Background: Road traffic injuries are the eighth leading cause of death globally, and the leading cause of death for young people aged 15–29 years. Each year, almost 400,000 young people under 25 years old are killed in a road traffic crash - about 1049 youngsters every day. Aims and objectives: To find out the prevalence of road safety related health risk behaviours and its determinants amongst young males of District Dehradun. Methodology: It was a cross sectional study conducted over 12 months of duration. The study sample comprised of 1800 male youth aged 15-24years studying in various schools and colleges of District Dehradun. A pre-tested and pre-structured questionnaire (YRBSS) was used. The data was entered and analysed using SPSS-version 20.0. Results: Approximately three-fourth of youth reported never using seat-belt while driving and only 4.4% reported always using helmet whereas 24.0% accepted never use of helmet. Approximately one-fourth of the total 1168 at risk subjects in past 30 days, accepted driving a vehicle while drunk and 39.9% reported use of mobile phones while driving. Personality traits (extrovert, neuroticism and lack of direction) turned out to be the major factor in road safety related health risk behaviour. Conclusion: Although, road safety related health risk was found to be more among urban youth as compared to their rural counterparts, yet it was found alarmingly high for both rural and urban study population.

Aims: The prevalence of premature coronary artery disease (CAD) in India is two to three times more than other ethnic groups. Untreated heterozygous familial hypercholesterolemia (FH) is one of the important causes for premature CAD. As the age advances, these patients without treatment have 100 times increased risk of cardiovascular (CV) mortality resulting from myocardial infarction (MI). Recent evidence suggests that one in 250 individuals may be affected by FH (nearly 40 million people globally). It is indicated that the true global prevalence of FH is underestimated. The true prevalence of FH in India remains unknown. Methods: A total of 635 patients with premature CAD were assessed for FH using the Dutch Lipid Clinical Network (DLCN) criteria. Based on scores, patients were diagnosed as definite, probable, possible, or no FH. Other CV risk factors known to cause CAD such as smoking, diabetes mellitus, and hypertension were also recorded. Results: Of total 635 patients, 25 (4%) were diagnosed as definite, 70 (11%) as probable, 238 (37%) as possible, and 302 (48%) without FH, suggesting the prevalence of potential (definite + probable) FH of about 15% in the North Indian population. FH is more common in younger patients, and they have lesser incidence of common CV risk factors such as diabetes, hypertension, and smoking than the younger MI patients without FH (26.32% vs.42.59%; 17.89% vs.29.44%; 22.11% vs.40.74%). Conclusion: FH prevalence is high among patients with premature CAD admitted to a cardiac unit. To detect patients with FH, routine screening with simple criteria such as family history of premature CAD combined with hypercholesterolemia, and a DLCN criteria score >5 may be effectively used.

Objective: Primary objective was to compare the effects of atorvastatin 40 mg vs 80 mg on LDL-C in Indian patients with atherosclerotic dyslipidemia. Secondary objectives were to compare the effects of atorvastatin 40 mg vs 80 mg on HDL-C and triglycerides and also comparing of side effects (myopathy, hepatotoxicity and new onset diabetes mellitus) of both doses. Method: This Study is A Prospective, randomized, open-label, comparative study. This study was conducted on 240 patients of dyslipidemia (as per ACC/AHA 2013 lipid guidelines) attending the OPD/wards/CCU of department of cardiology, Sir Ganga Ram Hospital. They were randomly divided into 2 groups of 120 each. Group A consisted patients who received Atorvastatin 40 mg daily and Group B Atorvastatin 80 mg daily. The follow up period was 6 months. Results: At 3 and 6 month follow up, Atorvastatin 40 mg leads to mean LDL cholesterol reduction of 47.18 ± 20.81 & 50.03 ± 18.06 respectively. While Atorvastatin 80 mg results in LDL reduction as 50.11 ± 15.85 & 52.30 ± 13.72. The comparison between two doses revealed a non-significant difference (p = .118 & p = .149 respectively).At 6 months of follow up, few patients reported myalgia (2 in group A and 7 in Group B). The difference between groups was significant (p = .045). Although none of our patient had significant elevation of CPK. Conclusion: This study concluded that both doses of atorvastatin (40 & 80 mg) are equally efficacious in improving dyslipidemia but higher dose leads to more incidence of myalgia.

Small dense (sd) LDL is a significant independent risk factor for premature coronary artery disease (CAD). Unfortunately, its estimation is not popular, due to the limited availability of specialized equipment, high cost and time-consuming technique. Non-HDL is a calculated, single index measure of all atherogenic apolipoprotein-B containing lipoproteins. This study aimed at identifying non-HDL as a superior surrogate marker of sdLDL cholesterol in a young Indian population. 161 healthy subjects

The choice of drug-eluting stent in the treatment of patients with diabetes mellitus and coronary artery disease who are undergoing percutaneous coronary intervention (PCI) has been debated. Previous studies comparing paclitaxel-eluting stents with stents eluting rapamycin (now called sirolimus) or its analogues (everolimus or zotarolimus) have produced contradictory results, ranging from equivalence between stent types to superiority of everolimus-eluting stents.We randomly assigned 1830 patients with diabetes mellitus and coronary artery disease who were undergoing PCI to receive either a paclitaxel-eluting stent or an everolimus-eluting stent. We used a noninferiority trial design with a noninferiority margin of 4 percentage points for the upper boundary of the 95% confidence interval of the risk difference. The primary end point was target-vessel failure, which was defined as a composite of cardiac death, target-vessel myocardial infarction, or ischemia-driven target-vessel revascularization at the 1-year follow-up.At 1 year, paclitaxel-eluting stents did not meet the criterion for noninferiority to everolimus-eluting stents with respect to the primary end point (rate of target-vessel failure, 5.6% vs. 2.9%; risk difference, 2.7 percentage points [95% confidence interval, 0.8 to 4.5]; relative risk, 1.89 [95% confidence interval, 1.20 to 2.99]; P=0.38 for noninferiority). There was a significantly higher 1-year rate in the paclitaxel-eluting stent group than in the everolimus-eluting stent group of target-vessel failure (P=0.005), spontaneous myocardial infarction (3.2% vs. 1.2%, P=0.004), stent thrombosis (2.1% vs. 0.4%, P=0.002), target-vessel revascularization (3.4% vs. 1.2%, P=0.002), and target-lesion revascularization (3.4% vs. 1.2%, P=0.002).In patients with diabetes mellitus and coronary artery disease undergoing PCI, paclitaxel-eluting stents were not shown to be noninferior to everolimus-eluting stents, and they resulted in higher rates of target-vessel failure, myocardial infarction, stent thrombosis, and target-vessel revascularization at 1 year.

Extracting minutiae from fingerprint images is one of the most important steps in automatic fingerprint identification and classification. Minutiae are local discontinuities in the fingerprint pattern, mainly terminations and bifurcations. In this work we have propose a method for fingerprint image enhancement. Using histogram equalization over filtering and then minutia are calculated. The results achieved are compared with those obtained through some other methods. The Results show some improvement in the minutiae extraction in terms of quantity.

Coronary artery disease (CAD) affects Indians 5–6 years earlier than in the west, is diffuse and malignant, and poses a heavy burden on India’s developing economy. Traditional risk factors have failed to explain this high incidence of premature CAD and hence this study investigated the association of two novel risk biomarkers, cystatin C and small dense LDL (sdLDL) with the presence and severity of CAD. Cystatin C and sdLDL were estimated in 204 CAD patients ≤45 years of age and compared with 161 age-matched healthy controls. The traditional lipid profile parameters, i.e., cholesterol, LDL, HDL, triglycerides, apolipoproteins A1 and B, and Lp(a) were also measured in both groups. Cystatin C was significantly raised and mean LDL particle size significantly reduced in CAD patients as compared to controls. 62.7 % of CAD patients showed pattern B while 37.3 % patients showed pattern A. Of the traditional lipid tests, only HDL and apolipoprotein A1 showed a significant decrease in the CAD group. sdLDL was significantly associated with the severity of CAD, while cystatin C was not. Both cystatin C and sdLDL emerged as independent risk factors, however, of the two, sdLDL was a more sensitive predictor of CAD events. Cystatin C and mean LDL particle size are significantly and independently associated with the presence of CAD events in patients ≤45 years with normal kidney function. Hence, these novel risk biomarkers can be useful tools in reducing the morbidity and mortality associated with CAD in the productive Indian workforce.

The left internal mammary artery is frequently employed as a conduit in coronary bypass surgery. We report a 42-year-old male post-coronary artery bypass grafting patient with, angina on exertion who was found to have multiple atrioventricular fistulae arising from left internal mammary artery to pulmonary vasculature leading to coronary steal and positive stress thallium in left anterior descending territory. These fistulae were selectively embolized with polymer particles leading to improved flow in distal left anterior descending artery. Postintervention, the patient has been asymptomatic for more than 8 months.
