Quantifying the impact of a novel virus on the economic value of pathogen reduction technology for platelets.

Background: Pathogen reduction technology (PRT) is an intervention designed to proactively reduce the amount of known and unknown pathogens in donated blood. As current screening for known pathogens is highly effective, some previous evaluations have found that the value of PRT largely hinges on a previously unknown pathogen, most likely a novel virus, emerging and entering the blood supply. In such situations, the risk of emergence can and should be modeled and presented transparently in the cost-effectiveness results for deliberation by decision-makers.

The evolution of the liver transplant candidate.

The first successful human liver transplant (LT) was done over 60 years ago; since the early pioneering days, this procedure has become a routine treatment with excellent outcomes for the great majority of recipients. Over the last six decades, indications have evolved. Use of LT for hepatic malignancy is becoming less common as factors that define a successful outcome are being increasingly defined, and alternative therapeutic options become available.

Primary biliary cholangitis drug evaluation and regulatory approval: Where do we go from here?

Primary biliary cholangitis (PBC) is a chronic cholestatic liver disease. The management landscape was transformed 20 years ago with the advent of ursodeoxycholic acid. Up to 40% of patients do not, however, respond adequately to ursodeoxycholic acid and therefore still remain at risk of disease progression to cirrhosis.

Organ Transplants From Deceased Donors With Primary Brain Tumors and Risk of Cancer Transmission.

Importance: Cancer transmission is a known risk for recipients of organ transplants. Many people wait a long time for a suitable transplant; some never receive one. Although patients with brain tumors may donate their organs, opinions vary on the risks involved.

Challenges for the maintaining the microbiological safety of the UK blood supply.

The supply of blood, blood products and components in the UK, as elsewhere, is safe, although there is no cause for complacency. Use of blood, blood products and components is not without risk of morbidity and mortality. Transfusion-transmitted infections (TTIs) continue to occur and may severely affect the health and welfare of recipients.

Long-term Care of the Adult Liver Transplant Recipient.

While outcomes after liver transplantation have increased over the last two decades, this is primarily as a consequence of a reduction in early deaths and survival of those who survive the first 6 months has not significantly changed. Causes of premature death and graft loss include cardiovascular disease, renal impairment, malignancy and some infections. As the number of transplant recipients increase, care is being given by primary and secondary care clinicians.

Transplantation of Organs From DCD and DBD Donors Who Died After Ligature Asphyxiation.

Background: The United Kingdom transplant registry data demonstrated similar transplant outcomes for recipients of kidneys from donors who died following ligature asphyxiation and those who received organs from donors dying from other causes. The impact that this donor cause of death has on the outcomes of other solid organ transplant recipients remains uncertain.

Methods: The United Kingdom transplant registry analysis was undertaken to determine transplant outcomes in recipients of lungs, hearts, livers' and pancreases from donors who died following ligature asphyxiation.

Outcomes of incoming and outgoing second opinions from a UK liver transplant centre.

Objective: Second transplant centre opinions (STCOs) for patients declined for liver transplantation are infrequent. We aimed to identify STCOs outcomes from a tertiary transplant centre.

Design: Referrals between 2012 and 2020 to Birmingham Unit were reviewed.

Prevalence of abnormal liver tests and liver fibrosis among rural adults in low and middle-income country: A cross-sectional study.

Background: Liver disease is the only major chronic disease and mortality is increasing. Earlier detection of liver fibrosis can reduce progression to cirrhosis and hepatocellular carcinoma. Many studies have reported an increased prevalence in liver fibrosis among adults in urban regions but there are few data in physically active rural populations without attributable metabolic risk factors.

Consent in organ transplantation: putting legal obligations and guidelines into practice.

Consent in medical practice is a process riddled with layers of complexities. To some extent, this is inevitable given that different medical conditions raise different sets of issues for doctors and patients. Informed consent and risk assessment are highly significant public health issues that have become even more prominent during the course of the Covid-19 pandemic.

Immunosuppression in gastroenterology and hepatology.

In recent years, the clinician has a more diverse approach to immunosuppression. Now, for many conditions, such as solid organ transplantation or treatment of some autoimmune diseases, the consequences of immunosuppression becomes a greater risk than organ failure from immune-mediated disease. Some of the consequences of immunosuppression can be prevented by prophylaxis, immunisation, surveillance and pharmacological intervention.

Organ transplants of the future: planning for innovations including xenotransplantation.

The future clinical application of animal-to-human transplantation (xenotransplantation) is of importance to society as a whole. Favourable preclinical data relevant to cell, tissue and solid organ xenotransplants have been obtained from many animal models utilizing genetic engineering and protocols of pathogen-free husbandry. Findings have reached a tipping point, and xenotransplantation of solid organs is approaching clinical evaluation, the process of which now requires close deliberation.

The Need for Alternatives to Liver Biopsies: Non-Invasive Analytics and Diagnostics.

Histology remains essential for the diagnosis and management of many disorders affecting the liver. However, the biopsy procedure itself is associated with a low risk of harm to the patient and cost to the health services; samples may not be adequate and are subject to sampling variation. Furthermore, interpretation often depends on the skill of the pathologist.

Basiliximab With Delayed Tacrolimus Improves Short-Term Renal Outcomes Post-Liver Transplantation-a Real-World Experience.

Background: Acute kidney injury (AKI) is common after liver transplantation (LT). Induction with interleukin-2 receptor antagonists is often used as a "renal-sparing" strategy. The aim of this study was to assess this approach in a real-world setting in an LT center.

Consent for blood transfusion: summary of recommendations from the Advisory Committee for the Safety of Blood, Tissues and Organs (SaBTO).

The Advisory Committee on the Safety of Blood, Tissues and Organs (SaBTO) decided that its 2011 recommendations on consent for blood transfusion needed to be reviewed and revised due to evidence of poor compliance and recent legal guidance on consent. The recommendations are to ensure that patients are informed about and understand the purpose, benefits and potential risks of transfusion, and have an opportunity to discuss their treatment options. They should be incorporated into local practices for all patients.

Trials & Tribulations of Liver Transplantation- are trials now prohibitive without surrogate endpoints?

During the past 5 decades, liver transplantation has moved from its pioneering days where success was measured in days to a point where it is viewed as a routine part of medical care. Despite this progress, there are still significant unmet needs and outstanding questions that need addressing in clinical trials to improve outcomes for patients. The traditional endpoint for trials in liver transplantation has been 1-year patient survival, but with rates now approaching 95%, this endpoint now poses a number of significant financial and logistical barriers to conducting trials because of the large numbers of participants required to demonstrate only an incremental improvement.

Follow-up of liver transplant recipients.

The number of surviving liver allograft recipients is increasing almost exponentially. The quality and length of life is increasing but most recipients have reduced survival and quality of life compared with healthy matched individuals. Causes of premature death include cardio and cerebrovascular disease, renal failure, graft failure, de novo malignancy and recurrent disease.

Organ utilization - the next hurdle in transplantation?

Nonutilization of organs from consented deceased donors remains a significant factor in limiting patient access to transplantation. Critical to reducing waste is a clear understanding of why organs are not used: accurate metrics are essential to identify the extent and causes of waste but use of these measures as targets or comparators between units/jurisdictions must be done with caution as focus on any one measure may result in unintended adverse consequences. Comparison between centres or countries may be misleading because of variation in definitions, patient or graft characteristics.

Adult liver transplantation: UK clinical guideline - part 2: surgery and post-operation.

Survival rates for patients following liver transplantation exceed 90% at 12 months and approach 70% at 10 years. Part 1 of this guideline has dealt with all aspects of liver transplantation up to the point of placement on the waiting list. Part 2 explains the organ allocation process, organ donation and organ type and how this influences the choice of recipient.

Adult liver transplantation: A UK clinical guideline - part 1: pre-operation.

Liver transplantation is a highly successful treatment for all types of liver failure, some non-liver failure indications and liver cancer. Most referrals come from secondary care. This first part of a two-part guideline outlines who to refer, and how that referral should be made, including patient details and additional issues such as those relevant to alcohol and drug misuse.
