Endovascularly retrieved clots may be a potential resource for diagnosing stroke etiology. This method may influence secondary prevention treatment. We measure thrombin activity eluted by serially washing clots. We concluded that an assay measuring the change in thrombin in clots retrieved during acute stroke endovascular thrombectomy procedures may serve as a diagnostic marker of the origin of the clot. The suggested mechanism for these differences may be the clot location before its retrieval, with high blood flow causing thrombin washout in atherosclerotic clots, in contrast to atrium appendage low blood flow retaining high thrombin levels.

Background: Sheba Medical Center, Tel Hashomer, is a tertiary hospital located in the center of Israel. It is the largest hospital in Israel and was the first to face coronavirus disease-2019 (COVID-19) patients in the country at the beginning of the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) pandemic.

Objectives: To describe our experience with the COVID-19 pandemic, focusing on our triage method in the emergency department (ED). Our goal was to keep the main hospitalization buildings clean of infection by separating COVID-19 positive patients from COVID-19 negative patients.

Methods: We divided our ED into two separate sections: a regular non-COVID-19 ED and an advanced biological ED. We created clear protocols of triage for suspected and confirmed COVID-19 patients. We reviewed the data of patients admitted to our ED during the month of March and analyzed the results of our triage method in separating COVID-19 positive from negative patients.

Results: During the month of March 2020, 7957 patients were referred to our ED. Among them 2004 were referred to the biological ED and 5953 were referred to the regular ED. Of the 2004 patients referred to the biological ED, 1641 (81.8%) were sampled for SARS-CoV-2 polymerase chain reaction of whom 143 (8.7%) were positive. Only two COVID-19 positive patients unintentionally entered the main clean hospital, making our triage almost full proof.

Conclusions: Our triage method was successful in separating COVID-19 positive from negative patients and maintained the regular hospital clean of COVID-19 allowing treatment continuation of regular non-COVID-19 patients.

Abstract

Video surveillance is a tool for managing safety and security within public spaces. In mental health facilities, the major benefit of video surveillance is that it enables 24 hour monitoring of patients, which has the potential to reduce violent and aggressive behavior. The major disadvantage is that such observation is by nature intrusive. It diminishes privacy, a factor of huge importance for psychiatric inpatients. Thus, an ongoing debate has developed following the increasing use of cameras in this setting. This article presents the experience of a medium-large academic state hospital using video surveillance, and explores the various ethical and administrative aspects of video surveillance in mental health facilities. 

Objectives: To examine the effect of meloxicam, a selective COX-2 inhibitor, or low dose aspirin on the development of experimental atherosclerosis in apoE knockout (KO) compared to wild-type (WT) mice. We aimed to test the hypothesis that meloxicam, a potential vasculitis inducer, would exacerbate atherosclerotic lesions while aspirin, which is known to reduce the incidence of thrombosis occlusive events, would increase protection in this model.

Methods: We randomly divided 36 male apoE KO and 36 WT mice, 8 weeks old. Mice were treated for 10 weeks with 0.1 mg/ml aspirin, or 0.05 mg/ml meloxicam, dissolved in their drinking water. Control groups received regular drinking water. At sacrifice, the hearts were removed for histochemical staining and plaque size and composition were examined.

Results: Aspirin-treated animals displayed a decreased atherosclerotic lesion area compared to the untreated control mice, while meloxicam had a null effect on the extent of atherosclerosis in Apo E KO mice.

Conclusions: These results suggest that low dose aspirin reduces early atherosclerosis, while inhibition of COX-2 by meloxicam is not associated with an increase in atherosclerotic plaque size in this mouse model.
