The prevalence of SGA ranged from 10.5% to 72.5% in Nepal, and 12.0% to 78.4% in …


Telehealth: Into The Mainstream?, Lisa Sprague Mar 2014

Telehealth: Into The Mainstream?, Lisa Sprague

National Health Policy Forum

Teleheath, and its subset telemedicine, extend across a range of technologies allowing patients to seek diagnosis, treatment, and other services from clinicians by electronic means. Telephone, videoconferencing, iPads, and apps are all employed. In its most established form, hospitals and medical centers use telehealth to reach patients in underserved rural areas. Proponents of telehealth suggest it can relieve medical workforce shortages; save patients time, money, and travel; reduce unnecessary hospital visits; improve the management of chronic conditions; and improve continuing medical education. But telehealth also faces ongoing challenges. States require physicians to be licensed in each state where they treat …

Money Follows The Person (Mfp) Rebalancing Demonstration: A Work In Progress, Carol O'Shaughnessy

National Health Policy Forum

In recent years, federal and state policy efforts have expanded opportunities for people to live in home- and community-based settings rather than in nursing homes and other institutions. As part of the Deficit Reduction Act of 2005, Congress enacted the Money Follows the Person Rebalancing (MFP) program, a Medicaid demonstration to help people who need long-term services and supports (LTSS) transition from nursing homes and other institutions to their own homes or other community settings. The Patient Protection and Affordable Care Act of 2010 extended the program through September 30, 2016. Now in its eighth year of operation, MFP grants …

Humidity And Gravimetric Equivalency Adjustments For Nephelometer-Based Particulate Matter Measurements Of Emissions From Solid Biomass Fuel In Cookstoves, Sutyajeet Soneja, Chen Chen, James M. Tielsch, Joanne Katz, Scott L. Zeger, William Checkley, Frank C. Curriero, Patrick L. Breysse

Global Health Faculty Publications

Great uncertainty exists around indoor biomass burning exposure-disease relationships due to lack of detailed exposure data in large health outcome studies. Passive nephelometers can be used to estimate high particulate matter (PM) concentrations during cooking in low resource environments. Since passive nephelometers do not have a collection filter they are not subject to sampler overload. Nephelometric concentration readings can be biased due to particle growth in high humid environments and differences in compositional and size dependent aerosol characteristics. This paper explores relative humidity (RH) and gravimetric equivalency adjustment approaches to be used for the

pDR-1000 used to assess indoor PM …

Analysis Of Schizophrenia Data Using A Nonlinear Threshold Index Logistic Model., Zhenyu Jiang, Chengan Du, Assen Jablensky, Hua Liang, Zudi Lu, Yang Ma, Kok Lay Teo

GW Biostatistics Center

Genetic information, such as single nucleotide polymorphism (SNP) data, has been widely recognized as useful in prediction of disease risk. However, how to model the genetic data that is often categorical in disease class prediction is complex and challenging. In this paper, we propose a novel class of nonlinear threshold index logistic models to deal with the complex, nonlinear effects of categorical/discrete SNP covariates for Schizophrenia class prediction. A maximum likelihood methodology is suggested to estimate the unknown parameters in the models. Simulation studies demonstrate that the proposed methodology works viably well for moderate-size samples. The suggested approach is therefore …

Mediation Analysis Of Gestational Age, Congenital Heart Defects, And Infant Birth-Weight, Adane Wogu, Christopher Loffredo, Ionut Bebu, George Luta

GW Biostatistics Center

Background

In this study we assessed the mediation role of the gestational age on the effect of the infant’s congenital heart defects (CHD) on birth-weight.

Methods

We used secondary data from the Baltimore-Washington Infant Study (1981–1989). Mediation analysis was employed to investigate whether gestational age acted as a mediator of the association between CHD and reduced birth-weight. We estimated the mediated effect, the mediation proportion, and their corresponding 95% confidence intervals (CI) using several methods.

Results

There were 3362 CHD cases and 3564 controls in the dataset with mean birth-weight of 3071 (SD = 729) and 3353 (SD = 603) …
