This requires effective communication of procedural risks to patients and is learned during residency. Alectinib cell line No systematic review has yet examined current risk disclosure. This systematic review aims to use existing published information to assess preoperative provision of risk information by surgeons. METHODS Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses as a guide, a standardized search in Ovid MEDLINE, Embase, CINHAL, and PubMed was performed. Three reviewers performed the study screening, with 2-reviewer consensus required at each stage. Studies containing objective information concerning preoperative risk provision in adult surgical patients were selected for inclusion. Studies exclusively addressing interventions for pediatric patients or trauma were excluded, as were studies addressing risks of anesthesia. RESULTS The initial search returned 12,988 papers after deduplication, 33 of which met inclusion criteria. These studies primarily evaluated consent through surveys of providers, record reviews and consent recordings. The most ubiquitous finding of all study types was high levels of intra-surgeon variation in what risk information is provided to patients preoperatively. Studies recording consents found the lowest rates of risk disclosure. Studies using multiple forms of investigation corroborated this, finding disparity between verbally provided information vs chart documentation. CONCLUSIONS The wide variance in what information is provided to patients preoperatively inhibits the realization of the ethical and practical components of informed consent. The findings of this review indicate that significant opportunities exist for practice improvement. Future development of surgical communication tools and techniques should emphasize standardizing what risks are shared with patients. BACKGROUND In the absence of head-to-head comparison studies, the present network meta-analysis evaluated and compared the efficacy of 4 therapeutic alternatives for refractory colorectal cancer. MATERIALS AND METHODS The search focused on results from phase III randomized controlled trials. Separate (subgroup) network meta-analyses were conducted to obtain drug comparisons stratified by various patient characteristics. The principal outcome of interest was overall survival (OS). RESULTS No difference in OS was found between regorafenib and TAS-102. For a rectal primary location, TAS-102 conferred benefit versus placebo (hazard ratio [HR], 0.671), but regorafenib did not (HR, 0.950). For patients aged > 65 years, TAS-102 showed benefit versus placebo (HR, 0.579) but regorafenib did not (HR, 0.816). For patients with an Eastern Cooperative Oncology Group (ECOG) performance status (PS) of 0 in the indirect comparison, regorafenib showed benefit versus placebo (HR, 0.687), as did TAS-102 (HR, 0.756) but with a lower advantage. For patients with RAS wild type not previously treated with anti-EGFR antibodies, panitumumab was the optimal choice for OS. CONCLUSIONS No differences in OS were found between regorafenib and TAS-102. Possible greater efficacy was found for TAS-102 compared with regorafenib for patients with a rectal primary location, ECOG PS > 0, and age > 65 years. In contrast, regorafenib showed possible greater effectiveness for patients with ECOG PS 0 and age less then 65 years. In the RAS WT population, the anti-EGFR drug showed superiority with respect to TAS-102 and regorafenib. These results should be viewed as only exploratory, and further prospective studies are warranted to validate these data. BACKGROUND Reverse shoulder arthroplasty is quickly becoming the most frequently performed glenohumeral joint replacement. The purpose of this study was to evaluate the volumetric and linear wear rates of ultrahigh-molecular-weight polyethylene humeral liners in vivo at a minimum 5-year follow-up. METHODS Radiostereometric analysis was used to image 15 patients at terminal range of motion in forward flexion, abduction, external rotation, and internal rotation and with the arm at the side. The relative position and orientation of the glenosphere and polyethylene were identified for each arm position. The apparent intersection of the glenosphere into the polyethylene was recorded as wear. Mean volumetric and linear wear rates were recorded, and Pearson correlation coefficients were applied to the 36-mm liners to assess the relationship between the wear rate and term of service. RESULTS The mean reverse shoulder arthroplasty term of service at the time of imaging was 8 ± 1 years (range, 6-11 years). The mean volumetric and linear wear rates for the 36-mm liners (n = 13) were 42 ± 22 mm3/yr (r = 0.688, P = .009) and 0.11 ± 0.03 mm/yr (r = 0.767, P = .002), respectively. The mean volumetric and linear wear rates for the 42-mm liners (n = 2) were 114 ± 44 mm3/yr and 0.17 ± 0.01 mm/yr, respectively. No single arm position was able to capture all recorded wear individually. CONCLUSION This study showed volumetric and linear wear rates of approximately 40 mm3/yr and 0.1 mm/yr, respectively, for the 36-mm polyethylene liners. The 42-mm liners showed higher wear rates, although a greater number of subjects is required for conclusive results. In vivo wear of reverse total shoulder arthroplasty is multidirectional and perceptible.

METHODS Using a national insurance database from 2007 to 2016, patients who underwent shoulder arthroplasty with an indication for postoperative therapeutic anticoagulation in the case of atrial fibrillation or acute postoperative venous thromboembolism were identified. Those with a prescription for a therapeutic anticoagulant within 2 weeks of surgery were identified and compared with controls without postoperative therapeutic anticoagulant prescriptions. Wound complications and postoperative infection at 3 and 6 months, and revision shoulder arthroplasty at 6 months and all time points were then compared in the database using a multivariable logistic regression analysis. RESULTS A total of 17,272 patients were included, including 684 patients who received therapeutic anticoagulation and 16,588 controls. Patients receiving therapeutic anticoagulation experienced increased wound complications at 3 months (odds ratio [OR] 3.
