OBJECTIVE: To provide an overview and identify the present landscape of hemp research topics, trends, and gaps.
METHODS: A systematic search and analysis strategy according to the preferred reporting items for systematic review and meta-analysis-ScR (PRISMA-ScR) checklist on electronic databases including MEDLINE, OVID (OVFT, APC Journal Club, EBM Reviews), Cochrane Library Central and Clinicaltrials.gov was conducted to include and analyse hemp research articles from 2009 to 2019.
RESULTS: 65 primary articles (18 clinical, 47 pre-clinical) were reviewed. Several randomised controlled trials showed hempseed pills (in Traditional Chinese Medicine formulation MaZiRenWan) improving spontaneous bowel movement in functional constipation. There was also evidence suggesting benefits in cannabis dependence, epilepsy, and anxiety disorders. Pre-clinically, hemp derivatives showed potential anti-oxidative, anti-hypertensive, anti-inflammatory, anti-diabetic, anti-neuroinflammatory, anti-arthritic, anti-acne, and anti-microbial activities. Renal protective effects and estrogenic properties were also exhibited in vitro.
CONCLUSION: Current evidence on hemp-specific interventions are still preliminary, with limited high quality clinical evidence for any specific therapeutic indication. This is mainly due to the wide variation in test item formulation, as the multiple variants of this plant differ in their phytochemical and bioactive compounds. Future empirical research should focus on standardising the hemp plant for pharmaceutical use, and uniformity in experimental designs to strengthen the premise of using hemp in medicine.
OBJECTIVES: To determine the self-esteem among oncology patients receiving chemotherapy in selected government state hospitals, Peninsular Malaysia.
METHODS: A cross-sectional study was conducted using selfadministered questionnaires. 953 respondents were given questionnaires which included socio-demographic profile, physical effect, depression, anxiety, quality of life and self esteem. Inferential analysis was done by using Independent T-test or Pearson's Correlation and the level of significance was p<0.05. Multivariate logistic regression was then used to determine the predictors using Statistical Package for Social Sciences software version 22.0 RESULTS: All 953 respondents selected participated in this study. The overall mean self-esteem in this study was 22.67, SD=4.98. The significant predictors of self-esteem where pvalue was <0.05 were age; gender; marital status; working status; anxiety; depression; nausea; anemia; hair loss; skin and nail changes; overall quality of life and psychological domain of quality of life. The finding of this study indicates that predictors of selfesteem among patients undergoing chemotherapy should be taken into account to improve their quality of life. Guidelines on how to manage self-esteem in a chemotherapy patient can be done using this study as the baseline.
OBJECTIVES: To determine the prevalence and predictors of poor sleep quality among secondary school students in Gombak District, Selangor.
METHODS: A cross-sectional study was conducted in Gombak District. The sample size was 1,092 based on two group comparison formula. Students were selected using sampling with probability to proportionate to size. Selfadministered pretested questionnaires were used to collect the data. The data were analysed using the Statistical Package for Social Sciences (SPSS) version 22. Chi-square or Fisher's exact test was performed to determine the association between individual categorical variables and sleep quality. Variables with p-value <0.25 were selected to be subjected into multivariate logistic regression to determine the predictors.
RESULTS: The response rate was 93.0%. The prevalence of poor sleep quality was 24.0% (95% CI = 21.5, 26.6). Based on the analysis of simple logistic regression seven variables that were significantly associated with poor sleep quality were age, gender, marital status of parents, depression, anxiety, stress and academic performance found fit in the model. Multivariate logistic analysis showed that the significant predictors of poor sleep quality were age, marital status of parents, depression, anxiety, stress and academic performance. Factors that were not statistically significant were gender, religion, ethnicity, parent's educational level and family income.
CONCLUSIONS: Prevalence of poor sleep quality among adolescents is high. The predictors of poor sleep quality are age, marital status of parents, depression, anxiety, stress and academic performance.
Methods: We utilised 2,179 referrals between January and December 2015 from six general hospitals and three mental health institutions that provide clinical psychology services.
Results: The percentage of male referrals (60.3%) is higher than that of female referrals (39.7%). Adult cases had the highest percentage of referrals (48.2%). Children (48.8%) and adolescent (28.1%) cases were mainly referred for psychological assessment. Meanwhile, adult cases (74.8%) were mainly referred for psychological intervention. Neurodevelopmental disorders was the diagnosis with the highest percentage of referrals recorded (41.4%), followed by depressive disorders (13.3%) and anxiety disorders (12.7%), and the combination of other disorders. Psychiatrists provided the highest number of referrals (82.2%), which is unsurprising as both fields are closely related.
Conclusion: Clinical psychology services within the Ministry of Health (MOH) Malaysia play an important role in mental health care.
