The main goal of this manuscript was to investigate the neurodevelopment of children exposed by Zika virus in the intrauterine period who are asymptomatic at birth. Newborns with documented Zika virus exposure during the intrauterine period who were asymptomatic at birth were followed in the first two years of life for neurodevelopment using Bayley III test. Children were classified as having normal or delayed neurodevelopment for age based on most recent Bayley III evaluation results. Eighty-four infants were included in the study. The first Bayley III evaluation was performed at a mean chronological age of 9.7±3.1 month; 13 children (15%) had a delay in one of the three domains, distributed as follow: 10 (12%) in the language domain and 3 (3.5%) in the motor domain. The most recent Bayley III evaluation was performed at a mean age 15.3±3.1 months; 42 children (50%) had a delay in one of the three domains: 4 (5%) in cognition, 31 (37%) in language, and 20 (24%) in motor performance. There were no statistical differences in Gender, Gestational Age, Birth Weight and Head Circurference at birth between children with normal and delayed neurodevelopment for age. A very high proportion of children exposed ZIKV during pregnancy who were asymptomatic at birth demonstrated a delay in neurodevelopment, mainly in the language domain, the first two years of life.
ResumoObjetivo: Determinar a influência da sucção não-nutritiva e da estimulação oral nas taxas de amamentação na alta hospitalar, aos 3 meses e 6 meses de idade corrigida em recém-nascidos pré-termo de muito baixo peso ao nascer. Métodos:Foram randomizados 98 recém-nascidos pré-termo de muito baixo peso ao nascer, e 96 permaneceram no estudo até o 6º mês de idade corrigida. Os recém-nascidos foram randomizados em grupo experimental e grupo controle. O grupo experimental recebeu um programa de estimulação (sucção não-nutritiva associado à estimulação sensório-motora-oral), e o grupo controle, um procedimento simulado a partir do momento em que atingiam alimentação plena até a alimentação oral completa.Resultados: Observou-se que 59 (61,5%) recém-nascidos estavam em amamentação na alta, 31 (32,6%) aos 3 meses e apenas 18 (18,75%) aos 6 meses de idade corrigida. Na alta, 47% dos recém-nascidos do grupo controle e 76% do grupo estimulado estavam em amamentação. Aos 3 meses, 18% do grupo controle e 47% do grupo estimulado continuavam em amamentação, e aos 6 meses, 10% do grupo controle e 27% do grupo estimulado. Houve diferença estatística nos três períodos estudados, favorecendo o grupo estimulado (p < 0,05). Conclusão:O presente estudo demonstra que a sucção não-nutritiva, associada à estimulação oral, pode contribuir para a melhoria das taxas de amamentação em pré-termos de muito baixo peso ao nascer.J Pediatr (Rio J). 2008;84(5):423-427: Recém-nascido prematuro, aleitamento materno, comportamento da sucção. AbstractObjective: To determine the influence of non-nutritive sucking and oral stimulation programs on breastfeeding rates at discharge, at 3 and at 6 months of corrected age in preterm infants with very low birth weight.Methods: Preterm infants were randomized into experimental and control groups. Ninety-eight preterm infants were randomized and 96 remained in the study until reaching the corrected age of 6 months. The experimental group received sensory-motor-oral stimulation and non-nutritive sucking, while infants in the control group received a sham stimulation program. Both were administered from reaching enteral feeding (100 kcal/kg/day) until the beginning of oral feeding.Results: Fifty-nine infants (61.5%) were breastfeeding at the time of hospital discharge, 31 (36.9%) at 3 months, and only 18 (20.5%) at 6 months of corrected age. At discharge, 46.9% of the control group and 76.5% of the experimental group were breastfeeding. There were statistically significant differences between rates of breastfeeding at discharge (47 vs. 76%), 3 months (18 vs. 47%) and 6 months after discharge (10 vs. 27%). The experimental group showed significantly higher rates of breastfeeding (p < 0.05). Conclusion:Non-nutritive sucking, associated with oral stimulation programs, can contribute to the improvement of breastfeeding rates among preterm infants with very low birth weight.J Pediatr (Rio J). 2008;84(5):423-427: Preterm infant, breastfeeding, sucking behavior.
OBJECTIVE:To analyze factors associated with failure to breastfeed during the first hour of life, especially the influence of time of delivery of rapid HIV test results. METHODS:Cohort study, beginning with the administration of the rapid test and ending the first time the baby is breastfed. The study population included 944 delivering mothers that received rapid HIV testing with a negative result in five Baby-Friendly hospitals of the High-Risk Pregnancy System in the city of Rio de Janeiro, Southeastern Brazil, in 2006. Trained interviewers obtained data from laboratory and patient charts and interviewed mothers shortly after delivery. The influence of sociodemographic variables and antenatal and delivery care characteristics on failure to breastfeed during the first hour of life was determined through a multilevel model. RESULTS:Among participants, 15.6% received the result of rapid HIV testing before delivery, 30.8% after delivery, and 53. 6% had not yet been informed of their results at the time of the interview. Prevalence of failure to breastfeed in the first hour of life was 52.5% (95% CI: 49.3;55.8). After adjustment, having received the result of rapid testing only after delivery doubled the risk of failing to breastfeed in the first hour (RR=2.06; 95% CI: 1.55;2.75). Other risk factors included nonwhite skin color, maternal income of up to one minimum wage, delivery by C-section, mother's lack of desire to breastfeed at birth, and mother's report that the hospital staff did not listen to her. Lack of knowledge of HIV testing from the mother's part was found to be a protective factor. CONCLUSIONS:The major risk factor for not breastfeeding in the first hour of life was failure to receive the results of rapid HIV testing prior to delivery. HIV testing should be made widely available during antenatal care; rapid testing should be performed upon admission, only when indicated, and with active search and prompt delivery of results to expecting mothers.
Recurrent haemarthroses often lead to chronic synovitis in patients with haemophilia and von Willebrand disease. Radioactive synovectomy with yttrium-90 (⁹⁰Y) citrate is frequently used to treat this complication, usually with good results. Since 2006, the Nuclear Energy Research Institute (IPEN, Sao Paulo, Brazil) has produced hydroxyapatite particles labelled with ⁹⁰Y for radioactive synovectomy. The aim of this study was to compare the results achieved by both forms of ⁹⁰Y in the treatment of haemophilic synovitis. We included 221 joints from 136 patients (age range: 6-20 years), treated by one of the two radiopharmaceuticals, at the Hemocenter of Mato Grosso, Brazil. The outcomes analysed were the annual frequency of haemarthrosis, articular pain and joint range of motion before and 1 year after RS. Similar results were achieved regardless of whether ⁹⁰Y hydroxyapatite or ⁹⁰Y citrate was used, and results were independent of the joint type, age, gender, radiologic stage and presence of inhibitors. ⁹⁰Y hydroxyapatite appears to be equivalent to the reference product ⁹⁰Y citrate in the treatment of chronic synovitis associated with bleeding disorders.
The implications of Zika Virus exposure in pregnancy for early infant growth remains poorly described. The main goal of this study is to compare the growth, body composition, and feeding modality of infants in the first three months of life by prenatal Zika Virus exposure status. We selected an analytical cohort of 115 infants born without microcephaly, comprising 56 infants with qRT-PCR confirmed exposure to ZIKV during gestation and 59 infants born to women with presumptively no evidence of ZIKV in pregnancy. Infants were evaluated at birth, 1 and 3 months of age in terms of anthropometrics, body composition All the results were adjusted by maternal age, maternal BMI and gestational age. We observe no differences between anthropometric measurements at birth. Mothers in exposed group showed higher BMI. At 1 month and 3 months of age there were differences in mid arm circumference, arm muscle circumference and fat free mass. Weight and length was less in the ZIKV exposed in pregnancy infants and statistically different at 3 month of age. The findings of this investigation provide new evidence that ZIKV exposure in pregnancy may be associated with differences in body composition.
Background The COVID-19 pandemic has affected the entire world, and the vaccine has emerged as a source of hope for return to normal life. Still, various countries have reported high vaccine hesitancy rates. It is important to know the vaccine hesitancy profile in Brazil to help design adequate communication strategies. Methods A voluntary, anonymous online survey was conducted from January 22 to 29, 2021, including resident Brazilian adults to assess factors related to vaccine hesitancy. Sociodemographic and epidemiological data were analyzed. A bivariate analysis was conducted with the independent variables, with vaccine hesitancy as the outcome variable, and a multivariate logistic model was used to calculated adjusted odds ratios. Results The sample included 173,178 respondents, and vaccine hesitancy was found in 10.5%. The principal factors associated with vaccine hesitancy were the following: assigning importance to the vaccinés efficacy (AOR=16.39), fear of adverse reactions (AOR = 11.23), and assigning importance to the vaccinés country of origin (AOR=3.72). Other risk factors were the following: male gender (AOR=1.62), having children (AOR=1.29), 9 years of schooling or less (AOR=1.31), living in the Central-West region (AOR=1.19), age ≥ 40 years (AOR=1.17), and monthly income < U$788.68 (AOR=1.13). The two vaccines available in Brazil, Covishield and CoronaVac, showed similar confidence, 80.13% and 76.36%, respectively, despite the higher rejection of the latter vaccinés Chinese origin. Interpretation: This online survey confirms the low vaccine hesitancy rate among Brazilians and allowed the identification of a profile that can assist the elaboration of communication strategies to increase vaccine adherence.

These results are consistent with the functional normality of the brainstem structure and its lack of correlation with microcephaly, suggesting that the disruption produced by the ZV infection does not act in the cell proliferation phase, but mostly in the processes of neuronal migration and differentiation in the telencephalon.
