VITAMIN D LEVELS AND LIPID PROFILE IN PATIENTS UNDERGOING BARIATRIC SURGERY.

BACKGROUND: Vitamin, mineral, and metabolic deficiencies occur in the postoperative period of bariatric surgery, in the short and long term, and are worrisome intercurrences. AIMS: To evaluate the association of serum vitamin D levels with the lipid profile in obese patients undergoing bariatric surgery. METHODS: Case series of patients assisted from 2010 to 2018, in a private hospital of medium and high complexity, who underwent bariatric surgery using sleeve gastrectomy or Roux-en-Y gastric bypass techniques, monitored by the same surgeon. Sociodemographic, clinical, laboratory, and anthropometric data were collected preoperatively and at 6, 12, and 24 months after surgery. RESULTS: A total of 156 individuals, mostly female (75.6%) were monitored. The most frequent comorbidities were hepatic steatosis (76.3%) and hypertension (48.27). Regarding preoperative vitamin D levels, only 18.9% of the population had a satisfactory level (≥30 ng/mL). There was a reduction in weight and an improvement in the lipid profile after surgery. Significant correlations were observed between the lipid profile and vitamin D concentration only in the sample submitted to the Roux-en-Y gastric bypass technique: negative correlation between total cholesterol and vitamin D two years after surgery; positive correlation between triglycerides and vitamin D one year after surgery; and negative correlation between high-density lipoprotein and vitamin D two years post-surgery. CONCLUSIONS: It is essential to routinely monitor vitamin D levels and lipid profile pre- and postoperatively in order to avoid damage associated with this vitamin deficiency.

RESUMO RACIONAL: Deficiências vitamínicas, minerais e metabólicas ocorrem no pós-operatório de cirurgia bariátrica, a curto e longo prazo, sendo intercorrências preocupantes. OBJETIVOS: Avaliar a associação dos níveis séricos de vitamina D com o perfil lipídico, em pacientes obesos submetidos à cirurgia bariátrica. MÉTODOS: Série de casos de pacientes atendidos de 2010 até 2018, em hospital privado de média e alta complexidade, submetidos à cirurgia bariátrica pelas técnicas da gastrectomia vertical e derivação gástrica em Y de Roux, acompanhados pelo mesmo cirurgião. Foram coletados dados sociodemográficos, clínicos, dados laboratoriais e antropométricos no pré-operatório, 6 meses, 12 meses e 24 meses após cirurgia. RESULTADOS: Foram acompanhados 156 indivíduos, maioria sexo feminino (75,6%), comorbidades mais frequentes foram esteatose hepática (76,3%) e hipertensão (48,27). Em relação aos níveis de vitamina D pré-operatórios, apenas 18,9% da população apresentaram níveis satisfatórios (=30 ng/mL). Observou-se redução do peso e melhora do perfil lipídico pós-cirúrgico. Sobre as correlações entre o perfil lipídico e concentração de vitamina D foram observadas correlações significativas apenas na amostra que passou pela técnica cirúrgica derivação gástrica em Y de Roux: correlação negativa entre o colesterol total e vitamina D após 2 anos de cirurgia; correlação positiva entre triglicerídeo e vitamina D 1 ano pós-operatório; e correlação negativa entre HDL e vitamina D 2 anos pós-operatório. CONCLUSÕES: é essencial acompanhar os níveis de vitamina D e perfil lipídico no pré e pós-operatório de forma rotineira a fim de evitar danos relacionados a deficiência dessa vitamina.

Birth weight, life course factors and excess weight among schoolchildren in Niterói, Rio de Janeiro, Brazil in 2010

Abstract Objective: To investigate the association between birth weight and excess weight among students aged 6-14 years, adjusted for life course confounding factors. Methods: Cross-sectional study with 6-14-year-old schoolchildren in 2010; 795 school children from two public schools. In addition, a sub-sample was selected using a case-cohort study approach. Sociodemographic, breastfeeding, food introduction, previous weight gain, family history, current clinical and behavioral variables as well as maternal variables related to pregnancy, were collected. Multivariable weighted logistic regression was used to evaluate the association between birth weight and overweight. All prevalent cases of overweight (n = 160) were selected to compose the case group and a random sub-sample of all students participating in the study (n = 276 students, of whom 88 were cases) were the control group. Results: An unadjusted 6% increase in the excess weight prevalence ratio (p-value = 0.004) was found for each 100 g increase in birth weight. With adjustment for age, sex and behavioral variables (models 1 and 2), the association of birth weight with excess weight was positive and statistically significant, but it was no longer significant in the final model (model 3) when clinical variables were considered. Conclusions: Although some of the secondary associations were statistically significant, we could not identify a significant association between birthweight and excess weight in adolescents.

OBJETIVO: O objetivo do presente trabalho foi investigar aingestão dietética e o nível de atividade física como preditores de mudanças no peso e no índice de massa corporal (IMC) de estudantes de uma universidade pública do Nordeste do Brasil. MÉTODOS: Tratou-se de uma coorte, onde 138 estudantes foram avaliados ao início do curso e após 1 ano de vida acadêmica. Foram coletados o peso corporal e a altura, dados sobre o nível de atividade física e sobre o consumo alimentar. O modelo conceitual também considerou variáveis sociodemográficas, comportamentais, de composição corporal e distribuição de gordura corporal. RESULTADOS: A amostra foi 76,1% do sexo feminino, com média de idade de 19,7 ± 3,3 anos no baseline. Ao final do seguimento, 50,7% dos universitários ganharam mais de 0,5Kg de peso, dentre esses, a média de ganho de peso foi 2,87 ± 2,01kg. Nos estudantes que no baseline apresentavam consumo ≤ a uma vez por semana de salada crua e ≤ a uma vez ao dia de frutas e legumes cozidos, a chance de ganho em peso foi de 3,06; 2,57 e 2,49 respectivamente. Houve uma correlação negativa entre a variação anual no peso e a variação no consumo de frutas, salada crua e legumes cozidos. Por outro lado, houve uma correlação positiva com o consumo de embutidos, salgados e doces. Comportamento similar foi observado com a variação no índice de massa corporal (IMC). CONCLUSÃO: Não foi identificado influência da prática de atividade física sobre o ganho de peso. No entanto, o padrão alimentar no baseline e o praticado durante o ano de ingresso na universidade exerceu influência sobre o peso e o IMC dos universitários

OBJETIVO: El objetivo del presente estudio fue investigar la ingesta dietética y el nivel de actividad física como predictores de cambios en el peso y el índice de masa corporal (IMC) de estudiantes de una universidad pública en el noreste de Brasil. MÉTODOS: Se trató de una cohorte, donde se evaluó a 138 estudiantes al inicio del curso y luego de 1 año de vida académica. Se recogieron el peso y la altura corporal, los datos sobre el nivel de actividad física y el consumo de alimentos. El modelo conceptual también consideró variables sociodemográficas, conductuales, de composición corporal y distribución de la grasa corporal. RESULTADOS: La muestra fue 76,1% de mujeres, con una edad media de 19,7 ± 3,3 años al inicio del estudio. Al final del seguimiento, el 50,7% de los estudiantes universitarios ganó más de 0,5 kg de peso, entre ellos, la ganancia de peso promedio fue de 2,87 ± 2,01 kg. En los estudiantes que tenían un consumo inicial ≤ una vez a la semana de ensalada cruda y ≤ una vez al día de frutas y verduras cocidas, la probabilidad de aumento de peso fue de 3,06; 2,57 y 2,49 respectivamente. Hubo una correlación negativa entre la variación anual en peso y la variación en el consumo de frutas, ensalada cruda y verduras cocidas. Por otro lado, hubo una correlación positiva con el consumo de embutidos, snacks y dulces. Se observó un comportamiento similar con la variación en el índice de masa corporal (IMC). CONCLUSIÓN: No se identificó la influencia de la actividad física en el aumento de peso. Sin embargo, el patrón dietético en la línea de base y el practicado durante el año de ingreso a la universidad influyó en el peso y el IMC de los estudiantes

OBJECTIVE: The objective of the present study was to investigate dietary intake and the level of physical activity as predictors of changes in weight and body mass index (BMI) of students at a public university in Northeast Brazil. METHODS: This was a cohort, where 138 students were assessed at the beginning of the course and after 1 year of academic life. Body weight and height, data on the level of physical activity and food consumption were collected. The conceptual model also considered sociodemographic, behavioral, body composition and body fat distribution variables. RESULTS: The sample was 76.1% female, with a mean age of 19.7 ± 3.3 years at baseline. At the end of the follow-up, 50.7% of university students gained more than 0.5 kg of weight, among them, the average weight gain was 2.87 ± 2.01 kg. In students who had a baseline consumption ≤ once a week of raw salad and ≤ once a day of cooked fruits and vegetables, the chance of weight gain was 3.06; 2.57 and 2.49 respectively. There was a negative correlation between the annual variation in weight and the variation in the consumption of fruits, raw salad and cooked vegetables. On the other hand, there was a positive correlation with the consumption of sausages, snacks and sweets. Similar behavior was observed with the variation inbody mass index (BMI). CONCLUSION: The influence of physical activity on weight gain was not identified. However, the dietary pattern in the baseline and that practiced during the year of entry into the university influenced the weight and BMI of the students

Predictive factors of hospitalization in an intensive care unit in patients with COVID-19: A case-control study / Factores predictivos de ingreso a unidad de cuidados intensivos en pacientes con COVID-19: un estudio de casos y controles

OBJECTIVE: The aim of the present study was to evaluate potential predictive factors for the aggravation of COVID-19 in patients hospitalized at a reference hospital in northeastern Brazil. METHODS: A non-paired case-control study was conducted with 235 patients hospitalized at a reference hospital in northeastern Brazil between March and April 2020.The case group was composed of individuals who required hospitalization in the ICU. The control group was composed of patients hospitalized due to COVID-19 who did not meet the criteria established in the institutional protocol for classification as "severe case of the disease" and therefore did not require intensive care. RESULTS: The case group was composed of 84 patients with a median age of 45 years (P25-P75: 36-59); 63.1% weremen; 56.0% were less than 60 years of age; 76.2% had excess weight; 14.3% had a previous heart disease; 46.4% had hypertension; 11.9% had lung disease; and 67.1% took continuous-use medications. The median stay of severe cases in the ICU was positively correlated with weight and BMI only among female patients less than 60 years of age. CONCLUSION: The logistic regression analysis revealed that age older than 60 years and a compromised cardiovascular system were independent predictive factors for the severity of COVID-19

[Validity of information on birth weight for studies based on fetal programming]. / Validade da informação sobre o peso ao nascer para estudos fundamentados na programação fetal.

Birth weight is essential information in fetal programming studies and is generally obtained retrospectively. In Brazil's Information System on Live Births (SINASC), birth weight is valid information but is not always accessible. The study aimed to establish an algorithm for the selection of the most reliable data source for birth weight in the absence of information in the SINASC database. In a cross-sectional study of 6-14-year-old schoolchildren in Niterói, Rio de Janeiro State, Brazil, in 2010, birth weight was collected through a self-completed questionnaire, interview, medical records from the Family Physician Program, and the SINASC database. We calculated intra-class correlation coefficients (ICCs) and differences in mean birth weight. ICCs varied from 0.90 to 0.99. All the other sources showed higher mean birth weight than SINASC, allowing differences up to 100g. Birth weight is recorded at birth (SINASC) or close to it (Family Physician Program), and in the absence of these sources, birth weight as retrieved at 6-14 years of age is a reliable option. To complement information on birth weight in the absence of SINASC, we recommend the following order: Family Physician Program, interview, and questionnaire.

Validade da informação sobre o peso ao nascer para estudos fundamentados na programação fetal / Validity of information on birth weight for studies based on fetal programming / Validez de la información sobre el peso al nacer para estudios basados en la programación fetal

Peso ao nascer é uma informação essencial nos estudos de programação fetal e, em geral, obtida retrospectivamente. No Sistema de Informações sobre Nascidos Vivos (SINASC), peso ao nascer é uma informação válida, mas nem sempre acessível. Objetivou-se estabelecer um algoritmo para seleção da fonte de dados de maior confiabilidade do peso ao nascer na ausência da informação do SINASC. No estudo seccional de estudantes de 6-14 anos, Niterói, Rio de Janeiro, Brasil, 2010, peso ao nascer foi coletado por meio de questionário de autopreenchimento, entrevista, prontuários do Programa Médico de Família (PMF), além do SINASC. Foram calculados coeficientes de correlação intraclasse (CCI) e diferenças das médias de peso ao nascer. CCIs variaram de 0,90 a 0,99. Todas as fontes apresentaram médias de peso ao nascer maiores do que SINASC, considerando-se aceitáveis diferenças até 100g. O peso ao nascer é registrado no nascimento (SINASC) ou próximo deste (PMF) e, na ausência dessas fontes, a lembrança do peso ao nascer de 6-14 anos após o nascimento é uma opção confiável. Para complementar a informação sobre peso ao nascer na ausência do SINASC, recomenda-se a seguinte ordenação: PMF, entrevista e questionário.

[The evolution of maternal and child healthcare and birth weight in the State of Pernambuco in 1997 and 2006]. / Evolução da assistência materno-infantil e do peso ao nascer no Estado de Pernambuco em 1997 e 2006.

The scope of this paper was to assess the evolution and influence of maternal and child care on birth weight variation in the state of Pernambuco. The study used data from two cross-sectional population-based household surveys conducted with under-five children in the state of Pernambuco in 1997 (n = 1906) and 2006 (n = 1555). The sample was calculated to ensure the representativeness of two geo-economic strata: urban and rural areas. The variables studied were prenatal, delivery care and birth weight. The x(2) test was used to compare the categorical variables and mean difference in birth weight was calculated between the years studied with the respective 95% confidence interval. A marked improvement was seen in prenatal care and an increase in the frequency of caesarean section. In the rural area there was a significant 112 g decrease in mean birth weight. In 2006, access to at least one prenatal care appointment occurred irrespective of maternal schooling, however, in 1997 and 2006 access to adequate prenatal care was higher among mothers with better schooling. In spite of the improvement in prenatal and delivery care, poor access, excess of medical interventions and the increase in newborn survival may be influencing the variations in mean birth weight in the State of Pernambuco.

Evolução da assistência materno-infantil e do peso ao nascer no Estado de Pernambuco em 1997 e 2006 / The evolution of maternal and child healthcare and birth weight in the State of Pernambuco in 1997 and 2006

Avaliar a evolução e a influência da assistência materno-infantil na variação do peso ao nascer no estado de Pernambuco. Os dados analisados provêm de duas pesquisas transversais da população de crianças menores de cinco anos, estudadas por inquéritos domiciliares em 1997 (n = 1906) e 2006 (n = 1555). A amostra foi calculada para assegurar a representatividade de dois estratos geoeconômicos: setores urbano e rural. Estudou-se a assistência ao pré-natal e parto e o peso ao nascer. Utilizou-se o teste do qui-quadrado para comparar as variáveis categóricas e calculou-se a diferença da média de peso ao nascer nos anos pesquisados, e os respectivos intervalos de confiança de 95%. Verificou-se importante melhora na assistência ao pré-natal e aumento do parto cesáreo. Houve uma redução significante de 112g na diferença da média de peso ao nascer no meio rural. Em 2006 o acesso a pelo menos 1 consulta de pré-natal ocorreu independente da escolaridade materna, no entanto, o acesso ao pré-natal mais adequado foi maior entre as mães de maior escolaridade, tanto em 1997, como em 2006. Apesar da expansão da assistência no pré-natal e no parto, o acesso iníquo, o excesso de intervenções médicas e o aumento da sobrevida de recém nascidos podem estar contribuindo para as variações da média de peso ao nascer no estado de Pernambuco.

Análise da sobrevida infantil segundo características maternas, da gestação, do parto e do recém nascido na coorte de nascimento de 2005 no Município do Rio de Janeiro-RJ, Brasil / Infant survival analysis according to maternal, pregnancy, parturition and newborn characteristics in the live birth cohort of 2005 in the Municipality of Rio de Janeiro-RJ, Brazil

BJETIVO: investigar associações entre sobrevida infantil e características maternas, da gestação, do parto e do recém-nascido na coorte de nascimento de 2005, no município do Rio de Janeiro, estado do Rio de Janeiro, Brasil. MÉTODOS: estudo de coorte retrospectivo com dados dos Sistemas de Informações sobre Nascidos Vivos (Sinasc) e sobre Mortalidade (SIM); calculou-se a probabilidade de sobrevida infantil pelos métodos de tábua de vida atuarial e de Kaplan-Meier. RESULTADOS: probabilidade de sobrevida estimada em 0,9861; maiores probabilidades de morte encontradas entre nascidos vivos de mães com menos de 20 anos de idade (0,0148), por parto vaginal (0,0146), do sexo masculino (0,0154), com peso ao nascer inferior a 2.500g (0,0861) e prematuros (0,0992) ; a promoção de cuidados perinatais pelos serviços de saúde poderia evitar cerca de 65,0 por cento desses óbitos. CONCLUSÃO: o uso dos dados dos sistemas nacionais de informações é um importante instrumento de definição de políticas de saúde materno-infantil.

OBJECTIVE: to investigate associations between infant survival and maternal, pregnancy, parturition and newborn characteristics, in the birth cohort of 2005, in the municipality of Rio de Janeiro, state of Rio de Janeiro, Brazil. METHODS: a retrospective cohort study, carried out using data from Live Birth Information System (Sinasc) and Mortality Information System (SIM); probability of infant survival was estimated using tactuarial life table and Kaplan-Meier methods. RESULTS: the probability of infant survival was estimated in 0.9861; highest probabilities of death were found among babies born to mothers aged under 20years (0.0148), by vaginal delivery (0.0146), male (0.0154), weighing under 2,500g (0.0861) and premature (0.0992); about 65.0 per cent of these deaths could be avoided improving perinatal care health services. CONCLUSION: the use of National information systems data is an important tool to define maternal and child policies.
