    Chou, Shin-Shang; Yan, Hsiu-Fang; Huang, Hsiu-Ya; Tseng, Kuan-Jui; Kuo, Shu-Chen

    2012-01-01

    This study intended to use a human-centered design study method to develop a bar-code technology in blood sampling process. By using the multilevel analysis to gather the information, the bar-code technology has been constructed to identify the patient's identification, simplify the work process, and prevent medical error rates. A Technology Acceptance Model questionnaire was developed to assess the effectiveness of system and the data of patient's identification and sample errors were collected daily. The average scores of 8 items users' perceived ease of use was 25.21(3.72), 9 items users' perceived usefulness was 28.53(5.00), and 14 items task-technology fit was 52.24(7.09), the rate of patient identification error and samples with order cancelled were down to zero, however, new errors were generated after the new system deployed; which were the position of barcode stickers on the sample tubes. Overall, more than half of nurses (62.5%) were willing to use the new system.

  15. Establishment of Small Wind Regional Test Centers

    SciTech Connect

    Jimenez, T.; Forsyth, T.; Huskey, A.; Mendoza, I.; Sinclair, K.; Smith, J.

    2011-01-01

    The rapid growth of the small wind turbine (SWT) market is attracting numerous entrants. Small wind turbine purchasers now have many options, but often lack information (such as third-party certification) to select a quality turbine. Most SWTs do not have third-party certification due to the expense and difficulty of the certification process. Until recently, the only SWT certification bodies were in Europe. In North America, testing has been limited to a small number of U.S. Department of Energy (DOE) subsidized tests conducted at the National Renewable Energy Laboratory's (NREL) National Wind Technology Center (NWTC) under the ongoing Independent Testing Project. During the past few years, DOE, the National Renewable Energy Laboratory (NREL), and some states have worked with the North American SWT industry to create a SWT certification infrastructure. The goal is to increase the number of certified turbines and gain greater consumer confidence in SWT technology. The American Wind Energy Association (AWEA) released the AWEA Small Wind Turbine Performance and Safety Standard, AWEA Standard 9.1 - 2009, in December 2009. The Small Wind Certification Council (SWCC) and Intertek, North American SWT certification bodies, began accepting applications for certification to the AWEA standard in 2010. To reduce certification testing costs, DOE and NREL are providing financial and technical assistance for an initial round of tests at four SWT test sites, which were selected through a competitive solicitation. The four organizations selected are Windward Engineering (Utah), The Alternative Energy Institute at West Texas A and M (Texas), a consortium consisting of Kansas State University and Colby Community College (Kansas), and Intertek (New York). Each organization will test two small wind turbines as part of their respective subcontracts with DOE and NREL. The testing results will be made publically available. The goal is to establish a lower-cost U.S. small wind testing

  16. Establishing cost centers within libraries of medical centers.

    PubMed Central

    Schultz, C K

    1983-01-01

    Medical centers that educate students, treat patients, and perform medical research usually adopt accounting methods for separating those functions financially--designating each function as a cost center. Faculty members who participate in more than one of the separately charged activities have their salaries apportioned accordingly. Cost-shared services, such as a computer facility or a power plant, may also be apportioned among the cost centers. Given this approach to accounting, the shared services of the medical center's library should be included in such an apportionment. Whether such is the case, why the matter is of concern, and how such accounting can be performed were recently studied. PMID:6860398

    Oral Diseases (2010) 16, 586-591 High quality clinical research is necessary to improve oral health and translate research findings to the practice of dentistry. This has led many academic institutions to consider establishing a formal clinical research center. This is not a trivial undertaking and requires that the center have an appropriate physical infrastructure, trained investigators with recognized expertise in the planning and conduct of high quality clinical research, and very importantly, a financial plan to assure its long-term sustainability. The purpose of this paper is to provide some guidance and practical advice with respect to factors that should be considered in developing and maintaining a successful oral disease clinical research center. © 2010 John Wiley & Sons A/S.

    Blood is donated either as whole blood, with subsequent component processing, or through the use of apheresis devices that extract one or more components and return the rest of the donation to the donor. Blood component therapy supplanted whole blood transfusion in industrialized countries in the middle of the twentieth century and remains the standard of care for the majority of patients receiving a transfusion. Traditionally, blood has been processed into three main blood products: red blood cell concentrates; platelet concentrates; and transfusable plasma. Ensuring that these products are of high quality and that they deliver their intended benefits to patients throughout their shelf-life is a complex task. Further complexity has been added with the development of products stored under nonstandard conditions or subjected to additional manufacturing steps (e.g., cryopreserved platelets, irradiated red cells, and lyophilized plasma). Here we review established and emerging methodologies for assessing blood product quality and address controversies and uncertainties in this thriving and active field of investigation.

    Creating a surgical specialty referral center requires a strong interest, expertise, and a market demand in that particular field, as well as some form of promotion. In 2004, we established a tertiary hernia referral center. Our goal in this study was to examine its impact on institutional volume and economics. The database of all hernia repairs (2004-2011) was reviewed comparing hernia repair type and volume and center financial performance. The ventral hernia repair (VHR) patient subset was further analyzed with particular attention paid to previous repairs, comorbidities, referral patterns, and the concomitant involvement of plastic surgery. From 2004 to 2011, 4927 hernia repairs were performed: 39.3% inguinal, 35.5% ventral or incisional, 16.2% umbilical, 5.8% diaphragmatic, 1.6% femoral, and 1.5% other. Annual billing increased yearly from 7% to 85% and averaged 37% per year. Comparing 2004 with 2011, procedural volume increased 234%, and billing increased 713%. During that period, there was a 2.5-fold increase in open VHRs, and plastic surgeon involvement increased almost 8-fold, (P = .004). In 2005, 51 VHR patients had a previous repair, 27.0% with mesh, versus 114 previous VHR in 2011, 58.3% with mesh (P < .0001). For VHR, in-state referrals from 2004 to 2011 increased 340% while out-of-state referrals jumped 580%. In 2011, 21% of all patients had more than 4 comorbidities, significantly increased from 2004 (P = .02). The establishment of a tertiary, regional referral center for hernia repair has led to a substantial increase in surgical volume, complexity, referral geography, and financial benefit to the institution. © The Author(s) 2014.

    2001-01-01

    With the objective of establishing the Special Bureau for the Oceans (SBO), a new archival center for ocean angular momentum (OAM) products, we have computed and analyzed a number of OAM products from several ocean models, with and without data assimilation. All three components of OAM (axial term related to length of day variations and equatorial terms related to polar motion) have been examined in detail, in comparison to the respective Earth rotation parameters. An 11+ year time series of OAM given at 5-day intervals has been made publicly available. Other OAM products spanning longer periods and with higher temporal resolution, as well as products calculated from ocean model/data assimilation systems, have been prepared and should become part of the SBO archives in the near future.

    2012-01-01

    Ovine animal models are widely used to conduct preclinical studies, e.g., to evaluate cardiovascular prostheses intended to be applied in man. However, although analyzed in many of those studies, information about ovine blood reference values is scanty. The aim of this study is to establish a reference list of ovine blood parameters relevant for blood coagulation. A cohort of 47 mature ewes was evaluated. Parameters comprised the following: cells and cellular components-platelet, red, and white cell counts (including subsets), hemoglobin (Hb), hematocrit (HCT), mean corpuscular hemoglobin (MCH) and mean corpuscular volume (MCV), and MCH concentration (MCHC); global tests of coagulation-prothrombin time (Quick's time) and activated partial thromboplastin time (aPTT); and parameters relevant for blood coagulation-fibrinogen, antithrombin (AT), and von Willebrand Factor. After explorative data analysis, a list of ovine reference values was established. Interestingly, a comparison with human reference values revealed some interspecies differences between sheep and man, i.e., much higher ovine ranges for some cell counts (neutrophils, lymphocytes, basophils, eosinophils, and platelets) but lower values for some other parameters (Hb, HCT, MCV, MCH, AT, and Quick's test). We established a reference list of ovine blood count and blood coagulation parameters. Because of some peculiarities of the ovine blood, this list may have implications for the interpretation of experimental data.

    It is considered that establishing accredited specialized centers can serve as a marketing tool. This study investigated whether accredited specialized centers influence patients' choice of hospital. A total of 2,389 patients was included in a questionnaire survey: 468 at the Department of Gynecology, 745 at the certified University Breast Center of Franconia, 1,000 at the University Perinatal Center of Franconia and 176 for whom classification details were lacking. Among the oncological patients, physicians in private practice played an important role in the choice of hospital (58.4 vs. 25.7%; P < 0.001; OR 4.058). Among obstetric patients, the primary factors were recommendations from family [odds ratio (OR) 0.495], friends (OR 0.218), and previous personal experience of the hospital (OR 0.695). For oncological patients, treatment quality (OR 2.693), availability of a center (OR 1.785), and certification (OR 3.939) were comparatively more important. For obstetric patients, friendliness (OR 0.409) and attractive accommodation (OR 0.153) were more important. Physicians are the most important source of recommendations for oncological patients. From the marketing point of view, intensive involvement of local private-practice physicians is necessary. The availability of certified perinatal centers does not currently play any part in patients' choice of hospital.

  4. Establishing a Geriatric Psychiatric Consultation in a VA Medical Center.

    1995-01-01

    The authors describe the establishment of a Geriatric Psychiatry Consultation-Liaison Team (GPCLT) at a Veterans Administration Medical Center (VAMC) that previously had no organized geriatric psychiatric service. Geriatric psychiatric consultation was required by three intermediate-care units treating older, chronically medically ill veterans with psychiatric symptoms or disorders. The GPCLT comprised a black, female geriatric psychiatrist and a white, male social worker. This combination of disciplines maximized skills, and the ethnic-gender differences of team members addressed questions of racial tension and gender issues between patients and VAMC staff members. The compliance with recommendations of the GPCLT, ranging from 89% to 98% across the three units, its selection as a clinical site for a university-affiliated Geriatric Psychiatry Fellowship Program, and the increase in the total hours of social work time assigned to the GPCLT documented the positive perception of the team by both the VAMC and the affiliated university. Specific recommendations are presented for consideration by other, similar settings. Copyright © 1995 American Association for Geriatric Psychiatry. Published by Elsevier Inc. All rights reserved.

    Reports from studies conducted in several countries indicate a high incidence of bacterial contamination of donor blood. The prevalence of bacterial contamination of blood and its products in Ghana is not known. This study was conducted to determine the prevalence of bacterial contamination of blood and its products at the three major blood transfusion centers in the Greater Accra Region of Ghana. Stored whole blood and its products were cultured on different media, and isolates were identified using standard biochemical and bacteriological methods. The susceptibility of the isolates to selected antimicrobial agents was also determined by the disc diffusion method. The overall prevalence rate was 9% (28/303; whole blood, 13% [24/192]; plasma, 3% [2/79]; platelet, 9% [2/22]). The Gram-positive bacteria isolated were coagulase-negative Staphylococcus, S. aureus, and Bacillus spp., and the Gram-negative organisms were Yersinia enterocolitica, Citrobacter freundii, Escherichia coli, Pseudomonas aeruginosa, and Klebsiella pneumoniae. The Gram-positive bacteria were sensitive to cloxacillin, erythromycin, tetracycline, and gentamicin but resistant to penicillin, ampicillin, cefuroxime, and cotrimoxazole, while the Gram-negative bacteria were sensitive to amikacin and gentamicin but resistant to chloramphenicol, tetracycline, ampicillin, cefuroxime, cefotaxime (except Y. enterocolitica), and cotrimoxazole. Our results suggest that bacterial contamination of blood and its products is prevalent in Ghana.

  6. Transfusion safety: is this the business of blood centers?

    ATSO is in a unique position to break down organizational silos between hospitals and blood centers through the development of a collaborative relationship between the two entities. Use of the TSO as blood center staff centralizes the role into a consultative position thereby retaining the independence of the hospitals. The TSO position then becomes a value-added service offered by the blood center designed to supplement processes within the hospital.Whether the TSO is based in the hospital or the blood center, improvements are gained through appropriate utilization of blood components, reductions in hospital costs, ongoing education of hospital staff involved in transfusion practice, and increased availability of blood products within the community. Implementation and standardization of best practice processes for ordering and administration of blood products developed by TSOs leads to improved patient outcomes. As a liaison between hospitals and blood centers, the TSO integrates the mutual goal of transfusion safety: the provision of the safest blood product to the right patient at the right time for the right reason.

  1. Establishment of Small Wind Regional Test Centers: Preprint

    Jimenez, T.; Forsyth, T.; Huskey, A.; Mendoza, I.; Sinclair, K.; Smith, J.

    2011-03-01

    The rapid growth of the small wind turbine (SWT) market is attracting numerous entrants. Small wind turbine purchasers now have many options but often lack information (such as third-party certification) to select a quality turbine. Most SWTs do not have third-party certification due to the expense and difficulty of the certification process. Until recently, the only SWT certification bodies were in Europe. In North America, testing has been limited to a small number of U.S. Department of Energy (DOE) subsidized tests conducted at the National Wind Technology Center (NWTC) under the ongoing Independent Testing Project. Within the past few years, the DOE, National Renewable Energy Lab (NREL), and some states have worked with the North American SWT industry to create a SWT certification infrastructure. The goal is to increase the number of certified turbines and gain greater consumer confidence in SWT technology. The American Wind Energy Association (AWEA) released the AWEA Small Wind Turbine Performance and Safety Standard (AWEA Standard 9.1 - 2009) in December 2009. The Small Wind Certification Council (SWCC), a North American certification body, began accepting applications for certification to the AWEA standard in February 2010. To reduce certification testing costs, DOE/NREL is providing financial and technical assistance for an initial round of tests at four SWT test sites which were selected via a competitive solicitation. The four organizations selected are Windward Engineering (Utah), The Alternative Energy Institute at West Texas A&M (Texas), a consortium consisting of Kansas State University and Colby Community College (Kansas), and Intertek (New York). Each organization will test two small wind turbines as part of their respective subcontract with DOE/NREL. The testing results will be made publically available. The goal is to establish a lower-cost U.S. small wind testing capability that will lead to increased SWT certification.

    Access to blood components is required for healthcare establishments, particularly for emergency situation and hospital blood bank was often a response to this requirement. However, the complexity of regulation and economic pressures lead healthcare establishment to review regularly their need for a blood bank. This assessment requires analysis of need for transfusions in terms of delay, quantity and clinical situations to which they must respond. When a blood bank is required, three kinds could be under consideration: emergency blood bank, intermediate blood bank and issuance blood bank. According to requirements, advantages and disadvantages of each kind, healthcare establishments would select the most suitable one.

    1998-10-01

    The success of the center, in fact its very existence, is the result of cooperation among many persons and agencies. Financial gifts, loans and grants have given the clinic a three-year time period to learn valuable lessons on how to organize for self-sufficiency. Staff have learned how to market to increase patient visit and have obtained Federal Rural Health Clinic status which will increase revenues substantially. Nurse Practitioners are learning appropriate visit coding and hold regular brainstorming meetings to develop creative business opportunities to assure financial stability. As a result of these experiences, the NP faculty have been able to design learning experiences for the nurse practitioner students which introduce them to entrepreneurial realities. Challenges are being met by the NPs in this rural practice which require vigor, creativity, and vigilance. Once the center reaches the level of self-sufficiency, it is the intent of the community to build a facility which can support a significant increase in patient load and still have room for other social and health services to operate within the facility. Bridges to the medical community are being strengthened through better communication and more community involvement. Educating the public and the medical community about the role of nurse practitioners and the broad base of nursing centers is a continual challenge for both faculty and students at the School of Nursing.

    The allogenic transplantation of hemopoietic stem cell from bone marrow and peripheral blood is limited due to the necessity to identify HLA matched donor within the family or in bone marrow donor registries. Although, more than 10 million donors are available worldwide, completely HLA matched donors could be found only for 75% of the patients. It is well known that transplantations of hematopoietic stem cell from cord blood are characterized with a lower risk of GvHD and therefore do not require so strict criteria for HLA matching, and less time for search of matched donor is needed. The necessity to establish a National cord blood bank in Bulgaria is emphasized further by the heterogeneity of HLA allele and haplotype distribution in the Bulgarian population. That could be explained by the ethnic diversity of the population. As a result some alleles are more frequent in Bulgarians compared to other populations. The organization, accreditation, and development of a strategy for a National cord blood bank will be discussed.

    Over 250 medical centers worldwide offer ketogenic diets to children with epilepsy; however, access to these therapies has been extremely limited for adults until recent years. We examine our 5-year experience creating and implementing a dedicated Adult Epilepsy Diet Center designed to provide adults with epilepsy access to ketogenic diets. Outpatients seen at the Johns Hopkins Adult Epilepsy Diet Center from August 2010 thru September 2015 age 18years and older were enrolled in a prospective open-label observational study. Patients that also enrolled in ongoing clinical diet trials were excluded from this study. Participant demographics, diet type, urine and/or serum ketones, laboratory studies, seizure frequency, diet duration, reason for discontinuing diet therapy, and side effects were recorded. A subgroup analysis of participants that met International League Against Epilepsy (ILAE) criteria for drug-resistant epilepsy (DRE) and were treated de novo with a Modified Atkins Diet (MAD) was performed to compare outcomes with the current literature regarding efficacy of other antiseizure treatments for DRE. Two hundred and twenty-nine adults attended the Adult Epilepsy Diet Center, and 168 met inclusion criteria. Two-thirds (n=113, 67%) were women with an age range of 18-86years at the initial visit. Thirty-five participants (21%, n=133) were already on a therapeutic diet while 79% (n=133) were naïve to diet therapy at the time of the initial visit. Diet-naïve participants were typically prescribed MAD (n=130, 98%), unless unable to intake adequate oral nutrition, in which case they were prescribed KD (n=1) or a combination of oral MAD and ketogenic formula (n=2). Twenty-nine of 130 (22%) participants prescribed MAD elected not to start or were lost to follow-up, and 101 (78%) began MAD. A subgroup analysis was performed on one hundred and six participants naïve to diet therapy that met International League Against Epilepsy criteria for DRE, were able to

    Diffuse correlation spectroscopy (DCS) measurements of blood flow rely on the sensitivity of the temporal autocorrelation function of diffusively scattered light to red blood cell (RBC) mean square displacement (MSD). For RBCs flowing with convective velocity [Formula: see text], the autocorrelation is expected to decay exponentially with [Formula: see text], where [Formula: see text] is the delay time. RBCs also experience shear-induced diffusion with a diffusion coefficient [Formula: see text] and an MSD of [Formula: see text]. Surprisingly, experimental data primarily reflect diffusive behavior. To provide quantitative estimates of the relative contributions of convective and diffusive movements, we performed Monte Carlo simulations of light scattering through tissue of varying vessel densities. We assumed laminar vessel flow profiles and accounted for shear-induced diffusion effects. In agreement with experimental data, we found that diffusive motion dominates the correlation decay for typical DCS measurement parameters. Furthermore, our model offers a quantitative relationship between the RBC diffusion coefficient and absolute tissue blood flow. We thus offer, for the first time, theoretical support for the empirically accepted ability of the DCS blood flow index ([Formula: see text]) to quantify tissue perfusion. We find [Formula: see text] to be linearly proportional to blood flow, but with a proportionality modulated by the hemoglobin concentration and the average blood vessel diameter.

    Access to existing travel data is critical for many analysis efforts that lack the time or resources to support detailed data collection. High-resolution data sets provide particular value, but also present a challenge for preserving the anonymity of the original survey participants. To address this dilemma of providing data access while preserving privacy, the National Renewable Energy Laboratory and the U.S. Department of Transportation have launched the Transportation Secure Data Center (TSDC). TSDC data sets include those from regional travel surveys and studies that increasingly use global positioning system devices. Data provided by different collecting agencies varies with respect to formatting, elements included and level of processing conducted in support of the original purpose. The TSDC relies on a number of geospatial and other analysis tools to ensure data quality and to generate useful information outputs. TSDC users can access the processed data in two different ways. The first is by downloading summary results and second-by-second vehicle speed profiles (with latitude/longitude information removed) from a publicly-accessible website. The second method involves applying for a remote connection account to a controlled-access environment where spatial analysis can be conducted, but raw data cannot be removed.

    Develop a trans-disciplinary repository of genomics education resources using a Web-based learning management system. The repository maps and organizes genetic-genomic information and materials relevant to educators by healthcare discipline-specific competencies and performance indicators. An interdisciplinary project team was established to guide toolkit repository building and usability testing. The toolkit was built using the X-CREDIT software on the Moodle learning management platform, which includes a mapping matrix and browsing function that captures teaching resources in a searchable database linked to competencies, knowledge areas, performance indicators, learning activities and resources, and outcome assessments. Discipline-specific advisory groups assisted in resource identification, competency mapping, and peer review. The toolkit is multidisciplinary, currently including physician assistants and nurses, and provides a resource crosslink to discipline-specific competencies. All resources have a detailed description, and users may contribute new resources, which are peer reviewed for relevance and accuracy by an editorial board. Alpha and beta testing using online usability surveys that included toolkit exercises helped refine the structure, look, and navigation of the final website. One hundred thirty faculty-124 nursing and 6 physician assistant faculty-agreed to participate. Of those, 59 users (45.4% response rate) completed the online usability survey. Nearly all users (94.9%) were able to find a competency that was relevant to their topic, and 85.4% were able to locate the relevant performance indicators. The majority (86.5%) felt the model adequately described the relationships between competencies, performance indicators, learning activities-resources, and assessments, and made conceptual sense.

    Structural and functional brain connectivity, synaptic activity and information processing require highly coordinated signal transduction between different cell types within the neurovascular unit and intact blood-brain barrier (BBB) functions. Here, we examine the mechanisms regulating the formation and maintenance of the BBB and functions of BBB-associated cell types. Furthermore, we discuss the growing evidence associating BBB breakdown with the pathogenesis of inherited monogenic neurological disorders and complex multifactorial diseases including Alzheimer’s disease.

    Background Seasonal distribution of blood donation hinders efforts to provide a safe and adequate blood supply leading to chronic and persistent shortages. This study examined whether holidays, geographical area and donation type (community versus replacement) has any impact on the fluctuation of donations. Methods The numbers of blood donations from 2007 through 2010 in three Brazilian Retrovirus Epidemiological Donor Study II (REDS-II) participating centers were analyzed according to the week of donation. The weeks were classified as holiday or non-holiday. To compare donations performed during holiday versus non-holiday weeks, tabulations and descriptive statistics for weekly donations by blood center were examined and time series analysis was conducted. Results The average weekly number of donations varied according to the blood center and type of week. The average number of donations decreased significantly during Carnival and Christmas and increased during the Brazilian National Donor Week. The fluctuation was more pronounced in Recife and Belo Horizonte when compared to São Paulo and higher among community donors. Conclusion National bank holidays affect the blood supply by reducing available blood donations. Blood banks should take into account these oscillations in order to plan local campaigns, aiming at maintaining the blood supply at acceptable levels. PMID:24106441

    Current RFID technology deployment is limited by safety, procedural and physical limitations in healthcare field. It is important to define and ensure safe operation of technologies without actual deployment in real operation. Potential problems could arise due to the consequences of technical and physical characteristics of RFID technology and its improper location. This article deals with manipulation of blood products and the definition of suitable places for radio identification. Each suitable place must undergo laboratory experiments and tests. The results can provide a convenient base for defining efficient and safe deployment of RFID technology in Blood Centers with substantial financial savings for Czech healthcare.

    The assessment of suppliers of critical goods and services to European blood establishments is a regulatory requirement proving difficult to resource. This study was to establish whether European Blood Alliance member blood services could collaborate to reduce the cost of auditing suppliers without diminishing standards. Five blood services took part, each contributing a maximum of one qualified auditor per audit (rather than the usual two). Four audits were completed involving eight auditors in total to a European Blood Alliance agreed policy and process using an audit scope agreed with suppliers. Audits produced a total of 22 observations, the majority relating to good manufacturing practice and highlighted deficiencies in processes, procedures and quality records including complaints' handling, product recall, equipment calibration, management of change, facilities' maintenance and monitoring and business continuity. Auditors reported that audits had been useful to their service and all audits prompted a positive response from suppliers with satisfactory corrective action plans where applicable. Audit costs totalled € 3,438 (average € 860 per audit) which is no more than equivalent traditional audits. The four audit reports have been shared amongst the five participating blood establishments and benefitted 13 recipient departments in total. Previously, 13 separate audits would have been required by the five blood services. Collaborative supplier audit has proven an effective and efficient initiative that can reduce the resource requirements of both suppliers and individual blood service's auditing costs. Collaborative supplier audit has since been established within routine European Blood Alliance management practice.

  11. An examination of blood center structure and hospital customer satisfaction: what can centralized and decentralized blood centers learn from each other?

    PubMed

    Carden, Robert; DelliFraine, Jami L

    2005-01-01

    The cost of blood and blood products has increased rapidly over the last several years while the supply of available blood donors has simultaneously decreased. Higher blood costs and donor shortages have put a strain on the relationship between blood suppliers and their hospital customers. This study examines the association between blood center centralization or decentralization and several aspects of hospital satisfaction. Centralized and decentralized blood centers have significant differences in various aspects of hospital customer satisfaction. Advantages and disadvantages of the two structures are discussed, as well as areas for future research.

  13. Analysis of inventory strategies for blood components in a regional blood center using process simulation.

    2014-02-01

    The storage of blood components is an important concern in the blood supply chain. Because these are perishable products, the definition of good inventory policies is crucial to reduce shortages and spills. To analyze and propose inventory policies in a regional blood center, a discrete event simulation model was created using simulation software (Arena 12.0, Rockwell Software). The model replicates the activities that are performed along the supply chain including donation arrivals, testing, production, inventory management, and dispatching. Twelve different scenarios were analyzed, with each one representing different inventory policies composed of a combination of an optimal inventory, a reorder point, and a level of extra donations. The best scenario demonstrates that it is possible to decrease unsatisfied demand and wastage of red blood cell units by 2.5 and 3%, respectively, when compared to current practices. This study shows that simulation is an alternative that can be used to model inventory components in blood centers. A responsible selection of inventory variables can improve the capability of the system to respond to the final patient requirements. © 2013 American Association of Blood Banks.

    2013-03-01

    The Total Joint Center at The Miriam Hospital has been very successful and now serves as a model for other specialties. Key to this program’s success is the cooperative relationship between various stakeholders. Leadership is required yet the input and participation of all is necessary to achieve the desired outcome. To achieve efficiencies, there must be a willingness to deeply integrate clinical services. Again, this requires input from sectors that in the past typically did not communicate with each other. Finally, surgeons and staff need to "pledge" and show their willingness to practice based on sound patient data and modify treatment based on this same data. We are extremely proud of the results achieved. Also impressive is how, in a very short period of time, we have been able to bring together an extremely dedicated team of professionals who work cooperatively in a seamless fashion. With this approach we are able to meet our strategic goal of providing state-of-the-art, high quality, patient-centric, efficient healthcare.

    To study on the method for establishing the Qi stagnation and blood stasis rat model and analyze the affecting factors. The orthogonal design was adopted to study the influences of joint stimulations including noise, light, electricity, ice water bath, tail-clamping on model rats. The 'flying spot' method was used to dynamically simulate blood flow velocity in microcirculation. the pressure sensing technology of MOTO was adopted to detect hemorheology-related indicators. And the coagulation method was used to detect blood coagulation-related indicators. Compared with the negative control group, all model groups showed significant reduction in the blood flow velocity in mesenteric microcirculation and increase in the whole blood viscosity at high, medium and low shear rate, the plasma viscosity and the fibrinogen content in four blood coagulation indicators. Noise, light, electricity, tail-clamping, bondage and icewater-bath make significant impact on model rats.

    Ambulatory blood pressure monitoring (ABPM) is well established in adults and is becoming common in children. We reviewed 190 ABPM studies retrospectively (since 1990) to assess the failure rate, and analyzed the data from 97 patients 5-19 years old (1992-1996) to review the experience gained from the use of this technique in children and adolescents. Seventeen percent (32/190) of studies failed. Most children accepted ABPM, provided it was clearly explained in advance. There were differences between day and night readings of systolic blood pressure (BP), diastolic BP, and heart rate. BP did not correlate with height or weight. "White coat" effect apparently exists in children: clinic systolic BPs were higher than daytime systolic ABPM (no difference in diastolic). Eighty-nine percent (86/97) had an elevated BP load (>30% of readings >95th percentile). The antihypertensive medications of 16% (16/97) of patients were changed after ABPM. The nocturnal fall in BP (expressed as a percentage of the individual mean daytime values) was approximately normally distributed and was independent of age and height. Nocturnal systolic and diastolic dipping were closely correlated. Attenuation of nighttime dipping was observed in children with kidney disease and those with organ transplants. There is a need for normative data for ABPM for North American children. In our study, the technique was useful in selected cases, such as borderline or secondary hypertension, and for therapeutic monitoring when BP control is difficult.

    A building to serve as the operations, data gathering, and administrative complex and visitor center for the Southwest Residential Experiment Station (SW RES) was designed, constructed, and furnished as a cost-shared portion of a multiyear effort by the New Mexico Solar Energy Institute to establish and operate the SW RES for the Department of Energy National Photovoltaic Center Program. The 3000-square-foot building, called the Photovoltaic Center, houses a Visitor Center, shop area, offices, rest rooms, and a large data collection room. The passive solar design includes Earth berms, glazing along the southwest wall of the building and thermal mass in 55-gallon drums filled with water to store heat from solar radiation entering the building. The building is located on the New Mexico State University campus in Las Cruces.

    Threats to national and local blood supplies in America mandate development of an effective blood management system for emergency preparedness and efficient blood inventory management. Seasonal or acute blood shortages could be compounded by the unavoidable distribution inefficiencies of the blood pipeline during an emergency. The Yale-New Haven Hospital (YNHH) Blood Bank has developed a comprehensive emergency blood management plan, which includes maintenance of a tactical, limited frozen blood supply. A computer spreadsheet-based disaster prediction model has been designed to guide the use of the frozen reserve by testing various emergency scenarios. The frozen blood reserve can likely support normal hospital red blood cell (RBC) demands during typical (3-4 days) seasonal shortages, provide a reduced supply for up to 10 days, or meet an unexpected transient increased RBC demand without requiring intensive support from the regional blood center. However, the frozen blood supply is not designed to meet the massive transfusion demand associated with extreme or sustained disasters. Rather, it serves as a short-term bridge-over supply until blood center support can be reestablished. We review the reasons for initiating a blood management plan and describe how YNHH has implemented and sustains a frozen blood reserve as part of a comprehensive disaster management plan. Despite the operational complexity, the benefits of self-sufficiency, the ability to support routine hospital requirements, and the security of having a backup supply justify the expense and difficulty of maintaining a frozen blood reserve.

  16. Integrating molecular technologies for red blood cell typing and compatibility testing into blood centers and transfusion services.

    Nucleic acid-based technology is now at a point where the field of transfusion medicine is ready for its widespread application. In the donor center, genotyping of red blood cell (RBC) products provides phenotype-matched products for special patient populations or antigen-negative products for patients with alloantibodies. In the immunohematology reference laboratory, molecular technologies aid in discerning blood types in the situation of a typing discrepancy and improve pretransfusion RBC testing reagents. In the hospital transfusion service, genotyping patients aids in providing phenotype-matched RBC products. In prenatal testing, genotyping for RHD aids in the decision for Rh immune globulin prophylaxis and predicting risk of hemolytic disease of the fetus and newborn. Before genotyping is accepted as the universal standard for pretransfusion and donor testing, important limitations of this technology must be addressed, including the fact that the genotype does not always predict the phenotype and the need for creating the ideal high-throughput platform. Clinical trials are needed to answer important questions, and a donor and patient database is needed. A stepwise plan for progressive introduction into the donor centers and transfusion services must be established. In conclusion, the field of transfusion medicine is ready to expand the use of molecular diagnostics.

    Farmers' markets are community health promotion interventions that increase access to fresh fruits and vegetables. As farmers' markets continue to develop, it is important to strategically locate them in settings that are accessible to populations disparately affected by health disparities. One potential setting is a community health center. The goal of this analysis is to extend existing research on community readiness to identify indicators of preparedness among community health centers for establishing onsite farmers' markets. The sampling frame for the readiness assessment included all community health centers in South Carolina (N = 20) representing 163 practice sites. Data collection included two brief online surveys, in-depth key informant interviews, and secondary analysis of contextual data. Five themes related to readiness for establishing a farmers market at a community health center were identified: capacity, social capital, awareness of health problems and solutions, logistical factors, and sustainability. Findings from this study provide guidance to researchers and community health center staff as they explore the development of environmental interventions focused on reducing diet-related health conditions by improving access to healthy foods.

    Background Studies analyzing motivation factors that lead to blood donation have found altruism to be the primary motivation factor; however social capital has not been analyzed in this context. Our study examines the association between motivation factors (altruism, self-interest and response to direct appeal) and social capital (cognitive and structural) across three large blood centers in Brazil. Study Design and Methods We conducted a cross-sectional survey of 7,635 donor candidates from October 15 through November 20, 2009. Participants completed self-administered questionnaires on demographics, previous blood donation, HIV testing and knowledge, social capital and donor motivations. Enrollment was determined prior to the donor screening process. Results Among participants, 43.5% and 41.7% expressed high levels of altruism and response to direct appeal respectively, while only 26.9% expressed high levels of self-interest. More high self-interest was observed at Hemope-Recife (41.7%). Of participants, 37.4% expressed high levels of cognitive social capital while 19.2% expressed high levels of structural social capital. More high cognitive and structural social capital was observed at Hemope-Recife (47.3% and 21.3%, respectively). High cognitive social capital was associated with high levels of altruism, self-interest and response to direct appeal. Philanthropic and high social altruism was associated with high levels of altruism and response to direct appeal. Conclusion Cognitive and structural social capital and social altruism are associated with altruism and response to direct appeal, while only cognitive social capital is associated with self-interest. Designing marketing campaigns with these aspects in mind may help blood banks attract potential blood donors more efficiently. PMID:22998740

    The screening laboratory has a critical role in the post-transfusion safety. The success of its targets and efficiency depends on the management system used. Even though the European Union directive 2002/98/EC requires a quality management system in blood establishments, its requirements for screening laboratories are generic. Complementary approaches are needed to implement a quality management system focused on screening laboratories. This article briefly discusses the current good manufacturing practices and good laboratory practices, as well as the trends in quality management system standards. ISO 9001 is widely accepted in some European Union blood establishments as the quality management standard, however this is not synonymous of its successful application. The ISO "risk-based thinking" is interrelated with the quality risk-management process of the EuBIS "Standards and criteria for the inspection of blood establishments". ISO 15189 should be the next step on the quality assurance of a screening laboratory, since it is focused on medical laboratory. To standardize the quality management systems in blood establishments' screening laboratories, new national and European claims focused on technical requirements following ISO 15189 is needed.

    Introduction The World Health Organization (WHO) recommends the creation of national blood transfusion services. Burkina Faso has a CNTS (Centre national de transfusion sanguine - National Blood Transfusion Center) but it currently covers only 53% of the national blood supply versus 47% produced by independent hospital blood banks. Study design To evaluate blood collection, testing, preparation and prescription practices in the regions of Burkina Faso that are not covered by the CNTS, we conducted a cross-sectional survey. Methodology Data were collected by trained professionals from May to June 2009, at 42 autonomous blood centers not covered by the CNTS. Results Blood collection was supervised in all sites by laboratory technicians without specific training. There was no marketing of community blood donation nor mobile collection. Donation was restricted to replacement (family) donors in 21.4% of sites. Pre-donation screening of donors was performed in 63.4% of sites, but some did not use written questionnaires. Testing for HIV, hepatitis B virus and syphilis was universal, although some sites did not screen for hepatitis C virus. In 83.3% of the sites blood typing was performed without reverse ABO typing. In 97.6% of the sites, nurses acted alone or in conjunction with a physician to order blood transfusions. Conclusion Shortcomings in non-CNTS blood centers argue for the development of a truly national CNTS. Such a national center should coordinate and supervise all blood transfusion activities, and is the essential first step for improving and institutionalizing blood transfusion safety and efficacy in a developing country.

    To establish a new method for detection of red blood cell osmotic fragility by using flow cytometry. The hypotension salt solution of different concentrations (0.70 ml normal saline+0.3 ml deionized water, 0.60 ml normal saline+0.40 ml deionized water and 0.55 ml normal saline+0.45 ml deionized water) were prepared with normal saline and deionized water, in which the red blood cells were suspended, and the residual red blood cells were detected by flow cytometer. There was no significant difference in percentage of residual red blood cells between different time points detected by flow cytometer in 3 different hypotonic salt solutions. The percentage of residual red blood cells in B+C+D+E+F+G detected time region was different among 3 NaCl dilution groups. The percentage of residual red blood cells in normal control was lower than that in hemoglobinopathy group. The percentage of residual red blood cells in hereditary spherocytosis (HS) group was obviously lower than that in hemoglobinopathy and normal control groups. The comparison of 3 different dilution concentrations found that the second concentration (0.60 ml normal saline+0.40 ml deionized water) is more suitable to screen HS by FC500 flow cytometer. The detection of red cell osmotic fragility by using flow cytometry is a simple, rapid, objective and economic way that can be an effective screening method for diagnose the HS.

    At the present of the 21st century, optical technology became what must be in our life. If there is no optical technology, we cannot use optical equipments such as the camera, microscopes, DVD, LEDs and laser diodes (LDs). Optics is also the leading part in the most advanced scientific field. It is clear that the organization which does education and research is required in such a very important area. Unfortunately, there was no such organization in Japan. The education and research of light have been individually done in various faculties of universities, various research institutes, and many companies. However, our country is now placed in severer surroundings, such as the globalization of our living, the accelerated competition in research and development. This is one of the reasons why Utsunomiya University has established Center for Optical Research and Education (CORE) in 2007. To contribute to optical technology and further development of optical industry, "Center for Optical Research and Education (CORE), Utsunomiya University" promotes education and research in the field of the optical science and technology cooperatively with industry, academia and the government. Currently, 6 full professors, 21 cooperative professors, 2 visiting professors and 7 post-doctoral researchers and about 40 students are joined with CORE. Many research projects with industries, the local government of Tochigi as well as Japanese government. Optical Innovation Center has established in CORE by supporting of Japan Science and Technology Agency in 2011 to develop advanced optical technologies for local companies.

    During the past four decades, many tissue banks have been established across the world with the aim of supplying sterilized tissues for clinical use and research purposes. Between 1972 and 2005, the International Atomic Energy Agency supported the establishment of more than sixty of these tissue banks in Latin America and the Caribbean, Asia and the Pacific, Africa and Eastern Europe; promoted the use of the ionizing radiation technique for the sterilization of the processed tissues; and encouraged cooperation between the established tissue banks during the implementation of its program on radiation and tissue banking at national, regional and international levels. Taking into account that several of the established tissue banks have gained a rich experience in the procurement, processing, sterilization, storage, and medical use of sterilized tissues, it is time now to strengthen further international and regional cooperation among interested tissue banks located in different countries. The purpose of this cooperation is to share the experience gained by these banks in the procurement, processing, sterilization, storage, and used of different types of tissues in certain medical treatments and research activities. This could be done through the establishment of a network of tissue banks and a limited number of regional tissue processing centers in different regions of the world.

    The US Nuclear Regulatory Commission has initiated a Structural aging Program at the Oak Ridge National Laboratory to identify potential structural safety issues related to continued service of nuclear power plants and to establish criteria for evaluating and resolving these issues. One of the tasks in this program focuses on the establishment of a Structural Materials Information Center where data and information on the time variation of concrete and concrete-related material properties under the influence of pertinent environmental stressors and aging factors will be collected and assembled into a database. This database will be used to assist in the prediction of potential long-term deterioration of critical structural components in nuclear power plants and to establish limits on hostile environmental exposure for these structures and materials. Materials property data and information will be collected at the Structural Materials Information Center from open literature, published references, and identifiable sources. Initially, the database will include portland cement concrete, metallic reinforcement, prestressing tendon and structural steel materials. Then, as data and information for other material systems are obtained, the database will be expanded and updated. The database will be developed and presented in two complementary formats. The Structural Materials Handbook will be published in four volumes as an expandable, hard copy handbook. The Materials Electronic Database will be developed to reflect the same information as contained in the handbook, but will be formatted for use on an IBM or IBM-compatible personal computer.

    One focus of improvement of burn care in Ukraine was the management of blood loss and blood transfusions in burn patients. The aim of this project was to analyze blood transfusion triggers in burn patients and outcomes at eleven major burn centers in Ukraine. This multicenter retrospective study reviewed four years of data on blood-transfused burn patients admitted to eleven major burn centers in Ukraine. Data analyzed included: demographics, characteristics of the burns, complications of burn injury, triggers for blood transfusions and outcomes. A total of 928 burn patients who received 2,693 blood transfusions from 11 major burn centers over a four-year period, were studied. Regardless of the total body surface area (TBSA) that was burned, blood transfusions were administered with a hemoglobin (Hb) trigger value of around 9 g/dL. Roughly one third (30.5%) of all transfusions were given in patients with a TBSA ≤ 10%. We demonstrated that Ukrainian doctors were using the same Hb trigger for blood transfusions for all Ukrainian burn patients, which suggested a need to change blood transfusion policy.

    Presented at the WINDPOWER 2010 Conference & Exhibition, 23-26 May 2010, Dallas, Texas. The rapid growth of the small wind turbine (SWT) market is attracting numerous entrants. Small wind turbine purchasers now have many options but often lack information (such as third-party certification) to select a quality turbine. Most SWTs do not have third-party certification due to the expense and difficulty of the certification process. Until recently, the only SWT certification bodies were in Europe. In North America, testing has been limited to U.S. Department of Energy (DOE) subsidized tests conducted at the National Wind Technology Center (NWTC) under the ongoing Independent Testing Project. The goal is to increase the number of certified turbines and gain greater consumer confidence in SWT technology. To reduce certification testing costs, DOE/NREL is assisting in establishing a network of Regional Test Centers (RTCs) to conduct SWT third-party certification testing. To jump-start these RTCs, DOE/NREL is providing financial and technical assistance for an initial round of tests. The goal is to establish a lower-cost U.S. small wind testing capability that will lead to increased SWT certification. This poster describes the project, describes how it fits within broader SWT certification activities, and provides current status.

    In 2008, the Ministry of Health and Welfare of South Korea initiated the Regional Comprehensive Stroke Center (CSC) program to decrease the incidence and mortality of stroke nationwide. We evaluated the performance of acute ischemic stroke management after the Regional CSC program was introduced. The Ministry of Health and Welfare established 9 Regional CSCs in different provinces from 2008 to 2010. All Regional CSCs have been able to execute the critical processes independently for stroke management since 2011. The Ministry of Health and Welfare was responsible for program development and financial support, the Regional CSC for program execution, and the Korea Centers for Disease Control and Prevention for auditing the execution. We analyzed prospectively collected data on the required indices from 2011 and repeated the analysis the following year for comparison. After the Regional CSCs were established, the first brain image was taken within 1 hour from arrival at the emergency room for all patients with stroke; the length of hospital stay decreased from 14 to 12 days; for the rapid execution of thrombolysis, the first brain image was taken within 12 minutes; intravenous and intra-arterial thrombolysis were started within 40 and 110 minutes, respectively, after emergency room arrival; and the hospital stay of thrombolytic patients decreased from 19 to 15 days. The Regional CSC program has improved the performance of acute stroke management in South Korea and can be used as a model for rapidly improving stroke management. © 2014 American Heart Association, Inc.

    In 2008, the National Library of Medicine (NLM) established the Disaster Information Management Research Center (DIMRC). Prior to 2008, NLM had a long history of involvement in providing health information for disaster management. Aware of this legacy and moved by the catastrophic aftermath of Hurricane Katrina, the NLM long range plan (Charting a Course for the 21st Century: NLM’s Long Range Plan 2006–2016) called for creation of a center to show “a strong commitment to disaster remediation and to provide a platform for demonstrating how libraries and librarians can be part of the solution to this national problem”. NLM was urged to “ensure continuous access to health information and effective use of libraries and librarians when disasters occur”. In response to this charge, NLM has undertaken substantial efforts to ensure that medical libraries have plans for the continuity of their operations, librarians are trained to understand their roles in preparedness and response, online disaster health information resources are available for many audiences and in multiple formats, and research is conducted on tools to enhance the exchange of critical information during and following disasters. This paper documents the history, goals, initiatives, accomplishments and future plans of the Center. PMID:25324584

    Haemoglobin concentration in blood is one of the most frequently measured analytes in laboratory medicine. Reference and routine methods for the determination of the haemoglobin concentration in blood are based on the conversion of haeme, haemoglobin and haemiglobin species into uniform end products. The total haemoglobin concentration in blood is measured using the absorbance of the reaction products. Traceable absorbance measurement values on the highest metrological level are a prerequisite for the calibration and evaluation of procedures with respect to their suitability for routine measurements and their potential as reference measurement procedures. For this purpose, we describe a procedure to establish traceability of spectral absorbance measurements for the haemiglobincyanide (HiCN) method and for the alkaline haematin detergent (AHD) method. The latter is characterized by a higher stability of the reaction product. In addition, the toxic hazard of cyanide, which binds to the iron ion of the haem group and thus inhibits the oxygen transport, is avoided. Traceability is established at different wavelengths by applying total least-squares analysis to derive the conventional quantity values for the absorbance from the measured values. Extrapolation and interpolation are applied to get access to the spectral regions required to characterize the Q-absorption bands of the HiCN and AHD methods, respectively. For absorbance values between 0.3 and 1.8, the contributions of absorbance measurements to the total expanded uncertainties (95% level of confidence) of absorbance measurements range from 1% to 0.4%.

    Blood centers without fixed appointments for collecting blood often experience nonconstant donor arrival rates, which vary due to time-of-day, day-of-week, etc. When a constant workforce size is employed in such blood centers, there is either idle personnel, or donor satisfaction is compromised due to long waiting times, or both conditions alternate over time. Consequently, a method to obtain adaptive workforce requirements might be valuable. This study utilized the Two-Step Cluster method and the Classification and Regression Trees method in succession to identify both daily and hourly donor arrival patterns at Hacettepe University Hospitals' Blood Center. A serial queuing network model of the donation process was then employed for each of the identified donor arrival patterns. By considering and accommodating variations in the donor arrival patterns, required workforce sizes and their decomposition among process steps were predicted to achieve predetermined target values of expected waiting times and to balance workforce utilizations in the blood donation processes. Although a blood center is considered for the proposed methodology, the approach is general and applications in various operations of healthcare organizations are possible.

    To combine community and hospital services in order to enable improvements in patient management, an integrated gastroenterology service (IGS) was established. Referral patterns to specialist clinics were optimized; open access route for endoscopic procedures (including esophago-gastro-duodenoscopy, sigmoidoscopy and colonoscopy) was established; family physicians' knowledge and confidence were enhanced; direct communication lines between experts and primary care physicians were opened. Continuing education, guidelines and agreed instructions for referral were promoted by the IGS. Six quality indicators were developed by the Delphi method, rigorously designed and regularly monitored. Improvement was assessed by comparing 2010, 2011 and 2012 indicators. An integrated delivery system in a specific medical field may provide a solution to a fragmented healthcare system impaired by a lack of coordination. In this paper we describe a new integrated gastroenterology service established in April 2010. Waiting time for procedures decreased: 3 mo in April 30th 2010 to 3 wk in April 30th 2011 and stayed between 1-3 wk till December 30th 2012. Average cost for patient's visit decreased from 691 to 638 NIS (a decrease of 7.6%). Six health indicators were improved significantly comparing 2010 to 2012, 2.5% to 67.5%: Bone densitometry for patients with inflammatory bowel disease, preventive medications for high risk patients on aspirin/NSAIDs, colonoscopy following positive fecal occult blood test, gastroscopy in Barrett's esophagus, documentation of family history of colorectal cancer, and colonoscopy in patients with a family history of colorectal cancer. Establishment of an IGS was found to effectively improve quality of care, while being cost-effective.

These efforts were unique in that the activities undertaken prior to the conference were extensive, and effectively laid the groundwork for productive technology transfer following, and as a direct result of, the conferences. The effort leading to the conference was in each case tailored to the characteristics of the potential user community, however, the common factors comprise a basic framework applicable to similar endeavors. The process is essentially a planned sequence of steps that constitute a technical market survey and a marketing program for the development of beneficial applications of aerospace technology beyond the aerospace field.

    Background and Objective: The implementation of quality system and continuous evaluation of all activities of the Blood Transfusion Services (BTS) can help to achieve the maximum quantity and quality of safe blood. Optimizing blood collection and processing would reduce the rate of discard and improve the efficiency of the BTS. The objective of this study is to determine the rate of discard of blood and blood component and identify its reasons at the National Blood Centre (NBC), Kuala Lumpur, during the year of 2007 in order to introduce appropriate intervention. Study Designs and Methods: Data on the number of discarded whole blood units and its components, reasons for discard, and the number of blood components processed as well as the number of collected blood units were obtained from the Blood Bank Information System - NBC database. These were analyzed. Results: The total number of blood units collected in 2007 was 171169 from which 390636 units of components were prepared. The total number of discarded whole blood units and its components was 8968 (2.3%). Platelet concentrate recorded the highest of discard at 6% (3909) followed by whole blood at 3.7% (647), fresh frozen plasma (FFP) at 2.5% (2839), and cryoprecipitate at 2% (620). The rate of discarded packed red blood cells RBCs, plasma aphaeresis, and PLT aphaeresis was less than 1% at 0.6% (902), 0.6% (37), and 0.29% (14), respectively. RBC contamination of PLT and plasma were the major cause of discard at 40% (3558). Other causes include leakage (26% - 2306), lipemia (25% - 2208), and underweight (4% - 353). Conclusion: Good donor selection, training and evaluation of the staff, as well as implementation of automation will help to improve processes and output of BTS. This would reduce discard of blood components and wastage caused by non conformance. PMID:22623837

    The aim of our study was to assess the fetal RBC count in maternal blood during uncomplicated pregnancies from 26 weeks onward. We used a flow cytometric method specifically designed for use in a routine hematology analyzer. Pregnant women were recruited through midwives. The participating laboratories used the FMH QuikQuant method (Trillium Diagnostics, Brewer, ME) in a CELL-DYN Sapphire hematology analyzer (Abbott Diagnostics, Santa Clara, CA). The method is based on a monoclonal antibody to hemoglobin F. Flow cytometric data were analyzed by 2 independent observers. The 95th percentile reference range was estimated according to Clinical and Laboratory Standards Institute guidelines. A total of 236 samples were statistically analyzed. Gestational ages ranged from 21.6 to 41 weeks (mean, 32.0 weeks), and the fetal RBC count in maternal blood ranged from 0.00% to 0.50% (median, 0.025%). The fetal RBC count in maternal blood shows no correlation with gestational age. The established reference range during normal pregnancy is less than 0.125%.

    Objectives: To assess the outcomes of different types of bariatric surgeries in a single newly established private obesity center. Methods: Retrospectively, we included patients who were entered in the registry for bariatric surgeries in the Obesity Unit, Riyadh National Hospital, Riyadh, Saudi Arabia between January 2013 and September 2014, and completed one year of follow up. Baseline characteristics, percent excess weight loss, and safety data were collected and analyzed. Results: A total of 79 patients were included. Based on the type of surgery, patients were divided into 3 groups: laparoscopic Roux-en-Y gastric bypass (RYGB), laparoscopic minigastric bypass (MGBP), and laparoscopic vertical sleeve gastrectomy (SG). After one year, RYGB and MGB patients lost more weight than SG patients. No mortality, or leak were reported and one patient had reoperation after revision laparoscopic RYGB for bleeding. There was one readmission, while 4 patients visited the emergency room for vomiting and dehydration (2 patients), anemia (one patient), and port site infection (one patient). Conclusion: Bariatric surgeries are safe when carried out by an experienced bariatric surgeon in the private sector. The outcome of this series is similar to the published results from large international obesity databases. PMID:27652359

    PubMed

    Murakami, Masaaki

    We have been studying about the molecular mechanism responsible for the establishment of the blood-vessel gateway through which immune cells enter the CNS. We have discovered three kinds of gateways in a multiple sclerosis model, EAE, based on the neural stimulations and named them the gravity-gateway reflex, electric-gateway reflex, and pain-gateway reflex, respectively. All gateway reflexes are involved in specific crosstalk between sensory-sympathetic pathways. For example, in the gravity-gateway reflex, gravity-mediated sensory stimulation via the soleus muscles activates fifth lumber(L5)dorsal loot ganglions to activate L5 sympathetic ganglions, which express norepinephrine at specific vessels of the L5 cord. We explain these three types of gateway reflexes in this chapter.

    Objectives: It is quite common to have advanced cancer or end-stage renal disease patients for regular or even frequent blood transfusion in palliative care. However, due to geographical reason in some hospice centers, blood transfusion is sometimes difficult if blood bank is closed during non-office hour or not available. Methods: Here, we reported a new blood releasing system, that is, remote blood releasing system, that could be used safely by nursing staff alone when the blood bank was closed during the night time and holiday. Results: On-call nursing staff could collect red cells successful in these two cases. Conclusion: The new blood releasing system seems useful. However, larger sample sizes and longer period of study are required to estimate its efficacy and safety. The provision of antibody-positive red cells and platelet remained a limitation of this system. PMID:27489720

    The growing use of group AB plasma in the United States in recent years poses unique challenges to blood centers and transfusion services. Blood centers must collect sufficient plasma components from a limited pool of group AB donors while taking steps to improve transfusion safety that further restricts the available supply. Transfusion services, on the other hand, must use the finite resource in the most conscientious and medically appropriate manner. Recently, many investigations have challenged long-held beliefs about transfusion practice and appropriate indications for blood components across a variety of specialties. Balancing supply and demand of group AB plasma requires collaboration between blood suppliers and transfusion services, and opportunities for improvement exist on both sides of the equation. © 2013 American Association of Blood Banks.

    Transfusion of red blood cells (RBCs) is a standard and indispensable therapy in current clinical practice. In vitro production of RBCs offers a potential means to overcome a shortage of transfusable RBCs in some clinical situations and also to provide a source of cells free from possible infection or contamination by microorganisms. Thus, in vitro production of RBCs may become a standard procedure in the future. We previously reported the successful establishment of immortalized mouse erythroid progenitor cell lines that were able to produce mature RBCs very efficiently. Here, we have developed a reliable protocol for establishing immortalized human erythroid progenitor cell lines that are able to produce enucleated RBCs. These immortalized cell lines produce functional hemoglobin and express erythroid-specific markers, and these markers are upregulated following induction of differentiation in vitro. Most importantly, these immortalized cell lines all produce enucleated RBCs after induction of differentiation in vitro, although the efficiency of producing enucleated RBCs remains to be improved further. To the best of our knowledge, this is the first demonstration of the feasibility of using immortalized human erythroid progenitor cell lines as an ex vivo source for production of enucleated RBCs.

    The blood supply chain is a complex system that considers different interconnected elements that have to be synchronized correctly to satisfy in quality and quantity the final patient requirements. To determine the blood center maximum production capacity, as well as the determination of the necessary changes for a future production capacity expansion. This work was developed in the Blood Center of Concepción, Chile, operations management tools were applied to model it and to propose improvement alternatives for the production process. The use of simulation is highlighted, which permitted the replication of the center behavior and the evaluation of expansion alternatives. It is possible to absorb a 100% increment in blood demand, without making major changes or investments in the production process. Also it was possible to determine the subsequent steps in terms of investments in equipment and human resources for a future expansion of the center coverage. The techniques used to model the production process of the blood center of Concepción, Chile, allowed us to analyze how it operates, to detect "bottle necks", and to support the decision making process for a future expansion of its capacity.

    2015 marks the 27th year that the Lyme Disease Diagnostic Center, located in New York State in the United States, has provided care for patients with suspected or established deer tick-transmitted infections. There are five deer tick-transmitted infectious in this geographic area of which Lyme disease is the most common.For patients with erythema migrans, we do not obtain any laboratory testing. However, if the patient is febrile at the time of the visit or reports rigors and high-grade fevers, we consider the possibility of a co-infection and order pertinent laboratory tests.Our preferred management for Lyme disease-related facial palsy and/or radiculopathy is a 2-week course of doxycycline. Patients who are hospitalized for Lyme meningitis are usually treated at least initially with ceftriaxone. We have not seen convincing cases of encephalitis or myelitis solely due to Borrelia burgdorferi infection in the absence of laboratory evidence of concomitant deer tick virus infection (Powassan virus). We have also never seen Lyme encephalopathy or a diffuse axonal peripheral neuropathy and suggest that these entities are either very rare or nonexistent.We have found that Lyme disease rarely presents with fever without other objective clinical manifestations. Prior cases attributed to Lyme disease may have overlooked an asymptomatic erythema migrans skin lesion or the diagnosis may have been based on nonspecific IgM seroreactivity. More research is needed on the appropriate management and significance of IgG seropositivity in asymptomatic patients who have no history of Lyme disease.

    In Taiwan, the number of the patients needing dialysis increases rapidly in recent years. Because there is risk in every hemodialysis session, monitoring physiological status, such as blood pressure measurement every 30 min to 1 h is needed during about 4 h hemodialysis process. Therefore, an assisted measurement on blood pressure is needful in dialysis care centers. Telecare system (TCS) is regarded as one of important technique in the medical care. In this study, we utilized ZigBee wireless technique to establish a mesh network for monitoring blood pressure automatically and data storage in medical record system for display and further analysis. Moreover, while the blood pressure exceeds the normal range, the system could send a warning signal to remind, or inform the relatives and clinicians in health care center through the personal handy-phone system (PHS) immediately. The proposed system provides an assisted device for monitoring patients' blood pressure during hemodialysis process and saving medical manpower.

    The authors assessed the process of blood pressure (BP) measurement and level of adherence to recommended procedures at representative sites throughout a large academic health sciences center. A casual observer assessed the setting and observed the process, noting the equipment, technique, and BP recorded by site personnel. A trained observer then repeated the patient's BP measurement following American Heart Association recommendations. Significant biases were observed between measurements by site personnel and the trained observer. Site personnel reported on average an increased systolic BP (SBP) of 5.66 mm Hg (95% confidence interval [CI], 3.09-8.23; P<.001) and a decreased diastolic BP (DBP) of -2.96 mm Hg (95% CI, -5.05 to -0.87; P=.005). Overall, 41% of patients had a ≥10-mm Hg difference in SBP between measurements. Similarly, 54% had differences of ≥5 mm Hg in DBP between measurements. Inaccurate BP measurement and poor technique may lead to misclassification, misdiagnosis, and inappropriate medical decisions. Concordance of measured SBP between our site personnel and trained observer was less than optimal. Several areas for improvement were identified. Routine calibration and use of system-wide standardized equipment, establishment of BP measurement protocols, and periodic technique and equipment recertification can be addressed in future quality initiatives.

    This study analyzes trends in hospitalization and outcome for adult, elderly, and pediatric trauma victims in the Florida Trauma System (FTS) from 1991 to 2003, during which time the number of centers nearly doubled from 11 to 20. Administrative data was queried for all admissions with at least one trauma related discharge. Patients were stratified by age as pediatric (age, 0 to 15 years), adult (age, 16 to 64 years), or elderly (age, >64 years). Volume of admissions, severity, and mortality were analyzed over time. A logistic regression model was used to test the existence of an organizational experience curve after the designation of a new trauma center. Injury-related hospitalizations increased for the elderly, stayed the same for adults, and declined for children. As the system matured, a larger percentage of victims, particularly the most severely injured, were triaged to trauma centers, indicating more effective triage. In contrast to adults and pediatric patients, the majority of elderly trauma victims were managed at non-trauma centers. The trauma mortality rate per 1,000 population among the elderly increased during the study period (P < .01). Multivariate analysis indicated that for adult and pediatric victims it took up to 3 years after the designation of trauma center status before the odds of mortality reached parity with that of established centers. The FTS has grown with its population and has matured to treat a larger percentage of trauma victims. Trauma victims transported to established trauma centers (4+ years) have a survival advantage compared to their counterparts transported to newly created centers. The reduction in the odds of mortality does not occur immediately after trauma center designation.

    Blood and its derivatives are one of the most lifesaving products in the modern medicine practice. However, it is not an absolutely safe prescription. Many adverse effects such as infection, transfusion-related acute lung injury, immunosuppression, multi-organ dysfunction, acute respiratory syndrome, transfusion errors, transmission of infectious agents such as HIV, HBV, HCV are attributable to blood transfusion. The aim of this study was to describe how and when blood products were transfused in a referral burn center. This cross-sectional study was performed on medical records of all admitted patients in the Department of Burns and Reconstructive Surgery of Imam Reza Hospital, Mashhad, Iran during September 2014 up to August 2015. Transfusion measures such as Hb, Hct and demographic data were extracted from patient records. SPSS version 11.5 was used for data analysis. During the study period, 701 acute burnt patients were admitted with the mean age of 25.5±20.5 years. Sixty-four percent were male and burnt percentage of total body surface area (TBSA) was 30.9±24.3%. About one third (240) of patients received at least one blood product. Mean of the transfused packed red blood cell was 274.1±674.6mL per patient and 8.85mL per 1% of burnt TBSA. Anemia was the most common transfusion trigger. Mortality in burnt patients who received blood products was two folds more than patients who did not receive any blood products. We prescribed less blood products compared with other reviewed burn centers. However, following a written blood transfusion protocol by all clinicians may reduce blood transfusion in unnecessary situations even more significantly. Copyright © 2017 Elsevier Masson SAS.

    Integrating primary care with behavioral health services at community mental health centers is one response to the disparity in mortality and morbidity experienced by adults with serious mental illnesses and co-occurring substance use disorders. Many integration models have been developed in response to the Primary and Behavioral Health Care Integration (PBHCI) initiative of the Substance Abuse and Mental Health Services Administration (SAMHSA). One model is a primary care clinic co-located within the mental health center. The Connecticut Mental Health Center (CMHC) Wellness Center is one such co-located clinic developed as a partnership between CMHC and a Federally Qualified Health Center (FQHC). In this article, we describe the process of developing this on-site clinic along with lessons learned during implementation. We review different aspects of building and maintaining such a clinic and outline lessons learned from both successes and challenges. We briefly describe the demographics and health characteristics of the patient population served in this clinic. We make recommendations for providers and agencies that are considering or are already developing a model for integrating care. Finally, we briefly review status of our clinic after completion of grant funding.

    The non-Treponemal tests such as Rapid Plasma Reagin test (RPR) or the Venereal Disease Reference Laboratory test are the most commonly used test for screening of syphilis in the blood centers in India. Now, with the availability of Enzyme-linked immunosorbent assay (ELISA) and Immunochromatographic assays in the market, we decided to evaluate these assays in comparison with Treponema pallidum Haemagglutination Assay (TPHA) which was considered as a gold standard for this study. A total of 8 685 samples of voluntary blood donors were tested on Trepolisa 3.0 and then the initially reactive samples were retested in duplicate on the same assay as well as on Omega Pathozyme, RPR, RAPHA (Rapid Anti-Treponema pallidum Assay), and TPHA. Of the 158 initially reactive samples, 104 were repeatedly reactive on the same assay, 85 were reactive with RPR, 77 were reactive with RAPHA, 60 were reactive on Omega, and 53 were confirmed reactive on TPHA. 48 (56.4%) of the results on RPR were biological false positive, while 21.9% of results were false negative on RPR. We evaluated that Omega Pathozyme was quite in agreement with TPHA as compared with Trepolisa 3.0, RAPHA, and RPR. We concluded that Omega Pathozyme (ELISA) can be considered as a suitable test for screening of syphilis in a blood center. PMID:22623840

    In fewer than five years, the University of Kansas Hospital Spine Center became the largest and most comprehensive spine care facility in the greater metropolitan Kansas City area. The 22,000-square-foot facility has 27 exam rooms, four specialized diagnostic rooms, 11 pre-/post-interventional procedure rooms, and a 4000-square-foot outpatient rehabilitation gym. Patients can meet with their physicians, undergo diagnostic tests and treatment, and attend therapy sessions in one location. The multidisciplinary Spine Center brings together orthopedic surgeons, neurosurgeons, neurologists, physical medicine and rehabilitation physicians, psychiatrists, psychologists, pain-management anesthesiologists, radiologists, and physical and occupational therapists. The Spine Center became successful because a group of physicians bought into the philosophy of a comprehensive interdisciplinary program, were willing to sacrifice some territorial claims, and were willing to put patient care and the good of the institution above individual egos.

    Integrative medicine (IM) refers to the combination of conventional and "complementary" medical services (e.g., chiropractic, acupuncture, massage, mindfulness training). More than half of all medical schools in the United States and Canada have programs in IM, and more than 30 academic health centers currently deliver multidisciplinary IM care. What remains unclear, however, is the ideal delivery model (or models) whereby individuals can responsibly access IM care safely, effectively, and reproducibly in a coordinated and cost-effective way.Current models of IM across existing clinical centers vary tremendously in their organizational settings, principal clinical focus, and services provided; practitioner team composition and training; incorporation of research activities and educational programs; and administrative organization (e.g., reporting structure, use of medical records, scope of clinical practice) and financial strategies (i.e., specific business plans and models for sustainability).In this article, the authors address these important strategic issues by sharing lessons learned from the design and implementation of an IM facility within an academic teaching hospital, the Brigham and Women's Hospital at Harvard Medical School; and review alternative options based on information about IM centers across the United States.The authors conclude that there is currently no consensus as to how integrative care models should be optimally organized, implemented, replicated, assessed, and funded. The time may be right for prospective research in "best practices" across emerging models of IM care nationally in an effort to standardize, refine, and replicate them in preparation for rigorous cost-effectiveness evaluations.

    When problems with compatibility beyond ABO and D arise, currently transfusion services search their inventories and perform time-consuming serologic testing to locate antigen-negative blood. These clinically important blood group antigens can be detected reliably by red cell genotyping, which is a technology whereby DNA-based techniques are used to evaluate gene polymorphisms that determine the expression of blood group antigens. We introduced mass-scale genotyping and measured availability of genotyped blood. All non-Caucasian donors qualified for genotyping along with donors who had a history of repeat donation. Mass-scale red cell genotyping, performed on an electronic interfaced open array platform, was implemented to screen blood donors for 32 single-nucleotide polymorphisms that predicted 42 blood group antigens. Genotype screening results were confirmed by phenotyping, when needed for antigen-negative transfusion, before release of the red blood cell (RBC) unit. Approximately 22,000 donors were red cell genotyped within 4 months and a total of 43,066 donors in 4 years. There were 463 discordances (0.52% of 89,596 genotypes with a phenotype). Among the 307 resolved discordances, approximate equal numbers represented historical serologic or genotyping discrepancies (n = 151 and n = 156, respectively). In the final year of the study, a mean of 29% of the daily inventory had a genotype. Red cell genotyping of blood donors using an electronic interface created a large and stable supply of RBC units with historical genotypes. The database served the needs of antigen-negative blood requests for a large regional blood center and allowed us to abandon screening by serology. © 2015 AABB.

    Pathogen reduction technology is an important process in the blood safety system, including solvent/detergent treatment, filtration and methylene blue-photochemical technology (MB-PCT). To investigate the quality of MB-PCT-treated plasma, plasma samples from four Chinese blood centers were analyzed over 12 months of storage to determine the recovery of activities and levels of various plasma proteins. Ten plasma units each from the Suzhou, Yancheng, Chongqing and Shandong blood centers were divided into two aliquots. One was subjected to treatment with one of two methylene blue-photochemical technology instruments and the other was used as control. The treated and untreated sample pairs were stored at -30°C. The recovery rates of coagulation factors, inhibitor proteins, total protein, immunoglobulins, and complement proteins were measured at different time points after storage. The mean recovery of most proteins exceeded 80% after MB treatment. The exceptions were factor XI and fibrinogen, of which only 71.3-74% and 69.0-92.3% were retained during storage. The two equipment types differed in terms of residual MB concentration in the plasma samples (0.18 μM and 0.29 μM, respectively). They had similar protein recovery rates at 0.5 month but differed at later time points. The four blood centers differed significantly with regard to factor II, V, VIII and fibrinogen activities. Only the samples from the Shandong blood center met the methylene blue treated fresh frozen plasma requirement. The major factor that influenced the quality of the MB-FFP samples was the time taken between blood collection and storage. Methylene blue treated plasma showed reduced coagulation factor (CF) activity and protein levels. The MB treatment-induced damage to the proteins was acceptable at the four Chinese blood centers, but the quality of the MB-treated plasma in general was not satisfactory. The main factor affecting plasma quality may be the duration of the collection and

  12. Selective ablation of immature blood vessels in established human tumors follows vascular endothelial growth factor withdrawal.

    Features that distinguish tumor vasculatures from normal blood vessels are sought to enable the destruction of preformed tumor vessels. We show that blood vessels in both a xenografted tumor and primary human tumors contain a sizable fraction of immature blood vessels that have not yet recruited periendothelial cells. These immature vessels are selectively obliterated as a consequence of vascular endothelial growth factor (VEGF) withdrawal. In a xenografted glioma, the selective vulnerability of immature vessels to VEGF loss was demonstrated by downregulating VEGF transgene expression using a tetracycline-regulated expression system. In human prostate cancer, the constitutive production of VEGF by the glandular epithelium was suppressed as a consequence of androgen-ablation therapy. VEGF loss led, in turn, to selective apoptosis of endothelial cells in vessels devoid of periendothelial cells. These results suggest that the unique dependence on VEGF of blood vessels lacking periendothelial cells can be exploited to reduce an existing tumor vasculature.

    The relationship between faculty in academic health centers (AHCs) and commercial entities is critically important to improving the public health, yet it may be prone to conflicts of interest that adversely affect medical education, research, and clinical care. The Association of American Medical Colleges has recently recommended that medical schools and AHCs develop policies that better manage and occasionally prohibit interactions between academic medicine and industry. Because the development of more stringent policies is complex and potentially contentious, the author reports the lessons learned from developing new policies for the interactions between faculty and industry related to medical education and clinical care at Yale School of Medicine and Boston University School of Medicine/Boston Medical Center. The content of the policies was strongly influenced by the tenets of medical professionalism. Faculty support for new policies was strong, an iterative and inclusive process of formulation was critical, compromises in content were necessary, and the views of faculty concerning industry relationships were complex. After implementation of the new policies, the departmental food-related expenses increased, the loss of gifts was not appreciably missed, the faculty assumed more responsibility for educating trainees on the evaluation of new products, a central repository for receiving and evaluating grants from industry was useful, enforcement of the policies has been a lingering challenge, and the new policies generated positive publicity. Several recommendations are proposed. Creating these policies affirmed the importance of an inclusive process, open communication, support of institutional leadership, and focus on professional values.

    Lead is considered a highly toxic contaminant with important impacts to bird wildlife. Griffon vultures (Gyps fulvus) are a sensitive indicator of the level of environmental contamination due to their position at the top of the food chain and their dependence on human activities. The aim of this study was to assess susceptibility to lead intoxication in Griffon vultures admitted to Wildlife Rehabilitation Centers (WRC), measuring blood lead levels and determining if blood lead concentrations are related to clinical signs, hematological, biochemical or radiographic findings. Also, the influence of age, gender, body condition, season and primary cause of admission were evaluated. This study was realized in all Griffon vultures admitted during a period of one year in the Rehabilitation Center GREFA. Blood lead levels are measured by using anodic stripping voltammetry. In Griffon vultures, we observed that 26% of the analyzed birds presented lead levels above 20µg/dL with 74% below 20µg/dL ([Pb]<20 =9.34±5.60µg/dL). In our study, statistically significant differences were found for lead according to sex, season of admission to the center and body condition. A negative correlation was found between levels of metal and hematocrit. No association was found between clinical signs and blood lead levels in Griffon vultures, except for digestive signs as stasis and weight loss. On numerous occasions, the intoxication in this specie is related to ingestion of lead ammunition; however, we have not detected radiographic lead in our vultures. Compared with other studies, we generally found low levels of lead in blood of Griffon vultures but the blood of all birds admitted to WRC presented detectable lead concentrations. This species apparently presents a higher sensibility to the toxic effects of this metal than that described by other authors. It have been observed that there is some evidence that suggests that subclinical levels of lead could be related with a

    Concerns have been raised about the safety and efficacy of blood transfusions. Blood products are in demand and a decreasing supply is projected, with resource conservation a global concern. A consultant group determined that the transfusion rate at Mease Countryside Hospital was higher than an average baseline. A process-improvement project was initiated using a multidisciplinary team approach to improve blood utilization and ensure appropriateness in transfusion practice. The foundation of this project was to create new guidelines for transfusion; provide detailed education, communication, reporting, and feedback; and develop criteria to ensure compliance. The mean monthly usage of red blood cell units per 1000 inpatient discharges between April 2010 and October 2011 was 321.4 compared with 212.0 for the 5 months after implementation. The mean monthly number of patients transfused per 1000 inpatient discharges from April 2010 to October 2011 was 135.2 compared with 90.2 after implementation. In both cases, this reduction was found to be statistically significant at a 95% confidence level (P = 0.000 in both respects). The success of this project was the result of careful planning and execution, administrative support, physician leadership, and teamwork. Blood management includes strategies to avoid inappropriate transfusions and proactively treat anemia. Anemia management should be based on the patient's symptoms, laboratory values, and clinical assessment. Treatment of anemia should encompass a patient-centered approach, with the aim of promoting patient safety and minimizing the risk from exposure to blood products.

    2013-12-01

    South Africa (SA) faces a large unmet need for bone marrow (BM) transplantation, which could be alleviated in part by establishing a public umbilical cord blood stem cell bank (UCB SCB). Umbilical cord blood is an increasingly utilised source of hematopoietic stem cells for BM transplantation in addition to BM or mobilized peripheral blood stem cells. Establishing a public UCB SCB would therefore be a positive step towards improving the quality of health care in SA by providing for an important unmet need. This study takes the form of an enquiry into the acceptability of establishing a public bank through an interview with and questionnaire completed by mothers-to-be in the antenatal clinic of a large public hospital in SA. Initial results are positive, with 85 % of the participants in favour of establishing a public UCB SCB in SA. This initial probe will serve as a model for a more comprehensive national enquiry into public support and acceptability in different clinics, hospitals and provinces in SA.

    There are gaps in understanding the challenges with the establishment of pediatric cardiac surgical practices in Nigeria. The aim of this study was to examine the prospects and challenges limiting the establishment of pediatric cardiac surgical practices in Nigeria from the perspectives of cardiothoracic surgeons and resident doctors. A descriptive study was carried out to articulate the views of the cardiothoracic surgeons and cardiothoracic resident doctors in Nigeria. A self-administered questionnaire was used to generate information from the participants between December 2014 and January 2015. Data were analyzed using the SPSS version 21 statistical software package. Thirty-one of the 51 eligible participants (60.7%) took part in the survey. Twenty-one (67.7%) were specialists/consultants, and 10 (32.3%) were resident doctors in cardiothoracic surgical units. Most of the respondents, 26 (83.9%) acknowledged the enormity of pediatric patients with cardiac problems in Nigeria; however, nearly all such children were referred outside Nigeria for treatment. The dearth of pediatric cardiac surgical centers in Nigeria was attributed to weak health system, absence of skilled manpower, funds, and equipment. Although there was a general consensus on the need for the establishment of open pediatric cardiac surgical centers in the country, their set up mechanisms were not explicit. The obvious necessity and huge potentials for the establishment of pediatric cardiac centers in Nigeria cannot be overemphasized. Nevertheless, weakness of the national health system, including human resources remains a daunting challenge. Therefore, local and international partnerships and collaborations with country leadership are strongly advocated to pioneer this noble service. Copyright © 2016 Elsevier Inc. All rights reserved.

    Background When problems with compatibility beyond ABO and RhD arise, currently transfusion services search their inventories and perform time-consuming serologic testing to locate antigen-negative blood. These clinically important blood group antigens can be detected reliably by red cell genotyping, which is a technology whereby DNA-based techniques are used to evaluate gene polymorphisms that determine the expression of red cell antigens. We introduced mass-scale genotyping and measured availability of genotyped blood. Study design and methods All non-Caucasian donors qualified for genotyping along with Caucasian donors who had a history of repeat donation. Mass-scale red cell genotyping, performed on an electronic interfaced open array platform, was implemented to screen blood donors for 32 SNPs that predicted 42 blood group antigens. Genotype screening results were confirmed by phenotyping, when needed for antigen-negative transfusion, prior to release of the red cell unit. Results Approximately 22,000 donors were red cell genotyped within 4 months and a total of 43,066 donors in 4 years. There were 463 discordances (0.52% of 89,596 genotypes with a phenotype). Among the 307 resolved discordances, approximate equal numbers represented historical serological or genotyping discrepancies (n=151 and n=156, respectively). In the final year of the study, an average of 29% of the daily inventory had a genotype. Conclusions Red cell genotyping of blood donors using an electronic interface created a large and stable supply of red cell units with historical genotypes. The database served the needs of antigen-negative blood requests for a large regional blood center, and allowed us to abandon screening by serology. PMID:26094790

    Prior to human clinical trials, nonclinical safety and toxicology studies are required to demonstrate that a new product appears safe for human testing; these nonclinical studies are governed by good laboratory practice (GLP) regulations. As academic health centers (AHCs) embrace the charge to increase the translation of basic science research into clinical discoveries, researchers at these institutions increasingly will be conducting GLP-regulated nonclinical studies. Because the consequences for noncompliance are severe and many AHC researchers are unfamiliar with Food and Drug Administration regulations, the authors describe the regulatory requirements for conducting GLP research, including the strict documentation requirements, the necessary personnel training, the importance of study monitoring, and the critical role that compliance oversight plays in the process. They then explain the process that AHCs interested in conducting GLP studies should take before the start of their research program, including conducting a needs assessment and a gap analysis and selecting a model for GLP compliance. Finally, the authors identify and analyze several critical barriers to developing and implementing a GLP-compliant infrastructure at an AHC. Despite these challenges, the capacity to perform such research will help AHCs to build and maintain competitive research programs and to facilitate the successful translation of faculty-initiated research from nonclinical studies to first-in-human clinical trials.

    We describe the formulation and implementation of a participatory evaluation plan for three Transdisciplinary Collaborative Centers for Health Disparities Research funded by the National Institute of Minority Health and Health Disparities. Although different in scope of work, all three centers share a common goal of establishing sustainable centers in health disparities science in three priority areas - social determinants of health, men's health research, and health policy research. The logic model guides the process, impact, and outcome evaluation. Emphasis is placed on process evaluation in order to establish a "blue print" that can guide other efforts as well as assure that activities are being implemented as planned. We have learned three major lessons in this process: (1) Significant engagement, participation, and commitment of all involved is critical for the evaluation process; (2) Having a "roadmap" (logic model) and "directions" (evaluation worksheets) are instrumental in getting members from different backgrounds to follow the same path; and (3) Participation of the evaluator in the leadership and core meetings facilitates continuous feedback.

    Background Advances in the care of burn injuries have resulted from the efforts of regional patient-based specialist teams at burn care centers. Objectives We conducted this study to assess the four-year epidemiology of burn injuries in Rasht, Iran. Materials and Methods In this cross-sectional study, medical records of 2274 burn patients, treated at Velayat hospital from January 2007 to December 2010 in Rasht, Iran, were assessed. Age, sex, level of education, occupation, severity and degree of burn, burn surface area, burn cause and outcome of patients were evaluated. Results In our study the overall mortality rate was 8.7%; 65.7% of patients were men and 34.3% were women. Mean age of patients was 31.47 ± 22.67 years. Mean Total Burn Surface Area (TBSA) was 15.24 ± 18.4. Lowest TBSA was 0.5% and highest TBSA was 100%. Significant associations were observed between age (P = 0.0001), place of residence (P = 0.004), level of education (P = 0.0001), unemployment (P = 0.0001), marital status (P = 0.021), causes of burn (P = 0.0001), TBSA (P = 0.0001) and mortality rate. In our study, no significant difference was observed between age and sex (P = 0.071). Conclusions Due to high prevalence of burn injuries in Iran, increasing the level of awareness of the society as well as adhering to safety procedures both at home and workplace is recommended via implementing effective national safety policies.

    Child obesity is a major health problem particularly affecting disadvantaged population groups. Severe obesity carries additional health risks for children. In the context of the childhood obesity epidemic, high blood pressure among children is of increasing concern. Chart reviews were carried out to examine the prevalence of severe obesity and its association with high blood pressure measurements among randomly selected patients aged 3 to 17 years who had well-child care visits at 8 public community health centers during 2010. A majority of the 691 patients reviewed were African American (58%); an additional 16% were Hispanic. The prevalence of severe obesity was 7.7% (95% confidence interval = 5.8% to 9.9%) and the prevalence of high blood pressure measurements was 17.5% (95% confidence interval = 14.8% to 20.6%). Patients who were severely obese were more than twice as likely as other children to have high blood pressure values. Severe obesity is associated with substantially increased frequency of high blood pressure measurements in children, and should be investigated further as a potential marker for hypertension in children. Primary care providers should be prepared to diagnose and treat hypertension in severely obese children.

    A photochemical treatment (PCT) process has been developed to inactivate pathogens and white blood cells (WBCs) in therapeutic plasma. Process validation studies were performed in three European blood centers under routine operating conditions. Each center prepared 30 apheresis and 30 to 36 whole blood-derived plasma units for PCT. Each whole blood-derived plasma unit contained a mixture of two to three matched donations. After removal of pretreatment control samples (control fresh-frozen plasma [C-FFP]), 546 to 635 mL of plasma was treated with 15 mL of 6 mmol per L amotosalen, 3 J per cm(2) UVA treatment, and removal of residual amotosalen with a compound adsorption device. After processing, plasma samples (PCT-FFP) were withdrawn, frozen at -60 degrees C within 8 hours of collection, and assayed for coagulation factors and residual amotosalen. A total of 186 units of plasma were processed. The mean prothrombin time (12.2 +/- 0.6 sec) and activated partial thromboplastin time (32.1 +/- 3.2 sec) of PCT-FFP were slightly prolonged compared to C-FFP. Fibrinogen and Factor (F)VIII were most sensitive to PCT (26% mean reduction). PCT-FFP, however, retained sufficient levels of fibrinogen (217 +/- 43 mg/dL) and FVIII (97 +/- 29 IU/dL) for therapeutic plasma. Mean levels of FII, FV, FVII, F IX, FX, FXI, and FXIII in PCT-FFP were comparable to C-FFP (81%-97% retention of activity). Antithrombotic proteins were not significantly affected by PCT with retention ranging between 83 and 97 percent. Mean residual amotosalen levels were 0.6 +/- 0.1 micromol per L. Process validation studies in three European centers demonstrated retention of coagulation factors in PCT-FFP within the required European and respective national standards for therapeutic plasma.

    Large, complex computer systems require many years of development. It is recognized that large scale systems are unlikely to be delivered in useful condition unless users are intimately involved throughout the design process. A mechanism is described that will involve users in the design of advanced computing systems and will accelerate the insertion of new systems into scientific research. This mechanism is embodied in a facility called the Center for Advanced Architectures (CAA). CAA would be a division of RIACS (Research Institute for Advanced Computer Science) and would receive its technical direction from a Scientific Advisory Board established by RIACS. The CAA described here is a possible implementation of a center envisaged in a proposed cooperation between NASA and DARPA.

    Background: Confidential unit exclusion (CUE) system has been designed to enhance transfusion safety as an extra additive approach. Aims: This study was designed to survey demographic characteristics, prevalence of serologic markers, and reasons of opting CUE. Materials and Methods: The cross-sectional study was performed at Shiraz Blood Transfusion Center (Southern Iran). CUE is used for all individuals who refer for blood donation, and donors can choose their blood not to be used if they have any doubt about their blood suitability for transfusion. The prevalence rate of HIV, hepatitis B virus (HBV), and hepatitis C virus (HCV) was compared between the blood donors who opted into and out of CUE. Then, the donors were contacted to give another blood sample and the reasons of deferral. Researchers also determined whether their reasons were logical or not. Data were analyzed using comparison of proportions in MedCalc software 7. Results: Out of all the donors, 2365 ones (2.3%) opted for CUE. CUE was more frequent among men, singles, donors with low education levels, between 18 and 25 years old, and with history of previous donation (P < 0.05). The prevalence rate of HCV was higher among the donors who opted for CUE (P < 0.05), but it was not the case regarding HBV and HIV (P>0.05). Furthermore, 91.5% of the donors had opted for CUE by mistake and only 8% had chosen CUE logically. Conclusion: It is necessary to review the process of CUE, make some changes both in procedure and design, and then survey its effectiveness in blood safety. PMID:27605850

    Continuous improvement of efficiency as well as new expectations from customers (quality and safety of blood products) and employees (working conditions) imply constant efforts in Blood Transfusion Establishments (BTE) to improve work organisations. The Lean method (from "Lean" meaning "thin") aims at identifying wastages in the process (overproduction, waiting, over-processing, inventory, transport, motion) and then reducing them in establishing a mapping of value chain (Value Stream Mapping). It consists in determining the added value of each step of the process from a customer perspective. Lean also consists in standardizing operations while implicating and responsabilizing all collaborators. The name 5S comes from the first letter of five operations of a Japanese management technique: to clear, rank, keep clean, standardize, make durable. The 5S method leads to develop the team working inducing an evolution of the way in the management is performed. The Lean VSM method has been applied to blood processing (component laboratory) in the Pays de la Loire BTE. The Lean 5S method has been applied to blood processing, quality control, purchasing, warehouse, human resources and quality assurance in the Rhône-Alpes BTE. The experience returns from both BTE shows that these methods allowed improving: (1) the processes and working conditions from a quality perspective, (2) the staff satisfaction, (3) the efficiency. These experiences, implemented in two BTE for different processes, confirm the applicability and usefulness of these methods to improve working organisations in BTE.

    The Immediate Response Mobile Analyzer (IRMA) is a selective and portable point-of-care testing (POCT) blood gas, electrolyte and hematocrit (Hct) analyzer. The overall analytical performance was evaluated in a two-center study involving two Italian hospital laboratories, following the guidelines suggested by the manufacturer (based on the NCCLS protocol), after a preliminary evaluation of their formal validity. The IRMA was compared to the analyzers used in the routine laboratory as reference. The considered parameters were pH, pO2, pCO2, Na+, K+, ionized calcium and Hct. When using the aqueous quality control material provided by the manufacturer most of the parameters showed good precision, with the exception of pCO2 and pO2 that showed high CVs on two of the three levels of the aqueous control. We could demonstrate that this imprecision was material-related and was reduced when using a different material (blood equilibrated by tonometry). With tonometred blood for pO2 and pCO2 and the aqueous material for the remaining parameters the CVs were all below 5%, ranging from 0.08% to 2.8%. The IRMA results correlated adequately with the comparison instruments, with the exception of sodium and ionized calcium where contradictory results were obtained in the two centers.

    Some species of Cactaceae from the Sonoran Desert are characterized by a determinate growth pattern of the primary root, which is important for rapid lateral-root formation and seedling establishment. An analysis of the determinate root growth can be helpful for understanding the mechanism of meristem maintenance in plants in general. Stenocereus gummosus (Engelm.) Gibson & Horak and Pachycereus pringlei (S. Watson) Britton & Rose are characterized by an open type of root apical meristem. Immunohistochemical analysis of 5-bromo-2'-deoxyuridine incorporation into S. gummosus showed that the percentage of cells passing through the S-phase in a 24-h period is the same within the zone where a population of relatively slowly proliferating cells could be established and above this zone in the meristem. This indicated the absence of the quiescent center (QC) in S. gummosus. During the second and the third days of growth, in the distal meristem portion of P. pringlei roots, a compact group of cells that had a cell cycle longer than in the proximal meristem was found, indicating the presence of the QC. However, later in development, the QC could not be detected in this species. These data suggest that during post-germination the absence of the establishment of the QC within the apical meristem and limited proliferative activity of initial cells are the main components of a determinate developmental program and that establishment of the QC is required for maintenance of the meristem and indeterminate root growth in plants.

    The distribution of HLA-A, -B and -DR antigens as well as blood groups and secretor status was studied in sporadic, North Indian patients of rheumatic fever and rheumatic heart disease. While HLA-Aw33 occurred with an increased frequency in the patient group (X2 = 4.01), no statistically significant differences were observed in the frequency of B-locus antigens. In the DR locus, HLA-DR3 was found to be significantly increased (50% vs 26.1%, X2 = 13.8) and DR2 significantly reduced (21.8% vs 47.0%, X2 = 15.6). Also, there was a preponderance of non-'O' blood group individuals in the patient group as compared to controls. The DR3 association was significant only in those patients of RHD who did not have any previous history of rheumatic fever. These results indicate that susceptibility to rheumatic heart disease is HLA-class II mediated, with HLA-DR3 influencing susceptibility and DR2 conferring protection.

    A new approach to the analysis of the blood beryllium lymphocyte proliferation test (LPT) was presented to the Committee to Accredit Beryllium Sensitization Testing-Beryllium Industry Scientific Advisory Committee in April, 1994. Two new outlier resistant methods were proposed for the analysis of the blood LPT and compared with the approach then in use by most labs. The National Jewish Center (NJC) agreed to provide data from a study that was underway at that time. Three groups of LPT data are considered: (1) a sample of 168 beryllium exposed (BE) workers and 20 nonexposed (NE) persons; (2) 25 unacceptable LPTs, and (3) 32 abnormal LPTs for individuals known to have chronic beryllium disease (CBD). The LAV method described in ORNL-6818 was applied to each LPT. Graphical and numerical summaries similar to those presented for the ORISE data are given. Three methods were used to identify abnormal LPTs. All three methods correctly identified the 32 known CBD cases as abnormal.

    Pyelonephritides are frequently encountered diagnosis in Emergency Departments. Urinalyses have a central place in the management of this situation but the usefulness of blood cultures is not clear. We conducted a single-center retrospective study of 24 months to study the microbiological relevance of blood cultures in pyelonephritis. We included patients with blood cultures (BC) and urine cultures (UC) drawn at the same time, if they were not exposed to antibiotics prior to these tests. Of our 264 patients, 39 (15 %) had no bacteriological documentation. There were 83 (31 %) bacteremic patients. Seven patients had contaminated or sterile UC with positive BC. Four patients had positive UC and BC with the latter allowing identification of a pathogen absent from the UC (n = 1) or identifying the main pathogen in three cases. A total of 11 patients theoretically benefited from BC representing 4.2 % of our population. Excluding one patient who was known to be infected with multi-drug resistant bacteria, all empirical antibiotics regimens were effective against the identified pathogens. We did not reveal any significant therapeutic impact of blood cultures in the management of pyelonephritis, when BC and UC are performed before any antimicrobials treatment.

    To characterize the communication ritual in the pharmacist-customer dyad during a blood pressure measurement and counselling episode. A Portuguese urban community pharmacy. An exploratory, cross-sectional design was used. Participants were purposively selected and data collected via audio recording, as well as demographics and clinical information via questionnaire. Encounters' verbal content was transcribed verbatim, utterances identified, time stamped, and classified according to a coding scheme of fifteen categories. All data was statistically analyzed using SPSSv17. Four dialogue structures: speaker turn, interactivity, turn density and turn duration measurements. From a total of 51 participants, 72.5% were female with a median age of 66 years. The average systolic blood pressure was 140 mmHg, while the diastolic was 78 mmHg. The blood pressure measurement episode lasted for 5:35 min, with an average of 81 utterances. From all utterances registered, 55.3% were produced by the customer. Visits averaged 38 speaker turns, with an interactivity rate of approximately 7 turns per episode minute. For pharmacists, turn duration averaged 7.0 s and turn density 2.1 utterances. The customers' turns comprised a mean of 8.0 s, with 2.4 utterances. Longer episodes were related to more speaker turns and greater customer turn density and duration, but lower dialogue interactivity. The interactivity rate was also lower when the customers' utterances increased. Pharmacists asked more questions (essentially closed ones), while the customers gave more information. No significant associations were observed between elderly/non-elderly and gender in relation to all communication variables. However, an increased number of speaker turns and closed-questions were associated to a higher systolic pressure. It seems that pharmacists tend to control the content of the dialogue, while customers have more influence on the visit duration and interactivity. Specific hypertensive episodes induce

    At one blood center, each of 20 donors underwent plateletpheresis on four blood cell separators in random order. We compared the CS3000+, Amicus V 2.41, MCS Plus, and Spectra LRS V 7 Turbo regarding platelet (PLT) yield, pre- and post-procedure PLT counts, percent fall in donor PLT count, process time, efficiency, PLT product and donor PLT volume (MPV). Using >or= 150 x 10(9) PLTs/L pre-donation counts, a goal was set of 4.5 x 10(11) PLTs unit in up to 100 minutes processing time. Results were (mean values) PLT yields of Amicus, Spectra, CS3000+, and MCS Plus: 4.3, 4.6, 4.3, 4.0 x 10(11) PLTS, respectively; percent donor PLT fall: 24, 32, 30, 29%, respectively; processing times: 50, 74, 87, 101 minutes, respectively; relative efficiency (RE): 2.2, 1.6, 1.2,1.0, respectively (based on the MCS Plus performance with RE of 1 = 4 x 10(9) PLTS/min); PLT product MPV: 6.7, 7.4, 6.8,7.1 fL, respectively; pre-procedure donor MPV: 7.7, 7.3, 7.6 and 7.6 fL, respectively; and percent donor MPV change: -5.2, 0, -6.6, and -10%, respectively. Significant changes in the donor MPV were noted (P < 0.05) but could not be related to product MPV. Spectra seemed to collect larger PLTs (higher MPV); the significance remains unknown for both donors and recipients. Importantly, all four separators gave acceptable and comparable PLT yields (P < 0.05) with Spectra trending higher. The short process time and high RE together indicate highly efficient collections particularly by Amicus and Spectra.

    In December 1959 the Central Hospital for the Negev (today, the Soroka University Medical Center) opened its doors. This event was preceded by an arduous political battle over the Location of hospital facilities for inhabitants of Israel's south. On one side was the presiding Prime Minister David Ben-Gurion, who opposed the establishment of a hospital in Beer Sheba by the Clalit Sick Fund. On the other side were Beer Sheba's residents, led by David Tuviyahu--mayor of Beer Sheba, and Moshe Soroka--a member of the Clalit Sick Fund's management, who sought to bring about the immediate establishment of a hospital in the city itself, following the decision of the Hadassah Women's Organization to close the temporary hospital they had operated in Beer Sheba since 1948. The work at hand describes the ideological and political struggle between the two sides, the conflicting interests of the Government of Israel and the Labor Federation regarding the health needs of the city, and the factors that, in the end, led to the establishment of the hospital by the Federation's Clalit Sick Fund. The research is based on both archival material and on input from informants from the period who constitute primary sources.

    The Prader-Willi/Angelman imprinted domain on human chromosome 15q11-q13 is regulated by an imprinting control center (IC) composed of a sequence around the SNRPN promoter (PWS-SRO) and a sequence located 35 kb upstream (AS-SRO). We have previously hypothesized that the primary imprint is established on AS-SRO, which then confers imprinting on PWS-SRO. Here we examine this hypothesis using a transgene that includes both AS-SRO and PWS-SRO sequences and carries out the entire imprinting process. The epigenetic features of this transgene resemble those previously observed on the endogenous locus, thus allowing analyses in the gametes and early embryo. We demonstrate that the primary imprint is in fact established in the gametes, creating a differentially methylated CpG cluster (DMR) on AS-SRO, presumably by an adjacent de novo signal (DNS). The DMR and DNS bind specific proteins: an allele-discrimination protein (ADP) and a de novo methylation protein, respectively. ADP, being a maternal protein, is involved in both the establishment of DMR in the gametes and in its maintenance through implantation when methylation of PWS-SRO on the maternal allele takes place. Importantly, while the AS-SRO is required in the gametes to confer methylation on PWS-SRO, it is dispensable later in development.

We recently established criteria to evaluate the evidence for a causal association of a drug with TMA and then we systematically reviewed all published reports of drug-induced TMA (DITMA) to determine the level of evidence supporting a causal association of the suspected drug with TMA. On the basis of this experience, we used these evaluation criteria to assess the Oklahoma TTP-HUS Registry patients who had been previously categorized as drug-induced, 1989-2014. We also reviewed the experience of the BloodCenter of Wisconsin with testing for drug-dependent antibodies reactive with platelets and neutrophils in patients with suspected immune-mediated DITMA, 1988-2014. Among 58 patients in the Oklahoma Registry previously categorized as drug-induced (15 suspected drugs), 21 patients (three drugs: gemcitabine, pentostatin, quinine) had evidence supporting a definite association with TMA; 19 (90%) of the 21 patients had quinine-induced TMA. The BloodCenter of Wisconsin tested 40 patients with suspected DITMA (eight drugs); drug-dependent antibodies, supporting a definite association with TMA, were identified in 30 patients (three drugs: oxaliplatin, quinine, vancomycin); 28 (93%) of the 30 patients had quinine-induced TMA. Combining the data from these two sources, 51 patients (five drugs) have been identified with evidence supporting a definite association with TMA. DITMA was attributed to quinine in 47 (92%) of these 51 patients. © 2015 Wiley Periodicals, Inc.

    This paper presents a new initiative in the South-Eastern Health Region of Norway to establish a regional resource center focusing on services for children and adolescents aged 2–18 years with prenatal exposure to alcohol or other drugs. In Norway, the prevalence of fetal alcohol spectrum (FAS) is not known but has been estimated to be between 1 and 2 children per 1000 births, while the prevalence of prenatal exposure to illicit drugs is unknown. The resource center is the first of its kind in Scandinavia and will have three main objectives: (1) provide hospital staff, community health and child welfare personnel, and special educators with information, educational courses, and seminars focused on the identification, diagnosis, and treatment of children with a history of prenatal alcohol/drug exposure; (2) provide specialized health services, such as diagnostic services and intervention planning, for children referred from hospitals in the South-Eastern Health Region of Norway; and (3) initiate multicenter studies focusing on the diagnostic process and evaluation of interventions.

    Exposure of undergraduate medical students to general practice and community healthcare services is common practice in the international medical curricula. Nevertheless, proponents of the hospital and biotechnology based paradigm, which is still dominant within the medical academic environment, question both the scope and the setting of this training procedure. Regarding the latter, the quality of teaching is often questioned in settings such as rural primary health centers, where health professionals have neither incentives nor accredited training skills. Therefore, the success of community based medical education depends substantially on the procedures implemented to involve non-academic staff as clinical teachers. This report describes the steps taken by the Aristotle University of Thessaloniki (AUTH) Medical School to establish and maintain a Rural Primary Health Care (PHC) Teaching Network in order to implement community oriented PHC and GP undergraduate medical education. A multi-professional teachers' network of healthcare staff, working in Rural Primary Health Centers, has been chosen, in order to expose students to the holistic approach of PHC. The enrollment of teachers to the Teaching Network was solely on a voluntary basis. The novelty of this procedure is that each professional is approached personally, instead through the Health Center (HC) that usually offers this service as a package in similar activities. In an attempt to attract health professionals committed to medical education, a self-selection procedure was adopted. Collaboration with the medical school was established but it was characterized by the School's inability to compensate teachers. A series of 'Training the Trainers' seminars were completed during the first implementation period in order to enhance the awareness of health professionals regarding undergraduate teaching in PHC; to present the educational needs of medical students; to expose them to the principles of medical teaching

    When environmental analysis is performed, the high number of samples required and handling conditions during the transport of these samples to the laboratory are common problems. The comet assay is a useful, highly sensitive tool in biomonitoring. Some studies in the literature aim to preserve slides in lysis solution for use in the comet assay. Until now, however, no efficient methodology for preserving blood samples for this assay has been described. Because of this, the present report aimed to establish the proper conditions for samples maintenance prior to comet assay analysis. Samples were conserved in three different solutions: a high protein concentration solution (fetal bovine serum-FBS), an anticoagulant agent (a calcium chelator - ethylenediaminetetracetic acid - EDTA), and a salt buffered solution (phosphate buffered saline-PBS). Therefore, peripheral blood samples of Rhamdia quelen specimens were collected and maintained in these solutions until testing at 72h. Analyses of DNA fragmentation via the comet assay and cell viability via flow cytometry were performed at intervals of 24h. The results showed that samples maintained in FBS were preserved better; this was followed by those preserved in PBS and then last by those preserved in EDTA. In conclusion, blood samples from freshwater fish can be preserved up to 48h in fetal bovine serum at 4 degrees C in the absence of light. In this period, no DNA fragmentation occurs. We thus describe an excellent method of sample conservation for subsequent analysis in the laboratory.

    The effect of chronic voluntary exercise on resting blood pressure and heart rate was measured in two different age groups of spontaneously hypertensive rats (SHR). In the younger group, left ventricular dimensions were also measured. The younger group was 9 weeks old at the start of the experiment and was in a period of rapid blood-pressure rise. The older group, 13 weeks old at the start of the experiment, already had established hypertension. During a period of 6 weeks, the animals ran spontaneously in wheels mounted in their cages and reached a maximum of 6-7 km per 24 h. Age-matched, sedentary SHR were used as controls. Both groups of runners showed a decrease in body weight in comparison to controls. The younger runners exhibited a delayed onset of hypertension. They also showed a significantly increased left ventricular (LV) end-diastolic volume for every measured end-diastolic pressure between 7.5 mmHg and 20 mmHg (P less than 0.05). This suggests the development of a structural growth-dependent increase of the internal LV radius while LV weight and wall-to-lumen ratio were largely unaltered in younger runners compared with controls. In SHR with established hypertension, physical training did not reduce arterial blood pressure but heart rate was significantly lower than in the controls. These results thus indicate that an early onset of physical exercise in SHR may delay the development of hypertension. In addition, a more favourable cardiac design could also be seen.

  5. Benefits of Adding a Rapid PCR-Based Blood Culture Identification Panel to an Established Antimicrobial Stewardship Program

    Studies have demonstrated that the combination of antimicrobial stewardship programs (ASP) and rapid organism identification improves outcomes in bloodstream infections (BSI) but have not controlled for the incremental contribution of the individual components. Hospitalized adult patients with blood culture pathogens on a rapid, multiplex PCR-based blood culture identification panel (BCID) that included 19 bacterial species, 5 Candida spp., and 4 antimicrobial resistance genes were studied over sequential time periods in a pre-post quasiexperimental study in 3 groups in the following categories: conventional organism identification (controls), conventional organism identification with ASP (AS), and BCID with ASP (BCID). Clinical and economic outcomes were compared between groups. There were 783 patients with positive blood cultures; of those patients, 364 (115 control, 104 AS, and 145 BCID) met inclusion criteria. The time from blood culture collection to organism identification was shorter in the BCID group (17 h; P < 0.001) than in the control group (57 h) or the AS group (54 h). The BCID group had a shorter time to effective therapy (5 h; P < 0.001) than the control group (15 h) or AS group (13 h). The AS (57%) and BCID (52%) groups had higher rates of antimicrobial de-escalation than the control group (34%), with de-escalation occurring sooner in the BCID group (48 h; P = 0.034) than in the AS group (61 h) or the control group (63 h). No difference between the control group, AS group, and BCID group was seen with respect to mortality, 30-day readmission, intensive care unit length of stay (LOS), postculture LOS, or costs. In patients with BSI, ASP alone improved antimicrobial utilization. Addition of BCID to an established ASP shortened the time to effective therapy and further improved antimicrobial use compared to ASP alone, even in a setting of low antimicrobial resistance rates.

    Aim: Overall the risk of transfusion transmitted infections has decreased, especially viral infections like HIV and hepatitis B and C. Bacterial contamination of blood and its cellular components, however, remains a common microbiological cause of transfusion associated morbidity and mortality. Platelets pose a special risk given their preservation methods. The incidence of these episodes needs to be assessed and updated on regular basis to accurately manage the risk of transfusion transmitted bacterial infections. Method: 2,000 platelet samples from the Blood Transfusion Center of Isfahan were examined randomly during a 5-month period by bacterial culture and molecular tests. Four platelet samples were found to be contaminated with bacteria, giving a rate of contamination of 500 (0.2%) of tested platelets. Isolated bacteria included one each of Klebsiella pneumoniae, Staphylococcus aureus, Staphylococcus epidermidis and Staphylococcus haemolyticus. Conclusion: Our study underlines the need for additional safety procedures like bacterial screening and pathogen reduction technology to further decrease the risk of transfusion associated bacterial infections.

    Most common bacterial sepsis associated with transfusion is caused by contaminated Platelet Concentrates (PC). The screening of PC to detect bacterial contamination is obligatory in Mexico, and it is carried out in quality control programs. In Mexico, the identification and molecular characterization of bacterial contaminants to detect contamination sources have not been implemented due to high costs; however, it is an actual current need. One hundred PC were randomly selected and microbiologically analyzed. This sample size corresponds to 1% of the PC obtained by the National Center of Blood Transfusion (NCBT) in Mexico City according to the Official Mexican Standard NOM-253-SSA1-2012. Additionally, molecular biology tests were implemented in order to identify the possible contamination sources. Nine of the 100 PC analyzed (9%) showed bacterial contamination; analysis of the nucleotide sequences revealed the presence of characteristic microbiota from donor skin and soil. Diverse clonal relationship between the strains was identified in Staphylococcus epidermidis. Detection of contaminants associated with environmental and skin flora, shows the need to implement measures in the process of disinfecting skin at the site of phlebotomy and cleaning each of the areas involved in blood collection.

    BACKGROUND The wastage of red blood cell (RBC) units within the operative setting results in significant direct costs to health care organizations. Previous education-based efforts to reduce wastage were unsuccessful at our institution. We hypothesized that a quality and process improvement approach would result in sustained reductions in intraoperative RBC wastage in a large academic medical center. STUDY DESIGN AND METHODS Utilizing a failure mode and effects analysis supplemented with time and temperature data, key drivers of perioperative RBC wastage were identified and targeted for process improvement. RESULTS Multiple contributing factors, including improper storage and transport and lack of accurate, locally relevant RBC wastage event data were identified as significant contributors to ongoing intraoperative RBC unit wastage. Testing and implementation of improvements to the process of transport and storage of RBC units occurred in liver transplant and adult cardiac surgical areas due to their history of disproportionately high RBC wastage rates. Process interventions targeting local drivers of RBC wastage resulted in a significant reduction in RBC wastage (p <0.0001; adjusted odds ratio, 0.24; 95% confidence interval, 0.15–0.39), despite an increase in operative case volume over the period of the study. Studied process interventions were then introduced incrementally in the remainder of the perioperative areas. CONCLUSIONS These results show that a multidisciplinary team focused on the process of blood product ordering, transport, and storage was able to significantly reduce operative RBC wastage and its associated costs using quality and process improvement methods.

    Hypertension is a public health problem, considering its high prevalence, low control rate and cardiovascular complications. Evaluate the control of blood pressure (BP) and cardiovascular outcomes in patients enrolled at the Reference Center for Hypertension and Diabetes, located in a medium-sized city in the Midwest Region of Brazil. Population-based study comparing patients enrolled in the service at the time of their admission and after an average follow-up of five years. Participants were aged ≥ 18 years and were regularly monitored at the Center up to 6 months before data collection. We assessed demographic variables, BP, body mass index, risk factors, and cardiovascular outcomes. We studied 1,298 individuals, predominantly women (60.9%), and with mean age of 56.7 ± 13.1 years. Over time, there was a significant increase in physical inactivity, alcohol consumption, diabetes, dyslipidemia, and excessive weight. As for cardiovascular outcomes, we observed an increase in stroke and myocardial revascularization, and a lower frequency of chronic renal failure. During follow-up, there was significant improvement in the rate of BP control (from 29.6% to 39.6%; p = 0.001) and 72 deaths, 91.7% of which were due to cardiovascular diseases. Despite considerable improvements in the rate of BP control during follow-up, risk factors worsened and cardiovascular outcomes increased.

    Converting T cells into tumor cell killers by grafting them with a chimeric antigen receptor (CAR) has shown promise as a cancer immunotherapeutic. However, the inability of these cells to actively migrate and extravasate into tumor parenchyma has limited their effectiveness in vivo. Here we report the construction of a CAR containing an echistatin as its targeting moiety (eCAR). As echistatin has high binding affinity to αvβ3 integrin that is highly expressed on the surface of endothelial cells of tumor neovasculature, T cells engrafted with eCAR (T-eCAR) can efficiently lyse human umbilical vein endothelial cells and tumor cells that express αvβ3 integrin when tested in vitro. Systemic administration of T-eCAR led to extensive bleeding in tumor tissues with no evidence of damage to blood vessels in normal tissues. Destruction of tumor blood vessels by T-eCAR significantly inhibited the growth of established bulky tumors. Moreover, when T-eCAR was codelivered with nanoparticles in a strategically designed temporal order, it dramatically increased nanoparticle deposition in tumor tissues, pointing to the possibility that it may be used together with nanocarriers to increase their capability to selectively deliver antineoplastic drugs to tumor tissues.

  14. Implication of MEK1 and MEK2 in the establishment of the blood-placenta barrier during placentogenesis in mouse.

    The ERK/MAPK signalling cascade is involved in many cellular functions. In mice, the targeted ablation of genes coding for members of this pathway is often associated with embryonic death due to the abnormal development of the placenta. The placenta is essential for nutritional and gaseous exchanges between maternal and embryonic circulations, as well as for the elimination of metabolic waste. These exchanges occur without direct contact between the two circulations. In mice, the blood-placenta barrier consists of a triple layer of trophoblast cells adjacent to endothelial cells from the embryo. In the ERK/MAPK cascade, MEK1 and MEK2 are dual-specificity kinases responsible for the activation of the ERK1 and ERK2 kinases. Inactivation of Mek1 causes placental malformations resulting from defective proliferation and differentiation of the labyrinthine trophoblast cells and leading to a severe delay in the development and the vascularization of the placenta, which explains the embryonic death. Although Mek2(-/-) mutants survive without any apparent phenotype, a large proportion of Mek1(+/-)Mek2(+/-) double heterozygous mutants die during gestation from placenta anomalies affecting the establishment of the blood-placenta barrier. Together, these data reveal how crucial is the role of the ERK/MAPK pathway during the formation of the placenta. Copyright © 2012 Reproductive Healthcare Ltd. Published by Elsevier Ltd.

    The Wilms' tumour suppressor WT1 (Wilms' tumour 1) is a transcriptional regulator that plays a central role in organogenesis, and is mutated or aberrantly expressed in several childhood and adult malignancies. We previously identified BASP1 (brain acid-soluble protein 1) as a WT1 cofactor that suppresses the transcriptional activation function of WT1. In the present study we have analysed the dynamic between WT1 and BASP1 in the regulation of gene expression in myelogenous leukaemia K562 cells. Our findings reveal that BASP1 is a significant regulator of WT1 that is recruited to WT1-binding sites and suppresses WT1-mediated transcriptional activation at several WT1 target genes. We find that WT1 and BASP1 can divert the differentiation programme of K562 cells to a non-blood cell type following induction by the phorbol ester PMA. WT1 and BASP1 co-operate to induce the differentiation of K562 cells to a neuronal-like morphology that exhibits extensive arborization, and the expression of several genes involved in neurite outgrowth and synapse formation. Functional analysis revealed the relevance of the transcriptional reprogramming and morphological changes, in that the cells elicited a response to the neurotransmitter ATP. Taken together, the results of the present study reveal that WT1 and BASP1 can divert the lineage potential of an established blood cell line towards a cell with neuronal characteristics.

    The purpose of this report is to present the findings of a retrospective study (2008-2009) to determine the seroprevalence of hepatitis B and C virus in blood donors at the Blood Transfusion Center of Military Teaching Hospital Mohammed V in Rabat, Morocco. Samples from 19,801 consecutive blood donors were analyzed by the immuno-enzymatic method (Enzyme Linked Immunosorbent Assay, third generation). The overall seroprevalence of HBV and HCV was 0.8% and 0.2% respectively. A total of 98 units were rejected because of elevated alanine transaminase. No case of co-infection was found. From 1991 to 2010, HBV and HCV seropositivity showed a significant declining trend. In spite of the low prevalence observed, this study confirms that the risk of transfusion transmitted infection exists and thus underlines the need to implement preventive strategies to improve blood transfusion safety.

    Blood blister-like aneurysms (BBAs) are a controversial entity. They arise from non-branching sites on the supraclinoid internal carotid artery (ICA) and are suspected to originate from a dissection. Our aim is to describe the BBA cases seen in our center and to present a systematic review of the literature on BBAs. We analyzed the eleven cases of BBA admitted to our center from 2003 to 2012. We assessed the medical history, treatment modality (endovascular and/or surgery), complications and clinical outcome. The cohort included 8 women and 4 men with a mean age of 53.16 years. Treatment of the BBA consisted of stenting and coiling in 5 patients, stenting only in 4 patients, coiling and clipping in 1 patient, clipping only in 1 patient, and conservative treatment in 1 patient. A good outcome was found in 10 patients, as defined by a modified Rankin Scale (mRS) less than or equal to two at three months. A systematic review of the literature was performed, and 314 reported patients were found: 221 patients were treated with a primarily surgical approach, and 87 patients were treated with a primarily endovascular approach. A rescue or second treatment was required in 46 patients (21%). The overall estimated treatment morbidity rate was 17%, and the mortality rate was 15%. BBAs exhibit more aggressive behavior compared to saccular aneurysms, and more intra-operative complications occur with BBAs, independent of the treatment type offered. They are also significantly more likely to relapse and rebleed after treatment. Endovascular treatment offers a lower morbidity-mortality compared with surgical approaches. Multilayer flow-diverting stents appear to be a promising strategy.

    Background To evaluate the choice and utility of pacing maneuvers in the electrophysiology (EP) laboratory in establishing supraventricular tachycardia (SVT) mechanism. Methods We retrospectively examined a cohort of 160 consecutive patients with SVT presenting for invasive EP evaluation to a single center with 8 electrophysiologists. We analyzed the utility of the two most commonly used pacing maneuvers: (1) ventricular entrainment (VE) and (2) His-refractory premature ventricular stimuli (HRPVC) during SVT. Results VE was performed in 96 patients: atrial tachycardia (AT) 12, atrioventricular nodal reentrant tachycardia (AVNRT) 66, and orthodromic reciprocating tachycardia (ORT) 18. During VE, AT patients were most likely to have ventriculo-atrial (VA) dissociation (AT 58%, AVNRT 18%, ORT 0%, P < 0.001) and had a tendency towards less SVT termination (AT 0%, AVNRT 9%, ORT 11%, P = 0.19). HRPVCs were delivered in 39 patients: AT 1, AVNRT 24, and ORT 14. Advancement of atrial signal with HRPVC was only observed in ORT (AT 0%, AVNRT 0%, ORT 79%, P < 0.001) and SVT termination was also mostly observed in ORT (AT 0%, AVNRT 4%, ORT 21%, P = 0.33). The overall diagnostic utility of VE was lowest in AT (AT 42%, AVNRT 71%, ORT 83%, P = 0.04), while HRPVC was rarely used in AT. Furthermore, the utilization of maneuvers varied extensively (0% to100%) among the 8 electrophysiologists. Conclusion There is great variation in the utilization of pacing maneuvers and their utility in ascertaining the mechanism of SVT. Our results support the fact that discerning AT from AVNRT mechanism remains the most challenging task in SVT diagnosis. PMID:28357021

    MRI-targeted biopsy of the prostate appears to have the potential to reduce the high rates of underdiagnosis and overdiagnosis associated with the current diagnostic standard of transrectal ultrasound guided systematic biopsy. Direct or “in bore” MRI-guided biopsy is one of the three methods for MRI-targeted core needle sampling of suspicious, generally Pi-RADS 4 or 5, foci within the prostate, and our early experience suggests the approach demonstrates substantial utility and promise in the care of patients with prostate cancer. We performed direct MRI-guided biopsies in 50 patients within 19 months of establishing the first referral center for this service in our region. Our preliminary results indicate the service can be easily grown due to unmet demand, primarily in patients with a negative traditional systematic biopsy but with a concerning focus at MRI (30 of 50; 60%). Other applications include evaluation of patients who are on active surveillance (n=14; ten upgraded to higher Gleason score at MRI-guided biopsy), who are biopsy naïve (n=5; all positive at MRI-guided biopsy), or post focal therapy (n=1; positive for recurrent tumor at MRI-guided biopsy). With careful patient selection and technique, we have achieved a favorable overall positive biopsy rate of 73% (37 of 50), with 84% (31 of 37) positive biopsies demonstrating Gleason score 7 or greater disease. Large multicenter comparative trials will be required to determine the relative accuracy and appropriate utilization of direct MRI guided biopsy in the care pathway of patients with known or suspected prostate cancer.

    Elevated blood pressure is a major risk factor for cardiovascular disease and stroke but patients often discount recommended behavioral changes and prescribed medications. While effective interventions to promote adherence have been developed, cost-effectiveness from the patient's perspective, has not been well studied. The valuation of patient time and out of pocket expenses should be included while performing cost effectiveness evaluation. The Achieve BP study uses the contingent valuation method to assess willingness to accept (WTA) and willingness to pay (WTP) among patients with a history of uncontrolled blood pressure discharged from an urban emergency department and enrolled in a larger randomized controlled trial. WTA and WTP were assessed by asking patients a series of questions about time and travel costs and time value related to their study participation. A survey was conducted during the final study visit with patients to investigate the effectiveness of a kiosk-based educational intervention on blood pressure control. All study patients, regardless of study arm, received the same clinical protocol of commonly prescribed antihypertensive medication and met with research clinicians four times as part of the study procedures. Thirty-eight patients were offered the opportunity to participate in the cost-effectiveness study and all completed the survey. Statistical comparisons revealed these 38 patients were similar in representation to the entire RCT study population. All 38 (100.0%) were African-American, with an average age of 49.1 years; 55.3% were male, 21.1% were married, 78.9% had a high school or higher education, and 44.7% were working. 55.9% did not have a primary care provider and 50.0% did not have health insurance. Time price linear regression analysis was performed to estimate predictors of WTA and WTP. WTP and WTA may generate different results, and the elasticities were proportional to the estimated coefficients, with WTP about twice as

    In sub-Saharan Africa, most collected blood originates from accessible and cheaper replacement donors while recruiting and retaining volunteers requires considerable costs not all countries can afford. The Kumasi Teaching Hospital Blood Center and a local FM radio station developed a partnership calling three times a year for donation at the radio station where music, entertainment, and token gifts were available. To assess the program's impact, attendance, deferral, age, sex, identification, and viral test results of donors attending 12 consecutive sessions in 2003 through 2006 were analyzed, and this donor population was compared to other types of donors in Kumasi, Ghana. A total of 3801 donors attended the program and 92 percent of the potential FM donors were eligible to donate compared to 85.5 and 70.3 percent of other volunteer and replacement donors, respectively. Ninety percent of donors were male (median, 25 years) and 4.9 percent were hepatitis B surface antigen-positive compared to 11 and 15 percent in other volunteer and replacement donors. This reflected 63.6 percent spontaneous repeat donations from donors responding to the radio appeal compared to 15 to 30 percent in other volunteer donors. It has been demonstrated that the use of a culturally and socially adapted environment to make the gift of blood a pleasurable and festive experience generated a new pool of blood donors spontaneously repeating donations. This program indicates that retaining Ghanaian blood donors is possible at little extra cost to the blood center and that such an approach may represent a substantial help in the efforts of sub-Saharan Africa to collect volunteer blood.

    There is a large unmet need in South Africa for bone marrow transplantation. Umbilical cord blood (UCB) is an important source of stem cells for the treatment of haematological and non-haematological diseases. Access to the two existing private umbilical cord blood stem cell banks (UCB SCBs) in South Africa is limited to individuals that can afford it, which further aggravates the ever increasing divide between families from different socio-economic classes. The problem is compounded by a severe global shortage of genetically compatible samples, representative of the South African demographics. Establishing a public human UCB SCB in South Africa would provide more South Africans with access to previously unavailable treatment in the form of affordable, genetically compatible stem cells for bone marrow transplantation. A public UCB SCB has many facets to consider, one of which is public preparedness and support for the bank. This was assessed in a social feasibility pilot study which is reported here. In addition to the findings of this social feasibility study, other important considerations for establishing a public human UCB SCB in SA include; (a) testing the samples for HIV and other infectious diseases (required for compliance with international regulatory standards); (b) flow cytometric analysis for enumeration of CD34+ UCB stem cells; (c) mapping of HLA genotypes/alleles; and (d) a study of the economic feasibility of this endeavour.The social feasibility study was conducted to gauge public preparedness and support for a public SCB through patient interviews and questionnaires. The process was dynamic due to its novel nature for interviewers and interviewees alike. Many obstacles were met and dealt with which lead to the compilation of results discussed here in the form of a pilot social feasibility study.In the South African context, we are faced with unique and rich challenges relating to cultural and religious differences that are further augmented by

    Zinc protoporphyrin (ZPP) values were analyzed with a hematofluorometer on 395 non-occupationally lead exposed subjects. Blood lead (B-Pb) determinations were concurrently carried out with an extraction procedure using flameless atomic absorption method. Applying Hoffman's Statistical Analysis with a logarithmic transformation, a normal range for ZPP (a mean of 23 microgram/dL) was established with 40 microgram ZPP/dL on the upper limit of the 95% probability range. A value of 54 microgram ZPP/dL has been found to be a suitable cutoff value above which one generally finds B-Pb values greater than 40 microgram/dL. For B-Pb values (less than 40 microgram/dL) and ZPP values in our normal range, there was essentially no correlation. However, for elevated values of both, a correlation coefficient of 0.87 was found for log ZZP versus B-Pb. ZPP values for males appeared to increase with increasing age.

    This study aims to determine the prevalence of human immunodeficiency virus (HIV) infections and hepatitis B virus (HBV) and hepatitis C virus (HCV) infections among blood donors at the Blood Donor Center, Mohammed V Military Teaching Hospital between 2010 and 2012. We conducted a retrospective study among military blood donors aged 18-50 years, with a male predominance (95%). Pre-donation interview is the first selection barrier for individuals at risk. Biological screening was performed by liquid enzyme immunoassay technique using antibodies and/or antigen. Fourth generation combined HCV and HIV antigen/antibody ELISA (enzyme-linked immunosorbent assay) test was used. The Blood Donor Center and the laboratory of virology used the same technique performed in duplicate to confirm results. Out of 25661 tested samples, the prevalence rate of HBV infections was 3.97 ‰ (n = 102), the prevalence rate of HCV infections was 2.45 ‰ (n = 63) and the prevalence rate of HIV infections was 0.15 ‰ (n = 4). A single case with HBV and HCV virus co-infection (0.039 ‰) was registered, no association between HIV-HBV, HIV-HCV or HBV, HCV and HIV infections was recorded. The low seroprevalence rates of viral markers recorded in our study show improvement in preventive measures for donor selection and screening tests. The registered prevalence encourages the use of combined reagent, which is the only alternative to molecular biology in developing countries.

    Controlled-rate freezing (CRF) followed by storage in liquid nitrogen is employed by most centers as the standard procedure for peripheral blood progenitor cell (PBPC) cryopreservation. Uncontrolled-rate freezing (URF) at -80 degrees C is more simple, time-saving, less expensive, and, possibly, as effective as CRF. The aim of this retrospective analysis was to compare CRF and URF in childhood transplantation. A total of 54 PBPC transplants performed in 39 children aged 3 to 16 years (median, 9.5 years) were analyzed: 23 transplants in 16 children with CRF versus 31 transplants performed in 23 children with -80 degrees C URF. All grafts contained at least 2 x 10(6) per kg unselected CD34+ cells, enumerated before freezing. Nucleated cells infused ranged from 1.32 x 10(8) to 4.3 x 10(8) per mL with a median of 3.1 x 10(8) per mL. Cryoprotectant solution consisted of a final dimethyl sulfoxide (DMSO) concentration of 10 percent DMSO with autologous plasma. The two study groups did not differ in terms of timing of neutrophil and platelet recovery or transfusion requirements. Adverse events related to graft infusion, severe complications, and transplant-related mortality were not significantly different between CRF and URF groups. In both groups only mild adverse events were observed during graft administration. URF procedures, however, were simpler and less expensive. At a median follow-up of 72 months, no secondary myelodysplasia was observed in either group. Our analysis suggests that URF is safe and effective in the pediatric population.

    During the past decade, the hand-in-hand development of biotechnology and bioinformatics has enabled a view of the function of the red blood cell that surpasses the supply of oxygen and removal of carbon dioxide. Comparative proteomic inventories have yielded new clues to the processes that regulate membrane–cytoskeleton interactions in health and disease, and to the ways by which red blood cells communicate with their environment. In addition, proteomic data have revealed the possibility that many, hitherto unsuspected, metabolic processes are active in the red blood cell cytoplasm. Recent metabolomic studies have confirmed and expanded this notion. Taken together, the presently available data point towards the red blood cell membrane as the hub at which all regulatory processes come together. Thus, alterations in the association of regulatory proteins with the cell membrane may be a sine qua non for the functional relevance of any postulated molecular mechanism. From this perspective, comparative proteomics centered on the red blood cell membrane constitute a powerful tool for the identification and elucidation of the physiologically and pathologically relevant pathways that regulate red blood cell homeostasis. Additionally, this perspective provides a focus for the interpretation of metabolomic studies, especially in the development of biomarkers in the blood. PMID:28248245

    The concentration of chromium in the blood (CrB) has been confirmed as a biomarker for occupational chromium exposure, but its biological exposure indices (BEIs) are still unclear, so we collected data from the years 2006 and 2008 (Shandong Province, China) to analyze the relationship between the concentration of chromium in the air (CrA) of the workplaces and CrB to establish a reference value of CrB for biological monitoring of occupational workers. The levels of the indicators for nasal injury, kidney (β2 microglobulin (β2-MG)), and genetic damages (8-hydroxy-deoxyguanosine (8-OHdG) and micronucleus (MN)) were measured in all subjects of the year 2011 (Henan Province, China) to verify the protective effect in this reference value of CrB. Compared with the control groups, the concentrations of CrA and CrB in chromium exposed groups were significantly higher (P < 0.05). Positive correlations were found between CrA and CrB in chromium exposed groups (r 2006 = 0.60, r 2008 = 0.35) in the years 2006 and 2008. According to the occupational exposure limitation of CrA (50 μg/m(3), China), the reference value of CrB was recommended to 20 μg/L. The levels of nasal injury, β2-MG, 8-OhdG, and MN were not significantly different between the low chromium exposed group (CrB ≤ 20 μg/L) and the control group, while the levels of β2-MG, 8-OHdG, and MN were statistically different in the high chromium exposed group than that in the control group. This research proved that only in occupational workers, CrB could be used as a biomarker to show chromium exposure in the environment. The recommended reference value of CrB was 20 μg/L. © The Author(s) 2015.

    Bartonella henselae is an emerging infectious agent that mainly causes cat scratch disease, basillary angiomatosis and peliosis hepatitis. Although many basillary angiomatosis cases have been reported especially from the Mediterranean region of Turkey, adequate data about the seroprevalence of B. henselae in Turkey does not exist. The aim of this study was to investigate the seroprevalence of B. henselae in volunteer blood donors and the related risk factors. In this study, sera samples were randomly collected from 800 (771 man, 29 women; age range: 18-60 years) voluntary healthy blood donors admitted to Pamukkale University Research and Training Hospital. B. henselae (Houston-1 strain) total antibodies were investigated by an in-house indirect immunofluorescent antibody assay. Seropositivity was detected in 6% (48/800) of the donors. B. henselae (Houston-1) antibody titer was 1/64 in 40 of the donors, 1/128 in 4, 1/256 in 2, 1/512 in 1 and 1/1024 in 1 of the donors. Statistical analysis of epidemiological and demographical data revealed that high seroprevalence rates have been found in rabbit stockfarmers (p = 0.004), students staying at hostels (p = 0.04) and people with history of tick-bite (p = 0.03). No significant statistical differences were found in each related groups in terms of age, sex, chronic disorders, sport activities, outside behaviors, being injured by any wild or domestic animals, working outdoors, geographical properties of the area of inhabitance, hunting and travelling (p > 0.05). One of the high titer (1/512) antibody positive subjects was a cat owner and had a history of phlebotomus bite, pediculosis and sporting in open area while 1/1024 titer positive case was a farmer and a dog owner. Our healthy blood donors' seroprevalence results are similar to those of other Mediterranean countries. The analysis of epidemiological data revealed that tick bite history and rabbit stockfarming were the risk factors for B. henselae infection. Variability

In the face of institutionally imposed practice change prohibiting obtaining blood cultures from intravenous (i.v.) catheters in the ED, our aim of was to compare the rate of contaminated blood cultures between those taken from recently placed i.v. catheters and those taken by direct venepuncture. Prospective, non-randomised, observational study comparing the rate of contaminated blood cultures for specimens taken from recently placed (<1 h) i.v. catheters and direct venepuncture in adult ED patients. Outcome of interest was the rate of false positive cultures. Analysis was by comparison of proportions (χ(2) -test). Four hundred seventy-two blood culture sets were studied. There were 65 positive cultures, of which 49 (75%; 95% confidence interval [CI], 63-85%) were classified as true positive. The overall rate of contaminated blood cultures was 3.4% (95% CI, 2.0-5.6%). There was no difference in false positive rate between blood cultures taken via venepuncture and those taken from a recently placed i.v. cannula (P = 0.52; odds ratio, 0.9; 95% CI, 0.33-2.44). We found no difference in contaminated blood culture rate between recently placed i.v. catheters and direct venepuncture when infection control procedures were followed. © 2013 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.

    Insight into motivating factors and barriers for blood donation, especially for young people and underrepresented minorities, is important to donor recruitment and retention. We surveyed donors at a new blood collection facility based on a large, ethnically diverse university campus. Individuals who had donated or attempted to donate at the facility during the first 17 months of its operation were invited by e-mail to respond to an anonymous, Web-based questionnaire. Respondents were asked to provide demographic characteristics, rate the importance of various motivating and deterring factors for blood donation, and indicate how they prefer to be contacted by the blood center. More than 30% of the 1619 invitees responded, 95.6% (n = 479) of whom gave complete responses. The respondents were ethnically diverse, and 79.1% were between 18 and 28 years of age. Altruism was by far the most important motivating factor for donation. However, incentives were also rated as important or very important by 72.2% of the respondents. Inconvenience due to time or location constraints was the most important deterrent. E-mailing was the most preferred contact method and chosen by 80.3% of those surveyed. Some differences were noted in the responses from members of different age, sex, and ethnic groups. Although overall altruism and inconvenience were the major motivating factor and deterrent for blood, some demographic differences existed in donor attitude toward incentive programs and preference for the method of contact used by blood centers for recruitment purposes. © 2011 American Association of Blood Banks.

  2. The design and rationale of a multi-center clinical trial comparing two strategies for control of systolic blood pressure: The Systolic Blood Pressure Intervention Trial (SPRINT)

    PubMed Central

    2014-01-01

    Background High blood pressure is an important public health concern because it is highly prevalent and a risk factor for adverse health outcomes, including coronary heart disease, stroke, decompensated heart failure, chronic kidney disease, and decline in cognitive function. Observational studies show a progressive increase in risk associated with blood pressure above 115/75 mm Hg. Prior research has shown that reducing elevated systolic blood pressure lowers the risk of subsequent clinical complications from cardiovascular disease. However, the optimal systolic blood pressure to reduce blood pressure-related adverse outcomes is unclear, and the benefit of treating to a level of systolic blood pressure well below 140 mm Hg has not been proven in a large, definitive clinical trial. Purpose To describe the design considerations of the Systolic Blood Pressure Intervention Trial (SPRINT) and the baseline characteristics of trial participants. Methods SPRINT is a multi-center, randomized, controlled trial that compares two strategies for treating systolic blood pressure: one targets the standard target of <140 mm Hg, and the other targets a more intensive target of <120 mm Hg. Enrollment focused on volunteers of age ≥50 years (no upper limit) with an average baseline systolic blood pressure ≥130 mm Hg and evidence of cardiovascular disease, chronic kidney disease, 10-year Framingham cardiovascular disease risk score ≥15%, or age ≥75 years. SPRINT recruitment also targeted three pre-specified subgroups: participants with chronic kidney disease (estimated glomerular filtration rate <60 ml/min/1.73m2), participants with a history of cardiovascular disease, and participants 75 years of age or older. The primary outcome is first occurrence of a myocardial infarction, acute coronary syndrome, stroke, heart failure, or cardiovascular disease death. Secondary outcomes include all-cause mortality, decline in kidney function or development of end-stage renal disease

    BACKGROUND: Blood transfusion plays vital roles in the medical and surgical practice. To achieve optimum use of blood, transfusion has to be appropriate and judicious consuming minimal resources and manpower. OBJECTIVE: To evaluate the pattern of blood transfusion requests and utilization with the aim of determining transfusion practice. MATERIALS AND METHODS: Blood request forms and cross-match worksheets at the blood bank were analyzed over a 6-month period. Numbers of requisitions, blood units cross-matched, issued out, transfused, and nontransfused were calculated. Nonusage probability (NUP) and the cross-match to transfusion ratio (CTR) for each clinical unit were computed. RESULTS: Two thousand two hundred and sixty-eight units of blood were cross-matched for 1487 patient's transfusion requests, out of which only 1455 (64.2%) were transfused giving a total CTR of 1.6 for the hospital. The CTR for the various clinical units were: Obstetrics and gynecology (O and G) 2.7, surgery 2.1, orthopedics 1.9, medicine 1.1, pediatrics 1, and oncology 1. CONCLUSIONS: The overall CTR (1.6) of the hospital was within the optimal range except for the O and G and surgery department which were having very high NUP and CTR indicating their suboptimal transfusion practices. Introducing revised transfusion guidelines, maximum surgical blood ordering schedule and type, screen, save, and abbreviated cross-match method can help toward adequate requisition and utilization of blood thereby reducing wastage of resources, time, and manpower.

    Background: Hypertension is a public health problem, considering its high prevalence, low control rate and cardiovascular complications. Objective: Evaluate the control of blood pressure (BP) and cardiovascular outcomes in patients enrolled at the Reference Center for Hypertension and Diabetes, located in a medium-sized city in the Midwest Region of Brazil. Methods: Population-based study comparing patients enrolled in the service at the time of their admission and after an average follow-up of five years. Participants were aged ≥18 years and were regularly monitored at the Center up to 6 months before data collection. We assessed demographic variables, BP, body mass index, risk factors, and cardiovascular outcomes. Results: We studied 1,298 individuals, predominantly women (60.9%), and with mean age of 56.7±13.1 years. Over time, there was a significant increase in physical inactivity, alcohol consumption, diabetes, dyslipidemia, and excessive weight. As for cardiovascular outcomes, we observed an increase in stroke and myocardial revascularization, and a lower frequency of chronic renal failure. During follow-up, there was significant improvement in the rate of BP control (from 29.6% to 39.6%; p = 0.001) and 72 deaths, 91.7% of which were due to cardiovascular diseases. Conclusion: Despite considerable improvements in the rate of BP control during follow-up, risk factors worsened and cardiovascular outcomes increased.Fundamento: A hipertensão arterial é um problema de saúde pública devido à sua elevada prevalência, baixa taxa de controle e complicações cardiovasculares.

    Objective Deferral of blood donors due to low hematocrit and iron depletion is commonly reported in blood banks worldwide. This study evaluated the risk factors for low hematocrit and iron depletion among prospective blood donors in a large Brazilian blood center. Method A case–control study of 400 deferred donors due to low hematocrit and 456 eligible whole blood donors was conducted between 2009 and 2011. Participants were interviewed about selected risk factors for anemia, and additional laboratory tests, including serum ferritin, were performed. Bivariate and multivariate analyses were performed to assess the association between predictors and deferral due to low hematocrit in the studied population and iron depletion in women. Results Donors taking aspirins or iron supplementation, those who reported stomachache, black tarry stools or hematochezia, and women having more than one menstrual period/month were more likely to be deferred. Risk factors for iron depletion were repeat donation and being deferred at the hematocrit screening. Smoking and lack of menstruation were protective against iron depletion. Conclusion This study found some unusual risk factors related to gastrointestinal losses that were associated with deferral of donors due to low hematocrit. Knowledge of the risk factors can help blood banks design algorithms to improve donor notification and referral. PMID:26408364

    Apixaban (Eliquis™) was developed by Bristol-Myers Squibb (BMS) and Pfizer to use as an antithrombotic/anticoagulant agent and has been recently approved for the prevention of stroke and systemic embolism in patients with nonvalvular atrial fibrillation. A clinical study of apixaban, sponsored by BMS and Pfizer, included a pilot exploratory portion to evaluate the potential for future drug concentration monitoring using dried blood spot (DBS) sample collection. For DBS sample collection, a fixed blood volume was dispensed onto a DBS card by either regular volumetric pipette (venous blood collection) or capillary dispenser (finger prick blood collection). A 96-well semi-automated liquid-liquid extraction sample preparation procedure was developed to provide clean extracts for UHPLC-MS/MS quantitation. Assays using both partial-spot center punch and whole spot punch were developed and validated. The linear dynamic ranges for all the analyses were from 0.5 to 500 ng/mL. The coefficient of determination (r(2)) values was >0.9944 for all the validation runs. For the center punch approach, the intra-assay precision (%CV) was within 4.4% and inter-assay precision was within 2.6%. The assay accuracy, expressed as %Dev., was within ± 5.4% of the nominal concentrations. One accuracy and precision run was performed using the whole spot approach, the intra-assay precision (%CV) was within 7.1% and the accuracy was within ± 8.0% of the nominal concentrations. In contrast to the center punch approach, the whole spot approach eliminated the effect of hematocrit and high lipids on the analysis of apixaban in human DBS when an accurate sample blood volume was collected on DBS cards.

    The study was conducted to emphasize the sensitivity and specificity of dental pulp in identifying the ABO Blood group, Rhesus factor and also to emphasize the role of dental pulp in forensic odontology to identify the deceased individual. The study was conducted on 60 patients. The samples obtained from finger-prick method from those 60 patients were considered as control and the samples obtained from the pulp were considered as case. The blood grouping, Rhesus typing for capillary blood drawn by finger prick was done by slide-agglutination method and the blood grouping, Rhesus typing for extracted dental pulp was done by absorption-elution method. Fifty seven teeth out of sixty showed positive results. Blood group elicited from capillary blood done by slide-agglutination method matched with that of the pulpal blood group elicited by absorption-elution method. Three showed negative results. As the teeth are the hardest, most stable biological material, resist adverse environmental conditions and the pulpal tissue inside the teeth is well protected, the blood group antigen from pulp remains stable for long. Thus, the high potential value of dental pulp tissue is highlighted in this study.

    The formation and certification of Primary Stroke Centers has progressed rapidly since the Brain Attack Coalition's original recommendations in 2000. The purpose of this article is to revise and update our recommendations for Primary Stroke Centers to reflect the latest data and experience. We conducted a literature review using MEDLINE and PubMed from March 2000 to January 2011. The review focused on studies that were relevant for acute stroke diagnosis, treatment, and care. Original references as well as meta-analyses and other care guidelines were also reviewed and included if found to be valid and relevant. Levels of evidence were added to reflect current guideline development practices. Based on the literature review and experience at Primary Stroke Centers, the importance of some elements has been further strengthened, and several new areas have been added. These include (1) the importance of acute stroke teams; (2) the importance of Stroke Units with telemetry monitoring; (3) performance of brain imaging with MRI and diffusion-weighted sequences; (4) assessment of cerebral vasculature with MR angiography or CT angiography; (5) cardiac imaging; (6) early initiation of rehabilitation therapies; and (7) certification by an independent body, including a site visit and disease performance measures. Based on the evidence, several elements of Primary Stroke Centers are particularly important for improving the care of patients with an acute stroke. Additional elements focus on imaging of the brain, the cerebral vasculature, and the heart. These new elements may improve the care and outcomes for patients with stroke cared for at a Primary Stroke Center.

    Patient-derived tumor xenografts (PDTX) generally represent a kind of more reliable model of human disease, by which a potential drugs’ preclinical efficacy could be evaluated. To date, no stable gastrointestinal stromal tumor (GIST) PDTX models have been reported. In this study, we aimed to establish stable GIST PDTX models and to evaluate whether these models accurately reflected the histological feature of the corresponding patient tumors and create a reliable GIST PDTX models for our future experiment. By engrafting fresh patient GIST tissues into immune-compromised mice (BALB/c athymic mice), 4 PDTX models were established. Histological features were assessed by a qualified pathologist based on H&E staining, CD117 and DOG-1. We also conduct whole exome sequencing(WES) for the 4 established GIST PDTX models to test if the model still harbored the same mutation detected in corresponding patient tumors and get a more intensive vision for the genetic profile of the models we have established, which will help a lot for our future experiment. To explore the tumorigenesis mechanism for GIST, we also have a statistical analysis for the genes detected as nonsynchronous-mutated simultaneously in 4 samples. All 4 GIST PDTX models retained the histological features of the corresponding human tumors, with original morphology type and positive stains for CD117 and DOG-1. Between the GIST PDTX models and their parental tumors, a same mutation site was detected, which confirmed the genetic consistency. The stability of molecular profiles observed within the GIST PDTX models provides confidence in the utility and translational significance of these models for in vivo testing of personalized therapies. To date, we conducted the first study to successfully establish a GIST PDTX model whose genetic profiles were revealed by whole exome sequencing. Our experience could be of great use. PMID:27186422

    Allogeneic stem cell transplantation (SCT) is the most effective treatment option for many hematologic malignancies, but graft-versus-host disease (GVHD) remains a major cause of treatment failure. Along with well-established risk factors for transplantation outcomes, recent single-center studies have identified a birth order effect in HLA-identical sibling SCT, with lower rates of acute and chronic GVHD and improved overall survival when the donor is younger than the recipient. One hypothesized mechanism for this effect is microchimerism due to fetomaternal and transmaternal sibling cell trafficking during pregnancy as the donor is exposed to recipient antigens in utero. The aim of the present study was to validate previously reported single-center data in a large, multicenter cohort provided by the Center for International Blood and Marrow Transplantation. All adult and pediatric patients (n = 11,365) with a hematologic malignancy who underwent allogeneic SCT with a graft from an HLA-identical sibling donor between 1990 and 2007 were included. When donors were younger than recipients, there was a significantly lower rate of acute GVHD grade II-IV and chronic GVHD in children, as well as a lower rate of chronic GVHD in adolescents. However, the hypothesized overall positive effect of lower relapse and better survival when donors are younger than recipients was not observed. Our data suggest that if otherwise equally matched, a graft from a younger sibling may be superior to a graft from an older sibling for children and adolescents undergoing SCT.

    Background Tubercular lymphadenitis (TL) is the most common form of extra-pulmonary tuberculosis (TB) consisting about 15–20% of all TB cases. The currently available diagnostic modalities for (TL), are invasive and involve a high index of suspicion, having limited accuracy. We hypothesized that TL would have a distinct cytokine signature that would distinguish it from pulmonary TB (PTB), peripheral tubercular lymphadenopathy (LNTB), healthy controls (HC), other lymphadenopathies (LAP) and cancerous LAP. To assess this twelve cytokines (Tumor Necrosis Factor (TNF)—α, Interferon (IFN) -γ, Interleukin (IL)-2, IL-12, IL-18, IL-1β, IL-10, IL-6, IL-4, IL-1Receptor antagonist (IL-1Ra), IL-8 and TNF-β, which have a role in pathogenesis of tuberculosis, were tested as potential peripheral blood biomarkers to aid the diagnosis of TL when routine investigations prove to be of limited value. Methods and Findings A prospective observational cohort study carried out during 2010–2013. This was a multi-center study with three participating hospitals in Delhi, India where through random sampling cohorts were established. The subjects were above 15 years of age, HIV-negative with no predisposing ailments to TB (n = 338). The discovery cohort (n = 218) had LNTB (n = 50), PTB (n = 84) and HC (n = 84). The independent validation cohort (n = 120) composed of patients with cancerous LAP (n = 35), other LAP (n = 20) as well as with independent PTB (n = 30), LNTB (n = 15) and HC (n = 20). Eight out of twelve cytokines achieved statistical relevance upon evaluation by pairwise and ROC analysis. Further, variable selection using random forest backward elimination revealed six serum biosignatures including IL-12, IL-4, IL-6, IL-10, IL-8 and TNF-β as optimal for classifying the LNTB status of an individual. For the sake of clinical applicability we further selected a three analyte panel (IL-8, IL-10 and TNF-β) which was subjected to multinomial modeling in the independent

    Lymphoblastoid cell lines (LCLs) transformed by Epstein-Barr virus (EBV) serve as an unlimited resource of human genomic DNA. The protocol that is widely used to establish LCLs involves peripheral blood mononuclear cell isolation by density gradient centrifugation, however, that method requires as much as 5 ml of peripheral blood. In this study, in order to provide a more simple and efficient method for the generation of LCLs, we developed a new protocol using hemolytic reaction to enrich white blood cells for EBV transformation and found that the hemolytic protocol successfully generated LCLs from a small volume (i.e., 0.1 ml) of peripheral blood. To assess the quality of genomic DNA extracted from LCLs established by the hemolytic protocol (LCL-hemolytic), we performed single nucleotide polymorphism (SNP) microarray genotyping using the GeneChip® 100 K Array Set (Affymetrix, Inc.). The concordances of the SNP genotyping resulting from genomic DNA from LCL-hemolytic (99.92%) were found to be as good as the technical replicate (99.90%), and Kappa statistics results confirmed the reliability. The findings of this study reveal that the hemolytic protocol is a simple and reliable method for the generation of LCLs, even from a small volume of peripheral blood. PMID:28272413

    Background There is difficulty in gathering data on the prevalence of human T-cell lymphotropic virus in blood donors as confirmatory testing is not mandatory in Brazil. This suggests there may be an underreporting of the prevalence. Objective To estimate the prevalence of human T-cell lymphotropic virus types 1 and 2 in donors of a blood bank in Caruaru, Brazil. Methods This was an observational, epidemiological, descriptive, longitudinal and retrospective study with information about the serology of donors of the Caruaru Blood Center, Fundação de Hematologia e Hemoterapia de Pernambuco (Hemope) from May 2006 to December 2010. The data were analyzed using the Excel 2010 computer program (Microsoft Office®). Results Of 61,881 donors, 60 (0.096%) individuals were identified as potential carriers of human T-cell lymphotropic virus types 1 and 2. Of these, 28 (0.045%) were positive and 32 (0.051%) had inconclusive results in the serological screening. Forty-five (0.072%) were retested; 17 were positive (0.027%) and 3 inconclusive (0.005%). After confirmatory tests, 8 were positive (0.013%). Six (75%) of the confirmed cases were women. Conclusion Epidemiological surveys like this are very important in order to create campaigns to attract donors and reduce the costs of laboratory tests. PMID:24106445

    Screening of blood donors for markers of transfusion-transmissible infectious agents leads to a varying number of false-reactive test results and sometimes thereby temporary or permanent deferral of donors and also to loss of collected units. Data on false-reactive screening test results in 2002 and 2003 were collected from 19 blood centers in Sweden. A questionnaire was sent to donors deferred because of false-reactive screening test results to investigate their perception of the information and their reaction to the deferral. Testing of 21,189 samples from new donors and 423,543 donations from regular and/or repeat donors produced 1,059 false-reactive test results, mostly from hepatitis C virus antibody testing, and 299 deferrals. Six different human immunodeficiency virus tests led to between 0.02 and 0.2 percent false-reactive results. The deferral rate varied considerably between different counties. Of 204 deferred donors contacted, 180 (88%) answered the questionnaire. More than 80 percent were worried about their test results and worry was more common among those who did not feel sufficiently informed. The results imply that there is a need for a more standardized approach to the screening of blood donors and donations with the aim of minimizing the number of false-reactive screening test results. They also emphasize the importance of appropriate information and support to deferred donors.

    The Pan American Health Organization's ProVac Initiative, designed to strengthen national decision making regarding the introduction of new vaccines, was initiated in 2004. Central to realizing ProVac's vision of regional capacity building, the ProVac Network of Centers of Excellence (CoEs) was established in 2010 to provide research support to the ProVac Initiative, leveraging existing capacity at Latin American and Caribbean (LAC) universities. We describe the process of establishing the ProVac Network of CoEs and its initial outcomes and challenges. A survey was sent to academic, not-for-profit institutions in LAC that had recently published work in the areas of clinical decision sciences and health economic analysis. Centers invited to join the Network were selected by an international committee on the basis of the survey results. Selection criteria included academic productivity in immunization-related work, team size and expertise, successful collaboration with governmental agencies and international organizations, and experience in training and education. The Network currently includes five academic institutions across LAC. Through open dialog and negotiation, specific projects were assigned to centers according to their areas of expertise. Collaboration among centers was highly encouraged. Faculty from ProVac's technical partners were assigned as focal points for each project. The resulting work led to the development and piloting of tools, methodological guides, and training materials that support countries in assessing existing evidence and generating new evidence on vaccine introduction. The evidence generated is shared with country-level decision makers and the scientific community. As the ProVac Initiative expands to other regions of the world with support from immunization and public health partners, the establishment of other regional and global networks of CoEs will be critical. The experience of LAC in creating the current network could benefit the

    The Food and Drug Administration (FDA) is further delaying, until December 1, 2008, the applicability date of a certain requirement of a final rule published in the Federal Register of December 3, 1999 (64 FR 67720) (the final rule). The final rule implements the Prescription Drug Marketing Act of 1987 (PDMA), as modified by the Prescription Drug Amendments of 1992 (PDA), and the Food and Drug Administration Modernization Act of 1997 (the Modernization Act). The provisions of the final rule became effective on December 4, 2000, except for certain provisions whose effective or applicability dates were delayed in five subsequent Federal Register notices, until December 1, 2006. The provision with the delayed applicability date would prohibit wholesale distribution of blood derivatives by registered blood establishments that meet the definition of a "health care entity." In the Federal Register of February 1, 2006 (71 FR 5200), FDA published a proposed rule specific to the distribution of blood derivatives by registered blood establishments that qualify as health care entities (the proposed rule). The proposed rule would amend certain limited provisions of the final rule to allow certain registered blood establishments that qualify as health care entities to distribute blood derivatives. In response to the proposed rule, FDA received substantive comments. As explained in the SUPPLEMENTARY INFORMATION section of this document, further delaying the applicability of Sec. 203.3(q) (21 CFR 203.3(q)) to the wholesale distribution of blood derivatives by health care entities is necessary to give the agency additional time to address comments on the proposed rule, consider whether regulatory changes are appropriate, and, if so, to initiate such changes.

    We conducted this study to explore the causal relationships between health literacy, individual characteristics, literacy, culture and society, cognitive ability, medication adherence, and the blood pressure levels of hypertensive older adults receiving health care services at Primary Health Care Centers in Sa Kaeo Province, Thailand. Six hundred hypertensive older adults had their blood pressure level recorded and were interviewed using questionnaires. Structural Equation Modeling (SEM) was used to determine the effect size, both direct and indirect, among factors. Almost half (48.7%) of studied subjects had inadequate health literacy, 98.3% had good medication adherence, and 80% had good blood pressure levels. The highest effect size on health literacy was literacy, followed by cognitive ability, and culture and society. Medication adherence was affected directly and indirectly by cognitive ability, literacy, and culture and society. Health literacy had not only a direct effect on medication adherence but was also the mediator. Finally, the highest effect size on blood pressure level was critical and communicative health literacy. These findings suggest that health literacy should be considered in the Health Literacy Program of the National Public Health Policy and Plan, Ministry of Public Health.

    Background. Continuous and efficient error management, including procedures from error detection to their resolution and prevention, is an important part of quality management in blood establishments. At the Croatian Institute of Transfusion Medicine (CITM), error management has been systematically performed since 2003. Materials and methods. Data derived from error management at the CITM during an 8-year period (2003–2010) formed the basis of this study. Throughout the study period, errors were reported to the Department of Quality Assurance. In addition to surveys and the necessary corrective activities, errors were analysed and classified according to the Medical Event Reporting System for Transfusion Medicine (MERS-TM). Results. During the study period, a total of 2,068 errors were recorded, including 1,778 (86.0%) in blood bank activities and 290 (14.0%) in blood transfusion services. As many as 1,744 (84.3%) errors were detected before issue of the product or service. Among the 324 errors identified upon release from the CITM, 163 (50.3%) errors were detected by customers and reported as complaints. In only five cases was an error detected after blood product transfusion however without any harmful consequences for the patients. All errors were, therefore, evaluated as “near miss” and “no harm” events. Fifty-two (2.5%) errors were evaluated as high-risk events. With regards to blood bank activities, the highest proportion of errors occurred in the processes of labelling (27.1%) and blood collection (23.7%). With regards to blood transfusion services, errors related to blood product issuing prevailed (24.5%). Conclusion. This study shows that comprehensive management of errors, including near miss errors, can generate data on the functioning of transfusion services, which is a precondition for implementation of efficient corrective and preventive actions that will ensure further improvement of the quality and safety of transfusion treatment.

    The hormone prolactin (PRL) plays a critical role in normal breast development by stimulating the proliferation of mammary cells, the production of milk proteins, and the formation of new mammary blood vessels. Unfortunately, the same cell and vessel growth pathways controlled by PRL in normal cells also operate in breast cancer cells, and elevated plasma PRL is a risk factor for breast cancer, especially in post-menopausal women.

    Thrombocytopenia frequently occurs in laboratory practice. The present work illustrates, through the presentation of a case report of Wiskott-Aldrich syndrome, the difficulties encountered to identify and characterize thrombocytopenia. The clinicobiological validation of a low platelet count involves both the biologist, who must assume the validation of numeration while mentioning the morphological characteristics of the platelets and other blood cells, as well as the physician who has to interpret these data according to the clinical context.

    Telomere length (TL) is considered a marker of biological aging and has been associated with the presence of various coronary risk factors in patients. Much less is known about the relationships between TL and classic coronary risk factors in other populations. We measured TL in peripheral blood leukocytes of 343 middle-aged blood donors (mean age 40.2 ± 12.4 years; 201 men, 142 women) using quantitative polymerase chain reaction. Median TL was 0.86 (range: 0.48–1.85) relative TL units. In linear regression analyses with natural log-transformed T to S ratio as the dependent variable, there was a significant association with age (per year: beta = -0.007, p<0.001) and sex (males vs. females: beta = 0.075, p = 0.007) with longer telomeres in men. After adjusting for these two variables, we observed no association of TL with classic coronary risk factors including cholesterol (p = 0.36), triglyceride (p = 0.09), HDL-cholesterol (p = 0.26), LDL-cholesterol (p = 0.36), smoking (p = 0.97), and personal (p = 0.46) or family history (p = 0.63) of cardiovascular disease. However, we did find a significant positive association with white (p = 0.011) and red blood cell count (p = 0.031), hemoglobin (p = 0.014) and hematocrit (p = 0.013); we also found a borderline positive association with thrombocytes (p = 0.074). Positive associations remained significant for hemoglobin (p = 0.017), hematocrit (p = 0.023), and leukocytes (p = 0.009) in a subgroup with no reported vascular disease; associations were of borderline significance for erythrocytes (p = 0.053) and thrombocytes (p = 0.088) in this subgroup. The data do not support the concept that classic coronary risk factors contribute to telomere attrition in a blood donor population. However, telomere attrition may be a marker for reduced proliferation reserve in hematopoietic progenitor cells. PMID:26445269

    Transition to the International Society of Blood Transfusion (ISBT) bar code-labeling standard known as ISBT 128 is scheduled to begin July 1, 1997. Blood centers play a pivotal role in educating and assisting hospitals with the implementation of the new standard. A communication plan and hospital guidelines to facilitate the actual transition to ISBT 128 are integral parts of a blood center's comprehensive implementation strategy. In Phase 1, the blood center identified specific target groups within the hospitals and developed educational materials for them. A survey tool was used to identify unique hospital needs. Subsequent blood center newsletters and customer service forums included ISBT 128 updates. In Phase 2, guidelines to assist hospitals with the identification of critical elements, milestones, and target dates for the transition were developed with hospital staff input. Survey results on the change to ISBT 128 showed that many hospitals were unfamiliar with this change and its effects on operational issues. Various forums to disseminate information about ISBT 128 are needed to provide education and assistance to diverse groups within the hospital. A partnership approach between hospitals and the regional blood center should promote a successful transition from the current bar code symbology, American Blood Commission Codabar, to ISBT 128.

    Health care workers are facing certain occupational hazards because of sharp injury and exposure to human blood and body fluids as a result of handling wastes. Though much attention is paid for the protection of these workers, the number of exposures and injuries do not show a sign of decline from time to time. To examine the occurrence of sharp injury and exposure to blood and body fluids in health care workers in health care centers in Ethiopia. In a case-control study, a randomly selected sample of 65 health facilities with 391 cases and 429 controls were studied. Data were collected through a self-administered questionnaire. Detailed analysis of exposure among the health care workers was done by logistic regression analysis with generalized estimating equations model to control correlation effects of responses within the cluster of health facilities. The number of health care workers who got sharp injury was 217 (26.5%). 296 (36.1%) had exposure to blood and body fluids. Working at Harari region (adjusted OR 0.44, 95% CI 0.26 to 0.75) and East Hararghea (adjusted OR 0.61, 95% CI 0.40 to 0.94), being male (adjusted OR 0.56, 95% CI 0.44 to 0.91), and a being nurse (adjusted OR 0.188, 95% CI 0.06 to 0.63) were independent risk factors of the exposure. Regardless of the anticipated low self-reporting for exposure status, the number of health care workers reported having sharp injury and exposure to blood and body fluids was high. Such high exposures indicate that health care workers are at high risk of acquiring blood-borne viral infections such as hepatitis B, hepatitis C, and HIV.

    The Center for HIV/AIDS Vaccine Immunology (CHAVI) consortium was established to determine the host and virus factors associated with HIV transmission, infection and containment of virus replication, with the goal of advancing the development of an HIV protective vaccine. Studies to meet this goal required the use of cryopreserved Peripheral Blood Mononuclear Cell (PBMC) specimens, and therefore it was imperative that a quality assurance (QA) oversight program be developed to monitor PBMC samples obtained from study participants at multiple international sites. Nine site-affiliated laboratories in Africa and the USA collected and processed PBMCs, and cryopreserved PBMC were shipped to CHAVI repositories in Africa and the USA for long-term storage. A three-stage program was designed, based on Good Clinical Laboratory Practices (GCLP), to monitor PBMC integrity at each step of this process. The first stage evaluated the integrity of fresh PBMCs for initial viability, overall yield, and processing time at the site-affiliated laboratories (Stage 1); for the second stage, the repositories determined post-thaw viability and cell recovery of cryopreserved PBMC, received from the site-affiliated laboratories (Stage 2); the third stage assessed the long-term specimen storage at each repository (Stage 3). Overall, the CHAVI PBMC QA oversight program results highlight the relative importance of each of these stages to the ultimate goal of preserving specimen integrity from peripheral blood collection to long-term repository storage.

    Background/Aims Bariatric surgery candidates often struggle when deciding between intensive lifestyle therapy, pharmacological therapy, and/or bariatric surgery for achieving their long-term weight loss (WL) goals. Moreover, they often have unrealistic WL expectations prior to surgery. Despite huge individual variation in surgically induced WL, patient education is currently based on average WL results derived from program experience or published literature. Improved patient education tools are needed to provide realistic individual expectations for surgical WL. The purpose of this study was to develop an electronic application for patient education that can aid in surgical decisions, establishing realistic WL goals, and monitoring WL success. Methods Post-operative weight measurements from 2608 Roux-en-Y gastric bypass patients at Geisinger Clinic were collected over an eight year period. While accounting for surgical BMI and age, quantile regression was used to create expected WL curves (10th, 25th, 50th, 75th, and 90th %tile) for the 36 month post-operative period. Results A mobile application (Get-2-Goal) was designed to provide a simple, personalized interface that allows patients to track their WL and compare their WL results to their expected WL curves. Get-2-Goal was made publicly available at no cost on a popular Apps store and is compatible with current smartphone and tablet technology (>1000 downloads to date). Get-2-Goal allows patients to input their personal profile (e.g. age, BMI), review their expected WL, and track their WL post-operatively. Patients have the option of saving a graphic containing their personalized WL curves and e-mailing a tabular form of their WL results to family, friends, and/or care providers. Conclusions Get-2-Goal is a simple tool that may be used by Bariatric Surgery Programs to facilitate electronic patient education. This tool may assist patients in deciding to proceed to WL surgery, and will facilitate early

    Several major unusual mortality events occurring in recent years have increased the level of concern for the health of bottlenose dolphin populations along the United States Atlantic and Gulf of Mexico coasts. Trace element concentrations were examined in a population of free-ranging dolphins in Sarasota Bay, Florida, in order to develop a benchmark for future comparisons within and between populations. Whole blood (n=51) and skin (n=40) samples were collected through capture and release health assessment events during 2002-2004. Samples were analyzed for Al, V, Cr, Mn, Cu, Zn, As, Se, Rb, Sr, Mo, Cd, and Pb by inductively coupled plasma mass spectrometry (ICPMS) and Hg via atomic fluorescence spectrometry (AFS). Trace element concentrations (wet mass) in skin were 2 to 45 times greater than blood, except Cu was approximately 1.5 times higher in blood. Statistically strong correlations (p<0.05) were found for V, As, Se, Rb, Sr, and Hg between blood and skin demonstrating that these tissues can be used as effective non-lethal monitoring tools. The strongest correlation was established for Hg (r=0.9689) and concentrations in both blood and skin were above the threshold at which detrimental effects are observed in other vertebrate species. Female dolphins had significantly greater Hg concentrations in blood and skin and Pb concentrations in skin, relative to males. Calves exhibited significantly lower V, As, and Hg concentrations in blood and V and Hg concentrations in skin, relative to other age classes. Rubidium and Cu concentrations in skin were greatest in subadults and calves, respectively. In blood, V, Zn, and As concentrations were significantly greater in winter, relative to summer, and the opposite trend was observed for Rb and Sr concentrations. In skin, Cu and Zn concentrations were significantly greater in winter, relative to summer, and the opposite trend was observed for Mn, Rb, Cd, and Pb concentrations.

    There is a constant shortage of red blood cells (RBCs) from sufficiently matched donors for patients who need chronic transfusion. Ex vivo expansion and maturation of human erythroid precursors (erythroblasts) from the patients or optimally matched donors could represent a potential solution. Proliferating erythroblasts can be expanded from umbilical cord blood mononuclear cells (CB MNCs) ex vivo for 106–107-fold (in ~50 days) before proliferation arrest and reaching sufficient number for broad application. Here, we report that ectopic expression of three genetic factors (Sox2, c-Myc, and an shRNA against TP53 gene) associated with iPSC derivation enables CB-derived erythroblasts to undergo extended expansion (~1068-fold in ~12 months) in a serum-free culture condition without change of cell identity or function. These expanding erythroblasts maintain immature erythroblast phenotypes and morphology, a normal diploid karyotype and dependence on a specific combination of growth factors for proliferation throughout expansion period. When being switched to a terminal differentiation condition, these immortalized erythroblasts gradually exit cell cycle, decrease cell size, accumulate hemoglobin, condense nuclei and eventually give rise to enucleated hemoglobin-containing erythrocytes that can bind and release oxygen. Our result may ultimately lead to an alternative approach to generate unlimited numbers of RBCs for personalized transfusion medicine. PMID:24002691

    The aim of the study is to present the results and experience in the management of complaints in a transfusion service in order to draw attention to the importance of this segment of quality management and to stimulate publication of other studies on the topic. This study is based on data from the Croatian Institute of Transfusion Medicine obtained by analysis of complaints recorded during a 13-year period (1998-2010). The distribution of the types and frequencies of complaints is presented, along with the level of their justifiability and criticality. The dynamics of the complaints is analysed overall and within particular categories. In addition, corrective actions and other factors that may have influenced the trends observed are discussed. During the study period, 817 complaints were received, most of which (40.9%) referred to the positive direct antiglobulin test in red cell concentrates, followed by blood product issuing and distribution (12.9%) and blood product quality (9.4%). Of the 817 complaints, 177 (21.7%) were assessed as serious and 645 (78.9%) as justified based on the testing performed. Data collected by systematic recording and analysis of complaints provide a basis for problem identification, implementation of corrective and preventive actions, and improvement of product and service quality, and, thereby, customer satisfaction.

    Background. Despite advancements in comprehension of molecular mechanisms governing bone marrow (BM) homing of hematopoietic stem cells, cord blood transplant (CBT) suffers from a slow rate of hematopoietic recovery. Intrabone (IB) injection has been proposed as a method able to improve speed of BM engraftment with respect to conventional IV protocols. However, the mechanisms underlying this benefit are largely unknown. Aim. To verify whether IB-CBT determines a local engraftment able to predict the reconstitution of recipient hematopoiesis. Design and Methods. Twenty-one patients with hematologic malignancies received IB injection into both iliac crests of 3.2 ± 0.68 ∗ 107/kg cord blood cells. One month following IB-CBT, PET-CT imaging was performed. Maximal standardized uptake values (SUVs) were assessed in BM of both iliac crests and in all lumbar vertebrae. Results. Maximal SUV within iliac crests was higher than in lumbar vertebrae (4.1 ± 1.7 versus 3.2 ± 0.7, resp., P = 0.01). However, metabolic activity in these two different BM districts was significantly correlated (r = 0.7, P < 0.001). Moreover, FDG uptake values within the injection site closely predicted platelet recovery 100 days after IB-CBT (r = 0.72, P < 0.01). Conclusions. The metabolic activity of injected BM predicts the subsequent rate of hematopoietic recovery after IB-CBT, suggesting a pivotal role of the local engraftment in the reconstitution of recipient hematopoiesis.

    Background: After 4 months of the establishment of palliative care center (PCC) in our institute, we present an audit of the sociodemographic parameters of admitted patients. Such an audit can help to recognize the lacuna in the management and thus help to identify the specific requirements of cancer patients that might be overlooked in a busy cancer center. Materials and Methods: A total of 234 patients were admitted in our PCC since its inception in October 2013. The study design was retrospective, collecting the data from the medical records of the patients. The descriptive statistics of all these data were calculated in terms of frequencies and percentage of categorical variables. Results: Out of 234 patients admitted in PCC, 156 (66%) were male. The median age of the patients was 54 years. A total of 44% patients had primary malignancy of head and neck, 14% of cervical, 17% of lung cancer, 6% of breast, and 5% of colon, respectively. Metastatic disease was present in 76% of the patients admitted in the PCC. Liver was the most common (46%) metastatic site. Total 13 symptoms were identified with mean number of symptoms per patient at admission in PCC being 5.17. Conclusions: Palliative care services are an indispensable part of a tertiary regional cancer care center. The oncologists should be made aware of the requirement of better relief of pain and other distressing symptoms to provide better quality of life to the patients suffering from advanced cancer.

    The World Trade Center (WTC) collapse generated caustic airborne particulates that caused chronic rhinosinusitis in exposed Fire Department of New York firefighters. Surgery was performed when symptoms remained uncontrolled despite medical management. To identify predictors of surgical intervention for chronic rhinosinusitis in firefighters exposed to airborne irritants at the WTC collapse site. We assessed in 8,227 firefighters with WTC exposure between September 11, 2001 (9/11), and September 25, 2001, including WTC-site arrival time, months of rescue and recovery work, and eosinophil concentration measured between 9/11 and March 10, 2003. We assessed the association of serum cytokines and immunoglobulins with eosinophil concentration and surgery for rhinosinusitis in 112 surgical cases and 376 control subjects with serum available from the first 6 months after exposure to the WTC collapse site. Between 9/11 and March 10, 2015, the surgery rate was 0.47 cases per 100 person-years. In the first 18 months post-9/11, surgical patients had higher mean blood eosinophil levels than study cohort patients (219 ± 155 vs. 191 ± 134; P < 0.0001). Increased surgery risk was associated with increasing blood eosinophil counts (hazard ratio [HR], 1.12 per 100 cells/μl; 95% confidence interval [CI], 1.07-1.17; P < 0.001); arriving at the WTC site on 9/11 or September 12, 2001 (HR, 1.43; 95% CI, 1.04-1.99; P = 0.03); and working 6 months or longer at the WTC site (HR, 1.48; 95% CI, 1.14-1.93; P < 0.01). Median blood eosinophil levels for surgical patients were above levels for the cohort in all 18-month intervals March 11, 2000, through March 10, 2015, using 51,163 measurements representing 97,733 person-years of observation. Increasing age, increasing IL-17A, and low IgA in serum from 2001 to 2002 predicted blood eosinophil concentration in surgical patients but not in control subjects (R(2) = 0.26, P < 0.0001; vs. R(2) = 0.008, P = 0

    Lymphoedema is increasingly recognized as a significant problem in healthcare. The number of patients is growing, posing a future challenge to healthcare systems and economics. Over the past decade, specialized lymphoedema management has been established around the world to accommodate the growing demands. However, information on organization, experiences and outcome are scarce. To conduct a clinical perspective analysis describing the establishment, organization, function and results of a new, multidisciplinary lymphoedema centre functioning as a university hospital unit in connection to a department of dermatology and the Copenhagen Wound Healing Center and integrated as a national expert function in the public healthcare organization of Denmark. Data were collected following the establishment of a lymphoedema centre based on the structured, multidisciplinary organization of lymphoedema management. During the first 4·5 years a total of 8058 patient consultations were performed. The mean duration of symptoms at the first visit was 19 years (range 1-67) and 31% of patients had never received any diagnosis or treatment prior to referral. Complications were found in 48% of referred patients. All patients received appropriate diagnostic investigations and treatment according to best practice. Multidisciplinary assessment involving four or more different healthcare professions was needed in 86% of cases. Research opportunities and expert education of staff were enhanced. A multidisciplinary lymphoedema centre improves management, knowledge and awareness of lymphoedema. This model, with minor adjustments, may be applicable for other regions and countries. © 2012 The Authors. BJD © 2012 British Association of Dermatologists.

    The prevalence of somatic chromosomal abnormalities in infertile male individuals has been reported to vary in different literatures. The aim of this study was to investigate the frequency of chromosomal aberrations among infertile men referred to the Cytogenetic Laboratory of Iran Blood Transfusion Organization Research Centre (IBTO). Chromosomal analysis was performed on phytohemag-glutinin (PHA)-stimulated peripheral lymphocyte cultures of 1052 infertile men using standard cytogenetic methods. The study took place during 1997 to 2007. Total chromosome alterations were revealed in 161 (15.30%) infertile men. The most prevalent chromosomal abnormality in the infertile men was 47, XXY, that was seen in 94 (58.38%) men while one of them had a mosaic karyotype: mos 47, XX[54]/47,XXY[18]/46,XY[9]. In 37 (22.98%) cases, structural aberrations were detected. There were 30 (18.63%) cases of sex reversal. Cytogenetic studies of these patients showed increased chromosomal abnormalities in infertile men in comparison with that of the normal population, justifying the need for cytogenetic analysis of men with idiopathic infertility.

    In August and November 2010 we collected and examined peripheral blood and tissues from three species of Gulf of Mexico fish. Findings were compared to non-exposed control fish. The leukocyte counts of exposed alligator gar were not significantly different from controls, while exposed Gulf killifish and sea trout had significantly decreased lymphocyte counts. Liver ethoxyresorufin-O-deethylase (EROD) values from sea trout were significantly greater than control sea trout EROD values, suggesting poly aromatic hydrocarbon exposure. Splenic melano-macrophage centers (MMCs) from exposed sea trout and Gulf killifish showed a significant increase in number compared to non-exposed fish. Sea trout splenic MMCs were also significantly greater in size. These findings suggest that Gulf fish sampled were exposed to crude oil from the Macondo well and were in a lymphopenic or immuno-compromised state.

    One to five weeks of chronic exposure to hypoxia has been shown to reduce peak blood lactate concentration compared to acute exposure to hypoxia during exercise, the high altitude ‘lactate paradox’. However, we hypothesize that a sufficiently long exposure to hypoxia would result in a blood lactate and net lactate release from the active leg to an extent similar to that observed in acute hypoxia, independent of work intensity. Six Danish lowlanders (25–26 years) were studied during graded incremental bicycle exercise under four conditions: at sea level breathing either ambient air (0 m normoxia) or a low-oxygen gas mixture (10 % O2 in N2, 0 m acute hypoxia) and after 9 weeks of acclimatization to 5260 m breathing either ambient air (5260 m chronic hypoxia) or a normoxic gas mixture (47 % O2 in N2, 5260 m acute normoxia). In addition, one-leg knee-extensor exercise was performed during 5260 m chronic hypoxia and 5260 m acute normoxia. During incremental bicycle exercise, the arterial lactate concentrations were similar at sub-maximal work at 0 m acute hypoxia and 5260 m chronic hypoxia but higher compared to both 0 m normoxia and 5260 m acute normoxia. However, peak lactate concentration was similar under all conditions (10.0 ± 1.3, 10.7 ± 2.0, 10.9 ± 2.3 and 11.0 ± 1.0 mmol l−1) at 0 m normoxia, 0 m acute hypoxia, 5260 m chronic hypoxia and 5260 m acute normoxia, respectively. Despite a similar lactate concentration at sub-maximal and maximal workload, the net lactate release from the leg was lower during 0 m acute hypoxia (peak 8.4 ± 1.6 mmol min−1) than at 5260 m chronic hypoxia (peak 12.8 ± 2.2 mmol min−1). The same was observed for 0 m normoxia (peak 8.9 ± 2.0 mmol min−1) compared to 5260 m acute normoxia (peak 12.6 ± 3.6 mmol min−1). Exercise after acclimatization with a small muscle mass (one-leg knee-extensor) elicited similar lactate concentrations (peak 4.4 ± 0.2 vs. 3.9 ± 0.3 mmol l−1) and net lactate release (peak 16.4 ± 1

    Background Gram-negative bacteremia is one of the leading causes of mortality and morbidity in Indian hospitals. We hereby describe changing trends in Gram-negative isolates from blood cultures from a single center over a ten-year period. Methods Antibiotic susceptibility patterns were collected for a total of 4128 non-repetitive blood culture isolates from 2003 to 2013. We analyzed clinically important Gram-negative isolates (Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa and Acinetobacter baumannii) and their susceptibility pattern. A. baumannii was studied between 2009 and 2013 only. Results There was a steady increase in extended-spectrum beta-lactamase (ESBL) production in E. coli (56% to 80%) and an even steeper increase in K. pneumoniae (50% to 81%). Susceptibility to carbapenems fell marginally for E. coli (p = .242) but significantly for K. pneumoniae (p = .000) and P. aeruginosa (.0005). All these changes were seen irrespective of the source of the isolate (outpatient, inpatient and critical care unit – CCU), with a statistically significant fall among CCU isolates of K. pneumoniae and P. aeruginosa. P. aeruginosa was more susceptible to carbapenems than beta-lactam /beta-lactamase inhibitors until 2009, but thereafter the pattern reversed. A. baumannii was isolated from the CCU only: 75% were resistant to carbapenems and susceptible only to polymyxin E and tigecycline. Conclusion There was a progressive increase in antimicrobial resistance in isolates of E. coli, K. pneumoniae, P. aeruginosa and A. baumannii isolated from blood cultures. ESBL production was seen in the majority of isolates of E. coli and K. pneumoniae. Carbapenem resistance in K. pneumoniae and E. coli is increasing rapidly. Resistance to even tigecycline and polymyxin E, antibiotics of last resort, has begun to emerge. There is an urgent need for antimicrobial stewardship and other measures to limit worsening of Gram-negative resistance in India. PMID:26405674

    The Minority-Based Community Clinical Oncology Program (MB-CCOP) at University of Medicine and Dentistry of New Jersey, New Jersey Medical School-University Hospital Cancer Center was established to serve an unmet need in a medically, educationally, and socioeconomically underserved community of primarily African American and Latino patients in Newark and Essex County, New Jersey. The MB-CCOP was built on an existing infrastructure of multidisciplinary teams of cancer specialists who collaborated in patient care and an existing clinical research program, which included multilingual staff and a breast cancer navigator. This article highlights some of the unique opportunities and challenges involved in the startup of an MB-CCOP specifically relevant to an academic setting. We present a guide to the necessary infrastructure and institutional support that must be in place before considering such a program and some of the steps an institution can take to overcome barriers preventing successful enrollment of patients onto clinical trials.

    We established age- and gender-specific reference ranges for the 36 routine complete blood cell (CBC) and 57 cell population data (CPD) items in the Sysmex XN-2000 (Sysmex, Japan). In total, 280 peripheral blood samples were obtained from an equal number of healthy adults. Values for 36 routine items and 57 CPD items were obtained for each sample, and the results were categorized into six subgroups (N>39 in each subgroup) according to patient age (20-40, 41-60, and >60 yr) and gender (male and female), and compared with respect to age and gender differences. The majority of data items (22 of 36 routine CBC items and 44 of 57 CPD items) exhibited significant differences (P≤0.05) in their results with respect to age or gender, and several red cell-, lymphocyte-, and platelet-related data tended to decrease in women or older adults. These results provide a basis for establishing age- and gender-specific reference ranges for routine and CPD items in Sysmex XN-2000. Furthermore, these reference ranges could be used to determine clinical significance for new items of Sysmex XN-2000 in further studies.

    The need for education about oral health conditions has been discussed in recent years. Current research has shown correlations between oral and systemic disease. Disease entities have been connected to bacteremia and inflammatory process es, both of which can result from oral pathologies. Professionals need to be educated about these connections and advised how, by maintaining proper oral health, they may avoid systemic consequences. Students in dental hygiene, health care management and nursing programs can play a vital role in this education. By jointly creating and operating an educational Center for Oral Health Promotion, they can better understand each other's professions. This will facilitate developing the skill set to reach out to the underserved and establish protocols to provide health literacy and care at affordable rates. They can also better appreciate the interconnections between health care delivery and its management while gaining skills needed to work in an inter-professional setting. A Center for Oral Health Promotion would expand services typically offered in dental hygiene educational settings as well as expand dental hygiene, nursing and health care management student experiences.

    The aim of this study was to explore the perceptions of stakeholders regarding a newly established dental school with a problem-based, student-led, patient-centered curriculum in a community setting. Qualitative methods using 16 semistructured interviews and two focus groups were used to engage a range of stakeholders from students to faculty members to practitioners. Purposive sampling was employed with participants contacted through professional channels. Interview and focus group transcripts were transcribed verbatim. The data were analyzed thematically using an inductive approach. Themes related to preparedness of dental graduates were identified during data analyses. Early clinical exposure with patients in the first year of the course, holistic care using a patient-centered approach, and the acquisition of communication skills, professionalism, team-working skills, reflective practice, and evidence-informed clinical practice were perceived to be key strengths of the curriculum. The participants also expressed the need to strengthen teaching of life sciences and provide additional clinical experience in simulated general dental practice clinics. This study provides insight into the perceptions of a wide range of stakeholders and provides a deeper understanding of the merits and challenges of an innovative undergraduate dental curriculum.

    2012-01-01

    Background To report on establishment of workflow and clinical results of particle therapy at the Heidelberg Ion Therapy Center. Materials and methods We treated 36 pediatric patients (aged 21 or younger) with particle therapy at HIT. Median age was 12 years (range 2-21 years), five patients (14%) were younger than 5 years of age. Indications included pilocytic astrocytoma, parameningeal and orbital rhabdomyosarcoma, skull base and cervical chordoma, osteosarcoma and adenoid-cystic carcinoma (ACC), as well as one patient with an angiofibroma of the nasopharynx. For the treatment of small children, an anesthesia unit at HIT was established in cooperation with the Department of Anesthesiology. Results Treatment concepts depended on tumor type, staging, age of the patient, as well as availability of specific study protocols. In all patients, particle radiotherapy was well tolerated and no interruptions due to toxicity had to be undertaken. During follow-up, only mild toxicites were observed. Only one patient died of tumor progression: Carbon ion radiotherapy was performed as an individual treatment approach in a child with a skull base recurrence of the previously irradiated rhabdomyosarcoma. Besides this patient, tumor recurrence was observed in two additional patients. Conclusion Clinical protocols have been generated to evaluate the real potential of particle therapy, also with respect to carbon ions in distinct pediatric patient populations. The strong cooperation between the pediatric department and the department of radiation oncology enable an interdisciplinary treatment and stream-lined workflow and acceptance of the treatment for the patients and their parents.

    Self-monitoring of blood glucose (BG) by means of handheld BG systems is a cornerstone in diabetes therapy. The aim of this article is to describe a procedure with proven traceability for calibration and evaluation of BG systems to guarantee reliable BG measurements. Isotope dilution gas chromatography mass spectrometry (ID/GC/MS) is a method that fulfills all requirements to be used in a higher-order reference measurement procedure. However, this method is not applicable for routine measurements because of the time-consuming sample preparation. A hexokinase method with perchloric acid (PCA) sample pretreatment is used in a measurement procedure for such purposes. This method is directly linked to the ID/GC/MS method by calibration with a glucose solution that has an ID/GC/MS-determined target value. BG systems are calibrated with whole blood samples. The glucose levels in such samples are analyzed by this ID/GC/MS-linked hexokinase method to establish traceability to higher-order reference material. For method comparison, the glucose concentrations in 577 whole blood samples were measured using the PCA-hexokinase method and the ID/GC/MS method; this resulted in a mean deviation of 0.1%. The mean deviation between BG levels measured in >500 valid whole blood samples with BG systems and the ID/GC/MS was 1.1%. BG systems allow a reliable glucose measurement if a true reference measurement procedure, with a noninterrupted traceability chain using ID/GC/MS linked hexokinase method for calibration of BG systems, is implemented. Systems should be calibrated by means of a traceable and defined measurement procedure to avoid bias. PMID:24876614

    A nationwide multicentre study was conducted to establish well-defined reference intervals (RIs) of haematological parameters for the Turkish population in consideration of sources of variation in reference values (RVs). K2-EDTA whole blood samples (total of 3363) were collected from 12 laboratories. Sera were also collected for measurements of iron, UIBC, TIBC, and ferritin for use in the latent abnormal values exclusion (LAVE) method. The blood samples were analysed within 2 hours in each laboratory using Cell Dyn and Ruby (Abbott), LH780 (Beckman Coulter), or XT-2000i (Sysmex). A panel of freshly prepared blood from 40 healthy volunteers was measured in common to assess any analyser-dependent bias in the measurements. The SD ratio (SDR) based on ANOVA was used to judge the need for partitioning RVs. RIs were computed by the parametric method with/without applying the LAVE method. Analyser-dependent bias was found for basophils (Bas), MCHC, RDW and MPV from the panel test results and thus those RIs were derived for each manufacturer. RIs were determined from all volunteers' results for WBC, neutrophils, lymphocytes, monocytes, eosinophils, MCV, MCH and platelets. Gender-specific RIs were required for RBC, haemoglobin, haematocrit, iron, UIBC and ferritin. Region-specific RIs were required for RBC, haemoglobin, haematocrit, UIBC, and TIBC. With the novel use of a freshly prepared blood panel, manufacturer-specific RIs' were derived for Bas, Bas%, MCHC, RDW and MPV. Regional differences in RIs were observed among the 7 regions of Turkey, which may be attributed to nutritional or environmental factors, including altitude.

    Rationale: The World Trade Center (WTC) collapse generated caustic airborne particulates that caused chronic rhinosinusitis in exposed Fire Department of New York firefighters. Surgery was performed when symptoms remained uncontrolled despite medical management. Objectives: To identify predictors of surgical intervention for chronic rhinosinusitis in firefighters exposed to airborne irritants at the WTC collapse site. Methods: We assessed in 8,227 firefighters with WTC exposure between September 11, 2001 (9/11), and September 25, 2001, including WTC-site arrival time, months of rescue and recovery work, and eosinophil concentration measured between 9/11 and March 10, 2003. We assessed the association of serum cytokines and immunoglobulins with eosinophil concentration and surgery for rhinosinusitis in 112 surgical cases and 376 control subjects with serum available from the first 6 months after exposure to the WTC collapse site. Measurements and Main Results: Between 9/11 and March 10, 2015, the surgery rate was 0.47 cases per 100 person-years. In the first 18 months post-9/11, surgical patients had higher mean blood eosinophil levels than study cohort patients (219 ± 155 vs. 191 ± 134; P < 0.0001). Increased surgery risk was associated with increasing blood eosinophil counts (hazard ratio [HR], 1.12 per 100 cells/μl; 95% confidence interval [CI], 1.07–1.17; P < 0.001); arriving at the WTC site on 9/11 or September 12, 2001 (HR, 1.43; 95% CI, 1.04–1.99; P = 0.03); and working 6 months or longer at the WTC site (HR, 1.48; 95% CI, 1.14–1.93; P < 0.01). Median blood eosinophil levels for surgical patients were above levels for the cohort in all 18-month intervals March 11, 2000, through March 10, 2015, using 51,163 measurements representing 97,733 person-years of observation. Increasing age, increasing IL-17A, and low IgA in serum from 2001 to 2002 predicted blood eosinophil concentration in surgical patients but not in control

    Previous studies have identified healthcare practices that may place undue pressure on related donors (RDs) of hematopoietic cell products and an increase in serious adverse events associated with morbidities in this population. As a result, specific requirements to safeguard RD health have been introduced to Foundation for the Accreditation of Cellular Therapy/The Joint Accreditation Committee ISCT and EBMT (FACT-JACIE) Standards, but the impact of accreditation on RD care has not previously been evaluated. A survey of transplant program directors of European Group for Blood and Marrow Transplantation member centers was conducted by the Donor Health and Safety Working Committee of the Center for International Blood and Marrow Transplant Research to test the hypothesis that RD care in FACT-JACIE accredited centers is more closely aligned with international consensus donor care recommendations than RD care delivered in centers without accreditation. Responses were received from 39% of 304 centers. Our results show that practice in accredited centers was much closer to recommended standards as compared with nonaccredited centers. Specifically, a higher percentage of accredited centers use eligibility criteria to assess RDs (93% versus 78%; P = .02), and a lower percentage have a single physician simultaneously responsible for an RD and their recipient (14% versus 35%; P = .008). In contrast, where regulatory standards do not exist, both accredited and nonaccredited centers fell short of accepted best practice. These results raise concerns that despite improvements in care, current practice can place undue pressure on donors and may increase the risk of donation-associated adverse events. We recommend measures to address these issues through enhancement of regulatory standards as well as national initiatives to standardize RD care.

  3. Agreement between the Government of the Republic of Chile and ESO for Establishing a New Center for Observation in Chile - ALMA

    NASA Astrophysics Data System (ADS)

    2002-10-01

    On October 21, 2002, the Minister of Foreign Affairs of the Republic of Chile, Mrs. María Soledad Alvear and the ESO Director General, Dr. Catherine Cesarsky , signed an Agreement that authorizes ESO to establish a new center for astronomical observation in Chile . This new center for astronomical observation will be for the Atacama Large Millimeter Array (ALMA) , the largest ground based astronomical project for the next decades. On this occasion, Minister Alvear stated that "we want to have ALMA working as soon as possible, which will constitute a pride not only to Chilean scientists but for the whole country and in particular, for the community of the Antofagasta Region" . ESO Director General Cesarsky said that "signing this agreement between the Government of Chile and ESO is a historical step in the astronomical collaboration between Chile and ESO and it will allow Chile to host, once again, a project of worldwide interest and impact" . ALMA is a joint project on equal basis between ESO and AUI (Associated Universities, Inc.). These organizations represent the scientific interests of Europe on one side and the United States with Canada on the other side. Chilean astronomers are closely involved with the project and 10% of the observing time will be reserved for Chilean science. ALMA will be built in the Andes, on the Plateau of Chajnantor (see the Chajnantor Photo Gallery ), 5000 metres above sea level and 60 km East of the town of San Pedro de Atacama. The array will be comprised of 64 antennas with unprecedent sensitivity and angular resolution that will allow studying the origin of galaxies, stars and planets, opening new horizons for astronomy, and being able to observe galaxies across the universe where stars are being formed. The agreement now signed between ESO and the Government of the Republic of Chile recognizes the interest that the ALMA Project has for Chile, as it will deepen and strengthen the cooperation in scientific and technological matters

  4. A facile method to establish human induced pluripotent stem cells from adult blood cells under feeder-free and xeno-free culture conditions: a clinically compliant approach.

    Reprogramming human adult blood mononuclear cells (MNCs) cells by transient plasmid expression is becoming increasingly popular as an attractive method for generating induced pluripotent stem (iPS) cells without the genomic alteration caused by genome-inserting vectors. However, its efficiency is relatively low with adult MNCs compared with cord blood MNCs and other fetal cells and is highly variable among different adult individuals. We report highly efficient iPS cell derivation under clinically compliant conditions via three major improvements. First, we revised a combination of three EBNA1/OriP episomal vectors expressing five transgenes, which increased reprogramming efficiency by ≥10-50-fold from our previous vectors. Second, human recombinant vitronectin proteins were used as cell culture substrates, alleviating the need for feeder cells or animal-sourced proteins. Finally, we eliminated the previously critical step of manually picking individual iPS cell clones by pooling newly emerged iPS cell colonies. Pooled cultures were then purified based on the presence of the TRA-1-60 pluripotency surface antigen, resulting in the ability to rapidly expand iPS cells for subsequent applications. These new improvements permit a consistent and reliable method to generate human iPS cells with minimal clonal variations from blood MNCs, including previously difficult samples such as those from patients with paroxysmal nocturnal hemoglobinuria.

    Reprogramming human adult blood mononuclear cells (MNCs) cells by transient plasmid expression is becoming increasingly popular as an attractive method for generating induced pluripotent stem (iPS) cells without the genomic alteration caused by genome-inserting vectors. However, its efficiency is relatively low with adult MNCs compared with cord blood MNCs and other fetal cells and is highly variable among different adult individuals. We report highly efficient iPS cell derivation under clinically compliant conditions via three major improvements. First, we revised a combination of three EBNA1/OriP episomal vectors expressing five transgenes, which increased reprogramming efficiency by ≥10–50-fold from our previous vectors. Second, human recombinant vitronectin proteins were used as cell culture substrates, alleviating the need for feeder cells or animal-sourced proteins. Finally, we eliminated the previously critical step of manually picking individual iPS cell clones by pooling newly emerged iPS cell colonies. Pooled cultures were then purified based on the presence of the TRA-1-60 pluripotency surface antigen, resulting in the ability to rapidly expand iPS cells for subsequent applications.

    As in other countries, Moroccan health-care workers are exposed to occupational blood exposure (OBE) hazards. The purpose of this study was to estimate the occupational safety and hygiene conditions determining the OBE risk for health-care workers. WORKERS AND METHODS: In March 2000, a multicentric study was carried out in Morocco on 420 health-care workers, with an anonymous questionnaire. The study included health-care workers in the Taza and Temara hospitals and health centers, as well as in a Rabat public medical analysis laboratory. The participation rate was 67.8% (285/420). The population was mainly female (61%) with a mean age of 41.4 years (+/-7 years). Health-care workers answered that: occupational hygiene and safety were inadequate (55.1%); wearing single-use gloves was rare (34.5%); resheathing used needles was frequent (74.5%); safe containers were often missing (67%). In 1999, the annual average incidence of OBE was 1.5 (+/-4.3) per capita. If we consider the whole career of health-care workers, the incidence reached about 14.3+/-28.1 per capita. The absence of post-exposure chemoprophylaxis was the rule. The study shows that there is a need to improve occupational hygiene and safety conditions for Moroccan health-care workers in order to reduce OBE hazards.

    Aggressive NK cell leukemia (ANKL) is an exceedingly rare form of leukemia and carries a poor prognosis, with a median survival of only 2 months. Using the Center for International Blood and Marrow Transplant Research database, we evaluated outcomes of allogeneic hematopoietic cell transplantation (alloHCT) in patients with ANKL. Twenty-one patients with a centrally confirmed diagnosis of ANKL were included. Median patient age was 42 years and 15 patients (71%) were Caucasian. Fourteen patients (67%) were in complete remission (CR) at the time of alloHCT, and 5 patients had active disease. Median follow-up of survivors was 25 months (range, 12 to 116). The 2-year estimates of nonrelapse mortality, relapse/progression, progression-free (PFS), and overall survival (OS) were 21%, 59%, 20%, and 24%, respectively. The 2-year PFS of patients in CR at the time of alloHCT was significantly better than that of patients with active disease at transplantation (30% versus 0%; P = .001). The 2-year OS in similar order was 38% versus 0% (P < .001). In conclusion, this registry analysis that included majority non-Asian patient population shows that alloHCT can provide durable disease control in a subset of ANKL patients. Achieving CR before transplantation appears to be a prerequisite for successful transplantation outcomes.

    Policy, environmental, and systems-level interventions are part of a comprehensive approach to managing high blood pressure and high cholesterol, which are key risk factors for heart disease and stroke. In this qualitative case study, we identified clinical practices in health care organizations that used policy, environmental, or systems-level interventions to improve patient outcomes for these conditions. Our 4 objectives were to describe 1) policy, environmental, and systems-level interventions; 2) enabling factors and barriers that affected implementation; 3) methods for evaluating the success of the intervention; and 4) lessons learned from the health care practices that implemented these interventions. Through literature review and expert guidance, we identified 34 health care practices that used policy, environmental, and systems-level interventions to manage high blood pressure and high cholesterol. In 2003, we conducted case study interviews with key informants for 9 health care practices that 1) demonstrated improved patient outcomes for blood pressure or cholesterol; 2) implemented the interventions for at least 1 year; and 3) remained committed to sustaining or institutionalizing interventions. We taped and transcribed the interviews and used Centers for Disease Control and Prevention EZ-Text software (www.cdc.gov/hiv/software/ez-text.htm) to code, categorize, and analyze the responses. The health care practices we studied implemented specialized lipid clinics, disease management programs, physician reminder systems, and participation in the Health Resources and Services Administration's Bureau of Primary Care Health Disparities Collaboratives. All practices used comprehensive systems for patient care that were well-defined, measurable, and linked to desirable patient outcomes. Most relied on data systems to identify patients targeted for the interventions and practice areas that needed improvement, and to track the progress of patients and

    Outcome of arterial switch operation for transposition of the great arteries with/without ventricular septal defect is a service key-performance-indicator. The aim of the authors was to assess patient characteristics and parameters in the perioperative course. In the setting of a newly-established, comprehensive tertiary-care center, primary complete repair was performed including associated anomalies, e.g. transverse arch repairs. Patients with d-transposition were grouped according to coexistence of ventricular septal defect. 118 arterial switch operations were performed between 2007 and 2014 with 96.62% survival (114/118). Ventricular septal defect and repair of associated anomalies did not yield worse outcome. Left ventricular re-training with late presentation necessitated mechanical circulatory support for 4.5±1.5 days. D-transposition is suitable for standardization of clinical algorithm and surgical technique. Quality standards contribute to excellent outcomes, minimize complications, and serve as blueprint for other neonatal open-heart procedures. Availability of mechanical circulatory support is key for single-stage left ventricular re-training beyond the neonatal period.

    In recent years, issues in medical business ethics (MBE), such as conflicts of interest (COI), Medicare fraud and abuse, and the structure and functioning of reimbursement systems, have received significant attention from the media and professional associations in the United States. As a result of highly publicized instances of financial interests altering physician decision-making, major professional organizations and government bodies have produced reports and guidelines to encourage self-regulation and impose rules to limit physician relationships with for-profit entities. Nevertheless, no published curricula exist in the area of MBE. This study aimed to establish a baseline level of knowledge and the educational goals medical students and residents prioritize in the area of MBE. 732 medical students and 380 residents at two academic medical centers in the state of Missouri, USA, completed a brief survey indicating their awareness of major MBE guidance documents, knowledge of key MBE research, beliefs about the goals of an education in MBE, and the areas of MBE they were most interested in learning more about. Medical students and residents had little awareness of recent and major reports on MBE topics, and had minimal knowledge of basic MBE facts. Residents scored statistically better than medical students in both of these areas. Medical students and residents were in close agreement regarding the goals of an MBE curriculum. Both groups showed significant interest in learning more about MBE topics with an emphasis on background topics such as "the business aspects of medicine" and "health care delivery systems". The content of major reports by professional associations and expert bodies has not trickled down to medical students and residents, yet both groups are interested in learning more about MBE topics. Our survey suggests potentially beneficial ways to frame and embed MBE topics into the larger framework of medical education.

    Feed restriction, and seasonal weight loss (SWL), are major setbacks for animal production in the tropics and the Mediterranean. They may be solved through the use of autochthonous breeds particularly well adapted to SWL. It is therefore of major importance to determine markers of tolerance to feed restriction of putative use in animal selection. Two indigenous breeds from the Canary Islands, Palmera and Majorera, are commonly used by dairy goat farmers and, interestingly, have different phenotype characteristics albeit with a common ancestry. Indeed, Majorera is well adapted to feed restriction whereas the Palmera is susceptible to feed restriction. In addition, regardless of their importance in dairy production, there are only a limited number of reports relating to these breeds and, to the best of our knowledge, there is no description of their blood metabolite standard values under control conditions or as affected by feed restriction. In this study we analysed the blood metabolite profiles in Majorera and Palmera goats aiming to establish the differential responses to feed restriction between the two breeds and to characterise their metabolite standard values under control conditions. We observed significant differences in creatinine, urea, non-esterified fatty acids (NEFAs), cholesterol, IGF-1 and T3 due to underfeeding. Furthermore, a PCA analysis, revealed that animals submitted to undernutrition could be distinguished from the control groups, with the formation of three separate clusters (Palmera individuals after 22 d of subnutrition (PE22); Majorera individuals after 22 d of subnutrition (ME22) and animals assigned to control conditions (MC0, MC22, PC0 and PC22)), highlighting different responses of the two breeds to undernutrition.

    Congenital heart diseases (CHDs) requiring surgical palliation mandate new treatment strategies to optimize long-term outcomes. Despite the mounting evidence of cardiac regeneration, there are no long-term safety studies of autologous cell-based transplantation in the pediatric setting. We aimed to establish a porcine pipeline to evaluate the feasibility and long-term safety of autologous umbilical cord blood mononuclear cells (UCB-MNCs) transplanted into the right ventricle (RV) of juvenile porcine hearts. Piglets were born by caesarean section to enable UCB collection. Upon meeting release criteria, 12 animals were randomized in a double-blinded fashion prior to surgical delivery of test article (n=6) or placebo (n=6). The UCB-MNC (3×10(6) cells per kilogram) or control (dimethyl sulfoxide, 10%) products were injected intramyocardially into the RV under direct visualization. The cohorts were monitored for 3 months after product delivery with assessments of cardiac performance, rhythm, and serial cardiac biochemical markers, followed by terminal necropsy. No mortalities were associated with intramyocardial delivery of UCB-MNCs or placebo. Two animals from the placebo group developed local skin infection after surgery that responded to antibiotic treatment. Electrophysiological assessments revealed no arrhythmias in either group throughout the 3-month study. Two animals in the cell-therapy group had transient, subclinical dysrhythmia in the perioperative period, likely because of an exaggerated response to anesthesia. Overall, this study demonstrated that autologous UCB-MNCs can be safely collected and surgically delivered in a pediatric setting. The safety profile establishes the foundation for cell-based therapy directed at the RV of juvenile hearts and aims to accelerate cell-based therapies toward clinical trials for CHD. ©AlphaMed Press.

    The optimal post-remission treatment for acute myeloid leukemia in first complete remission remains uncertain. Previous comparisons of autologous versus allogeneic hematopoietic cell transplantation noted higher relapse, but lower treatment-related mortality though using bone marrow grafts, with treatment-related mortality of 12-20%. Recognizing lower treatment-related mortality using autologous peripheral blood grafts, in an analysis of registry data from the Center for International Blood and Transplant Research, we compared treatment-related mortality, relapse, leukemia-free survival, and overall survival for patients with acute myeloid leukemia in first complete remission (median ages 36-44, range 19-60) receiving myeloablative HLA-matched sibling donor grafts (bone marrow, n=475 or peripheral blood, n=428) versus autologous peripheral blood (n=230). The 5-year cumulative incidence of treatment-related mortality was 19% (95% confidence interval, 16-23%), 20% (17-24%) and 8% (5-12%) for allogeneic bone marrow, allogeneic peripheral blood and autologous peripheral blood stem cell transplant recipients, respectively. The corresponding figures for 5-year cumulative incidence of relapse were 20% (17-24%), 26% (21-30%) and 45% (38-52%), respectively. At 5 years, leukemia-free survival and overall survival rates were similar: allogeneic bone marrow 61% (56-65%) and 64% (59-68%); allogeneic peripheral blood 54% (49-59%) and 59% (54-64%); autologous peripheral blood 47% (40-54%) and 54% (47-60%); P=0.13 and P=0.19, respectively. In multivariate analysis the incidence of treatment-related mortality was lower after autologous peripheral blood transplantation than after allogeneic bone marrow/peripheral blood transplants [relative risk 0.37 (0.20-0.69); P=0.001], but treatment failure (death or relapse) after autologous peripheral blood was significantly more likely [relative risk 1.32 (1.06-1.64); P=0.011].

    Data reported herein indicate increasing use of hematopoietic cell transplants for persons with blood and bone marrow disorders. Recent trends include increasing use of alternative donors including human leukocyte antigen (HLA)-matched unrelated persons and HLA-matched umbilical cord blood cells, increasing use of blood cell rather than bone marrow grafts, and increasing use of reduced-intensity pretransplant conditioning regimens. Many of these shifts are driven by logistical considerations such as the need for donors in persons without an HLA-identical sibling or expanding use of allotransplants to older persons. Many changes in transplant practices are not supported by results of large randomized trials. More data are needed to critically-assess the impact of these changes.

    Background. Reports on estimated amount of blood loss in maxillofacial surgical procedures will guide clinicians through units of blood required for each procedure. The aim of the study was to assess the amount of blood loss and duration of surgery. Methods. All cases of maxillofacial surgical procedures done under GA in the MFU theatre, from January 2007 to December 2013, were included in the study. Pre- and postoperative haematocrit values, number of units of whole blood requested and used, amount of blood loss, and duration of surgery were recorded. Results. 139 patients were analyzed, of which 75 (54.0%) were males and 64 (46.0%) were females. Fifty-six (40.3%) cases involved soft tissues. Eighty-three cases involved hard tissues. Age range was 2 months to 78 years; mean ± (SD) was 21.3 ± (18.5) years. Isolated unilateral cleft lip had the lowest mean value of estimated blood loss of 10.4 ± 10.8 mLs and also the lowest duration of surgery of 58 (76) minutes. There was no significant relationship between both parameters for cleft lip. Fractures of the mandible had mean blood loss of 352 mLs and duration was 175 min. Conclusion. In this study, there was significant relationship between estimated blood loss and duration of surgery for mandibular and zygomatic complex fractures. PMID:25258698

    Urban children remain disproportionately at risk of having higher blood lead levels than their suburban counterparts. The Westside Cooperative Organization (WESCO), located in Marion County, Indianapolis, Indiana, has a history of children with high blood lead levels as well as high soil lead (Pb) values. This study aims at determining the spatial relationship between soil Pb sources and children's blood lead levels. Soils have been identified as a source of chronic Pb exposure to children, but the spatial scale of the source-recipient relationship is not well characterized. Neighborhood-wide analysis of soil Pb distribution along with a furnace filter technique for sampling interior Pb accumulation for selected homes (n = 7) in the WESCO community was performed. Blood lead levels for children aged 0-5 years during the period 1999-2008 were collected. The study population's mean blood lead levels were higher than national averages across all ages, race, and gender. Non-Hispanic blacks and those individuals in the Wishard advantage program had the highest proportion of elevated blood lead levels. The results show that while there is not a direct relationship between soil Pb and children's blood lead levels at a spatial scale of ~100 m, resuspension of locally sourced soil is occurring based on the interior Pb accumulation. County-wide, the largest predictor of elevated blood lead levels is the location within the urban core. Variation in soil Pb and blood lead levels on the community level is high and not predicted by housing stock age or income. Race is a strong predictor for blood lead levels in the WESCO community.

    Some fetuses with congenital abnormalities of the kidney and urinary tract (CAKUT) have severe renal dysfunction during the prenatal period that can result in oligohydramnios, pulmonary hypoplasia, and death following birth. We hypothesized that cord blood cystatin C (CysC) levels are elevated in neonates who have life-threatening pulmonary hypoplasia and oligohydramnios due to severe renal dysfunction. In this study we compared cord blood CysC levels between a non-survivor group with CAKUT and a survivor group. This was a single-center, retrospective cohort study conducted between January 2007 and December 2015. Eighty-seven neonates who were prenatally diagnosed with CAKUT were included in the study. Cord blood CysC and creatinine levels were compared between the survivor and non-survivor groups at discharge from hospital. Of the 87 neonates enrolled in the study, 67 survived and 21 died before discharge. Median cord blood CysC levels were higher in the non-survivor group than in the survivor group (4.28 vs. 1.96 mg/L, respectively; p < 0.001). Cord blood creatinine levels were not significantly different between the two groups. In patients with oligohydramnios (n = 28), cord blood CysC levels were significantly higher in the non-survivor group than in the survivor group (4.28 vs. 2.23 mg/L, respectively; p = 0.002). In this study population, cord blood CysC levels were significantly higher in the non-survivor group with CAKUT than in the survivor group. These results suggest that cord blood CysC levels may be a good marker of the severity of renal dysfunction at birth.

    In the pathogenesis of Alzheimer's disease (AD) the homeostasis of amyloid precursor protein (APP) processing in the brain is impaired. The expression of the competing proteases ADAM10 (a disintegrin and metalloproteinase 10) and BACE-1 (beta site APP cleaving enzyme 1) is shifted in favor of the A-beta generating enzyme BACE-1. Acitretin--a synthetic retinoid-e.g., has been shown to increase ADAM10 gene expression, resulting in a decreased level of A-beta peptides within the brain of AD model mice and thus is of possible value for AD therapy. A striking challenge in evaluating novel therapeutically applicable drugs is the analysis of their potential to overcome the blood-brain barrier (BBB) for central nervous system targeting. In this study, we established a novel cell-based bio-assay model to test ADAM10-inducing drugs for their ability to cross the BBB. We therefore used primary porcine brain endothelial cells (PBECs) and human neuroblastoma cells (SH-SY5Y) transfected with an ADAM10-promoter luciferase reporter vector in an indirect co-culture system. Acitretin served as a model substance that crosses the BBB and induces ADAM10 expression. We ensured that ADAM10-dependent constitutive APP metabolism in the neuronal cells was unaffected under co-cultivation conditions. Barrier properties established by PBECs were augmented by co-cultivation with SH-SY5Y cells and they remained stable during the treatment with acitretin as demonstrated by electrical resistance measurement and permeability-coefficient determination. As a consequence of transcellular acitretin transport measured by HPLC, the activity of the ADAM10-promoter reporter gene was significantly increased in co-cultured neuronal cells as compared to vehicle-treated controls. In the present study, we provide a new bio-assay system relevant for the study of drug targeting of AD. This bio-assay can easily be adapted to analyze other Alzheimer- or CNS disease-relevant targets in neuronal cells, as their

    Canine visceral leishmaniasis (CVL) is a parasitic disease endemic in many countries, and dogs present as the major natural reservoir of the parasite, Leishmania chagasi (syn. L. infantum). Biomarkers in the canine immune system is an important technique in the course of developing vaccines and treatment strategies against CVL. New methodologies for studying the immune response of dogs during Leishmania infection and after receiving vaccines and treatments against CVL would be useful. In this context, we used peripheral blood mononuclear cells (PBMCs) from healthy dogs to evaluate procedures related to (i) establishment of in vitro conditions of monocytes differentiated into macrophages infected with L. chagasi and (ii) purification procedures of T-cell subsets (CD4(+) and CD8(+)) using microbeads. Our data demonstrated that after 5 days of differentiation, macrophages were able to induce significant phagocytic and microbicidal activity after L. chagasi infection and also showed increased frequency of parasitism and a higher parasite load. Although N-acetyl-β-d-glucosaminidase (NAG) levels presented similar levels of macrophage culture and L. chagasi infection, a progressive decrease in myeloperoxidase (MPO) levels was a hallmark over 5 days of culture. High purity levels (>90%) of CD4 and CD8 T cells were obtained on a magnetic separation column. We concluded that monocytes differentiated into macrophages at 5 days and displayed an intermediate frequency of parasitism and parasite load 72 h after L. chagasi infection. Furthermore, the purification system using canine T-lymphocyte subsets obtained after 5 days of monocyte differentiation proved efficient for CD4 or CD8 T-cell purification (≥90%). The in vitro analysis using L. chagasi-infected macrophages and purified T cells presented a prospective methodology that could be incorporated in CVL vaccine and treatment studies that aim to analyze the microbicidal potential induced by specific CD4(+) and/or CD8(+) T

    Cytarabine (ara-C) is the key drug for treatment of acute myeloid leukemia. Since intracellular cytarabine triphosphate (ara-CTP) is an active metabolite of ara-C, factors that reduce the amount of ara-CTP are known to induce drug resistance. However, these factors do not fully explain the development of resistance to ara-C. The present study was conducted to search for new candidate ara-C resistance factors, including those that are unrelated to ara-CTP production. For this purpose, we newly established five ara-C-resistant leukemic clones from different blood cell lineage leukemic cell lines (HL-60, K562, CEM, THP1 and U937). The resistant subclones were 5-58-fold more ara-C-resistant than their parental counterparts. All of the ara-C-resistant subclones, except for ara-C-resistant CEM cells, displayed alteration of ara-CTP-related factors such as ara-C membrane transport capacity, deoxycytidine kinase activity or cytosolic nucleotidase II activity. To identify new candidate factors, we used two comprehensive approaches: DNA microarray and proteome analyses. The DNA microarray analysis revealed eight genes (C19orf2, HSPA8, LGALS1, POU4F3, PSAP, AKT1, MBC2 and CACNA2D3) that were altered in all five ara-C-resistant lines compared to parental cells. Both proteome and DNA microarray analyses further detected a reduced protein level of stathmin1 in the ara-C-resistant CEM subclone compared to its parental line. Thus, the present findings suggested the involvement of novel multiple mechanisms in mediating the ara-C resistance of leukemic cells. The role of some of these molecules in resistance is still unclear.

    Transfusion of the 'wrong' stem cell product would almost inevitably be lethal, yet assays to confirm the contents of the product bag, except by checking labels and paperwork, are lacking. To increase the likelihood that a product mix-up would be detected in the transplant center, we developed a simple protocol for extended blood typing and hence, for confirmation of donor/product identity, on a tube segment. Apheresis samples were applied, directly or after erythrocyte enrichment, to commercially available blood typing assays, including lateral flow cards and gel agglutination cards. Without sample modification, low hematocrit and high leukocyte count obviated definitive blood typing. Using the most simple erythrocyte enrichment protocol, that is, centrifugation, reliable blood group analysis became possible with either assay. Other, more cumbersome pre-analytical protocols were also successful but provided no advantage. The preferred method was validated on 100 samples; ABD was correctly identified in 100% of cases. Of the other Rh Ags, all except two 'small e', in both cases in heterozygous individuals, were detected; there were no false positives. A simple, inexpensive point-of-care assay for extended blood typing of apheresis products is available, which can reduce the fatal risk of administering the wrong stem cell product.

    To alleviate the shortage of AB plasma, an alternative plasma product, low-titer group A plasma (LTGAP), is now available. The product is indicated for emergency transfusions when the patient's blood group has not been identified. The product's defining anti-B titers vary across institutions, and at our blood center we define <1:100 as low-titer. We created two surveys and emailed them to hospital blood bank managers, supervisors, and medical directors who currently use LTGAP and those that have not ordered it. We calculated the amount of LTGAP that met our <1:100 cutoff. We searched our inventory database to obtain sales of LTGAP, AB, and all other types of plasma in 2014. We learned from the surveys that the product is safe and being used as indicated for only life or limb-threatening emergencies until patient's blood group is known and specific products can be provided. Most common reasons for not using LTGAP were lack of need in non-trauma hospitals and limiting capabilities in blood bank software. Although sales of LTGAP increased by ~5% by end of the first year since introduction, sales of AB plasma remained relatively steady. LTGAP appears to be a safe alternative to group AB plasma for emergency indications. By reviewing our percentage of group A plasma units that meet our low-titer cutoff and the current interest for the product, we can reduce the amount of units we titer each day by ~30% and can readjust that amount if there is increased interest. Besides lack of familiarity and limitations in computer software to incorporate LTGAP, the steady demand for AB plasma can potentially be attributed to trauma centers ordering more AB plasma than needed and potentially wasting it in nonurgent cases to avoid outdating the product and lack of institutional guidelines on when to switch from AB to type-specific plasma resulting in excess AB plasma being transfused.

    The advantageous structural uses of advanced filamentary composites are demonstrated by design, fabrication, and test of three boron-epoxy reinforced C-130 center wing boxes. The advanced development work necessary to support detailed design of a composite reinforced C-130 center wing box was conducted. Activities included the development of a basis for structural design, selection and verification of materials and processes, manufacturing and tooling development, and fabrication and test of full-scale portions of the center wing box. Detailed design drawings, and necessary analytical structural substantiation including static strength, fatigue endurance, flutter, and weight analyses are considered. Some additional component testing was conducted to verify the design for panel buckling, and to evaluate specific local design areas. Development of the cool tool restraint concept was completed, and bonding capabilities were evaluated using full-length skin panel and stringer specimens.

    Dupuytren's contracture (DC) is a chronic fibroproliferative disease of the hand, which is characterized by uncontrolled proliferation of atypical myofibroblasts at the cellular level. We hypothesized that specific areas of the DC tissue are sustaining the cell proliferation and studied the potential molecular determinants that might contribute to the formation of such niches. We studied the expression pattern of cell proliferation marker Ki67, phosphorylated AKT (Ak mouse strain thymoma) kinase, DC-associated growth factors (connective tissue growth factor (CTGF), basic fibroblast growth factor (bFGF), insulin-like growth factor 2 (IGF-2)) and extracellular matrix components (laminins, fibronectin, collagen IV) in DC tissue and normal palmar fascia using immunofluorescence microscopy and quantitative real-time polymerase chain reaction (qPCR). We found that proliferative cells in the DC nodules were concentrated in the immediate vicinity of small blood vessels and localized predominantly in the myofibroblast layer. Correspondingly, the DC-associated blood vessels contained increased levels of phosphorylated AKT, a hallmark of activated growth factor signaling. When studying the expression of potential activators of AKT signaling we found that the expression of bFGF was confined to the endothelium of the small blood vessels, IGF-2 was present uniformly in the DC tissue and CTGF was expressed in the DC-associated sweat gland acini. In addition, the blood vessels in DC nodules contained increased amounts of laminins 511 and 521, which have been previously shown to promote the proliferation and stem cell properties of different cell types. Based on our findings, we propose that in the DC-associated small blood vessels the presence of growth factors in combination with favorable extracellular matrix composition provide a supportive environment for sustained proliferation of myofibroblasts and thus the blood vessels play an important role in DC pathogenesis.

    Background: The implementation of diversion pouches is to minimise the risk of bacterial contamination as the initial blood flow is prevented from entering primary bag collections as it is diverted into a pouch. This study was carried out to determine the prevalence of bacterial contamination in the diversion pouches used during blood collections in the Transfusion Department of Hospital Seberang Jaya, Penang, Malaysia. Methods: BD Bactec™ Fx instrument detection system was performed on 702 samples of 20 mL of diverting blood in diversion pouch. The inocullum volume was 10 mL for both aerobic and anaerobic bottles cultures and incubated for 5 days in the BD Bactec™ Fx instrument. Positive sample was flagged by BD Bactec™ Fx instrument and subculture to identify the species of organism. Results: The results showed that of 702 samples, 12 (1.7%) were contaminated. The bacterial species identified were coagulase negative Staphylococcus, Staphylococcus aureus and Gram positive Bacilli. Conclusion: The results strongly suggest that the usage of diversion pouch is of significant importance in reducing bacterial contamination during blood collection. PMID:25246835

    More than 40000 hematopoietic cell transplants (HCTs) are performed worldwide each year. With improvements in transplant technology, larger numbers of transplant recipients survive free of the disease for which they were transplanted. However, there are late complications that can cause substantial morbidity. Many survivors are no longer under the care of transplant centers, and many community health care providers may be unfamiliar with health matters relevant to HCT. The Center for International Blood and Marrow Transplant Research (CIBMTR), European Group for Blood and Marrow Transplantation (EBMT), and American Society for Bone Marrow Transplantation (ASBMT) have developed these recommendations to offer care providers suggested screening and prevention practices for autologous and allogeneic HCT survivors.

  15. Maintenance of blood flow rate on dialysis with self-centering CentrosFLO catheter: A multicenter prospective study.

    PubMed

    Agarwal, Anil K; Ash, Stephen R

    2016-10-01

    Introduction Chronic central venous catheters (CVC) for dialysis lose patency and deliver lower blood flow over time, often due to fibrous sheathing that covers the lumen tips. The CentrosFLO central venous catheter has a shape that directs the arterial and venous tips away from the walls of the vena cava and right atrium, making sheathing of the tips less likely. Methods A prospective, multicenter, single arm, non-controlled, observational study was conducted at eight sites in the United States. All consenting dialysis patients receiving CentrosFLO catheters through the right or left internal jugular veins were accepted in the study, as long as the catheter was expected to be used for 45 days and was not an over-the-wire replacement for a previous CVC. Data were automatically collected on initial and average dialysis blood flow rate and initial arterial and venous pressures, for up to 26 weeks of dialysis therapy. Findings 75 patients were enrolled. Kaplan-Meier analysis indicated that 87% of patients maintained blood flow rate over 300 mL/min throughout 26 weeks of follow-up. There was no decline in average dialysis blood flow rate and no significant change in hydraulic resistance of the arterial or venous lumens of the catheters during the study. Discussion The CentrosFLO catheter demonstrates long term patency with good flow rates on dialysis, which, by comparison with previous studies, shows a clinically significant improvement in blood flow rate vs. other catheters. Stable hydraulic resistance of the catheter lumens showed no evidence of tip encroachment by fibrous sheaths. © 2016 The Authors.

    Using electronic paramagnetic resonance (EPR), we studied the effect of the peptide cortexin on the content of hemoglobin nitrozyl complexes (Hb-NO-complexes) and other paramagnetic centers (transferrin, methemoglobin) in the blood of rats of Krushynsky-Molodkina line in the experimental hemorrhagic stroke induced by acoustic stress. After the acoustic exposure, the level of Hb-NO-complexes have increased by more than 6 times. The intensity of the EPR signal of the plasma peptide transferrin increased by 1,5 times. The level of blood methemoglobin was also elevated, though not significantly, after the acoustic stress. Cortexin substantially reduces the formation of Hb-NO-complexes and, therefore, the level of nitride oxide while the contents of transferrin and methemoglobin remain intact.

    Noncommunicable diseases such as Hypertension are among the important factors of mortality and morbidity of the elderly people. The family-centered empowerment model (FCEM) has not been performed for elderly people with hypertension. This clinical trial study was carried out on 62 elderly people with hypertension under the coverage of the Lenjan Health Network in 2013. After performing the sampling by using the cluster-randomized method, the samples were divided randomly into the experimental and control groups. For the experimental group, the (FCEM) was implemented based on the four steps. For the control group, it was only implemented the usual care and one training session. Research tools included questionnaires of demographic data, empowerment assessment and a blood pressure-measuring device. The post-test was performed 1 week later. The blood pressure was recorded, and it was followed 1.5 month later again. Statistical tests for data analysis included χ(2)-test, independent t-test, Mann-Whitney, analysis of variance, and SPSS 20. 1 week later and 1.5 month after the intervention, the mean blood pressure was significant in both groups (P < 0.001). also, the difference in the mean score of empowerment dimensions was significant in the experimental group 1 week later and 1.5 month after the intervention (P < 0.001). Implementation of the FCEM for elderly people with hypertension has been possible from a practical point of view, and it has been associated with controlling and improving the blood pressure.

    Subpopulations and Intermediate Outcomes in COPD Study (SPIROMICS) is a multi-center longitudinal, observational study to identify novel phenotypes and biomarkers of chronic obstructive pulmonary disease (COPD). In a subset of 300 subjects enrolled at six clinical centers, we are performing flow cytometric analyses of leukocytes from induced sputum, bronchoalveolar lavage (BAL) and peripheral blood. To minimize several sources of variability, we use a "just-in-time" design that permits immediate staining without pre-fixation of samples, followed by centralized analysis on a single instrument. The Immunophenotyping Core prepares 12-color antibody panels, which are shipped to the six Clinical Centers shortly before study visits. Sputum induction occurs at least two weeks before a bronchoscopy visit, at which time peripheral blood and bronchoalveolar lavage are collected. Immunostaining is performed at each clinical site on the day that the samples are collected. Samples are fixed and express shipped to the Immunophenotyping Core for data acquisition on a single modified LSR II flow cytometer. Results are analyzed using FACS Diva and FloJo software and cross-checked by Core scientists who are blinded to subject data. Thus far, a total of 152 sputum samples and 117 samples of blood and BAL have been returned to the Immunophenotyping Core. Initial quality checks indicate useable data from 126 sputum samples (83%), 106 blood samples (91%) and 91 BAL samples (78%). In all three sample types, we are able to identify and characterize the activation state or subset of multiple leukocyte cell populations (including CD4+ and CD8+ T cells, B cells, monocytes, macrophages, neutrophils and eosinophils), thereby demonstrating the validity of the antibody panel. Our study design, which relies on bi-directional communication between clinical centers and the Core according to a pre-specified protocol, appears to reduce several sources of variability often seen in flow cytometric

    Background Patients on in-center nocturnal hemodialysis therapy typically experience higher interdialytic weight gain (IDWG) than patients on conventional hemodialysis therapy. We determined the safety and effects of decreasing dialysate sodium concentration on IDWG and blood pressure in patients on thrice-weekly in-center nocturnal hemodialysis therapy. Study Design Quality improvement, pre-post intervention. Settings & Participants 15 participants in a single facility. Quality Improvement Plan Participants underwent three 12-week treatment phases, each with different dialysate sodium concentrations, as follows: phase A, 140 mEq/L; phase B, 136 or 134 mEq/L; and phase A+, 140 mEq/L. Participants were blinded to the exact timing of the intervention. Outcomes IDWG, IDWG/dry weight (IDWG%), and blood pressure. Measurements Outcome data were obtained during the last 2 weeks of each phase and compared with mixed models. The fraction of sessions with adverse events (eg, cramping and hypotension) also was reported. Results IDWG, IDWG%, and predialysis systolic blood pressure decreased significantly by 0.6 ± 0.6 kg, 0.6% ± 0.8%, and 8.3 ± 14.9 mm Hg, respectively, in phase B compared with phase A (P < 0.05 for all comparisons). No differences in predialysis diastolic and mean arterial or postdialysis blood pressures were found (P > 0.05 for all comparisons). The proportion of treatments with intradialytic hypotension was low and similar in each phase (P = 0.9). In phase B compared with phase A, predialysis plasma sodium concentration was unchanged (P > 0.05), whereas postdialysis plasma sodium concentration decreased by 3.7 ± 1.9 mEq/L (P < 0.05). Limitations Modest sample size. Conclusion Decreasing dialysate sodium concentrations in patients undergoing thrice-weekly in-center nocturnal hemodialysis resulted in a clinical and statistically significant decrease in IDWG, IDWG%, postdialysis plasma sodium concentration, and predialysis systolic blood pressure without

    Peripheral blood progenitor cells (PBPC) have became the preferred source of stem cells for autologous transplantation because of easier accessibility, rapid engraftment, and lower tumor cell contamination. In pediatric patients is very important to optimize peripheral blood stem cells (PBSC) harvesting to obtain a sufficient number of cells with a reduced number of leukapheresis. In this study we prospectively analyzed data on 43 large volume leukapheresis (LVL) from 20 consecutive low body weight pediatric patients with various malignancies. Patients' mean body weight was 16.6 kg (range, 8.9-32.0 kg), and the median age was 4 years (range, 1-10 y ears). Instead of saline, it was used irradiated and leukoreduced red blood cell (RBC) units to prime the machine in 15 patients weighting 25 kg or less. The median number of LVL was 2 (range, 1-4) and a mean of 5.2 patient's blood volume was processed per session lasting 165 min (range, 118-239). The mean number of CD34+ cells, one day before leukapheresis was 49 mm(-3) (range, 9-219). The PBPC collection yielded 24.7 x 10(8) total nucleated cells/kg (range, 6.2-74.0), 10.7 x 10(6) kg(-1) CD34+ cells (range, 3.6-53.7); 49.8 x 10(4) CFU-GM/kg (range, 6.4-198.1), and 65.6 x 10(4) BFU-E/kg (range, 7.6-198.1). The platelet count decreased significantly after each procedure 39.8 +/- 9.1 x 10(9) mm(-3) (range, 18.000-76.000) (p < 0.001). In conclusion, our data show that LVL for collection of PBPC in low weight pediatric patients is a safe and efficient procedure, but it may expose the patient to the risk of thrombocytopenia.

    The establishment of trauma systems was anticipated to improve overall survival for the severely injured patient. We systematically reviewed the published literature to assess if outcome from severe traumatic injury is improved for patients following the establishment of a trauma system. A systematic literature review of all population-based studies that evaluated trauma system performance was conducted. A qualitative analysis of each study's design and methodology and a meta-analysis was performed to evaluate the evidence to date of trauma system effectiveness. A search of the literature yielded 14 published articles. Trauma systems demonstrated improved odds of survival in 8 of the 14 reports. The overall quality-weighted odds ratio was 0.85 lower mortality following trauma system implementation. The results of the meta-analysis showed a 15% reduction in mortality in favor of the presence of a trauma system. Evaluation of trauma system effectiveness must remain an uncompromising commitment to optimal outcome for the injured patient.

    Areas where selective reinforcement of conventional metallic structure can improve static strength/fatigue endurance at lower weight than would be possible if metal reinforcement were used are discussed. These advantages are now being demonstrated by design, fabrication, and tests of three boron-epoxy reinforced C-130E center wing boxes. This structural component was previously redesigned using an aluminum build-up to meet increased severity of fatigue loadings. Direct comparisons of relative structural weights, manufacturing costs, and producibility can therefore be obtained, and the long-time flight service performance of the composite reinforced structure can be evaluated against the wide background of metal reinforced structure.

    Background A reference interval (RI) for the circulating concentration of anti-dsDNA antibody is essential for clinicians to interpret laboratory results and make clinical decisions. Therefore, we aimed to establish the RI for anti-dsDNA antibody in the Chinese Han population. Methods This study was designed and carried out in accordance with guideline C28-A3, which is proposed by the International Federation of Clinical Chemistry and the Clinical and Laboratory Standards Institute. A total of 2,880 apparently healthy individuals were enrolled using a posteriori sampling. These individuals were recruited from four hospitals, representing the Han populations of north, south, east, and west China. Serum anti-dsDNA antibody levels were measured using the three analytical systems AESKU, EUROIMMUNE, and INOVA, which are the most commonly used systems in China. Individuals were stratified by gender, age, and region, and the RIs were obtained by nonparametric methods. Results Gender-specific RIs for serum anti-dsDNA antibody in the Chinese Han population were established. Conclusion This is the first exploration of the RI for anti-dsDNA antibody in the Chinese Han population. We have established gender-specific RIs for each assay method commonly used in China.

    We aimed to provide updated results for seroprevalence of hepatitis B, hepatitis C viruses while presenting first data for human immunodeficiency virus and syphilis seropositivity amongst blood donors in Adana, Turkey. Screening and confirmatory test results of 62,461 donors were evaluated. HBsAg, anti-HCV, anti-HIV1/2 and syphilis seropositivity was 1.92%, 0.48%, 0.20%, 0.18% respectively, based on screening tests, and 1.66%, 0.05%, 0.003%, 0.10% respectively, according to confirmatory tests. Transfusion-transmitted infections (TTI) was more prevalent in low-educated donors. HBsAg and syphilis seropositivity rates were higher in married subjects. We found that the prevalence of HBV and HCV was significantly decreased in the last two decades in Adana. Importantly, this study provides first data in HIV and syphilis seropositivity rates among blood donors in our region and both HIV and syphilis seroprevalences were found to be low compared to many regions of Turkey. However, considering the fact that increasing number of immigrants may change prevalences and trends of TTI both in Adana and in Turkey, strict monitorization and yearly reporting of TTI rates seem necessary to be able to take proactive measures.

    To better understand the pathophysiology of B cell populations—the precursors of antibody secreting cells—during chronic human immunodeficiency virus (HIV) infection, we examined the phenotype of circulating B cells in newly diagnosed Africans. We found that all African individuals displayed low levels of naive B cells and of memory-type CD27+ B cells, and high levels of differentiated B cells. On the other hand, HIV-infected African patients had a population of germinal center B cells (i.e. CD20+, sIgM-, sIgD+, CD77+, CD138±), which are generally restricted to lymph nodes and do not circulate unless the lymph node architecture is altered. The first observations could be linked to the tropical environment whereas the presence of germinal center B cells may be attributable to chronic exposure to HIV as it is not observed in HIV-negative African controls and HAART treated HIV-infected Europeans. It may impact the management of HIV infection in countries with limited access to HIV drugs and urges consideration for implementation of therapeutic vaccines. PMID:15154608

    Large-scale disasters may disrupt health surveillance systems, depriving health officials and researchers of timely and accurate information needed to assess disaster-related health effects and leading to use of less reliable self-reports of health outcomes. In particular, ascertainment of cancer in a population is ordinarily obtained through linkage of self-reported data with regional cancer registries, but exclusive reliance on these sources following a disaster may result in lengthy delays or loss of critical data. To assess the impact of such reliance, we validated self-reported cancer in a cohort of 59,340 responders and survivors of the World Trade Center disaster against data from 11 state cancer registries (SCRs). We focused on residents of the 11 states with SCRs and on cancers diagnosed from September 11, 2001, to the date of their last survey participation. Medical records were also sought in a subset of 595 self-reported cancer patients who were not recorded in an SCR. Overall sensitivity and specificity of self-reported cancer were 83.9% (95% confidence interval [CI] 81.9, 85.9) and 98.5% (95% CI 98.4, 98.6), respectively. Site-specific sensitivities were highest for pancreatic (90.9%) and testicular (82.4%) cancers and multiple myeloma (84.6%). Compared with enrollees with true-positive reports, enrollees with false-negative reports were more likely to be non-Hispanic black (adjusted odds ratio [aOR] = 1.8, 95% CI 1.2, 2.9) or Asian (aOR=2.2, 95% CI 1.2, 4.1). Among the 595 cases not recorded in an SCR, 13 of 62 (21%) cases confirmed through medical records were reportable to SCRs. Self-report of cancer had relatively high sensitivity among adults exposed to the World Trade Center disaster, suggesting that self-reports of other disaster-related conditions less amenable to external validation may also be reasonably valid.

    To describe validation and performance of epoc, a blood gas analysis point-of-care system, in a live clinical setting. Data were collected for 156 epoc systems over 12 months. Preimplementation precision and correlation studies and postimplementation quality assurance data were collected, including test card, reader, and personal data assistant (PDA) failure rates. The coefficient of variation was clinically acceptable for all analytes. Correlation studies yielded an R(2) from 0.901 (for sodium) to 0.994 (for potassium) with the Nova analyzer and from 0.961 (sodium) to 0.991 (glucose) with the i-STAT. Average test card failure rate was 13%. Of the PDA/reader units, 55% needed repair within 1 year. The analytical performance showed high precision and good correlation with the Nova and i-STAT platforms. Test card and instrument failure rates were higher than that of the i-STAT system.

    Background: Noncommunicable diseases such as Hypertension are among the important factors of mortality and morbidity of the elderly people. The family-centered empowerment model (FCEM) has not been performed for elderly people with hypertension. Settings and Design: This clinical trial study was carried out on 62 elderly people with hypertension under the coverage of the Lenjan Health Network in 2013. After performing the sampling by using the cluster-randomized method, the samples were divided randomly into the experimental and control groups. Methods: For the experimental group, the (FCEM) was implemented based on the four steps. For the control group, it was only implemented the usual care and one training session. Research tools included questionnaires of demographic data, empowerment assessment and a blood pressure-measuring device. The post-test was performed 1 week later. The blood pressure was recorded, and it was followed 1.5 month later again. Statistical Tests: Statistical tests for data analysis included χ2-test, independent t-test, Mann–Whitney, analysis of variance, and SPSS 20. Results: 1 week later and 1.5 month after the intervention, the mean blood pressure was significant in both groups (P < 0.001). also, the difference in the mean score of empowerment dimensions was significant in the experimental group 1 week later and 1.5 month after the intervention (P < 0.001). Conclusion: Implementation of the FCEM for elderly people with hypertension has been possible from a practical point of view, and it has been associated with controlling and improving the blood pressure.

    Prevalence data concerning viral hepatitis and human immunodeficiency virus (HIV) in the general population are usually scarce. We aimed for a large cohort representative of the general population that required little funding. Autologous blood donors are relatively representative of the general population, and are tested for viral hepatitis and HIV in many countries. However, frequently these data are not captured for epidemiologic purposes. We analysed data from well over 35,000 autologous blood donors as recorded in 21 different transfusion centres for anti-hepatitis C virus (HCV), HBsAg and anti-HIV, as well as TPHA if available. We found a lower prevalence of hepatitis B virus and HCV in East vs West Germany, 0.2%vs 0.32% and 0.16%vs 0.32% respectively, which confirms earlier data in smaller cohorts, thus supporting the value of our approach. HIV was too rare to disclose significant differences, 0.01%vs 0.02%. TPHA was higher in East (0.34%) vs West Germany (0.29%) without significant differences. HCV was more frequent in women vs men. Transfusion institutes managing autologous blood donations should be used as a resource for epidemiological data relating to viral hepatitis and HIV, if such testing is performed routinely. This approach generates data relating to the general population with special emphasis on undiagnosed cases.

    Biomarkers can be important predictors of disease severity and progression. The intense exposure to particulates and other toxins from the destruction of the World Trade Center (WTC) overwhelmed the lung’s normal protective barriers. The Fire Department of New York (FDNY) cohort not only had baseline pre-exposure lung function measures but also had serum samples banked soon after their WTC exposure. This well phenotyped group of highly exposed first responders is an ideal cohort for biomarker discovery and eventual validation. Disease progression was heterogeneous in this group in that some individuals subsequently developed abnormal lung function while others recovered. Airflow obstruction predominated in WTC exposed patients who were symptomatic. Multiple independent disease pathways may cause this abnormal FEV1 after irritant exposure. WTC exposure activates one or more of these pathways causing abnormal FEV1 in an individual. Our hypothesis was that serum biomarkers expressed within 6 months after World Trade Center (WTC) exposure reflect active disease pathways and predict subsequent development or protection from abnormal FEV1

    To test the feasibility, acceptability, and effect of a senior center-based behavioral counseling lifestyle intervention on systolic blood pressure (BP). A pre-post design pilot trial of behavioral counseling for therapeutic lifestyle changes in minority elderly people with hypertension. Participants completed baseline visit, Visit 1 (approximately 6 weeks postbaseline), and a final study Visit 2 (approximately 14 weeks postbaseline) within 4 months. The study took place in six community-based senior centers in New York City with 65 seniors (mean age 72.29+/-6.92; 53.8% female; 84.6% African American). Sixty-five minority elderly people. Six weekly and two monthly "booster" group sessions on lifestyle changes to improve BP (e.g., diet, exercise, adherence to prescribed antihypertensive medications). Primary outcome was systolic BP (SBP) measured using an automated BP monitor. Secondary outcomes were diastolic BP (DBP), physical activity, diet, and adherence to prescribed antihypertensive medications. There was a significant reduction in average SBP of 13.0+/-21.1 mmHg for the intervention group (t(25)=3.14, P=.004) and a nonsignificant reduction in mean SBP of 10.6+/-30.0 mmHg for the waitlist control group (t(29)=1.95, P=.06). For the intervention group, adherence improved 26% (t(23)=2.31, P=.03), and vegetable intake improved 23% (t(25)=2.29, P=.03). This senior center-based lifestyle intervention was associated with a significant reduction in SBP and adherence to prescribed antihypertensive medications and diet in the intervention group. Participant retention and group attendance rates suggest that implementing a group-counseling intervention in senior centers is feasible.

    Ankaferd Blood Stopper (ABS), as an herbal complementary medicine, has been approved for the management of clinical hemorrhages in Turkey, including dental interventions. Basic, preclinical and clinical studies disclosed the settings of the topical hemostatic use of ABS. The aim of this study is therefore to assess the efficacy and safety of ABS as an antihemorrhagic agent in the bleedings associated with dental procedures in patients with normal and impaired hemostasis. ABS has been topically applied by homogeneously spraying to the 113 patients during dental interventions within its on-label indications. A median of 0.5 ml (IQR:0.5-1 ml) ABS was administered after tooth extraction with prolonged hemorrhages. After the administration, bleeding stopped in less than 10 seconds in 59 (52.2%) patients, and below 22.5 seconds (IQR: 18, 8-30) in 54 patients (47.8%). A total of 141 procedures were performed in these 113 patients, and nearly 72.5 ml ABS was used with a total cost of 98 €. ABS as a new herbal medicine was found to be an effective method for controlling bleeding related to dental procedures. No patient had wound infection and the healing process appeared to be normal. Topical ABS could be useful for the local hemostasis and wound healing in periodontal surgeries. In this prospective study ABS, for the first time, has demonstrated its potential for being an effective hemostatic agent for the management of bleedings due to dental procedures.

    Reporting of surgical complications is common, but few provide information about the severity and estimate risk factors of complications. If have, but lack of specificity. We retrospectively analyzed data on 2795 gastric cancer patients underwent surgical procedure at the Affiliated Hospital of Qingdao University between June 2007 and June 2012, established multivariate logistic regression model to predictive risk factors related to the postoperative complications according to the Clavien-Dindo classification system. Twenty-four out of 86 variables were identified statistically significant in univariate logistic regression analysis, 11 significant variables entered multivariate analysis were employed to produce the risk model. Liver cirrhosis, diabetes mellitus, Child classification, invasion of neighboring organs, combined resection, introperative transfusion, Billroth II anastomosis of reconstruction, malnutrition, surgical volume of surgeons, operating time and age were independent risk factors for postoperative complications after gastrectomy. Based on logistic regression equation, p=Exp∑BiXi / (1+Exp∑BiXi), multivariate logistic regression predictive model that calculated the risk of postoperative morbidity was developed, p = 1/(1 + e((4.810-1.287X1-0.504X2-0.500X3-0.474X4-0.405X5-0.318X6-0.316X7-0.305X8-0.278X9-0.255X10-0.138X11))). The accuracy, sensitivity and specificity of the model to predict the postoperative complications were 86.7%, 76.2% and 88.6%, respectively. This risk model based on Clavien-Dindo grading severity of complications system and logistic regression analysis can predict severe morbidity specific to an individual patient's risk factors, estimate patients' risks and benefits of gastric surgery as an accurate decision-making tool and may serve as a template for the development of risk models for other surgical groups.

    BACKGROUND AND OBJECTIVES: The US Food and Drug Administration and American Association of Blood Banks approved the type and screen approach in 1980s, long after antibody screen (AS) was introduced in 1950s. The present study omits conventional anti-human globulin (AHG) crossmatch and replaces it with immediate-spin (IS) crossmatch as part of pretransfusion testing in AS-negative patients to study the safety and effectiveness of IS crossmatch in recipients. MATERIALS AND METHODS: This prospective longitudinal study was conducted on over 5000 red cell units transfused to AS-negative patients admitted to the hospital. Pretransfusion testing comprised blood grouping and AS followed by IS crossmatch, at the time of issue of red cell unit. The patients were transfused IS compatible red cell units. AHG crossmatch was performed posttransfusion for all red cell units. Any incompatible AHG crossmatch was followed up as suspected transfusion reaction. RESULTS: A total of 5023 red cell units were transfused to 2402 patients with negative AS. 99.7% IS compatible red cell units were also compatible on posttransfusion AHG crossmatch. Anti-P1 alloantibody was identified in one patient who was transfused two IS crossmatch compatible units but later both units were incompatible on AHG crossmatch. There was no clinical or serological sign of hemolysis in the patient. CONCLUSION: In AS-negative patients, IS crossmatch is as safe as conventional AHG crossmatch and can, therefore, replace conventional AHG crossmatch protocol. PMID:28316439

Our hypothesis was that serum biomarkers expressed within 6 months after WTC exposure reflect active disease pathways and predict subsequent development or protection from abnormal FEV1 below the lower limit of normal known as WTC-Lung Injury (WTC-LI). We utilized a nested case-cohort control design of previously healthy never smokers who sought subspecialty pulmonary evaluation to explore predictive biomarkers of WTC-LI. We have identified biomarkers of inflammation, metabolic derangement, protease/antiprotease balance, and vascular injury expressed in serum within 6 months of WTC exposure that were predictive of their FEV1 up to 7 years after their WTC exposure. Predicting future risk of airway injury after particulate exposures can focus monitoring and early treatment on a subset of patients in greatest need of these services.

    Although transplant practices have changed over the last decades, no information is available on trends in incidence and outcome of chronic graft-versus-host disease (cGVHD) over time. This study used the central database of the Center for International Blood and Marrow Transplant Research (CIBMTR) to describe time trends for cGVHD incidence, nonrelapse mortality, and risk factors for cGVHD. The 12-year period was divided into 3 intervals, 1995 to 1999, 2000 to 2003, and 2004 to 2007, and included 26,563 patients with acute leukemia, chronic myeloid leukemia, and myelodysplastic syndrome. Multivariate analysis showed an increased incidence of cGVHD in more recent years (odds ratio = 1.19, P < .0001), and this trend was still seen when adjusting for donor type, graft type, or conditioning intensity. In patients with cGVHD, nonrelapse mortality has decreased over time, but at 5 years there were no significant differences among different time periods. Risk factors for cGVHD were in line with previous studies. This is the first comprehensive characterization of the trends in cGVHD incidence and underscores the mounting need for addressing this major late complication of transplantation in future research.

    Trends in utilization and outcomes after autologous or allogeneic hematopoietic cell transplantation (HCT) for Burkitt Lymphoma (BL) were analyzed in 241 recipients reported to the Center for International Blood and Marrow Transplant Research (CIBMTR) between 1985 and 2007. The autologous HCT cohort had a higher proportion with chemotherapy sensitive disease, peripheral blood grafts and HCT in first complete remission (CR1). The use of autologous HCT has declined over time with only 19% done after 2001. Overall survival (OS) at 5 years for the autologous cohort was 83% for those in CR1, and 31% for non-CR1 recipients. Corresponding progression free survival (PFS) was 78% and 27%, respectively. After allogeneic HCT, OS at 5 years was 53% and 20% for the CR1 and non-CR1 cohorts while PFS was 50% and 19%, respectively. The most common cause of death was progressive lymphoma. Allogeneic HCT performed in a higher risk subset (per NCCN guidelines) resulted in a 5 year PFS of 27%. Autologous HCT, resulted in a 5 year PFS of 44% in those transplanted in second CR.

    Traditional Chinese medicine (TCM) has a long history in the treatment of psoriasis vulgaris. We aimed to evaluate the clinical efficacy and safety of Chinese herbal Pulian ointment in treating psoriasis vulgaris of blood-heat syndrome. A multicenter, randomized, double-blind, placebo-controlled trial was conducted. Participants with psoriasis vulgaris of blood-heat syndrome were blinded and randomized to receive Pulian ointment or placebo ointment twice daily for 4 weeks, with follow-up 8 weeks after treatment. Psoriasis Area Severity Index (PASI) scores, severity of each symptom and area of skin lesion and quality of life were assessed at baseline, 2 weeks, and 4 weeks. Adverse events were recorded during the study. SAS 9.4 software and SPSS 17.0 software was applied for data analysis. A total of 300 participants with psoriasis vulgaris of blood-heat syndrome were assessed for eligibility, and 294 were randomly assigned to the Pulian ointment and placebo group from six study centers. Full analysis set (FAS): after 4 weeks of treatment, there were significant differences between groups in PASI score and the separate score of skin lesion area, favoring Pulian ointment group (P < 0.05). However, no significant differences were observed in scores of scaling, erythema and induration/thickness (P > 0.05). Per protocol set (PPS): There was no statistically significant difference in PASI score and separate score of each symptom and area of skin lesion between two groups (P > 0.05). Quality of life measured by Hamilton Anxiety Rating Scale (HAMA) and 36-Item Short Form Health Survey (SF-36) improved after treatment in both groups, but there was no significant difference between the two groups (P > 0.05). After being followed up for 8 weeks, the total relapse rates of the Pulian Ointment group and placebo group were 5.88 and 8.45%, respectively, and the difference was not statistically significant between the two groups (P > 0.05).

    Brucella spp. are facultative intracellular bacteria that infect humans and animals. In this study, the loop-mediated isothermal amplification (LAMP) was used to detect the Brucella-specific gene omp25. Reaction conditions were optimized as temperature 65°C, reaction time 60 min, Mg(2+) concentration 8.0 mmol/L, polymerase content Bst DNA, 0.5 μL, deoxyribonucleotide concentration 1.6 mmol/L, and inner/outer primer ratio 1:8. The LAMP method was evaluated with 4 Brucella species and 29 non-Brucella bacteria species. Positive reactions were observed on all the 4 Brucella species but not on any non-Brucella species. The limit of detection of the LAMP method was 3.81 CFU Brucella spp. Using the LAMP method, 7 of 110 raw milk samples and 5 of 59 sheep blood samples were detected positive of Brucella spp. Results indicated that LAMP is a fast, specific, sensitive, inexpensive, and suitable method for diagnosis of Brucella spp. infection.

    In this study, we investigated the gene regulatory network that governs formation of the Zona limitans intrathalamica (ZLI), a signaling center that secretes Sonic Hedgehog (Shh) to control the growth and regionalization of the caudal forebrain. Using loss- and gain-of-function, explants and grafting experiments in amphibians, we demonstrate that barhl2 acts downstream of otx2 and together with the iroquois (irx)-3 gene in establishment of the ZLI compartment initiated by Shh influence. We find that the presumptive (pre)-ZLI domain expresses barhl2, otx2 and irx3, whereas the thalamus territory caudally bordering the pre-ZLI expresses barhl2, otx2 and irx1/2 and early on irx3. We demonstrate that Barhl2 activity is required for determination of the ZLI and thalamus fates and that within the p2 alar plate the ratio of Irx3 to Irx1/2 contributes to ZLI specification and size determination. We show that when continuously exposed to Shh, neuroepithelial cells coexpressing barhl2, otx2 and irx3 acquire two characteristics of the ZLI compartment-the competence to express shh and the ability to segregate from anterior neural plate cells. In contrast, neuroepithelial cells expressing barhl2, otx2 and irx1/2, are not competent to express shh. Noteworthy in explants, under Shh influence, ZLI-like cells segregate from thalamic-like cells. Our study establishes that Barhl2 activity plays a key role in p2 alar plate patterning, specifically ZLI formation, and provides new insights on establishment of the signaling center of the caudal forebrain.

    Despite the devastating collapse of three vulture populations on the Asian subcontinent as a result of their exposure to diclofenac, there is little available information on the normal physiology of many vulture species, including the African White-backed Vulture (Gyps africanus). Such information is needed to fully understand mechanisms for toxicity and to identify and prevent future health problems. The aim of this study was to establish baseline parameters for hematologic and selected serum chemistry parameters for this model species for further studies into the toxicity of diclofenac. Captive nonreleasable and wild African White-backed Vultures were used to determine reference values. For hematology, erythrocyte counts, hemoglobin concentration, hematocrit, packed cell volume, mean corpuscular volume, mean corpuscular hemoglobin concentration, and total and differential leukocyte counts were measured. Chemical analytes measured included sodium, potassium, calcium, albumin, and globulin concentrations, aspartate aminotransferase, creatine kinase, and alanine aminotransferase activities. Uric acid and urea concentrations and the urea:uric acid ratio also were evaluated. Values are presented as means, standard deviations, and reference intervals. The serum chemistry parameters selected may provide a starting point for the evaluation of changes in renal and hepatic function; these organ systems are most severely affected by diclofenac. Results were also compared with values reported for G. africanus nestlings, and from these results it is evident that the clinical pathologic parameters are age related. This indicates that the use of nestling values for the evaluation of clinical pathologic findings in adults may be unreliable and could lead to incorrect assumptions.

    This Center for International Blood and Marrow Transplant Research report describes the use of hematopoietic stem cell transplantation (HSCT) in pediatric patients with cancer, 4408 undergoing allogeneic (allo) and3076 undergoing autologous (auto) HSCT in the United States between 2008 and 2014. In both settings, there was a greater proportion of boys (n = 4327; 57%), children < 10 years of age (n = 4412; 59%), whites (n = 5787; 77%), and children with a performance score ≥ 90% at HSCT (n = 6187; 83%). Leukemia was the most common indication for an allo-transplant (n = 4170; 94%), and among these, acute lymphoblastic leukemia in second complete remission (n = 829; 20%) and acute myeloid leukemia in first complete remission (n = 800; 19%) werethe most common. The most frequently used donor relation, stem cell sources, and HLA match were unrelated donor (n = 2933; 67%), bone marrow (n = 2378; 54%), and matched at 8/8 HLA antigens (n = 1098; 37%) respectively. Most allo-transplants used myeloablative conditioning (n = 4070; 92%) and calcineurin inhibitors and methotrexate (n = 2245; 51%) for acute graft-versus-host disease prophylaxis. Neuroblastoma was the most common primary neoplasm for an auto-transplant (n = 1338; 44%). Tandem auto-transplants for neuroblastoma declined after 2012 (40% in 2011, 25% in 2012, and 8% in 2014), whereas tandem auto-transplants increased for brain tumors (57% in 2008 and 77% in 2014). Allo-transplants from relatives other than HLA-identical siblings doubled between 2008 and 2014 (3% in 2008 and 6% in 2014). These trends will be monitored in future reports of transplant practices in the United States. Copyright © 2017 The American Society for Blood and Marrow Transplantation. Published by Elsevier Inc.

    Population-based studies are important to address emerging issues in health disparities among populations. The Partnership between the Moffitt Cancer Center (MCC) in Florida and the Ponce School of Medicine and Health Sciences (PSMHS) in Puerto Rico (the PSMHS-MCC Partnership) was developed to facilitate high-quality research, training, and community outreach focusing on the Puerto Rican population in the island and in the mainland, with funding from the National Cancer Institute. We report here the establishment of a Tissue Biobank at PSMHS, modeled after the MCC tissue biorepository, to support translational research projects on this minority population. This facility, the Puerto Rico Tissue Biobank, was jointly developed by a team of basic and clinical scientists from both institutions in close collaboration with the administrators and clinical faculty of the tissue accrual sites. The efforts required and challenges that needed to be overcome to establish the first functional, centralized cancer-related biobank in Puerto Rico, and to ensure that it continuously evolves to address new needs of this underserved Hispanic population, are described. As a result of the collaborative efforts between PSMHS and MCC, a tissue procurement algorithm was successfully established to acquire, process, store, and conduct pathological analyses of cancer-related biospecimens and their associated clinical-pathological data from Puerto Rican patients with cancer recruited at a tertiary hospital setting. All protocols in place are in accordance with standard operational procedures that ensure high quality of biological materials and patient confidentiality. The processes described here provide a model that can be applied to achieve the establishment of a functional biobank in similar settings. PMID:24836632

  16. Blood donor well-being: a primary responsibility of blood collection agencies.

    PubMed

    Reiss, Robert F

    2011-01-01

    Current FDA regulations and AABB standards do not adequately protect the well-being of blood donors. Several practices have adverse consequences for donors, including: elevated incidence of donation related reactions and injuries, iron deficiency anemia in premenopausal women, and inadequate counseling of donors to obtain medical follow-up for health risks identified during pre-donation health screening. These practices can be improved without impacting negatively on the national blood supply. In addition to revising current blood collection operations, blood centers should explore the feasibility of establishing expanded donor health screening programs and determining their effectiveness in improving donor health, donor recruitment, and donor retention.

    Background: Randomized controlled studies have investigated the short-term effect of soy product intake on blood pressure (BP) in normotensive people. To our knowledge, no prospective studies exist on the effect of habitual intake of fermented soy products, separate from total soy products, on BP in the general population.Objective: We examined the association between the habitual intake of soy products, including fermented soy products, and the development of high BP during a 5-y period among participants in a population-based prospective cohort study in Japan.Methods: The study included normotensive participants aged 40-69 y at baseline (926 men and 3239 women) who completed 2 questionnaires and whose BP was measured at the baseline survey between 1993 and 1994 and the 5-y follow-up in the Japan Public Health Center-Based Prospective Study Cohort II. The intake of soy products was assessed with a food-frequency questionnaire. High BP was defined as systolic blood pressure ≥130 mm Hg, diastolic blood pressure ≥85 mm Hg, or antihypertensive medication use. ORs and 95% CIs of high BP by frequency of soy products (miso, natto, and tofu) consumption, intake of total and fermented soy products, and intake of isoflavones from total and fermented soy products were estimated with the use of multiple logistic regression analysis.Results: Multivariable-adjusted ORs of high BP for the highest compared with the lowest tertile of total and fermented soy product intake were 1.03 (95% CI: 0.84, 1.25; P-trend = 0.786) and 0.72 (95% CI: 0.56, 0.92; P-trend = 0.009), respectively. The frequency of nonfermented soy product (tofu) intake was not associated with the development of high BP (P-trend = 0.597).Conclusions: The intake of fermented soy products, but not total or nonfermented soy products, was inversely associated with developing high BP in men and women with normal BP. © 2017 American Society for Nutrition.

    Purpose Autologous hematopoietic cell transplantation, or autotransplantation, is effective in light-chain amyloidosis (AL), but it is associated with a high risk of early mortality (EM). In a multicenter randomized comparison against oral chemotherapy, autotransplantation was associated with 24% EM. We analyzed trends in outcomes after autologous hematopoietic cell transplantation for AL in North America. Patients and Methods Between 1995 and 2012, 1,536 patients with AL who underwent autotransplantation at 134 centers were identified in the Center for International Blood and Marrow Transplant Research database. EM and overall survival (OS) were analyzed in three time cohorts: 1995 to 2000 (n = 140), 2001 to 2006 (n = 596), and 2007 to 2012 (n = 800). Hematologic and renal responses and factors associated with EM, relapse and/or progression, progression-free survival and OS were analyzed in more recent subgroups from 2001 to 2006 (n = 197) and from 2007 to 2012 (n = 157). Results Mortality at 30 and 100 days progressively declined over successive time periods from 11% and 20%, respectively, in 1995 to 2000 to 5% and 11%, respectively, in 2001 to 2006, and to 3% and 5%, respectively, in 2007 to 2012. Correspondingly, 5-year OS improved from 55% in 1995 to 2000 to 61% in 2001 to 2006 and to 77% in 2007 to 2012. Hematologic response to transplantation improved in the latest cohort. Renal response rate was 32%. Centers performing more than four AL transplantations per year had superior survival outcomes. In the multivariable analysis, cardiac AL was associated with high EM and inferior progression-free survival and OS. Autotransplantation in 2007 to 2012 and use of higher dosages of melphalan were associated with a lowered relapse risk. A Karnofsky score less than 80 and creatinine levels 2 mg/m2 or greater were associated with worsened OS. Conclusion Post-transplantation survival in AL has improved, with a dramatic reduction in early post-transplantation mortality

    The first two books on behavior analysis (Skinner, 1938; Keller & Schoenfeld, 1950) had chapter-length coverage of motivation. The next generation of texts also had chapters on the topic, but by the late 1960s it was no longer being given much treatment in the behavior-analytic literature. The present failure to deal with the topic leaves a gap in our understanding of operant functional relations. A partial solution is to reintroduce the concept of the establishing operation, defined as an environmental event, operation, or stimulus condition that affects an organism by momentarily altering (a) the reinforcing effectiveness of other events and (b) the frequency of occurrence of that part of the organism's repertoire relevant to those events as consequences. Discriminative and motivative variables can be distinguished as follows: The former are related to the differential availability of an effective form of reinforcement given a particular type of behavior; the latter are related to the differential reinforcing effectiveness of environmental events. An important distinction can also be made between unconditioned establishing operations (UEOs), such as food deprivation and painful stimulation, and conditioned establishing operations (CEOs) that depend on the learning history of the organism. One type of CEO is a stimulus that has simply been paired with a UEO and as a result may take on some of the motivative properties of that UEO. The warning stimulus in avoidance procedures is another important type of CEO referred to as reflexive because it establishes its own termination as a form of reinforcement and evokes the behavior that has accomplished such termination. Another CEO is closely related to the concept of conditional conditioned reinforcement and is referred to as a transitive CEO, because it establishes some other stimulus as a form of effective reinforcement and evokes the behavior that has produced that other stimulus.

    A consensus meeting of representatives of 16 Latin American and Caribbean countries and the REAL-PANLAR group met in the city of Bogota to provide recommendations for improving quality of care of patients with rheumatoid arthritis (RA) in Latin America, defining a minimum standards of care and the concept of center of excellence in RA. Twenty-two rheumatologists from 16 Latin American countries with a special interest in quality of care in RA participated in the consensus meeting. Two RA Colombian patients and 2 health care excellence advisors were also invited to the meeting. A RAND-modified Delphi procedure of 5 steps was applied to define categories of centers of excellence. During a 1-day meeting, working groups were created in order to discuss and validate the minimum quality-of-care standards for the 3 proposed types of centers of excellence in RA. Positive votes from at least 60% of the attending leaders were required for the approval of each standard. Twenty-two opinion leaders from the PANLAR countries and the REAL-PANLAR group participated in the discussion and definition of the standards. One hundred percent of the participants agreed with setting up centers of excellence in RA throughout Latin America. Three types of centers of excellence and its criteria were defined, according to indicators of structure, processes, and outcomes: standard, optimal, and model. The standard level should have basic structure and process indicators, the intermediate or optimal level should accomplish more structure and process indicators, and model level should also fulfill outcome indicators and patient experience. This is the first Latin American effort to standardize and harmonize the treatment provided to RA patients and to establish centers of excellence that would offer to RA patients acceptable clinical results and high levels of safety.

    To investigate the impact of the establishment of chest pain center (CPC) model based on the pre-hospital real-time tele-12-lead electrocardiogram on the door-to-balloon (D-to-B) time and short-term outcome after primary percutaneous coronary intervention (PPCI) of patients with ST-segment elevated myocardial infarction (STEMI). A regular CPC was established with pre-hospital transmitted real-time 12-lead electrocardiogram system for pre-hospital diagnosis of STEMI and enabled the STEMI patients to bypass the emergency room and directly treated in the catheter lab to shorten the D-to-B time. The mean D-to-B time, the short-term outcome and medical costs were compared in PPCI patients before (93 cases, group A) and after (149 cases, group B) the establishment of CPC. After the establishment of CPC, the annual mean D-to-B time was significantly shortened [(127 ± 79) min in group A vs.(72 ± 23 )min in group B, P < 0.01], the shortest monthly mean D-to-B time was remarkably reduced in group B than in group A [(56 ± 11) min vs. (73 ± 14) min, P < 0.01]. The annual ratio of D-to-B below 90 minutes was significantly increased from 62.4% (58/93) in group A to 91.9% (137/149) in group B (P < 0.05) . The in-hospital mortality rate tended to be lower and the incidence of heart failure during hospitalization was significantly reduced in group B compared with group A [3.4% (5/149) vs. 6.5% (6/93), P > 0.05; 14.1% (21/149) vs. 24.7% (23/93), P < 0.05]. The length of hospital stay was slightly shortened from (8.98 ± 4.89) days to (7.79 ± 5.43) days (P > 0.05). Corrected mean medical cost went down by 9.4% (P < 0.05). The establishment of CPC may significantly shorten the D-to-B time, improve the short-term outcome and reduce the hospitalization cost for PPCI patients with STEMI.

    Radical Prostatectomy (RP) has been traditionally associated with significant operative blood loss and high risk of transfusion. However, over the last few years, centers of excellence have reported less bleeding and transfusion. To verify and document changes in the epidemiology of bleeding and transfusion of men electing RP, we undertook an analysis of such cases in the Department of Defense (DoD) Center for Prostate Disease Research (CPDR) Multicenter Research Database. Using the Department of Defense Center for Prostate Disease Research (CPDR) Multicenter National Research Database, a query of all RPs performed between January 1, 1985 and December 31, 2000 was conducted revealing 2918 cases with blood-loss data available for analysis from nine hospital sites. These cases were analyzed over time (calendar year) and changes in the characteristics of the patients, disease severity, and surgical results were compared with estimated blood loss (EBL) and transfusion data. Among the 2918 evaluable men, 2399 (82%) underwent a retropubic RP, 97% had clinical T1-2 disease, and 77% had a PSA level > or =10.0 ng/mL. Overall median operation time was 3.8 h, and EBL was 1000 cc. Examining trends over time, there was a dramatic decline in median operative time, EBL, and transfusion rate. In multiple linear regression analysis, operative time, operative approach, surgery year, lymphadenectomy status, and neoadjuvant hormonal therapy were significant predictor of EBL. Blood loss difference between retropubic and perineal RP became insignificant in the latter years. Radical prostatectomy is being performed more commonly on men with earlier stage disease in the PSA-Era. The operation is now performed more rapidly with less blood loss and fewer transfusion requirements. In a broad practice experience represented here, autologous blood donation would appear to be unnecessary for the majority of men and the blood loss advantage traditionally associated with perineal RP is no longer

    Background Studies on health-related quality of life are based on the increasingly evident need for medical care not to be limited to preventing death, but to focus instead on the value of health. Objective This study aimed to measure the health-related quality of life in hemophilia, using the Hemophilia- Specific Quality of Life (Haem-A-QoL) questionnaire and describe the socioeconomic characteristics and health conditions of these patients. Methods The Brazilian version of the Hemophilia-Specific Quality of Life questionnaire was administered to hemophiliac adults, treated in an on-demand regime at the Juiz de Fora Regional Blood Center - HEMOMINAS Foundation. The patients were interviewed about demographic and socioeconomic data and their understanding of the questionnaire. Clinical data were collected from medical records. The Mann-Whitney U test was used for statistical analysis. The level of significance was set for p-values < 0.05. Statistical analysis was performed using the Statistical Package for the Social Sciences (SPSS, version 15.0). Results Thirty-nine patients were evaluated. The mean age was 36.8 years. 84.6% had hemophilia A; 20.5% of the patients had hemophilia classified as mild, 41% as moderate and 38.5% as severe. The records of 10.5% of the patients registered seropositivity for anti-HIV and 57.9% for anti-HCV. Target joints were detected in 69.2%. The mean total Hemophilia-Specific Quality of Life score was 35.55. 'Sports and leisure'and 'Physical health'were the most impaired dimensions and the dimension 'Relationship and partners'was the least impaired. The Hemophilia-Specific Quality of Life scores showed good discriminant validity for hemophilia severity (p-value = 0.001), HIV-infection (p-value = 0.02), HCV-infection (p-value = 0.01) and the presence of target joints (p-value < 0.001).

    Survivors of hematopoietic cell transplantation (HCT) are at risk of subsequent solid tumors, including central nervous system (CNS) tumors. The risk of CNS tumors after HCT in pediatric HCT recipients is not known. We evaluated the incidence and risk factors for CNS tumors in pediatric recipients of allogeneic HCT reported to the Center for International Blood and Marrow Transplant Research between 1976 and 2008. A case control design was used. There were no CNS tumors in the nonmalignant cohort (n = 4543) or in those undergoing HCT for solid tumors (n = 26). There were 59 CNS tumors in 8720 patients transplanted for hematologic malignancies. In comparison with the general population, pediatric HCT recipients with hematologic malignancies had a 33 times higher than expected rate of CNS tumors (95% confidence interval, 22.98 to 45.77; P < .0001). The cumulative incidence of subsequent CNS tumors was 1.29% (95% confidence interval .87 to 1.87) at 20 years after HCT. Significant risk factors in the entire cohort were having an unrelated donor (HR, 3.35; P = .0002) and CNS disease before HCT for both acute lymphoblastic leukemia (HR, 8.21; P = .0003) and acute myeloid leukemia (HR, 6.21; P = .0174). Analysis of the matched cohort showed having an unrelated donor transplant (HR, 4.79; P = .0037), CNS disease before HCT (HR, 7.67; P = .0064), and radiotherapy exposure before conditioning (HR, 3.7; P = .0234) to be significant risk factors. Chronic graft-versus-host disease was associated with a lower risk (HR, .29; P = .0143). Survivors of HCT for nonmalignant diseases did not show an increased incidence of CNS tumors, whereas survivors of hematologic malignancies have a markedly increased incidence of CNS tumors that warrants lifelong surveillance.

    Veno-occlusive disease (VOD) is an early and serious complication of hematopoietic cell transplantation (HCT) that is associated with inferior survival, particularly when it is complicated by multiorgan failure (severe VOD). We evaluated the efficacy of defibrotide in the treatment of severe VOD using observational data from the Center for International Blood and Marrow Transplant Research (CIBMTR). Eight thousand three hundred forty-one patients treated by HCT between 2008 and 2011 were identified from the CIBMTR clinical database; 3.2% met criteria for VOD and 1.2% met criteria for severe VOD. Patients with a diagnosis of VOD as reported to the CIBMTR by their transplanting centers, who had no prior history of cirrhosis, and who had a maximum total bilirubin level > 2.0 mg/dL by day +100 post-HCT were selected for study. Severe VOD was defined as VOD occurring in the setting of renal impairment requiring dialysis or any noninfectious pulmonary abnormality. Patients with severe VOD were divided into 2 groups for analysis: those treated with defibrotide (n = 41) and those not treated with defibrotide (n = 55). Patients in the nondefibrotide group were older, were more likely to be male, were more likely to have a history of previous fungal infection, and had a higher proportion of clinically significant pre-existing disease or organ impairment. Survival rate at day +100 was 39% (95% CI, 24.8% to 54.3%) in patients receiving defibrotide and 30.9% (95% CI, 19.5% to 43.6%) in those not receiving defibrotide. Resolution rate of VOD at day +100 was 51% in the defibrotide group and 29% in the nondefibrotide group (difference, 22.1%; 95% CI, 2.6% to 42%). The results of our study are consistent with previously reported experiences with defibrotide, confirm the poor outcome of this syndrome, and suggest defibrotide is effective in the treatment of severe VOD.

    Detection of antigen-specific CD4+ T cells is central to the study of many human infectious diseases, vaccines, and autoimmune diseases. However, such cells are generally rare and heterogeneous in their cytokine profiles. Identification of antigen-specific germinal center (GC) T follicular helper (Tfh) cells by cytokine production has been particularly problematic. The function of a GC Tfh cell is to selectively help adjacent GC B cells via cognate interaction; thus, GC Tfh cells may be ‘stingy’ cytokine producers, fundamentally different than Th1 or Th17 cells in the quantities of cytokines produced. Conventional identification of antigen-specific cells by intracellular cytokine staining (ICS) relies on the ability of the CD4+ T cell to generate substantial amounts of cytokine. To address this problem, we have developed a cytokine-independent activation induced marker (AIM) methodology to identify antigen-specific GC Tfh cells in human lymphoid tissue. Whereas Group A Streptococcus (Strep)-specific GC Tfh cells produced minimal detectable cytokines by ICS, the AIM method identified 85-fold more antigen-specific GC Tfh cells. Intriguingly, these GC Tfh cells consistently expressed programmed death ligand 1 (PD-L1) upon activation. AIM also detected non-Tfh cells in lymphoid tissue. As such, we applied AIM for identification of rare antigen-specific CD4+ T cells in human peripheral blood. Dengue-, tuberculosis-, and pertussis-vaccine-specific CD4+ T cells were readily detectable by AIM. In sum, cytokine assays missed 98% of antigen-specific human GC Tfh cells, reflecting the biology of these cells, which could instead be sensitively identified by co-expression of TCR-dependent activation markers.

    Patients with FMS like tyrosine kinase 3 (FLT3)-mutated acute myeloid leukemia (AML) have a poor prognosis and are referred for early allogeneic hematopoietic stem cell transplantation (HCT). Data from the Center for International Blood and Marrow Transplant Research (CIBMTR) were used to evaluate 511 adult patients with de novo AML who underwent HCT during 2008 through 2011 to determine whether FLT3 mutations had an impact on HCT outcomes. In total, 158 patients (31%) had FLT3 mutations. Univariate and multivariate analyses revealed an increased risk of relapse at 3 years in the FLT3 mutated group compared with the wild-type (WT) group (38% [95% confidence interval (CI), 30%-45%] vs 28% [95% CI, 24%-33%]; P = .04; relative risk, 1.60 [95% CI, 1.15-2.22]; P = .0048). However, FLT3 mutation status was not significantly associated with nonrelapse mortality, leukemia-free survival, or overall survival. Although more patients in the FLT3 mutated group died from relapsed primary disease compared with those in the WT group (60% vs 46%), the 3-year overall survival rate was comparable for the 2 groups (mutated group: 49%; 95% CI, 40%-57%; WT group: 55%, 95% CI, 50%-60%; P = .20). The current data indicate that FLT3 mutation status did not adversely impact overall survival after HCT, and about 50% of patients with this mutation who underwent HCT were long-term survivors.

    Background Here, we report application of high-throughput near-full-length genome (NFLG) and partial HIV-1 proviral genome deep sequencing to characterize HIV in recently infected blood donors at four major blood centers in Brazil. Study Design and Methods From 2007-2011, 341 HIV+ blood donors from 4 blood centers were recruited to participate in a case control study to identify HIV risk factors and motivations to donate. Forty-seven (17 from São Paulo [SP], 8 from Minas Gerais [MG], 11 from Pernambuco [PE] and 11 from Rio de Janeiro [RJ]) were classified as recently infected based on testing by less-sensitive enzyme immunoassays. Five overlapping amplicons spanning the HIV genome were PCR amplified from peripheral blood mononuclear cells (PBMCs). The amplicons were molecularly bar-coded, pooled, and sequenced by an Illumina paired-end protocol. Results Of the 47 recently infected donor samples studied, 39 (82.9%) NFLGs and 6 (12.7%) partial fragments were de novo assembled into contiguous sequences and successfully subtyped. Subtype B was the only non-recombinant virus identified in this study and accounted for 62.2% (28/45) of samples. The remaining 37.8% (17/45) of samples showed various patterns of subtype discordance in different regions of HIV-1 genomes, indicating 2- 4 circulating recombinant subtypes derived from clades B, F and C. Fourteen samples (31.1%) from this study harbored drug resistance mutations, indicating higher rate of drug resistance among Brazilian blood donors. Conclusion Our findings revealed a high proportion of HIV-1 recombinants among recently infected blood donors in Brazil which has implications for future blood screening, diagnosis, therapy and vaccine development.

    The Minimally Invasive Surgical Trainer-Virtual Reality (MIST-VR) has been well validated as a training device for laparoscopic skills. It has been demonstrated that training to a level of proficiency on the simulator significantly improves operating room performance of laparoscopic cholecystectomy. The purpose of this project was to obtain a national standard of proficiency using the MIST-VR based on the performance of experienced laparoscopic surgeons. Surgeons attending the Society of American Gastrointestinal Endoscopic Surgeons (SAGES) 2004 Annual Scientific Meeting who had performed more than 100 laparoscopic procedures volunteered to participate. All the subjects completed a demographic questionnaire assessing laparoscopic and MIST-VR experience in the learning center of the SAGES 2004 meeting. Each subject performed two consecutive trials of the MIST-VR Core Skills 1 program at the medium setting. Each trial involved six basic tasks of increasing difficulty: acquire place (AP), transfer place (TP), traversal (TV), withdrawal insert (WI), diathermy task (DT), and manipulate diathermy (MD). Trial 1 was considered a "warm-up," and trial 2 functioned as the test trial proper. Subject performance was scored for time, errors, and economy of instrument movement for each task, and a cumulative total score was calculated. Trial 2 data are expressed as mean time in seconds in Table 2. Proficiency levels for laparoscopic skills have now been established on a national scale by experienced laparoscopic surgeons using the MIST-VR simulator. Residency programs, training centers, and practicing surgeons can now use these data as guidelines for performance criterion during MIST-VR skills training.

    The Michigan Geological Repository for Research and Education (MGRRE), part of the Department of Geosciences at Western Michigan University (WMU) at Kalamazoo, Michigan, established MichCarb—a geological carbon sequestration resource center by: • Archiving and maintaining a current reference collection of carbon sequestration published literature • Developing statewide and site-specific digital research databases for Michigan’s deep geological formations relevant to CO2 storage, containment and potential for enhanced oil recovery • Producing maps and tables of physical properties as components of these databases • Compiling all information into a digital atlas • Conducting geologic and fluid flow modeling to address specific predictive uses of CO2 storage and enhanced oil recovery, including compiling data for geological and fluid flow models, formulating models, integrating data, and running the models; applying models to specific predictive uses of CO2 storage and enhanced oil recovery • Conducting technical research on CO2 sequestration and enhanced oil recovery through basic and applied research of characterizing Michigan oil and gas and saline reservoirs for CO2 storage potential volume, injectivity and containment. Based on our research, we have concluded that the Michigan Basin has excellent saline aquifer (residual entrapment) and CO2/Enhanced oil recovery related (CO2/EOR; buoyant entrapment) geological carbon sequestration potential with substantial, associated incremental oil production potential. These storage reservoirs possess at least satisfactory injectivity and reliable, permanent containment resulting from associated, thick, low permeability confining layers. Saline aquifer storage resource estimates in the two major residual entrapment, reservoir target zones (Lower Paleozoic Sandstone and Middle Paleozoic carbonate and sandstone reservoirs) are in excess of 70-80 Gmt (at an overall 10% storage efficiency factor; an approximately

    The State University of New York (SUNY), Downstate Medical Center initiated a Master of Public Health (MPH) degree program in July 2001 following planning efforts that began in 1995. Twelve students entered the program in June 2002, and currently some 110 MPH students and 12 Doctor of Public Health (DrPH) students are enrolled. This article describes the long and complex process of transforming the original MPH degree program, with its single focus on urban and immigrant health, with a student enrollment of 12 and 8 full-time faculty, into a school of public health with a large student enrollment of 122 students, 25 full-time faculty, five MPH degree tracks, and four DrPH degree tracks. The process of establishing the SUNY Downstate School of Public Health in 2009 from its inception as an MPH program in 2001 spanned a period of 8 years. This process was guided by a commitment to two basic principles. The first was to maintain the original 2005 program accreditation by the Council on Education for Public Health (CEPH). The second was to sequentially secure accreditation for all subsequent four MPH and four DrPH degree tracks through CEPH's procedure of substantive change approval. This policy assured continuous national CEPH accreditation of the original Urban and Immigrant Health MPH degree track and all added degree programs. The 5-year period following the initial CEPH accreditation of the MPH program in 2005 was one of intense development during which all of the essential elements for CEPH accreditation of a school of public health were put into place. This rapid development was made possible by the vision and full support of Downstate's president, John C. LaRosa, MD, FACP, and the dedicated efforts of many. This included the students, faculty, staff, and administrators of the School of Public Health, the school's Community Advisory Group, several external advisors, and many in the medical center's Central Administration, College of Medicine, School of Graduate

    Since November 2015, Puerto Rico has reported active mosquito-borne transmission of Zika virus. Because of the potential for Zika virus to be transmitted through transfusion of blood components, and because a high percentage of persons infected with Zika virus are asymptomatic, the Food and Drug Administration (FDA) recommended that blood collections cease in areas of the United States affected by active vector-borne transmission of Zika virus until laboratory screening of blood donations or pathogen reduction technology (PRT) for treatment of blood components can be implemented. To inform efforts to maintain the safety and availability of the blood supply in Puerto Rico, CDC, in collaboration with the Puerto Rico Department of Health, conducted a rapid assessment of blood collection and use on the island. A total of 139,369 allogeneic red blood cell (RBC) units, 45,243 platelet units, and 56,466 plasma units were collected in or imported to Puerto Rico during 2015, and 135,966 allogeneic RBC units, 13,526 therapeutic platelet units, and 25,775 plasma units were transfused. Because of the potential for local Zika virus transmission in areas with a competent mosquito vector, other areas of the United States should develop plans to ensure local blood safety and adequacy. Blood collection organizations and public health agencies should collaborate to maintain the safety and availability of local blood supplies in accordance with FDA guidance.

    Hematopoietic stem cells (HSC) derived from peripheral blood (PB) and bone marrow (BM) are frequently used for autologous and allogenic transplantations. Establishing quality control at appropriate steps of the stem cell preparation process is crucial for a successful transplantation. Microbial contamination of haematopoietic stem cells is rare but could cause a potentially mortal complication of a stem cells transplantation. We investigated the microbiological contamination of PB (291 donations) and BM (39 donations) products. Microbial cultures of 330 donations between January 2012 and June 2013 were retrospectively analyzed after the collection and preparation steps. The microbiological analysis was performed with an automated system. Hematopoietic stem cells were processed in a closed system. Additionally, in this report the environment of the working areas of stem cell preparation was monitored. We analyzed microbial contamination of the air in a class I laminar air flow clean bench at the time of preparation and in the laboratory once per month. We reported 9 (2.73%) contaminated HSC products. The most frequent bacteria isolated from PB and BM products were Bacillus species. Coagulase-negative staphylococci and Micrococcus species were the most frequent micro-organisms detected in the air microbial control. Microbial control results are necessary for the safety of hematopoietic stem cell products transplantation. Microbial control of hematopoietic stem cell products enables an early contamination detection and allows for knowledgeable decision making concerning either discarding the contaminated product or introducing an efficient antibiotic therapy. Each step of cell processing may cause a bacterial contamination. A minimum of manipulation steps is crucial for increasing the microbial purity of the transplant material. Also, the air contamination control is essential to ensure the highest quality standards of HSC products preparation.

    Minimal residual disease detection, used for clinical management of children with acute lymphoblastic leukemia, can be performed by molecular analysis of antigen-receptor gene rearrangements or by flow cytometric analysis of aberrant immunophenotypes. For flow minimal residual disease to be incorporated into larger national and international trials, a quality assured, standardized method is needed which can be performed in a multi-center setting. We report a four color, flow cytometric protocol established and validated by the UK acute lymphoblastic leukemia Flow minimal residual disease group. Quality assurance testing gave high inter-laboratory agreement with no values differing from a median consensus value by more than one point on a logarithmic scale. Prospective screening of B-ALL patients (n=206) showed the method was applicable to 88.3% of patients. The minimal residual disease in bone marrow aspirates was quantified and compared to molecular data. The combined risk category concordance (minimal residual disease levels above or below 0.01%) was 86% (n=134). Thus, this standardized protocol is highly reproducible between laboratories, sensitive, applicable, and shows good concordance with molecular-based analysis.

    Related donor haploidentical hematopoietic cell transplantation (Haplo-HCT) using post-transplantation cyclophosphamide (PT-Cy) is increasingly used in patients lacking HLA-matched sibling donors (MSD). We compared outcomes after Haplo-HCT using PT-Cy with MSD-HCT in patients with lymphoma, using the Center for International Blood and Marrow Transplant Research registry. We evaluated 987 adult patients undergoing either Haplo-HCT (n = 180) or MSD-HCT (n = 807) following reduced-intensity conditioning regimens. The haploidentical group received graft-versus-host disease (GVHD) prophylaxis with PT-Cy with or without a calcineurin inhibitor and mycophenolate. The MSD group received calcineurin inhibitor-based GVHD prophylaxis. Median follow-up of survivors was 3 years. The 28-day neutrophil recovery was similar in the two groups (95% v 97%; P = .31). The 28-day platelet recovery was delayed in the haploidentical group compared with the MSD group (63% v 91%; P = .001). Cumulative incidence of grade II to IV acute GVHD at day 100 was similar between the two groups (27% v 25%; P = .84). Cumulative incidence of chronic GVHD at 1 year was significantly lower after Haplo-HCT (12% v 45%; P < .001), and this benefit was confirmed on multivariate analysis (relative risk, 0.21; 95% CI, 0.14 to 0.31; P < .001). For Haplo-HCT v MSD-HCT, 3-year rates of nonrelapse mortality (15% v 13%; P = .41), relapse/progression (37% v 40%; P = .51), progression-free survival (48% v 48%; P = .96), and overall survival (61% v 62%; P = .82) were similar. Multivariate analysis showed no significant difference between Haplo-HCT and MSD-HCT in terms of nonrelapse mortality (P = .06), progression/relapse (P = .10), progression-free survival (P = .83), and overall survival (P = .34). Haplo-HCT with PT-Cy provides survival outcomes comparable to MSD-HCT, with a significantly lower risk of chronic GVHD. © 2016 by American Society of Clinical Oncology.

    Aim To determine if red cell distribution width (RDW) is associated with all-cause mortality in patients on chronic dialysis and to evaluate its prognostic value among validated prognostic biomarkers. Methods This is a single center, prospective longitudinal study. At the time of inclusion in January 2011, all patients were physically examined and a routine blood analysis was performed. A sera sample was preserved for determination of NT-pro-brain natriuretic peptide (NT-pro-BNP) and eosinophil cationic protein. Carotid intima media thickness (IMT) was also measured. Following one year, all-cause mortality was evaluated. Results Of 100 patients, 25 patients died during the follow-up period of one-year. Patients who died had significantly higher median [range] RDW levels (16.7% [14.3-19.5] vs 15.5% [13.2-19.7], P < 0.001. They had significantly higher Eastern Cooperative Oncology Group (ECOG) performance status (4 [2-4] vs 2 [1-4], P < 0.001), increased intima-media thickness (IMT) (0.71 [0.47-1.25] vs 0.63 [0.31-1.55], P = 0.011), increased NT-pro-BNP levels (8300 [1108-35000] vs 4837 [413-35000], P = 0.043), and increased C-reactive protein (CRP) levels (11.6 [1.3-154.2] vs 4.9 [0.4-92.9], P < 0.001). For each 1% point increase in RDW level as a continuous variable, one-year all cause mortality risk was increased by 54% in univariate Cox proportional hazard analysis. In the final model, when RDW was entered as a categorical variable, mortality risk was significantly increased (hazard ratio, 5.15, 95% confidence interval, 2.33 to 11.36) and patients with RDW levels above 15.75% had significantly shorter survival time (Log rank P < 0.001) than others. Conclusions RDW could be an additive predictor for all-cause mortality in patients on chronic dialysis. Furthermore, RDW combined with sound clinical judgment improves identification of patients who are at increased risk compared to RDW alone. PMID:23444243

Totally 240 participants were randomized to the treatment group treated with TRABC in addition to conventional Western treatment or the control group with conventional Western treatment equally for 3 months. Primary outcome was degree of disability as measured by modified Rankin Scale (mRS). Secondary outcomes were the absorption of hematoma and edema, National Institutes of Health Stroke Scale (NIHSS) scores and patient-reported outcome measures for stroke and Barthel activities of daily living index. Adverse events and mortality were also recorded. After 3 months of treatment, the rate of mRS 0-1 and mRS 0-2 in the treatment group was 72.5% and 80.4%, respectively, and in the control group 48.1% and 63.9%, respectively, with a significant difference between groups (P<0.01). Hematoma volume decreased significantly at day 7 of treatment in the treatment group than the control group (P=0.038). Average Barthel scores in the treatment group after treatment was 89.11±19.93, and in the control group 82.18±24.02 (P=0.003). NIHSS scores of the two groups after treatment decreased significantly compared with before treatment (P=0.001). Patient-reported outcomes in the treatment group were lower than the control group at day 21 and 3 months of treatment (P<0.05). There were 4 deaths, 2 in each group, and 11 adverse events, 6 in the treatment group and 5 in the control group. The integrative therapy combined TRABC with conventional Western treatment for HICH could promote hematoma absorption thus minimize neurologic impairment, without increasing intracerebral hematoma expansion and re-bleeding.

    Office blood pressure measurement using mercury sphygmomanometer is the gold standard for making diagnoses of hypertension, evaluation of cardiovascular risk and estimation of obtained control of treated hypertensives. The vast majority of epidemiologic data are based on this method. However, the importance of blood pressure variability, white coat effect as well as availability of simple devices, home and ambulatory blood pressure measurements became routine parts in routine clinical work. As mercury will be soon forbidden in clinical work such devices and methodology will be even more important. In everyday clinical practice all three techniques should be implemented and in this paper advantages and drawbacks of all techniques are discussed. In the end, based on recent data and recommendations of international societies, diagnostic algorithm was proposed. Additionally, we described the technique of non-invasive central blood pressure measurement, determination of pulse wave velocity and calculation of augmentation index, new proposed risk factors.

    The analysis of cord blood respiratory gases and acid-base values is an important adjunct for determining the extent and cause of fetal acidosis at delivery. Although the quality and reliability of the blood gas instruments have improved dramatically, constant vigilance still is required and mandated to ensure accurate and precise results. Failure to control the many sampling and analysis variables that affect cord blood gas results will limit their usefulness. Most preanalytic problems become a minor concern when the blood gas analyses are done within a few minutes after obtaining the sample. Comparison of data among centers requires, not only that reference ranges be stated, but also that various corrections or factors that were used to adjust the results be described. Perhaps, a consensus could be reached to establish the optimal method of collection and the best methods for analyzing and reporting the results from cord blood gas and acid-base studies.

    Background Circulating tumor cells (CTC) are discussed to be an ideal surrogate marker for individualized treatment in metastatic breast cancer (MBC) since metastatic tissue is often difficult to obtain for repeated analysis. We established a nine gene qPCR panel to characterize the heterogeneous CTC population in MBC patients including epithelial CTC, their receptors (EPCAM, ERBB2, ERBB3, EGFR) CTC in Epithelial-Mesenchymal-Transition [(EMT); PIK3CA, AKT2), stem cell-like CTC (ALDH1) as well as resistant CTC (ERCC1, AURKA] to identify individual therapeutic targets. Results At TP0, at least one marker was detected in 84%, at TP1 in 74% and at TP2 in 79% of the patients, respectively. The expression of ERBB2, ERBB3 and ERCC1 alone or in combination with AURKA was significantly associated with therapy failure. ERBB2 + CTC were only detected in patients not receiving ERBB2 targeted therapies which correlated with no response. Furthermore, patients responding at TP2 had a significantly prolonged overall-survival than patients never responding (p = 0.0090). Patients and Methods 2 × 5 ml blood of 62 MBC patients was collected at the time of disease progression (TP0) and at two clinical staging time points (TP1 and TP2) after 8–12 weeks of chemo-, hormone or antibody therapy for the detection of CTC (AdnaTest EMT-2/StemCell Select™, QIAGEN Hannover GmbH, Germany). After pre-amplification, multiplex qPCR was performed. Establishment was performed using various cancer cell lines. PTPRC (Protein tyrosine phosphatase receptor type C) and GAPDH served as controls. Conclusions Monitoring MBC patients using a multimarker qPCR panel for the characterization of CTC might help to treat patients accordingly in the future. PMID:27223437

    Peripheral blood stem cell (PBSC) grafts are increasingly used for autologous and allogeneic haematopoietic stem cell transplantation (alloHSCT) with the aim to hasten neutrophil and platelet engraftment and thereby to reduce transplant-related complications due to infections, bleeding and graft failure. Based on the paucity of data on PBSC transplantation in children we performed a retrospective single-center analysis comparing the outcome of children receiving mobilized PBSC from human leukocyte antigen (HLA)-identical sibling donors to bone marrow (BM) transplant recipients. Between 1996 and 2004, 16 children with haematologic malignancies and standard indication for alloHSCT underwent PBSC transplantation from HLA-identical sibling donors. The outcome of these children was compared to a historic control group of 19 bone marrow (BM) transplant recipients. Time to neutrophil engraftment, incidence of acute and chronic graft-versus-host disease (GvHD), relapse rate, transplant-related mortality, event-free and overall survival were analyzed. Neutrophil engraftment was achieved significantly faster after PBSC compared to BM transplantation with a median time to neutrophil engraftment of 11 (range: 8-21) and 19 (16-44) days for the PBSC and BM cohort, respectively (p < 0.001). Two of 19 (11 %) BM recipients did not achieve primary neutrophil engraftment and both patients died due to infectious complications. The rate of clinically significant acute GvHD > or = grade II was higher in the PBSC compared to the BM group (75 vs. 39 %; p = 0.045). Incidences of chronic GvHD (PBSC vs. BM: 60 vs. 44 %), death of disease (13 vs. 21 %) and death of complication (13 vs. 16 %) were comparable between both groups (p = ns). With a median follow up of 4.7 years (PBSC) and 10.2 years (BM) overall survival (PBSC vs. BM: 68.6 +/- 13.5 vs. 63.2 +/- 11.1 %; p = 0.65) and event-free survival (67.0 +/- 12.1 vs. 63.2 +/- 11.1 %; p = 0.80) is without demonstrable difference in both groups

    This study analyzes the efficacy in myocardial protection of two types of cardioplegia solutions, namely, blood and crystalloid cardioplegia, both given intermittently in patients undergoing coronary artery bypass grafting (CABG). Adult patients undergoing primary isolated coronary artery bypass grafting between January 1998 and January 2011 with cardiopulmonary bypass, using either blood or crystalloid cardioplegia, were identified in our database. Propensity score matching was performed to create comparable patient groups. Multivariate logistic regression analysis was performed to identify independent risk factors for perioperative myocardial damage. The primary endpoint of the study was the maximum creatine kinase-MB (CK-MB) value within 5 days postoperatively with a cut-off point of 100 U/L. Early mortality and perioperative low cardiac output syndrome in both groups were compared. The study included 7138 CABG patients: 3369 patients using crystalloid cardioplegia and 3769 using blood cardioplegia. After propensity score matching, 2585 patients per study group remained for the analysis. Wilcoxon signed-rank test revealed significantly higher CK-MB levels in patients operated with the use of blood cardioplegia. Multivariate regression analysis identified blood cardioplegia as an independent risk factor for elevated CK-MB levels. However, it was associated with lower aspartate aminotransferase (AST) levels. The type of cardioplegia had no influence on early mortality, postoperative low cardiac output syndrome or intensive care unit stay. Blood cardioplegia was identified as an independent risk factor for elevated levels of CK-MB after CABG, but was associated with lower AST levels. The authors conclude that the type of cardioplegia had no significant influence on clinical outcome. © The Author(s) 2014.

    Despite mounting clinical evidence that supports its safety, the question of the potential adverse effects of sevoflurane on renal function continues to generate some controversy. This study retrospectively evaluated pooled renal laboratory data from 22 different clinical trials that compared sevoflurane with three widely used anesthetics. The trials examined postoperative changes in serum creatinine and blood urea nitrogen levels from a total of 3, 436 ASA physical status I-IV adult surgical patients administered either sevoflurane (n = 1941) or a control drug (isoflurane, enflurane, or propofol; n = 1495) as the maintenance anesthetic. The incidences of increased serum creatinine and blood urea nitrogen concentrations were similar among patients administered sevoflurane and those administered control drugs. Additionally, no trends specific to sevoflurane were observed with respect to postoperative serum creatinine concentration and fresh gas flow rate, concurrent treatment with nephrotoxic antibiotics, or type of carbon dioxide absorbent. Our data for changes in serum creatinine and blood urea nitrogen indicate that, for exposures of less than 4 minimum alveolar anesthetic concentration/h, sevoflurane is not associated with an increased risk of renal toxicity compared with other commonly used anesthetics. For clinical purposes, the pre- to postoperative changes in serum creatinine and blood urea nitrogen are appropriate measures of renal function in surgical patients.

    The Etablissement Français du Sang Alsace (EFS Alsace) successively implemented universal use of platelet additive solutions (PASs) and pathogen inactivation (PI) for platelet components (PCs). To assess the impact of these changes, EFS Alsace evaluated PC use, red blood cell (RBC) component use, and transfusion-related adverse events after implementation of these new technologies. EFS Alsace prospectively collects data on production, distribution, and response to transfusion of all blood components with greater than 99.5% data acquisition. Adverse events attributed to platelet (PLT) transfusions were collected through a mandatory, active hemovigilance program. A retrospective review of prospectively collected data was conducted covering three periods: 1) apheresis and whole blood-derived PCs in plasma, 2) apheresis and whole blood-derived PCs with PAS, and 3) PCs prepared with PI and PAS. Data on component utilization were analyzed for all patients receiving PCs in each period and for the subset of hematology-oncology patients to evaluate PC use in an intensely transfused population. Values for all continuous variables were summarized as mean and standard deviation, median, and range. Approximately 2000 patients received PCs in each period. PLT and RBC use per patient was not increased after PI (analysis of variance, F = 1.9 and 2.9, respectively) and the incidence of acute transfusion reactions was significantly reduced (p < 0.001). Universal use of PI was implemented without impacting component use, as indicated by total dose of PLTs per patient, and outcomes to transfusion were improved. © 2010 American Association of Blood Banks.

    Background Medication non-adherence is common and results in preventable disease complications. This study assesses the effectiveness of a multifactorial intervention to improve both medication adherence and blood pressure control and to reduce cardiovascular events. Methods and Results In this multi-center, cluster-randomized trial, physicians from hospital-based hypertension clinics and primary care centers across Spain were randomized to receive and provide the intervention to their high-risk patients. Eligible patients were ≥50 years of age, had uncontrolled hypertension, and had an estimated 10-year cardiovascular risk greater than 30%. Physicians randomized to the intervention group counted patients’ pills, designated a family member to support adherence behavior, and provided educational information to patients. The primary outcome was blood pressure control at 6 months. Secondary outcomes included both medication adherence and a composite end-point of all cause mortality and cardiovascular-related hospitalizations. Seventy-nine physicians and 877 patients participated in the trial. The mean duration of follow-up was 39 months. Intervention patients were less likely to have an uncontrolled systolic blood pressure (odds ratio 0.62; 95% confidence interval [CI] 0.50–0.78) and were more likely to be adherent (OR 1.91; 95% CI 1.19–3.05) when compared with control group patients at 6 months. After five years 16% of the patients in the intervention group and 19% in the control group met the composite end-point (hazard ratio 0.97; 95% CI 0.67–1.39). Conclusions A multifactorial intervention to improve adherence to antihypertensive medication was effective in improving both adherence and blood pressure control, but it did not appear to improve long-term cardiovascular events.

    Abstract Despite advances in early diagnosis and behavioral therapies, more effective treatments for children with autism spectrum disorder (ASD) are needed. We hypothesized that umbilical cord blood‐derived cell therapies may have potential in alleviating ASD symptoms by modulating inflammatory processes in the brain. Accordingly, we conducted a phase I, open‐label trial to assess the safety and feasibility of a single intravenous infusion of autologous umbilical cord blood, as well as sensitivity to change in several ASD assessment tools, to determine suitable endpoints for future trials. Twenty‐five children, median age 4.6 years (range 2.26–5.97), with a confirmed diagnosis of ASD and a qualified banked autologous umbilical cord blood unit, were enrolled. Children were evaluated with a battery of behavioral and functional tests immediately prior to cord blood infusion (baseline) and 6 and 12 months later. Assessment of adverse events across the 12‐month period indicated that the treatment was safe and well tolerated. Significant improvements in children's behavior were observed on parent‐report measures of social communication skills and autism symptoms, clinician ratings of overall autism symptom severity and degree of improvement, standardized measures of expressive vocabulary, and objective eye‐tracking measures of children's attention to social stimuli, indicating that these measures may be useful endpoints in future studies. Behavioral improvements were observed during the first 6 months after infusion and were greater in children with higher baseline nonverbal intelligence quotients. These data will serve as the basis for future studies to determine the efficacy of umbilical cord blood infusions in children with ASD.

    To investigate the impact of a Westernizing diet on fat intake, red blood cell fatty acid composition, and health risks among Yup'ik Eskimos living in rural Alaskan Native communities. Diet data and blood specimens were collected from 530 Yup'ik Eskimos aged 14 to 94 years old. Height, weight, and waist circumference were measured. Comparisons of select fatty acid intake between participants in quintiles of traditional food intake (percent energy) were made using analyses of variance and post hoc Bonferroni tests. General linear models were used to determine the association between traditional food intake and health outcomes. Fatty acid composition of the diet differed according to the level of traditional food intake. Traditional food intake was positively associated with higher total fat, eicosapentaenoic acid, and docosahexaenoic acid intake. No association was observed between traditional food intake and saturated fatty acid intake; indeed, participants consuming more traditional foods derived a substantially smaller proportion of their dietary fatty acids from saturated fatty acids (P<0.001). Analyses of red blood cell fatty acid composition supported these findings. After multivariable adjustment, traditional food intake was significantly positively associated with high-density lipoprotein cholesterol concentration and significantly negatively associated with triglyceride concentration (P<0.001). Diets emphasizing traditional Alaskan Native foods were associated with a fatty acid profile promoting greater cardiovascular health than diets emphasizing Western foods. Further research needs to evaluate the effects of a Westernizing diet on the overall diet of Alaskan Natives.

    The basis for this successful collaboration was face-to-face communication. Though it was sometimes stressful being on the road so much, I really learned the importance of being present to work together and ask questions in person. Another measure of success was that in the midst of this project and traveling, my wife and I managed to start a family. My oldest boy got a real kick out of visiting Space Center Houston when he was two to learn all about the "face futtle" which goes way up in the sky. When practical, collocation and face-to-face communication on a project eliminate misunderstandings, establish relationships, make information more easily accessible, and promote a team atmosphere. Compromise is key to balancing both family and career goals. Knowing when to prioritize each is important to success in both aspects.

    With the introduction of highly sensitive hepatitis B surface antigen immunoassay, transfusion associated HBV infection have reduced drastically but they still tend to occur due to blood donors with occult hepatitis B infection (OBI) and window period (WP) infection. Sera from, 24338 healthy voluntary blood donors were screened for HBsAg, HIV and HCV antibody using Vitros Enhanced Chemiluminescent Immunoassay. The median age of the donor population was 30 (range 18-54) with male preponderance (98%). All serologically negative samples were screened by nucleic acid testing (NAT) for viral DNA and RNA. NAT-positive samples were subjected to discriminatory NAT for HBV, HCV, and HIV and all samples positive for HBV DNA were tested for anti-HBc, anti-HBs, HBeAg. Viral load was determined using artus HBV RG PCR Kit. Of the 24,338 donors screened, 99.81% (24292/24338) were HBsAg negative of which NAT was positive for HBV DNA in 0.0205% (5/24292) donors. Four NAT positive donors had viral load of <200 IU/ml making them true cases of OBI. One NAT positive donor was negative for all antibodies making it a case of WP infection. Among OBI donors, 75% (3/4) were immune and all were negative for HBeAg. Precise HBV viral load could not be determined in all (5/5) NAT positive donors due to viral loads below the detection limit of the artus HBV RG PCR Kit. The overall incidence of OBI and WP infections was found to be low at 1 in 6503 and 1 in 24214 donations, respectively. More studies are needed to determine the actual burden of WP infections in Indian blood donors.

    Patients with blood disorders colonized with antibiotic-resistant bacteria (ARB) are prone to systemic infections that are difficult to treat. Reintroduction of commensal bacteria in a murine model of enterococcal colonization of the gut can lead to eradication of enterococci. We hypothesized that fecal microbiota transplantation (FMT) could be used to eradicate ARB in humans. Participants colonized with ARB were treated with intraduodenal FMT according to a prospective protocol (NCT02461199). The primary endpoint was complete ARB decolonization at 1 month after FMT. Secondary endpoints included safety assessment and partial ARB decolonization. Microbiome sequencing was performed to investigate the influence of microbial composition of the transplanted material on the outcome of FMT. Twenty-five FMTs were performed in 20 participants (including 40% who had neutropenia) who were colonized by a median of 2 (range, 1-4) strains of ARB. The primary endpoint was reached in 15/25 (60%) of the FMTs and more frequently in cases in which there was no periprocedural use of antibiotics (79% vs 36%, P < .05). Among participants, 15/20 (75%) experienced complete ARB decolonization. There were no severe adverse events, and partial ARB decolonization was observed in 20/25 (80%) of the FMTs. The microbiota composition analysis revealed higher abundance of Barnesiella spp., Bacteroides, and Butyricimonas and greater bacterial richness in the fecal material, resulting in eradication of Klebsiella pneumoniae compared with nonresponders. FMT in patients with blood disorders is safe and promotes eradication of ARB from the gastrointestinal tract. NCT02461199.

    To explore the feasibility of a research-based program for patient-centered consultations to improve medical adherence and blood glucose control in patients with type 2 diabetes. The patient-centered empowerment, motivation, and medical adherence (EMMA) consultation program consisted of three individual consultations and one phone call with a single health care professional (HCP). Nineteen patients with type 2 diabetes completed the feasibility study. Feasibility was assessed by a questionnaire-based interview with patients 2 months after the final consultation and interviews with HCPs. Patient participation was measured by 10-second event coding based on digital recordings and observations of the consultations. HCPs reported that EMMA supported patient-centered consultations by facilitating dialogue, reflection, and patient activity. Patients reported that they experienced valuable learning during the consultations, felt understood, and listened to and felt a trusting relationship with HCPs. Consultations became more person-specific, which helped patients and HCPs to discover inadequate diabetes self-management through shared decision-making. Compared with routine consultations, HCPs talked less and patients talked more. Seven of ten dialogue tools were used by all patients. It was difficult to complete the EMMA consultations within the scheduled time. The EMMA program was feasible, usable, and acceptable to patients and HCPs. The use of tools elicited patients' perspectives and facilitated patient participation and shared decision-making.

    Purpose To explore the feasibility of a research-based program for patient-centered consultations to improve medical adherence and blood glucose control in patients with type 2 diabetes. Patients and methods The patient-centered empowerment, motivation, and medical adherence (EMMA) consultation program consisted of three individual consultations and one phone call with a single health care professional (HCP). Nineteen patients with type 2 diabetes completed the feasibility study. Feasibility was assessed by a questionnaire-based interview with patients 2 months after the final consultation and interviews with HCPs. Patient participation was measured by 10-second event coding based on digital recordings and observations of the consultations. Results HCPs reported that EMMA supported patient-centered consultations by facilitating dialogue, reflection, and patient activity. Patients reported that they experienced valuable learning during the consultations, felt understood, and listened to and felt a trusting relationship with HCPs. Consultations became more person-specific, which helped patients and HCPs to discover inadequate diabetes self-management through shared decision-making. Compared with routine consultations, HCPs talked less and patients talked more. Seven of ten dialogue tools were used by all patients. It was difficult to complete the EMMA consultations within the scheduled time. Conclusion The EMMA program was feasible, usable, and acceptable to patients and HCPs. The use of tools elicited patients’ perspectives and facilitated patient participation and shared decision-making. PMID:26366060

    In November 2013, the American College of Cardiology and the American Heart Association released a clinical practice guideline on the treatment of blood cholesterol to reduce atherosclerotic cardiovascular disease (ASCVD) risk in adults. The recommendation identifies 4 patient groups with strong evidence that the benefits of reduction in ASCVD events from statin therapy exceed adverse events. For these patients, initiating statin therapy of an appropriate intensity to reduce ASCVD risk and minimize adverse effects is recommended. A new risk estimator based on a pooled cohort equation is presented for estimating 10-year ASCVD risk. There is also a recommendation to engage in a clinician-patient discussion before initiating a statin, especially for primary prevention of ASCVD. This paper summarizes a discussion between a cardiologist and an internist about how each clinician would balance these factors and what treatment they would suggest for an individual patient.

    Background Biosimilar granulocyte colony-stimulating factor (G-CSF) has recently been introduced into clinical practice. G-CSFs are used to mobilize CD34+ cells and accelerate engraftment after transplantation. However, in Asia, particularly in Japan, data for peripheral blood stem cell (PBSC) mobilization by this biosimilar G-CSF are currently lacking. Therefore, the clinical efficacy and safety of biosimilar G-CSF for hematopoietic stem cell transplantation needs to be evaluated in a Japanese context. Materials and methods The subjects included two groups of patients with malignant lymphoma and multiple myeloma. All patients received chemotherapy priming for the mobilization of PBSCs. All patients were treated with chemotherapy followed by the administration of either the biosimilar G-CSF, filgrastim XM02 (FBNK), or the originators, filgrastim, or lenograstim. Results There were no significant differences among FBNK, filgrastim, and lenograstim treatments in the numbers of CD34+ cells in harvested PBSCs, the scores for granulocyte/macrophage colony forming units, or for malignant lymphoma and multiple myeloma patients evaluated as separate or combined cohorts. In addition, there were no significant differences in safety, side effects, complications, or the time to engraftment after autologous hematopoietic stem cell transplantation. Conclusion Biosimilar FBNK shows the same efficacy and safety as originator G-CSFs for facilitating bone marrow recovery in Japanese malignant lymphoma and multiple myeloma patients undergoing stem cell transplantation. In addition, it is less expensive than the originators, reducing hospitalization costs. PMID:28182150

    We present results of peripheral blood stem cell (PBSC) mobilization, collection, and follow-up from 3928 consecutive unrelated stem cell donors. Assessments were performed prospectively at baseline, leukapheresis, 1 month, 6 months, and annually after PBSC donation. During follow-up, side effects were recorded by return post questionnaires. The median CD34+ cell counts on day 5 were 67.5/microL in male and 51/microL in female donors. Bone pain and headache were the most common side effects of recombinant human granulocyte-colony stimulating factor. Central venous access was required for 23 donations (0.6%). Throughout the follow-up, the absolute neutrophil counts were slightly below the initial baseline values but remained within the normal range. The majority of the donors reported good or very good health. Malignancies occurred in 12 donors (0.3%), among whom were 1 case of acute myeloid leukemia, 1 case of chronic lymphatic leukemia, and 2 cases of Hodgkin disease. Only the incidence of Hodgkin lymphoma differed significantly from an age-adjusted population. In conclusion, 7.5 microg/kg per day lenograstim proved to be safe and effective for mobilizing hematopoietic stem cells for allogeneic transplantation. Long-term monitoring of healthy PBSC donors remains important to guarantee the safety standards of PBSC mobilization and collection.

    Outcomes of 159 young patients with inherited metabolic disorders (IMDs) undergoing transplantation with partially HLA-mismatched unrelated donor umbilical cord blood were studied to investigate the impact of graft and patient characteristics on engraftment, overall survival (OS), and graft-versus-host disease (GVHD). Patients received myeloablative chemotherapy (busulfan, cyclophosphamide, ATG) and cyclosporine-based GVHD prophylaxis. Infused cell doses were high (7.57 × 107/kg) because of the patients' young age (median, 1.5 years) and small size (median, 12 kg). Median follow-up was 4.2 years (range, 1-11 years). The cumulative incidences of neutrophil and platelet engraftment were 87.1% (95% confidence interval [CI], 81.8%-92.4%) and 71.0% (95% CI, 63.7%-78.3%). A total of 97% achieved high (> 90%) donor chimerism. Serum enzyme normalized in 97% of patients with diseases for which testings exist. Grade III/IV acute GVHD occurred in 10.3% (95% CI, 5.4%-15.2%) of patients. Extensive chronic GVHD occurred in 10.8% (95% CI, 5.7%-15.9%) of patients by 1 year. OS at 1 and 5 years was 71.8% (95% CI, 64.7%-78.9%) and 58.2% (95% CI, 49.7%-66.6%) in all patients and 84.5% (95% CI, 77.0%-92.0%) and 75.7% (95% CI, 66.1%-85.3%) in patients with high (80-100) performance score. In multivariate analysis, favorable factors for OS were high pretransplantation performance status, matched donor/recipient ethnicity, and higher infused colony forming units. PMID:18587012

    We evaluated outcomes and associated prognostic factors in 233 patients undergoing allogeneic hematopoietic cell transplantation (HCT) for primary myelofibrosis (MF) using reduced-intensity conditioning (RIC). The median age at RIC HCT was 55 yr. Donors were a matched sibling donor (MSD) in 34% of RIC HCTs, an HLA well-matched unrelated donor (URD) in 45%, and a partially matched/mismatched URD in 21%. Risk stratification according to the Dynamic International Prognostic Scoring System (DIPSS) was 12% low, 49% intermediate-1, 37% intermediate-2, and 1% high. The probability of survival at 5 yr was 47% (95% confidence interval [CI], 40% to 53%). In a multivariate analysis, donor type was the sole independent factor associated with survival. Adjusted probabilities of survival at 5-yr were 56% (95% CI, 44% to 67%) for MSD, 48% (95% CI, 37% to 58%) for well-matched URD, and 34% (95% CI, 21% to 47%) for partially matched/mismatched URD (P = .002). The relative risk (RR) for NRM was 3.92 (P = .006) for well-matched URD and 9.37 (P < .0001) for partially matched/mismatched URD. Trends toward increased NRM (RR, 1.7; P = .07) and inferior survival (RR, 1.37; P = .10) were observed in DIPSS intermediate-2/high-risk patients compared with DIPSS low/intermediate-1 risk patients. Our data indicate that RIC HCT is a potentially curative option for patients with MF, and that donor type is the most important factor influencing survival in these patients.

    A previous economic analysis of self-management, that is, self-monitoring with self-titration of antihypertensive medication evaluated cost-effectiveness among patients with uncomplicated hypertension. This study considered cost-effectiveness of self-management in those with raised blood pressure plus diabetes, chronic kidney disease and/or previous cardiovascular disease. A Markov model-based economic evaluation was undertaken to estimate the long-term cost-effectiveness of self-management of blood pressure in a cohort of 70-year-old 'high risk' patients, compared with usual care. The model used the results of the TASMIN-SR trial. A cost-utility analysis was undertaken from a UK health and social care perspective, taking into account lifetime costs of treatment, cardiovascular events and quality adjusted life years. A subgroup analysis ran the model separately for men and women. Deterministic sensitivity analyses examined the effect of different time horizons and reduced effectiveness of self-management. Base-case results indicated that self-management was cost-effective compared with usual care, resulting in more quality adjusted life years (0.21) and cost savings (-£830) per patient. There was a 99% chance of the intervention being cost-effective at a willingness to pay threshold of £20,000 per quality adjusted life year gained. Similar results were found for separate cohorts of men and women. The results were robust to sensitivity analyses, provided that the blood pressure lowering effect of self-management was maintained for more than a year. Self-management of blood pressure in high-risk people with poorly controlled hypertension not only reduces blood pressure, compared with usual care, but also represents a cost-effective use of healthcare resources. © The European Society of Cardiology 2015.

    Racial and ethnic disparities have been reported in clinical trial/research participation, utilization of autologous and allogeneic blood and marrow transplantation (BMT), and availability of allogeneic donors. We performed a population-based cohort study to investigate adult hematologic malignancy referrals to a US tertiary cancer center, utilization of BMT, and participation in clinical trial, survey, and biospecimen research by race. US Census Data and the New York State Public Access Cancer Epidemiology Database identified the racial distribution of the general population and new hematologic malignancy cases in the primary catchment area. From 2005 to 2011, 1106 patients aged 18 to 75 years were referred for BMT consultation; although the rate of BMT among hematologic malignancy referrals did not differ by race, the reasons for not receiving a BMT did. Participation in biospecimen research did not vary by race; however, African Americans and other minorities were significantly less likely to participate in survey research than European Americans. Although rates of hematologic malignancy referrals and use of BMT for minorities appear to be low (<10%), they closely reflect the race distribution of all hematologic malignancy cases and the western New York population. African Americans are equally likely as other races to participate in biospecimen banking, but further study is needed to understand reasons for lower participation in survey research.

    A longitudinal, prospective, observational, single-center, cohort study on healthy donors (HDs) was designed to identify predictors of CD34+ cells on day 5 with emphasis on the predictive value of the basal CD34+ cell count. As potential predictors of mobilization, age, sex, body weight, height, blood volume as well as white blood cell count, peripheral blood (PB) mononuclear cells, platelet count, hematocrit, and hemoglobin levels were considered. Two different evaluations of CD34+ cell counts were determined for each donor: baseline (before granulocyte colony-stimulating factor [G-CSF] administration) and in PB after G-CSF administration on the morning of the fifth day (day 5). A total 128 consecutive HDs (66 males) with a median age of 43 years were enrolled. CD34+ levels on day 5 displayed a non-normal distribution with a median value of 75.5 cells/µL. To account for the non-normal distribution of the dependent variable, a quantile regression analysis to predict CD34+ on day 5 using the baseline value of CD34+ as the key predictor was performed. On crude analysis, a baseline value of CD34+ ranging from 0.5 to 1 cells/µL predicts a median value of 50 cells/µL on day 5; a value of 2 cells/µL predicts a median value of 70.7 cells/µL; a value of 3-4 cells/µL predicts a median value of 91.3 cells/µL, and a value ≥ 5 predicts a median value of 112 cells/µL. In conclusion, the baseline PB CD34+ cell count correlates with the effectiveness of allogeneic PBSC mobilization and could be useful to plan the collection.

  4. Money for Blood and Markets for Blood.

    PubMed

    Derpmann, Simon; Quante, Michael

    2015-12-01

    Ontario's Bill 178 proposing a Voluntary Blood Donations Act declares the offer or acceptance of payment for the donation of blood a legal offence and makes it subject to penalty. The bill reinvigorates a fundamental debate about the ethical problems associated with the payment of money for blood. Scarcity of blood donors is a recurring problem in most health systems, and monetary remuneration of the willingness to donate blood is regularly discussed--and sometimes practiced--as a means to overcome scarcity in blood. However, making blood an object of economic exchange has long aroused ethical concerns that often refer to the specific meaning of blood. From the perspective of a modern understanding of money as a metric of economic value, the exchange of money for blood--shed or given--is seen as ethically troubling, because it appears to imply a commensurability of the value of human life and economic wealth. In this paper, we begin with a general taxonomy of the types of arguments that speak in favour or against compensating donors for giving blood. We then describe the context in which the discussion about payment for blood arises, and of the specific aims and concerns that are brought forward in this context. This is used to reconstruct the normative background that supports the rejection of payment for blood as it is envisaged in Bill 178 and the aims of the proposal. We then argue that while a payment indeed changes the nature of a blood donation in an ethically considerable way, we do not believe that decisive arguments against the monetary remuneration of blood donations can be substantiated, at least not independently of assuming specific societal circumstances. Thus it may be possible to establish a stable and safe blood supply through just gratification while at the same time taking strong provisions against social disconnection, injustice, exploitation or heteronomy.

    Afghanistan is a country with population of over 28 million. The long term conflicts have devastated country's qualified resources including human resources. ANBSTS was established by MoPH as the country national blood service. Currently in addition to central and regional blood centers of ANBSTS many other hospitals have their own transfusion services. Blood donation in Afghanistan mainly depends on replacement donors. Donor selection and donor interview are not very efficient. Most of the blood in Afghanistan is administered as fresh whole blood. Although blood transfusion services in Afghanistan require more efforts to be fully efficient, based on recent improvements in working procedures of ANBSTS a promising future for blood transfusion services in Afghanistan is predicted.

  14. Blood transfusion in obstetrics.

    PubMed

    Nigam, A; Prakash, A; Saxena, P

    2013-01-01

    Transfusion of blood and blood components is a common practice in obstetric wards but it is not without risk. The incidence of transfusion reactions varies from 4 in every hundred transfusions for non-haemolytic reactions to one in every 40,000 for haemolytic transfusion reactions. The physiological basis of blood transfusion is outlined in this article. Most of the donated blood is processed into components: packed red cells (PRBCs), platelets, and fresh frozen plasma (FFP) or cryoprecipitate. Various alternatives to blood transfusion exist and include autotransfusion, pre-autologous blood storage, use of oxygen carrying blood substitutes and intraoperative cell salvage. Despite the risks associated with transfusions, obstetricians are frequently too aggressive in transfusing blood and blood products to their patients. Acute blood loss in obstetrics is usually due to placenta praevia, postpartum blood loss and surgery related. An early involvement of a consultant obstetrician, anaesthetist, haematologist and the blood bank is essential. There are no established criteria for initiating red cell transfusions and the decision is purely based on clinical and haematological parameters, which have been discussed along with the general principles of blood transfusion in obstetrics and some practical guidelines.
