 Objective:Objectives of this study were to examine the prospective association of childhood body mass index (BMI) and overweight and pubertal stages with BMI and overweight in early adulthood independent of each other.Design:A population-based prospective birth cohort.Subjects:We used a population-based prospective birth cohort of 2897 (52% men) young adults who were born during 1981-1983 in Brisbane, Australia, and for whom we had puberty stages using Tanner scale at 14 years and measured BMI at 5 years of age.Main outcome measures:Pubertal stages at adolescent and BMI and its categories at 21 years.Results:We found that increasing BMI and overweight at 5 years of age predict the advanced stages of puberty. An advanced stage of puberty predicts young adults` BMI and overweight status at 21 years. When taking both childhood BMI and pubertal status into consideration, we found that being overweight at 5 years substantively increases BMI at 21 years, regardless of the stage of puberty reported at 14 years. We also found that subjects with normal BMI at 5 years but with higher stages of puberty at 14 years had threefolds greater risk to be overweight at 21 years compared with their counterparts. All associations remained consistent after controlling for potential confounders.Conclusions:Although this study underscores the impact of both child overweight and pubertal development on young adults` obesity, the mechanism that further explainsthe impact of puberty needs to be identified.International Journal of Obesity advance online publication, 4 November 2008; doi:10.1038/ijo.2008.220.

 OBJECTIVE: The present review examines efficacious psycho-behavioral interventions in preventing weight gains or reducing weight among US multiethnic and minority adults as few studies were conducted to review such interventions to date. METHODS: Data were examined from 24 controlled intervention studies, representing 23 programs and involving 13,326 adults. Studies were identified through manual and online search of databases that include MEDLINE, Academic Search Premier, ERIC, PsycARTICLES, SPORTDiscus, and CINAHL Plus. RESULTS: Whereas one-component (n=5, d=0.08, 90% CI=-0.04, 0.35) and two-component interventions (n=13, d=0.22, 90% CI=0.05, 0.40) showed a low mean effect size, three-component interventions (n=6, d=0.52, 90% CI=0.39, 0.65) showed a moderate effect size. Interventions conducted in individual sessions (n=15, d=0.40, 90% CI=0.24, 0.56) showed a higher mean effect size than group interventions (n=9, d=0.08, 90% CI=-0.04, 0.30) although the confidence intervals overlapped. CONCLUSIONS: The study results indicate that future obesity prevention interventions targeting multiethnic and minority adults might benefit from incorporating individual sessions, family involvement, and problem solving strategies into multi-component programs that focus on lifestyle changes.

Abstract: [click here to display abstract text]
 OBJECTIVE: The Centers for Disease Control and Prevention recommends that HIV testing be a standard part of medical care; however, testing is voluntary and some patients decline. We evaluated 2 brief interventions to promote rapid HIV testing among STD clinic patients who initially declined testing. METHOD: Using a randomized controlled trial, patients either viewed an educational digital video disc (DVD) or participated in stage-based behavioral counseling (SBC) provided by a nurse. Sixty clients presenting for care at a STD clinic who initially declined HIV testing at registration and during risk behavior screening participated in the study. RESULTS: The primary outcome was whether patients agreed to be tested for HIV. The secondary outcomes included attitudes, knowledge, and stage-of-change regarding HIV testing. Patients receiving both interventions improved their attitudes and knowledge about testing (ps < .01). Patients receiving SBC agreed to testing more often (45%) than did patients who viewed the DVD (19%; p < .05). CONCLUSIONS: Brief interventions can increase rapid HIV testing acceptance among patients who are reluctant to be tested; counseling guided by behavioral science theory is more effective than a well-designed information-based intervention.

 OBJECTIVE: We wished to compare the sensitivity of an enzyme-linked immunospot assay (T-SPOT.TB; Oxford Immunotec, Oxford, United Kingdom) and the tuberculin skin test for the detection of tuberculosis infection in very young children being evaluated for active tuberculosis in a rural community setting. METHODS: Children with a history of exposure to tuberculosis and children presenting to a local clinic or hospital with symptoms suggesting tuberculosis were admitted to a dedicated case verification ward. T-SPOT.TB testing was performed, and children were evaluated with a clinical examination, a tuberculin skin test, chest radiographs, and cultures of induced sputum and gastric lavage specimens. The diagnosis was determined by using a clinical algorithm. RESULTS: A total of 243 children (median age: 18 months) were recruited, of whom 214 (88%) had interpretable T-SPOT.TB results. Children > or =12 months of age were more likely than younger children to have positive T-SPOT.TB results, whereas tuberculin skin test results were unaffected by age. The sensitivity of the T-SPOT.TB was no better than that of the tuberculin skin test for culture-confirmed tuberculosis (50% and 80%, respectively) and was poorer for the combined group of culture-confirmed and clinically probable tuberculosis (40% and 52%, respectively). For the 50 children clinically categorized as not having tuberculosis, the specificity of both the T-SPOT.TB and the tuberculin skin test was 84%. CONCLUSIONS: For young children presenting in a community setting after exposure to tuberculosis or with symptoms suggesting tuberculosis, T-SPOT.TB cannot be used to exclude active disease. The sensitivity of this assay may be impaired for very young children.

Abstract: [click here to display abstract text]
 OBJECTIVES: To systematically review the effectiveness and cost-effectiveness of palivizumab for the prevention of respiratory syncytial virus (RSV) in children and examine prognostic factors to determine whether subgroups can be identified with important differences in cost-effectiveness. DATA SOURCES: Bibliographic databases were searched from inception to March 2007 for literature on the effectiveness and cost-effectiveness of prophylaxis with palivizumab. REVIEW METHODS: The literature was systematically reviewed and current economic evaluations were analysed to identify which parameters were driving the different cost-effectiveness estimates. A probabilistic decision-analytical model was built to assess the cost-effectiveness of prophylaxis with palivizumab for children at risk of RSV infection and the parameters populated with the best estimates thought most applicable to the UK. We also constructed a new model, the Birmingham Economic Evaluation (BrumEE). Cost-effectiveness analyses were undertaken from both NHS and societal perspectives. RESULTS: Two randomised controlled trials (RCTs) were identified. Prophylaxis with palivizumab for preterm infants without chronic lung disease (CLD) or children with CLD resulted in a 55% reduction in RSV hospital admission: 4.8% (48/1002) in the palivizumab group and 10.6% (53/500) in the no prophylaxis group (p = 0.0004). Prophylaxis with palivizumab was associated with a 45% reduction in hospitalisation rate RSV among children with coronary heart disease (CHD). Hospitalisation rates for RSV were 5.3% (34/639) in the palivizumab group and 9.7% (63/648) in the no prophylaxis group (p = 0.003). Of existing economic evaluations, 3 systematic reviews and 18 primary studies were identified. All the systematic reviews concluded that the potential costs of palivizumab were far in excess of any potential savings achieved by decreasing hospital admission rates, and that the use of palivizumab was unlikely to be cost-effective in all children for whom it is recommended, but that its continued use for particularly high-risk children may be justified. The incremental cost-effectiveness ratios (ICERs) of the primary studies varied 17-fold for life-years gained (LYG), from 25,800 pounds/LYG to 404,900 pounds/LYG, and several hundred-fold for quality-adjusted life-years (QALYs), from 3200 pounds/QALY to 1,489,700 pounds/QALY for preterm infants without CLD or children with CLD. For children with CHD, the ICER varied from 5300 pounds/LYG to 7900 pounds/LYG and from 7500 pounds/QALY to 68,700 pounds/QALY. An analysis of what led to the discrepant ICERs showed that the assumed mortality rate for RSV infection was the most important driver. The results of the BrumEE confirm that palivizumab does not reach conventional levels of cost-effectiveness in any of the licensed indications if used for all eligible children. CONCLUSIONS: Prophylaxis with palivizumab is clinically effective for the reducing the risk of serious lower respiratory tract infection caused by RSV infection and requiring hospitalisation in high-risk children, but if used unselectively in the licensed population, the ICER is double that considered to represent good value for money in the UK. The BrumEE shows that prophylaxis with palivizumab may be cost-effective (based on a threshold of 30,000 pounds/QALY) for children with CLD when the children have two or more additional risk factors. Future research should initially focus on reviewing systematically the major uncertainties for patient subgroups with CLD and CHD and then on primary research to address the important uncertainties that remain.

Abstract: [click here to display abstract text]
 OBJECTIVE: Vitamin D insufficiency occurs commonly in HIV-infected youth in the United States. In light of the importance of vitamin D for skeletal and nonskeletal health, including innate immunity, developing methods for improving vitamin D status in HIV-infected children and adolescents is an important area of clinical research. The objective of this study was to evaluate the effect of administration of oral cholecalciferol, 100,000 IU every 2 months, and 1 g/day calcium on serum 25-hydroxyvitamin D concentrations, serum and urine calcium, and HIV disease progression during a 12-month period. METHODS: HIV-infected children and adolescents who were aged 6 to 16 years were randomly assigned to receive vitamin D (100,000 IU bimonthly) and calcium (1 g/day; n = 29) or double placebo (n = 27). Serum 25-hydroxyvitamin D concentrations as measured by radioimmunoassay, albumin-corrected calcium concentrations, and spot urinary calcium-creatinine ratios were determined monthly. RESULTS: No abnormalities in serum calcium concentration were observed. One participant who received placebo developed hypercalciuria. No group differences were seen in the change in CD4 count or CD4% or viral load during 12 months. The overall mean monthly serum 25-hydroxyvitamin D concentrations were higher in the group that received vitamin D and calcium than in the placebo group, as was the monthly serum 25-hydroxyvitamin D area under the curve. After completing 12 months of study, 2 (6.7%) participants in the group that received vitamin D and calcium had a trough serum 25-hydroxyvitamin D concentration <20 ng/mL compared with 14 (50%) in the placebo group. Twelve (44.4%) in the group that received vitamin D and calcium had a trough serum 25-hydroxyvitamin D concentration of > or =30 ng/mL compared with 3 (11.1%) in the placebo group. CONCLUSIONS: Administration of oral cholecalciferol to HIV-infected children and adolescents at a dosage of 100,000 IU every 2 months, together with 1 g/day calcium, is safe and results in significant increases in serum 25-hydroxyvitamin D concentrations.

Abstract: [click here to display abstract text]
 To determine whether lower levels of hepatitis C virus (HCV)-specific neutralizing antibodies (nAb) are associated with an increased risk of mother-to-child transmission (MTCT) of HCV, HCV nAb titers were assessed in 63 mothers coinfected with HCV and human immunodeficiency virus (HIV) type 1. Of the mothers, 16 transmitted HCV to their infant, but no difference was detected between the ability of maternal plasma from transmitters and nontransmitters to neutralize heterologous HCV pseudoparticles (median nAb titer, 1:125 vs. 1:100; P = .23). In the setting of HIV/HCV coinfection, we found no evidence that HCV nAbs are associated with the prevention of MTCT of HCV.

 A randomized cross-over trial of herpes simplex virus type 2 (HSV-2)-suppressive therapy (valacyclovir, 500 mg twice daily, or placebo for 8 weeks, a 2-week washout period, then the alternative therapy for 8 weeks) was conducted among 20 Peruvian women coinfected with HSV-2 and human immunodeficiency virus type 1 (HIV-1) who were not on antiretroviral therapy. Plasma samples (obtained weekly) and endocervical swab specimens (obtained thrice weekly) were collected for HIV-1 RNA polymerase chain reaction. Plasma HIV-1 level was significantly lower during the valacyclovir arm, compared with the placebo arm (-0.26 log(10) copies/mL, a 45% decrease [[Formula: see text]]), as was cervical HIV-1 level (-0.35 log(10) copies/swab, a 55% decrease [[Formula: see text]]). Suppressive HSV-2 therapy has the potential to reduce HIV-1 infectiousness and slow HIV-1 disease progression. Trial registration. @nbsp; ClinicalTrials.gov identifier: NCT00465205 .

 OBJECTIVE: The purpose of this study was to explore the association of metabolic syndrome and each of its components with all-cause and cardiovascular mortality in a general Italian elderly population. RESEARCH DESIGN AND METHODS: Metabolic syndrome, diagnosed by National Cholesterol Education Program Adult Treatment Panel III criteria, all-cause mortality, and cardiovascular mortality, was evaluated in 2,910 subjects aged > or =65 years of the Progetto Veneto Anziani (Pro.V.A.) Study during a mean follow-up time of 4.4 years. RESULTS: After multivariable adjustment, metabolic syndrome was associated with increased all-cause mortality in all subjects (hazard ratio 1.41 [95% CI 1.16-1.72], P = 0.001), among men (1.42 [1.06-1.89], P = 0.017), and among women (1.47 [1.13-1.91], P = 0.004). High glucose in all subjects (1.27 [1.02-1.59], P = 0.037) and in women (1.61 [1.16-2.24], P = 0.005) and low HDL cholesterol in women (1.48 [1.08-2.02], P = 0.014) were predictors of all-cause mortality, even independently of the interactions of different metabolic syndrome components. After multivariable adjustment, metabolic syndrome was also associated with increased cardiovascular mortality in all subjects (1.60 [1.17-2.19], P = 0.003), among men (1.66 [1.00-2.76], P = 0.051), and among women (1.60 [1.06-2.33], P = 0.025). High glucose (2.17 [1.28-3.68], P = 0.004) and low HDL cholesterol (1.78 [1.07-2.95], P = 0.026) among women predicted higher cardiovascular mortality. CONCLUSIONS: In this general Italian elderly population, among metabolic syndrome components, all-cause mortality is better predicted by high glucose in all subjects and in women and by low HDL cholesterol in women, whereas cardiovascular mortality is better predicted by high glucose and low HDL cholesterol in women.

Abstract: [click here to display abstract text]
 OBJECTIVES: Parenting is recognized as a key mediator in both health and educational outcomes. Much is known on the value of support and group work in benefiting parenting, but little is known on the effect of written information. A randomized, controlled trial was conducted to evaluate the effect of a parenting newsletter, sent monthly to the parents` home from birth to 1 year, on maternal well-being and parenting style. We tested the hypothesis that mothers receiving the newsletter would show less stress and better parenting characteristics than controls. METHODS: Parents of first infants born in a North East England District General Hospital between February and October 2003 who consented to take part in the study were randomly allocated to either the intervention or control arm. Those in the intervention arm were sent 12 monthly issues of an age-paced parenting newsletter containing information on emotional development, parent-child interaction, and play. Both the intervention and control group received normal parenting support. Mothers in both groups completed the Well-being Index, Parenting Daily Hassles Scale, and the Adult-Adolescent Parenting Inventory at birth and at 1 year. RESULTS: One hundred eighty-five mothers were recruited, with 94 randomly assigned to the intervention group, and 91 controls. Allowing for differences at recruitment, there were significant differences between the groups at 1 year: the intervention mothers had lower frequency and intensity of perceived hassles and fewer inappropriate expectations of the infant on the Adult-Adolescent Parenting Inventory than the control mothers. CONCLUSIONS: A monthly parenting newsletter sent directly to the home in the first year of life seems to help parents to understand their infant better and feel less hassled. This intervention is low cost and can be applied to all parents, so it is nonstigmatizing.
