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.

Is catechol-O-methyltransferase gene associated with temporomandibular disorders? A systematic review and meta-analysis.

BACKGROUND: Temporomandibular disorder (TMD) is a condition, in which multiple factors act synergistically to determine the outcome of the disorder. AIM: A systematic review and meta-analysis was conducted to evaluate the association between genetic polymorphisms in catechol-O-methyltransferase (COMT) and TMD. DESIGN: Observational studies that investigated this association were included. The risk of bias and study quality were evaluated according to the Newcastle-Ottawa tool. The meta-analysis was performed for each polymorphism associated with TMD signs and symptoms. RESULTS: A total of 1903 articles were identified. Ten remained in the qualitative analysis: six were classified as low risk of bias and four with moderate risk of bias, and three were included in the meta-analysis. The polymorphism rs6269, in the genotypic model (0.65; CI = 0.44-0.97; P = .04) and in the allelic model (0.73; CI = 0.54-0.98; P = .04), was associated with myofascial pain. The rs9332377 was associated with myofascial pain in the genotypic model (2.69; CI = 1.51-4.76; P = .0007) and in the allelic model (1.46; CI = 1.01-2.13; P = .05) and with painful TMD in the genotypic model (2.08; CI = 1.27-3.40; P = .004) and in the allelic model (1.34 CI = 0.98-1.82; P = .06). CONCLUSION: The polymorphisms in COMT were significantly associated with TMD.

Polymorphisms in COL2A1 gene in Adolescents with Temporomandibular Disorders.

OBJECTIVES: Temporomandibular disorder (TMD) is considered a functional disorder with multifactorial aspects. The goal of this study was to investigate if genetic polymorphisms in the COL2A1 gene could be associated with TMD in adolescents. STUDY DESIGN: The case group (TMD-affected) included individuals diagnosed with any of the following TMD subgroups according to the RDC/TMD criteria: myofascial pain, disc displacements and arthralgia. Genomic DNA for molecular analysis was extracted from buccal cells and genetic polymorphisms in COL2A1 were genotyped by real time polymerase chain reactions using the TaqMan assay. Data were analyzed using the Epi Info 3.5.7 and Stata software. RESULTS: 249 subjects were included in this study (148 subjects "affected" by TMD). There were no significant differences between the affected and unaffected individual (p>0.05), for TMD, arthralgia and myofascial pain however, rs2276454 was borderline in the genotype distribution (p=0.07) and was associated with disc displacement (p=0.03) in the allelic distribution. Recessive model showed significant differences between groups for with disc displacement (p=0.02). CONCLUSIONS: Genetic polymorphisms in COL2A1 are not associated with myofascial pain, arthralgia or TMD in adolescents but this study provides evidence that rs2276454 is involved in the disc displacement of the temporomandibular joint.

Increment of Maternal Mortality Among Admissions for Childbirth in Low-risk Pregnant Women in Brazil: Effect of COVID-19 Pandemic?

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.

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.

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%: 1.39­185) quanto em cesáreas (RR = 1.18; IC95%: 1.04­1.34). 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.
