Comparison of various doses of oral cannabidiol for treating refractory epilepsy indications: a network meta-analysis.

Aim: To evaluate the comparative efficacy and safety of various doses of oral cannabidiol (CBD) in treating refractory epilepsy indications, thus providing more informative evidence for clinical decision-making. Methods: A literature search of PubMed, Embase, the Cochrane library, and Web of Science (WoS) was performed to retrieve relevant randomized controlled trials (RCTs) that compared different doses of oral CBD with placebo or each other in refractory epilepsy indications. The search was limited from the inception of each database to January 3, 2023. Relative risk [RR] with a 95% confidence interval [CI] was used to express results. STATA/SE 14 was employed for network meta-analysis. Results: Six RCTs involving 972 patients were included in the final data analysis. Network meta-analysis showed that, CBD10 (10 mg/kg/day) (RR: 1.77, 95%CI: 1.28 to 2.44), CBD20 (20 mg/kg/day) (RR: 1.91, 95%CI: 1.49 to 2.46), CBD25 (25 mg/kg/day) (RR: 1.61, 95%CI: 0.96 to 2.70), and CBD50 (50 mg/kg/day) (RR: 1.78, 95%CI: 1.07 to 2.94) were associated with higher antiseizure efficacy although the pooled result for CBD25 was only close to significant. In addition, in terms of the risk of treatment-emergent adverse events (TEAEs), the difference between different doses is not significant. However, CBD20 ranked first in terms of antiseizure efficacy, followed by CBD50, CBD10, and CBD25. For TEAEs, CBD25 ranked first, followed by CBD10, CBD50, CBD5, and CBD20. Conclusion: For refractory indications, CBD20 may be optimal option for antiseizure efficacy; however, CBD25 may be best for TEAEs. Therefore, an appropriate dose of oral CBD should be selected based on the actual situation. Due to the limitations of eligible studies and the limited sample size, more studies are needed in the future to validate our findings.

Priority interventions for the prevention of falls or fractures in patients with osteoporosis: A network meta-analysis.

BACKGROUND: The fractures of patients with osteoporosis represent a major health care burden that requires efficient prevention. OBJECTIVE: To analyze the efficacy and significance of diverse interventions for preventing falls or fractures in patients with osteoporosis, and to establish a foundation for clinical interventions. METHODS: Ten databases were searched for studies published before January 30, 2024. Screening, data extraction, and risk of bias assessment were independently conducted by two researchers using Stata 14.0 software. A network meta-analysis using the frequentist framework was then performed to determine the effectiveness of various interventions for preventing and managing falls and fractures in patients with osteoporosis. The findings were used as basis for the prioritization of interventions. RESULTS: The initial search yielded 3894 studies. After 3878 studies were excluded, 16 studies were finally included. For the prevention of falls in patients with osteoporosis, effective interventions include exercise and exercise plus medication. A combination of exercise, assessment and modifications, quality improvement strategies, social engagement, basic falls risk assessment, and assistive technology may be the preferred recommended intervention. For the prevention of fractures in patients with osteoporosis, no statistically significant disparities were observed among the compared interventions, exercise may be the preferred recommended intervention. CONCLUSION: Exercise and exercise plus medication are effective in reducing the number of falls in patients with osteoporosis. Although exercise may be the optimal intervention for fracture prevention, the quality of current evidence remains inadequate. Large-scale high-quality randomized controlled trials are necessary to substantiate these findings. TRIAL REGISTRATION: PROSPERO CRD42024507487.

Efficacy and safety of different polymyxin-containing regimens for the treatment of pneumonia caused by multidrug-resistant gram-negative bacteria: a systematic review and network meta-analysis.

BACKGROUND: The optimal administration of polymyxins for treating multidrug-resistant gram-negative bacterial (MDR-GNB) pneumonia remains unclear. This study aimed to systematically assess the efficacy and safety of three polymyxin-containing regimens by conducting a comprehensive network meta-analysis. METHODS: We comprehensively searched nine databases. Overall mortality was the primary outcome, whereas the secondary outcomes encompassed microbial eradication rate, clinical success, acute kidney injury, and incidence of bronchospasm. Extracted study data were analyzed by pairwise and network meta-analyses. Version 2 of the Cochrane risk-of-bias tool and the Risk of Bias in Nonrandomized Studies of Interventions (ROBINS-I) assessment tool were used to assess the risk of bias in randomized trials and cohort studies, respectively. RESULTS: This study included 19 observational studies and 3 randomized controlled trials (RCTs), encompassing 3318 patients. Six studies with high risk of bias were excluded from the primary analysis. In the pairwise meta-analysis, compared to the intravenous (IV) polymyxin-containing regimen, the intravenous plus inhaled (IV + IH) polymyxin-containing regimen showed a significant decrease in overall mortality, while no statistically significant difference was found in the inhaled (IH) polymyxin-containing regimen. The network meta-analysis indicated that the IV + IH polymyxin-containing regimen had significantly lower overall mortality (OR 0.67; 95% confidence interval [CI] 0.50-0.88), higher clinical success rate (OR 1.90; 95% CI 1.20-3.00), better microbial eradication rate (OR 2.70; 95% CI 1.90-3.90) than the IV polymyxin-containing regimen, and significantly better microbial eradication rate when compared with the IH polymyxin-containing regimen (OR 2.30; 95% CI 1.30-4.20). Furthermore, compared with IV + IH and IV polymyxin-containing regimens, the IH polymyxin-containing regimen showed a significant reduction in acute kidney injury. CONCLUSIONS: Our study indicates that among the three administration regimens, the IV + IH polymyxin-containing regimen may be the most effective for treating MDR-GNB pneumonia, with a significantly lower overall mortality compared to the IV regimen and a considerably higher microbial eradication rate compared to the IH regimen. The IH regimen may be considered superior to the IV regimen due to its substantially lower incidence of acute kidney injury, even though the reduction in overall mortality was not significant.

Comparing different postoperative sedation strategies for patients in the intensive care unit after cardiac surgery: A systematic review of randomized controlled trials and network meta-analysis.

BACKGROUND: Various postoperative sedation protocols with different anaesthetics lead to profound effects on the outcomes for post-cardiac surgery patients. However, a comprehensive analysis of optimal postoperative sedation strategies for patients in the intensive care unit (ICU) after cardiac surgery is lacking. METHODS: We systematically searched for randomized controlled trials (RCTs) in databases including PubMed and Embase. The primary outcome measured the duration of mechanical ventilation (MV) in the ICU, and the secondary outcome encompassed the length of stay (LOS) in the ICU and hospital and the monitoring adverse events. RESULTS: The literature included 18 RCTs (1652 patients) with 13 sedation regimens. Dexmedetomidine plus ketamine and sevoflurane were associated with a significantly reduced duration of MV when compared with propofol. Our results also suggested that dexmedetomidine plus ketamine may associated with a shorter LOS in ICU, and sevoflurane associated with a shorter LOS in the hospital, respectively. CONCLUSIONS: The combination of dexmedetomidine and ketamine seems to be a better option for adult patients needing sedation after cardiac surgery, and the incidence of side effects is lower with dexmedetomidine. These findings have potential implications for medication management in the perioperative pharmacotherapy of cardiac surgery patients.

The Clinical Effect and Safety of Dihuang Decoction in Henoch-Schönlein Purpura Compared With Different Traditional Programs: A Network Meta-Analysis.

This systematic review aims to evaluate the therapeutic efficacy of Dihuang decoction (DD), anti-inflammatory drugs (AIDs), blood circulation improvement drugs (BCIDs), and conventional therapy (CT) in the management of Henoch-Schönlein purpura (HSP) and to establish their comparative effectiveness rankings. Using the Population, Intervention, Comparison, Outcome, Study (PICOS) design framework, we developed a detailed search strategy. The literature search included databases such as PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure, Wanfang Data, Weipu Journal Data, and the Chinese Biomedical Database, covering studies published up to June 2024. We included randomized controlled trials that featured the DD as the experimental intervention, with three remaining treatments as comparators. Our analysis encompassed 63 studies with 5,435 participants, divided into 2,817 in the experimental group and 2,618 in the control group. The network meta-analysis suggested that the DD potentially surpasses AIDs, BCIDs, and CT in the management of HSP. This conclusion is supported by its superior SUCRA (Surface Under the Cumulative Ranking) scores across various measures, including the overall effective rate of medication, time to relief or disappearance of the rash, incidence of adverse reactions, time to relief or disappearance of abdominal pain, time to relief or disappearance of arthritic swelling or pain, IgA levels, and the relapse rate within six months (SUCRA scores: 100.0%, 88.3%, 79.8%, 94.4%, 99.9%, 88.3%, and 95.4%, respectively). In terms of overall effectiveness rate, the SUCRA efficacy rankings are as follows: DD > AIDs > AIDs+BCID > BCID > CT. Regarding rash relief and regression time, the SUCRA efficacy rankings are as follows: DD > CT > AIDs+BCID > AIDs. For the incidence rate of adverse reactions, the SUCRA efficacy rankings are as follows: DD > CT > AIDs > BCID > AIDs+BCID. For the relief and disappearance of abdominal pain, the SUCRA efficacy rankings are as follows: DD > CT > AIDs+BCID > AIDs. In terms of relief and disappearance of joint swelling and pain, the SUCRA efficacy rankings are as follows: DD > AIDs+BCID > AIDs. Regarding IgA changes, the SUCRA efficacy rankings are as follows: DD > CT > BCID > AIDs+BCID > AIDs. For the six-month recurrence rate, the SUCRA efficacy rankings are as follows: DD > AIDs > AIDs+BCID > CT. The DD appears to be a more effective alternative for treating HSP compared to AIDs, BCIDs, and CT. We hope that this study will provide better assistance to clinical practice.

Comparative Efficacy of Neoadjuvant Nivolumab Plus Chemotherapy versus Conventional Comparator Treatments in Resectable Non-Small-Cell Lung Cancer: A Systematic Literature Review and Network Meta-Analysis.

BACKGROUND: This study aimed to estimate the relative efficacy of neoadjuvant nivolumab in combination with chemotherapy (neoNIVO + CT) compared to relevant treatments amongst resectable non-metastatic non-small-cell lung cancer (rNSCLC) patients. METHODS: Treatment comparisons were based on a network meta-analysis (NMA) using randomized clinical trial data identified via systematic literature review (SLR). The outcomes of interest were event-free survival (EFS) and pathological complete response (pCR). NeoNIVO + CT was compared to neoadjuvant chemotherapy (neoCT), neoadjuvant chemoradiotherapy (neoCRT), adjuvant chemotherapy (adjCT), and surgery alone (S). Due to the potential for effect modification by stage, all-stage and stage-specific networks were considered. Fixed-effect (FE) and random-effects Bayesian NMA models were run (EFS = hazard ratios [HR]; pCR = odds ratios [OR]; 95% credible intervals [CrI]). RESULTS: Sixty-one RCTs were identified (base case = 9 RCTs [n = 1978 patients]). In the all-stages FE model, neoNIVO + CT had statistically significant EFS improvements relative to neoCT (HR = 0.68 [95% CrI: 0.49, 0.94]), S (0.59 [0.42, 0.82]), adjCT (0.66 [0.45, 0.96]), but not relative to neoCRT (HR = 0.77 [0.52, 1.16]). NeoNIVO + CT (5 RCTs) had statistically significant higher odds of pCR relative to neoCT (OR = 12.53 [5.60, 33.82]) and neoCRT (7.15 [2.31, 24.34]). Stage-specific model findings were consistent. CONCLUSIONS: This NMA signals improved EFS and/or pCR of neoNIVO + CT relative to comparators among patients with rNSCLC.

The analgetic effect of adjuvants in local infiltration analgesia - a systematic review with network meta-analysis of randomized trials.

BACKGROUND: Local infiltration analgesia is commonly used for postoperative pain control after several surgical procedures including intra- and peri-articular as well as wound infiltration. Even though, various adjuvants injected with the local anesthetic have been studied in pairwise comparison or compared to peripheral nerve blocks, the question which adjuvant or combination of adjuvants is the most effective in prolonging the duration of different types of local infiltration analgesia (LIA) has not been answered conclusively. OBJECTIVE: The objective of this network meta-analysis was to determine the analgesic effectiveness and safety of adjuvants in local infiltration analgesia. DESIGN: Systematic review of randomized controlled trials with network meta-analyses. DATA SOURCES: A comprehensive literature search in Embase, CENTRAL, MEDLINE and Web of Science was performed up to March 2023. RESULTS: The best interventions to prolong the duration of analgesia were dexamethasone (Ratio of Means (ROM) 3.33) followed by the combinations of clonidine + morphine (ROM 3.35) and morphine + magnesium sulfate (ROM 2.92), fentanyl (ROM 2.27), ketorolac (ROM 2.26), buprenorphine (ROM 2.04), morphine (ROM 1.93), magnesium sulfate (ROM 1.91), clonidine (ROM 1.89), dexmedetomidine (ROM 1.74) and tramadol (ROM 1.58). Serious adverse events were not reported with either investigated adjuvant. CONCLUSION: There is moderate evidence that dexamethasone is the most effective adjuvant to prolong the duration of analgesia in LIA. The evidence for the alpha-2 agonists dexmedetomidine and clonidine is also moderate, but their effectivity to prolong analgesia stays behind dexamethasone. Clonidine and dexmedetomidine had a small detectable effect on pain scores, yet below clinical relevance, but the largest effect on MEQ consumption. The effects of different opioids were homogenous for all endpoints. The prespecified subgroup analysis of LIA of the knee did not show significantly different results than the pooled analysis.

Effect of testosterone replacement therapy on lower urinary tract symptoms: A systematic review and network meta-analysis.

OBJECTIVE: In this study, we aimed to perform a network meta-analysis (NMA) to investigate the effects of different testosterone replacement therapy (TRT) administration routes on lower urinary tract symptoms (LUTS) in aging men with late-onset hypogonadism (LOH). METHODS: A systematic search of PubMed, Embase, The Cochrane Library, CNKI, WanFang Data, and VIP was conducted to identify randomized controlled trials (RCTs) reporting data on International Prostate Symptom Score (IPSS), prostate-specific antigen (PSA) level, or prostate volume. NMA was performed, and subgroup analysis was conducted to assess the impact of TRT duration on outcomes. RESULTS: A total of 21 RCTs involving 2453 participants were included. For pairwise meta-analysis, p values for TRT delivered by transdermal, intramuscular, and oral routes were as follows: IPSS: 0.93, 0.20, and 0.76; PSA level: 0.20, 0.27, and 0.98; prostate volume: 0.18, 0.04, and 0.16. There were no significant differences in IPSS, PSA level, or prostate volume between TRT routes. In subgroup analysis, long-term intramuscular TRT significantly decreased IPSS (p = 0.03), short-term transdermal TRT increased PSA levels (p < 0.001), and short-term intramuscular TRT increased the prostate volume (p = 0.04). Other forms of TRT showed no significant change in IPSS, PSA level, and prostate volume compared with the placebo. Indirect comparison of the three administration routes demonstrated no significant differences in IPSS, PSA level, and prostate volume. Nevertheless, surface under the cumulative ranking curve analysis indicated that intramuscular TRT had an 83% probability of being the best method for decreasing IPSS. CONCLUSIONS: The results demonstrate that TRT does not worsen LUTS regardless of the administration route. Intramuscular TRT may be the preferred treatment for aging men with LOH and LUTS. Intramuscular TRT may be the preferred treatment for men with LOH and LUTS. Further research is warranted to validate these findings and optimize TRT management strategies.

Efficacy and safety of pharmacological treatments for autoimmune disease-associated interstitial lung disease: A systematic review and network meta-analysis.

BACKGROUND: Immunosuppressants, biologic agents, antifibrotic drugs, and other drugs can be used to treat autoimmune disease-associated interstitial lung disease (ILD), but the preferred treatment is uncertain. We aimed to evaluate the efficacy and safety of multiple drugs in the treatment of autoimmune disease-associated ILD. METHODS: PubMed, Embase, Web of Science, Cochrane Central Register of Controlled Trials and ClinicalTrials.gov were searched for relevant randomized controlled trials (RCTs) from inception to July 2023. Primary outcomes were percentage of predicted forced vital capacity (FVC% predicted) and discontinuations for adverse events (AEs). We estimated summary mean differences (MDs) and odds ratios (ORs) using network meta-analysis with fixed effects. RESULTS: The analysis is based on 15 RCTs involving 1832 patients. In terms of FVC% predicted, mycophenolate mofetil (MMF) (MD 1.27, 95 % credible interval [CrI] 0.08 to 2.43), cyclophosphamide (1.89, 0.10 to 3.68), rituximab (9.29, 2.79 to 15.80), tocilizumab (6.30, 3.27 to 9.34), nintedanib (1.71, 0.54 to 2.88), pirfenidone (2.03, 0.65 to 3.40) and nintedanib+MMF (2.43, 0.95 to 3.89) were more effective than placebo. Analysis based on a small sample size showed that riociguat also had good therapeutic potential when compared with placebo. By contrast, bosentan and pomalidomide showed no significant difference compared with placebo. Regarding discontinuations for AEs, nintedanib (OR 2.09, 95 %CrI 1.20 to 3.73) and pirfenidone (3.46, 1.31 to 10.56) were associated with higher dropout rates than placebo, and the combination therapy of nintedanib+MMF did not increase the risk of AEs compared with nintedanib monotherapy. CONCLUSIONS: MMF, cyclophosphamide, rituximab, tocilizumab, nintedanib and pirfenidone are effective in the treatment of autoimmune disease-associated ILD. The efficacy of riociguat and the superiority of combination therapy need to be demonstrated in more RCTs. The tolerance of nintedanib and pirfenidone is a concern, but most of their AEs are mild and controllable.

Effects of Different Aerobic Exercises on Blood Lipid Levels in Middle-Aged and Elderly People: A Systematic Review and Bayesian Network Meta-Analysis Based on Randomized Controlled Trials.

With increasing age, dyslipidemia becomes a common health problem in the middle-aged and elderly population, posing a significant risk of cardiovascular disease. Aerobic exercise, as a non-pharmacological intervention, is considered to be effective in improving blood lipid levels, but the extent to which different types of aerobic exercise affect blood lipids is not clear. This study aims to investigate the effects of 12 different aerobic exercises on total cholesterol, triglyceride, high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol in middle-aged and elderly people aged 45 years and over through systematic review and Bayesian network Meta-analysis of randomized controlled trials. We systematically searched relevant databases and included eligible randomized controlled trials. Bayesian network meta-analysis was used to compare the effects of 12 types of aerobic exercise on lipid levels. A total of 487 randomized controlled trials involving middle-aged and elderly people over 45 years old were included. The results of the network meta-analysis showed that all types of aerobic exercise could reduce blood lipid levels compared with no intervention in middle-aged and elderly people. In terms of total cholesterol, triglyceride, and low-density lipoprotein cholesterol, swimming had the most significant effect. For HDL cholesterol, dance showed a better effect. Studies have shown that swimming and dancing have a positive effect on improving blood lipid levels in middle-aged and elderly people. It is recommended to choose the appropriate type of exercise according to personal preference and physical condition.

The Efficacy of Probiotics, Prebiotics, Synbiotics, and Fecal Microbiota Transplantation in Irritable Bowel Syndrome: A Systematic Review and Network Meta-Analysis.

Irritable bowel syndrome (IBS) is a common gastrointestinal disorder with gut microbiota imbalance playing a significant role. There are increasing numbers of research studies exploring treatment options involving probiotics, prebiotics, synbiotics, and fecal microbiota transplantation (FMT), but it is still uncertain which treatment option is superior. The research was conducted on various databases and unpublished trial data (up to February 2023). Randomized controlled trials (RCTs) were screened for adult patients with IBS comparing interventions with placebo. Probiotics, prebiotics, synbiotics, and FMT were assessed for their impact using mean difference and Bayesian network meta-analysis. Out of 6528 articles, 54 were included for probiotics, 7 for prebiotics/synbiotics, and 6 for FMT. Probiotics showed improvement in IBS symptoms, particularly with Bifidobacterium and Lactobacillus strains. Prebiotics and synbiotics did not show significant improvement. Network meta-analysis indicated the favorable effects of probiotics (OR = 0.53, 95% CI, 0.48 to 0.59) and FMT (OR = 0.46, 95% CI, 0.33 to 0.64) on IBS, with no serious adverse events reported. In short, probiotics and FMT are effective for managing IBS, with Bifidobacterium and Lactobacillus being dominant strains. However, the most effective probiotic combination or strain remains unclear, while prebiotics and synbiotics did not show significant improvement.

Which intervention is optimal to control blood glucose and improve physical performance in the elderly living with type 2 diabetes mellitus? A network meta-analysis.

BACKGROUND AND OBJECTIVES: This study aimed to find the optimal intervention available to both control blood glucose and improve physical function in the geriatric population with T2DM. METHODS AND STUDY DESIGN: A systemic review and network meta-analysis (NMA) was conducted to assess and rank the comparative efficacy of different interventions on glycosylated hemoglobin A1c (HbAc1), fasting blood glucose (FBG), muscle mass, grip strength, gait speed, lower body muscle strength, and dynamic balance. A total of eight databases were searched for eligible randomized controlled trials (RCTs) that the elderly aged more than 60 years or with mean age ≥ 55 years, the minimal duration of the RCT intervention was 6 weeks, and those lacking data about glycemic level and at least one indicator of physical performance were excluded. The Cochrane risk of bias tool was used to assess the bias of each study included. Bayesian NMA was performed as the main results, the Bayesian meta regression and the frequentist NMA as sensitivity analysis. RESULTS: Of the 2266 literature retrieved, 27 RCTs with a total of 2289 older adults were included. Health management provided by health workers exerts beneficial effects that is superior to other interventions at achieving glycemic control, but less marked improvement in physical performance. Exercise combined with cognitive training showed more pronounced improvement in muscle strength, gait speed, and dynamic balance, but ranked behind in decreasing the HbAc1 and FBG. CONCLUSIONS: Personalized health management combined with physical and cognitive training might be the optimal intervention to both accomplish glycemic control and improvement of physical performance. Further RCTs are needed to validate and assess the confidence of our results from this NMA.

Anti-PD-1/L1 antibody plus anti-VEGF antibody vs. plus VEGFR-targeted TKI as first-line therapy for unresectable hepatocellular carcinoma: a network meta-analysis.

Background: This article is based on our previous research, which was presented at the 2023 ASCO Annual Meeting I and published in Journal of Clinical Oncology as Conference Abstract (JCO. 2023;41:e16148. doi: 10.1200/JCO.2023.41.16_suppl.e16148). Both anti-programmed death 1/ligand-1 (PD-1/L1) antibody + anti-vascular endothelial growth factor (VEGF) antibody (A + A) and anti-PD-1/L1 antibody + VEGF receptor (VEGFR)-targeted tyrosine kinase inhibitor (A + T) are effective first-line therapies for unresectable hepatocellular carcinoma. However, there lacks evidence from head-to-head comparisons between these two treatments. We conducted a network meta-analysis on the efficacy and safety of them. Methods: After a rigorous literature research, 6 phase III trials were identified for the final analysis, including IMbrave150, ORIENT-32, COSMIC-312, CARES-310, LEAP-002, and REFLECT. The experiments were classified into three groups: A + A, A + T, and intermediate reference group. The primary endpoint was overall survival (OS), and secondary endpoints included progression-free survival (PFS), objective response rate (ORR), and incidence of treatment-related adverse events (TRAEs). Hazard ratio (HR) with 95% confidence intervals (CI) for OS and PFS, odds ratio (OR) for ORR, and relative risk (RR) for all grade and grade ≥3 TRAEs were calculated. Under Bayesian framework, the meta-analysis was conducted using sorafenib as intermediate reference. Results: With the rank probability of 96%, A + A showed the greatest reduction in the risk of death, without significant difference from A + T (HR: 0.82, 95% CI: 0.65-1.04). A + T showed the greatest effect in prolonging PFS and improving ORR with the rank probability of 77%, but there were no statistical differences with A + A. A + A was safer than A + T in terms of all grade of TRAEs (RR: 0.91, 95% CI: 0.82-1.00) and particularly in those grade ≥3 (RR: 0.65, 95% CI: 0.54-0.77). Conclusions: A + A had the greatest probability of delivering the longest OS, while A + T was correlated with larger PFS benefits at the cost of a lower safety rate.

Efficacy and safety of different pharmacological interventions in the treatment of tardive dyskinesia: a systematic review and network meta-analysis.

OBJECTIVES: The aim of this study is to indirectly compare and rank the different drugs that have been studied in randomized clinical trials (RCTs) in patients with tardive dyskinesia (TD) in terms of their efficacy in ameliorating the symptoms of TD and safety. DESIGN: A network meta-analysis and a systematic review were registered prospectively on PROSPERO under the ID: CRD42023407823 and were conducted in accordance with the PRISMA-NMA guidelines. DATA SOURCES: PubMed, Scopus, The Cochrane Central Register of Controlled Trials (CENTRAL), Web of Sciences, and Clinicaltrials.gov were searched to identify relevant records. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: Any parallel randomized blinded controlled clinical trials that studied the use of any medications in treating TD and assessed the symptoms using a functional scale that has been previously validated. DATA EXTRACTION: The standardized mean difference of improvement along with the reported adverse events for each drug was extracted from each trial, and a network meta-analysis was conducted using a random-effects model. RESULTS: One thousand eight hundred seventeen patients in 33 RCTs were included in the analysis. Twenty-three different drugs were compared to placebo in terms of reduction in TD symptoms. Among these, valbenazine 80 mg (SMD = - 1.66, 95%CI = [- 2.55; - 0.78]), valbenazine 40 mg (- 1.00, [- 1.89; - 0.11]), and vitamin E (- 0.77, [- 1.45; - 0.1]) significantly reduced TD symptoms in comparison to placebo, while deutetrabenazine 36 mg (- 1.00, [- 2.12; 0.11]) and reserpine (- 0.54, [- 1.09; 0.02]) did not significantly reduce symptoms. Some serious adverse events were reported for valbenazine and deutetrabenazine, which included mainly psychiatric symptoms such as depression, worsening of schizophrenia, and suicidal ideation, while mild adverse events were reported for other drugs, and their incidence in the treatment arms was comparable to those in the placebo arm. CONCLUSIONS: Valbenazine (80 and 40 mg) and vitamin E demonstrated efficacy in treating tardive dyskinesia. However, the significant side effects of valbenazine should prompt further investigation of alternative treatment modalities.

Optimal dosage ranges of various exercise types for enhancing timed up and go performance in Parkinson's disease patients: a systematic review and Bayesian network meta-analysis.

Objective: To examine the dose-response relationship between specific types of exercise for alleviating Timed up and Go (TUG) in Parkinson's disease PD. Design: Systematic review and Bayesian network meta-analysis. Data sources: PubMed, Medline, Embase, PsycINFO, Cochrane Library, and Web of Science were searched from inception until February 5th, 2024. Study analysis: Data analysis was conducted using R software with the MBNMA package. Effect sizes of outcome indicators were expressed as mean deviation (MD) and 95% confidence intervals (95% CrI). The risk of bias in the network was evaluated independently by two reviewers using ROB2. Results: A total of 73 studies involving 3,354 PD patients. The text discusses dose-response relationships in improving TUG performance among PD patients across various exercise types. Notably, Aquatic (AQE), Mix Exercise (Mul_C), Sensory Exercise (SE), and Resistance Training (RT) demonstrate effective dose ranges, with AQE optimal at 1500 METs-min/week (MD: -8.359, 95% CI: -1.398 to -2.648), Mul_C at 1000 METs-min/week (MD: -4.551, 95% CI: -8.083 to -0.946), SE at 1200 METs-min/week (MD: -5.145, 95% CI: -9.643 to -0.472), and RT at 610 METs-min/week (MD: -2.187, 95% CI: -3.161 to -1.278), respectively. However, no effective doses are found for Aerobic Exercise (AE), Balance Gait Training (BGT), Dance, and Treadmill Training (TT). Mind-body exercise (MBE) shows promise with an effective range of 130 to 750 METs-min/week and an optimal dose of 750 METs-min/week (MD: -2.822, 95% CI: -4.604 to -0.996). According to the GRADE system, the included studies' overall quality of the evidence was identified moderate level. Conclusion: This study identifies specific exercise modalities and dosages that significantly enhance TUG performance in PD patients. AQE emerges as the most effective modality, with an optimal dosage of 1,500 METs-min/week. MBE shows significant benefits at lower dosages, catering to patients with varying exercise capacities. RT exhibits a nuanced "U-shaped" dose-response relationship, suggesting an optimal range balancing efficacy and the risk of overtraining. These findings advocate for tailored exercise programs in PD management, emphasizing personalized prescriptions to maximize outcomes.Systematic Review Registration: International Prospective Register of Systematic Reviews (PROSPERO) (CRD42024506968).

Predicting Treatment Effects from Surrogate Endpoints in Historical Trials in First-Line Metastatic Castration-Resistant Prostate Cancer.

Surrogate endpoints are becoming increasingly important in health technology assessment, where decisions are based on complex cost-effectiveness models (CEMs) that require numerous input parameters. Daniels and Hughes Surrogate Model was used to predict missing effect estimates in randomized controlled trials (RCTs) evaluating first-line treatments in metastatic castration-resistant prostate cancer (mCRPC) patients. Network meta-analyses (NMAs) were conducted to assess the comparative efficacy of these treatments. Databases were searched (inception to October 2022) using Ovid®. Several grey literature searches were also conducted (PROSPERO: CRD42021283512). Available trial data for radiographic progression-free survival (rPFS) and overall survival (OS) were used to predict the unreported effect of rPFS or OS for relevant comparator treatments. Bayesian NMAs were conducted using observed and predicted treatment effects. Effect estimates and 95% credible intervals were calculated for each comparison. Mean ranks and the probability of being best (p-best) were obtained. Twenty-five RCTs met the eligibility criteria and of these, 8 reported jointly rPFS and OS; while rPFS was predicted for 12 RCTs and 10 comparators, and OS was predicted for 5 RCTs and 6 comparators. A nonstandard dose of docetaxel (docetaxel 50 mg/m2 every 2 weeks) had the highest probability of being the most effective for rPFS (p-best: 59%) and OS (p-best: 48%), followed by talazoparib plus enzalutamide (13% and 19%, respectively). Advanced surrogate modelling techniques allowed obtaining relevant parameter and indirect estimates of previously unavailable data and may be used to populate future CEMs requiring rPFS and OS in first-line mCRPC.

Efficacy and safety of androgen receptor inhibitors for treatment of advanced prostate cancer: A systematic review and network meta-analysis.

AIMS: Androgen receptor inhibitors (ARIs) have become an effective treatment for advanced prostate cancer (PC). However, it is unknown which ARI is the most helpful and safe for men with advanced PC. Our aim is to help physicians make clinical decisions and provide medication guidelines for patients with advanced PC to avoid potential risks when using ARIs for treatment. METHODS: We systematically searched the following databases: PubMed, Embase and Cochrane Library, with a literature publication deadline of February 2023. The primary efficacy outcomes were 18-month overall survival (OS), treatment-emergent adverse events (TEAEs), hypertension and fatigue. The network meta-analysis (NMA) was performed by Stata 15.1, and Revman 5.3 was used to assess the included studies' risk of bias. RESULTS: The analysis included 26 trials with 26 263 people. The surface under the cumulative ranking curve (SUCRA) concluded that enzalutamide (86.8%) showed the best effect in prolonging the OS of patients. Flutamide led to the highest risk of TEAEs (29.9%) and AEs leading to discontinuation (12.8%). Apalutamide (13.4%) led to the highest risk of grade ≥3 TEAEs. Enzalutamide had the highest risk of hypertension (0.2%), grade ≥3 hypertension (4.5%) and fatigue (5.2%). CONCLUSIONS: This NMA indicates there is no one ARI to reach both the most effective and safe therapy aims for treating advanced PC and that there is a compromise between the efficacy and safety of ARIs in the treatment of advanced PC. Physicians should weigh the risks to safety against the anticipated benefits when prescribing these drugs to patients with PC.

Rescue Therapies for Steroid-Refractory Acute Severe Ulcerative Colitis: A Systemic Review and Network Meta-analysis.

BACKGROUND AND AIMS: Approximately 40% of patients with steroid-refractory acute severe ulcerative colitis (steroid-refractory (SR) ASUC) requires colectomies. Advanced therapies may reduce the short-term colectomy rates in patients with SR ASUC. However, comparative clinical studies evaluating the effectiveness of these rescue therapies are lacking. Therefore, we conducted a network meta-analysis to study the effectiveness of rescue therapies for SR ASUC. METHODS: Six randomized controlled trials and 15 cohort studies including 2,004 patients were analyzed. Rescue drugs included tofacitinib, infliximab with a 5 or 10 mg/kg induction dose at 0, 2, and 6 weeks (IFX and IFX10, respectively), IFX with an accelerated regimen of three 5 mg/kg induction doses timed according to clinical need (accelerated IFX), tacrolimus, cyclosporine (CyA), ustekinumab, and adalimumab. Treatments were compared with a placebo. RESULTS: Tofacitinib (odds ratio [OR]: 0.09 [95% confidence interval [CI]: 0.02-0.52]), accelerated IFX (OR: 0.16 [95% CI: 0.03-0.94]), IFX (OR: 0.2 [95% CI: 0.07-0.58]), and tacrolimus (OR: 0.24 [95% CI: 0.06-0.96]) significantly reduced the short-term colectomy rates compared with placebo. IFX10 and CyA tended to prevent colectomies. However, ustekinumab and adalimumab did not significantly affect the colectomy rates. CONCLUSION: This is the first network meta-analysis to investigate the efficacy of advanced therapies in reducing short-term colectomy rates in patients with SR ASUC. Tofacitinib, accelerated IFX, standard IFX, and tacrolimus significantly reduced the colectomy rates in SR ASUC patients compared with placebo. Thus, advanced therapies should be considered for rescue therapies in patients with SR ASUC.

Compared to exercise, the effects of exercise combined with cognitive training in people with mild cognitive impairment: a network meta-analysis.

OBJECTIVES: The study aimed to evaluate the relative effectiveness of exercise combined with cognitive training (E&CT) in improving cognitive function compared to exercise alone. METHOD: PubMed, Embase, Cochrane Central Register of Controlled Trials, SPORTDiscus, and OpenGrey were systematically searched. Additional screenings were performed by reviewing citations of relevant articles. Studies were included if they met inclusion criteria. Both pairwise and network meta-analyses were performed using a random effects model in Stata 15.0. RESULTS: Totally, 46 trials from 54 literature (n = 2846) were eligible for inclusion in the meta-analysis. The network meta-analysis indicated that exercise alone was more efficacious than E&CT in improving global cognition and multicomponent exercise exhibited the highest likelihood (SUCRA value= 89.0%) of being the most effective type. Regarding memory function, E&CT presented greater potential than exercise alone, with the interactive modality ranking first (SUCRA value = 88.4%). Multicomponent exercise was identified as the top intervention for enhancing executive function. The overall quality of the included studies was rated as moderate, and the certainty of evidence ranged from low to high. CONCLUSION: Multicomponent exercise emerged as the optimal intervention for improving global cognition and executive function. Nevertheless, for memory function, the interactive modality of E&CT demonstrated the highest probability of being the most effective choice.

Safety profile of first-line targeted therapies in elderly and/or comorbid chronic lymphocytic leukaemia patients (unfit subpopulation). A systematic review and network meta-analysis.

This systematic literature review (CRD42023393903) and a Bayesian network meta-analysis (NMA) aimed to assess the relative safety profile of first-line targeted therapies (acalabrutinib, ibrutinib, obinutuzumab, ofatumumab, pirtobrutinib, ublituximab, umbralisib, venetoclax, zanubrutinib) in chronic lymphocytic leukaemia (CLL) patients with advanced age and/or comorbidities. The NMA revealed that zanubrutinib was the safest treatment option in terms of the overall safety profile (e.g., serious adverse events [AEs] grade 1-5), followed by venetoclax-obinutuzumab, which showed an advantage in terms of AEs grade 1-5. The use of Bruton's tyrosine kinase inhibitor (BTKi) monotherapy was more favourable in terms of the risk of haematological AEs, but chemoimmunotherapy showed advantages in terms of cardiovascular, gastrointestinal, and infectious AEs. The risk of secondary cancers was similar between treatments. In conclusion, targeted therapies are associated with variable and clinically relevant AEs. The therapies appear to be safer when used as monotherapy rather than in combination with immunological agents in naïve CLL patients with advanced age and/or comorbidities.
