ABSTRACT
Exercise-Induced Bronchoconstriction (EIB) is a transient acute narrowing of the airway which occurs as a result of exercise. EIB is common in children. The prevalence of EIB has been estimated to be 20% in general individuals without a known diagnosis of asthma. Eighty percent of all asthma individuals experience exercise-related symptoms (ERS). The purpose of this study was to investigate the prevalence of EIB in medical students using an exercise challenge test. Aims And Objectives – To study the prevalence of prevalence of EIB in medical student and to investigate the relationship between EIB and the history of asthma, history of ERS, allergy including rhinitis, atopic dermatitis, hay fever, allergies to food and animals. Methods: This study was done on medical student of NMCH, Jamuhar between January 2019 and March 2019. Medical students underwent exercise challenge test on bicycle -ergometry. Spirometry was performed a few minutes before and immediately after performance of the exercise. The criterion for a positive test was a greater than 10% decrease in FEV1 from the baseline measurement. Results: Total 188 students completed the study, out of which 24 came to be EIB positive. 17 had history of asthma of which 15 came to be EIB positive. 13 had history of ERS of which 11 came to be EIB positive. Conclusion: In our study prevalence of EIB came to be 12.7%. EIB in student having history of asthma came to be 88.2%. EIB in student having history of ERS came to be 84.6%.
ABSTRACT
Background: Cardiovascular diseases are the most common diagnosis in the elderly, and the first cause of death in men and women over 60 years. It is not clear if the risk factors of acute myocardial infarction (AMI) are different in elderly and non-elderly people. The aim of this study was to compare the prevalence of risk factors of acute myocardial infarction between elderly and non-elderly patients who had been admitted to hospital for the first attack of acute myocardial infarction (AMI).Methods: A retrospective study was done in Narayan Medical College and Hospital, Jamuhar, Sasaram, Bihar from January 2017 to December 2017. Study population were all patients who were admitted due to AMI in medicine ward. Patients were selected as per World Health Organization guidelines. The patients were divided into two groups, non-elderly patients of <60 years and elderly patients of ≥60 years.Results: Among different risk factors, diabetes and hypertension were more common in elderly than their non-elderly counterparts, and male gender, smoking and family history of ischemic heart disease was more common in non-elderly patients than elderly ones.Conclusions: This study provide vital information on young AMI patients amongst the diverse population of north India and will help to guide the treating physicians and the health care system to adopt appropriate steps directed towards primary and secondary prevention of AMI in young patients of this region, especially smoking cessation, which is the commonest modifiable risk factor, in their most productive years of life.
