Systematic review and meta-analysis of breastfeeding and later overweight or obesity expands on previous study for World Health Organization.

AIM: To update a systematic review and meta-analysis of the association of breastfeeding with overweight or obesity that had been commissioned by the World Health Organization. We also assessed the likelihood of residual confounding. METHODS: Two independent reviewers searched MEDLINE, LILACS and Web of Science for manuscripts published between August 2014 and May 2021. Studies that only evaluated infants were excluded. Random-effects models were used to pool the estimates. RESULTS: The review comprised 159 studies with 169 estimates on the association of breastfeeding with overweight or obesity, and most of the studies were carried out among individuals aged 1-9 years (n = 130). Breastfeeding protected against overweight or obesity (pooled odds ratio:0.73, 95% confidence interval:0.71; 0.76). And, even among the 19 studies that were less susceptible to publication bias, residual confounding and misclassification, a benefit was observed (pooled odds ratio:0.85, 95% confidence interval:0.77; 0.93). Among those studies that were clearly susceptible to positive confounding by socioeconomic status, a benefit of breastfeeding was observed even after adjusting for socioeconomic status (pooled odds ratio:0.76, 95% confidence interval: 0.69; 0.83). CONCLUSION: Breastfeeding reduced the odds of overweight or obesity, and this association was unlikely to be due to publication bias and residual confounding.

Influence of maternal pre-pregnancy nutritional status on offspring anthropometric measurements and body composition in three Brazilian Birth Cohorts.

OBJECTIVE: We aimed at evaluating the association of maternal pre-pregnancy nutritional status with offspring anthropometry and body composition. We also evaluated whether these associations were modified by gender, diet and physical activity and mediated by birth weight. DESIGN: Birth cohort study. SETTING: Waist circumference was measured with an inextensible tape, and fat and lean mass were measured using dual-energy X-ray absorptiometry. Multiple linear regression was used to adjust for possible confounders and allele score of BMI. We carried out mediation analysis using G-formula. PARTICIPANTS: In 1982, 1993 and 2004, all maternity hospitals in Pelotas (South Brazil) were visited daily and all live births whose families lived in the urban area of the city were evaluated. These subjects have been followed up at different ages. RESULTS: Offspring of obese mothers had on average higher BMI, waist circumference and fat mass index than those of normal weight mothers, and these differences were higher among daughters. The magnitudes of the association were similar in the cohorts, except for height, where the association pattern was not clear. In the 1982 cohort, further adjustment for a BMI allele score had no material influence on the magnitude of the associations. Mediation analyses showed that birth weight captured part of this association. CONCLUSIONS: Our findings suggest that maternal pre-pregnancy nutritional status is positively associated with offspring BMI and adiposity in offspring. And this association is higher among daughters whose mother was overweight or obese and, birth weight explains part of this association.

OBJECTIVES: To investigate socioeconomic and ethnic group inequalities in prevalence of antibodies against SARS-CoV-2 in the 27 federative units of Brazil. METHODS: In this cross-sectional study, three household surveys were carried out on May 14-21, June 4-7, and June 21-24, 2020 in 133 Brazilian urban areas. Multi-stage sampling was used to select 250 individuals in each city to undergo a rapid antibody test. Subjects answered a questionnaire on household assets, schooling and self-reported skin color/ethnicity using the standard Brazilian classification in five categories: white, black, brown, Asian or indigenous. Principal component analyses of assets was used to classify socioeconomic position into five wealth quintiles. Poisson regression was used for the analyses. RESULTS: 25 025 subjects were tested in the first, 31 165 in the second, and 33 207 in the third wave of the survey, with prevalence of positive results equal to 1.4%, 2.4%, and 2.9% respectively. Individuals in the poorest quintile were 2.16 times (95% confidence interval 1.86; 2.51) more likely to test positive than those in the wealthiest quintile, and those with 12 or more years of schooling had lower prevalence than subjects with less education. Indigenous individuals had 4.71 (3.65; 6.08) times higher prevalence than whites, as did those with black or brown skin color. Adjustment for region of the country reduced the prevalence ratios according to wealth, education and ethnicity, but results remained statistically significant. CONCLUSIONS: The prevalence of antibodies against SARS-CoV-2 in Brazil shows steep class and ethnic gradients, with lowest risks among white, educated and wealthy individuals.

OBJETIVOS: Investigar as desigualdades socioeconômicas e étnicas na prevalência de anticorpos contra SARS-CoV-2 nas 27 unidades federativas do Brasil. MÉTODOS: Neste estudo transversal, três pesquisas domiciliares foram realizadas de 14 a 21 de maio, 4 a 7 de junho, e 21-24 de junho, 2020 em 133 áreas urbanas brasileiras. Amostragem em várias etapas foi utilizada para selecionar 250 indivíduos em cada cidade para se submeter a um teste rápido de anticorpos. Os sujeitos responderam a um questionário sobre bens domésticos, escolaridade e cor da pele/etnicidade (auto-relatada utilizando a classificação padrão brasileira de cinco categorias: branco, preto, pardo, asiático ou indígena). A análise dos componentes principais dos ativos foi utilizada para classificar a posição socioeconómica em cinco quintis de riqueza. A regressão de Poisson foi utilizada para as análises. RESULTADOS: 25 025 indivíduos foram testados na primeira pesquisa, 31 165 na segunda, e 33 207 na terceira, com prevalência de resultados positivos de 1,4%, 2,4% e 2,9%, respectivamente. Indivíduos no quintil mais pobre tinham 2,16 vezes (intervalo de confiança de 95% 1,86; 2,51) mais probabilidade de ter um resultado positivo do que aqueles do quintil mais rico, e aqueles com 12 ou mais anos de escolaridade tinham uma prevalência menor do que aqueles com menos educação. Os indivíduos indígenas tinham 4,71 (3,65; 6,08) vezes mais prevalência do que os brancos, assim como aqueles com cor da pele preta ou parda. O ajuste regional reduziu as taxas de prevalência de acordo com a riqueza, educação e etnia, mas os resultados permaneceram estatisticamente significativos. CONCLUSÕES: A prevalência de anticorpos contra a SARS-CoV-2 no Brasil mostra gradientes relacionados com a posição socioeconómica e a etnia muito acentuados, com os menores riscos entre os indivíduos brancos, educados e ricos.

Validity assessment of a portable anthropometer to measure length in 24-month children from the 2015 Pelotas Birth Cohort.

OBJECTIVE: This study aimed to assess the validity of a portable anthropometer against the gold standard among 2-year-old infants from the 2015 Pelotas (Brazil) Birth Cohort. DESIGN: Birth cohort study. SETTING: A fixed Harpenden® infant anthropometer was considered as the gold standard for measuring infant length due to its greater precision and stability. The portable SANNY® (model ES2000) anthropometer was the instrument to be validated. The acceptable mean difference in length between the anthropometers was 0·5 cm. In order to compare length estimates, the interviewers carried out two length measures for each of the anthropometers (fixed and portable) and for each child. The mean of the two lengths was calculated for each anthropometer, and their difference was calculated. PARTICIPANTS: A subsample of 252 24-month-old members of the 2015 Pelotas (Brazil) birth cohort study. RESULTS: Children's mean age was 23·5 months. According to Bland-Altman plot, there were no differences in overall lengths between the portable and the fixed anthropometers, or in lengths according to sex. There was a high overall concordance between the length estimates of the fixed and portable anthropometers (ρ = 0·94; 95 % CI 0·92, 0·95). CONCLUSIONS: The portable anthropometer proved to be accurate to measure the length of 24-month-old infants, being applicable to studies using the same standardised protocol used in the present study.

Molecular tracking of Salmonella spp. in chicken meat chain: from slaughterhouse reception to end cuts.

Due to the importance of Salmonella spp. in poultry products, this study aimed to track its main contamination routes since slaughtering reception to processing of chicken end cuts. Samples from different steps of slaughtering and processing (n = 277) were collected from two chicken slaughterhouses (Sl1 and Sl2) located in Minas Gerais state, Brazil, and subjected to Salmonella spp. detection. The obtained isolates were subjected to serological identification and tested by PCR for specific Salmonella spp. genes (ompC and sifB). Also, Salmonella spp. isolates were subjected to XbaI macrorestriction and pulsed-field gel electrophoresis (PFGE). Sixty-eight samples were positive for Salmonella spp. and 172 isolates were obtained. Sl1 and Sl2 presented similar frequencies of Salmonella spp. positive samples during reception, slaughtering and processing (p > 0.05), except for higher frequencies in Sl1 for chicken carcasses after de-feathering and evisceration (p < 0.05). PFGE allowed the identification of cross contamination and persistence of Salmonella spp. strains in Sl1. The results highlighted the relevance of the initial steps of chicken slaughtering for Salmonella spp. contamination, and the pre-chilling of carcasses as an important controlling tool. In addition, the presence of Salmonella spp. in chicken end cuts samples represents a public health concern.

Serotypes and Pulsotypes diversity of Listeria monocytogenes in a beef-processing environment.

Utensils and equipment from meat-processing facilities are considered relevant cross-contamination points of Listeria monocytogenes to foods, demanding tracking studies to identify their specific origins, and predict proper control. The present study aimed to detect L. monocytogenes in a beef-processing facility, investigating the diversity of serotypes and pulsotypes in order to identify the possible contamination routes. Surface samples from knives (n=26), tables (n=78), and employees hands (n=74) were collected before and during the procedures from a beef-processing facility, in addition to surface samples of end cuts: round (n=32), loin (n=30), and chuck (n=32). All samples were subjected to L. monocytogenes screening according ISO 11.290-1, and the obtained isolates were subjected to serotyping and pulsed-field gel electrophoresis. Listeria spp. were identified in all processing steps, in 61 samples, and L. monocytogenes was detected in 17 samples, not being found only in knives. Eighty-five isolates were identified as L. monocytogenes, from serotypes 1/2c (n=65), 4b (n=13), and 1/2b (n=7), being grouped in 19 pulsotypes. Considering these results, cross-contamination among hands, tables, and beef cuts could be identified. The obtained data indicated the relevance of cross-contamination in the beef-processing facility, and the occurrence of serotypes 1/2b and 4b in beef cuts distributed for retail sale is a public health concern.

Breastfeeding moderates the association of maternal pre-pregnancy nutritional status with offspring body composition at 30 years.

Maternal pre-pregnancy body mass index is positively associated with offspring obesity, even at adulthood, whereas breastfeeding decreases the risk of obesity. The present study was aimed at assessing whether breastfeeding moderates the association of maternal pre-pregnancy body mass index with offspring body composition at adulthood, using data from 3439 subjects enrolled in a southern Brazilian birth cohort. At 30 years of age, maternal pre-pregnancy body mass index was positively associated with offspring prevalence of obesity, abdominal obesity, as well as body mass index and fat and lean mass index. Breastfeeding moderated the association of maternal pre-pregnancy obesity with offspring adiposity at 30 years of age. For those breastfed<6 months, body mass index was 4.13 kg/m2 (95% confidence interval: 2.98; 5.28) higher among offspring of obese mothers, in relation to offspring of normal weight mothers, whereas among those breastfed≥6 months the magnitude of the difference was small [2.95 kg/m2 (95% confidence interval: 1.17; 4.73)], p-value for interaction = 0.03. Concerning obesity, among those who had been breastfed < 6 months, the prevalence of obesity was 2.56 (95% confidence interval: 1.98; 3.31) times higher among offspring of obese mothers. On the other hand, among those who were breastfed ≥ 6 months, the prevalence of obesity was 1.82 (95% confidence interval: 1.09; 3.04) times higher among offspring of obese mothers. Therefore, among overweight mothers breastfeeding for more than 6 months should be supported, as it may mitigate the consequences of maternal overweight on offspring body composition.

Advanced renal cell carcinoma management: the Latin American Cooperative Oncology Group (LACOG) and the Latin American Renal Cancer Group (LARCG) consensus update.

PURPOSE: Renal cell carcinoma is an aggressive disease with a high mortality rate. Management has drastically changed with the new era of immunotherapy, and novel strategies are being developed; however, identifying systemic treatments is still challenging. This paper presents an update of the expert panel consensus from the Latin American Cooperative Oncology Group and the Latin American Renal Cancer Group on advanced renal cell carcinoma management in Brazil. METHODS: A panel of 34 oncologists and experts in renal cell carcinoma discussed and voted on the best options for managing advanced disease in Brazil, including systemic treatment of early and metastatic renal cell carcinoma as well as nonclear cell tumours. The results were compared with the literature and graded according to the level of evidence. RESULTS: Adjuvant treatments benefit patients with a high risk of recurrence after surgery, and the agents used are pembrolizumab and sunitinib, with a preference for pembrolizumab. Neoadjuvant treatment is exceptional, even in initially unresectable cases. First-line treatment is mainly based on tyrosine kinase inhibitors (TKIs) and immune checkpoint inhibitors (ICIs); the choice of treatment is based on the International Metastatic Database Consortium (IMCD) risk score. Patients at favourable risk receive ICIs in combination with TKIs. Patients classified as intermediate or poor risk receive ICIs, without preference for ICI + ICIs or ICI + TKIs. Data on nonclear cell renal cancer treatment are limited. Active surveillance has a place in treating favourable-risk patients. Either denosumab or zoledronic acid can be used for treating metastatic bone disease. CONCLUSION: Immunotherapy and targeted therapy are the standards of care for advanced disease. The utilization and sequencing of these therapeutic agents hinge upon individual risk scores and responses to previous treatments. This consensus reflects a commitment to informed decision-making, drawn from professional expertise and evidence in the medical literature.

Birth conditions nutritional status in childhood associated with cardiometabolic risk factors at 30 years of age: a cohort study.

This study aimed to assess the association of birth conditions, nutritional status, and childhood growth with cardiometabolic risk factors at 30 years of age. We also evaluated whether body mass index (BMI) at 30 years mediated the association of weight gain in childhood with cardiometabolic risk factors. This is a prospective cohort study that included all live births in 1982 in hospitals in the city of Pelotas, Rio Grande do Sul State, Brazil, whose families lived in the urban area. Mothers were interviewed at birth, and participants were followed at different ages. For our analyses, we used data on weight and height collected at birth, 2 and 4 years and cardiovascular risk factors at 30 years. Multiple linear regressions were performed to obtain adjusted coefficients and G-formula for mediation analysis. Relative weight gain in childhood, despite the age, was positively related to mean arterial pressure, whereas relative weight gain in late childhood was positively associated with carotid intima-media thickness, pulse wave velocity, triglycerides, non-HDL cholesterol, plasma glucose, and C-reactive protein. BMI in adulthood captured the total effect of relative weight gain in the period between 2 and 4 years on carotid intima-media thickness, triglycerides, non-HDL cholesterol, and C-reactive protein. Our findings reinforce the evidence that rapid relative weight gain after 2 years of age may have long-term consequences on the risk of metabolic and cardiovascular disorders.

Effect of Adolescent Body Mass Index Trajectories on Working Memory: A Prospective Birth Cohort in Brazil.

Most research on the association between high body mass index (BMI) and working memory (WM) has been cross-sectional in design, limiting conclusions about long-term effects of overweight and obesity on WM. The aim of this study was to examine the association of BMI trajectory from 11 to 22 years with WM at 22 years of age. Data from the 1993 Pelotas (Brazil) Birth Cohort Study were analyzed (N = 3,010). Information on BMI was collected at ages 11, 15, 18, and 22 years. Group-based trajectory modeling was used separately for each sex to identify BMI trajectories. Working Memory performance (Digit Span backward score) was examined at age 22. Multiple linear regression was used to assess the association between BMI trajectory from 11 to 22 years and WM at age 22. In both sexes, the trajectory groups were: stable normal weight, stable overweight, and stable obesity. In the adjusted analyses, women in the stable-obesity group had lower WM at 22 years (ß = -.49; 95% CI: -0.75, -0.23; p < .001) than those in the stable-normal weight group. No associations were found between BMI trajectories and WM in men. This study may contribute to future investigations of possible explanatory avenues for the association between high BMI and WM.

COVID-19 and outpatient care: a nationwide household survey.

We aimed to assess the proportion of the population in 133 Brazilian municipalities who - from March to August 2020 - had a health problem but failed to seek care or failed to attend to a health service for routine appointment or examination. We conducted a household survey from August 24-27 in 133 Brazilian cities by asking the subjects if, since the beginning of the COVID-19 pandemic in March 2020, they had suffered from a health problem but did not seek care or failed to attend to a routine or screening examination. Poisson regression was used for the analyses. We interviewed 33,250 subjects and 11.8% (95%CI: 11.4-12.1) reported that, since March 2020, they failed to seek care despite being ill, 17.3% (95%CI: 16.9-17.7) failed to attend to a routine or screening examination and 23.9% (95%CI: 23.4-24.4) reported one or both outcomes. Health service closure and fear of the COVID-19 infection were the main reasons for not seeking care. Women and the poorest were more likely to not look for a health service, despite having a health problem or a scheduled routine appointment. On the other hand, those subjects who self-identified as white were less likely to not look for a health service. The COVID-19 pandemic is more critical for the indigenous people and the poorest, and these people are also more likely to not seek care for other health conditions during the pandemic.

Association between maternal prepregnancy body mass index with offspring cardiometabolic risk factors: analysis of three Brazilian birth cohorts.

Evidence suggests that maternal prepregnancy body mass index (BMI) is associated with offspring cardiometabolic risk factors. This study was aimed at assessing the association of maternal prepregnancy BMI with offspring cardiometabolic risk factors in adolescence and adulthood. We also evaluated whether offspring BMI was a mediator in this association. The study included mother-offspring pairs from three Pelotas birth cohorts. Offspring cardiometabolic risk factors were collected in the last follow-up of each cohort [mean age (in years) 30.2, 22.6, 10.9]. Blood pressure was measured using an automatic device, cholesterol by using an enzymatic colorimetric method, and glucose from fingertip blood, using a portable glucose meter. In a pooled analysis of the cohorts, multiple linear regression was used to control for confounding. Mediation analysis was conducted using G-computation formula. In the adjusted model, mean systolic blood pressure of offspring from overweight and obese mothers was on average 1.25 (95% CI: 0.45; 2.05) and 2.13 (95% CI: 0.66; 3.59) mmHg higher than that of offspring from normal-weight mothers; for diastolic blood pressure, the means were 0.80 (95% CI: 0.26; 1.34) and 2.60 (95% CI: 1.62; 3.59) mmHg higher, respectively. Non-HDL cholesterol was positively associated with maternal BMI, whereas blood glucose was not associated. Mediation analyses showed that offspring BMI explained completely the association of maternal prepregnancy BMI with offspring systolic and diastolic blood pressure, and non-HDL cholesterol. Our findings suggest that maternal prepregnancy BMI is positively associated with offspring blood pressure, and blood lipids, and this association is explained by offspring BMI.

Destructive and nondestructive procedures to obtain chicken carcass samples for Escherichia coli and Salmonella spp. detection.

Destructive and nondestructive sampling procedures were compared for Escherichia coli and Salmonella spp. detection in 60 fresh chicken carcasses, which were submitted to the following sampling procedures: rinsing, skin swabbing, tissue excision, and skin excision; the proximity or not to the cloacae region was also considered. The obtained results were compared to identify significant differences (p<0.05). Forty eight chicken carcasses were positive for E. coli, and five were positive for Salmonella spp. For E. coli, nonsignificant differences were observed between rinsing and tissue excision, rinsing and skin excision, and skin excision and tissue excision (p>0.05), thus indicating equivalencies between these techniques. Skin swabbing produced a statistically significant lower frequency of positive results (p<0.05) than all other techniques for E. coli, thus indicating its inadequacy for detection of this microorganism. For Salmonella spp., no significant differences were observed between the sampling techniques (p>0.05), possibly due to the low overall frequency of positive carcasses. No significant differences in the number of positive samples (E. coli or Salmonella spp.) were observed between samples collected near or far from the cloacae region (p>0.05), regardless of the sampling technique. The obtained results demonstrate that the tested sampling techniques were equivalent for Salmonella spp. detection in chicken carcasses, as observed for E. coli with the exception of skin swabbing.

Interest in food and triglyceride concentrations in children and adolescents with autistic spectrum disorder.

OBJECTIVE: To investigate eating behavior and serum concentration of triglycerides in children and adolescents with autistic spectrum disorder. METHODS: Cross-sectional study conducted in the neurodevelopment nucleus, from October 2018 to April 2019 in a neurodevelopment center in the city of Pelotas/RS. Blood samples were collected, and serum was essayed for triglycerides by colorimetric enzymatic reaction. The Children's Eating Behavior Questionnaire was applied to the parents. The comparison between two or three categories of variables was performed with nonparametric tests. Linear regression was used to access the association between the log triglyceride serum concentration and the score above or below the median score of the food response and emotional overeating subscales. RESULTS: Sixty patients were evaluated. The average age was 8.6±3.2 years and most were white (75 %), male (80 %), and overweight (66%). Half of the sample had elevated triglycerides. Triglyceride concentrations were higher among overweight children and adolescents with higher median scores on the "food response" and "emotional overeating" subscales. In the adjusted analysis, the association between triglycerides and higher scores on subscales reflecting interest in food remained significant. CONCLUSION: Children and adolescents with autistic spectrum disorder present high triglyceride concentrations associated with a greater interest in food. Knowledge of this eating behavior may provide more effective nutritional intervention in this population.

Food processing and cardiometabolic risk factors: a systematic review.

OBJECTIVE To systematically review the evidence for the association between food consumption according to processing and cardiometabolic factors in adults and/or the elderly. METHOD Two independent evaluators analyzed the electronic databases PubMed, Web of Science and Lilacs until December 2018. We used the following terms: (convenience foods OR food processing OR highly-processed OR industrialized foods OR minimally-processed OR prepared foods OR processed foods OR ultra-processed OR ultraprocessed OR ultra processed OR unprocessed) AND (metabolic syndrome OR hypertension OR blood pressure OR diabetes mellitus OR glucose OR glycaemia OR insulin OR cholesterol OR triglycerides OR blood lipids OR overweight OR obesity) AND (adult OR adults OR adulthood OR aged OR elderly OR old). We assessed methodological and evidence qualities, and also extracted information for the qualitative synthesis from the selected studies. RESULTS Of the 6,423 studies identified after removing duplicates, eleven met the eligibility criteria. The main food classification we used was Nova. The consumption of ultra-processed foods was positively associated with overweight and obesity, high blood pressure and metabolic syndrome. All articles included met more than 50% of the methodological quality criteria. The quality of evidence was considered moderate for the outcome overweight and obesity and weak for hypertension and metabolic syndrome. CONCLUSIONS The Nova food classification stands out in the area of nutritional epidemiology when assessing the effects of food processing on health outcomes. Although caution is required in the interpretation, the results indicated that the consumption of ultra-processed foods can have an unfavorable impact in the health of individuals.

Food insecurity in a city in the extreme south of Rio Grande do Sul, Brazil, 2016: a population-based study. / Insegurança alimentar em um município do extremo sul do Rio Grande do Sul, 2016: um estudo de base populacional.

OBJECTIVE: to analyze the occurrence of food insecurity and associated factors in Rio Grande, Rio Grande do Sul, Brazil, in 2016. METHODS: this was a cross-sectional population-based study using data obtained by interviewing heads of household; Poisson regression with robust variance adjustment was used. RESULTS: 675 households were included; food insecurity prevalence was 35.2% (95%CI31.6;39.0) and its occurrence was associated with heads of household being female (PR=1.49 - 95%CI1.17;1.90), not being white-skinned (PR=1.49 - 95%CI1.18;1.88), being younger, unmarried (PR=1.39 - 95%CI 1.07;1.81), belonging to the lowest education bracket (PR=1.58; 95%CI 1.17;2,12), belonging to the first and second assets index tertiles, having insufficient money to meet expenses (PR=2.22 - 95%CI 1.76;2.80), being obese (PR=1.39 - 95%CI 1.13;1.71), and being a smoker (PR=1.28 - 95%CI 1.05;1.56). CONCLUSION: food insecurity was associated with all factors studied except alcohol abuse.

Short and long sleep duration and associated factors in pre-adolescence and early adulthood: evidence from the 1993 Pelotas birth cohort study.

OBJECTIVE: The objective of the present study was to investigate the associated factors with short and long sleep duration at ages 11 (pre-adolescence) and 22 years old (early adulthood). METHODS: Participants of the 1993 Pelotas birth cohort with self-reported sleep records at 11 (n = 4442) and 22 (n = 3800) years were included. The total sleep time duration was categorised as short (<9 h for 11 years and <7 h for 22 years), long (>11 for 11 years and >9 for 22 years) and recommended according to the National Sleep Foundation criteria. Multinomial regression analyses were applied according to a hierarchical approach in order to investigate the associated factors with sleep duration patterns. All analyses were stratified by sex. RESULTS: Higher income was associated with higher odds of short sleep duration in 11-year-old boys [OR = 1.54 (CI95%: 1.08; 2.19)] and girls [OR = 1.45 (CI95%: 1.03; 2.06)] and also with lower odds of long sleep duration in both ages. At 22 years, common mental health disorders were associated with higher odds of short sleep duration in both men [OR = 1.56 (CI95%: 1.18; 2.06)] and women [OR = 1.48 (CI95%: 1.11; 1.99)]. Sleep duration was also related to screen time and physical activity showing different association patterns according to sex and age. CONCLUSIONS: Different factors may be associated with sleep duration patterns in pre-adolescence and early adulthood. Our results emphasise the importance of considering stratification analyses to identify associated factors with sleep duration since they may vary according to age and sex.

Birth conditions nutritional status in childhood associated with cardiometabolic risk factors at 30 years of age: a cohort study / Condições de nascimento, estado nutricional na infância e fatores de risco cardiometabólicos aos 30 anos de idade: um estudo de coorte / Condiciones de nacimiento, estado nutricional en la infancia y factores de riesgo cardiometabólico a los 30 años: un estudio de cohortes

Abstract: This study aimed to assess the association of birth conditions, nutritional status, and childhood growth with cardiometabolic risk factors at 30 years of age. We also evaluated whether body mass index (BMI) at 30 years mediated the association of weight gain in childhood with cardiometabolic risk factors. This is a prospective cohort study that included all live births in 1982 in hospitals in the city of Pelotas, Rio Grande do Sul State, Brazil, whose families lived in the urban area. Mothers were interviewed at birth, and participants were followed at different ages. For our analyses, we used data on weight and height collected at birth, 2 and 4 years and cardiovascular risk factors at 30 years. Multiple linear regressions were performed to obtain adjusted coefficients and G-formula for mediation analysis. Relative weight gain in childhood, despite the age, was positively related to mean arterial pressure, whereas relative weight gain in late childhood was positively associated with carotid intima-media thickness, pulse wave velocity, triglycerides, non-HDL cholesterol, plasma glucose, and C-reactive protein. BMI in adulthood captured the total effect of relative weight gain in the period between 2 and 4 years on carotid intima-media thickness, triglycerides, non-HDL cholesterol, and C-reactive protein. Our findings reinforce the evidence that rapid relative weight gain after 2 years of age may have long-term consequences on the risk of metabolic and cardiovascular disorders.

Resumo: O objetivo deste estudo foi avaliar a associação das condições de nascimento, do estado nutricional e do crescimento infantil com fatores de risco cardiometabólicos aos 30 anos de idade. Também foi verificado se o índice de massa corporal (IMC) aos 30 anos mediava a associação entre o ganho de peso na infância e fatores de risco cardiometabólicos. Trata-se de um estudo de coorte prospectivo que incluiu todos os nascidos vivos em 1982 em hospitais da cidade de Pelotas, Rio Grande do Sul, Brasil, residentes da área urbana. As mães foram entrevistadas no parto e os participantes foram acompanhados em diferentes idades. Para as análises, foram utilizados os dados de peso e altura coletados no nascimento e aos 2 e 4 anos de idade e fatores de risco cardiovascular aos 30 anos. Regressões lineares múltiplas foram realizadas para a obtenção de coeficientes ajustados e G-fórmula para a análise de mediação. O ganho de peso relativo na infância, apesar da idade, está positivamente associado à pressão arterial média, enquanto o ganho de peso relativo tardio na infância está positivamente associado à espessura médio-intimal da artéria carótida, à velocidade da onda de pulso, aos triglicerídeos, ao colesterol não-HDL, à glicose plasmática e à proteína C reativa. O IMC na idade adulta capturou o efeito total do ganho de peso relativo entre 2 e 4 anos sobre a espessura médio-intimal da carótida, os triglicerídeos, o colesterol não-HDL e a proteína C reativa. Estes achados reforçam a evidência de que o rápido ganho de peso relativo após os 2 anos de idade pode ter consequências a longo prazo sobre o risco de distúrbios metabólicos e cardiovasculares.

Resumen: El objetivo de este estudio fue evaluar la asociación de las condiciones de nacimiento, estado nutricional y crecimiento infantil con factores de riesgo cardiometabólico a los 30 años de edad. También se verificó si el índice de masa corporal (IMC) a los 30 años mediaba la asociación entre el aumento de peso infantil y los factores de riesgo cardiometabólicos. Se trata de un estudio de cohorte prospectivo que incluyó todos los nacidos vivos en 1982 en hospitales de la ciudad de Pelotas, estado de Río Grande del Sur, Brasil, residentes del área urbana. Las madres fueron entrevistadas en el momento del parto y los participantes fueron seguidos a diferentes edades. Para los análisis, utilizamos los datos de peso y altura recopilados al nacer y a los 2 y 4 años de edad y los factores de riesgo cardiovascular a los 30 años. Se realizaron regresiones lineales múltiples para obtener coeficientes ajustados y la G-fórmula para el análisis de mediación. El aumento de peso relativo en la infancia, a pesar de la edad, se asocia positivamente con la presión arterial media, mientras que el aumento de peso relativo en la infancia tardía se asocia positivamente con el espesor de la íntima-media de la arteria carotídea, la velocidad de la onda del pulso, los triglicéridos, el colesterol no HDL, la glucosa plasmática y la proteína C reactiva. El IMC en adultos capturó el efecto completo del aumento de peso relativo a los 2 y 4 años sobre el espesor de la íntima-media carotídea, los triglicéridos, el colesterol no HDL y la proteína C reactiva. Estos hallazgos refuerzan la evidencia de que el rápido aumento de peso relativo después de los 2 años puede tener consecuencias a largo plazo sobre el riesgo de trastornos metabólicos y cardiovasculares.

Efficacy of doxorubicin after progression on carboplatin and paclitaxel in advanced or recurrent endometrial cancer: a retrospective analysis of patients treated at the Brazilian National Cancer Institute (INCA).

The treatment of endometrial cancer (EC) is challenging. There is no standard of care for patients who progressed after carboplatin and paclitaxel (CT) and all available drugs show a small response and poor long-term survival in this scenario. The objective of this study was to evaluate the efficacy and toxicity profile of palliative doxorubicin after progression to CT therapy in advanced or recurrent EC. A retrospective review of the Brazilian National Cancer Institute database between 2009 and 2013 was performed, and all patients with recurrent and advanced EC treated with palliative doxorubicin after progression on CT were included. Progression-free survival (PFS), overall survival (OS), objective response rates as well as toxicity were evaluated. A total of 33 patients were enrolled, with a median age of 65.7 years. Objective responses were documented in 12.1% (3.0% of complete responses and 9.1% of partial responses). The median PFS was 4.4 months, and the median OS was 8.1 months for patients exposed to doxorubicin. The most common adverse event was anemia observed in 60.6% of patients. This retrospective study suggests that doxorubicin has a modest activity in patients with advanced or recurrent EC after treatment with CT.
