High Potency and Other Alcoholic Beverage Consumption Among Adolescents

This study examined the prevalence of high potency (liquor, malt liquor, fortified wine) and other alcoholic beverage consumption (beer, wine/wine coolers) among adolescents, the impact of gender and ethnicity, and the risk and protective factors that predicted consumption. A confidential survey revealed that, among eighth grade students, wine/wine coolers were the most popular alcoholic beverages, with the highest levels of lifetime use, and the greatest current frequency and quantity of use, followed closely by beer and liquor. Minor gender differences were found, as well as notable ethnic differences, in consumption. Intentions and attitudes were important predictors of use across beverages. Different factors may need to be targeted depending upon the type of beverage that is addressed in future prevention programs

Promoting the Health of Parents & Children: Addressing Perinatal Mental Health by Building Medical Provider Capacity Through Perinatal Psychiatry Access Programs

Mental health conditions are the most common obstetric complications of the perinatal period, impacting 1 in 5 individuals during pregnancy and the year following pregnancy. Perinatal mental health (PMH) conditions have deleterious effects on the health of perinatal individuals and their children, and are a leading and preventable cause of maternal mortality. Nevertheless, PMH conditions are underrecognized, underdiagnosed, and undertreated. To address these gaps, Massachusetts created the Massachusetts Child Psychiatry Access Program (MCPAP) for Moms to build the capacity of frontline medical providers to address PMH conditions by providing education, consultation, and resources and referrals. MCPAP for Moms has emerged as a successful and scalable model with at least 25 states or organizations implementing or developing similar Perinatal Psychiatry Access Programs. This report summarizes the Perinatal Psychiatry Access Program model and its individual and national impact

Barriers to Hepatitis C Antiviral Therapy in HIV/HCV Co-Infected Patients in the United States: A Review

This review synthesized the literature for barriers to HCV antiviral treatment in persons with HIV/HCV co-infection. Searches of PubMed, Embase, CINAHL, and Web of Science were conducted to identify relevant articles. Articles were excluded based on the following criteria: study conducted outside of the United States, not original research, pediatric study population, experimental study design, non-HIV or non-HCV study population, and article published in a language other than English. Sixteen studies met criteria and varied widely in terms of study setting and design. Hepatic decompensation was the most commonly documented absolute/nonmodifiable medical barrier. Substance use was widely reported as a relative/modifiable medical barrier. Patient-level barriers included nonadherence to medical care, refusal of therapy, and social circumstances. Provider-level barriers included provider inexperience with antiviral treatment and/or reluctance of providers to refer patients for treatment. There are many ongoing challenges that are unique to managing this patient population effectively. Documenting and evaluating these obstacles are critical steps to managing and caring for these individuals in the future. In order to improve uptake of HCV therapy in persons with HIV/HCV co-infection, it is essential that barriers, both new and ongoing, are addressed, otherwise, treatment is of little benefit

Development of the Teacher Efficacy Toward Providing Physical Activity in the Classroom Scale

The overall aim for this study was to create and validate an instrument that helps researchers measure and better understand classroom teachers’ efficacy toward providing physical activity throughout the school day. The development of the Teacher Efficacy Toward Providing Physical Activity in the Classroom Scale (TETPPACS) occurred in two phases. First, in study one, after item development and face validity review, an exploratory factor analysis was conducted with pilot data (N = 320) to discover the factor structure of the TETPPACS. Second, with a follow-up sample (N = 192), a confirmatory factor analysis (CFA) was performed to confirm the factor structure and measurement quality of the instrument. The final bi-factor model with three efficacy-specific constructs and the general efficacy construct resulted in an acceptable fitting two-group configural model across elementary and high school teachers ( =363.791; CFI=.91; TLI=.87; SRMR=.066; RMSEA=.081). The results of this study suggest the new TETPPACS is a valid and reliable instrument to measure classroom teacher’s efficacy toward providing physical activity during the school day. This instrument can help researchers further investigate how teacher efficacy relates to implementation and facilitation of physical activity experiences throughout the school day

A global charter for the public\u27s health - The public\u27s health: the role, functions, competencies, education

Political leaders increasingly perceive health as being crucial to achieving growth, development, equity and stability throughout the world. Health is now understood as a product of complex and dynamic relations generated by numerous determinants at different levels of governance. Governments need to take into account the impact of social, environmental and behavioural health determinants, including economic constraints, living conditions, demographic changes and unhealthy lifestyles in many of the World Health Organization (WHO) Member States. This understanding and increasing globalization means it is very timely to review the role of (global) public health in this changing societal and political environment

A Novel Microfluidic Dielectrophoresis Technology to Enable Rapid Diagnosis of Mycobacteria tuberculosis in Clinical Samples

To achieve the global efforts to end tuberculosis, affordable diagnostics suitable for true point-of-care implementation are required to reach the missing millions. In addition, diagnostics with increased sensitivity and expanded drug susceptibility testing are needed to address drug resistance and to diagnose low-bacterial burden cases. The laboratory-on-a-chip technology described herein used dielectrophoresis to selectively isolate Mycobacterium tuberculosis from sputum samples, purifying the bacterial population ahead of molecular confirmation by multiplex real-time quantitative PCR. After optimization using a panel of 50 characterized sputum samples, the performance of the prototype was assessed against the current gold standards, screening 100 blinded sputum samples using characterized and biobanked sputum provided by Foundation for Innovative New Diagnostics. Concordance with culture diagnosis was 100% for smear-negative samples and 87% for smear-positive samples. Of the smear-positive samples, the high burden sample concordance was 100%. Samples were diagnosed on the basis of visual assessment of the dielectrophoresis array and by multiplex real-time quantitative PCR assay. The results described herein demonstrate the potential of the CAPTURE-XT technology to provide a powerful sample preparation tool that could function as a front-end platform for molecular detection. This versatile tool could equally be applied as a visual detection diagnostic, potentially associated with bacterial identification for low-cost screening or coupled with an expanded PCR assay for genotypic drug susceptibility testing

National trends in hospitalization and mortality rates for patients with HIV, HCV, or HIV/HCV coinfection from 1996–2010 in the United States: a cross-sectional study

Abstract Background The comparative impact of chronic viral monoinfection versus coinfection on inpatient outcomes and health care utilization is relatively unknown. This study examined trends, inpatient utilization, and hospital outcomes for patients with HIV, HCV, or HIV/HCV coinfection. Methods Data were from the 1996–2010 National Hospital Discharge Surveys. Hospitalizations with primary ICD-9-CM codes for HIV or HCV were included for HIV and HCV monoinfection, respectfully. Coinfection included both HIV and HCV codes. Demographic characteristics, select comorbidities, procedural interventions, average hospital length of stay (LOS), and discharge status were compared by infection status (HIV, HCV, HIV/HCV). Annual disease estimates and survey weights were used to generate hospitalization rates. Results ~6.6 million hospitalizations occurred in patients with HIV (39%), HCV (56%), or HIV/HCV (5%). The hospitalization rate (hospitalizations per 100 persons with infection) decreased in the HIV group (29.8 in 1996; 5.3 in 2010), decreased in the HIV/HCV group (2.0 in 1996; 1.5 in 2010), yet increased in the HCV group (0.2 in 1996; 0.9 in 2010). Median LOS from 1996 to 2010 (days, interquartile range) decreased in all groups: HIV, 6 (3–10) to 4 (3–8); HCV, 5 (3–9) to 4 (2–6); HIV/HCV, 6 (4–11) to 4 (2–7). Age-adjusted mortality rates decreased for all three groups. The rate of decline was least pronounced for those with HCV monoinfection. Conclusion Hospitalizations have declined more rapidly for patients with HIV infection (including HIV/HCV coinfection) than for patients with HCV infection. This growing disparity between HIV and HCV underscores the need to allocate more resources to HCV care in hopes that similar large-scale improvements can also be accomplished for patients with HCV

Gaping behaviour of Blue mussels (Mytilus edulis) in relation to freshwater runoff risks

Shellfish grown for food are vulnerable to environmental contamination, potentially rendering them unsafe for human consumption. Non-invasive gape (valve openness) sensing allows in-situ monitoring of bivalve shellfish behaviours, such as feeding, that can result in exposure to contaminated waters. Sensors were attached to Blue mussels and deployed for 10 days on natural mussel beds in Dundrum Bay, Northern Ireland. Data showed a tidally synchronous behaviour pattern of high openness at high water and vice versa. It is likely that this is, at least in part, due to extreme salinity variation (1.8–33.6) resulting from near total water exchange with each tide in the bay. This behaviour is likely to infer a degree of protection from contaminants during periods of low water, a time at which runoff-derived pollutants are most concentrated

Development of a Grp94 inhibitor

This document is the Accepted Manuscript version of a Published Work that appeared in final form in the Journal of the American Chemical Society, copyright © American Chemical Society after peer review and technical editing by the publisher. To access the final edited and published work see http://doi.org/10.1021/ja303477g.Heat shock protein 90 (Hsp90) represents a promising therapeutic target for the treatment of cancer and other diseases. Unfortunately, results from clinical trials have been disappointing as off-target effects and toxicities have been observed. These detriments may be a consequence of pan-Hsp90 inhibition, as all clinically evaluated Hsp90 inhibitors simultaneously disrupt all four human Hsp90 isoforms. Using a structure-based approach, we designed an inhibitor of Grp94, the ER-resident Hsp90. The effect manifested by compound 2 on several Grp94 and Hsp90α/β (cytosolic isoforms) clients were investigated. Compound 2 prevented intracellular trafficking of the Toll receptor, inhibited the secretion of IGF-II, affected the conformation of Grp94, and suppressed Drosophila larval growth, all Grp94-dependent processes. In contrast, compound 2 had no effect on cell viability or cytosolic Hsp90α/β client proteins at similar concentrations. The design, synthesis, and evaluation of 2 are described herein
