Esophageal squamous papilloma: Literature review and case-control retrospective study with histopathological exam of human papillomavirus.

Background and Aim: Esophageal squamous papilloma (ESP) is a benign growth in the esophagus with unknown malignant potential. The mechanism underlying ESP formation is unknown, but human papillomavirus (HPV) infection has been proposed as a potential etiology. We sought to investigate the clinical characteristic of ESP in our population, review the current literature, and highlight the role of HPV. Methods: This is a retrospective case-control study conducted at two referral centers. We selected the ESP population by free-text search in the pathology department database and selected controls randomly from the general endoscopy population. Immunostains were used to evaluate ESP tissue for HPV. Results: Between January 2016 and December 2021, we identified 66 patients with ESP, with a prevalence of 0.72%. ESP patients were younger, with a median age of 52 years (P = 0.021), and more likely African American (34.4 vs 7.5%, P < 0.001) compared to controls. On endoscopy images, the growth was predominantly solitary (92.5%) in the middle of the esophagus (39.4%), with sizes ranging from 0.2 to 2.3 cm. A total of 62 patients had available tissue for HPV immune staining, and none tested positive for HPV. Eighteen patients had a follow-up endoscopy with an average of 504.5 days follow-up period. One patient developed esophageal squamous cell carcinoma during follow-up. Conclusions: We observed a higher prevalence of ESP compared to previous studies. The formation of ESP is multifactorial and partially explained by HPV infection in selected populations. The malignant potential of ESP is low but not negligible.

Cardiovascular Safety of the COVID-19 Vaccine in Team USA Athletes.

BACKGROUND: Despite reassuring scientific data, the lay press and social media continue to propagate largely unsubstantiated claims that a significant number of athletes have died from cardiovascular complications related to COVID-19 vaccines. The present study sought to determine the incidence of COVID-19 vaccine cardiovascular complications in Team USA athletes. HYPOTHESIS: It was predicted that there would be a low incidence of cardiovascular complications from COVID-19 vaccination in Team USA athletes. STUDY DESIGN: Descriptive epidemiology study. LEVEL OF EVIDENCE: Level 4. METHODS: A retrospective review was conducted on the United States Olympic and Paralympic Committee electronic medical record, inclusive of athletes who represented Team USA in the 2020 Tokyo and 2022 Beijing Olympic and Paralympic Games, for COVID-19 vaccine cardiac complications including sudden cardiac arrest/death, myocarditis, pericarditis, and myopericarditis. Vaccination status (ie, fully vaccinated, yes or no), date of vaccination and eligible boosters, and type of vaccination during the study period were abstracted from the electronic medical record. RESULTS: A total of 1229 athletes represented Team USA during the 2020 Tokyo (Olympic, 697; Paralympic, 237) and 2022 Beijing Games (Olympic, 229; Paralympic, 66). For the 2020 Tokyo Games, 73.8% of Olympians and 80.6% of Paralympians with available vaccination status had completed a primary vaccine series. For the 2022 Beijing Games, 100% of Olympians and Paralympians with available vaccination status were fully vaccinated. No athletes suffered sudden cardiac arrest/death or were diagnosed with myocarditis, pericarditis, or myopericarditis after COVID-19 vaccination. CONCLUSION: The data demonstrate an overall willingness of elite athletes to receive recommended COVID-19 vaccination coupled with a complete absence of vaccine-related cardiac complications in >1 year of follow-up. CLINICAL RELEVANCE: Supposedly, this is the first study to investigate the incidence of COVID-19 vaccine cardiovascular complications in elite athletes. These data are an important first step to better inform cardiologists and sports medicine physicians who care for elite athletes.

Meningioma resection and venous thromboembolism incidence, management, and outcomes.

Background: Meningioma resection is associated with the risk of venous thromboembolism (VTE). Objectives: To determine the incidence and risk factors for VTE following meningioma resection and VTE outcomes based on the type and timing of anticoagulation. Methods: From 2011 to 2019, 901 consecutive patients underwent meningioma resection. We retrospectively evaluated the postoperative incidence of VTE and bleeding. For VTE, we determined the treatment strategy and rate of VTE complications and bleeding. Results: Pharmacologic prophylaxis was administered to 665 (73.8%) patients. The cumulative incidence for total postoperative VTE was 8.7% (95% CI: 6.9%-10.6%), and for symptomatic VTE was 6.0% (95% CI: 4.6%-7.7%). A multivariable model identified the following independent predictors of symptomatic VTE: history of VTE, obesity, and lack of pharmacologic prophylaxis. Following postoperative VTE, 58 (74.3%) patients received therapeutic anticoagulation either initially (33.3%) or after a median delay of 23.5 days (41.0%). Symptomatic recurrent VTE occurred in 13 (16.6%) patients. Following VTE, the use of subtherapeutic anticoagulation was associated with a lower rate of total VTE extension than no anticoagulation (17.5% vs 42.9%, OR 0.28, 95% CI: 0.09-0.93). In total, 14 patients (1.6%) experienced clinically relevant bleeding: 4 received therapeutic anticoagulants, 8 received prophylactic anticoagulation, and 2 received no anticoagulation. Among patients with VTE, 4 (5.1%) experienced bleeding. Conclusion: Recognition of risk factors for VTE following meningioma resection may help improve approaches to thromboprophylaxis. The management of postoperative VTE is highly variable, but most VTE patients are ultimately treated with therapeutic anticoagulants.

Impact of Atrial Fibrillation on In-Hospital Mortality and Stroke in Acute Aortic Syndromes.

BACKGROUND: Acute aortic syndromes may present with a number of cardiovascular complications, including atrial fibrillation. We assessed the prevalence of atrial fibrillation in patients presenting with acute aortic syndromes and evaluated atrial fibrillation's association with in-hospital mortality and stroke. METHODS: Consecutive patients with acute aortic syndromes admitted to a single tertiary care center from January 2015 to March 2020 were included. We identified patients with atrial fibrillation on the presenting electrocardiogram. RESULTS: A total of 309 patients with acute aortic syndromes were included in our analyses: 148 (48%) presented with Stanford type A and 161 (52%) with Stanford type B acute aortic syndromes. Twenty-seven (8.7%) patients had atrial fibrillation on the presenting electrocardiogram: 12 (44%) with type A and 15 (56%) with type B acute aortic syndromes. Patients with atrial fibrillation were older, more likely to be white, had a higher frequency of history of cancer, peripheral artery disease, cerebrovascular disease, and heart failure with preserved ejection fraction, compared with those without atrial fibrillation. Acute aortic syndromes patients with atrial fibrillation had higher frequencies of in-hospital mortality compared with those without atrial fibrillation (40.7% vs 12.4%, P < .0001). However, stroke frequencies did not differ between the 2 groups. CONCLUSION: In patients presenting with acute aortic syndromes and atrial fibrillation, we observed higher frequencies of in-hospital mortality, without differences in the frequencies of stroke.

Registry of Arterial and Venous Thromboembolic Complications in Patients With COVID-19.

BACKGROUND: Cardiovascular complications, including myocardial infarction, ischemic stroke, and pulmonary embolism, represent an important source of adverse outcomes in coronavirus disease-2019 (COVID-19). OBJECTIVES: To assess the frequency of arterial and venous thromboembolic disease, risk factors, prevention and management patterns, and outcomes in patients with COVID-19, the authors designed a multicenter, observational cohort study. METHODS: We analyzed a retrospective cohort of 1,114 patients with COVID-19 diagnosed through our Mass General Brigham integrated health network. The total cohort was analyzed by site of care: intensive care (n = 170); hospitalized nonintensive care (n = 229); and outpatient (n = 715). The primary study outcome was a composite of adjudicated major arterial or venous thromboembolism. RESULTS: Patients with COVID-19 were 22.3% Hispanic/Latinx and 44.2% non-White. Cardiovascular risk factors of hypertension (35.8%), hyperlipidemia (28.6%), and diabetes (18.0%) were common. Prophylactic anticoagulation was prescribed in 89.4% of patients with COVID-19 in the intensive care cohort and 84.7% of those in the hospitalized nonintensive care setting. Frequencies of major arterial or venous thromboembolism, major cardiovascular adverse events, and symptomatic venous thromboembolism were highest in the intensive care cohort (35.3%, 45.9%, and 27.0 %, respectively) followed by the hospitalized nonintensive care cohort (2.6%, 6.1%, and 2.2%, respectively) and the outpatient cohort (0% for all). CONCLUSIONS: Major arterial or venous thromboembolism, major adverse cardiovascular events, and symptomatic venous thromboembolism occurred with high frequency in patients with COVID-19, especially in the intensive care setting, despite a high utilization rate of thromboprophylaxis.
