Association of healthy lifestyle behaviours with incident irritable bowel syndrome: a large population-based prospective cohort study

OBJECTIVES

To evaluate the association between healthy lifestyle behaviours and the incidence of irritable bowel syndrome (IBS).

DESIGN

Population-based prospective cohort study.

SETTING

The UK Biobank.

PARTICIPANTS

64 268 adults aged 37 to 73 years who had no IBS diagnosis at baseline were enrolled between 2006 and 2010 and followed up to 2022.

MAIN EXPOSURE

The five healthy lifestyle behaviours studied were never smoking, optimal sleep, high level of vigorous physical activity, high dietary quality and moderate alcohol intake.

MAIN OUTCOME MEASURE

The incidence of IBS.

RESULTS

During a mean follow-up of 12.6 years, 961 (1.5%) incident IBS cases were recorded. Among the 64 268 participants (mean age 55.9 years, 35 342 (55.0%) female, 7604 (11.8%) reported none of the five healthy lifestyle behaviours, 20 662 (32.1%) reported 1 behaviour, 21 901 (34.1%) reported 2 behaviours and 14 101 (21.9%) reported 3 to 5 behaviours at baseline. The multivariable adjusted hazard ratios associated with having 1, 2 and 3 to 5 behaviours for IBS incidence were 0.79 (95% confidence intervals 0.65 to 0.96), 0.64 (0.53 to 0.78) and 0.58 (0.46 to 0.72), respectively (P for trend <0.001). Never smoking (0.86, 0.76 to 0.98, P=0.02), high level of vigorous physical activity (0.83, 0.73 to 0.95, P=0.006) and optimal sleep (0.73, 0.60 to 0.88, P=0.001) demonstrated significant independent inverse associations with IBS incidence. No significant interactions were observed between these associations and age, sex, employment status, geographic location, gastrointestinal infection, endometriosis, family history of IBS or lifestyle behaviours.

CONCLUSIONS

Adhering to a higher number of healthy lifestyle behaviours is significantly associated with a lower incidence of IBS in the general population. Our findings suggest the potential of lifestyle modifications as a primary prevention strategy for IBS.

Association between regular proton pump inhibitors use and cardiovascular outcomes: A large prospective cohort study

BACKGROUND

Proton pump inhibitors (PPIs) are widely prescribed for gastroesophageal reflux disease and peptic ulcer disease. However, the association between the regular PPIs use and the risk of cardiovascular disease (CVD) outcomes remains unclear. We aimed to determine whether regular proton pump inhibitors (PPIs) use is associated with an altered incidence of cardiovascular disease (CVD) in the general population.

METHODS

This prospective cohort study included 459,207 participants (mean [SD] age, 56.2 [8.1] years) from the UK Biobank study without prevalent CVD who enrolled between 2006 and 2010 and were followed until 2018. Hazard ratios (HRs) and 95% confidence intervals (CIs) for incident CVD and its components (coronary heart disease [CHD], stroke, heart failure, atrial fibrillation, and venous thromboembolism) were obtained using Cox proportional hazards models with adjustment for potential confounding factors, including demographic factors, lifestyle behaviors, prevalent comorbidities, and clinical indicators for PPIs use.

RESULTS

During the follow-up period, we recorded 26,346 incident CVD events (including 13,749 CHD events, 4144 stroke events, 5812 atrial fibrillation events, 1159 heart failure events, and 4206 venous thromboembolism events). The fully adjusted HRs (and 95% CIs) associated with PPIs users compared to nonusers were 1.44 (95% CI 1.39-1.50) for incident CVD, 1.65 (95% CI 1.57-1.74) for CHD, 1.21 (95% CI 1.09-1.33) for stroke, 1.17 (95% CI 1.08-1.28) for atrial fibrillation, 1.61 (95% CI 1.37-1.89) for heart failure, and 1.36 (95% CI 1.24-1.50) for venous thromboembolism.

CONCLUSIONS

Regular PPIs use was associated with higher risk of CVD outcomes. Clinicians should therefore exercise caution when prescribing PPIs.

Effectiveness of Hypertonic Dextrose Injection (Prolotherapy) in Plantar Fasciopathy: A Systematic Review and Meta-analysis of Randomized Controlled Trials

OBJECTIVE

To systematically review the effectiveness of hypertonic dextrose prolotherapy (DPT) in plantar fasciopathy (PF) compared with other non-surgical treatments.

DATA SOURCES

PubMed/MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, Web of Science, Allied and Complementary Medicine Database, Global Health, Ovid Nursing Database, Dimensions, and WHO ICTRP were searched from inception to April 30th, 2022.

STUDY SELECTION

Two independent reviewers selected randomized controlled trials (RCTs) that evaluated the effectiveness of DPT in PF compared with non-surgical treatments. Outcomes included pain intensity, foot and ankle function, and plantar fascia thickness.

DATA EXTRACTION

Two independent reviewers conducted data extraction. Risk of bias (RoB) assessment was conducted using the Cochrane Risk of Bias 2 (RoB 2) tool, and certainty of evidence was assessed with Grading of Recommendation Assessment, Development, and Evaluation (GRADE).

DATA SYNTHESIS

Eight RCTs (n=469) met the inclusion criteria. Pooled results favored the use of DPT versus normal saline (NS) injections in reducing pain (weighted mean difference [WMD] -41.72; 95% confidence interval [CI] -62.36 to -21.08; P<.01; low certainty evidence) and improving function [WMD -39.04; 95% CI -55.24 to -22.85; P<.01; low certainty evidence] in the medium term. Pooled results also showed corticosteroid (CS) injections was superior to DPT in reducing pain in the short term [standardized mean difference 0.77; 95% CI 0.40 to 1.14; P<.01; moderate certainty evidence]. Overall RoB varied from "some concerns" to "high". The overall certainty of evidence presented ranges from very low to moderate based on the assessment with the GRADE approach.

CONCLUSION

Low certainty evidence demonstrated that DPT was superior to NS injections in reducing pain and improving function in the medium term, but moderate certainty evidence showed that it was inferior to CS in reducing pain in the short term. Further high-quality RCTs with standard protocol, longer-term follow-up, and adequate sample size are needed to confirm its role in clinical practice.

Contextualizing evidence-based nurse-led interventions for reducing 30-day hospital readmissions using GRADE evidence to decision framework: A Delphi study

BACKGROUND

High 30-day readmission rates increase hospital costs and negatively impact patient outcomes in many healthcare systems, including Hong Kong. Evidence-based and local adaptable nurse-led interventions have not been established for reducing 30-day hospital readmissions among general medical patients in Hong Kong's public healthcare system.

AIMS

The aim of this study was to select and refine evidence-based nurse-led interventions for reducing 30-day hospital readmissions among general medical patients in Hong Kong's public healthcare system using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) Evidence to Decision (EtD) framework.

METHODS

Eighteen local healthcare stakeholders were recruited to carry out a two-step process. In step 1, stakeholders were invited to prioritize nurse-led interventions which were supported by existing evidence and suggest important combinations of different interventions. For all interventions prioritized in step 1, step 2 involved stakeholders performing a two-round Delphi questionnaire aiming to generate consensus-based interventions appropriate to the local context. GRADE EtD framework was applied to guide the decision-making process, taking into account certainty of evidence, benefits and harms, resource use, equity, acceptability, and feasibility.

RESULTS

Four out of eight nurse-led interventions reached a positive consensus with percentage agreement ranging from 70.6% to 82.4%. GRADE EtD criteria ratings showed that over 70% of stakeholders agreed these four interventions were probably acceptable and feasible, though the certainty of evidence was low or moderate. Half of stakeholders believed their desirable effects compared to undesirable effects were large. However, the resources required and how these nurse-led interventions might affect health inequities when implemented were uncertain. Preliminary implementation issues included high complexity of delivering multiple nurse-led intervention components, and challenges of coordinating different involved parties in delivering the interventions. Appropriate resource allocation and training should be provided to address these potential problems, as suggested by stakeholders.

LINKING EVIDENCE TO ACTION

Using the GRADE EtD framework, four nurse-led interventions were recommended by healthcare stakeholders as possible strategies for reducing 30-day hospital readmissions among general medical patients in Hong Kong. To address preliminary implementation issues, nurses' role as care coordinators should also be strengthened to ensure smooth delivery of nurse-led intervention components, and to facilitate multidisciplinary collaboration during service delivery.

Integrative oncology in cancer care - implementation factors: mixed-methods systematic review

BACKGROUND

Integrative oncology (IO) appears to be beneficial to patients with cancer, but its implementation remains a challenge. Guided by the Theoretical Domains Framework (TDF) and the Capability-Opportunity-Motivation-Behaviour (COM-B) model, this systematic review identified the barriers to and facilitators of IO implementation in conventional cancer care settings.

METHODS

We searched eight electronic databases from their inception until February 2022 for qualitative, quantitative or mixed-methods empirical studies reporting the implementation outcomes for IO services. Critical appraisal approach was tailored according to study types. The identified implementation barriers and facilitators were mapped onto TDF domains and the COM-B model, and subsequently onto the behavioural change wheel (BCW) for formulating behavioural change interventions.

RESULTS

We included 28 studies (11 qualitative, 6 quantitative, 9 mixed-methods and 2 Delphi studies) of satisfied methodological quality. The main implementation barriers were the lack of IO knowledge, the absence of funding and healthcare professionals' low level of IO receptiveness. The key implementation facilitators were the dissemination of evidence on IO clinical benefits, the equipping of professionals with IO service delivery skills and the provision of a supportive organisational climate.

CONCLUSION

Multifaceted implementation strategies are needed to address the determinants influencing IO service delivery. Based on our BCW-based analysis of the included studies, the key behavioural change techniques are: (1) educating healthcare professionals about the value and application of traditional and complementary medicine; (2) ensuring access to actionable clinical evidence on IO effectiveness and safety and (3) designing guidelines on communicating traditional and complementary medicine interventions with patients and caregivers for biomedically trained doctors and nurses.

Methodological quality of systematic reviews on treatments for Alzheimer's disease: a cross-sectional study

BACKGROUND

Carefully conducted systematic reviews (SRs) can provide reliable evidence on the effectiveness of treatment strategies for Alzheimer's disease (AD). Nevertheless, the reliability of SR results can be limited by methodological flaws. This cross-sectional study aimed to examine the methodological quality of SRs on AD treatments, along with potentially relevant factors.

METHODS

To identify eligible SRs on AD treatments, four databases including the Cochrane Database of Systematic Reviews, MEDLINE, EMBASE, and PsycINFO were searched. The Assessing the Methodological Quality of Systematic Reviews 2 instrument was used for quality appraisal of SRs. Multivariable regression analyses were used to examine factors related to methodological quality.

RESULTS

A total of 102 SRs were appraised. Four (3.90%) SRs were considered as high quality; 14 (13.7%), 48 (47.1%), and 36 (35.3%) were as moderate, low, and critically low quality, respectively. The following significant methodological limitations were identified: only 22.5% of SRs registered protocols a priori, 6.9% discussed the rationales of chosen study designs, 21.6% gave a list of excluded studies with reasons, and 23.5% documented funding sources of primary studies. Cochrane SRs (adjusted odds ratio (AOR): 31.9, 95% confidence interval (CI): 3.81-266.9) and SRs of pharmacological treatments (AOR: 3.96, 95%CI: 1.27-12.3) were related to the higher overall methodological quality of SRs.

CONCLUSION

Methodological quality of SRs on AD treatments is unsatisfactory, especially among non-Cochrane SRs and SRs of non-pharmacological interventions. Improvement in the following methodological domains requires particular attention due to poor performance: registering and publishing protocols a priori, justifying study design selection, providing a list of excluded studies, and reporting funding sources of primary studies.

Comparing diagnostic performance of Cantonese-Chinese version of Rome IV criteria and a short Reference Standard for functional dyspepsia in China

Introduction

Functional dyspepsia (FD) is diagnosed based on self-reported symptoms and negative upper gastrointestinal endoscopic findings. The Rome criteria were not adopted as a diagnostic instrument in clinical guidelines due to their complexity. Different guidelines used relatively simple symptom assessment schemes with contents that vary significantly. A previously evaluated short Reference Standard may serve as a more standardised tool for guidelines. We evaluated its diagnostic accuracy against the Rome IV criteria in a cross-sectional study in Hong Kong.

Methods

A total of 220 dyspeptic patients sampled consecutively from a tertiary hospital and the community completed the Rome IV diagnostic questionnaire, which was translated into Cantonese-Chinese, and the Reference Standard. Sensitivity, specificity, positive and negative likelihood ratios (LRs), and area under the receiver operating characteristics curve (AUC), with 95% confidence intervals (CIs), were calculated.

Results

Among the participants, 160 (72.7%) fulfilled the Reference Standard with negative upper gastrointestinal endoscopic results. The Reference Standard identified patients with Rome IV-defined FD with 91.1% (95% CI 82.6%–96.4%) sensitivity and 37.6% (95% CI 29.6%–46.1%) specificity. The positive and negative LRs were 1.46 (95% CI 1.26–1.69) and 0.24 (95% CI 0.11–0.49), respectively. The AUC value was 0.64 (95% CI 0.59–0.69).

Conclusions

The Reference Standard can rule out patients without Rome IV-defined FD. It may be used as an initial screening tool for FD in settings where the use of the Rome IV criteria is impractical. It may also provide a uniform definition and diagnostic rule for future updates of clinical guidelines.

Quantification of prevalence, clinical characteristics, co-existence, and geographic variations of traditional Chinese medicine diagnostic patterns via latent tree analysis-based differentiation rules among functional dyspepsia patients

Background

Traditional Chinese Medicine (TCM) treatment strategies are guided by pattern differentiation, as documented in the eleventh edition of the International Classification of Diseases (ICD). However, no standards for pattern differentiation are proposed to ensure inter-rater agreement. Without standardisation, research on associations between TCM diagnostic patterns, clinical features, and geographical characteristics is also not feasible. This diagnostic cross-sectional study aimed to (i) establish the pattern differentiation rules of functional dyspepsia (FD) using latent tree analysis (LTA); (ii) compare the prevalence of diagnostic patterns in Hong Kong and Hunan; (iii) discover the co-existence of diagnostic patterns; and (iv) reveal the associations between diagnostic patterns and FD common comorbidities.

Methods

A total of 250 and 150 participants with FD consecutively sampled in Hong Kong and Hunan, respectively, completed a questionnaire on TCM clinical features. LTA was performed to reveal TCM diagnostic patterns of FD and derive relevant pattern differentiation rules. Multivariate regression analyses were performed to quantify correlations between different diagnostic patterns and between diagnostic patterns and clinical and geographical variables.

Results

At least one TCM diagnostic pattern was differentiated in 70.7%, 73.6%, and 64.0% of the participants in the overall (n = 400), Hong Kong (n = 250), and Hunan (n = 150) samples, respectively, using the eight pattern differentiation rules derived. 52.7% to 59.6% of the participants were diagnosed with two or more diagnostic patterns. Cold-heat complex (59.8%) and spleen-stomach dampness-heat (77.1%) were the most prevalent diagnostic patterns in Hong Kong and Hunan, respectively. Spleen-stomach deficiency cold was highly likely to co-exist with spleen-stomach qi deficiency (adjusted odds ratio (AOR): 53.23; 95% confidence interval (CI): 21.77 to 130.16). Participants with severe anxiety tended to have liver qi invading the stomach (AOR: 1.20; 95% CI: 1.08 to 1.33).

Conclusions

Future updates of the ICD, textbooks, and guidelines should emphasise the importance of clinical and geographical variations in TCM diagnosis. Location-specific pattern differentiation rules should be derived from local data using LTA. In future, patients’ pattern differentiation results, local prevalence of TCM diagnostic patterns, and corresponding TCM treatment choices should be accessible to practitioners on online clinical decision support systems to streamline service delivery.

Methodological quality of systematic reviews on Chinese herbal medicine: a methodological survey

BACKGROUND

Systematic reviews (SRs) synthesise the best evidence of effectiveness and safety on Chinese herbal medicine (CHM). Decision-making should be supported by the high-quality evidence of prudently conducted SRs, but the trustworthiness of conclusions may be limited by poor methodological rigour.

METHODS

This survey aimed to examine the methodological quality of a representative sample of SRs on CHM published during January 2018 to March 2020. We conducted literature search in Cochrane Database of Systematic Reviews, MEDLINE via Ovid, and EMBASE via Ovid. Eligible SRs must be in Chinese or English with at least one meta-analysis on the treatment effect of any CHM documented in the 2015 Chinese Pharmacopoeia. Two reviewers extracted the bibliographical characteristics of SRs and appraised their methodological quality using AMSTAR 2 (Assessing the Methodological Quality of Systematic Reviews 2). The associations between bibliographical characteristics and methodological quality were investigated using Kruskal-Wallis tests and Spearman's rank correlation coefficients.

RESULTS

We sampled and appraised one hundred forty-eight SRs. Overall, one (0.7%) was of high methodological quality; zero (0%), four (2.7%), and one-hundred forty-three (96.6%) SRs were of moderate, low, and critically-low quality. Only thirteen SRs (8.8%) provided a pre-defined protocol; none (0%) provided justifications for including particular primary study designs; six (4.1%) conducted a comprehensive literature search; two (1.4%) provided a list of excluded studies; nine (6.1%) undertook meta-analysis with appropriate methods; and seven (4.7%) reported funding sources of included primary studies. Cochrane reviews had higher overall quality than non-Cochrane reviews (P < 0.001). SRs with European funding support were less likely to have critically-low quality when compared with their counterparts (P = 0.020). SRs conducted by more authors (r_s = 0.23; P = 0.006) and published in higher impact factor journals (r_s = 0.20; P = 0.044) were associated with higher methodological quality.

CONCLUSIONS

Our results indicated that the methodological quality of SRs on CHM is low. Future authors should enhance the methodological quality through registering a priori protocols, justifying selection of study designs, conducting comprehensive literature search, providing a list of excluded studies with rationales, using appropriate method for meta-analyses, and reporting funding sources among primary studies.

Effectiveness of Peri-Discharge Complex Interventions for Reducing 30-Day Readmissions among COPD Patients: Overview of Systematic Reviews and Network Meta-Analysis

BACKGROUND

An overview of systematic reviews(SRs) and network meta-analysis(NMA) were conducted to evaluate the comparative effectiveness of peri-discharge complex interventions for reducing 30-day readmissions among chronic obstructive pulmonary disease(COPD) patients.

METHODS

Five databases were searched for SRs of randomized controlled trials(RCTs). An additional search was conducted for updated RCTs from database inception until Jun 2020. Pooled effect of peri-discharge complex interventions was assessed using random-effect pairwise meta-analyses. Comparative effectiveness across different peri-discharge complex interventions was evaluated using NMA.

RESULTS

Nine SRs and 11 eligible RCTs(n = 1,422) assessing eight different peri-discharge complex interventions were included. For reducing 30-day all-cause readmissions, pairwise meta-analysis showed no significant difference between peri-discharge complex interventions and usual care, while NMA indicated no significant differences among different peri-discharge complex interventions as well as usual care. For reducing 30-day COPD-related readmissions, peri-discharge complex interventions were significantly more effective than usual care (pooled RR = 0.45, 95% CI:0.24-0.84).

CONCLUSIONS

Peri-discharge complex interventions may not differ from usual care in reducing 30-day all-cause readmissions among COPD patients but some are more effective for lowering 30-day COPD-related readmission. Thus, complex intervention comprising core components of patient education, self-management, patient-centred discharge instructions, and telephone follow up may be considered for implementation, but further evaluation is warranted.

Chinese herbal medicine for functional dyspepsia: a network meta-analysis of prokinetic-controlled randomised trials

BACKGROUND

Prokinetic is the first-line conventional treatment for functional dyspepsia (FD) in Asia despite potential adverse events. Chinese herbal medicine (CHM) may be an effective and safe substitution. This network meta-analysis (NMA) aimed to evaluate the comparative effectiveness of different CHM formulae for FD against prokinetics.

METHODS

Seven international and Chinese databases were searched from their inception to July 2020 for randomised controlled trials (RCTs) on CHM versus prokinetics. Data from each RCT were first pooled using random-effect pairwise meta-analyses and illustrated as risk difference (RD) or standardised mean difference (SMD) with 95% confidence interval (CI). Random-effect NMAs were then performed to evaluate the comparative effectiveness of CHM formulae and displayed as RD with 95% CI or SMD with 95% credible interval (CrI). The GRADE partially contextualised framework was applied for NMA result interpretation.

RESULTS

Twenty-six unique CHM formulae were identified from twenty-eight RCTs of mediocre quality. Pairwise meta-analyses indicated that CHM was superior to prokinetics in alleviating global symptoms at 4-week follow-up (pooled RD: 0.14; 95% CI: 0.10-0.19), even after trim and fill adjustment for publication bias. NMAs demonstrated that Modified Zhi Zhu Decoction may have a moderate beneficial effect on alleviating global symptoms at 4-week follow-up (RD: 0.28; 95% CI: - 0.03 to 0.75). Xiao Pi Kuan Wei Decoction may have a large beneficial effect on alleviating postprandial fullness (SMD: - 2.14; 95% CI: - 2.76 to 0.70), early satiety (SMD: - 3.90; 95% CI: - 0.68 to - 0.42), and epigastric pain (SMD: - 1.23; 95% CI: - 1.66 to - 0.29). No serious adverse events were reported.

CONCLUSION

Modified Zhi Zhu Decoction and Xiao Pi Kuan Wei Decoction may be considered as an alternative for patients unresponsive to prokinetics. Confirmatory head-to-head trials should be conducted to investigate their comparative effectiveness against prokinetics.

Healthy Sleep Associated With Lower Risk of Hypertension Regardless of Genetic Risk: A Population-Based Cohort Study

Background: Hypertension is a leading contributor to the global burden of disease and to mortality. The combined effects of sleep factors on the risk of hypertension are unclear. We aimed to evaluate the effect of combined sleep factors on the risk of hypertension and to explore whether this association is independent of genetic risk. Methods: This population-based prospective cohort study included 170,378 participants from the UK Biobank study. We conducted a healthy sleep score based on a combination of major five sleep factors and a genetic risk score based on 118 risk variants. Cox proportional hazard regression models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs). Results: A total of 170,378 participants were included. Compared to participants with a healthy sleep score of 0-1, those with healthy sleep scores of 2 (HR, 0.90; 95% CI, 0.83-0.98), 3 (HR, 0.81; 95% CI, 0.75-0.88), 4 (HR, 0.74; 95% CI, 0.68-0.81), or 5 (HR, 0.67; 95% CI, 0.59-0.77) had increasingly lower risks of hypertension (P for trend <0.001). Participants with high genetic risk and an unfavorable sleep pattern had a 1.80-fold greater risk of hypertension than participants with low genetic risk and a favorable sleep pattern. The association between sleep patterns and hypertension persisted in subgroup analysis, stratified by the genetic risk. Nearly 18.2% of hypertension events in this cohort could be attributed to unfavorable sleep pattern. Conclusions: Favorable sleep pattern was associated with a low risk of hypertension, regardless of genetic risk. These findings highlight the potential of sleep interventions to reduce risk of hypertension across entire populations.

Low methodological quality of systematic reviews on acupuncture: a cross-sectional study

BACKGROUND

While well-conducted systematic reviews (SRs) can provide the best evidence on the potential effectiveness of acupuncture, limitations on the methodological rigour of SRs may impact the trustworthiness of their conclusions. This cross-sectional study aimed to evaluate the methodological quality of a representative sample of SRs on acupuncture effectiveness.

METHODS

Cochrane Database of Systematic Reviews, MEDLINE, and EMBASE were searched for SRs focusing on the treatment effect of manual acupuncture or electro-acupuncture published during January 2018 and March 2020. Eligible SRs must contain at least one meta-analysis and be published in English language. Two independent reviewers extracted the bibliographical characteristics of the included SRs with a pre-designed questionnaire and appraised the methodological quality of the studies with the validated AMSTAR 2 (A MeaSurement Tool to Assess systematic Reviews 2). The associations between bibliographical characteristics and methodological quality ratings were explored using Kruskal-Wallis rank tests and Spearman's rank correlation coefficients.

RESULTS

A total of 106 SRs were appraised. Only one (0.9%) SR was of high overall methodological quality, zero (0%) was of moderate-quality, six (5.7%) and 99 (93.4%) were of low-quality and critically low-quality respectively. Among appraised SRs, only ten (9.4%) provided an a priori protocol, four (3.8%) conducted a comprehensive literature search, five (4.7%) provided a list of excluded studies, and six (5.7%) performed meta-analysis appropriately. Cochrane SRs, updated SRs, and SRs that did not search non-English databases had relatively higher overall quality.

CONCLUSIONS

Methodological quality of SRs on acupuncture is unsatisfactory. Future reviewers should improve critical methodological aspects of publishing protocols, performing comprehensive search, providing a list of excluded studies with justifications for exclusion, and conducting appropriate meta-analyses. These recommendations can be implemented via enhancing the technical competency of reviewers in SR methodology through established education approaches as well as quality gatekeeping by journal editors and reviewers. Finally, for evidence users, skills in SR critical appraisal remain to be essential as relevant evidence may not be available in pre-appraised formats.

Association of sleep and circadian patterns and genetic risk with incident type 2 diabetes: a large prospective population-based cohort study

OBJECTIVE

To examine the association of incident type 2 diabetes (T2D) risk with sleep factors, genetic risk, and their combination effects.

DESIGN

Large prospective population-based cohort study.

METHODS

This population-based prospective cohort study included 360 403 (mean (s.d.) age: 56.6 (8.0) years) participants without T2D at baseline from the UK Biobank. Genetic risk was categorised as high (highest quintile), intermediate (quintiles: 2-4), and low (lowest quintile) based on a polygenic risk score for T2D. Sleep scores, including long or short sleep duration, insomnia, snoring, late chronotype, and excessive daytime sleepiness, were categorized as an unfavourable, intermediate, or favourable sleep and circadian pattern.

RESULTS

During a median follow-up of 9.0 years, 13 120 incident T2D cases were recorded. Among the participants with an unfavourable sleep and circadian pattern, 6.96% (95% CI: 6.68-7.24%) developed T2D vs 2.37% (95% CI: 2.28-2.46%) of participants with a favourable sleep and circadian pattern (adjusted hazard ratio (HR): 1.53, 95% CI: 1.45-1.62). Of participants with a high genetic risk, 5.53% (95% CI: 5.36-5.69%) developed T2D vs 2.01% (95% CI: 1.91-2.11%) of participants with a low genetic risk (adjusted HR: 2.89, 95% CI: 2.72-3.07). The association with sleep and circadian patterns was independent of genetic risk strata. Participants in the lowest quintile with an unfavourable sleep and circadian pattern were 3.97-fold more likely to develop T2D than those in the lowest quintile with a favourable sleep and circadian pattern.

CONCLUSIONS

Sleep and circadian patterns and genetic risk were independently associated with incident T2D. These results indicate the benefits of adhering to a healthy sleep and circadian pattern in entire populations, independent of genetic risk.

Prioritizing Chinese medicine clinical research questions in cancer palliative care from patient and caregiver perspectives

BACKGROUND

Chinese medicine (CM) modalities, including acupuncture and Chinese herbal medicine (CHM), are popular palliative interventions among patients with cancer, but further clinical research is required to assess their effectiveness and safety.

OBJECTIVE

To prioritize top ten important CM clinical research questions from patients with cancer, cancer survivors and caregivers' perspectives via a face-to-face prioritization workshop in Hong Kong.

METHODS

A list of 25 CM clinical research questions for cancer palliative care, which were identified from existing systematic reviews (SRs) and overview of SRs, was presented to 17 participants (patients with cancer [n = 5], cancer survivors [n = 6] and caregivers [n = 6]). The participants were then invited to establish consensus on prioritizing top ten research questions.

RESULTS

Among the top ten priorities, five (50%) focused on acupuncture and related therapies, while five (50%) were on CHM. The three most important research priorities were (i) manual acupuncture plus opioids for relieving pain; (ii) CHM for improving quality of life among patients receiving chemotherapy; and (iii) concurrent use of CHM plus loperamide for reducing stomatitis.

CONCLUSION

The top ten participant-endorsed CM clinical research priorities for cancer palliative care can guide local researchers on future direction. They can also inform local research funders on patient-centred allocation of limited funding. Under limited research funding, the most important co-prioritized research question from professional and patient perspectives may be addressed first.

PATIENT OR PUBLIC CONTRIBUTION

Patients with cancer, cancer survivors and caregivers participated in conduct of the study to prioritize CM clinical research questions.

Designing delivery models of traditional and complementary medicine services: a review of international experiences

BACKGROUND

The World Health Organization advocates integration of traditional and complementary medicine (T&CM) into the conventional health services delivery system. Integrating quality services in a patient-centred manner faces substantial challenges when T&CM is delivered within a health system dominated by conventional medicine. This review has synthesized international experiences of integration strategies across different contexts.

SOURCES OF DATA

Publications describing international experiences of delivering T&CM service in conventional healthcare settings were searched. Backward and forward citation chasing was also conducted.

AREAS OF AGREEMENT

Capable leaders are crucial in seeking endorsement from stakeholders within the conventional medicine hierarchy and regulatory bodies. However, patient demands for integrative care can be successful as demonstrated by cases included in this review, as can the promotion of the use of T&CM for filling effectiveness gaps in conventional medicine. Safeguarding quality and safety of the services is a priority.

AREAS OF CONTROVERSY

Different referral mechanisms between conventional and T&CM practitioners suit different contexts, but at a minimum, general guideline on responsibilities across the two professionals is required. Evidence-based condition-specific referral protocols with detailed integrative treatment planning are gaining in popularity.

GROWING POINTS

Interprofessional education is critical to establishing mutual trust and understanding between conventional clinicians and T&CM practitioners. Interprofessional communication is key to a successful collaboration, which can be strengthened by patient chart sharing, instant information exchange, and dedicated time for face-to-face interactions.

AREAS TIMELY FOR DEVELOPING RESEARCH

Research is needed on the optimal methods for financing integrated care to ensure equitable access, as well as in remuneration of T&CM practitioners working in integrative healthcare.

Methodological quality of systematic reviews on treatments for osteoporosis: A cross-sectional study

PURPOSE

Systematic reviews (SRs) provide the best evidence on the effectiveness of treatment strategies for osteoporosis. Carefully conducted SRs provide high-quality evidence for supporting decision-making, but the trustworthiness of conclusions can be hampered by limitation in rigor. We aimed to appraise the methodological quality of a representative sample of SRs on osteoporosis treatments in a cross-sectional study.

METHODS

Cochrane Database of Systematic Reviews, EMBASE, MEDLINE, and PsycINFO were searched for SRs on osteoporotic treatments. AMSTAR (A MeaSurement Tool to Assess systematic Reviews) 2 was used to evaluate methodological quality of SRs. Associations between bibliographical characteristics and methodological quality ratings were explored using multivariate regression analyses.

RESULTS

A total of 101 SRs were appraised. Overall, one (1.0%) was rated "high quality", three (3.0%) were rated "moderate quality", eleven (10.9%) were rated "low quality", and eighty-six (85.1%) were rated "critically low quality". Ninety-nine (98.0%) did not explain study design selection, eighty-five (84.2%) did not provide a list of excluded studies (84.2%), and eighty-five (84.2%) did not report funding sources of included studies. SRs published in 2018 or after were associated with higher overall quality [adjusted odds ratio (AOR): 5.48; 95% confidence interval (CI): 1.12-26.89], while SRs focused on pharmacological interventions were associated with lower overall quality [AOR: 0.24; 95% CI: 0.06-0.96].

CONCLUSION

The methodological quality of the included SRs is far from satisfactory. Future reviewers must strengthen rigor by improving literature search comprehensiveness, registering and publishing a priori protocols, and optimising study selection and data extraction. Better transparency in reporting conflicts of interest among reviewers, as well as sources of funding among included primary studies, are also needed.

The use of mindfulness-based intervention to improve bracing compliance for AIS patients

Introduction

Despite good bracing compliance is crucial to prevent curve progression among braced AIS patients, only few interventions were suggested to improve bracing compliance. This study examined the effect of MBI on bracing compliance for AIS patients.

Methods

116 eligible AIS patients were randomized and 86 participants were enrolled in intervention. Patients in the MBI group joint weekly sessions, which is an adapted version of mindfulness-based stress reduction (MBSR) program, for 8 weeks. Control group consisted of an 8-week PE intervention that is recommended according to the SOSORT 2011 guideline. The primary outcome is the 6-month post-intervention bracing compliance. The secondary outcomes include quality of life and psychosocial measurements. Primary analysis was ANCOVA with treatment as covariate. Trend analysis was conducted using Linear Mixed effect model.

Results

At the end of intervention, intention-to-treat analysis improved bracing compliance by1.24h/day and 0.08h/day for MBI and PE respectively. MBI group presented an increase in emotional regulation than baseline (ERQ-CCA) (1.92, p = 0.01), especially in Cognitive reappraisal sub-scale (1.00, p = 0.05). Bracing Specific Quality of Life (SRS-22) reduced significantly in both groups, but MBI group decreased less (MBI: -3.08, p = 0.00, PE -4.47, p = 0.00). Effect at six months for compliance progressed negatively but favoured MBI group (MBI: -1.16, p = 0.13, PE: -1.84, p = 0.06) although there was no significant difference between groups (p = 0.78). The Perception of stress (PSS) decreased significantly in PE group (-3,53, p = 0.01) rather than MBI (1.53, p = 0.22), however the between-group difference isn't significant (p = 0.62).

Conclusions

It is alarming that patients in both interventions group progressed with poorer compliance and worsen QoL. These progressions were less severe in the MBI group than in the PE group, but the differences did not reach statistical significant.

Key messages

Both groups decreased in compliance and QoL but MBI group reduced less. MBI wasn't more effective in improving participants’ compliance and other measurements.

Chinese medicine diagnosis and treatment for COVID-2019: Is China ready for implementing a national guideline?

•

Chinese herbal medicine is included in the national guideline for diagnosis and treatment of COVID-19 in China, but compliance were variable.

•

Instead of national-recommended approach of individualising Chinese herbal medicine, many organizations developed their own guideline.

•

These local guidelines suggest the use of standardised herbal formulae or herbal active ingredients on all COVID-19 patients.

•

It is urgent to revise the national guideline based on preliminary outcome evaluation and consensus to attaining wider recognition.

•

National research programmes to establish clinical evidence base for Chinese herbal medicine in managing COVID-19 are urgently needed.

Objectives

COVID-19 sparked a pandemic in December 2019 and is currently posing a huge impact globally. Chinese herbal medicine is incorporated into the Chinese national guideline for COVID-19 management, emphasising the individualisation of herbal treatment guided by pattern differentiation, which is an ICD-11-endorsed approach. However, this was not widely implemented with many provincial governments and hospitals developing their own guideline, suggesting the use of standardised herbal formulae and herbal active ingredients without pattern differentiation.

Methods

Through the case study of COVID-19 guideline implementation, we compared the three approaches of developing Chinese herbal medicine, namely pattern differentiation-guided prescription, standardised herbal formulae, and herbal active ingredients, in terms of their strengths, limitations, and determinants of adoption.

Results

Pattern differentiation-guided prescription is the practice style taught in the national syllabus among universities of Traditional Chinese Medicine in China, yet the lack of relevant diagnostic research reduces its reliability and hinders its implementation. Application of standardised herbal formulae is straightforward since the majority of clinical evidence on Chinese herbal medicine is generated using this approach. Nevertheless, it is downplayed by regulatory bodies in certain jurisdictions where the use of pattern differentiation is required in routine practice. Although herbal active ingredients may have clear in vitro therapeutic mechanisms, this may not be translated into real world clinical effectiveness.

Conclusions

Multiple COVID-19 clinical trials evaluating the effectiveness and safety of Chinese herbal medicine prescribed using one of the three approaches described above are progressing. These results will demonstrate the comparative effectiveness among these approaches. Forthcoming clinical evidence from these trials should inform the updating process of the national guideline, such that its recognition and compliance may be strengthened. For longer-term development Chinese herbal medicine, serious investment for establishing high-quality clinical research infrastructure is urgently needed.

Highlights of traditional Chinese medicine frontline expert advice in the China national guideline for COVID-19

Introduction

The World Health Organization declared the coronavirus disease (COVID-19) as a pandemic on 11 March 2020, after the number of confirmed cases outside China increased 13-fold. As the epicentre of the initial outbreak, China has been updating the National COVID-19 Diagnostic and Treatment Guideline with up-to-date information about the disease. To facilitate the implementation of integrative Chinese–Western Medicine in COVID-19 management, Traditional Chinese medicine (TCM) has been recommended in recent editions of the national guideline.

Methods

The national guideline summarised the opinions and frontline experience of medical experts across the country to provide by far the best management for COVID-19. We extracted the case definition and clinical classifications of COVID-19 in China along with relevant TCM treatments cited in the seventh edition of the guideline, with an intent to disseminate practical information to TCM clinicians and researchers around the world.

Results

We present the most recent case definition, clinical classifications, and relevant TCM treatments of COVID-19 in accordance with the recommendations in the Chinese guideline. TCM treatments are stratified into two groups based on patients’ disease status. Four types of Chinese patent medicines are recommended for suspected COVID-19 cases. Several herbal formulae are recommended for confirmed COVID-19 cases according to their clinical classification and TCM pattern diagnoses. Two herbal formulae are also recommended for rehabilitation of recovering cases.

Conclusion

To control the waves of COVID-19 outbreak, countries must ensure the adherence of their citizens to local public health measures. Medical professionals should diagnose and treat patients according to up-to-date guidelines. Future evaluation of the outcomes of implementing TCM recommendations will strengthen the evidence base for COVID-19 management for the sake of public health and the internationalisation of TCM.

Prevalence and predictors of mind-body medicine use among women diagnosed with gynecological cancer: Findings from the 2017 US National Health Interview Survey

BACKGROUND

Gynecological cancer is a major health burden globally. In the US, it is common for cancer patients to utilize different types of complementary medicine. This study aims to investigate the prevalence of mind-body medicine use among US women diagnosed with gynecological cancer.

METHODS

We used data from the 2017 National Health Interview Survey (NHIS) to investigate prevalence and predictors of mind-body medicine utilization in the past 12 months among gynecological cancer patients in a representative sample of the US population (N = 26,742). We descriptively analyzed the 12-month prevalence of any mind-body medicine use, separately for women with a prior diagnosis of gynecological cancer and those without. Using and b multiple logistic regression analyses, we identified predictors of mind-body medicine use.

RESULTS

A weighted total of 2,526,369 women (2.0%) reported having received a diagnosis of gynecological cancer. More women diagnosed with gynecological cancer (weighted n = 964,098; 38.2%) than those not diagnosed with gynecological cancer (weighted mean = 36,102,852; 28.8%) had used mind-body medicine in the past 12 months. A higher prevalence of mind-body medicine use was associated with being non-Hispanic White, living in Western US and having received higher education. Spiritual meditation was found to be the most frequently used mind-body medicine modality, followed by yoga and progressive relaxation.

CONCLUSIONS

While mind-body medicine is popular among US gynecological cancer patients, clinical evidence supporting the effectiveness of different mind-body medicine modalities is yet to be established. Randomized controlled trials should be conducted to evaluate the effectiveness of popular modalities like spiritual meditation or yoga to inform clinical decision and patient choice.

Low-level laser therapy for carpal tunnel syndrome: systematic review and network meta-analysis

BACKGROUND

Splinting is recommended by various organisations as a non-surgical first-line treatment for carpal tunnel syndrome (CTS), despite the limited evidence supporting its effectiveness. Previous studies on the effectiveness of low-level laser therapy (LLLT) have reported mixed results, and this systematic review aimed to resolve this controversy.

OBJECTIVE

To perform a network meta-analysis (NMA) for evaluating the effectiveness of LLLT compared with other conservative treatments for CTS.

METHODS

Eighteen electronic databases were searched for potential randomised controlled trials (RCTs). RCTs evaluating LLLT or other non-surgical treatments as an add-on to splinting were included. Included RCTs measured at least one of the following three outcomes with validated instruments: pain, symptom severity and functional status.

RESULTS

Six RCTs (418 patients) were included. NMA suggested that LLLT plus splinting has the highest probability (75%) of pain reduction, compared with sham laser plus splinting (61%), ultrasound plus splinting (57%) and splinting alone (8%). However, while LLLT plus splinting is significantly more effective than sham laser plus splinting for pain reduction, the magnitude is not clinically significant (Visual Analogue Scale mean difference -0.53cm, 95% confidence interval -1.01 to -0.05cm; P=0.03, I²=25%). The effect of LLLT plus splinting on symptom severity and functional status was not superior to splinting alone.

CONCLUSION

The use of LLLT in addition to splinting for the management of CTS is not recommended, as LLLT offers limited additional benefits over splining alone in terms of pain reduction, reduction of symptom severity or improved functional status.

Development of Evidence-Based Chinese Medicine Clinical Service Recommendations for Cancer Palliative Care Using Delphi Approach Based on the Evidence to Decision Framework

Objectives: Existing evidence supports the use of certain Chinese medicine (CM) interventions for symptom management among palliative cancer patients. However, evidence-based service recommendations tailored to the local context are needed for CM planning and implementation. In response, we aimed to establish consensus on CM clinical service recommendations for cancer palliative care among Hong Kong experts. Methods: Seven CM interventions showing statistically significant favorable results in existing systematic reviews (SRs) and overviews of SRs were subjected to a GRADE-ADOLOPMENT-based 2-round Delphi survey. Twelve Hong Kong experts in cancer palliative care, including conventionally trained physicians, CM practitioners, and nurses (n = 4 from each category), were invited to participate. Use of the Evidence to Decision framework within the GRADE-ADOLOPMENT approach enabled experts to consider aspects of problem priority, benefits, harms, equity, acceptability, and feasibility when making CM recommendations in cancer palliative care. Results: Three evidence-based CM interventions reached positive consensus as service recommendations, namely: (1) acupuncture for reducing fatigue among palliative cancer patients; (2) acupressure for reducing fatigue among palliative cancer patients; and (3) moxibustion for reducing nausea and vomiting among patients receiving chemotherapy. Median rating of recommendation ranged from 2.5 to 3.0 (interquartile range = 0.00-1.00) on a 4-point Likert-type scale, and the percentage agreement ranged from 83.4% to 91.7%. Conclusions: The GRADE-ADOLOPMENT approach facilitates a consensus-based process of reaching 3 evidence-based CM recommendations for cancer palliative care. Future studies may develop tailored strategies to implement these recommendations in the Hong Kong health system.

Prioritizing Chinese Medicine Clinical Research Questions in Cancer Palliative Care: International Delphi Survey

CONTEXT

Chinese medicine modalities, including acupuncture and Chinese herbal medicine (CHM), have been used as palliative interventions among cancer patients. More research should be conducted to confirm their effectiveness.

OBJECTIVES

The objective of this study was to prioritize Chinese medicine clinical research questions for cancer palliative care.

METHODS

Twelve international experts, including physicians, Chinese medicine practitioners, nurses, and clinical research methodologists (n = 3 from each category), from Asia, North America, Australia, and Europe participated in a two-round Delphi survey for prioritizing 29 research questions identified from existing systematic reviews. The experts were asked to 1) rate clinical importance of answering the questions on a nine-point Likert scale; 2) provide qualitative comments on their ratings; and 3) suggest outcome measurement approaches.

RESULTS

Eight research priorities reached positive consensus after the two-round Delphi survey. Six of the priorities focused on acupuncture and related therapies, of which median ratings on importance ranged from 7.0 to 8.0 (interquartile range: 1.00 to 2.50), and the percentage agreement ranged from 75.0% to 91.7%. The remaining two priorities related to CHM, with median ratings ranged from 7.0 to 8.0 (interquartile range: 1.00 to 1.50) and percentage agreement ranged from 75.0% to 83.3%. Neither positive nor negative consensus was established among the remaining 21 questions.

CONCLUSION

The findings will inform rational allocation of scarce research funding for evaluating the effectiveness of Chinese medicine for cancer palliative care, especially on acupuncture and related therapies. Further research on herb safety and herb-drug interaction should be performed before conducting international trials on CHM.

Acupuncture and related therapies for treating irritable bowel syndrome: overview of systematic reviews and network meta-analysis

BACKGROUND

An overview of systematic reviews (SRs) and a network meta-analysis (NMA) were conducted to evaluate the comparative effectiveness of acupuncture and related therapies used either alone, or as an add-on to other irritable bowel syndrome (IBS) treatments.

METHODS

A total of eight international and Chinese databases were searched for SRs of randomized controlled trials (RCTs). The methodological quality of SRs was appraised using the AMSTAR instrument. From the included SRs, data from RCTs were extracted for the random-effect pairwise meta-analyses. An NMA was used to evaluate the comparative effectiveness of different treatment options. The risk of bias among included RCTs was assessed using the Cochrane risk of bias tool.

RESULTS

From 15 SRs of mediocre quality, 27 eligible RCTs (n = 2141) were included but none performed proper blinding. Results from pairwise meta-analysis showed that both needle acupuncture and electroacupuncture were superior in improving global IBS symptoms when compared with pinaverium bromide. NMA results showed needle acupuncture plus Geshanxiaoyao formula had the highest probability of being the best option for improving global IBS symptoms among 14 included treatment options, but a slight inconsistency exists.

CONCLUSION

The risk of bias and NMA inconsistency among included trials limited the trustworthiness of the conclusion. Patients who did not respond well to first-line conventional therapies or antidepressants may consider acupuncture as an alternative. Future trials should investigate the potential of (1) acupuncture as an add-on to antidepressants and (2) the combined effect of Chinese herbs and acupuncture, which is the norm of routine Chinese medicine practice.

Chinese herbal medicine for functional dyspepsia: systematic review of systematic reviews

BACKGROUND

Pharmacotherapy, including prokinetics and proton pump inhibitors for functional dyspepsia (FD) have limited effectiveness, and their safety has been recently questioned. Chinese herbal medicine (CHM) could be considered as an alternative. A systematic review (SR) of SRs was performed to evaluate the potential effectiveness and safety of CHM.

METHOD

We conducted a comprehensive literature search for SRs with meta-analyses in eight international and Chinese databases. Pooled effect estimation from each meta-analysis was extracted. The AMSTAR instrument was used to assess the methodological quality of the included SRs.

RESULTS

A total of 14 SRs of mediocre quality assessing various CHMs, alone or in combination with conventional pharmacotherapy, were included. Meta-analyses showed that CHM was more effective than prokinetic agents for the alleviation of global dyspeptic symptoms. Three specific CHM formulae appeared to show superior results in the alleviation of global dyspeptic symptoms, including Si Ni San, modified Xiao Yao San and Xiang Sha Liu Jun Zi decoction. No significant difference in the occurrence of adverse events in using CHM or pharmacotherapy was reported.

CONCLUSION

CHM can be considered as an alternative for the treatment of FD symptoms when prokinetic agents and proton pump inhibitors are contraindicated. Future trial design should focus on measuring changes in individual dyspeptic symptoms and differentiate the effectiveness of different CHM for postprandial distress syndrome and epigastric pain syndrome. A network meta-analysis approach should be used to explore the most promising CHM formula for FD treatment in the future.

Effectiveness of smartphone technologies on glycaemic control in patients with type 2 diabetes: systematic review with meta-analysis of 17 trials

Patient education and behavioural interventions for self-management of type 2 diabetes mellitus (T2DM) are effective but place demands on manpower resources. This systematic review aimed to investigate the effectiveness of smartphone technologies (STs) for improving glycaemic control among T2DM patients. CENTRAL, MEDLINE, Embase, CINAHL and ScienceDirect were searched through December 2016. Randomized controlled trials comparing STs with usual diabetes care among T2DM patients and reporting change in glycated haemoglobin (HbA1c) level were included. Seventeen trials (2,225 participants) were included. There was a significant reduction in HbA1c (pooled weighted mean difference: -0.51%; 95% confidence interval: -0.71% to -0.30%; p < 0.001), favouring ST intervention. The pooled weighted mean difference was -0.83% in patients with T2DM <8.5 years and -0.22% in patients with T2DM ≥8.5 years, with significant subgroup difference (p = 0.007). No subgroup differences were found among different follow-up durations, trial locations, patients' age, healthcare provider contract time, baseline body mass index and baseline HbA1c. Compared with usual diabetes care, STs improved glycaemic control among T2DM patients, especially for patients at earlier disease stages (duration of diagnosis <8.5 years). STs could be a complement or alternative to labour-intensive patient education and behavioural interventions, but more studies on up-to-date technologies are needed.

Electroacupuncture plus standard of care for managing refractory functional dyspepsia: protocol of a pragmatic trial with economic evaluation

INTRODUCTION

This trial proposes to compare the effectiveness and cost-effectiveness of electroacupuncture (EA) plus on-demand gastrocaine with waiting list for EA plus on-demand gastrocaine in providing symptom relief and quality-of-life improvement among patients with functional dyspepsia (FD).

METHODS AND ANALYSIS

This is a single-centre, pragmatic, randomised parallel-group, superiority trial comparing the outcomes of (1) EA plus on-demand gastrocaine group and (2) waiting list to EA plus on-demand gastrocaine group. 132 (66/arm) endoscopically confirmed, Helicobacter pylori-negative patients with FD will be recruited. Enrolled patients will respectively be receiving (1) 20 sessions of EA over 10 weeks plus on-demand gastrocaine; or (2) on-demand gastrocaine and being nominated on to a waiting list for EA, which entitles them 20 sessions of EA over 10 weeks after 12 weeks of waiting. The primary outcome will be the between-group difference in proportion of patients achieving adequate relief of symptoms over 12 weeks. The secondary outcomes will include patient-reported change in global symptoms and individual symptoms, Nepean Dyspepsia Index, Nutrient Drink Test, 9-item Patient Health Questionnaire (PHQ9), and 7-item Generalised Anxiety Disorder Scale (GAD7). Adverse events will be assessed formally. Results on direct medical costs and on the EuroQol (EQ-5D) questionnaire will also be used to assess cost-effectiveness. Analysis will follow the intention-to-treat principle using appropriate univariate and multivariate methods. A mixed model analysis taking into account missing data of these outcomes will be performed. Cost-effectiveness analysis will be performed using established approach.

ETHICS AND DISSEMINATION

The study is supported by the Health and Medical Research Fund, Government of the Hong Kong Special Administrative Region of China. It has been approved by the Joint Chinese University of Hong Kong - New Territories East Cluster Clinical Research Ethics Committee. Results will be published in peer-reviewed journals and be disseminated in international conference.

Integrated care for older populations and its implementation facilitators and barriers: A rapid scoping review

Purpose

Inform health system improvements by summarizing components of integrated care in older populations. Identify key implementation barriers and facilitators.

Data sources

A scoping review was undertaken for evidence from MEDLINE, the Cochrane Library, organizational websites and internet searches. Eligible publications included reviews, reports, individual studies and policy documents published from 2005 to February 2017.

Study selection

Initial eligible documents were reviews or reports concerning integrated care approaches in older/frail populations. Other documents were later sourced to identify and contextualize implementation issues.

Data extraction

Study findings and implementation barriers and facilitators were charted and thematically synthesized.

Results of data synthesis

Thematic synthesis using 30 publications identified 8 important components for integrated care in elderly and frail populations: (i) care continuity/transitions; (ii) enabling policies/governance; (iii) shared values/goals; (iv) person-centred care; (v) multi-/inter-disciplinary services; (vi) effective communication; (vii) case management; (viii) needs assessments for care and discharge planning. Intervention outcomes and implementation issues (barriers or facilitators) tend to depend heavily on the context and programme objectives. Implementation issues in four main areas were observed: (i) Macro-level contextual factors; (ii) Miso-level system organization (funding, leadership, service structure and culture); (iii) Miso-level intervention organization (characteristics, resources and credibility) and (iv) Micro-level factors (shared values, engagement and communication).

Conclusion

Improving integration in care requires many components. However, local barriers and facilitators need to be considered. Changes are expected to occur slowly and are more likely to be successful where elements of integrated care are well incorporated into local settings.

Acupuncture and related therapies used as add-on or alternative to prokinetics for functional dyspepsia: overview of systematic reviews and network meta-analysis

Prokinetics for functional dyspepsia (FD) have relatively higher number needed to treat values. Acupuncture and related therapies could be used as add-on or alternative. An overview of systematic reviews (SRs) and network meta-analyses (NMA) were performed to evaluate the comparative effectiveness of different acupuncture and related therapies. We conducted a comprehensive literature search for SRs of randomized controlled trials (RCTs) in eight international and Chinese databases. Data from eligible RCTs were extracted for random effect pairwise meta-analyses. NMA was used to explore the most effective treatment among acupuncture and related therapies used alone or as add-on to prokinetics, compared to prokinetics alone. From five SRs, 22 RCTs assessing various acupuncture and related therapies were included. No serious adverse events were reported. Two pairwise meta-analyses showed manual acupuncture has marginally stronger effect in alleviating global FD symptoms, compared to domperidone or itopride. Results from NMA showed combination of manual acupuncture and clebopride has the highest probability in alleviating patient reported global FD symptom. Combination of manual acupuncture and clebopride has the highest probability of being the most effective treatment for FD symptoms. Patients who are contraindicated for prokinetics may use manual acupuncture or moxibustion as alternative. Future confirmatory comparative effectiveness trials should compare clebopride add-on manual acupuncture with domperidone add-on manual acupuncture and moxibustion.

Complementary and Alternative Medicine Use Among US Adults With Headache or Migraine: Results from the 2012 National Health Interview Survey

BACKGROUND

Given the safety concerns regarding pharmacological agents, and the considerable impact of headache and migraine on the sufferer's quality of life, many people seek other treatment options beyond conventional medication and care to address their symptoms; this includes complementary and alternative medicine (CAM). Some CAM interventions have shown promising results in clinical trials of headache and migraine management. Nonetheless, there has been little research exploring the reasons for using CAM, and the types of CAM used, among this population.

OBJECTIVE

The study aimed to answer the following questions: (1) Which CAM modalities are used most frequently among migraine/headache sufferers? and (2) What are the self-reported reasons for CAM use among migraine/headache sufferers?

METHODS

This secondary analysis of data from the 2012 U.S. NHIS (a national cross-sectional survey) examined the use of CAM among migraine/headache sufferers, including the main reasons related to CAM use. Data were weighted and analyzed using STATA 14.0.

RESULTS

The sample of 34,525 adults included 6558 (18.7%) headache/migraine sufferers. Of the headache/migraine sufferers, a substantial proportion (37.6%, n = 2427) used CAM for various conditions; however, CAM use specifically for headache/migraine was much less prevalent (3.3%, n = 216). Of those who used CAM for headache/migraine, about half used CAM in conjunction with prescription (47.8%, n = 100) or over-the-counter medication (55.1%, n = 113). As severity of headache/migraine increased so did the likelihood of using CAM (severe migraine odds ratio [OR] = 2.32; 95% confidence interval [CI]: 1.41, 3.82; both recurring headache/severe migraine OR = 3.36; 95% CI: 2.08, 5.43; when compared to those with recurring headache only). The most frequently used CAM modality among all headache/migraine sufferers (N = 6558) was manipulative therapy (22.0%, n = 1317), herbal supplementation (21.7%, n = 1389) and mind-body therapy (17.9%, n = 1100). The top 3 reasons for using CAM for headache were general wellness (28.7%, n = 60/209), improving overall health (26.8%, n = 56/209), and reducing stress (16.7%, n = 35/209).

CONCLUSIONS

Although CAM is used by many sufferers of headache/migraine, the use of CAM specifically for the treatment of headache/migraine is relatively low in the United States. The study also assesses the key differences of CAM use among headache/migraine sufferers in NHIS 2012 compared with those in NHIS 2007, and identifies shortfalls in the evidence-base of several CAM modalities used by U.S. adults for headache/migraine. This information may assist health providers and consumers in making informed decisions about the safest and most appropriate approach to managing headache/migraine.

A Pilot Cross-Sectional Study of Postpartum Wrist Pain in an Urban Chinese Population: Its Prevalence and Risk Factors

BACKGROUND

Wrist pain after childbirth is commonly encountered in clinical practice. Little is known about the prevalence of this musculoskeletal disorder which is important to overall maternal health.

OBJECTIVE

To examine the prevalence of and risk factors for de novo wrist pain in women after childbirth.

STUDY DESIGN

A pilot cross-sectional survey.

SETTING

A telephone interview was conducted 2 months after childbirth among women who delivered at a tertiary hospital in Hong Kong.

METHODS

The prevalence of de novo wrist pain was recorded; its severity was rated using the numerical rating scale and Patient-Rated Wrist Evaluation (PRWE) with pain and functional subscale scores.

RESULTS

In total, 259 women aged 32.8 ± 4.0 years participated; 149 women (57.5%) developed wrist pain after childbirth and 125 (84%) had persistent wrist pain 2 months postpartum. The majority had moderate (43.5%) to severe (21%) wrist pain. Bilateral involvement was common (56.8%), with most of the pain (59.3%) located on the radial side of the wrist. Primiparity was associated with wrist pain development (odds ratio 2.62, 95% confidence interval 1.33 - 5.16, P = 0.01); pain intensity was negatively correlated with the baby's birth weight (beta = -1.059, P = 0.013). Mean PRWE pain and function scores were 22.8 ± 10.3 and 15.6 ± 10.7, respectively.

LIMITATIONS

Cross-sectional survey is prone to volunteer bias, though recent literature indicates that the bias may not substantially affect the internal validity of the study.

CONCLUSIONS

Wrist pain is prevalent after childbirth; future studies may consider looking into its exact pathology, long-term consequences, and overall effect on maternal health.

KEY WORDS

Wrist pain, DeQuervain disease, postpartum, childbirth, mothers, prevalence, cross sectional study, survey.

Care Toward the End of Life in Older Populations and Its Implementation Facilitators and Barriers: A Scoping Review

PURPOSE

To inform health system improvements for care of elderly populations approaching the end of life (EOL) by identifying important elements of care and implementation barriers and facilitators.

DESIGN

A scoping review was carried out to identify key themes in EOL care. Articles were identified from MEDLINE, the Cochrane Library, organizational websites, and internet searches. Eligible publications included reviews, reports, and policy documents published between 2005 and 2016. Initially, eligible documents included reviews or reports concerning effective or important models or components of EOL care in older populations, and evidence was thematically synthesized. Later, other documents were identified to contextualize implementation issues.

RESULTS

Thematic synthesis using 35 reports identified key features in EOL care: (1) enabling policies and environments; (2) care pathways and models; (3) assessment and prognostication; (4) advance care planning and advance directives; (5) palliative and hospice care; (6) integrated and multidisciplinary care; (7) effective communication; (8) staff training and experience; (9) emotional and spiritual support; (10) personalized care; and (11) resources. Barriers in implementing EOL care include fragmented services, poor communication, difficult prognostication, difficulty in accepting prognosis, and the curative focus in medical care.

CONCLUSIONS

Quality EOL care for older populations requires many core components but the local context and implementation issues may ultimately determine if these elements can be incorporated into the system to improve care. Changes at the macro-level (system/national), meso-level (organizational), and micro-level (individual) will be required to successfully implement service changes to provide holistic and person-centered EOL care for elderly populations.

Epidemiological characteristics and methodological quality of meta-analyses on diabetes mellitus treatment: a systematic review

OBJECTIVE

Well-conducted meta-analyses (MAs) are considered as one of the best sources of clinical evidence for treatment decision. MA with methodological flaws may introduce bias and mislead evidence users. The aim of this study is to investigate the characteristics and methodological quality of MAs on diabetes mellitus (DM) treatments.

DESIGN

Systematic review.

METHODS

Cochrane Database of Systematic Review and Database of Abstract of Reviews of Effects were searched for relevant MAs. Assessing methodological quality of systematic reviews (AMSTAR) tool was used to evaluate the methodological quality of included MAs. Logistic regression analysis was used to identify association between characteristics of MA and AMSTAR results.

RESULTS

A total of 252 MAs including 4999 primary studies and 13,577,025 patients were included. Over half of the MAs (65.1%) only included type 2 DM patients and 160 MAs (63.5%) focused on pharmacological treatments. About 89.7% MAs performed comprehensive literature search and 89.3% provided characteristics of included studies. Included MAs generally had poor performance on the remaining AMSTAR items, especially in assessing publication bias (39.3%), providing lists of studies (19.0%) and declaring source of support comprehensively (7.5%). Only 62.7% MAs mentioned about harm of interventions. MAs with corresponding author from Asia performed less well in providing MA protocol than those from Europe.

CONCLUSIONS

Methodological quality of MA on DM treatments was unsatisfactory. There is considerable room for improvement, especially in assessing publication bias, providing lists of studies and declaring source of support comprehensively. Also, there is an urgent need for MA authors to report treatment harm comprehensively.

Electroacupuncture and splinting versus splinting alone to treat carpal tunnel syndrome: a randomized controlled trial

BACKGROUND

The effectiveness of acupuncture for managing carpal tunnel syndrome is uncertain, particularly in patients already receiving conventional treatments (e.g., splinting). We aimed to assess the effects of electroacupuncture combined with splinting.

METHODS

We conducted a randomized parallel-group assessor-blinded 2-arm trial on patients with clinically diagnosed primary carpal tunnel syndrome. The treatment group was offered 13 sessions of electroacupuncture over 17 weeks. The treatment and control groups both received continuous nocturnal wrist splinting.

RESULTS

Of 181 participants randomly assigned to electroacupuncture combined with splinting (n = 90) or splinting alone (n = 91), 174 (96.1%) completed all follow-up. The electroacupuncture group showed greater improvements at 17 weeks in symptoms (primary outcome of Symptom Severity Scale score mean difference [MD] -0.20, 95% confidence interval [CI] -0.36 to -0.03), disability (Disability of Arm, Shoulder and Hand Questionnaire score MD -6.72, 95% CI -10.9 to -2.57), function (Functional Status Scale score MD -0.22, 95% CI -0.38 to -0.05), dexterity (time to complete blinded pick-up test MD -6.13 seconds, 95% CI -10.6 to -1.63) and maximal tip pinch strength (MD 1.17 lb, 95% CI 0.48 to 1.86). Differences between groups were small and clinically unimportant for reduction in pain (numerical rating scale -0.70, 95% CI -1.34 to -0.06), and not significant for sensation (first finger monofilament test -0.08 mm, 95% CI -0.22 to 0.06).

INTERPRETATION

For patients with primary carpal tunnel syndrome, chronic mild to moderate symptoms and no indication for surgery, electroacupuncture produces small changes in symptoms, disability, function, dexterity and pinch strength when added to nocturnal splinting.

Use of Traditional and Complementary Medicine as Self-Care Strategies in Community Health Centers: Cross-Sectional Study in Urban Pearl River Delta Region of China

In China, Community Health Centers (CHCs) are major providers of primary care services, but their potential in empowering patients' self-management capacity has not been assessed. This study aims to describe self-care practice patterns amongst CHC attendees in urban China.In this cross-sectional quantitative study, 3360 CHC patients from 6 cities within the Pearl Delta Region were sampled using multistage cluster sampling.Thirty-seven per cent had used with over-the-counter Chinese herbal medicines (OTC CHMs) in the past year and majority of respondents found OTC CHMs effective. OTC CHMs were more popular amongst those who needed to pay out of pocket for CHC services. Less than 10% used vitamins and minerals, and those with a lower socioeconomic background have a higher propensity to consume. Although doubts on their usefulness are expressed, their use by the vulnerable population may reflect barriers to access to conventional health care, cultural affinity, or a defense against negative consequences of illnesses. About 25% performed physical exercise, but the prevalence is lower amongst women and older people. Taiji seems to be an alternative for these populations with promising effectiveness, but overall only 6% of CHC attendees participated.These results suggest that CHCs should start initiatives in fostering appropriate use of OTC CHM, vitamins, and minerals. Engaging community pharmacists in guiding safe and effective use of OTC CHM amongst the uninsured is essential given their low accessibility to CHC services. Prescription of Taiji instead of physical exercises to women and older people could be more culturally appropriate, and the possibility of including this as part of the CHC services worth further exploration.

Chinese Herbal Medicine and Salmeterol and Fluticasone Propionate for Chronic Obstructive Pulmonary Disease: Systematic Review and Network Meta-Analysis

Among Chinese populations worldwide, Chinese herbal medicines (CHMs) are often used as an adjunct to pharmacotherapy in managing chronic obstructive pulmonary disease (COPD). However, the relative performance among different CHM is unknown.The aim of this study was to evaluate comparative effectiveness of different CHM when used with salmeterol and fluticasone propionate (SFP), compared with SFP alone.This study is a systematic review of randomized controlled trials (RCTs) with network meta-analyses (NMAs).Eight electronic databases were searched. Data from RCTs were extracted for random effect pairwise meta-analyses. Pooled relative risk (RR) with 95% confidence interval (CI) was used to quantify the impact of CHM and SFP on forced expiratory volume in 1 second (FEV1), St George's Respiratory Questionnaire (SGRQ) scoring, and 6-Minute Walk Test (6MWT). NMA was used to explore the most effective CHM when used with SFP.Eleven RCTs (n = 925) assessing 11 different CHM were included. Result from pairwise meta-analyses indicated favorable, clinically relevant benefit of CHM and SFP on FEV1 [7 studies, pooled weighted mean difference (WMD) = 0.20 L, 95% CI: 0.06-0.34 L], SGRQ scoring (5 studies, pooled WMD = -4.99, 95% CI: -7.73 to -2.24), and 6MWT (3 studies, pooled WMD = 32.84 m, 95% CI: 18.26-47.42). Results from NMA showed no differences on the comparative effectiveness among CHM formulations for improving FEV1. For SGRQ, NMA suggested that Runfeijianpibushen decoction and Renshenbufei pills performed best. Use of CHM on top of SFP can provide clinically relevant benefit for COPD patients on FEV1 and SGRQ. Additional use of Runfeijianpibushen decoction and Renshenbufei pills showed better effect on improving SGRQ.Use of CHM and SFP may provide clinically relevant benefit for COPD patients on FEV1, SGRQ, and 6MWT. Use of different CHM formulae included in this NMA showed similar effect for increasing FEV1, while the additional use of Runfeijianpibushen formula and Renshenbufei Pills showed better effect on improving SGRQ. Well conducted, adequately powered trials are needed to confirm their effectiveness in the future.

Patient Perceptions of Expression of Empathy From Chinese Medicine Clinicians in a Chinese Population: A Cross-Sectional Study

This study aims to examine the level of empathy perceived by patients receiving care from herbalists, acupuncturists and massage therapists and to investigate the factors that influence levels of perceived empathy.Participants who were 18 years or above; able to provide written informed consent; and able to read and write in Chinese without assistance were included. A total of 514 participants sampled from charity and semipublic Chinese medicine (CM) clinics in Hong Kong were recruited to assess levels of empathy perceived during various length of consultations (1-20 minutes) by the Chinese Consultation and Relational Empathy Measure (Chinese CARE). Multiple linear regressions were conducted to evaluate the associations between perceived levels of empathy and the type of CM practitioner consulted and participants' demographic and health characteristics.The average Chinese CARE total score for participants consulting CM practitioners was 34.3 of a maximum of 50. After adjusting for participants' health and demographic characteristics, acupuncturists received the highest ratings (P < 0.001), whereas massage therapists (P < 0.001) scored the lowest of the 3 modalities. Participants receiving social benefits (P = 0.013), those with longer waiting times (P = 0.002), and those with shorter consultation durations (P = 0.020) scored significantly lower on the Chinese CARE.The level of empathy perceived by participants using CM was similar to results found for those in conventional care, in contrast to findings in other geographical settings, where a high level of perceived empathy was a major motivator for participants to choose complementary medicine.

Acupuncture and Related Therapies for Symptom Management in Palliative Cancer Care: Systematic Review and Meta-Analysis

Available systematic reviews showed uncertainty on the effectiveness of using acupuncture and related therapies for palliative cancer care. The aim of this systematic review and meta-analysis was to summarize current best evidence on acupuncture and related therapies for palliative cancer care. Five international and 3 Chinese databases were searched. Randomized controlled trials (RCTs) comparing acupuncture and related therapies with conventional or sham treatments were considered. Primary outcomes included fatigue, paresthesia and dysesthesias, chronic pain, anorexia, insomnia, limb edema, constipation, and health-related quality of life, of which effective conventional interventions are limited. Thirteen RCTs were included. Compared with conventional interventions, meta-analysis demonstrated that acupuncture and related therapies significantly reduced pain (2 studies, n = 175, pooled weighted mean difference: -0.76, 95% confidence interval: -0.14 to -0.39) among patients with liver or gastric cancer. Combined use of acupuncture and related therapies and Chinese herbal medicine improved quality of life in patients with gastrointestinal cancer (2 studies, n = 111, pooled standard mean difference: 0.75, 95% confidence interval: 0.36-1.13). Acupressure showed significant efficacy in reducing fatigue in lung cancer patients when compared with sham acupressure. Adverse events for acupuncture and related therapies were infrequent and mild. Acupuncture and related therapies are effective in reducing pain, fatigue, and in improving quality of life when compared with conventional intervention alone among cancer patients. Limitations on current evidence body imply that they should be used as a complement, rather than an alternative, to conventional care. Effectiveness of acupuncture and related therapies for managing anorexia, reducing constipation, paresthesia and dysesthesia, insomnia, and limb edema in cancer patients is uncertain, warranting future RCTs in these areas.

Chinese Herbal Medicine for Symptom Management in Cancer Palliative Care: Systematic Review And Meta-analysis

Use of Chinese herbal medicines (CHM) in symptom management for cancer palliative care is very common in Chinese populations but clinical evidence on their effectiveness is yet to be synthesized. To conduct a systematic review with meta-analysis to summarize results from CHM randomized controlled trials (RCTs) focusing on symptoms that are undertreated in conventional cancer palliative care.Five international and 3 Chinese databases were searched. RCTs evaluating CHM, either in combination with conventional treatments or used alone, in managing cancer-related symptoms were considered eligible. Effectiveness was quantified by using weighted mean difference (WMD) using random effect model meta-analysis. Fourteen RCTs were included. Compared with conventional intervention alone, meta-analysis showed that combined CHM and conventional treatment significantly reduced pain (3 studies, pooled WMD: -0.90, 95% CI: -1.69 to -0.11). Six trials comparing CHM with conventional medications demonstrated similar effect in reducing constipation. One RCT showed significant positive effect of CHM plus chemotherapy for managing fatigue, but not in the remaining 3 RCTs. The additional use of CHM to chemotherapy does not improve anorexia when compared to chemotherapy alone, but the result was concluded from 2 small trials only. Adverse events were infrequent and mild. CHM may be considered as an add-on to conventional care in the management of pain in cancer patients. CHM could also be considered as an alternative to conventional care for reducing constipation. Evidence on the use of CHM for treating anorexia and fatigue in cancer patients is uncertain, warranting further research.

Chinese Herbal Medicine for Improving Quality of Life Among Nonsmall Cell Lung Cancer Patients: Overview of Systematic Reviews and Network Meta-Analysis

For patients with nonsmall cell lung cancer (NSCLC) receiving chemotherapy, current clinical evidence has indicated add-on benefit of Chinese herbal medicine (CHM) in improving quality of life (QoL). However, the relative performance among different CHM is unknown. The aim of this overview of systematic reviews (SRs) and network meta-analyses (NMA) is to evaluate the comparative effectiveness of different CHM. Seven electronic databases including both international databases and Chinese databases were searched. SRs focus on randomized controlled trials (RCTs) with comparison of CHM plus chemotherapy against chemotherapy alone on QoL among NSCLC patients were considered eligible. Data from RCTs were extracted for random effect pairwise meta-analyses. Pooled relative risk (RR) with 95% confidence interval (CI) was used to quantify the impact of CHM on QoL. NMA was used to explore the most effective CHM for improving QoL when used with chemotherapy. From 14 SRs, 61 RCTs (n = 4247) assessing 11 different CHM were included. Result from pairwise meta-analyses showed 6 CHM (Kang-lai-te injection, Shei-qi-fu-zheng injection, Compound ku-shen injection, Kang-ai injection, Zi-jin-long tablet, and Shen-fu injection) has significant beneficial effect on QoL among NSCLC patients when used with chemotherapy, even after adjustment for publication bias. Pooled RR varied from 1.38 (95% CI: 1.11-1.72, I2 = 0.0%, Kang-lai-te injection) to 3.36 (95% CI: 1.30-8.66, I2 = 0.0%, Zi-jin-long tablet). One trial comparing Hai-shen-su (a protein extract from Tegillarca granosa L.) plus chemotherapy with chemotherapy also demonstrated beneficial effect of combined treatment (RR = 3.13, 95% CI: 1.41-6.98). Results from NMA showed no differences on the comparative effectiveness among CHM, but Hai-shen-su plus chemotherapy has the highest probability (62.3%) of being the best option for improving QoL. Use of CHM on top of chemotherapy can significantly improve QoL in NSCLC patients. Although Hai-shen-su showed the highest probability of being the best add-on to chemotherapy, the effectiveness of all 11 CHM reviewed appeared to be similar. In the future, rigorous placebo controlled trials with proper blinding are needed to confirm the effectiveness of CHM.

Effectiveness of acupuncture and related therapies for palliative care of cancer: overview of systematic reviews

Acupuncture and related therapies such as moxibustion and transcutaneous electrical nerve stimulation are often used to manage cancer-related symptoms, but their effectiveness and safety are controversial. We conducted this overview to summarise the evidence on acupuncture for palliative care of cancer. Our systematic review synthesised the results from clinical trials of patients with any type of cancer. The methodological quality of the 23 systematic reviews in this overview, assessed using the Methodological Quality of Systematic Reviews Instrument, was found to be satisfactory. There is evidence for the therapeutic effects of acupuncture for the management of cancer-related fatigue, chemotherapy-induced nausea and vomiting and leucopenia in patients with cancer. There is conflicting evidence regarding the treatment of cancer-related pain, hot flashes and hiccups, and improving patients' quality of life. The available evidence is currently insufficient to support or refute the potential of acupuncture and related therapies in the management of xerostomia, dyspnea and lymphedema and in the improvement of psychological well-being. No serious adverse effects were reported in any study. Because acupuncture appears to be relatively safe, it could be considered as a complementary form of palliative care for cancer, especially for clinical problems for which conventional care options are limited.

Tong-xin-luo capsule for patients with coronary heart disease after percutaneous coronary intervention

BACKGROUND

Percutaneous coronary intervention (PCI) is a standard treatment for coronary heart disease (CHD). Restenosis, defined as a 50% reduction in luminal diameter at six months after PCI, indicates a need for revascularisation. Restenosis has proven to be a major drawback to PCI. Tong-xin-luo is one of the prophylactic strategies for cardiovascular events in patients after PCI that is widely used in China, but its efficacy and safety have not been systematically evaluated.

OBJECTIVES

To systematically assess the efficacy and safety of Tong-xin-luo capsules in preventing cardiovascular events after PCI in patients with CHD.

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials in The Cochrane Library, MEDLINE (OVID), EMBASE (OVID), WanFang, Chinese Biomedical Database, Chinese Medical Current Contents, and China National Knowledge Infrastructure from their inception to June 2014. We also searched other resources, including ongoing trials and research registries. We applied no language restrictions.

SELECTION CRITERIA

Randomised controlled trials of participants with CHD after PCI were included. Participants in the intervention group received Tong-xin-luo capsules for at least three months.

DATA COLLECTION AND ANALYSIS

Two review authors independently extracted data and assessed the risk of bias. Any disagreements were resolved by discussion with a third review author. The primary outcomes included occurrence of angiographic restenosis and adverse events; the secondary outcomes included myocardial infarction, heart failure, angina, all cause mortality, mortality due to any cardiovascular event, use of revascularisation, patient acceptability, quality of life and cost-effectiveness. Dichotomous data were measured with risk ratios (RRs) with 95% confidence intervals (CIs).

MAIN RESULTS

Sixteen studies involving 1063 participants were identified. The risk of bias for fifteen studies was high and along with imprecision and possible publication bias, this lowered our confidence in the results. There was low quality evidence that Tong-xi-luo reduced the rates of angiographic restenosis (RR 0.16, 95% CI 0.07 to 0.34), myocardial infarction (RR 0.32, 95% CI 0.16 to 0.66), heart failure (RR 0.26, 95% CI 0.11 to 0.62), and use of revascularisation (RR 0.26, 95% CI 0.15 to 0.45). There was very low quality evidence for the effect of Tong-xin-luo on all-cause mortality (RR 0.38, 95% CI 0.06 to 2.56), angina (RR 0.24, 95% CI 0.17 to 0.34) and death due to any cardiovascular event (RR 0.31, 95% CI 0.08 to 1.12). Adverse events were seldom reported, and included gastrointestinal reactions and nausea.

AUTHORS' CONCLUSIONS

The addition of Tong-xin-luo to conventional Western medicine may possibly prevent restenosis and recurrence of cardiovascular events in patients with CHD after PCI. However, the data are limited by publication bias and high risk of bias for included studies. Further high-quality trials are required to evaluate the potential effects of this intervention.

Are meta-analyses of Chinese herbal medicine trials trustworthy and clinically applicable? A cross-sectional study

ETHNOPHARMACOLOGICAL RELEVANCE

Meta-analysis (MA) on Chinese herbal medicine (CHM) trials is increasingly published and indexed in major international databases but their trustworthiness and clinical applicability is uncertain. We aimed to assess the characteristics and methodological quality of MA on CHM.

MATERIALS AND METHODS

Cross-sectional study. MA published during 1993-2013 was sampled from MEDLINE, EMBASE, Cochrane Database of Systematic Reviews and Database of Abstracts of Reviews of Effect. Bibliographical characteristics were abstracted and methodological quality was assessed using the validated AMSTAR tool by two independent reviewers.

RESULTS

Total of 201 MA were included and half were published in or after 2009. Only 7.5% being updates of previous reviews. Majority are published in journals with low or no impact factor, with a median of 1.5. These MA demonstrated methodological strengths in ensuring comprehensive literature search, providing characteristics of the included studies, assessing the scientific quality of included studies and appropriately using the scientific quality of included studies in formulating conclusions. Nevertheless, weaknesses in protocol provision, listing of included and excluded studies, inclusion of grey literature, use of appropriate meta-analytic technique as well as reporting of funding sources were prevalent. CHM and control interventions pooled in majority of MA are found to have substantial clinical heterogeneity in terms of composition, dosage form and route of administration.

CONCLUSIONS

There are rooms for improvement in methodological rigor, and in choosing clinically homogenous interventions and control for statistical pooling. These shortcomings limit the trustworthiness and clinical applicability of existing MA on CHM trials. To overcome the limitations of pair-wise meta-analysis in synthesizing trials comparing different CHM and control interventions, the potential of network meta-analysis should be explored.

Is Alcohol Use Disorder Identification Test (AUDIT) or its shorter versions more useful to identify risky drinkers in a Chinese population? A diagnostic study

Objective

To examine the diagnostic performance of shorter versions of Alcohol Use Disorder Identification Test (AUDIT), including Alcohol Consumption (AUDIT-C), in identifying risky drinkers in primary care settings using conventional performance measures, supplemented by decision curve analysis and reclassification table.

Study design and Setting

A cross-sectional study of adult males in general outpatient clinics in Hong Kong. The study included only patients who reported at least sometimes drinking alcoholic beverages. Timeline follow back alcohol consumption assessment method was used as the reference standard. A Chinese translated and validated 10-item AUDIT (Ch-AUDIT) was used as a screening tool of risky drinking.

Results

Of the participants, 21.7% were classified as risky drinkers. AUDIT-C has the best overall performance among the shorter versions of Ch-AUDIT. The AUC of AUDIT-C was comparable to Ch-AUDIT (0.898 vs 0.901, p-value = 0.959). Decision curve analysis revealed that when the threshold probability ranged from 15–30%, the AUDIT-C had a higher net-benefit than all other screens. AUDIT-C improved the reclassification of risky drinking when compared to Ch-AUDIT (net reclassification improvement = 0.167). The optimal cut-off of AUDIT-C was at ≥5.

Conclusion

Given the rising levels of alcohol consumption in the Chinese regions, this Chinese translated 3-item instrument provides convenient and time-efficient risky drinking screening and may become an increasingly useful tool.

Methodological quality of meta-analyses on treatments for chronic obstructive pulmonary disease: a cross-sectional study using the AMSTAR (Assessing the Methodological Quality of Systematic Reviews) tool

Background:

Meta-analysis (MA) of randomised trials is considered to be one of the best approaches for summarising high-quality evidence on the efficacy and safety of treatments. However, methodological flaws in MAs can reduce the validity of conclusions, subsequently impairing the quality of decision making.

Aims:

To assess the methodological quality of MAs on COPD treatments.

Methods:

A cross-sectional study on MAs of COPD trials. MAs published during 2000–2013 were sampled from the Cochrane Database of Systematic Reviews and Database of Abstracts of Reviews of Effect. Methodological quality was assessed using the validated AMSTAR (Assessing the Methodological Quality of Systematic Reviews) tool.

Results:

Seventy-nine MAs were sampled. Only 18% considered the scientific quality of primary studies when formulating conclusions and 49% used appropriate meta-analytic methods to combine findings. The problems were particularly acute among MAs on pharmacological treatments. In 48% of MAs the authors did not report conflict of interest. Fifty-eight percent reported harmful effects of treatment. Publication bias was not assessed in 65% of MAs, and only 10% had searched non-English databases.

Conclusions:

The methodological quality of the included MAs was disappointing. Consideration of scientific quality when formulating conclusions should be made explicit. Future MAs should improve on reporting conflict of interest and harm, assessment of publication bias, prevention of language bias and use of appropriate meta-analytic methods.
