ABSTRACT

BACKGROUND: Systematic reviews (SRs) could offer the best evidence supporting interventions, but methodological flaws limit their trustworthiness in decision-making. This cross-sectional study appraised the methodological quality of SRs on atopic dermatitis (AD) treatments. METHODS: We searched MEDLINE, EMBASE, PsycINFO, and Cochrane Database for SRs on AD treatments published in 2019-2022. We extracted SRs' bibliographical data and appraised SRs' methodological quality with AMSTAR (A MeaSurement Tool to Assess systematic Reviews) 2. We explored associations between methodological quality and bibliographical characteristics. RESULTS: Among the 52 appraised SRs, only one (1.9%) had high methodological quality, while 45 (86.5%) critically low. For critical domains, only five (9.6%) employed comprehensive search strategy, seven (13.5%) provided list of excluded studies, 17 (32.7%) considered risk of bias in primary studies, 21 (40.4%) contained registered protocol, and 24 (46.2%) investigated publication bias. Cochrane reviews, SR updates, SRs with European corresponding authors, and SRs funded by European institutions had better overall quality. Impact factor and author number positively associated with overall quality. CONCLUSIONS: Methodological quality of SRs on AD treatments is unsatisfactory. Future reviewers should improve the above critical methodological aspects. Resources should be devolved into upscaling evidence synthesis infrastructure and improving critical appraisal skills of evidence users.

ABSTRACT

This short report evaluated the accuracy and quality of information provided by ChatGPT regarding the use of complementary and integrative medicine for cancer. Using the QUality Evaluation Scoring Tool, a panel of 12 reviewers assessed ChatGPT's responses to 8 questions. The study found that ChatGPT provided moderate-quality responses that were relatively unbiased and not misleading. However, the chatbot's inability to reference specific scientific studies was a significant limitation. Patients with cancer should not rely on ChatGPT for clinical advice until further systematic validation. Future studies should examine how patients perceive ChatGPT's information and its impact on communication with health care professionals.

ABSTRACT

OBJECTIVE: Systematic reviews (SRs) offer updated evidence to support decision-making on sepsis treatments. However, the rigour of SRs may vary, and methodological flaws may limit their validity in guiding clinical practice. This cross-sectional study appraised the methodological quality of SRs on sepsis treatments. METHODS: We searched MEDLINE, EMBASE, and Cochrane Database for eligible SRs on randomised controlled trials on sepsis treatments with at least one meta-analysis published between 2018 and 2023. We extracted SRs' bibliographical characteristics with a pre-designed form and appraised their methodological quality using AMSTAR (A MeaSurement Tool to Assess systematic Reviews) 2. We applied logistic regressions to explore associations between bibliographical characteristics and methodological quality ratings. RESULTS: Among the 102 SRs, two (2.0%) had high overall quality, while respectively four (3.9%), seven (6.9%) and 89 (87.3%) were of moderate, low, and critically low quality. Performance in several critical methodological domains was poor, with only 32 (31.4%) considering the risk of bias in primary studies in result interpretation, 22 (21.6%) explaining excluded primary studies, and 16 (15.7%) applying comprehensive searching strategies. SRs published in higher impact factor journals (adjusted odds ratio: 1.19; 95% confidence interval: 1.05 to 1.36) was associated with higher methodological quality. CONCLUSIONS: The methodological quality of recent SRs on sepsis treatments is unsatisfactory. Future reviewers should address the above critical methodological aspects. More resources should also be allocated to support continuous training in critical appraisal among healthcare professionals and other evidence users.

ABSTRACT

BACKGROUND & AIMS: The concurrent use of herbal and dietary supplements and conventional drugs can lead to interactions in patients with cancer, of which hepatotoxicity is one of the most concerning sequelae. This study examined the potential supplement-drug interactions involving the hepatic system, and their associations with documented liver diseases, among patients with cancer in a large population-based cohort in the UK Biobank. METHODS: Participants diagnosed with cancer and had completed supplement-use assessment after diagnosis were included. Potentially interacting supplement-drug combinations that involved CYP enzymes or increased the risk of hepatotoxicity were identified from four tertiary databases. Liver diseases were identified using ICD-codes K70-77. Log-binomial regression was used to investigate the associations between potentially-interacting supplement-drug combinations and liver diseases documented (1) at any time, and (2) confined to only after the time of supplement-use assessment, adjusting for age, sex and pre-existing comorbidities. RESULTS: This analysis included 30,239 participants (mean age = 60.0 years; 61.9% female). Over half (n = 17,698, 58.5%) reported the use of supplements after cancer diagnoses. Among supplements users, 36.9% (n = 6537/17,698) were on supplement-drug combinations with interacting potential involving the hepatic system. Patients taking supplements and drugs who had hepatic comorbidities were more likely to take potentially interacting pairs (adjusted risk ratio = 1.14, 95% CI = 1.06-1.23, p < 0.001). However, no significant association was observed between the use of these combinations and subsequent liver diseases (all p > 0.05). CONCLUSION: Approximately one-third of the participants who had cancer and were supplement users had a risk of potential supplement-drug interactions that contribute to adverse liver effect. Healthcare professionals should communicate with patients with cancer, especially those with pre-existing liver diseases, about supplement use and proactively assess the clinical significance of potential interactions.

ABSTRACT

BACKGROUND: A proliferation of theories, models, and frameworks (TMFs) have been developed in the implementation science field to facilitate the implementation process. The basic features of these TMFs have been identified by several reviews. However, systematic appraisals on the quality of these TMFs are inadequate. To fill this gap, this study aimed to assess the usability, applicability, and testability of the current TMFs in a structured way. METHODS: A scoping review method was employed. Electronic databases were searched to locate English and Chinese articles published between January 2000 and April 2022. Search terms were specific to implementation science. Additionally, hand searches were administered to identify articles from related reviews. Purpose and characteristics such as the type of TMF, analytical level, and observation unit were extracted. Structured appraisal criteria were adapted from Birken et al.'s Theory Comparison and Selection Tool (T-CaST) to conduct an in-depth analysis of the TMFs' usability, applicability, and testability. RESULTS: A total of 143 TMFs were included in this analysis. Among them, the most common purpose was to identify barriers and facilitators. Most TMFs applied the descriptive method to summarize the included constructs or the prescriptive method to propose courses of implementation actions. TMFs were mainly mid-range theories built on existing conceptual frameworks or demonstrated grand theories. The usability of the TMFs needs to be improved in terms of the provision of conceptually matched strategies to barriers and facilitators and instructions on the TMFs usage. Regarding the applicability, little attention was paid to the constructs of macro-level context, stages of scale-up and sustainability, and implementation outcomes like feasibility, cost, and penetration. Also, fewer TMFs could propose recommended research and measurement methods to apply the TMFs. Lastly, explicit hypotheses or propositions were lacking in most of the TMFs, and empirical evidence was lacking to support the claimed mechanisms between framework elements in testability. CONCLUSIONS: Common limitations were found in the usability, application, and testability of the current TMFs. The findings of this review could provide insights for developers of TMFs for future theoretical advancements.

ABSTRACT

Background: Primary care patients, especially those with an older age, are one of the most vulnerable populations for post-COVID-19 symptoms. Identifying predictors of post-COVID symptoms can help identify high-risk individuals for preventive care. Methods: Out of 977 primary care patients aged 55 years or above with comorbid physical and psychosocial conditions in a prospective cohort in Hong Kong, 207 patients infected in the previous 5-24 weeks were included. The three most common post-COVID-19 symptoms (breathlessness, fatigue, cognitive difficulty), which lasted beyond the 4-week acute infection period, were assessed using items from the COVID-19 Yorkshire Rehabilitation Scale (C19-YRS), together with other self-reported symptoms. Multivariable analyses were conducted to identify predictors of post-acute and long COVID-19 symptoms (5-24 weeks after infection). Results: The 207 participants had a mean age of 70.8 ± 5.7 years, 76.3% were female, and 78.7% had ≥2 chronic conditions. In total, 81.2% reported at least one post-COVID symptom (mean: 1.9 ± 1.3); 60.9, 56.5 and 30.0% reported fatigue, cognitive difficulty, and breathlessness respectively; 46.1% reported at least one other new symptom (such as other respiratory-related symptoms (14.0%), insomnia or poor sleep quality (14.0%), and ear/nose/throat symptoms (e.g., sore throat) (10.1%), etc.). Depression predicted post-COVID-19 fatigue. The female sex predicted cognitive difficulty. Receiving fewer vaccine doses (2 doses vs. 3 doses) was associated with breathlessness. Anxiety predicted a higher overall symptom severity level of the three common symptoms. Conclusion: Depression, the female sex, and fewer vaccine doses predicted post-COVID symptoms. Promoting vaccination and providing intervention to those at high-risk for post-COVID symptoms are warranted.

ABSTRACT

BACKGROUND: Patients with cancer are increasingly using forums and social media platforms to access health information and share their experiences, particularly in the use of traditional, complementary, and integrative medicine (TCIM). Despite the popularity of TCIM among patients with cancer, few related studies have used data from these web-based sources to explore the use of TCIM among patients with cancer. OBJECTIVE: This study leveraged multiple forums and social media platforms to explore patients' use, interest, and perception of TCIM for cancer care. METHODS: Posts (in English) related to TCIM were collected from Facebook, Twitter, Reddit, and 16 health forums from inception until February 2022. Both manual assessments and natural language processing were performed. Descriptive analyses were performed to explore the most commonly discussed TCIM modalities for each symptom and cancer type. Sentiment analyses were performed to measure the polarity of each post or comment, and themes were identified from posts with positive and negative sentiments. TCIM modalities that are emerging or recommended in the guidelines were identified a priori. Exploratory topic-modeling analyses with latent Dirichlet allocation were conducted to investigate the patients' perceptions of these modalities. RESULTS: Among the 1,620,755 posts available, cancer-related symptoms, such as pain (10/10, 100% cancer types), anxiety and depression (9/10, 90%), and poor sleep (9/10, 90%), were commonly discussed. Cannabis was among the most frequently discussed TCIM modalities for pain in 7 (70%) out of 10 cancer types, as well as nausea and vomiting, loss of appetite, anxiety and depression, and poor sleep. A total of 7 positive and 7 negative themes were also identified. The positive themes included TCIM, making symptoms manageable, and reducing the need for medication and their side effects. The belief that TCIM and conventional treatments were not mutually exclusive and intolerance to conventional treatment may facilitate TCIM use. Conversely, TCIM was viewed as leading to patients' refusal of conventional treatment or delays in diagnosis and treatment. Doctors' ignorance regarding TCIM and the lack of information provided about TCIM may be barriers to its use. Exploratory analyses showed that TCIM recommendations were well discussed among patients; however, these modalities were also used for many other indications. Other notable topics included concerns about the legalization of cannabis, acupressure techniques, and positive experiences of meditation. CONCLUSIONS: Using machine learning techniques, social media and health forums provide a valuable resource for patient-generated data regarding the pattern of use and patients' perceptions of TCIM. Such information will help clarify patients' needs and concerns and provide directions for research on integrating TCIM into cancer care. Our results also suggest that effective communication about TCIM should be achieved and that doctors should be more open-minded to actively discuss TCIM use with their patients.

ABSTRACT

INTRODUCTION: The emergence and persistence of symptoms after acute COVID-19 is expected to become a major burden on healthcare systems. We assessed the features of the post-COVID-19 Syndrome (Long COVID) burden in a cohort of COVID-19 patients during the fifth major wave in Hong Kong. METHODS: A cross-sectional study of 135 patients with confirmed COVID-19 from Feb to Apr 2022 who utilized traditional Chinese medicine telemedicine services was conducted. The COVID-19 Yorkshire Rehabilitation Scale was administered using an online survey 12 weeks after the COVID-19 infection. Prevalence of symptom severity and functional impairments were assessed to identify burdens and patterns. The correlation between symptom severity, functional impairments, patient characteristics, and overall health was evaluated. RESULTS: The mean age was 46.8 years, with 46 (34.1%) males. Symptoms, functional impairments, and overall health worsened significantly when compared to the status prior to the infection. More than 50% reported the following sequelae 12 weeks after the acute infection: breathlessness, laryngeal or airway complications, fatigue, weakness, sleep, cognition, and anxiety. The presence of a single symptom or functional impairment significantly correlated with at least seven other problems positively, except for pain. Severity tended to be higher among vulnerable groups, including those who were chronic disease patients, older, less well educated, female, or had incomplete COVID-19 vaccinations. CONCLUSIONS: Long COVID is a significant healthcare burden among telemedicine users in Hong Kong, with complex needs for symptom and functional impairment management. Designing relevant health and rehabilitation services tailored to the needs of these patients is warranted.

ABSTRACT

PURPOSE: Despite the increasing popularity of supplement use among the cancer community, the current evidence on its effect on mortality in large studies is inconclusive. This study examined the association of dietary supplement use with mortality risk in a large population-based cohort. METHODS: This prospective cohort study analyzed data from the UK Biobank on participants who were diagnosed with cancer before July 31, 2019 and self-reported whether they had regular intake of dietary supplements (vitamins, minerals, or non-vitamin non-mineral [NVNM] supplements) after cancer diagnosis. The associations between the use of supplements with mortality were analyzed using Cox proportional hazards models, adjusting for confounders (sociodemographic factors, lifestyle and comorbidities). RESULTS: This analysis included 30,239 participants (mean age: 60.0 years; 61.9% female). Over half (57.8%) were supplement users. At a median follow-up of 11.9 years, 5577 all-cause deaths were registered. A marginal protective effect of supplement use on the risk of all-cause (adjusted hazard ratio [aHR] = 0.95, 95% CI = 0.90-0.99) and cancer (aHR = 0.89, 95% CI = 0.83-0.95) mortality were found, but not the risk of mortality due to other causes. In subgroup analyses, only NVNM dietary supplements were significantly associated with a lower risk of all-cause mortality (aHR = 0.88, 95% CI = 0.83-0.93). Both vitamins (aHR = 0.93, 95% CI = 0.87-0.99) and NVNM dietary supplements (aHR = 0.88, 95% CI = 0.82-0.94) were associated with a modest decrease in cancer mortality which were marginally significant. CONCLUSIONS: This is one of the largest cohort studies that identified the associations of dietary supplements with survival in the cancer population. However, the associations are small and should be interpreted cautiously due to the variations among different supplements and the small effect size. Future studies should investigate the effect of individual supplements, particularly NVNM supplements, on improving other cancer-related outcomes.

ABSTRACT

This study aimed to test the influence of vaccination characteristics and gain/loss-framing of information, on parental acceptance of the coronavirus disease 2019 (COVID-19) vaccination for their minor children. A discrete choice experiment was conducted among parents of children aged 0-17 years from September to October 2021 in Hong Kong. Respondents were randomly assigned to four groups with different framing of information and asked to choose hypothetical vaccination alternatives, described by seven attributes that were derived from prior qualitative interviews. A mixed logit model was adopted to analyze the effect of attributes and information framing on parental vaccination acceptance. The vaccine acceptance rates under different scenarios were also estimated. A total of 298 valid responses were obtained. It was found that the BioNTech brand, higher efficacy, less serious adverse events and more vaccination coverage in children significantly improved parental acceptance. Additionally, loss-framing increased parental acceptance compared with gain-framing, while the presentation of mortality information did not make a difference. Acceptance was also associated with parental uptake of the COVID-19 vaccine and the children's age. CONCLUSION: The findings imply that factors including gain/loss information framing, importance of vaccine characteristics, and peer influence have a significant effect on parents' decisions to get their children vaccinated. Parents with younger children had greater vaccine hesitancy, and information framing techniques should be considered in vaccination promotion for combating such vaccine hesitancy. Future studies could be conducted to identify the moderators and mediators of information framing to facilitate its implementation. WHAT IS KNOWN: • Parental acceptance of COVID-19 vaccine was found to be associated with various socio-economic and psychosocial factors, while the evidence on impact of vaccination characteristics was limited. • Behavioral interventions, including information framing, have been used to promote various health behaviors. WHAT IS NEW: • Loss-framing of information on vaccine effectiveness improves vaccine acceptance, while additional information on how the vaccine reduces death does not make a difference, which can be used to inform communication with the public in vaccination promotion. • The social norm (i.e., the vaccine uptake amongst other people) is important for increasing the parental vaccine acceptance rate.

ABSTRACT

This review aimed to systematically review and meta-analyze the effects of interventions in improving bracing compliance among adolescent idiopathic scoliosis (AIS) patients. Eight databases were searched from their inception to April 2022. The eligibility criteria included controlled studies that used any type of intervention to enhance bracing compliance in braced AIS patients. Two researchers independently screened articles and extracted data based on the PICO (participant, intervention, comparator, and outcome) framework. Quality appraisal of included studies was performed using GRADE (overall assessment), and the risk of bias was assessed with Cochrane RoB Tool 2 for randomized controlled trials (RCT) and ROBINS-I for non-RCT studies. The primary outcome was bracing compliance and secondary outcomes included Cobb Angle and measurements for quality of life. Six eligible studies involving 523 participants were included. All studies were evaluated as low or very low quality with a high risk of bias. Four types of interventions were identified, including sensor monitoring (n = 2, RCTs), auto-adjusted brace (n = 1, RCT), more intensive or collaborated medical care (n = 2), and psychosocial intervention (n = 1). A meta-analysis of 215 patients from the three RCTs suggested that the compliance-enhancing intervention group had 2.92 more bracing hours per day than the usual care control (95%CI [1.12, 4.72], P = 0.001). In subgroup analysis, sensor monitoring significantly improved bracing wearing quantity compared to usual care (3.47 hours/day, 95%CI [1.48, 5.47], P = 0.001), while other aforementioned interventions did not show a significant superiority. Compliance-enhancing interventions may be favorable in preventing curve progression and promoting quality of life, but the improvements cannot be clarified according to limited evidence. In conclusion, although the results of this study suggested that sensor monitoring may be the most promising approach, limited high-quality evidence precludes reliable conclusions. Future well-designed RCTs are required to confirm the actual benefit of compliance-improving interventions in clinical practice.

ABSTRACT

BACKGROUND: The concurrent use of conventional drugs and herbal medicines is becoming popular among patients with cancer. However, the potential risk of herb-drug interactions (HDI) remains under-addressed in the literature. Previous reviews have mainly focused on the prevalence of interactions, with less attention paid to the methods used by pharmacoepidemiological studies on evaluating HDI. This scoping review aims to summarize the existing pharmacoepidemiological studies that evaluate HDI using real-world data and to identify gaps to be addressed in future research. METHODS: A comprehensive search was performed in nine English- and Chinese-language databases from their inception to May 2021. Gray literature and manual searches were conducted to identify additional studies. The recommended components of the pharmacoepidemiological studies and key findings related to HDI were summarized. The proportion (%) of patients with cancer at risk of HDI was estimated by combining data from eligible studies. RESULTS: Twenty-eight studies were included in the review. More than half of these studies were cross-sectional studies (n = 18, 64.3%), followed by retrospective cohort studies (n = 5, 17.9%) and prospective cohort studies (n = 2, 7.1%). The three cancer drugs most commonly studied for their interaction potential with herbs were tamoxifen (n = 11, 39.3%), cyclophosphamide (n = 6, 21.4%), and paclitaxel (n = 6, 21.4%). Most cross-sectional studies identified potential HDI using tertiary databases and primary literature searches. Conversely, prospective and retrospective studies mainly investigated actual clinical outcomes, such as adverse events and secondary cancer occurrences. Most interaction outcomes identified using real-world data did not lead to negative clinical consequences. Collectively, 45.4% of herbal medicine users of the included studies were found to be at risk of HDI. We infer from this review that the common limitations of these studies were limited sample size, lack of data on herbal medicine use and details of HDI, and lack of evidence of HDI. Based on the study limitations, several recommendations to enrich the data sources and optimize the study designs were proposed. CONCLUSIONS: There is a high demand for pharmacoepidemiological research on HDI, considering the increasing popularity of herbal medicine among patients with cancer. It is anticipated that emerging real-world data in this field can guide the development of safe and effective approaches to integrative oncology.

ABSTRACT

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.

ABSTRACT

OBJECTIVE: Social distancing is one of the main non-pharmaceutical interventions used in the control of the COVID-19 pandemic. This scoping review aims to synthesise research findings on the effectiveness of different types and levels of social distancing measures in the earlier stage of COVID-19 pandemic without the confounding effect of mass vaccination. DESIGN: Scoping review. DATA SOURCES: MEDLINE, Embase, Global Health and four other databases were searched for eligible studies on social distancing for COVID-19 published from inception of the databases to 30 September 2020. STUDY SELECTION AND DATA EXTRACTION: Effectiveness studies on social distancing between individuals, school closures, workplace/business closures, public transport restrictions and partial/full lockdown were included. Non-English articles, studies in healthcare settings or not based on empirical data were excluded. RESULTS: After screening 1638 abstracts and 8 additional articles from other sources, 41 studies were included for synthesis of findings. The review found that the outcomes of social distancing measures were mainly indicated by changes in Rt , incidence and mortality, along with indirect indicators such as daily contact frequency and travel distance. There was adequate empirical evidence for the effect of social distancing at the individual level, and for partial or full lockdown at the community level. However, at the level of social settings, the evidence was moderate for school closure, and was limited for workplace/business closures as single targeted interventions. There was no evidence for a separate effect of public transport restriction. CONCLUSIONS: In the community setting, there was stronger evidence for the combined effect of different social distancing interventions than for a single intervention. As fatigue of preventive behaviours is an issue in public health agenda, future studies should analyse the risks in specific settings such as eateries and entertainment to implement and evaluate measures which are proportionate to the risk.

ABSTRACT

OBJECTIVE: To systematically review the effectiveness of hypertonic dextrose prolotherapy (DPT) on pain intensity and physical functioning in patients with lateral elbow tendinosis (LET) compared with other active non-surgical treatments. DATA SOURCES: Systematic search of Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, Web of Science, PubMed, Dimensions, Global Health, NHS Health Technology Assessment, Allied and Complementary Medicine, and OVID nursing database from inception to June 15, 2021, without language restrictions. STUDY SELECTION: Two reviewers independently identified parallel or crossover randomized controlled trials that evaluated the effectiveness of DPT in LET. The search identified 245 records; data from 8 studies (354 patients) were included. DATA EXTRACTION: Two reviewers independently extracted data and assessed included studies. The Cochrane Risk of Bias 2 tool was used to evaluate risk of bias. The Grading of Recommendation Assessment, Development, and Evaluation approach was used to assess quality of the evidence. DATA SYNTHESIS: Pooled results favored the use of DPT in reducing tennis elbow pain intensity compared with active controls at 12 weeks postenrollment, with a standardized mean difference of -0.44 (95% confidence interval, -0.88 to -0.01, P=.04) and of moderate heterogeneity (I2=49%). Pooled results also favored the use of DPT on physical functioning compared with active controls at 12 weeks, with Disabilities of the Arm, Shoulder and Hand scores achieving a mean difference of -15.04 (95% confidence interval, -20.25 to -9.82, P<.001) and of low heterogeneity (I2=0.0%). No major related adverse events have been reported. CONCLUSIONS: DPT is superior to active controls at 12 weeks for decreasing pain intensity and functioning by margins that meet criteria for clinical relevance in the treatment of LET. Although existing studies are too small to assess rare adverse events, for patients with LET, especially those refractory to first-line treatments, DPT can be considered a nonsurgical treatment option in carefully selected patients. Further high-quality trials with comparison with other injection therapies are needed.

ABSTRACT

OBJECTIVES: Depressive symptoms are common among mild cognitive impairment (MCI) patients. It is unknown how different the effects on depressive symptoms are among various pharmacological MCI interventions. This systematic review aimed to evaluate the comparative effectiveness of non-pharmacological MCI interventions on depressive symptoms among MCI patients. METHODS: A systematic review and network meta-analysis was conducted on randomized controlled trials (RCT) comparing the effect of different non-pharmacological MCI interventions on changes in depressive symptoms among MCI patients. RCTs were identified from MEDLINE, EMBASE, Cochrane Library, CINAHL, PsycINFO, and PsycARTICLES. Results were summarized as standardized mean differences (SMD) and 95% confidence intervals (CI). The surface under the cumulative ranking (SUCRA) was used to rank the effect of different interventions. RESULTS: Twenty-two RCTs were included in the network meta-analysis. Compared with non-active control, cognition-based intervention (SMD=-0.25, 95% CI: -0.46, -0.04) and physical exercise (SMD=-0.33, 95% CI: -0.56, -0.10) had significant positive effects to reduce depressive symptoms. Health education, psychosocial intervention, and the combination of physical exercise and cognition-based intervention had non-significant overall effects. The SUCRA demonstrated that physical exercise had the highest SUCRA for the reduction in depression symptoms (0.815). In subgroup analysis, health education, cognition-based intervention, physical exercise, and the combination of physical exercise and cognition-based intervention showed significant longer-term effects (6-12 months). CONCLUSION: Physical exercise and cognition-based intervention were effective interventions for depressive symptoms in MCI patients. This study can provide additional evidence for healthcare providers to make decisions for selecting available and appropriate interventions for MCI patients.

ABSTRACT

Background: Along with individual-level factors, vaccination-related characteristics are important in understanding COVID-19 vaccine hesitancy. This study aimed to determine the influence of these characteristics on vaccine acceptance to formulate promotion strategies after considering differences among respondents with different characteristics. Methods: An online discrete choice experiment was conducted among people aged 18-64 years in Hong Kong, China, from 26 to 28 February 2021. Respondents were asked to make choices regarding hypothetical vaccination programmes described by vaccination-related characteristics-the attributes derived from a prior individual interview. Subgroup analysis was performed to identify the differences in vaccination-related characteristics among respondents with different personal characteristics. Results: A total of 1,773 respondents provided valid responses. The vaccine efficacy and brand were the most important factors affecting acceptance, followed by the exemption of quarantine for vaccinated travelers, safety, venue for vaccination, vaccine uptake of people in their lives, and recommendations by general physicians or government. Frequent exposure to vaccination information on social media has been associated with increasing vaccine refusal. Substantial preference heterogeneity for the attributes was found among people of different ages, incomes, chronic conditions, and previous acceptance of influenza vaccines. Conclusion: The findings provided evidence to formulate interventions to promote vaccine uptake, including the provision of vaccination at housing estate or workplaces, involvement of general physicians and interpersonal communication in vaccine promotion and information dissemination, and exemption of quarantine for vaccinated people. Moreover, social media is a significant information channel that cannot be neglected in the dissemination of official information.

ABSTRACT

Background: There is a lack of study comprehensively comparing the effects of all existing types of interventions on global cognition among patients with mild cognitive impairment (MCI). Aims: To conduct a network meta-analysis to evaluate the effectiveness of different types of interventions in improving global cognition among MCI patients. Methods: Randomized controlled trials (RCTs) assessing the effects of pharmacological or non-pharmacological interventions on the Mini-Mental State Examination (MMSE) in MCI patients were included. Two authors independently screened the studies and extracted the data. Random-effects network meta-analysis was used to synthesize the data. Results were summarized as mean difference (MD) and corresponding 95% CIs of MMSE in forest plots. Results: Fifty RCTs with 5,944 MCI patients met the inclusion criteria and 49 were included in the network meta-analysis. Compared with the control group, cognition-based intervention (MD = 0.80, 95% CI 0.04-1.57), physical exercise (MD = 1.92, 95% CI 1.19-2.64), combined physical exercise and cognition-based intervention (MD = 1.86, 95% CI 0.60-3.12), and antioxidants (MD = 0.94, 95% CI 0.04-1.83) had positive effects on MMSE in participants with MCI. There was no significant difference between all other interventions included and the control group. Conclusions: This study suggested that cognition-based intervention, physical exercise, combined physical exercise and cognition-based intervention, and antioxidants could be among the most effective interventions on global cognition in older adults with MCI. The availability, acceptability, and cost-effectiveness of interventions should also be taken into consideration when selecting interventions. Registration: PROSPERO CRD42020171985.

ABSTRACT

BACKGROUND: In response to the World Health Organization's recommendation, policy makers have been adopting evidence-based healthcare approach to promote the development of traditional, complementary and integrative medicine (TCIM) into Hong Kong's health system. Disseminating synopses of clinical evidence from systematic reviews or randomized trials is regarded as a potentially effective strategy to promote evidence uptake. The study aimed to identify barriers and facilitators to implementing this strategy among Hong Kong Chinese medicine practitioners (CMPs). METHODS: Twenty-five CMPs aged under 45 years and trained in Hong Kong after reunification with China in 1997 were interviewed individually. Four clinical evidence synopses of randomized trials and systematic reviews on Chinese medicine interventions were presented, and CMPs were asked to comment on their applicability in routine practice. The Consolidated Framework for Implementation Research (CFIR) was applied to guide interview and analysis. RESULTS: The barriers included: i) CMPs' perceived difficulties in applying complex evidence in decision-making and ii) inadequate training and limited consultation time. The facilitators were i) availability of publicly accessible and user-friendly synopses, ii) formation of community of evidence-based practice among CMPs with input from key opinion leaders, iii) opportunity for interprofessional collaborations with conventional healthcare providers, and iv) patients' demand for evidence-based clinical advice. Besides, i) CMPs' knowledge and beliefs in evidence-based healthcare approach, ii) presentations of evidence-based information in the synopses, and iii) clinical decision making as influenced by quality of evidence reported acted as both barriers and facilitators. CONCLUSIONS: This CFIR-based qualitative study investigated how the World Health Organization recommendation of promoting evidence use in routine practice was perceived by CMPs trained in Hong Kong after reunification with China in 1997. Key barriers and facilitators to applying evidence were identified. Such results will inform tailoring of implementation strategies for promoting evidence uptake, in the context of a well-developed health system dominated by conventional medicine.

ABSTRACT

Hypertonic dextrose prolotherapy (DPT) has been reported to be effective for temporomandibular disorders (TMDs) in clinical trials but its overall efficacy is uncertain. To conduct a systematic review with meta-analysis of randomized controlled trials (RCTs) to synthesize evidence on the effectiveness of DPT for TMDs. Eleven electronic databases were searched from their inception to October, 2020. The primary outcome of interest was pain intensity. Secondary outcomes included maximum inter-incisal mouth opening (MIO) and disability score. Studies were graded by "Cochrane risk of bias 2" tool; if data could be pooled, a meta-analysis was performed. Ten RCTs (n = 336) with some to high risk of bias were included. In a meta-analysis of 5 RCTs, DPT was significantly superior to placebo injections in reducing TMJ pain at 12 weeks, with moderate effect size and low heterogeneity (Standardized Mean Difference: - 0.76; 95% CI - 1.19 to - 0.32, I2 = 0%). No statistically significant differences were detected for changes in MIO and functional scores. In this systematic review and meta-analysis, evidence from low to moderate quality studies show that DPT conferred a large positive effect which met criteria for clinical relevance in the treatment of TMJ pain, compared with placebo injections.Protocol registration at PROSPERO: CRD42020214305.
