Establishing a Graft-Versus-Host Disease (GVHD)-Focused Multidisciplinary Telehealth Clinic.

Graft-versus-host disease (GVHD) is a complication following allogeneic hematopoietic cell transplant that frequently causes multiorgan affection and decrease in quality of life. Global assessment and care of these patients require a multidisciplinary approach, but access to focused clinics is limited given their scarcity and location in major cities, as well as mobility and transportation challenges that frequently affect these patients. Thus, we established a multispecialty GVHD telehealth (TH) clinic and hypothesized that a virtual platform will expand access to clinical care in children and adults.

Correlation Between CardioMEMS and HeartLogic in Predicting Heart Failure Events.

A 59-year-old male was admitted with acute on chronic decompensated heart failure. Review of his CardioMEMS (Abbott Laboratories, Atlanta, Georgia) device and HeartLogic (Boston Scientific, Marlborough, Massachusetts) index were helpful in guiding management of his volume status. This paper highlights the correlation between 2 monitoring systems which could be used to predict heart failure events.

Abiotic and bioaugmented granular activated carbon for the treatment of 1,4-dioxane-contaminated water.

1,4-Dioxane is a probable human carcinogen and an emerging contaminant that has been detected in surface water and groundwater resources. Many conventional water treatment technologies are not effective for the removal of 1,4-dioxane due to its high water solubility and chemical stability. Biological degradation is a potentially low-cost, energy-efficient approach to treat 1,4-dioxane-contaminated waters.

Objectives: (1) Examine pharmacists' role in addressing care coordination and adherence challenges for patients taking Long-Acting Injectable (LAI) antipsychotics; and (2) explore patients' medication use experiences with LAI antipsychotics and educational needs.

Outcomes of a health coaching intervention delivered by medical students for older adults with uncontrolled type 2 diabetes.

Effective strategies are needed to address the health behaviors of older patients with diabetes. One approach is health coaching, the practice of health education and health promotion through a structured partnership designed to enhance well-being and facilitate the achievement of individuals' health-related goals. The aim of this study was to describe the development of a pilot health coaching curriculum, investigate its effects on geriatric patient outcomes, and examine qualitative feedback by older patients and medical students to the curriculum.

PUMA regulates germ cell loss and primordial follicle endowment in mice.

The number of primordial follicles initially established within the ovary is influenced by the extent of germ cell death during foetal ovarian development, but the mechanisms that mediate this death have not been fully uncovered. In this study, we identified BBC3 (PUMA) (p53 upregulated modulator of apoptosis, also known as BCL2-binding component 3), a pro-apoptotic BH3-only protein belonging to the BCL2 family, as a critical determinant of the number of germ cells during ovarian development. Targeted disruption of the Bbc3 gene revealed a significant increase in the number of germ cells as early as embryonic day 13.

The dynamics of the primordial follicle reserve.

The female germline comprises a reserve population of primordial (non-growing) follicles containing diplotene oocytes arrested in the first meiotic prophase. By convention, the reserve is established when all individual oocytes are enclosed by granulosa cells. This commonly occurs prior to or around birth, according to species.

GDF9 modulates the reproductive and tumor phenotype of female inha-null mice.

Intraovarian factors play important roles in coordinating germ cell and somatic cell growth in the ovary. Prior to the onset of gonadotropin stimulation and reproductive cyclicity, follicle development is dependent upon locally produced growth factors, such as the transforming growth factor beta family members inhibin, activin, and GDF9. In the absence of inhibin in prepubertal mice (Inha(-/-)), there are marked alterations in preantral follicle growth, but no evidence of ovarian tumors characteristic of adult Inha-null mice.

High quality p-type Ag-doped ZnO thin films achieved under elevated growth temperatures.

By correlating the effects of substrate temperature, oxygen pressure and laser energy on the electrical and microstructural properties of Ag-doped ZnO films grown on a sapphire (0001) substrate, p-type conductivity is achieved under various substrate temperatures in the wide range of 250-750 °C. All of the samples were deposited by pulsed-laser deposition under various designed conditions. Hall measurements indicate that the best conductivity is achieved in Ag-ZnO films under a substrate temperature of 500 °C, a partial oxygen pressure of 250-300 mTorr and laser energy between 330 and 345 mJ.

Loss of gremlin delays primordial follicle assembly but does not affect female fertility in mice.

The transforming growth factor beta (TGFB) protein family is renowned for its diverse roles in developmental biology including reproduction. Gremlin is a member of the differential screening-selected gene aberrative in neuroblastoma (DAN)/cerberus family of bone morphogenetic protein (BMP) antagonists. Recent studies on gremlin focus on its involvement in embryonic skeletal, lung, and kidney development.

Regulatory roles of transforming growth factor beta family members in folliculogenesis.

Bidirectional signaling between the oocyte and surrounding somatic cells is absolutely essential for successful germ cell development in mammals. Oocytes secrete proteins that are necessary for granulosa cells growth and differentiation, whilst granulosa cells regulate oocyte development and integrate ovarian function with the rest of the body by orchestrating gonadal steroidogenesis. The importance of communication between the oocyte and granulosa cells is highlighted by genetic deletion of members of the transforming growth factor beta (TGFβ) family and their downstream signaling components.

Defective gonadotropin-dependent ovarian folliculogenesis and granulosa cell gene expression in inhibin-deficient mice.

Inhibin-α knockout (Inha-/-) female mice develop sex cord-stromal ovarian cancer with complete penetrance and previous studies demonstrate that the pituitary gonadotropins (FSH and LH) are influential modifiers of granulosa cell tumor development and progression in inhibin-deficient females. Recent studies have demonstrated that Inha-/- ovarian follicles develop precociously to the early antral stage in prepubertal mice without any increase in serum FSH. These studies suggest that in the absence of inhibins, granulosa cells differentiate abnormally and thus at sexual maturity may undergo an abnormal response to gonadotropin signaling contributing to tumor development.

Loss of inhibin alpha uncouples oocyte-granulosa cell dynamics and disrupts postnatal folliculogenesis.

Targeted disruption of the inhibin alpha gene (Inha(-)(/)(-)) in mice results in an ovarian phenotype of granulosa cell tumors that renders the animals infertile. Little is known about the reproductive defects prior to tumor development. Here, we report novel data on early follicle dynamics in Inha(-)(/)(-) mice, which demonstrate that inhibin alpha has important consequences upon follicle development.

Islet beta-cells deficient in Bcl-xL develop but are abnormally sensitive to apoptotic stimuli.

Objective: Bcl-xL is an antiapoptotic member of the Bcl-2 family of proteins and a potent regulator of cell death. We investigated the importance of Bcl-xL for beta-cells by deleting the Bcl-x gene specifically in beta-cells and analyzing their survival in vivo and in culture.

Research Design And Methods: Islets with beta-cells lacking the Bcl-x gene were assessed in vivo by histology and by treatment of mice with low-dose streptozotocin (STZ).

A new 'total' activin B enzyme-linked immunosorbent assay (ELISA): development and validation for human samples.

Background And Objective: There are currently no sensitive and specific assays for activin B that could be utilized to study human biological fluids. The aim of this project was to develop and validate a 'total' activin B ELISA for use with human biological fluids and establish concentrations of activin B in the circulation and fluids from the reproductive organs.

Design: The new ELISA was validated and then used to measure activin B levels in the circulation of healthy participants, IVF patients, pregnant women and in ovarian follicular fluid and seminal plasma.

Differential expression and functional characterization of luteinizing hormone receptor splice variants in human luteal cells: implications for luteolysis.

The human LH receptor (LHR) plays a key role in luteal function and the establishment of pregnancy through its interaction with the gonadotropins LH and human chorionic gonadotropin. We previously identified four splice variants of the LHR in human luteinized granulosa cells (LGCs) and corpora lutea (CL). Real-time quantitative PCR revealed that expression of the full-length LHR (LHRa) and the most truncated form (LHRd) changed significantly in CL harvested at different stages of the ovarian cycle (P < 0.

Activin A reduces luteinisation of human luteinised granulosa cells and has opposing effects to human chorionic gonadotropin in vitro.

The transition of the dominant follicle into the corpus luteum is of fundamental reproductive importance. Luteinisation involves disparate changes in the gene expression of follicular granulosa cells that differentiate into the granulosa-lutein cells of the corpus luteum after the gonadotrophin surge. We have shown that activin and human chorionic gonadotropin (hCG) have opposing effects during luteolysis.

HCG up-regulates hypoxia inducible factor-1 alpha in luteinized granulosa cells: implications for the hormonal regulation of vascular endothelial growth factor A in the human corpus luteum.

Vascular endothelial growth factor (VEGF)-dependent angiogenesis is essential for normal luteal development. Although it is believed that hypoxia is the primary inducer of VEGF, in the corpus luteum it is up-regulated by human chorionic gonadotrophin (hCG). As hypoxia-inducible factor (HIF)1A has been shown to regulate VEGFA under ligand-stimulated conditions, we hypothesized that the effect of hCG on luteal VEGFA was mediated through HIF1A.

Novel regulated expression of the SLIT/ROBO pathway in the ovary: possible role during luteolysis in women.

The human corpus luteum (CL) undergoes luteolysis, associated with marked tissue and vascular remodeling, unless conception occurs and the gland is rescued by human chorionic gonadotropin (hCG). In Drosophila the Slit gene product, a secreted glycoprotein, acts as a ligand for the roundabout (robo) transmembrane receptor. Together they influence the guidance and migration of neuronal and nonneuronal cells.

Expression and regulation of oestrogen receptors in the human corpus luteum.

The molecular mechanisms underlying the control of corpus luteum lifespan in women are not fully understood. Oestradiol has various luteolytic, or luteotrophic, functions in some species, and as it is synthesised within the human corpus luteum, it is an excellent candidate molecule to be a paracrine regulator of luteal function. This study aimed to comprehensively investigate the expression, regulation and effects of oestrogen receptors (ER) in human luteal cells.

Role of luteal glucocorticoid metabolism during maternal recognition of pregnancy in women.

The human corpus luteum (hCL) is an active, transient, and dynamic endocrine gland. It will experience extensive tissue and vascular remodeling followed by 1) demise of the whole gland without any apparent scarring or 2) maintenance of structural and functional integrity dependent on conceptus-derived human chorionic gonadotropin (hCG). Because cortisol has well-characterized roles in tissue remodeling and repair, we hypothesized that it may have a role in controlling luteal dissolution during luteolysis and would be locally produced toward the end of the luteal cycle.

In vitro evidence suggests activin-A may promote tissue remodeling associated with human luteolysis.

Luteolysis in women is associated with an up-regulation of the expression and activity of matrix metalloproteinase-2 (MMP-2), which is inhibited by human chorionic gonadotropin (hCG) during maternal recognition of pregnancy. Because the primary source of MMP-2 is fibroblasts that do not express LH/hCG receptors, we aimed to investigate the regulation of MMP-2. Women with regular cycles having hysterectomy for nonmalignant conditions and women undergoing oocyte retrieval for assisted conception were used in this current study.

From aging . . . to saging- the Ohio State Senior Partners Program: longitudinal and experiential geriatrics education.

Ohio State College of Medicine began its Senior Partners Program (SPP) in 2001 as part of its commitment to integrate geriatric education throughout all four years of the medical curriculum. For participating senior partners and medical students, the SPP has signified a journey through a continuum of aging. Initial evaluations suggest that students have gained appropriate knowledge, skills, and attitudes to care for seniors responsively and cost effectively.
