Prevalence of obesity among young Asian-American children

BACKGROUND: Asian-American children are considered to be at low risk of obesity, but previous estimates have not distinguished between children from different Asian countries. We estimate the prevalence of obesity among Asian-American children by mother\u27s country of origin, generational status, and family socioeconomic factors using a secondary analysis of the Early Childhood Longitudinal Study-Birth Cohort (ECLS-B) wave III (children ∼4 years old) dataset. METHODS: The ECLS-B is a nationally representative study of children born in 2001 that oversampled births to Asian mothers. Asian ethnic categories included Chinese, Japanese, Filipino, Asian Indian, Korean, Vietnamese, and Other Asian/Pacific Islander. The primary outcome variable was weight status; overweight = BMI ≥85(th) and obese = BMI ≥95(th) percentile for age and gender. RESULTS: Twenty-six percent [95% confidence interval (CI) 23.6-29.1] of Asian-American 4 year olds were overweight or obese, and 13% (95% CI 10.2-15.2) were obese. Chinese-American children were at lower risk of overweight or obesity (23.5%, 95% CI 18.4-29.5 ) compared to whites (36%, 95% CI 34.3-37.7); Asian-Indian 4 year olds had the lowest rates of overweight or obesity (15.6%, 95% CI 8.0-28.2) and were most likely to be underweight (10%, 95% CI 4.9-19.4). Among Asians,Vietnamese-American children had the highest rate of overweight or obesity (34.7%, 95% CI 0.6-52.3). CONCLUSIONS: Vietnamese-American children are at elevated risk of obesity and overweight, whereas Chinese and Asian-Indian children are at low risk. After controlling for Asian ethnicity, maternal education, and household poverty status, Asian-American children whose mothers were born outside the United States were less likely to be obese [odds ratio = 0.55 (0.32-0.95), p = 0.03]

Precision nomenclature for the new genomics

The confluence of two scientific disciplines may lead to nomenclature conflicts that require new terms while respecting historical definitions. This is the situation with the current state of cytology and genomics, which offer examples of distinct nomenclature and vocabularies that require reconciliation. In this article, we propose the new terms C-scaffold (for chromosome-scale assemblies of sequenced DNA fragments, commonly named scaffolds) and scaffotype (the resulting collection of C-scaffolds that represent an organism\u27s genome). This nomenclature avoids conflict with the historical definitions of the terms chromosome (a microscopic body made of DNA and protein) and karyotype (the collection of images of all chromosomes of an organism or species). As large-scale sequencing projects progress, adoption of this nomenclature will assist end users to properly classify genome assemblies, thus facilitating genomic analysis

The significance and expectations of HIV cure research among people living with HIV in Australia.

Most people living with HIV (PLHIV) with reliable access to antiretroviral treatment (ART) have a life expectancy similar to uninfected populations. Despite this, HIV can negatively affect their social and psychological wellbeing. This study aimed to enhance understanding of the expectations PLHIV hold for HIV cure research and the implications this has for HIV cure research trials. We interviewed 20 Australian PLHIV about their expectations for HIV cure research outcomes and the impact a potential cure for HIV may have on their everyday lives. Data were analysed thematically, using both inductive and deductive approaches. The significance of a cure for HIV was expressed by participants as something that would offer relief from their sense of vigilance or uncertainty about their health into the future. A cure was also defined in social terms, as alleviation from worry about potential for onward HIV transmission, concerns for friends and family, and the negative impact of HIV-related stigma. Participants did not consider sustained medication-free viral suppression (or remission) as a cure for HIV because this did not offer certainty in remaining virus free in a way that would alleviate these fears and concerns. A cure was seen as complete elimination of HIV from the body. There is an ethical need to consider the expectations of PLHIV in design of, and recruitment for, HIV cure-related research. The language used to describe HIV cure research should differentiate the long-term aspiration of achieving complete elimination of HIV from the body and possible shorter-term therapeutic advances, such as achieving medication free viral suppression

Genetic diversification of persistent Mycobacterium abscessus within cystic fibrosis patients

Mycobacterium (M.) abscessus infections in Cystic Fibrosis (CF) patients cause a deterioration of lung function. Treatment of these multidrug-resistant pathogens is associated with severe side-effects, while frequently unsuccessful. Insight on M. abscessus genomic evolvement during chronic lung infection would be beneficial for improving treatment strategies. A longitudinal study enrolling 42 CF patients was performed at a CF center in Berlin, Germany, to elaborate phylogeny and genomic diversification of in-patient M. abscessus. Eleven of the 42 CF patients were infected with M. abscessus. Five of these 11 patients were infected with global human-transmissible M. abscessus cluster strains. Phylogenetic analysis of 88 genomes from isolates of the 11 patients excluded occurrence of M. abscessus transmission among members of the study group. Genome sequencing and variant analysis of 30 isolates from 11 serial respiratory samples collected over 4.5 years from a chronically infected patient demonstrated accumulation of gene mutations. In total, 53 genes exhibiting non-synonymous variations were identified. Enrichment analysis emphasized genes involved in synthesis of glycopeptidolipids, genes from the embABC (arabinosyltransferase) operon, betA (glucose-methanol-choline oxidoreductase) and choD (cholesterol oxidase). Genetic diversity evolved in a variety of virulence- and resistance-associated genes. The strategy of M. abscessus populations in chronic lung infection is not clonal expansion of dominant variants, but to sustain simultaneously a wide range of genetic variants facilitating adaptation of the population to changing living conditions in the lung. Genomic diversification during chronic infection requires increased attention when new control strategies against M. abscessus infections are explored.Peer Reviewe

Narrative Processes Coding System: A Dialectical Constructivist Approach to Assessing Client Change Processes in Emotion-Focused Therapy of Depression

Drawing on a Dialectical Constructivist model of therapeutic change, this paper addresses the fundamental contributions of client narrative disclosure, emotional differentiation and reflexive meaning-making processes in emotion-focused treatments of depression. An overview of the multi-methodological steps undertaken to empirically investigate the contributions of client storytelling, emotional differentiation, and meaning-making processes, using the Narrative Processes Coding System (NPCS; Angus et al., 1999) are provided, followed by a summary of key research findings that informed the development of a narrative-informed approach to emotion-focused therapy of depression (Angus & Greenberg, 2011). Finally, therapy practice implications for the adoption of a research-informed approach to working with narrative and emotion processes in emotion-focused therapy are described and future research directions discussed

Multidrug Resistance of Escherichia coli From Outpatient Uncomplicated Urinary Tract Infections in a Large United States Integrated Healthcare Organization

Background Urinary tract infections (UTIs) cause significant disease and economic burden. Uncomplicated UTIs (uUTIs) occur in otherwise healthy individuals without underlying structural abnormalities, with uropathogenic Escherichia coli (UPEC) accounting for 80% of cases. With recent transitions in healthcare toward virtual visits, data on multidrug resistance (MDR) (resistant to ≥3 antibiotic classes) by care setting are needed to inform empiric treatment decision making. Methods We evaluated UPEC resistance over time by care setting (in-person vs virtual), in adults who received outpatient care for uUTI at Kaiser Permanente Southern California between January 2016 and December 2021. Results We included 174 185 individuals who had ≥1 UPEC uUTI (233 974 isolates) (92% female, 46% Hispanic, mean age 52 years [standard deviation 20]). Overall, prevalence of UPEC MDR decreased during the study period (13% to 12%) both in virtual and in-person settings (P for trendConclusions We observed a slight decrease in both class-specific antimicrobial resistance and MDR of UPEC overall, most commonly involving penicillins and TMP-SMX. Resistance patterns were consistent over time and similar in both in-person and virtual settings. Virtual healthcare may expand access to UTI care

Factors Associated with Elevated ALT in an International HIV/HBV Co-Infected Cohort on Long-Term HAART

Previous studies have demonstrated that hepatitis B virus (HBV) infection increases the risk for ALT elevations in HIV-HBV co-infected patients during the first year of HAART; however, there is limited data on the prevalence of ALT elevations with prolonged HAART in this patient group.To identify factors associated with ALT elevations in an HIV-HBV co-infected cohort receiving prolonged HAART, data from 143 co-infected patients on HAART enrolled in an international HIV-HBV co-infected cohort where ALT measurements were obtained every 6 months was analysed. A person-visit analysis was used to determine frequency of ALT elevation (≥ 2.5×ULN) at each visit. Factors associated with ALT elevation were determined using multivariate logistic regression with generalized estimating equations to account for correlated data. The median time on HAART at the end of follow-up was 5.6 years (range 0.4-13.3) years. During follow-up, median ALT was 36 U/L with 10.6% of person-visits classified as having ALT elevation. Most ALT elevations were grade 2 (86.5%), with only 13.5% of all ALT elevations grade 3 or higher. Univariate associations with ALT elevation (p<0.05) included history of AIDS, HBV DNA ≥ 2,000 IU/ml, HBeAg positive, study visit CD4 <200 cells/ml and nadir CD4 <200 cells/ml. In the multivariate analysis, only study visit CD4 <200 cells/ml (OR 2.07, 95%CI 1.04-4.11, p = 0.04) and HBeAg positive status (OR 2.22, 95%CI 1.03-4.79, p = 0.04) were independently associated with ALT elevation.In this HIV-HBV co-infected cohort, elevated ALT after >1 year of HAART was uncommon, and severe ALT elevations were rare. HIV-HBV co-infected patients on long-term HAART who are either HBeAg positive or have a CD4 count of <200 cells/ml are at increased risk for ALT elevations

Pathogenicity and immunogenicity of attenuated, nef-deleted HIV-1 strains in vivo

In efforts to develop an effective vaccine, sterilizing immunity to primate lentiviruses has only been achieved by the use of live attenuated viruses carrying major deletions in nef and other accessory genes. Although live attenuated HIV vaccines are unlikely to be developed due to a myriad of safety concerns, opportunities exist to better understand the correlates of immune protection against HIV infection by studying rare cohorts of long-term survivors infected with attenuated, nef-deleted HIV strains such as the Sydney blood bank cohort (SBBC). Here, we review studies of viral evolution, pathogenicity, and immune responses to HIV infection in SBBC members. The studies show that potent, broadly neutralizing anti-HIV antibodies and robust CD8+ T-cell responses to HIV infection were not necessary for long-term control of HIV infection in a subset of SBBC members, and were not sufficient to prevent HIV sequence evolution, augmentation of pathogenicity and eventual progression of HIV infection in another subset. However, a persistent T-helper proliferative response to HIV p24 antigen was associated with long-term control of infection. Together, these results underscore the importance of the host in the eventual outcome of infection. Thus, whilst generating an effective antibody and CD8+ T-cell response are an essential component of vaccines aimed at preventing primary HIV infection, T-helper responses may be important in the generation of an effective therapeutic vaccine aimed at blunting chronic HIV infection
