Results Thirty-seven features were used to establish a radiomics signature, which demonstrated better predictive performance than did the image features model constructed using tumor size and intratumoral vessels in the training and validation cohorts (p 0.05). Decision curve analysis verified that the radiomics nomogram had the best clinical utility compared with the other models. Conclusion The radiomics nomogram developed in the present study is a promising tool to predict tumor necrosis and facilitate preoperative clinical decision-making for patients with ccRCC.Background National Board of Anesthesiology (NBA) pass rate is an important and critical step in clinical residency programs. Objectives This study was designed to assess the relationship between an integrative educational intervention (IEI) and the relative annual pass rate (RAPR). RAPR is defined as ratio of NBA pass rate of Shahid Beheshti University of Medical Sciences (SBMU) to the NBA pass rate of all the anesthesiology residency programs across Iran. Methods In a descriptive-analytic retrospective study from 2012 to 2019, RAPR was calculated. IEI was implanted in the latter 4years period of this time interval includes (1) individualized mentorship for residents by faculty members; (2) monthly in-training examination (ITE) in written; and (3) periodical mocked OSCE exam. Spearman's correlation coefficient was used to assess correlation between integrative educational intervention and RAPR results. P value less than 0.05 was considered statistically significant. Results There was a statistically significant relationship between "integrative educational intervention program" and the RAPR results Spearman's correlation coefficient = 0.655 (P value = 0.039). Conclusions The IEI package of Anesthesiology Department, SBMU showed a significant relationship with improvements in successfulness for anesthesiology residents in the National Board Exam (RAPR trend). More prolonged studies could prevail further aspects of these interventions.Patients with coronavirus disease 2019 (COVID-19) predominantly present with the pulmonary symptoms such as fever, cough, and shortness of breath. We present a case of an 83 years old patient with COVID-19 who presented with only gastrointestinal symptoms without respiratory complaints. Our case raises the concern regarding our current lack of understanding of extrapulmonary manifestations of COVID-19. Given genetic homology between 2019 severe acute respiratory syndrome coronavirus (SARS-CoV) 2 and SARS-CoV, our case underscores the urgent need for further studies to understand the role of the gastrointestinal system in 2019 SARS-CoV-2 transmission and COVID-19 pathogenesis.Marketing strategies selection for the purpose of increasing the sales revenue is an essential problem that can face any marketing team. Many companies facing difficulties of identifying the best marketing strategy for certain product or service, because the marketing plan involves a large number of strategies (factors) that can affect the sales revenue response. n k - p Fractional Factorials Design has been used as screening experiment to identify the most important factors which have a main effect to response the (sales revenue). Then further decision-making technique has been introduced to compare the criteria of selected strategies (factors) using analytic hierarchy process technique (AHP). Basically, AHP will provides a comprehensive and rational framework for structuring decisions criterial to each main factor where it provides the best factor or marketing strategy that can increase the sales revenue for the company. In which, the suggested methodology aims to enable decision maker the following•The opportunity to investigate a large number of marketing strategies with minimum experiments run and to enable the decision maker to identify which strategies have significant effect on response.•Select the best marketing strategy that maximize the targeted response (sales revenue).Selective androgen receptor modulators (SARMs) represent non-steroidal agents commonly abused in human and animal (i.e. equine, canine) sports, with potential for further misuse as growth promoting agents in livestock-based farming. As a direct response to the real and possible implications of illicit application in both sport as well as food production systems, this study incorporated enzymatic hydrolysis (β-glucuronidase/arylsulfatase) into a previously established protocol while maintaining the minimal volume (200 µL) of urine sample required to detect SARMs encompassing various pharmacophores in urine from a range of species (i.e. equine, bovine, human, canine and rodent). The newly presented semi-quantitative UHPLC-MS/MS-based assay is shown to be fit-for-purpose, being rapid and offering high-throughput, with validation findings fulfilling criteria stipulated within relevant doping and food control legislation.•CCβ values determined at 1 ng mL-1 for majority of analytes.•Deconjugation step included in the method led to significantly increased relative abundance of ostarine in analysed incurred urine samples demonstrating the requirement for hydrolysis to detect a total form of emerging SARMs.•Assay amenable for use within routine testing to ensure fair play in animal and human sports and that animal-derived food is free from contamination with SARM residues.Objectives It is common, among clinical and non-clinical populations alike, for paranoia and anxiety to co-occur. It has been suggested that anxiety and its related appraisal styles may contribute to development of paranoia. We aimed to evaluate different aspects of risk perception in relation to paranoia and anxiety and to identify specific aspects that may differentiate paranoia from anxiety. This paper consists of two inter-related studies. Methods Study 1 compared 30 patients with persecutory delusions, 21 patients with generalized anxiety disorder and 52 healthy controls. Study 2 compared 30 non-clinical individuals with high levels of paranoia and anxiety, 28 individuals with high anxiety only and 36 healthy controls. Within each study, the two symptomatic groups were matched on level of anxiety. Four dimensions of risk perception (i.e. likelihood, harm, controllability, and intentionality) were compared across groups, as measured by the locally validated Risk Perception Questionnaire. Cordycepin cost Results In both studies, the paranoia and the anxiety groups reported an elevated perceived likelihood of negative events than controls respectively.
