Perspectives On Model Forecasts Of The 2014–2015 Ebola Epidemic In West Africa: Lessons And The Way Forward, Gerardo Chowell, Cecile Viboud, Lone Simonsen, Stefano Merler, Alessandro Vespignani

Global Health Faculty Publications

The unprecedented impact and modeling efforts associated with the 2014–2015 Ebola epidemic in West Africa provides a unique opportunity to document the performances and caveats of forecasting approaches used in near-real time for generating evidence and to guide policy. A number of international academic groups have developed and parameterized mathematical models of disease spread to forecast the trajectory of the outbreak. These modeling efforts often relied on limited epidemiological data to derive key transmission and severity parameters, which are needed to calibrate mechanistic models. Here, we provide a perspective on some of the challenges and lessons drawn from these efforts, …

Translating Mental Health Diagnostic And Symptom Terminology To Train Health Workers And Engage Patients In Cross-Cultural, Non-English Speaking Populations, Bibhav Acharya, Madhur Basnet, Pragya Rimal, David Citrin, Soniya Hirachan, Brandon Kohrt, +Several Additional Authors

Psychiatry and Behavioral Sciences Faculty Publications

Although there are guidelines for transcultural adaptation and validation of psychometric tools, similar resources do not exist for translation of diagnostic and symptom terminology used by health professionals to communicate with one another, their patients, and the public. The issue of translation is particularly salient when working with underserved, non-English speaking populations in high-income countries and low- and middle-income countries. As clinicians, researchers, and educators working in cross-cultural settings, we present four recommendations to avoid common pitfalls in these settings. We demonstrate the need for: (1) harmonization of terminology among clinicians, educators of health professionals, and health policymakers; (2) distinction …

Toward Solving The Etiological Mystery Of Primary Biliary Cholangitis, Atsushi Tanaka, Patrick S.C. Leung, Howard A. Young, M. Eric Gershwin Jan 2017

Toward Solving The Etiological Mystery Of Primary Biliary Cholangitis, Atsushi Tanaka, Patrick S.C. Leung, Howard A. Young, M. Eric Gershwin

United States Public Health Resources

Primary biliary cholangitis (PBC) is considered a model autoimmune disease due to its signature anti-mitochondrial antibody (AMA) autoantibody, female predominance, and relatively specific portal infiltration and cholestasis. The identification and cloning of the major mitochondrial autoantigens recognized by AMA have served as an immunologic platform to identify the earliest events involved in loss of tolerance. Despite the relatively high concordance rate in identical twins, genome-wide association studies have not proven clinically useful and have led to suggestions of epigenetic events. To understand the natural history and etiology of PBC, several murine models have been developed, including spontaneous models, models induced …
