Construction and internal validation of a nomogram for predicting the risk of positive prostate biopsy in MRI-negative patients / 现代泌尿外科杂志

【Objective】 To establish a nomogram model for predicting the risk of positive prostate biopsy in MRI-negative patients, and to perform the internal validation. 【Methods】 We retrospectively analyzed the clinical data of 197 MRI-negative patients who underwent prostate biopsy at our hospital, analyzed the independent predictors of positive prostate biopsy with univariate and multivariate logistic regression analysis, constructed the nomogram model and conducted internal validation. 【Results】 Multivariate logistic regression analysis showed age (P=0.003), digital rectal examination (DRE)(P=0.005), total prostate-specific antigen (tPSA) (P=0.001) and prostate volume (PV)(P<0.001) were independent risk factors of MRI-negative but prostate biopsy-positive results. The nomogram model based on all variables was established. The area under the receiver operating characteristic (ROC) curve (AUC) was 0.862, which was greater than that of tPSA (AUC=0.739), PV(AUC=0.711) and DRE(AUC=0.666) (all P<0.05). The average absolute error of the model was 1.1% after 500 internal resampling, indicating that the prediction of positive prostate biopsy was consistent with the actual situation. 【Conclusion】 The age, DRE, tPSA and PV were independent predictors of positive prostate biopsy in MRI-negative patients. The nomogram model has a good prediction performance.

Clinical and counseling psychology graduate students' cognition and attitudes of psychometric ethics / 中国心理卫生杂志

Objective:To learn the cognition and attitudes of psychometric ethics of graduate students whose major was clinical psychology or counseling psychology,and to investigate whether ethics training could influence their cognition and attitude.Methods:Researchers distributed the questionnaire online regarding cognition and attitudes of psychometric ethics among clinical and counseling psychology graduate students.Seventy-six feedbacks were collected (4 students were learning ethics courses,27 students had learned ethics courses,45 students hadnt learned ethics courses).The questionnaire included the Psychometric Cognition Questionnaire (PCQ),Situational Judgement Questionnaire (SJQ) and Psychometric Attitude Questionnaire (PAQ).The first two sets of questionnaires reflected ethics knowledge.The last one showed ethics attitudes and behavioral tendencies.Results:The correct rates in participants who had learned or were learning ethics were 76.5％ and 75.1％ at the first and second set of questionnaires,while were 73.9％ and 74.2％ in other participants.The correct rates of three major clauses in PCQ were 90.3％,67.7％ and 74.2％,significantly higher than participants who never learned ethics,whose correct rates were 88.9％,66.7％,and 44.4％ (Ps ＜ 0.05).There were no significant differences in SJQ between those who had learned or was learning ethics and those who had never learned ethics (Ps ＞0.05).Participants who had learned or were leaning ethics scored in sum in PAQ that had no significant differences with those who had never learned ethics(Ps ＞ 0.05).Conclusion:Clinical and counseling psychology graduate students master considerable level of knowledge on ethics and attitude.Ethics training is essential for acquiring psychometric ethics.
