Speed And Accuracy

This work aimed to assist physicians by improving their speed and diagnostic accuracy when interpreting portable CXRs as well as monitoring the treatment process to see whether a patient is improving or deteriorating with treatment. These objectives are in especially high demand in the setting of the ongoing COVID-19 pandemic. With the recent progress in the development of artificial intelligence (AI), we introduce new deep learning frameworks to align and enhance the quality of portable CXRs to be more consistent, and to more closely match higher quality conventional CXRs. These enhanced portable CXRs can then help the doctors provide faster and more accurate diagnosis and treatment planning. The contributions of this work are four-fold. Firstly, a new database collection of subject-pair radiographs is introduced. For each subject, we collected a pair of samples from both portable and conventional machines. Secondly, a new deep learning approach is presented to align the subject-pairs dataset to obtain a pixel-pairs dataset. Thirdly, a new PairFlow approach is presented, an end-to-end invertible transfer deep learning method, to enhance the degraded quality of portable CXRs. Finally, the performance of the proposed system is evaluated by UAMS doctors in terms of both image quality and topological properties. This work was undertaken in collaboration with the Department of Radiology at the University of Arkansas for Medical Sciences (UAMS) to enhance portable/mobile COVID-19 CXRs, to improve the speed and accuracy of portable CXR images and aid in urgent COVID-19 diagnosis, monitoring and treatment.

Background: Medical school learning communities benefit students. The College of Medicine (COM) at the University of Arkansas for Medical Sciences (UAMS) provides medical students with academic, professional, and personal support through a learning community (LC) made of 7 academic houses. Objectives: To evaluate the effectiveness of the academic house model at UAMS utilizing a mixed-methods survey. The aims were to: (1) assess student experience and satisfaction with academic houses, (2) describe the realms of advising and guidance, and (3) identify areas for improvement. Method: An online survey was assigned to 723 COM students (all students enrolled, first through fourth years) at UAMS in March 2019. The survey was comprised of 25 items (10 multiple-choice, 8 on the Likert scale, and 7 open-ended questions). Data was depicted using frequency and percentages and/or thematic review of free-form responses. Results: The survey response rate was 31% (227 students). The majority of students responding (132, 58.1%) attended 2 or more face-to-face meetings with the faculty advisor within the preceding year. However, 27 (11.9%) students did not have any meetings. Approximately two-thirds of the respondents were satisfied or very satisfied with the guidance and direction provided by their advisors [very satisfied (n = 83; 36.6%); satisfied (n = 77; 33.9%)]. Themes that emerged from student generated areas for improvement include time constraints, advisor/advisee interest mismatch, and perceived inadequacy of advising content/connections. Conclusions: This study confirms the effectiveness of the LC model for advising and mentoring in the COM at UAMS. Uniquely, this study identifies not only learners’ satisfaction with their LC but also highlights areas for improvement which are widely generalizable and important to consider for institutions with or planning to start an LC.

Major Diagnosis

Abstract Context.—With the advent of modern diagnostic technology, use of the autopsy as a means of assessing diagnostic accuracy has declined precipitously. Interestingly, during the same period, the rate of misdiagnosis found at autopsy has not changed. Objectives.—To ascertain why an autopsy was requested, whether or not questions asked by clinicians were specifically addressed, and what types of misdiagnoses were found. Design.—One hundred forty-two consecutive autopsy records from the University of Arkansas for Medical Sciences Hospital were reviewed. In the same period, 715 deaths occurred, giving an overall autopsy rate of 20.14%. Results.—Of the 125 autopsies in which the problem-oriented autopsy request was available for review, a reason for the autopsy was given in only 69 cases (55%). One hundred three clinical questions were asked, and of these, 81 were specifically addressed in the final anatomic diagnosis, 10 were addressed in some part of the autopsy report but not in the final anatomic diagnosis, 10 were not addressed at all, and 2 could not be answered by the autopsy. Sixty-one autopsies revealed 81 misdiagnoses: 47 class I (missed major diagnosis that, if detected before death, could have led to a change in management that might have resulted in cure or prolonged survival) and 34 class II misdiagnoses (missed major diagnosis in which antemortem detection would have not led to a change in management). Conclusions.—The autopsy continues to be a vital part of medical education and quality assurance. It is important for the clinician to provide a clinical summary and specific clinical questions to be addressed or to speak directly with the pathologist and for the pathologist to provide answers that are easily accessible within the autopsy report. In this way, a problem-oriented autopsy can be performed based on questions raised by the clinician and the pathologist as a result of the gross dissection and microscopic evaluation.

This chapter introduces the description of wiki appropriation. It considers the tool inclusion in an online educational innovation, supported in student and group-centered learning approach, to improve the quality of the blended learning offered. It states that the university course of educational technology, through wiki application as an appropriated methodology, beyond its consideration as a Web 2.0 tool, gives the opportunity to enhance the student protagonism into the deepening of the conceptual field of the subject by a collaborative knowledge construction. The evidence shows that the application worth to develop the learning strategies towards the student comprehension and its social skills in universities contexts. The results shows that the transformation of reactive attitudes into creative ones is a long process of change mediated by emotions and metacognitive work. Both facilitate a change of the students’ focus, perspectives, and mentalities, understandable by the help of collective learning, among diverse variables.

Using the Quality Oncology Practice Initiative, an affiliate program of ASCO, we outlined opioid-associated constipation (OAC) as a subject in need of quality improvement (QI) in our fellowship program at the University of Arkansas for Medical Sciences and Central Arkansas Veterans Healthcare System. We initiated a fellow-led QI project to advance the quality of patient care and provide a valuable avenue for QI training of young physicians. Fellows organized meetings with all stakeholders, addressed the scope of the problem, and devised strategies for OAC management. Monthly meetings were organized using Plan-Do-Study-Act principles. Mandatory check boxes were inserted into our electronic medical record templates to remind all physicians to identify patients on opioid medications and assess and address OAC. Final chart audit and patient satisfaction surveys were performed 6 months after project initiation. Assessment of OAC improved from 52% at baseline to 92% ( P < .003). This improvement corresponded with high patient satisfaction scores, with 90% of surveyed patients reporting adequate management of their constipation. In this QI initiative, we showed that participation in ASCO’s Quality Oncology Practice Initiative helps identify areas in need of QI, and such fellow-led QI projects can serve as models for QI training of young physicians.

An important factor along with the availability of food is its quality. It depends, among other things, on the type of plant protection products used and the method of their application. This manuscript presents research on the possibility of using a shielded band sprayer in field onion cultivation. The shielded band spraying technology presented in this article is the subject of a patent application (application number P.428494-The prototype of the machine was produced in Poland in cooperation with the University of Life Sciences in Poznań). The research consisted in comparing the quantity and quality of the obtained crop, based on various methods of reducing the weed population. The research results indicate that the proposed shielded band spraying technology may affect the food quality (the active substance is not sprayed on onion plants) and profitability of farms (less use of plant protection products).

6564 Background: HNPCC, the most common cause of hereditary colorectal cancer (CRC), is inherited in an autosomal dominant fashion and caused by micro satellite instability and mutations in mismatch repair genes. Affected patients (pts) and first degree relatives tend to develop colonic and extra colonic tumors that need to be tested for the mutations. Genetic consultation (GC) should be routinely offered to the affected pts and relatives. To assess the utilization of GC, we assessed the frequency of referral for GC for the presence of HNPCC syndrome at our medical center. Methods: Patients with CRC were identified from the tumor registry at the University of Arkansas for Medical Sciences (UAMS) and the Central Arkansas Veterans Healthcare System (CAVHS) from January 1st 2000 to September, 2006. Pts’ charts were reviewed for synchronous or metachronous HNPCC tumors and family history (FH). FH was categorized as positive according to the Bethesda criteria (BC, 2000–2002), revised Bethesda criteria (RBC, 2003–2006), negative (documented FH but no h/o cancer) or inadequate documentation. Percentage of pts with positive FH for HNPCC syndrome and those with CRC less than 50 years of age (for pts diagnosed 2003–2006) who were referred for GC was calculated. The list of these pts was cross referenced to the list in genetics clinic at UAMS and CAVHS. Results: 858 patient charts were reviewed. Table 1 shows the number of pts meeting criteria for genetic counseling. 138 (16%) pts had inadequate /no documented FH. Of the 720 pts with documented FH, 67 (9.3%) had positive FH and 126(17%) met BC / RBC. Only 13 (10.3%) of 126 pts were referred for genetic counseling. The number of pts eligible for GC increased with inclusion of RBC. However, the percentage of eligible pts referred for GC was extremely low. Conclusions: FH is not adequately documented in many pts presenting with CRC. Only a small percentage of pts who qualify for GC are referred. Education of health care providers for referral to genetics counseling is warranted. No significant financial relationships to disclose. [Table: see text]
