Impact of a Resident-Driven Research Club on Scholarly Activity in an Academic Internal Medicine Residency Program During the COVID-19 Pandemic.

OBJECTIVES: Traditional journal clubs have been shown to be insufficient in improving residents' scholarly productivity, often due to the inability to sustain residents' interest and participation. Additionally, the 2019 novel coronavirus (COVID-19) pandemic restrictions caused a decline in academic scholarly productivity across residency programs. We evaluated the impact of a resident-led research club called 'journal café' on residents' scholarly productivity by comparing scholarly output between the journal café members and non-members during the COVID-19 pandemic. METHODS: The journal café was established in the 2012/2013 academic year by internal medicine residents of a university residency program in Atlanta, Georgia, to foster self-directed collaboration among residents based on shared interests in academic research. The journal café runs independently of the residency program's journal club. We categorized IM residents at our institution into journal café members and non-members and collected data on their research productivity during residency training and the COVID-19 pandemic. The survey was conducted between April and June 2021 and analyzed data presented using frequencies, tables, and appropriate charts. RESULTS: Sixty-eight residents (29 journal café members and 39 non-members) completed the survey (response rate of 85%). A significantly higher number of journal café members reported having five or more research publications (55.1% vs 7.1%, P < .001) and scientific presentations (48.3% vs 2.6%, P < .001) compared with non-members. Additionally, more journal café members published COVID-19-related research in peer-reviewed journals compared with non-members (68% vs 32%, n = 19). Finally, most of the residents cited the opportunity of a platform to share and brainstorm on research ideas as the reason for joining the journal café. CONCLUSION: We found an association between journal café participation and increased scholarly activity, particularly during the COVID-19 pandemic. Independent resident-led research clubs supported by the residency program may complement the traditional journal clubs and enhance residents' participation in research.

Young-onset colon cancer among people living with HIV in metropolitan Atlanta.

PURPOSE: Colon cancer is a leading cause of cancer-related morbidity and mortality in the USA. We sought to better characterize colon cancer among a predominantly Black cohort with and without HIV. METHODS: We retrospectively reviewed all patients (n = 1482) diagnosed with colon cancer between 2015 and 2019 at a large urban tertiary teaching hospital using ICD-9 and ICD-10 codes. In this cohort, 114 (7.7%) of the patients also had HIV. Descriptive summaries were performed for gender, age, race/ethnicity, insurance status, tobacco/alcohol use, and BMI. RESULTS: Among patients with colon cancer only, 50.51% (n = 691) were men and 49.49% (n = 677) were women. Among patients with both HIV and colon cancer, 78.95% (n = 90) were men and 21.05% (n = 24) were women (p-value < 0.001). The mean age of the colon cancer patient sample was 61.62 years for those without HIV and 51.31 years for those with HIV (p-value < 0.001). Persons with both HIV and colon cancer were more likely to have a lower BMI (p-value < 0.001) and a history of smoking and alcohol use (p-value < 0.001), compared to patients with colon cancer only. When accounting for BMI, tobacco, and alcohol use, those with HIV were 10 years younger than those without HIV, 95% CI, 7.3-13; p < 0.001. CONCLUSIONS: In this study, HIV positive status was a risk factor for developing colon cancer at a younger age. Larger observational studies with multivariable analysis should be done to better describe the risk of colon cancer and HIV.

Association between race and risk of ICU mortality in mechanically ventilated COVID-19 patients at a safety net hospital.

PURPOSE: To determine racial differences in intensive care unit (ICU) mortality outcomes among mechanically ventilated patients with severe coronavirus disease 2019 (COVID-19) infection in a safety net hospital. METHODS: We retrospectively analyzed a cohort of patients ≥ 18 years old with confirmed severe acute respiratory syndrome-CoV-2 disease associated respiratory failure who were treated with invasive mechanical ventilation and admitted to the ICU from May 1, 2020 - July 30 -2020 at Grady Memorial Hospital, Atlanta, Georgia - a safety net hospital. We evaluated the association between mortality and demographics, co-morbidities, inpatient laboratory, and radiological parameters. RESULTS: Among 181 critically ill mechanically ventilated African American patients treated at a safety net hospital, the mortality rate was 33%. On stratified analysis by race (Table 2), mortality rates were significantly higher in African Americans (39%) and Hispanics (26.3%), compared to Whites (18.9%). On multivariate regression, African Americans were 3 times more likely to die in the ICU compared to Whites (OR 3.1 95% CI 1.6 -5.5). Likewise, the likelihood of mortality was higher in Hispanics compared to Whites (OR 1.3 95% CI 1.0 -3.9). CONCLUSIONS: Our study demonstrated a high ICU mortality rate in a cohort of mechanically ventilated patients with severe COVID-19 infection treated at a safety net hospital. African Americans and Hispanics had significantly higher risks of ICU mortality compared to Whites. These study findings further elucidate the disproportionately higher burden of COVID-19 infection in African Americans and Hispanics.

Intensive care unit hospitalizations and outcomes in patients with severe COVID-19 during summer and fall surges in Georgia.

BACKGROUND: There is limited data on the difference in the clinical characteristics and outcomes of patients with severe coronavirus disease 2019 (COVID-19) infection in the summer compared to the fall surge. AIM: To compare the sociodemographic, clinical characteristics, and outcomes among mechanically ventilated patients with severe COVID-19 infection admitted to the intensive care unit (ICU) during the summer and fall surges in the year 2020. METHODS: We included patients admitted to the ICU and treated with invasive mechanical ventilation for COVID-19 associated respiratory failure between April 1 and December 31, 2020. Patients were categorized into summer surge for ICU admissions between June 15, 2020, and August 15, 2020, and fall surge between October 15, 2020, and December 31, 2020. We compared patients' characteristics and outcomes using descriptive and inferential statistics. RESULTS: A total of 220 patients were admitted to the Grady Memorial Hospital ICU and mechanically ventilated for COVID-19 associated hypoxemic respiratory failure during the period considered (125 during the summer surge and 95 during the fall surge). More women were admitted in the fall compared to summer (41.1% vs 36.8%, difference, 4.3%; 95%CI: 1.2, 7.5). Patients admitted in the fall had fewer comorbidities (chronic obstructive pulmonary disease, stroke, diabetes mellitus, obstructive sleep apnea and body mass index ≥ 35 kg/m2). Overall, patients in the fall had a lower ICU mortality rate (27.4% vs 38.4%, difference, -11.0; 95%CI: -6.4, -18.2), shorter length of stay on the mechanical ventilator (7 d vs 11 d, difference, 4 d; 95%CI: 2.1, 6.6) and shorter ICU length of stay (9 d vs 14 d, difference, 5 d; 95%CI: 2.7, 9.4). CONCLUSION: Patients admitted with severe COVID-19 infection requiring mechanical ventilation had better outcomes in the fall than summer. This difference observed is likely attributable to a better understanding of the condition and advances in treatment strategies.

A Rare Triad: Hypercalcemia-Induced Necrotizing Pancreatitis Presenting as Severe Diabetic Ketoacidosis.

Primary hyperparathyroidism (PHPT) typically occurs in persons above 45 years, with a female predominance. PHPT induces a state of hypercalcemia, but acute pancreatitis is a rare sequelae of this hypercalcemia. We report a case of a 31-year-old man with no known medical history who presented in diabetic ketoacidosis with electrolyte abnormalities. His clinical course progressed to multi-organ dysfunction despite correction of metabolic derangements. Further workup led to the discovery of the uncommon triad by which previously undiagnosed PHPT precipitated severe diabetic ketoacidosis.

Rapid decline in ejection fraction and persistent elevation of troponin associated with cardiac amyloidosis.

Cardiac amyloidosis is an increasingly recognized cause of heart failure. It remains underdiagnosed despite a significant morbidity and mortality rate. The mean survival in patients with cardiac amyloidosis is less than 1 year in untreated primary light-chain amyloidosis and less than 4 years in wild-type transthyretin amyloidosis. We report a unique case of a 78-year-old male with transthyretin cardiac amyloidosis, who presented with persistently elevated troponin and progressive heart failure unresponsive to conventional therapy. With this case, we would like to highlight the role of cardiac biomarkers in the early diagnosis of cardiac amyloidosis.

Learning Styles of Internal Medicine Residents and Association With the In-Training Examination Performance.

INTRODUCTION: Assessment of how medical residents learn and the impact on standardized test performance is important for effective training. Kolb's learning study inventory categorizes learning into accommodating, assimilating, converging and diverging based on the four stages of learning: active experimentation, abstract conceptualization, concrete experience and reflective observation. The American College of Physicians (ACP) Internal Medicine In-Training Examination (IM-ITE) has been shown to positively correlate with successful performance on clinical assessments and board certification. We sought to evaluate the association between the individual learning styles of IM residents and performance on the ACP IM-ITE. METHODS: The Kolb LSI questionnaire was administered to IM residents during the 2016/2017 academic year. Logistic regression was used to analyze the association between residents preferred learning styles and performance on the ACP IM - ITE. RESULTS: 53 residents in the IM Residency Program of Morehouse School of Medicine completed the questionnaire. The predominant learning style was assimilating (49%), followed by converging (26%). There was no significant difference between the learning styles of residents when compared across gender, age, race, and PGY levels. Residents with a diverging learning style had the highest mean IM-ITE percentage score followed by assimilating and converging respectively (P = 0.14) CONCLUSIONS: The predominant learning styles among our IM residents are assimilating and converging, which is consistent with previous studies. Residents with a diverging style of learning appeared to perform better on the IM-ITE. We suggest that future studies should evaluate the feasibility of integrating brainstorming and group work sessions into the IM residency teaching curriculum and the impact on academic performance.

Factors influencing the uptake of influenza vaccination in African American patients with heart failure: Findings from a large urban public hospital.

BACKGROUND: Evidence suggests that annual influenza vaccination may prevent acute heart failure exacerbation episodes and improve survival. OBJECTIVE: Determine the influenza vaccination rate among African American patients with heart failure and identify predictors of uptake. METHODS: African American patients with heart failure were recruited at Grady Memorial Hospital, Atlanta GA between October 1, 2017 and April 28, 2018 (N = 281). All participants completed a questionnaire. RESULTS: Mean age of the sample was 50.5 ± 11.5 years (58% male). The influenza vaccination rate among the patients was 46% (n = 129/281). Patients who received vaccination information and recommendation from their physician, especially cardiologists, were significantly more likely to be vaccinated than those who did not (P<0.05). Major reasons for declining vaccination included fear of getting sick from influenza vaccine and distrust of the pharmaceutical companies that produce vaccines. CONCLUSIONS: Recommendation of influenza vaccines by physicians during medical consultations and cardiology visits may improve uptake rates in heart failure patients.

A Provocative Molecular Link between Mammographic Density and BRCA1-loss associated TNBC.

Triple-negative breast cancer (TNBC) is a highly aggressive form of breast cancer that has a high mortality rate and disproportionately affects young African American (AA) women who carry mutations in the BRCA1 gene. Approximately 80% of breast cancers which develop in BRCA1-mutant carriers will have TNBC and the molecular mechanism facilitating tumor development is unclear. Our earlier work suggested Ubc9 to play a critical role in BRCA1 loss mediated TNBC cell migration and metastasis. Collagen is one of the major components of the stromal extracellular matrix (ECM) network that influences tissue density. Its re-organization act as a scaffold aiding cancer cells to migrate causing metastasis. Ubc9 is known to increase the production of collagen, a key component of fibroglandular breast tissue, as well as tumorigenesis. Our work is based on the hypothesis that loss of BRCA1 in women with high breast density causes abnormal Ubc9 levels which upregulates collagen, fibronectin and inhibits SIRT1, ß-catenin expression facilitating TNBC. We tested this hypothesis by studying the expression of total collagen, fibronectin, Ubc9, SIRT1, ß-catenin in BRCA1 mutant TNBC cells and tumor sample derived from patient with dense breasts using immunofluorescence, immunohistochemistry, and collagen assay. Our results suggest for the first time that mutation or loss of BRCA1 function in women with fibrocystic breasts can lead to over expression of Ubc9, induction of collagen and; fibronectin, inhibition of SIRT1 and nuclear accumulation of ß-catenin which could contribute to TNBC development. This network will aid not only in the identification of potential mechanism-based biomarkers that could detect disease early, but also enforce preventive measures that could reduce the risk for TNBC in women with high MD thus reducing the mortality associated with these cancers to achieve health equity.
