Non-invasive telemonitoring programs for patients with chronic heart failure: A systematic review and meta-analysis of randomized controlled trials.

To assess whether telemonitoring improves outcomes in patients with chronic heart failure. A literature search was conducted on studies of randomized controlled trials involving non-invasive telemonitoring and heart failure using Medline, Embase, and Cochrane Library. The primary outcomes were all-cause mortality, all-cause hospitalization, and hospitalization for heart failure. Secondary outcomes were length of stay, health-related quality of life as assessed by validated questionnaires, healthcare costs and cost-effectiveness, and self-care behaviors. We performed a meta-analysis using a random effects model for the primary outcomes. The effect measure was odds ratio with corresponding 95% confidence interval, and heterogeneity among studies was assessed using the Higgins I2 value. We screened 212 references, and 34 randomized controlled trials were included in this review. A total of 16179 participants with heart failure were included. Non-invasive telemonitoring reduced all-cause mortality by 18% (OR 0.82, 95% CI 0.71 to 0.95; participants = 15,211; studies = 28; I2 = 34%; GRADE: moderate-quality evidence) and heart failure hospitalization by 20% (OR 0.80, 95% CI 0.69 to 0.94; participants = 7491; studies = 18; I2 = 31%; GRADE: moderate-quality evidence). Non-invasive telemonitoring didn't demonstrate significant benefit on all-cause hospitalization (OR 0.93, 95% CI 0.82 to 1.05; participants = 11,565; studies = 25; I2 = 49%). Telemonitoring programs in patients with heart failure were associated with a reduction in all-cause mortality and heart failure hospitalization without harmful events.

Effects of cardiorespiratory physiotherapy on balance and gait in stroke: a network meta-analysis of randomised controlled trials

Purpose To investigate effects of various cardiorespiratory physiotherapy interventions on balance and gait in patients with stroke. Methods This systematic review and network meta-analysis searched PubMed, EMBASE, Cochrane Library, and Web of Science for articles from 2000 to 2023. Twenty-nine RCTs on stroke patients were selected, involving interventions like ground-based aerobic training (GBAT), resistance training (RT), aquatic training (AT), robot-assisted training (RAT), inspiratory training (IT), combined aerobic and resistance training (CART), and combined aerobic and breathing training (CABT). Outcome variables were Berg Balance Scale (BBS), 6-minute walk test (6MWT), and 10-meter walk test (10MWT) scores. Results The analysis included 29 articles with 1,370 participants. On the BBS, RT was the most effective (99.66%), significantly more than conventional training (CT) (mean, 95% CI: 1.538, 0.771–2.304). For the 6MWT, CABT ranked highest (85.39%), with all interventions except AT showing significant effects compared to no intervention (N). For the 10MWT, GBAT ranked highest (81.71%), with significant effects for N versus GBAT (0.744, 0.308–1.180) and CART (0.732, 0.257–1.207). Comparisons of CT versus CART and N versus IT in the 6MWT had moderate evidence quality. Conclusions The findings emphasise the importance of incorporating aerobic, strength, and respiratory exercises alongside conventional physical therapy for optimal outcomes.

Effects of aerobic, resistance and combined training on endothelial function and arterial stiffness in older adults: A systematic review and meta-analysis.

We conducted a systematic review of randomized clinical trials evaluating the effects of aerobic, resistance and/or combined training on flow-mediated dilation (FMD) and/or pulse wave velocity (PWV) in older adults. The studies were selected from the electronic databases PubMed, Cochrane, LILACS, EMBASE, Web of Science, and the gray literature. We assessed the studies using Cochrane risk of bias (RoB2) tool and the GRADE tool. The GRADE assessment showed moderate quality of evidence for aerobic training and resistance training and very low for combined training. The measures of effects are presented as mean differences of the intervention group versus the control group and related 95% confidence intervals (95% CIs) pooled by a random-effects model using an inverse variance method. Our analysis of 24 RCTs (Intervention group [n = 251]: 67.7 ± 5.6 years old; control group [n = 228]: 68.7 ± 5.9 years old) showed that aerobic training was effective to improve FMD (0.64% [95% CI 0.24 to 1.03], p = 0.002) and PWV (-1.21 m/s [95% CI -1.37 to -1.05], p< 0.001) by compared to the control group. The subgroup analyses showed no FMD differences following aerobic training in healthy adults when compared to those with any health condition. Combined training was effective in improving FMD (0.60% [95% CI 0.50 to 0.71], p< 0.001) and PWV (-0.79 m/s [95% CI -1.23 to -0.35], p = 0.002). But these same parameters did not show any improvement in response to resistance training. A major limitation of this study is that the analysis to evaluate the effect of resistance training on PWV include only one study, and no inferences could be made from the data. Aerobic and combined training, but not resistant training, improve flow-mediated dilation and pulse wave velocity in the elderly. PROSPERO: CRD42021275282.

Low-dose colchicine for stroke prevention: a systematic overview of systematic reviews and meta-analyses.

Stroke incidence remains a significant concern despite optimized prevention strategies. Colchicine shows potential for improving stroke prevention globally. To summarize efficacy and safety estimates from systematic reviews and meta-analyses (SRMAs) of randomized controlled trials (RCTs) comparing colchicine to usual care or placebo for stroke prevention. We conducted an overview of SRMAs according to the Preferred Reporting Items for Overviews of Reviews guidelines through a systematic search in Pubmed, Embase, and the Cochrane Library. Statistical analysis was performed using RevMan Web. Heterogeneity was assessed with I² statistics. Thirty-two studies were included. Colchicine significantly reduced stroke recurrence (RR 0.46; 95% CI 0.41-0.52; p < 0.0001; I² = 0%; OR 0.44, 95% CI 0.36-0.55; p < 0.0001; I² = 0%) but increased gastrointestinal adverse events (RR 1.54, 95% CI 1.33-1.79; p < 0.0001; I² = 63%; OR 1.60, 95% CI 1.08-2.38; p = 0.0007; I² = 82%). Most SRMAs (93.75%) showed reduced stroke incidence (RR 0.26-0.54), while 65.22% reported increased gastrointestinal events (RR 1.05-2.66). No significant differences were observed in mortality, infection or cancer rates. Overall quality was appraised as high in 28.12%, moderate in 6.25%, low in 40.06%, and critically low in 25% of SRMAs. Data were primarily derived from seven RCTs with low risk of bias. Moderate-quality evidence supports colchicine's benefits and reasonable safety for preventing stroke among high-risk populations. However, stroke was not the primary endpoint in analyzed studies. RCTs directly assessing colchicine for stroke prevention are warranted.

Dose-Response Associations Between Diet and Risk of Rheumatoid Arthritis: A Meta-Analysis of Prospective Cohort Studies.

To provide a systematic and quantitative summary of dietary factors and rheumatoid arthritis (RA) risk. A systematic review and meta-analysis included prospective cohort studies from 2000 to 2024 reporting relative risks (RRs) with 95% confidence intervals (CIs) for RA incidence relating to 32 different dietary exposures. Linear and non-linear dose-response analyses were conducted. Thirty studies were included, involving 2,986,747 participants with 9,677 RA cases. Linear dose-response analysis suggested that each 2-unit per week increase in total alcohol intake was linked to 4% risk reduction (RR (95%-CI), heterogeneity (I2), NutriGrade score: 0.96 (0.94, 0.98), 58%, moderate certainty), and beer consumption was associated with a 10% reduction per 2 units/week increase (0.90 (0.84, 0.97), 0%, very low certainty). Each 2-unit/week increase in total alcohol intake was associated with a 3% decrease in seropositive RA risk (0.97 (0.96, 0.99), 28%, moderate certainty). Increased intakes of fruit (per 80 g/day) and cereals (per 30 g/day) were associated with 5% (0.95 (0.92, 0.99), 57%, moderate certainty) and 3% (0.97 (0.96, 0.99), 20%, moderate certainty) reduced risk, respectively. Conversely, tea consumption showed a 4% increased risk per additional cup/day (1.04 (1.02, 1.05), 0%, moderate certainty). Non-linear associations were observed for total coffee, vegetables, oily fish, and vitamin D supplementation. Data on dietary patterns and specific micronutrients were limited. The findings suggest that moderate alcohol consumption and a higher intake of fruits, oily fish, and cereals are associated with a reduced risk of RA, while tea and coffee may be linked to an increased risk. Optimising dietary intake of certain food components may reduce RA risk, despite moderate-quality evidence.

Arthroscopic assisted versus open core decompression for osteonecrosis of the femoral head: A systematic review and meta-analysis.

Minimally invasive treatment options for osteonecrosis of the femoral head (ONFH) have been a prominent area of research in recent years. Arthroscopic-assisted treatments have been applied in the clinical management of ONFH; however, high-quality evidence verifying their effectiveness and safety is still lacking. To systematically assess the clinical efficacy and safety of arthroscopic-assisted core decompression (AACD) in treating ONFH. A comprehensive literature search was conducted in PubMed, Web of Science, EMBASE, Cochrane Library, Chinese National Knowledge Infrastructure, China Science and Technology Journal Database, WanFang, and the Chinese BioMedical Literature Database, from inception to June 25, 2024. We identified randomized controlled trials and non-randomized controlled studies on AACD for the treatment of ONFH based on predefined inclusion and exclusion criteria. A meta-analysis was performed using Review Manager 5.4.1 and Stata 17.0 software. The analyzed outcomes included operative time, intraoperative blood loss, length of hospital stay, postoperative femoral head collapse rate, Harris hip score, and postoperative complication rate. The Grades of Recommendations, Assessment, Development, and Evaluations (GRADE) system was used to assess the quality of evidence for the outcome indicators. A total of fourteen studies were included in this meta-analysis, comprising 1,063 patients-541 in the core decompression (CD) group and 522 in the AACD group. The meta-analysis revealed no significant differences between the two groups in terms of intraoperative blood loss, length of hospital stay, 12-month postoperative Harris hip score, or overall postoperative complication rate (P > 0.05). However, the AACD group had a longer operative time (MD = 31.19, 95% Cl: 5.32 to 57.07, P = 0.02) and a lower overall postoperative femoral head collapse rate (RR = 0.49, 95% Cl: 0.27 to 0.89, P = 0.02) compared with the CD group. Additionally, the AACD group showed significant improvements in Harris hip scores at 3 months (MD = 6.39, 95% Cl: 5.44 to 7.33, P < 0.00001), 6 months (MD = 7.56, 95% Cl: 6.63 to 8.49, P < 0.00001), ≥ 24 months (MD = 7.00, 95% Cl: 4.80 to 9.21, P < 0.00001), and at the last follow-up (MD = 6.89, 95% Cl: 5.30 to 8.48, P < 0.00001) compared to the CD group. The GRADE evidence assessment indicated that the overall postoperative complication rate was supported by moderate-quality evidence, while the evidence for operative time, intraoperative blood loss, postoperative femoral head collapse rate, and Harris hip score was of low quality. The evidence for length of hospital stay was deemed very low quality. This meta-analysis suggests that AACD is an effective and safe treatment for patients with ONFH. However, due to the limited quantity and quality of the included studies, these results should be interpreted with caution. Further high-quality studies are recommended to confirm these findings.

Effect of diet combined with exercise intervention on tumor necrosis factor α in overweight or obese groups: Based on the exercise dose-response relationship

Background: Chronic low-grade systemic inflammation, often linked to obesity or being overweight, is associated with various complications and an increased risk of disease development. Tumor necrosis factor α (TNF-α) is a key inflammatory factor that significantly impacts various body functions. Objective: 1) To assess whether combined interventions are more effective than single interventions in combining diet and exercise. 2) To assess the effectiveness of exercise dose in different interventions on tumor necrosis factor (TNF-α) levels in obese or overweight patients. Methods: A thorough search was conducted across four electronic databases of randomized controlled trials that focus on exercise or dietary interventions for patients with obesity or overweight. This comprehensive review encompasses data collected up to August 2024. Two independent researchers conducted a thorough evaluation of the literature's quality. Network and dose-response analyses were performed using random effects models to examine the impact of diverse interventions on TNF-α. Results: A total of 19 randomized controlled trials with 1479 patients with obesity or overweight were included. The meta-analysis showed that the hypocaloric diet combined with aerobic training (HDAT) possessed the highest ranking (SMD= -1.00,95%CI -1.51 to -0.49), followed by the hypocaloric diet (HD) (SMD= -0.40,95%CI -0.89 to 0.09), hypocaloric diet combined with resistance training (HDRT) (SMD= -0.48,95%CI- 1.43 to 0.48), and aerobic training combined with resistance training (ART) (SMD= -0.18,95%CI -0.92 to 0.57). Additionally, a notable improvement in TNF-α levels was observed in individuals adhering to a hypocaloric diet in conjunction with exercise when the cumulative exercise volume reached 150 metabolic equivalent of task minutes per week. Conclusion: Based on the GRADE rating guidelines, moderate-quality research evidence indicates that a hypocaloric diet combined with aerobic training (HDAT) is the most effective intervention for enhancing tumor TNF-α levels in individuals with obesity or overweight. Additionally, the dose-response relationship was observed between the total exercise dose and TNF-α levels. Future research should investigate the specific effects of various aerobic exercise modalities on TNF-α levels in obese or overweight patients to develop a more personalized approach to exercise prescription.

Neural mobilisation effects in nerve function and nerve structure of patients with peripheral neuropathic pain: A systematic review with meta-analysis.

To assess the effects of neural mobilisation on nerve function and nerve structure of patients with peripheral neuropathic pain. A systematic review with meta-analysis was conducted. Medline, Embase, CINAHL, Cochrane Library, and World Health Organization International Clinical Trials Registry Platform were searched without restrictions. Eligibility criteria included controlled trials or quasi-experimental studies comparing neural mobilisation versus sham, active or inactive control in adults with peripheral neuropathic pain. Primary outcomes were the change in peripheral nerve cross-sectional area. Secondary outcomes included nerve echogenicity, nerve excursion and nerve conduction. Random effects meta-analysis was conducted. Risk of bias was assessed with the Cochrane Collaboration tool, and certainty of evidence was assessed using the Grading of Recommendations Assessment, Development, and Evaluation framework. Eleven randomised controlled trials and four quasi-experimental studies (total sample = 722 participants) were included. Thirteen studies included participants with carpal tunnel syndrome. Two studies examined the cross-sectional area, revealing improvements (i.e., a reduction) in the cross-sectional area after the neural mobilisation. Neural mobilisation improved motor [mean difference = 2.95 (95%CI 1.67 to 4.22)] and sensory conduction velocity in short-term [mean difference = 11.74 (95%CI 7.06 to 16.43)], compared to control. Neural mobilisation did not alter distal motor or sensory latency. Neural mobilisation seems to improve (i.e., a reduced) the cross-sectional area (very low-quality evidence) and sensory conduction velocity (very low-quality evidence). Neural mobilisation was superior to control in improving motor conduction velocity in patients with peripheral neuropathic pain with moderate quality evidence. Distal motor or sensory latency presented similar results compared to other interventions. Our findings should be interpreted cautiously since most studies included patients with carpal tunnel syndrome.

Pericapsular nerve group block reduces opioid use and pain after hip surgery: A systematic review and meta-analysis of randomized controlled trials.

While the pericapsular nerve group (PENG) block has become increasingly popular for managing pain after hip surgery, its efficacy remains controversial. We systematically searched Pubmed, Web of Science, Embase, and the Cochrane Library for randomized controlled trials to assess current evidence about the efficacy of the PENG block. Patients who received PENG block were compared to those who received sham/no block in terms of opioid consumption and pain within 24h after surgery, time to first opioid requirement, functional recovery, risk of nausea and vomiting, and patient dissatisfaction. The quality of evidence was assessed using the "Grading of Recommendations Assessment, Development and Evaluation" (GRADE) system. We meta-analyzed six trials involving 416 patients who received preoperative PENG block and 415 who received sham/no block. Patients did not receive any other type of multimodal analgesia. Within 24 h after hip surgery, PENG block significantly reduced postoperative opioid consumption (MD = -12.03, 95% CI: -21.47 to -2.59, P < 0.01, I2 = 97%), particularly in subpopulations undergoing hip replacement, hip fracture, or who had spinal anesthesia, and it significantly decreased dynamic pain scores, but not static scores, without increasing risk of nausea or vomiting or patient dissatisfaction. Individual studies suggested that the PENG block can prolong the time to the first opioid requirement and can improve functional recovery. Most meta-analyses provided evidence of moderate quality according to the GRADE system. The available evidence indicates that preoperative PENG block can significantly decrease opioid consumption and pain early after hip surgery, and it may also promote early functional rehabilitation. However, the limited number of included studies and sample size make it difficult to draw firm conclusions. The decision on whether to apply the PENG block should take into account the patient's age and the type of surgery and anesthesia.

Effectiveness of telerehabilitation versus face-to-face pulmonary rehabilitation on physical function and quality of life in people with post COVID-19 condition: a systematic review and network meta-analysis.

Post COVID-19 condition (PCC) is characterized by the persistence of symptoms associated with COVID-19 infection for more than 12 weeks, with worsening quality of life and physical function deconditioning being among the most commonly reported persistent symptoms. Pulmonary rehabilitation has emerged as a safe and viable option for these patients. Administered either face-to-face (FTF) or telemedicine (TL), it has been shown to improve symptoms associated with PCC. However, little is known about which approach is best for this population. Therefore, we conducted a systematic review and network meta-analysis on the efficacy of FTF versus TL compared to usual care in improving physical function and quality of life (physical and mental) in patients with PCC. A systematic search of PubMed, Cochrane Library, and Web of Science was performed from 2020 to January 5th, 2024. Two independent reviewers performed study selection, data extraction, and risk of bias assessment; this selection included only randomized controlled trials. A network meta-analysis was performed to compare the effects of FTF and TL with usual care. Multivariate and univariate analysis were performed to evaluate the best intervention. Data were extracted from 10 studies, five of which were treated with FTF and five of which were TL, involving 765 adults with PCC, ranging in age from 22 to 66 years. Interventions consisted of isolated or combined exercises (aerobic, resistance, breathing) and lasted between three and ten weeks in most of the included studies. Multivariate analysis found that FTF produced significant differences compared to TL or usual care with moderate quality of evidence. Univariate analysis found that significant differences were only found for physical function and mental domain of quality of life for TL vs. usual care, with moderate quality of evidence. This study supports the use of FTF as a therapy to improve physical function and quality of life in patients with PCC. However, in the absence of differences between FTF and TL in the univariate model for any of the outcomes studied, the choice of the form of pulmonary rehabilitation administration should be individualized. Future studies should compare FTF with TL directly to clarify which is the best approach.

Effects of cognitive training on cognitive function in patients after cardiac surgery: A systematic review and meta-analysis of randomized controlled trials.

Postoperative cognitive deficits frequently occur in patients undergoing cardiac surgery, leaving them with reduced cognitive function. Cognitive training has been shown to improve cognitive function, however, the role in patients after cardiac surgery is unclear. In this study, we aimed to evaluate the effectiveness and safety of cognitive training in patients undergoing cardiac surgery. A systematic search of PubMed, Embase, Cochrane Library, CINAHL, Ovid Medline, Web of Science, CNKI, and Wanfang was conducted until March 2024. The risk of bias was assessed using the Cochrane Risk of Bias Tool. Data were meta-analyzed using RevMan 5.4 software. Potential bias and reliability of evidence were fairly assessed by using the Cochrane risk of bias method and the GRADE evidence grading method. A total of 16 studies involving 1335 cardiac surgery patients were included in this study. Compared with the control group, the cognitive training group had a significantly lower incidence of postoperative cognitive dysfunction (RR 0.35, 95% CI 0.18-0.65, P = .001), significantly improved cognitive function (MD 2.54, 95% CI 1.27-3.81, P < .001), and a significantly higher quality of life-mental component (MD 5.22, 95% CI 2.32-8.13, P < .001), anxiety (MD -6.05, 95% CI -10.96 to -1.15, P = .02) and depression (MD -3.97, 95% CI -7.15 to -0.80, P = .01) were significantly improved between groups. However, the differences were not statistically significant for postoperative delirium (RR 1, 95% CI 0.38-2.65, P = 1.00) and postoperative hospitalization (MD -0.95, 95% CI -2.90 to 1.00, P = .34). The present study, based on a low to moderate quality of evidence, suggests that cognitive training improves cognitive functioning, reduces the incidence of postoperative cognitive dysfunction, and has a positive impact on anxiety and depression in patients undergoing cardiac surgery. However, current evidence does not allow for the determination of effects on quality of life, postoperative delirium, and postoperative length of stay.

Measurement properties of patient-reported outcome measures for women with dysmenorrhea: A systematic review.

Dysmenorrhea, or menstrual pain, is a subjective experience, and can only be assessed by patient-reported outcomes. These instruments should be reliable, valid and responsive. To identify and critically appraise the available evidence for the measurement properties of specific patient-reported outcome measures used for dysmenorrhea. The PRISMA statement was used to report this systematic review. Databases searched were PubMed, SCOPUS, CINAHL, Web of Science, ScienceDirect and Google Scholar (April 2021; updated on February 2023). Original studies with primary data collection, with no restriction on language and publication date that reported psychometric properties of one or more dysmenorrhea-related patient-reported outcome measure. The literature searches, selection of studies, data extraction and assessment of the risk of bias were performed independently by two reviewers and followed the COSMIN guidelines. Thirty studies were analysed in this review, and 19 patient-reported outcome measures were evaluated. The instruments varied in relation to the measured construct and measurement properties (validity, reliability and responsiveness). The methodological quality of the studies and the quality of evidence of the patient-reported outcome measures were variable. Among the 13 studies that reported the development of patient-reported outcome measures, most had inadequate methodological quality, and the overall rating was insufficient or inconsistent. The Dysmenorrhea Symptom Interference (DSI) scale was the only identified patient-reported outcome measure that has the potential to be recommended because of its sufficient rating combined with moderate quality of evidence for content validity. Future studies should further evaluate the measurement properties of the existing patient-reported outcome measures, or develop new patient-reported outcome measures following the COSMIN methodology. Not applicable as this is a systematic review. PROSPERO protocol: CRD42021244410. Registration on April 22, 2021.

The Effectiveness of Neural Mobilization in Patients with Tarsal Tunnel Syndrome: A Systematic Review and Meta-Analysis

Background: Tarsal Tunnel Syndrome (TTS) is a compression neuropathy, occurring when the distal branches of the posterior tibial nerve become entrapped within the tarsal tunnel, with no definitive evidence for its conservative management. Neural mobilization, a therapeutic approach involving joint and peripheral nerve movement, seeks to restore the nervous system’s homeostasis. There is currently insufficient evidence to determine the efficacy of neural mobilization. Objectives: Analysis of data from randomized controlled trials (RCTs) examining the efficacy of neural mobilization techniques (NMT) in TTS patients. Methods: A thorough search was carried out from inception until September 2024 utilizing four scientific databases (PubMed, Scopus, EMBASE, and Physiotherapy Evidence Database-PEDro) and the Google Scholar search engine. Relevant English-language research was retrieved, assessed, and given an independent methodological quality rating (PEDro scale). Meta-analyses were conducted for select outcomes, where possible. Results: 745 studies were eliminated from the total of 748 because they were duplicates or did not fit the inclusion criteria. Three RCTs were finally included, rated on average with 6.67/10 for methodological quality (PEDro scale). NMT led to a highly significant improvement of the nerve’s physiological sensitivity (p0.001), measured with the Tinel’s sign, based on evidence of high methodological quality (7.5/10) and no heterogeneity. NMT did not lead to a significant diminution of pain intensity (p=0.21) based on evidence of moderate methodological quality (6.67/10). Significant improvements in favour of NMT, however measured in one out of three studies, were identified for 2-point discrimination and light touch, the Neuropathic Pain Questionnaire, and the Functional Foot Index (p0.05). No adverse events were reported. All studies measured change immediately post-treatment. Conclusion: NMT significantly improved the tibial nerve’s mechanosensitivity. Moreover, as part of the treatment of patients with TTS, high-quality RCTs are necessary to examine the short and longer-term effects of NMT.

Spinal hyperexcitability in patients with chronic musculoskeletal pain or headache as evidenced by alterations in the nociceptive withdrawal reflex: a systematic review and meta-analysis.

The nociceptive withdrawal reflex (NWR) is a spinal withdrawal reflex induced by painful stimulation. It is a measure of spinal hyperexcitability, which is believed to contribute to chronic musculoskeletal pain (MSKP) and headache. Previous syntheses of the evidence for alterations in the NWR in patients with chronic MSKP and headache needed a comprehensive update. This systematic review and meta-analysis was performed after the Preferred Items for Systematic reviews and Meta-Analyses guidelines. Studies examining NWR-related outcome measures in patients with chronic MSKP and headache compared to pain-free controls were identified through electronic database searches and included after screening against predefined eligibility criteria. Standardized mean differences or mean differences and 95% confidence intervals (CI) were calculated. Thirty-one studies were included in the systematic review and 25 in the meta-analysis. Moderate-quality evidence was found indicating lower NWR threshold (-3.68; 95% CI, -4.56 to -2.80; P < 0.001), larger NWR area (standardized mean difference = 0.69; 95% CI, 0.37-1.01; P < 0.001), and shorter NWR latency (mean difference = -13.68; 95% CI, -22.69, -4.67; P = 0.003) in patients compared to controls. These findings remained robust when performing meta-regressions based on subgroups (ie, headache, fibromyalgia, whiplash-associated disorder, and osteoarthritis). Low-quality evidence demonstrated facilitated temporal summation of NWR threshold (-2.48; 95% CI, -3.13 to -1.83; P < 0.001) in patients compared to controls. Spinal hyperexcitability as evidenced by lowered NWR threshold values and temporal summation of the NWR is present in patients with chronic MSKP and headache. No evidence was found for alterations in NWR duration and NWR magnitude. Future research is needed to address the gap in research on NWR-related outcome measures other than NWR threshold.

Effects of olanzapine in the improvement of body weight and appetite in patients with cancer or receiving chemotherapy: a systematic review and meta-analysis.

We aimed to assess the effects of olanzapine in the improvement of body weight and appetite in patients with cancer or receiving chemotherapy through a systematic review and meta-analysis. We searched the following databases from their inception to April 23, 2024: Embase, PubMed, Web of Science, and the Cochrane Library. The mean difference (MD) and risk ratios were used to calculate by random effects models. The primary outcome was the proportion of patients with > 5% weight gain. Seventeen studies with 3457 participants were included. For primary outcomes, 1 study with 124 participants showed olanzapine increased the proportion of patients with > 5% weight gain compared with placebo (60% vs. 9%, P < 0.001). Versus active controls (3 studies, 439 participants), no significant difference in the proportion of patients with > 5% weight gain (RR = 1.69, 95%CI: 0.91 to 3.13, I2 = 27%, P = 0.10), with moderate-quality evidence. Olanzapine increased appetite scores compared to both placebo (1 study, 112 participants; MD = 3, 95%CI: 2.3 to 3.7, P < 0.001) and active controls (2 studies, 106 participants; MD = 4.96, 95%CI: 4.61 to 5.30, I2 = 0%, P < 0.01). For mean weight change, olanzapine showed no significant differences versus placebo (2 studies, 164 participants, MD = 2.78kg, 95%CI: - 1.60 to 7.17, I2 = 48%, P = 0.21) or active controls (2 studies, 480 participants, MD = 0.44kg, 95%CI: - 1.04 to 1.91, I2 = 58%, P = 0.56). Olanzapine appears to be a potential option for improving appetite and weight gain in cancer patients. Future trials need to focus on the optimal target dose and use durations of olanzapine.

Educational programmes for improving medication adherence among older adults with coronary artery disease: a systematic review and meta-analysis

Abstract Background Coronary artery disease (CAD) is the leading cause of death worldwide. Adhering to CAD medications is the priority of its treatment. However, medication adherence is suboptimal among older adults with CAD. Educational programmes are widely used and recommended in improving medication adherence among older adults with CAD. However, the evidence about the effects of educational programmes on medication adherence among older adults with CAD is limited. Aim To evaluate the best available research evidence on the effects of educational programmes designed for improving medication adherence among older adults with CAD. Methods 12 English databases and five Chinese databases were searched from inception to January 2024. Randomised controlled trials or quasi-experimental studies examining the effects of educational programmes for improving medication adherence among older adults with CAD were included. The educational programmes included a set of planned activities aiming at improving the knowledge, attitudes, and skills of medication adherence. The outcome of medication adherence was measured by either objective or subjective methods. The quality of the included studies was assessed by the Cochrane Risk of Bias Tool v2 or the Risk of Bias In Non-randomised Studies of Interventions tool. Meta-analysis was conducted using random-effect models as appropriate. Narrative synthesis was conducted if the results of the included studies were not appropriate or possible for meta-analysis. The Grading of Recommendations, Assessment, Development, and Evaluation Approach was used to assess the certainty of evidence. Results 5,607 records were retrieved and 5,599 records were excluded. Seven studies including six randomised controlled trials and one quasi-experimental study were included. Two studies were rated as low risk of bias. Five studies were rated as some concerns or moderate risk of bias due to inadequate information on blinding, allocation concealment, and the analysis of data according to the intention-to-treat principle. The results showed that the educational programmes were associated with significant improvements in medication adherence at immediately post-intervention (Standardised mean difference (SMD): 1.61, 95% CI: 0.03 to 3.19, P=0.05, Low quality of evidence), and at one to six months post-intervention (SMD: 1.13, 95% CI: 0.33 to 1.94, P=0.006, Moderate quality of evidence). Narrative synthesis found that the educational programmes potentially improved medication adherence over six months post-intervention. Conclusions The results show that the educational programmes could improve medication adherence among older adults with CAD. Designing the educational programmes with theoretical frameworks would be helpful to address the complex health needs of the older adults with CAD. More rigorous evaluation of the effectiveness of the programmes on long-term medication adherence of the older adults is warranted.Figure 1.Immediate post-interventionFigure 2.Medium-term post-intervention

The effect of prescription and over-the-counter medications on core temperature in adults during heat stress: a systematic review and meta-analysis

Heat stress impacts are an escalating global health concern. Public health bodies such as the World Health Organization (WHO) warn that certain medications impair thermoregulation, with limited supporting evidence. Our aim was to investigate whether medications listed by the WHO increase core temperature responses during heat stress. For this systematic review and meta-analysis, MEDLINE, PubMed, Scopus, CINAHL, Web of Science, and EMBASE were searched up to Jan.30, 2024. Randomised studies exposing humans to exertional and/or passive heat stress that investigated a drug identified by WHO compared to no drug/placebo were eligible. The primary outcome was core temperature (e.g., rectal, oesophageal, aural, tympanic). We assessed risk of bias (Cochrane's Risk of Bias 2) and certainty of evidence (GRADE). The study was pre-registered on PROSPERO (CRD42020170684). Thirty-five studies were included enrolling 353 individuals (16 women; 4.5%). Twenty-seven unique medications were tested. The average age of participants across studies was <30 years, and only one study included a clinical population. Under heat stress, there was moderate quality evidence that drugs with high anticholinergic properties increased core temperature at air temperatures ≥30°C (+0.42°C; 95% CI 0.04, 0.79°C; p=0.03) alongside reduced sweating, although evidence is limited to the drug atropine. Similarly, non-selective beta-blockers (+0.11°C; 95% CI 0.02, 0.19°C; p=0.02), adrenaline (+0.41°C; 95% CI 0.21, 0.61°C) and anti-Parkinson's agents (+0.13°C; 95% CI 0.07, 0.19°C; p=0.02) elevated core temperature. Antidepressants, diuretics, or drugs with weak anticholinergic effects did not alter core temperature responses. Current evidence supports strong anticholinergics, non-selective beta-blockers, adrenaline, and anti-Parkinson's agents impairing thermoregulation during heat stress. No evidence indicated thermoregulation is impacted by other WHO-listed medications. Evidence is predominantly limited to healthy young men, with short heat stress exposures. Studies over longer durations, in women, older adults and those with chronic diseases are required to better inform the pharmaceutical management of patients during hot weather. This study was supported by a National Health and Medical Research Council (NHMRC) Investigator Grant (2021/GNT2009507; Holder: O. Jay).

Lupus activity and pregnancy outcomes in systemic lupus erythematosus patients undergoing assisted reproductive therapy: A systematic review and meta-analysis.

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease primarily impacting women of childbearing age. While pregnancy and hormonal stress can trigger SLE flare-ups, the effects of assisted reproductive therapies (ARTs) on SLE patients are not well defined. We conducted a search of PubMed/Medline, Embase, and CENTRAL until March 20, 2024, to find observational studies assessing the prevalence of SLE flares and pregnancy outcomes following ARTs. Our analysis included random-effects meta-analysis and the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach for evaluating evidence quality. Five studies involving 237 SLE women who underwent ARTs were eligible. The meta-analysis indicated a prevalence of SLE flares at 17% (95% CI: 10-25%) with moderate-quality evidence. The pooled prevalence of arthritis flares was 7% (95% CI: 0-25%) with low-quality evidence. Successful pregnancy rates were 58% (95% CI: 43-72%), and live birth rates were 96% (95% CI: 83-100%), both with low-quality evidence. Moderate-quality evidence showed pregnancy complications, including preterm premature rupture of membranes (PPROM) at 8% (95% CI: 3-16%), miscarriages at 2% (95% CI: 0-9%), intrauterine fetal demise (IUFD) at 4% (95% CI: 0-11%), and preeclampsia at 7% (95% CI: 1-17%). Low-quality evidence showed preterm labor at 10% (95% CI: 0-32%) and ovarian hyperstimulation syndrome (OHSS) at 2% (95% CI: 0-11%). SLE flares, as well as pregnancy complications such as IUFD, miscarriage, PPROM, and preeclampsia in ART recipients, are equivalent to those in spontaneous conception. This indicates that ART is relatively safe for SLE patients with meticulous pregnancy planning. Key Points •Systemic lupus erythematosus (SLE) is a chronic autoimmune disease primarily impacting women of childbearing age. • Pregnancy in women with SLE poses elevated maternal and fetal risks compared to healthy women. • SLE flares and pregnancy complications while receiving ART are equivalent to those in spontaneous conception and ART is relatively safe for SLE patients.

Early mobilization in patients with aneurysmal subarachnoid haemorrhage may im-prove functional status and reduce cerebral vasospasm rate: a systematic review with meta-analysis.

The primary aim of this study was to evaluate the safety and efficacy of early mobilization in patients with aneurysmal subarachnoid haemorrhage. Systematic review with meta-analysis of randomized controlled studies and observational studies. Patients with aneurysmal subarachnoid haemorrhage. PubMed, Embase, CINAHL, Web of Science, Pedro, and the Cochrane Library databases were searched. A systematic review and meta-analysis were performed. Screening and data extraction were performed by 2 independent reviewers. Sixteen studies involving 1,757 patients were included. Meta-analysis of the data estimated that early mobilization improved mRS score at discharge (mean difference -1.39, 95% CI -2.51 to -0.28, I2 = 86%) and at 3 months (mean difference -1.10, 95% CI -1.54 to -0.66, I2 = 7%). Early mobilization was associated with a reduction in cerebral vasospasm rate, both radiological (OR 0.66, 95% CI 0.45 to 0.96, I2 = 7%) and clinical (OR 0.44, 95% CI 0.27 to 0.72, I2 = 8%); 6% of mobilization sessions involved adverse events, mostly haemodynamic changes. This review found moderate-quality evidence supporting the safety and effectiveness of early mobilization in patients with SAH. Further randomized controlled trials are needed to identify the appropriate mobilization strategy and confirm these results.

Effect of different electric stimulation modalities on pain and functionality of patients with pelvic pain: Systematic review with META-analysis.

Pelvic pain is located in the anterior abdominal wall, below the umbilical scar. Its treatment includes pharmacological therapy, which can cause adverse effects and is not always sufficient to control symptoms. Thus, the use of adjunct therapies such as electric stimulation has been suggested. Therefore, this review intends to appraise the literature on the effectiveness of electrostimulation in the treatment of pelvic pain. The search for studies was conducted until April 2024 in PubMed, Cochrane Library, ScienceDirect, SciELO, PEDro, CINAHL, BVS, Web of Science, Scopus, and Google Scholar databases using a combination of Mesh terms "Electric Stimulation" and "Pelvic Pain." Risk of bias assessment and meta-analysis were performed with The Cochrane Collaboration tool (RevMan 5.4). Quality of the evidence was assessed with GRADE tool. From the 3247 studies found, 19 were included. In the qualitative analysis, seven studies showed TENS, electroacupuncture, PTNS, and tDCS reduced pain intensity, one study on PTNS showed increased quality of life, and one on tDCS showed improved functional performance. However, in the meta-analysis, only TENS showed efficacy for the reduction of acute pelvic pain and primary dysmenorrhea. Our results indicate that there is moderate-quality evidence for TENS to reduce pain intensity in primary dysmenorrhea and low-quality evidence for the same outcome in acute pelvic pain. Randomized controlled clinical trials with larger sample size and with better methodological quality are needed to establish the effectiveness of other forms of electrical stimulation in pelvic pain.
