[Utility of computerized vascular access monitoring: a pilot study].

The surveillance of a vascular access (VA) is of primary importance for its outcome and for the patients' survival. However, there is still confusion about its usefulness, who should make it (physician or nurse) and when, and what is the best functional test to use. This retrospective analysis reports our experience of VA monitoring; it is based on the collaboration between concept doctors and nurses and on parameters integration, realized with the help of a software for vascular access monitoring (SMAV) designed by us.

[Covid-19 in patients on dialysis: infection prevention and control strategies].

Covid-19 is a disease caused by a new coronavirus presenting a variability of flu-like symptoms including fever, cough, myalgia and fatigue; in severe cases, patients develop pneumonia, acute respiratory distress syndrome, sepsis and septic shock, that can result in their death. This infection, which was declared a global epidemic by the World Health Organization, is particularly dangerous for dialysis patients, as they are frail and more vulnerable to infections due to the overlap of multiple pathologies. In patients with full-blown symptoms, there is a renal impairment of various degrees in 100% of the subjects observed.

[The ambiguous concept of predialysis: proposal for a model].

In 2009, 90% of nephrology centers in Lombardy declared to have a ''predialysis'' outpatient department, without, however, specifying its meaning. Research carried out in 2008 among nephrology centers in Piemonte showed how ambiguous this term was. According to the 2007 EDTA-ERA Registry, about 68% of European nephrology centers stated that they had an outpatient department for stage 4-5 CKD patients, but no information was available about the role of patients in the choice of dialysis.

Enterococcus gallinarum endocarditis in a diabetic patient.

Recent studies pointed out the increasing rate of infective endocarditis (IE) in diabetic patients. As diabetes mellitus (DM) prevalence is expected to increase in the coming years, infective endocarditis could be more frequently reported in these patients. We here describe a rare case of Enterococcus gallinarum endocarditis developing on normal native heart valve in an elderly diabetic woman.
