    Anal Cell Pathol (Amst) 2017 17;2017:9404057. Epub 2017 Jan 17.
    Cellular Biomedicine Group, 333 Guiping Road, Shanghai 200233, China; Cellular Biomedicine Group, 19925 Stevens Creek Blvd, Suite 100, Cupertino, CA 95014, USA.
    Because the human heart has limited potential for regeneration, the loss of cardiomyocytes during cardiac myopathy and ischaemic injury can result in heart failure and death. Stem cell therapy has emerged as a promising strategy for the treatment of dead myocardium, directly or indirectly, and seems to offer functional benefits to patients. The ideal candidate donor cell for myocardial reconstitution is a stem-like cell that can be easily obtained, has a robust proliferation capacity and a low risk of tumour formation and immune rejection, differentiates into functionally normal cardiomyocytes, and is suitable for minimally invasive clinical transplantation.

    Human Induced Pluripotent Cell-Derived Sensory Neurons for Fate Commitment of Bone Marrow-Derived Schwann Cells: Implications for Remyelination Therapy.
    Stem Cells Transl Med 2017 Feb 14;6(2):369-381. Epub 2016 Sep 14.
    School of Biomedical Sciences, University of Hong Kong, Hong Kong, People's Republic of China.
    Strategies that exploit induced pluripotent stem cells (iPSCs) to derive neurons have relied on cocktails of cytokines and growth factors to bias cell-signaling events in the course of fate choice. These are often costly and inefficient, involving multiple steps. In this study, we took an alternative approach and selected 5 small-molecule inhibitors of key signaling pathways in an 8-day program to induce differentiation of human iPSCs into sensory neurons, reaching ≥80% yield in terms of marker proteins.

    Due to their capacity to self-renew, proliferate and generate multi-lineage cells, adult-derived stem cells offer great potential for use in regenerative therapies to stop and/or reverse degenerative diseases such as diabetes, heart failure, Alzheimer's disease and others. However, these subsets of cells can be isolated from different niches, each with differing potential for therapeutic applications. The stromal vascular fraction (SVF), a stem cell enriched and adipose-derived cell population, has garnered interest as a therapeutic in regenerative medicine due to its ability to secrete paracrine factors that accelerate endogenous repair, ease of accessibility and lack of identified major adverse effects.

    Cognitive function after heart transplantation: comparing everolimus-based and calcineurin inhibitor-based regimens.
    Clin Transplant 2017 Feb 10. Epub 2017 Feb 10.
    Department of Psychology, University of Oslo, Oslo, Norway.
    Background: Studies have shown conflicting results concerning the occurrence of cognitive impairment after successful heart transplantation (HTx). Another unresolved issue is the possible differential impact of immunosuppressants on cognitive function. In this study, we describe cognitive function in a cohort of HTx recipients and subsequently compare cognitive function between subjects on either everolimus- or calcineurin inhibitor (CNI)-based immunosuppression.

    Objective: To evaluate if development of fragmented QRS (fQRS) complexes, a marker of inhomogeneous ventricular activation due to myocardial fibrosis, is associated with adverse outcome in adults after Mustard/Senning repair for d-transposition of the great arteries (d-TGA).

    Methods: Adults with atrial switch repair for d-TGA were selected from the database of a tertiary care hospital. Exclusion criteria were systemic right ventricular (RV) assist device or heart transplantation (HTx) before the age of 16, or fQRS already present at first visit to the Adult Congenital Heart Disease clinic.

    The process of pediatric solid organ transplantation (SOT) places new and increased stressors on patients and family members. Measures of family functioning may predict psychological and health outcomes for pediatric patients and their families, and provide opportunity for targeted intervention. This systematic review investigated parent and family functioning and factors associated with poorer functioning in the pediatric SOT population. Read More

    Measures of and changes in heart rate variability in pediatric heart transplant recipients.

    Cardiology Section, Department of Pediatrics, Arkansas Children's Hospital, University of Arkansas for Medical Sciences, Cardiology, Little Rock, AR, USA.
    Heart rate variability is primarily regulated by the autonomic nervous system. Heart transplant recipients undergo surgical denervation of the graft, which results in interruption of autonomic innervation with resultant diminished heart rate variability although some degree of autonomic control may return. This study aimed to characterize heart rate variability in this population. Read More

    De novo DQ donor-specific antibodies are associated with worse outcomes compared to non-DQ dnDSA following heart transplantation.
    Clin Transplant 2017 Feb 9. Epub 2017 Feb 9.
    Emory University Center for Heart Failure Therapy and Transplantation.
    Background: Antibody mediated rejection (AMR) resulting from de novo donor-specific antibodies (dnDSA) leads to adverse outcomes following heart transplantation (HTx). It remains unclear what role dnDSA to specific HLA antigens play in adverse outcomes. This study compares outcomes in patients developing dnDSA to DQ antigens with those developing non-DQ dnDSA and those free from dnDSA. Read More
