Bolsa Família Program and deaths from oral cancer in Brazil: an ecological study.

Objective: To assess the effect of coverage of the Bolsa Família Program (BFP) on oral cancer mortality rates in Brazil between 2005 and 2017, adjusting for health care coverage and socioeconomic characteristics of the Brazilian federative units. Methods: This is an ecological study using annual data (2005-2017) from all the Brazilian federative units. The dependent variable for this study was the oral cancer mortality rate, standardized by gender and age using the direct standardization technique. BFP coverage was the main independent variable, calculated as the ratio of the number of BFP beneficiaries to those families that should potentially be entitled to this conditional cash transfer. Socioeconomic background and health care coverage were covariables. Choropleth maps were drawn, and space-time cube analysis was used to assess changes in the spatiotemporal distribution of BFP and oral cancer mortality rates. Mixed-effects linear regression analysis estimated the coefficients (ß) and 95% confidence intervals (CI) for the association between BFP coverage and oral cancer mortality rates. Results: BFP coverage trends increased and oral cancer mortality rate trends stabilized in Brazilian federative units, except for Maranhão, Goiás, and Minas Gerais, where the oral cancer mortality rates have increased. In the adjusted model, greater BFP coverage was associated with lower oral cancer mortality rates (ß -2.10; 95% CI [-3.291, -0.919]). Conclusions: Egalitarian strategies such as BFP can reduce the oral cancer mortality rate. We recommend the follow-up of families benefiting from conditional cash transfer program by oral health teams to reduce the oral cancer mortality rate.

Is there a fair distribution of the structure of dental services in the capitals of the Brazilian Federative Units?

BACKGROUND: Brazilian Primary Care Facilities (PCF) provide primary care and must offer dental services for diagnosis, prevention, and treatment of diseases. According to a logic of promoting equity, PCF should be better structured in less developed places and with higher need for oral health services. OBJECTIVE: To analyze the structure of dental caries services in the capitals of the Brazilian Federative Units and identify whether socioeconomic factors and caries (need) are predictors of the oral health services structure. METHODS: This is an ecological study with variables retrieved from different secondary databases, clustered for the level of the federative capitals. Descriptive thematic maps were prepared, and structural equations were analyzed to identify oral health service structure's predictors (Alpha = 5%). Four models with different outcomes related to dental caries treatment were tested: 1) % of PCF with a fully equipped office; 2) % of PCF with sufficient instruments, and 3) % of PCF with sufficient supplies; 4) % of PCF with total structure. RESULTS: 21.6% of the PCF of the Brazilian capitals had a fully equipped office; 46.9% had sufficient instruments, and 30.0% had sufficient supplies for caries prevention and treatment. The four models evidenced proper fit indexes. A correlation between socioeconomic factors and the structure of oral health services was only noted in model 3. The worse the socioeconomic conditions, the lower the availability of dental supplies (standard factor loading: 0.92, P = 0.012). Estimates of total, direct and indirect effects showed that dental caries experience observed in the Brazilian population by SB-Brasil in 2010 did not affect the outcomes investigated. CONCLUSION: Material resources are not equitably distributed according to the socioeconomic conditions and oral health needs of the population of the Brazilian capitals, thus contributing to persistent oral health inequities in the country.

Periodontopathogenic microbiota, infectious mechanisms and preterm birth: analysis with structural equations (cohort-BRISA).

PURPOSE: The association between periodontopathogenic microbiota and preterm birth (PTB) has been overly studied. However, the biological mechanisms involved are little known. The objective is to evaluate the effect of periodontopathogenic bacteria burden (PBB), periodontal disease and other infections during pregnancy on preterm birth (PTB), through Structural Equation Modeling. METHODS: This was a case-control study nested in a prospective cohort called BRISA, including 330 pregnant women, 110 cases and 220 controls. This study included the following variables: cytokines interleukin-10 (IL-10) and transforming growth factor beta (TGF-ß), periodontal disease, PBB, age, socioeconomic status (SES), systemic infections and PTB. The correlations between variables were analyzed using Standardized Coefficient (SC). RESULTS: Greater PBB interfered positively with the occurrence of periodontal disease (SC: 0.027; p: 0.011), but these were not associated with the cytokines studied, nor with PTB. The lower serum levels of IL-10 (SC - 0.330; p 0.022) and TGF-ß (SC - 0.612; p < 0.001), and the presence of other systemic infections during pregnancy (SC 0.159; 0.049) explained the higher occurrence of PTB. CONCLUSION: It is possible that only the more severe periodontal disease and other systemic infections are capable of altering the cascade of cytokines regulating the inflammatory process and have an effect on the occurrence of PTB.

Effect of the COVID-19 pandemic on malnutrition in socially vulnerable children in Brazil. / Efeito da pandemia da COVID-19 sobre a má nutrição em crianças em vulnerabilidade social, no Brasil.

This article aims to evaluate the effect of the COVID-19 pandemic on malnutrition among children under two years of age enrolled in the Bolsa Família Program (BFP). Ecological study of interrupted time series (ITS), with low weight for age, stunting, and overweight as time-dependent variables of malnutrition, extracted monthly (Jan/2008 to June/2021) from the Food and Nutrition Surveillance System. The COVID-19 pandemic was the exposure, dichotomized into pre-pandemic and pandemic. In RStudio, the trend was obtained by Prais-Winsten regression, and the effect of the pandemic on the time-dependent variables was determined by SARIMA modeling, estimating the regression coefficients (RC) adjusted for trend and seasonality (α = 5%). The pandemic was associated with an increase in: i) low weight for age in the South (RC = 0.94; p < 0.001) and Southeast (RC = 1.97; p < 0.001); ii) height deficit in the Midwest (RC = 2.4; p = 0.01), South (RC = 2.15; p < 0.001) and Southeast (RC = 2.96; p < 0.001); and iii) and overweight in the North (RC = 1.51; p = 0.04), Midwest (RC = 2.29; p = 0.01), South (RC = 2.83; p < 0.001), and Southeast (RC = 0.72; p = 0.04). The pandemic increased underweight in the South and Southeast, and the double burden of malnutrition in the Midwest, South, and Southeast. In the Northeast and North, higher rates of malnutrition still persist.

O objetivo do artigo é avaliar o efeito da pandemia de COVID-19 sobre a má nutrição em crianças menores de dois anos inscritas no Programa Bolsa Família. Estudo ecológico de série temporal interrompida, tendo o baixo peso por idade, o déficit de estatura e o excesso de peso como variáveis tempo-dependentes de má nutrição, extraídas mensalmente (jan/2008 a junho/2021) do Sistema de Vigilância Alimentar e Nutricional. A pandemia de COVID-19 foi a exposição, dicotomizada em pré e pandemia. No programa RStudio, a tendência foi obtida pela regressão de Prais-Winsten, e o efeito da pandemia sobre as variáveis tempo-dependentes, pela modelagem SARIMA, calculando-se coeficientes de regressão (CR) ajustados para tendência prévia e sazonalidade (α = 5%). A pandemia se associou ao aumento do: i) baixo peso por idade no Sul (CR = 0,94; p < 0,001) e Sudeste (CR = 1,97; p < 0,001); ii) déficit de estatura no Centro-Oeste (CR = 2,4; p = 0,01), Sul (CR = 2,15; p < 0,001) e Sudeste (CR = 2,96; p < 0,001); e iii) excesso de peso no Norte (CR = 1,51; p=0,04), Centro-Oeste (CR = 2,29; p = 0,01), Sul (CR = 2,83; p < 0,001) e Sudeste (CR = 0,72; p = 0,04). A pandemia aumentou o baixo peso no Sul e Sudeste e a dupla carga de má nutrição no Centro-Oeste, no Sul e no Sudeste. No Nordeste e no Norte persistem taxas mais altas de má nutrição.

Consumption of ultra-processed foods and dental caries in Brazilian adolescents.

This study aimed to evaluate the association between ultra-processed food (UPF) and dental caries, considering muscle mass (MM), bone mineral density (BMD), and oral hygiene habits (OHH) as mediators. This study has an analytical cross-sectional design with 2,515 adolescents (18-19 years). The main exposure - the UPF intake ratio - was established using the food frequency questionnaire. The outcome was the number of decayed teeth, according to the DMFT index. The model adjustment included socio-economic status (SES), frequency of physical activity, and concurrent risk habits (CRH) as potential confounders. Three latent variables were considered: SES (family income, economic class, household head, and adolescent education), OHH (gingival bleeding on probing index and visible plaque index), and CRH (alcohol and tobacco dependence). The analyses used structural equation modeling, estimating the standardized coefficient (SC) in three models: lumbar BMD(1), femoral BMD(2), and total BMD(3). UPF consumption had a direct (SCmodel1=0.071, SCmodel2=0.072, SCmodel3=0.071; p < 0.05) and total (SCmodel1=0.067, SCmodel2=0.068, SCmodel3=0.068; p < 0.05) effect on the number of decayed teeth. BMD and MM did not mediate the association between UPF and dental caries, but the indirect association mediated by OHH was significant in all analyses (p < 0.05). Dental Caries was explained in other specific pathways: SES→UPF→Dental Caries (SCmodel1 = 0.009, SCmodel2 = 0.008, SCmodel3 = 0.009); SES→OHH→Dental Caries (SCmodel1 = 0.033, SCmodel2 = 0.033, SCmodel3 = 0.034); CRH→UPF→Dental Caries (SCmodel1 = 0.009, SCmodel2 = 0.008, SCmodel3 = 0.008); CRH→OHH→Dental Caries (SCmodel1 = 0.029, SCmodel2 = 0.027, SCmodel3 = 0.027). Dental caries prevention should include encouraging good OHH, healthy eating, and developing equitable public policies in middle and low-income countries like Brazil.

Spatial analysis of hospital-related mortality due to COVID-19 among children and adolescents in Brazil.

The objective was to perform a spatial analysis of the hospital mortality rate (HMR) due to severe acute respiratory syndrome (SARS) attributed to COVID-19 among children and adolescents in Brazil from 2020 to 2021. A cluster method was used to group federal units (FUs) based on HMR. In 2020, clusters with high HMRs were formed by north/northeast FUs. In 2021, there was a reduction in HMR. Clusters with higher rates remained in the N/NE region. Regional differences were observed in the HMR. The findings may reflect social inequalities and access to hospital care, especially in the under 1-year-old age group due to the severity of the disease in this group.

The Brazilian National Oral Health Policy and oral cancer mortality trends: An autoregressive integrated moving average (ARIMA) model.

OBJECTIVE: This study analyzes the effect of the Brazilian National Oral Health Policy (NOHP) on oral cancer mortality rates (OCMR). METHOD: This is an ecological study with secondary oral cancer death data, using interrupted time series analysis (ARIMA, Autoregressive Integrated Moving Average). Annual death data were collected from the Mortality Information System (1996-2019). The outcome was the OCMR, standardized by gender and age We considered the NOHP, categorized as "0" (before its implementation), from 1996 to 2004, and "1 to 15", from 2005 to 2019. ARIMA modeling was carried out for temporal analysis, and regression coefficient estimation (RC). RESULTS: The Brazilian NOHP implementation was associated with an increase in OCMR in the North region (CR = 0.16; p = 0.022) and with a decrease in the Southeast region (CR = -0.04; p<0.001), but did not affect the other macro-regions nor Brazil. The forecast models estimated an increase in OCMR for the North, and Northeast, a decrease for the Southeast, and stability for the South and Brazil. CONCLUSION: The Brazilian NOHP is not being effective in reducing the OCMR. The trends behaved differently in the Brazilian territory, highlighting health inequities. We recommend that the NOHP strengthen the oral health care network, incorporating oral cancer as a notifiable disease, adopting strategies for prevention, screening, and providing opportunities for early treatment of the disease.

RANTES and developmental defects of enamel in children: A Brazilian prenatal cohort (BRISA).

OBJECTIVE: Little is known about the effect of maternal immunological factors on the etiology of developmental defects of enamel (DDE). RANTES (Regulated on Activation Normal T Cell Expressed and Secreted) is a chemokine produced by fibroblasts, lymphoid and epithelial mucosa cells in response to various external stimuli. Despite its importance for embryogenesis, RANTES expression has been demonstrated in multiple diseases characterized by inflammation, tumor and immune response, and wound healing. We hypothesized that altered levels of RANTES during pregnancy are associated with the immune and inflammatory response in women, which could lead to the occurrence of DDE in utero (DDE-iu), directly or mediated by preterm birth. Therefore, this study aimed to evaluate the direct and indirect effects of serum levels of RANTES in pregnant women in the occurrence of DDE-iu in children. METHODS: This is a longitudinal case-control study. The mothers and their children (327) were evaluated in three moments: prenatal care, post childbirth, and when the child was between 12.3 and 36 months of age. The analysis was performed with structural equation modeling, estimating the standardized coefficient (SC), adopting α = 5%. RESULTS: There was a direct and negative effect of RANTES on the outcome (SC = -0.137; p = 0.022). This association was not mediated by preterm birth (SC = 0.007; P = 0.551). When considering the specific types of DDE-iu, RANTES had a direct effect on hypoplasia (SC = -0.190; p = 0.007), but not on opacity (SC = 0.343; p = 0.074). CONCLUSION: Lower serum levels of RANTES may contribute to a higher number of teeth with DDE-iu, specifically hypoplasia. However, more evidence supported by clinical, laboratory and epidemiological studies is still needed.

A Cross-Sectional Study of the Association Between Chronic Oral Disease Burden and Serum Biomarkers in Kidney Transplant Recipients.

INTRODUCTION: Poor oral health can negatively affect general health and quality of life of kidney transplant recipients. The study aimed to investigate the association between chronic oral disease burden, serum biomarkers, and comorbidities in kidney transplant recipients. DESIGN: A cross-sectional comparative study was conducted with 44 patients after kidney transplant. The burden of chronic oral disease was composed of the following observable variables: moderate periodontitis and presence of dental caries. Serum biomarkers and comorbidities data were collected. The chi-square or Fisher's exact tests for categorical variables and Student's t-test or Mann-Whitney test for continuous variables were used. Robust Poisson regression was used to model the association. RESULTS: Higher levels of mean uric acid (P = .01) and creatinine (P = .03) were observed in the group of patients with oral disease burden, while the highest level of high-density lipoprotein was observed in the group without oral disease. Higher values of uric acid were associated with the occurrence of chronic oral disease burden (Adjusted PR = 1.24, 95% CI: 1.03-1.48, P = .019). There was no statistical difference between the groups with and without oral disease burden in comorbidities present. CONCLUSION: The findings suggest that chronic oral diseases burden can be associated with uric acid and creatinine levels in kidney transplant recipients.

Advances and weaknesses of the work process of the oral cancer care network in Brazil: A latent class transition analysis.

OBJECTIVE: To analyse the provision of oral cancer (OC) care services in the Dental Specialties Centers (Centros de Especialidades Odontológicas-CEO) in Brazil and identify changes over two cycles of external evaluation of the Program for the Improvement of Access and Quality-PMAQ, in 2014 and 2018. METHOD: This is a nationwide panel ecological study, including 916 CEO. Data from interviews with managers and dentists of the CEO were used, including variables related to training on OC, clinical protocols, biopsies, referral for diagnosis and treatment, and registration of users with OC. We carried out Latent Transition Analysis (LTA) to identify patterns (latent status LS) of service adequacy and work processes' changes between the two assessment cycles. We tested models with three, four, and five LS, selecting the one with the best conceptual interpretability and good model fit parameters. Data from the LS were plotted on choropleth and hotspots maps in Brazil allowing us to identify areas with the better or worse provision of specialized OC services. RESULTS: The model with four LS was chosen. The four LS were named: 1.'Most indicators inadequate for OC care' (the worst); 2. 'Most indicators suitable for OC care' (the best); 3. 'CEO with a poor relation with Primary Health Care (PHC) services'; and 4. 'CEO with a poor relation with tertiary hospital services'. The comparison of the LS transition between the two cycles revealed that 419 (45.7%) CEO remained in the same LS (1→1, 3→4, 2→2); 228 (24.9%) switched to a worse status (2→1, 2→4, 3→1) and 269 (29.4%) switched to a better LS (1→2, 1→4, 3→2). While the majority of the CEO improved, we identified a decline of 17.8% in those who reported performing biopsies and 18.3% in the number of CEO that had hospitals for referring confirmed OC cases. Almost all Brazilian states had CEO that improved the work process. The Southeast and South regions had the highest percentage of CEO with the better work process in both cycles. Hotspots showed areas concentrating improvements in the work process in the Northeast region. However, some hotspots in the North revealed some CEO where the work process deteriorated or remained unsatisfactory. CONCLUSIONS: There are regional inequities in the provision of OC care in CEO. Most services improved their work process or remained stable. However, the biopsies and the referral to hospital care for confirmed cases declined, indicating that CEO need to improve planning and care provision to reduce OC morbimortality.

Accessibility to people with motor, visual, or hearing disabilities during delivery and childbirth: the structure of SUS facilities linked to Rede Cegonha. / Acessibilidade no parto e nascimento a pessoas com deficiência motora, visual ou auditiva: estrutura de estabelecimentos do SUS vinculados à Rede Cegonha.

There are no nationwide studies characterizing accessibility for people with disabilities during delivery. This study aimed to describe the physical structure of hospital units regarding accessibility for pregnant and puerperae with motor (MD), visual (VD), or hearing (HD) disabilities in Brazil. This is an ecological, descriptive study conducted in all 606 health facilities linked to the "Rede Cegonha" where deliveries occurred, according to 2015 databases. We performed the descriptive and geospatial analysis and considered the presence of motor accessibility when the establishment had a handrail or elevator ramp, wheelchair-sized doors, and accessible bathroom with bars. We assumed visual accessibility when there was tactile signage on the floor (Braille system or embossed figures) and hearing accessibility when there was signage by texts, pictures, signs, posters, or symbols in the environments. In Brazil, only 26 (4.3%) of the facilities had accessibility for people with MD, 20 (3.3%) for people with VD, and none for HD. Motor accessibility was worse in the North and Northeast of Brazil, and hearing accessibility in the North region. Despite advances in the implementation of the "Rede Cegonha" in Brazil, the facilities' structure is not adapted for women with MD, VD, or HD.

Não há estudos, de abrangência nacional, caracterizando a acessibilidade para pessoas com deficiência no momento do parto. O objetivo do estudo foi descrever a estrutura física de estabelecimentos hospitalares quanto à acessibilidade para gestantes e puérperas com deficiência motora (DM), visual (DV) ou auditiva (DA) no Brasil. Estudo ecológico, descritivo, realizado em todos os 606 estabelecimentos vinculados à Rede Cegonha (RC), que realizaram partos em 2015. Foram feitas análises descritivas e de distribuição espacial. Considerou-se acessibilidade motora quando o estabelecimento tivesse rampa com corrimão ou elevador, portas com dimensões para cadeira de rodas e banheiro acessível com barras; acessibilidade visual quando houvesse sinalização tátil (sistema Braille ou figuras em relevo); e acessibilidade auditiva quando houvesse sinalização por textos, figuras, placas, cartazes ou símbolos nos ambientes. No Brasil, apenas 26 (4,3%) estabelecimentos tinham acessibilidade para pessoas com DM, 20 (3,3%) para pessoas com DA e nenhum para pessoas com DV. A acessibilidade motora foi pior no Norte e Nordeste e a auditiva, no Norte. Apesar dos avanços decorrentes da implantação da RC no Brasil, a estrutura dos estabelecimentos hospitalares não está adaptada para pessoas com DM, DV ou DA.

Do social inequalities persist in the distribution of dental caries in adolescents from Maranhão? Contributions of a population-based study. / Persistem iniquidades sociais na distribuição da cárie dentária em adolescentes maranhenses? Contribuições de um estudo de base populacional.

This study aimed to analyze the association of socioeconomic factors with the prevalence of dental caries in adolescents from São Luís, Maranhão, Brazil, to answer whether social inequalities persist in distributing this disease. This is a cross-sectional study nested in a prospective cohort. We included 2,413 adolescents aged 18-19 years evaluated in the 2016 second follow-up. The outcome was teeth with untreated dental caries (yes or no) assessed by the DMFT index. Socioeconomic and demographic characteristics were the independent variables. Descriptive statistical and Poisson regression analyses were performed, calculating crude and adjusted prevalence ratios (PRs) (alpha=5%). Belonging to economic classes C (PR=1.23; 95% CI: 1.11-1.37) or D-E (PR=1.48; 95% CI: 1.32-1.65), being married/living with a partner (PR=1.22; 95% CI: 1.07-1.39), having separated parents (PR=1.11; 95% CI 1.03-1.19) and a greater number of people in the household (PR=1.05; 95% CI: 1.03-1.07) were associated with a higher prevalence of dental caries. Social inequalities in adolescent oral health persist despite the implementation of the National Oral Health Policy. The current health care model should seek to reorient health education strategies, targeting them at vulnerable populations.

O objetivo foi analisar a associação de fatores socioeconômicos com a prevalência de cárie dentária em adolescentes de São Luís, Maranhão, para responder se as iniquidades sociais persistem na distribuição desta doença. Este é um estudo transversal aninhado a uma coorte prospectiva. Incluímos 2.413 adolescentes de 18-19 anos, avaliados em 2016 (2º seguimento). O desfecho foi a ocorrência de dentes com cárie dentária não tratada (sim ou não), avaliada pelo índice CPO-D. Características socioeconômicas e demográficas foram as variáveis independentes. Foram realizadas análises estatísticas descritivas e de regressão de Poisson, calculando-se razões de prevalência (RPs) brutas e ajustadas (alpha=5%). Pertencer às classes econômicas C (RP=1,23; IC95%:1,11-1,37) ou D-E (RP=1,48; IC95%: 1,32-1,65), estar casado/morar com companheiro (RP=1,22; IC95%:1,07-1,39), ter pais separados (RP=1,11; IC95%1,03-1,19) e maior número de pessoas na residência (RP=1,05; IC95%:1,03-1,07) foram associadas a maior prevalência de cárie dentária. Apesar da implementação da Política Nacional de Saúde Bucal, as iniquidades sociais em saúde bucal de adolescentes persistem. É fundamental que o modelo de atenção à saúde vigente busque a reorientação das estratégias de educação em saúde, direcionando-as a populações vulneráveis.

Efeito da pandemia da COVID-19 sobre a má nutrição em crianças em vulnerabilidade social, no Brasil / Effect of the COVID-19 pandemic on malnutrition in socially vulnerable children in Brazil

Resumo O objetivo do artigo é avaliar o efeito da pandemia de COVID-19 sobre a má nutrição em crianças menores de dois anos inscritas no Programa Bolsa Família. Estudo ecológico de série temporal interrompida, tendo o baixo peso por idade, o déficit de estatura e o excesso de peso como variáveis tempo-dependentes de má nutrição, extraídas mensalmente (jan/2008 a junho/2021) do Sistema de Vigilância Alimentar e Nutricional. A pandemia de COVID-19 foi a exposição, dicotomizada em pré e pandemia. No programa RStudio, a tendência foi obtida pela regressão de Prais-Winsten, e o efeito da pandemia sobre as variáveis tempo-dependentes, pela modelagem SARIMA, calculando-se coeficientes de regressão (CR) ajustados para tendência prévia e sazonalidade (α = 5%). A pandemia se associou ao aumento do: i) baixo peso por idade no Sul (CR = 0,94; p < 0,001) e Sudeste (CR = 1,97; p < 0,001); ii) déficit de estatura no Centro-Oeste (CR = 2,4; p = 0,01), Sul (CR = 2,15; p < 0,001) e Sudeste (CR = 2,96; p < 0,001); e iii) excesso de peso no Norte (CR = 1,51; p=0,04), Centro-Oeste (CR = 2,29; p = 0,01), Sul (CR = 2,83; p < 0,001) e Sudeste (CR = 0,72; p = 0,04). A pandemia aumentou o baixo peso no Sul e Sudeste e a dupla carga de má nutrição no Centro-Oeste, no Sul e no Sudeste. No Nordeste e no Norte persistem taxas mais altas de má nutrição.

Abstract This article aims to evaluate the effect of the COVID-19 pandemic on malnutrition among children under two years of age enrolled in the Bolsa Família Program (BFP).

The pandemic increased underweight in the South and Southeast, and the double burden of malnutrition in the Midwest, South, and Southeast. In the Northeast and North, higher rates of malnutrition still persist.

Spatial analysis of hospital-related mortality due to COVID-19 among children and adolescents in Brazil / Análise espacial da mortalidade hospitalar por COVID-19 em crianças e adolescentes no Brasil

Abstract The objective was to perform a spatial analysis of the hospital mortality rate (HMR) due to severe acute respiratory syndrome (SARS) attributed to COVID-19 among children and adolescents in Brazil from 2020 to 2021. A cluster method was used to group federal units (FUs) based on HMR. In 2020, clusters with high HMRs were formed by north/northeast FUs. In 2021, there was a reduction in HMR. Clusters with higher rates remained in the N/NE region. Regional differences were observed in the HMR. The findings may reflect social inequalities and access to hospital care, especially in the under 1-year-old age group due to the severity of the disease in this group.

Resumo Objetivou-se realizar uma análise espacial da taxa de mortalidade hospitalar (TMH) por síndrome respiratória aguda grave (SRAG) atribuída à COVID-19 em crianças e adolescentes no Brasil no período de 2020 a 2021. Utilizou-se o método de cluster para agrupar as unidades federativas (UFs) com base na TMH. Em 2020, clusters com altas TMHs foram formados por UFs Norte/Nordeste. Em 2021, houve redução na TMH. Os clusters com maiores taxas permaneceram na região N/NE. Diferenças regionais foram observadas nas TMHs. Os achados podem refletir as desigualdades sociais e o acesso à atenção hospitalar, principalmente na faixa etária de menores de 1 ano pela gravidade da doença neste grupo.

Efeitos da pandemia de COVID-19 nos serviços odontológicos da atenção primária no Maranhão, Brasil / Effects of the COVID-19 pandemic on dental services in primary care in Maranhão, Brazil

Resumo O objetivo deste artigo é analisar indicadores de uso de serviços de saúde bucal da atenção primária à saúde no Maranhão antes e durante a pandemia de COVID-19. Estudo ecológico de série temporal interrompida cuja unidade de análise foi o Maranhão. A exposição foi a pandemia de COVID-19, dicotomizada em pré e pandemia. Os desfechos foram calculados pela razão da quantidade de procedimentos preventivos (RPP), de urgência (RPU) e procedimentos curativos (RPC), e a projeção censitária da população do estado, multiplicada por mil, mensalmente. Os dados foram coletados do Sistema de Informação em Saúde para a Atenção Básica e do Instituto Brasileiro de Geografia e Estatística, no período de 2015.1 a 2022.2. As análises foram realizadas por meio do modelo autorregressivo, integrado e de médias móveis com sazonalidade. Houve tendência crescente dos três indicadores até jan./2019. A pandemia causou redução significativa na RPP (Xreg = -6,55; p-valor = 0,0008) e na RPC (Xreg = -4,74; p-valor = 0,0005), mas não influenciou a RPU (Xreg = -0,03; p-valor = 0,12) desde o primeiro semestre de 2020, persistindo até o segundo semestre de 2022. A pandemia de COVID-19 provocou redução nos serviços preventivos e curativos de saúde bucal no Maranhão.

Abstract This article aims to analyze indicators of the utilization of oral health services (UOHS) in primary health care in the state of Maranhão, Brazil, before and during the COVID-19 pandemic. We conducted an ecological time series study. The unit of analysis was the state of Maranhão, and the exposure variable was the COVID-19 pandemic, dichotomized into pre-pandemic and pandemic. The outcome variables were the monthly rates per 1,000 population of three UOHS indicators: rate of preventive procedures (RPP-PHC); rate of urgent procedures (RUP-PHC), and rate of curative procedures (RCP-PHC). The data were collected from the Primary Health Care Information System (SISAB) and the Brazilian Institute of Geography and Statistics (IBGE) for the period from 2015-2022. The analyses were performed using the Seasonal Autoregressive Integrated Moving Average (SARIMA) model. The three indicators showed an upward trend up to January 2019. The pandemic caused a significant reduction in the RPP (Xreg = -6.55; p-value = 0.0008) and RCP (Xreg = -4.74; p-value = 0.0005), starting in the first semester of 2020 and continuing into the second semester of 2022, but did not influence the RUP (Xreg = -0.03; p-value = 0.12). The COVID-19 pandemic caused a reduction in preventive and curative oral health services in Maranhão.

Anemia and Dental Caries in Pregnant Women: a Prospective Cohort Study.

The objective was to evaluate the effect of anemia during pregnancy on the risk of dental caries development in pregnant women. A prospective cohort including a sample of pregnant women in a prenatal care unit of São Luís, Brazil, was done. The incidence of dental caries during pregnancy, according to Nyvad's criteria, was the outcome. The main independent variables were serum iron, ferritin, hemoglobin, erythrocyte, hematocrit, mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), and red cell distribution width (RDW). Pregnant women (n = 121) were evaluated at two moments: up to 16th week of gestational age (T1) and in the last trimester of pregnancy (T2). Crude and adjusted associations were estimated by the incidence ratio risk (IRR) and respective 95% confidence intervals (95%CI). After adjustment, higher serum concentrations of ferritin (IRR = 0.97, 95%CI 0.95-0.99) in T1, and Fe (IRR = 0.99, 95%CI 0.98-0.99), ferritin (IRR = 0.99, 95%CI 0.98-0.99), erythrocyte (IRR = 0.71, 95%CI 0.50-0.99), hemoglobin (IRR = 0.84, 95%CI 0.73-0.96), hematocrit (IRR = 0.93, 95%CI 0.88-0.98), MCV (IRR = 0.91, 95%CI 0.86-0.96), and MCH (IRR = 0.83, 95%CI 0.74-0.93) in T2, were associated with fewer incidence of dental caries in pregnant women. Iron deficiency anemia during pregnancy is a risk factor for the incidence of dental caries in these women.

Salivary Iron (Fe) Ion Levels, Serum Markers of Anemia and Caries Activity in Pregnant Women.

Introduction Anemia is a very frequent event among pregnant women. There are evidences of differences in the incidence of dental caries between pregnant and non-pregnant women, but the relationship between salivary iron (Fe) and serum markers of anemia and caries development has not been investigated. Objective To evaluate the correlation between salivary (Fe) and serum iron (Fe, ferritin and hemoglobin) parameters in pregnant women with the development of dental caries. Methods A prospective cohort was conducted with 59 women. The outcome of interest was represented by new dental caries lesions during pregnancy, using the Nyvad criteria. Pregnant women were evaluated at three clinical times: up to the 16th week of gestational age (GA) (T1), in the last trimester of pregnancy (T2), and postpartum (T3), at the Mother and Child Unit of University Hospital of the Universidade Federal do Maranhão. A stimulated saliva sample was collected for biochemical analysis of salivary Fe, and a blood sample was collected early in the morning. The correlation between salivary and serum Fe was evaluated through the Pearson correlation test. Analysis of variance (ANOVA) and Kruskal-Wallis were used to compare the means of anemia parameters at different times. The Student's t and Mann-Whitney tests were used to compare the anemia parameters between the groups of pregnant women (with and without new caries lesions). Results Serum Fe concentrations were higher in the first trimester of pregnancy and lower after delivery (p = 0.036). It was also observed that the ferritin concentrations were higher in the first trimester and lower at the end of gestation (p = 0.011). There was no association between the expositions of salivary iron and anemia, and the development of dental caries. There was a positive correlation between serum Fe in T1 and salivary Fe in T2 (p < 0.05). Conclusion The serum markers of anemia were more prevalent in the last trimester of pregnancy.

Bolsa Família Program and deaths from oral cancer in Brazil: an ecological study

[ABSTRACT]. Objective. To assess the effect of coverage of the Bolsa Família Program (BFP) on oral cancer mortality rates in Brazil between 2005 and 2017, adjusting for health care coverage and socioeconomic characteristics of the Brazilian federative units. Methods. This is an ecological study using annual data (2005–2017) from all the Brazilian federative units. The dependent variable for this study was the oral cancer mortality rate, standardized by gender and age using the direct standardization technique. BFP coverage was the main independent variable, calculated as the ratio of the number of BFP beneficiaries to those families that should potentially be entitled to this conditional cash transfer. Socioeconomic background and health care coverage were covariables. Choropleth maps were drawn, and space-time cube analysis was used to assess changes in the spatiotemporal distribution of BFP and oral cancer mortality rates. Mixed-effects linear regression analysis estimated the coefficients (β) and 95% confidence intervals (CI) for the association between BFP coverage and oral cancer mortality rates. Results. BFP coverage trends increased and oral cancer mortality rate trends stabilized in Brazilian federative units, except for Maranhão, Goiás, and Minas Gerais, where the oral cancer mortality rates have increased. In the adjusted model, greater BFP coverage was associated with lower oral cancer mortality rates (β –2.10; 95% CI [–3.291, –0.919]). Conclusions. Egalitarian strategies such as BFP can reduce the oral cancer mortality rate. We recommend the follow-up of families benefiting from conditional cash transfer program by oral health teams to reduce the oral cancer mortality rate.

[RESUMEN]. Objetivo. Evaluar el efecto de la cobertura del Programa Bolsa Família (BFP) en las tasas de mortalidad por cáncer de la cavidad bucal en Brasil entre el 2005 y el 2017, ajustadas por cobertura de atención de salud y características socioeconómicas de las unidades federativas brasileñas. Métodos. Este es un estudio ecológico con datos anuales (2005-2017) de todas las unidades federativas brasileñas. La variable dependiente de este estudio fue la tasa de mortalidad por cáncer de la cavidad bucal, estandarizada por sexo y edad mediante la técnica de estandarización directa. La cobertura del BFP fue la principal variable independiente, calculada como la relación entre el número de beneficiarios del BFP y las familias que podrían tener el derecho a recibir esta transferencia monetaria condicionada. Los antecedentes socioeconómicos y la cobertura de atención de salud fueron covariables. Se trazaron mapas coropléticos y se realizó un análisis con cubos espaciotemporales para evaluar los cambios en la distribución espaciotemporal del BFP y las tasas de mortalidad por cáncer de la cavidad bucal. El análisis de regresión lineal de efectos mixtos calculó los coeficientes (β) y los intervalos de confianza (IC) del 95% para la relación entre la cobertura del BFP y las tasas de mortalidad por cáncer de la cavidad bucal. Resultados. Las tendencias de cobertura del BFP aumentaron y las tendencias de la tasa de mortalidad por cáncer de la cavidad bucal se estabilizaron en las unidades federativas brasileñas, excepto en Maranhão, Goiás y Minas Gerais, donde estas tasas aumentaron. En el modelo ajustado, una mayor cobertura del BFP se asoció con tasas más bajas de mortalidad por cáncer de la cavidad bucal (β –2,10; IC del 95% [–3,291, –0,919]). Conclusiones. Las estrategias igualitarias como el BFP pueden reducir la tasa de mortalidad por cáncer de la cavidad bucal. Recomendamos el seguimiento por parte de los equipos de salud bucodental de las familias que se benefician del programa de transferencias monetarias condicionadas para reducir la tasa de mortali- dad por cáncer de la cavidad bucal.

Acessibilidade no parto e nascimento a pessoas com deficiência motora, visual ou auditiva: estrutura de estabelecimentos do SUS vinculados à Rede Cegonha / Accessibility to people with motor, visual, or hearing disabilities during delivery and childbirth: the structure of SUS facilities linked to Rede Cegonha

Resumo Não há estudos, de abrangência nacional, caracterizando a acessibilidade para pessoas com deficiência no momento do parto. O objetivo do estudo foi descrever a estrutura física de estabelecimentos hospitalares quanto à acessibilidade para gestantes e puérperas com deficiência motora (DM), visual (DV) ou auditiva (DA) no Brasil. Estudo ecológico, descritivo, realizado em todos os 606 estabelecimentos vinculados à Rede Cegonha (RC), que realizaram partos em 2015. Foram feitas análises descritivas e de distribuição espacial. Considerou-se acessibilidade motora quando o estabelecimento tivesse rampa com corrimão ou elevador, portas com dimensões para cadeira de rodas e banheiro acessível com barras; acessibilidade visual quando houvesse sinalização tátil (sistema Braille ou figuras em relevo); e acessibilidade auditiva quando houvesse sinalização por textos, figuras, placas, cartazes ou símbolos nos ambientes. No Brasil, apenas 26 (4,3%) estabelecimentos tinham acessibilidade para pessoas com DM, 20 (3,3%) para pessoas com DA e nenhum para pessoas com DV. A acessibilidade motora foi pior no Norte e Nordeste e a auditiva, no Norte. Apesar dos avanços decorrentes da implantação da RC no Brasil, a estrutura dos estabelecimentos hospitalares não está adaptada para pessoas com DM, DV ou DA.

Abstract There are no nationwide studies characterizing accessibility for people with disabilities during delivery. This study aimed to describe the physical structure of hospital units regarding accessibility for pregnant and puerperae with motor (MD), visual (VD), or hearing (HD) disabilities in Brazil. This is an ecological, descriptive study conducted in all 606 health facilities linked to the "Rede Cegonha" where deliveries occurred, according to 2015 databases. We performed the descriptive and geospatial analysis and considered the presence of motor accessibility when the establishment had a handrail or elevator ramp, wheelchair-sized doors, and accessible bathroom with bars. We assumed visual accessibility when there was tactile signage on the floor (Braille system or embossed figures) and hearing accessibility when there was signage by texts, pictures, signs, posters, or symbols in the environments. In Brazil, only 26 (4.3%) of the facilities had accessibility for people with MD, 20 (3.3%) for people with VD, and none for HD. Motor accessibility was worse in the North and Northeast of Brazil, and hearing accessibility in the North region. Despite advances in the implementation of the "Rede Cegonha" in Brazil, the facilities' structure is not adapted for women with MD, VD, or HD.
