Haemodialysis facilities have a large environmental impact due to high energy, water and consumable usage by haemodialysis equipment. As climate change and natural resource scarcity escalate, all the while the number of people requiring dialysis increases, there is an urgent need for dialysis facilities that meet care needs while minimising environmental impact. To address this, the Australian and New Zealand Society of Nephrology engaged an environmental sustainability consulting practise to develop a best practise guide for the environmentally sustainable design and operation of haemodialysis facilities.

Toll-like receptors (TLR) provide a potential link between infection and anti-myeloperoxidase (MPO) autoimmunity. TLR9 ligation has been shown to promote anti-MPO autoimmunity and glomerular vasculitis in murine MPO-AAV.

A 64-year-old gentleman initially presented with nephrotic syndrome and membranous nephropathy with positive staining for C1q, which was suspicious for lupus membranous nephritis. Investigation led to the simultaneous diagnosis of colorectal cancer (CRC). The CRC was surgically excised and the patient's nephrotic syndrome resolved.

This study examined intrarenal TLR2, TLR4, and TLR9 expression and renal injury in AAV, testing the hypothesis that increased TLR expression correlates with renal injury. Patients with AAV exhibited both glomerular and tubulointerstitial expression of TLR2, TLR4, and TLR9, with TLR4 being the most prominent in both compartments.

C5aR1 primes neutrophils for activation by anti-neutrophil cytoplasmic antibody (ANCA) and is therefore required in models of glomerulonephritis induced by anti-myeloperoxidase antibody. Although humoral and cellular autoimmunity play essential roles in ANCA-associated vasculitis, a role for C5aR1 in these responses has not been described.

View Article and Find Full Text PDFMyeloperoxidase (MPO) is an important neutrophil lysosomal enzyme, a major autoantigen, and a potential mediator of tissue injury in MPO-ANCA-associated vasculitis (MPO-AAV) and glomerulonephritis. Here we examined MPO deposition in kidney biopsies from 47 patients with MPO-AAV. Leukocyte accumulation and fibrin deposition consistent with cell-mediated immunity was a major feature.

The aim of this study was to determine whether hyperbaric oxygen therapy (HBOT) is effective in healing calciphylaxis lesions and to determine if there are any patient factors that can predict wound healing and patient survival.
Methods: We identified by retrospective review all cases of CUA referred to our institution for treatment with HBOT.
Background: A predictive histologic classification recently was proposed to determine the prognostic value of kidney biopsy in patients with antineutrophil cytoplasmic antibody-associated renal vasculitis (AAV).
Study Design: A dual-purpose retrospective observational cohort study to assess the reproducibility of the new classification and clinical variables that predict outcomes.
Setting & Participants: 169 consecutive patients with AAV were identified; 145 were included in the reproducibility study, and 120, in the outcomes study.
The risk of developing an intraoperatively acquired pressure ulcer (IAPU), which is recognized as a significant complication of deep tissue injury occurrence, is associated with duration of surgery and patient positioning. There is a strong association between hypothermia, tissue viability, and surgical site infections; however, the relationship between hypothermia and pressure ulcers has not been fully explored. We examined the incidence of pressure ulcers in surgical patients and determined that there is a relationship between maintaining perioperative normothermia and a reduction in IAPU development.

Highly sensitive assays for detecting recipient preformed anti-HLA antibodies have been developed and identify high immunological risk donors. A 62yo male with end stage renal failure secondary to glomerulonephritis received a T-cell crossmatch negative, deceased donor, renal transplant mismatched at 3 of 6 HLA loci.

Direct half-life measurement showed that mutation of the (CAUU)4 stabilizes Fed-1 mRNA in the dark. (CAUU)1, a feature more common in plant 5' UTRs than (CAUU)4, confers slight light-responsive mRNA accumulation.

A sensitivity of 10 bacteria/ml was achieved in the laboratory. Treatment of milk samples with a detergent (Lubrol PX) and a proteolytic enzyme (trypsin) allowed filtration of 50 ml of milk through a 0.
