Health and care workers in long-term care facilities and their role in preventing emerging infectious diseases: A scoping review.

BACKGROUND: The COVID-19 pandemic has had a tremendous impact on healthcare systems worldwide. In particular, long-term care facilities have proved more susceptible to infection as they care for vulnerable populations at high risk of chronic illness. How this impacts the role and core competencies of health and care workers in these facilities remains less understood. AIM: Describe how health and care workers contribute to the prevention of emerging infectious diseases in long-term care facilities. DESIGN: A scoping review. METHODS: A systematic search of literature dating from 2002 to 2022 was conducted in the following databases: EMBASE, Medline (Ovid), Cochrane Library, CINAHL Plus with Full Text (EBSCOhost), Web of Science, and AgeLine. Studies were selected if they focused on health and care workers in long-term care facilities, offered a perspective on the prevention of emerging infectious diseases or infection prevention and control, and were original qualitative or quantitative studies in English. Data were extracted, cross-checked and analyzed by two researchers, and any difference in views regarding the appropriateness of literature would be resolved by consulting a third researcher. An inductive descriptive approach was applied for the analysis of results, and themes were established via consensus meetings. RESULTS: A total of fourteen studies from Asia, Europe, and the Americas were included. Three themes emerged from the review: "The roles of health and care workers evolve with the times", "The core competencies of health and care workers are essential for preventing emerging infectious diseases in long-term care facilities" and "The key to successful prevention of emerging infectious diseases in long-term care facilities is through a systematic, comprehensive effort that mobilize health and care workers at all levels". Health and care workers had to take on increasingly complex roles and rely on their core competencies to cope with epidemic changes, and facility resources, employee quality and management models were found to have significantly improved infection prevention and control outcomes. CONCLUSIONS: The roles of health and care workers are evolving, and effective infection prevention within long-term care facilities depends on their ability to perform core competencies with skill and confidence. Moreover, a systematic, comprehensive framework, for which this paper proposes three guidelines, is urgently needed to ensure consistent policy implementation within the facility as well as support and access to resources for health and care workers. CLINICAL RELEVANCE: Infection prevention efforts within long-term care facilities must take into account the evolving roles of health and care workers, with a focus on guaranteeing access to resources, training and support that will help them gain the core competencies necessary for juggling those roles. In addition, there is an urgent need for research instruments that will help assess those competencies and identify areas of improvement.

Effect of inhaled aromatherapy on sleep quality in critically ill patients: A systematic review and network meta-analysis.

AIM: This study aimed to compare the effect of inhaled aromatherapy using various essential oils on the sleep quality of critically ill patients. BACKGROUND: Inhalation of essential oils significantly promotes the physiological and psychological health of patients in intensive care units (ICUs). However, research identifying and ranking the effects of different essential oils on the sleep quality of critically ill patients is lacking. DESIGN: This study followed the PRISMA Extension Statement for Reporting of Systematic Reviews Incorporating Network Meta-Analyses of Health Care Interventions (PRISMA-NMA) guidelines. METHODS: A comprehensive search of five databases (Embase, MEDLINE, the Cochrane Library, CINAHL and PsycINFO) was conducted from their inception to March 15, 2023 (with an additional eligible study included dated August 14, 2023). Google Scholar was used as a supplementary method. Frequentist NMA was used to determine the effects of various essential oils. Certainty of evidence (CoE) was assessed using Confidence in Network Meta-Analysis (CINeMA). RESULTS: A total of 11 trials involving 690 critically ill patients were included in the analysis. The NMA of inhaled aromatherapy revealed that the combination of lavender, Matricaria recutita, and neroli essential oils (ratio 6:2:0.5) resulted in the most significant improvement in sleep quality compared to usual care, followed by Rosa damascene, peppermint, Citrus aurantium, pure sunflower oil and lavender oil alone. The overall CoE for the results was rated as low. CONCLUSIONS: The results of this study indicate that a combination of lavender, Matricaria recutita and neroli essential oils significantly positively affected sleep quality among critically ill patients. Despite the low quality of evidence, inhaled aromatherapy is non-invasive and easy to use. RELEVANCE TO CLINICAL PRACTICE: Inhaled aromatherapy can effectively improve sleep quality among critically ill patients. PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution applies to this work. STUDY REGISTRATION: The study protocol was registered to the PROSPERO International Prospective Register of Systematic Reviews (protocol number CRD42023433194).

Effectiveness of sound and darkness interventions for critically ill patients' sleep quality: A systematic review and component network meta-analysis.

BACKGROUND: Noise and lighting are prime factors of poor sleep quality in critically ill patients, which impair recovery and increase the risk of delirium or complications. AIM: To identify and rank the effectiveness of sound and darkness interventions on the sleep quality of critically ill patients. STUDY DESIGN: This systematic review and component network meta-analysis was based on the Preferred Reporting Items for Systematic Reviews incorporating the Network Meta-Analyses (PRISMA-NMA) Statement. The Embase, MEDLINE, Cochrane CENTRAL, CINAHL, Airiti Library, and Google Scholar databases were searched from inception to August 10, 2021, for randomized controlled trials (RCTs) on sound and darkness interventions targeting critically ill patients' sleep quality. We applied standard and component NMA to determine the effects of interventions. The certainty of evidence was evaluated using the Cochrane risk-of-bias tool (V.2.0) and the online Confidence in Network Meta-Analysis (CINeMA) application. RESULTS: Twenty-four RCTs with 1507 participants who used combined interventions constituting seven competing interventions were included in the standard NMA. The combination of earplugs, eye masks, and music; eye masks alone; earplugs combined with eye masks; and music alone had beneficial intervention effects. The combination of earplugs, eye masks, and music was the best intervention, and these components had no interaction effect. An eye mask had the best relative effect, followed by music, quiet time, and earplugs. CONCLUSIONS: This study provides clinical evidence of the effectiveness of using eye masks, music, and earplugs to improve sleep quality in critically ill patients. We also recommend future research using bedtime music, nocturnal eye masks, and quiet time, which had the best relative effects on sleep quality. RELEVANCE TO CLINICAL PRACTICE: This study provides recommendations for interventions that nurses can use to improve critically ill patients' sleep quality.

Efficacy of brief behavioural therapy for insomnia in older adults with chronic insomnia: a systematic review and meta-analysis from randomised trials.

BACKGROUND: chronic insomnia is a highly prevalent and persistent health concern among older adults, and it has significant adverse effects on cognitive function and physical health. OBJECTIVES: the study aimed to evaluate the efficacy of a brief 4-week behavioural therapy for insomnia (BBTi) on insomnia remission in older adults with chronic insomnia. DESIGN: a systematic review and meta-analysis were conducted. SUBJECTS: adults aged 60 years or older. METHODS: eight electronic databases were systematically searched through the end of March 2022. Studies followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Statement. RESULTS: four randomised controlled trials (190 subjects) were included. The mean age of the participants was 69.06 (65.10-71.65), and 29.9% (27.3-32.3%) were male. Older adults who received the BBTi showed a significant insomnia remission (standardised mean differences, -1.07; 95% confidence interval, -1.43 to -0.71; I2, 0%). Sleep parameters measured by actigraphy revealed that in older adults, the BBTi program significantly improved total sleep time, wake after sleep onset (WASO), sleep onset latency (SOL) and sleep efficacy (SE) compared to the controls. For the subjective sleep parameters measured the by sleep diary, older adults who received BBTi obtained a more effective improvement in WASO, SE and SOL. The overall risk of bias was mostly low or of some concern due to the difficulty of blinding participants and assessors. CONCLUSIONS: a 4-week BBTi program can be considered an effective and nonselective intervention for insomnia remission among older adults with chronic insomnia and thereby has the potential to ameliorate WASO, SE and SOL.

Effectiveness of outpatient geriatric evaluation and management intervention on survival and nursing home admission: a systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: The benefit of inpatient comprehensive geriatric assessment on patient survival and function has been demonstrated among frail older patients. However, the influence of outpatient geriatric evaluation and management (GEM) on clinical outcomes remains debated. This study aimed to update the research evidence detailing the effect of outpatient GEM on survival and nursing-home admission through a comparison with conventional care. METHODS: Cochrane Library, EMBASE, and MEDLINE databases were searched up to January 29th, 2022, to identify randomized controlled trials (RCTs) including older people over age 55 that compared outpatient GEM with conventional care on mortality (primary outcome) and nursing-home admission (secondary outcome) during a follow-up period of 12 to 36 months. RESULTS: Nineteen reports from 11 studies that recruited 7,993 participants (mean age 70-83) were included. Overall, outpatient GEM significantly reduced mortality (risk ratio (RR) = 0.87, 95% confidence interval (CI) = 0.77-0.99, I2 = 12%). For the subgroup analysis categorized by different follow-up periods, its prognostic benefit was only disclosed for 24-month mortality (RR = 0.68, 95% CI = 0.51-0.91, I2 = 0%), but not for 12- or 15 to 18-month mortality. Furthermore, outpatient GEM had significantly trivial effects on nursing-home admission during the follow-up period of 12 or 24 months (RR = 0.91, 95% CI = 0.74-1.12, I2 = 0%). CONCLUSIONS: Outpatient GEM led by a geriatrician with a multidisciplinary team improved overall survival, specifically during the 24-month follow-up period. This trivial effect was demonstrated in rates of nursing-home admission. Future research on outpatient GEM involving a larger cohort is warranted to corroborate our findings.

Effect of massage therapy on sleep quality in critically ill patients: A systematic review and meta-analysis.

AIM: The aim of the study was to compare the effects of massage interventions on sleep quality among patients in the adult critical care unit. BACKGROUND: Massage interventions have positive effects when applied to manage sleep quality in critical care units. However, research identifying the effect of massage intervention is limited. DESIGN: This study adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. METHODS: Five databases were searched from their inception to 15 April 2022 (the last search was conducted on 15 November 2022, but it yielded no additional eligible studies). The literature search was conducted using Embase, MEDLINE, the Cochrane Library, CINAHL, PsycINFO and additional sources such as Google Scholar. The Cochrane risk of bias tool for randomised trials (RoB 2.0) was used to assess the risk of bias. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) system assessed the certainty of evidence and recommendations. RESULTS: In total, ten randomised controlled trials comprising 569 participants were used in the systematic review, and eight trials were included in the meta-analysis. Subgroup analysis revealed significant effects of foot reflexology massage on subjective sleep quality. Massage therapy for a two-night duration in cardiac care unit patients exhibited a significant effect on subjective sleep quality. The overall GRADE certainty of evidence was low. CONCLUSION: Massage intervention, particularly foot reflexology massage, with a two-night duration showed improvement in subjective sleep quality among critically ill patients. Although evidence quality was low, the results suggest that massage interventions provide a non-invasive, low-cost and effective way to promote sleep quality in critically ill adult patients. RELEVANCE TO CLINICAL PRACTICE: Massage interventions can enable nurses to recommend and implement strategies promoting and improving sleep quality among critically ill patients. STUDY REGISTRATION: The review protocol was registered a priori and published online in the PROSPERO database of systematic reviews (www.crd.York.ac.uk/Prospero with the registration number # CRD42022332371). PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution if such details are not necessary or do not apply to your work and state why.

Effect of Vitamin B2 supplementation on migraine prophylaxis: a systematic review and meta-analysis.

OBJECTIVE: Migraine is a common disease worldwide and migraine prevention is primarily currently based on pharmaceuticals. The mechanism of Vitamin B2 may positively contribute to migraine. This systematic review and meta-analysis aimed to evaluate the impact of Vitamin B2 supplementation on the days, duration, frequency, and pain score of the migraine attack. METHODS: : The PRISMA guideline was used for the studying process. Five electronic databases, PubMed, Embase, Cochrane, CINAHL, and CEPS were searched from 1990 to March 2019. The search terms were Vitamin B2, migraine, and prophylactic. A meta-analysis was performed using Comprehensive Meta-Analysis (CMA) version. RESULTS: : Nine articles were included in systemic review and finally meta-analysis. Eight randomized controlled trials and one controlled clinical trial with 673 subjects were analyzed using meta-analysis. Vitamin B2 supplementation significantly decreased migraine days (p = .005, I2 = 89%), duration (p = .003, I2 = 0), frequency (p = .001, I2 = 65%), and pain score (p = .015, I2 = 84%). CONCLUSIONS: A pooled analysis of available randomized controlled clinical trials demonstrated that Vitamin B2 400 mg/day for three months supplementation had significant effect on days, duration, frequency, and pain score of migraine attacks.

The effects of exercise on chemotherapy-induced peripheral neuropathy symptoms in cancer patients: a systematic review and meta-analysis.

PURPOSE: To conduct a systematic review and meta-analysis of current studies to determine whether exercise affects chemotherapy-induced peripheral neuropathy (CIPN) symptoms in cancer patients. DESIGN: The Medline, Embase, Cochrane Library, CINAHL, PubMed, and National Central Library databases, and the reference lists of the included studies were surveyed. The Consolidated Standards of Reporting Trials (CONSORT) extension checklist for non-pharmacologic treatment was used to evaluate the literature. SETTING AND PARTICIPANTS: Exercise interventions offered in hospitals or at home. A total of 178 participants from 5 studies were assessed in the meta-analysis, with their mean age ranging from 48.56 to 71.82 years. METHODS: The randomized control trials were summarized in a systematic review. The effects of the exercise interventions were compiled for meta-analysis. A forest plot was constructed using a fixed effect model to obtain a pooled mean difference. RESULTS: The pooled results indicated that exercise interventions significantly improved the CIPN symptoms of the participants (mean difference: 0.5319; 95% confidence interval: 0.2295 to 0.8344; Z = 3.45; P = 0.0006). A combination of exercise protocols including a nerve gliding exercise intervention was found to have improved CIPN symptoms. In addition, a sensorimotor-based exercise intervention was found to have reduced CIPN-induced loss of postural stability. CONCLUSIONS AND IMPLICATIONS: The findings indicated that the effects of exercise could improve CIPN symptoms in cancer patients. Nevertheless, further investigations of different exercise protocols and intensity of intervention utilizing larger sample sizes and more specific outcome measures will further inform the best practices for cancer patients.

Effect of earplugs and eye masks on the sleep quality of intensive care unit patients: A systematic review and meta-analysis.

AIMS: To evaluate the effect of earplugs and eye masks on the sleep quality of patients in intensive care unit (ICU). DESIGN: Systematic review and meta-analysis. DATA SOURCES: Randomized controlled trial studies conducted before May 5, 2020 were searched for in Embase, MEDLINE, Cochrane Library, CINAHL and Index to Taiwan Periodical Literature System databases. REVIEW METHODS: Analyses in this study were according to the PRISMA statement. The heterogeneity of the data was investigated through sub-group analysis while a meta-analysis was performed using the Review Manager 5.3 software. RESULTS: A total of 797 patients from 13 studies were included in this study. Without considering alone or combined use of earplugs and eye masks, the meta-analysis supported that there was a significant effect on self-reported sleep quality. The overall standardized mean difference of the effect size was 1.44 (95% confidence interval [CI]: [0.80, 2.09]). Sub-group analysis indicated that the use of earplugs alone had no significant effect on sleep quality (effect size: 0.07, 95% [CI]: [-0.50, 0.64]). The use of eye masks alone had a significant effect on sleep quality (effect size: 1.56, 95% [CI]: [1.08, 2.05]). The use of both earplugs and eye masks proved to have the largest effect size on sleep quality (effect size: 2.08, 95% [CI]: [0.95, 3.21]). CONCLUSION: The combined use of earplugs and eye masks or the standalone use of eye masks is a non-invasive, economical and effective way to promote sleep quality in adult ICU patients. IMPACT: Clinical nurses could use this meta-analysis as it recommends that nurses provide adult ICU patients with either one or both earplugs and eye masks to improve the patients' sleep quality. STUDY REGISTRATION: The review protocol was registered a priori and published online in the PROSPERO database of systematic reviews (www.crd.York.ac.uk/Prospero with the registration number # CRD42021221185).

Zinc supplementation in patients with cirrhosis and hepatic encephalopathy: a systematic review and meta-analysis.

BACKGROUND: Low serum zinc level is associated with hepatic encephalopathy (HE), but the efficacy of zinc supplementation remains uncertain. This study aimed to investigate the effects of zinc supplementation on HE treatment in patients with cirrhosis. METHODS: We searched MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials (Cochrane CENTRAL) and Scopus from inception to December 2018; without publication date or language restrictions. Randomized controlled trials of zinc supplementation versus placebo or other treatment for the management of HE in adult patients with cirrhosis were selected. The primary outcome was the degree of HE as assessed by clinical signs or specialized psychometric tests. The secondary outcomes included serum ammonia levels, adverse events, or the length of hospital stay and costs. We carried out a meta-analysis with random effects model and summarized continuous outcomes using standardized mean differences (SMD) or mean differences (MD) with 95% confidence intervals (95% CI). The risk of bias was assessed using the Cochrane risk of bias tool, and the certainty of evidence for each outcome was evaluated with the Grading of Recommendations, Assessment, Development, and Evaluation approach. RESULTS: Four trials with 247 patients were included. In patients with cirrhosis who had mild HE (≤ grade II), the available evidence suggested that the combination treatment of zinc supplementation and lactulose over 3 to 6 months significantly improved performance in the number connection test (SMD: -0.97; 95% CI: - 1.75 to - 0.19; P = 0.01; moderate certainty), reported in three trials (n = 227). However, compared with lactulose therapy alone, additional zinc supplementation demonstrated no significant difference in the digit symbol test (SMD: 0.44; 95% CI: - 0.12 to 1.00; P = 0.12; very low certainty) or serum ammonia levels (MD: -10.86; 95% CI: - 25.73 to 4.01; P = 0.15; very low certainty), reported in two trials (n = 137). None of the included trials reported adverse events or effects on hospitalization. CONCLUSIONS: In conclusion, a combination of zinc supplementation and lactulose over 3 to 6 months may improve the number connection test in cirrhotic patients with low grade HE, compared with lactulose only.

Clinical efficacy and safety of faecal microbiota transplantation in the treatment of irritable bowel syndrome: a systematic review, meta-analysis and trial sequential analysis.

BACKGROUND: The aim of this study is to evaluate the efficacy and safety of faecal microbiota transplantation (FMT) for the treatment of irritable bowel syndrome (IBS). METHODS: We searched four databases for randomised controlled trials (RCTs) that compared FMT with a control intervention in patients with IBS. The revised Cochrane risk-of-bias (RoB) tool was chosen for appraisal. Meta-analysis with trial sequential analysis (TSA) was conducted. Grading of Recommendations Assessment Development and Evaluation (GRADE) methodology was used to assess the certainty of evidence (CoE). RESULTS: We included 12 RCTs with a total of 615 participants. Meta-analyses showed no significant difference between the FMT and control groups in terms of clinical responses (relative risk [RR] = 1.44, 95% confidence interval [CI] 0.88-2.33) and changes in IBS Severity Scoring System (IBS-SSS) scores (standardised mean difference [SMD] = - 0.31, 95% CI - 0.72 to 0.09) and IBS Quality of Life (IBS-QOL) scores (SMD = 0.30, 95% CI - 0.09 to 0.69). Subgroup analysis revealed that in studies with low RoB and using endoscopy, nasojejunal tube and rectal enema delivery, FMT led to a significant improvement in clinical responses and changes in IBS-SSS and IBS-QOL scores. TSA suggested that the current evidence is inconclusive and that the CoE is very low. CONCLUSION: This study suggests that patients with IBS may benefit from FMT especially when it is administered via endoscopy, nasojejunal tube or rectal enema. However, the certainty of evidence is very low. Further research is needed to confirm the efficacy and safety of FMT for IBS treatment.

Insights into optimal surgical fixation for posterior malleolar fractures.

Aims: The optimal management of posterior malleolar ankle fractures, a prevalent type of ankle trauma, is essential for improved prognosis. However, there remains a debate over the most effective surgical approach, particularly between screw and plate fixation methods. This study aims to investigate the differences in outcomes associated with these fixation techniques. Methods: We conducted a comprehensive review of clinical trials comparing anteroposterior (A-P) screws, posteroanterior (P-A) screws, and plate fixation. Two investigators validated the data sourced from multiple databases (MEDLINE, EMBASE, and Web of Science). Following PRISMA guidelines, we carried out a network meta-analysis (NMA) using visual analogue scale and American Orthopaedic Foot and Ankle Score (AOFAS) as primary outcomes. Secondary outcomes included range of motion limitations, radiological outcomes, and complication rates. Results: The NMA encompassed 13 studies, consisting of four randomized trials and eight retrospective ones. According to the surface under the cumulative ranking curve-based ranking, the A-P screw was ranked highest for improvements in AOFAS and exhibited lowest in infection and peroneal nerve injury incidence. The P-A screws, on the other hand, excelled in terms of VAS score improvements. Conversely, posterior buttress plate fixation showed the least incidence of osteoarthritis grade progression, postoperative articular step-off ≥ 2 mm, nonunions, and loss of ankle dorsiflexion ≥ 5°, though it underperformed in most other clinical outcomes. Conclusion: The NMA suggests that open plating is more likely to provide better radiological outcomes, while screw fixation may have a greater potential for superior functional and pain results. Nevertheless, clinicians should still consider the fragment size and fracture pattern, weighing the advantages of rigid biomechanical fixation against the possibility of soft-tissue damage, to optimize treatment results.

Determining the Optimal Treatment for Idiopathic Clubfoot: A Network Meta-Analysis of Randomized Controlled Trials.

BACKGROUND: Clubfoot, or congenital talipes equinovarus deformity, is a common anomaly affecting the foot in infants. However, clinical equipoise remains between different interventions, especially those based on the Ponseti method. The aim of this study was to examine the clinical outcomes of the various interventions for treating idiopathic clubfoot. METHODS: Searches of the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, Scopus, and CINAHL were conducted. Randomized controlled trials comparing different interventions, including the Ponseti method, accelerated Ponseti method, Ponseti method with botulinum toxin type A (Botox) injection, Ponseti method with early tibialis anterior tendon transfer (TATT), Kite method, and surgical treatment, were included. Network meta-analyses (NMAs) were conducted according to the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) reporting guidelines. The primary outcomes were the change in total Pirani score and maximal ankle dorsiflexion. Secondary outcomes were the number of casts, time in casts, and rates of tenotomy, total complications, relapse, adverse events, and additional required major surgery. RESULTS: Eleven randomized controlled trials involving 740 feet were included. According to the SUCRA (surface under the cumulative ranking curve)-based relative ranking, the Ponseti method was associated with the best outcomes in terms of Pirani score changes, maximal ankle dorsiflexion, number of casts, adverse events, and total complications, whereas the accelerated Ponseti method was associated with the best outcomes in terms of time in casts and tenotomy rate. Early TATT ranked best in terms of relapse rate. The Ponseti method with Botox injection was associated with the best outcomes in terms of the need for additional major surgery. CONCLUSIONS: The NMAs suggest that the Ponseti method is the optimal treatment overall, despite potential drawbacks such as longer time in casts and higher rates of tenotomy, relapse, and the need for additional surgery compared with other modified approaches. Therefore, clinicians should consider how treatments can be tailored individually. LEVEL OF EVIDENCE: Therapeutic Level I .

Beyond traditional therapies: a network meta-analysis on the treatment efficacy for chronic phantom limb pain.

BACKGROUND: Phantom limb pain (PLP) frequently affects individuals with limb amputations. When PLP evolves into its chronic phase, known as chronic PLP, traditional therapies often fall short in providing sufficient relief. The optimal intervention for chronic PLP remains unclear. OBJECTIVE: The objectives of this network meta-analysis (NMA) were to examine the efficacy of different treatments on pain intensity for patients with chronic PLP. EVIDENCE REVIEW: We searched Medline, EMBASE, Cochrane CENTRAL, Scopus, and CINAHL EBSCO, focusing on randomized controlled trials (RCTs) that evaluated interventions such as neuromodulation, neural block, pharmacological methods, and alternative treatments. An NMA was conducted based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The primary outcome was pain score improvement, and the secondary outcomes were adverse events. FINDINGS: The NMA, incorporating 12 RCTs, indicated that neuromodulation, specifically repetitive transcranial magnetic stimulation, provided the most substantial pain improvement when compared with placebo/sham groups (mean difference=-2.9 points, 95% CI=-4.62 to -1.18; quality of evidence (QoE): moderate). Pharmacological intervention using morphine was associated with a significant increase in adverse event rate (OR=6.04, 95% CI=2.26 to 16.12; QoE: low). CONCLUSIONS: The NMA suggests that neuromodulation using repetitive transcranial magnetic stimulation may be associated with significantly larger pain improvement for chronic PLP. However, the paucity of studies, varying patient characteristics across each trial, and absence of long-term results underscore the necessity for more comprehensive, large-scale RCTs.

Biomechanical comparison of different suture anchors used in rotator cuff repair surgery-all-suture anchors are equivalent to other suture anchors: a systematic review and network meta-analysis.

PURPOSE: Suture anchors are commonly used to repair rotator cuff tendons in arthroscopy surgery, and several anchor materials have been created to maximize pull-out strength and minimize iatrogenic damage. We hypothesized that all-suture anchors have biomechanical properties equivalent to those of conventional anchors. Our purpose is to compare the biomechanical properties of different anchors used for rotator cuff repair. METHODS: The Embase, PubMed, Cochrane, and Scopus databases were searched for biomechanical studies on various suture anchors. The search keywords included rotator cuff tears and suture anchors, and two authors conducted study a selection, risk of bias assessment, and data extraction. The failure load, stiffness, and displacement were calculated using the mean differences with 95% confidence intervals (CIs). Failure modes were estimated using summary odds ratios with 95% CIs. The surface under the cumulative ranking curve was used for the relative ranking probabilities. A sensitivity analysis was performed by excluding studies using synthetic bones. RESULTS: The polyetheretherketone (PEEK) (p < 0.001) and all-suture anchors (p < 0.001) had higher failure loads than the biocomposite anchors, whereas no significant difference was observed in stiffness among the anchors. The all-suture (p = 0.006) and biocomposite anchors (p < 0.001) had displacements higher than the metal anchors. The relative ranking of the included anchors in failure loads and displacement changed in sensitivity analysis. The meta-analysis did not find significant differences, but the relative ranking probabilities suggested that all-suture anchor had a higher rate of anchor pull-out and a lower rate of eyelet or suture breakage. In contrast, the metal anchors were associated with a higher number of eyelet breakage episodes. CONCLUSIONS: All-suture anchors showed significantly higher failure loads than the biocomposite anchors and similar cyclic displacements to the biocomposite and PEEK anchors. There were no significant differences in stiffness between all-suture and conventional suture anchors. The relative ranking of biomechanical properties changed in sensitivity analysis, suggesting the potential effect of bone marrow density. LEVEL OF EVIDENCE: Level IV.

Is implant choice associated with fixation strength for displaced radial neck fracture: a network meta-analysis of biomechanical studies.

The multitude of fixation options for radial neck fractures, such as pins, screws, biodegradable pins and screws, locking plates, and blade plates, has led to a lack of consensus on the optimal implant choice and associated biomechanical properties. This study aims to evaluate the biomechanical strength of various fixation constructs in axial, sagittal, and torsional loading directions. We included biomechanical studies comparing different interventions, such as cross/parallel screws, nonlocking plates with or without augmented screws, fixed angle devices (T or anatomic locking plates or blade plates), and cross pins. A systematic search of MEDLINE (Ovid), Embase, Scopus, and CINAHL EBSCO databases was conducted on September 26th, 2022. Data extraction was carried out by one author and verified by another. A network meta-analysis (NMA) was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. Primary outcomes encompassed axial, bending, and torsional stiffness, while the secondary outcome was bending load to failure. Effect sizes were calculated for continuous outcomes, and relative treatment ranking was measured using the surface under the cumulative ranking curve (SUCRA). Our analysis encompassed eight studies, incorporating 172 specimens. The findings indicated that fixed angle constructs, specifically the anatomic locking plate, demonstrated superior axial stiffness (mean difference [MD]: 23.59 N/mm; 95% CI 8.12-39.06) in comparison to the cross screw. Additionally, the blade plate construct excelled in bending stiffness (MD: 32.37 N/mm; 95% CI - 47.37 to 112.11) relative to the cross screw construct, while the cross-screw construct proved to be the most robust in terms of bending load failure. The parallel screw construct performed optimally in torsional stiffness (MD: 139.39 Nm/degree; 95% CI 0.79-277.98) when compared to the cross screw construct. Lastly, the nonlocking plate, locking T plate, and cross-pin constructs were found to be inferior in most respects to alternative interventions. The NMA indicated that fixed angle devices (blade plate and anatomic locking plate) and screw fixations may exhibit enhanced biomechanical strength in axial and bending directions, whereas cross screws demonstrated reduced torsional stability in comparison to parallel screws. It is imperative for clinicians to consider the application of these findings in constraining forces across various directions during early range of motion exercises, taking into account the distinct biomechanical properties of the respective implants.

Therapeutic effects of herbal-medicine combined therapy for COVID-19: A systematic review and meta-analysis of randomized controlled trials.

Background/Aim: Since 2019, the COVID-19 pandemic has been a devastating disease affecting global health to a great extent. Some countries have added on herbal medicines as a complementary treatment for combating COVID-19 due to the urgency of stopping the spread of this viral disease. However, whether these herbal medicines are effective is uncertain. This systematic review and meta-analysis aimed to evaluate the effects of herbal medicine combined therapy in the treatment of COVID-19. Methods: A literature search was performed following the PRISMA Statement and without language restrictions. Seven databases were searched from inception through December 2021. All selected studies were randomized clinical trials (RCTs). Comparing the effects of herbal medicine combined therapy with conventional western medicine, including improvement of clinical symptoms, chest CT images, viral conversion rate, C-reactive protein (CRP) and interleukin 6. Cochrane criteria were applied to examine the methodological quality of the enrolled trials; and meta-analysis software (RevMan 5.4.1) was used for data analysis. Results: In total, the data of 5,417 participants from 40 trials were included in this systematic review; and 28 trials were qualified for meta-analysis. The trials had medium-to-high quality based on GRADE system. Meta-analysis showed that combining herbal medicine vs conventional treatment in 1) coughing (1.43 95% CI:1.21, 1.71, p = 0.0001), 2) fever (1.09 95% CI:1.00, 1.19, p = 0.06), 3) fatigue (1.21 95% CI:1.10, 1.33, p = 0.0001); 4) CT images (1.26 95% CI:1.19, 1.34, P ≤ 0.00001), 5) viral conversion rates (1.22 95% CI:1.06, 1.40, p = 0.005) and 6) viral conversion times (-3.72 95% CI: -6.05, -1.40, p = 0.002), 7) IL6 change (1.97 95% CI: -0.72, 4.66, p = 0.15) and 8) CRP change (-7.92 95% CI: -11.30, -4.53, P ≤ 0.00001). Conclusion: Herbal medicine combined therapy significantly reduces COVID-19 clinical symptoms, improving CT images and viral conversion rates. Reported adverse events are mild. However, for certain biases in the included studies, and the need for further study on effective components of herbal medicine. Further large trials with better randomized design are warranted to definite a more definite role of herbal medicine.

Comparative anatomical outcomes of high-flow vs. low-flow phacoemulsification cataract surgery: A systematic review and meta-analysis.

Background: Phacoemulsification is an effective and widely performed technique in cataract surgery, but the comparative anatomical outcomes, including endothelial cell loss (ECL), central corneal thickness (CCT), and central macular thickness (CMT), between high-flow and low-flow phacoemulsification cataract surgery remain unclear. Methods: This study followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Statement. Random-effects models were applied to measure pooled mean differences (MD) with 95% confidence intervals (CI) of anatomical outcomes between high-flow and low-flow phacoemulsification cataract surgery. We judged overall certainty of evidence (CoE) based on Grading of Recommendations Assessment, Development and Evaluation (GRADE) criteria. Results: We included six randomized controlled trials (RCTs) totaling 477 participants. The meta-analysis showed similar changes associated with these two surgery types in both ECL at postoperative days 2-14 (MD: -1.63%; 95% CI: -3.73 to 0.47%; CoE: very low), days 15-42 (MD: -0.65%; 95% CI -2.96 to 1.65%; CoE: very low) and day 43 to month 18 (MD: -0.35%; 95% CI: -1.48 to 0.78%; CoE: very low), and CCT at postoperative day 1 (MD: -16.37 µm; 95% CI: -56.91 to 24.17 µm; CoE: very low), days 2-14 (MD: -10.92 µm; 95% CI: -30.00 to 8.16 µm; CoE: very low) and days 15-42 (MD: -2.76 µm; 95% CI: -5.75 to 0.24 µm; CoE: low). By contrast, low-flow phacoemulsification showed less increase in CMT at postoperative days 15-42 (MD, -4.58 µm; 95% CI: -6.3 to -2.86 µm; CoE: low). Conclusions: We found similar anatomical outcomes, except in CMT, for both high-flow and low-flow phacoemulsification cataract surgery. Future head-to-head RCTs on visual outcomes should confirm our findings. Systematic review registration: PROSPERO, identifier: CRD42022297036.

Intravenous Infusion of Lidocaine for Bowel Function Recovery After Major Colorectal Surgery: A Critical Appraisal Through Updated Meta-Analysis, Trial Sequential Analysis, Certainty of Evidence, and Meta-Regression.

BACKGROUND: Intravenous infusion of lidocaine (IVF-Lido) during the perioperative period is an option to accelerate bowel function recovery after major colorectal surgery. However, previous meta-analyses have shown inconsistent conclusions. Recent randomized controlled trials (RCTs) have been reported after the publication of a previous meta-analysis. AIM: We conducted an updated and comprehensive meta-analysis to determine the effects of IVF-Lido on time to first flatus and defecation after major colorectal surgery. METHODS: We performed a systematic review according to the Preferred Reporting Items for the Systematic Reviews and Meta-Analysis Protocols 2020 guideline. Only RCTs were included. The revised Cochrane risk-of-bias tool was chosen for appraisal. Meta-analysis with meta-regression and trial sequential analysis was carried out. The Doi plot was presented to evaluate publication bias. The Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) methodology was executed to evaluate the certainty of evidence (CoE). RESULTS: Thirteen RCTs with 696 participants were enrolled. IVF-Lido significantly decreased the time to first flatus [mean difference (MD) = -6.03 h; 95% confidence interval (CI): (-8.80, -3.26)] and first defecation [MD = -10.49 h; 95% CI: (-15.58, -5.41)]. Trial sequential analysis yielded identical results and ampleness of required information sizes. No obviousness in publication bias was detected, and the CoE in GRADE was low in both outcomes. Meta-regression showed that a significantly shorter time to the first defecation was associated with studies with more improvement in pain control in comparison of two groups and better-improved analgesia in the control group. CONCLUSIONS: We discretionarily suggest the use of IVF-Lido on postoperative bowel function recovery following major colorectal surgery. Beyond the analgesic effects, IVF-Lido might have additional benefits when postoperative pain relief has already been achieved. Considering the high heterogeneity in this updated meta-analysis, more RCTs are needed. SYSTEMATIC REVIEW REGISTRATION: https://inplasy.com/inplasy-2020-7-0023/, INPLASY [202070023].
