Prevalence and Risk Factors of Hypertension Among Male Police Personnel in Urban Puducherry, India.

BACKGROUND: Hypertension is an important health issue among high risk occupation groups like police personnel. OBJECTIVE: To assess the prevalence and risk factors of hypertension among male police personnel. Method This cross sectional study was conducted among male police personnel residing in urban Puducherry, India. Data on blood pressure (BP), anthropometric measurements, demographic factors, smoking, alcohol intake, physical activity, stress level, obesity and dietary factors were collected by interview technique using a standard questionnaire. RESULT: About 296 police personnel were participated. Most of them belonged to the age group of 25-39 years (68%). The prevalence of pre-hypertension and hypertension was 37.8% and 34.5% respectively. Among those with hypertension, 56.86% (58/102) were known hypertensives and 43.13% (44/102) were newly diagnosed. Age group of 50-59 years (AOR=8.472) and 40-49 years (AOR=8.15), currently using alcohol (AOR=1.797), less than 7 servings of fruits in a week (AOR=3.228), moderate stress level (AOR=2.374) and waist circumference more than 90 cm (AOR=4.937) were associated with higher prevalence of hypertension among police personnel. CONCLUSION: Hypertension among Police personnel is comparatively higher than general population in this area. Reduction in alcohol use, increase in fruit servings along with other lifestyle modification measures may help in prevention and control of hypertension.

Linking bone marrow fat with decreased bone mineral density among Indian patients with osteoporotic fracture.

Osteoporosis is a systemic skeletal disorder with low-bone mass causing micro-architectural deterioration and an increase in bone fragility and susceptibility to fractures. According to a worldwide report by IOF, 1 in 3 females and 1 in 5 males will experience fractures due to the osteoporotic changes in their bones. Fractures may be the first clinical manifestation of the disease. They have been causes for morbidity and mortality imposing economic burden to osteoporosis. Bone marrow fat is a negative regulator of bone-turnover and a key integrator of bone and energy metabolism. Hence we assess the bone marrow fat and BMD in patients with osteoporotic bone fractures. This cross-sectional study was conducted in 30 patients from the department of orthopaedic surgery. Biopsy samples were received from excised bone during surgery. Biochemical parameters and bone marrow fat were quantified by established methods. A negative correlation between BMD versus serum adiponectin, FGF21 and similar observation with BMD versus bone marrow fat is seen. Therefore, increased bone-marrow fat and adiponectin, FGF21 levels and decreased BMD in osteoporosis. This observation might be useful for prevention, management and therapeutic potential of osteoporosis. Based on our study findings, understand the bone-fat relationship to implications with low BMD in patients with osteoporosis.

Serum sclerostin levels as a diagnostic marker for osteoporosis.

Osteoporosis is asymptomatic, in which low bone-mass and micro-architectural deterioration of bone tissue leads to increasing bone fragility and fracture. Vertebral and hip fractures lead to increased mortality, resulting in enormous health care costs. BMD testing by DEXA is used in diagnosis of osteoporosis. However, low-and middle-income populations are unable to conduct periodic examinations of bone mineral status. Thus, current study is mainly aimed at finding a cost-effective diagnostic-marker for osteoporosis. 170 participants, of whom 51 had osteoporosis, 62 had osteopenia and 57 had normal bone-mass. Selection of individuals was based on DEXA scan BMD. Sclerostin was determined by ELISA. The variables were compared using ANOVA test and ROC analysis was performed. Sclerostin levels were significantly decreased in osteoporosis (4.62 ± 1.6 ng/mL) and osteopenia (4.92 ± 1.4 ng/mL) compared with controls (5.74 ± 1.3 ng/mL), (p < 0.0001). Sclerostin level 5.6 ng/mL is the cut-off value for diagnostic purpose, according to good sensitivity and specificity. In patients with osteopenia and osteoporosis, decreased sclerostin levels were associated with an increased disease risk. These relationships were independent of BMD and bone turnover, suggesting that Sclerostin levels may reflect disease-severity in osteoporosis. Sclerostin measurements could become a useful clinical index for diagnosis of osteoporosis.

Multi-target potential of Indian phytochemicals against SARS-CoV-2: A docking, molecular dynamics and MM-GBSA approach extended to Omicron B.1.1.529.

BACKGROUND: SARS-CoV-2, an emerged strain of corona virus family became almost serious health concern worldwide. Despite vaccines availability, reports suggest the occurrence of SARS-CoV-2 infection even in a vaccinated population. With frequent evolution and expected multiple COVID-19 waves, improved preventive, diagnostic, and treatment measures are required. In recent times, phytochemicals have gained attention due to their therapeutic characteristics and are suggested as alternative and complementary treatments for infectious diseases. This present study aimed to identify potential inhibitors against reported protein targets of SARS-CoV-2. METHODOLOGY: We computationally investigated potential SARS-CoV-2 protein targets from the literature and collected druggable phytochemicals from Indian Medicinal Plants, Phytochemistry and Therapeutics (IMPPAT) database. Further, we implemented a systematic workflow of molecular docking, dynamic simulations and generalized born surface area free-energy calculations (MM-GBSA). RESULTS: Extensive literature search and assessment of 1508 articles identifies 13 potential SARS-CoV-2 protein targets. We screened 501 druggable phytochemicals with proven biological activities. Analysis of 6513(501 *13) docked phytochemicals complex, 26 were efficient against SARS-CoV-2. Amongst, 4,8-dihydroxysesamin and arboreal from Gmelina arborea were ranked potential against most of the targets with binding energy ranging between - 10.7 to - 8.2 kcal/mol. Additionally, comparative docking with known drugs such as arbidol (-6.6 to -5.1 kcal/mol), favipiravir (-5.5 to -4.5 kcal/mol), hydroxychloroquine (-6.5 to -5.1 kcal/mol), and remedesivir (-8.0 to -5.3 kcal/mol) revealed equal/less affinity than 4,8-dihydroxysesamin and arboreal. Interestingly, the nucleocapsid target was found commonly inhibited by 4,8-dihydroxysesamin and arboreal. Molecular dynamic simulation and Molecular mechanics generalized born surface area (MM-GBSA)calculations reflect that both the compounds possess high inhibiting potential against SARS-CoV-2 including the recently emerged Omicron variant (B.1.1.529). CONCLUSION: Overall our study imparts the usage of phytochemicals as antiviral agents for SARS-CoV-2 infection. Additional in vitro and in vivo testing of these phytochemicals is required to confirm their potency.

Epidemiology of disability in a rural community of Karnataka.

OBJECTIVES: To determine the prevalence and pattern of disability in all age groups in a rural community of Karnataka. METHODS: A community-based cross-sectional study was conducted during January-December 2004 among 1000 study subjects of all age groups selected randomly from four villages under rural field practice area of a teaching institution. Subjects were interviewed and examined using a predesigned schedule. Percentage prevalence, chi square test and multiple logistic regression analysis were used for statistical analysis. RESULTS: The prevalence of disability was found to be 6.3%. Both physical and mental disabilities are of great concern in this area. 80% of the disabled had multiple disabilities. Knowledge and occupation plays a major role as determinants of disability. Chronic medical conditions are also more common among disabled.
