RESUMEN

PURPOSE: This study aimed to identify continuous epileptiform discharges (CEDs) on electroencephalograms (EEG) and to determine their clinical significance in children with congenital Zika syndrome (CZS). METHODS: This prospective cohort study included 75 children diagnosed with CZS born from March 2015 and followed up until September 2018 (age up to 36 months). EEG was performed to detect CEDs up to 24 months old. Data on obstetric, demographic, and clinical signs; cranial computed tomography (CT); ophthalmology examination; anti-seizure medication; growth; and motor development were collected. Fisher's exact test was used to verify the associations between categorical variables, and the T- test was used to compare the mean z-scores of anthropometric measurements between the groups with and without CED. RESULTS: CEDs were identified in 41 (54.67 %) children. The mean age of CEDs identification was 12.24 ± 6.86 months. Bilateral CEDs were shown in 62.89 % of EEGs. CEDs were associated with severe congenital microcephaly, defined by z-score >3 standard deviation of head circumference (HC) below the mean for sex and age (p = 0.025), and worse outcomes, including first seizure before 6 months (p = 0.004), drug-resistant epilepsy (p < 0.001), chorioretinal scarring or mottling (p = 0.002), and severe CT findings (p = 0.002). The CED group had lower mean z-scores of HC up to 24 months of age. CONCLUSION: This is the first description of the prevalence and significance of CEDs that also remains during wakefulness in patients with CZS. New investigations may suggest that it is more appropriate to classify the EEG not as a CED, but as a periodic pattern. Anyway, CEDs may be a marker of neurological severity in children with CSZ.

RESUMEN

OBJECTIVE: To evaluate the direct, indirect, and total prospective effects of serum concentrations of [25(OH)D, 25-hydroxycolecalciferol] on depressive symptoms in older adults. METHODS: Data from the second (2013-2015) and third (2017-2019) waves of the EpiFloripa Aging Cohort Study (≥ 60 years) were analyzed. Depressive symptoms were assessed by the 15-item Geriatric Depression Scale (GDS-15). 25(OH)D levels were measured using the microparticle chemiluminescence method. A directed acyclic graph (DAG) was constructed to identify the minimum set of adjustments. Structural equation modeling (SEM) analysis was used to determine the effects of 25(OH)D on depressive symptoms. RESULTS: A total of 574 older adults' data were analyzed (63.1% female). In the follow-up (n=390), 16.2% of older adults presented high-severity of depressive symptoms (> or = 6 points). SEM analysis revealed a small direct and negative effect of 25(OH)D (ß=-0.11, P < 0.05), and a total negative effect (ß=-0.13; P < 0.05) on depressive symptoms on wave 3 (an increase of 25(OH)D led to a decrease on depressive symptoms). No direct effect on wave 2 and no indirect effect mediated by depressive symptoms in wave 2 were found. CONCLUSIONS: Findings indicate a prospective association between 25(OH)D and depressive symptoms, suggesting a long-term effect in older adults from southern Brazil.

RESUMEN

BACKGROUND: Dental eruption is part of a set of children´s somatic growth phenomena. The worldwide accepted human dental eruption chronology is still based on a small sample of European children. However, evidence points to some population variations with the eruption at least two months later in low-income countries, and local standards may be useful. So, this study aimed to predict deciduous teeth eruption from 12 months of age in a Brazilian infant population. METHODS: We developed a cross-sectional study nested in four prospective cohorts - the Brazilian Ribeirão Preto and São Luís Cohort Study (BRISA) - in a sample of 3,733 children aged 12 to 36 months old, corrected by gestational age. We made a reference curve with the number of teeth erupted by age using the Generalized Additive Models for location, scale, and shape (GAMLSS) technique. The explanatory variable was the corrected children´s age. The dependent variable was the number of erupted teeth, by gender, evaluated according to some different outcome distributional forms. The generalized Akaike information criterion (GAIC) and the model residuals were used as the model selection criterion. RESULTS: The Box-Cox Power Exponential method was the GAMLSS model with better-fit indexes. Our estimation curve was able to predict the number of erupted deciduous teeth by age, similar to the real values, in addition to describing the evolution of children's development, with comparative patterns. There was no difference in the mean number of erupted teeth between the sexes. According to the reference curve, at 12 months old, 25% of children had four erupted teeth or less, while 75% had seven or fewer and 95% had 11 or fewer. At 24 months old, 5% had less than 12, and 75% had 18 or more. At 36 months old, around 50% of the population had deciduous dentition completed (20 teeth). CONCLUSION: The adjusted age was an important predictor of the number of erupted deciduous teeth. This outcome can be a variable incorporated into children's growth and development curves, such as weight and height curves for age to help dentists and physicians in the monitoring the children's health.

RESUMEN

Purpose: We assessed whether anticipated stigma (i.e., fear of public mistreatment due to gender identity) impacts communication between transgender women (TGW) living with HIV and health care providers. Methods: This is a secondary analysis of baseline data from Trans Amigas, a study conducted in Brazil, 2018. The study population consisted of TGW living with HIV, older than 18 years, residing in the São Paulo metropolitan area. We used multivariable logistic regression (α = 0.05), mediation, and bootstrapping for the analysis. Results: One hundred and thirteen participants completed the study. Fear of public mistreatment had an adjusted odds ratio (aOR) of 7.42 (p = 0.003) for difficulty reporting new symptoms to providers. Concerning fear of public mistreatment, we found that unemployment had an aOR of 3.62 (p = 0.036); sex work, an aOR of 2.95 (p = 0.041); and issues related to name change in documents, an aOR of 2.71 (p = 0.033). For the indirect effect on difficulty reporting new symptoms, mediated by fear of public mistreatment, unemployment had an aOR of 1.52 (confidence interval [CI] = 0.88-2.24); sex work, an aOR of 1.48 (CI = 0.81-2.52); and name change issues, an aOR of 1.47 (CI = 0.96-2.43). Conclusions: Anticipated stigma was associated with communication difficulties between TGW living with HIV and providers. Our data suggest that structural factors associated with anticipated stigma could indirectly impact on difficulty reporting new symptoms. These findings indicate the importance of considering social contexts that intersect with individual experiences when analyzing communication barriers between providers and patients, and the need to strengthen social policies for TGW in Brazil. Clinical Trial Registration number: R34MH112177.

RESUMEN

This study aimed to identify the dietary patterns (DPs) of adolescents and assess indicators of subclinical inflammation. It was a cross-sectional study aligned with the RPS cohort with data from São Luís, Maranhão, Brazil. We evaluated 511 adolescents between 18-19 years old. DPs were identified with a factor analysis of the principal components. Nutritional status was assessed with body mass index and body fat percentages. Hierarchical modeling was performed using a linear regression to estimate the beta coefficient (ß) of the independent variables with the dependent variables interleukin-6 and high-sensitivity C-reactive protein (hs-CRP). Five DPs were identified: energy-dense, sugar-sweetened beverages and breakfast cereals, prudent, traditional Brazilian and alcoholic and energy beverages. Greater adherence to the prudent DP was associated with a lower concentration of interleukin-6 (ß = -0.11; p value = 0.040). Greater adherence to the DP "traditional Brazilian" and "alcoholic and energy beverages" were associated with increased IL-6, mediated by the nutritional status. A higher BMI (ß = 0.36; p value = <0.001) and %BF (ß = 0.02; p value = 0.014) were associated with higher hs-CRP concentrations. The nutritional status and "prudent" pattern were associated with inflammatory biomarkers. These findings show that a higher consumption of fresh and minimally processed foods and the adequacy of the nutritional status are protective factors for the inflammatory process.

RESUMEN

OBJECTIVE: To analyze the association between modifiable behavioral risk factors for non-communicable diseases and sleep parameters in Brazilian adolescents. METHODS: This was a cross-sectional study that used data from the RPS Cohort Consortium, São Luís, Brazil for the follow-up of adolescents aged 18-19 years (n = 2,515). The outcomes were excessive daytime sleepiness (Epworth Sleepiness Scale - ESS) and sleep quality (Pittsburgh Sleep Quality Index - PSQI). The exposures of interest were the behavioral risk factors for non-communicable diseases (NCDs): screen time, physical inactivity, alcohol, smoking, illicit drugs, caffeine intake, and consumption of sugar-sweetened beverages. Excess weight was considered a possible mediator of this association between the exposures of interest and the outcomes. The models were analyzed by modeling with structural equations. RESULTS: Physical inactivity (standardized coefficient, SC = 0.112; p = 0.001), higher consumption of alcohol (SC = 0.168; p = 0.019) and of sugar-sweetened beverages (SC = 0.128; p < 0.001) were associated with excessive daytime sleepiness in adolescents; better socioeconomic status was also associated with this outcome (SC = 0.128; p < 0.001). Physical inactivity (SC = 0.147; p < 0.001) and higher consumption of sugar-sweetened beverages (SC = 0.089; p = 0.003) were also associated with poor sleep quality. Overweight was neither a mediator nor associated with sleep quality or excessive daytime sleepiness. CONCLUSIONS: The main modifiable behavioral risk factors for NCDs are associated with worse sleep parameters already in adolescence, which serves as a warning toward the accumulation of risks for sleep disorders in the future.

RESUMEN

OBJECTIVE: To investigate the effects of depressive symptoms in childhood on the intellectual development of young adults. METHODS: Study conducted with a birth cohort of São Luís, Maranhão, Brazil, composed of 339 participants evaluated between 7 and 9 years and between 18 and 19 years. Structural equation modeling (young adult education, sex, race/color) and childhood variables (nutritional status, depressive symptoms, cognitive function, head of household's and mother's education, family income) were used. In addition, head of household's occupation, mother's age, and presence of partner were tested as determinants of adults' intelligence quotient (IQ). RESULTS: Presence of depressive symptoms in childhood triggered a reduction of 0.342 in standard deviation (SD) and -3.83 points in the average IQ of adults (p-value < 0.001). Cognitive function in childhood had a total and direct positive effect (standardized coefficient [SC] = 0.701; p-value < 0.001) on IQ, increasing 7.84 points with each increase in level. A positive indirect effect of child nutritional status (SC = 0.194; p-value = 0.045), head of household's (SC = 0.162; p-value = 0.036), and mother's education was identified, the latter mediated by cognitive function in childhood (SC = 0.215; p-value = 0.012) on the IQ of young people. CONCLUSION: Presence of depressive symptoms in childhood triggered a long-term negative effect on intelligence, reducing the IQ score in adulthood.

RESUMEN

BACKGROUND: Ultra-processed Food (UPF) consumption can play a role in the pathogenesis and progression of asthma. The aim of this study was to evaluate the association between the consumption of UPF and asthma. METHODS: This cross-sectional study included 1857 adults aged 23-25 years from the Ribeirão Preto-SP birth cohort (1978/1979). The exposure variable was the consumption of UPF (expressed as their percentage contribution to energy intake-% total caloric value [%TCV] and their percentage contribution to the amount of food ingested-%grams), which was assessed with a food frequency questionnaire. Asthma was the outcome and was defined based on a positive methacholine challenge test and the presence of wheezing, chest tightness, or shortness of breath over the last 12 months. Poisson regression with robust variance was used to estimate the association between these variables. Unadjusted analyses and analyses adjusted for sex, age, household income, smoking, and physical activity level were performed. RESULTS: The prevalence of asthma in the sample was 13.2%. The mean total consumption of UPF was 37.9 ± 11.2% TCV (corresponding to 35.1 ± 15.1% grams). There was no association between the consumption of UPF and asthma in adults. CONCLUSION: This study provides no evidence for an association between the consumption of UPF and asthma in young adults.

RESUMEN

Trend studies on the model of birth in Brazil show a scenario of successive linear increases in cesarean rates. However, they ignore possible changes in the temporal evolution of this delivery modality. Thus, this study aimed to evaluate possible inflection points in cesarean rates in Brazil, its macro-regions, and federated units, as well as to estimate projections for 2030. A time series with information on cesarean sections from 1994 to 2019 from the SUS Department of Informatics was used. Autoregressive integrated moving average and joinpoint regression models were used to obtain cesarean rate projections and trends, respectively. Caesarean rates showed a significant upward trend over the 26 study years at all levels of aggregation. On the other hand, when considering the formation of segments, a stabilization trend was observed both in the country and in the South and Midwest regions, starting in 2012. Rates tended to increase in North and Northeast and significantly decrease in Southeast. Projections show that in 2030, 57.4% of births in Brazil will be cesarean, with rates higher than 70% in Southeast and South regions.


Os estudos de tendência sobre a via de nascimento no Brasil têm revelado um cenário de sucessivos aumentos lineares nas proporções de cesariana. Entretanto, a possibilidade de mudanças na evolução temporal da via cirúrgica não tem sido considerada. Dessa forma, objetivou-se verificar possíveis pontos de inflexão na proporção de cesarianas no Brasil, macrorregiões e unidades federativas, bem como estimar suas projeções para o ano de 2030. Utilizou-se a série temporal com as cesarianas notificadas no Departamento de Informática do SUS no período de 1994 a 2019. Foram utilizados modelos autorregressivos integrados de médias móveis e de regressão joinpoint para obtenção de projeções e de tendências das proporções de cesariana, respectivamente. As proporções de cesarianas apresentaram tendência significativa de aumento ao longo dos 26 anos de estudo em todos os níveis de agregação. Por outro lado, quando se considera a formação de segmentos, observa-se tendência de estabilização no país e nas regiões Sul e Centro-Oeste, a partir de 2012. Norte e Nordeste apresentaram tendência de aumento e o Sudeste, de queda significativa. Projeções indicam que no ano de 2030, 57,4% dos nascimentos no país ocorrerão por via cirúrgica e que nas regiões Sudeste e Sul, serão observadas proporções superiores a 70%.

RESUMEN

(1) Background: Adolescence is characterized by changes in eating habits, with increased consumption of ultra-processed foods and reduced intake of unprocessed or minimally processed foods, which can affect body image satisfaction. Thus, this study aims to verify the association of food consumption according to the degree of processing with body image (dis)satisfaction in adolescents from the 1997/1998 birth cohort of São Luís, Maranhão. (2) Methods: A cross-sectional study was conducted with 2515 adolescents aged between 18 and 19. Food consumption was stratified based on the NOVA classification in culinary preparations, processed foods, and ultra-processed foods, categorized into tertiles. Body image (dis)satisfaction was evaluated based on the Stunkard Body Scale and was classified as satisfaction, dissatisfaction with thinness, and dissatisfaction with excess weight. Multinomial logistic regression was used for associations. (3) Results: Among the adolescents, 77% considered themselves dissatisfied with their body image, with 42.8% dissatisfied with being thin and 34.2% dissatisfied with excess weight. However, food consumption, according to the degree of processing, was not associated with body image (dis)satisfaction. (4) Conclusion: This work highlighted the prevalence of body image dissatisfaction among adolescents but found no association between body (dis)satisfaction and food consumption according to the degree of processing.

RESUMEN

Obesity is a recognized risk factor for the development of cardiometabolic outcomes. Therefore, it is essential to evaluate anthropometric and body composition indicators used for its diagnosis. This study aimed to assess the diagnostic performance of body fat percentage (BF%), fat mass index (FMI) and body mass index (BMI) for detecting cardiometabolic outcomes in adults. A cross-sectional study was conducted involving adults at 30 years of age from Pelotas, RS (n = 3517) and at 37-39 years from Ribeirão Preto, SP (n = 1696). Receiver operating characteristic (ROC) curves were used to determine the cut-off points for predicting cardiometabolic risk factors, including altered blood pressure, blood glucose, triglycerides, total cholesterol, low-density lipoprotein cholesterol (LDL-c), high-density lipoprotein cholesterol (HDDL-c), C-reactive protein and glycated hemoglobin. The cut-off points of BF% ranged from 25.2 to 27.8 in men and from 37.4 to 39.7 in women at 30 years, and from 26.1 to 27.8 in men and from 38.5 to 42.2 in women at 37-39 years. For FMI (kg/m2), the cut-off points ranged from 6.3 to 7.5 in men and from 9.5 to 10.8 in women at 30 years, and from 7.3 to 7.8 in men and from 10.2 to 12.2 in women at 37-39 years. The BMI cut-off points (kg/m2) ranged from 26.3 to 27.3 in men and from 25.4 to 27.2 in women at 30 years, and from 28.3 to 29.0 in men and from 27.2 to 29.6 in women at 37-39 years. The areas under the curve were similar for the three indicators, ranging from 0.523 to 0.746. BMI showed a performance similar to that of the body fat-based indicators in identifying cardiometabolic outcomes. The cut-off points of the three indicators showed acceptable discriminatory power in subjects with cardiometabolic risk factors.

RESUMEN

OBJECTIVE: To describe the prevalence of insufficient sleep duration, long sleep latency, terminal or maintenance insomnia, subjective sleep quality, and excessive daytime sleepiness among participants of birth cohorts conducted in three Brazilian cities, and to evaluate differences in prevalence rates within cohorts according to sociodemographic characteristics. METHODS: Cross-sectional analyses involving adolescents and adults participating in four birth cohorts conducted in Ribeirão Preto (RP78 and RP94), Pelotas (PEL93) and São Luís (SL97/98). Sleep duration, latency, terminal or maintenance insomnia, and subjective sleep quality were obtained through the Pittsburgh Sleep Quality Index; and excessive daytime sleepiness was assessed using the Epworth Sleepiness Scale. Differences in the prevalence of the outcomes were analyzed in each cohort according to sociodemographic characteristics (skin color, marital status, socioeconomic status, study and working at the time of the interview) stratified by sex. RESULTS: Insufficient sleep duration was the most common outcome at the four cohorts, with higher frequency among men. Long latency was more frequently reported by young adult women in RP94 and PEL93 cohorts, and insomnia by women of the four cohorts, when compared to men of the same age. Women generally suffered more from excessive daytime sleepiness and evaluated the quality of their sleep more negatively than men. In addition to sex, being a student and working were associated with the largest number of outcomes in both sexes. CONCLUSION: Sleep disorders are more prevalent in women, reinforcing the need for greater investment in sleep health in Brazil, without disregarding gender and socioeconomic determinants.

RESUMEN

Children have an increased likelihood of becoming carriers of the chronic hepatitis B virus. A total of 1,381 children and adolescents were assessed in five municipalities of Maranhao State, Brazil, for detection of anti-HBc, HBsAg and anti-HBs serologic markers and sociodemographic and behavioral features. Among those who were HBsAg negative and anti-HBc negative, the proportion of anti-HBs positives was calculated after the individuals had completed the vaccination schedule. The robust variance of the Poisson's regression model was used in order to have adjusted tables and calculate the prevalence ratio. Multivariate analysis was performed to identify the factors associated with the prevalence of anti-HBc with or without HBsAg and the vaccine response. It was observed that 163 children were anti-HBc positive and nine individuals were HBsAg positive. The factors associated with the infection were: municipality of residence (residing in Morros municipality or Humberto de Campos municipality), residence in a rural area, aged between 13 and 15 years old, and illicit drug use. The percentage of individuals who were anti-HBc negative and received all three doses of the vaccine was 48.5%. Among these, only 276 (38.9%) had antibodies at protective concentrations. In an adjusted analysis, Morros municipality presented an increased positivity of vaccine response (p < 0.001), and the age ranging between 6 and 10 years old presented a reduced frequency of response. This study reveals a high prevalence of current and past HBV infection within the targeted age group which, in addition to the low vaccination coverage and serological responses, raises concerns about the management of prevention measures, especially the quality of vaccination in these locations.

RESUMEN

Controversial results have been reported on the association between mode of delivery and patient satisfaction. This study investigates which mode of delivery leads to greater satisfaction with hospital admission for childbirth. A cohort study was conducted with data from the Birth in Brazil study, which began in 2011. A total of 23,046 postpartum women were included from a random sample of hospitals, selected by conglomerates with a three level stratification. At the first follow-up, 15,582 women were re-interviewed. Mode of delivery, dichotomized into vaginal or cesarean section, and confounders were collected before hospital discharge. The outcome maternal satisfaction, investigated as a 10-item unidimensional construct, was measured by the Hospital Birth Satisfaction Scale up to six months after discharge. We used a directed acyclic graph to define minimal adjustment variables for confounding. The effect of mode of delivery on satisfaction was estimated using a structural equation model with weighting by the inverse of the probability of selection, considering the complex sampling design. The weight was estimated considering the different sample selection probabilities, the losses to follow-up, and the propensity score, which was estimated in a logistic regression model. The analysis revealed no significant difference in satisfaction with hospitalization for childbirth between respondents who had vaginal delivery and cesarean section in the adjusted analysis (standardized coefficient = 0.089; p-value = 0.056). Therefore, women who had vaginal delivery and cesarean section were equally satisfied with their hospitalization for childbirth.

RESUMEN

AIM: To analyze the association between neonatal near miss and infant development at two years. METHODS: Data from two birth cohorts, one conducted in Ribeirão Preto (RP)/São Paulo and the other in São Luís (SL)/Maranhão, were used. The cognitive, motor and communication development of children was evaluated using the Bayley Scales of Infant and Toddler Development, Third Edition (Bayley-III). The following criteria were used for the definition of NNM: birth weight < 1,500 g, 5-min Apgar score < 7, gestational age < 32 weeks, and report of congenital malformations. The relationship between neonatal near miss and development was assessed using the weighted propensity score from the Inverse Probability of Treatment Weighting (IPTW). A directed acyclic graph was built to select the adjustment variables. RESULTS: A total of 1,050 mother-newborn dyads were evaluated in SL and 1,840 in RP. Regarding outcomes in SL and RP, respectively, 2.4% and 17.3% of the children were not competent in the cognitive domain, 12.1% and 13.3% in the receptive communication domain, 39.2% and 47.1% in the expressive communication domain, 20.7% and 12.6% in the fine motor domain, and 14.3% and 13.8% in the gross motor domain. The prevalence of neonatal near miss was 5.4% in SL and 4.3% in RP. Unadjusted analysis showed an association of neonatal near miss with fine motor development in SL and RP and with the cognitive, receptive communication, expressive communication, and gross motor domains only in RP. These associations remained after adjusted analysis. CONCLUSION: Neonatal near miss is a risk factor for developmental delays.
