samples were obtaneid, with one sent for histopathological examination per the gynecologist's request and the other used for immunohistochemistry procedures to evaluate the expression of CD138, HOXA10 and HOXA11. CD138 was used to confirm the diagnosis of CE. The analysis of HOXA10 and HOXA11 was performed using the HScoring method for immunohistochemistry with polyclonal antibodies. RESULTS: Women with and without endometritis had lower HOXA10 and HOXA11 expression values than women in the control group (fertile women without endometritis). CONCLUSIONS: The expression of HOXA10 and HOXA11 during the proliferative phase is not significantly different between infertile women with endometritis and infertile women without endometritis. Translational studies with a larger number of patients should be performed.

Involvement of GPR43 Receptor in Effect of Lacticaseibacillus rhamnosus on Murine Steroid Resistant Chronic Obstructive Pulmonary Disease: Relevance to Pro-Inflammatory Mediators and Oxidative Stress in Human Macrophages.

BACKGROUND: Cytokine storm and oxidative stress are present in chronic obstructive pulmonary disease (COPD). Individuals with COPD present high levels of NF-κB-associated cytokines and pro-oxidant agents as well as low levels of Nrf2-associated antioxidants. This condition creates a steroid-resistant inflammatory microenvironment. Lacticaseibacillus rhamnosus (Lr) is a known anti-cytokine in lung diseases; however, the effect of Lr on lung inflammation and oxidative stress in steroid-resistant COPD mice remains unknown. OBJECTIVE: Thus, we investigated the Lr effect on lung inflammation and oxidative stress in mice and macrophages exposed to cigarette smoke extract (CSE) and unresponsive to steroids. METHODS: Mice and macrophages received dexamethasone or GLPG-094 (a GPR43 inhibitor), and only the macrophages received butyrate (but), all treatments being given before CSE. Lung inflammation was evaluated from the leukocyte population, airway remodeling, cytokines, and NF-κB. Oxidative stress disturbance was measured from ROS, 8-isoprostane, NADPH oxidase, TBARS, SOD, catalase, HO-1, and Nrf2. RESULTS: Lr attenuated cellularity, mucus, collagen, cytokines, ROS, 8-isoprostane, NADPH oxidase, and TBARS. Otherwise, SOD, catalase, HO-1, and Nrf2 were upregulated in Lr-treated COPD mice. Anti-cytokine and antioxidant effects of butyrate also occurred in CSE-exposed macrophages. GLPG-094 rendered Lr and butyrate less effective. CONCLUSIONS: Lr attenuates lung inflammation and oxidative stress in COPD mice, suggesting the presence of a GPR43 receptor-dependent mechanism also found in macrophages.

Multiple behavioral risk factors for non-communicable diseases among the adolescent population in Brazil: the analysis derived from the Brazilian national survey of school health 2019.

BACKGROUND: Health risk behaviors often emerge or intensify during adolescence and tend to co-occur, exposing individuals to an even greater risk for the development of non-communicable diseases (NCDs). The likelihood of exhibiting multiple health risk factors also increases throughout life and is associated with sociodemographic characteristics contributing to their escalation and severity. In this context, the objective of this study was to analyze the association between sociodemographic characteristics and multiple behavioral risk factors for non-communicable diseases among the adolescent population in Brazil. METHODS: This cross-sectional study utilized data from the Brazilian National Survey of School Health 2019. The sample comprised 121,580 adolescents aged 13 to 17. The analyzed variables included irregular intake of fruits and vegetables, regular consumption of soft drinks and treats, insufficient physical activity, sedentary lifestyle, cigarette smoking, and alcohol consumption. To analyze MBRFs, a classification ranging from zero to five was created, and associations were estimated using Odds Ratio (OR) with the respective 95% confidence interval (CI). The Backward method was employed for the multivariate regression model, utilizing ordinal logistic regression. RESULTS: Adolescents without behavioral risk factors for NCDs constituted only 3.9% (95% CI 3.7-4.1). The most prevalent categories were two and three MBRFs, accounting for 28.3% (95% CI: 27.7-28.8) and 27.0% (95% CI: 26.5-27.5), respectively. Adolescents aged 16 and 17 (ORadj: 1.39; 95% CI: 1.32-1.48), residing in the Brazilian Southeast (ORadj: 1.66; 95% CI: 1.52-1.81), and those reporting poor or very poor self-rated health (ORadj: 2.05; 95% CI: 1.87-2.25) were more likely to exhibit multiple behavioral risk factors. Conversely, male adolescents (adjusted OR: 0.65; 95% CI: 0.62-0.69), those of mixed race (adjusted OR: 0.92; 95% CI: 0.87-0.97), and residents of rural areas (adjusted OR: 0.76; 95% CI: 0.70-0.84) were less likely to manifest MBRFs for NCDs. CONCLUSION: The majority of adolescents displayed MBRFs for NCDs, positively associated with age, region, and perceived health status. This underscores the necessity for healthcare promotional interventions throughout the life cycle, as these behaviors may persist into adulthood.

Prevalence and factors associated with possible cases of familial hypercholesterolemia in Brazilian adults: a cross-sectional study.

This study aimed to estimate the prevalence of possible cases of FH and analyze associated factors in the adult Brazilian population. Cross-sectional study with laboratory data from the Brazilian National Health Survey, with 8521 participants. Possible cases of FH were defined according to the Dutch Lipid Clinic Network criteria. The prevalence and 95% confidence intervals (95% CI) of possible cases of FH were estimated according to sociodemographic variables, lifestyle, diabetes, hypertension, altered tests, treatment and self-rated health. Logistic regression was used to analyze the associations. The prevalence of possible cases of FH was 0.96%, higher in women, between 45 and 59 years, white race/skin color and others, less education, people with diabetes, hypertension and total cholesterol ≥ 310 mg/dL. The presence of FH was positively associated with regular self-rated health (OR 1.96; 95% CI 0.99-3.84), poor/very poor (OR 3.02; 95% CI 1.30-7.03) and negatively with black race/skin color (OR 0.10; 95% CI 0.02-0.46) and complete elementary school, incomplete high school (OR 0.47; 95% CI 0.23-0.98) and complete high school and more (OR 0.45; 95% CI 0.21-0.95). FH affects 1:104 Brazilian adults, these findings contribute to understanding the burden of disease in Brazil. Due to the scarcity of studies on FH in low- and middle-income countries, further studies are desirable.

Temporal and spatial distribution trends of polio vaccine coverage in less than one-year old children in Brazil, 2011-2021.

BACKGROUND: Low polio vaccine coverage can result in the spread of Poliovirus to areas free from viral circulation. This study analyzed the temporal trends and spatial distribution of polio vaccine coverage in one year-old children in Brazil, between 2011 and 2021. METHODS: This was an ecological, time-series study (2011 to 2021) with annual vaccine coverages against poliomyelitis, extracted from the Information System of the National Immunization Program from the 26 States and the Distrito Federal (DF). The percentage reductions in vaccination coverage in Brazil and in the Regions were calculated. Prais-Winsten regression models were used to analyze time series for the Regions and States, and spatial analysis identified the distribution of clusters (high-high; low-low; high-low and low-high) of vaccination coverages across Brazilian municipalities, using a 5% significance level. RESULTS: From 2011 to 2021, the coverage of polio vaccines decreased by 29,9%. There was a progressive increase observed in clusters resulting in low vaccination coverages (140 low-low Brazilian municipalities in 2011 vs. 403 in 2021), mostly reported in the North and Northeast regions of the country. There was a downward trend in vaccination coverages in 24 of the 26 States and DF (p ≤ 0.05). CONCLUSIONS: The reduction in polio vaccine coverage, as observed in the North and Northeast regions of Brazil, may favor the spread of Poliovirus. Therefore, vaccination strategies should be prioritized for children residing in areas with sharp and recurrent declines in vaccination coverages, including travelers, migrants, and refugees.

Anaerobic adhesives effect on counter-torque of abutment screws on implants with external hexagon and conical connections: An in vitro study.

BACKGROUND: Abutment screw loosening is a common complication of implant supported prostheses, especially for single crowns. In engineering, anaerobic adhesives (AA) are used to provide chemical locking between screw surfaces, but their application in implantology remains unclear. PURPOSE: The purpose of this article is to evaluate, in vitro, the effect of AA on counter-torque of abutment screws for cemented prosthesis on dental implants with external hexagon connection (EHC) and conical connection (CC). MATERIALS AND METHODS: Sample was composed by 60 specimens, 30 dental implants with EHC and 30 with CC. Abutments (transmucosal 3 mm straight universal abutment) were installed without AA (control group) or with application of AA with two different adhesive strength: medium strength (LOCTITE® 242) and high strength (LOCTITE® 277). The specimens were subjected to mechanical cycling at 37°C, with a load setting of 133 N, a 1.3 Hz frequency, and 1 200 000 cycles. The abutments were removed, and the counter-torque values were registered. Screws and implants were inspected using a stereomicroscope to verify the presence of residual adhesive and damage the internal structures. The data were analyzed using descriptive statistics and comparison tests (p < 0.05). RESULTS: Comparing to the torque of installation, the medium strength AA kept the counter-torque values for CC implants and the high strength AA kept the counter-torque for EHC implants and increased for CC implants. In the intergroup comparisons, control group presented significantly lower counter-torque values than other groups, both for EHC and CC implants. High strength AA presented similar results to medium strength AA in the EHC implants, but in the CC implants presented higher counter-torque values. Damage in threads was more frequent in the groups that received high strength AA. CONCLUSION: The use of AA increased the counter-torque of abutment screws, both in implants with EHC and CC.

Environmental heterogeneity of a tropical river-to-sea continuum and its relationship with structure and phytoplankton dynamics - Lençóis Maranhenses National Park.

ß-diversity and functional traits of phytoplankton indicators associated with environmental heterogeneity were investigated as environmental quality descriptors in coastal (CS), estuarine (ES), and limnetic (LS) sectors in a tropical river-to-sea ecosystem. Results showed that environmental heterogeneity was marked by spatial differences, contributing to biological heterogeneity. Sporadic and recurrent blooms were associated with environmental spatiotemporal variations and reflected a reduction in ES α-diversity. Salinity acted as an environmental filter that governed the structure and dynamics of the community. The spatial heterogeneity and high turnover of phytoplankton resulted in reliable bioindicators selection. Colonial, bloom-forming and harmful species were associated with highly suspended particulate matter (SPM) because these species are better adapted to these conditions. Species small in size were associated with high concentrations of silicate and chlorophyll-a in the ES because of the occurrence of diatom recurrent blooms. Most flagellates indicators genera have bloom-forming potential. Integrating morphofunctional with taxonomic approaches enabled detailed observations of environmental filters, supporting the selection of priority species and areas for introducing biodiversity monitoring programs and conservation in tropical ecosystems.

Efeito da curcumina e três análogos ­ DMAD, DMAM E RI75 ­ sobre viabilidade, diferenciação e expressão gênica em pré-osteoblastos / Effect of curcumin and three of its analogues - DMAD, DMAM and RI75 - on pre-osteoblast cells' viability, differentiation, and gene expression

A curcumina, encontrada nos rizomas da cúrcuma (Curcuma longa L.), tem sido amplamente estudada devido aos seus potenciais benefícios à saúde que, entre outros, incluem propriedades anti-inflamatórias, antioxidantes e cicatrizantes. No entanto, devido à sua baixa biodisponibilidade e farmacocinética desfavorável, compostos análogos são desenvolvidos e estudados para obter melhores características biofarmacêuticas e aumentar os efeitos biológicos. Neste trabalho, avaliamos a atividade da curcumina e três de seus análogos sintéticos (DMAD, DMAM e RI75) sobre a viabilidade e diferenciação de uma linhagem celular pré-osteoblástica (MC3T3-E1). A expressão dos genes fator de crescimento endotelial vascular (vegf), do ligante 12 da quimiocina de motivo C-X-C (cxcl12) e do fator de transcrição runt- related 2 (runx2) também foi avaliada. As células foram estimuladas com curcumina e os três análogos usando concentrações de 10, 30 ou 50 µM. A curcumina e os análogos testados apresentaram nenhuma, ligeira ou moderada citotoxicidade celular em comparação com o controle negativo, após 24, 48 e 72 horas, nas concentrações testadas. Os resultados de atividade de mineralização para a curcumina e o análogo DMAD não apresentaram diferença estatística com o grupo controle, enquanto os análogos DMAM e RI75 apresentaram menor atividade de mineralização. Nenhuma das substâncias apresentou expressão gênica diferencial de cxcl12, um ativador de células endoteliais e inflamatórias. Por outro lado, em comparação com o controle, o análogo de curcumina RI75 mostrou regulação positiva de runx2 e vegf, ambos relacionados ao reparo tecidual. Os resultados sugerem que os análogos DMAD, DMAM e RI75 apresentam citotoxicidade semelhante ou inferior à curcumina natural e maior atividade biológica, com destaque para o análogo RI75, sendo substâncias com potencial promissor para biomodificações de materiais.

Curcumin, found in the rhizomes of turmeric (Curcuma longa L.), has been widely studied due to its potential health benefits which, among others, include anti inflammatory, antioxidant and healing properties. However, due to their low bioavailability and unfavorable pharmacokinetics, analogous compounds are developed and studied to obtain better biopharmaceutical characteristics and increase biological effects. In this work, we evaluated the activity of curcumin and three of its synthetic analogues (DMAD, DMAM and RI75) on the viability and differentiation of a pre-osteoblastic cell line (MC3T3-E1). The expression of the genes vascular endothelial growth factor (vegf), C-X-C motif chemokine ligand 12 (cxcl12) and runt related transcription factor 2 (runx2) was also evaluated. Cells were stimulated with curcumin and the three analogues using concentrations of 10, 30 or 50 µM. Curcumin and the analogues tested showed no, slight or moderate cellular cytotoxicity compared to the negative control, after 24, 48 and 72 hours, at the concentrations tested. The mineralization activity results for curcumin and the DMAD analogue showed no statistical difference with the control group, while the DMAM and RI75 analogues showed lower mineralization activity. None of the substances showed differential gene expression of cxcl12, an activator of endothelial and inflammatory cells. On the other hand, compared to the control, the curcumin analogue RI75 showed upregulation of runx2 and vegf, both related to tissue repair. The results suggest that the DMAD, DMAM and RI75 analogues present similar or lower cytotoxicity compared to natural curcumin and greater biological activity, especially the RI75 analogue, being, therefore, substances with promising potential for biomodification of materials.

ABSTRACT Objective: To estimate the reference intervals (RIs) of complete blood count parameters in the Brazilian adult population. Methods: Cross-sectional study, with data from the National Health Survey (Pesquisa Nacional de Saúde - PNS), between 2014-2015. The final sample consisted of 2,803 adults. To establish the RIs, exclusion criteria were applied, outliers were removed and partitions were made by gender, age, and race/skin color. The non-parametric method was adopted. Differences were assessed using the Mann Whitney and Kruskal Wallis tests (p≤0.05). Results: There were statistically significant differences for the following hematological parameters based on gender, red blood cells, hemoglobin, hematocrit, MCH, MCHC, eosinophils and absolute monocytes, neutrophils and platelets (p≤0.05). When analyzed by age, the RIs were statistically different in females for hematocrit, MCV, white blood cells and RDW and in males for red blood cells, white blood cells, eosinophils, mean platelet volume, MCV, RDW, and MCH (p≤0.05). For race/color, there were differences in the RIs for parameters of hemoglobin, MCH, MCHC, white blood cells and mean platelet volume, neutrophils and absolute eosinophils (p≤0.05). Conclusion: The differences found in the RIs of some in blood count parameters in Brazilian adults reaffirm the importance of having their own laboratory reference standards. The results can support a more accurate interpretation of tests, adequate identification and disease prevention in Brazil.

Amamentação na primeira hora de vida na maternidade: fatores intervenientes / Factors intervening in breastfeeding in the first hour of life on the maternity ward / Factores interventores en la lactancia materna en la primera hora de vida en la maternidad

Objetivo: descrever os fatores intervenientes na amamentação na primeira hora de vida na maternidade na perspectiva de puérperas e profissionais de enfermagem. Método: estudo qualitativo, desenvolvido no segundo semestre de 2019, em um hospital do interior do Rio de Janeiro, mediante entrevistas semiestruturadas. Utilizaram-se o software Interface de R pour les Analyses Multidimensionnelles de Textes et de Questionnaires (IRAMUTEQ®) e a Análise Temática. Protocolo de pesquisa aprovado pelo Comitê de Ética em Pesquisa. Resultados: percebeu-se que nem todos os recém-nascidos são amamentados na primeira hora por fatores ligados à mãe, condições clínicas do bebê, tipo de parto, profissionais ou instituição. O teste rápido anti-HIV se mostrou um fator limitador, pois seu resultado é liberado somente após o parto. Ademais, as orientações pela equipe de enfermagem favorecem essa prática, enquanto a falta de rotina a prejudica. Conclusão: fatores multidimensionais interferem na amamentação na primeira hora de vida na maternidade.

Objective: to describe the factors intervening in breastfeeding in the first hour of life in the maternity ward from the perspective of mothers and nursing personnel. Method: this qualitative study was conducted semi-structured interviews, in the second half of 2019, in a hospital in the interior of Rio de Janeiro State. The Interface de R pour les Analyzes Multidimensionnelles de Textes et de Questionnaires (IRAMUTEQ®) and Thematic Analysis were used. The research protocol approved by the research ethics committee. Results: it was found that not all newborns are breastfed in the first hour due to factors relating to the mother, the baby's clinical condition, delivery type, health personnel, and institution. The rapid anti-HIV test proved to be a limiting factor, as the result is released only after delivery. Furthermore, the guidelines provided by the nursing team favor this practice, while the lack of that routine harms it. Conclusion: multidimensional factors interfere with breastfeeding in the first hour of life on the maternity ward.

Objetivo: describir los factores que intervienen en la lactancia materna en la primera hora de vida en la sala de maternidad en la perspectiva de las madres y profesionales de enfermería. Método: estudio cualitativo, desarrollado durante el segundo semestre de 2019, en un hospital del interior de Río de Janeiro, a través de entrevistas semiestructuradas. Se utilizaron los softwares Interface de R pour les Analyses Multidimensionnelles de Textes et de Questionnaires (IRAMUTEQ®) y el Análisis Temático. El Comité de Ética en Investigación aprobó el protocolo de investigación. Resultados: se percibió que no todos los neonatos son amamantados en la primera hora debido a factores relacionados con la madre, condiciones clínicas del bebé, tipo de parto, profesionales o institución. La prueba rápida anti-VIH resultó ser un factor limitante, ya que su resultado se da a conocer sólo después del parto. Además, las orientaciones proporcionadas por el equipo de enfermería favorecen esa práctica, mientras que la falta de rutina la perjudica. Conclusión: factores multidimensionales interfieren en la lactancia materna en la primera hora de vida en la sala de maternidad.

Vaccination against human papillomavirus in Brazilian schoolchildren: National Survey of School Health, 2019.

OBJECTIVE: to analyze the prevalence of schoolchildren vaccinated against human papillomavirus (HPV) and the reasons related to non-vaccination. METHOD: cross-sectional study, with data from the 2019 National Survey of School Health. The sample consisted of 160,721 students aged 13 to 17 years. The prevalence and confidence intervals (95%CI) of vaccinated adolescents were estimated according to location, sex, and administrative dependence of the school. The differences between the strata were evaluated with the Chi-square test. Adjusted prevalence ratios (aPR) and 95%CI were estimated with the Poisson regression model. RESULTS: most of the students were vaccinated (62.9%), and the prevalence of girls (76.1%) was higher than that of boys (49.1%). The most prevalent reason for not vaccinating was "did not know they had to take" (46.8%), with the highest aPR in public schoolchildren in Brazil (1.6; 95%CI 1.5;1.7), from the Northeast region (1.2; 95%CI 1.1;1.2), and in students from private schools in the Northeast regions (1.1; 95%CI 1.1;1.2) and North (1.3; 95%CI 1.2;1.4). CONCLUSION: one out of every two Brazilian schoolchildren was vaccinated against HPV. Misinformation was a recurring reason for non-vaccination. The North and Northeast regions had the highest prevalence of non-vaccinated people, observed mainly in adolescents from public schools. HIGHLIGHTS: (1) 63% of Brazilian schoolchildren reported having been vaccinated against human papillomavirus (HPV).(2) In Brazil, in 2019, the prevalence of immunized girls was higher than that of boys.(3) Misinformation and fear are reasons for hesitating vaccination.(4) Social and health inequalities may reflect upon HPV vaccination.(5) Achieving the goal of 80% in HPV vaccination coverage is a challenge in Brazil.

Prevalence and factors associated with self-reported diagnosis of high cholesterol in the Brazilian adult population: National Health Survey 2019. / Prevalência e fatores associados ao diagnóstico autorreferido de colesterol alto na população adulta brasileira: Pesquisa Nacional de Saúde 2019.

OBJECTIVE: To estimate the prevalence of self-reported high cholesterol diagnosis and to analyze the factors associated with the prevalence in the Brazilian adult population. METHODS: Cross-sectional study, using data from the 2019 National Health Survey. The diagnosis of high cholesterol was self-reported. Poisson regression models yielded prevalence ratios (PR) and 95% confidence intervals (95%CI). RESULTS: In the 88,531 adults, the prevalence of high cholesterol was 14.6%. Positively associated: female sex (PR = 1.44; 95%CI 1.40;1.52), age ≥ 60 years (PR = 3.80; 95%CI 3.06;4.71), health insurance (PR = 1.33; 95%CI 1.24;1.42), poor or very poor self-rated health (PR = 1.75; 95%CI 1.60;1.90), hypertension (PR = 1.78; 95%CI 1.68;-1.89), diabetes (RP = 1.54; 95%CI 1.45;1.65), renal failure (PR = 1.33; 95%CI 1.15;1.53), obesity (PR = 1.27; 95%CI 1.18;1.36), former smoker (PR = 1.13; 95%CI 1.07;1.20), alcohol abuse (PR = 1.11; 95%CI 1.01;1.21), physically active during leisure time (PR = 1.22; 95%CI 1.15;1.30). CONCLUSION: High cholesterol was associated with sociodemographic characteristics, health condition and lifestyle.

Yellow fever vaccination before and during the covid-19 pandemic in Brazil.

OBJECTIVE: To analyze the number of yellow fever vaccine doses administered before and during the covid-19 pandemic in Brazil. METHODS: This is an ecological, time series study based on data from the National Immunization Program. Differences between the median number of yellow fever vaccine doses administered in Brazil and in its regions before (from April/2019 to March/2020) and after (from April/2020 to March/2021) the implementation of social distancing measures in the country were assessed via the Mann-Whitney test. Prais-Winsten regression models were used for time series analyses. RESULTS: We found a reduction in the median number of yellow fever vaccine doses administered in Brazil and in its regions: North (-34.71%), Midwest (-21.72%), South (-63.50%), and Southeast (-34.42%) (p < 0.05). Series showed stationary behavior in Brazil and in its five regions during the covid-19 pandemic (p > 0.05). Brazilian states also showed stationary trends, except for two states which recorded an increasing trend in the number of administered yellow fever vaccine doses, namely: Alagoas State (before: ß = 64, p = 0.081; after: ß = 897, p = 0.039), which became a yellow fever vaccine recommendation zone, and Roraima State (before: ß = 68, p = 0.724; after: ß = 150, p = 0.000), which intensified yellow fever vaccinations due to a yellow fever case confirmation in a Venezuelan State in 2020. CONCLUSION: The reduced number of yellow fever vaccine doses administered during the covid-19 pandemic in Brazil may favor the reemergence of urban yellow fever cases in the country.

Self-reported diabetes and factors associated with it in the Brazilian adult population: National Health Survey, 2019. / Diabetes autorreferido e fatores associados na população adulta brasileira: Pesquisa Nacional de Saúde, 2019.

This study aims to analyze the prevalence of self-reported diabetes and its associated factors in the Brazilian adult population. It is a cross-sectional study using the 2019 National Health Survey. Prevalence and crude prevalence ratios (PRc) and adjusted prevalence ratios (PRa) of self-reported diabetes were estimated, with confidence intervals (95% CI), using Poisson regression. In the 82,349 adults, the prevalence of self-reported diabetes was 7.7%. Positively associated factors were: advanced age with greater association after 60 years (PRa 24.87; 95%CI 15.78-39.18); living in the Northeast (PRa 1.16; 95%CI 1.04-1.29), Southeast (PRa 1.27; 95% CI 1.14-1.43), South (PRa 1.18; 95%CI 1, 05-1.34), and Midwest (PRa 1.21; 95%CI 1.06-1.38); being a former smoker (PRa 1.17; 95%CI 1.09-1.27); self-assessment of regular health (PRa 2.41; 95%CI 2.21-2.64), bad/very bad (PRa 3.45; 95%CI 3.06-3.88); having heart disease (PRa 1.81; 95%CI 1.64-2.00), hypertension (PRa 2.84; 95%CI 2.60-3.69), high cholesterol (PRa 2.22; 95%CI 2.05-2.41), overweight (PRa 1.49; 95%CI 1.36-1.64), and obesity (PRa 2.25; 95%CI 2.05-2.47). It could be concluded that diabetes in Brazilian adults is associated with sociodemographic factors, aging, lifestyle, and morbidities. These results can guide public policies for the prevention and control of disease in Brazil.

O estudo analisa a prevalência de diabetes autorreferido e fatores associados na população adulta brasileira. Estudo transversal usando a Pesquisa Nacional de Saúde 2019. Estimaram-se as prevalências e razões de prevalência brutas (RPb) e ajustadas (RPa) de diabetes autorreferido, com intervalos de confiança (IC95%), empregando-se regressão de Poisson. Nos 82.349 adultos, a prevalência de diabetes autorreferido foi de 7,7%. Associaram-se positivamente: idade avançada, sendo maior após 60 anos (RPa 24,87; IC95%: 15,78-39,18); residir nas regiões Nordeste (RPa 1,16; IC95%: 1,04-1,29), Sudeste (RPa 1,27; IC95%: 1,14-1,43), Sul (RPa 1,18; IC95%: 1,05-1,34) e Centro-Oeste (RPa 1,21; IC95%: 1,06-1,38), ser ex-fumante (RPa 1,17; IC95%: 1,09-1,27), autoavaliação de saúde regular (RPa 2,41; IC95%: 2,21-2,64), ruim/muito ruim (RPa 3,45; IC95%: 3,06-3,88), ter doença cardíaca (RPa 1,81; IC95%: 1,64-2,00), hipertensão (RPa 2,84; IC95%: 2,60-3,69), colesterol elevado (RPa 2,22; IC95%: 2,05-2,41), sobrepeso (RPa 1,49; IC95%: 1,36-1,64) e obesidade (RPa 2,25; IC95%: 2,05- 2,47). Conclui-se que o diabetes nos adultos brasileiros se associa a fatores sociodemográficos, envelhecimento, estilos de vida e morbidades. Esses resultados podem orientar políticas públicas para prevenção e controle da doença no Brasil.
