Unlabelled: The free-living amoebae (FLA) are ubiquitous and opportunistic protozoa. They can induce human and animal diseases. The aim of our study was to detect the FLA and Acanthamoeba genus in the hydraulic system of an hemodialysis unit. It was a prospective study of 46 water samples. The first collect (23) was before cleaning and after the haemodialysis sessions and the second (23) after cleaning and before the hemodialysis sessions.
Results: the morphological study enabled us to detect morphotypic diversity. The predominant morphotypes were the acanthopodial forms (29%). At the entrance of hemodialysis unit there were acanthopodial (44%) and monotactic (25%) forms; at the outlet, acanthopodial and fan-shaped forms (25% each). In addition, Acanthamoeba genus was present in 39% (1st collect) and 18% (2nd collect). The amplification of the FLA 18S rDNA gene was negative in only one sample localized in the last stage of water treatment unit (WTU). The amplification of the 18S rDNA (ASA.A1) Acanthamoeba gene was positive in 15 samples.
Conclusions: we noted that, in the hemodialysis unit, the purification techniques used in the WTU were effective, but there is a problem of water stagnation in the drain, which constitutes an appropriate condition for the biofilms formation. It is then necessary to use a filter with a low porosity (0.2 microm) at the entrance of the hemodialysis unit and if possible to change the drain.

Objective: This retrospective, single centre, comparative effectiveness study aimed to compare the long term outcomes of percutaneous arteriovenous fistulae (pAVF) and surgically created arteriovenous fistulae (sAVF) created in the proximal forearm for haemodialysis access.
Methods: Data were reviewed from a prospectively maintained database on patients who underwent pAVF or sAVF creation from September 2017 to September 2023. A total of 217 pAVFs (61 WavelinQ and 156 Ellipsys) and 158 sAVFs were analysed.

: Home rehabilitation improves patient satisfaction and reduces the need for specialist consultations. Hemodialysis is a costly post-ICU service that requires frequent monitoring. Previous studies have demonstrated the feasibility and accuracy of patients self-scanning their lungs with an ultrasound device within the hospital.

: Knee pain in hemodialysis (HD) patients might affect health-related quality of life (HRQoL) and may be related to anxiety and depressive symptoms. The aim of this study was to assess the prevalence of knee pain in chronic HD patients and to determine its relationship with anxiety, depression, and HRQoL, : This multicenter cross-sectional study was carried out on chronic HD patients. Sociodemographic, clinical, and therapeutic data were collected.

: The bite of the Loxosceles spider is a public health problem around the world, mainly in Latin America. The viscerocutaneous presentation is related to the inoculation of toxins (phospholipase-D) that generates a systemic inflammatory reaction with a subsequent increase in cytokines and chemokines. Hemoadsorption is proposed as a therapy that allows for the removal of the toxin and modulation of the inflammatory response in this disease.

: Vancomycin is a reserve antibiotic that is frequently prescribed for central venous catheter (CVC)-associated infections in hemodialysis patients. Hemodialysis patients are very fragile patients and the presence of CVCs increases the risk of sepsis. We conducted a prospective study, evaluating the needs of changes in vancomycin dosing for treatment based on the use of the new 2020 vancomycin dosing guidelines, to increase drug safety (preventing subtherapeutic or supratherapeutic doses and offering therapeutic concentrations of the drug) in a particular group of patients with sepsis caused by catheter infections and being on intermittent hemodialysis.
