Ventricular Depolarisation Vectors In Exercise Induced Myocardial Ischaemia, Cameruddin W. Vellani, Mohammad Yusuf, Sadia Mahmud, Satwat Hashmi Nov 2017

Ventricular Depolarisation Vectors In Exercise Induced Myocardial Ischaemia, Cameruddin W. Vellani, Mohammad Yusuf, Sadia Mahmud, Satwat Hashmi

Section of Cardiology

Ischaemia reduces membrane excitability and conduction of myocardial depolarisation. This would alter the synergy of electromotive forces that contribute to a resultant force at any instant. Changes in magnitude and direction of resultant forces are reflected in electrocardiographic signals. Here we show a method for obtaining the coordinates of resultant electrical forces during exercise derived from a bipolar orthogonal lead system for calculation of electrical vectors in three planes. In a trial, analysis of changes in vectors indicated that the extent of reduction in magnitude with exercise was significantly greater in groups of patients categorized by impaired effort tolerance and …

Frequency Of G6pd Mediterranean In Individuals With And Without Malaria In Southern Pakistan, Bushra Moiz, Haroon Muhammad Arshad, Ahmed Raheem Raheem, Hasan Hayat, Najia Karim Ghanchi, M Asim Beg

Department of Pathology and Laboratory Medicine

Background: Pakistan has an estimated annual burden of 1.5 million malaria cases. The current situation calls for an efective malaria control and eradication programme in this country. Currently, primaquine is an attractive option for eliminating reservoirs of Plasmodium vivax hypnozoites and killing gametocytes of Plasmodium falciparum. However, this drug causes haemolysis in individuals who are glucose-6-phosphate (G6PD) defcient. It is important to map G6PD defciency and malaria distribution in Pakistan to design an efective malaria eradication regimen. Frequency of G6PD defciency (G6PDd) in malaria patients has not been reported from Pakistan in any meaningful way. The purpose of this study …

Department of Paediatrics and Child Health

From 2014 to 2017, the World Health Organization convened a working group to evaluate influenza disease burden and vaccine efficacy to inform estimates of maternal influenza immunization program impact. The group evaluated existing systematic reviews and relevant primary studies, and conducted four new systematic reviews. There was strong evidence that maternal influenza immunization prevented influenza illness in pregnant women and their infants, although data on severe illness prevention were lacking. The limited number of studies reporting influenza incidence in pregnant women and infants under six months had highly variable estimates and underrepresented low- and middle-income countries. The evidence that maternal …

At The Heart Of The Problem: Health In Johannesburg's Inner-City, Helen Rees, Sinead Delany-Moretlwe, Fiona Scorgie, Stanley Luchters, Matthew F. Chersich

Population Health, East Africa

Urban life in the twenty-first century is marked by numerous stresses and shocks, resulting from rapid urbanisation, frequent migration and crowding, massive unemployment, climate change, physical disasters, and disease outbreaks, among other challenges. This reality – according to the ‘100 Resilient Cities’ initiative of the Rockefeller Foundation – is why the concept of resilience is critical to a sustainable future: cities must learn to “survive and thrive, regardless of the challenge” [1]. In cities in the global South that face a heavy HIV burden, this health crisis is often inseparable from a wider set of interlinked social challenges, ranging from …

The case-control methodology is frequently used to evaluate vaccine effectiveness post-licensure. The results of such studies provide important insight into the level of protection afforded by vaccines in a 'real world' context, and are commonly used to guide vaccine policy decisions. However, the potential for bias and confounding are important limitations to this method, and the results of a poorly conducted or incorrectly interpreted case-control study can mislead policies. In 2012, a group of experts met to review recent experience with case-control studies evaluating vaccine effectiveness; we summarize the recommendations of that group regarding best practices for data collection, analysis, …

Department of Paediatrics and Child Health

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 …

Background: Preterm birth (PTB) remains the leading cause of neonatal mortality and long term disability throughout the world. Though complex in its origins, a growing body of evidence suggests that first trimester administration of low dose aspirin (LDA) may substantially reduce the rate of PTB.
Methods: Hypothesis: LDA initiated in the first trimester reduces the risk of preterm birth. Study Design Type: Prospective randomized, placebo-controlled, double-blinded multi-national clinical trial conducted in seven low and middle income countries. Trial will be individually randomized with one-to-one ratio (intervention/control) Population: Nulliparous women between the ages of 14 and 40, with a …
