Response to three doses of the Pfizer/BioNTech BNT162b2 COVID-19 vaccine: a retrospective study of a cohort of haemodialysis patients in France.

Background: The mortality rate associated with coronavirus disease 2019 (COVID-19) is high among haemodialyzed patients. We sought to describe the serological status of haemodialysis patients having received up to three doses of BNT162b2 mRNA vaccine, and to identify factors associated with a poor humoral response.

Methods: We performed a retrospective, observational study of patients attending a dialysis centre in Antibes, France.

Vitamin E-Coated and Heparin-Coated Dialyzer Membranes for Heparin-Free Hemodialysis: A Multicenter, Randomized, Crossover Trial.

Background: Hemodialysis requires effective anticoagulation to avoid blood circuit clotting. In patients at high risk for bleeding, several alternative methods have been developed.

Study Design: Multicenter, prospective, randomized, crossover study evaluating the noninferiority of vitamin E-coated compared with heparin-coated dialyzers in a 4-hour heparin-free hemodialysis strategy.

Phenomenology and psychopathology of excessive indoor tanning.

Excessive indoor tanning, defined by the presence of an impulse towards and repetition of tanning that leads to personal distress, has only recently been recognized as a psychiatric disorder. This finding is based on the observations of many dermatologists who report the presence of addictive relationships with tanning salons among their patients despite being given diagnoses of malignant melanoma. This article synthesizes the existing literature on excessive indoor tanning and addiction to investigate possible associations.
