Effects of bone marrow ‑derived mesenchymal stem cell transplantation on chronic obstructive pulmonary disease/obstructive sleep apnea overlap syndrome in rats.

Effects of bone marrow‑derived mesenchymal stem cell transplantation on chronic obstructive pulmonary disease/obstructive sleep apnea overlap syndrome in rats. Mol Med Rep. 2019 Sep 30;: Authors: Chen M, Huang Z, Bi H, Pan X, He J, He L, He X, Du J, Zhou K, Wang L, Wang Q, Guo X, Jin Z Abstract Bone marrow‑derived mesenchymal stem cells (BMSCs) possess potential therapeutic properties for treating patients with chronic obstructive pulmonary disease (COPD), which is characterized by emphysema and obstructive sleep apnea (OSA). However, their effects on overlap syndrome (OS) remain unclear. We investigated the potential therapeutic effects and possible mechanisms of BMSC transplantation in OS rats. To generate the OS model in rats, the animals underwent daily exposure to cigarette smoke and intermittent hypoxia. BMSCs were intravenously injected into rats. At 4 weeks post‑transplantation, the severity of emphysema was assessed by lung hematoxylin and eosin (H&E) staining. The levels of oxidative stress and the malondialdehyde (MDA) and superoxide dismutase (SOD) contents in serum and lung were detected. The apoptosis of alveolar septal cells was also detected by TUNEL assay. Finally, we determined the expression of CD31 and VWF in lung tissues by an immunohistochemical (IHC) assay. It was found that BMSCs were able to migrate to the injured lung and aorta tissues. In lung tissues, transplanted BMSCs, some of which had differentiated into endothel...

CONCLUSIONS: This pilot study demonstrated an improved medication reconciliation process with pharmacist involvement, expanding the body of evidence that pharmacists can enhance TOC management in an inpatient setting. These results highlight the utility of a pharmacist in the implementation and refinement of TOC services and provides impetus for a team-based approach when patients experience a TOC.

This is especially important for COPD patients, but also for a variety of other disorders of the respiratory system. At the workshop "Luftschlösser", held once more at Wiesbaden, Germany in February 2019 the many and important interactions of the lungs and the heart as well as the therapeutic implications were discussed. Based on pathophysiology, the psycho-social consequences of dyspnea, t...

Conclusion Analysis of the pleiotropic effects of IL-33 on multiple immunological cells (macrophages, mastocytes), as well as neurological cells of medulla oblongata, dorsal root ganglion, antigen-induced arthritis system, carrageen, and formalin, shows that this alarmin plays curtail, yet not fully known role in mediating inflammation, especially in chronic inflammatory pulmonary diseases such as asthma, COPD, and OSA. Taken into consideration the engagement in this process, in particular of mastocytes and their secretion of CXCL2, 4, 8, and other cytokines, there is no doubt regarding the etiopathogenic role of IL-33 in...

Abstract PURPOSE: Obstructive sleep apnea and chronic obstructive pulmonary disease are independent risk factors of cardiovascular disease (CVD), and their coexistence is known as overlap syndrome (OS). Endothelial dysfunction is the initial stage of CVD; however, underlying mechanisms linking OS and CVD are not well understood. The aim of this study was to explore whether OS can lead to more severe inflammation and endothelial apoptosis by promoting endothelial dysfunction, and to assess the intervention effects of antioxidant tempol. MATERIALS AND METHODS: Male Wistar rats (n=66) were exposed to normal oxyg...

Authors: Yu H, Shao H, Wu Q, Sun X, Li L, Li K, Li X, Li Y, Zhang Q, Wu J, Chen H Abstract Patients with respiratory overlap syndrome (OS), defined as concomitant chronic obstructive pulmonary disease and obstructive sleep apnea syndrome, may exhibit an increased blood concentration of ingested drugs. This poor elimination of drugs is primarily attributed to downregulated gene expression of the drug‑metabolizing cytochrome P450 enzymes (CYPs) in the liver. However, the underlying mechanisms of the decreased expression of CYPs in OS are poorly understood. In order to address this, a rat model of intermittent hypox...

Abstract Chronic obstructive pulmonary disease (COPD) and obstructive sleep apnea syndrome (OSA) are both highly prevalent, which implies that both disorders occurring together (overlap syndrome) is likely to be common based on chance association alone. However, different clinical COPD phenotypes influence the likelihood of co-existing OSA in that the increased lung volumes and low body mass index (BMI) associated with the predominant emphysema phenotype protects against OSA, whereas the higher likelihood of peripheral edema and increased BMI associated with the predominant chronic bronchitis phenotype promotes OS...
