Time trend and costs of hospitalizations with diabetes mellitus as main diagnosis in the Brazilian National Health System, 2011 to 2019.

OBJECTIVE: To analyze the diabetes mellitus (DM) temporal trend and hospitalization costs in Brazil, by region, Federative Units (FUs) and population characteristics, from 2011 to 2019. METHODS: This was an ecological study with data from the Hospital Information System, analyzing the annual trend in hospitalization rates for DM according to sex, age, race/skin color and region/FU by Prais-Winsten generalized linear regression. RESULTS: A total of 1,239,574 DM hospitalizations were recorded in the country and the hospitalization rates was 6.77/10,000 inhabitants in the period. The DM hospitalization rates trend was falling for both sexes and in most regions, while it was rising in the younger population and for length of stay (average 6.17 days). Total expenditure was US$ 420,692.23 and it showed a rising trend. CONCLUSION: The temporal trend of hospitalization rates due to DM was falling, with differences according to region/FU and age group. Average length of stay and expenditure showed a rising trend. MAIN RESULTS: From 2011 to 2019, the diabetes mellitus hospitalization rate was 6.77 per 10,000 inhabitants, with a falling trend. Total expenditure was US$420,692.23 and it showed a rising trend. IMPLICATIONS FOR SERVICES: The study warns of the increase in child and adolescent hospitalizations, which indicates the need to invest in preventive actions and early diagnosis. PERSPECTIVES: The increase in length of hospital stay and related costs indicates a worrying scenario for the Brazilian National Health System and emphasizes the need to improve access to and quality of care, with a focus on diabetes education, so as to avoid complications and hospitalizations.

A portrait of gestational diabetes mellitus in Brazil: A systematic review and meta-analysis.

The diagnostic criteria for gestational diabetes mellitus (GDM), a transient hyperglycemic state during pregnancy, has varied remarkably over time, resulting in a diversity of prevalence rates. The aim of this systematic literature review was to provide estimates of prevalence rates of GDM in Brazil according to different diagnostic criteria. We identified, reviewed, and extracted data from the scientific literature on studies estimating the prevalence of diabetes in pregnant women living in Brazil. The databases searched were PubMed, LILACS, SciELO, Embase, Web of Science, and Cochrane Library. We grouped studies by the source of information assessing GDM, patients' age, and criteria used to diagnose GDM. When three or more studies were available in a group, we calculated the pooled prevalence. The Joanna Briggs Institute (JBI) appraisal tool was used to assess the risk of bias. The data were reported according to the 2020 PRISMA recommendations. The study protocol was registered in PROSPERO. We identified 1,328 records and selected 21 studies involving 122,635 pregnant women. Studies in adults only, with primary data and laboratory measurements, and using the IADPSG criteria (n = 3) had a GDM prevalence of 18.0% (95% confidence interval [CI]: 16.0-20.1%) and included 6,243 participants. Estimates of self-reported GDM (n = 3; 10,136 participants of all ages) had a pooled GDM prevalence of 2.1% (95% CI: 1.5-5.2%), with high heterogeneity (I2 = 85.0%, p < 0.01). Studies including adolescents had consistently low prevalences. The prevalence of GDM in Brazil varied, was greater when the IADPSG criteria were applied, and depended on the methods used to obtain the GDM information and the age structure of the sample.

Infecção materna por SARS-CoV-2: descrição das notificações em gestantes / Maternal infection by SARS-CoV-2: description of notifications in pregnant women

Objetivo: Caracterizar as notificações de infecção por SARS-CoV-2 em gestantes em um município do sul de Santa Catarina. Métodos: Estudo transversal que avaliou as notificações de casos suspeitos de infecção por SARS-CoV-2 em gestantes no município de Tubarão, Santa Catarina, de março de 2020 a outubro de 2021. Coletaram-se os dados das fichas de notificação de infecção por SARS-CoV-2 da Fundação Municipal de Saúde e no Prontuário Eletrônico do Cidadão (PEC) das gestantes notificadas. A comparação da prevalência de confirmação segundo sintomas apresentados e características maternas foi realizada pela razão de prevalência (RP), com intervalo de confiança (IC) de 95%. Resultados: Foram registradas 555 notificações de gestantes suspeitas para a COVID-19, correspondentes a 487 mulheres. A prevalência de confirmação para a doença foi de 27,3%. O sintoma mais frequente no momento da notificação foi cefaleia (53,0%), entretanto o mais associado à confirmação foi a anosmia (RP: 2,28; IC 95%: 1,68-3,09). Das notificações registradas, 35,0% foram realizadas por gestantes que tiveram contato com casos suspeitos ou confirmados de COVID-19. O contato prévio foi mais relatado por gestantes assintomáticas, em comparação às gestantes que apresentaram sintomas (RP: 1,46; IC 95%: 1,12-1,91). Mulheres que relataram contato prévio com suspeitos ou confirmados para a COVID-19 apresentaram maior frequência de doença confirmada, quando comparadas às gestantes não expostas (RP: 1,80; IC 95%: 1,35-2,39). Conclusão: As gestantes, por terem maior susceptibilidade a surtos de doenças e gravidade do quadro, podem ter adotado com mais atenção medidas como a realização de testes diagnósticos quando em contato prévio com casos de COVID-19, mesmo assintomáticas.

Objective: To characterize the notifications of SARS-CoV-2 infection in pregnant women in a city in the South of Santa Catarina. Methods: Cross-sectional study that evaluated notifications of suspected cases of SARS-CoV-2 infection in pregnant women in the municipality of Tubarão, Santa Catarina, from March 2020 to October 2021. Data were collected from the SARS-CoV-2 infection notification forms from the Municipal Health Foundation, and from the Citizen's Electronic Health Record of the notified pregnant women. The comparison of the prevalence of confirmation according to symptoms and maternal characteristics was performed using the Prevalence Ratio (PR), with a confidence interval (CI) of 95%. Results: 555 notifications of suspected pregnant women for COVID-19 were registered, corresponding to 487 women. The prevalence of confirmation for the disease was 27.3%. The most frequent symptom at the time of notification was headache (53.0%), however, the most associated with confirmation was anosmia (PR: 2.28; 95% CI: 1.68-3.09). Of the notifications registered, 35.0% were made by pregnant women who had contact with suspected or confirmed cases of COVID-19. The previous contact was more frequently reported by asymptomatic pregnant women compared to pregnant women who had symptoms (PR: 1.46; 95% CI: 1.12-1.91). Women who reported previous contact with suspected or confirmed COVID-19 had a higher frequency of confirmed disease when compared to unexposed pregnant women (PR: 1.80; 95% CI: 1.35-2.39). Conclusion: Pregnant women, due to their greater susceptibility to disease outbreaks and disease severity, may have adopted more attentive measures such as diagnostic testing in the face of previous contact with cases of COVID-19, even if asymptomatic.

Aedes aegypti in Southern Brazil: Spatiotemporal Distribution Dynamics and Association with Climate and Environmental Factors.

In Brazil, the mosquito Aedes (Stegomyia) aegypti is considered the main vector of the dengue, chikungunya, and Zika arbovirus transmission. Recent epidemiological studies in southern Brazil have shown an increase in the incidence of dengue, raising concerns over epidemiological control, monitoring, and surveys. Therefore, this study aimed at performing a historical spatiotemporal analysis of the Ae. aegypti house indices (HI) in southern Brazil over the last 19 years. As vector infestation was associated with climatic and environmental variables, HI data from the Brazilian Ministry of Health, climate data from the Giovanni web-based application, and environmental data from the Mapbiomas project were used in this study. Our results showed an expressive increase in the number of HI surveys in the municipalities confirming the vector presence, as compared to those in 2017. Environmental variables, such as urban infrastructure, precipitation, temperature, and humidity, were positively correlated with the Ae. aegypti HI. This was the first study to analyze Ae. aegypti HI surveys in municipalities of southern Brazil, and our findings could help in developing and planning disease control strategies to improve public health.

Dental visits and depression mediating the association of socioeconomic status with oral health behaviors.

Determinants of oral diseases include behaviors, which in turn are influenced by a series of social determinants such as psychosocial aspects and dental care services. Therefore, the aim of this study was to investigate whether depressive symptoms and use of dental care services mediate the relationship between socioeconomic status (SES) and oral health behaviors. This was a cross-sectional study that analyzed data from participants in the 2019 National Health Survey (PNS) (n = 88,531). The eligibility criteria were individuals who were 18 years and older and exclusion criterion was living in households located in special or sparsely populated census tracts. Structural equation modeling (SEM) was used to test direct and indirect pathways from a latent variable for SES to oral health through depressive symptoms (assessed through the "Patient Health Questionnaire-9") and use of dental care services. The maximum likelihood estimator for complex samples with the robust standard error was used. The final model presented an adequate fit: RMESA of 0.008, CFI of 0.998, and SMRM of 0.005. The results showed that higher SES was directly associated with better oral health-related behaviors [standardized coefficient (SC): 0.428; p < 0.01] and indirectly through depressive symptoms [(SC): 0.002; p < 0.01] and dental care services [(SC): 0.089; p < 0.01]. The total effect of SES on oral health-related behaviors was equal to [(SC: 0.519 (p < 0.01)]. In conclusion, the findings suggest that high socioeconomic status, mediated by depressive symptoms and dental care services, has a positive effect on oral health.

Toothache and tooth extraction as reasons for dental visits: an analysis of the 2019 National Health Survey.

The aim of this study was to analyze the prevalence of dental visits due to toothache and tooth extraction in Brazil and its association with individual and contextual variables. This two-step cross-sectional study included persons aged 18 years and older in the 2019 National Health Survey who had visited a dentist in the 12 months prior to the interview (n = 40,369). The individual-level outcome was having a dental visit due to toothache or tooth extraction. The ecological-level outcome was the proportion of dental visits for these reasons relative to all dental visits by Brazilian state. Associations with individual - sociodemographic characteristics, number of teeth, and type of health service used - and ecological variables - HDI and dental service coverage - were assessed using Poisson regressions. The prevalence of dental visits due to toothache or extraction was higher among individuals with no formal education, household income < 25% of the minimum wage, of black and brown skin color, living in rural areas, who consulted in the public health system, with 10-19 and 1-9 teeth, and men. The proportion of dental visits due to toothache/extraction in Brazilian states was negatively associated with the HDI and the rate of dental emergency team/100,000 inhabitants and positively associated with primary dental care coverage. The prevalence of dental visits due to toothache/extraction was associated with individual and ecological characteristics, indicating inequities in reasons for dental visits in Brazil. The potential of a well-structured oral health care network to overcome these inequities is suggested and needs to be better explored.

Time series analysis of in-hospital maternal case fatality ratio in the postpartum period according to pregnancy risks and route of delivery in the regions of Brazil, 2010-2019. / Análise temporal da letalidade materna hospitalar no pós-parto segundo risco gestacional e via de parto, nas regiões do Brasil, 2010-2019.

OBJECTIVE: to analyze in-hospital maternal case fatality ratio in the postpartum period according to pregnancy risks and route of delivery, within the Brazilian National Health System, Brazil and macro-regions, 2010-2019. METHODS: this was an ecological time-series study, using data from the Hospital Information System; in-hospital maternal case fatality ratio in the postpartum period took into consideration maternal hospitalizations with outcome 'death' over the total number of hospitalizations per year, according to pregnancy risks and route of delivery, in the regions. RESULTS: there were 19,158,167 hospitalizations for childbirth and 5,110 deaths in the period analyzed; maternal case fatality ratio increased from 1.1 (2010) to 1.9 death/10,000 hospitalizations (2019), in usual-risk pregnancies after vaginal deliveries, and decreased from 10.5 (2010) to 7.0 deaths/10,000 hospitalizations (2019) in high-risk pregnancies after cesarean sections; the Midwest region presented the highest and the South region the lowest case fatality ratio for high-risk pregnancies. CONCLUSION: in-hospital case fatality ratio was higher for high-risk pregnancies, showing differences according to route of delivery and regions.

Increment of Maternal Mortality Among Admissions for Childbirth in Low-risk Pregnant Women in Brazil: Effect of COVID-19 Pandemic? / Aumento da taxa de mortalidade materna entre as admissões para parto em gestantes de baixo risco gestacional no Brasil: Efeito da pandemia do COVID-19?

Abstract Objective To assess the possible impact of the COVID-19 pandemic on maternal mortality among admissions for childbirth in 2020 in relation of the last 10 years. Methods An ecological study with pregnant women who underwent hospital births at the Brazilian unified public health service (SUS, in the Portuguese acronym) in Brazil from 2010 to 2020. The mortality among admissions for childbirth was obtained based on the number of admissions for childbirth with reported death as outcome divided by the total number of admissions. The underlying gestational risk and route of delivery were considered based on the national surveillance system. The average mortality for the period between 2010 and 2019 (baseline) was compared with the rate of deaths in 2020 (1st pandemic year); the rate ratio was interpreted as the risk of death in 2020 in relation to the average of the previous period (RR), with 95% confidence intervals (CIs). Results In 2020, the 1st year of the COVID-19 pandemic, 1,821,775 pregnant women were hospitalized for childbirth and 651 deaths were reported, which represents 8.7% of the total hospitalizations and 11.3% of maternal deaths between 2010 and 2020. There was an increase in maternal mortality after births in 2020 compared with the average for the period between 2010 and 2019, specially in low-risk pregnancies, both in vaginal (RR = 1.60; 95%CI:1.39-1.85) and cesarean births (RR = 1.18; 95%CI:1.04-1.34). Conclusion Maternal mortality among admissions for childbirth according to SUS data increased in 2020 compared with the average between 2010 and 2019, with an increment of 40% in low-risk pregnancies. The increase was of 18% after cesarean section and of 60% after vaginal delivery.

Resumo Objetivo Avaliar os possíveis impactos da pandemia de COVID-19 na mortalidade materna nas admissões para o parto em 2020 em relação ao histórico dos últimos 10 anos. Métodos Estudo ecológico com gestantes que realizaram parto hospitalar pelo Sistema Unificado de Saúde do Brasil (SUS) de 2010 a 2020. Para obter-se a taxa de mortalidade entre as admissões para o parto, foi utilizado o número de internações para parto que tiveram óbito como desfecho dividido pelo total de internações. O risco gestacional e o tipo de parto foram considerados a partir do sistema de vigilância nacional. A média de mortalidade no período de 2010 a 2019 (linha de base) foi comparada com a taxa de mortalidade pós-parto de 2020 (1° ano pandêmico); a razão das taxas foi interpretada como risco de óbito em 2020 em relação à média no período anterior (RR), com intervalo de confiança (IC) de 95%. Resultados Em 2020, 1° ano da pandemia de COVID-19, 1.821.775 gestantes foram internadas para o parto e 651 óbitos foram registrados, o que representa 8,7% do total de internações e 11,3% das mortes maternas entre 2010 e 2020. Houve aumento na mortalidade materna após partos em 2020 em relação à média do período entre 2010 e 2019, especialmente em gestações de baixo risco, tanto em partos normais (RR = 1.60; IC95%: 1.39-185) quanto em cesáreas (RR = 1.18; IC95%: 1.04-1.34). Conclusão A mortalidade entre as admissões para o parto pelo SUS aumentou em 2020 em relação à média de óbitos entre 2010 e 2019, com um incremento de 40% em mulheres de baixo risco gestacional. O aumento verificado foi de 18% após cesárea e de 60% após parto vaginal.

Gestational diabetes mellitus according to different diagnostic criteria: Prevalence and related factors.

OBJECTIVE: Gestational diabetes mellitus (GDM) has an impact on maternal health; however, there is no consensus about the diagnostic criterion and frequency of disease. The objective of this study was to estimate the prevalence of GDM and to evaluate the clinical characteristics of normoglycemic pregnant women and of those diagnosed with gestational diabetes mellitus, based on each criterion. METHODS: Prospective cohort study. Third-trimester pregnant women participated, with the occurrence of GDM being verified, according to two different diagnostic criteria. Prevalence was estimated in each category, and the prevalence ratios (PR) and 95% confidence intervals were adjusted using Poisson Regression. RESULTS: A total of 8.7% of women were diagnosed with GDM (glycemia ≥95) and 8% had glycemic levels ≥92mg/dL according to IADPSG diagnosis. Factors related to the disease were the same, although the magnitude of the associations differed according to the diagnosis criteria. Pre-gestational obesity (PR 3.59 CI 1.28-10,07), previous diseases (PR 3.03 CI 1.15-7.94), and excessive weight gain (PR 4.71 CI 1.80-12.33) were factors related to total GDM, plus low nutritional knowledge (PR 3.17 CI 1.10-9.11). Regardless of the diagnostic criterion, women with GDM were at higher risk of intercurrences during pregnancy. CONCLUSION: Nutritional knowledge and status were associated with GDM occurrence, independently of the diagnosis criteria. The adoption of the glycemic cutoff point of ≥ 92mg/dL indicated an important portion of the population without a diagnosis, suggesting that this cutoff point, more sensitive, should be used in order to guide women and minimize untoward outcomes.

Maternal mortality in South region of Brazil: an analysis from 2000 to 2018.

This study characterises maternal mortality in southern Brazil and verifies its trends between 2000 and 2018. It is an ecological time-series study, analysing secondary data from the Department of Informatics of the Unified Health System. The trend of the maternal mortality ratio (MMR) was calculated using generalised linear regression, and the ratios of the rates according to women's characteristics, with a confidence interval (CI) of 95%. The MMR in the South region went from 53.4 to 36.8 deaths per 100,000 live births from 2000 to 2018, a reduction trend of 1.2 percentage points per year. Mortality was directly related to increasing age (p < .001) and inversely related to schooling (p < .001) and predominated in non-white women (p < .001). The main cause of death was direct causes, including hypertensive disorders. Despite the reduction trend in maternal mortality in southern Brazil, the MMR observed is constantly above the recommended by the World Health Organisation.Impact StatementWhat is already known on this subject? The Maternal Mortality Ratio (MMR) is an indicator that allows an analysis of women's health in relation to the socio-economic and care characteristics of the region where they live. Between 2000 and 2015, Brazil had presented a high MMR, with around 50 deaths per 100,000 live births, while WHO considers a reasonably adequate MMR of fewer than 20 deaths per 100,000 live births.What do the results of this study add? This study updates data about MMR in the Southern Region of Brazil, the one which has the lowest rates in the country, but with variable values between the states. There was a reduction in MMR in southern Brazil between 2000 and 2018 but higher rates for women over 30 years old and in a situation of social vulnerability, as low-income and non-white women. Santa Catarina State presented stable values in the period and remained below the RMM averages of the other states during all years.What are the implications of these findings for clinical practice and/or further research? Comparing previous and current Maternal Mortality Rates in the regional context is important to adapt public health policies for the most affected population. Maternal death is still a reality for single and low-income women, who have greater difficulty in access to health care. Strategies in the Unified Health System are needed to tackle this problem.

Temporal trend and spatial distribution of cases of mother-to-child transmission of HIV in the state of Santa Catarina, Brazil, 2007-2017: an ecological study. / Tendência temporal e distribuição espacial dos casos de transmissão vertical do HIV em Santa Catarina, 2007-2017: um estudo ecológico.

OBJECTIVE: To analyze the temporal trend and spatial distribution of mother-to-child HIV transmission in Santa Catarina between 2007 and 2017. METHODS: This was a mixed ecological study with data from the Notifiable Health Conditions Information System. Linear regression was performed for time series analysis and the mean rates in the period and mean annual percentage changes in the rates of HIV-infected pregnant women were calculated, children exposed to HIV during pregnancy, and seroconversion of children exposed to HIV/AIDS during pregnancy, in addition to data geoprocessing. RESULTS: There were 5,554 records of HIV-infected pregnant women, with a rate of 5.6 pregnant women per 1,000 live births. The mean seroconversion rate was 13.5/100,000 live births (95%CI 6.8;20.1) and it showed a falling trend (APC = -99.4%; 95%CI -99.9;-93.1). The seroconversion rate was more expressive in small towns. CONCLUSION: The rate of HIV-infected pregnant women was stable in the period, whereas the number of children infected with HIV through mother-to-child transmission decreased.
