Unlabelled: Nasal carriage of Staphylococcus aureus may be responsible for some serious infections among hemodialyzed patients. Its pathogenic potential and commensal nature allows for an easy transmission both in and out of hospital environment.
Purpose: This study was to assess the prevalence of S. aureus nasal carriage, to determine its frequency and nature in hemodialyzed patients of the Rabat Ibn Sina University hospital, in Morocco.
Patient And Method: The study began in March 2008 according to the following protocol: screening of nasal carriage with five samplings, performed once a month three times, then once a month two times again after an interruption period of three months. Screening was performed weekly during the first month in hemodialyzed patients treated with mupirocin (Bactroban(®) 2%), and then monthly, to monitor the kinetics of S. aureus eradication.
Results: The study included 54 hemodialyzed patients with a mean 44.16±14 years of age, sex ratio of 0.54, and mean hemodialysis duration of 118.7±67 months. Permanent and intermittent S. aureus carriage was found in respectively 18.52% and 25.92% of patients. Eighty-one strains of S. aureus were identified, 14.81% of which were methicillin resistant. Eradication was sustained beyond 20 months in patients treated with mupirocin.
Conclusion: This investigation allowed us to identify hemodialyzed patients at risk, so as to implement the rules of individual and collective hygiene, and to extend mupirocin antibiotic prophylaxis in our hemodialysis unit.

Introduction: Pain is one of the most frequently reported symptoms in hemodialyzed (HD) patients, with prevalence rates between 33% and 82%. Risk factors for chronic pain in HD patients are older age, long-lasting dialysis history, several concomitant diseases, malnutrition, and others. However, chronic pain assessment in HD patients is rarely performed by specialists in pain medicine, with relevant consequences in terms of diagnostic and treatment accuracy.

Background: Cardiovascular diseases are one of the major limitations in the evaluation of potential kidney transplantation. The study aimed to assess cardiovascular status, including cardiovascular risk factors in waitlisted hemodialyzed patients.
Material And Methods: From the population of 5,068 hemodialyzed patients (60% men), we included 449 waitlisted and 4,619 not considered for potential kidney transplantation.

Introduction The SARS-CoV-2 virus causes the highly contagious coronavirus disease 2019 (COVID-19), which most commonly manifests as severe acute respiratory syndrome. The virus is part of the Coronaroviridae family, a group of viruses that can cause various diseases, such as the common cold, severe acute respiratory syndrome (SARS), and Middle East respiratory syndrome (MERS). The World Health Organization (WHO) declared the outbreak of COVID-19 as a pandemic on March 11, 2020.

Regional citrate anticoagulation use in intermittent hemodialysis is limited by the increased risk of metabolic complications due to faster solute exchanges than with continuous renal replacement therapies. Several simplifications have been proposed. The objective of this study was to validate a mathematical model of hemodialysis anticoagulated with citrate that was then used to evaluate different prescription scenarios on anticoagulant effectiveness (free calcium concentration in dialysis filter) and calcium balance.

Purpose: An overview of the current pharmacological treatment and psychosocial interventions, such as cognitive-behavioral therapy and breathing exercises, for depression and anxiety among hemodialyzed patients (HD).
Views: Depression and anxiety are common problems among HD patients, influencing their mortality and morbidity; however, they are often under-recognized and under-treated. Even though the topic is attracting more scientific attention there are still only few studies about methods of treatment for those disorders.
