RESUMO

BACKGROUND: Even in developing countries like Nepal, prevalence of ST-elevation myocardial infarction has been shown to be increased with rise in prevalence of conventional risk factors like diabetes, Hypertension, smoking, dyslipidemia and obesity. Our aim is to retrospectively analyze for various risk factors and angiographic patterns of coronary artery disease in patients with ST-elevation myocardial infarction undergoing Primary Percutaneous Intervention. RESULTS: During the period of 1 year (January 2019 to December 2019), 816 patients presented to our ER with acute STEMI, among them 437 (53.6%) patients underwent primary PCI strategy and among them 22 (5.3%) patients were died. Thirty-six (4.4%) patients received thrombolysis, among them 5 (13.9%) patients were died while remaining 343 (42.0%) patients were managed conservatively and among them 20 (5.8%) were died. The mean age of patient who underwent primary PCI was 58.5±12.7 years range from 25 years to 99 years. Among them 55-75 years old 217 (49.6%) were highest in number followed by<55 years old 180 (41.2%). Males 318 (72.8%) were predominant. Among those who underwent primary PCI, hypertension 214 (49%) was the most common risk factor, followed by smoking 198 (45.3%), diabetes mellitus 123 (28.1%), dyslipidemia 53 (12.1%) and family history of premature coronary artery disease 18 (4.1%). Among those patients, 292 patients (66.8%) had single vessel disease, 99 patients (22.7%) had double vessel disease, 41 patients (9.3%) had triple vessel disease and 5 patients (1.1%) had non-significant coronary artery stenosis. Left anterior descending (53.3%) was the most frequently found culprit artery, followed by right coronary artery, left circumflex, ramus intermedius and left main artery. CONCLUSION: Fifty percent of patients presented with acute ST-elevation myocardial infarction and underwent primary PCI were between 55-75 years of age. Hypertension and smoking were the most common risk factors present in those patients. Single vessel disease was most prevalent with left anterior descending found to be the most commonly involved coronary artery followed by right coronary artery and left circumflex.

RESUMO

We report on a quantum electrodynamic (QED) investigation of the interaction between a ground state atom with another atom in an excited state. General expressions, applicable to any atom, are indicated for the long-range tails that are due to virtual resonant emission and absorption into and from vacuum modes whose frequency equals the transition frequency to available lower-lying atomic states. For identical atoms, one of which is in an excited state, we also discuss the mixing term that depends on the symmetry of the two-atom wave function (these evolve into either the gerade or the ungerade state for close approach), and we include all nonresonant states in our rigorous QED treatment. In order to illustrate the findings, we analyze the fine-structure resolved van der Waals interaction for nD-1S hydrogen interactions with n=8, 10, 12 and find surprisingly large numerical coefficients.

RESUMO

INTRODUCTION: Smoking, diabetes mellitus, hypertension, and dyslipidemia are labelled as conventional risk factors for coronary artery disease. Prevalence of these risk factors varies across populations. This study aimed to assess the prevalence of these conventional risk factors in patients, who were discharged from our hospital, with the diagnosis of ST elevation myocardial infarction. METHODS: Medical records of 495 ST elevation myocardial infarction patients discharged from our centre in between January 2012 to December 2012 were retrospectively reviewed to evaluate the prevalence of conventional risk factors. RESULTS: Clear dominance (75%) of male patients was seen. Inferior wall myocardial infarction (29.9%) was the most common diagnosis followed by anterior wall myocardial infarction (25.1%). Hypertension (65%), smoking (57.8%) and dyslipidemia (45.5%) were the most common risk factors. Diabetes (31.1%) was the least common. Prevalence of hypertension, dyslipidemia was similar among male and female. Smoking was statistically common in male (76.8%vs 49.5%),though diabetes was common in female (36.5%vs.29.3%) not statistically significant. CONCLUSIONS: Conventional risk factors are common among ST elevation myocardial infarction patients. Early detection and treatment of these risk factors play a vital role for the prevention of coronary artery disease. Much more focus should be stressed on preventive programs throughout the country.

RESUMO

BACKGROUND: The World Health Organization has declared tuberculosis a global emergency in 1993. It has been estimated that one third of the world population is infected with Mycobacterium tuberculosis, the causative agent of tuberculosis. The emergence of TB/HIV co-infection poses an additional challenge for the control of tuberculosis throughout the world. The World Health Organization is supporting many developing countries to eradicate tuberculosis. It is an agony that one fifth of the tuberculosis patients worldwide are in India. The eradication of tuberculosis is the greatest public health challenge for this developing country. The aim of the present population based study on Mycobacterium tuberculosis is to test a large set of tuberculosis cases for the presence of statistically significant geographical clusters. A spatial scan statistic is used to identify purely spatial and space-time clusters of tuberculosis. RESULTS: Significant (p < 0.05 for primary clusters and p < 0.1 for secondary clusters) high rate spatial and space-time clusters were identified in three areas of the district. CONCLUSION: There is sufficient evidence about the existence of statistically significant tuberculosis clusters in Almora district of Uttaranchal, India. The spatial scan statistics methodology used in this study has a potential use in surveillance of tuberculosis for detecting the true clusters of the disease.
