OBJECTIVE To investigate differences in HIV infection- related risk practices by Female Sex Workers according to workplace and the effects of homophily on estimating HIV prevalence. METHODS Data from 2,523 women, recruited using Respondent-Driven Sampling, were used for the study carried out in 10 Brazilian cities in 2008-2009. The study included female sex workers aged 18 and over. The questionnaire was completed by the subjects and included questions on characteristics of professional activity, sexual practices, use of drugs, HIV testing, and access to health services. HIV quick tests were conducted. The participants were classified in two groups according to place of work: on the street or indoor venues, like nightclubs and saunas. To compare variable distributions by place of work, we used Chi-square homogeneity tests, taking into consideration unequal selection probabilities as well as the structure of dependence between observations. We tested the effect of homophily by workplace on estimated HIV prevalence. RESULTS The highest HIV risk practices were associated with: working on the streets, lower socioeconomic status, low regular smear test coverage, higher levels of crack use and higher levels of syphilis serological scars as well as higher prevalence of HIV infection. The effect of homophily was higher among sex workers in indoor venues. However, it did not affect the estimated prevalence of HIV, even after using a post-stratification by workplace procedure. CONCLUSIONS The findings suggest that strategies should focus on extending access to, and utilization of, health services. Prevention policies should be specifically aimed at street workers. Regarding the application of Respondent-Driven Sampling, the sample should be sufficient to estimate transition probabilities, as the network develops more quickly among sex workers in indoor venues.

Best practice workplace HIV/AIDS programmes in South Africa: A review of case studies and lessons learned

PubMed Central

2009-01-01

ABSTRACT Background A group of experts attending a tripartite interregional meeting on best practices in HIV/AIDS workplace policies and programmes organised by the International Labour Organisation (ILO) in Geneva, Switzerland, identified 34 best practice workplace HIV programmes from across the world. Method The ten criteria that were used for reviewing best practice workplace HIV/AIDS programmes in South Africa include acceptability, accessibility, ethical soundness, perceived impact, relevance, appropriateness, innovativeness, efficiency, sustainability and replicability. Results More than one-third (35.3%) of the 34 best practice workplace interventions identified were found in businesses and industries in South Africa. This constitutes a significant and encouraging effort to deal with HIV/AIDS in the workplace. Approximately 16.7% of the best practice workplace HIV/AIDS interventions focused on policy and legal frameworks, 50% of these interventions focused on prevention, 16.7% provided links beyond the workplace and a further 16.7% were interventions that focused on knowledge and evidence. A third (33.3%) of practices were found in the mining industry, 16.7% in the motor industry, 16.7% from workers’ unions, and the rest (33.3%) were found in a sugar company, an electricity supply company, a pharmaceutical company and the ministry of Public Service and Administration. Conclusion It is encouraging that over one-third of all best practice workplace HIV interventions identified by the ILO experts were found in South Africa. The majority of these policies and programmes were focused on HIV prevention.

Despite demonstrating global concerns about infection in the workplace, very little research has explored how co-workers react to those living with HIV in the workplace in sub-Saharan Africa. This study aimed to assess the level of stigmatising attitude towards co-workers living with HIV in the workplace. The study was a descriptive cross-sectional survey involving 403 respondents. They were recruited from selected companies through a multistage sampling technique. Survey was carried out using pre-tested semi-structured questionnaires. Data were analyzed using the Statistical Package for the Social Sciences to generate frequencies, cross tabulations of variables at 5% level of significance. Logistic regression model was used to determine the predictors at 95% confidence intervals. Mean age of respondents was 32.9 ± 9.4 years with 86.1% being females. Overall, slightly below two-third (63.0%) had good knowledge on transmission of HIV/AIDS while 218 (54.1%) respondents had a high stigmatising attitude towards co-workers with HIV in the workplace. More female respondents (69.6%) demonstrated high stigmatising attitudes towards co-workers with HIV in the workplace (p = 0.012). Female workers were twice more likely to have high stigmatising attitudes towards co-worker with HIV [OR 2.1 (95% CI: 1.13 - 3.83)]. Stigma towards people living with HIV/AIDs is still very persistent in different settings. Good knowledge amongst our participants about HIV/AIDs did not translate to low stigmatising attitudes among workers. Concerted efforts and trainings on the transmission of HIV/AIDs are essential to reduce stigma that is still very prevalent in workplace settings.

Partner notification (PN) following sexually transmitted disease (STI) diagnosis is a key strategy for controlling HIV/STI transmission. Anonymous partnerships are an important barrier to PN and often associated with high-risk sexual behaviour. Limited research has examined the profile of men who have sex with men (MSM) and transgender women (TW) who engage in anonymous sex. To better understand anonymous partnership practices in Lima, Peru, we assessed participant-level and partnership-level characteristics associated with anonymous sex among a sample of MSM and TW recently diagnosed with HIV/STI. MSM and TW diagnosed with HIV/STI within the past month completed a cross-sectional survey regarding anticipated PN practices. Participants reported sexual partnership types and characteristics of up to three of their most recent partners. Using a Poisson generalised estimating equation model, we assessed participant-level and partnership-level characteristics associated with anonymous partnerships. Among 395 MSM and TW with HIV/STI, 36.0% reported at least one anonymous sexual partner in the past 3 months (mean of 8.6 anonymous partners per participant; SD 17.0). Of the 971 partnerships reported, 118 (12.2%) were anonymous and the majority (84.8%) were with male partners, followed by 11.0% with female partners and 4.2% with transgender/travesti partners. Partner-level characteristics associated with increased likelihood of having an anonymous partner included female (adjusted prevalence ratio (aPR) 2.28, 95% CI 1.05 to 4.95, p=0.04) or transgender/travesti (aPR 4.03, 95% CI 1.51 to 10.78, p=0.006) partner gender. By assessing both individual-level and dyadic-level factors, these results represent an important step in understanding the complexity of partnership interactions and developing alternative PN strategies for Latin America.

A study was undertaken of the views of users of two genitourinary medicine (GUM) clinics in England on unlinked anonymous testing (UAT) for HIV. The UAT programme measures the prevalence of HIV in the population, including undiagnosed prevalence, by testing residual blood (from samples taken for clinical purposes) which is anonymised and irreversibly unlinked from the source. 424 clinic users completed an anonymous questionnaire about their knowledge of, and attitudes towards, UAT. Only 1/7 (14%) were aware that blood left over from clinical testing may be tested anonymously for HIV. A large majority (89%) said they would agree to their blood being tested, although 74% wanted the opportunity to consent. These findings indicate broad support for UAT of blood in a group of patients whose samples are included in the HIV surveillance programme. The findings suggest the need for greater attention to be given to the provision of information and, if replicated in a larger survey, may justify a reappraisal of UK policy on UAT.

An estimated 14 % of the 1.2 million individuals living with HIV in the U.S. are unaware of their status. Yet this modest proportion of individuals with undiagnosed HIV is linked to 44-66 % of all new infections. Thus innovative intervention approaches are needed to seek out and test those with undiagnosed HIV, and link them to HIV treatment with high retention, an approach referred to as "Seek, Test, Treat, and Retain" (STTR). The present protocol describes a creative "hybrid" STTR approach that uses anonymous HIV testing followed by confidential care linkage, focused on heterosexuals at high risk (HHR) for HIV, who do not test as frequently as, and are diagnosed later, than other risk groups. This is a single-arm exploratory intervention efficacy trial. The study has two phases: one to seek out and test HHR, and another to link those found infected to HIV treatment in a timely fashion, with high retention. We will recruit African American/Black and Latino adult HHR who reside in urban locations with high poverty and HIV prevalence. Participants will be recruited with respondent-driven sampling, a peer recruitment method. The "Seek and Test" phase is comprised of a brief, convenient, single-session, anonymous HIV counseling and testing session. The "Treat and Retain" component will engage those newly diagnosed with HIV into a confidential research phase and use a set of procedures called care navigation to link them to HIV primary care. Participants will be followed for 6 months with objective assessment of outcomes (using medical records and biomarkers). Undiagnosed HIV infection is a major public health problem. While anonymous HIV testing is an important part of the HIV testing portfolio, it does not typically include linkage to care. The present study has potential to produce an innovative, brief, cost-effective, and replicable STTR intervention, and thereby reduce racial/ethnic disparities in HIV/AIDS.

Adoption of formal HIV and AIDS workplace policies: an analysis of industry/sector variations.

Bakuwa, Rhoda

2010-12-01

Addressing HIV and AIDS is the responsibility of many stakeholders including private sector companies. However, increasing evidence reveals that the majority of companies around the world are yet to acknowledge and respond to HIV and AIDS as a workplace issue. One factor that has been identified in the literature as playing a role in determining whether a company responds to HIV and AIDS, or not, is the industry/sector in which a company operates. This study therefore sought to empirically examine whether in the context of Malawi there were significant variations in the adoption of formal HIV and AIDS workplace policies based on the industry/sector in which a company was operating, as well as analyse the dynamics underlying such variations. Using survey data collected from 152 randomly selected private sector companies in Malawi, the results of this study revealed significant variations in the adoption of HIV and AIDS workplace policies among companies operating in various sectors. Companies in the service sector were leading the adoption compared to companies in other sectors such as the trading sector. Furthermore, the evidence from this study showed that differences in staff participation in the activities of HIV and AIDS institutions may explain the industry/sector variations. These results provide an important avenue to scale up company responses to HIV and AIDS by intensifying staff participation in the activities of HIV and AIDS institutions. Such institutions appear to play a vital role of providing up to date HIV-and AIDS-related information upon which companies are able to develop a business case for responding to the epidemic.

The aim of the study was to understand how lottery incentives influenced the HIV counselling and testing (HCT) behaviour and behaviour intention of shop-floor workers who participated in a workplace HCT campaign initiative in two companies in the Nelson Mandela Bay municipality, South Africa. A post-test only quasi-experimental approach was used. The data were first collected, using a self-administered cross-sectional survey instrument, among the control group (n = 88) followed by the experimental group (n = 110) after the advent of HIV testing and lotteries was announced. HIV testing behaviour data were collected on the days of the HIV testing events. The theory of planned behaviour (TPB) was used as guiding theory. Principal component analysis (PCA), t- and chi-square tests, and logistic regression were conducted to analyse the data. A significant increase in the mean scores of the experimental as compared to the control condition for the subjective norm's construct (t = -3.55, p < 0.001) and HIV testing behaviour intention (χ 2 = 12.35, p < 0.001) was measured following the announcement of lottery incentives. The constructs of TPB explained 40% of the variance in HCT behaviour intention (R 2 = 0.40). The strongest predictor of behaviour intention was the subjective norm (B = 0.435 and p < 0.001), followed by the attitudinal component (B = 0.323 and p = 0.040). The announcement of lotteries made shop-floor workers develop a stronger intention to participate in workplace HIV testing through anticipation of stronger social support and encouragement. It was not possible to link behaviour intention to behaviour due to missing data. The findings point to the importance of providing workers with an opportunity to openly discuss HIV testing thus allowing mitigation of HIV stigma and discrimination and permitting HIV testing to become socially sanctioned and seen as part of a collective effort.

The services of general interest provided by hospitals, such as free HIV clinics, have been funded since 2005 by a lump sum covering all costs. The allocation of the budget was initially determined based on historical and declarative data. However, the French Ministry of Health (MoH) recently outlined new rules for determining the allocation of financial resources and contracting hospitals for each type of services of general interest provided. The aim of this study was to estimate the annual cost of a public free anonymous HIV-testing center and to assess the budgetary implications of new financing systems. Three financing options were compared: the historic block grant; a mixed system recommended by the MoH associating a lump sum covering the recurring costs of an average center and a variable part based on the type and volume of services provided; and a fee-for-services system. For the purposes of this retrospective study, the costs and activity data of the HIV testing clinic of a public hospital located in the North of Paris were obtained for 2007. The costs were analyzed from the perspective of the hospital. The total cost was estimated at 555,698 euros. Personnel costs accounted for 31% of the total costs, while laboratory expenses accounted for 36% of the total costs. While the estimated deficit was 292,553 euros under the historic system, the financial balance of the clinic was found to be positive under a fee-for-services system. The budget allocated to the HIV clinic under the system recommended by the MoH covers most of the current expenses of the HIV clinic while meeting the requirements of free confidential care.

In a study of female sex workers (FSW) servicing truck driver clients in Mexican border cities, we evaluated differences in HIV/STI risk behaviors by workplace. Cross-sectional study of FSW servicing truck drivers in Mexico: 100 from Nuevo Laredo (U.S. border); 100 from Ciudad Hidalgo (Guatemalan border). Main outcome was unstable workplace, defined as primary place of sex work in a public place (street, vehicle, gas station, etc.) vs. stable workplace (bar, brothel, and hotel). Logistic regression was used to identify correlates associated with trading sex at unstable workplaces in the last month. Of the FSW surveyed, 18% reported an unstable workplace. The majority of FSW surveyed were young (<30), single, had <9 th grade education, and had worked in the sex trade for a median of 4.9 years. After controlling for study site, FSW with unstable vs. stable workplaces were more likely to have a majority/all truck driver clientele, but were less likely to have visited a gynecologist in the last year (OR 0.1, 95%CI 0.03-0.4) or ever had an HIV test (OR 0.1, 95%CI 0.06-0.3), and there was a trend towards lower condom use self-efficacy scores (OR 0.8 per unit increase, 95%CI 0.7-1.0). On multivariate regression, unstable workplace was associated with having majority/all truck driver clientele, being surveyed in Nuevo Laredo, and decreased odds of ever having an HIV test. Among Mexican FSW with truck driver clients, providing safe indoor spaces for sex work may help facilitate public health interventions that improve HIV/STI and reproductive health outcomes.

The article contextualises an emerging new regime for information privacy in South Africa (i.e. the draft Protection of Personal Information Bill). Subsequently, it discusses the possibility of successful implementation of international data-protection standards in an environment where there is an urgent need to balance HIV/AIDS confidentiality rights with public health requirements. Also, the article presents a preliminary assessment of the possible impact of professionalisation (and outsourcing) of workplace HIV/AIDS management on workplace data-protection practices, and it identifies some spaces for social dialogue on HIV/AIDS-data treatment in South Africa. The study methods comprise an analysis of legal documents (concerning international data-protection standards and the development of law governing data protection and HIV/AIDS confidentiality in South Africa) and interviews conducted with workplace health managers and trade union representatives, in Johannesburg, in 2007.

2014-01-01

Abstract Despite South African mid-sized companies' efforts to offer HIV counselling and testing (HCT) in the workplace, companies report relatively poor uptake rates. An urgent need for a range of different interventions aimed at increasing participation in workplace HCT has been identified. The aim of this study was to explore qualitatively the influence of a lottery incentive system (LIS) as an intervention to influence shop-floor workers' workplace HIV testing behaviour. A qualitative study was conducted among 17 shop-floor workers via convenience sampling in two mid-sized South African automotive manufacturing companies in which an LIS for HCT was implemented. The in-depth interviews employed a semi-structured interview schedule and thematic analysis was used to analyse the data. The interviews revealed that the LIS created excitement in the companies and renewed employees' personal interest in HCT. The excitement facilitated social interactions that resulted in a strong group cohesion pertaining to HCT that mitigated the burden of HIV stigma in the workplace. Open discussions allowed for the development of supportive social group pressure to seek HCT as a collective in anticipation of a reward. Lotteries were perceived as a supportive and innovative company approach to workplace HCT. The study identified important aspects for consideration by companies when using an LIS to enhance workplace HIV testing. The significance of inter- and intra-player dialogue in activating supportive social norms for HIV testing in collectivist African contexts was highlighted. PMID:25023208

The health service sector has a vital role to play in delivering human immunodeficiency virus (HIV) and tuberculosis (TB) prevention, treatment and care, yet evidence indicates that healthcare workers (HCWs) themselves lack adequate access to HIV and TB services. HCWs are also at increased risk from TB and other infectious diseases at work, and therefore accessing HIV services is particularly important. A systematic review was therefore conducted to inform the development of World Health Organization (WHO) guidelines to improve access to HIV and TB services, and specifically, to assess the evidence regarding providing such services through workplace-based programmes. We identified any study published since 1984 that addressed outcomes of interest as defined through multi-stakeholder consultations, and were related to workplace interventions in (1) the healthcare workplace and (2) any workplace that included HIV and/or TB diagnosis and/or treatment. Interventions focusing solely on primary prevention with no diagnostic or treatment services were excluded, as they were the subject of other guidelines. A minimum of two reviewers independently extracted data and assessed the articles against pre-set selection criteria; studies were also profiled and quality assessed by a minimum of two reviewers. Three studies met these criteria specifically for HCWs; all showed a preponderance of positive benefits, with minimal negative outcome. Seven studies met these criteria regarding workplace HIV and/or TB diagnosis and/or treatment from other sectors, public or private. Again, all showed positive results. The paucity of high-quality evidence in this field of research was itself an important finding, beckoning further research on workplace-based programmes for health workers. Nonetheless, while more well-designed intervention studies are definitely desirable, providing programmes for HCWs to obtain HIV and TB diagnosis and treatment at the workplace is supported by the literature

This study aimed to evaluate the effectiveness of an HIV workplace programme in sub-Saharan Africa. The international brewing company, Heineken, introduced an HIV workplace programme in its African subsidiaries in 2001. Beneficiaries from 16 sites in 5 countries were eligible. HIV type-1 (HIV-1)-infected individuals were assessed clinically and immunologically, and started highly active antiretroviral therapy (HAART) if they had AIDS or had a CD4+ T-cell count <300 cells/microl. In this cohort, study patients were followed-up for vital status, new AIDS events, CD4+ T-cell count and haemoglobin. Over the first 5 years of the programme, 431 adults were found to be HIV-1-infected. The mortality rate among those not yet taking HAART was 2.6 per 100 person-years of observation (pyo). By October 2006, 249 patients had started HAART at a median CD4+ T-cell count of 170 cells/microl; 59 (23.7%) patients were in CDC stage C. Among patients on HAART, 25 died and 7 were lost to follow-up. The mortality rate was 3.7 per 100 pyo overall, 14 per 100 pyo in the first 16 weeks and 2.5 per 100 pyo thereafter (P < 0.0001). At 4 years after start of treatment, 89% of patients were known to be alive. The CD4+ T-cell count increased by a median of 153 and 238 cells/microl after 1 and 4 years of HAART, respectively. In this HIV workplace programme in sub-Saharan Africa, long-term high survival was achieved.

Vulnerability to Human Immunodeficiency Virus (HIV) infection among factory workers is a global problem. This study investigated the effectiveness of an intervention to increase AIDS knowledge, perceived accessibility to condoms and condom use among young factory workers in Thailand. The intervention was a workplace program designed to engage the private sector in HIV prevention. A cross-sectional survey conducted in 2008 to measure program outcomes in factories in Thailand was used in this study. The workplace intervention included the development of policies for management of HIV-positive employees, training sessions for managers and workers, and distribution of educational materials and condoms. A multi-level analysis was used to investigate the effect of HIV/AIDS prevention program components at the workplace on HIV/AIDS knowledge, perceived accessibility to condoms and condom use with regular sexual partners among 699 young factory workers (aged 18-24 years), controlling for their individual socio-demographic characteristics. Interventions related to the management and services component including workplace AIDS policy formulation, condom services programs and behavioral change campaigns were found to be significantly related to increased AIDS knowledge, perceived accessibility to condoms and condom use with regular partners. The effect of the HIV/AIDS training for managers, peer leaders and workers was positive but not statistically significant. With some revision of program components, scaling up of workplace interventions and the engagement of the private sector in HIV prevention should be seriously considered.

Drawing from previous research on individual differences, AIDS, and concerns for face, the author developed and tested a model examining the predictors (knowledge of AIDS transmission, level of homophobia, and concern for face) of AIDS fear and its organizational outcomes (perceived organizational consequences of hiring people living with HIV and attitudes toward disclosure of HIV-related information at the workplace). Data were collected using mail survey. Structural equation modeling was used to examine the relationships among these variables for 160 human resource managers. All of the hypothesized relationships were empirically supported. Implications of the research findings for human resource practices are discussed. 2003 APA

Background HIV counselling and testing is a key component of both HIV care and HIV prevention, but uptake is currently low. We investigated the impact of rapid HIV testing at the workplace on uptake of voluntary counselling and testing (VCT). Methods and Findings The study was a cluster-randomised trial of two VCT strategies, with business occupational health clinics as the unit of randomisation. VCT was directly offered to all employees, followed by 2 y of open access to VCT and basic HIV care. Businesses were randomised to either on-site rapid HIV testing at their occupational clinic (11 businesses) or to vouchers for off-site VCT at a chain of free-standing centres also using rapid tests (11 businesses). Baseline anonymised HIV serology was requested from all employees. HIV prevalence was 19.8% and 18.4%, respectively, at businesses randomised to on-site and off-site VCT. In total, 1,957 of 3,950 employees at clinics randomised to on-site testing had VCT (mean uptake by site 51.1%) compared to 586 of 3,532 employees taking vouchers at clinics randomised to off-site testing (mean uptake by site 19.2%). The risk ratio for on-site VCT compared to voucher uptake was 2.8 (95% confidence interval 1.8 to 3.8) after adjustment for potential confounders. Only 125 employees (mean uptake by site 4.3%) reported using their voucher, so that the true adjusted risk ratio for on-site compared to off-site VCT may have been as high as 12.5 (95% confidence interval 8.2 to 16.8). Conclusions High-impact VCT strategies are urgently needed to maximise HIV prevention and access to care in Africa. VCT at the workplace offers the potential for high uptake when offered on-site and linked to basic HIV care. Convenience and accessibility appear to have critical roles in the acceptability of community-based VCT. PMID:16796402

Abstract We investigated reasons for clinical follow-up and treatment discontinuation among HIV-infected individuals receiving antiretroviral therapy (ART) in a public-sector clinic and in a workplace clinic in South Africa. Participants in a larger cohort study who had discontinued clinical care by the seventh month of treatment were traced using previously provided locator information. Those located were administered a semistructured questionnaire regarding reasons for discontinuing clinical follow-up. Participants who had discontinued antiretroviral therapy were invited to participate in further in-depth qualitative interviews. Fifty-one of 144 (35.4%) in the workplace cohort had discontinued clinical follow-up by the seventh month of treatment. The median age of those who discontinued follow-up was 46 years and median educational level was five years. By contrast, only 16.5% (44/267) of the public-sector cohort had discontinued follow-up. Among them the median age was 37.5 years and median education was 11 years. Qualitative interviews were conducted with 17 workplace participants and 10 public-sector participants. The main reasons for attrition in the workplace were uncertainty about own HIV status and above the value of ART, poor patient–provider relationships and workplace discrimination. In the public sector, these were moving away and having no money for clinic transport. In the workplace, efforts to minimize the time between testing and treatment initiation should be balanced with the need to provide adequate baseline counseling taking into account existing concepts about HIV and ART. In the public sector, earlier diagnosis and ART initiation may help to reduce early mortality, while links to government grants may reduce attrition. PMID:21214378

Stigma is commonly experienced by people living with HIV/AIDS and by those providing care to HIV/AIDS patients. Few intervention studies have explored the impact of workplace policies and/or quality improvement on stigma. We examine the contribution of health care workplace policies, procedures and quality assurance initiatives, and self- and peer-assessed individual nurse practices, to nurse-reported HIV/AIDS-stigma practices toward patients living with HIV/AIDS and nurses in health care settings. Our sample of survey respondents (n = 1157) included managers (n = 392) and registered/enrolled nurses (n = 765) from 29 facilities in 4 countries (South Africa, Uganda, Jamaica, Kenya). This is one of the first studies in LMIC countries to use hierarchical linear modeling to examine the contributions of organizational and individual factors to HIV/AIDS stigma. Based on our results, we argue that organizational interventions explicitly targeting HIV/AIDS stigma are required to reduce the incidence, prevalence and morbidity of HIV/AIDS.

Consultation on AIDS and the workplace.

PubMed

1988-12-01

The 1988 Consultation on Acquired Immunodeficiency Syndrome (AIDS) and the Workplace, organized by the World Health Organization (WHO), addressed 3 issues: 1) risk factors associated with human immunodeficiency virus (HIV) infection in the workplace, 2) the response of businesses and workers to the AIDS epidemic, and 3) use of the workplace for AIDS education. There is no evidence to suggest that HIV can be transmitted by casual, person-to-person contact in the workplace. The central policy issue for businesses concerns protection of the human rights of workers with HIV infection. Most workers with HIV/AIDS want to continue working as long as they are able to, and they should be enabled to contribute their creativity and productivity in a supportive occupational setting. Consistent policies and procedures should be developed at national and enterprise levels before HIV-related questions arise in the workplace. Such policies should be communicated to all concerned, continually reviewed in the light of scientific and epidemiologic evidence, monitored for their successful implementation, and evaluated for their effectiveness. Pre-employment HIV/AIDS screening, whether for assessment of fitness to work or for insurance purposes, should not be required and raises serious concerns about discrimination. Moreover, there should be no obligation on the worker's part to inform his or her employer if HIV infection develops. Information and educational activities at the workplace are essential to create the climate of collective responsibility and mutual understanding required to protect individuals with HIV or AIDS from stigmatization and discrimination by co-workers, employers or clients, and unions.

Anonymous oocyte donation in the EU proceeds only after rigorous screening designed to ensure gamete safety. If anonymous donor gametes originating from outside EU territory are used by EU patients, donor testing must conform to the same standards as if gamete procurement had occurred in the EU. In Ireland, IVF recipients can be matched to anonymous donors in the Ukraine (a non-EU country). This investigation describes the evolution of anonymous oocyte donor screening methods during this period and associated results. Data were reviewed for all participants in an anonymous donor oocyte IVF programme from 2006 to 2009, when testing consistent with contemporary EU screening requirements was performed on all Ukrainian oocyte donors. HIV and hepatitis tests were aggregated from 314 anonymous oocyte donors and 265 recipients. The results included 5,524 Ukrainian women who were interviewed and 314 of these entered the programme (5.7% accession rate). Mean age of anonymous oocyte donors was 27.9 years; all had achieved at least one delivery. No case of hepatitis or HIV was detected at initial screening or at oocyte procurement. This is the first study of HIV and hepatitis incidence specifically among Ukrainian oocyte donors. We find anonymous oocyte donors to be a low-risk group, despite a high background HIV rate. Following full disclosure of the donation process, most Ukrainian women wishing to volunteer as anonymous oocyte donors do not participate. Current EU screening requirements appear adequate to maintain patient safety in the context of anonymous donor oocyte IVF.

How did rapid scale-up of HIV services impact on workplace and interpersonal trust in Zambian primary health centres: a case-based health systems analysis

Background In sub-Saharan Africa, large amounts of funding continue to be directed towards HIV-specific care and treatment, often with claims of ‘health system strengthening’ effect. Such claims rarely account for the impact on human relationships and decisions that are core to functional health systems. This research examined how establishment of externally funded HIV services influenced trusting relationships in Zambian health centres. Methods An in-depth, multicase study included four health centres selected for urban, peri-urban and rural characteristics. Case data included healthcare worker (HCW) interviews (60); patient interviews (180); direct observation of facility operations (2 weeks/centre) and key informant interviews (14) which were recorded and transcribed verbatim. Thematic analysis adopted inductive and deductive coding guided by a framework incorporating concepts of workplace trust, patient–provider trust, intrinsic and extrinsic motivation. Results HIV service scale-up impacted trust in positive and negative ways. Investment in HIV-specific infrastructure, supplies and quality assurance mechanisms strengthened workplace trust, HCW motivation and patient–provider trust in HIV departments in the short-term. In the health centres more broadly and over time, however, non-governmental organisation-led investment and support of HIV departments reinforced HCW's perceptions of the government as uninterested or unable to provide a quality work environment. Exacerbating existing perceptions of systemic workplace inequity and nepotism, uneven distribution of personal and professional opportunities related to HIV service establishment contributed to interdepartmental antagonism and reinforced workplace practices designed to protect individual HCW's interests. Conclusions Findings illustrate long-term negative effects of the vertical HIV resourcing and support structures which failed to address and sometimes exacerbated HCW (dis)trust with their own

The International Committee of the Red Cross (ICRC) works in fragile States and in armed conflict zones. Some of them are affected by the HIV pandemic. Within the framework of its social responsibility programme concerning HIV affecting its staff members, the organization has implemented an HIV workplace programme since 2004. We carried out a retrospective analysis over 10 years. Data collected were initially essentially qualitative and process-oriented, but were complemented over the years by data on annual voluntary counselling and testing (VCT) uptake and on direct annual costs covering awareness, testing and antiretroviral therapy. The number of people covered by the programme grew from none in 2003 to 4,438 in 2015, with an increase in annual VCT uptake over the years increasing from 376 persons (14 %) in 2007 to 2,663 in 2015 (60 %). Over the years, the services were expanded from awareness raising to bringing VCT to the workplace, as well as offering testing and health coverage of other conditions and innovative approaches to facing challenges linked to situations of violence. Within its social responsibility framework, the ICRC has shown the importance and feasibility of a workplace HIV programme in conflict zones. A sustainable workplace programme in these conflict settings requires constant adaptation, with regular follow-up given the relatively high turnover of staff, and ensuring sustainable stocks of condoms and antiretroviral drugs.

The onset of HIV/AIDS has increased stigma and discrimination at workplaces, making those with these ailments worried about going to work to avoid being victimized. Most previous works focussed on stigma and discrimination in the communities with little emphasis on what occurs in the workplaces. This study assessed the prevalence of workplace stigma and discrimination among people living with HIV/AIDS (PLWHA) attending antiretroviral (ARV) clinics in health institutions in Enugu, southeast Nigeria. A cross-sectional descriptive study was done between February and May of 2014 using a selfadministered questionnaire to assess 489 PLWHA attending ARV clinics. Out of 489 studied, 255 (52.1%) were females. About 23.7% said being HIV positive had affected their relationship with other workers and 20.7% were blamed for their condition. Some were not given time off to go to hospital (72.5%). The commonest fears of PLWHA were stigmatization/discrimination from other workers (78.1%) and dying from the disease (62.8%). Gender did not significantly affect the way PLWHA were stigmatized or discriminated against in their workplaces. However, those who were employed in private establishments were more likely to have their schedule changed due to their status compared to government employees ( p < 0.01). Other discriminating practices were not significantly different between government and private employees. The prevalence of stigma and discrimination in workplaces is high. Efforts should be made by agencies to reduce such social problems in the workplace since they can affect overall management and productivity.

HIV/AIDS stigma at the workplace: exploratory findings from Pakistan.

PubMed

Bashir, Sajid

2011-01-01

People living with HIV/AIDS (PLHA) are stigmatised socially. They are devalued and considered like outcasts by having lesser opportunities for education, treatment and housing, and in an organisational context they get reduced opportunities of selection, promotion and income. The phenomena have been extensively researched in developed countries but limited literature addresses the situation in underdeveloped countries like Pakistan, which is also facing spread of the HIV/AIDS epidemic. There are a number of groups who are carrying the disease but the problems being faced by PLHA employed in different organisations have rarely been analysed. Stigma at the workplace can generate a number of negative outcomes. The present study considers two such outcomes among stigmatised PLHA. These outcomes are organisational cynicism and breach of psychological contract. A questionnaire was used to collect data from a sample of 174 PLHA, having a work experience after identification of the epidemic, working in different organisations across Pakistan. These PLHA were identified and recruited through a scattered record available with some government/non-government organisations operating in Pakistan to control HIV/AIDS. Findings of the study extend the knowledge about HIV/AIDS stigma indicating that PLHA are subjected to stigma, which is significantly associated with a breach of psychological contract and organisational cynicism. There is a need at governmental and organisational level as well to increase awareness about the disease and formulate policies to reduce stigma against PLHA working in different organisations.

Data from 1,543 female migrants working in eight occupational clusters in Beijing and Nanjing, China were analysed to examine the association of workplace with HIV-related behaviours and perceptions. For sexually experienced women (n = 666, 43.2%), those working in entertainment establishments or personal service (e.g., nightclubs, dancing halls, barbershops, beauty salons, massage parlours, etc.) engaged in risky sexual practices twice as frequently as those working in non-entertainment establishments (e.g. restaurants, stalls, domestic service, factories, etc.). About 10% of women in the entertainment establishments reported having sold sex, 30% having multiple sexual partners and 40% having sex with men with multiple sexual partners. The rate of consistent condom use was less than 15%. They also tended to have a higher level of perceptions of both peer risk involvement and positive expectancy of risk behaviours, and lower perceptions of severity of STDs and HIV. For women who were not sexually experienced, those working in 'stalls' or 'domestic service' tended to perceive higher peer risk involvement, less severity of HIV infection, and less effectiveness of protective behaviour. The occupational pattern of sexual risk behaviours and perceptions observed in the current study indicates employment conditions are associated with HIV risk. Intervention strategies should be tailored to address occupational-related factors.

Stutterheim, Sarah E; Brands, Ronald; Baas, Ineke; Lechner, Lilian; Kok, Gerjo; Bos, Arjan E R

We explored workplace experiences of 10 health care providers with HIV in the Netherlands. We used semi-structured interviews to discuss motivations for disclosure and concealment, reactions to disclosures, the impact of reactions, and coping with negative reactions. Reasons for disclosure were wanting to share the secret, expecting positive responses, observing positive reactions to others, wanting to prevent negative reactions, and being advised to disclose. Reasons for concealment included fearing negative reactions, observing negative reactions, previous negative experiences, having been advised to conceal, and considering disclosure unnecessary. Positive reactions included seeing HIV as a nonissue; showing interest, support, and empathy; and maintaining confidentiality. Negative reactions included management wanting to inform employees, work restrictions, hiring difficulties, gossip, and hurtful comments, resulting in participants being upset, taken aback, angry, depressed, or feeling resignation. Participants coped by providing information, standing above the experience, attributing reactions to ignorance, seeking social support, or leaving their jobs.

Employment discrimination and HIV stigma: survey results from civil society organisations and people living with HIV in Africa.

2011-01-01

The article presents findings from three surveys of people living with HIV (PLHIV) and civil society organisations about the experience of employment discrimination and stigma in the workplace. The work seeks to contribute to efforts by businesses and other organisations to effectively respond to the HIV epidemic within the world of work, and to deepen our understanding of the ways in which HIV stigma and employment discrimination persist in the workplace. The findings of global and regional surveys indicate the existence of high levels of employment discrimination based on HIV status worldwide, including forced disclosure of HIV status, exclusion in the workplace, refusals to hire or promote, and terminations of people known to be living with HIV. The survey findings show that employment discrimination based on HIV status is experienced in all African subregions. Country-level surveys conducted in Kenya and Zambia indicated that PLHIV face marked barriers to employment, including discrimination in hiring, loss of promotions, and termination because of HIV status. Additionally, large variances were found in the degree of support versus discrimination that employees living with HIV in those two countries received following their disclosure. The discussion emphasises the importance of the workplace as a site for intervention and behaviour change. To address this, we introduce a conceptual framework - the employment continuum - that maps multiple points of entry within the workplace to address HIV-related stigma and discrimination. Additional recommendations include: actions to ensure equal opportunity in hiring for PLHIV; ensuring that HIV testing is voluntary, never mandatory, and that disclosure is not necessary for employment; ensuring confidentiality of HIV status; communicating and enforcing HIV-related antidiscrimination policies; establishing support groups in the workplace; providing safe and confidential processes for resolving complaints of employment

Guidelines for safe gamete donation have emphasised donor screening, although none exist specifically for testing oocyte recipients. Pre-treatment assessment of anonymous donor oocyte IVF treatment in Ireland must comply with the European Union Tissues and Cells Directive (Directive 2004/23/EC). To determine the effectiveness of this Directive when applied to anonymous oocyte recipients in IVF, we reviewed data derived from selected screening tests performed in this clinical setting. Data from tests conducted at baseline for all women enrolling as recipients (n = 225) in the anonymous oocyte donor IVF programme at an urban IVF referral centre during a 24-month period were analysed. Patient age at programme entry and clinical pregnancy rate were also tabulated. All recipients had at least one prior negative test for HIV, Hepatitis B/C, chlamydia, gonorrhoea and syphilis performed by her GP or other primary care provider before reproductive endocrinology consultation. Mean (±SD) age for donor egg IVF recipients was 40.7 ± 4.2 yrs. No baseline positive chlamydia, gonorrhoea or syphilis screening results were identified among recipients for anonymous oocyte donation IVF during the assessment interval. Mean pregnancy rate (per embryo transfer) in this group was 50.5%. When tests for HIV, Hepatitis B/C, chlamydia, gonorrhoea and syphilis already have been confirmed to be negative before starting the anonymous donor oocyte IVF sequence, additional (repeat) testing on the recipient contributes no new clinical information that would influence treatment in this setting. Patient safety does not appear to be enhanced by application of Directive 2004/23/EC to recipients of anonymous donor oocyte IVF treatment. Given the absence of evidence to quantify risk, this practice is difficult to justify when applied to this low-risk population.

To analyze HIV/AIDS positive individual's perception and attitudes regarding dental services. One hundred and thirty-four subjects (30.0% of women and 70.0% of men) from Nuevo León, Mexico, took part in the study (2014). They filled out structured, analytical, self-administered, anonymous questionnaires. Besides the sociodemographic variables, the perception regarding public and private dental services and related professionals was evaluated, as well as the perceived stigma associated with HIV/AIDS, through a Likert-type scale. The statistical evaluation included a factorial and a non-hierarchical cluster analysis. Social inequalities were found regarding the search for public and private dental professionals and services. Most subjects reported omitting their HIV serodiagnosis and agreed that dentists must be trained and qualified to treat patients with HIV/AIDS. The factorial analysis revealed two elements: experiences of stigma and discrimination in dental appointments and feelings of concern regarding the attitudes of professionals or their teams concerning patients' HIV serodiagnosis. The cluster analysis identified three groups: users who have not experienced stigma or discrimination (85.0%); the ones who have not had those experiences, but feel somewhat concerned (12.7%); and the ones who underwent stigma and discrimination and feel concerned (2.3%). We observed a low percentage of stigma and discrimination in dental appointments; however, most HIV/AIDS patients do not reveal their serodiagnosis to dentists out of fear of being rejected. Such fact implies a workplace hazard to dental professionals, but especially to the very own health of HIV/AIDS patients, as dentists will not be able to provide them a proper clinical and pharmaceutical treatment.

Social and psychological barriers to the disclosure of one's seropositive HIV status to significant others and poor adherence to taking medications pose significant challenges to the scaling-up of access to antiretroviral treatment (ART) in the workplace. Such barriers are predictive of sub-optimal treatment outcomes and bedevil HIV-prevention interventions at a societal level. Against this background, this article explores the lived experiences of 19 HIV-positive male participants, between the ages of 33 and 57 years, who were enrolled in an ART programme managed at an occupational health clinic at a mining company in South Africa. The majority of these mineworkers had been aware of their HIV status for between 5 and 7 years. The study explored psychological and relational factors, as aspects of these participants lived experiences, which had a bearing on their adherence to their ART regimen and the disclosure choices that they made regarding their HIV status. In our sample, those participants who were adherent demonstrated higher levels of control and acceptance of their HIV infection and were more confident in their ability to manage their treatment, while the group who were non-adherent presented with lower levels of adherence motivation and self-efficacy, difficulties in maintaining a healthy lifestyle and significant challenges in maintaining control over their lives. While most of the men favoured disclosing their HIV status to their partners for the sake of treatment support, they were less sure about disclosing to family members and non-family members, respectively, because of their need to protect these persons and due to their fear of being stigmatised. It was evident that treatment adherence choices and behaviours were impacted by psychological and relational factors, including disclosure decisions. We conclude with a bivariate model for understanding the adherence behaviours that influenced different patterns of ART adherence among the sample, and

The need for reliable epidemiological data on HIV seropositivity rates in a general population appears to conflict with the ethical requirement that consent be obtained from persons whose blood is screened for HIV antibodies. Gillet contends that informed consent is not necessary for epidemiological screening since there is no reason to link blood samples and test results with identifiable individuals. He argues that it is ethical to test blood drawn from hospital patients who have given a very general and "non-informative sort of consent" that their blood can be used anonymously for research. Even this degree of consent may be unnecessary since it would be impossible to trace an HIV positive anonymous blood sample to its source. Gillet also argues that this method of obtaining samples relieves epidemiologists of the obligation to notify individuals whose blood tests positive for HIV.

Information on the potential costs of HIV/AIDS to the private sector is needed if companies are to be given a financial incentive to invest in prevention and treatment interventions. To estimate the cost of HIV/AIDS to businesses in southern Africa using company-specific data on employees, costs, and HIV prevalence. : Six formal sector enterprises in South Africa and Botswana provided detailed human resource, financial, and medical data and carried out voluntary, anonymous HIV seroprevalence surveys. The present value of incident HIV infections with a 9-year median survival and 7% real discount rate was estimated. Costs included were sick leave; productivity loss; supervisory time; retirement, death, disability, and medical benefits; and recruitment and training of replacement workers. HIV prevalence in the workforces studied ranged from 7.9 to 25.0%. HIV/AIDS among employees added 0.4-5.9% to the companies' annual salary and wage bills. The present value of an incident HIV infection ranged from 0.5 to 3.6 times the annual salary of the affected worker. Costs varied widely across firms and among job levels within firms. Key reasons for the differences included HIV prevalence, levels and stability of employee benefits, and the contractual status of unskilled workers. Some costs were omitted from the analysis because of lack of data, and results should be regarded as quite conservative. AIDS is causing labor costs for businesses in southern Africa to rise and threatens the competitiveness of African industry. Research on the effectiveness of workplace interventions is urgently needed.

Comments on ``Anonymous Reviews'' An Editor's View of Anonymous Reviews

NASA Astrophysics Data System (ADS)

Goff, John A.

I have read with great interest the recent Forum commentaries in Eos by Myrl Beck, Charles Robinove, Robert Criss, and Anne Hofmeister regarding anonymous reviews. I heartily support their position that anonymous reviews should be avoided. I have not written an anonymous review in ages (and regret the few that I did), and have always appreciated and respected greatly anyone who signs a critical review of one of my own papers. However, I would like to add some perspective from the editorial standpoint. I have served as JGR associate editor for 3 years (never anonymously!), and as Eos editor for seismology and tectonophysics for 4. Over the years, I have rejected a fair number of papers, most of those based on anonymous reviews (fortunately, none of the above commentators was one of them). The vast majority of anonymous reviews I received were well considered. While I would wish that all reviews were signed, I don't think we can summarily dismiss the fear that many would have of enmity and reprisal over a critical review. Some of these fears are likely justified. On more than one occasion, have I witnessed overly aggressive responses on the part of authors to anonymous reviews that I considered to be entirely fair and constructive in their criticisms. I do think we need to do all we can to discourage anonymous reviews, but it will be difficult to completely remove that choice from the process.

Anonymous ranking is a kind of privacy-preserving ranking whereby each of the involved participants can correctly and anonymously get the rankings of his data. It can be utilized to solve many practical problems, such as anonymously ranking the students' exam scores. We investigate the issue of how quantum mechanics can be of use in maintaining the anonymity of the participants in multiparty ranking and present a series of quantum anonymous multiparty, multidata ranking protocols. In each of these protocols, a participant can get the correct rankings of his data and nobody else can match the identity to his data. Furthermore, the security of these protocols with respect to different kinds of attacks is proved.

Anonymity in Voting Revisited

NASA Astrophysics Data System (ADS)

Jonker, Hugo; Pieters, Wolter

According to international law, anonymity of the voter is a fundamental precondition for democratic elections. In electronic voting, several aspects of voter anonymity have been identified. In this paper, we re-examine anonymity with respect to voting, and generalise existing notions of anonymity in e-voting. First, we identify and categorise the types of attack that can be a threat to anonymity of the voter, including different types of vote buying and coercion. This analysis leads to a categorisation of anonymity in voting in terms of a) the strength of the anonymity achieved and b) the extent of interaction between voter and attacker. Some of the combinations, including weak and strong receipt-freeness, are formalised in epistemic logic.

Disease severity, self-reported experience of workplace discrimination and employment loss during the course of chronic HIV disease: differences according to gender and education.

PubMed

Dray-Spira, R; Gueguen, A; Lert, F

2008-02-01

Evidence for the existence of a harmful effect of chronic disease on employment status has been provided. Although this effect of chronic illness on employment has been reported to be higher among the groups with the lowest position on the labour market, the mechanisms of such inequalities are poorly understood. The present study aimed at investigating social inequalities in the chances of maintaining employment during the course of HIV infection and at examining the correlates of such inequalities. The authors used data from a national representative sample of people living with HIV in France (ANRS-EN12-VESPA survey). Retrospective information on social trajectory and disease characteristics from the time of HIV diagnosis was available. The risk of employment loss associated with indicators of disease severity and HIV-related workplace discrimination was computed over time since HIV diagnosis according to sociodemographic and occupational factors, using Cox proportional hazards models. Among the 478 working-age participants diagnosed as being HIV-infected in the era of multitherapies and employed at the time of HIV diagnosis, 149 experienced employment loss. After adjusting for sociodemographic and occupational factors, disease severity and self-reported HIV-related discrimination at work were significantly associated with the risk of employment loss in a socially-differentiated manner: advancement in HIV disease was associated with an increased risk of employment loss among women (HR 4.45, 95% CI 2.10 to 9.43) but not among men; self-reported experience of HIV-related discrimination at work was associated with an increased risk of employment loss among individuals with a primary/secondary educational level (HR 8.85, 95% CI 3.68 to 21.30) but not among those more educated. Chronic HIV disease affects the chances of maintaining employment in a socially-differentiated manner, resulting in increasing inequalities regarding workforce participation. Disease severity

This research was conducted to address the experience of workplace violence of Turkish workers from different sectors and to investigate the impact of the exposed violence on their psychological well-being. Data were collected anonymously with printed questionnaires from the volunteer participants and depended on self-reporting. The response rate was 79.0% (1708/2161). The prevalence of workplace violence was found to be 44.8%. The most common type was verbal violence together with mobbing (bullying). Victims of physical violence were mostly males, whereas females were found to be victims of verbal, psychological and sexual violence. Most cases did not result in legal action and the victims remained silent. Psychological well-being of exposed workers in terms of depression, anxiety and stress seemed to deteriorate. Workplace violence remains a silent epidemic in Turkey. Preventive measures against workplace violence and social support for violated workers do not exist.

The objectives of this study were to assess the current status of HIV-related knowledge, attitudes, and behavior (KAB) of employees in the private transport sector in Namibia and to compare companies with established HIV workplace program (WPPs) with those that have recently initiated the implementation of such programs. The study was designed as a cross-sectional questionnaire-based survey. Between January and March 2011, the survey was conducted in the Namibian truck transport sector in six companies of different sizes. The participants were selected randomly from the workforce. Data collection was based on a KAB questionnaire. The range of correct answers to the survey concerning the knowledge of HIV transmission was 67-95%. Twenty percent of the employees had never been tested for HIV. Additionally, risky sexual behaviors were quite prevalent and included having multiple concurrent partners and the use of sex for incentives. This study revealed that drivers and laborers were especially at risk for such behaviors. The employees of companies with established WPPs were tested for HIV more often than those of companies with new WPPs; however, aside from this difference, only minor differences were observed between the two groups. The findings of this study highlight the need for on-going HIV information and prevention campaigns that focus on the special needs of mobile and low-income workers. WPPs should be tailored accordingly and shift their focus to more practical approaches, such as voluntary counseling and testing (VCT), to increase their effectiveness.

Protecting Privacy Using k-Anonymity

El Emam, Khaled; Dankar, Fida Kamal

2008-01-01

Objective There is increasing pressure to share health information and even make it publicly available. However, such disclosures of personal health information raise serious privacy concerns. To alleviate such concerns, it is possible to anonymize the data before disclosure. One popular anonymization approach is k-anonymity. There have been no evaluations of the actual re-identification probability of k-anonymized data sets. Design Through a simulation, we evaluated the re-identification risk of k-anonymization and three different improvements on three large data sets. Measurement Re-identification probability is measured under two different re-identification scenarios. Information loss is measured by the commonly used discernability metric. Results For one of the re-identification scenarios, k-Anonymity consistently over-anonymizes data sets, with this over-anonymization being most pronounced with small sampling fractions. Over-anonymization results in excessive distortions to the data (i.e., high information loss), making the data less useful for subsequent analysis. We found that a hypothesis testing approach provided the best control over re-identification risk and reduces the extent of information loss compared to baseline k-anonymity. Conclusion Guidelines are provided on when to use the hypothesis testing approach instead of baseline k-anonymity. PMID:18579830

Understanding HIV-related stigma among Indonesian nurses

2014-01-01

Evidence indicates widespread stigmatization of persons living with HIV (PLWH) in Indonesia. Such attitudes among health care workers could impede the country’s policies for effective diagnosis and medical treatment of PLWH. Nonetheless, research to guide interventions to reduce stigma in health care settings is lacking. Also, the contributions of workplace, religion, and HIV knowledge to nurses’ HIV-related stigma are poorly understood. Our cross-sectional study aimed to describe factors associated with nurses’ stigmatizing attitudes toward PLWH. Four hundred nurses recruited from 4 hospitals in Jakarta, Indonesia, were surveyed using the Nurse AIDS Attitude Scale (NAAS) to measure stigma. Stigmatizing attitudes were significantly predicted by education, HIV training, perceived workplace stigma, religiosity, Islamic religious identification, and affiliation with the Islamic hospital. HIV knowledge was not a significant predictor of stigmatizing attitudes. Organization changes fostering workplace diversity are likely to substantially reduce stigmatizing attitudes in nurses.

African American men have the highest rates of HIV in the USA, and research has shown that stigma, mistrust of health care, and other psychosocial factors interfere with optimal engagement in care with this population. In order to further understand reducing stigma and other psychosocial issues among African American men, we conducted qualitative interviews and focus groups with African American men in two metropolitan areas in the USA: Chicago and Seattle. We examined transcripts for relationships across variables of stigma, anonymity, self-identity, and space within the context of HIV. Our analysis pointed to similarities between experiences of stigma across the two cities and illustrated the relationships between space, isolation, and preferred anonymity related to living with HIV. The men in our study often preferred that their HIV-linked identities remain invisible and anonymous, associated with perceived and created isolation from physical community spaces. This article suggests that our health care and housing institutions may influence preferences for anonymity. We make recommendations in key areas to create safer spaces for African American men living with HIV and reduce feelings of stigma and isolation.

Anonymity and Historical-Anonymity in Location-Based Services

NASA Astrophysics Data System (ADS)

Bettini, Claudio; Mascetti, Sergio; Wang, X. Sean; Freni, Dario; Jajodia, Sushil

The problem of protecting user’s privacy in Location-Based Services (LBS) has been extensively studied recently and several defense techniques have been proposed. In this contribution, we first present a categorization of privacy attacks and related defenses. Then, we consider the class of defense techniques that aim at providing privacy through anonymity and in particular algorithms achieving “historical k- anonymity” in the case of the adversary obtaining a trace of requests recognized as being issued by the same (anonymous) user. Finally, we investigate the issues involved in the experimental evaluation of anonymity based defense techniques; we show that user movement simulations based on mostly random movements can lead to overestimate the privacy protection in some cases and to overprotective techniques in other cases. The above results are obtained by comparison to a more realistic simulation with an agent-based simulator, considering a specific deployment scenario.

Factors associated with workplace violence in paramedics.

PubMed

Koritsas, Stella; Boyle, Malcolm; Coles, Jan

2009-01-01

The majority of research that has explored workplace violence has focused on establishing the prevalence of violence in different settings. In general, there is a paucity of research that explores factors that may predict or increase the risk of experiencing violence in the workplace. The aim of this research was to determine predictors of violence for paramedics. A questionnaire was developed that focused on paramedics' experiences with six forms of violence: verbal abuse, property damage/theft, intimidation, physical abuse, sexual harassment, and sexual assault. The questionnaire was distributed randomly to paramedics throughout rural Victoria and metropolitan South Australia, and completed and returned anonymously. Predictors emerged for verbal abuse, intimidation, sexual harassment, and sexual abuse. Specifically, gender was the only predictor of intimidation, sexual harassment, and sexual assault. Paramedic qualifications, how they responded to a call-out, and hours per week in direct patient contact emerged as a predictor of verbal abuse. Certain factors predict or predispose paramedics to workplace violence. The need for workplace violence education and training is imperative for the prevention of violence, as well as for its management.

Anonymous quantum nonlocality.

2014-09-26

We investigate the phenomenon of anonymous quantum nonlocality, which refers to the existence of multipartite quantum correlations that are not local in the sense of being Bell-inequality-violating but where the nonlocality is--due to its biseparability with respect to all bipartitions--seemingly nowhere to be found. Such correlations can be produced by the nonlocal collaboration involving definite subset(s) of parties but to an outsider, the identity of these nonlocally correlated parties is completely anonymous. For all n≥3, we present an example of an n-partite quantum correlation exhibiting anonymous nonlocality derived from the n-partite Greenberger-Horne-Zeilinger state. An explicit biseparable decomposition of these correlations is provided for any partitioning of the n parties into two groups. Two applications of these anonymous Greenberger-Horne-Zeilinger correlations in the device-independent setting are discussed: multipartite secret sharing between any two groups of parties and bipartite quantum key distribution that is robust against nearly arbitrary leakage of information.

In 2002, the sero-prevalence of human immunodeficiency virus-1 (HIV) in the Emergency Department (ED), University Hospital, Newark, New Jersey was 10.4%. Both HIV and hepatitis C virus (HCV) are transmitted by injection drug use (IDU) or sexual contact. However, the degree of concurrent positive HCV antibody status in HIV-infected ED patients is unknown. In this study we determined the sero-prevalence of HIV and HIVHCV in HIV-positive patients in the ED. A cross-sectional study using an anonymous sero-prevalence survey was conducted from 7/1/2008 to 8/23/2008. Medical records were reviewed and de-identified; remnant blood specimens were also de-identified and tested for HIV antibody, and if positive, HCV antibody. Of 3488 specimens, 225 (6.5%, 95% CI: 5.7-7.3%) were positive for HIV antibody. Seventy-four patients 74/225 (32.9%, 95% CI: 33.8-46.5%) were unaware of their sero-positivity. Forty percent of HIV positive patients (90/225, 95% CI: 33.8-46.5%) were HCV antibody positive. The highest seroprevalence of HIVHCV antibody was among older patients (≥ 45 years), and patients with positive urine toxicology and elevated liver function tests. Given the high prevalence of HIV and HIVHCV antibody in the ED, routine testing is important for patients ≥ 45 years with positive urine toxicology and elevated liver function tests.

To assess attitudes to HIV risk and acceptability of rapid HIV testing among clients of street-based female sex workers (FSW) in Lausanne, Switzerland, where HIV prevalence in the general population is 0.4%. The authors conducted a cross-sectional study in the red light district of Lausanne for five nights in September of 2008, 2009 and 2010. Clients of FSW were invited to complete a questionnaire in the street assessing demographic characteristics, attitudes to HIV risk and HIV testing history. All clients interviewed were then offered anonymous finger stick rapid HIV testing in a van parked on-site. The authors interviewed 112, 127 and 79 clients in 2008, 2009 and 2010, respectively. All were men, average age 32-37 years old; 40-60% were in a stable relationship. History of unprotected sex was higher with non-commercial partners (33-50%) than with FSW (6-11%); 29-46% of clients had never undergone an HIV test. Anonymous rapid HIV testing was accepted by 45-50% of clients. Out of 109 HIV tests conducted during the three study periods, none was reactive. On-site HIV counselling and testing is acceptable among clients of FSW in this urban setting. These individuals represent an unquantified population, a proportion of which has an incomplete understanding of HIV risk in the face of high-risk behaviour, with implications for potential onward transmission to non-commercial sexual partners.

Surgical staff might be considered at most risk of accidental viral infection due to their higher exposure to blood. To evaluate surgical staff concerns about occupational HIV infection, to determine contributing factors, to assess their sero-status regarding this pathogen, and the frequency of the Δ32 allele of the CCR5 gene. With the use of a self-administered anonymous questionnaire a cross-sectional sero-survey was conducted from February 2009-January 2010 among doctors/nurses from the surgical/ gynaecological wards of 16 randomly selected hospitals in Western Pomerania, Poland. Fear level was measured by the use of the VAS scale (range 0-10). Serum samples were tested by ELISA. Genotyping was performed using a PCR-AFLP assay. Response rate 84.9%; 427 participants, 88.3% females; 84.8% nurses, 15.2% doctors (median age 42 years, range 22-61 years). More than two thirds of respondents (67.2%) overestimated HIV single exposure risk. The median level of occupational HIV fear was 6.67. The prevalence of anti-HIV was 0.0% (95%CI: 0-0.9%); 1.2% (95%CI: 0.5%-2.9%) of participants were homozygotes Δ32/Δ32. The stepwise regression model revealed that job category (nurse) was associated with HIV fear (p<0.001). The risk of contracting occupational HIV infection remains low; no anti-HIV positive individuals were found among surgical staff, one in one hundred were resistant to HIV infection. Staff members, especially nurses, were much concerned with acquiring an occupational HIV infection, possibly due to the lack of knowledge on single exposure risk. Educational actions and better access to specialists which would help surgical staff in managing anxiety at the workplace is urgently needed.

Spectral Anonymization of Data

PubMed Central

Lasko, Thomas A.; Vinterbo, Staal A.

2011-01-01

The goal of data anonymization is to allow the release of scientifically useful data in a form that protects the privacy of its subjects. This requires more than simply removing personal identifiers from the data, because an attacker can still use auxiliary information to infer sensitive individual information. Additional perturbation is necessary to prevent these inferences, and the challenge is to perturb the data in a way that preserves its analytic utility. No existing anonymization algorithm provides both perfect privacy protection and perfect analytic utility. We make the new observation that anonymization algorithms are not required to operate in the original vector-space basis of the data, and many algorithms can be improved by operating in a judiciously chosen alternate basis. A spectral basis derived from the data’s eigenvectors is one that can provide substantial improvement. We introduce the term spectral anonymization to refer to an algorithm that uses a spectral basis for anonymization, and we give two illustrative examples. We also propose new measures of privacy protection that are more general and more informative than existing measures, and a principled reference standard with which to define adequate privacy protection.

Targeting HIV services to male migrant workers in southern Africa would not reverse generalized HIV epidemics in their home communities: a mathematical modeling analysis

PubMed Central

Klein, Daniel J.; Eckhoff, Philip A.; Bershteyn, Anna

2015-01-01

Background Migrant populations such as mine workers contributed to the spread of HIV in sub-Saharan Africa. We used a mathematical model to estimate the community-wide impact of targeting treatment and prevention to male migrants. Methods We augmented an individual-based network model, EMOD-HIV v0.8, to include an age-dependent propensity for males to migrate. Migrants were exposed to HIV outside their home community, but continued to participate in HIV transmission in the community during periodic visits. Results Migrant-targeted interventions would have been transformative in the 1980s to 1990s, but post-2015 impacts were more modest. When targetable migrants comprised 2% of adult males, workplace HIV prevention averted 3.5% of community-wide infections over 20 years. Targeted treatment averted 8.5% of all-cause deaths among migrants. When migrants comprised 10% of males, workplace prevention averted 16.2% of infections in the community, one-quarter of which were among migrants. Workplace prevention and treatment acted synergistically, averting 17.1% of community infections and 11.6% of deaths among migrants. These estimates do not include prevention of secondary spread of HIV or tuberculosis at the workplace. Conclusions Though cost-effective, targeting migrants cannot collapse generalized epidemics in their home communities. Such a strategy would only have been possible prior to the early 1990s. However, migrant-targeted interventions synergize with general-population expansion of HIV services. PMID:25733560

Social media, including mobile technologies and social networking sites, are being used increasingly as part of human immunodeficiency virus (HIV) prevention and treatment efforts. As an important avenue for communication about HIV, social media use may continue to increase and become more widespread. The objective of this paper is to present a comprehensive systematic review of the current published literature on the design, users, benefits, and limitations of using social media to communicate about HIV prevention and treatment. This review paper used a systematic approach to survey all literature published before February 2014 using 7 electronic databases and a manual search. The inclusion criteria were (1) primary focus on communication/interaction about HIV/acquired immunodeficiency syndrome (AIDS), (2) discusses the use of social media to facilitate communication, (3) communication on the social media platform is between individuals or a group of individuals rather than the use of preset, automated responses from a platform, (4) published before February 19, 2014, and (5) all study designs. The search identified 35 original research studies. Thirty studies had low or unclear risk of at least one of the bias items in the methodological quality assessment. Among the 8 social media platform types described, short message service text messaging was most commonly used. Platforms served multiple purposes including disseminating health information, conducting health promotion, sharing experiences, providing social support, and promoting medication adherence. Social media users were diverse in geographic location and race/ethnicity; studies commonly reported users aged 18-40 years and users with lower income. Although most studies did not specify whether use was anonymous, studies reported the importance of anonymity in social media use to communicate about HIV largely due to the stigma associated with HIV.

Gamblers Anonymous is the most widely available form of support for disordered gambling. Although chapters exist worldwide, knowledge of how attendees interact with the program is limited. The present study aimed to investigate involvement in Gamblers Anonymous among attendees, motives for attendance, and overall satisfaction with the program. Furthermore, potential gambling-related predictors of attendance versus deciding not to attend Gamblers Anonymous were investigated. A treatment-seeking sample of disordered gamblers (N = 512) from São Paulo, Brazil completed a series of self-report measures including an author-compiled Gamblers Anonymous survey. From the sample, 141 gamblers reported attending Gamblers Anonymous over the previous 30 days. An examination of involvement, satisfaction, and motives for attending Gamblers Anonymous was conducted, followed by regression analyses to assess predictors of attendance and satisfaction with the program. The majority of attendees (80%) reported some satisfaction with the program. The most common motive for attending Gamblers Anonymous was related to relapse prevention. Regression analyses revealed that greater gambling severity and number of days gambled were associated with not attending Gamblers Anonymous while giving testimonials was strongly related (OR = 6.18) to satisfaction with the program. The findings of this study contribute to the literature on Gamblers Anonymous. In particular, that members derive great satisfaction from the program and see it as a way to strengthen their abstinence goals. However, despite high satisfaction, the results also suggest that most members were passively involved in the program. More research that assesses the effectiveness of Gamblers Anonymous as either a stand-alone or adjunct treatment is needed.

Against anonymity.

PubMed

Baker, Robert

2014-05-01

In 'New Threats to Academic Freedom' Francesca Minerva argues that anonymity for the authors of controversial articles is a prerequisite for academic freedom in the Internet age. This argument draws its intellectual and emotional power from the author's account of the reaction to the on-line publication of ' After-birth abortion: why should the baby live?'--an article that provoked cascades of hostile postings and e-mails. Reflecting on these events, Minerva proposes that publishers should offer the authors of controversial articles the option of publishing their articles anonymously. This response reviews the history of anonymous publication and concludes that its reintroduction in the Internet era would recreate problems similar to those that led print journals to abandon the practice: corruption of scholarly discourse by invective and hate speech, masked conflicts of interest, and a diminution of editorial accountability. It also contends that Minerva misreads the intent of the hostile e-mails provoked by 'After-birth abortion,' and that ethicists who publish controversial articles should take responsibility by dialoguing with their critics--even those whose critiques are emotionally charged and hostile. © 2014 John Wiley & Sons Ltd.

Concept analysis: lack of anonymity.

To re-examine and expand understanding of the concept 'lack of anonymity' as a component of rural nursing theory. Early healthcare literature reports lack of anonymity as part of social and working environments, particularly rural nursing. Rural nursing theory included the first published concept analysis on lack of anonymity but lacked empirical referents. Workforce, societal and rural healthcare changes support an updated analysis. To further understand lack of anonymity, its present day use and applicability to diverse environments, research from multiple disciplines was reviewed. Concept analysis. A literature search using eight terms in eleven databases was conducted of literature published between 2008-2013. Walker and Avant's concept analysis methodology guided the analysis. The previous concept analysis is supported in part by current literature. The defining attributes, 'identifiable', 'establishing boundaries for public and private self and interconnectedness' in a community were updated. Updated antecedents include: (i) environmental context; (ii) opportunities to become visible; (iii) developing relationships and (iv) unconscious or limited awareness of public or personal privacy. Consequences are: (i) familiarity; (ii) visibility; (iii) awareness of privacy and (iv) manage or balance of lack of anonymity. Cases were constructed and empirical referents identified. The concept of lack of anonymity was updated; portions of the original definition remain unchanged. Empirical referents reveal the defining attributes in daily life and may guide future research on the effect of lack of anonymity on nursing practice. This analysis advances the conceptual understanding of rural nursing theory. © 2016 John Wiley & Sons Ltd.

Anonymity between living donors and recipients is a topic of discussion among transplant professionals. This longitudinal study explored living kidney donors' and patients' perspectives on anonymity. Prior to surgery (T0) and 3 months afterward (T1), participants in unspecified or specified indirect donation programs completed a questionnaire on their experiences with and attitudes toward anonymity as well as demographic and medical characteristics. Nonparametric tests were used to assess group differences and associations. Participants were content with anonymity at T0 and T1. Fourteen and 23% wanted to meet at T0 and T1, respectively. If the other party expressed the wish to meet, 50% (T0) and 55% (T1) would be willing to meet. Most participants agreed that meeting should be allowed if both parties agree. Attitude toward anonymity did not differ between donors/recipients, nor between T0/T1 and unspecified/specified indirect donation programs. This study showed that most donors and recipients who participated in anonymous donation schemes are in favor of a conditional approach to anonymity. Guidelines on how to revoke anonymity if both parties agree are needed and should include education about pros and cons of (non-) anonymity and a logistical plan on how, when, where, and by whom anonymity should be revoked. © 2017 Steunstichting ESOT.

Utility-preserving anonymization for health data publishing.

Publishing raw electronic health records (EHRs) may be considered as a breach of the privacy of individuals because they usually contain sensitive information. A common practice for the privacy-preserving data publishing is to anonymize the data before publishing, and thus satisfy privacy models such as k-anonymity. Among various anonymization techniques, generalization is the most commonly used in medical/health data processing. Generalization inevitably causes information loss, and thus, various methods have been proposed to reduce information loss. However, existing generalization-based data anonymization methods cannot avoid excessive information loss and preserve data utility. We propose a utility-preserving anonymization for privacy preserving data publishing (PPDP). To preserve data utility, the proposed method comprises three parts: (1) utility-preserving model, (2) counterfeit record insertion, (3) catalog of the counterfeit records. We also propose an anonymization algorithm using the proposed method. Our anonymization algorithm applies full-domain generalization algorithm. We evaluate our method in comparison with existence method on two aspects, information loss measured through various quality metrics and error rate of analysis result. With all different types of quality metrics, our proposed method show the lower information loss than the existing method. In the real-world EHRs analysis, analysis results show small portion of error between the anonymized data through the proposed method and original data. We propose a new utility-preserving anonymization method and an anonymization algorithm using the proposed method. Through experiments on various datasets, we show that the utility of EHRs anonymized by the proposed method is significantly better than those anonymized by previous approaches.

Anonymity is a security property of paramount importance, as we move steadily towards a wired, online community. Its import touches upon subjects as different as eGovernance, eBusiness and eLeisure, as well as personal freedom of speech in authoritarian societies. Trust metrics are used in anonymity networks to support and enhance reliability in the absence of verifiable identities, and a variety of security attacks currently focus on degrading a user's trustworthiness in the eyes of the other users. In this paper, we analyse the privacy guarantees of the Crowds anonymity protocol, with and without onion forwarding, for standard and adaptive attacks against the trust level of honest users.

Workplace violence is a serious and surprisingly understudied occupational hazard in social service settings. The authors of this study conducted an anonymous, Internet-based survey of Massachusetts social service agencies to estimate the incidence of physical assault and verbal threat of violence in social service agencies, understand how social service agencies collect data on workplace violence, and identify disparities in who is at risk in terms of staff education and training level and the work setting. The study gathered general descriptions of each agency and compiled incidence data on workplace violence that were collected by agencies in fiscal year 2009. The key findings of this descriptive study showed high rates of workplace violence against social services providers and a pattern of risk disparity, with significantly more risk for direct care versus clinical staff. These results are based on data routinely collected by social service agencies that typically remain unexamined. A research agenda that is sensitive to potential occupational health disparities and focuses on maximizing workplace safety in social services is needed.

To assess the prevalence of bullying in companies and health care center and identify the association between psychosocial environment and workplace bullying. A total of 847 employees at in business building companies and 146 employees at one community health service center were invited to this survey by cluster sampling during October to December 2014, using anonymous questionnaires including the general demographic information, job characteristics, job stress core scale, the social capital scale, and NAQ-R. The rate of targets of bullying in the two kinds of workplaces were 13.1% and 5.6% respectively. Workplace bullying was associated with employee's education level(χ(2)=11.17, P=0.019)and the area his or her families live in(χ(2)=5.66, P=0.017). In addition, workplace bullying was significantly associated with psychosocial work environment. Job demand was positively correlated with workplace bullying (OR=2.24, 95% CI=1.34~3.74), and workplace social support was negatively associated with workplace bullying (OR= 0.33, 95% CI=0.18~0.60). Workplace bullying can be reduced by adjusting certain working conditions that negatively affect employees who are susceptible to being bullied, giving their individual and job characteristic. Moreover, workplace bullying could also be reduced if job demands are limited and job control and social capital are increased.

For business and research oriented works engaging Data Analysis and Cloud services needing qualitative data, many organizations release huge microdata. It excludes an individual’s explicit identity marks like name, address and comprises of specific information like DOB, Pin-code, sex, marital status, which can be combined with other public data to recognize a person. This implication attack can be manipulated to acquire any sensitive information from social network platform, thereby putting the privacy of a person in grave danger. To prevent such attacks by modifying microdata, K-anonymization is used. With potentially increasing data, the effective method to anonymize it stands challenging. After series of trails and systematic comparison, in this paper, we propose three best algorithms along with its efficiency and effectiveness. Studies help researchers to identify the relationship between the values of k, degree of anonymization, choosing a quasi-identifier and focus on execution time.

Anonymization is an essential tool to protect privacy of participants in epidemiological studies. This paper classifies types of anonymization in genetic polymorphism studies, providing precise definitions. They are: 1) unlinkable anonymization at enrollment without a participant list; 2) unlinkable anonymization before genotyping with a participant list; 3) linkable anonymization; 4) unlinkable anonymization for outsiders; and 5) linkable anonymization for outsiders. The classification in view of accessibility to a table including genotype data with directly identifiable data such as names is important; if such tables exist, staff may obtain genotype information about participants. The first three modes are defined here as anonymization unaccessible to genotype data with directly identifiable information for research staff. Anonymization with a key code held by participants is possible with any of the above anonymization modes, by which participants can access to their own genotypes through telephone or internet. A guideline issued on March 29, 2001 with collaboration of three Ministries in Japan defines "anonymization in a linkable fashion" and "anonymization in an unlinkable fashion", "for the purpose of preventing the personal information from being divulged externally in violation of law, the present guidelines or a research protocol", but the contents are not clear in practice. The proposed definitions will be useful when we describe and discuss the preferable mode of anonymization for a given polymorphism study.

Diversity management: the treatment of HIV-positive employees.

Socio-demographic dimensions such as age, gender, sexual orientation, race and ethnicity are commonly included in diversity studies. With a view to helping Asian hospitality managers to manage HIV-positive employees in their workplaces through diversity management (DM) theory, this research extends the boundaries of previous diversity studies by considering Human Immunodeficiency Virus (HIV) infection as a diverse characteristic. Both quantitative and qualitative primary data were collected from purposively selected Asian hospitality managers through postal questionnaire and follow-up telephone interviews. Transformed raw data were analysed using summary statistics and template analysis. Asian hospitality managers agreed that DM would be appropriate in the management of HIV-positive employees and that it could generate substantial benefits for employees and employers. However, they believe that the successful adoption and implementation of DM is not easy; it requires training and, ideally, the recruitment of experienced directors. Nevertheless, Asian hospitality managers are confident that implementing DM to manage HIV-positive employees can enhance tolerance, improve understanding and promote equality. The purposive sampling technique and the small number of respondents have impacted the external validity of the study. However, this exploratory study initiates an equality discussion to include HIV-positive employees in DM discourse beyond antidiscrimination legislation. It also supplements the sparse literature addressing HIV-positive employees in the Asian hospitality workplace. Asian hospitality managers are advised to understand and employ DM to treat HIV-positive employees fairly to overcome hospitality workplace marginalisation, discrimination and stigmatisation.

Anonymous Transactions in Computer Networks

Dolev, Shlomi; Kopeetsky, Marina

We present schemes for providing anonymous transactions while privacy and anonymity are preserved, providing user anonymous authentication in distributed networks such as the Internet. We first present a practical scheme for anonymous transactions while the transaction resolution is assisted by a Trusted Authority. This practical scheme is extended to a theoretical scheme where a Trusted Authority is not involved in the transaction resolution. Given an authority that generates for each player hard to produce evidence EVID (e. g., problem instance with or without a solution) to each player, the identity of a user U is defined by the ability to prove possession of said evidence. We use Zero-Knowledge proof techniques to repeatedly identify U by providing a proof that U has evidence EVID, without revealing EVID, therefore avoiding identity theft.

Campaigns have been conducted in a number of low HIV prevalence African settings, as a strategy to expand HIV testing, and it is important to assess the extent to which individual rights and quality of care are protected during campaigns. In this article we investigate provider and client perceptions of ethical issues, including whether they think that accessibility of counseling and testing sites during campaigns may hinder confidentiality. To examine how campaigns have functioned in Burkina Faso, we undertook a qualitative study based on individual interviews and focus group discussions with 52 people (providers and clients tested during or outside campaigns and individuals never tested). Thematic analysis was performed on discourse about perceptions and experiences of HIV-testing campaigns, quality of care and individual rights. Respondents value testing accessibility and attractiveness during campaigns; clients emphasize convenience, ripple effect, the sense of not being alone, and the anonymity resulting from high attendance. Confronted with numerous clients, providers develop context-specific strategies to ensure consent, counseling, confidentiality and retention in the testing process, and they adapt to workplace arrangements, local resources and social norms. Clients appreciate the quality of care during campaigns. However, new ethical issues arise about confidentiality and accessibility. Confidentiality of HIV-status may be jeopardized due to local social norms that encourage people to share their results with others, when HIV-positive people may not wish to do so. Providers' ethical concerns are consistent with WHO norms known as the '5 Cs,' though articulated differently. Clients and providers value the accessibility of testing for all during campaigns, and consider it an ethical matter. The study yields insights on the way global norms are adapted or negotiated locally. Future global recommendations for HIV testing and counseling campaigns should

Anon-Pass: Practical Anonymous Subscriptions.

We present the design, security proof, and implementation of an anonymous subscription service. Users register for the service by providing some form of identity, which might or might not be linked to a real-world identity such as a credit card, a web login, or a public key. A user logs on to the system by presenting a credential derived from information received at registration. Each credential allows only a single login in any authentication window, or epoch . Logins are anonymous in the sense that the service cannot distinguish which user is logging in any better than random guessing. This implies unlinkability of a user across different logins. We find that a central tension in an anonymous subscription service is the service provider's desire for a long epoch (to reduce server-side computation) versus users' desire for a short epoch (so they can repeatedly "re-anonymize" their sessions). We balance this tension by having short epochs, but adding an efficient operation for clients who do not need unlinkability to cheaply re-authenticate themselves for the next time period. We measure performance of a research prototype of our protocol that allows an independent service to offer anonymous access to existing services. We implement a music service, an Android-based subway-pass application, and a web proxy, and show that adding anonymity adds minimal client latency and only requires 33 KB of server memory per active user.

In many countries, HIV, hepatitis B virus (HBV), and hepatitis C virus (HCV) infected individuals may face discrimination and mistreatment from coworkers. Effective interventions to reduce workplace discrimination are therefore needed to protect these vulnerable populations. The current study investigated potential associations between sociodemographic factors and prejudice toward HIV and HBV/HCV infected colleagues within a Japanese working population. An online anonymous, nationwide internet survey was administered to a cross-section of approximately 3,000 individuals in Japan. The survey comprised 14 questions focusing on demographics (five items), basic HIV or HBV/HCV knowledge (eight items), and potential prejudice toward HIV or HBV/HCV infected colleagues (one item). The sociodemographic characteristics evaluated were sex, age, educational level, employment status, and individual income; with multiple logistic regression used for the analysis. In total, 3,055 individuals were recruited for the HIV related survey and 3,129 for the HBV/HCV related survey. Older age was significantly and positively associated with prejudice toward HIV infected colleagues (p<0.01) and negatively associated with prejudice toward HBV/HCV infected colleagues (p<0.01). Statistically significant associations were not observed between other sociodemographic characteristics and potential prejudice toward HIV and HBV/HCV infected coworkers. Overall, this study suggests that age may be associated with prejudice toward HIV and HBV/HCV infected colleagues among the working age population of Japan. As such, policy makers should consider the age of participants when formulating efforts to reduce prejudice toward HIV and HBV/HCV infected workers.

To evaluate the impact of HIV on businesses in Zambia and to assess attitudes towards HIV and HIV education in the workplace. The personnel managers of 33 companies with a total workforce of 10,204 in Lusaka and in towns in the Copperbelt were visited by two members of the study team. The study was discussed and a questionnaire about the impact of HIV on their company was explained and left for completion from company records. All 33 questionnaires were returned. HIV was recognised to be a problem by 30 companies questioned. Seven said that it had affected recruitment and 11 production. 23 companies carried out pre-employment medicals. 17 companies demanded that some or all of their employees had an HIV test before employment. Nine companies were sure that a positive HIV test would prevent employment, 15 were unsure saying that there was no particular company policy. Two companies had recently changed their policy and had stopped discriminating against those with HIV. 12 companies had some HIV educational material available for their employees and five had someone (or an organisation that they used) to whom they could refer employees for HIV information and advice. Condoms were provided free to staff by five of the companies. All thought that HIV education in the workplace was an appropriate intervention. Mortality data showed a sevenfold increase in the crude mortality from 0.25-1.8 per 100 person-years from 1987-93, and an increasing trend in reported deaths from AIDS and HIV related conditions. HIV is having an important impact in the workplace in urban Zambia. Although many companies insist on pre-employment medicals, often including HIV testing, few have developed policies relating to test results. Some companies have instituted HIV education but there is a demand for this service to be available more widely. There has been a striking increase in mortalities in this working population, which seems likely to be related to HIV, although the cause of most deaths

In 2001 the Austrian government provided the legal means that formally enabled "anonymous birth": a woman can now give birth in any hospital in Austria without giving her name or insurance number, the baby is taken into care by social services and placed with adoptive parents. The cost of the hospital stay is covered from public funds. These measures were put into effect after some highly publicized cases of infant abandonment and neonaticide in Austria. In the mostly rural and small-town province of Tyrol province in western Austria (687,000 inhabitants, 7000 births per year) four cases of neonaticide were discovered in the years from 1996 to 2004. One child was abandoned inside a hospital. Since 2001 two women have made use of the "anonymous birth" option. Neither had had any pregnancy controls, both showed up at or near term with contractions. They delivered healthy infants that were then taken into care by local adoption services. Both women were extensively counselled by psychologists, social workers, medical and midwifery staff and both insisted on their original decision to remain anonymous. A few weeks later one of the women found herself at the centre of a criminal investigation for infanticide after anonymous letters were sent to family members insinuating she had done away with the child. Police stopped that investigation when hospital staff confirmed that the woman had had an "anonymous" delivery. Despite the option of legal "anonymous" birth free of charge in modern hospitals there are still cases of infant abandonment and neonaticide in Austria. It is proposed that the women who opt for anonymous birth may not be the women who would otherwise kill their babies. Instead, it appears that the women opted for anonymity to escape the probably well-intentioned but overbearing attention of their families and of social services. It is doubtful that the option of anonymous birth will lead to a complete disappearance of infanticide and infant abandonment in

Until now, research on sexual behavior and HIV in Israel has been carried out mainly on the general population, and focused primarily on defining populations at risk, without adequate consideration given to the reasons bringing these populations to be tested, and their specific sexual behaviors. In Israel, one can choose whether to take an HIV test in confidential centers (giving one's name under medical confidentiality) or in anonymous centers (Israel AIDS Task Force in Tel Aviv and Beer Sheva, Levinsky Clinic in Tel Aviv and Haparsim Clinic in Haifa]. At least 21% of the clients of the anonymous testing centers in Israel belong to a high risk population in contrast to 2.6% in confidential clinics, and so, in this study, we hypothesize that characterization of sexual behavior patterns in anonymous testing centers might enable us to better characterize sexual behavior patterns in high risk populations. In this cross-sectional study, we used questionnaires distributed in the clinics by the Israel AIDS Task Force in order to characterize their clinic's clients. The questionnaires were completed by the Israel AIDS Task Force consultants during the consultation period at which the anonymous test was performed. Data collected included: gender, age, testing history, specific sexual behaviors and reasons for applying for the current test. A total of 926 questionnaires were collected; 29.9% of them were of female patients. The average age was 29.47 years (1±8.66]; 21.3% of the clients were men who have sex with men [MSM]; only 2.3% of the clients belonged to other high risk populations. In all groups, the majority of the patients reported high risk sexual behavior (any sexual contact without a condom) and the average age for the first test was much higher than the average age of first sexual intercourse common in Israel. Women reported more participation in unprotected vaginal intercourse than heterosexual men, and a substantial part of MSM reported performing unprotected

To examine the relationship of Human Immunodeficiency Virus (HIV) clinical markers and socio-demographic characteristics with long-term formal employment among people living with HIV (PLHIV). 554 adults, 55% females, on HIV treatment for at least two years at two public hospitals in Johannesburg, South Africa. A retrospective cohort design, tracing changes in study participants' formal employment status since the first HIV-positive diagnosis. Data collection included historical medical records review and interviewer-administered questionnaires. 44% of all study participants (39% and 49% among males and females, respectively) were formally employed at the time of the study, primarily in low-skilled jobs in the private sector. The majority (83%) of males and 60% of females remained in formal employment since being diagnosed as HIV-positive. Female gender, education to grade 12 or higher, a smaller household size and being married were significantly associated with current formal employment. Formal employment was unrelated to HIV treatment indicators (CD4 count, viral load and duration since diagnosis). Of those in formal employment, 68 (28%) were aware of HIV policies at their workplaces, which was also positively associated with the duration in their current employment. PLHIV in developing country contexts can enter into and maintain formal employment, especially when treatment and workplace support are available. Thus, employer organisations should implement effective workplace HIV policies to enhance employment experiences of their workforce living with HIV. Care and support services for people on HIV treatment should also address their career development needs.

Three Asian companies are investing in HIV/AIDS education and prevention schemes because they are starting to feel the effects of the HIV/AIDS pandemic on their workforces. A total of 17 companies from the region signed a document in the Fifth International Congress on AIDS in Asia and the Pacific committing to the fight against AIDS. The group said that effective workplace programs can prevent an increase in absenteeism, health care costs and labor turnover, a decrease in productivity, loss of experienced personnel and the need for increased resources to hire and retrain replacements. American International Assurance in Thailand accredits companies with effective HIV/AIDS campaigns in the workplace and gives them a 5-10% discount on premiums on group life insurance policies. At Freeport Mining in Indonesia, an HIV/AIDS campaign markedly improved condom usage rates and decreased incidence of sexually transmitted diseases (STDs) among workers. Meanwhile, India's Tata Tea Limited expanded its health services to include surveys, training, education, and counseling on HIV/AIDS and STDs.

A Novel Multi-Receiver Signcryption Scheme with Complete Anonymity.

2016-01-01

Anonymity, which is more and more important to multi-receiver schemes, has been taken into consideration by many researchers recently. To protect the receiver anonymity, in 2010, the first multi-receiver scheme based on the Lagrange interpolating polynomial was proposed. To ensure the sender's anonymity, the concept of the ring signature was proposed in 2005, but afterwards, this scheme was proven to has some weakness and at the same time, a completely anonymous multi-receiver signcryption scheme is proposed. In this completely anonymous scheme, the sender anonymity is achieved by improving the ring signature, and the receiver anonymity is achieved by also using the Lagrange interpolating polynomial. Unfortunately, the Lagrange interpolation method was proven a failure to protect the anonymity of receivers, because each authorized receiver could judge whether anyone else is authorized or not. Therefore, the completely anonymous multi-receiver signcryption mentioned above can only protect the sender anonymity. In this paper, we propose a new completely anonymous multi-receiver signcryption scheme with a new polynomial technology used to replace the Lagrange interpolating polynomial, which can mix the identity information of receivers to save it as a ciphertext element and prevent the authorized receivers from verifying others. With the receiver anonymity, the proposed scheme also owns the anonymity of the sender at the same time. Meanwhile, the decryption fairness and public verification are also provided.

HIV disclosure among adults living with HIV.

2008-01-01

Research on disclosure among heterosexual adult person(s) living with HIV (PLH) was reviewed, omitting disclosure of parental HIV to children. Disclosure has been studied within five additional relational contexts: with partners, family members, friends, healthcare professionals and in work settings. Disclosure is higher among women than men, among Latino and white compared to African-American families, and among younger compared to older HIV-positive adults. Most PLH disclose to their sexual partners and family members, yet there is a significant minority who do not disclose. Similarly, rates of disclosure to employers range from 27-68%, suggesting broad variability in perceived consequences of employment disclosures. Of concern, 40% of PLH do not consistently disclose to their healthcare professionals. Rather than examine HIV disclosures in the context of relationships, it is possible to understand disclosures around personal identity. Disclosure decisions are often made to tell everyone (making HIV status a central attribute of one's identity), no one (requiring strategies for securing social support while remaining anonymous) or some people (requiring strategic decisions based on context). Given that disclosure decisions are central to personal identity, future data on disclosure and interventions designed to increase disclosure or comfort with disclosure must focus on communication strategies adopted by PLH to present a coherent identity.

Approximately 15% of HIV-infected men who have sex with men (MSM) engaged in HIV primary care have been diagnosed as having a sexually transmitted infection (STI) in the past year, yet STI testing frequency remains low. We sought to quantify STI testing frequencies at a large, urban HIV care clinic, and to identify patient- and provider-related barriers to increased STI testing. We extracted laboratory data in aggregate from the electronic medical record to calculate STI testing frequencies (defined as the number of HIV-infected MSM engaged in care who were tested at least once over an 18-month period divided by the number of MSM engaged in care). We created anonymous surveys of patients and providers to elicit barriers. Extragenital gonorrhea and chlamydia testing was low (29%-32%), but the frequency of syphilis testing was higher (72%). Patients frequently reported high-risk behaviors, including drug use (16.4%) and recent bacterial STI (25.5%), as well as substantial rates of recent testing (>60% in prior 6 months). Most (72%) reported testing for STI in HIV primary care, but one-third went elsewhere for "easier" (42%), anonymous (21%), or more frequent (16%) testing. HIV primary care providers lacked testing and treatment knowledge (25%-32%) and cited lack of time (68%), discomfort with sexual history taking and genital examination (21%), and patient reluctance (39%) as barriers to increased STI testing. Sexually transmitted infection testing in HIV care remains unacceptably low. Enhanced education of providers, along with strategies to decrease provider time and increase patient ease and frequency of STI testing, is needed.

Sensitive biomedical data is often collected from distributed sources, involving different information systems and different organizational units. Local autonomy and legal reasons lead to the need of privacy preserving integration concepts. In this article, we focus on anonymization, which plays an important role for the re-use of clinical data and for the sharing of research data. We present a flexible solution for anonymizing distributed data in the semi-honest model. Prior to the anonymization procedure, an encrypted global view of the dataset is constructed by means of a secure multi-party computing (SMC) protocol. This global representation can then be anonymized. Our approach is not limited to specific anonymization algorithms but provides pre- and postprocessing for a broad spectrum of algorithms and many privacy criteria. We present an extensive analytical and experimental evaluation and discuss which types of methods and criteria are supported. Our prototype demonstrates the approach by implementing k-anonymity, ℓ-diversity, t-closeness and δ-presence with a globally optimal de-identification method in horizontally and vertically distributed setups. The experiments show that our method provides highly competitive performance and offers a practical and flexible solution for anonymizing distributed biomedical datasets.

Anonymous transmission is an interesting and crucial issue in computer communication area, which plays a supplementary role to data privacy. In this paper, we put forward a privacy preserving quantum anonymous transmission protocol based on entanglement relay, which constructs anonymous entanglement from EPR pairs instead of multi-particle entangled state, e.g. GHZ state. Our protocol achieves both sender anonymity and receiver anonymity against an active adversary and tolerates any number of corrupt participants. Meanwhile, our protocol obtains an improvement in efficiency compared to quantum schemes in previous literature.

Though Black and Hispanic men who have sex with men (MSM) are at an increased risk for HIV, few HIV risk reduction interventions that target HIV-positive MSM, and even fewer that use technology, have been designed to target these groups. Despite similar rates of social media and technology use across racial/ethnic groups, online engagement of minority MSM for HIV prevention efforts is low. Since minority MSM tend to have less representation in online HIV prevention studies, the goals of this online anonymous study of HIV-positive gay-identified men were to test the feasibility of conducting targeted recruitment by race/ethnicity and sexual orientation, to assess technology and social media use, and to assess global HIV transmission risk. In 2011, an anonymous online survey was conducted among 463 members of an HIV-positive personals website. Emails were sent to a subset of HIV-positive male members who self-identified as gay. While 57 % were White, substantial proportions of participants were Black (20 %) or Hispanic (18 %). Median age was 46 (range 18-79). Men who reported using 3 or more websites or apps to meet sex partners were significantly more likely to report anal intercourse (AOR 4.43, p < .001) and condomless anal sex (CAS) (AOR 2.70, p < .05) in the past 3 months. The only predictor of CAS with HIV-negative or unknown status partners was being under age 30 (AOR 3.38, p < .01). This study helped to inform online targeted recruitment techniques, access to technology and social media use, and sexual risk among a diverse sample of HIV-positive gay men. Efficacy trials of technology-based HIV prevention interventions targeting high-risk minority HIV-positive MSM are warranted.

Workplace bullying and burnout among healthcare employees: The moderating effect of control-related resources.

Workplace bullying is a widespread and challenging problem in healthcare organizations, bearing negative consequences for individuals and organizations. Drawing on the job demands-resources theory, in this study, we examined the relationship between workplace bullying and burnout among healthcare employees, as well as the moderating role of job autonomy and occupational self-efficacy in this relationship. Using a cross-sectional design with anonymous questionnaires, data were collected from two samples of 309 healthcare employees in a mental health facility, and 105 nurses studying for their bachelor degree in health systems administration. The findings indicated that workplace bullying was positively related to burnout dimensions, and that this relationship was moderated by job autonomy and occupational self-efficacy resources. Job autonomy interacted with workplace bullying in predicting emotional exhaustion and depersonalization; the interaction of bullying with occupational self-efficacy significantly predicted depersonalization. These results underscore the importance of control-related resources in mitigating the harmful effects of workplace bullying on employees. Implications for research and managerial practices are discussed. © 2017 John Wiley & Sons Australia, Ltd.

Anon-Pass: Practical Anonymous Subscriptions

PubMed Central

Lee, Michael Z.; Dunn, Alan M.; Katz, Jonathan; Waters, Brent; Witchel, Emmett

2014-01-01

We present the design, security proof, and implementation of an anonymous subscription service. Users register for the service by providing some form of identity, which might or might not be linked to a real-world identity such as a credit card, a web login, or a public key. A user logs on to the system by presenting a credential derived from information received at registration. Each credential allows only a single login in any authentication window, or epoch. Logins are anonymous in the sense that the service cannot distinguish which user is logging in any better than random guessing. This implies unlinkability of a user across different logins. We find that a central tension in an anonymous subscription service is the service provider’s desire for a long epoch (to reduce server-side computation) versus users’ desire for a short epoch (so they can repeatedly “re-anonymize” their sessions). We balance this tension by having short epochs, but adding an efficient operation for clients who do not need unlinkability to cheaply re-authenticate themselves for the next time period. We measure performance of a research prototype of our protocol that allows an independent service to offer anonymous access to existing services. We implement a music service, an Android-based subway-pass application, and a web proxy, and show that adding anonymity adds minimal client latency and only requires 33 KB of server memory per active user.

Circuit courts clash over HIV in the workplace.

PubMed

1997-09-19

Some of the major differences of opinions between the circuit courts on issues affecting HIV and employment are examined. In the seven years since the passing of the Americans with Disabilities Act (ADA), there has been disagreement among the circuits relative to the interpretation of the law. At the heart of the debate is whether or not HIV infection, without symptoms of AIDS, actually qualifies for a disability under the meaning and intent of the ADA. Another fundamental issue is whether or not reproduction is considered a major life activity under the ADA. Federal circuit courts have also considered what happens to patients in the latter stages of HIV diseases, when symptoms are so pronounced that he or she qualifies for disability benefits including Social Security or private disability plans. There is disagreement among the circuits as to whether insurance products, including those provided through an employee benefit program, are covered under the ADA. As of this date, the U.S. Supreme Court has not intervened on any of the HIV/ADA-related cases.

HIV positive Black men who have sex with men (MSM) are retained in HIV medical care at suboptimal rates. Interventions targeted to Black MSM are needed to help to improve their retention in care. The purposes of this study were to investigate the use of mobile technology among HIV+ Black MSM and to explore participants' thoughts about the use of mobile technology for HIV retention in care interventions. Twenty-two HIV+ Black MSM completed a technology use survey and participated in a qualitative interview regarding technology-based interventions. The majority of participants (95%) had access to a cell phone, and used their phones frequently (median 3 hours/day). Men preferred interventions that would allow for anonymous participation and that would provide individually tailored support. Mobile technology is a promising approach to intervention delivery for both younger and older HIV+ Black MSM. These interventions should incorporate features that are desirable to men (i.e., anonymous participation and individual tailoring).

A randomized study of the effect of anonymity, quasi-anonymity, and Certificates of Confidentiality on postpartum women's disclosure of sensitive information.

PubMed

Beatty, Jessica R; Chase, Sara K; Ondersma, Steven J

2014-01-01

Under-reporting of substance use and other sensitive information is a substantial threat to internal study validity, particularly during the perinatal period. Anonymous approaches are associated with greater disclosure but are incompatible with longitudinal follow-up. Alternative approaches include use of a U.S. Federal Certificate of Confidentiality (CoC) and quasi-anonymous methods, in which there is no link between name and data. However, the relative effect of these procedures on disclosure is unknown. This randomized study was designed to evaluate the effects of consent condition (anonymous, quasi-anonymous, CoC, and traditional confidentiality) on disclosure of sensitive information among postpartum women. Participants were 200 postpartum, primarily African-American women who were randomly assigned to one of the four consent conditions and completed a brief computer-delivered assessment of alcohol and drug use, sexual risk, intimate partner violence, and emotional distress. Participants in the anonymous and quasi-anonymous conditions disclosed significantly more sensitive information than those in the traditional consent condition. In contrast, no advantage in overall disclosure was observed for the CoC condition. This result was largely consistent across specific content areas with the exception of emotional distress, disclosure of which was unrelated to consent condition. Although use of a CoC has limited impact on disclosure, the quasi-anonymous method may increase disclosure to a similar extent as full anonymity. Quasi-anonymous approaches should be considered when under-reporting is likely, a context in which the disadvantages of this approach must be balanced against its advantages.

K-Anonymous Multi-party Secret Handshakes

NASA Astrophysics Data System (ADS)

Xu, Shouhuai; Yung, Moti

Anonymity-protection techniques are crucial for various commercial and financial transactions, where participants are worried about their privacy. On the other hand, authentication methods are also crucial for such interactions. Secret handshake is a relatively recent mechanism that facilitates privacy-preserving mutual authentication between communicating peers. In recent years, researchers have proposed a set of secret handshake schemes based on different assumptions about the credentials used: from one-time credentials to the more general PKI-like credentials. In this paper, we concentrate on k-anonymous secret handshake schemes based on PKI-like infrastructures. More specifically, we deal with the k-anonymous m-party (m > 2) secret handshake problem, which is significantly more involved than its two-party counterpart due to the following: When an honest user hand-shakes with m - 1 parties, it must be assured that these parties are distinct; otherwise, under the mask of anonymity a dishonest participant may clone itself in a single handshake session (i.e., assuming multiple personalities).

Sexual behavior is the dominant mode of HIV transmission in China, and young female migrants are among the populations at highest risk. This article examines how HIV-related risk behaviors among female migrants might vary according to workplace settings. Participants were young female migrants recruited from three workplace settings-factories, restaurants and entertainment venues. In a cross-sectional survey, we assessed 457 participants' sociodemographic characteristics, HIV/AIDS-related knowledge, condom use knowledge, sexual behaviors, condom use behavior and reproductive health factors. Participants working in entertainment venues were significantly more likely than those working in factories and restaurants to report sexual behavior, unprotected sex, multiple pregnancy terminations and sexually transmitted infections (STI). However, participants working in factories and restaurants reported significantly lower levels of HIV/AIDS knowledge, condom use knowledge, condom use self-efficacy and history of HIV/AIDS counseling and testing. Independent correlates of unprotected sex included employment in an entertainment venue, abortion history and sexual self-efficacy. Independent correlates of STI or genitourinary tract infection included employment in an entertainment venue, abortion history, recent migration and recent unprotected sex. These findings indicate a need for sexual and reproductive health interventions prioritizing young female migrants, and call for programs that can be incorporated into different workplace settings. © The Author 2015.

Ethical considerations of providers and clients on HIV testing campaigns in Burkina Faso

PubMed Central

2014-01-01

Background Campaigns have been conducted in a number of low HIV prevalence African settings, as a strategy to expand HIV testing, and it is important to assess the extent to which individual rights and quality of care are protected during campaigns. In this article we investigate provider and client perceptions of ethical issues, including whether they think that accessibility of counseling and testing sites during campaigns may hinder confidentiality. Methods To examine how campaigns have functioned in Burkina Faso, we undertook a qualitative study based on individual interviews and focus group discussions with 52 people (providers and clients tested during or outside campaigns and individuals never tested). Thematic analysis was performed on discourse about perceptions and experiences of HIV-testing campaigns, quality of care and individual rights. Results Respondents value testing accessibility and attractiveness during campaigns; clients emphasize convenience, ripple effect, the sense of not being alone, and the anonymity resulting from high attendance. Confronted with numerous clients, providers develop context-specific strategies to ensure consent, counseling, confidentiality and retention in the testing process, and they adapt to workplace arrangements, local resources and social norms. Clients appreciate the quality of care during campaigns. However, new ethical issues arise about confidentiality and accessibility. Confidentiality of HIV-status may be jeopardized due to local social norms that encourage people to share their results with others, when HIV-positive people may not wish to do so. Providers’ ethical concerns are consistent with WHO norms known as the ‘5 Cs,’ though articulated differently. Clients and providers value the accessibility of testing for all during campaigns, and consider it an ethical matter. The study yields insights on the way global norms are adapted or negotiated locally. Conclusions Future global recommendations for HIV

Predictors of workplace sexual health policy at sex work establishments in the Philippines.

Based on the literature, we identified manager and establishment characteristics that we hypothesized are related to workplace policies that support HIV protective behavior. We developed a sexual health policy index consisting of 11 items as our outcome variable. We utilized both bivariate and multivariate analysis of variance. The significant variables in our bivariate analyses (establishment type, number of employees, manager age, and membership in manager association) were entered into a multivariate regression model. The model was significant (p<.01), and predicted 42) of the variability in the development and management of a workplace sexual health policy supportive of condom use. The significant predictors were number of employees and establishment type. In addition to individually-focused CSW interventions, HIV prevention programs should target managers and establishment policies. Future HIV prevention programs may need to focus on helping smaller establishments, in particular those with less employees, to build capacity and develop sexual health policy guidelines.

Objective To determine if significant differences exist in substance use among people living with HIV/AIDS (PLWHA) before and after establishing their HIV infection status. Method The study participants are HIV positive clients of a community based HIV/AIDS outreach facility located in Montgomery, Alabama. The questionnaire includes demographics, substance use and risky sexual behaviors pertaining to HIV transmission. Each participant completed an anonymous questionnaire. A total of 341 questionnaires were distributed and 326 were fully completed and returned, representing a response rate of 96%. Results Findings revealed a statistically significant difference in alcohol consumption before sex among PLWHA before and after establishing their HIV infection status (p = .001). No significant differences were observed among participants who reported as having used drugs intravenously (p = .89), and among those sharing the same syringe/needle with another person (p = .87) before and after establishing their HIV infection status. Conclusion There is continued substance use and alcohol consumption before sex among PLWHA after establishing their HIV status despite clear evidence of such risky behaviors that could lead to an increase in exposure to HIV.

2017-04-01

This study examined the relationships of HIV/AIDS beliefs, self-efficacy for AIDS preventive behaviors, perception of HIV as a chronic disease, and HIV risk behaviors among young Thai men who have sex with men. Participants were recruited for a self-administered anonymous survey through Facebook. Logistic regression analysis was used to identify factors associated with each of four HIV risk behavior outcomes. Factors associated with sexual risk behaviors included age (18 and 21 years), having a current regular male partner, self-efficacy for AIDS preventive behaviors (self-efficacy in refusing sexual intercourse, self-efficacy in questioning potential sex partners, and self-efficacy in condom use), AIDS health belief (perceived susceptibility to HIV/AIDS, perceived severity of HIV/AIDS, perceived barriers to condom use, and cues to action for HIV/AIDS prevention), and perception of HIV/AIDS as a chronic disease (perceived HIV sero-status disclosure). Knowledge generated from this study has the potential to inform prevention messages for young Thai MSM.

A smart-card-based user authentication scheme for wireless sensor networks (hereafter referred to as a SCA-WSN scheme) is designed to ensure that only users who possess both a smart card and the corresponding password are allowed to gain access to sensor data and their transmissions. Despite many research efforts in recent years, it remains a challenging task to design an efficient SCA-WSN scheme that achieves user anonymity. The majority of published SCA-WSN schemes use only lightweight cryptographic techniques (rather than public-key cryptographic techniques) for the sake of efficiency, and have been demonstrated to suffer from the inability to provide user anonymity. Some schemes employ elliptic curve cryptography for better security but require sensors with strict resource constraints to perform computationally expensive scalar-point multiplications; despite the increased computational requirements, these schemes do not provide user anonymity. In this paper, we present a new SCA-WSN scheme that not only achieves user anonymity but also is efficient in terms of the computation loads for sensors. Our scheme employs elliptic curve cryptography but restricts its use only to anonymous user-to-gateway authentication, thereby allowing sensors to perform only lightweight cryptographic operations. Our scheme also enjoys provable security in a formal model extended from the widely accepted Bellare-Pointcheval-Rogaway (2000) model to capture the user anonymity property and various SCA-WSN specific attacks (e.g., stolen smart card attacks, node capture attacks, privileged insider attacks, and stolen verifier attacks).

Patients and their relatives exposed to mental stress caused by hospitalization or illness might use violence against healthcare staff and interfere with quality healthcare. The aim of this study was to investigate incidences of workplace violence and the attributes of healthcare staff who are at high risk. A questionnaire-based, anonymous, and self-administered cross-sectional survey. Healthcare staff (n = 11,095) of 19 hospitals in Japan. Incidence rates and adjusted odd ratios of workplace violence were calculated to examine the effect of attributes of healthcare staff to workplace violence by using logistic regression analysis. The response rate for survey completion was 79.1% (8711/11,095). Among the respondents, 36.4% experienced workplace violence by patients or their relatives in the past year; 15.9% experienced physical aggression, 29.8% experienced verbal abuse, and 9.9% experienced sexual harassment. Adjusted odds ratios of physical aggression were significantly high in psychiatric wards, critical care centers/intensive care units (ICU)/cardiac care units (CCU), long-term care wards, for nurses, nursing aides/care workers, and for longer working hours. Adjusted odds ratios of verbal abuse were significantly high in psychiatric wards, long-term care wards, outpatient departments, dialysis departments, and for longer years of work experience, and for longer working hours. Adjusted odds ratios of sexual harassment were significantly high in dialysis departments, for nurses, nursing aides/care workers, technicians, therapists and females. The general ward and direct interaction with patients were common risk factors for each type of workplace violence. The mechanisms and the countermeasures for each type of workplace violence at those high-risk areas should be investigated. Copyright © 2011 Society of Hospital Medicine.

Sussman, Steve

2010-03-01

The investigation of the applicability of Alcoholics Anonymous/Narcotics Anonymous (AA/NA) for teens has only been a subject of empirical research investigation since the early 1990s. In the present review, the author describes teen involvement in AA/NA programming, provides an exhaustive review of the outcomes of 19 studies that used an AA/NA model as part of their formal teen substance abuse treatment programs, and provides data on the effects of AA/NA attendance on abstinence at follow-up, on which youth tend to become involved in AA/NA, and on mediation of the benefits of AA/NA participation. In addition, the author suggests the reasons for somewhat limited participation by teens in more informal, community-based 12-step meetings, and makes suggestions for maximizing participation at meetings in the community. The author concludes that AA/ NA participation is a valuable modality of substance abuse treatment for teens and that much can be done to increase teen participation, though more research is needed.

Little is known about HIV prevalence and risk among men who have sex with men (MSM) in much of the Middle East, including Lebanon. Recent national-level surveillance has suggested an increase in HIV prevalence concentrated among men in Lebanon. We undertook a biobehavioral study to provide direct evidence for the spread of HIV. MSM were recruited by respondent-driven sampling, interviewed, and offered HIV testing anonymously at sites located in Beirut, Lebanon, from October 2014 through February 2015. The interview questionnaire was designed to obtain information on participants' sociodemographic situation, sexual behaviors, alcohol and drug use, health, HIV testing and care, and experiences of stigma and discrimination. Individuals not reporting an HIV diagnosis were offered optional, anonymous HIV testing. Among the 292 MSM recruited, we identified 36 cases of HIV (12.3%). A quarter of the MSM were born in Syria and recently arrived in Lebanon. Condom use was uncommon; 65% reported condomless sex with other men. Group sex encounters were reported by 22% of participants. Among the 32 individuals already aware of their infection, 30 were in treatment and receiving antiretroviral therapy. HIV prevalence was substantially increased over past estimates. Efforts to control future increases will have to focus on reducing specific risk behaviors and experience of stigma and abuse, especially among Syrian refugees.

Relationship between HIV stigma and self-isolation among people living with HIV in Tennessee.

HIV stigma is a contributing factor to poor patient outcomes. Although HIV stigma has been documented, its impact on patient well-being in the southern US is not well understood. Thirty-two adults participated in cognitive interviews after completing the Berger HIV or the Van Rie stigma scale. Participant responses were probed to ensure the scales accurately measured stigma and to assess the impact stigma had on behavior. Three main themes emerged regarding HIV stigma: (1) negative attitudes, fear of contagion, and misperceptions about transmission; (2) acts of discrimination by families, friends, health care providers, and within the workplace; and (3) participants' use of self-isolation as a coping mechanism. Overwhelming reluctance to disclose a person's HIV status made identifying enacted stigma with a quantitative scale difficult. Fear of discrimination resulted in participants isolating themselves from friends or experiences to avoid disclosure. Participant unwillingness to disclose their HIV status to friends and family could lead to an underestimation of enacted HIV stigma in quantitative scales.

Comments on “Anonymous reviewers” [“Anonymous reviews: Self-serving, counterproductive, and unacceptable”

Robinove, Charles J.

Mryl Beck's Forum article denouncing anonymous reviews (Eos, 1 July 2003) is right on the money. Perhaps he read my letter in Applied Physics in 1990 also denouncing anonymous reviews.Some years ago, I received an anonymous review of a paper I had submitted for journal publication. The reviewer raised such interesting questions that I wanted to discuss them with him. I phoned the editor of the journal and asked if he would tell me the name of the reviewer. He politely declined, but when I told him I thought I recognized the handwriting of the reviewer and named him, he relented and said I was correct! I called the reviewer and he was generous enough to spend a wonderful hour on the phone with me discussing the paper. The paper was published with great consideration given to his ideas, much to its betterment. Now that's a reviewer whose interest is in improving the paper and helping the author, not just showing how smart he is or slapping down a junior colleague. The AGU motto,“unselfish cooperation in research,” can be well exemplified by those who wish to help rather than to tear down.

Protecting genomic sequence anonymity with generalization lattices.

PubMed

Malin, B A

2005-01-01

Current genomic privacy technologies assume the identity of genomic sequence data is protected if personal information, such as demographics, are obscured, removed, or encrypted. While demographic features can directly compromise an individual's identity, recent research demonstrates such protections are insufficient because sequence data itself is susceptible to re-identification. To counteract this problem, we introduce an algorithm for anonymizing a collection of person-specific DNA sequences. The technique is termed DNA lattice anonymization (DNALA), and is based upon the formal privacy protection schema of k -anonymity. Under this model, it is impossible to observe or learn features that distinguish one genetic sequence from k-1 other entries in a collection. To maximize information retained in protected sequences, we incorporate a concept generalization lattice to learn the distance between two residues in a single nucleotide region. The lattice provides the most similar generalized concept for two residues (e.g. adenine and guanine are both purines). The method is tested and evaluated with several publicly available human population datasets ranging in size from 30 to 400 sequences. Our findings imply the anonymization schema is feasible for the protection of sequences privacy. The DNALA method is the first computational disclosure control technique for general DNA sequences. Given the computational nature of the method, guarantees of anonymity can be formally proven. There is room for improvement and validation, though this research provides the groundwork from which future researchers can construct genomics anonymization schemas tailored to specific datasharing scenarios.

HIV / AIDS in Brazil: the private sector begins to respond.

PubMed

Margolis, M

1995-02-01

Brazil has one of the highest numbers of reported AIDS cases in the world, while an estimated 500,000 Brazilians are HIV-positive. Brazilian business and labor leaders have slowly come to realize that HIV/AIDS in Brazil can have considerably adverse effects upon the private corporate sector. Social discrimination results from ignorance. Accordingly, employees who are uninformed or misinformed about how HIV is transmitted may be afraid of HIV-positive coworkers, stigmatize them, and generally disrupt the harmony of the workplace. Corporate leaders are also concerned about the loss of productivity and the high health costs which can result from HIV/AIDS morbidity and mortality in the workplace. Business people have therefore taken action to prevent and control the spread of HIV. Companies have distributed thousands of leaflets, financed booklets on safe sex, held congresses on sexually transmitted diseases, and distributed condoms to employees. Some corporate health plans guarantee total care for employees with HIV and AIDS. Policy at Shell Brazil is to not demand the HIV testing of employees or prospective employees and to neither fire nor isolate HIV-positive workers. The company's group health plan has been strengthened to cover all costs of treating people with AIDS and money has been set aside to fund a safe sex promotion campaign. The AIDS Control and Prevention Project (AIDSCAP) is lending technical assistance to Shell and other companies in Brazil.

Comments on “Anonymous reviews”

NASA Astrophysics Data System (ADS)

Okal, Emille A.

I would like to add the triple perspective of a now-retired editor (GRL, 1993-19997), a reviewer and author to the ongoing debate in Eos about anonymous versus signed reviews.As an editor, I did not keep precise statistics, but my recollection would be that a little under (perhaps 40%) of the more than 3000 reviews I handled were signed. While some sort of "trend" expectedly existed between glowing reviews and signed ones, the correlation would probably not have passed a statistical test. By and large, my reviewers, whether or not they waived anonymity, were a professional and responsible pool, and the kind of personal and potentially unethical antagonisms described by Myrl Beck was the rare exception, rather than the rule, among anonymous reviews. The careful editor should be able to recognize this attitude in the tone and style of the review, and through comparison with other reviews of the same paper.

An unlinked anonymous survey was conducted to measure the prevalence of selected markers for HIV, hepatitis B and C infection in recruits to the UK Armed Forces to inform future screening and hepatitis B vaccination policies. During 2007, nearly 14 000 left-over samples taken from new recruits for blood typing were collected, unlinked from identifiers and anonymously tested for HIV, hepatitis C and current and past cleared hepatitis B infection. Overall, serological evidence of HIV and hepatitis C was found in 0·06% and 0·06% of recruits, respectively. Evidence of past cleared and current hepatitis B infection was found in 3·63% and 0·37% of recruits, respectively. Overall, prevalence rates were broadly consistent with UK population estimates of infection. However, HIV and hepatitis B prevalence was higher in recruits of African origin than in those from the UK (P<0·0001). Screening for these infections is an option that could be considered for those entering Services from high-prevalence countries.

Today's advanced scenario where each information is available in one click, data security is the main aspect. Individual information which sometimes needs to be hiding is easily available using some tricks. Medical information, income details are needed to be kept away from adversaries and so, are stored in private tables. Some publicly released information contains zip code, sex, birth date. When this released information is linked with the private table, adversary can detect the whole confidential information of individuals or respondents, i.e. name, medical status. So to protect respondents identity, a new concept k-anonymity is used which means each released record has at least (k-1) other records in the release whose values are distinct over those fields that appear in the external data. K-anonymity can be achieved easily in case of single sensitive attributes i.e. name, salary, medical status, but it is quiet difficult when multiple sensitive attributes are present. Generalization and Suppression are used to achieve k-anonymity. This paper provides a formal introduction of k-anonymity and some techniques used with it l-diversity, t-closeness. This paper covers k-anonymity model and the comparative study of these concepts along with a new proposed concept for multiple sensitive attributes.

Background Women in South Africa are at particularly high-risk for HIV infection and are dependent on their male partners' use of condoms for sexual risk reduction. However, many women are afraid to discuss condoms with male partners, placing them at higher risk of HIV infection. Purpose To examine the association between fear of condom negotiation with HIV testing and transmission risk behaviors, including alcohol use and sexual risks among South African women. Method Women (N = 1333) residing in a primarily Xhosa-speaking African township in Cape Town and attending informal alcohol-serving venues (shebeens) completed anonymous surveys. Logistic regression was used to test the hypothesis that fear of condom negotiation would be associated with increased risk for HIV. Results Compared to women who did not fear condom negotiation, those who did were significantly less likely to have been tested for HIV, were more likely to have experienced relationship abuse, and to report more alcohol use and more unprotected sex. Conclusions For women in South Africa, fear of condom negotiation is related to higher risk of HIV. HIV prevention efforts, including targeted HIV counseling and testing, must directly address gender issues. PMID:23056211

A Mechanism for Anonymous Credit Card Systems

Tamura, Shinsuke; Yanase, Tatsuro

This paper proposes a mechanism for anonymous credit card systems, in which each credit card holder can conceal individual transactions from the credit card company, while enabling the credit card company to calculate the total expenditures of transactions of individual card holders during specified periods, and to identify card holders who executed dishonest transactions. Based on three existing mechanisms, i.e. anonymous authentication, blind signature and secure statistical data gathering, together with implicit transaction links proposed here, the proposed mechanism enables development of anonymous credit card systems without assuming any absolutely trustworthy entity like tamper resistant devices or organizations faithful both to the credit card company and card holders.

Introduction HIV stigma is a contributing factor to poor patient outcomes. Although HIV stigma has been documented, its impact on patient well-being in the southern US is not well understood. Methods Thirty-two adults participated in cognitive interviews after completing the Berger HIV or the Van Rie stigma scale. Participant responses were probed to ensure the scales accurately measured stigma and to assess the impact stigma had on behavior. Results Three main themes emerged regarding HIV stigma: (1) negative attitudes, fear of contagion, and misperceptions about transmission; (2) acts of discrimination by families, friends, health care providers, and within the workplace; and (3) participants’ use of self-isolation as a coping mechanism. Overwhelming reluctance to disclose a person’s HIV status made identifying enacted stigma with a quantitative scale difficult. Discussion Fear of discrimination resulted in participants isolating themselves from friends or experiences to avoid disclosure. Participant unwillingness to disclose their HIV status to friends and family could lead to an underestimation of enacted HIV stigma in quantitative scales. PMID:23950897

Data Retention and Anonymity Services

Berthold, Stefan; Böhme, Rainer; Köpsell, Stefan

The recently introduced legislation on data retention to aid prosecuting cyber-related crime in Europe also affects the achievable security of systems for anonymous communication on the Internet. We argue that data retention requires a review of existing security evaluations against a new class of realistic adversary models. In particular, we present theoretical results and first empirical evidence for intersection attacks by law enforcement authorities. The reference architecture for our study is the anonymity service AN.ON, from which we also collect empirical data. Our adversary model reflects an interpretation of the current implementation of the EC Directive on Data Retention in Germany.

The study aimed to assess perceptions of reading room workflow and the impact separating image-interpretive and nonimage-interpretive task workflows can have on radiologist perceptions of workplace disruptions, workload, and overall satisfaction. A 14-question survey instrument was developed to measure radiologist perceptions of workplace interruptions, satisfaction, and workload prior to and following implementation of separate image-interpretive and nonimage-interpretive reading room workflows. The results were collected over 2 weeks preceding the intervention and 2 weeks following the end of the intervention. The results were anonymized and analyzed using univariate analysis. A total of 18 people responded to the preintervention survey: 6 neuroradiology fellows and 12 attending neuroradiologists. Fifteen people who were then present for the 1-month intervention period responded to the postintervention survey. Perceptions of workplace disruptions, image interpretation, quality of trainee education, ability to perform nonimage-interpretive tasks, and quality of consultations (P < 0.0001) all improved following the intervention. Mental effort and workload also improved across all assessment domains, as did satisfaction with quality of image interpretation and consultative work. Implementation of parallel dedicated image-interpretive and nonimage-interpretive workflows may improve markers of radiologist perceptions of workplace satisfaction.

2014-01-01

Electronic medical records (EMR) and treatment plans are used in research on patient outcomes and radiation effects. In many situations researchers must remove protected health information (PHI) from EMRs. The literature contains several studies describing the anonymization of generic Digital Imaging and Communication in Medicine (DICOM) files and DICOM image sets but no publications were found that discuss the anonymization of DICOM radiation therapy plans, a key component of an EMR in a cancer clinic. In addition to this we were unable to find a commercial software tool that met the minimum requirements for anonymization and preservation of data integrity for radiation therapy research. The purpose of this study was to develop a prototype software code to meet the requirements for the anonymization of radiation therapy treatment plans and to develop a way to validate that code and demonstrate that it properly anonymized treatment plans and preserved data integrity. We extended an open-source code to process all relevant PHI and to allow for the automatic anonymization of multiple EMRs. The prototype code successfully anonymized multiple treatment plans in less than 1 minute per patient. We also tested commercial optical character recognition (OCR) algorithms for the detection of burned-in text on the images, but they were unable to reliably recognize text. In addition, we developed and tested an image filtering algorithm that allowed us to isolate and redact alpha-numeric text from a test radiograph. Validation tests verified that PHI was anonymized and data integrity, such as the relationship between DICOM unique identifiers (UID) was preserved. PMID:25147130

2015-08-01

A documentary film on HIV was developed based on social cognitive theory and entertainment educational methods in an effort to increase awareness and encourage protective behavior change related to HIV among older adults. The documentary includes perspectives from racial- or ethnic-minority older adults who are living with HIV and those of health care providers, and was screened in several venues. Authors of this article conducted thematic content analysis of anonymous, written, open-ended responses from 341 film viewers (clinicians and laypeople) who described what they learned about HIV after viewing the film. Four key themes emerged from the analysis: (1) increased awareness about the epidemiology of HIV among older, minority groups and about sexuality among older people; (2) improved general HIV knowledge, including risk reduction strategies and details about HIV testing; (3) awareness of lack of sexual health education among health care providers, and that a call to action is needed; and (4) awareness that HIV reinfection can occur in certain circumstances with people who are already infected. Findings suggest that an educational documentary can be used to effectively increase awareness and knowledge about the impact of HIV among minority older adults, and may also encourage HIV prevention action steps by providers.

Although researchers have examined barriers to implementing evidence-based practice (EBP) at the level of the individual, little is known about the effects workplaces have on speech-language pathologists' implementation of EBP. The aim of this study was to examine the impact of workplace factors on the use of EBP amongst speech-language pathologists who work with children with Autism Spectrum Disorder (ASD). This study sought to (a) explore views about EBP amongst speech-language pathologists who work with children with ASD, (b) identify workplace factors which, in the participants' opinions, acted as barriers or enablers to their provision of evidence-based speech-language pathology services, and (c) examine whether or not speech-language pathologists' responses to workplace factors differed based on the type of workplace or their years of experience. A total of 105 speech-language pathologists from across Australia completed an anonymous online questionnaire. The results indicate that, although the majority of speech-language pathologists agreed that EBP is necessary, they experienced barriers to their implementation of EBP including workplace culture and support, lack of time, cost of EBP, and the availability and accessibility of EBP resources. The barriers reported by speech-language pathologists were similar, regardless of their workplace (private practice vs organization) and years of experience.

Anonymity of donors or recipients in living-donor transplantation is a complex issue and practice varies widely. There are compelling arguments for maintaining anonymity of both parties before unspecified donor transplantation and specified indirect transplantation. After transplantation, there are still good reasons to avoid disclosure of identities. Although anonymity could be lifted if both parties explicitly request it, there are significant, potentially negative consequences of such an approach. Both donor and recipient should be counseled regarding these, and transplant teams should consider the considerable financial and psychosocial costs if problems are encountered as a result of contact. Given the recent rise in the number of unspecified living-donor transplants and through paired exchange schemes, it is vital that data are collected regarding the effects of maintaining or revoking anonymity after transplantation.

Anonymous, Yet Trustworthy Auctions

NASA Astrophysics Data System (ADS)

Chanda, Prasit Bikash; Naessens, Vincent; de Decker, Bart

An auction is an inevitable market mechanism to setup prices of goods or services in a competitive and dynamic environment. Anonymity of bidders is required to conceal their business strategies from competitors. However, it is also essential to provide the seller guarantees that a bidder is trustworthy and competent enough to perform certain tasks (e.g transports). This paper proposes an auction protocol where bidders will participate anonymously, yet prove to be trustworthy and competent and can be held accountable towards auctioneers and sellers. Moreover, the protocol introduces promises, bonuses and compensations to ensure the best price for the sellers, extra profit for bidders and opportunities for newcomers in the business. It also handles ties, and copes with last minute bidding. Finally, the auction’s fair proceedings and outcome can be verified by everyone.

2016-01-01

Background and objective: There is an increasing desire to share de-identified electronic health records (EHRs) for secondary uses, but there are concerns that clinical terms can be exploited to compromise patient identities. Anonymization algorithms mitigate such threats while enabling novel discoveries, but their evaluation has been limited to single institutions. Here, we study how an existing clinical profile anonymization fares at multiple medical centers. Methods: We apply a state-of-the-art k-anonymization algorithm, with k set to the standard value 5, to the International Classification of Disease, ninth edition codes for patients in a hypothyroidism association study at three medical centers: Marshfield Clinic, Northwestern University, and Vanderbilt University. We assess utility when anonymizing at three population levels: all patients in 1) the EHR system; 2) the biorepository; and 3) a hypothyroidism study. We evaluate utility using 1) changes to the number included in the dataset, 2) number of codes included, and 3) regions generalization and suppression were required. Results: Our findings yield several notable results. First, we show that anonymizing in the context of the entire EHR yields a significantly greater quantity of data by reducing the amount of generalized regions from ∼15% to ∼0.5%. Second, ∼70% of codes that needed generalization only generalized two or three codes in the largest anonymization. Conclusions: Sharing large volumes of clinical data in support of phenome-wide association studies is possible while safeguarding privacy to the underlying individuals. PMID:26567325

This article utilizes data from the Equal Employment Opportunity Commission's Integrated Mission System database to document the levels of employment discrimination involving individuals with HIV/AIDS. The researchers explore the theory that the nature of HIV/AIDS related employment discrimination is rooted in deeper stigmatization than discrimination against other disability groups. Researchers compare and contrast key demographic characteristics of Charging Parties and Respondents involved in HIV/AIDS related allegations of discrimination and their proportion of EEOC merit resolutions to those of persons with other physical, sensory, and neurological impairments. Findings indicate that, in contrast to the general disability group, HIV/AIDS was more likely to be male, ethnic minorities, between the ages of 25-44, in white collar jobs, in the South and West and to work for businesses with 15 to 100 employees. Additionally, the allegations in HIV/AIDS were more likely to receive merit resolution from the EEOC by a large difference of ten percent.

University students and HIV in Namibia: an HIV prevalence survey and a knowledge and attitude survey

Background With an overall adult HIV prevalence of 15.3%, Namibia is facing one of the largest HIV epidemics in Africa. Young people aged 20 to 34 years constitute one of the groups at highest risk of HIV infection in Namibia. However, little is known about the impact of HIV on this group and its access to healthcare. The purpose of this study was to estimate HIV prevalence, to assess the knowledge of and attitudes towards HIV/AIDS, and to assess access to healthcare among university students in Namibia. Methods We assessed HIV/AIDS knowledge and attitudes, HIV prevalence and access to healthcare among students at the Polytechnic of Namibia and the University of Namibia. HIV prevalence was tested through anonymous oral fluid-based tests. Results Half (n = 2790/5568) of the university students and 45% (n = 2807/6302) of the Polytechnic students participated in the knowledge and attitudes surveys. HIV/AIDS knowledge was reasonable, except for misperceptions about transmission. Awareness of one's own HIV status and risks was low. In all, 55% (n = 3055/5568) of university students and 58% (n = 3680/6302) of Polytechnic students participated in the HIV prevalence survey; 54 (1.8%) university students and 103 (2.8%) Polytechnic students tested HIV positive. Campus clinics were not the major providers of healthcare to the students. Conclusions Meaningful strategies addressing the gap between knowledge, attitude and young people's perception of risk of HIV acquisition should be implemented. HIV prevalence among Namibian university students appears relatively low. Voluntary counselling and testing should be stimulated. Efforts should be made to increase access to healthcare through the campus clinics. PMID:22353579

HIV-discordant gay male couples may play an important role in HIV-transmissions. This cross-sectional study compared the knowledge, attitudes and sexual behaviors of HIV-uninfected gay men, between those in HIV-discordant and those in HIV-concordant steady relationships. Anonymous questionnaires were distributed electronically in designated gay-related internet sites and in AIDS-clinics in 2015. The dependent variable was defined as a steady relationship of an HIV-uninfected man with an HIV-infected partner. Risky sexual behavior was defined as unprotected anal intercourse (UAI) with a sex partner whose HIV-status was either positive or unknown. Of 2,319 responders, 460 (20%) were HIV-uninfected gay men in steady relationships, of whom 72 were in HIV-discordant relationships and 388 were in HIV-concordant relationships. Those in HIV-discordant relationships presented better established knowledge regarding HIV-transmission, more lenient attitudes regarding UAI, and reported being involved in riskier sexual behavior, both within and outside their steady relationship compared to men in HIV-concordant relationships. UAI was performed by 48% of the HIV-discordant couples and was associated with the use of sero-positioning strategy and with achieving undetectable viral-load. These findings reflect the complexity of constant use of condoms during long-term sero-discordant relationships. Targeted interventions for HIV-prevention in HIV-discordant couples should be employed for balancing the partners' desire for intimacy and sexual pleasure in the relationship, while reducing the risk for acquiring HIV. ART: Antiretroviral therapy; PEP: Post exposure prophylaxis; PrEP: Pre exposure prophylaxis; STI: Sexually transmitted infections; UAI: Unprotected anal intercourse.

Objective To characterize HIV testing practices among men who have sex with men (MSM) in Mexico and intention to use HIV self-testing. Methods In 2012, members of one of the largest social/sexual networking websites for MSM in Latin America completed an anonymous online survey. This analysis was restricted to HIV-uninfected MSM residing in Mexico. Multivariable logistic regression models were fit to assess factors associated with HIV testing and intention to use an HIV self-test. Results Of 4,537 respondents, 70.9% reported ever having an HIV test, of whom 75.5% reported testing at least yearly. The majority (94.3%) indicated that they would use an HIV home self-test if it were available. Participants identifying as bisexual less often reported ever HIV testing compared to those identifying as gay/homosexual (aOR=0.52, 95%CI: 0.44-0.62). Having a physical exam in the past year was associated with increased ever HIV testing (aOR=4.35, 95%CI: 3.73-5.07), but associated with decreased interest in HIV self-testing (aOR=0.66, 95%CI: 0.48-0.89). Conclusions High intention to use HIV home self-testing supports the use of this method as an acceptable alternative to clinic- or hospital-based HIV testing. PMID:27020081

The objective of this study is to develop a solution to preserve security and privacy in a healthcare environment where health-sensitive information will be accessed by many parties and stored in various distributed databases. The solution should maintain anonymous medical records and it should be able to link anonymous medical information in distributed databases into a single patient medical record with the patient identity. In this paper we present a protocol that can be used to authenticate and authorize patients to healthcare services without providing the patient identification. Healthcare service can identify the patient using separate temporary identities in each identification session and medical records are linked to these temporary identities. Temporary identities can be used to enable record linkage and reverse track real patient identity in critical medical situations. The proposed protocol provides main security and privacy services such as user anonymity, message privacy, message confidentiality, user authentication, user authorization and message replay attacks. The medical environment validates the patient at the healthcare service as a real and registered patient for the medical services. Using the proposed protocol, the patient anonymous medical records at different healthcare services can be linked into one single report and it is possible to securely reverse track anonymous patient into the real identity. The protocol protects the patient privacy with a secure anonymous authentication to healthcare services and medical record registries according to the European and the UK legislations, where the patient real identity is not disclosed with the distributed patient medical records.

There is an increasing desire to share de-identified electronic health records (EHRs) for secondary uses, but there are concerns that clinical terms can be exploited to compromise patient identities. Anonymization algorithms mitigate such threats while enabling novel discoveries, but their evaluation has been limited to single institutions. Here, we study how an existing clinical profile anonymization fares at multiple medical centers. We apply a state-of-the-artk-anonymization algorithm, withkset to the standard value 5, to the International Classification of Disease, ninth edition codes for patients in a hypothyroidism association study at three medical centers: Marshfield Clinic, Northwestern University, and Vanderbilt University. We assess utility when anonymizing at three population levels: all patients in 1) the EHR system; 2) the biorepository; and 3) a hypothyroidism study. We evaluate utility using 1) changes to the number included in the dataset, 2) number of codes included, and 3) regions generalization and suppression were required. Our findings yield several notable results. First, we show that anonymizing in the context of the entire EHR yields a significantly greater quantity of data by reducing the amount of generalized regions from ∼15% to ∼0.5%. Second, ∼70% of codes that needed generalization only generalized two or three codes in the largest anonymization. Sharing large volumes of clinical data in support of phenome-wide association studies is possible while safeguarding privacy to the underlying individuals. © The Author 2015.

Opollo, Jackline G; Gray, Jennifer

2015-01-01

HIV-related stigma decreases access to HIV testing, prevention, and treatment services. Our mixed methods study explored stigma as perceived, experienced, and managed in a sample of 76 HIV-infected health care workers in Kisumu, Kenya. Stigma was quantitatively measured using the HIV/AIDS Stigma Instrument for People Living with AIDS (HASI-P). Overall, subjects experienced low stigma levels (mean = 7.88, SD = 12.90; range = 0-61), and none of the sociodemographic variables were predictive of stigma. Transcript analysis of 20 qualitative interviews revealed two negative themes (blame, lack of knowledge) and five positive themes (living positively, optimism, empathy, support, changes over time). Three themes emerged on reducing stigma (normalizing, empowerment, leading by example). Disclosure, access to treatment, stigma reduction training, workplace support groups, and awareness of an HIV workplace policy may have contributed to low stigma scores. Qualitative findings corroborated quantitative findings and corresponded to the six domains of the HASI-P. Copyright © 2015 Association of Nurses in AIDS Care. Published by Elsevier Inc.

AIDS control and the workplace: the role of occupational health services in South Africa.

PubMed

London, L

1998-01-01

AIDS interventions typically fail to address the disjuncture between private behaviors and the social determinants of HIV infection. Data from a telephone survey of manufacturing companies and a postal survey of occupational health nurses in the Western Cape, South Africa, were used to explore the possible role of occupational health services in prevention and control of AIDS. The author found limited evidence of worker involvement in AIDS programs, particularly in companies with occupational health professionals. The management of sexually transmitted diseases was incomplete. Mandatory pre-employment testing of workers for HIV was not widespread. Respondents' opinions on priorities for AIDS prevention and control reflected a preoccupation with knowledge transfer. To ensure their effectiveness, workplace AIDS programs must improve worker participation and integrate AIDS prevention in general workplace health and safety programs. In addition, education programs must develop objectives within a critical theoretical understanding of the behavioral issues relevant to AIDS prevention, and must emphasize the empowerment of women in the workplace. In the context of the present restructuring of health services in South Africa, occupational health services, using the strategies outlined, can make a major contribution to national AIDS prevention and control.

At risk, infected, and invisible: older gay men and HIV/AIDS.

PubMed

Grossman, A H

1995-01-01

Older gay men over the age of 50 have been and continue to be an invisible part of the HIV/AIDS epidemic. The reasons for this phenomenon are many, but among them are societal beliefs, myths, and stereotypes emanating from ageism and homophobia. In addition, HIV/AIDS is sometimes misdiagnosed in older adults because many of its symptoms mimic other illness that affect older people. Among the HIV risk factors of older gay men are internalized homophobia, denial of risk, alcohol and other substance use, and anonymous sexual encounters. The challenge for nurses and other providers is to reach, educate, and assist older gay men effectively in changing and maintaining safe behaviors when they are engaging in sexual and drug-using behaviors that can transmit HIV.

Wesolowski, David J.

To those scientists who haven't served as editors or associate editors of scientific journals, I can assure you that it's already too hard to find enough qualified reviewers willing to do the job without threatening them with exposure as well! So, if you want your papers to be published within a reasonable timeframe, you'll pretty much have to put up with anonymous reviews.I've been an associate editor of Geochimica et Cosmochimica Acta for 11 years and an Editorial Board member of Chemical Geology for 4. I think anonymous reviews are perfectly acceptable, but that the editor evaluating the reviews should always be identified, both to the authors and in the published manuscript. Reviewers should be permitted to request anonymity, but authors should always be instructed to specifically acknowledge in their manuscripts the contributions of those reviewers who do not request anonymity. This, in fact, might encourage more reviewers to identify themselves. I don't know about you, but it tickles me pink when I see my name in print!

  The objective of this pilot study was to identify the type of workplace violence experienced by undergraduate paramedic and midwifery students. The study used a cross-sectional methodology with the self-administered paper-based Paramedic Workplace Violence Exposure Questionnaire to elicit undergraduate paramedic and midwife responses to workplace violence whilst on clinical placements. There were 393 students eligible for inclusion in the study. A convenience sample was used. The anonymous questionnaire took 10 to 20 minutes to complete. Descriptive statistics are used to summarise the data with a two-tailed t-test used to compare groups. The main form of workplace violence was verbal abuse 18% and intimidation 17%.  There was a statistically significant difference between midwifery and paramedic students for intimidation (t (134) =-3.143, CI: -0.367 to -0.082, p=0.002) and between females and males for sexual harassment (t (134) =2.029, CI: 0.001 to 0.074, p=0.045), all other results were not statistically different. This pilot study is the first of its kind in Australia and internationally to identify exposure rates of workplace violence by undergraduate paramedic students during clinical placements and one of very few to identify midwifery students' exposure rates of workplace violence. The study identified that students were exposed to a range of workplace violence acts from verbal abuse through to sexual harassment. These findings highlight a need for investigation of workplace violence exposure of medical, nursing and allied health students during the clinical phase of their studies.

HIV Surveillance Among Pregnant Women Attending Antenatal Clinics: Evolution and Current Direction

Since the late 1980s, human immunodeficiency virus (HIV) sentinel serosurveillance among pregnant women attending select antenatal clinics (ANCs) based on unlinked anonymous testing (UAT) has provided invaluable information for tracking HIV prevalence and trends and informing global and national HIV models in most countries with generalized HIV epidemics. However, increased coverage of HIV testing, prevention of mother-to-child transmission (PMTCT), and antiretroviral therapy has heightened ethical concerns about UAT. PMTCT programs now routinely collect demographic and HIV testing information from the same pregnant women as serosurveillance and therefore present an alternative to UAT-based ANC serosurveillance. This paper reports on the evolution and current direction of the global approach to HIV surveillance among pregnant women attending ANCs, including the transition away from traditional UAT-based serosurveillance and toward new guidance from the World Health Organization and the Joint United Nations Programme on HIV/AIDS on the implementation of surveillance among pregnant women attending ANCs based on routine PMTCT program data.

Assessing business responses to HIV / AIDS in Kenya.

Roberts, M; Wangombe, J

1995-01-01

A consulting firm conducted interviews with managers of 16 businesses in 3 Kenyan cities, representatives of 2 trade unions, focus groups with workers at 13 companies, and an analysis of financial/labor data from 4 companies. It then did a needs assessment. The business types were light industry, manufacturing companies, tourism organizations, transport firms, agro-industrial and plantation businesses, and the service industry. Only one company followed all the workplace policy principles recommended by the World Health Organization and the International Labor Organization. Six businesses required all applicants and/or employees to undergo HIV testing. All their managers claimed that they would not discriminate against HIV-infected workers. Many workers thought that they would be fired if they were--or were suspected to be--HIV positive. Lack of a non-discrimination policy brings about worker mistrust of management. 11 companies had some type of HIV/AIDS education program. All the programs generated positive feedback. The main reasons for not providing HIV/AIDS education for the remaining 5 companies were: no employee requests, fears that it would be taboo, and assumptions that workers could receive adequate information elsewhere. More than 90% of all companies distributed condoms. 60% offered sexually transmitted disease diagnosis and treatment. About 33% offered counseling. Four companies provided volunteer HIV testing. Almost 50% of companies received financial or other external support for their programs. Most managers thought AIDS to be a problem mainly with manual staff and not with professional staff. Almost all businesses offered some medical benefits. The future impact of HIV/AIDS would be $90/employee/year (by 2005, $260) due to health care costs, absenteeism, retraining, and burial benefits. The annual costs of a comprehensive workplace HIV/AIDS prevention program varied from $18 to $54/worker at one company.

Moral distress and burnout in Iranian nurses: The mediating effect of workplace bullying.

Moral distress and workplace bullying are important issues in the nursing workplace that appear to affect nurse's burnout. To investigate the relationship between moral distress and burnout in Iranian nurses, as mediated by their perceptions of workplace bullying. Ethical considerations: The research was approved by the committee of ethics in research of the Urmia University of Medical Sciences. This is a correlation study using a cross-sectional design with anonymous questionnaires as study instruments (i.e. Moral Distress Scale-Revised, Maslach Burnout Inventory and The Negative Acts Questionnaire-Revised). Data were collected from 278 nurses from five teaching hospitals in Urmia, the capital of Western Azerbaijan, northwest of Iran. Structural equation modeling and bootstrapping procedures were employed to recognize the mediating role of their perceptions of workplace bullying. The mean score of moral distress, burnout, and the Negative Acts Questionnaire-Revised Scale among the participants were 91.02 ± 35.26, 79.9 ± 18.27, and 45.4 ± 15.39, respectively. The results confirmed our hypothesized model. All the latent variables of study were significantly correlated in the predicted directions. The moral distress and bullying were significant predictors of burnout. Perception of bullying partially mediated the relationship between moral distress and burnout. The mediating role of the bullying suggests that moral distress increases burnout, directly and indirectly. Nursing administrators should be conscious of the role of moral distress and bullying in the nursing workplace in increasing burnout.

Securing the anonymity of content providers in the World Wide Web

Nowadays the World Wide Web (WWW) is an established service used by people all over the world. Most of them do not recognize the fact that they reveal plenty of information about themselves or their affiliation and computer equipment to the providers of web pages they connect to. As a result, a lot of services offer users to access web pages unrecognized or without risk of being backtracked, respectively. This kind of anonymity is called user or client anonymity. But on the other hand, an equivalent protection for content providers does not exist, although this feature is desirable for many situations in which the identity of a publisher or content provider shall be hidden. We call this property server anonymity. We will introduce the first system with the primary target to offer anonymity for providers of information in the WWW. Beside this property, it provides also client anonymity. Based on David Chaum's idea of mixes and in relation to the context of the WWW, we explain the term 'server anonymity' motivating the system JANUS which offers both client and server anonymity.

The aims of this study are to assess the impact of Austria's anonymous birth law from the time relevant statistical records are available and to evaluate the use of hatches versus anonymous hospital delivery. This study is a complete census of police-reported neonaticides (1975-2012) as well as anonymous births including baby hatches in Austria during 2002-2012. The time trends of neonaticide rates, anonymous births and baby hatches were analysed by means of Poisson and logistic regression model. Predicted and observed rates were derived and compared using a Bayesian Poisson regression model. Predicted numbers of neonaticides for the period of the active awareness campaign, 2002-2004, were more than three times larger than the observed number (p = 0.0067). Of the 365 women who benefitted from this legislation, only 11.5% chose to put their babies in a baby hatch. Since the law was introduced, a significant decreasing tendency of numbers of anonymous births (p = 047) was observed, while there was significant increase of neonaticide rates (p = 0.0001). The implementation of the anonymous delivery law is associated with a decrease in the number of police-reported neonaticides. The subsequent significantly decreasing numbers of anonymous births with an accompanying increase of neonaticides represents additional evidence for the effectiveness of the measure.

"HIV is irrelevant to our company": everyday practices and the logic of relationships in HIV/AIDS management by Japanese multinational corporations in northern Thailand.

PubMed

Michinobu, Ryoko

2009-03-01

Multinational corporations (MNCs) are important participants in workplace initiatives on HIV/AIDS as they collaborate with international organizations to globally promote various policies and guidelines. To date, MNCs have enacted the majority of such initiatives in North America, Europe and South Africa, but we have little information on how MNCs elsewhere, especially in Japan, have responded to the issue of HIV/AIDS in the workplace. This study examines the actual on the ground situation of HIV/AIDS management in Japanese MNCs, specifically investigating everyday corporate practices in the context of internal interactions and relationships and the resulting practices and outlook concerning HIV/AIDS. It is based on a secondary analysis of ethnographic case studies conducted in 10 Japanese-affiliated companies in northern Thailand. Japanese managers, Thai managers and ordinary Thai workers all considered HIV/AIDS to be "irrelevant" to their company and/or themselves. HIV/AIDS measures in the companies were limited to provision of information. This perception and management of HIV/AIDS developed from their everyday interactions governed by the logic of relationships in the companies. In these interactions, they categorized others based on their ascriptive status, primarily based on class, ethnicity and nationality. They sought scapegoat groups that were lower than them in the class- and ethnicity/nationality-based hierarchical system, and cast the risk of HIV infection upon the scapegoat groups, thus reducing their own sense of risk. The paper shows that the relational logic, not ideals or principles, influences their views of and actions concerning HIV/AIDS management in the companies. This is why Japanese companies are unable to deal with HIV/AIDS in terms of international policies and guidelines that are based on the logic of human rights and the logic of business principles. The results suggest a need for international policymakers to pay more attention to

Some studies suggest that a workplace prevention programme could reduce health inequalities related to education level and improve the health status of the employees. The objective of the study was to demonstrate the advantages for a company to implement a health prevention programme in the workplace in order to: 1-improve health literacy 2 - change health-related behaviours 3-improve the company image. A "before - after" methodology was used in a population of 2153 employees of three companies. Three areas of prevention were considered: nutrition, physical activity and prevention of back pain. The successive steps of the EBS programme included general communication, group workshops and individual coaching. Data collection was carried out using anonymous questionnaires sent by e-mail. A global assessment was performed based on the companies' pooled data, with separate analysis according to the steps of the programme. The programme mobilized employees with participation rates ranging from 25% to 45.5%. After completion of the full programme, 77.5% of respondents reported an improvement of their health knowledge versus 50.3% of those who only received general communication. Behavioural modification was observed, especially in the fields of nutrition and back pain.. EBS can be considered to be a vector of the company image for almost 7 out of 10 employees. A health prevention education programme provided by the company in the workplace mobilizes employees and contributes to improvement of health knowledge and behaviour change. All approaches tested were important and applicable to various types of companies or workers.

Fear of breaches in confidentiality and HIV-related stigma in the workplace have been shown to be primary concerns and potential barriers to uptake of HIV testing and treatment by health care workers (HCWs) at the Occupational Health Unit (OHU). In a context of human resource shortages, it is essential to investigate potential ways of reducing HIV-related stigma and promoting confidentially in the workplace. Using Structural Equation Modelling (SEM), baseline data of the "HIV and TB Stigma among Health Care Workers Study" (HaTSaH Study) for 818 respondents has been analysed to investigate (1) whether bottom-up stigma-reduction activities already occur; and (2) whether such grassroots actions can reduce the fear of breaches in confidentiality and HIV-related stigma - and thus indirectly stimulate the uptake of HIV services at the OHU. Results (aim 1) illustrate the occurrence of existing activities aiming to reduce HIV-related stigma, such as HCWs giving extra support to HIV positive co-workers and educating co-workers who stigmatise HIV. Furthermore, results of the SEM analysis (aim 2) show that the Fighting-stigma factor has a significant negative effect on HIV-related stigma and a significant positive effect on Confidentiality. Results show that the latent fighting-stigma factor has a significant positive total indirect effect on the use of HIV testing, CD4 cell count and HIV-treatment at the OHU. The findings reveal that the fear of breaches in confidentiality and HIV-related stigma can be potential barriers to the uptake of occupationally-based HIV services. However, results also show that a bottom-up climate of fighting HIV-related stigma can stimulate confidentiality in the workplace and diminish the negative effect of HIV-related stigma - resulting in an overall positive effect on the reported willingness to access occupationally-based HIV services.

To investigate the interrelationships between workplace violence, thriving at work and turnover intention among Chinese nurses and to explore the action mechanism among these variables. Workplace violence is a dangerous occupational hazard globally, and it is pervasive in the health service industry. As a corollary, workplace violence may produce many negative outcomes among nursing staff. Consequently, it hinders nurses' professional performance and reduces nursing quality. A cross-sectional online survey was conducted. A total of 1,024 nurses from 26 cities in China were recruited from February-May 2016. An anonymous questionnaire was used in this survey. Participants' completed data were collected using a demographics form and a 26-item questionnaire consisting of scales addressing workplace violence, thriving at work, job satisfaction, subjective well-being and turnover intention. To evaluate multivariate relationships, some multiple linear hierarchical regression analyses were performed. Workplace violence significantly negatively influenced nurses' job satisfaction and thriving at work, and significantly positively influenced nurses' turnover intention. Job satisfaction significantly predicted thriving at work and turnover intention. Job satisfaction not only fully mediated the relationship between workplace violence and thriving at work, but also partially mediated the relationship between workplace violence and turnover intention. Subjective well-being moderated the relationship between workplace violence and job satisfaction and the relationship between workplace violence and nurses' turnover intention. Adverse effects of workplace violence were demonstrated in this study. Decreases in job satisfaction were a vital mediating factor. The moderating effect of subjective well-being was helpful in reducing the harm of workplace violence to nurses and in decreasing their turnover intention. Workplace violence and its negative impact on nursing work should not

Drivers of workplace discrimination against people with disabilities: the utility of Attribution Theory.

The purpose of this paper was to determine what drives workplace discrimination against people with disabilities. These findings are then compared to available literature on attribution theory, which concerns itself with public perceptions of the controllability and stability of various impairments. The sample included 35,763 allegations of discriminations filed by people with disabilities under the employment provisions of the Americans with Disabilities Act. Group A included impairments deemed by Corrigan et al. [1988] to be uncontrollable but stable: visual impairment (representing 13% of the total allegations in this study), cancer (12%), cardiovascular disease (19%), and spinal cord injuries (5%). The controllable but unstable impairments in group B included depression (38%), schizophrenia (2%), alcohol and other drug abuse (4%), and HIV/AIDS (7%). The Equal Employment Opportunity Commission had resolved all allegations in terms of merit Resolutions (a positive finding of discrimination) and Resolutions without merit. Allegations of workplace discrimination were found to center mainly on hiring, discharge, harassment, and reasonable accommodation issues. Perceived workplace discrimination (as measured by allegations filed with EEOC) does occur at higher levels in Group B, especially when serious issues involving discharge and disability harassment are involved. With the glaring exception of HIV/AIDS, however, actual discrimination (as measured by EEOC merit Resolutions) occurs at higher levels for Group A.

Predictors of anonymous cyber aggression: the role of adolescents' beliefs about anonymity, aggression, and the permanency of digital content.

Little attention has been given to whether adolescents' beliefs about anonymity and their normative beliefs about cyber aggression jointly increase their perpetration of cyber aggression. To this end, the present longitudinal study examined the moderating influence of these variables on the relationships among adolescents' attitudes toward the permanency of digital content, confidence with not getting caught, and anonymous cyber aggression (ACA) assessed 1 year later (Time 2). These associations were examined among 274 7th and 8th graders and through five technologies, including social networking sites (SNS), e-mail, instant messenger (IM), mobile phones, and chatrooms. Findings indicated that increases in Time 2 ACA and attitudes toward the permanency of digital content were more strongly related when adolescents reported greater confidence with not getting caught and higher normative beliefs concerning cyber aggression through SNS and mobile phones. In addition, higher levels of attitudes toward the permanency of digital content, confidence with not getting caught, beliefs about anonymity, and normative beliefs regarding cyber aggression were related to greater Time 2 ACA through e-mail, IM, and chatrooms. All findings are discussed in the context of adolescents' positive attitudes toward ACA, and an appeal for additional research is made to understand more about anonymity in cyberspace.

The objective of this study was to characterize HIV testing practices among men who have sex with men in Mexico and intention to use HIV self-testing. In 2012, members of one of the largest social/sexual networking websites for men who have sex with men in Latin America completed an anonymous online survey. This analysis was restricted to HIV-uninfected men who have sex with men residing in Mexico. Multivariable logistic regression models were fit to assess factors associated with HIV testing and intention to use a HIV self-test. Of 4537 respondents, 70.9% reported ever having a HIV test, of whom 75.5% reported testing at least yearly. The majority (94.3%) indicated that they would use a HIV home self-test if it were available. Participants identifying as bisexual less often reported ever HIV testing compared to those identifying as gay/homosexual (adjusted odds ratio = 0.52, 95% confidence interval: 0.44-0.62). Having a physical exam in the past year was associated with increased ever HIV testing (adjusted odds ratio = 4.35, 95% confidence interval: 3.73-5.07), but associated with decreased interest in HIV self-testing (adjusted odds ratio = 0.66, 95% confidence interval: 0.48-0.89). The high intention to use HIV home self-testing supports the use of this method as an acceptable alternative to clinic- or hospital-based HIV testing.

What Does Anonymization Mean? DataSHIELD and the Need for Consensus on Anonymization Terminology.

PubMed

Wallace, Susan E

2016-06-01

Anonymization is a recognized process by which identifiers can be removed from identifiable data to protect an individual's confidentiality and is used as a standard practice when sharing data in biomedical research. However, a plethora of terms, such as coding, pseudonymization, unlinked, and deidentified, have been and continue to be used, leading to confusion and uncertainty. This article shows that this is a historic problem and argues that such continuing uncertainty regarding the levels of protection given to data risks damaging initiatives designed to assist researchers conducting cross-national studies and sharing data internationally. DataSHIELD and the creation of a legal template are used as examples of initiatives that rely on anonymization, but where the inconsistency in terminology could hinder progress. More broadly, this article argues that there is a real possibility that there could be possible damage to the public's trust in research and the institutions that carry it out by relying on vague notions of the anonymization process. Research participants whose lack of clear understanding of the research process is compensated for by trusting those carrying out the research may have that trust damaged if the level of protection given to their data does not match their expectations. One step toward ensuring understanding between parties would be consistent use of clearly defined terminology used internationally, so that all those involved are clear on the level of identifiability of any particular set of data and, therefore, how that data can be accessed and shared.

Knowledge of HIV/AIDS and attitudes towards people living with HIV among the general staff of a public university in Malaysia.

Stigma and discrimination towards people living with HIV have been widely documented, and have extended their impact into the workplace. Stigmatising attitudes towards people living with HIV (PLHIV) in the workplace significantly hinder HIV prevention efforts and indirectly affect national development. This cross-sectional study was designed to determine the level of knowledge about HIV and AIDS and assess attitudes towards PLHIV among the general staff of Universiti Putra Malaysia (UPM), as well as to identify factors that are associated with it. Self-administered questionnaires were posted to a total of 344 general staff from six randomly selected faculties, and they were a given a week to return the questionnaires. The response rate was 38%. Data were analysed using Pearson's correlation, independent t-test and multiple linear regression. The respondents showed a considerably high level of knowledge about HIV/AIDS (mean knowledge score of 15.57+/-1.93 out of 18 points) although there were some misconceptions (N=129). Likert scale responses to 20 attitude statements revealed that respondents generally had moderately positive attitudes toward PLHIV (average score of 69.65+/-10.08 out of 100 points). Attitudes were inconsistent when it involved direct contact and interaction with PLHIV. Factors significantly associated with level of knowledge and attitudes included age, education and income. There was no difference in mean score for knowledge and attitudes by gender. Further efforts are necessary to improve attitudes of the general staff towards PLHIV, particularly in areas of direct contact with PLHIV.

Mediated learning in the workplace: student perspectives on knowledge resources.

Shanahan, Madeleine

2015-01-01

In contemporary clinical practice, student radiographers can use many types of knowledge resources to support their learning. These include workplace experts, digital and nondigital information sources (eg, journals, textbooks, and the Internet), and electronic communication tools such as e-mail and social media. Despite the range of knowledge tools available, there is little available data about radiography students' use of these resources during clinical placement. A 68-item questionnaire was distributed to 62 students enrolled in an Australian university undergraduate radiography program after they completed a clinical placement. Researchers used descriptive statistics to analyze student access to workplace experts and their use of digital and nondigital information sources and electronic communication tools. A 5-point Likert scale (1 = very important; 5 = not important) was used to assess the present importance and perceived future value of knowledge tools for workplace learning. Of the 53 students who completed and returned the questionnaire anonymously, most rely on the knowledge of practicing technologists and on print and electronic information sources to support their learning; some students also use electronic communication tools. Students perceive that these knowledge resources also will be important tools for their future learning as qualified health professionals. The findings from this study present baseline data regarding the value students attribute to multiple knowledge tools and regarding student access to and use of these tools during clinical placement. In addition, most students have access to multiple knowledge tools in the workplace and incorporate these tools simultaneously into their overall learning practice during clinical placement. Although a range of knowledge tools is used in the workplace to support learning among student radiographers, the quality of each tool should be critically analyzed before it is adopted in practice

Improved partner notification (PN) after HIV diagnosis could help control HIV among men who have sex with men (MSM). However, there is little evidence exploring what this experience is like for Australian MSM and how achievable it is in the era of the Internet and smartphones. Fifteen of 39 invited MSM recently diagnosed with HIV undertook a semistructured interview about PN. Interviews were thematically analyzed using a combined deductive/inductive approach. Three main themes arose: fear of PN and HIV disclosure, partners' unexpected reactions, and the need for more patient support. MSM found PN difficult and uncomfortable and described fear about potential repercussions of PN; however, they felt it was the right thing to do. Regular partners were more likely to be notified, and in person, because of the availability of contact information but more notably because of a sense of moral responsibility. Men commonly had few contact details for casual partners and preferred PN strategies that allowed them to remain anonymous, largely reflecting the reasons for and ways in which they met casual partners: online or through apps and predominantly for once-off, anonymous sex. Most described unexpected positive responses from partners who were contacted personally by the men. Our study also showed that participants required professional support to carry out PN, especially with casual partners, as well as support around understanding the implications of and treatments relating to being HIV positive. PN could be improved by offering more options that allow the index patient to remain anonymous, particularly when notifying casual partners.

This study investigates associations between psychological distress and workplace accidents, workplace failures and workplace successes. The Health and Work Performance Questionnaire (HPQ) was distributed to employees of 58 large employers. A total of 60,556 full-time employees were eligible for analysis. The HPQ probed whether the respondent had, in the past 30-days, a workplace accident, success or failure ("yes" or "no"). Psychological distress was quantified using the Kessler 6 (K6) scale and categorised into low, moderate and high psychological distress. Three binomial logistic regressions were performed with the dependent variables being workplace accident, success or failure. Covariates in the models were K6 category, gender, age, marital status, education level, job category, physical health and employment sector. Accounting for all other variables, moderate and high psychological distress significantly (P < 0.0001) increased the odds ratio (OR) for a workplace accident to 1.4 for both levels of distress. Moderate and high psychological distress significantly (P < 0.0001) increased the OR (OR = 2.3 and 2.6, respectively) for a workplace failure and significantly (P < 0.0001) decreased the OR for a workplace success (OR = 0.8 and 0.7, respectively). Moderate and high psychological distress increase the OR's for workplace accidents work failures and decrease the OR of workplace successes at similar levels. As the prevalence of moderate psychological distress is approximately double that of high psychological distress moderate distress consequentially has a greater workplace impact.

How anonymous is 'anonymous'? Some suggestions towards a coherent universal coding system for genetic samples.

PubMed

Schmidt, Harald; Callier, Shawneequa

So-called 'anonymous' tissue samples are widely used in research. Because they lack externally identifying information, they are viewed as useful in reconciling conflicts between the control, privacy and confidentiality interests of those from whom the samples originated and the public (or commercial) interest in carrying out research, as reflected in 'consent or anonymise' policies. High level guidance documents suggest that withdrawal of consent and samples and the provision of feedback are impossible in the case of anonymous samples. In view of recent developments in science and consumer-driven genomics the authors argue that such statements are misleading and only muddle complex ethical questions about possible entitlements to control over samples. The authors therefore propose that terms such as 'anonymised', 'anonymous' or 'non-identifiable' be removed entirely from documents describing research samples, especially from those aimed at the public. This is necessary as a matter of conceptual clarity and because failure to do so may jeopardise public trust in the governance of large scale databases. As there is wide variation in the taxonomy for tissue samples and no uniform national or international standards, the authors propose that a numeral-based universal coding system be implemented that focuses on specifying incremental levels of identifiability, rather than use terms that imply that the reidentification of research samples and associated actions are categorically impossible.

Despite the major benefits of antiretroviral therapy on survival during HIV infection, there is an increasing need to manage symptoms and side effects during long-term drug therapy. Cannabis has been reported anecdotally as being beneficial for a number of common symptoms and complications in HIV infections, for example, poor appetite and neuropathy. This study aimed to investigate symptom management with cannabis. Following Ethics Committee approval, HIV-positive individuals attending a large clinic were recruited into an anonymous cross-sectional questionnaire study. Up to one-third (27%, 143/523) reported using cannabis for treating symptoms. Patients reported improved appetite (97%), muscle pain (94%), nausea (93%), anxiety (93%), nerve pain (90%), depression (86%), and paresthesia (85%). Many cannabis users (47%) reported associated memory deterioration. Symptom control using cannabis is widespread in HIV outpatients. A large number of patients reported that cannabis improved symptom control.

AIB-OR: improving onion routing circuit construction using anonymous identity-based cryptosystems.

The rapid growth of Internet applications has made communication anonymity an increasingly important or even indispensable security requirement. Onion routing has been employed as an infrastructure for anonymous communication over a public network, which provides anonymous connections that are strongly resistant to both eavesdropping and traffic analysis. However, existing onion routing protocols usually exhibit poor performance due to repeated encryption operations. In this paper, we first present an improved anonymous multi-receiver identity-based encryption (AMRIBE) scheme, and an improved identity-based one-way anonymous key agreement (IBOWAKE) protocol. We then propose an efficient onion routing protocol named AIB-OR that provides provable security and strong anonymity. Our main approach is to use our improved AMRIBE scheme and improved IBOWAKE protocol in onion routing circuit construction. Compared with other onion routing protocols, AIB-OR provides high efficiency, scalability, strong anonymity and fault tolerance. Performance measurements from a prototype implementation show that our proposed AIB-OR can achieve high bandwidths and low latencies when deployed over the Internet.

Best practices: a review of company activity on HIV / AIDS in South Africa.

This article presents the 1998 survey results conducted by the Health Economics and HIV/AIDS Research Division of the University of Natal in South Africa with the goal of documenting the best practices of managing HIV/AIDS in the workplace. The five key areas of the study are: HIV prevention; managing ill health; human resource development and industrial relations; employee benefits and survivor support; monitoring and planning for change in the workplace. The research comprised 14 companies used during the case studies. A few notable cases were observed among companies attempting to create awareness about HIV/AIDS. The Best Practice Survey highlighted issues about the private sectors in South Africa and their HIV management. First, companies conceptualize AIDS as either a health or poverty problem. Second, the environment is affected by the hazards of economic downturns, labor action, and economic inflation while the AIDS problem is neglected. Third, indirect costs were not considered and most companies feel that the conversion to a defined contribution arrangement compensates against escalating payouts for benefits. Fourth, long-term plans of the companies did not utilize the ill health statistics for the past 5 years.

New forms of HIV/AIDS therapy require new surveillance instruments to meet shifting public health demands. The Clinical Surveillance of HIV Disease (ClinSurv HIV) project was established in 1999 as a collaboration between major HIV treatment centres in Germany and the Robert Koch Institute (RKI). The project contributes to national HIV surveillance and focuses on the changing epidemiology of HIV/AIDS after the introduction of new therapies in 1995. ClinSurv HIV is designed as an open multicentre observational cohort study of HIV-infected patients. Anonymized data on diagnoses, treatment and laboratory parameters are collected in a standardized format. Data are currently sampled biannually via 11 centres specializing in HIV diagnosis and care within the legal framework of the German Protection against Infection Act [Infektionsschutzgesetz (IfSG)]. A total of 14874 patients were enrolled in the study by 30 June 2009. Of these, 10221 patients (68.7%) were enrolled after 1 January 1999 and 6006 patients (40.4%) were known to have been diagnosed as positive for HIV before 1999. Evaluation indicators, such as the number of newly enrolled patients per half-year period, loss to follow-up, completeness of data per case, availability of data per possible clinical contact, and internal quality control parameters, show a very stable evolution in the cohort, which although open, can be observed. Comparison with the national HIV surveillance data suggests a high degree of representativeness according to major demographic variables. Bearing in mind the obvious strengths and weaknesses discussed, the German ClinSurv HIV cohort provides a broad range of research opportunities in the field of HIV/AIDS both within Germany and in international collaborative research.

Stationary Anonymous Sequential Games with Undiscounted Rewards.

PubMed

Więcek, Piotr; Altman, Eitan

Stationary anonymous sequential games with undiscounted rewards are a special class of games that combine features from both population games (infinitely many players) with stochastic games. We extend the theory for these games to the cases of total expected reward as well as to the expected average reward. We show that in the anonymous sequential game equilibria correspond to the limits of those of related finite population games as the number of players grows to infinity. We provide examples to illustrate our results.

Connection anonymity analysis in coded-WDM PONs

NASA Astrophysics Data System (ADS)

Sue, Chuan-Ching

2008-04-01

A coded wavelength division multiplexing passive optical network (WDM PON) is presented for fiber to the home (FTTH) systems to protect against eavesdropping. The proposed scheme applies spectral amplitude coding (SAC) with a unipolar maximal-length sequence (M-sequence) code matrix to generate a specific signature address (coding) and to retrieve its matching address codeword (decoding) by exploiting the cyclic properties inherent in array waveguide grating (AWG) routers. In addition to ensuring the confidentiality of user data, the proposed coded-WDM scheme is also a suitable candidate for the physical layer with connection anonymity. Under the assumption that the eavesdropper applies a photo-detection strategy, it is shown that the coded WDM PON outperforms the conventional TDM PON and WDM PON schemes in terms of a higher degree of connection anonymity. Additionally, the proposed scheme allows the system operator to partition the optical network units (ONUs) into appropriate groups so as to achieve a better degree of anonymity.

Persona: Network Layer Anonymity and Accountability for Next Generation Internet

Mallios, Yannis; Modi, Sudeep; Agarwala, Aditya; Johns, Christina

Individual privacy has become a major concern, due to the intrusive nature of the services and websites that collect increasing amounts of private information. One of the notions that can lead towards privacy protection is that of anonymity. Unfortunately, anonymity can also be maliciously exploited by attackers to hide their actions and identity. Thus some sort of accountability is also required. The current Internet has failed to provide both properties, as anonymity techniques are difficult to fully deploy and thus are easily attacked, while the Internet provides limited level of accountability. The Next Generation Internet (NGI) provides us with the opportunity to examine how these conflicting properties could be efficiently applied and thus protect users’ privacy while holding malicious users accountable. In this paper we present the design of a scheme, called Persona that can provide anonymity and accountability in the network layer of NGI. More specifically, our design requirements are to combine these two conflicting desires in a stateless manner within routers. Persona allows users to choose different levels of anonymity, while it allows the discovery of malicious nodes.

Knowledge, attitudes, beliefs, and behaviors of the business community relative to HIV-AIDS.

One of the goals of the Centers for Disease Control's (CDC) policy on the prevention of human immunodeficiency virus (HIV) infection and acquired immunodeficiency syndrome (AIDS) is to support business organizations in implementing HIV and AIDS information, education, and prevention activities. However, the response of the American business community to HIV infection and AIDS has been varied. Although company executives consider AIDS to be one of the leading problems in the country, surveys typically indicate that less than one-third of businesses have or are developing some type of AIDS policy. The workplace appears to be a valid site for AIDS information and education programs, given the weight employees attach to information received there. However, workplace education and information programs are undertaken primarily by large companies. Many small companies do not devote much time and effort to these activities, even though extensive, indepth educational programs are likely to have positive impacts on worker attitudes and behavior, whereas short programs or literature distribution may only increase workers' fears. The question of what is an effective workplace program still needs additional research. Very little is known about the magnitude of the costs of HIV infection and AIDS to business. These costs, which are affected by the changing roles of employer-based health insurance, cost shifting, and public programs, will influence how employers react to the epidemic and how they respond to CDC's prevention initiatives.

The HIV surveillance system in Germany is based on mandatory, anonymous notification of newly diagnosed HIV cases by laboratories. Because the time between HIV infection and the diagnosis of HIV varies widely between persons, it is difficult to determine the number of cases of recent HIV infection among newly diagnosed cases of HIV. In Germany, the BED-capture-enzyme immunoassay (BED-CEIA) has been used to distinguish between recent and long-standing HIV infection. The aim of this analysis is to report the proportion of cases of recent HIV infection among newly diagnosed cases in Germany between 2008 and 2014 and to identify factors associated with recent infections. A sample of voluntary laboratories among all HIV diagnostic laboratories was recruited. Residual blood from HIV diagnostic tests was spotted on filter paper as dried serum or dried plasma spots and was sent along with the notification form of the HIV cases. The BED-CEIA test was performed. A case was defined as recent HIV infection with a BED-CEIA test result of less than 0.8 normalized optical density, with the exclusion of CDC stage C. The proportion of recent newly diagnosed HIV infections among different groups (such as transmission groups, gender or age groups) was calculated. We used logistic regression to identify factors associated with recent HIV infection and to identify subpopulations with high proportions of recent HIV infections. Approximately 10,257 newly diagnosed cases were tested for recency using the BED-CEIA. In total, 3084 (30.4%) of those were recently infected with HIV. The highest proportion of recent HIV infections was found among men who had sex with men (MSM) (35%) and persons between 18 and 25 years of age (43.0%). Logistic regression revealed that female German intravenous drug users with a recent HIV infection had a higher chance of being detected than German MSM (OR 2.27). Surveillance of recent HIV infection is a useful additional tool to monitor the HIV epidemic in

Academic freedom, public reactions, and anonymity.

PubMed

Häyry, Matti

2014-05-01

Academic freedom can be defined as immunity against adverse reactions from the general public, designed to keep scholars unintimidated and productive even after they have published controversial ideas. Francesca Minerva claims that this notion of strict instrumental academic freedom is supported by Ronald Dworkin, and that anonymity would effectively defend the sphere of immunity implied by it. Against this, I argue that the idea defended by Minerva finds no support in the work by Dworkin referred to; that anonymity would not in most cases effectively protect the kind of immunity sought after; and that in some cases it would not even be desirable to protect scholars from public reactions to their controversial claims. © 2014 John Wiley & Sons Ltd.

To examine HIV risks among South African men who report having been sexually assaultive. Men (N = 412) in Cape Town completed anonymous surveys. Twenty-three percent reported a history of sexual assault. Men who had been sexually assaultive were younger, reported more sex partners, were more likely to have a history of genital ulcers, and more likely to have exchanged money for sex. Sexually assaultive men were also more likely to endorse rape myths. Interventions that target men as the agents of change in reducing sexual assaults and HIV transmission are urgently needed.

2015-01-01

Background Unprotected anal intercourse (UAI) is a major pathway towards secondary HIV transmission among men who have sex with men (MSM). We explored the socio-cultural environment and individual beliefs and experiences conducive to UAI in the context of Southern China. Methods We employed an ethnographic approach utilizing a socio-ecological framework to conduct repeated in-depth interviews with thirty one newly diagnosed HIV positive MSM as well as participant observations in Shenzhen based healthcare settings, MSM venues and NGO offices. Results Some men (6/31) reported continuing to practice UAI after an initial diagnosis of being HIV positive. For MSM who had existing lovers or stable partners, the fear of losing partners in a context of non-serostatus disclosure was testified to be a major concern. MSM with casual partners reported that anonymous sexual encounters and moral judgments played a significant role in their sexual risk behaviors. Simultaneously, self-reported negative emotional and psychological status, perception and idiosyncratic risk interpretation, as well as substance abuse informed the intrapersonal context for UAI. Conclusion UAI among these HIV positive MSM was embedded in an intrapersonal context, related to partner type, shaped by anonymous sexual encounters, psychological status, and moral judgments. It is important that prevention and intervention for secondary HIV transmission among newly diagnosed HIV positive MSM in China take into account these contextual factors. PMID:26461258

Young girls in sub Saharan Africa are reported to have higher rates of human immunodeficiency virus (HIV) infection compared to boys in the same age group. Knowledge of HIV status amongst high schools learners provides an important gateway to prevention and treatment services. This study aimed at determining the HIV prevalence and explored the feasibility of HIV testing among high school learners. Between September 2010 and February 2011, a linked, anonymous cross-sectional survey was conducted in two public sector high schools in the rural KwaZulu-Natal midlands. Following written informed consent, dried blood spot samples (DBS) were collected and tested for HIV. The overall and age-specific HIV prevalence were compared with select demographic variables. The HIV prevalence in learners aged 12 to 25 in school A was 4.7% (95% CI 2.8-6.5) compared to 2.5% (95% CI 1.6-3.5) in school B, (p=0.04). Whilst the HIV prevalence was similar for boys at 1.3% (95% CI 0-2.8) in school A and 1.7% (95% CI 0.5-2.8) in school B, the prevalence in girls was consistently higher and was 7.7% (95% CI 4.5-10.9) in school A and 3.2% (95% CI 1.8-4.6) in school B. The age-specific HIV prevalence in girls increased 1.5 to 2 fold for each two year age category, while for boys the prevalence was stable across all age groups. The high HIV prevalence in female learners underscores the importance of sexual reproductive health and schools-based HIV testing programs as an important gateway to prevention and treatment services.

Zhang, Jia; Duan, Haixin; Liu, Wu; Wu, Jianping

Compared with traditional static anonymous communication networks, the P2P architecture can provide higher anonymity in communication. However, the P2P architecture also leads to more challenges, such as route, stability, trust and so on. In this paper, we present WindTalker, a P2P-based low-latency anonymous communication network. It is a pure decentralized mix network and can provide low-latency services which help users hide their real identity in communication. In order to ensure stability and reliability, WindTalker imports “seed nodes” to help a peer join in the P2P network and the peer nodes can use gossip-based protocol to exchange active information. Moreover, WindTalker uses layer encryption to ensure the information of relayed messages cannot be leaked. In addition, malicious nodes in the network are the major threat to anonymity of P2P anonymous communication, so WindTalker imports a trust mechanism which can help the P2P network exclude malicious nodes and optimize the strategy of peer discovery, tunnel construction, and relaying etc. in anonymous communications. We deploy peer nodes of WindTalker in our campus network to test reliability and analyze anonymity in theory. The network measurement and simulation analysis shows that WindTalker can provide low-latency and reliable anonymous communication services.

New York governor signs bill to track HIV cases by name.

PubMed

1998-07-24

Senate Bill 4422-B, a partner notification bill that uses name-based reporting to track HIV cases, was signed by New York Governor George Pataki on July 7, 1998. The new legislation requires physicians to report the names of all HIV-positive patients to the State Department of Health so that public officials can notify spouses, sexual partners, and needle-sharing partners of possible exposure. This information will become part of a State-wide case surveillance system. Patient advocacy and civil liberties groups did not support the bill, stating that it would erode the physician-patient relationship by breaching confidentiality. The new legislation does not apply to anonymous testing sites, although once individuals begin HIV-related medical treatment, their name will be sent to the State.

An ever growing for application of electronic health records (EHRs) has improved healthcare providers' communications, access to data for secondary use and promoted the quality of services. Patient's privacy has been changed to a great issue today since there are large loads of critical information in EHRs. Therefore, many privacy preservation techniques have been proposed and anonymization is a common one. This study aimed to investigate the effectiveness of anonymization in preserving patients' privacy. The articles published in the 2005-2016 were included. Pubmed, Cochrane, IEEE and ScienceDirect were searched with a variety of related keywords. Finally, 18 articles were included. In the present study, the relevant anonymization issues were investigated in four categories: secondary use of anonymized data, re-identification risk, anonymization effect on information extraction and inadequacy of current methods for different document types. The results revealed that though anonymization cannot reduce the risk of re-identification to zero, if implemented correctly, can manage to help preserve patient's privacy.

We examined whether orphaned and fostered children and children of HIV-infected parents are disadvantaged in schooling, nutrition, and health care. We analyzed data on 2,756 children aged 0-4 years and 4,172 children aged 6-14 years included in the 2003 Kenya Demographic and Health Survey, with linked anonymous HIV testing, using multivariate logistic regression. Results indicate that orphans, fostered children, and children of HIV-infected parents are significantly less likely to attend school than non-orphaned/non-fostered children of HIV-negative parents. Children of HIV-infected parents are more likely to be underweight and wasted, and less likely to receive medical care for ARI and diarrhea. Children of HIV-negative single mothers are also disadvantaged on most indicators. The findings highlight the need to expand child welfare programs to include not only orphans but also fostered children, children of single mothers, and children of HIV-infected parents, who tend to be equally, if not more, disadvantaged.

We make use of the voluntary HIV and syphilis test results conducted at five gay saunas in Taipei from August of 1999 to end of 2002 to estimate the number of HIV-positive gay saunas patrons in Taipei area by utilizing Hierarchical Bayes method in Generalized Removal Model for Open Populations (GERMO). Considering the effect of a nearby anonymous HIV quick test program on the gay sauna HIV serotesting data, we make use of the association between HIV and syphilis serotesting results from the gay sauna program to amend possible measurement error occurred at the time of data collection by utilizing the regression calibration method. The median estimates for the number of HIV-positive patrons of the five gay saunas increase from 120 (95% CI: 76.5-159.0) during the first half of 2000 to 224 (95% CI: 171.0-265.5) for the second half of 2002. The result, indicating two-fold increase within two and half years, confirms that the gay sauna patrons in Taipei area are at high risk for HIV infection.

During a three-month period in 1989, 820 pregnant women attending the antenatal clinic of the Aarhus University Hospital, Denmark, were offered a HIV-antibody test and asked to fill out an anonymous questionnaire about attitudes to HIV-antibody testing; 779 (95.0%) agreed to do so. One hundred and fifty-six women (20.0% of the participants) had been tested on a previous occasion, and 629 (80.7%) accepted the present offer to be tested. The most prevalent reasons to decline testing were indifference to the epidemic (45.3% of those declining), refusal of (further) blood testing (34.7%) and fear of being infected (16.7%). Women who consented to be tested most often expressed fear of being infected (21.8%). Fear of registration worried less than 5% of study group members; only 1% declined to be tested because of such worry. The pattern of worries expressed by the pregnant women is interpreted as one of anxiety and, in part at least, perplexity as concerns how to take rational consequences of public messages about the HIV epidemic. It is suggested that future surveillance be based primarily on voluntary testing and, whenever needed and possible, supplied with anonymous unlinked testing of existing blood samples from groups and persons declining to be tested. Such surveillance strategies should be supported in individual patient contacts and public health educational campaigns underscoring the risk of heterosexual transmission of HIV and the need for repeated HIV-antibody testing of selected groups and individuals.

Culture or anonymity? Differences in proposer behaviour in Korea and Germany.

Horak, Sven

2015-10-01

This study explores the proposer behaviour in an ultimatum game (UG) frame under anonymous and non-anonymous conditions among a Korean and German subject pool (n = 590) in comparison. Whereas the anonymous condition is represented by the standard UG, the non-anonymous condition integrates an aggregate of the Korean cultural context variables university affiliation, regional origin and seniority. The latter, a classic Confucian context variable, is measured by age differentials. The former two are impactful components of so-called Yongo networks, a unique Korean informal institution identical to Chinese Guanxi ties. Yongo networks, yet underrepresented in research, are said to be a central context variable to explain Korean social ties and decision-making behaviour. We observe significant differences between the offer behaviours of Korean and German subjects when exposing selected cultural variables. We argue that the behavioural differences observed are in fact due to culture not anonymity. © 2015 International Union of Psychological Science.

Sperm donor anonymity and compensation: an experiment with American sperm donors

Abstract Most sperm donation that occurs in the USA proceeds through anonymous donation. While some clinics make the identity of the sperm donor available to a donor-conceived child at age 18 as part of ‘open identification’ or ‘identity release programs,’ no US law requires clinics to do so, and the majority of individuals do not use these programs. By contrast, in many parts of the world, there have been significant legislative initiatives requiring that sperm donor identities be made available to children after a certain age (typically when the child turns 18). One major concern with prohibiting anonymous sperm donation has been that the number of willing sperm donors will decrease leading to shortages, as have been experienced in some of the countries that have prohibited sperm donor anonymity. One possible solution, suggested by prior work, would be to pay current anonymous sperm donors more per donation to continue to donate when their anonymity is removed. Using a unique sample of current anonymous and open identity sperm donors from a large sperm bank in the USA, we test that approach. As far as we know, this is the first attempt to examine what would happen if the USA adopted a prohibition on anonymous sperm donation that used the most ecologically valid population, current sperm donors. We find that 29% of current anonymous sperm donors in the sample would refuse to donate if the law changed such that they were required to put their names in a registry available to donor-conceived children at age 18. When we look at the remaining sperm donors who would be willing to participate, we find that they would demand an additional $60 per donation (using our preferred specification). We also discuss the ramifications for the industry. PMID:28852536

Tuberculosis (TB) and HIV comorbidity is a major challenge in TB prevention and control but difficult to assess in Germany as in other countries, where data confidentiality precludes notifying the HIV status of TB patients. We aimed to estimate the HIV-prevalence in TB patients in Germany, 2002–2009, and to characterize the HIV/TB patients demographically. Data from the long-term observational open multicentre cohort ClinSurv HIV were used to identify incident TB in HIV-positive individuals. We assessed the cohort’s coverage for the nationwide HIV-positive population by contrasting ClinSurv HIV patients under antiretroviral therapy (ART) with national HIV patient numbers derived from ART prescriptions (data by Insight Health; available for 2006–2009). The HIV-prevalence in TB patients was calculated as the number of HIV/TB cases projected for Germany over all culture-positive TB notifications. From 2002 to 2009, 298 of 15,531 HIV-positive patients enrolled in the ClinSurv HIV cohort were diagnosed with TB. A 21% cohort coverage was determined. The annual estimates of the HIV-prevalence in TB patients were on average 4.5% and ranged from 3.5% (95%CI 2.3–5.1%) in 2007 to 6.6% (95%CI 5.0–8.5%) in 2005. The most recent estimate for 2009 was 4.0% (95%CI 2.6–5.9%). The 298 HIV/TB patients were characterized by a male-to-female ratio of 2.1, by a median age of 38 years at TB diagnosis, and by 59% of the patients having a foreign origin, mainly from Subsahara Africa. We provide, to our knowledge, the first estimate of the HIV-prevalence in TB patients for Germany by joint evaluation of anonymous HIV and TB surveillance data sources. The identified level of HIV in TB patients approximates available surveillance data from neighbouring countries and indicates a non-negligible HIV/TB burden in Germany. Our estimation approach is valuable for epidemiological monitoring of HIV/TB within the current legal frameworks. PMID:23145087

Health information technologies facilitate the collection of massive quantities of patient-level data. A growing body of research demonstrates that such information can support novel, large-scale biomedical investigations at a fraction of the cost of traditional prospective studies. While healthcare organizations are being encouraged to share these data in a de-identified form, there is hesitation over concerns that it will allow corresponding patients to be re-identified. Currently proposed technologies to anonymize clinical data may make unrealistic assumptions with respect to the capabilities of a recipient to ascertain a patients identity. We show that more pragmatic assumptions enable the design of anonymization algorithms that permit the dissemination of detailed clinical profiles with provable guarantees of protection. We demonstrate this strategy with a dataset of over one million medical records and show that 192 genotype-phenotype associations can be discovered with fidelity equivalent to non-anonymized clinical data.

Should Mitochondrial Donation Be Anonymous?

Appleby, John B

2018-01-01

Abstract Currently in the United Kingdom, anyone donating gametes has the status of an open-identity donor. This means that, at the age of 18, persons conceived with gametes donated since April 1, 2005 have a right to access certain pieces of identifying information about their donor. However, in early 2015, the UK Parliament approved new regulations that make mitochondrial donors anonymous. Both mitochondrial donation and gamete donation are similar in the basic sense that they involve the contribution of gamete materials to create future persons. Given this similarity, this paper presumes that both types of donor should be treated the same and made open-identity under the law, unless there is a convincing argument for treating them differently. I argue that none of the existing arguments that have been made so far in favor of mitochondrial donor anonymity are convincing and mitochondrial donors should therefore be treated as open-identity donors under UK law.

In health sector, trust is considered important because it indirectly influences the quality of health care through patient satisfaction, adherence and the continuity of its relationship with health care professionals and the promotion of accurate and timely diagnoses. One of the important requirements of TRSs in the health sector is rating secrecy, which mandates that the identification information about the service consumer should be kept secret to prevent any privacy violation. Anonymity and trust are two imperative objectives, and no significant explicit efforts have been made to achieve both of them at the same time. In this paper, we present a framework for solving the problem of reconciling trust with anonymity in the health sector. Our solution comprises Anonymous Reputation Management (ARM) protocol and Context-aware Trustworthiness Assessment (CTA) protocol. ARM protocol ensures that only those service consumers who received a service from a specific service provider provide a recommendation score anonymously with in the specified time limit. The CTA protocol computes the reputation of a user as a service provider and as a recommender. To determine the correctness of the proposed ARM protocol, formal modelling and verification are performed using High Level Petri Nets (HLPN) and Z3 Solver. Our simulation results verify the accuracy of the proposed context-aware trust assessment scheme. PMID:29649267

Anonymized reflection was employed as an innovative way of teaching ethics in order to enhance students' ability in ethical decision making during a Care of the Dying Patient and Family' module. Both qualitative and quantitative data were collected from the first two student cohorts who experienced anonymized reflection ( n = 24). The themes identified were the richness and relevance of scenarios, small-group work and a team approach to teaching. Students indicated that they preferred this style of teaching. This finding was verified by a postal questionnaire conducted four months later. The conclusions drawn from this study suggest that using anonymized reflection is an effective method for teaching ethics to nurses and indicates that learning about ethical issues in this way reduces uncertainties.

As ART programmes in African settings expand beyond the pilot stages, adherence to treatment may become an increasing challenge. This qualitative study examines potential barriers to, and facilitators of, adherence to ART in a workplace programme in South Africa. We conducted key informant interviews with 12 participants: six ART patients, five health service providers (HSPs) and one human resources manager. The main reported barriers were denial of existence of HIV or of one's own positive status, use of traditional medicines, speaking a different language from the HSP, alcohol use, being away from home, perceived severity of side-effects, feeling better on treatment and long waiting times at the clinic. The key facilitators were social support, belief in the value of treatment, belief in the importance of one's own life to the survival of one's family, and the ability to fit ART into daily life schedules. Given the reported uncertainty about the existence of HIV disease and the use of traditional medicines while on ART, despite a programme emphasising ART counselling, there is a need to find effective ways to support adherence to ART even if the individual does not accept biomedical concepts of HIV disease or decides to use traditional medicines. Additionally, providers should identify ways to minimize barriers in communication with patients with whom they have no common language. Finally, dissatisfaction with clinical services, due to long waiting times, should be addressed.

HIV prevalence among high school learners - opportunities for schools-based HIV testing programmes and sexual reproductive health services

PubMed Central

2012-01-01

Background Young girls in sub Saharan Africa are reported to have higher rates of human immunodeficiency virus (HIV) infection compared to boys in the same age group. Knowledge of HIV status amongst high schools learners provides an important gateway to prevention and treatment services. This study aimed at determining the HIV prevalence and explored the feasibility of HIV testing among high school learners. Methods Between September 2010 and February 2011, a linked, anonymous cross-sectional survey was conducted in two public sector high schools in the rural KwaZulu-Natal midlands. Following written informed consent, dried blood spot samples (DBS) were collected and tested for HIV. The overall and age-specific HIV prevalence were compared with select demographic variables. Results The HIV prevalence in learners aged 12 to 25 in school A was 4.7% (95% CI 2.8-6.5) compared to 2.5% (95% CI 1.6-3.5) in school B, (p = 0.04). Whilst the HIV prevalence was similar for boys at 1.3% (95% CI 0-2.8) in school A and 1.7% (95% CI 0.5-2.8) in school B, the prevalence in girls was consistently higher and was 7.7% (95% CI 4.5-10.9) in school A and 3.2% (95% CI 1.8-4.6) in school B. The age-specific HIV prevalence in girls increased 1.5 to 2 fold for each two year age category, while for boys the prevalence was stable across all age groups. Conclusions The high HIV prevalence in female learners underscores the importance of sexual reproductive health and schools-based HIV testing programs as an important gateway to prevention and treatment services.

2017-12-05

Since the late 1980s, human immunodeficiency virus (HIV) sentinel serosurveillance among pregnant women attending select antenatal clinics (ANCs) based on unlinked anonymous testing (UAT) has provided invaluable information for tracking HIV prevalence and trends and informing global and national HIV models in most countries with generalized HIV epidemics. However, increased coverage of HIV testing, prevention of mother-to-child transmission (PMTCT), and antiretroviral therapy has heightened ethical concerns about UAT. PMTCT programs now routinely collect demographic and HIV testing information from the same pregnant women as serosurveillance and therefore present an alternative to UAT-based ANC serosurveillance. This paper reports on the evolution and current direction of the global approach to HIV surveillance among pregnant women attending ANCs, including the transition away from traditional UAT-based serosurveillance and toward new guidance from the World Health Organization and the Joint United Nations Programme on HIV/AIDS on the implementation of surveillance among pregnant women attending ANCs based on routine PMTCT program data. ©Jacob Dee, Jesus M Garcia Calleja, Kimberly Marsh, Irum Zaidi, Christopher Murrill, Mahesh Swaminathan.

Background Female sex workers (FSWs) play an important role in transmitting HIV and syphilis from high-risk groups to the general population. However, the trends in HIV and syphilis epidemics in Chinese FSWs in the period after 2000 are unclear to date. Methods The Preferred Reporting Items for Systematic Reviews and Meta-Analyses Statement was followed. Seven databases were searched for published peer-reviewed articles. The incidence of HIV and syphilis in FSWs in different time periods, provinces and workplaces in China were separately pooled by meta-analysis. Correlation analysis was conducted between HIV and syphilis incidence and study time, respectively. Results After 1,662 articles were screened, 190 published papers were included in the final analysis. Estimated HIV prevalence was 0.284% (95% CI: 0.080–0.488%) in the period 2000–2002, 0.211% (95% CI: 0.149–0.273%) in 2003–2005, 0.242% (95% CI: 0.190–0.294%) in 2006–2008 and 0.041% (95% CI: 0.024–0.058%) in 2009–2011. The corresponding syphilis prevalence was 9.669% (95% CI: 7.810–11.529%), 4.970% (95% CI: 4.384–5.556%), 4.404% (95% CI: 4.032–4.775%) and 3.169% (95% CI: 2.738–3.600%), respectively. Spearman rank correlation coefficients were −0.165 (p = 0.002) between HIV prevalence and study time, and −0.209 (p = 0.000) between syphilis prevalence and study time. The combined HIV prevalence was 0.318% (95% CI: 0.156–0.479%) in medium and high-tier workplaces and 0.393% (95% CI: 0.176–0.610%) in low-tier workplaces. The corresponding syphilis prevalence was 3.216% (95% CI: 2.192–4.240%) and 13.817% (95% CI: 10.589–17.044%), respectively. Conclusions Our data suggested a decline in HIV and syphilis epidemics in FSWs in China on a national level during the study period (2000–2011). FSWs in low-tier workplaces should be given more attention in the future to ensure they are included in prevention programs for HIV and sexually transmitted diseases. PMID:24349288

Anonymous pastoral care is one of the options for help in problems pertaining to sexuality. This paper explores the topics they seek help for, the religious aspects involved, and the relation between the normativity of their church tradition on the one hand and sexual and spiritual health criteria on the other. We analyzed helpseeking questions of two protestant Christian organizations in the Netherlands providing anonymous pastoral care: Refoweb and EO-Nazorg. Sexual themes were addressed in 19 and 2.3 % of the submitted questions, respectively. Of the helpseekers, 56 % is female, 15 % male, and 29 % unknown. Questions and problems for which people seek anonymous pastoral care focus primarily on premarital abstinence, gender roles, contraception, sexual orientation and masturbation. The authority of the Bible seems to be important for questioners, especially when dealing with ethical questions. Different relations between the normativity of the church tradition and sexual and spiritual health are discussed.

Violence against health care workers perpetrated by clients and/or their friends and family (Type II) is a growing problem that can severely impact health care delivery. We examined the prevalence of Type II workplace violence among nurses and midwives in sub-Saharan Africa and its association with work status, schedule, and client characteristics. Nurses and midwives (n = 712) completed an anonymous survey while attending nursing meetings. Generalized estimating equation models, accounting for clustering within residing countries, were employed. Participants who were exposed to risky client characteristics (aOR = 1.39-1.78, p < .001), and those who worked more than 40 hours a week were more likely to have experienced Type II workplace violence (aOR = 1.72-2.15, p < .05). Findings will inform policy and organization level interventions needed to minimize nurses' and midwives' exposure to Type II workplace violence by identifying risky clients and addressing long work hours.

Occupational contact dermatitis (OCD) is a common occupational disease. Evidence suggests that education and training are effective prevention strategies. In spite of these known prevention strategies, workers continue to develop OCD. Little is reported regarding the actual training experience of workers. To examine the training experience of workers with contact dermatitis to identify areas for improvement. Participants were workers being assessed for contact dermatitis in an occupational health clinic. The anonymous survey collected demographics, workplace characteristics, and education and prevention practices. Approximately 80% reported general occupational health and safety training; however, only 49% reported skin-specific training (SST). For workers reporting SST, most received information regarding exposure avoidance, hand washing, and glove use. This content was reported as helpful by at least 50%. Workers who did not receive SST indicated the most important content would be warning signs of skin problems, how to avoid exposure and skin care while using gloves. While the study was anonymous and used self-reported of training experience, the study suggests there are gaps in skin protection training. Addressing these gaps may lead to improved prevention and reduction in OCD. © The Author(s) 2017. Published by Oxford University Press on behalf of the British Occupational Hygiene Society.

Effects of Data Anonymization by Cell Suppression on Descriptive Statistics and Predictive Modeling Performance

2002-01-01

Protecting individual data in disclosed databases is essential. Data anonymization strategies can produce table ambiguation by suppression of selected cells. Using table ambiguation, different degrees of anonymization can be achieved, depending on the number of individuals that a particular case must become indistinguishable from. This number defines the level of anonymization. Anonymization by cell suppression does not necessarily prevent inferences from being made from the disclosed data. Preventing inferences may be important to preserve confidentiality. We show that anonymized data sets can preserve descriptive characteristics of the data, but might also be used for making inferences on particular individuals, which is a feature that may not be desirable. The degradation of predictive performance is directly proportional to the degree of anonymity. As an example, we report the effect of anonymization on the predictive performance of a model constructed to estimate the probability of disease given clinical findings.

Obtaining employment is an important part of recovery for many people living with HIV/AIDS (PLHA). However, this population often faces barriers in their attempt to reenter the workplace. One potential barrier lies in the decision-making of employers. Little is known about what influences employers' decision to hire PLHA. The current paper addresses this gap with findings from 156 quantitative interviews with employers across Chicago, Beijing, and Hong Kong regarding the hiring of people with HIV/AIDS. Hierarchical regression analysis showed that both fear of contagion and perceived incompetence are important factors in employers' decision to interview even after controlling for variables related to the employers' business size, their education level, and the provision of health benefits. These two variables accounted for 42% of the variance in employers' decision to interview. Implications of these findings are considered for better understanding of HIV-related employment stigma and further intervention for employing PLHA.

A New Heuristic Anonymization Technique for Privacy Preserved Datasets Publication on Cloud Computing

Recent advancement in Information and Communication Technologies (ICT) demanded much of cloud services to sharing users’ private data. Data from various organizations are the vital information source for analysis and research. Generally, this sensitive or private data information involves medical, census, voter registration, social network, and customer services. Primary concern of cloud service providers in data publishing is to hide the sensitive information of individuals. One of the cloud services that fulfill the confidentiality concerns is Privacy Preserving Data Mining (PPDM). The PPDM service in Cloud Computing (CC) enables data publishing with minimized distortion and absolute privacy. In this method, datasets are anonymized via generalization to accomplish the privacy requirements. However, the well-known privacy preserving data mining technique called K-anonymity suffers from several limitations. To surmount those shortcomings, I propose a new heuristic anonymization framework for preserving the privacy of sensitive datasets when publishing on cloud. The advantages of K-anonymity, L-diversity and (α, k)-anonymity methods for efficient information utilization and privacy protection are emphasized. Experimental results revealed the superiority and outperformance of the developed technique than K-anonymity, L-diversity, and (α, k)-anonymity measure.

In urban China, more single women are becoming pregnant and resorting to induced abortion, despite the wide availability of temporary methods of contraception. We developed and piloted a workplace-based intervention to promote contraceptive use in unmarried female migrants working in privately owned factories. Quasi-experimental design. In consultation with clients, we developed a workplace based intervention to promote contraception use in unmarried female migrants in a privately owned factory. We then implemented this in one factory, using a controlled before-and-after design. The intervention included lectures, bespoke information leaflets, and support to the factory doctors in providing a contraceptive service. 598 women participated: most were under 25, migrants to the city, with high school education. Twenty percent were lost when staff were made redundant, and implementation was logistically complicated. All women attended the initial lecture, and just over half the second lecture. Most reported reading the educational material provided (73%), but very few women reported using the free family planning services offered at the factory clinic (5%) or the Family Planning Institute (3%). At baseline, 90% (N = 539) stated that contraceptives were required if having sex before marriage; of those reporting sex in the last three months, the majority reporting using contraceptives (78%, 62/79) but condom use was low (44%, 35/79). Qualitative data showed that the reading material seemed to be popular and young women expressed a need for more specific reproductive health information, particularly on HIV/AIDS. Women wanted services with some privacy and anonymity, and views on the factory service were mixed. Implementing a complex intervention with a hard to reach population through a factory in China, using a quasi-experimental design, is not easy. Further research should focus on the specific needs and service preferences of this population and these should be

Objectives. We studied the HIV risk behaviors of patrons of the 3 commercial sex venues for men in Seattle, Washington. Methods. We conducted cross-sectional, observational surveys in 2004 and 2006 by use of time–venue cluster sampling with probability proportional to size. Surveys were anonymous and self-reported. We analyzed the 2004 data to identify patron characteristics and predictors of risk behaviors and compared the 2 survey populations. Results. Fourteen percent of respondents reported a previous HIV-positive test, 14% reported unprotected anal intercourse, and 9% reported unprotected anal intercourse with a partner of unknown or discordant HIV status during the current commercial sex venue visit. By logistic regression, recent unprotected anal intercourse outside of a commercial sex venue was independently associated with unprotected anal intercourse. Sex venue site and patron drug use were strongly associated with unprotected anal intercourse at the crude level. The 2004 and 2006 survey populations did not differ significantly in demographics or behaviors. Conclusions. Patron and venue-specific characteristics factors may each influence the frequency of HIV risk behaviors in commercial sex venues. Future research should evaluate the effect of structural and individual-level interventions on HIV transmission. PMID:19218174

To facilitate long-term safety surveillance of marketing drugs, many spontaneously reporting systems (SRSs) of ADR events have been established world-wide. Since the data collected by SRSs contain sensitive personal health information that should be protected to prevent the identification of individuals, it procures the issue of privacy preserving data publishing (PPDP), that is, how to sanitize (anonymize) raw data before publishing. Although much work has been done on PPDP, very few studies have focused on protecting privacy of SRS data and none of the anonymization methods is favorable for SRS datasets, due to which contain some characteristics such as rare events, multiple individual records, and multi-valued sensitive attributes. We propose a new privacy model called MS(k, θ (*) )-bounding for protecting published spontaneous ADE reporting data from privacy attacks. Our model has the flexibility of varying privacy thresholds, i.e., θ (*) , for different sensitive values and takes the characteristics of SRS data into consideration. We also propose an anonymization algorithm for sanitizing the raw data to meet the requirements specified through the proposed model. Our algorithm adopts a greedy-based clustering strategy to group the records into clusters, conforming to an innovative anonymization metric aiming to minimize the privacy risk as well as maintain the data utility for ADR detection. Empirical study was conducted using FAERS dataset from 2004Q1 to 2011Q4. We compared our model with four prevailing methods, including k-anonymity, (X, Y)-anonymity, Multi-sensitive l-diversity, and (α, k)-anonymity, evaluated via two measures, Danger Ratio (DR) and Information Loss (IL), and considered three different scenarios of threshold setting for θ (*) , including uniform setting, level-wise setting and frequency-based setting. We also conducted experiments to inspect the impact of anonymized data on the strengths of discovered ADR signals. With all three

South Africa is in the midst of a devastating HIV-AIDS epidemic and most new HIV infections occur among young adults and adolescents. The current study examined risk behaviors and HIV risk factors among young people living in a Black South African township. Using community-based outreach methods of street intercept and facility-based surveying, 113 men and 115 women age 25 and younger responded to an anonymous survey. Results showed that men (68%) and women (56%) reported HIV-related high risk sexual behaviors. Although knowledge about HIV transmission was generally high, there was evidence that misconceptions about AIDS persist, particularly myths related to HIV transmission. For young men, HIV risk factors were associated with fewer years of education, lower levels of AIDS-related knowledge, condom attitudes, and Dagga (marijuana) use. Among young women, HIV risk factors were associated with beliefs that condoms get in the way of sex and rates of unprotected vaginal intercourse. Despite adequate general AIDS knowledge and risk sensitization, South African youth demonstrated high rates of sexual practices that place them at risk for HIV infection. There is an urgent need for behavioral interventions targeted to young South Africans living in the most economically disadvantaged areas.

Community engagement research is widely discussed but rarely implemented. This article describes the implementation of a community engagement research project on Dual Diagnosis Anonymous, a rapidly spreading peer support program in Oregon for people with co-occurring mental illness and substance use disorders. After three years of discussions, overcoming barriers, and involving several institutions, this grassroots research project has been implemented and is expanding. Active participants in Dual Diagnosis Anonymous inspired and instructed policy makers, professionals, and students. Community engagement research requires frontline participants, community members, and professional collaborators to overcome multiple barriers with persistence and steadfastness. Building trust, collaboration, and structures for community engagement research takes time and a community effort.

Health outcomes and self-labeling as a victim of workplace bullying.

Vie, Tina Løkke; Glasø, Lars; Einarsen, Ståle

2011-01-01

This study investigated the extent to which self-labeling as a victim of workplace bullying mediates or moderates the relationship between exposure to bullying and the target's health outcomes. Data were collected by means of anonymous self-report questionnaires. A total of 1024 employees in a transport organization participated in the study, among whom 116 self-labeled victims were identified. Exposure to bullying was measured by a short version of the Negative Acts Questionnaire, while the respondents' health outcomes were measured by the Bergen Health Checklist. The findings showed that self-labeling both moderated and partially mediated the relationship between exposure to bullying and the targets' health. However, the moderator analyses indicate that self-labeling only acts as moderator in cases of low exposure. Intense exposure to bullying behaviors is related to increased levels of health complaints regardless of the target's subjective appraisal of being a victim or not. Self-labeling as a victim plays an important role in the victimizing process, although persistent exposure to workplace bullying seems to have considerable harmful effects on the target's health independently of whether the experience is labeled as bullying or not.

Size matters: How population size influences genotype–phenotype association studies in anonymized data

Objective Electronic medical records (EMRs) data is increasingly incorporated into genome-phenome association studies. Investigators hope to share data, but there are concerns it may be “re-identified” through the exploitation of various features, such as combinations of standardized clinical codes. Formal anonymization algorithms (e.g., k-anonymization) can prevent such violations, but prior studies suggest that the size of the population available for anonymization may influence the utility of the resulting data. We systematically investigate this issue using a large-scale biorepository and EMR system through which we evaluate the ability of researchers to learn from anonymized data for genome- phenome association studies under various conditions. Methods We use a k-anonymization strategy to simulate a data protection process (on data sets containing clinical codes) for resources of similar size to those found at nine academic medical institutions within the United States. Following the protection process, we replicate an existing genome-phenome association study and compare the discoveries using the protected data and the original data through the correlation (r2) of the p-values of association significance. Results Our investigation shows that anonymizing an entire dataset with respect to the population from which it is derived yields significantly more utility than small study-specific datasets anonymized unto themselves. When evaluated using the correlation of genome-phenome association strengths on anonymized data versus original data, all nine simulated sites, results from largest-scale anonymizations (population ∼ 100;000) retained better utility to those on smaller sizes (population ∼ 6000—75;000). We observed a general trend of increasing r2 for larger data set sizes: r2 = 0.9481 for small-sized datasets, r2 = 0.9493 for moderately-sized datasets, r2 = 0.9934 for large-sized datasets. Conclusions This research implies that regardless of the

Abstract This study had three objectives: (1) to investigate the impact of workplace incivility on job burn-out of new nursing staff, (2) to verify the partial mediating role of anxiety in the relationship between workplace incivility and job burn-out, (3) to examine the resilience moderating the relations between workplace incivility and job burn-out. Design A cross-sectional online survey was conducted in May 2016 in China. Setting The survey was conducted in 54 cities across 29 provinces of China. Participants A total of 903 participants were invited. Ultimately, 696 new nurses (<3 service years) completed valid questionnaires. The effective response rate was 77.1%. Entry criteria: voluntary participation, having less than three service years and being a registered nurse. Exclusion criteria: being an irregular nurse, having more than three service years and refusing to participate in this work. Outcome measures An anonymous questionnaire was distributed among new nurses. The relationships and mechanism among the variables were explored using descriptive statistical analysis, Pearson’s correlation coefficient and multiple linear regression analysis. Results The findings showed that workplace incivility was positively correlated with anxiety (r=0.371, p<0.01) and job burn-out (r=0.238, p<0.01) of new nurses. The positive relation between anxiety (β=0.364, p<0.01) and job burn-out (β=0.240, p<0.01) was also significant. Moreover, anxiety partially mediated (z=7.807, p<0.01) and resilience moderated (β=−0.564, p<0.01) the association between workplace incivility and job burn-out. Conclusion Experience of workplace incivility by new nurses would likely generate anxiety in the victims. Further, the increased anxiety state could elevate their level of job burn-out. New nurses with high levels of resilience could buffer the negative influence of workplace incivility by using a positive coping style. PMID:29626049

Broadcasting information anonymously becomes more difficult as surveillance technology improves, but remarkably, quantum protocols exist that enable provably traceless broadcasting. The difficulty is making scalable entangled resource states that are robust to errors. We propose an anonymous broadcasting protocol that uses a continuous-variable surface-code state that can be produced using current technology. High squeezing enables large transmission bandwidth and strong anonymity, and the topological nature of the state enables local error mitigation.

Testing for HIV without permission.

Gillon, R

1987-03-28

A proposal has been made by R. Doll ("A proposal for doing prevalence studies of AIDS," British Medical Journal 1987 Feb 14; 294(6569): 244) to carry out anonymous screening for AIDS on blood samples taken in hospitals for other purposes. Gillon analyzes ethical objections to the proposal: (1) the testing--which constitutes nontherapeutic research--would be done without the patient's consent; and (2) patients could not be told whether they have HIV antibodies even if they wished to know. He denies that a patient who lets blood be taken for testing is giving implied consent for the use of that blood for purposes other than the patient's benefit. Included with his article is an inset "outline proposal for obtaining implied consent to prevalence studies for HIV antibody." It calls for leaflets to be given to patients explaining the research goal, the implications for the patient, and the fact that permission for such testing will be assumed unless explicitly withheld.

South Africa has one of the highest HIV prevalences in the world, and compared with other sectors of the national economy, the construction industry is disproportionately adversely affected. Using data collected nationally from more than 57,000 construction workers, HIV infection among South African construction workers was estimated, together with an assessment of the association between worker HIV serostatus and worker characteristics of gender, age, nature of employment, occupation, and HIV testing history. The HIV infection of construction workers was estimated to be lower than that found in a smaller 2008 sample. All worker characteristics are significantly associated with HIV serostatus. In terms of most at-risk categories: females are more at risk of HIV infection than males; workers in the 30-49 year old age group are more at risk than other age groups; workers employed on a less permanent basis are more at risk; as are workers not having recently tested for HIV. Among occupations in the construction industry, general workers, artisans, and operator/drivers are those most at risk. Besides yielding more up-to-date estimated infection statistics, this research also identifies vulnerable sub-groups as valuable pointers for more targeted workplace interventions by construction firms.

Since 2008, the Singapore Ministry of Health (MOH) has expanded HIV testing by increasing anonymous HIV test sites, as well as issuing a directive to hospitals to offer routine voluntary opt out inpatient HIV testing. We reviewed this program implemented at the end of 2008 at Tan Tock Seng Hospital (TTSH), the second largest acute care general hospital in Singapore. From January 2009 to December 2010, all inpatients aged greater or equal than 21 years were screened for HIV unless they declined or were not eligible for screening. We reviewed the implementation of the Opt Out testing policy. There were a total of 93,211 admissions; 41,543 patients were included based on HIV screening program eligibility criteria. Among those included, 79% (n = 32,675) opted out of HIV screening. The overall acceptance rate was 21%. Majority of eligible patients who were tested (63%) were men. The mean age of tested patients was 52 years. The opt out rate was significantly higher among females (OR: 1.5, 95%CI: 1.4-1.6), aged >60 years (OR: 2.3, 95%CI: 2.2-2.4) and Chinese ethnicity (OR: 1.7, 95%CI:1.6-1.8). The false positive rate of the HIV screening test is 0.56%. The proportion of patients with HIV infection among those who underwent HIV screening is 0.18%. All 16 confirmed HIV patients were linked to care. The default opt-in rate of inpatient HIV testing was low at Tan Tock Seng Hospital, Singapore. Efforts to address individual HIV risk perception and campaigns against HIV stigma are needed to encourage more individuals to be tested for HIV.

The spread of human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) epidemic in the worldwide trend is not contained effectively. The pregnant women infected HIV seriously in the high HIV epidemic areas in China. The transmission of HIV to child may be cut off if HIV positive mother was found early by HIV testing. Pregnant women mandatorily received the HIV counseling and testing services. Most of them did not know the knowledge about HIV prevention and were not willing to receive HIV testing actively. Willingness for HIV testing among pregnant women was investigated, which can help to promote them to take up HIV testing actively. This study assessed the prevalence of the willingness for HIV testing and cognitive factors associated with it. A cross-sectional survey was conducted to 500 pregnant women via face-to-face interviews with anonymous structured questionnaire guided by the Health Belief Model (HBM). The prevalence of the willingness for HIV testing was 58.60%. Perceived higher susceptibility to HIV (multivariate-adjusted odds ratio (ORm) = 2.02, 95% confidence interval (CI): 1.40-5.06), more knowledge for HIV (ORm = 1.92, 95% CI: 1.11-3.87) and perceived less social stigma (ORm = 0.80, 95% CI: 0.34-0.91) were associated with higher willingness for HIV testing among pregnant women. To prevent HIV mother to children transmission, it is necessary to enhance knowledge for HIV, change cognitive factors and increase willingness for HIV testing among pregnant women.

HIV prevalence data collected from routine HIV testing of pregnant women at antenatal clinics (ANC-RT) are potentially available from all facilities that offer testing services to pregnant women and can be used to improve estimates of national and subnational HIV prevalence trends. We develop methods to incorporate these new data source into the Joint United Nations Programme on AIDS Estimation and Projection Package in Spectrum 2017. We develop a new statistical model for incorporating ANC-RT HIV prevalence data, aggregated either to the health facility level (site-level) or regionally (census-level), to estimate HIV prevalence alongside existing sources of HIV prevalence data from ANC unlinked anonymous testing (ANC-UAT) and household-based national population surveys. Synthetic data are generated to understand how the availability of ANC-RT data affects the accuracy of various parameter estimates. We estimate HIV prevalence and additional parameters using both ANC-RT and other existing data. Fitting HIV prevalence using synthetic data generally gives precise estimates of the underlying trend and other parameters. More years of ANC-RT data should improve prevalence estimates. More ANC-RT sites and continuation with existing ANC-UAT sites may improve the estimate of calibration between ANC-UAT and ANC-RT sites. We have proposed methods to incorporate ANC-RT data into Spectrum to obtain more precise estimates of prevalence and other measures of the epidemic. Many assumptions about the accuracy, consistency, and representativeness of ANC-RT prevalence underlie the use of these data for monitoring HIV epidemic trends and should be tested as more data become available from national ANC-RT programs.

Self-organized Anonymous Authentication in Mobile Ad Hoc Networks

NASA Astrophysics Data System (ADS)

Freudiger, Julien; Raya, Maxim; Hubaux, Jean-Pierre

Pervasive communications bring along new privacy challenges, fueled by the capability of mobile devices to communicate with, and thus “sniff on”, each other directly. We design a new mechanism that aims at achieving location privacy in these forthcoming mobile networks, whereby mobile nodes collect the pseudonyms of the nodes they encounter to generate their own privacy cloaks. Thus, privacy emerges from the mobile network and users gain control over the disclosure of their locations. We call this new paradigm self-organized location privacy. In this work, we focus on the problem of self-organized anonymous authentication that is a necessary prerequisite for location privacy. We investigate, using graph theory, the optimality of different cloak constructions and evaluate with simulations the achievable anonymity in various network topologies. We show that peer-to-peer wireless communications and mobility help in the establishment of self-organized anonymous authentication in mobile networks.

Throughout Europe, differences in satisfaction with HIV-care of people living with HIV (PLHIV) persist, despite a tendency towards harmonisation of policy and management. A European sample of 1,549 PLHIV responded to an anonymous questionnaire assessing demographic background, general health, mental health, sexual health, and HIV-service provision. We compared the results across 3 regions: Western, Southern and Central/Eastern Europe. PLHIV differed in several socio-demographic variables (gender, migrant status, sexual orientation, and financial situation) as well as specific psychosocial aspects (HIV-related discrimination, satisfaction with sexual and reproductive health (SRH) services in HIV-care settings, and complaints about service provision). Using multivariate analysis, a predictive model for satisfaction with SRH services in HIV clinics was developed, resulting into region of residence, and participants' satisfaction with their own health status as significant predictors. Better integration of SRH services in HIV-care should be encouraged. Service providers should be trained and encouraged to discuss SRH issues with their patients to create a supportive environment, free of discrimination. More time should be allocated to discuss SRH issues with individual patients.

To characterize pregnant patients' knowledge, attitudes and preferences regarding antenatal HIV testing for themselves and their sexual partners. Observational, mixed methods study of HIV-negative pregnant women from a university-based urban clinic. Participants completed an anonymous survey about HIV testing for themselves and their partners. Descriptive statistics, bivariable analyses, multivariable logistic regression and qualitative thematic analysis were utilized. One hundred and forty-two patients (mean age 28.6±5.5 years) participated. A majority (57.7%) were married or partnered, and 92.9% reported having at least one current sexual partner. Although a majority (62.8%) reported their partner had a prior HIV test, and 93.0% of these women were aware of test results, only 20.7% reported partner testing had occurred in the past 6 months. Women who had a prior HIV test, who were older or who were non-white were more likely to be aware of their partner's HIV status. A majority (66.9%) of women desired knowledge of their partner's current status and 76.0% believed their partners would like to know his HIV status; in addition, 74% were interested in receiving partner testing at the site of prenatal care. Qualitative analysis demonstrated that health concerns and believing HIV knowledge is important to the relationship were motivators for desiring partner testing. In this urban community, a majority of pregnant women do not know HIV test results of their sexual partner during the current pregnancy. Women desired to know their partner's HIV status and were receptive to partner testing at the site of prenatal care or other locations. Partner testing may be a critical step toward elimination of seroconversion during pregnancy and maternal-to-child HIV transmission.

Prevalence rates of work-related stress, depression, and anxiety are high, resulting in reduced productivity and increased absenteeism. There is evidence that these conditions can be successfully treated in the workplace, but take-up of psychological treatments among workers is low. Digital mental health interventions delivered in the workplace may be one way to address this imbalance, but although there is evidence that digital mental health is effective at treating stress, depression, and anxiety in the workplace, uptake of and engagement with these interventions remains a concern. Additionally, there is little research on the appropriateness of the workplace for delivering these interventions or on what the facilitators and barriers to engagement with digital mental health interventions in an occupational setting might be. The aim of this research was to get a better understanding of the facilitators and barriers to engaging with digital mental health interventions in the workplace. Semistructured interviews were held with 18 participants who had access to an occupational digital mental health intervention as part of a randomized controlled trial. The interviews were transcribed, and thematic analysis was used to develop an understanding of the data. Digital mental health interventions were described by interviewees as convenient, flexible, and anonymous; these attributes were seen as being both facilitators and barriers to engagement in a workplace setting. Convenience and flexibility could increase the opportunities to engage with digital mental health, but in a workplace setting they could also result in difficulty in prioritizing time and ensuring a temporal and spatial separation between work and therapy. The anonymity of the Internet could encourage use, but that benefit may be lost for people who work in open-plan offices.

Employment sustainability is one of the most pressing issues inflicting people living with HIV (PLHIV). A qualitative approach was used to elucidate the perceived challenges in sustaining their employment and the perceived barriers in re-entering the workforce for HIV patients. In-depth interviews were conducted with 16 patients from an acute hospital in Singapore. The main challenges raised in sustaining employment were: (1) ability to ensure secrecy of diagnosis from employers, (2) ability to secure financial resources for treatment and sustenance, (3) ability to ensure stable health to meet job requirements, (4) ability to cognitively sit with the concerns of uncertainty and limitations in career, and (5) ability to work through discriminatory workplace practices. The perceived barriers in gaining workforce re-entry were: (1) fear of pre-employment medical screening and potential discriminatory practices at workplace, (2) concerns over health (frequent hospital admissions, physical weakness, and existing medical co-morbidities), and (3) psychosocial challenges (unstable accommodation, older age, financial issues, and trade skills limitation). The overarching factor that influences the success of sustaining and securing an employment among HIV patients is secrecy of the diagnosis. The individuals' health status, financial status and access to healthcare, and other psychosocial challenges further compound the issue.

We sought to identify the socioeconomic impact on people living with HIV (PLWH) in Sudan. Focus group discussions were used to collect data and identify the most outstanding domains of HIV impact on PLWH and the survival mechanisms that may be common to a group of diverse HIV-infected persons (n = 30). The findings indicated that the most striking financial and social impacts were due to stigma associated with HIV in the conservative Sudanese society, which led to loss of work with all its consequences (e.g., children's education and health care expenses were affected). The socioeconomic impacts of HIV on infected populations are discussed, and suggestions for possible interventions to mitigate harmful impacts and stigma within the society, the workplace, and health care settings are highlighted. We concluded that HIV has intensified the existing problems of infected people, contributing to their vulnerability to poverty. Copyright © 2016 Association of Nurses in AIDS Care.

An anonymous authentication scheme for roaming services in global mobility networks allows a mobile user visiting a foreign network to achieve mutual authentication and session key establishment with the foreign-network operator in an anonymous manner. In this work, we revisit He et al.'s anonymous authentication scheme for roaming services and present previously unpublished security weaknesses in the scheme: (1) it fails to provide user anonymity against any third party as well as the foreign agent, (2) it cannot protect the passwords of mobile users due to its vulnerability to an offline dictionary attack, and (3) it does not achieve session-key security against a man-in-the-middle attack. We also show how the security weaknesses of He et al.'s scheme can be addressed without degrading the efficiency of the scheme.

Studies of HIV stigma in China are becoming more prevalent, but these studies have seldom involved direct cross-cultural comparisons. Moreover, although researchers consider employers to be a key power group whose practices can significantly impact the adjustment and recovery of people with HIV, the attitudes of employers in China towards people with HIV have rarely been studied. The present study sought to investigate employers' attitudes and hiring practices towards people with HIV across three culturally and linguistically distinct cities: Chicago, Beijing, and Hong Kong. One hundred employers from a broad spectrum of firm types were interviewed across the three cities, and their qualitative data were analyzed for information about the processes behind employer practices in hiring people with HIV. Employers from all three cities showed reluctance to hire people with HIV, but this trend was most pronounced with employers from Beijing and Hong Kong. Concerns about biological contagion were apparent in all three cities. Social contagion, or the belief that people with HIV could morally corrupt those around them, was a particular concern of employers from Beijing and Hong Kong. The concerns about hiring people with HIV in Hong Kong and Beijing may be related to specific cultural dynamics related to loss of 'face', level of contact and knowledge about people with HIV, and the psychological interconnectedness between people in society. In sum, employers in all three cities showed concerns about hiring people with HIV, but at the same time, their attitudes about discriminating against people with HIV differed widely across the cities.

Care coordination programmes are an important aspect of HIV management whose success depends largely on HIV primary care provider (PCP) and case manager collaboration. Factors influencing collaboration among HIV PCPs and case managers remain to be studied. The study objective was to test an existing theoretical model of interprofessional collaborative practice and determine which factors play the most important role in facilitating collaboration. A self-administered, anonymous mail survey was sent to HIV PCPs and case managers in New York City. An adapted survey instrument elicited information on demographic, contextual, and perceived social exchange (trustworthiness, role specification, and relationship initiation) characteristics. The dependent variable, perceived interprofessional practice, was constructed from a validated scale. A sequential block wise regression model specifying variable entry order examined the relative importance of each group of factors and of individual variables. The analysis showed that social exchange factors were the dominant drivers of collaboration. Relationship initiation was the most important predictor of interprofessional collaboration. Additional influential factors included organisational leadership support of collaboration, practice settings, and frequency of interprofessional meetings. Addressing factors influencing collaboration among providers will help public health programmes optimally design their structural, hiring, and training strategies to foster effective social exchanges and promote collaborative working relationships.

Privacy, anonymity and subjectivity in genomic research.

The use of non-anonymized human genome data is becoming increasingly popular in research. Here we review the proceedings of a special meeting on this topic that took place at European Molecular Biology Organization (EMBO) in December 2014. The main points discussed centered on how to achieve 'anonymity,' 'trust,' and 'protection of data' in relation to new genomic technologies and research. Following our report of this meeting, we also raise three further issues for future consideration: the harmonization of international law in relation to genetic data protection; the complex issues around the 'dividual' nature of genetic data; and the growing commercial value of personal data. In conclusion, we stress the importance of scientists working in the area of genomic research engaging in interdisciplinary collaborations with humanities and social science scholars and addressing these complicated issues.

This article addresses competency-based standards and guidelines for the involvement of speech-language pathologists in the workplace of clients who stutter. It advocates broadening customary practices in stuttering treatment and suggests that speech-language pathologists should extend their scope of service delivery to the workplace. It presents a sequence for the collaborative involvement of the employer and other workplace members and proposes strategies for evaluating workplace based fluency programs. Issues of fluency management, transfer, maintenance, and efficacy are discussed in the workplace context. Also addressed is workplace communication as well as such factors as stereotypes, discrimination, and resistance to change which may impinge on workplace intervention. It is argued that structured intervention, transfer, and generalization within a collaborative workplace framework facilitates best practice for the fluency clinician and more appropriate outcomes for the diversity of clients who stutter.

The anonymity paradox in patient engagement: reputation, risk and web-based public feedback.

PubMed

Speed, Ewen; Davison, Charlie; Gunnell, Caroline

2016-06-01

The UK National Health Service (NHS) has long espoused patient and public engagement. Recent years have seen increasing use of internet-based methods of collecting feedback about patient experience and public and staff views about NHS services and priorities. Often hailed as a means of facilitating participative democratic patient engagement, these processes raise a number of complex issues. A key aspect of it is the opportunity for comment to be made anonymously. Our research reveals an anonymity paradox whereby patients clearly demonstrate a perception that anonymity is a prerequisite for effective use of these feedback processes, whereas professionals demonstrate a perception that patient anonymity is a barrier to effective use. The risks of anonymity are constructed very differently by patients and professionals. Patient concerns around anonymity were not motivated by a general concern about a loss of privacy, but more that a positive identification might compromise future care. For professionals, concerns were voiced more around risks of reputational damage for specific practitioners or practices (in that anyone could say anything) and also that this anonymous feedback was available publicly and that it might go against the medical opinion of the professional. These concerns pointed to important differences in perceptions of patient and professional vulnerability. In the qualitative analysis that follows the key finding was that while anonymity makes service users feel less vulnerable, it can have the opposite effect on managers and clinical staff. This raises important implications for the use and utility of internet-based methods of collecting patient feedback. Published by the BMJ Publishing Group Limited.

2012-01-01

Introduction Since 2008, the Singapore Ministry of Health (MOH) has expanded HIV testing by increasing anonymous HIV test sites, as well as issuing a directive to hospitals to offer routine voluntary opt out inpatient HIV testing. We reviewed this program implemented at the end of 2008 at Tan Tock Seng Hospital (TTSH), the second largest acute care general hospital in Singapore. Methods and Findings From January 2009 to December 2010, all inpatients aged greater or equal than 21 years were screened for HIV unless they declined or were not eligible for screening. We reviewed the implementation of the Opt Out testing policy. There were a total of 93,211 admissions; 41,543 patients were included based on HIV screening program eligibility criteria. Among those included, 79% (n = 32,675) opted out of HIV screening. The overall acceptance rate was 21%. Majority of eligible patients who were tested (63%) were men. The mean age of tested patients was 52 years. The opt out rate was significantly higher among females (OR: 1.5, 95%CI: 1.4–1.6), aged >60 years (OR: 2.3, 95%CI: 2.2–2.4) and Chinese ethnicity (OR: 1.7, 95%CI:1.6–1.8). The false positive rate of the HIV screening test is 0.56%. The proportion of patients with HIV infection among those who underwent HIV screening is 0.18%. All16 confirmed HIV patients were linked to care. Conclusion The default opt-in rate of inpatient HIV testing was low at Tan Tock Seng Hospital, Singapore. Efforts to address individual HIV risk perception and campaigns against HIV stigma are needed to encourage more individuals to be tested for HIV. PMID:22493708

SummaryA questionnaire survey on the knowledge about human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) and attitudes to voluntary counselling and testing (VCT) in pregnancy of 334 antenatal attendants at Komfo Anokye Teaching Hospital (KATH) was conducted. The survey showed that HIV/AIDS is recognized as a life-threatening condition and is mainly acquired through unprotected sexual intercourse with an infected partner, use of unsterile sharp instruments and blood transfusion. Knowledge about mother to child transmission (MTCT) was lacking.The majority of women who had done the test did so as a pre-requisite for church blessing of their marriage.VCT would be acceptable especially when anonymity is ensured and drug treatment is available for mother and child should the pregnant woman test positive for HIV.

The aim of the authors of the present study was to investigate gender differences in the levels of posttraumatic stress symptoms (PTSS) and social support in a Polish sample of HIV+ men (n = 613) and women (n = 230). This was an anonymous cross-sectional study, and participation was voluntary. The research questionnaires were distributed in paper form among patients of Warsaw's Hospital for Infectious Diseases from January to October 2015. The level of PTSS was assessed using the PTSD Factorial Version Inventory. Social support was assessed using the Berlin Social Support Scales. HIV+ women scored higher on all PTSS dimensions compared to HIV+ men. HIV+ women were characterized by a higher need for support and more support actually received compared to HIV+ men. We observed a positive association between HIV infection duration and AIDS phase and the global trauma score only among HIV+ men. The moderation analysis also revealed a positive relationship between actual received support and the global trauma score among HIV+ women only. Increased clinician awareness is needed about the role of PTSS and social support among people living with HIV, especially taking gender differences into account.

Internet-based recruitment system for HIV and STI screening for men who have sex with men in Estonia, 2013: analysis of preliminary outcomes.

PubMed

Ruutel, K; Lohmus, L; Janes, J

2015-04-16

The aim of the current project was to develop an Internet-based recruitment system for HIV and sexually transmitted infection (STI) screening for men who have sex with men (MSM) in Estonia in order to collect biological samples during behavioural studies. In 2013, an Internet-based HIV risk-behaviour survey was conducted among MSM living in Estonia. After completing the questionnaire, all participants were offered anonymous and free-of-charge STI testing. They could either order a urine sample kit by post to screen for chlamydia infections (including lymphogranuloma venereum (LGV)), trichomoniasis, gonorrhoea and Mycoplasma genitalium infections, or visit a laboratory for HIV, hepatitis A virus, hepatitis B virus,hepatitis C virus and syphilis screening. Of 301 participants who completed the questionnaire, 265 (88%),reported that they were MSM. Of these 265 MSM,68 (26%) underwent various types of testing. In the multiple regression analysis, Russian as the first language,previous HIV testing and living in a city or town increased the odds of testing during the study. Linking Internet-based behavioural data collection with biological sample collection is a promising approach. As there are no specific STI services for MSM in Estonia,this system could also be used as an additional option for anonymous and free-of-charge STI screening.

Opening the Door to Zero New HIV Infections in Closed Settings.

Prisons and other closed settings are high-risk environments for HIV and tuberculosis (TB) transmission. Prisoners often experience overcrowded living conditions and violence-including sexual assault-increasing their vulnerability to HIV and TB. However, high infection rates in prisons affect both prisoners and prison employees. Both groups, in interacting with their families and their communities, represent a potential risk of HIV transmission outside the prison setting. National HIV and TB strategies should therefore include measures to prevent transmission and increase access to HIV-related services in prisons. Courts have progressively recognized the human rights of prisoners, including the right to health and access to HIV-related services. A number of national and regional court decisions have affirmed that prison authorities have a duty of care to prisoners and an obligation to ensure that prisoners have access to HIV prevention measures and treatment. Policies and programs on HIV, AIDS, and TB for prison workplaces that are aligned with the ILO's international labor standards can benefit both prisoners and prison employees. In particular, the ILO's HIV and AIDS Recommendation, 2010 (No. 200) affirms the principle of universal access to HIV services and provides guidance for the HIV/TB response in prison settings.

Bayesian modeling of consumer behavior in the presence of anonymous visits

NASA Astrophysics Data System (ADS)

Novak, Julie Esther

Tailoring content to consumers has become a hallmark of marketing and digital media, particularly as it has become easier to identify customers across usage or purchase occasions. However, across a wide variety of contexts, companies find that customers do not consistently identify themselves, leaving a substantial fraction of anonymous visits. We develop a Bayesian hierarchical model that allows us to probabilistically assign anonymous sessions to users. These probabilistic assignments take into account a customer's demographic information, frequency of visitation, activities taken when visiting, and times of arrival. We present two studies, one with synthetic and one with real data, where we demonstrate improved performance over two popular practices (nearest-neighbor matching and deleting the anonymous visits) due to increased efficiency and reduced bias driven by the non-ignorability of which types of events are more likely to be anonymous. Using our proposed model, we avoid potential bias in understanding the effect of a firm's marketing on its customers, improve inference about the total number of customers in the dataset, and provide more precise targeted marketing to both previously observed and unobserved customers.

Background Participants in medical forums often reveal personal health information about themselves in their online postings. To feel comfortable revealing sensitive personal health information, some participants may hide their identity by posting anonymously. They can do this by using fake identities, nicknames, or pseudonyms that cannot readily be traced back to them. However, individual writing styles have unique features and it may be possible to determine the true identity of an anonymous user through author attribution analysis. Although there has been previous work on the authorship attribution problem, there has been a dearth of research on automated authorship attribution on medical forums. The focus of the paper is to demonstrate that character-based author attribution works better than word-based methods in medical forums. Objective The goal was to build a system that accurately attributes authorship of messages posted on medical forums. The Authorship Attributor system uses text analysis techniques to crawl medical forums and automatically correlate messages written by the same authors. Authorship Attributor processes unstructured texts regardless of the document type, context, and content. Methods The messages were labeled by nicknames of the forum participants. We evaluated the system’s performance through its accuracy on 6000 messages gathered from 2 medical forums on an in vitro fertilization (IVF) support website. Results Given 2 lists of candidate authors (30 and 50 candidates, respectively), we obtained an F score accuracy in detecting authors of 75% to 80% on messages containing 100 to 150 words on average, and 97.9% on longer messages containing at least 300 words. Conclusions Authorship can be successfully detected in short free-form messages posted on medical forums. This raises a concern about the meaningfulness of anonymous posting on such medical forums. Authorship attribution tools can be used to warn consumers wishing to post

Assessing Willingness to Test for HIV among Men who have Sex with Men Using Conjoint Analysis, Evidence for Uptake of the FDA-approved at-Home HIV Test

PubMed Central

Lee, Sung-Jae; Brooks, Ronald; Bolan, Robert K.; Flynn, Risa

2013-01-01

Men who have sex with men (MSM) in the United States represent a vulnerable population with lower rates of HIV testing. There are various specific attributes of HIV testing that may impact willingness to test (WTT) for HIV. Identifying specific attributes influencing patients’ decisions around WTT for HIV is critical to ensure improved HIV testing uptake. This study examined WTT for HIV by using conjoint analysis, an innovative method for systematically estimating consumer preferences across discrete attributes. WTT for HIV was assessed across eight hypothetical HIV testing scenarios varying across seven dichotomous attributes: location (home vs. clinic), price (free vs. $50), sample collection (finger prick vs. blood), timeliness of results (immediate vs. 1–2 weeks), privacy (anonymous vs. confidential), results given (by phone vs. in-person), and type of counseling (brochure vs. in-person). Seventy-five MSM were recruited from a community based organization providing HIV testing services in Los Angeles to participate in conjoint analysis. WTT for HIV score was based on a 100-point scale. Scores ranged from 32.2 to 80.3 for eight hypothetical HIV testing scenarios. Price of HIV testing (free vs. $50) had the highest impact on WTT (impact score=31.4, SD=29.2, p<.0001), followed by timeliness of results (immediate vs. 1–2 weeks) (impact score=13.9, SD=19.9, p=<.0001) and testing location (home vs. clinic) (impact score=10.3, SD=22.8, p=.0002). Impacts of other HIV testing attributes were not significant. Conjoint analysis method enabled direct assessment of HIV testing preferences and identified specific attributes that significantly impact WTT for HIV among MSM. This method provided empirical evidence to support the potential uptake of the newly FDA-approved over-the-counter HIV home-test kit with immediate results, with cautionary note on the cost of the kit.

The relationship between young adults' beliefs about anonymity and subsequent cyber aggression.

PubMed

Wright, Michelle F

2013-12-01

Anonymity is considered a key motivator for cyber aggression, but few investigations have focused on the connection between anonymity and the subsequent engagement in aggression through the cyber context. The present longitudinal study utilized structural equation modeling to reveal indirect associations between two types of anonymity (i.e., punishment by authority figures and retaliation from the target) and later cyber aggression among 130 young adults. These relationships were examined through the influence of beliefs about not getting caught and not believing in the permanency of online content. Findings indicated that both forms of anonymity were related to cyber aggression 6 months later through two explanatory mechanisms (i.e., confidence with not getting caught and believing online content is not permanent), after controlling for gender and cyber aggression at Time 1. The implications of these findings are discussed, and an appeal for additional research investigating cyber aggression among young adults is given.

De-identification of health records using Anonym: effectiveness and robustness across datasets.

Evaluate the effectiveness and robustness of Anonym, a tool for de-identifying free-text health records based on conditional random fields classifiers informed by linguistic and lexical features, as well as features extracted by pattern matching techniques. De-identification of personal health information in electronic health records is essential for the sharing and secondary usage of clinical data. De-identification tools that adapt to different sources of clinical data are attractive as they would require minimal intervention to guarantee high effectiveness. The effectiveness and robustness of Anonym are evaluated across multiple datasets, including the widely adopted Integrating Biology and the Bedside (i2b2) dataset, used for evaluation in a de-identification challenge. The datasets used here vary in type of health records, source of data, and their quality, with one of the datasets containing optical character recognition errors. Anonym identifies and removes up to 96.6% of personal health identifiers (recall) with a precision of up to 98.2% on the i2b2 dataset, outperforming the best system proposed in the i2b2 challenge. The effectiveness of Anonym across datasets is found to depend on the amount of information available for training. Findings show that Anonym compares to the best approach from the 2006 i2b2 shared task. It is easy to retrain Anonym with new datasets; if retrained, the system is robust to variations of training size, data type and quality in presence of sufficient training data.

Peripartal transmission of human immunodeficiency virus (HIV) and Treponema pallidum, the causative agent of syphilis, leads to severe consequences for newborns. Preventive measures require awareness of the maternal infection. Although HIV and syphilis testing in Madagascar could be theoretically carried out within the framework of the national pregnancy follow-up scheme, the required test kits are rarely available at peripheral health centres. In this study, we screened blood samples of pregnant Madagascan women for HIV and syphilis seroprevalence to estimate the demand for systemic screening in pregnancy. Retrospective anonymous serological analysis for HIV and syphilis was performed in plasma samples from 1232 pregnant women that were taken between May and July 2010 in Ambositra, Ifanadiana, Manakara, Mananjary, Moramanga and Tsiroanomandidy (Madagascar) during pregnancy follow-up. Screening was based on Treponema pallidum haemagglutination tests for syphilis and rapid tests for HIV, with confirmation of positive screening results on line assays. Out of 1232 pregnant women, none were seropositive for HIV and 37 (3%) were seropositive for Treponema pallidum. Our findings are in line with previous studies that describe considerable syphilis prevalence in the rural Madagascan population. The results suggest a need for screening to prevent peripartal Treponema pallidum transmission, while HIV is still rare. If they are known, Treponema pallidum infections can be easily, safely and inexpensively treated even in pregnancy to reduce the risk of transmission. © 2012 Blackwell Publishing Ltd.

The HIV epidemic in Peru is concentrated among men who have sex with men (MSM). Given that MSM have been documented as early adopters of emerging technology, we examined communication technology access and utilization, and mobile health (mHealth) acceptance among Peruvian MSM and transgender women (TGW) in order to gauge opportunities for mHealth-enabled HIV interventions. A convenience sample of 359 HIV-infected MSM and TGW recruited from three sites in Lima, Peru completed standardized assessments of alcohol use disorders (AUDs), risky sexual behavior, and antiretroviral therapy (ART) adherence along with self-constructed measures of communication technology access and utilization, and mHealth acceptance. Most participants (86%) had daily access to any cell phone, including smartphones (30%). The most frequent communication activities were receiving and making calls, and receiving and sending text messages using cell phones. On a 5-point Likert scale, participants expressed interest in using mHealth for medication reminders (M = 3.21, SD = 1.32) and engaging in anonymous online interactions with health professionals to discuss HIV-related issues (M = 3.56, SD = 1.33). Importantly, no significant differences were found in communication technology use and mHealth acceptance among participants with AUDs, depression, and suboptimal ART adherence, all of which are associated with poor HIV treatment outcomes. Findings show support for implementing mHealth-based intervention strategies using cell phones to assess and reduce HIV-risk behaviors among HIV-infected MSM and TGW.

The HIV epidemic in Peru is concentrated among men who have sex with men (MSM). Given that MSM have been documented as early adopters of emerging technology, we examined communication technology access and utilization, and mobile health (mHealth) acceptance among Peruvian MSM and transgender women (TGW) in order to gauge opportunities for mHealth-enabled HIV interventions. A convenience sample of 359 HIV-infected MSM and TGW recruited from three sites in Lima, Peru completed standardized assessments of alcohol use disorders (AUDs), risky sexual behavior, and antiretroviral therapy (ART) adherence along with self-constructed measures of communication technology access and utilization, and mHealth acceptance. Most (86%) participants had daily access to any cell phone, including smartphones (30%). The most frequent communication activities were receiving and making calls, and receiving and sending text messages using cell phones. On a 5-point Likert scale, participants expressed interest in using mHealth for medication reminders (M=3.21, SD=1.32) and engaging in anonymous online interactions with health professionals to discuss HIV-related issues (M=3.56, SD=1.33). Importantly, no significant differences were found in communication technology use and mHealth acceptance among participants with AUDs, depression and suboptimal ART adherence, all of which are associated with poor HIV treatment outcomes. Findings show support for implementing mHealth-based intervention strategies using cell phones to assess and reduce HIV-risk behaviors among HIV-infected MSM and TGW. PMID:25285464

Diagnostic radiology resident assessment has evolved from a traditional oral examination to computerized testing. Teaching faculty struggle to reconcile the differences between traditional teaching methods and residents' new preferences for computerized testing models generated by new examination styles. We aim to summarize the collective experiences of senior residents at three different teaching hospitals who participated in case review sessions using a computer-based, interactive, anonymous teaching tool, rather than the Socratic method. Feedback was collected from radiology residents following participation in a senior resident case review session using Nearpod, which allows residents to anonymously respond to the teaching material. Subjective resident feedback was uniformly enthusiastic. Ninety percent of residents favor a case-based board review incorporating multiple-choice questions, and 94% favor an anonymous response system. Nearpod allows for inclusion of multiple-choice questions while also providing direct feedback to the teaching faculty, helping to direct the instruction and clarify residents' gaps in knowledge before the Core Examination.

Workplace ART programmes: Why do companies invest in them and are they working?

PubMed

George, Gavin

2006-09-01

Prevalence data indicates that certain sectors within the private sector are particularly affected by HIV/AIDS. Companies in southern Africa began implementing treatment programmes in early 2002 as the corporate sector came to realise the financial imperative of offsetting employee morbidity and mortality. This article sets about to explain the rationale behind antiretroviral treatment (ART) programmes within the private sector while uncovering some of the obstacles businesses face when treating HIV-infected employees. Data suggest that in many cases employees' uptake of voluntary counselling and testing (VCT) and ART are slow. At this early stage of workplace treatment provision, data indicate that employers must seek ways to increase uptake of VCT and treatment in an attempt to make programmes more cost-effective.

Due to their geographical mobility and long periods of separation from intimate partners, migrant workers are at increased risk for a variety of sexually transmitted infections (STIs) including HIV/AIDS. This study sought to investigate patterns in HIV/AIDS related knowledge, attitudes and sexual behaviour in migrant workers in Croatia. In 2003, 566 male migrant workers were recruited during regular required medical examinations and surveyed at seven locations throughout the country. Each participant was asked to complete a self-administered KABP (sexual knowledge, attitudes, beliefs and practices) questionnaire. The average age of respondents was 38.2 years and the majority worked as seafarers (77.3%) and construction workers (20.5%). Only 18.5% of respondents were able to correctly answer all 13 questions assessing knowledge of HIV/AIDS. Seafarers reported higher levels of knowledge than did construction workers. The average respondent reported having had two sexual partners in the last 12 months, with slightly over half of the respondents (55.3%) reporting condom use at their last intercourse with a casual partner. One fifth of the respondents (20.3%) who reported having had intercourse with a sex worker during the last year reported not using condoms at last intercourse. The number of sexual partners was correlated with age, marital status, faith in God, and personal HIV risk assessment. Attitudes toward condom use, co-workers' HIV/AIDS concerns and the duration of migrant status (within the last two years) were shown to be significant correlates of condom use at last intercourse with a casual partner. The effect of HIV/AIDS related knowledge on analyzed behaviors did not reach statistical significance. Inadequate patterns of migrant workers' condom use, gaps in knowledge about HIV transmission and modes of protection, as well as widespread ignorance regarding available anonymous HIV testing found by this study suggest a critical need for expert intervention to

Anonymizing and Sharing Medical Text Records

Li, Xiao-Bai; Qin, Jialun

2017-01-01

Health information technology has increased accessibility of health and medical data and benefited medical research and healthcare management. However, there are rising concerns about patient privacy in sharing medical and healthcare data. A large amount of these data are in free text form. Existing techniques for privacy-preserving data sharing deal largely with structured data. Current privacy approaches for medical text data focus on detection and removal of patient identifiers from the data, which may be inadequate for protecting privacy or preserving data quality. We propose a new systematic approach to extract, cluster, and anonymize medical text records. Our approach integrates methods developed in both data privacy and health informatics fields. The key novel elements of our approach include a recursive partitioning method to cluster medical text records based on the similarity of the health and medical information and a value-enumeration method to anonymize potentially identifying information in the text data. An experimental study is conducted using real-world medical documents. The results of the experiments demonstrate the effectiveness of the proposed approach. PMID:29569650

Internet-based interventions have potential to reduce HIV and STD transmission among men who meet male sexual partners online. From November 2009 to May 2010 we surveyed dating and hook-up website users (n = 3,050), website owners (n = 18), and health department HIV/STD directors (n = 81) to identify structural and behavioral prevention interventions that could be implemented online and which a majority of website users were willing to use, owners were willing to implement, and HIV/STD directors perceived to be effective. A majority of each of the three stakeholder groups agreed on the following: (1) automated HIV/STD testing reminders, (2) local STD test site directories, (3) links to sex-positive safe sex videos, (4) access to sexual health experts, (5) profile options to include safer sex preference, (6) chat rooms for specific sexual interests, (7) filtering partners by their profile information, and (8) anonymous e-card partner notification for STD exposure. Findings help build consensus about how to prioritize resources for implementing online HIV and STD prevention interventions and highlight differences between stakeholders to guide future discussion about how to advance prevention efforts.

Summary HIV-infected prisoners face an inordinate number of community re-entry challenges. In 2007, 102 HIV-infected prisoners in Malaysia were surveyed anonymously within six months prior to release to assess the prevalence and correlates of community re-entry challenges. Staying out of prison (60.8%), remaining off drugs (39.2%), finding employment (35.3%) and obtaining HIV care (32.4%) were the re-entry challenges reported most frequently. Global stigma, negative self-image and public attitudes-related stigma were independently associated with challenges to obtaining HIV care. In multivariate analyses, those with previous incarcerations (adjusted odds ratio [AOR], 3.2; 95% confidence interval [CI], 1.4–7.6), higher HIV-related symptoms (AOR, 2.0; 95% CI, 1.0–4.1) and higher public attitudes-related stigma (AOR, 2.5; 95% CI, 1.2–5.1) had a significantly higher likelihood of identifying more re-entry challenges. Targeted interventions, such as effective drug treatment, HIV care and public awareness campaigns, are crucial for stemming the HIV epidemic and improving health outcomes among HIV-infected prisoners in Malaysia.

We aim to understand the difference in stigma and discrimination, in particular sexual rejection, experienced between gay and heterosexual men living with HIV in the UK. The People Living with HIV StigmaSurvey UK 2015 recruited a convenience sample of persons with HIV through over 120 cross sector community organisations and 46 HIV clinics to complete an online survey. 1162 men completed the survey, 969 (83%) gay men and 193 (17%) heterosexual men, 92% were on antiretroviral therapy. Compared to heterosexual men, gay men were significantly more likely to report worrying about workplace treatment in relation to their HIV (21% vs. 11%), worrying about HIV-related sexual rejection (42% vs 21%), avoiding sex because of their HIV status (37% vs. 23%), and experiencing HIV-related sexual rejection (27% vs. 9%) in the past 12 months. In a multivariate logistic regression controlling for other sociodemographic factors, being gay was a predictor of reporting HIV-related sexual rejection in the past 12 months (aOR 2.17, CI 1.16, 4.02). Both gay and heterosexual men living with HIV experienced stigma and discrimination in the past 12 months, and this was higher for gay men in terms of HIV-related sexual rejection. Due to the high proportion of men reporting sexual rejection, greater awareness and education of the low risk of transmission of HIV among people on effective treatment is needed to reduce stigma and sexual prejudice towards people living with HIV.

Stigma, lack of knowledge and prevalence maintain HIV risk among Black Africans in New Zealand.

2015-02-01

The AfricaNZ Health project aimed explore HIV risks in Black African communities in NZ with a view to informing HIV infection prevention and health promotion programs. AfricaNZ Health was completed in two phases. The first developed desk estimates of the resident Black African population in New Zealand, and Africans living with HIV. The second comprised two arms: an anonymous survey administered at African community events and a series of focus groups around the country. High levels of knowledge and positive attitudes about HIV were more often found in older than younger age groups. Condom use was higher in the younger group than in older age groups. Traditional attitudes still inform some beliefs about HIV. Stigma about HIV and anyone at risk for HIV remains very high among Africans. Western sexual identity constructs are not meaningful. A culturally informed strategy for risk and stigma reduction is urgently needed. The existing prevention and care infrastructure, informed by MSM experiences, must address increased risk to Black African new settlers, but this is not a reason to discriminate or further stigmatise an already vulnerable population. © 2014 Public Health Association of Australia.

Ovarian hyperstimulation syndrome is a rare, but potentially life-threatening iatrogenic disorder arising from ovulation induction or ovarian hyperstimulation for assisted reproduction techniques. We report a case of a 26-year-old multiparous woman, an anonymous egg donor, who died a few hours after undergoing a procedure to donate eggs at an in vitro fertilization clinic. Her husband alleged that medical negligence had led to her death. The autopsy confirmed death due to ovarian hyperstimulation syndrome. We know of no previous descriptions of fatal ovarian hyperstimulation syndrome in an anonymous egg donor in medico-legal literature. © The Author(s) 2016.

Nationally, it has been estimated that 44% of adults in the United States have been tested for HIV, with substantial individual and community-level variations in HIV-testing attitudes and behaviors. HIV-testing behaviors and intentions and attitudes toward HIV testing, particularly toward home tests, were assessed among 385 adults recruited in a street intercept survey from a gay-identified agency, a substance-abuse treatment program, and inner-city community venues (a shopping mall and community center). Across these Los Angeles sites, the proportion of persons reported being tested for HIV in their lifetime (77%) was higher than the national estimate. Gay-identified agency (88%) and substance-abuse treatment program participants (99%) were more likely to have been tested than were the community participants (67%). Participants from a gay-identified agency were more likely to have had an anonymous test (51%) than were those from a substance-abuse treatment program (25%) or community sites (24%). Attitudes toward HIV testing, including mail-in home-test kits and instant home tests, were very positive. Most participants were willing to pay about $20 for a home-test kit. Participants from the community sites (82%) and the substance-abuse treatment program participants (87%) endorsed notification of HIV status to health departments and sexual partners more than did participants from the gay identified agency (48%). The street intercept survey appears to be a quick and feasible method to assess HIV testing in urban areas.

How safe are adolescents at Alcoholics Anonymous and Narcotics Anonymous meetings? A prospective investigation with outpatient youth.

Kelly, John F; Dow, Sarah J; Yeterian, Julie D; Myers, Mark

2011-06-01

Alcoholics Anonymous (AA) and Narcotics Anonymous (NA) have proven to be cost-effective recovery resources for adults and also appear helpful for youth. However, anecdotal concerns about adolescents' safety at meetings have dampened enthusiasm regarding youth participation. Unfortunately, little information exists to evaluate such concerns. Outpatients (N = 127; 24% female) were assessed at intake and at 3, 6, and 12 months regarding perceived safety at AA/NA, experience of negative incidents, and reasons for nonattendance/discontinuation. By 12-month follow-up, 57.5% reported some AA/NA attendance with a combined lifetime exposure of 5,340 meetings. Of these, 21.9% reported at least one negative experience, which was more common among NA than AA attendees. Overall, youth reported feeling very safe at meetings, and ratings did not differ by age or gender. Reasons for discontinuation or nonattendance were unrelated to safety or negative incidents. Weighing risks against documented benefits, these preliminary findings suggest that referral to AA/NA should not be discouraged, but, similar to adults, youth experiences at meetings should be monitored.

2018-03-01

To examine the relationships between workplace bullying, destructive leadership and team conflict, and physical health, strain, self-reported performance and intentions to quit among veterinarians in New Zealand, and how these relationships could be moderated by psychological capital and perceived organisational support. Data were collected by means of an online survey, distributed to members of the New Zealand Veterinary Association. Participation was voluntary and all responses were anonymous and confidential. Scores for the variables measured were based on responses to questions or statements with responses categorised on a linear scale. A series of regression analyses were used to assess mediation or moderation by intermediate variables on the relationships between predictor variables and dependent variables. Completed surveys were provided by 197 veterinarians, of which 32 (16.2%) had been bullied at work, i.e. they had experienced two or more negative acts at least weekly over the previous 6 months, and nine (4.6%) had experienced cyber-bullying. Mean scores for workplace bullying were higher for female than male respondents, and for non-managers than managers (p<0.01). Scores for workplace bullying were positively associated with scores for destructive leadership and team conflict, physical health, strain, and intentions to quit (p<0.001). Workplace bullying and team conflict mediated the relationship between destructive leadership and strain, physical health and intentions to quit. Perceived organisational support moderated the effects of workplace bullying on strain and self-reported job performance (p<0.05). Relatively high rates of negative behaviour were reported by veterinarians in this study, with 16% of participants meeting an established criterion for having been bullied. The negative effects of destructive leadership on strain, physical health and intentions to quit were mediated by team conflict and workplace bullying. It should be noted that the

This study had three objectives: (1) to investigate the impact of workplace incivility on job burn-out of new nursing staff, (2) to verify the partial mediating role of anxiety in the relationship between workplace incivility and job burn-out, (3) to examine the resilience moderating the relations between workplace incivility and job burn-out. A cross-sectional online survey was conducted in May 2016 in China. The survey was conducted in 54 cities across 29 provinces of China. A total of 903 participants were invited. Ultimately, 696 new nurses (<3 service years) completed valid questionnaires. The effective response rate was 77.1%. Entry criteria: voluntary participation, having less than three service years and being a registered nurse. being an irregular nurse, having more than three service years and refusing to participate in this work. An anonymous questionnaire was distributed among new nurses. The relationships and mechanism among the variables were explored using descriptive statistical analysis, Pearson's correlation coefficient and multiple linear regression analysis. The findings showed that workplace incivility was positively correlated with anxiety (r=0.371, p<0.01) and job burn-out (r=0.238, p<0.01) of new nurses. The positive relation between anxiety (β = 0.364, p<0.01) and job burn-out (β = 0.240, p<0.01) was also significant. Moreover, anxiety partially mediated (z=7.807, p<0.01) and resilience moderated (β=-0.564, p<0.01) the association between workplace incivility and job burn-out. Experience of workplace incivility by new nurses would likely generate anxiety in the victims. Further, the increased anxiety state could elevate their level of job burn-out. New nurses with high levels of resilience could buffer the negative influence of workplace incivility by using a positive coping style. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Employment-based reinforcement interventions have been used to promote abstinence from drugs among chronically unemployed injection drug users. The current study used an employment-based reinforcement intervention to promote opioid and cocaine abstinence among opioid and/or cocaine-dependent, HIV-positive participants who had recently completed a brief inpatient detoxification. Participants (n = 46) were randomly assigned to an abstinence and work group that was required to provide negative urine samples in order to enter the workplace and to earn incentives for work (n = 16), a work-only group that was permitted to enter the workplace and to earn incentives independent of drug use (n = 15), and a no-voucher control group that did not receive any incentives for working (n = 15) over a 26-week period. The primary outcome was urinalysis-confirmed opioid, cocaine, and combined opioid/cocaine abstinence. Participants were 78% male and 89% African American. Results showed no significant between-groups differences in urinalysis-verified drug abstinence or HIV risk behaviors during the 6-month intervention. The work-only group had significantly greater workplace attendance, and worked more minutes per day when compared to the no-voucher group. Several features of the study design, including the lack of an induction period, setting the threshold for entering the workplace too high by requiring immediate abstinence from several drugs, and increasing the risk of relapse by providing a brief detoxification that was not supported by any continued pharmacological intervention, likely prevented the workplace from becoming established as a reinforcer that could be used to promote drug abstinence. However, increases in workplace attendance have important implications for adult training programs.

This paper addresses the political actions of Anonymous, the principal expression of current hacker activism, arguing that hacktivism is a form of political resistance in control societies. To this end, it focuses on studying the Brazilian, hacktivist facet of the collective. In order to stress its political character, it scrutinizes the principal expressions of hacking in the literature. It describes motivations, methods and the ethics of its political actions, based on a comparative analysis of two operations carried out by Brazilian Anonymous adherents in 2012: #OpWeeksPayment and #OpGlobo. And it finishes by identifying four of its main forms of political engagement: promotion of anonymity; "evangelization;" the formation of distributed networks; and the fact that the collective carries out and facilitates several types of political actions.

Factors and facts in Hungarian HIV/AIDS epidemic, 1985-2000.

PubMed

Dömök, I

2001-01-01

In Hungary among others there were some special factors, which shaped the outcome of HIV/AIDS epidemic. (1) In the early period of pandemic the "iron curtain" delayed and limited the importation of HIV to Hungary. (2) In 1985, at the time of detection of first HIV infected persons the etiological diagnostic tools were already commercially available and laboratory facilities have been created immediately for HIV antibody tests in networks of blood banks, public health and venereological services. (3) Laboratory facilities together with introduced health regulations resulted in (a) elimination of possibility of nosocomial HIV transmission by blood, blood products and organ transplantation; (b) efficient case finding and contact tracing in population groups potentially playing a significant role in spreading of infection; (c) opportunities for voluntary HIV testing free of charge. (4) Broad scale education and information activities have been developed from the beginning by governmental and non-governmental organizations alike. (5) Parenteral drug abuse did not play a role in spreading of HIV, so far. The above factors resulted in a slowly developing moderate epidemic. The facts are as follows. By the end of 2000 altogether 879 HIV positive (666 male, 100 female and 113 anonymous) persons have been notified, 377 (344 male and 33 female) of whom showed already the characteristic features of AIDS and 229 died. 29% of registered HIV positive persons have been foreigners originating from 56 countries. The cumulative incidence rate of AIDS was 38 per million population. 73% of Hungarian HIV positive persons and 72% of patients with AIDS belonged to transmission group of men having sex with men. The age of HIV positive persons at the time of detection was between 20 and 49 years in 81% and 72% of them resided in or around Budapest.

2016-09-01

An estimated one in eight men who have sex with men (MSM) in London lives with HIV, of which 16% are undiagnosed. It is a public health priority to minimise time spent undiagnosed and reduce morbidity, mortality and onward HIV transmission. 'Dean Street at Home' provided an online HIV risk self-assessment and postal home HIV sampling service aimed at hard-to-reach, high-risk MSM. This 2-year service evaluation aims to determine the HIV risk behaviour of users, the uptake of offer of home sampling and the acceptability of the service. Users were invited to assess their HIV risk anonymously through messages or promotional banners on several gay social networking websites. Regardless of risk, they were offered a free postal HIV oral fluid or blood self-sampling kit. Reactive results were confirmed in clinic. A user survey was sent to first year respondents. 17 361 respondents completed the risk self-assessment. Of these, half had an 'identifiable risk' for HIV and a third was previously untested. 5696 test kits were returned. 121 individuals had a reactive sample; 82 (1.4% of returned samples) confirmed as new HIV diagnoses linked to care; 14 (0.25%) already knew their diagnosis; and 14 (0.25%) were false reactives. The median age at diagnosis was 38; median CD4 505 cells/µL and 20% were recent infections. 61/82 (78%) were confirmed on treatment at the time of writing. The post-test email survey revealed a high service acceptability rate. The service was the first of its kind in the UK. This evaluation provides evidence to inform the potential roll-out of further online strategies to enhance community HIV testing. Published by the BMJ Publishing Group Limited.

The effect of sympathy on discriminatory attitudes toward persons living with HIV/AIDS in Puerto Rico: a hierarchical analysis of women living in public housing.

PubMed

Norman, Lisa R; Abreu, Silkha; Candelaria, Erika; Sala, Ana

2009-02-01

As the number of persons living with HIV/AIDS (PLWHA) continues to increase in Puerto Rico, it becomes increasingly important to address the issues of stigma and other discriminatory attitudes. Therefore, the objective of the present study is to examine the attitudes toward PLWHA of a large sample of women living in public housing in Puerto Rico, including sympathy and support for PLWHA in the workplace and in school. A total of 1138 women completed a self-administered 218-item survey made up of questions that measured HIV-related knowledge, attitudes and behaviors. Levels of sympathy varied depending upon the target group, with HIV-infected drug users receiving the least sympathy. Most women reported that HIV-positive teachers should be allowed to teach and that HIV-positive children should be allowed to attend school. However, a significantly lower percentage reported that HIV-infected nurses should be allowed to continue working. Women who were more sympathetic toward PLWHA were more tolerant of PLWHA in the workplace and school, while those with inaccurate knowledge concerning HIV transmission were less tolerant. Also, those who knew a PLWHA were more tolerant. Levels of discriminatory attitudes in Puerto Rico are high and warrant both individual- and societal-level interventions.

2013-01-01

Researchers often face the problem of needing to protect the privacy of subjects while also needing to integrate data that contains personal information from diverse data sources. The advent of computational social science and the enormous amount of data about people that is being collected makes protecting the privacy of research subjects ever more important. However, strict privacy procedures can hinder the process of joining diverse sources of data that contain information about specific individual behaviors. In this paper we present a procedure to keep information about specific individuals from being “leaked” or shared in either direction between two sources of data without need of a trusted third party. To achieve this goal, we randomly assign individuals to anonymous groups before combining the anonymized information between the two sources of data. We refer to this method as the Yahtzee procedure, and show that it performs as predicted by theoretical analysis when we apply it to data from Facebook and public voter records. PMID:23441156

Researchers often face the problem of needing to protect the privacy of subjects while also needing to integrate data that contains personal information from diverse data sources. The advent of computational social science and the enormous amount of data about people that is being collected makes protecting the privacy of research subjects ever more important. However, strict privacy procedures can hinder the process of joining diverse sources of data that contain information about specific individual behaviors. In this paper we present a procedure to keep information about specific individuals from being "leaked" or shared in either direction between two sources of data without need of a trusted third party. To achieve this goal, we randomly assign individuals to anonymous groups before combining the anonymized information between the two sources of data. We refer to this method as the Yahtzee procedure, and show that it performs as predicted by theoretical analysis when we apply it to data from Facebook and public voter records.

The emergence of HIV in rural India has the potential to heighten gender inequity in a context where women already suffer significant health disparities. Recent Indian health policies provide new opportunities to identify and implement gender-equitable rural HIV services. In this review, we adapt Mosley and Chen's conceptual framework of health to outline determinants for HIV health services utilization and outcomes. Examining the framework through a gender lens, we conduct a comprehensive literature review for gender-related gaps in HIV clinical services in rural India, focusing on patient access and outcomes, provider practices, and institutional partnerships. Contextualizing findings from rural India in the broader international literature, we describe potential strategies for gender-equitable HIV services in rural India, as responses to the following three questions: (1) What gender-specific patient needs should be addressed for gender-equitable HIV testing and care? (2) What do health care providers need to deliver HIV services with gender equity? (3) How should institutions enforce and sustain gender-equitable HIV services? Data at this early stage indicate substantial gender-related differences in HIV services in rural India, reflecting prevailing gender norms. Strategies including gender-specific HIV testing and care services would directly address current gender-specific patient needs. Rural care providers urgently need training in gender sensitivity and HIV-related communication and clinical skills. To enforce and sustain gender equity, multi-sectoral institutions must establish gender-equitable medical workplaces, interdisciplinary HIV services partnerships, and oversight methods, including analysis of gender-disaggregated data. A gender-equitable approach to rural India's rapidly evolving HIV services programmes could serve as a foundation for gender equity in the overall health care system.

Young men who have sex with men (YMSM) are increasingly using mobile smartphone applications ("apps"), such as Grindr, to meet sex partners. A probability sample of 195 Grindr-using YMSM in Southern California were administered an anonymous online survey to assess patterns of and motivations for Grindr use in order to inform development and tailoring of smartphone-based HIV prevention for YMSM. The number one reason for using Grindr (29 %) was to meet "hook ups." Among those participants who used both Grindr and online dating sites, a statistically significantly greater percentage used online dating sites for "hook ups" (42 %) compared to Grindr (30 %). Seventy percent of YMSM expressed a willingness to participate in a smartphone app-based HIV prevention program. Development and testing of smartphone apps for HIV prevention delivery has the potential to engage YMSM in HIV prevention programming, which can be tailored based on use patterns and motivations for use.

2011-01-01

In order to support the increasing need to share electronic health data for research purposes, various methods have been proposed for privacy preservation including k-anonymity. Many k-anonymity models provide the same level of anoymization regardless of practical need, which may decrease the utility of the dataset for a particular research study. In this study, we explore extensions to the k-anonymity algorithm that aim to satisfy the heterogeneous needs of different researchers while preserving privacy as well as utility of the dataset. The proposed algorithm, Attribute Utility Motivated k-anonymization (AUM), involves analyzing the characteristics of attributes and utilizing them to minimize information loss during the anonymization process. Through comparison with two existing algorithms, Mondrian and Incognito, preliminary results indicate that AUM may preserve more information from original datasets thus providing higher quality results with lower distortion.

2013-01-01

Electronic medical record (EMR) systems have enabled healthcare providers to collect detailed patient information from the primary care domain. At the same time, longitudinal data from EMRs are increasingly combined with biorepositories to generate personalized clinical decision support protocols. Emerging policies encourage investigators to disseminate such data in a deidentified form for reuse and collaboration, but organizations are hesitant to do so because they fear such actions will jeopardize patient privacy. In particular, there are concerns that residual demographic and clinical features could be exploited for reidentification purposes. Various approaches have been developed to anonymize clinical data, but they neglect temporal information and are, thus, insufficient for emerging biomedical research paradigms. This paper proposes a novel approach to share patient-specific longitudinal data that offers robust privacy guarantees, while preserving data utility for many biomedical investigations. Our approach aggregates temporal and diagnostic information using heuristics inspired from sequence alignment and clustering methods. We demonstrate that the proposed approach can generate anonymized data that permit effective biomedical analysis using several patient cohorts derived from the EMR system of the Vanderbilt University Medical Center.

Work-related stress has been evaluated as one of the most important health risks in Europe. Prevention of work related stress and interventions to reduce risk factors for stress in the workplace are conducted together by the enterprise and occupational health services. The aim of the study was to examine the experiences of Finnish occupational physicians on the stress management with enterprises. From the Finnish Association of Occupational Health Physicians membership list 207 physicians responded to self-administered anonymous questionnaire. The data were analysed using SPSS 17.0. The client enterprises contacted occupational health services frequently about work-related stress. Collaboration between occupational health and enterprises was strongest in companies' own occupational health services and generally with most experienced physicians. Occupational health services and enterprises shared responsibility for managing work-related stress. Professional experience and close contact with organisation management favours successful stress management between occupational health and enterprises.

This article presents findings from a survey of programmes available for tobacco and alcohol users working in 455 of Australia's top 600 companies. Companies were twice as likely to have programmes for smokers (43%) as for problem drinkers (24%) and these programmes were more apparent in large companies. The majority of programmes for smoking were delivered within a health promotion context which included other life-style issues, such as nutrition, exercise, weight management and stress management. Although Employee Assistance Programs (EAPs) were the most commonly available type of work-place programme for excessive drinkers and other drug users, followed by Alcoholics Anonymous and local hospital clinics, only 6% had an EAP for alcohol. Only 21% of programmes for smokers and 12% for excessive alcohol users were evaluated. Around one-quarter of companies knew the costs of smoking programmes, and 9% reported costs of conducting programmes for excessive alcohol consumers.

HIV epidemics in West Africa appear far more concentrated among key populations including men who have sex with men (MSM) and female sex workers (FSW) as compared to the more generalized epidemics of Southern and Eastern Africa. Since there has been no prior quantitative assessment of HIV risk among MSM in the Gambia, this study aims to describe the burden of HIV and associations of HIV infections. A total of 207 study participants reporting anal sex with another man in the previous 12 months were accrued using snowball sampling for this cross-sectional study and were administered an anonymous structured questionnaire. Bivariate and multivariate logistic regression models were used to identify factors associated with prevalent HIV infections. HIV prevalence was 9.8% (20/205) and the highest HIV prevalence age group was among the participants who were older than 25 years with 22.9% (8/35) living with HIV. Less than 10% of participants reported always using condoms with male partners (19/201) while 33.8% (69/204) of men reported no access to condoms and 82.5% (146/177) reported no access to latex condom-compatible lubricants (CCL). Knowledge of HIV risks was low with 3.5% (7/200) knowing that receptive anal intercourse was the highest risk sexual practice and CCL were the safest to use. This study highlighted that, similar to other West Africa countries, MSM are a high risk and underserved population for HIV prevention, treatment, and care services in the Gambia. Multilateral efforts including government, service providers, and community are needed to achieve reductions in HIV incidence and eventually prevalence among MSM in the Gambia.

Prevalence and risk factors of HIV-1 and HIV-2 infection in urban and rural areas in Tamil Nadu, India.

We aim to study the factors associated with the prevalence of HIV-1 and HIV-2 infection in the urban and rural areas of Tamil Nadu, India. The population of Tamil Nadu is approximately 60 million. Between April 94 and March 95, 992 samples from 5 representative urban centres and 1071 samples from 5 representative rural centres were collected and studied. A questionnaire was administered privately and it preceded collection of each sample. Samples were screened using ELISA and antibodies to HIV-1 and HIV-2 were confirmed using Western blot. The study was anonymous and unlinked. The prevalence of HIV infection in urban and rural areas was 7.2% (95% CI=6.1 to 8.31%); HIV-1 antibodies were found in 7.4% (95% CI=5.8 to 9.2%) of urban and 7.0% (95% CI=5.6 to 8.7%) of rural population; HIV-2 antibodies were found in 0.8% of urban and 0.3% of rural population. Heterosexual transmission, more so among those with multiple partner sex, was the main mode; higher prevalence of HIV infection among divorced/single individuals both in urban (21.1%) and rural (26.1%) was found. HIV infection among housewives stood at 4.1% (urban) and 3.8% (rural). The strength of association between STDs and HIV was observed to be greater in rural subjects (OR=8.89; 95% CI=5.11 to 15.57) than in urban subjects (OR=1.9; 95% CI=1.14 to 3.18). The prevalence of condom use was found to be less than 2% in the study subjects. HIV-2 is not as widely prevalent in Tamil Nadu as HIV-1. In our study the most common risk factors for HIV infection that emerged were (a) having multiple sexual partners, and (b) history of STDs or Venereal Disease Research Laboratory (VDRL) reactivity. Mobility of individuals between urban and rural areas has furthered the dissemination of HIV infection. Low condom usage among study subjects questions the effectiveness of the existing AIDS awareness and education programme. The study indicates the importance of placing equal emphasis on HIV prevention in rural India. HIV infection

Introduction In 2010, two global networks of people living with HIV, the International Community of Women Living with HIV (ICW Global) and the Global Network of People living with HIV (GNP + ) were invited to review a draft strategic framework for the global scale up of prevention of vertical transmission (PVT) through the primary prevention of HIV and the prevention of unintended pregnancies among women living with HIV. In order to ensure recommendations were based on expressed needs of people living with HIV, GNP+ and ICW Global undertook a consultation amongst people living with HIV which highlighted both facilitators and barriers to prevention services. This commentary summarizes the results of that consultation. Discussion The consultation was comprised of an online consultation (moderated chat-forum with 36 participants from 16 countries), an anonymous online e-survey (601 respondents from 58 countries), and focus-group discussions with people living with HIV in Jamaica (27 participants). The consultation highlighted the discrepancies across regions with respect to access to essential packages of PVT services. However, the consultation participants also identified common barriers to access, including a lack of trustworthy sources of information, service providers’ attitudes, and gender-based violence. In addition, participant responses revealed common facilitators of access, including quality counselling on reproductive choices, male involvement, and decentralized services. Conclusions The consultation provided some understanding and insight into the participants’ experiences with and recommendations for PVT strategies. Participants agreed that successful, comprehensive PVT programming require greater efforts to both prevent primary HIV infection among young women and girls and, in particular, targeted efforts to ensure that women living with HIV and their partners are supported to avoid unintended pregnancies and to have safe, healthy pregnancies instead

The end of donor anonymity: how genetic testing is likely to drive anonymous gamete donation out of business.

2016-06-01

Thousands of people worldwide have been conceived using donor gametes, but not all parents tell their children of their origin. Several countries now allow donor-conceived offspring to potentially know their genetic parent if they are informed of their donor-conceived status. At the same time, personal genetic testing is a rapidly expanding field. Over 3 million people have already used direct-to-consumer genetic testing to find information about their ancestry, and many are participating in international genetic genealogy databases that will match them with relatives. The increased prevalence of these technologies poses numerous challenges to the current practice of gamete donation. (i) Whether they are donating in a country that practices anonymous donation or not, donors should be informed that their anonymity is not guaranteed, as they may be traced if their DNA, or that of a relative, is added to a database. (ii) Donor-conceived adults who have not been informed of their status may find out that they are donor-conceived. (iii) Parents using donor conception need to be fully informed that their children's DNA will identify that they are not the biological parents and they should be encouraged to disclose the use of donor gametes to their children. Together, these concerns make urgent a wide-ranging societal conversation about how to best safeguard and promote the interests of donor-conceived offspring and protect the rights of donors. Specifically, there is a need to ensure that new genetic information is communicated in a way that promotes both the safety and the privacy rights of offspring and donors alike. All parties concerned must be aware that, in 2016, donor anonymity does not exist. © The Author 2016.

Privacy Vulnerability of Published Anonymous Mobility Traces

2013-06-01

Mobility traces of people and vehicles have been collected and published to assist the design and evaluation of mobile networks, such as large-scale urban sensing networks. Although the published traces are often made anonymous in that the true identities of nodes are replaced by random identifiers, the privacy concern remains. This is because in real life, nodes are open to observations in public spaces, or they may voluntarily or inadvertently disclose partial knowledge of their whereabouts. Thus, snapshots of nodes’ location information can be learned by interested third parties, e.g., directly through chance/engineered meetings between the nodes and their observers,more » or indirectly through casual conversations or other information sources about people. In this paper, we investigate how an adversary, when equipped with a small amount of the snapshot information termed as side information, can infer an extended view of the whereabouts of a victim node appearing in an anonymous trace. Our results quantify the loss of victim nodes’ privacy as a function of the nodal mobility, the inference strategies of adversaries, and any noise that may appear in the trace or the side information. Generally, our results indicate that the privacy concern is significant in that a relatively small amount of side information is sufficient for the adversary to infer the true identity (either uniquely or with high probability) of a victim in a set of anonymous traces. For instance, an adversary is able to identify the trace of 30%-50% of the victims when she has collected 10 pieces of side information about a victim.« less

Due to their frequent use in unattended and hostile deployment environments, the security in wireless sensor networks (WSNs) has attracted much interest in the past two decades. However, it remains a challenge to design a lightweight authentication protocol for WSNs because the designers are confronted with a series of desirable security requirements, e.g., user anonymity, perfect forward secrecy, resistance to de-synchronization attack. Recently, the authors presented two authentication schemes that attempt to provide user anonymity and to resist various known attacks. Unfortunately, in this work we shall show that user anonymity of the two schemes is achieved at the price of an impractical search operation-the gateway node may search for every possible value. Besides this defect, they are also prone to smart card loss attacks and have no provision for perfect forward secrecy. As our main contribution, a lightweight anonymous authentication scheme with perfect forward secrecy is designed, and what we believe the most interesting feature is that user anonymity, perfect forward secrecy, and resistance to de-synchronization attack can be achieved at the same time. As far as we know, it is extremely difficult to meet these security features simultaneously only using the lightweight operations, such as symmetric encryption/decryption and hash functions.

Behavioral change interventions using peer group leaders are effective and widely used, but few studies have examined how being a peer group leader affects the leaders. This study describes how participants felt being a peer group leader affected their lives. This descriptive qualitative study interviewed 18 experienced peer group leaders who had conducted a multisession human immunodeficiency virus (HIV) prevention peer group intervention in rural Malawi. We used inductive content analysis and comparisons within and between cases. Three major themes were identified. All leaders said they experienced personal changes in their knowledge, attitudes, or HIV prevention behaviors. They described interacting with family, neighbors, and friends, and speaking at church or community meetings, to discuss HIV prevention issues. They increased their self-efficacy to engage others in sensitive HIV prevention issues, developed a self-identity as a change agent, and came to be recognized in their community as trustworthy advisors about HIV and acquired immunodeficiency syndrome. These three themes, taken together, form the meta-theme of psychological empowerment. Being a peer group leader empowered the leaders as change agents for HIV prevention and had impacts in the community after the intervention ended, potentially increasing the long-term effectiveness and cost effectiveness of peer group interventions. Healthcare workers and community volunteers who led HIV prevention sessions continued HIV prevention activities in the community and workplace after the program ended. Training health workers as volunteer HIV prevention leaders offers a strategy to bring HIV prevention to limited-resource settings, despite health worker shortages. © 2013 Sigma Theta Tau International.

Background Due to the rapid evolution of HIV, infections with similar genetic sequences are likely to be related by recent transmission events. Clusters of related infections can represent subpopulations with high rates of HIV transmission. Here we describe the implementation of an automated “near real-time” system using clustering analysis of routinely collected HIV resistance genotypes to monitor and characterize HIV transmission hotspots in British Columbia (BC). Methods A monitoring system was implemented on the BC Drug Treatment Database, which currently holds over 32000 anonymized HIV genotypes for nearly 9000 residents of BC living with HIV. On average, five to six new HIV genotypes are deposited in the database every day, which triggers an automated re-analysis of the entire database. Clusters of five or more individuals were extracted on the basis of short phylogenetic distances between their respective HIV sequences. Monthly reports on the growth and characteristics of clusters were generated by the system and distributed to public health officers. Findings In June 2014, the monitoring system detected the expansion of a cluster by 11 new cases over three months, including eight cases with transmitted drug resistance. This cluster generally comprised young men who have sex with men. The subsequent report precipitated an enhanced public health follow-up to ensure linkage to care and treatment initiation in the affected subpopulation. Of the nine cases associated with this follow-up, all had already been linked to care and five cases had started treatment. Subsequent to the follow-up, three additional cases started treatment and the majority of cases achieved suppressed viral loads. Over the following 12 months, 12 new cases were detected in this cluster with a marked reduction in the onward transmission of drug resistance. Interpretation Our findings demonstrate the first application of an automated phylogenetic system monitoring a clinical database to

The development of personalized medicine is tightly linked with the correct exploitation of molecular data, especially those associated with the genome sequence along with these use of genomic data there is an increasing demand to share these data for research purposes. Transition of clinical data to research is based in the anonymization of these data so the patient cannot be identified, the use of genomic data poses a great challenge because its nature of identifying data. In this work we have analyzed current methods for genome anonymization and propose a one way encryption method that may enable the process of genomic data sharing accessing only to certain regions of genomes for research purposes.

The influence of anonymous peers on prosocial behavior

Background Peer influence on students’ maladaptive behaviors has been well documented; however, the influence on positive development is less acknowledged. Purpose The purpose of this study was to examine anonymous peer influence on college students’ prosocial behavior, specifically behavior for the improvement of society (i.e., donating money or participating in social campaigns) via an experimental approach. The effects of indirect peer influence (IP) and direct peer influence (DP) on college students’ prosocial behavior were examined. Methods A total of 125 college students participated in an online survey and laboratory experiment. Self-reported helping behavior, social concern goals, and empathy were measured by the online survey. In the laboratory experiments, reading of a prosocial paragraph (IP) and confederates’ prosocial behavior (DP) were manipulated. Participation in a signature campaign and money donation for illness were observed. Furthermore, 19 participants among those who donated were asked about their reasons for participating in such prosocial behavior. Results Prosocial behavior of anonymous peers (confederates) exerts a profound influence on college students’ participation in a signature campaign and money donation, whereas the reading of a prosocial paragraph has no effect. Furthermore, no participants reported peer influence as a reason for engaging in prosocial behavior. Conclusion This finding supports and extends recent research examining the positive impacts of anonymous peers on prosocial behavior. Prosocial behavior is not only a foundational and consistent aspect of personality, as previous studies report, but is also highly malleable and unstable in response to immediate situations.

Utility-preserving transaction data anonymization with low information loss.

Loukides, Grigorios; Gkoulalas-Divanis, Aris

2012-08-01

Transaction data record various information about individuals, including their purchases and diagnoses, and are increasingly published to support large-scale and low-cost studies in domains such as marketing and medicine. However, the dissemination of transaction data may lead to privacy breaches, as it allows an attacker to link an individual's record to their identity. Approaches that anonymize data by eliminating certain values in an individual's record or by replacing them with more general values have been proposed recently, but they often produce data of limited usefulness. This is because these approaches adopt value transformation strategies that do not guarantee data utility in intended applications and objective measures that may lead to excessive data distortion. In this paper, we propose a novel approach for anonymizing data in a way that satisfies data publishers' utility requirements and incurs low information loss. To achieve this, we introduce an accurate information loss measure and an effective anonymization algorithm that explores a large part of the problem space. An extensive experimental study, using click-stream and medical data, demonstrates that our approach permits many times more accurate query answering than the state-of-the-art methods, while it is comparable to them in terms of efficiency.

Transaction data record various information about individuals, including their purchases and diagnoses, and are increasingly published to support large-scale and low-cost studies in domains such as marketing and medicine. However, the dissemination of transaction data may lead to privacy breaches, as it allows an attacker to link an individual’s record to their identity. Approaches that anonymize data by eliminating certain values in an individual’s record or by replacing them with more general values have been proposed recently, but they often produce data of limited usefulness. This is because these approaches adopt value transformation strategies that do not guarantee data utility in intended applications and objective measures that may lead to excessive data distortion. In this paper, we propose a novel approach for anonymizing data in a way that satisfies data publishers’ utility requirements and incurs low information loss. To achieve this, we introduce an accurate information loss measure and an effective anonymization algorithm that explores a large part of the problem space. An extensive experimental study, using click-stream and medical data, demonstrates that our approach permits many times more accurate query answering than the state-of-the-art methods, while it is comparable to them in terms of efficiency.

Forsythe, S; Roberts, M

AIDSCAP is undertaking a project designed to encourage Kenya's private sector to participate in HIV/AIDS prevention efforts. Part of that project involves estimating the impact of HIV/AIDS on Kenya's commercial sector. AIDSCAP and Kenyan researcher estimates are based upon financial data from a sugar estate, a transportation company, a wood processing plant, a textile factory, and a light manufacturing company, a small sample representing the diversity of industries in the country. Most are medium-sized companies with 1200-2200 employees. Preliminary results suggest that absenteeism, training costs, and HIV-related health care will cause the greatest losses to Kenyan businesses. Projections show that the HIV/AIDS epidemic could increase labor costs for some Kenyan businesses by 17% by the year 2005. Despite increasing labor costs, however, the epidemic may not cause a significant drop in profits for larger, capital-intensive Kenyan businesses. Some companies could still find their profits cut by 15-25% within the next 10 years. Study findings and implications for workplace prevention programs are discussed.

Different workplace-related strains and different workplace-related anxieties in different professions.

Similar to the spectrum of the traditional anxiety disorders, there are also different types of workplace-related anxieties. The question is whether in different professional settings different facets of workplace-related anxieties are predominant. A convenience sample of 224 inpatients (71% women) from a department of psychosomatic medicine was investigated. They were assessed with a structured diagnostic interview concerning anxiety disorders and specific workplace-related anxieties. Office workers suffer relatively most often from specific social anxiety, insufficiency, and workplace phobia. Service workers suffer predominantly from unspecific social anxiety. Health care workers are characterized by insufficiency, adjustment disorders, posttraumatic stress disorder, and workplace phobia. Persons in production and education are least often affected by workplace-related anxieties. Different types of anxiety are seen in different professional domains, parallel to workplace characteristics.

Adult film production is a legal, multibillion dollar industry in California. In response to reports of human immunodeficiency virus (HIV) transmission by an adult film worker, we sought to determine the extent of HIV infection among exposed workers and to identify means of improving worker safety. The Los Angeles County Department of Health Services initiated an outbreak investigation that included interviews of infected workers to elicit information about recent sex partners, review of the testing agency's medical records and laboratory results, molecular analysis of HIV isolates from the 4 infected workers, and a risk assessment of HIV transmission in the adult film industry. Many adult film workers participate in a monthly program of screening for HIV infection by means of polymerase chain reaction-based technology to detect HIV DNA in blood. A male performer tested negative for HIV on 12 February 2004 and 17 March 2004, then tested positive for HIV on 9 April 2004. During the period between the negative test results, he experienced a flulike illness after performing unprotected vaginal and anal intercourse for an adult film produced outside the United States by a US company. After returning to California, he performed unprotected sex acts for adult films with 13 female partners who had all tested negative for HIV in the preceding 30 days; 3 subsequently tested positive for HIV (a 23% attack rate). Contact tracing identified no reasonable sources of infection other than the male index patient. Although current testing methods may shorten the window period to diagnosis of new HIV infection, they fail to prevent occupational acquisition of HIV in this setting. A California Occupational Safety and Health Administration-approved written health and safety program that emphasizes primary prevention is needed for this industry.

The rapid scale-up of human immunodeficiency virus (HIV) testing, counselling and treatment throughout sub-Saharan Africa has raised questions about how to protect patients’ rights to consent, confidentiality, counselling and care in resource-constrained settings. The Multi-country African Testing and Counselling for HIV (MATCH) study investigated client and provider experiences with different modes of testing in sub-Saharan Africa. One component of that study was a survey of 275 HIV service providers in Burkina Faso, Kenya and Uganda that gathered quantifiable indicators and qualitative descriptions using a standardized instrument. This article presents provider perspectives on the challenges of obtaining consent, protecting confidentiality, providing counselling and helping clients manage disclosure. It also explores health workers’ fear of infection within the workplace and their reports on discrimination against HIV clients within health facilities. HIV care providers in Burkina Faso, Kenya and Uganda experienced substantial rewards from their work, including satisfaction from saving lives and gaining professional skills. They also faced serious resource constraints, including staff shortages, high workloads, lack of supplies and inadequate infrastructure, and they expressed concerns about accidental exposure. Health workers described heavy emotional demands from observing clients suffer emotional, social and health consequences of being diagnosed with HIV, and also from difficult ethical dilemmas related to clients who do not disclose their HIV status to those around them, including partners. These findings suggest that providers of HIV testing and counselling need more resources and support, including better protections against HIV exposure in the workplace. The findings also suggest that health facilities could improve care by increasing attention to consent, privacy and confidentiality and that health policy makers and ethicists need to address some

To examine utilization of the National AIDS Hotline of Trinidad and Tobago (AIDSLINE), evaluate its validity as a reliable data source for monitoring national HIV-related needs, and identify changes in caller requests between two different time periods. A total of 7 046 anonymous hotline calls in 1998-2002 (T1) and 2 338 calls in 2007 (T2) were analyzed for associations between caller characteristics and call content. A subsample of the data was also analyzed qualitatively. T1 findings were compared with HIV-related data collected by national policy-makers during that period, to evaluate the hotline's validity as a data source, and findings from T2, to reveal changes in call content over time. In T1, the hotline was well utilized for information and counseling by both the general population and those living with HIV/AIDS. Call content from T2 indicated an increase versus T1 in 1) general awareness of HIV and other sexually transmitted diseases; 2) HIV testing; and 3) knowledge of HIV symptoms and transmission. HIV-related mental health needs, and the relationship between HIV and both child sexual abuse (CSA) and intimate partner violence (IPV), were identified as emerging issues. AIDSLINE is a well-utilized tool for providing information and counseling on national HIV-related issues, and a valid, cost-effective, easily accessed information source for planners and policy-makers involved in HIV management. Over the two study periods, there was an increase in HIV awareness and testing and in requests related to mental health, CSA, and IPV, but no change in sexual behaviors.

Self-fulfillment despite barriers: volunteer work of people living with HIV.

With the decline in the morbidity and mortality associated with HIV infection, the majority of people living with HIV (PWHIV) experience a higher quality of life and longer life expectancy. Since this diagnosis no longer prevents an active lifestyle, many PWHIV are re-integrating into the workplace or are contemplating this possibility. Despite the multiple advantages associated with a return to work, research has identified barriers related to work and HIV infection. These barriers could prevent an important minority of PWHIV who wish to return to work from re-integrating into this environment. In this context, volunteering could be an alternate way to regain an active lifestyle. This research found that volunteer work allowed participants to enrich their social lives, to regain a sense of psychological well-being, and to apply their abilities to the benefit of others. However, participants are restricted by their preference to volunteer for HIV-related organizations in order to avoid social stigma and rejection.

(a,k)-Anonymous Scheme for Privacy-Preserving Data Collection in IoT-based Healthcare Services Systems.

2018-02-14

The widely use of IoT technologies in healthcare services has pushed forward medical intelligence level of services. However, it also brings potential privacy threat to the data collection. In healthcare services system, health and medical data that contains privacy information are often transmitted among networks, and such privacy information should be protected. Therefore, there is a need for privacy-preserving data collection (PPDC) scheme to protect clients (patients) data. We adopt (a,k)-anonymity model as privacy pretection scheme for data collection, and propose a novel anonymity-based PPDC method for healthcare services in this paper. The threat model is analyzed in the client-server-to-user (CS2U) model. On client-side, we utilize (a,k)-anonymity notion to generate anonymous tuples which can resist possible attack, and adopt a bottom-up clustering method to create clusters that satisfy a base privacy level of (a 1 ,k 1 )-anonymity. On server-side, we reduce the communication cost through generalization technology, and compress (a 1 ,k 1 )-anonymous data through an UPGMA-based cluster combination method to make the data meet the deeper level of privacy (a 2 ,k 2 )-anonymity (a 1  ≥ a 2 , k 2  ≥ k 1 ). Theoretical analysis and experimental results prove that our scheme is effective in privacy-preserving and data quality.

We investigate the design of anonymous voting protocols, CV-based binary-valued ballot and CV-based multi-valued ballot with continuous variables (CV) in a multi-dimensional quantum cryptosystem to ensure the security of voting procedure and data privacy. The quantum entangled states are employed in the continuous variable quantum system to carry the voting information and assist information transmission, which takes the advantage of the GHZ-like states in terms of improving the utilization of quantum states by decreasing the number of required quantum states. It provides a potential approach to achieve the efficient quantum anonymous voting with high transmission security, especially in large-scale votes.

An anonymous user authentication scheme allows a user, who wants to access a remote application server, to achieve mutual authentication and session key establishment with the server in an anonymous manner. To enhance the security of such authentication schemes, recent researches combined user's biometrics with a password. However, these authentication schemes are designed for single server environment. So when a user wants to access different application servers, the user has to register many times. To solve this problem, Chuang and Chen proposed an anonymous multiserver authenticated key agreement scheme using smart cards together with passwords and biometrics. Chuang and Chen claimed that their scheme not only supports multiple servers but also achieves various security requirements. However, we show that this scheme is vulnerable to a masquerade attack, a smart card attack, a user impersonation attack, and a DoS attack and does not achieve perfect forward secrecy. We also propose a security enhanced anonymous multiserver authenticated key agreement scheme which addresses all the weaknesses identified in Chuang and Chen's scheme.

Explicit patient consent requirements in privacy laws can have a negative impact on health research, leading to selection bias and reduced recruitment. Often legislative requirements to obtain consent are waived if the information collected or disclosed is de-identified. The authors developed and empirically evaluated a new globally optimal de-identification algorithm that satisfies the k-anonymity criterion and that is suitable for health datasets. Authors compared OLA (Optimal Lattice Anonymization) empirically to three existing k-anonymity algorithms, Datafly, Samarati, and Incognito, on six public, hospital, and registry datasets for different values of k and suppression limits. Measurement Three information loss metrics were used for the comparison: precision, discernability metric, and non-uniform entropy. Each algorithm's performance speed was also evaluated. The Datafly and Samarati algorithms had higher information loss than OLA and Incognito; OLA was consistently faster than Incognito in finding the globally optimal de-identification solution. For the de-identification of health datasets, OLA is an improvement on existing k-anonymity algorithms in terms of information loss and performance.

To understand the willingness to pay for HIV antibody saliva rapid test and its influential factors among people seeking counsel and HIV test, STD clinic patients, university students, migrant people, female sex workers (FSWs), men who have sex with men (MSM) and injecting drug users (IDUs). An anonymous questionnaire survey was conducted among 511 subjects in the 7 groups selected by different sampling methods, and 509 valid questionnaires were collected. The majority of subjects were males (54.8%) and aged 20-29 years (41.5%). Among the subjects, 60.3% had education level of high school or above, 55.4% were unmarried, 37.3% were unemployed, 73.3% had monthly expenditure <2 000 Yuan RMB, 44.2% had received HIV test, 28.3% knew HIV saliva test, 21.0% were willing to receive HIV saliva test, 2.0% had received HIV saliva test, only 1.0% had bought HIV test kit for self-test, and 84.1% were willing to pay for HIV antibody saliva rapid test. Univariate logistic regression analysis indicated that subject group, age, education level, employment status, monthly expenditure level, HIV test experience and willingness to receive HIV saliva test were correlated statistically with willingness to pay for HIV antibody saliva rapid test. Multivariate logistic regression analysis showed that subject group and monthly expenditure level were statistically correlated with willingness to pay for HIV antibody saliva rapid test. The willingness to pay for HIV antibody saliva rapid test and acceptable price of HIV antibody saliva rapid test varied in different areas and populations. Different populations may have different willingness to pay for HIV antibody saliva rapid test;the affordability of the test could influence the willingness to pay for the test.

Commun Nonlinear Sci Simulat 2011;16(4):1986-92]. Niu-Wang's protocol not only achieves session key agreement between a server and a user, but also allows the user to anonymously interact with the server. Nevertheless, this paper points out that Niu-Wang's protocol has the following efficiency and security problems: (1) The protocol has computational efficiency problem when a trusted third party decrypts the user sending message. (2) The protocol is vulnerable to Denial of Service (DoS) attack based on illegal message modification by an attacker.

As a significant part of the Internet of Things (IoT), Wireless Body Area Network (WBAN) has attract much attention in this years. In WBANs, sensors placed in or around the human body collect the sensitive data of the body and transmit it through an open wireless channel in which the messages may be intercepted, modified, etc. Recently, Wang et al. presented a new anonymous authentication scheme for WBANs and claimed that their scheme can solve the security problems in the previous schemes. Unfortunately, we demonstrate that their scheme cannot withstand impersonation attack. Either an adversary or a malicious legal client could impersonate another legal client to the application provider. In this paper, we give the detailed weakness analysis of Wang et al.'s scheme at first. Then we present a novel anonymous authentication scheme for WBANs and prove that it's secure under a random oracle model. At last, we demonstrate that our presented anonymous authentication scheme for WBANs is more suitable for practical application than Wang et al.'s scheme due to better security and performance. Compared with Wang et al.'s scheme, the computation cost of our scheme in WBANs has reduced by about 31.58%.

More security concerns and complicated requirements arise in wireless sensor networks than in wired networks, due to the vulnerability caused by their openness. To address this vulnerability, anonymous authentication is an essential security mechanism for preserving privacy and providing security. Over recent years, various anonymous authentication schemes have been proposed. Most of them reveal both strengths and weaknesses in terms of security and efficiency. Recently, Farash et al. proposed a lightweight anonymous authentication scheme in ubiquitous networks, which remedies the security faults of previous schemes. However, their scheme still suffers from certain weaknesses. In this paper, we prove that Farash et al.'s scheme fails to provide anonymity, authentication, or password replacement. In addition, we propose an enhanced scheme that provides efficiency, as well as anonymity and security. Considering the limited capability of sensor nodes, we utilize only low-cost functions, such as one-way hash functions and bit-wise exclusive-OR operations. The security and lightness of the proposed scheme mean that it can be applied to roaming service in localized domains of wireless sensor networks, to provide anonymous authentication of sensor nodes.

Patients and clinicians alike view anonymous testing as a potential way to avoid perceived risks of genetic testing such as insurance and employment discrimination and the potential loss of privacy. To assess their experience with and attitudes towards anonymous testing for BRCA1/2, genetic counselors were invited to complete an internet-based survey via the NSGC Familial Cancer Risk Counseling Special Interest Group (FCRC-SIG) listerv. A majority of the 115 respondents (70%) had received requests from patients for anonymous BRCA1/2 testing at some point in their careers and 43% complied with this request. Most counselors, however, encountered such requests infrequently, 1-5 times per year. Although genetic counselors do not generally encourage anonymous testing and over a third of respondents feel it should never be offered, a substantial subset support its use under specific circumstances. In general, a strong consensus exists among counselors that anonymous testing should not be offered routinely. In light of the current legislative landscape, it is of note that a substantial proportion of respondents (42.7%) cited the threat of life insurance discrimination as a reason for pursuing AT, and fewer cited health insurance (30.0%) or employment discrimination (29.1%) as justifications. Since there exists no federal legislative protections against discrimination by life insurance companies, it makes sense that genetic counselors were more responsive to this issue as opposed to the threat of discrimination in health insurance and employment.

Because the nature of their work seafarers spend long periods of time away from their families and therefore represent a group at risk for sexually transmitted diseases, including HIV infection. This paper reports the results of a survey to evaluate awareness and knowledge of the risk of HIV infection among seafarers. Risky behaviours for HIV transmission were also assessed. The survey was conducted using anonymous questionnaires on 197 workers of 9 vessels and 26 office employees of an Italian shipping company (FINAVAL S.p.A., Rome). The respondents considered HIV/AIDS as one of the diseases with a high risk of transmission. Most respondents had a good general knowledge of HIV/AIDS and on the ways of its transmission. However, there is still lack of knowledge on the basics of this disease. On the other hand, in spite of knowledge and awareness about the risks of the disease, only 56.35% of the interviewed crewmembers used protection in sexual intercourse with occasional partners. Compared to data available in literature, the percentage of self-protecting people is increasing, but the number of seafarers exposing themselves to risky behaviours is still high. As expected, condoms are used with regular partners with lower frequency compared to occasional intercourse. The results of this survey indicate that adequate prevention campaigns and major attention paid to seafarers health is useful for stimulating responsible conduct for the prevention of infectious diseases, including HIV infection. Nevertheless, it is still necessary to increase information about the risk of sexually transmitted diseases and how to reduce it.

The number of HIV cases in Taiwan exceeded 30,000 in 2016. Per the UNAIDS 90-90-90 target, 81% of people living with HIV should receive medication. However, numerous previous studies focused on adherence rather than the initial healthcare seeking intention if diagnosed with HIV (HIV HSI). Based on the Theory of Planned Behavior (TPB), anonymous online survey data were collected from December 2016 through February 2017 from 2709 young MSM (YMSM) ages 15-39. Multivariate logistic regression found the significant factors and strengths of associations with HIV HSI varied by their HIV voluntary counseling and testing (VCT) experience. YMSM without VCT experience perceiving high support from salient others (AOR = 1.28) and high control under facilitating conditions (AOR = 2.73) had higher HIV HSI. YMSM with VCT experience perceiving high control under facilitating (AOR = 1.79) and constraining (AOR = 1.54) conditions had higher HIV HSI. Regardless of VCT experience, YMSM with positive attitudes toward positive healthcare seeking outcomes (AOR = 3.72-3.95) had highest HIV HSI, highlighting the importance of increasing positive outcome expectations in YMSM.

Collaboration and data sharing have become core elements of biomedical research. Especially when sensitive data from distributed sources are linked, privacy threats have to be considered. Statistical disclosure control allows the protection of sensitive data by introducing fuzziness. Reduction of data quality, however, needs to be balanced against gains in protection. Therefore, tools are needed which provide a good overview of the anonymization process to those responsible for data sharing. These tools require graphical interfaces and the use of intuitive and replicable methods. In addition, extensive testing, documentation and openness to reviews by the community are important. Existing publicly available software is limited in functionality, and often active support is lacking. We present ARX, an anonymization tool that i) implements a wide variety of privacy methods in a highly efficient manner, ii) provides an intuitive cross-platform graphical interface, iii) offers a programming interface for integration into other software systems, and iv) is well documented and actively supported.

Workplace bullying can not only cost thousands of dollars to replace an affected nurse, but also have detrimental economic effects on health care organizations. Occupational health nurses can provide leadership in preventing or eliminating workplace bullying. This pilot study determined that attendance at a cognitive rehearsal program decreased workplace bullying. The study used an Internet-based survey administered 6 months after nurses completed the 2-hour cognitive rehearsal program. Half of the nurses reported witnessing bullying behaviors since attending the program; 70% of the nurses reported changing their own behaviors following the course; and 40% of the nurses reported a decrease in bullying behaviors during the past 6 months. Although 70% of the nurses believed they could intervene in bullying situations, only 16% reported they responded to bullying at the time of occurrence. This study illuminates the need to continue searching for other effective methods to prevent and manage workplace bullying. Copyright 2013, SLACK Incorporated.

Towards Linking Anonymous Authorship in Casual Sexual Encounter Ads

Fries, Jason A.; Segre, Alberto M.; Polgreen, Philip M.

2013-01-01

Objective This paper constructs an authorship-linked collection or corpus of anonymous, sex-seeking ads found on the classifieds website Craigslist. This corpus is then used to validate an authorship attribution approach based on identifying near duplicate text in ad clusters, providing insight into how often anonymous individuals post sex-seeking ads and where they meet for encounters. Introduction The increasing use of the Internet to arrange sexual encounters presents challenges to public health agencies formulating STD interventions, particularly in the context of anonymous encounters. These encounters complicate or break traditional interventions. In previous work [1], we examined a corpus of anonymous personal ads seeking sexual encounters from the classifieds website Craigslist and presented a way of linking multiple ads posted across time to a single author. The key observation of our approach is that some ads are simply reposts of older ads, often updated with only minor textual changes. Under the presumption that these ads, when not spam, originate from the same author, we can use efficient near-duplicate detection techniques to cluster ads within some threshold similarity. Linking ads in this way allows us to preserve the anonymity of authors while still extracting useful information on the frequency with which authors post ads, as well as the geographic regions in which they seek encounters. While this process detects many clusters, the lack of a true corpus of authorship-linked ads makes it difficult to validate and tune the parameters of our system. Fortunately, many ad authors provide an obfuscated telephone number in ad text (e.g., 867–5309 becomes 8sixseven5three oh nine) to bypass Craigslist filters, which prohibit including phone numbers in personal ads. By matching phone numbers of this type across all ads, we can create a corpus of ad clusters known to be written by a single author. This authorship corpus can then be used to evaluate and tune

Behavioral risk was determined on the basis of responses to cross-sectional community interviews. HIV incidence was assessed through application of an enzyme-linked immunoassay testing strategy. Results. Use of HAART among MSM living with AIDS increased from 4% in 1995 to 54% in 1999. The percentage of MSM who reported both unprotected anal intercourse and multiple sexual partners increased from 24% in 1994 to 45% in 1999. The annual HIV incidence rate increased from 2.1% in 1996 to 4.2% in 1999 among MSM who sought anonymous HIV testing, and the rate was high (5.3%) but stable in a blinded survey of MSM seeking sexually transmitted disease services. Conclusions. Any decrease in per contact risk of HIV transmission due to HAART use appears to have been counterbalanced or overwhelmed by increases in the number of unsafe sexual episodes.

Confidentiality, anonymity and amnesty for midwives in distress seeking online support - Ethical?

Midwife health is intrinsically linked to the quality of safe patient care. To ensure safe patient care, there is a need to deliver emotional support to midwives. One option that midwives may turn to may be a confidential online intervention, instead of localised, face-to-face support. Following the Realist And MEta-narrative Evidence Syntheses: Evolving Standards publication standards, this realist synthesis approach explores the ethical considerations in permitting confidentiality, anonymity and amnesty in online interventions to support midwives in work-related psychological distress. An iterative search methodology was used to select nine papers for review. To assimilate information, papers were examined for ideas relating to ethical dimensions of online interventions to support midwives in work-related psychological distress. This review takes a narrative approach. Online interventions can support the development of insight, help seeking and open discussion. Additionally, Internet support groups can become morally persuasive in nature. Anonymity and confidentiality are both effective and therapeutic features of online interventions when used in collaboration with effective online moderation. Yet, ethical dilemmas remain where users cannot be identified. Confidentiality and anonymity remain key components of successful online interventions. However, sanctioning the corollary component of amnesty may provoke moral discomfort for those seeking immediate accountability. For others, amnesty is seen as essential for open disclosure and help seeking. Ultimately, the needs of midwives must be balanced with the requirement to protect the public and the professional reputation of midwifery. In supporting midwives online, the principles of anonymity, confidentiality and amnesty may evoke some resistance on ethical grounds. However, without offering identity protection, it may not be possible to create effective online support services for midwives. The authors of this

In France, since the approval of the first bioethics laws in 1994, the principle of the anonymity of sperm donors has prevailed. This choice is regularly challenged, namely by children who have been conceived under these conditions and have now reached adulthood. In this paper, we will briefly describe the reasons that led practitioners of assisted reproduction to endorse the anonymity principle in 1994. Secondly, we will elaborate on the reasons why this principle is becoming so controversial today. Finally, we shall examine two possible outcomes of the debate, highlighting their respective legitimacy as well as their consequences, as far as the rights of children, the notion of the family, and medical practice are concerned.

Workplaces are one of the most important regular meeting places in society. The aim of this study was to use simulation experiments to examine the impact of different workplace cultures on influenza dissemination during pandemics. The impact is investigated by experiments with defined social-mixing patterns at workplaces using semi-virtual models based on authentic sociodemographic and geographical data from a North European community (population 136 000). A simulated pandemic outbreak was found to affect 33% of the total population in the community with the reference academic-creative workplace culture; virus transmission at the workplace accounted for 10·6% of the cases. A model with a prevailing industrial-administrative workplace culture generated 11% lower incidence than the reference model, while the model with a self-employed workplace culture (also corresponding to a hypothetical scenario with all workplaces closed) produced 20% fewer cases. The model representing an academic-creative workplace culture with restricted workplace interaction generated 12% lower cumulative incidence compared to the reference model. The results display important theoretical associations between workplace social-mixing cultures and community-level incidence rates during influenza pandemics. Social interaction patterns at workplaces should be taken into consideration when analysing virus transmission patterns during influenza pandemics.

To determine HIV prevalence in the South African population and to investigate risk factors for HIV. A national sample of 10 197 households was selected. One child (aged 2 - 14 years), one youth (15 - 24 years) and one adult (25 years and older) were randomly selected from each household. Consenting respondents were interviewed about their socio-demographic characteristics and asked to give an oral mucosal transudate sample to test anonymously for HIV. Differential response rates were compared using unweighted data. The Orasure HIV-1 device in combination with the Vironostika HIV UNI-Form II plus O enzyme-linked immunosorbent assay kits were used to collect oral fluid specimens for HIV testing. HIV prevalence within subgroups was compared using Rao and Scott's adjusted chi-square. Relative risk was calculated using Poisson regression. All analysis was on the weighted data. Of the 10 197 households selected, 7 249 (71.1%) were included in the study. Of the 13 518 individuals selected, 9 963 (73.7%) were interviewed. Of these, 8 428 (62.3%) agreed to HIV testing and had valid results. HIV prevalence in the general population was 11.4% (12.8% in females and 9.5% in males). Blacks had the highest prevalence (12.9%), compared with whites (6.2%), coloureds (6.1%) and Indians (1.6%). Informal settlements in urban areas had the highest HIV prevalence (21.6%). The findings of this study are consistent with South African Department of Health estimates based on the 2002 antenatal survey. The Nelson Mandela/Human Sciences Research Council survey included all race, sex and age groups. It is therefore the most reliable and valid source of information on the extent and distribution of the HIV epidemic in South Africa.

A new experimentally feasible anonymous survey protocol with authentication using Greenberger-Horne-Zeilinger (GHZ) entangled states is proposed. In this protocol, a chief executive officer (CEO) of a firm or company is trying to find out the effect of a possible action. In order to prepare a fair voting, the CEO would like to make an anonymous survey and is also interested in the total action for the whole company and he doesn't want to have a partial estimate for each department. In our proposal, there are two voters, Alice and Bob, voting on a question with a response of either "yes" or "no" and a tallyman, whose responsibility is to determine whether they have cast the same vote or not. In the proposed protocol the total response of the voters is calculated without revealing the actual votes of the voters.

2003-01-01

Bathhouses are important venues for providing HIV counseling and testing to high-risk men who have sex with men (MSM), yet relatively few bathhouses routinely provide this service, and few data are available to guide program design. We examine numerous logistic considerations that had been identified in the HIV Alternative Testing Strategies study and that influenced the initiation, effectiveness, and maintenance of HIV testing programs in bathhouses for MSM. Key programmatic considerations in the design of a bathhouse HIV counseling and testing program included building alliances with community agencies, hiring and training staff, developing techniques for offering testing, and providing options for counseling, testing, and disclosure of results. The design included ways to provide client support and follow-up for partner notification and treatment counseling and to maintain relationships with bathhouse management for support of prevention activities. Early detection of HIV infection and HIV prevention can be achieved for some high-risk MSM through an accessible and acceptable HIV counseling and testing program in bathhouses. Keys to success include establishing community prevention collaborations between bathhouse personnel and testing agencies, ensuring that testing staff are supported in their work, and offering anonymous rapid HIV testing. Use of FDA approved, new rapid tests that do not require venipuncture, centrifugation, or laboratory oversight will further decrease barriers to testing and facilitate implementation of bathhouse testing programs in other communities.

The cost of quality: Implementing generalization and suppression for anonymizing biomedical data with minimal information loss.

PubMed

Kohlmayer, Florian; Prasser, Fabian; Kuhn, Klaus A

2015-12-01

With the ARX data anonymization tool structured biomedical data can be de-identified using syntactic privacy models, such as k-anonymity. Data is transformed with two methods: (a) generalization of attribute values, followed by (b) suppression of data records. The former method results in data that is well suited for analyses by epidemiologists, while the latter method significantly reduces loss of information. Our tool uses an optimal anonymization algorithm that maximizes output utility according to a given measure. To achieve scalability, existing optimal anonymization algorithms exclude parts of the search space by predicting the outcome of data transformations regarding privacy and utility without explicitly applying them to the input dataset. These optimizations cannot be used if data is transformed with generalization and suppression. As optimal data utility and scalability are important for anonymizing biomedical data, we had to develop a novel method. In this article, we first confirm experimentally that combining generalization with suppression significantly increases data utility. Next, we proof that, within this coding model, the outcome of data transformations regarding privacy and utility cannot be predicted. As a consequence, existing algorithms fail to deliver optimal data utility. We confirm this finding experimentally. The limitation of previous work can be overcome at the cost of increased computational complexity. However, scalability is important for anonymizing data with user feedback. Consequently, we identify properties of datasets that may be predicted in our context and propose a novel and efficient algorithm. Finally, we evaluate our solution with multiple datasets and privacy models. This work presents the first thorough investigation of which properties of datasets can be predicted when data is anonymized with generalization and suppression. Our novel approach adopts existing optimization strategies to our context and combines different

Background To determine the prevalence of HIV and hepatitis C virus (HCV) infections and examine risk factors for these infections among inmates in Quebec provincial prisons. Methods Anonymous cross-sectional data were collected from January to June 2003 for men (n = 1357) and women (n = 250) who agreed to participate in the study and who completed a self-administrated questionnaire and provided saliva samples. Results The prevalence of HIV infection was 2.3% among the male participants and 8.8% among the female participants. The corresponding prevalence of HCV infection was 16.6% and 29.2%, respectively. The most important risk factor was injection drug use. The prevalence of HIV infection was 7.2% among the male injection drug users and 0.5% among the male non-users. Among the women, the rate was 20.6% among the injection drug users, whereas none of the non-users was HIV positive. The prevalence of HCV infection was 53.3% among the male injection drug users and 2.6% among the male non-users; the corresponding values among the women were 63.6% and 3.5%. Interpretation HIV and HCV infections constitute an important public health problem in prison, where the prevalence is affected mainly by a high percentage of injection drug use among inmates.

2014-03-01

This cross-sectional European study assessed self-reported HIV-related discrimination and its associated factors in health care settings. Socio-demographics, health status, support needs relating to sexual and reproductive health (SRH), and self-reported HIV-related discrimination were measured using an anonymous survey in a sample of 1549 people living with HIV from 14 countries. Thirty-two per cent of the participants had experienced HIV-related discrimination during the previous 3 years; almost half of them felt discriminated against by health care providers. For this type of discrimination, logistic regression analysis revealed significant associations with not being a migrant (OR: 2.0; IC 1.0-3.7; p<0.05), having been forced into sexual activities (OR: 1.6; IC 1.2-2.2; p<0.001), reporting lack of time to discuss SRH during service provision (OR: 1.7; IC 1.0-2.7; p<0.05), and insufficient openness among service providers to discuss SRH (OR: 2.0; IC 1.1-3.4; p<0.05). Other significant associations related to unmet support needs on safer sex practices (OR: 1.8; IC 1.0-3.2; p<0.05), partner communication about sexuality (OR: 2.0; IC 1.1-3.4; p<0.05), and prevention of sexually transmitted infections (OR: 1.7; IC 1.0-3.0; p<0.05). Female gender had a protective effect (OR: 0.2; IC 0.0-0.9; p<0.05). Being denied the opportunity to discuss SRH may translate in feelings of discrimination. Improving health care providers' communication skills, and fostering openness about SRH topics in HIV care could contribute to destigmatization of PLHIV.

An Anonymous Credit Card System

NASA Astrophysics Data System (ADS)

Androulaki, Elli; Bellovin, Steven

Credit cards have many important benefits; however, these same benefits often carry with them many privacy concerns. In particular, the need for users to be able to monitor their own transactions, as well as bank’s need to justify its payment requests from cardholders, entitle the latter to maintain a detailed log of all transactions its credit card customers were involved in. A bank can thus build a profile of each cardholder even without the latter’s consent. In this paper, we present a practical and accountable anonymous credit system based on ecash, with a privacy preserving mechanism for error correction and expense-reporting.

The study investigated associations between workplace bullying and post-traumatic stress symptoms as compared to and controlled for associations between the latter and other psychosocial stress factors at work and in everyday life. The study employed a representative sample of Lithuanian family physicians, hence investigated a particularly resourceful occupational group in a geographical region earlier found to have a high risk context for exposure to bullying at work. With a response rate of 89.2%, a total of 323 family physicians filled in an anonymous questionnaire on workplace bullying, post-traumatic symptomatology (IES-R), other psychosocial stressors at work and in everyday life, personal health resources (sense of coherence), behavioral characteristics and demographic variables. The statistical software SPSS 14.0, Windows was used in the analysis. Associations were tested using a multivariate logistic regression analysis. A high prevalence of bullying was found among family physicians in Lithuania, with 13% of them experiencing severe workplace bullying and 17.3% experiencing more occasional incidents of bullying. The prevalence of post-traumatic stress symptoms was also high with 15.8% scoring above the standardized cut-off thresholds for post-traumatic stress disorder. The odds ratio (OR) of severe bullying for post-traumatic stress after adjustment for age and gender was 8.05 (95% confidence intervals (CI): 3.80-17.04). In the fully adjusted model it increased to 13.88 (95% CI: 4.68-41.13) indicating cumulative effects of all the investigated stressors. Workplace bullying is particularly prevalent among Lithuanian family physicians, as are the symptoms of post-traumatic distress. Strong associations between post-traumatic stress and exposure to severe bullying indicate that bullying is a significant source of mental health.

There were modest improvements in clinical practices, workplace policies and quality assurance in South Africa (pre-post) (clinical practices of self-pre 0.67 (95 % CI, 0.62, 0.72) versus post 0.78 (95 % CI, 0.73-0.82), p = 0.002; workplace policies-pre 0.82 (95 % CI, 0.70, 0.85) versus post 0.87 (95 % CI, 0.84, 0.90), p = 0.001; quality assurance-pre 0.72 (95 % CI, 0.67, 0.77) versus post 0.84 (95 % CI, 0.80, 0.88)). There were statistically significant improvements in scores for nurses stigmatising patients (Jamaica reports of not stigmatising-pre-post intervention 33.9 versus 62.4 %, pre-post control 54.7 versus 64.4 %, p = 0.002-and Kenya pre-post intervention 35 versus 51.6 %, pre-post control 34.2 versus 47.8 %, p = 0.006) and for nurses being stigmatised (Kenya reports of no stigmatisation-pre-post intervention 23 versus 37.3 %, pre-post control 15.4 versus 27 %, p = 0.004). Multivariate results for Kenya and Jamaica were non-significant. Twelve hubs were established; 11 were active at follow-up. Hub members (n = 34) reported significant improvements in their capacity to address care gaps. Leadership hubs, comprising nurses and other stakeholders committed to change and provided with capacity building can collectively identify issues and act on strategies that may improve practice and policy. Overall, hubs did not provide the necessary force to improve the uptake of evidence-informed HIV care in their districts. If hubs are to succeed, they must be integrated within district health authorities and become part of formal, legal organisations that can regularise and sustain them.

Workplace phobia, workplace problems, and work ability among primary care patients with chronic mental disorders.

Work-related anxieties are frequent and have a negative effect on the occupational performance of patients and absence due to sickness. Most important is workplace phobia, that is, panic when approaching or even thinking of the workplace. This study is the first to estimate the prevalence of workplace phobia among primary care patients suffering from chronic mental disorders and to describe which illness-related or workplace-specific context factors are associated with workplace phobia. A convenience sample of 288 primary care patients with chronic mental disorders (70% women) seen by 40 primary care clinicians in Germany were assessed using a standardized diagnostic interview about mental disorders and workplace problems. Workplace phobia was assessed by the Workplace Phobia Scale and a structured Diagnostic and Statical Manual of Mental Disorders-based diagnostic interview. In addition, capacity and participation restrictions, illness severity, and sick leave were assessed. Workplace phobia was found in 10% of patients with chronic mental disorders, that is, approximately about 3% of all general practice patients. Patients with workplace phobia had longer durations of sick leave than patients without workplace phobia and were impaired to a higher degree in work-relevant capacities. They also had a higher degree of restrictions in participation in other areas of life. Workplace phobia seems to be a frequent problem in primary care. It may behoove primary care clinicians to consider workplace-related anxiety, including phobia, particularly when patients ask for a work excuse for nonspecific somatic complaints. © Copyright 2014 by the American Board of Family Medicine.

Practice guidelines aim to improve the standard of care for people living with HIV/AIDS. Successfully implementing guidelines requires tailoring them to populations served and to social and organizational influences on care. To examine dimensions of context, which nurses and midwives described as having a significant impact on their care of patients living with HIV/AIDS in Kenya, Uganda, South Africa, and Jamaica and to determine whether HIV/AIDS guidelines include adaptations congruent with these dimensions of context. Two sets of data were used. The first came from a qualitative study. In-depth interviews were conducted with purposively selected nurses, midwives, and nurse managers from 21 districts in four study countries. A coding framework was iteratively developed and themes inductively identified. Context dimensions were derived from these themes. A second data set of published guidelines for HIV/AIDS care was then assembled. Guidelines were identified through Google and PubMed searches. Using a deductive integrative analysis approach, text related to context dimensions was extracted from guidelines and categorized into problem and strategy statements. Ninety-six individuals participated in qualitative interviews. Four discrete dimensions of context were identified: health workforce adequacy, workplace exposure risk, workplace consequences for nurses living with HIV/AIDS, and the intersection of work and family life. Guidelines most often acknowledged health human resource constraints and presented mitigation strategies to offset them, and least often discussed workplace consequences and the intersections of family and work life. Guidelines should more consistently acknowledge diverse implementation contexts, propose how recommendations can be adapted to these realities, and suggest what role frontline healthcare providers have in realizing the structural changes necessary for healthier work environments and better patient care.

The rapid scale-up of human immunodeficiency virus (HIV) testing, counselling and treatment throughout sub-Saharan Africa has raised questions about how to protect patients' rights to consent, confidentiality, counselling and care in resource-constrained settings. The Multi-country African Testing and Counselling for HIV (MATCH) study investigated client and provider experiences with different modes of testing in sub-Saharan Africa. One component of that study was a survey of 275 HIV service providers in Burkina Faso, Kenya and Uganda that gathered quantifiable indicators and qualitative descriptions using a standardized instrument. This article presents provider perspectives on the challenges of obtaining consent, protecting confidentiality, providing counselling and helping clients manage disclosure. It also explores health workers' fear of infection within the workplace and their reports on discrimination against HIV clients within health facilities. HIV care providers in Burkina Faso, Kenya and Uganda experienced substantial rewards from their work, including satisfaction from saving lives and gaining professional skills. They also faced serious resource constraints, including staff shortages, high workloads, lack of supplies and inadequate infrastructure, and they expressed concerns about accidental exposure. Health workers described heavy emotional demands from observing clients suffer emotional, social and health consequences of being diagnosed with HIV, and also from difficult ethical dilemmas related to clients who do not disclose their HIV status to those around them, including partners. These findings suggest that providers of HIV testing and counselling need more resources and support, including better protections against HIV exposure in the workplace. The findings also suggest that health facilities could improve care by increasing attention to consent, privacy and confidentiality and that health policy makers and ethicists need to address some

To document knowledge, attitudes and practices of voluntary HIV counselling and testing (VCT) among rural migrants in central China. A cross-sectional study with face-to-face anonymous questionnaire interviews was conducted using a structured questionnaire. Among 1280 participants, 87.9% reported having had sexual intercourse during their lifetime, with 69% of singles reporting having had sexual intercourse and 49.1% having had sex in the past month. Only 21% always used condoms, 84.4% knew HIV infection was diagnosed through blood testing, 56.6% had heard of VCT, but only 3.8% perceived their own risk for HIV infection. Only 43 (2.3%) had ever been tested for HIV, and none had ever been tested at a VCT site. About two-thirds (64.5%) would be willing to use VCT services upon awareness of HIV risk. A logistic regression model showed that females, those having little knowledge of HIV/AIDS, those unwilling to work with HIV-infected individuals, never having been tested for HIV and having low awareness regarding HIV risk were less willing to use VCT. The results of this study indicated that much greater efforts are needed to improve HIV/AIDS and VCT knowledge, to promote safer sex and to improve VCT acceptance among rural migrants in central China, particularly those engaging in risky behaviours.

Nonexposure Accurate Location K-Anonymity Algorithm in LBS

PubMed Central

2014-01-01

This paper tackles location privacy protection in current location-based services (LBS) where mobile users have to report their exact location information to an LBS provider in order to obtain their desired services. Location cloaking has been proposed and well studied to protect user privacy. It blurs the user's accurate coordinate and replaces it with a well-shaped cloaked region. However, to obtain such an anonymous spatial region (ASR), nearly all existent cloaking algorithms require knowing the accurate locations of all users. Therefore, location cloaking without exposing the user's accurate location to any party is urgently needed. In this paper, we present such two nonexposure accurate location cloaking algorithms. They are designed for K-anonymity, and cloaking is performed based on the identifications (IDs) of the grid areas which were reported by all the users, instead of directly on their accurate coordinates. Experimental results show that our algorithms are more secure than the existent cloaking algorithms, need not have all the users reporting their locations all the time, and can generate smaller ASR.

2017-03-04

Workplace violence committed by patients and visitors has high propensity to occur against emergency department employees. This article reports the association of worker, workplace, and community/environmental factors with violence risks. A cross-sectional research design was used with 280 employees from six emergency departments in the Midwest United States. Respondents completed the Survey of Violence Experienced by Staff and a 10-item demographic questionnaire. Data were analyzed using frequencies, percentages, Chi-square tests, and adjusted relative risks with 95% confidence intervals. Over 80% of respondents experienced at least one type of workplace violence with their current employer and approximately 40% experienced all three types. Risks for workplace violence were significantly higher for registered nurses and hospital-based emergency departments. Workplace violence can impact all employees in the emergency department regardless of worker, workplace, and community/environmental factors.

Sexual networks may place U.S. Black men who have sex with men (MSM) at increased HIV risk. Self-reported egocentric sexual network data from the prior six months were collected from 1,349 community-recruited Black MSM in HPTN 061, a multi-component HIV prevention intervention feasibility study. Sexual network composition, size, and density (extent to which members are having sex with one another) were compared by self-reported HIV serostatus and age of the men. GEE models assessed network and other factors associated with having a Black sex partner, having a partner with at least two age category difference (age difference between participant and partner of at least two age group categories), and having serodiscordant/serostatus unknown unprotected anal/vaginal intercourse (SDUI) in the last six months. Over half had exclusively Black partners in the last six months, 46% had a partner of at least two age category difference, 87% had ≤5 partners. Nearly 90% had sex partners who were also part of their social networks. Among HIV-negative men, not having anonymous/exchange/ trade partners and lower density were associated with having a Black partner; larger sexual network size and having non-primary partners were associated with having a partner with at least two age category difference; and having anonymous/exchange/ trade partners was associated with SDUI. Among HIV-positive men, not having non-primary partners was associated with having a Black partner; no sexual network characteristics were associated with having a partner with at least two age category difference and SDUI. Black MSM sexual networks were relatively small and often overlapped with the social networks. Sexual risk was associated with having non-primary partners and larger network size. Network interventions that engage the social networks of Black MSM, such as interventions utilizing peer influence, should be developed to address stable partnerships, number of partners, and serostatus disclosure.

k-anonymity is the method used for masking sensitive data which successfully solves the problem of re-linking of data with an external source and makes it difficult to re-identify the individual. Thus k-anonymity works on a set of quasi-identifiers (public sensitive attributes), whose possible availability and linking is anticipated from external dataset, and demands that the released dataset will contain at least k records for every possible quasi-identifier value. Another aspect of k is its capability of maintaining the truthfulness of the released data (unlike other existing methods). This is achieved by generalization, a primary technique in k-anonymity. Generalization consists of generalizing attribute values and substituting them with semantically consistent but less precise values. When the substituted value doesn’t preserve semantic validity the technique is called suppression which is a private case of generalization. We present a hybrid approach called compensation which is based on suppression and swapping for achieving privacy. Since swapping decreases the truthfulness of attribute values there is a tradeoff between level of swapping (information truthfulness) and suppression (information loss) incorporated in our algorithm.

Doctor Anonymous: Creating Contexts for Homosexuality as Mental Illness.

PubMed

Glass, Guy Fredrick

2018-03-01

In this essay, the author describes how he faced institutionalized homophobia during his psychiatric training, and how he later wrote a play inspired by the life of a gay psychiatrist. Despite Freud's supportive stance, homosexuality aroused the antipathy of American organized psychiatry and psychoanalysis and came to be listed as an illness in the Diagnostic and Statistical Manual (DSM). Dr. John E. Fryer outed himself as "Dr. H Anonymous" at a 1972 meeting of the American Psychiatric Association, and the next year homosexuality was removed from the DSM. The 2014 play Doctor Anonymous offers a fictionalized account of this watershed moment in the history of the gay rights movement. The author discusses his own psychotherapeutic work with gay male patients, including those who had previously been treated with conversion therapy, and explores how the play mirrors his own life experience and the experience of his patients.

Laboratory, clinical and sequence-based data were combined to assess the differential uptake of voluntary confidential HIV testing (VCT) according to risk and explore the occurrence of HIV transmission from individuals with recently acquired HIV infection, before the diagnostic opportunity. Between 1999 and 2002, nearly 30,000 anonymous tests for previously undiagnosed HIV infection were conducted among men who have sex with men (MSM) attending 15 sentinel sexually transmitted infection (STI) clinics in England, Wales and Northern Ireland. Using a serological testing algorithm, undiagnosed HIV-infected men were categorised into those with recent and non-recent infection. VCT uptake was compared between HIV-negative, recently HIV-infected and non-recently HIV-infected men. A phylogenetic analysis of HIV pol sequences from 127 recently HIV-infected MSM was conducted to identify instances in which transmission may have occurred before the diagnostic opportunity. HIV-negative MSM were more likely to receive VCT at clinic visits compared with undiagnosed HIV-infected MSM (56% (14,020/24,938) vs 31% (335/1072); p<0.001). Recently HIV-infected MSM were more likely to receive VCT compared with those with non-recent infections (42% (97/229) vs 28% (238/844); p<0.001). 22% (95/425) of undiagnosed HIV-infected MSM with STI received VCT. Phylogenetic analysis revealed at least seven transmissions may have been generated by recently HIV-infected MSM: a group that attended STI clinics soon after seroconversion. The integration of clinical, laboratory and sequence-based data reveals the need for specific targeting of the recently HIV exposed, and those with STI, for VCT. VCT promotion alone may be limited in its ability to prevent HIV transmission.

Sender anonymity in Location-based services (LBS) refers to hiding the identity of a mobile device user who sends requests to the LBS provider for services in her proximity (e.g. "find the nearest gas station etc."). The goal is to keep the requester's interest private even from attackers who (via hacking or subpoenas) gain access to the LBS…

Pregnancy in the workplace.

Women constitute a large percentage of the workforce in industrialized countries. As a result, addressing pregnancy-related health issues in the workplace is important in order to formulate appropriate strategies to promote and protect maternal and infant health. To explore issues affecting pregnant women in the workplace. A systematic literature review was conducted using Boolean combinations of the terms 'pregnant women', 'workplace' and 'employment' for publications from January 1990 to November 2010. Studies that explicitly explored pregnancy in the workplace within the UK, USA, Canada or the European Union were included. Pregnancy discrimination was found to be prevalent and represented a large portion of claims brought against employers by women. The relationship between environmental risks and exposures at work with foetal outcomes was inconclusive. In general, standard working conditions presented little hazard to infant health; however, pregnancy could significantly impact a mother's psychosocial well-being in the workplace. Core recommendations to improve maternal and infant health outcomes and improve workplace conditions for women include: (i) shifting organizational culture to support women in pregnancy; (ii) conducting early screening of occupational risk during the preconception period and (iii) monitoring manual labour conditions, including workplace environment and job duties.

To determine the epidemiology of work-related exposure to blood among interns. Interns were invited to complete anonymously a questionnaire concerning their past percutaneous and mucocutaneous exposures to blood. Chris Hani Baragwanath Hospital, Soweto, and Johannesburg Hospital, Gauteng, where HIV infection is common among patients. Ninety-eight interns (96%) were surveyed. Sixty-nine per cent of interns reported one or more percutaneous exposures to blood during the intern year, and 33% of interns recalled accidental percutaneous exposure to HIV-infected blood. Forty-five per cent recalled a mucocutaneous exposure to HIV-positive blood. Only 28 (64%) of 44 percutaneous injuries from HIV-infected patients were reported. During their student clinical training, 56% of interns had suffered a penetrating injury, and 18% recollected needlestick injuries involving HIV-infected patients. The most common mechanisms of injury included unexpected patient movement (23%), needle recapping (17%), and withdrawal of the needle (17%). Half of the injuries occurred during the first 4 months of internship. Only 22% of intern percutaneous exposures could have been avoided by following universal precautions. Intern and medical student exposure to blood is extremely common, but is markedly underreported. Strict compliance with universal precautions will not prevent the majority of exposures. Priorities should be the introduction of safer techniques and equipment, skills training and methods of reporting blood exposures.

Background. The diversification of human immunodeficiency virus (HIV) is shaped by its transmission history. We therefore used a population based province wide HIV drug resistance database in British Columbia (BC), Canada, to evaluate the impact of clinical, demographic, and behavioral factors on rates of HIV transmission. Methods. We reconstructed molecular phylogenies from 27 296 anonymized bulk HIV pol sequences representing 7747 individuals in BC—about half the estimated HIV prevalence in BC. Infections were grouped into clusters based on phylogenetic distances, as a proxy for variation in transmission rates. Rates of cluster expansion were reconstructed from estimated dates of HIV seroconversion. Results. Our criteria grouped 4431 individuals into 744 clusters largely separated with respect to risk factors, including large established clusters predominated by injection drug users and more-recently emerging clusters comprising men who have sex with men. The mean log10 viral load of an individual's phylogenetic neighborhood (composed of 5 other individuals with shortest phylogenetic distances) increased their odds of appearing in a cluster by >2-fold per log10 viruses per milliliter. Conclusions. Hotspots of ongoing HIV transmission can be characterized in near real time by the secondary analysis of HIV resistance genotypes, providing an important potential resource for targeting public health initiatives for HIV prevention.
