Bann, K Michael Hambidge, Ana L. Garces, Lester Figueroa, Jamie L. Westcott, Jackie K. Patterson, Elizabeth M. Mcclure, Sumera Ali Aziz, Sarah Saleem

Community Health Sciences

Background: Adequate gestational weight gain (GWG) is essential for healthy fetal growth. However, in low- and middle-income countries, where malnutrition is prevalent, little information is available about GWG and how it might be modified by nutritional status and interventions.
Objective: We describe GWG and its associations with fetal growth and birth outcomes. We also examined the extent to which prepregnancy BMI, and preconception and early weight gain modify GWG, and its effects on fetal growth.
Methods: This was a secondary analysis of the Women First Trial, including 2331 women within the Democratic Republic of Congo (DRC), Guatemala, India, and Pakistan, …

Nolen, Jackie Patterson, Adrien Lokangaka, Antoinette Tshefu, Archana B. Patel, Patricia L. Hibberd, Sarah Saleem, Saleem Jessani

Community Health Sciences

Background: Due to high fertility rates in some low and lower-middle income countries, the interval between pregnancies can be short, which may lead to adverse maternal and neonatal outcomes.
Methods: We analyzed data from women enrolled in the NICHD Global Network Maternal Newborn Health Registry (MNHR) from 2013 through 2018. We report maternal characteristics and outcomes in relationship to the inter-delivery interval (IDI, time from previous delivery [live or stillborn] to the delivery of the index birth), by category of 6-17 months (short), 18-36 months (reference), 37-60 months, and 61-180 months (long). We used non-parametric tests for maternal characteristics, and …

Health Care Seeking For Maternal And Newborn Illnesses In Low- And Middle-Income Countries: A Systematic Review Of Observational And Qualitative Studies, Zohra S. Lassi, Philippa Middleton, Zulfiqar Ahmed Bhutta, Caroline Crowther

Woman and Child Health

Background: In low- and middle-income countries, a large number of maternal and newborn deaths occur due to delays in health care seeking. These delays occur at three levels i.e. delay in making decision to seek care, delay in access to care, and delay in receiving care. Factors that cause delays are therefore need to be understand to prevent and avoid these delays to improve health and survival of mothers and babies.
Methods: A systematic review of observational and qualitative studies to identify factors and barriers associated with delays in health care seeking.
Results: A total of 159 observational and qualitative …

Status Of Paratyphoid Fever Vaccine Research And Development, Laura B. Martin, Raphael Simon, Calman A. Maclennan, Sharon M. Tennant, Sushant Sahastrabuddhe, M. Imran Khan

Centre of Excellence in Women and Child Health

Salmonella enterica serovars Typhi and Paratyphi (S. Paratyphi) A and B cause enteric fever in humans. Of the paratyphoid group, S. Paratyphi A is the most common serovar. In 2000, there were an estimated 5.4 million cases of S. Paratyphi A worldwide. More recently paratyphoid fever has accounted for an increasing fraction of all cases of enteric fever. Although vaccines for typhoid fever have been developed and in use for decades, vaccines for paratyphoid fever have not yet been licensed. Several S. Paratyphi A vaccines, however, are in development and based on either whole cell …

Nontyphoidal Salmonella Disease: Current Status Of Vaccine Research And Development, Sharon M. Tennant, Calman A. Maclennan, Raphael Simon, Laura B. Martin, M. Imran Khan

Centre of Excellence in Women and Child Health

Among more than 2500 nontyphoidal Salmonella enterica (NTS) serovars, S. enterica serovar Typhimurium and S. enterica serovar Enteritidis account for approximately fifty percent of all human isolates of NTS reported globally. The global incidence of NTS gastroenteritis in 2010 was estimated to be 93 million cases, approximately 80 million of which were contracted via food-borne transmission. It is estimated that 155,000 deaths resulted from NTS in 2010. NTS also causes severe, extra-intestinal, invasive bacteremia, referred to as invasive nontyphoidal Salmonella (iNTS) disease. iNTS disease usually presents as a febrile illness, frequently without gastrointestinal symptoms, in both adults and children. Symptoms …

Perinatal Distress In Women In Low- And Middle-Income Countries: Allostatic Load As A Framework To Examine The Effect Of Perinatal Distress On Preterm Birth And Infant Health, Shahirose Sadrudin Premji

School of Nursing & Midwifery

In low- and middle-income countries (LMIC), determinants of women's and children's health are complex and differential vulnerability may exist to risk factors of perinatal distress and preterm birth. We examined the contribution of maternal perinatal distress on preterm birth and infant health in terms of infant survival and mother-infant interaction. A critical narrative and interpretive literature review was conducted. Peer-reviewed electronic databases (MEDLINE, Embase, Global Health, CINHAL), grey literature, and reference lists were searched, followed by a consultation exercise. The literature was predominantly from high-income countries. We identify determinants of perinatal distress and explicate changes in the hypothalamic-pituitary-adrenal axis, sympathetic, …

Neonatal Vitamin A Supplementation For The Prevention Of Mortality And Morbidity In Term Neonates In Developing Countries, Batool A. Haider, Zulfiqar Ahmed Bhutta

Woman and Child Health

Background:Vitamin A deficiency is a major public health problem in developing countries. Vitamin A supplementation in children greater than six months of age has been found to be beneficial, with no effect of supplementation between one to five months. Supplementation in the neonatal period has been suggested to have an impact by increasing body stores in early infancy.
Objectives: To evaluate the role of vitamin A supplementation in term neonates in developing countries with respect to the prevention of mortality and morbidity.
Search strategy: We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library, May …

Leon Ochiai, Linda Kaljee, Baiqing Dong, Dipika Sur, S.K. Bhattacharya, Siti Sapardiyah Santoso, Magdarina Agtini, Zahid Memon, Zulfiqar Ahmed Bhutta, Canh Gia Do, Lorenz Von Seidlein, John Clemens

Centre of Excellence in Women and Child Health

This study was undertaken to develop a model to predict the incidence of typhoid in children based on adults’ perception of prevalence of enteric fever in the wider community. Typhoid cases among children, aged 5-15 years, from epidemic regions in five Asian countries were confirmed with a positive Salmonella Typhi culture of the blood sample. Estimates of the prevalence of enteric fever were obtained from random samples of adults in the same study sites. Regression models were used for establishing the prediction equation. The percentages of enteric fever reported by adults and cases of typhoid incidence per 100,000, detected through …
