Prostate Needle Biopsy

Digital pathology systems (DPSs) have been globally implemented, and computer-assisted diagnosis (CAD) software has been actively developed in recent years. This study aimed to investigate perceptions of digital pathology and the demand for CAD. An online survey involving members of the Korean Society of Pathologists was conducted, and a demonstration clip of the diagnostic assistant software for a prostate needle biopsy was shown to them to provide a simple experience with CAD. One hundred sixty-four Korean pathologists (13.6% of 1210 Korean pathologists) participated. The majority (77.4%) answered affirmatively regarding the necessity of implementing a DPS, and 26.8% had plans to implement or increase the use of DPSs in the following 2–3 years at their medical institutions. Pathologists felt that multidisciplinary care or conference accessibility (56.7%), remote consultation (49.4%), and big data building (32.9%) were useful parts of DPSs. Most pathologists (81.7%) responded that CAD software would assist with the diagnostic process. In a prostate needle biopsy, pathologists used the software to improve the measurement of tumor volume and/or length and core length but not to suggest a diagnostic name or Gleason grade. Korean pathologists who participated in the survey had highly positive perceptions of digital pathology and maintained a positive attitude toward the use of CAD software.

Abstract Background: Artificial intelligence (AI) is rapidly gaining attention in medicine and in pathology in particular. While much progress has been made in refining the accuracy of algorithms, thereby increasing their potential use, we need to better understand how these algorithms will be used by pathologists, who will remain for the foreseeable future the decision-makers. The objective of this paper is to determine the propensity of pathologists to rely on AI decision aids and to investigate whether providing information on the algorithm impacts this reliance.Methods: To test our hypotheses, we conducted an experiment with within-subjects design using an online survey study. 116 respondent pathologists and pathology students participated in the experiment. Each participant was tasked with assessing the Gleason grade for a series of 12 prostate cancer samples under three conditions: without advice, with advice from an AI decision aid, and with advice from an AI decision aid with information provided on the algorithm, namely the algorithm accuracy rate and the algorithm model. Scores were computed by comparing the respondents’ scores with the “true” score at the individual-question level. A mixed effects logistic regression was used to analyze the difference in scores between the different conditions, controlling for the random effects of participants and images and to assess the interactions with Experience, Gender and beliefs towards AI.Results: Participant responses to the questions with AI decision aids were significantly more accurate than the control condition without aid. However, no significant difference was found when subjects were provided with additional accuracy rate and model information on the AI advice. Moreover, the propensity to rely on AI was found to relate to general beliefs on AI but not with particular assessments of the AI tool offered. Males also performed better in the No-aid condition but not in the AI-aid condition.Conclusions: AI can significantly influence pathologists and the general beliefs in AI could be major predictors of future reliance on AI by pathologists.

125 Background: Reports have suggested that African Americans (AA) with prostate cancer (PCa) have both increased incidence and increased aggressiveness of tumors located in the transition zone (TZ). Our goal was to evaluate the utility of TZ−directed prostate biopsies in a predominantly AA population at a Veterans Affairs Hospital. Methods: After obtaining IRB approval, we retrospectively reviewed all patients with PCa found on a 14 core biopsy in which 12 needle biopsies were directed at the peripheral zone (PZ) and 2 at the TZ, between January 2010 and June 2014. Location of disease was determined by the results of the biopsy, either PZ alone, TZ alone or both. Aggressiveness of disease was defined by Gleason grade, percent involvement of PCa in any core and NCCN risk-stratification. Self−identified race was recorded for all patients. A series of Mann Whitney U and Chi−square tests were used to compare variables. Results: The total patient cohort consisted of 398 men, in which 277 (70%) were AA. When compared with Caucasian Americans (CA), AA patients had more NCCN intermediate or high risk (50% vs 39%, p = 0.25) PCa. Most patients had PCa limited to the PZ only (n=190) or in both the PZ and TZ (n=191). For 17 patients (4%) PCa was limited to TZ core(s) only, 14 (5%) AA vs 3 (2%) CA (p = 0.24). Of these 17 patients, 14 (82%) had Gleason 6 only disease. Patients with PCa in both the PZ and TZ had higher PSA and PSA density, greater volume of disease, higher-grade lesions and worse NCCN category (all values p <0.01) compared with patients in which the positive biopsy was limited to the PZ. Of these 191 TZ and PZ positive patients, a greater proportion were AA (n=135, 49%) compared to CA (n=56, 46%) (p = 0.48). For patients with PZ and TZ disease, the TZ had the highest-grade in 21 (11%) men, 10% AA and 13% CA (p = 0.67). For most patients (89%), PZ tumor grade was equal to or greater than TZ. Conclusions: TZ−directed prostate needle biopsy cores were rarely the sole location of PCa and when found were usually low grade without clear racial variation. Patients with PCa in both the PZ and TZ had aggressive disease regardless of race although the TZ core resulted in upgrading in a minority of patients. TZ-directed biopsies do not appear to be of greater benefit to AA than CA.

Threat perceptions towards immigrants continue to gain importance in the context of growing international migration. To reduce associated intergroup conflicts, it is crucial to understand the personal and contextual determinants of perceived threat. In a large online survey study (N = 1,184), we investigated the effects of ideology (i.e., Right-Wing Authoritarianism and Social Dominance Orientation), subjective societal status (SSS) and their interaction effects in predicting symbolic and realistic threat perceptions towards Middle Eastern immigrants. Results showed that ideology (higher RWA and SDO) and lower SSS significantly predicted both symbolic and realistic threat, even after controlling for income, education, age, and gender. Furthermore, ideology and SSS interacted significantly in predicting realistic threat, with higher levels of SDO and RWA enhancing the effect of SSS. In the discussion, we focus on the implications of our findings with respect to understanding societal conflicts, discuss methodological limitations, and provide directions for future research.

The Impact

BACKGROUND The first nationwide lockdown due to the COVID-19 pandemic was implemented in Vietnam from April 1 to 15, 2020. Nevertheless, there has been limited information on the impact of COVID-19 on the psychological health of the public. OBJECTIVE This study aimed to estimate the prevalence of psychological issues and identify the factors associated with the psychological impact of COVID-19 during the first nationwide lockdown among the general population in Vietnam. METHODS We employed a cross-sectional study design with convenience sampling. A self-administered, online survey was used to collect data and assess psychological distress, depression, anxiety, and stress of participants from April 10 to 15, 2020. The Impact of Event Scale-Revised (IES-R) and the Depression, Anxiety, and Stress Scale-21 (DASS-21) were utilized to assess psychological distress, depression, anxiety, and stress of participants during social distancing due to COVID-19. Associations across factors were explored using regression analysis. RESULTS A total of 1385 respondents completed the survey. Of this, 35.9% (n=497) experienced psychological distress, as well as depression (n=325, 23.5%), anxiety (n=195, 14.1%), and stress (n=309, 22.3%). Respondents who evaluated their physical health as average had a higher IES-R score (beta coefficient [B]=9.16, 95% CI 6.43 to 11.89), as well as higher depression (B=5.85, 95% CI 4.49 to 7.21), anxiety (B=3.64, 95% CI 2.64 to 4.63), and stress (B=5.19, 95% CI 3.83 to 6.56) scores for DASS-21 than those who rated their health as good or very good. Those who self-reported their health as bad or very bad experienced more severe depression (B=9.57, 95% CI 4.54 to 14.59), anxiety (B=7.24, 95% CI 3.55 to 10.9), and stress (B=10.60, 95% CI 5.56 to 15.65). Unemployment was more likely to be associated with depression (B=3.34, 95% CI 1.68 to 5.01) and stress (B=2.34, 95% CI 0.84 to 3.85). Regarding worries about COVID-19, more than half (n=755, 54.5%) expressed concern for their children aged &lt;18 years, which increased their IES-R score (B=7.81, 95% CI 4.98 to 10.64) and DASS-21 stress score (B=1.75, 95% CI 0.27 to 3.24). The majority of respondents (n=1335, 96.4%) were confident about their doctor’s expertise in terms of COVID-19 diagnosis and treatment, which was positively associated with less distress caused by the outbreak (B=–7.84, 95% CI –14.58 to –1.11). CONCLUSIONS The findings highlight the effect of COVID-19 on mental health during the nationwide lockdown among the general population in Vietnam. The study provides useful evidence for policy decision makers to develop and implement interventions to mitigate these impacts. CLINICALTRIAL
