Risk factors for mortality in patients with dengue: A systematic review and meta-analysis.

OBJECTIVE: To investigate risk factors for mortality in dengue. METHODS: We performed a systematic review and meta-analysis searching MEDLINE, Embase, SciELO, LILACS Bireme, and OpenGrey databases to identify eligible observational studies of patients with dengue, of both genders, aged 14 years or older, that analysed risk factors associated with mortality and reported adjusted risk measures with their respective confidence intervals (CIs). We estimated the pooled weighted mean difference and 95% CIs with a DerSimonian and Laird random-effects model. We assessed the methodological quality using the Newcastle-Ottawa Scale. RESULTS: Of 1,170 citations reviewed, 18 papers, with a total of 25,851 patients, were included in the systematic review and 12 in the meta-analysis. Severe hepatitis (OR 29.222, 95% CI 3.876-220.314), dengue shock syndrome (OR 23.575, 95% CI 3.664-151.702), altered mental status (OR 3.76, 95% CI 1.67-8.42), diabetes mellitus (OR 3.698, 95% CI 1.196-11.433), and higher pulse rate (OR 1.039, 95% CI 1.011-1.067) are associated with mortality in patients with dengue. All studies included were classified as having a high quality. CONCLUSIONS: Proper identification and management of these risk factors should be considered to improve patient outcomes and reduce the hidden burden of this neglected tropical disease. Future well-designed studies are needed to investigate the association of other clinical, radiological, and laboratorial findings with mortality in dengue, as well as to develop prognostic models based on the risk factors found in our study.

[Trend in the prevalence of anemia in children from maroon communities according to two population-based surveys in Alagoas State, Brazil (2008-2018)]. / Evolução da prevalência de anemia em crianças quilombolas, segundo dois inquéritos de base populacional em Alagoas, Brasil (2008-2018).

The study aimed to assess trends in the prevalence of anemia in children from quilombos (maroon communities) in Alagoas State, Brazil. This was a descriptive study comparing the results of two household surveys (2008; n = 950 and 2018; n = 426), involving a sample of children from 6 to 59 months of age. Anemia was diagnosed as hemoglobin < 110g/L (HemoCue). Prevalence rates between the two surveys were described by percentage and by prevalence ratio (PR) and 95% confidence interval (95%CI), calculated by Poisson regression. Prevalence rates for anemia in 2008 and 2018 were 53% (95%CI: 49.8-56.1) and 38% (95%CI: 33.4-42.6), respectively, or a decrease of 28.3% (RP = 0.72; 95%CI: 0.63-0.82). Children 6 to 24 months of age had higher anemia rates than those 25 to 59 months of age, both in 2008 (72% vs. 44%) and in 2018 (54.8% vs. 28.3%). There was a reduction in prevalence in both age brackets (23.9% and 35.7%, respectively). This sharper decline in older children meant that younger children had nearly double the prevalence rate compared to older children (PR = 1.94; 95%CI: 1.53-2.46). In conclusion, there was a major decline in prevalence of anemia during the period studied, but anemia persisted as a relevant public health problem, especially in children 6 to 24 months of age. The children in the sample are exposed to harsh social vulnerabilities, evidencing that health promotion for this population requires more than actions in the public health sphere itself. Healthcare workers and administrators should be alert to the data presented here, aimed at implementation of measures to confront the social and health iniquities that contribute to greater vulnerability in this ethnic-racial group.

Objetivou-se avaliar a evolução da prevalência de anemia em crianças quilombolas de Alagoas, Brasil. Trata-se de uma análise descritiva comparando resultados de dois inquéritos domiciliares (2008; n = 950 e 2018; n = 426), envolvendo amostra das crianças de 6 a 59 meses. A anemia foi diagnosticada com hemoglobina < 110g/L (HemoCue). As prevalências entre os dois inquéritos foram descritas percentualmente e pela razão de prevalência (RP) e intervalo de 95% de confiança (IC95%), calculados por regressão de Poisson. As prevalências de anemia em 2008 e 2018 foram, respectivamente, 53% (IC95%: 49,8-56,1) e 38% (IC95%: 33,4-42,6), configurando um declínio de 28,3% (RP = 0,72; IC95%: 0,63-0,82). Crianças de 6 a 24 meses foram mais acometidas do que aquelas de 25 a 59 meses, tanto em 2008 (72% vs. 44%) como em 2018 (54,8% vs. 28,3%). Houve redução de prevalência em ambas as faixas etárias (23,9% e 35,7%, respectivamente). Essa redução mais pronunciada nas crianças mais velhas fez que as mais jovens passassem a ter quase o dobro da prevalência vista nas de maior idade (RP = 1,94; IC95%: 1,53-2,46). Conclui-se que houve declínio expressivo da prevalência de anemia durante o período avaliado, persistindo, porém, como relevante problema de saúde pública, sobretudo entre as crianças de 6 a 24 meses. As crianças avaliadas sobrevivem em grande vulnerabilidade social, evidenciando-se que, para promover a saúde dessa população, não são suficientes ações no âmbito da saúde pública. Gestores e profissionais de saúde devem estar atentos aos dados aqui apresentados, visando à implementação de medidas para enfrentamento das iniquidades sociais e de saúde que contribuem para maior vulnerabilidade desse grupo étnico-racial.

Factors associated with extubation failure in very low birth weight infants: a cohort study in the northeast Brazil.

OBJECTIVES: Identifying and understanding the main risk factors associated with extubation failure of very low birthweight (VLBW) infants in different populations can subsequently help in establishing better criteria while taking decision of extubation. The aim of the study was to identify factors associated with extubation failure in VLBW infants. METHODS: A cohort study of VLBW infants who underwent their first extubation between April 2018 and December 2019 in a Neonatal Intensive Care Unit, Alagoas, Brazil, were included in this study. Extubation failure was defined as reintubation within seven days of extubation. Relative risks of predictive variables different between the extubation success group (ES) and extubation failure group (EF) were estimated with a robust Poisson regression model. RESULTS: Out of the 112 infants included, 26 (23%) cases exhibited extubation failure. Extremely low birth weight (RR 2.55, 95% CI 1.07, 6.06), mechanical ventilation duration for first extubation greater than seven days (RR 2.66, 95% CI 1.10, 6.45), vaginal delivery (RR 2.07, 95% CI 1.03, 4.18) and maternal chorioamnionitis (RR 4.89, 95% CI 1.26-18.98) remained independently associated with extubation failure. EF had a significant greater need for respiratory support, longer oxygen therapy duration, more bronchopulmonary dysplasia (BPD) and longer length of hospital stay, even when adjusted for confounding variables. CONCLUSIONS: Extremely low birth weight infants needing mechanical ventilation, wherein the duration for first extubation was longer than seven days, with vaginal delivery and maternal chorioamnionitis failed more frequently at the first attempt of extubation. And this failure increased the risk of BPD and the length of hospital stay.

Factors associated with childhood anaemia in Afro-descendant communities in Alagoas, Brazil.

OBJECTIVE: To investigate factors associated with anaemia in preschool children. DESIGN: A home survey was conducted in 2018. Anaemia in children (capillary blood Hb level < 110 g/l) was the outcome, and socio-economic, demographic and health factors of the mother and child were the independent variables. The measure of association was the prevalence ratio, and its 95 % CI was calculated using Poisson's regression with robust variance and hierarchical selection of independent variables. SETTING: Afro-descendants communities living in the state of Alagoas, northeast Brazil. PARTICIPANTS: Children aged 6-59 months and their mothers (n 428 pairs). RESULTS: The prevalence of child anaemia was 38·1 % (95 % CI 33·5, 42·7). The associated factors with child anaemia were male sex, age < 24 months, larger number of residents at home (> 4), relatively taller mothers (highest tertile) and higher z-score of BMI for age, after further adjustment for wealth index, vitamin A supplementation in the past 6 months and clinical visit in the last 30 d. CONCLUSIONS: The high prevalence of anaemia observed reveals a relevant public health problem amongst children under five from the quilombola communities of Alagoas. Considering the damage caused to health and multiplicity of risk factors associated with anaemia, the adoption of intersectoral strategies that act on modifiable risk factors and increase vigilance concerning those that are not modifiable becomes urgent.

Spontaneous Breathing Trials in Preterm Infants: Systematic Review and Meta-Analysis.

BACKGROUND: Few data are available on the use of spontaneous breathing trials (SBTs) in the neonatal population, despite advocacy of the practice in many neonatal ICUs. In this meta-analysis, we systematically reviewed the literature regarding the accuracy of SBTs as a predictor for extubation failure in premature infants. METHODS: Following the PRISMA recommendations, scientific articles were collected in December 2019 and January 2020 using PubMed, LILACS, Web of Science, Scopus, Google Scholar, OATD, and BDTD databases. The risk of bias in the studies included herein was assessed using the Quality Assessment of Diagnostic Accuracy Studies-2 tool. The pooled sensitivity and specificity of the studies were estimated using a mixed logistic regression model of 2 levels and a normal bivariate model. RESULTS: Six studies were included for qualitative and quantitative evaluation in this study. All SBTs were performed with endotracheal CPAP, with a total observation time of 3-5 min. The parameters for passing/failing the test were similar in 5 of the 6 studies and included bradycardia or desaturation during the test. The SBT showed a high pooled sensitivity (0.97, 95% CI 0.85-0.99), indicating proper identification of neonates "ready" for successful extubation. However, a low pooled specificity (0.40, 95% CI 0.24-0.58), with many false-positive cases, indicated inaccurate prediction of extubation failure. Heterogeneity of included studies was considerable for sensitivity and substantial for specificity. CONCLUSIONS: The SBT in premature infants can accurately predict extubation success but not extubation failure. Therefore, even though it is an attractive, practical, and easy-to-perform bedside assessment tool, there is a lack of evidence to support its use as an independent predictor of extubation failure in premature infants. Its routine use should be evaluated and monitored carefully.

Effects of vasoconstrictor use on digital nerve block: systematic review with meta-analysis. / Efeitos do uso de vasoconstritores no bloqueio de nervos digitais: revisão sistemática com metanálise.

Conventionally, the association of local anesthetics with vasoconstrictors is avoided at extremities due to the risk of ischemia. However, recent studies suggest that there is safety in the use of vasoconstrictors at extremities. Thus, we sought to evaluate the effectiveness and safety of vasoconstrictor use combined with local anesthetics in digital nerve block compared to the use of anesthetics without vasoconstrictors, through a systematic review with meta-analysis of randomized clinical trials. Until May 2019 we searched MEDLINE, LILACS, SciELO, ScienceDirect, Scopus, ClinicalTrials.gov, and gray literature databases, without date or language restrictions. The keywords were the following: digital block, vasoconstrictor, and ischemia. We included randomized clinical trials in which there was the use of local anesthetics with associated or not with vasoconstrictors in digital blocks. In the primary variables, the occurrence of ischemic complications and the duration of anesthesia were analysed; in the secondary variables, the need for anesthetic reapplication, bleeding control, and latency were observed. Ten studies were included in this review. The occurrence of ischemia was not observed, regardless of the use of vasoconstrictors or not. The use of vasoconstrictors at a concentration of 1:100,000 or less was associated with longer anesthesia duration (P<0.00001), lower need for anesthetic reapplication (P=0.02), lower need for bleeding control (P=0.00006), and lower latency (P<0.00001). We could conclude that the use of vasoconstrictors associated with local anesthetics in digital block proved to be a safe and effective technique.

Convencionalmente, a associação de anestésicos locais com vasoconstritores é evitada em extremidades pelo risco de isquemia. Entretanto, estudos recentes sugerem haver segurança no uso de vasoconstritor em extremidades. Procuramos, assim, avaliar a efetividade e segurança do uso de vasoconstritores combinados com anestésicos locais no bloqueio de nervos digitais em comparação ao uso de anestésicos plenos, através de uma revisão sistemática com metanálise de ensaios clínicos randomizados. Pesquisamos, até maio de 2019, nas bases de dados MEDLINE, LILACS, SciELO, ScienceDirect, Scopus, ClinicalTrials.gov e literatura cinzenta, sem restrições de data ou idioma, os descritores: bloqueio digital, vasoconstritor e isquemia. Foram incluídos ensaios clínicos randomizados nos quais houve a utilização de anestésicos locais associados ou não a vasoconstritores em bloqueios digitais. Nas variáveis primárias foram analisadas a ocorrência de complicações isquêmicas e a duração da anestesia, e nas variáveis secundárias foram observadas necessidade de reaplicação anestésica, de controle de sangramento e latência. Dez estudos foram incluídos nesta revisão. Não foi observada a ocorrência de isquemia, independente do uso ou não de vasoconstritores. O uso de vasoconstritores na concentração de 1:100.000 ou menor esteve associado a maior duração da anestesia (P<0,00001), menor necessidade de reaplicação anestésica (P=0,02), menor necessidade de controle de sangramento (P=0,00006) e menor latência (P<0,00001). Pudemos concluir que uso de vasoconstritores associados a anestésicos locais no bloqueio digital mostrou-se uma técnica segura e efetiva.

Analysis of neonatal mortality risk factors in Brazil: a systematic review and meta-analysis of observational studies / Análise dos fatores de risco na mortalidade neonatal no Brasil: uma revisão sistemática e metanálise de estudos observacionais

Abstract Objective: To identify, using a systematic review and meta-analysis of observational studies, which risk factors are significantly associated with neonatal mortality in Brazil, and to build a comprehensive national analysis on neonatal mortality. Sources: This review included observational studies on neonatal mortality, performed between 2000 and 2018 in Brazilian cities. The MEDLINE, Elsevier, Cochrane, LILACS, SciELO, and OpenGrey databases were used. For the qualitative analysis, the Newcastle-Ottawa Scale was used. For the quantitative analysis, the natural logarithms of the risk measures and their confidence intervals were used, as well as the DerSimonian and Laird method as a random effects model, and the Mantel-Haenszel model for heterogeneity estimation. A confidence level of 95% was considered. Summary of findings: The qualitative analysis resulted in six studies of low and four studies of intermediate-low bias risk. The following exposure factors were significant: absence of partner, maternal age ≥35 years, male gender, multiple gestation, inadequate and absent prenatal care, presence of complications during pregnancy, congenital malformation in the assessed pregnancy, Apgar < 7 at the fifth minute, low and very low birth weight, gestational age ≤ 37 weeks, and caesarean delivery. Conclusion: The most significant risk factors presented in this study are modifiable, allowing aiming at a real reduction in neonatal deaths, which remain high in the country.

Resumo: Objetivo: Identificar, através de uma revisão sistemática e da metanálise de estudos observacionais, quais fatores de risco associam-se significativamente com a mortalidade neonatal no Brasil e construir uma análise nacional abrangente sobre a mortalidade neonatal. Fontes: Foram avaliados os estudos observacionais sobre mortalidade neonatal realizados entre 2000 e 2018 em cidades brasileiras. Usaram-se as bases MEDLINE, Elsevier, Cochrane, LILACS, SciELO e OpenGrey. Para a análise qualitativa, foi usada a Escala Newcastle-Ottawa. Para a análise quantitativa, foram utilizados os logaritmos naturais das medidas de risco e de seus intervalos de confiança, o método de DerSimonian e Laird como modelo de efeitos aleatórios e o modelo de Mantel-Haenszel para estimativa da heterogeneidade. Considerou-se nível de confiança de 95%. Resumo dos achados: A análise qualitativa resultou em seis estudos de baixo e quatro estudos de intermediário-baixo risco de viés. Foram significativos os seguintes fatores de exposição: ausência de companheiro, idade materna ≥ 35 anos, sexo masculino, gestação múltipla, pré-natal inadequado e ausente, presença de intercorrências durante a gestação, de malformação congênita na gestação em estudo, Apgar < 7 no quinto minuto, baixo e muito baixo peso ao nascer, idade gestacional ≤ 37 semanas e parto cesariano. Conclusão: Os fatores de risco mais significativos apresentados neste estudo são modificáveis, o que possibilita almejar uma redução real das mortes neonatais, que ainda permanecem elevadas no país.

Perinatal care in a northeastern brazilian state: structure, work processes, and evaluation of the components of essential newborn care / Cuidado perinatal em um estado do nordeste brasileiro: estrutura, processos de trabalho e avaliação dos componentes do essential newborn care

ABSTRACT Objective: To describe the structure and the processes of care for pregnant women/newborn infants, including the Essential Newborn Care (ENC), in maternity hospitals in Sergipe State, Brazil. Methods: A cross-sectional study carried out between June 2015 and April 2016 in all maternity hospitals of Sergipe with more than 500 deliveries/year (n=11). A questionnaire on the existing structure and work processes was administered to the managers. Subsequently, a representative number of postpartum women from these hospitals were interviewed (n=768). Their medical records, as well as newborn infants' records, were also analyzed. Results: Sergipe has 78 beds of Neonatal Intensive Care Unit (NICU) and 90 beds of Intermediate Care Unit (IMCU) to meet spontaneous and programmed demand. Only six maternity hospitals (54.5%) performed the risk classification, and four (36.3%) had protocols for high-risk parturient care. Regarding the ENC components, only 41% (n=315) of the women had early skin-to-skin contact with their babies, 33.1% (n=254) breastfed in the first hour of life, and 18% (n=138) had a companion always during birth. Conclusions: The distribution of NICU beds between capital city and other cities of the State is adequate, considering Brazilian guidelines. However, there was a low adherence to the protocols for hypertensive and hemorrhagic emergencies, and a low coverage of humanization policies, pregnancy risk classification and ENC practices, especially breastfeeding in the first hour of life, and companion always during birth.

RESUMO Objetivo: Descrever a estrutura e os processos de atendimento a gestante/recém-nascido, incluindo os componentes do Essential Newborn Care (ENC), das maternidades de Sergipe, Brasil. Métodos: Estudo transversal realizado entre junho de 2015 e abril de 2016 em todas as maternidades de Sergipe (n=11) com mais de 500 partos/ano. Foi aplicado um questionário aos gestores sobre a estrutura e os processos de trabalhos existentes. Posteriormente, um número representativo de puérperas desses hospitais foi entrevistado (n=768) e seus prontuários, bem como o dos recém-nascidos, foram analisados. Resultados: Sergipe conta com 78 leitos de Unidade de Terapia Intensiva Neonatal (UTIN) e 90 de Unidade Intermediária (UI) para atendimento da demanda espontânea e programada. Somente seis maternidades (54,5%) realizam a classificação de risco e quatro (36,3%) possuem protocolos para atendimento das parturientes de alto risco. No que se refere aos componentes do ENC, apenas 41% (n=315) das mulheres tiveram contato pele a pele precoce com seu filho, 33,1% (n=254) amamentaram na primeira hora de vida e 18% (n=138) tiveram a presença do acompanhante em todos os momentos do parto. Conclusões: A distribuição de leitos de UTIN entre capital/interior é adequada no Estado, levando-se em consideração a legislação vigente no país. Entretanto, houve baixa adesão aos protocolos das emergências hipertensivas e hemorrágicas, e baixa cobertura das políticas de humanização, da classificação de risco para a gestante e das práticas do ENC, principalmente quanto à amamentação na primeira hora de vida e à presença do acompanhante na parturição.

Regarding the ENC components, only 41% (n=315) of the women had early skin-to-skin contact with their babies, 33.1% (n=254) breastfed in the first hour of life, and 18% (n=138) had a companion always during birth. CONCLUSIONS: The distribution of NICU beds between capital city and other cities of the State is adequate, considering Brazilian guidelines. However, there was a low adherence to the protocols for hypertensive and hemorrhagic emergencies, and a low coverage of humanization policies, pregnancy risk classification and ENC practices, especially breastfeeding in the first hour of life, and companion always during birth.

Efeitos do uso de vasoconstritores no bloqueio de nervos digitais: revisão sistemática com metanálise / Effects of vasoconstrictor use on digital nerve block: systematic review with meta-analysis

RESUMO Convencionalmente, a associação de anestésicos locais com vasoconstritores é evitada em extremidades pelo risco de isquemia. Entretanto, estudos recentes sugerem haver segurança no uso de vasoconstritor em extremidades. Procuramos, assim, avaliar a efetividade e segurança do uso de vasoconstritores combinados com anestésicos locais no bloqueio de nervos digitais em comparação ao uso de anestésicos plenos, através de uma revisão sistemática com metanálise de ensaios clínicos randomizados. Pesquisamos, até maio de 2019, nas bases de dados MEDLINE, LILACS, SciELO, ScienceDirect, Scopus, ClinicalTrials.gov e literatura cinzenta, sem restrições de data ou idioma, os descritores: bloqueio digital, vasoconstritor e isquemia. Foram incluídos ensaios clínicos randomizados nos quais houve a utilização de anestésicos locais associados ou não a vasoconstritores em bloqueios digitais. Nas variáveis primárias foram analisadas a ocorrência de complicações isquêmicas e a duração da anestesia, e nas variáveis secundárias foram observadas necessidade de reaplicação anestésica, de controle de sangramento e latência. Dez estudos foram incluídos nesta revisão. Não foi observada a ocorrência de isquemia, independente do uso ou não de vasoconstritores. O uso de vasoconstritores na concentração de 1:100.000 ou menor esteve associado a maior duração da anestesia (P<0,00001), menor necessidade de reaplicação anestésica (P=0,02), menor necessidade de controle de sangramento (P=0,00006) e menor latência (P<0,00001). Pudemos concluir que uso de vasoconstritores associados a anestésicos locais no bloqueio digital mostrou-se uma técnica segura e efetiva.

ABSTRACT Conventionally, the association of local anesthetics with vasoconstrictors is avoided at extremities due to the risk of ischemia. However, recent studies suggest that there is safety in the use of vasoconstrictors at extremities. Thus, we sought to evaluate the effectiveness and safety of vasoconstrictor use combined with local anesthetics in digital nerve block compared to the use of anesthetics without vasoconstrictors, through a systematic review with meta-analysis of randomized clinical trials. Until May 2019 we searched MEDLINE, LILACS, SciELO, ScienceDirect, Scopus, ClinicalTrials.gov, and gray literature databases, without date or language restrictions. The keywords were the following: digital block, vasoconstrictor, and ischemia. We included randomized clinical trials in which there was the use of local anesthetics with associated or not with vasoconstrictors in digital blocks. In the primary variables, the occurrence of ischemic complications and the duration of anesthesia were analysed; in the secondary variables, the need for anesthetic reapplication, bleeding control, and latency were observed. Ten studies were included in this review. The occurrence of ischemia was not observed, regardless of the use of vasoconstrictors or not. The use of vasoconstrictors at a concentration of 1:100,000 or less was associated with longer anesthesia duration (P<0.00001), lower need for anesthetic reapplication (P=0.02), lower need for bleeding control (P=0.00006), and lower latency (P<0.00001). We could conclude that the use of vasoconstrictors associated with local anesthetics in digital block proved to be a safe and effective technique.

Neonatal near miss determinants at a maternity hospital for high-risk pregnancy in Northeastern Brazil: a prospective study.

BACKGROUND: To investigate the associations of maternal variables - sociodemographic, obstetrical and maternal near miss (MNM) variables - with neonatal near miss (NNM) using the new concept of NNM formulated by the Centro Latino-Americano de Perinatologia (CLAP) and the corresponding health indicators for NNM. METHODS: An analytical prospective cohort study was performed at maternity hospital for high-risk pregnancy in Northeastern Brazil. Puerperal women whose newborn infants met the selection criteria were subjected to interviews involving pretested questionnaires. Statistical analysis was performed with the Epi Info 3.5.1 program using the Chi square test and Fisher's exact test when appropriate, with a level of significance of 5%. A bivariate analysis was performed to evaluate differences between the groups. All the variables evaluated in the bivariate analysis were subsequently included in the multivariate analysis. For stepwise logistic regression analysis, a hierarchical model was plotted to assess variable responses and adverse outcomes associated with MNM and NNM variables. RESULTS: There were 1002 live births (LB) from June 2015 through May 2016, corresponding to 723 newborn infants (72.2%) without any neonatal adverse outcomes, 221 (22%) NNM cases, 44 (4.4%) early neonatal deaths and 14 (1.4%) late neonatal deaths. The incidence of NNM was 220/1000 LB. Following multivariate analysis, the factors that remained significantly associated with increased risk of NNM were fewer than 6 prenatal care visits (odds ratio (OR): 3.57; 95% confidence interval (CI): 2.57-4.94) and fetal malformations (OR: 8.78; 95% CI: 3.69-20.90). Maternal age older than 35 years (OR: 0.43; 95% CI: 0.23-0.83) and previous cesarean section (OR: 0.45; 95% CI: 0.29-0.68) protected against NNM. CONCLUSION: Based on the large differences between the NNM and neonatal mortality rates found in the present study and the fact that NNM seems to be a preventable precursor of neonatal death, we suggest that all cases of NNM should be audited. Inadequate prenatal care and fetal malformations increased the risk of NNM, while older maternal age and a history of a previous cesarean section were protective factors.
