BackgroundPneumonia plays an important role in children’s morbidity and mortality. In Brazil, epidemiological and social changes occurred concomitantly with the universal introduction of the 10-valent pneumococcal conjugate vaccine. This study identified risk factors for pneumonia following the implementation of a pneumococcal vaccination program.MethodsA hospital-based, case-control study involving incident cases of pneumonia in children aged 1–59 months was conducted between October 2010 and September 2013 at a tertiary hospital in northeastern Brazil. The diagnosis of pneumonia was based on the World Health Organization (WHO) criteria. The control group consisted of children admitted to the day-hospital ward for elective surgery. Children with comorbidities were excluded. The risk factors for pneumonia that were investigated were among those classified by the WHO as definite, likely and possible. A multivariate analysis was performed including variables that were significant at p ≤ 0.25 in the bivariate analysis.ResultsThe study evaluated 407 children in the case group and 407 children in the control group. Household crowding (OR = 2.15; 95 % CI, 1,46–3,18) and not having been vaccinated against the influenza virus (OR = 3.59; 95 % CI, 2,62–4.91) were the only factors found to increase the likelihood of pneumonia. Male gender constituted a protective factor (OR = 0.53; 95 % CI, 0,39–0,72).ConclusionChanges on risk factors for pneumonia were most likely associated with the expansion of the vaccination program and social improvements; however, these improvements were insufficient to overcome inequalities, given that household crowding remained a significant risk factor. The protection provided by the influenza vaccine must be evaluated new etiological studies. Furthermore, additional risk factors should be investigated.
Vaccine candidates against COVID-19 have diverse compositions, from traditional inac-tivated virus vaccines to various new-generation vaccines. Currently, approximately 175 research teams worldwide are studying various vaccine possibilities as the necessityto vacci-nate the entire population against the SARS-CoV-2 virus is urgent. Although, the development of a safe and effective COVID-19 vaccine is not easy, the manufacturing, distribution, and administration of the vaccine can also face extraordinary challenges. In this review, we enhance some of the current knowledge regarding the clinical trial phases on different COVID-19 vaccine candidates, its potential strengths and disadvantages, and to discuss ethical aspects and their chances of success in large-scale applications.
ObjectiveTo assess the adequacy of antibiotic prescription in children hospitalized for pneumonia in a reference pediatric hospital in Brazil.MethodsThis was a cross-sectional study involving children aged between 1 month and 5 years who were hospitalized between October 2010 and September 2013. The classification of community-acquired pneumonia (CAP) was based on the clinical and radiological criteria of the World Health Organization (WHO). The analysis of antibiotic adequacy was performed according to the main guidelines on CAP treatment, which include the WHO guidelines, Brazilian Society of Pediatrics guidelines, and international guidelines (Pediatrics Infectious Diseases Society, the Infectious Disease Society of America, British Thoracic Society, and Consenso de la Sociedad latinoamericana de Infectología). A multivariate analysis was performed including variables that have statistical significance of P≤0.25 in the bivariate analysis.ResultsThe majority of the 452 hospitalized children were classified as having severe or very severe CAP (85.18%), and inadequate empiric antimicrobial therapy was started in 26.10% (118/452) of them. Ampicillin was the most used empiric antibiotic therapy (62.17%) for pneumonia, followed by a combination of ampicillin and associated with gentamicin. The initially proposed regimen was modified in 29.6% of the patients, and the most frequent change was the replacement of ampicillin by oxacillin combined with chloramphenicol. The median hospitalization time was 8.5 days, and the lethality rate was 1.55%. There was no statistical difference in adequacy in relation to the severity of pneumonia or degree of malnutrition. In the bivariate analysis, inadequacy of antibiotic therapy regimen was higher in patients undergoing oxygen therapy (P<0.05), which was given to 219 patients (48.45%). Pleural effusion was observed in 118 patients (26.11%) and was associated with higher prescription inadequacy, and it was the only factor that remained in the multivariate analysis (odds ratio =8.89; 95% confidence interval 5.20–15.01).ConclusionAdherence to the main guidelines for antimicrobial therapy according to the childhood CAP was unsatisfactory. Compliance with the guidelines is essential for both the management of pneumonia cases and the decrease in bacterial resistance and it is one of the cornerstone of WHO police of controlling antibiotic resistance.
Concomitant administration of MenC-CRM and 4CMenB in infants was immunogenic, resulting in non-inferior responses against MenC compared to MenC-CRM alone and demonstration of sufficient immune response to MenB, after primary and booster vaccination. Reactogenicity was higher for concomitant vaccines administration, but no safety concerns were identified.
Background Globally, childhood immunization saves the lives of 2–3 million children annually by protecting them against vaccine-preventable diseases. In 2017, 116.2 million children were vaccinated worldwide according to the World Health Organization. Nevertheless, figures suggest that 19.5 million children around the world fail to receive the benefits of complete immunization. Methods This cross-sectional study analyzed vaccine uptake and the factors associated with incomplete vaccination schedule in children of up to 36 months of age assisted by the family health strategy in an irregular settlement located in a state capital city in northeastern Brazil. This study was nested within a larger study entitled “Health, nutrition and healthcare services in an urban slum population in Recife, Pernambuco”, conducted in 2015. A census included 309 children, with vaccination data obtained, exclusively, from their vaccination cards records. An ad hoc database was constructed with variables of interest. Absolute and relative values were calculated for the socioeconomic, demographic, obstetric and biological data. To identify possible factors associated with incomplete vaccination schedule, crude and multivariable Poisson regression analyses were performed, and conducted in accordance with the forward selection method with robust variance and the adjusted prevalence ratio was calculated with the 95% CI. Variables with p -values < 0.20 in the unadjusted stage were included in the multivariable analysis. The statistical significance of each variable was evaluated using the Wald test, with p -values < 0.05. Results Just half of the children (52,1%) was classified as complete vaccination schedule. In the final model, the factors associated with incomplete vaccination schedule were age 12–36 months and the mother who did not complete high school. Conclusion The percentage of vaccine uptake found was far below the recommendation of the National Childhood Immunization Schedule and was associated with child’s age and mother’s education level. Based on these findings, the family healthcare teams may elaborate vaccination strategies aimed at reaching the coverage rates established by the national immunization program. Optimizing coverage will ultimately prevent the resurgence, at epidemic level, of infectious diseases that are already under control in this country.
OBJECTIVE:To verify the adequacy and factors associated with compliance with the immunization schedule (BCG, DTP-Hib, MMR, PCV-10) in children hospitalized with pneumonia at a pediatric referral hospital in Northeast Brazil.METHODS:This is a cross-sectional, descriptive study with an analytical component, with a sample of 452 children hospitalized with pneumonia at the Instituto de Medicina Integral Prof. Fernando Figueira, between 2010 and 2013. The inclusion criterion was children aged from one month to less than five years of age with proof in the immunization record. The exclusion criterion was the presence of hospital-acquired pneumonia or concomitant disease. We have evaluated the adequacy of the immunization schedule for the BCG, tetravalent, MMR, and 10-valent pneumococcal conjugate (PCV-10) vaccines. We used the chi-square test and Fisher's exact test followed by multivariate Poisson regression, estimating the crude and adjusted prevalence ratios and respective 95% confidence intervals. The variables with p < 0.20 in the univariate analysis were included in the multivariate analysis.RESULTS:There was good adequacy in the immunization schedule, except for PCV-10, which presented a percentage lower than 85%. We have observed an association between adequate compliance with the immunization schedule and education level of the mother (89.9% complete high school), sex of the child (87.2% female), age of the child (94.2% younger than six months), and breastfeeding (84.3% breastfed).CONCLUSIONS:Given the high rate of education level of the mother and the high percentage of breastfeeding, we can understand that there is a better understanding of the health of the child by the mothers studied in this study, showing the effectiveness of public policies for infant feeding. However, children did not have good adequacy of the immunization schedule of PCV-10, one of the main vaccines against pneumonia, which can be one of the main factors in the causes of hospitalization, with no influence on the classification of the severity of the disease. In this way, we emphasize that the causes of pneumonia morbidity are not associated with a single factor.
Resumo: Introdução: A residência médica é reconhecida como o “padrão ouro” para a formação de especialistas. O estudo do perfil dos egressos da residência médica é importante para identificar potencialidades e fragilidades da especialização. Objetivo: Este estudo teve como objetivo conhecer o perfil e a satisfação profissional dos egressos dos programas de residência das áreas básicas de um hospital-escola do Nordeste. Método: Trata-se de estudo de corte transversal que utilizou a plataforma eletrônica Survey. Incluíram-se residentes das áreas básicas que concluíram o programa no período de 2013 a 2017. O Termo de Consentimento Livre e Esclarecido foi enviado com o formulário. Realizaram-se análises descritivas das variáveis, e os dados foram apresentados em frequências absoluta e relativa. O trabalho foi aprovado pelo Comitê de Ética do IMIP. Resultados: Dentre os 194 egressos, tivemos a adesão de 79 (40,72%). Com relação aos participantes do estudo: 73,4% eram do gênero feminino e 60,8% já estavam casados. Destacamos que 55,7% informaram que tinham uma renda mensal de dez a 20 salários mínimos. Dos egressos, 54 (68,4%) tinham cursado graduação em instituição de ensino superior privada. Sobre a pós-graduação stricto sensu, 19 egressos (21,7%) tinham mestrado. Sobre a atuação profissional, 93,7% exercem a especialidade e 54 (68,4%) trabalham no estado onde cursaram o programa. Em relação ao serviço público, 64,6% são vinculados ao Sistema Único de Saúde do estado de Pernambuco. Sobre a quantidade de horas de trabalho semanais, 43% trabalham entre 40 e 60 horas. Cerca de 75% dos egressos afirmaram que cursariam o programa novamente na instituição e declararam que a realização da residência facilitou a vida profissional deles. Conclusão: A monitoração periódica de egressos de programa de residência é um instrumento útil para avaliação do programa e permite monitoramento das intervenções implementadas, viabilizando inclusive a obtenção de informações que ajudem no planejamento de novos programas.
