Fly Control To Prevent Diarrhoea In Children, Jai K. Das, Yousaf Bashir Hadi, Rehana Salam, Mehar Hoda, Zohra S. Lassi, Zulfiqar Ahmed Bhutta

Department of Paediatrics and Child Health

Background:
Diarrhoeal disease accounts for millions of child deaths every year. Although the role of flies as vectors of infectious diarrhoea has been established, fly control is not often mentioned as an approach to decrease childhood diarrhoea. Theoretically, fly control for decreasing diarrhoea incidence can be achieved by intervening at four different levels: reduction or elimination of fly breeding sites; reduction of sources that attract houseflies; prevention of contact between flies and disease-causing organisms; and protection of people, food, and food utensils from contact with flies.
Objectives:
To assess the impact of various housefly control measures on the incidence of …

Measuring And Understanding Social-Emotional Behaviors In Preschoolers From Rural Pakistan, Jenna E. Finch, Aisha Khizar Yousafzai, Muneera Rasheed, Jelena Obradović

Department of Paediatrics and Child Health

The Strengths and Difficulties Questionnaire (SDQ) is widely-used to measure symptoms of common childhood behavioral problems that may lead to mental health difficulties. In a sample of 1,302 highly-disadvantaged mothers and their preschoolers, we evaluated the factor structure and reliability of the parent-report version of the SDQ in rural Pakistan. Confirmatory factor analyses suggested that the original structure of the SDQ was not appropriate for our data. We created conceptually- and empirically-coherent measures of children’s externalizing behavior problems and prosocial skills. Child and family correlates of social-emotional behaviors were similar to those found in other countries, supporting the validity of …

Multicentre Pilot Study Evaluation Of Lung Ultrasound For The Management Of Paediatric Pneumonia In Low-Resource Settings: A Study Protocol, Jennifer L. Lenahan, Giovanni Volpicelli, Alessandro Lamorte, Fyezah Jehan, Quique Bassat, Amy Sarah Ginsburg

Department of Paediatrics and Child Health

Introduction:
Pneumonia is the leading infectious cause of death among children under 5 years of age worldwide. However, pneumonia is challenging to diagnose. Lung ultrasound (LUS) is a promising diagnostic technology. Further evidence is needed to better understand the role of LUS as a tool for the diagnosis of childhood pneumonia in low-resource settings.
Methods and analysis:
This study aims to pilot LUS in Mozambique and Pakistan and to generate evidence regarding the use of LUS as a diagnostic tool for childhood pneumonia. Children with cough <14 days with chest indrawing (n=230) and without chest indrawing (n=40) are enrolled. World Health Organization Integrated Management of Childhood Illness assessment is performed at enrolment, along with a chest radiograph and LUS examination. Respiratory and blood specimens are collected for viral and bacterial testing and biomarker assessment. Enrolled children are followed for 14 days (in person) and 30 days (phone call) post-enrolment with LUS examinations performed on Days 2, 6 and 14. Qualitative and quantitative data are also collected to assess feasibility, usability and acceptability of LUS among healthcare providers and caregivers. The primary outcome is LUS findings at enrolment with secondary outcomes including patient outcomes, repeat LUS findings, viral and bacterial test results, and patient status after 14 and 30 days of follow-up.
Ethics and dissemination:
This trial was approved by the Western Institutional Review Board as …

Department of Paediatrics and Child Health

Background: Maternal vaccines against pertussis are not yet recommended in the developing world. Besides unclear burden estimates, another concern is that transplacental transfer of maternal pertussis antibodies could result in attenuation of the immune response to whole cell pertussis (DTwP) primary vaccination series in infants. This study was taken up to determine whether higher levels of maternal pertussis antibodies attenuate immune response of infants to DTwP vaccination series given at 6-10-14 weeks of age.
Methodology: A total of 261 pregnant women and their infants from four low-income settlements in Karachi, Pakistan were enrolled in this study. The study endpoints were …

Integrating Facility-Based Surveillance With Healthcare Utilization Surveys To Estimate Enteric Fever Incidence: Methods And Challenges, Jason R. Andrews, Caitlin Barkume, Alexander T. Yu, Samir K. Saha, Farah Qamar, Denise Garrett, Stephen P. Luby

Department of Paediatrics and Child Health

Cohort studies and facility-based sentinel surveillance are common approaches to characterizing infectious disease burden, but present trade-offs; cohort studies are resource-intensive and may alter disease natural history, while sentinel surveillance underestimates incidence in the population. Hybrid surveillance, whereby facility-based surveillance is paired with a community-based healthcare utilization assessment, represents an alternative approach to generating population-based disease incidence estimates with moderate resource investments. Here, we discuss this method in the context of the Surveillance for Enteric Fever in Asia Project (SEAP) study. We describe how data are collected and utilized to adjust enteric fever incidence for blood culture sensitivity, facility-based enrollment, …

Novel Public-Private Partnerships To Address The Double Burden Of Malnutrition, Adam Drewnowski, Benjamin Caballero, Jai K. Das, Jeff French, Andrew M. Prentice, Lisa R. Fries, Tessa M Van Koperen, Petra Klassen-Wigger, Barbara J. Rolls

Department of Paediatrics and Child Health

Public–private partnerships are an effective way to address the global double burden of malnutrition. While public–private partnerships operate in multiple forms, their leadership usually falls to governments, public health agencies, or nongovernmental organizations, with the private sector taking a subordinate role. The rapid ascent of social media and mass communications worldwide has provided a disruptive technology for new nutrition intervention programs. A new model, provisionally called private–public engagement, takes advantage of social media, mass media, and integrated social marketing to reach parents, families, and communities directly. These new private–public engagement initiatives need to be managed in ways suggested for public–private …
