This issue of the BDD includes firstly the evaluation of a simplified calculation of month-on-month annualized PD associated peritonitis rate (M Marshall et al): the formula is evaluated in the ANZDATA, UZ-DP and RDPLF registries. The aim is to offer teams who do not have sufficient logistical resources a simple way to assess their monthly peritonitis rate.The second article is an annual report fromr the RDPLF on the status of PD in France since the SARS-Cov2 epidemic.
The second part of this issue is a special section devoted to the "DIADOM" day held in Paris in February 2022. Each year the University of Pitié/Salpêtriere -Tenon .
