Expanded HTA: Enhancing Fairness and Legitimacy
All societies face the need to make judgments about what interventions (both public health and personal
medical) to provide to their populations under reasonable resource constraints. Their decisions should be
informed by good evidence and arguments from health technology assessment (HTA). But if HTA restricts
itself to evaluations of safety, efficacy, and cost-effectiveness, it risks being viewed as insufficient to guide health
decision-makers; if it addresses other issues, such as budget impact, equity, and financial protection, it may be
accused of overreaching. But the risk of overreaching can be reduced by embedding HTA in a fair, deliberative
process that meets the conditions required by accountability for reasonableness
Household Pesticides and the Risk of Wilms Tumor
BACKGROUND: Previous epidemiologic studies have suggested that exposure to pesticides in utero and during early childhood may increase the risk for development of childhood cancer, including Wilms tumor, a childhood kidney tumor. OBJECTIVES: In this analysis we evaluated the role of residential pesticide exposure in relation to the risk of Wilms tumor in children using data from a North American caseācontrol study. METHODS: The National Wilms Tumor Study Group (NWTSG) collected information on exposure to residential pesticides from the month before pregnancy through the diagnosis reference date using detailed phone interviews from 523 case mothers and 517 controls frequency matched on childās age and geographic region and identified by list-assisted random digit dialing. Pesticides were grouped according to type of pesticide and where they were used. RESULTS: A slightly increased risk of Wilms tumor was found among children of mothers who reported insecticide use [odds ratio (OR) = 1.4, 95% confidence interval (CI), 1.0ā1.8; adjusted for education, income, and the matching variables]. Results from all other categories of pesticides were generally close to the null. CONCLUSIONS: This study is the largest caseācontrol study of Wilms tumor to date. We were unable to confirm earlier reports of an increased risk for Wilms tumor among those exposed to residential pesticides during pregnancy through early childhood
Aldehyde dehydrogenase inhibition blocks mucosal fibrosis in human and mouse ocular scarring
Mucous membrane pemphigoid (MMP) is a systemic mucosal scarring disease, commonly causing blindness, for which there is no antifibrotic therapy. Aldehyde dehydrogenase (ALDH) family 1 is upregulated in both ocular MMP (OMMP) conjunctiva and cultured fibroblasts. Application of the ALDH metabolite, retinoic acid (RA), to normal human conjunctival fibroblasts in vitro induced a diseased phenotype. Conversely, application of ALDH inhibitors, including disulfiram, to OMMP fibroblasts in vitro restored their functionality to that of normal controls. ALDH1 is also upregulated in the mucosa of the mouse model of scarring allergic eye disease, used here as a surrogate for OMMP, in which topical application of disulfiram decreased fibrosis in vivo. These data suggest that progressive scarring in OMMP results from ALDH/RA fibroblast autoregulation, that the ALDH1 subfamily has a central role in immune-mediated ocular mucosal scarring, and that ALDH inhibition with disulfiram is a potential, and readily translatable, antifibrotic therapy
Unifying Multi-State Efforts through a Nationally Coordinated Extension Diabetes Program
The Cooperative Extension System translates research to practice and ābrings the University to the peopleā throughout the U.S. However, the system suffers from program duplication and is challenged to scale-out effective programs. One program, Dining with Diabetes (DWD), stands out for its dissemination to multiple states. DWD is a community-based program aimed at improving diabetes management, nutrition, and physical activity behaviors. DWD was coordinated through a national working group and implemented by state Extension systems. A pragmatic, quasi-experimental study was conducted to determine the effectiveness of the national coordination model and the overall impact of DWD. Four states reported data representing 355 DWD participants. Significant differences were found in diabetes management behaviors and knowledge from pre to post-program. However, there were challenges with data analysis due to state differences in data management. We detail the transition from one state to a national workgroup, strengths and challenges of the national model, and implications for other Extension programs
