Effectiveness of Botulinum Toxin Treatment for Upper Limb Spasticity Poststroke Over Different ICF Domains: A Systematic Review and Meta-Analysis

ObjectiveTo provide a comprehensive overview of reported effects and scientific robustness of botulinum toxin (BoNT) treatment regarding the main clinical goals related to poststroke upper limb spasticity, using the International Classification of Functioning, Disability and Health.Data SourcesEmbase, PubMed, Wiley/Cochrane Library, and Ebsco/CINAHL were searched from inception up to May 16, 2018.Study SelectionWe included randomized controlled trials comparing upper limb BoNT injections with a control intervention in patients with a history of stroke. A total of 1212 unique records were screened by 2 independent reviewers. Forty trials were identified, including 2718 patients with history of stroke.Data ExtractionOutcome data were pooled according to assessment timing (ie, 4-8wk and 12wk after injection), and categorized into 6 main clinical goals (ie, spasticity-related pain, involuntary movements, passive joint motion, care ability, arm and hand use, and standing and walking performance). Sensitivity analyses were performed for the influence of study and intervention characteristics, involvement of pharmaceutical industry, and publication bias.Data SynthesisRobust evidence is shown for the effectiveness of BoNT in reducing resistance to passive movement, as measured with the (Modified) Ashworth Score, and improving self-care ability for the affected hand and arm after intervention (P<.005) and at follow-up (P<.005). In addition, robust evidence is shown for the absence of effect on arm-hand capacity at follow-up. BoNT was found to significantly reduce involuntary movements, spasticity-related pain, and caregiver burden, and improve passive range of motion, while no evidence was found for arm and hand use after intervention.ConclusionsIn view of the robustness of current evidence, no further trials are needed to investigate BoNT for its favorable effects on resistance to passive movement of the spastic wrist and fingers, and on self-care. No trials are needed to further confirm the lack of effects of BoNT on arm-hand capacity, whereas additional trials are needed to establish the suggested favorable effects of BoNT on other body functions, which may result in clinically meaningful outcomes at activity and participation levels.     

Comparative Effectiveness of Orthoses for Thumb Osteoarthritis: A Systematic Review and Network Meta-analysis

ObjectiveTo evaluate the best option among orthoses for carpometacarpal (CMC) osteoarthritis (OA) of the thumb, using a network meta-analysis.Data SourcesMedline, Embase, Cochrane, and ClinicalTrials.gov registry databases were used. PubMed, Embase, Cochrane Controlled Trials Register, Cochrane, and other databases were used without language restrictions.Study SelectionWe searched randomized controlled trials (RCTs) on adults with OA of the thumb by studying any orthosis from the beginning to March 10, 2020.Data ExtractionData were extracted and checked for accuracy and completeness by pairs of reviewers. Outcomes were pain and function. Comparative treatment effects were analyzed by random-effects model for direct pairwise comparisons and Bayesian network meta-analyses to integrate direct and indirect evidence.Data SynthesisEleven RCTs involving 619 patients were included. We evaluated 5 groups, for 4 different orthoses: short thermoplastic CMC splint (rigid CMC) (n=5), long thermoplastic carpometacarpal-metacarpophalangeal splint (rigid CMC-MCP) (n=7), short neoprene CMC splint (soft CMC) (n=1), long neoprene CMC-MCP splint (soft CMC-MCP) (n=5), and one as a control group (n=5). Our results show that all splints were superior to placebo to reduce pain intensity and the top-ranked intervention was the rigid CMC-MCP (surface under the cumulative ranking curve analysis [SUCRA], score: 65.4). In function evaluation, we report a 71.6 SUCRA for rigid CMC.ConclusionsAlthough the current evidence is unclear on the use of the splint in OA of the thumb, it is not known which orthosis is more effective and whether the orthosis is more effective than other interventions. The network meta-analysis shows that a long thermoplastic splint it is the best choice for pain relief and the short thermoplastic CMC splint is the best treatment to increase function. These results may suggest initial treatment with a long rigid orthosis and then a short rigid orthosis.     

Robotic-Assisted Shoulder Rehabilitation Therapy Effectively Improved Poststroke Hemiplegic Shoulder Pain: A Randomized Controlled Trial

ObjectiveThe purpose of this study was to investigate the therapeutic effects of a newly developed shoulder robot on poststroke hemiplegic shoulder pain.DesignProspective, single-blind randomized controlled trial.SettingInpatient department of a tertiary university hospital.ParticipantsHemiplegic shoulder pain patients (N=38) were consecutively recruited and randomly assigned to an intervention or control group.InterventionsA newly developed robot was designed to perform joint mobilization and stretching exercises with patients lying in the supine position. Conventional physical therapy directed at both improving upper extremity mechanics and reducing neurologic injury was performed twice per day in both groups. In the intervention group, additional robotic-assisted shoulder rehabilitation therapy was administered for 30 minutes per day, 5 times per week for 4 weeks.Main Outcome MeasuresThe visual analog scale was the primary outcome, and the pain-free passive range of motion of the shoulder joint, the Korean version of the Shoulder Disability Questionnaire, and ultrasonographic grades were the secondary outcomes. The outcomes were evaluated at baseline (T0), postintervention (T1), and a 4-week follow-up (T2).ResultsSignificant time and group interaction effects were found on the visual analog scale, in the abduction passive range of motion, and on the Shoulder Disability Questionnaire (F_2,33=16.384, P=.002; F_2,33=10.609, P=.012; F_2,33=32.650, P=.008, respectively). Significantly higher improvements in these outcome measures were observed in the intervention group than in the control group at T1 after post hoc analysis (P<0.05, all). These improvements were sustained at T2 when the intervention group was compared with the control group (P<.05, all).ConclusionsA prototype shoulder rehabilitation robot as an adjuvant therapy improves hemiplegic shoulder pain and self-reported shoulder-related disability.     

The Effectiveness and Safety of Platelet-Rich Plasma for Chronic Wounds: A Systematic Review and Meta-analysis

ObjectiveTo evaluate the effectiveness and adverse events of autologous platelet-rich plasma (PRP) in individuals with lower-extremity diabetic ulcers, lower-extremity venous ulcers, and pressure ulcers.Patients and MethodsWe searched multiple databases from database inception to June 11, 2020, for randomized controlled trials and observational studies that compared PRP to any other wound care without PRP in adults with lower-extremity diabetic ulcers, lower-extremity venous ulcers, and pressure ulcers.ResultsWe included 20 randomized controlled trials and five observational studies. Compared with management without PRP, PRP therapy significantly increased complete wound closure in lower-extremity diabetic ulcers (relative risk, 1.20; 95% CI, 1.09 to 1.32, moderate strength of evidence [SOE]), shortened time to complete wound closure, and reduced wound area and depth (low SOE). No significant changes were found in terms of wound infection, amputation, wound recurrence, or hospitalization. In patients with lower-extremity venous ulcers or pressure ulcers, the SOE was insufficient to estimate an effect on critical outcomes, such as complete wound closure or time to complete wound closure. There was no statistically significant difference in adverse events.ConclusionAutologous PRP may increase complete wound closure, shorten healing time, and reduce wound size in individuals with lower-extremity diabetic ulcers. The evidence is insufficient to estimate an effect on wound healing in individuals with lower-extremity venous ulcers or pressure ulcers.Trial RegistrationPROSPERO Identifier: CRD42020172817     

Whole Body Vibration Exercise for Chronic Musculoskeletal Pain: A Systematic Review and Meta-analysis of Randomized Controlled Trials

ObjectiveThis study systematically reviews previous work on the effects of whole body vibration exercise (WBVE) on pain associated with chronic musculoskeletal disorders.Data SourcesSeven electronic databases (PubMed, Embase, CINAHL, Web of Science, Cochrane, Physiotherapy Evidence Database [PEDro], and the China National Knowledge Infrastructure) were searched for articles published between January 1980 and September 2018.Study SelectionRandomized controlled trials involving adults with chronic low back pain (CLBP), osteoarthritis (OA), or fibromyalgia were included. Participants in the WBVE intervention group were compared with those in the nontreatment and non-WBVE control groups.Data ExtractionData were independently extracted using a standardized form. Methodological quality was assessed using PEDro.Data SynthesisSuitable data from 16 studies were pooled for meta-analysis. A random effects model was used to calculate between-groups mean differences at 95% confidence interval (CI). The data were analyzed depending on the duration of the follow-up, common disorders, and different control interventions.ResultsAlleviation of pain was observed at medium term (standardized mean difference [SMD], -0.67; 95% CI, -1.14 to -0.21; I², 80%) and long term (SMD, -0.31; 95% CI, -0.59 to -0.02; I², 0%). Pain was alleviated in osteoarthritis (OA) (SMD, -0.37; 95% CI, -0.64 to -0.10; P<.05; I², 22%) and CLBP (SMD, -0.44; 95% CI, -0.75 to -0.13; P<.05; I², 12%). Long-term WBVE could relieve chronic musculoskeletal pain conditions of OA (SMD, -0.46; 95% CI, -0.80 to -0.13; P<.05; I², 0%). WBVE improved chronic musculoskeletal pain compared with the treatment “X” control (SMD, -0.37; 95% CI, -0.61 to -0.12; P<.05; I², 26%), traditional treatment control (SMD, -1.02; 95% CI, -2.44 to 0.4; P>.05; I², 94%) and no treatment control (SMD, -1; 95% CI, -1.76 to -0.24; P<.05; I², 75%).ConclusionsEvidence suggests positive effects of WBVE on chronic musculoskeletal pain, and long durations of WBVE could be especially beneficial. However, WBVE does not significantly relieve chronic musculoskeletal pain compared with the traditional treatment. Further work is required to identify which parameters of WBVE are ideal for patients with chronic musculoskeletal pain.     

Effectiveness of Physical Therapy Interventions in Reducing Fear of Falling Among Individuals With Neurologic Diseases: A Systematic Review and Meta-analysis

ObjectiveTo summarize the effectiveness of physical therapy interventions to reduce fear of falling (FOF) among individuals living with neurologic diseases.Data SourcesPubMed, Physiotherapy Evidence Database, Scopus, Web of Science, PsycINFO, Cumulative Index to Nursing and Allied Health, and SportDiscuss were searched from inception until December 2019.Study SelectionClinical trials with either the primary or secondary aim to reduce FOF among adults with neurologic diseases were selected.Data ExtractionPotential articles were screened for eligibility, and data were extracted by 2 independent researchers. Risk of bias was assessed by the Cochrane Risk of Bias tool for randomized controlled trials and the National Institutes of Health Quality Assessment Tool for pre-post studies. A meta-analysis was performed among trials presenting with similar clinical characteristics. The Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) was used to rate the overall quality of evidence.ResultsSixty-one trials with 3954 participants were included in the review and 53 trials with 3524 participants in the meta-analysis. The included studies presented, in general, with a low to high risk of bias. A combination of gait and balance training was significantly more effective compared with gait training alone in reducing FOF among individuals with Parkinson disease (PD) (mean difference [MD]=11.80; 95% CI, 8.22-15.38; P<.001). Home-based exercise and leisure exercise demonstrated significant improvement in reducing FOF over usual care in multiple sclerosis (MS) (MD=15.27; 95% CI, 6.15-24.38; P=.001). No statistically significant between-groups differences were reported among individuals with stroke and spinal cord injury. The overall quality of evidence presented in this review ranges from very low to moderate according to the assessment with the GRADE approach.ConclusionsGait with lower limb training combined with balance training is effective in reducing FOF in individuals with PD. Also, home-based or leisure exercise is effective among individuals with MS. However, because of several limitations of the included studies, further research is needed to examine the effectiveness of FOF intervention among individuals with neurologic diseases.     

Janus Kinase Inhibitors and Risk of Venous Thromboembolism: A Systematic Review and Meta-analysis

ObjectiveTo assess the risk of venous thromboembolism (VTE) in patients treated with Janus kinase (JAK) inhibitors in clinical trials.Patients and MethodsWe performed a literature search of Ovid MEDLINE and ePub Ahead of Print, In-Process & Other Non-Indexed Citations, and Daily; Ovid EMBASE; Ovid Cochrane Central Register of Controlled Trials; Ovid Cochrane Database of Systematic Reviews; and Scopus, from inception to December 4, 2019, for randomized, placebo-controlled trials with JAK inhibitors as an intervention and reported adverse events. Odds ratio with 95% CI was calculated to estimate the VTE risk using a random effects model. Two independent reviewers screened and extracted data. The GRADE (Grading of Recommendations Assessment, Development and Evaluation) approach was used to assess certainty in estimated VTE risk.ResultsWe included 29 trials (13,910 patients). No statistically significant association was found between use of JAK inhibitors and risk of VTE (odds ratio, 0.91; 95% CI, 0.57 to 1.47; P=.70; I²=0; low certainty because of serious imprecision). Results using Bayesian analysis were consistent with those of the primary analysis. Results of stratified and meta-regression analyses suggested no interaction by dose of drug, indication for treatment, or length of follow-up.ConclusionWe found insufficient evidence to support an increased risk of JAK inhibitor–associated VTE based on currently available data.     

Edaravone for Acute Ischemic Stroke: A Systematic Review and Meta-analysis

PurposeThe management of acute stroke is challenging. The aim of this meta-analysis was to determine the efficacy and tolerability of edaravone, with or without thrombolytic therapy, in the treatment of patients with acute ischemic stroke.MethodsThe PubMed, EMBASE, and Cochrane databases were searched for randomized controlled trials (RCTs) and cohort studies. Mean differences (MD), risk ratios (RR), 95% confidence interval (CI), and heterogeneity were calculated.FindingsTotals of nine RCTs and four cohort studies were included, for a total of 2102 patients. In patients with acute ischemic stroke, edaravone monotherapy was associated with significantly improved Barthel Index of functioning in activities for daily living (MD, 23.95; 95% CI, 18.48 to 29.41; P < 0.001) and neurologic deficit, (as measured using the National Institutes of Health Stroke Scale score) (MD = –3.49; 95% CI, –5.76 to 1.22; P = 0.003), on short-term follow-up. However, edaravone was not associated with an improved rate of death or disability (RR = 0.75; 95% CI, 0.45 to 1.23; P = 0.25) on long-term follow-up.When plus to thrombolytic therapy, edaravone was associated with significant improvements in recanalization rate (RR = 1.71; 95% CI, 1.05 to 2.77; P = 0.03) and neurologic deficit (MD = 3.97; 95% CI, 5.14 to 2.79; P < 0.001), without an increase in the prevalence of bleeding events (RR = 1.11; 95% CI, 0.76 to 1.62; P = 0.59). However, edaravone did not have a significant effect on death or disability (RR = 0.85; 95% CI, 0.69 to 1.04; P = 0.12).ImplicationsBased on the findings from the present meta-analysis, edaravone was an effective and well-tolerated neuroprotective agent in these patients with ischemic stroke. With the use of edaravone, activities of daily living and neurologic deficits, along with recanalization rates, were improved on short-term follow-up, but the long-term effects still need confirmation in larger-scale clinical trials.     

Direct Oral Anticoagulants Compared With Dalteparin for Treatment of Cancer-Associated Thrombosis: A Living,Interactive Systematic Review and Network Meta-analysis

ObjectiveTo maintain living, interactive evidence (LIvE) on the benefits and harms of different treatment options in adults with cancer-associated thrombosis (CAT).MethodsWe have used a novel LIvE synthesis framework to maintain this living, interactive systematic review since September 19, 2018. Randomized controlled trials evaluating the efficacy and safety of direct oral anticoagulants (DOACs) compared with low-molecular-weight heparin for CAT are included in this analysis. Details of LIvE synthesis framework are available at the website https://cat.network-meta-analysis.com.ResultsThe results are constantly updated as new information becomes available (https://cat.network-meta-analysis.com/CAT.html). The living, interactive systematic review currently includes 4 randomized controlled trials (N=2894). Direct comparisons show that DOACs significantly decrease recurrent venous thromboembolism (VTE) events compared with dalteparin (odds ratio [OR], 0.59; 95% CI, 0.41 to 0.86; I², 25%) without significantly increasing major bleeding (OR, 1.34; 95% CI, 0.83 to 2.18; I², 28%). Mixed treatment comparisons show that apixaban (OR, 0.41; 95% credible interval [CrI], 0.16 to 0.95) and rivaroxaban (OR, 0.58; 95% CrI, 0.37 to 0.90) significantly decrease VTE recurrent events compared with dalteparin. Edoxaban significantly increases major bleeding compared with dalteparin (OR, 1.73; 95% CrI, 1.04 to 3.16), and rivaroxaban significantly increases clinically relevant nonmajor bleeding compared with dalteparin and other DOACs. There are no significant differences between DOACs in terms of VTE recurrences and major bleeding.ConclusionDOACs should be considered a standard of care for the treatment of CAT except in patients with a high risk of bleeding. Current evidence favors the use of apixaban for the treatment of CAT among other DOACs.RegistrationOpen Science Framework (https://osf.io/dth86).     

Effect of the Renin-Angiotensin System Inhibitors on Inflammatory Markers: A Systematic Review and Meta-analysis of Randomized Controlled Trials

ObjectiveTo synthesize more conclusive evidence on the anti-inflammatory effects of angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs).MethodsPubMed, Scopus, and Embase were searched from inception until March 1, 2021. We included randomized controlled trials (RCTs) that assessed the effect of ACEIs or ARBs, compared with placebo, on any of the following markers: C-reactive protein (CRP), interleukin 6 (IL-6), or tumor necrosis factor α (TNF-α). Mean changes in the levels of these markers were pooled as a weighted mean difference (WMD) with a 95% CI.ResultsThirty-two RCTs (n=3489 patients) were included in the final analysis. Overall pooled analysis suggested that ACEIs significantly reduced plasma levels of CRP (WMD, ?0.54 [95% CI, ?0.88 to ?0.21]; P=.002; I²=96%), IL-6 (WMD, ?0.84 [95% CI, ?1.03 to ?0.64]; P<.001; I²=0%), and TNF-α (WMD, ?12.75 [95% CI, ?17.20 to ?8.29]; P<.001; I²=99%). Moreover, ARBs showed a significant reduction only in IL-6 (WMD, ?1.34 [95% CI, ?2.65 to ?0.04]; P=.04; I²=85%) and did not significantly affect CRP (P=.15) or TNF-α (P=.97) levels. The lowering effect of ACEIs on CRP levels remained significant with enalapril (P=.006) and perindopril (P=.01) as well as with a treatment duration of less than 24 weeks (WMD, -0.67 [95% CI, ?1.07 to -0.27]; P=.001; I²=94%) and in patients with coronary artery disease (WMD, ?0.75 [95% CI, ?1.17 to ?0.33]; P<.001; I²=96%).ConclusionBased on this meta-analysis, ACEIs showed a beneficial lowering effect on CRP, IL-6, and TNF-α, whereas ARBs were effective as a class in reduction of IL-6 only.     

Ballistic Resistance Training: Feasibility,Safety, and Effectiveness for Improving Mobility in Adults With Neurologic Conditions: A Systematic Review

ObjectivesTo determine whether ballistic resistance training is feasible, safe, and effective in improving muscle strength, power generation, and mobility in adults with neurologic conditions.Data SourcesNine electronic databases were searched from inception to March 2019 in addition to the reference lists of included articles.Study SelectionArticles were independently screened by 2 authors and were included if they were full-text; English-language articles published in a peer-reviewed journal; investigated ballistic resistance training for adults with a neurologic condition; and reported on feasibility, safety, strength, power, or mobility.Data ExtractionTwo authors independently extracted data. Study quality was assessed using the McMaster critical review form and the Physiotherapy Evidence Database scale.Data SynthesisThe search identified 1540 articles, with 13 articles describing 9 studies meeting the criteria for inclusion. Five studies were randomized controlled trials and 4 were cohort studies. Ballistic resistance training was feasible and safe with only 1 intervention-related adverse event reported. Findings indicated improvements in strength for hip abduction, leg press, knee flexion, and ankle dorsiflexion, but not for hip flexion, hip extension, knee extension, or ankle plantarflexion. Muscle power generation improved for hip flexion, hip abduction, leg press, knee extension, and knee flexion, but not for ankle plantarflexion. Treatment effect was positive for self-selected walking speed, with a standardized mean difference (SMD) of 0.69 (95% confidence interval [CI], 0.01-1.38) from 3 studies. However, fastest comfortable walking speed results were inconclusive with a SMD from 4 studies of 0.45 (95% CI, –0.01 to 0.91).ConclusionsBallistic training is safe and feasible for people with a neurologic condition. The effects on muscle strength, power generation, and mobility were found to be positive but not conclusive.     

Efficacy and Safety of High-Frequency Repetitive Transcranial Magnetic Stimulation for Poststroke Depression: A Systematic Review and Meta-analysis

ObjectiveTo summarize and systematically review the efficacy and safety of high-frequency repetitive transcranial magnetic stimulation (HF-rTMS) for depression in patients with stroke.Data SourcesSix databases (Wanfang, the China National Knowledge Infrastructure, PubMed, Embase, Cochrane Library, and Web of Science) were searched from inception until November 15, 2018.Study SelectionSeventeen randomized controlled trials were included for meta-analysis.Data ExtractionTwo independent reviewers selected potentially relevant studies based on the inclusion criteria, extracted data, and evaluated the methodological quality of the eligible trials using the Physiotherapy Evidence Database.Data SynthesisWe calculated the combined effect size (standardized mean difference [SMD] and odds ratio [OR]) for the corresponding effects models. Physiotherapy Evidence Database scores ranged from 7 to 8 points (mean=7.35). The study results indicated that HF-rTMS had significantly positive effects on depression in patients with stroke. The effect sizes of the SMD ranged from small to large (SMD, -1.01; 95% confidence interval [CI], -1.36 to -0.66; P<.001; I², 85%; n=1053), and the effect sizes of the OR were large (response rates, 58.43% vs 33.59%; OR, 3.31; 95% CI, 2.25-4.88; P<.001; I², 0%; n=529; remission rates, 26.59% vs 12.60%; OR, 2.72; 95% CI, 1.69-4.38; P<.001; I², 0%; n=529). In terms of treatment side effects, the HF-rTMS group was more prone to headache than the control group (OR, 3.53; 95% CI, 1.85-8.55; P<.001; I², 0%; n=496).ConclusionsHF-rTMS is an effective intervention for poststroke depression, although treatment safety should be further verified via large sample multicenter trials.     

Does Intradialytic Exercise Improve Removal of Solutes by Hemodialysis? A Systematic Review and Meta-analysis

ObjectiveTo describe a systematic review and meta-analysis to identify if intradialytic exercise improves the removal of solutes and the hemodialysis adequacy.Data SourcesA systematic review and meta-analysis of randomized controlled trials (RCTs) were performed. The sources were MEDLINE (via PubMed), Web of Science, LILACS, and SciELO, from inception until July 2018.Study SelectionClinical trials including patients on chronic hemodialysis submitted to the intervention of aerobic intradialytic exercise.Data ExtractionEvaluating as outcomes the removal of solutes (creatinine, phosphate, potassium) and/or adequacy parameters (Kt/V-urea).Data SynthesisThe systematic review included 23 studies (7 evaluating the effect of 1 exercise session and 16 evaluating the effect of training, lasting from 6 to 25 weeks). Eleven RCT were included in the meta-analyses. It was observed that the aerobic intradialytic exercise increased the Kt/V-urea (0.15; 95% confidence interval [95% CI], 0.08-0.21) and decreased creatinine (–1.82 mg/dL; 95% CI, –2.50 to –1.13), despite the high heterogeneity of the analysis. No differences were found in phosphorus and potassium removal.ConclusionThe aerobic intradialytic exercise may be suggested to improve the Kt/V-urea and the creatinine removal during the dialysis.     

Newer P2Y12 Inhibitors vs Clopidogrel in Acute Myocardial Infarction With Cardiac Arrest or Cardiogenic Shock: A Systematic Review and Meta-analysis

ObjectiveTo evaluate the outcomes, safety, and efficacy of dual antiplatelet therapy (DAPT) with newer P2Y₁₂ inhibitors compared with clopidogrel in patients with acute myocardial infarction (AMI) complicated by cardiac arrest (CA) or cardiogenic shock (CS).Patients and MethodsMEDLINE, EMBASE, and the Cochrane Library were queried systematically from inception to January 2021 for comparative studies of adults (≥18 years) with AMI-CA/CS receiving DAPT with newer P2Y₁₂ inhibitors as opposed to clopidogrel. We compared outcomes (30-day or in-hospital and 1-year all-cause mortality, major bleeding, and definite stent thrombosis) of newer P2Y₁₂ inhibitors and clopidogrel in patients with AMI-CA/CS.ResultsEight studies (1 randomized trial and 7 cohort studies) comprising 1100 patients (695 [63.2%] receiving clopidogrel and 405 [36.8%] receiving ticagrelor or prasugrel) were included. The population was mostly male (68.5%-86.7%). Risk of bias was low for these studies, with between-study heterogeneity and subgroup differences not statistically significant. Compared with the clopidogrel cohort, the newer P2Y₁₂ cohort had lower rates of early mortality (odds ratio [OR], 0.60; 95% CI, 0.45 to 0.81; P=.001) (7 studies) and 1-year mortality (OR, 0.51; 95% CI, 0.36 to 0.71; P<.001) (3 studies). We did not find a significant difference in major bleeding (OR, 1.21; 95% CI, 0.71 to 2.06; P=.48) (6 studies) or definite stent thrombosis (OR, 2.01; 95% CI, 0.63 to 6.45; P=.24) (7 studies).ConclusionIn patients with AMI-CA/CS receiving DAPT, compared with clopidogrel, newer P2Y₁₂ inhibitors were associated with lower rates of early and 1-year mortality. Data on major bleeding and stent thrombosis were inconclusive.     

Continuous Passive Motion After Total Knee Arthroplasty: A Systematic Review and Meta-analysis of Associated Effects on Clinical Outcomes

ObjectiveTo evaluate the efficacy of continuous passive motion (CPM) after total knee arthroplasty (TKA) and whether the use of CPM is related to improved clinical and functional outcomes.Data SourcesA systematic MEDLINE search via Web of Science, Cochrane Library, and PubMed databases was conducted.Study SelectionEnglish-language articles published between January 2000 and May 2018 reporting the related clinical outcomes of CPM after TKA were included. A total of 3334 titles and abstracts were preliminarily reviewed, of which 16 studies were included according to the eligibility criteria.Data ExtractionTwo different reviewers were selected to perform the study extraction, independent of each other. If there were any disagreements regarding the final list of studies, the third reviewer reviewed the list as an arbitrator for completeness.Data SynthesisA total of 16 trials with 1224 patients were included. The pooled results revealed that use of CPM did not show a statistically significant improvement of postoperative knee range of motion (ROM) except for middle-term passive knee extension and long-term active knee flexion ROM. Also, CPM therapy did not show a significant positive effect on the functional outcomes. No significant reduction in length of stay (LOS) and incidence of adverse events (AEs) was identified.ConclusionAmong patients undergoing TKA, neither the ROM nor the functional outcomes could be improved by CPM therapy. Moreover, the risk of AEs and LOS could not be reduced by application of CPM. The current available evidence suggested that this intervention was insufficient to be used routinely in clinical practice.     

The Effect of Convalescent Plasma Therapy on Mortality Among Patients With COVID-19: Systematic Review and Meta-analysis

To determine the effect of COVID-19 convalescent plasma on mortality, we aggregated patient outcome data from 10 randomized clinical trials, 20 matched control studies, 2 dose-response studies, and 96 case reports or case series. Studies published between January 1, 2020, and January 16, 2021, were identified through a systematic search of online PubMed and MEDLINE databases. Random effects analyses of randomized clinical trials and matched control data demonstrated that patients with COVID-19 transfused with convalescent plasma exhibited a lower mortality rate compared with patients receiving standard treatments. Additional analyses showed that early transfusion (within 3 days of hospital admission) of higher titer plasma is associated with lower patient mortality. These data provide evidence favoring the efficacy of human convalescent plasma as a therapeutic agent in hospitalized patients with COVID-19.     

A Systematic Review of Virtual Reality Therapeutics for Acute Pain Management

ObjectivesThe purpose of this systematic review is to examine the delivery and clinical efficacy of virtual reality (VR) therapeutics for acute pain management in adults and identify practical considerations of VR deployment, as well as current gaps in the literature.DesignA systematic review.Data sourcesA search of PubMed, CINAHL, PsychINFO, Embase, Compendex, and Inspec was completed using Medical Subject Headings (MeSH) and keyword search terms related to acute pain and VR.Review/Analysis methodsA systematic review of all pertinent articles published between January 1, 2000, and August 1, 2020, was conducted according to the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) guidelines.ResultsTwenty-three articles met final inclusion criteria and were included in this review. Studies utilized VR in a variety of settings for wound care, procedure-induced pain, physical or occupational therapy, dental treatment or generalized acute pain. A likely mechanism by which VR promoted analgesia in these studies is distraction. Of the reviewed studies, 19 (83%) reported decreases in pain intensity while using VR compared with no VR use or with a non-VR group.ConclusionsThis systematic review found VR to be an effective tool for acute pain management. Findings from this review also underscore the importance of addressing the patient's sense of presence and levels of immersion, interaction, and interest when deploying VR. Future VR studies should consider incorporation of anxiety, presence, and VR side effect measures in addition to acute pain metrics.     

Effectiveness of micronutrients supplement in patients with active tuberculosis on treatment: Systematic review/Meta-analysis

BackgroundMultiple researchers have suggested the influence of micronutrients in the cure and survival of tuberculosis.ObjectiveTo determine the effectiveness of micronutrients in the cure and treatment of pulmonary tuberculosis.MethodsSystematic search of randomized controlled trials (RCTs) in databases of people under treatment for active pulmonary tuberculosis, that must have received oral micronutrients for at least four weeks compared with placebo. The synthesis of the variables was shown in standardized mean difference (MD) and/or risk difference (RD). The random effects model was used and was reported in forest plot of the estimates of the effect with a 95 % CI.ResultsSixteen of 246 studies were included, in total 4398 people. Zinc showed (RD, 0.04; 95 % CI, 0.00–0.08) in mortality, increases muscle mass index (MD, 1.20; 95 % CI, 0.04–2.36) and gains weight (MD, 3.10; 95 % CI, 0.66–5.54). Zinc plus vitamin A increases the weight (MD, 3.10; 95 % CI, 2.78–3.42), improving karnofsky scale (MD, 2.50; 95 % CI, 2.22–2.78). Additionally, vitamin D accelerate the sputum conversión time (RD, 0.38; 95 % CI, 0.03–0.73). Hemoglobin (Hb) with vitamin A and zinc achieves statistically significant changes (MD, 0.69; 95 % CI, 0.28–1.09) and (MD, 0.52; 95 % CI, 0.21–0.83) and reduces area of cavitations in chest X-ray (MD, -0.33; 95 % CI, -0.60–-0.06).ConclusionsThe consumption of micronutrients could achieve weight gain, hemoglobin, accelerated sputum conversion and improvement in quality of life. There are no changes in mortality that may be attributable to the suboptimal dose, larger studies are suggested with adequate doses.     

Effects of Tai Chi on Lower Limb Proprioception in Adults Aged Over 55: A Systematic Review and Meta-Analysis

ObjectiveTo summarize and critically evaluate the effects of Tai Chi on lower limb proprioception in adults older than 55.Data SourcesSeven databases (Scopus, PubMed, Web of Science, SPORTDiscus, Cochrane Library, Wanfang, CNKI) were searched from inception until April 14, 2018.Study SelectionEleven randomized controlled trials were included for meta-analysis.Data ExtractionTwo independent reviewers screened potentially relevant studies based on the inclusion criteria, extracted data, and assessed methodological quality of the eligible studies using the Physiotherapy Evidence Database (PEDro).Data SynthesisThe pooled effect size (standardized mean difference [SMD]) was calculated while the random-effects model was selected. Physiotherapy Evidence Database scores ranged from 5 to 8 points (mean=6.7). The study results showed that Tai Chi had significantly positive effects on lower limb joint proprioception. Effect sizes were moderate to large, including ankle plantar flexion (SMD=−0.55; 95% confidence interval [95% CI], −0.9 to −0.2; P=.002; I²=0%; n=162), dorsiflexion (SMD=−0.75; 95% CI, −1.11 to −0.39; P<.001; I²=0%; n=162), nondominant or left knee flexion (SMD=−0.71; 95% CI, −1.10 to −0.41; P<.001; I²=25.1%; n=266), dominant or right knee flexion (SMD=−0.82; 95% CI, −1.06 to −0.58; P<.001; I²=33.8%; n=464).ConclusionsThere is moderate to strong evidence that suggests that Tai Chi is an effective intervention to maintain and improve lower limb proprioception in adults older than 55. More robust multicenter studies including oldest-old participants, with longer follow-ups and validated outcome measures, are needed before a definitive conclusion is drawn.     

Content and Effectiveness of Interventions Focusing on Community Participation Poststroke: A Systematic Review

ObjectiveTo investigate the content and effectiveness of interventions that address poststroke community participation.Data SourcesEMBASE, PsycINFO, PubMed, and Cumulative Index to Nursing and Allied Health (CINAHL) were searched using 3 indexing terms and respective thesaurus: stroke, social participation, and clinical trials. Filters for English, publication dates (January 2001-May 2017), and publication types were used. The search also included checking references from relevant systematic reviews.Study SelectionStudies conducted with adults with stroke, evaluating interventions addressing community participation, having a comparison group, and reporting at least 1 of 3 outcomes (participation, depression, and health-related quality of life) were selected. Retrieved articles were screened by 2 reviewers. After substantial agreement was achieved using interrater reliability, reviewers screened articles independently. Eighteen of 1130 articles were included.Data ExtractionCharacteristics of participants, key elements of intervention, comparator, and results were independently extracted by 2 reviewers. Intervention content was categorized based on 9 categories from the International Classification of Functioning, Disability, and Health Activities and Participation domains. Risk of selection, performance, attrition, and reporting bias were evaluated.Data SynthesisTwo intervention categories were identified: leisure participation and community integration. Three leisure and 4 community integration interventions showed significant group differences favoring the intervention group in the target outcomes. The majority of interventions addressed the leisure, interpersonal relations, and community life categories of International Classification of Functioning, Disability, and Health with few focusing on political life, education, assisting others, and religion.ConclusionsA limited number of studies showed an effect on participation, depression, and health-related quality of life outcomes. There were gaps in intervention content indicating that current community participation interventions fall short in addressing full inclusion and citizenship of people with stroke. Future interventions should focus on civic- and societal-level participation and community activities beyond leisure.
