AIMS: The aim of this study was to establish the feasibility, and to investigate the impact, of community pharmacy-based educational intervention on knowledge, practice, and disease management of patients with hypertension in Western Nepal.
METHOD: A single-cohort pre-/post-intervention study was conducted from August 2012 to April 2013. The participants included in the study were patients diagnosed with hypertension attending a pharmacist-led hypertension clinic. The educational intervention was conducted by pharmacists, was individualised, and consisted of three counselling sessions over a period of six months. The patients' knowledge of hypertension, their practice of lifestyle modification and non-pharmacological approaches concerning hypertension management, and blood pressure were assessed at baseline and again after nine months by using a pre-validated questionnaire.
RESULTS: Fifty patients met the inclusion criteria and were enrolled in the study. The median (IQR) knowledge score changed from 6 (4) to 13 (0) after the intervention (p<0.01) with the median (IQR) practice score changing from 7 (4) to 16 (2) (p<0.01). The mean (SD) systolic BP changed from 150.1 (7.8) to 137.7 (9.9) (p<0.01) and the mean (SD) diastolic BP from 104 (9.5) to 94.5 (7.8) after the intervention (p< 0.01).
CONCLUSION: A simple, educational intervention by community pharmacists had improved patients' disease knowledge, practice, and management of their hypertension. Evidence suggests Nepalese community pharmacists need could play an important role in the management of chronic diseases like hypertension through simple interventions such as providing educational support for patients.
METHODS: Twenty-four male, 8-week old Sprague Dawley rats with an initial weight of 160 to 200 g were randomised into three groups (n = 6 for each group): groups A (standard rat chow), B (high-fat, high-sucrose diet), and C (high-fat, high-sucrose diet + 100 mg/kg/d of glycyrrhizic acid via oral administration). The rats were treated accordingly for 4 wk. Glycaemic parameters, lipid profile, stress hormones, and adiponectin levels were measured after the treatment. Relative gene expressions of peroxisome proliferator-activated receptor α and γ, lipoprotein lipase as well as gluconeogenic enzymatic activities in different tissues were also determined.
RESULTS: Consumption of high-fat, high-sucrose diet triggered hyperglycaemia, insulin resistance, and dyslipidemia, which were effectively attenuated by supplementation with glycyrrhizic acid. Glycyrrhizic acid supplementation also effectively reduced circulating adrenaline, alleviated gluconeogenic enzymes overactivity, and promoted the upregulation of lipoprotein lipase expression in the cardiomyocytes and skeletal muscles. A high calorie diet also triggered hypoadiponectinaemia and suppression of peroxisome proliferator-activated receptor γ expression, which did not improve with glycyrrhizic acid treatment.
CONCLUSION: Supplementation with glycyrrhizic acid could alleviate high calorie diet-induced glucose and lipid metabolic dysregulations by reducing circulatory stress hormones, normalizing gluconeogenic enzyme activities, and elevating muscular lipid uptake. The beneficial effects of these bioactivities outweighed the adverse effects caused by diet-induced repression of peroxisome proliferator-activated receptor γ expression, resulting in the maintenance of lipid and glucose homeostasis.
METHODS: In this prospective cohort study, we included 1,365 employees enrolled in the university's workplace health promotion program, a program conducted since 2008 and using data from the 2008-2013 follow-up period. Participants were permanent employees aged 35 years and above, with at least one follow up measurements and no change in antihypertensive medication during the study period. Baseline socio-demographic information was collected using a questionnaire while anthropometry measurements and resting blood pressure were collected during annual health screening. Changes in blood pressure over time were analyzed using a linear mixed model.
RESULTS: The systolic blood pressure in the hypertension subgroup decreased 2.36 mmHg per year (p<0.0001). There was also significant improvement in systolic blood pressure among the participants who were at risk of hypertension (-0.75 mmHg, p<0.001). The diastolic blood pressure among the hypertensive and at risk subgroups improved 1.76 mmHg/year (p<0.001) and 0.56 mmHg/year (p<0.001), respectively. However, there was no change in both systolic and diastolic blood pressure among participants in the healthy subgroup over the 6-year period.
CONCLUSION: This study shows that continuing participation in workplace health promotion program has the potential to improve blood pressure levels among employees.
