RESUMEN

The global pandemic of COVID-19 caused by infection with SARS-CoV-2 is now entering its fourth year with little evidence of abatement. As of December 2022, the World Health Organization Coronavirus (COVID-19) Dashboard reported 643 million cumulative confirmed cases of COVID-19 worldwide and 98 million in the United States alone as the country with the highest number of cases. Although pneumonia with lung injury has been the manifestation of COVID-19 principally responsible for morbidity and mortality, myocardial inflammation and systolic dysfunction though uncommon are well-recognized features that also associate with adverse prognosis. Given the broad swath of the population infected with COVID-19, the large number of affected professional, collegiate, and amateur athletes raises concern regarding the safe resumption of athletic activity (return to play) following resolution of infection. A variety of different testing combinations that leverage ECG, echocardiography, circulating cardiac biomarkers, and cardiovascular magnetic resonance imaging have been proposed and implemented to mitigate risk. Cardiovascular magnetic resonance in particular affords high sensitivity for myocarditis but has been employed and interpreted nonuniformly in the context of COVID-19 thereby raising uncertainty as to the generalizability and clinical relevance of findings with respect to return to play. This consensus document synthesizes available evidence to contextualize the appropriate utilization of cardiovascular magnetic resonance in the return to play assessment of athletes with prior COVID-19 infection to facilitate informed, evidence-based decisions, while identifying knowledge gaps that merit further investigation.

RESUMEN

The global pandemic of coronavirus disease 2019 (COVID-19) caused by infection with severe acute respiratory suyndrome coronavirus 2 (SARS-CoV-2) is now entering its 4th year with little evidence of abatement. As of December 2022, the World Health Organization Coronavirus (COVID-19) Dashboard reported 643 million cumulative confirmed cases of COVID-19 worldwide and 98 million in the United States alone as the country with the highest number of cases. While pneumonia with lung injury has been the manifestation of COVID-19 principally responsible for morbidity and mortality, myocardial inflammation and systolic dysfunction though uncommon are well-recognized features that also associate with adverse prognosis. Given the broad swath of the population infected with COVID-19, the large number of affected professional, collegiate, and amateur athletes raises concern regarding the safe resumption of athletic activity (return to play, RTP) following resolution of infection. A variety of different testing combinations that leverage the electrocardiogram, echocardiography, circulating cardiac biomarkers, and cardiovascular magnetic resonance (CMR) imaging have been proposed and implemented to mitigate risk. CMR in particular affords high sensitivity for myocarditis but has been employed and interpreted non-uniformly in the context of COVID-19 thereby raising uncertainty as to the generalizability and clinical relevance of findings with respect to RTP. This consensus document synthesizes available evidence to contextualize the appropriate utilization of CMR in the RTP assessment of athletes with prior COVID-19 infection to facilitate informed, evidence-based decisions, while identifying knowledge gaps that merit further investigation.

RESUMEN

PURPOSE: To describe evolution and severity of radiographic findings and assess association with disease severity and outcomes in critically ill COVID-19 patients. MATERIALS AND METHODS: This retrospective study included 62 COVID-19 patients admitted to the intensive care unit (ICU). Clinical data was obtained from electronic medical records. A total of 270 chest radiographs were reviewed and qualitatively scored (CXR score) using a severity scale of 0-30. Radiographic findings were correlated with clinical severity and outcome. RESULTS: The CXR score increases from a median initial score of 10 at hospital presentation to the median peak CXR score of 18 within a median time of 4 days after hospitalization, and then slowly decreases to a median last CXR score of 15 in a median time of 12 days after hospitalization. The initial and peak CXR score was independently associated with invasive MV after adjusting for age, gender, body mass index, smoking, and comorbidities (Initial, odds ratio [OR]: 2.11 per 5-point increase, confidence interval [CI] 1.35-3.32, P= 0.001; Peak, OR: 2.50 per 5-point increase, CI 1.48-4.22, P= 0.001). Peak CXR scores were also independently associated with vasopressor usage (OR: 2.28 per 5-point increase, CI 1.30-3.98, P= 0.004). Peak CXR scores strongly correlated with the duration of invasive MV (Rho = 0.62, P< 0.001), while the initial CXR score (Rho = 0.26) and the peak CXR score (Rho = 0.27) correlated weakly with the sequential organ failure assessment score. No statistically significant associations were found between radiographic findings and mortality. CONCLUSIONS: Evolution of radiographic features indicates rapid disease progression and correlate with requirement for invasive MV or vasopressors but not mortality, which suggests potential nonpulmonary pathways to death in COVID-19.

RESUMEN

We previously created a mandatory, inpatient, hepatology resident curriculum that immediately improved comfort, knowledge, and career interest in chronic liver disease (CLD). The durability of these effects needs to be known to use this intervention to address the hepatologist shortage. Thus, we aimed to assess this curriculum's long-term outcomes on internal medicine (IM) residents' CLD comfort, knowledge, and career interest. From 2015 to 2019 at a single institution, one IM resident was always assigned to the rotation. Similar anonymous assessments were administered to incoming postgraduate year (PGY)-1 residents and graduating PGY-3 residents, including a historic control cohort that graduated in June 2015. At residency completion, the intervention cohort (n = 61) had significantly higher comfort (1, not at all comfortable/strongly disagree; 5, very comfortable/strongly agree) with both hepatology (e.g., hepatitis C, 2.5 vs. 3.3, P < 0.001) and common IM topics (e.g., heart failure, 3.6 vs. 4.8, P < 0.001) but not specialty topics lacking curricula (e.g., inflammatory bowel disease, 2.8 vs. 2.7, P = 0.54). Compared to the historic cohort (n = 27), the intervention cohort was more comfortable in several CLD topics (e.g., cirrhosis, 3.2 vs. 3.8; P = 0.005) and answered more questions correctly (65% vs. 55%; P = 0.04), but career interest was unchanged (1.9 vs. 1.8; P = 0.45). Many residents (33%) would consider a hepatology career if training were separated from gastroenterology. Conclusion: With the completion of a mandatory hepatology curriculum, residents' CLD comfort and knowledge durably improved and exceeded that of historic counterparts. Initial career interest was not sustained, perhaps due to prerequisite gastroenterology training. These findings suggest IM educational initiatives may better address hepatology workforce needs by generating comanagers than by recruiting trainees.

RESUMEN

BACKGROUND AND AIMS: Liver disease is prevalent in the United States, and as the population ages, an increasing number of patients are anticipated to present for care. The state of the current hepatology workforce and future demand for hepatology providers is not known. The aim of this study was to model future projections for hepatology workforce demand. APPROACH AND RESULTS: A workforce study of hepatology providers in the United States was completed using primary and secondary data sources. An integrated workforce framework model was used that combined socioeconomic factors that drive economic demand, epidemiological factors that drive need, and utilization rates of health care services. Supply and demand projections were calculated for adult and pediatric hepatology professionals. Sensitivity analyses were conducted to cover the feasible range of these assumptions. An electronic survey of American Association for the Study of Liver Diseases (AASLD) members whose practice included 50% or more hepatology was conducted. In 2018, the adult and pediatric workforce included 7,296 and 824 hepatology providers, respectively, composed of hepatologists, gastroenterologists, and advanced practice providers whose practice was ≥50% hepatology. The modeling analysis projects that in 2023, 2028, and 2033, there will be shortages of 10%, 23%, and 35% adult hepatology providers, respectively, and 19%, 20%, and 16% pediatric hepatology providers, respectively. In sensitivity analyses, a shortage of hepatology providers is predicted even under optimistic assumptions. Among the respondents to the survey, the median age was higher among gastroenterologists and general hepatologists compared with transplant hepatologists. The most common category treated by transplant hepatologists was general hepatology. CONCLUSIONS: There is an impending critical shortage of adult and pediatric hepatology providers. Strategies are needed to encourage clinicians to pursue hepatology, especially in areas outside of transplant centers.

RESUMEN

Ischemic heart disease is the number one cause of death of women in the United States, accounting for over a quarter of a million annual female deaths. Evidence within the last several decades supports sex-specific differences in the prevalence, symptoms, and prognosis of ischemic heart disease between men and women. Despite women having a lower burden of obstructive coronary artery disease compared with men, the prevalence of angina and mortality from ischemic heart disease is higher for women than men. In addition to ischemic heart disease, certain nonischemic conditions may also have sex-specific differences in clinical presentation and occurrence. With the rising utilization of noninvasive modalities for the diagnosis and management of ischemic heart disease, it is important for radiologists to be familiar with the unique considerations for imaging women with heart disease. The purpose of this review is to discuss challenges for detection of heart disease in women, examine performance of noninvasive modalities in the detection of ischemic heart disease, and discuss nonischemic cardiomyopathies unique to or prevalent in women. Considerations for cardiac imaging in pregnancy are also discussed. © RSNA, 2017.

RESUMEN

Purpose To conduct a multi-institutional, multireader study to compare the performance of digital tomosynthesis, dual-energy (DE) imaging, and conventional chest radiography for pulmonary nodule detection and management. Materials and Methods In this binational, institutional review board-approved, HIPAA-compliant prospective study, 158 subjects (43 subjects with normal findings) were enrolled at four institutions. Informed consent was obtained prior to enrollment. Subjects underwent chest computed tomography (CT) and imaging with conventional chest radiography (posteroanterior and lateral), DE imaging, and tomosynthesis with a flat-panel imaging device. Three experienced thoracic radiologists identified true locations of nodules (n = 516, 3-20-mm diameters) with CT and recommended case management by using Fleischner Society guidelines. Five other radiologists marked nodules and indicated case management by using images from conventional chest radiography, conventional chest radiography plus DE imaging, tomosynthesis, and tomosynthesis plus DE imaging. Sensitivity, specificity, and overall accuracy were measured by using the free-response receiver operating characteristic method and the receiver operating characteristic method for nodule detection and case management, respectively. Results were further analyzed according to nodule diameter categories (3-4 mm, >4 mm to 6 mm, >6 mm to 8 mm, and >8 mm to 20 mm). Results Maximum lesion localization fraction was higher for tomosynthesis than for conventional chest radiography in all nodule size categories (3.55-fold for all nodules, P < .001; 95% confidence interval [CI]: 2.96, 4.15). Case-level sensitivity was higher with tomosynthesis than with conventional chest radiography for all nodules (1.49-fold, P < .001; 95% CI: 1.25, 1.73). Case management decisions showed better overall accuracy with tomosynthesis than with conventional chest radiography, as given by the area under the receiver operating characteristic curve (1.23-fold, P < .001; 95% CI: 1.15, 1.32). There were no differences in any specificity measures. DE imaging did not significantly affect nodule detection when paired with either conventional chest radiography or tomosynthesis. Conclusion Tomosynthesis outperformed conventional chest radiography for lung nodule detection and determination of case management; DE imaging did not show significant differences over conventional chest radiography or tomosynthesis alone. These findings indicate performance likely achievable with a range of reader expertise. © RSNA, 2016 Online supplemental material is available for this article.

RESUMEN

Functional single ventricle (FSV) encompasses a spectrum of severe congenital heart disease. Patients with FSV are living longer than decades prior resulting in more frequent imaging both for surgical planning and functional evaluation. At each stage of surgical intervention, imaging plays a critical role in detecting postoperative complications and preprocedural planning. This article describes the unique imaging findings, including complications, that are most important to the referring physician or surgeon at each surgical stage of FSV management. A description of lesions that embody the diagnosis of FSV is also included.

RESUMEN

BACKGROUND AND AIM: The aim of this study is to assess paracentesis utilization and outcomes in hospitalized adults with cirrhosis and ascites. METHODS: The 2011 Nationwide Inpatient Sample was used to identify adults, non-electively admitted with diagnoses of cirrhosis and ascites. The primary endpoint was in-hospital mortality. Variables included patient and hospital demographics, early (Day 0 or 1) or late (Day 2 or later) paracentesis, hepatic decompensation, and spontaneous bacterial peritonitis. RESULTS: Out of 8 023 590 admissions, 31 614 met inclusion criteria. Among these hospitalizations, approximately 51% (16 133) underwent paracentesis. The overall in-hospital mortality rate was 7.6%. There was a significantly increased mortality among patients who did not undergo paracentesis (8.9% vs 6.3%, P < 0.001). Patients who did not receive paracentesis died 1.83 times more often in the hospital than those patients who did receive paracentesis (95% confidence interval 1.66-2.02). Patients undergoing early paracentesis showed a trend towards reduction in mortality (5.5% vs 7.5%) compared with those undergoing late paracentesis. Patients admitted on a weekend demonstrated less frequent use of early paracentesis (50% weekend vs 62% weekday) and demonstrated increased mortality (adjusted odds ratio 1.12 95% confidence interval 1.01-1.25). Among patients diagnosed with spontaneous bacterial peritonitis, early paracentesis was associated with shorter length of stay (7.55 vs 11.45 days, P < 0.001) and decreased hospitalization cost ($61 624 vs $107 484, P < 0.001). CONCLUSION: Paracentesis is under-utilized among cirrhotic patients presenting with ascites and is associated with decreased in-hospital mortality. These data support the use of paracentesis as a key inpatient quality measure among hospitalized adults with cirrhosis. Future studies are needed to investigate the barriers to paracentesis use on admission.
