In 1996, Glaxo Wellcome offered to donate up to a million treatment courses annually of Malarone, a new antimalarial, with a view to reducing the global burden of malaria. The Malarone Donation Programme (MDP) was established the following year. Eight pilot sites were selected in Kenya and Uganda to develop and evaluate an effective, locally sustainable donation strategy that ensured controlled and appropriate use of Malarone. The pilot programme targeted individuals who had acute uncomplicated Plasmodium falciparum malaria that had not responded to first-line treatments with chloroquine or sulfadoxine-pyrimethamine. Of the 161 079 patients clinically diagnosed at the pilot sites as having malaria, 1101 (0.68%) met all the conditions for participation and received directly observed treatment with Malarone. MDP had a positive effect at the pilot sites by improving the diagnosis and management of malaria. However, the provision of Malarone as a second-line drug at the district hospital level was not an efficient and effective use of resources. The number of deaths among children and adults ineligible for MDP at the pilot sites suggested that high priority should be given to meeting the challenges of malaria treatment at the community level.

Mentorship is crucial for academic productivity and advancement for clinical and translational (CT) science faculty. However, little is known about the long-term effects of mentor training programs. The University of California, San Francisco (UCSF), Clinical and Translational Science Institute launched a Mentor Development Program (MDP) in 2007 for CT faculty. We report on an evaluation of the first three cohorts of graduates from the MDP. In 2010, all Mentors in Training (MITs) who completed the MDP from 2007 to 2009 (n= 38) were asked to complete an evaluation of their mentoring skills and knowledge; all MITs (100%) completed the evaluation. Two-thirds of MDP graduates reported that they often apply knowledge, attitudes, or skills obtained in the MDP to their mentoring. Nearly all graduates (97%) considered being a mentor important to their career satisfaction. Graduates were also asked about the MDP's impact on specific mentoring skills; 95% agreed that the MDP helped them to become a better mentor and to focus their mentoring goals. We also describe a number of new initiatives to support mentoring at UCSF that have evolved from the MDP. To our knowledge, this is the first evaluation of the long-term impact of a mentor training program for CT researchers. © 2012 Wiley Periodicals, Inc.

Abstract Mentorship is crucial for academic productivity and advancement for clinical and translational (CT) science faculty. However, little is known about the long‐term effects of mentor training programs. The University of California, San Francisco (UCSF), Clinical and Translational Science Institute launched a Mentor Development Program (MDP) in 2007 for CT faculty. We report on an evaluation of the first three cohorts of graduates from the MDP. In 2010, all Mentors in Training (MITs) who completed the MDP from 2007 to 2009 (n= 38) were asked to complete an evaluation of their mentoring skills and knowledge; all MITs (100%) completed the evaluation. Two‐thirds of MDP graduates reported that they often apply knowledge, attitudes, or skills obtained in the MDP to their mentoring. Nearly all graduates (97%) considered being a mentor important to their career satisfaction. Graduates were also asked about the MDP's impact on specific mentoring skills; 95% agreed that the MDP helped them to become a better mentor and to focus their mentoring goals. We also describe a number of new initiatives to support mentoring at UCSF that have evolved from the MDP. To our knowledge, this is the first evaluation of the long‐term impact of a mentor training program for CT researchers. Clin Trans Sci 2012; Volume 5: 362–367 PMID:22883616

Mentoring is a critical component of career development and success for clinical translational science research faculty. Yet few programs train faculty in mentoring skills. We describe outcomes from the first two faculty cohorts who completed a Mentor Development Program (MDP) at UCSF. Eligibility includes having dedicated research time, expertise in a scientific area and a desire to be a lead research mentor. A post-MDP survey measured the program's impact on enhancement of five key mentoring skills, change in the Mentors-in-Training (MIT) self-rated importance of being a mentor to their career satisfaction, and overall confidence in their mentoring skills. Since 2007, 29 MITs participated in and 26 completed the MDP. Only 15% of the MITs reported any previous mentor training. Overall, 96% of MITs felt that participation in the MDP helped them to become better mentors. A majority reported a significant increase in confidence in mentoring skills and most reported an increased understanding of important mentoring issues at UCSF. MITs reported increased confidence in overall and specific mentoring skills after completion of the MDP. The MDP can serve as a model for other institutions to develop the next generation of clinical-translational research mentors.

This study investigated whether multidisciplinary disease management programs (MDPs) exert the same effects in heart failure (HF) patients across risk levels stratified by galectin-3 (Gal-3) level and what factors are associated with inadequate effectiveness of MDP. We used a longitudinal follow-up design based on a previous randomized trial. A total of 355 stabilized hospitalized HF patients were enrolled. The effects of MDP on death and HF-related rehospitalization were analyzed according to Gal-3 levels. During the 4-year follow-up, Gal-3 levels predicted mortality and composite events (p < .001). Multivariable analysis demonstrated the event-lowering effect of MDP (hazard ratio [HR] = 0.49, p = .001 for death and HR = 0.50, p < .001 for composite events). However, the effect of MDP was inadequate for those with high Gal-3 levels (≥17.9 ng/ml), whose 4-year composite event rate was 43% in the MDP arm. Further analysis showed that, in patients with Gal-3 ≥ 17.9 ng/ml, the independent factors associated with a high composite event rate were no MDP, older age, worse New York Heart Association functional class, no angiotensin-converting enzyme inhibitor or angiotensin II receptor blocker use, higher predischarge natriuretic peptide levels, and wider QRS complexes. The effectiveness of MDP for HF patients at high risk was inadequate. Our findings identified the characteristics of these MDP nonresponders. Better integration of advanced care plans based on strategies guided by Gal-3 level is needed to improve care quality. © The Author(s) 2016.

This paper presents an optimization model for selection of pavement maintenance intervention using a theory of Markov Decision Processes (MDP). There are some particular characteristics of the MDP developed in this paper which distinguish it from other similar studies or optimization models intended for pavement maintenance policy development. These unique characteristics include a direct inclusion of constraints into the formulation of MDP, the use of an average cost method of MDP, and the policy development process based on the dual linear programming solution. The limited information or discussions that are available on these matters in terms of stochastic based optimization model in road network management motivates this study. This paper uses a data set acquired from road authorities of state of Victoria, Australia, to test the model and recommends steps in the computation of MDP based stochastic optimization model, leading to the development of optimum pavement maintenance policy.

We consider a discrete-time constrained discounted Markov decision process (MDP) with Borel state and action spaces, compact action sets, and lower semi-continuous cost functions. We introduce a set of hypotheses related to a positive weight function which allow us to consider cost functions that might not be bounded below by a constant, and which imply the solvability of the linear programming formulation of the constrained MDP. In particular, we establish the existence of a constrained optimal stationary policy. Our results are illustrated with an application to a fishery management problem.

The ability of muramyl dipeptide (MDP), its adjuvant inactive stereoisomer, MDP(D-D), and the non-pyrogenic, adjuvant active analogue, MDP-butyl ester (MDP-BE), to induce in vitro proliferation and/or polyclonal activation (PA) of peripheral blood mononuclear cells (PBMNC) from normal volunteers, was studied. MDP, as well as its two analogues, were incapable of inducing 3H-thymidine uptake or immunoglobulin synthesis in PBMNC cultures from the majority of the individuals tested. However, these muramyl peptides were capable of regulating the in vitro proliferative responses of some individuals to concanavalin A and to soluble antigens of Candida albicans. At the same time, enhancement of the pokeweed mitogen-induced IgA and IgM but not IgG PA was observed with MDP, its adjuvant active analogue MDP-BE, but not with the adjuvant inactive stereoisomer MDP(D-D). Results are discussed with relation to a possible genetic restriction of the responsiveness to MDP. PMID:6744667

To investigate the effects of an experimental 10-methacryloyloxydecyl dihydrogen phosphate (MDP)-based one-step self-etching adhesive (EX adhesive) applied to enamel and dentin on the production of calcium salt of MDP (MDP-Ca salt) and dicalcium phosphate dehydrate (DCPD) at various periods. The EX adhesive was prepared. Bovine enamel and dentin reactants were prepared by varying the application period of the EX adhesive: 0.5, 1, 5, 30, 60 and 1440 min. Enamel and dentin reactants were analyzed using x-ray diffraction and solid-state phosphorus-31 nuclear magnetic resonance (31P NMR). Curvefitting analyses of corresponding 31P NMR spectra were performed. Enamel and dentin developed several types of MDP-Ca salts and DCPDs with amorphous and crystalline phases throughout the application period. The predominant molecular species of MDP-Ca salt was determined as the monocalcium salt of the MDP monomer. Dentin showed a faster production rate and greater produced amounts of MDP-Ca salt than did enamel, since enamel showed a knee-point in the production rate of the MDP-Ca salt at the application period of 5 min. In contrast, enamel developed greater amounts of DCPD than did dentin and two types of DCPDs with different crystalline phases at application periods > 30 min. The amounts of MDP-Ca salt developed during the 30-s application of the EX adhesive on enamel and dentin were 7.3 times and 21.2 times greater than DCPD, respectively. The MDP-based one-step adhesive yielded several types of MDP-Ca salts and DCPD with an amorphous phase during the 30-s application period on enamel and dentin.

Currently, the functional monomer 10-methacryloyloxy-decyl-dihydrogen-phosphate (10-MDP) was documented to chemically bond to zirconia ceramics. However, little research has been conducted to unravel the underlying mechanisms. This study aimed to assess the chemical interaction and to demonstrate the mechanisms of coordination between 10-MDP and zirconium oxide using 1H and 31P magic angle spinning (MAS) nuclear magnetic resonance (NMR) and two dimensional (2D) 1H → 31P heteronuclear correlation (HETCOR) NMR. In addition, shear bond-strength (SBS) tests were conducted to determine the effect of 10-MDP concentration on the bonding effectiveness to zirconia. These SBS tests revealed a 10-MDP concentration-dependent SBS with a minimum of 1-ppb 10-MDP needed. 31P-NMR revealed that one P-OH non-deprotonated of the PO3H2 group from 10-MDP chemically bonded strongly to zirconia. 1H-31P HETCOR NMR indicated that the 10-MDP monomer can be adsorbed onto the zirconia particles by hydrogen bonding between the P=O and Zr-OH groups or via ionic interactions between partially positive Zr and deprotonated 10-MDP (P-O−). The combination of 1H NMR and 2D 1H-31P HETCOR NMR enabled to describe the different chemical states of the 10-MDP bonds with zirconia; they not only revealed ionic but also hydrogen bonding between 10-MDP and zirconia.

This study investigated the effect of continuous application of 10-methacryloyloxydecyldihydrogen phosphate (MDP)-containing primer and luting resin cement on bond strength to tribochemical silica-coated yttria-stabilized tetragonal zirconia polycrystal (Y-TZP). Forty bovine teeth and Y-TZP specimens were prepared. The dentin specimens were embedded in molds, with one side of the dentin exposed for cementation with the zirconia specimen. The Y-TZP specimen was prepared in the form of a cylinder with a diameter of 3 mm and a height of 10 mm. The bonding surface of the Y-TZP specimen was sandblasted with silica-coated aluminium oxide particles. The forty tribochemical silica-coated Y-TZP specimens were cemented to the bovine dentin (4 groups; n = 10) with either an MDP-free primer or an MDP-containing primer and either an MDP-free resin cement or an MDP-containing resin cement. After a shear bond strength (SBS) test, the data were analyzed using 1-way analysis of variance and the Tukey test (α = 0.05). The group with MDP-free primer and resin cement showed significantly lower SBS values than the MDP-containing groups ( p < 0.05). Among the MDP-containing groups, the group with MDP-containing primer and resin cement showed significantly higher SBS values than the other groups ( p < 0.05). The combination of MDP-containing primer and luting cement following tribochemical silica coating to Y-TZP was the best choice among the alternatives tested in this study.

Expenses for marker assays are the major costs in marker-assisted backcrossing programs for the transfer of target genes from a donor into the genetic background of a recipient genotype. Our objectives were to (1) investigate the effect of employing sequentially increasing marker densities over backcross generations on the recurrent parent genome (RPG) recovery and the number of marker data points (MDP) required, and (2) determine optimum designs for attaining RPG thresholds of 93-98% with a minimum number of MDP. We simulated the introgression of one dominant target gene for genome models of sugar beet (Beta vulgaris L.) and maize (Zea mays L.) with varying marker distances of 5-80 cM and population sizes of 30-250 plants across BC(1) to BC(3) generations. Employing less dense maps in early backcross generations resulted in savings of over 50% in the number of required MDP compared with using a constant set of markers and was accompanied only by small reductions in the attained RPG values. The optimum designs were characterized by increasing marker densities and increasing population sizes in advanced generations for both genome models. We conclude that increasing simultaneously the marker density and the population size from early to advanced backcross generations results in gene introgression with a minimum number of required MDP.

Courses and special programs to train supervisors at Marshall Space Flight Center (MSFC) were to determine the adequacy of the present MSFC Supervisory Training Program and to recommend changes, if appropriate. The content, procedures, and student evaluations of the required Office of Personnel Management (OPM) 80 hours training for supervisors, the optional 120 hours, the MSFC Management Development Program (MDP), NASA's Management Education Program (MEP), various OPM and special contract programs, pertinent procedural guidelines, regulations, and letters, as well as various MSFC computer reports which indicate who took what training were analyzed. Various interviews with MSFC personnel involved in training are included. Recommendations consist of: (1) the choice of courses selected for the basic required OPM 80 hours be improved; (2) the optional 120 hours be discontinued and a shorter module be developed dealing with managerial decision making and human relations skills; (3) the MDP and MEP be continued as at present; and (4) that a broad array of developmental strategies be incorporated to provide a variety of opportunities for supervisory improvement.

Personalized nutritional strategies to treat obesity may specifically influence inflammatory markers, in addition to reduce body weight. In the present study, we evaluated the effect of a hypocaloric diet based on a Mediterranean dietary pattern (MDP) on nutritional status as well as on plasma concentrations of retinol binding protein-4 (RBP4) and other proinflammatory markers. Fourty-one subjects (24F/17M; age: 37 ± 7 years; BMI: 32.2 ± 3.9 kg/m²) were assigned to follow a MDP within a caloric-restricted diet over an 8-week period. Anthropometrical, clinical, and biochemical variables were measured at baseline and endpoint after the nutritional program. Dietary intervention resulted in a mean weight loss of -4.4 ± 2.5 kg (P < 0.001) and marked reductions (P < 0.05) in plasma concentrations of RBP4, leptin, C-reactive protein, complement C3, and tumor necrosis factor-alpha (TNFα). Individuals with a higher adherence to the MDP during the nutritional intervention presented differentially higher reductions (P < 0.05) in plasma RBP4, IL6, and TNFα. In addition, the increase in the Mediterranean diet score from baseline was a significant and independent predictor factor for the decrease in plasma RBP4 concentration (P < 0.05). In conclusion, our findings suggest that following a hypocaloric diet accompanying a high adherence to a MDP resulted in specific reductions on proinflammatory markers, in addition to a significant improvement in some metabolic syndrome features induced by weight loss, which could be a good combined strategy to treat obesity as well as related metabolic and inflammatory disorders.

To evaluate the 3-methacryloyloxypropyltrimethoxysilane (MPS)- and 10-methacryloyloxydecyl-dihydrogen-phosphate (MDP)-base primers, in their single or sequential applications, with regard to modifying zirconia surfaces and improving resin-zirconia adhesion. Zirconia disks received different treatments: without primer (Zr), MPS-base primer (S), MDP-base primer (M), MPS/MDP mixture (SMmix), MPS followed by MDP (SM), and MDP followed by MPS (MS). The compositions and chemical interactions of the coatings to zirconia were analyzed using time-of-flight secondary ion mass spectrometry (ToF-SIMS) and reconstructed 3D ion images. Surface wettability of these coatings to water and resin adhesive was assessed. The shear bond strength (SBS) between resin and the treated zirconia was also examined before and after thermocycling. Groups S and MS presented substantial OH - ions in the coatings and zirconia substrate. PO 2 - and PO 3 - fragments existed in all MDP-treatment groups with various proportions and distributions, while groups M and SM showed higher proportions of PO 3 - and the zirconium phosphate related ions. In 3D ion images, PO 3 - in groups M and SM was denser and segregated to the interface, but was dispersed or overlaid above PO 2 - in SMmix and MS. All the primers increased the surface wettability to water and resin, with M and SM presenting superhydrophilic surfaces. All MDP-treatment groups showed improved SBS before thermocycling, while M and SM retained higher SBS after this. The MDP-base primer shows a relevant function in facilitating POZr bonding and enhancing resin-zirconia bonding. The co-treated MPS impairs the chemical activity of MDP, especially if it is the final coat. Copyright © 2017 The Academy of Dental Materials. Published by Elsevier Ltd. All rights reserved.

The present study was aimed to develop a novel textile product through bio modification of cotton and micro-denier polyester with sericin (Sn) against bacterial and fungal growth. The authors extracted and purified Sn from silk yellow cocoons. Sn solution (10 g/L) was incorporated into the 100% cotton (C), 100% micro-denier polyester (MDP) and 65/35 micro-denier polyester/cotton (MDP/C) in a padding mangle by a 2-dip/2-nip process and fabrics were analysed by Field-Emission scanning electron microscope. Fabrics were divided into six groups such as untreated groups (C, MDP and MDP/C) and Sn-treated groups (Sn + C, Sn + MDP and Sn + MDP/C) and then underwent organoleptic evaluation and as well as anti-bacterial (Staphylococcus aureus and Escherichia coli) and anti-fungal (Aspergillus niger and Trichoderma harzianum) activities. Sn treated fabrics were found to show the presence of Sn by scanning electron micrographs and also attained high organoleptic score from the panel members. In addition, the Sn-treated fabrics displayed outstanding anti bacterial and anti fungal properties in terms of both qualitative and quantitative analysis. Sn + MDP/C fabrics have shown potential reduction in bacterial and fungal growth when compared with other treated and untreated fabrics. Hence, this study suggests that bio modification of C, MDP and MDP/C with Sn may make them ideal candidate for their application in medical textiles against pathogens.
Experimental drug-induced changes in renal function and biodistribution of /sup 99m/Tc-MDP
DOE Office of Scientific and Technical Information (OSTI.GOV)
McAfee, J.G.; Singh, A.; Roskopf, M.
Increased renal uptake of /sup 99m/Tc methylene diphosphonate (MDP) was observed irregularly in rats after methotrexate, vincristine or gentamicin, administered separately. Cisplatin regularly induced a dose-related increased MDP uptake which correlated with the degree of tubular damage histologically. The augmented MDP renal uptake was not consistently accompanied by a decreased clearance of simultaneously injected I-131 Hippuran, particularly at lower drug dose levels. This observation agreed with previous evidence that the mechanisms of tubular transport of diphosphonates and organic acids like Hippuran are different. At higher dose levels, the augmented MDP uptake was accompanied by increased renal calcium, hypophosphatemia, elevated serummore » urea nitrogen and creatinine, and only occasional, mild hypercalcemia. The magnitude of the increased renal uptake of MDP observed could not be explained by alterations in iron metabolism or by dehydration. Drug-induced renal retention of MDP by a factor of 2 or more above normal appears to be a useful indicator of tubular damage when other parameters of renal function are sometimes normal.« less
An overview of the roles and responsibilities of Chinese medical colleges in body donation programs.

The use of human tissue is critical for gross anatomy education in the health professions. Chinese medical colleges have faced a shortage of anatomical specimens over the past decade. While body donation plays an important role in overcoming this gap, this practice has only recently been introduced in China, and the donation rate is relatively low and fraught with a number of difficulties. In the past, traditional Chinese culture focused on preserving the human body intact, which often limited body donation. In recent years, the public has become more open toward body donation. At Nanjing Medical University, only 20 bodies were donated in 2001. After the university became involved in an organized body donation program, this number increased to 70 donated bodies per year (2007 to 2012). This article describes and reviews Chinese medical colleges as a special case study among body donation programs, particularly in terms of the multiple responsibilities and roles that such institutions must assume in the course of adopting these programs. Medical colleges in China must serve as advocates, coordinators, builders, managers, educators, and beneficiaries in undertaking body donation programs. It is important for medical colleges to recognize these pluripotent roles and educate the public in order to promote body donation programs. This case study may also effectively guide and encourage Chinese medical colleges in refining their own body donation programs in the future. © 2013 American Association of Anatomists.
Comprehensive Fault Tolerance and Science-Optimal Attitude Planning for Spacecraft Applications
NASA Astrophysics Data System (ADS)
Nasir, Ali
Spacecraft operate in a harsh environment, are costly to launch, and experience unavoidable communication delay and bandwidth constraints. These factors motivate the need for effective onboard mission and fault management. This dissertation presents an integrated framework to optimize science goal achievement while identifying and managing encountered faults. Goal-related tasks are defined by pointing the spacecraft instrumentation toward distant targets of scientific interest. The relative value of science data collection is traded with risk of failures to determine an optimal policy for mission execution. Our major innovation in fault detection and reconfiguration is to incorporate fault information obtained from two types of spacecraft models: one based on the dynamics of the spacecraft and the second based on the internal composition of the spacecraft. For fault reconfiguration, we consider possible changes in both dynamics-based control law configuration and the composition-based switching configuration. We formulate our problem as a stochastic sequential decision problem or Markov Decision Process (MDP). To avoid the computational complexity involved in a fully-integrated MDP, we decompose our problem into multiple MDPs. These MDPs include planning MDPs for different fault scenarios, a fault detection MDP based on a logic-based model of spacecraft component and system functionality, an MDP for resolving conflicts between fault information from the logic-based model and the dynamics-based spacecraft models" and the reconfiguration MDP that generates a policy optimized over the relative importance of the mission objectives versus spacecraft safety. Approximate Dynamic Programming (ADP) methods for the decomposition of the planning and fault detection MDPs are applied. To show the performance of the MDP-based frameworks and ADP methods, a suite of spacecraft attitude planning case studies are described. These case studies are used to analyze the content and behavior of computed policies in response to the changes in design parameters. A primary case study is built from the Far Ultraviolet Spectroscopic Explorer (FUSE) mission for which component models and their probabilities of failure are based on realistic mission data. A comparison of our approach with an alternative framework for spacecraft task planning and fault management is presented in the context of the FUSE mission.

OBJECTIVE To determine the ultrasonographic appearance of the major duodenal papilla (MDP) in dogs without evidence of hepatobiliary, pancreatic, or gastrointestinal tract disease. ANIMALS 40 adult client-owned dogs examined because of conditions that did not include hepatobiliary, pancreatic, or gastrointestinal tract disease. PROCEDURES Ultrasonographic examination of the MDP was performed. Each MDP was measured in 3 planes. Intraobserver reliability of measurements was determined, and associations between MDP dimensions and characteristics of the dogs were investigated. Histologic examination of longitudinal sections of the MDP was performed for 1 dog to compare the ultrasonographic and histologic appearance. RESULTS The MDP appeared as a layered structure with a hyperechoic outer layer, hypoechoic middle layer, and hyperechoic inner layer that corresponded to the duodenal serosa, duodenal muscularis, and duodenal submucosa, respectively. Layers visible during ultrasonographic examinations were consistent with layers identified histologically. Intraobserver reliability was substantial for each plane of measurement. Mean ± SD length, width, and height of the MDP were 15.2 ± 3.5 mm, 6.3 ± 1.6 mm, and 4.3 ± 1.0 mm, respectively. An increase in body weight of dogs was significantly associated with increased values for all measurements. CONCLUSIONS AND CLINICAL RELEVANCE The ultrasonographic appearance and approximate dimensions of the MDP of dogs without evidence of hepatobiliary, pancreatic, or gastrointestinal tract disease were determined. Additional studies are needed to evaluate possible ultrasonographic lesions of the MDP in dogs with hepatobiliary, pancreatic, or intestinal diseases and to investigate clinical implications of these lesions with regard to diagnosis and prognosis.
Progress Report on Neglected Tropical Disease Drug Donation Programs.

Neglected tropical diseases (NTDs) impose a significant burden on public health, particularly in developing nations. Many can be treated cost-effectively with drugs donated or offered at or below marginal cost. In 2012, the World Health Organization published an NTD roadmap that outlined a strategy for the prevention, control, and eradication of 17 NTDs by 2020. Inspired by this roadmap, executives from 13 pharmaceutical companies, government agencies, and other interested parties signed the London Declaration on Neglected Tropical Diseases in January 2012. In this paper, we will assess progress in meeting commitments on drug donations laid out in the London Declaration. We conducted Medline and LexisNexis searches of peer-reviewed publications and trade journals, as well as product development partnership and government reports. Subsequently, we designed a survey instrument and surveyed 10 company signatories (companies with drug donation programs) to the London Declaration to determine current donations and pledges. Nine of 10 companies with donation programs responded to the survey. The respondents reported substantial progress in meeting the goals laid out in the London Declaration. Survey respondents maintained 17 drug donation programs across 10 disease categories. In 2014, companies donated >1 billion treatments, with a dollar value of nearly $1.5 billion. However, not all donated products were distributed to patients in need. In addition, 4 of the 17 programs were slated to end before 2020, three of the 17 programs did not report explicit program objectives, and 7 of 17 did not measure the impact of programs in terms of numbers of patients treated. None of our survey respondents reported on whether the programs were leading to a reduction in disease prevalence. Donations are a necessary but insufficient condition for patient access to neglected disease drugs. Additional resources must be allocated to ensure delivery of donated products to patients. In addition, drug donation programs should provide explicit descriptions of program objectives, measurements of the impacts of their programs, and extension of all donation commitments through 2020. To achieve this, multiple stakeholders with a vested interest in reducing the burden of neglected diseases must collaborate in a multipronged approach toward NTD elimination.

The donation rate (DR) per million population is not ideal for an efficiency comparison of national deceased organ donation programs. The DR does not account for variabilities in the potential for deceased donation which mainly depends on fatalities from causes leading to brain death. In this study, the donation activity was put into relation to the mortality from selected causes. Based on that metric, this study assesses the efficiency of different donation programs. This is a retrospective analysis of 2001-2015 deceased organ donation and mortality registry data. Included are 27 Council of Europe countries, as well as the USA. A donor conversion index (DCI) was calculated for assessing donation program efficiency over time and in international comparisons. According to the DCI and of the countries included in the study, Spain, France, and the USA had the most efficient donation programs in 2015. Even though mortality from the selected causes decreased in most countries during the study period, differences in international comparisons persist. This indicates that the potential for deceased organ donation and its conversion into actual donation is far from being similar internationally. Compared with the DR, the DCI takes into account the potential for deceased organ donation, and therefore is a more accurate metric of performance. National donation programs could optimize performance by identifying the areas where most potential is lost, and by implementing measures to tackle these issues.

To investigate the effects of (99)Tc-MDP, a decay product of (99m)Tc-MDP, on the development of choroidal neovascularization (CNV), together with its underlying mechanisms. C57BL/6J mice were used to induce CNV by laser photocoagulation. (99)Tc-MDP at the doses of 0.5 × 10(-1), 1 × 10(-1), and 2 × 10(-1) μg/kg or the same volume of PBS was intraperitoneally injected daily after photocoagulation until the end of the experiment. Seven days after laser injury, mice were perfused with fluorescein-labeled dextran, and areas of CNV were measured. Numbers of infiltrating macrophages, protein levels of VEGF, and inflammation-related molecules including intercellular adhesion molecule (ICAM)-1, tumor necrosis factor (TNF)-α, and matrix metalloproteinases (MMPs) in the RPE-choroid complex were detected 3 days after laser photocoagulation. Effects of (99)Tc-MDP on VEGF-induced endothelial cell migration and tube formation were also studied. Toxicity of (99)Tc-MDP was evaluated in vivo and in vitro. Areas of CNV were significantly suppressed by (99)Tc-MDP treatment without toxicity to the retina compared with PBS treatment in a dose-dependent manner: (99)Tc-MDP treatment of 0.5 × 10(-1) μg/kg (5698.60 ± 1037.70 μm(2)), 1 × 10(-1) μg/kg (3678.34 ± 1328.18 μm(2)), and 2 × 10(-1) μg/kg (2365.78 ± 923.80 μm(2)) suppressed the development of CNV by 36.12%, 58.76%, and 73.48%, respectively, compared with that in the PBS treatment group (8920.36 ± 1097.29 μm(2); P < 0.001). (99)Tc-MDP treatment led to significant inhibition of macrophages infiltrating to CNV together with downregulated protein expressions of VEGF, ICAM-1, TNF-α, and MMP-2. (99)Tc-MDP also showed an inhibitive effect on cell proliferation and VEGF-induced migration and capillary-like tube formation of endothelial cells. Anti-inflammatory treatment with (99)Tc-MDP has therapeutic potential for CNV-related diseases.

Religion is an important determinant in Hispanic Americans (HA) becoming organ donors as HA often believe religion forbids donation. We investigated the effect of an educational program targeting HA organ donation in places of worship. A prospective observational study was conducted at four Catholic churches with a high percentage of HA. A 45 minute ‘culturally sensitive’ educational program, conducted in Spanish, was implemented. Organ donation awareness, knowledge, perception and beliefs, as well as the intent to become an organ donor, were measured before and after the intervention. Differences between before and after the intervention were analyzed. A total of 182 surveys were collected before and 159 surveys were collected after the educational program. A significant increase was observed in organ donation knowledge (54% vs. 70%, p<0.0001), perception (43% vs. 58%, p<0.0001) and beliefs (50% vs. 60%, p=0.0001). However, no significant difference was found in the willingness to discuss donation with family, intent-to-donate, or registering to donate after the intervention. This study demonstrates that a focused educational program in places of worship can significantly improve HA knowledge, perceptions, and beliefs regarding organ donation. Further work is needed to understand why intent-to-donate does not increase despite the increase in organ donation awareness. PMID:23106648

As the proportion of adult orthodontic treatment increases, mainly for aesthetic reasons, orthodontic brackets are directly attached to yttria-stabilized tetragonal zirconia polycrystal (Y-TZP) restorations. This, study analyzed the shear bond strength (SBS) between various surface treated Y-TZP and orthodontic metal brackets. The Y-TZP specimens were conditioned by 110 μm Al2O3 sandblasting, or sandblasting followed by coating with one of the primers (silane, MDP, or an MDP-containing silane primer). After surface treatment, the orthodontic metal bracket was bonded to the specimen using a resin cement, and then 24 h storage in water and thermal cycling (5000 cycles, 5–55 °C), SBS was measured. Surface roughness was analyzed for surface morphology, and X-ray photoelectron spectroscopy (XPS) was employed for characterization of the chemical bond between the Y-TZP and the MDP-based primers (MDP, MDP containing silane primer). It was found that after surface treatment, the surface roughness of all groups increased. The groups treated with 110 μm Al2O3 sandblasting and MDP, or MDP-containing silane primer showed the highest SBS values, at 11.92 ± 1.51 MPa and 13.36 ± 2.31 MPa, respectively. The SBS values significantly decreased in all the groups after thermal cycling. Results from XPS analysis demonstrated the presence of chemical bonds between Y-TZP and MDP. Thus, the application of MDP-based primers after Al2O3 sandblasting enhances the resin bond strength between Y-TZP and the orthodontic metal bracket. However, bonding durability of all the surface-treated groups decreased after thermal cycling. PMID:28772508

This paper presents work being done at NASA/GSFC by the Operating Missions as Nodes on the Internet (OMNI) project to demonstrate the application of the Multicast Dissemination Protocol (MDP) to space missions to reliably transfer files. This work builds on previous work by the OMNI project to apply Internet communication technologies to space communication. The goal of this effort is to provide an inexpensive, reliable, standard, and interoperable mechanism for transferring files in the space communication environment. Limited bandwidth, noise, delay, intermittent connectivity, link asymmetry, and one-way links are all possible issues for space missions. Although these are link-layer issues, they can have a profound effect on the performance of transport and application level protocols. MDP, a UDP-based reliable file transfer protocol, was designed for multicast environments which have to address these same issues, and it has done so successfully. Developed by the Naval Research Lab in the mid 1990's, MDP is now in daily use by both the US Post Office and the DoD. This paper describes the use of MDP to provide automated end-to-end data flow for space missions. It examines the results of a parametric study of MDP in a simulated space link environment and discusses the results in terms of their implications for space missions. Lessons learned are addressed, which suggest minor enhancements to the MDP user interface to add specific features for space mission requirements, such as dynamic control of data rate, and a checkpoint/resume capability. These are features that are provided for in the protocol, but are not implemented in the sample MDP application that was provided. A brief look is also taken at the status of standardization. A version of MDP known as NORM (Neck Oriented Reliable Multicast) is in the process of becoming an IETF standard.

Technetium-99 conjugated with methylene diphosphonate ((99)Tc-MDP) is a novel bisphosphonate derivative without radioactivity and has been successfully used to treat arthritis in China for years. Since bisphosphonate therapy has the potential to induce bisphosphonate-related osteonecrosis of the jaw (BRONJ), we examined whether (99)Tc-MDP represents a new class of bisphosphonate for antiresorptive therapy to ameliorate estrogen deficiency-induced bone resorption with less risk of causing BRONJ. We showed that (99)Tc-MDP-treated, ovariectomized (OVX) mice had significantly improved bone mineral density and trabecular bone volume in comparison to the untreated OVX group by inhibiting osteoclasts and enhancing osteogenic differentiation of bone marrow mesenchymal stem cells. To determine the potential of inducing BRONJ, (99)Tc-MDP/dexamethasone (Dex) or zoledronate/Dex was administered into C57BL/6J mice via the tail vein, followed by extraction of maxillary first molars. Interestingly, (99)Tc-MDP treatment showed less risk to induce osteonecrosis in the maxillary bones compared to zoledronate treatment group, partially because (99)Tc-MDP neither suppressed adaptive regulatory T cells nor activated the inflammatory T-helper-producing interleukin-17 cells. Taken together, our findings demonstrate that (99)Tc-MDP therapy may be a promising approach in the treatment of osteoporosis with less risk of causing BRONJ.

Public surveys conducted in many countries report widespread willingness of individuals to donate a kidney while alive to a family member or close friend, yet thousands suffer and many die each year while waiting for a kidney transplant. Advocates of financial incentive programs or "regulated markets" in kidneys present the problem of the kidney shortage as one of insufficient public motivation to donate, arguing that incentives will increase the number of donors. Others believe the solutions lie-at least in part-in facilitating so-called "altruistic donation;" harnessing the willingness of relatives and friends to donate by addressing the many barriers which serve as disincentives to living donation. Strategies designed to minimize financial barriers to donation and the use of paired kidney exchange programs are increasingly enabling donation, and now, an innovative program designed to address what has been termed "chronologically incompatible donation" is being piloted at the University of California, Los Angeles, and elsewhere in the United States. In this program, a person whose kidney is not currently required for transplantation in a specific recipient may instead donate to the paired exchange program; in return, a commitment is made to the specified recipient that priority access for a living-donor transplant in a paired exchange program will be offered when or if the need arises in the future. We address here potential ethical concerns related to this form of organ "banking" from living donors, and argue that it offers significant benefits without undermining the well-established ethical principles and values currently underpinning living donation programs. © The Author 2017.

Closed reduction (CR) and spica casting is performed using arthrography to assess the adequacy of reduction based in part on the width of medial dye pool (MDP); however, the amount of MDP that is acceptable and its correlation to the actual anatomic position of the femoral head within the acetabulum has been poorly delineated. The purpose of this study was to determine this correlation and to explore the potential limits of acceptable MDP measurements. We retrospectively reviewed a consecutive series of patients with DDH treated at our institution by CR and immediate postoperative magnetic resonance imaging (MRI) and found 20 patients (23 hips) meeting inclusion criteria. We measured the MDP and femoral head area on the best reduced arthrographic image, the immediate postoperative mid-coronal MRI, and on 3 planes (neutral, 30-degree anterior, and 30-degree posterior) of the mid-axial MRI and compared MDP values from both imaging modalities using the Pearson correlation coefficient (R). To provide useful data for establishing intraoperative thresholds, MDP was also expressed as a percentage of femoral head width to control for fluoroscopic magnification. Twenty-two of the 23 hips were reduced on postoperative MRI; the one persistently dislocated hip was excluded from our analysis. The Pearson correlation coefficient was R = 0.73 comparing arthrography and coronal MRI, indicating excellent correlation. Correlation was even stronger between arthrography and axial MRI (neutral R = 0.73; 30-degree anterior, R = 0.81; 30-degree posterior, R = 0.81). The mean fluoroscopic MDP in the successful, fully concentric, CRs was 4.2% of the femoral head width (range, 0.6% to 15.8%). There is very strong correlation between MDP measurements on arthrography and immediate postoperative MRI in both the axial and coronal planes. On the basis of our data, an arthrographic MDP between 0.6% and 15.8% of the femoral head width always resulted in an excellent reduction, suggesting that an MDP of ≤ 16% of femoral head width may be a useful intraoperative criterion for determining the adequacy of CR. Level I Diagnostic Study.

Structural shortage of deceased donor kidneys for transplantation has resulted in the expansion of living donation programs. A number of possibilities are now being explored, since it became clear that donors do not need to be genetically related to their recipients. Apart from classical direct donation we now conduct paired exchange, list exchange, altruistic donation and domino paired exchange programs. Other alternative programs are desensitization and transplantation across the blood type barrier. The purpose of this article is to give a general view of all optimizing living donation programs by reviewing the literature. First we describe logistic solutions, thereafter the more intensive medical treatments. We observed a wide variation in clinical experiences with living donation dependent on local jurisdiction, culture and customs. Professionals disagree on various ethical issues inherent to alternative programs. In our opinion logistic solutions like paired exchange, list exchange and altruistic donation programs are to be preferred over the more medical demanding programs e.g. desensitization and transplantation across the blood type barrier.

For IC design starts below the 20nm technology node, the assist features on photomasks shrink well below 60nm and the printed patterns of those features on masks written by VSB eBeam writers start to show a large deviation from the mask designs. Traditional geometry-based fracturing starts to show large errors for those small features. As a result, other mask data preparation (MDP) methods have become available and adopted, such as rule-based Mask Process Correction (MPC), model-based MPC and eventually model-based MDP. The new MDP methods may place shot edges slightly differently from target to compensate for mask process effects, so that the final patterns on a mask are much closer to the design (which can be viewed as the ideal mask), especially for those assist features. Such an alteration generally produces better masks that are closer to the intended mask design. Traditional XOR-based MDP verification cannot detect problems caused by eBeam effects. Much like model-based OPC verification which became a necessity for OPC a decade ago, we see the same trend in MDP today. Simulation-based MDP verification solution requires a GPU-accelerated computational geometry engine with simulation capabilities. To have a meaningful simulation-based mask check, a good mask process model is needed. The TrueModel® system is a field tested physical mask model developed by D2S. The GPU-accelerated D2S Computational Design Platform (CDP) is used to run simulation-based mask check, as well as model-based MDP. In addition to simulation-based checks such as mask EPE or dose margin, geometry-based rules are also available to detect quality issues such as slivers or CD splits. Dose margin related hotspots can also be detected by setting a correct detection threshold. In this paper, we will demonstrate GPU-acceleration for geometry processing, and give examples of mask check results and performance data. GPU-acceleration is necessary to make simulation-based mask MDP verification acceptable.

The aim of this work was to assess ten-year trends (1999-2010) of adherence to the Mediterranean dietary pattern (MDP) among the Balearic Islands' adult population. Two independent cross-sectional dietary surveys (1999-2000, n = 1200 and 2009-2010 n = 1388, including participants aged 16-65 years) were carried out in the Balearic Islands, Spain. Dietary habits were assessed by means of two 24 h diet recalls and a validated semi-quantitative food-frequency questionnaire that covers 145 food items. Adherence to the MDP was defined according to a score constructed considering the consumption of nine MDP characteristic components: high monounsaturated fatty acids:saturated fatty acids (MUFA:SFA) ratio, moderate ethanol consumption, high legumes, cereals and roots, fruits, vegetables, and fish consumption, and low consumption of meat and milk. Socio-economic status, education level, lifestyle factors and health status were also assessed. Adherence to the MDP was 43.1% (SD 5.8) in 1999-2000 and 44.6% (SD 8.3) in 2009-2010. Higher age was directly associated with higher adherence to the MDP, and this association was stronger in males than in females. Young generations and smokers showed the lowest adherence to MDP, whereas people with higher educational and socio-economic level, and who were physically active showed the highest adherence. According to the place of birth, the increase in the percentage of the adherence to the MDP was observed to be smaller among the Balearic Island's natives than among people born abroad. In 2009-2010, individuals in the MDP's fourth quartile were more likely to be older (aged 46-65 years), and were less likely to have a low occupational level, to have a light physical activity level and to be smoker than in 1999-2000. The adherence to the MDP has been stabilized and slightly recovered among the Balearic Islands' adult population in the last decade.

Special types of kidney transplant exist for patients who have willing but incompatible donors. Two types of transplants that circumvent donor-recipient incompatibility are "kidney paired donation" and "desensitization." Lack of access to these protocols limits living donations and shortens the life span of patients with willing but incompatible donors. To understand potential barriers to implementing kidney paired donation and desensitization, as well as attitudes toward nondirected donation and compatible type O donation, which would maximize the number of kidney paired donation transplants performed via chains. We created a 56-question Web-based survey to elicit information from US transplant program directors about 24 potential barriers to implementing these protocols. Of 166 programs contacted, 96 responded, including 88 complete and 8 partial responses. After pediatric-only programs and multiple responses from the same program were removed, 84 total (78 complete) remained. Respondents were asked to designate each barrier as "major," "minor," or "not a barrier". Availability of dedicated nurse coordinators and the United Network for Organ Sharing's variance request process (although kidney paired donation does not actually require a variance) were significant barriers to kidney paired donation. Most respondents (54%, 42/78) would prefer to participate in a regional rather than a national protocol for kidney paired donation. Risk of complications was the most significant barrier to desensitization. University affiliation, region, and training (nephrologist vs surgeon) had little effect on perception of barriers. Most (92%, 71/78) would evaluate nondirected donations; 53% (41/78) would encourage compatible type O donors to enter kidney paired donation.

One third of healthy willing living kidney donors are rejected due to ABO blood group incompatibility and donor specific antibody. This increases pre-transplant dialysis duration leading to increased morbidity and mortality on the kidney transplantation waiting list. Over the last decade kidney paired donation is most rapidly increased source of living kidney donors. In a kidney transplantation program dominated by living donor kidney transplantation, kidney paired donation is a legal and valid alternative strategy to increase living donor kidney transplantation. This is more useful in countries with limited resources where ABO incompatible kidney transplantation or desensitization protocol is not feasible because of costs/infectious complications and deceased donor kidney transplantation is in initial stages. The matching allocation, ABO blood type imbalance, reciprocity, simultaneity, geography were the limitation for the expansion of kidney paired donation. Here we describe different successful ways to increase living donor kidney transplantation through kidney paired donation. Compatible pairs, domino chain, combination of kidney paired donation with desensitization or ABO incompatible transplantation, international kidney paired donation, non-simultaneous, extended, altruistic donor chain and list exchange are different ways to expand the donor pool. In absence of national kidney paired donation program, a dedicated kidney paired donation team will increase access to living donor kidney transplantation in individual centres with team work. Use of social networking sites to expand donor pool, HLA based national kidney paired donation program will increase quality and quantity of kidney paired donation transplantation. Transplant centres should remove the barriers to a broader implementation of multicentre, national kidney paired donation program to further optimize potential of kidney paired donation to increase transplantation of O group and sensitized patients. This review assists in the development of similar programs in other developing countries. PMID:28507916

We report a study of the renal and whole-blood kinetics of (18)F-fluoride and (99m)Tc-methylene diphosphonate ((99m)Tc-MDP) and their effect on the evaluation of the skeletal kinetics of the two bone tracers. Data were obtained during an investigation of postmenopausal women taking hormone replacement therapy who were compared with untreated, age-matched controls. After intravenous injection of 18F-fluoride (1 MBq), (99m)Tc-MDP (1 MBq), (51)Cr-ethylenediaminetetraacetic acid (51Cr-EDTA) (3 MBq) and (125)I-human serum albumin ((125)I-HSA) (0.25 MBq), multiple blood samples and urine collections were taken between 0 and 4 h after injection. (51)Cr-EDTA data were used to evaluate the glomerular filtration rate (GFR) and the completeness of each timed urine collection. (125)I-HSA data were used to evaluate the plasma volume and the red cell uptake of the other three tracers. At 4 h, the cumulative urine excretions (and standard deviations, SDs) were: (99m)Tc-MDP, 58.2% (4.8%); (18)F-fluoride, 36.1% (5.7%); (51)Cr-EDTA, 81.5% (4.5%). Plots of the renal clearance of (18)F-fluoride against urine volume showed that urine flow rates greater than 5 ml.min-1 were necessary to ensure a constant renal clearance of (18)F and hence stable conditions for the evaluation of bone tracer kinetics. In contrast, a low urine flow rate had no effect on the renal kinetics of (99m)Tc-MDP. For MDP, the evaluation of skeletal kinetics requires data on protein binding so that calculations can be performed for free MDP. In the present study, protein binding of MDP was evaluated from the ratio of total (99m)Tc-MDP renal clearance to GFR based on the principle that free (99m)Tc-MDP is a GFR tracer. Between 0 and 4 h after injection, the fractional protein binding of MDP increased linearly with time, changing from 21+/-5% immediately after injection to 58+/-5% at 4 h. Although red cell uptake of (99m)Tc-MDP was negligible, for (18)F-fluoride around 30% of circulating tracer was transported in red cells. In view of the data showing the rapid transport of (18)F-fluoride across the red cell membrane, bone kinetic data for (18)F are more accurately reported as whole-blood clearance rather than plasma clearance.

Examination of major duodenal papilla (MDP) by standard forward-viewing esophagogastroduodenoscopy (S-EGD) is limited. Cap assisted esophagogastroduodenoscopy (CA-EGD) utilizes a cap fitted to the tip of the endoscope that can depress the mucosal folds and thus might improve visualization of MDP. The aim of this study was to compare CA-EGD to S-EGD for complete examination of the MDP. Prospective, randomized, blinded, controlled crossover study. Subjects scheduled for elective EGD were randomized to undergo S-EGD (group A) or CA-EGD (group B) before undergoing a second examination by the alternate method. Images of the MDP were evaluated by three blinded multicenter-experts. Our primary outcome measure was complete examination of the papilla. Secondary outcome measures were duration and overall diagnostic yield. A total of 101 patients were randomized and completed the study. Complete examination of MDP was achieved in 98 patients using CA-EGD compared to 24 patients using S-EGD (97 vs. 24%, P<0.001). Median duration from intubation of the esophagus until localization of the MDP was shorter with CA-EGD (46. vs. 96 s., P<0.001). In group A, 11 extra lesions and 12 additional incidental findings were detected by secondary CA-EGD, whereas neither were detected by secondary S-EGD in group B (22 vs. 0% and 24 vs. 0%, P<0.001 and P<0.001). CA-EGD enabled complete examination of MDP in almost all cases compared to a low success rate of S-EGD. CA-EGD detected a significant amount of lesions and incidental findings when added to S-EGD. CA-EGD is a safe and effective method for examination of MDP.

This study investigates antecedents and outcomes of entertainment television consumption in organ donation with the Orientation₁-Stimulus-Orientation₂-Response (O₁-S-O₂ -R) model. It reveals that organ donation knowledge seems significantly related to recall of entertainment television programs and attitudes toward organ donation. Meanwhile, recall of entertainment television programs significantly predicts people's perception of medical mistrust, which in turn negatively predicts attitudes toward organ donation, while attitudes toward organ donation significantly predict behavioral intention in signing a donor card. It also suggests significant mediation relationships among the pre-orientation variable, stimulus, post-orientation variable, and attitudinal and behavioral outcomes. This study provides an integrative theoretical framework to study media effects on organ donation and empirical evidence for "entertainment miseducation" (Morgan, Harrison, Chewning, Davis, & DiCorcia, 2007).
Modular Toolkit for Data Processing (MDP): A Python Data Processing Framework.
Zito, Tiziano; Wilbert, Niko; Wiskott, Laurenz; Berkes, Pietro
2008-01-01
Modular toolkit for Data Processing (MDP) is a data processing framework written in Python. From the user's perspective, MDP is a collection of supervised and unsupervised learning algorithms and other data processing units that can be combined into data processing sequences and more complex feed-forward network architectures. Computations are performed efficiently in terms of speed and memory requirements. From the scientific developer's perspective, MDP is a modular framework, which can easily be expanded. The implementation of new algorithms is easy and intuitive. The new implemented units are then automatically integrated with the rest of the library. MDP has been written in the context of theoretical research in neuroscience, but it has been designed to be helpful in any context where trainable data processing algorithms are used. Its simplicity on the user's side, the variety of readily available algorithms, and the reusability of the implemented units make it also a useful educational tool.
Inhibition of endogenous pyrogen-induced fever by a muramyl dipeptide derivative.
Parant, M; Riveau, G; Parant, F; Chedid, L

N-acetylmuramyl-L-alanyl-D-isoglutamine, or muramyl dipeptide (MDP), is a synthetic immunoadjuvant analogue of a bacterial peptidoglycan subunit that has a definite pyrogenic effect in the rabbit. Some adjuvant-active derivatives such as murabutide [MDP(Gln)-OnBu] or murametide [MDP(Gln)-OMe] are not pyrogenic. Murabutide did not stimulate human or rabbit cells to release endogenous pyrogen (EP), but murametide induced EP production at the same dosage levels as MDP. Moreover, plasma from rabbits treated with murametide transferred into untreated recipients elicited a febrile response typical of EP fever and comparable with that induced by plasma from MDP-treated animals. Murametide not only inhibited the central effect of EP that is generated but also the effect of an extra dose of EP administered later by the intravenous route. Moreover, pretreatment of rabbits with murametide decreased fever responses induced by certain high-molecular-weight exogenous pyrogens as mediated through the production of EP.

Creating reliable and durable adhesion to the nonactive zirconia surface is difficult and has limited zirconia use. The introduction of functional monomers such as 10-methacryloyloxydecyl dihydrogen phosphate (MDP) appears to have enhanced bond strength to zirconia. The purpose of this in vitro study was to evaluate the long-term bond strength of several MDP-containing primer/cement systems to zirconia. Zirconia blocks were divided into 6 groups (n=24) according to the 3 primers/cements to be bonded, as follows: Scotchbond Universal/RelyX Ultimate (SU/RU; consisting of MDP-containing primer/MDP-free cement); Clearfil ceramic primer/Panavia F (CCP/PAN; consisting ofMDP-containing/MDP-containing); and Z-Prime Plus/Duo-Link (ZP/DUO; consisting ofMDP-containing/MDP-free), which were compared with 3 nonprimed groups, RU, PAN, and DUO. After bonding, each group was further divided into 3 subgroups (n=8) according to the level of aging: 24-hour storage in water at 37°C (24H); 30-day storage at 37°C (30D); and 30-day storage at 37°C followed by 3000 thermal cycles (30D/TC). After aging, a shear bond strength test and failure mode analysis were performed. The data were analyzed using 2-way ANOVA (α=.05). After aging, nearly all primer/cement groups presented significantly higher bond strength than the related nonprimed groups for each level of aging (P<.05), except for CCP/PAN versus PAN with 24H (P=.741). SU/RU had the highest bond strength among the groups for all treatments (P<.05), except for CCP/PAN versus SU/RU with 30D/TC (P=.171). Among the nonprimed groups, only RU went through 30D/TC without premature debonding. With 24H and 30D, the failure modes in SU/RU and CCP/PAN were purely mixed, whereas those in the other groups were mainly adhesive, except for RU. The superiority of the initial bond strength in SU/RU may result from some functional components other than MDP. The presence of MDP in the cement did not appear to have a positive effect on long-term bond strength to zirconia. Copyright © 2016 Editorial Council for the Journal of Prosthetic Dentistry.

Vascular endothelium dysfunction caused by oxidative stress accelerates the pathologic process of cardiovascular diseases. NOD2, an essential receptor of innate immune system, has been demonstrated to play a critical role in atherosclerosis. Here, the aim of our study was to investigate the effect and underlying molecular mechanism of muramyl dipeptide (MDP) on NOX4-mediated ROS generation in human umbilical vein endothelial cells (HUVECs). 2,7-dichlorofluorescein diacetate staining was to measure the intracellular ROS level and showed MDP promoted ROS production in a time- and dose-dependent manner. The mRNA and protein levels of NOX4 and COX-2 were detected by real-time PCR and western blot. Small interfering RNA (siRNA) was used to silence NOD2 or COX-2 gene expression and investigate the mechanism of NOD2-mediated signaling pathway in HUVECs. Data showed that MDP induced NOX4 and COX-2 expression in a time- and dose-dependent manner. NOD2 knock-down suppressed up-regulation of COX-2 and NOX4 in HUVECs treated with MDP. Furthermore, silence of COX-2 in HUVECs down-regulated the NOX4 expression after MDP stimulation. Collectively, we indicated that NOD2 played a leading role in MDP-induced COX-2/NOX4/ROS signaling pathway in HUVECs, which was a novel regulatory mechanism in the progress of ROS generation.

The California State University (CSU) Chancellor's Office reached an agreement with all CSU collective bargaining units and Employee Relations on a uniform Catastrophic (CAT) Leave Donation Program in 1992. The CAT Leave Donation Program allows employees to donate sick and/or vacation leave credits to employees who are incapacitated due to a catastrophic illness or injury and have exhausted all of their own leave credits. This also extends to employees with whom family illnesses are deemed catastrophic, thus requiring the employee to care for an immediate family member. Stakeholders include union represented employees who accrue leave credits as well as any employee who receives or donates hours of leave credits in the program. Other stakeholders include the family members and program administrators.

Entrepreneurial ventures and whole-body donations: a regional perspective from the United States.
Anteby, Michel; Hyman, Mikell
2008-02-01
Human cadavers are crucial to medical science. While the debate on how to secure sufficient cadavers has focused primarily on donors' behaviors, procuring organizations' roles in increasing donations remain less explored. The United States offers a unique setting in which to examine this question since entrepreneurial ventures supplying cadavers for medical science have recently emerged alongside traditional academic-housed programs, raising both hopes and fears about their impact on whole-body donations. To assess their potential impact, an archival survey of voluntary, in-state whole-body donors to two programs procuring in the same U.S. state was conducted. The programs' specimen recipients were also analyzed. One program is academic-housed and the other is an entrepreneurial venture. Both offered equal levels of financial support to donating parties. Eighty donations and 120 specimen shipping invoices from 2005 were analyzed in each program. Donations to the two programs did not significantly differ in terms of donors' sex, marital status, maximum educational level, and estimated hourly wage. The entrepreneurial venture's donors were, however, significantly younger, more likely to be from a minority group, and more likely to have died from cancer. For-profit organizations, continuing medical training organizations, and medical device companies were more likely recipients of the entrepreneurial venture's specimens. Non-profit and academic organizations were more likely recipients of the academic-housed program's specimens. These findings suggest that although the programs procured from a somewhat similar pool of donors, they also complemented one another. The entrepreneurial program procured donations that the academic-housed program often did not attract. Specimen recipients' distinct demands partly explain these procurement behaviors. Thus, organizational efforts to meet demands seem to shape the supply. Examining organizations alongside donors might provide new answers to secure donations.
Body donations today and tomorrow: What is best practice and why?
Riederer, Beat M
2016-01-01
There is considerable agreement that the use of human bodies for teaching and research remains important, yet not all universities use dissection to teach human gross anatomy. The concept of body donation has evolved over centuries and there are still considerable discrepancies among countries regarding the means by which human bodies are acquired and used for education and research. Many countries have well-established donation programs and use body dissection to teach most if not all human gross anatomy. In contrast, there are countries without donation programs that use unclaimed bodies or perhaps a few donated bodies instead. In several countries, use of cadavers for dissection is unthinkable for cultural or religious reasons. Against this background, successful donation programs are highlighted in the present review, emphasizing those aspects of the programs that make them successful. Looking to the future, we consider what best practice could look like and how the use of unclaimed bodies for anatomy teaching could be replaced. From an ethical point of view, countries that depend upon unclaimed bodies of dubious provenance are encouraged to use these reports and adopt strategies for developing successful donation programs. In many countries, the act of body donation has been guided by laws and ethical frameworks and has evolved alongside the needs for medical knowledge and for improved teaching of human anatomy. There will also be a future need for human bodies to ensure optimal pre- and post-graduate training and for use in biomedical research. Good body donation practice should be adopted wherever possible, moving away from the use of unclaimed bodies of dubious provenance and adopting strategies to favor the establishment of successful donation programs. © 2015 Wiley Periodicals, Inc.

The present study was conducted to examine the effect of a lipophilic analog of muramyl dipeptide, 6-O-stearoyl-N-acetylmuramyl-L-alpha-aminobutyryl-D-isoglutamine (6-O-S-Abu-MDP), a macrophage activator, on the prophylactic activity of liposomal amphotericin B (L-AmpB) against disseminated candidiasis in mice. Multilamellar vesicles containing AmpB and (6-O-S-Abu)-MDP were prepared by using dimyristoyl phosphatidylcholine and dimyristoyl phosphatidylglycerol (7:3 molar ratio). Hale-Stoner mice (6 to 8 weeks old) were injected with 7 X 10(5) CFU of Candida albicans 336 isolated from a patient. Groups of mice were injected intravenously with different doses of L-AmpB and L-(6-O-S-Abu)-MDP, individually or in combination, 2 days before challenge with C. albicans. The mice were injected with a fixed dose of L-AmpB (1.2 mg/kg in 400 mg of lipid per kg) and various doses of L-(6-O-S-Abu)-MDP (0.6, 1.2, 2, and 4 mg/kg in 400 mg of lipid per kg) or vice versa. Other control groups included untreated mice and those receiving empty liposomes (400 mg of lipid per kg), free AmpB (0.6 mg/kg), or free (6-O-S-Abu)-MDP (4 mg/kg). The mice receiving L-AmpB (1.2 mg/kg) plus L-(6-O-S-Abu)-MDP (0.6 to 4.0 mg/kg) survived up to 25 to 30 days as compared with those injected with L-AmpB alone (15 days) or with L-(6-O-S-Abu)-MDP alone (10 to 15 days). All the mice in other control groups died within 7 to 11 days. The kidney cultures of the mice that received L-AmpB (4 mg/kg) plus L-(6-O-S-Abu)-MDP (1.2 mg/kg) were free of C. albicans infection, unlike those injected with L-AmpB. Variance analysis of these findings indicates a synergistic activity between L-AmpB and L-(6-O-S-Abu)-MDP in the prophylaxis of candidiasis. PMID:4073873

As the number of donated organs is still extremely small in Japan compared with other developed countries, in-hospital procurement transplant coordinators (In-Hp PTC) may play an important role in increasing organ donation and making the procurement procedure smoother. In this study, our education program of In-Hp PTC is described. In May 2012, our department started the In-Hp PTC Education Program. In the first semester, a 2-hour lecture is provided every 2 weeks for 5 months to 15 In-Hp PTCs working near Osaka. In the second semester, 20 lectures were provided for 3 consecutive days to 31 In Hp PTCs, more than 80% of whom work far from Osaka. Lecture topics were the history and current status of organ donation in Japan, social regulation of organ donation, care of transplant recipients, overall procedures of organ donation, the role of In-Hp PTC, donor family care, donor indications, and donor assessment and management. Lectures also included simulations of the organ donation process. Participants were surveyed for their opinions after the program, Most participants were satisfied with the program, topics and duration. As most of them are not full-time In-Hp PTCs, they preferred to attend the 3-day program. Many participants are currently working as main In-Hp PTCs and establishing their own organ donation system in their hospital. In-Hp PTCs have an important role to play in establishing an organ procurement system and increasing organ donation in Japan. This program may help establish a systematic education program for this occupation in Japan. Copyright © 2014 Elsevier Inc. All rights reserved.

The aim of this study was to investigate the safety and efficacy of intravitreal injection of (99)Tc-MDP, a decay product of (99m)Tc-MDP, on the development of laser-induced choroidal neovascularization (CNV) in rhesus monkeys. Experimental CNV was induced by argon laser with a small high-energy laser spot. Monkeys were given 50 μL of (99)Tc-MDP at a concentration of 0.005 μg/mL (n = 6) or 0.01 μg/mL (n = 6) by intravitreal injection once a week immediately after laser injury for a period of 56 days. Control animals were treated with the same volume of PBS (n = 6) in the same way. Eyes were monitored by ophthalmic examination, color fundus photography, fluorescence fundus angiography (FFA), optical coherence tomography (OCT) and histology. Incidences of grade 4 CNV lesions as well as the leakage areas of grade 4 CNVs on the late-phase of fluorescein angiograms were measured in a standardized, randomized and masked fashion fortnightly. The maximum widths and heights of grade 4 CNVs were also calculated by histology at the end of the experiment. Toxicity of (99)Tc-MDP on the retina was evaluated by electroretinogram (ERG) and histologic analysis. (99)Tc-MDP reduced the incidences of grade 4 CNVs by 33.33 % and 39.40 % in the 0.005 μg/mL and 0.01 μg/mL groups, respectively, compared with the PBS group on day 28 (P < 0.05; n = 6). The leakage areas of grade 4 CNVs were smaller in the 0.005 μg/mL (0.7136 ± 0.0283 mm(2), p <0.01; n = 6) and 0.01 μg/mL (0.4351 ± 0.0349 mm(2), p < 0.01; n = 6) groups than those in the PBS control group (0.9373 ± 0.0455 mm(2); n = 6) in a dose-dependent manner on day 28. OCT and histology also showed that the sizes of CNVs were smaller in the (99)Tc-MDP treated groups than those in the PBS group. Although intravitreal injection of (99)Tc-MDP led to mild inflammatory reaction in the anterior chamber, histology and ERG findings demonstrated that (99)Tc-MDP did not cause any change in histological structure or function of the retina (p>0.05). Intravitreal injection of (99)Tc-MDP can inhibit the development of laser-induced CNV without toxic effect on retina, suggesting that (99)Tc-MDP has therapeutic potential for CNV related diseases.

Wine quality study was carried out with 24 vintages of Cabernet-Sauvignon (CS) and 7 vintages of Merlot (M) produced by two different Bordeaux wine-growing areas. Proanthocyanidin monomers and oligomers were identified and quantified by HPLC-UV-Fluo. Percentage of galloylation (%G), of prodelphinidins (%P) as well as mean degree of polymerisation (mDP) were also determined. Total phenolic compounds, total anthocyanins, total tannins, hue, CI (colour intensity), titratable acidity, ethanol level and pH were evaluated. Sensory analysis concerning astringency and bitterness intensity was also performed. Total phenolic compounds, total anthocyanins, total tannins, tannin monomers, hue, CI, % G, % P, mDP and astringency intensity differentiate both wines (M and CS) according to vintage. Correlations between wine age and: mDP, hue, astringency and tannin monomers (C+EC) are obtained. Qualitative tannin characterisation is established by correlation between astringency and mDP (R(2)=0.509, p=0.051, CS; R(2)=0.780, p=0.000M). In addition, mDP decreases significantly during ageing (R(2)=0.796, p=0.000; CS and R(2)=0.946, p=0.000; M). Scale patterns between wine mDP and tannin perception (astringency) are proposed.

The present study aimed to determine the effect of the functional monomer, 10-methacryloxydecyl dihydrogen phosphate (MDP), on the enamel bond durability of single-step self-etch adhesives through integrating fatigue testing and long-term water storage. An MDP-containing self-etch adhesive, Clearfil Bond SE ONE (SE), and an experimental adhesive, MDP-free (MF), which comprised the same ingredients as SE apart from MDP, were used. Shear bond strength (SBS) and shear fatigue strength (SFS) were measured with or without phosphoric acid pre-etching. The specimens were stored in distilled water for 24 h, 6 months, or 1 yr. Although similar SBS and SFS values were obtained for SE with pre-etching and for MF after 24 h of storage in distilled water, SE with pre-etching showed higher SBS and SFS values than MF after storage in water for 6 months or 1 yr. Regardless of the pre-etching procedure, SE showed higher SBS and SFS values after 6 months of storage in distilled water than after 24 h or 1 yr. To conclude, MDP might play an important role in enhancing not only bond strength but also bond durability with respect to repeated subcritical loading after long-term water storage. © 2015 Eur J Oral Sci.

Gene expression in apple roots in response to various stress conditions is a less-explored research subject. Reliable reference genes for normalizing quantitative gene expression data have not been carefully investigated. In this study, the suitability of a set of 15 apple genes were evaluated for their potential use as reliable reference genes. These genes were selected based on their low variance of gene expression in apple root tissues from a recent RNA-seq data set, and a few previously reported apple reference genes for other tissue types. Four methods, Delta Ct, geNorm, NormFinder and BestKeeper, were used to evaluate their stability in apple root tissues of various genotypes and under different experimental conditions. A small panel of stably expressed genes, MDP0000095375, MDP0000147424, MDP0000233640, MDP0000326399 and MDP0000173025 were recommended for normalizing quantitative gene expression data in apple roots under various abiotic or biotic stresses. When the most stable and least stable reference genes were used for data normalization, significant differences were observed on the expression patterns of two target genes, MdLecRLK5 (MDP0000228426, a gene encoding a lectin receptor like kinase) and MdMAPK3 (MDP0000187103, a gene encoding a mitogen-activated protein kinase). Our data also indicated that for those carefully validated reference genes, a single reference gene is sufficient for reliable normalization of the quantitative gene expression. Depending on the experimental conditions, the most suitable reference genes can be specific to the sample of interest for more reliable RT-qPCR data normalization.

Ethical Dilemmas for Oocyte Donations: Slippery Slope for Conflicts of Interest.
Tulay, Pinar
2016-01-01
Oocyte donations have increased with improvements in oocyte cryopreservation procedures in recent years. Women with medical conditions that require chemotherapy or radiotherapy have begun to opt for oocyte cryo¬preservation prior to their treatment or to enroll in an oocyte donation program. Alternatively, some women apply for "third-party" oocyte donation programs for nonmedical reasons such as delayed childbearing. Although society seems to accept oocyte donations for medical reasons, it appears that there are still some moral issues surrounding nonmedical oocyte donations. In this review, the ethical aspects of oocyte donations and donors' perspectives are discussed. With developing technologies, the genetic screening of donors has expanded to include diseases. This review explores the ethical issues involved in genetic screening of gamete donors.

Injection efficiency from evaporated Au contacts on a molecularly doped polymer (MDP) system has been previously observed to evolve from blocking to ohmic over time. In the present article this contact forming phenomenon is analyzed in detail. The initially blocking nature of the Au contact is in contrast with that expected from the relative workfunctions of Au and of the polymer which suggest Au should inject holes efficiently. It is also in apparent contrast to a differently prepared interface of the same materials. The phenomenon is not unique to this interface, having been confirmed also for evaporated Ag and mechanically made liquid Hg contacts on the same MDP. The MDP is a disordered solid state solution of electroactive triarylamine hole transporting TPD molecules in a polycarbonate matrix. The trap-free hole-transport MDP provides a model system for the study of metal/polymer interfaces by enabling the use of a recently developed technique that gives a quantitative measure of contact injection efficiency. The technique combines field-dependent steady state injection current measurements at a contact under test with time-of-flight (TOF) mobility measurements made on the same sample. In the present case, MDP films were prepared with two top vapor-deposited contacts, one of Au (test contact) and one of Al (for TOF), and a bottom carbon-loaded polymer electrode which is known to be ohmic for hole injection. The samples were aged at various temperatures below the glass transition of the MDP (85 °C) and the evolution of current versus field and capacitance versus frequency behaviors are followed in detail over time and analyzed. Control measurements ensure that the evolution of the electrical properties is due to the Au/polymer interface behavior and not the bulk. All evaporated Au contacts eventually achieved ohmic injection. The evaporated Au/MDP interface was also investigated by transmission electron microscopy as a function of time and showed no evidence of Au interdiffusion in the MDP layer, remaining abrupt to within ˜10 Å over the course of the evolution in injection efficiency. Mechanisms related to Au penetration into the MDP are therefore unlikely. Rapid sequence data acquisition enabled the detection of two main processes in the injection evolution. The evolving injection efficiency is very well fit by two exponentials, enabling the characterization of time and temperature dependence of the evolution processes.
The silence of Good Samaritan kidney donation in Australia: a survey of hospital websites.
Bramstedt, Katrina A; Dave, Sameer
2013-01-01
It is common for living donor candidates to use the Internet as a tool to enhance their decision-making process. Specifically, the websites of transplant hospitals can potentially be a vital source of information for those contemplating living donation. In an effort to explore the low incidence of Good Samaritan kidney donation (donations to strangers) in Australia, two raters conducted a nine-attribute website content analysis for all hospitals which participate in these transplants (n = 15). Overall, the concept of living donation is relatively silent on Australian hospital websites. Only four hospitals mention their living donor program, and only one mentions their Good Samaritan program. No site linked directly to Australia's AKX Paired Kidney Exchange Program - the only program which facilitates pair and chain transplants in Australia. Further, information about deceased donation is nearly absent as well. An individual with the altruistic desire to donate will generally find scant or absent information about donation at the website of their local transplant hospital, although this information could easily be present as an educational tool which supports the consent process. Using a hospital website to educate the public about a clinical service should not be viewed as ethically problematic (solicitation), but rather an ethical essential. © 2013 John Wiley & Sons A/S.
Mass media, online social network, and organ donation: old mistakes and new perspectives.
Aykas, A; Uslu, A; Şimşek, C

Contrary to TV programs projecting awareness about organ donation in society, concrete evidence exists about adverse influence of negative broadcasts on organ donation rates. We sought to determine the effect of mass media on public opinion toward organ donation and the efficacy of public campaigns and novel social media attempts on donation rates. We conducted a systematic review of relevant literature and national campaign results. Hoaxes about brain death and organ transplantation adversely affect organ donation rates in both Western and Eastern societies. Scientifically controversial and exaggerated press conferences and institutional advertisements create mistrust in doctors, thus reducing organ donation. The overall effect of public education campaigns in promoting organ donation is a temporary 5% gain. Increments in organ donation rates is expected with novel applications of social media (Facebook effect). Communication, based on mutual trust, must be established between medicine and the media. Continuing education programs with regard to public awareness on organ donation should be conducted over social media. Copyright © 2015 Elsevier Inc. All rights reserved.

The use of dissection to study human anatomy is the foundation for educational excellence among future health professionals, as it offers an ideal opportunity to learn the body's morphology in three dimensions while also providing students with a more humanistic education. The shortage of bodies for dissection, combined with the Brazilian population's lack of knowledge concerning the possibility of voluntarily donating their own bodies, led to the creation of the Body Donation Programs for Education and Research in Anatomy at the Federal University of Health Sciences of Porto Alegre (UFCSPA). The program is based on three pillars: Informing the general public about the program, donor registration, and donation itself. Since the creation of the donor program in 2008, there has been an increase in both the number of donations made during donor's lifetime and the number of bodies received by the university. There has also been a shift in relation to the origin of these bodies, as before the creation of the program most bodies were unclaimed cadavers, while today most of the bodies are sourced from voluntary donations. The initial results regarding the public's acceptance of the possibility of making body donations have been encouraging, as shown by the annual growth in donor registrations. Consequently, the quality and quantity of the material available for educational purposes have greatly improved. Copyright © 2012 American Association of Anatomists.

Background Several methodological issues with non-randomized comparative clinical studies have been raised, one of which is whether the methods used can adequately identify uncertainties that evolve dynamically with time in real-world systems. The objective of this study is to compare the effectiveness of different combinations of Traditional Chinese Medicine (TCM) treatments and combinations of TCM and Western medicine interventions in patients with acute ischemic stroke (AIS) by using Markov decision process (MDP) theory. MDP theory appears to be a promising new method for use in comparative effectiveness research. Methods The electronic health records (EHR) of patients with AIS hospitalized at the 2nd Affiliated Hospital of Guangzhou University of Chinese Medicine between May 2005 and July 2008 were collected. Each record was portioned into two "state-action-reward" stages divided by three time points: the first, third, and last day of hospital stay. We used the well-developed optimality technique in MDP theory with the finite horizon criterion to make the dynamic comparison of different treatment combinations. Results A total of 1504 records with a primary diagnosis of AIS were identified. Only states with more than 10 (including 10) patients' information were included, which gave 960 records to be enrolled in the MDP model. Optimal combinations were obtained for 30 types of patient condition. Conclusion MDP theory makes it possible to dynamically compare the effectiveness of different combinations of treatments. However, the optimal interventions obtained by the MDP theory here require further validation in clinical practice. Further exploratory studies with MDP theory in other areas in which complex interventions are common would be worthwhile. PMID:22400712
A learning-based agent for home neurorehabilitation.

This paper presents the iterative development of an artificially intelligent system to promote home-based neurorehabilitation. Although proper, structured practice of rehabilitation exercises at home is the key to successful recovery of motor functions, there is no home-program out there which can monitor a patient's exercise-related activities and provide corrective feedback in real time. To this end, we designed a Learning from Demonstration (LfD) based home-rehabilitation framework that combines advanced robot learning algorithms with commercially available wearable technologies. The proposed system uses exercise-related motion information and electromyography signals (EMG) of a patient to train a Markov Decision Process (MDP). The trained MDP model can enable an agent to serve as a coach for a patient. On a system level, this is the first initiative, to the best of our knowledge, to employ LfD in an health-care application to enable lay users to program an intelligent system. From a rehabilitation research perspective, this is a completely novel initiative to employ machine learning to provide interactive corrective feedback to a patient in home settings.

Intestinal dysbiosis contributes to obesity and insulin resistance, but intervening with antibiotics, prebiotics, or probiotics can be limited by specificity or sustained changes in microbial composition. Postbiotics include bacterial components such as lipopolysaccharides, which have been shown to promote insulin resistance during metabolic endotoxemia. We found that bacterial cell wall-derived muramyl dipeptide (MDP) is an insulin-sensitizing postbiotic that requires NOD2. Injecting MDP lowered adipose inflammation and reduced glucose intolerance in obese mice without causing weight loss or altering the composition of the microbiome. MDP reduced hepatic insulin resistance during obesity and low-level endotoxemia. NOD1-activating muropeptides worsened glucose tolerance. IRF4 distinguished opposing glycemic responses to different types of peptidoglycan and was required for MDP/NOD2-induced insulin sensitization and lower metabolic tissue inflammation during obesity and endotoxemia. IRF4 was dispensable for exacerbated glucose intolerance via NOD1. Mifamurtide, an MDP-based drug with orphan drug status, was an insulin sensitizer at clinically relevant doses in obese mice.

According to the 'Adhesion-Decalcification' concept, specific functional monomers within dental adhesives can ionically interact with hydroxyapatite (HAp). Such ionic bonding has been demonstrated for 10-methacryloyloxydecyl dihydrogen phosphate (MDP) to manifest in the form of self-assembled 'nano-layering'. However, it remained to be explored if such nano-layering also occurs on tooth tissue when commercial MDP-containing adhesives (Clearfil SE Bond, Kuraray; Scotchbond Universal, 3M ESPE) were applied following common clinical application protocols. We therefore characterized adhesive-dentin interfaces chemically, using x-ray diffraction (XRD) and energy-dispersive x-ray spectroscopy (EDS), and ultrastructurally, using (scanning) transmission electron microscopy (TEM/STEM). Both adhesives revealed nano-layering at the adhesive interface, not only within the hybrid layer but also, particularly for Clearfil SE Bond (Kuraray), extending into the adhesive layer. Since such self-assembled nano-layering of two 10-MDP molecules, joined by stable MDP-Ca salt formation, must make the adhesive interface more resistant to biodegradation, it may well explain the documented favorable clinical longevity of bonds produced by 10-MDP-based adhesives.

Organ donation and transplant systems have unique characteristics based on the local culture and socioeconomic context. China's transplant and organ donation systems developed without regulatory oversight until 2006 when regulation and policy were developed and then implemented over the next several years. Most recently, the pilot project of establishing a voluntary citizen-based deceased donor program was established. The pilot program addressed the legal, financial, and cultural barriers to organ donation in China. The pilot program has evolved into a national program. Significantly, it established a uniquely Chinese donor classification system. The Chinese donor classification system recognizes donation after brain death (category I), donation after circulatory death (category II), and donation after brain death followed by circulatory death (category III). Through August 2014, the system has identified 2326 donors and provided 6416 organs that have been allocated though a transparent organ allocation system. The estimated number of donors in 2014 is 1147. As China's attitudes toward organ donation have matured and evolved and as China, as a nation, is taking its place on the world stage, it is recognizing that its past practice of using organs from executed prisoners is not sustainable. It is time to recognize that the efforts to regulate transplantation and provide voluntary citizen-based deceased organ donation have been successful and that China should use this system to provide organs for all transplants in every province and hospital in China. At the national organ transplant congress on October 30, 2014, the Chairman of the China's national organ donation and transplantation committee, Jeifu Huang required all hospitals to stop using organs from executed prisoners immediately and the civilian organ donation will be sole source for organ transplant in China starting January 2015. © 2015 American Association for the Study of Liver Diseases.

Australian donation leaders recognized that to increase organ donation outcomes, health professionals conducting family donation conversations (FDCs) required support and specialist training. An international training institute with programs based on proven results was engaged to create and implement a customized training program to influence change in FDC practice and culture. The goal was to increase donation rates by developing and implementing a customized, self-sustaining training program to enhance FDC practices of health professionals. Other goals included providing training and communications skills to lead FDC, supporting families in making decisions, and influencing health professionals to adopt FDC practices. To gain support and determine program suitability, two 1-day pilot training sessions were provided to 45 Australian donation leaders in 2011. Training was further customized with an emphasis on creating changes to achieve and sustain desired results. A comprehensive national training plan was implemented over 18 months. Twenty-six 2-day FDC training workshops were held in 8 cities (646 participants). Program evaluations and debriefings showed distinct shifts in perspectives and an enthusiasm to implement new processes. In 2012 to 2013, an instructor program was developed to transition training facilitation. The training institute remains involved in development and training to build and sustain skill and expertise. There was a 58% increase in organ donors in Australia from 2009 to 2013 (data reflect 2013 Australian end-of-year organ donation information). This represents a 36% increase in organ donors (2009-2011); the remaining 22% increase was achieved in the 2 years since the FDC training was implemented in Australia (2011-2013). Improved skills training in the conduct of FDCs seem to have contributed to improved donation outcomes in national identification, request, and consent rates. The integration of another organization's process poses distinct challenges; thoughtful collaboration, sensitive to cultural aspects and family care, communication, and donation practices, can result in successful customized training that shifts perspectives, provides new skills, and achieves and sustains an increase in organ donation rates.

To determine whether Brazilian egg donation treatment outcomes with oocytes donated from infertile couples are equivalent to those obtained worldwide with oocytes donated from fertile egg-donors. In this descriptive study, egg-donation cycles from 259 women, performed from January 2009 to July 2013, were evaluated. Oocytes were obtained from patients undergoing ICSI who decided to donate their surplus oocytes. We described the survival, fertilization, blastocyst, implantation and pregnancy rates obtained in our infertile donor-recipient program. In addition, we described the results obtained in previous published studies. In our egg-donation program we obtained a fertilization rate of 72.9 %, a blastocyst formation rate of 53.2 %, an implantation rate of 31.1 % and the estimated clinical pregnancy rate per warmed oocyte was 5.4 %. The analyzed studies, performed between 2008 and 2013, included varying numbers of egg-donors (range: 20-600), warmed oocytes (range: 123-3826) and survival rates (range: 85.6-92.5 %). Fertilization rates ranged from 74.2 to 87.0 %, blastocyst formation rate ranged from 41.3 % to 68.0 %, implantation rates ranged from 24.7 % to 55.3 % and the clinical pregnancy rate per warmed oocyte ranged from 3.9 % to 9.8 %. New and reassuring information derived from our egg-donation program demonstrates outcomes similar to those reported for other egg donation programs.

From October 1997 to July 2010, only 86 brain-dead (BD) organ donations were obtained and no organs were retrieved from children under 15 years of age because of the strict Japan Organ Transplantation Act. The Act was revised on July 17, 2010, allowing organs to be donated after BD with family consent. To manage the increased donations after the revision, the Japan Organ Transplant Network (JOT) employed 10 organ procurement coordinators (OPCs) and modified its education systems. We retrospectively reviewed the modified education programs to evaluate whether they were effective and whether the processes of organ donation were promptly performed after the revision of the Act. The modifications of education program were: changing OPC to guideline manuals to correspond to the revised Transplant Act; OPCs were taught the new organ procurement system; and a special education program was provided for the 10 newcomers for 2 months. After 12 months of the revision, 58 BD organ donations were accomplished, whereas they had averaged 6.6 in a year before the revision. Two pediatric BD organ donations were accomplished without problem. One priority organ donation to a relative was performed uneventfully. After applying the modified education program, skilled JOT OPCs and leader JOT OPCs increased. To manage increased organ donations after the revision of the Act, the educational system was modified and 58 brain dead organ donations were performed safely. Copyright © 2012 Elsevier Inc.

Voucher-based reinforcement therapy (VBRT) is an effective drug abuse treatment, but the cost of VBRT rewards has limited its dissemination. Obtaining VBRT incentives through donations may be one way to overcome this barrier. Two direct mail campaigns solicited donations for use in VBRT for pregnant, postpartum, and parenting drug users in Toronto, Ontario, Canada, and in Los Angeles, California. In Toronto, 19% of those contacted over 2 months donated $8,000 ($4,000/month) of goods and services. In Los Angeles, nearly 26% of those contacted over 34 months donated $161,000 ($4,472/month) of goods and services. Maintaining voucher programs by soliciting donations is feasible and sustainable. The methods in this article can serve as a guide for successful donation solicitation campaigns. Donations offer an alternative for obtaining VBRT rewards for substance abuse treatment and may increase its dissemination. PMID:15122959

Quality management improvement has become a recent focus of attention in medical education. The program for the donation of bodies and body parts (Body Donation Program) at the University of Padova has recently been subjected to a global quality management standard, the ISO 9001:2008 certification. The aim of the present work is to show how the above standard is useful in enhancing the efficiency of body donation procedures and the quality and output of medical education. The program is managed by means of the following interlinked procedures: the collection of body donations, death certificates, data, and body parts from living donors; the transportation and identification of cadavers; the management of bodies, body parts, equipment, instruments, purchasing of necessary materials, and setting up anatomical training sessions; the management of preventive and corrective actions; the management of documents and registration; the management of internal and external quality audits; and the review of outcomes and improvement planning. Monitoring indicators are identified in the numbers of donors and of donated body parts per year, education sessions, and satisfaction of learners and donors, as evaluated by questionnaires. The process management approach, the integrated involvement of medical, technical, and administrative staff in defining procedures, and the application of monitoring indicators allow quality improvement in all aspects of the Body Donation Program.

Phloretin-2'-O-glycosyltransferase (P2'GT) catalyzes the last glycosylation step in the biosynthesis of phloridzin that contributes to the flavor, color and health benefits of apples and processed apple products. In this work, a novel P2'GT of Malus x domestica (MdP2'GT) with a specific activity of 46.82 μkat/Kg protein toward phloretin and uridine diphosphate glucose (UDPG) at an optimal temperature of 30 °C and pH 8.0 was purified from the engineered Pichia pastoris broth to homogeneity by anion exchange chromatography, His-Trap affinity chromatography and gel filtration. The purified MdP2'GT was low N-glycosylated and secreted as a stable dimer with a molecular mass of 70.7 kDa in its native form. Importantly, MdP2'GT also exhibited activity towards quercetin and adenosine diphosphate glucose (ADPG), kaempferol and UDPG, quercetin and UDP-galactose, isoliquiritigenin and UDPG, and luteolin and UDPG, producing only one isoquercitrin, astragalin, hyperoside, isoliquiritin, or cynaroside, respectively. This broad spectrum of activities make MdP2'GT a promising biocatalyst for the industrial preparation of the corresponding polyphenol glycosides, preferably for their subsequent isolation and purification. Besides, MdP2'GT displayed the lowest K m and the highest k cat /K m for phloretin and UDPG compared to all previously reported P2'GTs, making MdP2'GT favor phloridzin synthesis the most.

Microbial Pattern-recognition receptors (PRRs), such as nucleotide-binding oligomerization domains (NODs), are essential for mammalian innate immune response. This study was designed to determine the effect of NOD1 and NOD2 agonist on innate immune responses and antitumor activity in oral squamous cell carcinoma (OSCC) cells. NODs expression was examined by RT-PCR, and IL-8 production by NODs agonist was examined by ELISA. Western blot analysis was performed to determine the MAPK activation in response to their agonist. Cell proliferation was determined by MTT assay. Flow cytometry and Western blot analysis were performed to determine the MDP-induced cell death. The levels of NODs were apparently expressed in OSCC cells. NODs agonist, Tri-DAP and MDP, led to the production of IL-8 and MAPK activation. NOD2 agonist, MDP, inhibited the proliferation of YD-10B cells in a dose-dependent manner. Also, the ratio of Annexin V-positive cells and cleaved PARP was increased by MDP treatment in YD-10B cells, suggesting that MDP-induced cell death in YD-10B cells may be owing to apoptosis. Our results indicate that NODs are functionally expressed in OSCC cells and can trigger innate immune responses. In addition, NOD2 agonist inhibited cell proliferation and induced apoptosis. These findings provide the potential value of MDP as novel candidates for antitumor agents of OSCC. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Methyl-tert-butyl ether (MTBE) and its degradation by-product, tert-butyl alcohol (TBA), are widespread contaminants detected frequently in groundwater in California. Since MTBE was used as a fuel oxygenate for almost two decades, leaking underground fuel storage tanks are an important source of contamination. Gasoline components such as BTEX (benzene, toluene, ethylbenzene and xylenes) are often present in mixtures with MTBE and TBA. Investigations of interactions between BTEX and MTBE degradation have not yielded consistent trends, and the molecular mechanisms of BTEX compounds' impact on MTBE degradation are not well understood. We investigated trends in transcription of biodegradation genes in the MTBE-degrading bacterium, Methylibium petroleiphilum PM1 upon exposure to MTBE, TBA, ethylbenzene and benzene as individual compounds or in mixtures. We designed real-time quantitative PCR assays to target functional genes of strain PM1 and provide evidence for induction of genes mdpA (MTBE monooxygenase), mdpJ (TBA hydroxylase) and bmoA (benzene monooxygenase) in response to MTBE, TBA and benzene, respectively. Delayed induction of mdpA and mdpJ transcription occurred with mixtures of benzene and MTBE or TBA, respectively. bmoA transcription was similar in the presence of MTBE or TBA with benzene as in their absence. Our results also indicate that ethylbenzene, previously proposed as an inhibitor of MTBE degradation in some bacteria, inhibits transcription of mdpA, mdpJ and bmoAgenes in strain PM1.

To investigate the efficacy and safety of technetium-99 conjugated with methylene diphosphonate ( 99 Tc-MDP, Yunke Pharmaceutical industry) in the treatment of rheumatoid arthritis (RA). A total of 120 patients with active RA were randomly divided into three groups: Group A (receiving oral meloxicam tablets); Group B (receiving intravenous drip of 99 TC-MDP); Group C (receiving combination treatment of intravenous drip of 99 Tc-MDP and oral meloxicam tablets). The main clinical and laboratory parameters were evaluated at baseline and after 14 days of therapy. After 14 days of treatment, American College of Rheumatology 20 response was 15.62%, 34.04% and 48.78% in the three groups, respectively. The incidence of adverse events in three groups were 3.13%, 8.51% and 9.76% respectly, and has no significant difference. In addition, biochemical markers of bone metabolism including bone alkaline phosphatase (BAP), tartrate resistant acid phosphatase (TRAP) and dickkopf-1 (DKK-1), all improved in the three groups, although more significant in Group B than Group A, and more significant in the combination group than monotherapy groups. 99 Tc-MDP has good efficacy and safety in the treatment of active RA patients; the benefit was more remarkable when 99 Tc-MDP was combined with NSAIDs. 99 Tc-MDP may also have potential to improve bone metabolism. © 2017 Asia Pacific League of Associations for Rheumatology and John Wiley & Sons Australia, Ltd.

The organ donation rate in Japan is much lower than that in other developed countries for several reasons. An advanced educational program for in-hospital procurement coordinators is a possible solution for this. We introduced a Transplant Procurement Management (TPM) educational program at Hyogo Prefecture, Japan. Ten healthcare professionals at Hyogo Prefecture participated in the Advanced International TPM course to educate themselves on TPM and held 2 TPM Model Organ Procurement Training Workshops at Hyogo Prefecture for in-hospital procurement coordinators. Furthermore, we held 2 workshops outside Hyogo Prefecture and at the same time undertook a pre-workshop questionnaire survey to evaluate the ability and motivation with respect to organ donation. To evaluate the effectiveness of the workshops, we conducted post-workshop and 3-months-after workshop questionnaire surveys. The results of the pre-workshop survey revealed that in-hospital procurement coordinators lacked the knowledge regarding the entire organ donation process, the current status of organ donation in Japan, and the definition of brain death. Moreover, they did not completely understand the meaning of "organ donation." The results of the post-workshop questionnaire survey showed that the educational program was effective to improve the knowledge and skills of organ donation and motivated behavioral changes among the participants. The survey results showed that our TPM model educational program offered sufficient knowledge and skills to increase organ donation at Hyogo Prefecture. We will continue this program and make an effort to further contribute to the Japanese organ donation activities. Copyright © 2016 Elsevier Inc. All rights reserved.

The 3-hour biodistribution of /sup 99m/Tc complexes of five diphosphonates (HMDP, NMMDP, DMAD, DPD, and APD), imidodiphosphonate (IDP), and pyrophosphate (PYP) was compared in rats with segmental renal infarction induced by a 1-hour occlusion of a renal artery branch. /sup 95m/Tc labeled MDP was a reference substance in all animals. Three agents (APD, HMDP and IDP) had a higher infarct/normal kidney concentration ratio than MDP, the latter two by virtue of a lower content in normal kidney. HMDP, DPD, and IDP had very high liver concentrations. DPD showed relatively high concentrations in soft tissues and blood. The blood and kidneymore » levels of PYP were higher than those of MDP but the infarct/normal kidney ratios were similar. None of the agents had a higher uptake in bone than MDP: four had a significantly lower uptake. The increased concentration of /sup 99m/Tc MDP in the infarcts was readily seen in camera images one day after renal artery occlusion, but not at three or seven days. Increased diphosphonate uptake was accompanied by an influx of calcium in both cortex and medulla. The accumulation of diphosphonate in areas of infarction was not modified by infusions of verapamil or Captopril.« less

Cadavers play an important role in anatomy education. In Australia, bodies for anatomy education are acquired only through donations. To gain insight into educational dynamics in an anatomy laboratory as well as to facilitate body donation programs and thanksgiving ceremonies, it is important to understand students' attitudes toward body donation. In this cross-sectional study, the attitudes of Macquarie University's first, second, and fifth year chiropractic students toward body donation were investigated. Macquarie University chiropractic students have a four semester long anatomy program, which includes cadaver-based instruction on prosected specimens. A questionnaire was used to record respondents' demographics and attitudes toward body donation: personal, by a relative, and by a stranger. It was found that ethnicity and religion affect attitudes toward body donation, with Australian students being more willing to donate a stranger's body and atheists and agnostics being more willing to donate in general. Furthermore, willingness to donate one's own or a family member's body decreases as year of study increases, suggesting a possible negative impact of exposure to cadavers in the anatomy laboratory. This was only true, however, after controlling for age. Thus, the impact of viewing and handling prosected specimens, which is the norm in anatomy classes in Australia, may not be as strong as dissecting cadavers. It is suggested that anatomists and educators prepare students for cadaver-based instruction as well as exhibit sensitivity to cultural differences in how students approach working with cadavers, when informing different communities about body donation programs and in devising thanksgiving ceremonies. © 2013 American Association of Anatomists.

The growing demand for organs continues to outpace supply. This gap is most pronounced in minority populations, who constitute more than 40% of the organ waiting list. Hispanic Americans are particularly less likely to donate compared with other minorities for reasons that remain poorly understood and difficult to change. To determine whether outreach interventions that target Hispanic Americans improve organ donation outcomes. Prospective before-after study of 4 southern California neighborhoods with a high percentage of Hispanic American residents. We conducted cross-sectional telephone surveys before and 2 years after outreach interventions. Respondents 18 years or older were drawn randomly from lists of Hispanic surnames. Awareness, perceptions, and beliefs regarding organ donation and intent to donate were measured and compared before and after interventions. Television and radio commercials about organ donation and educational programs at 5 high schools and 4 Catholic churches. Number of survey participants who specify intent to donate. A total of 402 preintervention and 654 postintervention individuals participated in the surveys. We observed a significant increase in awareness of and knowledge about organ donation and a significant increase in the intent to donate (17.7% vs 12.1%; adjusted odds ratio, 1.55 [95% CI, 1.06-2.26; P = .02]). Focused donor outreach programs sustain awareness and knowledge and can significantly improve intent to donate organs in the Hispanic American population. These programs should continue to be evaluated and implemented to influence donor registration.

The purpose of this study was to determine whether oral immunization of ferret kits with a whole-cell sonicate of Helicobacter mustelae lysate (Hml) and the adjuvant muramyl dipeptide (MDP) would reduce the incidence of natural colonization with H. mustelae and the extent of Helicobacter-associated gastritis by enhancing the host mucosal immune response. Between the ages of 4 and 11 weeks, 44 ferret kits were gavaged with Hml and various doses of MDP. The extent of gastritis and duodenitis and the immune response to H. mustelae were evaluated. All kits became colonized naturally with H. mustelae and the majority developed mild to severe gastritis and duodenitis. Kits that received Hml with MDP developed significantly greater inflammation of the gastric antrum and duodenum, as compared to kits vaccinated with Hml alone. Vaccination with Hml and 50 micrograms of MDP was associated with severe lesions in the proximal duodenum characterized by accumulation of mononuclear inflammatory cells, mucosal erosion, and ulceration. Although serum antibody specific for H. mustelae in 4-week-old kits was approximately 50% of adult levels, a finding attributable to passively acquired maternal antibody, both systemic and mucosal antibody levels became depressed over time despite oral vaccination. The humoral immune response was sufficiently low to prevent detection of any significant dose effect of MDP on antibody levels among experimental groups. Oral vaccination of young ferrets with Hml and 50 micrograms MDP increased the risk of Helicobacter-associated mucosal ulceration in the proximal duodenum, which was associated with low humoral (but significant cell-mediated) immune responses to H. mustelae. In retrospect, the frequency of vaccination may have suppressed the systemic humoral immune response, thereby promoting mucosal damage by H. mustelae. The 50-microgram dose of MDP enhanced the cell-mediated immune response, which indirectly contributed to development of severe lesions. The increased frequency of mucosal damage associated with this vaccination regimen enhances the value of the ferret model for studying duodenal ulceration secondary to Helicobacter infection.

Lead (Pb) is a toxic metal, frequently associated with occupational exposure, due to its widespread use in industry and several studies have shown high Pb levels in workers occupationally exposed to the metal. The aim of this study was to evaluate the influence of milk and dairy products (MDP) on Pb levels in blood (B-Pb), plasma (P-Pb), and urine (U-Pb), in workers from automotive battery industries in Brazil. The study included 237 male workers; information concerning diet and lifestyle were gathered through a questionnaire, and B-Pb, P-Pb, and U-Pb were determined by ICP-MS. Mean B-Pb, P-Pb, and U-Pb were 21 ± 12, 0.62 ± 0.73 μg/dL, and 39 ± 47 μg/g creatinine, respectively. Forty three percent of participants declared consuming ≤3 portions/week of MDP (classified as low-MDP intake), while 57% of individuals had >3portions/week of MDP (high-MDP intake). B-Pb and P-Pb were correlated with working time (r s = 0.21; r s = 0.20; p < 0.010). Multivariable linear regressions showed a significant influence of MDP intake on B-Pb (β = -0.10; p = 0.012) and P-Pb (β = -0.16; p < 0.010), while no significance was seen on U-Pb. Our results suggest that MDP consumption may modulate Pb levels in individuals highly exposed to the metal; these findings may be due to the Pb-Ca interactions, since the adverse effects of Pb are partially based on its interference with Ca metabolism and proper Ca supplementation may help to reduce the adverse health effects induced by Pb exposure.

1. In the present study, we investigated the effects of technetium-99 conjugated with methylene diphosphonate ((99)Tc-MDP), an agent used in radionuclide therapy, on receptor activator of nuclear factor-κB ligand (RANKL)-induced osteoclastogenesis and explored the underlying mechanisms. 2. The murine macrophage cell line RAW264.7 and bone marrow-derived-macrophages from C57BL/6 mice (BMM) were used as models for osteoclastogenesis in vitro. The expression of some key factors in RANKL (50 ng/mL)-induced osteoclastogenesis in RAW264.7 cells was investigated by flow cytometry and real-time reverse transcription-polymerase chain reaction (RT-PCR). To detect multinucleated osteoclast formation, RAW264.7 cells were induced with RANKL for 4 days, whereas BMM were induced by 50 ng/mL RANKL and 20 ng/mL macrophage colony-stimulating factor for 7 days, before being stained with tartrate-resistant acid phosphatase. 3. Osteoclastogenesis was evaluated using the osteoclast markers CD51, matrix metalloproteinase (MMP)-9 and cathepsin K. At 0.01 μg/mL, (99)Tc-MDP significantly inhibited RANKL-induced osteoclastogenesis without any cytotoxicity. In addition, (99)Tc-MDP abolished the appearance of multinucleated osteoclasts. 4. Real-time RT-PCR analysis of transcription factor expression revealed that (99)Tc-MDP inhibited the expression of c-Fos and nuclear factor of activated T cells. In addition, (99)Tc-MDP inhibited the expression of the inflammatory factors interleukin (IL)-6, tumour necrosis factor-α and IL-1β. Finally, (99)Tc-MDP inhibited the activation of mitogen-activated protein kinases in RAW264.7 cells following RANKL stimulation. 5. In conclusion, (99)Tc-MDP possesses anti-osteoclastogenic activity against RANKL-induced osteoclast formation. © 2012 The Authors Clinical and Experimental Pharmacology and Physiology © 2012 Wiley Publishing Asia Pty Ltd.
Altered [99mTc]Tc-MDP biodistribution from neutron activation sourced 99Mo.

Given potential worldwide shortages of fission sourced 99 Mo/ 99m Tc medical isotopes there is increasing interest in alternate production strategies. A neutron activated 99 Mo source was utilized in a single center phase III open label study comparing 99m Tc, as 99m Tc Methylene Diphosphonate ([ 99m Tc]Tc-MDP), obtained from solvent generator separation of neutron activation produced 99 Mo, versus nuclear reactor produced 99 Mo (e.g., fission sourced) in oncology patients for which an [ 99m Tc]Tc-MDP bone scan would normally have been indicated. Despite the investigational [ 99m Tc]Tc-MDP passing all standard, and above standard of care, quality assurance tests, which would normally be sufficient to allow human administration, there was altered biodistribution which could lead to erroneous clinical interpretation. The cause of the altered biodistribution remains unknown and requires further research.

A pilot test of a computer-tailored intervention designed to promote blood donation among Blacks was conducted. Intervention content, based on the transtheoretical model, offered participants individually and culturally tailored information on blood donation with emphasis on need specific to race (e.g., sickle-cell disease). Black adults (N = 150) with a diversity of blood donation experience were recruited from a blood center and a survey recruitment website. Posttest assessment included a 14-item evaluation and transtheoretical model questions. Participants rated the program positively (81.3% to 98.7% of participants agreeing or strongly agreeing with evaluation items). For example, 98.7% of respondents reported that the program gave sound advice and that personal feedback was easily understood, and 87.3% felt the program was designed for people like themselves. Ninety-five percent of participants reported that they would recommend the program to others. There were no significant differences in ratings based on demographics. Qualitative responses support program acceptability. Furthermore, pre- and postprogram assessments indicated an increase in intention to donate, t(149) = 3.56, p = .001, d = .29. With acceptability and feasibility confirmed, the next steps are to test efficacy and cost-effectiveness for use to increase blood donation, particularly in priority populations. © 2014 Society for Public Health Education.

The European Union Food Distribution programme for the Most Deprived Persons (MDP) of the community ran from 1987 until 2013. It was funded from Common Agricultural Policy budgets. The programme initially made use of surplus foods from the food mountains resulting from intervention stocks. This food was then distributed through aid agencies within member states, coordinated at a national government level. Reform of the CAP and global rises in food prices resulted in an increase in budget from €300 to €500 million Euros in 2010 with the added power to buy food on the open market. This led to a formal challenge to the scheme on the basis that buying goods on the open market shifted the emphasis from an agricultural/financial basis to a social one. A court ruling found that because the program was no longer used for removing surpluses the link to agriculture policy has become tenuous and therefore had no basis in community law. As a result of this legal challenge a number of policy compromises ensured the MDP would continue until the end of 2013 with a reduced budget. The scheme has been superseded by a new scheme in March 2014 called the Fund for European Aid to the Most Deprived (FEAD). This is seen as a social programme. The way that policy and politics developed and changed the MDP programme are set out. The article tracks its move from being an agricultural policy to a social welfare one. The key policy players and actors in this move are set out as are the changing context and policy frameworks. The replacement of the MDP by FEAD is discussed as is how intensive lobbying in 2012/13 resulted in the development of a new Fund for European Aid to the Most Deprived (FEAD).

During the Microbicides Development Program (MDP) 301, a clinical trial of a candidate microbicide amongst women in Johannesburg, South Africa, we used community radio to promote awareness of the trial, to inform community members about specific medical research procedures and terminologies, and to stimulate dialogue between researchers and local citizens. We used mixed methods to undertake a retrospective analysis of the social responses to the radio shows, focusing specifically on recruitment and participation in the MDP301 trial. We collected quantitative data that describes the themes and listener responses, the costs per broadcast, and the impact of the radio broadcasts on trial recruitment. Qualitative data on local reactions to the shows was gleaned from in-depth interviews with trial participants. Over a seven-year period, 205 individual broadcasts were made on two separate community radio stations. Show themes were either specifically related to medical research issues (36%), or focused on general health issues (46%), and sexual and reproductive health, including HIV prevention (18%). 403 listeners made telephone calls to the radio station, and 12% of women enrolled as participants in MDP301 (n = 9, 385) reported that they had first heard about the trial from the radio. Qualitative interviews (n = 401) with female MDP301 participants highlighted the effects of the radio shows in making women aware of the trial, impressing them with the importance of health screening and knowledge, legitimizing trial participation, and stimulating dialogue between trial participants and their male partners. Community radio is a potent tool for raising awareness and local knowledge about medical research and, in addition to other methodologies, can be used to promote recruitment into clinical trials. We suggest that future HIV prevention trials consider an investment in community radio beyond recruitment advertisements that incorporates this into the broader community engagement plan as a key element of Good Participatory Practice in clinical trial settings.
Family communication coordination: a program to increase organ donation.
Linyear, A S; Tartaglia, A
1999-09-01
To improve organ donation performance, the Medical College of Virginia Hospitals implemented a comprehensive family support and communication program, consisting of a standard family communications protocol, a hospital-based team from the Department of Pastoral Care, targeted staff education, and an ongoing quality assurance measuring and monitoring system. The 3 best-demonstrated request practices, private setting, "decoupling," and collaboration in the request between the organ procurement organization and hospital staff, were incorporated into the program. Improvement in the consent and donation rate was evident in the second calendar year of the program; the consent rate was 72% and the donation rate was 50%. During the second year, there was also a positive correlation between "decoupling," appropriate requestor, and the consent rate. Implementation of a hospital-based team and a standard protocol facilitated the clarification of roles and responsibilities toward clearer and more consistent family communication and support. Data suggest that staff experience is a major contributor to a positive donation outcome.

This in vitro study evaluated the marginal gap, cement thickness, and microleakage of glass-ionomer cement (GIC) and phosphate monomer-containing resin cement (MDP-RC) under 2 zirconia crown systems (Cercon and DC-Zirkon). Forty human premolars were prepared for all-ceramic zirconia crowns with a 1 mm circumferential finish line and a 1.5 mm occlusal reduction. The crowns (n = 10 per group) from each zirconia system were randomly divided into 2 groups and cemented either with GIC (Vivaglass CEM) or MDP-RC (Panavia F 2.0) cement. The cemented crowns were thermocycled 5000 times (5°-55°C). The crowns were immersed in 0.5% basic fuchsine dye solution for 24 hours and sectioned buccolingually and mesiodistally. Specimens were examined under optical microscope (100X). Data were analyzed using Student t-test and chi-square tests (α = 0.05). Mean marginal gap values for Cercon (85 ± 11.4 μm) were significantly higher than for DC-Zircon (75.3 ± 13.2 μm) (P = 0.018). The mean cement thickness values of GIC (81.7 ± 13.9 μm) and MDP-RC (78.5 ± 12.5 μm) were not significantly different (P = 0.447). Microleakage scores did not demonstrate significant difference between GIC (P = 0.385) and MDP-RC (P = 0.631) under Cercon or DC-Zircon. Considering the cement thickness values and microleakage scores obtained, both zirconia crown systems could be cemented in combination with either GIC or MDP-RC.

Hurricanes Katrina and Rita showed the vulnerability of coastal communities and how human activities that caused deterioration of the Mississippi Deltaic Plain (MDP) exacerbated this vulnerability. The MDP formed by dynamic interactions between river and coast at various temporal and spatial scales, and human activity has reduced these interactions at all scales. Restoration efforts aim to re-establish this dynamic interaction, with emphasis on reconnecting the river to the deltaic plain. Science must guide MDP restoration, which will provide insights into delta restoration elsewhere and generally into coasts facing climate change in times of resource scarcity.

This study aimed to quantify the adsorption affinity of neutralized 10-methacryloyloxydecyl dihydrogen phosphate (10-MDP-N) toward hydroxyapatite (HA) and dicalcium phosphate dihydrate (DCPD) at pH 7.0 by employing the Langmuir isotherm model. Furthermore, the effects of inorganic phosphate (Pi) and fluoride (F(-) ) ions on the adsorption of 10-MDP-N onto HA and DCPD were examined. Fixed amounts of HA and DCPD powders were suspended in different concentrations of 10-MDP-N solutions and were incubated for 18 h. Equilibrated concentrations of 10-MDP-N were measured by spectrophotometry and the adsorption affinity was estimated using the Langmuir model. Moreover, the adsorption was examined by zeta-potential analysis. The results indicated that significant Langmuir correlation was noted in both substrates, along with an increasing negative zeta-potential; however, in DCPD the correlation was less strong. The addition of 1.0 mM Pi slightly delayed the adsorption of 10-MDP-N onto both substrates, whereas 3.0 mM Pi drastically delayed adsorption onto HA but completely inhibited adsorption onto DCPD. Up to 50 ppm, F(-) enhanced the adsorption onto HA, and the adsorption plateaued at higher concentrations of F(-) , whereas no obvious influence of F(-) on the adsorption onto DCPD was noted. © 2016 Eur J Oral Sci.

As the critical dimension (CD) becomes smaller, various resolution enhancement techniques (RET) are widely adopted. In developing sub-100nm devices, the complexity of optical proximity correction (OPC) is severely increased and applied OPC layers are expanded to non-critical layers. The transformation of designed pattern data by OPC operation causes complexity, which cause runtime overheads to following steps such as mask data preparation (MDP), and collapse of existing design hierarchy. Therefore, many mask shops exploit the distributed computing method in order to reduce the runtime of mask data preparation rather than exploit the design hierarchy. Distributed computing uses a cluster of computers that are connected to local network system. However, there are two things to limit the benefit of the distributing computing method in MDP. First, every sequential MDP job, which uses maximum number of available CPUs, is not efficient compared to parallel MDP job execution due to the input data characteristics. Second, the runtime enhancement over input cost is not sufficient enough since the scalability of fracturing tools is limited. In this paper, we will discuss optimum load balancing environment that is useful in increasing the uptime of distributed computing system by assigning appropriate number of CPUs for each input design data. We will also describe the distributed processing (DP) parameter optimization to obtain maximum throughput in MDP job processing.

The altruistic act of body donation provides a precious resource for both teaching and researching human anatomy. However, relatively little is known about individuals who donate their bodies to science (donors), and in particular whether donors in different geographical locations share similar characteristics. A multicenter prospective survey of donors registering during 2010 in three different geographical locations, New Zealand, Ireland, and the Republic of South Africa, was conducted to identify donor characteristics. The 28-question survey included sections on body donation program awareness, reasons for donating, giving tendency, education, ethnicity, relationship status, occupation, religion, and political preference. Two hundred surveys (81%) were returned [New Zealand 123 (85% response rate), Republic of South Africa 41 (67%), and Ireland 36 (92%)]. Results indicate that donors share certain characteristics including reason for donating (80% cited a desire to aid medical science as the main reason for wishing to donate their body); family structure (most donors are or have been in long-term partnerships and ≥ 85% have siblings); and a higher proportion with no religious affiliation compared to their reference population. Some variations between locations were noted including donor age, the mode of program awareness, occupation, relationship status, political preference, organ donor status and with whom donors had discussed their decision to donate. This information could be important for assisting the identification of potential body donors in new and established bequest programs. Copyright © 2012 American Association of Anatomists.

To evaluate the clinical efficacy and safety in patients with refractory ankylosing spondylitis (AS) initiating 99Tc-MDP therapy and explore the mechanisms. Refractory AS patients were enrolled in the clinical trial and received 99Tc-MDP treatments for 3 or 5 courses according to ASAS improvement. Efficacy and safety evaluations were conducted during the follow-up. 37 cytokines were quantified by Luminex at baseline and week 30. p-values<0.05 were considered statistically significant. 51 refractory AS patients were included, with 20 healthy people serving as the control group. The patients were in an active disease state (mean (SD) ASDAS 3.66 (0.83), BASDAI 4.53 (1.92)), 42(82.35%) patients had syndesmophytes. Their cytokines were significantly higher than that in the control group. After 3 courses of 99Tc-MDP treatment, 32 (62.75%) patients achieved ASAS20 improvement, 24 (47.06%) patients achieved a clinically significant improvement (ΔASDAS-CRP≥1.1). 27 patients entered the second stage to complete 5 courses of the treatment, all of whom achieved ASAS20 improvement, 18 (66.67%) patients achieved a clinically significant improvement. All clinical parameters including ASAS and ASDAS significantly improved as the treatment was continued. Cytokines also had significant down-regulation after the treatment, and the reductions had positive correlations with the improvements of disease activity. No serious adverse event was observed. This investigation confirmed the remarkable efficacy of 99Tc-MDP in a large number of refractory AS patients, and highlighted the mechanism by dramatic regulation on cytokines. 99Tc-MDP was safe in clinical application.

Creating an alkaline environment prior to 10-methacryloyloxydecyldihydrogenphosphate (MDP) conditioning improves the resin bonding of zirconia. The present study evaluated the effects of four alkaline coatings with different water solubilities and pH values on resin bonding of MDP-conditioned zirconia. Two alkaline nanoparticle coatings were studied in particular. Thermodynamics calculations were performed to evaluate the strengths of MDP-tetragonal phase zirconia chemical bonds at different pH values. Zirconia surfaces with and without alkaline coatings were characterized by scanning electron microscope (SEM)/energy dispersive spectrometer and Fourier transform infrared spectroscopy; alkaline coatings included NaOH, Ca(OH) 2 , nano-MgO, and nano-Zr(OH) 4 . A shear bond strength (SBS) test was performed to evaluate the effects of the four alkaline coatings on bonding; the alkaline coatings were applied to the surfaces prior to conditioning the zirconia with MDP-containing primers. Gibbs free energies of the MDP-tetragonal zirconia crystal model coordination reaction in different pH environments were -583.892 (NaOH), -569.048 [Ca(OH) 2 ], -547.393 (MgO), and -530.279 kJ/mol [Zr(OH) 4 ]. Thermodynamic calculations indicated that the alkaline coatings improved bonding in the following order: NaOH > Ca(OH) 2 > MgO > Zr(OH) 4 . Statistical analysis of SBS tests showed a different result. SBSs were significantly different in groups that had different alkaline coatings, but it was not influenced by different primers. All four alkaline coatings increased SBS compared to control groups. Of the four coatings, nano-Zr(OH) 4 and -MgO showed higher SBS. Therefore, preparing nano-Zr(OH) 4 or -MgO coatings prior to conditioning with MDP-containing primers may potentially improve resin bonding of zirconia in the clinic.

Multidisciplinary disease management programmes (MDPs) for heart failure have been shown to be effective in Western countries. However, it is not known whether they improve outcomes in a high population density country with a national health insurance programme. In total, 349 patients hospitalized because of heart failure were randomized into control and MDP groups. All-cause death and re-hospitalization related to heart failure were analyzed. The median follow-up period was approximately 2 years. Mean patient age was 60 years; 31% were women; and 50% of patients had coronary artery disease. MDP was associated with fewer all-cause deaths [hazard ratio (HR) = 0.49, 95% confidence interval (CI) = 0.27-0.91, P = 0.02] and heart failure-related re-hospitalizations (HR = 0.44, 95% CI = 0.25-0.77, P = 0.004). MDP was still associated with better outcomes for all-cause death (HR = 0.53, 95% CI = 0.29-0.98, P = 0.04) and heart failure-related re-hospitalization (HR = 0.46, 95% CI = 0.26-0.81, P = 0.007), after adjusting for age, diuretics, diabetes mellitus, chronic kidney disease, hypertension, sodium, and albumin. However, MDPs' effect on all-cause mortality and heart failure-related re-hospitalization was significantly attenuated after adjusting for angiotensin-converting enzyme inhibitors/angiotensin II receptor blockers or β-blockers. A stratified analysis showed that MDP combined with guideline-based medication had synergistic effects. MDP is effective in lowering all-cause mortality and re-hospitalization rates related to heart failure under a national health insurance programme. MDP synergistically improves the effectiveness of guidelines-based medications for heart failure.

Tanaidaceans are small benthic crustaceans with a strictly benthic life cycle and low dispersion rates, so they are good candidates to evaluate the effects of environment over life history strategies and reproductive biology. In this work, we studied two populations of Tanais dulongii (Audouin, 1826) that live in two contrasting habitats in order to determine whether they differ in life history traits. The animals were obtained by systematic sampling in a rocky shore with a lower anthropic impact (La Estafeta: LE) and a polluted area (Mar del Plata harbour: MdP) from March 2011 to March 2012. Seawater temperature and salinity did not differ between sites, but MdP showed more acid and hypoxic conditions than LE. Population density was homogeneous and lower in MdP (ca. 20 ind/100 gr) than that in LE where density varied between 250 and 800 ind/100 gr. Reproductive individuals and juveniles were always present, and both populations showed two main recruitment periods: the first in spring in both populations, and the second in summer in MdP but in autumn-winter in LE. In both populations, sex ratio was strongly female-biased. Juveniles, females and males from LE had larger sizes than that from MdP and reached their sexual differentiation at larger sizes. The estimated lifespan was about 9 and 12 months in MdP and LE, respectively. This study suggests that the differences observed between populations of T. dulongii in life history traits are intimately related to environmental differences in pH and dissolved oxygen between habitats, but should not be discarded a synergistic effect of temperature, organic pollution, food availability and predation pressure.

Low bioavailability of oral manidipine (MDP) is due to its low water solubility. The objective of this study was to increase the solubility and bioavailability of MDP by fabricating ternary solid dispersion (tSD) with d-α-tocopherol polyethyleneglycol-1000-succinate and copovidone. In this study, solid ternary phase diagram was applied in order to check the homogeneity of tSD prepared by melting and solidifying with dry ice. The physicochemical properties of different formulations were determined by differential scanning calorimetry (DSC), powder X-ray diffraction (PXRD), Fourier transform infrared spectroscopy (FTIR) and hot stage microscopy. Their solubility, dissolution, stability and bioavailability were also investigated. The results demonstrated that tSD obtained from ternary phase diagram divided into homogeneous and non-homogeneous regions. In the homogenous region, the transparent characteristics of tSD was observed and considered as a glass solution, which have a higher MDP solubility than that in non-homogenous region. The hot stage microscopy, DSC and PXRD confirmed that solid dispersion was formed in which MDP was molecularly dispersed in the carriers, especially in the homogenous region of phase diagram. FTIR analysis demonstrated strong hydrogen bonding between amine groups of MDP and carbonyl groups of copovidone, which supported a higher solubility and dissolution of tSD. The pharmacokinetic study in Wistar rats showed that the tSD had the greatest effect on oral bioavailability. Immediate hypotensive effect of tSD was also observed in vivo. The improvement of stability, dissolution and oral bioavailability of MDP could be achieved by using tSD technique.

Body donation in India: social awareness, willingness, and associated factors.
Rokade, Shrikant A; Gaikawad, Anjana P
2012-01-01
With the attendant rise of the number of medical colleges in India over past few decades, the demand for cadavers used in medical education and research is growing. However, there is an insufficient supply of donated cadavers available for dissection. This study was undertaken to assess the general population's awareness of body donation programs and willingness to donate in the State of Maharashtra, India. The willingness of participants to donate was compared with age, gender, and education of the respondents. A total of 625 adult individuals from the State of Maharashtra participated in a survey composed of questions about age, sex, education, awareness of body donation programs, and willingness to donate. It was found that 90.9% of the medical colleges surveyed reported an inadequate supply of cadavers. Of the general population, 32.1% of respondents were aware of body donation, compared to 95.83% of health care professionals. However, only 19.5% of the general population and 44.9% of health care professionals were willing to donate their bodies for anatomical education. Younger age groups, males, graduates, and postgraduates were found more willing to donate their bodies. Organ donation was preferred over body donation. A lack of awareness about body donation was the main factor responsible for respondents' "no body donation" response in the general population, along with firm religious beliefs and customs, the fear that the donated body will not be treated with respect and dignity, and the unacceptability of the dissection of one's own body. To overcome the current shortage of donated cadavers, efforts should be undertaken to change the mindset of the wider Indian society toward body donation. The authors believe this is possible through awareness campaigns and that prospective donors' concerns should be addressed appropriately. Proper guidance and assistance regarding body donation should be easily available for potential donors. Copyright © 2012 American Association of Anatomists.
Human NOD2 Recognizes Structurally Unique Muramyl Dipeptides from Mycobacterium leprae
Schenk, Mirjam; Mahapatra, Sebabrata; Le, Phuonganh; Kim, Hee Jin; Choi, Aaron W.; Brennan, Patrick J.; Belisle, John T.

The innate immune system recognizes microbial pathogens via pattern recognition receptors. One such receptor, NOD2, via recognition of muramyl dipeptide (MDP), triggers a distinct network of innate immune responses, including the production of interleukin-32 (IL-32), which leads to the differentiation of monocytes into dendritic cells (DC). NOD2 has been implicated in the pathogenesis of human leprosy, yet it is not clear whether Mycobacterium leprae, which has a distinct MDP structure, can activate this pathway. We investigated the effect of MDP structure on the innate immune response, finding that infection of monocytes with M. leprae induces IL-32 and DC differentiation in a NOD2-dependent manner. The presence of the proximal l-Ala instead of Gly in the common configuration of the peptide side chain of M. leprae did not affect recognition by NOD2 or cytokine production. Furthermore, amidation of the d-Glu residue did not alter NOD2 activation. These data provide experimental evidence that NOD2 recognizes naturally occurring structural variants of MDP. PMID:27297389
Proanthocyanidins and Their Contribution to Sensory Attributes of Black Currant Juices.
Laaksonen, Oskar A; Salminen, Juha-Pekka; Mäkilä, Leenamaija; Kallio, Heikki P; Yang, Baoru

Black currant juices from five different cultivars were analyzed for composition, content, and mean degree of polymerization (mDP) of proanthocyanidins (PA) by UPLC-MS/MS. Juices contained both procyanidins (PC) and prodelphinidins (PD), but the PC-% varied significantly, from 28 to 82% of the total PA. In addition, high PD-% was related to high mDP and total PA content. Enzyme-assisted processing increased significantly total PA (5-14-fold), PD-% (12-65%), and mDP (1.8-6.2-fold) in the juices of all cultivars. Enzymatic treatment increased the contents of large PAs more than those of small PAs. The contents of PA and mDP were positively associated with the mouth-drying and puckering astringent characteristics. However, the PA content did not contribute to the bitter taste. Juices from the most bitter cultivars had the lowest contents of proanthocyanidins regardless of the processing method. This finding indicates the existence of other bitter compounds in black currants in addition to PA.

Our aim was to analyze acceptance of cadaveric and living organ donation for transplantation among resident doctors, given that they are the new professionals of medicine who will have to encourage and develop transplant programs. A random survey was performed on resident doctors in a third-level hospital with an organ transplant program which is accredited for undergraduate and postgraduate education (n = 171). Attitudes toward cadaveric and living donation were evaluated using a questionnaire including various psychosocial variables that might affect such attitudes. We used the Student t test and the chi-square test. The sample was composed of responses by 171 resident doctors of mean age 28 +/- 4 years with 56% women. Attitudes toward cadaveric donation were favorable in 92% (n = 157). As for living donation, the percentage in favor of nonrelated donation was low: 23% for kidney and 19% for liver. However, when the donation was from a relative, the percentages increased to levels similar to those of cadaveric donation, namely 88% and 85% for kidney and liver, respectively. No differences were observed in attitudes toward cadaveric or living donation according to various psychosocial variables. The trainee doctors showed favorable attitudes toward human cadaveric organ donation as well as living related donation, which suggests a relaunch of living donors in the near future. However, there was not much acceptance of nonrelated donation, as has also been seen in studies of the general public in our geographical area.

An analog of 1alpha,25-dihydroxyvitamin D3, 22-oxyacalcitriol (OCT), differentiated human monocytic THP-1 and U937 cells to express membrane CD14 and rendered the cells responsive to bacterial cell surface components. Both THP-1 and U937 cells expressed Toll-like receptor 4 (TLR4) on the cell surface and TLR4 mRNA in the cells, irrespective of OCT treatment. In contrast, OCT-treated U937 cells scarcely expressed TLR2 mRNA, while OCT-treated THP-1 cells expressed this transcript. Muramyldipeptide (MDP) by itself exhibited only a weak ability to induce secretion of inflammatory cytokines such as interleukin-8 (IL-8) in the OCT-differentiated THP-1 cells but showed marked synergistic effects with Salmonella lipopolysaccharide (LPS) or lipoteichoic acid (LTA) from Staphylococcus aureus, both of which exhibited strong activities. Combinatory stimulation with LPS plus LTA did not show a synergistic effect on OCT-differentiated THP-1 cells. Similar results were observed in OCT-differentiated U937 cells, although combination experiments were carried out only with MDP plus LPS. Anti-CD14 monoclonal antibody (MAb) MY4, anti-TLR4 MAb HTA125, and the synthetic lipid A precursor LA-14-PP almost completely inhibited the IL-8-inducing activities of LTA as well as LPS on OCT-treated THP-1 cells, but these treatments increased MDP activity. OCT-treated THP-1 cells primed with MDP exhibited enhanced production of IL-8 upon stimulation with LPS, while the cells primed with LPS showed no change in production upon stimulation with MDP. MDP up-regulated mRNA expression of an adapter molecule to TLRs, MyD88, to an extent similar to that for LPS in OCT-treated THP-1 cells. These findings suggested that LTA as well as LPS activated human monocytic cells in a CD14- and TLR4-dependent manner, whereas MDP exhibited activity in a CD14-, TLR4-, and probably TLR2-independent manner and exhibited synergistic and priming effects on the cells for cytokine production in response to various bacterial components.
Consumer-Operated Service Programs: monetary and donated costs and cost-effectiveness.
Yates, Brian T; Mannix, Danyelle; Freed, Michael C; Campbell, Jean; Johnsen, Matthew; Jones, Kristine; Blyler, Crystal R

Examine cost differences between Consumer Operated Service Programs (COSPs) as possibly determined by a) size of program, b) use of volunteers and other donated resources, c) cost-of-living differences between program locales, d) COSP model applied, and e) delivery system used to implement the COSP model. As part of a larger evaluation of COSP, data on operating costs, enrollments, and mobilization of donated resources were collected for eight programs representing three COSP models (drop-in centers, mutual support, and education/advocacy training). Because the 8 programs were operated in geographically diverse areas of the US, costs were examined with and without adjustment for differences in local cost of living. Because some COSPs use volunteers and other donated resources, costs were measured with and without these resources being monetized. Scale of operation also was considered as a mediating variable for differences in program costs. Cost per visit, cost per consumer per quarter, and total program cost were calculated separately for funds spent and for resources donated for each COSP. Differences between COSPs in cost per consumer and cost per visit seem better explained by economies of scale and delivery system used than by cost-of-living differences between program locations or COSP model. Given others' findings that different COSP models produce little variation in service effectiveness, minimize service costs by maximizing scale of operation while using a delivery system that allows staff and facilities resources to be increased or decreased quickly to match number of consumers seeking services.
Ethical and Logistical Issues Raised by the Advanced Donation Program "Pay It Forward" Scheme.
Ross, Lainie Friedman; Rodrigue, James R; Veatch, Robert M
2017-10-01
The advanced donation program was proposed in 2014 to allow an individual to donate a kidney in order to provide a voucher for a kidney in the future for a particular loved one. In this article, we explore the logistical and ethical issues that such a program raises. We argue that such a program is ethical in principle but there are many logistical issues that need to be addressed to ensure that the actual program is fair to both those who do and do not participate in this program. © The Author 2017.

[Can one authorize oocyte donation in the Grand Duchy of Luxembourg?].
Arendt, J
2012-01-01
In the case of early ovary extinction, the only way to have a child is either adoption or egg/embryo reception by donation. To day, egg donation is prohibited in Luxembourg by ministerial decision in 2003. Germ cell donation is part of artificial reproductive therapy. Oocyte donation, in particular, needs to be done by IVF treatment, which makes it more complicated then sperm donation What makes it more difficult is the fact that there are no oocyte bank yet. Today, prohibition encourages procreative tourism what only wealthy people can afford. Although donation programs are well established many questions arise about egg donation such as refunds, divulging information, women's age limit, health insurance participation.

In renal transplant, there is a well-known deficiency in organ supply relative to demand. Live donation provides superior results when compared with deceased donation including a better rate of graft success and fewer immunologic complications. This deficiency in organs leads to significant morbidity and mortality rates. Alternative avenues have been extensively explored that may expand the live donor pool. They include altruistic donation as well as paired and pooled exchange programs. Altruistic donation is a truly selfless act from a donor unknown to the recipient. Kidney paired donation involves 2 incompatible donor-recipient pairs swapping donors to produce compatibility. Pooled donation involves at least 2 pairs, and can take the form of domino chains in which altruistic input sets up a chain of transplants, in which each recipient's incompatible donor makes a donation for the next recipient. Despite application of these various methods, there lie extensive ethical issues surrounding them. Misconceptions frequently occur; for instance, the perceived benefit that donating an organ to a loved one is greater for a related donor than for an altruistic one. Additionally, it is frequently believed that immunologic incompatibility offers coerced donors liberation from surgery, and that overcoming these barriers by introducing exchange programs provides vulnerable donors less protection. This article explores these and other complex ethical issues surrounding the various methods of expanding the donor pool. The authors offer opinions that challenge the ethical issues and attempt to overcome those views that hinder progress in the field.

The Renal Unit of Obafemi Awolowo University Teaching Hospital Ile-Ife in Southwest Nigeria intends commencing a kidney transplantation program. This cross-sectional study aimed at examining the willingness of Nigerians to be living-related kidney donors. Three hundred and sixteen Nigerians (96 first-degree relatives of end-stage renal disease patients, 69 rural dwellers and 151 health workers) were interviewed regarding their willingness to donate kidneys using an interview schedule designed to elicit socio-demographic information, knowledge about kidney transplantation and attitude toward kidney donation. Sixty-two percent of health workers, 52.1% of the patients' relatives and 27.1% of rural dwellers expressed willingness to donate. Higher proportions of health workers and patients' relatives--compared with the rural dwellers--were willing to donate a kidney to their children, full-siblings and parents (P<0.05). The level of awareness about kidney transplantation was highest among health workers and least among rural dwellers (P<0.001). Altruism was the primary motivation for those willing to donate a kidney. The most important reason for refusal to donate was fear of adverse health consequences. Among the rural dwellers, never-married persons were more willing than the married to donate (P<0.05). Programs aimed at increasing awareness about the safety of kidney donation, reducing adverse beliefs about kidney donation, and encouraging altruistic tendencies will increase the availability of kidney donors.

The purpose of this study is to investigate the effects of the characteristics of the program, Open Your Eyes, an entertainment-education TV program in Korea, on parasocial interaction and behavioral intention for organ donation. The results indicated that affective evaluation positively affected parasocial interaction with the program but cognitive evaluation negatively affected involvement with beneficiaries in the program. Also, it was found that cognitive evaluation of Open Your Eyes had a significant positive effect on behavioral intention. In addition, a significant positive effect of program engagement on the behavioral intention was found. Thus, the results indicate that individuals who feel program engagement of Open Your Eyes will be more likely to proceed with organ donation. However, no direct effect of involvement with the beneficiary and program hosts was found.

A cost-effectiveness comparison of embryo donation with oocyte donation.
Finger, Reginald; Sommerfelt, Carol; Freeman, Melanie; Wilson, Carrie K; Wade, Amy; Daly, Douglas
2010-02-01
To compare the cost-effectiveness of embryo donation (ED) to that of oocyte donation (OD). Calculation of cost-effectiveness ratios (costs per outcome achieved) using data derived from clinical practices. In vitro fertilization centers and embryo donation programs. Infertile couples undergoing oocyte donation or embryo donation. Oocyte donation or embryo donation cycles. Cost-effectiveness ratios. For a single cycle, ED is approximately twice as cost-effective as OD, with a cost-effectiveness ratio of $21,990 per live delivery compared to 40,600 dollars. When strategies of up to three cycles (to achieve one live delivery) are used, ED costs 13,505 dollars per live delivery compared to 31,349 dollars for OD. Cost-effectiveness is a compelling reason for infertile couples to consider embryo donation. Copyright 2010 American Society for Reproductive Medicine. Published by Elsevier Inc. All rights reserved.

The purpose of this study was to test and validate a model to predict living and brain death organ donation intention in nursing students. The conceptual model was based on the theory planned behavior. Quota sampling methodology was used to recruit 921 nursing students from all over the country and data collection was done from October 1 to December 20, 2013. The model fit indices for the hypothetical model were suitable for the recommended level. Knowledge, attitude, subjective norm and perceived behavioral control explained 40.2% and 40.1% respectively for both living and brain death organ donation intention. Subjective norm was the most direct influential factor for organ donation intention. Knowledge had significant direct effect on attitude and indirect effect on subjective norm and perceived behavioral control. These effects were higher in brain death organ donation intention than in living donation intention. The overall findings of this study suggest the need to develop systematic education programs to increases knowledge about brain death organ donation. The development, application, and evaluation of intervention programs are required to improve subjective norm.
Paired kidney donations to expand the living donor pool.
Ferrari, Paolo; de Klerk, Marry
2009-01-01
The shortage of available deceased donors and the longer kidney transplant waiting lists in many countries around the world have placed greater emphasis on living donation (LD) as a means of meeting demand for transplantation in patients with end-stage kidney disease (ESKD). Increased LD rates are also driven by less invasive approaches to donor nephrectomy and by the excellent long-term results. LD kidney transplant outcomes are equivalent, if not superior, to those from deceased donors, even when donor and recipient are not genetically related, as is the case with spousal donations, the most frequent cohort of LD. Approximately 30% of willing and otherwise appropriate kidney donor/recipient pairs are biologically incompatible and do not proceed to live donor transplantation. In recent years, a number of strategies have been introduced to expand living donation programs beyond the classical direct donation, to overcome immunological barriers of blood group or HLA sensitization of recipients. New strategies in LD include paired kidney exchange (PKE), altruistic donation, altruistic donor chains and list exchange programs. Other alternative programs are desensitization and transplantation across the blood-type barrier. Regular PKE programs operate nationally in The Netherlands and the United Kingdom, or regionally in South Korea, Romania, the United States and Australia. If PKE were performed routinely using 2-way or 3-way PKE and altruistic donor chains, the rate of kidney transplants could increase by between 7% and 10%.

Governmental and private programs that pay next of kin who give permission for the removal of their deceased relative's organs for transplantation exist in a number of countries. Such payments, which may be given to the relatives or paid directly for funeral expenses or hospital bills unrelated to being a donor, aim to increase the rate of donation. The Declaration of Istanbul Custodian Group-in alignment with the World Health Organization Guiding Principles and the Council of Europe Convention Against Trafficking in Human Organs-has adopted a new policy statement opposing such practices. Payment programs are unwise because they produce a lower rate of donations than in countries with voluntary, unpaid programs; associate deceased donation with being poor and marginal in society; undermine public trust in the determination of death; and raise doubts about fair allocation of organs. Most important, allowing families to receive money for donation from a deceased person, who is at no risk of harm, will make it impossible to sustain prohibitions on paying living donors, who are at risk. Payment programs are also unethical. Tying coverage for funeral expenses or healthcare costs to a family allowing organs to be procured is exploitative, not "charitable." Using payment to overcome reluctance to donate based on cultural or religious beliefs especially offends principles of liberty and dignity. Finally, while it is appropriate to make donation "financially neutral"-by reimbursing the added medical costs of evaluating and maintaining a patient as a potential donor-such reimbursement may never be conditioned on a family agreeing to donate.

We solve the wave equation with variable wave speed on nonconforming domains with fourth order accuracy in both space and time. This is accomplished using an implicit finite difference (FD) scheme for the wave equation and solving an elliptic (modified Helmholtz) equation at each time step with fourth order spatial accuracy by the method of difference potentials (MDP). High-order MDP utilizes compact FD schemes on regular structured grids to efficiently solve problems on nonconforming domains while maintaining the design convergence rate of the underlying FD scheme. Asymptotically, the computational complexity of high-order MDP scales the same as that for FD.

Trypanosoma cruzi is a parasitic infection endemic in Central and Southern America, but is spreading into nonendemic countries with migration of infected individuals from endemic countries. The parasite is transmitted by transfusion or transplantation and donation screening is performed routinely in endemic countries to prevent transmission. In situations where migrants from endemic countries have settled in nonendemic countries and present as donors (blood or other cellular products), intervention is required to prevent transfusion or transplantation transmission. A screening program for T. cruzi was developed and has been used successfully for over 10 years that includes donor selection and donation screening. Donor selection criteria to identify specific risk of T. cruzi infection were developed together with laboratory screening of donations for T. cruzi antibodies and the subsequent confirmation of screen reactivity. Since the introduction of T. cruzi screening in England in 1998, a total of 38,585 donors and donations have been screened for T. cruzi antibodies, of which 223 were repeat reactive on screening and referred for confirmation: 206 confirmed negative, 14 inconclusive, and three positive. Since the move in 2005 from donor qualification to donation release testing, 15,536 donations were collected and screened, of which 15,499 (99.8%) were T. cruzi antibody negative and released to inventory. An effective program to minimize risk of the transmission of T. cruzi infection via donations has been developed and implemented. Not only does the program minimize risk of transmission, it also minimizes the cumulative, and needless, loss of donors and donations that would ensue if permanent donor deferral alone was adopted. © 2012 American Association of Blood Banks.

Human NOD2 Recognizes Structurally Unique Muramyl Dipeptides from Mycobacterium leprae.
Schenk, Mirjam; Mahapatra, Sebabrata; Le, Phuonganh; Kim, Hee Jin; Choi, Aaron W; Brennan, Patrick J; Belisle, John T; Modlin, Robert L

The innate immune system recognizes microbial pathogens via pattern recognition receptors. One such receptor, NOD2, via recognition of muramyl dipeptide (MDP), triggers a distinct network of innate immune responses, including the production of interleukin-32 (IL-32), which leads to the differentiation of monocytes into dendritic cells (DC). NOD2 has been implicated in the pathogenesis of human leprosy, yet it is not clear whether Mycobacterium leprae, which has a distinct MDP structure, can activate this pathway. We investigated the effect of MDP structure on the innate immune response, finding that infection of monocytes with M. leprae induces IL-32 and DC differentiation in a NOD2-dependent manner. The presence of the proximal l-Ala instead of Gly in the common configuration of the peptide side chain of M. leprae did not affect recognition by NOD2 or cytokine production. Furthermore, amidation of the d-Glu residue did not alter NOD2 activation. These data provide experimental evidence that NOD2 recognizes naturally occurring structural variants of MDP.

The impact of extended maceration (EM) was studied in Cabernet Sauvignon grapes sourced from a vineyard subjected to four regulated deficit irrigation (RDI) treatments: (I) 100% replenishment of crop evapotranspiration (100% ETc), (II) 70% ETc, (III) 25% ETc until véraison, followed by 100% ETc until harvest, and IV) 25% ETc. Each vineyard replicate was made into wine with two replicates designated as controls (10-day skin contact) and two as extended maceration (EM, 30-day skin contact). The mean degree of polymerization (mDP), size distribution, concentration, and composition of wine proanthocyanidins (PAs) and monomeric flavan-3-ols of 90 fractions were characterized by preparative and analytical HPLC techniques. The maceration length imparted a larger effect on most chemical parameters. The RDI treatment had no effect on the extraction patterns of anthocyanins, PAs, and/or on the origin of the PAs extracted into the wines. Conversely, EM led to anthocyanin losses and increased PA extraction during maceration, with ~73% of seed-derived PAs. Accordingly, the concentration of monomeric flavan-3-ols, oligomeric (2 ≤ mDP < 5) and polymeric PAs (mDP ≥ 5) was higher in EM wines. The size distribution of the wines' PAs revealed two major peaks as a function of concentration at mDP 2 (22-27% of total PAs mass) and at mDP 6-7 (12-17% of total PAs mass) and was found to follow a non-normal Rayleigh-type distribution.

Initial attachment of the cariogenic Streptococcus mutans onto dental enamel is largely promoted by the adsorption of specific salivary proteins on enamel surface. Some phosphorylated salivary proteins were found to reduce S. mutans adhesion by competitively inhibiting the adsorption of S. mutans-binding salivary glycoproteins to hydroxyapatite (HA). The aim of this study was to develop antiadherence compounds for preventing dental biofilm development. We synthesized phosphorylated polyethylene glycol (PEG) derivatives and examined the possibility of surface pretreatment with them for preventing S. mutans adhesion in vitro and dental biofilm formation in vivo. Pretreatment of the HA surface with methacryloyloxydecyl phosphate (MDP)-PEG prior to saliva incubation hydrophilized the surface and thereby reduced salivary protein adsorption and saliva-promoted bacterial attachment to HA. However, when MDP-PEG was added to the saliva-pretreated HA (S-HA) surface, its inhibitory effect on bacterial binding was completely diminished. S. mutans adhesion onto S-HA was successfully reduced by treatment of the surface with pyrophosphate (PP), which desorbs salivary components from S-HA. Treatment of S-HA surfaces with MDP-PEG plus PP completely inhibited saliva-promoted S. mutans adhesion even when followed by additional saliva treatment. Finally, mouthwash with MDP-PEG plus PP prevented de novo biofilm development after thorough teeth cleaning in humans compared to either water or PP alone. We conclude that MDP-PEG plus PP has the potential for use as an antiadherence agent that prevents dental biofilm development.

This study analyzed the viability of financing a voucher program for cocaine addicts in Spain through public and private donations. Of the 136 companies contacted, 52 (38%) provided donations. The difference between the benefits (15,670 Euro/ $20,371) and the costs (3734 Euro/ $4854) was 11,936 Euro/ $15,517. The type of reinforcer a company can offer, the size of the company, and the time elapsed before responding may be determining variables in a company's decision whether to collaborate.
Evolution of a Statewide Organ Donation, Recovery and Allocation Program: “A Louisiana Perspective”
Jacobbi, Louise M.; McBride, Virginia
1999-01-01
This article reviews the evolution, growth, and impact of a structured organ recovery program on transplantation in Louisiana and discusses the clinical, social, and financial factors that influence the acceptance of organ transplantation as a viable treatment option for organ failure which once led inexorably to death. The rising number of organ donations and the formulation of strategies to increase these numbers to meet the growing need are examined. Enactment and enforcement of state and federal legislation making organ donation and transplantation available and safer have led to advances in organ donation, procurement, informed consent, and organ preservation, a technology that makes the use of cadaveric organs possible and durable.

As organ donation rates remain unable to meet the needs of individuals waiting for transplants, it is necessary to identify reasons for this shortage and develop solutions to address it. The introduction of kidney paired donation (KPD) programs represents one such innovation that has become a valuable tool in donation systems around the world. Although KPD has been successful in increasing kidney donation and transplantation, there are lingering questions about its legality. Donation through KPD is done in exchange for-and with the expectation of-a reciprocal kidney donation and transplantation. It is this reciprocity that has caused concern about whether KPD complies with existing law. Organ donation systems around the world are almost universally structured to legally prohibit the commercial exchange of organs. Australia, Canada, and the United States have accomplished this goal by prohibiting the exchange of an organ for "valuable consideration," which is a legal term that has not historically been limited to monetary exchange. Whether or not KPD programs violate this legislative prohibition will depend on the specific legislative provision being considered, and the legal system and case law of the particular jurisdiction in question. This article compares the experiences of Australia, Canada, and the United States in determining the legality of KPD and highlights the need for legal clarity and flexibility as donation and transplantation systems continue to evolve.

Donation after cardiocirculatory death in Canada

These recommendations are the result of a national, multidisciplinary, year-long process to discuss whether and how to proceed with organ donation after cardiocirculatory death (DCD) in Canada. A national forum was held in February 2005 to discuss and develop recommendations on the principles, procedures and practice related to DCD, including ethical and legal considerations. At the forum's conclusion, a strong majority of participants supported proceeding with DCD programs in Canada. The forum also recognized the need to formulate and emphasize core values to guide the development of programs and protocols based on the medical, ethical and legal framework established at this meeting. Although end-of-life care should routinely include the opportunity to donate organs and tissues, the duty of care toward dying patients and their families remains the dominant priority of health care teams. The complexity and profound implications of death are recognized and should be respected, along with differing personal, ethnocultural and religious perspectives on death and donation. Decisions around withdrawal of life-sustaining therapies, management of the dying process and the determination of death by cardiocirculatory criteria should be separate from and independent of donation and transplant processes. The recommendations in this report are intended to guide individual programs, regional health authorities and jurisdictions in the development of DCD protocols. Programs will develop based on local leadership and advance planning that includes education and engagement of stakeholders, mechanisms to assure safety and quality and public information. We recommend that programs begin with controlled DCD within the intensive care unit where (after a consensual decision to withdraw life-sustaining therapy) death is anticipated, but has not yet occurred, and unhurried consent discussions can be held. Uncontrolled donation (where death has occurred after unanticipated cardiac arrest) should only be considered after a controlled DCD program is well established. Although we recommend that programs commence with kidney donation, regional transplant expertise may guide the inclusion of other organs. The impact of DCD, including pre-and post-mortem interventions, on donor family experiences, organ availability, graft function and recipient survival should be carefully documented and studied.

The roles of dominos and nonsimultaneous chains in kidney paired donation.
Gentry, S E; Montgomery, R A; Swihart, B J; Segev, D L
2009-06-01
Efforts to expand kidney paired donation have included matching nondirected donors (NDDs) to incompatible pairs. In domino paired donation (DPD), an NDD gives to the recipient of an incompatible pair, beginning a string of simultaneous transplants that ends with a living donor giving to a recipient on the deceased donor waitlist. Recently, nonsimultaneous extended altruistic donor (NEAD) chains were introduced. In a NEAD chain, the last donor of the string of transplants initiated by an NDD is reserved to donate at a later time. Our aim was to project the impact of each of these strategies over 2 years of operation for paired donation programs that also allocate a given number of NDDs. Each NDD facilitated an average of 1.99 transplants using DPD versus 1.90 transplants using NEAD chains (p = 0.3), or 1.0 transplants donating directly to the waitlist (p < 0.001). NEAD chains did not yield more transplants compared with simultaneous DPD. Both DPD and NEAD chains relax reciprocality requirements and rebalance the blood-type distribution of donors. Because traditional paired donation will leave many incompatible pairs unmatched, novel approaches like DPD and NEAD chains must be explored if paired donation programs are to help a greater number of people.

The South African National Blood Service collects more than 700,000 units of blood annually from a population in which 11.4% is infected with human immunodeficiency virus 1 (HIV-1). The prevalence of HIV-1 in blood donations increased to 0.26% (1:385) in 1998, indicating that a significant number of window-period infective units were entering the blood supply (risk 3.4/100,000). To determine whether the implementation of a new donor selection policy and educational program introduced in 1999 was associated with reductions in the incidence and prevalence of HIV-1 in blood donations and the reduced transmission risk. We compared the prevalence of HIV-1 in 880,534 blood donations collected from 1999 through 2000 with the 791,639 blood donations collected from 2001 through 2002. We estimated the incidence of HIV-1 in 93,378 (1999-2000) and 67,231 (2001-2002) first-time donations and the residual risk for all donations in 2001-2002 using the less-sensitive enzyme-linked immunoassay and incidence-window period model. All blood donors in the Inland region of the South African National Blood Service were analyzed. Donor clinics in high HIV prevalence areas were closed. Programs targeting repeat donors and youth were initiated and HIV risk behavior education programs were developed. Structured donor interviews and an enhanced donor self-exclusion questionnaire were institutionalized. The prevalence of HIV-1 in blood donations declined from 0.17% in 1999-2000 to 0.08% in 2001-2002 after the implementation of the new donor selection and education policy. The number of high-risk donations collected decreased from 2.6% to 1.7% (P<.001), and the likelihood of these donations being infected decreased from 4.8% to 3.25%. The likelihood of first-time donors being recently infected with HIV-1 decreased from 18% to 14% (P = .07) and respective incidence of high-risk donations collected decreased from 2.6% to 1.7%. Donations from the majority black population declined from 6.6% to 4.2% (P<.001). Analysis of HIV-1 incidence in 2001-2002 suggests a residual risk of collecting a window period infectious unit of 2.6/100,000. The implementation of enhanced education and selection policies in South Africa was associated with decreased prevalence of HIV-1 in blood donations.
Increasing organ donation via changes in the default choice or allocation rule
Li, Danyang; Hawley, Zackary; Schnier, Kurt
2013-01-01
This research utilizes a laboratory experiment to evaluate the effectiveness of alternative public policies targeted at increasing the rate of deceased donor organ donation. The experiment includes treatments across different default choices and organ allocation rules inspired by the donor registration systems applied in different countries. Our results indicate that the opt-out with priority rule system generates the largest increase in organ donation relative to an opt-in only program. However, sizeable gains are achievable using either a priority rule or opt-out program separately, with the opt-out rule generating approximately 80% of the benefits achieved under a priority rule program.

[Transplant cross-over, an attractive option].
Maddalena, Emanuela
2013-01-01
Kidney transplant from living donors is an excellent option for patients with end- stage renal disease: around the world approximately 10-20% of patients on waiting lists have intended living donors incompatible by blood type or for the presence of donor-specific antibodies. Current strategies to overcome these barriers are desensitization protocols and the recent option of the kidney exchange programs. In this work we describe the types of donor exchange programs, from the two-way Kidney Paired Donation, where two incompatible donor-recipient couples exchange donors, to complex chains of transplants where the altruistic donation of a kidney (Living Non-direct Donor, or non-specific donation) is associated to a Kidney Paired Exchange Program (Domino Kidney Paired Donation, NEAD chains). The thesis also discusses some related ethical topics that have become international matters of debate, as well as some important cultural and social arguments for and against the application of kidney exchanges in Italy.

Training on organ donation and transplantation is relevant for transplantation improvement. This study aimed at investigating the perceived benefits of Transplant Procurement Management training programs on professional competence development and career evolutions of health care workers in organ donation and transplantation. An online survey was developed in 5 languages (Spanish, English, Italian, French, and Portuguese) and its link was emailed to 6839 individuals. They were asked to forward it to other professionals in organ donation and transplantation. The link was also shared on Facebook and at relevant congresses. Two research questions on the perceived influence of specialized training programs were identified. A total of 1102 participants (16.1%) took the survey; 87% reported participating in Transplant Procurement Management training programs, of which 95% selected Transplant Procurement Management courses as the most influential training they had participated in. For research question one, 98% reported influence on knowledge (score 4.5 [out of 5]), 93% on technical (4.2) and communication skills (4.1), 89% on attitude toward organ donation and transplantation (4.1), 92% on motivation to work (4.2), 91% on desire to innovate (4.0), 87% and 79% on ability to change organ donation and trans plantation practices (3.9) and policies (3.5). For research question 2, main and interaction effects for position at the time of training and type of training were reported. Transplant Procurement Management training programs had positive perceived effects.

In France, oocyte donation program is still underdeveloped because of lack of donors and this situation entails an important wave of cross border medical tourism to different European countries mainly Spain and Greece. In 2011, the General inspection of social affairs report recommended to the biomedicine agency to promote spontaneous oocyte donation via different channels of information to develop this national program. The main objective of this study is to assess the knowledge of women after baby delivery about oocyte donation. The second objective is the identification of ways to assure better information and to promote oocyte donation. We conducted a prospective study with anonymous questionnaire distribution to women after delivery at obstetrics/gynecology department of the Regional University Hospital and Maternity-Children Unit "Victor-Pauchet" of Amiens, from December 2012 to January 2013. Two hundred and fifty-five questionnaires were distributed and 242 of them were analyzed (94.9%). About oocyte donation knowledge: 28% did not know it was possible, 45% did not know it was legal in France, 54% did not know who was concerned and 36% know that a treatment is necessary, 9% think that oocyte donation is paid and 10% it is non-anonymous. If 67% seems to be favorable to this initiative, only 35% could accept to realize it. About information efficiency, 88% think not to receive enough information, 64% would like to have more information. The health care professional wanted to give this information is an obstetrician (51%), a midwife (37%) and a nurse (12%). Oocyte donation program is misoriented due to a lack of information. Obstetricians and midwives have an important educational and informative role to support oocyte donation. Specific strategy of communication and valuable targeted information are needed to motivate potential donor and achieve the objectives of the program. Copyright © 2014 Elsevier Masson SAS.

Little is known about the effect of education programs on changing attitudes and behaviors of participants and their families toward deceased organ donation. The subjects of this randomized trial were Japanese nursing students who were not previously designated organ donors. They were randomly assigned to either the education program or information booklet group. The program comprised a lecture followed by group discussion and information booklet. The primary outcome was self-reported organ donor designation. Outcomes were assessed by questionnaire. Data of 203 (99.0%) students were analyzed. At study end, seven of 102 students (6.9%) of the program group and one of 101 students (1.0%) of the booklet group consented to donate organs (proportion ratio 6.93 [95% CI 0.87-55.32]). There were significant between-group differences in willingness to consent for donation (54.9% vs 39.6%; proportion ratio 1.39 [95% CI 1.03-1.87]), family discussion (31.4% vs 15.9%; 1.98 [1.16-3.38]), and organ donor designation of family members (11.8% vs 2.0%; 5.94 [1.36-25.88]). No group differences were found in willingness for organ donation by students and family members. Although there were no significant between-group differences in organ donor designation, the program seems to indirectly promote consent to organ donation by their families. © 2016 The Authors.

Donation coordinators play an important role in the success or failure of organ donation and transplant programs. Nevertheless, these professionals' perspectives and practices have hardly been explored, particularly in low- and middle-income countries. To examine donation coordinators' discourse on the organ donation process and the barriers they perceive. A critical qualitative study was carried out in Guadalajara, Mexico. Twelve donation coordinators from public and private hospitals participated. DATA GATHERING AND ANALYSIS: Data were gathered by using semistructured interviews and critical discourse analysis. Participants indicated that partial results have been achieved in deceased organ donation. Concomitantly, multiple obstacles have adversely affected the process and outcomes: at the structural level, the fragmentation of the health system and the scarcity of financial and material resources; at the relational level, nonegalitarian relationships between coordinators and hospital personnel; at the ideational level, the transplant domain and its specialists overshadow the donation domain and its coordinators. Negative images are associated with donation coordinators. Organ donation faces structural, relational, and ideational barriers; hence, complex interventions should be undertaken. Donation coordinators also should be recognized by the health system.

Racial/ethnic minorities are underrepresented in current biobanking programs. The current study utilized community-based participatory research to identify motivating factors and barriers that affect older African Americans’ willingness to donate biospecimens. The standardized phone survey was administered to 78 African Americans who are 55 years old or older and live in the metropolitan Detroit area to assess their overall willingness to donate biospecimens and what factors were associated with it. The majority of the participants were willing to donate biospecimens, along with their personal information, for medical research and indicated that they did donate biospecimens when they were asked. However, African Americans were rarely asked to participate in biobanking programs. Furthermore, African Americans were not as concerned with research exploitation or as mistrusting of medical researchers as previously thought by the medical researchers. Even if African Americans were concerned over potential research exploitation or mistrust of medical researchers, these concerns or mistrust did not translate into an actual unwillingness to participate in biobanking programs. Rather, transparency in medical research and biobanking programs was more important when predicting African Americans’ willingness to donate biospecimens for medical research. The findings suggest that underrepresentation of African Americans in current biobanking programs may not be due to their willingness/unwillingness to participate in such programs, but rather due to a failure of medical researchers to approach them. Additionally, researchers and clinicians should focus on increasing the transparency of medical research and biobanking programs rather than changing African Americans’ potential negative attitudes toward them.

Organ shortage is a major public health challenge for transplant programs globally. The sustenance of such programs as an effective therapy for end-stage organ failure (ESOF) requires an exploration of public awareness and willingness to donate organs. This is imperative, especially in developing countries where ESOF is highly prevalent. We studied the awareness and predictors of public attitude toward organ donation in Kano city in northern Nigeria. Using interviewer-administered questionnaires, we assessed the awareness and willingness to donate solid organs among 400 adults in the Kano metropolis. Three hundred and five of the 383 respondents (79.6%) reported that they had heard about organ donation. There was a significant variation of awareness by education and ethnicity (P <0.05). Most respondents, 303 (79.1%), were willing to donate an organ. Gender [adjusted odds ratio (AOR) = 2.13; 95% confidence interval (CI): 1.40-4.95], educational attainment (AOR = 2.55; 95% CI: 1.35-5.88), marital status (AOR = 4.5; 95% CI: 2.97-9.1), religion (AOR = 3.40; 95% CI: 1.43-8.10) and ethnicity (AOR = 2.36; 95% CI 1.04-5.35) were significant predictors of willingness to donate an organ. Preferred organ recipients were parents (48.9%), children (21.3%), spouses (14.6%) and other relatives (13.4%). Reasons for willingness to donate organs included religion (51.2%), moral obligation (21.4%) and compassion (11.9%), among others. However, there was widespread ignorance of religious precepts concerning organ donation. The high level of awareness and willingness to donate organs in this society could be further enhanced by intensive information, education and communication strategies providing clear messages on societal benefits, religious aspects and bioethical guidance regarding organ donation.

Time to donating blood plays a major role in a regular donor to becoming continues one. The aim of this study was to determine the effective factors on the interval between the blood donations. In a longitudinal study in 2008, 864 samples of first-time donors in Shahrekord Blood Transfusion Center, capital city of Chaharmahal and Bakhtiari Province, Iran were selected by a systematic sampling and were followed up for five years. Among these samples, a subset of 424 donors who had at least two successful blood donations were chosen for this study and the time intervals between their donations were measured as response variable. Sex, body weight, age, marital status, education, stay and job were recorded as independent variables. Data analysis was performed based on log-normal hazard model with gamma correlated frailty. In this model, the frailties are sum of two independent components assumed a gamma distribution. The analysis was done via Bayesian approach using Markov Chain Monte Carlo algorithm by OpenBUGS. Convergence was checked via Gelman-Rubin criteria using BOA program in R. Age, job and education were significant on chance to donate blood (P<0.05). The chances of blood donation for the higher-aged donors, clericals, workers, free job, students and educated donors were higher and in return, time intervals between their blood donations were shorter. Due to the significance effect of some variables in the log-normal correlated frailty model, it is necessary to plan educational and cultural program to encourage the people with longer inter-donation intervals to donate more frequently.

Donation after cardiac death (DCD) is one method of organ donation. Nationally, more than half of evaluated DCD donors do not yield transplantable organs. There is no algorithm for predicting which DCD donors will be appropriate for organ procurement. Donation after cardiac death program costs from an organ procurement organization (OPO) accounting for all evaluated donors have not been reported. Hospital, transportation, and supply costs of potential DCD donors evaluated at a single OPO from January 2009 to June 2016 were collected. Mean costs per donor and per organ were calculated. Cost of DCD donors that did not yield a transplantable organ were included in cost analyses resulting in total cost of the DCD program. Donation after cardiac death donor costs were compared with costs of in-hospital donation after brain death (DBD) donors. There were 289 organs transplanted from 264 DCD donors evaluated. Mean cost per DCD donor yielding transplantable organs was $9,306. However, 127 donors yielded no organs, at a mean cost of $8,794 per donor. The total cost of the DCD program was $32,020 per donor and $15,179 per organ. Mean cost for an in-hospital DBD donor was $33,546 and $9,478 per organ transplanted. Mean organ yield for DBD donors was 3.54 vs 2.21 for DCD donors (p < 0.0001), making the cost per DBD organ 63% of the cost of a DCD organ. Mean cost per DCD donor is comparable with DBD donors, however, individual cost of DCD organs increases by almost 40% when all costs of an entire DCD program are included. Published by Elsevier Inc.

This nationwide survey investigated the actual practices for supporting and confirming the decision-making involved in related living-organ donations in Japan, focusing on organ type and program size differences. Answers to a questionnaire survey were collected from 89 of the 126 (71%) kidney and 30 of the 35 (86%) liver transplantation programs in Japan that were involved in living-donor transplantations in 2013. In 70% of the kidney and 90% of the liver transplantation programs, all donors underwent "third-party" interviews to confirm their voluntariness. The most common third parties were psychiatrists (90% and 83%, respectively). Many programs engaged in practices to support decision-making by donor candidates, including guaranteeing the right to withdraw consent to donate (70% and 100%, respectively) and prescribing a set "cooling-off period" (88% and 100%, respectively). Most donors were offered care by mental health specialists (86% and 93%, respectively). Third parties were designated by more of the larger kidney transplant programs compared with the smaller programs. In conclusion, the actual practices supporting and confirming the decision to donate a living organ varied depending on the organ concerned and the number of patients in the program. © Copyright 2015 The American Society of Transplantation and the American Society of Transplant Surgeons.

Objectives: To assess prevailing food patterns, and its association with physical activity and fitness among Spanish older adults. Methods: Cross-sectional study in Spain, collecting data from a sample ( n = 380; 54% female) aged 55-80 years (men) and 60-80 years (women) with no previously documented cardiovascular disease. Body weight, body fat and waist circumference were assessed. Physical activity performed was measured using the Minnesota Leisure-time Physical Activity Questionnaire (LTPA). Physical fitness was assessed using a validated physical fitness test battery. Food consumption was assessed by a validated semi-quantitative food-frequency questionnaire. Factor analysis identified two major dietary food patterns: "Western" (WDP) and "Mediterranean" (MDP) dietary patterns. Results: Participants in MDP's fourth quartile were classified in the second (men) and third (men and women) tertile of LTPA. After adjusting for age, body fat, waist-to-height ratio, and METs, in both sexes, a negative significant association was found between 30-s Chair stand and 6-min walking test, a positive significant association was found between 30-m Gait speed and 8-foot Time Up-and-Go (except in men) tests with WDP. The 30-m Gait speed test was negatively associated with MDP in men. Conclusions: MDP is associated with more time spent on LTPA, and this association was independent of body composition and a fast gait speed in men. WDP is associated with slower gait speed and lower body strength, agility and aerobic endurance. MDP has protective effect on healthy physical fitness, and WDP may be a contributor to frailty.

The bone metastasis appeared early before the bone imaging for most of the above patients. (99)Tc(m)-MDP ((99)Tc(m) marked methylene diphosphonate) bone imaging could diagnosis the bone metastasis with highly sensitivity, but with lower specificity. The aim of this study is to explore the diagnostic value of (99)Tc(m)-MDP SPECT/CT combined SPECT/MRI Multi modality imaging for the early period atypical bone metastases. 15 to 30 mCi (99)Tc(m)-MDP was intravenously injected to the 34 malignant patients diagnosed as doubtful early bone metastases. SPECT, CT and SPECT/CT images were captured and analyzed consequently. For the patients diagnosed as early period atypical bone metastases by SPECT/CT, combining the SPECT/CT and MRI together as the SPECT/MRI integrated image. The obtained SPECT/MRI image was analyzed and compared with the pathogenic results of patients. The results indicated that 34 early period doubtful metastatic focus, including 34 SPECT positive focus, 17 focus without special changes by using CT method, 11 bone metastases focus by using SPECT/CT method, 23 doubtful bone metastases focus, 8 doubtful bone metastases focus, 14 doubtful bone metastases focus and 2 focus without clear image. Totally, SPECT/CT combined with SPECT/MRI method diagnosed 30 bone metastatic focus and 4 doubtfully metastatic focus. In conclusion, (99)Tc(m)-MDP SPECT/CT combined SPECT/MRI Multi modality imaging shows a higher diagnostic value for the early period bone metastases, which also enhances the diagnostic accuracy rate.

Our aim was to observe if patients with panic disorder (PD) and patients with major depression with panic attacks (MDP) (Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria) respond in a similar way to the induction of panic attacks by an oral caffeine challenge test. We randomly selected 29 patients with PD, 27 with MDP, 25 with major depression without panic attacks (MD), and 28 healthy volunteers. The patients had no psychotropic drug for at least a 4-week period. In a randomized double-blind experiment performed in 2 occasions 7 days apart, 480 mg caffeine and a caffeine-free (placebo) solution were administered in a coffee form and anxiety scales were applied before and after each test. A total of 58.6% (n = 17) of patients with PD, 44.4% (n = 12) of patients with MDP, 12.0% (n = 3) of patients with MD, and 7.1% (n= 2) of control subjects had a panic attack after the 480-mg caffeine challenge test (chi(2)(3) = 16.22, P = .001). The patients with PD and MDP were more sensitive to caffeine than were patients with MD and healthy volunteers. No panic attack was observed after the caffeine-free solution intake. The patients with MD had a lower heart rate response to the test than all the other groups (2-way analysis of variance, group by time interaction with Greenhouse-Geisser correction: F(3,762) = 2.85, P = .026). Our data suggest that there is an association between panic attacks, no matter if associated with PD or MDP, and hyperreactivity to an oral caffeine challenge test.

Organ transplantation is the most successful treatment for some forms of organ failure, yet a lack of organs means many die on the waiting list. In the United Kingdom, the Organ Donation Taskforce was set up to identify barriers to organ donation and in 2008 released its first report (Organ Donation Taskforce Report; ODTR). This study assesses the success since the ODTR and examines the impact of the United Kingdom's controlled donation after circulatory death (DCD) program and the controversies surrounding it. There were 12 864 intended donation after brain death (DBD) or DCD donors from April 2004 to March 2014. When the 5 years preceding the ODTR was compared to the 5 years following, intended DCD donors increased 292% (1187 to 4652), and intended DBD donors increased 11% (3327 to 3698). Organs retrieved per intended DBD donor remained static (3.30 to 3.26), whereas there was a decrease in DCD (1.54 to 0.99) due to a large rise in donors who did not proceed to donation (325 to 2464). The majority of DCD donors who proceeded did so within 30 min from time of withdrawal. Our study suggests further work on converting eligible referrals to organ donation and exploring methods of converting DCD to DBD donors. © 2017 The American Society of Transplantation and the American Society of Transplant Surgeons.

[Renal excretion of methylene-diphosphate-technium-99m. Preliminary observations].
Vattimo, A; Martini, G
1983-11-30
The purpose of this study is to elucidate the mechanism of the renal excretion of 99mTc-MDP in man. We compared the renal clearance of 99mTc-MDP and 51Cr-EDTA (glomerular filtration rate agent). Since the 99mTc-MDP is bound to the plasma protein, the free fraction was calculated by dialysis. The clearances were obtained by single-injection technique. The plasma disappearance of the tracers was resolved into three exponential functions and area was calculated. The clearance was calculated by dividing the amount of the tracers excreted during the first four hours and the plasma area. In this study no difference was found in the clearance of the two agents. These findings suggest that the renal excretion of diphosphonate is related to the glomerular filtration rate.
Regulated compensation for kidney donors in the Philippines.
Padilla, Benita S
2009-04-01
The purpose of this review is to discuss the recent events and experiences in the Philippines related to compensated kidney donation. Between 2002 and 2008, the Philippine government, through the Department of Health, administered a program called the Philippine Organ Donation Program that allowed prospective kidney providers to sign up, be allocated to prospective recipients and receive gratuities for their kidney. Transplant tourism flourished during this period because of rampant disregard for the regulation limiting foreign recipients to 10% of total kidney transplants. There is evidence of inadequate donor care. Efforts to curb the problem included a ban on foreigners coming to the Philippines to have kidney transplants with Filipinos as donors as well as strengthening of the implementing rules and regulations of both the antihuman trafficking law and the organ donation law that allowed donation after brain death. The experience in the Philippines mirrored those in India and Pakistan where paid donors reported poor outcomes. An effective national kidney disease prevention program and the deceased donor program for transplantation should be aggressively promoted. Legislation against transplant commercialism is needed.

In modern operating rooms, clean and unused medical supplies are routinely discarded and can be effectively recovered and redistributed abroad to alleviate the environmental burden of donor hospitals and to generate substantial health benefits at resource-poor recipient institutions. We established a recovery and donation program to collect clean and unused supplies for healthcare institutions in developing nations. We analyzed items donated over a 3-year period (September 2010-November 2013) by quantity and weight, and estimated the projected value of the program under potential nationwide participation. To capture the health benefits attributable to the donated supplies at recipient institutions, we partnered with two tertiary-care centers in Guayaquil, Ecuador and conducted a pilot study on the utility of the donated supplies at the recipient institutions (October 2013). We determined the disability-adjusted life years (DALY) averted for all patients undergoing procedures involving donated items and estimated the annual attributable DALY as well as the cost per DALY averted both by supply and by procedure. Approximately, 2 million lbs (907,185 kg) per year of medical supplies are recoverable from large non-rural US academic medical centers. Of these supplies, 19 common categories represent a potential for donation worth US $15 million per year, at a cost-utility of US $2.14 per DALY averted. Hospital operating rooms continue to represent a large source of recoverable surgical supplies that have demonstrable health benefits in the recipient communities. Cost-effective recovery and need-based donation programs can significantly alleviate the global burden of surgical diseases.

An academic-based hospital donor site: do physicians donate blood?
Kanner, William A; Jeffus, Susanne; Wehrli, Gay
2009-01-01
The objectives of this prospective, cross-sectional study were to characterize blood donors in an academic-based hospital donor center, to determine whether physicians donate, and to elucidate the donation impetus. A confidential survey was issued to presenting, potential donors over 200 weekdays. Three questions were asked: their role at the institution, if and when they had previously donated blood, and what prompted the current donation. The majority of the 687 respondents were institution-affiliated (73.5%) and 79.3% had previously donated, with a median of 3 mo since the prior donation. Only 21 (3.1%) respondents were physicians. The predominant reasons for donor presentation were an appointment, knowing it had been 8 wk since the last donation, and contact by the blood center to donate. This study shows the dearth of physician blood donors and a strong cohort of institution-affiliated repeat donors. Physicians represent a potential, stable, and sustainable donor pool; further studies are needed to establish physician recruitment programs.
SU-D-BRB-05: Quantum Learning for Knowledge-Based Response-Adaptive Radiotherapy
DOE Office of Scientific and Technical Information (OSTI.GOV)
El Naqa, I; Ten, R
Purpose: There is tremendous excitement in radiotherapy about applying data-driven methods to develop personalized clinical decisions for real-time response-based adaptation. However, classical statistical learning methods lack in terms of efficiency and ability to predict outcomes under conditions of uncertainty and incomplete information. Therefore, we are investigating physics-inspired machine learning approaches by utilizing quantum principles for developing a robust framework to dynamically adapt treatments to individual patient’s characteristics and optimize outcomes. Methods: We studied 88 liver SBRT patients with 35 on non-adaptive and 53 on adaptive protocols. Adaptation was based on liver function using a split-course of 3+2 fractions with amore » month break. The radiotherapy environment was modeled as a Markov decision process (MDP) of baseline and one month into treatment states. The patient environment was modeled by a 5-variable state represented by patient’s clinical and dosimetric covariates. For comparison of classical and quantum learning methods, decision-making to adapt at one month was considered. The MDP objective was defined by the complication-free tumor control (P{sup +}=TCPx(1-NTCP)). A simple regression model represented state-action mapping. Single bit in classical MDP and a qubit of 2-superimposed states in quantum MDP represented the decision actions. Classical decision selection was done using reinforcement Q-learning and quantum searching was performed using Grover’s algorithm, which applies uniform superposition over possible states and yields quadratic speed-up. Results: Classical/quantum MDPs suggested adaptation (probability amplitude ≥0.5) 79% of the time for splitcourses and 100% for continuous-courses. However, the classical MDP had an average adaptation probability of 0.5±0.22 while the quantum algorithm reached 0.76±0.28. In cases where adaptation failed, classical MDP yielded 0.31±0.26 average amplitude while the quantum approach averaged a more optimistic 0.57±0.4, but with high phase fluctuations. Conclusion: Our results demonstrate that quantum machine learning approaches provide a feasible and promising framework for real-time and sequential clinical decision-making in adaptive radiotherapy.« less

Self-assembled nanolayering structures have been reported in resin-dentin interfaces created by adhesives that contain 10-methacryloyloxydecyl dihydrogen phosphate (10-MDP). These structures have been hypothesized to contribute to bond durability. The objective of the present study was to determine the extent of nanolayering in resin-dentin interfaces after application of commercialized 10-MDP-containing self-etch and universal adhesives to human dentin. Seven commercialized adhesives were examined: Adhese Universal (Ivoclar-Vivadent), All-Bond Universal (Bisco, Inc.), Clearfil SE Bond 2, Clearfil S3 Bond Plus, Clearfil Universal Bond (all from Kuraray Noritake Dental Inc.), G-Premio Bond (GC Corp.), and Scotchbond Universal (3M ESPE). Each adhesive was applied in the self-etch mode on midcoronal dentin according to the respective manufacturer’s instructions. Bonded specimens (n = 6) were covered with flowable resin composite, processed for transmission electron microscopy, and examined at 30 random sites without staining. Thin-film glancing angle X-ray diffraction (XRD) was used to detect the characteristic peaks exhibited by nanolayering (n = 4). The control consisted of 15%wt, 10%wt, and 5%wt 10-MDP (DM Healthcare Products, Inc.) dissolved in a mixed solvent (ethanol and water weight ratio 9:8, with photoinitiators). Experimental primers were applied to dentin for 20 s, covered with hydrophobic resin layer, and examined in the same manner. Profuse nanolayering with highly ordered periodicity (~3.7 nm wide) was observed adjacent to partially dissolved apatite crystallites in dentin treated with the 15% 10-MDP primer. Three peaks in the 2θ range of 2.40° (3.68 nm), 4.78° (1.85 nm), and 7.18° (1.23 nm) were identified from thin-film XRD. Reduction in the extent of nanolayering was observed in the 10% and 5% 10-MDP experimental primer-dentin interface along with lower intensity XRD peaks. Nanolayering and characteristic XRD peaks were rarely observed in specimens prepared from the commercialized adhesives. The sparsity of nanolayering in resin-dentin interfaces created by commercialized adhesives challenges its clinical effectiveness as a mechanism for improving bond longevity in dentin bonding.

The purpose of this survey was to determine how Canadian healthcare professionals perceive their deficiencies and educational requirements related to organ and tissue donation. We surveyed 641 intensive care unit (ICU) physicians, 1,349 ICU nurses, 1,561 emergency room (ER) physicians, and 1,873 ER nurses. The survey was distributed by the national organization for each profession (the Canadian Association of Emergency Physicians, the Canadian Association of Critical Care Nurses, and the National Emergency Nurses Association). Canadian Blood Services developed the critical care physician list in collaboration with the Canadian Critical Care Society. Survey development included questions related to comfort with, and knowledge of, key competencies in organ and tissue donation. Eight hundred thirty-one (15.3%) of a possible 5,424 respondents participated in the survey. Over 50% of respondents rated the following topics as highly important: knowledge of general organ and tissue donation, neurological determination of death, donation after cardiac death, and medical-legal donation issues. High competency comfort levels ranged from 14.7-50.9% for ICU nurses and 8.0-34.6% for ER nurses. Competency comfort levels were higher for ICU physicians (67.5-85.6%) than for ER physicians who rated all competencies lower. Respondents identified a need for a curriculum on national organ donation and preferred e-learning as the method of education. Both ICU nurses and ER practitioners expressed low comfort levels with their competencies regarding organ donation. Intensive care unit physicians had a much higher level of comfort; however, the majority of these respondents were specialty trained and working in academic centres with active donation and transplant programs. A national organ donation curriculum is needed.
Ethical Issues in Live-Donor Reimbursement Program.
Voo, T C; Koh, S; Campbell, A V
2016-04-01
Reimbursement of expenses and costs incurred by live organ donation is permitted in many countries to encourage donation and to protect the welfare of live donors. Potential ethical issues may arise with reimbursement programs and their implementation, which vary across countries. This paper discusses some ethical issues with live donor reimbursement to stimulate discussion on how to ethically enhance its implementation to improve outcomes for both donors and recipients. In addition, we will consider whether reimbursement should be supplemented with compensation for nonfinancial losses, such as pain and suffering, to encourage live donation.

To provide the appropriately diverse blood supply necessary to support alloimmunized and chronically transfused patients, minority donation recruitment programs have been implemented. This study investigated temporal changes in minority red blood cell (RBC) donation patterns in the United States. Data on donor race and ethnicity from 2006 through 2015, including the number of unique donors, collections, RBCs successfully donated, and average annual number of RBC donations per donor (donor fraction), were collected from eight US blood collectors. Minority donors were stratified into the following groups: Asian, black or African American, Hispanic or Latino, Native Indian or Alaska Native, Native Hawaiian or other Pacific Islander, white, multiracial/other, and no answer/not sure. Over the 10-year period, white donors annually constituted the majority of unique donors (range, 70.7%-73.9%), had the greatest proportion of collections (range, 76.1%-79.8%), and donated the greatest proportion of RBC units (range, 76.3%-80.2%). These donors also had the highest annual donor fraction (range, 1.82-1.91 units per donor). Black or African American donors annually constituted between 4.9 and 5.2% of all donors during the study period and donated between 4.0 and 4.3% of all RBC units. Linear regression analysis revealed decreasing numbers of donors, collections, and donated RBC units from white donors over time. Although the US population has diversified, and minority recruitment programs have been implemented, white donors constitute the majority of RBC donors and donations. Focused and effective efforts are needed to increase the proportion of minority donors. © 2017 AABB.

To our knowledge, no study has yet assessed the association between dietary patterns and incidence of eating disorders. This study aimed to assess the association between adherence to the Mediterranean dietary pattern (MDP) and incident risk of anorexia (AN) and bulimia nervosa (BN). We conducted a prospective cohort study of 11 800 women from the Seguimiento Universidad de Navarra follow-up project. Participants were classified as having incident AN or BN if they were free of AN or BN at baseline and reported a physician-made diagnosis of AN or BN during the follow-up period. Nutritional status, lifestyle, and behavioral variables were investigated and used as covariates. A validated 136-item food frequency questionnaire and the Trichopoulou score were used to assess adherence to the MDP. After a median follow-up time of 9.4 y, 100 new cases of AN and BN were identified. The multivariate hazard ratio of AN and BN for the two upper categories of adherence to the MDP were 0.39 (95% CI: 0.20-0.75) and 0.32 (95% CI: 0.14-0.70; P trend = 0.021). Inverse dose-response relationships were found for the consumption of cereals and olive oil and marginally for polyunsaturated fatty acid intake. To address reverse causation, multivariable linear regressions were run using a cross-sectional approach between adherence to the MDP and risk of AN and BN at baseline. No difference in adherence was found between participants with and without eating disorders. Our results suggest a potential inverse association between the MDP and the risk of AN and BN. Additional longitudinal studies and trials are needed. Copyright © 2018 Elsevier Inc. All rights reserved.

A novel microdialysis-dissolution/permeation (M-D/P) system was developed for the biopharmaceutical assessment of oral drug formulations. This system consists of a side-by-side diffusion chamber, a microdialysis unit fixed within the dissolution chamber for continuous sampling, and a biomimetic Permeapad® as the intestinal barrier. In the M-D/P system, the concentration of the molecularly dissolved drug (with MWCO <20kDa) was measured over time in the dissolution compartment (representing the gastrointestinal tract) while the concentration of the permeated drug was measured in the acceptor compartment (representing the blood). The kinetics of both the dissolution process and the permeation process were simultaneously quantified under circumstances that mimic physiological conditions. For the current proof-of-concept study, hydrocortisone (HCS) in the form of slowly dissolving solvate crystals and buffer and the biorelevant fasted state simulated intestinal fluids (FaSSIF), were employed as the model drug and dissolution media, respectively. The applicability of the M-D/P system to dissolution and permeation profiling of HCS in buffer and in FaSSIF has been successfully demonstrated. Compared to the conventional direct sampling method (using filter of 0.1-0.45μm), sampling by the M-D/P system exhibited distinct advantages, including (1) showing minimal disturbance of the permeation process, (2) differentiating "molecularly" dissolved drugs from "apparently" dissolved drugs during dissolution of HCS in FaSSIF, and (3) being less laborious and having better sampling temporal resolution. M-D/P system appeared to be a promising, simple and routine tool that allows for the researchers' intensive comprehension of the interplay of dissolution and permeation thus helping for better oral formulation screening and as an ultimate goal, for better dosage forms assessment.

The aims of this study were to determine the existence of migratory movements and to identify ecological stocks of the silverside Odontesthes smitti along its distribution in the Southern Atlantic Ocean, using metazoan parasites as biological tags. Samples were obtained from San José Gulf (SJ) (42° 25' S; 64° 07' W) and Nuevo Gulf (NG) (42° 47' S; 65° 02' W) in north Patagonia during winter and summer and in waters off Mar del Plata (MDP) (38° 03' S; 57° 32' W), Bonaerense region, during winter. Fifteen parasite species were collected. Multivariate statistical procedures on parasite community data showed strong effect of host size on the structure of parasite assemblages. Taking into account the variations among samples due to host size, the differential structure of parasite communities between SJ and NG suggests that fish inhabiting these localities could belong to different ecological stocks. Fish from MDP and SJ caught in summer showed similar composition in their parasite assemblages, which is congruent with a migratory cycle that implies that fish caught in MDP during winter inhabit SJ during summer. Further evidence of the Patagonian origin of MDP O. smitti is the presence of the digenean Proctotrema bartolii in fish from both regions. Proctotrema bartolii is acquired by O. smitti only in the Magellanic province, where its intermediate host, Darina solenoides, is distributed. The analyses suggest that O. smitti inhabiting north Patagonian gulfs could belong to different ecological stocks and that O. smitti caught in MDP could have come from SJ. © 2011 The Authors.

The relationship between dendritic cells (DCs) and macrophages is often debated. Here we ask whether steady-state, lymphoid-tissue-resident conventional DCs (cDCs), plasmacytoid DCs (pDCs), and macrophages share a common macrophage-DC-restricted precursor (MDP). Using new clonal culture assays combined with adoptive transfer, we found that MDP fractions isolated by previous strategies are dominated by precursors of macrophages and monocytes, include some multipotent precursors of other hematopoietic lineages, but contain few precursors of resident cDCs and pDCs and no detectable common precursors restricted to these DC types and macrophages. Overall we find no evidence for a common restricted MDP leading to both macrophages and FL-dependent, resident cDCs and pDCs. Copyright © 2014 Elsevier Inc. All rights reserved.

College students form a large and important group of population eligible for blood donation. Studies report that students do not donate much, and medical students' blood donation rate is less as compared to non-medical students. To assess and compare the knowledge, attitude, and practice of blood donation among medical and non-medical Nepalese students. A cross-sectional descriptive study using structured self-administered questionnaire was conducted in students of medical (MBBS) and non-medical programs of different colleges of Nepal. Total 456 students, 177 non-medical and 279 medical, participated; 28.5% students were donors. More medical students donated blood, more often, and were more knowledgeable in all aspects of blood and blood donation related knowledge (p values 0.01 or less). In both groups, proportionately more boys donated than girls. Common reasons for not donating included no request, medically unfit, no information about blood collection services, fear of weakness, and fear related to venepuncture. Moral satisfaction was the commonest reason to donate. Among Nepalese students, medical students donate more and are more knowledgeable than non-medical students. Lack of information and lack of direct requests are important causes of fewer donors in the non-medical group and girls.

Minority donation in the United States: challenges and needs.
Shaz, Beth H; Hillyer, Christopher D
2010-11-01
In the United States, blood donation rates of African-Americans are 25-50% of that of white individuals. As African-Americans make up an ever increasing and now substantial minority, and African-American recipients of blood transfusion, both specialized, such as sickle cell disease patients, and general hospitalized patients, have a better chance of receiving phenotype-matched or appropriate red blood cell units when there is a significant percentage of products in the inventory from African-American donors, it is important to understand the reason for the observed difference. Possible reasons for this discrepancy in donation rates include increased rates of donor deferral and ineligibility; increased barriers to donation, such as fear and distrust; and different marketing and education strategies. Thus, to increase the blood availability to African-American recipients, the reasons for these donation rate differences must be better understood and subsequently addressed through improved blood donor recruitment programs. The majority of African-American donor recruitment programs have focused on donating for sickle cell disease patients, particularly children, which have been of limited success. Significant improvements in African-American donor recruitment are needed to adequately meet the demand of African-American patients as well as the entire population.
Identification of Structural Features of Condensed Tannins That Affect Protein Aggregation

2017-01-01
A diverse panel of condensed tannins was used to resolve the confounding effects of size and subunit composition seen previously in tannin-protein interactions. Turbidimetry revealed that size in terms of mean degree of polymerisation (mDP) or average molecular weight (amw) was the most important tannin parameter. The smallest tannin with the relatively largest effect on protein aggregation had an mDP of ~7. The average size was significantly correlated with aggregation of bovine serum albumin, BSA (mDP: r = -0.916; amw: r = -0.925; p<0.01; df = 27), and gelatin (mDP: r = -0.961; amw: r = -0.981; p<0.01; df = 12). The procyanidin/prodelphinidin and cis-/trans-flavan-3-ol ratios gave no significant correlations. Tryptophan fluorescence quenching indicated that procyanidins and cis-flavan-3-ol units contributed most to the tannin interactions on the BSA surface and in the hydrophobic binding pocket (r = 0.677; p<0.05; df = 9 and r = 0.887; p<0.01; df = 9, respectively). Circular dichroism revealed that higher proportions of prodelphinidins decreased the apparent α-helix content (r = -0.941; p<0.01; df = 5) and increased the apparent β-sheet content (r = 0.916; p<0.05; df = 5) of BSA.

Discovery of cancer common and specific driver gene sets
2017-01-01
Abstract Cancer is known as a disease mainly caused by gene alterations. Discovery of mutated driver pathways or gene sets is becoming an important step to understand molecular mechanisms of carcinogenesis. However, systematically investigating commonalities and specificities of driver gene sets among multiple cancer types is still a great challenge, but this investigation will undoubtedly benefit deciphering cancers and will be helpful for personalized therapy and precision medicine in cancer treatment. In this study, we propose two optimization models to de novo discover common driver gene sets among multiple cancer types (ComMDP) and specific driver gene sets of one certain or multiple cancer types to other cancers (SpeMDP), respectively. We first apply ComMDP and SpeMDP to simulated data to validate their efficiency. Then, we further apply these methods to 12 cancer types from The Cancer Genome Atlas (TCGA) and obtain several biologically meaningful driver pathways. As examples, we construct a common cancer pathway model for BRCA and OV, infer a complex driver pathway model for BRCA carcinogenesis based on common driver gene sets of BRCA with eight cancer types, and investigate specific driver pathways of the liquid cancer lymphoblastic acute myeloid leukemia (LAML) versus other solid cancer types. In these processes more candidate cancer genes are also found. PMID:28168295

The aim of this work was to demonstrate an immunostimulatory and adjuvant effect of new apyrogenic lipophilic derivatives of norAbuMDP and norAbuGMDP formulated in nanoliposomes. Nanoliposomes and metallochelating nanoliposomes were prepared by lipid film hydration and extrusion methods. The structure of the liposomal formulation was studied by electron microscopy, AF microscopy, and dynamic light scattering. Sublethal and lethal γ-irradiation mice models were used to demonstrate stimulation of innate immune system. Recombinant Hsp90 antigen (Candida albicans) bound onto metallochelating nanoliposomes was used for immunisation of mice to demonstrate adjuvant activities of tested compounds. Safety and stimulation of innate and adaptive immunity were demonstrated on rabbits and mice. The liposomal formulation of norAbuMDP/GMDP was apyrogenic in rabbit test and lacking any side effect in vivo. Recovery of bone marrow after sublethal γ-irradiation as well as increased survival of mice after lethal irradiation was demonstrated. Enhancement of specific immune response was demonstrated for some derivatives incorporated in metallochelating nanoliposomes with recombinant Hsp90 protein antigen. Liposomal formulations of new lipophilic derivatives of norAbuMDP/GMDP proved themselves as promising adjuvants for recombinant vaccines as well as immunomodulators for stimulation of innate immunity and bone-marrow recovery after chemo/radio therapy of cancer.

Professional education and hospital development for organ donation.
Fukushima, N; Konaka, S; Kato, O; Ashikari, J
2012-05-01
Because of the strict Organ Transplantation Act, only 81 brain dead (BD) organ donations had been performed in Japan for 13 years since 1997. The Act was revised on July 17, 2010, allowing, organs to be donated after BD with consent from the family, if the subject had not denied organ donation previously. This act has lead to an expectation of a 6-7-fold increase in BD donation. The 82 organ procurement coordinators (OPC) in Japan include 32 belonging to the Japanese Organ Network (JOT) and the others to each administrative division. JOT has guideline manuals of standard roles and procedures of OPC during organ procurement from BD and cardiac death donors. To manage the increased organ donations after the revision of the act, we have modified the education system. First, we modified the guideline manuals for OPC to correspond to the revised Transplant Act and governmental guidelines. Second, all OPC gathered in a meeting room to learn the new organ procurement system to deal with the revised Transplant Act and guidelines. Third, a special education program for 2 months was provided for the 10 newcomers. Last, the practical training in each donor case for newcomers was performed by older OPC. Topics of the education program were the revised transplant act and guidelines, family approach to organ donation, BD diagnosis, donor evaluation and management, organ procurement and preservation, allocation system, hospital development and family care. In the future, each OPC will be divided into special categories, such as the donor family OPC, the donor management OPC, and the operating room OPC. Therefore, we need to construct separate special education programs for each category. Copyright © 2012 Elsevier Inc. All rights reserved.

Background. Blood donation is remarkably safe medical procedure. However, attitudes, beliefs, and level of knowledge may affect it. Objectives. To measure the level of knowledge regarding blood donation, find out positive and negative attitudes, identify the obstacles, and suggest some motivational factors. Methodology. A cross-sectional study was conducted at King Abdulaziz Medical City (KAMC). Participants were selected by convenient nonrandom sampling technique. A self-created questionnaire was used for data collection. Results. The study included 349 individuals. About 45.8% of the participants claimed that they have a history of blood donation. Reported causes for not donating blood were blood donation not crossing their mind (52.4%), no time for donation (45%), and difficulty in accessing blood donation center (41.3%). Reported motivating factors for donating blood were one day off (81.4%), mobile blood donation caravans in public areas (79.1%), token gifts (31.5%), and finally paying money (18.9%). Conclusion. People in the age group 31-50 years, males, higher education and military were more likely to donate blood as well as People who showed higher knowledge level and positive attitude towards blood donation. More educational programs to increase the awareness in specific targeted populations and also to focus on some motivational factors are recommended.

The rate of organ donation by older potential donors is significantly declining even though recent studies show positive clinical outcomes with organs transplanted from older donors. This study examined the 50+ age demographic to identify the rationale for donation decisions, preferred media methods of donation information delivery, and responsiveness to an age-tailored donation message. Results from 579 surveys, 87% from the 50+ age demographic, found respondents prone to self-select themselves as medically ineligible based on current medication and health status, even though they might be medically suitable donors. Their incentive to pursue additional information on donation is limited except when motivated by personal accounts within their families and communities. In addition, even when computer literate, they continue to favor the printed or spoken word for donation information delivery. The results suggest an opportunity for those working with older adults to develop more personalized, localized donation education programs targeting this age demographic. © The Author(s) 2014.

The Conscious Body Donation Program conducted since 2003 by the Department of Human Anatomy, Medical University of Silesia in Katowice was the first innovative project aimed at obtaining informed donors' bodies for the purpose of teaching anatomy in Poland. The aim of this prospective study was to determine the declared donors' characteristics and to establish the possible motivation for body donation. A total of 244 application files were reviewed and the following information was analyzed: donor's age, age at which the decision to donate the body was made, donor's place of residence and declared nationality, family background, education and profession, family structure and religion. Our results showed that mainly elderly people decided to donate their bodies (68.5 ± 11.84 years), living mostly in large and medium-sized cities. Men--donors often lived in small towns. Most of the donors were of blue-collar parentage, completed secondary education and at the time of taking decision to donate where married and retired. Widows were more likely to make the decision to donate than widowers. Most of our donors were Catholic. Our analysis of the profile of Polish donors may be useful to understand better for which groups of people death is not to be perceived as the end, and may become a value, which can be beneficial to living people.
Brain donation for schizophrenia research: gift, consent, and meaning
Boyes, M; Ward, P
2003-01-01
The Neuroscience Institute of Schizophrenia and Allied Disorders's (NISAD) "Gift of Hope" Tissue Donor Program is a volunteer programme for people who wish to donate their brain when they die for neuroscience research into schizophrenia. Organ donation for purposes of research differs from transplant donation in a number of ways, most notably the absence of a single recipient. Within a particular community, however, (people with schizophrenia and their carers) the single recipient is replaced by a sense of shared experience and preventing suffering in others. Donors have an investment in the research. PMID:12796437

Pressure barrels for sampling and preservation of submarine sediments under in situ pressure with the robotic sea-floor drill rig MeBo (Meeresboden-Bohrgerät) housed at the MARUM (Bremen, Germany) were developed. Deployments of the so-called MDP
(MeBo pressure vessel) during two offshore expeditions off New Zealand and off Spitsbergen, Norway, resulted in the recovery of sediment cores with pressure stages equaling in situ hydrostatic pressure. While initially designed for the quantification of gas and gas-hydrate contents in submarine sediments, the MDP also allows for analysis of the sediments under in situ pressure with methods typically applied by researchers from other scientific fields (geotechnics, sedimentology, microbiology, etc.). Here we report on the design and operational procedure of the MDP and demonstrate full functionality by presenting the first results from pressure-core degassing and molecular gas analysis.
The uptake by the canine tibia of the bone-scanning agent 99mTc-MDP before and after an osteotomy.
Hughes, S; Khan, R; Davies, R; Lavender, P
1978-11-01
The residue and extraction of technetium-labelled methylene diphosphonate (99mTc-MDP), a substance used in bone scanning, was examined in the canine tibia and found to be low. Examination of washout curves suggested that there were four compartments in cortical bone, a vascular, a perivascular, a bone fluid and a bone compartment. After an osteotomy in the canine tibia the residue of 99mTc-MDP increased. This was believed to be due to an increase in the blood supply to the bone and to an associated increase in new bone available for exchange. Bone scanning in a fracture is therefore a reflection of the vascular status of the bone being examined and of the uptake by bone. This is dependent on there being an adequate blood supply to the bone and an increased number of mineral-binding sites.

(99m)Tc-Methylene diphosphonate (MDP) triple phase bone scintigraphy (BS) has a role in early diagnosis of Kienbock's disease, especially when the X-ray is negative. Early diagnosis can result in prompt management of the patient since wrist pain in older individuals due to aging may go unnoticed or be due to other diagnoses with the production of greater damage and eventually a worse prognosis. Herein, we present a case report of a 29-year-old female with Kienbock's disease in whom the X-ray was negative and MRI incorrect. The (99m)Tc-MDP SPECT/CT BS helped the diagnosis of the disease in an early stage (stage 1) and had a clinical impact on the patient's management. Copyright © 2014 Elsevier España, S.L.U. and SEMNIM.

Financial incentives to increase Canadian organ donation: quick fix or fallacy?

Unlike the United States, the potential to increase organ donation in Canada may be sufficient to meet the need for transplantation. However, there has been no national coordinated effort to increase organ donation. Strategies that do not involve payment for organs, such as investment in health care resources to support deceased donor organ donation and introduction of a remuneration framework for the work of deceased organ donation, should be prioritized for implementation. Financial incentives that may be permitted under existing legislation and that pose little risk to existing donation sources should be advanced, including the following: payment of funeral expenses for potential donors who register their decision on organ donation during life (irrespective of the decision to donate or actual organ donation) and removal of disincentives for directed and paired exchange living donation, such as payment of wages, payment for pain and suffering related to the donor surgery, and payment of directed living kidney donors for participation in Canada's paired exchange program. In contrast, it would be premature to contemplate a regulated system of organ sales that would require a paradigm shift in the current approach to organ donation and legislative change to implement.

More than 100,000 has been raised in donations since the establishment of the endowment in 2004; this amount was matched by DivCHED. We are working toward the goal of raising 300,000—the amount needed to maintain the program in perpetuity. More donations are needed, but there are now sufficient funds on hand to introduce this award program at this year's eight regional ACS meetings.

This study was carried out to assess the blood donation practices and willingness to donate among residents of an urban slum. Cross sectional descriptive study design with a qualitative and quantitative component. Multistage sampling was used to select 400 respondents for the questionnaire interview while three FGD sessions were conducted guide among three groups of participants namely youths, men and women. The information collected was analyzed manually (FGD) and with Epi info version 3.5.3. Majority of the questionnaire respondents were female, married, traders, had at least secondary school education, with mean age of 37.6 years. Only 12.0% had donated in the past, the main reason given by non donors was that they had never been asked to donate; this was also a key finding in the FGD. Willingness to donate was positively associated with being a male, single and Christian, age was a significant predictor of previous donation while more of the previous donors were still willing to donate, more for family/friends (p=0.036) than voluntarily (p=0.001) this view was supported by the participants at the FGD. Members of this urban slum had poor practice of blood donation,had positive attitude and were willing to donate, there is need to mobilise and organise outreach blood donation programs to convert attitude into actual practice.

It has been suggested that blood donors with hereditary hemochromatosis may pose an increased infectious disease risk and adversely affect recipient outcomes. This study compares the infectious disease risk of whole blood (WB) donors enrolled as therapeutic (T) donors to voluntary WB donors to evaluate the safety of blood products provided by the T donors. This was a retrospective cohort study of all WB donations at the Australian Red Cross Blood Service who donated between January 1, 2011, and December 31, 2013, comparing a yearly mean of 11,789 T donors with 107,773 total donations and a yearly mean of 468,889 voluntary WB donors with 2,584,705 total donations. We compared postdonation notification of infectious illnesses, bacterial contamination screening results, and positive tests for blood borne viruses in T and WB donors. Rates of transfusion-transmissible infections in donations destined for component manufacture were significantly lower in therapeutic donations compared to voluntary donations (8.4 vs. 21.6 per 100,000 donations). Bacterial contamination (43.0 vs. 45.9 per 100,000 donations) and postdonation illness reporting (136.2 vs. 110.8 per 100,000 donations) were similar in both cohorts. The Australian therapeutic venisection program enables T donors to provide a safe and acceptable source of donated WB that has a low infectious disease risk profile. © 2016 AABB.

Kidney paired donation (KPD) strategies have facilitated compatible living-donor kidney transplants for end-stage renal disease patients with willing but incompatible living donors. Success has inspired further innovations that expand opportunities for kidney-paired donation. Two such innovations are the advanced donation strategy in which a donor provides a kidney before their recipient is matched, or even in need of, a kidney transplant, and deceased donor initiated chains in which chains are started with deceased donors rather than altruistic living donors. Although these innovations may expand KPD, they raise several ethical issues. Specific concerns raised by advanced donation include the management of uncertainty, the extent of donor and recipient consent, the scope of the obligation that the organization has to the kidney exchange paired recipient, the naming of alternative recipients, and the potential to unfairly advantage the recipient. Use of deceased donors for chain-initiating kidneys raises ethical issues concerning the consent process for each involved party, the prioritization of deceased donor kidneys, the allocation of chain ending kidneys, and the value of a living donor kidney versus a deceased donor kidney. We outline each ethical issue and discuss how it can be conceptualized and managed so that these KPD innovations programs are ultimately successful.
Legal and ethical aspects of organ donation and transplantation
Shroff, Sunil
2009-01-01
The legislation called the Transplantation of Human Organ Act (THO) was passed in India in 1994 to streamline organ donation and transplantation activities. Broadly, the act accepted brain death as a form of death and made the sale of organs a punishable offence. With the acceptance of brain death, it became possible to not only undertake kidney transplantations but also start other solid organ transplants like liver, heart, lungs, and pancreas. Despite the THO legislation, organ commerce and kidney scandals are regularly reported in the Indian media. In most instances, the implementation of the law has been flawed and more often than once its provisions have been abused. Parallel to the living related and unrelated donation program, the deceased donation program has slowly evolved in a few states. In approximately one-third of all liver transplants, the organs have come from the deceased donor program as have all the hearts and pancreas transplants. In these states, a few hospitals along with committed NGOs have kept the momentum of the deceased donor program. The MOHAN Foundation (NGO based in Tamil Nadu and Andhra Pradesh) has facilitated 400 of the 1,300 deceased organ transplants performed in the country over the last 14 years. To overcome organ shortage, developed countries are re-looking at the ethics of unrelated programs and there seems to be a move towards making this an acceptable legal alternative. The supply of deceased donors in these countries has peaked and there has been no further increase over the last few years. India is currently having a deceased donation rate of 0.05 to 0.08 per million population. We need to find a solution on how we can utilize the potentially large pool of trauma-related brain deaths for organ donation. This year in the state of Tamil Nadu, the Government has passed seven special orders. These orders are expected to streamline the activity of deceased donors and help increase their numbers. Recently, on July 30, 2008, the Government brought in a few new amendments as a Gazette with the purpose of putting a stop to organ commerce. The ethics of commerce in organ donation and transplant tourism has been widely criticized by international bodies. The legal and ethical principles that we follow universally with organ donation and transplantation are also important for the future as these may be used to resolve our conflicts related to emerging sciences such as cloning, tissue engineering, and stem cells.

To validate the ability of (99m)Tc-Annexin V to visualize early stage of glucocorticoid-induced femoral head necrosis by comparing with (99m)Tc-MDP bone scanning. Femoral head necrosis was induced in adult New Zealand white rabbits by intramuscular injection of methylprednisolone. (99m)Tc-Annexin scintigraphy and (99m)Tc-MDP scans were performed before and 5, 6, and 8 weeks after methylprednisolone administration. Rabbits were sacrificed at various time points and conducted for TUNEL and H&E staining. All methylprednisolone treated animals developed femoral head necrosis; at 8 weeks postinjection, destruction of bone structure was evident in H&E staining, and apoptosis was confirmed by the TUNEL assay. This was matched by (99m)Tc-Annexin V images, which showed a significant increase in signal over baseline. Serial (99m)Tc-Annexin V scans revealed that increased (99m)Tc-Annexin V uptake could be observed in 5 weeks. In contrast, there was no effect on (99m)Tc-MDP signal until 8 weeks. The TUNEL assay revealed that bone cell apoptosis occurred at 5 weeks. (99m)Tc-Annexin V is superior to (99m)Tc-MDP for the early detection of glucocorticoid-induced femoral head necrosis in the rabbit and may be a better strategy for the early detection of glucocorticoid-induced femoral head necrosis in patients.

Practical Considerations in Donation After Circulatory Determination of Death in Switzerland.
Dalle Ave, Anne L; Shaw, David M; Elger, Bernice
2017-09-01
Faced with similar issues of organ scarcity to its neighbors, Switzerland has developed donation after circulatory determination of death (DCDD) as a way to expand the organ pool since 1985. Here, we analyze the history, practical considerations, and ethical issues relating to the Swiss donation after circulatory death programs. In Switzerland, determination of death for DCDD requires a stand-off period of 10 minutes. This time between cardiac arrest and the declaration of death is mandated in the guidelines of the Swiss Academy of Medical Sciences. As in other DCDD programs, safeguards are put to avoid physicians denying lifesaving treatment to savable patients because of being influenced by receivers' interest. An additional recommendation could be made: Recipients should be transparently informed of the worse graft outcomes with DCDD programs and given the possibility to refuse such organs.
Organ Donation After Circulatory Death: Ethical Issues and International Practices.
Jericho, Barbara G
2018-05-21
Donation after circulatory death (DCD) is an increasingly utilized practice that can contribute to reducing the difference between the supply of organs and the demand for organs for transplantation. As the number of transplanted organs from DCD donors continues to increase, there is an essential need to address the ethical aspects of DCD in institutional DCD protocols and clinical practice. Ethical issues of respecting the end-of-life wishes of a potential donor, respecting a recipient's wishes, and addressing potential conflicts of interest are important considerations in developing policies and procedures for DCD programs. Although there may be diversity among DCD programs in Europe, Australia, Israel, China, the United States, and Canada, addressing ethical considerations in these DCD programs is essential to respect donors and recipients during the altruistic and generous act of organ donation.

BACKGROUND China officially launched a pilot program of organ donation after cardiac death to overcome the shortage of available organs since 2011. Voluntary organ donation by deceased citizens became the only source of transplant organs beginning January 1, 2015. To investigate public opinions on organ donation by deceased donors, and discuss the effect of these opinions on the willingness and attitude of the public regarding voluntary organ donation. MATERIAL AND METHODS We designed a questionnaire. The survey was conducted from December 2014 to January 2015 in Changsha City, and 417 valid questionnaires were recovered. RESULTS A total of 162 respondents explicitly expressed a willingness to donate organs, and 269 believed that the organ donors' relatives should be compensated. A total of 255 respondents thought it acceptable to complete the donation-consent form when receiving a driver's license. Among the respondents, 65.3% did not agree with the statement "My body is bestowed by my parents, and to donate my body parts would not display filial respect"; 88.9% agreed that "It is necessary to consider the willingness of my family"; 74.4% agreed that "Donated organs have not been fairly and appropriately used; the wealthy and celebrities have been favored"; and 61.4% agreed that "Organ donation laws and regulations are not well developed, and organ donations will result in unnecessary difficulties." More than 80% believed that organ donation and transplantation extend life. CONCLUSIONS Public opinions on organ donation after death are associated with various factors, including traditional values, religious beliefs, compensation mechanisms, donor registration, institutional credibility, and ideals.
Fostering repeat donations in Ghana.

Most African countries are challenged in recruiting and retaining voluntary blood donors by cost and other complexities and in establishing and implementing national blood policies. The availability of replacement donors who are a cheaper source of blood has not enhanced repeat voluntary donor initiatives. An overview of activities for recruiting and retaining voluntary blood donors was carried out. Donor records from mobile sessions were reviewed from 2002 to 2008. A total of 71,701 blood donations; 45,515 (63.5%) being voluntary donations with 11,680 (25%) repeat donations were collected during the study period. Donations from schools and colleges contributed a steady 60% of total voluntary whilst radio station blood drives increased contribution from 10 to 27%. Though Muslim population is less than 20%, blood collection was above the 30-donation cost-effectiveness threshold with a repeat donation trend reaching 60%. In contrast Christian worshippers provided <25 unit/session and 30% repeat donations. Repeat donation trends amongst school donors and radio blood drives were 20% and 70% respectively. Repeat donations rates have been variable amongst different blood donor groups in Kumasi, Ghana. The impact of community leaders in propagating altruism cannot be overemphasized. Programs aiming at motivating replacement donors to be repeat donors should be developed and assessed. Copyright 2009 The International Association for Biologicals. All rights reserved.
Patterns of alcohol consumption and risk of falls in older adults: a prospective cohort study.

Falls are a major health problem in older adults, but their relationship with alcohol consumption in this population remains unclear. In a cohort with 2170 older adults followed up for 3.3 years, both moderate drinking and the Mediterranean drinking pattern were associated with a lower risk of falls and injurious falls. This study aims to examine the association between certain patterns of alcohol consumption, including the Mediterranean drinking pattern (MDP), and the risk of falls in older adults. A prospective cohort with 2170 community-dwelling individuals aged ≥60 years was recruited in Spain in 2008-2010 and followed up through 2012. At baseline, participants reported alcohol consumption and, at the end of follow-up, their falls during the previous year. The MDP was defined as moderate alcohol consumption (threshold between moderate and heavy intake was 40 g/day for men and 24 g/day for women) with preference for wine and drinking only with meals. Analyses were conducted with negative binomial or logistic regression, as appropriate, and adjusted for the main confounders. Compared with never drinkers, the number of falls was lower in moderate drinkers (incidence rate ratio (95% confidence interval), 0.79 (0.63-0.99)) and drinkers with MDP (0.73 (0.56-0.96)). Also, moderate drinkers and those with MDP showed a lower risk of ≥2 falls (odds ratio (95% confidence interval), 0.58 (0.38-0.88) and 0.56 (0.34-0.93), respectively) and of falls requiring medical care (0.67 (0.46-0.96) and 0.61 (0.39-0.96), respectively). Both moderate drinking and the MDP were associated with a lower risk of falls and injurious falls in older adults. However, sound advice on alcohol consumption should balance risks and benefits.
Establishment of an oocyte donor program. Donor screening and selection.
Quigley, M M; Collins, R L; Schover, L R
1991-01-01
IVF with donated oocytes, followed by embryo placement in the uterus of a recipient who has been primed with exogenous steroids, is a successful treatment for special cases of infertility. Preliminary results indicate that the success rate in this situation is even greater than that usually seen with normal IVF (with placement of the embryos back into the uteri of the women from whom the oocytes were recovered). Although different sources for donated oocytes have been identified, the use of "excess" oocytes from IVF cycles and the attempted collection of oocytes at the time of otherwise indicated pelvic surgery have ethical and practical problems associated with their use. We have herein described the establishment of a successful program relying on anonymous volunteers who go through ovarian stimulation, monitoring, and oocyte recovery procedures solely to donate oocytes. The potential donors go through an exhaustive screening and education process before they are accepted in the program. Psychological evaluation of our potential donors indicated a great degree of turmoil in their backgrounds and a wide variety of motivations for actually participating. Despite the extensive educational and screening process, a substantial percentage of the donors did not complete a donation cycle, having either voluntarily withdrawn or been dropped because of lack of compliance. Further investigation of the psychological aspects of participating in such a program is certainly warranted. The use of donated oocytes to alleviate specific types of infertility is quite successful, but the application of this treatment is likely to be limited by the relative unavailability of suitable oocyte donors.

Little is known about the experiences of individuals donating peripheral blood stem cells (PBSCs) or marrow for a second time. To study this, unrelated donors making a second donation through the National Marrow Donor Program between 2004 and 2013 were evaluated. Experiences of second-time donors giving marrow (n = 118: first donation was PBSC in 76 and marrow in 42) were compared with those making only 1 marrow donation (n = 5829). Experiences of second-time donors giving PBSCs (n = 602) (first donation was PBSCs in 362; marrow in 240) were compared to first-time PBSC donors (n = 16,095). For donors giving a second PBSC or marrow donation there were no significant differences in maximum skeletal pain, maximum symptoms measured by an established modified toxicity criteria, and recovery time compared with those who donated only once. Notably, the yield of marrow nucleated cells and PBSC CD34 + cells with second donations was less. As previously noted with single first-time donations, female (PBSCs and marrow) and obese donors (PBSCs) had higher skeletal pain and/or toxicity with a second donation. PBSC donors who experienced high levels of pain or toxicity with the first donation also experienced high levels of these symptoms with their second donation and slower recovery times. In conclusion, for most donors second donation experiences were similar to first donation experiences, but CD34 + yields were less. Knowledge of the donor's first experience and stem cell yields may help centers decide whether second donations are appropriate and institute measures to improve donor experiences.

The study was set to determine whether knowledge and attitudes toward organ donation differ according to geographical location. Self-administered questionnaires were employed to collect data such as demographic characteristics, basic knowledge, attitudes and source of information about organ donation from subjects in rural and urban areas. The questionnaires were distributed randomly to 1,000 individuals in both areas during 2008. The data were analyzed in a descriptive fashion. Despite similarities in knowledge and attitudes of respondents in both areas, rural respondents were less likely to have information about organ donation, to report willingness to donate organs, and to have knowledge about "brain death" or the "organ donation card" than their counterparts in urban areas. The study identified that the principle respondents' source of information about organ donation was the television. More than 90% of respondents in rural and urban areas reported that the contribution of health care providers in providing them with knowledge about organ donation and transplantation was "none" or "little". Respondents identified several reasons, which may influence their decisions to donate organs. In conclusion, the deficit in knowledge and attitudes of rural respondents about organ donation may be justified by the lack of information about this significant issue. Accordingly, health facilities, local mass media and educational institutions should provide intensive educational programs to encourage the public donate organs.

Comprehensive school health (CSH) is increasingly receiving renewed interest as a strategy to improve health and learning. The present study estimates the costs associated with implementing and maintaining CSH. We reviewed the accounting information of all schools in the Annapolis Valley Health Promoting Schools (AVHPS) program in 2008/2009. We considered support for nutrition and physical activity programs by the public system, grants, donations, fundraising and volunteers. The annual public funding to AVHPS to implement and maintain CSH totaled $344,514, which translates, on average, to $7,830 per school and $22.67 per student. Of the public funding, $140,500 was for CSH, $86,250 for breakfast programs, $28,750 for school food policy programs, and the remainder for other subsidized programs. Grants, donations and fundraising were mostly locally acquired. They totaled $127,235, which translates, on average, to $2,892 per school or $8.37 per student. The value of volunteer support was estimated to be equivalent to the value of grants, donations and fundraising combined. Of all grants, donations, fundraising and volunteers, 20% was directed to physical activity programs and 80% to nutrition programs. The public costs to implement and maintain CSH are modest. They leveraged substantial local funding and in-kind contributions, underlining community support for healthy eating and active living. Where CSH is effective in preventing childhood overweight, it is most likely cost-effective too, as costs for future chronic diseases are mounting. CSH programs that are proven effective and cost-effective have enormous potential for broad implementation and for reducing the public health burden associated with obesity.
Relay kidney transplantation in Korea--legal, ethical and medical aspects.
Park, Jong-Hyun; Park, Joong-Won; Koo, Young-Mo; Kim, Jang Han

Living kidney transplantations constitute the majority of kidney transplantations in Korea. Recently, relay kidney transplantation, which is a modified form of both 'exchange transplantation' and 'living anonymous donation', has become at issue. After a living anonymous donor makes the initial donation, the next donor, who is related to the first recipient, makes the second donation; the third donor, who is related to the second recipient, makes the third donation; and so on. In relay kidney transplantation, organ trafficking, coercion of donation, assessment order, breach of agreement, and recipient burden should be evaluated with respect to ethical, legal and medical considerations. Despite these problems, a non-governmental body, the Korean Organ and Tissue Donor Program, has been promoting relay kidney transplantations to address the shortage of cadaveric kidney donations. Acceptance of the method of relay kidney transplantation requires the institution of supplementary measures to minimize the related problems.

Several challenging obstacles remain to increasing the number of organ donations from deceased patients in a hospital setting. These include medical, administrative, and ethical issues. Possible medical obstacles include the failure of early recognition of possible donors and inadequate care of potential and actual donors. To maximize the use of donated organs, proper care of the donors and expedited donor consent cannot be overemphasized. The care rendered to patients should ensure appropriate perfusion and nutrition of the organs, with meticulous follow-up until organ recovery. For example, patients involved in accidents are presumed to be healthy, but many have no available medical history on file. At the time of organ recovery, unexpected infections or malignancies can be minimized by raising the index of suspicion of the presence of serious conditions in donors, especially in donors with unknown medical history. A careful physical examination and an appropriate and aggressive laboratory investigation may disclose the cause of suspected clinical conditions in these potential donors. Individuals who work in intensive care units are the main group of health care providers directly involved in the process of organ donation. Appointing a donor coordinator in each intensive care unit could improve all aspects of organ donation. Such coordination could harmonize efforts toward the goals mentioned above and surmount the obstacles encountered during deceased-donor organ donation. Here, we describe the preliminary results of the Proactive Detection Program, a collaboration between the Saudi Center for Organ Transplantation (the national organ donation and transplant supervising center) and intensive care units of donating hospitals. With its success in Saudi Arabia, it is hoped that it will be widely adopted in other regions.
Sperm donor anonymity and compensation: an experiment with American sperm donors
Cohen, Glenn; Coan, Travis; Ottey, Michelle; Boyd, Christina

Abstract Most sperm donation that occurs in the USA proceeds through anonymous donation. While some clinics make the identity of the sperm donor available to a donor-conceived child at age 18 as part of ‘open identification’ or ‘identity release programs,’ no US law requires clinics to do so, and the majority of individuals do not use these programs. By contrast, in many parts of the world, there have been significant legislative initiatives requiring that sperm donor identities be made available to children after a certain age (typically when the child turns 18). One major concern with prohibiting anonymous sperm donation has been that the number of willing sperm donors will decrease leading to shortages, as have been experienced in some of the countries that have prohibited sperm donor anonymity. One possible solution, suggested by prior work, would be to pay current anonymous sperm donors more per donation to continue to donate when their anonymity is removed. Using a unique sample of current anonymous and open identity sperm donors from a large sperm bank in the USA, we test that approach. As far as we know, this is the first attempt to examine what would happen if the USA adopted a prohibition on anonymous sperm donation that used the most ecologically valid population, current sperm donors. We find that 29% of current anonymous sperm donors in the sample would refuse to donate if the law changed such that they were required to put their names in a registry available to donor-conceived children at age 18. When we look at the remaining sperm donors who would be willing to participate, we find that they would demand an additional $60 per donation (using our preferred specification). We also discuss the ramifications for the industry. PMID:28852536
Abnormal scintigraphic evolution in AA hepatic amyloidosis

Lomena, F.; Rosello, R.; Pons, F.
1988-03-01
A patient with AA amyloidosis secondary to ankylosing spondylitis showed intense liver uptake of Tc-99m MDP on bone imaging. The biopsy showed hepatic amyloid deposition. A repeat bone scan with Tc-99m MDP 1 year later was negative, although the clinical signs and liver function tests of the patient had not changed. A mechanism might exist, other than the affinity of amyloid to calcium, which would explain the extraosseous uptake of pyrophosphates and diphosphonates in organs and soft tissues affected by systemic amyloidosis.
An Approach for Dynamic Optimization of Prevention Program Implementation in Stochastic Environments
NASA Astrophysics Data System (ADS)
Kang, Yuncheol; Prabhu, Vittal
The science of preventing youth problems has significantly advanced in developing evidence-based prevention program (EBP) by using randomized clinical trials. Effective EBP can reduce delinquency, aggression, violence, bullying and substance abuse among youth. Unfortunately the outcomes of EBP implemented in natural settings usually tend to be lower than in clinical trials, which has motivated the need to study EBP implementations. In this paper we propose to model EBP implementations in natural settings as stochastic dynamic processes. Specifically, we propose Markov Decision Process (MDP) for modeling and dynamic optimization of such EBP implementations. We illustrate these concepts using simple numerical examples and discuss potential challenges in using such approaches in practice.
A systematic review and meta-analysis of antecedents of blood donation behavior and intentions.
Bednall, Timothy C; Bove, Liliana L; Cheetham, Ali; Murray, Andrea L
2013-11-01
This meta-analysis sought to identify the strongest antecedents of blood donation behavior and intentions. It synthesized the results of 24 predictive correlational studies of donation behavior and 37 studies of donation intentions. The antecedents were grouped into six research programs: (1) the Theory of Planned Behavior (TPB) and its extensions, (2) prosocial motivation, (3) affective expectations, (4) donor site experience, (5) past donation behavior, and (6) donor demographics. Antecedent categories were cross-validated by multiple coders, and combined effect sizes were analyzed using a random-effects model. For donation behavior, medium positive associations were found with five of the constructs from the extended TPB: intentions to donate, perceived behavioral control, attitude toward donation, self-efficacy and donor role identity. Other antecedents displaying a positive association with donation behavior included anticipated regret for not donating, number of past donations and donor age. Donor experiences at the collection site in the form of temporary deferral or adverse reactions had a medium negative association with behavior. For donation intentions, strong positive associations were observed for perceived behavioral control, attitude, self-efficacy, role identity and anticipated regret. Medium positive associations were observed for personal moral norm, subjective norm, satisfaction, and service quality. All other potential antecedents had weak or non-significant associations with behavior and intentions. Several of these associations were moderated by between-study differences, including donor experience, the period of data collection in which donation behavior was observed, and the use of a nominal (yes/no return) versus a ratio measure of donation behavior. Collectively, the results underscore the importance of enhancing donors' attitudes towards donation and building their perceived behavioral control and self-efficacy to donate. Further, minimizing the risk of adverse reactions and enacting re-recruitment policies for temporarily deferred donors will help protect future donation behavior. Implications of these findings for blood collection agencies and researchers are discussed. Copyright © 2013 Elsevier Ltd. All rights reserved.

Introduction In Saudi Arabia, voluntary donors are the only source of blood donation. The aim of this study was to assess the level of public knowledge and attitude toward blood donation in Saudi Arabia. Methods Using a previously validated questionnaire that comprises 38 questions to assess the levels of knowledge, attitudes, and motivations towards blood donation, 469 Saudi adults who attended different shopping malls in Riyadh, Saudi Arabia were surveyed. Multiple regression analyses were used to identify the significant predictors of blood donation, with the significance set at P<0.05. Results Approximately half of all subjects (53.3%) reported that they had previously donated blood, 39% of whom had donated more than once. The knowledge percentage mean score was 58.07%, denoting a poor level of knowledge, with only 11.9% reporting a good level of knowledge. The attitude percentage mean score towards donation was 75.45%, reflecting a neutral attitude towards donating blood, with 31.6% reporting a positive attitude. Donation was significantly more prevalent among males than females (66% versus 13.3%; P<0.001). After adjustment for confounders, a higher knowledge score (t=2.59; P=0.01), a higher attitude score (t=3.26; P=0.001), and male sex (t=10.45; P<0.001) were significant predictors of blood donation. An inability to reach the blood donation centers and a fear of anemia were the main reasons for females not donating blood (49.9% and 35.7%, respectively), whereas a lack of time was the main reason for males (59.5%). Conclusion Prevalence of blood donation was less than satisfactory among the Saudi public, probably due to misconceptions, poor knowledge, and unfavorable attitude to donation. Educational programs are necessary to increase the level of knowledge and improve the attitude of the Saudi public toward blood donation. Providing mobile blood collection units nearer to individuals’ places of work to reduce their time costs of donating is a necessity. PMID:25152628
[Marketing role of corneal graft tissue donation to an eye bank and donors' socioeconomic profile].
Farias, Roberta Jansen de Mello; Sousa, Luciene Barbosa de
2008-01-01
Penetrating keratoplasty has been the leading and the most successful type of transplant in the world, however corneal deficiency is a commom problem usually presented to corneal surgeons. Impact evaluation of the number of corneal graft donations to the Sorocaba Eye Bank after the implementation of a corneal graft procurement system; to draw the socioeconomic profile of corneal graft donors of the Sorocaba Eye Bank (SEB). Retrospective study on donations to SEB from its creation and after the development of media marketing. Prospective analysis of the socioeconomic profile of corneal graft donors by a questionnaire sent as letters to the families of the donors in a certain month. SEB began its work in 1971 by spreading need of organ donation through lectures in churches, shopping malls, community meetings, radio programs, television programs, etc. In the 70s, the number of retrieved corneal grafts was 1 or 2/month. Between 1984 - 1989 a procurement coordination team was trained to act in mortuaries and by 2000 they also began to work in public hospitals. In 1984 only 260 corneal grafts were retrieved. This number has been increasing to 2,778 corneal graft donations in 2004. The questionnaire was answered by 76 of the 93 donor families, with a response rate of 81.7%. Donor age had a mean of 65.1 +/- 14.7 y/o, forty-two (55.3%) were men. Educational level of the donor families was an important factor for organ donation, once 36.8% had concluded high school and 34.2% completed university. The great majority, sixty-three (82.9%) of the corneal grafts were donated through the efforts of the procurement coordination team. The role of the media and institutional credibility are mandatory for public commitment to organ donation. The proficiency of the procurement coordination team requires intensive training, as the results show that 82.9% donations were made thanks to their efforts.

Describe unexpected events (UEs) that occurred during blood donation in cats with and without sedation. Retrospective observational study (2010-2013). University teaching hospital. Client-owned healthy cats enrolled in a blood donation program. None. Blood collection for transfusion was performed 115 times from 32 cats. Seventy donation events were in unsedated cats and 45 in sedated cats. For each collection, the anticipated blood volume to be collected, actual blood volume collected, sedation protocol, and any UE in the peridonation period were recorded. There were 6 categories of UEs: movement during donation, donor anxiety, inadequate collected blood volume, jugular vessel related UEs, additional sedation requirement, and cardiorespiratory distress. Fisher's exact test was used to compare the frequency of UEs between sedated and unsedated cats. UEs were recorded in 54 of 115 collections. In the donor population, movement was reported as an UE in 0 cats that donated under sedation and 24/70 (34.3%) cats that donated without sedation (P < 0.001). Donor anxiety occurred in 2/45 (4.4%) cats that donated under sedation and 14/70 (20.0%) cats that donated unsedated (P = 0.014). Unsedated donation did not increase the likelihood of inadequate donation volume, jugular vessel related UEs, or cardiorespiratory distress. Eight of 45 (17.8%) sedated donations required additional sedation. Movement during donation and signs of donor anxiety were more frequent in unsedated cats. These were considered minor issues, expected in unsedated cats being gently restrained. Blood collection from unsedated feline donors is a viable alternative to sedated donation. © Veterinary Emergency and Critical Care Society 2017.
(n, N) type maintenance policy for multi-component systems with failure interactions

Zhang, Zhuoqi; Wu, Su; Li, Binfeng; Lee, Seungchul
2015-04-01
This paper studies maintenance policies for multi-component systems in which failure interactions and opportunistic maintenance (OM) involve. This maintenance problem can be formulated as a Markov decision process (MDP). However, since an action set and state space in MDP exponentially expand as the number of components increase, traditional approaches are computationally intractable. To deal with curse of dimensionality, we decompose such a multi-component system into mutually influential single-component systems. Each single-component system is formulated as an MDP with the objective of minimising its long-run average maintenance cost. Under some reasonable assumptions, we prove the existence of the optimal (n, N) type policy for a single-component system. An algorithm to obtain the optimal (n, N) type policy is also proposed. Based on the proposed algorithm, we develop an iterative approximation algorithm to obtain an acceptable maintenance policy for a multi-component system. Numerical examples find that failure interactions and OM pose significant effects on a maintenance policy.

Data volume is getting larger every day in Mask Data Preparation (MDP). In the meantime, faster data handling is always required. MDP flow typically introduces Distributed Processing (DP) system to realize the demand because using hundreds of CPU is a reasonable solution. However, even if the number of CPU were increased, the throughput might be saturated because hard disk I/O and network speeds could be bottlenecks. So, MDP needs to invest a lot of money to not only hundreds of CPU but also storage and a network device which make the throughput faster. NCS would like to introduce new distributed processing system which is called "NDE". NDE could be a distributed disk system which makes the throughput faster without investing a lot of money because it is designed to use multiple conventional hard drives appropriately over network. NCS studies I/O performance with OASIS® data format on NDE which contributes to realize the high throughput in this paper.
Optimal Navigation of Self-Propelled Colloids in Microstructured Mazes
NASA Astrophysics Data System (ADS)
Yang, Yuguang; Bevan, Michael
Controlling navigation of self-propelled microscopic `robots' subject to random Brownian motion in complex microstructured environments (e.g., porous media, tumor vasculature) is important to many emerging applications (e.g., enhanced oil recovery, drug delivery). In this work, we design an optimal feedback policy to navigate an active self-propelled colloidal rod in complex mazes with various obstacle types. Actuation of the rods is modelled based on a light-controlled osmotic flow mechanism, which produces different propulsion velocities along the rod's long axis. Actuator-parameterized Langevin equations, with soft rod-obstacle repulsive interactions, are developed to describe the system dynamics. A Markov decision process (MDP) framework is used for optimal policy calculations with design goals of colloidal rods reaching target end points in minimum time. Simulations show that optimal MDP-based policies are able to control rod trajectories to reach target regions order-of-magnitudes faster than uncontrolled rods, which diverges as maze complexity increases. An efficient multi-graph based implementation for MDP is also presented, which scales linearly with the maze dimension.

A methodology is described wherein a calibrated model-based `Virtual' Variable Shaped Beam (VSB) mask writer process simulator is used to accurately verify complex Optical Proximity Correction (OPC) and Inverse Lithography Technology (ILT) mask designs prior to Mask Data Preparation (MDP) and mask fabrication. This type of verification addresses physical effects which occur in mask writing that may impact lithographic printing fidelity and variability. The work described here is motivated by requirements for extreme accuracy and control of variations for today's most demanding IC products. These extreme demands necessitate careful and detailed analysis of all potential sources of uncompensated error or variation and extreme control of these at each stage of the integrated OPC/ MDP/ Mask/ silicon lithography flow. The important potential sources of variation we focus on here originate on the basis of VSB mask writer physics and other errors inherent in the mask writing process. The deposited electron beam dose distribution may be examined in a manner similar to optical lithography aerial image analysis and image edge log-slope analysis. This approach enables one to catch, grade, and mitigate problems early and thus reduce the likelihood for costly long-loop iterations between OPC, MDP, and wafer fabrication flows. It moreover describes how to detect regions of a layout or mask where hotspots may occur or where the robustness to intrinsic variations may be improved by modification to the OPC, choice of mask technology, or by judicious design of VSB shots and dose assignment.

We have developed a new micro-discharge plasma (MDP)-based gene transfection method, which transfers genes into cells with high efficiency and low cytotoxicity; however, the mechanism underlying the method is still unknown. Studies revealed that the N-acetylcysteine-mediated inhibition of reactive oxygen species (ROS) activity completely abolished gene transfer. In this study, we used laser-produced plasma to demonstrate that gene transfer does not occur in the absence of electrical factors. Our results show that both electrical and chemical factors are necessary for gene transfer inside cells by microplasma irradiation. This indicates that plasma-mediated gene transfection utilizes the synergy between electrical and chemical factors. The electric field threshold required for transfection was approximately 1 kV m-1 in our MDP system. This indicates that MDP irradiation supplies sufficient concentrations of ROS, and the stimulation intensity of the electric field determines the transfection efficiency in our system. Gene transfer by plasma irradiation depends mainly on endocytosis, which accounts for at least 80% of the transfer, and clathrin-mediated endocytosis is a dominant endocytosis. In plasma-mediated gene transfection, alterations in electrical and chemical factors can independently regulate plasmid DNA adhesion and triggering of endocytosis, respectively. This implies that plasma characteristics can be adjusted according to target cell requirements, and the transfection process can be optimized with minimum damage to cells and maximum efficiency. This may explain how MDP simultaneously achieves high transfection efficiency with minimal cell damage.
Application of the unified mask data format based on OASIS for VSB EB writers

2005-11-01
Mask data preparation (MDP) for modern mask manufacturing becomes a complex process because many kinds of EB data formats are used in mask makers and EB data files continue to become bigger by the application of RET. Therefore we developed a unified mask pattern data format named "OASIS.VSB1" and a job deck format named "MALY2" for Variable-Shaped-Beam (VSB) EB writers. OASIS.VSB is the mask pattern data format based on OASISTM 3 (Open Artwork System Interchange Standard) released as a successive format to GDSII by SEMI. We defined restrictions on OASIS for VSB EB writers to input OASIS.VSB data directly to VSB EB writers just like the native EB data. OASIS.VSB specification and MALY specification have been disclosed to the public and will become a SEMI standard in the near future. We started to promote the spread activities of OASIS.VSB and MALY. For practical use of OASIS.VSB and MALY, we are discussing the infrastructure system of MDP processing using OASIS.VSB and MALY with mask makers, VSB EB makers, and device makers. We are also discussing the tools for the infrastructure system with EDA vendors. The infrastructure system will enable TAT, the man-hour, and the cost in MDP to be reduced. In this paper, we propose the plan of the infrastructure system of MDP processing using OASIS.VSB and MALY as an application of OASIS.VSB and MALY.

Kidney transplantation is a lifesaving medical treatment. However, very high demand for kidneys with low kidney donation causes a black market that exploits patients' desperation and donors' vulnerability. The current kidney donation programs fail to produce promising results to avoid illegal and unethical kidney trafficking and commercialism. Even though the primary goal of kidney donation is to increase the number of deceased organ donations, in some countries, like Turkey, due to religious or cultural concerns, it is impossible to supply adequate deceased kidney donations. In this view, the aim of this paper is to examine kidney trafficking in the scope of Turkey's current organ donation system and propose a new model, named the Incentivized Kidney Donation Model (IKDM), to increase kidney donation from living donors. The model encompasses the following benefits offered to kidney donors; lifetime health insurance, exemptions from copayments/contribution shares, priority when receiving an organ, priority when finding a job, income tax exemptions for salaried employees, and free or discounted public utilities. This normative model has the potential to promote donors' altruistic acts as well as the solidarity and loyalty among members of a society without violating ethical values and internationally accepted principles. © 2018 John Wiley & Sons Ltd.
[An exploratory study regarding the hypothetical human embryo donation in Chile].
Alvarez Díaz, J A
2007-12-01
To explore opinions of patients who undergone to complex ART towards gamete and embryo donation, as well as the reasons to do it or not. The seat was the Hospital Clínico de la Universidad de Chile. There were interviewed ten participants (seven women, three men), who had undergone at least to one ART, without comprising of donation programs. It was a cross-sectional study of descriptive bioethics, done with ethnographic qualitative methodology with a semistructured interview applying speech analysis to the resulting text. Regarding embryo donation, six participants would accept to donate them, five to fertility therapy and one to research. Regarding the cryopreservation, three participants would always accept it, and three with some restrictions, just one on them would rather to discard instead of donating a cryopreserved embryo. It could be suggested: gamete donation is more commented and generally accepted; embryo donation is a more conflicting and less discussed subject, as much to donate as to accept; cryopreservation is a complex subject, commented but also conflicting, whose acceptance or not, as well as the destiny of the probably cryopreserved embryos, depends on the believes that participants have about the origin of the life, personal ethics, and the religion. It could be possible to say that a hypothesis constructed in this study (to be verified in future quantitative researches) is that embryo donation could take place, for therapy of fertility, and exceptionally to research.
Deceased Donor Organs: What Can Be Done to Raise Donation Rates Using Evidence From Malaysia?

Organ donation rates have continued to fall seriously short of needs worldwide, with the lowest rates recorded among developing economies. This study seeks to analyze evidence from a developing economy to explore the usefulness of social psychological theory to solve the problem. The study deployed a large survey (n = 10 412) using a convenience sampling procedure targeted at increasing the number of Malaysians registered with the Ministry of Health, Malaysia who are willing to donate organs upon death. Structural equation modeling was deployed to estimate simultaneously the relative influence of cognitive and noncognitive variables on willingness to donate deceased organs. The cognitive factors of donation perception, socioeconomic status and financial incentives, and the noncognitive factors of demography and fear showed a high statistically significant (1%) relationship with willingness to donate organs after death. While financial incentives were significant, cash rewards showed the least impact. Donation perception showed the highest impact, which shows that the development of effective pedagogic programs with simultaneous improvements to the quality of services provided by medical personnel engaged in retrieving and transplanting deceased donor organs can help raise organ donation rates. © Copyright 2015 The American Society of Transplantation and the American Society of Transplant Surgeons.
Human body donation programs in Sri Lanka: Buddhist perspectives.
Subasinghe, Sandeepani Kanchana; Jones, D Gareth
2015-01-01
Considerable attention is being given to the availability of bodies for anatomical education. This raises the question of the manner in which they are obtained, that is, whether they are unclaimed or donated. With increasing emphasis upon the ethical desirability of using body bequests, the spotlight tends to be focused on those countries with factors that militate against donations. However, little attention has been paid to cultures where donations are readily available. One such country is Sri Lanka where the majority of the Buddhist population follows Theravada Buddhism. Within this context, the expectation is that donations will be given selflessly without expecting anything in return. This is because donation of one's body has blessings for a better outcome now and in the afterlife. The ceremonies to honor donors are outlined, including details of the "Pirith Ceremony." The relevance for other cultures of these features of body donation is discussed paying especial attention to the meaning of altruism and consent, and justification for the anonymization of cadavers. The degree to which anatomy is integrated into the surrounding culture also emerges as significant. © 2015 American Association of Anatomists.

To estimate the associations of nationality, university program, donation history and gender, with blood donation barriers experienced by non-donating students on the day of a campus blood drive. This project focused particularly on nationality and the effect of the different blood donation cultures in the students' countries of origin. A retrospective cohort study of 398 North American and Caribbean university students was conducted at St. George's University, Grenada, in 2010. Data were collected from non-donating students on campus while a blood drive was taking place. Log-binomial regression was used to estimate associations between the exposures of interest and donation barriers experienced by the students. North American (voluntary blood donation culture) students were more likely than Caribbean (replacement blood donation culture) students to experience "Lack of Time" (relative risk (RR) = 1.57; 95% confidence interval (CI): 1.19-2.07) and "Lack of Eligibility" (RR = 1.55; 95% CI: 1.08-2.22) as barriers to donation. Conversely, Caribbean students were a third as likely to state "Lack of Incentive" (RR = 0.32; 95% CI: 0.20-0.50), "Fear of Infection" (RR = 0.35; 95% CI: 0.21-0.58), and "Fear of Needles" (RR = 0.32; 95% CI: 0.21-0.48) were barriers than North American students. University students from voluntary blood donation cultures are likely to experience different barriers to donation than those from replacement cultures. Knowledge of barriers that students from contrasting blood donation systems face provides valuable information for blood drive promotion in university student populations that contain multiple nationalities.

Cadaver dissection stands as a crucial component in medical curricula around the world, although computer-based multimedia programs have been introduced in order to replace the need for cadaver donations. Due to a decrease in the number of unclaimed bodies and rather few donations, there is an insufficient number of cadavers for anatomical studies in Iran. This study was carried out to evaluate medical students' awareness and willingness regarding body donation in Kashan University of Medical Sciences, Iran. In this study, a questionnaire was designed to focus on the cultural acceptability and personal willingness to donate one's body after death. Students from the university's anatomy classes (n = 331) participated in this study. Seventy-seven percent of the students expressed their agreement toward the idea of utilizing body donation services, though only 25.4% of participants were willing to donate their own bodies. None of the demographic factors were associated with cultural acceptability or personal willingness towards body donation. These findings indicated that besides "payment", other factors were associated with students' willingness to become donors. All factors of awareness except "previous awareness of organization" were associated with cultural acceptability. In this study, students suggested that encouraging people to register for body donation using mass media (25.6%) and teaching students to respect cadavers in the dissection environment (24.8%) were the best solutions for addressing the lack of cadavers. These findings indicated that a lack of awareness about body donation might be the main factor responsible for unwillingness towards body donation; therefore, improving the public's awareness and addressing the willingness of students regarding body donation may help overcome the current lack of donated cadavers.

The impact of living-unrelated transplant on establishing deceased-donor liver program in Syria.
Saeed, Bassam
2014-10-01
Liver transplant is the criterion standard for patients with end-stage liver disease. Yet there is no liver transplant in Syria. Traveling abroad for a liver transplant is a luxury few Syrians can afford. There is currently an on-going debate whether to start a liver transplant program using living or deceased donors. In 2003, a new law was enacted, authorizing the use of organs from volunteer strangers and deceased donors. Despite the positive aspects of this law (allowing unrelated donors to increase the number of transplants in the country); the negative aspects also were obvious. The poor used the law to sell their organs to the rich, and this model is in violation of the Istanbul Declaration. To better document transplant communities' perceptions on organ donation, an e-mail survey was sent to a nationally representative sample of physicians (n = 115) that showed that 58% of respondents did not support the start of liver transplant from live donors, as they fear a considerable risk for the donor and the recipient. Seventy-one percent of respondents believe that unrelated kidney donation has contributed to tarnishing the reputation of transplant, and 56% believe that a deceased-donor program can run in parallel with unrelated organ donations. The interest in deceased-donor program has been affected negatively by the systematic approach of using poor persons as the source of the organ. This lack of interest has affected starting a liver program that relies on deceased donors; especially the need for kidneys is more than livers. Health authorities in Syria were inclined to initiate a liver transplant program from live donors, despite the risks of serious morbidities and mortality. In conclusion then, paid kidney donation in actual effect is actually a hindrance to establishing a deceased-donor liver program.

This paper proposes a Markov decision process (MDP) model that features both discrete and continuous state variables. We extend previous work by Boyan and Littman on the mono-dimensional time-dependent MDP to multiple dimensions. We present the principle of lazy discretization, and piecewise constant and linear approximations of the model. Having to deal with several continuous dimensions raises several new problems that require new solutions. In the (piecewise) linear case, we use techniques from partially- observable MDPs (POMDPS) to represent value functions as sets of linear functions attached to different partitions of the state space.

Organ procurement: Spanish transplant procurement management.
Manyalich, Martí; Mestres, Carlos A; Ballesté, Chloë; Páez, Gloria; Valero, Ricard; Gómez, María Paula
2011-06-01
Transplantation is an accepted therapeutic option to save or improve the quality of life when organ failure occurs or tissue replacements are needed. However, the lack of organs is the major limitation. The deceased organ procurement organization and professionals provide the solution to this international problem. In this review, we identify the elements involved in the organ procurement management process to analyze the possibility of implementation of deceased organ procurement for a transplantation program. While the donation rates are subject to several negative factors including religious, economic, cultural, and legal issues, the existence of well-trained professionals may considerably increase them. Professional training in organ donation along with the establishment of a solid organizational system has been identified as the crucial factor in developing efficient organ donation and transplantation programs.

The media affects individuals' behaviors, especially by means of news and advertisements. In this study, we evaluated health content of organ donation and transplantation news in the printed media and on television programs for a 1-year period in Turkey. We examined 2449 news items in 230 newspapers and magazines; 1179 news programs on 45 television channels, all concerning organ donation and transplantation. The news obtained from the Media Pursuit Center were transferred to an electronic file to evaluate the format and content of the news. Nine variables were examined about the scope and the formal characteristics of the news: the publication name, its type, the province, the date, the headline, the title length, the presence of a photograph, or its kind, the news size, and the page number. In the content analysis of the news, we also examined 9 variables: the topic, the message of the headline, the property of the words in the title, the identification of photographs in the news, the age, gender of actors in the news, as well as donor or recipient. In a summary, print media and television channels, failed to show sufficient information about organ donation and transplantation. The percentage of news about organ donation and transplantation was small and mostly negative items in the media. On television channels, sufficient place was not given to organ donation and transplantation. The news in printed media and on television channels was not about motivated or altruistic behavior. The pattern of organ donation and transplantation news is important in terms of perception and comment by the public. Furthermore it directly affects the perception of the news by the reader.

To assess the knowledge and attitude of school-going adolescents regarding corneal donation in government and private schools in an urban area of Northern India. A school-based cross-sectional study was conducted in an urban field practice area of Post Graduate Institute of Medical Education and Research (PGIMER), Chandigarh, India. A total of 365 participants of the seventh to 10th grade were enrolled from a government school and a private school. A pretested, semistructured, self-administered, bilingual (English and Hindi) questionnaire was used to assess the sociodemographic profile and knowledge and attitude related to corneal donation. Most (87%) (confidence interval, 83.1%-90.0%) participants had heard about corneal donation. Only 2% of students answered all the knowledge-related questions correctly. None knew about the national toll-free number for corneal donation. Three-fourth (72%) supported the idea of corneal donation. Of them, only 44% (confidence interval, 41.0-47.1) were willing to pledge to donate their own eyes. Fears and myths were the persistent barriers. The government and private schools differed in both knowledge and attitude, with the latter performing better. Knowledge among the selected high school children was poor. Although many supported the idea, only a few were willing to donate. We suggest that program components be evaluated from time to time. Future studies should explore the role of strengthening Information Education and Communication (IEC) activities among high school students for motivating community members to pledge to donate for corneal donation.

For many of the end-stage organ diseases, organ transplantation is the most preferred treatment. The need for the organ transplantation is higher than the availability. For the transplantation program to be successful, awareness regarding organ donation is needed and people must have a positive attitude toward donating organs. This study aims to assess the awareness and attitudes regarding organ donation among the rural population and to evaluate the sociodemographic factors associated with their awareness. This community-based cross-sectional study was conducted among 360 people living in 4 villages of Puducherry. Face-to-face interviews were carried out using pretested questionnaire, which included the sociodemographic data. Data were entered into Excel and analyzed using Statistical Package for Social Sciences. Of 360 participants, 88% (317/360) were aware of organ donation. Among these 317 participants, awareness was highest in the age group 18-30 years 98.8% (87/88), male 91% (147/161), higher secondary and above 100% (58/58), and Class 1 socioeconomic status 92% (13/14). Source of awareness about organ donation was primarily through media 83% (263/317). The majority of the participants 88% (281/317) felt that the purpose of organ donation was to save life. Most of the participants 91% (290/317) said that all healthy adults are eligible organ donors and 87% (275/317) of the participants said that monetary benefits could not be accepted for organ donation. Most of the participants 70% (223/317) were willing to donate their organs after death. Among the participants who refused to donate their organs, family refusal 57% (25/44) was the most common reason. This study shows that there is a high level of awareness about organ donation among rural people and most of the participants are willing to donate their organs.

To describe end-of-life care practices relevant to organ donation in patients with devastating brain injury in Spain. A multicenter prospective study of a retrospective cohort. 1 November 2014 to 30 April 2015. Sixty-eight hospitals authorized for organ procurement. Patients dying from devastating brain injury (possible donors). Age: 1 month-85 years. Type of care, donation after brain death, donation after circulatory death, intubation/ventilation, referral to the donor coordinator. A total of 1,970 possible donors were identified, of which half received active treatment in an Intensive Care Unit (ICU) until brain death (27%), cardiac arrest (5%) or the withdrawal of life-sustaining therapy (19%). Of the rest, 10% were admitted to the ICU to facilitate organ donation, while 39% were not admitted to the ICU. Of those patients who evolved to a brain death condition (n=695), most transitioned to actual donation (n=446; 64%). Of those who died following the withdrawal of life-sustaining therapy (n=537), 45 (8%) were converted into actual donation after circulatory death donors. The lack of a dedicated donation after circulatory death program was the main reason for non-donation. Thirty-seven percent of the possible donors were not intubated/ventilated at death, mainly because the professional in charge did not consider donation alter discarding therapeutic intubation. Thirty-six percent of the possible donors were never referred to the donor coordinator. Although deceased donation is optimized in Spain, there are still opportunities for improvement in the identification of possible donors outside the ICU and in the consideration of donation after circulatory death in patients who die following the withdrawal of life-sustaining therapy.

Background Dietary patterns can substantially vary the resource consumption and environmental impact of a given population. Dietary changes such as the increased consumption of vegetables and reduced consumption of animal products reduce the environmental footprint and thus the use of natural resources. The adherence of a given population to the Mediterranean Dietary Pattern (MDP) through the consumption of the food proportions and composition defined in the new Mediterranean Diet pyramid can thus not only influence human health but also the environment. The aim of the study was to analyze the sustainability of the MDP in the context of the Spanish population in terms of greenhouse gas emissions, agricultural land use, energy consumption and water consumption. Furthermore, we aimed to compare the current Spanish diet with the Mediterranean Diet and in comparison with the western dietary pattern, exemplified by the U.S.A. food pattern, in terms of their corresponding environmental footprints. Methods The environmental footprints of the dietary patterns studied were calculated from the dietary make-up of each dietary pattern, and specific environmental footprints of each food group. The dietary compositions were obtained from different sources, including food balance sheets and household consumption surveys. The specific environmental footprints of food groups were obtained from different available life-cycle assessments. Results The adherence of the Spanish population to the MDP has a marked impact on all the environmental footprints studied. Increasing adherence to the MDP pattern in Spain will reduce greenhouse gas emissions (72%), land use (58%) and energy consumption (52%), and to a lower extent water consumption (33%). On the other hand, the adherence to a western dietary pattern implies an increase in all these descriptors of between 12% and 72%. Conclusions The MDP is presented as not only a cultural model but also as a healthy and environmentally-friendly model, adherence to which, in Spain would have, a significant contribution to increasing the sustainability of food production and consumption systems in addition to the well-known benefits on public health.

This study evaluated the influence of different forms of heat treatment on a pre-hydrolyzed silane to improve the adhesion of phosphate monomer-based (MDP) resin cement to glass ceramic. Resin and feldspathic ceramic blocks (n=48, n=6 for bond test, n=2 for microscopy) were randomly divided into 6 groups and subject to surface treatments: G1: Hydrofluoric acid (HF) 9.6% for 20 s + Silane + MDP resin cement (Panavia F); G2: HF 9.6% for 20 s + Silane + Heat Treatment (oven) + Panavia F; G3: Silane + Heat Treatment (oven) + Panavia F; G4: HF 9.6% for 20 s + Silane + Heat Treatment (hot air) + Panavia F; G5: Silane + Heat Treatment (hot air) + Panavia F; G6: Silane + Panavia F. Microtensile bond strength (MTBS) test was performed using a universal testing machine (1 mm/min). After debonding, the substrate and adherent surfaces were analyzed using stereomicroscope and scanning electron microscope (SEM) to categorize the failure types. Data were analyzed statistically using two-way test ANOVA and Tukey's test (=0.05). Heat treatment of the silane containing MDP, with prior etching with HF (G2: 13.15 ± 0.89a; G4: 12.58 ± 1.03a) presented significantly higher bond strength values than the control group (G1: 9.16 ± 0.64b). The groups without prior etching (G3: 10.47 ± 0.70b; G5: 9.47 ± 0.32b) showed statistically similar bond strength values between them and the control group (G1). The silane application without prior etching and heat treatment resulted in the lowest mean bond strength (G6: 8.05 ± 0.37c). SEM analysis showed predominantly adhesive failures and EDS analysis showed common elements of spectra (Si, Na, Al, K, O, C) characterizing the microstructure of the glass-ceramic studied. Heat treatment of the pre-hydrolyzed silane containing MDP in an oven at 100 °C for 2 min or with hot air application at 50 ± 5 ºC for 1 min, was effective in increasing the bond strength values between the ceramic and resin cement containing MDP.

γδ T cells exhibit important functions in the pathogenesis of rheumatoid arthritis (RA). In recent years, numerous studies harnessed the γδ T cell-activating capacity of aminobiphosphonates for the treatment of malignant tumors. As (99) Tc-methylene diphosphonate ((99) Tc-MDP) has long been widely used for the treatment of RA in China with good efficacy, we are interested in whether this drug exerts its therapeutic effect on RA by modulating peripheral γδ T cells of RA patients. To investigate the effect of (99) Tc-MDP on the frequency of γδ T cells and CD4(+) CD25(+) Foxp3(+) Tregs in the peripheral blood of patients with active RA. Nineteen patients with active RA were treated with (99) Tc-MDP intravenously at a dose of 20 μg/day consecutively for 10-14 days. Before and after treatment, the main clinical and laboratory parameters for each patient were evaluated. The frequency of CD3(+) γδ(+) T cells and CD4(+) CD25(+) Foxp3(+) Tregs was detected by flow cytometry. Serum levels of interferon (IFN)-γ, tumor necrosis factor (TNF)-α, interleukin (IL)-6, IL-10 and transforming growth factor (TGF)-β were measured with enzyme-linked immunosorbent assay. After intravenous (99) Tc-MDP therapy, the frequency of peripheral CD3(+) γδ(+) T cells and CD4(+) CD25(+) Foxp3(+) Tregs were significantly elevated, paralleled with decreased serum levels of TNF-α and IL-6 and increased level of serum TGF-β. The elevation of peripheral CD3(+) γδ(+) T cells was positively correlated with increased serum TGF-β and decreased disease activity. (99) Tc-MDP may improve the activity of RA through upregulating the frequency of peripheral γδ T cells and CD4(+) CD25(+) Foxp3(+) Tregs as well as affecting the serum cytokine environment by increasing TGF-β and decreasing TNF-α and IL-6. © 2014 Asia Pacific League of Associations for Rheumatology and Wiley Publishing Asia Pty Ltd.
Altruism in Terminal Cancer Patients and Rapid Tissue Donation Program: Does the Theory Apply?

Rapid Tissue Donation (RTD) is an advancing oncology research procedure for collecting tumors, metastases, and unaffected tissue 2 to 6 hours after death. Researchers can better determine rates of progression, response to treatment, and polymorphic differences among patients. Cancer patients may inquire about posthumous body donation for research to offer a personal contribution to research; however, there are barriers to recruiting for an RTD program. Physicians must reassure the patient that their treatment options and quality of care will not be compromised due to participating in RTD. In this commentary we discuss how theories of altruism may explain cancer patients’ desire to participate in an RTD program, the ethical concerns of health care professionals and patients and the use of altruism as a recruitment strategy. We offer recommendations for examining the cultural and ethical climate of the institution prior to initiating such a program such as examining the relationship of healthcare professionals and patients, identifying ethical concerns, and examining ways to promote acceptance and buy-in across professionals, patients, and families.

Clomiphene is a synthetic estrogen agonist/antagonist used for many years to induce ovulation in anovulatory women. A recent study demonstrated that clomiphene had a protective effect against bone loss in ovariectomized aged rats. The purpose was to determine if this drug retards resorption of bone associated with disuse in rats with intact ovaries. Eleven adult (300-350g) female rats received a pedicle bone graft (disuse) in one femur with the opposite limb serving as control. Of these, 6 received weekly 10 mg injections of clomiphone (Rx). Three Rx and three untreated (unRx) were sacrificed at 6 weeks while the remainder (3more » Rx, 2 unRx) were sacrificed at 10 weeks after surgery. All received quantitative injections of MDP 24 hrs. before sacrifice and labeled microspheres (5) just prior to sacrifice. The % uptakes of MDP and S, total bone mineral (BMC) and regional BMC (RBMC) were determined. Results are expressed as a ratio of the pedicle bone to the bone from the opposite limb. At 6 weeks, MDP and S are elevated in both groups indicating that metabolic activity is elevated. The Rx group shows no change in BMC while the unRx lost 13%. At 10 weeks, MDP and S are close to one in both groups. The Rx group lost 13% BMC while the unRx lost 29%. The RBMC indicates that the early loss of mineral is located primarily in the metaphysis, a region rich in trabecular bone. These results indicate that clomiphene retards resorption of bone resulting from disuse.« less

Runtime of the Mask Data Preparation (MDP) tool is largely dependent on the hierarchy of the input layout data. In this paper, we present a technique where a hierarchical or flat input design layout or almost flat mask data can be converted into a favorable hierarchical data which can be directly used by MDP tools for fracturing. A favorable hierarchy is a hierarchy of cells where polygons within cells do not overlap with each other even if bounding boxes of cells might overlap with each other. This is an important characteristic which can be intelligently made use of by intra-polygonal operations like fracturing. Otherwise, a mask data preparation (MDP) tool has to take the responsibility for resolving overlaps among polygons, which slows down the processing and increases the data size. MDP on a favorable hierarchy will thus speed up the fracturing or re-fracturing steps and also minimize the output fractured data size, as shown through the experimental results in the paper. In the proposed technique, the favorable hierarchy is generated using a modified version of the Lempel-Ziv (LZ) coding algorithm, which was originally devised for compressing character strings. A hierarchical fracturing algorithm can be employed to work on the favorable hierarchy generated, which will utilize the property of a favorable hierarchy that polygons do not overlap with each other. Apart from the obvious runtime benefits, such a favorable hierarchy allows considerable reduction in fractured data size as most mask data formats allow representation of a hierarchy containing two levels.

Background Pattern recognition receptor NOD2 (nucleotide binding oligomerization domain 2) is well investigated in immunity, its expression and function in platelets has never been explored. Method and Results Using RT-PCR and Western blot we show that both human and mouse platelets express NOD2, and its agonist MDP induced NOD2 activation as evidenced by receptor dimerization. NOD2 activation potentiates platelet aggregation and secretion induced by low concentration of thrombin or collagen, as well as clot retraction. These potentiating effects of MDP were not seen in platelets from NOD2-deficient mice. Plasma from septic patients also potentiates platelet aggregation induced by thrombin or collagen NOD2-dependently. Using intravital microscopy, we found that MDP administration accelerated in vivo thrombosis in FeCl3-injured mesenteric arteriole thrombosis mouse model. Platelet depletion and transfusion experiments confirmed that NOD2 from platelets contributes to the in vivo thrombosis in mice. NOD2 activation also accelerates platelet-dependent hemostasis. We further found that platelets express RIP2 (receptor-interacting protein 2), and provided evidences suggesting that MAPK and NO/sGC/cGMP/PGK pathways downstream of RIP2 mediate the role of NOD2 in platelets. Finally, MDP stimulates proinflammatory cytokine IL-1β maturation and accumulation in human and mouse platelets NOD2-dependently. Conclusions NOD2 is expressed in platelets and functions in platelet activation and arterial thrombosis, possibly during infection. To our knowledge, this is the first study on NOD-like receptors in platelets which links thrombotic events to inflammation. PMID:25825396

Many organisms vary their behaviour in response to environmental change. In stressful habitats motile organisms often exhibit behavioural patterns that are consistent with stress-minimizing strategies. In the present study we analysed the proportions of individuals with strong site fidelity and distances travelled by “unfaithful” individuals from their home scar at different temporal and spatial scales in the intertidal gastropod Siphonaria lessoni. We also assessed the behavioural response of S. lessoni to biological pressures such as conspecific population density and food availability (assessed by measures of chlorophyll a). The experiments were carried out in the arid climate of Patagonia on the rocky intertidal of Las Grutas (LG), and in the humid climate of The Pampas on the rocky intertidal of Mar del Plata (MDP) Argentina. At each site, shells of five hundred animals were marked with epoxy paint. Movement was measured as distance to a reference point after periods of one, five and ten days. Our results showed a positive relationship between food availability, site fidelity and distance to home scar for almost all observation days, but no relationship between population density and behavioural variables. Limpets in LG were more “faithful” than in MDP. Unfaithful limpets had the same mean displacement for all days and seasons except for Spring day-1 where MDP was higher than in LG and in Autumn day-10 where MDP was smaller than LG. The present results thus show differential response behaviour in intertidal limpets probably driven by the environmental conditions in which they live.

The diversity of the nation is one of society's greatest assets, but this feature is overshadowed by the disproportionate burden of disease that exists among America's minorities. Evidence of the disparate health status has been documented in low life expectancy, cancer, diabetes, cardiovascular, and kidney disease as well as a plethora of disorders that necessitate organ transplantation. Many minorities have been reluctant to register to become organ donors. This circumstance can be alleviated by educating the public regarding the necessity of organ transplantation. We have developed a "unique" collaborative outreach program designed to promote acceptance of organ donation in African-Americans (AAs). Our outreach curriculum at Bureau of Motor Vehicles (BMV) has resulted in increased registrations and awareness regarding the need and positive perceptions toward donation. We developed a culturally sensitive outreach program: cultural sensitivity indicates how culture has the ability to influence communication between patients and health providers. An "Outreach Promotional Contest" was strategically targeted toward 28 Ohio BMVs to promote and assist in an outreach educational program regarding organ donation/registry. The consequence/results has been an increase of 3.4% in the BMV locations. The one BMV, with the highest increase was attended predominantly by AAs which moreover, won first place in the contest (6.425%; P < .05). To increase the number of people willing to register, we believe that both community education regarding the need and importance, as well as culturally sensitive promotion of organ donation, is the best way to increase organ donor registries particularly among minority populations.
Ethical issues surrounding the use of images from donated cadavers in the anatomical sciences.
Cornwall, Jon; Callahan, David; Wee, Richman
2016-01-01
Body donor programs rely on the generosity and trust of the public to facilitate the provision of cadaver resources for anatomical education and research. The uptake and adoption of emerging technologies, including those allowing the acquisition and distribution of images, are becoming more widespread, including within anatomical science education. Images of cadavers are useful for research and education, and their supply and distribution have commercial potential for textbooks and online education. It is unclear whether the utilization of images of donated cadavers are congruent with donor expectations, societal norms and boundaries of established public understanding. Presently, no global "best practices" or standards exist, nor is there a common model requiring specific image-related consent from body donors. As ongoing success of body donation programs relies upon the ethical and institutional governance of body utilization to maintain trust and a positive relationship with potential donors and the community, discussions considering the potential impact of image misuse are important. This paper discusses the subject of images of donated cadavers, commenting on images in non-specific use, education, research, and commercial applications. It explores the role and significance of such images in the context of anatomical science and society, and discusses how misuse - including unconsented use - of images has the potential to affect donor program success, suggesting that informed consent is currently necessary for all images arising from donated cadavers. Its purpose is to encourage discussion to guide responsible utilization of cadaver images, while protecting the interests of body donors and the public. © 2015 Wiley Periodicals, Inc.

Unambiguous investigation of condensed tannin (CT) structure-activity relationships in biological systems requires well-characterized, high-purity CTs. Sephadex LH-20 and Toyopearl HW-50F resins were compared for separating CTs from acetone/water extracts, and column fractions analyzed for flavan-3-ol subunits, mean degree of polymerization (mDP), and purity. Toyopearl HW-50F generated fractions with higher mDP values and better separation of procyanidins (PC) and prodelphinidins (PD) but required a prepurification step, needed more time for large scale purifications, and gave poorer recoveries. Therefore, two gradient elution schemes were developed for CT purification on Sephadex LH-20 providing 146-2000 mg/fraction. Fractions were analyzed by thiolysis and NMR spectroscopy. In general, PC/PD ratios decreased and mDP increased during elution. 1 H NMR spectroscopy served as a rapid screening tool to qualitatively determine CT enrichment and carbohydrate impurities present, guiding fractionation toward repurification or 1 H- 13 C HSQC NMR spectroscopy and thiolysis. These protocols provide options for preparing highly pure CT samples.

Hawari, Ayman I.; Venneri, Francesco
The objective of this project is to perform feasibility assessment and technology gap analysis and establish a development roadmap for an innovative and highly compact Micro Modular Reactor (MMR) concept that integrates power production, power conversion and electricity generation in a single unit. The MMR is envisioned to use fully ceramic micro-encapsulated (FCM) fuel, a particularly robust form of TRISO fuel, and to be gas-cooled (e.g., He or CO 2) and capable of generating power in the range of 10 to 40 MW-thermal. It is designed to be absolutely melt-down proof (MDP) under all circumstances including complete loss of coolantmore » scenarios with no possible release of radioactive material, to be factory produced, to have a cycle length of greater than 20 years, and to be highly proliferation resistant. In addition, it will be transportable, retrievable and suitable for use in remote areas. As such, the MDP-MMR will represent a versatile reactor concept that is suitable for use in various applications including electricity generation, process heat utilization and propulsion.« less

There is a worldwide shortage of organs for transplantation. It has been shown that the attitude of healthcare professionals can improve the rates of organ donation, and that educational programs aimed at improving both attitudes and knowledge base of professionals can have positive outcomes. Although there has been research carried out on this…
[Marketing in the world of blood donation].
Daigneault, Sylvie
2007-05-01
Public and non-profit organizations have long debated how marketing concepts and management styles apply to their sector of activity as they are largely derived from principles of consumerism and economic decision-making proper to the private sector. The arrival of marketing in the world of blood donation is no exception. The purpose of this article is to illustrate concretely how marketing techniques can contribute in achieving the objectives of a blood donation program: a marketing model that is adapted to the realities of blood donation in Quebec. Although types of marketing are as varied as the fields they are used in, the major marketing activities of this program fall under positioning, operational or relationship marketing. The process is presented in the form of a cycle that includes four major phases containing all marketing functions, that is, raising public awareness, acquiring a clientele, client retention and loyalty building, and establishing the relationship. Finally, the information and effective management of information are at the heart of the marketing process. In fact, research, understanding our customers and their expectations, and measuring our performance are essential for the success of any marketing initiative.

A promising strategy for increasing living donor kidney transplant (LDKT) rates is improving education about living donation for both prospective kidney transplant recipients and living donors to help overcome the proven knowledge, psychological, and socioeconomic barriers to LDKT. A recent Consensus Conference on Best Practices in Live Kidney Donation recommended that comprehensive LDKT education be made available to patients at all stages of chronic kidney disease (CKD). However, in considering how to implement this recommendation across different healthcare learning environments, the current lack of available guidance regarding how to design, deliver, and measure the efficacy of LDKT education programs is notable. In the current article, we provide an overview of how one behavior change theory, the Transtheoretical Model of Behavior Change, can guide the delivery of LDKT education for patients at various stages of CKD and readiness for LDKT. We also discuss the importance of creating educational programs for both potential kidney transplant recipients and living donors, and identify key priorities for educational research to reduce racial disparities in LDKT and increase LDKT rates.

Organ donation from brain dead patients is a contentious issue in Korea within the cultural context of Confucian beliefs. Each year thousands of patients wait for organ donation note poor donation rates and importance of nurses in identifying potential donors. It is therefore important to identify knowledge levels and attitudes towards organ donation from brain dead patients of nursing students as future health workers. Using a 38-item instrument previously developed by the researchers, 292 undergraduate students in a Korean nursing college were surveyed in 2003 in Korea (response rate 92%). Validity and reliability of the instrument was demonstrated using a multiple analytical approach. A lack of knowledge regarding diagnostic tests and co-morbid factors of brain death were noted among students. Their attitudes toward organ donation were somewhat mixed and ambiguous, but overall they were positive and willing to be a potential donor in the future. While this study identified that an effective educational program is necessary for nursing students in Korea to improve their knowledge of brain death and organ donation, further research is also required to verify these single-site findings and improve the generalisability of results.

Successes in organ donation and transplantation programs are directly evidence-based education. Transplant Procurement Management (TPM) is an international educational project on organ donation and transplantation. Our purpose was to evaluate the TPM educational project. We compared the data of 17 years of experience, strategies, and methods. We retrospectively performed a descriptive analysis of all educational activities developed between 1991 and 2008. We identified 7 crucial points. (1) In 1991, TPM was started under the auspices of the University of Barcelona (UB) and the National Spanish Transplant Organization (ONT; national training, face-to-face). (2) In 1994, TPM became international (international advanced training and country-based). (3) Since 1997 in Italy and 2006 in France, national training courses were organized adapting the same methodologies as the advanced international TPM courses. TPM also implemented short (1-3 days) introductory courses worldwide. (4) In 2002, the e-learning platform program was launched to facilitate the education of professionals. (5) In 2005, an international master's degree was created at UB under the Life-Long Learning Institute (IL3). (6) In 2006, the courses were expanded to include pregraduate health science faculties with the International Project on Education and Research in Donation at University of Barcelona (PIERDUB). (7) In 2007, the European-funded European Training Program on Organ Donation (ETPOD) project was started. Currently, TPM offers face-to-face, e-learning, and blended international courses. As of 2008, TPM has trained 6498 professionals in 89 countries on 5 continents. TPM has impacted positively on the various essential levels in the process of organ donation and transplantation, with lifelong follow-up and an international network through the capacity to adapt to specific country needs as well as continuous quality improvement thanks to the collaboration of expert teachers and consultants.

In 2011, the European Directorate for the Quality of Medicines & Healthcare of the Council of Europe launched a 3-year collaborative project to address the organ shortage and improve access to transplant health services in Council of Europe member states in the Black Sea area (Armenia, Azerbaijan, Bulgaria, Georgia, Moldova, Romania, Turkey, Ukraine, and the Russian Federation) through the development of safe and ethical donation and transplantation programs. Support the development of donation and transplantation programs through close interstate cooperation between national health organizations and relevant stakeholders. Several work packages (WP) were established: WP1, project coordination (European Directorate for the Quality of Medicines & Healthcare); WP2, development and implementation of an effective legislative and financial framework (Czech Republic and France); WP3, establishment of National Transplant Authorities (Italy and Portugal); and WP4, clinical practices (DTI Foundation). Data collection, surveys, and expert visits allowed for the collection of first-hand information from each participant country at national, regional, and hospital levels. Data analysis showed the positive impact of the project represented by a tendency to increase the total donation rates (per million people) in the participant countries (2011 vs 2013): Azerbaijan, +7.3; Armenia, -0.7; Georgia, +3.3; Bulgaria, +0.9; Moldova, +2.5; Ukraine:, +0.8; Romania, +2.3; and Turkey, +2.7. Increases in total donation rates are the result of a number of initiatives in the Black Sea area, including the stepwise implementation of legislative, organizational and institutional country-specific recommendations tailored by the CoE, efforts of the respective Ministries of Health in each country and synergism with other European projects in the region. These countries should invest further in implementing the recommendations that emerged from this project to improve their organ donation and transplantation programs and progress toward self-sufficiency.

Sports nuclear medicine. Bone imaging for lower extremity pain in athletes
DOE Office of Scientific and Technical Information (OSTI.GOV)
Brill, D.R.
Increased participation in sports by the general public has led to an increase in sports-induced injuries, including stress fractures, shin splints, arthritis, and a host of musculotendinous maladies. Bone scintigraphy with Tc-99m MDP has been used with increasing frequency in detecting stress fractures, but this study can miss certain important conditions and detect other lesions of lesser clinical significance. This paper demonstrates the spectrum of findings on bone scanning in nonacute sports trauma and offers suggestions for the optimal use of Tc-99m MDP for detecting the causes of lower extremity pain in athletes.
Diagnosis of malignant change in Paget's disease by Tl-201.
Colarinha, P; Fonseca, A T; Salgado, L; Vieira, M R
1996-04-01
Scintigraphy using Tc-99m MDP and Tl-201 was performed in a patient with polyostotic Paget's disease and sarcomatous degeneration in the right iliac bone. Tc-99m MDP imaging showed abnormal uptake in both types of lesions. Tl-201 imaging showed increased uptake in the sarcomatous lesion and absent uptake in pagetic lesions. This result supports the idea that Tl-201 scintigraphy may have a potential role to play in the differentiation of Paget's disease from malignancy. To the authors' knowledge, Tl-201 has never been reported for the detection of sarcomatous change of pagetic bone.

Recent efforts to recruit blood and organ donors have only marginally improved demographic disparities in willingness to donate. Few studies have examined which factors are most important in explaining race and gender disparities in willingness to donate. To assess race and gender differences in willingness to donate blood and cadaveric organs, and to determine the extent to which several factors (including sociodemographic characteristics and attitudes about religion and mistrust of hospitals) might explain differences in willingness to donate. Cross-sectional telephone survey of Maryland households contacted via random-digit dialing. Past blood donation, organ-donor status on driver's license, and measures of medical mistrust and religious and spiritual salience. Persons age 18 to 75 living in the Baltimore, Maryland metropolitan area. Of 385 respondents (84% of randomized households), 114 were black females, 46 were black males, 110 were white females, and 69 were white males. Before adjustment, black females were least willing to donate blood (41%), and black males were least willing to become cadaveric donors (19%) among all race-gender groups. Adjustment for respondent concerns about mistrust of hospitals and discrimination in hospitals explained most differences in willingness to donate blood, whereas adjustment for respondents' beliefs regarding the importance of spirituality and religion explained most differences in willingness to donate cadaveric organs. Both race and gender are important identifiers of those less willing to donate. To maximize efficiency, donor recruitment efforts should focus on race-gender groups with lowest levels of willingness. Potential donor concerns regarding mistrust in hospitals and religion/spirituality may serve as important issues to address when developing programs to improve donation rates.

The purpose of this study was to identify the knowledge, attitude, educational needs, and will of nursing students on organ donation from brain-dead donors. Data were collected by using a 40-item questionnaire to measure knowledge, attitude, educational needs, and will for organ donation of 215 nursing college students in one university in Dangjin city from May 11 to May 31, 2017. The data were analyzed using SPSS 22 program (Data Solution Inc, Seoul). In the general characteristics, 85.1% of the subjects did not receive education on donation, and 99.5% of the subjects responded that education is needed. The desired methods of education were special lecture in school (55.3%), "webtoons" on the Internet (19.5%), formal curriculum (15.8%). Points to improve to increase brain-death organ transplantation and donation included "active publicity through pan-national campaign activities" (56.3%), "respecting prior consent from brain-dead donors" (21.9%), and "encouragement and increased support for organ donors" (12.1%). There was a significant difference in knowledge according to will for organ donation (t = 3.29, P = .001) and consent to brain-death organ donation in family members (t = 3.29, P = .001). There was a statistically significant positive correlation between attitude and knowledge of the subjects regarding brain-death organ donation. The knowledge, attitude, educational need, and will for organ donation of nursing students revealed in this study will be used as basic data to provide systematic transplant education including contents about organ transplantation in the regular nursing curriculum in the future. It will contribute to the activation of organ donation. Copyright © 2018 Elsevier Inc. All rights reserved.

Lactation and breast milk can hold great value and meaning for grieving mothers who have experienced a recent death of an infant. Donation to a human milk bank (HMB) as an alternative to discarding breast milk is one means of respecting the value of breast milk. There is little research, national policy discussion, or organizational representation in Australia on the subject of breast milk donation after infant death. On 29 November 2013 the Mercy Hospital for Women in Melbourne, Australia hosted Australia's first National Stakeholder Meeting (NSM) on the topic of milk donation after neonatal death. The NSM drew together representatives from Australian HMBs, neonatal intensive care units (NICUs) currently using donor human milk, and Australia's chief NICU parent support organization. The NSM was video-recorded and transcribed, and analyzed thematically by researchers. This article reports the seven dominant themes discussed by stakeholders during the NSM: the spectrum of women's lactation and donation experiences after infant death; the roles of the HMB and NICU in meeting the needs of the bereaved donor; how bereaved mothers' lactation autonomy may interface with a HMB's donation guidelines; how milk donation may be discussed with bereaved mothers; the variation between four categories of milk donation after neonatal death; the impact of limited resources and few HMBs on providing donation programs for bereaved mothers in Australia. This article provides evidence from researchers and practitioners that can assist HMB staff in refining their bank's policy on milk donation after infant death, and provides national policy makers with key considerations to support lactation, human milk banking, and bereavement services nation-wide.

Nowadays, ICU nurses play a significant role in the care of brain-dead patients and their families. Therefore, their knowledge, attitude and practice towards this issue are extremely important to the success of organ donation. To assess ICU nurses' knowledge, attitude and practice towards their role in the organ donation process from brain-dead patients and factors influencing it in Iran. In a cross-sectional analytical study, 90 ICU nurses working in Ghaem and Emam Reza Hospitals affiliated to Mashhad University of Medical Sciences were selected through a stratified random sampling. Data were collected from the participants by a questionnaire included demographic information, and factors influencing the nurses knowledge, attitude, and practice towards their roles in the organ donation process. 90 nurses participated in this study. 70% of the research subjects had spoken with their own families about organ donation; 20% had organ donation cards. The mean±SD score of nurses' knowledge was 49.13±9.6, attitude 21.49±14.32, and practice was 3.66±6.04. 80% of nurses had a mean knowledge about their roles in the organ donation process; 82% agreed with their roles in this process, and 97% showed weak practice in this regard. Nurses did not have adequate knowledge, attitude, and practice towards their role in organ donation process. It is suggested to include nursing courses on the organ donation process and organ transplantation as well as educational programs to acquaint nurses with their roles in the organ donation process.

This article studies multicenter coordination of unspecified living kidney donation and transplantation across the blood-type barrier in kidney exchange. Important questions are whether such coordination should use domino paired donation or non simultaneous extended altruistic donor chains, what the length of the segments in such chains should be, when they should be terminated, and how much time should be allowed between matching rounds. Furthermore, it is controversial whether the different modalities should be coordinated centrally or locally and independently. Kidney exchange policies are simulated using actual data from the Dutch national kidney exchange program. Sensitivity analysis is performed on the composition of the population, the time unspecified and bridge donors wait before donating to the wait list, the time between matching rounds, and donor renege rates. Central coordination of unspecified donation and transplantation across the blood-type barrier can increase transplants by 10% (PG0.001). Especially highly sensitized and blood type O patients benefit. Sufficient time between matching rounds is essential: three-monthly exchanges result in 31% more transplants than weekly exchanges. Benefits of non simultaneous extended altruistic donor chains are limited in case of low numbers of highly sensitized patients and sufficient unspecified donors. Chains are best terminated when no further segment is part of an optimal exchange within 3 months. There is clear synergy in the central coordination of both unspecified donation and transplantation across the blood-type barrier in kidney exchange. The best configuration of a national program depends on the composition of the patient Y donor population.

This study explores the effects of tissue requesters' relational, persuasive, and nonverbal communication on families' final donation decisions. One thousand sixteen (N = 1,016) requests for tissue donation were audiotaped and analyzed using the Siminoff Communication Content and Affect Program, a computer application specifically designed to code and assist with the quantitative analysis of communication data. This study supports the important role of communication strategies in health-related decision making. Families were more likely to consent to tissue donation when confirmational messages (e.g., messages that expressed validation or acceptance) or persuasive tactics such as credibility, altruism, or esteem were used during donation discussions. Consent was also more likely when family members exhibited nonverbal immediacy or disclosed private information about themselves or the patient. The results of a hierarchical log-linear regression revealed that the use of relational communication during requests directly predicted family consent. The results provide information about surrogate decision making in end-of-life situations and may be used to guide future practice in obtaining family consent to tissue donation.

Historically, living kidney donation has been justified in part by our belief that living donors face minimal risks of subsequent disease. Recent research has brought that presumption into question, particularly for younger donors including parents. In light of this finding, we re-examine many of the traditional arguments both for and against the practice of parental living kidney donation. We then propose an alternative framework in which the burden of having a child with end-stage kidney disease can be considered as an illness experienced by the potential donor parent. We believe this allows a more straightforward, as well as more accurate, assessment of the risks and benefits of donation for the potential parental donor. This assessment might then be used to best inform the decision whether or not to proceed with kidney donation using a shared decision-making model, while reflecting the appropriate ethical roles of both the potential donor and the transplantation program. © 2018 John Wiley & Sons A/S.

A national minority transplant program for increasing donation rates.
Callender, C; Burston, B; Yeager, C; Miles, P
1997-01-01
Since 1982, our group efforts demonstrated statistically significant improvements in minority donation rates which have applicability to all minority populations. As we continue to reach out to the various ethnic communities, we must listen to the needs of the community understanding that all ethnic communities have various beliefs and cultural barriers that will need to be addressed. For instance, the African-American population revealed the previously mentioned five obstacles to donation. The Hispanic population has revealed relatively the same fears to donation as the African-American population. In addition, the tribes within the Native-American population each have their own belief systems which will have to be addressed appropriately. The fears and obstacles toward donation within the Asians and Pacific Islanders and the Alaska Native groups are being defined. However, initial research reveals that all of the minority groups have very similar, if not the same, fears that were identified with the initial focus group in 1978. This simple methodology that has been established can ultimately help achieve the overall desired goal--an increase in minority donation rates.

The biggest obstacle to overcome for routine treatment of various pathologies with fresh osteochondral allograft is the availability of tissue for transplantation. Large fresh osteochondral allografts are usually harvested from organ donors, but in contrast to organs, tissues can be procured after cardiac arrest. Medical staff as well the general public are much less aware of the possibilities and requirements of tissue donation compared to organ donation. This review aims to highlight the current situation of organ and tissue donation in Europe and to raise this much needed awareness. For this research, PubMed database was scanned using the terms "tissue/organ donation", "bone donation/transplantation", "cartilage transplantation/allografts" and "osteochrondral allografts". Relatives of potential donors are often not approached because physicians and nurses do not feel sufficiently prepared for this task and, thus, are reluctant to address this topic. Different options could alleviate the pressure medical staff is feeling. Furthermore, there are different factors influencing consent that can be addressed to increase donation rates. Currently, a lot of potential concerning musculoskeletal tissue grafts remains unused. Most importantly, families should be encouraged to speak about their potenzial will to donate and educational programs should be established to increase trust in organ and tissue donation and the allocation system and to increase knowledge about the importance of transplantation medicine. But joined efforts of different parts of the medical systems and different organizations involved in tissue transplantation should improve the situation for patients waiting for much needed transplants.

The need for suitable organs for transplantation is especially pronounced in minority populations such as Hispanic Americans owing to disproportionately high rates of diabetes mellitus and kidney disease. Considerable barriers exist for Hispanic Americans consent to donation, resulting in significantly lower donation rates compared with white individuals. To investigate the effect of an aggressive outreach intervention during a 5-year period aimed at improving organ donation rates among Hispanic Americans. Prospective longitudinal observation study of organ donors treated at a major metropolitan level I trauma center. The center provides most of the medical care to the 4 Southern California neighborhoods with a high percentage of Hispanic Americans that were included in the study. Television and radio media campaigns and culturally sensitive educational programs implemented at high schools, churches, and medical clinics in the target neighborhoods. Consent rate for organ donation recorded during the study. Outreach interventions started in 2007 and were completed by 2012. Of 268 potential donors, 155 total donors (106 Hispanic Americans) provided consent during this time. A significant increase in consent rate was noted among Hispanic Americans, from 56% in 2005 to 83%in 2011 (P = .004); this increase was not evident in the population that was not Hispanic (67%in 2005 and 79% in 2011; P = .21). Aggressive outreach programs can reduce the disparity between organ supply and demand by improving the consent rate among the target group.

To compare qualitative vs quantitative results of Single Photon Emission Computerised Tomography (SPECT), calculated from percentage of 99m Tc-MDP (methylene diphosphonate) uptake, in condyles of patients with a presumptive clinical diagnosis of condylar hyperplasia. A retrospective, descriptive study was conducted on the 99m Tc-MDP SPECT bone scintigraphy reports from 51 patients, with clinical impression of facial asymmetry related to condylar hyperplasia referred by their specialist in orthodontics or maxillofacial surgery, to a nuclear medicine department in order to take this type of test. Quantitative data from 99m Tc-MDP condylar uptake of each were obtained and compared with qualitative image interpretation reported by a nuclear medicine expert. The concordances between the 51 qualitative and quantitative reports results was established. The total sample included 32 women (63%) and 19 men (37%). The patient age range was 13-45 years (21±8 years). According to qualitative reports, 19 patients were positive for right side condylar hyperplasia, 12 for left side condylar hyperplasia, with 8 bilateral, and 12 negative. The quantitative reports diagnosed 16 positives for right side condylar hyperplasia, 10 for left side condylar hyperplasia, and 25 negatives. Nuclear medicine images are an important diagnostic tool, but the qualitative interpretation of the images is not as reliable as the quantitative calculation. The agreement between the two types of report is low (39.2%, Kappa=0.13; P>.2). The main limitation of quantitative reports is that they do not register bilateral condylar hyperplasia cases.

Minority carrier lifetime (lifetime) measurements are performed on corona-charged silicon wafers by means of Microwave Detected Photoconductivity (MDP). The corona charge is deposited on the front and back sides of oxidized wafers in order to adjust accumulation conditions. Once accumulation is established, interface recombination is suppressed and bulk lifetimes are obtained. Neither contacts nor non-CMOS compatible preparation techniques are required in order to achieve accumulation conditions, which makes the method ideally suited for inline characterization. The novel approach, termed ChargedMDP (CMDP), is used to investigate neutron transmutation doped (NTD) float zone silicon with resistivities ranging from 6.0 to 8.2 kΩ cm. The bulk properties of 150 mm NTD wafers are analyzed in detail by performing measurements of the carrier lifetime and the steady-state photoconductivity at various injection levels. The results are compared with MDP measurements of uncharged wafers as well as to the established charged microwave detected Photoconductance Decay (charge-PCD) method. Besides analyzing whole wafers, CMDP measurements are performed on oxide test-structures on a patterned wafer. Finally, the oxide properties are characterized by means of charge-PCD as well as capacitance-voltage measurements. With CMDP, average bulk lifetimes up to 33.1 ms are measured, whereby significant variations are observed among wafers, which are produced out of the same ingot but oxidized in different furnaces. The observed lifetime variations are assumed to be caused by contaminations, which are introduced during the oxidation process. The results obtained by CMDP were neither accessible by means of conventional MDP measurements of uncharged wafers nor with the established charge-PCD method.

Predisposition to food allergies may reflect a type 2 immune response (IR) bias in neonates due to the intrauterine environment required to maintain pregnancy. The hygiene hypothesis states that lack of early environmental stimulus leading to inappropriate development and bias in IR may also contribute. Here, the ability of heat-killed Escherichia coli, lipopolysaccharide (LPS), or muramyl dipeptide (MDP) to alter IR bias and subsequent allergic response in neonatal pigs was investigated. Three groups of three litters of pigs (12 pigs/litter) were given intramuscular injections of E. coli, LPS, MDP, or phosphate-buffered saline (PBS) (control) and subsequently sensitized to the egg white allergen ovomucoid using an established protocol. To evaluate change in IR bias, immunoglobulin isotype-associated antibody activity (AbA), concentrations of type 1 and 2 and proinflammatory cytokines released from mitogen-stimulated blood mononuclear cells, and the percentage of T-regulatory cells (T-regs) in blood were measured. Clinical signs of allergy were assessed after oral challenge with egg white. The greatest effect on IR bias was observed in MDP-treated pigs, which had a type 2-biased phenotype by isotype-specific AbA, cytokine production, and a low proportion of T-regs. LPS-treated pigs had decreased type 1- and type 2-associated AbA. E. coli-treated pigs displayed increased response to Ovm as AbA and had more balanced cytokine profiles, as well as the highest proportion of T-regs. Accordingly, pigs treated with MDP were more susceptible to allergy than PBS controls, while pigs treated with LPS were less susceptible. Treatment with E. coli did not significantly alter the frequency of clinical signs.

There is currently an organ shortage crisis in the United States. This paper analyzes the magnitude of the problem, the organ procurement programs in other developed countries as compared to the US, and discusses the changes that can be made to address this problem. With the opt-in or explicit-consent method currently practiced in the US, less that one third of the population consents to organ donation. In order to narrow the gap between the demand and supply of organs, steps need to be taken to improve the organ procurement infrastructure. The public needs to be educated about the dire need, the benefits and risks in organ donation, and living vs. deceased donation.

Establishment of a national kidney paired donation (KPD) program represents a unique achievement in Canada's provincially organized health care system. Key factors enabling program implementation included consultation with international experts, formation of a unique organization with a mandate to facilitate interprovincial collaboration, and the volunteer efforts of members of the Canadian transplant community to overcome a variety of logistical barriers. As of December 2013, the program had facilitated 240 transplantations including 10% with Calculated panel reactive antibody (cPRA) ≥97%. Unique features of the Canadian KPD program include participation of n = 55 nondirected donors, performance of only donor specific antibody negative transplants, the requirement for donor travel, and nonuse of bridge donors. The national KPD program has helped maintain the volume of living kidney donor transplants in Canada over the past 5 years and serves as a model of inter-provincial collaboration to improve the delivery of health care to Canadians.

In an era where there is a shortage of lungs for transplantation is increased utilization of lungs from donation after circulatory death (DCD) donors. We review the reports of 11 controlled and 1 uncontrolled DCD programs focusing on donor criteria, procedural criteria, graft assessment, and preservation techniques including the use of ex vivo lung perfusion. We have formulated conclusions and recommendations for each of these areas, which were presented at the 6th International Conference on Organ Donation. A table of recommendations, the grade of recommendations, and references are provided. © 2015 Steunstichting ESOT.

Blood donation has remained a challenge in developing countries, like Ethiopia. In Ethiopia there is a high reliance on family surrogate and waged blood donors which carries an attendant increased risk of transfusion transmissible infection. Health workers are expected to practice blood donation so as to create a good image to the public. A study on blood donation behavior may improve successful implementation of the blood donation programs. An institution based cross-sectional study was deployed from January to June 2015. An aggregate of 427 health workers were included in the study by using simple random sampling technique. Data were collected by using pre tested and structured questionnaire via self-administrated method. Descriptive and summary statistics were employed. Bivariate and multiple logistic regressions were computed. Odds ratios and their 95% confidence intervals were calculated to determine the level of significance. A total of 427 participants were included in the final analysis (response rate = 100%). Among these participants, 33.2% of them practice blood donation. Age above 25 years [AOR = 1.8 (95% CI 1.1, 3.0)], health professionals' knowledge of blood donation [AOR = 1.9 (95% CI 1.1, 3.1)], health professionals' attitude towards blood donation [AOR = 3.0, 95% CI 1. 8, 4.9)], and the presence of family members or relatives who received blood [AOR = 5.4, 95% CI 3.7, 8.7)] were significantly and independently associated with blood donation behavior of health professionals. Blood donation practice of health professionals in this study was found to be low as compared to other studies conducted in developing countries. Health professionals' knowledge, attitude, age and the presence of family members or relatives who received blood before were independently associated with blood donation practice. Thus, awareness has to be created for health professionals to improve blood donation practices.

Background: For many of the end-stage organ diseases, organ transplantation is the most preferred treatment. The need for the organ transplantation is higher than the availability. For the transplantation program to be successful, awareness regarding organ donation is needed and people must have a positive attitude toward donating organs. Aim: This study aims to assess the awareness and attitudes regarding organ donation among the rural population and to evaluate the sociodemographic factors associated with their awareness. Subjects and Methods: This community-based cross-sectional study was conducted among 360 people living in 4 villages of Puducherry. Face-to-face interviews were carried out using pretested questionnaire, which included the sociodemographic data. Data were entered into Excel and analyzed using Statistical Package for Social Sciences. Results: Of 360 participants, 88% (317/360) were aware of organ donation. Among these 317 participants, awareness was highest in the age group 18–30 years 98.8% (87/88), male 91% (147/161), higher secondary and above 100% (58/58), and Class 1 socioeconomic status 92% (13/14). Source of awareness about organ donation was primarily through media 83% (263/317). The majority of the participants 88% (281/317) felt that the purpose of organ donation was to save life. Most of the participants 91% (290/317) said that all healthy adults are eligible organ donors and 87% (275/317) of the participants said that monetary benefits could not be accepted for organ donation. Most of the participants 70% (223/317) were willing to donate their organs after death. Among the participants who refused to donate their organs, family refusal 57% (25/44) was the most common reason. Conclusion: This study shows that there is a high level of awareness about organ donation among rural people and most of the participants are willing to donate their organs. PMID:28503345

Understanding blood donor motivations is crucial to improving effectiveness of donor recruitment and retention programs. Data from a 1998 survey of 92,581 U.S. blood donors were used to evaluate factors influencing the decision to donate in various demographic groups. Data were weighted to adjust for response and sample design. Of 52,650 respondents, 45,588 gave whole-blood (WB) donations. Among all demographic groups, the major reasons to donate were altruism (75-87%) and awareness of the need for blood (34-43%). Except for first-time donors and those

BACKGROUND Organ transplantation is one of the most critical topics in medical ethics that is commonplace in various countries. This study aimed to evaluate the knowledge and the ethical issues surrounding organ transplantation and organ donation among healthcare personnel in Tehran, Iran. MATERIAL AND METHODS In a cross-sectional study performed on 450 healthcare personnel, self-administered questionnaires were used to derive data from individuals. Among the 450 health personnel who received the questionnaires, 377 completed their questionnaires (83.77%). RESULTS The willingness and unwillingness to donate organs among individuals were 47.48% (n=179) and 52.51% (n=198), respectively. Among the individuals who signed the organ donation card, 96.5% (n=55) were willing to donate their organs and 3.5% (n=2) were unwilling to donate their organs. Most of the individuals that were willing (48.34%; n=175) and unwilling (51.66%; n=187) to donate their organs claimed religious support for organ donation (P=0.00). Out of these people, 110 willing people (67.48%) and 53 (32.52%) unwilling people were familiar with the idea of brain death. The individuals who selected cadavers (67.64%; n=255) and brain death (24.4%; n=92) were chosen as the best candidates for organ donation. Most individuals believed that young patients (n=123; 32.62%) and people who had not already had organ transplants (n=90; 23.87%) should be the preferred recipients of organs. Most individuals had learned about organ transplantation from television (30.24%; n=114), newspapers (23.61%; n=89), and the radio (19.89%; n=75). CONCLUSIONS In conclusion, there is a need for more educational programs for the improvement of knowledge and ethical consideration with regard to organ transplantation and organ donation among healthcare personnel.

Background: Nowadays, ICU nurses play a significant role in the care of brain-dead patients and their families. Therefore, their knowledge, attitude and practice towards this issue are extremely important to the success of organ donation. Objective: To assess ICU nurses’ knowledge, attitude and practice towards their role in the organ donation process from brain-dead patients and factors influencing it in Iran. Methods: In a cross-sectional analytical study, 90 ICU nurses working in Ghaem and Emam Reza Hospitals affiliated to Mashhad University of Medical Sciences were selected through a stratified random sampling. Data were collected from the participants by a questionnaire included demographic information, and factors influencing the nurses knowledge, attitude, and practice towards their roles in the organ donation process. Results: 90 nurses participated in this study. 70% of the research subjects had spoken with their own families about organ donation; 20% had organ donation cards. The mean±SD score of nurses’ knowledge was 49.13±9.6, attitude 21.49±14.32, and practice was 3.66±6.04. 80% of nurses had a mean knowledge about their roles in the organ donation process; 82% agreed with their roles in this process, and 97% showed weak practice in this regard. Conclusion: Nurses did not have adequate knowledge, attitude, and practice towards their role in organ donation process. It is suggested to include nursing courses on the organ donation process and organ transplantation as well as educational programs to acquaint nurses with their roles in the organ donation process.

Umbilical cord blood: a guide for primary care physicians.
Martin, Paul L; Kurtzberg, Joanne; Hesse, Brett
2011-09-15
Umbilical cord blood stem cell transplants are used to treat a variety of oncologic, genetic, hematologic, and immunodeficiency disorders. Physicians have an important role in educating, counseling, and offering umbilical cord blood donation and storage options to patients. Parents may donate their infant's cord blood to a public bank, pay to store it in a private bank, or have it discarded. The federal government and many state governments have passed laws and issued regulations regarding umbilical cord blood, and some states require physicians to discuss cord blood options with pregnant women. Five prominent medical organizations have published recommendations about cord blood donation and storage. Current guidelines recommend donation of umbilical cord blood to public banks when possible, or storage through the Related Donor Cord Blood Program when a sibling has a disease that may require a stem cell transplant. Experts do not currently recommend private banking for unidentified possible future use. Step-by-step guidance and electronic resources are available to physicians whose patients are considering saving or donating their infant's umbilical cord blood.

Ethical aspects of organ donation activities.

Renal transplant remains the treatment of choice for patients with end-stage renal disease. Human organs can be harvested from 2 main sources: living and deceased donors. Preference should be given to deceased-donor transplants since they represent the only source of organs for several nonrenal solid-organ transplants and the only modality where there is no risk to the donor. Unfortunately, even the most well-developed deceased-donor program (eg, the Spanish program) can barely cover 50% of its waiting list because the demand for deceased-donor organs far exceeds supply. The success of transplant surgery has created a waiting list dilemma. Despite all efforts, deceased-donor donation cannot meet current needs and therefore, living donation demands serious consideration. This is supported by the fact that the risk to live donors is minimal, graft survival is significantly better than that of deceased-donor kidneys regardless of HLA matching, and professional ethical philosophers have fewer difficulties with voluntary living donations than with the removal of an organ from a cadaver. This is especially true in our region. Living-related donation has always been acceptable ethically. It is, however, limited by the number of willing and qualified donors, the high incidence of familial renal diseases, and donor coercion (especially in our area). Living-unrelated donation increases the availability of donors, decreases the chances of coercion, and eliminates the problem of consanguinity. It raises, however, the ethical issues of commercialism, transplant tourism, and organ trafficking. The arguments for and against living-unrelated donation are innumerable. They have been the subject of several international forums and have raised endless discussions. We have set long ago a series of rules and regulations that are in close agreement with the recent Amsterdam and Kuwait resolutions. We have been continually modifying them over the last 15 years to try to implement our ideal, which is to protect the interest of the living donor and avoid commercialism.

Given that in each country students represent the most progressive population group, as of 2001, the Blood Transfusion Institute of Serbia (BTIS) has been carrying the program of voluntary blood donation promotion and education of volunteers at the University of Belgrade (UB). In 2011, the BTIS intensified all activities at the UB. The aim of this study was to present activities performed from 2001 at the Blood Donors' Motivation Department (DMD) of the BTIS related with increasing the level of awareness on voluntary blood donation in the Belgrade students' population, enhancing their motivation to become voluntary blood donors (VBDs), increasing the number of blood donations at faculties of the UB, and increasing the number of blood donations in the UB students population compared with the total number of blood units collected by BTIS in Belgrade, with the emphasis on the year 2013. Initially, the applied methodology was based on encouraging students to donate blood through discussions and preparatory lectures, followed by organized blood drives. Appropriate selection of volunteers at each faculty was crucial. Besides their recognisable identity, they had to have remarkable communication skills and ability to positivly affect persons in their environment. The applied principle was based on retention of volunteers all through the final academic year, with the inclusion of new volunteers each year and 1,000 preparatory lectures on the annual basis. The activities were realized using two Facebook profiles, SMS messages and continuous notification of the public through the media. There was an increase in the average number of students in blood drives at the faculties from 2011, when the average number of the students per blood drive was 39, followed by 43 in 2012 and 46 in 2013. The number of students who donated blood in 2013 increased by 21.3% compared with 2012 data. The applied concept highly contributed to generation and retention of future VBDs willing to regularly donate blood in the coming years, with a minimum risk of transmission of transfusion transmissible diseases markers.

We sought to determine the frequency and significance of axillary lymph node visualization on bone scans performed with diphosphonates. Consecutive {sup 99m}Tc-methylene diphosphonate ({sup 99m}Tc-MDP) bone scans (2435) were inspected for axillary soft-tissue uptake. In positive cases, the results of physical examination, correlative imaging studies and serial bone scans were recorded, as was the site of venipuncture. Forty-eight studies (2%) showed axillary uptake ipsilateral to the injection site. Extravasation of tracer, documented by focal activity near the injection site, was present in every case. There was no association with axillary adenopathy, mass, induration of radiographically visible calcification. On some images,more » foci adjacent to the axilla were superimposed on the rib, scapula, or humerus. The bone-to-background ratio was frequently reduced; repeat imaging after 1-2 hr usually improved osseous detail. Ipsilateral axillary lymph node visualization due to extravasation of {sup 99m}Tc-MDP is frequently associated with additional foci superimposed on osseous structures simulating pathology. Delayed skeletal uptake is common in such cases and necessitates a greater time interval between injection and imaging. 7 refs., 3 figs.« less

The behavior of the luting cement and the cementation protocol are essential in the clinical success of ceramic restorations. The purpose of this study was to evaluate the bond stability of 2 resin cements and a yttria-stabilized tetragonal polycrystalline zirconia (Y-TZP) ceramic submitted to 2 surface treatments. Sixty plates of a Y-TZP ceramic were assigned to 3 groups according to the surface treatments: control, as sintered surface; methacryloxydecyl dihydrogen phosphate (MDP), coated with an MDP-based primer, and tribochemical silica-coating (TSC), coated with tribochemical silica. The plates of each group were further divided into 2 subgroups according to the resin cement as follows: RelyX adhesive resin cement (conventional) and RelyX Unicem (self-adhesive). Cylinders of resin cements (∅=0.75 mm × 0.5 mm in height) were built up on the ceramic surfaces, and the plates stored in distilled water at 37°C for either 24 hours or 6 months before being submitted to a microshear bond strength test. The data were submitted to 3-way ANOVA and the Tukey honestly significant difference test (α=.05). Three-way ANOVA showed statistical significance for the 3 independent factors: resin cement, surface treatment, and period of water immersion (P<.001). Unicem presented the highest microshear bond strength after 24 hours (MDP, 37.4 ±2.3 and TSC, 36.2 ±2.1 MPa). Except for RelyX adhesive resin cement applied on ceramic surfaces treated with TSC, the microshear bond strength of all the other groups decreased after 6 months of aging in water. The microshear bond strength decreased most in the control groups (-81.5% for ARC and -93.1% for Unicem). In the group treated with TSC, the microshear bond strength for Unicem decreased by 54.8% and in that treated with MDP-based primer by -42.5%. In the group treated with MDP-based primer, the microshear bond strength for RelyX ARC decreased by -52.8%. Irrespective of surface treatments, self-adhesive resin cement was not able to maintain the bond to Y-TZP ceramic after 6 months of aging in water.

This study approaches the decision to donate blood as a dynamic process involving interplay between blood donors' personal motives, donors' social contexts, and the donor recruitment and retention activities of blood collection agencies. Data were gathered from four blood donation clinics using in-depth interviews with Canadian Blood Services employees, donors, and nondonors in 25 organizations participating in Life Link, a donor recruitment program that supports organizations to educate employees about the benefits of blood donation. Further data were obtained from ethnographic observations of blood collection and donor recruitment activities. Thematic analysis resulted in three umbrella themes: leveraging social networks, embedding the clinic in the community, and donating blood and social reciprocity. Donor recruitment activities at all four clinics enhanced awareness of blood donation in the workplace by using experienced donors to motivate their coworkers in making a first-time donation. Clinic employees reported varying success in improving awareness of blood donation in the broader community, in part because of varying employee engagement in community-wide activities and celebrations. Altruistic motives were mentioned by experienced donors, who also identified a desire to reciprocate to their community as another strong motive. This study contextualizes donor recruitment and retention as involving activities that tie blood donation to meaningful aspects of donors' social networks and community. The findings point to the need for further analyses of the institutional dimensions of blood donation to develop effective strategies beyond appeals to altruism. © 2013 American Association of Blood Banks.

Family perception of organ donation has been explored by numerous authors using statements by the people who decided whether or not to donate the organs of a relative in a situation of brain death. Within this tradition, in this work, we analyze the discourse of six families who granted permission for organ donation and three who refused. We describe the process-based interpretation of this experience and identify psychosocial variables and processes that further our understanding of the decision finally adopted. We have identified two heuristics that guide family decision when organ donation is requested: the explicit or inferred will of the deceased and family attitudes to organ donation and transplant. It is postulated that the interaction of these two factors explains a large amount of the decisions made. We also hypothesize that a marked discrepancy between these two factors increases the importance of other aspects, especially the role of the transplant coordinator and of other healthcare personnel. These results support, at a social level, the implementation of transplant promotion programs; and at a healthcare level, the combined use of techniques of crisis intervention and attitude change.

We analyzed the opinion and understanding of medical students about organ donation and transplantation. 347 students voluntarily completed a questionnaire with 17 queries concerning organ donation and transplantation. They were analyzed to identify general tendencies and divided into five groups, according to their year of study (first through sixth year), to assess differences among the years. Students of the fifth and sixth years were placed in the same group. Results were analyzed by the Chi-square test. The intention to become a post mortem or living donor was of 89% and 90% respectively; however, only 62% were aware of living donation risks. 70% of the 347 students admitted regular or little knowledge of the subject, 90.2% considered organ transplantation an important issue for a medical graduation program, 76.9% considered informed/expressed consent the best organ donation criterion and 64.3% of them chose severity of patient disease as the best allocation condition. As students progressed in their studies their understanding about transplantation improved. Students of the fourth, fifth and sixth year manifested a negative attitude about organ donation to alcohol addicts, non donors, drug users, law offenders and foreigners. This data show the great interest and positive attitude of medical students toward organ donation and transplantation, despite the fact that most of them admitted having insufficient knowledge on the subject. A negative attitude by students of the fourth, fifth and sixth year on organ donation to alcohol addicts, non donors, drug users, law offenders and foreigners was also observed.
Decision Making in Kidney Paired Donation Programs with Altruistic Donors*
Li, Yijiang; Song, Peter X.-K.; Leichtman, Alan B.; Rees, Michael A.; Kalbfleisch, John D.
2014-01-01
In recent years, kidney paired donation (KPD) has been extended to include living non-directed or altruistic donors, in which an altruistic donor donates to the candidate of an incompatible donor-candidate pair with the understanding that the donor in that pair will further donate to the candidate of a second pair, and so on; such a process continues and thus forms an altruistic donor-initiated chain. In this paper, we propose a novel strategy to sequentially allocate the altruistic donor (or bridge donor) so as to maximize the expected utility; analogous to the way a computer plays chess, the idea is to evaluate different allocations for each altruistic donor (or bridge donor) by looking several moves ahead in a derived look-ahead search tree. Simulation studies are provided to illustrate and evaluate our proposed method. PMID:25309603

In previous work, we demonstrated the presence of hydroxyapetite (type II microcalcification), HAP, in triple negative MDA-MB-231 breast cancer cells. We used (18)F-NaF to detect these types of cancers in mouse models as the free fluorine, (18)F(-), binds to HAP similar to bone uptake. In this work, we investigate other bone targeting agents and techniques including (99m)Tc-MDP SPECT and Osteosense 750EX FMT imaging as alternatives for breast cancer diagnosis via targeting HAP within the tumor microenvironment. Thirteen mice were injected subcutaneously in the right flank with 10(6) MDA-MB-231 cells. When the tumor size reached ~0.6 cm(3), mice (n=9) were injected with ~37 MBq of (99m)Tc-MDP intravenously and then imaged one hour later in a NanoSPECT/CT or injected intravenously with 4 nmol/g of Osetosense 750EX and imaged 24 hours later in an FMT (n=4). The imaging probe concentration in the tumor was compared to that of muscle. Following SPECT imaging, the tumors were harvested, sectioned into 10 μm slices, and underwent autoradiography or von Kossa staining to correlate (99m)Tc-MDP binding with HAP distribution within the tumor. The SPECT images were normalized to the injected dose and regions-of-interest (ROIs) were drawn around bone, tumor, and muscle to obtain the radiotracer concentration in these regions in units of percent injected dose per unit volume. ROIs were drawn around bone and tumor in the FMT images as no FMT signal was observed in normal muscle. Uptake of (99m)Tc-MDP was observed in the bone and tumor with little or no uptake in the muscle with concentrations of 11.34±1.46 (mean±SD), 2.22±0.95, and 0.05±0.04%ID/cc, respectively. Uptake of Osteosense 750EX was also observed in the bone and tumor with concentrations of 0.35±0.07 (mean±SD) and 0.04±0.01picomoles, respectively. No FMT signal was observed in the normal muscle. There was no significant difference in the bone-to-tumor ratio between the two modalities (5.1±2.3 for SPECT and 8.8±2.2 for FMT) indicating that there is little difference in tumor uptake between these two agents. This study provides evidence of the accessibility of HAP within the breast tumor microenvironment as an in vivo imaging target for bone-seeking agents. SPECT imaging using (99m)Tc-MDP can be rapidly translated to the clinic. FMT imaging using Osteosense 750EX is not currently approved for clinical use and is limited to animal research.

The impact of disclosure on donor gamete participants: donors, intended parents and offspring.
Greenfeld, Dorothy A
2008-06-01
The present review examines recent publications that provide insight into how the trend toward nonanonymity and disclosure in gamete donation impacts donors, intended parents, and their donor-conceived children. Recent findings show an increase in donor programs that offer open-identity between donors and offspring. The psychological needs of gamete donors and their attitudes toward disclosure are increasingly given consideration. Qualitative research on how parents of donor gamete offspring make decisions about disclosure reveals that even when couples initially disagree about disclosing to offspring, most ultimately come to a united disclosure decision. The literature on the impact of disclosure on donor gamete offspring has extended to include children conceived through embryo donation and children born as a result of surrogacy. The absence of genetic or gestational link between parents and their child does not have a negative impact on parent-child relationships. Parents through surrogacy tend to disclose the method of family creation to their child, whereas parents through embryo donation tend to be secretive about their child's origins. The trend toward greater openness in gamete donation has been accompanied by an increase in programs offering open-identity donation. In addition, the psychological needs of gamete donors and their attitudes toward disclosure are increasingly being given consideration. Parents of donor gamete offspring give careful thought to their disclosure decisions, and the psychological well being of donor-conceived children does not seem to be impacted by those decisions.

Until a century ago, Korean medicine was based mainly on Oriental philosophies and ideas. From a religious perspective, Chinese Confucianism was prevalent in Korea at that time. Since Confucianists believe that it is against one's filial duty to harm his or her body, given to them by their parents, most Koreans did not donate their bodies or organs for education in the past. However, by the end of the 20th century, a unique fusion of Western and Oriental medicines were produced on the Korean Peninsula, revolutionizing traditional perspectives on the human body, mortality, and the relationship of medical science to society. Koreans began to think about others' lives as well as their own by realizing the importance of donating one's organs and bodies for scientific purposes. Since then, the number of people donating their bodies to Korean medical and dental schools for the purpose of improving academic learning has increased dramatically. In response, Korean medical schools have begun to hold various types of funeral ceremonies to honor body donors. We have compared such ceremonies performed in Korea with those performed in the United States of America and Taiwan. These ceremonies are viewed as a suitable way to pay proper respect to the dead and to promote knowledge about body donation programs in Korea. Overall, the transition of religions and social ethics in Korea has greatly facilitated body bequeathal programs, benefiting both medical education and the Korean public health administration.

Anatomy education in most African countries is limited by an insufficient number of cadavers for students to undertake dissection. This already significant shortage is exacerbated by an increasing number of medical schools and students. Virtual dissections are impractical in alleviating such a shortfall in African anatomy education, and further cadaver supply is challenged by unethical and dubious sources. This study was designed to assess the knowledge, attitudes, and practice of whole body and organ donation by Nigerian anatomists with the aim of finding solutions to the problems associated with the availability of cadavers in Nigerian medical schools. Out of 46 anatomists that participated in the survey, only 23.9% would consider donating their whole bodies and 60.9% their organs. More than 95% of respondents did not believe that body bequests could become the sole source of cadavers for anatomic dissection in Nigeria. Age and gender were not statistically significant in the choice of being a body or organ donor. The unacceptability to one's family members regarding body donation was the major reason for respondents' unwillingness to make a whole body donation. None of the 14 medical schools sampled in this study have yet instituted a body registration and donation program. The anatomists showed a high level of knowledge and awareness of body bequest programs, which were not reflected by their attitudes and practice. The authors recommend proactive measures aimed at improving the perception and attitudes of Nigerian anatomists. Copyright © 2012 American Association of Anatomists.

An innovative program recently initiated at the University of California, Los Angeles (UCLA) Medical Center allows people to donate a kidney in exchange for a voucher that a loved one can redeem for a kidney if and when needed. As a relatively new practice, the ethical implications of advanced kidney donation have not yet been widely discussed. This paper reflects on some of the bioethical issues at stake in this new donation program, as well as some broader philosophical issues related to the meaning and moral salience of commodification. I first consider whether the literature on commercial markets in organs--a longstanding topic of bioethical debate--can meaningfully inform ethical analysis of kidney voucher programs. Specifically, I consider whether and to what extent common objections to the exchange of kidneys for cash also apply to the exchange of kidneys for "kidney vouchers." Second, I argue that the contrast between the ethical issues raised by these two practices highlights the need to understand commodification as existing on a continuum, with different degrees of commodification giving rise to different ethical issues. Doing so can help sharpen our understanding of commodification as a moral concept, as well as its relevance to broader debates about the moral limits of markets. © The Author 2017.

Introduction For those with certain blood or bone cancers, bone marrow donation can mean the difference between life and death. The National Marrow Donor Program® (NMDP) operates the largest bone marrow registry of potential donors; however, at times when potential matches are identified, many donors opt not to donate. The purpose of this study was to describe perspectives from college-aged students on recruitment to a bone marrow donation registry and retention to the registry/follow-through with the donation process. Methods Researchers employed a one-time qualitative study using 7 focus groups comprised of 10 – 11 college students each (n = 76). Results Results yielded three overarching themes: donor recruitment, donor retention, and factors contributing to the overall donation process. More specifically, this study identified key factors affecting bone marrow donation in an essential population: facilitators, barriers, knowledge, and ‘goodness’. Additionally, marketing and communication were found to be major determinants of potential donors staying with the NMDP. Conclusion Better explanations and awareness/promotion campaigns are necessary for recruiting potential donors to the NMDP and to increase the likelihood that the donor will follow through with the donation should a potential match be identified. Recommendations from this study may improve recruitment and retention rates among the NMDP campaigns targeting college students. PMID:25632376

The supply of blood cell products requires from the National French Blood Institute (Établissement Français du Sang - EFS) to rely upon regular blood donors. Contact with donors, tailored to individuals as much as possible, helps them to donate on a regular basis. Within the context of a research program conducted with the Psychology Department of the Université de Caen Basse-Normandie, persuasive theoretical models from social psychology have been tested. These models allow adapting messages according to the motivation of donors. The content is centred on the previous donation, differently labelled according to two types of labelling: functional labelling and social labelling. Functional labelling points out the efficiency of what "has been done" (the previous blood donation), whereas social labelling emphasizes the social value of the individual. Different types of mailing invitations have been sent to 1917 donors from the Normandy database, invited to three different blood collections. Every experimental letter worked better than the standard EFS letter (which was used as the "control" letter) in terms of effective blood donation after reception of the letter. Some of the letters are more efficient in motivating donors than other ones. The letters labelling the previous blood donation as functional (efficiency of the donation) appeared more efficient than those with social label (social value) in whichever motivation induced.

Discussing deceased organ donation can be difficult not only for families but for health professionals who initiate and manage the conversations. It is well recognised that the methods of communication and communication skills of health professionals are key influences on decisions made by families regarding organ donation. This multicentre study is being performed in nine intensive care units with follow-up conducted by the Organ and Tissue Donation Service in New South Wales (NSW) Australia. The control condition is pre-intervention usual practice for at least six months before each site implements the intervention. The COMFORT intervention consists of six elements: family conversations regarding offers for organ donation to be led by a "designated requester"; family offers for donation are deferred to the designated requester; the offer of donation is separated from the end-of-life discussion that death is inevitable; it takes place within a structured family donation conversation using a "balanced" approach. Designated requesters may be intensivists, critical care nurses or social workers prepared by attending the three-day national "Family Donation Conversation" workshops, and the half-day NSW Simulation Program. The design is pre-post intervention to compare rates of family consent for organ donation six months before and under the intervention. Each ICU crosses from using the control to intervention condition after the site initiation visit. The primary endpoint is the consent rate for deceased organ donation calculated from 140 eligible next of kin families. Secondary endpoints are health professionals' adherence rates to core elements of the intervention; identification of predictors of family donation decision; and the proportion of families who regret their final donation decision at 90 days. The pragmatic design of this study may identify 'what works' in usual clinical settings when requesting organ donation in critical care areas, both in terms of changes in practice healthcare professionals are willing and able to adopt, and the effect this may have on desired outcomes. The findings of this study will be indicative of the potential benefits of the intervention and be relevant and transferrable to clinical settings in other states and countries.

[The costs of altruism in organ donation case analysis].
Netza Cardoso, Cruz; Casas Martínez, María Luz Lina; Ramírez García, Hugo
2010-01-01
Three main assumptions were considered for the structure of donation programs during the decade of the sixties: the first states that people, through altruism, would feel committed with the affected and therefore incentivized to donate. The second one states that the human body can not be valued in mercantile terms; therefore organ donation should not be done free of any charges. The last one states donation does not represent any type of harm or damage for the donor. Today, more tan four decades away from their instauration, these three assumptions have been violated and modified due to the way in which they were socialized through the donation protocols. Altruism did not seem to be as generalized as expected, and organ commerce has already gone beyond the legislative frameworks that intended to prevent it; one example is the case of India. In this paper we analyze--through two objectives--the repercussions and impact that took effect in four cases registered in the National Institute of Cardiology (Instituto Nacional de Cardiología) "Ignacio Chávez" in Mexico City. First objective: to describe the economical costs that the altruism-based donation protocol caused on the participant families. Second objective: to reflect on other costs that affected donators due to organ donation. It was found on the reviewed cases that repercussions can go beyond the economical issues; labor related, emotional and ethical repercussions were found too due to a undeniable sensation of reification that donors experience in view of the mechanization of the study protocol they undergo, specially when results are not the optimum. We circumscribe this paper’s analysis to living donors.

To reduce the number of family organ donation refusals, it is necessary not only to act on the general public but also on the health care system. In this respect, there are data suggesting that the percentage of hospital personnel against donation is high, especially among ancillary personnel. The objective herein was to analyze the attitudes of ancillary hospital professionals toward donation of their own organs and determine factors that conditioned such attitudes. A random sample in a third-level hospital with a solid organ transplant program was stratified by ancillary services: administrative, porters, maintenance, cleaning, and cooking. Attitudes toward donation of one's own organs after death were evaluated using a questionnaire on psychosocial aspects validated in our area. It included various psychosocial variables that could affect such attitudes. The Student t test and chi-square test were used to evaluate the data. We analyzed 277 respondents of mean age 43 +/- 8 years and 96% women. The level of acceptance of organ donation was 64% (n = 178), whereas 46% were either against or undecided (n = 98). The variables which determined the attitudes were understanding of brain death (P = .004); attitude toward cadaveric manipulation, especially toward autopsy (P = .013) and cremation (P = .004); concern about mutilation after donation (P = .014); religion (P = .032); partner's attitude toward donation (P < .0001); and possibility of needing an organ in the future (P = .031). Ancillary hospital personnel had similar attitudes toward donation as those of the general public as observed in other studies. The attitudes were determined by many psychosocial factors. A campaign to raise awareness among professionals has become a priority, given that working in a hospital, their unfavorable attitude could have a strong negative impact on the general public.

Between 2007 and 2012, Children Without Worms (CWW) oversaw the Johnson & Johnson (J&J) donation of Vermox (mebendazole) for treatment of school-age children to control soil-transmitted helminthiasis (STH). To identify factors associated with on-time, delayed, or missed mass drug administration (MDA) interventions, and explore possible indicators for supply chain performance for drug donation programs, we reviewed program data for the 14 STH-endemic countries CWW supported during 2007-2012. Data from drug applications, shipping records, and annual treatment reports were tracked using Microsoft Excel. Qualitative data from interviews with key personnel were used to provide additional context on the causes of delayed or missed MDAs. Four possible contributory factors to delayed or missed MDAs were considered: production, shipping, customs clearance, and miscellaneous in-country issues. Coverage rates were calculated by dividing the number of treatments administered by the number of children targeted during the MDA. Of the approved requests for 78 MDAs, 54 MDAs (69%) were successfully implemented during or before the scheduled month. Ten MDAs (13%) were classified as delayed; seven of these were delayed by one month or less. An additional 14 MDAs (18%) were classified as missed. For the 64 on-time or delayed MDAs, the mean coverage was approximately 88%. To continue to assess the supply chain processes and identify areas for improvement, we identified four indicators or metrics for supply chain performance that can be applied across all neglected tropical disease (NTD) drug donation programs: (1) donor having available inventory to satisfy the country request for donation; (2) donor shipping the approved number of doses; (3) shipment arriving at the Central Medical Stores one month in advance of the scheduled MDA date; and (4) country programs implementing the MDA as scheduled.

The Spanish model is the model adopted by many countries to increase their donation rate, being the implication of the healthcare professionals one of the keys to this success. The attitude of these before the donation is crucial for the hour of influence on the population. Organ transplantation has been established as an effective treatment that has been improving over the years. The objective was to determine the knowledge and attitudes of health professionals before the donation of organs. Cross-sectional descriptive study. An ad hoc questionnaire was conducted and distributed among the health professionals (medical staff, nurses and nursing assistants) of a tertiary hospital during February 2015. A total of 615 potential participants were estimated in the different areas of the hospital. A total of 342 completed questionnaires were collected (55%). The statistical analysis with SPSS® Statistics for Windows. Version 20.0. A level of significance P lower than 0.05 was used in all the analyses. The average age of the respondents was 43.34 (SD = 10.37) years, being 86.6% women and 60% nurses. 35.5% showed good knowledge about the donation process, being higher in men (51.1% Vs 33.1%, p lower than 0.05), medical personnel (55% vs 34.3% vs 31.9%). %; p lower than 0.05) and lower in those services with a direct relationship with the donation process (36.8% vs 31.9%, p lower than 0.05). 71% of the professionals expressed their willingness to donate their organs, with special sensitivity towards donation those services in direct relation with the donation program (82.2% vs 65.9%, OR: 1.24, p lower than 0.001 ). 50% of the professionals would donate the organs of a family member; the medical group had the highest percentage (70% vs 50.7% vs 40.4%, OR: 3.8, p lower than 0.05). 74.5% knew some Spanish legal document about donation and transplants. Health professionals as a whole have a low level of knowledge; but a good attitude towards donation.

Public awareness of organ donation fundamentally affects the organ transplantation programs. This study was performed to assess the attitude and willingness of high school adolescents regarding organ donation. The study population consisted of 416 high school girls who were studying in four grades of three educational courses. Data were collected by a questionnaire and included demographic variables and attitude and willingness, which were assessed based on the Likert scale. The SPSS v.16 was used for data analysis. The mean age of the study subjects was 16.26 ± 1.06 years, 31% studied in grade-1, 27% in grade-2 (25% natural sciences, 27% mathematics and 48% humanities), 26% in grade-3 (30% natural sciences, 34% mathematics and 36% humanities) and 16% in pre-university stage (32% natural sciences, 42% mathematics and 26% humanities). The students had a highly positive attitude toward organ donation (mean score 4.2 ± 0.54). The greatest willingness for organ donation was concerning the kidney (88%) and heart (84%), followed by the liver (83.4%), pancreas (79.6%), cornea (67.8%) and skin (51%). Willingness for deceased as well as living organ donation was indicated by 92% and 47%, respectively, of the participants. Organ donation was considered acceptable only to relatives by 5% of the participants when the donors were deceased donors and by 16% of the participants when the donors were living donors; donation to all needy persons from deceased donors was accepted by 87% of the participants and from living donors by 31%. The purpose of donation was stated as lending help to others by 89% and progression of science by 40.2% of the participants. Willingness for organ donation from a deceased relative was declared by 63% of the students. There was significant positive correlation between willingness for organ donation and attitude (P <0.001). In addition, attitude and willingness had positive correlation with educational levels, age and educational courses. Our study suggests that Iranian adolescents have a great attitude and willingness toward organ donation, which reflects favorable knowledge of transplantation. Further research on public awareness in both genders and various age ranges is needed.

A prospective, comparative study was made of the efficacy of technetium-99m pyrophosphate (Tc PYP) and technetium-99m methylene diphosphonate (Tc MDP) in detecting soft-tissue amyloidois. Tc PYP and Tc MDP scans were obtained within ten-day intervals in seven patients with histologically proven amyloidosis. Tc PYP was a better scanning agent for soft-tissue amyloidosis in all patients. Cardiac and hepatic involvement were proved by autopsy in one patient. Involvement of the heart was confirmed by echocardiography in five patients. The potential use of tc PYP scannning as a screening test for soft-tissue amyloidosis is discussed.

Health workers' awareness and knowledge of transplant medicine can improve people's sensitivity and reduce their degree of opposition to donations. The medical literature contains numerous examples of education programs aimed at university students. This work describes the experience of an education program for students of the second and third year of a nursing degree course. From April to September 2013, an education program was set up for 80 university students. It was divided into 3 stages: group self-learning based on prearranged topics, sharing of the results, and participation in the final seminar. The effectiveness was assessed according to a pretest/posttest design. The first questionnaire contained 19 questions, and the second contained 27. The questions were subdivided into specific areas: subjective knowledge, objective knowledge, attitude, awareness, participation in the event, evaluation of the information material handed out, and appreciation of the tools used. There was a significant increase for items relating to knowledge, whereas awareness and attitude (already high at the start of the program) showed no changes. After the program, many students discussed the question of donation with their relatives and friends, and about 70% filled in a donor card. The students expressed a highly positive opinion of the initiative and the tools used. The initiative proved its validity, improving subjective and objective knowledge to a statistically significant extent and also increasing awareness and attitude. The students' evaluation was extremely positive. Copyright © 2015 Elsevier Inc. All rights reserved.
Exploring Motivations, Awareness of Side Effects, and Attitudes among Potential Egg Donors

This research study surveyed prospective egg donors at orientation to (a) understand women’s motivations to donate eggs, (b) assess awareness and knowledge of egg donation prior to entry into the egg donation program, and (c) explore attitudes toward egg donation. Ninety-two women completed the questionnaire at one fertility clinic located in the Midwest between August 2011 and August 2012. Descriptive and inferential statistics as well as textual analysis were used to analyze the data. Three themes emerged regarding participant motivations: (1) altruistic, (2) financial, and (3) desire to pass on genetic material. The majority of participants were unconcerned with potential physical and psychological side effects; however, differences emerged based on motherhood status and educational level. Although potential donors felt recipients should receive some information about the donor, they tended to value privacy regarding information giving to resultant offspring. This research study has implications for social work practice, policy, and future research. It is crucial that women receive adequate procedural and side effect information prior to engaging in egg donation. PMID:27263197
Does Confucianism allow for body donation?
Jones, D Gareth; Nie, Jing-Bao
2018-01-16
Confucianism has been widely perceived as a major moral and cultural obstacle to the donation of bodies for anatomical purposes. The rationale for this is the Confucian stress on xiao (filial piety), whereby individuals' bodies are to be intact at death. In the view of many, the result is a prohibition on the donation of bodies to anatomy departments for the purpose of dissection. The role of dissection throughout the development of anatomy within a Confucian context is traced, and in contemporary China the establishment of donation programs and the appearance of memorial monuments is noted. In reassessing Confucian attitudes, the stress laid on a particular interpretation of filial piety is questioned, and an attempt is made to balance this with the Confucian emphasis on a moral duty to those outside one's immediate family. The authors argue that the fundamental Confucian norm ren (humaneness or benevolence) allows for body donation as people have a moral duty to help others. Moreover, the other central Confucian value, li (rites), offers important insights on how body donation should be performed as a communal activity, particularly the necessity of developing ethically and culturally appropriate rituals for body donation. In seeking to learn from this from a Western perspective, it is contended that in all societies the voluntary donation of bodies is a deeply human activity that is to reflect the characteristics of the community within which it takes place. This is in large part because it has educational and personal repercussions for students. Anat Sci Educ. © 2018 American Association of Anatomists. © 2018 American Association of Anatomists.

A rapid thiolytic degradation and cleanup procedure was developed for analyzing tannins directly in chlorophyll-containing sainfoin ( Onobrychis viciifolia ) plants. The technique proved suitable for complex tannin mixtures containing catechin, epicatechin, gallocatechin, and epigallocatechin flavan-3-ol units. The reaction time was standardized at 60 min to minimize the loss of structural information as a result of epimerization and degradation of terminal flavan-3-ol units. The results were evaluated by separate analysis of extractable and unextractable tannins, which accounted for 63.6-113.7% of the in situ plant tannins. It is of note that 70% aqueous acetone extracted tannins with a lower mean degree of polymerization (mDP) than was found for tannins analyzed in situ. Extractable tannins had between 4 and 29 lower mDP values. The method was validated by comparing results from individual and mixed sample sets. The tannin composition of different sainfoin accessions covered a range of mDP values from 16 to 83, procyanidin/prodelphinidin (PC/PD) ratios from 19.2/80.8 to 45.6/54.4, and cis/trans ratios from 74.1/25.9 to 88.0/12.0. This is the first high-throughput screening method that is suitable for analyzing condensed tannin contents and structural composition directly in green plant tissue.

A role for the nucleotide-binding oligomerization domain 2 (NOD2) receptor in pulmonary innate immune responses has recently been explored. In the present study, we investigated the role that NOD2 plays in human alveolar macrophage innate responses and determined its involvement in the response to infection with virulent Mycobacterium tuberculosis. Our results showed that NOD2 was expressed in human alveolar macrophages, and significant amounts of IL-1β, IL-6, and TNF-α were produced upon ligand recognition with muramyldipeptide (MDP). NOD2 ligation induced the transcription and protein expression of the antimicrobial peptide LL37 and the autophagy enzyme IRGM in alveolar macrophages, demonstrating a novel function for this receptor in these cells. MDP treatment of alveolar macrophages improved the intracellular growth control of virulent M. tuberculosis; this was associated with a significant release of TNF-α and IL-6 and overexpression of bactericidal LL37. In addition, the autophagy proteins IRGM, LC3 and ATG16L1 were recruited to the bacteria-containing autophagosome after treatment with MDP. In conclusion, our results suggest that NOD2 can modulate the innate immune response of alveolar macrophages and play a role in the initial control of respiratory M. tuberculosis infections. © 2012 WILEY-VCH Verlag GmbH & Co.

Brain-tumor segmentation is an important clinical requirement for brain-tumor diagnosis and radiotherapy planning. It is well-known that the number of clusters is one of the most important parameters for automatic segmentation. However, it is difficult to define owing to the high diversity in appearance of tumor tissue among different patients and the ambiguous boundaries of lesions. In this study, a nonparametric mixture of Dirichlet process (MDP) model is applied to segment the tumor images, and the MDP segmentation can be performed without the initialization of the number of clusters. Because the classical MDP segmentation cannot be applied for real-time diagnosis, a new nonparametric segmentation algorithm combined with anisotropic diffusion and a Markov random field (MRF) smooth constraint is proposed in this study. Besides the segmentation of single modal brain-tumor images, we developed the algorithm to segment multimodal brain-tumor images by the magnetic resonance (MR) multimodal features and obtain the active tumor and edema in the same time. The proposed algorithm is evaluated using 32 multimodal MR glioma image sequences, and the segmentation results are compared with other approaches. The accuracy and computation time of our algorithm demonstrates very impressive performance and has a great potential for practical real-time clinical use.

Membrane microdomains are implicated in the trafficking and sorting of several membrane proteins. In particular GPI-anchored proteins cluster into Triton X-100 resistant, cholesterol- and sphingolipid-rich membrane microdomains and are sorted to the apical membrane. A growing body of evidence has pointed to the existence of other types of microdomains that are insoluble in detergents, such as Lubrol WX and Tween-20. Here, we report on the role of detergent-resistant membranes formed at early stages in the biosynthesis of membrane dipeptidase (MDP), a GPI-anchored protein, on its trafficking and sorting. Pulse-chase experiments revealed a retarded maturation rate of the GPI-anchor deficient mutant (MDPDeltaGPI) as compared to the wild type protein (wtMDP). However, Golgi to cell surface delivery rate did not show a significant difference between the two variants. On the other hand, early biosynthetic forms of wtMDP were partially insoluble in Tween-20, while MDPDeltaGPI was completely soluble. The lack of association of MDPDeltaGPI with detergent-resistant membranes prior to maturation in the Golgi and the reduction in its trafficking rate strongly suggest the existence of an early trafficking control mechanisms for membrane proteins operating at a level between the endoplasmic reticulum and the cis-Golgi.

Tannins from the leaves of a medicinal mangrove plant, Ceriops tagal, were purified and fractionated on Sephadex LH-20 columns. 13C nuclear magnetic resonance (13C-NMR), reversed/normal high performance liquid chromatography electrospray ionization mass spectrometry (HPLC-ESI MS) and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDT-TOF MS) analysis showed that the tannins were predominantly B-type procyanidins with minor A-type linkages, galloyl and glucosyl substitutions, and a degree of polymerization (DP) up to 33. Thirteen subfractions of the procyanidins were successfully obtained by a modified fractionation method, and their antioxidant activities were investigated using 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging capacity and ferric reducing antioxidant power (FRAP) method. All these subfractions exhibited potent antioxidant activities, and eleven of them showed significantly different mean DP (mDP) ranging from 1.43±0.04 to 31.77±1.15. Regression analysis demonstrated that antioxidant activities were positively correlative with mDP when around mDP <10, while dropped and then remained at a level similar to mDP = 5 with around 95 µg ml−1 for DPPH scavenging activity and 4 mmol AAE g−1 for FRAP value.

The use of unclaimed bodies for anatomical dissection has been the main method of instruction at our institution. There is however a shortage of cadavers for dissection given the increase in the number of medical schools as well as in the number of students enrolling in these schools. This shortage could be mitigated by having voluntary human body donation programs. This study aimed at assessing the attitudes of medical students and surgical residents towards body donation for anatomy learning. We conducted an online survey involving 72 first-year medical students and 41 surgical residents at University of Nairobi who had completed one year of anatomy dissection. For the medical students, this was their first dissection experience while it was the second exposure for the surgery trainees. Most of the surgical trainees (70.7%) and medical students (68.1%) were opposed to self-body donation. This was mainly due to cultural (37%) and religious (20%) barriers. Surprisingly, of those not willing to donate themselves, 67.9% (82.8% surgical trainees, 59.2% medical students) would recommend the practice to other people. Exposure to repeated dissection does not change the perceptions towards body donation. It is noteworthy that culture and religion rank high as clear barriers amongst this “highly informed” group of potential donors. PMID:27190650

This study aimed at assessing the attitudes of medical students and surgical residents towards body donation for anatomy learning. We conducted an online survey involving 72 first-year medical students and 41 surgical residents at University of Nairobi who had completed one year of anatomy dissection. For the medical students, this was their first dissection experience while it was the second exposure for the surgery trainees. Most of the surgical trainees (70.7%) and medical students (68.1%) were opposed to self-body donation. This was mainly due to cultural (37%) and religious (20%) barriers. Surprisingly, of those not willing to donate themselves, 67.9% (82.8% surgical trainees, 59.2% medical students) would recommend the practice to other people. Exposure to repeated dissection does not change the perceptions towards body donation. It is noteworthy that culture and religion rank high as clear barriers amongst this "highly informed" group of potential donors.

The desorption of CO from zeolites CuY and CuX was followed by TPD-IR method. This is a combination of temperature programmed desorption and IR spectroscopy. In this method, the status of activated zeolite (before adsorption), the process of adsorption, and the status of adsorbed molecules can be followed by IR spectroscopy, and the process of desorption (with linear temperature increase) can be followed both by IR spectroscopy and by mass spectrometry. IR spectra have shown two kinds of Cu + sites in both CuY and CuX. Low frequency (l.f.) band (2140 cm -1 in CuY and 2130 cm -1 in CuX) of adsorbed CO represents Cu + sites for which π back donation is stronger and σ donation is weaker whereas high frequency h.f. band (2160 cm -1 in CuY and 2155 cm -1 in CuX) represent Cu + sites for which π back donation is weaker and σ donation is stronger. The TPD-IR experiments evidenced that the Cu + sites represented by l.f. band bond CO more weakly than those represented by h.f. one, indicating that σ donation has more important impact to the strength of Cu +-CO bonding. On the contrary, π back donation has bigger contribution to the activation of adsorbed molecules.

The Brain and Body Donation Program (BBDP) at Banner Sun Health Research Institute (http://www.brainandbodydonationprogram.org) started in 1987 with brain-only donations and currently has banked more than 1600 brains. More than 430 whole-body donations have been received since this service was commenced in 2005. The collective academic output of the BBDP is now described as the Arizona Study of Aging and Neurodegenerative Disorders (AZSAND). Most BBDP subjects are enrolled as cognitively normal volunteers residing in the retirement communities of metropolitan Phoenix, Arizona. Specific recruitment efforts are also directed at subjects with Alzheimer’s disease, Parkinson’s disease and cancer. The median age at death is 82. Subjects receive standardized general medical, neurological, neuropsychological and movement disorders assessments during life and more than 90% receive full pathological examinations by medically licensed pathologists after death. The Program has been funded through a combination of internal, federal and state of Arizona grants as well as user fees and pharmaceutical industry collaborations. Subsets of the Program are utilized by the US National Institute on Aging Arizona Alzheimer’s Disease Core Center and the US National Institute of Neurological Disorders and Stroke National Brain and Tissue Resource for Parkinson’s Disease and Related Disorders. Substantial funding has also been received from the Michael J. Fox Foundation for Parkinson’s Research. The Program has made rapid autopsy a priority, with a 3.0-hour median postmortem interval for the entire collection. The median RNA Integrity Number (RIN) for frozen brain and body tissue is 8.9 and 7.4, respectively. More than 2500 tissue requests have been served and currently about 200 are served annually. These requests have been made by more than 400 investigators located in 32 US states and 15 countries. Tissue from the BBDP has contributed to more than 350 publications and more than 200 grant-funded projects. PMID:25619230

Femoral head donation at the time of hip replacement surgery provides a much needed resource of bone allograft to orthopaedic surgeons. Prior to 2005, potential femoral head donors were identified and consented in the hospital setting on the day of surgery. This resulted in over 40 % of donations failing post operatively suggesting that more effort could be given to pre-operative screening resulting in substantial savings in the cost associated with collection and testing of donors who were subsequently failed. The Donor Liaison role was implemented in 2005 to coordinate a Femoral Head Donation program maximising the number of successful donations through pre-operative screening. This study reviews the effectiveness of pre-operative screening of potential femoral head donors at PlusLife from 2002-2012. A retrospective audit of the database was undertaken 2002-2012 and medical/social reasons for pre-operative and postoperative failures were collated into 4 main categories to enable comparison: malignancy, autoimmune conditions, variant Creutzfeldt Jakob disease risk and general medical/social reasons. The number of femoral heads failed post operatively has decreased significantly from 26 % in 2003 to 6 % in 2012. A cost of $121,000 was expended on femoral heads failed post operatively in 2004, as compared to $20,350 in 2012. Donors excluded due to the 4 main categories (medical/social history) were identified pre-operatively in over 80 % of all cases. Preoperative screening of femoral head donors through a coordinated Femoral Head Donation Program is a safe and cost effective method.
Chemical interaction of glycero-phosphate dimethacrylate (GPDM) with hydroxyapatite and dentin.

Although the functional monomer glycero-phosphate dimethacrylate (GPDM) has since long been used in several dental adhesives and more recently in self-adhesive composite cements and restoratives, its mechanism of chemical adhesion to hydroxyapatite (HAp) is still unknown. We therefore investigated the chemical interaction of GPDM with HAp using diverse chemical analyzers and ultra-structurally characterized the interface of a GPDM-based primer formulation with dentin. HAp particles were added to a GPDM solution for various periods, upon which they were thoroughly washed with ethanol and water prior to being air-dried. As control, 10-methacryloyloxydecyl dihydrogen phosphate (MDP) was used. The molecular interaction of GPDM with HAp was analyzed using X-ray diffraction (XRD) and solid-state nuclear magnetic resonance (NMR) spectroscopy. Crystal formation upon application of GPDM onto dentin was analyzed using thin-film XRD (TF-XRD). Its hydrophobicity was measured using contact-angle measurement. The interaction of GPDM with dentin was characterized using transmission electron microscopy (TEM). XRD revealed the deposition of dicalcium phosphate dihydrate (DCPD: CaHPO 4 ·2H 2 O) on HAp after 24h. NMR confirmed the adsorption of GPDM onto HAp. However, GPDM was easily removed after washing with water, unlike MDP that remained adhered to HAp. Dentin treated with GPDM appeared more hydrophilic compared to dentin treated with MDP. TEM disclosed exposed collagen in the hybrid layer produced by the GPDM-based primer formulation. Although GPDM adsorbed to HAp, it did not form a stable calcium salt. The bond between GPDM and HAp was weak, unlike the strong bond formed by MDP to HAp. Due to its high hydrophilicity, GPDM might be an adequate monomer for an etch-and-rinse adhesive, but appears less appropriate for a 'mild' self-etch adhesive that besides micro-retention ionically interacts with HAp, or for a self-adhesive restorative material.

To determine the effects of exercise on the distribution and pharmacokinetics of technetium Tc 99m medronate ((99m)Tc-MDP) following intra-articular (IA) injection in horses. 5 horses. 1 antebrachiocarpal joint (ACJ)/horse was assigned to the exercised group (n = 5), and the contralateral ACJ was evaluated in the nonexercised group (5) after a minimum washout period of 7 days. Following IA injection of (99m)Tc-MDP (148 MBq), blood and scintigraphic images of the carpus were obtained at 5, 10, 15, 20, 25, 30, 45, 60, 90, 120, 240, 360, 480, 600, 720, and 1,440 minutes. Plasma and scintigraphic radioactivity were determined over time, and pharmacokinetic parameters were generated via noncompartmental and compartmental analyses. Each horse was monitored via physical and lameness examination and ACJ synovial fluid analysis before injection and at days 1, 2, 3, and 7. Lameness was not observed. Mean ± SD synovial fluid WBC count increased at day 1 (exercised, 721 ± 234 cells/μL; nonexercised, 948 ± 223 cells/μL), but returned to baseline at days 3 and 7 Mean time to maximum plasma radioactivity was earlier in the exercised group (16.00 ± 2.35 minutes) than the nonexercised group (43.75 ± 3.64 minutes). Linear regression of the scintigraphic radioactivity-time curves revealed a greater negative slope in the exercised group within the first 25 minutes. There was no difference in absorption or elimination rate constants in a 2-compartment model. IA injection of (99m)Tc-MDP was safe and effective for evaluating synovial solute distribution. Exercise significantly increased early transfer of (99m)Tc-MDP from the ACJ into plasma, although absorption and elimination rate constants were not affected. Exercise may affect synovial clearance and withdrawal times of medications administered IA.

Background This costing study in Malawi is a first evaluation of a Maternal Influenza Immunization Program Costing Tool (Costing Tool) for maternal immunization. The tool was designed to help low- and middle-income countries plan for maternal influenza immunization programs that differ from infant vaccination programs because of differences in the target population and potential differences in delivery strategy or venue. Methods This analysis examines the incremental costs of a prospective seasonal maternal influenza immunization program that is added to a successful routine childhood immunization and antenatal care program. The Costing Tool estimates financial and economic costs for different vaccine delivery scenarios for each of the major components of the expanded immunization program. Results In our base scenario, which specifies a donated single dose pre-filled vaccine formulation, the total financial cost of a program that would reach 2.3 million women is approximately $1.2 million over five years. The economic cost of the program, including the donated vaccine, is $10.4 million over the same period. The financial and economic costs per immunized pregnancy are $0.52 and $4.58, respectively. Other scenarios examine lower vaccine uptake, reaching 1.2 million women, and a vaccine purchased at $2.80 per dose with an alternative presentation. Conclusion This study estimates the financial and economic costs associated with a prospective maternal influenza immunization program in a low-income country. In some scenarios, the incremental delivery cost of a maternal influenza immunization program may be as low as some estimates of childhood vaccination programs, assuming the routine childhood immunization and antenatal care systems are capable of serving as the platform for an additional vaccination program. However, purchasing influenza vaccines at the prices assumed in this analysis, instead of having them donated, is likely to be challenging for lower-income countries. This result should be considered as a starting point to understanding the costs of maternal immunization programs in low- and middle-income countries. PMID:29281710

Constant monitoring is paramount in order to detect the criticalities and improve the results of the deceased donation process. Concomitant with the institution of a regional transplantation service authority--Organizzazione Toscana Trapianti--in 2003, Tuscany adopted a program of quality assurance of the deceased donation process by compulsory reporting of all encephalic deaths from local intensive care units to the regional transplant office in Florence. The indicators we adopted were the efficiency of deceased donor (DD) identification, expressed as the ratio of encephalic deaths (ED) to total deaths with encephalic lesions (EL) (ie, ED/EL); the efficiency of DD reporting, expressed as the ratio of reported potential DD (RPDD) to total ED (ie, RPDD/ED); the efficacy of the DD process, as the ratio between actual DD (ADD) to total ED (ie, ADD/ED); the conversion rate; the percent of opposition to donation; and the incidence of DD maintenance failures. Data were collected prospectively, stratified by regional hospital consortia (Aziende Sanitarie Locali) and compared with international benchmarks. In the period 2003-2006 the mean efficiency of DD identification was 48.3%+/-4.4% (range 42.6%-53.2%); the mean efficiency of DD reporting was 95.2%+/-2.5% (range 92.5%-98.5%); the mean efficacy of the deceased donation process was 51.8%+/-2.4% (range 48.6%-54.4%); the mean conversion rate was 59.6%+/-2.2% (range 57.6%-62.7%); the mean opposition rate was 31.9%+/-1.1% (range 30.6%-33.2%); and the incidence of DD maintenance failure was 5%+/-2.9% (range 2.2%-8.7%). The breakdown analysis revealed wide interhospital variability in terms of efficiency of DD identification (from a low of 25% to a high of 80%); efficacy of the donation process (from a low of 22% to a high of 79%); and conversion rate (from a low of 29% to a high of 79%). Our results highlight that the donation process gets started in about 50% of eligible cases. Further strategies are favored to address this critical area.

Pigment-grade titanium dioxide (TiO 2 ) particles are an additive to some foods (E171 on ingredients lists), toothpastes, and pharma-/nutraceuticals and are absorbed, to some extent, in the human intestinal tract. TiO 2 can act as a modest adjuvant in the secretion of the pro-inflammatory cytokine interleukin 1β (IL-1β) when triggered by common intestinal bacterial fragments, such as lipopolysaccharide (LPS) and/or peptidoglycan. Given the variance in human genotypes, which includes variance in genes related to IL-1β secretion, we investigated whether TiO 2 particles might, in fact, be more potent pro-inflammatory adjuvants in cells that are genetically susceptible to IL-1β-related inflammation. We studied bone marrow-derived macrophages from mice with a mutation in the nucleotide-binding oligomerisation domain-containing 2 gene (Nod2 m/m ), which exhibit heightened secretion of IL-1β in response to the peptidoglycan fragment muramyl dipeptide (MDP). To ensure relevance to human exposure, TiO 2 was food-grade anatase (119 ± 45 nm mean diameter ± standard deviation). We used a short 'pulse and chase' format: pulsing with LPS and chasing with TiO 2 +/- MDP or peptidoglycan. IL-1β secretion was not stimulated in LPS-pulsed bone marrow-derived macrophages, or by chasing with MDP, and only very modestly so by chasing with peptidoglycan. In all cases, however, IL-1β secretion was augmented by chasing with TiO 2 in a dose-dependent fashion (5-100 μg/mL). When co-administered with MDP or peptidoglycan, IL-1β secretion was further enhanced for the Nod2 m/m genotype. Tumour necrosis factor α was triggered by LPS priming, and more so for the Nod2 m/m genotype. This was enhanced by chasing with TiO 2 , MDP, or peptidoglycan, but there was no additive effect between the bacterial fragments and TiO 2 . Here, the doses of TiO 2 that augmented bacterial fragment-induced IL-1β secretion were relatively high. In vivo, however, selected intestinal cells appear to be loaded with TiO 2 , so such high concentrations may be 'exposure-relevant' for localised regions of the intestine where both TiO 2 and bacterial fragment uptake occurs. Moreover, this effect is enhanced in cells from Nod2 m/m mice indicating that genotype can dictate inflammatory signalling in response to (nano)particle exposure. In vivo studies are now merited.
Scientific, legal, and ethical challenges of end-of-life organ procurement in emergency medicine.
Rady, Mohamed Y; Verheijde, Joseph L; McGregor, Joan L
2010-09-01
We review (1) scientific evidence questioning the validity of declaring death and procuring organs in heart-beating (i.e., neurological standard of death) and non-heart-beating (i.e., circulatory-respiratory standard of death) donation; (2) consequences of collaborative programs realigning hospital policies to maximize access of procurement coordinators to critically and terminally ill patients as potential donors on arrival in emergency departments; and (3) ethical and legal ramifications of current practices of organ procurement on patients and their families. Relevant publications in peer-reviewed journals and government websites. Scientific evidence undermines the biological criteria of death that underpin the definition of death in heart-beating (i.e., neurological standard) and non-heart-beating (i.e., circulatory-respiratory standard) donation. Philosophical reinterpretation of the neurological and circulatory-respiratory standards in the death statute, to avoid the appearance of organ procurement as an active life-ending intervention, lacks public and medical consensus. Collaborative programs bundle procurement coordinators together with hospital staff for a team-huddle and implement a quality improvement tool for a Rapid Assessment of Hospital Procurement Barriers in Donation. Procurement coordinators have access to critically ill patients during the course of medical treatment with no donation consent and with family or surrogates unaware of their roles. How these programs affect the medical care of these patients has not been studied. Policies enforcing end-of-life organ procurement can have unintended consequences: (1) erosion of care in the patient's best interests, (2) lack of transparency, and (3) ethical and legal ramifications of flawed standards of declaring death.

[Oocyte donation in France and national balance sheet (GEDO). Different European approaches].
Letur-Könirsch, H
2004-02-01
Oocyte donation (OD), a technique successfully used in Assisted reproductive techniques (ART), has been effective for 20 years as the palliative treatment of certain exocrine ovarian failures. Its indications have also been extended to cover some genetic diseases and documented occult ovarian insufficiency. In France, after an extensive judicial and ethical deliberation, OD was deemed legal and its practice was proscribed in the Bioethics Laws 94-653 and 94-654 of 29 July 1994. Its essential underlying principles are: voluntary, free, anonymous and confidential OD; according to a French decree to meet safety concerns, OD-derived embryos must be quarantined for six months. In vitro fertilization (IVF) programs using donated oocytes are conducted in authorized centers under the responsibility of physicians authorized to retrieve and manipulate donated oocytes. The managers of these programs are the system's keystone, as their role includes, among other, the verification of indications, legal documents, public health safety, anonymous pairing of donor and recipient, and the collection of outcome data. At present, depending of the year, French programs have achieved 17-22% clinical pregnancy rates from transferred OD-derived frozen-thawed embryos, and follow-up studies reported excellent results concerning family relationships, and the physical and psychological development of the children. However, difficulties encountered in the daily practice of OD have led concerned physicians to form the Study group for OD (GEDO) to explore different topics with the aim of improving the overall management of this form of ART. We discussed these points herein, in comparison with the approaches of other European countries.
Bodies for Anatomy Education in Medical Schools: An Overview of the Sources of Cadavers Worldwide.
Habicht, Juri L; Kiessling, Claudia; Winkelmann, Andreas
2018-03-20
The International Federation of Associations of Anatomists (IFAA) recommended in 2012 that only donated bodies be used for anatomy teaching and research. However, in many countries around the world, anatomists still depend on bodies that do not stem from voluntary donations by the deceased, but rather are "unclaimed." A broad search of the literature was conducted to produce a baseline overview of the sources of cadavers used for anatomy teaching in undergraduate medical curricula on a global scale. Information from the literature search was supplemented with data from a 2016-2017 survey of selected senior local anatomists. Of 165 countries with medical schools, information was gathered for 71. In 22 (32%) of the 68 countries that use cadavers for anatomy teaching, body donation is the exclusive source of bodies. However, in most other countries, unclaimed bodies remain the main (n = 18, 26%) or exclusive (n = 21, 31%) source. Some countries import cadavers from abroad, mainly from the United States or India. In one country, bodies of executed persons are given to anatomy departments. The heterogeneous geographical distribution of body sources cannot easily be accounted for, but religion, culture, and folk beliefs about what should happen to bodies after death seem to play a role. Implementation of the IFAA recommendations still has a long way to go, but it is encouraging that functioning body donation programs exist on all continents and that there are examples of recent rises in donations and of anatomists initiating new donation programs.This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

The Control Point Library Building System. [for Landsat MSS and RBV geometric image correction
NASA Technical Reports Server (NTRS)
Niblack, W.
1981-01-01
The Earth Resources Observation System (EROS) Data Center in Sioux Falls, South Dakota distributes precision corrected Landsat MSS and RBV data. These data are derived from master data tapes produced by the Master Data Processor (MDP), NASA's system for computing and applying corrections to the data. Included in the MDP is the Control Point Library Building System (CPLBS), an interactive, menu-driven system which permits a user to build and maintain libraries of control points. The control points are required to achieve the high geometric accuracy desired in the output MSS and RBV data. This paper describes the processing performed by CPLBS, the accuracy of the system, and the host computer and special image viewing equipment employed.

Mirels' scoring system quantifies the risk of sustaining a pathologic fracture in osseous metastases of weight bearing long bones. Conventional Mirels' scoring is based on radiographs. Our pilot study proposes Tc MDP bone SPECT-CT based modified Mirels' scoring system and its comparison with conventional Mirels' scoring. Cortical lysis was noted in 8(24%) by SPECT-CT versus 2 (6.3%) on X-rays. Additional SPECT-CT parameters were; circumferential involvement [1/4 (31%), 1/2 (3%), 3/4 (37.5%), 4/4 (28%)] and extra-osseous soft tissue [3%]. Our pilot study suggests the potential role of SPECT-CT in predicting risk of fracture in osseous metastases.

Astrophysical polarization measurements in the soft gamma-ray band are becoming more feasible as detectors with high position and energy resolution are deployed. Previous work has shown that the minimum detectable polarization (MDP) of an ideal Compton polarimeter can be improved by ˜21% when an unbinned, maximum likelihood method (MLM) is used instead of the standard approach of fitting a sinusoid to a histogram of azimuthal scattering angles. Here we outline a procedure for implementing this maximum likelihood approach for real, nonideal polarimeters. As an example, we use the recent observation of GRB 160530A with the Compton Spectrometer and Imager. We find that the MDP for this observation is reduced by 20% when the MLM is used instead of the standard method.

One of the obstacles to organ donation and transplantation in Turkey is that of religious beliefs and, at this point, religious officials constitute a key aspect of this problem. Positive or negative viewpoints held by religious officials regarding organ donation and transplantation are influential in guiding the public. This descriptive study was conducted for the purpose of describing religious officials' viewpoints on this subject. To determine the opinions of 40 religious officials from among the imams and muezzins working in Zeytinburnu District Mufti (Religious Officials Superior) Station who participated in a normal meeting in April and who fully completed the survey. A 27-question survey form was used that consisted of open-ended and closed questions, 5 of which were on socio-demographic characteristics, 13 on viewpoints on organ donation and transplantation, and 9 on the Islamic viewpoint regarding organ donation and transplantation. For the analysis of the results, Student's t test and one-way ANOVA tests were used. It was found that all of the religious officials believed in the importance of organ donation, 80 % considered donating their organs, and 5 % had made an organ donation. Of the religious officials who had not donated organs, 35 % gave an answer that there was no specific reason and 27.5 % stated that they had never considered the subject. While the number of those stating that they would donate the organs of a close associate who had died, 77.5 % of them who did not want to donate gave as their reason the idea that if it were him, he would perhaps not want to give his organs after death. Of the religious officials questioned, 92.5 % asserted that the religion of Islam looked positively on organ donation and transplantation, 55 % stated that the knowledge of religious officials in the country was inadequate regarding this subject, and 65 % said that for interest in organ donation to increase, religious officials should make speeches and raise the issue with the public in conversations, meetings, and sermons. Fully 85 % asserted that for interest in organ donation in Turkey to increase, religious officials have to lead on the subject. Of those questioned, 52.5 % considered their knowledge on organ donation and transplantation to be adequate and that they had obtained 52.5 % of such information from seminars/conferences, 50 % from television/radio, and 45 % from Directorate of Religious Affairs publications. However, 40 % expressed that they did not know where organ donations were made. One reason for inadequate organ donation in Turkey is that of incorrect religious beliefs. Thus, it is necessary that informative efforts are made by the Directorate of Religious Affairs through in-house training programs, and that healthcare, religious, and legal officials work jointly to inform the public about organ donation, organ transplantation, and brain death. Additionally, religious officials should donate organs by the way of example and, to increase their sensitivity, healthcare professionals should go more frequently to mosques and Mufti Stations.

Fully 85 % asserted that for interest in organ donation in Turkey to increase, religious officials have to lead on the subject. Of those questioned, 52.5 % considered their knowledge on organ donation and transplantation to be adequate and that they had obtained 52.5 % of such information from seminars/conferences, 50 % from television/radio, and 45 % from Directorate of Religious Affairs publications. However, 40 % expressed that they did not know where organ donations were made. One reason for inadequate organ donation in Turkey is that of incorrect religious beliefs. Thus, it is necessary that informative efforts are made by the Directorate of Religious Affairs through in-house training programs, and that healthcare, religious, and legal officials work jointly to inform the public about organ donation, organ transplantation, and brain death. Additionally, religious officials should donate organs by the way of example and, to increase their sensitivity, healthcare professionals should go more frequently to mosques and Mufti Stations.
Family perspectives on organ and tissue donation for transplantation: a principlist analysis.
Dos Santos, Marcelo José; Feito, Lydia
2017-01-01
The family interview context is permeated by numerous ethical issues which may generate conflicts and impact on organ donation process. This study aims to analyze the family interview process with a focus on principlist bioethics. This exploratory, descriptive study uses a qualitative approach. The speeches were collected using the following prompt: "Talk about the family interview for the donation of organs and tissues for transplantation, from the preparation for the interview to the decision of the family to donate or not." For the treatment of qualitative data, we chose the method of content analysis and categorical thematic analysis. The study involved 18 nurses who worked in three municipal organ procurement organizations in São Paulo, Brazil, and who conducted family interviews for organ donation. Ethical considerations: The data were collected after approval of the study by the Research Ethics Committee of the School of Nursing of the University of São Paulo. The results were classified into four categories and three subcategories. The categories are the principles adopted by principlist bioethics. The principles of autonomy, beneficence, non-maleficence, and justice permeate the family interview and reveal their importance in the organs and tissues donation process for transplantation. The analysis of family interviews for the donation of organs and tissues for transplantation with a focus on principlist bioethics indicates that the process involves many ethical considerations. The elucidation of these aspects contributes to the discussion, training, and improvement of professionals, whether nurses or not, who work in organ procurement organizations and can improve the curriculum of existing training programs for transplant coordinators who pursue ethics in donation and transplantation as their foundation.

Objectives Proper awareness among health professionals about organ donation is important for increasing organ procurement. Personal commitment and attitude of nurses are imperative as they have key role in identifying potential donors. The aim of this study was to compare prevailing knowledge and attitude of undergraduate female Saudi nursing and medical students’ toward organ donation. Methodology A cross sectional questionnaire using 29 item were filled by nursing (n=46) and medical (n=63) students’ at University of Dammam (KSA) during academic year 2014–15, to check and compare their knowledge and attitude about organ donation. The data were analyzed by descriptive statistics; chi square test and bivariate analysis to find out correlation. Results Level of knowledge of nursing group were significantly lower (p=0.000) than medical group while no significant difference in attitude score (p=0.591) between the two groups were found. Major source of knowledge for nursing was media (65.2%) and college/university for medical (50.8%) group. Both groups chose “anyone in need” as preferred recipients’ upon donation (nursing 60.3% and medical 52.2%) and opted “anyone” as donor in case of recipient (nursing 52.2% and medical 49.2%). The results indicate positive correlation between level of knowledge and attitude toward organ donation. Conclusions Nursing students have low knowledge toward organ donation as compared to medical students although they shows positive attitude toward this issue. This study ascertains the need of an effective educational program for nursing students of Saudi Arabia to improve their knowledge regarding organ donation and to raise organ procurement.

Background and Objectives: The blood donor system in the Kingdom of Saudi Arabia depends on a combination of voluntary and involuntary donors. The aim of this study is to explore the attitudes, beliefs and motivations of Saudis toward blood donation. Materials and Methods: The study was conducted at the Donor Centers at King Khalid University Hospital (KKUH) Blood Bank and King Saud University Students Health Center, Riyadh. A self-administered questionnaire was distributed to donors (n = 517) and nondonors (n = 316), between February and June 2008. All were males. Results: Ninety-nine percent of the respondents showed positive attitude toward blood donations and its importance for patients care, and object the importation of blood from abroad. Blood donors: Ninety-one percent agree that that blood donation is a religious obligation, 91% think no compensation should be given, 63% will accept a token gift, 34% do not object to donating six times/year and 67% did not mind coming themselves to the donor center to give blood. Nondonors: Forty-six percent were not asked to give blood and those who were asked mentioned fear (5%) and lack of time (16%) as their main deterrents. Reasons for rejection as donors include underweight and age (71%) and health reasons (19%). Seventy-five percent objected to money compensation but 69% will accept token gifts and 92% will donate if a relative/friend needs blood. Conclusion: These results reflect an encouraging strong positive attitude toward blood donation. Further future planning with emphasis on educational/publicity programs and careful organization of donor recruitment campaigns could see the dream of total voluntary nonremunerated blood donations should not take long to be true.

The National Breast and Cervical Cancer Early Detection Program (NBCCEDP) is the largest cancer screening program for low-income women in the United States. This study updates previous estimates of the costs of delivering preventive cancer screening services in the NBCCEDP. We developed a standardized web-based cost-assessment tool to collect annual activity-based cost data on screening for breast and cervical cancer in the NBCCEDP. Data were collected from 63 of the 66 programs that received funding from the Centers for Disease Control and Prevention during the 2006/2007 fiscal year. We used these data to calculate costs of delivering preventive public health services in the program. We estimated the total cost of all NBCCEDP services to be $296 (standard deviation [SD], $123) per woman served (including the estimated value of in-kind donations, which constituted approximately 15% of this total estimated cost). The estimated cost of screening and diagnostic services was $145 (SD, $38) per women served, which represented 57.7% of the total cost excluding the value of in-kind donations. Including the value of in-kind donations, the weighted mean cost of screening a woman for breast cancer was $110 with an office visit and $88 without, the weighted mean cost of a diagnostic procedure was $401, and the weighted mean cost per breast cancer detected was $35,480. For cervical cancer, the corresponding cost estimates were $61, $21, $415, and $18,995, respectively. These NBCCEDP cost estimates may help policy makers in planning and implementing future costs for various potential changes to the program. © 2014 American Cancer Society.

Willingness to donate blood samples for genetic research: a survey from a community in Singapore.
Wong, M L; Chia, K S; Yam, W M; Teodoro, G R; Lau, K W
2004-01-01
Studies on the public's willingness to donate blood specimens for genetic research are few and are conducted mainly among Western countries. Little is known about the Asian community's willingness to participate in genetic research. A community-based survey was conducted on 548 adult Singaporeans to examine their willingness to donate blood samples for genetic research and its associated factors. The response rate was 70.3%. About 49.3% (95% CI, 45.1-53.5%) were willing to donate blood for genetic research. In the multivariable Cox regression analysis, willingness was significantly associated with belief in the benefits of genetic research; intention to participate in government studies; having no fear of pain, blood, injections, and needles; and non-concern about the loss of confidentiality. Reasons against donating blood were fear of pain, blood, injections, and needles (38.1%); no self-benefits (24.8%); fear of finding out about having a disease (22.3%); fear of discrimination (18.7%); and concerns about weakness (15.1%) and weight gain (9.4%). Public education programs to promote participation in genetic research should stress its benefits and address people's fears and concerns.

Brexit may lead to major political, societal, and financial changes-this has significant implications for a tax revenue funded healthcare system such as the United Kingdom's (UK) National Health Service. The complex relationship between European Union (EU) legislation and clinical practice of organ donation and transplantation is poorly understood. However, it is unclear what impact Brexit may have on organ donation and transplantation in the UK and EU. This work aims to describe the current legislative interactions affecting organ donation and transplantation regulation and governance within the UK and EU. We consider the potential impact of Brexit on the practical aspects of transplantation such organ-sharing networks, logistics, and the provision of health care for transplant patients when traveling to the EU from the UK and vice versa, as well as personnel, and research. Successful organ donation and transplantation practices rely on close collaboration and co-operation across Europe and throughout the United Kingdom. The continuation of such relationships, despite the proposed legislative change, will remain a vital and necessary component for the ongoing success of transplantation programs. © 2018 The Authors.

The Human Organ Preservation Effort is a government organ procurement organization that pioneered the Deceased Organ Donation Program in the Philippines. Deceased organ donation comprises only 20% of kidney transplantation in the Philippines in the last 3 years. Various measures were implemented to improve deceased organ donor referrals and organ retrieval. To compare outcome of deceased organ donor referrals from 2002 to 2008 and 2009 to 2012 in the Philippines. This retrospective study reviewed the deceased organ donor referrals from 2002 to 2008 and 2009 to 2012. There were 437 referrals for potential deceased organ donors from 2009 to 2012, compared to 434 referrals from 2002 to 2008. Referrals were mainly trauma victims (76%) followed by those with cerebrovascular accidents (12%). In the recent cohort, 81% were approached and 60% consented for donation, but only 23% were retrieved and transplanted. Among those not retrieved, the majority (19%) were medically unsuitable and 6% retracted their consent. Although there was an increasing trend of organ donation referrals in the last 4 years, only 25% were procured. The reasons for nonprocurement should be addressed. Copyright © 2014 Elsevier Inc.

We report the views of 33 women who were involved in an altruistic oocyte donation program about provisions under Canada's Assisted Human Reproduction Act 2004 to prohibit donor compensation and to establish a Personal Health Information Registry. The participants had been either donors of oocytes to a recipient known to them (15) or recipients of such donation (18) through services provided by a clinic in a large Canadian city, and they each participated in a semi-structured face-to-face or telephone interview. Among the 15 donor participants, seven were friends of the recipient, six were sisters, one was a niece of the recipient, and one donor donated twice, once to her sister and once to a friend. In eight cases the donor and recipient participated in interviews independently. At the time of interview, 11 of the 25 separate cases had resulted in a live birth and one in an ongoing pregnancy, so that "successful" and "unsuccessful" donations were equally represented among participants. While divergent views were reported among and between donors and recipients on an altruistic model versus a compensated model of donation, most participants largely endorsed the establishment of a personal health information registry.

West Nile virus among blood donors in the United States, 2003 and 2004.
Stramer, Susan L; Fang, Chyang T; Foster, Gregory A; Wagner, Annette G; Brodsky, Jaye P; Dodd, Roger Y

West Nile virus first appeared in the United States in 1999 and has since spread throughout the contiguous states, resulting in thousands of cases of disease. By 2002, it was clear that the virus could be transmitted by blood transfusion, and by the middle of 2003, essentially all blood donations were being tested for West Nile virus RNA with the use of investigational nucleic acid amplification tests; testing was performed on individual samples or on "minipools" of up to 16 donations. We analyzed data from the West Nile virus testing program of the American Red Cross for 2003 and 2004 to identify geographic and temporal trends. In areas with a high incidence of infection, individual donations were tested to increase the sensitivity of testing. Donors with reactive results participated in follow-up studies to confirm the original reactivity and to assess the natural history of infection. Routine testing in 2003 and 2004 identified 540 donations that were positive for West Nile virus RNA, of which 362 (67 percent) were IgM-antibody-negative and most likely infectious. Of the 540 positive donations, 148 (27 percent) were detectable only by testing of individual donations, but only 15 of the 148 (10 percent) were negative for IgM antibody. The overall frequencies of RNA-positive donations during the epidemic periods were 1.49 per 10,000 donations in 2003 and 0.44 per 10,000 in 2004. In 2004, 52 percent of the positive donations were from donors in four counties in southern California. Rapid implementation of a nucleic acid amplification test led to the prospective identification of 519 donors who were positive for West Nile virus RNA and the removal of more than 1000 potentially infectious related components from the blood supply of the Red Cross. No cases of transfusion-transmitted infection were confirmed among recipients of the tested blood. Copyright 2005 Massachusetts Medical Society.

In 2011, a pilot program for deceased organ donation was initiated in China. We describe the first successful series of liver transplants in the pilot program. From July 2011 to August 2012, our center performed 26 liver transplants from a pool of 29 deceased donors. All organ donation and allograft procurement were conducted according to the national protocol. The clinical data of donors and recipients were collected and summarized retrospectively. Among the 29 donors, 24 were China Category II donors (organ donation after cardiac death), and five were China Category III donors (organ donation after brain death followed by cardiac death). The recipients were mainly the patients with hepatocellular carcinoma. The one-year patient survival rate was 80.8% with a median follow-up of 422 (2-696) days. Among the five mortalities during the follow-up, three died of tumor recurrence. In terms of post-transplant complications, 9 recipients (34.6%) experienced early allograft dysfunction, 1 (3.8%) had non-anastomotic biliary stricture, and 1 (3.8%) was complicated with hepatic arterial thrombosis. None of these complications resulted in patient death. Notably, primary non-function was not observed in any of the grafts. With careful donor selection, liver transplant from deceased donors can be performed safely and plays a critical role in overcoming the extreme organ shortage in China.

As the need for the organ donation increases, strategies to increase kidney transplantation (KT) through expanded living donation have become essential. These include kidney paired donation (KPD) programs and desensitization in incompatible transplantations. KPD enables kidney transplant candidates with incompatible living donors to join a registry with other incompatible pairs in order to find potentially compatible living donor. Positive cross match and ABO incompatible transplantation has been successfully accomplished in selective cases with several pre-conditionings. Patients who are both difficult-to-match due to broad sensitization and hard-to-desensitize because of donor conditions can often be successfully transplanted through a combination of KPD and desensitization. According to the existing data, KPD can increase the number of KTs from living donors with excellent clinical results. This is also a cost-effective treatment as compared with dialysis and desensitization protocols. We carried out 3-way KPD transplantation with one highly sensitized, positive cross match pair and with two ABO incompatible pairs. Herein we report our first successful 3-way KPD transplantation in a single center. To maximize donor-recipient matching and minimize immunologic risk, KPD programs should use proper algorithms with desensitization to identify optimal donor with simultaneous two-, three- or more complex multi-way exchanges. © 2018 The Korean Academy of Medical Sciences.

Understanding factors that encourage different racial and ethnic groups to donate is crucial for donor recruitment and retention. A 28-item self-administered questionnaire was completed in 2003 by 1862 Asian, 1479 black, 1641 Hispanic, and 2940 White US donors who had given whole blood within the past year. With a 1 to 5 scale, donors were asked to rate the importance of 17 factors in their last donation decision. Logistic regression was conducted to compare the odds of a factor being important or very important (score of 4 or 5) in one's decision to donate between race or ethnic groups, stratified by first-time and repeat status. More than 90 percent of each respondent group cited a desire, responsibility, or perceived duty to help others as an important or very important motivator. Being asked to donate at work was also an important motivator for all race and ethnic groups (56-70%). Getting the results of a health screen appealed to many (approx. 30% found it important or very important) and was most important to Black and Hispanic donors (odds ratios of 1.3-1.9 compared to White donors; p<0.003). Recruitment and retention programs should build on people's sense of social responsibility. Direct requests to donate are particularly effective motivators. Of a variety of incentives evaluated, offering more comprehensive health screens may motivate many donors, especially Black and Hispanic donors.

Lactating women in the United States have several options for what they do with excess breast milk, including donating to milk banks that serve medically fragile infants, sharing directly with families seeking milk, and selling to individuals or for-profit entities. The World Health Organization and the US Surgeon General have issued calls to increase access to pasteurized donor milk for medically fragile infants. To explore how lactating women with a surplus of breast milk come to the decision to share their milk with a peer rather than donate to a milk bank. A qualitative design using a grounded theory approach was employed. Semistructured telephone interviews were conducted with 27 women who had shared milk with a peer but not with a milk bank. Five dominant themes were identified: a strong belief in the value of breast milk, unexpected versus planned donation, sources of information regarding milk exchange, concerns and knowledge gaps about milk banks, and helping and connecting. This research offers insights into potential strategies for promoting milk bank donation among peer-to-peer milk sharers, including developing donor education campaigns focused on knowledge gaps regarding milk banks and developing health care professional referral programs that can reduce barriers associated with the convenience of milk bank donation. © The Author(s) 2016.
[Blood donation in urban areas].
Charpentier, F
2013-05-01
Medical and technical developments increase the difficulty to provide sufficient safe blood for all patients in developed countries and their sociodemographic and societal changes. Sufficient national blood supply remains a reached, however still actual, challenge. Tomorrow is prepared today: the management of blood donation programs both in line with these developments and with social marketing strategies is one of the keys to success. If the main components of this organization are well known (mobile blood drives in various appropriate environments, and permanent blood donation centers) their proportions in the whole process must evolve and their contents require adaptations, especially for whole blood donation in urban areas. We have to focus on the people's way of life changes related to increasing urbanization of the society and prominent position taken by very large cities. This requires targeting several goals: to draw the attention of the potential blood-giving candidate, to get into position to collect him when he will decide it, to give meaning and recognition to his "sacrifice" (give time rather than donate blood) and to give him desire and opportunity to come back and donate one more time. In this strategy, permanent blood centers in urban areas have significant potential for whole blood collection, highlighted by the decrease of apheresis technology requirements. This potential requires profound changes in their location, conception and organization. The concept of Maison Du Don (MDD) reflects these changes. Copyright © 2013. Published by Elsevier SAS.
Current status of in-hospital donation coordinators in Japan: nationwide survey.

When the Japanese Organ Transplantation Act was issued, the Japanese Organ Transplantation Network (JOT) was established in 1997. JOT lists recipients, assesses and manages organ donors, and educates publics and headquarters for organ donations. JOT procurement transplant coordinators (PTC) play roles in obtaining consent from relatives for organ donation, donor evaluation and management, organ recovery management, organ transport, and care of donor families during and after donation. Every prefecture has at least one PTC who is mainly working in public education and hospital development. They also help the JOT PTC at the time of organ procurement. Most prefectures commission hospital staff in the procurement hospital to be an in-hospital PTC (In-Hp PTC), who make their hospital staff aware of organ donation and support organ procurement. Although the Act was revised in 2010 with brain-dead organ donation increased from 13 to 44 cases yearly, the number was still extremely smaller than other developed countries. In these circumstances, In-Hp PTC may play greater roles to increase donation and smooth procurement procedures Our primary aim was to describe the current status of In-Hp PTC in Japan. Between December 15, 2011, and January 31, 2012, we invited 1889 In-Hp PTC to complete a letter survey using a self-designed questionnaire. In all, 56 In-Hp PTC (40%) completed and returned it. The occupation of the respondents was nurse (66%), physician (18%), or other (16%). Although 52% of respondents belonged to the hospital, which was designated for brain-death organ donation by the government, only 46% had any experience with a cadaveric donor. Only 2% were full-time In-Hp PTC. They mainly played a role in preparing their own manual for organ procurement (57%), providing in-hospital lectures (44%) or their own simulation exercise (29%), as well as coordinating donation cases. Although 77% had attended seminar about organ donation provided by JOT or the prefecture PTC, 93% wanted more professional education. However, it was difficult for them to attend these activities, to manage a rare and sudden donation case, and to find time to learn about organ donation because they had another post. The topics that they wanted to learn were donor family care (72%), overall organ/tissue donation procedures (65%), the role of In-Hp PTC (67%), simulations of donation (65%), legislation and social system of organ donation (61%), medical indications for donation (61%), current status of donation and transplantation in Japan (57%), donor management (56%), and case studies (49%). There were significant variations in the topics of interest among the occupations. As they had another post, they could find only a short period (1 or 2 days) to take professional education, such as lectures. Therefore, it was difficult for them to attend practical on-the-job training. To establish an organ procurement system and increase organ donation, In-Hp PTC have important roles in Japan. However, none is a full-time In-Hp PTC. Most In-Hp PTC require more professional education. A systematic education program for each occupation must be established soon. Copyright © 2013 Elsevier Inc.

Lung transplant of extrahospitalary donor after cardiac death.
Mateos Rodríguez, Alonso A; Navalpotro Pascual, José Maria; del Río Gallegos, Francisco
2013-04-01
Non-heart-beating donors (NHBDs) have to meet the predefined criteria for organ donation including death from irreversible cessation of the beating heart. The Maastricht conference defined 4 NHBD categories to differentiate their viability and ethical-legal support. In Spain, NHBDs who originate from an out-of-hospital setting correspond to type II donors. These are patients who have had a cardiac arrest outside hospital and, after failed CPR attempts, are transferred with hemodynamic support measures to the hospital for organ donation. The Hospital Clínico San Carlos also has a lung donation program in collaboration with the Hospital Puerta de Hierro in Madrid and the Hospital Marques de Valdecilla in Santander. The objective of this study is to describe the results of lung transplantation of after cardiac death program, specifically the section regarding lung extraction donation. Twenty potential lung donors were obtained during the study. Most patients were male (19 cases), with a mean age of 42 years (36.5-49.5 years). A total of 33 lungs were donated (18 right and 15 left lungs). Most extractions were multiorganic (19 cases). One liver, 19 kidneys, 2 pancreas, and 19 corneas were obtained from these donors; bone tissue was obtained from all donors. The transplantation was bipulmonary in 13 cases and unipulmonary in 7. Thirty days after transplantation, 2 recipients died, 1 died of stroke associated with bilateral pneumonia and 1 died of hypovolemic shock resulting from hemothorax. The remaining 18 patients were progressing well at 30 days. Our data suggest that lung transplantation from patients after extrahospitalary cardiac death is feasible. Copyright © 2013 Elsevier Inc.

African Americans comprise 11 % of living organ donors, yet constitute 34 % of the kidney transplant waiting list. There are many barriers to organ donation among minorities that include decreased awareness of transplantation, cultural mistrust of the medical community, financial concerns, and fear of the transplant operation. This study investigates the societal misconceptions and demographic health factors that correlate with minority participation in organ and tissue donation. A 57 question Health and Wellness survey was designed to assess participants' demographic information, medical history, professional background, and opinions regarding organ transplantation. Participants were also asked to complete Quality Metric's Short Form-8 (SF-8) survey to assess physical health, mental health, and quality-of-life. Three hundred twenty-six surveys were administered to minority men. The majority of men were identified as African American, and 55 % were below the age of 40. Though 44 % of participants were willing to donate, only 27 % were registered as organ and tissue donors. Minorities who held misconceptions about organ donation-including the belief that they were too old or unhealthy to donate, for example-had lower general, physical, and mental health scores than those who did not (p = <0.0001). Minorities aware of the shortage for organs or who know a registered donor, an organ recipient, a dialysis patient, or someone on the waiting list were more willing to donate organs. Improving the general, physical, and mental health of minorities, coupled with an active educational outreach program, could result in a greater percentage of minorities registering and willing to be organ and tissue donors.

Interpersonal relations with health care providers influence families' decisions to consent to solid-organ donation. However, previous research has been based on retrospective interviews with donation-eligible families and has not directly examined the interpersonal interactions between families and organ procurement coordinators. To increase understanding of the interpersonal interaction between procurement coordinators and families during the organ donation discussion, with special attention to the influence of the sex and race of the procurement coordinator and the race of the potential donor's family. A descriptive study in which standardized patients portrayed family members interacting with actual procurement coordinators in simulated donation request scenarios. Thirty-three videotaped interactions between standardized patients and 17 procurement coordinators involving 2 different scenarios depicting deceased donation were evaluated. Video recordings were rated by independent coders. Coders completed the Impact Message Inventory-Form C, the Participatory Style of Physician Scale, and the Siminoff Communication and Content and Affect Program-Global Observer Ratings scale. African American procurement coordinators, particularly African American women, were rated as more controlling and work-oriented than white procurement coordinators. Male procurement coordinators were more affiliative with the white family than the African American family, whereas female procurement coordinators were slightly less affiliative with the white family. African American procurement coordinators expressed more positive affect when interacting with the African American family than the white family, whereas the opposite was true for white procurement coordinators. Research is needed to cross-validate these exploratory findings and further examine cultural mistrust between procurement coordinators and families of ethnic minorities, especially given the negative attitudes of many minorities toward donation.

Sudeck's atrophy of the foot is an acute, patchy osteoporosis that, on bone scan, shows an increase in both bone blood flow and local bone uptake of bone-seeking radionuclides. The purpose of this study was to evaluate the relationship between bone uptake of 99mTc-MDP and local bone blood flow. In some patients with Sudeck's atrophy of one foot we measured local bone blood flow and bone uptake of 99mTc-MDP. External counting of radioactivity, with a count-rate of 1 second was performed for 60 minutes after i.v. injection of a known dose of 99mTc-MDP in some patients with Sudeck's atrophy of the foot. The regions of interest (ROI) were selected on the basis of a bone scan performed 24 hours earlier. We assumed that the data recorded during the first seconds (7-10) reflect local blood flow and the data at 60 minutes reflect the bone uptake. The ratio between the local blood flow in the involved and healthy foot was higher than the local bone uptake ratio. The ratio between bone uptake and local bone blood flow was higher in the normal foot than in the affected one. These results suggest that the bone avidity for bone-seeking radionuclides is lower in Sudeck's atrophy than in normal bone.

The purpose of this study was to compare estimation of radiation absorbed doses to patients following bone scans with technetium-99m-labeled methylene diphosphonate (MDP) with the estimates given in MIRDose software. In this study, each patient was injected 25 mCi of 99mTc-MDP. Whole-body images from thirty patients were acquired by gamma camera at 10, 60, 90, 180 minutes after 99mTc-MDP injection. To determine the amount of activity in each organ, conjugate view method was applied on images. MIRD equation was then used to estimate absorbed doses in different organs of patients. At the end, absorbed dose values obtained in this study were compared with the data of MIRDose software. The absorbed doses per unit of injected activity (mGy/MBq × 10–4) for liver, kidneys, bladder wall and spleen were 3.86 ± 1.1, 38.73 ± 4.7, 4.16 ± 1.8 and 3.91 ± 1.3, respectively. The results of this study may be useful to estimate the amount of activity that can be administered to the patient and also showed that methods used in the study for absorbed dose calculation is in good agreement with the data of MIRDose software and it is possible to use by a clinician.

This study focuses on the analysis of the nonstationarity characteristics of extreme precipitation and their attributions in the southeastern coastal region of China. The maximum daily precipitation (MDP) series is extracted from observations at 79 meteorological stations in the study area during the first flood season (April-June) from 1960 to 2012. The trends of the mean (Mn) and variance (Var) of MDP are detected using the Generalized Additive Models for Location, Scale, and Shape parameters (GAMLSS) and Mann-Kendall test. The contributions of natural climate change and human activities to the Mn and Var changes of MDP are investigated using six large-scale circulation variables and emissions of four greenhouse gases based on GAMLSS and a contribution analysis method. The results demonstrate that the nonstationarity of extreme precipitation on local scales is significant. The Mn and Var of extreme precipitation increase in the north of Zhejiang, the middle of Fujian, and the south of Guangdong. In general, natural climate change contributes more to Mn from 1960 to 2012 than to Var. However, human activities cause a greater Var in the rapid socioeconomic development period (1986-2012) than in the slow socioeconomic development period (1960-1985), especially in Zhejiang and Guangdong. The community should pay more attention to the possibility of extreme precipitation events and associated disasters triggered by human activities.
Study of radial die-wall pressure changes during pharmaceutical powder compaction.

In tablet manufacturing, less attention is paid to the measurement of die-wall pressure than to force-displacement diagrams. Therefore, the aim of this study was to investigate radial stress change during pharmaceutical compaction. The Presster(TM), a tablet-press replicator, was used to characterize compaction behavior of microcrystalline cellulose (viscoelastic), calcium hydrogen phosphate dihydrate (brittle), direct compressible mannitol (plastic), pre-gelatinized starch (plastic/elastic), and spray dried lactose monohydrate (plastic/brittle) by measuring radial die-wall pressure; therefore powders were compacted at different (pre) compaction pressures as well as different speeds. Residual die-wall pressure (RDP) and maximum die-wall pressure (MDP) were measured. Various tablet physical properties were correlated to radial die-wall pressure. With increasing compaction pressure, RDP and MDP (P < 0.0001) increased for all materials, with increasing precompaction RDP decreased for plastic materials (P < 0.05), whereas with increasing speed MDP decreased for all materials (P < 0.05). During decompression, microcrystalline cellulose and pre-gelatinized starch showed higher axial relaxation, whereas mannitol and lactose showed higher radial relaxation, calcium hydrogen phosphate showed high axial and radial relaxations. Plastic and brittle materials showed increased tendencies for friction because of high radial relaxation. Die-wall monitoring is suggested as a valuable tool for characterizing compaction behavior of materials and detecting friction phenomena in the early stage of development.
Structural abnormality of the corticospinal tract in major depressive disorder
2014-01-01
Background Scientists are beginning to document abnormalities in white matter connectivity in major depressive disorder (MDD). Recent developments in diffusion-weighted image analyses, including tractography clustering methods, may yield improved characterization of these white matter abnormalities in MDD. In this study, we acquired diffusion-weighted imaging data from MDD participants and matched healthy controls. We analyzed these data using two tractography clustering methods: automated fiber quantification (AFQ) and the maximum density path (MDP) procedure. We used AFQ to compare fractional anisotropy (FA; an index of water diffusion) in these two groups across major white matter tracts. Subsequently, we used the MDP procedure to compare FA differences in fiber paths related to the abnormalities in major fiber tracts that were identified using AFQ. Results FA was higher in the bilateral corticospinal tracts (CSTs) in MDD (p’s < 0.002). Secondary analyses using the MDP procedure detected primarily increases in FA in the CST-related fiber paths of the bilateral posterior limbs of the internal capsule, right superior corona radiata, and the left external capsule. Conclusions This is the first study to implicate the CST and several related fiber pathways in MDD. These findings suggest important new hypotheses regarding the role of CST abnormalities in MDD, including in relation to explicating CST-related abnormalities to depressive symptoms and RDoC domains and constructs.

Operation Blue, ULTRA: DION--the donation inmate organ network.
Bartz, Clifford Earle
2003-03-01
Presently more than 80,000 Americans await an organ transplant, while 10 to 12 people die each day because of the lack of organs. The program proposed here would allow federal inmates additional "time off" for agreeing to become living donors or to provide organs or their bodies upon death. Such a program could add 100 to 170 thousand new organ donors to the pool, with another 10 to 12 thousand added annually. If the program were applied to all state inmates, up to 4 million new donors might be added, with another 10 to 13 thousand added annually. Given the extreme need for more organ donors and the need for more living donors, the current National Transplant Act of 1984 and the Uniform Anatomical Gift Act must be amended, while still retaining control of donation procedures.
[Changes in the transplantation world--from altruism to a utilitarian approach].
Mor, Eytan
2006-10-01
The lack of organs for transplantation is a worldwide problem that has created a moral conflict between the traditional altruistic basis of organ donation and alternative solutions based on utilitarian grounds. Survival of grafts achieved in recent decades after unrelated living-donor kidney transplantation between spouses is longer than with deceased donor transplantation. This experience justified the extension of kidney donation beyond the traditional close family relationships including: anonymous donors and paired exchange programs. However, unrelated donation of kidneys within altruistic norms could not provide an ultimate solution for the lack of organs for transplantation. On the other hand, globalization and development of advanced medical technology in developing countries that do not provide transplantation for all their citizens, created an opportunity for a worldwide flourish of transplant tourism as an alternative solution for transplant candidates. Transplant tourism functions according to market laws and is profit-driven, as opposed to the legal organ exchange programs in Europe and the U.S.A., which are non-profit and patient-oriented. The transition from trade in kidneys from unrelated living-donors to the use of other organs (heart, lung and liver) from death penalty prisoners in China was only a matter of deciding where to lay the moral border when justifying the act for the sake of life-saving. Considering the inability of current legal altruistic transplantation practice to supply the growing need for organs, healthcare authorities and professional transplantation organizations have to tackle the donor crisis by designing legally acceptable utilitarian solutions. For instance, through the formation of international organ exchange programs under formal agreements or, in the case of kidney transplantation, through the establishment of a regulated compensated donation system.

Background Between 2007 and 2012, Children Without Worms (CWW) oversaw the Johnson & Johnson (J&J) donation of Vermox (mebendazole) for treatment of school-age children to control soil-transmitted helminthiasis (STH). To identify factors associated with on-time, delayed, or missed mass drug administration (MDA) interventions, and explore possible indicators for supply chain performance for drug donation programs, we reviewed program data for the 14 STH-endemic countries CWW supported during 2007–2012. Methodology Data from drug applications, shipping records, and annual treatment reports were tracked using Microsoft Excel. Qualitative data from interviews with key personnel were used to provide additional context on the causes of delayed or missed MDAs. Four possible contributory factors to delayed or missed MDAs were considered: production, shipping, customs clearance, and miscellaneous in-country issues. Coverage rates were calculated by dividing the number of treatments administered by the number of children targeted during the MDA. Principal Findings Of the approved requests for 78 MDAs, 54 MDAs (69%) were successfully implemented during or before the scheduled month. Ten MDAs (13%) were classified as delayed; seven of these were delayed by one month or less. An additional 14 MDAs (18%) were classified as missed. For the 64 on-time or delayed MDAs, the mean coverage was approximately 88%. Conclusions and Significance To continue to assess the supply chain processes and identify areas for improvement, we identified four indicators or metrics for supply chain performance that can be applied across all neglected tropical disease (NTD) drug donation programs: (1) donor having available inventory to satisfy the country request for donation; (2) donor shipping the approved number of doses; (3) shipment arriving at the Central Medical Stores one month in advance of the scheduled MDA date; and (4) country programs implementing the MDA as scheduled.

To study the results of a non-controlled cardiac death (Maastricht type II) donor program in a city of 200,000 inhabitants. The study was initially focused on lung donation and was extended to kidney donation after 9 months. A prospective observational study was conducted between October 2012 and December 2013. The Intensive Care Unit of Marqués de Valdecilla University Hospital in Santander (Spain), and surrounding areas. Patients (< 55 years) who died of out-of-hospital cardiac arrest. All out-of-hospital cardiac arrests were treated with mechanical cardiac compression (LUCAS II). The diagnosis of death and organ preservation were performed in the ICU. A total of 14 calls were received, of which three were discarded. Of the 11 potential donors, 7 were effective donors with a median age of 39.5 years (range: 32-48). A total of 5 single lung transplants and four kidney transplants were performed. In addition, corneas and tissues were harvested. The non-valid donors were rejected mainly due to technical problems. There were no donation refusals on the part of the patient relatives. The lung transplant patient survival rate was 100% after one month and 80% after one year. One month after transplantation, the kidney recipients had a serum creatinine concentration of<2mg/dl. The interval from cardiac arrest to renal preservation was 80minutes (range: 71-89), and the interval from cardiac arrest to lung preservation was 84minutes (range: 77-94). A Maastricht type II donation program in a small city is viable for both abdominal and thoracic organs. The program was initially very cautious, but its potential is easily improvable by increasing donor and by equipping mobile ICU ambulances with mechanical cardiac compression systems. Full management of the donor in the ICU, avoiding the emergency department or operating rooms, reduces the warm ischemia time, thereby improving transplant outcomes.

A case of unilateral nearly total hypoperfusion of the left lung in a 13-month-old girl is presented. The combination of the lung hypoperfusion and accumulation of the Tc-99m MDP and Ga-67 citrate in the same area suggested the preoperative diagnosis of mediastinal neuroblastoma. Explorative thoracotomy revealed the presence of a neuroblastoma compressing the left lung pedicle. The described scintigraphic appearance in the pediatric age group is suggested as typical of mediastinal neuroblastoma. This pathology should be included in the following gamuts in nuclear medicine: unilateral decrease or absent lung perfusion, unilateral diffuse chest uptake of Ga-67 citrate, and unilateral pulmonarymore » uptake in bone scintigraphy.« less

Astrophysical polarization measurements in the soft gamma-ray band are becoming more feasible as detectors with high position and energy resolution are deployed. Previous work has shown that the minimum detectable polarization (MDP) of an ideal Compton polarimeter can be improved by ∼21% when an unbinned, maximum likelihood method (MLM) is used instead of the standard approach of fitting a sinusoid to a histogram of azimuthal scattering angles. Here we outline a procedure for implementing this maximum likelihood approach for real, nonideal polarimeters. As an example, we use the recent observation of GRB 160530A with the Compton Spectrometer and Imager. Wemore » find that the MDP for this observation is reduced by 20% when the MLM is used instead of the standard method.« less
Cardiac transplantation. Organ procurement to patient discharge.
Rudolphi, D M; Nagy, K M; Verne, D J
1987-01-01
The care of the cardiac transplant patient is complex, yet rewarding. During the hospital stay, the patients, families, and nurses develop close-knit relationships that last after discharge. The cardiac transplant patients at Hershey Medical Center have formed a support group. To promote organ donation, they wear T-shirts, hats, and coats with the logo, "I got my heart at HMC," (Hershey Medical Center). This not only increases awareness of the need for organ donation, but also gives Hershey Medical Center recognition for its cardiac transplantation program.

Babesia microti, a tickborne intraerythrocytic parasite that can be transmitted by means of blood transfusion, is responsible for the majority of cases of transfusion-transmitted babesiosis in the United States. However, no licensed test exists for screening for B. microti in donated blood. We assessed data from a large-scale, investigational product-release screening and donor follow-up program. From June 2012 through September 2014, we performed arrayed fluorescence immunoassays (AFIAs) for B. microti antibodies and real-time polymerase-chain-reaction (PCR) assays for B. microti DNA on blood-donation samples obtained in Connecticut, Massachusetts, Minnesota, and Wisconsin. We determined parasite loads with the use of quantitative PCR testing and assessed infectivity by means of the inoculation of hamsters and the subsequent examination for parasitemia. Donors with test-reactive samples were followed. Using data on cases of transfusion-transmitted babesiosis, we compared the proportions of screened versus unscreened donations that were infectious. Of 89,153 blood-donation samples tested, 335 (0.38%) were confirmed to be positive, of which 67 (20%) were PCR-positive; 9 samples were antibody-negative (i.e., 1 antibody-negative sample per 9906 screened samples), representing 13% of all PCR-positive samples. PCR-positive samples were identified all through the year; antibody-negative infections occurred from June through September. Approximately one third of the red-cell samples from PCR-positive or high-titer AFIA-positive donations infected hamsters. Follow-up showed DNA clearance in 86% of the donors but antibody seroreversion in 8% after 1 year. In Connecticut and Massachusetts, no reported cases of transfusion-transmitted babesiosis were associated with screened donations (i.e., 0 cases per 75,331 screened donations), as compared with 14 cases per 253,031 unscreened donations (i.e., 1 case per 18,074 unscreened donations) (odds ratio, 8.6; 95% confidence interval, 0.51 to 144; P=0.05). Overall, 29 cases of transfusion-transmitted babesiosis were linked to blood from infected donors, including blood obtained from 10 donors whose samples tested positive on the PCR assay 2 to 7 months after the implicated donation. Blood-donation screening for antibodies to and DNA from B. microti was associated with a decrease in the risk of transfusion-transmitted babesiosis.

Organ and tissue donation: are minorities willing to donate?
Daniels, D E; Smith, K; Parks-Thomas, T; Gibbs, D; Robinson, J
1998-01-01
The Task Force on Organ Transplantation (DHHS,1986) addressed the issue of increasing organ donation. The Report of the Task Force recommended that "educational efforts aimed at increasing organ donation among minority populations be developed and implemented, so that the donor population will more closely reflect the ethnicity of potential transplant recipients, in order to gain the advantage of improved donor and recipient immunologic matching (DHHS,1986). Donor rates for minorities has increased as follows: 16% in 1988 to 23% in 1995 among cadaveric donors and 24% in 1988 to 28% in 1995 among living donors. The improvement in donor rates among minorities may positively affect the transplantation success rate experienced by organ recipients of the same race. Strategies must be implemented that will increase the effectiveness and frequency of communication between minority patients and the medical community. An increase in the effectiveness of communication between potential minority donor families and the health care community will contribute to the process of Consciousness Raising as discussed by Prochasksa. The result of increased awareness of the organ donation and transplantation process may have a favorable impact on organ donation. The media has, through public service announcements, paid advertising and entertainment programming, attempted to promote discussion of organ donation in the community and within families. Johnson et al. discussed Mexican-American and Anglo-American Attitudes Toward Organ Donation. The primary impediment contributing to the disparity of consent rates between Mexican-American and Anglo-American population occurs with regard to the donation of organs of relatives. Johnson stated that this impediment to organ donation can be effectively addressed by promoting family discussion. Communication within families will inform surviving next of kin of the desire of the deceased to be an organ donor and hence improve the likelihood of the donor family consenting to organ donation (Johnson et al., 1988). The promotion of communication within families must continue to be a goal of the transplant community regardless of race/ethnicity. Despite the efforts of the government, the transplant community, the media and the corporate sector to address the critical shortage of donors in the United States, the reality is that no community has the supply of donor organs suitable to meet the need.

FPA withdraws from CSM project in Guatemala.
1984-01-01
Guatemala's family planning association, the Asociacion Pro-Bienestar de la Familia (APROFAM) recently cut its ties with the nation's contraceptive social marketing program. The announced reasons for the disassociation was APROFAM's concerns about the legality of selling donated commodities. APROFAM helped create the program served as a member of the marketing program's board of directors, and was expected to function as the channel for the commidities donated by the US Agency for International Development (USAID). The marketing program will now be managed by the newly created Importadora de Farmaceuticos (IPROFA), a for-profit organization. This alters the legal status of the marketing program, and as a result, the program will be required to pay duties on USAID donated contraceptives. USAID cannot legally pay duties on its own contributions. Instead, the duies will be paid by IPROFA out of the revenues generated by the project. IPROFA will finance the 1st consignment of products with a bank loan, and the loan and duties on subsequent shipments will be paid out of the program's revenues. This strategy is not expected to pose legal problems for USAID, since the agency has no control over how programs use the revenues generated by selling the agency's commodities. As a result of the changed status, the marketing program must acquire it own storage and packaging facilities. According to Manuel DeLucca, the program's resident advisor, these problems will not delay the launch of the program's products scheduled for early 1985. The program plans to sell an oral contraceptive, a vaginal spermicidal tablet, and a condom. Orginal plans called for selling the low dose OC, Norminest; however, Norminest may not be approved for distribution in Guatemala, and USAID may replace Norminest with another product. As a result, the program may market Noriday, a normal dose pill instead of Norminest. Guatemalan registration of the spermicidal tablet the program is planning to sell is pending. The program is engendering considerable interest because of its unique legal status as a commercial enterprise and its freedom from bureaucractic constraints.

BACKGROUND The National Breast and Cervical Cancer Early Detection Program (NBCCEDP) is the largest cancer screening program for low-income women in the United States. This study updates previous estimates of the costs of delivering preventive cancer screening services in the NBCCEDP. METHODS We developed a standardized web-based cost-assessment tool to collect annual activity-based cost data on screening for breast and cervical cancer in the NBCCEDP. Data were collected from 63 of the 66 programs that received funding from the Centers for Disease Control and Prevention during the 2006/2007 fiscal year. We used these data to calculate costs of delivering preventive public health services in the program. RESULTS We estimated the total cost of all NBCCEDP services to be $296 (standard deviation [SD], $123) per woman served (including the estimated value of in-kind donations, which constituted approximately 15% of this total estimated cost). The estimated cost of screening and diagnostic services was $145 (SD, $38) per women served, which represented 57.7% of the total cost excluding the value of in-kind donations. Including the value of in-kind donations, the weighted mean cost of screening a woman for breast cancer was $110 with an office visit and $88 without, the weighted mean cost of a diagnostic procedure was $401, and the weighted mean cost per breast cancer detected was $35,480. For cervical cancer, the corresponding cost estimates were $61, $21, $415, and $18,995, respectively. CONCLUSIONS These NBCCEDP cost estimates may help policy makers in planning and implementing future costs for various potential changes to the program. PMID:25099904

Low-Cost, Rugged High-Vacuum System
NASA Technical Reports Server (NTRS)
Sorensen, Paul; Kline-Schoder, Robert
2012-01-01
A need exists for miniaturized, rugged, low-cost high-vacuum systems. Recent advances in sensor technology have led to the development of very small mass spectrometer detectors as well as other analytical instruments such as scanning electron microscopes. However, the vacuum systems to support these sensors remain large, heavy, and power-hungry. To meet this need, a miniaturized vacuum system was developed based on a very small, rugged, and inexpensive-to-manufacture molecular drag pump (MDP). The MDP is enabled by a miniature, very-high-speed (200,000 rpm), rugged, low-power, brushless DC motor optimized for wide temperature operation and long life. The key advantages of the pump are reduced cost and improved ruggedness compared to other mechanical hig-hvacuum pumps. The machining of the rotor and stators is very simple compared to that necessary to fabricate rotor and stator blades for other pump designs. Also, the symmetry of the rotor is such that dynamic balancing of the rotor will likely not be necessary. Finally, the number of parts in the unit is cut by nearly a factor of three over competing designs. The new pump forms the heart of a complete vacuum system optimized to support analytical instruments in terrestrial applications and on spacecraft and planetary landers. The MDP achieves high vacuum coupled to a ruggedized diaphragm rough pump. Instead of the relatively complicated rotor and stator blades used in turbomolecular pumps, the rotor in the MDP consists of a simple, smooth cylinder of aluminum. This will turn at approximately 200,000 rpm inside an outer stator housing. The pump stator comprises a cylindrical aluminum housing with one or more specially designed grooves that serve as flow channels. To minimize the length of the pump, the gas is forced down the flow channels of the outer stator to the base of the pump. The gas is then turned and pulled toward the top through a second set of channels cut into an inner stator housing that surrounds the motor. The compressed gas then flows down channels in the motor housing to the exhaust port of the pump. The exhaust port of the pump is connected to a commercially available diaphragm or scroll pump.

Influenza A virus (IAV) is recognized to cause severe pulmonary illnesses in humans, particularly in elderly and children. One of the features associated with IAV infection is an excessive lung inflammation due to an uncontrolled immune response. The nucleotide-binding oligomerization domain 2 (NOD2) receptor is known to recognize ssRNA viruses such as IAV, but its role in the inflammatory process during viral infections remains to be clarified. In a previous report, we have shown that activation of NOD2 with muramyl dipeptide (MDP) significantly reduces both viral loads and lung inflammation and also improves pulmonary function during IAV infection. These findings prompted us to further investigate whether NOD2 receptor may contribute to regulate inflammation during viral infection. In the present study, we show that administration of MDP to mice infected with IAV stimulates the migration of regulatory T (Treg) cells to the lungs. Such a presence of Treg cells was also accompanied with a reduction of neutrophils in the lungs during IAV infection, which correlated, with a significant decrease of Th17 cells. In our model, Treg cell recruitment is dependent of CXCL12 and CCL5 chemokines. Moreover, we show that the presence of Ly6C low patrolling monocytes is required for Treg cells mobilization to the lung of mice treated with MDP. In fact, following monocyte depletion by administration of clodronate liposome, mobilization of Treg cells to the lungs of treated mice was found to occur when circulating Ly6C low monocytes begin to reemerge. In addition, we also detected an increased production of TGF-β, a cytokine contributing to Treg activity when blood Ly6C low monocytes are restored. Together, our results demonstrate that MDP treatment can promote an anti-inflammatory environment through the mobilization of Treg cells to the lung, a mechanism that requires the presence of Ly6C low monocytes during IAV infection. Overall, our results suggest that activation of NOD2 receptor could be an appealing approach to control pulmonary inflammation in patients infected with IAV.
Allocating conservation resources between areas where persistence of a species is uncertain.
McDonald-Madden, Eve; Chadès, Iadine; McCarthy, Michael A; Linkie, Matthew; Possingham, Hugh P
2011-04-01
Research on the allocation of resources to manage threatened species typically assumes that the state of the system is completely observable; for example whether a species is present or not. The majority of this research has converged on modeling problems as Markov decision processes (MDP), which give an optimal strategy driven by the current state of the system being managed. However, the presence of threatened species in an area can be uncertain. Typically, resource allocation among multiple conservation areas has been based on the biggest expected benefit (return on investment) but fails to incorporate the risk of imperfect detection. We provide the first decision-making framework for confronting the trade-off between information and return on investment, and we illustrate the approach for populations of the Sumatran tiger (Panthera tigris sumatrae) in Kerinci Seblat National Park. The problem is posed as a partially observable Markov decision process (POMDP), which extends MDP to incorporate incomplete detection and allows decisions based on our confidence in particular states. POMDP has previously been used for making optimal management decisions for a single population of a threatened species. We extend this work by investigating two populations, enabling us to explore the importance of variation in expected return on investment between populations on how we should act. We compare the performance of optimal strategies derived assuming complete (MDP) and incomplete (POMDP) observability. We find that uncertainty about the presence of a species affects how we should act. Further, we show that assuming full knowledge of a species presence will deliver poorer strategic outcomes than if uncertainty about a species status is explicitly considered. MDP solutions perform up to 90% worse than the POMDP for highly cryptic species, and they only converge in performance when we are certain of observing the species during management: an unlikely scenario for many threatened species. This study illustrates an approach to allocating limited resources to threatened species where the conservation status of the species in different areas is uncertain. The results highlight the importance of including partial observability in future models of optimal species management when the species of concern is cryptic in nature.

Decreased levels or function of nucleotide-binding oligomerization domain 2 (NOD2) are associated with Crohn's disease. NOD2 regulates intestinal inflammation, and also is expressed by human umbilical cord blood-derived mesenchymal stem cells (hUCB-MSCs), to regulate their differentiation. We investigated whether NOD2 is required for the anti-inflammatory activities of MSCs in mice with colitis. Colitis was induced in mice by administration of dextran sulfate sodium or trinitrobenzene sulfonic acid. Mice then were given intraperitoneal injections of NOD2-activated hUCB-MSCs; colon tissues and mesenteric lymph nodes were collected for histologic analyses. A bromodeoxyuridine assay was used to determine the ability of hUCB-MSCs to inhibit proliferation of human mononuclear cells in culture. Administration of hUCB-MSCs reduced the severity of colitis in mice. The anti-inflammatory effects of hUCB-MSCs were greatly increased by activation of NOD2 by its ligand, muramyl dipeptide (MDP). Administration of NOD2-activated hUCB-MSCs increased anti-inflammatory responses in colons of mice, such as production of interleukin (IL)-10 and infiltration by T regulatory cells, and reduced production of inflammatory cytokines. Proliferation of mononuclear cells was inhibited significantly by co-culture with hUCB-MSCs that had been stimulated with MDP. MDP induced prolonged production of prostaglandin (PG)E2 in hUCB-MSCs via the NOD2-RIP2 pathway, which suppressed proliferation of mononuclear cells derived from hUCB. PGE2 produced by hUCB-MSCs in response to MDP increased production of IL-10 and T regulatory cells. In mice, production of PGE2 by MSCs and subsequent production of IL-10 were required to reduce the severity of colitis. Activation of NOD2 is required for the ability of hUCB-MSCs to reduce the severity of colitis in mice. NOD2 signaling increases the ability of these cells to suppress mononuclear cell proliferation by inducing production of PGE2. Copyright © 2013 AGA Institute. Published by Elsevier Inc.

Resin cements are generally preferred for cementation of zirconia ceramics. Resin bonding of zirconia ceramics cannot be done with the same methods of traditional ceramics because zirconia is a silica-free material. In recent years, many methods have been reported in the literature to provide the resin bonding of zirconia ceramics. The purpose of this in vitro study is to evaluate effects of different surface treatments and 10-metacryloxydecyl dihydrogen phosphate (MDP) monomer on shear bond strength between zirconia and resin cement. 120 zirconia specimens were treated as follows: Group I: sandblasting, group II: sandblasting + tribochemical silica coating + silane, group III: sandblasting + Nd:YAG (neodymium: yttrium-aluminum-garnet) laser. One specimen from each group was evaluated under scanning electron microscope (SEM). Specimens in each group were bonded either with conventional resin cement Variolink II or with a MDP containing resin cement Panavia F2.0. Subgroups of bonded specimens were stored in distilled water (37°C) for 24 hours or 14 days. Following water storage shear bond strength test was performed at a crosshead speed of 1 mm/min in a universal test machine. Then statistical analyses were performed. Highest shear bond strength values were observed in group II. No significant difference between group I and III was found when Panavia F2.0 resin cement was used. When Variolink II resin cement was used group III showed significantly higher bond strength than group I. In group I, Panavia F2.0 resin cement showed statistically higher shear bond strength than Variolink II resin cement. In group II no significant difference was found between resin cements. No significant difference was found between specimens stored in 37°C distilled water for 24 hours and 14 days. In group I surface irregularities with sharp edges and grooves were observed. In group II less roughened surface was observed with silica particles. In group III surface microcracks connecting each other were observed. Tribochemical silica coating is an effective method for achieving an acceptable bond between zirconia and resin cement. Use of a MDP monomer containing resin cement increases the bond strength of sandblasted zirconia.

Organ transplantation is the preferred mode of replacement therapy. Currently acceptable 5-year posttransplantation survival rates are 85% for renal grafts, 70% for liver, and 65% for heart. Organ donation, however, remains a significant factor in organ transplantation, as humans are the only possible donors and the numbers of patients on waiting lists remain high. Several factors affect organ transplantation in countries in the Middle East Society for Organ Transplantation (MESOT) region, including inadequate preventive medicine, differing health infrastructures, poor awareness within the medical community and lay public regarding the importance of organ donation and transplantation, a high level of ethnicity, and poor government support of organ transplantation. Moreover, there is lack of team spirit among transplant physicians, a lack of coordination between groups that manage organ procurement and the transplant centers, and a lack of effective health insurance coverage for many persons. Three models of organ donation and transplantation exist in the MESOT region-the Saudi, Iranian, and Pakistani models. Living-organ donation, the most widely practiced form of donation in countries in the MESOT region, includes kidney and partial liver. Cadaveric organ donation has significant potential in the MESOT region. However, numerous obstacles must be overcome in MESOT countries. Resolution of these obstacles will require continuous work on many fronts. Experiences from all sources must be incorporated into new and improved models that can overcome current inadequacies. Solutions will require continued focus within the medical community, steady support from the lay public and religious institutions, as well as governmental assistance.

A BASIC program has been developed for the Hewlett-Packard Model 9845 desk-top computer which allows the creation of blood donor files for subsequent retrieval, update, and correction. A similar modified version was developed for hte HP 9835 Model. This software system has been called BLISS which stands for Blood Information and Security System. In addition to its function as a file management system, BLISS provides warnings before a donation is performed to protect the donor from excessive exposure to radioactivity and DMSO levels, from too frequent of donations of blood, and from adverse reactions. The program can also be usedmore » to select donors who have participated in specific studies and to list the experimental details which have been stored in the file. The BLISS system has been actively utilized at the Naval Blood Research Laboratory in Boston and contains the files of over 750 donors.« less
The Sun Health Research Institute Brain Donation Program: Description and Eexperience, 1987–2007

The Brain Donation Program at Sun Health Research Institute has been in continual operation since 1987, with over 1000 brains banked. The population studied primarily resides in the retirement communities of northwest metropolitan Phoenix, Arizona. The Institute is affiliated with Sun Health, a nonprofit community-owned and operated health care provider. Subjects are enrolled prospectively to allow standardized clinical assessments during life. Funding comes primarily from competitive grants. The Program has made short postmortem brain retrieval a priority, with a 2.75-h median postmortem interval for the entire collection. This maximizes the utility of the resource for molecular studies; frozen tissue from approximately 82% of all cases is suitable for RNA studies. Studies performed in-house have shown that, even with very short postmortem intervals, increasing delays in brain retrieval adversely affect RNA integrity and that cerebrospinal fluid pH increases with postmortem interval but does not predict tissue viability.

The objectives of this study are to describe the mechanism of the program and to present initial donor outcome. This is a descriptive study evaluating the performance of a national program for nondirected kidney donation from living unrelated donors (LURDs) in the Philippines in its 3-year implementation. It explains the mechanism of the program and socioeconomic and clinical profiling of donors. Frequencies and percentages were used to measure donor demographic data, medical follow-up compliance rate, and employment predonation and postdonation. Diagnostic laboratory criteria were required to show donor clinical profiles. In 2002, the local Health Department issued an administrative order to create a National Transplant Ethics Committee (NTEC) to address issues of rampant organ sale and donor exploitation. It also set guidelines and intended to oversee transplantation from LURDs. Salient points to the program are as follows: (1) prohibition of sale; (2) accreditation of transplantation centers; (3) enrollment of waitlisted patients in both deceased donor and nondirected LURD program; (4) ethics committee evaluation of LURDs; (5) creation of a national kidney transplant wait list and live donor registry allowing centralized, nondirected kidney allocation; (6) 10% cap on allocation to foreigners; (7) creation of a kidney donor monitoring unit with free 10-year annual medical follow-up for feedback evaluation on donor outcome; and (8) allowance of gratitudinal gifts such as health and life insurance, reimbursement for lost income, educational plan, and job placement to LURDs run by a foundation. From 2004 to 2006, 695 potential donors enrolled; 97 were accepted and deemed medically fit to donate. The remaining 598 were rejected due to demand for outright sale (103), medical unsuitability (77), disapproval by the Ethics Committee (12), and retracted consent (406). Of the 97 qualified donors, 79 had donated, 9 were being evaluated, and 9 await allocation at the end of 2006. Donor demographics show the following: 54% (381) single, 77% (538) males, and 70% (488) aged 21-40 years old. Sixty-eight of 79 became small-scale entrepreneurs postdonation. Also, 53% (42 of 79) complied with medical follow-up requirements. Mean serum creatinine level at 6 months, 1 years, and 2 years were 1.3, 1.33, and 1.05 mg/dL, respectively. Two donors had trace protein and 1 had (+1) protein. The majority of the donors are single males, aged 21-40 years with blue collar jobs. Major reasons for dropouts are retracted consent and medical unsuitability. Donors have improved socioeconomic status. In this study, 53% complied with expected medical follow-up, showing mean serum creatinine within normal range. Proteinuria appeared in 2 of 79 donors. This regulated approach provides a rational, accessible, and equitable donor allocation program. It safeguards the rights of donors and avoids donor exploitation and proliferation of unregulated organ sale. Data collection on their postoperative renal function will show long-term outcome of kidney donation from live donors.

Testing attitudes and opinions ofgraduate students in Osijek towards organ donation and transplantation. Examinees and methods: The research included 99 students of math gymnasium in Osijek (54 males and 45 females, mean age 18 years). They fulfilled an anonymous questionnaire, consisted of 24 questions about transplantation, willingness to donate organs, consciousness of importance of donating organs and attitudes of religion towards organ donation. Statistical analysis was made by SPSS 16.0 computer program using Chi-square test. Most of the gymnasium students (80.8%) have already heard about organ donation, 76.8% of them have received information by television. 59.4% students know how a transplantation is being performed, but the majority (64.6%) of them don't know whom to address to receive additional information about organ donation. 27.3% students have discussed transplantation inside their families and 17.2% examinees know someone who signed the donor card. 55.6% examinees are convinced that transplantation procedure is safe and efficient. 41.4% thinks that family should give permission for explantation of a deceased patient's organs, while 33.3% consider it not necessary. Regarding the question whether examinees think that organ transplantation was a mutilation, 91.9% of them answered "no". Although 55.6% students believe that doctors would put the same effort in saving patients, independent whether they possessed donor card or not, there were 60.6% that thought it was possible to obtain organ in Croatia by illegal ways. Nevertheless, 79.8% students would receive organ from a deceased person, 64.6% would donate organs after their death. Observing ethical and religious attitudes, 92.9% are sure that organ donation is a humane gesture. 82.8% examinees were believers and 60.6% of them didn't know attitudes of their religion towards organ donation. Women have significantly more willingness to donate their organ to family member during their lives (97.8%), while 81.5% males would do the same, p=0.035. Lower percentage of atheists were found among women (6.7%) than in men (25.9%), p=0.011. 53.7% males consider their religion to be against organ donation, while only 17.8% females, p=0.046. High school graduates have mostly heard about organ transplantation (many of them by television) and the majority has positive attitude and are willing to donate theirs and to receive organs from another person. Such willingness and tendency towards organ donation should be taken with reserve, because it was relatively young population, without life experience in similar situations. Within their population, believers are predominating, and they often don't know whether their religion is pro organ donation or against it. Smaller proportion, but still the majority of the examinees, considers the transplantation to be a safe procedure. Women and men show differences regarding information, attitudes and willingness to make a sacrifice. Women are more willing to donate organs to a family member. Still, there is not enough discussion about transplantation inside each family. Rate of ignorance and lack of information about transplantation and organ donation, indicates a need for better representation of this topic in media, schools, religious institutions and inside family.
Bone and muscle atrophy with suspension of the rat

In order to identify a suitable model for the study of muscle atrophy due to suspension in space, a modified version of the Morey tail suspension model was used to measure the atrophic responses of rat bone and muscle to 14-30 days of unloading of the hindlimbs. The progress of atrophy was measured by increases in methylene diphosphonate (MDP) uptake. It is found that bone uptake of methylene diphosphonate followed a phasic pattern similar to changes in the bone formation rate of immobilized dogs and cats. Increased MDP uptake after a period of 60 days indicated an accelerated bone metabolism. Maximum muscle atrophy in the suspended rats was distinctly different from immobilization atrophy. On the basis of the experimental results, it is concluded that the tail suspension model is an adequate simulation of bone atrophy due to suspension.

As the restaurant delivery robot is often in a dynamic and complex environment, including the chairs inadvertently moved to the channel and customers coming and going. The traditional Markov decision process path planning algorithm is not save, the robot is very close to the table and chairs. To solve this problem, this paper proposes the Markov Decision Process with a penalty term called MDPPT path planning algorithm according to the traditional Markov decision process (MDP). For MDP, if the restaurant delivery robot bumps into an obstacle, the reward it receives is part of the current status reward. For the MDPPT, the reward it receives not only the part of the current status but also a negative constant term. Simulation results show that the MDPPT algorithm can plan a more secure path.

The recent discovery of bacterial receptors such as NOD2 that contribute to crosstalk between innate and adaptive immune systems in the digestive tract constitutes an important challenge in our understanding of liver injury mechanisms. The present study focuses on NOD2 functions during liver injury. NOD2, TNF-alpha and IFN-gamma mRNA were quantified using real-time PCR in liver samples from patients and mice with liver injury. We evaluated the susceptibility of concanavalin A (ConA) challenge in NOD2-deficient mice (Nod2-/-) compared to wild-type littermates. We tested the effect of muramyl dipeptide (MDP), the specific activator of NOD2, on ConA-induced liver injury in C57BL/6 mice. We studied the cellular distribution and the role of NOD2 in immune cells and hepatocytes. We demonstrated that NOD2, TNF-alpha and IFN-gamma were upregulated during liver injury in mice and humans. Nod2-/- mice were resistant to ConA-induced hepatitis compared to their wild-type littermates, through reduced IFN-gamma production by immune cells. Conversely, administration of MDP exacerbated ConA-induced liver injury. MDP was a strong inducer of IFN-gamma in freshly isolated human PBMC, splenocytes and hepatocytes. Our study supports the hypothesis that NOD2 contributes to liver injury via a regulatory mechanism affecting immune cells infiltrating the liver and hepatocytes. Taken together, our results indicate that NOD2 may represent a new therapeutic target in liver diseases.

Grape variety [Cabernet Sauvignon (CS) and Merlot (M)] effect on the proanthocyanidin composition and sensory perception of wine grapes from Bordeaux vineyards for two successive vintages (2006 and 2007) is reported. The flavan-3-ol monomers [(+)-catechin = C, (-)-epicatechin = EC, (-)-epicatechin-O-gallatte = ECG] and the proanthocyanidin oligomers [dimers B1, B2, B3, and B4 and trimer Cat-Cat-Epi (T)] in grape seed and skin tannin extracts were identified and quantified at harvest. Proanthocyanidin subunit compositions, percentage of galloylation (%G), and percentage of prodelphinidins (%P) as well as mean degree of polymerization (mDP) of the proanthocyanidin fraction were determined. Sensory analysis concerning the astringency and bitterness intensity of the proanthocyanidins of skin and seed tannin extracts was also performed. The results showed that proanthocyanidin composition can be greatly affected by grape variety. For both vintages between CS and M, significant differences were found on mDP (p < 0.05) in seed tannin extracts, whereas in skin tannin extracts, significant differences were observed for %G and %P (p < 0.05). Sensory analysis showed that grape variety influenced neither astringency nor bitterness intensity perception for both skin and seed tannin extracts for the two successive vintages studied. A positive correlation was found between astringency intensity, mDP, and B3 content in skin tannin extracts.

The direct and simultaneous quantitative determination of the mean degree of polymerization (mDP) and the degree of galloylation (%G) in grape seeds were quantified using diffuse reflectance infrared Fourier transform spectroscopy and partial least squares (PLS). The results were compared with those obtained using the conventional analysis employing phloroglucinolysis as pretreatment followed by high performance liquid chromatography-UV and mass spectrometry detection. Infrared spectra were recorded in solid state samples after freeze drying. The 2nd derivative of the 1832 to 1416 and 918 to 739 cm(-1) spectral regions for the quantification of mDP, the 2nd derivative of the 1813 to 607 cm(-1) spectral region for the degree of %G determination and PLS regression were used. The determination coefficients (R(2) ) of mDP and %G were 0.99 and 0.98, respectively. The corresponding values of the root-mean-square error of calibration were found 0.506 and 0.692, the root-mean-square error of cross validation 0.811 and 0.921, and the root-mean-square error of prediction 0.612 and 0.801. The proposed method in comparison with the conventional method is simpler, less time consuming, more economical, and requires reduced quantities of chemical reagents and fewer sample pretreatment steps. It could be a starting point for the design of more specific models according to the requirements of the wineries. © 2015 Institute of Food Technologists®

The traditional concept of barter exchange in economics has been extended in the modern era to the area of living-donor kidney transplantation, where one incompatible donor-candidate pair is matched to another pair with a complementary incompatibility, such that the donor from one pair gives an organ to a compatible candidate in the other pair and vice versa. Kidney paired donation (KPD) programs provide a unique and important platform for living incompatible donor-candidate pairs to exchange organs in order to achieve mutual benefit. In this paper, we propose novel organ allocation strategies to arrange kidney exchanges under uncertainties with advantages, including (i) allowance for a general utility-based evaluation of potential kidney transplants and an explicit consideration of stochastic features inherent in a KPD program; and (ii) exploitation of possible alternative exchanges when the originally planned allocation cannot be fully executed. This allocation strategy is implemented using an integer programming (IP) formulation, and its implication is assessed via a data-based simulation system by tracking an evolving KPD program over a series of match runs. Extensive simulation studies are provided to illustrate our proposed approach.

In 1998 in the Centro de Investigaciones Medico Quirurgicas the Transplant Coordination Office (TCO) was created, with the aim to organize a system to support a hepatic transplantation program. This organization, which changed the transplantation-donation process not only in our center but in the whole country, is described in this article. The files of donors generated in our hospital were studied together with the transplant coordination records, from 1999 till the first half of 2002. In the period studied, 21 potential donors were diagnosed with brain death, yielding a donation rate of 71.4%. Brain death was most frequently caused by vascular brain disease; however, in the realized donor group, the cranioencephalic trauma predominated. The typical donor was a man of average age 39.2 years (range, 18-86 years). Among the potential donors, 24% were excluded based on medical criteria, and 5% due to family objections. Forty liver transplantation were performed in 36 patients including 1 liver-kidney simultaneous procedure. The principal etiologies for transplant included hepatitis C virus cirrhosis, 22%; alcoholic, 19%; and acute hepatic failure, 13%. Kidney transplantations were performed in 70 patients, including 41 from cadaveric donors (53.6%) and 29 from living related donors (41.4%). In 2001, a pancreas-kidney transplantation program was started. The creation of the TCO has been of paramount importance to optimize transplantation program functions.

Neonatal liver cell donation: a case report.
Godfrey, Kathleen; Kish, Mary Z
2014-01-01
Traditional organ transplant options for newborns have been rare. There continues to be an increasing need for organs for transplant and a limited number of available organs, especially for small children. Liver cell transplantation is a promising alternative to orthotopic liver transplantation to treat liver-based inborn errors of metabolism.1 The procedure is minimally invasive and can be performed repeatedly. The safety of the procedure has been well established, and the clinical results are encouraging.1 The liver cell donation process is an option for families who experience the loss of a newborn and offers them a legacy for their child by providing life for others. The purpose of this article is to discuss the neonatal liver cell donation process and present a case report of an anencephalic infant whose parents chose to participate in this unique program.
Safe and ethical living kidney donation in Qatar: A national health system's approach.
Asim, Muhammad; Al-Maslamani, Yousuf; Al-Malki, Hassan
2017-01-01
The increasing incidence of end-stage kidney disease in Qatar has led to growing demand for donor kidneys. The deceased donor kidney program has yet to achieve its full potential; hence, living kidney donation has been widely adopted as an appropriate alternative. The reliance on living kidney donors however, raises a number of social, ethical, and legal concerns surrounding informed consent, voluntarism, psychosocial evaluation, perioperative care, and long-term follow-up of living kidney donors. Many of these concerns become heightened in a multicultural, multilingual society within a Gulf country such as Qatar. This article provides an insight into the challenges that living kidney donation poses in a multiethnic society with significant socioeconomic divides. It also discusses the remedial measures that the Qatari government, healthcare authorities, and transplant community have adopted to address these issues.

The three major research domains of REDS/REDS-II have been infectious disease risk evaluation, blood donation availability, and blood donor characterization. Both programs have made significant contributions to transfusion medicine research methodology by the use of mathematical modeling, large-scale donor surveys, innovative methods of repository sample storage, and establishing an infrastructure that responded to potential emerging blood safety threats such as XMRV. Blood safety studies have included protocols evaluating epidemiologic and/or laboratory aspects of HIV, HTLV I/II, HCV, HBV, WNV, CMV, HHV-8, B19V, malaria, CJD, influenza, and T. cruzi infections. Other analyses have characterized: blood donor demographics, motivations to donate, factors influencing donor return, behavioral risk factors, donors’ perception of the blood donation screening process, and aspects of donor deferral. In REDS-II, two large-scale blood donor protocols examined iron deficiency in donors and the prevalence of leukocyte antibodies. This review describes the major study results from over 150 peer-reviewed articles published by these two REDS programs. In 2011, a new seven year program, the Recipient Epidemiology and Donor Evaluation Study-III (REDS-III), was launched. REDS-III expands beyond donor-based research to include studies of blood transfusion recipients in the hospital setting, and adds a third country, South Africa, to the international program.

Background The Recipient Epidemiology and Donor Evaluation Study -III (REDS-III) is a 7-year multicenter transfusion safety research initiative launched in 2011 by the National Heart, Lung, and Blood Institute. Study design The domestic component involves 4 blood centers, 12 hospitals, a data coordinating center, and a central laboratory. The international component consists of distinct programs in Brazil, China, and South Africa which involve US and in-country investigators. Results REDS-III is using two major methods to address key research priorities in blood banking/transfusion medicine. First, there will be numerous analyses of large “core” databases; the international programs have each constructed a donor/donation database while the domestic program has established a detailed research database that links data from blood donors and their donations, the components made from these donations, and data extracts from the electronic medical records of the recipients of these components. Secondly, there are more than 25 focused research protocols involving transfusion recipients, blood donors, or both that are either in progress or scheduled to begin within the next 3 years. Areas of study include transfusion epidemiology and blood utilization; transfusion outcomes; non-infectious transfusion risks; HIV-related safety issues (particularly in the international programs); emerging infectious agents; blood component quality; donor health and safety; and other donor issues. Conclusions It is intended that REDS-III serve as an impetus for more widespread recipient and linked donor-recipient research in the US as well as to help assure a safe and available blood supply in the US and in international locations.

Regular physical activity (PA) enhances weight-loss and reduces risk of chronic disease. However, as few as 10% of U.S. adults engage in regular PA. Incentive programs to promote PA have shown some promise, but have typically used incentives that are too large to sustain over time and have not demonstrated habit formation or been tested in community settings. This report presents the rationale and design of a randomized pilot study testing the feasibility and preliminary efficacy of small monetary incentives for PA (n=25) versus charitable donations in the same amount (n=25) versus control (n=25) over 12months among 75 low-active but otherwise healthy adults at a local YMCA. Incentives are based on YMCA attendance, which is verified by electronic swipe card data and is the primary study outcome, with self-reported minutes/week of PA assessed as a secondary outcome. Incentives are intentionally small enough-$1/session, maximum of $5/week-such that they could be indefinitely sustained by community organizations, privately-owned health clubs, healthcare organizations, or employers (e.g., employer fitness facilities). Costs of the incentive program for the sponsoring organization may be partially offset by increases in membership resulting from the appeal of the program. Moreover, if efficacious, the charitable donation incentive program may have the added benefit of building social capital for the sponsoring organization and potentially serving as a tax write-off, thus further offsetting the cost of the incentives. Findings will also have implications for the use of financially sustainable community-based incentive programs for other health-related behaviors (e.g., weight loss, smoking).

Despite the national advocacy campaign for kidney transplantation from deceased donors in the Philippines 96% of kidneys transplanted into 721 kidney transplants from 1999 to 2001 came from living donors. A national survey on the knowledge, attitudes and perceptions of Filipinos on organ donation in 2001 showed factors that disadvantaged deceased organ donation to be poor understanding of "brain death," religion, and fear of the operation. These concerns were addressed and another survey was conducted in 2005. To compare knowledge, attitudes, and perceptions of Filipinos on organ donation between 2001 and 2005, and compare the number of kidney transplants from deceased donors between 2001 until 2008. Two surveys in 15 regions of the Philippines were conducted using multistage sampling. Using a structured questionnaire there were 2000 respondents in 2001, and 2140 in 2005. Analysis was performed using chi-square analysis. The majority of respondents knew about kidney donation. Between 2001 and 2005, there was increased awareness that transplants came from both living and deceased donors (37% to 41%) and a decline in those believing transplants came only from deceased donors (14% to 9%). Willingness to become a living (59% to 87%) or a deceased donor (35% to 49%) increased. The increase in transplantation from deceased donors from an average of 10 per year from 1999 to 2001 to 31 per year from 2006 to 2008. Increased awareness about kidney donation among Filipinos, improved consent to become an organ donor, and an increase in kidney transplantation from deceased donors occurred from 2001 to 2008.

Despite the lifesaving benefits of organ and tissue donation, a worldwide shortage of suitable and registered donors exists. Although the reasons for this shortage are multifactorial, it has been recognized that distinct barriers to registration, family discussion, and consent that require targeted intervention and action are present among minority cultural, religious, and immigrant communities. To explore the knowledge, attitudes, and beliefs of 3 orthodox religious communities in Australia (Macedonian, Greek, and Serbian Orthodox) and determine the implications for engaging with these communities to improve knowledge, attitudes, family discussion, and the ability to make an informed decision about donation. Qualitative approach using focus groups moderated by researchers and bicultural health workers with the assistance of accredited interpreters. 98 adult members of the Greek, Macedonian, and Serbian Orthodox communities in the Illawarra region of New South Wales, Australia. Clear barriers to discussing and making an informed decision about organ and tissue donation were identified. Knowledge of processes and procedures was low and discussion about death (and organ and tissue donation) with family members and loved ones was considered taboo. Despite these barriers, all 3 communities expressed a desire for more information and engagement. Of particular interest were the perspectives of 3 types of "experts": medical, religious, and other community members (who had experience with the organ and tissue donation system). Future programs designed for orthodox religious communities should consider the need for active strategies that facilitate information sharing and engagement between community members and these 3 types of experts.
