Research on 3D scaffolds sets new bar in lung regeneration

In end-stage lung disease, transplantation is sometimes the only viable therapeutic option, but organ availability is limited and rejection presents an additional challenge. Innovative research efforts in the field of tissue regeneration, including pioneering discoveries by University of Vermont Professor of Medicine Daniel Weiss, M.D., Ph.D., and colleagues, hold promise for this population, which includes an estimated 12.7 million people with chronic obstructive pulmonary disorder (COPD), the third leading cause of death in the U.S.

ConclusionLV echocardiographic parameters (LVESD or LVEDD) are useful in predicting survival in patients with end ‐stage lung diseases, mainly in IPF patients awaiting LT. Other parameters (RV/LV ‐ 4CH and RVOT‐PLAX dilatation) may also influence survival.This article is protected by copyright. All rights reserved.

Authors: Poggi C, Mantovani S, Pecoraro Y, Carillo C, Bassi M, D'Andrilli A, Anile M, Rendina EA, Venuta F, Diso D Abstract Chronic obstructive pulmonary disease (COPD) is the major causes of disability and mortality. The efficacy of maximal medical treatment, although effective at the early stages of the disease, becomes limited when extensive alveolar destruction is the main cause of respiratory failure. At this stage of the disease more aggressive options, when feasible, should be considered. Lung transplantation and lung volume reduction surgery (LVRS) are currently available for a selected group of patients. E...

By ANISH KOKA MD  The message comes in over the office slack line at 1:05 pm. There are four patients in rooms, one new, 3 patients in the waiting room. Really, not an ideal time to deal with this particular message. “Kathy the home care nurse for Mrs. C called and said her weight yesterday was 185, today it is 194, she has +4 pitting edema, heart rate 120, BP 140/70 standing, 120/64 sitting” I know Mrs. C well. She has severe COPD from smoking for 45 of the last 55 years. Every breath looks like an effort because it is. The worst part of it all is that Mrs. C just returned home from the hospital just days...

This study suggests that advantages and disadvantages vary by environment and diet, however, which might explain why evolution has selected for multiple haplogroups rather than one dominant haplogroup. This is all interesting, but none of it stops the research community from engineering a globally better-than-natural human mitochondrial genome, and then copying it into the cell nucleus as a backup to prevent the well-known contribution of mitochondrial DNA damage to aging. Further, nothing stops us from keeping the haplogroups we have and rendering the effects of variants small and irrelevant through the development...

Abstract COPD-associated chronic inflammation has been shown to lead to an autoimmune phenotype characterized in part by the presence of lung reactive autoreactive antibodies. We hypothesized that ischemia reperfusion injury (IRI) liberates epitopes that would facilitate pre-existing autoantibody binding, thereby exacerbating lung injury post-transplantation. We induced emphysema in C57BL/6 mice through 6 months of cigarette smoke exposure (CS). CS exposure significantly elevated serum autoantibodies compared to non-smoke age-matched (NS) mice. To determine the impact of a full pre-existing autoantibody repertoire...

ABSTRACT The study of the human microbiome-and, more recently, that of the respiratory system-by means of sophisticated molecular biology techniques, has revealed the immense diversity of microbial colonization in humans, in human health, and in various diseases. Apparently, contrary to what has been believed, there can be nonpathogenic colonization of the lungs by microorganisms such as bacteria, fungi, and viruses. Although this physiological lung microbiome presents low colony density, it presents high diversity. However, some pathological conditions lead to a loss of that diversity, with increasing concentrations of so...

Conclusion: As for cardiac or hepatic transplantations, despite a strong immunosuppressive regimen, a high frequency of transient PF4/H Ab is observed in patients undergoing BLT. Their appareance is not related to thrombocytopenia and/or thrombotic events. However, they could be an early marker of a cellular reaction againts the graft.DisclosuresNo relevant conflicts of interest to declare.

Authors: Slama A, Taube C, Kamler M, Aigner C Abstract Lung transplantation (LuTX) and lung volume reduction (LVR), either surgical (LVRS: lung volume reduction surgery) or endoscopic (ELVR: endoscopic lung volume reduction), are established therapies in the treatment of end-stage chronic obstructive pulmonary disease (COPD) patients. Careful patient selection is crucial for each intervention. If these techniques are sequentially applied there is a paucity of available data and individual center experiences vary depending on details in selection criteria and operative technique. This review aims to summarize the pu...
