Neurovascular anatomy of dwarf dinosaur implies precociality in sauropods.

Macronaria, a group of mostly colossal sauropod dinosaurs, comprised the largest terrestrial vertebrates of Earth's history. However, some of the smallest sauropods belong to this group as well. The Late Jurassic macronarian island dwarf is one of the most peculiar and best-studied sauropods worldwide.

Health Care Workers' Sick Leave due to COVID-19 Vaccination in Context With SARS-CoV-2 Infection and Quarantine-A Multicenter Cross-Sectional Survey.

Background: Reactogenicity of coronavirus disease 2019 (COVID-19) vaccines can result in inability to work. The object of this study was to evaluate health care workers' sick leave after COVID-19 vaccination and to compare it with sick leave due to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and quarantine leave.

Methods: A multicenter cross-sectional survey was conducted at Regensburg University Medical Center and 10 teaching hospitals in South-East Germany from July 28 to October 15, 2021.

Risk to Radiology Staff for Occupational COVID-19 Infection in a High-Risk and a Low-Risk Region in Germany: Lessons from the "First Wave".

Purpose: The recent COVID-19 pandemic has resulted in an increasing overload of the medical system. Healthcare workers (HCW) in radiology departments are exposed to a high infection risk similar to HCWs in the ICU or dedicated COVID wards. The goal of our paper is to evaluate the prevalence of IgG antibody against SARS-CoV-2 among radiology HCWs in two different hospitals and regions in Germany with a low and high COVID-19 prevalence and to compare it to the prevalence in other clinical personnel.

[SARS-CoV-2 antibodies in ICU and clinic staff : From Germany's region with the highest infection rate].

Background: Healthcare workers are a high-risk population for SARS-CoV‑2 infection. For capacity planning of healthcare providers and to optimize protection of healthcare workers (HCW) in SARS-CoV‑2 pandemics, it is essential to know the risk of infection and potential immunity status of staff dealing with COVID-19 patients.

Materials And Methods: We examined seropravalence of SARS-CoV‑2 IgM/IgG antibodies (AB) in HCW of a region with the highest rate of infection (1570/100,000) during COVID-19 pandemic in Germany, 4 months after its start.

The 24-Month Results of the Lutonix Global SFA Registry: Worldwide Experience With Lutonix Drug-Coated Balloon.

Objectives: The Global SFA Registry sought to assess safety, clinical benefit, and outcomes of the Lutonix 035 drug-coated balloon (DCB) in a heterogeneous, real-world patient population at 12 and 24 months.

Background: Numerous clinical studies have evaluated the use of angioplasty for revascularization of femoropopliteal arteries in peripheral arterial disease with restenosis rates of 40% to 60% at 6 to 12 months. Data from recent studies document decreased restenosis rates and improvement in patency in patients receiving angioplasty of femoropopliteal arteries with DCBs.
