Development and validation of a simulator-based test in transurethral resection of bladder tumours (TURBEST).

Development and validation of a simulator-based test in transurethral resection of bladder tumours (TURBEST). Scand J Urol. 2019 Sep 20;:1-6 Authors: Bube SH, Hansen RB, Dahl C, Konge L, Azawi N Abstract Objectives: A prospective observational trial to develop and gather validity evidence using Messick's framework for a simulator-based test in TURB. Methods: Forty-nine doctors were recruited from urology departments (Herlev/Gentofte University Hospital, Rigshospitalet Copenhagen University Hospital and Zealand University Hospital Roskilde) and enrolled from April to September 2018. The TURB Mentor™ virtual reality (VR) simulator was assessed at an expert meeting selecting clinically relevant cases and metrics. Test sessions were done on identical simulators at two university hospitals in Denmark. All participants performed three TURB procedures on the VR simulator. Simulator metrics were analysed with analysis of variance (ANOVA) and metrics with the ability to discriminate between groups were combined in a total simulator score. Finally, a pass/fail score was identified using the contrasting groups' method. Results: Eleven simulator metrics were found eligible and four had significant discrimination ability between competency levels: resected pathology (%) (p = 0.008); cutting in bladder wall (n) (p = 0.004); time (s) (p = 0.034); and inspection of the bladder wall (%) (p = 0.002). The interna...

Authors: Günal A, Pekçetin S, Demirtürk F, ┼×enol H, Håkansson C, Wagman P Abstract Background: Occupational balance (OB) is an important concept in occupational therapy and is considered as an essential component of health and well-being. Aim: The aim of this study was to investigate the validity and reliability of the Turkish version of the Occupational Balance Questionnaire-11 (OBQ11-T). Materials and methods: The OBQ11-T was administered to 116 individuals for construct validity analysis and to 58 individuals for reliability analysis. Validity was determined using explanatory and confirma...

Conclusion: MDCT provides good results in detecting sinus fat, venous invasion and kidney-confined tumors, but evaluation of perinephric fat remains a difficult task, leading to reduced accuracy in T3a staging. PMID: 31607203 [PubMed - as supplied by publisher]

This study was aimed to estimate the length of the MIC in the interforaminal safe zone, to analyse its course in relation to the lingual and the buccal cortical plates of the mandible using cone beam computed tomography (CBCT) scans and to relate the above findings to age, gender, dental status and Malaysian races.MethodsRetrospective analysis of 100 CBCT scans (n = 200) was performed on both sides of the mandible. Cross-sectional and panoramic images were reconstructed. The length of the MIC and the horizontal distances between the MIC and the buccal and the lingual cortical plates were measured at the three...

Background From infancy to adulthood, the mandible develops increased ramus height, prominence of the chin, and laterally widened gonial angles. In Crouzon and Apert syndromes, both relative retrognathia and prognathic jaws have been reported. Growth is influenced by a variety of factors, including the growth and relative position of the skull base, functional coordination, and the spatial influence of the laryngopharynx. Thus, this study aimed to explore in detail the evolution of the mandible in both syndromes and its relationship with the entire facial structure and skull base. Methods One hundred twenty-three preo...

In this issue, Tang et al. [1] from Taiwan report on an increasingly important issue in thoracic medicine and surgery, the natural history of small, asymptomatic lung nodules. The widespread use, over the last couple of decades, of increasingly sensitive computed tomography (CT) scans with reducing radiation dose has resulted in the recognition of a significant population of otherwise healthy patients who have a lung nodule of undefined nature. In most cases, this lung nodule has been detected at the time of a CT scan for a completely different issue —atypical chest pain, back pain, shoulder pain, and often for inves...

It is found that the isospin splitting of pion elliptic flow favors a strong vector-isovector inte...
