Full Text Available Gay, bisexual, and other men who have sex with men (GBM are disproportionately affected by the HIV epidemic. Despite the promise of pre-exposure prophylaxis (PrEP in reducing HIV transmission risk, barriers for uptake and persistence exist. We sought to identify whether GBM in a nationwide cohort who have not yet initiated PrEP (n = 906 would prefer to get PrEP-related care from a primary care provider (PCP compared to a specialist clinic or provider. We then sought to identify their level of interest and factors associated with preference for using home-based PrEP services (i.e., HB-PrEP, defined to participants as conducting HIV/STI self-testing from home with PrEP prescription mailing after an initial in-person clinic visit. We examined the associations of demographics, sexual HIV transmission risk, concern about frequent medical checkups associated with PrEP, health care access, and PrEP intentions with preferences for healthcare provider type and HB-PrEP. Concern about frequent medical checkups were associated with preferring a PCP for PrEP-related care, but men who perceived a barrier to bringing up the topic of PrEP with a doctor preferred a specialist clinic or provider more than a PCP. HB-PrEP was more appealing for younger men and those engaged in sexual HIV transmission risk, suggesting HB-PrEP could help reach GBM most vulnerable to HIV and in need of PrEP. HB-PrEP expansion has potential to increase PrEP uptake and persistence among GBM, particularly for men with barriers to clinic-based care and higher intentions to initiate PrEP. Clinical guidelines regarding HB-PrEP are needed to expand its use.

The aim of this study was to determine the intention to use pre-exposure prophylaxis (PrEP) when available and to identify predictors of the intention to use PrEP among men who have sex with men (MSM) living in Switzerland. The theoretical model drew on the Unified Theory of Acceptance and Use of Technology and considered additional variables related specifically to PrEP, HIV protection and the resources of MSM. For data collection, we used an anonymous, standardized self-administered online questionnaire. In 2015, we gathered a convenience sample of 556 HIV-negative MSM living in Switzerland. We analyzed the data using descriptive and bivariate statistics and used structural equation modeling to test the hypothesized model. Predictors of respondents' moderate intention to use PrEP were performance expectancy, effort expectancy, perceived social influence, concerns about using PrEP, attitudes toward condom use, negative experiences of condom use and age. These variables were predicted by HIV protection-related aspects and resources. The findings provide insights into the complex dynamic underlying the intention to use PrEP.

Social biases among healthcare providers could limit PrEP access. In this survey study of 115 US medical students, we examined associations between biases (racism and heterosexism) and PrEP clinical decision-making and explored prior PrEP education as a potential buffer. After viewing a vignette about a PrEP-seeking MSM patient, participants reported anticipated patient behavior (condomless sex, extra-relational sex, and adherence), intention to prescribe PrEP to the patient, biases, and background characteristics. Minimal evidence for racism affecting clinical decision-making emerged. In unadjusted analyses, heterosexism indirectly affected prescribing intention via all anticipated behaviors, tested as parallel mediators. Participants expressing greater heterosexism more strongly anticipated increased risk behavior and adherence problems, which were associated with lower prescribing intention. The indirect effect via condomless sex remained significant adjusting for background characteristics. Prior PrEP education did not buffer any indirect effects. Heterosexism may compromise PrEP provision to MSM and should be addressed in PrEP-related medical education.

The goal of this work is to better understand utilization and uptake of pre-exposure prophylaxis (PrEP) among young men who have sex with men (YMSM) and transgender women (TGW). We assessed trends and correlates of PrEP use and adherence across three time points of longitudinal data collection among 885 YMSM and TGW (aged 16-29) from the RADAR cohort in Chicago, 2015-2017. Past 6-month PrEP use increased across three visits: from 6.6 to 17.5%. In multivariable models, past 6-month PrEP use was significantly associated with participation in condomless sex, having more sexual partners, and older age. At least three-quarters of current PrEP users reported being ≥ 90% adherent to PrEP medication across all visits. Past 6-month PrEP use increased over time with those who participated in high-risk HIV behaviors also those most likely to have taken PrEP. As PrEP uptake continues to rise, more research will be needed to understand predictors of PrEP usage, as well as patterns of sexual behavior change following uptake.

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. 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.

HIV prevention method preferences were evaluated among 512 U.S. men who have sex with men (MSM; median age: 22 years). Approximately 90 % consistently preferred one option across pairwise comparisons of condoms, daily oral pre-exposure prophylaxis (PrEP), and long-acting PrEP delivered via either an injectable or one of two types of PrEP implants differing in visibility. Condoms were most frequently preferred (33.8 %), followed by non-visible implants (21.5 %), and oral PrEP (17.0 %); HIV risk was reported by more choosing implants. In a follow-up question comparing the four PrEP options only, daily oral pills and non-visible implants were most frequently preferred (35.5 and 34.3 %, respectively), followed by injections (25.2 %) and visible implants (4.3 %). An inductive, open-coding approach determined that convenience, duration of protection, and privacy were the most commonly cited reasons for a PrEP method choice, and associated with self-report of HIV risk. Tailoring PrEP product development to privacy and other concerns important to those at highest HIV risk may improve HIV prevention.

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. 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. 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. 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 needs of all MSM communities.

Full Text Available Considering the Preliminary Electoral Results Program (PERP as a database of the federal elections for president of the Mexican Republic, a methodology was developed in order to find representative samples of ballot boxes installed in the election’s day (quick count in different hours, due to its characteristics of gathering of information, the PREP in the first hours forms a non-representative sample of data. In a particular way, in the election of July 2, 2006, after 3 hours of opening the PREP, it was observed that the accuracy of the process of the quick counts was better than the one obtained by the IFE. Among other things, this allows to lower the cost, to increase the confidentiality of the ballot boxes used in the sampling and to distinguish in a precise moment the winning candidate long before PREP finishes.

Liver plays a key role in controlling body carbohydrate homeostasis by switching between accumulation and production of glucose and this way maintaining constant level of glucose in blood. Increased blood glucose level triggers release of insulin from pancreatic β-cells. Insulin represses hepatic glucose production and increases glucose accumulation. Insulin resistance is the main cause of type 2 diabetes and hyperglycemia. Currently thiazolidinediones (TZDs) targeting transcriptional factor PPARγ are used as insulin sensitizers for treating patients with type 2 diabetes. However, TZDs are reported to be associated with cardiovascular and liver problems and stimulate obesity. Thus, it is necessary to search new approaches to improve insulin sensitivity. A promising candidate is transcriptional factor Prep1, as it was shown earlier it could affect insulin sensitivity in variety of insulin-sensitive tissues. The aim of the present study was to evaluate a possible involvement of transcriptional factor Prep1 in control of hepatic glucose accumulation and production. We created mice with liver-specific Prep1 knockout and discovered that hepatocytes derived from these mice are much more sensitive to insulin, comparing to their WT littermates. Incubation of these cells with 100 nM insulin results in almost complete inhibition of gluconeogenesis, while in WT cells this repression is only partial. However, Prep1 doesn't affect gluconeogenesis in the absence of insulin. Also, we observed that nuclear content of gluconeogenic transcription factor FOXO1 was greatly reduced in Prep1 knockout hepatocytes. These findings suggest that Prep1 may control hepatic insulin sensitivity by targeting FOXO1 nuclear stability. - Highlights: • A novel model of liver-specific Prep1 knockout is established. • Ablation of Prep1 in hepatocytes increases insulin sensitivity. • Prep1 controls hepatic insulin sensitivity by regulating localization of FOXO1. • Prep1 regulates

It is increasingly clear that the HIV response will not be sustainable if the number of infections is not significantly reduced. For two decades, research has been ongoing to identify new behavioural and biomedical strategies to prevent HIV infection. In the past few years, the efficacy of several new strategies has been demonstrated, including oral pre-exposure prophylaxis (PrEP; i.e. daily use of tenofovir/emtricitabine). Because several social, political and logistic barriers remain, however, optimal PrEP implementation will require a better dissemination of new evidence in a number of areas and additional implementation research from various disciplinary perspectives (i.e. social science, policy and ethics; health systems; and economics, including cost-effectiveness studies). Discussion of new evidence on those topics, as well as case studies of potential PrEP implementation in diverse environments, can improve the understanding of the role that PrEP may play in addressing the global HIV/AIDS epidemic.In light of these needs, the Network for Multidisciplinary Studies in ARV-based HIV Prevention (NEMUS) and the World Health Organization (WHO) were honoured to co-organize a special issue of JIAS aimed at contributing to a scholarly discussion of current conditions surrounding PrEP implementation, potential impact and efficiency, social science concerns and the study of PrEP implementation in specific country cases. The papers included in this monograph identify and cover many of the main aspects of the complex yet promising discussions around PrEP implementation today. This is a collection of timely contributions from global leaders in HIV research and policy that addresses geographic diversity, uses a trans-disciplinary approach and covers a variety of the complex issues raised by PrEP. As this publication will become accessible to all, we hope that it will remain a valuable resource for policy makers, programme managers, researchers and activists around the

PrEP in Europe - expectations, opportunities and barriers.

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. 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. 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 blood-borne infections.

People at high risk for HIV acquisition should be offered pre-exposure prophylaxis (PrEP). Tenofovir disoproxil fumarate (TDF)/emtricitabine (FTC) is currently the only medication recommended for pre-exposure prophylaxis (PrEP) by the Centers for Disease Control and Prevention (CDC) in people at high risk for HIV acquisition. This article will review medications currently under investigation and the future landscape of PrEP therapy. Areas covered: This article will review clinical trials that have investigated nontraditional regimens of TDF/FTC, antiretroviral agents from different drug classes such as integrase strand transfer inhibitors (INSTI), nucleoside reverse transcriptase inhibitors (NRTI), and non-nucleoside reverse transcriptase inhibitors (NNRTI) as potential PrEP therapies. Expert commentary: Currently, there are several investigational drugs in the pipeline for PrEP against HIV infection. Increased utilization of PrEP therapy depends on provider identification of people at high risk for HIV transmission. Advances in PrEP development will expand options and access for people and reduce the risk of HIV acquisition.

Primary cervicovaginal melanoma is a rare malignancy associated with a high risk of recurrence. Prior studies discussing the cytomorphology of cervicovaginal melanoma have been based primarily on review of conventional Papanicolaou (Pap) smears. The aim of this study was to evaluate cervicovaginal melanomas identified in liquid-based Pap tests, in comparison with features seen on conventional Pap smear preparation. Cases of cervicovaginal melanoma identified on Pap tests with concurrent or subsequent histopathologic confirmation were collected from the Baystate Medical Center cytopathology files and personal archives of the authors over a total period of 34 years. All cytopathology (n = 6) and the available histology slides (n = 5) were reviewed. Cases were analyzed regarding clinical, histopathologic and cytomorphological findings. A total of six cases with invasive cervicovaginal melanoma diagnosed on Pap tests were identified. Most patients were postmenopausal with contact bleeding, correlating with surface ulceration (identified in biopsy/excision material in 5/5 cases). Most cases had deeply invasive tumors (5/5: modified Breslow's thickness > 5 mm and Chung's level of invasion IV/V). Pap tests included four ThinPrep and two conventional smears. Overall, ThinPrep Pap tests exhibited a higher ratio of tumor cells to background squamous cells. While all Pap tests were bloodstained, tumor diathesis was prominent only within conventional smears. Melanoma cells were present both as clusters and scattered single cells in each Pap test type. Both the preparations contained epithelioid tumor cells, whereas spindled tumor cells were seen in only two ThinPrep cases. Prominent nucleoli and binucleation of tumor cells were seen in both the preparations. Melanin pigment was identified in only ThinPrep (3/4) cases and nuclear pseudo-inclusions in one conventional Pap smear. Cell blocks were made in three ThinPrep cases and immunocytochemistry (S-100, HMB45, Melan

Prolyl Endopeptidase (PREP) is Associated With Male Reproductive Functions and Gamete Physiology in Mice.

Prolyl endopeptidase (PREP) is a serine protease which has been implicated in many biological processes, such as the maturation and degradation of peptide hormones and neuropeptides, learning and memory, cell proliferation and differentiation, and glucose metabolism. A small number of reports have also suggested PREP participation in both male and female reproduction-associated processes. In the present work, we examined PREP distribution in male germ cells and studied the effects of its knockdown (Prep(gt/gt)) on testis and sperm in adult mice. The protein is expressed and localized in elongating spermatids and luminal spermatozoa of wild type (wt) mice, as well as Sertoli, Leydig, and peritubular cells. PREP is also expressed in the head and midpiece of epididymal spermatozoa, whereas the remaining tail region shows a weaker signal. Furthermore, testis weight, histology of seminiferous tubules, and epididymal sperm parameters were assessed in wt and Prep(gt/gt) mice: wild type testes have larger average tubule and lumen diameter; in addition, lumenal composition of seminiferous tubules is dissimilar between wt and Prep(gt/gt), as the percentage of spermiated tubules is much higher in wt. Finally, total sperm count, sperm motility, and normal morphology are also higher in wt than in Prep(gt/gt). These results show for the first time that the expression of PREP could be necessary for a correct reproductive function, and suggest that the enzyme may play a role in mouse spermatogenesis and sperm physiology. © 2015 Wiley Periodicals, Inc.

Biochemistry of the tale transcription factors PREP, MEIS, and PBX in vertebrates.

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.

2014-01-01

Background The Institute of Medicine report on potential reduced exposure products (PREPs) recommends that advertising and labelling be regulated to prevent explicitly or implicitly false or misleading claims. Belief that a product is less harmful may increase use or prevent smoking cessation. Objective To determine the effect of altering advertisement features on smokers’ beliefs of the harm exposure from a PREP. Methods A Quest advertisement was digitally altered using computer software and presented to participants using web-based television recruitment contracted through a survey company. 500 current smokers completed demographic and smoking history questions, were randomised to view one of three advertisement conditions, then completed eight items assessing their beliefs of the harmfulness of the product. Advertisement conditions included the original, unaltered advertisement; a “red” condition where the cigarette packages were digitally altered to the colour red, implying increased harm potential; and a “no text” condition where all text was removed to reduce explicit product information. Polytomous logistic regression, using “incorrect,” “unsure” and “correct” as outcomes, and advertisement type and covariates as predictors, was used for analyses. Results Participants randomised to the “no text” advertisement were less likely to be incorrect in their beliefs that Quest cigarettes are lower in tar, less addictive, less likely to cause cancer, have fewer chemicals, healthier and make smoking safer. Conclusions Smokers can form false beliefs about the harmfulness of PREP products based on how the PREPs are marketed. Careful examination must be undertaken to provide empirical evidence to better formulate regulatory principles of PREP advertising. PMID:18768457

Advertisement conditions included the original, unaltered advertisement; a "red" condition where the cigarette packages were digitally altered to the colour red, implying increased harm potential; and a "no text" condition where all text was removed to reduce explicit product information. Polytomous logistic regression, using "incorrect," "unsure" and "correct" as outcomes, and advertisement type and covariates as predictors, was used for analyses. Participants randomised to the "no text" advertisement were less likely to be incorrect in their beliefs that Quest cigarettes are lower in tar, less addictive, less likely to cause cancer, have fewer chemicals, are healthier and make smoking safer. Smokers can form false beliefs about the harmfulness of PREP products based on how the PREPs are marketed. Careful examination must be undertaken to provide empirical evidence to better formulate regulatory principles of PREP advertising.

In the USA, men who have sex with men (MSM) in primary partnerships are at elevated risk for human immunodeficiency virus (HIV) infection. Pre-exposure prophylaxis (PrEP), a new biomedical prevention strategy, has potential to reduce HIV transmission. This study examined predictors of PrEP adoption intentions among HIV-negative MSM in primary partnerships. The sample included HIV-negative MSM (n = 164) who participated in an ongoing cross-sectional study with an in-person interview examining PrEP adoption intentions. Higher HIV risk perception, intimacy motivations for condomless sex, recent condomless anal sex with outside partners, education, and age were each independently associated with PrEP adoption intentions. In a multivariate model, only age, education, and intimacy motivations for condomless sex were significantly associated with PrEP adoption intentions. Intimacy motivations may play a central role in PrEP adoption for MSM couples. Incorporating relationship dynamics into biomedical strategies is a promising avenue for research and intervention.

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. None of these indicators showed significant trend during the follow-up, although we found a tendency toward decrease (p = .19) of the

Pre-exposure prophylaxis (PrEP) is efficacious to prevent HIV infection, however, uptake among young men who have sex with men (YMSM) is relatively low. The purpose of this study was to describe PrEP use and related factors in a representative sample of YMSM in two cities, Chicago and Houston. YMSM, ages 16-29, were recruited via respondent-driven sampling (RDS) from 2014 to 2016. Correlates of PrEP uptake were assessed in weighted multivariable logistic regression models. A total of 12.2% of participants (of 394) reported ever taking PrEP; Black YMSM had the lowest rates of uptake (4.7%) and Whites the highest (29.5%). In a multivariable regression model, having an HIV positive sex partner, reporting recent group sex, peer network size, and city (Chicago) were significantly and positively associated with use of PrEP, while Black race was negatively associated with it. Given evidence of racial/ethnic disparities in PrEP uptake in this study, further research is needed to identify potential mechanisms of action and points of intervention.

Gynecological applications of helical CT using SmartPrep

Sakurada, Akira; Kakizaki, Dai; Abe, Kimihiko [Tokyo Medical Coll. (Japan)

SmartPrep is software program for scanning a given region of interest (ROI) at optimal contrast density. An operator can arbitrarily define ROI and preset the CT value at which scanning should be started. After the injection of a contrast medium, system conducts continuous monitoring of the ROI and the operator starts helical scanning of the planned region when the present CT value has been reached. In comparison with conventional helical CT that requires a period of time from the beginning of contrast medium injection to the beginning of scanning, SmartPrep minimizes personal error and better depicts the artery-predominant phase under optimal conditions. In this study we examine the usefulness of contrast-enhanced helical CT using SmartPrep in the evaluation of gynecological disease. When the contrast medium was injected into the dorsal vein of the hand at a rate of 3 ml/sec, strong staining of pelvic arteries was observed in the CT images started at 17 to 23 sec after injection. The early-phase helical CT obtained under these conditions provided good depiction of lesions in cases of placenta accreta and invasive mole, as well as clear demonstration of tumor angiogenesis and evaluation of laterality in cases of cervical cancer. Comparison of the early and delayed phase also facilitated easier evaluation of lymph nodes than conventional comparison of simple and contrast-enhanced CT. The results thus suggest the usefulness of contrast-enhanced helical CT using SmartPrep in gynecology. (author)

Comparing the impact of increasing condom use or HIV pre-exposure prophylaxis (PrEP use among female sex workers

Full Text Available 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.

Pre-Exposure Prophylaxis: A Narrative Review of Provider Behavior and Interventions to Increase PrEP Implementation in Primary Care.

Silapaswan, Andrew; Krakower, Douglas; Mayer, Kenneth H

Since FDA approval of HIV pre-exposure prophylaxis (PrEP) for HIV prevention, attention has been focused on PrEP implementation. The CDC estimates that 1.2 million U.S. adults might benefit from PrEP, but only a minority are using PrEP, so there is a significant unmet need to increase access for those at risk for HIV. Given the large numbers of individuals who have indications for PrEP, there are not enough practicing specialists to meet the growing need for providers trained in providing PrEP. Moreover, since PrEP is a preventive intervention for otherwise healthy individuals, primary care providers (PCPs) should be primary prescribers of PrEP. There are important clinical considerations that providers should take into account when planning to prescribe PrEP, which are highlighted in the clinical case discussed. A growing body of research also suggests that some providers may be cautious about prescribing PrEP because of concerns regarding its "real-world" effectiveness, anticipated unintended consequences associated with its use, and ambiguity as to who should prescribe it. This review summarizes findings from studies that have assessed prescriber behavior regarding provision of PrEP, and offers recommendations on how to optimize PrEP implementation in primary care settings. Development and dissemination of educational interventions for PCPs and potential PrEP users are needed, including improved methods to assist clinicians in identifying appropriate PrEP candidates, and programs to promote medication adherence and access to social and behavioral health services. PCPs are well-positioned to prescribe PrEP and coordinate health-related services to improve the sexual health of their patients, but tailored educational programs are needed.

Transgender women may face a disparate risk for HIV/AIDS compared to other groups. In 2012, Truvada was approved for daily use as HIV pre-exposure prophylaxis (PrEP). However, there is a dearth of research about barriers and facilitators to PrEP in transgender women. This paper will shed light on transgender women living in New York City's perceived and actual challenges to using PrEP and potential strategies to overcome them. After completing an initial screening process, four 90-min focus groups were completed with n = 18 transgender women. Participants were asked what they like and dislike about PrEP. Participants identified the following barriers: uncomfortable side effects, difficulty taking pills, stigma, exclusion of transgender women in advertising, and lack of research on transgender women and PrEP. Facilitators included: reducing pill size, increasing the types of available HIV prevention products, and conducting scientific studies to evaluate PrEP in transgender women.

Abstract Six randomized clinical trials have been implemented to examine the efficacy of tenofovir disoproxil fumarate (TDF) and/or TDF/emtricitabine (TDF/FTC) as preexposure prophylaxis for HIV-1 infection (PrEP). Although largely complementary, the six trials have many similar features. As the earliest results become available, an urgent question may arise regarding whether changes should be made in the conduct of the other trials. To consider this in advance, a Consultation on the Implications of HIV Pre-Exposure Prophylaxis (PrEP) Trials Results sponsored by the Division of AIDS (DAIDS) of the National Institute of Allergy and Infectious Diseases (NIAID), National Institutes of Health (NIH), and the Bill and Melinda Gates Foundation (BMGF) was held on January 29, 2010, at the Natcher Conference Center, NIH, Bethesda, MD. Participants included basic scientists, clinical researchers (including investigators performing the current PrEP trials), and representatives from the U.S. Food and Drug Administration (FDA) and the agencies sponsoring the trials: the U.S. Centers for Disease Control and Prevention (CDC), the U.S. Agency for International Development (USAID), the BMGF, and the U.S. NIH.

With the emergence of daily oral tenofovir disoproxil fumarate and emtricitabine-based pre-exposure prophylaxis (PrEP) use in Canada, questions have emerged concerning the impacts of this HIV prevention tool on gay men's social and sexual lives. We conducted small focus groups and individual qualitative interviews with 16 gay men in Toronto who were part of the 'first wave' of Canadian PrEP users. Participants were on PrEP for at least one year as part of a demonstration project (November 2014-June 2016). These participants accessed PrEP before regulatory approval by Health Canada in February 2016. The mean age of participants was 37.6 years (SD 11.02); 94% completed secondary education, and 69% were white. Sex-stigma emerged as a complex theme in men's accounts of PrEP use across three overlapping domains: (1) PrEP-related stigma, including discussions of concealment and stigma from friends, family, and sexual partners, (2) PrEP as a perceived tool for combating HIV-related stigma, where some men said that they no longer discussed HIV status with sexual partners, and (3) PrEP as illuminating structural stigma, where it was attributed to unmasking stigma related to sex and sexuality. For some participants, PrEP has allowed for liberating sex and a self-described return to normalcy-normal, exciting, pleasurable sex that was no longer reliant on condom use. Paradoxically, some men said that PrEP use both led them to experience stigmatizing reactions within their social and sexual networks, while also helping to remove stigma, shame, and fear related to HIV, sexuality, and sex with gay men living with HIV.

How Much Do We Know about Drug Resistance Due to PrEP Use? Analysis of Experts' Opinion and Its Influence on the Projected Public Health Impact.

Directory of Open Access Journals (Sweden)

Dobromir T Dimitrov

Full Text Available 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.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.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.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, individuals who become

This study examined the effectiveness of a classroom-based intervention programme aimed at improving the oral language and emergent literacy skills of students from low socio-economic, culturally diverse backgrounds within their first formal year of schooling ("prep"). Data from 137 students were available for analysis. Participants were from three primary schools located in Queensland, Australia. Eight classes were allocated to intervention and two classes acted as a business as usual control. All students received literacy instruction as per the Australian Curriculum. However, the intervention group received 24 weeks of scripted, classroom-based, book-based intervention targeting code- and meaning-related emergent literacy skills. All students were assessed individually pre- and post-intervention on code-related measures (i.e. letter identification and phonological awareness) and meaning-related measures (i.e. vocabulary, oral narrative comprehension and retell). All students made significant improvement over time for all measures. Students in the intervention group showed significantly more progress than the business as usual group on all measures, except for letter identification and oral narrative comprehension. This classroom-based book-based intervention can improve the code- and meaning-related emergent literacy skills of prep students from low socio-economic backgrounds and provide these students with the building blocks for successful literacy acquisition.

Automated SmartPrep tracker positioning in liver MRI scans

This paper presents a new method for automated SmartPrep tracker positioning in liver MRI scans. SmartPrep is used to monitor the contrast bolus signal in order to detect the arrival time of the bolus. Accurately placing the tracker in the aorta while viewing three planar scout images is a difficult task for the operator and is an important problem from the workflow standpoint. The development of an automated SmartPrep tracker would therefore help to improve workflow in liver MRI scans. In our proposed method, the aorta is detected using AdaBoost (which is a machine learning technique) by searching around the cerebral spinal fluid (CSF) in the spinal cord. Analysis of scout scan images showed that our detection method functioned properly for a variety of axial MR images without intensity correction. A total of 234 images reconstructed from the datasets of 64 volunteers were analyzed, and the results showed that the detection error for the aorta was approximately 3 mm. (author)

elPrep: High-Performance Preparation of Sequence Alignment/Map Files for Variant Calling.

Directory of Open Access Journals (Sweden)

Charlotte Herzeel

Full Text Available elPrep is a high-performance tool for preparing sequence alignment/map files for variant calling in sequencing pipelines. It can be used as a replacement for SAMtools and Picard for preparation steps such as filtering, sorting, marking duplicates, reordering contigs, and so on, while producing identical results. What sets elPrep apart is its software architecture that allows executing preparation pipelines by making only a single pass through the data, no matter how many preparation steps are used in the pipeline. elPrep is designed as a multithreaded application that runs entirely in memory, avoids repeated file I/O, and merges the computation of several preparation steps to significantly speed up the execution time. For example, for a preparation pipeline of five steps on a whole-exome BAM file (NA12878, we reduce the execution time from about 1:40 hours, when using a combination of SAMtools and Picard, to about 15 minutes when using elPrep, while utilising the same server resources, here 48 threads and 23GB of RAM. For the same pipeline on whole-genome data (NA12878, elPrep reduces the runtime from 24 hours to less than 5 hours. As a typical clinical study may contain sequencing data for hundreds of patients, elPrep can remove several hundreds of hours of computing time, and thus substantially reduce analysis time and cost.

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.

Brazil's response to the HIV epidemic now includes free access to preexposure prophylaxis (PrEP) to populations at substantial risk for HIV infection including men who have sex with men (MSM). We used nationally representative demographic, epidemiologic, and surveillance data to offer estimates for the number of MSM at substantial risk for HIV infection who might be eligible and willing to use PrEP in Brazil. Starting from the age/sex-stratified population, we calculated the number of men aged 15 to 64 years, in 5-year age groups, and the proportion of those who report sex with other men during their lifetime. We focused on 11 cities (representing all regions) that are responsible for a significant fraction of the HIV burden of the country and used city-specific HIV prevalence estimates to infer the fraction of MSM who are HIV-negative. We then derived the proportion of HIV-negative MSM under substantial risk for HIV infection defined as having unprotected receptive anal intercourse in the 6 months before study participation. Finally, PrEP uptake among the eligible was inferred from the PrEP Brazil study. Our results show that PrEP demand in these 11 cities is of 66,120 men aged 15 to 64 years. When we consider the lower and upper bounds for the available parameters, we find that PrEP demand in these 11 cities might vary from 33,378 to 97,962 men. If PrEP is restricted to those aged 15 to 49 years, demand drops by 20%. PrEP demand varies considerably by city, mostly because of the differences in population size and city-specific HIV prevalence. We have shed light on the probable size of PrEP demand in Brazil certain that the incorporation of PrEP as part of Brazil's combination prevention for populations at substantial risk for HIV infection is a necessary challenge. PrEP will not only prevent HIV infections, it will also expand testing among the most vulnerable with the added benefit of offering combination prevention for the uninfected and immediate treatment for

Prep1, A Homeodomain Transcription Factor Involved in Glucose and Lipid Metabolism

Directory of Open Access Journals (Sweden)

Francesco Oriente

2018-06-01

Full Text Available The three-amino acid loop extension (TALE homeodomain proteins are a family of transcription factor including the mammalian Pbx, MEIS and Prep proteins. TALE proteins can bind other transcription factors such as Pdx-1 and play an important role in the regulation of glucose metabolism. Experiments performed in mutant mice have shown that while the single Pbx1 or Pdx-1 knockout mice feature pancreatic islet malformations, impaired glucose tolerance and hypoinsulinemia, the trans-heterozygous Pbx1+/−Pdx1+/− mice develop age-dependent overt diabetes mellitus. In contrast, Prep1 plays a different role with respect to these proteins. Indeed, Prep1 hypomorphic mice, expressing low levels of protein, feature pancreatic islet hypoplasia accompanied by hypoinsulinemia similar to Pbx1 or Pdx1. Nevertheless, these animals show increased insulin sensitivity in skeletal muscle, liver and adipose tissue accompanied by protection from streptozotocin-induced diabetes. In addition, Prep1 hypomorphic mice feature reduced triglyceride synthesis and do not develop steatohepatitis after a methionine and coline deficient diet. In this review we have underlined how important metabolic functions are controlled by TALE proteins, in particular by Prep1, leading to hypothesis that its suppression might represent beneficial effect in the care of metabolic diseases.

We aimed to assess HIV pre-exposure prophylaxis (PrEP) awareness and prescribing practices among Washington State medical providers from diverse professional disciplines and practice types. In May 2016, we administered an anonymous online survey to licensed medical practitioners who provide primary, longitudinal, walk-in, emergency, obstetric, gynecologic, sexually transmitted infection (STI), or family planning care. Of 735 eligible providers, 64.8% had heard of PrEP. Younger providers and providers with a Doctor of Medicine (MD) degree were more likely to be aware of PrEP compared to older providers (p=0.0001) and providers of other training backgrounds (Advanced Registered Nurse Practitioner [ARNP], Doctor of Osteopathic Medicine [DO], or Physician Assistant [PA]) (p=0.04). Among providers aware of PrEP, most frequent reported concerns about prescribing were adherence (46.0%) and costs (42.9%). Providers felt very (20.1%) or somewhat (33.8%) comfortable discussing PrEP overall, but very (26.8%) or somewhat (44.7%) uncomfortable discussing cost and insurance issues. The 124 PrEP prescribers reported a median of 2 (range 1-175, total 1,142) patients prescribed PrEP. Prior authorizations and insurance denials had prevented prescriptions for 28.7% and 12.1% of prescribers, respectively. Interventions to improve PrEP access should include education to inform medical providers about PrEP, with particular attention to provider types less likely to be aware. Continued efforts to eliminate cost and insurance barriers and educate providers regarding financial resources would help improve PrEP access.

Zakocs, Ronda; Freire, Kimberley E.

2018-01-01

Background The DELTA PREP Project aimed to build the prevention capacity of 19 state domestic violence coalitions by offering eight supports designed to promote prevention integration over a 3-year period: modest grant awards, training events, technical assistance, action planning, coaching hubs, the Coalition Prevention Capacity Assessment, an online workstation, and the online documentation support system. Objectives Using quantitative and qualitative data, we sought to explain how coalitions integrated prevention within their structures and functions and document how DELTA PREP supports contributed to coalitions’ integration process. Results We found that coalitions followed a common pathway to integrate prevention. First, coalitions exhibited precursors of organizational readiness, especially having prevention champions. Second, coalitions engaged in five critical actions: engaging in dialogue, learning about prevention, forming teams, soliciting input from the coalition, and action planning. Last, by engaging in these critical actions, coalitions enhanced two key organizational readiness factors—developing a common understanding of prevention and an organizational commitment to prevention. We also found that DELTA PREP supports contributed to coalitions’ abilities to integrate prevention by supporting learning about prevention, fostering a prevention team, and engaging in action planning by leveraging existing opportunities. Two DELTA PREP supports—coaching hubs and the workstation—did not work as initially intended. From the DELTA PREP experience, we offer several lessons to consider when designing future prevention capacity-building initiatives. PMID:26245934

African HIV serodiscordant couples often desire pregnancy, despite sexual HIV transmission risk during pregnancy attempts. Pre-exposure prophylaxis (PrEP) and antiretroviral therapy (ART) reduce HIV risk and can be leveraged for safer conception but how well these strategies are used for safer conception is not known. We conducted an open-label demonstration project of the integrated delivery of PrEP and ART among 1013 HIV serodiscordant couples from Kenya and Uganda followed quarterly for 2 years. We evaluated fertility intentions, pregnancy incidence, the use of PrEP and ART during peri-conception, and peri-conception HIV incidence. At enrollment, 80% of couples indicated a desire for more children. Pregnancy incidence rates were 18.5 and 18.7 per 100 person years among HIV-uninfected and HIV-infected women, and higher among women who recently reported fertility intention (adjusted odds ratio 3.43, 95% CI 2.38-4.93) in multivariable GEE models. During the 6 months preceding pregnancy, 82.9% of couples used PrEP or ART and there were no HIV seroconversions. In this cohort with high pregnancy rates, integrated PrEP and ART was readily used by HIV serodiscordant couples, including during peri-conception periods. Widespread scale-up of safer conception counseling and services is warranted to respond to strong desires for pregnancy among HIV-affected men and women.

To estimate the incidence of abnormal cervical cytology by ThinPrep Pap-tests and cervical intraepithelial neoplasia (CIN) in young adult reproductive-aged Thai women. A total of 1254 women distributed in all regions of Thailand were monitored from 2002 through 2004. Women were screened for abnormal cervical cytology using the ThinPrep method every 6 months. Interpretation of cervical cytology was based on the Bethesda system, version 2001. Women who had the ThinPrep Pap results as atypical squamous cells of undetermined significance or worse underwent colposcopic examination. The ThinPrep and all cervical tissue samples obtained from diagnostic or therapeutic procedures were analyzed and reviewed by Covance Central Laboratory Service, Inc., Indianapolis, USA. The cumulative incidence of abnormal ThinPrep Pap-tests was as follows: 15.3 per 100 woman years (WY) (95% confidence interval [CI] 12.3, 18.9) at 6 months; 12.3 per 100 WY (95% CI 10.3, 14.6) at 12 months; and 11.6 per 100 WY (95% CI 10.0, 13.5) at 18 months. Of 1448.6 woman years of follow up, the incidence of CIN1 was 4.1 per 100 WY (95% CI 3.2, 5.3); CIN2 0.8 per 100 WY (95% CI 0.4, 1.4); and CIN3 0.6 per 100 WY (95% CI 0.3, 1.2). The incidence of abnormal ThinPrep Pap-test and CIN in young adult Thai women had been reported. No comparable data is available.

'PrEP is not ready for our community, and our community is not ready for PrEP': pre-exposure prophylaxis for HIV for people who inject drugs and limits to the HIV prevention response.

Pre-exposure prophylaxis for HIV, or 'PrEP', is the use of antiretroviral medicines by people who are HIV-negative to protect themselves against acquiring HIV. PrEP has shown efficacy for preventing HIV acquisition. Despite the potential, many concerns have been voiced by people who inject drugs (PWID) and their organizations. There is a need to engage with these views and ensure their integration in to policy and strategy. This paper presents PWID views on PrEP to foster the uptake of these opinions into scientific and policy debate around PrEP METHODS: Critical analysis of a report of a community consultation led by the International Network of People who Use Drugs (INPUD). The INPUD report highlights enthusiasm from PWID for PrEP, but also three main concerns: the feasibility and ethics of PrEP, its potential use as a substitute for other harm reduction strategies and how a focus on PrEP heralds a re-medicalization of HIV. Each concern relates to evidenced gaps in essential services or opposition to harm reduction and PWID human rights. People who use drugs have fundamental concerns about the potential impacts of pre-exposure prophylaxis for HIV which reflect a 'fault line' in HIV prevention: a predominance of biomedical approaches over community perspectives. Greater community engagement in HIV prevention strategy is needed, or we risk continuing to ignore the need for action on the underlying structural drivers and social context of the HIV epidemic. © 2016 Society for the Study of Addiction.

This study investigated the acceptability of daily use of free oral pre-exposure prophylaxis (PrEP) and associated factors among transgender women sex workers in Shenyang, China, following a briefing on PrEP. A total of 183 HIV negative or sero-status unknown participants completed the cross-sectional survey. The prevalence of acceptability of daily use of free oral PrEP was 61.2%. Adjusting for education level and monthly income, variables on negative attitudes toward PrEP (i.e., having concerns about the side-effects of PrEP) [Adjusted odds ratios (AOR): 0.26], perceived subjective norms (i.e., perceiving support from male partners to take PrEP) (AOR: 2.08), and perceived behavioral control (e.g., perceiving complete control over using PrEP) (AOR: 2.10-16.72) were significantly associated with acceptability of daily use of free oral PrEP. In addition, experiencing violence during sex work, perceived risk of contracting HIV from clients and probable anxiety were also significant. Future PrEP promotion campaigns should consider these factors.

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.

We report the latest structural information on PREP1 tumor suppressor, the specific "oncogene" and "tumor suppressive" signatures of MEIS1 and PREP1, the molecular rules regulating PREP1 and MEIS1 binding to DNA, and how these can change depending on the interaction with PBX1, cell-type, neoplastic transformation, and intracellular concentration. As both PREP1 and MEIS1 interact with PBX1 they functionally compete with each other. PREP1, PBX1, and MEIS1 TALE-class homeodomain transcription factors act in an interdependent and integrated way in experimental tumorigenesis. We also pool together the plethora of data available in human cancer databanks and connect them with the available molecular information. The emerging picture suggests that a similarly basic approach might be used to better dissect and define other oncogenes and suppressors and better understand human cancer. © 2017 The Authors.

Provider perspectives on PrEP for adolescent girls and young women in Tanzania: The role of provider biases and quality of care.

Directory of Open Access Journals (Sweden)

Full Text Available Oral pre-exposure prophylaxis (PrEP has the potential to reduce HIV acquisition among adolescent girls and young women (AGYW in sub-Saharan Africa. However, health care providers' (HCPs perspectives and interactions with potential clients can substantially influence effective provision of quality health services. We examine if HCPs' knowledge, attitude, and skills, as well as their perceptions of facility readiness to provide PrEP are associated with their willingness to provide PrEP to AGYW at high risk of HIV in Tanzania.A self-administered questionnaire was given to 316 HCPs from 74 clinics in two districts and 24 HCPs participated in follow-up in-depth interviews (IDIs. We conducted bivariate and multivariable Poisson regression to assess factors associated with willingness to provide PrEP to AGYW. Thematic content analysis was used to analyze the IDIs, which expanded upon the quantitative results.Few HCPs (3.5% had prior PrEP knowledge, but once informed, 61.1% were willing to prescribe PrEP to AGYW. Higher negative attitudes toward adolescent sexuality and greater concerns about behavioral disinhibition due to PrEP use were associated with lower willingness to prescribe PrEP. Qualitatively, HCPs acknowledged that biases, rooted in cultural norms, often result in stigmatizing and discriminatory care toward AGYW, a potential barrier for PrEP provision. However, better training to provide HIV services was associated with greater willingness to prescribe PrEP. Conversely, HCPs feared the potential negative impact of PrEP on the provision of existing HIV services (e.g., overburdened staff, and suggested the integration of PrEP into non-HIV services and the use of paramedical professionals to facilitate PrEP provision.Preparing for PrEP introduction requires more than solely training HCPs on the clinical aspects of providing PrEP. It requires a two-pronged strategy: addressing HCPs' biases regarding sexual health services to AGYW; and preparing

Men who have sex with men (MSM) commonly use inhaled nitrites, or poppers, though their use is a risk factor HIV seroconversion. Pre-exposure prophylaxis, or PrEP, is effective for HIV prevention, but is not widely used, and little is known regarding PrEP use and acceptability among MSM who use inhaled nitrites. We surveyed 580 MSM in Paris, France in 2016 about popper use, sexual behaviors including condomless anal intercourse (CAI), serosorting, and sexual positioning, PrEP use, PrEP candidacy, and interest in alternate PrEP delivery modalities. We included 444 HIV negative participants for the current study. 46.2% reported popper use in the prior 3 months. Using multivariate adjusted logistic regression, we found that popper users were more likely than non-users to consider themselves candidates for PrEP [adjusted relative risk ratio (aRRR) = 2.73; 95% CI 1.54-4.83], but they were not more likely to be current (aRRR = 1.54; 95% CI 0.71-3.33) or past (aRRR = 1.37; 95% CI 0.44-4.28) PrEP users. Mediation analyses indicated that increased CAI and serosorting partly explained the relationship between popper use and PrEP candidacy. There was considerable interest in alternate proposed PrEP delivery modalities, particularly long-acting injectable PrEP [adjusted risk ratio (aRR) = 1.43; 95% CI 1.15-1.79].

Before January 2016, Pre-Exposure Prophylaxis (PrEP), a new biomedical HIV-prevention tool, was only available in France via ANRS-Ipergay clinical study but informal use was reported outside this setting. PrEPage qualitative study reports profiles and experiences of participants who used PrEP outside of a biomedical trial before this prevention method was authorized. Between March 2015 and February 2016, a cross-section of twenty-four informal PrEP users, mostly MSM, was recruited to complete in-depth semi-structured interviews. While ANRS-Ipergay was still ongoing (2012-2016), participants described their initiation to PrEP, the way they used it and the difficulties they faced to acquire antiretroviral drugs in an environment where PrEP was still not widely known and often criticized . Through the testimonies, different user profiles and motivation toward informal PrEP use emerged: (a) participants who have increasing difficulties using condoms, (b) "opportunists" who tried PrEP without the intention of using it regularly and (c) participants with a risk aversion who sought additional protection against HIV. Participants chose to use PrEP and/or their usual prevention strategies depending on available supplies, type of partners and individual attitudes toward risk. The feeling of living a safer sex life helped participants to outweigh the fear of possible toxicity and drug resistance. Participants' needs and expectations about PrEP implementation in France were also presented.

As HIV prevalence climbs globally, including more than 50,000 new infections per year in the United States, we need effective HIV prevention strategies. The use of antiretrovirals for pre-exposure prophylaxis (known as “PrEP”) among high-risk HIV-uninfected persons is emerging as one such strategy. Randomized controlled trials have demonstrated that once daily oral PrEP decreased HIV incidence among at-risk MSM and African heterosexuals, including HIV serodiscordant couples. An additional randomized control trial of a pericoital topical application of antiretroviral microbicide gel reduced HIV incidence among at-risk heterosexual South African women. Two other studies in African women did not demonstrate the efficacy of oral or topical PrEP, raising concerns about adherence patterns and efficacy in this population. The FDA Antiretroviral Advisory Panel reviewed these studies and additional data in May 2012 and recommended the approval of oral tenofovir-emtricitabine for PrEP in high-risk populations. Patients may seek PrEP from their primary care providers and those on PrEP require monitoring. Thus, primary care providers should become familiar with PrEP. This review outlines the current state of knowledge about PrEP as it pertains to primary care including identification of individuals likely to benefit from PrEP, counseling to maximize adherence and minimize potential increases in risky behavior, and monitoring for potential drug toxicities, HIV acquisition, and antiretroviral drug resistance. Issues related to cost and insurance coverage are also discussed. Recent data suggest that PrEP, in conjunction with other prevention strategies, holds promise in helping to curtail the HIV epidemic.

Role of the pharmacist in pre-exposure chemoprophylaxis (PrEP therapy for HIV prevention

Directory of Open Access Journals (Sweden)

2009-03-01

Full Text Available 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. Pharmacists are well-positioned to play a key role in helping patients make choices about PrEP, managing their therapy

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.

Recent clinical trials have shown that a daily dose of oral TDF/FTC pre-exposure prophylaxis (PrEP) is effective in reducing human immunodeficiency (HIV) risk. Understanding trial participants' perspectives about retention and PrEP adherence is critical to inform future PrEP trials and the scale-up and implementation of PrEP programs. We analyzed 53 in-depth interviews conducted in April 2010 with participants in the TDF2 study, a Phase 3, randomized, double-blind, placebo-controlled clinical trial of daily oral TDF/FTC with heterosexual men and women in Francistown and Gaborone, Botswana. We examined participants' knowledge, attitudes, and experiences of the trial, identified facilitators and barriers to enrollment and retention, and compared participant responses by study site, sex, and study drug adherence. Our findings point to several factors to consider for participant retention and adherence in PrEP trials and programs, including conducting pre-enrollment education and myth reduction counseling, providing accurate estimates of participant obligations and side effect symptoms, ensuring participant understanding of the effects of non-adherence, gauging personal commitment and interest in study outcomes, and developing a strong external social support network for participants.

HIV preexposure prophylaxis (PrEP) is an effective tool in preventing HIV infection among high-risk men who have sex with men (MSM). It is unknown how effective PrEP is in the context of other implemented HIV prevention strategies, including condom use, seroadaption, and treatment as prevention (TasP). We evaluate the impact of increasing uptake of PrEP in conjunction with established prevention strategies on HIV incidence in a high-risk population of MSM through simulation. Agent-based simulation models representing the sexual behavior of high-risk, urban MSM in the United States over the period of 1 year were used to evaluate the effect of PrEP on HIV infection rates. Simulations included data for 10,000 MSM and compared increasing rates of PrEP uptake under 8 prevention paradigms: no additional strategies, TasP, condom use, seroadaptive behavior, and combinations thereof. We observed a mean of 103.2 infections per 10,000 MSM in the absence of any prevention method. PrEP uptake at 25% without any additional prevention strategies prevented 30.7% of infections. In the absence of PrEP, TasP, condom use, and seroadaptive behavior independently prevented 27.1%, 48.8%, and 37.7% of infections, respectively, and together prevented 72.2%. The addition of PrEP to the 3 aforementioned prevention methods, at 25% uptake, prevented an additional 5.0% of infections. To achieve a 25% reduction in HIV infections by 2020, HIV prevention efforts should focus on significantly scaling up access to PrEP in addition to HIV testing, access to antiretroviral therapy, and promoting condom use.

Qualitative studies suggest that social relationships play an important role in HIV pre-exposure prophylaxis (PrEP) use, but there have been few quantitative assessments of the role of social relationships in PrEP uptake or adherence. We examined the association between disclosure of study participation or LGBT identity and PrEP use in the 1603 HIV-negative participants enrolled in the iPrEx OLE study. We also evaluated the association between LGBT social group involvement and PrEP use. Study participation disclosure to parents and LGBT identity disclosure to anyone in a participant's social network were associated with greater PrEP uptake. Study participation disclosure to partners was associated with higher probability of having protective PrEP drug concentrations compared [risk difference 0.15 95% CI (0.01, 0.30)]. For each additional type of LGBT organization a participant was involved in, the probability of PrEP uptake and having protective drug concentrations increased by 0.04 [95% CI (0.03, 0.06)] and 0.04 (95% CI (0.02, 0.07)] respectively. Overall, social context was associated with PrEP use in iPrEx OLE, and should be taken into consideration when designing future PrEP implementation programs.

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. 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 people who inject drugs in

Full Text Available We aimed to understand the attitudes, preferences and acceptance of oral and parenteral PrEP among men who have sex with men (MSM in Thailand.Pre-exposure prophylaxis (PrEP, the use of antiretrovirals to prevent HIV acquisition, has shown promising results in recent trials. To assess the potential impact of this new HIV prevention method, in addition to efficacy data, we need to understand which psychosocial factors are likely to determine its uptake among members of potential user groups.Surveys of willingness to use PrEP products were administered to MSM. Spearman's rank tests were used to uncover associations between questionnaire items. Mann-Whitney tests were performed to ascertain differences between groups. Conjoint analysis was used to examine the attitudes and preferences of MSM towards PrEP attributes. Most participants were willing to consider taking PrEP (39.2% "yes, definitely" and 49.2% "yes, probably" and perceived PrEP as giving them new possibilities in their lives (38.5% "a lot of hope" and 55.8% "some hope", even after being instructed of potential side effects and costs. HIV testing was considered the most important attribute and a daily pill and longer lasting injection in the arm were the preferred routes of administration.Despite its multiple challenges, MSM in Thailand would be willing to take PrEP, even if they had to experience inconvenience and expense. If PrEP were to be implemented in Thailand, our findings show that its uptake could be considerable.

Complex and Conflicting Social Norms: Implications for Implementation of Future HIV Pre-Exposure Prophylaxis (PrEP Interventions in Vancouver, Canada.

Directory of Open Access Journals (Sweden)

Rod Knight

Full Text Available 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.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.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'.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.

HIV providers' likelihood to prescribe pre-exposure prophylaxis (PrEP) for HIV prevention differs by patient type: a short report.

Science.gov (United States)

Adams, Leah M; Balderson, Benjamin H

2016-09-01

Pre-exposure prophylaxis (PrEP), the antiretroviral treatment regimen for HIV-negative people at high risk of acquiring HIV, has demonstrated efficacy across clinical trials in several patient populations. The Centers for Disease Control (CDC) have released detailed guidelines to aid providers in prescribing PrEP for their high-risk patients, including men who have sex with men (MSM), high-risk heterosexuals, and injection drug users (IDUs). Given that much attention in PrEP has focused on MSM patients, the present study used an online survey to assess factors involved in HIV care providers' (n = 363) decisions about prescribing PrEP, along with their willingness to prescribe PrEP to patients from various risk populations (e.g., MSM, heterosexuals, IDUs). The efficacy of PrEP was an important factor in providers' decisions about prescribing PrEP, as were considerations about patients' adherence to the regimen, regular follow-up for care, and medication costs. This survey's findings also suggest that providers' willingness to prescribe PrEP varies by patient group, with providers most willing to initiate the regimen with MSM who have an HIV-positive partner, and least willing to prescribe to high-risk heterosexuals or IDUs. In the context of the current CDC recommendations for PrEP that include MSM, heterosexuals, and IDUs, examining providers' rationales for and barriers against supporting this HIV prevention strategy across patient groups merits further attention.

Full Text Available Abstract Background Over the past decade, tobacco companies have introduced cigarettes and smokeless tobacco products (known as Potential Reduced Exposure Products, PREPs with purportedly lower levels of some toxins than conventional cigarettes and smokeless products. It is essential that public health agencies monitor awareness, interest, use, and perceptions of these products so that their impact on population health can be detected at the earliest stages. Methods This paper reviews and critiques existing strategies for measuring awareness of PREPs from 16 published and unpublished studies. From these measures, we developed new surveillance items and subjected them to two rounds of cognitive testing, a common and accepted method for evaluating questionnaire wording. Results Our review suggests that high levels of awareness of PREPs reported in some studies are likely to be inaccurate. Two likely sources of inaccuracy in awareness measures were identified: 1 the tendency of respondents to misclassify "no additive" and "natural" cigarettes as PREPs and 2 the tendency of respondents to mistakenly report awareness as a result of confusion between PREPs brands and similarly named familiar products, for example, Eclipse chewing gum and Accord automobiles. Conclusion After evaluating new measures with cognitive interviews, we conclude that as of winter 2006, awareness of reduced exposure products among U.S. smokers was likely to be between 1% and 8%, with the higher estimates for some products occurring in test markets. Recommended measurement strategies for future surveys are presented.

Aarts, J.

1995-01-01

This paper describes the results of a two year project to design a model curriculum of health care informatics for Dutch higher professional education. The core of the curriculum are sixteen modules which cover the broad range of medical informatics and which are closely related to the profiles of the professions involved (nursing, physiotherapy, speech therapy, occupational therapy and dietetics). The curriculum emphasizes the need of using structured data and information to perform tasks in health care delivery and management, for which modern information technology is indispensable. The model curriculum will enable faculty to redesign existing undergraduate programs and to select the contents they see appropriate. In this way we hope that the model curriculum will contribute to an innovative attitude of future graduating health care professionals. A new three year project just has started to develop learning materials using professional health care software based on the sixteen modules of the curriculum. PMID:8563329

Antiretroviral pre-exposure prophylaxis (PrEP) is recommended to prevent HIV infection among high-risk men who have sex with men (MSM) though not available in Brazil where the HIV epidemic persists unabated in this group. This cross-sectional study describes PrEP awareness and willingness and associated factors among MSM and transvestite/transgender women (trans women) pre-screened for the PrEP Brasil study. Awareness was reported by 61.3 % of the participants and was associated with age, education, site, study period and prior HIV testing. Most participants (82.1 %) were willing to use PrEP, which was associated with site, study period, number of male condomless anal sexual partners and anal sex with HIV positive/unknown partners. PrEP information is need among young and less educated individuals. Willingness to use PrEP was high and future studies should be conducted to confirm PrEP acceptability and the characteristics of the population who chose to adopt this intervention.

Young men who have sex with men (YMSM) are disproportionately impacted by HIV. Pre-exposure prophylaxis (PrEP) is highly effective at preventing HIV acquisition. It remains unclear if PrEP use increases rates of condomless sex (ie, risk compensation), which may increase risk of infection if PrEP adherence is not optimal. This study aimed to examine whether PrEP use and PrEP adherence were associated with change in sexual risk behaviors in a large longitudinal cohort of YMSM reporting on multiple sexual partnerships over time. Data were obtained from the first 3 visits of an ongoing cohort study of YMSM in Chicago (analytic N = 953; 14.1% HIV-positive at baseline). Participants reported up to 4 sexual partnerships at each visit, including sexual behavior, PrEP use, and PrEP adherence within partnerships. YMSM reported higher rates of receptive condomless anal sex (CAS) in partnerships during which they were on PrEP compared with those when they were not on PrEP. This association was consistent across both HIV-negative and HIV-positive participants reporting on partnerships with both perceived HIV-negative/unknown and HIV-positive partners. The rate of receptive CAS was higher in PrEP nonadherent partnerships compared with non-PrEP partnerships. The rate of receptive CAS was also higher in PrEP nonadherent than adherent partnerships, but this was not statistically significant. These analyses provide compelling data suggesting that YMSM are engaging in risk compensation when on PrEP. If rates of receptive CAS are highest among YMSM who are PrEP nonadherent, PrEP as a prevention strategy could fail to curb HIV incidence among YMSM.

The use of recreational drugs while having sex is associated with increased HIV incidence among men who have sex with men (MSM). Taking a daily antiretroviral pill, or pre-exposure prophylaxis (PrEP) is a biomedical intervention to prevent HIV. However, the efficacy of PrEP is closely tied with high levels of adherence. While PrEP has the potential to reduce HIV acquisition, the use of recreational drugs may impede adherence. We explored perceptions of PrEP utilization and regimen preferences among 40 HIV-negative, MSM who reported concurrent recreational drug use and condomless anal sex with a man. Semi-structured qualitative interviews were conducted and the data were analyzed using a qualitative descriptive approach. Participants perceived that it would be challenging to take PrEP while high on crystal meth, crack, powder cocaine, ecstasy and/or GHB. However, men identified strategies for using PrEP when they were not high on these drugs, including taking the pill when they started their day and integrating PrEP into an established routine, such as when taking other medications or preparing for sex. PrEP regimen preferences seemed to be shaped by the frequency in which participants used drugs and their ability to plan for sex. Taking PrEP everyday was appealing for those who regularly engaged in sexualized recreational drug use. Accounts depict these sexual interactions as frequent but unpredictable. A daily regimen would allow them to be prepared for sex without having to plan. An event-driven regimen was acceptable to men who occasionally used recreational drugs in the context of sex. For this group, sex usually occurred was generally prearranged. Patterns of sex and recreational drug use figured largely into participants' framings of how they would use PrEP. These behaviors will likely play a role in the uptake of and adherence to PrEP among this population.

Pre-exposure Prophylaxis (PrEP) Use, Seroadaptation, and Sexual Behavior Among Men Who Have Sex with Men, San Francisco, 2004-2014.

The Food and Drug Administration approved pre-exposure prophylaxis (PrEP) to prevent HIV infection, and the Centers for Disease Control and Prevention has presented PrEP as a prevention option for groups at high risk such as men who have sex with men (MSM). Intervention data provide some information on how PrEP affects sexual behavior of MSM in trials, open label extensions, or clinics. However, it is unclear whether sexual risk and preventive behavioral patterns are changing in the population as a whole as PrEP becomes more widely available, whether due to PrEP use or other factors. We examined trends in PrEP use, numbers of condomless anal sex partners, consistent condom use, and seroadaptive strategies in San Francisco-a city which has actively promoted PrEP-using data from National HIV Behavioral Surveillance (NHBS). NHBS recruited 1211, 383, 373, and 268 HIV-negative MSM in 2004, 2008, 2011, and 2014, respectively. PrEP use increased from zero in 2004, 2008, and 2011 to 9.6 % in 2014. The proportion of men with no condomless anal sex partners dropped from 60.6 % in 2004, to 58.2 % in 2008, to 54.2 % in 2011, to 40.2 % in 2014. Consistent condom use decreased from 36.8 % in 2004, and 30.5 % in 2008 and 2011, to 18.3 % in 2014. PrEP's introduction and scale-up enters in a pre-existing trend of decreasing condom use and increasing sexually transmitted infections among MSM which may be accelerating in recent years. While PrEP use should be scaled up as a prevention option among those who would benefit most, we believe that public health officials need to be realistic about the possibility that condom use could very well continue to decline as PrEP use increases, and to an extent that may not be directly or indirectly offset by PrEP.

Abstract Oral HIV pre-exposure prophylaxis (PrEP) is a promising new biomedical prevention approach in which HIV-negative individuals are provided with daily oral antiretroviral medication for the primary prevention of HIV-1. Several clinical trials have demonstrated efficacy of oral PrEP for HIV prevention among groups at high risk for HIV, with adherence closely associated with level of risk reduction. In the United States (US), three groups have been prioritized for initial implementation of PrEP—injection drug users, men who have sex with men at substantial risk for HIV, and HIV-negative partners within serodiscordant heterosexual couples. Numerous demonstration projects involving PrEP implementation among MSM are underway, but relatively little research has been devoted to study PrEP implementation in HIV-serodiscordant heterosexual couples in the US. Such couples face a unique set of challenges to PrEP implementation at the individual, couple, and provider level with regard to PrEP uptake and maintenance, adherence, safety and toxicity, clinical monitoring, and sexual risk behavior. Oral PrEP also provides new opportunities for serodiscordant couples and healthcare providers for primary prevention and reproductive health. This article provides a review of the critical issues, challenges, and opportunities involved in the implementation of oral PrEP among HIV-serodiscordant heterosexual couples in the US.

This qualitative study explored the acceptability of HIV pre-exposure prophylaxis (PrEP) among MSM in India, and identified facilitators and barriers to future PrEP uptake. In 2014, we conducted 10 focus groups (n=61) among a purposive sample of diverse MSM recruited through community-based organizations in Chennai and Mumbai, and 10 key informant interviews with community leaders and health care providers. Participants' mean age was 26.1 years (SD 4.8); 62% completed secondary education, and 42% engaged in sex work. No focus group participants had heard of PrEP, but once explained, most reported they would likely use it. PrEP was alternately perceived as a 'back-up plan', a condom substitute, or a burden with concurrent condom use. Facilitators were potential for covert use, sex without condoms, and anxiety-less sex. Potential barriers emerged around stigma associated with PrEP use, fear of disclosures to one's family, wife, or male steady partner, and being labeled as HIV-positive or promiscuous by peers. Preferences emerged for intermittent rather than daily PrEP use, injectable PrEP, and free or subsidized access through community organizations or government hospitals. Key informants expressed additional concerns about risk compensation, non-adherence, and impact on ART availability for treatment. Demonstration projects are needed in India to support PrEP implementation tailored for at-risk MSM. Educational interventions for MSM should address concerns about PrEP effectiveness, side effects, and mitigate risk compensation. Community engagement may facilitate broad acceptability and challenge stigma around PrEP use. Importantly, provision of free or subsidized PrEP is necessary to making implementation feasible among low socioeconomic status MSM in India.

The HPTN 067/Alternative Dosing to Augment Pre-Exposure Prophylaxis Pill Taking (ADAPT) study evaluated daily and non-daily dosing schedules for oral pre-exposure prophylaxis (PrEP) to prevent HIV. A qualitative sub-study including focus groups and in-depth interviews was conducted among men who have sex with men participating in New York City to understand their experience with PrEP and study dosing schedules. The 37 sub-study participants were 68% black, 11% white, and 8% Asian; 27% were of Hispanic/Latino ethnicity. Mean age was 34 years. Themes resulting from qualitative analysis include: PrEP is a significant advance for HIV prevention; non-daily dosing of PrEP is congruent with HIV risk; and pervasive stigma connected to HIV and risk behavior is a barrier to PrEP adherence, especially for non-daily dosing schedules. The findings underscore how PrEP intersects with other HIV prevention practices and highlight the need to understand and address multidimensional stigma related to PrEP use.

Young men who have sex with men account for approximately 20% of incident HIV infections in the U.S. Antiretroviral pre-exposure prophylaxis (PrEP) administered as a daily pill has been shown to decrease HIV acquisition in at-risk individuals. New modalities for PrEP are being developed and tested, including injectable PrEP; however, acceptability of these emerging modalities has not yet been examined in youth. We conducted six focus groups with 36 young men and transgender men and women who have sex with men in Boston, Chicago, and Los Angeles in 2016 to assess interest in and preference for different PrEP modalities. Youth were purposively recruited based on diversity of age, race/ethnicity, and prior PrEP experience. Data were coded using content coding based on key domains of the interview guide, in particular around the central themes of interest in and barriers and facilitators to injectable PrEP use. Participants were knowledgeable about oral PrEP but suggested barriers to broader uptake, including stigma, marginalization, and access to information. While participants were split on preference for injectable versus oral PrEP, they agreed quarterly injections may be more manageable and better for those who have adherence difficulties and for those who engage in sex more frequently. Concerns specific to injectable PrEP included: severity/duration of side effects, pain, level of protection prior to next injection, distrust of medical system and injections, and cost. Understanding barriers to and preferences for diverse prevention modalities will allow for more HIV prevention options, improved products, and better interventions, thus allowing individuals to make informed HIV prevention choices.

Knowledge of pre-exposure prophylaxis (PrEP) continues to remain scarce among Black women who are disproportionally affected by HIV in the United States. A thematic analysis of open-ended questions from a sample of Black women (n=119) who completed a mix-methods, online, e-health study was conducted to examine the perceived advantages and disadvantages of using PrEP. Being a female controlled method, empowerment, option for women with risky sex partners, and serodiscordant couples were advantages described. Disadvantages of PrEP were identified as the complexity of the choice, encouragement of sex with risky partners, increased burden, promotion of unprotected sex, and newness of the drug.

The shared curriculum model is one of four successful models of academic progression identified through a consensus-building process facilitated by The Future of Nursing: Campaign for Action, with support from the Robert Wood Johnson Foundation, AARP, and the AARP Foundation. Seamless academic progression from the associate degree in nursing (ADN) to the baccalaureate degree in nursing (BSN) is achieved either by simultaneously revising both ADN and BSN curricula or by making targeted adjustments in ADN or BSN curricula to create a unified academic progression. Systematic vetting and definitive agreement on nursing prerequisites and corequisites, general education courses, nursing major content, and general degree requirements are necessary to ensure coordinated degree progression. A standardized set of expectations for beginning professional practice and for unique baccalaureate nursing knowledge ensures vital nursing content across the ADN-to-BSN continuum. Examples of state and regional ADN-to-BSN progression programs using the shared curriculum model are highlighted. The shared curriculum model is a promising practical and sustainable approach to seamless ADN-to-BSN academic progression. Copyright 2015, SLACK Incorporated.

Distinguishing hypothetical willingness from behavioral intentions to initiate HIV pre-exposure prophylaxis (PrEP): Findings from a large cohort of gay and bisexual men in the U.S.

Much of the data on the acceptability of HIV Pre-Exposure Prophylaxis (PrEP) is based on willingness to take PrEP (i.e., hypothetical receptivity) rather than actual intentions (i.e., planned behavioral action) to do so. We sought to examine differences between hypothetical willingness and behavioral intentions to begin PrEP in a national sample of gay and bisexual men (GBM) across the U.S. We utilized data collected in 2015 to examine differences between those Unwilling (42.6% n = 375), Willing but not intending (41.4%, n = 365), and willing and Intending to take PrEP (15.9%, n = 140) in a multivariable, multinomial logistic regression. Men with less education had higher odds of Intending to take PrEP. Compared to men unsure about PrEP's efficacy, those who believed PrEP was at least 90% efficacious had higher odds of Intending to take PrEP. Those who saw themselves as appropriate candidates for PrEP had higher odds of Intending to take PrEP while those who saw themselves as inappropriate candidates for PrEP had lower odds of Intending to take PrEP in comparison to men unsure if they were appropriate candidates. Increased motivation for condom non-use because of perceived sexual pressure by partners was associated with higher odds of Intending to take PrEP. The groups did not differ by risk behavior nor recent STI diagnosis. Overall, the distinction between willingness and intentions to take PrEP was meaningful and may help explain disparities between PrEP acceptability and uptake. While much of the literature has focused on hypothetical willingness to take PrEP, these results highlight the importance of simultaneously assessing willingness and intentions when examining correspondence with uptake and developing interventions to increase PrEP uptake.

2017-11-21

This study aimed to identify health-promoting contents focused on HIV/Aids prevention in messages posted in a Facebook group for debates on the use of pre-exposure prophylaxis (PrEP). This was a prospective observational study using systematic non-participant observation. From July 2015 to June 2016, all the posts in the group were catalogued and formed a corpus. Everything was processed in IRaMuTeQ and analyzed by descending hierarchical classification. The collected data were grouped in three classes: (1) HIV/Aids prevention: discussing prophylaxis, treatment, target public, and side effects; (2) universal access to PrEP in Brazil: discussing government responsibilities; (3) on-line purchase of truvada: exposing a situation of vulnerability. The findings call attention to a potential public health problem and provide backing for understanding facilitators and barriers to the use of PrEP in Brazil through the identification of health-promoting content linked to individual, social, and institutional markers.

Geosocial-networking smartphone applications are commonly used by gay, bisexual, and other men who have sex with men (MSM) to meet sexual partners. The purpose of the current study was to evaluate awareness of and willingness to use pre-exposure prophylaxis (PrEP) among MSM who use geosocial-networking smartphone applications residing in New York City. Recruitment utilizing broadcast advertisements on a popular smartphone application for MSM yielded a sample of 152 HIV-uninfected MSM. Multivariable models were used to assess demographic and behavioral correlates of awareness of and willingness to use PrEP. Most participants (85.5 %) had heard about PrEP but few (9.2 %) reported current use. Unwillingness to use PrEP was associated with concerns about side effects (PR = 0.303; 95 % CI 0.130, 0.708; p = 0.006). Given that more than half (57.6 %) of participants were willing to use PrEP, future research is needed to elucidate both individual and structural barriers to PrEP use among MSM.

Does Pre-exposure prophylaxis (PrEP) for HIV prevention in men who have sex with men (MSM) change risk behavior? A systematic review.

Pre-exposure prophylaxis (PrEP) for HIV has been available since 2012. Even so, PrEP has not been widely accepted among healthcare providers and MSM some of whom are convinced that PrEP decreases condom use, and increases sexually transmitted infections (STIs). A systematic review of the state of the evidence regarding the association of PrEP with condom use, STI incidence and change in sexual risk behaviors in MSM. A structured search of databases resulted in 142 potential citations, but only ten publications met inclusion criteria and underwent data abstraction and critical appraisal. An adapted Cochrane Collaboration domain based assessment tool was used to critically appraise the methodological components of each quantitative study, and the Mixed Methods Appraisal Tool (MMAT) was used to critically appraise qualitative and mixed-methods studies. Condom use in MSM utilizing PrEP is influenced by multiple factors. Studies indicate rates of STIs in treatment and placebo groups were high. PrEP did not significantly change STI rates between baseline and follow-up. Reporting of sexual risk improved when questionnaires were completed in private by clients. Our review found that PrEP may provide an opportunity for MSM to access sexual health care, testing, treatment and counselling services. We did not find any conclusive evidence that PrEP users increase sexual risk behaviors. The perception among healthcare providers that PrEP leads to increased sexual risk behaviors has yet to be confirmed. In order to provide effective sexual health services, clinicians need to be knowledgeable about PrEP as an HIV prevention tool. This article is protected by copyright. All rights reserved.

In the USA, gay and other men who have sex with men and transgender women are disproportionately affected by HIV. Uptake of pre-exposure prophylaxis (PrEP), anti-retroviral therapy to prevent HIV-negative individuals from seroconverting if exposed to HIV, by members of this population remains low, particularly among African-Americans. We conducted two focus groups to assess responses to an online social media campaign focusing on PrEP use in New York City. We designed, produced and disseminated the campaign to address knowledge of PrEP; its physical and psychological side effects; and psychosocial barriers related to PrEP adherence and sex shaming. Focus group participants demonstrated a relatively high knowledge of PrEP, although considerable concern remained about side effects, particularly among Black participants. Participants suggested that stigma against PrEP users was declining as PrEP use became more common, but stigma remained, particularly for those not using condoms. Many focus group participants reported distrust of medical providers and were critical of the commodification of HIV prevention by the pharmaceutical industry. Participants reported that those in romantic relationships confronted unique issues regarding PrEP, namely suspicions of infidelity. Finally, Black participants spoke of the need for more tailored and sensitive representations of Black gay men in future programmes and interventions.

The uptake of pre-exposure prophylaxis (PrEP) for HIV prevention remains low. We hypothesized that a high proportion of patients presenting for HIV non-occupational post-exposure prophylaxis (nPEP) would be candidates for PrEP based on current CDC guidelines. Outcomes from a comprehensive HIV Prevention Clinic are described. We evaluated all patients who attended the HIV Prevention Clinic for nPEP between January 1, 2013 and September 30, 2014. Each patient was evaluated for PrEP candidacy based on current CDC-guidelines and subjectively based on physician opinion. Patients were then evaluated for initiation of PrEP if they met guideline suggestions. Demographic, social, and behavioral factors were then analyzed with logistic regression for associations with PrEP candidacy and initiation. 99 individuals who attended the nPEP clinic were evaluated for PrEP. The average age was 32 years (range, 18-62), 83 (84%) were male, of whom 46 (55%) men who had have sex with men (MSM). 31 (31%) met CDC guidelines for PrEP initiation, which had very good agreement with physician recommendation (kappa=0.88, 0.78-0.98). Factors associated with PrEP candidacy included sexual exposure to HIV, prior nPEP use, and lack of drug insurance (p<0.05 for all comparisons). Combining nPEP and PrEP services in a dedicated clinic can lead to identification of PrEP candidates and may facilitate PrEP uptake. Strategies to ensure equitable access of PrEP should be explored such that those without drug coverage may also benefit from this effective HIV prevention modality.

PreP+07: improvements of a user friendly tool to preprocess and analyse microarray data

Claros M Gonzalo

2009-01-01

Full Text Available Abstract Background Nowadays, microarray gene expression analysis is a widely used technology that scientists handle but whose final interpretation usually requires the participation of a specialist. The need for this participation is due to the requirement of some background in statistics that most users lack or have a very vague notion of. Moreover, programming skills could also be essential to analyse these data. An interactive, easy to use application seems therefore necessary to help researchers to extract full information from data and analyse them in a simple, powerful and confident way. Results PreP+07 is a standalone Windows XP application that presents a friendly interface for spot filtration, inter- and intra-slide normalization, duplicate resolution, dye-swapping, error removal and statistical analyses. Additionally, it contains two unique implementation of the procedures – double scan and Supervised Lowess-, a complete set of graphical representations – MA plot, RG plot, QQ plot, PP plot, PN plot – and can deal with many data formats, such as tabulated text, GenePix GPR and ArrayPRO. PreP+07 performance has been compared with the equivalent functions in Bioconductor using a tomato chip with 13056 spots. The number of differentially expressed genes considering p-values coming from the PreP+07 and Bioconductor Limma packages were statistically identical when the data set was only normalized; however, a slight variability was appreciated when the data was both normalized and scaled. Conclusion PreP+07 implementation provides a high degree of freedom in selecting and organizing a small set of widely used data processing protocols, and can handle many data formats. Its reliability has been proven so that a laboratory researcher can afford a statistical pre-processing of his/her microarray results and obtain a list of differentially expressed genes using PreP+07 without any programming skills. All of this gives support to scientists

The perceptions, motivations, and beliefs of HIV-uninfected women about pre-exposure prophylaxis (PrEP) use during pregnancy can influence its uptake and adherence. This study elicited the views of HIV-uninfected women with personal experience taking PrEP during pregnancy. Qualitative interviews were conducted with HIV-uninfected women who had personal experience taking PrEP while pregnant. Semistructured interviews were conducted with 21 HIV-uninfected Kenyan women in HIV-serodiscordant couples enrolled in an open-label PrEP demonstration project who became pregnant while using PrEP and continued PrEP through their pregnancy. Interviews were audio-recorded and transcribed into English. A qualitative descriptive analysis was performed, using a constant comparison approach to identify key themes related to PrEP use in pregnancy. Desire to remain HIV uninfected and have an HIV-free infant were strong motivators influencing continued use of PrEP during pregnancy. Supporting HIV-infected partners and childbearing within an HIV-serodiscordant relationship were also motivators. Women had challenges distinguishing normal pregnancy symptoms from PrEP side effects and were concerned that observed side effects could be signs of danger for the infant related to PrEP exposure. Health care providers were important conduits of knowledge about PrEP, and continuity of PrEP providers throughout pregnancy facilitated adherence. HIV-uninfected women in HIV-serodiscordant couples were motivated to use PrEP during pregnancy to remain HIV uninfected and to have an HIV-free child but had concerns about side effects. Health care providers will be important for PrEP messaging and adherence support in this unique population.

2011-05-01

Full Text Available The preprocessor PREP-CHEM-SRC presented in the paper is a comprehensive tool aiming at preparing emission fields of trace gases and aerosols for use in atmospheric-chemistry transport models. The considered emissions are from the most recent databases of urban/industrial, biogenic, biomass burning, volcanic, biofuel use and burning from agricultural waste sources. For biomass burning, emissions can be also estimated directly from satellite fire detections using a fire emission model included in the tool. The preprocessor provides emission fields interpolated onto the transport model grid. Several map projections can be chosen. The inclusion of these emissions in transport models is also presented. The preprocessor is coded using Fortran90 and C and is driven by a namelist allowing the user to choose the type of emissions and the databases.

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.

Women who inject drugs (WWID) are at heightened risk for HIV due to biological, behavioral, and structural factors. Pre-exposure prophylaxis (PrEP) could aid in HIV prevention for WWID. However, little is known about WWID awareness of PrEP, which is a necessary step that must occur before PrEP uptake. We report factors associated with greater awareness among WWID to identify efficient means of awareness dissemination. Data from the 2015 National HIV Behavioral Surveillance (NHBS) system cycle on injection drug use collected in New York City (NYC) were used. Bivariable analyses, using chi-squared statistics, were conducted to examine correlates of awareness of PrEP with socio-demographic, behavioral, and health care variables. Multivariable logistic regression was used to estimate adjusted associations and determine differences in awareness of PrEP. The analysis consisted of 118 WWID. Awareness of PrEP was relatively low (31%), and risk factors were high. In the last 12 months, almost two thirds (65%) reported condomless sex, approximately one third (31%) reported transactional sex, and one third (32%) reported sharing injection equipment. In multivariable logistic regression, increased PrEP awareness was associated with reported transactional sex (AOR 3.32, 95% CI 1.22-9.00) and having a conversation about HIV prevention at a syringe exchange program (SEP) (AOR 7.61, 95% CI 2.65-21.84). We did not find race, education, household income, age, binge drinking, or sexual identity to be significantly associated with PrEP awareness. Large proportions of WWID were unaware of PrEP. These findings suggest that social networks (specifically sex work and SEP networks) are an efficient means for disseminating messaging about prevention materials such as PrEP. We recommend that SEP access increase, SEP processes be adopted in other health care settings, and WWID networks be utilized to increase PrEP awareness.

No association between the PREP gene and lithium responsive bipolar disorder

Full Text Available Abstract Background Bipolar disorder (BD is a major psychiatric condition that commonly requires prophylactic and episodic treatment. Lithium (Li has been used for over 40 years now as an effective prophylactic agent. Response to Li treatment seems to be, at least in part, genetically determined. Although we ignore how Li specifically prevents mood episodes, it has previously been suggested that Li exerts an effect on the phosphoinositide pathway, and more recently, it has been proposed that Li may modulate prolyl endopeptidase (PREP. Methods In this study we carried out an association study looking at the PREP gene, located on ch 6q22. Five intronic single nucleotide polymorphisms (SNP, three coding SNPs and one SNP in the 5' UTR were investigated for their frequency in a BD sample of 180 excellent Li responders, 69 Li nonresponders and 126 controls. Genotyping was carried out using the SNaPshot reaction from Applied Biosystems, which is a modified fluorescent single base pair extension procedure. Results Following correction for multiple testing, no significant genotypic, allelic or estimated haplotypic differences were found between responders and nonresponders or between BD patients and controls. Conclusion PREP is an interesting candidate gene to investigate in genetic studies of BD, but our findings do not support the hypothesis that genetic variation in this gene plays a major role in the etiology of BD or Li response.

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.

Liver plays a key role in controlling body carbohydrate homeostasis by switching between accumulation and production of glucose and this way maintaining constant level of glucose in blood. Increased blood glucose level triggers release of insulin from pancreatic β-cells. Insulin represses hepatic glucose production and increases glucose accumulation. Insulin resistance is the main cause of type 2 diabetes and hyperglycemia. Currently thiazolidinediones (TZDs) targeting transcriptional factor PPARγ are used as insulin sensitizers for treating patients with type 2 diabetes. However, TZDs are reported to be associated with cardiovascular and liver problems and stimulate obesity. Thus, it is necessary to search new approaches to improve insulin sensitivity. A promising candidate is transcriptional factor Prep1, as it was shown earlier it could affect insulin sensitivity in variety of insulin-sensitive tissues. The aim of the present study was to evaluate a possible involvement of transcriptional factor Prep1 in control of hepatic glucose accumulation and production. We created mice with liver-specific Prep1 knockout and discovered that hepatocytes derived from these mice are much more sensitive to insulin, comparing to their WT littermates. Incubation of these cells with 100 nM insulin results in almost complete inhibition of gluconeogenesis, while in WT cells this repression is only partial. However, Prep1 doesn't affect gluconeogenesis in the absence of insulin. Also, we observed that nuclear content of gluconeogenic transcription factor FOXO1 was greatly reduced in Prep1 knockout hepatocytes. These findings suggest that Prep1 may control hepatic insulin sensitivity by targeting FOXO1 nuclear stability. Copyright © 2016 Elsevier Inc. All rights reserved.

The efficacy of pre-exposure prophylaxis (PrEP) in preventing sexual acquisition of human immunodeficiency virus (HIV) is well established. Little is known about the feasibility of PrEP implementation in middle-income settings with concentrated epidemics among men who have sex with men (MSM) and transgender women (TGW). PrEP Brasil is a prospective, multicentre, open-label demonstration project assessing PrEP delivery in the context of the Brazilian Public Health System. HIV-uninfected MSM and TGW in 3 referral centres in Rio de Janeiro and São Paulo were evaluated for eligibility and offered 48 weeks of daily emtricitabine/tenofovir for PrEP. Concentrations of tenofovir diphosphate in dried blood spot samples (DBS) at week 4 after enrolment (early adherence) were measured. Predictors of drug levels were assessed using ordinal logistic regression models considering the DBS drug level as a 3 level variable (<350 fmol/punch, ≥350-699 fmol/punch and ≥700 fmol/punch). 1,270 individuals were assessed for participation; n = 738 were potentially eligible and n = 450 were offered PrEP (PrEP uptake was 60.9%). Eligible but not enrolled individuals were younger, had lower HIV risk perception and had lower PrEP awareness. At week 4, 424 participants (of the 450 enrolled) had DBS TFV-DP concentrations, 94.1% in the protective range (≥350 fmol/punch, consistent with ≥2 pills per week), and 78% were in the highly protective range (≥700 fmol/punch, ≥4 pills per week). Participants with ≥12 years of schooling had 1.9 times the odds (95%CI 1.10-3.29) of a higher versus lower drug level than participants with <12 years of schooling. Condomless receptive anal intercourse in the prior 3 months was also associated with higher drug levels (adjusted OR = 1.78; 95% CI 1.08-2.94). The high uptake and early adherence indicate that PrEP for high-risk MSM and TGW can be successfully delivered in the context of the Brazilian Public Health System. Interventions to

The antiretroviral drug combination emtricitabine and tenofovir disoproxil fumarate (TDF/FTC) taken as pre-exposure prophylaxis (PrEP) is effective in preventing HIV infection, yet it also requires adherence and potentially decreases condom use. This study sought to examine these issues among a key population at risk of HIV infection, substance-using men who have sex with men (MSM). We conducted semi-structured interviews with an ethnically diverse sample of 30 young (aged 20-35) MSM prescribed PrEP within a large integrated healthcare system in San Francisco, who had reported recent drug use or hazardous drinking and one or more missed doses of PrEP. We explored participants' risk perception and sexual risk behavior, drug and alcohol use, and PrEP adherence in the context of substance use. Interviews were transcribed and coded using a directed content analysis approach to identify key categories and commonalities, and differences across participants. Salient subcategories included positive psychological effects of being on PrEP (e.g., decreased anxiety, feelings of empowerment), social effects (e.g., reduced HIV stigma), and reduction in overall perceptions of HIV risk. While overall reported use of condoms went down and many reported a brief period of increased condomless sex following PrEP initiation, others continued condom use with most of their sexual partners. Contextual factors influencing their decision to engage in condomless sex included how well they knew the partner and whether the partner was on PrEP or HIV antiretroviral treatment. Factors associated with poor adherence included disruptions in daily routine and use of alcohol and methamphetamine. PrEP-prescribing clinicians should support their patients in making informed decisions about condom use and identifying strategies to maximize adherence in the context of substance use.

Increasing the uptake of pre-exposure prophylaxis (PrEP) to prevent HIV acquisition among at-risk populations, such as young men who have sex with men (YMSM), is of vital importance to slowing the HIV epidemic. Stigma and negative injunctive norms, such as the so called "Truvada Whore" phenomenon, hamper this effort. We examined the prevalence and types of PrEP stigma and injunctive norm beliefs among YMSM and transgender women and associated individual and geospatial factors. A newly created measure of PrEP Stigma and Positive Attitudes was administered to 620 participants in an ongoing longitudinal cohort study. Results indicated lower stigma among White, compared to Black and Latino participants, and among participants not identifying as male. Prior knowledge about PrEP was associated with lower stigma and higher positive attitudes. PrEP stigma had significant geospatial clustering and hotspots were identified in neighborhoods with high HIV incidence and concentration of racial minorities, whereas coldspots were identified in areas with high HIV incidence and low LGBT stigma. These results provide important information about PrEP attitudes and how PrEP stigma differs between individuals and across communities.

Knowledge of pre-exposure prophylaxis (PrEP) continues to remain scarce among Black women who are disproportionally affected by HIV in the United States. A thematic analysis of open-ended questions from a sample of Black women (n=119) who completed a mix-methods, online, e-health study was conducted to examine the perceived advantages and disadvantages of using PrEP. Being a female controlled method, empowerment, option for women with risky sex partners, and serodiscordant couples were advantages described. Disadvantages of PrEP were identified as the complexity of the choice, encouragement of sex with risky partners, increased burden, promotion of unprotected sex, and newness of the drug.

Sharing of pre-exposure prophylaxis (PrEP) medications is a concern for PrEP implementation. For HIV-1 serodiscordant couples, sharing may undermine the HIV-1 prevention benefit and also cause antiretroviral resistance if taken by HIV-1 infected partners. Within a PrEP efficacy trial among HIV-1 serodiscordant couples, we assessed the occurrence of PrEP sharing by self-report and plasma tenofovir concentrations in HIV-1 infected partners. PrEP sharing was self-reported at <0.01% of visits, and 0%-1.6% of randomly selected and 0% of purposively selected specimens from HIV-1 infected participants had detectable tenofovir concentrations (median: 66.5 ng/mL, range: 1.3-292 ng/mL). PrEP sharing within HIV-1 serodiscordant couples was extremely rare.

The New South Wales (NSW) HIV Strategy 2016-2020 aims for the virtual elimination of HIV transmission in NSW, Australia, by 2020. Despite high and increasing levels of HIV testing and treatment since 2012, the annual number of HIV diagnoses in NSW has remained generally unchanged. Pre-exposure prophylaxis (PrEP) is highly effective in preventing HIV infection among gay and bisexual men (GBM) when taken appropriately. However, there have been no population-level studies that evaluate the impact of rapid PrEP scale-up in high-risk GBM. Expanded PrEP Implementation in Communities in NSW (EPIC-NSW) is a population-level evaluation of the rapid, targeted roll-out of PrEP to high-risk individuals. EPIC-NSW, is an open-label, single-arm, multi-centre prospective observational study of PrEP implementation and impact. Over 20 public and private clinics across urban and regional areas in NSW have participated in the rapid roll-out of PrEP, supported by strong community mobilization and PrEP promotion. The study began on 1 March 2016, aiming to enroll at least 3700 HIV negative people at high risk of HIV. This estimate took into consideration criteria for PrEP prescription in people at high risk for acquiring HIV as defined in the NSW PrEP guidelines. Study participants receive once daily co-formulated tenofovir disoproxil fumarate and emtricitabine (TDF/FTC) and are followed for up to 24 months. Follow-up includes: testing for HIV at 1 month, HIV and other sexually transmissible infections three-monthly, HCV annually and monitoring of renal function six-monthly. Optional online behavioural surveys are conducted quarterly. The co-primary endpoints are (i) HIV diagnoses and incidence in the cohort and (ii) HIV diagnoses in NSW. EPIC-NSW is a population-based PrEP implementation trial which targets the entire estimated population of GBM at high risk for HIV infection in NSW. It will provide a unique opportunity to evaluate the population impact of PrEP on a concentrated HIV

Treatment as prevention is expected to have a major role in reducing HIV incidence, but other prevention interventions will also be required to bring the epidemic under control, particularly among key populations. One or more forms of pre-exposure prophylaxis (PrEP) will likely play a critical role. Oral PrEP with emtricitabine-tenofovir (Truvada®) is currently available in the US and some other countries, but uptake has been slow. We review the concerns that have contributed to this slow uptake and discuss current and future research in this critical area of HIV prevention research.

In Ireland, men who have sex with men (MSM) have increased HIV risk. Pre-exposure prophylaxis (PrEP), combined with safe sex practices, can reduce HIV acquisition. We estimated MSM numbers likely to present for PrEP by applying French PrEP criteria to Irish MSM behavioural survey data. We adjusted for survey bias, calculated proportions accessing testing services and those likely to take PrEP. We estimated 1-3% of MSM in Ireland were likely to present for PrEP.

Widespread diversion of antiretroviral (ARV) medications to illicit markets has recently been documented among indigent patients in South Florida. The recent approval of ARVs for pre-exposure prophylaxis (PrEP) has the potential to broaden these illicit markets, as high-risk individuals seek ARVs without a prescription or medical supervision. Nonadherence among diverters and unsupervised use of ARVs for treatment or PrEP increase risks of treatment failure, drug resistance, and disease transmission. We report the scope of ARV diversion among substance-using men who have sex with men in South Florida. Structured interviews (N = 515) queried demographics, HIV status, mental distress, substance dependence, and sexual risks. HIV-positive participants answered questions about medical care, treatment, and ARV adherence and diversion. Median age was 39. Of 46.4% who were HIV-positive, 79.1% were prescribed ARVs. Of these, 27% reported selling/trading ARVs. Reasons for diversion were sharing/trading with friends, sale/trade for money/drugs, and sale/trade of unused medications. ARV diverters, compared to nondiverters, were more likely to be substance dependent (74.5% vs. 58.7%, p = 0.046) and have traded sex for money/drugs (60.8% vs. 32.6%, p increased risks of treatment failure, disease transmission, and PrEP failure should be carefully considered in developing policy and behavioral supports to scaling up treatment as prevention and PrEP.

To explore the acceptability of pre-exposure prophylaxis (PrEP) among gay, bisexual and men who have sex with men (MSM) and migrant African communities in Scotland, UK. Consecutive mixed qualitative methods consisting of focus groups (FGs) and in-depth interviews (IDIs) explored PrEP acceptability. Data were digitally recorded, transcribed and analysed thematically to identify anticipated and emerging themes. Participants were recruited through community sexual health and outreach support services, and from non-sexual health settings across Scotland. Inclusion criteria included identification as either MSM and/or from migrant African communities; 18 years and older; living in Scotland at the time of participation. 7 FGs were conducted (n=33): 5 with MSM (n=22) and 2 mixed-sex groups with African participants (n=11, women=8), aged 18-75 years. 34 IDIs were conducted with MSM (n=20) and African participants (n=14, women=10), aged 19-60 years. The sample included participants who were HIV-positive and HIV-negative or untested (HIV-positive FG participants, n=22; HIV-positive IDI participants, n=17). Understandings of PrEP effectiveness and concerns about maintaining regular adherence were identified as barriers to potential PrEP uptake and use. Low perception of HIV risk due to existing risk management strategies meant few participants saw themselves as PrEP candidates. Participants identified risk of other sexually transmitted infections and pregnancy as a concern which PrEP did not address for either themselves or their sexual partners. PrEP emerged as a contentious issue because of the potentially negative implications it had for HIV prevention. Many participants viewed PrEP as problematic because they perceived that others would stop using condoms if PrEP was to become available. PrEP implementation needs to identify appropriate communication methods in the context of diverse HIV literacy; address risk-reduction concerns and; demonstrate how PrEP can be part of a

The aim of this study was to assess the prevalence and risk factors predictive of dysplasia among women seen in a gynecologic oncology service with the cytologic diagnosis of atypical squamous cells of undetermined significance (ASCUS) on Papanicolaou smears obtained by the ThinPrep method. Patients with ASCUS ThinPrep Papanicolaou smears seen at the Division of Gynecologic Oncology, University of Vermont, between 1997 and 1999 were identified. The cytologic smears were reviewed and subtyped into reactive or suggestive of squamous intraepithelial lesion (SIL). The charts of these patients were reviewed and the following information was abstracted: age, gravidity, parity, menopausal status, use of hormonal replacement therapy, smoking, history of pelvic cancer, history of radiation therapy, history of abnormal Papanicolaou smear and its treatment, history of human papillomavirus (HPV) infection, and follow-up information including results of repeat Papanicolaou smears, colposcopy, and biopsies. The prevalence of dysplasia was calculated. The demographic features of women with ASCUS, reactive, were compared with those with ASCUS, SIL, using a two-sample t test, chi(2), and Fisher's exact test. Risk factors predictive of dysplasia were calculated using the odds ratio and the 95% confidence interval. P ASCUS on ThinPrep Papanicolaou smear were identified; 63 patients had ASCUS, reactive, and 63 patients had ASCUS, SIL. The demographic features of both groups were similar. The overall prevalence of dysplasia was 15.9% and was significantly higher among women with ASCUS, SIL, than among women with ASCUS, reactive (25.4% versus 6.4%, P = 0.003). The type of ASCUS cytology (reactive versus SIL), smoking, and history of HPV were significant risk factors for dysplasia (P = 0.003, 0.037, and 0. 042, respectively). The prevalence of dysplasia among women seen in a gynecologic oncology service with ASCUS cytology on ThinPrep Papanicolaou smears is 15.9%. Women with ASCUS favor

Engineering the curriculum: Towards an adaptive curriculum

cohesiveness. Without integrity, a curriculum is unlikely to be able to deliver all its required outcomes. Utilising the concepts of system dynamics and systems thinking I propose that not only is the curriculum a complex adaptive system, it is a multi-dimensional object. Adopting this notion facilitates possible interventions that may be used to monitor the curriculum and to moderate the effects of curriculum drift. I argue that using the articulated purpose of the curriculum to determine the desired outcomes of that curriculum will enhance curricular alignment, leading to improved student learning and outcomes. Furthermore, perceiving the curriculum as a multi-dimensional object reinforces the proposition that aligning the purpose and desired outcomes of each course with those of the program will achieve improved desired outcomes from the program as a whole. The original contributions to knowledge arising from this research are curriculum drift, an enhanced approach to the curricular alignment, and a multi-dimensional view of curriculum. Perhaps the most important implication of this research, is insight into how we might incorporate curriculum drift into curriculum review models. Successful incorporation has the potential to deliver increased quality of educational outcomes by enabling innovation whilst maintaining the integrity of the curriculum.

Cervical cancer screening with liquid-based cytology (LBC) has been developed as an alternative to the conventional Papanicolaou (CP) smear. Cost-effectiveness is one of the issues when evaluating LBC. Based on the results of a Dutch randomised controlled trial, we conducted cost-effectiveness threshold analyses to investigate under what circumstances manually screened ThinPrep LBC is cost-effective for screening. The MISCAN-Cervix microsimulation model and data from the Dutch NETHCON trial (including 89,784 women) were used to estimate the costs and (quality-adjusted) life years ((QA)LYs) gained for EU screening schedules, varying cost-effectiveness threshold values. Screening strategies were primary cytological screening with LBC or CP, and triage with human papillomavirus (HPV) testing. Threshold analyses showed that screening with LBC as a primary test can be cost-effective if LBC is less than 3.2 more costly per test than CP, if the sensitivity of LBC is at least 3-5 % points higher than CP, if the quality of life for women in triage follow-up is only 0.39, or if the rate of inadequate CP smears is at least 16.2 %. Regarding test characteristics and costs of LBC and CP, only under certain conditions will a change from CP to manually screened ThinPrep LBC be cost-effective. If none of these conditions are met, implementation of manually screened ThinPrep LBC seems warranted only if there are advantages other than cost-effectiveness. Further research is needed to establish whether other LBC systems will be more favorable with regard to cost-effectiveness.

Men who have sex with men (MSM) continue to be disproportionately affected by HIV in Malaysia. Recent success has been observed within demonstration projects examining the efficacy of HIV pre-exposure prophylaxis (PrEP), an antiretroviral -based medication taken by HIV-negative men to prevent sero-conversion. In order for such promising findings to be translated in real-world settings, it is important to understand the acceptability of PrEP, including perceived barriers to access or uptake. As part of a larger mixed-methods study exploring acceptability and willingness to use PrEP among MSM in Malaysia, 19 men took part in audio-recorded focus group discussions hosted by a community-based HIV organization and facilitated by a trained researcher. Discussions focussed on awareness and potential information management, general perceptions of PrEP and potential motivations or barriers to the use of PrEP, including those at the personal, social, health system or structural level. Data were transcribed verbatim and underwent a detailed thematic analysis. Rather than perceiving PrEP as a replacement for condoms in terms of having safer sex, many participants viewed it as an additional layer protection, serving as a crucial barrier to infection on occasions where condom use was intended, but did not occur. It was also perceived as more valuable to "at-risk" men, such as those in HIV sero-discordant relationships or those with a higher number of sexual partners. Elements of discussion tended to suggest that some men taking PrEP may be subject to stigma from others, on the assumption they may be promiscuous or engage in high-risk sexual behaviours. This qualitative study indicates that, broadly speaking, PrEP may be acceptable to MSM in Malaysia. However, in order for its potential to be realized, and uptake achieved, educative interventions are required to inform the target population as to the efficacy and potential, positive impact of PrEP. Given concerns for how those

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. 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. 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%). 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 community-based organizations as a means of

Full Text Available 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.

The Smart Prep technique for gadolinium-enhanced three-dimensional MR angiography (3D-MRA) was evaluated in clinical practice. By monitoring signal intensity in the region of interest (tracking volume) in the target vessel, start timing after contrast injection can be optimized using the Smart Prep technique. Successful triggering was obtained in the chest, abdomen, and pelvic areas in about 80% of the cases in this study. Failures with this technique were mainly due to changes in tracking volume caused by patient motion and respiration. We noted that the scan started earlier than expected in the thoracic aorta when part of the heart or pulmonary artery was included in the tracking volume. Thus, care must be taken in defining the size and location of the tracking volume in gadolinium-enhanced 3D-MRA using the Smart Prep technique. (author)

A Multi-US City Assessment of Awareness and Uptake of Pre-exposure Prophylaxis (PrEP) for HIV Prevention Among Black Men and Transgender Women Who Have Sex with Men.

The HIV epidemic among Black men and transgender women who have sex with men (BMTW) demands an urgent public health response. HIV point prevalence among this population ranges from 25 to 43%-a rate far exceeding any other group. Pre-exposure prophylaxis (PrEP) for HIV prevention is a very promising prevention tool; however, its full potential to slow the epidemic has yet to be realized. For the current study, random time-location sampling at Black Gay Pride Events was used to collect data from N = 1274 BMTW, from five US cities, reporting HIV-negative/unknown status. In-field HIV testing was also provided to participants. Participants were assessed on awareness and use of PrEP, health care factors, HIV testing history, psychosocial variables, and sex behaviors. About one third of participants were aware of PrEP (39%), and a small percentage of participants were users of PrEP (4.6%). In multivariable analyses, being in a relationship, testing for HIV in the past 6 months, and others being aware of one's sexuality were positively associated with PrEP awareness. Higher levels of internalized homophobia and greater numbers of female sex partners were positively associated with PrEP use, while education and condom use were negatively associated. Based on study findings, messaging and uptake of PrEP needs greater expansion and requires novel approaches for scale-up. Improving linkage to HIV testing services is likely critical for engaging BMTW with PrEP. The potential for PrEP to slow the HIV epidemic is high; however, we must strengthen efforts to ensure universal availability and uptake.

A comparison of temporal Facebook networks of young men who have sex with men (MSM), differentiated by awareness and use of preexposure prophylaxis (PrEP)

Khanna, Aditya S.; Schumm, Phil; Schneider, John A.

2016-01-01

Young Black men who have sex with men (YBMSM) are the only population in the U.S. who have experienced rising HIV incidence over the past decade. Consistent preexposure prophylaxis (PrEP) use can substantially reduce the risk of HIV acquisition. What differentiates those who become aware of PrEP, and those who do not, remains largely unknown. The social networks of YBMSM can impact their awareness of PrEP; to examine this impact, we used two waves of Facebook data from the “uConnect” study – a longitudinal cohort study of YBMSM in Chicago (n=266). While PrEP awareness increased from 45% at baseline to 75% at follow-up, its use remained low (4% and 6%). There were 88 PrEP-unaware individuals at baseline who became aware (BA) by follow-up, and 56 who remained persistently unaware (PU). While the PUs had a higher median number of total Facebook friends, the BAs had a higher median numbers of friends who participated in uConnect, who were PrEP-aware, and who practiced behaviors previously found to be associated with individual-level awareness of PrEP at baseline. The BAs also had substantially more “influential” friends. These findings demonstrate the potential of social networks in raising PrEP awareness and use among YBMSM. PMID:28003117

In many Western countries with good coverage of antiretroviral treatment (ART) programmes the annual number of HIV infections is still high and not (yet) declining among men who have sex with men (MSM). This might indicate that antiretroviral treatment roll-out alone will not turn around the course of the epidemic and that new, additional tools are needed. Antiretrovirals used as prevention tools for people not yet infected with HIV, such as pre-exposure prophylaxis (PrEP) could be such important additional tools. PrEP is a new type of biomedical prevention, which involves the use of antiretrovirals before, during and after (periods of) sexual exposure to HIV. In this review, we will focus on PrEP as a new prevention tool for MSM at high risk in Europe, including its evidence for effectiveness, challenges for implementation, ongoing European demonstration studies; as well as how PrEP relates to other existing prevention tools. In light of European Medicines Agency's recent recommendation for approval of PrEP we briefly review the potential implications. Published by the BMJ Publishing Group Limited.

The FDA has approved tenofovir-emtricitabine for use as HIV pre-exposure prophylaxis, but it is unknown how approval may affect PrEP acceptability among US men who have sex with men. We conducted 8 focus groups among 38 Rhode Island MSM, including 3 groups among 16 male sex workers and 5 groups among 22 men in the general MSM community. Participants reported wide-ranging beliefs regarding consequences and meanings of FDA approval. Some participants would not use PrEP without approval, while others perceived approval as irrelevant or less significant than other sources of information. Our results suggest that FDA approval sends a signal that directly shapes PrEP acceptability among some MSM, while indirect influences of approval may affect uptake by others. Efforts to educate MSM about PrEP can increase acceptability by incorporating information about FDA approval, and outreach strategies should consider how this information may factor into personal decisions about PrEP use.

Alcohol based surgical prep solution and the risk of fire in the operating room: a case report

Directory of Open Access Journals (Sweden)

Gupta Rajiv

2008-04-01

Full Text Available Abstract A few cases of fire in the operating room are reported in the literature. The factors that may initiate these fires are many and include alcohol based surgical prep solutions, electrosurgical equipment, flammable drapes etc. We are reporting a case of fire in the operating room while operating on a patient with burst fracture C6 vertebra with quadriplegia. The cause of the fire was due to incomplete drying of the covering drapes with an alcohol based surgical prep solution. This paper discusses potential preventive measures to minimize the incidence of fire in the operating room.

The use of long sleeves by nonscrubbed personnel in the operating room has been called into question. We hypothesized that wearing long sleeves and gloves, compared with having bare arms without gloves, while applying the skin preparation solution would decrease particulate and microbial contamination. A mock patient skin prep was performed in 3 different operating rooms. A long-sleeved gown and gloves, or bare arms, were used to perform the procedure. Particle counters were used to assess airborne particulate contamination, and active and passive microbial assessment was achieved through air samplers and settle plate analysis. Data were compared with Student's t-test or Mann-Whitney U, and P airborne contamination while the skin prep is applied, which may lead to decreased surgical site infections.

Advances in biomedical prevention strategies such as pre-exposure prophylaxis (PrEP) represent a new opportunity for reducing HIV incidence among young Black men who have sex with men, for whom the number of new HIV infections continues to rise. However, studies have documented low rates of PrEP uptake in this community. Research suggests that the peer networks of young Black men who have sex with men play important roles in their sexual health decisions. PrEP Chicago is a randomized controlled trial network intervention designed to increase PrEP uptake among young Black men who have sex with men living in Chicago. The aims of this study are twofold. Aim 1 is to estimate the effectiveness of a peer change agent intervention for (1) increasing the number of referrals made to a PrEP information line, (2) increasing the rate of PrEP adoption among non-participant peers, and (3) increasing PrEP knowledge, attitudes, and intentions among participants. Aim 2 is to determine the individual and network variables that explain peer change agent effectiveness. PrEP Chicago is a social network intervention that utilizes the influence of peer change agents to link young Black men who have sex with men in Chicago to PrEP. Young Black men who have sex with men were recruited using respondent-driven sampling. Once screened for eligibility, participants were randomly assigned to either one of two treatment sequences: (1) intervention treatment in Year 1 followed by a minimal contact attention control in Year 2 or (2) the minimal contact attention control in Year 1 followed by treatment in Year 2. The treatment consists of a PrEP/peer change agent training workshop followed by booster calls for 12 months. The attention control consists of a sex diary activity designed to help participants assess sexual risk. Psychosocial, sexual health, and network data are collected from all participants at baseline and at 12- and 24-month follow-ups. In total, 423 participants aged 18-35 have

Comparison of Plasmagel with LeucoPREP-Macrodex methods for separation of leukocytes for virus isolation.

Plasmagel (Cellular Products, Inc., Buffalo, NY), which can separate both polymorphonuclear leukocytes (PMN) and mononuclear cells from other blood components, and LeucoPREP (Becton Dickinson Immunocytometry Systems, Mountain View, CA), which can separate mononuclear cells from other blood components, were used to harvest leukocytes from whole blood for the purpose of virus isolation. Macrodex was combined with the later, in a second step, for recovery of PMN. Of 90 peripheral blood specimens examined, cytomegalovirus was recovered from 10: in six by both methods, in three from Plasmagel prepared cells only, and in one from cells from the LeucoPREP-Macrodex preparation only. Total leukocyte counts, differential counts, and leukocyte viability did not differ significantly for the two methods. Plasmagel provided an efficient, inexpensive means of harvesting leukocytes from whole blood for virus isolation.

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. Participants were recruited through advertisements 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. Across both surveys, most 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. 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.

NPT: the issues facing the Geneva PrepCom

Hautecouverture, Benjamin

2013-04-01

The second session of the Preparatory Committee (PrepCom) for the 2015 Review Conference of the Parties to the Treaty on the Non- Proliferation of Nuclear Weapons (NPT) will meet from 22 April-3 May 2013 in Geneva, and will be chaired by Ambassador Cornel Feruta of Romania. Three years on from the adoption by consensus at the end of the 8. NPT Review Conference in New York of an Action Plan on non-proliferation, disarmament, and peaceful uses of nuclear energy - the three pillars of the NPT - as well as the Middle East, this session provides the opportunity both to take stock of the commitments undertaken in 2010 and to prepare the ground for the 2015 meeting. It is first worth noting that the beginning of the 9. five-year NPT review cycle in Vienna last year was marked by tangible optimism and revealed a constructive mindset on the part of the 110 delegations present. This was largely to be expected as a result of the success of the 2010 Review Conference. The two final PrepComs of 2010 cycle (Geneva in 2008 and New York in 2009) were also deemed a success by the delegations present, characterised by the rich and constructive nature of the discussion. Overall, the tension that marred the 2005 cycle has eased over the last few years. Yet, this positive development is sadly insufficient to ensure that the Treaty remains topical. Regarding the commitments undertaken in 2010 under the Action Plan, it is well known that it was impossible for the States concerned to come together in 2012 at a conference on establishment of a weapon-of-mass-destruction-free zone (WMDFZ) in the Middle East (chapter 4, 'The Middle East, particularly implementation of the 1995 Resolution on the Middle East'). Nevertheless, in accordance with the Action Plan, H.E. Mr Jaakko Laajava was appointed as the facilitator, Finland was named as the host country, and a rigorous consultative process is underway. Moreover, the EU has maintained its commitment to support this process by

PREP KITT, System Reliability by Fault Tree Analysis. PREP, Min Path Set and Min Cut Set for Fault Tree Analysis, Monte-Carlo Method. KITT, Component and System Reliability Information from Kinetic Fault Tree Theory

International Nuclear Information System (INIS)

Vesely, W.E.; Narum, R.E.

1997-01-01

1 - Description of problem or function: The PREP/KITT computer program package obtains system reliability information from a system fault tree. The PREP program finds the minimal cut sets and/or the minimal path sets of the system fault tree. (A minimal cut set is a smallest set of components such that if all the components are simultaneously failed the system is failed. A minimal path set is a smallest set of components such that if all of the components are simultaneously functioning the system is functioning.) The KITT programs determine reliability information for the components of each minimal cut or path set, for each minimal cut or path set, and for the system. Exact, time-dependent reliability information is determined for each component and for each minimal cut set or path set. For the system, reliability results are obtained by upper bound approximations or by a bracketing procedure in which various upper and lower bounds may be obtained as close to one another as desired. The KITT programs can handle independent components which are non-repairable or which have a constant repair time. Any assortment of non-repairable components and components having constant repair times can be considered. Any inhibit conditions having constant probabilities of occurrence can be handled. The failure intensity of each component is assumed to be constant with respect to time. The KITT2 program can also handle components which during different time intervals, called phases, may have different reliability properties. 2 - Method of solution: The PREP program obtains minimal cut sets by either direct deterministic testing or by an efficient Monte Carlo algorithm. The minimal path sets are obtained using the Monte Carlo algorithm. The reliability information is obtained by the KITT programs from numerical solution of the simple integral balance equations of kinetic tree theory. 3 - Restrictions on the complexity of the problem: The PREP program will obtain the minimal cut and

Preparative HPLC-MS is often the method of choice for purification of small amounts (libraries for drug discovery. The method is robust, well proven, and widely applicable. In contrast, preparative supercritical fluid chromatography coupled with mass spectrometry (SFC-MS) has seen only slow acceptance for the same application--despite some potential scientific and economic advantages. One of the reasons for slow adoption of SFC-MS is the lack of well-proven, robust, and commercially available instrumentation. In early 2009, TharSFC (a Waters Company, Pittsburgh, PA) introduced a new fully integrated system for preparative SFC-MS: The SFC-MS Prep-100. We report herein an objective evaluation of the SFC-MS Prep-100, including tests for pump and autosampler performance, sample recovery, sample carryover, fraction triggering, detector/fraction collector synchronization, and overall robustness. Our results suggest that the SFC-MS Prep-100 represents a significant advance over previous generation instrumentation. Copyright © 2011 Society for Laboratory Automation and Screening.

Pre-exposure prophylaxis (PrEP) remains an under-utilized HIV prevention tool among men who have sex with men (MSM). To more comprehensively elucidate barriers and facilitators to PrEP use among US MSM, we conducted a systematic review of peer-reviewed published articles and content analysis of online posts about PrEP. We searched peer-reviewed databases (Medline, Web of Science, Google Scholar) using MESH headings and keywords about PrEP and/or HIV prevention from 2005 to 2015. We included original studies among MSM in the US that reported on barriers, facilitators, or other factors related to PrEP use. We also searched online posts and associated comments (news articles, opinion pieces, blogs and other social media posts) in diverse venues (Facebook, Slate Outward, Huffington Post Gay Voices, Queerty, and My PrEP Experience blog) to identify posts about PrEP. We used content analysis to identify themes and compare potential differences between the peer-reviewed literature and online posts. We identified 25 peer-reviewed articles and 28 online posts meeting inclusion criteria. We identified 48 unique barriers and 46 facilitators to using PrEP. These 94 themes fit into six overarching categories: (1) access (n = 14), (2) attitudes/beliefs (n = 24), (3) attributes of PrEP (n = 13), (4) behaviors (n = 11), (5) sociodemographic characteristics (n = 8), and (6) social network (n = 6). In all categories, analysis of online posts resulted in identification of a greater number of unique themes. Thirty-eight themes were identified in the online posts that were not identified in the peer-reviewed literature. We identified barriers and facilitators to PrEP in online posts that were not identified in a systematic review of the peer-reviewed literature. By incorporating data both from a systematic review of peer-reviewed articles and from online posts, we have identified salient and novel information about barriers to and facilitators of PrEP use.

Pre-exposure prophylaxis (PrEP) with daily oral emtricitabine and tenofovir disoproxil fumarate (FTC/TDF) prevents HIV infection. The safety and feasibility of HIV PrEP in the setting of hepatitis B virus (HBV) infection were evaluated. The Iniciativa Profilaxis Pre-Exposición study randomized 2499 HIV-negative men and transgender women who have sex with men to once-daily oral FTC/TDF versus placebo. Hepatitis serologies and transaminases were obtained at screening and at the time PrEP was discontinued. HBV DNA was assessed by polymerase chain reaction, and drug resistance was assessed by population sequencing. Vaccination was offered to individuals susceptible to HBV infection. Of the 2499 participants, 12 (0.5%; including 6 randomized to FTC/TDF) had chronic HBV infection. After stopping FTC/TDF, 5 of the 6 participants in the active arm had liver function tests performed at follow-up. Liver function tests remained within normal limits at post-stop visits except for a grade 1 elevation in 1 participant at post-stop week 12 (alanine aminotransferase = 90, aspartate aminotransferase = 61). There was no evidence of hepatic flares. Polymerase chain reaction of stored samples showed that 2 participants in the active arm had evidence of acute HBV infection at enrollment. Both had evidence of grade 4 transaminase elevations with subsequent resolution. Overall, there was no evidence of TDF or FTC resistance among tested genotypes. Of 1633 eligible for vaccination, 1587 (97.2%) received at least 1 vaccine; 1383 (84.7%) completed the series. PrEP can be safely provided to individuals with HBV infection if there is no evidence of cirrhosis or substantial transaminase elevation. HBV vaccination rates at screening were low globally, despite recommendations for its use, yet uptake and efficacy were high when offered.

Drawing primarily from business and management literature and the authors' experience, these 12 tips provide guidance to organizations, teams, and individuals involved in curriculum or program development at undergraduate, postgraduate, and continuing education levels. The tips are based around change models and approaches and can help underpin successful curriculum review, development, and delivery, as well as fostering appropriate educational innovation. A range of tools exist to support systematic program development and review, but even relatively simple changes need to take account of many factors, including the complexity of the environment, stakeholder engagement, cultural and psychological aspects, and the importance of followers.

The critical thinking curriculum model

Science.gov (United States)

Robertson, William Haviland

The Critical Thinking Curriculum Model (CTCM) utilizes a multidisciplinary approach that integrates effective learning and teaching practices with computer technology. The model is designed to be flexible within a curriculum, an example for teachers to follow, where they can plug in their own critical issue. This process engages students in collaborative research that can be shared in the classroom, across the country or around the globe. The CTCM features open-ended and collaborative activities that deal with current, real world issues which leaders are attempting to solve. As implemented in the Critical Issues Forum (CIF), an educational program administered by Los Alamos National Laboratory (LANL), the CTCM encompasses the political, social/cultural, economic, and scientific realms in the context of a current global issue. In this way, students realize the importance of their schooling by applying their efforts to an endeavor that ultimately will affect their future. This study measures student attitudes toward science and technology and the changes that result from immersion in the CTCM. It also assesses the differences in student learning in science content and problem solving for students involved in the CTCM. A sample of 24 students participated in classrooms at two separate high schools in New Mexico. The evaluation results were analyzed using SPSS in a MANOVA format in order to determine the significance of the between and within-subjects effects. A comparison ANOVA was done for each two-way MANOVA to see if the comparison groups were equal. Significant findings were validated using the Scheffe test in a Post Hoc analysis. Demographic information for the sample population was recorded and tracked, including self-assessments of computer use and availability. Overall, the results indicated that the CTCM did help to increase science content understanding and problem-solving skills for students, thereby positively effecting critical thinking.

Multiple prevention measures have the possibility of impacting HIV incidence in South Korea, including early diagnosis, early treatment, and pre-exposure prophylaxis (PrEP). We investigated how each of these interventions could impact the local HIV epidemic, especially among men who have sex with men (MSM), who have become the major risk group in South Korea. A mathematical model was used to estimate the effects of each these interventions on the HIV epidemic in South Korea over the next 40 years, as compared to the current situation. We constructed a mathematical model of HIV infection among MSM in South Korea, dividing the MSM population into seven groups, and simulated the effects of early antiretroviral therapy (ART), early diagnosis, PrEP, and combination interventions on the incidence and prevalence of HIV infection, as compared to the current situation that would be expected without any new prevention measures. Overall, the model suggested that the most effective prevention measure would be PrEP. Even though PrEP effectiveness could be lessened by increased unsafe sex behavior, PrEP use was still more beneficial than the current situation. In the model, early diagnosis of HIV infection was also effectively decreased HIV incidence. However, early ART did not show considerable effectiveness. As expected, it would be most effective if all interventions (PrEP, early diagnosis and early treatment) were implemented together. This model suggests that PrEP and early diagnosis could be a very effective way to reduce HIV incidence in South Korea among MSM.

The Norwegian Cervical Cancer Screening Program recommends screening every 3 years for women between 25 and 69 years of age. There is a large difference in the percentage of unsatisfactory samples between laboratories that use different brands of liquid-based cytology. We wished to examine if inadequate ThinPrep samples could be satisfactory by processing them with the SurePath protocol. A total of 187 inadequate ThinPrep specimens from the Department of Clinical Pathology at University Hospital of North Norway were sent to Akershus University Hospital for conversion to SurePath medium. Ninety-one (48.7%) were processed through the automated "gynecologic" application for cervix cytology samples, and 96 (51.3%) were processed with the "nongynecological" automatic program. Out of 187 samples that had been unsatisfactory by ThinPrep, 93 (49.7%) were satisfactory after being converted to SurePath. The rate of satisfactory cytology was 36.6% and 62.5% for samples run through the "gynecology" program and "nongynecology" program, respectively. Of the 93 samples that became satisfactory after conversion from ThinPrep to SurePath, 80 (86.0%) were screened as normal while 13 samples (14.0%) were given an abnormal diagnosis, which included 5 atypical squamous cells of undetermined significance, 5 low-grade squamous intraepithelial lesion, 2 atypical glandular cells not otherwise specified, and 1 atypical squamous cells cannot exclude high-grade squamous intraepithelial lesion. A total of 2.1% (4/187) of the women got a diagnosis of cervical intraepithelial neoplasia 2 or higher at a later follow-up. Converting cytology samples from ThinPrep to SurePath processing can reduce the number of unsatisfactory samples. The samples should be run through the "nongynecology" program to ensure an adequate number of cells.

Students were randomly divided into a prepCheck-supervised (self-assessment) intervention group (IG; n = 24); conventionally supervised students constituted the control group (CG; n = 23). During the preparation of three-surface (MOD) class II amalgam cavities, each IG participant could analyse a superimposed 3D image of his/her preparation against the "master preparation" using the prepCheck software. In the CG, several course instructors performed the evaluations according to pre-defined assessment criteria. After completing the course, a mandatory (blinded) practical examination was taken by all course participants (both IG and CG students), and this assessment involved the preparation of a MOD amalgam cavity. Then, optical impressions by means of a CEREC-Omnicam were taken to digitalize all examination preparations, followed by surveying and assessing the latter using prepCheck. The statistical analysis of the digitalized samples (Mann-Whitney U test) revealed no significant differences between the cavity dimensions achieved in the IG and CG (P = .406). Additionally, the sum score of the degree of conformity with the "master preparation" (maximum permissible 10% of plus or minus deviation) was comparable in both groups (P = .259). The implemented interactive digitally based, self-assessment learning tool for undergraduates appears to be equivalent to the conventional form of supervision. Therefore, such digital learning tools could significantly address the ever-increasing student to faculty ratio. © 2018 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Technology and computer models enhance the learning experience when appropriately utilized. Moreover, learning is significantly improved when effective visualization is combined with models of processes allowing for inquiry-based problem solving. Still, hands-on experiences in real scenarios result in better contextualization of related problems compared to virtual laboratories. Therefore, the role of scientific visualization, technology, and computer modeling is to enhance, not displace, the learning experience by supplementing real-world problem solving and experiences, although in some circumstances, they can adequately serve to take the place of reality. The key to improving scientific education is to embrace an inquiry-based approach that favorably uses technology. This study will attempt to evaluate the effect of adding interactive modeling to the geological sciences curriculum. An assessment tool, designed to assess student understanding of physical hydrology, was used to evaluate a curriculum intervention based on student learning with a data- and modeling-driven approach using COMSOL Multiphysics software. This intervention was implemented in an upper division and graduate physical hydrology course in fall 2012. Students enrolled in the course in fall 2011 served as the control group. Interactive modeling was added to the curriculum in fall 2012 to replace the analogous mathematical modeling done by hand in fall 2011. Pre- and post-test results were used to assess and report its effectiveness. Student interviews were also used to probe student reactions to both the experimental and control curricula. The pre- and post-tests asked students to describe the significant processes in the hydrological cycle and describe the laws governing these processes. Their ability to apply their knowledge in a real-world problem was also assessed. Since the pre- and post-test data failed to meet the assumption of normality, a non-parametric Kruskal-Wallis test was run to

1976-01-01

For the probabilistic approach to reactor safety assessment by the use of event tree and fault tree techniques it is essential to be able to estimate the probabilities of failure of the various engineered safety features provided to mitigate the effects of postulated accident sequences. The PREP, KITT and SAMPLE computer codes, which incorporate Kinetic Tree Theory, perform these calculations and have been used extensively to evaluate the reliability characteristics of engineered safety features of American nuclear reactors. Working versions of these computer codes are now available in SRD, and this report explains the merits, capabilities and ease of application of the PREP, KITT, and SAMPLE programs for the solution of system reliability problems.

On track for success: an innovative behavioral science curriculum model.

This article describes the behavioral science curriculum currently in place at the Trident/MUSC Family Medicine Residency Program. The Trident/MUSC Program is a 10-10-10 community-based, university-affiliated program in Charleston, South Carolina. Over the years, the Trident/MUSC residency program has graduated over 400 Family Medicine physicians. The current behavioral science curriculum consists of both required core elements (didactic lectures, clinical observation, Balint groups, and Resident Grand Rounds) as well as optional elements (longitudinal patient care experiences, elective rotations, behavioral science editorial experience, and scholars project with a behavioral science focus). All Trident/MUSC residents complete core behavioral science curriculum elements and are free to participate in none, some, or all of the optional behavioral science curriculum elements. This flexibility allows resident physicians to tailor the educational program in a manner to meet individual educational needs. The behavioral science curriculum is based upon faculty interpretation of existing "best practice" guidelines (Residency Review Committee-Family Medicine and AAFP). This article provides sufficient curriculum detail to allow the interested reader the opportunity to adapt elements of the behavioral science curriculum to other residency training programs. While this behavioral science track system is currently in an early stage of implementation, the article discusses track advantages as well as future plans to evaluate various aspects of this innovative educational approach.

We investigated message comprehension and message framing preferences for communicating about PrEP efficacy with US MSM. We conducted eight focus groups (n = 38) and n = 56 individual interviews with MSM in Providence, RI. Facilitators probed comprehension, credibility, and acceptability of efficacy messages, including percentages, non-numerical paraphrases, efficacy ranges versus point estimates, and success- versus failure-framed messages. Our findings indicated a range of comprehension and operational understandings of efficacy messages. Participants tended to prefer percentage-based and success-framed messages, although preferences varied for communicating about efficacy using a single percentage versus a range. Participants reported uncertainty about how to interpret numerical estimates, and many questioned whether trial results would predict personal effectiveness. These results suggest that providers and researchers implementing PrEP may face challenges in communicating with users about efficacy. Efforts to educate MSM about PrEP should incorporate percentage-based information, and message framing decisions may influence message credibility and overall PrEP acceptability.

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.

Physical analog models and demonstrations can be effective educational tools for helping instructors teach abstract concepts in the Earth, planetary, and space sciences. Reducing the learning challenges for students using physical analog models and demonstrations, however, can often increase instructors' workload and budget because the cost and time needed to produce and maintain such curriculum materials is substantial. First, this presentation describes a working model for the Modeling and Educational Demonstrations Laboratory Curriculum Materials Center (MEDL-CMC) to support instructors' use of physical analog models and demonstrations in the science classroom. The working model is based on a combination of instructional resource models developed by the Association of College & Research Libraries and by the Physics Instructional Resource Association. The MEDL-CMC aims to make the curriculum materials available for all science courses and outreach programs within the institution where the MEDL-CMC resides. The sustainability and value of the MEDL-CMC comes from its ability to provide and maintain a variety of physical analog models and demonstrations in a wide range of science disciplines. Second, the presentation then reports on the development, progress, and future of the MEDL-CMC at the University of California Los Angeles (UCLA). Development of the UCLA MEDL-CMC was funded by a grant from UCLA's Office of Instructional Development and is supported by the Department of Earth, Planetary, and Space Sciences. Other UCLA science departments have recently shown interest in the UCLA MEDL-CMC services, and therefore, preparations are currently underway to increase our capacity for providing interdepartmental service. The presentation concludes with recommendations and suggestions for other institutions that wish to start their own MEDL-CMC in order to increase educational effectiveness and decrease instructor workload. We welcome an interuniversity collaboration to

HIV acquisition during pregnancy and breastfeeding significantly contributes toward paediatric HIV infection; however, little is known about risk behaviours in HIV-uninfected pregnant and postpartum women. We conducted twenty-six in-depth-interviews between July and December 2016 using a semi-structured interview guide among HIV-uninfected pregnant and recently postpartum women at-risk of HIV acquisition (defined as reporting ≥1 of the following: partner’s serostatus unknown or HIV-infected, recent condomless sex in pregnancy, and/or alcohol use during pregnancy) who attended primary healthcare services. Our study contextualizes factors related to risky sexual behaviours during pregnancy and postpartum periods and assesses knowledge and hypothetical acceptability of pre-exposure prophylaxis (PrEP) in pregnancy. Translated and transcribed data were coded and analysed by three researchers using a thematic analysis approach. In interviews with HIV-uninfected pregnant/postpartum women at-risk of HIV acquisition, we identified common themes associated with sexual risk behaviours during pregnancy, including: lack of control over decisions in sex and condom use in pregnancy, low perceived risk (e.g. beliefs that their partner has the same HIV-negative serostatus), and socio-cultural beliefs around condom use during pregnancy (e.g. contact with sperm is essential for baby’s development). PrEP knowledge was low among HIV-uninfected pregnant and breastfeeding women, and potential acceptability was good, though primary concerns were around the potential impact on the infant. While mothers presented a clear desire to protect themselves from HIV acquisition once pregnant, they also reported lack of control, and socio-cultural beliefs, like sex is good for the baby, that increased their risk of seroconversion. Mothers had limited PrEP awareness but reported hypothetical willingness to use PrEP because of concerns over HIV acquisition and onward mother to child transmission

Pre- and post-exposure prophylaxes (PrEP and PEP) can reduce the risk of HIV acquisition, yet often are inaccessible to and underutilized by most-vulnerable populations, including sex workers in sub-Saharan Africa. Based on in-depth interviews with 21 female and 23 male HIV-negative sex workers in Mombasa, Kenya, we found that awareness and knowledge of PrEP and PEP were low, although willingness to use both was high. Participants felt PrEP would be empowering and give added protection against infection, although some expressed concerns about side effects. Despite PEP's availability, few knew about it and even fewer had used it, but most who had would use it again. Sex workers valued confidentiality, privacy, trustworthiness, and convenient location in health services and wanted thorough HIV/STI assessments. These findings suggest the importance of situating PrEP and PEP within sex worker-friendly health services and conducting outreach to promote these biomedical prevention methods for Kenyan sex workers.

Full Text Available The current study examined and compared the willingness of young Black men who have sex with men (YBMSM to accept pre-exposure prophylaxis (PrEP, adult male circumcision, and condoms for reducing their risk of HIV acquisition. The majority (67% reported unprotected receptive anal sex in the last six months. About three-quarters (71% would accept using PrEP if it was 100% effective. Cost influenced PrEP acceptance with 19% indicating acceptance at $100 per month co-pay. Of those not circumcised, 50% indicated willingness if circumcision was 100% effective. Acceptance of circumcision decreased markedly to 17% with co-pays of $100. About 73% of men were willing to use condoms if they were 100% effective and 50% indicated a willingness at the cost of $10 per month. The findings suggest that condom use promotion strategies should remain at the forefront of public health efforts to control HIV incidence among YBMSM.

The COBAS AmpliPrep instrument (Roche Diagnostics GmbH, D-68305 Mannheim, Germany) automates the entire sample preparation process of nucleic acid isolation from serum or plasma for polymerase chain reaction analysis. We report the analytical performance of the LightCycler Parvovirus B19 Quantification Kit (Roche Diagnostics) using nucleic acids isolated with the COBAS AmpliPrep instrument. Nucleic acids were extracted using the Total Nucleic Acid Isolation Kit (Roche Diagnostics) and amplified with the LightCycler Parvovirus B19 Quantification Kit. The kit combination processes 72 samples per 8-hour shift. The lower detection limit is 234 IU/ml at a 95% hit-rate, linear range approximately 104-1010 IU/ml, and overall precision 16 to 40%. Relative sensitivity and specificity in routine samples from pregnant women are 100% and 93%, respectively. Identification of a persistent parvovirus B19-infected individual by the polymerase chain reaction among 51 anti-parvovirus B19 IgM-negative samples underlines the importance of additional nucleic acid testing in pregnancy and its superiority to serology in identifying the risk of parvovirus B19 transmission via blood or blood products. Combination of the Total Nucleic Acid Isolation Kit on the COBAS AmpliPrep instrument with the LightCycler Parvovirus B19 Quantification Kit provides a reliable and time-saving tool for sensitive and accurate detection of parvovirus B19 DNA.

Little is known about safety of and adherence to intermittent HIV PrEP regimens, which may be more feasible than daily dosing in some settings. We present safety and adherence data from the first trial of an intermittent PrEP regimen among Kenyan men who have sex with men (MSM) and female sex workers (FSW). MSM and FSW were randomized to daily oral FTC/TDF or placebo, or intermittent (Monday, Friday and within 2 hours after sex, not to exceed one dose per day) oral FTC/TDF or placebo in a 2:1:2:1 ratio; volunteers were followed monthly for 4 months. Adherence was assessed with the medication event monitoring system (MEMS). Sexual activity data were collected via daily text message (SMS) queries and timeline followback interviews with a one-month recall period. Sixty-seven men and 5 women were randomized into the study. Safety was similar among all groups. Median MEMS adherence rates were 83% [IQR: 63-92] for daily dosing and 55% [IQR:28-78] for fixed intermittent dosing (p = 0.003), while adherence to any post-coital doses was 26% [IQR:14-50]. SMS response rates were low, which may have impaired measurement of post-coital dosing adherence. Acceptability of PrEP was high, regardless of dosing regimen. Adherence to intermittent dosing regimens, fixed doses, and in particular coitally-dependent doses, may be more difficult than adherence to daily dosing. However, intermittent dosing may still be appropriate for PrEP if intracellular drug levels, which correlate with prevention of HIV acquisition, can be attained with less than daily dosing and if barriers to adherence can be addressed. Additional drug level data, qualitative data on adherence barriers, and better methods to measure sexual activity are necessary to determine whether adherence to post-coital PrEP could be comparable to more standard regimens.

The cobas p 630, a fully automated pre-analytical instrument for primary tube handling recently introduced to complete the Cobas(®) TaqMan systems portfolio, was evaluated in conjunction with: the COBAS(®) AmpliPrep/COBAS(®) TaqMan HBV Test, v2.0, COBAS(®) AmpliPrep/COBAS(®) TaqMan HCV Test, v1.0 and COBAS(®) AmpliPrep/COBAS(®) TaqMan HIV Test, v2.0. The instrument performance in transferring samples from primary to secondary tubes, its impact in improving COBAS(®) AmpliPrep/COBAS(®) TaqMan workflow and hands-on reduction and the risk of possible cross-contamination were assessed. Samples from 42 HBsAg positive, 42 HCV and 42 HIV antibody (Ab) positive patients as well as 21 healthy blood donors were processed with or without automated primary tubes. HIV, HCV and HBsAg positive samples showed a correlation index of 0.999, 0.987 and of 0.994, respectively. To assess for cross-contamination, high titer HBV DNA positive samples, HCV RNA and HIV RNA positive samples were distributed in the cobas p 630 in alternate tube positions, adjacent to negative control samples within the same rack. None of the healthy donor samples showed any reactivity. Based on these results, the cobas p 630 can improve workflow and sample tracing in laboratories performing molecular tests, and reduce turnaround time, errors, and risks.

Everly, George S; Barnett, Daniel J; Links, Jonathan M

2012-01-01

There appears to be virtual universal endorsement of the need for and value of acute "psychological first aid" (PFA) in the wake of trauma and disasters. In this paper, we describe the development of the curriculum for The Johns Hopkins RAPID-PFA model of psychological first aid. We employed an adaptation of the basic framework for the development of a clinical science as recommended by Millon which entailed: historical review, theoretical development, and content validation. The process of content validation of the RAPID-PFA curriculum entailed the assessment of attitudes (confidence in the application of PFA interventions, preparedness in the application of PFA); knowledge related to the application of immediate mental health interventions; and behavior (the ability to recognize clinical markers in the field as assessed via a videotape recognition exercise). Results of the content validation phase suggest the six-hour RAPID-PFA curriculum, initially based upon structural modeling analysis, can improve confidence in the application of PFA interventions, preparedness in the application of PFA, knowledge related to the application of immediate mental health interventions, and the ability to recognize clinical markers in the field as assessed via a videotape recognition exercise.

Clinical leadership and pre-registration nursing programmes: A model for clinical leadership and a prospective curriculum implementation and evaluation research strategy.

2016-07-01

To present for wider debate a conceptual model for clinical leadership development in pre-registration nursing programmes and a proposed implementation plan. Globally, leadership in nursing has become a significant issue. Whilst there is continued support for leadership preparation in pre-registration nursing programmes, there have been very few published accounts of curriculum content and/or pedagogical approaches that foster clinical leadership development in pre-registration nursing. A doctoral research study has resulted in the creation of an overarching model for clinical leadership. A multi-method research study using theoretical and empirical literature 1974-2015, a focus group, expert opinion and a national on-line survey. A conceptual model of clinical leadership development in pre-registration nursing programme is presented, including the infinity loop of clinical leadership, an integral curriculum thread and a conceptual model: a curriculum-pedagogy nexus for clinical leadership. In order to test out usability and evaluate effectiveness, a multi method programme of research in one school of nursing in Australia is outlined. Implementation of the proposed conceptual model for clinical leadership development in pre-registration nursing programmes and a programme of (post-doctoral) research will contribute to what is known about curriculum content and pedagogy for nurse academics. Importantly, for nursing students and the profession as a whole, there is a clearer expectation of what clinical leadership might look like in the novice registered nurse. For nurse academics a model is offered for consideration in curriculum design and implementation with an evaluation strategy that could be replicated. Copyright © 2016 Elsevier Ltd.

PrEP awareness and uptake among men who have sex with men (MSM) and transgender women (TG) in Thailand remains low. Finding ways to increase HIV testing and PrEP uptake among high-risk groups is a critical priority. This study evaluates the effect of a novel Adam's Love Online-to-Offline (O2O) model on PrEP and HIV testing uptake among Thai MSM and TG and identifies factors associated with PrEP uptake. The O2O model was piloted by Adam's Love (www.adamslove.org) HIV educational and counselling website. MSM and TG reached online by PrEP promotions and interested in free PrEP and/or HIV testing services contacted Adam's Love online staff, received real-time PrEP eCounseling, and completed online bookings for receiving services at one of the four sites in Bangkok based on their preference. Auto-generated site- and service-specific e-tickets and Quick Response (QR) codes were sent to their mobile devices enabling monitoring and check-in by offline site staff. Service uptake and participant's socio-demographic and risk behaviour characteristics were analyzed. Factors associated with PrEP uptake were assessed using multiple logistic regression. Between January 10th and April 11th, 2016, Adam's Love reached 272,568 people online via the PrEP O2O promotions. 425 MSM and TG received eCounseling and e-tickets. There were 325 (76.5%) MSM and TG who checked-in at clinics and received HIV testing. Nine (2.8%) were diagnosed with HIV infection. Median (IQR) time between receiving the e-ticket and checking-in was 3 (0-7) days. Of 316 HIV-negative MSM and TG, 168 (53.2%) started PrEP. In a multivariate model, higher education (OR 2.30, 95%CI 1.14-4.66; p  = 0.02), seeking sex partners online (OR 2.05, 95%CI 1.19-3.54; p  = 0.009), being aware of sexual partners' HIV status (OR 2.37, 95%CI 1.29-4.35; p  = 0.008), ever previously using post-exposure prophylaxis (PEP) (OR 2.46, 95%CI 1.19-5.09; p  = 0.01), and enrolment at Adam's Love clinic compared to the other three sites

Safety, adherence and acceptability of intermittent tenofovir/emtricitabine as HIV pre-exposure prophylaxis (PrEP among HIV-uninfected Ugandan volunteers living in HIV-serodiscordant relationships: a randomized, clinical trial.

Full Text Available BACKGROUND: Efficacy of oral pre-exposure prophylaxis (PrEP in prevention of HIV acquisition has been evaluated using a daily regimen. However, adherence to long term daily medication is rarely perfect. Intermittent regimen may be a feasible alternative. Preclinical studies have demonstrated effectiveness of intermittent PrEP in SHIV prevention among animals. However, little is known about intermittent PrEP regimens. DESIGN: Seventy two HIV-uninfected volunteers in HIV serodiscordant couple relationships in Uganda were randomly assigned to receive daily oral Tenofovir/Emtricitabine (TDF/FTC-Truvada or placebo, or intermittent (Monday, Friday and within 2 hours after sex, not to exceed one dose per day oral TDF/FTC or placebo in a 2:1:2:1 ratio. Volunteers and study staff were blinded to drug assignment, but not to regimen assignment. METHODS: Volunteers were followed for 4 months after randomization, with monthly clinical and laboratory safety assessments and comprehensive HIV risk reduction services. Adherence was monitored using medication event monitoring system (MEMS and self-report. Sexual activity data were collected via daily short text message (SMS and self-report. HIV-specific immune responses were assessed by IFN-γ ELISPOT. RESULTS: Both daily and intermittent oral TDF/FTC regimens were well tolerated. Median MEMS adherence rates were 98% (IQR: 93-100 for daily PrEP regimen, 91% (IQR: 73-97 for fixed intermittent dosing and 45% (IQR: 20-63 for post-coital dosing. SMS response rate was 74%, but increased to 80% after excluding server outages; results may have been affected by the novelty of this measure. The majority of volunteers expressed willingness with no particular preference for either regimen. CONCLUSIONS: Both daily and intermittent oral PrEP dosing regimens were safe. Adherence was high for daily and fixed intermittent dosing; post-coital dosing was associated with poor adherence. Fixed intermittent PrEP regimens may be

Safety was similar among all groups. Median MEMS adherence rates were 83% [IQR: 63-92] for daily dosing and 55% [IQR:28-78] for fixed intermittent dosing (p = 0.003, while adherence to any post-coital doses was 26% [IQR:14-50]. SMS response rates were low, which may have impaired measurement of post-coital dosing adherence. Acceptability of PrEP was high, regardless of dosing regimen.Adherence to intermittent dosing regimens, fixed doses, and in particular coitally-dependent doses, may be more difficult than adherence to daily dosing. However, intermittent dosing may still be appropriate for PrEP if intracellular drug levels, which correlate with prevention of HIV acquisition, can be attained with less than daily dosing and if barriers to adherence can be addressed. Additional drug level data, qualitative data on adherence barriers, and better methods to measure sexual activity are necessary to determine whether adherence to post-coital PrEP could be comparable to more standard regimens.ClinicalTrials.gov NCT00971230.

Emtricitabine/tenofovir disoproxil fumarate (FTC/TDF; Truvada ® ) given as pre-exposure prophylaxis (PrEP) successfully blocks HIV when taken once daily prior to potential HIV exposure. A 22-year-old male reported difficulty swallowing FTC/TDF for PrEP and subsequently began chewing the FTC/TDF tablets. Monthly urine samples assessed using liquid chromatography-tandem mass spectrometry (LC-MS/MS) indicated tenofovir levels >1,000 ng/ml, indicative of protection from HIV acquisition, over a 48-week period. Data from observational studies of HIV-positive patients details the successful treatment of HIV using crushed FTC/TDF delivered via feeding and gastronomy tubes while small, randomized trials of healthy volunteers demonstrate bioequivalence between whole and crushed FTC/TDF.

Changing Curriculum: A Critical Inquiry into the Revision of the British Columbia Science Curriculum For Grades K-9

Science.gov (United States)

Searchfield, Mary A.

In 2010 British Columbia's Ministry of Education started the process of redesigning the provincial school curriculum, Kindergarten to Grade 12. Mandatory implementation of the new curriculum was set for the 2016/17 school year for Grades K-9, and 2017/18 for Grades 10-12. With a concerted emphasis on personalized learning and through the frame of a Know-Do-Understand curriculum model, the new curriculum aims to meet the needs of today's learners, described as living in a technology-rich, fast-paced and ever-changing world, through a concept-based and competency-driven emphasis. This thesis is a critical analysis of the BC K-9 Science curriculum as written and published, looking specifically at how science is treated as a form of knowledge, its claimed presentation as a story, and on whether the intentions claimed by the designers are matched in the curriculum's final form.

National culture has been shown to play a role in curriculum change in medical schools, and business literature has described a similar influence of organizational culture on change processes in organizations. This study investigated the impact of both national and organizational culture on successful curriculum change in medical schools internationally. The authors tested a literature-based conceptual model using multilevel structural equation modeling. For the operationalization of national and organizational culture, the authors used Hofstede's dimensions of culture and Quinn and Spreitzer's competing values framework, respectively. To operationalize successful curriculum change, the authors used two derivates: medical schools' organizational readiness for curriculum change developed by Jippes and colleagues, and change-related behavior developed by Herscovitch and Meyer. The authors administered a questionnaire in 2012 measuring the described operationalizations to medical schools in the process of changing their curriculum. Nine hundred ninety-one of 1,073 invited staff members from 131 of 345 medical schools in 56 of 80 countries completed the questionnaire. An initial poor fit of the model improved to a reasonable fit by two suggested modifications which seemed theoretically plausible. In sum, characteristics of national culture and organizational culture, such as a certain level of risk taking, flexible policies and procedures, and strong leadership, affected successful curriculum change. National and organizational culture influence readiness for change in medical schools. Therefore, medical schools considering curriculum reform should anticipate the potential impact of national and organizational culture.

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

Science.gov (United States)

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 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).

2017-09-01

Full Text Available Despite the global stabilization of the number of new HIV infections in recent years, there has been an increase in new infections among men who have sex with men. This fact indicates the lack of effectiveness of the measures and prevention campaigns established so far for this group. It is therefore necessary to implement alternative preventive measures for them. Pre-exposure pharmacological prophylaxis (PrEP is one of the best evaluated options and has had high protection rates in both clinical and real-life trials. The strategy has also shown an adequate profile in terms of safety, tolerance, adverse effects and cost-effectiveness in the studies carried out to assess this important topic.

Background HIV pre-exposure prophylaxis (PrEP), the use of antiretroviral drugs by uninfected individuals to prevent HIV infection, has demonstrated effectiveness in preventing acquisition in a high-risk population of men who have sex with men (MSM). Consequently, there is a need to understand if and how PrEP can be used cost-effectively to prevent HIV infection in such populations. Methods and Findings We developed a mathematical model representing the HIV epidemic among MSM and transwomen (male-to-female transgender individuals) in Lima, Peru, as a test case. PrEP effectiveness in the model is assumed to result from the combination of a “conditional efficacy” parameter and an adherence parameter. Annual operating costs from a health provider perspective were based on the US Centers for Disease Control and Prevention interim guidelines for PrEP use. The model was used to investigate the population-level impact, cost, and cost-effectiveness of PrEP under a range of implementation scenarios. The epidemiological impact of PrEP is largely driven by programme characteristics. For a modest PrEP coverage of 5%, over 8% of infections could be averted in a programme prioritising those at higher risk and attaining the adherence levels of the Pre-Exposure Prophylaxis Initiative study. Across all scenarios, the highest estimated cost per disability-adjusted life year averted (uniform strategy for a coverage level of 20%, US$1,036–US$4,254) is below the World Health Organization recommended threshold for cost-effective interventions, while only certain optimistic scenarios (low coverage of 5% and some or high prioritisation) are likely to be cost-effective using the World Bank threshold. The impact of PrEP is reduced if those on PrEP decrease condom use, but only extreme behaviour changes among non-adherers (over 80% reduction in condom use) and a low PrEP conditional efficacy (40%) would adversely impact the epidemic. However, PrEP will not arrest HIV transmission in

In order to analyze tasks of the death education curriculum for the public, DACUM method was used. A committee for DACUM was gathered and a survey was conducted on professors of health care, humanities and social sciences for an interdisciplinary study. In the survey used to verify the model for death education for the public, a compilation based on difficulty and importance factor shows that the 27 tasks including the psychological changes in terminally ill or suicidal patients, healing of stress, acceptance and understanding of death and suicide prevention were identified as needing to be included in the curriculum. The data thus concluded will have to be reviewed when they are applied to actual education to revise the education program to make it more appropriate.

The Influence of Curriculum, Instruction, Technology, and Social Interactions on Two Fifth-Grade Students' Epistemologies in Modeling Throughout a Model-Based Curriculum Unit

Science.gov (United States)

Baek, Hamin; Schwarz, Christina V.

2015-04-01

In the past decade, reform efforts in science education have increasingly attended to engaging students in scientific practices such as scientific modeling. Engaging students in scientific modeling can help them develop their epistemologies by allowing them to attend to the roles of mechanism and empirical evidence when constructing and revising models. In this article, we present our in-depth case study of how two fifth graders—Brian and Joon—who were students in a public school classroom located in a Midwestern state shifted their epistemologies in modeling as they participated in the enactment of a technologically enhanced, model-based curriculum unit on evaporation and condensation. First, analyses of Brian's and Joon's models indicate that their epistemologies in modeling related to explanation and empirical evidence shifted productively throughout the unit. Additionally, while their initial and final epistemologies in modeling were similar, the pathways in which their epistemologies in modeling shifted differed. Next, analyses of the classroom activities illustrate how various components of the learning ecology including technological tools, the teacher's scaffolding remarks, and students' collective activities and conversations, were marshaled in the service of the two students' shifting epistemologies in modeling. These findings suggest a nuanced view of individual learners' engagement in scientific modeling, their epistemological shifts in the practice, and the roles of technology and other components of a modeling-oriented learning environment for such shifts.

Outcomes of a Self-Regulated Learning Curriculum Model

Peters-Burton, Erin E.

2015-10-01

The purpose of this study was to describe connections among students' views of nature of science in relation to the goals of a curriculum delivered in a unique setting, one where a researcher and two teachers collaborated to develop a course devoted to teaching students about how knowledge is built in science. Students proceeded through a cycle of self-regulated phases, forethought, performance, and self-reflection, during each segment of the curriculum: (a) independent research, (b) knowledge building in the discipline of science, and (c) a citizen science project. Student views were measured at the beginning and end of the course using epistemic network analysis. The pretest map reported student understanding of science as experimentation and indicated three clusters representing the durability of knowledge, empirical evidence, and habits of mind, which were loosely connected and represented knowledge generation as external to personal thinking. The posttest map displayed a broader understanding of scientific endeavors beyond experimentation, a shift toward personal knowledge generation, and indicated a larger number of connections among three more tightly oriented clusters: empirical evidence, habits of mind, and tentativeness. Implications include the potential to build curriculum that purposefully considers reinforcing cycles of learning of the nature of science in different contexts.

Increasingly, the science education community has recognized the need for curriculum resources that support student development of authentic scientific practices, rather than focusing exclusively on content knowledge. This paper proposes a tool for teachers and researchers to assess the degree to which certain curriculum resources and lessons achieve this goal. After describing a method for reflecting on and categorizing curriculum resources, I apply the method to highlight differences across three teaching methods: Modeling Instruction, Physics Union Mathematics, and a traditional, lecture-based approach.

Stigma, medical mistrust, and perceived racism may affect PrEP awareness and uptake in black compared to white gay and bisexual men in Jackson, Mississippi and Boston, Massachusetts.

2017-11-01

Gay and bisexual men and other men who have sex with men (MSM) account for more than two thirds of new HIV infections in the U.S., with Black MSM experiencing the greatest burden. Antiretroviral pre-exposure prophylaxis (PrEP) can reduce MSM's vulnerability to HIV infection. Uptake of PrEP has been limited, particularly among racial and ethnic minority MSM. Four semi-structured focus groups with gay and bisexual men and other MSM at risk for HIV infection were convened in Boston and Jackson in late 2013. The analysis plan utilized a within-case, across-case approach to code and analyze emerging themes, and to compare results across the two cities. Participants recruited in Jackson were primarily Black gay men, while Boston participants were mostly non-Hispanic White gay men. Participants in both sites shared concerns about medication side effects and culturally insensitive health care for gay men. Jackson participants described stronger medical mistrust, and more frequently described experiences of anti-gay and HIV related stigma. Multiple addressable barriers to PrEP uptake were described. Information about side effects should be explicitly addressed in PrEP education campaigns. Providers and health departments should address medical mistrust, especially among Black gay and bisexual men and other MSM, in part by training providers in how to provide affirming, culturally competent care. Medicaid should be expanded in Mississippi to cover low-income young Black gay and bisexual men and other MSM.

A theory-based curriculum design for remediation of residents' communication skills.

Science.gov (United States)

Leung, Fok-Han; Martin, Dawn; Batty, Helen

2009-12-01

Residents requiring remediation are often deficient in communication skills, namely clinical interviewing skills. Residents have to digest large amounts of knowledge, and then apply it in a clinical interview. The patient-centered approach, as demonstrated in the Calgary-Cambridge model and Martin's Map, can be difficult to teach. Before implementing a remediation curriculum, the theoretical educational underpinnings must be sound; curriculum evaluation is often expensive. Before establishing metrics for curriculum evaluation, a starting point is to perform a mental experiment to test theoretical adherence. This article describes an experiential remedial curriculum for communication skills. Educational theories of Kolb, Knowles, Bandura, and Bloom are used to design the curriculum into theory-based design components. Kolb's experiential cycle models the natural sequence of experiencing, teaching, and learning interviewing skills. A curriculum structured around this cycle has multiple intercalations with the above educational theories. The design is strengthened by appropriately timed use of education strategies such as learning contracts, taped interviews, simulations, structured reflection, and teacher role modeling. Importantly, it also models the form of the clinical interview format desired. Through understanding and application of contemporary educational theories, a program to remediate interviewing skills can increase its potential for success.

Models and Materials: Bridging Art and Science in the Secondary Curriculum

Science.gov (United States)

Pak, D.; Cavazos, L.

2006-12-01

Creating and sustaining student engagement in science is one challenge facing secondary teachers. The visual arts provide an alternative means of communicating scientific concepts to students who may not respond to traditional formats or identify themselves as interested in science. We have initiated a three-year teacher professional development program at U C Santa Barbara focused on bridging art and science in secondary curricula, to engage students underrepresented in science majors, including girls, English language learners and non-traditional learners. The three-year format provides the teams of teachers with the time and resources necessary to create innovative learning experiences for students that will enhance their understanding of both art and science content. Models and Materials brings together ten secondary art and science teachers from six Santa Barbara County schools. Of the five participating science teachers, three teach Earth Science and two teach Life Science. Art and science teachers from each school are teamed and challenged with the task of creating integrated curriculum projects that bring visual art concepts to the science classroom and science concepts to the art classroom. Models and Materials were selected as unifying themes; understanding the concept of models, their development and limitations, is a prominent goal in the California State Science and Art Standards. Similarly, the relationship between composition, structure and properties of materials is important to both art and science learning. The program began with a 2-week institute designed to highlight the natural links between art and science through presentations and activities by both artists and scientists, to inspire teachers to develop new ways to present models in their classrooms, and for the teacher teams to brainstorm ideas for curriculum projects. During the current school year, teachers will begin to integrate science and art and the themes of modeling and materials

Evolution of the New Pathway curriculum at Harvard Medical School: the new integrated curriculum.

Science.gov (United States)

Dienstag, Jules L

2011-01-01

In 1985, Harvard Medical School adopted a "New Pathway" curriculum, based on active, adult learning through problem-based, faculty-facilitated small-group tutorials designed to promote lifelong skills of self-directed learning. Despite the successful integration of clinically relevant material in basic science courses, the New Pathway goals were confined primarily to the preclinical years. In addition, the shifting balance in the delivery of health care from inpatient to ambulatory settings limited the richness of clinical education in clinical clerkships, creating obstacles for faculty in their traditional roles as teachers. In 2006, Harvard Medical School adopted a more integrated curriculum based on four principles that emerged after half a decade of self-reflection and planning: (1) integrate the teaching of basic/population science and clinical medicine throughout the entire student experience; (2) reestablish meaningful and intensive faculty-student interactions and reengage the faculty; (3) develop a new model of clinical education that offers longitudinal continuity of patient experience, cross-disciplinary curriculum, faculty mentoring, and student evaluation; and (4) provide opportunities for all students to pursue an in-depth, faculty-mentored scholarly project. These principles of our New Integrated Curriculum reflect our vision for a curriculum that fosters a partnership between students and faculty in the pursuit of scholarship and leadership.

Integrating Spanish language training across a Doctor of Physical Therapy curriculum: a case report of one program's evolving model.

2014-12-01

As the Hispanic population continues to expand in the United States, health professionals increasingly may encounter people who speak Spanish and have limited English proficiency. Responding to these changes, various health profession educators have incorporated Spanish language training into their curricula. Of 12 doctor of physical therapy (DPT) programs identified as including elective or required Spanish courses, the program at The University of Texas at El Paso is the only one integrating required Spanish language training across the curriculum. The purpose of this case report is to describe the development, implementation, and preliminary outcomes of the evolving educational model at The University of Texas at El Paso. The University of Texas at El Paso is situated immediately across the border from Mexico. Responding to the large population with limited English proficiency in the community, faculty began to integrate required Spanish language training during a transition from a master-level to a DPT curriculum. The Spanish language curriculum pillar includes a Spanish medical terminology course, language learning opportunities threaded throughout the clinical courses, clinical education courses, and service-learning. Forty-five DPT students have completed the curriculum. Assessment methods were limited for early cohorts. Clinically relevant Spanish verbal proficiency was assessed with a practical examination in the Spanish course, a clinical instructor-rated instrument, and student feedback. Preliminary data suggested that the model is improving Spanish language proficiency. The model still is evolving. Spanish language learning opportunities in the curriculum are being expanded. Also, problems with the clinical outcome measure have been recognized. Better definition of intended outcomes and validation of a revised tool are needed. This report should promote opportunities for collaboration with others who are interested in linguistic competence. © 2014

Improved removal of blood contamination from ThinPrep cervical cytology samples for Raman spectroscopic analysis.

2018-05-01

There is an unmet need for methods to help in the early detection of cervical precancer. Optical spectroscopy-based techniques, such as Raman spectroscopy, have shown great potential for diagnosis of different cancers, including cervical cancer. However, relatively few studies have been carried out on liquid-based cytology (LBC) pap test specimens and confounding factors, such as blood contamination, have been identified. Previous work reported a method to remove blood contamination before Raman spectroscopy by pretreatment of the slides with hydrogen peroxide. The aim of the present study was to extend this work to excessively bloody samples to see if these could be rendered suitable for Raman spectroscopy. LBC ThinPrep specimens were treated by adding hydrogen peroxide directly to the vial before slide preparation. Good quality Raman spectra were recorded from negative and high grade (HG) cytology samples with no blood contamination and with heavy blood contamination. Good classification between negative and HG cytology could be achieved for samples with no blood contamination (sensitivity 92%, specificity 93%) and heavy blood contamination (sensitivity 89%, specificity 88%) with poorer classification when samples were combined (sensitivity 82%, specificity 87%). This study demonstrates for the first time the improved potential of Raman spectroscopy for analysis of ThinPrep specimens regardless of blood contamination.

Full Text Available Antiretrovirals have substantial promise for HIV-1 prevention, either as antiretroviral treatment (ART for HIV-1-infected persons to reduce infectiousness, or as pre-exposure prophylaxis (PrEP for HIV-1-uninfected persons to reduce the possibility of infection with HIV-1. HIV-1 serodiscordant couples in long-term partnerships (one member is infected and the other is uninfected are a priority for prevention interventions. Earlier ART and PrEP might both reduce HIV-1 transmission in this group, but the merits and synergies of these different approaches have not been analyzed.We constructed a mathematical model to examine the impact and cost-effectiveness of different strategies, including earlier initiation of ART and/or PrEP, for HIV-1 prevention for serodiscordant couples. Although the cost of PrEP is high, the cost per infection averted is significantly offset by future savings in lifelong treatment, especially among couples with multiple partners, low condom use, and a high risk of transmission. In some situations, highly effective PrEP could be cost-saving overall. To keep couples alive and without a new infection, providing PrEP to the uninfected partner could be at least as cost-effective as initiating ART earlier in the infected partner, if the annual cost of PrEP is 70% effective.Strategic use of PrEP and ART could substantially and cost-effectively reduce HIV-1 transmission in HIV-1 serodiscordant couples. New and forthcoming data on the efficacy of PrEP, the cost of delivery of ART and PrEP, and couples behaviours and preferences will be critical for optimizing the use of antiretrovirals for HIV-1 prevention.

This paper used qualitative methods to explore experiences of men who have sex with men and female sex workers in Nairobi and Mtwapa, Kenya, who used oral pre-exposure prophylaxis (PrEP) for HIV prevention as part of a four-month trial of safety, acceptability and adherence. Fifty-one of 72 volunteers who took part in a randomized, placebo-controlled, blinded trial that compared daily and intermittent dosage of PrEP underwent qualitative assessments after completing the trial. Analyses identified three themes: (i) acceptability of PrEP was high, i.e. side effects were experienced early in the study but diminished over time, however characteristics of pills could improve comfort and use; (ii) social impacts such as stigma, rumors, and relationship difficulties due to being perceived as HIV positive were prevalent; (iii) adherence was challenged by complexities of daily life, in particular post-coital dosing adherence suffered from alcohol use around time of sex, mobile populations, and transactional sex work. These themes resonated across dosing regimens and gender, and while most participants favored the intermittent dosing schedule, those in the intermittent group noted particular challenges in adhering to the post-coital dose. Culturally appropriate and consistent counseling addressing these issues may be critical for PrEP effectiveness.

Integrated Curriculum and Subject-based Curriculum: Achievement and Attitudes

Science.gov (United States)

Casady, Victoria

The research conducted for this mixed-method study, qualitative and quantitative, analyzed the results of an academic year-long study to determine whether the use of an integrated fourth grade curriculum would benefit student achievement in the areas of English language arts, social studies, and science more than a subject-based traditional curriculum. The research was conducted based on the international, national, and state test scores, which show a slowing or lack of growth. Through pre- and post-assessments, student questionnaires, and administrative interviews, the researcher analyzed the phenomenological experiences of the students to determine if the integrated curriculum was a beneficial restructuring of the curriculum. The research questions for this study focused on the achievement and attitudes of the students in the study and whether the curriculum they were taught impacted their achievement and attitudes over the course of one school year. The curricula for the study were organized to cover the current standards, where the integrated curriculum focused on connections between subject areas to help students make connections to what they are learning and the world beyond the classroom. The findings of this study indicated that utilizing the integrated curriculum could increase achievement as well as students' attitudes toward specific content areas. The ANOVA analysis for English language arts was not determined to be significant; although, greater growth in the students from the integrated curriculum setting was recorded. The ANOVA for social studies (0.05) and the paired t-tests (0.001) for science both determined significant positive differences. The qualitative analysis led to the discovery that the experiences of the students from the integrated curriculum setting were more positive. The evaluation of the data from this study led the researcher to determine that the integrated curriculum was a worthwhile endeavor to increase achievement and attitudes

2009-06-01

Full Text Available Abstract Background Standardizing the experiences of medical students in a community preceptorship where clinical sites vary by geography and discipline can be challenging. Computer-assisted learning is prevalent in medical education and can help standardize experiences, but often is not used to its fullest advantage. A blended learning curriculum combining web-based modules with face-to-face learning can ensure students obtain core curricular principles. Methods This course was developed and used at The Case Western Reserve University School of Medicine and its associated preceptorship sites in the greater Cleveland area. Leaders of a two-year elective continuity experience at the Case Western Reserve School of Medicine used adult learning principles to develop four interactive online modules presenting basics of office practice, difficult patient interviews, common primary care diagnoses, and disease prevention. They can be viewed at http://casemed.case.edu/cpcp/curriculum. Students completed surveys rating the content and technical performance of each module and completed a Generalist OSCE exam at the end of the course. Results Participating students rated all aspects of the course highly; particularly those related to charting and direct patient care. Additionally, they scored very well on the Generalist OSCE exam. Conclusion Students found the web-based modules to be valuable and to enhance their clinical learning. The blended learning model is a useful tool in designing web-based curriculum for enhancing the clinical curriculum of medical students.

The cost and impact of scaling up pre-exposure prophylaxis for HIV prevention: a systematic review of cost-effectiveness modelling studies.

Directory of Open Access Journals (Sweden)

Gabriela B Gomez

Full Text Available Cost-effectiveness studies inform resource allocation, strategy, and policy development. However, due to their complexity, dependence on assumptions made, and inherent uncertainty, synthesising, and generalising the results can be difficult. We assess cost-effectiveness models evaluating expected health gains and costs of HIV pre-exposure prophylaxis (PrEP interventions.We conducted a systematic review comparing epidemiological and economic assumptions of cost-effectiveness studies using various modelling approaches. The following databases were searched (until January 2013: PubMed/Medline, ISI Web of Knowledge, Centre for Reviews and Dissemination databases, EconLIT, and region-specific databases. We included modelling studies reporting both cost and expected impact of a PrEP roll-out. We explored five issues: prioritisation strategies, adherence, behaviour change, toxicity, and resistance. Of 961 studies retrieved, 13 were included. Studies modelled populations (heterosexual couples, men who have sex with men, people who inject drugs in generalised and concentrated epidemics from Southern Africa (including South Africa, Ukraine, USA, and Peru. PrEP was found to have the potential to be a cost-effective addition to HIV prevention programmes in specific settings. The extent of the impact of PrEP depended upon assumptions made concerning cost, epidemic context, programme coverage, prioritisation strategies, and individual-level adherence. Delivery of PrEP to key populations at highest risk of HIV exposure appears the most cost-effective strategy. Limitations of this review include the partial geographical coverage, our inability to perform a meta-analysis, and the paucity of information available exploring trade-offs between early treatment and PrEP.Our review identifies the main considerations to address in assessing cost-effectiveness analyses of a PrEP intervention--cost, epidemic context, individual adherence level, PrEP programme coverage

Full Text Available Background: Weakness of curriculum development in nursing education results in lack of professional skills in graduates. This study was done on master's students in nursing to evaluate challenges of neonatal intensive care nursing curriculum based on context, input, process, and product (CIPP evaluation model. Materials and Methods: This study was conducted with qualitative approach, which was completed according to the CIPP evaluation model. The study was conducted from May 2014 to April 2015. The research community included neonatal intensive care nursing master's students, the graduates, faculty members, neonatologists, nurses working in neonatal intensive care unit (NICU, and mothers of infants who were hospitalized in such wards. Purposeful sampling was applied. Results: The data analysis showed that there were two main categories: “inappropriate infrastructure” and “unknown duties,” which influenced the context formation of NICU master's curriculum. The input was formed by five categories, including “biomedical approach,” “incomprehensive curriculum,” “lack of professional NICU nursing mentors,” “inappropriate admission process of NICU students,” and “lack of NICU skill labs.” Three categories were extracted in the process, including “more emphasize on theoretical education,” “the overlap of credits with each other and the inconsistency among the mentors,” and “ineffective assessment.” Finally, five categories were extracted in the product, including “preferring routine work instead of professional job,” “tendency to leave the job,” “clinical incompetency of graduates,” “the conflict between graduates and nursing staff expectations,” and “dissatisfaction of graduates.” Conclusions: Some changes are needed in NICU master's curriculum by considering the nursing experts' comments and evaluating the consequences of such program by them.

To use and review a conceptual model of process evaluation and to examine the implementation of a nutrition education curriculum, Choice, Control & Change, designed to promote dietary and physical activity behaviors that reduce obesity risk. A process evaluation study based on a systematic conceptual model. Five middle schools in New York City. Five hundred sixty-two students in 20 classes and their science teachers (n = 8). Based on the model, teacher professional development, teacher implementation, and student reception were evaluated. Also measured were teacher characteristics, teachers' curriculum evaluation, and satisfaction with teaching the curriculum. Descriptive statistics and Spearman ρ correlation for quantitative analysis and content analysis for qualitative data were used. Mean score of the teacher professional development evaluation was 4.75 on a 5-point scale. Average teacher implementation rate was 73%, and the student reception rate was 69%. Ongoing teacher support was highly valued by teachers. Teacher satisfaction with teaching the curriculum was highly correlated with student satisfaction (P Teacher perception of amount of student work was negatively correlated with implementation and with student satisfaction (P < .05). Use of a systematic conceptual model and comprehensive process measures improves understanding of the implementation process and helps educators to better implement interventions as designed.

Effective professional development offers opportunities for teachers to reflect on their practices, modify and implement changes in the classroom, and eventually impact students' learning. However, professional development must be evaluated to determine whether the desired results are actually occurring in the classroom. The Program for Research and Evaluation for Public Schools, Inc. (PREPS) created a Biology I Workshop series to assist school districts in Mississippi in aligning curriculum, instruction, and assessment that will ultimately improve student achievement in the classroom and performance on the current high-stakes test. This study evaluated the PREPS Biology I Subject Area workshops by using Thomas Guskey's evaluation model as a guide for the process. This study used a mixed-method design and collected data from three primary sources: the PREPS Final Evaluation Form completed at the conclusion of workshops, a questionnaire created by the researcher, and interviews with six-case study teacher participants selected from the results of the questionnaire. According to the ratings and comments written on the two instruments and supporting evidence from the case-study teachers, the participants of the Biology I workshop found the workshops to be effective for all five levels of Guskey's evaluation model. The content was rated effective because the workshop materials were aligned to the curriculum frameworks and were focused on using student learning to improve student achievement. Working through the activities rather than simply being told about them and having a successful classroom biology teacher as a presenter were the factors that contributed to the increase in the participants' knowledge and skills. Organizational results indicate that the workshop was effective in that the goals of the workshop series aligned with the schools' mission and goals for student learning. Several issues, such as financial support, time for collaboration with peers, and

In this paper, we begin by providing an overview of the Educator Pathway Project (EPP), an education infrastructure that was developed in response to emerging critical nursing workplace issues, and the related demand for enhanced workplace education. We then describe the EPP competency-based curriculum designed to prepare nurses as preceptors, mentors, and educators to lead learning with diverse learner groups. This competency-based curriculum was developed through a collaboration of nurse leaders across practice, academic, and union sectors and drew from a widely embraced curriculum development model (Iwasiw, Goldenberg, & Andrusyzyn, 2005). The goal of the curriculum was to prepare nurses through a four-level career pathway model that contextualized practice and education theory to various education-related roles and levels of experience within the practice setting. Over 1,100 nurses participated in this innovative intersectoral nursing initiative.

No universal solution, based on an approved pedagogical approach, exists to parametrically describe, effectively manage, and clearly visualize a higher education institution's curriculum, including tools for unveiling relationships inside curricular datasets. We aim to solve the issue of medical curriculum mapping to improve understanding of the complex structure and content of medical education programs. Our effort is based on the long-term development and implementation of an original web-based platform, which supports an outcomes-based approach to medical and healthcare education and is suitable for repeated updates and adoption to curriculum innovations. We adopted data exploration and visualization approaches in the context of medical curriculum innovations in higher education institutions domain. We have developed a robust platform, covering detailed formal metadata specifications down to the level of learning units, interconnections, and learning outcomes, in accordance with Bloom's taxonomy and direct links to a particular biomedical nomenclature. Furthermore, we used selected modeling techniques and data mining methods to generate academic analytics reports from medical curriculum mapping datasets. We present a solution that allows users to effectively optimize a curriculum structure that is described with appropriate metadata, such as course attributes, learning units and outcomes, a standardized vocabulary nomenclature, and a tree structure of essential terms. We present a case study implementation that includes effective support for curriculum reengineering efforts of academics through a comprehensive overview of the General Medicine study program. Moreover, we introduce deep content analysis of a dataset that was captured with the use of the curriculum mapping platform; this may assist in detecting any potentially problematic areas, and hence it may help to construct a comprehensive overview for the subsequent global in-depth medical curriculum

The production of simulated samples for physics analysis at LHC represents a noticeable organization challenge, because it requires the management of several thousands different workflows. The submission of a workflow to the grid based computing infrastructure starts with the definition of the general characteristics of a given set of coherent samples (called a ‘campaign'), up to the definition of the physics settings to be used for each sample corresponding to a specific process to be simulated, both at hard event generation and detector simulation level. In order to have an organized control of the of the definition of the large number of MC samples needed by CMS, a dedicated management tool, called PREP, has been built. Its basic component is a database storing all the relevant information about the sample and the actions implied by the workflow definition, approval and production. A web based interface allows the database to be used from experts involved in production to trigger all the different actions needed, as well as by normal physicists involved in analyses to retrieve the relevant information. The tool is integrated through a set of dedicated APIs with the production agent and information storage utilities of CMS.

The goal was achieved through research and development method, is divided into three main stages. First, applied need analysis as the introduction. Second, developed the curriculum model. Third, tested the curriculum model in order to explore the curriculum effectiveness in improving the competency for mitigation measurement related to geological hazard. This study showed that the training curriculum model, which is developed based on the result of need analysis, is effective to improve the participant’s competency. The result of pre-post test shows that the improvement of the participant’s cognitive aspect.  The significant improvement is identified in the training competency showing the effectiveness of Test II in improving the participant’s practical competency to carry out the training. Some factors that support the training curriculum model development related to community-based Landslides management are: (a the public servant’s competency for geological hazard mitigation; (b the motivation of the community who becomes the volunteer; and (c support from the decision maker. On the other hand, the inhibitors are the lack of competency for training related to geological field, the lack of educational background and knowledge of geology and landslides, and the lack of time.

Testing Times for the Implementation of Curriculum Change

Full Text Available School curriculum change processes have traditionally been managed internally. However, in Queensland, Australia, as a response to the current high-stakes accountability regime, more and more principals are outsourcing this work to external change agents (ECAs. In 2009, one of the authors (a university lecturer and ECA developed a curriculum change model (the Controlled Rapid Approach to Curriculum Change [CRACC], specifically outlining the involvement of an ECA in the initiation phase of a school’s curriculum change process. The purpose of this article is to extend the CRACC model by unpacking the implementation phase, drawing on data from a pilot study of a single school. Interview responses revealed that during the implementation phase, teachers wanted to be kept informed of the wider educational context, use data to constantly track students, relate pedagogical practices to testing practices, share information between departments and professional levels, and own whole school performance. It is suggested that the findings would be transferable to other school settings and internal leadership of curriculum change. The article also strikes a chord of concern: Do the responses from teachers operating under thecurrent accountability regime live their professional lives within this corporate and globalized ideology whether they want to or not?

Full Text Available This paper reviews the concept of hidden curriculum in the sociological theories and wants to explain sociological aspects of formation of hidden curriculum. The main question concentrates on the theoretical approaches in which hidden curriculum is explained sociologically.For this purpose it was applied qualitative research methodology. The relevant data include various sociological concepts and theories of hidden curriculum collected by the documentary method. The study showed a set of rules, procedures, relationships and social structure of education have decisive role in the formation of hidden curriculum. A hidden curriculum reinforces by existed inequalities among learners (based on their social classes or statues. There is, in fact, a balance between the learner's "knowledge receptions" with their "inequality proportion".The hidden curriculum studies from different major sociological theories such as Functionalism, Marxism and critical theory, Symbolic internationalism and Feminism. According to the functionalist perspective a hidden curriculum has a social function because it transmits social values. Marxists and critical thinkers correlate between hidden curriculum and the totality of social structure. They depicts that curriculum prepares learners for the exploitation in the work markets. Symbolic internationalism rejects absolute hegemony of hidden curriculum on education and looks to the socialization as a result of interaction between learner and instructor. Feminism theory also considers hidden curriculum as a vehicle which legitimates gender stereotypes.

In the UK, HIV incidence among men who have sex with men (MSM) has remained high for several years, despite widespread use of antiretroviral therapy and high rates of virological suppression. Pre-exposure prophylaxis (PrEP) has been shown to be highly effective in preventing further infections in MSM, but its cost-effectiveness is uncertain. In this modelling study and economic evaluation, we calibrated a dynamic, individual-based stochastic model, the HIV Synthesis Model, to multiple data sources (surveillance data provided by Public Health England and data from a large, nationally representative survey, Natsal-3) on HIV among MSM in the UK. We did a probabilistic sensitivity analysis (sampling 22 key parameters) along with a range of univariate sensitivity analyses to evaluate the introduction of a PrEP programme with sexual event-based use of emtricitabine and tenofovir for MSM who had condomless anal sexual intercourse in the previous 3 months, a negative HIV test at baseline, and a negative HIV test in the preceding year. The main model outcomes were the number of HIV infections, quality-adjusted life-years (QALYs), and costs. Introduction of such a PrEP programme, with around 4000 MSM initiated on PrEP by the end of the first year and almost 40 000 by the end of the 15th year, would result in a total cost saving (£1·0 billion discounted), avert 25% of HIV infections (42% of which would be directly because of PrEP), and lead to a gain of 40 000 discounted QALYs over an 80-year time horizon. This result was particularly sensitive to the time horizon chosen, the cost of antiretroviral drugs (for treatment and PrEP), and the underlying trend in condomless sex. This analysis suggests that the introduction of a PrEP programme for MSM in the UK is cost-effective and possibly cost-saving in the long term. A reduction in the cost of antiretroviral drugs (including the drugs used for PrEP) would substantially shorten the time for cost savings to be realised

Wainwright, P; Jones, P G

2000-01-01

It is widely acknowledged that the education and training of nurses in information management and technology is problematic. Drawing from recent research this paper presents a theoretical framework within which the nature of the problems faced by nurses in the use of information may be analyzed. This framework, based on the critical social theory of Habermas, also provides a model for the informatics curriculum. The advantages of problem based learning and multi-media web-based technologies for the delivery of learning materials within this area are also discussed.

Strong relationship between oral dose and tenofovir hair levels in a randomized trial: hair as a potential adherence measure for pre-exposure prophylaxis (PrEP.

Directory of Open Access Journals (Sweden)

Albert Y Liu

Full Text Available Pre-exposure prophylaxis (PrEP trials using tenofovir-based regimens have demonstrated that high levels of adherence are required to evaluate efficacy; the incorporation of objective biomarkers of adherence in trial design has been essential to interpretation, given the inaccuracy of self-report. Antiretroviral measurements in scalp hair have been useful as a marker of long-term exposure in the HIV treatment setting, and hair samples are relatively easy and inexpensive to collect, transport, and store for analysis. To evaluate the relationship between dose and tenofovir concentrations in hair, we examined the dose proportionality of tenofovir in hair in healthy, HIV-uninfected adults.A phase I, crossover pharmacokinetic study was performed in 24 HIV-negative adults receiving directly-observed oral tenofovir tablets administered 2, 4, and 7 doses/week for 6 weeks, with a ≥3-week break between periods. Small samples of hair were collected after each six-week period and analyzed for tenofovir concentrations. Geometric-mean-ratios compared levels between each pair of dosing conditions. Intensive plasma pharmacokinetic studies were performed during the daily-dosing period to calculate areas-under-the-time-concentration curves (AUCs.Over 90% of doses were observed per protocol. Median tenofovir concentrations in hair increased monotonically with dose. A log-linear relationship was seen between dose and hair levels, with an estimated 76% (95% CI 60-93% increase in hair level per 2-fold dose increase. Tenofovir plasma AUCs modestly predicted drug concentrations in hair.This study found a strong linear relationship between frequency of dosing and tenofovir levels in scalp hair. The analysis of quantitative drug levels in hair has the potential to improve adherence measurement in the PrEP field and may be helpful in determining exposure thresholds for protection and explaining failures in PrEP trials. Hair measures for adherence monitoring may also

Pre-operative oral antibiotics administered the day prior to elective colectomy have been shown to decrease the incidence of surgical site infections (SSI) if a mechanical bowel prep (MBP) is used. Recently, the role for mechanical bowel prep has been challenged as being unnecessary and potentially harmful. We hypothesize that if MBP is omitted, oral antibiotics do not alter the incidence of SSI following colectomy. We selected patients who underwent an elective segmental colectomy from the 2012 and 2013 National Surgical Quality Improvement Program colectomy procedure targeted database. Indications for surgery included colon cancer, diverticulitis, inflammatory bowel disease, or benign polyp. Patients who received mechanical bowel prep were excluded. The primary outcome measured was surgical site infection, defined as the presence of superficial, deep or, organ space infection within 30 d from surgery. A total of 6,399 patients underwent elective segmental colectomy without MBP. The incidence of SSI differed substantially between patients who received oral antibiotics, versus those who did not (9.7% vs. 13.7%, p=0.01). Multivariate analysis indicated that age, smoking status, operative time, perioperative transfusions, oral antibiotics, and surgical approach were associated with post-operative SSI. When controlling for confounding factors, the use of pre-operative oral antibiotics decreased the incidence of surgical site infection (odds ratio=0.66, 95% confidence interval=0.48-0.90, p=0.01). Even in the absence of mechanical bowel prep, pre-operative oral antibiotics appear to reduce the incidence of surgical site infection following elective colectomy.

Houston prefreshman enrichment program (Houston PREP). Final report, June 10, 1996--August 1, 1996

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.

2016-08-12

The "flipped classroom" teaching model practiced in the teaching of Theories of Different Schools of Acupuncture and Moxibustion curriculum was introduced. Firstly, the roles and responsibilities of teachers were clarified, indicating teachers provided examples and lectures, and a comprehensive assessment system was established. Secondly, the "flipped classroom" teaching model was split into online learning, classroom learning and offline learning. Online learning aimed at forming a study report by a wide search of relevant information, which was submitted to teachers for review and assessment. Classroom learning was designed to communicate study ideas among students and teachers. Offline learning was intended to revise and improve the study report and refined learning methods. Lastly, the teaching practice effects of "flip classroom" were evaluated by comprehensive rating and questionnaire assessment, which assessed the overall performance of students and overall levels of paper; the learning ability was enhanced, and the interest and motivation of learning were also improved. Therefore, "flipped classroom" teaching mode was suitable for the curriculum of Theories of Different Schools of Acupuncture and Moxibustion , and could be recommended into the teaching practice of related curriculum of acupuncture and tuina.

Evaluation of how a curriculum change in nurse education was managed through the application of a business change management model: A qualitative case study.

Curriculum changes are a regular feature of nurse education, yet little is known about how such changes are managed. Research in this arena is yet to emerge. Evaluation of how a curriculum change in nurse education was managed through the application of a business change management model. A qualitative case study: the single case was the new curriculum, the Primary Care Pathway. One executive, three senior managers, two academics and nineteen students participated in this study in one faculty of health and social care in a higher education institution. The findings suggest that leadership was pivotal to the inception of the programme and guiding teams managed the change and did not take on a leadership role. The vision for the change and efforts to communicate it did not reach the frontline. Whilst empowerment was high amongst stakeholders and students, academics felt dis-empowered. Short-term wins were not significant in keeping up the momentum of change. The credibility of the change was under challenge and the concept of the new programme was not yet embedded in academia. Differences between the strategic and operational part of the organisation surfaced with many challenges occurring at the implementation stage. The business change model used was valuable, but was found to not be applicable during curriculum changes in nurse education. A new change model emerged, and a tool was developed alongside to aid future curriculum changes. Copyright © 2015 Elsevier Ltd. All rights reserved.

The “unknown” Greek Paleoenvironment: Curriculum Proposals through an Infusion Model for Elementary School, Using Ammonite Fossils

Directory of Open Access Journals (Sweden)

Stiliani FRAGOULI

2017-06-01

Full Text Available In this study we introduce an infusion model to “inject” ammonites and ammonite fossils in current subjects of Greek primary curriculum. Paleontology and mainly fossils attract more and more elementary students and teachers, yet in Greece this trend is solely about dinosaurs, despite the fact that the most common Greek fossils are not dinosaurs, but ammonites. Ammonites can be found in large population and diversity inside Greek rocks, as these rocks were part of Tethys΄ seafloor at their geological time. Apart from the informal sources of education, these science topics are excluded from elementary national curriculum, and leave the regional paleoenvironment and geological history practically “unknown” to students. Data collected through a pre-test study, in 558 students of 4th, 5th, and 6th grade confirmed the above belief. A post-test at the original sample, using an open ended questionnaire and students’ drawings, evaluated positively the infusion teaching model, whose core were the ammonite fossils.

The main purpose of this study is to fill a substantial knowledge gap regarding reaching a uniform group decision in English curriculum design and planning. A comprehensive content-based course criterion model extracted from existing literature and expert opinions was developed. Analytical hierarchy process (AHP) was used to identify the relative importance of course criteria for the purpose of tailoring an optimal one-week immersion English as a second language (ESL) curriculum for elementary school students in a suburban county of Taiwan. The hierarchy model and AHP analysis utilized in the present study will be useful for resolving several important multi-criteria decision-making issues in planning and evaluating ESL programs. This study also offers valuable insights and provides a basis for further research in customizing ESL curriculum models for different student populations with distinct learning needs, goals, and socioeconomic backgrounds.

HIV Treatment and Prevention: A Simple Model to Determine Optimal Investment.

Juusola, Jessie L; Brandeau, Margaret L

2016-04-01

To create a simple model to help public health decision makers determine how to best invest limited resources in HIV treatment scale-up and prevention. A linear model was developed for determining the optimal mix of investment in HIV treatment and prevention, given a fixed budget. The model incorporates estimates of secondary health benefits accruing from HIV treatment and prevention and allows for diseconomies of scale in program costs and subadditive benefits from concurrent program implementation. Data sources were published literature. The target population was individuals infected with HIV or at risk of acquiring it. Illustrative examples of interventions include preexposure prophylaxis (PrEP), community-based education (CBE), and antiretroviral therapy (ART) for men who have sex with men (MSM) in the US. Outcome measures were incremental cost, quality-adjusted life-years gained, and HIV infections averted. Base case analysis indicated that it is optimal to invest in ART before PrEP and to invest in CBE before scaling up ART. Diseconomies of scale reduced the optimal investment level. Subadditivity of benefits did not affect the optimal allocation for relatively low implementation levels. The sensitivity analysis indicated that investment in ART before PrEP was optimal in all scenarios tested. Investment in ART before CBE became optimal when CBE reduced risky behavior by 4% or less. Limitations of the study are that dynamic effects are approximated with a static model. Our model provides a simple yet accurate means of determining optimal investment in HIV prevention and treatment. For MSM in the US, HIV control funds should be prioritized on inexpensive, effective programs like CBE, then on ART scale-up, with only minimal investment in PrEP. © The Author(s) 2015.

PREP-45, Input Preparation for CITATION-2

International Nuclear Information System (INIS)

Ramalho Carlos, C.A.

1995-01-01

1 - Description of program or function: A Fortran program has been created, which saves much effort in preparing sections 004 (intervals in the coordinates) and 005 (zone numbers) of the input data file for the multigroup theory code CITATION (version CITATION-2, NESC0387/09), particularly when a thin complicated mesh is used. 2 - Method of solution: A domain is defined for CITATION calculations through specifying its sub-domains (e.g. graphite, lead, beryllium, water and fuel sub-domains) in a compact and simple way. An independent and previous geometrical specification is made of the various types of elements which are envisaged to constitute the contents of the reactor core grid positions. Then the load table for the configuration is input and scanned throughout, thus enabling the geometric mesh description to be produced (section 004). Also the zone placement (section 005) is achieved by means of element description subroutines for the different types of element (which may require appropriate but simple changes in the actual cases). The output of PREP45 is directly obtained in a format which is compatible with CITATION-2 input. 3 - Restrictions on the complexity of the problem: Only rectangular two-dimensional Cartesian coordinates are considered. A maximum of 12 sub-domains in the x direction (18 in the y direction) and up to 8 distinct element types are considered in this version. Other limitations exist which can nevertheless be overcome with simple changes in the source program

"It takes a lot of courage to release the familiar and seemingly secure, to embrace the new. But there is no real security in what is no longer meaningful. There is more security in the adventurous and exciting, for in movement there is life, and in change there is power." Alan Cohen (Used by permission. All rights reserved. For more information on Alan Cohen's books and programs, see (www.alancohen.com.) With the support of the East Tennessee State University (ETSU) administration and a grant from Howard Hughes Medical Institute, the departments of Biological Sciences, Mathematics and Statistics, and Curriculum and Instruction have developed a biology-math integrated curriculum. An interdisciplinary faculty team, charged with teaching the 18 curriculum modules, designed this three-semester curriculum, known as SYMBIOSIS. This curriculum was piloted to two student cohorts during the developmental stage. The positive feedback and assessment results of this project have given us the foundation to implement the SYMBIOSIS curriculum as a replacement for the standard biology majors curriculum at the introductory level. This article addresses the history and development of the curriculum, previous assessment results and current assessment protocol, and the future of ETSU's approach to implementing the SYMBIOSIS curriculum.

2014-03-01

Introducing critical thinking and evidence-based dentistry (EBD) content into an established dental curriculum can be a difficult and challenging process. Over the past three years, the University of Iowa College of Dentistry has developed and implemented a progressive four-year integrated critical thinking and EBD curriculum. The objective of this article is to describe the development and implementation process to make it available as a model for other dental schools contemplating introduction of critical thinking and EBD into their curricula. The newly designed curriculum built upon an existing problem-based learning foundation, which introduces critical thinking and the scientific literature in the D1 year, in order to expose students to the rationale and resources for practicing EBD in the D2 and D3 years and provide opportunities to practice critical thinking and apply the EBD five-step process in the D2, D3, and D4 years. All curricular content is online, and D3 and D4 EBD activities are integrated within existing clinical responsibilities. The curricular content, student resources, and student activities are described.

Thematic curriculum approach

Directory of Open Access Journals (Sweden)

Šefer Jasmina P.

2003-01-01

Full Text Available Thematic curriculum combines disciplines and media. The process is problem-oriented and the scenario most often follows the logic of exploring or storytelling. Those two approaches to teaching are appropriate because they fit into interdisciplinary and creative open-ended problem solving through play, as insisted upon by thematic curriculum. The matrix, where seven types of abilities intersect with five types of problems according to their degree of openness, defines well the outcomes of teaching. However, it did not prove to be suitable for planning the majority of activities in thematic curriculum, for it follows with difficulty the process of exploring or storytelling i.e. it disrupts the subject matter coherence of thematic curriculum. Therefore, it is suggested that matrix should be used for disciplinary curriculum planning but for that of thematic curriculum only in exclusive cases. The matrix should be used primarily as a framework for evaluating the distribution of various types of abilities and problem situations in teaching. The logic of diverse approaches to teaching reflects itself in the manner of planning and organizing the teaching process. Conceptual, visual-graphic, structural and other aids employed during educational process planning should suit the nature of the approach chosen. On the basis of qualitative investigations of educational process, in the present paper considerations are given to various approaches to teaching development of various drafts for the planning of teaching, and recognition of the logic of storytelling and exploring in thematic curriculum.

Shi, Jianhua; Lei, Bing; Liu, Wei; Yao, Tianfu; Jiang, Wenjie

2017-08-01

"Flipped Classroom" is one of the most popular teaching models, and has been applied in more and more curriculums. It is totally different from the traditional teaching model. In the "Flipped Classroom" model, the students should watch the teaching video afterschool, and in the classroom only the discussion is proceeded to improve the students' comprehension. In this presentation, "Flipped Classroom" was studied and practiced in opto-electronic technology curriculum; its effect was analyzed by comparing it with the traditional teaching model. Based on extensive and deep investigation, the phylogeny, the characters and the important processes of "Flipped Classroom" are studied. The differences between the "Flipped Classroom" and the traditional teaching model are demonstrated. Then "Flipped Classroom" was practiced in opto-electronic technology curriculum. In order to obtain high effectiveness, a lot of teaching resources were prepared, such as the high-quality teaching video, the animations and the virtual experiments, the questions that the students should finish before and discussed in the class, etc. At last, the teaching effect was evaluated through analyzing the result of the examination and the students' surveys.

Development of Whole Slide Imaging on Smartphones and Evaluation With ThinPrep Cytology Test Samples: Follow-Up Study

Science.gov (United States)

Ma, Shuoxin; Yu, Hong; Jin, Yu-Biao; Zheng, Jun

2018-01-01

Background The smartphone-based whole slide imaging (WSI) system represents a low-cost and effective alternative to automatic scanners for telepathology. In a previous study, the development of one such solution, named scalable whole slide imaging (sWSI), was presented and analyzed. A clinical evaluation of its iOS version with 100 frozen section samples verified the diagnosis-readiness of the produced virtual slides. Objective The first aim of this study was to delve into the quantifying issues encountered in the development of an Android version. It should also provide insights into future high-resolution real-time feedback medical imaging apps on Android and invoke the awareness of smartphone manufacturers for collaboration. The second aim of this study was to further verify the clinical value of sWSI with cytology samples. This type is different from the frozen section samples in that they require finer detail on the cellular level. Methods During sWSI development on Android, it was discovered that many models do not support uncompressed camera pixel data with sufficient resolution and full field of view. The proportion of models supporting the optimal format was estimated in a test on 200 mainstream Android models. Other factors, including slower processing speed and camera preview freezing, also led to inferior performance of sWSI on Android compared with the iOS version. The processing speed was mostly determined by the central processing unit frequency in theory, and the relationship was investigated in the 200-model simulation experiment with physical devices. The camera preview freezing was caused by the lag between triggering photo capture and resuming preview. In the clinical evaluation, 100 ThinPrep cytology test samples covering 6 diseases were scanned with sWSI and compared against the ground truth of optical microscopy. Results Among the tested Android models, only 3.0% (6/200) provided an optimal data format, meeting all criteria of quality and

A Model Curriculum for an Emergency Medical Services (EMS Rotation for Emergency Medicine Residents

Directory of Open Access Journals (Sweden)

Michael Mancera

2018-01-01

Full Text Available Audience: This EMS curriculum is designed for Emergency Medicine residents at all levels of training. Introduction: Emergency Medicine (EM physicians have routine interaction with Emergency Medical Services (EMS in their clinical practice. Additionally, the American College of Graduate Medical Education (ACGME mandates that all Emergency Medicine resident physicians receive specific training in the area of EMS.1 Historically, EMS training for EM residents has been conducted in the absence of a standardized didactic curriculum. Despite advancements in the area of prehospital training, there remains wide inconsistency in EMS training experiences among EM residency training programs.2 To our knowledge a standardized and reproducible EMS curriculum for EM residents does not exist. Objectives: The aim of this curriculum is to provide a robust learning experience for EM residents around prehospital care and EMS that fulfills the ACGME requirements and which can be easily replicated and implemented in a variety of EM residency training programs. Method: The educational strategies used in this curriculum include didactics, asynchronous learning through online modules and a focused reading list, experiential learning through ride-alongs, structured small group discussion, supervised medical command shifts, and mentored practice in organizing and delivering didactics to EMS providers.

There is no comprehensive simulation-enhanced training curriculum to address cognitive, psychomotor, and nontechnical skills for an advanced minimally invasive procedure. 1) To develop and provide evidence of validity for a comprehensive simulation-enhanced training (SET) curriculum for an advanced minimally invasive procedure; (2) to demonstrate transfer of acquired psychomotor skills from a simulation laboratory to live porcine model; and (3) to compare training outcomes of SET curriculum group and chief resident group. University. This prospective single-blinded, randomized, controlled trial allocated 20 intermediate-level surgery residents to receive either conventional training (control) or SET curriculum training (intervention). The SET curriculum consisted of cognitive, psychomotor, and nontechnical training modules. Psychomotor skills in a live anesthetized porcine model in the OR was the primary outcome. Knowledge of advanced minimally invasive and bariatric surgery and nontechnical skills in a simulated OR crisis scenario were the secondary outcomes. Residents in the SET curriculum group went on to perform a laparoscopic jejunojejunostomy in the OR. Cognitive, psychomotor, and nontechnical skills of SET curriculum group were also compared to a group of 12 chief surgery residents. SET curriculum group demonstrated superior psychomotor skills in a live porcine model (56 [47-62] versus 44 [38-53], Ppsychomotor skills in the live porcine model and in the OR in a human patient (56 [47-62] versus 63 [61-68]; P = .21). SET curriculum group demonstrated inferior knowledge (13 [11-15] versus 16 [14-16]; P<.05), equivalent psychomotor skill (63 [61-68] versus 68 [62-74]; P = .50), and superior nontechnical skills (41 [38-45] versus 34 [27-35], P<.01) compared with chief resident group. Completion of the SET curriculum resulted in superior training outcomes, compared with conventional surgery training. Implementation of the SET curriculum can standardize training

Mossop, Liz; Dennick, Reg; Hammond, Richard; Robbé, Iain

2013-02-01

Major influences on learning about medical professionalism come from the hidden curriculum. These influences can contribute positively or negatively towards the professional enculturation of clinical students. The fact that there is no validated method for identifying the components of the hidden curriculum poses problems for educators considering professionalism. The aim of this study was to analyse whether a cultural web, adapted from a business context, might assist in the identification of elements of the hidden curriculum at a UK veterinary school. A qualitative approach was used. Seven focus groups consisting of three staff groups and four student groups were organised. Questioning was framed using the cultural web, which is a model used by business owners to assess their environment and consider how it affects their employees and customers. The focus group discussions were recorded, transcribed and analysed thematically using a combination of a priori and emergent themes. The cultural web identified elements of the hidden curriculum for both students and staff. These included: core assumptions; routines; rituals; control systems; organisational factors; power structures, and symbols. Discussions occurred about how and where these issues may affect students' professional identity development. The cultural web framework functioned well to help participants identify elements of the hidden curriculum. These aspects aligned broadly with previously described factors such as role models and institutional slang. The influence of these issues on a student's development of a professional identity requires discussion amongst faculty staff, and could be used to develop learning opportunities for students. The framework is promising for the analysis of the hidden curriculum and could be developed as an instrument for implementation in other clinical teaching environments. © Blackwell Publishing Ltd 2013.

Generating alternatives in nursing: turning curriculum into a living process.

Science.gov (United States)

Perry, J; Moss, C

The transfer of nursing education into higher education institutions is challenging nurses to re-think educational structures and processes. Traditionally, nursing education has used objective curriculum models which tend to reinforce bureaucratic rather than professional values. Critics suggest that these models, by their failure to incorporate social, political and cultural realities, contribute to theory-practice dichotomies. This paper shares the intentions of Deakin University's School of Nursing in developing alternative approaches to curriculum design and to learning and practising nursing.

Auditing sex- and gender-based medicine (SGBM) content in medical school curriculum: a student scholar model.

Science.gov (United States)

Song, Michael M; Jones, Betsy G; Casanova, Robert A

2016-01-01

Sex- and gender-based medicine (SGBM) aims to (1) delineate and investigate sex- and gender-based differences in health, disease, and response to treatment and (2) apply that knowledge to clinical care to improve the health of both women and men. However, the integration of SGBM into medical school curricula is often haphazard and poorly defined; schools often do not know the current status of SGBM content in their curricula, even if they are committed to addressing gaps and improving SGBM delivery. Therefore, complete auditing and accounting of SGBM content in the existing medical school curriculum is necessary to determine the baseline status and prepare for successful integration of SGBM content into that curriculum. A review of course syllabi and lecture objectives as well as a targeted data analysis of the Curriculum Management and Information Tool (CurrMIT) were completed prior to a real-time curriculum audit. Subsequently, six "student scholars," three first-year and three second-year medical students, were recruited and trained to audit the first 2 years of the medical school curriculum for SGBM content, thus completing an audit for both of the pre-clinical years simultaneously. A qualitative analysis and a post-audit comparative analysis were completed to assess the level of SGBM instruction at our institution. The review of syllabi and the CurrMIT data analysis did not generate a meaningful catalogue of SGBM content in the curriculum; most of the content identified specifically targeted women's or men's health topics and not sex- or gender-based differences. The real-time student audit of the existing curriculum at Texas Tech revealed that most of the SGBM material was focused on the physiological/anatomical sex differences or gender differences in disease prevalence, with minimal coverage of sex- or gender-based differences in diagnosis, prognosis, treatment, and outcomes. The real-time student scholar audit was effective in identifying SGBM content in

An Infusion Model for Including Content on Elders with Chronic Illness in the Curriculum

2000-05-01

Full Text Available Older people with chronic mental illness (CMI are experiencing longer life expectancies that parallel those of the general population. Due to their experience of having CMI, these older adults present unique issues that affect service delivery and care provision. Content on this population is often omitted in the curriculum, which leaves students unprepared to practice with these clients. This article proposes an infusion model that can be used in baccalaureate or graduate foundation courses to increase exposure to elders with CMI.

Barsuk, Jeffrey H; Cohen, Elaine R; Wayne, Diane B; Siddall, Viva J; McGaghie, William C

2016-02-01

Curriculum development in medical education should follow a planned, systematic approach fitted to the needs and conditions of a local institutional environment and its learners. This article describes the development and maintenance of a simulation-based medical education curriculum on advanced cardiac life support skills and its transformation to a mastery learning program. Curriculum development used the Kern 6-step model involving problem identification and general needs assessment, targeted needs assessment, goals and objectives, educational strategies, implementation, and evaluation and feedback. Curriculum maintenance and enhancement and dissemination are also addressed. Transformation of the simulation-based medical education curriculum to a mastery learning program was accomplished after a 2-year phase-in trial. A series of studies spanning 11 years was performed to adjust the curriculum, improve checklist outcome measures, and evaluate curriculum effects as learning outcomes among internal medicine residents and improved patient care practices. We anticipate wide adoption of the mastery learning model for skill and knowledge acquisition and maintenance in medical education settings.

Lefurgy, Scott T; Mundorff, Emily C

2017-09-01

Here, we present a 13-week research-based biochemistry laboratory curriculum designed to provide the students with the experience of engaging in original research while introducing foundational biochemistry laboratory techniques. The laboratory experience has been developed around the directed evolution of an enzyme chosen by the instructor, with mutations designed by the students. Ideal enzymes for this curriculum are able to be structurally modeled, solubly expressed, and monitored for activity by UV/Vis spectroscopy, and an example curriculum for haloalkane dehalogenase is given. Unique to this curriculum is a successful implementation of saturation mutagenesis and high-throughput screening of enzyme function, along with bioinformatics analysis, homology modeling, structural analysis, protein expression and purification, polyacrylamide gel electrophoresis, UV/Vis spectroscopy, and enzyme kinetics. Each of these techniques is carried out using a novel student-designed mutant library or enzyme variant unique to the lab team and, importantly, not described previously in the literature. Use of a well-established set of protocols promotes student data quality. Publication may result from the original student-generated hypotheses and data, either from the class as a whole or individual students that continue their independent projects upon course completion. © 2017 by The International Union of Biochemistry and Molecular Biology, 45(5):437-448, 2017. © 2017 The International Union of Biochemistry and Molecular Biology.

Oral pre-exposure prophylaxis by anti-retrovirals raltegravir and maraviroc protects against HIV-1 vaginal transmission in a humanized mouse model.

Directory of Open Access Journals (Sweden)

C Preston Neff

Full Text Available Sexual HIV-1 transmission by vaginal route is the most predominant mode of viral transmission, resulting in millions of new infections every year. In the absence of an effective vaccine, there is an urgent need to develop other alternative methods of pre-exposure prophylaxis (PrEP. Many novel drugs that are currently approved for clinical use also show great potential to prevent viral sexual transmission when administered systemically. A small animal model that permits rapid preclinical evaluation of potential candidates for their systemic PrEP efficacy will greatly enhance progress in this area of investigation. We have previously shown that RAG-hu humanized mouse model permits HIV-1 mucosal transmission via both vaginal and rectal routes and displays CD4 T cell loss typical to that seen in the human. Thus far systemic PrEP studies have been primarily limited to RT inhibitors exemplified by tenofovir and emtricitabine. In these proof-of-concept studies we evaluated two new classes of clinically approved drugs with different modes of action namely, an integrase inhibitor raltegravir and a CCR5 inhibitor maraviroc as potential systemically administered chemo-prophylactics. Our results showed that oral administration of either of these drugs fully protects against vaginal HIV-1 challenge in the RAG-hu mouse model. Based on these results both these drugs show great promise for further development as orally administered PrEPs.

Developing a "clinical presentation" curriculum at the University of Calgary.

Science.gov (United States)

Mandin, H; Harasym, P; Eagle, C; Watanabe, M

1995-03-01

Currently, medical curricula are structured according to disciplines, body systems, or clinical problems. Beginning in 1988, the faculty of the University of Calgary Faculty of Medicine (U of C) carefully evaluated the advantages and disadvantages of each of these models in seeking to revise their school's curriculum. However, all three models fell short of a curricular structure based on current knowledge and principles of adult learning, clinical problem solving, community demands, and curriculum management. By 1991, the U of C had formulated a strategic plan for a revised curriculum structure based on the way patients present to physicians, and implementation of this plan has begun. In creating the new curriculum, 120 clinical presentations (e.g., "loss of consciousness/syncope") were defined and each was assigned to an individual or small group of faculty for development based on faculty expertise and interest. Terminal objectives (i.e., "what to do") were defined for each presentation to describe the appropriate clinical behaviors of a graduating physician. Experts developed schemes that outlined how they differentiated one cause (i.e., disease category) from another. The underlying enabling objectives (i.e., knowledge, skills, and attitudes) for reaching the terminal objectives for each clinical presentation were assigned as departmental responsibilities. A new administrative structure evolved in which there is a partnership between a centralized multidisciplinary curriculum committee and the departments. This new competency-based, clinical presentation curriculum is expected to significantly enhance students' development of clinical problem-solving skills and affirms the premise that prudent, continuous updating is essential for improving the quality of medical education.

Curriculum in radiology for residents: what, why, how, when, and where.

Science.gov (United States)

Collins, J

2000-02-01

Developing a curriculum in chest radiology should follow the same general principles that are used when developing a curriculum in any subspecialty area of radiology. A curriculum is more than a "list of topics" with which a resident should be familiar after 4 years of training. It includes objectives and goals, content, faculty, methods, and evaluation. Numerous resources are available for those who are charged with developing a curriculum in chest radiology. In addition to faculty members in the department, whose input during development can ensure successful implementation of the curriculum, organizations (i.e., ACR, APDR, STR) already have begun to develop "model" curricula. Attending the annual meeting of the Association of American Medical Colleges is a way to meet and hear from professionals who develop and oversee curriculum development at their medical schools, and another important resource available at some medical schools is the Office of Medical Education. The faculty within such offices are uniquely qualified to assist with curriculum and faculty development, especially for those areas in which radiology faculty traditionally are less experienced, such as development of valid and reliable assessment forms and construction of behaviorally based objectives.

Next Generation Sequencing (NGS) has significantly impacted human genetics, enabling a comprehensive characterization of the human genome as well as a better understanding of many genomic abnormalities. By delivering massive DNA sequences at unprecedented speed and cost, NGS promises to make personalized medicine a reality in the foreseeable future. To date, library construction with clinical samples has been a challenge, primarily due to the limited quantities of sample DNA available. Our objective here was to overcome this challenge by developing NEBNext® Ultra DNA Library Prep Kit, a fast library preparation method. Specifically, we streamlined the workflow utilizing novel NEBNext reagents and adaptors, including a new DNA polymerase that has been optimized to minimize GC bias. As a result of this work, we have developed a simple method for library construction from an amount of DNA as low as 5 ng, which can be used for both intact and fragmented DNA. Moreover, the workflow is compatible with multiple NGS platforms.

Sequence Matching Analysis for Curriculum Development

Full Text Available Many organizations apply information technologies to support their business processes. Using the information technologies, the actual events are recorded and utilized to conform with predefined model. Conformance checking is an approach to measure the fitness and appropriateness between process model and actual events. However, when there are multiple events with the same timestamp, the traditional approach unfit to result such measures. This study attempts to develop a sequence matching analysis. Considering conformance checking as the basis of this approach, this proposed approach utilizes the current control flow technique in process mining domain. A case study in the field of educational process has been conducted. This study also proposes a curriculum analysis framework to test the proposed approach. By considering the learning sequence of students, it results some measurements for curriculum development. Finally, the result of the proposed approach has been verified by relevant instructors for further development.

Humanism is a central tenant of professionalism, a required competency for all residency programs. Yet, few residencies have formal curriculum for teaching this critical aspect of medicine. Instead, professionalism and humanism are often taught informally through role-modeling. With increased burnout, faculty professionalism may suffer and may compromise resident role-modeling. The objective of this study was to design a pilot curriculum to foster humanism in among residents and assess its ability to do so. Two-phase exploratory sequential mixed methods study. Phase 1: a qualitative analysis of residents' narratives regarding challenges to humanistic behavior, and identified themes of compassion, fatigue, communication challenges, and work-life balance. Themes used as needs assessment to build curriculum. Phase 2: three sessions with themes taken from faculty development course. Participants and controls completed baseline and 60-day follow-up questionnaires assessing burnout, compassion, satisfaction, and ability to practice psychological medicine. Phase one included Obstetrics/Gynecology and internal medicine residents. Phase two included residents from the above programs, who attended at least 2/3 interactive sessions designed to address the themes identified above. Twelve participants began and ten completed curriculum (83%). The curriculum met course objectives and was well-received (4.8/5). Burnout decreased (-3.1 vs. 2.5, P = 0.048). A trend toward improved compassion (4.4 vs.-0.6, P = 0.096) for participants compared to controls was noted. A pilot humanism curriculum for residents was well-received. Participants showed decreased burnout and trended to improved compassion scores. Development and evaluation of an expanded curriculum would further explore feasibility and effectiveness of the intervention.

Explore-create-share study: An evaluation of teachers as curriculum innovators in engineering education

Science.gov (United States)

Berry, Ayora

The purpose of this study was to investigate the effects of a curriculum design-based (CDB) professional development model on K-12 teachers' capacity to integrate engineering education in the classroom. This teacher professional development approach differs from other training programs where teachers learn how to use a standard curriculum and adopt it in their classrooms. In a CDB professional development model teachers actively design lessons, student resources, and assessments for their classroom instruction. In other science, technology, engineering and mathematics (STEM) disciplines, CDB professional development has been reported to (a) position teachers as architects of change, (b) provide a professional learning vehicle for educators to reflect on instructional practices and develop content knowledge, (c) inspire a sense of ownership in curriculum decision-making among teachers, and (d) use an instructional approach that is coherent with teachers' interests and professional goals. The CDB professional development program in this study used the Explore-Create-Share (ECS) framework as an instructional model to support teacher-led curriculum design and implementation. To evaluate the impact of the CDB professional development and associated ECS instructional model, three research studies were conducted. In each study, the participants completed a six-month CDB professional development program, the PTC STEM Certificate Program, that included sixty-two instructional contact hours. Participants learned about industry and education engineering concepts, tested engineering curricula, collaborated with K-12 educators and industry professionals, and developed project-based engineering curricula using the ECS framework. The first study evaluated the impact of the CDB professional development program on teachers' engineering knowledge, self-efficacy in designing engineering curriculum, and instructional practice in developing project-based engineering units.

1987-03-01

This normative-descriptive case study of accountability for state school curriculum in South Australia has the following objectives. First, to seek to draw a distinction between accountability and responsibility: terms which have been confused by two South Australian Directors-General of Education (position akin to C.E.O. in the U.K. and Superintendent in the U.S.A.) with important consequences. Second, to present a model of accountability for state school curriculum, by which accountability for such curriculum may be judged democratic or non-democratic, and against which accountability for curriculum in South Australian state schools will be gauged. Third, to show that whilst the South Australian school system exhibits a large measure of bureaucratic or technocratic accountability for curriculum, there is no effective democratic accountability for curriculum, and to indicate a remedy for this situation. Finally, to point out the wider significance of the South Australian case study, and suggest that democracies currently re-structuring their educational systems would do well to keep the need for democratic accountability foremost in mind.

Development of Whole Slide Imaging on Smartphones and Evaluation With ThinPrep Cytology Test Samples: Follow-Up Study.

The smartphone-based whole slide imaging (WSI) system represents a low-cost and effective alternative to automatic scanners for telepathology. In a previous study, the development of one such solution, named scalable whole slide imaging (sWSI), was presented and analyzed. A clinical evaluation of its iOS version with 100 frozen section samples verified the diagnosis-readiness of the produced virtual slides. The first aim of this study was to delve into the quantifying issues encountered in the development of an Android version. It should also provide insights into future high-resolution real-time feedback medical imaging apps on Android and invoke the awareness of smartphone manufacturers for collaboration. The second aim of this study was to further verify the clinical value of sWSI with cytology samples. This type is different from the frozen section samples in that they require finer detail on the cellular level. During sWSI development on Android, it was discovered that many models do not support uncompressed camera pixel data with sufficient resolution and full field of view. The proportion of models supporting the optimal format was estimated in a test on 200 mainstream Android models. Other factors, including slower processing speed and camera preview freezing, also led to inferior performance of sWSI on Android compared with the iOS version. The processing speed was mostly determined by the central processing unit frequency in theory, and the relationship was investigated in the 200-model simulation experiment with physical devices. The camera preview freezing was caused by the lag between triggering photo capture and resuming preview. In the clinical evaluation, 100 ThinPrep cytology test samples covering 6 diseases were scanned with sWSI and compared against the ground truth of optical microscopy. Among the tested Android models, only 3.0% (6/200) provided an optimal data format, meeting all criteria of quality and efficiency. The image-processing speed

Curriculum theory in physical education

Science.gov (United States)

Jewett, Ann E.

1989-03-01

Primary current concerns of curriculum theorists in sport and physical education relate to clarification of value orientations underlying curricular decision-making, selection and statement of curriculum goals, identification and organization of programme content, and the process of curriculum change. Disciplinary mastery is the most traditional value orientation and that which is most frequently found in practice. Curriculum theorists have identified four other value orientations for study: social reconstruction, self-actualization, learning process, and ecological validity. Health-related fitness and the development of motor skills have long been the primary goals of physical education. In recent years, however, curriculum specialists have begun to assign higher priorities to goals of personal integration and challenge, of social development and multicultural understanding. There is general agreement that human movement activities constitute the subject-matter of the sport and physical education curriculum. Differences exist, however, as to how learning activities should be selected for particular programmes. The current trend in seeking better understanding of content is toward studying the operational curriculum with particular attention to the historical and social contexts. An important contemporary focus is the need to translate short-term results into lifestyle changes. The curriculum in sports and physical education should be viewed as a multitude of possibilities.

Consensus builds on population policy as ICPD PrepCom meetings conclude. Vatican objections firm and vocal.

Science.gov (United States)

1994-04-29

In April, 1994, at UN headquarters in New York, delegates from almost 200 countries and nongovernmental organizations (NGOs) negotiated a Programme of Action to be ratified following more debate at the International Conference on Population and Development in Cairo in September. A sizable consensus emerged for this Preparatory Committee III (PrepCom) meeting. It has an expanded view of population policy that centers more on meeting individual needs and less on achieving strict demographic goals. Thus, it focuses on the unmet need for reproductive health services (family planning, basic women's health care, and services linked to sexually transmitted diseases). It considers women's status and female education as being important themselves as well as key determinants of fertility rates. Disagreement over access to abortion services and reproductive health services for adolescents remain. Unlike earlier world conferences, most of the world is working towards a consensus, while the Vatican and just a few small countries (Benin, Malta, Honduras, and Nicaragua) object to these services. Some topics that US National Conference of Catholic Bishops did not want in the Programme of Action were references to reducing the incidence of unsafe abortion, promoting condom use to prevent HIV/AIDS, and even safe motherhood. The US and Japan have committed sizable increases in population assistance. Some European countries are concerned about how their contributions would be allocated. US Undersecretary for Global Affairs and a mostly female 23-member US delegation attended PrepCom III. Most of the US delegates were from NGOs. Many country delegates were women. Many countries accepted recommendations of the women's caucus. The US's priorities are promotion of universal access to the full range of high quality family planning and reproductive health services; increasing women's status; child survival promotion; serving adolescent needs; augmenting the role and responsibility of men in

Background Infection with HIV-1 may result in severe cognitive and motor impairment, referred to as HIV-1-associated dementia (HAD). While its prevalence has dropped significantly in the era of combination antiretroviral therapy, milder neurocognitive disorders persist with a high prevalence. To identify additional therapeutic targets for treating HIV-associated neurocognitive disorders, several candidate gene polymorphisms have been evaluated, but few have been replicated across multiple studies. Methods We here tested 7 candidate gene polymorphisms for association with HAD in a case-control study consisting of 86 HAD cases and 246 non-HAD AIDS patients as controls. Since infected monocytes and macrophages are thought to play an important role in the infection of the brain, 5 recently identified single nucleotide polymorphisms (SNPs) affecting HIV-1 replication in macrophages in vitro were also tested. Results The CCR5 wt/Δ32 genotype was only associated with HAD in individuals who developed AIDS prior to 1991, in agreement with the observed fading effect of this genotype on viral load set point. A significant difference in genotype distribution among all cases and controls irrespective of year of AIDS diagnosis was found only for a SNP in candidate gene PREP1 (p = 1.2×10−5).

Full Text Available BACKGROUND: Infection with HIV-1 may result in severe cognitive and motor impairment, referred to as HIV-1-associated dementia (HAD. While its prevalence has dropped significantly in the era of combination antiretroviral therapy, milder neurocognitive disorders persist with a high prevalence. To identify additional therapeutic targets for treating HIV-associated neurocognitive disorders, several candidate gene polymorphisms have been evaluated, but few have been replicated across multiple studies. METHODS: We here tested 7 candidate gene polymorphisms for association with HAD in a case-control study consisting of 86 HAD cases and 246 non-HAD AIDS patients as controls. Since infected monocytes and macrophages are thought to play an important role in the infection of the brain, 5 recently identified single nucleotide polymorphisms (SNPs affecting HIV-1 replication in macrophages in vitro were also tested. RESULTS: The CCR5 wt/Δ32 genotype was only associated with HAD in individuals who developed AIDS prior to 1991, in agreement with the observed fading effect of this genotype on viral load set point. A significant difference in genotype distribution among all cases and controls irrespective of year of AIDS diagnosis was found only for a SNP in candidate gene PREP1 (p = 1.2 × 10(-5. Prep1 has recently been identified as a transcription factor preferentially binding the -2,518 G allele in the promoter of the gene encoding MCP-1, a protein with a well established role in the etiology of HAD. CONCLUSION: These results support previous findings suggesting an important role for MCP-1 in the onset of HIV-1-associated neurocognitive disorders.

Eisenmann, Tammy

This research examines how the same teacher implements the same curriculum material in two different schools. The aim of the study is to examine how the enacted algebra curriculum may change when the same teacher enacts the same written curriculum materials in different classes. This research comprises two case studies. Each case examines one teacher who taught the beginning of the mathematical topic "equivalent algebraic expressions", to two 7th grade classes from different schools. The same textbook was used in all four classes. The data collected includes: 1. Observations: 25930 lessons throughout the school year in each of the participating classes; Other mathematics classes in each of the schools; Other non9mathematics classes in the participating classes. A total of 130 lessons were observed. The observations included continuous observations of the teaching of "equivalent algebraic expressions" (15919 lessons) in each class. These observations are the main data source of this research; 2. Interviews with the teachers; 3. Informal conversations; and 4. Field notes. The data was analyzed both through quantitative and qualitative analysis. The research focuses on the following two aspects of the enacted curriculum: implementation of the recommendation that appeared in the curriculum materials and the types of algebraic activity that the students were exposed to during the teaching of the mathematical topic. Kieran's framework (Kieran, 1996, 2004), which distinguishes between three types of algebraic activities 9 generational, transformational and global/meta9level 9 was employed for the examination of the algebraic activities. Comparisons were made for two aspects of the research: between the enacted curriculum in each of the classes and the curriculum materials; and between each of the classes taught by same teacher. It was found that in case study 1, that examined teacher Sara and schools Carmel and Tavor -- most of the recommendations for instruction that

The aim of the present study is to obtain the time density curves of the contrast-enhanced CT of hepatic portal vein, hepatic and splenic parenchyma, and to examine the relation with age, body weight, type of liver dysfunction. Subjects were 32 patients with liver tumors or liver diseases. For this purpose, the procedure of hepatic CT was monitored by Smart Prep and the images of whole liver was taken when the level of the contrast at the hepatic portal vein reached to the enhancement threshold. The contrast medium used was Iomeprol 300. The adverse reactions by Iomeprol 300 were mild and any treatment did not need. There was no correlation age and weight with enhancement threshold at the hepatic portal vein and peak time at the splenic parenchyma. The enhancement threshold at the hepatic portal vein was various in patients with chrrhosis and chronic hepatitis, and tended to be delayed in patients with chrrhosis. The peak time of the splenic parenchyma was up to 52 seconds in all patients with chronic hepatitis. The shortage of the enhancement threshold and the increase in blood flow at arterial early phase were observed in the patients with advanced acute hepatitis. This method should be examined more cases with various hepatic diseases. (K.H.)

Educational Borrowing and Mathematics Curriculum: Realistic Mathematics Education in the Dutch and Indonesian Primary Curriculum

Directory of Open Access Journals (Sweden)

Shintia Revina

2018-02-01

Full Text Available Since the late 1990s, Indonesian mathematics educators have considered Realistic Mathematics Education (RME, the Dutch approach to mathematics instruction, to be the basis for educational reform. In the National curriculum development, RME has, therefore, been reviewed as among the theoretical references to the curriculum goals and content. In the present study, an analysis of the consistency between RME and the curriculum descriptors and contents in Indonesia is presented. This is supplemented with some comparisons to that in the Netherlands. Findings in this study revealed that while most of RME principles are reflected in the Indonesian curriculum, the descriptions were often very general and less explicit compared to the Dutch curriculum. They were also limited by the content-based approach as well as by the centralized decision making process of the contents to be taught which have been pre-determined at the national level. This study suggests future research to see how the curriculum may influence teachers’ enactment of RME at classroom level.

One of the most significant elements of entrepreneurship curriculum design is teaching-learning methods, which plays a key role in studies and researches related to such a curriculum. It is the teaching method, and systematic, organized and logical ways of providing lessons that should be consistent with entrepreneurship goals and contents, and should also be developed according to the learners' needs. Therefore, the current study aimed to introduce appropriate, modern, and effective methods of teaching entrepreneurship and their validation. This is a mixed method research of a sequential exploratory kind conducted through two stages: a) developing teaching methods of entrepreneurship curriculum, and b) validating developed framework. Data were collected through "triangulation" (study of documents, investigating theoretical basics and the literature, and semi-structured interviews with key experts). Since the literature on this topic is very rich, and views of the key experts are vast, directed and summative content analysis was used. In the second stage, qualitative credibility of research findings was obtained using qualitative validation criteria (credibility, confirmability, and transferability), and applying various techniques. Moreover, in order to make sure that the qualitative part is reliable, reliability test was used. Moreover, quantitative validation of the developed framework was conducted utilizing exploratory and confirmatory factor analysis methods and Cronbach's alpha. The data were gathered through distributing a three-aspect questionnaire (direct presentation teaching methods, interactive, and practical-operational aspects) with 29 items among 90 curriculum scholars. Target population was selected by means of purposive sampling and representative sample. Results obtained from exploratory factor analysis showed that a three factor structure is an appropriate method for describing elements of teaching-learning methods of entrepreneurship curriculum

In Bangalore, new HIV infections of female sex workers and men who have sex with men continue to occur, despite high condom use. Pre-exposure prophylaxis (PrEP) has high anti-HIV efficacy for men who have sex with men. PrEP demonstration projects are underway amongst Indian female sex workers. We estimated the impact and efficiency of prioritizing PrEP to female sex workers and/or men who have sex with men in Bangalore. A mathematical model of HIV transmission and treatment for female sex workers, clients, men who have sex with men and low-risk groups was parameterized and fitted to Bangalore data. The proportion of transmission attributable (population attributable fraction) to commercial sex and sex between men was calculated. PrEP impact (infections averted, life-years gained) and efficiency (life-years gained/infections averted per 100 person-years on PrEP) were estimated for different levels of PrEP adherence, coverage and prioritization strategies (female sex workers, high-risk men who have sex with men, both female sex workers and high-risk men who have sex with men, or female sex workers with lower condom use), under current conditions and in a scenario with lower baseline condom use amongst key populations. Population attributable fractions for commercial sex and sex between men have declined over time, and they are predicted to account for 19% of all new infections between 2016 and 2025. PrEP could prevent a substantial proportion of infections amongst female sex workers and men who have sex with men in this setting (23%/27% over 5/10 years, with 60% coverage and 50% adherence), which could avert 2.9%/4.3% of infections over 5/10 years in the whole Bangalore population. Impact and efficiency in the whole population was greater if female sex workers were prioritized. Efficiency increased, but impact decreased, if only female sex workers with lower condom use were given PrEP. Greater impact and efficiency was predicted for the scenario with lower condom use

The significant global variations in surgical oncology training paradigms can have a detrimental effect on tackling the rising global cancer burden. While some variations in training are essential to account for the differences in types of cancer and biology, the fundamental principles of providing care to a cancer patient remain the same. The development of a global curriculum in surgical oncology with incorporated essential standards could be very useful in building an adequately trained surgical oncology workforce, which in turn could help in tackling the rising global cancer burden. The leaders of the Society of Surgical Oncology and European Society of Surgical Oncology convened a global curriculum committee to develop a global curriculum in surgical oncology. A global curriculum in surgical oncology was developed to incorporate the required domains considered to be essential in training a surgical oncologist. The curriculum was constructed in a modular fashion to permit flexibility to suit the needs of the different regions of the world. Similarly, recognizing the various sociocultural, financial and cultural influences across the world, the proposed curriculum is aspirational and not mandatory in intent. A global curriculum was developed which may be considered as a foundational scaffolding for training surgical oncologists worldwide. It is envisioned that this initial global curriculum will provide a flexible and modular scaffolding that can be tailored by individual countries or regions to train surgical oncologists in a way that is appropriate for practice in their local environment.

Kadmon, Guni; Schmidt, Jan; De Cono, Nicola; Kadmon, Martina

2011-01-01

Heidelberg Medical School underwent a major curricular change with the implementation of the reform curriculum HeiCuMed (Heidelberg Curriculum Medicinale) in October 2001. It is based on rotational modules with daily cycles of interactive, case-based small-group seminars, PBL tutorials and training of sensomotor and communication skills. For surgical undergraduate training an organisational structure was developed that ensures continuity of medical teachers for student groups and enables their unimpaired engagement for defined periods of time while accounting for the daily clinical routine in a large surgery department of a university hospital. It includes obligatory didactic training, standardising teaching material on the basis of learning objectives and releasing teaching doctors from clinical duties for the duration of a module. To compare the effectiveness of the undergraduate surgical reform curriculum with that of the preceding traditional one as reflected by students' evaluations. The present work analyses student evaluations of the undergraduate surgical training between 1999 and 2008 including three cohorts (~360 students each) in the traditional curriculum and 13 cohorts (~150 students each) in the reform curriculum. The evaluation of the courses, their organisation, the teaching quality, and the subjective learning was significantly better in HeiCuMed than in the preceding traditional curriculum over the whole study period. A medical curriculum based on the implementation of interactive didactical methods is more important to successful teaching and the subjective gain of knowledge than knowledge transfer by traditional classroom teaching. The organisational strategy adopted in the surgical training of HeiCuMed has been successful in enabling the maintenance of a complex modern curriculum on a continuously high level within the framework of a busy surgical environment.

Islamic values in the Kuwaiti curriculum

Science.gov (United States)

Alshahen, Ghanim A.

This study investigated the influence of Islamic values on the curriculum, in particular the Islamic studies and science curricula. Three questionnaires were developed, validated, and used to investigate teachers' and pupils' attitudes toward Islamic values in the curriculum. Four main sections deal with Islamic values in the Islamic studies and science curricula, namely: Islamic values in the textbook, teaching Islamic values, the relationship between Islamic values and the science curriculum, and the Islamic values model. Two instruments were used in this study: questionnaires and interviews. Both qualitative and quantitative data were generated from the sample, which consisted of Islamic studies and science teachers and supervisors in intermediate schools, and pupils studying in the eighth grade in intermediate schools. In the last case, the data were gathered by questionnaire only. The interviews and questionnaires provided explanatory data. The research was carried out in three phases, considering respectively 55 Islamic studies teachers, 55 science teachers who teach the eighth grade in intermediate schools, and 786 pupils who study in the eighth grade in 20 schools. In each school, the researcher selected two classes. This thesis consists of eight chapters. Chapter One provides a general introduction and highlights the general framework of this study. Chapter Two is concerned with the development of the education system in Kuwait and the objectives of the Islamic studies and science curricula in the intermediate stage. Chapter Three presents the conceptions of values, the Islamic values model, and Islamic values in the curriculum. Chapter Four describes the objectives of the study, and its research design methods and procedures used to develop the instruments. The sampling procedure, the data collection procedures, and the statistical methods used to analyse the data are also described. Chapter Five presents and interprets the findings of this study. Data

Mohammad Reza Andarvazh

2018-03-01

Full Text Available Background: The concept of hidden curriculum was first used by Philip Jackson in 1968, and Hafferty brought this concept to the medical education. Many of the subjects that medical students learn are attributed to this curriculum. So far several definitions have been presented for the hidden curriculum, which on the one hand made this concept richer, and on the other hand, led to confusion and ambiguity.This paper tries to provide a clear and comprehensive definition of it.Methods: In this study, concept analysis of McKenna method was used. Using keywords and searching in the databases, 561 English and 26 Persian references related to the concept was found, then by limitingthe research scope, 125 abstracts and by finding more relevant references, 55 articles were fully studied.Results: After analyzing the definitions by McKenna method, the hidden curriculum is defined as follows: The hidden curriculum is a hidden, powerful, intrinsic in organizational structure and culture and sometimes contradictory message, conveyed implicitly and tacitly in the learning environment by structural and human factors and its contents includes cultural habits and customs, norms, values, belief systems, attitudes, skills, desires and behavioral and social expectations can have a positive or negative effect, unplanned, neither planners nor teachers, nor learners are aware of it. The ultimate consequence of the hidden curriculum includes reproducing the existing class structure, socialization, and familiarizing learners for transmission and joining the professional world.Conclusion: Based on the concept analysis, we arrived at an analytical definition of the hidden curriculum that could be useful for further studies in this area.Keywords: CONCEPT ANALYSIS, HIDDEN CURRICULUM, MCKENNA’S METHOD

Can social semantic web techniques foster collaborative curriculum mapping in medicine?

Spreckelsen, Cord; Finsterer, Sonja; Cremer, Jan; Schenkat, Hennig

2013-08-15

Curriculum mapping, which is aimed at the systematic realignment of the planned, taught, and learned curriculum, is considered a challenging and ongoing effort in medical education. Second-generation curriculum managing systems foster knowledge management processes including curriculum mapping in order to give comprehensive support to learners, teachers, and administrators. The large quantity of custom-built software in this field indicates a shortcoming of available IT tools and standards. The project reported here aims at the systematic adoption of techniques and standards of the Social Semantic Web to implement collaborative curriculum mapping for a complete medical model curriculum. A semantic MediaWiki (SMW)-based Web application has been introduced as a platform for the elicitation and revision process of the Aachen Catalogue of Learning Objectives (ACLO). The semantic wiki uses a domain model of the curricular context and offers structured (form-based) data entry, multiple views, structured querying, semantic indexing, and commenting for learning objectives ("LOs"). Semantic indexing of learning objectives relies on both a controlled vocabulary of international medical classifications (ICD, MeSH) and a folksonomy maintained by the users. An additional module supporting the global checking of consistency complements the semantic wiki. Statements of the Object Constraint Language define the consistency criteria. We evaluated the application by a scenario-based formative usability study, where the participants solved tasks in the (fictional) context of 7 typical situations and answered a questionnaire containing Likert-scaled items and free-text questions. At present, ACLO contains roughly 5350 operational (ie, specific and measurable) objectives acquired during the last 25 months. The wiki-based user interface uses 13 online forms for data entry and 4 online forms for flexible searches of LOs, and all the forms are accessible by standard Web browsers. The

The hidden curriculum represents influences occurring within the culture of medicine that indirectly alter medical professionals' interactions, beliefs and clinical practices throughout their training. One approach to increase medical student awareness of the hidden curriculum is to provide them with readily available examples of how it is enacted in medicine; as such the purpose of this study was to examine depictions of the hidden curriculum in popular medical television programs. One full season of ER, Grey's Anatomy and Scrubs were selected for review. A summative content analysis was performed to ascertain the presence of depictions of the hidden curriculum, as well as to record the type, frequency and quality of examples. A second reviewer also viewed a random selection of episodes from each series to establish coding reliability. The most prevalent themes across all television programs were: the hierarchical nature of medicine; challenges during transitional stages in medicine; the importance of role modeling; patient dehumanization; faking or overstating one's capabilities; unprofessionalism; the loss of idealism; and difficulties with work-life balance. The hidden curriculum is frequently depicted in popular medical television shows. These examples of the hidden curriculum could serve as a valuable teaching resource in undergraduate medical programs.

To design and evaluate a research mentor training curriculum for clinical and translational researchers. The resulting 8-hour curriculum was implemented as part of a national mentor training trial. The mentor training curriculum was implemented with 144 mentors at 16 academic institutions. Facilitators of the curriculum participated in a train-the-trainer workshop to ensure uniform delivery. The data used for this report were collected from participants during the training sessions through reflective writing, and following the last training session via confidential survey with a 94% response rate. A total of 88% of respondents reported high levels of satisfaction with the training experience, and 90% noted they would recommend the training to a colleague. Participants also reported significant learning gains across six mentoring competencies as well as specific impacts of the training on their mentoring practice. The data suggest the described research mentor training curriculum is an effective means of engaging research mentors to reflect upon and improve their research mentoring practices. The training resulted in high satisfaction, self-reported skill gains as well as behavioral changes of clinical and translational research mentors. Given success across 16 diverse sites, this training may serve as a national model. © 2012 Wiley Periodicals, Inc.

The degree of exposure to pediatric and adolescent gynecology (PAG) varies across residency programs in obstetrics and gynecology and pediatrics. Nevertheless, these programs are responsible for training residents and providing opportunities within their programs to fulfill PAG learning objectives. To that end, the North American Society for Pediatric and Adolescent Gynecology has taken a leadership role in PAG resident education by creating and systematically updating the Short Curriculum. This curriculum outlines specific learning objectives that are central to PAG education and lists essential resources for learners' reference.

Objectives. We sought to develop a curriculum and collaboration model for law enforcement and mental health services in Liberia, West Africa. Methods. In 2013 we conducted key informant interviews with law enforcement officers, mental health clinicians, and mental health service users in Liberia, and facilitated a 3-day curriculum workshop. Results. Mental health service users reported prior violent interactions with officers. Officers and clinicians identified incarceration and lack of treatment of mental health service users as key problems, and they jointly drafted a curriculum based upon the Crisis Intervention Team (CIT) model adapted for Liberia. Officers’ mental health knowledge improved from 64% to 82% on workshop assessments (t = 5.52; P < .01). Clinicians’ attitudes improved (t = 2.42; P = .03). Six months after the workshop, 69% of clinicians reported improved engagement with law enforcement. Since the Ebola outbreak, law enforcement and clinicians have collaboratively addressed diverse public health needs. Conclusions. Collaborations between law enforcement and mental health clinicians can benefit multiple areas of public health, as demonstrated by partnerships to improve responses during the Ebola epidemic. Future research should evaluate training implementation and outcomes including stigma reduction, referrals, and use of force. PMID:25602903

To assess the feasibility and acceptability of a game-based sexuality education curriculum. Curriculum evaluation used descriptive statistics, observation, and qualitative and quantitative data collection. The study was conducted in eighth grade classrooms in Chicago, Illinois. Students from 3 eighth grade classrooms from a school using a game-based curriculum. The intervention had 11 modules and used an ecological model informed by the extant literature. The intervention was developed by the Game Changer Chicago Design Lab and featured a card game designed with youth participation. The study outcomes of interest included learning, feasibility, and acceptability of the curriculum. Students highly rated frank conversation via "Ask the Doctor" sessions and role-playing. Students raised concerns about the breadth of activities, preferring to explore fewer topics in greater depth. A game-based curriculum was feasible, yet students placed the highest value on frank discussion about sexuality. Copyright © 2016 North American Society for Pediatric and Adolescent Gynecology.

2018-01-01

Background Intimate partner violence (IPV) has been recognized as a public health problem since the late 20th century. To spur IPV prevention efforts nationwide, the DELTA PREP Project selected 19 state domestic violence coalitions to build organizational prevention capacity and catalyze IPV primary prevention strategies within their states. Objective DELTA PREP’s summative evaluation addressed four major questions: (1) Did coalitions improve their prevention capacity during the project period? (2) Did coalitions serve as catalysts for prevention activities within their states during the project period? (3) Was initial prevention capacity associated with the number of prevention activity types initiated by coalitions by the end of the project? (4) Did coalitions sustain their prevention activities 6 months after the end of the project period? Results DELTA PREP achieved its capacity-building goal, with all 19 participant coalitions integrating prevention within their organizations and serving as catalysts for prevention activities in their states. At 6 months follow up, coalitions had sustained almost all prevention activities they initiated during the project. Baseline prevention capacity (Beginner vs. Intermediate) was not associated with the number of prevention activity types coalitions implemented by the end of the project. Conclusion Service and treatment organizations are increasingly asked to integrate a full spectrum of prevention strategies. Selecting organizations that have high levels of general capacity and readiness for an innovation like integrating a public health approach to IPV prevention will likely increase success in building an innovation-specific capacity, and in turn implementing an innovation.

1990-01-01

In these times of increased spending to finance new capacity and to meet clean air act legislation, many electric utilities are giving a high priority to controlling capital expenditures at existing generating facilities. Determining the level of capital expenditures which are economically justified is very difficult; units which have higher capacity factors are worth more to the utility. Therefore, the utility can more readily justify higher capital expenditures to improve or maintain reliability and heat rate than on units with lower capacity factors. This paper describes a PC-based computer program (PREPS2) which performs an economic analysis of individual capital projects. The program incorporates tables which describe the worth to the system of making improvements in each unit. This computer program is currently being used by the six Southern Company operating companies to evaluate all production capital projects over $50,000. Approximately 500 projects representing about $300 million are being analyzed each year

Objective To compare the accuracy of liquid based cytology using the computerised ThinPrep Imager with that of manually read conventional cytology. Design Prospective study. Setting Pathology laboratory in Sydney, Australia. Participants 55 164 split sample pairs (liquid based sample collected after conventional sample from one collection) from consecutive samples of women choosing both types of cytology and whose specimens were examined between August 2004 and June 2005. Main outcome measures Primary outcome was accuracy of slides for detecting squamous lesions. Secondary outcomes were rate of unsatisfactory slides, distribution of squamous cytological classifications, and accuracy of detecting glandular lesions. Results Fewer unsatisfactory slides were found for imager read cytology than for conventional cytology (1.8% v 3.1%; Pcytology (7.4% v 6.0% overall and 2.8% v 2.2% for cervical intraepithelial neoplasia of grade 1 or higher). Among 550 patients in whom imager read cytology was cervical intraepithelial neoplasia grade 1 or higher and conventional cytology was less severe than grade 1, 133 of 380 biopsy samples taken were high grade histology. Among 294 patients in whom imager read cytology was less severe than cervical intraepithelial neoplasia grade 1 and conventional cytology was grade 1 or higher, 62 of 210 biopsy samples taken were high grade histology. Imager read cytology therefore detected 71 more cases of high grade histology than did conventional cytology, resulting from 170 more biopsies. Similar results were found when one pathologist reread the slides, masked to cytology results. Conclusion The ThinPrep Imager detects 1.29 more cases of histological high grade squamous disease per 1000 women screened than conventional cytology, with cervical intraepithelial neoplasia grade 1 as the threshold for referral to colposcopy. More imager read slides than conventional slides were satisfactory for examination and more contained low grade cytological

Family meetings in the intensive care unit are associated with beneficial outcomes for patients, their families, and health care systems, yet these meetings often do not occur in a timely, effective, reliable way. The Department of Veterans Affairs Comprehensive End-of-Life Care Implementation Center sponsored a national initiative to improve family meetings in Veterans Affairs intensive care units across the United States. Process measures of success for the initiative were identified, including development of a curriculum to support facility-based quality improvement projects to implement high-quality family meetings. Identified curriculum requirements included suitability for distance learning and applicability to many clinical intensive care units. Curriculum modules were cross-mapped to the "Plan-Do-Study-Act" model to aid in planning quality improvement projects. A questionnaire was e-mailed to users to evaluate the curriculum's effectiveness. Users rated the curriculum's effectiveness in supporting and achieving aims of the initiative as 3.6 on a scale of 0 (not effective) to 4 (very effective). Users adapted the curriculum to meet local needs. The number of users increased from 6 to 17 quality improvement teams in 2 years. All but 3 teams progressed to implementation of an action plan. Users were satisfied with the effectiveness and adaptability of a family-meeting quality improvement curriculum to support implementation of a quality improvement project in Veterans Affairs intensive care units. This tool may be useful in facilitating projects to improve the quality of family meetings in other intensive care units. ©2017 American Association of Critical-Care Nurses.

Proper integration of newly emerging digital assessment tools is a central issue in dental education in an effort to provide more accurate and objective feedback to students. The study examined how the outcomes of students' tooth preparation were correlated when evaluated using traditional faculty assessment and two types of digital assessment approaches. Specifically, incorporation of the Romexis Compare 2.0 (Compare) and Sirona prepCheck 1.1 (prepCheck) systems was evaluated. Additionally, satisfaction of students based on the type of software was evaluated through a survey. Students in a second-year pre-clinical prosthodontics course were allocated to either Compare (n = 42) or prepCheck (n = 37) systems. All students received conventional instruction and used their assigned digital system as an additional evaluation tool to aid in assessing their work. Examinations assessed crown preparations of the maxillary right central incisor (#8) and the mandibular left first molar (#19). All submissions were graded by faculty, Compare and prepCheck. Technical scores did not differ between student groups for any of the assessment approaches. Compare and prepCheck had modest, statistically significant correlations with faculty scores with a minimum correlation of 0.3944 (P = 0.0011) and strong, statistically significant correlations with each other with a minimum correlation of 0.8203 (P < 0.0001). A post-course student survey found that 55.26% of the students felt unfavourably about learning the digital evaluation protocols. A total of 62.31% felt favourably about the integration of these digital tools into the curriculum. Comparison of Compare and prepCheck showed no evidence of significant difference in students' prosthodontics technical performance and perception. © 2016 John Wiley & Sons A/S.

The Discourse of a Preschool Education Curriculum

Directory of Open Access Journals (Sweden)

Lidija Miškeljin

2016-02-01

Full Text Available The paper presents a critical analysis of the discourse of a preschool education curriculum. Its starting point is Foucault’s concept of discourse as language in use, which not only reflects the social order, but also shapes it through a network of conventions, knowledge and practices determining man’s – or, in this case, the reader’s – perception of reality. The analysis is based on identifying the discourse strategies and/or systems of rules laid out in the text The basic principles of the preschool education curriculum for three- to seven-year-old children – model A which make possible certain statements and insights regarding children and thus position the child and the preschool teacher by means of discourse repertoires. This approach helps contextualize the text and leads to an understanding of the basic discourse mechanism involved in the creation of specific versions of preschool education. As discourse analysis itself is related to interpretation and narratology, with the story as a constant, so is this paper a story about a preschool curriculum, for, like any other text, it tells an unfinished story that can yet evolve in different directions.

The vast majority of PBL experience is in basic science courses. Application of classic Problem based learning in clerkship phase is challenging. Although the clinical case is considered a problem, yet solving this problem following the burrow's law has faced hurdles. The difficulties are facing the learner, the teacher and curricula. We implement innovative curriculum for the clerkship year in internal medicine course. We surveyed the student just before coming to an internal medicine course to ask them about continuing PBL or other types of learning in clinical years. A committee was created to study the possible ways to integrate PBL in the course. After multiple brainstorming meeting, an innovated curriculum was implemented. Student surveyed again after they completed their course. The survey is asking them about what is the effect of the implemented curriculum in their skills, attitude, and knowledge. 70% of Students, who finished their basic science in PBL, preferred not to have classical PBL, but more a clinical oriented case based curriculum in the clinical years. After this innovated curriculum, 50-60 % of students who completed it showed a positive response in all aspects of effects including skill, attitude, and knowledge. The Innovated curriculum includes daily morning report, 3 bedside teaching, investigation session, and clinical reasoning weekly, and Lectures up to twice a week. We suggest implementing a curriculum with PBL and case-based criteria in clinical phase are feasible, we are providing a framework with this innovated curriculum.

A regional oxygen model of the Washington and Oregon shelves (Siedlecki, S.A., Banas, N., Davis, K.A., Giddings, S., P. MacCready, Connolly, T., & B. Hickey. Seasonal Oxygen variability on the continental shelves of Washington and Oregon, in prep) is combined with the empirical relationships between the carbonate system, oxygen and temperature (Alin et al, in prep) to simulate the carbonate chemistry in this region. A model hindcast for 2009 is compared to local observations of oxygen, and aragonite saturation. The model is able to reproduce the seasonal change in oxygen observed on the Oregon shelf. Challenges of this approach are discussed. The volume of hypoxic and undersaturated water increases over the upwelling season, occupying more of the water column later in the upwelling season. This results in increasingly stressful conditions over most of the water column for biota on the shelf as the upwelling season progresses. How the rate of ascension and presence of this undersaturated water varies regionally will be discussed.

Horizontal integration of the basic sciences in the chiropractic curriculum.

2010-01-01

Basic science curricula at most chiropractic colleges consist of courses (eg, general anatomy, physiology, biochemistry, etc) that are taught as stand-alone content domains. The lack of integration between basic science disciplines causes difficulties for students who need to understand how the parts function together as an integrated whole and apply this understanding to solving clinical problems. More horizontally integrated basic science curricula could be achieved by several means: integrated Part I National Board of Chiropractic Examiners questions, a broader education for future professors, an increased emphasis on integration within the current model, linked courses, and an integrated, thematic basic science curriculum. Horizontally integrating basic science curricula would require significant efforts from administrators, curriculum committees, and instructional faculty. Once in place this curriculum would promote more clinically relevant learning, improved learning outcomes, and superior vertical integration.

2015-12-01

Queensland schools are currently teaching with the first National Curriculum for Australia. This new curriculum was one of a number of political responses to address the recurring low scores in literacy, mathematics, and science that continue to hold Australia in poor international rankings. Teachers have spent 2 years getting to know the new science curriculum through meetings, training, and exploring the new Australian curriculum documents. This article examines the support and preparation for implementation provided in two regional schools, with a closer look at six specific teachers and their science teaching practices as they attempted to implement the new science curriculum. The use of a survey, field observations, and interviews revealed the schools' preparation practices and the teachers' practices, including the support provided to implement the new science curriculum. A description and analysis of school support and preparation as well as teachers' views of their experiences implementing the new science curriculum reveal both achievements and shortcomings. Problematic issues for the two schools and teachers include time to read and comprehend the curriculum documents and content expectations as well as time to train and change the current processes effectively. The case teachers' experiences reveal implications for the successful and effective implementation of new curriculum and curriculum reform.

2017-04-01

Purpose  Scope and clinical importance of interventional radiology markedly evolved over the last decades. Consequently it was acknowledged as independent subspecialty by the "European Union of Medical Specialists" (UEMS). Based on radiological imaging techniques Interventional Radiology is an integral part of Radiology. Materials und Methods  In 2009 the German Society for Interventional Radiology and minimally-invasive therapy (DeGIR) developed a structured training in Interventional Radiology. In cooperation with the German Society of Neuroradiology (DGNR) this training was extended to also cover Interventional Neuroradiology in 2012. Tailored for this training in Interventional Radiology a structured curriculum was developed, covering the scope of this modular training. Results  The curriculum is based on the DeGIR/DGNR modular training concept in Interventional Radiology. There is also an European Curriculum and Syllabus for Interventional Radiology developed by the "Cardiovascular and Interventional Radiological Society of Europe" (CIRSE). The presented curriculum in Interventional Radiology is designed to provide a uniform base for the training in Interventional Radiology in Germany, based on the competencies obtained during residency. Conclusion  This curriculum can be used as a basis for training in Interventional Radiology by all training sites. Key Points: · Interventional Radiology is an integral part of clinical radiology. · The German Society for Interventional Radiology and minimally-invasive therapy (DeGIR) developed a curriculum in Interventional Radiology. · This curriculum is an integrative basis for the training in interventional.

Grayling, Ian

2012-01-01

Full Text Available In this paper we, firstly, explore the importance and positioning of ‘thinking skills’ within the Further Education (FE curriculum in hard times - for society generally and education in particular. Secondly, we argue that ‘thinking skills’ have been lost from the curriculum over recent years and are now in urgent need of rehabilitation; not as a bolt-on, but at the heart of the curriculum. We then invite readers to consider the Learning and Skills Improvement Service’s (LSIS endorsed framework for ‘Spiritual, Moral, Social and Cultural’ education as a powerful means of re-embedding ‘thinking’ within the vocational curriculum in support of both the ‘skills’ and the ‘social cohesion’ agendas. Finally, we consider the implications of this for the development of vocational pedagogy and for teacher education.

Background: The HIV/AIDS epidemic in Vietnam is concentrated in subgroups of the population, including men who have sex with men (MSM). Pre-exposure prophylaxis (PrEP) is a viable strategy for HIV prevention, but knowledge about and preferences for PrEP delivery among Vietnamese MSM are not well understood. Methods: In 2015, an online survey was conducted with recruitment via social networking websites for MSM and peer recruitment. A description of daily oral, long-acting injectable, and rectal microbicide formulations of PrEP was provided to participants. Participants were asked about their prior awareness of and interest in PrEP, and ranked their most preferred PrEP modality. Multivariable logistic regression models were used to assess factors associated with having heard of PrEP and preference for each PrEP modality. Results: Of 548 participants who answered demographic and PrEP-related questions, 26.8% had previously heard of PrEP and most (65.7%) endorsed rectal microbicides as their most preferred PrEP delivery modality. Commonly-cited perceived barriers to uptake of PrEP included concern about side-effects, perception about being HIV positive, and family or friends finding out about their sexual behaviour. In multivariable models, older participants less often endorsed rectal microbicides (adjusted odds ratio (AOR) 0.95 per year, 95% confidence interval (CI) 0.91-0.99) and more often endorsed long-acting injectables (AOR 1.08 per year, 95% CI 1.03 to 1.14) as their preferred PrEP modality. Participants who were willing to pay more for PrEP less often endorsed rectal microbicides (AOR 0.81, 95% CI 0.72-0.92) and more often endorsed long-acting injectables (AOR 1.17, 95% CI 1.01-1.35) and daily oral pills (AOR 1.16, 95% CI 1.00-1.35) as their preferred form of PrEP. Conclusions: A variety of PrEP modalities were acceptable to MSM in Vietnam, but low knowledge of PrEP may be a barrier to implementation.

To determine the feasibility and effectiveness of a learner-created virtual patient (VP) curriculum for postgraduate year 2 surgical residents. Using a social-constructivist model of learning, we designed a learner-created VP curriculum to help postgraduate year 2 residents prepare for their in-training surgical examination. Each resident was assigned to create a VP curriculum based on the learning objectives for this examination, and VP cases were then disseminated to all residents for completion. To measure the learning effects of the curriculum, participants completed 2 simulated in-training examinations, both at the beginning and at the end of the intervention. Study participants also participated in a focus group and completed an online questionnaire about the perceived learning value of the curriculum. The study was conducted at the McGill University Health Centre, a tertiary care hospital in Montreal, Canada. In total, 24 residents from 7 surgical specialties completed both the pretest and posttest, as well as took part in the creation of a VP curriculum. Of those 24 residents, only 19 residents completed the cases created by their peers, with 7 completing greater than 50% of the cases and 12 completing less than 50%. In all 17 residents responded to the online questionnaire and 11 residents participated in the focus group. The VP curriculum failed to improve scores from pretest (59.6%, standard deviation = 8.1) to posttest (55.4%, standard deviation = 6.6; p = 0.01) on the simulated in-training examination. Nonetheless, survey results demonstrated that most residents felt that creating a VP case (89%) and completing cases created by their peers (71%) had educational value. Overall, 71% preferred active participation in a curriculum to traditional didactic teaching. The focus group identified time-related constraints, concern about the quality of the peer-created cases, and questioning of the relationship between the curriculum and the Surgical Foundations

The academic half-day (AHD) curriculum is an alternative to the traditional noon conference in graduate medical education, yet little is known regarding its effect on knowledge acquisition and resident satisfaction. We investigated the association between the 2 approaches for delivering the curriculum and knowledge acquisition, as reflected by the Internal Medicine In-Training Examination (IM-ITE) scores and assessed resident learning satisfaction under both curricula. The Cleveland Clinic Internal Medicine Residency Program transitioned from the noon conference to the AHD curriculum in 2011. Covariates for residents enrolled from 2004 to 2011 were age; sex; type of medical degree; United States Medical Licensing Examination Step 1, 2 Clinical Knowledge; and IM-ITE-1 scores. We performed univariable and multivariable linear regressions to investigate the association between covariates and IM-ITE-2 and IM-ITE-3 scores. Residents also were surveyed about their learning satisfaction in both curricula. Of 364 residents, 112 (31%) and 252 (69%) were exposed to the AHD and the noon conference curriculum, respectively. In multivariable analyses, the AHD curriculum was associated with higher IM-ITE-3 (regression coefficient, 4.8; 95% confidence interval 2.9-6.6) scores, and residents in the AHD curriculum had greater learning satisfaction compared with the noon conference cohort (Likert, 3.4 versus 3.0; P  =  .003). The AHD curriculum was associated with improvement in resident medical knowledge acquisition and increased learner satisfaction.

2014-03-01

Full Text Available Objective: To understand how the formal curriculum experience of an Australian undergraduate pharmacy program supports students’ professional identity formation. Methods: A qualitative ethnographic study was conducted over four weeks using participant observation and examined the ‘typical’ student experience from the perspective of a pharmacist. A one-week period of observation was undertaken with each of the four year groups (that is, for years one to four comprising the undergraduate curriculum. Data were collected through observation of the formal curriculum experience using field notes, a reflective journal and informal interviews with 38 pharmacy students. Data were analyzed thematically using an a priori analytical framework. Results: Our findings showed that the observed curriculum was a conventional curricular experience which focused on the provision of technical knowledge and provided some opportunities for practical engagement. There were some opportunities for students to imagine themselves as pharmacists, for example, when the lecture content related to practice or teaching staff described their approach to practice problems. However, there were limited opportunities for students to observe pharmacist role models, experiment with being a pharmacist or evaluate their professional identities. While curricular learning activities were available for students to develop as pharmacists e.g. patient counseling, there was no contact with patients and pharmacist academic staff tended to role model as educators with little evidence of their pharmacist selves. Conclusion: These findings suggest that the current conventional approach to the curriculum design may not be fully enabling learning experiences which support students in successfully negotiating their professional identities. Instead it appeared to reinforce their identities as students with a naïve understanding of professional practice, making their future transition to

Innovative curriculum designs are vital for effective learning in contemporary nursing education where traditional modes of delivery are not adequate to meet the learning needs of postgraduate students. This instance of postgraduate teaching in a distributed learning environment offered the opportunity to design a flexible learning model for teaching advanced clinical skills. To present a sustainable model for flexible learning that enables specialist nurses to gain postgraduate qualifications without on-campus class attendance by teaching and assessing clinical health care skills in an authentic workplace setting. An action research methodology was used to gather evidence and report on the process of curriculum development of a core unit, Comprehensive Health Assessment (CHA), within 13 different postgraduate speciality courses. Qualitative data was collected from 27 teaching academics, 21 clinical specialist staff, and 7 hospital managers via interviews, focus groups and journal reflections. Evaluations from the initial iteration of CHA from 36 students were obtained. Data was analyzed to develop and evaluate the curriculum design of CHA. The key factors indicated by participants in the curriculum design process were coordination and structuring of teaching and assessment; integration of content development; working with technologies, balancing specialities and core knowledge; and managing induction and expectations. A set of recommendations emerged as a result of the action research process. These included: a constructive alignment approach to curriculum design; the production of a facilitator's guide that specifies expectations and unit information for academic and clinical education staff; an agreed template for content authors; and the inclusion of synchronous communication for real-time online tutoring. The highlight of the project was that it built curriculum design capabilities of clinicians and students which can sustain this alternative model of online

Extended professional development for systemic curriculum reform

Kubitskey, Mary Elizabeth

Education standards call for adopting inquiry science instruction. Successful adoption requires professional development (PD) to support teachers, increasing the need for research on PD. This dissertation examines the question: What is the influence of high quality, curriculum aligned, long-term group workshops and related practice on teacher learning? I focus on the following subquestions: (1) What is the influence of high quality, curriculum aligned, long-term, group workshops on teacher knowledge and beliefs? (2) What is the impact of the workshops on teacher practice? (3) What is the influence of practice on student response? (4) What is the impact of practice and student response on teacher knowledge and beliefs? I focus on an instance of PD nested within a long-term systemic change initiative, tracing eleven science teachers' learning from workshops and associated enactments. The data included pre and post-unit interviews (n=22), two post-workshop interviews (n=17), workshop observations (n=2), classroom observations (n=24) and student work (n=351). I used mixed-methods analysis. Quantitative analysis measured teacher learning by comparing pre and post-unit interview ratings. Qualitative components included two case study approaches: logic model technique and cross-case synthesis, examining teacher learning within and across teachers. The findings suggested a teacher-learning model incorporating PD, teacher knowledge, beliefs, practice and student response. PD impacts teachers' knowledge by providing teachers with new knowledge, adapting previous knowledge, or convincing them to value existing knowledge they chose not to use. The workshops can influence beliefs, providing teachers with confidence and motivation to adopt the practice. Beliefs can mediate how knowledge manifested itself in practice that, in turn, impacts students' response. Student response influences the teachers' beliefs, either reinforcing or motivating change. This teacher-learning model

Curricular review is considered a necessary component for growth and enhancement of academic programs and requires time, energy, creativity, and persistence from both faculty and administration. At Texas A&M College of Veterinary Medicine & Biomedical Sciences (TAMU), the faculty and administration partnered with the university's Center for Teaching Excellence to create a faculty-driven, data-enhanced curricular redesign process. The 8-step process begins with the formation of a dedicated faculty curriculum design team to drive the redesign process and to support the college curriculum committee. The next steps include defining graduate outcomes and mapping the current curriculum to identify gaps and redundancies across the curriculum. Data are collected from internal and external stakeholders including veterinary students, faculty, alumni, and employers of graduates. Data collected through curriculum mapping and stakeholder engagement substantiate the curriculum redesign. The guidelines, supporting documents, and 8-step process developed at TAMU are provided to assist other veterinary schools in successful curricular redesign. This is the first of a two-part report that provides the background, context, and description of the process for charting the course for curricular change. The process involves defining expected learning outcomes for new graduates, conducting a curriculum mapping exercise, and collecting stakeholder data for curricular evaluation (steps 1-4). The second part of the report describes the development of rubrics that were applied to the graduate learning outcomes (steps 5-8) and engagement of faculty during the implementation phases of data-driven curriculum change.

Dismantling the Curriculum in Higher Education

Directory of Open Access Journals (Sweden)

Richard Hall

2016-04-01

Full Text Available The higher education curriculum in the global North is increasingly co-opted for the production of measurable outcomes, framed by determinist narratives of employability and enterprise. Such co-option is immanent to processes of financialisation and marketisation, which encourage the production of quantifiable curriculum activities and tradable academic services. Yet the university is also affected by global socio-economic and socio-environmental crises, which can be expressed as a function of a broader crisis of social reproduction or sociability. As the labour of academics and students is increasingly driven by a commodity-valuation rooted in the measurement of performance, the ability for academics and students to respond to crises from inside the university is constrained by the market. This article argues that in understanding the relationship between the university and society, and in responding to a crisis of sociability, revealing the bounded nature of the curriculum is central. One possible way to address this crisis is by re-imagining the university through the co-operative practices of groups like the Dismantling the Masters House community and the Social Science Centre. Such an exploration, rooted in the organising principles of the curriculum, asks educators to consider how their curriculum reproduces an on-going colonisation by Capital. It is argued that such work enables a re-imagination of higher education that is rooted in a co-operative curriculum, and which might enable activist-educators to build an engaged curriculum, through which students and academics no longer simply learn to internalise, monitor and manage their own alienation.

2016-02-01

The principles of Collins' cognitive apprenticeship model were used to design a radiology curriculum in which medical students practice radiological skills using online case-based modules. The modules are embedded within clinical third-year clerkships, and students are provided with personalized feedback from the instructors. We describe the development of the vertical online radiology curriculum and evaluate its impact on student achievement and learning process using a mixed method approach. The curriculum was developed over a 2-year period. Student participation was voluntary in the first year and mandatory in the second year. For quantitative curriculum evaluation, student metrics for voluntary versus mandatory groups were assessed using independent sample t tests and variable entry method regression analysis. For qualitative analysis, responses from a survey of students about the value of the curriculum were organized into defined themes using consensus coding. Mandatory participation significantly improved (p = .001) the mean radiology examination score (82 %) compared to the voluntary group (73%), suggesting that mandatory participation had a beneficial effect on student performance. Potential preexisting differences in underlying general academic performance were accounted for by including mean basic science grades as the first variable in the regression model. The significant increase in R(2) from .16 to .28 when number of radiology cases completed was added to the original model, and the greater value of the standardized beta for this variable, suggest that the curriculum made a significant contribution to students' radiology examination scores beyond their baseline academic performance. Five dominant themes about curricular characteristics that enhanced student learning and beneficial outcomes emerged from consensus coding. These themes were (1) self-paced design, (2) receiving feedback from faculty, (3) clinical relevance of cases, (4) gaining

Various information systems for medical curriculum mapping and harmonization have been developed and successfully applied to date. However, the methods for exploiting the datasets captured inside the systems are rather lacking. We reviewed the existing medical terminologies, nomenclatures, coding and classification systems in order to select the most suitable one and apply it in delivering visual analytic tools and reports for the benefit of medical curriculum designers and innovators. A formal description of a particular curriculum of general medicine is based on 1347 learning units covering 7075 learning outcomes. Two data-analytical reports have been developed and discussed, showing how the curriculum is consistent with the MeSH thesaurus and how the MeSH thesaurus can be used to demonstrate interconnectivity of the curriculum through association analysis. Although the MeSH thesaurus is designed mainly to index medical literature and support searching through bibliographic databases, we have proved its use in medical curriculum mapping as being beneficial for curriculum designers and innovators. The presented approach can be followed wherever needed to identify all the mandatory components used for transparent and comprehensive overview of medical curriculum data.

Introduction: Antiretroviral pre-exposure prophylaxis (PrEP) for the prevention of HIV acquisition is cost-effective when delivered to those at substantial risk. Despite a high incidence of HIV infection among pregnant and breastfeeding women in sub-Saharan Africa (SSA), a theoretical increased risk of preterm birth on PrEP could outweigh the HIV prevention benefit. Methods: We developed a decision analytic model to evaluate a strategy of daily oral PrEP during pregnancy and breastfeeding in SSA. We approached the analysis from a health care system perspective across a lifetime time horizon. Model inputs were derived from existing literature and local sources. The incremental cost-effectiveness ratio (ICER) of PrEP versus no PrEP was calculated in 2015 U.S. dollars per disability-adjusted life year (DALY) averted. We evaluated the effect of uncertainty in baseline estimates through one-way and probabilistic sensitivity analyses. Results: PrEP administered to pregnant and breastfeeding women in SSA was cost-effective. In a base case of 10,000 women, the administration of PrEP averted 381 HIV infections but resulted in 779 more preterm births. PrEP was more costly per person ($450 versus $117), but resulted in fewer disability-adjusted life years (DALYs) (3.15 versus 3.49). The incremental cost-effectiveness ratio of $965/DALY averted was below the recommended regional threshold for cost-effectiveness of $6462/DALY. Probabilistic sensitivity analyses demonstrated robustness of the model. Conclusions: Providing PrEP to pregnant and breastfeeding women in SSA is likely cost-effective, although more data are needed about adherence and safety. For populations at high risk of HIV acquisition, PrEP may be considered as part of a broader combination HIV prevention strategy. PMID:27355502

Dmochowski, J. E.

2009-12-01

Recent restructuring of the University of Pennsylvania’s curriculum, including a revised multi-disciplinary Environmental Studies major and a proposed Environmental Science major has led to several changes, including a mandatory junior research seminar. Feedback from students indicates that a more structured curriculum has helped guide them through the multi-disciplinary Environmental Studies major. The addition of mandatory courses in Statistics, Geographical and Environmental Modeling, as well as Economics and Policy has ensured that students have important skills needed to succeed after graduation. We have compiled a curriculum objective matrix to clarify both the broad and focused objectives of our curriculum and how each course helps to fulfill these objectives. An important aspect of both majors is the Senior Thesis. The junior research seminar was recently revised to help students prepare for their thesis research. Topic selection, library research, data presentation, basic research methods, advisor identification, and funding options are discussed. Throughout the course, faculty from within the department lecture about their research and highlight opportunities for undergraduates. In one assignment, students are given a few types of datasets and asked to present the data and error analysis in various formats using different software (SPSS and Excel). The final paper was a research proposal outlining the student’s Senior Thesis. Based on both the university and instructor written course evaluations, students felt they benefited most from writing their senior thesis proposal; doing assignments on data analysis, library research and critical analysis; and the faculty research lectures. The lessons learned in restructuring this flexible major and providing a research seminar in the junior year may benefit other departments considering such changes.

According to the updated concept of oral microbiology, the School of Stomatology, Wuhan University, has carried out oral microbiology teaching reforms during the last 5 years. There was no lab curriculum before 2009 except for a theory course of oral microbiology. The school has implemented an innovative curriculum with oral medicine characteristics to strengthen understanding of knowledge, cultivate students' scientific interest and develop their potential, to cultivate the comprehensive ability of students. This study was designed to evaluate the oral microbiology lab curriculum by analyzing student performance and perceptions regarding the curriculum from 2009 to 2013. The lab curriculum adopted modalities for cooperative learning. Students collected dental plaque from each other and isolated the cariogenic bacteria with selective medium plates. Then they purified the enrichment culture medium and identified the cariogenic strains by Gram stain and biochemical tests. Both quantitative and qualitative data for 5 years were analysed in this study. Part One of the current study assessed student performance in the lab from 2009 to 2013. Part Two used qualitative means to assess students' perceptions by an open questionnaire. The 271 study students' grades on oral microbiology improved during the lab curriculum: "A" grades rose from 60.5 to 81.2 %, and "C" grades fell from 28.4 to 6.3 %. All students considered the lab curriculum to be interesting and helpful. Quantitative and qualitative data converge to suggest that the lab curriculum has strengthened students' grasp of important microbiology-related theory, cultivated their scientific interest, and developed their potential and comprehensive abilities. Our student performance and perception data support the continued use of the innovative teaching system. As an extension and complement of the theory course, the oral microbiology lab curriculum appears to improve the quality of oral medicine education and help to
