METHODS: Orchidectomized adult male Sprague-Dawley (SD) rats received seven days subcutaneous testosterone treatment (125 μg/kg/day or 250 μg/kg/day), with or without flutamide or finasteride. Following completion of treatment, MAP was determined in rats under anaesthesia via carotid artery cannulation. In another cohort of rats, kidneys were removed following sacrifice and AQP-1, 2, 3, 4, 6 and 7 protein and mRNA levels were determined by Western blotting and Real-time PCR respectively. Distribution of AQP subunits' protein in the nephrons were visualized by immunofluorescence.
RESULTS: Testosterone caused MAP, AQP-1, 2, 4, 6 and 7 protein and mRNA levels in kidneys to increase while AQP-3 protein and mRNA levels in kidneys to decrease (p blood pressure.
METHODS: An analytical cross-sectional study was conducted in a government health clinic of Penang from March to August 2019. Asymptomatic clinic attendees aged 50-75 years who had no prior awareness of CRC screening were recruited by systematic random sampling technique. Participants first received a standardised one to one health education, followed by an interview using a standardised questionnaire to assess their CRC screening intention and the relevant motivators and barriers. A submission of a sample for immunochemical faecal occult blood test (iFOBT) was considered as an uptake of the CRC screening.
RESULTS: A total of 546 participants participated in this study. The mean age of the participants was 62.8 (SD=6.36). Majority of them were females (57.3%), Chinese (78.6%), who had attained primary or higher education (92.0%) and had comorbidities (87.0%). After a brief health education, 231 participants (42.3%) agreed to undergo iFOBT. The actual screening uptake rate in this study was 28%. Perceived benefit of the test (84.4%) was the most common motivators, while self-perceived non-vulnerability was the biggest impediment to CRC screening intention. Physicians' recommendation was the perceived most effective way in raising CRC awareness.
CONCLUSION: Participants prefer physicians to provide health education. Standardised brief health education is inadequate to stimulate CRC screening adherence. Future interventions will require in-depth understanding of patients' beliefs, risk perception, and affective responses.
METHODS: A cluster-randomized controlled trial was conducted with schools as clusters over a period of six-months with pre and post intervention evaluations. Participants were public secondary school students (14-19 years) from four schools in Brong Ahafo, Ghana. Students in the intervention group were trained by the researchers whereas those of the control group received no intervention. The intervention included health education and physical activity modules. Follow-up data using same questionnaire were collected within two weeks after the intervention was completed. Intention-to-treat analysis was performed after replacing missing values using the multiple imputation method. The generalized linear mixed model (GLMM) was used to assess the effects of the intervention study.
RESULTS: The GLMM analyses showed the intervention was effective in attaining 0.77(p<0.001), 0.72(p<0.001), 0.47(p<0.001), 0.56(p<0.001), and 0.39(p = 0.045) higher total physical activity, fruits, vegetables, seafood, and water scores respectively for the intervention group over the control group. The intervention was also significant in reducing -0.15(p<0.001),-0.23(p<0.001),-0.50(p<0.001),-0.32(p<0.001),-0.90(p<0.001),-0.87(p<0.001),-0.38(p<0.001), -0.63(p<0.001), -1.63(p<0.001), 0.61(p<0.001), and -1.53(p = 0.005) carbohydrates, fats and oils, fried eggs, fried chicken, carbonated drinks, sugar, sweet snacks, salted fish, weight, BMI, and diastolic BP. The odds of quitting alcohol use in the intervention group were 1.06 times more than the control group. There was no significant effect on reducing smoking and systolic BP.
CONCLUSION: There is an urgent need for the intervention program to be integrated into the existing curriculum structure of secondary school schools. Implementing the intervention will allow for longer and more consistent impact on the reduction of CVD risk factors among secondary school students.
