Closure Device Use for Common Femoral Artery Antegrade Access is Higher Risk than Retrograde Access.

Ann Vasc Surg 2021 Apr 7. Epub 2021 Apr 7.

Department of Surgery, Division of Vascular and Endovascular Surgery, University of California, San Francisco, San Francisco, CA, USA.

Objective: Although the use of closure devices (CD) for femoral artery antegrade access (AA) is not in the instructions for use (IFU) for many devices, AA has been reported to be associated with a lower incidence of access site complications compared to manual compression alone. We hypothesized that CD use for AA would not be associated with a clinically significant increased odds of access site complications compared to CD use for retrograde access (RA).

Methods: This was a retrospective review of the Vascular Quality Initiative from 2010 to 2019 for infrainguinal peripheral vascular interventions with common femoral artery access closed with a CD. Read More

Characterisation of cardiac pathology in 23 autopsies of lethal COVID-19.

J Pathol Clin Res 2021 Apr 9. Epub 2021 Apr 9.

Pathology, Institute of Medical Genetics and Pathology, University Hospital Basel, University of Basel, Basel, Switzerland.

While coronavirus disease 2019 (COVID-19) primarily affects the respiratory tract, pathophysiological changes of the cardiovascular system remain to be elucidated. We performed a retrospective cardiopathological analysis of the heart and vasculature from 23 autopsies of COVID-19 patients, comparing the findings with control tissue. Myocardium from autopsies of COVID-19 patients was categorised into severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) positive (n = 14) or negative (n = 9) based on the presence of viral RNA as determined by reverse transcriptase polymerase chain reaction (RT-PCR).

Eur J Neurol 2021 Apr 9. Epub 2021 Apr 9.

Second Department of Neurology, "Attikon" University Hospital, School of Medicine, National and Kapodistrian University of Athens, Athens, Greece.

Background: Mounting evidence supports an association between Guillain-Barré syndrome spectrum (GBSs) and severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection. However, GBSs in the setting of coronavirus disease-2019 (COVID-19) remains poorly characterized, while GBSs prevalence among COVID-19 patients has not been previously systematically evaluated using a meta-analytical approach.

Methods: We performed a systematic review and meta-analysis of observational cohort and case-series studies reporting on the occurrence, clinical characteristics and outcomes of patients with COVID-19-associated GBSs. Read More

IL-6 modulation for COVID-19: the right patients at the right time?

J Immunother Cancer 2021 Apr;9(4)

Institute of Immunology and the CAS Key Laboratory of Innate Immunity and Chronic Disease, School of Life Science and Medical Center; Department of Pathology, The First Affiliated Hospital of USTC, Division of Life Sciences and Medicine, University of Science and Technology of China, Hefei, China.

The ongoing pandemic caused by the novel coronavirus SARS-CoV-2 has disrupted the global economy and strained healthcare systems to their limits. After the virus first emerged in late 2019, the first intervention that demonstrated significant reductions in mortality for severe COVID-19 in large-scale trials was corticosteroids. Additional options that may reduce the burden on the healthcare system by reducing the number of patients requiring intensive care unit support are desperately needed, yet no therapy has conclusively established benefit in randomized studies for the management of moderate or mild cases of disease.

Effects of angiotensin II receptor blocker usage on viral load, antibody dynamics, and transcriptional characteristics among COVID-19 patients with hypertension.

J Zhejiang Univ Sci B 2021 Apr;22(4):330-340

Department of Laboratory Medicine, the First Affiliated Hospital, Zhejiang University School of Medicine, Hangzhou 310003, China.

Epidemiological evidence suggests that patients with hypertension infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are at increased risk of acute lung injury. However, it is still not clear whether this increased risk is related to the usage of renin-angiotensin system (RAS) blockers. We collected medical records of coronavirus disease 2019 (COVID-19) patients from the First Affiliated Hospital, Zhejiang University School of Medicine (Hangzhou, China), and evaluated the potential impact of an angiotensin II receptor blocker (ARB) on the clinical outcomes of COVID-19 patients with hypertension.
