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.

Abstract INTRODUCTION Diffuse intrinsic pontine glioma (DIPG) is a rare and aggressive childhood brainstem malignancy with a two-year survival rate of ≤10%. In this international survey study we aim to evaluate the use of complementary and alternative medicine (CAM) in this patient population. METHODS Parents of-, and physicians treating DIPG patients were asked to participate in a retrospective online survey with questions regarding CAM use during time of illness. RESULTS 120 parents and 75 physicians contributed to the online survey between January and May 2020. Physicians estimated that <50% of their patients used CAM, whereas 69% of the parents reported to have used CAM to treat their child during time of illness. Cannabis was the most widely used form of CAM, followed by vitamins and minerals, melatonin, curcumin and boswellic acid. CAM was mainly used to actively treat the tumor. Other motivations were to treat side effects of chemotherapy, or to comfort the child. Children diagnosed ≥2016 were more likely to use CAM (χ2=6.08, p=0.014). No significant difference was found between CAM users and non-users based on ethnicity (χ2=4.18, p=0.382) and country of residence (χ2=9.37, p=0.154). Almost 50% of the physicians do not frequently ask their patients about possible CAM use. CONCLUSION This survey demonstrates that worldwide a considerable number of DIPG patients use CAM. Physicians should be more aware of potential CAM use and more actively discuss the topic. More research is needed to gain knowledge about possible anticancer effects of CAM and their interactions with conventional therapies.

Background: Radiological grading of wrist osteoarthritis associated with scaphoid nonunion advanced collapse (SNAC) can be difficult. A comparison radiograph of the contralateral healthy wrist and an educational training in the various SNAC stages may improve reliability. Our purposes were to evaluate the difference in the reliability: (1) between observers who rate SNAC wrists with and without a comparison radiograph; and (2) between observers who receive training prior to ratings and those who do not. Methods: In this cross-sectional survey study, 82 fully trained orthopedic or hand surgeons rated anteroposterior radiographs of 19 patient wrists following a scaphoid nonunion based on SNAC stages 0 to 4. Observers were randomized online in 4 groups: one group rated unilateral views without training, a second group unilateral views with training, a third group bilateral views without training, and a fourth group bilateral views with training. Training included a 1-page clarification of the SNAC stages. Interobserver agreement was calculated using kappa statistics. Results: There was no significant difference between agreement between observers who rated unilateral radiographs (κ = 0.55) and who rated bilateral radiographs (κ = 0.58) ( P = .14), nor between agreement between observers who received training (κ = 0.59) and who did not (κ = 0.54) ( P = .058). Conclusions: The use of an additional comparison view and/or training does not seem to be clinically relevant in SNAC staging. There is room for improvement in the way we assess patients with SNAC wrists.

<p class="abstract"><strong>Background:</strong> Plantar fasciitis (PF) is considered as degenerative tendinopathies. Repeated micro trauma is the major etiology of these diseases. Autologous platelet rich plasma (PRP) injections are becoming more popular in the treatment of enthesopathies like PF. The growth factors in PRP cause tissue healing. We compared the result of injecting intra-lesional autologous PRP injections versus steroid infiltration in chronic PF.</p><p class="abstract"><strong>Methods:</strong> A prospective, interventional and analytic comparative study was done and 81 patients (120 heels) were included in this study and were followed up for 6 months. We assessed the outcome of each patient using visual analog score (VAS) and foot and ankle disability index (FADI) on follow-up at 1, 3, and 6 months. <strong></strong></p><p class="abstract"><strong>Results:</strong> In our study, female preponderance was seen. Left side was more common as compared to right side. Unilateral PF is more common than bilateral. The difference with in the individual group at baseline and at 1,3 and 6 months was statistically highly significant in terms of VAS and FADI (p=0.0001) But the difference in the between the two groups was insignificant for VAS and FADI at 1, 3 and 6 months.</p><p class="abstract"><strong>Conclusions:</strong> In our study, as there is no significant difference in VAS and FADI score between corticosteroid injection group and PRP injection group at 1, 3 and 6 months follow up. So, it’s reasonable to conclude that both are equally effective in PF. But as PRP injection comes out to be more time consuming and more costly, corticosteroid seems to be more efficient, cost and time wise. Hence, the latter should be a better choice.      </p>

Artificial Intelligence (AI) systems could improve system efficiency by supporting clinicians in making appropriate referrals. However, they are imperfect by nature and misdiagnoses, if not correctly identified, can have consequences for patient care. In this paper, findings from an online survey are presented to understand the aptitude of GPs (n = 50) in appropriately trusting or not trusting the output of a fictitious AI-based decision support tool when assessing skin lesions, and to identify which individual characteristics could make GPs less prone to adhere to erroneous diagnostics results. The findings suggest that, when the AI was correct, the GPs’ ability to correctly diagnose a skin lesion significantly improved after receiving correct AI information, from 73.6% to 86.8% (X2 (1, N = 50) = 21.787, p < 0.001), with significant effects for both the benign (X2 (1, N = 50) = 21, p < 0.001) and malignant cases (X2 (1, N = 50) = 4.654, p = 0.031). However, when the AI provided erroneous information, only 10% of the GPs were able to correctly disagree with the indication of the AI in terms of diagnosis (d-AIW M: 0.12, SD: 0.37), and only 14% of participants were able to correctly decide the management plan despite the AI insights (d-AIW M:0.12, SD: 0.32). The analysis of the difference between groups in terms of individual characteristics suggested that GPs with domain knowledge in dermatology were better at rejecting the wrong insights from AI.

Internet and telecommunication is nowadays one of the core necessities and is in fact required in every aspect of our daily lives. Bhutan introduced the internet and television in 1999. Internet and telecommunication has taken its roots in Bhutan and in every nook and cranny of the country. Given its importance, it is important to time to time assess its quality in the country for learning and development purposes. The study is based on quantitative analysis, using the SERVQUAL instrument. The data was collected through randomly distributed questionnaires through convenience sampling method via google form survey. Sample size of 384 was determined using an online survey monkey tool. The data for this study was analyzed using excel through paired two sample t-test to compare means and to see the significant difference between expectation and perception of the services of each dimension item of all the five dimensions at hypothesized mean difference of zero, alpha value of 0.05. The average gap score is at -0.6 which means that the expectations have not been met and quality of internet service is unsatisfactory. Interesting to note that TANGIBILITY, EMPATHY and RELIABILITY aspects require immediate attention. Generally, the difference between the two means is statistically significant, and therefore there is a statistical significant difference between perceived and expected internet service quality. The study therefore, recommends the (internet service providers) ISPs to consider improvements and rethinking developments on the dimensions discussed in the paper.

We study choice of profession in three groups of Russian-speaking Jewish families with different occupational distributions of the ancestors. This study continues exploration of the persistence of social status of families over centuries that was initiated in recent years. It was found previously that in some cases professions remain associated with the same surnames for many generations. Here the studied groups are defined by a class of the surname of individuals composing them. The class serves as a label that indicates a professional bias of the ancestors of the individual. One group are the bearers of the class of surnames which were used by rabbinical dynasties. The other group is constituted by occupational surnames, mostly connected to crafts. Finally, the last group are generic Jewish names defined as surnames belonging to neither of the above groups. We use the self-collected database that consists of 858 and 1057 of the first two groups, respectively, and 7471 generic Jewish surnames. The statistics of the database are those of individuals drawn at random from the considered groups. We determine shares of members of the groups working in a given type of occupations together with the confidence interval. The occupational type’s definition agrees with International Standard Classification of Occupations. It is demonstrated that there is a statistically significant difference in the occupational structure of the three groups that holds beyond the uncertainty allowed by 95% confidence interval. We quantify the difference with a numerical measure of the overlap of professional preferences of different groups. We conclude that in our study the occupational bias of different population groups is preserved at least for two centuries that passed since the considered surnames appeared.

Background: During the coronavirus disease 2019 (COVID-19) pandemic, the Italian government has adopted containment measures to control the virus’s spread, including limitations to the practice of physical activity (PA). The aim of this study was to estimate the levels of PA, expressed as energy expenditure (MET–minute/week), among the physically active Sicilian population before and during the last seven days of the COVID-19 quarantine. Furthermore, the relation between this parameter and specific demographic and anthropometric variables was analyzed. Methods: 802 Sicilian physically active participants (mean age: 32.27 ± 12.81 years; BMI: 23.44 ± 3.33 kg/m2) were included in the study and grouped based on gender, age and BMI. An adapted version of the International Physical Activity Questionnaire—short form (IPAQ-SF) was administered to the participants through an online survey. The Wilcoxon signed-rank test and the Kruskal-Wallis rank-sum test were used for statistical analyses. Results: As expected, we observed a significant decrease of the total weekly energy expenditure during the COVID-19 quarantine (p < 0.001). A significant variation in the MET–min/wk in the before quarantine condition (p = 0.046) and in the difference between before and during quarantine (p = 0.009) was found for males and females. The male group decreased the PA level more than the female one. Moreover, a significant difference in the MET–min/wk was found among groups distributions of BMI (p < 0.001, during quarantine) and of age (p < 0.001, both before and during quarantine). In particular, the highest and the lowest levels of PA were reported by the young and the elderly, respectively, both before and during quarantine. Finally, the overweight group showed the lowest level of PA during quarantine. Conclusion: Based on our outcomes, we can determine that the current quarantine has negatively affected the practice of PA, with greater impacts among males and overweight subjects. In regards to different age groups, the young, young adults and adults were more affected than senior adults and the elderly.

AbstractIntroduction: Annual ambulance diversion hours in Boston increased more than six-fold from 1997 to 2006. Although interventions and best practices were implemented, there was no reduction in the number of diversion hours.Objectives: A consortium of Boston teaching hospitals instituted a two-week moratorium on citywide diversion from 02 October 2006 to 15 October 2006. The hypothesis was that there would be no significant difference in measures of hospital and emergency medical services (EMS) efficiency compared with the two weeks immediately prior.Methods: A total of nine hospitals and the municipal emergency medical services in Boston submitted data for analysis. The following mean daily hospital measures were studied: (1) emergency department volume; (2) number of emergency department admissions; (3) length of stay (LOS) for all patients; and (4) number of elopements. Mean EMS at-hospital time by destination and the percent of all Boston EMS transports to each hospital destination were calculated. The median differences (MD) were calculated as “before” minus “during” the study period and were compared with paired, Wilcoxon, non-parametric tests. Additional mean EMS measures for all destinations included: (1) to hospital time; (2) number of responses with transport initiated per day; (3) incident entry to arrival; and (4) at-hospital time.Results: The LOS for admitted patients (MD = 0.30 hours; IQR 0.10,1.30; p = 0.03) and number of daily admissions (MD = -1.50 patients; IQR -1.50, -0.10; p = 0.04) were significantly different statistically. The results for LOS for all patients, LOS for discharged patients, ED volume, EMS time at hospital by destination, number of elopements, and percent of Boston EMS transports to each hospital revealed no statistically significant differences. The difference between the study and control periods for mean EMS to hospital time, at-hospital time, and incident entry to arrival was a maximum of 0.6 minutes. The vast majority of EMS respondents to an online survey believed that the “no diversion” policy should be made routine practice.Conclusions: The LOS for admitted patients decreased by 18 minutes, and the number of admissions increased by 1.5 patients per day during the study period. The “no diversion” policy resulted in minimal changes in EMS efficiency and operations. Diversion was temporarily eliminated in a major city without significant detrimental changes in ED, hospital, or EMS efficiency.

Background: Impostor Phenomenon is described as the psychological experience in which there is the individual does not have the ability to believe that the accomplishments achieved by him/her are deserved or are achieved because of one’s own skills and talents, but because of one being fortunate. Impostor Phenomenon is seen in many professional setting and is also prominent in highly successful individuals. Impostor phenomenon is increasing among the health care professionals. The following study determines the prevalence of Impostor Phenomenon in Physiotherapy professionals. Method: The study was conducted through online survey method. Simple random sampling was done and forms were sent to the physiotherapists. 200 participants responded to the questionnaire. Clance Impostor Phenomenon Scale was used to measure Impostor Phenomenon. Demographic data was collected and questionnaire was filled by the participants. Total scoring was done and the participants were classified according to categories of Clance Impostor Phenomenon Scale. Result: 7.5% of physiotherapists had few impostor characteristics, 58% experienced moderate impostor characteristics, 32% having often impostor characteristics and 2.5% of had intense Impostor Phenomenon. The scoring of male and female physiotherapists was similar and the scores of clinicians were more than academicians. Conclusion: The study concluded that Impostor Phenomenon affected the Physiotherapists. Many of physiotherapists scored between 40-60 and indicated having the characteristics of Impostor Phenomenon at a moderate level. No significant difference was seen between males and females. The prevalence of Impostor Phenomenon in clinicians was higher than in academicians. Key words: Impostor Phenomenon, Health care professionals, Physiotherapists.
