Abstract Background Recent studies regarding the effects of erythropoietin (EPO) for treating traumatic brain injury (TBI) have been inconsistent. This study conducts a meta-analysis of randomized controlled trials (RCTs) to assess the safety and efficacy of EPO for TBI patients at various follow-up time points. Methods A literature search was performed using PubMed, Web of Science, MEDLINE, Embase, Google Scholar and the Cochrane Library for RCTs studying EPO in TBI patients published through March 2019. Non-English manuscripts and non-human studies were excluded. The assessed outcomes include mortality, neurological recovery and associated adverse effects. Dichotomous variables are presented as risk ratios (RR) with a 95% confidence interval (CI). Results A total of seven RCTs involving 1197 TBI patients were included in this study. Compared to the placebo arm, treatment with EPO did not improve acute hospital mortality or short-term mortality. However, there was a significant improvement in mid-term (6 months) follow-up survival rates. EPO administration was not associated with neurological function improvement. Regarding adverse effects, EPO treatment did not increase the incidence of thromboembolic events or other associated adverse events.Conclusions This meta-analysis indicates a slight mortality benefit for TBI patients treated with EPO at mid-term follow-up. EPO does not improve in-hospital mortality, nor does it increase adverse events including thrombotic, cardiovascular and other associated complications. Our analysis did not demonstrate a significant beneficial effect of EPO intervention on the recovery of neurological function. Future RCTs are required to further characterize the use of EPO in TBI.

Background: Prostate cancer (PCa) is the sixth primary cause of cancer death. However, conflicts are present about the efficacy and safety of Non-steroidal anti-androgens (NSAA) for its treatment. The aim of this study was to assess the efficacy and safety of NSAAs versus any comparator for the treatment of advanced or metastatic PCa (mPCa). Methodology: MEDLINE and the Cochrane Library were searched. References of included studies and clinicaltrials.gov were also searched for relevant studies. Only English language studies after 1990 were considered for review. Randomized controlled trials (RCTs) examining the efficacy and safety of NSAAs as compared with any other comparator including surgery or chemotherapy in mPCa patients were included. The outcomes include efficacy, safety and the tolerability of the treatment. The Cochrane Risk of Bias Assessment Tool was used for quality assessment. Two authors were independently involved in the selection, extraction and quality assessment of included studies and disagreements were resolved by discussion or by consulting a third reviewer. Results: Fifty-eight out of 1307 non-duplicate RCTs with 29154 patients were considered for the review. NSAA showed significantly better progression-free survival [PFS] (Hazard ratio [HR], 0.60; 95% confidence interval [CI], 0.46-0.78; P=0.0001), time to distant metastasis or death [TTD] (HR, 0.80; 95% CI 0.73-0.91; p<0.0001), objective response (Odds ratio [OR], 1.64; 95% CI 1.06-2.54; P=0.03) and clinical benefits (OR, 1.33; 95% CI 1.08-1.63; P=0.006) as compared to the control group. There was no significant difference observed between the groups in terms of overall survival (HR, 0.95; 95%CI, 0.87-1.03; P=0.18) and time to progression (HR, 0.93; 95% CI 0.77-1.11; P=0.43). Treatment-related adverse events were more with the NSAA group, but the discontinuation due to lack of efficacy reason was 43% significantly lesser than the control group in patients with mPCa. Rest of the outcomes were appeared to be non-significant. Conclusion: Treatment with NSAA was appeared to be better efficacious with respect to PFS, TTD, and response rate with considerable adverse events when compared to the control group in patients with metastatic PCa.

Teriparatide Treatment

Objective: The objective of this meta-analysis was to compare the efficacy and safety of teriparatide versus salmon calcitonin for the treatment of osteoporosis in Asian patients and to investigate whether the results of global studies could be applicable to Asian patients. Methods: PubMed, OVID, Cochrane Central Register of Controlled Trials (CENTRAL) and EMBASE up to December 2018 were searched. Eligible randomized controlled trials (RCTs) that compared teriparatide versus salmon calcitonin in Asian osteoporosis popula-tion were included. Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were used for data synthe-sis, and Cochrane Collaboration software Review Manager 5.3 was used to analyze the pooled data. Results: Three RCTs involving 529 patients were included (mean age 68.7 yr; 93.4% females; mean follow-up 6 months); outcome measures included bone mineral density (BMD) of the femoral neck, total hip and lumbar spine; bone markers and adverse events. We found that the period of 6-months of teriparatide treatment was helpful for the improvement of the BMD of lumbar vertebra, however, the improvement of BMD was not significant in femoral neck and total hip join. There was a positive correlation between bone-specific alka-line phosphatase (BSAP) and osteocalcin (OCN) and the response of Asian patients to subcutaneous injection of 20 micrograms per day of teriparatide. And the proportion of the occurrence of adverse effect was more obvious in teriparatide group compared with salmon calciton-in, but there was no significant difference. Conclusion: Results suggested that the use of teriparatide could improve the lumbar BMD by short-term (six months) application in Asian osteoporosis patients, which is beneficial to the patients who cannot tolerate adverse events of long-term treatment. The BSAP and OCN bone markers could be useful to monitor the responses of Asian osteoporosis patients to teriparatide treatment. Finally, both of teriparatide and salmon calcitonin were well tolerated by Asian patients.

Purpose: To compare all-cause mortality and primary patency with drug-coated balloon angioplasty (DCBA) compared with plain balloon angioplasty (PBA) in people with hemodialysis-related stenosis. Materials and methods: PubMed, Embase, and Cochrane Library databases were searched from November 1966 to February 2021 to identify randomized controlled trials (RCTs) that assessed the use of DCBA versus PBA for stenosis in hemodialysis circuits. Data extracted from the articles were integrated to determine all-cause mortality, target lesion primary patency (TLPP), circuit access primary patency (CAPP), 30-day adverse events, and technical success for the two approaches. We performed meta-analysis on these results using a fixed-effects model to evaluate odds ratios (ORs) and 95% confidence intervals (CIs) where I2 < 50% in a test for heterogeneity, or a random-effect model if otherwise. Sensitivity and subgroup analyses were also performed. Results: Sixteen RCTs of 1672 individuals were included in our meta-analysis, of which 839 individuals received DCBA and 833 received PBA. The pooled outcome showed no statistical difference between DCBA and PBA in all-cause mortality at 6 months (OR = 1.29, 95% CI = 0.72–2.32, p = 0.39, I2 = 4%), 12 months (OR = 1.02, 95% CI = 0.68–1.53, p = 0.91, I2 = 0%), and 24 months (OR = 1.50, 95% CI = 0.87–2.57, p = 0.15, I2 = 0%), 30-day adverse events (OR = 1.09, 95% CI = 0.30–3.98, p = 0.90, I2 = 66%), and technical success (OR = 0.18, 95% CI = 0.02–1.92, p = 0.16, I2 = 65%). The DCBA had significantly better outcomes versus PBA in TLPP at 6 months (OR = 2.37, 95% CI = 1.84–3.04, p < 0.001, I2 = 44%) and 12 months (OR = 1.77, 95% CI = 1.22–2.56, p = 0.002, I2 = 56%), and CAPP at 6 months (OR = 2.07, 95% CI = 1.21–3.54, p = 0.008, I2 = 67%) and 12 months (OR = 1.66, 95% CI = 1.29–2.15, p < 0.001, I2 = 0%). Conclusion: In hemodialysis circuit stenosis, DCBA appears to have similar safety but greater efficacy than PBA.

Modest Weight Loss

Abstract Background Weight gain and obesity are common problems encountered by patients with schizophrenia. This is partially attributable to use of second-generation antipsychotics that are associated with weight gain and other metabolic disturbances. The significance of this prevalence and its impact on premature mortality and morbidity requires better consensus on its management. The objective of this review is to determine the effects of adjunctive pharmacological interventions aimed at reducing weight gain in schizophrenia. Methods We searched the Cochrane Schizophrenia Group’s Trials Register which is based on regular searches of CINAHL, BIOSIS, AMED, EMBASE, PubMed, MEDLINE, PsycINFO, and registries of clinical trials. Inclusion criteria consisted of all randomized controlled trials examining any adjunctive pharmacological intervention for weight loss in patients with schizophrenia or schizophrenia-like illnesses. The primary outcome of each study had to be body weight or a weight related measure. We reliably selected, quality assessed, and extracted data from studies. As endpoint and change data was combined in the analysis, mean differences (MD) of the change from baseline were calculated using Review Manager 5.3. Results Sixty-one randomized controlled trials met inclusion criteria for this review (pooled n = 3328). Metformin is effective in bringing about modest weight loss (Weight: MD -3.40 kg, 95% CI -4.63 to -2.16; participants = 731; studies = 12; BMI: MD -1.39, 95% CI -1.94 to -0.85; participants = 879; studies = 13). Heterogeneity was reduced by dividing populations into first episode psychosis (FEP) and chronic populations, where FEP patients appeared to benefit most from early metformin intervention (Weight: MD -5.18 kg, 95% CI -6.22 to -4.14; BMI: MD -1.87 kg/m2, 95% CI -2.19 to -1.56; participants = 214; studies = 3) as compared to chronic patients (Weight: MD -2.22 kg, 95% CI -3.07 to -1.37; participants = 517; studies = 9; BMI: MD -1.18 kg/m2, 95% CI -1.89 to -0.48; participants = 665; studies = 10). However, ethnicity could be a confounder for the apparent effect of illness stage, as all first episode metformin intervention studies were conducted in patients with Chinese ethnicity. Metformin as a treatment for weight gain may be associated with additional adaptive changes in fasting insulin levels and insulin resistance. The frequency of adverse effects did not differ between metformin and placebo groups. Moreover, glucagon-like peptide agonists (GLP-1RAs), such as liraglutide and exenatide, were also effective in reducing weight (Weight: MD -3.95 kg, 95% CI -7.08 to -0.83; participants = 165; studies = 3; BMI -1.26 kg/m2, 95% CI -2.21 to -0.30; participants = 165; studies = 3; waist circumference: MD -3.25, 95% CI -5.93 to -0.57; participants = 165, studies = 3). The frequency of adverse effects did not differ between GLP-1RA and placebo groups. Topiramate 200 mg was also effective for weight reduction (Weight: MD=-6.61 kg, 95% CI -9.62 to -3.61; BMI: MD=-2.72, 95% CI -3.25 to -2.20; participants = 181, studies = 3). Discussion This review highlights the promise of pharmacological interventions for decreasing weight gain associated with antipsychotic use. Of the drugs studied, metformin has the most evidence and was most effective in bringing about modest weight loss. Topiramate and GLP-1RA also have accumulating evidence supporting efficacy in reducing weight. Interpretation for other agents is limited by the small number of studies, sample size, and short study duration. Future studies that are adequately powered, with longer treatment duration, will be needed in evaluating the efficacy and safety of interventions for managing weight gain further.

Background. Patients with psoriasis need long-term medication to control their condition. Recent studies suggest that changing the intestinal flora may be a potential treatment. Methods. The databases were utilized to search the randomized controlled trials (RCTs) and preclinical trials about probiotic supplement in the treatment of psoriasis. The retrieval time is from the establishment of these databases to December 2020. RevMan5.3 was used for the risk assessment of bias and meta-analysis. This systematic review was registered in PROSPERO (CRD42021232756). Results. A total of 3 RCTs involving 164 participants were included. Two RCTs showed that probiotics can improve PASI and thereby improve the condition. For inflammation-related indicators, only one RCT showed that probiotics can improve the levels of CRP and TNF-α but have no obvious improvement effect on IL6. One RCT demonstrated the total effective rate of probiotics in the treatment of psoriasis. For adverse events, one RCT showed that the incidence of adverse events of probiotic treatment was low. Preclinical studies showed that continuous intervention with oral probiotics can significantly improve the progression of psoriasis and reduce the expression of inflammatory factors. The meta-analysis showed that the PASI between two groups was of no statistical significance (SMD 1.83 [-0.41, 4.07], P = 0.11 ). Meanwhile, probiotics may improve skin thickness (SMD -5.87 [-11.34, -0.41], P = 0.04 ) in animal model. Conclusion. Prebiotics may have a positive effect on alleviating the clinical symptoms of psoriasis, but a large sample of RCTs is still needed to support its therapeutic effect in psoriasis.

Abstract Background: Several studies have investigated the effects of intrathecal magnesium sulfate as an adjuvant for bupivacaine; however, their conclusions are inconsistent. Therefore, it is necessary to conduct a meta-analysis on this topic.Methods We searched Pubmed, EMBASE (OvidSP) and Cochrane Central Register of Controlled Trials (CENTRAL) for randomized controlled trials (RCTs) comparing the effect of intrathecal bupivacaine combined with magnesium sulfate versus bupivacaine alone in adults using spinal anesthesia.Results Eighteen studies that met our inclusion criteria were included in our analysis. We found that the addition of intrathecal magnesium sulfate to bupivacaine provided a longer duration of analgesia (SMD 0.99; 95% CI [0.45, 1.52], P = 0.0003, I2 = 93%), prolonged the duration of sensory block (MD=106.69; 95% CI, 60.93-152.45; P<0.00001), delayed the onset of sensory block (SMD 1.20; 95% CI [0.65, 1.75], P =<0.0001, I2 = 91%) and motor block (SMD 1.46; 95% CI [0.23, 2.69], P =0.02, I2 = 96%), decreased the requirement for rescue analgesia (SMD -0.81; 95% CI [-1.06, -0.56], P < 0.00001, I2 = 11%). For duration of motor block, and incidence of postoperative adverse events (such as nausea and vomiting, hypotension, bradycardia, pruritus, shivering and neurological deficit), no statistically differences were observed between the 2 groups.Conclusions Our meta-analysis demonstrated that intrathecal magnesium sulfate combined with bupivacaine prolongs the dusration of analgesia, without an impact on the adverse events. However, the quality of evidence was very low when using GRADE to assess it. Given adverse effects before use, more high-quality trials with large samples are required before magnesium sulfate is routinely used as a intrathecal adjunct.
