Hope for transplant patients as study finds key to organ scarring

Patients with damaged organs could be helped by new treatments after scientists have discovered how tissues scar. Researchers say that the finding could pave the way for new drugs and eventually reduce the number of patients on organ transplant waiting lists. Fibrotic diseases occur in many tissues within the body - including the liver, lung or kidneys - and have a range of causes including viruses or toxins. Experts say that the main source of scar tissue is found in specialised cells called Myofibroblasts...

This study provides a possible reason why genes carrying health risks have persisted in human populations. The second found evidence for multiple variants in genes related to ageing that exhibited antagonistic pleiotropic effects. They found higher risk allele frequencies with large effect sizes for late-onset diseases (relative to early-onset diseases) and an excess of variants with antagonistic effects expressed through early and late life diseases. There also exists other recent tangible evidence of antagonistic pleiotropy in specific human genes. The SPATA31 gene has been found under strong positive genomic sele...

Cervical cancer is the most common gynecological cancer worlwide. Squamous intraepithelial lesions (SIL) are known precursors for carcinoma of uterine c èrvix and associated to infection by human papillomavirus (HPV). Several studies have shown an increased risk of malignant anogenital lesions in recipients of kidney and liver transplants compared to the general population, but there is less information in heart transplanted recipient

Right heart failure following left ventricular assist device implantation is one of the major challenges in patients suffering from advanced heart failure. There is still no ideal right-sided support system available. Here we describe the implantation of a stent valve at the inferior cavoatrial junction to protect liver and kidney during right heart failure.

The impact of opioid use in lung transplant (LTx) candidates on post-transplant outcomes is unknown. Previous studies on opioid therapy in kidney and liver transplant candidates have suggested increased risk of graft failure or death. We sought to test the association between pre-transplant opioid use in LTx candidates and overall retransplant-free survival.

The Model of End-Stage Liver Disease (MELD) score incorporates measures of kidney and liver dysfunction. MELD score has been shown to predict mortality in patients with advanced heart failure or cardiogenic shock (CS). Prior small single-center studies have shown that MELD score predicts mortality in patients supported with Venoarterial Extracorporeal Membrane Oxygenation (VA-ECMO). The Purpose of our was to reassess the role of MELD score predicting Mortality After (VA-ECMO).

This is the organoid era of tissue engineering. Researchers are making earnest progress in establishing the recipes that allow cells to be grown into small, functional tissue sections. They lack a network of capillaries, however, so must be no more than a millimeter or so in thickness in order for nutrients to perfuse sufficiently through the tissue to support all of its cells. Every organ, every tissue has a significantly different recipe, but it is usually something that can be derived from an examination of the biochemistry of embryonic growth, with enough time and funding. Given the large number of different tissues ve...

Publication date: Available online 16 February 2019Source: Social Science &MedicineAuthor(s): Athena EngmanAbstractThe concept of biographical disruption has now enjoyed nearly 40 years of use in medical sociology. This paper argues that taking an embodied approach to biographical disruption helps to explain the concept's enduring efficacy. Drawing on the work of Maurice Merleau-Ponty and contemporary theories of embodiment inspired by his phenomenology, this paper advances that biographical disruption involves, in the first instance, a disruption to the ability to enact an embodied orientation towards the world. Biogr...
