Controlled-release oral melatonin supplementation for hypertension and nocturnal hypertension: A systematic review and meta-analysis.

Oral melatonin is a potential alternative treatment for hypertension and nocturnal hypertension. However, high-quality and relevant meta-analyses are lacking. This meta-analysis aimed to investigate whether oral melatonin supplementation reduces daytime/asleep blood pressure and cardiovascular risk, improves sleep quality, and is well-tolerated compared with placebo. Relevant articles were searched in multiple databases, including MEDLINE, EMBASE, CINAHL Complete, and the Cochrane Library, from their inception to June 2021. The included studies were randomized controlled trials recruiting patients with hypertension, using oral melatonin as the sole intervention, and investigating its effect on blood pressure. The mean out-of-office (including 24-h, daytime, and asleep) systolic and diastolic blood pressures, sleep quality, and side effects were compared between the melatonin and placebo arms using pairwise random-effect meta-analyses. A risk of bias assessment was performed using the Cochrane risk-of-bias tool. Four studies were included in the analysis and only one study was considered to have a low risk of bias. No study reported on cardiovascular risk or outcomes. Only controlled-release melatonin (not an immediate-release preparation) reduced asleep systolic blood pressure by 3.57 mm Hg (95% confidence interval: -7.88 to .73; I2  = 0%). It also reduced asleep and awake diastolic blood pressure, but these differences were not statistically significant. Melatonin improves sleep efficacy and total sleep time and is safe and well-tolerated. Due to the limited number of high-quality trials, the quality of evidence was low to very low. Therefore, adequately powered randomized controlled trials on melatonin are warranted.

Fostering gerontology students' competence in Interprofessional collaborative practice.

BACKGROUND: Interprofessional collaborative practice (IPCP) is increasingly recognised as being crucial for the provision of holistic care and optimising health outcomes among older adults, many with multiple complex health problems. However, little is known about the challenges of facilitating this in practice. Therefore, this study explores these issues from the perspective of different healthcare professionals and how this might inform interprofessional education curricula. METHODS: Sixteen different healthcare professionals working in a variety of aged care (acute, rehabilitative and community) settings were invited to participate in individual semi-structured in-depth interviews designed to: (i) explore the meaning of IPCP; (ii) explore the facilitators of and barriers to IPCP; and (iii) examine the opportunities and challenges in interprofessional gerontological education. All interviews were tape-recorded and transcribed verbatim with thematic analysis conducted by two independent researchers. RESULTS: Three major themes emerged from the interviews: the need for IPCP; role preparedness, scope and liability; and strategies for interprofessional education. Respondents shared a common belief that IPCP improves the quality of life of older adults in both hospital and community settings by improving person-centred coordinated care and decision making in care planning. However, respondents perceived major barriers to IPCP to be lack of knowledge about healthcare professionals' scope of practice, lack of training in interprofessional collaboration, professional culture and stereotypes, and liability issues. Suggested approaches to overcome these barriers included innovative teaching and learning approaches, engaging students early on in the curriculum of health professional degree programmes, and enhancing collaborative effective communication in health and social care settings. CONCLUSIONS: It is anticipated that these findings will be used to inform the development of a new interprofessional gerontological education curriculum that aims to enhance students' competence in IPCP.

Effects of Acupuncture on the Recovery Outcomes of Stroke Survivors with Shoulder Pain: A Systematic Review.

BACKGROUND: Poststroke shoulder pain limits stroke survivors' physical functioning, impairs their ability to perform daily activities, and compromises their quality of life. The use of acupuncture to manage shoulder pain after a stroke is believed to free the blockage of energy flow and produce analgesic effects, but the evidence is unclear. We therefore conducted a systematic review to summarize the current evidence on the effects of acupuncture on the recovery outcomes of stroke survivors with shoulder pain. METHODS: Fourteen English and Chinese databases were searched for data from January 2009 to August 2017. The review included adult participants with a clinical diagnosis of ischemic or hemorrhagic stroke who had developed shoulder pain and had undergone conventional acupuncture, electroacupuncture, fire needle acupuncture, or warm needle acupuncture. The participants in the comparison group received the usual stroke care only. RESULTS: Twenty-nine randomized controlled trials were included. Most studies were assessed as having a substantial risk of bias. Moreover, due to the high heterogeneity of the acupuncture therapies examined, pooling the results in a meta-analysis was not appropriate. A narrative summary of the results is thus presented. The review showed that conventional acupuncture can be associated with benefits in reducing pain and edema and improving upper extremity function and physical function. The effects of conventional acupuncture on improving shoulder range of motion (ROM) are in doubt because this outcome was only examined in two trials. Electroacupuncture might be effective in reducing shoulder pain and improving upper extremity function, and conclusions on the effects of electroacupuncture on edema, shoulder ROM, and physical function cannot be drawn due to the limited number of eligible trials. The evidence to support the use of fire needle or warm needle acupuncture in stroke survivors with shoulder pain is also inconclusive due to the limited number of studies. CONCLUSION: Although most studies reviewed concluded that conventional and electroacupuncture could be effective for management of shoulder pain after stroke, the very high potential for bias should be considered. Further work in this area is needed that employs standardized acupuncture treatment modalities, endpoint assessments, and blinding of treatments.

Community pharmacists' perceptions about pharmaceutical service of over-the-counter traditional Chinese medicine: a survey study in Harbin of China.

BACKGROUND: This study aims to investigate community pharmacist's perception on the provision of over-the-counter (OTC) traditional Chinese medicine (TCM) pharmaceutical services; focusing on the areas of their attitude, general practice, perceived barriers and suggested improvements. METHODS: Questionnaire survey targeting community pharmacists in Harbin of China was applied in this study. Questionnaires were distributed and collected at community pharmacies. Data was analyzed by combining descriptive analysis and Chi-test. RESULTS: 280 valid questionnaires were collected, giving a response rate of 78%. Respondents generally showed positive attitude towards OTC TCM pharmaceutical services. However, they were uncertain about whether such pharmaceutical services should be considered as their primary responsibility. Respondents indicated that they acted proactively to find out all the medicines taken by their patients and to remind consumers of possible OTC TCM adverse reactions. However, they were less keen on recommending or re-directing consumers to suitable OTC TCM. The three main barriers hindering the provision of OTC TCM pharmaceutical service identified in this study were "insufficient professional knowledge" (54.6%), "ambiguity of the professional role of pharmacists" (54.6%) and "lack of scientific evidence of OTC TCM" (45.4%). The three main actions considered most relevant to improving pharmaceutical service of OTC TCM were "formulating or refining legislation to clarify the legal and professional role of pharmacists with respect to TCM" (60.7%), "strengthening training of pharmacists with respect to TCM" (57.9%), and "promoting public awareness of the pharmacist's role" (53.6%). According to the results of Chi-test, respondents' perceptions about the attitude, practice, perceived barriers, and improvement suggestions were significantly different depending on the education levels, certificate types and workloads of western medicine. CONCLUSIONS: The community pharmacists in Harbin, China were positive about the provision of OTC TCM pharmaceutical services. However, they were less certain about taking this duty as their primary responsibility. Insufficient knowledge and lack of role definition in the area of OTC TCM were found to be the major factors discouraging the provision of pharmaceutical service on OTC TCM by community pharmacists.
