Multicomponent obesity prevention intervention in low-income preschoolers: Primary and subgroup analyses of the NET-works randomized clinical trial, 2012-2017

Objectives. To evaluate a multicomponent obesity prevention intervention among diverse, low-income preschoolers. Methods. Parent-child dyads (n = 534) were randomized to the Now Everybody Together for Amazing and Healthful Kids (NET-Works) intervention or usual care in Minneapolis, MN (2012-2017). The intervention consisted of home visits, parenting classes, and telephone check-ins. The primary outcomes were adjusted 24- and 36-month body mass index (BMI). Results. Compared with usual care, the NET-Works intervention showed no significant difference in BMI change at 24 (-0.12 kg/m2; 95% confidence interval [CI] = -0.44, 0.19) or 36 months (-0.19 kg/m2; 95% CI = -0.64, 0.26). Energy intake was significantly lower in the NET-Works group at 24 (-90 kcal/day; 95% CI = -164, -16) and 36 months (-101 kcal/day; 95% CI = -164, -37). Television viewing was significantly lower in the NET-Works group at 24 (rate ratio = 0.84; 95% CI = 0.75, 0.93) and 36 months (rate ratio = 0.88; 95% CI = 0.78, 0.99). Children with baseline overweight or obesity had lower BMI in the NET-Works group than those in usual care at 36 months (-0.71 kg/m2; 95% CI = -1.30, -0.12). Hispanic children had lower BMI in the NET-Works group than those in usual care at 36 months (-0.59 kg/m2; 95% CI = -1.14, -0.04). Conclusions. In secondary analyses, NET-Works significantly reduced BMI over 3 years among Hispanic children and children with baseline overweight or obesity.

Applying the Behavior Change Technique Taxonomy to Four Multicomponent Childhood Obesity Interventions

Applying the Behavior Change Technique Taxonomy has the potential to facilitate identification of effective childhood obesity intervention components. This article evaluates the feasibility of coding Childhood Obesity Prevention and Treatment Consortium interventions and compares reliability between external taxonomy-familiar coders and internal intervention-familiar coders. After training, coder pairs independently coded prespecified portions of intervention materials. An adjudication process was used to explore coding discrepancies. Reliability between internal and external coders was moderate (prevalence and bias-adjusted kappa.38 to.55). Reliability for specific target behaviors varied with substantial agreement for physical activity (.63 to.76) and moderate for dietary intake (.44 to.63). Applying the taxonomy to these interventions was feasible, but agreement was modest. Coding discrepancies highlight the importance of refining coding to capture the complexities of childhood obesity interventions, which often engage multiple recipients (e.g., parents and/or children) and address multiple behaviors (e.g., diet, physical activity, screen time)

Phenotypic anchoring of arsenic and cadmium toxicity in three hepatic-related cell systems reveals compound- and cell-specific selective up-regulation of stress protein expression: implications for fingerprint profiling of cytotoxicity

Exposure of cells to toxic chemicals is known to up-regulate the expression of a number of stress proteins (SPs), including metallothionein (MT) and members of the heat shock protein (HSP) family, and this response may allow the development of a fingerprint profile to identify mechanisms of toxicity in an in vitro toxicology setting. To test this hypothesis, three hepatic-derived cell culture systems (rat hepatoma FGC4 cell line, rat hepatocytes, human hepatoma HepG2 cell line) were exposed to cadmium (as CdCl2) and arsenic (as NaAsO2), two compounds believed to exert their toxicity through an oxidative stress mechanism, under conditions of phenotypic anchoring defined as minimal and mild toxicity (approx. 5 and 25% reduction in neutral red uptake respectively). The expression of six SPs – MT, HSP25/27, HSP40, HSP60, HSP70, and HSP90 – was then determined by ELISA. Expression of four of these SPs – MT, HSP25/27, HSP40 and HSP70 – was up-regulated in at least one experimental condition. However, the patterns of expression of these four SPs varied across the experimental conditions, according to differences in toxicant concentration and/or level of toxicity, cell-type, and toxicant itself. This lack of uniformity in response of a focussed set of mechanistically-defensible targets suggests that similar problems may emerge when using more global approaches based on genomics and proteomics, in which problems of redundancy in targets and uncertain mechanistic relevance will be greater

Sub-regional Meeting on Disability Legislation: Decent Work for Persons with Disabilities in Asia, UN Conference Centre, Bangkok, Thailand, 23-24 June 2008

The Sub-regional Meeting on Disability Legislation, jointly organized by the ILO and the Office of the High Commissioner for Human Rights (OHCHR), took place in the framework of a technical cooperation project, “Promoting the Employability and Employment of Persons with Disabilities through Effective Legislation (PEPDEL)”, funded by the Government of Ireland. The meeting aimed to provide participants with an appropriate platform for discussion regarding the main legal issues in the field of employment discrimination law relating to disability and to sensitize them to key concepts in disability discrimination law and specifically the CRPD. Participants examined good practices in implementing disability discrimination legislation, with a view to facilitating the implementation of the CRPD in the Asian region. The meeting also provided participants with an opportunity for networking withlegal and other experts in Asia and beyond.New_30___Sub_regional_Meeting_on_Disability_Legislation_final_261_11_08.pdf: 268 downloads, before Oct. 1, 2020

Human cutaneous leishmaniasis caused by Leishmania (Viannia) braziliensis in Santiago del Estero, Argentina: identification of parasites by monoclonal antibodies and isoenzymes Leishmaniose cutânea humana causada por Leishmania (Viannia) braziliensis na Província de Santiago del Estero, Argentina: identificação dos parasitas por anticorpos monoclonais e isoenzimas

Diagnostic and parasite characterization and identification studies were carried out in human patients with cutaneous leishmaniasis lesions in Santiago del Estero, Northern Province of Argentina. Diagnostic procedures were biopsies of lesions for smears and inoculations in hamster, needle aspirations of material from ulcers for "in vitro" cultures. Immunodiagnostic techniques applied were IFAT-IgG and Montenegro skin test. Primary isolation of eight stocks of leishmanial parasites was achieved from patients with active lesions. All stocks were biologically characterized by their behaviour in hamster, measurements of amastigote and promastigotes and growth "in vitro". Eight stocks were characterized and identified at species level by their reactivity to a cross-panel of sub-genus and specie-specific Monoclonal Antibodies through an Indirect Immunofluorescence technique and a Dot-ELISA. We conclude from the serodeme analysis of Argentina stocks that: stocks MHOM/AR/92/SE-1; SE-2; SE-4; SE-8; SE-8-I; SE-30; SE-34 and SE-36 are Leishmania (Viannia) braziliensis. Three Leishmania stocks (SE-1; SE-2 and SE-30) did not react with one highly specie-specific Monoclonal Antibody (Clone: B-18, Leishmania (Viannia) braziliensis marker) disclosing two serodeme group patterns. Five out of eight soluble extracts of leishmanial promastigotes were electrophoresed on thin-layer starch gels and examined for the enzyme MPI, Mannose Phosphate Isomerase; MDH, Malate Dehydrogenase; 6PGD, 6 Phosphogluconate Dehydrogenase; NH, Nucleoside Hydrolase, 2-deoxyinosinc as substrate; SOD, Superoxide Dismutase; GPI, Glucose Phosphate Isomerase and ES, Esterase. From the isoenzyme studies we concluded that stocks: MHOM/AR/92/SE-1; SE-2; SE-4; SE-8 and SE-8-I are isoenzymatically Leishmania (Viannia) braziliensis. We need to analyze more enzymes before assigning them to a braziliensis zymodeme.<br>Estudos de diagnóstico, caracterização parasitária e identificação foram conduzidos em pacientes humanos com lesões cutâneas de leishmaniose na Província de Santiago del Estero, no Norte da Argentina. Os procedimentos de diagnóstico foram: biópsias de lesões para utilização em esfregaços e inoculação em hamster; aspiração (com agulha) de úlceras, para cultura "in vitro". As técnicas imunodiagnósticas empregadas foram a IFAT-IgG e o teste intradérmico de Montenegro. Oito cepas de parasitas foram isoladas, sendo estas obtidas de pacientes com lesões ativas. Todas as cepas foram inicialmente caracterizadas biologicamente por seu comportamento na infecção experimental do hamster, mensuração dos amastigotas e promastigotas e crescimento "in vitro". As mesmas oito cepas foram logo identificadas e caracterizadas a nível de espécie, devido a sua reatividade frente a um painel de anticorpos monoclonais subgênero e espécie-específicos. Isso foi realizado utilizando o teste de Imunofluorescência Indireta (IFAT/MAbs) e de um procedimento de Dot-ELISA. Nós concluímos a partir da análise de serodema dos isolados argentinos que: MHOM/AR/92/SE-1; SE-2; SE-4; SE-8; SE-8-I; SE-30; SE-34 e SE-36 são Leishmania (Viannia) braziliensis. Entretanto, três dos isolados de Leishmania (SE-1; SE-2 e SE-30) não foram reconhecidos quando testados com um anticorpo monoclonal de reconhecida alta espécie-especificidade (clone B-18, marcador consagrado de Leishmania (Viannia) braziliensis), revelando a existência de dois tipos de serodemas entre as cepas estudadas. Cinco dos oito extratos solúveis de Leishmania foram submetidos à eletroforese em gel de amido de camada fina e subseqüentemente examinadas a fim de constatar a atividade das enzimas MPI, MDH, 6PGD, NH, NH-D, SOD, GPI e ES. Fundamentados nos estudos dos corridos eletroforéticos obtidos nos ensaios isoenzimáticos chegamos à conclusão que as cepas MHOM/AR/92 SE-1; SE-2; SE-4; SE-8 e SE-8-I são Leishmania (Viannia) braziliensis. É necessário analisar mais enzimas antes de enquadrá-los nos zymodema braziliensi
