The Research Board of the European Dialysis and Transplantation Nurses Association/European Renal Care Association (EDTNA/ERCA)

The Research Board (RB) of EDTNA/ERCA is a multidisciplinary group, established by the participation of renal care centres all around Europe. The RB also works with the association's Special Interest Groups (SIGs) on developing guidelines for implementing safe renal clinical practice. It is composed of six permanent members, with co-opted experts from specific fields. This article describes how the RB works and the projects implemented since 1996.     

European study on epidemiology and the management of HCV in the haemodialysis population--Part 1: centre policy

Haemodialysis patients are known to be at risk of infection of Hepatitis C Virus (HCV) through nosocomial spread. This paper presents the first part of a study on epidemiology and management of HCV, in a haemodialysis population, conducted by the EDTNA/ERCA Research Board. Data on HCV management and infection control procedures was collected from 136 European centres using an electronic questionnaire. The study identifies a number of possible risk factors for transmission of the virus: failing to disinfect devices between patients, sharing of single-use vials to prepare drugs or infusions for different patients, inadequate sterilisation or cleaning of machines between dialysis sessions, unsatisfactory environmental cleaning and distance less than one metre between chairs.     

Studies on isolated rat adrenal cells. I. Continuous flow and batch incubation.

A procedure for the continuous flow incubation of isolated adrenal cells is described. In this way the advantages of continuous flow incubations of adrenal tissue are combined with those of isolated adrenal cells. Suspensions of isolated adrenal cells were prepared by a modification of the collagenase method. A sigmoid dose-response curve was obtained when these cells were incubated with ACTH in batch incubations. Under these conditions (in the presence of 1 mU ACTH/ml) the corticosterone production rate remained constant during at least 240 min. This production rate was linearly related to the number of cells. Pre-incubation of the cells during 3 h resulted in an increased response to ACTH. In continuous flow incubations without ACTH the corticosterone production was negligible. With 100 mu U ACTH/ml corticosterone production increased sharply after a short lag period. A maximum was reached after 60-75 min followed by a slow decrease. Cells pre-incubated in the continuous flow apparatus had a slightly diminished ACTH response without loss of affinity to ACTH. The continuous flow incubation of isolated adrenal cells offers new possibilities for the dynamic study of steroid biosynthesis in vitro. The method may also be valuable to study processes in a wide variety of other tissues.

Characterisation of ecto- and endoparasites in domestic cats from Tirana,Albania

During 2008 to 2011, faecal samples, ear swabs, and ectoparasites obtained by full body search and total body comb were collected from 252 cats originating from the greater Tirana area. Faecal samples were examined using the McMaster and Baermann techniques, and a subset of 58 samples was tested for Giardia-specific antigen using a coproantigen enzyme-linked immunosorbent assay (ELISA). The ear swabs were examined for the presence of parasitic mites. Overall, almost 93 % of the cats were identified harbouring one or more parasites: 59.1 % (95 % confidence interval (CI), 53.0–65.0) and 86.9 % (95 % CI, 82.7–91.1) of the cats tested positive for ecto- or endoparasites, respectively; 53.2 % of the cats had evidence for concomitant ectoparasite infestation and endoparasite infection. For ectoparasite infestation, prevalence was 52.0 % for total fleas (Ctenocephalides felis, 51.2 %; Ctenocephalides canis, 2.0 %; and Leptopsylla segnis, 0.4 %), 8.3 % each for Felicola subrostratus and Otodectes cynotis and 4.0 % for Rhipicephalus sanguineus sensu lato. The most prevalent endoparasites were Toxocara ascarids (48.0 %), followed by Aelurostrongylus lungworms (39.7 %), Capillaria spp. (31.7 %), hookworms (32.9 %), dipylidiid cestodes (27.8 %), Cystoisospora spp. (23.4 %) and taeniid cestodes (2.0 %). One animal was found shedding Pseudamphistomum truncatum eggs. Giardia-specific antigen was detected in 29.3 % of the 58 cats tested. Mixed infections with up to six endoparasites concurrently (excluding Giardia) and mixed infestations with two or three species of ectoparasites were recorded in 73.1 and 22.8 % of the parasite-positive cats, respectively. Cats ≤9 months of age were more frequently tested (p?Toxocara and Cystoisospora infections than cats >9 months while these cats tested more often (p?Aelurostrongylus-positive compared with the younger cats. The prevalence of infestation with ectoparasites did not differ between the cats of these two age groups. Given the impact that some of the parasites may have upon animal health as well as the zoonotic potential of some of them, measures should be taken to minimise the transmission of these parasites.     

Survival, but not maturation, is affected in neutrophil progenitors from GSD-1b patients

Glycogen storage disease type 1b (GSD 1b) is caused by mutations in the Glucose-6-phosphate transporter and is characterized by impaired glucose homeostasis. In addition, GSD-1b is associated with chronic neutropenia resulting in recurrent infections and inflammatory bowel disease. It is unclear whether the neutropenia is solely due to enhanced apoptosis of mature neutrophils or whether aberrant neutrophil development may also contribute. Here we demonstrate that hematopoietic progenitors from GSD-1b patients are not impaired in their capacity to develop into mature neutrophils. However, optimal survival of neutrophil progenitors from GSD-1b patients requires high glucose levels (> 200 mg dl⁻¹), suggesting that even under normoglycemic conditions these cells are more prone to apoptosis. Furthermore, analysis of cytokine levels in peripheral blood suggests an inflammatory state with an inverse correlation between the level of inflammation and the number of neutrophils. Finally, in some patients, with low numbers of peripheral blood neutrophils, high numbers of neutrophils were observed in the intestine. Together, these results suggest that the neutropenia observed in GSD-1b patients is not caused by impaired maturation, but may be caused by both increased levels of apoptosis and egress of neutrophils from the blood to the inflamed tissues.     

Morbidity related to defunctioning ileostomy closure after ileal pouch-anal anastomosis and low colonic anastomosis

Purpose  

Defunctioning ileostomies are widely performed in order to prevent or treat anastomotic leakage after colorectal surgery. The aim of the present study was to determine morbidity related to stoma closure and to identify predictive factors of a complicated postoperative course.     

Predictors of health-related quality of life in patients treated with auto- and allo-SCT for hematological malignancies

Identifying factors that predict health-related quality of life (QOL) following hematopoietic SCT, is important in estimating patients' abilities to adjust to the consequences of their disease and treatment. As the studies that have been published on this subject are scattered, the present study aimed to systematically review prognostic factors for health-related QOL after auto- and allo-SCT in hematological malignancies. A systematic, computerized search in Medline, EMBASE, PsycINFO and the Cochrane Library was conducted from 2002 to June 2010. The methodological quality of the studies was assessed using an adaptation of Hayden's criteria list. Qualitative data synthesis was performed to determine the strength of the scientific evidence. In all, 35 studies fulfilled the selection criteria. Strong-moderate evidence was found for GVHD, conditioning regimen, being female, younger age, receiving less social support and pre-transplant psychological distress as predictors of various aspects of health-related QOL following hematopoietic SCT. The results of this review may help transplant teams in selecting patients at risk for experiencing a diminished health-related QOL following hematopoietic SCT. Follow-up treatment can be provided in order to promote QOL.
