A Safe Approach to Percutaneous Tracheostomy for COVID-19 Patients in Intensive Care.

The novel coronavirus disease 2019 (COVID-19) has placed a burden on critical care facilities worldwide. Patients who remain critically unwell with COVID-19 require prolonged periods of ventilation, and the burden of both the resources during a pandemic and the slow respiratory wean must be managed. Percutaneous tracheostomies are commonplace in long-term intensive care patients, yet little is known about their role in COVID-19, particularly how operator safety is maintained during the procedure.

Bimodal Expansion of the Lymphatic Vessels Is Regulated by the Sequential Expression of IL-7 and Lymphotoxin α1β2 in Newly Formed Tertiary Lymphoid Structures.

Lymphangiogenesis associated with tertiary lymphoid structure (TLS) has been reported in numerous studies. However, the kinetics and dynamic changes occurring to the lymphatic vascular network during TLS development have not been studied. Using a viral-induced, resolving model of TLS formation in the salivary glands of adult mice we demonstrate that the expansion of the lymphatic vascular network is tightly regulated.

Aspirex Thrombectomy in Occluded Dialysis Access: A Retrospective Study.

Purpose: This study is the first to present the outcomes of the Straub Aspirex device for the salvage of occluded renal dialysis access fistulae.

Materials And Methods: This is a retrospective study, using data from the Renal Unit and Radiology Department database. It included all the patients between 2010 and 2014 who underwent percutaneous mechanical thrombectomy (PMT) treated by JD.
