The H. pylori seropositivity rate of GI referral children with symptoms of abdominal pain was significantly higher. H. pylori infection in early childhood was found to be associated primarily with the child's household size and socioeconomic status.
Background: Childhood and adolescent obesity constitute a significant public health concern. Family health care settings with multidisciplinary teams provide an opportunity for weight loss treatment. The objective of this study was to examine the effect of intensive treatment designed to reduce weight using a parent-child lifestyle modification intervention in a family health care clinic for obese and overweight children who had failed previous treatment attempts.Methods: This was a practice-based 6-month intervention at Maccabi Health Care Services, an Israeli health maintenance organization, consisting of parental education, individual child consultation, and physical activity classes. We included in the intervention 100 obese or overweight children aged 5 to 14 years and their parents and 943 comparison children and their parents. Changes in body mass index z-scores, adjusted for socioeconomic status, were analyzed, with a follow-up at 14 months and a delayed follow-up at an average of 46.7 months.Results: The mean z-score after the intervention was lower in the intervention group compared to the comparison group (1.74 and 1.95, respectively; P ؍ .019). The intervention group sustained the reduction in z-score after an average of 46.7 months (P < .001). Of the overweight or obese children, 13% became normal weight after the intervention, compared with 4% of the comparison children.
The association of GB virus type C (GBV-C) virus and clinical disease is uncertain. The role of GBV-C and (Envelope) E2 antibody in children with liver transplants has not been determined. This study's aim is to examine the prevalence of GBV-C in children with liver transplants, to assess the relationship of GBV-C to posttransplant hepatitis, and to determine the role of E2 antibodies. Sera from 34 children, preliver and postliver transplant, between 1989-1996 were tested for GBV-C (Ribonucleic acid) RNA by the automated Abbott LCx PCR assay. Anti-E2 antibodies were detected by an Abbott immunoassay. Recent posttransplant liver biopsies were examined for hepatitis. The results of the study determined that pretransplant, four children (12%) were GBV-C RNA positive. Posttransplant, 14 (42%) children were GBV-C RNA positive. The GBV-C RNA positive conversion rate was 33% (CI 17.2-55.7%). Patients received blood products from a mean of 68 +/- 34 donors, which correlated with GBV-C acquisition. There was no difference in the incidence (32%versus 36%; p = 0.726) or severity (grade 2.00 versus 0.68; p = 0.126) of posttransplant hepatitis in the liver biopsies of GBV-C RNA negative and/or positive children, respectively. Pretransplant, nine of 32 children were anti-E2 positive. Posttransplant, eight of 32 children were anti-E2 positive, including five children who were anti-E2 positive pretransplant. Of nine children who were anti-E2 positive and GBV-C RNA negative pretransplant, three became GBV-C RNA positive posttransplant. The results of this study conclude that the prevalence of GBV-C infection in children postliver transplantation is high and that blood product transfusions correlate with GBV-C acquisition. Also, no correlation was found between GBV-C RNA and the incidence or severity of posttransplant hepatitis. Finally, E2 antibody presence before transplantation failed to provide complete protection from GBV-C acquisition.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
