We assessed the incidence of deep vein thrombosis (DVT) and pulmonary embolism (PE) in hospitalized patients with coronavirus disease 2019 (COVID-19) compared with that in a matched cohort with similar cardiovascular risk factors and the effects of DVT and PE on the hospital course.

We performed a retrospective review of prospectively collected data from COVID-19 patients who had been hospitalized from March 11, 2020 to September 4, 2020. The patients were randomly matched in a 11 ratio by age, sex, hospital of admission, smoking history, diabetes mellitus, and coronary artery disease with a cohort of patients without COVID-19. The primary endpoint was the incidence of DVT/PE and the odds of developing DVT/PE using a conditional logistic regression model. The secondary endpoint was the hospitalization outcomes for COVID-19 patients with and without DVT/PE, including mortality, intensive care unit (ICU) admission, ICU stay, and length of hospitalization (LOH). Multivariable regression analysis was performe COVID-19-positive patients compared with a non-COVID-19 cohort matched for cardiovascular risk factors. Patients affected by DVT/PE were more likely to experience greater mortality, to require ICU admission, and experience prolonged ICU stays and LOH compared with COVID-19-positive patients without DVT/PE. Advancements in DVT/PE prevention are needed for patients hospitalized for COVID-19 infection.
A significantly greater incidence of DVT/PE occurred in hospitalized COVID-19-positive patients compared with a non-COVID-19 cohort matched for cardiovascular risk factors.

Histologic analyses of deep vein thrombi (DVTs) have used autopsy samples and animal models. To the best of our knowledge, no previous study has reported on thrombus composition after percutaneous mechanical extraction. Because elements of chronicity and organization render thrombus resistant to anticoagulation and thrombolysis, a better understanding of clot evolution could inform therapy.

We performed a histologic evaluation of DVTs from consecutive patients who had undergone mechanical thrombectomy for extensive iliofemoral DVTs using the Clottriever/Flowtriever device (Inari Medical, Irvine, Calif). The DVTs were scored using a semiquantitative method according to the degree of fibrosis (collagen deposition on trichrome staining) and organization (endothelial growth with capillaries and fibroblastic penetration).

Twenty-three specimens were available for analysis, with 20 presenting as acute DVT (≤14days from symptom onset). Of the 23 patients, 11 (48%) had had >5% fibrosis (ie, collagen deposition) and 14 (61%) had had >5% organization (ie, endothelial growth, capillaries, fibroblasts). Four patients with acute DVT had had ≥25% organized thrombus and two had had ≥25% collagen deposition. Of the 20 patients with acute DVT, 40% had had >5% fibrosis and 55% had had >5% organization. The acuity of DVT did not correlate with the amount of fibrosis or organizing scores.

A large proportion of patients with acute DVT will have histologic elements of chronicity and fibrosis. Selleck GSH A better understanding of the relationship between such elements and the response to anticoagulant agents and fibrinolytic drugs could inform our approach to therapy.

Recently, sirolimus has emerged as a safe and effective treatment modality for unresectable vascular lesions. In the present study, we investigated the effectiveness and safety of sirolimus from our early experience with patients with unresectable vascular anomalies.

The medical records and radiologic images of all patients with unresectable vascular anomalies treated with sirolimus at our center from January 2018 to November 2019 were retrospectively reviewed. All patients were administered oral doses of sirolimus 0.8mg/m
every 12hours as the initial dose, followed by maintenance of a target serum concentration (5-10ng/mL) with therapeutic drug monitoring.

Six patients with unresectable vascular anomalies were treated with sirolimus for ≥10months. Their median age at the initiation of sirolimus treatment was 17months (range, 8-67months). The median duration of treatment was 13months (range, 10-16months). One patient had a good response, four had an intermediate response, and one had no response to sirolimus therapy. None of the patients had discontinued sirolimus therapy because of adverse effects.

Sirolimus can be used effectively and safely for patients with unresectable vascular anomalies. However, further prospective studies are warranted to evaluate the long-term effects of sirolimus and clarify the indications for early intervention.

Between 2015 and 2017, nearly 80,000 hospital stays in orthopaedic surgery were entered into a home discharge support programme (PRADO) offered by the statutory health insurance system. The objective of this study was to assess the impact of the PRADO programme on enrolled stays in orthopaedic surgery over the last three years.

The home discharge support programme used in orthopaedic surgery shortens hospital stays and decreases the rate of readmission within 30days.

The home discharge support programme PRADO was evaluated both quantitatively and qualitatively. The quantitative study used a multicentre retrospective cohort design with matching to controls identified in the national healthcare database. All hospital stays entered into the home discharge support programme between January 2015 and December 2017 were enrolled in the study. Follow-up was 6months after discharge. The main outcome measure was the rate of readmission within 30days after discharge. The secondary outcome measures were emergency department visits, admission to rehabilitation, mean stay duration, visits to recommended healthcare professionals, medication consumption, and total healthcare expenditure at 6months.
