The case for simplifying and using absolute targets for viral hepatitis elimination goals
The 69th World Health Assembly endorsed the Global Health Sector Strategy for Viral Hepatitis, embracing a goal to eliminate hepatitis infection as a public health threat by 2030. This was followed by the World Health Organization's (WHO) global targets for the care and management of hepatitis B virus (HBV) and hepatitis C virus (HCV) infections. These announcements and targets were important in raising awareness and calling for action; however, tracking countries' progress towards these elimination goals has provided insights to the limitations of these targets. The existing targets compare a country's progress relative to its 2015 values, penalizing countries who started their programmes prior to 2015, countries with a young population, or countries with a low prevalence. We recommend that (1) WHO simplify the hepatitis elimination targets, (2) change to absolute targets and (3) allow countries to achieve these disease targets with their own service coverage initiatives that will have the maximum impact. The recommended targets are as follows: reduce HCV new chronic cases to ≤5 per 100 000, reduce HBV prevalence among 1-year-olds to ≤0.1%, reduce HBV and HCV mortality to ≤5 per 100 000, and demonstrate HBV and HCV year-to-year decrease in new HCV- and HBV-related HCC cases. The objective of our recommendations is not to lower expectations or diminish the hepatitis elimination standards, but to provide clearer targets that recognize the past and current elimination efforts by countries, help measure progress towards true elimination, and motivate other countries to follow suit.

Respiratory impedance measured using impulse oscillometry in a healthy urban population
This study derives normative prediction equations for respiratory impedance in a healthy asymptomatic urban population using an impulse oscillation system (IOS). In addition, this study uses body mass index (BMI) in the equations to describe the effect of obesity on respiratory impedance. Data from an urban population comprising 472 healthy asymptomatic subjects that resided or worked in lower Manhattan, New York City were retrospectively analysed. This population was the control group from a previously completed case-control study of the health effects of exposure to World Trade Center dust. Since all subjects underwent spirometry and oscillometry, these previously collected data allowed a unique opportunity to derive normative prediction equations for oscillometry in an urban, lifetime non-smoking, asymptomatic population without underlying respiratory disease. Normative prediction equations for men and women were successfully developed for a broad range of respiratory oscillometry variables with narrow confidence bands. Models that used BMI as an independent predictor of oscillometry variables (in addition to age and height) demonstrated equivalent or better fit when compared with models that used weight. With increasing BMI, resistance and reactance increased compatible with lung and airway compression from mass loading. This study represents the largest cohort of healthy urban subjects assessed with an IOS device. Normative prediction equations were derived that should facilitate application of IOS in the clinical setting. In addition, the data suggest that modelling of lung function may be best performed using height and BMI as independent variables rather than the traditional approach of using height and weight.

Toward Understanding Movement-evoked Pain (MEP) and its Measurement: A Scoping Review
OBJECTIVE:Individuals with chronic pain conditions often report movement as exacerbating pain. An increasing number of researchers and clinicians have recognized the importance of measuring and distinguishing between movement-evoked pain (MEP) and pain at rest as an outcome. This scoping review maps the literature and describes MEP measurement techniques. METHOD/METHODS:The scoping review utilized six databases to identify original studies that targeted pain or movement-related outcomes. Our search returned 7,322 articles that were screened by title and abstract by two reviewers. The inclusion criteria focused on measurement of MEP before, during and after movement tasks in adults with chronic pain. Studies of children < 18 years of age or with non-human animals, case studies, qualitative studies, book chapters, cancer-related pain, non-English language and abstracts with no full publish text were excluded from the study. RESULTS:Results from 38 studies revealed great variation in the measurement of MEP, while almost all of the studies did not provide an explicit conceptual or operational definition for MEP. Additionally, studies collectively illuminated differences in MEP compared to rest pain, movement provocation methods, and pain intensity as the primary outcome. DISCUSSION/CONCLUSIONS:These results have clinically significant and research implications. To advance the study of MEP, we offer that consistent terminology, standardized measurement (appropriate for pain type/population), and clear methodological processes be provided in research publications. Based on the findings, we have put forth a preliminary definition MEP which may benefit from continued scholarly dialogue.

Using an osce to teach neurology residents to discuss prognosis after hypoxic ischemic brain injury [Meeting Abstract]
INTRODUCTION: Clinicians caring for critically-ill patients must be able to discuss prognosis and deliver bad news. To teach Neurology residents how to do this, we designed an objective structured clinical examination (OSCE) case in which trainees discussed prognosis with a standardized patient (SP).
METHOD(S): In 2017, in conjunction with the NYU School of Medicine Simulation Center, neurology faculty designed an OSCE case in which a resident was tasked with informing a SP her father had severe global hypoxic ischemic injury. The SP was instructed to assess the resident's ability to 1) explain the neurologic findings and 2) to respond to an emotional outburst. A neurology attending observed the encounter via one-way glass. After a 10-minute encounter, the resident was provided 5 minutes of feedback. The residents were surveyed on how prepared they felt for the OSCE, how useful it was, how they rated their performance, and how much they learned from the activity via a Likert scale from 1 (worst) to 5 (best) and free text response. The SP completed a behavioral anchored checklist to assess the residents' ability to gather information, develop a relationship, provide education and counseling, present bad news, and maintain professionalism.
RESULT(S): 57 third and fourth year neurology residents completed the case from 2018-2020, 54 (95%) of whom completed the post-OSCE survey. Residents reported feeling moderately prepared (mean Likert score 3.7/5) and rated their performance as average (3.4/5). Overall they found the case to be very helpful (4.6/5). Several reported difficultly with 1) addressing a complex medical case in a limited amount of time 2) reacting appropriately to an emotional family member and 3) avoiding medical jargon. The SP reported that residents performed well in the realms of non-verbal behavior enriched communication, being non-judgmental, not interrupting, acknowledging emotion, and avoiding medical jargon. Areas in which there was room for improvement included collaborating with the SP to decide upon next steps, identifying a support system, and asking "what is going through your mind right now?".
CONCLUSION(S): OSCE cases can be used to teach clinicians how to discuss prognosis and break bad news. Feedback about this simulation was positive, however its efficacy has yet to be evaluated

Prognostic value of coronary artery calcium score, area, and density among individuals on statin therapy vs. non-users: The coronary artery calcium consortium
BACKGROUND AND AIMS:Statins do not decrease coronary artery calcium (CAC) and may increase existing calcification or its density. Therefore, we examined the prognostic significance of CAC among statin users at the time of CAC scanning. METHODS:We included 28,025 patients (6151 statin-users) aged 40-75 years from the CAC Consortium. Cox regression models were used to assess the association of CAC with coronary heart disease (CHD) and cardiovascular disease (CVD) mortality. Models were adjusted for traditional CVD risk factors. Additionally, we examined the predictive performance of CAC components including CAC area, volume, and density using an age- and sex-adjusted Cox regression model. RESULTS:Participants (mean age 53.9 ± 10.3 years, 65.0% male) were followed for median 11.2 years. There were 395 CVD and 182 CHD deaths. One unit increase in log CAC score was associated with increased risk of CVD mortality (hazard ratio (HR), 1.2; 95% CI = 1.1-1.3) and CHD mortality (HR, 1.2; 95% CI = 1.1-1.4)) among statin users. There was a small but significant negative interaction between CAC score and statin use for the prediction of CHD (p-value = 0.036) and CVD mortality (p-value = 0.025). The volume score and CAC area were similarly associated with outcomes in statin users and non-users. Density was associated with CVD and CHD mortality in statin naïve patients, but with neither in statin users. CONCLUSION:CAC scoring retains robust risk prediction in statin users, and the changing relationship of CAC density with outcomes may explain the slightly weaker relationship of CAC with outcomes in statin users.

Comparison of automated and expert human grading of diabetic retinopathy using smartphone-based retinal photography
PURPOSE:The aim of this study is to investigate the efficacy of a mobile platform that combines smartphone-based retinal imaging with automated grading for determining the presence of referral-warranted diabetic retinopathy (RWDR). METHODS:A smartphone-based camera (RetinaScope) was used by non-ophthalmic personnel to image the retina of patients with diabetes. Images were analyzed with the Eyenuk EyeArt® system, which generated referral recommendations based on presence of diabetic retinopathy (DR) and/or markers for clinically significant macular oedema. Images were independently evaluated by two masked readers and categorized as refer/no refer. The accuracies of the graders and automated interpretation were determined by comparing results to gold standard clinical diagnoses. RESULTS:A total of 119 eyes from 69 patients were included. RWDR was present in 88 eyes (73.9%) and in 54 patients (78.3%). At the patient-level, automated interpretation had a sensitivity of 87.0% and specificity of 78.6%; grader 1 had a sensitivity of 96.3% and specificity of 42.9%; grader 2 had a sensitivity of 92.5% and specificity of 50.0%. At the eye-level, automated interpretation had a sensitivity of 77.8% and specificity of 71.5%; grader 1 had a sensitivity of 94.0% and specificity of 52.2%; grader 2 had a sensitivity of 89.5% and specificity of 66.9%. DISCUSSION:Retinal photography with RetinaScope combined with automated interpretation by EyeArt achieved a lower sensitivity but higher specificity than trained expert graders. Feasibility testing was performed using non-ophthalmic personnel in a retina clinic with high disease burden. Additional studies are needed to assess efficacy of screening diabetic patients from general population.

What did you say?: Assessing a virtualgoscetotrain RAS who recruit older adults to clinical trials [Meeting Abstract]
LEARNINGOBJECTIVES 1: Interpersonal /Communication Skill: 1) Identify communication skills needed to recruit older adults LEARNING OBJECTIVES 2: 2) Assess feasibility of GOSCEs to enhance recruitment skills in RAs. SETTING AND PARTICIPANTS: Convenience sample of 18 (5 male, 13 female) Research Assistants (RAs) at an urban hospital who recruit older adults for clinical trials. DESCRIPTION: Increasing older adults' participation in clinical trials is urgently needed. We developed a remote, three station simulation (Group Objective Structured Clinical Exam - GOSCE) to teach RAs communication skills. This 2-hour course included a discussion of challenges in recruiting older adults; skills practice with Standardized Participants (SPs); and a debrief to review experiences, highlight best practices. After discussion, RAs rotated (3 per group) through the stations, each with SP and faculty observer who provided immediate feedback. Thus, learners had opportunities for active and observational learning.Scenarios were: 1) an older white woman with hearing impairment; 2) an older white woman and family member together; and 3) an older Black man mistrustful due to history of racism in medical research. SPs completed behaviorally anchored checklists (11 communication skills across all cases, and 5-7 case-specific questions). Learners completed a 36- item survey of self-assessed change in skill after the workshop; insights on recruitment practice; and educational value. EVALUATION: The communication checklist across all cases included: relationship development (5 items, mean of 58% well done (range: 50-75%), patient education (3 items, 44% (42-58%)), patient satisfaction (2 items, 54% (50-58%)), and information gathering (1 item, 92%). Seventeen RAs completed the survey, 100% felt the workshop provided valuable feedback and taught relevant material, 88% would participate again and 52%reported that the workshop improved their recruitment skills. All RAs reported encountering situations similar to hearing impairment and family member cases, and the majority rated the cases as high in educational value. Just 45% reported experiencing a case similar to the Black male case, and 100% rate it as high in educational value. Key points identified by RAs included the value of building a trusting relationship with potential subjects, recognizing possible barriers to communication early on and addressing these directly in a supportive and respectful style. DISCUSSION / REFLECTION / LESSONS LEARNED: Remote GOSCEs are a feasible mechanism for training RAs in subject recruitment focused on the unique needs of older adults. Responses to the RA survey suggest that GOSCEs are feasible for training RAs in simulated clinical scenarios with which participants are familiar and unfamiliar. SP assessment of RAs identified areas for further reinforcement to improve recruitment skills. This innovation is a feasible, high yield strategy for training research staff. It is highly adaptable to the specific recruitment needs and skills of a clinical trials and will add to the literature on educating RAs

Training Medical Students in Diet Assessment and Brief Counseling
Poor dietary choices are a leading cause of chronic disease, but nutrition is rarely discussed in clinical practice. Nutrition is taught in less than a third of medical schools and physicians in practice empirically report low levels of comfort and self-efficacy in discussing nutrition with patients. A two-part presentation was created and shared with second-year medical students at a college of medicine. Students were given pre-work that included a brief (15 minutes) pre-recorded presentation and an e-resource entitled "Practical Nutrition for the Primary Care Provider" and then engaged in a live virtual session with a brief lecture and question and answer period (45 minutes). A survey was administered following the live presentation to evaluate the extent to which the presentation met the stated objectives and could impact participants' future practice. One-hundred and six students participated in the live lecture. Eighty-eight students (83%) provided survey feedback. Over two-thirds of respondents indicated that the presentation completely met the objectives, 57% indicated that they would definitely talk to patients with chronic disease about nutrition, and 52% indicated they would incorporate diet assessment in visits with patients with chronic disease. Nutrition is integral to disease prevention and management. Many students provided comments on the importance of the topic and benefit of the information. Further research is necessary to determine the optimal time and place for nutrition education in medical training. This presentation and e-resource are evidence-based, brief, and provided tools for participants to access once in practice.
