Racial disparities in the incidence and survival outcomes in diffuse large B-cell lymphoma in adolescents and young adults.

Diffuse large B-cell Lymphoma (DLBCL) is an aggressive subtype of non-Hodgkin lymphoma (NHL). The disease generally occurs in older patients. Although at a lower prevalence, the disease also occurs in the adolescent and young adult group (AYA). There is paucity of data in the literature on racial and ethnic disparities in the incidence and survival outcomes of DLBCL in the AYA group. The objective of our study is to demonstrate the disparities in these outcomes. Utilizing SEER, we obtained data on patient demographics, incidence, and survival from 2000 to 2020. We observed statistically significant reduced incidence of DLBCL in all racial groups, except the non-Hispanic Asian and Pacific Islander group (NHAPI). The non-Hispanic Black group (NHB) had one of the lowest survival despite showing the largest decrease in incidence in DLBCL. The differences in the survival could be secondary to socioeconomic factors, however other reasons need to be explored. The increased incidence among the NHAPI group mirrors that of large population-based studies in East Asian countries, however, underlying reasons have not been elucidated.

Malignant Pleural Effusion Due to Uterine Serous Carcinoma: An Unusual Presentation.

Endometrial cancer is the most common cancer of the female genital tract. It can rarely metastasize to the pleura and present as a malignant pleural effusion. Here we present the case of a 61-year-old female with two primary malignancies, breast and endometrium, who presented to us with shortness of breath. Imaging was suggestive of a malignant pleural effusion. Diagnostic and therapeutic thoracentesis were performed that were initially suggestive of a breast source. However, final pleural fluid studies showed endometrial serous carcinoma as the source of the effusion. The patient received pembrolizumab and lenvatinib treatment and continues to be followed up in our clinic.

Assessment of Bleeding Risk in Hospitalized COVID-19 Patients: A Tertiary Hospital Experience during the Pandemic in a Predominant Minority Population-Bleeding Risk Factors in COVID-19 Patients.

Introduction: In the wake of the SARS-CoV-2 (COVID-19) pandemic, our world has faced multiple challenges. Infection with this virus has commonly been associated with thrombotic events. However, little is known about bleeding risk and anticoagulation therapy. This study aims to determine factors that are associated with increased risk of bleeding in COVID-19 patients. Methods: A retrospective cohort study was conducted using the records of COVID-19 patients admitted during the COVID-19 pandemic from March 2020 through May 2020. Using patient charts, investigators manually collected data regarding patient characteristics and bleeding. Patients were included in the analysis if they had a confirmed COVID-19 PCR test, were older than 18 years of age and were admitted to the hospital. Patients who were pregnant or had incomplete charts were excluded from the study. ANOVA and logistic regression were used to determine the statistical significance of the data using SPSS version 27. Results: A total of 651 patients were included in the analysis out of 685 patients located in the database of COVID-19 infected patients during that time frame. The general characteristics of the patients were as follows: 54.2% were males; females 45.8% ages ranged from 28 to 83 years old (median age = 66 years old). There were 31 patients (4.9%) who required more than 1 unit of packed red blood cell (PRBC). A total of 16 (2.85%) patients had a documented gastrointestinal bleed (GIB), of which 8 received a total of 29 units of PRBC transfusions. The HAS-BLED score (without alcohol/drug due to inadequate charting) is calculated for patients who had a documented GI bleed and who received more than one unit of PRBC. It was noted that the higher the HAS-BLED score the greater the likelihood of having a GI bleed (p < 0.001). The HAS-BLED score (not including alcohol/drug) was also predictive for patients who received more than one unit of PRBC during their hospital stay (p < 0.001). Discussion: Using the HAS-BLED score without alcohol/drugs, patients with COVID-19 can be stratified in regard to their risk of GI bleeding and their risk of transfusion while in the hospital. When administering anticoagulation therapy, cautious monitoring should be carried out. Decisions regarding anticoagulant therapy should be based on individual patient characteristics.

Chronic Eosinophilic Pneumonia Masquerading as a Lung Mass.

Lung masses are becoming more common, and although most are tumors, benign or malignant, some are not solid masses. Many pathologies can present as lung nodules, including lung cancers, hamartomas, lung abscesses, granulomas, and eosinophilic pneumonia, to name a few. A 40-year-old woman with a long history of smoking presented with cough and left-sided chest pain. After multiple imaging studies, she was thought to have a lung malignancy; however, multiple biopsies proved this was not the case. The histology reports of 3 to 4 biopsies at separate times indicated chronic inflammation ongoing in the lungs without any cancer cells present. She was treated for chronic eosinophilic pneumonia with a resolution of symptoms. The purpose of this case report is to discuss a case that was initially thought to be a lung mass but found to be chronic eosinophilic pneumonia manifesting as a lung mass.

High Incidence of Thrombotic Thrombocytopenic Purpura Exacerbation Rate Among Patients With Morbid Obesity and Drug Abuse.

This study aims to identify the baseline patient characteristics, clinical presentation, and response to treatment of 11 patients who were diagnosed with thrombotic thrombocytopenic purpura (TTP) between 2014 and 2020 at Brookdale University Hospital Medical Center, Brooklyn, NY. Laboratory and clinical parameters were recorded for 29 patients who received plasmapheresis in this time period. Of 29 patients, 11 had confirmed TTP and one was diagnosed with hereditary TTP. Young, black, and female patients made up the majority of our patient population. A high prevalence of obesity and drug abuse were seen among our patients. Five out of 11 were obese and four of them were morbidly obese; six out of 11 patients were positive for the drug screen including cannabinoids (3), opiates (2), benzodiazepines (1), PCP (1), and methadone (1). Four patients with a positive drug screen had acute kidney injury (AKI), and plasmapheresis helped them enhance their kidney function. We observed a high incidence of AKI and high TTP exacerbation rates in patients who were drug abusers and those who were morbidly obese. There is a paucity of data on the relationship of TTP with obesityor drug abuse and this needs further study.

Quality Improvement Project of a Massive Transfusion Protocol (MTP) to Reduce Wastage of Blood Components.

Massive transfusion protocols (MTPs) facilitate the organized delivery of blood components for traumatically injured patients. MTPs vary across institutions, and ratios of blood components can change during clinical management. As a result, significant amounts of components can be wasted. We completed a review of all MTP activations from 2015 to 2018, providing an in-depth analysis of waste in our single Level 1 trauma center. An interdepartmental group analyzed patterns of blood component wastage to guide three quality improvement initiatives. Specifically, we (1) completed a digital timeline for each MTP activation and termination, (2) improved communications between departments, and (3) provided yearly training for all personnel about MTP deployment. The analysis identified an association between delayed MTP deactivations and waste (RR = 1.48, CI 1.19-1.85, p = 0.0005). An overall improvement in waste was seen over the years, but this could not be attributed to increased closed-loop communication as determined by the proportion of non-stop activations (F(124,3) = 0.98, not significant). Delayed MTP deactivations are the primary determinant of blood component waste. Our proactive intervention on communications between groups was not sufficient in reducing the number of delayed deactivations. However, implementing a digital timeline and regular repetitive training yielded a significant reduction in wasted blood components.

Critical Review and Meta-Analysis of Postoperative Sedation after Adult Cardiac Surgery: Dexmedetomidine Versus Propofol.

OBJECTIVE: To evaluate reports from the published literature of all randomized clinical trials (RCT) comparing postoperative sedation with dexmedetomidine versus propofol in adult patients, after open cardiac surgery. DESIGN: A computerized search on Medline, EMBASE, Web of Science, and Agency for Healthcare Research and Quality databases was completed through June 2020. Meta-analysis of all published RCT comparing dexmedetomidine versus propofol utilization in the postoperative phase, using the standard Preferred Reporting Items for Systematic Reviews and Meta-Analyses checklist. SETTING: Assemblage and critical discussion of 11 RCTs comparing postoperative sedation from standard published reports from 2003 to 2019. PARTICIPANTS: The study comprised 1,184 patients and analyzed critical discussion of time-based parameters (time to extubation, intensive care unit length of stay, and hospital length of stay) and nontime-dependent factors (delirium, bradycardia, and hypotension). MEASUREMENTS AND MAIN RESULTS: Time to extubation was significantly reduced in the dexmedetomidine group (standardized mean difference [SMD] = -0.70, 95% confidence interval [CI] -0.98 to -0.42, p < 0.001); however, no difference in mechanical ventilation time was observed (SMD = -0.72, 95% CI -1.60 to 0.15, N.S.). Dexmedetomidine significantly reduced the intensive care unit length of stay (SMD = 0.23, 95% CI -1.06 to -0.16, p = 0.008), but this did not translate into a reduced hospital length of stay (SMD = -1.13, 95% CI -2.43 to 0.16, N.S). For nontime-dependent factors, incidence of delirium was unaffected between groups (odds ratio [OR]: 0.68, 95% CI 0.43-1.06, N.S), and higher rates of bradycardia (OR: 3.39, 95% CI: 1.20-9.55, p = 0.020) and hypotension (OR: 1.68, 95% CI 1.09-2.58, p = 0.017) were reported with propofol. CONCLUSIONS: Despite the ICU time advantages afforded by dexmedetomidine over propofol, the former did not seem to contribute to an overall reduction in hospital length of stay or improvement in postoperative outcomes of heart valve surgery and CABG patients.

Ivermectin: A Closer Look at a Potential Remedy.

Amid the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic, the search for effective treatment and vaccines has been exponentially on the rise. Finding effective treatment has been the core of attention of many scientific reports and antivirals are in the center of those treatments. Numerous antivirals are being studied for the management of the coronavirus disease 2019 (COVID-19) pneumonia caused by the SARS-CoV-2. Remdesivir was the first drug to gain emergency FDA approval to be used in COVID-19. Similarly, favipiravir, an anti-influenza drug, is being studied as a potential agent against COVID-19. Contrastingly, hydroxychloroquine has been a controversial drug in the management of COVID-19. Nevertheless, the National Institute of Health (NIH), along with the World Health Organization (WHO), have discontinued clinical trials for hydroxychloroquine as the drug showed little or no survival benefit. Ivermectin, an antihelminthic drug, has shown antiviral properties previously. Additionally, it was described to be effective in vivo against the SARS-CoV-2. However, its survival benefit in patients with COVID-19 has not been documented. We herein propose the theory of inhaled ivermectin which can attain the desired lung concentration that will render it effective against SARS-CoV-2.

Ethnic and Gender Disparities in the Uptake of Transcatheter Aortic Valve Replacement in the United States.

INTRODUCTION: Little is known about ethnic and gender disparities for transcatheter aortic valve replacement (TAVR) procedures in the United States. METHODS: We queried the Nationwide Inpatient Sample (NIS) database (2011-2014) to identify patients who underwent TAVR. We described the temporal trends in the uptake of TAVR procedures among various ethnicities and genders. RESULTS: Our analysis identified 39,253 records; 20,497 (52.2%) were men and 18,756 (47.8%) were women. Among all TAVRs, 87.2% were Caucasians, 3.9% were African Americans (AA), 3.7% were Hispanics, and 5.2% were of other ethnicities. We found a significant rise in the trend of TAVRs in all groups: in Caucasian men (coefficient = 0.946, p < 0.001), Caucasian women (coefficient = 0.985, p < 0.001), AA men (coefficient = 0.940, p < 0.001), AA women (coefficient = 0.864, p < 0.001), Hispanic men (coefficient = 0.812, p = 0.001), Hispanic women (coefficient = 0.845, p < 0.001). Hence, the uptrend was most significant among Caucasian women, and relatively least significant among Hispanic men. Multivariate regression analysis was conducted to evaluate in-hospital mortality among different groups after adjusting for demographics and baseline characteristics. After multivariable regression for baseline characteristics overall, the in-hospital mortality per 100 TAVRs was highest among Hispanic men 5.5%, followed by Caucasian women 5.0%, Hispanic women 4.6%, AA women 3.7%, AA men 3.4%, and Caucasian men 3.38% (adjusted p value = 0.004). CONCLUSIONS: In this observational study, we demonstrated that there is evidence of ethnic and gender differences in the overall uptake and adjusted mortality of TAVRs in the United States.

Meta-Analysis of Trials on Prophylactic Use of Levosimendan in Patients Undergoing Cardiac Surgery.

BACKGROUND: The role of prophylactic levosimendan in patients undergoing cardiac surgery is controversial. METHODS: We performed a computerized search of Medline, Embase, and Cochrane databases through September 2017 for randomized trials evaluating the prophylactic use of levosimendan in patients undergoing cardiac surgery (ie, patients without low cardiac output syndrome). The main study outcome was mortality at 30 days. RESULTS: The final analysis included 16 randomized trials with total of 2,273 patients. There was no statistically significant difference in mortality at 30 days between levosimendan and control groups (relative risk 0.68, 95% confidence interval [CI]: 0.45 to 1.03). Subgroup analysis showed no statistically significant difference in mortality at 30 days for patients with reduced left ventricular ejection fraction compared with patients having preserved left ventricular ejection fraction (p for interaction = 0.12). Further analysis suggested that levosimendan might be associated with improved mortality at 30 days when compared with active-control but not when compared with placebo (p for interaction = 0.01). The levosimendan group had a significant reduction in acute kidney injury (relative risk 0.59, 95% CI: 0.38 to 0.92), intensive care unit stay (standardized mean difference = -0.21, 95% CI: -0.29 to -0.13), and ventilation time (standardized mean difference = -0.43, 95% CI: -0.61 to -0.25), whereas it had higher rates of atrial fibrillation (relative risk 1.11, 95% CI: 1.00 to 1.24). No statistically significant differences were observed between groups in mortality beyond 30 days, postoperative dialysis, or myocardial infarction. CONCLUSIONS: Prophylactic use of levosimendan does not appear to reduce the mortality at 30 days or beyond 30 days in patients undergoing cardiac surgery. This lack of benefit was noted irrespective of the LVEF.
