A systematic review and meta-analysis of efficacy and safety of Romosozumab in postmenopausal osteoporosis.

The study was conducted to illustrate the effect of Romosozumab in postmenopausal osteoporosis patients. Romosozumab decreased the incidence of vertebral, nonvertebral, and clinical fractures significantly. In addition, decreased incidence of falls and increased bone mineral density at lumbar spine, total hip, and femoral neck was observed. Romosozumab is a monoclonal antibody that acts against the sclerostin pathway leading to enhanced bone formation and reduced bone resorption in patients with osteoporosis. Electronic search was performed on Medline (via PubMed), The Cochrane Central Register of Controlled Trials, and clinicaltrials.gov, till May 2020, for RCTs evaluating the effectiveness of Romosozumab in postmenopausal osteoporosis. RCTs evaluating the effect of Romosozumab on fractures and bone mineral density in postmenopausal osteoporosis patients. Meta-analysis was performed by Cochrane review manager 5 (RevMan) version 5.3. Cochrane risk of bias 2.0 tool and GRADE pro-GDT were applied for methodological quality and overall evidence quality, respectively. One hundred seventy-nine studies were screened, and 10 eligible studies were included in the analysis, with a total of 6137 patients in romosozumab group and 5732 patients in control group. Romosozumab significantly reduced the incidence of vertebral fractures [OR = 0.43 (95%CI = 0.35-0.52), High-quality evidence], nonvertebral fractures [OR = 0.78 (95%CI = 0.66-0.92), High quality], and clinical fractures [OR = 0.70 (95%CI = 0.60-0.82), High quality] at 24 months. Significant reduction in incidence risk of falls [OR = 0.87 (95%CI = 0.78-0.96), High quality] was observed with romosozumab. Bone mineral density was significantly increased in the romosozumab treated groups at lumbar spine [MD = 12.66 (95%CI = 12.66-12.67), High quality], total hip [MD = 5.69 (95%CI = 5.68 - 5.69), Moderate quality], and femoral neck [MD = 5.18 (95%CI = 5.18-5.19), Moderate quality] at 12 months. The total adverse events [RR = 0.98(95%CI = 0.96-1.01), Moderate quality] and serious adverse events [RR = 0.98(95%CI = 0.88-1.08), Moderate quality] with romosozumab were comparable to the control group. The current analysis with evidence on efficacy and safety of Romosozumab, authors opine to recommend the use of Romosozumab treatment for post-menopausal osteoporosis.Systematic review registration: PROSPERO registration number: CRD42019112196.

Efficacy and safety of phenol-based partial matricectomy in treatment of onychocryptosis: A systematic review and meta-analysis.

Chemical matricectomy is an established treatment modality of onychocryptosis. In this meta-analysis, we studied the efficacy and safety profile of phenol-based matricectomy. We performed an electronic database search of PubMed, EMBASE and grey literature using the search terms '(onychocryptosis OR ingrown toe nail) AND (phenol OR chemical matricectomy)' from inception till 31-12-2020, for controlled clinical trials with phenol in one of the treatment arms and at least 10 participants in each arm. From the initial search of 335, eighteen articles were included in the final analysis. There were a total of 1655 patients, of which 856 received phenol as an intervention modality. We found that nail matrix phenolisation was associated with a 49 fewer number of recurrences per thousand patients compared with other modalities (OR: 0.28-0.57, CI 95%). It also had a reduction in 175 cases of discharge or haemorrhage per thousand patients compared with other modalities (OR: 0.25, 95% CI: 0.14-0.45). However, we found that TCA- and NaOH-based matricectomies fared better compared with phenol in incidence of postoperative discharge and haemorrhage. Patients also experienced less pain (257 fewer number per 1000, OR: 0.52, 95% CI: 0.43-0.63). Nearly, half of the included studies had some concerns about the risk of bias. As of now, phenol matricectomy combines a low recurrence rate with favourable adverse effect profile and is the preferred modality for matricectomy in grade II and III onychocryptosis.

Gabapentin prophylaxis for postoperative nausea and vomiting in abdominal surgeries: a quantitative analysis of evidence from randomized controlled clinical trials.

INTRODUCTION: Postoperative nausea and vomiting (PONV) is frequently encountered in the surgical recovery room. Abdominal surgery is one important risk factor for increased incidence of PONV. Gabapentin, an anticonvulsant with known postoperative analgesic properties, has shown some activity against PONV. Results from clinical trials evaluating the anti-emetic efficacy of gabapentin are conflicting. The present meta-analysis was performed to examine this issue. METHODS: Seventeen randomized placebo-controlled trials reporting PONV with preoperative gabapentin administration in patients undergoing abdominal surgery were included for analysis. Outcomes evaluated were nausea, vomiting, composite PONV and the use of rescue anti-emetic medication in the postoperative period. RESULTS: The pooled relative risk (RR), estimated using the random effects model of the metafor package for R, was 0.76 (95% CI 0.58-0.98) for nausea, 0.62 (0.45-0.85) for vomiting, 0.71 (0.39-1.28) for data represented as composite PONV (possibly biased by a single study, as observed in the sensitivity analysis), and 0.6 (0.41-0.89) for rescue anti-emetic use. There was a significant RR reduction for nausea and vomiting when propofol was not used as induction and/or maintenance for anaesthesia. In the abdominal hysterectomy subgroup, there was a significant RR reduction for vomiting but not for nausea. DISCUSSION: The present analysis provides evidence supporting preoperative gabapentin as a pharmacotherapy for prevention of PONV in patients undergoing abdominal surgeries. Future studies comparing preoperative gabapentin with 5HT3 antagonists are needed to precisely define its role in PONV.
