donor retention

Susan Y Friedman, Mitchell T Rabkin
Hospital boards address quality of care and patient safety as well as financial performance through long-accepted practices. By contrast, a hospital's administrative operations and institutional culture are not usually subject to such detailed scrutiny. Yet, despite a healthy bottom line and patient commendations, hospital personnel can be underperforming, burdened with poor morale, and suffering from less than optimal leadership, unwarranted inefficiency, and ethically questionable management practices. The resulting employee dissatisfaction or disengagement can affect productivity, quality, turnover, innovation, patient and donor attraction and retention, public image, etc...

The advancement of nanotechnology toward more sophisticated bioinspired approaches has highlighted the gap between the advantages of biomimetic and biohybrid platforms and the availability of manufacturing processes to scale up their production. Though the advantages of transferring biological features from cells to synthetic nanoparticles for drug delivery purposes have recently been reported, a standardizable, batch-to-batch consistent, scalable, and high-throughput assembly method is required to further develop these platforms...

OBJECTIVES: The present study aimed to gain more insight into, and summarise, blood donation determinants among migrants or minorities of Sub-Saharan heritage by systematically reviewing the current literature. BACKGROUND: Sub-Saharan Africans are under-represented in the blood donor population in Western high-income countries. This causes a lack of specific blood types for transfusions and prevention of alloimmunisation among Sub-Saharan African patients. METHODS/MATERIALS: Medline, EMBASE, PsycINFO and BIOSIS were searched for relevant empirical studies that focused on barriers and facilitators of blood donation among Sub-Saharan Africans in Western countries until 22 June 2017...

Denture adhesives (DA) improve the retention and stability of ill-fitting dentures, especially for older adults. These materials should be biocompatible, i.e., they cannot cause undesired biological responses and be non-cytotoxic to oral tissues. However, in vitro testing of DA biocompatibility employing primary cell culture may possibly be affected by other factors, such as the donor age. OBJECTIVE: To compare the cytotoxicity of three different denture adhesives when assessed in primary gingival fibroblasts from a young donor or from an older donor, as well as the release of the basic fibroblast growth factor (bFGF), and the inflammatory response marker interleukin-6 (IL-6)...

Induced pluripotent stem cells (iPSCs) avoid many of the restrictions that hamper the application of human embryonic stem cells: limited availability of source material due to legal restrictions in some countries, immunogenic rejection and ethical concerns. Also, the donor's clinical phenotype is often known when working with iPSCs. Therefore, iPSCs seem ideal to tackle the two biggest tasks of regenerative medicine: degenerative diseases with genetic cause (e.g., Duchenne's muscular dystrophy) and organ replacement in age-related diseases (e...

The enantiomer separation of a number of racemic 7-[(1-alkylpiperidin-3-yl)methoxy]coumarin derivatives, some of which show outstanding in vitro multitarget neuroprotective activities, was successfully achieved on a polysaccharide-based chiral stationary phase, bearing amylose tris(3,5-dimethylphenylcarbamate) as chiral selector, in normal polar mode (methanol and acetonitrile as the mobile phases). The majority of the screened selectands, especially those bearing 1-(3-X-benzyl)piperidin-3-yl moieties, showed baseline enantiomer separations, and compound 8 (X = NO2 ) was the best resolved (α = 2...

Simultaneous removal of selenite and tellurite from synthetic wastewater was achieved through microbial reduction in a lab-scale upflow anaerobic sludge blanket reactor operated with 12 h hydraulic retention time at 30 °C and pH 7 for 120 days. Lactate was supplied as electron donor at an organic loading rate of 528 or 880 mg COD L-1 day-1. The reactor was initially fed with a synthetic influent containing 0.05 mM selenite and tellurite each (phase I, day 1-60) and subsequently with 0.1 mM selenite and tellurite each (phase II, day 61-120)...

Changes in splicing are known to affect the function and regulation of genes. We analyzed splicing events that take place during the postnatal development of the prefrontal cortex in humans, chimpanzees, and rhesus macaques based on data obtained from 168 individuals. Our study revealed that among the 38,822 quantified alternative exons, 15% are differentially spliced among species, and more than 6% splice differently at different age. Mutations in splicing acceptor and/or donor sites might explain more than 14% of all splicing differences among species and up to 64% of high-amplitude differences...

The liver has unique microenvironment which is known to induce tolerance of cytolytic CD8+ T cells to hepatic and extra hepatic antigens, resulting in persistence of infection of the liver by the hepatitis B and C viruses. However, under some conditions, functional immune responses can be elicited in the liver in particular to show preferential retention of activated CD8+ T cells. It is not clear whether this retention depends on the type of the exogenous immunostimulatory or the endogenous innate immune cells...

Regulation of gene expression by DNA methylation in gene promoter regions is well studied; however, the effects of methylation in the gene body (exons and introns) on gene expression are comparatively understudied. Recently, hypermethylation has been implicated in the inclusion of alternatively spliced exons; moreover, exon recognition can be enhanced by recruiting the methyl-CpG-binding protein (MeCP2) to hypermethylated sites. This study examines whether the methylation status of an intron is correlated with how frequently the intron is retained during splicing using DNA methylation and RNA sequencing data from breast cancer tissue specimens in The Cancer Genome Atlas...

BACKGROUND: Short messaging service (SMS) is routinely used by blood collection agencies to remind donors about appointments but has been applied less frequently in interventions to increase return behavior. This study aimed to investigate whether receipt of a personalized postdonation SMS promoted donor retention. STUDY DESIGN AND METHODS: A postdonation SMS was sent to 2605 whole blood donors who had donated at one of six donor centers in Australia from April to July 2015 and left without making a forward appointment...

New regulations require living kidney donor (LKD) follow-up for two years, but donor retention remains poor. Electronic communication (e.g. text messaging, e-mail) might improve donor retention. To explore the possible impact of electronic communication, we recruited LKDs to participate in an exploratory study of communication via telephone, e-mail, or text messaging post-donation; communication through this study was purely optional and did not replace standard follow-up. Of 69 LKDs recruited, 3% requested telephone call, 52% e-mail, and 45% text messaging...

BACKGROUND: Utilization of unrelated donors and cord blood units (CBUs) for allogeneic hematopoietic cell transplantation continues to increase. Understanding the practices of donor selection by transplant centers is critical for unrelated donor registries and cord blood banks to optimize registry composition and inventory to meet patient need. STUDY DESIGN AND METHODS: Unrelated donor and CBU selection practices of Canadian transplant centers served by Canadian Blood Services' OneMatch Stem Cell & Marrow Network (OM) were reviewed, including HLA match level, locus of disparity, age, sex, and product choice (donor vs...

BACKGROUND AND OBJECTIVES: Effective recruitment and retention of male donors are vital for the ongoing provision of blood products. Compared with females, male donors are less likely to be medically deferred or experience vasovagal reactions and are typically preferred for plasmapheresis donation in voluntary non-remunerated settings. However, females outnumber males among donors aged under 40 years. This systematic review aimed to synthesize evidence and identify key motivators for blood donation among males to inform targeted recruitment/retention campaigns...

A denitrifying pilot plant was designed, constructed and operated for more than five months. The plant treated domestic wastewater with high ammonium nitrogen concentration, which had previously undergone an anaerobic process at 18 °C. The process consisted of one biofilter with 2 h of hydraulic retention time for denitritation. Different synthetic nitrite concentrations were supplied to the anoxic reactor to simulate the effluent of a nitritation process. This work investigates the advanced denitritation of wastewater using the organic matter and other alternative electron donors present in an anaerobic treatment process effluent: methane and sulfide...

The synthesis and electrocatalytic reduction of dioxygen by a molecular manganese(III) complex with a tetradentate dianionic bipyridine-based ligand is reported. Electrochemical characterization indicates a Nernstian dependence on the added proton source for the reduction of Mn(III) to Mn(II). The resultant species is competent for the reduction of dioxygen to H2 O2 with 81 ± 4% Faradaic efficiency. Mechanistic studies suggest that the catalytically active species has been generated through the interaction of the added proton donor and the parent Mn complex, resulting in the protonation of a coordinated phenolate moiety following the single-electron reduction, generating a neutral species with a vacant coordination site at the metal center...

Acute graft-versus-host disease (aGVHD) remains a clinical challenge and a major source of morbidity and mortality following allogeneic hematopoietic stem cell transplantation (allo-HSCT). Dimethyl fumarate (DMF), an activator of Nrf2, has been shown to have anti-inflammatory and immunomodulatory properties without significant immunosuppression. We therefore hypothesized that DMF could be potentially harnessed for the treatment of aGVHD with retention of graft-versus-tumor effect. In this study, we showed that DMF significantly inhibited alloreactive T cell responses in vitro in mixed lymphocyte reaction assay...

A projected shortage of hematopoietic cell transplantation (HCT) health professionals was identified as a major issue during the National Marrow Donor Program/Be The Match System Capacity Initiative. Work-related distress and work-life balance were noted to be potential barriers to recruitment/retention. This study examined these barriers and their association with career satisfaction across HCT disciplines. A cross-sectional, 90-item, web-based survey was administered to advanced practice providers, nurses, physicians, pharmacists, and social workers in 2015...
