Effects of SARS-CoV-2 infection on health and functional capacity in institutionalized older adults.

OBJECTIVE: To assess the effect of SARS-CoV-2 infection on the health conditions and functional capacity of older adults living in long-term care units in Maceió City - Alagoas State. METHODS: A prospective cohort was conducted with institutionalized older adults of both sexes. Older adults were assessed for clinical conditions (diagnosis of chronic diseases and biochemical tests), functional capacity, and nutritional status. All assessments were repeated on two occasions, maintaining a 6-month interval between them. RESULTS: The sample was composed of 289 older adults. Of the total, 98 (33.9%) were positive for COVID-19 and eight died (2.8%). Men were more likely to have COVID-19 (OR = 3.50; p < 0.01). It was observed that the disease contributed to increasing the frequency of dependent older adults after six months (OR = 1.38; p-interaction < 0.01). It was also observed that after six months of positive diagnosis for COVID-19, there was greater weight loss (p < 0.01), reduced BMI (p < 0.01), increased mean SBP (p = 0.04), and DBP (p = 0.03). CONCLUSION: Effects of COVID-19 in institutionalized older adults go beyond acute complications and compromise blood pressure control, functional capacity, and favor weight loss.

RESUMEN Objetivo: Evaluar el efecto de la infección por SARS-CoV-2 sobre las condiciones de salud y la capacidad funcional de personas mayores que viven en unidades de cuidados a largo plazo en la ciudad de Maceió - Alagoas. Métodos: Se realizó una cohorte prospectiva con ancianos institucionalizados de ambos sexos. Los ancianos fueron evaluados en cuanto a condiciones clínicas (diagnóstico de enfermedades crónicas y pruebas bioquímicas), capacidad funcional y estado nutricional. Todas las evaluaciones se repitieron en dos ocasiones, manteniendo un intervalo de 6 meses entre ellas. Resultados: La muestra estuvo compuesta por 289 personas mayores. Del total, 98 (33,9%) dieron positivo a la COVID-19 y ocho fallecieron (2,8%). Los hombres tenían más probabilidades de tener COVID-19 (OR = 3,50; p <0,01). Se observó que la enfermedad contribuyó al aumento de la frecuencia de ancianos dependientes después de seis meses (OR = 1,38; interacción p < 0,01). Se observó que la enfermedad contribuyó al aumento de la frecuencia de ancianos dependientes después de seis meses (OR = 1,38; interacción p < 0,01). También se observó que después de seis meses de diagnóstico positivo para COVID-19, hubo mayor pérdida de peso (p < 0,01), reducción del IMC (p < 0,01), aumento de la PAS media (p = 0,04) y la PAD (p = 0,03). Conclusión: Los efectos del COVID-19 en ancianos institucionalizados van más allá de las complicaciones agudas y comprometen el control de la presión arterial, la capacidad funcional, favoreciendo la pérdida de peso.

Association between being underweight and excess body weight before SARS coronavirus type 2 infection and clinical outcomes of coronavirus disease 2019: Multicenter study.

OBJECTIVES: The present study aimed to identify associations between extremes in body weight status (underweight and excess body weight) before a COVID-19 diagnosis and clinical outcomes in patients infected with SARS coronavirus type 2. METHODS: A multicenter cohort study was conducted in eight different states in northeastern Brazil. Demographic, clinical (previous diagnosis of comorbidities), and anthropometric (self-reported weight and height) data about individuals who tested positive for COVID-19 were collected. Outcomes included hospitalization, mechanical ventilation, and death. Multivariable logistic regression models, adjusted based on age, sex and previous comorbidities, were used to assess the effects of extremes in body weight status on clinical outcomes. RESULTS: A total of 1308 individuals were assessed (33.6% were elderly individuals). The univariable analyses showed that only hospitalization was more often observed among underweight (3.2% versus 1.2%) and overweight (68.1% versus 63.3%) individuals. In turn, cardiovascular diseases were more often observed in all clinical outcomes (hospitalization: 19.7% versus 4.8%; mechanical ventilation: 19.9% versus 13.5%; death: 21.8% versus 14.1%). Based on the multivariable analysis, body weight status was not associated with risk of hospitalization (underweight: odds ratio [OR]: 1.10; 95% confidence interval [CI] 95%, 0.50-2.41 and excess body weight: OR: 0.81; 95 CI, 0.57-1.14), mechanical ventilation (underweight: OR: 0.92; 95% CI, 0.52-1.62 and excess weight: OR: 0.90; 95% CI, 0.67-1.19), and death (underweight: OR: 0.61; 95% CI, 0.31-1.20 and excess body weight: OR 0.88; 95% CI, 0.63-1.23). CONCLUSIONS: Being underweight and excess body weight were not independently associated with clinical outcomes in patients with COVID-19 in the herein analyzed cohort. This finding indicates that the association between these variables may be confounded by both age and comorbidities.

Absence of breastfeeding on discharge from preterm infants: prevalence and associated factors

INTRODUCTION: Several strategies focused on providing healthcare to premature children have been implemented. Among them, one finds breastfeeding. OBJECTIVE: Investigating the prevalence of, and factors associated with, lack of premature newborn breastfeeding at hospital discharge. METHODS: Cross-sectional study conducted with puerperal women and their preterm newborns in the public health network of Maceió, Brazil. Maternal information was obtained socioeconomic, obstetric, prenatal, and anthropometric data, through questionnaire application, where as information about newborns was collected in their medical records (gestational age at birth, sex, delivery method (vaginal birth or cesarean section), weight, and length at birth, and Apgar scores in the 1st and 5th minute of life), as well as information about the practice of breastfeeding at hospital discharge time. Poisson regression analysis in a hierarchical model was carried out to identify factors associated with the outcome of interest. Results were expressed in Prevalence Ratio (PR) and respective 95% Confidence Intervals (95%CI). RESULTS: 381 dyads were evaluated, 167 (43.8%) of them were not breastfeeding at hospital discharge time. Clinical complications observed in newborns (PR=2.20 95%CI 1.73-2.80), late postpartum contact between mother and child (PR=1.76 95%CI 1.34-2.31), low Apgar in the 1st minute of life (PR=1.44 95%CI 1.15-1.82), and small premature newborn (gestational age at birth <34 weeks) (PR=1.48 95%CI 1.18-1.84) were the factors associated with lack of breastfeeding. CONCLUSION: Lack of premature newborn breastfeeding at hospital discharge time was often observed in the current study and associated with birth-relevant factors.

INTRODUÇÃO: Diversas estratégias têm sido implementadas com enfoque na assistência à saúde da criança prematura, sendo a amamentação umas delas. OBJETIVO: Identificar a prevalência e os fatores associados à ausência de aleitamento materno na alta hospitalar de recém-nascidos prematuros. MÉTODOS: Estudo transversal realizado na rede pública de saúde de Maceió, Brasil com puérperas e seus recém-nascidos pré-termos. Foram obtidas informações maternas sobre dados socioeconômicos, obstétricos, de pré-natal e antropométricos, por meio de questionário, informações dos recém-nascidos via consulta aos prontuários médicos (idade gestacional ao nascer, sexo da criança, via de parto (vaginal ou cesariana), peso e comprimento ao nascimento e índices de Apgar no 1º e 5º minutos de vida) e sobre a prática do aleitamento materno no momento da alta hospitalar. Análise de regressão de Poisson em modelo hierarquizado foi realizada para identificação dos fatores associados ao desfecho de interesse, com os valores expressos em Razão de Prevalência (RP) e respectivos Intervalos de Confiança de 95% (IC95%). RESULTADOS: Foram avaliadas 381 díades, das quais 167 (43,8%) não estavam em aleitamento materno no momento da alta hospitalar. Intercorrências clínicas no recém-nascido (RP=2,20, IC95% 1,73-2,80), contato tardio entre mãe e filho no pós-parto (RP=1,76 IC95% 1,34-2,31), baixo Apgar no 1º minuto (RP=1,44 IC95% 1,15-1,82) e ter idade gestacional ao nascer < 34 semanas (RP=1,48 IC95% 1,18-1,84) foram fatores associados à ausência do aleitamento materno. CONCLUSÃO: A ausência de aleitamento materno na alta hospitalar de recém-nascidos prematuros foi frequente, estando associada a fatores pertinentes ao nascimento.

Serum uric acid levels associated with biochemical parameters linked to preeclampsia severity and to adverse perinatal outcomes.

AIMS: Evaluating the association between serum uric acid levels and biochemical parameters linked to preeclampsia (PE) severity and to adverse perinatal outcomes. METHODS: Cross-sectional study. Information about gestational and biochemical parameters were collected before delivery, whereas perinatal outcomes were observed after it. Pregnant women were divided into hyperuricemia-HU (uric acid ≥ 6 mg/dL) or normouricemia (uric acid, 2.6-5.9 mg/dL) groups. Poisson regression models (prevalence ratio-PR; 95% confidence interval-95% CI), multinomial logistic regression (odds ratio-OR; 95% CI), and Pearson's correlation (correlation coefficient-r) were applied by taking into consideration p < 0.05 as significance level. RESULTS: The total sample comprised 267 pregnant women with PE. HU was observed in 25.8% of patients; it was associated with black pregnant women (p = 0.014) and with primiparity (p = 0.007). Uric acid levels were higher in early PE cases than in late PE cases (p = 0.013); however, there was no significant difference between mild and severe PE cases (p = 0.121). Uric acid recorded a positive correlation to urea (p < 0.001), creatinine (p = 0.002), glutamic-oxaloacetic transaminase (p < 0.001), glutamic-pyruvic transaminase (p = 0.005), ferritin (p = 0.002) and globulin (p = 0.002); as well as negative correlation to platelets (p = 0.035), lactic dehydrogenase (p = 0.039) and albumin (p > 0.001). HU was a factor associated with cesarean delivery (p = 0.030), prematurity (p = 0.001), low birth weight (p < 0.001) and small for gestational age (p = 0.020). CONCLUSION: High serum uric acid levels were associated with early-onset PE. Maternal features were correlated to biochemical parameters linked to PE severity and to adverse perinatal outcomes.

Determinantes sociais e biológicos da mortalidade infantil no Recôncavo da Bahia / Social and biological determinants of child mortality in the Recôncavo of Bahia

Introdução: o Recôncavo é um território de identidade da Bahia propenso a sofrer mais iniquidades sociais, o que pode gerar repercussões negativas nas condições de vida e saúde das crianças e, assim, impactar no Coeficiente de Mortalidade Infantil (CMI). Objetivo: analisar a associação entre os determinantes sociais e biológicos da saúde e a mortalidade infantil nos municípios do Recôncavo da Bahia, no período de 2010 a 2019. Metodologia: estudo ecológico, com dados de Sistemas de Informações em Saúde. Dados de CMI por 1000 nascidos vivos (NV) foram avaliados temporalmente no Recôncavo da Bahia, do ano de 2010 a 2019. Regressão Quantílica foi utilizada para análise do desfecho (CMI) e variáveis de exposição (determinantes). Resultados: o CMI no Recôncavo da Bahia apresentou importantes variações no período avaliado, passando de 9,7/1.000NV em 2010, para 13,1/1.000NV em 2019. Identificou-se associação positiva do CMI com Índice de Gini e uma associação inversa entre o CMI e Índice de Desenvolvimento Humano Municipal (IDHM). Conclusão: no período de 2010 a 2019 houve um aumento de 35% no CMI, no Recôncavo da Bahia. A mortalidade infantil no Recôncavo da Bahia é determinada socialmente pelo Índice de Gini e IDHM. As condições de saúde das crianças podem sofrer consequências em um contexto de aumento da vulnerabilidade social e políticas de subfinanciamento da saúde.

Introduction: the Recôncavo is an identity territory in Bahia that is prone to suffering more social inequities, which can generate negative repercussions on the living conditions and health of children and, thus, impact on the Infant Mortality Rate (IMR). Objective: to analyze the association between the social and biological determinants of health and infant mortality in the municipalities of Recôncavo of Bahia, in the period 2010-2019. Methodology: ecological study, using data from Health Information Systems. IMR data per 1,000 live births (LB) were temporally evaluated in the Recôncavo of Bahia, from 2010 to 2019. Quantile Regression was used for outcome analysis (IMR) and exposure variables (determinants). Results: the IMR in the Recôncavo of Bahia showed important variations in the evaluated period, going from 9.7/1,000LB in 2010, to 13.1/1,000LB in 2019. A positive association was identified between IMR with Gini Index and an inverse association between the IMR and Municipal Human Development Index (MHDI). Conclusion: in the period of 2010-2019 there was an increase of 35.0% in the IMR, in the Recôncavo of Bahia. Infant mortality in the Recôncavo of Bahia is socially determined by the Gini Index and MHDI. Children's health conditions can suffer consequences in a context of increased social vulnerability and underfunded health policies.

Premature birth, low birth weight, small for gestational age and chronic non-communicable diseases in adult life: A systematic review with meta-analysis.

BACKGROUND: Individuals who were born prematurely (PT), with low birth weight (LBW), or small for gestational age (SGA) appear to present a set of permanent changes that make them more susceptible to develop chronic non-communicable diseases (CNCD) in adult life. AIM: Investigating the association between PT birth, LBW or SGA at birth and CNCD incidence in adult life. METHODS: Systematic review with meta-analysis of studies available in three databases - two of them are official (PubMed and Web of Science) and one is gray literature (OpenGrey) - based on pre-established search and eligibility criteria. RESULTS: Sixty-four studies were included in the review, 93.7% of them only investigated one of the exposure variables (46.7% LBW, 35.0% PT and 18.3% SGA at birth), whereas 6.3% investigated more than one exposure variable (50.0% LBW and PT; 50.0% SGA and PT). There was association among all exposure variables in the following outcomes: cardiometabolic (CMD) and glycidic metabolism (GMD) disorders, changes in body composition and risk of developing metabolic syndrome (MS). Female sex was identified as risk factor in the exposure-outcome association. Eighteen (18) articles were included in the meta-analysis. There was positive association between LBW and incidence of CMD (OR: 1.25 [95%CI: 1.11; 1.41]; 07 studies), GMD (OR: 1.70 [95%CI: 1.25; 2.30]; 03 studies) and MS (OR: 1.75 [95%CI: 1.27; 2.40]; 02 studies) in adult life. PT was positively associated with CMD (OR: 1.38 [95%CI: 1.27; 1.51]; 05 studies). CONCLUSIONS: LBW and PT are associated with CMD and GMD development, as well as with the risk of developing MS in adult life.

Associated factors with excessive weight gain in pregnant women from Maceió, Northeastern Brazil.

This article aims to evaluate the associated factors with excessive weight gain in pregnant women from Maceió, the capital of Alagoas, Northeastern Brazil. Cross-sectional study with pregnant women attended in public health in the city of Maceió in 2014, of which socioeconomic, clinical (glycemia, capillary hemoglobin, and blood pressure measurement), dietary, and anthropometric data, including in the latter gestational weight gain, classified as insufficient, adequate and excessive according to the US Institute of Medicine, were collected. The combination of excessive weight gain with the independent variables was tested using the Poisson regression expressed by the Prevalence Ratio (PR) and a 95% confidence interval (CI95%). We studied 403 pregnant women with a mean age of 24.08 ± 6.01 years, with 19.9% of them displayed insufficient weight gain; 14.1% displayed adequate weight gain, and 66.0% displayed excessive weight gain, that was associated with maternal hyperglycemia (PR = 1.35; CI95% = 1.17 to 1.57; p < 0.001). Excessive weight gain is common among pregnant women evaluated with the association of this variable with maternal hyperglycemia.

[Effects of physical exercise on cardiovascular risk and quality of life in hypertensive elderly people]. / Efeitos do exercício físico sobre o risco cardiovascular e qualidade de vida em idosos hipertensos.

The scope of this article is to evaluate the effects of a mixed protocol of physical exercises on cardiovascular risk (CVR), quality of life and the presence of depressive symptoms in elderly hypertensive patients. It involved a longitudinal, prospective and quasi-experimental study with 48 elderly individuals. A physical exercise protocol was developed for 16 weeks according to American College of Sports Medicine, and anthropometric variables (weight, height, body mass index and waist circumference), as well as biochemical variables (total cholesterol, LDL-c, HDL-c; triglycerides) were evaluated. The mean age was 66.5±4.8 years. The frequent CVR factors were dyslipidemia (58.3%) and sedentary lifestyle (45.8%). After intervention, there was a reduction in mean values of total and LDL-cholesterol and increased HDL-cholesterol levels. The CVR and global risk score decreased significantly. The frequency of depressive symptoms decreased from 25% to 4.2%. An improvement was observed in SF-36 physical, health and vitality domains. The mixed protocol of physical exercises constituted a possible low cost and effective alternative in the improvement of the lipid profile and the quality of life related to the health of the elderly who participated in this research.

Estudo longitudinal, prospectivo e quase-experimental com 48 idosos. Desenvolveu-se um protocolo de exercícios físicos durante 16 semanas, segundo American College Sports of Medicine e foram realizadas avaliações antropométricas (peso, estatura, índice de massa corporal e circunferência da cintura) e bioquímicas (colesterol total, LDL-c, HDL-c; triglicerídeos). A média de idade foi de 66,5±4,8 anos. Os fatores de RCV frequentes foram dislipidemia (58,3%) e sedentarismo (45,8%). Após intervenção houve redução dos valores médios de colesterol total e LDL-colesterol e aumentaram níveis de HDL-colesterol. O RCV e a pontuação do escore de risco global diminuíram significativamente. A frequência de sintomas depressivos reduziu de 25% para 4,2%. Observou-se melhora nos domínios do SF-36: físico, saúde e vitalidade. O protocolo misto de exercícios físicos constituiu-se em alternativa possível, de baixo custo e eficaz na melhora do perfil lipídico e da qualidade de vida relacionada à saúde dos idosos desta pesquisa.

Gut microbiota of children with atopic dermatitis: Controlled study in the metropolitan region of São Paulo, Brazil

BACKGROUND: It is possible that imbalances in the composition of the gut microbiota or the relationship of the microbiota with the host may be implicated in the origin of allergy. Therefore, we studied the intestinal microbiota of children with atopic dermatitis (AD). METHODS: Cross-sectional study with 81 children aged 5-11; 23 with AD and 58 controls. Surveys were conducted to obtain demographic, socioeconomic and neonatal data. Diagnosis of AD was made based on the International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire. Eubacteria, Bacteroidetes, Firmicutes, B. fragilis, E. coli, Lactobacillus spp., S. aureus, E. faecalis, Salmonella spp., M. smithii, Bifidobacterium spp., C. difficile and C. perfringens were quantified using real-time PCR. RESULTS: The analysis showed an association between presence of C. difficile (OR: 5.88; 95 % CI: 1.24; 27.98), greater abundance of bifidobacteria (OR: 11.09; 95 % CI: 2.14; 57.39) and a lower abundance of lactobacilli (OR: 0.07; 95 % CI: 0.01; 0.51) in the gut microbiota of children with AD. Counts of Eubacteria (0,05 × 103 and 8.49 × 103), B. fragilis (0.72 × 109 and 4.5 × 109), Lactobacillus spp. (0.02 × 108 and 0.38 × 108), E. coli (0.13 × 109 and 1.52 × 109) and M. smithii (0.02×108 and 0.31 × 108) were lower in children with AD (P < 0.05). CONCLUSIONS: This study confirmed that children living in the metropolitan area of São Paulo (Brazil) with AD have a different microbiota pattern with higher prevalence of C. difficile, lower abundance of Lactobacillus and greater abundance of bifidobacteria, regardless of socioeconomic status

Fatores associados à interrupção precoce do aleitamento materno exclusivo em prematuros / Associated factors with early interruption of exclusive breastfeeding in preterm infants

Objetivo: Avaliar a prevalência e os fatores associados à interrupção precoce do aleitamento materno exclusivo (AME) em recém-nascidos prematuros. Métodos: Coorte prospectiva com puérperas no pós-parto prematuro e seus respectivos filhos, assistidos em hospital da rede pública de saúde, em Maceió-AL, nos anos de 2016/2017. Dados clínicos e obstétricos do binômio, além de informações sobre a prática de aleitamento materno do recém-nascido após alta hospitalar, foram obtidos por aplicação de questionário padronizado. O acompanhamento foi realizado mensalmente, por seis meses. A descontinuidade do aleitamento materno exclusivo, em qualquer momento do estudo, caracterizou a interrupção precoce. O teste de regressão de Poisson foi utilizado para avaliação dos fatores associados ao desfecho, com resultados expressos por Razão de prevalência (RP) e respectivos intervalos de confiança a 95% (IC 95%) considerando p< 0,05 como significativo. Resultados: Dos 132 recém-nascidos que receberam alta hospitalar em aleitamento materno exclusivo e que foram acompanhados até os 6 meses de vida, 94 (71,2%) deles interromperam a amamentação exclusiva precocemente. Idade materna ≥35 anos foi caracterizada como fator de proteção para a interrupção precoce do aleitamento materno exclusivo [RP: 0,591 (0,350-0,997); p= 0,049] e a via de parto cesariana, como fator de risco [RP: 1,284 (1,010-1,633); p=0,041]. Conclusão: Foi alta a prevalência de interrupção do aleitamento materno exclusivo antes dos 6 meses de vida em recém-nascidos prematuros. Foram fatores associados ao desfecho, a idade materna avançada, como fator de proteção, e parto cesáreo, como fator de risco para a interrupção precoce do aleitamento materno.

Objective: To evaluate the prevalence and associated factors with early discontinuation of exclusive breastfeeding (EBF) in preterm infants. Methods: Prospective cohort with puerperal women in the premature postpartum and their respective children, assisted at a public health hospital in Maceió-AL, in 2016/2017. Clinical and obstetric data from the binomial, as well as information about the breastfeeding practice of the newborn after hospital discharge, were obtained by applying a standardized questionnaire. Follow-up was performed monthly for six months. Discontinuity of exclusive breastfeeding at any time of the study characterized early discontinuation. Poisson regression test was used to assess outcome-associated factors, with results expressed as Prevalence Ratio (PR) and 95% confidence ratios (95% CI), considering p <0.05 as significant. Results: Of the 132 newborns who were discharged from exclusive breastfeeding and who were followed up to 6 months of age, 94 (71.2%) of premature infants stopped early exclusive breastfeeding. Maternal age ≥35 years was characterized as a protective factor for early discontinuation of exclusive breastfeeding [PR: 0.591 (0.350-0.997); p = 0.049] and cesarean section as a risk factor [PR: 1.284 (1.010-1.633); p = 0.041]. Conclusion: The prevalence of exclusive breastfeeding interruption before 6 months of life in premature newborns was high. Factors associated with the outcome were advanced maternal age as a protective factor and cesarean delivery as a risk factor for early interruption of breastfeeding.

Counts of Eubacteria (0,05×103 and 8.49×103), B. fragilis (0.72×109 and 4.5×109), Lactobacillus spp. (0.02×108 and 0.38×108), E. coli (0.13×109 and 1.52×109) and M. smithii (0.02×108 and 0.31×108) were lower in children with AD (P<0.05). CONCLUSIONS: This study confirmed that children living in the metropolitan area of São Paulo (Brazil) with AD have a different microbiota pattern with higher prevalence of C. difficile, lower abundance of Lactobacillus and greater abundance of bifidobacteria, regardless of socioeconomic status.

Efeitos do exercício físico sobre o risco cardiovascular e qualidade de vida em idosos hipertensos / Effects of physical exercise on cardiovascular risk and quality of life in hypertensive elderly people

Resumo O objetivo deste artigo é avaliar efeitos de um protocolo misto de exercícios físicos sobre o risco cardiovascular (RCV), qualidade de vida e presença de sintomas depressivos em idosos hipertensos. Estudo longitudinal, prospectivo e quase-experimental com 48 idosos. Desenvolveu-se um protocolo de exercícios físicos durante 16 semanas, segundo American College Sports of Medicine e foram realizadas avaliações antropométricas (peso, estatura, índice de massa corporal e circunferência da cintura) e bioquímicas (colesterol total, LDL-c, HDL-c; triglicerídeos). A média de idade foi de 66,5±4,8 anos. Os fatores de RCV frequentes foram dislipidemia (58,3%) e sedentarismo (45,8%). Após intervenção houve redução dos valores médios de colesterol total e LDL-colesterol e aumentaram níveis de HDL-colesterol. O RCV e a pontuação do escore de risco global diminuíram significativamente. A frequência de sintomas depressivos reduziu de 25% para 4,2%. Observou-se melhora nos domínios do SF-36: físico, saúde e vitalidade. O protocolo misto de exercícios físicos constituiu-se em alternativa possível, de baixo custo e eficaz na melhora do perfil lipídico e da qualidade de vida relacionada à saúde dos idosos desta pesquisa.

Abstract The scope of this article is to evaluate the effects of a mixed protocol of physical exercises on cardiovascular risk (CVR), quality of life and the presence of depressive symptoms in elderly hypertensive patients. It involved a longitudinal, prospective and quasi-experimental study with 48 elderly individuals. A physical exercise protocol was developed for 16 weeks according to American College of Sports Medicine, and anthropometric variables (weight, height, body mass index and waist circumference), as well as biochemical variables (total cholesterol, LDL-c, HDL-c; triglycerides) were evaluated. The mean age was 66.5±4.8 years. The frequent CVR factors were dyslipidemia (58.3%) and sedentary lifestyle (45.8%). After intervention, there was a reduction in mean values of total and LDL-cholesterol and increased HDL-cholesterol levels. The CVR and global risk score decreased significantly. The frequency of depressive symptoms decreased from 25% to 4.2%. An improvement was observed in SF-36 physical, health and vitality domains. The mixed protocol of physical exercises constituted a possible low cost and effective alternative in the improvement of the lipid profile and the quality of life related to the health of the elderly who participated in this research.

Comparison of adequacy of birth weight for gestational age according to different intrauterine growth curves / Comparação da adequação do peso ao nascer para idade gestacional segundo diferentes curvas de crescimento intrauterino

Abstract Objectives: to compare the assessment of the adequacy of birth weight for gestational age according to different intrauterine growth curves. Methods: across-sectional study, which analyzed gestational and neonatal information from 344 mother-newborn binomials. Birth weight data were analyzed using the International Fetal and New Born Growth Consortium for the 21st Century (INTERGROWTH-21st) and compared with the growth curves proposed by Alexander et al. and Fenton & Kim. Newborns were classified as small for gestational age (SGA), suitablefor gestational age (SUGA) or large for gestational age (LGA). Results: among the newborns, 51.2% were male, and 93.0% were born at term. Higher prevalence of SUGA and LGA and lower SGA was found by the INTERGROWTH-21st curves when compared to the references of Fenton & Kim and Alexander et al. Moderate agreement was observed in detecting birth weight by different growth curves. Conclusions: there was a lower detection of SGA infants and a higher screening, especially of LGA infants, in the INTERGROWTH-21st evaluation, when compared to the growth curves of Fenton & Kim and Alexander et al.

Métodos: estudo transversal, onde foram analisadas informações gestacionais e neonatais de 344 binômios mães-recém-nascidos. Os dados de peso ao nascer foram analisados utilizando-se a International Fetal and New Born Growth Consortium for the 21st Century (INTERGROWTH-21st) e comparados com as curvas de crescimento propostas por Alexander et al. e Fenton & Kim. Os recém-nascidos foram classificados em pequenos para idade gestacional (PIG), adequados para idade gestacional (AIG) ou grandes para idade gestacional (GIG). Resultados: dentre os recém-nascidos, 51,2% eram do sexo masculino, sendo que 93,0% nasceram a termo. Maior prevalência de AIG e GIG e menor de PIG foi constatada pelas curvas INTERGROWTH-21st, quando comparadas às referências de Fenton & Kim e Alexander et al. Foi observada concordância moderada na detecção do peso ao nascer pelas diferentes curvas de crescimento. Conclusões: verificou-se menor detecção de recém-nascidos PIG e maior rastreio, principalmente, de recém-nascidos GIG na avaliação pela INTERGROWTH-21st, quando comparada às curvas de crescimento de Fenton & Kim e Alexander et al.

[Factors associated with the lack of breastfeeding upon discharge from hospital in a public maternity facility in Maceió, Alagoas, Brazil]. / Fatores associados à ausência de aleitamento materno na alta hospitalar em uma maternidade pública de Maceió, Alagoas, Brasil.

This article sets out to evaluate the prevalence and associated factors with the lack of breastfeeding upon discharge from hospital in a public maternity facility in Maceio, Alagoas, Brazil. It involved a cross-sectional study performed with women who had recently given birth at the moment of discharge from the maternity ward of a university hospital in the capital. Prevalence ratios (PR) and confidence intervals of 95% (CI95%) were calculated by Poisson regression with the use of a hierarchical model. Approximately 20% of mothers did not breastfeed. Smoking during pregnancy [PR = 5.20; (CI95% =1.75 to 15.33), p = 0.003]; complications during pregnancy [PR =3.50; (CI95% =1.04 to 11.77), p = 0.042] and insufficient information about breastfeeding during prenatal care [PR = 5.44; (CI95% 1.78 to 16.67); p = 0.003] were the major negative factors associated with the lack of breastfeeding. Breastfeeding in the maternity ward was lower than ideal. Guidelines on smoking prevention and encouragement of breastfeeding must be highlighted during prenatal care, especially for women with complications during pregnancy.

O objetivo deste artigo é avaliar a prevalência e os fatores associados à ausência de aleitamento materno na alta hospitalar em uma maternidade pública de Maceió, Alagoas, Brasil. Estudo transversal realizado com puérperas sob alta hospitalar assistidas na maternidade do hospital universitário da capital. Foram calculadas razões de prevalência (RP) e respectivos intervalos de confiança de 95% (IC95%) por regressão de Poisson com emprego de modelo hierarquizado. Aproximadamente 20% das puérperas não estavam amamentando. Hábito tabagista na gravidez [RP = 5,20; (IC95% = 1,75-15,33); p = 0,003]; intercorrências na gestação [RP = 3,50; (IC95% = 1,04-11,77); p = 0,042] e falta de informações sobre aleitamento materno no pré-natal [RP = 5,44; (IC95% = 1,78-16,67); p = 0,003] foram fatores desfavoráveis à amamentação. A prática de aleitamento materno dentro da maternidade está aquém do ideal. Evidencia-se a importância do pré-natal, visando fornecer orientações quanto à prevenção do tabagismo na gestação e aconselhamento sobre aleitamento materno, com atenção especial àquelas puérperas que tiveram intercorrências na gestação.

Fecal microbiota analysis of children with small intestinal bacterial overgrowth among residents of an urban slum in Brazil / Análise da microbiota fecal de crianças com sobrecrescimento bacteriano no intestino delgado de moradoras de uma favela urbana no Brasil

Abstract Objective: To analyze the fecal microbiota composition of children living in an urban slum in Brazil, with or without small intestinal bacterial overgrowth, and to investigate the occurrence of stunting and anemia. Methods: A total of 100 children were studied, aged 5-11 years, from the municipality of Osasco, São Paulo. Small intestinal bacterial overgrowth was screened through hydrogen and methane breath test with lactulose. Weight and height were measured, and the height-for-age and body mass-for-age anthropometric indexes were calculated. The occurrence of anemia was investigated by capillary hemoglobin. Analysis of bacterial phylum, genus, and species was performed by real-time polymerase chain reaction in fecal samples. Results: Small intestinal bacterial overgrowth was identified in 61.0% of the children. A lower mean of height-for-age Z-score ([−0.48 ± 0.90] vs. [−0.11 ± 0.97]; p = 0.027), as well as capillary hemoglobin ([12.61 ± 1.03 g/dL] vs. [13.44 ± 1.19 g/dL]; p < 0.001) was demonstrated in children with SIBO when compared with children without small intestinal bacterial overgrowth. Children with small intestinal bacterial overgrowth presented a higher frequency of Salmonella spp., when compared to those without small intestinal bacterial overgrowth (37.7% vs. 10.3%; p = 0.002). Higher counts of total Eubacteria (p = 0.014) and Firmicutes (p = 0.038) were observed in children without small intestinal bacterial overgrowth; however, a higher count of Salmonella (p = 0.002) was found in children with small intestinal bacterial overgrowth. Conclusion: Children who lived in a slum and were diagnosed with small intestinal bacterial overgrowth showed lower H/A Z-scores and hemoglobin levels. Furthermore, differences were observed in the fecal microbiota of children with small intestinal bacterial overgrowth, when compared to those without it; specifically, a higher frequency and count of Salmonella, and lower counts of Firmicutes and total Eubacteria.

Resumo Objetivo: Analisar a composição da microbiota fecal de crianças moradoras de uma favela urbana no Brasil, com e sem sobrecrescimento bacteriano no intestino delgado, e investigar a ocorrência de déficit de crescimento e anemia. Métodos: Foram estudadas 100 crianças, com idade entre 5 e 11 anos, na cidade de Osasco, São Paulo. Sobrecrescimento bacteriano no intestino delgado foi pesquisado por teste respiratório do hidrogênio e metano no ar expirado com lactulose. Foram mensurados peso, estatura e calculados os índices antropométricos estatura para idade e índice de massa corporal para idade. Foi investigada a ocorrência de anemia, pela avaliação da hemoglobina capilar. A análise dos filos, gêneros e espécies bacterianas em amostras de fezes foi realizada por polymerase chain reaction em tempo real. Resultados: Sobrecrescimento bacteriano no intestino delgado foi diagnosticado em 61,0% das crianças avaliadas. Foi verificada menor média do escore Z do índice estatura para idade (-0,48±0,90 vs.-0,11±0,97 DP) e de hemoglobina capilar (12,61±1,03 vs. 13,44±1,19 g/dL) no grupo de crianças com sobrecrescimento bacteriano no intestino delgado, quando comparadas àquelas sem sobrecrescimento bacteriano no intestino delgado (p < 0,05). Nas crianças com sobrecrescimento bacteriano no intestino delgado foi observada maior frequência de Salmonella spp., quando comparadas àquelas sem sobrecrescimento bacteriano no intestino delgado (37,7% vs. 10,3%; p = 0,002). Maior contagem de Eubactérias totais (p = 0,014) e Firmicutes (p = 0,038) foi observada nas crianças sem sobrecrescimento bacteriano no intestino delgado, enquanto que as crianças com sobrecrescimento bacteriano no intestino delgado apresentaram maior contagem de Salmonella (p = 0,002). Conclusão: Nas crianças com diagnóstico de sobrecrescimento bacteriano no intestino delgado verificaram-se menores valores de estatura para idade e de hemoglobina. Foram constatadas diferenças na microbiota fecal das crianças com sobrecrescimento bacteriano no intestino delgado, especificamente, maior frequência e contagem de Salmonella spp. e menores contagens de Firmicutes e Eubactérias totais.

Prevalence of small for gestational age newborns and associated factors in a Brazilian Northeast capital / Prevalência de recém-nascidos pequenos para a idade gestacional e fatores associados em uma capital do Nordeste brasileiro

Abstract Objectives: to analyze the factors associated with the birth of small for gestational age (SGA)infants, in a Northeastern Brazilian capital. Methods: a cross-sectional study was carried out with 331 pregnant women and their newborns attending the public health network in the city of Maceió, in 2014. Maternal antenatal data were collected (socioeconomic, lifestyle, clinical and nutritional) as well as data of the newborns (gestational age, mode of delivery, sex, birth weight and length), after delivery. Birth weight was classified according to the INTERGROWTH-21st curves, being considered SGA those below the 10th percentile according to gestational age and gender. The results were analyzed by Poisson regression using a hierarchical model and were expressed as prevalence ratios (PR) and their respective 95% confidence intervals (CI95%). Results: it was verified that 5.1% of the newborns were SGA. Regarding the associated factors, after adjustment of the hierarchical model, the variable working outside the home was associated with the endpoint studied [PR = 0.14; (CI95% = 0.02-0.75); p=0.022]. Conclusions: it was verified a low frequency of SGA infants in the evaluated population. The fact that the mother works outside the home proved to be a protective factor for this condition.

Resumo Objetivos: analisar os fatores associados ao nascimento de recém-nascidos pequenos para a idade gestacional (PIG), em uma capital do Nordeste brasileiro. Métodos: estudo transversal realizado com 331 gestantes e seus recém-nascidos atendidos na rede pública de saúde do município de Maceió, em 2014. Foi realizada a coleta de dados maternos antes do parto (socioeconômicos, de estilo de vida, clínicos e nutricionais) e após o parto os dados dos recém-nascidos (idade gestacional no momento do parto, via de parto, sexo, peso e comprimento ao nascer). O peso ao nascer foi classificado segundo as curvas do INTERGROWTH-21st, sendo considerados PIG aqueles abaixo do percentil 10 de acordo com a idade gestacional e o sexo. Os resultados foram analisados por regressão de Poisson, com emprego de modelo hierarquizado, sendo expressos como razões de prevalência [RP] e seus respectivos intervalos de confiança de 95% (IC95%). Resultados: foi constatado que 5,1% dos recém-nascidos eram PIG. Quanto aos fatores associados, após ajuste do modelo hierarquizado, permaneceu-se associada ao desfecho estudado a variável trabalhar fora do lar [RP=0,14; (IC95%=0,02-0,75); p=0,022]. Conclusões: foi verificada baixa frequência de recém-nascidos PIG na população avaliada. O fato da mãe trabalhar fora do lar mostrou-se como fator protetor para esta condição.
