    Objective To examine the association between sociodemographic factors, sexual behaviors, and social factors on potential uptake of PrEP among African-American and White adult women in the United States. Methods Participants were recruited through a nationally representative random-digit dial telephone household survey. Participants comprised a nationally representative random sample of unmarried African-American (N=1068) and White women (N=441) aged 20–44. Interviews were conducted using computer-assisted telephone interviewing technology. Bivariate and multivariate analyses examined the relationship between sociodemographics, sexual behaviors, and social influences on women’s potential uptake of PrEP. Results In multivariate analyses, women with lower educational status, greater lifetime sexual partners, provider recommendations supportive of PrEP, and peer norms supportive of PrEP use were more likely to report potential PrEP uptake. Racial analyses revealed that compared to White women, African-American women were significantly more likely to report potential use of PrEP (aOR=1.76; p ≤ 0.001), more likely to report use PrEP if recommended by a healthcare provider (aOR=1.65; p≤0.001), less likely to report that they would be embarrassed to ask a healthcare provider for PrEP (aOR=0.59; p ≤ 0.05) and more likely to report use of PrEP if their female friends also used PrEP (aOR=2.2; p ≤ 0.001). The potential cost for PrEP was identified as a barrier to adoption by both African-American and White women. Conclusions Findings suggest that women at increased risk for HIV, including those with less education and greater number of sexual partners, may be more likely to use PrEP, although cost may serve as a barrier.

    2008-01-01

    Objective Prep1 and Pbx2 are the main homeodomain DNA-binding proteins of the TALE (three amino acid loop extension) family expressed in the thymus. We previously reported reduced Pbx2 expression and defective thymocyte maturation in Prep1 hypomorphic mice. To further investigate the role of this homeodomain DNA-binding protein in T cell development, we generated transgenic mice expressing the N-terminal fragment of Pbx1 (Pbx1NT) under the control of the Lck proximal promoter. Principal Findings Pbx1NT causes Prep1 cytosolic sequestration, abolishes Prep1-dependent DNA-binding activity and results in reduced Pbx2 expression in developing thymocytes. Transgenic thymi reveal increased numbers of CD4− CD8− CD44− (DN3 and DN4) thymocytes, due to a higher frequency of DN2 and DN4 Pbx1NT thymocytes in the S phase. Transgenic thymocytes however do not accumulate at later stages, as revealed by a normal representation of CD4/CD8 double positive and single positive thymocytes, due to a higher rate of apoptotic cell death of DN4 Pbx1NT thymocytes. Conclusion The results obtained by genetic (Prep1 hypomorphic) and functional (Pbx1NT transgenic) inactivation of Prep1 support nonredundant roles for this homeodomain protein during different stages of T cell development.

    2016-01-01

    Objectives As trials were assessing the safety and efficacy of daily oral antiretroviral preexposure prophylaxis (PrEP) for the prevention of HIV infection, there was a clear need to understand the evolution of knowledge of, and attitudes toward, PrEP among primary care clinicians. Methods Physicians and nurse practitioners were surveyed in 2009 (n = 1500), 2010 (n = 1504), 2012 (n = 1503), 2013 (n = 1507), 2014 (n = 1508) and 2015 (n = 1501) to assess their awareness of PrEP, willingness to prescribe PrEP, and whether they support use of public funds to pay for PrEP. Pharmacists (n = 251) were surveyed about PrEP in 2012 only. Descriptive statistics were computed for physician demographics and PrEP-related questions. Prevalence ratios for willingness to prescribe PrEP were computed using Poisson regression analysis. Results Awareness of PrEP was low among clinicians (2009: 24%, 2010: 29%) but increased after trials reported effectiveness (2012: 49%, 2013: 51%, 2014: 61%, 2015: 66%). Following a description of PrEP with an estimated effectiveness of 75%, across 6 of the study years 91% of clinicians indicated a willingness to prescribe PrEP to at least one group at high risk of HIV acquisition. A smaller majority of clinicians indicated support for public funding of PrEP in 2009: 59%, 2010: 53%, and 2013: 63%. Conclusions In surveys conducted before and after the release of PrEP trial results, primary care clinicians were largely unaware of PrEP. They indicated high levels of willingness to prescribe it for patients at high risk of HIV acquisition and expressed interest in education about how to deliver this new clinical HIV prevention method. It will be important to continue monitoring clinician knowledge, attitudes, and practices as the use of PrEP increases in the US. PMID:27258374

    Introduction Pre-exposure prophylaxis (PrEP) is a promising approach to reducing HIV incidence. Thus garnering the support of HIV providers, who are most familiar with antiretrovirals and likely to encounter patients in HIV serodiscordant relationships, to scale-up PrEP implementation is essential. We sought to determine whether certain subgroups of HIV providers were more likely to intend to prescribe PrEP. Methods Surveys were administered to HIV providers in Miami, Florida and Washington, DC. Composite scores were developed to measure PrEP knowledge, experience, and likelihood of prescribing. Latent class analysis (LCA) was used to stratify provider attitudes toward PrEP. Results Among 142 HIV providers, 73.2% had cared for more than 20 HIV-infected patients in the prior 3 months; 17% had ever prescribed PrEP. LCA identified two classes of providers (entropy 0.904); Class 1 (n=95) found PrEP less effective and perceived barriers to prescribing it; Class 2 (n=47) perceived PrEP as moderately effective and perceived fewer barriers to prescribing it. Compared to Class 2, Class 1 had significantly less experience with PrEP delivery (t(22.7)=2.88, p=0.009) and was significantly less likely to intend to prescribe to patients with multiple sex partners (20% vs. 43%, p=0.04) and those with a drug use history (7% vs. 24%, p=0.001). Conclusions While most HIV providers found PrEP to be effective, those considering it less effective had limited knowledge and experience with PrEP and had lesser intentions to prescribe. Provider training regarding whom should receive PrEP and addressing potential barriers to PrEP provision are needed if this HIV prevention method is to be optimized. PMID:26247895

  14. Current Concepts for PrEP Adherence

    PubMed Central

    Haberer, Jessica E.

    2016-01-01

    Purpose of review This review describes 1) the current understanding of adherence to oral PrEP, 2) methods for adherence measurement, 3) approaches to supporting PrEP adherence, and 4) guidance for defining PrEP adherence goals within the larger context of HIV prevention. Recent findings PrEP adherence has generally been higher in recent trials, open-label extensions, and demonstration projects compared to the initial clinical trials; potential explanations include known PrEP efficacy and different motivations to take PrEP. Recent studies have explored adherence monitoring through electronic pill containers, short message service (SMS), and drug concentrations in hair and dried blood spots. The few PrEP adherence interventions developed to date include combinations of enhanced counseling, feedback of objective adherence measurement, and SMS. Conceptualization of PrEP adherence is evolving. The goal is not 100% adherence indefinitely, as it was in clinical trials. PrEP adherence should be defined with respect to HIV exposure, which varies over time by sexual behavior and use of other prevention strategies. Summary PrEP adherence beyond clinical trials has generally been high enough to achieve reliable HIV prevention. Future efforts to measure and support PrEP adherence should focus on the context of risk for HIV acquisition, accounting for dynamic behaviors and choices among HIV prevention options. PMID:26633638

    Chemical synthesis methods are being developed as a future source of PZT 95/5 powder for neutron generator voltage bar applications. Laboratory-scale powder processes were established to produce PZT billets from these powders. The interactions between calcining temperature, sintering temperature, and pore former content were studied to identify the conditions necessary to produce PZT billets of the desired density and grain size. Several binder systems and pressing aids were evaluated for producing uniform sintered billets with low open porosity. The development of these processes supported the powder synthesis efforts and enabled comparisons between different chem-prep routes.

  2. PrEP: controversy, agency and ownership

    Cairns, Gus P; Race, Kane; Goicochea, Pedro

    2016-01-01

    Pre-exposure prophylaxis (PrEP) has been and continues to be an intervention that causes controversy and debate between stakeholders involved in providing or advocating for it, and within communities in need of it. These controversies extend beyond the intrinsically complex issues of making it available. In this commentary, some of the possible roots of the air of dissent and drama that accompanies PrEP are explored. The similarities between the controversies that dogged the earliest human trials of PrEP and the ones we see today in the era of licensing and implementation are explored. We outline five mediating principles or cultural norms that may influence arguments about PrEP differently. Three areas of specific concern are identified: medical risk versus benefit, distrust and fear of healthcare interventions, and fears for individual responsibility and community cohesion. The fear that PrEP may somehow represent a loss of control over one or more of these domains is suggested as an underlying factor. The development of countervailing measures, to institute greater community “ownership” of PrEP, and concomitant improvements in the sense of individual agency over sexual risk are outlined and recommended.

    PubMed

    Gordon, Jeffry S; McNew, Ryan

    2008-12-01

    Institutions of higher education are now using Internet-based technology tools to conduct surveys for data collection. Research shows that the type and quality of responses one receives with online surveys are comparable with what one receives in paper-based surveys. Data collection can take place on Web-based surveys, e-mail-based surveys, and personal digital assistants/Smartphone devices. Web surveys can be subscription templates, software packages installed on one's own server, or created from scratch using Web programming development tools. All of these approaches have their advantages and disadvantages. The survey owner must make informed decisions as to the right technology to implement. The correct choice can save hours of work in sorting, organizing, and analyzing data.

  8. The Role of Healthcare Providers in the Roll-Out of PrEP

    PubMed Central

    Krakower, Douglas S.; Mayer, Kenneth H.

    2015-01-01

    Purpose of Review To review the most recent studies assessing the preparedness of healthcare practitioners to provide anti-HIV pre-exposure prophylaxis (PrEP) and to suggest areas for future implementation research. Recent Findings As PrEP is a bio-behavioral intervention, healthcare providers are likely to play a critical role in implementing PrEP in care settings. Studies suggest that many specialized providers are aware of PrEP and support its provision as a public health intervention, though knowledge and acceptance are less among generalists. Therefore, utilization of PrEP by clinicians has been limited to a few early adopters. Concerns about the efficacy and long-term safety of PrEP, and perceived barriers to prescribing PrEP, could limit prescribing behaviors and intentions. Resistance to performing routine HIV risk assessments by clinicians is an additional barrier to implementing PrEP, though innovative tools to help clinicians routinely perform risk assessments are being developed. Summary Interventions are needed to engage a broader array of healthcare providers in PrEP provision. Utilizing a framework based on diffusion of innovation theory, this review proposes strategies that can be implemented and evaluated to increase PrEP prescribing by healthcare providers. If resources are invested in training clinicians to provide PrEP, then these stakeholders could enhance the use of PrEP as part of a prevention package by primary providers. PMID:26417953

    2017-01-01

    PREP1 and PBX1 are homeodomain (HD) transcription factors that play crucial roles in embryonic development. Here, we present the first biophysical characterization of a PREP1 HD, and the NMR spectroscopic study of its DNA binding pocket. The data show that residues flanking the HD participate in DNA binding. The kinetic parameters for DNA binding of individual PREP1 and PBX1 HDs, and of their combination, show that isolated PREP1 and PBX1 HDs bind to DNA in a cooperative manner. A novel PREP1 motif, flanking the HD at the C-terminus, is required for cooperativity. PMID:28094776

    1986-01-01

    The State of Hawaii has conducted several surveys on public opinion towards the development of geothermal energy. The latest poll was designed to: measure public opinion in the County of Hawaii relevant to geothermal development for electrical power supplied to Island of Hawaii residents only; measure public opinion in the County of Hawaii relevant to geothermal development of electricity to be exported for use on Oahu; and identify barriers to, and opportunities for energy conservation programs, including geothermal development. In general, the residents of the County of Hawaii favor some form of geothermal development. Issues on geothermal development of concern to the public were similar to those mentioned in the 1982 study. Basically, the issues amount to a trade-off between the economic advantages and the environmental problems of geothermal development. The strong points in favor of development include a perceived need for more energy, a strong preference for alternate energy forms over petroleum, perceived benefits for the local economy and the employment rates, and the possibility that development may reduce or contain utility bills. On the other hand, it appears that geothermal development will cause health problems for those who live near the wells, be hazardous to flora and fauna in the Puna area, and create noise and odor above tolerable levels. These are oversimplified statements of the reasons behind both support and opposition for geothermal development.

  3. NEXT GENERATION ORAL PrEP: BEYOND TENOFOVIR

    PubMed Central

    Abraham, Bisrat K.; Gulick, Roy

    2013-01-01

    Purpose Clinical trials of oral pre-exposure prophylaxis (PrEP) have focused testing on regimens of tenofovir (TDF) with or without emtricitabine (FTC). However, TDF may be associated with toxicities (renal, bone) and FTC may select for drug resistance. In this review, we discuss agents that might serve as alternatives to TDF/FTC for HIV prevention. Recent Findings Several drug characteristics are important to consider when selecting agents for PrEP with the most critical being safety, tolerability, adequate penetration into target tissues, prevention of HIV infection, and long lasting activity with convenient dosing. With these factors in mind, we review several potentially useful agents for PrEP. The first group includes drugs that are already FDA-approved (maraviroc, raltegravir) with attributes that make them attractive for PrEP. The second groups of drugs include investigational agents with long-lasting activities that are being developed in parenteral form (rilpivirine-long acting, S/GSK 1265744, ibalizumab). Summary Current research suggests there will be a broader array of PrEP drugs to choose from in the near future, thereby giving clinicians the flexibility to select agents that best suit the needs of their patient population.

    Abstract Pre-exposure prophylaxis (PrEP) for HIV-uninfected persons is highly efficacious for HIV prevention. Understanding how people at risk for HIV will use PrEP is important to inform PrEP scale-up and implementation. We used qualitative methods to gather insights into couples' early experiences with PrEP use within the Partners Demonstration Project, an open-label implementation study evaluating integrated delivery of PrEP and antiretroviral therapy (ART). PrEP is offered to HIV uninfected partners until the HIV-infected partner initiates and sustains ART use (i.e., PrEP as a “bridge” to ART initiation and viral suppression). From August 2013 to March 2014 we conducted 20 in-depth dyadic interviews (n = 40) with heterosexual HIV serodiscordant couples participating at the Thika, Kenya study site, exploring how couples make decisions about using PrEP for HIV prevention. We developed and applied deductive and inductive codes to identify key themes related to experiences of PrEP initiation and use of time-limited PrEP. Couples reported that PrEP offered them an additional strategy to reduce the risk of HIV transmission, meet their fertility desires, and cope with HIV serodiscordance. Remaining HIV negative at follow-up visits reinforced couples' decisions and motivated continued adherence to PrEP. In addition, confidence in their provider's advice and client-friendly services were critical to their decisions to initiate and continue use of PrEP. Strategies for wide-scale PrEP delivery for HIV serodiscordant couples in low resource settings may include building capacity of health providers to counsel on PrEP adoption while addressing couples' concerns and barriers to adoption and continued use.

  9. From modeling to morals: imagining the future of HIV PREP in Lesotho.

    2013-08-01

    Amidst growing global endorsements of new biomedical HIV prevention strategies, ARV-based pre-exposure prophylaxis (ARV PrEP) has garnered considerable attention as a potentially promising prevention strategy. Though it may offer more effective protection for certain at-risk groups than conventional prevention strategies (such as sexual partner reduction, condom use, and prevention of mother-to-child transmission), PrEP is more costly. PrEP requires more ongoing contact between individuals and providers, and a level of surveillance from the health system that is not necessary with other preventive measures. In this sense, it represents a new bio-technology for HIV prevention that poses particular challenges for worldwide implementation, given developing countries' struggling health systems and incomplete HIV treatment programs. Since the emergence of PrEP has stimulated ethical discussions premised on incomplete knowledge of efficacy and implementation, this paper explores the ethical parameters of a likely scenario for PrEP usage in a single, resource-poor country. We first develop a plausible model for PrEP deployment and utilization based on current PrEP research, while carefully considering the reigning institutional values of feasibility and effectiveness in global health approaches. Drawing on ethnographic research of HIV treatment and prevention approaches in Lesotho, we address ethical questions arising from this scenario of PrEP delivery. Lesotho presents a compelling and emblematic case study of PrEP's potential successes and pitfalls in a developing country, given the country's high HIV prevalence, struggles to achieve universal access to HIV treatment regimes, continued existence of stigma around the epidemic, and difficulties in addressing persistent social inequalities that fuel infections.

    Abstract In the United States, rates of HIV infection are highest among black men who have sex with men (BMSM). Pre-exposure prophylaxis (PrEP) is a highly effective form of HIV prevention, but the uptake of this strategy has been slow since FDA approval in 2012, and it is unknown whether information about PrEP is reaching BMSM. Four hundred and thirty-six BMSM in Atlanta, GA were surveyed from January 2012 (6 months prior to PrEP approval) to March 2014 (20 months after approval). Analyses revealed no association between date of survey assessment and awareness of PrEP (20.5% were aware of PrEP before approval and 23.4% were aware after approval; OR=0.99 [0.98–1.02], p=0.952). In a multivariate model, BMSM unaware of PrEP reported lower rates of HIV testing knowledge, fewer experiences with HIV testing, and higher rates of transactional sex than BMSM who were aware of PrEP. Our findings suggest that there is limited understanding of PrEP and that there is considerable groundwork that needs to be achieved in order to reap the full benefits of PrEP. The current findings call attention to the need to both prioritize and better understand how to strengthen the bridge between medical advances and community uptake. PMID:26083143

  17. Development Paths in Archaeological Surveying

    Tabbagh, A.

    2005-05-01

    Geophysical surveys of archaeological sites began in 1938, when an electrical survey was performed at the historical site of Williamsburg (Virginia, USA). Its full development, however, has been achieved by several European teams, which have continuously worked on it since the fifties. Geophysical survey is one step of archaeological site reconnaissance, which comprises many other non-invasive techniques such as document studies, field walking, air photo interpretation...Nevertheless solely geophysical techniques allow a direct exploration of the underground itself over a significant depth of investigation. Several physical properties can be measured to detect and map archaeological features and/or remains but electrical resistivity and magnetisation has been commonly used for fifty years and dielectric permittivity more recently. The major path of the technical evolution was to increase both the speed of the survey and the size of the area by using short measurement duration (less than 0.1 s) and to incorporate mechanical systems that allow the continuous pulling of the sensors on the field. Magnetic measurements are thus achieved either by fluxgate or optically pumped sensors, while electrical measurements are achieved by mobile multi-pole systems simultaneously over two or three different depths. In such surveys the mesh grid is 1 x 1 m or 0.5 x 0.5 m. Another aim is to limit the size of the surveyed area but to increase the geometrical resolution by using ground penetrating radars (GPR) with a very fine mesh (0.2 x 0.2 m) and by processing the data by `time slices' which allow to follow precisely the extension in depth of the different features. In addition for magnetic features, the simultaneous inversion of magnetic field and susceptibility (and soon viscosity) measurements using linear filtering allows the differentiation among the types of magnetization and allows for an improved determination of the depths of magnetic property contrasts. By considering the

    2016-01-01

    Background Recent clinical trials suggest that pre-exposure prophylaxis (PrEP) may reduce HIV transmission by up to 86% for men who have sex with men (MSM), whilst relatively high levels of PrEP acceptability have been reported to date. This study examines PrEP awareness amongst sub-groups of MSM communities and acceptability amongst MSM in a low prevalence region (Scotland, UK), using a mixed methods design. Methods Quantitative surveys of n = 690 MSM recruited online via social and sociosexual media were analysed using descriptive statistics and multivariate logistic regression. In addition, n = 10 in-depth qualitative interviews with MSM were analysed thematically. Results Under one third (29.7%) of MSM had heard of PrEP, with awareness related to living in large cities, degree level education, commercial gay scene use and reporting an HIV test in the last year. Just under half of participants (47.8%) were likely to use PrEP if it were available but there was no relationship between PrEP acceptability and previous PrEP awareness. Younger men (18–25 years) and those who report higher risk UAI were significantly more likely to say they would use PrEP. Qualitative data described specific PrEP scenarios, illustrating how risk, patterns of sexual practice and social relationships could affect motivation for and nature of PrEP use. Conclusion These findings suggest substantial interest PrEP amongst MSM reporting HIV risk behaviours in Scotland. Given the Proud results, there is a strong case to investigate PrEP implementation within the UK. However, it appears that disparities in awareness have already emerged along traditional indicators of inequality. Our research identifies the need for comprehensive support when PrEP is introduced, including a key online component, to ensure equity of awareness across diverse MSM communities (e.g. by geography, education, gay scene use and HIV proximity), as well as to responding to the diverse informational and sexual health

    Strategic framing of public messages about HIV pre-exposure prophylaxis (PrEP) may influence public support for policies and programs affecting access. This survey study examined how public attitudes toward PrEP differed based on the social group PrEP was described as benefiting ("beneficiary") and the moderating effect of prejudice. Members of the general public (n = 154) recruited online were randomly assigned to three beneficiary conditions: general population, gay men, or Black gay men. All participants received identical PrEP background information before completing measures of PrEP attitudes (specifying beneficiary), racism, and heterosexism. Despite anticipating greater PrEP adherence among gay men and Black gay men and perceiving PrEP as especially beneficial to the latter, participants expressed lower support for policies/programs making PrEP affordable for these groups vs. the general population. This disparity in support was stronger among participants reporting greater prejudice. Inclusive framing of PrEP in public discourse may prevent prejudice from undermining implementation efforts.

    Pre-B-cell leukemia homeobox (Pbx)-regulating protein-1 (Prep1) is a ubiquitous homeoprotein involved in early development, genomic stability, insulin sensitivity, and hematopoiesis. Previously we have shown that Prep1 is a haploinsufficient tumor suppressor that inhibits neoplastic transformation by competing with myeloid ecotropic integration site 1 for binding to the common heterodimeric partner Pbx1. Epithelial-mesenchymal transition (EMT) is controlled by complex networks of proinvasive transcription factors responsive to paracrine factors such as TGF-β. Here we show that, in addition to inhibiting primary tumor growth, PREP1 is a novel EMT inducer and prometastatic transcription factor. In human non-small cell lung cancer (NSCLC) cells, PREP1 overexpression is sufficient to trigger EMT, whereas PREP1 down-regulation inhibits the induction of EMT in response to TGF-β. PREP1 modulates the cellular sensitivity to TGF-β by inducing the small mothers against decapentaplegic homolog 3 (SMAD3) nuclear translocation through mechanisms dependent, at least in part, on PREP1-mediated transactivation of a regulatory element in the SMAD3 first intron. Along with the stabilization and accumulation of PBX1, PREP1 induces the expression of multiple activator protein 1 components including the proinvasive Fos-related antigen 1 (FRA-1) oncoprotein. Both FRA-1 and PBX1 are required for the mesenchymal changes triggered by PREP1 in lung tumor cells. Finally, we show that the PREP1-induced mesenchymal transformation correlates with significantly increased lung colonization by cells overexpressing PREP1. Accordingly, we have detected PREP1 accumulation in a large number of human brain metastases of various solid tumors, including NSCLC. These findings point to a novel role of the PREP1 homeoprotein in the control of the TGF-β pathway, EMT, and metastasis in NSCLC.

    TALE (three amino acids loop extension) homeodomain transcription factors are required in various steps of embryo development, in many adult physiological functions, and are involved in important pathologies. This review focuses on the PREP, MEIS, and PBX sub-families of TALE factors and aims at giving information on their biochemical properties, i.e., structure, interactors, and interaction surfaces. Members of the three sets of protein form dimers in which the common partner is PBX but they can also directly interact with other proteins forming higher-order complexes, in particular HOX. Finally, recent advances in determining the genome-wide DNA-binding sites of PREP1, MEIS1, and PBX1, and their partial correspondence with the binding sites of some HOX proteins, are reviewed. These studies have generated a few general rules that can be applied to all members of the three gene families. PREP and MEIS recognize slightly different consensus sequences: PREP prefers to bind to promoters and to have PBX as a DNA-binding partner; MEIS prefers HOX as partner, and both PREP and MEIS drive PBX to their own binding sites. This outlines the clear individuality of the PREP and MEIS proteins, the former mostly devoted to basic cellular functions, the latter more to developmental functions.

    Background Daily pre-exposure prophylaxis (PrEP) is an effective HIV prevention strategy, but adherence is required for maximum benefit. To date, there are no empirically supported PrEP adherence interventions. This manuscript describes the process of developing a PrEP adherence intervention and presents results on its impact on adherence. Methods The Partners PrEP Study was a placebo-controlled efficacy trial of daily oral tenofovir and emtricitabine/tenofovir PrEP among uninfected members of HIV serodiscordant couples. An ancillary adherence study was conducted at three study sites in Uganda. Participants with <80% adherence as measured by unannounced pill count received an additional adherence counseling intervention based on Lifesteps, an evidence-based HIV treatment adherence intervention, based on principles of cognitive-behavioral theory. Findings Of the 1,147 HIV seronegative participants were enrolled in the ancillary adherence study, 168 (14.6%) triggered the adherence intervention. Of participants triggering the intervention, 62% were male; median age was 32.5 years. The median number of adherence counseling sessions was 10. Mean adherence during the month before the intervention was 75.7%, and increased significantly to 84.1% in the month after the first intervention session (p<0.001). The most frequently endorsed adherence barriers at session one were travel and forgetting. Interpretation A PrEP adherence intervention was feasible in a clinical trial of PrEP in Uganda and PrEP adherence increased after the intervention. Future research should identify PrEP users with low adherence for enhanced adherence counseling and determine optimal implementation strategies for interventions to maximize PrEP effectiveness.

    Background Randomized controlled trials reported that pre-exposure prophylaxis (PrEP) with tenofovir and emtricitabine rarely selects for drug resistance. However, drug resistance due to PrEP is not completely understood. In daily practice, PrEP will not be used under the well-controlled conditions available in the trials, suggesting that widespread use of PrEP can result in increased drug resistance. Methods We surveyed expert virologists with questions about biological assumptions regarding drug resistance due to PrEP use. The influence of these assumptions on the prevalence of drug resistance and the fraction of HIV transmitted resistance was studied with a mathematical model. For comparability, 50% PrEP-coverage of and 90% per-act efficacy of PrEP in preventing HIV acquisition are assumed in all simulations. Results Virologists disagreed on the following: the time until resistance emergence (range: 20–180 days) in infected PrEP users with breakthrough HIV infections; the efficacy of PrEP against drug-resistant HIV (25%-90%); and the likelihood of resistance acquisition upon transmission (10%-75%). These differences translate into projections of 0.6%- 1% and 3.5%—6% infected individuals with detectable resistance 10 years after introducing PrEP, assuming 100% and 50% adherence, respectively. The rate of resistance emergence following breakthrough HIV infection and the rate of resistance reversion after PrEP use is discontinued, were the factors identified as most influential on the expected resistance associated with PrEP. Importantly, 17–23% infected individuals could virologically fail treatment as a result of past PrEP use or transmitted resistance to PrEP with moderate adherence. Conclusions There is no broad consensus on quantification of key biological processes that underpin the emergence of PrEP-associated drug resistance. Despite this, the contribution of PrEP use to the prevalence of the detectable drug resistance is expected to be small. However

    Nuclear weapons have been produced in the US since the early 1950s by a network of contractor-operated Department of Energy (DOE) facilities collectively known as the Nuclear Weapon Complex (NWC). Recognizing that the failure of an essential process might stop weapon production for a substantial period of time, the DOE Albuquerque Operations office initiated the Production Risk Evaluation Program (PREP) at Sandia National Laboratories (SNL) to assess quantitatively the potential for serious disruptions in the NWC weapon production process. PREP was conducted from 1984-89. This document is an unclassified summary of the effort.

    With a global estimate of 2.5 million new infections of HIV occurring yearly, discovering novel methods to help stem the spread of the virus is critical. The use of antiretroviral chemoprophylaxis for preventing HIV after accidental or occupational exposure and in maternal to fetal transmission has become a widely accepted method to combat HIV. Based on this success, pre-exposure chemoprophylaxis (PrEP) is being explored in at-risk patient populations such as injecting drug users, female sex workers and men who have sex with men. This off-label and unmonitored use has created a need for education and intervention by pharmacists and other healthcare professionals. Pharmacists should educate themselves on PrEP and be prepared to counsel patients about their means of obtaining it (e.g. borrowing or sharing medications and ordering from disreputable Internet pharmacies). They should also be proactive about medication therapy management in these patients due to clinically important drug interactions with PrEP medications. Only one trial exploring the safety and efficacy of tenofovir as PrEP has been completed thus far. However, five ongoing trials are in various stages and two additional studies are scheduled for the near future. Unfortunately, studies in this arena have met with many challenges that have threatened to derail progress. Ethical controversy surrounding post-trial care of participants who seroconvert during studies, as well as concerns over emerging viral resistance and logistical site problems, have already halted several PrEP trials. Information about these early trials has already filtered down to affected individuals who are experimenting with this unproven therapy as an “evening before pill”. The potential for PrEP is promising; however, more extensive trials are necessary to establish its safety and efficacy.

The potential for PrEP is promising; however, more extensive trials are necessary to establish its safety and efficacy. Pharmacists are well-positioned to play a key role in helping patients make choices about PrEP, managing their therapy, and developing policy

  13. PrEP as a feature in the optimal landscape of combination HIV prevention in sub-Saharan Africa

    Introduction The new WHO guidelines recommend offering pre-exposure prophylaxis (PrEP) to people who are at substantial risk of HIV infection. However, where PrEP should be prioritised, and for which population groups, remains an open question. The HIV landscape in sub-Saharan Africa features limited prevention resources, multiple options for achieving cost saving, and epidemic heterogeneity. This paper examines what role PrEP should play in optimal prevention in this complex and dynamic landscape. Methods We use a model that was previously developed to capture subnational HIV transmission in sub-Saharan Africa. With this model, we can consider how prevention funds could be distributed across and within countries throughout sub-Saharan Africa to enable optimal HIV prevention (that is, avert the greatest number of infections for the lowest cost). Here, we focus on PrEP to elucidate where, and to whom, it would optimally be offered in portfolios of interventions (alongside voluntary medical male circumcision, treatment as prevention, and behaviour change communication). Over a range of continental expenditure levels, we use our model to explore prevention patterns that incorporate PrEP, exclude PrEP, or implement PrEP according to a fixed incidence threshold. Results At low-to-moderate levels of total prevention expenditure, we find that the optimal intervention portfolios would include PrEP in only a few regions and primarily for female sex workers (FSW). Prioritisation of PrEP would expand with increasing total expenditure, such that the optimal prevention portfolios would offer PrEP in more subnational regions and increasingly for men who have sex with men (MSM) and the lower incidence general population. The marginal benefit of including PrEP among the available interventions increases with overall expenditure by up to 14% (relative to excluding PrEP). The minimum baseline incidence for the optimal offer of PrEP declines for all population groups as expenditure

    We sought to determine preferences for oral versus long-acting injectable (LAI) PrEP among gay and bisexual men (GBM). We surveyed a national U.S. sample of 1071 GBM about forms of PrEP. LAI PrEP was found to be acceptable among 43.2 % of men when injected monthly compared with 53.6 % of men when injected every 3 months. When asked to choose between forms of PrEP, 46.0 % preferred LAI, 14.3 % oral, 21.7 % whichever was most effective, 10.1 % had no preference, and 7.8 % would not take PrEP. There were no differences in PrEP preferences by race/ethnicity, income, region of residence, or relationship status. Those unwilling to take PrEP were significantly older than those who preferred LAI PrEP and those who would take either. Those who preferred the most effective form were younger, had less education, and reported more recent club drug use. Those who reported condomless anal sex and those who thought they were good PrEP candidates were more willing to take PrEP. Long-term health and side effects were of the greatest concern for both LAI and oral PrEP. The availability of LAI PrEP has the potential to increase uptake among GBM. The results of ongoing clinical trials of LAI PrEP will need to demonstrate similar or greater efficacy as daily Truvada for uptake to be maximized.

    Although preliminary studies showed that preexposure prophylaxis (PrEP) lowers the HIV transmission in individuals with HIV, confirmative trials are ongoing and PrEP is not routinely recommended. The aim of this study was to assess whether individuals with HIV share antiretroviral (ARV) drugs for PrEP and to describe awareness and discussion on PrEP in this population. A cross-sectional survey was conducted in France in 23 representative departments of infectious diseases and internal medicine. Physicians administered an anonymous standardized questionnaire to all individuals with HIV receiving ARVs and followed between 24 and 31 October 2011. The questionnaire included items regarding PrEP (awareness; discussion with their close circle, physician or patients' association; experience), personal sociodemographic characteristics, risk behaviors and HIV status of the participants. Five hundred and ninety three participants were recruited: male 74.2% (men who have sex with men 52.4%, heterosexuals 21.6%), member of patient's association 9.8%. Half of them (50.6%) lived with a stable partner and 35.2% with an HIV-negative partner. Almost half (41.8%) were aware and 29.5% had had discussion about PrEP. In logistic regression, awareness and discussion on PrEP were more frequent: (1) among males, in patients' association members (p< 0.001 for both) and in nonheterosexuals (p=0.023 and 0.057, respectively); (2) among women, in those not living with a stable partner (p=0.035 and p=0.03, respectively) or living with an HIV-negative partner (p=0.049 and p=0.083, respectively). One percent of the participants declared having shared ARVs with someone and 8.3% reported PrEP in their close circle. Men reporting PrEP in their close circle shared ARVs more frequently than those who did not (10.3% vs. 0.2%, p < 0.001). Today, individuals with HIV do not seem to widely share personal ARVs for PrEP with seronegative people. A significant number of individuals with HIV are aware of and

    Introduction Despite progress in scaling up antiretroviral treatment, HIV prevention strategies have not been successful in significantly curbing HIV incidence in Latin America. HIV prevention interventions need to be expanded to target the most affected key populations with a combination approach, including new high impact technologies. Oral pre-exposure prophylaxis (PrEP) is recommended as additional prevention choice for individuals at higher risk of infection and could become a cost-effective prevention tool. We discuss the barriers and solutions for a fair consideration of PrEP as part of combination HIV prevention strategies in Latin America. Discussion Although demonstration projects are ongoing or being planned in a number of countries, to date no Latin American country has implemented a public PrEP programme. The knowledge of policymakers about PrEP implementation needs to be strengthened, and programmatic guidance and cost estimate tools need to be developed to support adequate planning. Despite high levels of awareness among health providers, especially if engaged in HIV or key population care, willingness to prescribe PrEP is still low due to the lack of national policies and guidelines. Key populations, especially men who have sex with men, transgender women and sex workers, have been engaged in demonstration projects, and qualitative research shows high awareness and willingness to use PrEP, especially if accessible in the public sector for free or at affordable price. Concerns of safety, adherence, effectiveness and risk compensation need to be addressed through targeted social communication strategies to improve PrEP knowledge and stimulate demand. Alliance among policymakers, civil society and representatives from key populations, healthcare providers and researchers will be critical for the design and successful implementation of PrEP demonstration projects of locally adapted delivery models. The use of mechanisms of joint negotiation and

    Several potential reduced exposure products (PREPs) for smokeless tobacco (SLT) users are marketed in the United States, though their effects are largely unknown. These products include some that are low in tobacco-specific nitrosamines (TSNs), like Stonewall, a pressed tobacco tablet, and General snus, a moist snuff product produced in Sweden. Methodology assessing the toxicant exposure and effects of cigarette-like PREPs for smokers has been developed, and might be modified for use in evaluating PREPs for SLT users. This report describes two studies examining the toxicant exposure and effects of two PREPs for SLT users. Study 1 (n = 13) consisted of four 4.5-hr laboratory sessions where SLT products (own brand, Stonewall, General snus, and tobacco-free placebo) were used for four 30-min episodes and nicotine exposure and tobacco/nicotine abstinence symptoms were measured. Study 2 (n = 19) consisted of four 5-day ad libitum use periods when participants used own brand, Stonewall, General snus, or no SLT and urinary levels of metabolites of nicotine (cotinine) and the TSN 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNAL) and abstinence symptoms were measured. Compared with own brand, Stonewall was associated with lower levels of cotinine and NNAL, while General snus was associated with similar levels of cotinine and lower levels of NNAL. Abstinence symptoms generally did not differ across tobacco conditions. These results show that clinical laboratory methods can be used to evaluate the toxicant exposure and abstinence symptom suppression associated with PREPs for SLT users.

    ChemPrep was developed to be a stand-alone preparatory short-course to help students succeed in general chemistry. It is Web-based and delivered using the OWL system. Students reported that the ChemPrep materials (short information pages, parameterized questions with detailed feedback, tutorials, and answers to questions through the OWL message system) permitted them to work independently without the need for textbook or lecture. On average, students who completed ChemPrep had higher grades in the subsequent GenChem, Nursing, and Honors chemistry courses, with a greater percentage achieving a grade of C- or higher. Participation in ChemPrep was voluntary, and more women than men responded. Students in the Honors course enrolled in ChemPrep in higher percentages than students in GenChem and Nursing. SAT and departmental math placement exam scores were used as proxy measures of prior achievement and ability. Based on these, Honors chemistry ChemPrep users were on par with their peers but performed better in the course than non-users. In GenChem and Nursing chemistry courses, ChemPrep helped students of high prior achievement and ability perform better than their achievement scores would predict. Weaker or less motivated students did not respond to the voluntary offerings of ChemPrep in the same numbers as stronger or more motivated students, and we are seeking alternate ways to reach this population.

    TALE (three amino acid loop extension) homeodomain proteins include the PBC and the MEINOX sub-families. MEINOX proteins form heterodimer complexes with PBC proteins. Heterodimerization is crucial to DNA binding and for nuclear localization. PBC-MEINOX heterodimers bind DNA also in combination with HOX proteins, thereby modulating their DNA-binding specificity. TALE proteins therefore play crucial roles in multiple developmental and differentiation pathways in vivo. We report the identification and characterization of a novel human gene homologous to PREP1, called PREP2. Sequence comparisons indicate that PREP1 and PREP2 define a novel sub-family of MEINOX proteins, distinct from the MEIS sub-family. PREP2 is expressed in a variety of human adult tissues and displays a more restricted expression pattern than PREP1. PREP2 is capable of heterodimerizing with PBC proteins. Heterodimerization with PBX1 appears to be essential for nuclear localization of both PREP2 and PBX1. A comparison between the functional properties of PREP1 and PREP2 reveals that PREP2-PBX display a faster DNA-dissociation rate than PREP1-PBX heterodimers, suggesting different roles in controlling gene expression. Like PREP1, PREP2-PBX heterodimers are capable of forming ternary complexes with HOXB1. The analysis of some PREP2 in vitro properties suggests a functional diversification among PREP and between PREP and MEIS MEINOX proteins.

    Antiretroviral pre-exposure prophylaxis (PrEP) has received increasing recognition as a viable prescription-based intervention for people at risk for HIV acquisition. However, little is known about racial biases affecting healthcare providers' willingness to prescribe PrEP. This investigation sought to explore medical students' stereotypes about sexual risk compensation among Black versus White men who have sex with men seeking PrEP, and the impact of such stereotypes on willingness to prescribe PrEP. An online survey presented participants (n = 102) with a clinical vignette of a PrEP-seeking, HIV-negative man with an HIV-positive male partner. Patient race was systematically manipulated. Participants reported predictions about patient sexual risk compensation, willingness to prescribe PrEP, and other clinical judgments. Bootstrapping analyses revealed that the Black patient was rated as more likely than the White patient to engage in increased unprotected sex if prescribed PrEP, which, in turn, was associated with reduced willingness to prescribe PrEP to the patient.

    The vulva and vaginal interior are considered a contaminated surgical area, and current OR guidelines require surgeons who are gloved and gowned at the abdominal field to avoid contact with the urethral catheter, the uterine manipulator, and the introitus or to change their gloves and even regown if contact occurs. It is our belief that the perception of the vaginal field as contaminated reflects a lack of specific standards for the preoperative cleansing of the deeper vagina and a lack of preoperative prep instructions for the combined fields. We developed a comprehensive single-field prep technique designed to improve surgical efficiency and prevent contamination of the sterile field. Combining a methodical scrub, prep, and dwell, this technique allows the entire abdomino-perineovaginal field to be treated as a single sterile field for laparoscopic procedures. Our surgical site infection rate of 1.8% when using this single-field prep technique and the subsequent surgical treatment of the abdominal, vaginal, and perineal fields as a single sterile field is well within reported norms.

    Background The combination of tenofovir and emtricitabine (TDF/FTC) shows promise as HIV pre-exposure prophylaxis (PrEP). We sought to forecast clinical, epidemiologic, and economic outcomes of PrEP, taking into account uncertainties regarding efficacy, risk of resistance and toxicity, behavioral disinhibition, and drug costs. Methods We adapted a computer simulation of HIV acquisition, detection, and care to model PrEP in high-risk (1.6% average annual HIV incidence) men who have sex with men (MSM) in the United States. Base case assumptions included: 50% PrEP efficacy and $753 monthly TDF/FTC costs. We used sensitivity analyses to examine the stability of results and to identify critical input parameters. Results In a cohort with mean age 34 years, PrEP reduced lifetime HIV infection risk from 44% to 25% and increased average life expectancy from 39.9 to 40.7 years (21.7 to 22.2 discounted, quality-adjusted life-years or QALYs). Discounted mean lifetime treatment costs increased from $81,100 to $232,700 per person, indicating an incremental cost-effectiveness ratio (ICER) of $298,000 per QALY gained. Markedly larger reductions in lifetime infection risk (from 43.5% to 5.8%) were observed assuming greater (90%) PrEP efficacy. More favorable ICERs were obtained by targeting younger, higher-incidence populations and with improvements in the efficacy and cost of PrEP. Conclusions PrEP could substantially reduce HIV transmission in high-risk populations in the United States. Although it is unlikely to confer sufficient benefits to justify current TDF/FTC costs, price reductions and/or increases in efficacy could make PrEP a cost-effective option in younger or higher-risk populations. Given recent disappointments in HIV prevention and vaccine development, further study of PrEP-based HIV prevention is warranted. PMID:19193111

    We developed methods to monitor the status of Gyrfalcons in Alaska. Results of surveys and monitoring will be informative for resource managers and will be useful for studying potential changes in ecological communities of the high latitudes. We estimated that the probability of detecting a Gyrfalcon at an occupied nest site was between 64% and 87% depending on observer experience and aircraft type (fixed-wing or helicopter). The probability of detection is an important factor for estimating occupancy of nesting areas, and occupancy can be used as a metric for monitoring species' status. We conclude that surveys of nesting habitat to monitor occupancy during the breeding season are practical because of the high probability of seeing a Gyrfalcon from aircraft. Aerial surveys are effective for searching sample plots or index areas in the expanse of the Alaskan terrain. Furthermore, several species of cliff-nesting birds can be surveyed concurrently from aircraft. Occupancy estimation also can be applied using data from other field search methods (e.g., from boats) that have proven useful in Alaska. We believe a coordinated broad-scale, inter-agency, collaborative approach is necessary in Alaska. Monitoring can be facilitated by collating and archiving each set of results in a secure universal repository to allow for statewide meta-analysis.

    Abstract Prior to issuing formal HIV pre-exposure prophylaxis (PrEP) clinical practice guidelines in 2014, the US Centers for Disease Control and Prevention (CDC) had released interim guidance for oral PrEP use among adults. Because oral PrEP may be used off-label for youth and may soon be indicated for minor adolescents, we examined the potential adoption of the interim guidance among clinicians who care for HIV-infected and at-risk youth. Individual, semi-structured interviews were conducted with 15 US clinicians who were recruited through an adolescent HIV research network. The theory-driven interview guide, consisting primarily of open-ended questions, assessed demographics, familiarity with the guidance, attitudes toward the guidance, and attitudes toward the use of the guidance for adult and adolescent patients. Transcripts were analyzed using framework analysis. Most clinicians (11/15) reported that the guidance was compatible with their practice, although several reported that some aspects, particularly frequency of follow-up visits, needed to be tailored to meet their patients' needs. We found variability in clinician reported characteristics of appropriate PrEP candidates (e.g., youth with substance use and mental health issues were noted to be both suitable and unsuitable PrEP candidates) and PrEP use in serodiscordant couples (e.g., whether PrEP would be recommended to a patient whose HIV-infected partner is virally suppressed). Clinician reported steps for initiation, monitoring, and discontinuing PrEP were largely consistent with the guidance. The observed variability in clinician practice with regard to oral PrEP may be reduced through interventions to educate clinicians about the content and rationale for guideline recommendations.

    Introduction Of the two million new HIV infections in adults in 2014, 70% occurred in sub-Saharan Africa. Several African countries have already approved guidelines for pre-exposure prophylaxis (PrEP) for individuals at substantial risk of HIV as part of combination HIV prevention but key questions remain about how to identify and deliver PrEP to those at greatest need. Throughout the continent, individuals in sero-discordant relationships, and members of key populations (sex workers, men who have sex with men (MSM), transgender women and injection drug users) are likely to benefit from the availability of PrEP. In addition, adolescent girls and young women (AGYW) are at substantial risk in some parts of the continent. It has been estimated that at least three million individuals in Africa are likely to be eligible for PrEP according to WHO's criteria. Tens of demonstration projects are planned or underway across the continent among a range of countries, populations and delivery settings. Discussion In each of the target populations, there are overarching issues related to (i) creating demand for PrEP, (ii) addressing supply-side issues and (iii) providing appropriate and tailored adherence support. Critical for creating demand for PrEP is the normalization of HIV prevention. Community-level interventions which engage opinion leaders as well as empowerment interventions for those at highest risk will be key. Critical to supply of PrEP is that services are accessible for all, including for stigmatized populations. Establishing accessible integrated services provides the opportunity to address other public health priorities including the unmet need for HIV testing, contraception and sexually transmitted infections treatment. National policies need to include minimum standards for training and quality assurance for PrEP implementation and to address supply chain issues. Adherence support needs to recognize that social and structural factors are likely to have an

    Introduction Adolescents and young adults aged <25 are a key population in the HIV epidemic, with very high HIV incidence rates in many geographic settings and a large number who have limited access to prevention services. Thus, any biomedical HIV prevention approach should prepare licensure and implementation strategies for young populations. Oral pre-exposure prophylaxis (PrEP) is the first antiretroviral-based prevention intervention with proven efficacy across many settings and populations, and regulatory and policy approvals at global and national levels are occurring rapidly. We discuss available data from studies in the United States and South Africa on the use of oral PrEP for HIV prevention in adolescent minors, along with some of the implementation challenges. Discussion Ongoing studies in the United States and South Africa among youth under the age of 18 should provide the safety data needed by the end of 2016 to contribute to licensure of Truvada as daily PrEP in adolescents. The challenges of completing these studies as well as foreseeable broader challenges highlighted by this work are presented. Adherence to daily PrEP is a greater challenge for younger populations, and poor adherence was associated with decreased efficacy in all PrEP trials. Individual-level barriers include limited familiarity with antiretroviral-based prevention, stigma, product storage, and social support. Structural challenges include healthcare financing for PrEP, clinician acceptability and comfort with PrEP delivery, and the limited youth-friendly health services available. These challenges are discussed in the context of the work done to date in the United States and South Africa, but will likely be magnified in the setting of limited resources in many other countries that are heavily impacted by HIV. Conclusions Adolescent populations are particularly vulnerable to HIV, and oral PrEP in these populations is likely to have an impact on population-level HIV incidence. The

    The development of a geothermal reservoir evaluation method is mentioned for the purpose of reducing the risk of the geothermal development and drawing up an appropriate power generation plan. As for simulators, a geothermal reservoir simulator (SING-I,II) and a geothermal well two-phase simulator (WENG) are developed. For SING-II, an evaluation is made of fracture effects in the pressure interference test, production predicting simulation using fracture models, development of a multicomponent gas-liquid two-phase simulator and a tracer simulation function. As to WENG, verification on fluids containing CO2 and survey on fluids containing NaCl are made. In the Mori area which is a model field, continued observation on reservoir pressure is conducted as well as temperature/pressure logging and chemical analysis of spouted fluids. By three-dimensional grid models of reservoirs, reappearance of natural conditions of temperature/pressure distribution and discharge into the ground surface can roughly be made, and history matching is tried to be made. Newly also in Oguni area, reappearance of natural conditions is simulated using SING-I.

    Pre-exposure prophylaxis (PrEP), taken as a single daily co-formulated pill containing tenofovir-emtricitabine, is a promising intervention to reduce the likelihood of HIV acquisition in at-risk individuals, including men who have sex with men (MSM). Little is known about the acceptability of less than daily, intermittent PrEP (iPrEP) regimens. We conducted an online survey of North American MSM to characterize their sexual frequency and planning behaviors and correlate these with PrEP dosing preferences. Of the 3,217 respondents who completed the survey, 46% reported engaging in unplanned condomless anal intercourse (CAI) at least once in the prior 3 months and 8% reported engaging in CAI more than once per week. In multivariable analysis, reporting unplanned CAI was associated with lower educational level, identifying as homosexual/gay as compared to bisexual, being in a monogamous relationship, having a higher self-perceived risk of HIV acquisition, higher income, engaging in CAI more than five times in the last 3 months, and not having visited a healthcare provider in the previous year. Frequent CAI (>1×/week) was associated with being younger, identifying as homosexual/gay as compared to bisexual, being in a monogamous relationship, and having a higher self-perceived risk of HIV. Having had only planned sex over the last 3 months was associated with a preference for event-based PrEP, while having frequent or unplanned CAI was associated with a preference for daily or time-driven PrEP regimens, respectively. Our findings suggest that preferences for different PrEP regimens are associated with the sexual frequency and planning behaviors of potential users. PMID:26371786

    2011-01-01

    Objective To develop a survey to accurately assess parental vaccine hesitancy. Results The initial survey contained 17 items in four content domains: (1) immunization behavior; (2) beliefs about vaccine safety and efficacy; (3) attitudes about vaccine mandates and exemptions; and (4) trust. Focus group data yielded an additional 10 survey items. Expert review of the survey resulted in the deletion of nine of 27 items and revisions to 11 of the remaining 18 survey items. Parent pretesting resulted in the deletion of one item, the addition of one item, the revision of four items, and formatting changes to enhance usability. The final survey contains 18 items in the original four content domains. Methods An iterative process was used to develop the survey. First, we reviewed previous studies and surveys on parental health beliefs regarding vaccination to develop content domains and draft initial survey items. Focus groups of parents and pediatricians generated additional themes and survey items. Six immunization experts reviewed the items in the resulting draft survey and ranked them on a 1–5 scale for significance in identifying vaccine-hesitant parents (5 indicative of a highly significant item). The lowest third of ranked items were dropped. The revised survey was pretested with 25 parents to assess face validity, usability and item understandability. Conclusions The Parent Attitudes about Childhood Vaccines survey was constructed using qualitative methodology to identify vaccine-hesitant parents and has content and face validity. Further psychometric testing is needed. PMID:21389777

  2. HIV-negative male couples' attitudes about pre-exposure prophylaxis (PrEP) and using PrEP with a sexual agreement.

    2016-08-01

    One efficacious strategy to help prevent HIV is oral pre-exposure prophylaxis (PrEP), a daily regimen of antiretroviral treatment taken by HIV-negative individuals. Two of the recommendations of Centers for Disease Control and Prevention (CDC) guidelines for PrEP pertain to being in a relationship (i.e., male couples). Despite the recognition of how primary partners in male couples' relationships shape HIV risk and CDC's PrEP guidelines, there is a paucity of data that examine HIV-negative male couples' attitudes toward PrEP use and using PrEP with a sexual agreement. A sexual agreement is an explicit agreement made between two individuals about what sex and other related behaviors may occur within and outside of their relationship. In this qualitative study, we examine HIV-negative male couples' attitudes toward PrEP use and whether they thought PrEP could be integrated into a sexual agreement. Data for this study are drawn from couple-level interviews conducted in 2014 with 29 HIV-negative male couples who had a sexual agreement and were from Atlanta or Detroit. Both passive (e.g., flyers) and active (e.g., targeted Facebook advertisements) recruitment methods were used; the sample was stratified by agreement type. Thematic analysis was applied to identify the following themes regarding HIV-negative male couples' attitudes toward PrEP use: (1) PrEP and condom use; (2) concerns about PrEP (e.g., effectiveness, side effects, and promoting sexually risky behavior); and (3) accessibility of PrEP. Some thought PrEP could be a part of couples' agreement because it could help reduce sexual anxiety and sexual risk, and would help keep the couple safe. Others described PrEP use with an agreement as something for "others". Some were also concerned that incorporating PrEP could usurp the need for a sexual agreement in a couples' relationship. These themes highlight the need to improve informational messaging and promotion efforts about PrEP among HIV-negative male couples

    2009-03-01

    Effective planning and response to bioterrorism or other disasters, natural or manmade, requires timely and effective communication as well as situational awareness. During a catastrophic event, decision makers--including first responders, hospital workers, and command center emergency workers--will have a short time to make crucial decisions. Preparing to receive and treat patients, especially when there are mass casualties, requires immediate access to large amounts of integrated health data from disparate sources. This article describes PrepLink, a novel comprehensive web-based healthcare-related all-hazards electronic disaster management system. Over the past 3 years, PrepLink has been developed and tested at the University of Pittsburgh Medical Center in partnership with the Pennsylvania National Guard. It can be deployed in multiple sites across a region or state or more broadly. The system includes pages for public awareness about planning for and responding to disasters, as well as secure, password-protected private pages that can be used by many types of emergency and healthcare personnel who are involved in such events. Timely information related to public health, safety, planning, preparation, and response can be accessed from both sets of pages. The system permits rapid communication and sharing of team plans across disparate locations; it stores multiple key documents and contains asset inventories, a GIS, patient tracking, and a command-and-control module. Each function is directly related to providing healthcare treatment for victims. PrepLink's comprehensive and user friendly approach to health-related disaster management holds promise for future progress in this challenging arena.

  4. PrEP in Europe – expectations, opportunities and barriers

    PubMed Central

    McCormack, Sheena Mary; Noseda, Veronica; Molina, Jean-Michel

    2016-01-01

    Introduction In contrast to the global trend showing a decline in new HIV infections, the number reported in the World Health Organization (WHO) region of Europe is increasing. Health systems are disparate, but even countries with free access to screening and treatment observe continuing high rates of new infections in key populations, notably men who have sex with men (MSM). Pre-exposure prophylaxis (PrEP) is only available in France. This commentary describes the European epidemics and healthcare settings where PrEP could be delivered, how need might be estimated for MSM and the residual barriers to access. Discussion Health systems and government commitment to HIV prevention and care, both financial and political, differ considerably between the countries that make up Europe. A common feature is that funds for prevention are a small fraction of funds for care. Although care is generally good, access is limited in the middle-income countries of Eastern Europe and central Asia, and only 19% of people living with HIV received antiretroviral therapy in 2014. It is challenging to motivate governments or civil society to implement PrEP in the context of this unmet treatment need, which is driven by limited national health budgets and diminishing assistance from foreign aid. The high-income countries of Western Europe have hesitated to embrace PrEP for different reasons, initially due to key gaps in the evidence. Now that PrEP has been shown to be highly effective in European MSM in two randomized controlled trials, it is clear that the major barrier is the cost of the drug which is still on patent, although inadequate health systems and diminishing investment in civil society are also key challenges to overcome. Conclusions The momentum to implement PrEP in European countries is increasing and provides a welcome opportunity to expand and improve clinical services and civil society support focused on HIV and related infections including other sexually transmitted and

    Introduction HIV epidemics in the Asia-Pacific region are concentrated among men who have sex with men (MSM) and other key populations. Pre-exposure prophylaxis (PrEP) is an effective HIV prevention intervention and could be a potential game changer in the region. We discuss the progress towards PrEP implementation in the Asia-Pacific region, including opportunities and barriers. Discussion Awareness about PrEP in the Asia-Pacific is still low and so are its levels of use. A high proportion of MSM who are aware of PrEP are willing to use it. Key PrEP implementation barriers include poor knowledge about PrEP, limited access to PrEP, weak or non-existent HIV prevention programmes for MSM and other key populations, high cost of PrEP, stigma and discrimination against key populations and restrictive laws in some countries. Only several clinical trials, demonstration projects and a few larger-scale implementation studies have been implemented so far in Thailand and Australia. However, novel approaches to PrEP implementation have emerged: researcher-, facility- and community-led models of care, with PrEP services for fee and for free. The WHO consolidated guidelines on HIV testing, treatment and prevention call for an expanded access to PrEP worldwide and have provided guidance on PrEP implementation in the region. Some countries like Australia have released national PrEP guidelines. There are growing community leadership and consultation processes to initiate PrEP implementation in Asia and the Pacific. Conclusions Countries of the Asia-Pacific region will benefit from adding PrEP to their HIV prevention packages, but for many this is a critical step that requires resourcing. Having an impact on the HIV epidemic requires investment. The next years should see the region transitioning from limited PrEP implementation projects to growing access to PrEP and expansion of HIV prevention programmes. PMID:27760688

    Introduction Despite a number of HIV prevention strategies, the number of new HIV infections remains high. In Australia, over three-quarters of new HIV diagnoses are in gay and bisexual men (GBM). Pre-exposure prophylaxis (PrEP) has been shown to be effective at preventing new HIV infections in several randomised trials. The PRELUDE study aims to evaluate the implementation of PrEP in healthcare settings in New South Wales (NSW), Australia, among a sample of high-risk adults. Methods and analysis PRELUDE is an ongoing open-label, single-arm demonstration project, conducted in public and private clinics across NSW, Australia. Enrolment began in November 2014. The study is designed for 300 high-risk participants—mainly GBM and heterosexual women. Participants receive daily oral PrEP, composed of emtricitabine (FTC) and tenofovir disoproxil fumarate (TDF), for up to 2.5 years. Quarterly study visits include testing for HIV and sexually transmitted infections (STIs), assessment of ongoing eligibility and side effects, and self-reported adherence. Following each study visit, online behavioural surveys are administered to collect information on medication adherence, risk behaviours and attitudes. Blood samples will be collected in a subset of patients 1, 6 and 12 months after PrEP initiation to measure FTC/TDF concentrations. Analyses using longitudinal regression models will focus on feasibility, adherence, safety, tolerability and effects of PrEP on behaviour. This study will inform PrEP policy and guide the implementation of PrEP in Australia in people at high risk of HIV. Ethics and dissemination The study will be conducted in accordance with the Declaration of Helsinki. All patients will provide written informed consent prior to participation in the study. Publications relating to each of the primary end points will be gradually released after 12 months of follow-up is complete. Trial registration number NCT02206555; Pre-results. PMID:27324719

    There are few detailed workforce studies of specialty fields within professional psychology, and none have been reported for pediatric psychology since 2006. Availability of such data could facilitate more-informed decision making by students and trainees, psychologists pursuing employment opportunities, and psychologists involved in employment or compensation negotiations. This article describes the work of a task force of the American Psychological Association (APA) Division 54 (Society of Pediatric Psychology) in the design, construction, pretesting, distribution, and data management for the Society of Pediatric Psychology (SPP) Workforce Survey. The 18-member task force was established to design and implement a workforce survey that balanced needs for breadth, clarity, brevity, and protection of confidentiality. The survey solicits information about demographic characteristics; training, licensure and certifications; employment settings, responsibilities, and productivity metrics; compensation; and employment satisfaction. A survey link was distributed via e-mail to full members of the SPP in June 2015. A total of 404 members (32.3% return rate) completed the survey. This article focuses on the development, methodology, and respondent characteristics for this 1st administration of the workforce survey. Separate articles will report detailed analyses of the survey results such as compensation and work satisfaction. Future distributions of the survey will enable compilation of a longitudinal database to track changes in the profession. SPP members and others may propose additional analyses of these data. This work may provide guidance to other groups of specialized psychologists who may wish to implement similar initiatives. PMID:28066693

    Background Recent advances in biomedical prevention strategies, including pre-exposure prophylaxis (PrEP) and achieving an undetectable viral load (UVL) among HIV-infected persons, show promise in curbing the rising incidence of HIV among men who have sex with men (MSM) in the United States. This mixed methods study aimed to investigate the frequency with which MSM encounter potential sex partners on geosocial networking apps who disclose biomedical prevention use, and how MSM make decisions about condom use after these disclosures. Method Participants were recruited via adverstiments placed on a large geosocial networking app for MSM. A total of 668 and 727 participants, respectively, responded to questionnaires assessing partner disclosure of PrEP use and UVL. Each questionnaire included an open-ended item assessing reasons for condomless anal sex (CAS) with partners using biomedical prevention. Results Across both surveys, a majority of respondents encountered potential sex partners who disclosed PrEP use or UVL, and the majority of those who met up with these partners engaged in CAS at least once. Qualitative analyses found that most participants who reported CAS did so after making a calculated risk about HIV transmission. We also describe a novel risk reduction strategy, “biomed-matching,” or having CAS only when both individuals use PrEP or have UVL. We report serostatus differences in both quantitative and qualitative findings. Conclusions Disclosure of PrEP use and UVL is not uncommon among MSM. Many MSM make accurate appraisals of the risks of CAS with biomedical prevention, and mobile apps may aid with disclosing biomedical prevention use. PMID:26761520

    1994-04-01

    The third preparatory committee (PrepCom III) for the September 1994 International Conference on Population and Development will be held in New York during April 4-22. Nongovernmental organization (NGO) representatives will take the opportunity to lobby and brief government delegates on draft documents at this final such meeting before the conference convenes in September. Preparations thus far point to an increasing international recognition of individual needs. The International Planned Parenthood Federation (IPPF) hopes PrepCom III will ensure that this recognition is reflected in the final recommendations to the conference and that government delegates work with NGOs to provide an appropriate framework for Cairo. A variety of IPPF and FPA staff will take part in the government and NGO forums, with IPPF Secretary General Halfdan Mahler addressing the opening session. On April 5, Dr. Mahler will release the new IPPF report on adolescent sexuality, Understanding Adolescents, highlighting the negative consequences of ignoring the sexual and reproductive health needs of young people. Programs need to treat young people with respect and dignity. The report profiles some programs which have been successful in locales around the world. IPPF hopes to convince decision makers that their political and financial commitment is needed to secure the health and well-being of today's and tomorrow's young people. Another report on the unmet need for family planning services among marginalized populations in Uganda, El Salvador, Ghana, Palestine, and the Philippines will be presented at a reception hosted by Dr. Sai and Dr. Mahler.

    Objective To develop and validate a survey instrument designed to measure team dynamics in primary care. Data Sources/Study Setting We studied 1,080 physician and nonphysician health care professionals working at 18 primary care practices participating in a learning collaborative aimed at improving team-based care. Study Design We developed a conceptual model and administered a cross-sectional survey addressing team dynamics, and we assessed reliability and discriminant validity of survey factors and the overall survey's goodness-of-fit using structural equation modeling. Data Collection We administered the survey between September 2012 and March 2013. Principal Findings Overall response rate was 68 percent (732 respondents). Results support a seven-factor model of team dynamics, suggesting that conditions for team effectiveness, shared understanding, and three supportive processes are associated with acting and feeling like a team and, in turn, perceived team effectiveness. This model demonstrated adequate fit (goodness-of-fit index: 0.91), scale reliability (Cronbach's alphas: 0.71–0.91), and discriminant validity (average factor correlations: 0.49). Conclusions It is possible to measure primary care team dynamics reliably using a 29-item survey. This survey may be used in ambulatory settings to study teamwork and explore the effect of efforts to improve team-based care. Future studies should demonstrate the importance of team dynamics for markers of team effectiveness (e.g., work satisfaction, care quality, clinical outcomes). PMID:25423886

    Introduction Identifying appropriate pre-exposure prophylaxis (PrEP) candidates is a challenge in planning for the safe and effective roll-out of this strategy. We explored the use of a validated HIV risk screening tool, HIV Incidence Risk Index for Men who have Sex with Men (HIRI-MSM), to identify “optimal” candidates among MSM testing at a busy sexual health clinic's community testing sites in Toronto, Canada. Methods Between November 2014 and April 2015, we surveyed MSM undergoing anonymous HIV testing at community testing sites in Toronto, Canada, to quantify “optimal” candidates for scaling up PrEP roll-out, defined as being at high objective HIV risk (scoring ≥10 on the HIRI-MSM), perceiving oneself at moderate-to-high HIV risk and being willing to use PrEP. Cascades were constructed to identify barriers to broader PrEP uptake. The association between HIRI-MSM score and both willingness to use PrEP and perceived HIV risk were explored in separate multivariable logistic regression analyses. Results Of 420 respondents, 64.4% were objectively at high risk, 52.5% were willing to use PrEP and 27.2% perceived themselves at moderate-to-high HIV risk. Only 16.4% were “optimal” candidates. Higher HIRI-MSM scores were positively associated with both willingness to use PrEP (aOR=1.7 per 10 score increase, 95%CI=1.3–2.2) and moderate-to-high perceived HIV risk (aOR=1.7 per 10 score increase, 95%CI=1.2–2.3). The proportion of men who were “optimal” candidates increased to 42.9% when the objective HIV risk cut-off was changed to top quartile of HIRI-MSM scores (≥26). In our full cascade, a very low proportion (5.3%) of MSM surveyed could potentially benefit from PrEP under current conditions. The greatest barrier in the cascade was low perception of HIV risk among high-risk men, but considerable numbers were also lost in downstream cascade steps. Of men at high objective HIV risk, 68.3% did not perceive themselves to be at moderate-to-high HIV risk

    2016-01-01

    Background In low and middle income countries (LMICs), and other areas with low resources and unreliable access to the Internet, understanding the emerging best practices for the implementation of new mobile health (mHealth) technologies is needed for efficient and secure data management and for informing public health researchers. Innovations in mHealth technology can improve on previous methods, and dissemination of project development details and lessons learned during implementation are needed to provide lessons learned to stakeholders in both the United States and LMIC settings. Objective The aims of this paper are to share implementation strategies and lessons learned from the development and implementation stages of two survey research projects using offline mobile technology, and to inform and prepare public health researchers and practitioners to implement new mobile technologies in survey research projects in LMICs. Methods In 2015, two survey research projects were developed and piloted in Puerto Rico and pre-tested in Costa Rica to collect face-to-face data, get formative evaluation feedback, and to test the feasibility of an offline mobile data collection process. Fieldwork in each setting involved survey development, back translation with cultural tailoring, ethical review and approvals, data collector training, and piloting survey implementation on mobile tablets. Results Critical processes and workflows for survey research projects in low resource settings were identified and implemented. This included developing a secure mobile data platform tailored to each survey, establishing user accessibility, and training and eliciting feedback from data collectors and on-site LMIC project partners. Conclusions Formative and process evaluation strategies are necessary and useful for the development and implementation of survey research projects using emerging mHealth technologies in LMICs and other low resource settings. Lessons learned include: (1) plan

    2014-01-01

    Prolyl endopeptidase (PREP) has been implicated in neuronal functions. Here we report that hypothalamic PREP is predominantly expressed in the ventromedial nucleus (VMH), where it regulates glucose-induced neuronal activation. PREP knockdown mice (Prepgt/gt) exhibited glucose intolerance, decreased fasting insulin, increased fasting glucagon levels, and reduced glucose-induced insulin secretion compared with wild-type controls. Consistent with this, central infusion of a specific PREP inhibitor, S17092, impaired glucose tolerance and decreased insulin levels in wild-type mice. Arguing further for a central mode of action of PREP, isolated pancreatic islets showed no difference in glucose-induced insulin release between Prepgt/gt and wild-type mice. Furthermore, hyperinsulinemic euglycemic clamp studies showed no difference between Prepgt/gt and wild-type control mice. Central PREP regulation of insulin and glucagon secretion appears to be mediated by the autonomic nervous system because Prepgt/gt mice have elevated sympathetic outflow and norepinephrine levels in the pancreas, and propranolol treatment reversed glucose intolerance in these mice. Finally, re-expression of PREP by bilateral VMH injection of adeno-associated virus–PREP reversed the glucose-intolerant phenotype of the Prepgt/gt mice. Taken together, our results unmask a previously unknown player in central regulation of glucose metabolism and pancreatic function. PMID:25071172

  18. Mechanism of Action of Prolyl Oligopeptidase (PREP) in Degenerative Brain Diseases: Has Peptidase Activity Only a Modulatory Role on the Interactions of PREP with Proteins?

    PubMed Central

    Männistö, Pekka T.; García-Horsman, J. Arturo

    2017-01-01

    In the aging brain, the correct balance of neural transmission and its regulation is of particular significance, and neuropeptides have a significant role. Prolyl oligopeptidase (PREP) is a protein highly expressed in brain, and evidence indicates that it is related to aging and in neurodegenration. Although PREP is regarded as a peptidase, the physiological substrates in the brain have not been defined, and after intense research, the molecular mechanisms where this protein is involved have not been defined. We propose that PREP functions as a regulator of other proteins though peptide gated direct interaction. We speculate that, at least in some processes where PREP has shown to be relevant, the peptidase activity is only a consequence of the interactions, and not the main physiological activity.

    1958-01-01

    Photogrammetry, the science or art of obtaining reliable measurements by means of photography, is now used extensively in topographic mapping. Precise photogrammetric plotting instruments now enable the map maker to extract from aerial photographs much.of the detailed information required for drawing the map that formerly was acquired by laborious ground surveys. Photography and photogrammetry have thus become essential components of all large mapping operations. The Geological Survey has played a leading role in the development of photogrammetric methods of mapping over a period of half a century. This role has been well documented in numerous articles appearing in technical publications during this time. It is the purpose of this circular to present, in brief form, the highlights of Geological Survey activities and developments in the field of photogrammetry, from pioneer efforts to present-day practice.

    Application of airborne geophysical surveys ranges in scale from detailed site scale such as locating abandoned well casing and saline water plumes to landscape scale for mapping hydrogeologic frameworks pertinent to ground water and tectonic settings relevant to studies of induced seismicity. These topics are important in understanding possible effects of hydrocarbon development on the environment. In addition airborne geophysical surveys can be used in establishing baseline "snapshots", to provide information in beneficial uses of produced waters, and in mapping ground water resources for use in well development. The U.S. Geological Survey (USGS) has conducted airborne geophysical surveys over more than 20 years for applications in energy resource environmental studies. A majority of these surveys are airborne electromagnetic (AEM) surveys to map subsurface electrical conductivity related to plumes of saline waters and more recently to map hydrogeologic frameworks for ground water and plume migration. AEM surveys have been used in the Powder River Basin of Wyoming to characterize the near surface geologic framework for siting produced water disposal ponds and for beneficial utilization in subsurface drip irrigation. A recent AEM survey at the Fort Peck Reservation, Montana, was used to map both shallow plumes from brine pits and surface infrastructure sources and a deeper concealed saline water plume from a failed injection well. Other reported applications have been to map areas geologically favorable for shallow gas that could influence drilling location and design. Airborne magnetic methods have been used to image the location of undocumented abandoned well casings which can serve as conduits to the near surface for coproduced waters. They have also been used in conjunction with geologic framework studies to understand the possible relationships between tectonic features and induced earthquakes in the Raton Basin.

  11. Lecture to inquiry: The transformation of a tech prep biology teacher

    NASA Astrophysics Data System (ADS)

    Haskell, Deborah Harris

    As teachers implement the National Science Education Standards (NRC, 1996) many have to reform the instructional methods they have used throughout their careers. This case study examines the transformation of Laurie, a 20-year teacher, during her first year of change from a "traditional" textbook/lecture style of teaching to a facilitator of an inquiry-based classroom. Implementing change requires not only pedagogical expertise, but also the belief that the modifications can be made and that the outcomes are significant. Using Bandura's social cognitive theory as a framework, changes in Laurie's self-efficacy, outcome expectancy, and motivation are followed throughout the transition. During her first year of change, Laurie used worksheets, small group activities, and guided inquiry activities, all strategies in which she had high self-efficacy and experienced positive student outcomes. She rarely used class forums, authentic assessment, and formative assessment. Factors that influenced her change were experiential professional development opportunities that allowed her to practice inquiry-based techniques, a change in her teaching environment from college prep chemistry to tech prep biology, autonomy regarding classroom decisions, and reflective decision making as she learned through experience. Using a standards-based biology textbook increased her self-efficacy toward using inquiry-based practices. The textbook format of embedding text in activities rather than adding activities to the text resulted in an increase of the number and frequency of activities done. Facilitating the textbook's Guided Inquiries and Extended Inquiries helped Laurie gain experience with inquiry-based methods. She also realized that when building from the students' concrete experiences, her students were able to attain higher-level thinking skills. The study revealed six factors contributing to Laurie's change process: (a) experiential professional development, (b) motivation for change

    The Information Flow Diagram for Literature Survey (IFDLS) has been developed to manage information and procedure in the literature survey phase of the PTAs selection process. It is a tool utilizing information technology, which can organize, analyze, and evaluate information from literature survey and manage their process systematically. IFDLS is able to show the flow of information and data, and the history of information management processing. Information coverage and quality is not homogenous throughout the country and, in some areas, there may not even be sufficient data available to be able to reach a judgment on conformity with the site-specific evaluation factors (SSEF). Literature surveys could only be conducted on a volunteer area before it is nominated as a PIA. However, the absence of information on any factor mentioned will not constitute disqualification of the area. On the contrary, an attempt to compare these sites with analogous areas in Japan will be done to assemble sufficient data and consequently make a decision on whether to proceed further. The application of IFDLS to literature survey phase of the PIA selection process is being proposed. The concept, construction, application and evolution of IFDLS towards application phase on a trial basis are discussed. (authors)

    Innovative curricula aim to improve content knowledge and the goal of helping students develop practices and skills of authentic scientist through active engagement learning. To students, these classroom practices often seem very different from their previous learning experiences in terms of behavioral expectations, learning attitude, and what learning means. We propose that productive participation in these learning environments require students to modify their identity as learners in addition to refining their science conceptual understanding. In order to measure changes in learning identity, we developed a 49-item survey to assess students' 1) expectations of student and teacher roles, 2) self efficacy towards skills supported in the Investigative Science Learning Environment (ISLE) and 3) attitudes towards social learning. Using principle components exploratory factor analysis, we have established two reliable factors with subscales that measure these student characteristics. This paper presents the survey development, validation and pilot study results.

    Pre-exposure prophylaxis (PrEP) is a biomedical intervention that can reduce rates of HIV transmission when taken once daily by HIV-negative individuals. Little is understood about PrEP uptake and retention in care among the populations most heavily impacted by the HIV epidemic, particularly among young men who have sex with men (YMSM) in the Deep South. Therefore, this study explored the structural, social, behavioral, and clinical factors that affect PrEP use and retention in care among YMSM in Jackson, Mississippi. Thirty MSM who were prescribed PrEP at an outpatient primary care clinic were interviewed and included 23 men who had been retained in PrEP care and seven who had not been retained. The mean age of participants was 26.6 years. Most (23) participants were African American. Major factors affecting PrEP use and retention in PrEP care included 1) structural factors such as cost and access to financial assistance for medications and clinical services; 2) social factors such as stigma and relationship status; 3) behavioral factors including sexual risk behaviors; and 4) clinical factors such as perceived and actual side effects. Many participants also discussed the positive spillover effects of PrEP use and reported that PrEP had a positive impact on their health. Four of the seven individuals who had not been retained re-enrolled in PrEP care after completing their interviews, suggesting that case management and ongoing outreach can enhance retention in PrEP care. Interventions to enhance retention in PrEP care among MSM in the Deep South will be most effective if they address the complex structural, social, clinical, and behavioral factors that influence PrEP uptake and retention in PrEP care.

    OligoPrep is a macroporous polyvinylacetate (PVA) biodegradable support that has been designed for cost-effective automated synthesis of oligonucleotides using standard phosphoramidite chemistry. Originally developed for large-scale oligonucleotide synthesis in beds and reactors, we present here its utility for medium-scale work of 1-10 micromol in column syntheses on standard DNA synthesizers. We show how an increase in scale, and, therefore, yield, can be achieved without significant increase in reagent quantity. Additional deblock and oxidation cycles can provide high coupling yields, and the use of concentrated ammonia in aqueous methylamine (AMA) for oligonucleotide cleavage and deprotection results in excellent recovery.

    Researchers determined a need to develop an instrument to assess the vending machine environment that was comparably reliable and valid to other Nutrition Environment Measures Survey tools and that would provide consistent and comparable data for businesses, schools, and communities. Tool development, reliability testing, and dissemination of the Nutrition Environment Measures Survey-Vending (NEMS-V) involved a collaboration of students, professionals, and community leaders. Interrater reliability testing showed high levels of agreement among trained raters on the products and evaluations of products. NEMS-V can benefit public health partners implementing policy and environmental change initiatives as a part of their community wellness activities. The vending machine project will support a policy calling for state facilities to provide a minimum of 30% of foods and beverages in vending machines as healthy options, based on NEMS-V criteria, which will be used as a model for other businesses.

    Although research has demonstrated that marriage education has positive effects on relationship quality, little is known about how such services impact relationships where one partner is incarcerated. The current study implemented an adapted version of the Prevention and Relationship Enhancement Program (PREP Inside and Out) for inmates in Oklahoma correctional facilities. Inmates, with or without their partners, participated in the 12-hour program. The impact of the program was investigated on a range of relationship variables including satisfaction with relationship, dedication, confidence, communication skills, friendship, and negative interactions as reported by the inmate partner. Participants reported substantial gains in all variables and in overall satisfaction with their relationship after completing the program, regardless of their gender and racial/ethnic background. Implications for future marriage education programs and research in prisons are discussed.

    The Scientific Knowledge for Indian Learning and Leadership (SKILL) precollege college program of the South Dakota School of Mines and Technology concluded the 1994 PREP program on July 22, 1994. The program graduated 22 students from the 4-week residential math/science program for American Indian students. Primary academic focus was physics (30 hours); each student was given a bicycle to solve problems on angular momentum and mechanical advantage. Mathematical calculations and problem solving exercises were done in mathematics class (20 hours). Preliminary results in math, physics, and geology show dramatic increases in student achievement over the 4- week period. The program paired every two students with a faculty member or research scientist, and each team completed a research project.

    OBJECTIVE To understand the career development needs of an international multidisciplinary group of critical care practitioners in the 21st century. DESIGN A web-accessible survey deployed by the In-Training Section of the Society of Critical Care Medicine (SCCM). SETTING University health sciences center. SUBJECTS Physicians (MD, DO), Advanced Practice Provider (NP, PA), Nurses (RN), Pharmacists, and Student members of the SCCM. INTERVENTIONS The survey covered domains of demographics, opinions about career development, and opinions about the SCCM In-Training Section. MEASUREMENTS AND MAIN RESULTS 1,049 of approximately 16,000 SCCM members responded to the survey (7% response rate). Continuing education (280, 26.7%), leadership skills (197, 18.8%), and scientific development (192, 18.3%) are among the most important issues for the respondents. Many critical care practitioners would like to assist SCCM's efforts in career development (948, 90.4%) and many would consider some aspect of committee involvement (796, 75.9%). The SCCM In-Training Section, whose primary mission is career development across the spectrum of providers and expertise levels, needs improved advertisement (981, 93.7%). There is strong support for upcoming Annual Congresses dedicated to career development (834, 79.5%). Of the three main methods of information dissemination for SCCM career development initiatives from the In-Training Section, respondents rank email highest (762, 72.6%), followed by webpages (228, 21.7%) and I-rooms (59, 5.6%). Over half of the SCCM membership surveyed lack a career development mentor in critical care. CONCLUSIONS This is the largest assessment of the international critical care community regarding the career development needs of 21st century critical care practitioner, although the limited response rate makes this work prone to sampling bias. Career development issues are broad and in need of further development by the SCCM In-Training Section. Although these

    Human PREP1 and PBX1 are homeodomain transcriptional factors, whose biochemical and structural characterization has not yet been fully described. Expression of full-length recombinant PREP1 (47.6 kDa) and PBX1 (46.6 kDa) in E. coli is difficult because of poor yield, high instability and insufficient purity, in particular for structural studies. We cloned the cDNA of both proteins into a dicistronic vector containing an N-terminal glutathione S-transferase (GST) tag and co-expressed and co-purified a stable PBX1:PREP1 complex. For structural studies, we produced two C-terminally truncated complexes that retain their ability to bind DNA and are more stable than the full-length proteins through various purification steps. Here we report the production of large amounts of soluble and pure recombinant human PBX1:PREP1 complex in an active form capable of binding DNA. PMID:25856340

    The pre-exposure prophylaxis (PrEP) drug Truvada is a new HIV prevention technology that is predominantly promoted as relevant to HIV-negative gay men. This paper explores what PrEP represents for HIV-positive gay men living in Paris, based upon data collected through interviews and ethnographic research. While HIV-positive gay men do not directly consume Truvada through PrEP, they nonetheless hold opinions and understandings of this drug, specifically as it relates to their own sexuality. This paper expands the representations and meanings of this new technology in a different light through the voices of gay men living with HIV in Paris. The main argument of this article is that PrEP as an additional HIV prevention tool blurs the lines between science, technologies and human sexuality.

    A new affinity column packing for removal of endotoxins has been prepared by coupling USP drug-quality polymyxin B to Affi-Prep, a novel synthetic macroporous polymer. Affi-Prep Polymyxin binds endotoxins from a number of different strains of gram-negative bacteria. Endotoxin binding is not significantly affected by 10 mg/ml of bovine serum albumin or human immunoglobulin G, by 1 mg/ml sodium dodecyl sulphate, or by 1 mg/ml deoxycholate. Affi-Prep Polymyxin is stable to treatment with 1.0 M sodium hydroxide, an important property for sanitizing the resin. The resin shows a high ligand stability, since no leakage of polymyxin B from the packing could be detected. Affi-Prep Polymyxin exhibited the highest endotoxin binding efficiency when compared with several commercial agarose affinity packings.

    The tobacco industry recently introduced a new set of "safe" cigarettes and nicotine delivery devices that purportedly entail reduced tobacco-related disease risk due to their lower level of some carcinogens and toxins. Little is know about the biological impact of these potential reduced exposure products (PREPs) and nothing is known about their advertising and availability. Hence, two pilot studies were conducted to examine the latter issues for the first time. In Study 1, we examined tobacco ads in 10 popular magazines 1998--2002 and found that only 1% of ads were for PREPs. In Study 2, we attempted to purchase PREPs in a random sample of 113 small stores and found that only 4.4% sold any PREP. These preliminary findings tentatively suggest that the industry might not yet be heavily invested in products that have the potential to increase tobacco use by decreasing its perceived harm. Studies with larger samples are recommended.

    We have examined glucose homeostasis in mice hypomorphic for the homeotic transcription factor gene Prep1. Prep1-hypomorphic (Prep1(i/i)) mice exhibit an absolute reduction in circulating insulin levels but normal glucose tolerance. In addition, these mice exhibit protection from streptozotocin-induced diabetes and enhanced insulin sensitivity with improved glucose uptake and insulin-dependent glucose disposal by skeletal muscle. This muscle phenotype does not depend on reduced expression of the known Prep1 transcription partner, Pbx1. Instead, in Prep1(i/i) muscle, we find normal Pbx1 but reduced levels of the recently identified novel Prep1 interactor p160. Consistent with this reduction, we find a muscle-selective increase in mRNA and protein levels of PGC-1alpha, accompanied by enhanced expression of the GLUT4 transporter, responsible for insulin-stimulated glucose uptake in muscle. Indeed, using L6 skeletal muscle cells, we induced the opposite effects by overexpressing Prep1 or p160, but not Pbx1. In vivo skeletal muscle delivery of p160 cDNA in Prep1(i/i) mice also reverses the molecular phenotype. Finally, we show that Prep1 controls the stability of the p160 protein. We conclude that Prep1 controls insulin sensitivity through the p160-GLUT4 pathway.

    2014-01-01

    Pre-exposure prophylaxis (PrEP) with antiretroviral drugs is a novel biomedical intervention that can prevent HIV transmission among high-risk populations. As findings from multiple PrEP studies have suggested that adherence is vital to achieve the full prevention benefits of PrEP, it is important to understand the clinical pharmacology and pharmacokinetic (PK) properties of PrEP antiretrovirals, the association of PK and PrEP efficacy and the potential for drug concentration measurement to be used as a tool to monitor PrEP adherence. In this review, we examine studies related to PrEP adherence with attention to the clinical pharmacology and pharmacokinetics of current and novel PrEP agents. Studies of animal models, pharmacokinetics and clinical trials related to PrEP and adherence were reviewed. In summary, when combined as part of a comprehensive prevention strategy that includes use of condoms and risk reduction counseling, PrEP has tremendous promise as a adjunctive biomedical HIV prevention intervention, providing that adherence is maintained.

    Planaria continue to blossom as a model system for understanding all aspects of regeneration. They provide an opportunity to understand how the replacement of missing tissues from preexisting adult tissue is orchestrated at the molecular level. When amputated along any plane, planaria are capable of regenerating all missing tissue and rescaling all structures to the new size of the animal. Recently, rapid progress has been made in understanding the developmental pathways that control planarian regeneration. In particular Wnt/beta-catenin signaling is central in promoting posterior fates and inhibiting anterior identity. Currently the mechanisms that actively promote anterior identity remain unknown. Here, Smed-prep, encoding a TALE class homeodomain, is described as the first gene necessary for correct anterior fate and patterning during planarian regeneration. Smed-prep is expressed at high levels in the anterior portion of whole animals, and Smed-prep(RNAi) leads to loss of the whole brain during anterior regeneration, but not during lateral regeneration or homeostasis in intact worms. Expression of markers of different anterior fated cells are greatly reduced or lost in Smed-prep(RNAi) animals. We find that the ectopic anterior structures induced by abrogation of Wnt signaling also require Smed-prep to form. We use double knockdown experiments with the S. mediterranea ortholog of nou-darake (that when knocked down induces ectopic brain formation) to show that Smed-prep defines an anterior fated compartment within which stem cells are permitted to assume brain fate, but is not required directly for this differentiation process. Smed-prep is the first gene clearly implicated as being necessary for promoting anterior fate and the first homeobox gene implicated in establishing positional identity during regeneration. Together our results suggest that Smed-prep is required in stem cell progeny as they form the anterior regenerative blastema and is required for

    In March 2012, the SAGE Working Group on Vaccine Hesitancy was convened to define the term "vaccine hesitancy", as well as to map the determinants of vaccine hesitancy and develop tools to measure and address the nature and scale of hesitancy in settings where it is becoming more evident. The definition of vaccine hesitancy and a matrix of determinants guided the development of a survey tool to assess the nature and scale of hesitancy issues. Additionally, vaccine hesitancy questions were piloted in the annual WHO-UNICEF joint reporting form, completed by National Immunization Managers globally. The objective of characterizing the nature and scale of vaccine hesitancy issues is to better inform the development of appropriate strategies and policies to address the concerns expressed, and to sustain confidence in vaccination. The Working Group developed a matrix of the determinants of vaccine hesitancy informed by a systematic review of peer reviewed and grey literature, and by the expertise of the working group. The matrix mapped the key factors influencing the decision to accept, delay or reject some or all vaccines under three categories: contextual, individual and group, and vaccine-specific. These categories framed the menu of survey questions presented in this paper to help diagnose and address vaccine hesitancy.

Approximately, 9.7% of participants had ever used PrEP; 87% of those deemed good candidates for screening (indicated by a Centers for Disease Control and Prevention risk index score ≥10) were not current or past users. PrEP use was associated with higher income [adjusted odds ratio (aOR): 4.13; confidence interval (CI): 1.87 to 9.12], receptive condomless anal sex (aOR: 3.41; CI: 1.71 to 6.78), HIV-positive sex partners (aOR: 2.87; CI: 1.53 to 5.38), popper use (aOR: 3.47; CI: 1.96 to 6.13), and recent sexually transmitted infection diagnosis (aOR: 2.90; CI: 1.64 to 5.13). Some users (41.5%) wanted help remembering to take PrEP. The top reason for discontinuation was concern about long-term side effects (33.0%). Young men who have sex with men app users are prime candidates for PrEP, despite low uptake. Apps may be useful tools for PrEP information dissemination, adherence monitoring, and support.

    Community outreach efforts to increase HIV pre-exposure prophylaxis (PrEP) utilization by at risk men-who-have-sex-with-men (MSM) first need to elucidate preferences for learning about PrEP and linking to PrEP resources. In this pilot study, we observed that among MSM recruited through community outreach, HIV sexual risk-taking was significant, yet self-perceived PrEP knowledge was low and interest in learning more about PrEP was moderate. Most preferred learning about PrEP and being provided local PrEP clinic information through electronic media. However, receipt of PrEP information alone did not appear to motivate these men into presenting to a local clinic for PrEP evaluation. PMID:27076865

  12. Barriers and facilitators to pre-exposure prophylaxis (PrEP) eligibility screening and ongoing HIV testing among target populations in Bondo and Rarieda, Kenya: Results of a consultation with community stakeholders

    2014-01-01

    Background As pre-exposure prophylaxis (PrEP) moves closer to availability in developing countries, practical considerations for implementation become important. We conducted a consultation with district-level community stakeholders experienced in HIV-prevention interventions with at-risk populations in Bondo and Rarieda, Kenya to generate locally grounded approaches to the future rollout of oral PrEP to four populations: fishermen, widows, female sex workers, and serodiscordant couples. Methods The 20 consultation participants represented the Ministry of Health, faith- and community-based organizations, health facilities, community groups, and nongovernmental organizations. Participants divided into breakout groups and followed a structured discussion guide asking them to identify barriers to implementing HIV-prevention interventions (including PrEP) with each population. Questions also solicited solutions for addressing these barriers, as well as other facilitators for PrEP implementation. In particular, questions focused on how to encourage people to screen for PrEP eligibility by having HIV and other blood tests and how to encourage compliance with ongoing HIV testing. Results The barriers and facilitators/solutions discussants provided were frequently population-specific, but there were also broad-level similarities across populations. Service delivery barriers to HIV-prevention interventions concerned the need for staff trained to address the needs of particular populations. Service delivery facilitators to provision of ongoing HIV testing consisted of offering testing options besides facility-based testing. Stigma was the main community-level barrier for all groups, whereas barriers at the level of target populations included mobility; lifestyle and life circumstances, especially cultural norms among fishermen and widows; and fears, lack of awareness, and misinformation. Proposed facilitators and strategies for addressing community- and population

  14. Development of an Introductory Oceanography Concept Inventory Survey

    Arthurs, L.; Marchitto, T.

    2008-12-01

    Concept inventories are one type of assessment that can be used to evaluate whether a student has an accurate and working knowledge of a specific set of concepts. Although such assessment tools have been developed in astronomy, biology, chemistry, engineering, fluid mechanics, geology, and physics, none has been available. Our development of an Introductory Oceanography Concept Inventory Survey (IO-CIS) serves to fill this gap. Much of the development of the IO-CIS utilized students enrolled in the Spring 2008 Introduction to Oceanography course taught at the University of Colorado at Boulder. The first step in the development of IO-CIS involved the identification and selection of the critical concepts to be addressed in the course and the survey. Next, learning goals were defined for each critical concept. These learning goals then provided the basis for framing open-ended questions that were administered to students in pre-module in-class Concept Inventory Exercises (CIEs). These open-ended questions each underwent validation and revision with expert and novice input prior to being administered in a CIE. Each CIE comprised 4-5 open-ended questions, which each contained 1-4 parts. During the semester, 4 different CIEs were administered, with the number of respondents for each CIE ranging from 57-134. Student responses were then binned according to misconceptions and alternate conceptions, tallied, and "distractors" were written based on the most popular bins using the same language employed by students in their responses. Student responses were also used as part of the validation process to ensure that the questions were interpreted by students in the manner intended. Student responses were also used as a basis to discard particular questions from inclusion in the overall IO-CIS. After the initial IO-CIS questions and distractors had been designed as described above, 23 one-on-one student interviews were conducted as part of the validation process. As a result of

    2016-08-29

    Background: In Australia, the preventative use of antiretroviral drugs [pre-exposure prophylaxis (PrEP) and treatment as prevention] is being embraced to protect individuals at high risk of HIV and reduce onward transmission. Methods: The adaptation of a behavioural surveillance system, the Gay Community Periodic Surveys, was reviewed to monitor the uptake and effect of new prevention strategies in Australia's primary HIV-affected population (gay and bisexual men, GBM). The national trends in key indicators during 2000-15 were reviewed and a new measure to take account of antiretroviral-based prevention was developed. Results: Between 2000 and 2015, there were significant increases (P<0.001) in annual HIV testing (56.1-64.8%), condomless sex with casual partners (26.8-38.8%) and the proportion of HIV-positive men on HIV treatment (72.5-88.4%) and with an undetectable viral load (73.7-94.7%). The proportion of casual partners who were HIV negative, not on PrEP and who engaged in receptive condomless sex also increased between 2000 and 2015 from 12.8 to 19.3%. Two scenarios anticipating the effect of PrEP highlighted the need to target GBM who engage in receptive condomless sex while also sustaining condom use at a population level. Conclusions: Behavioural surveillance can be successfully adapted to follow the effect of antiretroviral-based prevention. It is anticipated that HIV testing and HIV treatment will continue to increase among Australian GBM, but to prevent new infections, intervention in the growing proportion of GBM who have condomless sex with casual partners is needed. For PrEP to have its desired effect, condom use needs to be sustained.

    The National Survey of Compensation Paid Scientists and Engineers Engaged in Research and Development (NSC) has been conducted for the Department of Energy since 1967. During this time the NSC has come to be considered the most comprehensive survey of its kind available in the United States. Its methodology and results are reliable and highly useful to compensation personnel in research and development (R and D) establishments. Each year project staff pinpoint areas of improvement which are necessary and desirable. The three tasks that are the subject of this report have been undertaken to maintain and improve the NSC and increase its usefulness to participants. The three tasks are: an update of the universe listing; comparison of NSC survey methodology and results with other surveys of research and development professionals; and development of a methodology to project salaries for the near-term. Each task is described.

    Psychological measurement in regard to using drugs, alcohol, or other substances should attend to personological, attitudinal, and informational factors. Standardized tests are available for assessing personological and attitudinal variables, but not for knowledge. To develop a test of information, 45 multiple-choice items were correlated with total and part scores in samples of 132 men and 71 women; 35 items with significant (p less than .05) coefficients and other desirable properties were retained for a Drug and Alcohol Information Survey (DAIS). For 33 male and 36 female college students participating in an intensive psychological assessment program, scores on the DAIS were positively associated with (1) ratings of modernity, sensation seeking, originality, and nonorderliness; (2) personality scales for status propensity, sociability, social presence, and rebelliousness; and (3) a nonverbal test of field-independent cognitive ability. High scorers on the DAIS also reported more frequent use of marijuana, alcohol, and tobacco than did students with low scores.

    To help address the relationship needs of service members, there have been a number of programs offered within active duty and veteran contexts. One program, offered within the Strong Bonds portfolio delivered by Army Chaplains, is PREP for Strong Bonds (PREP = the Prevention and Relationship Education Program). PREP has a number of empirically based and tested variants. This article reviews the disseminated research regarding results from a large randomized clinical trial designed to test the effectiveness of PREP for Strong Bonds. From a sample of 662 Army couples drawn from two sites, outcome papers have focused on different subsamples, marital outcomes, follow up time points, and moderators. Reviewing these disseminated outcomes, we conclude that PREP for Strong Bonds has significant divorce reduction effects at one site; these divorce effects were found at both one and two years post intervention, and were moderated by factors such as minority status, economic strain, and cohabitation history of the couple. In terms of marital quality outcomes, some modest overall effects were found pre to post intervention, but there were no overall marital quality outcome effects two years post intervention. However, marital quality outcomes are significantly moderated by infidelity and cohabitation history, with couples reporting these risk factors showing greater positive marital quality outcomes. These results to date are discussed in terms of clinical and research implications as well as directions for future work, such as examining longer term preventative effects. PMID:26366041

    PubMed

    Caci, Jennifer B

    2015-01-01

    Medical intelligence is an underused or sometimes misapplied tool in the protection of our Soldiers and the execution of nonkinetic operations. The somewhat improved infrastructure of the operational environment in Iraq and Afghanistan led to an inevitable sense of complacency in regard to the threat of disease nonbattle injury (DNBI). The picture changed somewhat in 2010 with the advent of the village stability program and the establishment of SOF camps in austere locations with degraded living situations rife with exposure risks. In addition, the increasing deployments to unstable locations around the globe, reminiscent of typical Special Operations Forces (SOF) missions before the Global War on Terrorism, indicate a need for better preparation for deployment from the standpoint of disease risk and force health protection. A knowledge gap has developed because we simply did not need to apply as stringent an evaluation of DNBI risk in environments where improved life support mitigated the risk for us. The tools necessary to decrease or even eliminate the impact of DNBI exist but they must be shared and implemented. This article will present four vignettes from current and former SOF Force Health Protection personnel starting with a simple method of executing Medical Intelligence Prep of the Environment (MIPOE) and highlighting situations in which it either was or could have been implemented to mitigate risk and decrease the impact on mission accomplishment and individual operators. A follow-on article will present vignettes of the successful application of MIPOE to nonkinetic operations.

    Pre-exposure prophylaxis (PrEP) is effective for preventing HIV among HIV-serodiscordant heterosexual couples. Gender roles may influence perceived personal and social risks related to HIV-prevention behaviors and may affect use of PrEP. In this study, interviews and focus groups were conducted with 68 individuals from 34 mutually disclosed serodiscordant heterosexual partnerships in Thika, Kenya. Sociocultural factors that affect adherence to PrEP were explored using grounded analysis. Three factors were identified, which shape perceptions of PrEP: gendered power dynamics and control over decision-making in the household; conflicts between risk-reduction strategies and male sexual desire; culture-bound definitions of women's work. Adherence to PrEP in the Partners PrEP Study was high; however, participants articulated conflicting interests related to PrEP in connection with traditional gender roles. The successful delivery of PrEP will require understanding of key social factors, particularly related to gender and dyadic dynamics around HIV serostatus.

    2015-11-15

    Reductions in human immunodeficiency virus (HIV) incidence with pre-exposure prophylaxis (PrEP) for men who have sex with men (MSM) will require significant coverage of those at risk. We propose a simplified framework, similar to the HIV care continuum, to achieve protection with PrEP as follows: 1. At-risk MSM; 2. Awareness of and willingness to take PrEP; 3. Access to healthcare; 4. Receiving a prescription; and 5. Adhering to effective PrEP. We evaluated the PrEP care continuum on an Atlanta cohort of MSM and projected how many MSM might achieve protection from HIV. Even with optimistic estimates, few Atlanta MSM (15%) are projected to achieve protection from HIV with PrEP given the significant barriers described. Each continuum step represents an important point for intervention that could substantially increase the overall effectiveness of PrEP. In addition, novel strategies for PrEP delivery are needed to achieve the necessary effectiveness for Atlanta MSM at risk of HIV.

    Langer, Marie; Braithwaite, Graham R.

    2016-01-01

    Objective: Based on the line operations safety audit (LOSA), two studies were conducted to develop and deploy an equivalent tool for aircraft maintenance: the maintenance operations safety survey (MOSS). Background: Safety in aircraft maintenance is currently measured reactively, based on the number of audit findings, reportable events, incidents, or accidents. Proactive safety tools designed for monitoring routine operations, such as flight data monitoring and LOSA, have been developed predominantly for flight operations. Method: In Study 1, development of MOSS, 12 test peer-to-peer observations were collected to investigate the practicalities of this approach. In Study 2, deployment of MOSS, seven expert observers collected 56 peer-to-peer observations of line maintenance checks at four stations. Narrative data were coded and analyzed according to the threat and error management (TEM) framework. Results: In Study 1, a line check was identified as a suitable unit of observation. Communication and third-party data management were the key factors in gaining maintainer trust. Study 2 identified that on average, maintainers experienced 7.8 threats (operational complexities) and committed 2.5 errors per observation. The majority of threats and errors were inconsequential. Links between specific threats and errors leading to 36 undesired states were established. Conclusion: This research demonstrates that observations of routine maintenance operations are feasible. TEM-based results highlight successful management strategies that maintainers employ on a day-to-day basis. Application: MOSS is a novel approach for safety data collection and analysis. It helps practitioners understand the nature of maintenance errors, promote an informed culture, and support safety management systems in the maintenance domain. PMID:27411354

    Abstract Since the July 2012 approval by the FDA of emtricitabine/ tenofovir disoproxil fumarate (Truvada) for use as pre-exposure prophylaxis (PrEP) against HIV, its feasibility and acceptability has been under study. HIV-discordant couples are likely targets for PrEP but little is known about how this new prevention tool impacts relationships. We examined, among gay male couples, the acceptability of individual and partner use of PrEP and intentions to use condoms with primary and outside partners in the context of PrEP use. Data are from two independent samples of couples recruited in the San Francisco bay area and New York City—a qualitative one (N=48 couples) between March and November, 2011, and a quantitative one (N=171 couples) between June, 2012 and May, 2013. Data were categorized by couple HIV status and general linear models; chi-square tests of independence were used to examine condom-use intentions with primary and outside partners, by sexual risk profile, and race. Almost half of the HIV-negative couples felt PrEP was a good HIV prevention strategy for themselves and their partner. Over half reported that they would not change their current condom use if they or their partner were taking PrEP. However, approximately 30% of HIV-negative couples reported that they would stop using condoms or use them less with primary and outside partners if they were on PrEP or if their partner was on PrEP. A large percentage of couples view PrEP positively. However, to ensure safety for both partners, future programing must consider those who intend not to use condoms while on PrEP. PMID:26057304

    Sevelius, Jae M; Deutsch, Madeline B; Grant, Robert

    2016-01-01

    Introduction Globally, transgender (“trans”) women are one of the key populations most disproportionately impacted by HIV. Pre-exposure prophylaxis (PrEP) is the newest and most promising biomedical HIV prevention intervention to date. This paper reviews relevant literature to describe the current state of the science and describes the potential role of PrEP among trans women, including a discussion of unique considerations for maximizing the impact of PrEP for this vulnerable population. Methods Available information, including but not limited to existing scientific literature, about trans women and PrEP was reviewed and critiqued based on author expertise, including PrEP clinical trials and rollout. Results To date, PrEP demonstration projects and clinical trials have largely excluded trans women, or have not included them in a meaningful way. Data collection strategies that fail to identify trans women in clinical trials and research further limit the ability to draw conclusions about trans women's unique needs and devise strategies to meet them. Gender-affirming providers and clinic environments are essential components of any sexual health programme that aims to serve trans women, as they will largely avoid settings that may result in stigmatizing encounters and threats to their identities. While there is currently no evidence to suggest drug-drug interactions between PrEP and commonly used feminizing hormone regimens, community concerns about potential interactions may limit interest in and uptake of PrEP among trans women. Conclusions In scaling up PrEP for trans women, it is essential to engage trans communities, utilize trans-inclusive research and marketing strategies and identify and/or train healthcare providers to provide gender-affirming healthcare to trans women, including transition-related care such as hormone provision. PrEP implementation guidelines must consider and address trans women's unique barriers and facilitators to uptake and

    Advances in biomedical interventions to prevent HIV offer great promise in reducing the number of new infections across sub- Saharan Africa, particularly among vulnerable populations such as female sex workers. Several recent trials testing pre-exposure prophylaxis (PrEP) have demonstrated efficacy, although others have been stopped early for futility. Given the importance and complexities of social and behavioural factors that influence biomedical approaches to prevention, we discuss several key areas of consideration moving forward, including trial participation, adherence strategies, social relationships, and the structural factors that shape PrEP interest, use, and potential effectiveness among female sex workers in sub-Saharan Africa. Our review highlights the importance of involving social scientists in clinical and community-based research on PrEP. We advocate for a shift away from a singular "re-medicalization" of the HIV epidemic to that of a "reintegration" of interdisciplinary approaches to prevention that could benefit female sex workers and other key populations at risk of acquiring HIV.

    The PrepFiler Forensic DNA Extraction Kit enables isolation of genomic DNA from a variety of biological samples. The kit facilitates reversible binding of DNA with magnetic particles resulting in high DNA recovery from samples with very low and high quantities of biological materials: 0.1 and 40 microL of human blood (donor 2) provided 14 and 2883 ng of DNA, respectively. Following the revised SWGDAM guidelines, performance of the developed method was investigated using different sample types including saliva on swabs, semen stains on cotton fabric, samples exposed to environment, samples with polymerase chain reaction (PCR) inhibitors, blood stains (on denim, cotton cloth, and FTA paper), and touch evidence-type samples. DNA yields for all samples tested were equal or better than those obtained by both phenol-chloroform extraction and commercial kits tested. DNA obtained from these samples was free of detectable PCR inhibitors. Short tandem repeat profiles were complete, conclusive, and devoid of PCR artifacts.

    1995-01-01

    The increasing complexity of engineering systems has sparked increasing interest in multidisciplinary optimization (MDO). This paper presents a survey of recent publications in the field of aerospace where interest in MDO has been particularly intense. The two main challenges of MDO are computational expense and organizational complexity. Accordingly the survey is focussed on various ways different researchers use to deal with these challenges. The survey is organized by a breakdown of MDO into its conceptual components. Accordingly, the survey includes sections on Mathematical Modeling, Design-oriented Analysis, Approximation Concepts, Optimization Procedures, System Sensitivity, and Human Interface. With the authors' main expertise being in the structures area, the bulk of the references focus on the interaction of the structures discipline with other disciplines. In particular, two sections at the end focus on two such interactions that have recently been pursued with a particular vigor: Simultaneous Optimization of Structures and Aerodynamics, and Simultaneous Optimization of Structures Combined With Active Control.

    This report builds upon our previous study, which described five patterns of why college graduates join National Institutes of Health (NIH)-funded diversity-focused Postbaccalaureate Research Education Programs (PREP). A 2015 report from the NIH showed that a high fraction of PREP participants matriculate into PhD and MD/PhD programs. This current study reveals how participants change during PREP, the program elements that facilitate change, and how identity as a graduate student and future scientist develops. Data come from in-depth interviews done at the beginning and end of PREP with 48 individuals from seven PREP programs. Results reveal three domains of development: academics, research, and presentation of oneself; each domain contains a developmental continuum. Key attributes of PREP enabling development include opportunities to attend graduate-level classes and seminars; time to practice reading literature; extended lab time with one's own project; high and explicit expectations from mentors; and multiple opportunities to talk about science and improve communication skills. PREP enabled participants to develop their identities as graduate students and to anticipate being seen by others as highly prepared for PhD training. After PREP, 85% (n = 41) started the PhD or MD/PhD, making PREP an intervention approach with great potential to broaden participation in biomedical PhD programs.

    Aim To study the incidence of harassment in the workplace among teachers at primary and secondary schools. Methods We analyzed the existing questionnaires on harassment in the workplace and developed a new one was to specifically address harassment of teachers in the public education sector. The questionnaire was then experimentally applied to a sample of 764 primary and secondary school teachers in Split Dalmatia County, Croatia. It included three scales –exposure to harassment, witnessing harassment, and disturbance by harassment. Validity of the three scales was examined by factor analysis. Results All three scales showed satisfactory metric characteristics: Cronbach α coefficient was 0.93 for exposure scale, 0.95 for witnessing scale, and 0.97 for disturbance scale. Out of 764 teachers surveyed, 164 (22.4%) were exposed to and 192 (31.7%) witnessed different kinds of harassment in the previous 12 months. There were significantly more of those who experienced harassment as witnesses (χ21 = 249.301; P < 0.001) than as direct victims. Eighty-six teachers (11.5%) reported having psychological and 76 (10.1%) physical health problems caused by their work. Exclusion as a consequence of harassment disturbed women more than men (χ21 = 5.27; P = 0.022). Those who were exposed to harassment had significantly lower median age (42; range 23-68) than those who were not exposed (45; range 23-65) (U = 31401.50; z = 2.129; P = 0.033). Conclusion The questionnaire registered wide spectrum of harassment types, indicating the need for continuous monitoring and systematic work on the prevention of these phenomena. The study showed that exposure to harassment is associated with age, indicating that younger teachers should be the target population for detection and prevention of workplace harassment.

    Purpose An investment in PrEP delivery must have public health impact in reducing HIV infections. Sustainable delivery of PrEP requires policy, integration of services and synergy with other existing HIV prevention programs. This review discusses key policy and programmatic considerations for implementation and scale up of PrEP in Africa. Recent Findings PrEP delivery has been delayed by concerns about adherence and delivery in ‘real world’ settings. Demonstration projects and clinical service delivery models are providing evidence of PrEP effectiveness with an impact much higher than that found in randomized clinical trials. Data confirm that PrEP uptake, adherence and retention has been high, more so by persons who perceive themselves at high risk for HIV infection, and PrEP is well tolerated. PrEP delivery is more than dispensation of a pill and programs should address other risk drivers, which differ by population. In Africa, barriers to PrEP uptake and adherence include stigma among MSM and low HIV risk perception among young women. Additional data have provided insight into optimal points of service delivery, provider training requirements and quality assurance needs. Of the 2 million new HIV infections in 2014, 70% were in Africa. PrEP use is not lifelong and use limited to periods of risk may be both effective and cost-effective for the continent. Summary HIV prevention programs should determine strategies to identify those at substantial risk for HIV infection, formulate and deliver PrEP in combination with interventions that target social drivers of HIV vulnerability specific to each population. Policy guidance for optimal combination of interventions and service delivery avenues, clinical protocols, health infrastructure requirements are required. Cost-effectiveness and efficiency data are essential for policy guidance to navigate ethical questions over use of antiretroviral therapy for HIV negative individuals when treatment coverage has not been

  17. Commentary: the value of PrEP for people who inject drugs

    PubMed Central

    Coleman, Rosalind L; McLean, Susie

    2016-01-01

    Introduction The offer of pre-exposure prophylaxis (PrEP) is recommended as an additional option for HIV prevention for people at substantial risk of HIV infection as part of combination HIV prevention approaches. Implementing this depends on integrating PrEP in public health programmes that address risky practices with evidence-based interventions, and that operate in an enabling legal and policy environment for the delivery of health services to those at higher risk of HIV infection. What does this recommendation mean in terms of the diverse range of HIV prevention needs of key populations, some of whom are so discriminated against that they exist essentially outside formal systems such as national public health services, and for whom a substantial risk of HIV is part of a larger adverse and hostile situation? We discuss this question with reference to people who inject drugs, informed by concerns and comments that emerged from a series of consultations. Discussion HIV prevention is part of a spectrum of injecting drug users’ priorities, and their access and uptake of HIV prevention services is contingent on their wider “risk environment.” The need to address structural barriers to services and human rights violations, and to improve access to comprehensive harm reduction programmes are of prime importance and would have higher value than a mono-focus on HIV prevention. Where existing harm reduction activities are inadequate, fragile or dependent on external donors, shifts in funding priorities, including, for example, towards PrEP, could threaten investment in the broader programmes. For these reasons, it cannot be assumed that PrEP promotion will always be supported by people who inject drugs. The sexual partners of people who inject drugs, non-opioid users who also inject and for whom there is no established substitution treatment, as well as drug users who are unable to negotiate safe sex may value PrEP. As for all key populations, the involvement of

    2015-01-01

    Introduction Young key populations, defined in this article as men who have sex with men, transgender persons, people who sell sex and people who inject drugs, are at particularly high risk for HIV. Due to the often marginalized and sometimes criminalized status of young people who identify as members of key populations, there is a need for HIV prevention packages that account for the unique and challenging circumstances they face. Pre-exposure prophylaxis (PrEP) is likely to become an important element of combination prevention for many young key populations. Objective In this paper, we discuss important challenges to HIV prevention among young key populations, identify key components of a tailored combination prevention package for this population and examine the role of PrEP in these prevention packages. Methods We conducted a comprehensive review of the evidence to date on prevention strategies, challenges to prevention and combination prevention packages for young key populations. We focused specifically on the role of PrEP in these prevention packages and on young people under the age of 24, and 18 in particular. Results and discussion Combination prevention packages that include effective, acceptable and scalable behavioural, structural and biologic interventions are needed for all key populations to prevent new HIV infections. Interventions in these packages should meaningfully involve beneficiaries in the design and implementation of the intervention, and take into account the context in which the intervention is being delivered to thoughtfully address issues of stigma and discrimination. These interventions will likely be most effective if implemented in conjunction with strategies to facilitate an enabling environment, including increasing access to HIV testing and health services for PrEP and other prevention strategies, decriminalizing key populations’ practices, increasing access to prevention and care, reducing stigma and discrimination, and

  20. Development of a National Occupational Exposure Survey and Database associated with NIOSH hazard surveillance initiatives.

    PubMed

    Boiano, J M; Hull, R D

    2001-02-01

    NIOSH pioneered hazard surveillance in the workplace by designing and conducting the 1972 to 1974 National Occupational Hazard Survey (NOHS), the 1981 to 1983 National Occupational Exposure Survey (NOES), and the 1984 to 1989 National Occupational Health Survey of Mining (NOHSM). The databases developed from these three on-site surveys represent unique resources for associating potential chemical, physical and biological agents with industries and occupational groups. The data have been a primary source of information for NIOSH, regulatory agencies, health professionals, researchers, and labor organizations in establishing priorities for prevention strategies that include medical and engineering interventions, development of occupational standards, and the identification of research needs. Recognizing that the data from these surveys are becoming dated, a multidisciplinary team comprising members from various NIOSH research divisions was established to develop a hazard surveillance strategy for the Institute, including options for a national hazard surveillance survey and database. The proposed new hazard survey builds on lessons learned from the previous surveys, seeks opportunities to incorporate existing data from other sources, expands the scope of industries and hazards, and takes advantage of advances in data gathering, processing and dissemination technology. This article presents current considerations and recommendations for a new hazard survey and database.

    At the Black Bear prep plant (near Wharncliffe, WV, USA) the clean coal from the spirals traditionally reported to high-frequency screens, which removed high-ash clay fines. Screens have inherent inefficiencies that allow clean coal to report to the screen underflow. The goal of this project was to capture the maximum amount of spiral clean coal while still removing the high-ash clay material found in the spiral product. The reduction of the circulating load and plant downtime for unscheduled maintenance were projected as additional benefits. After the plant upgrade, the maintenance related to the high frequency screens was eliminated and an additional 2.27 tons per hour (tph) of fine coal was recovered, which resulted in a payback period of less than one year. The article was adapted from a paper presented at Coal Prep 2007 in April 2007, Lexington, KY, USA. 1 ref., 1 fig., 1 tab.

    Context Self-report questionnaires are an important method of evaluating lifespan health, exercise, and health-related quality of life (HRQL) outcomes among elite, competitive athletes. Few instruments, however, have undergone formal characterization of their psychometric properties within this population. Objective To evaluate the validity and reliability of a novel health and exercise questionnaire, the Trojan Lifetime Champions (TLC) Health Survey. Design Descriptive laboratory study. Setting A large National Collegiate Athletic Association Division I university. Patients or Other Participants A total of 63 university alumni (age range, 24 to 84 years), including former varsity collegiate athletes and a control group of nonathletes. Intervention(s) Participants completed the TLC Health Survey twice at a mean interval of 23 days with randomization to the paper or electronic version of the instrument. Main Outcome Measure(s) Content validity, feasibility of administration, test-retest reliability, parallel-form reliability between paper and electronic forms, and estimates of systematic and typical error versus differences of clinical interest were assessed across a broad range of health, exercise, and HRQL measures. Results Correlation coefficients, including intraclass correlation coefficients (ICCs) for continuous variables and κ agreement statistics for ordinal variables, for test-retest reliability averaged 0.86, 0.90, 0.80, and 0.74 for HRQL, lifetime health, recent health, and exercise variables, respectively. Correlation coefficients, again ICCs and κ, for parallel-form reliability (ie, equivalence) between paper and electronic versions averaged 0.90, 0.85, 0.85, and 0.81 for HRQL, lifetime health, recent health, and exercise variables, respectively. Typical measurement error was less than the a priori thresholds of clinical interest, and we found minimal evidence of systematic test-retest error. We found strong evidence of content validity, convergent

    Introduction Adolescents form two-thirds of our population. This is a unique group of people with special needs. Our survey aims to identify the lifestyle and behavioral patterns in this group of people and subsequently come up with issues that warrant special attention. Methods A survey was performed in various schools of Karachi. Data collection was done via a face-to-face interview based on a structured, pre-tested questionnaire. Participants included all willing persons between 12–19 years of age. Results Most adolescents with lifestyle issues fell in the age group of 16–18 years. Females were more depressed than males and had more sleep problems. Substance abuse and other addictions were documented more in males. Watching television or listening to music was stated as the most common late night activity (61.8%) and therefore was also referred to as the contributory factor for less than eight hours of sleep each day. (58.9%) of the respondents are getting less than eight hours of sleep daily. (41.5%) of the respondents who felt depressed sought treatment for it. Quite a few of them were also indulged in substance abuse and other addictions. Only (16.8%) of the respondents opined that physical activity is essential for health. Thirty-five adolescents out of all the respondents were smoking cigarettes currently, whereas 7% of the respondents chewed paan (areca nut). Peer pressure was the most common reason (37.1%) to start smoking. Conclusion Adolescents need to be treated as a distinct segment of our population and it is important to realize and address their health and lifestyle problems. Inadequate sleep, depression and smoking were the leading unhealthy behaviours among the respondents. Families can play an important role to help these adolescents live a healthier life. Further research studies should be carried out to highlight issues of concern and their possible solutions in this population. PMID:20886001

  15. Surveys on sexual health: recent developments and future directions

    Wellings, K.; Cleland, J.

    2001-01-01

    The increasingly widespread adoption of the term sexual health reflects a move away from the medicalisation of this specialty. The focus has shifted from clinical practice to lifestyle and behaviour; from clinician to client, and from treatment to prevention. This article discusses these themes, identifying their implications for sexual health research. Recent times have seen, for example, a growing number of studies combining biological and behavioural measures conducted by interdisciplinary teams able to combine biomedical measurements of morbidity with insights into the subjective interpretations of symptoms and consequences. Considerable progress has been made, too, in mounting community based studies, and much has been achieved in gaining compliance and refining sampling methods. Integrated sexual health services, encompassing more than contraceptive or prophylactic service provision, have provided the impetus to investigation of the costs and benefits of coordinated family planning and genitourinary medicine services. Despite its broader focus, there remain opportunities for sexual health research to expand its remit. Studies to date may have focused too narrowly on pathological, to the neglect of health enhancing, consequences of sexual behaviour. Key Words: surveys; sexual health PMID:11463921

    Pain-related-evoked potentials (PREP) is an established electrophysiological method to evaluate the signal transmission of electrically stimulated A-delta fibres. Although prerequisite for its clinical use, test-retest-reliability and side-to-side differences of bilateral stimulation in healthy subjects have not been examined yet. We performed PREP twice within 3 to 14days in 33 healthy subjects bilaterally by stimulating the dorsal hand. Detection (DT) and pain thresholds (PT) after electrical stimulation, the corresponding pain ratings, latencies of P0, N1, P1 and N2 components and the corresponding amplitudes were assessed. Impact of electrically induced pain intensity, age, sex, and arm length on PREP was analysed. MANOVA, t-Test, interclass correlation coefficient (ICC), standard error of measurement (SEM), smallest real difference (SRD), Bland-Altmann-Analysis as well as ANCOVA were used for statistical analysis. Measurement from both sides on both days resulted in mean N1-latencies from 142.39 ±18.12ms to 144.03 ±16.62ms and in mean N1P1-amplitudes from 39.04 ±12.26μV to 40.53 ±12.9μV. Analysis of a side-to-side effect showed for the N1-latency a F-value of 0.038 and for the N1P1-amplitude of 0.004 (p >0.8). We found intraclass correlation coefficients (ICC) from 0.88 to 0.93 and a standard error of measurement (SEM) < 10% of mean values for all measurements concerning the N1-Latency and N1P1-amplitude. Intraclass correlation coefficients, standard error of measurement and Bland-Altman-Analyses revealed excellent test-retest-reliability for N1-latency and N1P1-amplitude without systematic error and there was no side-to-side effect on PREP. N1-latency (r=0.35, p <0.05) and N1P1-amplitude (r=-0.45, p <0.05) correlated with age and additionally N1-latency correlated with arm length (r=0.45, p<0.001). In contrast, pain intensity during the stimulation had no effect on both N1-latency and N1P1-amplitude. In summary, PREP showed high test

    Pre-exposure prophylaxis (PrEP) is considered an effective biomedical approach for HIV prevention. However, there is limited understanding of PrEP uptake among racially/ethnically and socioeconomically diverse young men who have sex with men (YMSM). This study examined attitudes and perceptions toward PrEP uptake among YMSM by conducting semistructured interviews with a sample (N = 100) of YMSM in New York City. Thematic analysis was employed to explore key issues related to attitudes and perceptions toward PrEP utilization. Findings suggest that self-perceived risk for HIV transmission, enjoying unprotected sex, and being in a romantic relationship were associated with PrEP uptake. The most prominent barriers to PrEP uptake included costs, adherence regimen, and access. In summary, these findings underscore the importance of addressing behavioral and structural factors in maximizing the effectiveness of PrEP. In addition, PrEP implementation programs ought to consider the role of social and structural challenges to PrEP uptake and adherence among YMSM. PMID:25915697

    Massively Parallel (Next Generation) Sequencing (MPS) technologies have recently been proven useful and successful in typing various markers relevant in forensic genetics, such as STRs, SNPs and mitochondrial genomes. Early studies investigated self-developed DNA libraries, commercially supplied kits are currently being made available to allow a smoother and gradual implementation of such technologies in forensic laboratories. The ForenSeq™ DNA Signature Prep Kit (Illumina, CA) is the first commercially available STR kit that can be used on the MiSeq FGx™ (Illumina, CA) benchtop high-throughput sequencer. This kit allows the simultaneous typing of 59 STRs and up to 172 SNPs in a single reaction and presents a short library preparation protocol adapted to contemporary forensic requirements. In this study, we evaluated the beta version of the ForenSeq DNA Signature Prep Kit MiSeq FGx system by investigating reproducibility, sensitivity, mixtures, concordance, casework-type and aDNA samples and found it to perform successfully, proving to be a robust method for future forensic applications. MPS brings the possibility of complex multiplexing, high sensitivity and sequencing resolution to forensics; however, the need for consensual directions on databasing, data storage and nomenclature must be taken into consideration.

    The Continuous Electron Beam Accelerator Facility (CEBAF) in Newport News, Virginia is a new accelerator designed to produce 4 GeV 200 micro-amp continuous wave beams for nuclear physics research. It consists of two superconducting linacs each accelerating electrons by 400 MeV and linked by arcs allowing five pass recirculation. These linacs form the straight sections in a racetrack shaped accelerator contained in over 1.3 km of tunnel. The beam lines will consist of 42 superconducting accelerating cryomodules (in the linacs only), over 400 dipoles, 650 quadrupoles, and 100 sextupoles, most of the which are concentrated in the two arc sections of the machine. It is here that the single beam fine from the linacs is split into five beams of offering energy and transported to the opposite linac where it is recombined into a single beam to again pass through a linac and receive additional acceleration. These recirculation arcs are designed to maintain beam quality through a lattice which is achromatic, isochronous and whose length is equal to a multiple number of RF wavelengths. The short term relative alignment tolerances coupled with the beam fine design reflect the beam quality issues while absolute positioning determines the range of adjustment needed to match the RF phase in the linac segments. The alignment techniques which use a monumented control network as a reference, are designed to position stacked magnets and their support systems to these tolerances. Specialized procedures were tailored from existing hardware and software systems to address each phase or step of the alignment process. This allowed a relatively rapid expansion of alignment services at a new laboratory where surveying support was not seriously addressed until more then one third of the enclosure had been built.

    2015-01-01

    Purpose of review To describe the use of Tenofovir/Emtricitabine (Truvada) as prevention for exposure to HIV (PrEP) infection in the US. The use of PrEP and the challenges of implementation are very instructive as other countries adopt this intervention and it becomes a fundamental part of worldwide efforts for HIV prevention and much can be learned from the first three years in the US. Recent findings Randomized trials and demonstration projects have shown the benefits of PrEP for men and women who are at risk for HIV. Numerous studies have showed that the level of prevention is excellent when the drug is taken at least four times weekly, once adequate levels are obtained. However, adherence remains a critical issue as well as tailoring delivery models for specific populations. Six recent studies are discussed which support excellent efficacy and significantly support PrEP as a means of prevention. These projects have shown high acceptance of PrEP with excellent adherence by individuals demonstrated by those at risk remaining free of HIV over extended periods of time. Summary The US faces three significant challenges in scaling up PrEP. The first challenge in implementation in the US has is to get individuals to recognize the actual risks that their behaviors represent and to engage with providers to address these issues. The second challenge is getting a population of providers to recognize the exact same issues and offer PrEP in a compassionate, non judgmental fashion. The third challenge is identifying the set of providers and locations to scale up the response in a timely, cost effective fashion. PMID:26599165

    Measuring scientific development is a difficult task. Different metrics have been put forward to evaluate scientific development; in this paper we explore a metric that uses the number of peer-reviewed, and when available non-peer-reviewed, research articles as an indicator of development in the field of astronomy. We analyzed the available publication record, using the Smithsonian Astrophysical Observatory/NASA Astrophysics Database System, by country affiliation in the time span between 1950 and 2011 for countries with a gross national income of less than 14,365 USD in 2010. This represents 149 countries. We propose that this metric identifies countries in ''astronomical development'' with a culture of research publishing. We also propose that for a country to develop in astronomy, it should invest in outside expert visits, send its staff abroad to study, and establish a culture of scientific publishing. Furthermore, we propose that this paper may be used as a baseline to measure the success of major international projects, such as the International Year of Astronomy 2009.

    The double-blind phase of the randomized ANRS IPERGAY trial, evaluating sexual activity-based oral HIV pre-exposure prophylaxis (PrEP), was conducted among high-risk men who have sex with men (MSM). Results showed an 86% (95% CI: 40-98) relative reduction in HIV incidence among participants with tenofovir disoproxil fumarate-emtricitabine vs. placebo. The present pooled analysis aimed to analyze (i) participants' adherence to the prescribed treatment and/or condom use during sexual intercourse and (ii) sexual behavior during the double-blind phase of the study. Four hundred MSM were enrolled in the trial. Every 2 months they completed online questionnaires collecting sexual behavior and PrEP adherence data regarding their most recent sexual intercourse. A total of 2232 questionnaires (M0-M24) were analyzed. Changes over time were evaluated using a mixed model accounting for multiple measures. Irrespective of sexual partner and practice type, on average, 42.6% (min: 32.1-max: 45.8%) reported PrEP use only during their most recent episode of sexual intercourse; 29% (22.9-35.6%) reported both PrEP and condom use; 11.7% (7.2-18.9%) reported condom-use only, and 16.7% (10.8-29.6%) reported no PrEP or condom use with no significant change during the study. Scheduled (i.e., correct) PrEP use was reported on average by 59.0% (47.2-68.5%) of those reporting PrEP use during their most recent sexual intercourse. Overall, 70.3% (65.3-79.4%) and 69.3% (58.3-75.4%) of participants reported, respectively, condomless anal and condomless receptive anal intercourse during their most recent sexual encounter without significant change during follow-up. Overall, on average 83.3% (min: 70.4-max: 89.2%) of participants protected themselves by PrEP intake or condom use or both during the trial, and no increase in at-risk sexual practices was observed.

Overall, 70.3% (65.3–79.4%) and 69.3% (58.3–75.4%) of participants reported, respectively, condomless anal and condomless receptive anal intercourse during their most recent sexual encounter without significant change during follow-up. Overall, on average 83.3% (min: 70.4–max: 89.2%) of participants protected themselves by PrEP intake or condom use or both during the trial, and no increase in at-risk sexual practices was observed. None of these indicators showed significant trend during the follow-up, although we found a tendency

    A compact radiometric survey system, named KURAMA (Kyoto University RAdiation MApping system), has been developed as a response to the nuclear disaster of Fukushima Daiichi nuclear power plant. KURAMA is based on GPS (Global Positioning System) and network technology, and intended for the realtime data accumulation of multiple mobile monitoring stations, such as monitoring cars. KURAMA now serves for the car-borne surveys in Fukushima and surrounding prefectures by the Japanese Government and local authorities. An outline of KURAMA and discussions on car-borne γ-ray surveys using KURAMA are introduced.

    2016-01-01

    Background HIV Pre-Exposure Prophylaxis (PrEP) has been found to be efficacious in preventing HIV acquisition among seronegative individuals in a variety of risk groups, including men who have sex with men and people who inject drugs. To date, however, it remains unclear how socio-cultural norms (e.g., attitudes towards HIV; social understandings regarding HIV risk practices) may influence the scalability of future PrEP interventions. The objective of this study is to assess how socio-cultural norms may influence the implementation and scalability of future HIV PrEP interventions in Vancouver, Canada. Methods We conducted 50 interviews with young men (ages 18–24) with a variety of HIV risk behavioural profiles (e.g., young men who inject drugs; MSM). Interviews focused on participants’ experiences and perceptions with various HIV interventions and policies, including PrEP. Results While awareness of PrEP was generally low, perceptions about the potential personal and public health gains associated with PrEP were interconnected with expressions of complex and sometimes conflicting social norms. Some accounts characterized PrEP as a convenient form of reliable protection against HIV, likening it to the female birth control pill. Other accounts cast PrEP as a means to facilitate ‘socially unacceptable’ behaviour (e.g., promiscuity). Stigmatizing rhetoric was used to position PrEP as a tool that could promote some groups’ proclivities to take ‘risks’. Conclusion Stigma regarding ‘risky’ behaviour and PrEP should not be underestimated as a serious implementation challenge. Pre-implementation strategies that concomitantly aim to improve knowledge about PrEP, while addressing associated social prejudices, may be key to effective implementation and scale-up.

    We elicited attitudes about, and service access preferences for, daily oral antiretroviral pre-exposure prophylaxis (PrEP) from urban, African-American young men and women, ages 18-24 years, at risk for HIV transmission through their sexual and drug-related behaviors participating in eight mixed-gender and two MSM-only focus groups in Atlanta, Georgia. Participants reported substantial interest in PrEP associated with its perceived cost, effectiveness, and ease of accessing services and medication near to their homes or by public transportation. Frequent HIV testing was a perceived benefit. Participants differed about whether risk-reduction behaviors would change, and in which direction; and whether PrEP use would be associated with HIV stigma or would enhance the reputation for PrEP users. This provides the first information about the interests, concerns, and preferences of young adult African Americans that can be used to inform the introduction of PrEP services into HIV prevention efforts for this critical population group.

    2017-03-01

    Development of validated physics surveys on various topics is important for investigating the extent to which students master those concepts after traditional instruction and for assessing innovative curricula and pedagogies that can improve student understanding significantly. Here, we discuss the development and validation of a conceptual multiple-choice survey related to magnetism suitable for introductory physics courses. The survey was developed taking into account common students’ difficulties with magnetism concepts covered in introductory physics courses found in our investigation and the incorrect choices to the multiple-choice questions were designed based upon those common student difficulties. After the development and validation of the survey, it was administered to introductory physics students in various classes in paper-pencil format before and after traditional lecture-based instruction in relevant concepts. We compared the performance of students on the survey in the algebra-based and calculus-based introductory physics courses before and after traditional lecture-based instruction in relevant magnetism concepts. We discuss the common difficulties of introductory physics students with magnetism concepts we found via the survey. We also administered the survey to upper-level undergraduates majoring in physics and PhD students to benchmark the survey and compared their performance with those of traditionally taught introductory physics students for whom the survey is intended. A comparison with the base line data on the validated magnetism survey from traditionally taught introductory physics courses and upper-level undergraduate and PhD students discussed in this paper can help instructors assess the effectiveness of curricula and pedagogies which is especially designed to help students integrate conceptual and quantitative understanding and develop a good grasp of the concepts. In particular, if introductory physics students’ average

    The Apollo program has been the most complex exploration ever attempted by man, requiring extensive research, development, and engineering in most of the sciences before the leap through space could begin. Photography has been used at each step of the way to document the efforts and activities, isolate mistakes, reveal new phenomena, and to record much that cannot be seen by the human eye. At the same time, the capabilities of photography were extended because of the need of meeting space requirements. The results of this work have been applied to community planning and ecology, for example, as well as to space and engineering. Special uses of standard equipment, modifications and new designs, as well as film combinations that indicate actual or potential ecological problems are described.

    We report an outline and a current status of developing a small, all-aluminum made telescope for Nano-JASMINE. Nano-JASMINE is a nano-size astrometry satellite that is to be launched in 2008 and will demonstrate some key technologies required for JASMINE (Japan Astrometry Satellite Mission for Infrared Exploration) in a real space environment. It also measures absolute positions of bright stars (z< 8 mag) with accuracies about 1 milli-arcsecond in a few years mission. It has a Ritchey-Chretien type telescope with a 5-cm effective aperture, a 167-cm focal length and a field of view of 0.5x0.5 degree. The telescope only occupies a volume about 15x12x12 cm, and weighs two kilograms or less. Almost all of the structures and the optical elements of the telescope, including two aspherical mirrors three flat mirrors and a dual-angled flat mirror that combines the beam from a relative angle of 99.5 degrees into the primary mirror, are made out of aluminum alloy, being figured by diamond turning machines. The Bread Board Model (BBM) of the telescope is found to be achieving a diffraction-limited performance at room temperature.

  2. A Survey and Recent Development of Lunar Gravity Assist

    Penzo, Paul A.

    2000-01-01

    Earth's moon is the largest in the solar system relative to its parent body, the Earth, and can have significant effect on the path of a spacecraft flying close by. This effect, when planned to benefit a specific mission, is called lunar gravity assist (LGA) , and assumes that one aims the spacecraft towards the Moon in such a way that the Moon's gravitational pull will alter the spacecraft's course in a favorable manner. The first application of LGA was in the Apollo program, where the command and lunar modules (and astronauts) were propelled to the Moon such that, if no additional course changes were made, they would swing around the backside of the Moon at a certain altitude and be flung back to Earth to enter the atmosphere at a specified location in the Pacific ocean. This LGA was an essential element saving the lives of the astronauts on Apollo 13. This paper will illustrate the basic mechanics of gravity assist, and list the many applications where it has been used effectively over the past 30 some years. These include missions to the sun and Earth libration points, redirecting a spacecraft from one of these point to a comet encounter, and enhancing payloads by providing an energy boost by the Moon. More recently, studies and actual missions have shown the benefits of LGA in: (1) assisting lunar capture, (2) repositioning geosynchronous communications satellites, (3) boosting spacecraft to Earth escape and departure to planets and other solar system bodies, and (4) allowing small spacecraft to be launched as secondary payloads and released into almost a random orbit from which each may depart and maneuver in space with gravity assists from the Earth and Moon to perform a specific planetary or other mission. This latter application is a recent development by the author and is being applied in 2002 and later years, with piggyback flights on the Ariane 5 which launches comsats to GEO.

    The harm produced by tobacco products is a result of frequent use of a highly toxic product. Reducing the adverse public health impact of tobacco products might be most effectively achieved by reducing the likelihood of their use and the toxicity of the products. Products that retain some characteristics of cigarettes, but have been altered with the intention of reducing toxicity have been referred to as modified risk tobacco products or potential reduced exposure products (MRTP/PREPS). Evaluation of their content, emission, and toxicity is discussed in other articles in this special issue. Here, we discuss the methodology that has been used to examine the likelihood of abuse or addiction. Abuse liability assessment (ALA) methodology has been used by the Food and Drug Administration (FDA) and other drug regulatory agencies world-wide for decades to assess the risks posed by a wide variety of pharmacologically active substances. ALA is routinely required among other evaluations of safety during the premarket assessment of new drugs, and is continually adapted to meet the challenges posed by new drug classes and drug formulations. In the 2009 law giving FDA regulation over tobacco products, FDA is now required to evaluate new tobacco products including MRTP/PREPs to determine their risk for abuse and toxicity at the population level. This paper describes the traditional tools and methods of ALA that can be used to evaluate new tobacco and nicotine products including MRTP/PREPs. Such ALA data could contribute to the scientific foundation on which future public policy decisions are based. PMID:19959676

    A method was developed for the detection of Listeria monocytogenes in food. The method is based on real-time PCR using hydrolysis probes (5' Nuclease). This advanced PCR method was designed to reduce the time necessary to achieve results from PCR reactions and to enable the user to monitor the amplification of the PCR product simultaneously, in real-time. After DNA isolation using the BIOTECON foodproof ShortPrep II Kit designed for the rapid preparation of L. monocytogenes DNA for direct use in PCR, the real-time detection of L. monocytogenes DNA is carried out using the foodproof Listeria monocytogenes Detection Kit. The kit provides primers and hydrolysis probes for sequence-specific detection, convenient premixed reagents, and controls for reliable interpretation of results. For the internal comparison study, three different foods (soft cheese, coalfish, and smoked ham) were analyzed, chosen from the 15 food groups recommended by the AOAC Research Institute for detection of L. monocytogenes. From each food, 20 samples were inoculated with a low level (1-10 CFU/25 g) and 20 samples with a high level (10-50 CFU/25 g) of L. monocytogenes. Additionally, five nonspiked samples were prepared from each food. Depending on the matrix, the food samples were examined with the test kits and compared with the cultural methods according to the U.S. Food and Drug Administration's Bacteriological Analytical Manual or the U.S. Department of Agriculture/Food Safety and Inspection Service Microbiology Laboratory Guidebook.

    Pre-exposure prophylaxis (PrEP) is a viable HIV prevention strategy but risk compensation could undermine potential benefits. There are limited data that examine this phenomenon outside of clinical trials. We conducted a qualitative analysis of counseling notes from the San Francisco site of the US PrEP demonstration project to assess how men who have sex with men used PrEP as a prevention strategy and its impact on their sexual practices. Four major themes emerged from our analysis of 130 distinct notes associated with 26 participants. Prevention strategy decision-making was dynamic, often influenced by the context and perceived risk of a sexual encounter. Counselors noted that participants used PrEP in conjunction with other health promotion strategies like condoms, asking about HIV status of their sex partners, and seroadaptation. With few exceptions, existing risk reduction strategies were not abandoned upon initiation of PrEP. Risk-taking behavior was 'seasonal' and fluctuations were influenced by various personal, psychosocial, and health-related factors. PrEP also helped relieve anxiety regarding sex and HIV, particularly among serodiscordant partners. Understanding sexual decision-making and how PrEP is incorporated into existing prevention strategies can help inform future PrEP implementation efforts.

    Daily oral pre-exposure prophylaxis (PrEP) is the use of antiretroviral drugs by HIV-negative people to prevent HIV infection. WHO released new guidelines in 2015 recommending PrEP for all populations at substantial risk of HIV infection. To prepare these guidelines, we conducted a systematic review of values and preferences among populations that might benefit from PrEP, women, heterosexual men, young women and adolescent girls, female sex workers, serodiscordant couples, transgender people and people who inject drugs, and among healthcare providers who may prescribe PrEP. A comprehensive search strategy reviewed three electronic databases of articles and HIV-related conference abstracts (January 1990-April 2015). Data abstraction used standardised forms to categorise by population groups and relevant themes. Of 3068 citations screened, 76 peer-reviewed articles and 28 conference abstracts were included. Geographic coverage was global. Most studies (N = 78) evaluated hypothetical use of PrEP, while 26 studies included individuals who actually took PrEP or placebo. Awareness of PrEP was low, but once participants were presented with information about PrEP, the majority said they would consider using it. Concerns about safety, side effects, cost and effectiveness were the most frequently cited barriers to use. There was little indication of risk compensation. Healthcare providers would consider prescribing PrEP, but need more information before doing so. Findings from a rapidly expanding evidence base suggest that the majority of populations most likely to benefit from PrEP feel positively towards it. These same populations would benefit from overcoming current implementation challenges with the shortest possible delay.

    Student experience surveys have become increasingly popular to probe various aspects of processes and outcomes in higher education, such as measuring student perceptions of the learning environment and identifying aspects that could be improved. This paper reports on a particular survey for evaluating individual experiments that has been developed over some 15 years as part of a large national Australian study pertaining to the area of undergraduate laboratories-Advancing Science by Enhancing Learning in the Laboratory. This paper reports on the development of the survey instrument and the evaluation of the survey using student responses to experiments from different institutions in Australia, New Zealand and the USA. A total of 3153 student responses have been analysed using factor analysis. Three factors, motivation, assessment and resources, have been identified as contributing to improved student attitudes to laboratory activities. A central focus of the survey is to provide feedback to practitioners to iteratively improve experiments. Implications for practitioners and researchers are also discussed.

    The 1997 Houston Pre-Freshman Enrichment Program (PREP) was conducted at the campus of the University of Houston-Downtown from June 9 to July 25, 1997. Program participants were recruited from the Greater Houston Area. All participants were identified as high-achieving students with an interest in learning about the engineering and science professions. The goal of the program was to better prepare our pre-college youth prior to entering college as mathematics, science and engineering majors. The program participants were middle school and high school students from the Aldine, Alief, Channel View, Clear Creek, Cypress-Fairbanks, Fort Bend, Galena Park, Houston, Humble, Katy, Klein, North Forest, Pasadena, Private, and Spring Branch Independent School Districts. Of the 194 students starting the program, 165 students were from economically and socially disadvantage groups under-represented in the engineering and science professions, and 118 of the 194 were women. Our First Year group for 1997 composed of 96% minority and women students. Second and Third Year students combined were 96% minority or women. With financial support from the Center for Computational Sciences and Advanced Distributed Simulation, the Fourth Year Program was added to PREP this year. Twelve students completed the program (83% minority or women).

    The technology to collect brain imaging and physiological measures has become portable and ubiquitous, opening the possibility of large-scale analysis of real-world human imaging. By its nature, such data is large and complex, making automated processing essential. This paper shows how lack of attention to the very early stages of an EEG preprocessing pipeline can reduce the signal-to-noise ratio and introduce unwanted artifacts into the data, particularly for computations done in single precision. We demonstrate that ordinary average referencing improves the signal-to-noise ratio, but that noisy channels can contaminate the results. We also show that identification of noisy channels depends on the reference and examine the complex interaction of filtering, noisy channel identification, and referencing. We introduce a multi-stage robust referencing scheme to deal with the noisy channel-reference interaction. We propose a standardized early-stage EEG processing pipeline (PREP) and discuss the application of the pipeline to more than 600 EEG datasets. The pipeline includes an automatically generated report for each dataset processed. Users can download the PREP pipeline as a freely available MATLAB library from http://eegstudy.org/prepcode.

    Background Antiretroviral treatment for HIV-infection before immunologic decline (early ART) and pre-exposure chemoprophylaxis (PrEP) can prevent HIV transmission, but routine adoption of these practices by clinicians has been limited. Methods Between September and December 2013, healthcare practitioners affiliated with a regional AIDS Education and Training Center in New England were invited to complete online surveys assessing knowledge, beliefs and practices regarding early ART and PrEP. Multivariable models were utilized to determine characteristics associated with prescribing intentions and practices. Results Surveys were completed by 184 practitioners. Respondent median age was 44 years, 58% were female, and 82% were white. Among ART-prescribing clinicians (61% of the entire sample), 64% were aware that HIV treatment guidelines from the Department of Health and Human Services recommended early ART, and 69% indicated they would prescribe ART to all HIV-infected patients irrespective of immunologic status. However, 77% of ART-prescribing clinicians would defer ART for patients not ready to initiate treatment. Three-fourths of all respondents were aware of guidance from the U.S. Centers for Disease Control and Prevention recommending PrEP provision, 19% had prescribed PrEP, and 58% of clinicians who had not prescribed PrEP anticipated future prescribing. Practitioners expressed theoretical concerns and perceived practical barriers to prescribing early ART and PrEP. Clinicians with higher percentages of HIV-infected patients (aOR 1.16 per 10% increase in proportion of patients with HIV-infection, 95% CI 1.01–1.34) and infectious diseases specialists (versus primary care physicians; aOR 3.32, 95% CI 0.98–11.2) were more likely to report intentions to prescribe early ART. Higher percentage of HIV-infected patients was also associated with having prescribed PrEP (aOR 1.19, 95% CI 1.06–1.34), whereas female gender (aOR 0.26, 95% CI 0.10–0.71) was associated

    Objective To develop and evaluate survey questions that assess processes of care relevant to Patient-Centered Medical Homes (PCMHs). Research Design We convened expert panels, reviewed evidence on effective care practices and existing surveys, elicited broad public input, and conducted cognitive interviews and a field test to develop items relevant to PCMHs that could be added to the CAHPS® Clinician & Group (CG-CAHPS) 1.0 Survey. Surveys were tested using a two-contact mail protocol in 10 adult and 33 pediatric practices (both private and community health centers) in Massachusetts. A total of 4,875 completed surveys were received (overall response rate of 25%). Analyses We calculated the rate of valid responses for each item. We conducted exploratory factor analyses and estimated item-to-total correlations, individual and site level reliability, and correlations among proposed multi-item composites. Results Ten items in four new domains (Comprehensiveness, Information, Self-Management Support, and Shared Decision-Making) and four items in two existing domains (Access and Coordination of Care) were selected to be supplemental items to be used in conjunction with the adult CG-CAHPS 1.0 survey. For the child version, four items in each of two new domains (Information and Self-Management Support) and five items in existing domains (Access, Comprehensiveness-Prevention, Coordination of Care) were selected. Conclusions This study provides support for the reliability and validity of new items to supplement the CG-CAHPS 1.0 survey to assess aspects of primary care that are important attributes of Patient-Centered Medical Homes.

    2016-11-01

    Study Design Survey study. Objective To determine the global perspective on controversial aspects of sacral fracture classifications. Methods While developing the AOSpine Sacral Injury Classification System, a survey was sent to all members of AOSpine and AOTrauma. The survey asked four yes-or-no questions to help determine the best way to handle controversial aspects of sacral fractures in future classifications. Chi-square tests were initially used to compare surgeons' answers to the four key questions of the survey, and then the data was modeled through multivariable logistic regression analysis. Results A total of 474 surgeons answered all questions in the survey. Overall 86.9% of respondents felt that the proposed hierarchical nature of injuries was appropriate, and 77.8% of respondents agreed that that the risk of neurologic injury is highest in a vertical fracture through the foramen. Almost 80% of respondents felt that the separation of injuries based on the integrity of L5-S1 facet was appropriate, and 83.8% of surgeons agreed that a nondisplaced sacral U fracture is a clinically relevant entity. Conclusion This study determines the global perspective on controversial areas in the injury patterns of sacral fractures and demonstrates that the development of a comprehensive and universally accepted sacral classification is possible.

    2016-01-01

    Optimizing access to HIV pre-exposure prophylaxis (PrEP), an evidence-based HIV prevention resource, requires expanding healthcare providers’ adoption of PrEP into clinical practice. This qualitative study explored PrEP providers’ firsthand experiences relative to six commonly-cited barriers to prescription—financial coverage, implementation logistics, eligibility determination, adherence concerns, side effects, and anticipated behavior change (risk compensation)—as well as their recommendations for training PrEP-inexperienced providers. U.S.-based PrEP providers were recruited via direct outreach and referral from colleagues and other participants (2014–2015). One-on-one interviews were conducted in person or by phone, transcribed, and analyzed. The sample (n = 18) primarily practiced in the Northeastern (67%) or Southern (22%) U.S. Nearly all (94%) were medical doctors (MDs), most of whom self-identified as infectious disease specialists. Prior experience prescribing PrEP ranged from 2 to 325 patients. Overall, providers reported favorable experiences with PrEP implementation and indicated that commonly anticipated problems were minimal or manageable. PrEP was covered via insurance or other programs for most patients; however, pre-authorization requirements, laboratory/service provision costs, and high deductibles sometimes presented challenges. Various models of PrEP care and coordination with other providers were utilized, with several providers highlighting the value of clinical staff support. Eligibility was determined through joint decision-making with patients; CDC guidelines were commonly referenced but not considered absolute. Patient adherence was variable, with particularly strong adherence noted among patients who had actively sought PrEP (self-referred). Providers observed minimal adverse effects or increases in risk behavior. However, they identified several barriers with respect to accessing and engaging PrEP candidates. Providers offered

    for NASA's Jet Propulsion Laboratory in Pasadena, California. An upward-looking ultraviolet video camera placed in the SR-71's nosebay studied a variety of celestial objects in wavelengths that are blocked to ground-based astronomers. Earlier in its history, Dryden had a decade of past experience at sustained speeds above Mach 3. Two YF-12A aircraft and an SR-71 designated as a YF-12C were flown at the center between December 1969 and November 1979 in a joint NASA/USAF program to learn more about the capabilities and limitations of high-speed, high-altitude flight. The YF-12As were prototypes of a planned interceptor aircraft based on a design that later evolved into the SR-71 reconnaissance aircraft. Dave Lux was the NASA SR-71 project manger for much of the decade of the 1990s, followed by Steve Schmidt. Developed for the USAF as reconnaissance aircraft more than 30 years ago, SR-71s are still the world's fastest and highest-flying production aircraft. The aircraft can fly at speeds of more than 2,200 miles per hour (Mach 3+, or more than three times the speed of sound) and at altitudes of over 85,000 feet. The Lockheed Skunk Works (now Lockheed Martin) built the original SR-71 aircraft. Each aircraft is 107.4 feet long, has a wingspan of 55.6 feet, and is 18.5 feet high (from the ground to the top of the rudders, when parked). Gross takeoff weight is about 140,000 pounds, including a possible fuel weight of 80,280 pounds. The airframes are built almost entirely of titanium and titanium alloys to withstand heat generated by sustained Mach 3 flight. Aerodynamic control surfaces consist of all-moving vertical tail surfaces, ailerons on the outer wings, and elevators on the trailing edges between the engine exhaust nozzles. The two SR-71s at Dryden have been assigned the following NASA tail numbers: NASA 844 (A model), military serial 61-7980 and NASA 831 (B model), military serial 61-7956. From 1990 through 1994, Dryden also had another 'A' model, NASA 832, military

  8. Hydrostatic, uniaxial, and triaxial compression tests on unpoled "Chem-prep" PZT 95/5-2Nb ceramic within temperature range of -55 to 75 degrees C.

    Sandia is currently developing a lead-zirconate-titanate ceramic 95/5-2Nb (or PNZT) from chemically prepared ('chem-prep') precursor powders. Previous PNZT ceramic was fabricated from the powders prepared using a 'mixed-oxide' process. The specimens of unpoled PNZT ceramic from batch HF803 were tested under hydrostatic, uniaxial, and constant stress difference loading conditions within the temperature range of -55 to 75 C and pressures to 500 MPa. The objective of this experimental study was to obtain mechanical properties and phase relationships so that the grain-scale modeling effort can develop and test its models and codes using realistic parameters. The stress-strain behavior of 'chem-prep' PNZT under different loading paths was found to be similar to that of 'mixed-oxide' PNZT. The phase transformation from ferroelectric to antiferroelectric occurs in unpoled ceramic with abrupt increase in volumetric strain of about 0.7 % when the maximum compressive stress, regardless of loading paths, equals the hydrostatic pressure at which the transformation otherwise takes place. The stress-volumetric strain relationship of the ceramic undergoing a phase transformation was analyzed quantitatively using a linear regression analysis. The pressure (P{sub T1}{sup H}) required for the onset of phase transformation with respect to temperature is represented by the best-fit line, P{sub T1}{sup H} (MPa) = 227 + 0.76 T (C). We also confirmed that increasing shear stress lowers the mean stress and the volumetric strain required to trigger phase transformation. At the lower bound (-55 C) of the tested temperature range, the phase transformation is permanent and irreversible. However, at the upper bound (75 C), the phase transformation is completely reversible as the stress causing phase transformation is removed.

    From an online survey of current technological capabilities of US undergraduate nursing programs, we found almost universal use of Microsoft Windows-based computers and Microsoft Office Suite software. Netscape and Microsoft Internet Explorer were the most popular browsers for Internet access. The survey also assessed faculty preferences for end-of-life care teaching materials and found that nurse educators preferred simple easy-to-use tools provided on CD-ROM or the Internet, with instructions provided via CD-ROM, the Internet, and demonstration workshops. Our findings have numerous implications for the development of electronic teaching materials for nursing.

  14. Saying 'No' to PrEP research in Malawi: what constitutes 'failure' in offshored HIV prevention research?

    Peterson, Kristin; Folayan, Morenike Oluwatoyin; Chigwedere, Edward; Nthete, Evaristo

    2015-12-01

    Between 2004 and 2005, the first multi-sited clinical trial tested whether an existing, marketed antiretroviral drug, Tenofovir (TDF), could prevent HIV transmission. Referred to as pre-exposure prophylaxis (PrEP), most of these trial sites prematurely closed down. Two sites located in Cambodia and Cameroon received international media attention. But little attention was drawn to sites in Malawi and Nigeria, where university ethicists and research scientists extensively debated PrEP. This article focuses on events that took place in Malawi where there was a prolonged dispute over the scientific rationales of PrEP and not trial specific ethics referred to as 'bioethics'. Specifically, the article discusses debates pertaining to three PrEP trial protocols that were refused ethics approval in Malawi between 2004 and 2009. It is argued that HIV science debates in Malawi are embedded in postcolonial politics--geopolitical histories and state and household economic dispossessions that have created the structural possibilities for Malawi to become an offshore destination for HIV clinical research. As such, ethics in this case does not pertain to trial or bioethical 'failures'. Rather, ethics is located at the scale of imperial relations that give rise to multiple, often invisible, research concerns and constraints.

    Singer, Sara J; Moore, Scott C; Meterko, Mark; Williams, Sandra

    2012-08-01

    Despite urgent need for innovation, adaptation, and change in health care, few tools enable researchers or practitioners to assess the extent to which health care facilities perform as learning organizations or the effects of initiatives that require learning. This study's objective was to develop and test a short-form Learning Organization Survey to fill this gap. The authors applied exploratory factor analysis and confirmatory factor analysis to data from Veterans Health Administration personnel to derive a short-form survey and then conducted further confirmatory factor analysis and factor invariance testing on additional Veterans Health Administration data to evaluate the short form. Results suggest that a 27-item, 7-factor survey (2 environmental factors, 1 on leadership, and 4 on concrete learning processes and practices) reliably measures key features of organizational learning, allowing researchers to evaluate theoretical propositions about organizational learning, its antecedents, and outcomes and enabling managers to assess and enhance organizations' learning capabilities and performance.

    We discuss the development of a research-based conceptual multiple-choice survey of magnetism. We also discuss the use of the survey to investigate gender differences in students' difficulties with concepts related to magnetism. We find that while there was no gender difference on the pre-test. However, female students performed significantly worse than male students when the survey was given as a post-test in traditionally taught calculus-based introductory physics courses with similar results in both the regular and honors versions of the course. In the algebra-based courses, the performance of female and male students has no statistical difference on the pre-test or the post-test.

The fundamental nature of the survey has not changed: the focus is still on medium- and large-sized establishments which employ at least 100 degreed S Es in R D. The 1990 Survey contains data which cover about 18% of all establishments eligible to participate, encompassing approximately 18% of all eligible employees. As in the last three years, the survey sample constitutes a fairly good representation of the entire population of eligible establishments on the basis of business sector, geographic location, and size. Maturity-based analyses of salaries for some 34,000 nonsupervisory researchers are provided, as are job content-based analyses of more than 27,000 individual contributors and almost 5000 first level supervisors and division directors. Compensation policies and practices data are provided for 102 establishments, and benefits plans for 62 establishments are analyzed.

    Objective and Rationale: The objective of this paper is to present a comprehensive, yet brief, flowchart type of overview of the salient literature describing the key chronological steps involved in developing “pencil and paper,” self-report, health-related survey instruments — particularly survey instruments which endeavor to measure abstract construct such as “quality of life,” “disability,” or “productivity.” This overview was designed to serve as a convenient reference guide for individuals who need to understand the basics of the whole process. Because it does not describe any of the steps in detail, the flowchart will likely be most useful to individuals who have at least some prior familiarity with the concepts, procedures and analyses mentioned, yet are not fully “expert” in this topic area. In short, this overview is not actually meant to be a “checklist” of key steps; brief explanations are included in order to remind the — at least somewhat — initiated user of the concepts mentioned, without the reader necessarily having to look them up elsewhere. Design: This is a distillation of the salient survey-development literature into a procedural overview flowchart. Method: This overview was a distillation of several authoritative sources in the literature covering the key areas of questionnaire development and psychometric theory. The overview flowchart was constructed in the form of 5 chronological, developmental phases, which formed the overall framework: Part 1: Defining the Intended Purpose of the Survey Instrument Part 2: Item Generation Part 3: Item Reduction Part 4: Psychometric Testing and Further Item Reduction Part 5: Final Revision of the Prototype Into a Useable Survey Instrument (Questionnaire). The flow-chart was assessed for face and content validity by 3 questionnaire-development experts. Results and Conclusion: This paper presented a fairly comprehensive, yet brief, flowchart type of overview of the salient

    As part of the National HIV Behavioral Surveillance System among men who have sex with men (MSM) in Denver, Colorado, we assessed knowledge of pre-exposure prophylaxis (PrEP); willingness to use PrEP; and potential changes in risk behaviors among HIV-negative participants reporting sexual activity with a male partner in the preceding 12 months. We examined knowledge of PrEP before (2008) and after (2011) results of the iPrEx trial were available. Of the 425 participants in the 2008 sample, 91 (21 %) were aware of PrEP compared to 131 (28 %) of the 461 participants in the 2011 sample (adjusted prevalence ratio: 1.43, 95 % confidence interval: 1.18, 1.72). Despite the increase in 2011, few MSM in Denver were aware of PrEP. Educating high-risk MSM about the potential utility of PrEP as an adjunct to other effective prevention methods is needed when considering the addition of PrEP to the HIV prevention arsenal.

    The Savannah River National Laboratory (SRNL) has developed prototype equipment to demonstrate remote surveying of Inner and Outer DOE Standard 3013 containers for fixed and transferable contamination in accordance with DOE Standard 3013 and 10 CFR 835 Appendix B. When fully developed the equipment will be part of a larger suite of equipment used to package material in accordance with DOE Standard 3013 at the Pit Disassembly and Conversion Project slated for installation at the Savannah River Site. The prototype system consists of a small six-axis industrial robot with an end effector consisting of a force sensor, vacuum gripper and a three fingered pneumatic gripper. The work cell also contains two alpha survey instruments, swipes, swipe dispenser, and other ancillary equipment. An external controller interfaces with the robot controller, survey instruments and other ancillary equipment to control the overall process. SRNL is developing automated equipment for the Pit Disassembly and Conversion (PDC) Project that is slated for the Savannah River Site (SRS). The equipment being developed is automated packaging equipment for packaging plutonium bearing materials in accordance with DOE-STD-3013-2004. The subject of this paper is the development of a prototype Radiological Survey Station (RSS). Other automated equipment being developed for the PDC includes the Bagless transfer System, Outer Can Welder, Gantry Robot System (GRS) and Leak Test Station. The purpose of the RSS is to perform a frisk and swipe of the DOE Standard 3013 Container (either inner can or outer can) to check for fixed and transferable contamination. This is required to verify that the contamination levels are within the limits specified in DOE-STD-3013-2004 and 10 CFR 835, Appendix D. The surface contamination limit for the 3013 Outer Can (OC) is 500 dpm/100 cm2 (total) and 20 dpm/100 cm2 (transferable). This paper will concentrate on the RSS developments for the 3013 OC but the system for the

    2016-01-01

    Background Two-dimensional (2D) spatially selective radiofrequency (RF) pulses may be used to excite restricted volumes. By incorporating a "pencil beam" 2D pulse into a T2-Prep, one may create a "2D-T2-Prep" that combines T2-weighting with an intrinsic outer volume suppression. This may particularly benefit parallel imaging techniques, where artefacts typically originate from residual foldover signal. By suppressing foldover signal with a 2D-T2-Prep, image quality may therefore improve. We present numerical simulations, phantom and in vivo validations to address this hypothesis. Methods A 2D-T2-Prep and a conventional T2-Prep were used with GRAPPA-accelerated MRI (R = 1.6). The techniques were first compared in numerical phantoms, where per pixel maps of SNR (SNRmulti), noise, and g-factor were predicted for idealized sequences. Physical phantoms, with compartments doped to mimic blood, myocardium, fat, and coronary vasculature, were scanned with both T2-Preparation techniques to determine the actual SNRmulti and vessel sharpness. For in vivo experiments, the right coronary artery (RCA) was imaged in 10 healthy adults, using accelerations of R = 1,3, and 6, and vessel sharpness was measured for each. Results In both simulations and phantom experiments, the 2D-T2-Prep improved SNR relative to the conventional T2-Prep, by an amount that depended on both the acceleration factor and the degree of outer volume suppression. For in vivo images of the RCA, vessel sharpness improved most at higher acceleration factors, demonstrating that the 2D-T2-Prep especially benefits accelerated coronary MRA. Conclusion Suppressing outer volume signal with a 2D-T2-Prep improves image quality particularly well in GRAPPA-accelerated acquisitions in simulations, phantoms, and volunteers, demonstrating that it should be considered when performing accelerated coronary MRA.

    Abstract Although the Food and Drug Administration (FDA) approved oral Truvada for pre-exposure prophylaxis (PrEP) for women at risk of HIV infection in the US in July 2012, and the Centers for Disease Control and Prevention (CDC) issued guidance for clinicians to provide PrEP to women “at substantial risk of HIV acquisition” in May 2014, there remain no clinical trial data on efficacy among US women, and there is a dearth of research on knowledge, attitudes, and likelihood of use of PrEP among them. We conducted a qualitative focus group (FG) study with 144 at-risk women in six US cities between July and September 2013, including locations in the Southern US, where HIV infections among women are most prevalent. FG questions elicited awareness of PrEP, attitudes about administration and uptake, and barriers to and facilitators of use. Women expressed anger at the fact that they had not heard of PrEP prior to the study, but once informed most found it attractive. PrEP was seen as additional, not substitute protection to condoms, and participants suggested several dissemination strategies to meet the diverse needs of women. Key barriers to PrEP uptake included distrust of the medical system, stigma, and cost. Findings suggest that US women view PrEP as an important prevention option, assuming side effects and the cost to the consumer are minimal, the efficacy of the drug is reasonable, and PrEP is delivered by trusted providers in trusted venues.

    Accumulation of amyloid-β peptide (Aβ), the neurotoxic peptide implicated in the pathogenesis of Alzheimer's disease (AD), has been shown in brain mitochondria of AD patients and of AD transgenic mouse models. The presence of Aβ in mitochondria leads to free radical generation and neuronal stress. Recently, we identified the presequence protease, PreP, localized in the mitochondrial matrix in mammalian mitochondria as the novel mitochondrial Aβ-degrading enzyme. In the present study, we examined PreP activity in the mitochondrial matrix of the human brain's temporal lobe, an area of the brain highly susceptible to Aβ accumulation and reactive oxygen species (ROS) production. We found significantly lower hPreP activity in AD brains compared with non-AD age-matched controls. By contrast, in the cerebellum, a brain region typically spared from Aβ accumulation, there was no significant difference in hPreP activity when comparing AD samples to non-AD controls. We also found significantly reduced PreP activity in the mitochondrial matrix of AD transgenic mouse brains (Tg mAβPP and Tg mAβPP/ABAD) when compared to non-transgenic aged-matched mice. Furthermore, mitochondrial fractions isolated from AD brains and Tg mAβPP mice had higher levels of 4-hydroxynonenal, an oxidative product, as compared with those from non-AD and nonTg mice. Accordingly, activity of cytochrome c oxidase was significantly reduced in the AD mitochondria. These findings suggest that decreased PreP proteolytic activity, possibly due to enhanced ROS production, contributes to Aβ accumulation in mitochondria leading to the mitochondrial toxicity and neuronal death that is exacerbated in AD. Clearance of mitochondrial Aβ by PreP may thus be of importance in the pathology of AD.

  11. Collection development and outsourcing in academic health sciences libraries: a survey of current practices.

    1999-01-01

    Academic health sciences libraries in the United States and Canada were surveyed regarding collection development trends, including their effect on approval plan and blanket order use, and use of outsourcing over the past four years. Results of the survey indicate that serials market forces, budgetary constraints, and growth in electronic resources purchasing have resulted in a decline in the acquisition of print items. As a result, approval plan use is being curtailed in many academic health sciences libraries. Although use of blanket orders is more stable, fewer than one-third of academic health sciences libraries report using them currently. The decline of print collections suggests that libraries should explore cooperative collection development of print materials to ensure access and preservation. The decline of approval plan use and the need for cooperative collection development may require additional effort for sound collection development. Libraries were also surveyed about their use of outsourcing. Some libraries reported outsourcing cataloging and shelf preparation of books, but none reported using outsourcing for resource selection. The reason given most often for outsourcing was that it resulted in cost savings. As expected, economic factors are driving both collection development and outsourcing practices. PMID:10219477

    Initiatives designed to prevent teen pregnancy are often based on adult perceptions of the negative aspects of a teen birth. Qualitative research has revealed that teens may perceive positive rewards associated with teen parenting. These perceptions have not yet been examined through survey research. The theory of reasoned action proposes that individuals assess the costs and rewards prior to engaging in a behavior and provides a framework for the development of a survey instrument designed to measure adolescent thoughts about the costs and rewards of the teen parenting experience. This manuscript describes the development and testing of a quantitative survey instrument designed to measure adolescents' perceptions. Pretesting, piloting, exploratory factor analysis, and a variety of reliability and validity measures were used to determine the value of the measure. The thoughts on teen parenting survey (TTPS) demonstrates an alpha level of .90. The TTPS yields a cumulative score of teen perceptions about the impact of a teen birth during the adolescent years that may be used to assess youth beliefs, correlated with demographic data, used to identify teens at risk for pregnancy/parenting, or provide a pretest/posttest to assess the effectiveness of interventions designed to foster realistic attitudes toward teen parenting.

    This project incorporates radiation survey training into a real-time video radiation detection system, thus providing a practical perspective for the radiation worker on efficient performance of radiation surveys. Regular surveys to evaluate radiation levels are necessary not only to recognize potential radiological hazards but also to keep the radiation exposure as low as reasonably achievable. By developing and implementing an instructional learning system using a real-time radiation survey training video showing specific categorization of work elements, radiation workers trained with this system demonstrated better radiation survey practice.

    We† provide an overview of the Model Based Systems Engineering (MBSE) language, tool, and methodology being used in our development of the Operational Plan for Large Synoptic Survey Telescope (LSST) operations. LSST's Systems Engineering (SE) team is using a model-based approach to operational plan development to: 1) capture the topdown stakeholders' needs and functional allocations defining the scope, required tasks, and personnel needed for operations, and 2) capture the bottom-up operations and maintenance activities required to conduct the LSST survey across its distributed operations sites for the full ten year survey duration. To accomplish these complimentary goals and ensure that they result in self-consistent results, we have developed a holistic approach using the Sparx Enterprise Architect modeling tool and Systems Modeling Language (SysML). This approach utilizes SysML Use Cases, Actors, associated relationships, and Activity Diagrams to document and refine all of the major operations and maintenance activities that will be required to successfully operate the observatory and meet stakeholder expectations. We have developed several customized extensions of the SysML language including the creation of a custom stereotyped Use Case element with unique tagged values, as well as unique association connectors and Actor stereotypes. We demonstrate this customized MBSE methodology enables us to define: 1) the rolls each human Actor must take on to successfully carry out the activities associated with the Use Cases; 2) the skills each Actor must possess; 3) the functional allocation of all required stakeholder activities and Use Cases to organizational entities tasked with carrying them out; and 4) the organization structure required to successfully execute the operational survey. Our approach allows for continual refinement utilizing the systems engineering spiral method to expose finer levels of detail as necessary. For example, the bottom-up, Use Case

    Internationally, efforts to increase student interest in science, technology, engineering, and mathematics (STEM) careers have been on the rise. It is often the goal of such efforts that increased interest in STEM careers should stimulate economic growth and enhance innovation. Scientific and educational organizations recommend that efforts to interest students in STEM majors and careers begin at the middle school level, a time when students are developing their own interests and recognizing their academic strengths. These factors have led scholars to call for instruments that effectively measure interest in STEM classes and careers, particularly for middle school students. In response, we leveraged the social cognitive career theory to develop a survey with subscales in science, technology, engineering, and mathematics. In this manuscript, we detail the six stages of development of the STEM Career Interest Survey. To investigate the instrument's reliability and psychometric properties, we administered this 44-item survey to over 1,000 middle school students (grades 6-8) who primarily were in rural, high-poverty districts in the southeastern USA. Confirmatory factor analyses indicate that the STEM-CIS is a strong, single factor instrument and also has four strong, discipline-specific subscales, which allow for the science, technology, engineering, and mathematics subscales to be administered separately or in combination. This instrument should prove helpful in research, evaluation, and professional development to measure STEM career interest in secondary level students.

    Rehabilitation of patients with anterior conoid teeth may present a challenge for the clinician, especially when trying to mimic the nature with composite resins. This clinical report exemplifies how a patient with conoid upper lateral incisors was rehabilitated with minimally invasive adhesive restorations. Following diagnostic wax-up and cosmetic mock-up, no-prep veneers and ceramic fragments (partial veneers) were constructed with feldspathic porcelain. This restorative material presents excellent reproduction of the optical properties of the dental structure, especially at minimal thicknesses. In this paper, the details about the treatment are described. A very pleasing outcome was achieved, confirming that minimally invasive adhesive restorations are an excellent option for situations in which the dental elements are healthy, and can be modified exclusively by adding material and the patient does not want to suffer any wear on the teeth.

    Urban development creates multiple stressors that can degrade stream ecosystems by changing stream hydrology, water quality, and physical habitat. Contaminants, habitat destruction, and increasing streamflow variability resulting from urban development have been associated with the disruption of biological communities, particularly the loss of sensitive aquatic biota. Understanding how algal, invertebrate, and fish communities respond to these physical and chemical stressors can provide important clues as to how streams should be managed to protect stream ecosystems as a watershed becomes increasingly urbanized. The U.S. Geological Survey continues to lead monitoring efforts and scientific studies on the effects of urban development on stream ecosystems in metropolitan areas across the United States.

    The 1996 Houston Pre-freshman Enrichment Program (PREP) was conducted on the campus of the University of Houston-Downtown from June 10 to August 1, 1996. Program Participants were recruited from the Greater Houston area. All participants were identified as high achieving students with an interest in learning about the engineering and science professions. The goal of the program was to better prepare our pre-college youth prior to entering college as mathematics, science and engineering majors. The program participants were middle school and high school students from the Aldine, Alief, Channel View, Crockett, Cypress-Fairbanks, Fort Bend, Galena Park, Houston, Humble, Katy, Klein, North Forest, Pasadena, Private, and Spring Branch Independent School Districts. Of the 197 students starting the program, 170 completed, 142 students were from economically and socially disadvantage groups underrepresented in the engineering and science professions, and 121 of the 197 were female. Our First Year group for 1996 composed of 96% minority and women students. Our Second and Third Year students were 100% and 93.75% minority or women respectively. This gave an overall minority and female population of 93.75%. This year, special efforts were again made to recruit students from minority groups, which caused a significant increase in qualified applicants. However, due to space limitations, 140 applicants were rejected. Investigative and discovery learning were key elements of PREP. The academic components of the program included Algebraic Structures, Engineering, Introduction to Computer Science, Introduction to Physics, Logic and Its Application to Mathematics, Probability and Statistics, Problem Solving Seminar using computers and PLATO software, SAT Preparatory Seminars, and Technical Writing.

    The development of decommissioning technologies, including those for evaluation of the radioactivity inventory and the radiation dose, and a site investigation plan are needed to ensure safe decommissioning. The residual radioactivity should be measured and analysed to release a site for unrestricted use. The methods used for measurement of residual radioactivity have an effect on the workers' manpower and the decommissioning cost. So the development of the measurement methods of residual radioactivity with guidelines for a radiation survey and site investigation is needed to prepare for the future decommissioning of commercial Nuclear Power plants. The major considerations and characteristics of the parameters related to the decision of measurements points have been reviewed. The methods for controlling uncertainty and techniques to determine whether the measurement results achieve the survey objectives have been established.

    The National Aviation Operational Monitoring Service (NAOMS) was a research project under NASA s Aviation Safety Program during the years from 2000 to 2005. The purpose of this project was to develop a methodology for gaining reliable information on changes over time in the rates-of-occurrence of safety-related events as a means of assessing the safety of the national airspace. The approach was a scientifically designed survey of the operators of the aviation system concerning their safety-related experiences. This report presents the results of the methodology developed and a demonstration of the NAOMS concept through a survey of nearly 20,000 randomly selected air-carrier pilots. Results give evidence that the NAOMS methodology can provide a statistically sound basis for evaluating trends of incidents that could compromise safety. The approach and results are summarized in the report and supporting documentation and complete analyses of results are presented in 14 appendices.

    2012-01-01

    Background Recruitment to randomized controlled trials is known to be challenging. It is important to understand and identify predictors of good or poor accrual to a clinical trial so that appropriate strategies can be put in place to overcome these problems and facilitate successful trial completion. We have developed a survey tool to establish the recruitment experience of clinical teams regarding facilitators and barriers to recruitment in a clinical trial and describe herein the method of developing the questionnaire. Methods A literature search was conducted to identify studies that have explored facilitators and barriers to recruitment, and a list of potential factors affecting recruitment to a clinical trial was generated. These factors were categorized in terms relating to the (i) trial, (ii) site, (iii) patient, (iv) clinical team, (v) information and consent and (vi) study team. A list was provided for responders to grade these factors as weak, intermediate or strong facilitators or barriers to recruitment. Results A web-based survey questionnaire was developed. This survey was designed to establish the recruitment experience of clinical teams with regard to the perceived facilitators and barriers to recruitment, to identify strategies applied to overcome these problems, and to obtain suggestions for change in the organization of future trials. The survey tool can be used to assess the recruitment experience of clinical teams in a single/multicenter trial in any clinical setting or speciality involving adults or children either in an ongoing trial or at trial completion. The questionnaire is short, easy to administer and to complete, with an estimated completion time of 11 minutes. Conclusions We have presented a robust methodology for developing this survey tool that provides an evidence-based list of potential factors that can affect recruitment to a clinical trial. We recommend that all clinical trialists should consider using this tool with

    The U.S. Department of Energy (DOE) has adopted a goal to generate 20% of the nation’s electricity from wind power by 2030. Achieving this “20% Wind Scenario” in 2030 requires acceleration of the current rate of wind project development. Offshore wind resources contribute substantially to the nation’s wind resource, yet to date no offshore wind turbines have been installed in the U.S. Progress developing offshore wind projects has been slowed by technological challenges, uncertainties about impacts to the marine environment, siting and permitting challenges, and viewshed concerns. To address challenges associated with siting and permitting, Pacific Northwest National Laboratory (PNNL) surveyed offshore wind project developers about siting and project development processes, their experience with the environmental permitting process, and the role of coastal and marine spatial planning (CMSP) in development of the offshore wind industry. Based on the responses to survey questions, we identify several priority recommendations to support offshore wind development. Recommendations also include considerations for developing supporting industries in the U.S. and how to use Coastal and Marine Spatial Planning (CMSP) to appropriately consider ocean energy among existing ocean uses. In this report, we summarize findings, discuss the implications, and suggest actions to improve the permitting and siting process.

    Background and Objective Conscientious objection to abortion, clinicians’ refusal to perform legal abortions because of their religious or moral beliefs, has been the subject of increasing debate among bioethicists, policymakers, and public health advocates in recent years. Conscientious objection policies are intended to balance reproductive rights and clinicians’ beliefs. However, in practice, clinician objection can act as a barrier to abortion access–impinging on reproductive rights, and increasing unsafe abortion and related morbidity and mortality. There is little information about conscientious objection from a medical or public health perspective. A quantitative instrument is needed to assess prevalence of conscientious objection and to provide insight on its practice. This paper describes the development of a survey instrument to measure conscientious objection to abortion provision. Methods A literature review, and in-depth formative interviews with stakeholders in Colombia were used to develop a conceptual model of conscientious objection. This model led to the development of a survey, which was piloted, and then administered, in Ghana. Results The model posits three domains of conscientious objection that form the basis for the survey instrument: 1) beliefs about abortion and conscientious objection; 2) actions related to conscientious objection and abortion; and 3) self-identification as a conscientious objector. Conclusions The instrument is intended to be used to assess prevalence among clinicians trained to provide abortions, and to gain insight on how conscientious objection is practiced in a variety of settings. Its results can inform more effective and appropriate strategies to regulate conscientious objection. PMID:27736992

    The Wide-field Infrared Survey Explorer (WISE), a NASA Medium-Class Explorer (MIDEX) mission, is surveying the entire sky in four bands from 3.4 to 22 microns with a sensitivity hundreds to hundreds of thousands times better than previous all-sky surveys at these wavelengths. The single WISE instrument consists of a 40 cm three-mirror anastigmatic telescope, a two-stage solid hydrogen cryostat, a scan mirror mechanism, and reimaging optics giving 6" resolution (full-width-half-maximum). WISE was placed into a Sun-synchronous polar orbit on a Delta II 7320 launch vehicle on December 14, 2009. NASA selected WISE as a MIDEX in 2002 following a rigorous competitive selection process. To gain further confidence in WISE, NASA extended the development period one year with an option to cancel the mission if certain criteria were not met. MIDEX missions are led by the principal investigator who in this case delegated day-to-day management to the project manager. With a cost cap and relatively short development schedule, it was essential for all WISE partners to work seamlessly together. This was accomplished with an integrated management team representing all key partners and disciplines. The project was developed on budget and on schedule in spite of the need to surmount significant technical challenges. This paper describes our management approach, key challenges and critical decisions made. Results are described from a programmatic, technical and scientific point of view. Lessons learned are offered for projects of this type.

    Directors in substance use treatment programs are increasingly required to respond to external economic and socio-political pressures. Leadership practices that promote innovation can help offset these challenges. Using focus groups, factor analysis, and validation instruments, the current study developed and established psychometrics for the Survey of Transformational Leadership. In 2008, clinical directors were evaluated on leadership practices by 214 counselors within 57 programs in four U.S. regions. Nine themes emerged: integrity, sensible risk, demonstrates innovation, encourages innovation, inspirational motivation, supports others, develops others, delegates tasks, and expects excellence. Study implications, limitations and suggested future directions are discussed. Funding from NIDA. PMID:20509734

    Twenty community garden programs in upstate New York (representing 63 gardens) were surveyed to identify characteristics that may be useful to facilitate neighborhood development and health promotion. The most commonly expressed reasons for participating in gardens were access to fresh foods, to enjoy nature, and health benefits. Gardens in low-income neighborhoods (46%) were four times as likely as non low-income gardens to lead to other issues in the neighborhood being addressed; reportedly due to organizing facilitated through the community gardens. Additional research on community gardening can improve our understanding of the interaction of social and physical environments and community health, and effective strategies for empowerment, development, and health promotion.

    Introduction The extraordinary feat of proving the effectiveness of oral pre-exposure prophylaxis (PrEP) in clinical trials in different populations in a variety of settings may prove to have been easier than ensuring it is used well. Decision-makers must make difficult choices to realize the promise of antiretroviral prophylaxis for their countries. This paper outlines key economic, regulatory and distributive justice issues that must be addressed for effective and acceptable PrEP implementation. Discussion In considering the role that PrEP can play in combination prevention programmes, decision-makers must determine who can benefit most from PrEP, how PrEP can be provided safely and efficiently, and what kind of health system support will ensure successful implementation. To do this, they need contextualized information on disease burden by population, analyses of how PrEP services might best be delivered, and projections of the human resource and infrastructure requirements for each potential delivery model. There are cost considerations, varying cost-effectiveness results and regulatory challenges. The principles of ethics can inform thorny discussions about who should be prioritized for oral PrEP and how best to introduce it fairly. We describe the cost-effectiveness of PrEP in different populations at higher risk of HIV exposure, its price in low- and middle-income countries, and the current regulatory situation. We explore the principles of ethics that can inform resource allocation decision-making about PrEP anchored in distributive justice, at a time when universal access to antiretroviral treatment remains to be assured. We then highlight the role of advocacy in moving the PrEP agenda forward. Conclusions The time is ripe now for decisions about whether, how and for whom PrEP should be introduced into a country's HIV response. It has the potential to contribute significantly to high impact HIV prevention if it is tailored to those who can most benefit

    2013-01-01

    Many children eat a diet which supplies a higher than recommended amount of nonmilk extrinsic sugars and saturated fatty acids. The school setting is often targeted for nutrition intervention as many children consume food at school. In Scotland, attempts have been made to improve the nutritional content of food in schools and attention has now turned to food and drink available "beyond the school gate." This paper describes the development of a module on food and drink purchasing behaviour. The Food Purchasing Module was designed to collect data, for the first time, from a representative sample of children aged 8-16 years about food and drinks purchased on the way to/from school, during break time/free periods, and at lunchtime, from outlets around schools. Cognitive testing of the module highlighted that younger children find self-completion questionnaires problematic. Older children have fewer problems with self-completion questionnaires but many do not follow question routing, which has implications for the delivery of future surveys. Development of this survey module adds much needed evidence about effectively involving children in surveys. Further research exploring food and drinks purchased beyond the school gate is needed to continue to improve the nutritional quality of children's diets.

    In many settings, interventions targeting female sex workers (FSWs) could significantly reduce the overall transmission of HIV. To understand the role HIV pre-exposure prophylaxis (PrEP) could play in controlling HIV transmission amongst FSWs, it is important to understand how its impact compares with scaling-up condom use-one of the proven HIV prevention strategies for FSWs. It is important to remember that condoms also have other benefits such as reducing the incidence of sexually transmitted infections and preventing pregnancy. A dynamic deterministic model of HIV transmission amongst FSWs, their clients and other male partners (termed 'pimps') was used to compare the protection provided by PrEP for HIV-negative FSWs with FSWs increasing their condom use with clients and/or pimps. For different HIV prevalence scenarios, levels of pimp interaction, and baseline condom use, we estimated the coverage of PrEP that gives the same reduction in endemic FSW HIV prevalence or HIV infections averted as different increases in condom use. To achieve the same impact on FSW HIV prevalence as increasing condom use by 1%, the coverage of PrEP has to increase by >2%. The relative impact of PrEP increases for scenarios where pimps contribute to HIV transmission, but not greatly, and decreases with higher baseline condom use. In terms of HIV infections averted over 10 years, the relative impact of PrEP compared to condoms was reduced, with a >3% increase in PrEP coverage achieving the same impact as a 1% increase in condom use. Condom promotion interventions should remain the mainstay HIV prevention strategy for FSWs, with PrEP only being implemented once condom interventions have been maximised or to fill prevention gaps where condoms cannot be used.

    2015-01-01

    Although the negative impact of disruptive clinician behavior on quality health care delivery has gained attention recently, little systematic effort to address this issue has been reported. To facilitate empirical research to reduce disruptive clinician behaviors, an assessment tool (Johns Hopkins Disruptive Clinician Behavior Survey [JH-DCBS]) with 5 discrete subscales was developed using a 2-step design. First a pool of items was generated from focus group studies and the literature, and then a psychometric evaluation of the survey was conducted with a sample of clinicians (N = 1198) practicing in a large urban academic medical center. The results indicated that the tool was reliable (Cronbach α = .79-.91), showed high content validity (Content Validity Index = .97), and had significantly high correlations with theoretically selected variables. The study team concluded that the JH-DCBS provides a valid empirical assessment of disruptive behavior. Assessment results may be used to design strategies to improve the health and safety of practice environments.

    To better understand the impact of efforts to train more science teachers such as the PhysTEC Project and to help with early identification of future teachers, we are developing the survey of Perceptions of Teaching as a Profession (PTaP) to measure students' views of teaching as a career, their interest in teaching and the perceived climate of physics departments towards teaching as a profession. The instrument consists of a series of statements which require a response using a 5-point Likert-scale and can be easily administered online. The survey items were drafted by a team of researchers and physics teacher candidates and then reviewed by an advisory committee of 20 physics teacher educators and practicing teachers. We conducted 27 interviews with both teacher candidates and non-teaching STEM majors. The survey was refined through an iterative process of student interviews and item clarification until all items were interpreted consistently and answered for consistent reasons. In this presentation the preliminary results from the student interviews as well as the results of item analysis and a factor analysis on 900 student responses will be shared.

  5. Development of predictive mapping techniques for soil survey and salinity mapping

    NASA Astrophysics Data System (ADS)

    Elnaggar, Abdelhamid A.

    Conventional soil maps represent a valuable source of information about soil characteristics, however they are subjective, very expensive, and time-consuming to prepare. Also, they do not include explicit information about the conceptual mental model used in developing them nor information about their accuracy, in addition to the error associated with them. Decision tree analysis (DTA) was successfully used in retrieving the expert knowledge embedded in old soil survey data. This knowledge was efficiently used in developing predictive soil maps for the study areas in Benton and Malheur Counties, Oregon and accessing their consistency. A retrieved soil-landscape model from a reference area in Harney County was extrapolated to develop a preliminary soil map for the neighboring unmapped part of Malheur County. The developed map had a low prediction accuracy and only a few soil map units (SMUs) were predicted with significant accuracy, mostly those shallow SMUs that have either a lithic contact with the bedrock or developed on a duripan. On the other hand, the developed soil map based on field data was predicted with very high accuracy (overall was about 97%). Salt-affected areas of the Malheur County study area are indicated by their high spectral reflectance and they are easily discriminated from the remote sensing data. However, remote sensing data fails to distinguish between the different classes of soil salinity. Using the DTA method, five classes of soil salinity were successfully predicted with an overall accuracy of about 99%. Moreover, the calculated area of salt-affected soil was overestimated when mapped using remote sensing data compared to that predicted by using DTA. Hence, DTA could be a very helpful approach in developing soil survey and soil salinity maps in more objective, effective, less-expensive and quicker ways based on field data.

    Context: Public health practice is information-intensive and information-driven. Public health informatics is a nascent discipline, and most public health practitioners lack necessary skills in this area. Objective: To describe the staff development needs of local health departments (LHDs) related to informatics. Design: Data came from the 2015 Informatics Capacity and Needs Assessment Survey, conducted by Georgia Southern University in collaboration with the National Association of County & City Health Officials. Participants: A total of 324 LHDs from all 50 states completed the survey (response rate: 50%). Main Outcome Measure(s): Outcome measures included LHDs' specific staff development needs related to informatics. Predictors of interest included jurisdiction size and governance type. Results: Areas of workforce development and improvement in informatics staff of LHDs included using and interpreting quantitative data, designing and running reports from information systems, using and interpreting qualitative data, using statistical or other analytical software, project management, and using geographical information systems. Significant variation in informatics training needs exists depending on the size of the LHD population and governance type. Conclusion: Substantial training needs exist for LHDs across many areas of informatics ranging from very basic to specialized skills and are related to the size of LHD population and governance type.

    A theoretical background was established for the compilation process by dividing it into five phases and explaining the concepts and algorithms that underpin each. The five selected phases were lexical analysis, syntax analysis, semantic analysis, optimization, and code generation. Graph theoretical optimization techniques were presented, and approaches to code generation were described for both one-pass and multipass compilation environments. Following the initial tutorial sections, more than 20 tools that were developed to aid in the process of writing compilers were surveyed. Eight of the more recent compiler development aids were selected for special attention - SIMCMP/STAGE2, LANG-PAK, COGENT, XPL, AED, CWIC, LIS, and JOCIT. The impact of compiler development aids were assessed some of their shortcomings and some of the areas of research currently in progress were inspected.

    Background Inpatient discharge instructions are a mandatory requirement of the Centers for Medicare and Medicaid Services and Joint Commission on Accreditation of Healthcare Organizations. The instructions include all the information relevant to post-discharge patient care. Prior studies show that patients often cannot fully understand or remember all the instructions. To address this issue, we have previously conducted a pilot study in which pictographs were created through a participatory design process to facilitate the comprehension and recall of discharge instructions. Objective The main objective of this study was to verify the individual effectiveness of pictographs created through a participatory design process. Methods In this study, we included 20 pictographs developed by our group and 20 pictographs developed by the Robert Wood Johnson Foundation as a reference baseline for pictographic recognition. To assess whether the participants could recognize the meaning of the pictographs, we designed an asymmetrical pictograph–text label-linking test. Data collection lasted for 7 days after the email invitation. A total of 44 people accessed the survey site. We excluded 7 participants who completed less than 50% of the survey. A total of 719 answers from 37 participants were analyzed. Results The analysis showed that the participants recognized the pictographs developed in-house significantly better than those included in the study as a baseline (P< .001). This trend was true regardless of the participant’s gender, age, and education level. The results also revealed that there is a large variance in the quality of the pictographs developed using the same design process—the recognition rate ranged from below 50% to above 90%. Conclusions This study confirmed that the majority of the pictographs developed in a participatory design process involving a small number of nurses and consumers were recognizable by a larger number of consumers. The variance in

    2012-01-01

    Background Recent evidence has highlighted deficiencies in clinical trial protocols, having implications for many groups. Existing guidelines for randomized clinical trial (RCT) protocol content vary substantially and most do not describe systematic methodology for their development. As one of three prespecified steps for the systematic development of a guideline for trial protocol content, the objective of this study was to conduct a three-round Delphi consensus survey to develop and refine minimum content for RCT protocols. Methods Panellists were identified using a multistep iterative approach, met prespecified minimum criteria and represented key stakeholders who develop or use clinical trial protocols. They were asked to rate concepts for importance in a minimum set of items for RCT protocols. The main outcome measures were degree of importance (scale of 1 to 10; higher scores indicating higher importance) and level of consensus for items. Results were presented as medians, interquartile ranges, counts and percentages. Results Ninety-six expert panellists participated in the Delphi consensus survey including trial investigators, methodologists, research ethics board members, funders, industry, regulators and journal editors. Response rates were between 88 and 93% per round. Overall, panellists rated 63 of 88 concepts of high importance (of which 50 had a 25th percentile rating of 8 or greater), 13 of moderate importance (median 6 or 7) and 12 of low importance (median less than or equal to 5) for minimum trial protocol content. General and item-specific comments and subgroup results provided valuable insight for further discussions. Conclusions This Delphi process achieved consensus from a large panel of experts from diverse stakeholder groups on essential content for RCT protocols. It also highlights areas of divergence. These results, complemented by other empirical research and consensus meetings, are helping guide the development of a guideline for

    Preventing HIV infection in adolescents and young adults will require a multimodal, targeted approach including individual-directed behavioral risk reduction, community-level structural change, and biomedical interventions to prevent sexual transmission. Trials testing biomedical interventions to prevent HIV transmission will require special attention in this population due to the unique psychosocial as well as physiologic characteristics that differentiate them from older populations. For example, microbicide research will need to consider acceptability, dosing requirements, and co-infection rates that are unique to this population. Pre-exposure prophylaxis studies also will need to consider potential unique psychosocial issues such as sexual disinhibition and acceptability as well as unique pharmacokinetic parameters of antiretroviral agents. Vaccine trials also face unique issues with this population, including attitudes towards vaccines, risks related to false-positive HIV tests related to vaccine, and different immune responses based on more robust immunity. In this paper, we will discuss issues around implementing each of these biomedical prevention modalities in trials among adolescents and young adults to help to guide future successful research targeting this population.

    Optimal arterial opacification is crucial in imaging the pulmonary arteries using computed tomography (CT). This poses the challenge of precisely timing data acquisition to coincide with the transit of the contrast bolus through the pulmonary vasculature. The aim of this quality assurance exercise was to investigate if a change in CT pulmonary angiography (CTPA) scanning protocol resulted in improved opacification of the pulmonary arteries. Comparison was made between the smart prep protocol (SPP) and the test bolus protocol (TBP) for opacification in the pulmonary trunk. A total of 160 CTPA examinations (80 using each protocol) performed between January 2010 and February 2011 were assessed retrospectively. CT attenuation coefficients were measured in Hounsfield Units (HU) using regions of interest at the level of the pulmonary trunk. The average pixel value, standard deviation (SD), maximum, and minimum were recorded. For each of these variables a mean value was then calculated and compared for these two CTPA protocols. Minimum opacification of 200 HU was achieved in 98% of the TBP sample but only 90% of the SPP sample. The average CT attenuation over the pulmonary trunk for the SPP was 329 (SD = ±21) HU, whereas for the TBP it was 396 (SD = ±22) HU (P = 0.0017). The TBP also recorded higher maximum (P = 0.0024) and minimum (P = 0.0039) levels of opacification. This study has found that a TBP resulted in significantly better opacification of the pulmonary trunk than the SPP.

    2016-03-04

    We describe a novel solid-phase reversible sample-prep (SRS) platform that enables rapid sample preparation for concurrent proteome and N-glycome characterization for nearly all protein samples. SRS utilizes a uniquely functionalized, silica-based bead that has strong affinity toward proteins with minimal to no affinity for peptides and other small molecules. By leveraging this inherent size difference between proteins and peptides, SRS permits high-capacity binding of proteins, rapid removal of small molecules (detergents, metabolites, salts, peptides, etc.), extensive manipulation including enzymatic and chemical treatments on bead-bound proteins, and easy recovery of N-glycans and peptides. SRS was evaluated in a wide range of samples including glycoproteins, cell lysate, murine tissues, and human urine. SRS was also coupled to a quantitative strategy to investigate the differences between DU145 prostate cancer cells and its DIAPH3-silenced counterpart. Previous studies suggested that DIAPH3 silencing in DU145 induced transition to an amoeboid phenotype that correlated with tumor progression and metastasis. In this pilot study we identified distinct proteomic and N-glycomic alterations between them. A metastasis-associated tyrosine kinase receptor ephrin-type-A receptor (EPHA2) was highly up-regulated in DIAPH3-silenced cells, indicating a possible connection between EPHA2 and DIAPH3. Moreover, distinct alterations in the N-glycome were identified, suggesting cross-links between DIAPH3 and glycosyltransferase networks.

    The EarthLabs Climate project, an NSF-Discovery Research K12 program, has developed a suite of three online classroom-ready modules: Climate and the Cryosphere; Climate and the Carbon Cycle; and Climate and the Biosphere. The EarthLabs Climate project included week-long professional development workshops during June of 2012 and 2013 in Texas and Mississippi. Evaluation of the 2012 and 2013 workshops included participant self-reported learning levels in many areas of climate science. Teachers' answers indicated they had increased their understanding of the topics addressed in the workshops. However, the project team was interested in refining the evaluation process to determine exactly those areas of climate science in which participants increased content knowledge and ameliorated misconceptions. Therefore, to enhance the investigation into what teachers got out of the workshop, a pre-test/post-test design was implemented for 2013. In particular, the evaluation team was interested in discovering the degree to which participants held misconceptions and whether those beliefs were modified by attendance at the workshops. For the 2013 workshops, a registration survey was implemented that included the Climate Concept Inventory (a climate content knowledge quiz developed by the education research team for the project). The multiple-choice questions are also part of the pre/post student quiz used in classrooms in which the EarthLabs Climate curriculum was implemented. Many of the questions in this instrument assess common misconceptions by using them as distractors in the multiple choice options. The registration survey also asked respondents to indicate their confidence in their answer to each question, because, in addition to knowledge limitations, lack of confidence also can be a barrier to effective teaching. Data from the registration survey informed workshop managers of the topic content knowledge of participants, allowing fine-tuning of the professional development

    A US Air Force (USAF) Residential Energy Conservation Methodology was developed to compare USAF needs and available data to the procedures of the Residential Conservation Service (RCS) program as developed for general use by utility companies serving civilian customers. Attention was given to the data implications related to group housing, climatic data requirements, life-cycle cost analysis, energy saving modifications beyond those covered by RCS, and methods for utilizing existing energy consumption data in approaching the USAF survey program. Detailed information and summaries are given on the five subtasks of the program. Energy conservation alternatives are listed and the basic analysis techniques to be used in evaluating their thermal performane are described. (MCW)

    Ecological carbon sequestration refers to transfer and storage of atmospheric carbon in vegetation, soils, and aquatic environments to help offset the net increase from carbon emissions. Understanding capacities, associated opportunities, and risks of vegetated ecosystems to sequester carbon provides science information to support formulation of policies governing climate change mitigation, adaptation, and land-management strategies. Section 712 of the Energy Independence and Security Act (EISA) of 2007 mandates the Department of the Interior to develop a methodology and assess the capacity of our nation's ecosystems for ecological carbon sequestration and greenhouse gas (GHG) flux mitigation. The U.S. Geological Survey (USGS) LandCarbon Project is responding to the Department of Interior's request to develop a methodology that meets specific EISA requirements.

    Little is known about the general public's perception of the diagnosis of asthma and the impact of asthma on individuals, their families, and their communities. In addition, there appear to be no published survey instruments specifically designed to gain insights into how the general public perceives asthma. The purpose of this paper is to describe the development of such an instrument, the Chicago Community Asthma Survey (CCAS)-32. Development began with two qualitative steps. First, a review of the published literature guided the initial instrument construction (Step 1). Content domains were chosen based on clinical input and the Health Belief Model. Most items were derived from existing instruments. To assess content validity, cognitive interviews and expert reviews were conducted (Step 2). Items were added, modified, and deleted based on the information gathered at each of these steps. In the next step, item performance measurement (Step 3), testing of two samples provided quantitative data to further inform item reduction. Items with uniform correct responses or responses lacking in variability were excluded. The result of this three-step process was a 32-item survey of asthma knowledge, attitudes and perceptions, the CCAS-32. The introduction to the survey was subsequently modified to minimize respondent bias (Step 4). In conclusion, the CCAS-32 was constructed with input from experts in asthma and individuals from the Chicago area. The items in the CCAS-32 appear to have both face validity and acceptable performance characteristics.

    The potential for digital technologies to enhance students' mathematics learning is widely recognised, and use of computers and graphics calculators is now encouraged or required by secondary school mathematics curriculum documents throughout Australia. However, previous research indicates that effective integration of technology into classroom practice remains patchy, with factors such as teacher knowledge, confidence, experience and beliefs, access to resources, and participation in professional development influencing uptake and implementation. This paper reports on a large-scale survey of technology-related professional development experiences and needs of Queensland secondary mathematics teachers. Teachers who had participated in professional development were found to be more confident in using technology and more convinced of its benefits in supporting students' learning of mathematics. Experienced, specialist mathematics teachers in large metropolitan schools were more likely than others to have attended technology-related professional development, with lack of time and limited access to resources acting as hindrances to many. Teachers expressed a clear preference for professional development that helps them meaningfully integrate technology into lessons to improve student learning of specific mathematical topics. These findings have implications for the design and delivery of professional development that improves teachers' knowledge, understanding, and skills in a diverse range of contexts.

    The sintering behavior of Sandia chem-prep high field varistor materials was studied using techniques including in situ shrinkage measurements, optical and scanning electron microscopy and x-ray diffraction. A thorough literature review of phase behavior, sintering and microstructure in Bi{sub 2}O{sub 3}-ZnO varistor systems is included. The effects of Bi{sub 2}O{sub 3} content (from 0.25 to 0.56 mol%) and of sodium doping level (0 to 600 ppm) on the isothermal densification kinetics was determined between 650 and 825 C. At {ge} 750 C samples with {ge}0.41 mol% Bi{sub 2}O{sub 3} have very similar densification kinetics, whereas samples with {le}0.33 mol% begin to densify only after a period of hours at low temperatures. The effect of the sodium content was greatest at {approx}700 C for standard 0.56 mol% Bi{sub 2}O{sub 3} and was greater in samples with 0.30 mol% Bi{sub 2}O{sub 3} than for those with 0.56 mol%. Sintering experiments on samples of differing size and shape found that densification decreases and mass loss increases with increasing surface area to volume ratio. However, these two effects have different causes: the enhancement in densification as samples increase in size appears to be caused by a low oxygen internal atmosphere that develops whereas the mass loss is due to the evaporation of bismuth oxide. In situ XRD experiments showed that the bismuth is initially present as an oxycarbonate that transforms to metastable {beta}-Bi{sub 2}O{sub 3} by 400 C. At {approx}650 C, coincident with the onset of densification, the cubic binary phase, Bi{sub 38}ZnO{sub 58} forms and remains stable to >800 C, indicating that a eutectic liquid does not form during normal varistor sintering ({approx}730 C). Finally, the formation and morphology of bismuth oxide phase regions that form on the varistors surfaces during slow cooling were studied.

    This paper presents a more ecologically valid way of developing theory-based item questionnaires for measuring user experience. In this novel approach, items were generated using natural and domain-specific language of the research population, what seems to have made the survey much more sensitive to real experiences than theory-based ones. The approach was applied in a survey that measured car experience. Ten in-depth interviews were conducted with drivers inside their cars. The resulting transcripts were analysed with the aim of capturing their natural utterances for expressing their car experience. This analysis resulted in 71 categories of answers. For each category, one sentence was selected to serve as a survey-item. In an online platform, 538 respondents answered the survey. Data reliability, tested with Cronbach alpha index, was 0.94, suggesting a survey with highly reliable results to measure drivers' appraisals of their cars.

    Background A wide variety of ontologies relevant to the biological and medical domains are available through the OBO Foundry portal, and their number is growing rapidly. Integration of these ontologies, while requiring considerable effort, is extremely desirable. However, heterogeneities in format and style pose serious obstacles to such integration. In particular, inconsistencies in naming conventions can impair the readability and navigability of ontology class hierarchies, and hinder their alignment and integration. While other sources of diversity are tremendously complex and challenging, agreeing a set of common naming conventions is an achievable goal, particularly if those conventions are based on lessons drawn from pooled practical experience and surveys of community opinion. Results We summarize a review of existing naming conventions and highlight certain disadvantages with respect to general applicability in the biological domain. We also present the results of a survey carried out to establish which naming conventions are currently employed by OBO Foundry ontologies and to determine what their special requirements regarding the naming of entities might be. Lastly, we propose an initial set of typographic, syntactic and semantic conventions for labelling classes in OBO Foundry ontologies. Conclusion Adherence to common naming conventions is more than just a matter of aesthetics. Such conventions provide guidance to ontology creators, help developers avoid flaws and inaccuracies when editing, and especially when interlinking, ontologies. Common naming conventions will also assist consumers of ontologies to more readily understand what meanings were intended by the authors of ontologies used in annotating bodies of data.

    Background Development and targeting efforts by academic organizations to effectively promote research integrity can be enhanced if they are able to collect reliable data to benchmark baseline conditions, to assess areas needing improvement, and to subsequently assess the impact of specific initiatives. To date, no standardized and validated tool has existed to serve this need. Methods A web- and mail-based survey was administered in the second half of 2009 to 2,837 randomly selected biomedical and social science faculty and postdoctoral fellows at 40 academic health centers in top-tier research universities in the United States. Measures included the Survey of Organizational Research Climate (SORC) as well as measures of perceptions of organizational justice. Results Exploratory and confirmatory factor analyses yielded seven subscales of organizational research climate, all of which demonstrated acceptable internal consistency (Cronbach’s α ranging from 0.81 to 0.87) and adequate test-retest reliability (Pearson r ranging from 0.72 to 0.83). A broad range of correlations between the seven subscales and five measures of organizational justice (unadjusted regression coefficients ranging from .13 to .95) document both construct and discriminant validity of the instrument. Conclusions The SORC demonstrates good internal (alpha) and external reliability (test-retest) as well as both construct and discriminant validity. PMID:23096775

    Data on people flow has become increasingly important in the field of business, including the areas of marketing and public services. Although mobile phones enable a person's position to be located to a certain degree, it is a challenge to acquire sufficient data from people with mobile phones. In order to grasp people flow in its entirety, it is important to establish a practical method of reconstructing people flow from various kinds of existing fragmentary spatio-temporal data such as social survey data. For example, despite typical Person Trip Survey Data collected by the public sector showing the fragmentary spatio-temporal positions accessed, the data are attractive given the sufficiently large sample size to estimate the entire flow of people. In this study, we apply our proposed basic method to Japan International Cooperation Agency (JICA) PT data pertaining to developing cities around the world, and we propose some correction methods to resolve the difficulties in applying it to many cities and stably to infrastructure data.

    Background One of the greatest obstacles facing efforts to address quality of care in low and middle income countries is the absence of relevant and reliable data. This article proposes a methodology for creating a single “Quality Index” (QI) representing quality of maternal and neonatal health care based upon data collected as part of the Demographic and Health Survey (DHS) program. Methods Using the 2012 Indonesian Demographic and Health Survey dataset, indicators of quality of care were identified based on the recommended guidelines outlined in the WHO Integrated Management of Pregnancy and Childbirth. Two sets of indicators were created; one set only including indicators available in the standard DHS questionnaire and the other including all indicators identified in the Indonesian dataset. For each indicator set composite indices were created using Principal Components Analysis and a modified form of Equal Weighting. These indices were tested for internal coherence and robustness, as well as their comparability with each other. Finally a single QI was chosen to explore the variation in index scores across a number of known equity markers in Indonesia including wealth, urban rural status and geographical region. Results The process of creating quality indexes from standard DHS data was proven to be feasible, and initial results from Indonesia indicate particular disparities in the quality of care received by the poor as well as those living in outlying regions. Conclusions The QI represents an important step forward in efforts to understand, measure and improve quality of MNCH care in developing countries. PMID:27362354

    Data collected in contraceptive prevalence surveys for Korea, Sri Lanka, Thailand, Barbados, Colombia, Costa Rica, and Peru on how soon following childbirth menstruation returned provide the basis for national level estimates of the duration of postpartum amenorrhea. 2 somewhat different techniques are used for estimating median and mean durations of postpartum amenorrhea. The results are compared with information indicating patterns of breastfeeding. The analysis indicates considerable cross-national variation in the mean and median duration of postpartum amenorrhea and suggests that estimating postpartum amenorrhea from information on breastfeeding alone could be misleading. What is most striking about the results is how quickly postpartum amenorrhea appears to terminate in most of the countries. Only for Korean women is the median duration substantially above 1/2 a year. The results suggest that at least for most of the limited number of developing countries for which Westinghouse Contraceptive Prevalence Survey data are available, postpartum nonsusceptibility is providing protection against a new pregnancy for only a relatively short period following a birth for the majority of women. In all the countries with available data except Costa Rica, breastfeeding is close to universal, involving at least 90% of all children; in Costa Rica, only about 3/4 of children are ever breastfed. The average duration of breastfeeding is noticeably longer in the 3 Asian countries than in the Latin American ones.

    Among the many psychometric measures of sexual (dys)function, none is entirely suited to use in community surveys. Faced with the need to include a brief and non-intrusive measure of sexual function in a general population survey, a new measure was developed. Findings from qualitative research with men and women in the community designed to inform the conceptual framework for this measure are presented. Thirty-two semi-structured interviews with individuals recruited from a general practice, an HIV/AIDS charity, and a sexual problems clinic were conducted. From their accounts, 31 potential criteria of a functional sex life were identified. Using evidence from qualitative data and the existing literature, and applying a set of decision rules, the list was reduced to 13 (eight for those not in a relationship), and a further eight criteria were added to enable individuals to self-rate their level of function and indicate the severity of difficulties. These criteria constitute a conceptual framework that is grounded in participant perceptions; is relevant to all, regardless of sexual experience or orientation; provides opportunity to state the degree of associated distress; and incorporates relational, psychological, and physiological aspects. It provides the conceptual basis for a concise and acceptable measure of sexual function.

    Background HIV prevalence among female sex workers (FSWs) in India remains well above the national average. Pre-exposure prophylaxis (PrEP), a new HIV prevention technology, may help to reduce HIV incidence, but there is a dearth of research that can inform the potential scale-up of PrEP in India. In partnership with Ashodaya Samithi, a local sex worker collective, we conducted a feasibility study to assess acceptance of a planned PrEP demonstration project, willingness to use PrEP, and recommendations for project roll-out among FSWs in southern Karnataka. Methods From January–April 2015, 6 focus group discussions, 47 in-depth interviews, and 427 interviewer-administered questionnaires were completed by female sex workers. All participants were 18 years of age or older and practiced sex work. Qualitative data were coded for key themes and emergent categories. Univariate descriptive analysis was employed to summarise the quantitative data. Results Qualitative. PrEP was described as an exciting new prevention technology that places control in the hands of FSWs and provides a “double safety” in combination with condom use. Participants expressed agreement that women who may experience more HIV risk in their occupational environments should be prioritized for enrollment into a demonstration project. Quantitative. 406 participants (95%) expressed interest in PrEP. Participants prioritized the inclusion of FSWs under the age of 25 (79%), those who do not use condoms when clients offer more money (58%), who do not consistently use condoms with regular partners (57%), who drink alcohol regularly (49%), and who do not use condoms consistently with clients (48%). Discussion This feasibility study indicated strong interest in PrEP and a desire to move forward with the demonstration project. Participants expressed their responses in terms of public health discourses surrounding risk, pointing to the importance of situating PrEP scale up within the trusted spaces of

    The phosphatidylinositol 3-kinase (PI3K)/protein kinase B (PKB/AKT)/mammalian target of rapamycin (mTOR) pathway conveys signals from receptor tyrosine kinases (RTKs) to regulate cell metabolism, proliferation, survival, and motility. Previously we found that prolylcarboxypeptidase (PRCP) regulate proliferation and survival in breast cancer cells. In this study, we found that PRCP and the related family member prolylendopeptidase (PREP) are essential for proliferation and survival of pancreatic cancer cells. Depletion/inhibition of PRCP and PREP-induced serine phosphorylation and degradation of IRS-1, leading to inactivation of the cellular PI3K and AKT. Notably, depletion/inhibition of PRCP/PREP destabilized IRS-1 in the cells treated with rapamycin, blocking the feedback activation PI3K/AKT. Consequently, inhibition of PRCP/PREP enhanced rapamycin-induced cytotoxicity. Thus, we have identified PRCP and PREP as a stabilizer of IRS-1 which is critical for PI3K/AKT/mTOR signaling in pancreatic cancer cells. PMID:24936056

    The Stress of Immigration Survey (SOIS) is a screening tool used to assess immigration-related stress. The mixed methods approach included concept development, pretesting, field testing, and psychometric evaluation in a sample of 131 low-income women of Mexican descent. The 21-item SOIS screens for stress related to language, immigrant status, work issues, yearning for family and home country, and cultural dissonance. Mean scores ranged from 3.6 to 4.4 (a scale of 1-5, higher is more stress). Cronbach α values were more than 0.80 for all subscales. The SOIS may be a useful screening tool for detecting high levels of immigration-related stress in low-income Mexican immigrant women.

    2014-01-01

    With the development of cryptography, the attribute-based encryption (ABE) draws widespread attention of the researchers in recent years. The ABE scheme, which belongs to the public key encryption mechanism, takes attributes as public key and associates them with the ciphertext or the user's secret key. It is an efficient way to solve open problems in access control scenarios, for example, how to provide data confidentiality and expressive access control at the same time. In this paper, we survey the basic ABE scheme and its two variants: the key-policy ABE (KP-ABE) scheme and the ciphertext-policy ABE (CP-ABE) scheme. We also pay attention to other researches relating to the ABE schemes, including multiauthority, user/attribute revocation, accountability, and proxy reencryption, with an extensive comparison of their functionality and performance. Finally, possible future works and some conclusions are pointed out. PMID:25101313

Messengers for Health, a project based on the Apsáalooke (Crow Indian) reservation, utilizes a lay health advisor approach to decrease cervical cancer screening barriers, increase knowledge regarding screening and prevention, and increase the proportion of women receiving Pap tests among Apsáalooke women aged 18 and older. This project utilizes a community-based participatory research model, which emphasizes community member involvement in all phases of the project. The initial phase of this project was the development and implementation of a culturally sensitive survey used to guide the program and benefit the community. The process and preliminary results are presented.

    Conducting clinical trials in neonates is challenging, and knowledge gaps in neonatal clinical pharmacology exist. We surveyed the US Food and Drug Administration databases and identified 43 drugs studied in neonates or referring to neonates between 1998 and 2014. Twenty drugs were approved in neonates. For 10 drugs, approval was based on efficacy data in neonates, supplemented by pharmacokinetic data for four drugs. Approval for neonates was based on full extrapolation from older patients for six drugs, and partial extrapolation was the basis of approval for four drugs. Dosing recommendations differed from older patients for most drugs, and used body-size based adjustment in neonates. Trial failures were associated with various factors including inappropriate dose selection. Successful drug development in neonates could be facilitated by an improved understanding of the natural history and pathophysiology of neonatal diseases and identification and validation of clinically relevant biomarkers.

    Neurotransmitters are not only involved in brain function but are also important signaling molecules for many diverse cell types. Neurotransmitters are widely conserved, from evolutionarily ancient organisms lacking nervous systems through man. Here, we report results from a loss- and gain-of-function survey, using pharmacologic modulators of several neurotransmitter pathways to examine possible roles in normal embryogenesis. Applying reagents targeting the glutamatergic, adrenergic, and dopaminergic pathways to embryos of Xenopus laevis from gastrulation to organogenesis stages, we observed and quantified numerous malformations including craniofacial defects, hyperpigmentation, muscle mispatterning, and miscoiling of the gut. These data implicate several key neurotransmitters in new embryonic patterning roles, reveal novel earlier stages for processes involved in eye development, suggest new targets for subsequent molecular-genetic investigation, and highlight the necessity for in-depth toxicology studies of psychoactive compounds to which human embryos might be exposed during pregnancy.

    Sesame (Sesamum indicum), an important oil crop, is widely grown in tropical and subtropical regions. It provides part of the daily edible oil allowance for almost half of the world's population. A limited number of co-dominant markers has been developed and applied in sesame genetic diversity and germplasm identity studies. Here we report for the first time a whole genome survey used to develop simple sequence repeat (SSR) markers and to detect the genetic diversity of sesame germplasm. From the initial assembled sesame genome, 23,438 SSRs (≥5 repeats) were identified. The most common repeat motif was dinucleotide with a frequency of 84.24%, followed by 13.53% trinucleotide, 1.65% tetranucleotide, 0.3% pentanucleotide and 0.28% hexanucleotide motifs. From 1500 designed and synthesised primer pairs, 218 polymorphic SSRs were developed and used to screen 31 sesame accessions that from 12 countries. STRUCTURE and phylogenetic analyses indicated that all sesame accessions could be divided into two groups: one mainly from China and another from other countries. Cluster analysis classified Chinese major sesame varieties into three groups. These novel SSR markers are a useful tool for genetic linkage map construction, genetic diversity detection, and marker-assisted selective sesame breeding.

    It has been shown that sublingual nitroglycerin (NTG) improves image quality of coronary lumen magnetic resonance angiography. Our aim was to investigate the influence of NTG on coronary lumen and vessel wall image quality using a combined, single sequence approach (i-T2prep), which is able to image both within the known time frame of action of NTG. Ten healthy volunteers underwent right coronary artery lumen and vessel wall imaging using the i-T2prep sequence before and after administration of NTG. Image quality was assessed qualitatively and quantitatively. Diameter, length and wall thickness were also measured using dedicated semi-automatic software. NTG induced coronary vasodilatation (lumen diameter increased from 2.16 ± 0.32 to 2.52 ± 0.59 mm; p = 0.036). As a result, visualized lumen length (9.8 ± 2.6 to 11.4 ± 3.3 cm; p = 0.025) and qualitative lumen image quality (median 3 (interquartile range 2-3.25) vs. median 3 (interquartile range 3-4); p = 0.046) both improved. Vessel wall imaging also demonstrated a significant improvement in vessel wall sharpness after NTG (24.8 vs. 27.3 %; p = 0.036). This study demonstrates the benefits of NTG for coronary lumen and vessel wall imaging using a combined sequence, i-T2prep. The methodology described here has great potential for future pathophysiological studies.

    Co-factor homeodomain proteins such as Drosophila Homothorax (Hth) and Extradenticle (Exd) and their respective vertebrate homologs, the Meis/Prep and Pbx proteins, can increase the DNA-binding specificity of Hox protein transcription factors and appear to be required for many of their developmental functions. We show that the unc-62 gene encodes the C. elegans ortholog of Hth, and that maternal-effect unc-62 mutations can cause severe posterior disorganization during embryogenesis (Nob phenotype), superficially similar to that seen in embryos lacking function of either the two posterior-group Hox genes nob-1 and php-3 or the caudal homolog pal-1. Other zygotically acting unc-62 alleles cause earlier embryonic arrest or incompletely penetrant larval lethality with variable morphogenetic defects among the survivors, suggesting that unc-62 functions are required at several stages of development. The differential accumulation of four unc-62 transcripts is consistent with multiple functions. The C. elegans exd homologs ceh-20 and ceh-40 interact genetically with unc-62 and may have overlapping roles in embryogenesis: neither CEH-20 nor CEH-40 appears to be required when the other is present, but loss of both functions causes incompletely penetrant embryonic lethality in the presence of unc-62(+) and complete embryonic lethality in the presence of an unc-62 hypomorphic allele.

    Objective To classify individuals with diabetes mellitus (DM) into DM subtypes using population-based studies. Design Population-based survey Setting Individuals participated in 2003–2004, 2005–2006, or 2009–2010 the National Health and Nutrition Examination Survey (NHANES), and 2010 Coronary Artery Risk Development in Young Adults (CARDIA) survey (research materials obtained from the National Heart, Lung, and Blood Institute Biologic Specimen and Data Repository Information Coordinating Center) Participants 3084, 3040 and 3318 US adults from the 2003–2004, 2005–2006 and 2009–2010 NHANES samples respectively, and 5,115 US adults in the CARDIA cohort Primary outcome measures We proposed the Diabetes Typology Model (DTM) through the use of six composite measures based on the Homeostatic Model Assessment (HOMA-IR, HOMA-%β, high HOMA-%S), insulin and glucose levels, and body mass index and conducted latent class analyses to empirically classify individuals into different classes. Results Three empirical latent classes consistently emerged across studies (entropy = 0.81–0.998). These three classes were likely Type 1 DM, likely Type 2 DM, and atypical DM. The classification has high sensitivity (75.5%), specificity (83.3%), and positive predictive value (97.4%) when validated against C-peptide level. Correlates of Type 2 DM were significantly associated with model-identified Type 2 DM. Compared to regression analysis on known correlates of Type 2 DM using all diabetes cases as outcomes, using DTM to remove likely Type 1 DM and atypical DM cases results in a 2.5–5.3% r-square improvement in the regression analysis, as well as model fits as indicated by significant improvement in -2 log likelihood (p<0.01). Lastly, model-defined likely Type 2 DM was significantly associated with known correlates of Type 2 DM (e.g., age, waist circumference), which provide additional validation of the DTM-defined classes. Conclusions Our Diabetes Typology Model reflects a

    2011-01-01

    Background Scientists from less-developed countries (LDC) perceive that it is difficult to publish in international journals from their countries. This online survey was conducted with the primary aim of determining the opinion of corresponding authors of published papers in international Pharmacology journals regarding the difficulties in publications and their possible solutions. Methods The titles of all Pharmacology journals were retrieved from Pubmed. 131 journals were included in study. The latest issue of all journals was reviewed thoroughly. An online survey was conducted from the corresponding authors of the published papers who belonged to LDC. Results 584 out 1919 papers (30.4%) originated from the LDC. 332 responses (response rate; 64.5%) were received from the authors. Approximately 50% the papers from LDC were published in journals with impact factor of less than 2. A weak negative correlation (r = -0.236) was observed between journal impact factor and the percentage of publications emanating from LDC. A significant majority of the corresponding authors (n = 254; 76.5%) perceived that it is difficult to publish in good quality journals from their countries. According to their opinion, biased attitude of editors and reviewers (64.8%) is the most important reason followed by the poor writing skills of the scientists from LDC (52.8%). The authors thought that well-written manuscript (76.1%), improvement in the quality of research (69.9%) and multidisciplinary research (42.9%) are important determinants that may improve the chances of publications. Conclusions The LDC are underrepresented in publications in Pharmacology journals. The corresponding authors of the published articles think that biased attitude of the editors as well as the reviewers of international journals and the poor writing skills of scientists are the major factors underlying the non-acceptance of their results. They also think that the improvement in the writing skills and quality of

    Objective Despite the tremendous disability and mortality caused by traumatic injuries worldwide, there is a relative dearth of information on the burden of injuries in developing countries. In an effort to document the surgical burden of disease in Sierra Leone, a nationwide survey was conducted utilizing the Surgeons OverSeas Assessment of Surgical Need (SOSAS) tool. Here, we report the injury data from this study with the aim to (1) provide an estimate of injury prevalence, (2) determine the mechanisms of injury, and (3) evaluate the degree of injury related deaths. Methods A population-based household survey was conducted in Sierra Leone in 2012. Participants were selected using a two-stage random sampling method, which generated a target population of 3750 participants across the 14 districts of Sierra Leone. Frequency distributions of mechanisms of injury based on age, sex, and urban versus rural residence were computed, and bivariate logistic regression models used to determine associations between sociodemographic factors and injury patterns. Results Data was analyzed from 1,843 households and 3,645 respondents, representing a response rate of 98.3%. Four hundred and fifty-two respondents (12.4%) reported at least one traumatic injury in the preceding year. Falls were the most common cause of non-fatal injuries, accounting for over 40% of injuries. The extremities were most commonly injured (55% of injuries) regardless of age or sex. Although motor vehicle related injuries were the 4th most common cause of injury overall, they were the leading cause of injury related deaths, accounting for almost 6% of fatal injuries. Conclusion This study provides baseline data on the burden of traumatic injuries in one of the world's poorest nations. In addition to injury prevention measures, immediate strategies to address current healthcare deficits are urgently needed in these resource poor areas. This report is an Original Article with Level I evidence. PMID:23325317

  17. Development and Evaluation of a Uav Based Mapping System for Remote Sensing and Surveying Applications

    In recent years, unmanned aerial vehicles (UAVs) have increasingly been used in various application areas, such as in the remote sensing or surveying. For these applications the UAV has to be equipped with a mapping sensor, which is mostly a camera. Furthermore, a georeferencing of the UAV platform and/or the acquired mapping data is required. The most efficient way to realize this georeferencing is the direct georeferencing, which is based on an onboard multi-sensor system. In recent decades, direct georeferencing systems have been researched and used extensively in airborne, ship and land vehicle applications. However, these systems cannot easily be adapted to UAV platforms, which is mainly due to weight and size limitations. In this paper a direct georeferencing system for micro- and mini-sized UAVs is presented, which consists of a dual-frequency geodetic grade OEM GPS board, a low-cost single-frequency GPS chip, a tactical grade IMU and a magnetometer. To allow for cm-level position and sub-degree attitude accuracies, RTK GPS (real-time kinematic) and GPS attitude (GPS compass) determination algorithms are running on this system, as well as a GPS/IMU integration. Beside the direct georeferencing, also the precise time synchronization of the camera, which acts as the main sensor for mobile mapping applications, and the calibration of the lever arm between the camera reference point and the direct georeferencing reference point are explained in this paper. Especially the high accurate time synchronization of the camera is very important, to still allow for high surveying accuracies, when the images are taken during the motion of the UAV. Results of flight tests demonstrate that the developed system, the camera synchronization and the lever arm calibration make directly georeferenced UAV based single point measurements possible, which have cm-level accuracies on the ground.

    This study describes infant feeding practices in developing countries, specifically complementary liquids and foods in the first year of life. Data were compiled from Demographic and Health Surveys conducted from 1999 to 2003. We analyzed data from those countries with available data, including results for child-level 24-h and 7-d food and fluid intakes. We used datasets from 20 countries with information on >35,000 infants categorized by age: 0-6 and 6-12 mo. For analysis, we grouped data for fluids other than breast milk as water, other milk (e.g., tinned, powdered, animal), infant formula, and other liquids (e.g., fruit juice, herbal tea, sugar water). All specific solid foods were grouped as any solid foods. We present data on breast-feeding and maternal-reported fluid and solid intake by infants in a 24-h period, for individual countries, and in a pooled analysis. Pooled data show that 96.6% of 0- to 6- and 87.9% of 6- to 12-mo-old infants were currently breast-fed. Reported feeding of other fluids was lower among 0- to 6-mo-olds than 6- to 12-mo-olds: water (45.9 vs. 87.4%), other milk products (11.9 vs. 29.6%), infant formula (9.0 vs. 15.1%), and other liquids (15.1 vs. 41.0%). Pooled analysis showed that 21.9% of mothers reported feeding 0- to 6-mo-old infants some type of solid food, and 80.1% of mothers reported feeding solids to 6- to 12-mo-olds. These survey data show that other milks, other liquids, and solid foods are each much more commonly fed throughout infancy than commercial infant formulas in the countries studied.

    Background: Intimate partner violence (IPV) is associated with higher HIV incidence, reduced condom use, and poor adherence to antiretroviral therapy and other medications. IPV may also affect adherence to pre-exposure prophylaxis (PrEP). Methods: We analyzed data from 1785 HIV-uninfected women enrolled in a clinical trial of PrEP among African HIV serodiscordant couples. Experience of verbal, physical, or economic IPV was assessed at monthly visits by face-to-face interviews. Low PrEP adherence was defined as clinic-based pill count coverage <80% or plasma tenofovir levels <40 ng/mL. The association between IPV and low adherence was analyzed using generalized estimating equations, adjusting for potential confounders. In-depth interview transcripts were examined to explain how IPV could impact adherence. Results: Sixteen percent of women reported IPV during a median of 34.8 months of follow-up (interquartile range 27.0–35.0). Overall, 7% of visits had pill count coverage <80%, and 32% had plasma tenofovir <40 ng/mL. Women reporting IPV in the past 3 months had increased risk of low adherence by pill count (adjusted risk ratio 1.49, 95% confidence interval: 1.17 to 1.89) and by plasma tenofovir (adjusted risk ratio 1.51, 95% confidence interval: 1.06 to 2.15). Verbal, economic, and physical IPV were all associated with low adherence. However, the impact of IPV diminished and was not statistically significant 3 months after the reported exposure. In qualitative interviews, women identified several ways in which IPV affected adherence, including stress and forgetting, leaving home without pills, and partners throwing pills away. Conclusions: Women who reported recent IPV in the Partners PrEP Study were at increased risk of low PrEP adherence. Strategies to mitigate PrEP nonadherence in the context of IPV should be evaluated.

    Growing interest in the environmental aspects of migration is not matched by research on their interrelationships, due partly to the lack of adequate data sets on the two together. Focusing on the microlevel, we describe the data required to effectively investigate these interrelationships. Data sources are discussed, be collected, focusing on household surveys and remote sensing. The main section of the paper describes three alternative approaches to data collection: (a) using existing population and environmental data from different sources, illustrated by Burkina Faso; (b) adding questions to a survey developed for another purpose, illustrated for Guatemala using a DHS survey; and (c) designing a new survey specifically to collect both migration and environmental data to investigate interrelationships, illustrated by Ecuador. Methods used and summary findings are described, followed by a discussion of their advantages and limitations. We conclude with recommendations as to effective use of each approach as research on migration–environment linkages moves forward. PMID:24701002

    Stingless bees are an important asset to assure plant biodiversity in many natural ecosystems, and fulfill the growing agricultural demand for pollination. However, across developing countries stingless beekeeping remains an essentially informal activity, technical knowledge is scarce, and management practices lack standardization. Here we profited from the large diversity of stingless beekeepers found in Brazil to assess the impact of particular management practices on productivity and economic revenues from the commercialization of stingless bee products. Our study represents the first large-scale effort aiming at optimizing stingless beekeeping for honey/colony production based on quantitative data. Survey data from 251 beekeepers scattered across 20 Brazilian States revealed the influence of specific management practices and other confounding factors over productivity and income indicators. Specifically, our results highlight the importance of teaching beekeepers how to inspect and feed their colonies, how to multiply them and keep track of genetic lineages, how to harvest and preserve the honey, how to use vinegar traps to control infestation by parasitic flies, and how to add value by labeling honey containers. Furthermore, beekeeping experience and the network of known beekeepers were found to be key factors influencing productivity and income. Our work provides clear guidelines to optimize stingless beekeeping and help transform the activity into a powerful tool for sustainable development.

    2014-01-01

    The mycotoxigenic fungal species Fusarium graminearum is able to attack several important cereal crops, such as wheat and barley. By causing Fusarium Head Blight (FHB) disease, F. graminearum induces yield and quality losses and poses a public health concern due to in planta mycotoxin production. The molecular and physiological plant responses to FHB, and the cellular biochemical pathways used by F. graminearum to complete its infectious process remain still unknown. In this study, a proteomics approach, combining 2D-gel approach and mass spectrometry, has been used to determine the specific protein patterns associated with the development of the fungal infection during grain growth on susceptible wheat. Our results reveal that F. graminearum infection does not deeply alter the grain proteome and does not significantly disturb the first steps of grain ontogeny but impacts molecular changes during the grain filling stage (impact on starch synthesis and storage proteins). The differentially regulated proteins identified were mainly involved in stress and defence mechanisms, primary metabolism, and main cellular processes such as signalling and transport. Our survey suggests that F. graminearum could take advantage of putative susceptibility factors closely related to grain development processes and thus provide new insights into key molecular events controlling the susceptible response to FHB in wheat grains.

    Valent, Philip J.; Riggins, Michael

    1989-04-01

    An overview is given of current and developing technologies and techniques for performing geotechnical investigations for siting and designing Cold Water Pipes (CWP) for shelf-resting Ocean Thermal Energy Conversion (OTEC) power plants. The geotechnical in situ tools used to measure the required parameters and the equipment/systems used to deploy these tools are identified. The capabilities of these geotechnical tools and deployment systems are compared to the data requirements for the CWP foundation/anchor design, and shortfalls are identified. For the last phase of geotechnical data gathering for design, a drillship will be required to perform soil boring work, to obtain required high quality sediment samples for laboratory dynamic testing, and to perform deep penetration in situ tests. To remedy shortfalls and to reduce the future OTEC CWP geotechnical survey costs, it is recommended that a seafloor resting machine be developed to advance the friction cone penetrometer, and also probably a pressuremeter, to provide geotechnical parameters to shallow subseafloor penetrations on slopes of 35 deg and in water depths to 1300 m.

    Energy demand in Malaysia is increasing over seven per cent a year, while forty per cent of the energy is supplied from conventional fossil fuel. However, a number of social barriers have mired the social acceptance of renewable energy among the users. This study investigates the current status of renewable energy, problems and future outlook of renewable energy in Malaysia. A total of 200 respondents were surveyed from Klang Valley in Malaysia. Majority of the respondents use energy to generate electricity. Although some respondents reported using solar energy, there is lack of retail availability for solar energy. The findings show that limited information on renewable energy technologies, lack of awareness, and limited private sector engagement emerged as major barriers to sustainable renewable energy development. In addition, the respondents suggest for increasing policy support from the government to make information more accessible to mass users, provide economic incentives to investors and users, and promote small-community based renewable energy projects. The study suggests that the government begin small scale projects to build awareness on renewable energy, while academically, higher learning institutions include renewable energy syllabus in their academic curriculum. The study concluded that to have sustainable renewable energy development, government's initiative, private sector engagement and users awareness must be given priority.

    The objective of this work was to evaluate the precision and accuracy of the milk yield predictions made by the PREP10 model in comparison to those from the National Research Council (NRC) Nutrient Requirements of Dairy Cattle. The PREP10 model is a ration-balancing system that allows protein use efficiency to vary with production level. The model also has advanced AA supply and requirement calculations that enable estimation of AA-allowable milk (MilkAA) based on 10 essential AA. A literature data set of 374 treatment means was collected and used to quantitatively evaluate the estimates of protein-allowable milk (MilkMP) and energy-allowable milk yields from the NRC and PREP10 models. The PREP10 MilkAA prediction was also evaluated, as were both models' estimates of milk based on the most-limiting nutrient or the mean of the estimated milk yields. For most milk estimates compared, the PREP10 model had reduced root mean squared prediction error (RMSPE), improved concordance correlation coefficient, and reduced mean and slope bias in comparison to the NRC model. In particular, utilizing the variable protein use efficiency for milk production notably improved the estimate of MilkMP when compared with NRC. The PREP10 MilkMP estimate had an RMSPE of 18.2% (NRC = 25.7%), concordance correlation coefficient of 0.82% (NRC = 0.64), slope bias of -0.14 kg/kg of predicted milk (NRC = -0.34 kg/kg), and mean bias of -0.63 kg (NRC = -2.85 kg). The PREP10 estimate of MilkAA had slightly elevated RMSPE and mean and slope bias when compared with MilkMP. The PREP10 estimate of MilkAA was not advantageous when compared with MilkMP, likely because AA use efficiency for milk was constant whereas MP use was variable. Future work evaluating variable AA use efficiencies for milk production is likely to improve accuracy and precision of models of allowable milk.

    Objective: The efficacy of pre-exposure prophylaxis (PrEP) in HIV will diminish with poor adherence; pharmacologic measures of drug exposure have proven critical to PrEP trial interpretation. We assessed drug exposure in hair against other pharmacologic and more routinely used measures to assess pill-taking. Design: Participants were randomized to placebo, daily PrEP, or intermittent PrEP to evaluate safety and tolerability of daily versus intermittent tenofovir/emtricitabine (TFV/FTC) in 2 phase II PrEP clinical trials conducted in Africa. Different measures of drug exposure, including self-report, medication event monitoring system (MEMS)-caps openings, and TFV/FTC levels in hair and other biomatrices were compared. Methods: At weeks 8 and 16, self-reported pill-taking, MEMS-caps openings, and TFV/FTC levels in hair, plasma, and peripheral blood mononuclear cells (PBMCs) were measured. Regression models evaluated predictors of TFV/FTC concentrations in the 3 biomatrices; correlation coefficients between pharmacologic and nonpharmacologic measures were calculated. Both trials were registered on ClinicalTrials.gov (NCT00931346/NCT00971230). Results: Hair collection was highly feasible and acceptable (100% in week 8; 96% in week 16). In multivariate analysis, strong associations were seen between pharmacologic measures and MEMS-caps openings (all P < 0.001); self-report was only weakly associated with pharmacologic measures. TFV/FTC hair concentrations were significantly correlated with levels in plasma and PBMCs (correlation coefficients, 0.41–0.86, all P < 0.001). Conclusions: Measuring TFV/FTC exposure in small hair samples in African PrEP trials was feasible and acceptable. Hair levels correlated strongly with PBMC, plasma concentrations, and MEMS-caps openings. As in other PrEP trials, self-report was the weakest measure of exposure. Further study of hair TFV/FTC levels in PrEP trials and demonstration projects to assess adherence/exposure is warranted. PMID

    Fertility nursing and its role extension has increasingly been referred to as 'specialist' or 'advanced nursing practice'. Nevertheless, Government initiatives have prompted a review of 'Advanced Nursing Practice' and the Nursing & Midwifery Council (NMC) has taken steps to address the disparity of roles, job titles, training and competence of nurse practitioners, concluding that advanced nursing practice should be subject to revalidation in the same way as professional registration. Fertility nurses form an integral part of the multidisciplinary team. Yet no formal or nationally recognised framework or training pathway exists. In this paper, we present the findings of a recent online survey of training and educational needs of fertility nurses; its aim being to work toward developing a national training pathway. Our findings identify the relationship between fertility nurse competencies, advanced nursing practice and medical sub-specialist training, at the same time, highlighting the difference in accessibility, funding and levels of training, as well as assessment and expertise within clinical practice. We conclude that it is essential to protect role extension through regonised Higher Educational Institution (HEI) accreditation, by appropriate, role-focussed training. Notwithstanding a national review, the diverse list of job titles also needs to be addressed adequately to encompass and respect role extension.

    The U.S. Geological Survey has developed new standard rating tables for use with Price type AA and pygmy current meters, which are employed to measure streamflow velocity. Current-meter calibration data, consisting of the rates of rotation of meters at several different constant water velocities, have shown that the original rating tables are no longer representative of the average responsiveness of newly purchased meters or meters in the field. The new rating tables are based on linear regression equations that are weighted to reflect the population mix of current meters in the field and weighted inversely to the variability of the data at each calibration velocity. For calibration velocities of 0.3 m/s and faster, at which most streamflow measurements are made, the new AA-rating predicts the true velocities within 1.5% and the new pygmy-meter rating within 2.0% for more than 95% of the meters. At calibration velocities, the new AA-meter rating is up to 1.4% different from the original rating, and the new pygmy-meter rating is up to 1.6% different.

    Psychological factors are thought to play a part in the aetiology of chronic widespread pain. We investigated the relationship between intelligence in childhood and risk of chronic widespread pain in adulthood in 6902 men and women from the National Child Development Survey (1958 British Birth Cohort). Participants took a test of general cognitive ability at age 11 years; and chronic widespread pain, defined according to the American College of Rheumatology criteria, was assessed at age 45 years. Risk ratios (RRs) and 95% confidence intervals (CIs) were estimated using log-binomial regression, adjusting for sex and potential confounding or mediating factors. Risk of chronic widespread pain, defined according to the American College of Rheumatology criteria, rose in a stepwise fashion as intelligence fell (P for linear trend <0.0001). In sex-adjusted analyses, for an SD lower intelligence quotient, the RR of chronic widespread pain was 1.26 (95% CI 1.17-1.35). In multivariate backwards stepwise regression, lower childhood intelligence remained as an independent predictor of chronic widespread pain (RR 1.10; 95% CI 1.01-1.19), along with social class, educational attainment, body mass index, smoking status, and psychological distress. Part of the effect of lower childhood intelligence on risk of chronic widespread pain in midlife was significantly mediated through greater body mass index and more disadvantaged socioeconomic position. Men and women with higher intelligence in childhood are less likely as adults to report chronic widespread pain.

    About one in five Americans spends a considerable number of hours in school each week, and thus, is exposed to a variety of environmental agents. Community health nursing professionals require resources and specific training to acquire the environmental knowledge needed to raise personal and community awareness as an enhancement of their practice. Given limited resources for schools and local public health education initiatives, identifying and prioritizing environmental concerns comes before actions to prevent or reduce exposures. With the rise in prevalence of childhood asthma, of special concern are those agents within the school environment that may serve as asthma triggers. This pilot project, within a larger study in a large school district in metropolitan Atlanta, Georgia, developed and piloted an environmental health priorities survey with school nurses and other school staff about indoor and outdoor microenvironments relevant to school-aged children. Findings indicate that participants (N = 34) could prioritize environmental issues to inform future intervention activities (such as continuing education training), and distinguish predominantly indoor from typical outdoor exposure agents and their major sources.

    Continuing professional development (CPD) and continuing professional education (CPE) are seen as being necessary for medical physicists to ensure that they are up-to-date with current clinical practice. CPD is more than just continuing professional education, but can include research publication, working group contribution, thesis examination and many other activities. A systematic way of assessing and recording such activities that a medical physicist undertakes is used in a number of countries. This can be used for certification and licensing renewal purposes. Such systems are used in 27 countries, but they should be implemented in all countries where clinical medical physicists are employed. A survey of the CPD systems that are currently operated around the world is presented. In general they are quite similar although there are a few countries that have CPD systems that differ significantly from the others in many respects. Generally they ensure that medical physicists are kept up-to-date, although there are some that clearly will fail to achieve that. An analysis of what is required to construct a useful medical physics CPD system is made. Finally, the need for medical physicist professional organizations to cooperate and share in the production and distribution of CPD and CPE materials is emphasized.

    A mobile mass spectrometer to measure He concentrations has been developed by the U.S. Geological Survey. This instrument has been tested in areas of known uranium deposits, and He anomalies have been found in both soil gas and water. A gas sample is collected in a hypodermic syringe, injected into the spectrometer, and analyzed for He. Over 100 analyses a day can be performed with a sensitivity of 10 parts per billion (ppb). One detailed study conducted in Weld County, Colorado, shows that values for He in soil gas can be contoured to outline an anomalous area and that the anomaly is displaced from the deposit in the direction of groundwater flow. Other studies include the Schwartzwalder uranium mine, Jefferson County, Colorado, where He anomalies may be related to geologic structure; near Ambrosia Lake, New Mexico, where the location of He anomalies are related to groundwater movement; and tests for diurnal effects showing only slight variations probably related to soil-moisture content. ?? 1979.

  19. Development and testing of the Clinical Post-Conference Learning Environment Survey.

    1998-01-01

    Clinical postconference is an integral component of the required laboratory hours in undergraduate baccalaureate nursing education. Empirical evidence supporting the educational benefits of this activity are nearly nonexistent. This article describes the development and psychometric testing of a self-report instrument designed to measure clinical postconference learning environments as perceived by undergraduate nursing students and faculty. The Clinical Post-Conference Learning Environment Survey (CPCLES) consists of 54 items and has been tested with more than 500 participants in three schools of nursing in the Midwest. Based on theoretical support and comprehensive review of the literature, six components of the learning environment are measured in two forms of the instrument; an actual scale and an importance scale. Content validity, internal consistency, and test-retest reliability are discussed. Using the CPCLES, perceptions of undergraduate nursing students and faculty were measured. Significant differences between the actual components of the learning environment and the correlated ratings of the importance of these components were found. Faculty perceived a significantly greater amount of teacher support, task orientation, and innovation in the postconference learning environment than did undergraduate students. No differences were noted between faculty and students regarding the importance of the learning environment components. This study presents findings with the use of the first instrument developed to measure clinical postconference learning environments. The congruence and discrepancy among and between learning groups' perceptions carry implications for educational practices in this setting. Subseqent investigations using this tool may be able to link the perceived learning environment to valued cognitive, affective, and behavioral learning outcomes.

  20. Misconduct in research: a descriptive survey of attitudes, perceptions and associated factors in a developing country

    2014-01-01

    Background Misconduct in research tarnishes the reputation, credibility and integrity of research institutions. Studies on research or scientific misconduct are still novel in developing countries. In this study, we report on the attitudes, perceptions and factors related to the work environment thought to be associated with research misconduct in a group of researchers in Nigeria - a developing country. Method A survey of researchers attending a scientific conference was done using an adapted Scientific Misconduct Questionnaire-Revised (SMQ-R). Initial descriptive analysis of individual items using frequencies and proportions for all quantitative data was performed. Thereafter, Likert scale responses were transformed into dichotomous responses. Fisher exact test was performed for associations as appropriate. A two-tailed p-value of less than 0.05 was accepted as significant. Result Half of the respondents (50.4%) were aware of a colleague who had committed misconduct, defined as “non-adherence to rules, regulations, guidelines, and commonly accepted professional codes or norms”. Over 88% of the researchers were concerned about the perceived amount of misconduct prevalent in their institution and 96.2% believed that one or more forms of scientific misconduct had occurred in their workplace. More than half (52.7%) rated the severity of penalties for scientific misconduct in their work environment as low. Furthermore¸ the majority (56.1%) were of the view that the chance of getting caught for scientific misconduct in their work environment was low. Conclusion Researchers in Nigeria perceive that scientific misconduct is commonplace in their institutions, but are however worried about the negative effects of scientific misconduct on the credibility of scientific research. We recommend that researchers be empowered with the knowledge and virtues necessary for self-regulation that advance research integrity. Research institutions should however also step into their
