Attitudes About the Use of Newborn Dried Blood Spots for Research: A Survey of Underrepresented Parents

Objective To identify the relative importance of factors that impact parents’ attitudes toward use of their child’s dried newborn blood spots for research purposes. Methods Respondents were parents aged 18 and older with at least one child aged 17 or younger born in Indiana visiting an urban pediatrics clinic. They were asked to rate the acceptability of hypothetical scenarios involving the research use of blood spots. Three pieces of information varied between the scenarios: 1) who would be conducting the research; 2) whether the child’s identity would be linked to the spots; and 3) whether and how often the parents’ consent would be sought before the research began. Results A total of 506 predominantly black and low-income parents completed the survey. The conjoint analysis model showed good fit (Pearson’s R = 0.998, P < .001). The rank order of factors affecting parents’ attitudes was: 1) consent (importance score = 64.9), 2) whether the child’s identity was linked to the spot (importance score = 19.4), and 3) affiliation of the researcher using the spots (importance score = 14.6). Respondents preferred being asked for their consent each time their children’s spots would be used. They preferred that the children’s identity not be linked to the spots and that the research be conducted by university researchers, though these issues had less impact on attitudes than consent. Conclusions Parents strongly prefer that consent be sought for each use of their children’s blood spots. These findings have implications for future research and policy-making decisions

A Needs Assessment to Build International Research Ethics Capacity at Moi University

International Research Ethics Partnership. This online version is the post-print version (final, peer-reviewed and accepted for publication version) of the published article. For the published version, refer to the article citation within the item record.International collaborators in biomedical sciences face ethical challenges in the design,review, and conduct of research. Challenges include differences in research ethics capacity, cultural differences in interpretation and application of ethical principles, and cooperation between ethics review boards at collaborating institutions. Indiana University School of Medicine (Indianapolis, USA) and Moi University Faculty of Health Sciences (Eldoret, Kenya)developed a Memorandum of Understanding (MOU) to establish greater cooperation between their ethics review boards, followed by a joint needs assessment to assess barriers to implementing the MOU. Focus groups and interviews at each institution revealed that while each side verbalized understanding and respect for the other's culture, there were misunderstandings deeply rooted in each culture that could potentially derail the collaboration. Although the participants at each university agreed on the major principles and issues in research ethics and on the importance attributed to them, a more in-depth evaluation of the responses revealed important differences. Methods to address these misunderstandings are outlined in the recommended Best Practices.Fogarty International Center at the NIH, Indiana University Division of General Internal Medicine and Geriatrics, Indiana University School of Medicine, Indiana University International Development Fund, Indiana Genomics Initiative, Lilly Endowment, Inc

Bulk high-Tc superconductors with drilled holes: how to arrange the holes to maximize the trapped magnetic flux ?

Drilling holes in a bulk high-Tc superconductor enhances the oxygen annealing and the heat exchange with the cooling liquid. However, drilling holes also reduces the amount of magnetic flux that can be trapped in the sample. In this paper, we use the Bean model to study the magnetization and the current line distribution in drilled samples, as a function of the hole positions. A single hole perturbs the critical current flow over an extended region that is bounded by a discontinuity line, where the direction of the current density changes abruptly. We demonstrate that the trapped magnetic flux is maximized if the center of each hole is positioned on one of the discontinuity lines produced by the neighbouring holes. For a cylindrical sample, we construct a polar triangular hole pattern that exploits this principle; in such a lattice, the trapped field is ~20% higher than in a squared lattice, for which the holes do not lie on discontinuity lines. This result indicates that one can simultaneously enhance the oxygen annealing, the heat transfer, and maximize the trapped field

Patient Preferences in Controlling Access to Their Electronic Health Records: a Prospective Cohort Study in Primary Care

Introduction: Previous studies have measured individuals’ willingness to share personal information stored in electronic health records (EHRs) with health care providers, but none has measured preferences among patients when they are allowed to determine the parameters of provider access. Methods: Patients were given the ability to control access by doctors, nurses, and other staff in a primary care clinic to personal information stored in an EHR. Patients could restrict access to all personal data or to specific types of sensitive information, and could restrict access for a specific time period. Patients also completed a survey regarding their understanding of and opinions regarding the process. Results: Of 139 eligible patients who were approached, 105 (75.5 %) were enrolled, and preferences were collected from all 105 (100 %). Sixty patients (57 %) did not restrict access for any providers. Of the 45 patients (43 %) who chose to limit the access of at least one provider, 36 restricted access only to all personal information in the EHR, while nine restricted access of some providers to a subset of the their personal information. Thirty-four (32.3 %) patients blocked access to all personal information by all doctors, nurses, and/or other staff, 26 (24.8 %) blocked access by all doctors and/or nurses, and five (4.8 %) denied access to all doctors, nurses, and staff. Conclusions: A significant minority of patients chose to restrict access by their primary care providers to personal information contained in an EHR, and few chose to restrict access to specific types of information. More research is needed to identify patient goals and understanding of the implications when facing decisions of this sort, and to identify the impact of patient education regarding information contained in EHRs and their use in the clinical care settin

Apatites in Gale Crater

ChemCam is an active remote sensing instrument suite that has operated successfully on MSL since landing Aug. 6th, 2012. It uses laser pulses to remove dust and to analyze rocks up to 7 m away. Laser-induced breakdown spectroscopy (LIBS) obtains emission spectra of materials ablated from the samples in electronically excited states. The intensities of the emission lines scale with the abundances of the related element. ChemCam is sensitive to most major rock-forming elements as well as to a set of minor and trace elements such as F, Cl, Li, P, Sr, Ba, and Rb. The measured chemical composition can then be used to infer the mineralogical composition of the ablated material. Here, we report a summary of inferred apatite detections along the MSL traverse at Gale Crater. We present the geologic settings of these findings and derive some interpretations about the formation conditions of apatite in time and space

Renewed global partnerships and redesigned roadmaps for rabies prevention and control

Canine rabies, responsible for most human rabies deaths, is a serious global public health concern. This zoonosis is entirely preventable, but by focusing solely upon rabies prevention in humans, this "incurable wound" persists at high costs. Although preventing human deaths through canine rabies elimination is feasible, dog rabies control is often neglected, because dogs are not considered typical economic commodities by the animal health sector. Here, we demonstrate that the responsibility of managing rabies falls upon multiple sectors, that a truly integrated approach is the key to rabies elimination, and that considerable progress has been made to this effect. Achievements include the construction of global rabies networks and organizational partnerships; development of road maps, operational toolkits, and a blueprint for rabies prevention and control; and opportunities for scaling up and replication of successful programs. Progress must continue towards overcoming the remaining challenges preventing the ultimate goal of rabies elimination

Points to consider in ethically constructing patient-controlled electronic health records

Patient advocates and leaders in informatics have long proposed that patients should have greater ability to control the information in their electronic health record (EHR), including how it can be accessed by their health care providers. The value of such “granular” control, as it has been termed, has been supported prominently in an influential report by the President’s Council of Advisors on Science and Technology (PCAST). Recently, the U.S. Department of Health and Human Services (HHS) Office of the National Coordinator for Health Information Technology (ONC) funded several projects to study key components of EHR systems, including exploring ways to allow granular control. This “Points to Consider” document provides an overview of the benefits, risks and challenges of granular control of EHRs; a review of the key ethical principles, values, and Fair Information Practices that ought to guide development of an EHR that accommodates granular control, and seven detailed Points to Consider to guide decision making.Award No: 90HT0054/01, a cooperative agreement program from the US Department of Health and Human Services, Office of the National Coordinator for Health IT to Indiana Health Information Technology, Inc.

Pulsed-field magnetization of drilled bulk high-temperature superconductors: flux front propagation in the volume and on the surface

We present a method for characterizing the propagation of the magnetic flux in an artificially drilled bulk high-temperature superconductor (HTS) during a pulsed-field magnetization. As the magnetic pulse penetrates the cylindrical sample, the magnetic flux density is measured simultaneously in 16 holes by means of microcoils that are placed across the median plane, i.e. at an equal distance from the top and bottom surfaces, and close to the surface of the sample. We discuss the time evolution of the magnetic flux density in the holes during a pulse and measure the time taken by the external magnetic flux to reach each hole. Our data show that the flux front moves faster in the median plane than on the surface when penetrating the sample edge; it then proceeds faster along the surface than in the bulk as it penetrates the sample further. Once the pulse is over, the trapped flux density inside the central hole is found to be about twice as large in the median plane than on the surface. This ratio is confirmed by modelling

Theory of a quodon gas. With application to precipitation kinetics in solids under irradiation

Rate theory of the radiation-induced precipitation in solids is modified with account of non-equilibrium fluctuations driven by the gas of lattice solitons (a.k.a. quodons) produced by irradiation. According to quantitative estimations, a steady-state density of the quodon gas under sufficiently intense irradiation can be as high as the density of phonon gas. The quodon gas may be a powerful driver of the chemical reaction rates under irradiation, the strength of which exponentially increases with irradiation flux and may be comparable with strength of the phonon gas that exponentially increases with temperature. The modified rate theory is applied to modelling of copper precipitation in FeCu binary alloys under electron irradiation. In contrast to the classical rate theory, which disagrees strongly with experimental data on all precipitation parameters, the modified rate theory describes quite well both the evolution of precipitates and the matrix concentration of copper measured by different methodsComment: V.
