METHODS: The fruit powder was macerated using methanol and then partitioned by hexane, ethyl acetate, n-butanol, and water. The fractions were chromatographed on the column chromatography and incorporated with TLC and recrystallization to give pure compounds. The structures of isolated compounds were determined by UV-Visible, FT-IR, MS, proton (1H-NMR), carbon (13C-NMR), and 2D-NMR techniques encompassing HMQC and HMBC spectra. The compounds were evaluated for their ACE inhibitory activity, and the strongest compound was determined by the kinetics enzyme inhibition.
RESULTS: Based on the spectral data, the isolated compounds were determined as 6,4-dihydroxy-4-methoxybenzophenone-2-O-β-D-glucopyranoside (1), 4,4'-dihydroxy-6-methoxybenzophenone-2-O-β-D-glucopyranoside (2) and mangiferin (3). IC50 values of the isolated compounds 1, 2 and 3 were 0.055, 0.07, and 0.025 mM, respectively.
CONCLUSION: The three compounds have ACE inhibitor and mangiferin demonstrated the best ACE inhibitory activity with competitive inhibition on ACE with the type of inhibition kinetics is competitive inhibition.
METHODS: A total of 261 university students were recruited. Sociodemographic and anthropometric data were collected. Dietary intake was assessed using PLifeCOVID-19 questionnaire, sleep quality was assessed using Pittsburgh Sleep Quality Index Questionnaire (PSQI) while physical activity level was assessed using International Physical Activity Questionnaire-Short Forms (IPAQ-SF). SPSS was used to perform statistical analysis.
RESULTS: 30.7% of the participants adhered to the unhealthy dietary pattern, 48.7% had poor quality of sleep and 59.4% engaged in low physical activity levels during the pandemic. Unhealthy dietary pattern was significantly associated with a lower IPAQ category (p=0.013), and increased time spent sitting (p=0.027) during the pandemic. Participants being underweight before the pandemic (aOR=2.472, 95% CI=1.358-4.499), increased takeaway meal consumption (aOR=1.899, 95% CI=1.042-3.461), increased snacking between meals consumption (aOR=2.989, 95% CI=1.653-5.404) and engaged in a low level of physical activity during pandemic (aOR=1.935, 95% CI=1.028-3.643) were the predictors of unhealthy dietary pattern.
CONCLUSIONS: The university students' dietary intake, sleeping patterns, and physical activity levels were impacted in different ways during the pandemic. Strategies and interventions should be developed and implemented to improve the dietary intake and lifestyle of the students.
METHODS: Six bibliographic databases were searched from their respective inception to 31 December 2021. Data were pooled using random-effects meta-analysis.
RESULTS: Of 5476 identified articles, 15 satisfied the inclusion criteria with a total sample size of 38 618 patients. Pooled findings showed that individuals with cytomegalovirus infection had a higher risk of tuberculosis disease compared to those not infected with cytomegalovirus (odds ratio [OR], 3.20; 95% confidence interval [CI], 2.18-4.70). Age was the only covariate that exerted a significant effect on the result of the association. Meta-analysis of risk estimates reported in individual studies showed a marked and significant correlation of cytomegalovirus infection with active tuberculosis (adjusted hazard ratio, 2.92; 95% CI, 1.34-4.51; adjusted OR, 1.14; 95% CI, .71-1.57). A clear dose-response relation was inferred between the levels of cytomegalovirus antibodies and the risks of tuberculosis events (OR for high levels of cytomegalovirus antibodies, 4.07; OR for medium levels of cytomegalovirus antibodies, 3.58).
CONCLUSIONS: The results suggest an elevated risk of tuberculosis disease among individuals with a prior cytomegalovirus infection.
METHODS: This multinational cross-sectional survey was conducted in rehabilitation facilities in Malaysia, Indonesia, and Thailand. Community-dwelling adults with traumatic or nontraumatic spinal cord injury participating in the International Spinal Cord Injury Community Survey from 2017 to 2018 were enrolled. Data regarding bladder management/care, presence of bladder dysfunction, urinary tract infection, and quality of life score were extracted from the International Spinal Cord Injury Community Survey questionnaire. The impact of bladder care and urinary complications on quality of life was determined using univariable and multivariable regression analysis.
RESULTS: Questionnaires from 770 adults were recruited for analysis. After adjusting for all demographic and spinal cord injury-related data, secondary conditions, as well as activity and participation factors, urinary tract infection was an independent negative predictive factor of quality of life score ( P = 0.007, unstandardized coefficients = -4.563, multivariable linear regression analysis, enter method).
CONCLUSIONS: Among bladder care and urinary complication factors, urinary tract infection is the only factor negatively impacting quality of life. These results address the importance of proper bladder management and urinary tract infection prevention in persons with spinal cord injury to improve their quality of life.
