Addressing the high failure rate of lung transplants

Organ transplant patients routinely receive drugs that stop their immune systems from attacking newly implanted hearts, livers, kidneys or lungs, which the body sees as foreign.But new research at Washington University School of Medicine in St. Louis suggests that broadly dampening the immune response, long considered crucial to transplant success, may encourage lung transplant rejection.

Studies have shown that highly selected patients undergoing combined heart-kidney (HK) and heart-liver transplants (HLv) have short- and long-term outcomes comparable to those observed in primary heart transplantation (HT). Adults patients with stage D heart failure that underwent combined HK, HLv and heart-lung (HL) were identified in the United Network for Organ Sharing (UNOS) registry between 1991 and 2016, with follow-up through March 2018. We conducted inverse probability of treatment weighting (IPTW) survival analysis of long-term survival stratified by type of combined organ transplant, accounting for donor, recipie...

While most people are familiar with the hallmark symptoms of COVID-19 by now—cough, fever, muscle aches, headaches and difficulty breathing—a new crop of medical conditions are emerging from the more than 4 million confirmed cases of the disease around the world. These include skin rashes, diarrhea, kidney abnormalities and potentially life-threatening blood clots. It’s not unusual for viruses to directly infect and affect different tissues and organs in the body, but it is a bit unusual for a primarily respiratory virus like SARS-CoV-2, which is responsible for COVID-19, to have such a wide-ranging reach...

This study provides direct evidence for the contribution of gut microbiota to the cognitive decline during normal aging and suggests that restoring microbiota homeostasis in the elderly may improve cognitive function. On Nutraceutical Senolytics https://www.fightaging.org/archives/2020/05/on-nutraceutical-senolytics/ Nutraceuticals are compounds derived from foods, usually plants. In principle one can find useful therapies in the natural world, taking the approach of identifying interesting molecules and refining them to a greater potency than naturally occurs in order to produce a usefully large therape...

Organ transplantation is undergoing profound changes. Contraindications for donation have been revised in order to better meet the organ demand. The use of lower-quality organs and organs with greater preoperative damage, including those from donation after cardiac death (DCD), has become an established routine but increases the risk of graft malfunction. This risk is further aggravated by ischemia and reperfusion injury (IRI) in the process of transplantation. These circumstances demand a preservation technology that ameliorates IRI and allows for assessment of viability and function prior to transplantation. Oxygenated h...

(University of Pennsylvania School of Medicine) France and the United States have experienced a tremendous reduction in the number of organ donations and solid organ (kidney, liver, heart, and lung) transplant procedures since the onset of the COVID-19 pandemic. By early April, transplant centers in both countries were conducting far fewer deceased donor transplants compared to just one month earlier, with the number of procedures dropping by 91% in France and 50% in the United States.

This study is par for the course, looking at Japanese Olympic participants. Interestingly, it hints at the upper end of the dose-response curve for physical activity, in that a longer career as a professional athlete may be detrimental in comparison to lesser degrees of exercise and training. From this large, retrospective cohort study targeting 3546 Japanese Olympic athletes, we observed significant lower mortality among Olympians compared with the Japanese general population. The overall standardised mortality ratio (SMR) was 0.29. The results were consistent with previous studies conducted in other non-Asian co...

This study delves into the mechanisms by which a short period of fasting can accelerate wound healing. Fasting triggers many of the same cellular stress responses, such as upregulated autophagy, as occur during the practice of calorie restriction. It isn't exactly the same, however, so it is always worth asking whether any specific biochemistry observed in either case does in fact occur in both situations. In particular, the period of refeeding following fasting appears to have beneficial effects that are distinct from those that occur while food is restricted. Multiple forms of therapeutic fasting have been repor...

The development of post-transplant diabetes mellitus (PTDM) is associated with an increased risk of acute rejection after kidney and liver transplantation, however, the outcomes after orthotopic heart transplant (OHT) have yet to be systematically studied. We sought to investigate whether there is any relationship between the development of PTDM and acute rejection after cardiac transplant.
