Prenatal repair of gastroschisis using partial carbon dioxide insufflation fetoscopy: lessons learned.

We report the long-term outcomes of a case of prenatal gastroschisis repair using a fully percutaneous fetoscopic approach with partial carbon dioxide insufflation. Surgery was performed as an experimental procedure before the scheduled elective birth. The fetal intestines were successfully returned to the abdominal cavity without any fetal or maternal complications. Ultrasonography performed 24 hours later revealed bowel peristalsis and no signs of fetal distress. After 48 hours, partial extrusion of the small bowel was observed, and the fetus was delivered. Gastroschisis repair was immediately performed upon delivery using the EXIT-like procedure as per our institutional protocol. The newborn did not require assisted mechanical ventilation, was discharged at 14 days of age and was then exclusively breastfed. At 3-year follow-up, the patient had no associated gastroschisis-related complications. This is the first case of prenatal repair of gastroschisis, which provides baseline knowledge for future researchers on the potential hurdles and management of prenatal repair.

Effects of High-Intensity Interval Training on Central Blood Pressure: A Systematic Review and Meta-Analysis. / Efeitos do Treinamento Intervalado de Alta Intensidade sobre a Pressão Arterial Central: Uma Revisão Sistemática e Metanálise.

Central blood pressure (cBP) is considered an independent predictor of organ damage, cardiovascular events and all-cause mortality. Evidence has shown that high intensity interval training (HIIT) is superior to moderate-intensity continuous training (MICT) for improving cardiorespiratory fitness and vascular function. However, the effects of these aerobic training modalities on cBP have not yet been properly reviewed.This meta-analysis aims to investigate to effects of HIIT versus MICT on cBP.We conducted a meta-analysis of randomized controlled trials that compared HIIT versus MICT on cBP. Primary outcomes were measures of central systolic blood pressure (cSBP) and central diastolic blood pressure (cDBP). Peripheral systolic blood pressure (pSBP) and diastolic blood pressure (pDBP), pulse wave velocity (PWV) and maximal oxygen uptake (VO2max) were analyzed as second outcomes. Meta-analysis of mean differences (MD) was conducted using the random effects model.Our study included 163 patients enrolled in six trials. We found that HIIT was superior to MICT in reducing the cSBP (MD = -3.12 mmHg, 95% CI: -4.75 to -1.50, p = 0.0002) and SBP (MD = -2.67 mmHg, 95% CI: -5.18 to -0.16, p = 0.04), and increasing VO2max(MD = 2.49 mL/kg/min, 95% CI: 1.25 to 3.73, p = 0.001). However, no significant differences were reported for cDBP, DBP and PWV.HIIT was superior to MICT in reducing the cSBP, which suggests its potential role as a non-pharmacological therapy for high blood pressure.

A pressão arterial central (PAc) é considerada um preditor independente de lesão de órgão, eventos cardiovasculares e mortalidade por todas as causas. Evidências mostram que o treino intervalado de alta intensidade (HIIT) é superior ao treino contínuo de intensidade moderada (MICT) na melhoria da aptidão cardiorrespiratória e da função vascular. No entanto, os efeitos dessas modalidades de treino aeróbico sobre a PAc não foram propriamente revisados. Esta metanálise tem como objetivo investigar os efeitos do HIIT versus MICT sobre a PAc.Conduzimos uma metanálise de ensaios controlados randomizados que compararam HIIT versus MICT sobre a PAc. Os desfechos primários foram Pressão Arterial Sistólica (PAS) central (PASc) e Pressão Arterial Diastólica central (PADc). A PAS periférica (PASp), a PAD periférica (PADp), a Velocidade de Onda de Pulso (VOP) e a captação máxima de oxigênio (VO2max) foram analisadas como desfechos secundários. A metanálise das diferenças médias (DM) foi conduzida usando modelos de efeitos aleatórios.Nosso estudo incluiu 163 pacientes recrutados em seis ensaios. Encontramos que HIIT foi superior ao MICT em reduzir PASc (DM = -3,12 mmHg, IC95% -4,75 ­ 1,50, p = 0,0002) e PAS (DM = -2,67 mmHg, IC95% -5,18 ­ -0,16, p = 0,04) e aumentar VO2max (DM = 2,49 mL/Kg/min, IC95% 1,25 ­ 3,73, p = 0,001). No entanto, não foram relatadas diferenças quanto à PADc, PAD ou VOP. O HIIT foi superior ao MICT em reduzir PASc, sugerindo seu potencial papel como uma terapia não farmacológica para a pressão arterial elevada.

Non-Invasive Methods and the Use of Infiltrating Resins for the Control of Caries Progression in Deciduous Teeth: A Systematic Review and Meta-Analysis

ABSTRACT Objective: To evaluate the influence of non-invasive treatment associated with the use of infiltrating resin for managing caries lesions in primary teeth. Material and Methods: A systematic review was performed by selecting articles from 6 online databases, using a search algorithm and eligibility criteria for data extraction and data synthesis for the papers included. Clinical trials involving primary teeth with incipient caries lesions (1/2 of the enamel or 1/3 of the outer dentin) were included, presenting full text and answering the study's guiding question. This study used the RoB 2 tool for the risk of bias assessment and GRADE for certainty of evidence. Random effects meta-analyses were implemented, and lesion progression treatment effects were estimated through relative risk (RR) and associated 95% confidence intervals. Results: A total of 440 studies were found. After analyzing the inclusion criteria and removal of duplicates, eight studies were analyzed for quality evidence. Five of the eight studies included in this review contributed to the meta-analysis, all with some reflections regarding the risk of bias. Overall, the results of the meta-analysis showed that non-invasive treatment, when associated with the use of infiltrating resins, significantly reduced the risk of caries progression in relation to the treatment without this addition for follow-up periods ranging from 12 months to 2 years (RR 0.51 [0.40-0.65]). Conclusion: There is moderate certainty of evidence that the use of infiltrating resins associated with non-invasive treatments decreases the risk of caries progression in primary teeth with incipient caries lesions (1/2 of the enamel or 1/3 of the dentin outer) when combined with non-invasive control methods alone.

Efficacy and Safety of Oral Midazolam Sedation Compared with its Combination with Hydroxyzine Use in Pediatric Dentistry: A Systematic Review

ABSTRACT Objective: To assess the efficacy and safety of the use of midazolam as monotherapy, compared to the associated use of midazolam and hydroxyzine for minimum and moderate sedation of children in dental offices, using data obtained from clinical trials. Material and Methods: A systematic review protocol was developed and registered on PROSPERO (CR42020208633). An electronic search was carried out in Pubmed, Lilacs, Science Direct, Open Gray, Web of Science, and central Cochrane Library. No language restrictions were included. Clinical trials were carried out with children aged 0-12 years, using midazolam as monotherapy compared to the use of midazolam associated with hydroxyzine to verify the effectiveness and safety of oral sedation. The quality of the studies was individually assessed and grouped using the RoB 2 (Revised Cochrane risk-of-bias tool for randomized trials) and GRADE (Grading of Recommendations Assessment, Development and Evaluation) systems, respectively. Results: A total of 749 studies were found. After analyzing the inclusion and removal of duplicates, two studies were analyzed for the quality of evidence. Through this analysis, it was possible to verify the very low level of scientific evidence on the superiority of the efficacy and safety of the combined use of midazolam and hydroxyzine for oral sedation in children in dental offices. Conclusion: The conflicting results and limitations of the studies enabled to establish that there is insufficient evidence to support the use of these drugs combined. There is only evidence for the use of midazolam as monotherapy.

Effects of exercise modality and intensity on the CD4 count in people with HIV: a systematic review and meta-analysis.

The purpose of this study was to assess the effect of training modality and exercise intensity on the modulation of lymphocytes CD4 count in people living with HIV (PLWH). A search for randomised controlled trials was performed using five databases (PubMed/Medline, Cochrane, LILACS, Scielo and CAPES). Meta-analyses of mean differences (MD) were conducted using a random-effects model to compare the effects of training modality and intensity on CD4 count. The CD4 count comparing physical training vs. control group (MD of CD4 was 54.58 cell/ml³ [CI 95% 15.58-93.59], p =< 0.01). In according to the subgroup analysis, only aerobic exercise has proved to have a significant effect on CD4 (MD 79.91 cell/ml³ [CI 95% 19.30-140.52], p =< 0.01). When exercise intensities were stratified, only intense training proved to have a significant effect on CD4 (MD 64.87 cell/ml³ [CI 95% 15.79-113.95], p =< 0.01). In meta-regression analysis showed that the aerobic training, as well, high the intensity training were predictors significant to the improvement of CD4 (p =< 0.01). Exercise training is an important strategy to assist in the treatment of PLWH. The aerobic training modality and the high intensity training were able to promote improve the modulation of CD4 count chronically in PLWH.

Effects of table tennis practice on balance and physical fitness in the elderly / Efeitos da prática de tênis de mesa no equilíbrio e aptidão física em idosos

ABSTRACT The Table Tennis game does not involve large displacements by the practitioner in the environment, a characteristic that can promote greater safety for the elderly in locomotor terms. In addition, it needs coordination, agility, speed of reaction, dynamic balance, which have been the focus of current recommendations of physical activity for the health of adults and the elderly. The aim of this study is to investigate the effects of table tennis practice on physical and functional fitness in the elderly. This quasi-experimental research with a parallel and controlled design. The sample consisted of 16 elderly people, allocated 8 in the experimental group (EG) and 8 in the control group (CG). The research lasted 18 weeks, with 2 weeks of evaluation (initial and final) and 16 weeks of intervention. Physical fitness assessments were carried out using the agility and balance and functional fitness tests. In the intra-group comparison (pre-post intervention), EG showed a significant difference for the variable agility (pre: 15.6 ± 1.2 s; post: 14.7 ± 0.7 s). Also, the EG showed a reduction in Area (pre: 11.00±3.32 cm2; post: 6.52±3.06 cm2), AP Amplitude (pre: 4.92±2.77 cm; post: 3.28±0.58 cm) and ML speed (pre: 2.77±1.07 cm/s; post: 2.31±1.03 cm/s) in the Tandem posture with eyes open. Our findings highlight the importance of a Table Tennis program, administered twice a week and consisted of low to moderate intensity activities, to promote a beneficial effect on the agility and balance of physically active elderly people.

RESUMO O jogo de Tênis de Mesa não envolve grandes deslocamentos do praticante no ambiente, característica que pode promover maior segurança ao idoso em termos locomotores. Além disso, precisa de coordenação, agilidade, velocidade de reação, equilíbrio dinâmico, que têm sido foco das atuais recomendações de atividade física para a saúde de adultos e idosos. O objetivo deste estudo é investigar os efeitos da prática de tênis de mesa na aptidão física e funcional de idosos. Esta pesquisa apresenta delineamento quase experimental com um desenho paralelo e controlado. A amostra foi composta por 16 idosos, alocados 8 no grupo experimental (GE) e 8 no grupo controle (GC). A pesquisa teve duração de 18 semanas, sendo 2 semanas de avaliação (inicial e final) e 16 semanas de intervenção. As avaliações da aptidão física foram realizadas por meio dos testes de agilidade e equilíbrio e aptidão funcional. Na comparação intragrupo (pré-pós intervenção), o GE apresentou diferença significativa para a variável agilidade (pré: 15,6 ± 1,2 s; pós: 14,7 ± 0,7s). Além disso, o GE apresentou redução na Área (pré: 11,00±3,32 cm2; pós: 6,52±3,06 cm2), Amplitude AP (pré: 4,92±2,77 cm; pós: 3,28±0,58 cm) e velocidade ML (pré: 2,77±1,07 cm/s; pós: 2,31±1,03 cm/s) na postura Tandem com os olhos abertos. Nossos achados destacam a importância de um programa de Tênis de Mesa, administrado duas vezes por semana e composto por atividades de baixa a moderada intensidade, para promover um efeito benéfico na agilidade e equilíbrio de idosos fisicamente ativos.

Efeitos antifúngico e antiaflatoxigênico de timol e carvacrol em Aspergillus flavus / Antifungal and antiaflatoxigenic activities of thymol and carvacrol against Aspergillus flavus

O objetivo deste estudo foi avaliar os efeitos do timol e carvacrol contra Aspergillus flavus e a produção de aflatoxinas. Foram determinadas a concentração inibitória mínima (CIM), o espectro fungitóxico e a atividade inibidora de micotoxinas pelo timol e carvacrol. Os resultados mostraram que timol e carvacrol exibiram ação fungicida de acordo com a CIM de 2500 e 30 µg mL-1, respectivamente. Tanto o timol quanto o carvacrol inibiram significativamente o crescimento de A. flavus (p<0,05) a partir de 600 e 15 µg mL-1, respectivamente. A biomassa fúngica, estimada pela determinação da concentração de ergosterol, foi significativamente reduzida (p <0,05) em 2500 µg mL-1 de timol e 250 µg mL-1 de carvacrol. O timol e o carvacrol exibiram efeitos antiaflatoxigênicos em 600 e 125 µg mL-1, respectivamente. O timol e o carvacrol exibiram atividade antifúngica, mas não exibiram alta atividade antiaflatoxigênica. Carvacrol e timol podem ser considerados como potentes compostos naturais antifúngicos contra A. flavus.

The aim of this study was to evaluate the effects of thymol and carvacrol upon production of aflatoxins by Aspergillus flavus and upon its growth. Minimal inhibitory concentration (MIC), fungitoxic spectrum and mycotoxin inhibition were assessed. Results showed thymol and carvacrol exhibited fungicidal action, as determined by MIC values of 2500 and 30 µg mL-1, respectively. Both thymol and carvacrol significantly inhibited growth of A. flavus (p<0.05) at concentrations of 600 and 15 µg mL-1, respectively. Fungal biomass, as estimated by determination of ergosterol concentration, was significantly reduced (p<0.05) at thymol concentrations of 2500 µg mL-1 and at carvacrol concentrations of 250 µg mL-1. Thymol and carvacrol exhibited antiaflatoxigenic effects at concentrations of 600 and 125 µg mL-1, respectively. While both thymol and carvacrol showed possessing antifungal activities, neither were highly antiaflatoxigenic. Carvacrol and thymol might be considered for use as potential antifungal natural compounds against A. flavus.

P-glycoprotein and multidrug resistance-associated protein-1 expression in acute myeloid leukemia: Biological and prognosis implications.

BACKGROUND: Despite the advances in the cure rate for acute myeloid leukemia (AML), a considerable number of patients die from the disease due to the occurrence of multidrug resistance (MDR). Overexpression of the transporter proteins, such as P-glycoprotein (Pgp) and multidrug resistance-associated protein (MRP), confers resistance to the treatment of these leukemias. METHODS: To analyze the expression of the Pgp and MRP1 in patients with AML and determine their correlation between expression and demographic, clinical, and laboratorial variables, bone marrow and peripheral blood samples from 346 patients with a diagnosis of AML were assessed for the expression of Pgp and MRP1 by flow cytometry. RESULTS: The expression of Pgp and MRP1 was found in 111 (32.1%) and 133 (38.4%) patients, respectively, with greater prevalence in older patients and lower in children, while also observing a high incidence in patients with refractory, recurrence, and secondary disease in comparison with the cases of de novo AML. Regarding the laboratory findings, we observed an association between the expression of Pgp and MRP1 and CD34, CD7, and also M7, M5a, and M2-AML of French-American-British classification. CONCLUSIONS: The results showed that the detection of MDR phenotype by flow cytometry can be a molecular marker for prognosis of patients with AML.

Tri-ponderal mass index as a tool for insulin resistance prediction in overweight adolescents: A cross-sectional study.

OBJECTIVE: The aims of this study were to assess the capacity of tri-ponderal mass index (TMI) to screen and predict insulin resistance (IR) in overweight Brazilian adolescents, comparing it with body mass index (BMI) predictive capacity; and to verify the IR predictive capacity of other assessment tools such as waist circumference (WC), and waist-to-height ratio (WHR). METHODS: A cross-sectional study was carried out with 217 overweight adolescents, from both sexes, between 12 and 18 y of age. The participants were classified as having IR according to a previous established cutoff point of ≤3.16. IR was determined by the homeostasis model assessment of insulin resistance. The other assessment tools were measured with standard protocols. RESULTS: There was no difference between TMI and BMI to explain the presence of IR. In girls, BMI presented a slightly better predictive capacity to explain IR than TMI. Moreover, WC was reported to be the most effective IR screening methods for girls. Receiver operating characteristic curves showed that TMI and BMI presented similar values of sensibility and specificity for boys. Nevertheless, BMI had a better sensibility and TMI had a better specificity for girls. Interestingly, WC demonstrated a strong sensibility for both sexes. CONCLUSIONS: TMI did not present a superior predictive accuracy for IR screening in overweight Brazilian adolescents when compared with BMI. TMI and BMI presented similar values of sensitivity and specificity for boys and WC a slightly superior IR predictive capacity for girls.

Triglyceride/glucose index is a reliable alternative marker for insulin resistance in South American overweight and obese children and adolescents.

Background The aim of the present study was to investigate the correlation between the triglyceride/glucose index (TyG index) and homeostasis model assessment of insulin resistance (HOMA-IR). Additionally, we compared the ability of the TyG index and triglycerides/high-density lipoprotein cholesterol (TG/HDL-c) index and the combination of these two indices (TyG index plus TG/HDL-c) to predict insulin resistance (IR) in South American overweight and obese children and adolescents. Methods A cross-sectional study was carried out in 345 overweight adolescents aged 10-18 years, from both the sexes. The TyG index was calculated as Ln (fasting triglycerides [mg/dL] × fasting glucose [mg/dL])/2, while the TG/HDL-c index was calculated by the division of TG (mg/dL) by HDL-c (mg/dL). HOMA-IR was calculated with the formula: fasting insulin (FI) (U/mL) × fasting glucose (mmol/L)/22.5. The cut-off point used to determine the presence of IR was HOMA-IR ≥ 3.16. Results The TyG index showed a positive correlation with HOMA-IR. The area under the receiver operating characteristic (ROC) curve of the TyG index was 0.74, indicating good sensitivity (75.7%) and specificity (67.4%). Furthermore, the TyG index cut-off point of >4.44 was established for IR prediction in this population. Conclusions The TyG index is a simple and cost-effective surrogate marker of IR in South American overweight children and adolescents. Moreover, due to its good accessibility, it can be used in large epidemiological studies.

Intestinal parasitosis and environmental contamination with helminths and protozoa in a Quilombola community of southeast Brazil / Parasitismo intestinal y contaminación ambiental con helmintos y protozoarios en una comunidad quilombola del sudeste de Brasil

Introduction: Intestinal parasitosis by helminths and protozoa is still today a global public health problem mainly affecting people living in conditions of social vulnerability, including rural communities. Objective: Describe human intestinal parasitosis and environmental contamination with helminths and protozoa in the Quilombola community of Quartel do Indaiá (of African descent) in the State of Minas Gerais, Brazil. Methods: A cross-sectional study was conducted of stool and soil samples by spontaneous sedimentation, and of plant samples by centrifugation sedimentation, to detect intestinal helminths and protozoa. Water samples were analyzed for total and fecal coliforms. Results: Helminths and protozoa were found in 45.5 percent of the people (n = 66). The species detected were Ascaris lumbricoides (18.2 percent), Entamoeba coli (18.2 percent), Endolimax nana (18.2 percent), ancylostoma (6.1 percent, Iodamoeba butschlii (4.6 percent), Giardia duodenalis (3 percent) and Trichuris trichiura (1.5 percent). More than one species were present in 19.7 percent of the samples. In 18 of the 39 sites sampled, the soil was contaminated with E. coli, E. nana, A. lumbricoides, I. butschlii and/or Enterobius vermicularis. Vegetables (n = 135) were contaminated in 75 samples with 7 of the 8 species analyzed. The contaminants were E. coli cysts, A. lumbricoides eggs and ancylostoma. All water samples were contaminated with total and fecal coliforms. Conclusions: The Quilombola community of Quartel do Indaiá had high levels of human infection and high environmental contamination with intestinal parasites or protozoa, probably due to lack of appropriate sanitary conditions. It is necessary to improve the access to treated water and sanitation(AU)

Introducción: El parasitismo intestinal por helmintos y protozoarios todavía es un problema de salud pública mundial, que afecta sobre todo personas en condiciones de vulnerabilidad social, incluso las comunidades rurales. Objectivo: Describir la infección humana y la contaminación ambiental por parásitos/comensales intestinales en una comunidade 'quilombola' Quartel do Indaiá (descendentes de esclavos) del Estado de Minas Gerais, Brasil. Métodos: Estudio de corte transversal con análisis de muestras fecales y de tierra por sedimentación espontánea, y de vegetales por sedimentación con centrifugación para detección de parásitos o comensales intestinales. Se analizaron muestras de agua para detección de coliformes totales y fecales. Resultados: Se observó la ocurrencia de parásitos o comensales en 45.5 por ciento de las personas (n = 66). Las especies detectadas fueron Ascaris lumbricoides (18,2 por ciento), Entamoeba coli (18,2 por ciento), Endolimax nana (18,2 por ciento), anquilostomas (6.1 por ciento), Iodamoeba butschlii (4,6 por ciento), Giardia duodenalis (3 por ciento), and Trichuris trichiura (1,5 por ciento). Para 19,7 por ciento de las muestras se detectaron más de una especie. El suelo estuvo contaminado en 18 de los 39 sitios muestreados, con presencia de E. coli, E. nana, A. lumbricoides, I. butschlii y/o Enterobius vermicularis. Los vegetales (n = 135) presentaron contaminación en 75 muestras de 7, entre 8 especies analizadas. Sus contaminantes fueron quistos de E. coli y huevos de A. lumbricoides y anquilostoma. Todas las muestras de agua estaban contaminadas por coliformes totales y fecales. Conclusiones: La comunidad 'quilombola' Quartel do Indaiá presentó alta infección humana y alta contaminación ambiental por parásitos o comensales intestinales, lo que se debe probablemente a la falta de condiciones sanitarias. Se necesita mejorar el acceso para agua tratada y estructuras de saneamiento(AU)

Multidisciplinary obesity treatment program improved health-related quality of life and positively correlated with anthropometric and body composition but not with cardiorespiratory fitness parameters in adolescents.

PURPOSE: The aim of the present study was to verify the effects of a 16-week multidisciplinary obesity treatment program (MOTP) on health-related quality of life (HRQoL) in adolescents with weight excess. In addition, we verified a possible association between changes on HRQoL and anthropometric, body composition, and cardiorespiratory fitness (CRF) parameters. METHODS: Two hundred four adolescents aged from 15 to 18 years were distributed in control group (CG) and intervention group (IG). They underwent a 16-week MOTP composed by nutritional, psychological, and health-related physical activity group sessions. Moreover, they performed physical exercise sessions three times per week during the whole 16-week program. Data on HRQoL, body composition, CRF and anthropometry were collected using standard protocols and validated questionnaires. RESULTS: The MOTP promoted significant enhancements in all HRQoL domains, except for the school domain in IG. Furthermore, positive correlations between HRQoL and body weight (BW), body fat (BF), waist circumference (WC), and body mass index (BMI) z-score were verified. Higher scores of HRQoL might be achieved by improving these variables. CONCLUSIONS: The 16-week MOTP was effective to improve HRQoL in adolescents with weight excess. This improvement has a positive correlation with enhancements in BW, BMI z-score, WC, and BF. Nevertheless, these findings have not reached a consensus on literature and still need to be further enlightened.

The prevalence of Active Play in Brazilian children and adolescents: a systematic review / Prevalência de Active Play em crianças e adolescentes brasileiros: uma revisão sistemática

Abstract A systematic review of the prevalence of Active Play in Brazilian children and adolescents was performed. Only fully available scientific papers that measured Active Play or leisure time physical activity independently from other types of physical activity in Brazilian children and/or adolescents were considered for inclusion. The search for potential articles was performed on the following electronic databases: Pubmed/Medline, Web of Science, Bireme, Scielo and Scopus. Initially, 63 papers met the eligibility criteria. However, after deeply analyzed, seven studies remained and were included in the present review. The overall prevalence of Active Play was 36%, in which varied from 27.2% to 79.3%. Boys presented a prevalence of 47%, ranging from 39,1% to 79.9%, while the prevalence in girls reached 26%, varying from 13.9% to 78.7%. Although the prevalence of Active Play in Brazil in not satisfactory, the potential to present a reliable data regarding this theme should be highlighted. In agreement with some other studies, boys presented a higher prevalence of physical activity than girls. Also, any socioeconomic pattern regarding the prevalence of Active Play in children and adolescents was observed when the results from this study were compared to other studies developed in other countries from several socioeconomic status. The Active Play should be further investigated individually, as a pivotal component of physical activity, as well as its impact on physical inactivity-related comorbidities.

Resumo Foi realizada Revisão sistemática acerca da prevalência de brincadeiras ativas em crianças e adolescentes brasileiros. Apenas trabalhos científicos totalmente disponíveis que mediram a atividade física praticada como brincadeira ou lazer em crianças e/ou adolescentes brasileiros foram considerados para inclusão. A busca por artigos foi realizada nas seguintes bases de dados eletrônicas: PubMed/Medline, Web of Science, Bireme, Scielo e Scopus. Inicialmente, 63 artigos preencheram os critérios de elegibilidade, e após análise minuciosa, sete estudos foram incluídos na presente revisão. A prevalência geral de brincadeiras ativas foi de 36%, variando de 27,2% a 79,3%. Os meninos apresentaram prevalência de 47%, variando de 39,1% a 79,9%, enquanto a prevalência nas meninas chegou a 26%, variando de 13,9% a78,7%. Embora no Brasil essa prevalência não seja satisfatória, destaca-se o potencial de apresentar dados relevantes sobre esta temática. Corroborando com outros estudos, os meninos apresentaram maior prevalência de atividade física como brincadeira ou lazer que as meninas. Além disso, não foi encontrado um padrão socioeconômico em relação à prevalência de brincadeiras ativas em crianças e adolescentes quando os resultados deste estudo foram comparados com outros estudos desenvolvidos em outros países de diferentes condições socioeconômicas. Portanto, brincadeiras ativas devem ser investigadas individualmente, como um componente essencial da atividade física, bem como seu impacto nas comorbidades relacionadas à inatividade física.

Application of high-resolution array platform for genome-wide copy number variation analysis in patients with nonsyndromic cleft lip and palate.

BACKGROUND: Although more than 14 loci may be involved in the development of nonsyndromic cleft lip and palate (NSCLP), the etiology has not been fully elucidated due to genetic and environmental risk factor interactions. Despite advances in identifying genes associated with the NSCLP development using traditional genetic mapping strategies of candidate genes, genome-wide studies, and epidemiologic and linkage analysis, microarray techniques have become important complementary tools in the search for potential causative oral clefts genes in genetic studies. Microarray hybridization enables scanning of the whole genome and detecting copy number variants (CNVs). Although common benign CNVs are often smaller, with sizes smaller than 20 kb, here we reveal small exonic CNVs based on the importance of the encompassed genes in cleft lip and palate phenotype. METHODS: Microarray hybridization analysis was performed in 15 individuals with NSCLP. RESULTS: We identified 11 exonic CNVs affecting at least one exon of the candidate genes. Thirteen candidate genes (COL11A1-1p21; IRF6-1q32.3; MSX1-4p16.2; TERT-5p15.33; MIR4457-5p15.33; CLPTM1L-5p15.33; ESR1-6q25.1; GLI3-7p13; FGFR-8p11.23; TBX1-22q11.21; OFD-Xp22; PHF8-Xp11.22; and FLNA-Xq28) overlapped with the CNVs identified. CONCLUSIONS: Considering the importance to NSCLP, the microdeletions that encompass MSX1, microduplications over TERT, MIR4457, CLPTM1L, and microduplication of PHF8 have been identified as small CNVs related to sequence variants associated with oral clefts susceptibility. Our findings represent a preliminary study on the clinical significance of small CNVs and their relationship with genes implicated in NSCLP.

Novel multidisciplinary approach to monitor and treat fetuses with gastroschisis using the Svetliza Reducibility Index and the EXIT-like procedure / Nova abordagem multidisciplinar para monitorizar e tratar fetos com gastrosquise utilizando o Svetliza Reducibility Index e o procedimento EXIT-like

ABSTRACT Objective: To describe our initial experience with a novel approach to follow-up and treat gastroschisis in "zero minute" using the EXITlike procedure. Methods: Eleven fetuses with prenatal diagnosis of gastroschisis were evaluated. The Svetliza Reductibility Index was used to prospectively evaluate five cases, and six cases were used as historical controls. The Svetliza Reductibility Index consisted in dividing the real abdominal wall defect diameter by the larger intestinal loop to be fitted in such space. The EXIT-like procedure consists in planned cesarean section, fetal analgesia and return of the herniated viscera to the abdominal cavity before the baby can fill the intestines with air. No general anesthesia or uterine relaxation is needed. Exteriorized viscera reduction is performed while umbilical cord circulation is maintained. Results: Four of the five cases were performed with the EXIT-like procedure. Successful complete closure was achieved in three infants. The other cases were planned deliveries at term and treated by construction of a Silo. The average time to return the viscera in EXIT-like Group was 5.0 minutes, and, in all cases, oximetry was maintained within normal ranges. In the perinatal period, there were significant statistical differences in ventilation days required (p = 0.0169), duration of parenteral nutrition (p=0.0104) and duration of enteral feed (p=0.0294). Conclusion: The Svetliza Reductibility Index and EXIT-like procedure could be new options to follow and treat gastroschisis, with significantly improved neonatal outcome in our unit. Further randomized studies are needed to evaluate this novel approach.

RESUMO Objetivo: Descrever a experiência inicial com a nova técnica cirúrgica EXIT-like para acompanhamento e correção de gastrosquise no "minuto zero". Métodos: Foram avaliados onze fetos com diagnóstico pré-natal de gastrosquise. O Svetliza Reducibility Index foi usado prospectivamente para avaliar cinco casos, e seis foram utilizados como controles. O índice foi calculado dividindo-se o diâmetro do defeito da parede abdominal pela maior alça intestinal que coubesse neste espaço. O procedimento EXIT-like compreendeu cesárea programada, analgesia fetal e redução da víscera herniada para a cavidade abdominal, antes da deglutição de ar pelo recém- nascido. Não são necessários anestesia geral e nem relaxamento uterino. A redução da víscera exteriorizada é realizada enquanto se mantém a circulação do cordão umbilical. Resultados: Quatro casos, dos cinco, foram submetidos ao EXIT-like. A correção foi completa em três casos. Os demais casos foram partos a termo planejados, e a correção do defeito foi feita com Silo. O tempo médio de redução da víscera foi de 5,0 minutos no grupo submetido ao procedimento EXITlike, e a oximetria foi mantida dentro dos valores de variação normal em todos os casos. No período perinatal, foram observadas diferenças estatisticamente significativas no tempo de ventilação mecânica (p=0,0169), duração da nutrição parenteral (p = 0,0104) e da nutrição enteral (p=0,0294). Conclusão: O Svetliza Reducibility Index e o procedimento EXIT-like podem ser novas opções para acompanhar e tratar gastroquise, com desfecho neonatal significativamente melhor em nossa unidade. Novos estudos randomizados são necessários para avaliar esta nova abordagem.
