Lung ultrasonography performed by nephrologist: COVID-19 as an opportunity to reveal ultrasound's full potential and usefulness in the dialysis room.

Background: Interest in point-of-care ultrasound (POCUS) and lung ultrasound (LUS) is growing in the nephrology and dialysis field, and the number of nephrologists skilled in what is proving to be the "5th pillar of bedside physical examination" is increasing. Patients on hemodialysis (HD) are at high risk of contracting severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) and developing coronavirus disease 2019 (COVID-19) serious complications. Despite this, to our knowledge there are no studies to date that show the role of LUS in this setting, while there are many in the emergency room, where LUS proved to be an important tool, providing risk stratification and guiding management strategies and resource allocation.

[COVID-19 recurrence due to reinfection with SARS-CoV-2 in a hemodialysis patient: there and back again].

The COVID-19 pandemic has caused millions of infections and deaths so far. After recovery, the possibility of reinfection has been reported. Patients on hemodialysis are at high risk of contracting SARS-CoV-2 and developing serious complications.

Increase of continuous treatments and regional citrate anticoagulation during renal replacement therapy in the ICUs of the North-West of Italy from 2007 to 2015.

Background: Few reports have addressed the change in renal replacement therapy (RRT) management in the Intensive care Units (ICUs) over the years in western countries. This study aims to assess the trend of dialytic practice in a 4.5-million population-based study of the northwest of Italy.

[Severe hyperkalemia in patients referred to an emergency departement: the role of antialdosterone drugs and of renin-angiotensin system blockers].

We analyzed the clinical features and the factors associated with the presence of hyperkalemia (serum potassium >5.3 mmol/L) in a cohort of patients presenting to an Emergency Department. A total of 168 cases were observed (89 males and 79 females), mean age 77.

Hemodynamic response to coupled plasmafiltration-adsorption in human septic shock.

Objective: The objective was to examine the effect of repeated applications of coupled plasmafiltration-adsorption on the hemodynamic response in septic shock patients hospitalized in intensive care units (ICUs).

Design: Prospective, intention-to-treat.

Setting: General ICU of a tertiary care, non-teaching, 400-bed, city hospital.
