Conducting tobacco control surveys among schoolchildren in Bangladesh, India and Pakistan: A feasibility study.

Most of the world's 300 million smokeless tobacco (ST) users live in South Asia but ST policies for that region are poorly researched, developed and implemented. Longitudinal studies to understand the uptake and use of ST and smoking, and influences on these, such as health promotion strategies, are lacking. We planned to conduct longitudinal surveys among secondary school students in three countries with the highest ST burden: Bangladesh, India and Pakistan to explore ST and smoking uptake, use and health promoting strategies.

A scoping review of the outcome reporting following surgery for chronic osteomyelitis of the lower limb.

Chronic osteomyelitis (COM) of the lower limb in adults can be surgically managed by either limb reconstruction or amputation. This scoping review aims to map the outcomes used in studies surgically managing COM in order to aid future development of a core outcome set. A total of 11 databases were searched.

Association of Diabetes With Lower Back Pain: A Narrative Review.

Diabetes mellitus with its increasing prevalence is one of the four major non-communicable diseases. It is characterized by hyperglycemia, which may progress to chronic complications such as peripheral vascular disease and neuropathy. This paper highlights the pathophysiology associated with diabetes, which is restricted to not only hyperglycemia but also other comorbidities including chronic lower back pain.

Influence of intrauterine growth status on aortic intima-media thickness and aortic diameter in near-term fetuses: a comparative cross-sectional study.

Intrauterine undernutrition may lead to fetal vascular programming. We compared abdominal aortic intima-media thickness (aIMT) and aortic diameter (aD) between appropriate for gestational age (AGA) and growth-restricted fetuses (GRF). We recruited 136 singleton fetuses at 34-37 weeks of gestation from Fetal Medicine Unit of Aga Khan University Hospital, Karachi (January-November 2017).

Major adverse cardiovascular events in patients undergoing percutaneous coronary intervention or coronary artery bypass graft with underlying chronic kidney disease.

Objective: To assess early and late outcome in severe chronic kidney disease patients undergoing revascularisation.

Methods: The retrospective ambi-directional cohort study was conducted at Tabba Heart Institute, Karachi, and comprised data from May, 2012, to July,2016, related to severe chronic kidney disease patients with creatinine clearance <30ml/min or end-stage renal disease on haemodialysis who had undergone coronary artery bypass graft / percutaneous coronary intervention. Early outcome was in-hospital major adverse cardiac event, like mortality, stroke and new haemodialysis.

Protocol for a feasibility study of longitudinal surveys to assess the impact of policies on tobacco use among school-going adolescents in South Asia.

Smokeless tobacco (ST) use is common among youth in South Asia where 85% of the world's 300 million ST users live and use the most lethal ST forms. Little is known about the impact of tobacco control policies on the youth ST uptake in those countries. We planned to conduct longitudinal surveys among school going adolescents to evaluate existing tobacco control policies on tobacco uptake and use, and a feasibility study for that prospective, observational cohort study.

Compliance of smokeless tobacco supply chain actors and products with tobacco control laws in Bangladesh, India and Pakistan: protocol for a multicentre sequential mixed-methods study.

Introduction: South Asia is home to more than 300 million smokeless tobacco (ST) users. Bangladesh, India and Pakistan as signatories to the Framework Convention for Tobacco Control (FCTC) have developed policies aimed at curbing the use of tobacco. The objective of this study is to assess the compliance of ST point-of-sale (POS) vendors and the supply chain with the articles of the FCTC and specifically with national tobacco control laws.

Clinical characteristics and in-hospital outcome in percutaneous coronary interventions with ST elevation myocardial infarction patients developing acute kidney injury.

Objective: To find predictors, incidence and hospital mortality of acute kidney injury in ST elevation myocardial infarction patients undergoing percutaneous coronary interventions.

Methods: The retrospective cross-sectional study was conducted at Tabba Heart Institute Karachi, and comprised data from June 2013 to December 2017 of ST elevation myocardial infarction patients undergoing percutaneous coronary interventions during index admission. Acute kidney injury was defined as serum creatinine ≥0.

In-hospital management and intermediate term outcomes in stable patients with ST segment elevation myocardial infarction presenting between 12-48 hours of symptom onset versus 2-7 days after the onset of chest pain; a single center study.

Objective: To evaluate hospital management, revascularisation and intermediate-term major adverse cardiac events amongst ST elevation myocardial infarction patients and to compare them in early and late presentations. .

Methods: The retrospective study was conducted at Tabba Heart Institute, Karachi, and comprised data from July 2013 to December 2016.

Mortality and deciding factors for no revascularization in cardiogenic shock patients; a cross sectional study.

Objective: To assess the frequency of acute coronary syndrome patients with cardiogenic shock and not undergoing revascularisation, their in- hospital outcome and reasons underlying management decisions.

Methods: The retrospective cross-sectional study was conducted at Tabba Heart Institute, Karachi, and comprised data from July 2013 to December 2017 of acute coronary syndrome with hypotension and not having under gone revascularisation. Data was analyzed using Stata 12.

Management, hospital outcome and revascularization trends in non-ST elevation myocardial infarction with high GRACE risk score.

Objective: To assess clinical characteristics, management strategies and in-hospital outcome among high-risk patients of non-ST elevation myocardial infarction.

Methods: The retrospective cross-sectional study was conducted at Tabba Heart Institute, Karachi, and comprised data from July 2013 to December 2016 of adult non-ST elevation myocardial infarction patients who had first cardiac event having Global Registry of Acute Coronary Eventsrisk score>140. Subcategories were formed on the basis of score range 140-159, 160-189 and ?190.

In-Hospital outcomes in acute coronary syndrome patients with concomitant severe chronic kidney disease undergoing percutaneous coronary intervention.

Objective: To determine in-hospital mortality and major adverse cardiac events (MACE) in acute coronary syndrome (AMI) patients with underlying severe chronic kidney disease (CKD) undergoing percutaneous coronary intervention (PCI).

Methods: We conducted a retrospective cohort study from June'2013-December'2017 at Tabba Heart Institute, Karachi. Data was drawn from institutes' database modeled after US National Cardiovascular data CathPCI registry.
