Global Health Faculty Publications

BACKGROUND: Adverse birth outcomes, including low birth weight (LBW), defined as <2500 >grams, small-for-gestational-age (SGA), and prematurity, contribute to 60%-80% of infant mortality worldwide and may be related to infections during pregnancy. The aim of this study was to assess whether febrile human rhinovirus (HRV) illness is associated with adverse birth outcomes.

METHODS: Active household-based weekly surveillance was performed for respiratory illness episodes in pregnant women as part of a community-based, prospective, randomized trial of maternal influenza immunization in rural Nepal. Rhinovirus (HRV) febrile illness episodes were defined as fever plus cough, sore throat, runny nose, and/or myalgia with HRV detected …

Regulatory Elements On Marijuana, For The Effective Population Health Protection, C Santos-Burgoa

Global Health Faculty Publications

When discussing the public health approach to the use of marijuana, the complexity of rigorous regulatory interventions for population protection is omitted. Using the experience of governments where these practices already exist, regulation is introduced as an essential public health function, spelling out seven purposes for controlling marijuana. The technical elements of institutional capacity -including the technical and financial capacity- and of governance that must be covered by any rigorous regulation of its use are detailed below. The difficulty of regulating psychoactive substances is addressed when considering the capacity to control other legal substances manifested with their increased consumption. It …

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, …

From Sea To Shining Sea, And The Great Plains To Patagonia: A Review On Current Knowledge Of Diabetes Mellitus In Hispanics/Latinos In The U.S. And Latin America, Larissa Aviles-Santa, Uriyoán Colon-Ramos, Nangel Lindberg, Joseimer Mattei, Francisco Pasquel, Cynthia Perez

Global Health Faculty Publications

The last two decades have witnessed many advances in the prevention, treatment, and control of diabetes mellitus and its complications. Increased screening has led to a greater recognition of Type 2 diabetes mellitus (Type 2 DM) and prediabetes; however, Hispanics/Latinos, the largest minority group in the U.S., have not fully benefited from these advances. The Hispanic/Latino population is highly diverse in ancestries, birth places, cultures, languages, and socioeconomic backgrounds, and it populates most of the Western Hemisphere. In the U.S., the prevalence of diabetes mellitus varies among Hispanic/Latino heritage groups, being higher among Mexicans, Puerto Ricans, and Dominicans, and lower …

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 …

High concentrations of household air pollution (HAP) due to biomass fuel usage with unvented, insufficient combustion devices are thought to be an important health risk factor in South Asia population. To better characterize the indoor concentrations of particulate matter (PM2.5) and carbon monoxide (CO), and to understand their impact on health in rural southern Nepal, this study analyzed daily monitoring data collected with DataRAM pDR-1000 and LASCAR CO data logger in 2980 households using traditional biomass cookstove indoor through the Nepal Cookstove Intervention Trial–Phase I between March 2010 and October 2011. Daily average PM2.5 and CO concentrations collected in area …

A Generalized-Growth Model To Characterize The Early Ascending Phase Of Infectious Disease Outbreaks, Cecile Viboud, Lone Simonsen, Gerardo Chowell

Global Health Faculty Publications

Background

A better characterization of the early growth dynamics of an epidemic is needed to dissect the important drivers of disease transmission, refine existing transmission models, and improve disease forecasts.

Materials and methods

We introduce a 2-parameter generalized-growth model to characterize the ascending phase of an outbreak and capture epidemic profiles ranging from sub-exponential to exponential growth. We test the model against empirical outbreak data representing a variety of viral pathogens in historic and contemporary populations, and provide simulations highlighting the importance of sub-exponential growth for forecasting purposes.

Results

We applied the generalized-growth model to 20 infectious disease outbreaks representing …

Effect Of An Improved Biomass Stove On Acute Lower Respiratory Infections In Young Children In Rural Nepal: A Cluster-Randomised, Step-Wedge Trial, James M. Tielsch, Joanne Katz, Subarna K. Khatry, Laxman Shrestha, Patrick N. Breysse, Scott L. Zeger, +5 Additional Authors

Global Health Faculty Publications

Background

Acute lower respiratory infections (ALRI) are an important cause of death in young children in low income countries. High concentrations of fine particulate matter (PM2.5) indoors caused by open burning of biomass are associated with risk of ALRI. However, improved biomass stoves reduce emissions and might reduce the incidence of lower respiratory illness. A cluster-randomised, step-wedge, community-based trial was conducted to estimate the eff ect that a change from open burning of biomass to improved biomass stoves could have on rates of ALRI in children younger than 36 months in a rural area of southern Nepal.

Methods

Global Health Faculty Publications

Background

Approximately 2·3 million fetal, neonatal, or maternal deaths occur annually during the intrapartum period or on the day of birth. Several risk factors for intrapartum-related complications require ultrasonography for accurate diagnosis, but sonographic services are scarce in low-resource settings. In this study, we aimed to assess the feasibility of community-based ultrasonography conducted by auxiliary nurse midwives to identify basic obstetric risk factors, in rural Sarlahi District, Nepal. We aimed to assess the validity at which these health workers can detect noncephalic position, multiple gestation, and placenta previa and to explore whether sonographic diagnosis could improve outcomes for women with …

Unintended Pregnancies In Brazil - A Challenge For The Recommendation To Delay Pregnancy Due To Zika, Cynthia Schuck-Paim, Daniel Lopez, Lone Simonsen, Wladimir Alonso

Global Health Faculty Publications

Because of the potential link between the ongoing Zika virus outbreak and a surge in the number of cases of congenital microcephaly, officials in Latin America have recommended that women postpone pregnancy until this association is firmly established or the outbreak subsides. However, in all these countries a large proportion of babies are still born out of unplanned pregnancies. Teenage girls are particularly at high risk, as they often lack access to preventive contraception methods, or the knowledge to use them appropriately. To gauge the magnitude of the barriers preventing the implementation of such a recommendation in Brazil, the country …

Infant Vaccination Timing: Beyond Traditional Coverage Metrics For Maximizing Impact Of Vaccine Programs, An Example From Southern Nepal., Michelle M Hughes, Joanne Katz, Janet A Englund, Subarna K Khatry, Laxman Shrestha, Steven C Leclerq, Mark Steinhoff, James M. Tielsch

Global Health Faculty Publications

Background

Immunization programs currently measure coverage by assessing the proportion of children 12–24 months who have been immunized but this does not address the important question of when the scheduled vaccines were administered. Data capturing the timing of vaccination in first 6 months, when severe disease is most likely to occur, are limited.

Objective

To estimate the time to Bacillus Calmette–Guérin (BCG) (recommended at birth), diphtheria-tetanus-pertussis-H, influenza b-hepatitis B (DTP-Hib-HepB), and oral polio vaccine (OPV) (recommended at 6, 10, and 14 weeks) vaccinations and risk factors for vaccination delay in infants <6 months of age in a district in southern Nepal where traditional coverage metrics are high.

Design/methods

Infants enrolled in a randomized controlled trial of …

Global Health Faculty Publications

Background

Maternal and Child Health (MCH) Handbook, an integrated MCH home-based record, was piloted in four provinces of Vietnam (Dien Bien, Hoa Binh, Thanh Hoa and An Giang). The study is aimed at assessing the changes in pregnant women’s behavior towards the frequencies of their antenatal care service utilizations and their subsequent breastfeeding practices up to six months of age, through the MCH Handbook intervention. This is because the levels of pregnant women’s knowledge, attitude and practices (KAP) towards their antenatal care service utilizations and exclusive breastfeeding practices have been previously neither analyzed nor reported in relation to MCH home-based …

Fragmented Implementation Of Maternal And Child Health Home-Based Records In Vietnam: Need For Integration, Hirotsugu Aiga, Vinh Duc Nguyen, Cuong Dinh Nguyen, Tho Thi Thi Nguyen, Lien Thi Phuong Nguyen

Global Health Faculty Publications

Background: Home-based records (HBRs) are globally implemented as the effective tools that encourage pregnant women and mothers to timely and adequately utilise maternal and child health (MCH) services. While availability and utilisation of nationally representative HBRs have been assessed in several earlier studies, the reality of a number of HBRs subnationally implemented in a less coordinated manner has been neither reported nor analysed.

Objectives: This study is aimed at estimating the prevalence of HBRs for MCH and the level of fragmentation of and overlapping between different HBRs for MCH in Vietnam. The study further attempts to identify health …

Global Mortality Impact Of The 1957–1959 Influenza Pandemic, Cecile Viboud, Lone Simonsen, Rodrigo Fuentes, Jose Flores, Mark A. Miller, Gerardo Chowell

Global Health Faculty Publications

Background. Quantitative estimates of the global burden of the 1957 influenza pandemic are lacking. Here we fill this gap by modeling historical mortality statistics.

Methods. We used annual rates of age- and cause-specific deaths to estimate pandemic-related mortality in excess of background levels in 39 countries in Europe, the Asia-Pacific region, and the Americas. We modeled the relationship between excess mortality and development indicators to extrapolate the global burden of the pandemic.

Results. The pandemic-associated excess respiratory mortality rate was 1.9/10 000 population (95% confidence interval [CI], 1.2–2.6 cases/10 000 population) on average during 1957–1959. Excess mortality rates varied 70-fold …

A New Look At Care In Pregnancy: Simple, Effective Interventions For Neglected Populations, Stephen Hodgins, James M. Tielsch, Kristen Rankin, Amber Robinson, Annie Kearns, Jacquelyn Caglia

Global Health Faculty Publications

Background

Although this is beginning to change, the content of antenatal care has been relatively neglected in safe-motherhood program efforts. This appears in part to be due to an unwarranted belief that interventions over this period have far less impact than those provided around the time of birth. In this par, we review available evidence for 21 interventions potentially deliverable during pregnancy at high coverage to neglected populations in low income countries, with regard to effectiveness in reducing risk of: maternal mortality, newborn mortality, stillbirth, prematurity and intrauterine growth restriction. Selection was restricted to interventions that can be provided by …

Global Health Faculty Publications

Background

Radical regulations to improve air quality, including traffic control, were implemented prior to and during the 2008 Beijing Olympic Games. Consequently, ambient concentrations of nitrogen dioxide (NO ₂ ) and particular matter 10 micrometers or less (PM ₁₀ ), were reduced in a distinct and short window of time, which presented a natural experiment for testing the relationships between maternal exposure to PM ₁₀ and NO ₂ during pregnancy and adverse birth outcomes.

Methods

We estimated the effect of PM ₁₀ and NO ₂ exposure during each trimester of gestation on the risk of preterm birth among live births …

Fetal, Neonatal, Infant, And Child International Growth Standards: An Unprecedented Opportunity For An Integrated Approach To Assess Growth And Development., Cutberto Garza

Global Health Faculty Publications

The recent publication of fetal growth and gestational age-specific growth standards by the International Fetal and Newborn Growth Consortium for the 21st Century Project and the previous publication by the WHO of infant and young child growth standards based on the WHO Multicentre Growth Reference Study enable evaluations of growth from ∼9 wk gestation to 5 y. The most important features of these projects are the prescriptive approach used for subject selection and the rigorous testing of the assertion that growth is very similar among geographically and ethnically diverse nonisolated populations when health, nutrition, and other care needs are met …
