Background: Globally, 51% of stroke (cerebrovascular disease) and 45% of ischaemic heart disease deaths are attributable to high systolic blood pressure. At any given age, the risk of dying from high blood pressure in low- and middle-income countries is more than double that in high-income countries. The objective of the study was to know the prevalence of undiagnosed hypertension among rural population.Methods: A community based cross-sectional study conducted in villages under the rural field practice area of medical college in the month of May, 2017. 365 people participated in the hypertension screening camp constituted the study sample.Results: Prevalence of undiagnosed HTN was found to be 10.1% among study population. Nearly 58.1% of the people are with normal blood pressure while 31.2%, 10.7% of the study population are classified prehypertensive, hypertensives according to JNC- VII.Conclusions: Early detection and treatment of hypertension and other risk factors through Health education programs, public awareness campaigns to be conducted actively among population.

Background: Internet gaming disorder (IGD) refers to the problematic use of on-line or off-line video games.  Presently the prevalence of IGD among the adolescent group was between 1.3%  to 19.9% and males reported more prevalence than females. Aims of this study was to know the prevalence and the various factors associated with the development IGD among adolescents.Methods: Settings and Design was to a cross sectional study was conducted among students of High schools for a period of 3 months from July 2018 - September 2018. Four hundred adolescent students were included in the study. English version of the DSM–5 short (9-item) dichotomous scale with cut-off point of five or more criteria was used for diagnosing the IGD.Statistical analysis used descriptive statistics were represented with frequencies and percentages. Chi-square and Fisher Exact tests were applied to find significance difference. P<0.05 was considered as statistically significant.Results: An overall prevalence estimate of IGD was 3.50% among the school children and it is higher among male students (8.8%) than female students (0.8%) and it was found statistically significant with a p value of <0.001.Conclusions: The prevalence differences between Age groups, gender, class of the student and availability of smart phone with internet facility act as an important risk factors for the occurrence of IGD among adolescents.

Background: The rising prevalence overweight and obesity in India has a direct correlation with the increasing prevalence of obesity-related co-morbidities; hypertension, the metabolic syndrome, dyslipidemia, type 2 diabetes mellitus, and cardiovascular disease. The risk for these disorders appears to start from a body mass index (BMI) of about 21 kg/m2. The objective of the study was to know the prevalence of generalized and abdominal obesity in the field practice area.Methods: A community based cross-sectional study conducted among 309 people in the rural field practice area of medical college from January to March, 2017.Results: In the present study prevalence of generalized, abdominal and combined obesity was 56%, 71.2% and 51.3% respectively.Conclusions: Prevention of obesity should begin in early childhood. Obesity is harder to treat in adults than it is in children. The control of obesity centers on the weight reduction. Information Education and Communication (IEC), Behaviour change communication (BCC) is used to encourage individuals of the society to adopt healthy behaviours like dietary modifications, increased physical activity and a combination of both.

New alternative jet fuels have provided many advantages in the aviation industry, especially in terms of economics and environment. However, fuel–seal compatibility is one of the major issues that restricts alternative fuel advancement into the market. Thus, to help understand and solve the problem, this study examines the swelling effect of prepared and non-prepared O-rings in different fuels and aromatic species. Stress relaxation experiments were carried out to evaluate seal compatibility under compression, which mimics engine operation conditions. Seals were compressed and immersed in a variety of fuels and their blends for about 90h while maintaining a constant temperature 30°C and constant compression force of 25% seal thickness. The two types of elastomers investigated were fluorosilicone and nitrile O-rings, which are predominantly used in the aviation industry. Meanwhile, three different fuels and aromatic species were utilised as the variables in the experiments. The fuels used were Jet-A1, SPK and SHJFCS, while the aromatic species added were propyl benzene, tetralin and p-xylene. The swelling effects were determined from the P/Po value. Results indicate that Jet-A1 has the highest swelling effect, followed by SHJFCS and SPK. It was observed that the higher the percentage of aromatics in fuel, the higher the rate of swelling. Furthermore, prepared seals had a lower swelling rate than did non-prepared seals. Meanwhile, the intensity of the swelling effect in the Jet-A1-SHJFCS blends was in the order of 60/40, 85/15 and 50/50 blend. The work done in this study will aid in the selection of suitable aromatic species in future fuels. The novelty of this research lies in the determination of the appropriate amount of aromatic content as well as the selection of type of aromatic and its mixture fuel. Moreover, the various proportions of fuel blends with aromatic are investigated. The primary aim of this study is to understand the behaviour of prepared and non-prepared seals, and their compatibility with alternative fuels.
