Introduction Cumulative network meta-analysis (NMA) is a method to provide a global comparison of multiple treatments with real-time update to evidence users. Several studies investigated the ranking of cumulative NMA and the recommendations of practice guidelines. However, to the best of our knowledge, no study has evaluated the cumulative NMA ranking and prescription patterns. Here, we present a protocol for a meta-epidemiological investigation to compare the results of cumulative NMA with the recommendations in postmenopausal osteoporosis practice guidelines and with the actual prescriptions. Method and analysis We will use the data of primary trials from the upcoming postmenopausal osteoporosis clinical practice guideline of the Endocrine Society. We will conduct cumulative NMA using all eligible trials and generate hierarchy of treatment rankings by using the surface under the cumulative ranking curve. We will search practice guidelines in relevant society websites. Two review authors will extract the practice recommendations. We will use data from the Medical Expenditures Panel Survey, a US representative sample of the non-institutionalised population, to determine the prescription patterns. Ethics and dissemination Because all data will be retrieved from public databases, institutional review board approval is not required. We will publish our findings in a peer-reviewed journal and present key findings at conferences. Trial registration number UMIN000031894: Pre-results.

OBJECTIVETranspsoas lateral interbody fusion is one of the lateral minimally invasive approaches for lumbar spine surgery. Most surgeons insert the interbody cage laterally and then insert pedicle or cortical screw and rod instrumentation posteriorly. However, standalone cages have also been used to avoid posterior instrumentation. To the best of the authors’ knowledge, the literature on comparison of the two approaches is sparse.METHODSThe authors performed a systematic review and meta-analysis of the available literature on transpsoas lateral interbody fusion by an electronic search of the PubMed, EMBASE, and Scopus databases using PRISMA guidelines. They compared patients undergoing transpsoas standalone fusion (TP) with those undergoing transpsoas fusion with posterior instrumentation (TPP).RESULTSA total of 28 studies with 1462 patients were included. Three hundred and seventy-four patients underwent TPP, and 956 patients underwent TP. The mean patient age ranged from 45.7 to 68 years in the TP group, and 50 to 67.7 years in the TPP group. The incidence of reoperation was found to be higher for TP (0.08, 95% confidence interval [CI] 0.04–0.11) compared to TPP (0.03, 95% CI 0.01–0.06; p = 0.057). Similarly, the incidence of cage movement was found to be greater in TP (0.18, 95% CI 0.10–0.26) compared to TPP (0.03, 95% CI 0.00–0.05; p < 0.001). Oswestry Disability Index (ODI) and visual analog scale (VAS) scores and postoperative transient deficits were found to be comparable between the two groups.CONCLUSIONSThese results appear to suggest that addition of posterior instrumentation to transpsoas fusion is associated with decreased reoperations and cage movements. The results of previous systematic reviews and meta-analyses should be reevaluated in light of these results, which seem to suggest that higher reoperation and subsidence rates may be due to the use of the standalone technique.

This systematic review and meta‐analysis sought to summarize the available evidence on the use of transcatheter aortic valve replacement (TAVR) in patients with Native Aortic Valve Regurgitation (NAVR) and compare outcomes between first and second generation valves. Owing to the improvements in transcatheter heart valve design and procedural success, TAVR has become increasingly performed in broader aortic valve pathologies. We searched Medline, Embase, Cochrane, and Scopus databases from 2007 to 2018 and performed a systematic review on reports with at least 10 patients with aortic valve regurgitation undergoing TAVR procedure. The main outcome of interest was all‐cause mortality at 30 days. A total of 638 patients across 12 studies were included. Mean age ranged from 68 to 84. Society of Thoracic Surgeons score ranged from 5.4% to 13.1% and Logistic EuroSCORE ranged from 18.2% to 33%. The incidence rate of all‐cause mortality at 30 days was found to be 11% (95% CI 7%‐16%; I2 = 20.86%). All‐cause mortality at 30 days for first generation valves had an incidence rate of 15% (95% CI 10%‐20%; I2 = 10%) compared to 7% (95% CI 3%‐13%; I2 = 37%) in second generation valves with subgroup interaction analysis P = 0.059. Device success incidence rate in second generation valves was 92% (95% CI 83%‐99%; I2 = 67%) vs 68% (95% CI 59%‐77%; I2 = 53%) in first generation valves with P = 0.001. TAVR appears to be a feasible treatment choice for NAVR patients at high risk for surgical valve replacement. Second generation valves show promising results in terms of short‐term outcomes.

Abstract Background Females with congenital adrenal hyperplasia (CAH) and atypical genitalia often undergo complex surgeries; however, their outcomes remain largely uncertain. Methods We searched several databases through 8 March 2016 for studies evaluating genital reconstructive surgery in females with CAH. Reviewers working independently and in duplicate selected and appraised the studies. Results We included 29 observational studies (1178 patients, mean age at surgery, 2.7 ± 4.7 years; mostly classic CAH). After an average follow-up of 10.3 years, most patients who had undergone surgery had a female gender identity (88.7%) and were heterosexual (76.2%). Females who underwent surgery reported a sexual function score of 25.13 using the Female Sexual Function Index (maximum score, 36). Many patients continued to complain of substantial impairment of sensitivity in the clitoris, vaginal penetration difficulties, and low intercourse frequency. Most patients were sexually active, although only 48% reported comfortable intercourse. Most patients (79.4%) and treating health care professionals (71.8%) were satisfied with the surgical outcomes. Vaginal stenosis was common (27%), and other surgical complications, such as fistulas, urinary incontinence, and urinary tract infections, were less common. Data on quality of life were sparse and inconclusive. Conclusion The long-term follow-up of females with CAH who had undergone urogenital reconstructive surgery shows variable sexual function. Most patients were sexually active and satisfied with the surgical outcomes; however, some patients still complained of impairment in sexual experience and satisfaction. The certainty in the available evidence is very low.

Background Data about anticoagulation in pulmonary arterial hypertension (PAH) patients are inconsistent. The objective of this study was to examine the impact of adjunctive oral anticoagulants in patients with PAH through meta-analysis, and to further assess whether response differs by PAH subtype. Methods and Results Cochrane CENTRAL, Medline, and Scopus databases were searched for randomized or nonrandomized studies that assessed the association between anticoagulation and outcomes in patients with PAH. Hazard ratios (HRs) for mortality were pooled using the random effects model. Subgroup analyses were performed for type of PAH and study design. Twelve nonrandomized studies, at moderate risk of bias, were included. These consisted of 2512 patients (1342 receiving anticoagulation and 1170 controls). Anticoagulation significantly reduced mortality in the overall PAH cohort (HR, 0.73 [0.57, 0.93]; P =0.001; I 2 =64%). On subgroup analysis, a significant mortality reduction was seen in idiopathic PAH patients (HR, 0.73 [0.56, 0.95]; P =0.02; I 2 =46%), whereas no significant difference was observed in connective tissue disease–related PAH (HR, 1.16 [0.58, 2.32]; P =0.67; I 2 =71%). Sensitivity analysis specific to scleroderma-associated PAH demonstrated a significant increase in mortality with anticoagulant use (HR, 1.58 [1.08, 2.31]; P =0.02; I 2 =9%). Conclusions This meta-analysis shows that use of anticoagulation may improve survival in idiopathic PAH patients, while increasing mortality when used in scleroderma-associated-PAH patients. Currently, no randomized clinical trials have been published, and until randomized data are available, anticoagulant use in PAH should be tailored to PAH subtype.

We aimed to develop tools that can facilitate uptake of evidence summarised in systematic reviews by clinical decision makers in health systems. After conducting a systematic review on the management of anxiety in children, we interviewed health system representatives, clinicians and patients to ask about additional information needed for decision-making. Using stakeholders’ feedback and literature searches for contextual and implementation information, we developed two tools (decision aids (DAs)), one for the health system and the second for the clinical encounter. This information mapped to factors of the GRADE (Grading of Recommendations, Assessment, Development and Evaluation) Evidence to Decision Framework. The health system DAs provided information on which patients are candidate for treatment, values and preferences, costs and resources, acceptability, impact on health equity, feasibility, drug dosing, alternative therapies, remission rates and prognosis. Health system stakeholders found the DA useful for clinical decision-making and generalisable to other conditions. The encounter DA was produced as cards containing information on issues that drive treatment decisions (effect on symptoms, effect on function, treatment burden, side effects and cost). Patients and parents prioritised the cards and chose the order in which these issues were discussed with clinician. The encounter DA was found to be helpful by patients, parents and clinicians. We conclude that the uptake of evidence summaries by health systems can be enhanced by developing tools that provide contextual and implementation information about clinical care. A dual approach addressing health system stakeholders as well as clinicians and patients is likely feasible and helpful.
