Case-control studies are commonly used to evaluate effectiveness of licensed vaccines after deployment in public health programs. Such studies can provide policy-relevant data on vaccine performance under 'real world' conditions, contributing to the evidence base to support and sustain introduction of new vaccines. However, case-control studies do not measure the impact of vaccine introduction on disease at a population level, and are subject to bias and confounding, which may lead to inaccurate results that can misinform policy decisions. In 2012, a group of experts met to review recent experience with case-control studies evaluating the effectiveness of several vaccines; here we …

Enteropathogenic Escherichia coli (EPEC) are diarrhoeagenic E. coli, and are a significant cause of gastrointestinal illness among young children in developing countries. Typical EPEC are identified by the presence of the bundle-forming pilus encoded by a virulence plasmid, which has been linked to an increased severity of illness, while atypical EPEC lack this feature. Comparative genomics of 70 total EPEC from lethal (LI), non-lethal symptomatic (NSI) or asymptomatic (AI) cases of diarrhoeal illness in children enrolled in the Global Enteric Multicenter Study was used to investigate the genomic differences in EPEC isolates obtained from individuals with various clinical outcomes.

Effect Of Mobile Phone Text Messages Reminders On Uptake Of Routine Immunization Among Children In Pakistan- Study Protocol For A Randomized Clinical Trial, Abdul Momin Kazi, Murtaza Ali, Khurram Zubair, Hussain Kalimuddin, Syed Asad Ali

Department of Paediatrics and Child Health

Introduction: Routine Immunization (RI) is considered one of the best public health interventions to decrease child morbidity and mortality. The RI coverage in Pakistan is still well below the desired level, leading to continued polio transmission, large measles outbreaks and thousands of deaths from vaccine-preventable illnesses. Different innovative and cost effective strategies are required to look into for enhancement in vaccination uptake and coverage. We plan to test the effectiveness of reminders to parents/caregivers on cell phones through short messaging system (SMS) in improving vaccine uptake and on-time routine immunization for children in Pakistan.
Methods and Analysis: A parallel-randomized controlled …


What Can Pakistan Do To Address Maternal And Child Health Over The Next Decade?, Zulfiqar Ahmed Bhutta, Assad Hafeez Nov 2015

What Can Pakistan Do To Address Maternal And Child Health Over The Next Decade?, Zulfiqar Ahmed Bhutta, Assad Hafeez

Department of Paediatrics and Child Health

Pakistan faces huge challenges in meeting its international obligations and agreed Millennium Development Goal targets for reducing maternal and child mortality. While there have been reductions in maternal and under-5 child mortality, overall rates are barely above secular trends and neonatal mortality has not reduced much. Progress in addressing basic determinants, such as poverty, undernutrition, safe water, and sound sanitary conditions as well as female education, is unsatisfactory and, not surprisingly, population growth hampers economic growth and development across the country. The devolution of health to the provinces has created challenges as well as opportunities for action. This paper presents …

Diagnosis And Management Of Preeclampsia In Community Settings In Low And Middle-Income Countries, Rehana A. Salam, Jai K. Das, Anum Ali, Soumyadeep Bhaumik, Zohra S. Lassi

Department of Paediatrics and Child Health

Hypertensive disorders of pregnancy contribute significantly to maternal mortality and morbidity. Preeclampsia belongs to the spectrum of hypertensive disorders of pregnancy and if undiagnosed and/or untreated leads to fatal consequences for both the mother and the baby. Early detection and prevention of preeclampsia is limited by uncertainty in the knowledge about its etiopathogenesis. While much work has been done in establishing clinical guidelines for management of preeclampsia in the hospital or tertiary care settings, there is considerable lack of work in the domain of evidence-based guidelines for screening, identification and management of preeclampsia at the community-level. The article reviews these …

Approaches To Improve Quality Of Care (Qoc) For Women And Newborns: Conclusions, Evidence Gaps And Research Priorities, Zulfiqar Ahmed Bhutta, Rehana A. Salam, Zohra S. Lassi, Anne Austin, Ana Langer

Department of Paediatrics and Child Health

Despite progress in recent years, an estimated 273,500 women died as a result of maternal causes in 2010. The burden of these deaths is disproportionately bourne by women who reside in low income countries or belong to the poorest sectors of the population of middle or high income ones, and it is particularly acute in regions where access to and utilization of facility-based services for childbirth and newborn care is lowest. Evidence has shown that poor quality of facility-based care for these women and newborns is one of the major contributing factors for their elevated rates of morbidity and mortality. …
