Introduction: Obesity has long been associated with all-cause mortality and cardiovascular disease (CVD). Visceral abdominal tissue (VAT) has been proposed as an important CVD risk stratification metric given its independent correlation with myocardial infarction and stroke. This study aims to clarify the relationship between the presence and severity of VAT with the presence and severity of coronary artery plaque as defined by total plaque volume, calcified plaque volume, non-calcified plaque volume, and high risk low-density non-calcified plaque using quantitative coronary computed tomography atherosclerosis imaging (AI-QCT).
Method(s): CCTA was performed using single or dual source CT scanners of >64-detector rows. Coronary atherosclerosis evaluation by CCTA (AI-QCT) was performed. The AI-based approach to CCTA interpretation in this study was performed using an FDA-cleared software service (Cleerly Lab, Cleerly, New York, NY) that performs automated analysis of CCTA using a series of validated convolutional neural network models (including VGG19 network, 3D U-Net, and VGG Network Variant) for image quality assessment, coronary segmentation and labeling, lumen wall evaluation and vessel contour determination and plaque characterization. Coronary segments with a diameter >1.5 mm were included in the analysis using the modified 18-segment SCCT model. Plaque volume was categorized using Hounsfield unit (HU) ranges, with LD-NCP defined as plaques <30 HU, NCP defined as HU between -30 and +350, and CP defined as >350 HU12,13.
Result(s): The study cohort was comprised of 145 patients, 56.1 +/- 8.5 years, 84.0% male. Overall, 3.5% had a history of diabetes, 19% hypertension, 38% dyslipidemia, 8% current smokers, and 34% had a family history of CAD. At the time of the examination, 37% were taking statins, 21% anti-hypertension medications, and 11% non-stating lipid lowering medication. There was a stepwise progression of the median coronary plaque volume for each quartile of visceral fat including TPV (Q1: 19.8, Q2: 48.1, Q3: 86.4, and Q4: 136.6 mm³ (P=0.0098)), NCP (Q1: 15.7, Q2: 35.4, Q3: 86.4, and Q4: 136.6 mm³ (P=0.0032)) and LD-NCP (Q1: 0.6, Q2: 0.81, Q3: 2.0, and Q4: 5.0 mm³ (P<0.0001)). There was also a stepwise progression of the median maximum diameter stenosis for each quartile of visceral fat (Q1: 18.0, Q2: 27.0, Q3: 27.5, and Q4: 29.5% (P=0.0414)) as well as medial coronary plaque length (Q1: 12.8, Q2: 19.5, Q3: 26.4, and Q4: 27.5mm (P=0.0077))
Conclusion(s): Our findings represent the first demonstration of a stepwise progression with regards to visceral abdominal tissue and total plaque volume, non-calcified plaque volume, and low density non-calcified plaque volume. This relationship is particularly striking with regards to the progression and severity of VAT and the presence and amount of low density non-calcified plaque, which is known to be high risk for cardiovascular events.

BACKGROUND:Vaccine hesitancy is challenging for clinicians and of increasing concern since COVID-19 vaccination rollout began. Standardized patients (SPs) provide an ideal method for assessing resident physicians' current skills, providing opportunity to practice and gain immediate feedback, while also informing evaluation of curriculum and training. As such, we designed and implemented an OSCE station where residents were tasked with engaging and educating a vaccine-hesitant patient. AIM/OBJECTIVE:Describe residents' vaccine counseling practices, core communication and interpersonal skills, and effectiveness in meeting the objectives of the case. Explore how effectiveness in overcoming vaccine hesitancy may be associated with communication and interpersonal skills in order to inform educational efforts. SETTING/METHODS:Annual OSCE at a simulation center. PARTICIPANTS/METHODS:106 internal medicine residents (51% PGY1, 49% PGY2). PROGRAM DESCRIPTION/METHODS:Residents participated in an annual residency-wide, multi-station OSCE, one of which included a Black, middle-aged, vaccine-hesitant male presenting for a routine video visit. Residents had 10 min to complete the encounter, during which they sought to educate, explore concerns, and make a recommendation. After each encounter, faculty gave residents feedback on their counseling skills and reviewed best practices for effective communication on the topic. SPs completed a behaviorally anchored checklist (30 items across 7 clinical skill domains and 2 measures of trust in the vaccine's safety and resident) which will inform future curriculum. PROGRAM EVALUATION/RESULTS:Fifty-five percent (SD: 43%) of the residents performed well on the vaccine-specific education domain. PGY2 residents scored significantly higher on two of the seven domains compared to PGY1s (patient education/counseling-PGY1: 35% (SD: 36%) vs. PGY2: 52% (SD: 41%), p = 0.044 and activation-PGY1: 37% (SD: 45%) vs. PGY2: 59% (SD: 46%), p = 0.016). In regression analyses, education/counseling and vaccine-specific communication skills were strongly, positively associated with trust in the resident and in the vaccine's safety. A review of qualitative data from the SPs' perspective suggested that low performers did not use patient-centered communication skills. DISCUSSION/CONCLUSIONS:This needs assessment suggests that many residents needed in-the-moment feedback, additional education, and vaccine-specific communication practice. Our program plans to reinforce evidence-based practices physicians can implement for vaccine hesitancy through ongoing curriculum, practice, and feedback. This type of needs assessment is replicable at other institutions and can be used, as we have, to ultimately shed light on next steps for programmatic improvement.

OBJECTIVE:To conduct a dimensional analysis to identify conceptual gaps around shared decision making (SDM) in reproductive health care and to refine the conceptual definition of SDM as related to contraceptive counseling. DATA SOURCES:We identified source data through systematic searches of the CINAHL and PubMed databases. STUDY SELECTION:We included peer-reviewed research and nonresearch articles that addressed contraceptive counseling for pregnancy prevention in the United States. We did not consider date of publication as an inclusion criterion. We included 35 articles in the final review. DATA EXTRACTION:Using dimensional analysis, we extracted data to clarify the definition of SDM as a socially constructed concept that varies by perspective and context. DATA SYNTHESIS:Data synthesis enabled us to compare SDM from patient and provider perspectives and to identify four primary dimensions of SDM that varied by context: Patient Preferences, Relationship, Provider Bias, and Clinical Suitability. CONCLUSION:The four dimensions we identified illustrate the complexity and depth of SDM in contraceptive counseling encounters and broaden the definition of SDM to more than an encounter in which decision making incorporates clinician expertise and patient participation. We identified several assumptions that indicate the need for improved understanding that SDM is not a universal concept across perspectives and contexts. Most researchers in the included articles addressed the Patient Preferences dimension. Fewer considered the patient-provider relationship, the effect of provider bias, and the effect of specific clinical circumstances on SDM. We propose a conceptual map and model that can be used to refine the concepts that inform SDM and guide providers and researchers. Future research is needed to address the remaining gaps.

BACKGROUND:The COVID-19 pandemic has increased utilization of educational technology for surgical education. Our aim was to determine attitudes and behaviors of surgical education champions towards virtual educational platforms and learner engagement. METHODS:An electronic survey was distributed to all Association of Surgical Education members addressing i) methods of engagement in virtual learning ii) ways to improve engagement and iii) what influences engagement. Stratified analysis was used to evaluate differences in responses by age, gender, level of training and specialty. RESULTS:154 ASE members completed the survey (13% response rate). 88% respondents accessed virtual learning events at home. Most (87%) had joined a virtual learning event and then participated in another activity. 1 in 5 who did this did so "always" or "often". Female respondents were more likely than males to join audio and then participate in another activity (62.3% v 37.7%, p = 0.04). CONCLUSIONS:Virtual platforms do not automatically translate into increased learner engagement. Careful design of educational strategies is essential to increase and maintain learner engagement when utilizing virtual surgical education.

BACKGROUND:The COVID-19 pandemic had its first peak in the United States between April and July of 2020, with incidence and prevalence rates of the virus the greatest in the northeastern coast of the country. At the time of study implementation, there were few studies capturing the perspectives of nurses working the frontlines of the pandemic in any setting as research output in the United States focused largely on treating the disease. OBJECTIVE:The purpose of this study was to capture the perspectives of nurses in the United States working the frontlines of the COVID-19 pandemic's first wave. We were specifically interested in examining the impact of the pandemic on nurses' roles, professional relationships, and the organizational cultures of their employers. DESIGN/METHODS:We conducted an online qualitative study with a pragmatic design to capture the perspectives of nurses working during the first wave of the United States COVID-19 pandemic. Through social networking recruitment, frontline nurses from across the country were invited to participate. Participants provided long form, text-based responses to four questions designed to capture their experiences. A combination of Latent Dirichlet Allocation--a natural language processing technique--along with traditional summative content analysis techniques were used to analyze the data. SETTING/METHODS:The United States during the COVID-19 pandemic's first wave between May and July of 2020. RESULTS:A total of 318 nurses participated from 29 out of 50 states, with 242 fully completing all questions. Findings suggested that the place of work mattered significantly in terms of the frontline working experience. It influenced role changes, risk assumption, interprofessional teamwork experiences, and ultimately, likelihood to leave their jobs or the profession altogether. Organizational culture and its influence on pandemic response implementation was a critical feature of their experiences. CONCLUSIONS:Findings suggest that organizational performance during the pandemic may be reflected in nursing workforce retention as the risk for workforce attrition appears high. It was also clear from the reports that nurses appear to have assumed higher occupational risks during the pandemic when compared to other providers. The 2020 data from this study also offered a number of signals about potential threats to the stability and sustainability of the US nursing workforce that are now manifesting. The findings underscore the importance of conducting health workforce research during a crisis in order to discern the signals of future problems or for long-term crisis response. TWEETABLE ABSTRACT/CONCLUSIONS:Healthcare leaders made the difference for nurses during the pandemic. How many nurses leave their employer in the next year will tell you who was good, who wasn't.

BACKGROUND:Standard-of-care first-line chemotherapy for epithelial ovarian cancer is carboplatin and paclitaxel administered once every 3 weeks. The JGOG 3016 trial reported significant improvement in progression-free and overall survival with dose-dense weekly paclitaxel and 3-weekly (ie, once every 3 weeks) carboplatin. However, this benefit was not observed in the previously reported progression-free survival results of ICON8. Here, we present the final coprimary outcomes of overall survival and updated progression-free survival analyses of ICON8. METHODS:(group 3), all administered via intravenous infusion for a total of six 21-day cycles. Coprimary outcomes were progression-free survival and overall survival, with comparisons done between group 2 and group 1, and group 3 and group 1, in the intention-to-treat population. Safety was assessed in all patients who started at least one chemotherapy cycle. The trial is registered on ClinicalTrials.gov, NCT01654146, and ISRCTN registry, ISRCTN10356387, and is closed to accrual. FINDINGS:Between June 6, 2011, and Nov 28, 2014, 1566 patients were randomly assigned to group 1 (n=522), group 2 (n=523), or group 3 (n=521). The median age was 62 years (IQR 54-68), 1073 (69%) of 1566 patients had high-grade serous carcinoma, 1119 (71%) had stage IIIC-IV disease, and 745 (48%) had IPS. As of data cutoff (March 31, 2020), with a median follow-up of 69 months (IQR 61-75), no significant difference in overall survival was observed in either comparison: median overall survival of 47·4 months (95% CI 43·1-54·8) in group 1, 54·8 months (46·6-61·6) in group 2, and 53·4 months (49·2-59·6) in group 3 (group 2 vs group 1: hazard ratio 0·87 [97·5% CI 0·73-1·05]; group 3 vs group 1: 0·91 [0·76-1·09]). No significant difference was observed for progression-free survival in either comparison and evidence of non-proportional hazards was seen (p=0·037), with restricted mean survival time of 23·9 months (97·5% CI 22·1-25·6) in group 1, 25·3 months (23·6-27·1) in group 2, and 24·8 months (23·0-26·5) in group 3. The most common grade 3-4 adverse events were reduced neutrophil count (78 [15%] of 511 patients in group 1, 183 [36%] of 514 in group 2, and 154 [30%] of 513 in group 3), reduced white blood cell count (22 [4%] in group 1, 80 [16%] in group 2, and 71 [14%] in group 3), and anaemia (26 [5%] in group 1, 66 [13%] in group 2, and 24 [5%] in group 3). No new serious adverse events were reported. Seven treatment-related deaths were reported (two in group 1, four in group 2, and one in group 3). INTERPRETATION:In our cohort of predominantly European women with epithelial ovarian cancer, we found that first-line weekly dose-dense chemotherapy did not improve overall or progression-free survival compared with standard 3-weekly chemotherapy and should not be used as part of standard multimodality front-line therapy in this patient group.

PURPOSE/OBJECTIVE:Driveline infection (DLI) is a significant source of morbidity and mortality during left ventricular assist device (LVAD) support yet limited studies are available to describe the center-level prevalence, preventive practices, and their potential effectiveness. METHODS:We surveyed LVAD centers in the United States to determine program burden and preventive practices for DLI during HeartMate (HM) 3 support. An online, anonymous, question-based survey was sent to expert providers at implanting centers. Only a single respondent completed the survey for each center. As an exploratory analysis, we compared specific DLI preventive practices between centers with low (≤10%) and high (>10%) reported prevalence of DLI. RESULTS:Seventy-eight centers responded to the survey (response rate: 50%). Respondents were comprised of 37 (47%) heart failure cardiologists, 27 (35%) LVAD coordinators, and 14 (18%) cardiothoracic surgeons. The prevalence of DLI during HM3 was reported as ≤10% by 27 (35%), 11%-25% by 36 (46%), and >25% by 16 (19%) centers. Thirteen (17%) centers had a body mass index threshold for device placement, 29 (37%) utilized a counter incision, 66 (81%) placed an anchor stitch, and 69 (88%) used an external device to stabilize the DL. Proportionally, more centers with a low DLI prevalence used a wound vacuum 6 (22%) versus 3 (6%, p = 0.03) than those with high DLI. CONCLUSION/CONCLUSIONS:Variation exists in reported prevalence and practices of preventing and managing driveline infections across centers during HM3 support. Further studies are warranted to develop and assess the effectiveness of standardized preventive strategies.
