Neutrophils rapidly undergo spontaneous apoptosis, but this process can be considerably delayed by exposure to a variety of agents such as pro-inflammatory cytokines. The anti-apoptotic protein of the Bcl-2 family, Mcl-1, plays a key role in the regulation of neutrophil apoptosis. The protein has some unusual properties compared with other family members, including an extremely high turnover rate. Many factors, such as cytokines and local oxygen concentrations, can regulate cellular levels of Mcl-1 via transcription and post-transcriptional modification, control the survival time of neutrophils within tissues and thereby influence the inflammatory response.
Our prospective study is the first and currently the largest observational study of a multidisciplinary approach in the management of NDT patients. SCG was an independent prognostic factor in predicting survival. In those patients who chose not to dialyse, SCG provides a potentially useful indication of expected prognosis.
Substance abuse has been increasing steadily in the UK and some other countries. Recent evidence suggests more than 40% of young people have tried illicit drugs at some time. There are numerous medical consequences to recreational drug use, and a physician should always consider substance abuse in any unexplained illness. The renal complications of drug abuse are also becoming more frequent, and may encompass a spectrum of glomerular, interstitial and vascular diseases. Although some substances are directly nephrotoxic, a number of other mechanisms are also involved. These effects are often chronic and irreversible, but occasionally acute with possible recovery. The rapid growth of illicit drug use is clearly a major public health problem. We review the commonly used substances of abuse and their associations with renal disease.
In kidney transplantation, operational tolerance and almost tolerance are infrequent findings associated with excellent long-term death-censored graft survival.
Improvement in end-of-life-care is required for patients dying with chronic kidney disease (CKD). The UK government now recommends that tools such as the Liverpool Care Pathway for the Dying Patient (LCP) be used to enhance the care of those patients dying with CKD. The LCP was originally developed for patients dying with terminal cancer, however has been shown to be transferable to patients dying with heart failure or stroke. On this background, in 2005 a UK National Renal LCP Steering Group was formed. The aim was to determine whether or not the generic LCP was transferable to patients dying with CKD. An Expert Consensus sub-group was established to produce evidence-based prescribing guidelines to allow safe and effective symptom control for patients dying with renal failure. These guidelines were finalised by the Expert Consensus group in August 2007 and endorsed by the Department of Health in March 2008. A literature search on symptom control and end-of-life care in renal failure was performed. A summary of the evidence was presented at a National Steering Group meeting. Opinions were given and provisional guidelines discussed. A first draft was produced and individually reviewed by all members of the Expert Group. Following review, amendments were made and a second draft written. This was presented to the entire National Steering Group and again individual comments were taken into consideration. A third and fourth draft were written and individually reviewed, before the guidelines were finalised by the Expert Consensus group. Patients dying with advanced CKD suffer symptoms similar to patients dying of cancer. The Renal LCP prescribing guidelines aim to control the same symptoms as the generic LCP: pain, dyspnoea, terminal restlessness and agitation, nausea and respiratory tract secretions. The evidence for the production of the guidelines is discussed and how a consensus was reached. A summary of the guidelines is given and the complete guidelines document is available via the Marie Curie Palliative Care Institute, Liverpool website.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
