Do hospitals that participate in COVID-19 research differ from non-trial hospitals? A cross-sectional study of US hospitals.

Objectives: To compare hospitals that did and did not participate in clinical trials evaluating potential inpatient COVID-19 therapeutics.

Methods: We conducted a cross-sectional study of hospitals participating in trials that were registered on clinicaltrials.gov between April and August 2020.

Tricuspid Valve Nonbacterial Thrombotic Endocarditis in a Patient with Metastatic Pulmonary Malignancy.

Nonbacterial thrombotic endocarditis (NBTE) is a pathologic state associated with autoimmune diseases and malignancy in which platelet thrombi are deposited on the heart valves in the absence of a bloodstream infection. NBTE is a diagnosis of exclusion that requires a high degree of clinical suspicion after infective endocarditis etiologies have been ruled out. The treatment of NBTE consists of systemic anticoagulation, with direct oral anticoagulants and surgery not having a clear role.

Percutaneous thermal ablation of subcapsular hepatocellular carcinomas: influence of tumor-surface contact and protrusion on therapeutic efficacy and safety.

Purpose: To evaluate therapeutic efficacy and complication of percutaneous thermal ablation of subcapsular hepatocellular carcinomas (HCCs), and how these may be influenced by the degree of tumor to liver surface contact and tumor protrusion from liver surface.

Materials And Methods: Our retrospective study was approved by the Institutional Review Board. Between January 2006 and December 2013, 290 patients (82 women, 208 men; mean age, 64.

Impact of Hypothyroidism and Heart Failure on Hospitalization Risk.

Background: Prior studies suggest that the relationship between hypothyroidism and mortality is dependent on underlying cardiovascular risk. Little is known about the association of hypothyroidism with hospitalization risk, and how these associations are modified by cardiovascular status.

Methods: This study examined the association of thyroid status, defined by serum thyrotropin (TSH), with hospitalization risk among patients who received care at a large university-based tertiary care center between 1990 and 2015.

Factors Associated With Discordance Between Preoperative Parathyroid 4-Dimensional Computed Tomographic Scans and Intraoperative Findings During Parathyroidectomy.

Importance: Parathyroid 4-dimensional computed tomographic scans (4D-CTs) have emerged as an accurate and cost-effective initial localization study for patients with primary hyperparathyroidism. However, potential limitations and factors affecting the accuracy of preoperative 4D-CTs remain poorly defined.

Objectives: To characterize factors associated with missed parathyroid lesions on preoperative 4D-CTs and to investigate patterns of commonly observed errors.
