MedicalResearch.com Interview with: Lead Author: Rupak Desai, MBBS Atlanta Veterans Affairs Medical Center Independent Researcher, Atlanta, GA, Presenter: Vamsikalyan Borra, MD Resident Physician, Internal Medicine University of Texas Rio Grande Valley, Weslaco, TX MedicalResearch.com: What is the background for this study? Response: The relationship between sleep apnea (OSA) and chronic kidney disease (CKD) is quite complex. OSA can cause hypoxia, activation of the sympathetic nervous system, and hypertension, all of which can have negative effects on kidney function. On the other hand, in patients with end-stage renal disease (ESRD), intensifying renal replacement therapy has shown some improvement in sleep apnea severity, suggesting a bi-directional relationship between the two conditions. While there are still uncertainties, recent studies have focused on understanding the interplay between OSA and CKD. The role of CPAP therapy, a common treatment for OSA, in relation to CKD is not yet clear. Observational studies present findings regarding the impact of CPAPs on kidney function. However, researchers are actively investigating its cardiovascular benefits and its influence on the progression of CKD. The objective of this study is to analyze the trends in composite cardiovascular events in hospital encounters among geriatric patients with CKD, comparing those with and without obstructive sleep apnea. Additionally, we are also investigating sex and racial disparities in trends of major adverse cardiovascular and cerebrovascular events (MACCE) among geriatric patients with obstructive sleep apnea (OSA). Furthermore, we are assessing the impact of continuous positive airway pressure (CPAP) treatment and dependence on MACCE outcomes in OSA patients (more…)

MedicalResearch.com Interview with: Prof. Dr. Wolfram-Hubertus Zimmermann Director, Institute of Pharmacology and Toxicology University Medical Center Göttingen Georg-August University Göttingen, Germany   MedicalResearch.com: What is the background for this study? Response: Involvement in research and development in the field of tissue engineered heart repair since 25+ years. Bench-to-bed translation of our research. MedicalResearch.com: How are the stem cell obtained? Response: We make use of induced pluripotent stem cells as starting material to obtain heart muscle cells for the engineering of Engineered Human Myocardium (EHM) and its use as Biological Ventricular Assist Tissue (BioVAT).
