Proximalization of arterial inflow with adjunctive arterial pressure measurements for management of hemodialysis access-induced distal ischemia.

Hemodialysis access-induced distal ischemia () is an uncommon, yet potentially devastating, complication of hemodialysis access surgery. Management of HAIDI depends on the access' volume flow and may involve banding, proximalization of arterial inflow, revision using distal inflow, distal revascularization interval ligation, or access ligation. Various adjunctive techniques have been used to confirm improved distal arterial flow intraoperatively.

Working nurses' empathy with patients in public hospitals.

Objective: to determine the levels of empathy in professional nurses of a high-complexity hospital, to relate age to empathy (and each one of its dimensions), and to establish if there are differences between these levels according to the type of working schedules.

Method: comparative, correlational and cross-sectional design. The sample used (n=271) constituted 40.

An Artificial Placenta Experimental System in Sheep: Critical Issues for Successful Transition and Survival up to One Week.

Objective: To describe the development of an artificial placenta (AP) system in sheep with learning curve and main bottlenecks to allow survival up to one week.

Methods: A total of 28 fetal sheep were transferred to an AP system at 110-115 days of gestation. The survival goal in the AP system was increased progressively in three consecutive study groups: 1-3 h (n = 8), 4-24 h (n = 10) and 48-168 h (n = 10).

Analysis of Presentation and Outcomes in Acute Limb Ischemia Patients During COVID-19 State of Emergency.

Background: During the COVID-19 pandemic, cardiovascular patients were found to be presenting to hospitals with myocardial infarctions and cerebrovascular accidents at progressed disease states. We noticed a parallel in acute limb ischemia (ALI) patients presenting during Massachusetts' COVID-19 State of Emergency declaration. We question whether patients developed a hesitancy to seek medical attention at hospitals due to fear of COVID-19.

A Flat Inferior Vena Cava on Computed Tomography Is Associated With Worse Outcomes in Emergency General Surgery.

Background: Several trauma studies have shown that a "flat" inferior vena cava (IVC) is associated with poor clinical outcomes, including hypovolemic shock, major bleeding, transfusions and mortality. These studies utilize IVC measurements on computed tomography (CT) scans, and rarely include emergency general surgery patients. We examine the association between IVC flatness and clinical outcomes in a series of patients with perforated viscus.
