ed death during the follow-up period. CONCLUSIONS Our study demonstrates the safety and efficacy of CA coverage in facilitating adequate distal sealing in selected patients undergoing TEVAR. Because the distal sealing length is not completely sufficient in most cases requiring CA coverage, the long-term efficacy of CA coverage during TEVAR should be determined in a large prospective study. BACKGROUND Climacturia affects up to 45% of men after radical prostatectomy (RP). Although urethral slings decrease the severity and frequency of stress incontinence after RP, their efficacy as a treatment for climacturia after RP has not been well studied. AIM The aim of this study was to assess patient-reported changes in climacturia symptoms after implantation of a urethral sling as a treatment for stress incontinence after RP. METHODS After Institutional Review Board approval, a retrospective chart review identified males aged 18-80 years who received urethral slings for stress incontinence after RP at our institution from 2012 to 2017. These patients were mailed an 11-item questionnaire asking them about climacturia symptoms before and after implantation of a urethral sling. Written informed consent was obtained from patients participating in the mailed questionnaire. OUTCOMES Respondents were asked to report on climacturia frequency and severity, bother, partner bother, and incontinence before and afterhis percentage dropped to 53% after sling (P = .031). CLINICAL IMPLICATIONS Urethral slings should be discussed as a treatment strategy for climacturia during clinical consultations with patients. STRENGTHS & LIMITATIONS Strengths include consistent surgical technique. Limitations include retrospective design, lack of a nonsling comparison group, subjective nature of outcome measures, possible response bias, and variability in time interval between RP and sling procedure. learn more CONCLUSION Use of urethral slings after RP is associated with improvements in climacturia symptoms, bother, and incontinence.

BACKGROUND AND AIMS The diagnosis of gastric intestinal metaplasia (GIM) is still challenging. Optical Enhancement technology (OE) may improve the detection of GIM. We compared detection of GIM with OE, acetic acid and the Sydney biopsy protocol in a surveillance population. METHODS Consecutive patients with atrophic gastritis or known GIM were prospectively included. The stomach was examined with high definition whitelight endoscopy, followed by OE or acetic acid with targeted biopsies (11 randomisation). Subsequently, five random biopsies were taken according to the updated Sydney system. RESULTS A total of 154 patients were randomized. Higher proportions of patients with GIM were detected by OE and acetic acid versus random biopsy (60.5% vs 35.5%, 67.1% vs 31.5%, respectively; P  less then  0.0001 for both comparisons). The combined use of targeted biopsies and random biopsies provides high diagnostic yields for GIM (78.9% in OE group and 83.6% in acetic acid group). In addition, the proportion of extensive GIM was significantly increased when image enhanced endoscopy was used instead of white light endoscopy (P = 0.029, P = 0.048, respectively). CONCLUSIONS OE and acetic acid showed comparable results diagnosing GIM in the study. Targeted biopsies plus random biopsies should be used complementary in high risk populations. BACKGROUND The purpose of this study is to compare the functional and radiographic results, perioperative complications, satisfaction rate, and mid-term survivorship after unicompartmental knee arthroplasty (UKA) and total knee arthroplasty (TKA) for the treatment of lateral compartmental knee osteoarthritis (LCKO). METHODS Between March 2007 and September 2017, we identified 35 patients with primary TKAs and 121 patients with lateral UKAs (LUKAs) for LCKO with a minimum follow-up of 2 years (mean 5.3 years, range 2-12.4). The matched variables were age, gender, operation side, body mass index, American Society of Anesthesiologist grade, initial diagnosis, osteoarthritis grade in lateral compartment, and follow-up time. All patients were assessed using the Oxford Knee Score, Hospital for Special Surgery score, range of motion, length of hospital stay, satisfaction, and complications. Survivorship of UKA and TKA implants was also compared. RESULTS At last follow-up, LUKA had a significantly better postoperative Oxford Knee Score, Hospital for Special Surgery score, range of motion, shorter length of hospital time, and higher satisfaction rate than matched TKA group. There were significant differences regarding patellar tendon injury (P = .043), superficial wound infection (P = .028), patellar snapping or impingement (P = .047), and stiffness (P less then .001). Five-year survivorships free from revision were similar in both groups (99.2% vs 97.1%, P = .347). CONCLUSION LUKA for LCKO demonstrated more favorable 5-year results in comparison with TKA. Furthermore, LUKA achieved comparable mid-term survivorship and was less likely to suffer from wound infection and knee stiffness, although not overall surgical complications. BACKGROUND Failure to achieve clinically significant outcome (CSO) improvement after total hip arthroplasty (THA) imposes a potential cost-to-risk imbalance in the context of bundle payment models. Patient perception of their health state is one component of such risk. The purpose of the current study is to develop machine learning algorithms to predict CSO for the patient-reported health state (PRHS) and build a clinical decision-making tool based on risk factors. METHODS A retrospective review of primary THA patients between 2014 and 2017 was performed. Variables considered for prediction included demographics, medical history, preoperative PRHS, and modified Harris Hip Score. The minimal clinically important difference (MCID) for the PRHS was calculated using a distribution-based method. Five supervised machine learning algorithms were developed and assessed by discrimination, calibration, Brier score, and decision curve analysis. RESULTS Of 616 patients, a total of 407 (69.2%) achieved the MCID for the PRHS.
