Global Health Faculty Publications

PURPOSE: Although there is a growing evidence base on the drivers of child marriage, comparatively little is known about the experiences of married girls in refugee settings and how their development trajectories diverge from those of their nonmarried peers, particularly in the context of the COVID-19 pandemic. Drawing on cross-national panel data from Bangladesh and Jordan, this article explores diversity in child marriage experiences in contexts affected by forced displacement, highlighting how married girls' well-being differs from that of their unmarried peers, and how COVID-19 has reinforced these differences.

METHODS: We analyzed longitudinal survey data-collected pre- and post-COVID-19-from the Gender …

Influenza is an important cause of illness and morbidity for infants. Seasonal influenza vaccination during pregnancy aims to provide protection to mothers, but it can also provide immunity to infants. The precise influence of maternal vaccination on immunity in infants and how vaccine-elicited antibodies provide protection in some but not all infants is incompletely understood. We comprehensively profiled the transfer of functional antibodies and defined humoral factors contributing to immunity against influenza in a clinical trial of maternal influenza vaccination. Influenza-specific antibody subclass levels, Fc ɣ receptor (FCGR) binding levels, and antibody-dependent innate immune functions were all profiled in the …

How Medicaid And States Could Better Meet Health Needs Of Persons Experiencing Homelessness., Sana Charania

Student Works

An estimated 580 000 people experienced homelessness on any single night in the United States in 2020. This article argues that, to address these persons' unmet needs, Medicaid should collaborate with clinicians and state programs to provide permanent supportive housing and housing support services to individuals experiencing homelessness. Access to shelter can improve health outcomes for individuals experiencing homelessness and reduce overall health care costs.

Nutrition, A Tenet Of Lifestyle Medicine But Not Medicine?, Leigh A. Frame Jun 2021

Nutrition, A Tenet Of Lifestyle Medicine But Not Medicine?, Leigh A. Frame

Clinical Research and Leadership Faculty Publications

Nutrition is a foundation of health and one of six pillars of Lifestyle Medicine. The importance of nutrition in clinical care is now widely recognized by health care professionals and the public. However, clinicians are not comfortable counselling their patients on nutrition due to inadequate or lack of training, leaving a significant need in patient care. This gap can be closed with evidence-based curricula in medical schools and in the trainings of other health care professionals. This communication presents the current state of nutrition knowledge in health care, emphasizing nutrition education for physicians, and presents a model of how pre- …

Use Of Placebo In Supplementation Studies-Vitamin D Research Illustrates An Ethical Quandary., Leigh A. Frame, Jonathan P. Fischer, Gail Geller, Lawrence J Cheskin

Clinical Research and Leadership Faculty Publications

History has shown that without explicit and enforced guidelines, even well-intentioned researchers can fail to adequately examine the ethical pros and cons of study design choices. One area in which consensus does not yet exist is the use of placebo groups in vitamin supplementation studies. As a prime example, we focus on vitamin D research. We aim to provide an overview of the ethical issues in placebo-controlled studies and guide future discussion about the ethical use of placebo groups. Research in the field of vitamin D shows variation in how placebo groups are used. We outline four types of control …


A Statistical Method For The Conservative Adjustment Of False Discovery Rate (Q-Value)., Yinglei Lai Mar 2017

A Statistical Method For The Conservative Adjustment Of False Discovery Rate (Q-Value)., Yinglei Lai

Epidemiology Faculty Publications

BACKGROUND: q-value is a widely used statistical method for estimating false discovery rate (FDR), which is a conventional significance measure in the analysis of genome-wide expression data. q-value is a random variable and it may underestimate FDR in practice. An underestimated FDR can lead to unexpected false discoveries in the follow-up validation experiments. This issue has not been well addressed in literature, especially in the situation when the permutation procedure is necessary for p-value calculation.

RESULTS: We proposed a statistical method for the conservative adjustment of q-value. In practice, it is usually necessary to calculate p-value by a permutation procedure. …

Concluding Commentary: Children In All Cancer Prevention Policy Decisions., Cynthia F Bearer, Lynn Goldman

Environmental and Occupational Health Faculty Publications

This interesting series of articles on Opportunities for Cancer Prevention During Early Life brings many ideas for the primary prevention of cancer in childhood, or in adults due to early life events. The economic burden not only of cancer mortality but also of lifelong morbidity among cancer survivors, as shown by Guy et al,1 raises the importance of this critical public health issue. The topics of these articles were developed during online seminars with the pioneers in this area, some of whom authored the articles. They reflect the determinants of health diagrammed so eloquently in Healthy People 2020.2 …


Characterizing The Reproduction Number Of Epidemics With Early Subexponential Growth Dynamics., Gerardo Chowell, Cécile Viboud, Lone Simonsen, Seyed M Moghadas Oct 2016

Characterizing The Reproduction Number Of Epidemics With Early Subexponential Growth Dynamics., Gerardo Chowell, Cécile Viboud, Lone Simonsen, Seyed M Moghadas

Global Health Faculty Publications

Early estimates of the transmission potential of emerging and re-emerging infections are increasingly used to inform public health authorities on the level of risk posed by outbreaks. Existing methods to estimate the reproduction number generally assume exponential growth in case incidence in the first few disease generations, before susceptible depletion sets in. In reality, outbreaks can display subexponential (i.e. polynomial) growth in the first few disease generations, owing to clustering in contact patterns, spatial effects, inhomogeneous mixing, reactive behaviour changes or other mechanisms. Here, we introduce the generalized growth model to characterize the early growth profile of outbreaks and estimate …

Prevention and Community Health Faculty Publications

BACKGROUND: Public health has multicultural origins. By the close of the nineteenth century, Schools of Public Health (SPHs) began to emerge in western countries in response to major contemporary public health challenges. The Flexner Report (1910) emphasized the centrality of preventive medicine, sanitation, and public health measures in health professional education. The Alma Ata Declaration on Primary Health Care (PHC) in 1978 was a critical milestone, especially for low and middle-income countries (LMICs), conceptualizing a close working relationship between PHC and public health measures. The Commission on Social Determinants of Health (2005-2008) strengthened the case for SPHs in LMICs as …

Detection Of Zoonotic Enteropathogens In Children And Domestic Animals In A Semirural Community In Ecuador., Karla Vasco, Jay P Graham, Gabriel Trueba

Environmental and Occupational Health Faculty Publications

UNLABELLED: Animals are important reservoirs of zoonotic enteropathogens, and transmission to humans occurs more frequently in low- and middle-income countries (LMICs), where small-scale livestock production is common. In this study, we investigated the presence of zoonotic enteropathogens in stool samples from 64 asymptomatic children and 203 domestic animals of 62 households in a semirural community in Ecuador between June and August 2014. Multilocus sequence typing (MLST) was used to assess zoonotic transmission of Campylobacter jejuni and atypical enteropathogenic Escherichia coli (aEPEC), which were the most prevalent bacterial pathogens in children and domestic animals (30.7% and 10.5%, respectively). Four sequence types …

Health Policy and Management Faculty Publications

Abstract

Background

We assessed the predictive accuracy of an empirically-derived score (weight loss, insulin resistance, and glycemic control: “WIG”) to predict patients who will be successful in reducing diabetes mellitus (DM) medication use with weight loss.

Methods

Case records of 121 overweight and obese patients with DM at two outpatient weight management centers were analyzed.

Results

Mean period of follow-up was 12.5 ± 3.5 months. To derive the “WIG” scoring algorithm, one point each was assigned to “W” (loss of 5% of initial body weight within the first 3 months of attempting weight loss), “I” (triglyceride [TGL]/highdensity lipoprotein ratio >3 …

Epidemiology Faculty Publications

Background. To examine whether the US EPA (2010) lung cancer risk estimate derived from the high arsenic exposures (10-934 µg/L) in southwest Taiwan accurately predicts the US experience from low arsenic exposures (3-59 µg/L). Methods. Analyses have been limited to US counties solely dependent on underground sources for their drinking water supply with median arsenic levels of ≥3 µg/L. Results. Cancer risks (slopes) were found to be indistinguishable from zero for males and females. The addition of arsenic level did not significantly increase the explanatory power of the models. Stratified, or categorical, analysis yielded relative risks that hover about 1.00. …

Global Health Faculty Publications

Background

We use data from rural Nepal and South India to compare the prevalence of small-for-gestational-age (SGA) and neonatal mortality risk associated with SGA using different birth-weight-for-gestation reference populations.

Methods

We identified 46 reference populations in low-, middle-, and high-income countries, of which 26 met the inclusion criteria of being commonly cited and having numeric 10th percentile cut points published. Those reference populations were then applied to populations from two community-based studies to determine SGA prevalence and its relative risk of neonatal mortality.

Results

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

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 …
