    Beratan, D.

    1993-01-01

    A molecular shift register memory at the molecular level is described. The memory elements consist of molecules can exit in either an oxidized or reduced state and the bits are shifted between the cells with photoinduced electron transfer reactions.

  3. Molecular implementation of molecular shift register memories

    NASA Technical Reports Server (NTRS)

    Beratan, David N. (Inventor); Onuchic, Jose N. (Inventor)

    1991-01-01

    An electronic shift register memory (20) at the molecular level is described. The memory elements are based on a chain of electron transfer molecules (22) and the information is shifted by photoinduced (26) electron transfer reactions. Thus, multi-step sequences of charge transfer reactions are used to move charge with high efficiency down a molecular chain. The device integrates compositions of the invention onto a VLSI substrate (36), providing an example of a molecular electronic device which may be fabricated. Three energy level schemes, molecular implementation of these schemes, optical excitation strategies, charge amplification strategies, and error correction strategies are described.

  4. A molecular shift register based on electron transfer

    NASA Technical Reports Server (NTRS)

    Hopfield, J. J.; Onuchic, Josenelson; Beratan, David N.

    1988-01-01

    An electronic shift-register memory at the molecular level is described. The memory elements are based on a chain of electron-transfer molecules and the information is shifted by photoinduced electron-transfer reactions. This device integrates designed electronic molecules onto a very large scale integrated (silicon microelectronic) substrate, providing an example of a 'molecular electronic device' that could actually be made. The design requirements for such a device and possible synthetic strategies are discussed. Devices along these lines should have lower energy usage and enhanced storage density.

  5. Electronic shift register memory based on molecular electron-transfer reactions

    NASA Technical Reports Server (NTRS)

    Hopfield, J. J.; Onuchic, Jose Nelson; Beratan, David N.

    1989-01-01

    The design of a shift register memory at the molecular level is described in detail. The memory elements are based on a chain of electron-transfer molecules incorporated on a very large scale integrated (VLSI) substrate, and the information is shifted by photoinduced electron-transfer reactions. The design requirements for such a system are discussed, and several realistic strategies for synthesizing these systems are presented. The immediate advantage of such a hybrid molecular/VLSI device would arise from the possible information storage density. The prospect of considerable savings of energy per bit processed also exists. This molecular shift register memory element design solves the conceptual problems associated with integrating molecular size components with larger (micron) size features on a chip.

  6. Comparison of nurse staffing based on changes in unit-level workload associated with patient churn.

    PubMed

    Hughes, Ronda G; Bobay, Kathleen L; Jolly, Nicholas A; Suby, Chrysmarie

    2015-04-01

    This analysis compares the staffing implications of three measures of nurse staffing requirements: midnight census, turnover adjustment based on length of stay, and volume of admissions, discharges and transfers. Midnight census is commonly used to determine registered nurse staffing. Unit-level workload increases with patient churn, the movement of patients in and out of the nursing unit. Failure to account for patient churn in staffing allocation impacts nurse workload and may result in adverse patient outcomes. Secondary data analysis of unit-level data from 32 hospitals, where nursing units are grouped into three unit-type categories: intensive care, intermediate care, and medical surgical. Midnight census alone did not account adequately for registered nurse workload intensity associated with patient churn. On average, units were staffed with a mixture of registered nurses and other nursing staff not always to budgeted levels. Adjusting for patient churn increases nurse staffing across all units and shifts. Use of the discharges and transfers adjustment to midnight census may be useful in adjusting RN staffing on a shift basis to account for patient churn. Nurse managers should understand the implications to nurse workload of various methods of calculating registered nurse staff requirements. © 2013 John Wiley & Sons Ltd.

  18. The association of insurance status on the probability of transfer for pediatric trauma patients.

    PubMed

    Hamilton, Emma C; Miller, Charles C; Cotton, Bryan A; Cox, Charles; Kao, Lillian S; Austin, Mary T

    2016-12-01

    The purpose of this study was to evaluate the association of insurance status on the probability of transfer of pediatric trauma patients to level I/II centers after initial evaluation at lower level centers. A retrospective review of all pediatric trauma patients (age<16years) registered in the 2007-2012 National Trauma Data Bank was performed. Multiple regression techniques controlling for clustering at the hospital level were used to determine the impact of insurance status on the probability of transfer to level I/II trauma centers. Of 38,205 patients, 33% of patients (12,432) were transferred from lower level centers to level I/II trauma centers. Adjusting for demographics and injury characteristics, children with no insurance had a higher likelihood of transfer than children with private insurance. Children with public or unknown insurance status were no more likely to be transferred than privately insured children. There were no variable interactions with insurance status. Among pediatric trauma patients, lack of insurance is an independent predictor for transfer to a major trauma center. While burns, severely injured, and younger patients remain the most likely to be transferred, these findings suggest a triage bias influenced by insurance status. Additional policies may be needed to avoid unnecessary transfer of uninsured pediatric trauma patients. Case-control study, level III. Copyright © 2016 Elsevier Inc. All rights reserved.

  1. Regulation of veterinary antibiotics in Australia.

    PubMed

    Dyke, T M

    2003-01-01

    The Australian Pesticides and Veterinary Medicines Authority (APVMA)* registers veterinary antibiotic products before they can be supplied, distributed or sold in Australia. Extensive scientific assessment on all new veterinary antibiotic products is undertaken for the APVMA by experts in other government agencies including the Therapeutic Goods Administration (toxicology), the National Occupational Health and Safety Commission (occupational health and safety), Environment Australia (environmental hazards) and state departments of agriculture or primary industry (efficacy and safety) as well as APVMA assessments on food residues, trade and manufacturing. The National Health and Medical Research Council Expert Advisory Group on Antimicrobial Resistance provides advice to the APVMA on the potential transfer of antibiotic resistance from the use of antibiotics in animals to humans, and the impact transfer may have on public health. Food Standards Australia New Zealand (previously Australia New Zealand Food Authority) set maximum residue levels for human foods. The APVMA monitors registered product use through compliance activities and an adverse experience reporting program, and reviews registered products as necessary. The import, manufacture, supply and use of veterinary antibiotics are regulated by Commonwealth and State governments in Australia.

  3. Two-phase charge-coupled device

    NASA Technical Reports Server (NTRS)

    Kosonocky, W. F.; Carnes, J. E.

    1973-01-01

    A charge-transfer efficiency of 99.99% per stage was achieved in the fat-zero mode of operation of 64- and 128-stage two-phase charge-coupled shift registers at 1.0-MHz clock frequency. The experimental two-phase charge-coupled shift registers were constructed in the form of polysilicon gates overlapped by aluminum gates. The unidirectional signal flow was accomplished by using n-type substrates with 0.5 to 1.0 ohm-cm resistivity in conjunction with a channel oxide thickness of 1000 A for the polysilicon gates and 3000 A for the aluminum gates. The operation of the tested shift registers with fat zero is in good agreement with the free-charge transfer characteristics expected for the tested structures. The charge-transfer losses observed when operating the experimental shift registers without the fat zero are attributed to fast interface state trapping. The analytical part of the report contains a review backed up by an extensive appendix of the free-charge transfer characteristics of CCD's in terms of thermal diffusion, self-induced drift, and fringing field drift. Also, a model was developed for the charge-transfer losses resulting from charge trapping by fast interface states. The proposed model was verified by the operation of the experimental two-phase charge-coupled shift registers.

  4. Mental models and language registers in the psychoanalysis of psychosis: an overview of a thirteen-year analysis.

    PubMed

    Lombardi, Riccardo

    2003-08-01

    The author suggests that the use of mental models and language registers may help an analysis to proceed, especially in psychosis, when the patient has not yet developed a mental space that will allow him/her the functions of knowledge and containment of emotions. Models, according to Bion, are a primitive approach to abstraction and a manifestation of the analyst's reverie that enables him/her to transform sense data into alpha-elements. Ferrari, in a further development of Bion's theories, hypothesises a relationship between the transference and the internal level of body-mind communication, and proposes the use of language registers to sustain the psychoanalytic process. The author presents several clinical examples from a thirteen-year, four-session-a-week analysis of a psychotic analysand who was initially confused, paranoid and altogether unable to bring self-reflective thought to bear on her overwhelming emotions and had, by the end of the analysis, completely recovered from her psychotic symptoms. The clinical material shows how the technical tools of mental models and language registers helped in the construction of a mental space and spatio-temporal parameters, permitting the patient to tolerate overwhelming concrete emotions and finally to recognise and work through the emotions of an intense transference.

  1. The CADSS design automation system. [computerized design language for small digital systems

    NASA Technical Reports Server (NTRS)

    Franke, E. A.

    1973-01-01

    This research was designed to implement and extend a previously defined design automation system for the design of small digital structures. A description is included of the higher level language developed to describe systems as a sequence of register transfer operations. The system simulator which is used to determine if the original description is correct is also discussed. The design automation system produces tables describing the state transistions of the system and the operation of all registers. In addition all Boolean equations specifying system operation are minimized and converted to NAND gate structures. Suggestions for further extensions to the system are also given.

  2. Helium-induced one-neutron transfer to levels in 162Dy

    Andersen, E.; Helstrup, H.; Løvhøiden, G.; Thorsteinsen, T. F.; Guttormsen, M.; Messelt, S.; Tveter, T. S.; Hofstee, M. A.; Schippers, J. M.; van der Werf, S. Y.

    1992-12-01

    Levels in 162Dy have been studied in the 161Dy(α, 3He) and 163Dy( 3He, α) reactions with 50 MeV α- and 3He-beams from the KVI cyclotron in Groningen. The reaction products were analyzed in the QMG/2 magnetic spectrograph and registered in a two-dimensional detector system. The observed levels and cross sections are well described by the Nilsson model with the exception of the three levels at 1578, 1759 and 1990 keV. The present data combined with previous results strongly indicate that these levels are the spin-4, -6, and -8 members of the S-band.

  7. Modeling the impact of preflushing on CTE in proton irradiated CCD-based detectors

    NASA Astrophysics Data System (ADS)

    Philbrick, R. H.

    2002-04-01

    A software model is described that performs a "real world" simulation of the operation of several types of charge-coupled device (CCD)-based detectors in order to accurately predict the impact that high-energy proton radiation has on image distortion and modulation transfer function (MTF). The model was written primarily to predict the effectiveness of vertical preflushing on the custom full frame CCD-based detectors intended for use on the proposed Kepler Discovery mission, but it is capable of simulating many other types of CCD detectors and operating modes as well. The model keeps track of the occupancy of all phosphorous-silicon (P-V), divacancy (V-V) and oxygen-silicon (O-V) defect centers under every CCD electrode over the entire detector area. The integrated image is read out by simulating every electrode-to-electrode charge transfer in both the vertical and horizontal CCD registers. A signal level dependency on the capture and emission of signal is included and the current state of each electrode (e.g., barrier or storage) is considered when distributing integrated and emitted signal. Options for performing preflushing, preflashing, and including mini-channels are available on both the vertical and horizontal CCD registers. In addition, dark signal generation and image transfer smear can be selectively enabled or disabled. A comparison of the charge transfer efficiency (CTE) data measured on the Hubble space telescope imaging spectrometer (STIS) CCD with the CTE extracted from model simulations of the STIS CCD show good agreement.

    Riks-Stroke, the Swedish Stroke Register, is the world's longest-running national stroke quality register (established in 1994) and includes all 76 hospitals in Sweden admitting acute stroke patients. The development and maintenance of this sustainable national register is described. Riks-Stroke includes information on the quality of care during the acute phase, rehabilitation and secondary prevention of stroke, as well as data on community support. Riks-Stroke is unique among stroke quality registers in that patients are followed during the first year after stroke. The data collected describe processes, and medical and patient-reported outcome measurements. The register embraces most of the dimensions of health-care quality (evidence-based, safe, provided in time, distributed fairly and patient oriented). Annually, approximately 25,000 patients are included. In 2009, approximately 320,000 patients had been accumulated (mean age 76-years). The register is estimated to cover 82% of all stroke patients treated in Swedish hospitals. Among critical issues when building a national stroke quality register, the delicate balance between simplicity and comprehensiveness is emphasised. Future developments include direct transfer of data from digital medical records to Riks-Stroke and comprehensive strategies to use the information collected to rapidly implement new evidence-based techniques and to eliminate outdated methods in stroke care. It is possible to establish a sustainable quality register for stroke at the national level covering all hospitals admitting acute stroke patients. Riks-Stroke is fulfilling its main goals to support continuous quality improvement of Swedish stroke services and serve as an instrument for following up national stroke guidelines. © 2010 The Authors.

  11. Advanced investigation of two-phase charge-coupled devices

    NASA Technical Reports Server (NTRS)

    Kosonocky, W. F.; Carnes, J. E.

    1973-01-01

    The performance of experimental two phase, charge-coupled shift registers constructed using polysilicon gates overlapped by aluminum gates was studied. Shift registers with 64, 128, and 500 stages were built and operated. Devices were operated at the maximum clock frequency of 20 MHz. Loss per transfer of less than .0001 was demonstrated for fat zero operation. The effect upon transfer efficiency of various structural and materials parameters was investigated including substrate orientation, resistivity, and conductivity type; channel width and channel length; and method of channel confinement. Operation of the devices with and without fat zero was studied as well as operation in the complete charge transfer mode and the bias charge, or bucket brigade mode.

  15. Design Method For Ultra-High Resolution Linear CCD Imagers

    1984-11-01

    This paper presents the design method to achieve ultra-high resolution linear imagers. This method utilizes advanced design rules and novel staggered bilinear photo sensor arrays with quadrilinear shift registers. Design constraint in the detector arrays and shift registers are analyzed. Imager architecture to achieve ultra-high resolution is presented. The characteristics of MTF, aliasing, speed, transfer efficiency and fine photolithography requirements associated with this architecture are also discussed. A CCD imager with advanced 1.5 um minimum feature size was fabricated. It is intended as a test vehicle for the next generation small sampling pitch ultra-high resolution CCD imager. Standard double-poly, two-phase shift registers were fabricated at an 8 um pitch using the advanced design rules. A special process step that blocked the source-drain implant from the shift register area was invented. This guaranteed excellent performance of the shift registers regardless of the small poly overlaps. A charge transfer efficiency of better than 0.99995 and maximum transfer speed of 8 MHz were achieved. The imager showed excellent performance. The dark current was less than 0.2 mV/ms, saturation 250 mV, adjacent photoresponse non-uniformity ± 4% and responsivity 0.7 V/ μJ/cm2 for the 8 μm x 6 μm photosensor size. The MTF was 0.6 at 62.5 cycles/mm. These results confirm the feasibility of the next generation ultra-high resolution CCD imagers.

    Simulation-based learning is increasingly used by healthcare professionals as a safe method to learn and practice non-technical skills, such as communication and leadership, required for effective crisis resource management (CRM). This systematic review was conducted to gain a better understanding of the impact of simulation-based CRM teaching on transfer of learning to the workplace and subsequent changes in patient outcomes. Studies on CRM, crisis management, crew resource management, teamwork, and simulation published up to September 2012 were searched in MEDLINE(®), EMBASE™, CINAHL, Cochrane Central Register of Controlled Trials, and ERIC. All studies that used simulation-based CRM teaching with outcomes measured at Kirkpatrick Level 3 (transfer of learning to the workplace) or 4 (patient outcome) were included. Studies measuring only learners' reactions or simple learning (Kirkpatrick Level 1 or 2, respectively) were excluded. Two authors independently reviewed all identified titles and abstracts for eligibility. Nine articles were identified as meeting the inclusion criteria. Four studies measured transfer of simulation-based CRM learning into the clinical setting (Kirkpatrick Level 3). In three of these studies, simulation-enhanced CRM training was found significantly more effective than no intervention or didactic teaching. Five studies measured patient outcomes (Kirkpatrick Level 4). Only one of these studies found that simulation-based CRM training made a clearly significant impact on patient mortality. Based on a small number of studies, this systematic review found that CRM skills learned at the simulation centre are transferred to clinical settings, and the acquired CRM skills may translate to improved patient outcomes, including a decrease in mortality.

    To gain a better understanding of factors influencing clinicians' embryo transfer practices. Cross-sectional survey. Web-based survey conducted in December 2008 of individuals practicing IVF in centers registered with the Society for Assisted Reproductive Technology (SART). None. None. Prevalence of clinicians reporting following embryo transfer guidelines recommended by the American Society for Reproductive Medicine (ASRM), prevalence among these clinicians to deviate from ASRM guidelines in commonly encountered clinical scenarios, and practice patterns related to single embryo transfer. Six percent of respondents reported following their own, independent guidelines for the number of embryos to transfer after IVF. Of the 94% of respondents who reported routinely following ASRM embryo transfer guidelines, 52% would deviate from these guidelines for patient request, 51% for cycles involving the transfer of frozen embryos, and 70% for patients with previously failed IVF cycles. All respondents reported routinely discussing the risks of multiple gestations associated with standard embryo transfer practices, whereas only 34% reported routinely discussing single embryo transfer with all patients. Although the majority of clinicians responding to our survey reported following ASRM embryo transfer guidelines, at least half would deviate from these guidelines in a number of different situations.

  17. Method for eliminating artifacts in CCD imagers

    Turko, B.T.; Yates, G.J.

    1992-06-09

    An electronic method for eliminating artifacts in a video camera employing a charge coupled device (CCD) as an image sensor is disclosed. The method comprises the step of initializing the camera prior to normal read out and includes a first dump cycle period for transferring radiation generated charge into the horizontal register while the decaying image on the phosphor being imaged is being integrated in the photosites, and a second dump cycle period, occurring after the phosphor image has decayed, for rapidly dumping unwanted smear charge which has been generated in the vertical registers. Image charge is then transferred from the photosites and to the vertical registers and read out in conventional fashion. The inventive method allows the video camera to be used in environments having high ionizing radiation content, and to capture images of events of very short duration and occurring either within or outside the normal visual wavelength spectrum. Resultant images are free from ghost, smear and smear phenomena caused by insufficient opacity of the registers and, and are also free from random damage caused by ionization charges which exceed the charge limit capacity of the photosites. 3 figs.

  18. LSI arrays for space stations

    NASA Technical Reports Server (NTRS)

    Gassaway, J. D.

    1976-01-01

    Two approaches have been taken to study CCD's and some of their fundamental limitations. First a numerical analysis approach has been developed to solve the coupled transport and Poisson's equation for a thorough analysis of charge transfer in a CCD structure. The approach is formulated by treating the minority carriers as a surface distribution at the Si-SiO2 interface and setting up coupled difference equations for the charge and the potential. The SOR method is proposed for solving the two dimensional Poisson's equation for the potential. Methods are suggested for handling the discontinuities to improve convergence. Second, CCD shift registers were fabricated with parameters which should allow complete charge transfer independent of the transfer electrode gap width. A test instrument was designed and constructed which can be used to test this, or any similar, three phase CCD shift register.

  19. Nurses' participation in personal knowledge transfer: the role of leader-member exchange (LMX) and structural empowerment.

    PubMed

    Davies, Alicia; Wong, Carol A; Laschinger, Heather

    2011-07-01

    The purpose of this study was to test Kanter's theory by examining relationships among structural empowerment, leader-member exchange (LMX) quality and nurses' participation in personal knowledge transfer activities. Despite the current emphasis on evidence-based practice in health care, research suggests that implementation of research findings in everyday clinical practice is unsystematic at best with mixed outcomes. This study was a secondary analysis of data collected using a non-experimental, predictive mailed survey design. A random sample of 400 registered nurses who worked in urban tertiary care hospitals in Ontario yielded a final sample of 234 for a 58.5% response rate. Hierarchical multiple linear regression analysis revealed that the combination of LMX and structural empowerment accounted for 9.1% of the variance in personal knowledge transfer but only total empowerment was a significant independent predictor of knowledge transfer (β=0.291, t=4.012, P<0.001). Consistent with Kanter's Theory, higher levels of empowerment and leader-member exchange quality resulted in increased participation in personal knowledge transfer in practice. The results reinforce the pivotal role of nurse managers in supporting empowering work environments that are conducive to transfer of knowledge in practice to provide evidence-based care. © 2011 The Authors.

    Acute malnutrition is a public health issue worldwide, and particularly in the Eastern region of Burkina Faso. Following a needs assessment, unconditional seasonal, multiannual cash transfers were implemented as a safety net to prevent childhood undernutrition. The objectives of this study were to explore the types of purchases made by beneficiaries of this cash transfer program and to understand the perceived effects of and changes induced by regular cash transfers in the daily lives of women, and at the household and community level. The design of this study was a two-arm cluster randomized controlled trial. Qualitative data were collected each month during the cash transfer period for two years, leading to a total of more than 300 interviews and focus group discussions with various participants: beneficiary mothers, heads of households, mothers-in-law, co-wives, key members of the community, and participants of the control group. The two main types of expenses reported were food and health care for the child and the whole family. The program was also associated with positive perceived changes at the household level, mainly related to gender equality and improvement of women's status, and has promoted an increase in dignity and social integration of the poorest at the community level through cash sharing. Unexpected effects of this program included some women planning new pregnancies and some individuals not expecting the transfers to end. Although the transfers were unconditional, the cash was mainly used to improve the children's and households' food security and health, which correspond to two main underlying causes of undernutrition. Therefore, spending mainly in these areas can help to prevent undernutrition in children. ClinicalTrials.gov , identifier: NCT01866124 , registered May 7, 2013.

Resultant images are free from ghost, smear and smear phenomena caused by insufficient opacity of the registers (28) and (32), and are also free from random damage caused by ionization charges which exceed the charge limit capacity of the photosites (36) and (37).

  16. Ultrasound-Guided Regional Anesthesia Simulation Training: A Systematic Review.

    PubMed

    Chen, Xiao Xu; Trivedi, Vatsal; AlSaflan, AbdulHadi A; Todd, Suzanne Clare; Tricco, Andrea C; McCartney, Colin J L; Boet, Sylvain

    Ultrasound-guided regional anesthesia (UGRA) has become the criterion standard of regional anesthesia practice. Ultrasound-guided regional anesthesia teaching programs often use simulation, and guidelines have been published to help guide URGA education. This systematic review aimed to examine the effectiveness of simulation-based education for the acquisition and maintenance of competence in UGRA. Studies identified in MEDLINE, EMBASE, CINAHL, Cochrane Central Register of Controlled Trials, and ERIC were included if they assessed simulation-based UGRA teaching with outcomes measured at Kirkpatrick level 2 (knowledge and skills), 3 (transfer of learning to the workplace), or 4 (patient outcomes). Two authors independently reviewed all identified references for eligibility, abstracted data, and appraised quality. After screening 176 citations and 45 full-text articles, 12 studies were included. Simulation-enhanced training improved knowledge acquisition (Kirkpatrick level 2) when compared with nonsimulation training. Seven studies measuring skill acquisition (Kirkpatrick level 2) found that simulation-enhanced UGRA training was significantly more effective than alternative teaching methods or no intervention. One study measuring transfer of learning into the clinical setting (Kirkpatrick level 3) found no difference between simulation-enhanced UGRA training and non-simulation-based training. However, this study was discontinued early because of technical challenges. Two studies examined patient outcomes (Kirkpatrick level 4), and one of these found that simulation-based UGRA training improved patient outcomes compared with didactic teaching. Ultrasound-guided regional anesthesia knowledge and skills significantly improved with simulation training. The acquired UGRA skills may be transferred to the clinical setting; however, further studies are required to confirm these changes translate to improved patient outcomes.

  19. AMICAL: An aid for architectural synthesis and exploration of control circuits

    NASA Astrophysics Data System (ADS)

    Park, Inhag

    AMICAL is an architectural synthesis system for control flow dominated circuits. A behavioral finite state machine specification, where the scheduling and register allocation were performed, is presented. An abstract architecture specification that may feed existing silicon compilers acting at the logic and register transfer levels is described. AMICAL consists of five main functions allowing automatic, interactive and manual synthesis, as well as the combination of these methods. These functions are a synthesizer, a graphics editor, a verifier, an evaluator, and a documentor. Automatic synthesis is achieved by algorithms that allocate both functional units, stored in an expandable user defined library, and connections. AMICAL also allows the designer to interrupt the synthesis process at any stage and make interactive modifications via a specially designed graphics editor. The user's modifications are verified and evaluated to ensure that no design rules are broken and that any imposed constraints are still met. A documentor provides the designer with status and feedback reports from the synthesis process.

  3. A multiscale simulation technique for molecular electronics: design of a directed self-assembled molecular n-bit shift register memory device.

    PubMed

    Lambropoulos, Nicholas A; Reimers, Jeffrey R; Crossley, Maxwell J; Hush, Noel S; Silverbrook, Kia

    2013-12-20

    A general method useful in molecular electronics design is developed that integrates modelling on the nano-scale (using quantum-chemical software) and on the micro-scale (using finite-element methods). It is applied to the design of an n-bit shift register memory that could conceivably be built using accessible technologies. To achieve this, the entire complex structure of the device would be built to atomic precision using feedback-controlled lithography to provide atomic-level control of silicon devices, controlled wet-chemical synthesis of molecular insulating pillars above the silicon, and controlled wet-chemical self-assembly of modular molecular devices to these pillars that connect to external metal electrodes (leads). The shift register consists of n connected cells that read data from an input electrode, pass it sequentially between the cells under the control of two external clock electrodes, and deliver it finally to an output device. The proposed cells are trimeric oligoporphyrin units whose internal states are manipulated to provide functionality, covalently connected to other cells via dipeptide linkages. Signals from the clock electrodes are conveyed by oligoporphyrin molecular wires, and μ-oxo porphyrin insulating columns are used as the supporting pillars. The developed multiscale modelling technique is applied to determine the characteristics of this molecular device, with in particular utilization of the inverted region for molecular electron-transfer processes shown to facilitate latching and control using exceptionally low energy costs per logic operation compared to standard CMOS shift register technology.

    To provide multimodal biomedical images automatically, we constructed the research-oriented image registry, Data Delivery System (DDS). DDS was constructed on the campus local area network. Machines which generate images (imagers: DSA, ultrasound, PET, MRI, SPECT and CT) were connected to the campus LAN. Once a patient is registered, all his images are automatically picked up by DDS as they are generated, transferred through the gateway server to the intermediate server, and copied into the directory of the user who registered the patient. DDS informs the user through e-mail that new data have been generated and transferred. Data format is automatically converted into one which is chosen by the user. Data inactive for a certain period in the intermediate server are automatically achieved into the final and permanent data server based on compact disk. As a soft link is automatically generated through this step, a user has access to all (old or new) image data of the patient of his interest. As DDS runs with minimal maintenance, cost and time for data transfer are significantly saved. By making the complex process of data transfer and conversion invisible, DDS has made it easy for naive-to-computer researchers to concentrate on their biomedical interest.

    Guo, Weiqiang; Jin, Longxu; Xiong, Jingwu

    2008-03-01

    This paper describes a high-frame rate CCD camera capable of operating at 100 frames/s. This camera utilizes Kodak KAI-0340, an interline transfer CCD with 640(vertical)×480(horizontal) pixels. Two output ports are used to read out CCD data and pixel rates approaching 30 MHz. Because of its reduced effective opacity of vertical charge transfer registers, interline transfer CCD can cause undesired image artifacts, such as random white spots and smear generated in the registers. To increase frame rate, a kind of speed-up structure has been incorporated inside KAI-0340, then it is vulnerable to a vertical stripe effect. The phenomena which mentioned above may severely impair the image quality. To solve these problems, some electronic methods of eliminating these artifacts are adopted. Special clocking mode can dump the unwanted charge quickly, then the fast readout of the images, cleared of smear, follows immediately. Amplifier is used to sense and correct delay mismatch between the dual phase vertical clock pulses, the transition edges become close to coincident, so vertical stripes disappear. Results obtained with the CCD camera are shown.

    2001-01-01

    The SIRTF Science Center's (SSC) Science Operations System (SOS) has to contend with nearly one hundred critical operations files via comprehensive file management services. The management is accomplished via the registered file system (otherwise known as TFS) which manages these files in a registered file repository composed of a virtual file system accessible via a TFS server and a file registration database. The TFS server provides controlled, reliable, and secure file transfer and storage by registering all file transactions and meta-data in the file registration database. An API is provided for application programs to communicate with TFS servers and the repository. A command line client implementing this API has been developed as a client tool. This paper describes the architecture, current implementation, but more importantly, the evolution of these services based on evolving community use cases and emerging information system technology.

This was a retrospective and observational study to triages making from January to March 2012 in Pediatric Emergency Department of tertiary hospital in Madrid. The collection data included variables from Pediatric Canadian Triage with five levels, triage tool using in the unit. 6443 triages were evaluated. The most common mistakes was: not to register pain level, 1445 (22.4%); not to register hydration level, 377 (5.9%); principal symptoms inappropriate, 232 (3.6%). Didn't indicate pain level 140 (5.6%) nurses with 12 hour formal training on triage; 492 (14.5%) with training in the unit, and 92 (16.3%) without training in the last year (p < 0.001). Among the nurses working in the unit more than 7 years did not register pain level 472 (12.3%), identified inappropriate principal symptoms 197 (5%) and did not register hydration level 296 (7.7%). The triage education favors better adaptation in the triage assignment. The most common errors are: not to register level pain and hydration when it's needed for the principal symptoms.

  2. Carbon-, sulfur-, and phosphorus-based charge transfer reactions in inductively coupled plasma-atomic emission spectrometry

    NASA Astrophysics Data System (ADS)

    Grindlay, Guillermo; Gras, Luis; Mora, Juan; de Loos-Vollebregt, Margaretha T. C.

    2016-01-01

    In this work, the influence of carbon-, sulfur-, and phosphorus-based charge transfer reactions on the emission signal of 34 elements (Ag, Al, As, Au, B, Ba, Be, Ca, Cd, Co, Cr, Cu, Fe, Ga, Hg, I, In, Ir, K, Li, Mg, Mn, Na, Ni, P, Pb, Pd, Pt, S, Sb, Se, Sr, Te, and Zn) in axially viewed inductively coupled plasma-atomic emission spectrometry has been investigated. To this end, atomic and ionic emission signals for diluted glycerol, sulfuric acid, and phosphoric acid solutions were registered and results were compared to those obtained for a 1% w w- 1 nitric acid solution. Experimental results show that the emission intensities of As, Se, and Te atomic lines are enhanced by charge transfer from carbon, sulfur, and phosphorus ions. Iodine and P atomic emission is enhanced by carbon- and sulfur-based charge transfer whereas the Hg atomic emission signal is enhanced only by carbon. Though signal enhancement due to charge transfer reactions is also expected for ionic emission lines of the above-mentioned elements, no experimental evidence has been found with the exception of Hg ionic lines operating carbon solutions. The effect of carbon, sulfur, and phosphorus charge transfer reactions on atomic emission depends on (i) wavelength characteristics. In general, signal enhancement is more pronounced for electronic transitions involving the highest upper energy levels; (ii) plasma experimental conditions. The use of robust conditions (i.e. high r.f. power and lower nebulizer gas flow rates) improves carbon, sulfur, and phosphorus ionization in the plasma and, hence, signal enhancement; and (iii) the presence of other concomitants (e.g. K or Ca). Easily ionizable elements reduce ionization in the plasma and consequently reduce signal enhancement due to charge transfer reactions.

  6. Formal verification of an avionics microprocessor

    NASA Technical Reports Server (NTRS)

    Srivas, Mandayam, K.; Miller, Steven P.

    1995-01-01

    Formal specification combined with mechanical verification is a promising approach for achieving the extremely high levels of assurance required of safety-critical digital systems. However, many questions remain regarding their use in practice: Can these techniques scale up to industrial systems, where are they likely to be useful, and how should industry go about incorporating them into practice? This report discusses a project undertaken to answer some of these questions, the formal verification of the AAMPS microprocessor. This project consisted of formally specifying in the PVS language a rockwell proprietary microprocessor at both the instruction-set and register-transfer levels and using the PVS theorem prover to show that the microcode correctly implemented the instruction-level specification for a representative subset of instructions. Notable aspects of this project include the use of a formal specification language by practicing hardware and software engineers, the integration of traditional inspections with formal specifications, and the use of a mechanical theorem prover to verify a portion of a commercial, pipelined microprocessor that was not explicitly designed for formal verification.

Thus, the government's policy regarding nursing staffing has a practical impact, and better policies could lead to more appropriate nurse staffing. The actual evaluation of the government-recommended staffing levels in Korea is paramount for the establishment of a realistic and effective system that promotes quality care and patient safety. The participating hospital operated under the government-recommended staffing levels (Grade 2 of the Graded Fee of Nursing Management Inpatient System). For unit-level evaluations, one surgical unit was chosen and its staffing level was changed by assigning one additional registered nurse for 6 months. Length of hospitalisation, incidents of death, overtime hours and nursing job performance were measured prior to and after the addition of the extra staff. After 6 months, the length of patient hospitalisation and registered nurse overtime hours reduced and nurse job performance scores in the unit analysed improved. The results demonstrated that increasing the number of registered nurses beyond the current government-recommended staffing level improves patient and nurse outcomes. This indicates the importance and value of empirically assessing the need for changes in the recommended nurse staffing levels to develop appropriate, realistic and effective policies. © 2013 John Wiley & Sons Ltd.

  10. Quantum Darwinism and non-Markovian dissipative dynamics from quantum phases of the spin-1/2 X X model

    Quantum Darwinism explains the emergence of a classical description of objects in terms of the creation of many redundant registers in an environment containing their classical information. This amplification phenomenon, where only classical information reaches the macroscopic observer and through which different observers can agree on the objective existence of such object, has been revived lately for several types of situations, successfully explaining classicality. We explore quantum Darwinism in the setting of an environment made of two level systems which are initially prepared in the ground state of the XX model, which exhibits different phases; we find that the different phases have different abilities to redundantly acquire classical information about the system, the "ferromagnetic phase" being the only one able to complete quantum Darwinism. At the same time we relate this ability to how non-Markovian the system dynamics is, based on the interpretation that non-Markovian dynamics is associated with backflow of information from environment to system, thus spoiling the information transfer needed for Darwinism. Finally, we explore mixing of bath registers by allowing a small interaction among them, finding that this spoils the stored information as previously found in the literature.

  11. SU-E-J-129: A Strategy to Consolidate the Image Database of a VERO Unit Into a Radiotherapy Management System

    2014-06-01

    Purpose: To present a strategy to integrate the imaging database of a VERO unit with a treatment management system (TMS) to improve clinical workflow and consolidate image data to facilitate clinical quality control and documentation. Methods: A VERO unit is equipped with both kV and MV imaging capabilities for IGRT treatments. It has its own imaging database behind a firewall. It has been a challenge to transfer images on this unit to a TMS in a radiation therapy clinic so that registered images can be reviewed remotely with an approval or rejection record. In this study, a software system, iPump-VERO,more » was developed to connect VERO and a TMS in our clinic. The patient database folder on the VERO unit was mapped to a read-only folder on a file server outside VERO firewall. The application runs on a regular computer with the read access to the patient database folder. It finds the latest registered images and fuses them in one of six predefined patterns before sends them via DICOM connection to the TMS. The residual image registration errors will be overlaid on the fused image to facilitate image review. Results: The fused images of either registered kV planar images or CBCT images are fully DICOM compatible. A sentinel module is built to sense new registered images with negligible computing resources from the VERO ExacTrac imaging computer. It takes a few seconds to fuse registered images and send them to the TMS. The whole process is automated without any human intervention. Conclusion: Transferring images in DICOM connection is the easiest way to consolidate images of various sources in your TMS. Technically the attending does not have to go to the VERO treatment console to review image registration prior delivery. It is a useful tool for a busy clinic with a VERO unit.« less

  12. Information hiding and retrieval in Rydberg wave packets using half-cycle pulses

    DOE Office of Scientific and Technical Information (OSTI.GOV)

    Murray, J. M.; Pisharody, S. N.; Wen, H.

    We demonstrate an information hiding and retrieval scheme with the relative phases between states in a Rydberg wave packet acting as the bits of a data register. We use a terahertz half-cycle pulse (HCP) to transfer phase-encoded information from an optically accessible angular momentum manifold to another manifold which is not directly accessed by our laser pulses, effectively hiding the information from our optical interferometric measurement techniques. A subsequent HCP acting on these wave packets reintroduces the information back into the optically accessible data register manifold which can then be read out.

    To evaluate secondary exposure of testosterone transferred to females from a male partner, dosed with 1.62% testosterone gel after direct skin-to-skin contact with the application site, and to investigate the effect of wearing a t-shirt on testosterone transfer. Across three studies, a total of 72 healthy males applied 5.0 g 1.62% testosterone gel to their abdomen alone, upper arms/shoulders alone, or a combination of their upper arms/shoulders and abdomen (single dose or once daily for 7 days). Male-female contact occurred 2 or 12 hours after testosterone gel application, with males either wearing or not wearing a t-shirt. There were 15 minutes of supervised contact with the application site between the male and his female partner. Blood samples were collected over a 24 hour period in females for assessment of serum testosterone levels at baseline and after contact. Pharmacokinetic parameters included C(max) (maximum serum concentration), AUC(0-24) (area under the serum concentration-time curve from 0-24 hours), and C(av) (time-averaged concentration over the 24-hour period post-contact). Subjects were monitored for adverse events. CLINICAL TRIAL REGISTRATION NCT NUMBERS: Study 1 was not registered (first subject enrolled 8 March 2007); Study 2: 00998933; Study 3, 01130298. Testosterone levels (C(av) and C(max)) in females increased 86-185% from baseline after direct abdominal skin contact, although C(av) levels remained within female eugonadal range. Testosterone concentrations returned to baseline within 48 hours after last skin contact. A t-shirt barrier reduced testosterone transfer by approximately 40-48% when 5.0 g of testosterone gel was applied to the abdomen alone. A t-shirt barrier prevented transfer when 5.0 g of testosterone gel was applied to the upper arms and shoulders or to a combination of the upper arms and shoulders and the abdomen (C(max) and C(av) increased by approximately 5-11%). No major safety events were observed during the studies. There is a risk of testosterone transfer from males using 1.62% testosterone gel to others who come in contact with the application site for at least 12 hours after application. Secondary exposure can be mitigated by means of a t-shirt barrier. Women for these studies were not selected by menopausal status. The study designs were intended to simulate exaggerated conditions of transfer.

  14. Spatial features register: toward standardization of spatial features

    USGS Publications Warehouse

    Cascio, Janette

    1994-01-01

    As the need to share spatial data increases, more than agreement on a common format is needed to ensure that the data is meaningful to both the importer and the exporter. Effective data transfer also requires common definitions of spatial features. To achieve this, part 2 of the Spatial Data Transfer Standard (SDTS) provides a model for a spatial features data content specification and a glossary of features and attributes that fit this model. The model provides a foundation for standardizing spatial features. The glossary now contains only a limited subset of hydrographic and topographic features. For it to be useful, terms and definitions must be included for other categories, such as base cartographic, bathymetric, cadastral, cultural and demographic, geodetic, geologic, ground transportation, international boundaries, soils, vegetation, water, and wetlands, and the set of hydrographic and topographic features must be expanded. This paper will review the philosophy of the SDTS part 2 and the current plans for creating a national spatial features register as one mechanism for maintaining part 2.

    This paper describes the embedded controller used for the multichannel readout system for the GEM detector. The controller is based on the embedded Mini ITX mainboard, running the GNU/Linux operating system. The controller offers two interfaces to communicate with the FPGA based readout system. FPGA configuration and diagnostics is controlled via low speed USB based interface, while high-speed setup of the readout parameters and reception of the measured data is handled by the PCI Express (PCIe) interface. Hardware access is synchronized by the dedicated server written in C. Multiple clients may connect to this server via TCP/IP network, and different priority is assigned to individual clients. Specialized protocols have been implemented both for low level access on register level and for high level access with transfer of structured data with "msgpack" protocol. High level functionalities have been split between multiple TCP/IP servers for parallel operation. Status of the system may be checked, and basic maintenance may be performed via web interface, while the expert access is possible via SSH server. System was designed with reliability and flexibility in mind.

    Medical literature is scarce on information to define a basic skills training program for laparoscopic surgery (peg and transferring, cutting, clipping). The aim of this study was to determine the minimal number of simulator sessions of basic laparoscopic tasks necessary to elaborate an optimal virtual reality training curriculum. Eleven medical students with no previous laparoscopic experience were spontaneously enrolled. They were submitted to simulator training sessions starting at level 1 (Immersion Lap VR, San Jose, CA), including sequentially camera handling, peg and transfer, clipping and cutting. Each student trained twice a week until 10 sessions were completed. The score indexes were registered and analyzed. The total of errors of the evaluation sequences (camera, peg and transfer, clipping and cutting) were computed and thereafter, they were correlated to the total of items evaluated in each step, resulting in a success percent ratio for each student for each set of each completed session. Thereafter, we computed the cumulative success rate in 10 sessions, obtaining an analysis of the learning process. By non-linear regression the learning curve was analyzed. By the non-linear regression method the learning curve was analyzed and a r2 = 0.73 (p < 0.001) was obtained, being necessary 4.26 (∼five sessions) to reach the plateau of 80% of the estimated acquired knowledge, being that 100% of the students have reached this level of skills. From the fifth session till the 10th, the gain of knowledge was not significant, although some students reached 96% of the expected improvement. This study revealed that after five simulator training sequential sessions the students' learning curve reaches a plateau. The forward sessions in the same difficult level do not promote any improvement in laparoscopic basic surgical skills, and the students should be introduced to a more difficult training tasks level.

  15. Impact of ancestry categorisations on residential segregation measures using Swedish register data.

    PubMed

    Jarvis, Benjamin; Kawalerowicz, Juta; Valdez, Sarah

    2017-07-01

    Country-of-birth data contained in registers are often aggregated to create broad ancestry group categories. We examine how measures of residential segregation vary according to levels of aggregation. We use Swedish register data to calculate pairwise dissimilarity indices from 1990 to 2012 for ancestry groups defined at four nested levels of aggregation: (1) micro-groups containing 50 categories, (2) meso-groups containing 16 categories, (3) macro-groups containing six categories and (4) a broad Western/non-Western binary. We find variation in segregation levels between ancestry groups that is obscured by data aggregation. This study demonstrates that the practice of aggregating country-of-birth statistics in register data can hinder the ability to identify highly segregated groups and therefore design effective policy to remedy both intergroup and intergenerational inequalities.

  16. Features of the Upgraded Imaging for Hypersonic Experimental Aeroheating Testing (IHEAT) Software

    NASA Technical Reports Server (NTRS)

    Mason, Michelle L.; Rufer, Shann J.

    2016-01-01

    The Imaging for Hypersonic Experimental Aeroheating Testing (IHEAT) software is used at the NASA Langley Research Center to analyze global aeroheating data on wind tunnel models tested in the Langley Aerothermodynamics Laboratory. One-dimensional, semi-infinite heating data derived from IHEAT are used in the design of thermal protection systems for hypersonic vehicles that are exposed to severe aeroheating loads, such as reentry vehicles during descent and landing procedures. This software program originally was written in the PV-WAVE(Registered Trademark) programming language to analyze phosphor thermography data from the two-color, relative-intensity system developed at Langley. To increase the efficiency, functionality, and reliability of IHEAT, the program was migrated to MATLAB(Registered Trademark) syntax and compiled as a stand-alone executable file labeled version 4.0. New features of IHEAT 4.0 include the options to perform diagnostic checks of the accuracy of the acquired data during a wind tunnel test, to extract data along a specified multi-segment line following a feature such as a leading edge or a streamline, and to batch process all of the temporal frame data from a wind tunnel run. Results from IHEAT 4.0 were compared on a pixel level to the output images from the legacy software to validate the program. The absolute differences between the heat transfer data output from the two programs were on the order of 10(exp -5) to 10(exp -7). IHEAT 4.0 replaces the PV-WAVE(Registered Trademark) version as the production software for aeroheating experiments conducted in the hypersonic facilities at NASA Langley.

  17. The changing roles of registered nurses in Pioneer Accountable Care Organizations.

    PubMed

    Pittman, Patricia; Forrest, Emily

    2015-01-01

    This study focuses on whether and how Pioneer Accountable Care Organization (ACO) leaders believe the deployment of the registered nurse workforce is changing in response to the shared savings incentives. Semistructured phone interviews with leaders from 18 of the original 32 Pioneer ACOs were conducted. Narrative analysis suggests that all of the organizations are developing new and enhanced roles for registered nurses across the continuum of care. Overall, eight types of changes were reported: enhancement of roles, substitution, delegation, increased numbers of nurses, relocation of services, transfer of nurses from one setting to another, the use of liaison nurses across settings, and partnerships between nurses coordinating care in primary and acute care settings. This exploratory study suggests that Pioneer ACO leaders believe that payment models are affecting the deployment of the health workforce and that these changes are, in turn, driving outcomes.

    Paper-based village registers were introduced 5 years ago in Malawi as a tool to measure vital statistics of births and deaths at the population level. However, usage, completeness and accuracy of their content have never been formally evaluated. In Traditional Authority Mwambo, Zomba district, Malawi, we assessed 280 of the 325 village registers with respect to (i) characteristics of village headmen who used village registers, (ii) use and content of village registers, and (iii) whether village registers provided accurate information on births and deaths. All village headpersons used registers. There were 185 (66%) registers that were regarded as 95% completed, and according to the registers, there were 115 840 people living in the villages in the catchment area. In 2011, there were 1753 births recorded in village registers, while 6397 births were recorded in health centre registers in the same catchment area. For the same year, 199 deaths were recorded in village registers, giving crude death rates per 100 000 population of 189 for males and 153 for females. These could not be compared with death rates in health centre registers due to poor and inconsistent recording in these registers, but they were compared with death rates obtained from the 2010 Malawi Demographic Health Survey that reported 880 and 840 per 100 000 for males and females, respectively. In conclusion, this study shows that village registers are a potential source for vital statistics. However, considerable inputs are needed to improve accuracy of births and deaths, and there are no functional systems for the collation and analysis of data at the traditional authority level. Innovative ways to address these challenges are discussed, including the use of solar-powered electronic village registers and mobile phones, connected with each other and the health facilities and the District Commissioner's office through the cellular network and wireless coverage. © 2013 John Wiley & Sons Ltd.

  20. A new method for multi-bit and qudit transfer based on commensurate waveguide arrays

    NASA Astrophysics Data System (ADS)

    Petrovic, J.; Veerman, J. J. P.

    2018-05-01

    The faithful state transfer is an important requirement in the construction of classical and quantum computers. While the high-speed transfer is realized by optical-fibre interconnects, its implementation in integrated optical circuits is affected by cross-talk. The cross-talk between densely packed optical waveguides limits the transfer fidelity and distorts the signal in each channel, thus severely impeding the parallel transfer of states such as classical registers, multiple qubits and qudits. Here, we leverage on the suitably engineered cross-talk between waveguides to achieve the parallel transfer on optical chip. Waveguide coupling coefficients are designed to yield commensurate eigenvalues of the array and hence, periodic revivals of the input state. While, in general, polynomially complex, the inverse eigenvalue problem permits analytic solutions for small number of waveguides. We present exact solutions for arrays of up to nine waveguides and use them to design realistic buses for multi-(qu)bit and qudit transfer. Advantages and limitations of the proposed solution are discussed in the context of available fabrication techniques.

    Processing and analysis of Very High Resolution (VHR) satellite images provide a mass of crucial information, which can be used for urban planning, security issues or environmental monitoring. However, they are computationally expensive and, thus, time consuming, while some of the applications, such as natural disaster monitoring and prevention, require high efficiency performance. Fortunately, parallel computing techniques and embedded systems have made great progress in recent years, and a series of massively parallel image processing devices, such as digital signal processors or Field Programmable Gate Arrays (FPGAs), have been made available to engineers at a very convenient price and demonstrate significant advantages in terms of running-cost, embeddability, power consumption flexibility, etc. In this work, we designed a texture region segmentation method for very high resolution satellite images by using the level set algorithm and the multi-kernel theory in a high-abstraction C environment and realize its register-transfer level implementation with the help of a new proposed high-level synthesis-based design flow. The evaluation experiments demonstrate that the proposed design can produce high quality image segmentation with a significant running-cost advantage. PMID:27240370

    The demographic aging of the Registered Indian population suggests that the social, economic, and health conditions of older Registered Indians will be increasingly important for communities and policymakers. We have adapted the United Nations Development Program's Human Development Index using data from the Census of Canada and the Indian Register to measure whether improvements seen in the knowledge, standard of living, and health of the Registered Indian population between 1981 and 2001 are also observed among Registered Indians of older ages. The absolute levels of well-being of older Registered Indians were found to have improved, but gaps with other older Canadians had widened, particularly in terms of income and male life expectancy.

    We developed a system that transfers images via network and started using them in our hospital's PACS (Picture Archiving and Communication Systems) in 2006. We are pleased to report that the system has been re-developed and has been running so that there will be a regional liaison in the future. It has become possible to automatically transfer images simply by selecting the destination hospital that is registered in advance at the relay server. The gateway of this system can send images to a multi-center, relay management server, which receives the images and resends them. This system has the potential to be useful for image exchange, and to serve as a regional medical liaison.

  5. Transfer of preterm infants from incubator to open cot at lower versus higher body weight.

    New, Karen; Flenady, Vicki; Davies, Mark W

    2011-09-07

    A key criterion for discharging preterm infants home from nurseries is their ability to maintain temperature once transferred from incubators to open cots. The timing of transfer is important given the preterm infant's immature thermoregulatory mechanisms. To determine the effects of body weight in transferring preterm infants from incubators to unheated open cots. Electronic databases, the Cochrane Central Register of Controlled Trials, clinical trials registers and the abstracts of the Society for Pediatric Research were searched. Randomised and quasi-randomised controlled trials comparing transfer of preterm infants from incubators to unheated open cots at lower and higher body weights. Data collection and analysis was performed in accordance with the methods of the Cochrane Neonatal Review Group. Four eligible studies were identified. Two of the identified trials were assessed as having good methodological quality. Two studies reported daily weight gain (calculated as growth velocity); the lower body weight group had a significantly greater daily weight gain [pooled mean difference (MD) 2.66 (95% confidence interval (CI)1.37 to 3.95). One study reported a larger proportion of infants transferred at the higher body weight had an episode of low temperature in the first 72 hours; while no difference between the two groups was found in the proportion of infants experiencing cold stress post-transfer to discharge. Two studies report no difference between the two groups in requiring an overhead heater for temperature maintenance [pooled RR 1.43 (95% CI 0.35 to 1.18). No statistically significant difference was shown for proportion of infants returning to an incubator [three studies (N = 336) [pooled RR 1.78 (95% CI 0.77 to 4.08].Two studies report there was no statistically significant difference in time spent in an open cot post transfer to discharge; while one study found infants transferred at lower weights had a significantly reduced length of stay [MD -9.00 (95% CI -13.29 to -4.71), a second study found no differences between the two groups [MD 0.30 (95% CI -5.11 to 5.71). In these two studies not breastfeeding at discharge was not significantly different between the lower and higher body weight groups [pooled RR 1.02 (95% CI 0.69 to 1.51). Medically stable preterm infants can be transferred to unheated open cots at a lower body weight of 1600 grams without adverse effects on temperature stability or weight gain. Earlier transfer does not necessarily result in earlier discharge.

    Headmix and head registers use cricothyroid (CT) muscle dominant voicing, whereas chest and chestmix registers use thyroarytenoid (TA) muscle dominant voicing. Cross-sectional study. CT and TA electromyographic data obtained from five untrained singers and two trained singers were analyzed to determine CT and TA muscle dominance as a function of register. Simultaneous recordings of TA and CT muscle activity and audio were obtained during production of pitch glides and a variety of midrange and upper pitches in chest, chestmix, headmix, and head registers. TA dominant phonation was only observed for chest productions and headmix/head register productions below 300 Hz. All phonation above 300 Hz, regardless of register, showed CT:TA muscle activity ratios that were CT dominant or close to 1, indicating nearly equal CT and TA muscle activity. This was true for all subjects on all vocal tasks. For the subjects sampled in this study, pitch level appeared to have a greater effect on TA and CT muscle dominance than vocal register. Preliminary findings regarding CT and TA dominance and register control do not support the assumption that all chest and chestmix production has greater TA muscle activity than CT muscle activity or that all headmix and head production require greater CT muscle activity than TA muscle activity. The data indicate that pitch level may play a greater role in determining TA and CT dominance than register. Copyright © 2014 The Voice Foundation. Published by Elsevier Inc. All rights reserved.

    The increasing system complexity of FPGA-based hardware designs and shortening of time-to-market have motivated the adoption of new designing methodologies focused on addressing the current need for high-performance circuits. High-Level Synthesis (HLS) tools can generate Register Transfer Level (RTL) designs from high-level software programming languages. These tools have evolved significantly in recent years, providing optimized RTL designs, which can serve the needs of safety-critical applications that require both high performance and high reliability levels. However, a reliability evaluation of HLS-based designs under soft errors has not yet been presented. In this work, the trade-offs of different HLS-based designs in terms of reliability, resource utilization, and performance are investigated by analyzing their behavior under soft errors and comparing them to a standard processor-based implementation in an SRAM-based FPGA. Results obtained from fault injection campaigns and radiation experiments show that it is possible to increase the performance of a processor-based system up to 5,000 times by changing its architecture with a small impact in the cross section (increasing up to 8 times), and still increasing the Mean Workload Between Failures (MWBF) of the system.

  8. Comparison of IVF cycles reported in a voluntary ART registry with a mandatory registry in Spain.

    Monitoring assisted reproductive technology (ART) is essential to evaluate the performance of fertility treatment and its impact on birth rates. In Europe, there are two kinds of ART registers: voluntary and mandatory. The validity of register data is very important with respect to the quality of register-based observational studies. The aim of this paper is to determine the degree of agreement between voluntary and mandatory ART registers. The two sources for the data compared in this study (referring to 2005 and 2006) were FIVCAT.NET (an official compulsory Assisted Reproduction Registry within the Health Ministry of the Regional Government of Catalonia, to which all authorized clinics, both public and private, performing assisted reproduction in the region are obliged to report) and the register of the Spanish Fertility Society (SEF), to which data are provided on a voluntary basis. The SEF register data were divided into two groups: (i) data from clinics in Catalonia (SEF-CAT); (ii) data from the rest of Spain, excluding Catalonia (SEF-wCAT). The techniques compared were IVF cycle using patients' own eggs (IVF cycle) versus donor egg cycles. For IVF cycles, the voluntary ART register reflected 77.2% of those on the official one, but the corresponding figure was only 34.4% with respect to donated eggs. The variables analysed in the IVF cycle (insemination technique used, patients' age, number of embryos transferred, pregnancy rates, multiple pregnancies and deliveries) were similar in the three groups studied. However, we observed significant differences in donor egg cycles with regard to the insemination technique used, pregnancy rates and multiple pregnancies between the voluntary and the official register. Data from the voluntary ART register for IVF cycles are valid, but those for donor egg cycles are not. Further study is necessary to determine the reasons for this difference.

  9. Immunisation registers in Canada: progress made, current situation, and challenges for the future.

    PubMed

    2012-04-26

    Immunisation registers have the capacity to capture data on the administration of vaccine doses at the individual level within the population and represent an important tool in assessing immunisation coverage and vaccine uptake. In 1999, the National Advisory Committee on Immunization recommended that a network of immunisation registers be established in Canada. The Canadian Immunization Registry Network (CIRN) was established to coordinate the development of standards and facilitate the sharing of knowledge and experience to develop a national network of such registers. In 2003, the National Immunization Strategy identified immunisation registers as an important component in improving national immunisation surveillance. In addition, there has been consistent public and professional interest in a national immunisation register being available and considerable progress has been made in developing technologies to facilitate the capture of immunisation-related data. More specifically, the automated identification of vaccines, through the use of barcodes on vaccines, will facilitate collection of data related to administered vaccine doses. Nevertheless, challenges remain in the implementation of immunisation registers in all Canadian provinces and territories such that Canada still does not currently have a fully functional network of immunisation registers with the capacity to be interoperable between jurisdictions and to allow for data to be captured at the national level.

    Substantial health disparities exist between Māori--the indigenous people of Aotearoa New Zealand--and non-Māori New Zealanders. This article explores the experience and impact of racism on Māori registered nurses within the New Zealand health system. The narratives of 15 Māori registered nurses were analyzed to identify the effects of racism. This Māori nursing cohort and the data on racism form a secondary analysis drawn from a larger research project investigating the experiences of indigenous health workers in New Zealand and Canada. Jones's levels of racism were utilized as a coding frame for the structural analysis of the transcribed Māori registered nurse interviews. Participants experienced racism on institutional, interpersonal, and internalized levels, leading to marginalization and being overworked yet undervalued. Māori registered nurses identified a lack of acknowledgement of dual nursing competencies: while their clinical skills were validated, their cultural skills-their skills in Hauora Māori--were often not. Experiences of racism were a commonality. Racism--at every level--can be seen as highly influential in the recruitment, training, retention, and practice of Māori registered nurses. The nursing profession in New Zealand and other countries of indigenous peoples needs to acknowledge the presence of racism within training and clinical environments as well as supporting indigenous registered nurses to develop and implement indigenous dual cultural-clinical competencies. © The Author(s) 2014.

  12. Educators' expectations of roles, employability and career pathways of registered and enrolled nurses in Australia.

    2016-01-01

    In Australia, like other countries, two levels of nurse are registered for entry to practice. Educational changes for second level nurses in Australia have led to questions regarding roles and career options. This paper reports on interviews with nursing course coordinators to examine educator expectations of roles and career pathways of registered and enrolled nurses. Coordinators of eight degree (registered) and diploma (enrolled) nursing programs were interviewed to determine their opinions on roles and careers that students were prepared for. Transcripts were thematically analysed. Educators reported similar graduate roles, although high acuity care was primarily the role of registered nurses. Career expectations differed with enrolled nurses having limited advancement opportunity, and registered nurses greater career options. Health organisations were unprepared to accommodate increased practice scope of enrolled nurses and limited work practice through policies stipulating who could perform procedures. Organisational health policies need to accommodate increased enrolled nurse skill base. Education of practising nurses is necessary regarding increased scope of enrolled nurse practice to ensure they are used to their full potential. Increasing patient acuity requires more registered nurses, as enrolled nurses are unprepared to care for complex or deteriorating patients. Copyright © 2015 Elsevier Ltd. All rights reserved.

    To apply lean thinking in triage acuity level-3 patients in order to improve emergency department (ED) throughtput and waiting time. A prospective interventional study. An ED of a tertiary care hospital. Triage acuity level-3 patients. To apply lean techniques such as value stream mapping, workplace organization, reduction of wastes and standardization by the frontline staff. Two periods were compared: (i) pre-lean: April-September, 2015; and (ii) post-lean: April-September, 2016. Variables included: median process time (time from beginning of nurse preparation to the end of nurse finalization after doctor disposition) of both discharged and transferred to observation patients; median length of stay; median waiting time; left without being seen, 72-h revisit and mortality rates, and daily number of visits. There was no additional staff or bed after lean implementation. Despite an increment in the daily number of visits (+8.3%, P < 0.001), significant reductions in process time of discharged (182 vs 160 min, P < 0.001) and transferred to observation (186 vs 176 min, P < 0.001) patients, in length of stay (389 vs 329 min, P < 0.001), and in waiting time (71 vs 48 min, P < 0.001) were achieved after lean implementation. No significant differences were registered in left without being seen rate (5.23% vs 4.95%), 72-h revisit rate (3.41% vs 3.93%), and mortality rate (0.23% vs 0.15%). Lean thinking is a methodology that can improve triage acuity level-3 patient flow in the ED, resulting in better throughput along with reduced waiting time.

    This is a multi-center, hospital-based study aiming to estimate social factors influencing pre-hospital times of arrival in acute ischemic stroke, with a perspective of finding ways to reduce arrival time and to augment the number of patients eligible for intra-arterial thrombolysis. Acute ischemic stroke patients who presented at the emergency units of four major general public hospitals were registered. We assessed information concerning demographics, time of presentation, clinical situation, imaging, treatment, and socioeconomic factors. The sample was divided in two sub-samples, based on the time of arrival since onset of symptoms, and was statistically analyzed. During one calendar year (2005), 907 patients were registered. Among them 34.6% arrived in the first 6 h from symptom onset, 38.7% arrived between 6 and 24 h, 18.1% after 24 h and for 8.6% the time of onset was unknown. Younger age (P = 0.007), transfer with ambulatory service (Ρ = 0.002), living with a mate (Ρ = 0.004), and higher educational level (P < 0.005) were factors which correlated significantly with early arrival at the hospital. Instructing patients at high risk for stroke to live with a housemate appears beneficial for timely arrival at the hospital. The establishment of dedicated acute stroke call and transportation center should improve the percentage of early arrival. A national information campaign is needed to increase the level of awareness of the population concerning beneficial social behaviors and optimal reaction to symptoms of acute ischemic stroke.

  15. Interventions that promote retention of experienced registered nurses in health care settings: a systematic review.

    Lartey, Sarah; Cummings, Greta; Profetto-McGrath, Joanne

    2014-11-01

    The aim of this review was to report the effectiveness of strategies for retaining experienced Registered Nurses. Nursing researchers have noted that the projected nursing shortage, if not rectified, is expected to affect healthcare cost, job satisfaction and quality patient care. Retaining experienced nurses would help to mitigate the shortage, facilitate the transfer of knowledge and provision of quality care to patients. A systematic review of studies on interventions that promote the retention of experienced Registered Nurses in health care settings. Twelve studies were included in the final analysis. Most studies reported improved retention as a result of the intervention. Team work and individually targeted strategies including mentoring, leadership interest and in-depth orientation increased job satisfaction and produced higher retention results. Few published studies have examined interventions that promote the retention of experienced Registered Nurses in healthcare. Retention was highest when multiple interventions were used. Further research is needed to inform nurse leaders of ways to retain nurses and to maintain quality care in health care settings. Programmes targeting the retention of experienced nurses need to be considered when implementing measures to decrease the nursing shortage and its effects on quality care. © 2013 John Wiley & Sons Ltd.

    To determine consensus across acute care specialty areas on core physical assessment skills necessary for early recognition of changes in patient status in general wards. Current approaches to physical assessment are inconsistent and have not evolved to meet increased patient and system demands. New models of nursing assessment are needed in general wards that ensure a proactive and patient safety approach. A modified Delphi study. Focus group interviews with 150 acute care registered nurses at a large tertiary referral hospital generated a framework of core skills that were developed into a web-based survey. We then sought consensus with a panel of 35 senior acute care registered nurses following a classical Delphi approach over three rounds. Consensus was predefined as at least 80% agreement for each skill across specialty areas. Content analysis of focus group transcripts identified 40 discrete core physical assessment skills. In the Delphi rounds, 16 of these were consensus validated as core skills and were conceptually aligned with the primary survey: (Airway) Assess airway patency; (Breathing) Measure respiratory rate, Evaluate work of breathing, Measure oxygen saturation; (Circulation) Palpate pulse rate and rhythm, Measure blood pressure by auscultation, Assess urine output; (Disability) Assess level of consciousness, Evaluate speech, Assess for pain; (Exposure) Measure body temperature, Inspect skin integrity, Inspect and palpate skin for signs of pressure injury, Observe any wounds, dressings, drains and invasive lines, Observe ability to transfer and mobilise, Assess bowel movements. Among a large and diverse group of experienced acute care registered nurses consensus was achieved on a structured core physical assessment to detect early changes in patient status. Although further research is needed to refine the model, clinical application should promote systematic assessment and clinical reasoning at the bedside. © 2016 John Wiley & Sons Ltd.

    Somatic cell nuclear transfer is a useful tool to maintain genetic information of animals. The Gyeongju Donggyeong dog is a breed registered as natural monument in Korea. The unique feature of the Donggyeong dog is its tail, as the Donggyeong dog can be classified as either short tailed or tailless. The aim of this study was to preserve the Donggyeong dog's unique feature by cloning. Fibroblasts were obtained from a short-tailed Donggyeong dog. In vivo matured oocytes were enucleated, microinjected with a donor cell and fused electrically. Reconstructed embryos were transferred to six recipient dogs. One surrogate became pregnant, and one short-tailed Donggyeong dog was delivered. This study demonstrated that the phenotype of the Donggyeong dog could be conserved by somatic cell nuclear transfer.

    The activity concentrations of certain radionuclides were quantified in some plant foods cultivated around Kudankulam, where a mega-nuclear power plant is being established. The activity concentrations were found more in the 'pulses' group and were the lowest in 'other vegetable' category. The annual effective dose was computed based on the activity concentration of radionuclides and it was found to be higher due to the consumption of cereals and pulses. Other vegetables, cereals, pulses and nuts recorded high transfer factors for the radionuclide (228)Ra. Fruits, leafy vegetables, tubers and roots, and palm embryo registered high transfer factors for (226)Ra. Group-wise activity concentration, radiation dose to the public and soil-plant-to-transfer factor are discussed in detail. Copyright © 2012 Elsevier Ltd. All rights reserved.

  5. Requirements for facilities transferring or receiving select agents. Final rule.

    PubMed

    2001-08-31

    CDC administers regulations that govern the transfer of certain biological agents and toxins ("select agents"). These regulations require entities that transfer or receive select agents to register with CDC and comply with biosafety standards contained in the Third Edition of the CDC/NIH publication "Biosafety in Microbiological and Biomedical Laboratories ("BMBL")." On October 28,1999, CDC published a Notice of Proposed Rulemaking ("NPRM") seeking both to revise the biosafety standards facilities must follow when handling select agents and to provide new biosecurity standards for such facilities. These new standards are contained in the Fourth Edition of BMBL, which the NPRM proposed to incorporate by reference, thereby replacing the Third Edition. No comments were received in response to this proposal. CDC is therefore amending its regulations to incorporate the Fourth Edition.

    Transfers between neonatal units are significant transitional experiences for parents of preterm infants. The study aimed to investigate practices that nurses identify as supportive to parents during preterm infants' transfers. It explored the influence of organisational context on practice and what strategies nurses perceive would help them to provide supportive care. Parents' experiences of neonatal nurseries, their stressors and needs have been well documented. The powerful position of nurses in influencing parenting experience is also recognised. However, nurses' understanding of the transfer process, their roles in supporting parents through this and the organisational context influencing practice have not been explored. A focus group design was used composed of registered nurses from two neonatal units who met for a series of group interviews. Eleven registered nurses participated. They explored and critiqued their current practices and then established aims and strategies for practice development. A qualitative content analysis was conducted. Participants identified validation, empowerment and communication as critical to effective practice. They identified a range of organisational dynamics, from logistical issues to nursing authority and scope of practice, as these influenced practice. They presented strategies for practice development, including staff education and the development of nurse practitioner roles. This study explores nurses' understanding and insights into transitions for parents of preterm infants. It shows a congruence between nurses' perceptions of parents' experiences and needs and those reported by parents in previous studies. It articulates the way nurses practice in response to these perceptions, and the manner in which organisational dynamics influence their ability to facilitate transitions. The need to invest in transitions and invest in nurses to facilitate transitions is proposed, ultimately by increasing their clinical authority and autonomy.

    Low socioeconomic status and poor education elevate the risk of developing esophageal- and junctional cancer. High education level also increases survival after curative surgery. The present study aimed to investigate associations, if any, between patient education-level and treatment allocation after diagnosis of esophageal- and junctional cancer and its subsequent impact on survival. A nation-wide cohort study was undertaken. Data from a Swedish national quality register for esophageal cancer (NREV) was linked to the National Cancer Register, National Patient Register, Prescribed Drug Register, Cause of Death Register and educational data from Statistics Sweden. The effect of education level (low; ≤9 years, intermediate; 10-12 years and high >12 years) on the probability of allocation to curative treatment was analyzed with logistic regression. The Kaplan-Meier-method and Cox proportional hazard models were used to assess the effect of education on survival. A total of 4112 patients were included. In a multivariate logistic regression model, high education level was associated with greater probability of allocation to curative treatment (adjusted OR: 1.48, 95% CI: 1.08-2.03, p = 0,014) as was adherence to a multidisciplinary treatment-conference (adjusted OR: 3.13, 95% CI: 2.40-4.08, p < 0,001). High education level was associated with improved survival in the patients allocated to curative treatment (HR: 0.82, 95% CI: 0.69-0.99, p = 0,036). In this nation-wide cohort of esophageal- and junctional cancer patients, including data regarding many confounders, high education level was associated with greater probability of being offered curative treatment and improved survival.

    Cancer quality registers are attracting increasing attention as important, but still underutilized sources of clinical data. To optimize the use of registers in quality assurance and improvement, data have to be rapidly collected, collated and presented as actionable, at-a-glance information to the reporting departments. This article presents a dashboard performance report on select quality indicators to cancer care providers. Ten quality indicators registered on an individual patient level in the National Prostate Cancer Register of Sweden and recommended by the National Prostate Cancer Guidelines were selected. Data reported to the National Prostate Cancer Register are uploaded within 24 h to the Information Network for Cancer Care platform. Launched in 2014, "What''s Going On, Prostate Cancer" provides rapid, at-a-glance performance feedback to care providers. The indicators include time to report to the National Prostate Cancer Register, waiting times, designated clinical nurse specialist, multidisciplinary conference, adherence to guidelines for diagnostic work-up and treatment, and documentation and outcome of treatment. For each indicator, three performance levels were defined. What's Going On, a dashboard performance report on 10 selected quality indicators to cancer care providers, provides an example of how data in cancer quality registers can be transformed into condensed, at-a-glance information to be used as actionable metrics for quality assurance and improvement.

    In this paper, we report, to the best of our knowledge, a unique field-programmable gate array (FPGA)-based reconfigurable processor for real-time interlaced co-registered ultrasound and photoacoustic imaging and its application in imaging tumor dynamic response. The FPGA is used to control, acquire, store, delay-and-sum, and transfer the data for real-time co-registered imaging. The FPGA controls the ultrasound transmission and ultrasound and photoacoustic data acquisition process of a customized 16-channel module that contains all of the necessary analog and digital circuits. The 16-channel module is one of multiple modules plugged into a motherboard; their beamformed outputs are made available for a digital signal processor (DSP) to access using an external memory interface (EMIF). The FPGA performs a key role through ultrafast reconfiguration and adaptation of its structure to allow real-time switching between the two imaging modes, including transmission control, laser synchronization, internal memory structure, beamforming, and EMIF structure and memory size. It performs another role by parallel accessing of internal memories and multi-thread processing to reduce the transfer of data and the processing load on the DSP. Furthermore, because the laser will be pulsing even during ultrasound pulse-echo acquisition, the FPGA ensures that the laser pulses are far enough from the pulse-echo acquisitions by appropriate time-division multiplexing (TDM). A co-registered ultrasound and photoacoustic imaging system consisting of four FPGA modules (64-channels) is constructed, and its performance is demonstrated using phantom targets and in vivo mouse tumor models.

  11. Effect of crosstalk on QBER in QKD in urban telecommunication fiber lines

    Quantum key distribution (QKD) as a technology is being actively implemented into existing urban telecommunication networks. QKD devices are commercially available products. While sending single photons through optical fiber, adjacent fibers, which are used to transfer classical information, might influence the amount of registrations of single photon detectors. This influence is registered, since it directly introduces a higher quantum bit error rate (QBER) into the final key [1-3]. Our report presents the results of the first tests of the QKD device, developed in the Russian Quantum Center. These tests were conducted in Moscow, and are the first of such a device in Russia in urban optical fiber telecommunication networks. The device in question is based on a two-pass auto-compensating optical scheme, which provides stable single photon transfer through urban optical fiber telecommunication networks [4,5]. The single photon detectors ID230 by ID Quantique were used. They operate in free-running mode, and with a quantum effectiveness of 10 % have a dark count 10 Hz. The background signal level in the dedicated fiber was no less than 5.6•10-14 W, which corresponds to 4.4•104 detector clicks per second. The single mode fiber length in Moscow was 30.6 km, the total attenuation equal to 11.7 dB. The sifted quantum key bit rate reached values of 1.9 kbit/s with the QBER level equal to 5.1 %. Methods of lowering the influence of crosstalk on the QBER are considered.

    Aerosols play an important role in radiative transfer processes involved in different fields of study. In particular, their influence is crucial in the attenuation of light at astronomical and astrophysical observatories, and has to be taken into account in light transfer models employed to reconstruct the signals. The Andean Argentinean region is increasingly being considered as a good candidate to host such facilities, as well as the ones for solar-energy resources, and an adequate knowledge of aerosols characteristics there is needed, but it is not always possible due to the vast area involved and the scarce atmospheric data at ground. The aim of this work is to find correlations between aerosol data and particle trajectories that can give an insight into the origin and behaviour of aerosols in this zone and can be employed in situations in which one does not have local aerosol measurements. For this purpose, an aerosol spectrometer and dust monitor (Grimm 1.109) was installed at the Pierre Auger Observatory of ultra-high-energy cosmic rays, to record aerosol concentrations in different size intervals, at surface level. These measurements are analysed and correlated with air mass trajectories obtained from HYSPLIT (NOAA) model calculations. High aerosol concentrations are registered predominantly when air masses have travelled mostly over continental areas, mainly from the NE direction, while low aerosol concentrations are found in correspondence with air masses coming from the Pacific Ocean, from the NW direction. Different size distribution patterns were found for the aerosols depending on their origin: marine or continental. This work shows for the first time the size distribution of aerosols registered at the Pierre Auger Observatory. The correlations found between mass and particle concentrations (total and for different size ranges) and HYSPLIT air mass trajectories, confirm that the latter can be employed as a useful tool to infer the sources, evolution and characteristics of the aerosols.

    We consider two approaches to dark-spin-mediated quantum computing in hybrid solid-state spin architectures. First, we review the notion of eigenmode-mediated unpolarized spin-chain state transfer and extend the analysis to various experimentally relevant imperfections: quenched disorder, dynamical decoherence, and uncompensated long-range coupling. In finite-length chains, the interplay between disorder-induced localization and decoherence yields a natural optimal channel fidelity, which we calculate. Long-range dipolar couplings induce a finite intrinsic lifetime for the mediating eigenmode; extensive numerical simulations of dipolar chains of lengths up to L=12 show remarkably high fidelity despite these decay processes. We further briefly consider the extension of the protocol to bosonic systems of coupled oscillators. Second, we introduce a quantum mirror based architecture for universal quantum computing that exploits all of the dark spins in the system as potential qubits. While this dramatically increases the number of qubits available, the composite operations required to manipulate dark-spin qubits significantly raise the error threshold for robust operation. Finally, we demonstrate that eigenmode-mediated state transfer can enable robust long-range logic between spatially separated nitrogen-vacancy registers in diamond; disorder-averaged numerics confirm that high-fidelity gates are achievable even in the presence of moderate disorder.

  19. The way to a man's heart is through his stomach?: a mixed methods study on causal mechanisms through which cash and in-kind food transfers decreased intimate partner violence.

    Intimate partner violence (IPV) is highly prevalent and has detrimental effects on the physical and mental health of women across the world. Despite emerging evidence on the impacts of cash transfers on intimate partner violence, the pathways through which reductions in violence occur remain under-explored. A randomised controlled trial of a cash and in-kind food transfer programme on the northern border of Ecuador showed that transfers reduced physical or sexual violence by 30 %. This mixed methods study aimed to understand the pathways that led to this reduction. We conducted a mixed methods study that combined secondary analysis from a randomised controlled trial relating to the impact of a transfer programme on IPV with in-depth interviews and focus group discussions with male and female beneficiaries. A sequential analysis strategy was followed, whereby qualitative results guided the choice of variables for the quantitative analysis and qualitative insights were used to help interpret the quantitative findings. We found qualitative and quantitative evidence that the intervention led to reductions in IPV through three pathways operating at the couple, household and individual level: i) reduced day-to-day conflict and stress in the couple; ii) improved household well-being and happiness; and iii) increased women's decision making, self-confidence and freedom of movement. We found little evidence that any type of IPV increased as a result of the transfers. While cash and in-kind transfers can be important programmatic tools for decreasing IPV, the positive effects observed in this study seem to depend on circumstances that may not exist in all settings or programmes, such as the inclusion of a training component. Moreover, the programme built upon rather than challenged traditional gender roles by targeting women as transfer beneficiaries and framing the intervention under the umbrella of food security and nutrition - domains traditionally ascribed to women. Transfers destined for food consumption combined with nutrition training reduced IPV among marginalised households in northern Ecuador. Evidence suggests that these reductions were realised by decreasing stress and conflict, improving household well-being, and enhancing women's decision making, self-confidence and freedom of movement.

    Register shift between the chest and falsetto register is generally studied in the higher-than-speaking pitch range. However, a similar difference can also be produced at speaking pitch level. The shift from breathy "falsetto" phonation to normal chest voice phonation was studied in normal female (pitch range 170-180 Hz) and male (pitch range 94-110 Hz) subjects. The phonations gliding from falsetto to normal chest voice were analyzed using iterative adaptive inverse filtering and electroglottography. Both trained and untrained, as well as female and male subjects, were able to produce an abrupt register shift from soft falsetto to soft chest register phonation. The differences between male and female speakers in the glottal flow waveforms were smaller than expected. The register shift is interpreted in terms of a "critical mass" concept of chest register phonation.

    A special processor was designed to function as a Reed Solomon decoder with throughput data rate in the Mhz range. This data rate is significantly greater than is possible with conventional digital architectures. To achieve this rate, the processor design includes sequential, pipelined, distributed, and parallel processing. The processor was designed using a high level language register transfer language. The RTL can be used to describe how the different processes are implemented by the hardware. One problem of special interest was the development of dependent processes which are analogous to software subroutines. For greater flexibility, the RTL control structure was implemented in ROM. The special purpose hardware required approximately 1000 SSI and MSI components. The data rate throughput is 2.5 megabits/second. This data rate is achieved through the use of pipelined and distributed processing. This data rate can be compared with 800 kilobits/second in a recently proposed very large scale integration design of a Reed Solomon encoder.

    An architecture for a low-cost, low-complexity digital transceiver is presented in this article. The proposed architecture targets the IEEE 802.15.4 standard for short-range wireless personal area networks and has been implemented as a synthesisable VHDL register transfer level description. The system has been evaluated and tested using a Xilinx 90 nm Virtex-4 field-programmable gate array as the target technology. Bit error rate (BER) and error vector magnitude (EVM) have been used as the figures of merit for modem performance. Simulations show that the recommended minimum BER is achieved at E b/N 0 = 8.7 dB, whereas the EVM is 19.5%. The implemented device occupies 10% of the target FPGA and has a normalised maximum power consumption of 44 mW in transmit mode and 53 mW in receiver mode.

    Performance degradation induced by the DC components at the output of real-time analogue-to-digital converter (ADC) is experimentally investigated for optical fast-OFDM receiver. To compensate this degradation, register transfer level (RTL) circuits for real-time digital DC blocker with 20GS/s throughput are proposed and implemented in field programmable gate array (FPGA). The performance of the proposed real-time digital DC blocker is experimentally investigated in a 15Gb/s optical fast-OFDM system with intensity modulation and direct detection over 40 km standard single-mode fibre. The results show that the fixed-point DC blocker has negligible performance penalty compared to the offline floating point one, and can overcome the error floor of the fast OFDM receiver caused by the DC components from the real-time ADC output.

    An FPGA module leverages the previous work from Goddard Space Flight Center (GSFC) relating to NASA s Space Telecommunications Radio System (STRS) project. The STRS SpaceWire FPGA Module is written in the Verilog Register Transfer Level (RTL) language, and it encapsulates an unmodified GSFC core (which is written in VHDL). The module has the necessary inputs/outputs (I/Os) and parameters to integrate seamlessly with the SPARC I/O FPGA Interface module (also developed for the STRS operating environment, OE). Software running on the SPARC processor can access the configuration and status registers within the SpaceWire module. This allows software to control and monitor the SpaceWire functions, but it is also used to give software direct access to what is transmitted and received through the link. SpaceWire data characters can be sent/received through the software interface, as well as through the dedicated interface on the GSFC core. Similarly, SpaceWire time codes can be sent/received through the software interface or through a dedicated interface on the core. This innovation is designed for plug-and-play integration in the STRS OE. The SpaceWire module simplifies the interfaces to the GSFC core, and synchronizes all I/O to a single clock. An interrupt output (with optional masking) identifies time-sensitive events within the module. Test modes were added to allow internal loopback of the SpaceWire link and internal loopback of the client-side data interface.

    Setting: Antiretroviral treatment (ART) Centre in Tumkur district of Karnataka State, India. There is no published information about pre-ART loss to follow-up from India. Objective: To assess the proportion lost to follow-up (defined as not visiting the ART Centre within 1 year of registration) and associated socio-demographic and immunological variables. Design: Retrospective cohort study involving a review of medical records of adult HIV-infected persons (aged ⩾15 years) registered in pre-ART care during January 2010–June 2012. Results: Of 3238 patients registered, 2519 (78%) were eligible for ART, while 719 (22%) were not. Four of the latter were transferred out; the remaining 715 individuals were enrolled in pre-ART care, of whom 290 (41%) were lost to follow-up. Factors associated with loss to follow-up on multivariate analysis included age group ⩾45 years, low educational level, not being married, World Health Organization Stage III or IV and rural residence. Conclusion: About four in 10 individuals in pre-ART care were lost to follow-up within 1 year of registration. This needs urgent attention. Routine cohort analysis in the national programme should include those in pre-ART care to enable improved review, monitoring and supervision. Further qualitative research to ascertain reasons for loss to follow-up is required to design future interventions. PMID:26400698

    A state-level survey of registered nurses confirmed national findings and raised new issues. Findings revealed that while nurses love the intrinsic reward of nursing, they report workplace, relationship, and stress issues which contribute to frustration and exhaustion. These issues may prevent registered nurses from giving the nursing care they desire to deliver, hastening preventable retirement and costly turnover decisions.

    The Norwegian immunisation register, SYSVAK, is a national electronic immunisation register. It became nationwide in 1995. The major aim was to register all vaccinations in the Childhood Immunisation Programme to ensure that all children are offered adequate vaccination according to schedule in the programme, and to secure high vaccination coverage. Notification to SYSVAK is mandatory, based on personal identification numbers. This allows follow up of individual vaccination schedules and linkage of SYSVAK data to other national health registers for information on outcome diagnoses, such as the surveillance system for communicable diseases. Information from SYSVAK is used to determine vaccine coverage in a timely manner. Coverage can be broken down to regional/local levels and used for active surveillance of vaccination coverage and decisions about interventions. During the 2009 influenza A(H1N1)pdm09 pandemic, an adaptation of SYSVAK enabled daily surveillance of vaccination coverage on national and regional levels. Currently, data from SYSVAK are used, among others, in studies on adverse events related to pandemic vaccination. Future challenges include maximising usage of collected data in surveillance and research, and continued improvement of data quality. Immunisation registers are rich sources for high quality surveillance of vaccination coverage, effectiveness, vaccine failure and adverse events, and gold mines for research.

    In the Netherlands, as in many other countries, a paucity of research exists on the attitudes and intentions of medical students toward organ donation. These students are of interest for the effect that increasing medical knowledge might have on the willingness to register as a donor. To examine which factors determine medical students' willingness to register as donors. We conducted a cross-sectional survey among medical students at the University of Amsterdam. Our questionnaire included questions on actual donor registration, motives, knowledge, and attitudes toward donation. To assess which factors were related to self-reported donor registration status, we conducted multivariate logistic regression analyses. We received 506 questionnaires (response rate at least 84%). The majority of respondents (80%) intended to donate organs, while 59% were registered. Self-reported medical knowledge and positive attitudes on donation were independently associated with registering as a donor. A rising study year was associated with registering as a donor; this could be explained by increasing medical knowledge and changing attitudes. The results of our study suggest that willingness to register as a donor increases with a rising level of knowledge on organ donation up to some minimal level. Copyright © 2013.

    The purpose of this paper is to describe the creation, evolution, and implementation of a database of nursing-sensitive and potentially nursing-sensitive indicators, the Military Nursing Outcomes Database (MilNOD). It discusses data quality, utility, and lessons learned. Prospective data collected each shift include direct staff hours by levels (i.e., registered nurse, other licensed and unlicensed providers), staff categories (i.e., military, civilian, contract, and reservist), patient census, acuity, and admissions, discharges, and transfers. Retrospective adverse event data (falls, medication errors, and needle-stick injuries) were collected from existing records. Annual patient satisfaction, nurse work environment, and pressure ulcer and restraint prevalence surveys were conducted. The MilNOD contains shift level data from 56 units in 13 military hospitals and is used to target areas for managerial and clinical performance improvement. This methodology can be modified for use in other healthcare systems. As standard tools for evidence-based management, databases such as MilNOD allow nurse leaders to track the status of nursing and adverse events in their facilities.

    2017-06-01

    According to the original wording of the Regulation on the register of land and buildings of 2001, in the real estate cadastre there was one attribute associated with the use of a building structure - its intended use, which was applicable until the amendment to the Regulation was introduced in 2013. Then, additional attributes were added, i.e. the type of the building according to the Classification of Fixed Assets (KST), the class of the building according to the Polish Classification of Types of Constructions (PKOB) and, at the same time, the main functional use and other functions of the building remained in the Regulation as well. The record data on buildings are captured for the real estate cadastre from other data sets, for example those maintained by architectural and construction authorities. At the same time, the data contained in the cadastre, after they have been entered or changed in the database, are transferred to other registers, such as tax records, or land and mortgage court registers. This study is the result of the analysis of the laws applicable to the specific units and registers. A list of discrepancies in the attributes occurring in the different registers was prepared. The practical part of the study paid particular attention to the legal bases and procedures for entering the function of a building in the real estate cadastre, which is extremely significant, as it is the attribute determining the property tax basis.

    Current trends in renal anaemia management place greater emphasis, and thus increased workload, on the role of the nurse in haemodialysis settings. However, there is little evidence that demonstrates the relationship between nurse staffing and patient outcomes. To describe nurse staffing in haemodialysis settings, its relationship with target levels of renal anaemia management and to describe target level achievement for different ways of organising anaemia management. Cross-sectional audit. Forty (out of 78) haemodialysis centres in Sweden reported quality assurance data. The numbers of bedside registered nurses, licensed nurse assistants and patients undergoing haemodialysis during a predefined morning shift; type of anaemia management and achieved target levels of anaemia management. The mean patient:registered nurse ratio was 2.4 and the mean patient:nurse assistant ratio was 12.8. There were no significant relationships between registered nurse staffing and target level achievement. On average, 45.6% of the patients had haemoglobin within the target levels at centres applying nurse-driven anaemia management, compared with 47.3% at physician-driven centres. These cross-sectional data suggest that renal anaemia outcomes are unrelated to the patient:registered nurse ratio. There is, however, room for improvement in renal anaemia management in the units included in this study, particularly the achievement of target levels of haemoglobin and transferrin saturation. © 2016 European Dialysis and Transplant Nurses Association/European Renal Care Association.

    The prevalence of Gestational Diabetes Mellitus (GDM) is increasing worldwide. Controlling blood sugar levels is fundamental to the management of GDM. Current practice in Norway includes patients registering blood sugar levels in a booklet and receiving verbal and/or written health information. A smartphone application may provide patients individually targeted and easily available advice to control blood sugar levels. The aim of this paper is to document the process of designing and developing a smartphone application (the Pregnant+ app) that automatically transfers blood sugar levels from the glucometer and has information about healthy eating and physical activity. This formative research included expert-group discussions among health professionals, researchers and experts in data privacy and security. User-involvement studies were conducted to discuss prototypes of the app. Results indicated that the content of the application should be easy to understand given the varying degree of patients’ literacy and in line with the information they receive at clinics. The final version of the app incorporated behavior change techniques such as self-monitoring and cues to action. Results from the first round of interactions show the importance of involving expert groups and patients when developing a mobile health-care device. PMID:27417764

    The RAPPER II study investigates the feasibility, safety and acceptability of using the REX self-stabilising robotic exoskeleton in people with spinal cord injury (SCI) who are obligatory wheelchair users. Feasibility is assessed by the completion of transfer into the REX device, competency in achieving autonomous control and completion of upper body exercise in an upright position in the REX device. Safety is measured by the occurrence of serious adverse events. Device acceptability is assessed with a user questionnaire. RAPPER II is a prospective, multi-centre, open label, non-randomised, non-comparative cohort study in people with SCI recruited from neurological rehabilitation centres in the United Kingdom, Australia and New Zealand. This is the planned interim report of the first 20 participants. Each completed a transfer into the REX, were trained to achieve machine control and completed Timed Up and Go (TUG) tests as well as upper body exercises in standing in a single first time session. The time to achieve each task as well as the amount of assistance required was recorded. After finishing the trial tasks a User Experience questionnaire, exploring device acceptability, was completed. All participants could transfer into the REX. The mean transfer time was 439 s. Nineteen completed the exercise regime. Eighteen could achieve autonomous control of the REX, 17 of whom needed either no assistance or the help of just one therapist. Eighteen participants completed at least one TUG test in a mean time of 313 s, 15 with the assistance of just one therapist. The questionnaire demonstrated high levels of acceptability amongst users. There were no Serious Adverse Events. This first interim analysis of RAPPER II shows that it is feasible and safe for people with SCI to use the REX powered assisted walking device to ambulate and exercise in. Participants with tetraplegia and paraplegia could walk and perform a functional exercise program when standing needing only modest levels of assistance in most cases. User acceptability was high.

    Results of assisted reproductive techniques from treatments initiated in Europe during 2005 are presented in this ninth report. Data were mainly collected from existing national registers. From 30 countries, 923 clinics reported 418 111 treatment cycles including: IVF (118 074), ICSI (203 329), frozen embryo replacement (79 140), oocyte donation (ED, 11 475), preimplantation genetic diagnosis/screening (5846) and in vitro maturation (247). Overall, this represents a 13.6% increase since 2004, partly due to inclusion of 28 417 cycles from Turkey. European data on intrauterine insemination using husband/partner's semen (IUI-H) and donor semen (IUI-D) were reported from 21 countries and included 128 908 IUI-H and 20 568 IUI-D cycles. In 16 countries where all clinics reported to the IVF register, 1115 cycles were performed per million inhabitants. For IVF, the clinical pregnancy rates per aspiration and per transfer were 26.9% and 30.3%, respectively. For ICSI, the corresponding rates were 28.5% and 30.9%. After IUI-H, the clinical pregnancy rate was 12.6% per insemination in women <40. After IVF and ICSI, the distribution of transfer of one, two, three and four or more embryos was 20.0%, 56.1%, 21.5% and 2.3%, respectively. Huge differences exist between countries. The distribution of singleton, twin and triplet deliveries after IVF and ICSI was 78.2%, 21.0% and 0.8%, respectively. This gives a total multiple delivery rate of 21.8% compared with 22.7% in 2004 and 23.1% in 2003. In women <40 years of age, IUI-H was associated with a twin and triplet pregnancy rate of 11.0% and 1.1%, respectively. Compared with earlier years, there was an increase in the reported number of ART cycles in Europe. Although fewer embryos were transferred per treatment, there was a marginal increase in pregnancy rates and a reduction in multiple deliveries.

    Despite recent great progress in diagnosis and microsurgical repair, the prognosis in total brachial plexus-avulsion injury remains unfavorable. Insufficient number of donors and unreasonable use of donor nerves might be key factors. To identify an optimal treatment strategy for this condition, we conducted a retrospective review. Seventy-three patients with total brachial plexus avulsion injury were followed up for an average of 7.3 years. Our analysis demonstrated no significant difference in elbow-flexion recovery between phrenic nerve-transfer (25 cases), phrenic nerve-graft (19 cases), intercostal nerve (17 cases), or contralateral C7-transfer (12 cases) groups. Restoration of shoulder function was attempted through anterior accessory nerve (27 cases), posterior accessory nerve (10 cases), intercostal nerve (5 cases), or accessory + intercostal nerve transfer (31 cases). Accessory nerve + intercostal nerve transfer was the most effective method. A significantly greater amount of elbow extension was observed in patients with intercostal nerve transfer (25 cases) than in those with contralateral C7 transfer (10 cases). Recovery of median nerve function was noticeably better for those who received entire contralateral C7 transfer (33 cases) than for those who received partial contralateral C7 transfer (40 cases). Wrist and finger extension were reconstructed by intercostal nerve transfer (31 cases). Overall, the recommended surgical treatment for total brachial plexus-avulsion injury is phrenic nerve transfer for elbow flexion, accessory nerve + intercostal nerve transfer for shoulder function, intercostal nerves transfer for elbow extension, entire contralateral C7 transfer for median nerve function, and intercostal nerve transfer for finger extension. The trial was registered at ClinicalTrials.gov (identifier: NCT03166033). PMID:29623932

    The aim of the study was to detect changes in the levels of ferritin heavy chain (FHC), ferritin light chain (FLC), and transferrin in the cerebrospinal fluid (CSF) and serum of amyotrophic lateral sclerosis (ALS) patients and to analyze the correlations between the levels of these proteins and various clinical parameters. Cerebrospinal fluid and serum samples were obtained from 54 ALS patients and 46 non-inflammatory neurological disease control (non-INDC) patients. CSF and serum FHC, FLC, and transferring levels were measured via the enzyme-linked immunosorbent method using a commercial ELISA kit, and the times from onset (durations), ALS functional rating scale-revised (ALSFRS-r) scores, and disease progression rates (DPRs) were analyzed by registered neurologists. Statistical analysis was performed via Prism software. Compared with controls, ALS patients exhibited significantly increased FHC and FLC levels in CSF, which were positively correlated with DPR and negatively correlated with duration. Serum transferrin levels were significantly increased in ALS patients but were not correlated with disease progression. FHC and FLC in CSF rapidly increased as the disease worsened. This study demonstrated that the clinical measurement of FHC and FLC in CSF may be beneficial for disease differentiation and evaluating progression in patients with ALS. Compared with levels in serum, the levels of FHC and FLC in CSF might be more reliable for diagnosing and assessing the progression of ALS. © 2016 John Wiley & Sons A/S.

    2015-02-01

    The reporting of embryo transfer methods in IVF research was assessed through a cross-sectional analysis of randomized controlled trials (RCTs) published between 2010 and 2011. A systematic search identified 325 abstracts; 122 RCTs were included in the study. Embryo transfer methods were described in 42 out of 122 articles (34%). Catheters (32/42 [76%]) or ultrasound guidance (31/42 [74%]) were most frequently mentioned. Performer 'blinding' (12%) or technique standardization (7%) were seldom reported. The description of embryo transfer methods was significantly more common in trials published by journals with lower impact factor (less than 3, 39.6%; 3 or greater, 21.5%; P = 0.037). Embryo transfer methods were reported more often in trials with pregnancy as the main end-point (33% versus 16%) or with positive outcomes (37.8% versus 25.0%), albeit not significantly. Multivariate logistic regression confirmed that RCTs published in higher impact factor journals are less likely to describe embryo transfer methods (OR 0.371; 95% CI 0.143 to 0.964). Registered trials, trials conducted in an academic setting, multi-centric studies or full-length articles were not positively associated with embryo transfer methods reporting rate. Recent reports of randomized IVF trials rarely describe embryo transfer methods. The under-reporting of research methods might compromise reproducibility and suitability for meta-analysis.

  1. Real-time co-registered ultrasound and photoacoustic imaging system based on FPGA and DSP architecture

    NASA Astrophysics Data System (ADS)

    2011-03-01

    Co-registering ultrasound (US) and photoacoustic (PA) imaging is a logical extension to conventional ultrasound because both modalities provide complementary information of tumor morphology, tumor vasculature and hypoxia for cancer detection and characterization. In addition, both modalities are capable of providing real-time images for clinical applications. In this paper, a Field Programmable Gate Array (FPGA) and Digital Signal Processor (DSP) module-based real-time US/PA imaging system is presented. The system provides real-time US/PA data acquisition and image display for up to 5 fps* using the currently implemented DSP board. It can be upgraded to 15 fps, which is the maximum pulse repetition rate of the used laser, by implementing an advanced DSP module. Additionally, the photoacoustic RF data for each frame is saved for further off-line processing. The system frontend consists of eight 16-channel modules made of commercial and customized circuits. Each 16-channel module consists of two commercial 8-channel receiving circuitry boards and one FPGA board from Analog Devices. Each receiving board contains an IC† that combines. 8-channel low-noise amplifiers, variable-gain amplifiers, anti-aliasing filters, and ADC's‡ in a single chip with sampling frequency of 40MHz. The FPGA board captures the LVDSξ Double Data Rate (DDR) digital output of the receiving board and performs data conditioning and subbeamforming. A customized 16-channel transmission circuitry is connected to the two receiving boards for US pulseecho (PE) mode data acquisition. A DSP module uses External Memory Interface (EMIF) to interface with the eight 16-channel modules through a customized adaptor board. The DSP transfers either sub-beamformed data (US pulse-echo mode or PAI imaging mode) or raw data from FPGA boards to its DDR-2 memory through the EMIF link, then it performs additional processing, after that, it transfer the data to the PC** for further image processing. The PC code performs image processing including demodulation, beam envelope detection and scan conversion. Additionally, the PC code pre-calculates the delay coefficients used for transmission focusing and receiving dynamic focusing for different types of transducers to speed up the imaging process. To further speed up the imaging process, a multi-threads technique is implemented in order to allow formation of previous image frame data and acquisition of the next one simultaneously. The system is also capable of doing semi-real-time automated SO2 imaging at 10 seconds per frame by changing the wavelength knob of the laser automatically using a stepper motor controlled by the system. Initial in vivo experiments were performed on animal tumors to map out its vasculature and hypoxia level, which were superimposed on co-registered US images. The real-time system allows capturing co-registered US/PA images free of motion artifacts and also provides dynamitic information when contrast agents are used.

    The addressable inverter matrix consists of 222 inverters each accessible with the aid of a shift register. The structure has proven useful in characterizing the variability of inverter transfer curves and in diagnosing processing faults. For good 3-micron CMOS bulk inverters investigated, the percent standard deviation of the inverter threshold voltage was less than one percent and the inverter gain (the slope of the inverter transfer curve at the inverter threshold vltage) was less than 3 percent. The average noise margin for the inverters was near 2 volts for a power supply voltage of 5 volts. The specific faults studied included undersize pull-down transistor widths and various open contacts in the matrix.

    Multiple simulation training programs have demonstrated that effective transfer of skills can be attained and applied into a more complex scenario, but evidence regarding transfer to the operating room is limited. To assess junior residents trained with simulation performing an advanced laparoscopic procedure in the OR and compare results to those of general surgeons without simulation training and expert laparoscopic surgeons. Experimental study: After a validated 16-session advanced laparoscopy simulation training program, junior trainees were compared to general surgeons (GS) with no simulation training and expert bariatric surgeons (BS) in performing a stapled jejuno-jejunostomy (JJO) in the OR. Global rating scale (GRS) and specific rating scale scores, operative time and the distance traveled by both hands measured with a tracking device, were assessed. In addition, all perioperative and immediate postoperative morbidities were registered. Ten junior trainees, 12 GS and 5 BS experts were assessed performing a JJO in the OR. All trainees completed the entire JJO in the OR without any takeovers by the BS. Six (50 %) BS takeovers took place in the GS group. Trainees had significantly better results in all measured outcomes when compared to GS with considerable higher GRS median [19.5 (18.8-23.5) vs. 12 (9-13.8) p < 0.001] and lower operative time. One morbidity was registered; a patient in the trainees group was readmitted at postoperative day 10 for mechanical ileus that resolved with medical treatment. This study demonstrated transfer of advanced laparoscopic skills acquired through a simulated training program in novice surgical residents to the OR.

    Interhospital transfer is an understudied area within transitions of care. The process by which hospitals accept and transfer patients is not well described. National trends and best practices are unclear. To describe the demographics of large transfer centers, to identify common handoff practices, and to describe challenges and notable innovations involving the interhospital transfer handoff process. A convenience sample of 32 tertiary care centers in the United States was studied. Respondents were typically transfer center directors surveyed by phone. Data regarding transfer center demographics, handoff communication practices, electronic infrastructure, and data sharing were obtained. The median number of patients transferred each month per receiving institution was 700 (range, 250-2500); on average, 28% of these patients were transferred to an intensive care unit. Transfer protocols and practices varied by institution. Transfer center coordinators typically had a medical background (78%), and critical care-trained registered nurse was the most prevalent (38%). Common practices included: mandatory recorded 3-way physician-to-physician conversation (84%) and mandatory clinical status updates prior to patient arrival (81%). However, the timeline of clinical status updates was variable. Less frequent transfer practices included: electronic medical record (EMR) cross-talk availability and utilization (23%), real-time transfer center documentation accessibility in the EMR (32%), and referring center clinical documentation available prior to transport (29%). A number of innovative strategies to address challenges involving interhospital handoffs are reported. Interhospital transfer practices vary widely amongst tertiary care centers. Practices that lead to improved patient handoffs and reduced medical errors need additional prospective evaluation.

    90Sr is considered as a dangerous contaminant of agri-food supply chains due to its chemical affinity with Calcium, which makes its absorption in bones easy. 90Sr accumulation in raw materials and then in final products is particularly significant in relationship to its ability to transfer into animal source products. The radionuclides transfer (137Cs and 90Sr) from environment to forages and then to products of animal origin (milk, cow and pork meats) was studied and evaluated in different studies, which were carried out in contaminated areas, from Chernobyl disaster until today. In the present work, the development and validation of a radiochemical method for the detection of 90Sr in different types of animal feed, and the application of this technique for routinely control activities, are presented. Liquid scintillation counting was the employed analytical technique, since it is able to determine very low activity concentrations of 90Sr (<0.01 Bq Kg–1). All samples analysed showed a 90Sr contamination much higher than method detection limit (0.008 Bq kg–1). In particular, the highest mean activity concentration was registered in hay samples (2.93 Bq kg–1), followed by silage samples (2.07 Bq kg–1) and animal feeds (0.77 Bq kg–1). In fact, all samples were characterized by 90Sr activity concentrations much lower than reference limits. This notwithstanding, the necessity to monitor these levels was confirmed, especially considering that 90Sr is a possible carcinogen for human. PMID:27800378

    This study proposes a steady-state visual evoked potential (SSVEP)-based brain-computer interface (BCI) independent of amplitude-frequency and phase calibrations. Six stepping delay flickering sequences (SDFSs) at 32-Hz flickering frequency were used to implement a six-command BCI system. EEG signals recorded from Oz position were first filtered within 29-35 Hz, segmented based on trigger events of SDFSs to obtain SDFS epochs, and then stored separately in epoch registers. An epoch-average process suppressed the inter-SDFS interference. For each detection point, the latest six SDFS epochs in each epoch register were averaged and the normalized power of averaged responses was calculated. The visual target that induced the maximum normalized power was identified as the visual target. Eight subjects were recruited in this study. All subjects were requested to produce the "563241" command sequence four times. The averaged accuracy, command transfer interval, and information transfer rate (mean ± std.) values for all eight subjects were 97.38 ± 5.97%, 3.56 ± 0.68 s, and 42.46 ± 11.17 bits/min, respectively. The proposed system requires no calibration in either the amplitude-frequency characteristic or the reference phase of SSVEP which may provide an efficient and reliable channel for the neuromuscular disabled to communicate with external environments.

    If a fresh embryo, assisted reproductive technology procedure cycle is unsuccessful and there are frozen embryos available, a frozen-thawed embryo transfer is performed. In some specific cases women may undergo oocyte donation treatment. In both situations the endometrium is primed by the administration of estrogen and progesterone. To prevent the possibility of spontaneous ovulation, gonadotropin-releasing hormone (GnRH) agonists are frequently used. To evaluate the most effective endometrial preparation for women undergoing transfer with frozen embryos or embryos from donor oocytes with regard to the subsequent live birth rate. We searched the Cochrane Menstrual Disorders and Subfertility Group Trials Register, Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library), MEDLINE, EMBASE, LILACS, and abstracts of reproductive societies' meetings (from inception). No language restrictions were applied. Experts in the field were contacted. Randomised controlled trials evaluating endometrial preparation in women undergoing fresh donor cycles and frozen embryo transfers. Two review authors independently applied the inclusion criteria, assessed trial risk of bias, and extracted data. Twenty two randomised controlled trials were included. Five studies analysed the use of a GnRH agonist versus control. No significant benefit was demonstrated when using GnRH agonists. No evidence of statistically significant benefit was found for one GnRH agonist over another, or vaginal over intramuscular progesterone administration. No difference in pregnancy rate was demonstrated when no treatment was compared to aspirin, steroids, ovarian stimulation, or human chorionic gonadotropin (hCG) prior to embryo transfer, although using hCG several times before the oocyte retrieval decreases the pregnancy rate. Finally, when oocyte recipients were studied further, starting progesterone on the day of oocyte pick-up (OPU) or the day after OPU produced a significantly higher pregnancy rate (OR 1.87, 95% CI 1.13 to 3.08) than when recipients started progesterone the day prior to OPU. There is insufficient evidence to recommend any one particular protocol for endometrial preparation over another with regard to pregnancy rates after embryo transfers. These were either frozen embryos or embryos derived from donor oocytes. However, there is evidence of a lower pregnancy rate and a higher cycle cancellation rate when the progesterone supplementation is commenced prior to oocyte retrieval in oocyte donation cycles. Adequately powered studies are needed to evaluate each treatment more accurately.

  14. Australian immunisation registers: established foundations and opportunities for improvement.

    2012-04-19

    The National Immunisation Program Schedule in Australia is formulated and funded nationally under the population-wide Medicare system. The policy is implemented by the eight state and territory jurisdictions. The national immunisation registers consist of the Australian Childhood Immunisation Register (ACIR), and, more recently, the National Human Papillomavirus (HPV) Vaccination Program Register. Moreover, a variety of jurisdiction-based registers and primary care practice software systems exist, which interact with the national registers. General practitioners can obtain reports listing patients under seven years attending their practice and recorded as 'not fully immunised', and immunisation coverage rates for their practice linked to government incentives through Medicare. A 2011 report documents national coverage of 91.8% fully immunised at 12 months, and 92.6% at 24 months. The HPV register provides information on vaccination coverage with the potential to link with a register of cervical cancer screening results. Limitations of current national register include inability to easily access immunisation histories beyond seven years of age, and issues of underreporting and timeliness, which impact significantly the immunisation coverage estimates. The linkage of these registers with healthcare outcome data will further enhance public health outcomes by enabling rapid, population-level vaccine safety and effectiveness investigations in a nation with a track record as an 'early adopter' of new childhood vaccines.

  16. Attitudes of Dental Hygienists towards Independent Practice and Professional Autonomy.

    PubMed

    Catlett, April

    2016-08-01

    The purpose of this cross-sectional, quantitative research was to examine if registered dental hygienists feel competent to work independently based on regulations of dental supervision. A stratified sample of 360 dental hygienists from 8 states completed the Dempster Practice Behaviors Scale survey. ANOVA and MANOVA analyses revealed how state dentist supervision level, age, degree of education, employment status, gender and years of clinical experience affect the perceived autonomy of professional dental hygienists. The response rate included 360 dental hygienists from 8 states. According to the findings age, education level and gender affected the hygienist's level of autonomy. In all 8 states, the registered dental hygienists have a high level of autonomy and feel competent to work independently. The DPBS scores of the sample registered dental hygienists suggest that they feel prepared and competent to perform preventive dental hygiene services without dentist supervision. The attitudes of the dental hygienist sample from each of the 4 state dentist supervision levels supports a move toward achieving professional jurisdiction of preventive dental care within the U.S. Copyright © 2016 The American Dental Hygienists’ Association.

  17. The accuracy of age—sex registers, practice medical records and family practitioner committee registers

    This paper presents the results of a point prevalent evaluation of the comparative reliability and validity of age-sex registers, practice medical records and family practitioner committee (FPC) registers from five teaching practices. They all exhibited similar levels of acceptable accuracy for patient names, sex and age, but the distribution of wrong addresses varied greatly: practice medical records 3·9 per cent, age-sex registers 8·2 per cent and FPC registers 17·1 per cent. The presence of a patient entry in all three registers was associated with a high degree of probability (95·3 per cent) that this individual would be a bona fide practice patient. The register population inflation rates were FPC records 5·5 per cent, practice records 9·8 per cent and age-sex registers 10·6 per cent, but there were large variations between individual practices. A statistically significant contribution to inflation rates came from the age groups 0 to 1 and 21 to 40 (p<0·0005). The register population deflation rates were minimal. The significance of these findings is discussed and the need for practices to determine the accuracy of their individual age-sex registers is stressed. A convenient and economic method for so doing is suggested. We also suggest ways of making it easier to construct and use age-sex registers, since they can be a most versatile and useful aid to research in general practice. ImagesFigure 1. PMID:7320986

    To illustrate the method of cohort reporting of persons with diabetes mellitus (DM) in a primary healthcare clinic in Amman, Jordan, serving Palestine refugees with the aim of improving quality of DM care services. A descriptive study using quarterly and cumulative case findings, as well as cumulative and 12-month analyses of cohort outcomes collected through E-Health in UNRWA Nuzha Primary Health Care Clinic. There were 55 newly registered patients with DM in quarter 1, 2012, and a total of 2851 patients with DM ever registered on E-Health because this was established in 2009. By 31 March 2012, 70% of 2851 patients were alive in care, 18% had failed to present to a healthcare worker in the last 3 months and the remainder had died, transferred out or were lost to follow-up. Cumulative and 12-month cohort outcome analysis indicated deficiencies in several components of clinical care: measurement of blood pressure, annual assessments for foot care and blood tests for glucose, cholesterol and renal function. 10-20% of patients with DM in the different cohorts had serious late complications such as blindness, stroke, cardiovascular disease and amputations. Cohort analysis provides data about incidence and prevalence of DM at the clinic level, clinical management performance and prevalence of serious morbidity. It needs to be more widely applied for the monitoring and management of non-communicable chronic diseases. © 2012 Blackwell Publishing Ltd.

    High levels of work-related stress are associated with increased absenteeism from work and reduced work ability. In this study, we investigated the effects of a stress management intervention on absenteeism and return to work. We randomized 102 participants into either the intervention or wait-list control (WLC) group. The intervention group received the intervention in weeks 1-16 from baseline, and the WLC group received the intervention in weeks 17-32. Self-reported data on absenteeism (number of days full- or part-time absent from work within the previous three months) were obtained at 16, 32, and 48 weeks follow-up. Register-based data on long-term absence from work were drawn from the Danish public transfer payments (DREAM) database from baseline and 48 weeks onwards. The DREAM database contains weekly information on long-term sickness absence compensation. The threshold to enter DREAM is sick leave for two consecutive weeks. At follow-up in week 16, self-reported absenteeism in the intervention group [median 11 days (range 3-25)] was lower (P=0.02) than in the WLC group [median 45 days (range 19-60)], corresponding to a 29% [95% confidence interval (95% CI) 5-52] reduction. On register-based data (cumulated weeks in DREAM, weeks 1-16), the intervention group median [6 weeks (range 0-11)] was lower than that of the WLC group [median 12 weeks (range 8-16)], though not significantly (P=0.06), corresponding to a 21% (95% CI 0-42) reduction. For return to work, a hazard ratio of 1.58 (95% CI 0.89-2.81) favoring the intervention group was found (P=0.12). The intervention reduces self-reported absenteeism from work. A similar trend was found from register-based records. No conclusive evidence was found for return to work.

    Lists of patients receiving repeat prescriptions for epilepsy, diabetes, thyroid disease and asthma were compared with chronic disease registers stored on seven practice computers. Diabetes was the most accurately recorded disease: the names of 72% of patients receiving medication for this condition appeared on the relevant disease registers. Agreement between the two data sources was 68% for thyroid disease, 58% for asthma and 49% for epilepsy. The levels of accuracy are not yet high enough for the computerised chronic disease registers to provide an accurate estimate of the prevalence of these conditions, but new system developments suggest a more optimistic outlook for the future.

    We examine a strategy for improving oral health in the United States by focusing on low-income children in school-based settings. Vulnerable children often experience cultural, social, economic, structural, and geographic barriers when trying to access dental services in traditional dental office settings. These disparities have been discussed for more than a decade in multiple US Department of Health and Human Services publications. One solution is to revise dental practice acts to allow registered dental hygienists increased scope of services, expanded public health delivery opportunities, and decreased dentist supervision. We provide examples of how federally qualified health centers have implemented successful school-based dental models within the parameters of two state policies that allow registered dental hygienists varying levels of dentist supervision. Changes to dental practice acts at the state level allowing registered dental hygienists to practice with limited supervision in community settings, such as schools, may provide vulnerable populations greater access to screening and preventive services. We derive our recommendations from expert opinion. PMID:28661808

    Many modern processors are capable of exploiting data-level parallelism through the use of single instruction multiple data (SIMD) execution. The new Intel Xeon Phi coprocessor supports 512 bit vector registers for the high performance computing. In this paper, we have developed a hierarchical parallelization scheme for accelerated molecular dynamics simulations with the Terfoff potentials for covalent bond solid crystals on Intel Xeon Phi coprocessor systems. The scheme exploits multi-level parallelism computing. We combine thread-level parallelism using a tightly coupled thread-level and task-level parallelism with 512-bit vector register. The simulation results show that the parallel performance of SIMD implementations on Xeon Phi is apparently superior to their x86 CPU architecture.

    This study aims to describe the organization that was implemented at the Rhône-Alpes perinatal hotline, as well as to describe in utero transfer and neonate transport from an epidemiological point of view. A cohort study was performed between January 2003 and December 2004. Every in utero transfer and neonate transport was included. Transfers performed in 2003 were compared to transfers performed in 2004. Three endpoints were defined: the rate of in utero transfer (number of in utero transfers/number of in utero transfers + number of neonatal transfers), the rate of transfer toward level II units (number of transfers from level I to level II/number of transfers from level I to level II + number of transfers from level I to level III) as well as the rate of intra network transfer (number of intra network transfers/number of intra network transfers + number of extra network transfers). In 2003, 865 in utero transfers (IUT) and 1297 neonate transports (NT) were performed, in 2004 848 IUT and 1069 NT were performed. The rate of in utero transfer significantly increased from 40 to 44.2% in 2004 (865/2162 versus 848/1917, p = 0.007). The rate of transfer toward level II units increased for the mothers from 31.8% to 36.9% (177/557 versus 174/471, p = 0.09) and significantly increased for the neonates from 43.2 to 51.6% in 2004 (335/775 versus 327/633, p = 0.002). Finally the rate of intra network transfer has not significantly changed: for the IUT it decreased from 87 to 86% (755/865 versus 732/848, p = 0.59) and for the NT from 91% to 90% (1179/1297 versus 963/1069, p = 0.45). The organization that was implemented allows not only a safe 24 hour on call management of maternal transfers as well as neonate transport, but also a precise knowledge of epidemiologic indications relative to perinatal transfer.

    In general, in vitro fertilisation (IVF) or intracytoplasmic sperm injection (ICSI) implies a single fresh and one or more frozen-thawed embryo transfers. Alternatively, the 'freeze-all' strategy implies transfer of frozen-thawed embryos only, with no fresh embryo transfers. In practice, both strategies can vary technically including differences in freezing techniques and timing of transfer of cryopreservation, that is vitrification versus slow freezing, freezing of two pro-nucleate (2pn) versus cleavage-stage embryos versus blastocysts, and transfer of cleavage-stage embryos versus blastocysts.In the freeze-all strategy, embryo transfers are disengaged from ovarian stimulation in the initial treatment cycle. This could avoid a negative effect of ovarian hyperstimulation on the endometrium and thereby improve embryo implantation. It could also reduce the risk of ovarian hyperstimulation syndrome (OHSS) in the ovarian stimulation cycle by avoiding a pregnancy.We compared the benefits and risks of the two treatment strategies. To evaluate the effectiveness and safety of the freeze-all strategy compared to the conventional IVF/ICSI strategy in women undergoing assisted reproductive technology. We searched the Cochrane Gynaecology and Fertility Group Trials Register, the Cochrane Central Register of Studies (CRSO), MEDLINE, Embase, PsycINFO, CINAHL, and two registers of ongoing trials in November 2016 together with reference checking and contact with study authors and experts in the field to identify additional studies. We included randomised clinical trials comparing a freeze-all strategy with a conventional IVF/ICSI strategy which includes fresh transfer of embryos in women undergoing IVF or ICSI treatment. We used standard methodological procedures recommended by Cochrane. The primary review outcomes were cumulative live birth and OHSS. Secondary outcomes included other adverse effects (miscarriage rate). We included four randomised clinical trials analysing a total of 1892 women comparing a freeze-all strategy with a conventional IVF/ICSI strategy. The evidence was of moderate to low quality due to serious risk of bias and (for some outcomes) serious imprecision. Risk of bias was associated with unclear blinding of investigators for preliminary outcomes of the study, unit of analysis error, and absence of adequate study termination rules.There was no clear evidence of a difference in cumulative live birth rate between the freeze-all strategy and the conventional IVF/ICSI strategy (odds ratio (OR) 1.09, 95% confidence interval (CI) 0.91 to 1.31; 4 trials; 1892 women; I 2 = 0%; moderate-quality evidence). This suggests that if the cumulative live birth rate is 58% following a conventional IVF/ICSI strategy, the rate following a freeze-all strategy would be between 56% and 65%.The prevalence of OHSS was lower after the freeze-all strategy compared to the conventional IVF/ICSI strategy (OR 0.24, 95% CI 0.15 to 0.38; 2 trials; 1633 women; I 2 = 0%; low-quality evidence). This suggests that if the OHSS rate is 7% following a conventional IVF/ICSI strategy, the rate following a freeze-all strategy would be between 1% and 3%.The freeze-all strategy was associated with fewer miscarriages (OR 0.67, 95% CI 0.52 to 0.86; 4 trials; 1892 women; I 2 = 0%; low-quality evidence) and a higher rate of pregnancy complications (OR 1.44, 95% CI 1.08 to 1.92; 2 trials; 1633 women; low-quality evidence). There was no difference in multiple pregnancies per woman after the first transfer (OR 1.11, 95% CI 0.85 to 1.44; 2 trials; 1630 women; low-quality evidence), and no data were reported for time to pregnancy. We found moderate-quality evidence showing that one strategy is not superior to the other in terms of cumulative live birth rates. Time to pregnancy was not reported, but it can be assumed to be shorter using a conventional IVF/ICSI strategy in the case of similar cumulative live birth rates, as embryo transfer is delayed in a freeze-all strategy. Low-quality evidence suggests that not performing a fresh transfer lowers the OHSS risk for women at risk of OHSS.

    There is increasing pressure to address the social determinants of health (SDoH) and health inequities through the implementation of culturally acceptable interventions particularly in Sub-Saharan Africa (SSA) where health outcomes are generally poor. Available evaluation research on cash transfers (CTs) suggests that the programs may influence the wider determinants of health in SSA; yet, there has been no attempt to synthesize the evidence regarding their contribution to tackling the SDoH and health inequalities. To date, nearly all the reviews on CTs' impact on health have predominantly featured evidence from Latin America with limited transferability to the social, cultural, and political environments in SSA. Therefore, the aim of this study is to undertake a systematic review to assess the role of CTs in tackling the wider determinants of health and health inequalities in SSA. A systematic review of published and unpublished literature on CTs' impact on health and health determinants covering the period 2000-2016 will be undertaken. Studies will be considered for inclusion if they present quantitative or qualitative data, including all relevant study designs. The SDoH conceptual framework will be used to guide the data extraction process. EPPI Reviewer software will be used for data management and analysis. Studies included in the review will be analyzed by narrative synthesis and/or meta-analysis as appropriate for the nature of the data retrieved. This review will provide empirical evidence on the impact of CTs on SDoH to inform CT policy, implementation, and research in SSA. The protocol follows the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P). This protocol has been registered with the PROSPERO international prospective register of systematic reviews, reference CRD42015025015 .

    Mortality statistics form a crucial component of national Health Management Information Systems (HMIS). However, there are limitations in the availability and quality of mortality data at national level in Viet Nam. This study assessed the completeness of recorded deaths and the reliability of recorded causes of death (COD) in the A6 death registers in the national routine HMIS in Viet Nam. 1477 identified deaths in 2014 were reviewed in two provinces. A capture-recapture method was applied to assess the completeness of the A6 death registers. 1365 household verbal autopsy (VA) interviews were successfully conducted, and these were reviewed by physicians who assigned multiple and underlying cause of death (UCOD). These UCODs from VA were then compared with the CODs recorded in the A6 death registers, using kappa scores to assess the reliability of the A6 death register diagnoses. The overall completeness of the A6 death registers in the two provinces was 89.3% (95%CI: 87.8-90.8). No COD recorded in the A6 death registers demonstrated good reliability. There is very low reliability in recording of cardiovascular deaths (kappa for stroke = 0.47 and kappa for ischaemic heart diseases = 0.42) and diabetes (kappa = 0.33). The reporting of deaths due to road traffic accidents, HIV and some cancers are at a moderate level of reliability with kappa scores ranging between 0.57-0.69 (p<0.01). VA methods identify more specific COD than the A6 death registers, and also allow identification of multiple CODs. The study results suggest that data completeness in HMIS A6 death registers in the study sample of communes was relatively high (nearly 90%), but triangulation with death records from other sources would improve the completeness of this system. Further, there is an urgent need to enhance the reliability of COD recorded in the A6 death registers, for which VA methods could be effective. Focussed consultation among stakeholders is needed to develop a suitable mechanism and process for integrating VA methods into the national routine HMIS A6 death registers in Viet Nam.

    This study examines if there exists a positive association between socioeconomic status and the proportion of male births in humans, as proposed by Trivers and Willard in 1973, using individual-level data drawn from the complete population of Sweden. We examine more than 3,000,000 births between 1960 and 2007 using administrative register data with comprehensive information on various dimensions of socioeconomic status. We use six different operationalizations of socioeconomic status, including earnings, post-transfer income (including government allowances), wealth, parental wealth, educational level, and occupational class. We apply regression models that compare both changes in status for the same woman over time and differences in status across different women. We also measure socioeconomic status both at the year of child birth and the year of conception. Our results show the absence of any relationship between socioeconomic status and sex ratios, using a large number of different operationalizations of status. We conclude that no substantive relationship between socioeconomic status and sex ratios exists for the population and period of our study. © 2015 Wiley Periodicals, Inc.

  12. The play of transference: some reflections on enactment in the psychoanalytic situation.

    PubMed

    McLaughlin, J T

    1987-01-01

    The incessant play of nonverbal activity between patient and analyst actualizes and amplifies the primary verbal data of the psychoanalytic dialogue. Both parties must inevitably register this kinesic level of communication, and react with capacities acquired in and elaborated from earliest childhood. The analyst's apperceptive (unfocused) looking, as part of his freely hovering attentiveness, utilizes these capabilities gradually to perceive and organize patterns combining the verbal and nonverbal data. It is through the recognizing and eventual understanding of these gestalts that the analyst builds up his knowledge of his patients. In these patterns can be identified: (a) conspicuous behaviors, idiosyncratic for the individual, which often yield to psychoanalytic inquiry to reveal their dynamic-historical antecedents; and (b) inconspicuous background kinesics, habitual to the individual, which ordinarily are opaque to analytic exploration, yet hold rich meaning. Observing these small behaviors in relation to verbal content provides evidence of their linkage to, and enactment of, pregenital- and genital-level conflicts over diadic and triadic object relations, even in highly structured personalities. These enactments combine elements of play, miming, and drama to constitute an experiential dimension that actualizes and externalizes the patients' inner life of conflict and relation to objects.

  13. Does simulation enhance nurses' ability to assess deteriorating patients?

    PubMed

    Recognising and responding to patient deterioration has been identified as a key skill in nursing care to ensure that care is escalated for prompt, efficient management of the potentially critically ill patient. Simulation is one teaching strategy that has been established in nurse education as a method for enhancing skills. The objective was to explore the experiences of registered nurses to ascertain whether they perceived that simulation enhanced their skills in recognising the deteriorating patient. An exploratory qualitative design was used. Data were collected from registered nurses using semi-structured interviews following a professional development course where scenario-based simulation had been used to assess the patient. Eight registered nurses were interviewed for this study. Semi-structured interviews were conducted face to face. Verbatim transcripts were analysed using thematic analysis to identify major themes. Four themes were identified: knowledge, improved assessment skills in caring for the acutely ill patient, the learning environment and decision making. The use of simulation as a strategy was perceived by nurses to improve their own ability in identifying deteriorating patients. The participants described how their knowledge was transferred to clinical practice, with the overall perception that this led to improved patient care. Copyright © 2017 Elsevier Ltd.

    Thematic mapper data for the southern Sierra Nevada area were registered to digital topographic data and compared to LANDSAT MSS and NOAA-7 AVHRR data of snow covered areas in order to determine the errors associated with using coarser resolution and to qualify the information lost when high resolution data are not available. Both the zenith and the azimuth variations in the radiative field are considered in an atmospheric radiative transfer model which deals with a plane parallel structured atmosphere composed of different layers, each assumed to be homogeneous in composition and to have a linear in tau temperature profile. Astronomical parameters for each layer are Earth-Sun distance and solar flux at the top of the atmosphere. Atmospheric parameters include pressure temperature, chemical composition of the air molecules, and the composition and size of the aerosol, water droplets, and ice crystals. Outputs of the model are the monochromatic radiance and irradiance at each level. The use of the model in atmospheric correction of remotely sensed data is discussed.

    Communication skills training has proven to be an effective means to enhance communication of health care professionals in oncology. These effects are well studied in standardized settings. The question of transferring these skills into clinical consultations remains open. We build up on a previous developed training concept consisting of a workshop and coaching. This training achieved a medium effect size in two studies with standardized patients. In the current study, we expanded and manualized the coaching concept, and we will evaluate effects of a varied number of coaching sessions on real clinical consultations. Our aim is to determine how much coaching oncologists need to transfer communication skills into clinical practice. Physicians of two German medical centers will participate in a workshop for communication skills and will be randomized to either a group with one coaching session or a group with four coaching sessions following the workshop. The participation is voluntary and the physicians will receive medical education points. Consultations held by the participating physicians with actual patients who gave their informed consent will be filmed at three time points. These consultations will be evaluated by blinded raters using a checklist based on the training content (primary outcome). Secondary outcomes will be the self-evaluated communication competence by physicians and an evaluation of the consultations by both physicians and patients. We will evaluate our communication training concept on three levels - rater, physician and patient - and concentrate on the transfer of communication skills into real life situations. As we emphasize the external validity in this study design, limitations will be expected due to heterogeneity of data. With this study we aim to gain data on how to improve communication skills training that will result in better patient outcomes. German Clinical Trials Register DRKS00004385 .

    Data on continuous monitoring of stroke risk among different age and ethnic groups are lacking. We aimed to investigate age and ethnic disparities in stroke incidence over time from an inner-city population-based stroke register. Trends in stroke incidence and before-stroke risk factors were investigated with the South London Stroke Register, a population-based register covering a multiethnic population of 357 308 inhabitants. Age-, ethnicity-, and sex-specific incidence rates with 95% confidence intervals were calculated, assuming a Poisson distribution and their trends over time tested by the Cochran-Armitage test. Four thousand two hundred forty-five patients with first-ever stroke were registered between 1995 and 2010. Total stroke incidence reduced by 39.5% during the 16-year period from 247 to 149.5 per 100 000 population (P<0.0001). Similar declines in stroke incidence were observed in men, women, white groups, and those aged>45 years, but not in those aged 15 to 44 years (12.6-10.1; P=0.2034) and black groups (310.1-267.5; P=0.3633). The mean age at stroke decreased significantly from 71.7 to 69.6 years (P=0.0001). The reduction in prevalence of before-stroke risk factors was mostly seen in white patients aged>55 years, whereas an increase in diabetes mellitus was observed in younger black patients aged 15 to 54 years. Total stroke incidence decreased during the 16-year time period. However, this was not seen in younger age groups and black groups. The advances in risk factor reduction observed in white groups aged>55 years failed to be transferred to younger age groups and black groups.

  18. Does administering a comprehensive examination affect pass rates on the Registered Health Information Administrator certification examination?

    2009-01-01

    The purpose of this research study was to determine whether the administration of a comprehensive examination before graduation increases the percentage of students passing the Registered Health Information Administrator certification examination. A t-test for independent means yielded a statistically significant difference between the Registered Health Information Administrator certification examination pass rates of health information administration programs that administer a comprehensive examination and programs that do not administer a comprehensive examination. Programs with a high certification examination pass rate do not require a comprehensive examination when compared with those programs with a lower pass rate. It is concluded that health information administration faculty at the local level should perform program self-analysis to improve student progress toward achievement of learning outcomes and entry-level competencies.

    The voice source differs between modal and falsetto registers, but singers often try to reduce the associated timbral differences, some even doubting that there are any. A total of 54 vowel sounds sung in falsetto and modal register by 13 male more or less experienced choir singers were analyzed by inverse filtering and electroglottography. Closed quotient, maximum flow declination rate, peak-to-peak airflow amplitude, normalized amplitude quotient, and level difference between the two lowest source spectrum partials were determined, and systematic differences were found in all singers, regardless of experience of singing. The observations seem compatible with previous observations of thicker vocal folds in modal register.

    The aim of this study is to investigate whether experience of meaning at work (MAW) and affective organizational commitment (AOC) predict risk of disability pensioning in four occupational groups. Survey data from 40,554 individuals were fitted to a national register (DREAM) containing information on payments of disability pension. Using multi-adjusted Cox-regression, observations were followed in the DREAM-register to assess risk of disability pensioning. Low levels of MAW significantly increased risk of disability pensioning during follow-up referencing high levels of MAW. Respondents with medium levels of AOC had a significantly reduced risk of disability pensioning, when compared to respondents with high levels of AOC. Furthermore, results indicate an interaction effect between AOC and MAW in predicting risk of disability pension. AOC and MAW are significantly associated with risk of disability pensioning. Promoting MAW and managing AOC in contemporary workplaces may contribute towards reducing risk of disability pensioning. © 2014 Wiley Periodicals, Inc.

    Field-programmable gate arrays (FPGAs) can potentially be configured as beamforming platforms for ultrasound imaging, but a long design time and skilled expertise in hardware programming are typically required. In this article, we present a novel approach to the efficient design of FPGA beamformers for synthetic aperture (SA) imaging via the use of software-based high-level synthesis techniques. Software kernels (coded in OpenCL) were first developed to stage-wise handle SA beamforming operations, and their corresponding FPGA logic circuitry was emulated through a high-level synthesis framework. After design space analysis, the fine-tuned OpenCL kernels were compiled into register transfer level descriptions to configure an FPGA as a beamformer module. The processing performance of this beamformer was assessed through a series of offline emulation experiments that sought to derive beamformed images from SA channel-domain raw data (40-MHz sampling rate, 12 bit resolution). With 128 channels, our FPGA-based SA beamformer can achieve 41 frames per second (fps) processing throughput (3.44 × 10(8) pixels per second for frame size of 256 × 256 pixels) at 31.5 W power consumption (1.30 fps/W power efficiency). It utilized 86.9% of the FPGA fabric and operated at a 196.5 MHz clock frequency (after optimization). Based on these findings, we anticipate that FPGA and high-level synthesis can together foster rapid prototyping of real-time ultrasound processor modules at low power consumption budgets.

    Based on national registers, the prevalence of intellectual disability (ID) in Norway is estimated to be 0.44 per 100 inhabitants. This study aimed to examine geographic and urban-rural differences in the prevalence of ID in Norway. Methods A survey based on the national register. Financial transfers intended to provide equal services to people with ID are based on these reports. Results A higher prevalence was found in the North region of Norway. A negative correlation between the population density and the prevalence of ID was also found. Conclusion There was considerable geographic and urban-rural differences in the prevalence of ID, which may be attributable to not only the large diversity of services, but also some other factors. The results were discussed with respect to the deinstitutionalisation progress, resource-intensive services and costs. Differences also reflect some problems in diagnosing ID in people having mild ID.

Qualitative study using focus groups (10) and interviews (13). England and Northern Ireland. 68 people with MS, neurologists, MS nurses, health services management professionals, researchers, representatives from pharmaceutical companies and social care professionals. People with MS expressed open and altruistic views towards the use of their personal information to facilitate service provision and research, placing trust in responsible guardianship and legitimate use of their information. Participant's proposed that people with MS should be able to select their individual level of involvement in a register using levels of consent. It was agreed that access to the register should be governed by a guardianship committee composed of a range of stakeholders. People with MS did not wish their details to be used by marketing agencies and did not consider this a legitimate use of their data. Whilst participants were positive of the role a register could play in promoting research, participants felt that access to data by pharmaceutical industries should be administered by the guardianship committee. People with MS are concerned should their employers be able to access their personal information. Professionals were more cautious than people with MS in their approach to the use of patient personal data within a register. Whilst all stakeholders were positive of the benefits of an MS register, development of such a resource must incorporate robust data security and guardianship measures in order to ensure that, whilst opportunities are maximised, risks to the privacy of individuals and legal challenges to professionals are avoided.

    Accurate registration of International Ultraviolet Explorer (IUE) images is crucial because the variability of the geometrical distortions that are introduced by the SEC-Vidicon cameras ensures that raw science images are never perfectly aligned with the Intensity Transfer Functions (ITFs) (i.e., graded floodlamp exposures that are used to linearize and normalize the camera response). A technique for precisely registering IUE images which uses a cross correlation of the fixed pattern that exists in all raw IUE images is described.

    SUMMARY BACKGROUND The Uganda Prisons Service (UPS) is responsible for the health of approximately 32 500 inmates in 233 prisons. In 2008 a rapid UPS assessment estimated TB prevalence at 654/100 000, three times that of the general population (183/100 000). Although treatment programs exist, little is known about treatment completion in sub-Saharan African prisons. METHODS We conducted a retrospective study of Ugandan prisoners diagnosed with TB from June 2011 to November 2012. We analyzed TB diagnosis, TB-HIV comorbidity and treatment completion from national registers and tracked prison transfers and releases. RESULTS A total of 469 prisoners were diagnosed with TB over the 1.5-year period (incidence 955/100 000 person-years). Of 466 prisoners starting treatment, 48% completed treatment, 43% defaulted, 5% died and 4% were currently on treatment. During treatment, 12% of prisoners remaining in the same prison defaulted, 53% of transfers defaulted and 81% of those released were lost to follow-up. The odds of defaulting were 8.36 times greater among prisoners who were transferred during treatment. CONCLUSIONS TB incidence and treatment default are high among Ugandan prisoners. Strategies to improve treatment completion and prevent multidrug resistance could include avoiding transfer of TB patients, improving communications between prisons to ensure treatment follow-up after transfer and facilitating transfer to community clinics for released prisoners.

    The purpose is to determine the efficiency and efficacy of oocyte cryopreservation by slow freezing versus vitrification, recent data collected from the Italian National Assisted Reproductive Technology Register during the period 2009-2014 will be presented and reviewed. The data on oocyte cryopreservation were also compared with the results obtained with embryo cryopreservation and relative IVF with fresh oocytes. During the period 2009-2014 preservation of oocytes by vitrification had a significantly higher survival rate, implantation, and pregnancy rate than slow freezing; however, there are still large variations in success rates among centers in relation to the number of procedures performed. Vitrification has now become the method of choice for oocyte cryopreservation because of better results than slow freezing, but still requires a more standardized utilization. The transfer of fresh or cryopreserved embryo still shows a statistically significant better performance than transfers with embryos obtained with cryopreserved oocytes. Only in a few centers with much experience in cryopreservation are the results between transfers of frozen embryos or embryos obtained from oocyte cryopreservation comparable.

    Objective To explore the methodologies employed in studies assessing transition of care interventions, with the aim of defining goals for the improvement of future studies. Design Systematic review of comparative studies assessing transition to adult care interventions for young people with chronic conditions. Data sources MEDLINE, EMBASE, ClinicalTrial.gov. Eligibility criteria for selecting studies 2 reviewers screened comparative studies with experimental and quasi-experimental designs, published or registered before July 2015. Eligible studies evaluate transition interventions at least in part after transfer to adult care of young people with chronic conditions with at least one outcome assessed quantitatively. Results 39 studies were reviewed, 26/39 (67%) published their final results and 13/39 (33%) were in progress. In 9 studies (9/39, 23%) comparisons were made between preintervention and postintervention in a single group. Randomised control groups were used in 9/39 (23%) studies. 2 (2/39, 5%) reported blinding strategies. Use of validated questionnaires was reported in 28% (11/39) of studies. In terms of reporting in published studies 15/26 (58%) did not report age at transfer, and 6/26 (23%) did not report the time of collection of each outcome. Conclusions Few evaluative studies exist and their level of methodological quality is variable. The complexity of interventions, multiplicity of outcomes, difficulty of blinding and the small groups of patients have consequences on concluding on the effectiveness of interventions. The evaluation of the transition interventions requires an appropriate and common methodology which will provide access to a better level of evidence. We identified areas for improvement in terms of randomisation, recruitment and external validity, blinding, measurement validity, standardised assessment and reporting. Improvements will increase our capacity to determine effective interventions for transition care. PMID:28131998

    The traditional reliance on the transfer of multiple embryos during in vitro fertilisation (IVF) in order to maximise the chance of pregnancy, has resulted in increasing rates of multiple pregnancies. Women undergoing IVF had a 20 - fold increased risk of twins and 400 - fold increased risk of higher order pregnancies (Martin 1998). The maternal and perinatal morbidity and mortality as well as national health service costs associated with multiple pregnancies is significantly high in comparison with singleton births (Luke 1992; Callahan 1994; Goldfarb 1996). Single embryo transfer is now being considered as an effective means of reducing this iatrogenic complication. This systematic review evaluates the effectiveness of elective two embryo transfer in comparison with single and more than two embryo transfer following IVF and ICSI (intra cytoplasmic sperm injection) treatment. The aim of this review is to determine, whether in couples who undergo IVF/ICSI: (1) the elective transfer of two embryos improves the probability of livebirth compared with: (a) Single embryo transfer, (b) Three embryo transfer or (c) Four embryo transfer.(2) the elective transfer of three embryos improves the probability of livebirth compared with: (a) Single embryo transfer, or (b) Four embryo transfer, We searched the Cochrane Menstrual Disorders and Subfertility Group's trials register (searched June 2003), the Cochrane Central Register of Controlled Trials (The Cochrane Library, Issue 4, 2003), MEDLINE (1970 to 2003), EMBASE (1985 to 2003) and reference lists of articles. We also handsearched relevant conference proceedings and contacted researchers in the field. Only randomised controlled trials were included. Two reviewers independently assessed eligibility and quality of trials. We found no studies that compared a policy of transferring multiple embryos on one cycle versus a policy of cryo- preservation and transfer of a single embryo over multiple cycles. We also found no trials comparing transfer of two versus three embryos. Three small, poorly reported trials compared transfer of two versus one embryo in a single cycle, and one small, poorly reported trial compared transfer of two versus four embryos in a single cycle. The clinical pregnancy rate per woman/couple associated with two embryo transfer was significantly higher compared to single embryo transfer (OR 2.08, 95% CI 1.24 to 3.50; test for overall effect p = 0.006). The live birth rate per woman/couple associated with two embryo transfer was also significantly higher than that associated with single embryo transfer (OR 1.90, 95% CI 1.12 to 3.22, test for overall effect p=0.02). The multiple pregnancy rate was significantly lower in women who had single embryo transfer (OR 9.97, 95% CI 2.61 to 38.19; p = 0.0008). The effectiveness of double embryo transfer versus four embryo transfer was tested in a single trial. There was no statistically significant differences in the clinical pregnancy rate (OR 0.75, 95% CI 0.26 to 2.16; p=0.6), and multiple pregnancy rates (OR 0.44. 95% CI 0.10 to 1.97; p = 0.28) between the two groups. The livebirth rate in the four embryo transfer group was higher compared to the two embryo transfer group, but the results were not statistically significant (OR 0.35, 95% CI 0.11 to 1.05; p = 0.06). The results of this systematic review suggest that live birth and pregnancy rates following single embryo transfer are lower than those following double embryo transfer as are the chances of multiple pregnancy including twins. As such, it is unlikely that the conclusions are robust enough to catalyse a change in clinical practice. The studies included are limited by their small sample size, so that even large differences might be hidden. Cumulative livebirth rates are seldom reported. The data were inadequate to draw conclusions about single embryo transfer and first frozen single embryo transfer (1FZET) or subsequent single frozen embryo transfers. Until more evidence is available single embryo transfer may not be the preferred choice for all patients undergoing IVF/ICSI. Clinicians may need to individualise protocols for couples based on their risks of multiple pregnancy. A definitive pragmatic, large multi centre randomised controlled trial comparing single embryo versus double embryo transfer in terms of clinical and cost effectiveness as well as acceptability is required. The primary outcome measured should be cumulative livebirth per woman/couple.

  11. A Wide Dynamic Range Tapped Linear Array Image Sensor

    1988-08-01

    Detectors for acousto-optic signal processing applications require fast transient response as well as wide dynamic range. There are two major choices of detectors: conductive or integration mode. Conductive mode detectors have an initial transient period before they reach then' i equilibrium state. The duration of 1 his period is dependent on light level as well as detector capacitance. At low light levels a conductive mode detector is very slow; response time is typically on the order of milliseconds. Generally. to obtain fast transient response an integrating mode detector is preferred. With integrating mode detectors. the dynamic range is determined by the charge storage capability of the tran-sport shift registers and the noise level of the image sensor. The conventional net hod used to improve dynamic range is to increase the shift register charge storage capability. To achieve a dynamic range of fifty thousand assuming two hundred noise equivalent electrons, a charge storage capability of ten million electrons would be required. In order to accommodate this amount of charge. unrealistic shift registers widths would be required. Therefore, with an integrating mode detector it is difficult to achieve a dynamic range of over four orders of magnitude of input light intensity. Another alternative is to solve the problem at the photodetector aml not the shift, register. DALSA's wide dynamic range detector utilizes an optimized, ion implant doped, profiled MOSFET photodetector specifically designed for wide dynamic range. When this new detector operates at high speed and at low light levels the photons are collected and stored in an integrating fashion. However. at bright light levels where transient periods are short, the detector switches into a conductive mode. The light intensity is logarithmically compressed into small charge packets, easily carried by the CCD shift register. As a result of the logarithmic conversion, dynamic ranges of over six orders of magnitide are obtained. To achieve the short integration times necessary in acousto-optic applications. t he wide dynamic range detector has been implemented into a tapped array architecture with eight outputs and 256 photoelements.

    A survey of female commercial sex workers (CSW) in Iloilo City, Philipines, was conducted in October and November 1995 to determine the level of knowledge, attitudes, and preventive practices regarding HIV/AIDS to guide future education programs. CSWs in the Philippines were categorized as registered or freelance. Registered CSWs included "hospitality girls" from licensed bars, night clubs, and massage parlors who have registered with the local social hygiene clinic (SHC). Freelance CSWs are not registered. 110 registered and 46 freelance CSWs were surveyed. We compared demographic data, scores from a basic knowledge test, and preventive practices between registered and freelance CSWs. Demographic data indicate that registered CSWs often originate from provinces outside of the Visayan Islands (25%) and most have never been married (93%). Freelance CSWs included more married (11%) and separated (11%) women from nearby cities. Knowledge test scores of registered and freelance CSWs were not significantly different. 90-96% of CSWs correctly answered questions regarding modes of transmission. However, 25% still believed it is possible to contract AIDS from using a public restroom. Registered and freelance CSWs believed their risks for AIDS to be equally great. However, 38% of freelance CSWs admit to never or almost never using condoms compared to 15% of registered CSWs. Licensed establishments and a support staff at the social hygiene clinic may provide a relatively structured working environment, giving registered CSWs security and confidence to insist on condom use. In most cases, condom use seems to depend on male customer compliance, and CSWs, especially freelancers, cannot afford to insist on condom use. The CSWs indicated that they learned most about AIDS through health personnel and television.

  13. An Exploratory Descriptive Study of Registered Nurse Innovation: Implications for Levels of Adoption.

    PubMed

    Polster, Debra; Villines, Dana

    The aims of this study were to describe registered nurses' levels of personal innovativeness and registered nurses' perceived organizational innovativeness and determine the relationship between these 2 variables. There is limited research to describe the levels of innovation of nurses within a hospital. The levels of innovation can determine the likelihood of adoption of evidence-based practices at the bedside. As change agents, clinical nurse specialists can determine successful implementation strategies tailored to nurse levels of innovation. This was a descriptive study at a midwest, urban, teaching, 408-bed Magnet hospital. Surveys were completed by 217 nurses. The participants reported high personal innovativeness ((Equation is included in full-text article.)= 32.1; SD, 6.4), and the institution was perceived as innovative, with 90.3% of scores categorized as positive innovativeness. The statistically significant correlation was in the medical-surgical unit (r = -0.52, P < .01). There is no correlation between personal innovativeness and organizational innovativeness except for medical-surgical nurses (P = .03). They are likely to perceive the organization more innovative than themselves. Determining adopter characteristics can be valuable to the clinical nurse specialist by adapting strategic interventions to advance nursing practice. Exploring levels of adoption can be an innovative strategy to transform nursing at the bedside and throughout the organization.

    The possibility of the transfer of a holographic structure that was originally registered on layers of dichromated gelatin (DCG) onto a substrate material of polymethylmethacrylate (PMMA) has been shown. The use of a selective destructive effect of short-wave UV radiation with a wavelength that is less than 270 nm is the basis of the mechanism of formation of secondary relief-phase holographic structure on the surface of PMMA. The optimization of processing modes and selection of developing compositions which are based on isopropanol and methylisobutylketone (MIBK) have been carried out, which made it possible to create reliefphase holographic gratings with high diffraction efficiency (DE) of about 25% and the maximum depth of the surface relief of the order of 1 μm on the substrates of PMMA.

  20. Architectural-level power estimation and experimentation

    NASA Astrophysics Data System (ADS)

    Ye, Wu

    With the emergence of a plethora of embedded and portable applications and ever increasing integration levels, power dissipation of integrated circuits has moved to the forefront as a design constraint. Recent years have also seen a significant trend towards designs starting at the architectural (or RT) level. Those demand accurate yet fast RT level power estimation methodologies and tools. This thesis addresses issues and experiments associate with architectural level power estimation. An execution driven, cycle-accurate RT level power simulator, SimplePower, was developed using transition-sensitive energy models. It is based on the architecture of a five-stage pipelined RISC datapath for both 0.35mum and 0.8mum technology and can execute the integer subset of the instruction set of SimpleScalar . SimplePower measures the energy consumed in the datapath, memory and on-chip buses. During the development of SimplePower , a partitioning power modeling technique was proposed to model the energy consumed in complex functional units. The accuracy of this technique was validated with HSPICE simulation results for a register file and a shifter. A novel, selectively gated pipeline register optimization technique was proposed to reduce the datapath energy consumption. It uses the decoded control signals to selectively gate the data fields of the pipeline registers. Simulation results show that this technique can reduce the datapath energy consumption by 18--36% for a set of benchmarks. A low-level back-end compiler optimization, register relabeling, was applied to reduce the on-chip instruction cache data bus switch activities. Its impact was evaluated by SimplePower. Results show that it can reduce the energy consumed in the instruction data buses by 3.55--16.90%. A quantitative evaluation was conducted for the impact of six state-of-art high-level compilation techniques on both datapath and memory energy consumption. The experimental results provide a valuable insight for designers to develop future power-aware compilation frameworks for embedded systems.

  1. Utility of local health registers in measuring perinatal mortality: A case study in rural Indonesia

    PubMed Central

    2011-01-01

    Background Perinatal mortality is an important indicator of obstetric and newborn care services. Although the vast majority of global perinatal mortality is estimated to occur in developing countries, there is a critical paucity of reliable data at the local level to inform health policy, plan health care services, and monitor their impact. This paper explores the utility of information from village health registers to measure perinatal mortality at the sub district level in a rural area of Indonesia. Methods A retrospective pregnancy cohort for 2007 was constructed by triangulating data from antenatal care, birth, and newborn care registers in a sample of villages in three rural sub districts in Central Java, Indonesia. For each pregnancy, birth outcome and first week survival were traced and recorded from the different registers, as available. Additional local death records were consulted to verify perinatal mortality, or identify deaths not recorded in the health registers. Analyses were performed to assess data quality from registers, and measure perinatal mortality rates. Qualitative research was conducted to explore knowledge and practices of village midwives in register maintenance and reporting of perinatal mortality. Results Field activities were conducted in 23 villages, covering a total of 1759 deliveries that occurred in 2007. Perinatal mortality outcomes were 23 stillbirths and 15 early neonatal deaths, resulting in a perinatal mortality rate of 21.6 per 1000 live births in 2007. Stillbirth rates for the study population were about four times the rates reported in the routine Maternal and Child Health program information system. Inadequate awareness and supervision, and alternate workload were cited by local midwives as factors resulting in inconsistent data reporting. Conclusions Local maternal and child health registers are a useful source of information on perinatal mortality in rural Indonesia. Suitable training, supervision, and quality control, in conjunction with computerisation to strengthen register maintenance can provide routine local area measures of perinatal mortality for health policy, and monitoring of newborn care interventions. Similar efforts are required to strengthen routine health data in all developing countries, to guide planned progress towards reduction in the local, national and international burden from perinatal mortality.

    Phenolic compounds are responsible of the nutritional and sensory quality of extra-virgin olive oil (EVOO). The composition of phenolic compounds in EVOO is related to the initial content of phenolic compounds in the olive-fruit tissues and the activity of enzymes acting on these compounds during the industrial process to produce the oil. In this work, the phenolic composition was studied in six major cultivars grown in the same orchard under the same agronomical and environmental conditions in an effort to test the effects of cultivars on phenolic composition in fruits and oils as well as on transfer between matrices. The phenolic fractions were identified and quantified using high-performance liquid chromatography-diode array detector-time-of-flight-mass spectrometry. A total of 33 phenolic compounds were determined in the fruit samples and a total of 20 compounds in their corresponding oils. Qualitative and quantitative differences in phenolic composition were found among cultivars in both matrices, as well as regarding the transfer rate of phenolic compounds from fruits to oil. The results also varied according to the different phenolic groups evaluated, with secoiridoids registering the highest transfer rates from fruits to oils. Moreover, wide-ranging differences have been noticed between cultivars for the transfer rates of secoiridoids (4.36%-65.63% of total transfer rate) and for flavonoids (0.18%-0.67% of total transfer rate). 'Picual' was the cultivar that transferred secoiridoids to oil at the highest rate, whereas 'Changlot Real' was the cultivar that transferred flavonoids at the highest rates instead. Principal-component analysis confirmed a strong genetic effect on the basis of the phenolic profile both in the olive fruits and in the oils.

    To define the appropriate number of embryos to be transferred at day 5. Retrospective analysis of 784 consecutive fresh day-5 embryo transfers performed between 2007 and 2015, divided in three groups: Group A (N = 219): received the only 2 embryos that reached a transferable stage; Group B (N = 357): received 2 selected embryos among several that reached a transferable stage; Group C (N = 208): received the only 3 developing embryos. Clinical pregnancy, implantation, multiple pregnancy and delivery rates were registered. Kruskal-Wallis and Fisher Exact tests were applied as appropriate. Age and previous attempts were comparable in the 3 groups. Compared with Group A, Groups B and C had a higher oocyte recovery (10.7 ± 5.6 vs. 14.7 ± 8.0 vs. 13.8 ± 6.6), fertilization rate (75.97% vs. 81.60% vs. 83.29%) and percentage of embryos reaching a transferable stage on day 5 (39.98% vs. 63.99% vs. 60.97%), as well as a significantly higher clinical pregnancy (42.92% vs. 61.06% vs. 58.17%) and implantation rates (21.09% vs. 40.98% vs. 36.97%). The multiple pregnancy rate was higher in Groups B and C than in Group A (11.70% vs. 31.19% vs. 37.19%). The high order multiple pregnancy rate (> 2) was significantly increased in group C (1.06% vs. 0.92% vs. 14.05%). In patients with 3 or more day 5 developing embryos, delivery rates are similar if 2 or 3 embryos are transferred. The transfer of 3 embryos carries an unacceptable increase in the risk of high order multiple pregnancy, with its known consequences. According to our data, we should not exceed the number of 2 day-5 fresh embryos transferred.

    Background Mortality statistics form a crucial component of national Health Management Information Systems (HMIS). However, there are limitations in the availability and quality of mortality data at national level in Viet Nam. This study assessed the completeness of recorded deaths and the reliability of recorded causes of death (COD) in the A6 death registers in the national routine HMIS in Viet Nam. Methodology and findings 1477 identified deaths in 2014 were reviewed in two provinces. A capture-recapture method was applied to assess the completeness of the A6 death registers. 1365 household verbal autopsy (VA) interviews were successfully conducted, and these were reviewed by physicians who assigned multiple and underlying cause of death (UCOD). These UCODs from VA were then compared with the CODs recorded in the A6 death registers, using kappa scores to assess the reliability of the A6 death register diagnoses. The overall completeness of the A6 death registers in the two provinces was 89.3% (95%CI: 87.8–90.8). No COD recorded in the A6 death registers demonstrated good reliability. There is very low reliability in recording of cardiovascular deaths (kappa for stroke = 0.47 and kappa for ischaemic heart diseases = 0.42) and diabetes (kappa = 0.33). The reporting of deaths due to road traffic accidents, HIV and some cancers are at a moderate level of reliability with kappa scores ranging between 0.57–0.69 (p<0.01). VA methods identify more specific COD than the A6 death registers, and also allow identification of multiple CODs. Conclusions The study results suggest that data completeness in HMIS A6 death registers in the study sample of communes was relatively high (nearly 90%), but triangulation with death records from other sources would improve the completeness of this system. Further, there is an urgent need to enhance the reliability of COD recorded in the A6 death registers, for which VA methods could be effective. Focussed consultation among stakeholders is needed to develop a suitable mechanism and process for integrating VA methods into the national routine HMIS A6 death registers in Viet Nam. PMID:29370191

    Socioeconomic position and education are strongly associated with several chronic diseases, but their relation to coeliac disease is unclear. We examined educational level and socioeconomic position in patients with coeliac disease. We identified 29,096 patients with coeliac disease through biopsy reports (defined as Marsh 3: villous atrophy) from all Swedish pathology departments (n=28). Age- and sex-matched controls were randomly sampled from the Swedish Total Population Register (n=145,090). Data on level of education and socioeconomic position were obtained from the Swedish Education Register and the Occupational Register. We calculated odds ratios for the risk of having coeliac disease based on socioeconomic position according to the European Socioeconomic Classification (9 levels) and education. Compared to individuals with high socioeconomic position (level 1 of 9) coeliac disease was less common in the lowest socioeconomic stratum (routine occupations=level 9 of 9: adjusted odds ratio=0.89; 95% confidence interval=0.84-0.94) but not less common in individuals with moderately low socioeconomic position: (level 7/9: adjusted odds ratio=0.96; 95% confidence interval=0.91-1.02; and level 8/9: adjusted odds ratio=0.99; 95% confidence interval=0.93-1.05). Coeliac disease was not associated with educational level. In conclusion, diagnosed coeliac disease was slightly less common in individuals with low socioeconomic position but not associated with educational level. Coeliac disease may be unrecognised in individuals of low socioeconomic position. Copyright © 2012 Editrice Gastroenterologica Italiana S.r.l. Published by Elsevier Ltd. All rights reserved.

    Organizational changes have occurred in municipal elderly care in Sweden during the past decades. The 'Adel' reform transferred responsibility for the care of older persons from the county councils to the municipalities. Furthermore, the specialisation in dementia care divided elderly care into two groups: dementia and general care. This change has had a significant impact on the work situation of registered nurses (RNs). The main focus was to describe RNs' work situation and their characteristics in municipal elderly care. Another aim was to compare RNs working solely in dementia care with those working in general care of older persons with diverse diagnoses. A non-experimental, descriptive design with a survey research approach was used. Sixty special housing units with underlying units including those offering daytime activities in a large city in the middle of Sweden. The number of participating RNs was a total of 213, with a response rate of 62.3%. Of the 213 RNs, 95 (44.6%) worked in dementia care, and 118 (55.4%) in general care. A questionnaire survey. The results indicated high levels of time pressure in both groups. Greater knowledge and greater emotional and conflicting demands were found in dementia care. The majority perceived a greater opportunity to plan and perform daily work tasks than to influence the work situation in a wider context. Support at work was perceived as generally high from management and fellow workers and higher in dementia care. It is important to decrease RNs' time pressure and increase their influence on decisions made at work.

    2016-08-11

    To evaluate the relationship between work engagement and psychological capital (PsyCap) levels reported by registered nurses. PsyCap is a developable human resource. Research on PsyCap as an antecedent to work engagement in nurses is needed. A convenience sample of 137 registered nurses participated in this quantitative cross-sectional survey. Questionnaires measured self-reported levels of work engagement and psychological capital. Descriptive and inferential statistics were used for data analysis. There was a statistically significant correlation between work engagement and PsyCap scores (r=0.633, p<0.01). Nurses working at band 5 level reported statistically significantly lower PsyCap scores compared with nurses working at band 6 and 7 levels. Nurses reporting high levels of work engagement also reported high levels of PsyCap. Band 5 nurses might benefit most from interventions to increase their PsyCap. This study supports PsyCap as an antecedent to work engagement.

    To explore key motivational factors of Jordanian nurses to undertake a Master's degree and explore perceived impact on practice. In Jordan, there are postgraduate educational programmes offering a Master's degree in clinical nursing for registered nurses. These programmes are intended to prepare nurses to practise at an advanced level as potential clinical nurse specialists. Little is known about the motivation of nurses to undertake such Master's degree preparation programmes and their perceived impact on practice. Using an ethnographic design, narratives from semi-structured interviews with participants (n=37) from five Jordanian hospitals and two public universities were collected and thematically analysed. Four main themes emerged from the data: self development; broadening career opportunities; developing practice; and the perceived impact of Master's level nurses on practice. The majority of Jordanian nurses chose to undertake a Master's degree because of a desire for self and practice development. The majority of participants referred to M-level nurses in terms of knowledge transfer, highlighting their clinical teaching and in-service education activities. M-level nurses were also associated with managerial and supervisory roles in clinical practice. Controversy over the impact of M-level nurses in enhancing patient care is not limited to the Jordanian setting. Future research needs to focus on comparative studies between nurses with M-level qualifications and experienced nurses without either M-level qualifications or specialist courses to establish if there is any significant relationship between practice performance and educational preparation and experience. Evaluation research could be undertaken for the purpose of developing measurable and observable criteria related to educational and skill based outcomes. Copyright © 2012 Elsevier Ltd.

    Setting: Children aged <15 years constitute 7% of all people living with the human immunodeficiency virus (HIV) in India. A previous study from an antiretroviral therapy (ART) centre in south India reported 82% loss to follow-up (LTFU) among children in pre-ART care (2006–2011). Objective: To assess the proportion of LTFU within 1 year of registration among HIV-infected children (aged < 15 years) registered in all 43 ART centres in the state of Tamil Nadu, India, during the year 2012. Design: This was a retrospective cohort study involving a review of programme records. Results: Of 656 children registered for HIV care, 20 (3%) were not assessed for ART eligibility. Of those remaining, 226 (36%) were not ART eligible and entered pre-ART care. Among these, at 1 year of registration, 50 (22%) were LTFU, 40 (18%) were transferred out and 136 (60%) were retained in care at the same centre. The child's age, sex, World Health Organization stage or occurrence of opportunistic infection were not associated with LTFU. Conclusion: One in five children registered under pre-ART care were lost to follow-up. Stronger measures to prevent LTFU and reinforce retrieval actions are necessary in the existing National HIV Programme. PMID:28695080

    2014-01-01

    The Nun protein of coliphage HK022 arrests RNA polymerase (RNAP) in vivo and in vitro at pause sites distal to phage λ N-Utilization (nut) site RNA sequences. We tested the activity of Nun on ternary elongation complexes (TECs) assembled with templates lacking the λ nut sequence. We report that Nun stabilizes both translocation states of RNAP by restricting lateral movement of TEC along the DNA register. When Nun stabilized TEC in a pretranslocated register, immediately after NMP incorporation, it prevented binding of the next NTP and stimulated pyrophosphorolysis of the nascent transcript. In contrast, stabilization of TEC by Nun in a posttranslocated register allowed NTP binding and nucleotidyl transfer but inhibited pyrophosphorolysis and the next round of forward translocation. Nun binding to and action on the TEC requires a 9-bp RNA–DNA hybrid. We observed a Nun-dependent toe print upstream to the TEC. In addition, mutations in the RNAP β′ subunit near the upstream end of the transcription bubble suppress Nun binding and arrest. These results suggest that Nun interacts with RNAP near the 5′ edge of the RNA–DNA hybrid. By stabilizing translocation states through restriction of TEC lateral mobility, Nun represents a novel class of transcription arrest factors. PMID:24853501

    In Botswana nurses provide most health care in the primary, secondary and tertiary level clinics and hospitals. Trauma and medical emergencies are on the increase, and nurses should have cardiopulmonary resuscitation (CPR) knowledge and skills in order to be able to implement effective interventions in cardiac arrest situations. The objective of this descriptive study was to assess registered nurses’ CPR knowledge and skills. A pre-test, intervention and re-test time-series research design was adopted, and data were collected from 102 nurses from the 2 referral hospitals in Botswana. A multiple-choice questionnaire and checklist were used to collect data. All nurses failed the pre-test. Their knowledge and skills improved after training, but deteriorated over the three months until the post-test was conducted. The significantly low levels of registered nurses’ CPR skills in Botswana should be addressed by instituting country-wide CPR training and regular refresher courses

    The growth of the Gyr breed in Brazil in terms of genetic gain for milk, along with conditions for market, has led to the use of ovum pick-up in vitro production (OPU-IVP) as a leader in biotechnology for the multiplication of genetic material. The aim of this study was to investigate phenotypic correlations between OPU-IVP-linked characteristics and pregnancy rates registered in an embryo transfer program using Gyr cows as oocyte donors. Data collected from 211 OPU sessions and 298 embryo transfers during the years 2012 and 2013 were analyzed and statistical analysis was performed. Estimates of simple Pearson correlations were calculated for NVcoc and PVcoc (number and proportion of viable cumulus-oocyte complexes, respectively); NcleavD4 and PcleavD4 (number and proportion of cleaved embryos on day 4 of culture, respectively); NTembD7 and PTembD7 (number and proportion of transferable embryos on day 7 of culture, respectively); NPrD30 and PPrD30 (number and proportion of pregnancies 30 days after transfer, respectively); and NPrD60 and PPrD60 (number and proportion of pregnancies 60 days after transfer, respectively). Moderate to moderately high correlations were found for all numerical characteristics, suggesting these as the most suitable parameters for selection of oocyte donors in Gyr programs. NVcoc is proposed as a selection trait due to positive correlations with percentage traits and pregnancy rates 30 and 60 days after transfer.

    ART has helped millions of infertile couples worldwide to overcome their childlessness. These successes have been accompanied by an increase in multiple deliveries, and perinatal complications associated. The explanation for this complication is the transfer of more than one embryo, to increase the odds of delivery. Our objective was to compare the outcome of elective dual embryo transfer (eDET) to that of the transfer of more than two embryos without embryo cryopreservation (TET), terms of delivery rate and multiple delivery. We analyzed the data registered by 155 clinics members of the RLA: 11,024 eDET and 10,634 TET. The delivery rate was significantly higher when eDET was performed than when TET was performed (40.24% and 26.98%, p < 0.001). Also, the ratio of twin deliveries was higher in eDET (25.80% and 20.56%, p < 0.001). However, the ratio of triplets and more deliveries was higher in TET than in eDET (2.34%and 0.52%, p < 0.001). These findings were consistent across the different age categories of the female partner. Our findings suggest that eDET was associated with a statistically significant better delivery rate per embryo transfer, and lower ratio of triplet-and-higher deliveries, regardless of the woman's age. Therefore, there is no evidence that supports the transfer of more than two embryos.

    The objective of this study is to estimate the vehicle kilometer traveled (VKT) and on-road emissions using the traffic volume in urban. We estimated two VKT; one is based on registered vehicles and the other is based on traffic volumes. VKT for registered vehicles was 2.11 times greater than that of the applied traffic volumes because each VKT estimation method is different. Therefore, we had to define the inner VKT is moved VKT inner in urban to compare two values. Also, we focused on freight modes because these are discharged much air pollutant emissions. From analysis results, we found middle and large trucks registered in other regions traveled to target city in order to carry freight, target city has included many industrial and logistics areas. Freight is transferred through the harbors, large logistics centers, or via locations before being moved to the final destination. During this process, most freight is moved by middle and large trucks, and trailers rather than small trucks for freight import and export. Therefore, these trucks from other areas are inflow more than registered vehicles. Most emissions from diesel trucks had been overestimated in comparison to VKT from applied traffic volumes in target city. From these findings, VKT is essential based on traffic volume and travel speed on road links in order to estimate accurately the emissions of diesel trucks in target city. Our findings support the estimation of the effect of on-road emissions on urban air quality in Korea. Copyright © 2016. Published by Elsevier B.V.

  7. The influence of regional geological settings on the seismic hazard level in copper mines in the Legnica-Głogów Copper Belt Area (Poland)

    2017-11-01

    The current level of rockburst hazard in copper mines of the (LGOM) Legnica- Głogów Copper Belt Area is mostly the consequence of mining-induced seismicity, whilst the majority of rockbursting events registered to date were caused by high-energy tremors. The analysis of seismic readings in recent years reveals that the highest seismic activity among the copper mines in the LGOM is registered in the mine Rudna. This study investigates the seismic activity in the rock strata in the Rudna mine fields over the years 2006-2015. Of particular interest are the key seismicity parameters: the number of registered seismic events, the total energy emissions, the energy index. It appears that varied seismic activity in the area may be the function of several variables: effective mining thickness, the thickness of burst-prone strata and tectonic intensity. The results support and corroborate the view that principal factors influencing the actual seismic hazard level are regional geological conditions in the copper mines within the Legnica-Głogów Copper Belt Area.

    The aim of this study is to investigate the heat transfer and flow characteristic of cryogenic methane in regenerative cooling system at supercritical pressures. The thermo-physical properties of supercritical methane were obtained from the National institute of Standards and Technology (NIST) webbook. The numerical model was developed based on the assumptions of steady, turbulent and Newtonian flow. For mesh independence test and model validation, the simulation results were compared with published experimental results. The effect of four different performance parameter ranges namely inlet pressure (5 to 8 MPa), inlet temperature (120 to 150 K), heat flux (2 to 5 MW/m2) and mass flux (7000 to 15000 kg/m2s) on heat transfer and flow performances were investigated. It was found that the simulation results showed good agreement with experimental data with maximum deviation of 10 % which indicates the validity of the developed model. At low inlet temperature, the change of specific heat capacity at near-wall region along the tube length was not significant while the pressure drop registered was high. However, significant variation was observed for the case of higher inlet temperature. It was also observed that the heat transfer performance and pressure drop penalty increased when the mass flux was increased. Regarding the effect of inlet pressure, the heat transfer performance and pressure drop results decreased when the inlet pressure is increased.

    To describe registered nurses' reported use of research in the care of older people and to examine associations between research use and factors related to the elements: the communication channels, the adopter and the social system. Research use among registered nurses working in hospital settings has been reported in many studies. Few studies, however, have explored the use of research among registered nurses working in the care of older people. A cross-sectional survey. In eight municipalities, all registered nurses (n = 210) working in older people care were invited to participate (response rate 67%). The Research Utilisation Questionnaire was adopted. Questions concerning the work organisation and research-related resources were sent to the Community Chief Nurse at each municipality. Descriptive statistics and logistic regression were applied. The registered nurses reported a relatively low use of research findings in daily practice, despite reporting a positive attitude to research. The registered nurses reported lack of access to research reports at the work place and that they had little support from unit managers and colleagues. Registered nurses working in municipalities with access to research-related resources reported more use of research than registered nurses without resources. The factors 'Access to research findings at work place', 'Positive attitudes to research' and 'Nursing programme at university level' were significantly associated with research use. There is a great potential to increase registered nurses' use of research findings in the care of older people. Factors which were linked to the communication channels and the adopter were associated with research use. Strategies to enhance research use should focus on access to and adequate training in using information sources, increased knowledge on research methodology and nursing science and a supportive organisation.

    The malleable architecture generator (MARGE) is a tool set that translates high-level parallel C to configuration bit streams for field-programmable logic based computing systems. MARGE creates an application-specific instruction set and generates the custom hardware components required to perform exactly those computations specified by the C program. In contrast to traditional fixed-instruction processors, MARGE's dynamic instruction set creation provides for efficient use of hardware resources. MARGE processes intermediate code in which each operation is annotated by the bit lengths of the operands. Each basic block (sequence of straight line code) is mapped into a single custom instruction which contains all the operations and logic inherent in the block. A synthesis phase maps the operations comprising the instructions into register transfer level structural components and control logic which have been optimized to exploit functional parallelism and function unit reuse. As a final stage, commercial technology-specific tools are used to generate configuration bit streams for the desired target hardware. Technology- specific pre-placed, pre-routed macro blocks are utilized to implement as much of the hardware as possible. MARGE currently supports the Xilinx-based Splash-2 reconfigurable accelerator and National Semiconductor's CLAy-based parallel accelerator, MAPA. The MARGE approach has been demonstrated on systolic applications such as DNA sequence comparison.

  11. a Discussion about Effective Ways of Basic Resident Register on GIS

    2016-06-01

    In Japan, each municipality keeps a database of every resident's name, address, gender and date of birth called the Basic Resident Register. If the address information in the register is converted into coordinates by geocoding, it can be plotted as point data on a map. This would enable prompt evacuation from disaster, analysis of distribution of residents, integrating statistics and so on. Further, it can be used for not only analysis of the current situation but also future planning. However, the geographic information system (GIS) incorporating the Basic Resident Register is not widely used in Japan because of the following problems: - Geocoding In order to plot address point data, it is necessary to match the Basic Resident Register and the address dictionary by using the address as a key. The information in the Basic Resident Register does not always match the actual addresses. As the register is based on applications made by residents, the information is prone to errors, such as incorrect Kanji characters. - Security policy on personal information In the register, the address of a resident is linked with his/her name and date of birth. If the information in the Basic Resident Register were to be leaked, it could be used for malicious purposes. This paper proposes solutions to the above problems. The suitable solutions for the problems depend on the purpose of use, thus it is important that the purpose should be defined and a suitable way of the application for each purpose should be chosen. In this paper, we mainly focus on the specific purpose of use: to analyse the distribution of the residents. We provide two solutions to improve the matching rate in geocoding. First, regarding errors in Kanji characters, a correction list of possible errors should be compiled in advance. Second, some sort of analyses such as distribution of residents may not require exactly correct position for the address point. Therefore we set the matching level in order: prefecture, city, town, city-block, house-code, house, and decided to accept up to city-block level for the matching. Moreover, in terms of security policy on personal information, some part of information may not be needed for the distribution analysis. For example, the personal information like resident's name should be excluded from the attribute of address point in order to secure the safety operation of the system.

    Possible differences between serum HCG levels in pregnancies achieved after transfer of a single fresh or a vitrified-warmed blastocyst were evaluated. Out of 1130 single blastocyst transfers resulting in positive HCG results, 789 were single fresh blastocyst transfers and 341 single vitrified-warmed blastocyst transfers. The initial serum HCG levels of 869 clinical intrauterine pregnancies were evaluated, 638 after the transfer of a single fresh blastocysts and 231 after the transfer of a single vitrified-warmed blastocysts. The HCG levels from cycles resulting in a clinical intrauterine pregnancy were significantly higher after the transfer of a single vitrified-warmed blastocyst (383 ± 230 IU/l) versus a fresh transfer (334 ± 192 IU/l; P = 0.01). Threshold values for predicting a clinical pregnancy for a fresh blastocyst were 111 IU/l and for a vitrified-warmed blastocyst 137 IU/l. Our study shows that the overall beta-HCG levels are comparable after the transfer of a fresh or vitrified-warmed blastocyst, suggesting that vitrification most probably does not affect the ability of the embryos to produce beta-HCG. This study further shows that when clinicians counsel patients, they should take into account that higher HCG levels are needed after a vitrified-warmed blastocyst transfer to predict a clinical intrauterine pregnancy.

    2014-06-01

    Experts advocate educational programs addressing misinformation regarding donation decisions to increase the potential donor pool. However, few researchers have measured outcomes with nursing students. The purpose of this study was to evaluate the impact of an educational intervention on nursing students' knowledge, attitudes, registering as an organ donor, and family discussions. This quasi-experimental study used a pretest-posttest design with a control group. The research group consisted of 42 volunteers and the control group consisted of 73 volunteers. The written survey included 15 true-false knowledge items and 8 Likert items asking about attitude toward donation, registering as an organ donor, and family discussion. Normally distributed data showed no significant differences between groups on the pretest. The research group had no change in knowledge level 3 months later, but the control group had a significantly decreased knowledge level at that point. More members of the research group than the control group registered as organ donors after the intervention (χ2 = 4.5, P= .03). The control group had no change in registering as an organ donor between the pretest and posttest. Family discussions did not differ significantly from pretest to posttest in either group. One lecture/laboratory experience did make a difference in registering as an organ donor but not in discussing the decision with family members. Students can learn about organ donation from more than one specific class. Recommendations for educators and future research are provided.

    2016-03-01

    The first year turnover rate for newly licensed registered nurses is roughly 30% and increases to about 57% in the second year (Twibell et al., 2012). An effective preceptorship has been shown to better facilitate the first year transition (Hodges et al., 2008) and increase retention rates (Pine and Tart, 2007). The purpose of this study was to examine the relationships between newly licensed registered nurses' perceived preceptor role effectiveness, psychological empowerment and professional autonomy. A prospective, cross-sectional, descriptive research design was used. Sixty-nine newly licensed registered nurses were recruited and surveyed. Newly licensed registered nurses were found to have moderately high levels of perceived preceptor role effectiveness, psychological empowerment, and professional autonomy. Preceptor role effectiveness had significant, moderately, positive relationships with professional autonomy and psychological empowerment. There was also a significant relationship found between professional autonomy and psychological empowerment. Results show that preceptor role effectiveness is linked to increased professional autonomy and psychological empowerment. Therefore, effective preceptorships are necessary in easing the newly licensed registered nurse's transition to practice. Strategies to ensure effective preceptorships and enhance the NRLN's transition to practice are proposed. Copyright © 2016 Elsevier Ltd. All rights reserved.

    This paper revisits hyperspectral data collected from the SpecTIR hyperspectral airborne Rochester Experiment (SHARE) in 2010. It has been determined that there were calibration issues in the SWIR portion of the data. This calibration issue is discussed and has been rectified. Approaches for calibration to radiance and compensation to reflectance are discussed based on in-scene information and radiative transfer codes. In addition to the entire flight line, a much large target detection test and evaluation chip has been created which includes an abundance of potential false alarms. New truth masks are created along with results from target detection algorithms. Co-registered LiDAR data is also presented. Finally, all ground truth information (ground photos, metadata, MODTRAN tape5, ASD ground spectral measurements, target truth masks, etc.), in addition to the HSI flight lines and co-registered LiDAR data, has been organized, packaged and uploaded to the Center for Imaging Science / Digital Imaging and Remote Sensing Lab web server for public use.

    Background Neonatal diabetes has not been previously studied in Ukraine. We investigated the genetic etiology in patients with onset of diabetes during the first 9 months of life. Methods We established a Pediatric Diabetes Register to identify patients diagnosed with diabetes before 9 months of age. Genetic testing was undertaken for 42 patients with permanent or transient diabetes diagnosed within the first 6 months of life (n=22) or permanent diabetes diagnosed between 6 and 9 months (n=20). Results We determined the genetic etiology in 23 of 42 (55%) patients; 86% of the patients diagnosed before 6 months and 20% diagnosed between 6 and 9 months. The incidence of neonatal diabetes in Ukraine was calculated to be 1 in 126,397 live births. Conclusions Genetic testing for patients identified through the Ukrainian Pediatric Diabetes Register identified KCNJ11 and ABCC8 mutations as the most common cause (52%) of neonatal diabetes. Transfer to sulfonylureas improved glycemic control in all 11 patients. PMID:26208381

    We report here on a complete investigation of the excited-state absorption and fluorescence dynamics of Er3+ doped KY3F10 single crystals versus dopant concentrations and optical excitation conditions. Radiative and effective (including non-radiative relaxations) emission lifetimes and branching ratios are determined from a Judd-Ofelt analysis of the absorption spectra and via specific fluorescence experiments using wavelength selective laser excitations. Excited-state absorption and emission spectra are registered within seven spectral domains, i.e. 560 nm, 650 nm, 710 nm, 810 nm, 970 nm, 1550 nm and 2750 nm. A maximum gain cross-section of 0.93 × 10-21 cm2 is determined at the potential laser wavelength of 2.801 μm for a population ratio of 0.48. Saturation of fluorescence intensities and variations of population ratios versus pumping rates are registered and confronted with a rate equation model to derive the rates of the most important up-conversion and cross-relaxation energy transfers occurring at high dopant concentrations.

    In 1987, the first Regional Prostate Cancer Register was set up in the South-East health-care region of Sweden. Other health-care regions joined and since 1998 virtually all prostate cancer (PCa) cases are registered in the National Prostate Cancer Register (NPCR) of Sweden to provide data for quality assurance, bench marking and clinical research. NPCR includes data on tumour stage, Gleason score, serum level of prostate-specific antigen (PSA) and primary treatment. In 2008, the NPCR was linked to a number of other population-based registers by use of the personal identity number. This database named Prostate Cancer data Base Sweden (PCBaSe) has now been extended with more cases, longer follow-up and a selection of two control series of men free of PCa at the time of sampling, as well as information on brothers of men diagnosed with PCa, resulting in PCBaSe 2.0. This extension allows for studies with case-control, cohort or longitudinal case-only design on aetiological factors, pharmaceutical prescriptions and assessment of long-term outcomes. The NPCR covers >96% of all incident PCa cases registered by the Swedish Cancer Register, which has an underreporting of <3.7%. The NPCR is used to assess trends in incidence, treatment and outcome of men with PCa. Since the national registers linked to PCBaSe are complete, studies from PCBaSe 2.0 are truly population based.

    Background. The demands of the current health-care system support the need for more nurses to be prepared at the bachelor's level (American Association of the Colleges of Nursing [AACN], 2007). However, only 28% of the registered nurse (RN) population in Florida holds a bachelor's degree in nursing (BSN), which may be the result of increased…

    Accurate and detailed data on antimicrobial exposure in pig production are essential when studying the association between antimicrobial exposure and antimicrobial resistance. Due to difficulties in obtaining primary data on antimicrobial exposure in a large number of farms, there is a need for a robust and valid method to estimate the exposure using register data. An approach that estimates the antimicrobial exposure in every rearing period during the lifetime of a pig using register data was developed into a computational algorithm. In this approach data from national registers on antimicrobial purchases, movements of pigs and farm demographics registered at farm level are used. The algorithm traces batches of pigs retrospectively from slaughter to the farm(s) that housed the pigs during their finisher, weaner, and piglet period. Subsequently, the algorithm estimates the antimicrobial exposure as the number of Animal Defined Daily Doses for treatment of one kg pig in each of the rearing periods. Thus, the antimicrobial purchase data at farm level are translated into antimicrobial exposure estimates at batch level. A batch of pigs is defined here as pigs sent to slaughter at the same day from the same farm. In this study we present, validate, and optimise a computational algorithm that calculate the lifetime exposure of antimicrobials for slaughter pigs. The algorithm was evaluated by comparing the computed estimates to data on antimicrobial usage from farm records in 15 farm units. We found a good positive correlation between the two estimates. The algorithm was run for Danish slaughter pigs sent to slaughter in January to March 2015 from farms with more than 200 finishers to estimate the proportion of farms that it was applicable for. In the final process, the algorithm was successfully run for batches of pigs originating from 3026 farms with finisher units (77% of the initial population). This number can be increased if more accurate register data can be obtained. The algorithm provides a systematic and repeatable approach to estimating the antimicrobial exposure throughout the rearing period, independent of rearing site for finisher batches, as a lifetime exposure measurement.

    To operate Central Tower Solar Power (CTSP) plants properly, solar collector systems must be able to work under varied weather conditions. Therefore, knowing the state of the atmosphere, and more specifically the level of incident radiation, is essential operational information to adapt the electricity production system to atmospheric conditions. In this work, we analyze the impact of a strong Saharan dust intrusion on the Direct normal irradiance (DNI) registered at two sites 35 km apart in southeastern Spain: the University of Almería (UAL) and the Plataforma Solar de Almería (PSA). DNI can be inputted into the European Solar Radiation Atlas (ESRA) clear sky procedure to derive Linke turbidity values, which proved to be extremely high at the UAL. By using the Simple Model of the Atmospheric Radiative Transfer of Sunshine (SMARTS) at the PSA site, AERONET data from PSA and assuming dust dominated aerosol, DNI estimations agreed strongly with the measured DNI values. At the UAL site, a SMARTS simulation of the DNI values also seemed to be compatible with dust dominated aerosol.

    We have investigated the mechanism of para-hydrogen-induced polarization (PHIP) transfer from the original strongly aligned protons to other nuclei at low external magnetic fields. Although it is known that PHIP is efficiently transferred at low fields, the nature of the transfer mechanism, that is, coherent spin mixing or cross-relaxation, is not well established. Polarization transfer kinetics for individual protons of styrene was, for the first time, measured and modeled theoretically. Pronounced oscillations were observed indicating a coherent transfer mechanism. Spin coherences were excited by passing through an avoided level crossing of the nuclear spin energy levels. Transfer at avoided level crossings is selective with respect to spin order. Our work provides evidence that the coherent PHIP transfer mechanism is dominant at low magnetic fields.

    Ill health in early life has a significant negative impact on school grades, grade repetition, educational level, and labor market outcomes. However, less is known about qualitative socio-economic consequences of a health shock in childhood or adolescence. We investigate the relationship between onset of type 1 diabetes up to age 15 and the probability of choosing and completing a health-oriented path at upper secondary and university level of education. We analyze the Swedish Childhood Diabetes Register, the National Educational Register, and other population registers in Sweden for 2756 people with type 1 diabetes and 10,020 matched population controls. Educational decisions are modeled as unsorted series of binary choices to assess the choice of educational field as a potential mechanism linking early life health to adult outcomes. The analyses reject the hypothesis of no systematic differences in choice of educational field between people with and without type 1 diabetes at both levels. The results are robust to selection on ability proxies and across sensitivity analysis. We conclude that the observed pro health-oriented educational choices among people with type 1 diabetes in our data are consistent with disease onset in childhood and adolescence having qualitative impact on life-course choices.

    The aim of the study was to describe temporal changes in bipolar disorder during 20 years within the Swedish population and to investigate clinical and socioeconomic characteristics, drug treatment, and mortality among patients with bipolar disorder. We conducted a retrospective, nationwide registry study (the Swedish Population Register) that included all patients diagnosed with bipolar disorder (1991-2010) and linked individual data from the Swedish National Patient Register, the National Prescribed Drug Register, and the Population Register (NCT01455961). A cross-sectional cohort analysis was performed for years 2006 versus 2009. Data were analyzed using descriptive statistics. During the study period, the annual incidence of diagnosed bipolar disorder increased 3.5-fold, and patients were diagnosed at a younger age. Mortality among patients with bipolar disorder was twice that of the general population. Compared to an age-standardized population, 30% fewer patients with bipolar disorder were available for work. Among the 40% employed, 64% reported sick leave (46% >100 days/year). Despite similar education levels, disposable income was lower compared to the general population. The most commonly preceding psychiatric diagnoses were depressive or anxiety disorders. Comparing the data for 2006 and 2009 demonstrated similar somatic comorbidity burdens and socioeconomic levels. There was also a decrease in dispensed antipsychotic medications and lithium, while antiepileptic prescriptions increased slightly. Antidepressant dispenses remained virtually unchanged. In Sweden, the incidence and prevalence of diagnosed bipolar disorder have increased during the last 20 years. Compared to the general population, these patients had similar education levels, lower employment levels, less disposable income, more sick leave, and twice the mortality. A trend towards earlier diagnosis, more use of antidepressants, and less use of lithium was seen. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    This work presents a Brain-Computer Interface (BCI) based on Steady State Visual Evoked Potentials (SSVEP), using higher stimulus frequencies (>30 Hz). Using a statistical test and a decision tree, the real-time EEG registers of six volunteers are analyzed, with the classification result updated each second. The BCI developed does not need any kind of settings or adjustments, which makes it more general. Offline results are presented, which corresponds to a correct classification rate of up to 99% and a Information Transfer Rate (ITR) of up to 114.2 bits/min.

    Though all-or-nothing oblivious transfer and one-out-of-two oblivious transfer are equivalent in classical cryptography, we here show that a protocol built upon secure quantum all-or-nothing oblivious transfer cannot satisfy the rigorous definition of quantum one-out-of-two oblivious transfer due to the nature of quantum cryptography. Thus the securities of the two oblivious transfer protocols are not equivalent at the quantum level.

    Are the fetal outcomes of singleton pregnancies that result from cleavage stage embryo transfer (ET) different from the outcomes from Day 5/6 blastocyst stage ET? There was a significantly higher risk of preterm birth (<37 weeks) in singletons after extended embryo culture (Day 5/6) compared with cleavage stage (Day 3) transfer. Two recent studies, from Sweden and the USA, reported an increased risk of preterm birth in singleton pregnancies after Day 5/6 ET compared with Day 3 ET. The US study also showed increased early preterm births and the Swedish study showed increased fetal malformations in this group. A retrospective cohort study was performed. Data were collected from the Canadian ART Register database for all singleton births after fresh IVF/ICSI ET cycles (2001-2009). A total of 12 712 singleton births were included. Of these, 9506 resulted from a Day 3 ET and 3206 resulted from a blastocyst (Day 5/6) ET. Preterm birth rate <37 weeks (unadjusted by potential confounding factors) was higher with Day 5/6 versus Day 3 transfers (17.2 versus 14.1%, P < 0.001). Using logistic regression analysis to adjust for confounding factors, preterm birth rate <37 weeks was the only outcome significantly increased after Day 5/6 compared with Day 3 transfer (odds ratio 1.32, 95% confidence interval 1.17-1.49). The following confounding factors were adjusted for: year of treatment (2001-2009), maternal age (continuous), parity (0 versus ≥1 birth), diagnosis category, number of oocytes retrieved [≤20 versus >20 (high responder group)], insemination method (IVF versus ICSI), number of embryos transferred (1, 2 or ≥3) and the presence of a vanishing twin (≥1 fetal heart on the initial ultrasonographic examination). Post-natal follow-up studies will be required to determine if this difference we observed translates into adverse long-term effects on these offspring. The rate of early preterm births (<32 weeks) was higher in Day 5/6 versus Day 3, but the low number of cases in this category did not have the power to show a difference (3.0 versus 2.7%, P = 0.34). We found a significantly higher risk of preterm birth (<37 weeks) in singletons after extended embryo culture (Day 5/6) compared with cleavage stage (Day 3) transfer, even when adjusting for confounding factors. Our findings are in agreement with the previous two studies; however, we did not show a difference in the very preterm deliveries (unlike the US study) or in fetal malformations (as in the Swedish study). We hypothesize that there may be a deleterious effect of prolonged in vitro embryo culture on subsequent placentation. Longer term follow-up studies will be required to determine if prolonged in vitro culture to the blastocyst stage has an adverse effect on the long-term health of offspring when compared with shorter cleavage stage culture. None.

    To evaluate the effect of the nonsteroidal anti-inflammatory drugs tolfenamic acid and flunixin meglumine in pregnancy rate and embryo survival of recipient mice subjected to embryo transfer. A total of 142 recipient females were transferred with 2,931 embryos and treated with a single injection of tolfenamic acid (1 mg/kg; n = 54 females with 1,129 embryos), flunixin meglumine (2.5 mg/kg; n = 46 females with 942 embryos), or bi-distilled water (10 mL/kg) as control group (n = 42 females with 860 embryos). Pregnancy was checked 2 weeks after embryo transfer, delivery was registered on the due date, and litter size was recorded on Day 7 after birth. Pregnancy rate of tolfenamic acid treated females was significantly higher than flunixin group (P < 0.05) and showed a tendency to be higher when compared to the control group (P = 0.06). The number of pups born from transferred embryos in pregnant females was significantly higher for both treatment groups compared to controls (P < 0.05). Number of pups from total transferred embryos was higher for both treatment groups (P < 0.05) when compared to controls. The use of tolfenamic acid at the time of embryo transfer improves both pregnancy rate and number of live pups in recipient mice, with optimal effects observed with flunixin meglumine. We suggest that the use of tolfenamic acid has beneficial effects on the maintenance of pregnancy and embryo survival in recipient mice, which should be taken into account for further studies in other mammalian females.

    Objective ART has helped millions of infertile couples worldwide to overcome their childlessness. These successes have been accompanied by an increase in multiple deliveries, and perinatal complications associated. The explanation for this complication is the transfer of more than one embryo, to increase the odds of delivery. Our objective was to compare the outcome of elective dual embryo transfer (eDET) to that of the transfer of more than two embryos without embryo cryopreservation (TET), terms of delivery rate and multiple delivery. Methods We analyzed the data registered by 155 clinics members of the RLA: 11,024 eDET and 10,634 TET. Results The delivery rate was significantly higher when eDET was performed than when TET was performed (40.24% and 26.98%, p < 0.001). Also, the ratio of twin deliveries was higher in eDET (25.80% and 20.56%, p < 0.001). However, the ratio of triplets and more deliveries was higher in TET than in eDET (2.34%and 0.52%, p < 0.001). These findings were consistent across the different age categories of the female partner. Conclusion Our findings suggest that eDET was associated with a statistically significant better delivery rate per embryo transfer, and lower ratio of triplet-and-higher deliveries, regardless of the woman’s age. Therefore, there is no evidence that supports the transfer of more than two embryos. PMID:28333027

    In this retrospective study, the relationship between maternal serum oestradiol and progesterone levels after fresh embryo transfer or frozen embryo transfer (FET), and serum beta-HCG levels in early pregnancy and neonatal birth weight was examined. Included for analysis were 5643 conceived singletons: 2610 after FET and 3033 after fresh embryo transfer. Outcome measures included maternal serum oestradiol, progesterone, beta-HCG levels during the peri-implantation period, birth weight and small-for-gestational-age (SGA). Results at 4, 5 and 6 weeks' gestation were as follows: serum oestradiol and progesterone levels were significantly higher in women who underwent fresh embryo transfer compared with FET (all P < 0.0001 except progesterone at 6 weeks; P = 0.009); for fresh embryo transfers, serum beta-HCG levels were significantly lower than in women who underwent FET (P < 0.0001); beta-HCG levels were negatively correlated with serum oestradiol; and birth weight was negatively correlated with serum oestradiol. Incidence of SGA in fresh embryo transfer was increased significantly compared with FET (P < 0.001). Higher maternal oestradiol levels after fresh embryo transfer was correlated with lower beta-HCG in early pregnancy, lower birth weight and higher incidence of SGA.

  15. The Prosody of Topic Transition in Interaction: Pitch Register Variations.

    PubMed

    Riou, Marine

    2017-12-01

    In conversation, speakers can mobilize a variety of prosodic cues to signal a switch in topics. This paper uses a mixed-methods approach combining Conversation Analysis and Instrumental Prosody to investigate the prosody of topic transition in American English, and analyzes the ways in which speakers can play on register level and on register span. A cluster of three prosodic parameters was found to be predictive of transitions: a higher maximum fundamental frequency (F0), a higher median F0 (key), and an expanded register span. Relative to speakers' habitual profiles, the mobilization of such prosodic cues corresponds to a marked upgraded prosodic design. This finding is consistent with the general assumption that continuation constitutes the norm in conversation, and that departing from it, as in the case of a topic transition, requires a marked action and marked linguistic design. The disjunctive action of opening a new topic corresponds to the use of a marked prosodic cue.

  16. The Policy Debate on Pseudonymous Health Registers in Norway

    NASA Astrophysics Data System (ADS)

    Andresen, Herbjørn

    Patient health data has a valuable potential for secondary use, such as decision support on a national level, reimbursement settlements, and research on public health or on the effects of various treatment methods. Unfortunately, extensive secondary use of data has disproportionate negative impact on the patients' privacy. The Norwegian health data processing regulation prescribes four different ways of organizing health registers (anonymous, de-identified, pseudonymous or fully identified data subjects). Pseudonymity is the most innovative of these methods, and it has been available as a legitimate means to achieve extensive secondary use of accurate and detailed data since 2001. Up to now, two different national health registers have been organized this way. The evidence from these experiences should be encouraging: Pseudonymity works as intended. Yet, there is still discernible reluctance against extending the pseudonymity principle to encompass other national health registers as well.

    Accurate articulator-mounted casts are essential for occlusion analysis and for fabrication of dental prostheses. Although the axis orbital plane has been commonly used as the reference horizontal plane, some clinicians prefer to register the horizontal plane with a spirit level when the patient is in the natural head position (NHP) to avoid anatomic landmark variations. This article presents a digital workflow for registering the patient's horizontal plane in NHP on a virtual articulator. An orientation reference board is used to calibrate a stereophotogrammetry device and a 3-dimensional facial photograph with the patient in NHP. The horizontal plane can then be automatically registered to the patient's virtual model and aligned to the virtual articulator at the transverse horizontal axis level. This technique showed good repeatability with positional differences of less than 1 degree and 1 mm in 5 repeated measurements in 1 patient.

    To determine the prevalence of Chlamydia trachomatis infection among registered prostitutes of Durango City and to establish whether there is a correlation between epidemiological factors and infection. Two-hundred-and-forty-seven registered prostitutes of Durango city were studied. Endocervical samples and epidemiological data were obtained. C.trachomatis antigen was detected with the Chlamydiazyme test (Abbott Laboratories, USA.) Forty-one (16.6%) out of 247 prostitutes were positive to C. trachomatis. Thirty-seven out of the 41 positive women had had sexual activity on several States of Mexico (95.1%), as compared to only 109 out of 206 negative women (53.0%) (p < .0001). Prostitutes positive to C. trachomatis (39/41, 95.1%) were more likely to belong to low socioeconomic level than negatives (171/206, 83%) (p = 0.05). The prevalence of C. trachomatis infection was 16.6%. C. trachomatis infection was associated with sexual activity in multiple States of Mexico, and had a tendency to be associated with low socioeconomic level.

  19. Nurses' meaning of caring with patients in acute psychiatric hospital settings: a grounded theory study.

    PubMed

    Chiovitti, Rosalina F

    2008-02-01

    The concept of caring is described as intangible, abstract, and invisible in nursing practice. This has translated into a view of caring as a personal choice or natural obligation rather than a deliberate process. While there has been movement to delineate caring within nursing in general, the psychiatric nurse's perspective on caring has been absent from theoretical works and measures constructed to describe nurse's work. To develop a substantive grounded theory of caring from the perspective of Registered Nurses working with patients in three Canadian acute psychiatric hospital settings. The qualitative research design of grounded theory methodology was used to develop a theory of caring. Three urban, acute psychiatric hospital settings in Canada. Two were general hospitals and one was a psychiatric hospital. Registered Nurses (N=17) licensed with the College of Nurses of Ontario. In-depth interviews with Registered Nurses were conducted using theoretical sampling. The data were analysed using constant comparative analysis. Protective empowering is the basic social psychological process that represents Registered Nurses' caring with patients in acute psychiatric hospital settings. Nurses accomplish protective empowering through six main categories of: (1) respecting the patient; (2) not taking the patient's behaviour personally; (3) keeping the patient safe; (4) encouraging the patient's health; (5) authentic relating; and (6) interactive teaching. The six main categories were accomplished through 27 subcategories. In the theory of protective empowering, the goal is to help patients participate in activities contributing to convalescence, health, and/or quality of life. The theory of protective empowering provides six main categories and 27 subcategories that can be transferred to funding formulas, patient health record documentation systems, nurse orientation and education programs, nurse role descriptions, and used in guiding discussions about organizational values of patient-centred care within a collaborative multidisciplinary context.

  1. Leadership, staffing and quality of care in nursing homes

    PubMed Central

    2011-01-01

    Background Leadership and staffing are recognised as important factors for quality of care. This study examines the effects of ward leaders' task- and relationship-oriented leadership styles, staffing levels, ratio of registered nurses and ratio of unlicensed staff on three independent measures of quality of care. Methods A cross-sectional survey of forty nursing home wards throughout Norway was used to collect the data. Five sources of data were utilised: self-report questionnaires to 444 employees, interviews with and questionnaires to 13 nursing home directors and 40 ward managers, telephone interviews with 378 relatives and 900 hours of field observations. Separate multi-level analyses were conducted for quality of care assessed by relatives, staff and field observations respectively. Results Task-oriented leadership style had a significant positive relationship with two of the three quality of care indexes. In contrast, relationship-oriented leadership style was not significantly related to any of the indexes. The lack of significant effect for relationship-oriented leadership style was due to a strong correlation between the two leadership styles (r = 0.78). Staffing levels and ratio of registered nurses were not significantly related to any of the quality of care indexes. The ratio of unlicensed staff, however, showed a significant negative relationship to quality as assessed by relatives and field observations, but not to quality as assessed by staff. Conclusions Leaders in nursing homes should focus on active leadership and particularly task-oriented behaviour like structure, coordination, clarifying of staff roles and monitoring of operations to increase quality of care. Furthermore, nursing homes should minimize use of unlicensed staff and address factors related to high ratios of unlicensed staff, like low staff stability. The study indicates, however, that the relationship between staffing levels, ratio of registered nurses and quality of care is complex. Increasing staffing levels or the ratio of registered nurses alone is not likely sufficient for increasing quality of care. PMID:22123029

    The aim of this study was to describe the relationship between the transformational leadership of nurse managers and job satisfaction among clinical Registered Nurses at a tertiary care hospital in China. The healthcare system is changing rapidly. Research in Western countries has shown that transformational leadership affects job satisfaction. However, very little research related to this subject has been conducted in healthcare settings in China. The sample consisted of 238 nurses who work at a tertiary care hospital in China. Data were collected from April to August 2006. Research instruments included a demographic data form, a Leadership Practice Inventory and a Job Satisfaction Scale for clinical registered nurses. Both the transformational leadership of nurse managers and job satisfaction among clinical Registered Nurses were at a moderate level. There was a statistically significant positive correlation between the transformational leadership of nurse managers and job satisfaction (r = 0·556, P < 0·001). The findings indicate that the transformational leadership of nurse managers could have an effect on the job satisfaction of clinical Registered Nurses. © 2011 Blackwell Publishing Ltd.

    This study is focused on psychosocial correlates of youth crime in a sample of 2330 Finnish boys born in 1981. Two kinds of data were combined: questionnaires completed by the boys at call-up in 1999 and crime registered in the Finnish National Police Register between 1998 and 2001. One-fifth of the boys were registered to offending during the 4-year period in late adolescence; 14% were registered for one or two offences, 4% for three to five offences, and 3% for more than five offences. Crime accumulated heavily in those with more than five offences, as they accounted for 68% of all crime. Independent correlates of crime were living in a small community, parents' low educational level and divorce, having a regular relationship, self-reported delinquency, daily smoking, and weekly drunkenness, whereas anxious-depressiveness was reversely associated with crime. Most psychosocial problems covaried linearly with offending frequency, being particularly manifested by multiple recidivists. However, recidivists had very rarely used mental health services. The results indicate that offending and various psychosocial problems accumulate in a small minority of boys not reached by mental health services.

    Who owns ocean biodiversity? This is an increasingly relevant question, given the legal uncertainties associated with the use of genetic resources from areas beyond national jurisdiction, which cover half of the Earth’s surface. We accessed 38 million records of genetic sequences associated with patents and created a database of 12,998 sequences extracted from 862 marine species. We identified >1600 sequences from 91 species associated with deep-sea and hydrothermal vent systems, reflecting commercial interest in organisms from remote ocean areas, as well as a capacity to collect and use the genes of such species. A single corporation registered 47% of all marine sequences included in gene patents, exceeding the combined share of 220 other companies (37%). Universities and their commercialization partners registered 12%. Actors located or headquartered in 10 countries registered 98% of all patent sequences, and 165 countries were unrepresented. Our findings highlight the importance of inclusive participation by all states in international negotiations and the urgency of clarifying the legal regime around access and benefit sharing of marine genetic resources. We identify a need for greater transparency regarding species provenance, transfer of patent ownership, and activities of corporations with a disproportionate influence over the patenting of marine biodiversity. We suggest that identifying these key actors is a critical step toward encouraging innovation, fostering greater equity, and promoting better ocean stewardship. PMID:29881777

    Cells treated with RNAlater(TradeMark) have previously been shown to contain antigenic proteins that can be visualized using Western blot analysis. These proteins seem to be stable for several months when stored in RNA stabilizer at 4 C. Antigenic protein can be recovered from cells that have been processed using an Ambion RNAqueous(Registered TradeMark) kit to remove RNA. In this set of experiments, human mixed Mullerian tumor (LNI) cells grown on the International Space Station during Expedition 3 were examined for antigenic stability after removal of RNA. The cells were stored for three months in RNAlater(TradeMark) and RNA was extracted. The RNA filtrate containing the protein was precipitated, washed, and suspended in buffer containing sodium dodecyl sulfate (SDS). Samples containing equal concentrations of protein were loaded onto SDS-polyacrylamide gels. Proteins were separated by electrophoresis and transferred by Western blot to polyvinylidene fluoride (PVDF) membrane. The Western blots were stained with an enhanced chemiluminescent ECL(Registered Trademark) Plus detection kit (Amersham) and scanned using a Storm 840 gel image analyzer (Amersham, Molecular Dynamics). ImageQuant(Registered TradeMark) software was used to quantify the densities of the protein bands. The ground control and flight LN1 cell samples showed a similar staining pattern over time with antibodies to vimentin, glyceraldehyde-3-phosphate dehydrogenase, and epithelial membrane antigens.

    Bipolar disorders (BPD) are chronic mental illnesses, the development of which involves genetic factors and environmental influences. The aim of this paper is to provide an overall description of the Finnish Prenatal Study of Bipolar Disorders (FIPS-B), including the study design, national registers and linkage of the registers. FIPS-B is a population-based prenatal epidemiological study of BPD with a nested case-control study design using several national registers. The registers used are: the Finnish Medical Birth Register (FMBR), the Finnish Hospital Discharge Register (FHDR), the Population Central Register and the Finnish Maternity Cohort (FMC), which are linked using the unique personal identity code (PIC). FIPS-B includes all children born from January 1, 1983 to December 31, 1998 and diagnosed with BPD in Finland by December 31, 2008. The total number of cases included in the FIPS-B is 1887. The age at first diagnosis ranged from 4 to 25 years. Half (50.4%) of the cases utilized only outpatient services, 12.7% only inpatient services and the rest (36.9%) utilized both services. Offspring of mothers with the lowest educational level had an increased odds of BPD (OR = 1.46, 95% CI 1.13-1.88). The cumulative incidence of BPD in the population aged 25 years or younger was 11.6/10,000 in 2008. FIPS-B has all the strengths of a register-based prenatal epidemiological study, along with the availability of maternal biomarkers, enabling it to examine several prenatal, perinatal and familial risk factors for BPD.

    An electronic panel formed by an electronic nose and an electronic tongue has been used to analyse red wines showing high and low phenolic contents, obtained by flash release and traditional soaking, respectively, and processed with or without micro-oxygenation. Four oxygen transfer rate conditions (0.8, 1.9, 8.0, and 11.9 μl oxygen/bottle/day) were ensured by using synthetic closures with controlled oxygen permeability and storage under controlled atmosphere. Twenty-five chemical parameters associated with the polyphenolic composition, the colour indices and the levels of oxygen were measured in triplicate and correlated with the signals registered (seven replicas) by means of the electronic nose and the electronic tongue using partial least squares regression analysis. The electronic nose and the electronic tongue showed particularly good correlations with those parameters associated with the oxygen levels and, in particular, with the influence of the porosity of the closure to oxygen exposure. In turn, the electronic tongue was particularly sensitive to redox species including oxygen and phenolic compounds. It has been demonstrated that a combined system formed from the electronic nose and the electronic tongue provides information about the chemical composition of both the gas and the liquid phase of red wines. This complementary information improves the capacity to predict values of oxygen-related parameters, phenolic content and colour parameters. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Therapeutic hypothermia (HT) has been shown to reduce the risk of death or disability and increase the rate of survival free of -disability at 18-24 months of age in hypoxic-ischemic encephalopathy (HIE). The aim of this study was to take a national survey which (a) evaluated the practice of therapeutic HT for perinatal asphyxia in Austria, (b) evaluated the current clinical management of neonatal HIE and (c) evaluated the need for a national perinatal asphyxia and HT registry. In January 2013, a questionnaire was sent out to the clinical heads of all neonatal level-II and level-III units in Austria. We received replies from all 30 level II and level III units in Austria (response rate 100%). 19 units (63%) answered that they applied HT, 11 units (37%) said they transferred patients for cooling to other units, 3 of those 11 units (27%) said they applied cooling during transport. 25 units (83%) felt the necessity to establish a national registry. The results of this survey show that there is already a high implementation of therapeutic HT in Austria, but there remains a need for information, awareness and training. Problem areas tend to be in the transport of asphyxiated neonates, brain monitoring during cooling and follow-up of affected patients. We believe, that the establishment of national guidelines and a national register could increase awareness for the importance of therapeutic HT in neonatal HIE, thus improve the Austrian management of those infants. © Georg Thieme Verlag KG Stuttgart · New York.

    Congenital malformations in sea turtles have been considered sporadical. Research carried out in the Mexican Pacific revealed high levels of congenital malformations in the olive ridley, but little or no information is available for other species. We present results from analyses of external congenital malformations in olive ridley, green, and hawskbill sea turtles from Mexican rookeries on the Pacific coast and Gulf of Mexico. We examined 150 green and hawksbill nests and 209 olive ridley nests during the 2010 and 2012 nesting seasons, respectively. Olive ridley eggs were transferred to a hatchery and incubated in styrofoam boxes. Nests from the other two species were left in situ. Number of eggs, live and dead hatchlings, and eggs with or without embryonic development were registered. Malformation frequency was evaluated with indices of prevalence and severity. Mortality levels, prevalence and severity were higher in olive ridley than in hawksbill and green sea turtles. Sixty-three types of congenital malformations were observed in embryos, and dead or live hatchlings. Of these, 38 are new reports; 35 for wild sea turtles, three for vertebrates. Thirty-one types were found in hawksbill, 23 in green, and 59 in olive ridley. The head region showed a higher number of malformation types. Malformation levels in the olive ridley were higher than previously reported. Olive ridleys seem more prone to the occurrence of congenital malformations than the other two species. Whether the observed malformation levels are normal or represent a health problem cannot be currently ascertained without long-term assessments. © 2015 Wiley Periodicals, Inc.

  12. Severe hip displacement reduces health-related quality of life in children with cerebral palsy.

    2017-04-01

    Background and purpose - Hip displacement is common in children with severe cerebral palsy (CP) and can cause problems such as pain, contractures, and nursing difficulties. Caregiver priorities and child health index of life with disabilities (CPCHILD) is a recently developed measure of health-related quality of life (HRQL) in children with severe CP. The associations between CPCHILD scores and hip displacement have not been investigated. We explored the effect of hip displacement on HRQL. Patients and methods - 67 children were recruited from the population-based Norwegian CP register. Mean age was 9 (7-12) years. There were 40 boys. Gross motor function classification system (GMFCS) distribution was 12 level III, 17 level IV, and 38 level V. Hip displacement was assessed by radiographic migration percentage (MP). The criterion for hip displacement was MP of the worst hip of ≥40%. Primary caregivers responded to 5 of the 6 domains of the CPCHILD questionnaire. Results - Hip displacement was found in 18 children and it was significantly associated with lower scores on the CPCHILD domains 3 (Comfort and Emotions) and 5 (Health), but not with domains 1 (Activities of Daily Living/Personal Care), 2 (Positioning, Transfer, and Mobility), and 6 (Overall Quality of Life). GMFCS level V was a significant predictor of low scores in all the domains. Interpretation - For the assessment of HRQL in children with severe CP and hip problems, we propose a modified and simplified version of the CPCHILD consisting of 14 of 37 questions. This would reduce the responders' burden and probably increase the response rate in clinical studies without losing important information.

  13. The impact of an emergency fee increase on the composition of patients visiting emergency departments.

    This study aimed to test our hypothesis that a raise in the emergency fee implemented on March 1, 2013 has increased the proportion of patients with emergent symptoms by discouraging non-urgent emergency department visits. We conducted an analysis of 728 736 patients registered in the National Emergency Department Information System who visited level 1 and level 2 emergency medical institutes in the two-month time period from February 1, 2013, one month before the raise in the emergency fee, to March 31, 2013, one month after the raise. A difference-in-difference method was used to estimate the net effects of a raise in the emergency fee on the probability that an emergency visit is for urgent conditions. The percentage of emergency department visits in urgent or equivalent patients increased by 2.4% points, from 74.2% before to 76.6% after the policy implementation. In a group of patients transferred using public transport or ambulance, who were assumed to be least conscious of cost, the change in the proportion of urgent patients was not statistically significant. On the other hand, the probability that a group of patients directly presenting to the emergency department by private transport, assumed to be most conscious of cost, showed a 2.4% point increase in urgent conditions (p<0.001). This trend appeared to be consistent across the level 1 and level 2 emergency medical institutes. A raise in the emergency fee implemented on March 1, 2013 increased the proportion of urgent patients in the total emergency visits by reducing emergency department visits by non-urgent patients.

  14. Excited-State Proton Transfer on the Surface of a Therapeutic Protein, Protamine.

    2017-11-16

    Proton transfer reactions on biosurfaces play an important role in a myriad of biological processes. Herein, the excited-state proton transfer reaction of 8-hydroxypyrene-1,3,6-trisulfonate (HPTS) has been investigated in the presence of an important therapeutic protein, Protamine (PrS), using ground-state absorption, steady-state, and detailed time-resolved emission measurements. HPTS forms a 1:1 complex with Protamine with a high association constant of 2.6 × 10 4 M -1 . The binding of HPTS with Protamine leads to a significant modulation in the ground-state prototropic equilibrium causing a downward shift of 1.1 unit in the acidity constant (pK a ). In contrast to a large number of reports of slow proton transfer of HPTS on biosurfaces, interestingly, HPTS registers a faster proton transfer event in the presence of Protamine as compared to that of even the bulk aqueous buffer medium. Furthermore, the dimensionality of the proton diffusion process is also significantly reduced on the surface of Protamine that is in contrast to the behavior of HPTS in the bulk aqueous buffer medium, where the proton diffusion process is three-dimensional. The effect of ionic strength on the binding of HPTS toward PrS suggests a predominant role of electrostatic interaction between anionic HPTS and cationic Protamine, which is further supported by molecular docking simulations which predict that the most preferable binding site for HPTS on the surface of Protamine is surrounded by multiple cationic arginine residues.

  15. Nursing home spending, staffing, and turnover.

    Recent work on nursing home staffing and turnover has stressed the importance of ownership and resources. However, few studies have examined spending behaviors, which might also influence staffing levels and staff turnover rates. This study investigates whether spending behaviors measured by financial ratios are associated with staffing levels and staff turnover in nursing homes. We analyzed cross-sectional data from 1,014 Texas homes. Data were from the 2002 Texas Nursing Facility Medicaid Cost Report and the 2003 Area Resource File. First, we examined differences in financial ratios by ownership type. Next, the effect of 10 financial ratios on staffing levels and turnover rates for registered nurses, licensed vocational nurses, and certified nursing assistants was examined using robust regression models. Descriptive data indicated that expense ratios related to resident care activities and staff development were significantly higher among not-for-profit than for-profit homes. Higher profits were associated with lower staffing levels, but not higher turnover rates. Administrative expenses (a measure of management capacity) had a negative impact both on staffing levels and staff turnover for licensed vocational nurses and certified nursing assistants, but they did not affect registered nurse staffing. Employee benefit expenses exhibited a positive impact on registered nurse and licensed vocational nurse staffing levels. The addition of information on financial ratios to models predicting staffing indicators reduced the effect of ownership on these indicators. Solutions to the staffing and turnover problem should focus on more effective management practices. Certain levels of administrative and staff benefit expenses may be necessary to improve professional staff recruitment and reduce both staffing and turnover costs. Differences in these financial ratios may partially explain the role played by ownership in determining staffing levels and turnover.

    To develop a pharmacoepidemiologic method for drug utilization analysis according to indication, gender, and age by means of register-based information. Statin utilization in 2005 was applied as an example. Following the recommendations for statin therapy, we constructed an indication hierarchy with eight mutually exclusive levels of register markers of cardiovascular disease and diabetes. Danish residents, as of January 1, 1996, were followed at the individual level in nationwide registers with respect to dispensed prescriptions of cardiovascular drugs and antidiabetics (1996-2005) along with discharge diagnoses and surgical procedures (1977-2005). The highest current possible indication level was assigned to all cohort members. Stratified by indication, gender, and age, statin treatment prevalence and incidence were calculated. Statin treatment prevalence was highest among individuals with myocardial infarction and tended to be higher among men with indications in the upper part of the hierarchy, but it was higher among women (especially the elderly) in the lower part of the hierarchy. Treatment incidence rates followed roughly the same pattern. Women with no register marker or primary hypertension accounted for almost 50% of all incident female users; among men, the figure was 35%. The proportion of incident users with ischemic heart disease or myocardial infarction increased with age. The proposed indication hierarchy provided new insight into prescription patterns of statins. The method can be implemented for other drug categories and could be useful for studying trends in drug utilization, differential drug adherence, and cross-national comparisons.

    The interest of using combined MR and CT information for radiotherapy planning is well documented. However, many planning workstations do not allow to use MR images, nor import predefined contours. This paper presents a new simple approach for transferring segmentation results from MRI to a CT image that will be used for radiotherapy planning, using the same original CT format. CT and MRI images of the same anatomical area are registered using mutual information (MI) algorithm. Targets and organs at risk are segmented by the physician on the MR image, where their contours are easy to track. A locally developed software running on PC is used for this step, with several facilities for the segmentation process. The result is transferred onto the CT by slightly modifying up and down the original Hounsfield values of some points of the contour. This is enough to visualize the contour on the CT, but does not affect dose calculations. The CT is then stored using the original file format of the radiotherapy planning workstation, where the technician uses the segmented contour to design the correct beam positioning. The described method has been tested in five patients. Simulations and patient results show that the dose distribution is not affected by the small modification of pixels of the CT image, while the segmented structures can be tracked in the radiotherapy planning workstation-using adequate window/level settings. The presence of the physician is not requires at the planning workstation, and he/she can perform the segmentation process using his/her own PC. This new approach makes it possible to take advantage from the anatomical information present on the MRI and to transfer the segmentation to the CT used for planning, even when the planning workstation does not allow to import external contours. The physician can draw the limits of the target and areas at risk off-line, thus separating in time the segmentation and planning tasks and increasing the efficiency.

    The purpose of this paper is to describe an assessment of a major retention initiative implemented at The Queen's Medical Center in Honolulu, Hawaii, in response to the nursing workforce shortage in the state. After tracking the situation for several years, nursing leadership at the medical centre critically analysed their registered nurse retention data. The retention rate among new nurses in their first year of employment was only 55·97%. A training programme was initiated to improve registered nurse retention and patient care outcomes with external funding from the US Health Resources and Services Administration. New nurses were supported via additional training and clinical coaches beyond the basic orientation period. Leadership skills of nurse managers were expanded to strengthen their role in retention of new nurses. Four inpatient nursing units became Magnet Pilot Units to demonstrate progress towards achievement of Magnet standards and improvement of patient outcomes. From 2005-2009, first-year-registered nurse retention improved from 55·97-68·20%; registered nurse vacancy rate decreased from 11·26-2·19%; patient satisfaction increased from 84·6-87·8%; registered nurse satisfaction-autonomy improved from 43·55-49·29; registered nurse satisfaction-decision-making went from 41·13-47·97%; and nosocomial decubitus ulcer rate decreased from 15·3-6·7% in the intensive care units. Dedicated resources and targeted activities can make a difference in outcomes for both nurses and patients. Keys to success included engaging staff, having high expectations coupled with high support, providing data to unit-level staff to measure improvements emphasising renewed accountability and maintaining the focus on quality patient care. When the goal is to provide the highest level of quality patient care, professional development of staff and managers is important to meet performance expectations and achieve target clinical goals. Improving registered nurse retention and vacancy rates while also improving patient outcomes had significant human resource and financial benefits for the organisation and contributed to achieving Magnet Recognition. © 2010 Blackwell Publishing Ltd.

  19. Experimental Study of Vane Heat Transfer and Aerodynamics at Elevated Levels of Turbulence

    NASA Technical Reports Server (NTRS)

    Ames, Forrest E.

    1994-01-01

    A four vane subsonic cascade was used to investigate how free stream turbulence influences pressure surface heat transfer. A simulated combustor turbulence generator was built to generate high level (13 percent) large scale (Lu approximately 44 percent inlet span) turbulence. The mock combustor was also moved upstream to generate a moderate level (8.3 percent) of turbulence for comparison to smaller scale grid generated turbulence (7.8 percent). The high level combustor turbulence caused an average pressure surface heat transfer augmentation of 56 percent above the low turbulence baseline. The smaller scale grid turbulence produced the next greatest effect on heat transfer and demonstrated the importance of scale on heat transfer augmentation. In general, the heat transfer scaling parameter U(sub infinity) TU(sub infinity) LU(sub infinity)(exp -1/3) was found to hold for the turbulence. Heat transfer augmentation was also found to scale approximately on Re(sub ex)(exp 1/3) at constant turbulence conditions. Some evidence of turbulence intensification in terms of elevated dissipation rates was found along the pressure surface outside the boundary layer. However, based on the level of dissipation and the resulting heat transfer augmentation, the amplification of turbulence has only a moderate effect on pressure surface heat transfer. The flow field turbulence does drive turbulent production within the boundary layer which in turn causes the high levels of heat transfer augmentation. Unlike heat transfer, the flow field straining was found to have a significant effect on turbulence isotropy. On examination of the one dimensional spectra for u' and v', the effect to isotropy was largely limited to lower wavenumber spectra. The higher wavenumber spectra showed little or no change. The high level large scale turbulence was found to have a strong influence on wake development. The free stream turbulence significantly enhanced mixing resulting in broader and shallower wakes than the baseline case. High levels of flow field turbulence were found to correlate with a significant increase in total pressure loss in the core of the flow. Documenting the wake growth and characteristics provides boundary conditions for the downstream rotor.

    Nurse administrators focus on factors that influence nurses' levels of satisfaction to reduce turnover and improve retention. One important determinant of nurses' satisfaction is the opportunity for professional development. On the basis of feedback from the nurses, a professional development program, Career Advancement for Registered Nurse Excellence, was instituted. The authors describe one approach to create opportunities to improve professional nurse development and the necessity for ongoing assessment of its impact on nurses' job satisfaction.

    2006-10-01

    In the United States, the Emergency Medical Treatment and Active Labor Act defines broad guidelines regarding interhospital transfer of patients who have sought care in the emergency department. However, patient transfers for nonmedical reasons are still considered a common practice. The purpose of this study was to evaluate the possible risk factors for hospital transfer in a population of patients unlikely to require transfer to a level-I center for medical reasons. A retrospective case-control national database study was performed with use of data from the National Trauma Data Bank (version 4.3). The study group consisted of patients with low Injury Severity Scores (< or =9) who were transferred to a level-I trauma center from another hospital. The controls were patients with low Injury Severity Scores who were treated at any hospital that was lower than a level-I trauma center and were not transferred. Hypothesized risk factors for hospital transfer were the age, gender, race, and insurance status of the patient; the time of day the transfer was received; and the number and type of comorbidities. The total sample included 97,393 patients, 21% of whom were transferred to a level-I trauma center. The odds ratios adjusted for all risk factors indicated that transfer rates were higher for male patients compared with female patients (adjusted odds ratio = 1.46), children compared with seniors (3.54), blacks compared with whites (1.28), evening or night transfers compared with morning or afternoon transfers (2.25), patients with Medicaid compared with those with other types of insurance (2.02), and for those with one or more comorbidities compared with those with no comorbidity (2.79). These results suggest the need for prospective studies to further investigate the relationships between hospital transfer and medical and nonmedical factors.

    Until now psychoanalytic training and literature have hardly considered the transference love of homosexual patients. We summarized the scarce literature and related it to the background of our knowledge of heterosexual transference love. The discussion leaves no doubt that, like the heterosexual, homosexual transference love must be read on all levels of psychosexual development instead of reading it on only one and definitely not on an amorphous "preoedipal" level. This is particularly true for the level of the adult homosexual patient, as the case history demonstrates.

    To elucidate factors, other than those clinical, precipitating the risk of aspiration in hospitalized patients. The Critical Incident Technique was adopted for this study in 2015. Three departments located in two academic hospitals in the northeast of Italy, equipped with 800 and 1500 beds, respectively. A purposeful sample of 12 registered nurses (RN), all of whom (i) had reported one or more episodes of aspiration during the longitudinal survey, (ii) had worked ≥3 years in the department, and (iii) were willing to participate, were included. Antecedent factors involved in episodes of aspiration as experienced by RNs were collected through an open-ended interview, and qualitatively analysed. In addition to clinical factors, other factors interacting with each other may precipitate the risk of aspiration episodes during hospitalization: at the nursing care level (misclassifying patients, transferring tasks to other healthcare professionals and standardizing processes to remove potential threats); at the family level (misclassifying patients, dealing with the cultural relevance of eating) and at the environmental level (positioning the patient, managing time pressures, distracting patient while eating, dealing with food consistency and irritating oral medication). At the hospital level, an adequate nursing workforce and models of care delivery, as well as time for initial and continuing patient and family assessment are required. At the unit level, patient-centred models of care aimed at reducing care standardization are also recommended; in addition, nursing, family and environmental factors should be recorded in the incident reports documenting episodes of aspiration. © The Author 2016.

    A chirped laser pulse transfers population from one level to another level accessible by one photon dipole transition. We have used a pair of phase-locked chirped pulses of same frequency instead of a single chirped pulse to achieve phase control over the population transfer and thus creating coherent population distribution in hydrogen molecule. Simultaneous actions of the phase controlled interference and rapid adiabatic passages due to chirped pulses lead to the control in population transfer from the ground X(v = 0, j = 0) level to the C(v = 2, j = 1) level. We have extended this two-level system to a three-level 1 + 1 ladder system for population transfer from the X level to the J(v = 2, j = 2) level via the C intermediate level using two pairs of phase-locked laser chirped pulses and have achieved laudable control over the coherent population distribution.

    Prevalence estimates of ankylosing spondylitis vary considerably, and there are few nationwide estimates. The present study aimed to describe the national prevalence of clinically diagnosed ankylosing spondylitis in Sweden, stratified according to age, sex, geographical, and socio-economic factors, and according to subgroups with ankylosing spondylitis-related clinical manifestations and pharmacological treatment. All individuals diagnosed with ankylosing spondylitis according to the World Health Organization International Classification of Disease codes, between 1967 and 2009, were identified from the National Patient Register. Data regarding disease manifestations, patient demographics, level of education, pharmacological treatment, and geographical region were retrieved from the National Patient Register and other national registers. A total of 11,030 cases with an ankylosing spondylitis diagnosis (alive, living in Sweden, and 16 to 64 years old in December 2009) were identified in the National Patient Register, giving a point prevalence of 0.18% in 2009. The prevalence was higher in northern Sweden, and lower in those with a higher level of education. Men had a higher prevalence of ankylosing spondylitis (0.23% versus 0.14%, P < 0.001), a higher frequency of anterior uveitis (25.5% versus 20.0%, P < 0.001) and were more likely to receive tumor necrosis factor inhibitors than women (15.6% versus 11.8% in 2009, P < 0.001). Women were more likely than men to have peripheral arthritis (21.7% versus 15.3%, P < 0.001), psoriasis (8.0% versus 6.9%, P = 0.03), and treatment with oral corticosteroids (14.0% versus 10.4% in 2009, P < 0.001). This nationwide, register-based study demonstrated a prevalence of clinically diagnosed ankylosing spondylitis of 0.18%. It revealed phenotypical and treatment differences between the sexes, as well as geographical and socio-economic differences in disease prevalence.

    To investigate undergraduate student nurses' and registered nurses' attitudes towards obese persons and towards the management of obese patients. Obesity is a global public health problem. Escalating rates of overweight and obesity are also taking a toll in Asian countries that have historically had much lower rates. Despite the growing prevalence of obesity worldwide, studies show that nurses and other health professionals hold negative attitudes towards obese people, which may affect the care of obese patients. Cross-sectional study. A self-administered questionnaire was completed by 352 undergraduate student nurses and 198 registered nurses. The questionnaire consisted of the Fat Phobia Scale, the Attitudes Toward Obese Adult Patients Scale and a demographic profile. Data were analysed using descriptive statistics and student's t-tests. Overall mean scores on the Fat Phobia Scale (3.53 SD 0.47) indicated average levels of fat phobia and mean scores on the Attitudes Toward Obese Adult Patients scale (2.64 SD 0.51) indicated neutral attitudes towards obese patients. Registered nurses had significantly higher levels of fat phobia and more negative attitudes than did student nurses. The majority of participants perceived that obese people liked food, overate, and were shapeless, slow and unattractive. Additionally, over one-half of participants believed that obese adults should be put on a diet while in hospital. Results of this study show that both registered nurses and student nurses have negative perceptions of obesity and are unlikely to attribute positive characteristics to obese individuals. That registered nurses hold more negative attitudes towards obese person is cause for concern. Given the increasing prevalence of obesity and the disproportionate number of obese persons affected by many health conditions, current and future nurses should have positive professional attitudes towards obese individuals. Obesity needs to be more adequately addressed, both in basic nursing education programs and in continuing professional education for practising nurses.

    To explore the methodologies employed in studies assessing transition of care interventions, with the aim of defining goals for the improvement of future studies. Systematic review of comparative studies assessing transition to adult care interventions for young people with chronic conditions. MEDLINE, EMBASE, ClinicalTrial.gov. 2 reviewers screened comparative studies with experimental and quasi-experimental designs, published or registered before July 2015. Eligible studies evaluate transition interventions at least in part after transfer to adult care of young people with chronic conditions with at least one outcome assessed quantitatively. 39 studies were reviewed, 26/39 (67%) published their final results and 13/39 (33%) were in progress. In 9 studies (9/39, 23%) comparisons were made between preintervention and postintervention in a single group. Randomised control groups were used in 9/39 (23%) studies. 2 (2/39, 5%) reported blinding strategies. Use of validated questionnaires was reported in 28% (11/39) of studies. In terms of reporting in published studies 15/26 (58%) did not report age at transfer, and 6/26 (23%) did not report the time of collection of each outcome. Few evaluative studies exist and their level of methodological quality is variable. The complexity of interventions, multiplicity of outcomes, difficulty of blinding and the small groups of patients have consequences on concluding on the effectiveness of interventions. The evaluation of the transition interventions requires an appropriate and common methodology which will provide access to a better level of evidence. We identified areas for improvement in terms of randomisation, recruitment and external validity, blinding, measurement validity, standardised assessment and reporting. Improvements will increase our capacity to determine effective interventions for transition care. Published by the BMJ Publishing Group Limited.

    We evaluated an association between episodes of high SO{sub 2} pollution of the air and school absenteeism during a 2-y period. Data on absenteeism were collected from 84 elementary schools in the first year and 111 schools in the second year. The schools were selected for their proximity to air pollution monitoring stations. The data were used as a nonspecific, but sensitive health indicator. Sulfur dioxide was selected because it was almost continuously available. The correlation between SO{sub 2} and absenteeism was assessed using the Box-Jenkins approach for the analysis of time series to correct for autocorrelation within the timemore » series. Next, the data were recalculated to a weekly figure to correct for influenza epidemics, as indicated by a countrywide monitoring program of general practitioners. The country was divided into four regions in accordance with data on influenza. We used a first-order moving-average transfer model, which assumed the absenteeism due to influenza was in proportion to the data on influenza reported for the whole population. Using this model, absenteeism was estimated and subtracted from the observed absenteeism. The residuals were correlated with the data on air pollution after correction for autocorrelation. We found a relationship between absenteeism and air pollution, with a delay of 1 to 2 wk. There is a clear relationship between influenza as registered by the general practitioners and air pollution as indicated by the level of SO{sub 2}. After correction for influenza by the transfer model, the correlation between air pollution and school absenteeism is reduced to being barely significant.« less

    Public and private entities in the United States spend billions of dollars each year on potentially avoidable hospitalizations. This is a common occurrence in long-term care (LTC) facilities, especially in rural jurisdictions. This article details the creation of a telemedicine approach to assess residents from rural LTC facilities for potential transfer to hospitals. An electronic LTC (eLTC) pilot was conducted in 20 pilot LTC facilities from 2012-2015. Each site underwent technologic assessment and upgrading to ensure that 2-way video communication was possible. A new central "hub" was staffed with advanced practice providers and registered nurses. Long-term care pilot sites were trained and rolled out over 3 years. This article reports development and implementation of the pilot, as well as descriptive statistics associated with provider assessments and averted transfers. Over 3 years, 736 eLTC consultations occurred in pilot sites. One-quarter of consultations occurred between 10 pm and 9 am. Overall, approximately 31% of cases were transferred. This decreased from 54% of cases in 2013 to 17% in 2015. Rural pilot facilities had an average of 23 eLTC consults per site per year. Averted transfers represent a dramatic benefit to the residents, as potentially avoidable hospitalizations cause undue stress and allow for nosocomial infections, among other risks. In addition, averting these unnecessary transfers likely saved the taxpayers of the United States over $5 million in admission-related charges to Centers for Medicare and Medicaid Services (511 avoided transfers × $11,000 per average hospitalization from a LTC facility). Overall, the eLTC pilot showed promise as a proof-of-concept. The pilot's implementation resulted in increasing utilization and promising reductions in unnecessary transfers to emergency departments and hospitalizations.

    2012-06-01

    To develop and evaluate a tool that can improve the accuracy of contour transfer between different image modalities under challenging conditions of low image contrast and large image deformation, comparing to a few commonly used methods, for radiation treatment planning. The software tool includes the following steps and functionalities: (1) accepting input of images of different modalities, (2) converting existing contours on reference images (e.g., MRI) into delineated volumes and adjusting the intensity within the volumes to match target images (e.g., CT) intensity distribution for enhanced similarity metric, (3) registering reference and target images using appropriate deformable registration algorithms (e.g., B-spline, demons) and generate deformed contours, (4) mapping the deformed volumes on target images, calculating mean, variance, and center of mass as the initialization parameters for consecutive fuzzy connectedness (FC) image segmentation on target images, (5) generate affinity map from FC segmentation, (6) achieving final contours by modifying the deformed contours using the affinity map with a gradient distance weighting algorithm. The tool was tested with the CT and MR images of four pancreatic cancer patients acquired at the same respiration phase to minimize motion distortion. Dice's Coefficient was calculated against direct delineation on target image. Contours generated by various methods, including rigid transfer, auto-segmentation, deformable only transfer and proposed method, were compared. Fuzzy connected image segmentation needs careful parameter initialization and user involvement. Automatic contour transfer by multi-modality deformable registration leads up to 10% of accuracy improvement over the rigid transfer. Two extra proposed steps of adjusting intensity distribution and modifying the deformed contour with affinity map improve the transfer accuracy further to 14% averagely. Deformable image registration aided by contrast adjustment and fuzzy connectedness segmentation improves the contour transfer accuracy between multi-modality images, particularly with large deformation and low image contrast. © 2012 American Association of Physicists in Medicine.

    To understand: (1) staff perceptions of best practice for information transfer for multitrauma patients on discharge from the emergency department; (2) what information should be conveyed at transfer and (3) how information is transferred. Information transfer for multitrauma patients is an integral factor for continuity of care, safety, quality assurance and patient outcomes; however, this has not been the focus of previous studies. This was a qualitative study using focus group interviews. Data were collected during focus group interviews across five clinical areas. Themes were derived from the data with consensus from three data coders. Purposive sampling was used and included staff caring for trauma patients during patient transition out of the emergency department. Participants were representatives of the emergency department, perioperative care, intensive care unit, high dependency care unit and the trauma service unit. Twenty-six registered nurses and two medical officers participated. Five focus group interviews were held. Themes emerged from the data including 'Variability', 'Continuity' and 'Putting the pieces together'. The first three themes were all influenced by the fourth theme of 'Values/Context'. Considered together these themes influenced staff perception of the quality of information transfer for multitrauma patients on discharge from the emergency department. Staff perceived best practice for information transfer to be clear, concise, relevant documentation that travelled with the patient and interactive communication at handover that adhered to agreed principles and a minimum data set specific to trauma patients. Clinicians involved in handover need to actively listen, avoiding 'doing' at the same time, be aware of essential questions to ask about the patient. An agreed expectation between different clinical areas needs to exist about information transfer to reduce variability. The minimum data required to provide ongoing safe care for multitrauma patients are identified. © 2016 John Wiley & Sons Ltd.

    Long-term growth hormone (GH) treatments in short children born small for gestational age (SGA) restore lipid metabolism, but also increase insulin resistance. The aim of this study was to evaluate the influence of long-term GH therapy on lipid and glucose metabolism as well as its dose dependency in short Japanese children born SGA. Eighty Japanese children with a short stature who were born SGA participated in this study; 65 were treated with fixed GH doses of 0.033 (low) or 0.067 (high) mg/kg/day for 260 weeks; 15 were untreated controls in the first year and were randomized to one of the two treatment groups at week 52. Serum cholesterol, glucose and insulin levels were regularly measured. An oral glucose tolerance test (OGTT) was conducted annually. The mean age at the start of GH therapy was approximately 5.3 years. Serum total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) in the high dose group significantly decreased over time during GH therapy. In both dose groups for TC, and in the high dose group for LDL-C, the higher the baseline values, the greater the decrease after 260 weeks. The rate of the decrease observed after 260 weeks in patients with high LDL-C levels was greater in the high dose group. Based on the results of OGTT, no patient was classified as being diabetic; however, annual increases were observed in post-OGTT insulin levels. After 260 weeks, the homeostasis model assessment as an index of insulin resistance (HOMA-IR) increased, suggesting that insulin resistance developed over time with the GH treatment, while 36.6 % of the subjects entered puberty. Long-term continuous GH treatment for children born SGA may have a potentially beneficial effect on several parameters in lipid metabolism and does not adversely affect glucose metabolism.

    Objective To assess whether A level grades (achievement) and intelligence (ability) predict doctors' careers. Design Prospective cohort study with follow up after 20 years by postal questionnaire. Setting A UK medical school in London. Participants 511 doctors who had entered Westminster Medical School as clinical students between 1975 and 1982 were followed up in January 2002. Main outcome measures Time taken to reach different career grades in hospital or general practice, postgraduate qualifications obtained (membership/fellowships, diplomas, higher academic degrees), number of research publications, and measures of stress and burnout related to A level grades and intelligence (result of AH5 intelligence test) at entry to clinical school. General health questionnaire, Maslach burnout inventory, and questionnaire on satisfaction with career at follow up. Results 47 (9%) doctors were no longer on the Medical Register. They had lower A level grades than those who were still on the register (P < 0.001). A levels also predicted performance in undergraduate training, performance in postregistration house officer posts, and time to achieve membership qualifications (Cox regression, P < 0.001; b=0.376, SE=0.098, exp(b)=1.457). Intelligence did not independently predict dropping off the register, career outcome, or other measures. A levels did not predict diploma or higher academic qualifications, research publications, or stress or burnout. Diplomas, higher academic degrees, and research publications did, however, significantly correlate with personality measures. Conclusions Results of achievement tests, in this case A level grades, which are particularly used for selection of students in the United Kingdom, have long term predictive validity for undergraduate and postgraduate careers. In contrast, a test of ability or aptitude (AH5) was of little predictive validity for subsequent medical careers. PMID:12869457

    Previous studies have revealed inequalities in stroke treatment based on demographics, hospital type, and region. We used the Swedish Stroke Register (Riksstroke) to test whether patient education level is associated with reperfusion (either or both of thrombolysis and thrombectomy) treatment. We included 85 885 patients with ischemic stroke aged 18 to 80 years registered in Riksstroke between 2003 and 2009. Education level was retrieved from Statistics Sweden, and thrombolysis, thrombectomy, patient, and hospital data were obtained from Riksstroke. We used multivariable logistic regression to analyze the association between reperfusion therapy and patient education. A total of 3649 (4.2%) of the patients received reperfusion therapy. University-educated patients were more likely to be treated (5.5%) than patients with secondary (4.6%) or primary education (3.6%; P<0.001). The inequality associated with education was still present after adjustment for patient characteristics; university education odds ratio, 1.14; 95% confidence interval, 1.03 to 1.26 and secondary education odds ratio, 1.08; 95% confidence interval, 1.00 to 1.17 compared with primary education. Higher hospital specialization level was also associated with higher reperfusion levels (P<0.001). In stratified multivariable analyses by hospital type, significant treatment differences by education level existed only among large nonuniversity hospitals (university education odds ratio, 1.20; 95% confidence interval, 1.04-1.40; secondary education odds ratio, 1.14; 95% confidence interval, 1.01-1.29). We demonstrated a social stratification in reperfusion, partly explained by patient characteristics and the local hospital specialization level. Further studies should address treatment delays, stroke knowledge, and means to improve reperfusion implementation in less specialized hospitals. © 2014 American Heart Association, Inc.

    Executive functions are higher cognitive control functions, which are essential to physical and psychological well-being, academic performance, and healthy social relationships. Executive functions can be trained, albeit without broad transfer, to this date. Broad transfer entails the translation of improved cognitive functions to daily life (behaviors). The intervention Train your Mind was designed to train executive functions among elementary school children aged 9 to 11 years, and obtain broad transfer in terms of enhanced physical activity, healthy eating, and socioemotional regulation. This paper aims to describe the cluster randomized trial to test the effectiveness of the Train your Mind intervention. Train your Mind was integrated into the existing school curriculum for 8 months (25 weeks excluding holidays). The effectiveness of the intervention was tested in a cluster randomized trial comprising 13 schools, 34 groups (school classes), and 800 children, using a battery of 6 computer tasks at pre- and postmeasurement. Each of the 3 core executive functions was measured by 2 tasks (Flanker and Go/No-Go; N-Back and Running Span; Attention Switching Task and Dots/Triangles). Moreover, we administered questionnaires that measure emotion-regulation, cognitive errors, physical activity, dietary habits, and the psycho-social determinants of diet and physical activity. Body mass index was also measured. Multilevel analyses will account for clustering at the school and group levels, and randomization took place at the school level. Results are currently being analyzed. The main purpose of this study is to test Train your Mind's effectiveness in enhancing executive functions. Second, we investigate whether increased executive functions lead to improved physical activity and healthy eating. If found effective, executive function training could easily be integrated into school curricula everywhere, and as such, boost health, academic performance, and emotion-regulation of elementary school children, in a cost-effective manner.

    The purpose of this study was to conduct a systematic review to determine the effectiveness of virtual reality (VR) training in orthopaedic surgery. A comprehensive systematic review was performed of articles of VR training in orthopaedic surgery published up to November 2014 from MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials databases. We included 10 relevant trials of 91 identified articles, which all reported on training in arthroscopic surgery (shoulder, n = 5; knee, n = 4; undefined, n = 1). A total of 303 participants were involved. Assessment after training was made on a simulator in 9 of the 10 studies, and in one study it took place in the operating room (OR) on a real patient. A total of 32 different outcomes were extracted; 29 of them were about skills assessment. None involved a patient-related outcome. One study focused on anatomic learning, and the other evaluated technical task performance before and after training on a VR simulator. Five studies established construct validity. Three studies reported a statistically significant improvement in technical skills after training on a VR simulator. VR training leads to an improvement of technical skills in orthopaedic surgery. Before its widespread use, additional trials are needed to clarify the transfer of VR training to the OR. Systematic review of Level I through Level IV studies.

    In this nationwide matched cohort study, we have investigated whether being born with hypospadias affect subsequent psychosocial outcomes in adulthood. We analyzed prospectively collected data from national Swedish registers. Data on the diagnoses were collected from the National Patient Register and the Medical Birth Register. Data on psychosocial outcomes such as educational and income level, marital status and disability pension were collected from Statistics Sweden. The effects of covariates, such as age, county of birth, presence of other malformations and psychiatric illness, were taken into account. The associations between hypospadias and psychosocial outcomes were calculated using conditional logistic regression and expressed as odds ratios (OR) and 95% confidence intervals (CI). We included 4378 men diagnosed with hypospadias, born between 1969 and 1993 in Sweden. Patients with hypospadias were matched with unaffected men by year of birth and birth county. We did not detect any differences in educational or income level. The probability of entering marriage (OR 1.02, 95% CI 0.90–1.14) did not differ, regardless of phenotype. We did, however, detect a 40% increased probability of receiving a disability pension, (OR 1.39, 95% CI 1.20–1.61). In conclusion, men born with hypospadias in Sweden do not differ from unaffected men with respect to the majority of psychosocial outcomes studied. They are, however, at increased risk of receiving a disability pension, which motivates further investigations. PMID:28384289

    Cerebrovascular diseases are the second-highest cause of death in South Korea (9.6% of all causes of mortality in 2013). South Korea has a shortage of trained medical personnel compared with other countries and the demands for health care are continuously increasing. Our study sought to determine the relationship between hospital human resources and the outcomes of stroke patients. We used data from NHI claims (n=99,464) at 120 hospitals to analyze readmission or death within 30 days after discharge or hospitalization for stroke patients during 2010-2013. We used multilevel models that included both patient-level and hospital-level variables to examine factors associated with readmission or death within 30 days. A total of 1782 (1.8%) patients were readmitted within 30 days, and death occurred within 30 days for 6926 (7.0%) patients. Patients cared for by a higher percentages of specialists or registered nurses had a lower risk of readmission or death within 30 days (readmission per 10% increase in registered nurses, OR=0.89 and SD=0.85-0.94; death per 10% increase in specialists, OR=0.93 and SD=0.89-0.98). The percentages of specialist and registered nurses caring for stroke patients were positively correlated with better patient outcomes, particularly for patients with cerebral infarction.

    The Optimizing Patient Transfers, Impacting Medical Quality, and Improving Symptoms: Transforming Institutional Care (OPTIMISTIC) project aims to reduce avoidable hospitalizations of long-stay residents enrolled in 19 central Indiana nursing facilities. This clinical demonstration project, funded by the Centers for Medicare and Medicaid Services Innovations Center, places a registered nurse in each nursing facility to implement an evidence-based quality improvement program with clinical support from nurse practitioners. A description of the model is presented, and early implementation experiences during the first year of the project are reported. Important elements include better medical care through implementation of Interventions to Reduce Acute Care Transfers tools and chronic care management, enhanced transitional care, and better palliative care with a focus on systematic advance care planning. There were 4,035 long-stay residents in 19 facilities enrolled in OPTIMISTIC between February 2013 and January 2014. Root-cause analyses were performed for all 910 acute transfers of these long stay residents. Of these transfers, the project RN evaluated 29% as avoidable (57% were not avoidable and 15% were missing), and opportunities for quality improvement were identified in 54% of transfers. Lessons learned in early implementation included defining new clinical roles, integrating into nursing facility culture, managing competing facility priorities, communicating with multiple stakeholders, and developing a system for collecting and managing data. The success of the overall initiative will be measured primarily according to reduction in avoidable hospitalizations of long-stay nursing facility residents. © 2014, Copyright the Authors Journal compilation © 2014, The American Geriatrics Society.

    Charge coupled devices represent unique usage of the metal oxide semiconductor concept. These devices can sample an AC signal at the input, transfer charge proportional to this signal through the CCD shift register and then provide an output of the same frequency and shape as the input. The delay time between input and output is controlled by the CCD operating frequency and the number of stages in the shift resistor. This work is a reliability evaluation of the buried channel and surface channel CCD technologies. The constructions are analyzed, failure modes are described, and test results are reported.

    In this article, the authors evaluate a Swedish pilot scheme that targeted immigrants with weak Swedish-language skills registered as unemployed at public employment offices. By sandwiching work-oriented language teaching and practical workplace training, the project aimed at enhancing the employability of project participants but also at alerting them to and preparing them for available training and further education opportunities. For the evaluation, a comparison group of nonparticipants was selected using a propensity score methodology. The results show that participation in the pilot scheme project resulted in much speedier transfers from open unemployment to employment, training, and education.

    To determine the factors that attract and retain Registered Nurses in the first-line nurse manager role. The first-line nurse manger role is pivotal in health-care organisations. National demographics suggest that Canada will face a first-line nurse manager shortage because of retirement in the next decade. Determination of factors that attract and retain Registered Nurses will assist organisations and policy makers to employ strategies to address this shortage. The study used an exploratory, descriptive qualitative approach, consisting of semi-structured individual interviews with 11 Registered Nurses in first-line nurse manager roles. The findings revealed a discrepancy between the factors that attract and retain Registered Nurses in the first-line nurse manager role, underscored the importance of the mentor role and confirmed the challenges encountered by first-line nurse managers practicing in the current health-care environment. The first-line nurse manager role has been under studied. Further research is warranted to understand which strategies are most effective in supporting first-line nurse managers. Strategies to support nurses in the first-line nurse manager role are discussed for the individual, programme, organisation and health-care system/policy levels. © 2013 John Wiley & Sons Ltd.

    To develop a method to estimate vaccination coverage using both a computerized vaccine registry with an unknown underreporting rate and a seroprevalence study. A real example of a meningococcal C conjugate vaccine (MCCV) coverage estimation is studied to illustrate the proposed methodology. We reviewed the Vaccine Information System of Valencia (Sistema de Información Vacunal, SIV) for the MCCV status of 1430 subjects aged 3-29 years as part of a seroprevalence study. When MCCV was not registered in SIV, subjects were classified into three groups (MCCV non-registered, no vaccination records and missing information) depending on the registry of other vaccines. A Bayesian model was developed to ascertain the percentage of MCCV-vaccinated subjects based on the meningococcal C seroprotection levels from the seroprevalence study. The seroprotection levels in subjects with no MCCV registered in SIV (358) were similar to those in subjects with MCCV registered (1072). This indicated a large proportion of vaccinated subjects with no MCCV registered. The estimated vaccine coverage was over 80% in all age groups, except >22 years, where it was 67.6% (95% CI: [54.0-80.4]), which corresponded to those aged over 13 years at the time of the catch-up campaign. An underreporting rate of 23.5-73.4%, depending on the age group, was estimated in those vaccinated in the 2002 catch-up campaign. The Bayesian model allowed for a more realistic estimation of MCCV uptake. In this example, we quantified the underreporting of a vaccine registry, especially occurring during a catch-up campaign that occurred at the establishment of the registry. Copyright © 2015.

    The influence of triplet levels on Förster resonance energy transfer via singlet levels in donor-acceptor (D-A) pairs is studied. Four types of D-A pair are considered: (i) two-level donor and two-level acceptor, (ii) three-level donor and two-level acceptor, (iii) two-level donor and three-level acceptor, and (iv) three-level donor and three-level acceptor. If singlet-triplet transitions in a three-level acceptor molecule are ineffective, the energy transfer efficiency E=I_{A}/(I_{A}+I_{D}), where I_{D} and I_{A} are the average intensities of donor and acceptor fluorescence, can be described by the simple theoretical equation E(F)=FT_{D}/(1+FT_{D}). Here F is the rate of energy transfer, and T_{D} is the donor fluorescence lifetime. In accordance with the last equation, 100% of the donor electronic energy can be transferred to an acceptor molecule at FT_{D}≫1. However, if singlet-triplet transitions in a three-level acceptor molecule are effective, the energy transfer efficiency is described by another theoretical equation, E(F)=F[over ¯](F)T_{D}/[1+F[over ¯](F)T_{D}]. Here F[over ¯](F) is a function of F depending on singlet-triplet transitions in both donor and acceptor molecules. Expressions for the functions F[over ¯](F) are derived. In this case the energy transfer efficiency will be far from 100% even at FT_{D}≫1. The character of the intensity fluctuations of donor and acceptor fluorescence indicates which of the two equations for E(F) should be used to find the value of the rate F. Therefore, random time instants of photon emission in both donor and acceptor fluorescence are calculated by the Monte Carlo method for all four types of D-A pair. Theoretical expressions for start-stop correlators (waiting time distributions) in donor and acceptor fluorescence are derived. The probabilities w_{N}^{D}(t) and w_{N}^{A}(t) of finding N photons of donor and acceptor fluorescence in the time interval t are calculated for various values of the energy transfer rate F and for all four types of D-A pair. Comparison of the calculated D and A fluorescence trajectories with those measured by Weiss and co-workers proves the important role of triplet levels in energy transfer via singlet levels.

    A random-digit dialed telephone survey was conducted in a traditionally conservative southern state to determine the level of support for sexuality education in the public schools including support for specific sexuality education topics, the earliest grade level at which each topic should be taught, and the amount of instruction time required for sexuality education in the high schools. Survey data were obtained from 534 South Carolina registered voters in late January/early February 1997. Results demonstrated that most South Carolina registered voters: 1) supported sexuality education in the public schools; 2) supported instruction on a variety of sexuality education topics; 3) supported instruction at all grade levels, especially beginning in middle school; and 4) believed instruction time for sexuality education in the high schools should either remain the same or be increased. In addition, a significant increase in support for sexuality education occurred from the beginning of the survey to the end, suggesting that the instrument itself may have served as an educational tool for respondents. The characteristics of registered voters who supported sexuality education at the beginning of the survey and at the end were examined and compared. These results may assist in the development of educational and marketing strategies designed to build support for school-based sexuality education programs in South Carolina and elsewhere.

    To elucidate registered nurses' experiences of coordinated care planning in outpatient care. Coordinated care planning has been studied from the perspectives of both patients and nurses in inpatient care, but it is deficient in outpatient care. Qualitative content analysis of interviews with 10 registered nurses participating in two focus groups. An overall theme was identified: creating concordant communication in relation to patient and health-care providers. The result is based on four categories and nine subcategories. Nurses need extraordinary communication skills to reach concordance in outpatient care planning. In addition to involving and supporting the patients and next of kin in the decision-making process, the outcome of the nursing process must be understood by colleagues and members of other professions and health-care providers (non-nursing). An effective outpatient care-planning process requires that care managers understand the impact of communicating, transferring information and reaching consensus with other health-care providers, actively supporting employees in the outpatient care-planning process and contributing to the development of common goals and policy documents across organisational boundaries. © 2012 Blackwell Publishing Ltd.

    Liquid radioactive waste from the Mayak Production Association (Chelyabinsk Region, Russia) is contained in industrial reservoirs (R-11, R-10, R-4, R-17, and R-9) that have different levels of radioactive contamination, increased from R-11 to R-17. A study of the ecosystems in these reservoirs was performed in 2009 to determine if there was any association with the level of contamination. No significant change in the status of biota was found in the reservoir with the lowest radionuclide concentrations (R-11) in comparison to other reservoirs in the region with a similar geography that are unaffected by radioactive contamination. In reservoir R-10, changes in the zoobenthos indices were registered. In reservoir R-4, changes in the zoobenthos and zooplankton communities were registered. In reservoir R-17, there was no ichthyofauna, but strong changes in the phytoplankton, zooplankton, and zoobenthos communities were registered. In reservoir R-9, under the conditions of the heaviest radioactive contamination of water ecosystems in the biosphere, there was no ichthyofauna, and phytoplankton and zooplankton consisted of almost a monoculture of cyanobacteriae and rotifers.

    Inhibitors of the sodium-glucose co-transporter 2 (SGLT2) promote the excretion of glucose to reduce glycated hemoglobin (HbA1c) levels. Canagliflozin was the first SGLT2 inhibitor to be approved by the US FDA for use in the treatment of type 2 diabetes, and recently dapagliflozin has also been approved. We evaluated a recent Phase III clinical trial with dapagliflozin. Dapagliflozin was studied as add-on therapy to sitagliptin with or without metformin, and was shown to lower HbA1c levels and body weight. The incidence of hypoglycaemia was low with dapagliflozin, but it did increase the incidence of urogenital infections. As no clear benefits have been identified for dapagliflozin over canagliflozin, which was the first gliflozin registered by the FDA, we do not fully understand why it was necessary to register dapagliflozin. Given that there are no completed cardiovascular/clinical outcome studies with dapagliflozin, and therefore no evidence of beneficial effect, it also seems premature to be using it extensively or considering it as an alternative to the clinically proven metformin.

    Sustainability is the ability of a system to be maintained over the long term. Resilience is the ability of a system to withstand disturbances and continue to function in a sustainable manner. Issues of sustainability and resilience apply to all aspects of nutrition and dietetics practice, can be practiced at both the program and systems level, and are broader than any one specific practice setting or individual intervention. Given an increasing need to apply principles of sustainability and resilience to nutrition and dietetics practice, as well as growing interest among the public and by Registered Dietitian Nutritionists of health issues related to food and water systems, the Hunger and Environmental Nutrition Dietetic Practice Group, with guidance from the Academy of Nutrition and Dietetics Quality Management Committee, has developed the Standards of Professional Performance as a tool for Registered Dietitian Nutritionists working in sustainable, resilient, and healthy food and water systems to assess their current skill levels and to identify areas for further professional development in this emerging practice area. This Standards of Professional Performance document covers six standards of professional performance: quality in practice, competence and accountability, provision of services, application of research, communication and application of knowledge, and utilization and management of resources. Within each standard, specific indicators provide measurable action statements that illustrate how sustainable, resilient, and healthy food and water systems principles can be applied to practice. The indicators describe three skill levels (competent, proficient, and expert) for Registered Dietitian Nutritionists working in sustainable, resilient, and healthy food and water systems.

    Modern metadata systems strive to help scientists locate data relevant to their research and then retrieve them quickly. Success of this mission depends on the organization and completeness of metadata. Each relevant data resource has to be registered; each content has to be described; each data file has to be accessible. Ultimately, data discoverability is about the practical ability to describe data content and location. Correspondingly, data registration has a "Parameter" level, at which content is specified by listing available observed properties (parameters), and a "Granule" level, at which download links are given to data records (granules). Until recently, both parameter- and granule-level data registrations were accomplished at NASA Virtual System Observatory easily by listing provided parameters and building Granule documents with URLs to the datafile locations, usually those at NASA CDAWeb data warehouse. With the introduction of the Virtual Wave Observatory (VWO), however, the parameter/granule concept faced a scalability challenge. The wave phenomenon content is rich with descriptors of the wave generation, propagation, interaction with propagation media, and observation processes. Additionally, the wave phenomenon content varies from record to record, reflecting changes in the constituent processes, making it necessary to generate granule documents at sub-minute resolution. We will present the first success story of registering 234,178 records of IMAGE Radio Plasma Imager (RPI) plasmagram data and Level 2 derived data products in ESPAS (near-Earth Space Data Infrastructure for e-Science), using the VWO-inspired wave ontology. The granules are arranged in overlapping display and numerical data collections. Display data include (a) auto-prospected plasmagrams of potential interest, (b) interesting plasmagrams annotated by human analysts or software, and (c) spectacular plasmagrams annotated by analysts as publication-quality examples of the RPI science. Numerical data products include plasmagram-derived records containing signatures of local and remote signal propagation, as well as field-aligned profiles of electron density in the plasmasphere. Registered granules of RPI observations are available in ESPAS for their content-targeted search and retrieval.

    The Alaska earthquake of March 27, 1964, had widespread hydrologic effects throughout practically all of the United States. More than 1,450 water-level recorders, scattered throughout all the 50 States except Connecticut, Delaware, and Rhode Island, registered the earthquake. Half of the water-level records were obtained from ground-water observation wells and half at surface-water gaging stations. The earthquake is also known to have registered on water-level recorders on wells in Canada, England, Denmark, Belgium, Egypt, Israel, Libya, Philippine Islands, South-West Africa, South Africa, and Northern Territory of Australia. The Alaska earthquake is the first for which widespread surface-water effects are known. The effects were recorded at stations on flowing streams, rivers, reservoirs, lakes, and ponds. The 755 surface-water stations recording effects are spread through 38 States, but are most numerous in the south-central and southeastern States, especially in Florida and Louisiana. Most of the fluctuations recorded can be referred to more precisely as seismic seiches; however, a few stations recorded the quake as a minor change in stage. The largest recorded seiche outside Alaska was 1.83 feet on a reservoir in Michigan. The next largest was 1.45 feet on Lake Ouachita in Arkansas. The largest fluctuation in a well was 23 feet registered by a pressure recorder near Belle Fourche, S. Dak. Fluctuations of more than 10 feet were reported from wells in Alabama, Florida, Georgia, Illinois, Missouri, and Pennsylvania. A 3.40-foot fluctuation was recorded in a well in Puerto Rico. The Alaska earthquake was registered by about seven times as many water-level recorders as recorded the Hebgen Lake, Mont., earthquake of August 19, 1959.

  19. Groundwater-level change and evaluation of simulated water levels for irrigated areas in Lahontan Valley, Churchill County, west-central Nevada, 1992 to 2012

    The acquisition and transfer of water rights to wetland areas of Lahontan Valley, Nevada, has caused concern over the potential effects on shallow aquifer water levels. In 1992, water levels in Lahontan Valley were measured to construct a water-table map of the shallow aquifer prior to the effects of water-right transfers mandated by the Fallon Paiute-Shoshone Tribal Settlement Act of 1990 (Public Law 101-618, 104 Stat. 3289). From 1992 to 2012, approximately 11,810 water-righted acres, or 34,356 acre-feet of water, were acquired and transferred to wetland areas of Lahontan Valley. This report documents changes in water levels measured during the period of water-right transfers and presents an evaluation of five groundwater-flow model scenarios that simulated water-level changes in Lahontan Valley in response to water-right transfers and a reduction in irrigation season length by 50 percent.Water levels measured in 98 wells from 2012 to 2013 were used to construct a water-table map. Water levels in 73 of the 98 wells were compared with water levels measured in 1992 and used to construct a water-level change map. Water-level changes in the 73 wells ranged from -16.2 to 4.1 feet over the 20-year period. Rises in water levels in Lahontan Valley may correspond to annual changes in available irrigation water, increased canal flows after the exceptionally dry and shortened irrigation season of 1992, and the increased conveyance of water rights transferred to Stillwater National Wildlife Refuge. Water-level declines generally occurred near the boundary of irrigated areas and may be associated with groundwater pumping, water-right transfers, and inactive surface-water storage reservoirs. The largest water-level declines were in the area near Carson Lake.Groundwater-level response to water-right transfers was evaluated by comparing simulated and observed water-level changes for periods representing water-right transfers and a shortened irrigation season in areas near Fallon and Stillwater, Nevada. In the Stillwater modeled area, water rights associated with nearly 50 percent of the irrigated land were transferred from 1992 to 1998, represented by the model scenario reduction in groundwater recharge by 50 percent. The scenario resulted in a simulated average decline of 0.6 foot; average observed water-level change for the modeled area was estimated to be 0.0 foot, or no change. In the Fallon modeled area, transfers of water rights associated with 180 acres of land occurred from 1994 to 2008. The transfer is most similar to the scenario for removal of 320 acres of irrigated land. The model scenario resulted in simulated water-level declines of 0.1; water levels measured from 1994 to 2012 indicate no significant trends in water levels, or approximately zero change in water levels, for the Fallon modeled area.The model scenarios included the simulation of a irrigation season shortened by 50 percent, which was determined to have occurred in the 1992 irrigation season in both modeled areas. The shortening of the irrigation season in the Fallon modeled area resulted in simulated water-level declines of 1.1 feet; observed declines were estimated to be 1.3 feet. The Stillwater model simulations resulted in a simulated decline of 1.4 feet, and observed water levels declined an estimated 2.3 feet for the area. The estimated difference between simulated and observed water levels are 0.2 and 0.9 foot for the Fallon and Stillwater modeled areas, respectively. Observed water-level changes were generally within one standard deviation of changes from model simulations, based on the selected periods of comparison. Simulated and observed water-level changes agree well, generally within 1 foot; however, the model scenarios were only approximately similar to the observed conditions, and periods of comparison were generally shorter for the observed periods and included additional cumulative effects of water-right transfers. Climate variability was not considered in the model scenarios.

    The home healthcare context can be unpredictable and complex, and requires registered nurses with a high level of clinical reasoning skills and professional autonomy. Thus, additional knowledge about registered nurses' clinical reasoning performance during patient home care is required. The aim of this study is to describe the cognitive processes and thinking strategies used by recently graduated registered nurses while caring for patients in home healthcare clinical practice. An exploratory qualitative think-aloud design with protocol analysis was used. Home healthcare visits to patients with stroke, diabetes, and chronic obstructive pulmonary disease in seven healthcare districts in southern Norway. A purposeful sample of eight registered nurses with one year of experience. Each nurse was interviewed using the concurrent think-aloud technique in three different patient home healthcare clinical practice visits. A total of 24 home healthcare visits occurred. Follow-up interviews were conducted with each participant. The think-aloud sessions were transcribed and analysed using three-step protocol analysis. Recently graduated registered nurses focused on both general nursing concepts and concepts specific to the domains required and tasks provided in home healthcare services as well as for different patient groups. Additionally, participants used several assertion types, cognitive processes, and thinking strategies. Our results showed that recently graduated registered nurses used both simple and complex cognitive processes involving both inductive and deductive reasoning. However, their reasoning was more reactive than proactive. The results may contribute to nursing practice in terms of developing effective nursing education programmes. Copyright © 2016 Elsevier Ltd.

    The Japan Society of Obstetrics and Gynecology (JSOG) implemented an assisted reproductive technology (ART) registry system in 1986. Here are reported the characteristics and treatment outcomes of ART cycles that were registered in 2015. JSOG has requested all participating ART facilities to register cycle-specific information for all ART cycles since 2007. A descriptive analysis was performed by using the registry database for 2015. In total, 424 151 cycles and 51 001 neonates (1 in 19.7 neonates born in Japan) were registered in 2015. The patients' mean age was 38.2 years (standard deviation = 4.5). Among the fresh cycles, 94 158 of 244 718 (38.5%) egg retrieval cycles were cycles with freeze-all embryos or oocytes, while fresh embryo transfer (ET) was performed in 70 254 cycles, signaling a decrease from 2014. There were 169 898 frozen-thawed ET cycles, resulting in 56 355 pregnancies and 40 599 neonates. Single ET was performed at a rate of 79.7% for fresh and 81.8% for frozen cycles and the singleton pregnancy/live birth rates were 96.9%/96.5% and 96.8%/96.4% for the respective cycles. The total ART cycles and live births resulting from ART has been increasing in Japan. Single ET was performed at a rate of almost 80% and ET cycles have shifted from fresh to frozen cycles.

    The increasingly closer international business cooperation in the areas of production, trade, transport and activities such as tourism and education is promoting the mobility of people. This increases the need for the provision of health care services across borders. In order to provide increasingly safer and effective treatment that is of ever higher quality in these cases as well, it is necessary to ensure that data accompanies patients even when they travel to other regions, countries or continents. eHealth solutions are one of the key tools for achieving such objectives. When building these solutions, it is necessary to take into account the different aspects and limitations brought about by the differences in the environments where such a treatment of a patient takes place. In the debates on the various types of cross-border interoperability of eHealth solutions, it is necessary to bring to attention the necessity of suitable management and interconnection of data registers that form the basis of every information system: data on patients, health care service providers and basic code tables. It is necessary to promote well-arranged and quality data in the patient's domestic environment and the best possible options for transferring and using those data in the foreign environment where the patient is receiving medical care at a particular moment. Many of the discussions dealing with conditions for the interoperability of health care information systems actually start with questions of how to ensure the interconnectivity of basic data registers.

    to compare the client satisfaction of women with uncomplicated pregnancies at the onset of labor who were transferred across care levels during childbirth and women who were not transferred across care levels in the Dutch perinatal healthcare system, and-if there are differences-to identify the variables that may explain them. the research entailed a population-based study of women with uncomplicated pregnancies at the onset of labor living in the catchment area of a Dutch Neonatal Intensive Care Unit (NICU) in the eastern part of the Netherlands who gave birth between April 2014 and September 2014. Respondents completed a validated questionnaire (n = 842; mean age 30.7 years). Client satisfaction, measured on a 10-point scale, was assessed within 12 weeks after childbirth. of the 842 respondents, 277 women experienced a transfer of care during childbirth, and 565 women were not transferred. The client satisfaction of women who were transferred across care levels (mean 8.04; SD 1.4) was significantly lower (p<0.001) than that of women who were not transferred across care levels (mean 8.78; SD 0.9). Seven variables together explained 93.2% of the difference in client satisfaction. Explanatory pregnancy and childbirth variables were perceived health problems for the mother and medical interventions during childbirth. Explanatory clients' experiences with the care process variables were respect, prompt attention, quality of basic amenities, social consideration, and choice and continuity. women were highly satisfied with the care they received, although transfers across care levels during childbirth were associated with substantially lower client satisfaction. The differences in client satisfaction between transferred and non-transferred women can largely be explained by pregnancy and childbirth characteristics, and by clients' experiences with the care process.

    Studies that assess the role of mental health for the risk of divorce are scarce and mostly rely on individual-level data, although divorce is a couple-level phenomenon. Using data on couples, we examine the effects of both spouses' psychiatric morbidity on the risk of divorce, and whether socio-demographic factors affect these associations. We followed 96,222 Finnish married couples for 6 years using register-based data on both spouses and their household. New incidence of psychiatric morbidity and subsequent divorce was identified from dates of prescription medication purchases and hospital admissions, and dates of registered divorce. Socio-demographic factors were measured annually for both spouses and their household. The effect of incident psychiatric morbidity on divorce risk was analyzed using Cox regression. Psychiatric morbidity in men increased the age-adjusted risk of divorce more than twofold and in women nearly twofold. The risk of divorce was particularly pronounced immediately after new incidence of psychiatric morbidity, before settling to a persistently high level. Psychiatric morbidity in both spouses increased the risk of divorce almost threefold. Adjustment for socio-economic factors had little effect on these associations. Psychiatric morbidity is a persistent risk factor of divorce. The risk is larger when both spouses experience psychiatric morbidity compared to only one spouse. The findings are consistent with the idea that poor relationship quality and dissatisfaction in couples suffering from mental health problems have long-term consequences for marital stability. Treatment of psychiatric morbidity should not focus only on the individual but on couple-level dynamics.

    The paper presents heat transfer research basing on a long fin with a circular cross-section. Its basis is welded to the pipe where the hot liquid paraffin, having a temperature of 70°C at the inflow, is pumped. The analyzed element is a recurrent part of a refrigeration's condenser, which is immersed in a paraffin. The temperature of the inflowing liquid is higher than the temperature of the melting process for paraffin, which allows the paraffin to liquify. The temperature at the basis of the rib changes and it is assumed that the heat transfer is quasi-stationary. On this basis the estimation of the mean value of heat transfer coefficient was conducted. The unsteady thermal field of the investigated system was registered with an infrared camera V50 produced by a Polish company Vigo System. This device is equipped with a microbolometric detector with 384 × 288 elements and the single pixel size 25 × 25 μm. Their thermal resolution is lower than 70 mK at a temperature of 30 °C. The camera operates at 7,5 ÷ 14 μm long-wave infrared radiation range. For a typical lens 35 mm the special resolution is 0.7 mrad. The result of the calculations is mean heat transfer coefficient for the considered time series. It is equal to 50 W m -2 K-1 and 47 W m -2 K-1 on the left and right side of the fin, respectively. The distance between the experimental data and the curve approximating the temperature distribution was assessed with the standard deviation, Sd = 0.04 K.

    Sharing information coherently between nodes of a quantum network is fundamental to distributed quantum information processing. In this scheme, the computation is divided into subroutines and performed on several smaller quantum registers that are connected by classical and quantum channels 1 . A direct quantum channel, which connects nodes deterministically rather than probabilistically, achieves larger entanglement rates between nodes and is advantageous for distributed fault-tolerant quantum computation 2 . Here we implement deterministic state-transfer and entanglement protocols between two superconducting qubits fabricated on separate chips. Superconducting circuits 3 constitute a universal quantum node 4 that is capable of sending, receiving, storing and processing quantum information 5-8 . Our implementation is based on an all-microwave cavity-assisted Raman process 9 , which entangles or transfers the qubit state of a transmon-type artificial atom 10 with a time-symmetric itinerant single photon. We transfer qubit states by absorbing these itinerant photons at the receiving node, with a probability of 98.1 ± 0.1 per cent, achieving a transfer-process fidelity of 80.02 ± 0.07 per cent for a protocol duration of only 180 nanoseconds. We also prepare remote entanglement on demand with a fidelity as high as 78.9 ± 0.1 per cent at a rate of 50 kilohertz. Our results are in excellent agreement with numerical simulations based on a master-equation description of the system. This deterministic protocol has the potential to be used for quantum computing distributed across different nodes of a cryogenic network.

    Survey data from 395 high school students revealed that girls perceive more privacy risks and have a higher level of privacy concerns than boys. Regarding privacy protection behaviors, boys tended to read unsolicited e-mail and register for Web sites while directly sending complaints in response to unsolicited e-mail. This study found girls to provide inaccurate information as their privacy concerns increased. Boys, however, refrained from registering to Web sites as their concerns increased.

    to verify the data quality of childbirth registers and explore factors that influence quality at two rural district hospitals in Western Kenya. a retrospective comparative case study for data quality of the 2006 childbirth registers by quantitative and qualitative methods. Siaya and Bondo District Hospitals. after confirming the physical condition and availability of childbirth registers, the total number of births; number of complete/incomplete data; and number of complete data that were illegible, incorrectly coded, inappropriate and unrecognised were verified quantitatively to evaluate accuracy and completeness. Data categories and instructions were examined qualitatively to assess the relevance, completeness and accuracy of the data. Semi-structured interviews were conducted with key informants to capture their views and factors that influence data quality. the childbirth registers used by the two hospitals were not developed by the Ministry of Health, and their supply to Bondo was interrupted. Of the 30 data categories in the registers, five for Siaya and 23 for Bondo were more than 20% incomplete. Data for number of antenatal consultations and use of human immunodeficiency virus drugs were at least 50% incomplete for both hospitals. The percentage of illegible, incorrectly coded and inappropriate data was relatively low, and only the place of residence had unrecognised data. Data categories in the registers did not correspond well with those of monthly reports, and inappropriate instructions suggested hidden inaccuracy among apparently valid data. Organisational impediments of the health information system in general, perinatal and intrapartum contexts were identified. data quality of the childbirth registers was unsatisfactory. Influential factors were primarily organisational and technical, which may have had an adverse effect on midwives' record keeping behaviour. data quality of the registers can be improved by re-examining technical challenges and organisational impediments at different levels. Midwives' awareness of data quality needs to be increased by sharing the purpose of the childbirth registers. Strong political commitment is also indispensable for putting these findings into action.

  9. I. Measuring and Reducing Stress and Surface Roughness in IBAD MgO Films and II. Developing Tools to Measure Transfer in Undergraduate Chemistry Students

    NASA Astrophysics Data System (ADS)

    Antonakos, Cory Dale

    I. MgO may be grown with a biaxial texture onto an amorphous substrate with the use of ion beam assisted deposition (IBAD). This MgO film may then be used as a platform on which to grow epitaxial films on an amorphous membrane for characterization purposes. However, the IBAD MgO film is stressed, causing buckles in the amorphous membrane and problems with further film growth on the IBAD MgO. This dissertation work explores the source of this film stress and develops methods to relax the stress and reduce surface roughness with annealing and increased growth temperature. It is determined that annealing and increased growth temperature coupled with a higher ion-to-atom ratio (IAR) during film growth reduce stress and surface roughness sufficiently to use even thinner IBAD MgO films as an intermediate layer between an amorphous membrane and epitaxial film. II. Much of the existing literature on knowledge transfer concludes that transfer is rare and does not occur spontaneously. However, studies supporting that transfer is rare often use methods that focus on binary success or failure to solve a problem correctly and do not analyze thought process. This dissertation work aims at developing transfer questions that allow open-ended responses, developing a method of analysis for these responses that looks for transfer in the problem-solving process, and assessing the methodology itself and its sensitivity, validity, and utility as a general transfer measurement technique for use across a broad range of expertise levels in chemistry. Detailed analysis of responses to each transfer question show that some transfer questions are more effective at distinguishing between expertise levels while also allowing responders of all levels to show knowledge transfer. Simpler questions that are more accessible to students of introductory chemistry proved the most useful at eliciting a range of responses that correlate with expertise level while still showing some degree of transfer in all levels of responders. More challenging questions with complex systems and common misconceptions are too advanced for lower level undergraduates to show knowledge transfer, but may be useful to show transfer in advanced undergraduates and experts.

    OBJECTIVES: To assess the feasibility of setting up a register of patients with asplenia within a defined geographical area; to ensure that guidelines on best practice were implemented; to obtain information on antibody levels to pneumococcal capsular polysaccharides and Haemophilus influenzae type b capsular polysaccharide, before and after immunisation and annually thereafter; to raise awareness of risks among clinicians and to offer advice on management. DESIGN: Prospective recruitment using multiple sources of recruitment. Annual follow up reminders sent from Registration Centre. SUBJECTS: Population of (old, pre-1995) Northern Health Region: approximately 3.1 million. MAIN OUTCOME MEASURES: Data were obtained on reasons for asplenia, duration of asplenia, use of prophylactic antibiotics, Medic-Alert bracelets, immunisations, antibody levels, death. RESULTS: The register was initiated at the beginning of April 1995 and ran to the end of March 1997. After two years of operation, 1111 cases had been registered but the response from some health districts was poor. Major primary causes of asplenia were trauma (264), other surgical (198), lymphoproliferative disease (154), and idiopathic thrombocytopenic purpura (147). There were 664 patients on prophylactic antibiotics, of whom 498 were on continuous antibiotics. Only 18 had any type of warning bracelet. Antibody measurements were carried out at least once on 75% of patients; 306 patients had satisfactory antibody levels on first blood sample in year 1, rising to 405 in year 2; 43 patients failed to make any antibody response to Pneumovax despite multiple immunisations, and three patients failed to respond to Hib vaccine. Sixteen patients with satisfactory antibody levels in year 1 had low levels in year 2 requiring vaccine boosters. Sixteen deaths were reported, two of which were directly attributable to overwhelming sepsis. CONCLUSIONS: Registration has been successful and has raised awareness of the management of asplenia. Compliance with antibiotic prophylaxis and immunisation was initially poor. A potential high risk group of vaccine non-responders has been identified and poor persistence of pneumococcal antibodies has been identified which is likely to alter approaches to immunisation in asplenic patients.

  11. Stagnation Region Heat Transfer Augmentation at Very High Turbulence Levels

    DOE Office of Scientific and Technical Information (OSTI.GOV)

    Ames, Forrest; Kingery, Joseph E.

    A database for stagnation region heat transfer has been extended to include heat transfer measurements acquired downstream from a new high intensity turbulence generator. This work was motivated by gas turbine industry heat transfer designers who deal with heat transfer environments with increasing Reynolds numbers and very high turbulence levels. The new mock aero-combustor turbulence generator produces turbulence levels which average 17.4%, which is 37% higher than the older turbulence generator. The increased level of turbulence is caused by the reduced contraction ratio from the liner to the exit. Heat transfer measurements were acquired on two large cylindrical leading edgemore » test surfaces having a four to one range in leading edge diameter (40.64 cm and 10.16 cm). Gandvarapu and Ames [1] previously acquired heat transfer measurements for six turbulence conditions including three grid conditions, two lower turbulence aero-combustor conditions, and a low turbulence condition. The data are documented and tabulated for an eight to one range in Reynolds numbers for each test surface with Reynolds numbers ranging from 62,500 to 500,000 for the large leading edge and 15,625 to 125,000 for the smaller leading edge. The data show augmentation levels of up to 136% in the stagnation region for the large leading edge. This heat transfer rate is an increase over the previous aero-combustor turbulence generator which had augmentation levels up to 110%. Note, the rate of increase in heat transfer augmentation decreases for the large cylindrical leading edge inferring only a limited level of turbulence intensification in the stagnation region. The smaller cylindrical leading edge shows more consistency with earlier stagnation region heat transfer results correlated on the TRL (Turbulence, Reynolds number, Length scale) parameter. The downstream regions of both test surfaces continue to accelerate the flow but at a much lower rate than the leading edge. Bypass transition occurs in these regions providing a useful set of data to ground the prediction of transition onset and length over a wide range of Reynolds numbers and turbulence intensity and scales.« less

    Increased demand in internet of thing (IOT) application based has inadvertently forced the move towards higher complexity of integrated circuit supporting SoC. Such spontaneous increased in complexity poses unequivocal complicated validation strategies. Hence, the complexity allows researchers to come out with various exceptional methodologies in order to overcome this problem. This in essence brings about the discovery of dynamic verification, formal verification and hybrid techniques. In reserve, it is very important to discover bugs at infancy of verification process in (SoC) in order to reduce time consuming and fast time to market for the system. Ergo, in this paper we are focusing on the methodology of verification that can be done at Register Transfer Level of SoC based on the AMBA bus design. On top of that, the discovery of others verification method called Open Verification Methodology (OVM) brings out an easier way in RTL validation methodology neither as the replacement for the traditional method yet as an effort for fast time to market for the system. Thus, the method called OVM is proposed in this paper as the verification method for larger design to avert the disclosure of the bottleneck in validation platform.

    We demonstrate ultrafast soliton-based nonlinear balancing of dual-core asymmetry in highly nonlinear photonic crystal fiber at sub-nanojoule pulse energy level. The effect of fiber asymmetry was studied experimentally by selective excitation and monitoring of individual fiber cores at different wavelengths between 1500 nm and 1800 nm. Higher energy transfer rate to non-excited core was observed in the case of fast core excitation due to nonlinear asymmetry balancing of temporal solitons, which was confirmed by the dedicated numerical simulations based on the coupled generalized nonlinear Schrödinger equations. Moreover, the simulation results correspond qualitatively with the experimentally acquired dependences of the output dual-core extinction ratio on excitation energy and wavelength. In the case of 1800 nm fast core excitation, narrow band spectral intensity switching between the output channels was registered with contrast of 23 dB. The switching was achieved by the change of the excitation pulse energy in sub-nanojoule region. The performed detailed analysis of the nonlinear balancing of dual-core asymmetry in solitonic propagation regime opens new perspectives for the development of ultrafast nonlinear all-optical switching devices.

    The carbon ion (C-ion) beams provide unique advantageous biological and physical properties in radiotherapy (RT) for malignant tumors. C-ion beams have a high relative biological effectiveness (RBE) resulting from the high linear energy transfer (LET). In terms of their physical characteristics, C-ion beams exhibit a spread-out Bragg peak (SOBP) and make for a better dose distribution of the target volume by specified beam modulations. Between June 1994 and August 2005, a total of 2,371 patients with malignant tumors were registered in phase I/II dose-escalation studies and clinical phase II trials using C-ion beams generated at Heavy Ion Medical Accelerator in Chiba (HIMAC). In the initial dose-escalation studies, grade 3 or more late rectal complications had developed in some patients. However, the adverse effects were resolved because of the use of appropriate dose levels and modification of the radiation technique. C-ion beams can carry out hypofractionated radiotherapy with a large fraction dose and reduce the overall treatment times compared with conventional radiotherapy. They can also achieve better local tumor control even for radio-resistant tumors such as malignant melanoma, hepatocellular carcinoma and bone and soft tissue sarcomas with minimal morbidity to the normal surrounding tissues.

    To explore registered nurses' experiences of medication errors and patient safety in home care. The focus of care for older patients has shifted from institutional care towards a model of home care. Medication errors are common in this situation and can result in patient morbidity and mortality. An exploratory qualitative design with focus group interviews was used. Four focus group interviews were conducted with 20 registered nurses in home care. The data were analysed using content analysis. Five categories were identified as follows: lack of information, lack of competence, reporting medication errors, trade name products vs. generic name products, and improving routines. Medication errors occur frequently in home care and can threaten the safety of patients. Insufficient exchange of information and poor communication between the specialist and home-care health services, and between general practitioners and healthcare workers can lead to medication errors. A lack of competence in healthcare workers can also lead to medication errors. To prevent these, it is important that there should be up-to-date information and communication between healthcare workers during the transfer of patients from specialist to home care. Ensuring competence among healthcare workers with regard to medication is also important. In addition, there should be openness and accurate reporting of medication errors, as well as in setting routines for the preparation, alteration and administration of medicines. To prevent medication errors in home care, up-to-date information and communication between healthcare workers is important when patients are transferred from specialist to home care. It is also important to ensure adequate competence with regard to medication, and that there should be openness when medication errors occur, as well as in setting routines for the preparation, alteration and administration of medications. © 2017 John Wiley & Sons Ltd.

    Nursing education has a history of encouraging students to know their patients and to negotiate the in-between of art/science, person/profession, and intuition/evidence. Nurse-teachers know that students may abandon some values and practices when they encounter practice environments that are complex and have competing agendas. We are concerned that nursing knowledge is black-boxed, invisible and taken-for-granted, in healthcare settings. Our research explores how nursing students and nurses are constructing and enacting person-centred care in mental health education and practice. We want to understand the nursing standpoint on this significant ontological issue and to make nursing knowledge construction and utilization visible; illuminating how person-centred theory emerges from practice. The process involved four 3-hour group meetings and an individual follow-up telephone conversation. Students and nurses met at a tertiary-care mental health organization. Fourteen nurses (Registered Nurses and Registered Practical Nurses) and nursing students (Bachelor of Science in Nursing and Practical Nursing) participated in our inquiry. We used arts-informed narrative inquiry to explore experience through the arts such as metaphor, collage, poems, letters, and group conversations. The black-box is opened as the inquiry reveals how nursing knowledge is constructed, assumptions are challenged and new practices emerge. Our research is significant for education and for practice and is transferable to other populations and settings. Nurses are affirmed in person-centred values and practices that include partnership with those in their care, role modeling for colleagues and mentoring students and new nurses. Students participate in transferring their learning from school to practice, in the company of experienced colleagues; together they open the black-box to show how nurses conceptualize and enact person-centred care.

    Rosetta, part of ESA's Horizon 2000 programme, will orbit and land on the comet 67P/Churyumov-Gerasimenko in May 2014. However, launched in March 2004, its trajectory has thus far muchly consisted of a series of planetary fly-bys and gravitational assists using Mars (2007) and Earth (March 2005, 2007 and 2009). During these close fly-bys Rosetta captured measurements of these planets - and of particular interest are those registed by the Visual Infrared Thermal Imaging Spectrometer VIRTIS of Earth, which were taken to help calibrate VIRTIS. Rosetta/VIRTIS measures at high spectral resolution from 0.25 - 5.0 microns, a spectral range which has been well studied by Earth observing instruments such as Meteosat Second Generation Spinning Enhanced Visible and Infrared Imager (MSG/SEVIRI) and the Advanced Along-Track Scanning Radiometer (AATSR). Earth observing instruments, whilst having superior spatio-temporal coverage to the data provided during the Rosetta/VIRTIS fly-bys, are typically constrained to measuring in only a few spectral channels. Hence, Rosetta/VIRTIS should yield more detailed spectral information than these instruments - and is a good candidate for intercomparison studies. To this end, the radiative transfer software NEMESIS (Irwin et al., 2009) is employed for the first time on Earth simulations, having been used extensively for other bodies such as Venus, Mars, Jupiter, Saturn, Neptune, Uranus and Titan. This work compares Rosetta/VIRTIS measurements with NEMESIS-simulated spectra, concentrating on quantifying the ability of NEMESIS to reproduce spectral features associated with different surface topographies (such as ocean, desert and vegetation) in combination with clear and cloudy atmospheric states. Preliminary estimations of temperature and trace-species concentrations and distributions are presented as sample products.

    Rosetta, the Solar System cornerstone mission of ESA's Horizon 2000 programme, consists of an orbiter and a lander, and is due to arrive at the comet 67P/Churyumov-Gerasimenko in May 2014. Following its 2004 launch, Rosetta carried out a series of planetary fly-bys and gravitational assists. On these close fly-bys of the Earth, measurements were taken by the Visible Infrared Thermal Imaging Spectrometer (VIRTIS). Analysis of these spectra and comparison with spectra acquired by Earth-observing satellites can support the verification of the inflight calibration of Rosetta/VIRTIS. In this paper, measurements taken by VIRTIS in November 2009 are compared with suitable coincident data from Earth-observing instruments (ESA-ENVISAT/AATSR and SCIAMACHY, and EOS-TERRA/MODIS). Radiative transfer simulations using NEMESIS (Irwin et al., 2008) are fit to the fly-by data taken by VIRTIS, using representative atmospheric and surface parameters. VIRTIS measurements correlate 90% with AATSR's, 85-94% with MODIS, and 82-88% with SCIAMACHYs. The VIRTIS spectra are reproducible in the 1-5 μm region, except in the 1.4 μm deep water vapour spectral absorption band in the near-infrared in cases in which the radiance is very low (cloud-free topographies), where VIRTIS consistently registers more radiance than do MODIS and SCIAMACHY. Over these cloud-free regions, VIRTIS registers radiances a factor of 3-10 larger than SCIAMACHY and of 3-8 greater than MODIS. It is speculated that this discrepancy could be due to a spectral light leak originating from reflections from the order-sorting filters above the detector around 1.4 μm.

    It is becoming accepted that ultrathin dielectric layers on metals are not merely passive decoupling layers, but can actively influence orbital energy level alignment and charge transfer at interfaces. As such, they can be important in applications ranging from catalysis to organic electronics. However, the details at the molecular level are still under debate. In this study, we present a comprehensive analysis of the phenomenon of charge transfer promoted by a dielectric interlayer with a comparative study of pentacene adsorbed on Ag(001) with and without an ultrathin MgO interlayer. Using scanning tunneling microscopy and photoemission tomography supported by density functional theory, we are able to identify the orbitals involved and quantify the degree of charge transfer in both cases. Fractional charge transfer occurs for pentacene adsorbed on Ag(001), while the presence of the ultrathin MgO interlayer promotes integer charge transfer with the lowest unoccupied molecular orbital transforming into a singly occupied and singly unoccupied state separated by a large gap around the Fermi energy. Our experimental approach allows a direct access to the individual factors governing the energy level alignment and charge-transfer processes for molecular adsorbates on inorganic substrates.

    Researchers and educators raise the question of whether pupils' academic performance can be improved through parental involvement in academic activities. The main objective of the following study is to verify whether parental involvement in school activities and family socioeconomic status are associated with children's academic achievement. 150 Spanish seventh grade pupils completed intelligence tests, and their teachers assessed parents' involvement in the school and estimated parents' cultural levels. To measure academic achievement the pupil's overall grade was taken from the Pupils' Final Evaluation Registers. The education and professional level of the mother and father and home size were obtained from the Pupil Personal Register; these variables define the family socioeconomic status. The data, analyzed through application of structural equations, suggest that academic achievement is directly influenced by the cultural level of the family and the child's intelligence but is indirectly influenced by parental involvement in school activities and the socioeconomic status of the child's family.

    Researchers have demonstrated repeatedly the importance of the relationship linking job satisfaction to employee retention. In rural areas of the country, where a persistent maldistribution of nurses continues to hamper health care delivery, the potential benefits of bolstering retention via enhancements in job satisfaction are of utmost utility to administrators and providers alike. Data were gathered from a multistate survey of registered nurses (RNs) practicing in rural hospitals, skilled nursing facilities, and community/public health settings (N = 1,647; response rate = 40.3%). The investigators found that the use of tuition reimbursement corresponded significantly with increased levels of job satisfaction among nurses in all three practice environments, as did day care services for nurses in acute care settings. Also, among hospital-based RNs, level of nursing education was found to be a significant factor in the relationship between tuition reimbursement and job satisfaction, with the highest level occurring among diploma-prepared nurses.

    Background and purpose Hip displacement is common in children with severe cerebral palsy (CP) and can cause problems such as pain, contractures, and nursing difficulties. Caregiver priorities and child health index of life with disabilities (CPCHILD) is a recently developed measure of health-related quality of life (HRQL) in children with severe CP. The associations between CPCHILD scores and hip displacement have not been investigated. We explored the effect of hip displacement on HRQL. Patients and methods 67 children were recruited from the population-based Norwegian CP register. Mean age was 9 (7–12) years. There were 40 boys. Gross motor function classification system (GMFCS) distribution was 12 level III, 17 level IV, and 38 level V. Hip displacement was assessed by radiographic migration percentage (MP). The criterion for hip displacement was MP of the worst hip of ≥40%. Primary caregivers responded to 5 of the 6 domains of the CPCHILD questionnaire. Results Hip displacement was found in 18 children and it was significantly associated with lower scores on the CPCHILD domains 3 (Comfort and Emotions) and 5 (Health), but not with domains 1 (Activities of Daily Living/Personal Care), 2 (Positioning, Transfer, and Mobility), and 6 (Overall Quality of Life). GMFCS level V was a significant predictor of low scores in all the domains. Interpretation For the assessment of HRQL in children with severe CP and hip problems, we propose a modified and simplified version of the CPCHILD consisting of 14 of 37 questions. This would reduce the responders’ burden and probably increase the response rate in clinical studies without losing important information. PMID:27892753

    Multilevel synchrotron radiation-based microtomography has been performed on a human jaw segment obtained at autopsy by cutting increasingly smaller samples from the original segment. The focus of this study lay on the microstructure of the interface between root, periodontal ligament (PDL) and alveolar bone in order to find an answer to the question why alveolar bone remodels during orthodontic loading, when the associated stress and strain levels calculated with finite element analyses are well below the established threshold levels for bone remodeling. While the inner surface of the alveolus appears to be rather smooth on the lower resolution scans, detailed scans of the root-PDL-bone interface reveal that on a microscopical scale it is actually quite rough and uneven with bony spiculae protruding into the PDL space. Any external (orthodontic) loading applied to the root, when transferred through the PDL to the alveolar bone, will cause stress concentrations in these spiculae, rather than be distributed over a "smooth surface". As osteocyte lacunae are shown to be present in these spiculae, the local amplified stresses and strain can well be registered by the mechano-sensory network of osteocytes. In addition, a second stress amplification mechanism, due to the very presence of the lacunae themselves, is evidence that stresses and strains calculated with FE analyses, based on macroscopical scale models of teeth and their supporting structures, grossly underestimate the actual mechanical loading of alveolar bone at tissue level. It is therefore hypothesized that remodeling of alveolar bone is subject to the same biological regulatory process as remodeling in other bones. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Cross-species transferability is a quick and economic method to enrich SSR database, particularly for minor crops where little genomic information is available. However, transferability of SSR markers varies greatly between species, genera and families of plant species. We assessed confamiliar transferability of SSR markers from cotton (Gossypium hirsutum) and jute (Corchorus olitorius) to 22 species distributed in different taxonomic groups of Malvaceae. All the species selected were potential industrial crop species having little or no genomic resources or SSR database. Of the 14 cotton SSR loci tested, 13 (92.86 %) amplified in G. arboreum and 71.43 % exhibited cross-genera transferability. Nine out of 11 jute SSRs (81.81 %) showed cross-transferability across genera. SSRs from both the species exhibited high polymorphism and resolving power in other species. The correlation between transferability of cotton and jute SSRs were highly significant (r = 0.813). The difference in transferability among species was also significant for both the marker groups. High transferability was observed at genus, tribe and subfamily level. At tribe level, transferability of jute SSRs (41.04 %) was higher than that of cotton SSRs (33.74 %). The tribe Byttnerieae exhibited highest SSR transferability (48.7 %). The high level of cross-genera transferability (>50 %) in ten species of Malvaceae, where no SSR resource is available, calls for large scale transferability testing from the enriched SSR databases of cotton and jute.

    Using stimulated Raman adiabatic passage (SARP), it is possible, in principle, to transfer all the population in a rovibrational level of an isolated diatomic molecule to an excited rovibrational level. We use an overlapping sequence of pump (532 nm) and dump (683 nm) single-mode laser pulses of unequal fluence to prepare isolated H2 molecules in a molecular beam. In a first series of experiments we were able to transfer more than half the population to an excited rovibrational level [N. Mukherjee, W. R. Dong, J. A. Harrison, and R. N. Zare, J. Chem. Phys. 138(5), 051101-1-051101-4 (2013)]. Since then, we have achieved almost complete transfer (97% ± 7%) of population from the H2 (v = 0, J = 0) ground rovibrational level to the H2 (v = 1, J = 0) excited rovibrational level. An explanation is presented of the SARP process and how these results are obtained.

    2006-01-01

    This report provides a user guide for the Compressible Flow Toolbox, a collection of algorithms that solve almost 300 linear and nonlinear classical compressible flow relations. The algorithms, implemented in the popular MATLAB programming language, are useful for analysis of one-dimensional steady flow with constant entropy, friction, heat transfer, or shock discontinuities. The solutions do not include any gas dissociative effects. The toolbox also contains functions for comparing and validating the equation-solving algorithms against solutions previously published in the open literature. The classical equations solved by the Compressible Flow Toolbox are: isentropic-flow equations, Fanno flow equations (pertaining to flow of an ideal gas in a pipe with friction), Rayleigh flow equations (pertaining to frictionless flow of an ideal gas, with heat transfer, in a pipe of constant cross section.), normal-shock equations, oblique-shock equations, and Prandtl-Meyer expansion equations. At the time this report was published, the Compressible Flow Toolbox was available without cost from the NASA Software Repository.

    Improvement in prosthetic training using intermanual transfer (the transfer of motor skills from the trained, “unaffected” hand to the untrained, “affected” hand) has been shown in previous studies. The aim of this study is to determine the influence of the inter-training interval on the magnitude of the intermanual transfer effects. This was done using a mechanistic, randomized, single-blinded pretest-posttest design. Sixty-four able-bodied, right-handed participants were randomly assigned to the Short and Long Interval Training Groups and the Short and Long Interval Control Groups. The Short and Long Interval Training Groups used a prosthesis simulator in their training program. The Short and Long Interval Control Groups executed a sham training program, that is, a dummy training program in which the same muscles were trained as with the prosthesis simulator. The Short Interval Training Group and the Short Interval Control Groups trained on consecutive days, while the Long Interval Training Group and Long Interval Control Group trained twice a week. To determine the improvement in skills, a test was administered before, immediately after, and at two points in time after the training. Training was performed with the “unaffected” arm; tests were performed with the “affected” arm. The outcome measurements were: the movement time (the time from the beginning of the movement until completion of the task); the duration of maximum hand opening, (the opening of the prosthetic hand while grasping an object); and the grip-force control (the error from the required grip-force during a tracking task). Intermanual transfer was found in movement times, but not in hand opening or grip-force control. The length of the inter-training interval did not affect the magnitude of intermanual transfer effects. No difference in the intermanual transfer effect in upper-limb prosthesis training was found for training on a daily basis as compared to training twice a week. Nederlands Trial Register NTR3888.

    What motivates family members to share resources? Past research argues for, on the one hand, love and altruism, and on the other, the expectation of reciprocity. Drawing on this literature, this paper examines intergenerational transfers between small farmers and their non-coresident children in the rural area around the city of Altamira, Pará, Brazil. We apply GoM (Grade of Membership) models to create profiles of private transfers, using data collected in 2005 by a team from Indiana University. The results show three profiles: low intergenerational transfers, high levels of transfers of visits and help, and high levels of transfers of visits and money. There is no clear difference in profile by birth order, but we do find sex differences in profile. Men are more likely to send money while women provide time transfers (work and visits). Upward transfers are most common from children with high levels of education or living in urban areas, suggesting a repayment of prior investments made by parents. Thus, our empirical evidence supports theories arguing that transfers are motivated by intertemporal contracts between parents and children, and that altruistic theories of family transfers should be rethought among rural agricultural populations in contexts characterized by many environmental and institutional challenges.

    This study examined the relationship between the level of trust with immediate supervisor and the level of intent to stay at work among registered nurses (RNs) in Jordan and explored if there is a significant difference between RNs working in governmental- and university-affiliated teaching hospitals. Financial retention strategies are not feasible in low- and middle-income countries. This study investigated if the level of trust that RNs hold toward their immediate supervisors could affect their intent to stay at work, so as to be used as a nonfinancial strategy. A descriptive correlational design was used to examine this relationship among a convenience sample of 260 hospital nurses in Jordan. Descriptive and inferential statistics were used to analyze the data. When the level of trust increased, the level of intent to stay at work also increased. RNs working in governmental-affiliated teaching hospitals reported higher levels of trust and intent to stay at work than those working in university-affiliated teaching hospitals. The findings emphasized the positive effect of trust with immediate supervisor on the level of RNs' intent to stay. Building trust between RNs and their immediate supervisors could be an important retention strategy. © 2016 Wiley Periodicals, Inc.

  12. Prospective register-based study of the impact of immigration on educational inequalities in mortality in Norway.

    Differences in mortality with regard to socioeconomic status have widened in recent decades in many European countries, including Norway. A rapid upsurge of immigration to Norway has occurred since the 1990s. The article investigates the impact of immigration on educational mortality differences among adults in Norway. Two linked register-based data sets are analyzed; the first consists of all registered inhabitants aged 20-69 in Norway January 1, 1993 (2.6 millions), and the second of all registered inhabitants aged 20-69 as of January 1, 2008 (2.8 millions). Deaths 1993-1996 and 2008-2011, respectively, immigrant status, and other background information are available in the data. Mortality is examined by Cox regression analyses and by estimations of age-adjusted deaths per 100,000 personyears. Both relative and absolute educational inequality in mortality increased from the 1993-1996 period to 2008-2011, but overall mortality levels went down during these years. Immigrants in general, and almost all the analyzed immigrant subcategories, had lower mortality than the native majority. This was due to comparatively low mortality among lower educated immigrants, while mortality among higher educated immigrants was similar to the mortality level of highly educated natives. The widening of educational inequality in mortality during the 1990s and 2000s in Norway was not due to immigration. Immigration rather contributed to slightly lower overall mortality in the population and a less steep educational gradient in mortality.

  13. Probing resonant energy transfer in collisions of ammonia with Rydberg helium atoms by microwave spectroscopy

    Zhelyazkova, V.; Hogan, S. D.

    2017-12-01

    We present the results of experiments demonstrating the spectroscopic detection of Förster resonance energy transfer from NH3 in the X1A1 ground electronic state to helium atoms in 1sns 3S1 Rydberg levels, where n = 37 and n = 40. For these values of n, the 1sns 3S1 → 1snp 3PJ transitions in helium lie close to resonance with the ground-state inversion transitions in NH3 and can be tuned through resonance using electric fields of less than 10 V/cm. In the experiments, energy transfer was detected by direct state-selective electric field ionization of the 3S1 and 3PJ Rydberg levels and by monitoring the population of the 3DJ levels following pulsed microwave transfer from the 3PJ levels. Detection by microwave spectroscopic methods represents a highly state selective, low-background approach to probing the collisional energy transfer process and the environment in which the atom-molecule interactions occur. The experimentally observed electric-field dependence of the resonant energy transfer process, probed both by direct electric field ionization and by microwave transfer, agrees well with the results of calculations performed using a simple theoretical model of the energy transfer process. For measurements performed in zero electric field with atoms prepared in the 1s40s 3S1 level, the transition from a regime in which a single energy transfer channel can be isolated for detection to one in which multiple collision channels begin to play a role has been identified as the NH3 density was increased.

  14. An integrated reweighting theory of perceptual learning

    Improvements in performance on visual tasks due to practice are often specific to a retinal position or stimulus feature. Many researchers suggest that specific perceptual learning alters selective retinotopic representations in early visual analysis. However, transfer is almost always practically advantageous, and it does occur. If perceptual learning alters location-specific representations, how does it transfer to new locations? An integrated reweighting theory explains transfer over retinal locations by incorporating higher level location-independent representations into a multilevel learning system. Location transfer is mediated through location-independent representations, whereas stimulus feature transfer is determined by stimulus similarity at both location-specific and location-independent levels. Transfer to new locations/positions differs fundamentally from transfer to new stimuli. After substantial initial training on an orientation discrimination task, switches to a new location or position are compared with switches to new orientations in the same position, or switches of both. Position switches led to the highest degree of transfer, whereas orientation switches led to the highest levels of specificity. A computational model of integrated reweighting is developed and tested that incorporates the details of the stimuli and the experiment. Transfer to an identical orientation task in a new position is mediated via more broadly tuned location-invariant representations, whereas changing orientation in the same position invokes interference or independent learning of the new orientations at both levels, reflecting stimulus dissimilarity. Consistent with single-cell recording studies, perceptual learning alters the weighting of both early and midlevel representations of the visual system. PMID:23898204

    This research was undertaken to understand the influence of registered nurses on nursing students' learning in the clinical environment to inform strategies to enable registered nurses to provide effective support to learners while also assisting nursing students to adopt approaches to maximise their learning in the clinical environment. A case study approach was applied in this research to explore descriptions of clinical experience of five final year nursing students. The student participants identified the importance of the clinical environment to their learning and wanted to and had actively managed their learning in the clinical environment. The students did not passively acquire knowledge or simply replicate what they observed from others. There was evidence that the students had strong and established perceptions of what constituted 'good' nursing and described an ability to discriminate between differing levels of nursing practice. Nursing knowledge was gained from respected registered nurses who were best able to describe and demonstrate the 'tricks of the trade' and 'little things that matter' when providing 'good' nursing. The outcomes from this research indicate an important role for registered nurses in both shaping nursing students' professional nursing identity and access to clinical learning.

    2006-11-01

    It is the position of the American Dietetic Association (ADA) that primary prevention is the most effective, affordable course of action for preventing and reducing risk for chronic disease. Registered dietitians and dietetic technicians, registered, are leaders in delivering preventive services in both clinical and community settings, including advocating for funding and inclusion of these services in programs and policy initiatives at local, state, and federal levels. In addition, registered dietitians are leaders in facilitating and participating in research in chronic disease prevention and health promotion. Diet, nutrition, and physical activity are important factors in the promotion and maintenance of good health throughout the life cycle. Cost-effective interventions that produce a change in personal health practices are likely to lead to substantial reductions in the incidence and severity of the leading causes of disease in the United States. In an era of increasing health care expenditures and relative decreases in availability of federal funds, there is increasing demand on health promotion and disease prevention to be economically viable. Through clinical involvement and rigorous participation in research on chronic disease prevention and health promotion, the field of dietetics can lead the way to effectively translate the impact of nutrition on all ages.

    In recent years, the use of large data sets, such as electronic health records, has increased. These large data sets are often referred to as "Big Data," which have various definitions. The purpose of this article was to summarize and review the utilization, strengths, and challenges of register data, which means a written record containing regular entries of items or details, and Big Data, especially in maternal nursing, using 4 examples of studies from the Finnish Medical Birth Register data and relate these to other international databases and data sets. Using large health register data is crucial when studying and understanding outcomes of maternity care. This type of data enables comparisons on a population level and can be utilized in research related to maternal health, with important issues and implications for future research and clinical practice. Although there are challenges connected with register data and Big Data, these large data sets offer the opportunity for timely insight into population-based information on relevant research topics in maternal health. Nurse researchers need to understand the possibilities and limitations of using existing register data in maternity research. Maternal child nurse researchers can be leaders of the movement to utilize Big Data to improve global maternal health.

    To develop a formula for allocating resources for commissioning hospital care to all general practices in England based on the health needs of the people registered in each practice Multivariate prospective statistical models were developed in which routinely collected electronic information from 2005-6 and 2006-7 on individuals and the areas in which they lived was used to predict their costs of hospital care in the next year, 2007-8. Data on individuals included all diagnoses recorded at any inpatient admission. Models were developed on a random sample of 5 million people and validated on a second random sample of 5 million people and a third sample of 5 million people drawn from a random sample of practices. All general practices in England as of 1 April 2007. All NHS inpatient admissions and outpatient attendances for individuals registered with a general practice on that date. All individuals registered with a general practice in England at 1 April 2007. Power of the statistical models to predict the costs of the individual patient or each practice's registered population for 2007-8 tested with a range of metrics (R(2) reported here). Comparisons of predicted costs in 2007-8 with actual costs incurred in the same year were calculated by individual and by practice. Models including person level information (age, sex, and ICD-10 codes diagnostic recorded) and a range of area level information (such as socioeconomic deprivation and supply of health facilities) were most predictive of costs. After accounting for person level variables, area level variables added little explanatory power. The best models for resource allocation could predict upwards of 77% of the variation in costs at practice level, and about 12% at the person level. With these models, the predicted costs of about a third of practices would exceed or undershoot the actual costs by 10% or more. Smaller practices were more likely to be in these groups. A model was developed that performed well by international standards, and could be used for allocations to practices for commissioning. The best formulas, however, could predict only about 12% of the variation in next year's costs of most inpatient and outpatient NHS care for each individual. Person-based diagnostic data significantly added to the predictive power of the models.

    To assess revision rates after knee arthroplasty by comparing the cumulative results from worldwide clinical studies and arthroplasty registers. We hypothesised that the revision rate of all clinical studies of a given implant and register data would not differ significantly. A systematic review of clinical studies in indexed peer-reviewed journals was performed followed by internal and external validation. Parameters for measurement of revision were applied (Revision for any reason, Revisions per 100 observed component years). Register data served as control group. Thirty-six knee arthroplasty systems were identified to meet the inclusion criteria: 21 total knee arthroplasty (TKA) systems, 14 unicondylar knee arthroplasty (UKA) systems, one patello-femoral implant system. For 13 systems (36%), no published study was available that contained revision data. For 17 implants (47%), publications were available dealing with radiographic, surgical or technical details, but power was too weak to compare revision rates at a significant level. Six implant systems (17%) had a significant number of revisions published and were finally analysed. In general, developers report better results than independent users. Studies from developers represent an overproportional share of all observed component years. Register data report overall 10-year revision rates of TKA of 6.2% (range: 4.9-7.8%), rates for UKA are 16.5% (range: 9.7-19.6%). Revision rates of all clinical studies of a given implant do not differ significantly from register data. However, significant differences were found between the revision rates published by developers and register data. Therefore the different data need to be interpreted in the context of the source of the information. Copyright © 2012 Osteoarthritis Research Society International. Published by Elsevier Ltd.

    The purpose of this study was to investigate the association between mode of delivery and the risk of celiac disease in two large population-based birth cohorts with different prevalence of diagnosed celiac disease. This is an observational register-based cohort study using two independent population cohorts. We used data from administrative registers and health administrative registers from Denmark and Norway and linked the data at the individual level. We included all children who were born in Denmark from January 1, 1995 to December 31, 2010 and all children who were born in Norway from January 1, 2004 to December 31, 2012. We included 1,051,028 children from Denmark. Cesarean sections were registered for 196,512 children (18.9%). Diagnosed celiac disease was registered for 1,395 children (0.13%). We included 537,457 children from Norway. Cesarean sections were registered for 90,128 children (16.8%). Diagnosed celiac disease was registered for 1,919 children (0.35%). We found no association between the mode of delivery and the risk of diagnosed celiac disease. The adjusted odds ratio for celiac disease for children delivered by any type of cesarean section compared to vaginal delivery was 1.11 (95% CI: 0.96-1.29) in the Danish cohort and 0.96 (95% CI: 0.84-1.09) in the Norwegian cohort. The adjusted odds ratio for celiac disease for children delivered by elective cesarean section compared to vaginal delivery was 1.20 (95% CI: 1.00-1.43) in the Danish cohort and 0.96 (95% CI: 0.79-1.17) in the Norwegian cohort. In this large registry-based study, mode of delivery was not associated with an increased risk of diagnosed celiac disease.

    Within Europe, the UK has one of the highest rates of self-harm, with a particularly high prevalence in children and young people (CYP). CYP who are admitted to paediatric hospital wards with self-harm are cared for by registered children's nurses who have been identified to lack specific training in caring for this patient group. This may impede the delivery of high quality care. Therefore, this study aims to co-produce, implement and evaluate an education programme for registered children's nurses to improve their knowledge, attitudes and confidence when caring for CYP admitted with self-harm. This mixed-methods evaluative study will involve a three-stage design. Stage 1: A priority-setting workshop will be conducted with 19 registered children's nurses. A Delphi technique will be used to establish consensus of information needs. Stage 2: An online educational intervention will be co-produced with 25 CYP and 19 registered children's nurses based on the priorities identified in Stage 1. Stage 3: The intervention will be implemented and evaluated with 250 registered children's nurses at a single hospital. Online Likert scale questionnaires will be administered at baseline and postintervention to assess levels of knowledge, attitudes and confidence in caring for CYP who self-harm. Descriptive and inferential statistics will be used to analyse the data. Statistical significance will be assessed at the 5% (two-sided) level. One-to-one qualitative interviews will also be undertaken with approximately 25 participants to explore any perceived impact on clinical practice. An interpretive descriptive approach will guide qualitative data collection and analysis. This study aims to develop, trial and evaluative a service-user, co-produced education programme for acute hospital registered children's nurses to improve the care of CYP admitted due to self-harm. The study has ethical approval from the National Health Services Research Ethics Committee and full governance clearance. Published by the BMJ Publishing Group Limited.

    The main topic treated in these graduate course notes is the classical theory of radiative transfer for explaining stellar spectra. It needs relatively much attention to be mastered. Radiative transfer in gaseous media that are neither optically thin nor fully opaque and scatter to boot is a key part of astrophysics but not a transparent subject. These course notes represent a middle road between Mihalas' "Stellar Atmospheres" (graduate level and up) and the books by Novotny and Boehm-Vitense (undergraduate level). They are at about the level of Gray's "The observation and analysis of stellar photospheres" but emphasize NLTE radiative transfer rather than observational techniques and data interpretation.

    The project KoRegIT (funded by TMF e.V.) aimed to develop a generic catalog of requirements for research networks like cohort studies and registers (KoReg). The catalog supports such kind of research networks to build up and to manage their organizational and IT infrastructure. To make transparent the complex relationships between requirements, which are described in use cases from a given text catalog. By analyzing and modeling the requirements a better understanding and optimizations of the catalog are intended. There are two subgoals: a) to investigate one cohort study and two registers and to model the current state of their IT infrastructure; b) to analyze the current state models and to find simplifications within the generic catalog. Processing the generic catalog was performed by means of text extraction, conceptualization and concept mapping. Then methods of enterprise architecture planning (EAP) are used to model the extracted information. To work on objective a) questionnaires are developed by utilizing the model. They are used for semi-structured interviews, whose results are evaluated via qualitative content analysis. Afterwards the current state was modeled. Objective b) was done by model analysis. A given generic text catalog of requirements was transferred into a model. As result of objective a) current state models of one existing cohort study and two registers are created and analyzed. An optimized model called KoReg-reference-model is the result of objective b). It is possible to use methods of EAP to model requirements. This enables a better overview of the partly connected requirements by means of visualization. The model based approach also enables the analysis and comparison of the empirical data from the current state models. Information managers could reduce the effort of planning the IT infrastructure utilizing the KoReg-reference-model. Modeling the current state and the generation of reports from the model, which could be used as requirements specification for bids, is supported, too.

    This study was designed to measure job satisfaction among registered clinical dentists so as to identify issues which may influence recruitment and retention of dentists in active clinical practice. A questionnaire measuring dimensions of job satisfaction was mailed to a stratified random sample of 80 private and 80 public sector dentists selected from the 1999 Victorian Dental Register. An adjusted response rate of 60 per cent was achieved (n = 87). Analyses showed significant differences (ANOVA; p < 0.05) in levels of satisfaction for various dimensions of job satisfaction by gender, age group and practice type. Differences in job satisfaction between male and female dentists related to the personal time dimension. Differences in satisfaction between dentists of different age groups were attributable to six dimensions: relationships with colleagues, relationships with patients, relationships with staff, personal time, community and administrative responsibilities. Differences between levels of satisfaction among private and public dentists related to the autonomy, relationships with patients, pay and resources dimensions. There are various dimensions of job satisfaction that may be pertinent to issues influencing recruitment and retention of dentists. Differences that exist between levels of job satisfaction among private and public sector dentists, between male and female dentists and dentists of different age groups need to be addressed in order to improve recruitment and retention rates of dentists in active clinical practice in different sectors of the dental care system.

    Recent studies have revealed key roles for granulocyte colony-stimulating factor (GCSF) in embryo implantation process and maintenance of pregnancy, and some studies showed promising results by using local intrauterine infusion of GCSF in patients undergoing in vitro fertilization (IVF). This multicenter, randomized, controlled trial included 112 infertile women with repeated IVF failure to evaluate the efficacy of systemic single-dose subcutaneous GCSF administration on IVF success in these women. In this study, the Long Protocol of ovarian stimulation was used for all participants. Sealed, numbered envelopes assigned 56 patients to receive subcutaneous 300 µg GCSF before implantation and 56 in the control group. The implantation (number of gestational sacs on the total number of transferred embryos), chemical pregnancy (positive serum β-HCG), and clinical pregnancy (gestational sac and fetal heart) rates were compared between the two groups. This trial is registered at www.irct.ir (IRCT201503119568N11). The successful implantation (18% vs 7.2%, P=0.007), chemical pregnancy (44.6% vs 19.6%, P=0.005), and clinical pregnancy (37.5% vs 14.3%, P=0.005) rates were significantly higher in the intervention group than in the control group. After adjustment for participants' age, endometrial thickness, good-quality oocyte counts, number of transferred embryos, and anti-Mullerian hormone levels, GCSF treatment remained significantly associated with successful implantation (OR=2.63, 95% CI=1.09-6.96), having chemical pregnancy (OR= 2.74, 95% CI=1.11-7.38) and clinical pregnancy (OR=2.94, 95% CI=1.23-8.33). In conclusion, administration of single-dose systemic subcutaneous GCSF before implantation significantly increases the IVF success, implantation, and pregnancy rates in infertile women with repeated IVF failure. © 2016 Society for Reproduction and Fertility.

    Laparoscopic surgery is a minimally invasive surgical approach, in which abdominal surgical procedures are performed through trocars via small incisions. Patients benefit by reduced postoperative pain, shortened hospital stays, improved cosmetic results, and faster recovery times. Optimal port placement can improve surgeon dexterity and avoid the need to move the trocars, which would cause unnecessary trauma to the patient. We are building an intuitive open source visualization system to help surgeons identify ports. Our methodology is based on an intuitive port placement visualization module and atlas-based registration algorithm to transfer port locations to individual patients. The methodology follows three steps:1) Use a port placement visualization module to manually place ports in an abdominal organ atlas. This step generates port-augmented abdominal atlas. This is done only once for a given patient population. 2) Register the atlas data with the patient CT data, to transfer the prescribed ports to the individual patient 3) Review and adjust the transferred port locations using the port placement visualization module. Tool maneuverability and target reachability can be tested using the visualization system. Our methodology would decrease the amount of physician input necessary to optimize port placement for each patient case. In a follow up work, we plan to use the transferred ports as starting point for further optimization of the port locations by formulating a cost function that will take into account factors such as tool dexterity and likelihood of collision between instruments.

  7. Hybrid male sterility between Drosophila willistoni species is caused by male failure to transfer sperm during copulation.

    PubMed

    Civetta, Alberto; Gaudreau, Chelsea

    2015-05-01

    The biological concept of species stresses the importance of understanding what mechanisms maintain species reproductively isolated from each other. Often such mechanisms are divided into premating and postmating, with the latest being the result of either prezygotic or postzygotic isolation barriers. Drosophila willistoni quechua and Drosophila willistoni willistoni are two subspecies that experience reproductive isolation. When a D. w. quechua female is crossed with a D. w. willistoni male, the hybrid males (F1QW) are unable to father progeny; however, the reciprocal cross produces fertile hybrids. Thus, the mechanism of isolation is unidirectional hybrid male sterility. However, the sterile F1QW males contain large amounts of motile sperm. Here we explore whether pre-copulatory or post-copulatory pre-zygotic mechanisms serve as major deterrents in the ability of F1QW males to father progeny. Comparisons of parental and hybrid males copulation durations showed no significant reduction in copulation duration of F1QW males. Interrupted copulations of the parental species confirmed that sperm transfer occurs before the minimum copulation duration registered for F1QW males. However, we found that when females mate with F1QW males, sperm is not present inside the female storage organs and that the lack of sperm in storage is due to failure to transfer sperm rather than spillage or active sperm dumping by females. Sterility of F1QW hybrid males is primarily driven by their inability to transfer sperm during copulation.

    The role of level 3 trauma centres (TC) in inclusive trauma systems has not been well defined. The absence of nationally recognised inter-facility transfer criteria for inclusive systems has often left individual level 3 TCs to decide upon their own what their spectrum of care is and particularly which severely injured patients to admit for definitive care. Retrospective cohort study in which the principal objective was to compare the characteristics and outcomes of severely injured (injury severity score>15) adult patients (≥18 years) who received definitive care at level 3 centres with severely injured adult patients who were transferred to level 1-2 TCs during the same time period. Data were derived from the National Trauma Data Bank (2010-2011). First, we utilised hierarchical logistic regression models to evaluate the risk-adjusted mortality of patients admitted at level 3 TCs compared to those who were transferred to level 1-2 TCs. Subgroup analysis was carried out for patients with isolated traumatic brain injury (iTBI). Finally, we explored the extent of variation in risk-adjusted mortality across level 3 TCs. We identified 6433 severely injured patients who received definitive care across 150 level 3 TCs and 41,165 severely injured patients transferred to level 1-2 centres. Patients who received definitive care at level 3 TCs had a lower comorbidity burden and different injury profiles compared to those transferred to level 1-2 centres. There was no difference in crude mortality (10% vs. 11%, standardised difference 0.04); however, after risk-adjustment, the odds of death for patients who received definitive care at level 3 TCs were 1.24-fold higher (95%CI 1.08-1.43) when compared to those transferred to level 1-2 centres. A trend towards a higher likelihood of death at level 3 centres was observed when analysis was limited to patients with iTBI. Risk-adjusted mortality across level 3 TCs was with few exceptions, homogeneous (<10% of level 3 TCs were outliers with higher/lower mortality). Level 3 trauma centres are providing definitive care for a subset of severely injured patients. Our findings suggest that the outcomes of severely injured patients admitted at level 3 centres might be worse compared to those transferred to level 1-2 centres; a finding independent of performance outliers. Further work is required to elucidate the determinants of admission after severe injury at level 3 trauma centres. Copyright © 2015 Elsevier Ltd. All rights reserved.

  13. A genealogical survey of Australian registered dog breeds.

    2011-08-01

    Breeding practices were analysed for 32 registered dog breeds representing very small registries (120 Central Asian shepherd dogs) through to very large registries (252,521 German shepherd dogs) in Australia. The vast majority (91%) of registered kennels in Australia that were sampled did not regularly employ either close breeding or popular sire usage in their kennels and the weighted mean inbreeding coefficient of Australian pedigree dogs was <5%. Australian breed mean inbreeding coefficients ranged from 0% (Central Asian shepherd dog) to 10.1% (Bichon Frise). Breed effective population sizes ranged from 26 (Ibizan hound) to 1090 (Golden retriever), comparable with other species of domesticated animals. The relatively low levels of inbreeding suggest that pedigree dog disorders are unlikely to arise frequently from the use of popular sires or close breeding in Australian registered dog breeds. It is possible that deleterious allele fixation might be driven by founder effects, genetic drift or adverse selection practices, which were not assessed in this analysis. European popular sire definitions should be revisited for rare breeds. Copyright © 2011. Published by Elsevier Ltd.

  14. Optimal thrust level for orbit insertion

    2017-07-01

    The minimum-fuel orbital transfer is analyzed in the case of a launcher upper stage using a constantly thrusting engine. The thrust level is assumed to be constant and its value is optimized together with the thrust direction. A closed-loop solution for the thrust direction is derived from the extremal analysis for a planar orbital transfer. The optimal control problem reduces to two unknowns, namely the thrust level and the final time. Guessing and propagating the costates is no longer necessary and the optimal trajectory is easily found from a rough initialization. On the other hand the initial costates are assessed analytically from the initial conditions and they can be used as initial guess for transfers at different thrust levels. The method is exemplified on a launcher upper stage targeting a geostationary transfer orbit.

  15. Hair and fiber transfer in an abduction case--evidence from different levels of trace evidence transfer.

    1996-07-01

    Levels of trace evidence transfer were examined in a casework context. A girl was allegedly abducted in a car and rape attempted by the accused, who denied any contact with the victim. Clothing worn by the victim and the accused, and the covers from the front seats of the car, were analyzed for trace evidence. Three types of corresponding fibers and four possible pathways of transfer were identified. Synthetic fibers similar to those composing the car seat covers were located on the victim's clothing, consistent with direct transfer. Secondary transfer was indicated by dyed brown human head-type hairs (possibly originating from the accused's wife) located on the seat covers and on the victim's clothing. Secondary and possibly tertiary transfer was indicated by pink synthetic material and associated fibers (possibly originating from the victim's mother) located on the victim's clothing, a car seat cover and the accused's clothing. Light microscopy, comparison microscopy, and cross-sectioning techniques were used. The multiple fiber matches and the differing pathways and levels of transfer increased the strength of the association between the accused and the victim. After the fiber evidence was led at the trial, the accused pleaded guilty, thereby affirming the value of secondary transfer evidence.

    With the increased interest in internationalization, many western universities have been working to attract students from China and other Asian countries. Texas A&M University has had a collaborative Ph.D. program with Ocean University, Qingdao, China since 2008. Chinese students spend their first one or two years in Qingdao, then transfer to TAMU to complete their coursework and carry out research. The program has so far produced 6 PhDs and one MS degree, and another 14 students are registered through the program. We anticipate sending U.S. students to China on a reciprocal basis, although the lack of Chinese-speaking U.S. students is an issue. Additionally, the Memorandum of Understanding has led to joint research projects between the two universities, with publications in top journals. Novel aspects of the program include joint funding by the U.S. and China, co-chairing graduate committees by both university faculties, interviewing students in Qingdao before they are accepted by TAMU, and initial studies in one country and then transfer to the other. Such programs require 'heroes' on each side to set up and continue the program who trust each other, as well as support from the upper administration. Even with such support, outside influences and different cultures can affect the effectiveness of the program.

    To examine the regular and overtime working hours of Registered Nurses in acute care and their associated costs by employment status (full time, part time, casual) and department over a 4-year period. Data were extracted for 2005-2008 from one health region's payroll database for Registered Nurses in acute care in British Columbia, Canada. Regular and overtime hours by employment status and department were plotted over time and tested using simple linear regression. Regular and overtime wage costs were calculated at the individual level using the employee's wage rate and stratified by year, gender, age, employment status and department. Full time Registered Nurses are working an increasing amount of overtime hours each year. Full time nurses in Emergency, Intensive Care and General Medical departments are working the highest proportion of overtime hours per total hours and consequently, contributing the highest proportion of overtime costs. Efforts to lighten the burden of overtime should be focused at the department level. Creating more full time positions out of overtime hours may be one solution to alleviate this burden of overtime and to assuage the nursing shortage in Canada.

    2009-08-01

    Burnout is considered a major negative outcome of work related distress in social and health care services, especially in nursing. In the present study 179 student nurses in their third year of training and 47 registered nurses, all working in the Austrian province of Salzburg, were examined with the Maslach Burnout Inventory and the Satisfaction With Life Scale. Compared on a regional and national level, burnout scores of student nurses were equal to those of registered nurses and workers in social and nursing professions. The specific stressors of education and training lead to strain comparable to years of professional experience and exposure to stressors. The relatively high level of satisfaction with life in student nurses may be due to specific resources and ways of compensation, that require further examination. Differences between urban and rural districts (with lower burnout scores and higher satisfaction with life sores in rural districts) were strong in student nurses. Compared with international nurse and health care samples, burnout is relatively low in the examined groups. Registered nurses and student nurses in rural districts show the lowest scores of all in emotional exhaustion and depersonalization, respectively.

    Studies of trophic-level material and energy transfers are central to ecology. The use of isotopic tracers has now made it possible to measure trophic transfer efficiencies of important nutrients and to better understand how these materials move through food webs. We analyzed data from thirteen 15N-ammonium tracer addition experiments to quantify N transfer from basal resources to animals in headwater streams with varying physical, chemical, and biological features. N transfer efficiencies from primary uptake compartments (PUCs; heterotrophic microorganisms and primary producers) to primary consumers was lower (mean: 11.5%, range: <1%-43%) than N transfer efficiencies from primary consumers to predators (mean:more » 80%, range: 5%- >100%). Total N transferred (as a rate) was greater in streams with open compared to closed canopies and overall N transfer efficiency generally followed a similar pattern, although was not statistically significant. We used principal component analysis to condense a suite of site characteristics into two environmental components. Total N uptake rates among trophic levels were best predicted by the component that was correlated with latitude, DIN:SRP, GPP:ER, and % canopy cover. N transfer efficiency did not respond consistently to environmental variables. Here, our results suggest that canopy cover influences N movement through stream food webs because light availability and primary production facilitate N transfer to higher trophic levels.« less

    An event-driven X-ray CCD imager device uses a floating-gate amplifier or other non-destructive readout device to non-destructively sense a charge level in a charge packet associated with a pixel. The output of the floating-gate amplifier is used to identify each pixel that has a charge level above a predetermined threshold. If the charge level is above a predetermined threshold the charge in the triggering charge packet and in the charge packets from neighboring pixels need to be measured accurately. A charge delay register is included in the event-driven X-ray CCD imager device to enable recovery of the charge packets from neighboring pixels for accurate measurement. When a charge packet reaches the end of the charge delay register, control logic either dumps the charge packet, or steers the charge packet to a charge FIFO to preserve it if the charge packet is determined to be a packet that needs accurate measurement. A floating-diffusion amplifier or other low-noise output stage device, which converts charge level to a voltage level with high precision, provides final measurement of the charge packets. The voltage level is eventually digitized by a high linearity ADC.

    We studied the electron transfer at the interface of organic-inorganic hybrids consisting of indoline derivatives (D149 and D131) on ZnO substrates using a new optical method. We revealed the electron transfer times from the excited dye, e.g. the excitons formed in the dye aggregates to the ZnO substrate by analyzing the photoluminescence transients of the excitons after femtosecond excitation and applying kinetic model calculations. We reveal the changes of the electron transfer times by applying electrical bias. Pushing the Fermi energy of the ZnO substrate towards the excited dye level the transfer time gets longer and eventually the electron transfer is suppressed. The level alignment between the excited dye state and the ZnO Fermi-level is estimated. The excited state of D131 is about 100 meV higher than the respective state of D149 compared to the ZnO conduction band. This leads to shorter electron transfer times and eventually to higher quantum efficiencies of the solar cells.

    2012-01-01

    We evaluated serum level of S100B in 11 patients with subcortical vascular dementia (SVD) and 19 patients with subcortical vascular mild cognitive impairment (SVMCI). Comparable groups were age-matched (79.18 +/- 7.76 in SVD group, 77.84 +/- 3.83 in SVMCI; P = 0.53). 22 patients were assessed after 1 month therapy. It was shown that the serum S100B level significantly increased--(0.065 +/- 0.020) micro/l (P = 0.0005) in SVD patients comparing to SVMCI ones - (0.043 +/- 0.010) microg/l. S100B level was significantly correlated with the clinical parameters: MMSE performance (r(s) = -0.61), CDR (r(s) = 0.58), attention task (r(s) = -0.46), pseudobulbar syndrome severity (r(s) = 0.37) and walking alteration (r(s)= 0.37). In patients with reduction of S100B level due to therapy (positive dynamics, n = 12) we registered significant improvement of some clinical parameters: MMSE, attention level, walking. In patients with increasing of S100B level (negative dynamics, n = 10) we didn't registered improvement of any clinical parameters. We made the conclusion that the serum level of S100B could be used as marker of progression SVMCI into SVD and therapy effectiveness.

  6. Unstable Memories Create a High-Level Representation that Enables Learning Transfer.

    PubMed

    2016-01-11

    A memory is unstable, making it susceptible to interference and disruption, after its acquisition [1-4]. The function or possible benefit of a memory being unstable at its acquisition is not well understood. Potentially, instability may be critical for the communication between recently acquired memories, which would allow learning in one task to be transferred to the other subsequent task [1, 5]. Learning may be transferred between any memories that are unstable, even between different types of memory. Here, we test the link between a memory being unstable and the transfer of learning to a different type of memory task. We measured how learning in one task transferred to and thus improved learning in a subsequent task. There was transfer from a motor skill to a word list task and, vice versa, from a word list to a motor skill task. What was transferred was a high-level relationship between elements, rather than knowledge of the individual elements themselves. Memory instability was correlated with subsequent transfer, suggesting that transfer was related to the instability of the memory. Using different methods, we stabilized the initial memory, preventing it from being susceptible to interference, and found that these methods consistently prevented transfer to the subsequent memory task. This suggests that the transfer of learning across diverse tasks is due to a high-level representation that can only be formed when a memory is unstable. Our work has identified an important function of memory instability. Copyright © 2016 Elsevier Ltd. All rights reserved.

To examine the effects of a one hour, educational intervention on Emergency Medicine (EM) residents' and Critical Care (CC) fellows' knowledge regarding the medical and legal aspects of interfacility patient transfers. Prior to the intervention, physician knowledge regarding 12 key concepts in patient transfer was assessed using a pre-test instrument. A one hour, interactive, educational session followed immediately thereafter. Following the intervention, a post-intervention test was given between two and four weeks after delivery. Participants were also asked to describe any prior transportation-medicine-related education, their opinions as they relate to the relevance of the topic, and their comfort levels with patient transfers before and after the intervention. Only a minority of participants had received any formal training in patient transfers prior to the intervention, despite dealing with patient transfers on a frequent, often daily, basis. Both groups improved in several categories on the post-intervention test. They reported improved comfort levels with the medicolegal aspects of interfacility patient transfers after the intervention and felt well-prepared to manage transfers in their daily practice. A one hour, educational intervention objectively increased EM and CC physician trainees' understanding of some of the medicolegal aspects of interfacility patient transfers. The study demonstrated a lack of previous training on this important topic and improved levels of comfort with transfers after study participation.

    The aim of the present study was to assess how socio-economic background influences perception of an adverse postoperative event after hernia surgery, and to see if this affects the pattern of seeking healthcare advice during the early postoperative period. All patients aged 15 years or older with a primary unilateral inguinal or femoral hernia repair recorded in the Swedish Hernia Register (SHR) between November 1 and December 31, 2002 were sent a questionnaire inquiring about adverse events. Data on civil status, income, level of education and ethnic background were obtained from Statistics Sweden. Of the 1643 patients contacted, 1440 (87.6%) responded: 1333 (92.6%) were men and 107 (7.4%) women, mean age was 59 years. There were 203 (12.4%) non-responders. Adverse events were reported in the questionnaire by 390 (27.1%) patients. Patients born in Sweden and patients with high income levels reported a significantly higher incidence of perceived adverse events (p < 0.05). Patients born in Sweden and females reported more events requiring healthcare contact. There was no association between registered and self-reported outcome and civil status or level of education. We detected inequalities related to income level, gender and ethnic background. Even if healthcare utilization is influenced by socio-economic background, careful information of what may be expected in the postoperative period and how adverse events should be managed could lead to reduced disparity and improved quality of care in the community at large.

    We calculate vibrational levels and wave functions for HO2 using the recently reported ab initio potential energy surface of Walch and Duchovic. There is intramolecular hydrogen atom transfer when the hydrogen atom tunnels through a T-shaped saddle point separating two equivalent equilibrium geometries, and correspondingly, the energy levels are split. We focus on vibrational levels and wave functions with significant splitting. The first three vibrational levels with splitting greater than 2/cm are (15 0), (0 7 1) and (0 8 0) where V(sub 2) is the O-O-H bend quantum number. We discuss the dynamics of hydrogen atom transfer; in particular, the O-O distances at which hydrogen atom transfer is most probable for these vibrational levels. The material of the proposed presentation was reviewed and the technical content will not reveal any information not already in the public domain and will not give any foreign industry or government a competitive advantage.

    Cash transfers and vouchers are forms of 'demand-side financing' that have been widely used to promote maternal and newborn health in low- and middle-income countries during the last 15 years. This systematic review consolidates evidence from seven published systematic reviews on the effects of different types of cash transfers and vouchers on the use and quality of maternity care services, and updates the systematic searches to June 2015 using the Joanna Briggs Institute approach for systematic reviewing. The review protocol for this update was registered with PROSPERO (CRD42015020637). Data from 51 studies (15 more than previous reviews) and 22 cash transfer and voucher programmes suggest that approaches tied to service use (either via payment conditionalities or vouchers for selected services) can increase use of antenatal care, use of a skilled attendant at birth and in the case of vouchers, postnatal care too. The strongest evidence of positive effect was for conditional cash transfers and uptake of antenatal care, and for vouchers for maternity care services and birth with a skilled birth attendant. However, effects appear to be shaped by a complex set of social and healthcare system barriers and facilitators. Studies have typically focused on an initial programme period, usually two or three years after initiation, and many lack a counterfactual comparison with supply-side investment. There are few studies to indicate that programmes have led to improvements in quality of maternity care or maternal and newborn health outcomes. Future research should use multiple intervention arms to compare cost-effectiveness with similar investment in public services, and should look beyond short- to medium-term service utilisation by examining programme costs, longer-term effects on service utilisation and health outcomes, and the equity of those effects.

  11. Transfer of learning in choice reactions: The roles of stimulus type, response mode, and set-level compatibility.

    The Simon effect refers to the advantage of responding to spatially compatible stimuli. This effect can be eliminated or even reversed to favor spatially incompatible stimuli after participants practice a choice-reaction task with spatially incompatible mappings (e.g., pressing left and right keys to stimuli on the right and left, respectively). This transfer of incompatible spatial associations has been observed under conditions in which responses were made manually (e.g., keypresses, moving a joystick). The present study used vocal responses to reveal the primary determinants of the transfer effect, dissociating the influences of stimulus type, response mode, and their interaction (set-level compatibility). The results suggest that contextual match between the practice and transfer tasks with respect to stimulus type and response mode determined transfer of incompatible associations to the Simon task, and stimulus type determined the efficiency of acquiring new associations. However, there was little evidence that set-level compatibility plays any major role in either acquisition or transfer of spatial associations.

    Nursing turnover is a major issue for health care managers, notably during the global nursing workforce shortage. Despite the often hierarchical structure of the data used in nursing studies, few studies have investigated the impact of the work environment on intention to leave using multilevel techniques. Also, differences between intentions to leave the current workplace or to leave the profession entirely have rarely been studied. The aim of the current study was to investigate how aspects of the nurse practice environment and satisfaction with work schedule flexibility measured at different organisational levels influenced the intention to leave the profession or the workplace due to dissatisfaction. Multilevel models were fitted using survey data from the RN4CAST project, which has a multi-country, multilevel, cross-sectional design. The data analysed here are based on a sample of 23,076 registered nurses from 2020 units in 384 hospitals in 10 European countries (overall response rate: 59.4%). Four levels were available for analyses: country, hospital, unit, and individual registered nurse. Practice environment and satisfaction with schedule flexibility were aggregated and studied at the unit level. Gender, experience as registered nurse, full vs. part-time work, as well as individual deviance from unit mean in practice environment and satisfaction with work schedule flexibility, were included at the individual level. Both intention to leave the profession and the hospital due to dissatisfaction were studied. Regarding intention to leave current workplace, there is variability at both country (6.9%) and unit (6.9%) level. However, for intention to leave the profession we found less variability at the country (4.6%) and unit level (3.9%). Intention to leave the workplace was strongly related to unit level variables. Additionally, individual characteristics and deviance from unit mean regarding practice environment and satisfaction with schedule flexibility were related to both outcomes. Major limitations of the study are its cross-sectional design and the fact that only turnover intention due to dissatisfaction was studied. We conclude that measures aiming to improve the practice environment and schedule flexibility would be a promising approach towards increased retention of registered nurses in both their current workplaces and the nursing profession as a whole and thus a way to counteract the nursing shortage across European countries.

  13. Transfer reservoir as a new solution for transfer of stormwater to water receivers

    2017-11-01

    With frequent heavy rainfalls in summer in Poland and fast-melting snow in spring leading to flooding of sewage systems (due to excessive filling levels in water receivers or difficulties with temporary retention of the excess stormwater), a variety of systems are being developed to facilitate transfer of the stormwater to water receivers. Outflow of the excess stormwater is usually ensured by the use of gravitational outflow collectors that connect stormwater drains with waterways. The transfer occurs during intensive precipitation, when the excess wastewater overflows through stormwater drains and is transferred directly to water receivers in order to relieve wastewater treatment plants or to minimize diameters of sewers. These systems are useful wherever the filling levels in waterways are not very high or the sewerage system is located relatively high with respect to the water receiver i.e. outflow collector is located on a steep slope. In such cases, the stormwater that flows through a waterway cannot be returned to the outflow collector. If the gravitational flow is impossible e.g. due to the excessive filling level of water receiver, stormwater can be transferred by means of a variety of modern solutions, such as retention and transfer reservoirs. These reservoirs are supposed to ensure partial retention of the excess stormwater and transfer of this water to water receivers, either gravitationally or forced mechanically, depending on the filling level in the waterway. Furthermore, these reservoirs prevent wastewater from being returned to the system during suddenly rising levels. One of the solutions is offered by the reservoir presented in this paper. The transfer reservoir for the stormwater presented in this paper might be successfully used in modernization of current sewage systems, ensuring the reliability of operation and a more effective wastewater transfer than the systems used to date. All the reservoirs of this type are characterized by similar design and function and guarantee that the wastewater might be transferred regardless of the conditions in the water receiver. An essential feature of these reservoirs is the use of the effective method to control suction and pumping units.

    In minimally invasive image-guided surgical interventions, different imaging modalities, such as magnetic resonance imaging (MRI), computed tomography (CT), and real-time three-dimensional (3D) ultrasound (US), can provide complementary, multi-spectral image information. Multimodality dynamic image registration is a well-established approach that permits real-time diagnostic information to be enhanced by placing lower-quality real-time images within a high quality anatomical context. For the guidance of cardiac procedures, it would be valuable to register dynamic MRI or CT with intraoperative US. However, in practice, either the high computational cost prohibits such real-time visualization of volumetric multimodal images in a real-world medical environment, or else the resulting image quality is not satisfactory for accurate guidance during the intervention. Modern graphics processing units (GPUs) provide the programmability, parallelism and increased computational precision to begin to address this problem. In this work, we first outline our research on dynamic 3D cardiac MR and US image acquisition, real-time dual-modality registration and US tracking. Then we describe image processing and optimization techniques for 4D (3D + time) cardiac image real-time rendering. We also present our multimodality 4D medical image visualization engine, which directly runs on a GPU in real-time by exploiting the advantages of the graphics hardware. In addition, techniques such as multiple transfer functions for different imaging modalities, dynamic texture binding, advanced texture sampling and multimodality image compositing are employed to facilitate the real-time display and manipulation of the registered dual-modality dynamic 3D MR and US cardiac datasets.

    Objectives Uptake of healthcare among migrants is a complex and controversial topic; there are multiple recognised barriers to accessing primary care. Delays in presentation to healthcare services may result in a greater burden on costly emergency care, as well as increased public health risks. This study aimed to explore some of the factors influencing registration of new entrants with general practitioners (GPs). Design Retrospective cohort study. Setting Port health screening at Heathrow and Gatwick airports, primary care. Participants 252 559 new entrants to the UK, whose entry was documented by the port health tuberculosis screening processes at Heathrow and Gatwick. 191 had insufficient information for record linkage. Primary outcome measure Registration with a GP practice within the UK, as measured through record linkage with the Personal Demographics Service (PDS) database. Results Only 32.5% of 252 368 individuals were linked to the PDS, suggesting low levels of registration in the study population. Women were more likely to register than men, with a RR ratio of 1.44 (95% CI 1.41 to 1.46). Compared with those from Europe, individuals of nationalities from the Americas (0.43 (0.39 to 0.47)) and Africa (0.74 (0.69 to 0.79)) were less likely to register. Similarly, students (0.83 (0.81 to 0.85)), long-stay visitors (0.82 (0.77 to 0.87)) and asylum seekers (0.46 (0.42 to 0.51)) were less likely to register with a GP than other migrant groups. Conclusions Levels of registration with GPs within this selected group of new entrants, as measured through record linkage, are low. Migrant groups with the lowest proportion registered are likely to be those with the highest health needs. The UK would benefit from a targeted approach to identify the migrants least likely to register for healthcare and to promote access among both users and service providers. PMID:22869094

    The aim of this study was to investigate the attitudes of general practitioners (GPs) to the development of a national diabetes register as a way of improving the quality of care. Qualitative study using semistructured interviews. General practice, Ireland. Purposive sample of 29 GPs and two practice nurses. Participants' practices varied by (a) location (rural/urban), (b) size (single-handed/group practice) and (c) extent of computerisation. The semistructured topic guide focused on experiences of change in the health system at a local and national level and attitudes towards the development of a national diabetes register. Analysis was conducted using the Framework approach. Participants were sceptical about the development of a national diabetes register. The main advantage was 'knowing the numbers' for epidemiological and policy purposes. However, participants questioned the benefits for their practice and patients. There were concerns that it would drain resources from other priorities and distract from patient management. These attitudes were strongly influenced by previous experience of change in the health system. Participants felt that remuneration would be necessary to ensure full engagement, reflecting wider frustrations with payment structures for general practice. There was a sense of wariness towards health service administration which was not specific to diabetes care but which coloured some participants' attitudes towards a national register. In contrast, participants referred to positive experiences of change at a local level, facilitated by a 'practice ethos' and professional leadership. This study highlights the growing sense of scepticism and inertia towards change within the health system. This inertia stems from previous experience and the competing demands of maintaining versus improving care in a system with dwindling resources. Published by the BMJ Publishing Group Limited.

    Background Rates of prostate specific antigen (PSA) test ordering vary among GPs. Aim To examine whether GPs’ risk attitude, level of empathy, and burnout status are associated with PSA testing. Design and setting Register and questionnaire study including 129 solo GPs (active in the Central Denmark Region) and 76 672 of their adult male patients with no history of or current prostate cancer diagnosis. Method PSA tests from 2012 were retrieved from a register and classified as incident (that is, the first PSA test within 24 months), repeated normal, or repeated raised tests. This was merged with information on GPs’ risk attitudes, empathy, and burnout status from a 2012 survey. Results Patients registered with a GP with a high score on anxiety caused by uncertainty (odds ratio [OR] 1.03, 95% confidence interval [CI] = 1.00 to 1.06, P = 0.025) or concern about bad outcomes (OR 1.04; 95% CI = 1.00 to 1.08, P = 0.034) were more likely to have an incident PSA test, whereas those registered with a GP with increased tolerance for ambiguity were less likely (OR 0.98, 95% CI = 0.96 to 1.00, P = 0.025). Patients registered with a GP reporting high tolerance for ambiguity (OR 0.96, 95% CI = 0.94 to 0.99, P = 0.009) or high propensity to risk-taking (OR 0.97, 95% CI = 0.93 to 1.00, P = 0.047) were less likely to have a repeated normal PSA test. Conclusion Various aspects of GPs’ risk-taking attitudes were associated with patients’ probability of having an incident and a repeated normal PSA test. The probability of having a repeated raised PSA test was not influenced by any of the psychological factors. Burnout and empathy were not associated with PSA testing. PMID:26541183

    Left-behind children (LBC) are recognised as a new social group in China. LBC are young children who are abandoned in rural villages whilst their parents travel to distant urban centres for employment (a new generation of migrant workers). Following the rapid growth in the number of migrant workers, the LBC population is also rapidly increasing. These children are usually left to be raised by elderly grandparents, a single parent, or sometimes distant relatives or neighbours who have limited resources, tend to have a poor education and sometimes are in frail health. Over 40 % of the 61 million LBC in China who are under 5 years old are undernourished, which affects their long-term health and abilities. An intervention that combines a conditional cash transfer (CCT) with nutrition education offers a potential solution. A cluster randomised controlled trial design will be used to allocate 40 villages to the intervention arm (20 villages) or control arm (20 villages). The caregivers and all of the 3-5-year-old LBC will be the target population. Caregivers in the intervention arm will receive a cash allowance conditional on attending nutrition education sessions, ensuring that the LBC will use basic public health services over a 12-month period. At the baseline, midterm (month 6) and end (month 12) of the intervention period, evaluations will be conducted in all 40 villages. Multilevel generalised linear models will be used to analyse the impact of the intervention on nutrition status and other outcomes, adjusting for baseline levels using an analysis of covariance approach. The cost of the intervention will also be estimated. If found to be cost-effective, the findings will inform the development of a sustainable model to improve nutrition status among LBC in rural areas of China.

    Turbulence was generated by using screens, and the turbulence percentage was measured by a hot-wire anemometer both in the boundary layer and the free stream. The local heat-transfer coefficient was measured at 12 locations along the plate for the cases of various turbulence levels. The transition Reynolds number from laminar to turbulent flow decreases as the main-stream turbulence level increases. In the range of laminar heat transfer the effect of turbulence in the main flow was not great, but in the range of turbulent heat transfer the heat-transfer coefficient increases according to the increase of turbulence.
