BackgroundType 1 diabetes patients have a higher risk of developing hypoglycemia or hyperglycemia during physical activity, which may compromise their safety during exercise but results regarding the exercise capacity of patients with type 1 DM when compared to control subjects have been contradictory.AimTo evaluate if type 1 diabetes affects the capacity of adolescents to exercise.MethodsThe study enrolled 37 adolescents in stage 2–4 of the Tanner scale, aged from 10 to 14 years, 21 with type 1 diabetes and 16 without any chronic diseases. All subjects performed an incremental submaximal exercise test in a cycle ergometer. At the end of every test stage, glycemia and blood lactate levels were measured. During the test, heart rate was monitored and the Borg rating of perceived exertion (RPE) was used to assess fatigue.ResultsThe two groups displayed no significant differences in anthropometric variables. The response to exercise, as evaluated by Borg RPE (p = 0.829), maximum oxygen uptake (VO2max) (p = 0.977), heart rate (p = 0.998), maximum load (p = 0.977), absolute load at lactate threshold (p = 0.377) and relative load at lactate threshold (p = 0.282), was also similar between the control and the type 1 diabetes group. Finally, there were no significant correlations between HbA1c levels, VO2max, duration of disease and pre-test glycemia levels.ConclusionsWe detected no significant differences in lactate threshold, VO2max and heart rate during exercise between healthy adolescents and non-sedentary adolescents with type I diabetes, indicating that both groups had similar physical fitness and, therefore, that type 1 diabetes is not an obstacle for physical activity. This study was approved by the ethical committee of the Hospital Israelita Albert Einstein (Ethical Committee Number: 53638416.9.0000.0071) and free and informed consent was obtained from all participants and their legal representatives.

Primary cytomegalovirus (CMV) infection during pregnancy is the leading infectious cause of congenital neurological disabilities. Diagnosis of maternal primary CMV infection and fetal compromise can be difficult, as well as the fact that most infected child are asymptomatic at birth, which makes binomial CMV and pregnancy challenging. The treatment of pregnant women with CMV hyperimmunoglobulin (CMV-HIG) has shown promising results. However, as far as we know, no randomized trials of immunoglobulin therapy of CMV-infected fetuses are ongoing. We describe CMV-HIG administration for twin pregnancy as maternal and fetal infection early in gestation. The epidemiology, clinical manifestations, prevention strategies and treatment of CMV infections are reviewed.

Objective To assess whether the spontaneous breathing test can predict the extubation failure in pediatric population.Methods A prospective and observational study that evaluated data of inpatients at the Pediatric Intensive Care Unit between May 2011 and August 2013, receiving mechanical ventilation for at least 24 hours followed by extubation. The patients were classified in two groups: Test Group, with patients extubated after spontaneous breathing test, and Control Group, with patients extubated without spontaneous breathing test.Results A total of 95 children were enrolled in the study, 71 in the Test Group and 24 in the Control Group. A direct comparison was made between the two groups regarding sex, age, mechanical ventilation time, indication to start mechanical ventilation and respiratory parameters before extubation in the Control Group, and before the spontaneous breathing test in the Test Group. There was no difference between the parameters evaluated. According to the analysis of probability of extubation failure between the two groups, the likelihood of extubation failure in the Control Group was 1,412 higher than in the Test Group, nevertheless, this range did not reach significance (p=0.706). This model was considered well-adjusted according to the Hosmer-Lemeshow test (p=0.758).Conclusion The spontaneous breathing test was not able to predict the extubation failure in pediatric population.

OBJECTIVE:To test whether weight and the weight gain rate during different age periods are associated with being overweight/obese at 10 years of age.METHODS:A nested case-control study was performed in a clinical historic cohort that was selected based on medical records from the Albert Einstein Hospital Social Program in São Paulo, Brazil. A sample of 378 eutrophic and overweight/obese children was analyzed.RESULTS:After adjusting for birth weight and gestational age, the likelihood of being overweight/obese at 10 years of age was 4.04-fold greater when progressing from one quartile of weight gain to the immediately superior quartile in the first semester of life and 3.24-fold greater when this occurred from 2-5 years of age. A one-quartile change in weight gain in the first semester was associated with a 0.5 z-score increase in BMI at age 10. A robust independent effect of weight at age 5 confirmed that earlier weight gain was an important predictor.CONCLUSIONS:The amount of weight gain during the first 6 months of life and between 2 and 5 years of age and weight at age 5 were important predictors of overweight/obesity at 10 years of age.

Objective:To identify the factors that determine unintentional injuries in children living in the community of Paraisopolis, in the city of São Paulo, Brazil.Methods:A cross-sectional and non-controlled study. Data collected during 4 consecutive months through questionnaires filled out for the Einstein Program in Paraisopolis Community included identification of the patient and his/her family, scholarity level, housing conditions, storage of hazardous products, access to the streets and concrete slab ceilings, supervision, and trauma mechanism involved. The observed data were treated as absolute and relative frequencies; χ2, Fisher's exact test, Student's t test, and Mann-Whitney's tests were implemented, with a significance level of 5% (p<0.05).Results:A total of 1,490 questionnaires were analyzed. There was a predominance of trauma within boys (59.6%) and the medium age was 5.2 years. The predominant educational level of the parents was incomplete junior school education. The main caregiver identified was the mother (69.4%). Among the children that suffered trauma, 56.4% belonged to large families (≥6 people), lived in houses up to three rooms, and a family income up to R$ 1,000.00 (76.6%). Easy access to hazardous materials was considerable and free access to concrete slab ceilings was reported in 92.8% of the cases. The main trauma mechanisms were falls and burns. In this study, the child victim of a fall was aged under 5 years.Conclusion:Small children that live in a hazardous environment have a significant tendency to suffering trauma
