Introduction HIV-positive women have an increased risk of invasive cervical cancer but cytologic screening is effective in reducing incidence. Little is known about cervical screening coverage or the prevalence of abnormal cytology among HIV-positive women in Ukraine, which has the most severe HIV epidemic in Europe. Methods Poisson regression models were fitted to data from 1120 women enrolled at three sites of the Ukraine Cohort Study of HIV-infected Childbearing Women to investigate factors associated with receiving cervical screening as part of HIV care. All women had been diagnosed as HIV-positive before or during their most recent pregnancy. Prevalence of cervical abnormalities (high/low grade squamous intraepithelial lesions) among women who had been screened was estimated, and associated factors explored. Results Overall, 30% (337/1120) of women had received a cervical screening test as part of HIV care at study enrolment (median 10 months postpartum), a third (115/334) of whom had been tested >12 months previously. In adjusted analyses, women diagnosed as HIV-positive during (vs before) their most recent pregnancy were significantly less likely to have a screening test reported, on adjusting for other potential risk factors (adjusted prevalence ratio (APR) 0.62, 95% CI 0.51–0.75 p<0.01 for 1st/2nd trimester diagnosis and APR 0.42, 95% CI 0.28–0.63 p<0.01 for 3rd trimester/intrapartum diagnosis). Among those with a cervical screening result reported at any time (including follow-up), 21% (68/325) had a finding of cervical abnormality. In adjusted analyses, Herpes simplex virus 2 seropositivity and a recent diagnosis of bacterial vaginosis were associated with an increased risk of abnormal cervical cytology (APR 1.83 95% CI 1.07–3.11 and APR 3.49 95% CI 2.11–5.76 respectively). Conclusions In this high risk population, cervical screening coverage as part of HIV care was low and could be improved by an organised cervical screening programme for HIV

Neurocognitive Impairment (NCI) is one of the most common complications of HIV-infection, and has serious medical and functional consequences. However, screening for it is not routine and NCI often goes undiagnosed. Screening for NCI in HIV disease faces numerous challenges, such as limited screening tests, the need for specialized equipment and apparatuses, and highly trained personnel to administer, score and interpret screening tests. To address these challenges, we developed a novel smartphone-based screening tool, NeuroScreen , to detect HIV-related NCI that includes an easy-to-use graphical user interface with ten highly automated neuropsychological tests. To examine NeuroScreen's : 1) acceptability among patients and different potential users; 2) test construct and criterion validity; and 3) sensitivity and specificity to detect NCI. Fifty HIV+ individuals were administered a gold-standard neuropsychological test battery, designed to detect HIV-related NCI, and NeuroScreen . HIV+ test participants and eight potential provider-users of NeuroScreen were asked about its acceptability. There was a high level of acceptability of NeuroScreen by patients and potential provider-users. Moderate to high correlations between individual NeuroScreen tests and paper-and-pencil tests assessing the same cognitive domains were observed. NeuroScreen also demonstrated high sensitivity to detect NCI. NeuroScreen, a highly automated, easy-to-use smartphone-based screening test to detect NCI among HIV patients and usable by a range of healthcare personnel could help make routine screening for HIV-related NCI feasible. While NeuroScreen demonstrated robust psychometric properties and acceptability, further testing with larger and less neurocognitively impaired samples is warranted.

Cervical cancer prevention should be provided as part of primary healthcare services for HIV-infected women but conventional screening programs are difficult to implement in low-resource settings. Here, we evaluate the efficacy among HIV-infected women of a simpler, screen-and-treat strategy in which all women with a positive screening test are treated with cryotherapy. We conducted a randomized clinical trial of two screen-and-treat strategies among 6555 women in Cape Town, South Africa, among whom 956 were HIV-positive. Women were randomized to screen-and-treat utilizing either human papillomavirus DNA testing or visual inspection with acetic acid as the screening method or to a control group. Women were followed for up to 36 months after randomization with colposcopy and biopsy to determine the study endpoint of cervical intraepithelial neoplasia grade 2 or higher. In the control group, HIV-positive women had higher rates of cervical intraepithelial neoplasia grade 2 or higher detected by 36 months (14.9%) than HIV-negative women (4.6%) (P = 0.0006). Screen-and-treat utilizing human papillomavirus DNA testing significantly reduced cervical intraepithelial neoplasia grade 2 or higher through 36 months in both HIV-positive (relative risk = 0.20, 95% confidence interval 0.06-0.69) and HIV-negative women (relative risk = 0.31, 95% confidence interval 0.20-0.50). Reductions in the visual inspection with acetic acid-and-treat group were less marked. Complications of cryotherapy were mostly minor and did not differ in frequency between HIV-positive and HIV-negative women. Screen-and-treat using human papillomavirus testing is a simple and effective method to reduce high-grade cervical cancer precursors in HIV-infected women.

Although acute HIV infection contributes disproportionately to onward HIV transmission, HIV testing has not routinely included screening for acute HIV infection. To evaluate the performance of an HIV antigen/antibody (Ag/Ab) combination assay to detect acute HIV infection compared with pooled HIV RNA testing. Multisite, prospective, within-individual comparison study conducted between September 2011 and October 2013 in 7 sexually transmitted infection clinics and 5 community-based programs in New York, California, and North Carolina. Participants were 12 years or older and seeking HIV testing, without known HIV infection. All participants with a negative rapid HIV test result were screened for acute HIV infection with an HIV Ag/Ab combination assay (index test) and pooled human immunodeficiency virus 1 (HIV-1) RNA testing. HIV RNA testing was the reference standard, with positive reference standard result defined as detectable HIV-1 RNA on an individual RNA test. Number and proportion with acute HIV infections detected. Among 86,836 participants with complete test results (median age, 29 years; 75.0% men; 51.8% men who have sex with men), established HIV infection was diagnosed in 1158 participants (1.33%) and acute HIV infection was diagnosed in 168 participants (0.19%). Acute HIV infection was detected in 134 participants with HIV Ag/Ab combination testing (0.15% [95% CI, 0.13%-0.18%]; sensitivity, 79.8% [95% CI, 72.9%-85.6%]; specificity, 99.9% [95% CI, 99.9%-99.9%]; positive predictive value, 59.0% [95% CI, 52.3%-65.5%]) and in 164 participants with pooled HIV RNA testing (0.19% [95% CI, 0.16%-0.22%]; sensitivity, 97.6% [95% CI, 94.0%-99.4%]; specificity, 100% [95% CI, 100%-100%]; positive predictive value, 96.5% [95% CI, 92.5%-98.7%]; sensitivity comparison, P testing detected 82% of acute HIV infections detectable by pooled HIV RNA testing. Compared with rapid HIV testing alone, HIV Ag/Ab combination testing increased the relative HIV diagnostic yield (both

At an HIV clinic in the Limpopo province of South Africa, chart reviews revealed long delays in addressing abnormal Pap smears, difficulty in referrals, poor quality and lost results, and increasing cases of cervical cancer. To address these barriers, a "see and treat" approach to screening was proposed. The objective was to integrate this method into current HIV care offered by local providers and to obtain demographic and risk factor data for use in future educational and intervention programs in the region. A cross sectional study of HIV farm workers and at-risk sex workers attending an HIV clinic was performed with visual inspection with acetic acid (VIA). Those with positive screens were offered cryotherapy. Clinic charts were reviewed retrospectively for Pap smear results for the previous year at the time of program initiation and at 12 and 18 months post-program. A total of 403 participants consented and underwent screening with VIA (306 Farm workers and 97 sex workers participated). 83.9% of participants (32.9% sex workers and 100% farm workers) were HIV +. VIA was positive in 30.5% of participants, necessitating cryotherapy. There was no significant difference in VIA positivity between HIV + farm workers and sex workers. There was a positive correlation between Pap smears and VIAs results. We demonstrate successful integration of cervical cancer screening using VIA for HIV + farm workers and sex workers into an existing HIV treatment and prevention clinic in rural South Africa, addressing and treating abnormal results promptly.

2016-01-01

Background. In nonhealthcare settings, widespread screening for acute human immunodeficiency virus (HIV) infection (AHI) is limited by cost and decision algorithms to better prioritize use of resources. Comparative cost analyses for available strategies are lacking. Methods. To determine cost-effectiveness of community-based testing strategies, we evaluated annual costs of 3 algorithms that detect AHI based on HIV nucleic acid amplification testing (EarlyTest algorithm) or on HIV p24 antigen (Ag) detection via Architect (Architect algorithm) or Determine (Determine algorithm) as well as 1 algorithm that relies on HIV antibody testing alone (Antibody algorithm). The cost model used data on men who have sex with men (MSM) undergoing community-based AHI screening in San Diego, California. Incremental cost-effectiveness ratios (ICERs) per diagnosis of AHI were calculated for programs with HIV prevalence rates between 0.1% and 2.9%. Results. Among MSM in San Diego, EarlyTest was cost-savings (ie, ICERs per AHI diagnosis less than $13.000) when compared with the 3 other algorithms. Cost analyses relative to regional HIV prevalence showed that EarlyTest was cost-effective (ie, ICERs less than $69.547) for similar populations of MSM with an HIV prevalence rate >0.4%; Architect was the second best alternative for HIV prevalence rates >0.6%. Conclusions. Identification of AHI by the dual EarlyTest screening algorithm is likely to be cost-effective not only among at-risk MSM in San Diego but also among similar populations of MSM with HIV prevalence rates >0.4%.

We demonstrate the feasibility of implementing a referral and management system for cryotherapy-ineligible women in a "screen-and-treat" cervical cancer prevention program targeting HIV-infected women in Zambia. We established criteria for patient referral, developed a training program for loop electrosurgical excision procedure (LEEP) providers, and adapted LEEP to a resource-constrained setting. We successfully trained 15 nurses to perform visual inspection with acetic acid (VIA) followed by immediate cryotherapy. Women with positive tests but ineligible for cryotherapy were referred for further evaluation. We trained four Zambian physicians to evaluate referrals, perform punch biopsy, LEEP, and manage intra-operative and post-operative complications. From January 2006 through October 2007, a total of 8823 women (41.5% HIV seropositive) were evaluated by nurses in outlying prevention clinics; of these, 1477 (16.7%) were referred for physician evaluation based on established criteria. Of the 875 (59.2% of 1147 referred) that presented for evaluation, 748 (8.4% of total screened) underwent histologic evaluation in the form of punch biopsy or LEEP. Complications associated with LEEP included anesthesia reaction (n=2) which spontaneously resolved, intra-operative (n=12) and post-operative (n=2) bleeding managed by local measures, and post-operative infection (n=12) managed with antibiotics. With adaptations for a resource-constrained environment, we have demonstrated that performing LEEP is feasible and safe, with low rates of complications that can be managed locally. It is important to establish referral and management systems using LEEP-based excisional evaluation for women with cryotherapy-ineligible lesions in VIA-based "screen-and-treat" protocols nested within HIV-care programs in resource-constrained settings.

We seek to identify and analyze, from a group of participants experienced with HIV screening, the perceived challenges and solutions to the ethical, financial, and legal considerations of emergency department (ED)-based HIV screening. We performed a qualitative analysis of the focus group discussions from the ethical, financial, and legal considerations portion of the inaugural National Emergency Department HIV Testing Consortium conference. Four groups composed of 20 to 25 consortium participants engaged in semistructured, facilitated focus group discussions. The focus group discussions were audiotaped and transcribed. A primary reader identified major themes and subthemes and representative quotes from the transcripts and summarized the discussions. Secondary and tertiary readers reviewed the themes, subthemes, and summaries for accuracy. The focus group discussions centered on the following themes. Ethical considerations included appropriateness of HIV screening in the ED and ethics of key elements of the 2006 Centers for Disease Control and Prevention HIV testing recommendations. Financial considerations included models of payment and support, role of health care insurance, financial ethics and downstream financial burdens, and advocacy approaches. Legal considerations included the adequacy of obtaining consent, partner notification, disclosure of HIV results, difficulties in addressing special populations, failure of not performing universal screening, failure to notify a person of being tested, failure to notify someone of their test results, liability of inaccurate tests, and failure to link to care. This qualitative analysis provides a broadly useful foundation to the ethical, financial, and legal considerations of implementing HIV screening programs in EDs throughout the United States.

Full Text Available Syphilis co-infection risk has increased substantially among HIV-infected men who have sex with men (MSM. Frequent screening for syphilis and treatment of men who test positive might be a practical means of controlling the risk of infection and disease sequelae in this population.We evaluated the cost-effectiveness of strategies that increased the frequency and population coverage of syphilis screening in HIV-infected MSM receiving HIV care, relative to current standard of care.We developed a state-transition microsimulation model of syphilis natural history and medical care in HIV-infected MSM receiving care for HIV. We performed Monte Carlo simulations using input data derived from a large observational cohort in Ontario, Canada, and from published biomedical literature. Simulations compared usual care (57% of the population screened annually to different combinations of more frequent (3- or 6-monthly screening and higher coverage (100% screened. We estimated expected disease-specific outcomes, quality-adjusted survival, costs, and cost-effectiveness associated with each strategy from the perspective of a public health care payer.Usual care was more costly and less effective than strategies with more frequent or higher coverage screening. Higher coverage strategies (with screening frequency of 3 or 6 months were expected to be cost-effective based on usually cited willingness-to-pay thresholds. These findings were robust in the face of probabilistic sensitivity analyses, alternate cost-effectiveness thresholds, and alternate assumptions about duration of risk, program characteristics, and management of underlying HIV.We project that higher coverage and more frequent syphilis screening of HIV-infected MSM would be a highly cost-effective health intervention, with many potentially viable screening strategies projected to both save costs and improve health when compared to usual care.

Understanding patients' perspective towards HIV screening in Malaysia is pivotal to explore challenges faced by these individuals. This would be beneficial for developing local plans to improve the health-seeking behaviours among population at risk of HIV/AIDS. A qualitative research methodology was adopted to explore HIV/AIDS patients' views about disease screening. A semi-structured interview guide was used for in-depth patient interviews. All interviews were audio-recorded and were subjected to a standard content analysis framework for data analysis. Most patients were positive about screening and the value of knowing about their status early. However, fear of social stigma, discrimination, lack of support system and lack of public understanding were identified as major concerns affecting their willingness to be screened. They were concerned about mandatory screening being implemented without improvement in support system and public education. Reluctance to seek HIV screening is an important factor contributing to transmission in developing countries. In the Malaysian context, efforts should be made to strengthen screening strategies especially in the most-at-risk populations to monitor the epidemic and target prevention strategies. In a multicultural context, HIV preventive strategies must include disease awareness, including measure to tackle barriers towards screening.

The Dynamics of an HIV/AIDS Model with Screened Disease Carriers

Directory of Open Access Journals (Sweden)

S. D. Hove-Musekwa

2009-01-01

Full Text Available The presence of carriers usually complicates the dynamics and prevention of a disease. They are not recognized as disease cases themselves unless they are screened and they usually spread the infection without them being aware. We argue that this has been one of the major causes of the spread of human immunodeficiency virus (HIV. We propose, in this paper, a model for the heterogeneous transmission of HIV/acquired immunodeficiency syndrome in the presence of disease carriers. The model allows us to assess the role of screening, as an intervention program that can slow the epidemic. A threshold value ψ*, for the screening rate is obtained. It is shown numerically that if 80% or more of the carrier population is screened, the epidemic can be contained. The qualitative analysis is done in terms of the model reproduction number R. The model has two equilibria, the disease free equilibrium and a unique endemic equilibrium. The disease free equilibrium is globally stable of R  1. A detailed discussion of the model reproduction number is given and numerical simulations are done to show the role of some of the important model parameters.

Full Text Available To assess the performance of symptom-based screening for tuberculosis (TB, alone and with chest radiography among people living with HIV (PLHIV, including pregnant women, in Western Kenya.Prospective cohort study.PLHIV from 15 randomly-selected HIV clinics were screened with three clinical algorithms [World Health Organization (WHO, Ministry of Health (MOH, and "Improving Diagnosis of TB in HIV-infected persons" (ID-TB/HIV study], underwent chest radiography (unless pregnant, and provided two or more sputum specimens for smear microscopy, liquid culture, and Xpert MTB/RIF. Performance of clinical screening was compared to laboratory results, controlling for the complex design of the survey.Overall, 738 (85.6% of 862 PLHIV enrolled were included in the analysis. Estimated TB prevalence was 11.2% (95% CI, 9.9-12.7. Sensitivity of the three screening algorithms was similar [WHO, 74.1% (95% CI, 64.1-82.2; MOH, 77.5% (95% CI, 68.6-84.5; and ID-TB/HIV, 72.5% (95% CI, 60.9-81.7]. Sensitivity of the WHO algorithm was significantly lower among HIV-infected pregnant women [28.2% (95% CI, 14.9-46.7] compared to non-pregnant women [78.3% (95% CI, 67.3-86.4] and men [77.2% (95% CI, 68.3-84.2]. Chest radiography increased WHO algorithm sensitivity and negative predictive value to 90.9% (95% CI, 86.4-93.9 and 96.1% (95% CI, 94.4-97.3, respectively, among asymptomatic men and non-pregnant women.Clinical screening missed approximately 25% of laboratory-confirmed TB cases among all PLHIV and more than 70% among HIV-infected pregnant women. National HIV programs should evaluate the feasibility of laboratory-based screening for TB, such as a single Xpert MTB/RIF test for all PLHIV, especially pregnant women, at enrollment in HIV services.

Full Text Available Project Horizonte, an open cohort of homosexual and bisexual human immunodeficiency virus (HIV-1 negative men, is a component of the AIDS Vaccine Program, in Belo Horizonte, Minas Gerais, Brazil. The objective of this study was to compare volunteers testing HIV positive at cohort entry with a sample of those who tested HIV negative in order to identify risk factors for prevalent HIV infection, in a population being screened for enrollment at Project Horizonte. A nested case-control study was conducted. HIV positive volunteers at entry (cases were matched by age and admission date to three HIV negative controls each. Selected variables used for the current analysis included demographic factors, sexual behavior and other risk factors for HIV infection. During the study period (1994-2001, among the 621 volunteers screened, 61 tested positive for HIV. Cases were matched to 183 HIV negative control subjects. After adjustments, the main risk factors associated with HIV infection were unprotected sex with an occasional partners, OR = 3.7 (CI 95% 1.3-10.6, receptive anal intercourse with an occasional partner, OR = 2.8 (95% CI 0.9-8.9 and belonging to the negro racial group, OR = 3.4 (CI 95% 1.1-11.9. These variables were associated with an increase in the risk of HIV infection among men who have sex with men at the screening for admission to an open HIV negative cohort.

Trichomonas vaginalis screening and prevention in order to impact the HIV pandemic: Isn’t it time we take this infection seriously?

Full Text Available Trichomonas vaginalis (TV is the second most common sexually transmitted infection (STI in the world. It is associated with significant morbidity in women: pelvic inflammatory disease (PID, concurrent vaginitis and sexually transmitted infections (STIs, post-operative infection, and pregnancy complications. TV infection has been implicated in HIV acquisition and transmission in men and women. There are multiple mechanisms to explain this association. TV is not routinely screened for in asymptomatic patients; however, infected individuals are most often asymptomatic. Due to the association with the spread of HIV infection, screening should not be limited to symptomatic patients or those seeking treatment for STIs. There are a variety of tests available to detect TV. Treatment of TV has demonstrated lower rates of HIV acquisition in at risk women. In HIV positive men and women, treatment decreases the amount of genital HIV shedding and subsequent infectivity. Initiation of an effective TV screening and treatment program in HIV positive and HIV susceptible populations may limit further transmission of HIV

We evaluated three cervical cancer screening methods to detect cervical intraepithelial neoplasia grade 2 and above (CIN 2+ in HIV-infected women in South Africa; Pap smear, visual inspection with 5% acetic acid (VIA and human papillomavirus detection (HPV.HIV-infected women aged 18-65 were recruited in Johannesburg. A cross-sectional study evaluating three screening methods for the detection of the histologically-defined gold standard CIN-2 + was performed. Women were screened for cervical abnormalities with the Digene HC2 assay (HPV, Pap smear and VIA. VIA was performed by clinic nurses, digital photographs taken and then later reviewed by specialist physicians. The sensitivity, specificity and predictive valves for CIN-2 + were calculated using maximum likelihood estimators.1,202 HIV-infected women participated, with a median age of 38 years and CD4 counts of 394 cells/mm(3. One third of women had a high grade lesion on cytology. VIA and HPV were positive in 45% and 61% of women respectively. Estimated sensitivity/specificity for HPV, Pap smear and VIA for CIN 2+ was 92%/51.4%, 75.8%/83.4% and 65.4/68.5% (nurse reading, respectively. Sensitivities were similar, and specificities appeared significantly lower for the HPV test, cytology and VIA among women with CD4 counts ≤200 cells/mm(3 as compared to CD4 counts >350 cells/mm(3.Although HPV was the most sensitive screening method for detecting CIN 2+, it was less specific than conventional cytology and VIA with digital imaging review. Screening programs may need to be individualized in context of the resources and capacity in each area.

Full Text Available Abstract Background When detected, HIV can be effectively treated with antiretroviral therapy. Nevertheless in the U.S. approximately 25% of those who are HIV-infected do not know it. Much remains unknown about how to increase HIV testing rates. New Internet outreach methods have the potential to increase disease awareness and screening among patients, especially as electronic personal health records (PHRs become more widely available. In the US Department of Veterans' Affairs medical care system, 900,000 veterans have indicated an interest in receiving electronic health-related communications through the PHR. Therefore we sought to evaluate the optimal circumstances and conditions for outreach about HIV screening. In an exploratory, qualitative research study we examined patient and provider perceptions of Internet-based outreach to increase HIV screening among veterans who use the Veterans Health Administration (VHA health care system. Findings We conducted two rounds of focus groups with veterans and healthcare providers at VHA medical centers. The study's first phase elicited general perceptions of an electronic outreach program to increase screening for HIV, diabetes, and high cholesterol. Using phase 1 results, outreach message texts were drafted and then presented to participants in the second phase. Analysis followed modified grounded theory. Patients and providers indicated that electronic outreach through a PHR would provide useful information and would motivate patients to be screened for HIV. Patients believed that electronic information would be more convenient and understandable than information provided verbally. Patients saw little difference between messages about HIV versus about diabetes and cholesterol. Providers, however, felt patients would disapprove of HIV-related messages due to stigma. Providers expected increased workload from the electronic outreach, and thus suggested adding primary care resources and devising

The WHO called for the elimination of maternal-to-child transmission (MTCT) of HIV and syphilis, a harmonised approach for the improvement of health outcomes for mothers and children. Testing early in pregnancy, treating seropositive pregnant women and preventing syphilis reinfection can prevent MTCT of HIV and syphilis. We assessed the health and economic outcomes of a dual testing strategy in a simulated cohort of 100 000 antenatal care patients in Malawi. We compared four screening algorithms: (1) HIV rapid test only, (2) dual HIV and syphilis rapid tests, (3) single rapid tests for HIV and syphilis and (4) HIV rapid and syphilis laboratory tests. We calculated the expected number of adverse pregnancy outcomes, the expected costs and the expected newborn disability-adjusted life years (DALYs) for each screening algorithm. The estimated costs and DALYs for each screening algorithm were assessed from a societal perspective using Markov progression models. Additionally, we conducted a Monte Carlo multiway sensitivity analysis, allowing for ranges of inputs. Our cohort decision model predicted the lowest number of adverse pregnancy outcomes in the dual HIV and syphilis rapid test strategy. Additionally, from the societal perspective, the costs of prevention and care using a dual HIV and syphilis rapid testing strategy was both the least costly ($226.92 per pregnancy) and resulted in the fewest DALYs (116 639) per 100 000 pregnancies. In the Monte Carlo simulation the dual HIV and syphilis algorithm was always cost saving and almost always reduced DALYs compared with HIV testing alone. The results of the cost-effectiveness analysis showed that a dual HIV and syphilis test was cost saving compared with all other screening strategies. Updating existing prevention of mother-to-child HIV transmission programmes in Malawi and similar countries to include dual rapid testing for HIV and syphilis is likely to be advantageous.

Background HIV screening in a labour ward is the last opportunity to initiate an antiretroviral prophylaxis among pregnant women living with HIV to prevent mother-to-child HIV transmission. Little is known about the feasibility and acceptability of HIV screening during labour in West Africa. Findings A cross-sectional survey was conducted in the labour ward at the Tokoin Teaching Hospital in Lomé (Togo) between May and August 2010. Pregnant women admitted for labour were randomly selected to enter the study and were interviewed on the knowledge of their HIV status. Clinical and biological data were collected from the individual maternal health chart. HIV testing or re-testing was systematically proposed to all pregnant women. Among 1530 pregnant women admitted for labour, 508 (32.2%) were included in the study. Information on HIV screening was available in the charts of 359 women (71%). Overall, 467 women accepted HIV testing in the labour ward (92%). The HIV prevalence was 8.8% (95% confidence interval: 6.4 to 11.7%). Among the 41 women diagnosed as living with HIV during labour, 34% had not been tested for HIV during pregnancy and were missed opportunities. Antiretroviral prophylaxis had been initiated antenatally for 24 women living with HIV and 17 in the labour room. Conclusions This study is the first to show in West Africa that HIV testing in a labour room is feasible and well accepted by pregnant women. HIV screening in labour rooms needs to be routinely implemented to reduce missed opportunities for intervention aimed at HIV care and prevention, especially PMTCT. PMID:22905362

Full Text Available Abstract Background The proven benefit of integrating cervical cancer screening programme into HIV care has led to its adoption as a standard of care. However this is not operational in most HIV clinics in Nigeria. Of the various reasons given for non-implementation, none is backed by scientific evidence. This study was conducted to assess the willingness and acceptability of cervical cancer screening among HIV positive Nigerian women. Methods A cross sectional study of HIV positive women attending a large HIV treatment centre in Lagos, Nigeria. Respondents were identified using stratified sampling method. A pretested questionnaire was used to obtain information by trained research assistants. Obtained information were coded and managed using SPSS for windows version 19. Multivariate logistic regression model was used to determine independent predictor for acceptance of cervical cancer screening. Results Of the 1517 respondents that returned completed questionnaires, 853 (56.2% were aware of cervical cancer. Though previous cervical cancer screening was low at 9.4%, 79.8% (1210 accepted to take the test. Cost of the test (35.2% and religious denial (14.0% were the most common reasons given for refusal to take the test. After controlling for confounding variables in a multivariate logistic regression model, having a tertiary education (OR = 1.4; 95% CI: 1.03-1.84, no living child (OR: 1.5; 95% CI: 1.1-2.0, recent HIV diagnosis (OR: 1.5; 95% CI: 1.1-2.0 and being aware of cervical cancer (OR: 1.5; 95% CI: 1.2-2.0 retained independent association with acceptance to screen for cervical cancer. Conclusions The study shows that HIV positive women in our environment are willing to screen for cervical cancer and that the integration of reproductive health service into existing HIV programmes will strengthen rather than disrupt the services.

Screening for HIV antibodies every 6 months costs $30,700/QALY gained. Screening for HIV antibodies and viral RNA every 6 months has an ICER of $65,900/QALY gained. Strategies including HCV testing have ICERs exceeding $100,000/QALY gained unless awareness of HCV-infection status results in a substantial reduction in needle-sharing behavior.Although annual screening for antibodies to HIV and HCV is modestly cost effective compared to no screening, more frequent screening for HIV provides additional benefit at less cost. Screening individuals in ORT every 3-6 months for HIV infection using both antibody and viral RNA technologies and initiating ART for acute HIV infection appears cost effective.

Cervical cancer is the major cause of death from cancer in Africa. We wanted to assess the prevalence of human papillomavirus (HPV) infections and associated risk factors and to determine whether HPV testing could serve as a screening method for squamous intraepithelial lesions (SILs) in Rwanda. We also wanted to obtain a broader understanding of the underlying risk factors for the establishment of HPV infection in Rwanda. A total of 206 HIV-positive women, 172 HIV-negative women and 22 women with unknown HIV status were recruited at the University Teaching Hospitals of Kigali (UTHK) and of Butare (UTHB) in Rwanda. Participants underwent an interview, cervical sampling for a Thinprep Pap test and a screening test analysing 37 HPV strains. Only 27% of HIV-positive women and 7% of HIV-negative women had been screened for cervical cancer before. HPV16 and HPV52 were the most common HPV strains. HIV-positive women were more commonly infected with high-risk (HR) HPV and multitype HPV than HIV-negative women. The sensitivity was 78% and the specificity 87% to detect high-grade SIL (HSIL) with HPV screening. Among HIV-negative women, being divorced was positively associated with HR-HPV infection, while hepatitis B, Trichomonas vaginalis infection and HR-HPV infection were factors positively associated with SILs. Ever having had gonorrhoea was positively associated with HR-HPV infection among HIV-positive women. HR-HPV infection and the number of live births were positively associated with SILs. The currently used quadrivalent vaccine may be insufficient to give satisfactory HPV coverage in Rwanda. HPV Screening may be effective to identify women at risk of developing cervical cancer, particularly if provided to high-risk patients. © 2017 British HIV Association.

Screening of modifiable cardiovascular disease (CVD) risk factors is recommended but not routinely provided for HIV-infected patients, especially in low-resource settings. Potential concerns include limited staff time and low patient acceptability, but little empirical data exists. As part of a pilot study of screening in a large urban HIV clinic in Swaziland, we conducted a time-motion study to assess the impact of screening on patient flow and HIV service delivery and exit interviews to assess patient acceptability. A convenience sample of patients ≥40 years of age attending routine HIV clinic visits was screened for hypertension, diabetes, hyperlipidemia and tobacco smoking. We observed HIV visits with and without screening and measured time spent on HIV and CVD risk factor screening activities. We compared screened and unscreened patients on total visit time and time spent receiving HIV services using Wilcoxon rank-sum tests. A separate convenience sample of screened patients participated in exit interviews to assess their satisfaction with screening. We observed 172 patient visits (122 with CVD risk factor screening and 50 without). Screening increased total visit time from a median (range) of 4 minutes (2 to 11) to 15 minutes (9 to 30) (p < 0.01). Time spent on HIV care was not affected: 4 (2 to 10) versus 4 (2 to 11) (p = 0.57). We recruited 126 patients for exit interviews, all of whom indicated that they would recommend screening to others. Provision of CVD risk factor screening more than tripled the length of routine HIV clinic visits but did not reduce the time spent on HIV services. Programme managers need to take longer visit duration into account in order to effectively integrate CVD risk factor screening and counselling into HIV programmes. © 2018 The Authors.

The primary endpoint was to evaluate the use of HIV testing methods by French primary care providers: Elisa laboratory screening, instant result HIV diagnostic test and rapid result HIV diagnostic test. The secondary endpoints were the population screening rate of unknown HIV status consulting during the study period, reasons for screening and for choosing the specific screening method, the investigators' satisfaction with the rapid diagnostic test (RDT) and problems encountered. National prospective interventional study with French family physicians (FP) from December 2013 to December 2014. FPs enrolled all consenting adults consulting for an HIV screening test during a 6-month period: the choice was an Elisa laboratory test or one of the two RDTs. During the study period, 43 FPs included 981 patients. HIV screening was performed for the first time for 31.6% of patients; 767 (78.2%) Elisa laboratory test prescriptions and 214 (21.8%) RDTs were performed, leading to a screening rate of 1.3%. For 120 (15.7%) of the Elisa laboratory tests, the result was not reported and six RDTs were not valid. Nine patients were diagnosed as HIV-infected (0.9%): five with Elisa laboratory test and four with RDT. Almost 90% of FPs were willing to keep on using RDTs in their daily practice. In general practice, RDTs may be an important additional tool to traditional HIV screening. They could account for one in five tests prescribed in this context. Copyright © 2017 Elsevier Masson SAS.

Full Text Available Background: Adherence to screening guidelines has been widely accepted to reduce morbidity, mortality, and cost outcomes. The aim of this study was to identify predictors of adherence to screening guidelines for chronic diseases of lifestyle (CDL, cancers, and HIV in a health-insured population in South Africa, some of whom voluntarily opt into a wellness program that incentivizes screening. Method: A cross-sectional study for the period 2007–2011 was conducted using a random sample of 170,471 health insurance members from a single insurer. Adherence to screening guidelines was calculated from medical claims data. Results: Adherence to screening guidelines ranged from 1.1% for colorectal cancer to 40.9% for cholesterol screening. Members of the wellness program were up to three times more likely to screen for diseases (odds ratio [OR]=3.2 for HIV screening, confidence interval [CI]=2.75–3.73. Plan type (full comprehensive plan was most strongly associated with cholesterol screening (OR=3.53, CI=3.27–3.80, and most negatively associated (hospital-only core plan with cervical cancer screening (OR= 0.44, CI=0.28–0.70. Gender was a negative predictor for glucose screening (OR=0.88, CI=0.82–0.96. Provincial residence was most strongly associated with cervical cancer screening (OR=1.89, CI=0.65–5.54. Conclusion: Adherence to screening recommendations was <50%. Plan type, gender, provincial residence, and belonging to an incentivized wellness program were associated with disproportionate utilization of screening services, even with equal payment access.

African American women have disproportionately high prevalence rates of HIV and cervical cancer. HIV-infected women are significantly less likely to obtain recommended cervical cancer screenings than HIV-uninfected women. The purpose of this study was to examine sociocultural and structural factors associated with cervical cancer screening among HIV-infected African American in Alabama. The PEN-3 Model and the Health Belief Model were used as theoretical frameworks. In-depth interviews were conducted with twenty HIV-infected African American women to identify perceptions, enablers, and nurturers, perceived susceptibility, perceived severity, and perceived benefits related to cervical cancer and screening. The most common positive perceptions, enablers, and nurturers that contributed to cervical cancer screening included internal motivation and awareness of the importance of HIV-infected women getting Pap tests due to their weakened immune system. Negative perceptions, enablers, and nurturers included lack of knowledge about cervical cancer and screening, and lack of perceived susceptibility to cervical cancer. The results of this study can be used to guide the development of culturally relevant cervical cancer and screening education interventions aimed at increasing cervical cancer screening adherence among HIV-infected African American women.

Stigma and discrimination, particularly in access to healthcare, remains a major problem for people Infected with HIV in most parts of India. We did a multicentre study (n = 10) with a cross-sectional survey design using a standardized, interviewer-administered questionnaire. A total of 2200 healthcare providers participated. The knowledge, attitude and practice (KAP) related to HIV service delivery were very poor with a mean overall KAP score of only 49.7% (CI: 49.1-50.3). Only 5%, 5% and 1% of the participants scored more than 75% separately for the dimensions of knowledge, attitude and practice, respectively. Only 24.4% and 36.7% of responders knew that HIV screening was not recommended prior to surgery and pre-employment check-up. Many doctors (19.4%) had refused treatment to people living with HIV/AIDS (PLHA) at least some of the time and nearly half (47.2%) identified and labelled them; 23.9% isolated them in separate care areas and 13.3% postponed or changed treatment based on the patient's HIV status. Screening for HIV prior to elective surgery was done by 67% of providers. While 64.7% of responders were aware of the existence of national guidelines on and recommendations for HIV testing, only 38.4% had read the policy document. There is a growing need to provide care, support and treatment to a large number of PLHA. The capacity of healthcare providers must be urgently built up so as to improve their knowledge of and attitude to HIV to enable them to deliver evidence-based and compassionate care to PLHA in various healthcare settings.

Low bone mineral density, which leads to osteoporosis and fracture risk, is an emerging clinical problem in HIV-infected patients. Our evidence-based practice project screened a convenience sample of 225 HIV-infected men for low bone mineral density using the Osteoporosis Self-Assessment Tool, and of those men, 173 were also screened by quantitative ultrasound of the calcaneus. One hundred twelve men had low bone mineral density by either or both screening methods. Seventy-one of these 112 men were tested by dual-energy x-ray absorptiometry and 73% had low bone mineral density. The positive protective value of the Osteoporosis Self-Assessment Tool was 73% and for quantitative ultrasound was 88%. These results suggest that routine low bone mineral density screening should be included as standard practice for all HIV-infected patients. Copyright © 2014 Association of Nurses in AIDS Care.

Although non-AIDS defining malignancies are rapidly increasing as HIV-infected subjects live longer, little is know about the results of screening for colonic neoplasms (adenomatous polyps and adenocarcinomas) in this population. We conducted a screening colonoscopy study to determine the prevalence of colonic neoplasms in 136 asymptomatic HIV-infected subjects >or=50 years of age and 272 asymptomatic uninfected control subjects matched for age, sex, and family history of colorectal cancer. Advanced neoplasms were defined as adenomas >or=10 mm or any adenoma, regardless of size, with villous histology, high-grade dysplasia, or adenocarcinoma. The prevalence of neoplastic lesions was significantly higher in HIV-infected subjects than in control subjects (62.5% vs 41.2%, pscreening colonoscopy should be offered to HIV-infected subjects, but the age of initiation and the optimal frequency of screening require further study.

The US Centers for Disease Control and Prevention (CDC) recommend human immunodeficiency virus (HIV) screening for all persons aged 13 to 64 years who present to a health care provider. We sought to improve adherence to the CDC guidelines on the Internal Medicine Resident Hospital Service. We surveyed residents about the CDC guidelines, sent email reminders, provided education, and engaged them in friendly competition. Credit for guideline adherence was awarded if an offer of HIV screening was documented at admission, if a screening test was performed, or if a notation in the resident sign out sheet indicated why screening was not performed. We examined HIV screening of a postintervention group of patients admitted between August 8, 2012, and June 30, 2013, and compared them to a preintervention group admitted between August 1, 2011, and June 30, 2012. Postintervention offers of HIV screening increased significantly (7.9% [44/559] vs 55.5% [300/541]; P<.001), as did documentation of residents' contemplation of screening (8.9% [50/559] vs 67.5% [365/541]; P<.001). A significantly higher proportion of HIV screening tests was ordered postintervention (7.7% [43/559] vs 44.4% [240/541]; P<.001). Monthly HIV screening documentation ranged from 0% (0/53) to 17% (9/53) preintervention, whereas it ranged from 30.6% (11/36) to 100% (62/62) postintervention. HIV screening adherence can be improved through resident education, friendly competition, and system reminders. Barriers to achieving sustained adherence to the CDC guidelines include a heterogeneous patient population and provider discomfort with the subject.

New York State adopted a new HIV testing law in 2010 requiring medical providers to offer an HIV test to all eligible patients aged 13-64 years during emergency room or ambulatory care visits. Since then, Wyckoff Heights Medical Center (WHMC) in Brooklyn, New York, began implementing routine HIV screening organization-wide using a compliance, behavior-modification, and continuous quality-improvement process. WHMC first implemented HIV screening in the emergency department (ED) and evaluated progress with the following monthly indicators: HIV tests offered, HIV tests accepted, HIV tests ordered (starting in December 2013), HIV tests administered, positive HIV tests, and linkage to HIV care. Compliance with the delivery of HIV testing was determined by the proportion of patients who, after accepting a test, received one. During August 2013 through July 2014, of 57,852 eligible patients seen in the WHMC ED, a total of 31,423 (54.3%) were offered an HIV test. Of those, 8,229 (26.2%) patients accepted a test. Of those, 6,114 (74.3%) underwent a test. A total of 26 of the 6,114 patients tested (0.4%) had a positive test, and 24 of the 26 HIV-positive patients were linked to HIV medical care. By July 2014, the monthly proportion of patients offered a test was 62%; the proportion of those offered a test who had a test ordered was 98%, and the proportion of those with a test ordered who were tested was 81%. Testing compliance increased substantially at the WHMC ED, from 77% in December 2013 to >98% in July 2014. Using compliance-monitoring, behavior-modification, and continuous quality-improvement processes produced substantial increases in offers and HIV test completion. WHMC is replicating this approach across departments, and other hospitals implementing routine HIV screening programs should consider this approach as well.

Full Text Available BACKGROUND: The AutoDock family of software has been widely used in protein-ligand docking research. This study compares AutoDock 4 and AutoDock Vina in the context of virtual screening by using these programs to select compounds active against HIV protease. METHODOLOGY/PRINCIPAL FINDINGS: Both programs were used to rank the members of two chemical libraries, each containing experimentally verified binders to HIV protease. In the case of the NCI Diversity Set II, both AutoDock 4 and Vina were able to select active compounds significantly better than random (AUC = 0.69 and 0.68, respectively; p<0.001. The binding energy predictions were highly correlated in this case, with r = 0.63 and iota = 0.82. For a set of larger, more flexible compounds from the Directory of Universal Decoys, the binding energy predictions were not correlated, and only Vina was able to rank compounds significantly better than random. CONCLUSIONS/SIGNIFICANCE: In ranking smaller molecules with few rotatable bonds, AutoDock 4 and Vina were equally capable, though both exhibited a size-related bias in scoring. However, as Vina executes more quickly and is able to more accurately rank larger molecules, researchers should look to it first when undertaking a virtual screen.

Cervical screening by means of annual Papanicolaou (PAP) smears has been recommended for all women living with HIV. We analysed the results of our annual PAP smear screening program to identify low-risk subgroups for less rigorous screening. The study comprised 369 women followed at the Helsinki University Hospital 2002-2013, with a total of 2033 PAP smear results. We analyzed the temporal changes in PAP smear findings. Logistic regression analysis for binominal dependent variables was used for assessing risk factors for ever having cytological squamous intraepithelial lesions (hereafter referred as SIL) using generalized estimating equations taking into account multiple observations of each patient. Most women had well-controlled HIV, especially towards the end of the study. PAP smear results improved substantially. At the time of each individual's last PAP smear, 90.0% of the findings displayed normal results. Conversely, the rate of SIL decreased from 16.8% to 4.6% from 2002 to 2013. In multivariate analysis the risk of SIL was significantly lower in women with consecutive normal PAP smear findings during the first two years of follow up [odds ratio (OR) 0.21, 95% confidence interval (CI) 0.10-0.45, p 500 cells/μL (OR 0.11, 95% CI 0.05-0.26, p < 0.001). Widespread use of combination antiretroviral therapy (cART) and systematic cervical screening has reduced the rate of abnormal PAP smears. It seems feasible to identify low-risk women by combining HIV-related information and PAP smear results. Screening low-risk women living with HIV at three-year intervals similar to HIV-negative women appears justified. © 2017 Nordic Federation of Societies of Obstetrics and Gynecology.

Full Text Available Abstract Background The 2006 Centers for Disease Control and Prevention (CDC HIV testing guidelines recommend screening for HIV infection in all healthcare settings, including the emergency department (ED. In urban areas with a high background prevalence of HIV, the ED has become an increasingly important site for identifying HIV infection. However, this public health policy has been operationalized using different models. We sought to describe the development and implementation of HIV testing programs in three EDs, assess factors shaping the adoption and evolution of specific program elements, and identify barriers and facilitators to testing. Methods We performed a qualitative evaluation using in-depth interviews with fifteen 'key informants' involved in the development and implementation of HIV testing in three urban EDs serving sizable racial/ethnic minority and socioeconomically disadvantaged populations. Testing program HIV prevalence ranged from 0.4% to 3.0%. Results Three testing models were identified, reflecting differences in the use of existing ED staff to offer and perform the test and disclose results. Factors influencing the adoption of a particular model included: whether program developers were ED providers, HIV providers, or both; whether programs took a targeted or non-targeted approach to patient selection; and the extent to which linkage to care was viewed as the responsibility of the ED. A common barrier was discomfort among ED providers about disclosing a positive HIV test result. Common facilitators were a commitment to underserved populations, the perception that testing was an opportunity to re-engage previously HIV-infected patients in care, and the support and resources offered by the medical setting for HIV-infected patients. Conclusions ED HIV testing is occurring under a range of models that emerge from local realities and are tailored to institutional strengths to optimize implementation and overcome provider

There is evidence that HIV prevention programs for sex workers, especially female sex workers, are cost-effective in several contexts, including many western countries, Thailand, India, the Democratic Republic of Congo, Kenya, and Zimbabwe. The evidence that sex worker HIV prevention programs work must not inspire complacency but rather a renewed effort to expand, intensify, and maximize their impact. The PLOS Collection "Focus on Delivery and Scale: Achieving HIV Impact with Sex Workers" highlights major challenges to scaling-up sex worker HIV prevention programs, noting the following: sex worker HIV prevention programs are insufficiently guided by understanding of epidemic transmission dynamics, situation analyses, and programmatic mapping; sex worker HIV and sexually transmitted infection services receive limited domestic financing in many countries; many sex worker HIV prevention programs are inadequately codified to ensure consistency and quality; and many sex worker HIV prevention programs have not evolved adequately to address informal sex workers, male and transgender sex workers, and mobile- and internet-based sex workers. Based on the wider collection of papers, this article presents three major clusters of recommendations: (i) HIV programs focused on sex workers should be prioritized, developed, and implemented based on robust evidence; (ii) national political will and increased funding are needed to increase coverage of effective sex worker HIV prevention programs in low and middle income countries; and (iii) comprehensive, integrated, and rapidly evolving HIV programs are needed to ensure equitable access to health services for individuals involved in all forms of sex work.

Screening results of 488 pregnant women aged 15-44 years whose blood samples had been tested on-site, using First Response® HIV 1/2, and confirmed with INNO-LIA™ HIV I/II Score were used. Of this total, 178 were reactive (HIV I, 154; HIV II, 2; and HIV I and HIV II, 22). Of the 154 HIV I-reactive samples, 104 were confirmed to be HIV I-positive and 2 were confirmed to be HIV II-positive, while 48 were confirmed to be negative [false positive rate = 17.44% (13.56-21.32)]. The two HIV II samples submitted were confirmed to be negative with the confirmatory test. For the 22 HIV I and HIV II samples, 7 were confirmed to be HIV I-positive and 1 was confirmed to be HIV I- and HIV II-positive, while 14 were confirmed to be negative. Of the 310 nonreactive samples, 6 were confirmed to be HIV I-positive and 1 was confirmed to be HIV II-positive [false negative rate = 5.79% (1.63-8.38)], while 303 were negative. False negative outcomes will remain unconfirmed, with no management options for the client. False negative rate of 5.79% requires attention, as its resultant implications on control of HIV/AIDS could be dire.

During 2016, the National Health Laboratory Service (NHLS) introduced laboratory-based reflexed Cryptococcal antigen (CrAg) screening to detect early Cryptococcal disease in immunosuppressed HIV+ patients with a confirmed CD4 count of 100 cells/μl or less. The aim of this study was to assess cost-per-result of a national screening program across different tiers of laboratory service, with variable daily CrAg test volumes. The impact of potential ART treatment guideline and treatment target changes on CrAg volumes, platform choice and laboratory workflow are considered. CD4 data (with counts per-result was calculated for four scenarios, including the existing service status quo (Scenario-I), and three other settings (as Scenarios II-IV) which were based on information from recent antiretroviral (ART) guidelines, District Health Information System (DHIS) data and UNAIDS 90/90/90 HIV/AIDS treatment targets. Scenario-II forecast CD4 testing offered only to new ART initiates recorded at DHIS. Scenario-III projected all patients notified as HIV+, but not yet on ART (recorded at DHIS) and Scenario-IV forecast CrAg screening in 90% of estimated HIV+ patients across South Africa (also DHIS). Stata was used to assess daily CrAg volumes at the 5th, 10th, 25th, 50th, 75th, 90th and 95th percentiles across 52 CD4-laboratories. Daily volumes were used to determine technical effort/ operator staff costs (% full time equivalent) and cost-per-result for all scenarios. Daily volumes ranged between 3 and 64 samples for Scenario-I at the 5th and 95th percentile. Similarly, daily volumes ranges of 1-12, 2-45 and 5-100 CrAg-directed samples were noted for Scenario's II, III and IV respectively. A cut-off of 30 CrAg tests per day defined use of either LFA or EIA platform. LFA cost-per-result ranged from $8.24 to $5.44 and EIA cost-per-result between $5.58 and $4.88 across the range of test volumes. The technical effort across scenarios ranged from 3.2-27.6% depending on test volumes and

Variation in the Viral Hepatitis and HIV Policies and Practices of Methadone Maintenance Programs.

Science.gov (United States)

Jessop, Amy B; Hom, Jeffrey K; Burke, Monika

Patients prescribed methadone maintenance treatment (MMT) demonstrate elevated prevalence of hepatitis B virus (HBV), hepatitis C virus, and HIV. Government agencies recommend testing for these infections in MMT programs, but uptake is limited. We audited infection-related policies and practices of all 14 MMT programs in Philadelphia, Pennsylvania, in 2015. Results were tabulated and compared with the results from a 2010 audit of 10 of 12 MMT programs. The audit focused on which patients are tested, timing and frequency, specific tests ordered, vaccination, and communication of test results. Written policies were nonspecific, offering little guidance on appropriate testing. The principal change in policy between 2010 and 2015 involved adding clearer guidance for communication of results to patients. In 2010 and 2015, all MMT programs tested new patients for hepatitis C virus antibodies, although retesting of existing patients varied. HBV testing increased from 2010 to 2015, though it was not uniform, with 5 programs testing for HBV surface antibodies and 10 programs testing for HBV surface antigens. Six programs assessed hepatitis vaccination status, but only 1 administered vaccines. In 2010, city-sponsored HIV antibody testing was available at all MMT programs. Without this program in 2015, few MMT programs conducted HIV testing. Despite limited hepatitis and HIV screening in MMT programs nationally, this study shows that testing can be incorporated into routine procedures. MMT programs are positioned to play an integral role in the identification of patients with chronic infections, but additional guidance and resources are required to maximize their impact.

Seven rapid diagnosis tests (RDTs) of HIV were evaluated by a panel group who collected serum samples from patients in Abidjan (HIV-1 = 203, HIV-2 = 25, HIV-dual = 25, HIV = 305). Kit performances were recorded after the reference techniques (enzyme-linked immunosorbent assay). The following RDTs showed a sensitivity of 100% and a specificity higher than 99%: Determine, Oraquick, SD Bioline, BCP, and Stat-Pak. These kits were used to establish infection screening strategies. The combination with 2 or 3 of these tests in series or parallel algorithms showed that series combinations with 2 tests (Oraquick and Bioline) and 3 tests (Determine, BCP, and Stat-Pak) gave the best performances (sensitivity, specificity, positive predictive value, and negative predictive value of 100%). However, the combination with 2 tests appeared to be more onerous than the combination with 3 tests. The combination with Determine, BCP, and Stat-Pak tests serving as a tiebreaker could be an alternative to the HIV/AIDS serological screening in Abidjan.

Lung cancer is the leading cause of non-AIDS-defining cancer deaths among HIV-infected individuals. Although lung cancer screening with low-dose computed tomography (LDCT) is endorsed by multiple national organizations, whether HIV-infected individuals would have similar benefit as uninfected individuals from lung cancer screening is unknown. Our objective was to determine the benefits and harms of lung cancer screening among HIV-infected individuals. We modified an existing simulation model, the Lung Cancer Policy Model, for HIV-infected patients. Veterans Aging Cohort Study, Kaiser Permanente Northern California HIV Cohort, and medical literature. Target population: HIV-infected current and former smokers. Lifetime. Population. Annual LDCT screening from ages 45, 50, or 55 until ages 72 or 77 years. Benefits assessed included lung cancer mortality reduction and life-years gained; harms assessed included numbers of LDCT examinations, false-positive results, and overdiagnosed cases. For HIV-infected patients with CD4 at least 500 and 100% antiretroviral therapy adherence, screening using the Centers for Medicare & Medicaid Services criteria (age 55-77, 30 pack-years of smoking, current smoker or quit within 15 years of screening) would reduce lung cancer mortality by 18.9%, similar to the mortality reduction of uninfected individuals. Alternative screening strategies utilizing lower screening age and/or pack-years criteria increase mortality reduction, but require more LDCT examinations. Strategies assumed 100% screening adherence. Lung cancer screening reduces mortality in HIV-infected patients with CD4 at least l500, with a number of efficient strategies for eligibility, including the current Centers for Medicare & Medicaid Services criteria.

With improved survival and aging, more persons living with HIV/AIDS (PLWHA) are at risk for colorectal cancer (CRC). This retrospective longitudinal study evaluated patient characteristics associated with CRC screening in our HIV cohort. Patients were followed beginning at age 50 years during a study period from January 1, 2003 to December 31, 2010 (n=265). During a median follow-up time of 1.7 years, only 30% of patients underwent CRC screening. The majority of screened patients received endoscopic screening (colonoscopy, 86%; sigmoidoscopy, 8%); among these patients, results were available for 68/75, and adenomatous polyps were found in 13%. No cases of CRC were reported. Among unscreened patients, only 23% had an external primary care provider, indicating an HIV provider was the expected source for CRC screening referral in the majority. Patients with time-varying suppressed HIV viral load were more likely to receive screening (HRadjusted=1.74; 95% CI: 1.05-2.87), independent of CD4 count. Our findings suggest HIV providers are more likely to address non-HIV-related healthcare maintenance when HIV is controlled. In addition, a significant number of neoplastic lesions are likely being missed in PLWHA who have not been screened for CRC. Provision of evidence-based preventive care in addition to HIV care is required for the aging population of PLWHA.

The World Health Organization (WHO)'s cervical cancer screening guidelines for limited-resource settings recommend sequential screening followed by same-day treatment under a "screen-and-treat" approach. We aimed to (1) assess feasibility and clinical outcomes of screening HIV-positive and HIV-negative Cameroonian women by pairing visual inspection with acetic acid and Lugol's iodine enhanced by digital cervicography (VIA/VILI-DC) with careHPV, a high-risk human papillomavirus (HR-HPV) nucleic acid test designed for low-resource settings; and (2) determine persistence of HR-HPV infection after one-year follow-up to inform optimal screening, treatment, and follow-up algorithms. We co-tested 913 previously unscreened women aged ≥30years and applied WHO-recommended treatment for all VIA/VILI-DC-positive women. Baseline prevalence of HR-HPV and HIV were 24% and 42%, respectively. On initial screen, 44 (5%) women were VIA/VILI-DC-positive, of whom 22 had HR-HPV infection, indicating 50% of women screened false-positive and would have been triaged for unnecessary same-day treatment. VIA/VILI-DC-positive women with HIV infection were three times more likely to be HR-HPV-positive than HIV-negative women (65% vs. 20%). All women positive for either VIA/VILI-DC or HR-HPV (n=245) were invited for repeat co-testing after one year, of which 136 (56%) returned for follow-up. Of 122 women who were HR-HPV-positive on initial screen, 60 (49%) re-tested negative, of whom 6 had received treatment after initial screen, indicating that 44% of initially HR-HPV-positive women spontaneously cleared infection after one year without treatment. Women with HIV were more likely to remain HR-HPV-positive on follow-up than HIV-negative women (61% vs. 22%, p<0.001). Treatment was offered to all VIA/VILI-DC positive women on initial screen, and to all women screening VIA/VILI-DC or HR-HPV positive on follow-up. We found careHPV co-testing with VIA/VILI-DC to be feasible and valuable in

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.

Objectives The International HIV Dementia Scale (IHDS) was developed to screen for HIV-associated dementia (HAD), but it has been used more generally for HIV-associated neurocognitive disorder (HAND). This study sought to examine the accuracy of the IHDS in a cohort of Brazilian HIV-infected individuals and compare its performance to an alternative screening battery for detecting HAND. Methods 108 participants (including 60 HIV-infected persons), completed the IHDS and a gold standard neuropsychological (NP) battery of 17 tests. As alternative screening method, all possible three-test combinations from the NP battery were examined and a superiority index (a marker of specificity and sensitivity) was calculated. Results Sensitivity and specificity to HAND using the standard IHDS cutpoint of 10 were 36% and 75% respectively. The best balance between sensitivity and specificity was accomplished with a modified cutpoint of 11.5, which yielded sensitivity of 72% and specificity of 58%. The top two most sensitive test combinations, compared to the gold standard NP battery, were Trail Making Test A, WAIS-III Digit Symbol (DS) and HVLT-R Total Recall (sensitivity 91%, specificity 96%), and DS, BVMT-R Total Recall and Grooved Pegboard Test-Dominant Hand (sensitivity 94%, specificity 91%). Conclusions Both test combinations can be administered in under 10 minutes and were more accurate than the IHDS in classifying HIV+ participants as NP impaired or unimpaired. These data suggest that demographically corrected T-scores from commonly used NP measures with modest time and material demands can improve identification of patients with HAND who may benefit from a more extensive NP examination.

universal screening in pregnancy for HIV is common and migrant women are an identified high risk group. The increasing mobility within countries and migration across borders affects the growing prevalence of HIV, but little is understood about how migrant women view risk of HIV in relation to pregnancy. to explore factors that relate to HIV screening decisions for migrant women. the HIV antenatal counselling experiences of pregnant migrant women were explored in a Grounded Theory study. the four settings were antenatal care units of border hospitals in northern Thailand 38 migrant pregnant women who had been through the HIV screening process at participating antenatal clinics as well as 26 health personnel at the units were purposively recruited and interviewed about their experiences and attitudes to HIV counselling and testing for this group. in-depth interviews were conducted from January to March 2008. The grounded theory technique of open coding was employed and constant comparison took place throughout until saturation was achieved. four themes were identified as common to the women and the health professionals: ineffective provision of information; internal and external barriers to information; implications of migrant status; and perception of risk. where language barriers exist interpreters are required and creative approaches to information giving that do not rely on text are necessary. The organisation of clinics does not currently meet the needs of migrant women and causes stress for health staff due to time constraints. Extra resources should be focussed where there are large numbers of migrants. Copyright © 2012 Elsevier Ltd. All rights reserved.

We identified the level and type of program collaboration and service integration (PCSI) among HIV prevention programs in 59 CDC-funded health department jurisdictions. Annual progress reports (APRs) completed by all 59 health departments funded by CDC for HIV prevention activities were reviewed for collaborative and integrated activities reported by HIV programs for calendar year 2009. We identified associations between PCSI activities and funding, AIDS diagnosis rate, and organizational integration. HIV programs collaborated with other health department programs through data-related activities, provider training, and providing funding for sexually transmitted disease (STD) activities in 24 (41%), 31 (53%), and 16 (27%) jurisdictions, respectively. Of the 59 jurisdictions, 57 (97%) reported integrated HIV and STD testing at the same venue, 39 (66%) reported integrated HIV and tuberculosis testing, and 26 (44%) reported integrated HIV and viral hepatitis testing. Forty-five (76%) jurisdictions reported providing integrated education/outreach activities for HIV and at least one other disease. Twenty-six (44%) jurisdictions reported integrated partner services among HIV and STD programs. Overall, the level of PCSI activities was not associated with HIV funding, AIDS diagnoses, or organizational integration. HIV programs in health departments collaborate primarily with STD programs. Key PCSI activities include integrated testing, integrated education/outreach, and training. Future assessments are needed to evaluate PCSI activities and to identify the level of collaboration and integration among prevention programs.

Cervical cancer is a leading cause of mortality in Sub-Saharan Africa-in large part because of inadequate coverage of screening and preventive treatment services. A number of programs have begun integrating cervical cancer prevention services into existing family planning or HIV/AIDS service delivery platforms, to rapidly expand "screen and treat" programs and mitigate cervical cancer burden. Drawing upon a review of literature and our experiences, we consider benefits and challenges associated with such programs in Sub-Saharan Africa. We then outline steps that can optimize uptake and sustainability of integrated sexual and reproductive health services. These include increasing coordination among implementing organizations for efficient use of resources; task shifting for services that can be provided by nonphysicians; mobilizing communities via trusted frontline health workers; strengthening management information systems to allow for monitoring of multiple services; and prioritizing an operational research agenda to provide further evidence on the cost-effectiveness and benefits of integrated service delivery. © 2017 The Authors.

The presence of asymptomatic eosinophilia in HIV patients has been demonstrated to have a wide variety of causes. Untreated parasitic infections in immunocompromised individuals can have potentially serious consequences. The utility of screening for parasitic infections in immigrant HIV-positive Africans with eosinophilia was investigated in a UK-based HIV clinic. HIV-positive African patients with eosinophilia were matched with HIV-positive African controls without eosinophilia. More than half of African HIV patients with eosinophilia had positive parasitic serology, and were significantly more likely to have positive serology compared with African HIV patients without eosinophilia. This study shows that asymptomatic eosinophilia in HIV-1-infected Africans is strongly suggestive of underlying parasitic infection. Individuals with eosinophilia should thus be screened for parasitic infections according to the infections prevalent in the countries they have lived in or visited for substantial periods of time.

Full Text Available BACKGROUND: Co-infection with hepatitis B virus (HBV is highly prevalent in people living with HIV in Sub-Saharan Africa. Screening for HBV surface antigen (HBsAg before initiation of combination antiretroviral therapy (cART is recommended. However, it is not part of diagnostic routines in HIV programs in many resource-limited countries although patients could benefit from optimized antiretroviral therapy covering both infections. Screening could be facilitated by rapid diagnostic tests for HBsAg. Operating experience with these point of care devices in HIV-positive patients in Sub-Saharan Africa is largely lacking. We determined the prevalence of HBV and Hepatitis C virus (HCV infection as well as the diagnostic accuracy of the rapid test device Determine HBsAg in an HIV cohort in rural Tanzania. METHODS: Prospectively collected blood samples from adult, HIV-1 positive and antiretroviral treatment-naïve patients in the Kilombero and Ulanga antiretroviral cohort (KIULARCO in rural Tanzania were analyzed at the point of care with Determine HBsAg, a reference HBsAg EIA and an anti-HCV EIA. RESULTS: Samples of 272 patients were included. Median age was 38 years (interquartile range [IQR] 32-47, 169/272 (63% subjects were females and median CD4+ count was 250 cells/µL (IQR 97-439. HBsAg was detected in 25/272 (9.2%, 95% confidence interval [CI] 6.2-13.0% subjects. Of these, 7/25 (28% were positive for HBeAg. Sensitivity of Determine HBsAg was rated at 96% (95% CI 82.8-99.6% and specificity at 100% (95% CI, 98.9-100%. Antibodies to HCV (anti-HCV were found in 10/272 (3.7%, 95% CI 2.0-6.4% of patients. CONCLUSION: This study reports a high prevalence of HBV in HIV-positive patients in a rural Tanzanian setting. The rapid diagnostic test Determine HBsAg is an accurate assay for screening for HBsAg in HIV-1 infected patients at the point of care and may further help to guide cART in Sub-Saharan Africa.

Full Text Available 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%. All 16 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.

CD4(+) cell count, the common HIV infection screening test, is costly and unable to differentiate HIV monoinfection from its concurrent infection with hepatitis B or C virus. We aimed to ascertain diagnostic value of serum adenosine deaminase (ADA) activity as a useful tool to differentiate HIV mono- and co-infection. Blood samples were collected from 30 HIV-HBV and 30 HIV-HCV coinfected patients, 33 HIV positive subjects, and 72 controls. CD4(+) cell count, serum total ADA (tADA), and ADA1, and ADA2 isoenzyme activities were determined and their sensitivity and specificity were computed. tADA and ADA2 activities were significantly higher and CD4(+) counts were markedly lower in all patients compared with controls. Strong inverse agreements between CD4(+) cell counts and both tADA and ADA2 activities were observed. Serum tADA and ADA1 activities showed the highest specificity and the highest sensitivity, respectively, for differentiating HIV monoinfection from HIV-HBV and HIV-HCV coinfections. We showed strong agreement and correlation between CD4(+) cell count and ADA enzyme activity. Based on high ADA sensitivity and specificity, it is concluded that determination of ADA activity might be a novel diagnostic tool to distinguish of HIV monoinfection from its coinfection with HBV or HCV. © 2015 Wiley Periodicals, Inc.

Traumatic events can negatively affect clinical outcomes among HIV positive women, particularly when those events result in ongoing psychological distress. Consequently, there have been calls to integrate screening and treatment of traumatic experiences and associated mental health disorders into HIV care. In South Africa, screening for traumatic experiences and mental health is not a routine part of HIV care. The goal of this study was to examine the prevalence of traumatic experiences and mental health distress among women in an HIV clinic in Cape Town, South Africa, and to explore the acceptability of routine screening in this setting. Seventy HIV positive women were screened following referral from health care workers in the clinic. Among the participants, 51% reported a history of sexual abuse and 75% reported physical intimate partner violence (physical IPV). Among all participants, 36% met screening criteria for depression; among those with traumatic experiences ( n = 57), 70% met screening criteria for posttraumatic stress disorder (PTSD). Compared with reporting no sexual abuse or physical IPV, having experienced both sexual abuse and physical IPV was significantly associated with higher odds of depression, while reporting either sexual abuse or physical IPV individually was not significantly associated with increased odds of depression. Among women reporting sexual abuse, 61% were disclosing their experience for the first time during the screening; 31% of women with physical IPV experience were disclosing for the first time. Overall, 98% of participants thought screening should be routine and extended to all women as part of clinic care. Screening women for sexual abuse and physical IPV may be an important component of ensuring HIV care engagement.

Full Text Available Newark, New Jersey, is disproportionally affected by HIV with one of the highest prevalence rates in the United States. Rutgers New Jersey Medical School is a major healthcare provider to Newark’s underserved population and has implemented a HIV testing program that can diagnose and link newly diagnosed individuals to care. We conducted a retrospective chart review of all new patients seen in the Infectious Disease Practice from January 1, 2013, to December 31, 2014, to determine the proportion of patients with a missed testing opportunity (MTO (patients with a new HIV diagnosis with an encounter at the institution in the 1 year prior to their first appointment. 117 newly diagnosed patients were identified. 36 (31% had at least one MTO. A total of 34 (29% of newly diagnosed patients had AIDS at presentation and 17% had CD4 counts of 50 cells/μL (p value 0.5. The two most common locations of a missed testing opportunity were the hospital ED (45% and subspecialty clinics (37%. This study demonstrates that, even in a high prevalence institution with HIV counseling, testing, and referral service, HIV screening is lacking at multiple points of care and patients are missing opportunities for earlier diagnosis and treatment.

Full Text Available Abstract Background Cervical Cancer (CC is the number one cancer among women in sub-Saharan Africa. Although CC is preventable, most women in developing countries do not have access to screening. Methods This cross-sectional study was conducted to determine the prevalence and risk factors for cervical lesions using visual inspection with acetic acid (VIA among 112 HIV positive and 161 negative women aged 18–69 years. Results The presence of cervical lesions was greater among HIV positive (22.9% than HIV negative women (5.7%; p < 0.0001. In logistic models, the risk of cervical lesions among HIV positive women was 5.24 times higher when adjusted by age (OR 5.24, CI 2.31–11.88, and 4.06 times higher in a full model (OR 4.06, CI 1.61–10.25, than among HIV negative women. In the age-adjusted model women who had ≥2 lifetime sexual partners were 3 times more likely (OR 3.00, CI 1.02–8.85 to have cervical lesions compared to women with one lifetime partner and the odds of cervical lesions among women with a history of STIs were 2.16 greater (OR 2.16, CI 1.04–4.50 than among women with no previous STI. In the fully adjusted model women who had a previous cervical exam were 2.5 times more likely (OR 2.53, CI 1.06–6.05 to have cervical lesions than women who had not. Conclusions The high prevalence of HIV infection and the strong association between HIV and cervical lesions highlight the need for substantial scale-up of cervical screening to decrease the rate of CC in Swaziland.

Among people living with HIV, the proportion of deaths attributed to chronic noninfectious comorbid diseases has increased over the past 15 years. This is partly a result of increased longevity in the era of highly active antiretroviral therapy (HAART), and also because HIV infection is related, causally or otherwise, to several chronic conditions. These comorbidities include conditions that are strongly associated with modifiable risk factors, such as cardiovascular disease (CVD), diabetes, and renal and bone diseases, and increasingly management guidelines for HIV recommend risk evaluation for these conditions. The uptake of these screening approaches is often limited by the resources required for their application, and hence the management of risk reduction in most HIV-infected populations falls below a reasonable standard. The situation is compounded by the fact that few risk calculators have been adjusted for specific use in HIV infection. There is substantial overlap of risk factors for the four common comorbid diseases listed above that are especially relevant in HIV infection, and this offers an opportunity to develop a simple screening approach that encompasses the key risk factors for lifestyle-related chronic disease in people with HIV infection. This would identify those patients who require more in-depth investigation, and facilitate a stepwise approach to targeted management. Such a tool could improve communication between patient and clinician. A significant proportion of people with HIV are sufficiently engaged with their care to participate in health promotion and take the lead in using patient-centric screening measures. Health-based social networking offers a mechanism for dissemination of such a tool and is able to embed educational messages and support within the process. © 2012 British HIV Association.

There is limited information on the impact of the HIV/AIDS epidemic on Latino migrant workers (LMWs), although available data indicate that this community is being disproportionally affected. The need for prevention programs that address the specific needs of LMWs is becoming well recognized. HIV prevention interventions that train and employ community health workers are a culturally appropriate way to address the issues of community trust and capacity building in this community. This article describes the Latino Migrant Worker HIV Prevention Program and its efforts to train and engage community health workers in the prevention of HIV among LMWs in South Florida.

A whole genome screen for HIV restriction factors

2011-11-01

Full Text Available Abstract Background Upon cellular entry retroviruses must avoid innate restriction factors produced by the host cell. For human immunodeficiency virus (HIV human restriction factors, APOBEC3 (apolipoprotein-B-mRNA-editing-enzyme, p21 and tetherin are well characterised. Results To identify intrinsic resistance factors to HIV-1 replication we screened 19,121 human genes and identified 114 factors with significant inhibition of infection. Those with a known function are involved in a broad spectrum of cellular processes including receptor signalling, vesicle trafficking, transcription, apoptosis, cross-nuclear membrane transport, meiosis, DNA damage repair, ubiquitination and RNA processing. We focused on the PAF1 complex which has been previously implicated in gene transcription, cell cycle control and mRNA surveillance. Knockdown of all members of the PAF1 family of proteins enhanced HIV-1 reverse transcription and integration of provirus. Over-expression of PAF1 in host cells renders them refractory to HIV-1. Simian Immunodeficiency Viruses and HIV-2 are also restricted in PAF1 expressing cells. PAF1 is expressed in primary monocytes, macrophages and T-lymphocytes and we demonstrate strong activity in MonoMac1, a monocyte cell line. Conclusions We propose that the PAF1c establishes an anti-viral state to prevent infection by incoming retroviruses. This previously unrecognised mechanism of restriction could have implications for invasion of cells by any pathogen.

Validated data regarding HIV-transmission in prisons in developing countries is scarce. We examined sexual and injecting drug use behavior and HIV and HCV transmission in an Indonesian narcotic prison during the implementation of an HIV prevention and treatment program during 2004-2007 when the Banceuy Narcotic Prison in Indonesia conducted an HIV transmission prevention program to provide 1) HIV education, 2) voluntary HIV testing and counseling, 3) condom supply, 4) prevention of rape and sexual violence, 5) antiretroviral treatment for HIV-positive prisoners and 6) methadone maintenance treatment. During a first survey that was conducted between 2007 and 2009, new prisoners entered Banceuy Narcotics Prison were voluntary tested for HIV and HCV-infection after written informed consent was obtained. Information regarding sexual and injecting risk behavior and physical status were also recorded at admission to the prison. Participants who tested negative for both HIV and HCV during the first survey were included in a second survey conducted during 2008-2011. During both surveys, data on mortality among HIV-seropositive patients were also recorded. All HIV-seropositive participants receive treatment for HIV. HIV/ AIDS-related deaths decreased: 43% in 2006, 18% in 2007, 9% in 2008 and 0% in 2009. No HIV and HCV seroconversion inside Banceuy Narcotic Prison were found after a median of 23 months imprisonment (maximum follow-up: 38 months). Total of 484.8 person-years observation was done. Participants reported HIV transmission risk-behavior in Banceuy Prison during the second survey was low. After implementation of HIV prevention and treatment program, no new HIV or HCV cases were detected and HIV-related mortality decreased.

Full Text Available OBJECTIVE: In 1998, the Brazilian Ministry of Health made it mandatory for all blood banks in the country to screen donated blood for human immunodeficiency virus (HIV concomitantly using two different enzyme immunoassay (EIA tests. Concerned with the best use of available resources, our objective with this study was to evaluate the usefulness of conducting two EIA screening tests instead of just one. METHODS: We analyzed data from 1999 through 2001 obtained by testing 698 191 units of donated blood using two EIA HIV screening tests concomitantly at the Pro-Blood Foundation/Blood Center of São Paulo (Fundação Pró-Sangue/Hemocentro de São Paulo, which is a major blood center in the city of São Paulo, Brazil. All samples reactive in at least one of the two EIA tests were submitted for confirmation by a Western blot (WB test, and the persons who had donated those samples were also asked to return and provide a follow-up sample. RESULTS: Out of the 698 191 blood units that were donated, 2 718 of them (0.4% had to be discarded because they were reactive to at least one of the EIA tests. There were two WB-positive donation samples that were reactive in only one HIV EIA screening test. On their follow-up samples, both donors tested WB-negative. These cases were considered false positive results at screening. Of the 2 718 donors who were asked to return and provide a follow-up sample, 1 576 of them (58% did so. From these 1 576 persons, we found that there were two individuals who had been reactive to only one of the two EIA screening tests and who had also been negative on the WB at screening but who were fully seroconverted on the follow-up sample. We thus estimated that, in comparison to the use of a single EIA screening test, the use of two EIA screening tests would detect only one extra sample out of 410 700 units of blood. CONCLUSIONS: Our data do not support the use of two different, concomitant EIA screening tests for HIV. The great

Full Text Available Objectives To evaluate efficacy of the antenatal, intra-partum and post-natal antiretroviral components of a public service Prevention of Mother to Child (MTCT program in infants. Design Analysis of prospectively collected screening data of demographic and MTCT-related interventions and HIV-infection status of infants identified through HIV-specific DNA polymerase chain reaction. Setting Tygerberg Children’s Hospital, Western Cape Province, South Africa. Subjects HIV-infected women and their infants identified through participation in a public service MTCT program were referred for possible participation in a prospective study of isoniazid prophylaxis. Interventions Key components of the Program include voluntary counselling and testing, zidovudine to the mother from between 28 and 34 weeks gestation and to the newborn infant for the first week, single dose nevirapine to the mother in labour and the newborn shortly after birth and free formula for 6 months. Main Outcome Measures Number and percentage of HIV-infected infants and extent of exposure to antenatal, intrapartum and post-natal antiretrovirals. Results Of 656 infants with a median age of 12.6 weeks, screened between April 1st 2005 through May 2006, 39 were HIV-infected giving a transmission rate of 5.9% (95% CI: 4.4% - 8.0%. Antenatal prophylaxis was significantly associated with reduced transmission (OR: 0.43 (95% CI: 0.21 - 0.94 as opposed to intrapartum and postpartum components (p=0.85 and p=0.84, respectively. In multivariable analysis the antenatal component remained significant (OR=0.40 (95% CI 0.19 - 0.90. Conclusions The antenatal phase is the most important antiretroviral component of the MTCT program, allowing most opportunity for intervention.

Full Text Available Objective. Women living with HIV are at increased risk of human papillomavirus (HPV infection, which can lead to cervical cancer. New guidelines recommend indefinite screening. The objective of this study is to describe cervical cancer screening practices and colposcopy results in a cohort of women living with HIV over age of 65 who were followed before the new guidelines. Comorbidities, sexually transmitted infections (STIs, and other risk factors were evaluated. Methods. We conducted a retrospective chart review on 75 women aged 65 or older living with HIV with at least one Pap smear. Results. The mean age of the cohort was 66.5 and at HIV diagnosis was 56. The majority of women were immunocompetent. 80% had serial Pap smears. Of these, 86% of 238 were negative or ASCUS. No women progressed to HSIL. 92% of colposcopies had negative or CIN I results. Three women were treated successfully for high-grade dysplasia. More than half of women had other STIs. 72% were screened for HPV; 50% were positive. Conclusion. The majority of women had negative and low-grade Pap smears. Questions remain regarding the utility of continued Pap screening and the added value of HPV testing in this unique population of older women living with HIV.

Optimal investment in a portfolio of HIV prevention programs.

Zaric, G S; Brandeau, M L

2001-01-01

In this article, the authors determine the optimal allocation of HIV prevention funds and investigate the impact of different allocation methods on health outcomes. The authors present a resource allocation model that can be used to determine the allocation of HIV prevention funds that maximizes quality-adjusted life years (or life years) gained or HIV infections averted in a population over a specified time horizon. They apply the model to determine the allocation of a limited budget among 3 types of HIV prevention programs in a population of injection drug users and nonusers: needle exchange programs, methadone maintenance treatment, and condom availability programs. For each prevention program, the authors estimate a production function that relates the amount invested to the associated change in risky behavior. The authors determine the optimal allocation of funds for both objective functions for a high-prevalence population and a low-prevalence population. They also consider the allocation of funds under several common rules of thumb that are used to allocate HIV prevention resources. It is shown that simpler allocation methods (e.g., allocation based on HIV incidence or notions of equity among population groups) may lead to alloctions that do not yield the maximum health benefit. The optimal allocation of HIV prevention funds in a population depends on HIV prevalence and incidence, the objective function, the production functions for the prevention programs, and other factors. Consideration of cost, equity, and social and political norms may be important when allocating HIV prevention funds. The model presented in this article can help decision makers determine the health consequences of different allocations of funds.

Standard HIV testing is done using serum or plasma. FDA approved ELISA to screen urine for IgG antibodies to HIV-1 in 1996. It is a simple, noninvasive test and is appropriate for developing countries where health care personnel may not be professionally trained or where clean needles for drawing blood may not always be available. 436 individuals with high-risk behavior and strong clinical suspicion of HIV infection were screened for IgG antibodies to HIV-1 in urine by ELISA. Urine HIV testing was performed by enzyme immunoassay, at the ongoing Voluntary Confidential Counseling and Testing Center (VCCTC) at a large tertiary care microbiology lab. The individuals enrolled for the study had high-risk exposure to the virus and majorities were from a state with a high incidence of HIV infection. In all individuals, both serum and urine were tested for IgG antibodies to HIV-1. Overall, 135 individuals (30.96%) were HIV-positive, of whom 96 (71%) had never previously tested positive; 87% of those who tested positive received their results, and most were referred for medical care. Sensitivity, specificity and predictive values of HIV-1 urine ELISA test kit were determined. Sensitivity was found to be 89.6%; 95% CI [82.9-94.0], specificity 97.3%; 95% CI [94.6-98.8], positive predictive value 93.8%; 95% CI [87.8-97.1] and negative predictive value 95.4%; 95% CI [92.3-97.4]. Efficiency, sensitivity, and specificity of the urine-based screening for HIV-1 test kits were excellent as compared to the reference test.

Full Text Available The World Health Organization (WHO 2010 guidelines for intensified tuberculosis (TB case finding (ICF among people living with HIV (PLHIV includes a recommendation that PLHIV receive routine TB screening. Since 2005, the Rwandan Ministry of Health has been using a five-question screening tool. Our study objective was to assess the operating characteristics of the tool designed to identify PLHIV with presumptive TB as measured against a composite reference standard, including bacteriologically confirmed TB.In a cross-sectional study, the TB screening tool was routinely administered at enrolment in outpatient HIV care and treatment services at seven public health facilities. From March to September 2011, study enrollees were examined for TB disease irrespective of TB screening outcome. The examination consisted of a chest radiograph (CXR, three sputum smears (SS, sputum culture (SC and polymerase chain reaction line-probe assay (Hain test. PLHIV were classified as having "laboratory-confirmed TB" with positive results on SS for acid-fast bacilli, SC on Lowenstein-Jensen medium, or a Hain test.Overall, 1,767 patients were enrolled and screened of which; 1,017 (57.6% were female, median age was 33 (IQR, 27-41, and median CD4+ cell count was 385 (IQR, 229-563 cells/mm3. Of the patients screened, 138 (7.8% were diagnosed with TB of which; 125 (90.5% were laboratory-confirmed pulmonary TB. Of 404 (22.9% patients who screened positive and 1,363 (77.1% who screened negative, 79 (19.5% and 59 (4.3%, respectively, were diagnosed with TB. For laboratory-confirmed TB, the tool had a sensitivity of 54.4% (95% CI 45.3-63.3, specificity of 79.5% (95% CI 77.5-81.5, PPV of 16.8% and NPV of 95.8%.TB prevalence among PLHIV newly enrolling into HIV care and treatment was 65 times greater than the overall population prevalence. However, the performance of the tool was poorer than the predicted performance of the WHO recommended TB screening questions.

The aim of this study was to determine the prevalence of syphilis and toxoplasmosis infection in pregnant women in the Central African Republic who were and were not HIV-infected, in the framework of HIV surveillance. This case-control study included 270 HIV(+) and 217 HIV(-) pregnant women among 4 750 women who attended prenatal-care clinics throughout the Central African Republic from November 2011 through January 2012. Blood specimens were collected and serological evidence of HIV1/2 was analyzed by ELISA1 and ELISA2. The Toxoplasma gondii antibody was detected with the Toxo-Hai Fumouze(®) diagnostic kit. A VDRL test was performed to screen for syphilis in all study participants. Of the 434 samples tested, 33 (7.60%) were positive for syphilis: 21 (9.7%) among HIV(+) and 12 (5.5%) among HIV(-) women (p = 0.1031); 221 (50.90%) were positive for toxoplasmosis: 117 (53.9%) among HIV(+) and 104 (47.9%) among HIV(-) women (p = 0, 2119). Coinfection with HIV, syphilis, and toxoplasmosis was found in 6.00%. No association was found between coinfection and age, parity, and residence area. The rate of syphilis infection was very high in pregnant women living in rural areas (ORcrude = 4.37; 95% CI = 2,11, 9.05). This study showed a high prevalence of toxoplasmosis and syphilis in pregnant women in the Central African Republic, regardless of their HIV infection status. Sexually transmitted infections (STIs) are common in pregnant women living in rural areas. It may be appropriate to include routine serological screening tests to determine of toxoplasmosis, syphilis and HIV in pregnant women in this country.

Lung cancer screening may benefit HIV-infected (HIV) smokers because of an elevated risk of lung cancer, but may have unique harms because of HIV-specific risk factors for false-positive screens. This study seeks to understand whether inflammatory biomarkers and markers of chronic lung disease are associated with noncalcified nodules at least 4 mm (NCN) in HIV compared with uninfected patients. This is a cohort study of Examinations of HIV-Associated Lung Emphysema (EXHALE), including 158 HIV and 133 HIV-uninfected participants. Participants underwent a laboratory assessment [including measurement of D-dimer, interleukin 6, and soluble CD14 (sCD14)], chest computed tomography (CT), and pulmonary function testing. We created multivariable logistic regression models to determine predictors of NCN in the participants stratified by HIV status, with attention to semiqualitative scoring of radiographic emphysema, markers of pulmonary function, and inflammatory biomarkers. Of the 291 participants, 69 had NCN on chest CT. As previously reported, there was no difference in prevalence of these nodules by HIV status. Emphysema and elevated sCD14 demonstrated an association with NCN in HIV participants independent of smoking status, CD4 cell count, HIV viral load, and pulmonary function. Emphysema and sCD14, a marker of immune activation, was associated with a higher prevalence of NCN on chest CT in HIV participants. Patients with chronic immune activation and emphysema may be at higher risk for both false-positive findings and incident lung cancer, thus screening in this group requires further study to understand the balance of benefits and harms.

The authors propose their screening program for detection of breast cancer. It includes the entire complex of present-day screening diagnostic methods, starting from an original system for the formation of groups at risk of breast cancer and completed by the direct diagnostic model of detection of the condition, oriented at a differentiated approach to the use of mammographic techniques. The proposed organizational and methodologic screening measures are both economic and diagnostically effective, thus meeting the principal requirements to screening programs. Screening of 8541 risk-groups patients helped detect 867 nodular formations, 244 of which were cancer and 623 benign formations. 8 refs., 3 figs.,

Innovation in HIV prevention: organizational and intervention characteristics affecting program adoption.

Miller, R L

2001-08-01

A multiple case study design was used to explore the organizational characteristics of community-based organizations that provide HIV prevention programs and the criteria these organizations employ when judging the merits of externally-developed HIV prevention programs. In-depth interviews were conducted with organizational representatives of 38 randomly-selected HIV prevention providers throughout Illinois. Results indicated that there were three main types of adopting organizations: adopters of entire programs, adopters of program components and practices, and adopters of common ideas. These three types of organizations were distinguished by their level of organizational commitment to HIV prevention, organizational resources, and level of organizational maturity. Narrative data from the interviews are used to describe the dimensions that underlie the organizations' program adoption criteria. The criteria of merit used by these organizations to evaluate prevention programs provide partial empirical support for existing theories of technology transfer. Implications for designing and disseminating HIV prevention programs are discussed.

Screening for nonalcoholic steatohepatitis by using cytokeratin 18 and transient elastography in HIV mono-infection.

Full Text Available HIV-infected individuals are at high risk of developing nonalcoholic steatohepatitis (NASH, a leading cause of end-stage liver disease in Western countries. Nonetheless, due to the invasiveness of liver biopsy, NASH remains poorly understood in HIV mono-infection. We aimed to characterize the prevalence and predictors of NASH in unselected HIV mono-infected patients by means of non-invasive diagnostic tools.HIV-infected adults without significant alcohol intake or co-infection with hepatitis B or C underwent a routine screening program employing transient elastography (TE with controlled attenuation parameter (CAP and the serum biomarker cytokeratin-18 (CK-18. NASH was diagnosed non-invasively as the coexistence of fatty liver (CAP ≥248 dB/m and CK-18 >246 U/L. Identified cases of NASH were offered a diagnostic liver biopsy. Predictors of NASH were determined by multivariate logistic regression analysis.202 consecutive HIV mono-infected patients were included. NASH was non-invasively diagnosed in 23 cases (11.4%. Among them, 17 underwent a liver biopsy, and histology confirmed NASH in all cases. The prevalence of NASH was higher in patients with hypertriglyceridemia (17.1%, insulin resistance defined by homeostasis model for assessment of insulin resistance (HOMA-IR (25%, those with detectable HIV viral load (42.9% and those with elevated ALT (53.6%. After adjustment, higher HOMA-IR (adjusted odds ratio [aOR] = 1.20, 95% CI 1.01-1.43; p = 0.03 and ALT (aOR = 2.39, 95% CI 1.50-3.79; p<0.001 were independent predictors of NASH.NASH, diagnosed by a non-invasive diagnostic approach employing CK-18 and TE with CAP, is common in unselected HIV mono-infected individuals, particularly in the presence of insulin resistance and elevated ALT.

Investments in community-based HIV prevention programs in Ontario over the past two and a half decades are assumed to have had an impact on the HIV epidemic, but they have never been systematically evaluated. To help close this knowledge gap, we conducted a macro-level evaluation of investment in Ontario HIV prevention programs from the payer perspective. Our results showed that, from 1987 to 2011, province-wide community-based programs helped to avert a total of 16,672 HIV infections, saving Ontario's health care system approximately $6.5 billion Canadian dollars (range 4.8-7.5B). We also showed that these community-based HIV programs were cost-saving: from 2005 to 2011, every dollar invested in these programs saved about $5. This study is an important first step in understanding the impact of investing in community-based HIV prevention programs in Ontario and recognizing the impact that these programs have had in reducing HIV infections and health care costs.

Evaluation of a workplace hemochromatosis screening program.

Stave, G M; Mignogna, J J; Powell, G S; Hunt, C M

1999-05-01

Hemochromatosis is a common inherited disorder of iron metabolism with significant health consequences for the employed population. Although screening for hemochromatosis has been recommended, workplace screening programs remain uncommon. In the first year of a newly initiated corporate screening program, 1968 employees were tested. The screening algorithm included measurement of serum iron and transferrin and subsequent ferritin levels in those employees with elevated iron/transferrin ratios. Thirteen percent of men and 21% of women had elevated iron/transferrin ratios. Of these, 14 men and 2 women had elevated ferritin levels. Of these 16, three had liver biopsies and all three have hemochromatosis. The cost of the screening program was $27,850. The cost per diagnosis was $9283 and the cost per year of life saved was $928. These costs compare very favorably with other common workplace screening programs. Several barriers to obtaining definitive diagnoses on all patients with a positive screening result were identified; strategies to overcome these barriers would further enhance the cost effectiveness of the program. We conclude that workplace hemochromatosis screening is highly cost effective and should be incorporated into health promotion/disease prevention programs.

National HIV preventive programs in Mexico focus on high-risk groups that do not consider women, apart from prenatal screening. Nonetheless, the epidemic in women is growing, and there is a need to better understand sociodemographic factors in women living with HIV (WLH). We performed a case-control study in Mexico City, including HIV+ and HIV- women with a recent pregnancy to compare their sociodemographic characteristics and describe the circumstances of diagnosis in HIV+ women, as well as prenatal screening frequency in both groups. Fifty cases and 102 controls were interviewed. HIV+ women were more frequently the only economic support of the family (20% vs 0%, P history of sexually transmitted diseases, substance abuse, history of violence, and civil status. Only 6% of controls were tested for HIV during prenatal follow-up. WLH in this study faced important social vulnerability. Targeting women living in these social contexts might increase early diagnosis and could tailor HIV prevention strategies. Prenatal coverage needs to be improved and should represent a national priority.

HIV pre-exposure prophylaxis has been proven to be an effective tool in HIV prevention. However, numerous barriers still exist in pre-exposure prophylaxis implementation. The framework of Intervention Mapping was used from August 2016 to October 2017 to describe the process of adoption, implementation, and maintenance of an HIV prevention program from 2012 through 2017 in Houston, Texas, that is nested within a county health system HIV clinic. Using the tasks outlined in the Intervention Mapping framework, potential program implementers were identified, outcomes and performance objectives established, matrices of change objectives created, and methods and practical applications formed. Results include the formation of three matrices that document program outcomes, change agents involved in the process, and the determinants needed to facilitate program adoption, implementation, and maintenance. Key features that facilitated successful program adoption and implementation were obtaining leadership buy-in, leveraging existing resources, systematic evaluation of operations, ongoing education for both clinical and nonclinical staff, and attention to emergent issues during launch. The utilization of Intervention Mapping to delineate the program planning steps can provide a model for pre-exposure prophylaxis implementation in other settings. Copyright © 2018.

Maniewski, Ula; Payen, Marie-Christine; Delforge, Marc; De Wit, Stephane

2017-08-01

A decreasing incidence of tuberculosis (TB) among HIV patients has been documented in high-income settings and screening for tuberculosis is not systematically performed in many clinics (such as ours). Our objectives are to evaluate whether a same decline of incidence was seen in our Belgian tertiary center and to evaluate whether systematic screening and prophylaxis of tuberculosis should remain part of routine practice. Between 2005 and 2012, the annual incidence of tuberculosis among adult HIV patients was measured. The impact of demographic characteristics and CD 4 nadir on the incidence of active TB was evaluated. Among the 1167 patients who entered the cohort, 42 developed active TB with a significant decrease of annual incidence from 28/1000 patient-years in 2005 to 3/1000 patient-years in 2012. Among the 42 cases, 83% were of sub-Saharan origin. Median CD4 cell count upon HIV diagnosis was significantly lower in TB cases and 60% had a nadir CD4 below 200/μl. Thirty-six percent of incident TB occurred within 14 days after HIV diagnosis. A significant decline of TB incidence in HIV patients was observed. Incident TB occurred mainly in African patients, with low CD4 upon HIV diagnosis. A significant proportion of TB cases were discovered early in follow-up which probably reflects TB already present upon HIV diagnosis. In a low endemic setting, exclusion of active TB upon HIV diagnosis remains a priority and screening for LTBI should focus on HIV patients from high risk groups such as migrants from endemic regions, especially in patients with low CD4 nadir.

Early HIV diagnosis reduces morbidity, mortality, the probability of onward transmission, and their associated costs, but might increase cost because of earlier initiation of antiretroviral treatment (ART). We investigated this trade-off by estimating the cost-effectiveness of HIV screening in primary care. We modelled the effect of the four-times higher diagnosis rate observed in the intervention arm of the RHIVA2 randomised controlled trial done in Hackney, London (UK), a borough with high HIV prevalence (≥0·2% adult prevalence). We constructed a dynamic, compartmental model representing incidence of infection and the effect of screening for HIV in general practices in Hackney. We assessed cost-effectiveness of the RHIVA2 trial by fitting model diagnosis rates to the trial data, parameterising with epidemiological and behavioural data from the literature when required, using trial testing costs and projecting future costs of treatment. Over a 40 year time horizon, incremental cost-effectiveness ratios were £22 201 (95% credible interval 12 662-132 452) per quality-adjusted life-year (QALY) gained, £372 207 (268 162-1 903 385) per death averted, and £628 874 (434 902-4 740 724) per HIV transmission averted. Under this model scenario, with UK cost data, RHIVA2 would reach the upper National Institute for Health and Care Excellence cost-effectiveness threshold (about £30 000 per QALY gained) after 33 years. Scenarios using cost data from Canada (which indicate prolonged and even higher health-care costs for patients diagnosed late) suggest this threshold could be reached in as little as 13 years. Screening for HIV in primary care has important public health benefits as well as clinical benefits. We predict it to be cost-effective in the UK in the medium term. However, this intervention might be cost-effective far sooner, and even cost-saving, in settings where long-term health-care costs of late-diagnosed patients in high

Women living with HIV (WHIV) are disproportionately impacted by cervical dysplasia and cancer. The burden is greatest in low-income countries where limited or no access to screening exists. The goal of this study was to describe knowledge and intentions of WHIV towards HPV self-collection for cervical cancer screening, and to report on factors related to HPV positivity among women who participated in testing. A validated survey was administered to 87 HIV positive women attending the Kisenyi Health Unit aged 30-69 years old, and data was abstracted from chart review. At a later date, self-collection based HPV testing was offered to all women. Specimens were tested for high risk HPV genotypes, and women were contacted with results and referred for care. Descriptive statistics, Chi Square and Fischer-exact statistical tests were performed. The vast majority of WHIV (98.9%) women did not think it necessary to be screened for cervical cancer and the majority of women had never heard of HPV (96.4%). However, almost all WHIV found self-collection for cervical cancer screening to be acceptable. Of the 87 WHIV offered self-collection, 40 women agreed to provide a sample at the HIV clinic. Among women tested, 45% were oncogenic HPV positive, where HPV 16 or 18 positivity was 15% overall. In this group of WHIV engaged in HIV care, there was a high prevalence of oncogenic HPV, a large proportion of which were HPV genotypes 16 or 18, in addition to low knowledge of HPV and cervical cancer screening. Improved education and cervical cancer screening for WHIV are sorely needed; self-collection based screening has the potential to be integrated with routine HIV care in this setting.

Fischer, P M; Guinan, K H; Burke, J J; Karp, W B; Richards, J W

1990-12-01

The National Cholesterol Education Program (NCEP) has endorsed physician case finding as the primary method to detect individuals with elevated cholesterol levels. Despite this recommendation, promotional and for-profit public screening programs have flourished. We surveyed participants of a mall-based cholesterol screening program 1 year after their screening. Sixty-four percent of those screened had not previously known their cholesterol levels. Those who were newly screened were less likely to benefit from this testing than the general public, since they were older (mean age, 55.3 years), more likely to be female (67.4%), and nonsmokers (88%). Screenees had excellent recall of their cholesterol level (mean absolute reporting error, 0.24 mmol/L [9 mg/dL]) and a good understanding of cholesterol as a coronary heart disease risk. Those with elevated cholesterol levels reported high distress from screening but no reduction in overall psychosocial well-being and an actual decrease in absenteeism. Only 53.7% of all who were advised to seek follow-up because of an elevated screening value had done so within the year following the screening program. However, of those with values greater than 6.2 mmol/L (240 mg/dL), 68% had sought follow-up. Many of those who participate in public screening programs have been previously tested, fall into low-benefit groups, or fail to comply with recommended follow-up. We therefore conclude that cholesterol screening programs of the type now commonly offered are unlikely to contribute greatly to the national efforts to further reduce coronary heart disease.

BACKGROUND: The routine offering of testing for HIV during each pregnancy is recommended by various advisory bodies, including the Canadian Paediatric Society. OBJECTIVES: To determine the proportion of women in Nova Scotia who were counselled about HIV and HIV testing during their pregnancies and to determine the proportion of those who underwent the blood test after counselling. METHODS: A Self-administered survey at the IWK Health Centre, Halifax, Nova Scotia was performed. Questionnaires were distributed to 800 new mothers who delivered a child between March 10 and May 10, 2000. The questionnaire asked women for their ages, levels of education, history of previous deliveries, whether they had received counselling about HIV during their pregnancy, whether they were offered an HIV blood test and whether they underwent an HIV blood test. RESULTS: A total of 155 questionnaires were returned (response rate of 19.4%). The proportion of women who were counselled about HIV during their pregnancy was 65 of 155 (41.9%) (95% CI 34.1 to 49.7) and the proportion of those who were counselled who underwent the test was 47 of 65 (72.3%) (95% CI 65.3 to 79.3). There was a significant difference between the proportion counselled and history of previous deliveries (P=0.050), the proportion offered a test and their ages (P=0.028), and the proportion who had a test done and their ages (P=0.017). CONCLUSIONS: There is inadequate compliance with the recommendation that all women be offered HIV testing during each pregnancy at the IWK Health Centre. Health care professionals involved in obstetrics need to be reminded of the importance of HIV counselling and testing during pregnancy. Further evaluation throughout Canada of the effect of HIV screening recommendations during pregnancy is advisable. PMID:20046277

Considerable scope exists to vary the physical and chemical properties of nanoparticles, with subsequent impact on biological interactions; however, no accelerated process to access large nanoparticle material space is currently available, hampering the development of new nanomedicines. In particular, no clinically available nanotherapies exist for HIV populations and conventional paediatric HIV medicines are poorly available; one current paediatric formulation utilizes high ethanol concentrations to solubilize lopinavir, a poorly soluble antiretroviral. Here we apply accelerated nanomedicine discovery to generate a potential aqueous paediatric HIV nanotherapy, with clinical translation and regulatory approval for human evaluation. Our rapid small-scale screening approach yields large libraries of solid drug nanoparticles (160 individual components) targeting oral dose. Screening uses 1 mg of drug compound per library member and iterative pharmacological and chemical evaluation establishes potential candidates for progression through to clinical manufacture. The wide applicability of our strategy has implications for multiple therapy development programmes.

This retrospective study assessed whether Quality Improvement Scotland national standards for the sexual health care offered to HIV-positive individuals are being met by the Edinburgh genitourinary (GU) medicine clinic; specifically whether HIV-positive patients are offered: (a) sexually transmitted infection (STI) screening annually and (b) syphilis testing six-monthly. The study also reviewed what factors were associated with a clinician's offer of STI screening and syphilis testing. Of the 509 patients seen within the study period, case notes documented that 64% were offered STI screens, and 69% were offered syphilis testing, results consistent with audits of services elsewhere. Sexual orientation (P offer of STI screening, while gender (P offer of syphilis testing. Our results suggest that one explanation for clinicians failing to offer STI screens and syphilis serology testing is their (implicit) risk assessment that STI testing is not required in individual patients.

Full Text Available Abstract Background Despite progress in the development of combined antiretroviral therapies (cART, HIV infection remains a significant challenge for human health. Current problems of cART include multi-drug-resistant virus variants, long-term toxicity and enormous treatment costs. Therefore, the identification of novel effective drugs is urgently needed. Methods We developed a straightforward screening approach for simultaneously evaluating the sensitivity of multiple HIV gag-pol mutants to antiviral drugs in one assay. Our technique is based on multi-colour lentiviral self-inactivating (SIN LeGO vector technology. Results We demonstrated the successful use of this approach for screening compounds against up to four HIV gag-pol variants (wild-type and three mutants simultaneously. Importantly, the technique was adapted to Biosafety Level 1 conditions by utilising ecotropic pseudotypes. This allowed upscaling to a large-scale screening protocol exploited by pharmaceutical companies in a successful proof-of-concept experiment. Conclusions The technology developed here facilitates fast screening for anti-HIV activity of individual agents from large compound libraries. Although drugs targeting gag-pol variants were used here, our approach permits screening compounds that target several different, key cellular and viral functions of the HIV life-cycle. The modular principle of the method also allows the easy exchange of various mutations in HIV sequences. In conclusion, the methodology presented here provides a valuable new approach for the identification of novel anti-HIV drugs.

Two decades after its discovery the human immunodeficiency virus (HIV) is still spreading worldwide and killing millions. There are 25 drugs formally approved for HIV currently on the market, but side effects as well as the emergence of HIV strains showing single or multiple resistances to current drug-therapy are causes for concern. Furthermore, these drugs target only 4 steps of the viral cycle, hence the urgent need for new drugs and also new targets. In order to tackle this problem, we have devised a cell-based assay using lentiviral particles to look for post-entry inhibitors of HIV-1. We report here the assay development, validation as well as confirmation of the hits using both wild-type and drug-resistant HIV-1 viruses. The screening was performed on an original library, rich in natural compounds and pure molecules from Traditional Chinese Medicine pharmacopoeia, which had never been screened for anti-HIV activity. The identified hits belong to four chemical sub-families that appear to be all non-nucleoside reverse transcriptase inhibitors (NNRTIs). Secondary tests with live viruses showed that there was good agreement with pseudotyped particles, confirming the validity of this approach for high-throughput drug screens. This assay will be a useful tool that can be easily adapted to screen for inhibitors of viral entry.

Fieno, John; Leclerc-Madlala, Suzanne

2014-01-01

As the search for more effective HIV prevention strategies continues, increased attention is being paid to the potential role of cash transfers in prevention programming in sub-Saharan Africa. To date, studies testing the impact of both conditional and unconditional cash transfers on HIV-related behaviours and outcomes in sub-Saharan Africa have been relatively small-scale and their potential feasibility, costs and benefits at scale, among other things, remain largely unexplored. This article examines elements of a successful cash transfer program from Latin America and discusses challenges inherent in scaling-up such programs. The authors attempt a cost simulation of a cash transfer program for HIV prevention in South Africa comparing its cost and relative effectiveness--in number of HIV infections averted--against other prevention interventions. If a cash transfer program were to be taken to scale, the intervention would not have a substantial effect on decreasing the force of the epidemic in middle- and low-income countries. The integration of cash transfer programs into other sectors and linking them to a broader objective such as girls' educational attainment may be one way of addressing doubts raised by the authors regarding their value for HIV prevention.

In 2010, to reduce late HIV diagnosis, the French national health agency endorsed non-targeted HIV screening in health care settings. Despite these recommendations, non-targeted screening has not been implemented and only physician-directed diagnostic testing is currently performed. A survey conducted in 2010 in 29 French Emergency Departments (EDs) showed that non-targeted nurse-driven screening was feasible though only a few new HIV diagnoses were identified, predominantly among high-risk groups. A strategy targeting high-risk groups combined with current practice could be shown to be feasible, more efficient and cost-effective than current practice alone. DICI-VIH (acronym for nurse-driven targeted HIV screening) is a multicentre, cluster-randomized, two-period crossover trial. The primary objective is to compare the effectiveness of 2 strategies for diagnosing HIV among adult patients visiting EDs: nurse-driven targeted HIV screening combined with current practice (physician-directed diagnostic testing) versus current practice alone. Main secondary objectives are to compare access to specialist consultation and how early HIV diagnosis occurs in the course of the disease between the 2 groups, and to evaluate the implementation, acceptability and cost-effectiveness of nurse-driven targeted screening. The 2 strategies take place during 2 randomly assigned periods in 8 EDs of metropolitan Paris, where 42 % of France's new HIV patients are diagnosed every year. All patients aged 18 to 64, not presenting secondary to HIV exposure are included. During the intervention period, patients are invited to fill a 7-item questionnaire (country of birth, sexual partners and injection drug use) in order to select individuals who are offered a rapid test. If the rapid test is reactive, a follow-up visit with an infectious disease specialist is scheduled within 72 h. Assuming an 80 % statistical power and a 5 % type 1 error, with 1.04 and 3.38 new diagnoses per 10,000 patients in

New Zealand, which has a low incidence of tuberculosis (TB), has historically taken a risk-based approach to screening for latent tuberculous infection (LTBI) in adult people living with the human immunodeficiency virus infection (PLHIV). To evaluate LTBI screening, treatment and outcomes in an adult PLHIV population. This was a retrospective clinical record review of an initial cohort of adult PLHIV attending the Auckland City Hospital HIV clinic in 2011, and a second cohort of adult PLHIV newly attending the clinic in 2014. We analysed high-risk (born in or acquiring HIV in a high TB incidence country) and low-risk patients using descriptive statistical methods. Of the 752 patients from the initial cohort, 416 (55%) had documentation of LTBI screening, which was positive in 74 (10%): 19/461 (4%) low-risk and 55/291 (19%) high-risk patients. LTBI treatment was received in 13 low-risk and 44 high-risk patients. Of 73 patients in the second cohort, 68 (93%) were screened. LTBI screening was incomplete in our clinic, but improved between 2011 and 2014. A significant number of patients with LTBI did not originate from a high TB incidence country.

A Microfinance Program Targeting People Living with HIV in Uganda: Client Characteristics and Program Impact.

Linnemayr, Sebastian; Buzaalirwa, Lydia; Balya, James; Wagner, Glenn

HIV has disproportionately affected economically vulnerable populations. HIV medical care, including antiretroviral therapy, successfully restores physical health but can be insufficient to achieve social and economic health. It may therefore be necessary to offer innovative economic support programs such as providing business training and microcredit tailored to people living with HIV/AIDS. However, microfinance institutions have shown reluctance to reach out to HIV-infected individuals, resulting in nongovernment and HIV care organizations providing these services. The authors investigate the baseline characteristics of a sample of medically stable clients in HIV care who are eligible for microcredit loans and evaluate their business and financial needs; the authors also analyze their repayment pattern and how their socioeconomic status changes after receipt of the program. The authors find that there is a significant unmet need for business capital for the sample under investigation, pointing toward the potentially beneficial role of providing microfinance and business training for clients in HIV care. HIV clients participating in the loans show high rates of repayment, and significant increases in (disposable) income, as well as profits and savings. The authors therefore encourage other HIV care providers to consider providing their clients with such loans.

As an important target for the development of novel anti-AIDS drugs, HIV-1 integrase (IN) has been widely concerned. However, the lack of a complete accurate crystal structure of HIV-1 IN greatly blocks the discovery of novel inhibitors. In this work, an effective HIV-1 IN inhibitor screening platform, namely PFV IN, was filtered from all species of INs. Next, the 40.8% similarity with HIV-1 IN, as well as the high efficiency of virtual screening and the good agreement between calculated binding free energies and experimental ones all proved PFV IN is a promising screening platform for HIV-1 IN inhibitors. Then, the molecular recognition mechanism of PFV IN by its substrate viral DNA and six naphthyridine derivatives (NRDs) inhibitors was investigated through molecular docking, molecular dynamics simulations and water-mediated interactions analyses. The functional partition of NRDs IN inhibitors could be divided into hydrophobic and hydrophilic ones, and the Mg 2+ ions, water molecules and conserved DDE motif residues all interacted with the hydrophilic partition, while the bases in viral DNA and residues like Tyr212, Pro214 interacted with the hydrophobic one. Finally, the free energy landscape (FEL) and cluster analyses were performed to explore the molecular motion of PFV IN-DNA system. It is found that the association with NRDs inhibitors would obviously decrease the motion amplitude of PFV IN-DNA, which may be one of the most potential mechanisms of IN inhibitors. This work will provide a theoretical basis for the inhibitor design based on the structure of HIV-1 IN. Copyright © 2017 Elsevier Inc. All rights reserved.

Ten years after the Centers for Disease Control and Prevention recommended universal HIV screening, rates remain low. Internal medicine residents are the front-line medical providers for large groups of patients. We evaluated the knowledge of internal medicine residents about HIV testing guidelines and examined adherence to universal HIV testing in an outpatient setting. A cross-sectional survey of internal medicine residents at four residency programs in Chicago was conducted from January to March 2016. Aggregate data on HIV screening were collected from 35 federally qualified community health centers in the Chicago area after inclusion of an HIV testing best practice alert in patients' electronic medical records. Of the 192 residents surveyed, 130 (68%) completed the survey. Only 58% were aware of universal HIV screening and 49% were aware that Illinois law allows for an opt-out HIV testing strategy. Most of the residents (64%) ordered no more than 10 HIV tests in 6 months. The most frequently reported barriers to HIV testing were deferral because of urgent care issues, lack of time, and the perception that patients were uncomfortable discussing HIV testing. From July 2015 to February 2016, the average HIV testing adherence rate in the 35 health centers was 18.2%. More effort is needed to change HIV testing practices among internal medicine residents so that they will adopt this approach in their future clinical practice. Improving knowledge about HIV testing and addressing other HIV testing barriers are essential for such a successful change.

The multi-step process of building TB/HIV collaboration in Cambodia

Full Text Available Abstract Tuberculosis and HIV/AIDS have synergistic health impacts in terms of disease development and progression. Therefore, collaborative TB and HIV/AIDS activities are a logical health systems response. However, the establishment of these activities presents a challenge for countries that have strong vertical disease programs that differ in their implementation philosophies. Here, we review the process by which TB/HIV collaboration was established in Cambodia. A cycle of overlapping and mutually reinforcing initiatives – local research; piloted implementation with multiple options; and several rounds of policy formulation guided by a cross-functional Technical Working Group – was used to drive nationwide introduction of a full set of TB/HIV collaborative activities. Senior Ministry of Health officials and partner organizations brought early attention to TB/HIV. Both national programs implemented initial screening and testing interventions, even in the absence of a detailed, overarching framework. The use of multiple options for HIV testing identified which programmatic options worked best, and early implementation and pilots determined what unanswered questions required further research. Local conduct of this research – on co-treatment timing and TB symptom screening – speeded adoption of the results into policy guidance, and clarified the relative roles of the two programs. Roll-out is continuing, and results for a variety of key indicators, including screening PLHIV for TB, and testing TB patients for HIV, are at 70-80% and climbing. This experience in Cambodia illustrates the influence of health research on policy, and demonstrates that clear policy guidance, the pursuit of incremental advances, and the use of different approaches to generate evidence can overcome structural barriers to change and bring direct benefits to patients.

This study aimed to determine the prevalence of HIV neurocognitive impairment in HIV-infected men who have sex with men aged 18-50 years, using a simple battery of screening tests in routine clinical appointments. Those with suspected abnormalities were referred on for further assessment. The cohort was also followed up over time to look at evolving changes. HIV-infected participants were recruited at three clinical sites in London during from routine clinical visits. They could be clinician or self-referred and did not need to be symptomatic. They completed questionnaires on anxiety, depression, and memory. They were then screened using the Brief Neurocognitive Screen (BNCS) and International HIV Dementia Scale (IHDS). Two hundred and five HIV-infected subjects were recruited. Of these, 59 patients were excluded as having a mood disorder and two patients were excluded due to insufficient data, leaving 144 patients for analysis. One hundred and twenty-four (86.1%) had a normal composite z score (within 1 SD of mean) calculated for their scores on the three component tests of the BNCS. Twenty (13.9%) had an abnormal z score, of which seven (35%) were symptomatic and 13 (65%) asymptomatic. Current employment and previous educational level were significantly associated with BNCS scores. Of those referred onwards for diagnostic testing, only one participant was found to have impairment likely related to HIV infection. We were able to easily screen for mood disorders and cognitive impairment in routine clinical practice. We identified a high level of depression and anxiety in our cohort. Using simple screening tests in clinic and an onward referral process for further testing, we were not able to identify neurocognitive impairment in this cohort at levels consistent with published data.

The incidence of human immunodeficiency virus (HIV) infection in the United States is higher among persons with other sexually transmitted diseases (STDs), and the incidence of other STDs is increased among persons with HIV infection (1). Because infection with an STD increases the risk for HIV acquisition and transmission (1-4), successfully treating STDs might help reduce the spread of HIV among persons at high risk (1-4). Because health department STD programs provide services to populations who are at risk for HIV, ensuring service integration and coordination could potentially reduce the incidence of STDs and HIV. Program integration refers to the combining of STD and HIV prevention programs through structural, service, or policy-related changes such as combining funding streams, performing STD and HIV case matching, or integrating staff members (5). Some STD programs in U.S. health departments are partially or fully integrated with an HIV program (STD/HIV program), whereas other STD programs are completely separate. To assess the extent of provision of HIV services by state and local health department STD programs, CDC analyzed data from a sample of 311 local health departments and 56 state and directly funded city health departments derived from a national survey of STD programs. CDC found variation in the provision of HIV services by STD programs at the state and local levels. Overall, 73.1% of state health departments and 16.1% of local health departments matched STD case report data with HIV data to analyze possible syndemics (co-occurring epidemics that exacerbate the negative health effects of any of the diseases) and overlaps. Similarly, 94.1% of state health departments and 46.7% of local health departments performed site visits to HIV care providers to provide STD information or public health updates. One fourth of state health departments and 39.4% of local health departments provided HIV testing in nonclinical settings (field testing) for STD

This review provides international insights into the real-world clinical approach to screening for bone mineral density (BMD) and osteoporosis in people living with HIV (PLWH) using opinions from HIV physicians from key regions around the world. Although a significant proportion of PLWH are aged over 50, the relative importance of low BMD to clinical care differs significantly between countries and regions, based on factors such as the population at risk, access to adequate screening resources, and physicians' knowledge. Generally, management of osteoporosis in PLWH follows similar principals as for the general population, with risk factors for fracture combined with measurement of BMD by dual energy X-ray absorptiometry in algorithms such as Fracture Risk Assessment Tool, designed to provide an overall risk estimation. Although in most regions age is considered among the most important factors contributing to low BMD and fractures, considerable country and region-specific factors become apparent, such as malnutrition, inactivity and impact of comorbidities, substance abuse, and increasing use of tenofovir disoproxil fumarate. These opinions highlight the diversity that still exists in the approach to the long-term management of PLWH and highlight challenges facing development of consensus guidelines that can be effectively implemented worldwide.

Maharaj, Sonill S; Yakasai, Abdulsalam M

2018-05-01

Distal symmetrical polyneuropathy is a common neurological sequela after HIV, which leads to neuropathic pain and functional limitations. Rehabilitation programs with exercises are used to augment pharmacological therapy to relieve pain but appropriate and effective exercises are unknown. This study explored the safety and effect of moderate-intensity aerobic exercises and progressive resisted exercises for HIV-induced distal symmetrical polyneuropathy neuropathic pain. A randomized pretest, posttest of 12 wks of aerobic exercise or progressive resisted exercise compared with a control. Outcome measures were assessed using the subjective periphery neuropathy, brief peripheral neuropathy screening, and numeric pain rating scale. Pain was assessed at baseline, 6 and 12 wks. Data between groups were compared using Kruskal-Wallis, Mann-Whitney U test, and within-groups Friedman and Wilcoxon signed rank tests. There were 136 participants (mean [SD] age = 36.79 [8.23] yrs) and the exercise groups completed the protocols without any adverse effects. Pain scores within and between aerobic exercise and progressive resisted exercise groups showed significant improvement (P 0.05). This study supports a rehabilitation program of moderate-intensity aerobic exercise and progressive resisted exercise being safe and effective for reducing neuropathic pain and is beneficial with analgesics for HIV-induced distal symmetrical polyneuropathy.

Many practical clinical questions regarding the management of human immunodeficiency virus (HIV)–associated neurocognitive disorder (HAND) remain unanswered. We sought to identify and develop practical answers to key clinical questions in HAND management. Sixty-six specialists from 30 countries provided input into the program, which was overseen by a steering committee. Fourteen questions were rated as being of greatest clinical importance. Answers were drafted by an expert group based on a comprehensive literature review. Sixty-three experts convened to determine consensus and level of evidence for the answers. Consensus was reached on all answers. For instance, good practice suggests that all HIV patients should be screened for HAND early in disease using standardized tools. Follow-up frequency depends on whether HAND is already present or whether clinical data suggest risk for developing HAND. Worsening neurocognitive impairment may trigger consideration of antiretroviral modification when other causes have been excluded. The Mind Exchange program provides practical guidance in the diagnosis, monitoring, and treatment of HAND. PMID:23175555

Full Text Available Waria or transgender is one of the key population which has a significant role in the success of HIV/AIDS prevention program in East Java. It is estimated that the biggest waria community is in East Java, particularly in Surabaya. The main objective of this research is improving capacity building of ludruk artist waria through HIV/AIDS prevention program. The study has two objectives; firstly to find the effective strategies in improving waria’s feminine skills such as knitting, hair dressing. Secondly to find the effective programs both on-stage and off-stage to improve the quality of ludruk performance such as revitalizing their marketing management, using social media to promote their schedule to the young generation. Some inportant points can be conluded from this study. Firstly, integrated coordinating system between ludruk artist waria and waria communities such as Perwakos and Iwama should be improved. HIV/AIDS prevention programs become uneffective without coordination. In this point, ludruk artist waria need to know that HIV/AIDS prevention programs such as VCT, HIV testing is free of charge. Secondly, in terms of management internal system, ludruk needs to revitalize the content of the story in their performance to be more compatible with the younger audience. To do so, the cooperation is needed among all the stakeholeders to make ludruk survive in the capitalist industrial show business in Indonesia.Salah satu populasi kunci yang memberi kontribusi tingginya prevalensi HIV dan AIDS di JATIM adalah komunitas waria karena di propinsi ini estimasi jumlah waria terbesar di Indonesia.

Impact of HIV prevention programs on drug users in Malaysia.

Science.gov (United States)

Kamarulzaman, Adeeba

2009-11-01

Faced with a rising HIV epidemic among injecting drug users, harm reduction policies and programs were introduced in Malaysia in 2005. The positive impact seen since the introduction of these programs comprise the inclusion of the health aspects of illicit drug use in the country's drug policies; better access to antiretroviral therapy for injecting drug users who are HIV infected; reduction in HIV-risk behavior; and greater social benefits, including increased employment. Despite these achievements, tension between law enforcement and public health persists, as harm reduction exists alongside an overall drug policy that is based on abstinence and zero tolerance. Unless there is harmonization of this policy, sustainability and scale-up of harm reduction programs will remain a challenge.

Blood transfusion service centers in Nigeria screen donated blood for markers of HIV infection using antibody- (Ab) based rapid test and in some centers, positives are re-tested using Ab-based ELISA. Paucity of data exists on p24 antigen prevalence among HIV Ab-negative donors in Nigeria. This study aims at detecting HIV p24 antigen among prospective blood donors in Osun State, Nigeria. Prospective blood donors negative for HIV antibodies using Determine test kit were re-tested using BIORAD GENSCREEN Ultra Ag-Ab ELISA kit, a fourth-generation ELISA kit that detects HIV antibodies/p24 antigen. Of the 169 HIV Ab-negative prospective donors, 10 (5.9%) were positive for HIV p24 antigen and 70% (7/10) of them were in the age range 18-30 years. Results of this study show that blood transfusion is still one of the major routes of HIV transmission in Nigeria and a higher proportion is among youth. Inclusion of p24 antigen testing into the blood donor screening will help reduce transfusion associated HIV in Nigeria if Nucleic Acid Testing (NAT) of all blood donor samples is not affordable; also, HIV enlightenment programs tailored toward youth may help reduce this rate among donors since more young people donate blood in low/middle-income countries than in high-income countries.

Risk factors for neurocognitive impairment in HIV-infected patients and comparison of different screening tools

Elisa Moreira de Souza

Full Text Available HIV-associated neurocognitive disorder (HAND is relatively frequent among HIV-infected patients and is often underdiagnosed. Assessment of HAND in daily clinical practice is challenging and different tools have been proposed. Objective : To evaluate risk factors and compare different screening tools for neurocognitive impairment in HIV-infected patients. Methods : HIV-infected patients were evaluated using the International HIV-Dementia Scale (IHDS, Mini-Mental State Examination (MMSE and a neurocognitive self-perception questionnaire recommended by the European AIDS Clinical Society. Sociodemographic, clinical and laboratory data were obtained through chart review and patient interview. Results : Among the 63 patients included, low performance on the IHDS was observed in 54.0% and IHDS score was inversely associated with age (OR 0.13; 95%CI [0.02-0.67]. Regarding cognitive self-perception, 63.5% of patients reported no impairment on the three domains covered by the questionnaire. Among those patients self-reporting no problems, 42.1% had low performance on the IHDS. None of the patients scored below the education-adjusted cut-off on the MMSE. Conclusion : IHDS scores suggestive of HAND were observed in more than half of the patients and lower scores were found among older patients. There was low agreement between the different tools, suggesting that the MMSE may be inadequate for assessing HAND. The self-assessment questionnaire had low sensitivity and might not be useful as a screening tool.

The aim of this study was to review, systematically and critically, evidence used to derive estimates of cost-effectiveness of human immunodeficiency virus (HIV) screening. A systematic review was conducted. Searched were three main electronic bibliographic databases from 1993 to 2008 using key words including HIV, mass screening, HAART, economic evaluation, cost-effectiveness analysis, modeling. We included studies of sexually transmitted HIV infection in both sexes, including studies comparing diagnostic testing protocols and partner notification. Outcomes included were cases of HIV infection detected, deterioration to the AIDS state, secondary transmission of HIV, the quality-adjusted life-years/survival, costs, and cost-effectiveness of HIV screening. Eighty-four papers were identified; ten of which were formal economic evaluations, one cost study, three effectiveness studies, and three systematic reviews of HIV prevention programs. The predominant assertion was that HIV screening is cost-effective; methodological problems, such as the preponderance of static models which are inappropriate for infectious diseases, varying perspectives from which the studies were analyzed, and arbitrary threshold incremental cost-effectiveness ratio levels, limited the validity of these findings, and their usefulness in informing health policy decisions. The majority of published economic evaluations are based on inappropriate static models. This flaw renders the results of these studies as inconclusive and the purported cost-effectiveness of HIV screening debatable. The results of this review could form a basis for consideration of further research and analysis by health economists into the cost-effectiveness of HIV screening.

Fragment-based drug discovery has been applied with varying levels of success to a number of proteins involved in the HIV (Human Immunodeficiency Virus) life cycle. Fragment-based approaches have led to the discovery of novel binding sites within protease, reverse transcriptase, integrase, and gp41. Novel compounds that bind to known pockets within CCR5 have also been identified via fragment screening, and a fragment-based approach to target the TAR-Tat interaction was explored. In the context of HIV-1 reverse transcriptase (RT), fragment-based approaches have yielded fragment hits with mid-μM activity in an in vitro activity assay, as well as fragment hits that are active against drug-resistant variants of RT. Fragment-based drug discovery is a powerful method to elucidate novel binding sites within proteins, and the method has had significant success in the context of HIV proteins.

The aim of the study was to test whether a screening navigation program leads to more favorable health beliefs and decreases social inequalities in them. The selected 261 noncompliant participants in a screening navigation versus a usual screening program arm had to respond to health belief measures inspired by the Protection Motivation Theory. Regression analyses showed that social inequalities in perceived efficacy of screening, favorable attitude, and perceived facility were reduced in the screening navigation compared to the usual screening program. These results highlight the importance of health beliefs to understand the mechanism of screening navigation programs in reducing social inequalities. © The Author(s) 2014.

Early diagnosis of human immunodeficiency virus (HIV) infection and initiation of antiretroviral treatment (ART) improves health outcomes and prevents HIV transmission. Before 2010, HIV testing was available to inmates in the California state prison system upon request. In 2010, the California Correctional Health Care Services (CCHCS) integrated HIV opt-out screening into the health assessment for inmates entering California state prisons. Under this system, a medical care provider informs the inmate that an HIV test is routinely done, along with screening for sexually transmitted, communicable, and vaccine-preventable diseases, unless the inmate specifically declines the test. During 2012-2013, CCHCS, the California Department of Public Health, and CDC evaluated HIV screening, rates of new diagnoses, linkage to and retention in care, ART response, and post-release linkage to care among California prison inmates. All prison inmates are processed through one of eight specialized reception center facilities, where they undergo a comprehensive evaluation of their medical needs, mental health, and custody requirements for placement in one of 35 state prisons. Among 17,436 inmates who entered a reception center during April-September 2012, 77% were screened for HIV infection; 135 (1%) tested positive, including 10 (0.1%) with newly diagnosed infections. Among the 135 HIV-positive patient-inmates, 134 (99%) were linked to care within 90 days of diagnosis, including 122 (91%) who initiated ART. Among 83 who initiated ART and remained incarcerated through July 2013, 81 (98%) continued ART; 71 (88%) achieved viral suppression (care within 30 days of release were virally suppressed at that time. Only one of nine persons with a viral load test conducted between 91 days and 1 year post-release had viral suppression. Although high rates of viral suppression were achieved in prison, continuity of care in the community remains a challenge. An infrastructure for post

Full Text Available Background and aims: Men who have sex with men (MSM infected with human immunodeficiency virus (HIV have the highest risk of developing anal cancer (AC. The objective of this study was to describe our screening implementation program in this population, and report the prevalence of human papillomavirus (HPV anal infection, and cytological and histological findings in a Spanish medium-size community (Vigo, Spain. Method: Prospective cohort analysis of 240 HIV-infected MSM. Cellular anal sample and high risk HPV (HR-HPV-tests were performed to study cytological changes and HPV genotyping. High resolution anoscopy (HRA was performed in 209 patients. Results were analyzed with respect to epidemiological, clinical and analytical factors. Results: Of 209 patients selected for HRA, the prevalence of HR-HPV anal infection, cytological and histological alterations was 85.6%, 47.5%, and 39.8%, respectively. Sensitivity and specificity for ≥ ASCUS (atypia of squamous cells of undetermined significance cytology in relation to histological alterations were 61% and 85%, (OR: 8.7; IC 95%: 4.4-17.2, respectively. Observed concordance between high-grade squamous intraepithelial lesion (HSIL cytology and HSIL anal intraepithelial neoplasia types 2 and 3 (AIN-2/3 histology was 64% (OR: 11.4; IC 95%: 3.6-36.7. One patient with HSIL cytology presented a prevalent anal squamous carcinoma. Conclusions: HRA was feasible with similar results to relevant groups. There was a high prevalence of anal HR-HPV infection, and cytological and histological alterations.

We evaluated the feasibility of “screen and treat approach” for cervical cancer prevention and the performance of different screening tests among FSWs.Methods: Women were screened using cytology, VIA (visual inspection with acetic acid, and VILI (visual inspection with Lugol’s iodine and underwent colposcopy, biopsy, and immediate treatment using cold coagulation, if indicated, at the same visit.Results: We screened 300 FSWs of whom 200 (66.67% were HIV uninfected and 100 (33.34% were HIV infected. The overall prevalence of CIN 2–3 lesions was 4.7%. But all women with CIN 2–3 lesions were HIV infected, and thus the prevalence of CIN 2–3 lesions in HIV-infected FSWs was 14/100 (14%, 95% confidence interval: 7.2–20.8. All of them screened positive by all three screening tests. Cold coagulation was well tolerated, with no appreciable side effects.Conclusion: Cervical cancer prevention by “screen and treat” approach using VIA, followed by ablative treatment, in this high-risk group of women is feasible and can be implemented through various targeted intervention programs.

A case note audit was undertaken of HIV-positive men who have sex with men (MSM) to ascertain whether national guidelines for taking sexual histories, including recreational drug use and sexually transmitted infection (STI) screening were being met. The notes of 142 HIV-positive men seen in 2015 were available, of whom 85 were MSM. Information was collected regarding sexual history, recreational drug use documentation, sexually transmitted infection screen offer and test results. Seventy-seven (91%) of the MSM had a sexual history documented, of whom 60 (78%) were sexually active. STI screens were offered to 58/60 (97%) of those who were sexually active and accepted by 53 (91%). Twelve (23%) of these had an STI. A recreational drug history was taken in 63 (74%) with 17 (27%) reporting use and 3 (5%) chemsex. The high rate of STIs highlights that regular screening in this group is essential. Additionally, the fact that over a quarter reported recreational drug use and given the increasing concern around chemsex, questions about this should be incorporated into the sexual history proforma.

To address the implementation of the National Newborn Screening Program (NBS) in Saudi Arabia and stratify the incidence of the screened disorders. A retrospective study conducted between 1 August 2005 and 31 December 2012, total of 775 000 newborns were screened from 139 hospitals distributed among all regions of Saudi Arabia. The NBS Program screens for 16 disorders from a selective list of inborn errors of metabolism (IEM) and endocrine disorders. Heel prick dry blood spot samples were obtained from all newborns for biochemical and immunoassay testing. Recall screening testing was performed for Initial positive results and confirmed by specific biochemical assays. A total of 743 cases were identified giving an overall incidence of 1:1043. Frequently detected disorders nationwide were congenital hypothyroidism and congenital adrenal hyperplasia with an incidence of 1:7175 and 1:7908 correspondingly. The highest incidence among the IEM was propionic acidaemia with an incidence rate of 1:14 000. The article highlights the experience of the NBS Program in Saudi Arabia and providing data on specific regional incidences of all the screened disorders included in the programme; and showed that the incidence of these disorders is one of the highest reported so far world-wide. © 2017 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).

Routine HIV testing among hospitalized patients in Argentina. is it time for a policy change?

Directory of Open Access Journals (Sweden)

María Eugenia Socías

Full Text Available INTRODUCTION: The Argentinean AIDS Program estimates that 110,000 persons are living with HIV/AIDS in Argentina. Of those, approximately 40% are unaware of their status, and 30% are diagnosed in advanced stages of immunosuppression. Though studies show that universal HIV screening is cost-effective in settings with HIV prevalence greater than 0.1%, in Argentina, with the exception of antenatal care, HIV testing is always client-initiated. OBJECTIVE: We performed a pilot study to assess the acceptability of a universal HIV screening program among inpatients of an urban public hospital in Buenos Aires. METHODS: Over a six-month period, all eligible adult patients admitted to the internal medicine ward were offered HIV testing. Demographics, uptake rates, reasons for refusal and new HIV diagnoses were analyzed. RESULTS: Of the 350 admissions during this period, 249 were eligible and subsequently enrolled. The enrolled population was relatively old compared to the general population, was balanced on gender, and did not report traditional high risk factors for HIV infection. Only 88 (39% reported prior HIV testing. One hundred and ninety (76% patients accepted HIV testing. In multivariable analysis only younger age (OR 1.02; 95%CI 1.003-1.05 was independently associated with test uptake. Three new HIV diagnoses were made (undiagnosed HIV prevalence: 1.58%; none belonged to a most-at-risk population. CONCLUSIONS: Our findings suggest that universal HIV screening in this setting is acceptable and potentially effective in identifying undiagnosed HIV-infected individuals. If confirmed in a larger study, our findings may inform changes in the Argentinean HIV testing policy.

The efficacy of a computer-based interactive multimedia HIV/AIDS prevention program for men with intellectual disability (ID) was examined using a quasi-experimental within-subjects design. Thirty-seven men with mild to moderate intellectual disability evaluated the program. The pretest and posttest instruments assessed HIV/AIDS knowledge (high-risk fluids, HIV transmission, and condom facts) and condom application skills. All outcome measures showed statistically significant gains from pretest to posttest, with medium to large effect sizes. In addition, a second study was conducted with twelve service providers who work with men with ID. Service providers reviewed the HIV/AIDS prevention program, completed a demographics questionnaire, and a program satisfaction survey. Overall, service providers rated the program highly on several outcome measures (stimulation, relevance, and usability).

Brain transcriptome-wide screen for HIV-1 Nef protein interaction partners reveals various membrane-associated proteins.

Directory of Open Access Journals (Sweden)

Ellen C Kammula

Full Text Available HIV-1 Nef protein contributes essentially to the pathology of AIDS by a variety of protein-protein-interactions within the host cell. The versatile functionality of Nef is partially attributed to different conformational states and posttranslational modifications, such as myristoylation. Up to now, many interaction partners of Nef have been identified using classical yeast two-hybrid screens. Such screens rely on transcriptional activation of reporter genes in the nucleus to detect interactions. Thus, the identification of Nef interaction partners that are integral membrane proteins, membrane-associated proteins or other proteins that do not translocate into the nucleus is hampered. In the present study, a split-ubiquitin based yeast two-hybrid screen was used to identify novel membrane-localized interaction partners of Nef. More than 80% of the hereby identified interaction partners of Nef are transmembrane proteins. The identified hits are GPM6B, GPM6A, BAP31, TSPAN7, CYB5B, CD320/TCblR, VSIG4, PMEPA1, OCIAD1, ITGB1, CHN1, PH4, CLDN10, HSPA9, APR-3, PEBP1 and B3GNT, which are involved in diverse cellular processes like signaling, apoptosis, neurogenesis, cell adhesion and protein trafficking or quality control. For a subfraction of the hereby identified proteins we present data supporting their direct interaction with HIV-1 Nef. We discuss the results with respect to many phenotypes observed in HIV infected cells and patients. The identified Nef interaction partners may help to further elucidate the molecular basis of HIV-related diseases.

With the decline in funding for Viet Nam's response to the HIV epidemic, there is a need for evidence on the criteria to guide the prioritization of HIV programs. There is a gap in the research on the relative importance of multiple criteria for prioritizing a package of interventions. This study elicits preferences and the trade-offs made between different HIV programs by relevant stakeholders and decision-makers in Viet Nam. It also pays attention to how differences in social and professional characteristics of stakeholders and their agency affiliations shape preferences for HIV program criteria in Viet Nam. This study uses self-explicated ranking and discrete choice experiments to determine the relative importance of five criteria - effectiveness, feasibility, cost-effectiveness, rate of investment and prevention/treatment investment ratio - to stakeholders when they evaluate and select hypothetical HIV programs. The study includes 69 participants from government, civil society, and international development partners. Results of the discrete choice experiment show that overall the feasibility criterion is ranked highest in importance to the participants when choosing a hypothetical HIV program, followed by sustainability, treatment to prevention spending ratio, and effectiveness. The participant's work in management, programming, or decision-making has a significant effect on the importance of some criteria to the participant. In the self-explicated ranking effectiveness is the most important criterion and the cost-effectiveness criterion ranks low in importance across all groups. This study has shown that the preferred HIV program in Viet Nam is feasible, front-loaded for sustainability, has a higher proportion of investment on prevention, saves more lives and prevents more infections. Similarities in government and civil society rankings of criteria can create common grounds for future policy dialogues between stakeholders. Innovative models of planning should

The purpose of this quantitative study is to understand the global security perspective on the effects of executive cognitive function (ECF) on Complex Behavioral Screening Intervention and HIV/AIDS. The HIV/AIDS pandemic is as much a social, political, economic, and cultural problem as a biomedical one. HIV/AIDS is associated centrally with the collapse not just of communities and families but potentially of states, with some of the largest public health interventions ever and enormous questions about governance, a huge population of orphans, and deep questions about intergenerational relations and cultural transmission. This study also is to develop a screening instrument that improves quality of life for individuals with executive cognitive impairments and behavior problems in our communities and the global society.

Cervical cancer screening is one of the most effective cancer prevention strategies, but most women in Africa have never been screened. In 2007, the Cameroon Baptist Convention Health Services, a large faith-based health care system in Cameroon, initiated the Women's Health Program (WHP) to address this disparity. The WHP provides fee-for-service cervical cancer screening using visual inspection with acetic acid enhanced by digital cervicography (VIA-DC), prioritizing care for women living with HIV/AIDS. They also provide clinical breast examination, family planning (FP) services, and treatment for reproductive tract infection (RTI). Here, we document the strengths and challenges of the WHP screening program and the unique aspects of the WHP model, including a fee-for-service payment system and the provision of other women's health services. We retrospectively reviewed WHP medical records from women who presented for cervical cancer screening from 2007-2014. In 8 years, WHP nurses screened 44,979 women for cervical cancer. The number of women screened increased nearly every year. The WHP is sustained primarily on fees-for-service, with external funding totaling about $20,000 annually. In 2014, of 12,191 women screened for cervical cancer, 99% received clinical breast exams, 19% received FP services, and 4.7% received treatment for RTIs. We document successes, challenges, solutions implemented, and recommendations for optimizing this screening model. The WHP's experience using a fee-for-service model for cervical cancer screening demonstrates that in Cameroon VIA-DC is acceptable, feasible, and scalable and can be nearly self-sustaining. Integrating other women's health services enabled women to address additional health care needs. The Cameroon Baptist Convention Health Services Women's Health Program successfully implemented a nurse-led, fee-for-service cervical cancer screening program using visual inspection with acetic acid-enhanced by digital cervicography in

Although U.S. prison inmates have higher rates of HIV infection than the general population, most inmates are not routinely tested for HIV infection at prison entry. The study objective was to implement a routine, voluntary HIV testing program in a Massachusetts county prison. During admission, inmates were given group HIV pre-test counseling and were subsequently offered private HIV testing. This intervention was compared to a control period during which HIV testing was provided only upon inmate or physician request. Between November 2004 and April 2005, 1,004 inmates met inclusion criteria and were offered routine, voluntary HIV testing. Of these, 734 (73.1%) accepted, 2 (0.3%) were HIV-infected, and 457 (45.5%) had been tested for HIV in the previous year. The testing rate of 73.1% was significantly increased from the rate of 18.0% (318 of 1,723) during the control period (pprison setting. Careful attention should be paid to prevent redundancy of testing efforts in the prison population. Implementing a routine HIV testing program among prison inmates greatly increased testing rates compared to on-request testing.

Full Text Available Background & aim: Sexually transmitted infections (STIs present a serious public health burden, which are considered as the factors contributing to acute illnesses, infertility, long-term disability, and mortality. The aim of the present study was to provide an in-depth understanding of the participants' perceptions about the integration of gender-sensitive approach to safe motherhood program for the prevention of STIs/human immunodeficiency virus (HIV in Iran. Methods: This qualitative exploratory study was conducted on 32 male and female key informants, including health managers, health policy makers, and reproductive health providers. The participants were selected through the purposive sampling method, followed by the snowball sampling technique. The data collection was performed using the semi-structured interviews. The data were analyzed through the content analysis. Results: Based on the results, the participants’ perceptions were categorized into two categories, namely the STIs/HIV prevention among males in safe motherhood and gender-sensitivity in primary maternal STIs/HIV prevention. Each of the patients was further divided into codes. The first category includes accountability to men's own sexual health needs’ and prevention of ill-health effects of men on women’s STIs/HIV status and the second category includes (1 condom negotiation skills in women (2 mandatory pre-marital HIV test policy, (3 partner notification guidelines, (4 STI/HIV risk assessment in safe motherhood services, and (5 women’s right-based instruction for prenatal HIV screening in private services. Conclusion: As the findings of the present study indicated, the health policy makers were not adequately sensitive to gender sensitivity, which is particularly crucial for STIs/HIV prevention in the safe motherhood programs.

Tuberculosis (TB) and human immunodeficiency virus (HIV) represent two of the greatest health threats in African prisons. In 2010, collaboration between the Centre for Infectious Disease Research in Zambia, the Zambia Prisons Service, and the National TB Program established a TB and HIV screening program in six Zambian prisons. We report data on the prevalence of TB and HIV in one of the largest facilities: Lusaka Central Prison. Between November 2010 and April 2011, we assessed the prevalence of TB and HIV amongst inmates entering, residing, and exiting the prison, as well as in the surrounding community. The screening protocol included complete history and physical exam, digital radiography, opt-out HIV counseling and testing, sputum smear and culture. A TB case was defined as either bacteriologically confirmed or clinically diagnosed. A total of 2323 participants completed screening. A majority (88%) were male, median age 31 years and body mass index 21.9. TB symptoms were found in 1430 (62%). TB was diagnosed in 176 (7.6%) individuals and 52 people were already on TB treatment at time of screening. TB was bacteriologically confirmed in 88 cases (3.8%) and clinically diagnosed in 88 cases (3.8%). Confirmed TB at entry and exit interventions were 4.6% and 5.3% respectively. Smear was positive in only 25% (n = 22) of bacteriologically confirmed cases. HIV prevalence among inmates currently residing in prison was 27.4%. Ineffective TB and HIV screening programs deter successful disease control strategies in prison facilities and their surrounding communities. We found rates of TB and HIV in Lusaka Central Prison that are substantially higher than the Zambian average, with a trend towards concentration and potential transmission of both diseases within the facility and to the general population. Investment in institutional and criminal justice reform as well as prison-specific health systems is urgently required.

Industrial screening programs for workers

International Nuclear Information System (INIS)

Lavine, M.P.

1982-01-01

Industrial screening efforts to identify classes of workers who are more susceptible to workplace hazards, by virtue of their fertility, genetic, or lifestyle characteristics, represent a relatively new approach to reducing workplace risks. Screening has already raised some important economic, legal, social, medical, and moral questions. Employers, employees, administrative agencies, and the courts are offering different, often conflicting answers. Ultimately the acceptability of various screening schemes rests upon judgments about how a society justifies the distribution of risk. The questions that industrial screening programs raise are only partially answered by empirical evidence; the rest is a matter of values

To determine whether our health care employees were undergoing mammography screening according to American Cancer Society guidelines and to determine whether aggressive outreach, education and streamlining of mammography scheduling could improve compliance. All female employees at North Shore University Hospital (NSUH) and several other health system facilities (SF) were sent mailings to their homes that included breast health education and mammography screening guidelines, a questionnaire regarding their own mammography screening history and the opportunity to have their mammography screening scheduled by the Mammography Screening Employee Inreach Program (MSEIP) coordinator. Of the approximately 2,700 female employees aged 40 and over at NSUH and SF, 2,235 (82.7%) responded to the questionnaire, and 1,455 had a mammogram done via the MSEIP. Of the 1,455, 43% either were overdue for a mammogram or had never had one. During a second year of the MSEIP at NSUH and SF, an additional 1,706 mammograms were done. People employed in health care jobs do not necessarily avail themselves of appropriate health care screening. An aggressive program that utilized education, outreach and assistance with scheduling was effective in increasing compliance with mammography screening.

Highlights: • We found variation in early performance measures across screening centres. • Radiologists’ performance may play a key role in the variability. • Potential to improve the effectiveness of breast cancer screening programs. • Continuous surveillance of screening centres and radiologists is essential. - Abstract: Background: Recall for assessment in mammographic screening entails an inevitable number of false-positive screening results. This study aimed to investigate the variation in the cumulative risk of a false positive screening result and the positive predictive value across the screening centres in the Norwegian Breast Cancer Screening Program. Methods: We studied 618,636 women aged 50–69 years who underwent 2,090,575 screening exams (1996–2010. Recall rate, positive predictive value, rate of screen-detected cancer, and the cumulative risk of a false positive screening result, without and with invasive procedures across the screening centres were calculated. Generalized linear models were used to estimate the probability of a false positive screening result and to compute the cumulative false-positive risk for up to ten biennial screening examinations. Results: The cumulative risk of a false-positive screening exam varied from 10.7% (95% CI: 9.4–12.0%) to 41.5% (95% CI: 34.1–48.9%) across screening centres, with a highest to lowest ratio of 3.9 (95% CI: 3.7–4.0). The highest to lowest ratio for the cumulative risk of undergoing an invasive procedure with a benign outcome was 4.3 (95% CI: 4.0–4.6). The positive predictive value of recall varied between 12.0% (95% CI: 11.0–12.9%) and 19.9% (95% CI: 18.3–21.5%), with a highest to lowest ratio of 1.7 (95% CI: 1.5–1.9). Conclusions: A substantial variation in the performance measures across the screening centres in the Norwegian Breast Cancer Screening Program was identified, despite of similar administration, procedures, and quality assurance requirements.

Neurodevelopmental delay or HIV encephalopathy is a stage four disease indicator for paediatric HIV/AIDS according to the World Health Organisation (WHO), and may be used as a criterion for initiation of highly active antiretroviral therapy (HAART). To date, the only means of prevention of this condition is early initiation of HAART. Studies which have been carried out in South African clinics have revealed the high prevalence of this condition. In developing countries, commencement of HAART is based on declining virologic and immunologic status, as standardised neurodevelopmental assessment tools are not widely available. A standardised developmental screening tool which is suitable for use in a developing country is therefore necessary in order to screen for neurodevelopmental delay to allow for further assessment and referral to rehabilitation services, as well as providing an additional assessment criterion for initiation of HAART. The infant gross motor screening test (IGMST) was developed for this purpose. The standardisation sample of the IGMST consisted of 112 HIV-infected infants between six and 18 months of age. Item selection for the IGMST was based on the Gross Motor scale of the Bayley Scales of Infant Development (BSID)-III. Content validity was assessed by a panel of experts using a nominal group technique (NGT; agreement >80%). Concurrent validity (n=60) of the IGMST was carried out against the BSID-III, and agreement was excellent (K=0.85). The diagnostic properties of the IGMST were evaluated and revealed: sensitivity 97.4%, specificity 85.7%, positive predictive value (PPV) 92.7%, and negative predictive value (NPV) 94.7%. Reliability testing (n=30) revealed inter-rater reliability as: r=1, test-retest reliability: r=0.98 and intra-rater reliability: r=0.98. The results indicate that the statistical properties of the IGMST are excellent, and the tool is suitable for use within the paediatric HIV setting.

Primary Breast lymphoma is a rare lesion that has been reported in patients without HIV. However, Primary Breast lymphoma occurring in a patient with HIV has rarely been reported despite the fact that HIV infection is known to increase the propensity to develop certain types of lymphoma. We report a case of an HIV patient with breast lymphoma that was discovered by screening mammography while presenting our argument for more cautionary management in this patient population.

Full Text Available Abstract Background There is great diversity in the policies for scoliosis screening worldwide. The initial enthusiasm was succeeded by skepticism and the worth of screening programs has been challenged. The criticisms of school screening programs cite mainly the negative psychological impact on children and their families and the increased financial cost of visits and follow-up radiographs. The purpose of this report is to evaluate the direct cost of performing the school screening in a district hospital. Methods A cost analysis was performed for the estimation of the direct cost of the "Thriasio" school-screening program between January 2000 and May 2006. The analysis involved all the 6470 pupils aged 6–18 years old who were screened at schools for spinal deformities during this period. The factors which were taken into consideration in order to calculate the direct cost of the screening program were a the number of the examiners b the working hours, c the examiners' salary, d the cost of transportation and finally e the cost of examination per child. Results During the examined period 20 examiners were involved in the program and worked for 1949 working hours. The hourly salary for the trainee doctors was 6.80 euro, for the Health Visitors 6.70 euro and for the Physiotherapists 5.50 euro in current prices. The cost of transportation was 32 euro per year. The direct cost for the examination of each child for the above studied period was calculated to be 2.04 euro. Conclusion The cost of our school-screening program is low. The present study provides a strong evidence for the continuation of the program when looking from a financial point of view.

Patients diagnosed with lymphogranuloma venereum have high rates of co-infection with HIV, syphilis and hepatitis C. The aim of this enhanced surveillance was to screen all men who have sex with men (MSM) newly diagnosed with HIV, syphilis or hepatitis C for co-infection with asymptomatic lymphogranuloma venereum as part of the recommended sexual health screen. Of the 145 patients screened, 21 patients were diagnosed with rectal Chlamydia trachomatis, one with both rectal and urethral chlamydia and six with urethral chlamydia. One rectal chlamydia-positive sample, when tested, was equivocal for lymphogranuloma venereum. Our data suggested that there was not a pool of asymptomatic lymphogranuloma venereum infection in MSM recently diagnosed with HIV, hepatitis C and syphilis. However, there have been recent reports of an increased incidence of asymptomatic lymphogranuloma venereum, raising the question whether lymphogranuloma venereum should be screened for in high risk asymptomatic MSM. The prevalence of asymptomatic rectal chlamydia infections was 19%. © The Author(s) 2015.

Spillover effects of HIV testing policies: changes in HIV testing guidelines and HCV testing practices in drug treatment programs in the United States

Full Text Available Abstract Background To examine the extent to which state adoption of the Centers for Disease Control and Prevention (CDC 2006 revisions to adult and adolescent HIV testing guidelines is associated with availability of other important prevention and medical services. We hypothesized that in states where the pretest counseling requirement for HIV testing was dropped from state legislation, substance use disorder treatment programs would have higher availability of HCV testing services than in states that had maintained this requirement. Methods We analyzed a nationally representative sample of 383 opioid treatment programs from the 2005 and 2011 National Drug Abuse Treatment System Survey (NDATSS. Data were collected from program directors and clinical supervisors through telephone surveys. Multivariate logistic regression models were used to measure associations between state adoption of CDC recommended guidelines for HIV pretest counseling and availability of HCV testing services. Results The effects of HIV testing legislative changes on HCV testing practices varied by type of opioid treatment program. In states that had removed the requirement for HIV pretest counseling, buprenorphine-only programs were more likely to offer HCV testing to their patients. The positive spillover effect of HIV pretest counseling policies, however, did not extend to methadone programs and did not translate into increased availability of on-site HCV testing in either program type. Conclusions Our findings highlight potential positive spillover effects of HIV testing policies on HCV testing practices. They also suggest that maximizing the benefits of HIV policies may require other initiatives, including resources and programmatic efforts that support systematic integration with other services and effective implementation.

HIV/AIDS, food supplementation and livelihood programs in Uganda: a way forward?

Directory of Open Access Journals (Sweden)

Jessica E Yager

Full Text Available BACKGROUND: Over the last decade, health, nutrition and policy experts have become increasingly aware of the many ways in which food insecurity and HIV infection negatively impact and reinforce one another. In response, many organizations providing HIV care began supplying food aid to clients in need. Food supplementation, however, was quickly recognized as an unsustainable and incomplete intervention. Many HIV care organizations therefore developed integrated HIV and livelihood programs (IHLPs to target the root causes of food insecurity. METHODS AND FINDINGS: We conducted a qualitative study using in-depth interviews with 21 key informants who worked at seven organizations providing HIV care, food aid, or IHLPs in Kampala, Uganda in 2007-2008 to better understand the impact of IHLPs on the well-being of people living with HIV and AIDS (PLWHAs and the challenges in transitioning clients from food aid to IHLPs. There was strong consensus among those interviewed that IHLPs are an important intervention in addressing food insecurity and its adverse health consequences among PLWHAs. Key informants identified three main challenges in transitioning PLWHAs from food supplementation programs to IHLPs: (1 lack of resources (2 timing of the transition and (3 logistical considerations including geography and weather. Factors seen as contributing to the success of programs included: (1 close involvement of community leaders (2 close ties with local and national government (3 diversification of IHLP activities and (4 close integration with food supplementation programs, all linked through a central program of HIV care. CONCLUSION: Health, policy and development experts should continue to strengthen IHLPs for participants in need. Further research is needed to determine when and how participants should be transitioned from food supplementation to IHLPs, and to determine how to better correlate measures of food insecurity with objective clinical outcomes so

Full Text Available Abstract Background The purpose of this study is to propose the Least Absolute Shrinkage and Selection Operators procedure (LASSO as an alternative to conventional variable selection models, as it allows for easy interpretation and handles multicollinearities. We developed a model on the basis of LASSO-selected parameters in order to link associated demographical, socio-economical, clinical and immunological factors to performing tuberculosis screening in HIV-positive patients in Ghana. Methods Applying the LASSO method and multivariate logistic regression analysis on a large public health data set, we selected relevant predictors related to tuberculosis screening. Results One Thousand Ninety Five patients infected with HIV were enrolled into this study with 691 (63.2 % of them having tuberculosis screening documented in their patient folders. Predictors found to be significantly associated with performance of tuberculosis screening can be classified into factors related to the clinician’s perception of the clinical state, as well as those related to PLHIV’s awareness. These factors include newly diagnosed HIV infections (n = 354 (32.42 %, aOR 1.84, current CD4+ T cell count (aOR 0.92, non-availability of HIV type (n = 787 (72.07 %, aOR 0.56, chronic cough (n = 32 (2.93 %, aOR 5.07, intake of co-trimoxazole (n = 271 (24.82 %, aOR 2.31, vitamin supplementation (n = 220 (20.15 %, aOR 2.64 as well as the use of mosquito bed nets (n = 613 (56.14 %, aOR 1.53. Conclusions Accelerated TB screening among newly diagnosed HIV-patients indicates that application of the WHO screening form for intensifying tuberculosis case finding among HIV-positive individuals in resource-limited settings is increasingly adopted. However, screening for TB in PLHIV is still impacted by clinician’s perception of patient’s health state and PLHIV’s health awareness. Education of staff, counselling of PLHIV and sufficient financing are

There is limited information on the impact of the HIV/AIDS epidemic on Latino migrant workers (LMWs), although available data indicate that this community is being disproportionally affected. The need for prevention programs that address the specific needs of LMWs is becoming well recognized. HIV prevention interventions that train and employ community health workers are a culturally appropriate way to address the issues of community trust and capacity building in this community. This article describes the Latino Migrant Worker HIV Prevention Program and its efforts to train and engage community health workers in the prevention of HIV among LMWs in South Florida.

An inmate cannot sue the Taylorville Correctional Center in Illinois under the Americans with Disabilities Act (ADA) for requiring an HIV test for enrollment in a prison program. [Name removed] wanted to participate in the prison's culinary arts program, but did not want to take the HIV test. The 7th U.S. Circuit Court of Appeals ruled that [name removed] was not a "qualified individual with a disability" and therefore could not sue under ADA. The policy justification for the HIV test, which is required of all inmates enrolling in the program, was not addressed by the court.

To provide evidence for resource allocation and cooperation between domestic and international HIV/AIDS programs in China by analyzing the needs and current levels of resource input in provinces. National and provincial international cooperation program investment and allocation data from 2000 to 2006 were collected. Several factors in each province were analyzed through multiple regression analysis in order to determine whether they had a statistical correlation to the distribution of international HIV/AIDS program resources in China, including: the Gross Domestic Product (GDP), the number of accumulated people living with HIV/AIDS, and the number of accumulated people living with AIDS. Then the Z values were calculated at each provincial level and compared with related international investment. The resource allocation in different program areas were compared with the level of resource input by international and central government HIV/AIDS prevention and control programs through Chi-square test. The international cooperation program investment at local level from 2000 to 2006 were 4893, 24 669, 50 567, 52 950, 112 143, 363 396 and 247 045 thousand RMB respectively, and at national level were 3007, 19 726, 29 035, 37 530, 77 500, 105 786 and 77 035 thousand RMB respectively. There was a statistical correlation between international HIV/AIDS program resource input and the accumulated number of people living with AIDS (R is 0.56 and 0.69 accordingly, and P international resource input and the GDP of each province. International HIV/AIDS cooperation programs did not invest in each province according to its practical needs (R = 0.066, P = 0.725). The international cooperation program investments and needs in different province could not meet completely. The ranks of Z value in Guangdong, Shandong and Jiangsu were 3, 5 and 6, but the ranks of international cooperation program in those provinces were 18, 13 and 28 respectively. The investment proportion for national

Full Text Available Abstract Background With the decline in funding for Viet Nam’s response to the HIV epidemic, there is a need for evidence on the criteria to guide the prioritization of HIV programs. There is a gap in the research on the relative importance of multiple criteria for prioritizing a package of interventions. This study elicits preferences and the trade-offs made between different HIV programs by relevant stakeholders and decision-makers in Viet Nam. It also pays attention to how differences in social and professional characteristics of stakeholders and their agency affiliations shape preferences for HIV program criteria in Viet Nam. Methods This study uses self-explicated ranking and discrete choice experiments to determine the relative importance of five criteria - effectiveness, feasibility, cost-effectiveness, rate of investment and prevention/treatment investment ratio - to stakeholders when they evaluate and select hypothetical HIV programs. The study includes 69 participants from government, civil society, and international development partners. Results Results of the discrete choice experiment show that overall the feasibility criterion is ranked highest in importance to the participants when choosing a hypothetical HIV program, followed by sustainability, treatment to prevention spending ratio, and effectiveness. The participant’s work in management, programming, or decision-making has a significant effect on the importance of some criteria to the participant. In the self-explicated ranking effectiveness is the most important criterion and the cost-effectiveness criterion ranks low in importance across all groups. Conclusions This study has shown that the preferred HIV program in Viet Nam is feasible, front-loaded for sustainability, has a higher proportion of investment on prevention, saves more lives and prevents more infections. Similarities in government and civil society rankings of criteria can create common grounds for future

Congregations are well positioned to address HIV in their communities, but their response to HIV has been mixed. An emerging literature describes HIV programming in urban, predominantly black congregations, but population-based data remain limited. This study examined the levels of HIV prevention and counseling programs and associated factors (e.g., religious, organizational) by using data from a phone census of congregations in the Greater Cincinnati area (N = 447). Over 10 % of congregations (36 % of Black Protestant and 5-18 % of other types of congregations) offered HIV education/prevention alone or in combination with counseling or with counseling and testing. Path analysis results showed notable significant (p theology-polity on HIV prevention/counseling programs, but these effects were fully mediated by other factors, including other community work and racial composition. The levels of HIV programming in this study were high by national standards, but further outreach is needed in high-risk African American communities.

Despite expanded programs for prevention of mother-to-child HIV transmission (PMTCT), HIV-infected infants may not be diagnosed until they are ill. Comparing HIV prevalence and outcomes in infants diagnosed in PMTCT programs to those in hospital settings may improve pediatric HIV diagnosis strategies. HIV-exposed infants turnaround time for tests were compared between PMTCT programs and hospital sites. Among the enrolled cohort, baseline characteristics, survival, and timing of antiretroviral therapy (ART) initiation were compared between infants diagnosed in PMTCT programs versus hospital. Among 1,923 HIV-exposed infants, HIV prevalence was higher among infants tested in hospital than PMTCT early infant diagnosis (EID) sites (41% vs. 11%, p 3 times as likely to die (HR = 3.1, 95% CI = 1.3-7.6). Among HIV-exposed infants, hospital-based testing was more likely to detect an HIV-infected infant than PMTCT testing. Because young symptomatic infants diagnosed with HIV during hospitalization have very high mortality, every effort should be made to diagnose HIV infections before symptom onset. Systems to expedite turnaround time at PMTCT EID sites and to routinize inpatient pediatric HIV testing are necessary to improve pediatric HIV outcomes.

Integrating HIV, hepatitis B and syphilis screening and treatment through the Maternal, Newborn and Child Health platform to reach global elimination targets

Full Text Available Every year, an estimated 180 000 babies in the Western Pacific Region are infected by hepatitis B, 13 000 by syphilis and 1400 by HIV through mother-to-child transmission.1 These infections can be largely prevented by antenatal screening, treatment and timely vaccination for newborns. Despite challenges in controlling each disease, major achievements have been made. National immunization programmes have reduced the regional hepatitis B prevalence from over 8% in 1990 to 0.93% among children born in 2012. In addition, HIV testing and treatment have helped keep the regional prevalence of HIV infections at 0.1%. In contrast, the number of maternal syphilis cases is still high in the Western Pacific Region, with an estimated 45 million cases in 2012. Elimination of mother-to-child transmission of these infections cannot be achieved through vertically applied programming and require using and augmenting to the shared Maternal, Newborn and Child Health platform to coordinate, integrate and enable cost efficiencies for these elimination efforts. The Regional Framework for Triple Elimination of Mother-to-Child Transmission of HIV, Hepatitis B and Syphilis in Asia and the Pacific 2018–2030 offers such a coordinated approach towards achieving the triple elimination of mother-to-child transmission of HIV, hepatitis B and syphilis and provides guidance for decision-makers, managers and health professionals working in programmes addressing maternal, newborn and child health, HIV, hepatitis, sexually transmitted infections and immunization.

Prevention of mother to child transmission of HIV remains a key public health priority in most developing countries. The provider Initiated Opt - Out Prenatal HIV Screening Approach, recommended by the World Health Organization (WHO) lately has been adopted and translated into policy in most Sub - Saharan African countries. To better ascertain the ethical reasons for or against the use of this approach, we carried out a literature review of the ethics literature. Papers published in English and French Languages between 1990 and 2015 from the following data bases were searched: Pubmed, Cochrane literature, Embase, Cinhal, Web of Science and Google Scholar. After screening from 302 identified relevant articles, 21 articles were retained for the critical review. Most authors considered this approach ethically justifiable due to its potential benefits to the mother, foetus and society (Beneficence). The breaching of respect for autonomy was considered acceptable on the grounds of libertarian paternalism. Most authors considered the Opt - Out approach to be less stigmatizing than the Opt - In. The main arguments against the Opt - Out approach were: non respect of patient autonomy, informed consent becoming a meaningless concept and the HIV test becoming compulsory, risk of losing trust in health care providers, neglect of social and psychological implications of doing an HIV test, risk of aggravation of stigma if all tested patients are not properly cared for and neglect of sociocultural peculiarities. The Opt - Out approach could be counterproductive in case gender sensitive issues within the various sociocultural representations are neglected, and actions to offer holistic care to all women who shall potentially test positive for HIV were not effectively ascertained. The Provider Initiated Opt - Out Prenatal HIV Screening option remains ethically acceptable, but deserves caution, active monitoring and evaluation within the translation of this approach into to practice.

We investigated the diagnostic usefulness of brain magnetic resonance imaging (MRI) screening in HIV-1-infected patients without neurological symptoms in detecting intracranial diseases at early stages. In this retrospective analysis, the study patients were HIV-1-infected patients who underwent brain MRI scan in clinical practice between 2001 and 2013. We excluded patients with MRI for (1) follow-up examination for prediagnosed intracranial diseases, (2) cancer staging, (3) screening mycobacterium/bacteria/fungi disease proliferation in the brain, and (4) evaluation for meningitis/encephalitis. The study patients (n=485) were classified into two groups: those who underwent brain MRI scan without any neurological symptoms/signs (asymptomatic patients, n=158) and those who underwent MRI due to such symptoms (symptomatic patients, n=327). Asymptomatic patients had lower CD4 counts than symptomatic patients (median 78 versus 241/μl). Intracranial diseases were detected in three (2%) of the asymptomatic patients [two toxoplasmosis and one progressive multifocal leukoencephalopathy (PML)] compared to 58 (19%) of the symptomatic patients (the χ(2) test, pHIV-associated dementia (n=17). Among symptomatic patients, intracranial diseases were common in those with slurred speech (3/6, 50%), seizure (4/10, 40%), eyesight/vision abnormality (5/16, 31%), altered mental status (8/31, 26%), and hemiplegia/numbness (13/50, 26%). For patients with CD4 count HIV-1-infected patients without neurological symptoms is of little value.

One in three new cases of HIV in South Africa is among adolescents. Given that adolescents are particularly affected, scalable, and cost-effective prevention programs are urgently needed. This study aims to identify opportunities to integrate technology into youth HIV prevention efforts. In 2012, 1107 8th-11th graders completed a paper-and-pencil survey. Respondents were enrolled in one of three public high schools in Langa, a lower income community in Cape Town, South Africa. Eighty-nine percent of respondents have used text messaging (SMS) and 86% have gone online. If an HIV prevention program was offered online, 66% of youth would be somewhat or extremely likely to access it; slightly fewer (55%) felt the same about SMS-based programming. In comparison, 85% said they would be somewhat or extremely likely to access a school-based HIV prevention program. Interest in Internet- (60%) and SMS-based (54%) HIV prevention programming was similar for youth who had a self-appraised risk of HIV compared to youth who appraised their risk to be lower, as it was for youth who were tired of hearing messages about HIV prevention. Technology use is common - even among high school students who live in lower income communities. At the same time, these data reveal that it is not uncommon for youth to be tired of hearing messages about HIV prevention, and many of the typical topics key to HIV prevention have low interest levels among youth. HIV prevention researchers need to be mindful of the extent of existing programming that youth are exposed to. Technology-based programming may be especially amenable to meeting these requirements because of its novelty especially in developing countries, and because interactive functionality can be easily integrated into the program design. Given the preference for school- and Internet-based programming, it seems that a hybrid approach is likely feasible and acceptable.

Human immunodeficiency virus (HIV) drugs designed to interfere with obligatory utilization of certain host cell factors by virus are less likely to encounter development of resistant strains than drugs directed against viral components. Several cellular genes required for productive infection by HIV were identified by the use of genetic suppressor element (GSE) technology as potential targets for anti-HIV drug development. Fragmented cDNA libraries from various pools of human peripheral blood mononuclear cells (PBMC) were expressed in vitro in human immunodeficiency virus type 1 (HIV-1)-susceptible cell lines and subjected to genetic screens to identify GSEs that interfered with viral replication. After three rounds of selection, more than 15 000 GSEs were sequenced, and the cognate genes were identified. The GSEs that inhibited the virus were derived from a diverse set of genes including cell surface receptors, cytokines, signaling proteins, transcription factors, as well as genes with unknown function. Approximately 2.5% of the identified genes were previously shown to play a role in the HIV-1 life cycle; this finding supports the biological relevance of the assay. GSEs were derived from the following 12 cell surface proteins: CXCR4, CCR4, CCR7, CD11C, CD44, CD47, CD68, CD69, CD74, CSF3R, GABBR1, and TNFR2. Requirement of some of these genes for viral infection was also investigated by using RNA interference (RNAi) technology; accordingly, 10 genes were implicated in early events of the viral life cycle, before viral DNA synthesis. Thus, these cell surface proteins represent novel targets for the development of therapeutics against HIV-1 infection and AIDS

In the United States, Lung Cancer is responsible for more cancer deaths than the next four cancers combined. In addition, the 5 year survival rate for lung cancer patients has not improved over the past 40 to 50 years. To combat this deadly disease, in 2002 the National Cancer Institute launched a very large Randomized Control Trial called the National Lung Screening Trial (NLST). This trial would randomize subjects who had substantial risk of lung cancer (due to age and smoking history) into either a Chest X-ray arm or a low dose CT arm. In November 2010, the National Cancer Institute announced that the NLST had demonstrated 20% fewer lung cancer deaths among those who were screened with low-dose CT than with chest X-ray. In December 2013, the US Preventive Services Task Force recommended the use of Lung Cancer Screening using low dose CT and a little over a year later (Feb. 2015), CMS announced that Medicare would also cover Lung Cancer Screening using low dose CT. Thus private and public insurers are required to provide Lung Cancer Screening programs using CT to the appropriate population(s). The purpose of this Symposium is to inform medical physicists and prepare them to support the implementation of Lung Screening programs. This Symposium will focus on the clinical aspects of lung cancer screening, requirements of a screening registry for systematically capturing and tracking screening patients and results (such as required Medicare data elements) as well as the role of the medical physicist in screening programs, including the development of low dose CT screening protocols. Learning Objectives: To understand the clinical basis and clinical components of a lung cancer screening program, including eligibility criteria and other requirements. To understand the data collection requirements, workflow, and informatics infrastructure needed to support the tracking and reporting components of a screening program. To understand the role of the medical physicist in

The purpose of this integrative literature review was to explore factors that are related to sexual practices among Latino adolescents and identify which of those factors are common across successful sexually transmitted infection (STI)/HIV intervention programs for Latino adolescents. An integrative literature review was conducted. Search terms included Latino, Hispanic, education, intervention/prevention programs, sex, sexuality, reproductive health, health risk behaviors, multiple sex partners, contraception, STI/HIV/AIDS, sexually transmitted diseases, delay in initiation of sexual intercourse, consistent use of birth control, avoidance of STI/HIV infections, unintended pregnancy, cultural factors, and gender roles. Findings revealed from the review of 17 articles addressing factors related to sexual practices among Latino adolescents included familialism, religion, gender roles, level of knowledge/information, and privacy/confidentiality. Five successful STI/HIV intervention programs, that incorporated those factors to effectively reduce risky sexual behaviors were identified. STI/HIV knowledge and gender roles were recognized as common factors integrated into and across successful intervention programs for this population. Only STI/HIV knowledge and gender roles were found as common factors across the five successful STI/HIV intervention programs and should be incorporated into future intervention programs that are culturally and gender specific. Therefore, health care providers need to understand culturally related gender roles and their impact on sexual practices to provide culturally sensitive and appropriate sex education about STIs and HIV for Latino adolescents to increase the program potential for reducing STI/HIV. © 2013 Wiley Periodicals, Inc.

Latin America and the Caribbean (LAC) have a significant burden of cervical cancer. Prophylactic human papillomavirus (HPV) vaccines are an opportunity for primary prevention and new screening methods, such as new HPV DNA testing, are promising alternatives to cytology screening that should be analyzed in the context of regional preventive programs. Cytology-based screening programs have not fulfilled their expectations and coverage does not sufficiently explain the lack of impact on screening in LAC. While improved evaluation of screening programs is necessary to increase the impact of screening on the reduction of incidence and mortality, other programmatic aspects will need to be addressed such as follow-up of positive tests and quality control. The implementation of new technologies might enhance screening performance and reduce mortality in the region. The characteristics, performance and impact of cervical cancer screening programs in LAC are reviewed in this article.

Background To estimate the incremental cost-effectiveness of amblyopia screening at preschool and kindergarten, we compared the costs and benefits of 3 amblyopia screening scenarios to no screening and to each other: (1) acuity/stereopsis (A/S) screening at kindergarten, (2) A/S screening at preschool and kindergarten, and (3) photoscreening at preschool and A/S screening at kindergarten. Methods We programmed a probabilistic microsimulation model of amblyopia natural history and response to treatment with screening costs and outcomes estimated from 2 state programs. We calculated the probability that no screening and each of the 3 interventions were most cost-effective per incremental quality-adjusted life year (QALY) gained and case avoided. Results Assuming a minimal 0.01 utility loss from monocular vision loss, no screening was most cost-effective with a willingness to pay (WTP) of less than $16,000 per QALY gained. A/S screening at kindergarten alone was most cost-effective between a WTP of $17,000 and $21,000. A/S screening at preschool and kindergarten was most cost-effective between a WTP of $22,000 and $75,000, and photoscreening at preschool and A/S screening at kindergarten was most cost-effective at a WTP greater than $75,000. Cost-effectiveness substantially improved when assuming a greater utility loss. All scenarios were cost-effective when assuming a WTP of $10,500 per case of amblyopia cured. Conclusions All 3 screening interventions evaluated are likely to be considered cost-effective relative to many other potential public health programs. The choice of screening option depends on budgetary resources and the value placed on monocular vision loss prevention by funding agencies. PMID:21877675

Syphilis continues to be a significant public health problem among HIV-positive men who have sex with men (MSM) internationally. This study aimed to determine whether the routine inclusion of syphilis serology with every blood test performed as part of HIV monitoring increases the detection of early asymptomatic syphilis among HIV-positive MSM. We examined the effect of this intervention, implemented in January 2007, on the detection of early asymptomatic syphilis among HIV-positive MSM attending the Melbourne Sexual Health Centre, Australia, and compared this with the previous clinic policy of annual syphilis screening. In the 18 months before and after the intervention, the median number of syphilis tests performed per man per year was 1 and 2, respectively. The proportion of MSM diagnosed with early syphilis who were asymptomatic was 21% (3 of 14) and 85% (41 of 48) for the 2 respective periods (P = 0.006). The time between the midpoint since last syphilis serology and diagnosis of syphilis was a median of 107 days (range 9-362) and 45 days (range 23-325) for the 2 periods, respectively (P = 0.018). The inclusion of routine syphilis serology with every blood test performed as part of HIV monitoring in HIV-positive MSM resulted in a large increase in the proportion of men diagnosed with early asymptomatic syphilis. This simple intervention probably also decreased the duration of infectiousness, enhancing syphilis control while also reducing morbidity.

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.

Background Tuberculosis (TB) and human immunodeficiency virus (HIV) represent two of the greatest health threats in African prisons. In 2010, collaboration between the Centre for Infectious Disease Research in Zambia, the Zambia Prisons Service, and the National TB Program established a TB and HIV screening program in six Zambian prisons. We report data on the prevalence of TB and HIV in one of the largest facilities: Lusaka Central Prison. Methods Between November 2010 and April 2011, we assessed the prevalence of TB and HIV amongst inmates entering, residing, and exiting the prison, as well as in the surrounding community. The screening protocol included complete history and physical exam, digital radiography, opt-out HIV counseling and testing, sputum smear and culture. A TB case was defined as either bacteriologically confirmed or clinically diagnosed. Results A total of 2323 participants completed screening. A majority (88%) were male, median age 31 years and body mass index 21.9. TB symptoms were found in 1430 (62%). TB was diagnosed in 176 (7.6%) individuals and 52 people were already on TB treatment at time of screening. TB was bacteriologically confirmed in 88 cases (3.8%) and clinically diagnosed in 88 cases (3.8%). Confirmed TB at entry and exit interventions were 4.6% and 5.3% respectively. Smear was positive in only 25% (n = 22) of bacteriologically confirmed cases. HIV prevalence among inmates currently residing in prison was 27.4%. Conclusion Ineffective TB and HIV screening programs deter successful disease control strategies in prison facilities and their surrounding communities. We found rates of TB and HIV in Lusaka Central Prison that are substantially higher than the Zambian average, with a trend towards concentration and potential transmission of both diseases within the facility and to the general population. Investment in institutional and criminal justice reform as well as prison-specific health systems is urgently required. PMID

Quality control in screening programs for cervical cancer

2012-01-01

The malignancy of the cervix is one of the few locations avoidable cancers, if detected before it progresses to the infiltration. The most efficient way of early detection is through a screening program to provide women undertaking a regular and quality Pap smear. If this test results abnormal, the program offers easier access to specialized care, effective treatment, and follow-up. The objective of this article is to present usefulness of methods for quality control used in screening programs for cervical cancer to detect their inadequacies. Here are some factors and conditions that must be considered in each of the steps to take, for a cervical cancer screening program to be successful and to meet the objectives proposed in reducing mortality due to this cause. This document contains some useful indexes calculated to ensure quality throughout the process. There should be the measurement of quality throughout the screening process that allows collecting of reliable data as well as correcting deficiencies

We aimed to describe the current and desired involvement of family physicians (FPs) in the treatment of HIV patients (screening practices, potential training and patient follow-up) to reduce the duration and frequency of their hospital treatment. We conducted a descriptive cross-sectional survey between 2011 and 2012 with the support of COREVIH (Regional Coordinating Committee on HIV). We sent a self-assessment questionnaire to all FPs of the Pays de la Loire region to enquire about their HIV screening practices and expectations for the management of HIV patients. A total of 871 FPs completed the questionnaire (response rate: 30.4%). A total of 54.2% said to provide care to HIV patients; the mean number of HIV patients per FP was estimated at 1.4. With regard to HIV screening, 12.2% systematically suggest an HIV serology to their patients and 72.7% always suggest it to pregnant women. About 45.4% of responding FPs said to be willing to manage HIV patients (clinical and biological monitoring, compliance checks and prescription renewal). FPs mainly reported the lack of training and the low number of HIV patients as a barrier to their further involvement in the management of HIV patients. The responding FPs provide care to very few HIV patients. They are, however, willing to be more involved in the routine care of these patients. Medical training provided by COREVIH would help improve HIV screening. The management of HIV patients could thus be handed over to willing FPs. Copyright © 2015. Published by Elsevier SAS.

The Ayoreo population constitutes one of Bolivia's most vulnerable ethnic groups in terms of HIV/AIDS. Being a woman, indigenous, and a sex worker signifies belonging to a high-risk group. The aim of this study is to explore the Ayoreo sex workers' and health agents' perceptions of HIV/AIDS prevention programs in order to identify variables that could influence their success or failure. This study used an ethnographic methodology that included participant observation and semistructured interviews. In the data collection, participant observation and semistructured interviews with sex workers and key informants were conducted. Three themes emerged from the inductive data analysis: health prevention efforts, cultural inadequacy of prevention programs, and the eventuality of interventions. We conclude that nursing can develop culturally-adequate HIV/AIDS prevention interventions and programs as well as promote health within these populations. © The Author(s) 2014.

Overcoming barriers in HPV vaccination and screening programs

Alex Vorsters

2017-12-01

Full Text Available The Human Papillomavirus Prevention and Control Board brought together experts to discuss optimizing HPV vaccination and screening programs.Board members reviewed the safety profile of licensed HPV vaccines based on clinical and post-marketing data, reaching a consensus that current safety data is reassuring.Successful vaccination programs used well-coordinated communication campaigns, integrating (social media to spread awareness. Communication of evidence supporting vaccine effectiveness had beneficial effects on the perception of the vaccine. However, anti-vaccination campaigns have threatened existing programs in many countries.Measurement and monitoring of HPV vaccine confidence over time could help understand the nature and scale of waning confidence, define issues and intervene appropriately using context-specific evidence-based strategies. Finally, a broad group of stakeholders, such as teachers, health care providers and the media should also be provided with accurate information and training to help support prevention efforts through enhanced understanding of the risks and benefits of vaccination.Similarly, while cervical cancer screening through population-based programs is highly effective, barriers to screening exist: awareness in countries with population-based screening programs, access for vulnerable populations, and access and affordability in low- and middle-income countries. Integration of primary and secondary prevention has the potential to accelerate the decrease in cervical cancer incidence.

Lung cancer screening may provide a "teachable moment" for promoting smoking cessation. This study assessed smoking cessation and relapse rates among individuals undergoing follow-up low-dose chest computed tomography (CT) in a clinical CT lung screening program and assessed the influence of initial screening results on smoking behavior. Self-reported smoking status for individuals enrolled in a clinical CT lung screening program undergoing a follow-up CT lung screening exam between 1st February, 2014 and 31st March, 2015 was retrospectively reviewed and compared to self-reported smoking status using a standardized questionnaire at program entry. Point prevalence smoking cessation and relapse rates were calculated across the entire population and compared with exam results. All individuals undergoing screening fulfilled the National Comprehensive Cancer Network Clinical Practice Guidelines in Oncology: Lung Cancer Screening v1.2012(®) high-risk criteria and had an order for CT lung screening. A total of 1,483 individuals underwent a follow-up CT lung screening exam during the study interval. Smoking status at time of follow-up exam was available for 1,461/1,483 (98.5%). A total of 46% (678/1,461) were active smokers at program entry. The overall point prevalence smoking cessation and relapse rates were 20.8% and 9.3%, respectively. Prior positive screening exam results were not predictive of smoking cessation (OR 1.092; 95% CI, 0.715-1.693) but were predictive of reduced relapse among former smokers who had stopped smoking for 2 years or less (OR 0.330; 95% CI, 0.143-0.710). Duration of program enrollment was predictive of smoking cessation (OR 0.647; 95% CI, 0.477-0.877). Smoking cessation and relapse rates in a clinical CT lung screening program rates are more favorable than those observed in the general population. Duration of participation in the screening program correlated with increased smoking cessation rates. A positive exam result correlated with reduced

OBJECTIVE--The aim of this study was to assess the prevalence of syphilis, human immunodeficiency virus (HIV), and hepatitis B virus (HBV) infections in women at the time of delivery, and to determine the seroconversion rates for syphilis and HIV infections from initial booking visit to delivery. SETTING--The labour ward of a typical tertiary hospital in a developing country and serving an indigent African population. METHOD--Four hundred and eighteen women presenting in labour were randomly selected and informed consent obtained for serological testing for syphilis and HBV infections in umbilical cord blood samples. The specimens were then given a study number, the gestational ages recorded and anonymously tested for HIV infection. RESULTS--Of the 191 women who had antenatal care, 13 (6.8%) were HIV antibody positive at the initial "booking" visit. An additional 4 were found to be HIV antibody positive at the time of delivery resulting in a seroconversion rate of 2.2%. The seroconversion rate for syphilis at the time of delivery was 2.7%. Hepatitis B surface antigens were detected in only 2 women, one of whom was antigen positive. CONCLUSION--The high seroconversion rates for both syphilis and HIV infection in pregnancy justifies re-screening for these conditions in endemic areas such as ours. PMID:7744414

To describe HIV testing uptake and prevalence among adolescents and adults in a home-based HIV counseling and testing program in western Kenya. Since 2007, the Academic Model Providing Access to Healthcare program has implemented home-based HIV counseling and testing on a large scale. All individuals aged ≥13 years were eligible for testing. Data from 5 of 8 catchments were included in this analysis. We used descriptive statistics and multivariate logistic regression to examine testing uptake and HIV prevalence among adolescents (13-18 years), younger adults (19-24 years), and older adults (≥25 years). There were 154,463 individuals eligible for analyses as follows: 22% adolescents, 19% younger adults, and 59% older adults. Overall mean age was 32.8 years and 56% were female. HIV testing was high (96%) across the following 3 groups: 99% in adolescents, 98% in younger adults, and 94% in older adults (P < 0.001). HIV prevalence was higher (11.0%) among older adults compared with younger adults (4.8%) and adolescents (0.8%) (P < 0.001). Those who had ever previously tested for HIV were less likely to accept HIV testing (adjusted odds ratio: 0.06, 95% confidence interval: 0.05 to 0.07) but more likely to newly test HIV positive (adjusted odds ratio: 1.30, 95% confidence interval: 1.21 to 1.40). Age group differences were evident in the sociodemographic and socioeconomic factors associated with testing uptake and HIV prevalence, particularly, gender, relationship status, and HIV testing history. Sociodemographic and socioeconomic factors were independently associated with HIV testing and prevalence among the age groups. Community-based treatment and prevention strategies will need to consider these factors.

The Laboratory Diagnosis of HIV Infections

Directory of Open Access Journals (Sweden)

Margaret Fearon

2005-01-01

Full Text Available HIV diagnostic testing has come a long way since its inception in the early 1980s. Current enzyme immunoassays are sensitive enough to detect antibody as early as one to two weeks after infection. A variety of other assays are essential to confirm positive antibody screens (Western blot, polymerase chain reaction [PCR], provide an adjunct to antibody testing (p24 antigen, PCR, or provide additional information for the clinician treating HIV-positive patients (qualitative and quantitative PCR, and genotyping. Most diagnostic laboratories have complex testing algorithms to ensure accuracy of results and optimal use of laboratory resources. The choice of assays is guided by the initial screening results and the clinical information provided by the physician; both are integral to the laboratory's ability to provide an accurate laboratory diagnosis. Laboratories should also provide specific information on specimen collection, storage and transport so that specimen integrity is not compromised, thereby preserving the accuracy of laboratory results. Point of Care tests have become increasingly popular in the United States and some places in Canada over the past several years. These tests provide rapid, on-site HIV results in a format that is relatively easy for clinic staff to perform. However, the performance of these tests requires adherence to good laboratory quality control practices, as well as the backup of a licensed diagnostic laboratory to provide confirmation and resolution of positive or indeterminate results. Laboratory quality assurance programs and the participation in HIV proficiency testing programs are essential to ensure that diagnostic laboratories provide accurate, timely and clinically relevant laboratory results.

2010-04-01

This study measured audience reactions and receptivity to five draft HIV prevention messages developed for people living with HIV (PLWH) to inform future HIV message choice and audience targeting decisions. Our premise was that message concepts that receive wide audience appeal constitute a strong starting point for designing future HIV prevention messages, program activities, and health communication and marketing campaigns for PLWH. The majority of participants indicated agreement with evaluative statements that expressed favorable attitudes toward all five of the message concepts we evaluated. Participants gave the lowest approval to the message promoting sero-sorting. Sociodemographic characteristics played less of a role in predicting differences in message perceptions than attitudes, beliefs and sexual behavior. The general appeal for these messages is encouraging given that messages were expressed in plain text without the support of other creative elements that are commonly used in message execution. These results confirm the utility of systematic efforts to generate and screen message concepts prior to large-scale testing.

We sought to quantify change in HIV knowledge in three rural Nigerian villages following an integrated culturally adapted and technology assisted educational intervention. Methods A prospective 14-week cohort study was designed to compare short-term changes in HIV knowledge between seminar-based education program and a novel program, which capitalized on the rural culture of small-group oral learning and was delivered by portable digital-audio technology. Results Participants were mostly Moslem (99%, male (53.5%, with no formal education (55%. Baseline HIV knowledge was low ( Conclusions Baseline HIV-awareness was low. Culturally adapted, technology-assisted HIV education program is a feasible cost-effective method of raising HIV awareness among low-literacy rural communities.

Reducing HIV risk among transgender women in Thailand: a quasi-experimental evaluation of the sisters program.

Duangta Pawa

Full Text Available Transgender women are particularly at risk of HIV infection, but little evidence exists on effective HIV prevention strategies with this population. We evaluated whether Sisters, a peer-led program for transgender women, could reduce HIV risks in Pattaya, Thailand. The study used time-location sampling to recruit 308 transgender women in Pattaya into a behavioral survey in 2011. Coarsened exact matching was used to create statistically equivalent groups of program participants and non-participants, based on factors influencing likelihood of program participation. Using multivariable logistic regression, we estimated effects of any program participation and participation by delivery channel on: condom use at last sex; consistent condom and condom/water-based lubricant use in the past 3 months with commercial, casual, and regular partners; and receipt of HIV testing in the past 6 months. Program coverage reached 75% of the population. In a matched sub-sample (n = 238, participation in outreach was associated with consistent condom/water-based lubricant use with commercial partners (AOR 3.22, 95% CI 1.64-6.31. Attendance at the Sisters drop-in center was associated with receiving an HIV test (AOR 2.58, 95% CI 1.47-4.52. Dedicated transgender-friendly programs are effective at reducing HIV risks and require expansion to better serve this key population and improve HIV prevention strategies.

Background To eliminate new pediatric HIV infections, interventions that facilitate adherence, including those that minimize stigma, enhance social support, and mitigate the influence of poverty, will likely be required in addition to combination antiretroviral therapy (ART). We examined the relationship between partner testing and infant outcome in a prevention of parent-to-child transmission of HIV program, which included a family-centered case management approach and a supportive environment for partner disclosure and testing. Design We analyzed routinely collected data for women and infants who enrolled in the parent-to-child transmission of HIV program at Goroka Family Clinic, Eastern Highlands Provincial Hospital, Papua New Guinea, from 2007 through 2011. Results Two hundred and sixty five women were included for analysis. Of these, 226 (85%) had a partner, 127 (56%) of whom had a documented HIV test. Of the 102 HIV-infected partners, 81 (79%) had been linked to care. In adjusted analyses, we found a significantly higher risk of infant death, infant HIV infection, or loss to follow-up among mother–infant pairs in which the mother reported having no partner or a partner who was not tested or had an unknown testing status. In a second multivariable analysis, infants born to women with more time on ART or who enrolled in the program in later years experienced greater HIV-free survival. Conclusions In a program with a patient-oriented and family-centered approach to prevent vertical HIV transmission, the majority of women's partners had a documented HIV test and, if positive, linkage to care. Having a tested partner was associated with program retention and HIV-free survival for infants. Programs aiming to facilitate diagnosis disclosure, partner testing, and linkage to care may contribute importantly to the elimination of pediatric HIV. PMID:25172429

PEPFAR, national governments, and other stakeholders are investing unprecedented resources to provide HIV treatment in developing countries. This study reports empirical data on costs and cost trends in a large sample of HIV treatment sites. In 2006–2007, we conducted cost analyses at 43 PEPFAR-supported outpatient clinics providing free comprehensive HIV treatment in Botswana, Ethiopia, Nigeria, Uganda, and Vietnam. We collected data on HIV treatment costs over consecutive 6-month periods from scale-up of dedicated HIV treatment services at each site. The study included all patients receiving HIV treatment and care at study sites (62,512 ART and 44,394 pre-ART patients). Outcomes were costs per-patient and total program costs, subdivided by major cost categories. Median annual economic costs were $202 (2009 USD) for pre-ART patients and $880 for ART patients. Excluding ARVs, per-patient ART costs were $298. Care for newly initiated ART patients cost 15–20% more than for established patients. Per-patient costs dropped rapidly as sites matured, with per-patient ART costs dropping 46.8% between first and second 6-month periods after the beginning of scale-up, and an additional 29.5% the following year. PEPFAR provided 79.4% of funding for service delivery, and national governments provided 15.2%. Treatment costs vary widely between sites, and high early costs drop rapidly as sites mature. Treatment costs vary between countries and respond to changes in ARV regimen costs and the package of services. While cost reductions may allow near-term program growth, programs need to weigh the trade-off between improving services for current patients and expanding coverage to new patients. PMID:21412127

Full Text Available Abstract The eruption of Kaposi sarcoma (KS and aggressive non-Hodgkin lymphoma (NHL in young homosexual men in 1981 in the West heralded the onset of the human immunodeficiency virus (HIV infection epidemic, which remains one of the biggest challenges to global public health and science ever. Because KS and NHL were increased >10,000 and 50-600 times, respectively, with HIV, they were designated AIDS defining cancers (ADC. Cervical cancer (CC, increased 5-10 times was also designated as an ADC. A few other cancers are elevated with HIV, including Hodgkin lymphoma (10 times, anal cancer (15-30 times, and lung cancer (4 times are designated as non-AIDS defining cancers (NADCs. Since 1996 when combination antiretroviral therapy (cART became widely available in the West, dramatic decreases in HIV mortality have been observed and substantial decrease in the incidence of ADCs. Coincidentally, the burden of NADCs has increased as people with HIV age with chronic HIV infection. The impact of HIV infection on cancer in sub-Saharan Africa, where two thirds of the epidemic is concentrated, remains poorly understood. The few studies conducted indicate that risks for ADCs are also increased, but quantitatively less so than in the West. The risks for many cancers with established viral associations, including liver and nasopharynx, which are found in Africa, do not appear to be increased. These data are limited because of competing mortality, and cancer is under diagnosed, pathological confirmation is rare, and cancer registration not widely practiced. The expansion of access to life-extending cART in sub-Saharan Africa, through programs such as the Global Fund for AIDS, Malaria, and Tuberculosis and the US President's Emergency Program for AIDS Relief (PEPFAR, is leading to dramatic lengthening of life of HIV patients, which will likely influence the spectrum and burden of cancer in patients with HIV. In this paper, we review current literature and explore

Full Text Available Purpose: Integrated counselling and testing centres (ICTC provide counselling and blood testing facilities for HIV diagnosis. Oral fluid tests provide an alternative for people whodo not want blood to be drawn. Also, it avoids the risk of occupational exposure. The goal of this study was to evaluate the utility of Calypte AWARE HIV-1/2 OMT antibody test as a screening test in an Indian setting. Materials and Methods: A cross-sectional study was carried out after ethics committee approval in 250 adult ICTC clients. Blood was collected and tested from these clients for HIV diagnosis as per routine policy and the results were considered as the gold standard. Also, after another written informed consent, oral fluid was collected from the clients and tested for the presence of HIV antibodies. Twenty five clients who had and 25 clients who had not completed their secondary school education (Group A and Group B, respectively were also asked to perform and interpret the test on their own and their findings and experiences were noted. Result: The sensitivity, specificity, PPV and NPV of the oral fluid antibody test were 100%, 98.51%, 94.11% and 100%, respectively. Seventy six percent of clients preferred oral fluid testing. Group B found it difficult to perform the test as compared to Group A and this difference was statistically significant (P ≤ 0.05. Conclusion: Oral fluid testing can be used as a screening test for HIV diagnosis; however, confirmation of reactive results by blood-based tests is a must.

This paper reports the results of a mobile screening mammography program offered to employees of a large corporation. The examination was available to women 35 or older. Women were charged $30 for a standard two-view examination; the remaining costs were underwritten by the employer. In the first year of the program 3,627 examination were performed; 63 biopsies were recommended. To date, 54 biopsies have been completed. Nine cancers were identified; seven state I and two stage II cancers were diagnosed. The distribution and prevalence rates were similar to (slightly higher than) statewide statistics. Mobile screening programs conducted at the worksite provide an inexpensive convenient alternation to more traditional screening programs. The inherent advantages of this program are the low cost, relative ease with which the examination can be obtained, and the positive role that corporate medical personnel assume in encouraging participation

Full Text Available Community mobilizing strategies are essential to health promotion and uptake of HIV prevention. However, there has been little conceptual work conducted to establish the core components of community mobilization, which are needed to guide HIV prevention programming and evaluation.We aimed to identify the key domains of community mobilization (CM essential to change health outcomes or behaviors, and to determine whether these hypothesized CM domains were relevant to a rural South African setting.We studied social movements and community capacity, empowerment and development literatures, assessing common elements needed to operationalize HIV programs at a community level. After synthesizing these elements into six essential CM domains, we explored the salience of these CM domains qualitatively, through analysis of 10 key informant in-depth-interviews and seven focus groups in three villages in Bushbuckridge.CM DOMAINS INCLUDE: 1 shared concerns, 2 critical consciousness, 3 organizational structures/networks, 4 leadership (individual and/or institutional, 5 collective activities/actions, and 6 social cohesion. Qualitative data indicated that the proposed domains tapped into theoretically consistent constructs comprising aspects of CM processes. Some domains, extracted from largely Western theory, required little adaptation for the South African context; others translated less effortlessly. For example, critical consciousness to collectively question and resolve community challenges functioned as expected. However, organizations/networks, while essential, operated differently than originally hypothesized - not through formal organizations, but through diffuse family networks.To date, few community mobilizing efforts in HIV prevention have clearly defined the meaning and domains of CM prior to intervention design. We distilled six CM domains from the literature; all were pertinent to mobilization in rural South Africa. While some adaptation of

The identification of HIV-positive patients who exhibit criteria for Posttraumatic Stress Disorder (PTSD) and related trauma symptomatology is of clinical importance in the maintenance of their overall wellbeing. This study assessed the sensitivity and specificity of the 17-item Posttraumatic Stress Diagnostic Scale (PDS), a self-report instrument, in the detection of HIV-related PTSD. An adapted version of the PTSD module of the Composite International Diagnostic Interview (CIDI) served as the gold standard. 85 HIV-positive patients diagnosed with HIV within the year preceding data collection were recruited by means of convenience sampling from three HIV clinics within primary health care facilities in the Boland region of South Africa. A significant association was found between the 17-item PDS and the adapted PTSD module of the CIDI. A ROC curve analysis indicated that the 17-item PDS correctly discriminated between PTSD caseness and non-caseness 74.9% of the time. Moreover, a PDS cut-off point of > or = 15 yielded adequate sensitivity (68%) and 1-specificity (65%). The 17-item PDS demonstrated a PPV of 76.0% and a NPV of 56.7%. The 17-item PDS can be used as a brief screening measure for the detection of HIV-related PTSD among HIV-positive patients in South Africa.

Adolescents and young adults in sub-Saharan Africa (SSA) are particularly vulnerable to human immunodeficiency virus (HIV) and acquired immune deficiency syndrome (AIDS) infection. Adolescents orphaned as a direct result of HIV/AIDS are at an elevated risk of acquiring HIV/AIDS and other sexually transmitted infections. However, limited empirical evidence exists on HIV knowledge and prevention programs, especially those designed to address HIV information gaps among adolescents. This study evaluates the effect of a peer mentorship program provided in addition to other supportive services on HIV/AIDS knowledge, beliefs, and prevention attitudes, among school-going orphaned adolescents in southern Uganda. We utilize data from the Bridges to the Future Study, a 5-year longitudinal randomized experimental study funded by the National Institute of Child Health and Human Development. Out of the 1410 adolescents enrolled in the study (average age = 12.7 at study initiation), 855 of them participated in a nine-session, curriculum based peer mentorship program. We analyzed data collected at baseline and 12-months post intervention initiation. The results from bivariate and regression analysis indicate that, controlling for socioeconomic characteristics, adolescents who participated in a peer mentorship program were more likely than non-participants to report increased scores on HIV/AIDS knowledge(b = .86, 95%CI = .47 – 1.3, p ≤ .001); better scores on desired HIV/AIDS-related beliefs (b = .29, 95%CI = .06 – .52, p ≤ .01); and better scores on HIV/AIDS prevention attitudes (b = .76, 95%CI = .16 – 1.4, p ≤ .01). Overall, the study findings point to the potential role a of peer mentorship program in promoting the much-desired HIV/AIDS knowledge, beliefs, and prevention attitudes among orphaned adolescents. Future programs and policies that support AIDS-orphaned adolescents in sub-Saharan Africa should consider incorporating peer mentoring programs that provide

To describe the uptake of and factors associated with HIV prevalence among pregnant women in a large-scale home-based HIV counseling and testing (HBCT) program in western Kenya. In 2007, the Academic Model Providing Access to Healthcare Program (AMPATH) initiated HBCT to all individuals aged ≥13 years and high-risk children HIV prevalence. There were 119,678 women eligible for analysis; median age 25 (interquartile range, IQR: 18-34) years. Of these, 7,396 (6.2%) were pregnant at the time of HBCT; 4,599 (62%) had ever previously tested for HIV and 2,995 (40.5%) had not yet attended ANC for their current pregnancy. Testing uptake among pregnant women was high (97%). HBCT newly identified 241 (3.3%) pregnant HIV-positive women and overall HIV prevalence among all pregnant women was 6.9%. HIV prevalence among those who had attended ANC in this pregnancy was 5.4% compared to 9.0% among those who had not. Pregnant women were more likely to newly test HIV-positive in HBCT if they had not attended ANC in the current pregnancy (AOR: 6.85, 95% CI: 4.49-10.44). Pregnant women who had never attended ANC were about 6 times more likely to newly test HIV-positive compared to those who had attended ANC, suggesting that the cascade of services for prevention of mother-to-child HIV transmission should optimally begin at the home and village level if elimination of perinatal HIV transmission is to be achieved.

Female sex workers (FSWs) in Ghana have a 10-fold greater risk for acquiring HIV than the general adult population, and they contribute a substantial proportion of the new HIV infections in the country. Although researchers have conducted behavioral and biological surveys, there has been no review of the contextual, programmatic, and epidemiological changes over time. The authors conducted a historical review of HIV prevention programs in Ghana. We reviewed the use of different interventions for HIV prevention among FSWs and data from program monitoring and Integrated Biological and Behavioral Surveillance Surveys. In particular, we looked at changes in service access and coverage, the use of HIV testing and counseling services, and the changing prevalence of HIV and other sexually transmitted infections. HIV prevention interventions among FSWs increased greatly between 1987 and 2013. Only 72 FSWs were reached in a pilot program in 1987, whereas 40,508 FSWs were reached during a national program in 2013. Annual condom sales and the proportion of FSWs who used HIV testing and counseling services increased significantly, whereas the prevalence of gonorrhea and chlamydia decreased. The representation of FSWs in national HIV strategic plans and guidelines also improved. Ghana offers an important historical example of an evolving HIV prevention program that-despite periods of inactivity-grew in breadth and coverage over time. The prevention of HIV infections among sex workers has gained momentum in recent years through the efforts of the national government and its partners-a trend that is critically important to Ghana's future.

Financing for newborn screening is different from virtually all other public health programs. All except 5 screening programs collect fees as the primary source of program funding. A fee-based approach to financing newborn screening has been adopted by most states, to ensure consistent funding for this critical public health activity. Two types of data are reported here, ie, primary data from a survey of 37 state public health agencies and findings from exploratory case studies from 7 states. Most of the programs that participated in this survey (73%) reported that their newborn screening funding increased between 2002 and 2005, typically through increased fees and to a lesser extent through Medicaid, Title V Maternal and Child Health Services Block Grant, and state general revenue funding. All of the responding states that collect fees (n = 31) use such funds to support laboratory expenses, and most (70%) finance short-term follow-up services and program management. Nearly one half (47%) finance longer-term follow-up services, case management, or family support beyond diagnosis. Other states (43%) finance genetic or nutritional counseling and formula foods or treatment. Regardless of the source of funds, the available evidence indicates that states are committed to maintaining their programs and securing the necessary financing for the initial screening through diagnosis. Use of federal funding is currently limited; however, pressure to provide dedicated federal funding would likely increase if national recommendations for a uniform newborn screening panel were issued.

Controversy surrounds the linkage of prevention counseling with emergency department (ED)-based HIV testing. Further, the effectiveness and feasibility of prevention counseling in the ED setting is unknown. We investigate these issues by conducting a preliminarily exploration of several related aspects of our ED's HIV prevention counseling and testing program. Our urban, academic ED provides formal client-centered prevention counseling in conjunction with HIV testing. Five descriptive, exploratory observations were conducted, involving surveys and analysis of electronic medical records and programmatic data focused on (1) patient perception and feasibility of prevention counseling in the ED, (2) patient perceptions of the need to link prevention counseling with testing, and (3) potential effectiveness of providing prevention counseling in conjunction with ED-based HIV testing. Of 110 ED patients surveyed after prevention counseling and testing, 98% believed privacy was adequate, and 97% reported that their questions were answered. Patients stated that counseling would lead to improved health (80%), behavioral changes (72%), follow-up testing (77%), and discussion with partners (74%). However, 89% would accept testing without counseling, 32% were willing to seek counseling elsewhere, and 26% preferred not to receive the counseling. Correct responses to a 16-question knowledge quiz increased by 1.6 after counseling (95% confidence interval 1.3 to 12.0). The program completed counseling for 97% of patients tested; however, 6% of patients had difficulty recalling the encounter and 13% denied received testing. Among patients undergoing repeated testing, there was no consistent change in self-reported risk behaviors. Participants in the ED prevention counseling and testing program considered counseling acceptable and useful, though not required. Given adequate resources, prevention counseling can be provided in the ED, but it is unlikely that all patients benefit

With the increasing growth of HIV positive people the use of information and communication technologies (ICT) can play an important role in controlling the spread of the AIDS. Web and Mobile are the new technologies that young people take advantage from them. In this study a review to investigate the web and mobile based HIV prevention and intervention programs was carried out. A scoping review was conducted including PubMed, Science direct, Web of Science and Proquest to find relevant sources that published in 2009 to 2016. To identify published, original research that reported the web and mobile-based HIV prevention and intervention programs, an organized search was conducted with the following search keywords in combination: HIV, AIDS, m-Health, Mobile phone, Cell phone, Smartphone, Mobile health, internet, and web. Using the employed strategies, 173 references retrieved. Searched articles were compared based on their titles and abstracts. To identify duplicated articles, the title and abstracts were considered and 101 duplicated references were excluded. By going through the full text of related papers, 35 articles were found to be more related to the questions of this paper from which 72 final included. The advantages of web and mobile-based interventions include the possibility to provide constancy in the delivery of an intervention, impending low cost, and the ability to spread the intervention to an extensive community. Online programs such as Chat room-based Education program, Web-based therapeutic education system, and Online seek information can use for HIV/AIDS prevention. To use of mobile for HIV/AIDS prevention and intervention, programs including in: Health system focused applications, Population health focused applications, and Health messaging can be used.

HIV-associated neurocognitive disorders (HAND) are frequently occurring comorbidities in HIV-positive patients, diagnosed by means of a neuropsychological assessment (NPA). Due to the magnitude of the HIV-positive population in Sub-Saharan Africa, easy-to-use cognitive screening tools are essential. This was a cross-sectional clinical trial involving 44 HIV-positive patients (on stable cART) and 73 HIV-negative controls completing an NPA, the International HIV Dementia Scale (IHDS), and a culturally appropriate cognitive screening tool, the Montreal Cognitive Assessment-Basic (MoCA-B). HAND were diagnosed by calculating Z-scores using internationally published normative data on NPA, as well as by using data from the HIV-negative group to validate the MoCA-B. One hundred and seventeen patients were included (25% male, median age 35 years, median 11 years of education). A moderate correlation was found between the MoCA-B and NPA total Z-score (Pearson's r=0.36, p=0.02). Area under the curve (AUC) values for MoCA-B and IHDS were 0.59 and 0.70, respectively. The prevalence of HAND in HIV-positive patients was 66% when calculating Z-scores using published normative data versus 48% when using the data from the present HIV-negative cohort. The MoCA-B appeared not to be a valid screening tool for HAND in this setting. The prevalence of HAND in this setting is high, but appeared overestimated when using published norms.

To gather epidemiologic information on the spread of human immunodeficiency virus (HIV)-2 in Portugal, sera were collected in 1985 from 156 healthy adults currently living in Portugal but natives of Guinea Bissau, Cape Verde Islands, Saint Tome/Prince, Angola, and Mozambique and from 321 native Portuguese men and women who had close contact with local African populations. As a control, sera were collected from 102 health Portuguese with no previous contact with Africa or African natives. The enzyme-linked immunosorbent assay (ELISA) developed by Diagnostic Pasteur was used to screen for antibodies to HIV. No positive reactions were recorded in the control population. In contracts, 9 (6%) of the African natives and 7 (2%) of the contacts of Africans were HIV-positive, 6 of the positive sera were from women and 10 were from men. Significantly, 1 of the HIV-2-positive serum samples was from a native of Mozambique and 3 were from natives of Angola. This suggests that HIV-2 infection may have spread to other former Portuguese colonies, and foreign army soldiers who were at 1 time residents of Mozambique or Angola should be considered a risk group capable of spreading HIV-2 infection to other countries.

Full Text Available Hearing loss is the third most common condition affecting adults over 65 (Cruickshanks et al., 1998. It can affect quality of life, limiting the ability to communicate efficiently, and leading to isolation, psychological strain, and functional decline (LaForge, Spector, Sternberg, 1992; Yueh, Shapiro, MacLean, Shekelle, 2003. Communication limitations impinge on the person directly, as well as the family, friends, and social circle. Reports on hearing loss among adults indicate that less than 25% of people who can benefit from amplification are actually using hearing aids, and that people diagnosed with a hearing loss delay seeking amplification by about seven years (Kochkin, 1997. Often, family members are the driving force behind a person with a hearing loss who decides to seek help. Adult hearing screening programs might have a positive effect on raising public awareness on hearing loss and its implications, and shortening delay time for intervention. There is no routine hearing screening for the adult population in Cyprus. The health system provides hearing tests for beneficiaries upon physician recommendation or self-referral.

Full Text Available Abstract Background Although various HIV prevention programs targeting men who have sex with men (MSM are operating in China, whether and how these programs are being utilized is unclear. This study explores participation of HIV prevention programs and influencing factors among MSM in two cities in China. Methods This is a mixed-method study conducted in Beijing and Chongqing. A qualitative study consisting of in-depth interviews with 54 MSM, 11 key informants, and 8 focus group discussions, a cross-sectional survey using respondent-driven sampling among 998 MSM were conducted in 2009 and 2010 respectively to elicit information on MSM’s perception and utilization of HIV prevention programs. Qualitative findings were integrated with quantitative multivariate factors to explain the quantitative findings. Results Fifty-six percent of MSM in Chongqing and 75.1% in Beijing ever participated in at least one type of HIV prevention program (P=0.001. Factors related to participation in HIV prevention programs included age, ethnicity, income, HIV risk perception, living with boyfriend, living in urban area, size of MSM social network, having talked about HIV status with partners, and knowing someone who is HIV positive. Reasons why MSM did not participate in HIV prevention programs included logistical concerns like limited time for participation and distance to services; program content and delivery issues such as perceived low quality services and distrust of providers; and, cultural issues like HIV-related stigma and low risk perception. Conclusions The study shows that there is much room for improvement in reaching MSM in China. HIV prevention programs targeting MSM in China may need to be more comprehensive and incorporate the cultural, logistic and HIV-related needs of the population in order to effectively reach and affect this population’s risk for HIV.

The November 2016 general election and subsequent voting of the Electoral College resulted in the selection of Donald Trump as President of the United States. The incoming Administration ran a campaign that indicated a desire for substantial change in health policy, including the repeal of the Affordable Care Act (ACA). President Trump has said very little directly about HIV programs and policies, but some campaign positions (such as the repeal of the ACA) would clearly and substantially impact the lives of persons living with HIV. In this editorial, we highlight important HIV-related goals to which we must recommit ourselves, and we underscore several key points about evidence-based advocacy that are important to revisit at any time (but most especially when there is a change in Administration).

Background and Objectives Serologic screening for the major transfusion transmissible viruses (TTV) is critical to blood safety and has been widely implemented. However, actual performance as measured by proficiency testing has not been well studied in Sub-Saharan Africa. Therefore, we conducted an external quality assessment of laboratories engaged in transfusion screening in the region. Materials and Methods Blinded test panels, each comprising 25 serum samples that were pedigreed for HIV, HBsAg, HCV and negative status, were sent to participating laboratories. The panels were tested using the laboratories’ routine donor screening methods and conditions. Sensitivity and specificity were calculated and multivariable analysis was used to compare performance against mode of testing, country and infrastructure. Results A total of 12 African countries and 44 laboratories participated in the study. The mean (range) sensitivities for HIV, HBsAg and HCV were 91.9% (14.3-100), 86.7% (42.9-100) and 90.1% (50-100), respectively. Mean specificities for HIV, HBsAg and HCV were 97.7%, 97% and 99.5% respectively. After adjusting for country and infrastructure, rapid tests had significantly lower sensitivity than enzyme immunoassays (EIA) for both HBsAg (p<0.0001) and HCV (p<0.05). Sensitivity also varied by country and selected infrastructure variables. Conclusion While specificity was high, sensitivity was more variable and deficient in a substantial number of testing laboratories. These findings underscore the importance of proficiency testing and quality control, particularly in Africa where TTV prevalence is high. PMID:25052195

HIV prevalence remains high in Cambodia among female entertainment and sex workers (FESW), and amphetamine-type stimulant (ATS) use significantly increases risk of infection. A successful continuum of care (CoC) is key to effective clinical care and prevention. This study aimed to describe the HIV CoC in HIV-positive FESW. We examined CoC outcomes among HIV-positive FESW participating in the Cambodia Integrated HIV and Drug Prevention Implementation (CIPI) study, being implemented in ten provinces. CIPI is a trial aimed at reducing ATS use concomitant with the SMARTgirl HIV prevention program. From 2013 to 2016, 1198 FESW ≥ 18 years old who reported multiple sex partners and/or transactional sex were recruited. We identified 88 HIV-positive women at baseline. We described linkage to care as 12-month retention and viral suppression (HIV-positive women was 32 years [interquartile range (IQR) 28, 35]; 50% were working in entertainment venues and 50% as freelance sex workers; 70% reported SMARTgirl membership. In the past 3 months, women reported a median of 15 sex partners, 38% reported unprotected sex, and 55% reported using ATS. Overall, 88% were receiving HIV care, 83% were on antiretroviral therapy, 39% were retained in care at 12 months, and 23% were virally suppressed. SMARTgirl membership was independently associated with fourfold greater odds of 12-month retention in care (AOR = 4.16, 95% CI 1.38, 12.56). Those at high risk for an ATS use disorder had 91% lower odds of 12-month retention in care (AOR = 0.09, 95% CI 0.01, 0.72). Viral suppression was independently associated with SMARTgirl membership, older age, reporting of STI symptoms, worse symptoms of psychological distress, and greater numbers of sex partners. This is the first study to characterize the HIV CoC in Cambodian FESW. While most women were successfully linked to HIV care, retention and viral suppression were low. Tailored programs like SMARTgirl, targeting the broader population of

IMPORTANCE Newborn screening for severe combined immunodeficiency (SCID) using assays to detect T-cell receptor excision circles (TRECs) began in Wisconsin in 2008, and SCID was added to the national recommended uniform panel for newborn screened disorders in 2010. Currently 23 states, the District of Columbia, and the Navajo Nation conduct population-wide newborn screening for SCID. The incidence of SCID is estimated at 1 in 100 000 births. OBJECTIVES To present data from a spectrum of SCID newborn screening programs, establish population-based incidence for SCID and other conditions with T-cell lymphopenia, and document early institution of effective treatments. DESIGN Epidemiological and retrospective observational study. SETTING Representatives in states conducting SCID newborn screening were invited to submit their SCID screening algorithms, test performance data, and deidentified clinical and laboratory information regarding infants screened and cases with nonnormal results. Infants born from the start of each participating program from January 2008 through the most recent evaluable date prior to July 2013 were included. Representatives from 10 states plus the Navajo Area Indian Health Service contributed data from 3 030 083 newborns screened with a TREC test. MAIN OUTCOMES AND MEASURES Infants with SCID and other diagnoses of T-cell lymphopenia were classified. Incidence and, where possible, etiologies were determined. Interventions and survival were tracked. RESULTS Screening detected 52 cases of typical SCID, leaky SCID, and Omenn syndrome, affecting 1 in 58 000 infants (95%CI, 1/46 000-1/80 000). Survival of SCID-affected infants through their diagnosis and immune reconstitution was 87%(45/52), 92%(45/49) for infants who received transplantation, enzyme replacement, and/or gene therapy. Additional interventions for SCID and non-SCID T-cell lymphopenia included immunoglobulin infusions, preventive antibiotics, and avoidance of live vaccines. Variations in

The purpose of this study was to develop a simulation-based training program for people living with HIV (PLWH) as peer caregivers who would take care of terminally ill, HIV-infected patients. We used qualitative research methods and standardized patients to explore the meaning of caring for patients as peer caregivers. Study participants included 32 patients registered as PLWH at the South Korea Federation for HIV/AIDS. The meanings of peer caregiving were categorized into four dimensions: physical, psychological, relational, and economic. Our study had benefits in knowledge acquisition for caregivers as well as care recipients, empathy with HIV-infected care recipients, improvement in self-esteem and social participation, and financial self-sufficiency to enable independent living for caregivers. The simulation training program for PLWH peer caregivers for terminally ill HIV-infected patients demonstrated value, for both PLWH caregivers and terminally ill HIV-infected patients in South Korea, to improve the quality of care.

SUMMARY Involving low-income, ethnic minority families in lengthy HIV prevention programs can be challenging. Understanding the motivators and barriers to involvement may help researchers and practitioners design programs that can be used by populations most at risk for HIV exposure. The present study discusses motivators and barriers to involvement in the Collaborative HIV Prevention and Adolescent Mental Health Project (CHAMP), using data from a sample of 118 families that participated at varying levels in the twelve sessions of the program. Most participants chose motivators that reflect their perceptions of individual and/or family needs (“CHAMP might help me, mine, and other families”), and of characteristics of the program, such as CHAMP staff were friendly, CHAMP was fun. Among barriers to involvement, respondents expressed concerns about confidentiality, and about being judged by program staff. Respondents also reported experiencing many stressful events in their families (e.g., death and violence in the family) that may have been barriers to their involvement. Knowing these motivators and barriers, researchers and practitioners can enhance involvement in HIV prevention programs. PMID:20686648

Full Text Available Bolivian sex workers were more likely than other employed women to report tuberculosis screening only if they reported HIV screening. Of all women with household tuberculosis exposure, <40% reported screening for themselves or their children. Coupling tuberculosis screening with sex workers’ mandatory HIV screenings may be a cost-efficient disease-control strategy.

Knowing one's serostatus is critical in the HIV prevention, care and treatment continuum. This study examines the impact of communication programs on HIV testing in South Africa. Data came from 2204 young men and women aged 16-24 who reported to be sexually active in a population based survey. Structural equation modeling was used to test the directions and causal pathways between communication program exposure, HIV testing discussion, and having a test in the last 12 months. Bivariate and multivariate probit regressions provided evidence of exogeneity of communication exposure and the two HIV-related outcomes. One in three sampled individuals had been tested in the last 12 months. Communication program exposure only had an indirect effect on getting tested by encouraging young people to talk about testing. The study suggests that communication programs may create an environment that supports open HIV-related discussions and may have a long-term impact on behavior change.

Objective: From an actual cancer screening service demanders' perspective, we tried to understand the preference on screening frequency and willingness-to-pay for the packaging screening program on common cancers and to evaluate its long-term sustainability in urban populations in China. Methods: From 2012 to 2014, a multi-center cross-sectional survey was conducted among the actual screening participants from 13 provinces covered by the Cancer Screening Program in Urban China (CanSPUC). By face-to-face interview, information regarding to preference to screening frequency, willingness-to-pay for packaging screening program, maximum amount on payment and related reasons for unwillingness were investigated. Results: A total of 31 029 participants were included in this survey, with an average age as (55.2±7.5) years and median annual income per family as 25 000 Chinese Yuan. People's preference to screening frequency varied under different assumptions ( " totally free" and "self-paid" ). When the packaging screening was assumed totally free, 93.9% of residents would prefer to take the screening program every 1 to 3 years. However, the corresponding proportion dropped to 67.3% when assuming a self-paid pattern. 76.7% of the participants had the willingness-to-pay for the packaging screening, but only 11.2% of them would like to pay more than 500 Chinese Yuan (the expenditure of the particular packaging screening were about 1 500 Chinese Yuan). The remaining 23.3% of residents showed no willingness-to-pay, and the main reasons were unaffordable expenditure (71.7%) and feeling'no need'(40.4%). Conclusions: People who participated in the CanSPUC program generally tended to choose high-frequency packaging screening program, indicating the high potential acceptance for scale-up packaging screening, while it needs cautious assessments and rational guidance to the public. Although about seven in ten of the residents were willing to pay, the payment amount was limited

Structural HIV prevention interventions have gained prominence as ways to address underlying social and cultural factors that fuel the HIV epidemic. Identifying theories that explain how structural interventions are expected to change such factors can substantially increase their success. The Tchova Tchova community dialogue program, a theory-based intervention implemented in 2009-2010 in the provinces of Zambezia and Sofala, Mozambique, aimed to change gender and sexual norms for HIV prevention. Through facilitated sessions, the program sparked critical thinking and open dialogue among participants. This article measures the program's effectiveness based on a sample of 462 participants and 453 nonparticipants. The results show that the program was successful in producing changes in three of the underlying structural factors of HIV: gender attitudes, gender roles, and HIV stigma. The program was also successful in changing other factors associated with HIV infection, including HIV prevention knowledge, discussion of HIV between sex partners, and having multiple sex partners.

Full Text Available Human immunodeficiency virus causes the acquired immunodeficiency syndrome (AIDS and becomes a serious world-wide problem because of this disease's rapid propagation and incurability. Integrase strand transfer inhibitors (INSTIs supports HIV have rapid drug resistance for antitreatment. Screening the traditional Chinese medicine (TCM database by simulating molecular docking and molecular dynamics may select molecular compounds to inhibit INSTIs against HIV drug resistance. (S-cathinone and (1S,2S-norpseudoephedrine are selected based on structure and ligand-based drugs are designed and then get higher bioactivity predicted score from SVM than Raltegravir and other TCM compounds. The molecular dynamics are helpful in the analysis and detection of protein-ligand interactions. According to the docking poses, hydrophobic interactions and hydrogen bond variations define the main regions of important amino acids in integrase. In addition to the detection of TCM compound efficacy, we suggest (1S,2S-norpseudoephedrine is better than the others based on the analysis of interaction and the effect on the structural variation.

To determine the prevalence and behavioural correlates of HIV, HBV and HCV infections among Indonesian prisoners and to examine the impact of voluntary counselling and testing for all incoming prisoners on access to antiretroviral treatment (ART). In a non-anonymous survey in an Indonesian prison for drug-related offences, all incoming prisoners and symptomatic resident prisoners were counselled and offered testing for HIV, hepatitis B and C. Screening was performed in 679 incoming prisoners, of whom 639 (94.1%) agreed to be tested, revealing a seroprevalence of 7.2% (95% CI 5.2-9.2) for HIV, 5.8% (95% CI 3.9-7.6) for HBsAg and 18.6% (95% CI 15.5-21.6) for HCV. Of 57 resident prisoners tested, 29.8% were HIV-positive. HIV infection was strongly associated with injecting drug use (IDU; P prisoners was responsible for diagnosing and treating HIV in 73.0%, respectively, and 68.0% of HIV-positive individuals. HIV and HCV are highly prevalent among incoming Indonesian prisoners and almost entirely explained by IDU.

Based on analysis of data collected from the national tuberculosis prevention program in Djibouti between 1990 and 1996, the authors analyzed the relationship between HIV infection and tuberculosis. The study cohort comprised a total of 22,000 patients including 14,000 with documented HIV infection. Although HIV infection probably worsened the situation, it was neither the only nor the main factor involved in the resurgence of tuberculosis. Demographic growth, higher population density, and increasing poverty as well as the quality of the national tuberculosis prevention program must be taken into account. The incidence of smear-negative tuberculosis was not significantly higher in HIV-infected patients (incidence of smear positive cases, > 92%). Extrapulmonary tuberculosis especially of pleural involvement was more common (15% versus 9.4%). Treatment was effective in HIV-infected patients. If directly observed (DOT) therapy was used, there was no risk of emergence of multidrug-resistant tuberculosis strains. Drug side-effects associated with the protocols used in Djibouti were not greater in HIV-infected patients. Most additional mortality observed in HIV-infected tuberculosis patients (10.5% versus 2%) was due to progression of HIV infection.

Community-based care (CBC) can increase access to key services for people affected by HIV/AIDS through the mobilization of community interests and resources and their integration with formal health structures. Yet, the lack of a systematic framework for analysis of CBC focused on HIV/AIDS impedes our ability to understand and study CBC programs. We sought to develop taxonomy of CBC programs focused on HIV/AIDS in resource-limited settings in an effort to understand their key characteristics, uncover any gaps in programming, and highlight the potential roles they play. Our review aimed to systematically identify key CBC programs focused on HIV/AIDS in resource-limited settings. We used both bibliographic database searches (Medline, CINAHL, and EMBASE) for peer-reviewed literature and internet-based searches for gray literature. Our search terms were 'HIV' or 'AIDS' and 'community-based care' or 'CBC'. Two co-authors developed a descriptive taxonomy through an iterative, inductive process using the retrieved program information. We identified 21 CBC programs useful for developing taxonomy. Extensive variation was observed within each of the nine categories identified: region, vision, characteristics of target populations, program scope, program operations, funding models, human resources, sustainability, and monitoring and evaluation strategies. While additional research may still be needed to identify the conditions that lead to overall program success, our findings can help to inform our understanding of the various aspects of CBC programs and inform potential logic models for CBC programming in the context of HIV/AIDS in resource-limited settings. Importantly, the findings of the present study can be used to develop sustainable HIV/AIDS-service delivery programs in regions with health resource shortages.

Full Text Available The Southern states experience the highest rates of HIV and AIDS in the US, and point-of-care (POC testing outside of primary care may contribute to status awareness in medically underserved populations in this region. To evaluate POC screening and linkage to care at an urban south site, analyses were performed on a dataset of 3,651 individuals from an integrated rapid-result HIV testing and linkage program to describe this test-seeking cohort and determine trends associated with screening, results, and linkage to care. Four percent of the population had positive results. We observed significant differences by test result for age, race and gender, reported risk behaviors, test location, and motivation for screening. The overall linkage rate was 86%, and we found significant differences for clients who were linked to HIV care versus persons whose linkage could not be confirmed with respect to race and gender, location, and motivation. The linkage rate for POC testing that included a comprehensive intake visit and colocated primary care services for in-state residents was 97%. Additional research on integrated POC screening and linkage methodologies that provide intake services at time of testing is essential for increasing status awareness and improving linkage to HIV care in the US.

Opportunity Knocks: HIV Prevention in Primary Care.

Thrun, Mark W

2014-06-01

Expansions in health care coverage, a comprehensive framework for HIV prevention and care, electronic medical records, and novel HIV prevention modalities create a current opportunity to change the trajectory of the HIV epidemic in the United States. HIV is increasingly disproportionately found in populations historically at higher risk, including gay men and other men who have sex with men, transgender women, injection drug users, and persons of color. This underscores the need for providers to identify persons at higher risk for HIV and assure the provision of screening and prevention services. In turn, universal screening for HIV-testing every adolescent and adult at least once in their lifetime-will increasingly be necessary to find the infrequent cases of HIV in lower risk populations. In both these domains, primary care providers will play a unique role in complementing traditional providers of HIV prevention and care services by increasing the proportion of their patients who have been screened for HIV, opening dialogues around sexual health, including asking about sexual orientation and gender identity, and prescribing antivirals as pre- and postexposure prophylaxis for their non-HIV-infected patients. Primary care providers must understand and embrace their importance along the HIV prevention and care continuum.

Using a community-based, socialist feminist qualitative study, and an emergent research design, we explored the unique individual experiences of South Asian immigrant women living with HIV in the Greater Toronto Area (GTA) of Ontario, Canada. We assessed both the HIV risk context and the strategies for HIV education and prevention as expressed by study participants. Grounded in Connell's social theory of gender, a thematic analysis of semi-structured interviews with 12 women yielded six themes related to the power and impact of stigmatization, community's denial of HIV, infidelity, manifested in resistance to discussing sex and condom use, non-disclosure, and lack of HIV knowledge. This study validated the legitimacy of listening to the voices of South Asian immigrant women living with HIV, who communicated 20 recommendations for researchers, educators, community organizations, and service providers to culturally-tailor HIV education programs.

We assessed the usefulness of the National TB and Leprosy Control Program (NTLP) symptom-based tuberculosis (TB) screening tool in identifying HIV-infected patients eligible for isoniazid preventive therapy in Muhimbili National Hospital, Dar es Salaam Tanzania. Descriptive cross-sectional study. Data collected included socio-demographic and clinical data. Chest X-ray, sputum for acid-fast bacilli (AFB) microscopy, mycobacterial culture, CD4 + count and complete blood count were performed. Patients were considered not having active TB if they presented with no symptom in the screening tool, which comprised these symptoms: cough, fever and excessive night sweats for ≥2 weeks; weight loss of ≥3 kg in 4 weeks and haemoptysis of any duration. The reference standard was a negative culture for Mycobacterium tuberculosis. We enroled 373 patients, of whom 72.1% were females. Active pulmonary TB was found in 4.1% (14/338) of the participants as defined by a positive culture. The sensitivity and specificity of the NTLP screening tool were 71.4% (10/14) and 75.9% (246/324), respectively. False-negative rate was 28.6% (4/10). Cough, fever for ≥2 weeks and weight loss were independent predictors of NTLP-defined TB. Cough ≥2 weeks predicted TB when a positive culture was used to define TB. The screening tool had fairly good sensitivity and specificity for TB screening; however, there is a possibility that about 29% of the screened population will be given IPT while they are supposed to receive a full course of TB treatment. © 2014 John Wiley & Sons Ltd.

The Manitoba Perinatal Screening Program is guided by a committee of medical specialists with skills in the diagnosis and management of disorders of metabolism in the newborn. The program is voluntary and is centralized at Cadham Provincial Laboratory, in Winnipeg. A filter card blood specimen is collected from newborns on discharge from hospital, and a filter card urine sample is collected and mailed to the laboratory by the mother when the infant is about 2 weeks of age. The overall compliance rates for the blood and urine specimens are approximately 100% and 84% respectively. The blood specimen is screened for phenylalanine and other amino acids, thyroxine, galactose, galactose-1-phosphate and biotinidase. The urine specimen is screened for amino acids, including cystine, as well as methylmalonic acid and homocystine. Between 1965 and 1985, 83 cases of metabolic disorders were detected, including 23 cases of primary hypothyroidism, 14 of classic phenylketonuria, 5 of galactosemia variants, 3 of galactosemia, 2 of maple syrup urine disease and 1 of hereditary tyrosinemia. The direct cost per infant screened is $5.50, and the cost:benefit ratio is approximately 7.5:1. Maternal serum alpha-fetoprotein screening is being made available as the necessary supporting clinical facilities become available. On the basis of this experience, the author outlines the components that are important for an effective screening program. PMID:3676929

Full Text Available Objective: HIV infection is a sensitive issue in black communities [Serrant-Green L. Black Caribbean men, sexual health decisions and silences. Doctoral thesis. Nottingham School of Nursing, University of Nottingham; 2004]. Statistics show black sub-Saharan African (BSSA communities disproportionately constitute two-thirds of people with HIV [Heath Protection Agency. Health protection report: latest infection reports-GOV.UK; 2013]. African communities constitute 30% of people accessing HIV treatment in the United Kingdom yet represent less than 1% of the population [Health Protection Agency. HIV in the United Kingdom: 2012 report; 2012], [Department of Health. DVD about FGM. 2012. Available from fgm@dh.gsi.gov.uk.]. This article explores the sociocultural challenges in engaging BSSA communities in HIV prevention programs in England and possible strategies to improve their involvement. Methods: Twelve focus group discussions and 24 semistructured interviews were conducted in a 2-year period with participants from the BSSA communities and sexual health services in the West Midlands, England. The research was supported by the Ubuntu scheme, a sexual health initiative working with African communities in Birmingham, England. Results: Ineffective engagement with African communities can hinder the effectiveness of HIV prevention programs. Skills and strategies sensitive to BSSA culture are important for successful implementation of prevention programs. HIV prevention programs face challenges including stigma, denial, and marginalized views within BSSA communities. Conclusion: Networking, coordination, and cultural sensitivity training for health professionals are key strategies for engaging BSSA communities in HIV prevention programs.

African Americans and Hispanics are disproportionately affected by the HIV/AIDS epidemic. Within the most heavily affected cities, a few neighborhoods account for a large share of new HIV infections. Addressing racial and economic disparities in HIV infection requires an implementation program and research agenda that assess the impact of HIV prevention interventions focused on increasing HIV testing, treatment, and retention in care in the most heavily affected neighborhoods in urban areas of the United States. Neighborhood-based implementation research should evaluate programs that focus on community mobilization, media campaigns, routine testing, linkage to and retention in care, and block-by-block outreach strategies.

Full Text Available Community health worker (CHW programs are believed to be poorly coordinated, poorly integrated into national health systems, and lacking long-term support. Duplication of services, fragmentation, and resource limitations may have impeded the potential impact of CHWs for achieving HIV goals. This study assesses mediators of a more harmonized approach to implementing large-scale CHW programs for HIV in the context of complex health systems and multiple donors.We undertook four country case studies in Lesotho, Mozambique, South Africa, and Swaziland between August 2015 and May 2016. We conducted 60 semistructured interviews with donors, government officials, and expert observers involved in CHW programs delivering HIV services. Interviews were triangulated with published literature, country reports, national health plans, and policies. Data were analyzed based on 3 priority areas of harmonization (coordination, integration, and sustainability and 5 components of a conceptual framework (the health issue, intervention, stakeholders, health system, and context to assess facilitators and barriers to harmonization of CHW programs. CHWs supporting HIV programs were found to be highly fragmented and poorly integrated into national health systems. Stakeholders generally supported increasing harmonization, although they recognized several challenges and disadvantages to harmonization. Key facilitators to harmonization included (i a large existing national CHW program and recognition of nongovernmental CHW programs, (ii use of common incentives and training processes for CHWs, (iii existence of an organizational structure dedicated to community health initiatives, and (iv involvement of community leaders in decision-making. Key barriers included a wide range of stakeholders and lack of ownership and accountability of non-governmental CHW programs. Limitations of our study include subjectively selected case studies, our focus on decision-makers, and limited

Full Text Available Purpose. To describe integration of fundus autofluorescence (FAF imaging into an ocular screening program. Methods. Fifty consecutive screening participants were included in this prospective pilot imaging study. Color and FAF (530/640 nm exciter/barrier filters images were obtained with a 15.1MP Canon nonmydriatic hybrid camera. A clinician evaluated the images on site to determine need for referral. Visual acuity (VA, intraocular pressure (IOP, and ocular pathology detected by color fundus and FAF imaging modalities were recorded. Results. Mean ± SD age was 47.4 ± 17.3 years. Fifty-two percent were female and 58% African American. Twenty-seven percent had a comprehensive ocular examination within the past year. Mean VA was 20/39 in the right eye and 20/40 in the left eye. Mean IOP was 15 mmHg bilaterally. Positive color and/or FAF findings were identified in nine (18% individuals with diabetic retinopathy or macular edema (n=4, focal RPE defects (n=2, age-related macular degeneration (n=1, central serous retinopathy (n=1, and ocular trauma (n=1. Conclusions. FAF was successfully integrated in our ocular screening program and aided in the identification of ocular pathology. Larger studies examining the utility of this technology in screening programs may be warranted.

2013-09-01

In this review, we explore current questions regarding risk factors contributing to frequent and early onset of lung cancer among populations with HIV infection, treatment, and outcomes of lung cancer in HIV-infected patients as well as challenges in a newly evolving era of lung cancer screening. Lung cancer, seen in three-fold excess in HIV-infected populations, has become the most common non-AIDS defining malignancy in the highly active antiretroviral therapy era. HIV-associated lung cancer appears to be associated with young age at diagnosis, cigarette smoking, advanced stage at presentation, and a more aggressive clinical course. There is no unified explanation for these observations, and aside from traditional risk factors, HIV-related immunosuppression and biological differences might play a role. In addition to smoking cessation interventions, screening and early cancer detection in HIV-infected populations are of high clinical importance, although evidence supporting lung cancer screening in this particularly high-risk subset is currently lacking, as are prospective studies of lung cancer therapy. There is an urgent need for prospective clinical trials in HIV-associated lung cancer to improve understanding of lung cancer pathogenesis and to optimize patient care. Several clinical trials are in progress to address questions in cancer biology, screening, and treatment for this significant cause of mortality in persons with HIV infection.

HIV and Pregnancy in Resource-Poor Settings

There are 33.4 million people living with human immunodeficiency virus (HIV) or acquired immunodeficiency syndrome. Globally, HIV/AIDS is the leading cause of death among women of reproductive age. In the United States and other developed countries, aggressive efforts to treat HIV-positive pregnant women with highly active antiretroviral therapy have decreased the maternal-to-child transmission (MTCT) from over 20% to less than 2%. However, in resource-poor settings, access to antiretroviral therapy (ART) is not readily available, and perinatal transmission rates remain as high as 45%. Women are at greater risk of heterosexual transmission of HIV, which is compounded by lack of condom use, imbalance of social power, and the high fertility rate. Prevention programs are needed to empower and educate women and engender community awareness for condom use. Prenatal screening and treatment, intrapartum ART, and postpartum prophylaxis must be made available to all women and children to prevent MTCT. PMID:20842284

In the field of human immunodeficiency virus (HIV) prevention, there has been increasing interest in the role that gender plays in HIV and violence risk, and in successfully engaging men in the response. This article highlights findings from more than 10 studies in Asia, Africa, and Latin America--conducted from 1997 through 2007 as part of the Horizons program--that have contributed to understanding the relationship between gender and men's behaviors, developing useful measurement tools for gender norms, and designing and evaluating the impact of gender-focused program strategies. Studies showed significant associations between support for inequitable norms and risk, such as more partner violence and less condom use. Programmatic lessons learned ranged from insights into appropriate media messages, to strategies to engage men in critically reflecting upon gender inequality, to the qualities of successful program facilitators. The portfolio of work reveals the potential and importance of directly addressing gender dynamics in HIV- and violence-prevention programs for both men and women.

The aim of this work was quality assessment of HIV diagnostic procedures in Poland, including human and technical resources as well as laboratory practice. Sixty questionnaires were distributed among diagnostic centers to obtain qualitative data. Basing on the survey data serological control using coded panels of HIV-1/2 samples was performed. Thirty-one filled questionnaires were received (50.8%). Surveyed laboratories perform from 350 to 5500 serological screening tests per year. In most of laboratories fourth generation assays are available, while Blood Donation Centers screen the blood both with serological assays and by HIV-RNA detection. Sanitary and Epidemiological Stations and academic laboratories hold the ISO/IEC 17025 or IS0 9001:2001 accreditation, five of the surveyed centers participate in Labquality assurance and two in Quality Control in Molecular Diagnostics programs. Data of control serological testing were received from 21 centers. In the quality control assessment 194 analyses were performed with 91 true negative, 2 false negative, 96 true positive and 5 false positive results. False negative rate of % and false positive rate of 5.2% was noted for this study. Currently, virtually no guidelines related to the HIV-diagnostics quality assurance and control in Poland are in delineated. Development of the national unified quality control system, basing on the central institution is highly desirable. National certification within the frames of the quality control and assurance program should be mandatory for all the diagnostic labs, and aim at improvement of reliability of the result distributed among clinicians and patients.

Full Text Available Abstract Background Neonatal hearing screening (NHS has been routinely offered as a vital component of early childhood care in developed countries, whereas such a screening program is still at the pilot or preliminary stage as regards its nationwide implementation in developing countries. To provide significant evidence for health policy making in China, this study aims to determine the cost-effectiveness of NHS program implementation in case of eight provinces of China. Methods A cost-effectiveness model was conducted and all neonates annually born from 2007 to 2009 in eight provinces of China were simulated in this model. The model parameters were estimated from the established databases in the general hospitals or maternal and child health hospitals of these eight provinces, supplemented from the published literature. The model estimated changes in program implementation costs, disability-adjusted life years (DALYs, average cost-effectiveness ratio (ACER, and incremental cost-effectiveness ratio (ICER for universal screening compared to targeted screening in eight provinces. Results and discussion A multivariate sensitivity analysis was performed to determine uncertainty in health effect estimates and cost-effectiveness ratios using a probabilistic modeling technique. Targeted strategy trended to be cost-effective in Guangxi, Jiangxi, Henan, Guangdong, Zhejiang, Hebei, Shandong, and Beijing from the level of 9%, 9%, 8%, 4%, 3%, 7%, 5%, and 2%, respectively; while universal strategy trended to be cost-effective in those provinces from the level of 70%, 70%, 48%, 10%, 8%, 28%, 15%, 4%, respectively. This study showed although there was a huge disparity in the implementation of the NHS program in the surveyed provinces, both universal strategy and targeted strategy showed cost-effectiveness in those relatively developed provinces, while neither of the screening strategy showed cost-effectiveness in those relatively developing provinces.

Bolivian sex workers were more likely than other employed women to report tuberculosis screening only if they reported HIV screening. Of all women with household tuberculosis exposure, <40% reported screening for themselves or their children. Coupling tuberculosis screening with sex workers' mandatory HIV screenings may be a cost-efficient disease-control strategy. Copyright © 2014 Ministry of Health, Saudi Arabia.

Background: A population-based program promoting the Fecal Occult Blood Test (FOBT) for colorectal cancer screening was introduced in 2008 in Ontario, Canada, where opportunistic screening with colonoscopy had been increasing in frequency. We evaluated the impact of the program on income and immigration-related disparities in screening. Methods: We used linked administrative data to calculate colorectal cancer screening rates for eligible Ontarians in each year between 2001/02 ( n = 2,852,619) and 2013/14 ( n = 4,139,304). We quantified disparities using an "inequality ratio" of screening rates in the most disadvantaged group relative to the most advantaged group. We performed segmented logistic regression analyses stratified by screening modality and adjusted for age, sex, rurality, comorbidity, and morbidity. Results: Between 2001/02 and 2013/14, the income and immigration inequality ratios narrowed from 0.74 to 0.80 and 0.55 to 0.69, respectively. Before the screening program, the income inequality ratio was widening by 1% per year (95% CI 1% to 1%); in the year it was introduced, it narrowed by 4% (95% CI 2% to 7%) and in the years following, it remained stable [0% decrease (95% CI 1% decrease to 0% decrease) per year]. Results were similar for immigration-related disparities. After program introduction, disparities in receiving FOBT were narrowing at a faster rate while disparities in receiving colonoscopy were widening at a slower rate. Conclusions: Introduction of a population-based screening program promoting FOBT for colorectal cancer was associated with only modest improvements in immigration and income-related disparities. Impact: Reducing immigration and income-related disparities should be a focus for future research and policy work. Disparities in Ontario seem to be driven by a higher uptake of colonoscopy among more advantaged groups.

The recent approval of 4th generation HIV tests has forced many laboratories to decide whether to shift from 3rd to these tests. There are limited published studies on the comparative evaluation of these two different assays. We compare the performance of fourth-generation electrochemiluminescence immunoassay (ChIA) and third-generation enzyme linked immunosorbent assay (EIA) for human immunodeficiency virus (HIV) screening and gauge whether the shift from EIA to ChIA could be better in a multiethnic region of China. We identified a large number of routine specimens (345,492) using two different assays from Jan 2008 to Aug 2011 in a teaching hospital with high sample throughput. Of the 344,596 specimens with interpretable HIV test results, 526(0.23%) of 228,761 using EIA and 303(0.26%) of 115,835 using ChIA were HIV-1 positive. The false-positive rate of EIA was lower than that of ChIA [0.03% vs. 0.08%, odds ratio 0.33 (95% confidence interval 0.24, 0.45)]. The positive predictive value (PPV) of EIA (89.6%) was significantly higher than that of ChIA (76.1%) (<0.001), reflecting the difference between the two assays. The clinical sensitivities of two assays in this study were 99.64% for EIA and 99.88% for ChIA. Caution is needed before shifting from 3rd to 4th generation HIV tests. Since none of these tests are perfect, different geographic and ethnic area probably require different considerations with regard to HIV testing methods, taking into account the local conditions.

Psychological and social problems are major concerns in this era of successful antiretroviral therapy. Although livelihood programs have been implemented extensively to improve the daily living conditions of people living with HIV in Cambodia, no studies have yet investigated the impacts of these programs on the mental health of this vulnerable population. Therefore, we examined the impact of a livelihood program on depressive symptoms and associated factors among people living with HIV in Cambodia. A quasi-experimental, nonequivalent comparison group study was conducted in six provinces of Cambodia in 2014. Data were collected from an intervention group comprising 357 people living with HIV who had participated in the livelihood program and a comparison group comprising 328 people living with HIV who had not participated in this program. Multiple logistic regression analysis was carried out to examine the association between livelihood-program participation and depressive symptoms as measured by the depressive symptoms subscale of the 25-item Cambodian version of the Hopkins Symptom Checklist. A propensity score matching was used to examine the effect of the livelihood program on depressive symptoms while controlling for selection bias. Overall, 56.0% and 62.7% of the participants in the intervention and comparison groups, respectively, met the Hopkins Symptom Checklist threshold for depressive symptoms. The multiple logistic regression analysis showed that the participants in the intervention group had significantly lower odds of having depressive symptoms (adjusted odds ratio 0.68, 95% confidence interval 0.52-0.88). The analysis from propensity score matching indicated that the livelihood program helped mitigate depressive symptoms among the participants in the intervention group (T=-1.99). The livelihood program appeared to help mitigate the burden of depressive symptoms among people living with HIV in Cambodia. Thus, this program should be scaled up and

To investigate the probability of breast cancer among women recalled due to abnormal findings on the screening mammograms (PPV-1) and among women who underwent an invasive procedure (PPV-2) by mammographic density (MD), screening mode and age. We used information about 28,826 recall examinations from 26,951 subsequently screened women in the Norwegian Breast Cancer Screening Program, 1996-2010. The radiologists who performed the recall examinations subjectively classified MD on the mammograms into three categories: fatty (70%). Screening mode was defined as screen-film mammography (SFM) and full-field digital mammography (FFDM). We examined trends of PPVs by MD, screening mode and age. We used logistic regression to estimate odds ratio (OR) of screen-detected breast cancer associated with MD among women recalled, adjusting for screening mode and age. PPV-1 and PPV-2 decreased by increasing MD, regardless of screening mode (p for trend breasts. Among women recalled, the adjusted OR of breast cancer decreased with increasing MD. Compared with women with fatty breasts, the OR was 0.90 (95% CI: 0.84-0.96) for those with medium dense breasts and 0.85 (95% CI: 0.76-0.95) for those with dense breasts. PPVs decreased by increasing MD. Fewer women needed to be recalled or undergo an invasive procedure to detect one breast cancer among those with fatty versus dense breasts in the screening program in Norway, 1996-2010.

Full Text Available Abstract Background Cancer of the cervix is the second commonest malignancy in females worldwide and is the leading malignancy among women in Tanzania. Cancer of the cervix has been strongly associated with Human Papilloma Virus (HPV which is a sexually transmitted disease. However, the role of HIV-1 in the aetiology of cancer of the cervix is less clear. Studies suggest that HPV and HIV-1 infection are synergistic and therefore their dual occurrence may fuel increased incidence of cancer of the cervix and AIDS. We therefore conducted a study to determine the association between cancer of the cervix and HIV-1. Methods The study was carried out in Ocean Road Cancer Institute, Dar-es-salaam, Tanzania between January and March 2007. A hospital-based case control design was used to study 138 cases and 138 controls. The cases were consenting women 18 years and above with histologically confirmed squamous cell carcinoma of the cervix, while the controls were consenting non-cancer adult women attendants or visitors. The participants were counselled and tested for HIV-1 and interviewed to assess risk factors for cancer of the cervix and HIV-1. Estimation of risk was done by computing odds ratios and confidence intervals. Confounding and interaction between the factors were assessed using logistic regression. Results HIV-1 prevalence was much higher among the cases (21.0% than among the controls (11.6%. In logistic regression, HIV-1 was associated with cancer of the cervix (OR = 2.9, 95% CI = 1.4–5.9. Among the cases the mean age was lower for HIV-1 infected (44.3 years than HIV-1 uninfected women (54 years, p = 0.0001. Conclusion HIV-1 infection is associated with invasive cancer of the cervix. Resource-constrained countries with a high burden of HIV-1 and cervical cancer should adopt a high-risk approach that targets HIV-1 positive women for screening of cervical cancer initially by utilizing HIV/AIDS resources.

Stigmatization of carrier status: social implications of heterozygote genetic screening programs.

Kenen, R H; Schmidt, R M

1978-01-01

Possible latent psychological and social consequences ensuing from genetic screening programs need to be investigated during the planning phase of national genetic screening programs. The relatively few studies which have been performed to determine psychological, social, and economic consequences resulting from a genetic screening program are reviewed. Stigmatization of carrier-status, having major psychosocial implications in heterozygote genetic screening programs, is discussed and related to Erving Goffman's work in the area of stigmatization. Questions are raised regarding the relationship between such variables as religiosity and sex of the individual and acceptance of the status of newly identified carrier of a mutant gene. Severity of the deleterious gene and visibility of the carrier status are two important factors to consider in an estimation of potential stigma. Specific implications are discussed for four genetic diseases: Tay-Sachs, Sickle-Cell Anemia, Huntington's disease and Hemophilia. PMID:152585

HIV point-of-care testing (POCT) was approved for use in Canada in 2005 and provides important public health benefits by providing rapid screening results rather than sending a blood sample to a laboratory and waiting on test results. Access to test results soon after testing (or during the same visit) is believed to increase the likelihood that individuals will receive their results and improve access to confirmatory testing and linkages to care. This paper reviews the literature on the utilization of HIV POCT across Canadian provinces. We searched OVID Medline, Embase, EBM Reviews, PsycINFO, CINAHL, and 20 electronic grey literature databases. All empirical studies investigating HIV POCT programs in Canada published in French or English were included. Searches of academic databases identified a total of 6,091 records. After removing duplicates and screening for eligibility, 27 records were included. Ten studies are peer-reviewed articles, and 17 are grey literature reports. HIV POCT in Canada is both feasible and accepted by Canadians. It is preferred to conventional HIV testing (ranging from 81.1 to 97%), and users are highly satisfied with the testing process (ranging between 96 and 100%). The majority of studies demonstrate that HIV POCT is feasible, preferred, and accepted by diverse populations in Canada. Losses to follow-up and linkage rates are also good. However, more research is needed to understand how best to scale up HIV POCT in contexts that currently have very limited or no access to testing.

Full Text Available People who inject drugs are at risk of various infectious diseases. Despite such a risk, evidence is limited which studied the utilization of screening services for common infectious diseases among people who inject drugs in Tanzania. We aimed to examine their high-risk behaviors; utilization of screening services for HIV infection, hepatitis B/C, any other sexually transmitted infection, and tuberculosis; and their associated factors in Dar es Salaam, Tanzania.We conducted a baseline cross-sectional study as part of a prospective cohort study of people who inject drugs. We included 578 participants comprising of new enrollees of the integrated methadone-assisted treatment program and those who were selected from the communities but not enrolled in the program. We interviewed new enrollees preceding their enrollment and receipt of services from the program. We measured participants' high-risk behaviors and their utilization of screening services. We analyzed the data descriptively and used multiple logistic regressions to identify the factors associated with ever being screened for infectious diseases.Of 578 participants, 14.2% shared injection needles. Of 547 sexually active participants, 37.5% had multiple sexual partners and only 17.4% used a condom. Of all participants, however, only 36.0% had ever been screened for HIV infection, 18.5% for tuberculosis, 11.8% for any other sexually transmitted infection, and 11.6% for hepatitis B/C. They were more likely to have ever been screened for HIV infection if they had education levels above primary education (adjusted odds ratio [AOR]: 2.54, 95% CI: 1.54-4.20, had a history of transactional sex (OR: 2.63, 95% CI: 1.01-6.84, and were new enrollees of the program (AOR: 7.41, 95% CI: 4.41-12.86.People who inject drugs practice high-risk behaviors but their utilization of screening services for infectious diseases is poor in Dar es Salaam, Tanzania.

Cervical cancer is a major public health problem in resource-limited settings, particularly among HIV-infected women. Given the challenges of cytology-based approaches, the efficiency of new screening programs need to be assessed. Community and hospital-based clinics in Gaborone, Botswana. To determine the feasibility and efficiency of the "see and treat" approach using visual inspection acetic acid (VIA) and enhanced digital imaging (EDI) for cervical cancer prevention in HIV-infected women. A 2-tier community-based cervical cancer prevention program was implemented. HIV-infected women were screened by nurses at the community using the VIA/EDI approach. Low-grade lesions were treated with cryotherapy on the same visit. Women with complex lesions were referred to our second tier specialized clinic for evaluation. Weekly quality control assessments were performed by a specialist in collaboration with the nurses on all pictures taken. From March 2009 through January 2011, 2175 patients were screened for cervical cancer at our community-based clinic. Two hundred fifty-three patients (11.6%) were found to have low-grade lesions and received same-day cryotherapy. One thousand three hundred forty-seven (61.9%) women were considered to have a normal examination, and 575 (27.3%) were referred for further evaluation and treatment. Of the 1347 women initially considered to have normal exams, 267 (19.8%) were recalled based on weekly quality control assessments. Two hundred ten (78.6%) of the 267 recalled women, and 499 (86.8%) of the 575 referred women were seen at the referral clinic. Of these 709 women, 506 (71.4%) required additional treatment. Overall, 264 cervical intraepithelial neoplasia stage 2 or 3 were identified and treated, and 6 microinvasive cancers identified were referred for further management. Our "see and treat" cervical cancer prevention program using the VIA/EDI approach is a feasible, high-output and high-efficiency program, worthy of considering as an

Routine linked HIV antenatal screening, with "opt-out", was introduced at the Rotunda in January 1998. This paper reviews the screening and subsequent pregnancy management and outcome in HIV positive women from 1998 to 2006. During this time 225 women (280 pregnancies) were HIV positive and 194 women subsequently delivered at the Rotunda, representing 233 liveborn infants. Overall anti-HIV prevalence was 0.42%, increasing from 0.06% in 1998 to 0.57% in 2006. Of 233 livebirths, 111 (48%) were delivered by spontaneous vaginal delivery (SVD). HIV treatment was started pre-pregnancy in 14 (6%) pregnancies and antenatally in 208 (90%). The vertical transmission rate in mothers receiving >4 weeks of treatment was 0%. We conclude that routine antenatal HIV screening is effective and significantly benefits the health of mother and child.

This paper reviews the screening and subsequent pregnancy management and outcome in HIV positive women from 1998 to 2006. During this time 225 women (280 pregnancies) were HIV positive and 194 women subsequently delivered at the Rotunda, representing 233 liveborn infants. Overall anti-HIV prevalence was 0.42%, increasing from 0.06% in 1998 to 0.57% in 2006. Of 233 livebirths, 111 (48%) were delivered by spontaneous vaginal delivery (SVD). HIV treatment was started pre-pregnancy in 14 (6%) pregnancies and antenatally in 208 (90%). The vertical transmission rate in mothers receiving >4 weeks of treatment was 0%. We conclude that routine antenatal HIV screening is effective and significantly benefits the health of mother and child.

Abstract Objective To improve the Zambia Prisons Service’s implementation of tuberculosis screening and human immunodeficiency virus (HIV) testing. Methods For both tuberculosis and HIV, we implemented mass screening of inmates and community-based screening of those residing in encampments adjacent to prisons. We also established routine systems – with inmates as peer educators – for the screening of newly entered or symptomatic inmates. We improved infection control measures, increased diagnostic capacity and promoted awareness of tuberculosis in Zambia’s prisons. Findings In a period of 9 months, we screened 7638 individuals and diagnosed 409 new patients with tuberculosis. We tested 4879 individuals for HIV and diagnosed 564 cases of infection. An additional 625 individuals had previously been found to be HIV-positive. Including those already on tuberculosis treatment at the time of screening, the prevalence of tuberculosis recorded in the prisons and adjacent encampments – 6.4% (6428/100 000) – is 18 times the national prevalence estimate of 0.35%. Overall, 22.9% of the inmates and 13.8% of the encampment residents were HIV-positive. Conclusion Both tuberculosis and HIV infection are common within Zambian prisons. We enhanced tuberculosis screening and improved the detection of tuberculosis and HIV in this setting. Our observations should be useful in the development of prison-based programmes for tuberculosis and HIV elsewhere. PMID:25883402

South Africa has high rates of HIV and HPV and high incidence and mortality from cervical cancer. However, cervical cancer is largely preventable when early screening and treatment are available. We estimate the costs and cost-effectiveness of conventional cytology (Pap), visual inspection with acetic acid (VIA) and HPV DNA testing for detecting cases of CIN2+ among HIV-infected women currently taking antiretroviral treatment at a public HIV clinic in Johannesburg, South Africa. Method effectiveness was derived from a validation study completed at the clinic. Costs were estimated from the provider perspective using micro-costing between June 2013-April 2014. Capital costs were annualized using a discount rate of 3%. Two different service volume scenarios were considered. Threshold analysis was used to explore the potential for reducing the cost of HPV DNA testing. VIA was least costly in both scenarios. In the higher volume scenario, the average cost per procedure was US$ 3.67 for VIA, US$ 8.17 for Pap and US$ 54.34 for HPV DNA. Colposcopic biopsies cost on average US$ 67.71 per procedure. VIA was least sensitive but most cost-effective at US$ 17.05 per true CIN2+ case detected. The cost per case detected for Pap testing was US$ 130.63 using a conventional definition for positive results and US$ 187.52 using a more conservative definition. HPV DNA testing was US$ 320.09 per case detected. Colposcopic biopsy costs largely drove the total and per case costs. A 71% reduction in HPV DNA screening costs would make it competitive with the conservative Pap definition. Women need access to services which meet their needs and address the burden of cervical dysplasia and cancer in this region. Although most cost-effective, VIA may require more frequent screening due to low sensitivity, an important consideration for an HIV-positive population with increased risk for disease progression.

In the United States, Lung Cancer is responsible for more cancer deaths than the next four cancers combined. In addition, the 5 year survival rate for lung cancer patients has not improved over the past 40 to 50 years. To combat this deadly disease, in 2002 the National Cancer Institute launched a very large Randomized Control Trial called the National Lung Screening Trial (NLST). This trial would randomize subjects who had substantial risk of lung cancer (due to age and smoking history) into either a Chest X-ray arm or a low dose CT arm. In November 2010, the National Cancer Institute announced that the NLST had demonstrated 20% fewer lung cancer deaths among those who were screened with low-dose CT than with chest X-ray. In December 2013, the US Preventive Services Task Force recommended the use of Lung Cancer Screening using low dose CT and a little over a year later (Feb. 2015), CMS announced that Medicare would also cover Lung Cancer Screening using low dose CT. Thus private and public insurers are required to provide Lung Cancer Screening programs using CT to the appropriate population(s). The purpose of this Symposium is to inform medical physicists and prepare them to support the implementation of Lung Screening programs. This Symposium will focus on the clinical aspects of lung cancer screening, requirements of a screening registry for systematically capturing and tracking screening patients and results (such as required Medicare data elements) as well as the role of the medical physicist in screening programs, including the development of low dose CT screening protocols. Learning Objectives: To understand the clinical basis and clinical components of a lung cancer screening program, including eligibility criteria and other requirements. To understand the data collection requirements, workflow, and informatics infrastructure needed to support the tracking and reporting components of a screening program. To understand the role of the medical physicist in

HIV screening assays have gone through several generations of development in an effort to narrow the "window period" of detection. Utilizing a fourth generation HIV screening assay has the potential to detect earlier HIV infection, thus reducing HIV-1 transmission. To identify acute infections to decrease HIV transmission in San Diego County. Serum specimens were collected from clients seen by multiple submitters in San Diego County. All acceptable specimens were screened using the 4th Gen Combo Assay. Initially reactive specimens were repeated in duplicate and if repeatedly reactive, were confirmed by HIV-1 Immunofluorescent Antibody Assay (IFA). IFA negative/inconclusive specimens were sent for HIV-1 NAT and HIV-2 antibody testing to referral laboratories. BioRad Multispot HIV-1/HIV-2 Rapid Test was also performed on a subset of specimens. Of 14,559 specimens received in 20 months, 14,517 specimens were tested. Of the 14,517 specimens that were tested, a total of 279 (1.9%) specimens were CIA repeatedly reactive and 240 of the 279 confirmed by HIV-1 IFA. Thirty-nine gave IFA negative/inconclusive result and 30 were further tested for HIV-1 NAT and 36 for HIV-2 antibody. Thirteen specimens were considered false positives by CIA and 17 specimens were classified as acute infections. Eleven of 39 IFA negative/inconclusive specimens were further tested by Multispot. Five of the 11 were positive by Multispot. The fourth generation Abbott ARCHITECT HIV Ag/Ab Combo Assay identified 17 patients who may have been missed by the prior HIV-1 screening assay used at San Diego County Public Health Laboratory.

Individuals leaving prison face challenges to establishing healthy lives in the community, including opportunities to engage in behavior that puts them at risk for HIV transmission. HIV prevention case management (PCM) can facilitate linkages to services, which in turn can help remove barriers to healthy behavior. As part of a federally funded demonstration project, the community-based organization Centerforce provided 5 months of PCM to individuals leaving 3 state prisons in California. Program effects were measured by assessing changes in risk behavior, access to services, reincarnation, and program completion. Although response rates preclude definitive conclusions, HIV risk behavior did decrease. Regardless of race, age, or gender, those receiving comprehensive health services were significantly more likely to complete the program. PCM appears to facilitate healthy behavior for individuals leaving prison.

U.S. health departments have not historically used HIV surveillance data for disease control interventions with individuals, but advances in HIV treatment and surveillance are changing public health practice. Many U.S. health departments are in the early stages of implementing "Data to Care" programs to assists persons living with HIV (PLWH) with engaging in care, based on information collected for HIV surveillance. Stakeholder engagement is a critical first step for development of these programs. In Seattle-King County, Washington, the health department conducted interviews with HIV medical care providers and PLWH to inform its Data to Care program. This paper describes the key themes of these interviews and traces the evolution of the resulting program. Disease intervention specialists conducted individual, semi-structured qualitative interviews with 20 PLWH randomly selected from HIV surveillance who had HIV RNA levels >10,000 copies/mL in 2009-2010. A physician investigator conducted key informant interviews with 15 HIV medical care providers. Investigators analyzed de-identified interview transcripts, developed a codebook of themes, independently coded the interviews, and identified codes used most frequently as well as illustrative quotes for these key themes. We also trace the evolution of the program from 2010 to 2015. PLWH generally accepted the idea of the health department helping PLWH engage in care, and described how hearing about the treatment experiences of HIV seropositive peers would assist them with engagement in care. Although many physicians were supportive of the Data to Care concept, others expressed concern about potential health department intrusion on patient privacy and the patient-physician relationship. Providers emphasized the need for the health department to coordinate with existing efforts to improve patient engagement. As a result of the interviews, the Data to Care program in Seattle-King County was designed to incorporate an HIV

Introduction Swaziland’s severe HIV epidemic inspired an early national response since the late 1980s, and regular reporting of program outcomes since the onset of a national antiretroviral treatment (ART) program in 2004. We assessed effectiveness outcomes and mortality trends in relation to ART, HIV testing and counseling (HTC), tuberculosis (TB) and prevention of mother to child transmission (PMTCT). Methods Data triangulated include intervention coverage and outcomes according to program registries (2001-2010), hospital admissions and deaths disaggregated by age and sex (2001-2010) and population mortality estimates from the 1997 and 2007 censuses and the 2007 demographic and health survey. Results By 2010, ART reached 70% of the estimated number of people living with HIV/AIDS with CD4<350/mm3, with progressively improving patient retention and survival. As of 2010, 88% of health facilities providing antenatal care offered comprehensive PMTCT services. The HTC program recorded a halving in the proportion of adults tested who were HIV-infected; similarly HIV infection rates among HIV-exposed babies halved from 2007 to 2010. Case fatality rates among hospital patients diagnosed with HIV/AIDS started to decrease from 2005–6 in adults and especially in children, contrasting with stable case fatality for other causes including TB. All-cause child in-patient case fatality rates started to decrease from 2005–6. TB case notifications as well as rates of HIV/TB co-infection among notified TB patients continued a steady increase through 2010, while coverage of HIV testing and CPT for co-infected patients increased to above 80%. Conclusion Against a background of high, but stable HIV prevalence and decreasing HIV incidence, we documented early evidence of a mortality decline associated with the expanded national HIV response since 2004. Attribution of impact to specific interventions (versus natural epidemic dynamics) will require additional data from future

International health agencies have promoted nontargeted universal (opt-out) HIV screening tests in different settings, including emergency departments (EDs). We performed a systematic review and meta-analysis to assess the testing uptake of strategies (opt-in targeted, opt-in nontargeted and opt-out) to detect new cases of HIV infection in EDs. We searched the Pubmed and Embase databases, from 1984 to April 2015, for opt-in and opt-out HIV diagnostic strategies used in EDs. Randomized controlled or quasi experimental studies were included. We assessed the percentage of positive individuals tested for HIV infection in each programme (opt-in and opt-out strategies). The mean percentage was estimated by combining studies in a random-effect meta-analysis. The percentages of individuals tested in the programmes were compared in a random-effect meta-regression model. Data were analysed using stata version 12. Quality assessments were performed using the Newcastle-Ottawa Scale. Of the 90 papers identified, 28 were eligible for inclusion. Eight trials used opt-out, 18 trials used opt-in, and two trials used both to detect new cases of HIV infection. The test was accepted and taken by 75 155 of 172 237 patients (44%) in the opt-out strategy, and 73 581 of 382 992 patients (19%) in the opt-in strategy. The prevalence of HIV infection detected by the opt-out strategy was 0.40% (373 cases), that detected by the opt-in nontargeted strategy was 0.52% (419 cases), and that detected by the opt-in targeted strategy was 1.06% (52 cases). In this meta-analysis, the testing uptake of the opt-out strategy was not different from that of the opt-in strategy to detect new cases of HIV infection in EDs. © 2016 British HIV Association.

The purpose of this project was to examine the feasibility of an ongoing holistic wellness program in a residential facility treating persons with HIV/AIDS. The goal was to create a voluntary, four week holistic wellness intensive within the established inpatient behavioral health treatment program. Participants were given practicable holistic self care tools to effectively manage HIV related symptoms, general medical issues, addiction, depression, stress and anxiety. The program incorporated evidence-based holistic activities including yoga, therapeutic dance, meditation, Reiki, and reflective journaling. Narrative survey results and post-program evaluation support that an ongoing holistic wellness program within the existing treatment model is feasible and could have numerous potential beneficial effects. This project clearly exemplified the ideal opportunity for holistic nurses to implement innovative holistic interventions within the current healthcare delivery system. It is the author's observation that future studies with a larger participant group to further examine measurable benefits can lend valuable information and insight into the future development of holistic wellness programs for residential treatment facilities.

Novel 3′-Processing Integrase Activity Assay by Real-Time PCR for Screening and Identification of HIV-1 Integrase Inhibitors

Full Text Available The 3′-end processing (3′P of each viral long terminal repeat (LTR during human immunodeficiency virus type-1 (HIV-1 integration is a vital step in the HIV life cycle. Blocking the 3′P using 3′P inhibitor has recently become an attractive strategy for HIV-1 therapeutic intervention. Recently, we have developed a novel real-time PCR based assay for the detection of 3′P activity in vitro. The methodology usually involves biotinylated HIV-1 LTR, HIV-1 integrase (IN, and specific primers and probe. In this novel assay, we designed the HIV-1 LTR substrate based on a sequence with a homology to HIV-1 LTR labeled at its 3′ end with biotin on the sense strand. Two nucleotides at the 3′ end were subsequently removed by IN activity. Only two nucleotides labeled biotin were captured on an avidin-coated tube; therefore, inhibiting the binding of primers and probe results in late signals in the real-time PCR. This novel assay has successfully detected both the 3′P activity of HIV-1 IN and the anti-IN activity by Raltegravir and sodium azide agent. This real-time PCR assay has been shown to be effective and inexpensive for a high-throughput screening of novel IN inhibitors.

HIV programs have provided a major impetus for investments in surveillance data, with 5-10% of HIV program budgets recommended to support data. However there are questions concerning the sustainability of these investments. The Sustainable Development Goals have consolidated health into one goal and communicable diseases into one target (Target 3.3). Sustainable Development Goals now introduce targets focused specifically on data (Targets 17.18 and 17.19). Data are seen as one of the three systemic issues (in Goal 17) for implementing Sustainable Development Goals, alongside policies and partnerships. This paper reviews the surveillance priorities in the context of the Sustainable Development Goals and highlights the shift from periodic measurement towards sustainable disaggregated, real-time, case, and patient data, which are used routinely to improve programs. Finally, the key directions in developing person-centered monitoring systems are assessed with country examples. The directions contribute to the Sustainable Development Goal focus on people-centered development applied to data. ©Daniel Low-Beer, Mary Mahy, Francoise Renaud, Txema Calleja.

Full Text Available Abstract The HIV/AIDS pandemic is primarily caused by HIV-1. Another virus type, HIV-2, is found mainly in West African countries. We hypothesized that population migration and mobility in Africa may have facilitated the introduction and spreading of HIV-2 in Mozambique. The presence of HIV-2 has important implications for diagnosis and choice of treatment of HIV infection. Hence, the aim of this study was to estimate the prevalence of HIV-2 infection and its genotype in Maputo, Mozambique. HIV-infected individuals (N = 1,200 were consecutively enrolled and screened for IgG antibodies against HIV-1 gp41 and HIV-2 gp36 using peptide-based enzyme immunoassays (pepEIA. Specimens showing reactivity on the HIV-2 pepEIA were further tested using the INNO-LIA immunoblot assay and HIV-2 PCR targeting RT and PR genes. Subtype analysis of HIV-2 was based on the protease gene. After screening with HIV-2 pepEIA 1,168 were non-reactive and 32 were reactive to HIV-2 gp36 peptide. Of this total, 30 specimens were simultaneously reactive to gp41 and gp36 pepEIA while two samples reacted solely to gp36 peptide. Only three specimens containing antibodies against gp36 and gp105 on the INNO-LIA immunoblot assay were found to be positive by PCR to HIV-2 subtype A. The proportion of HIV-2 in Maputo City was 0.25% (90%CI 0.01-0.49. The HIV epidemic in Southern Mozambique is driven by HIV-1, with HIV-2 also circulating at a marginal rate. Surveillance program need to improve HIV-2 diagnosis and consider periodical survey aiming to monitor HIV-2 prevalence in the country.

Full Text Available The recent approval of 4th generation HIV tests has forced many laboratories to decide whether to shift from 3rd to these tests. There are limited published studies on the comparative evaluation of these two different assays. We compare the performance of fourth-generation electrochemiluminescence immunoassay (ChIA and third-generation enzyme linked immunosorbent assay (EIA for human immunodeficiency virus (HIV screening and gauge whether the shift from EIA to ChIA could be better in a multiethnic region of China.We identified a large number of routine specimens (345,492 using two different assays from Jan 2008 to Aug 2011 in a teaching hospital with high sample throughput. Of the 344,596 specimens with interpretable HIV test results, 526(0.23% of 228,761 using EIA and 303(0.26% of 115,835 using ChIA were HIV-1 positive. The false-positive rate of EIA was lower than that of ChIA [0.03% vs. 0.08%, odds ratio 0.33 (95% confidence interval 0.24, 0.45]. The positive predictive value (PPV of EIA (89.6% was significantly higher than that of ChIA (76.1% (<0.001, reflecting the difference between the two assays. The clinical sensitivities of two assays in this study were 99.64% for EIA and 99.88% for ChIA.Caution is needed before shifting from 3rd to 4th generation HIV tests. Since none of these tests are perfect, different geographic and ethnic area probably require different considerations with regard to HIV testing methods, taking into account the local conditions.

HIV-1 protease (PR) represents one of the primary targets for developing antiviral agents for the treatment of HIV-infected patients. To identify novel PR inhibitors, a label-free, high-throughput mass spectrometry (HTMS) assay was developed using the RapidFire platform and applied as an orthogonal assay to confirm hits identified in a fluorescence resonance energy transfer (FRET)-based primary screen of > 1 million compounds. For substrate selection, a panel of peptide substrates derived from natural processing sites for PR was evaluated on the RapidFire platform. As a result, KVSLNFPIL, a new substrate measured to have a ~ 20- and 60-fold improvement in k cat/K m over the frequently used sequences SQNYPIVQ and SQNYPIV, respectively, was identified for the HTMS screen. About 17% of hits from the FRET-based primary screen were confirmed in the HTMS confirmatory assay including all 304 known PR inhibitors in the set, demonstrating that the HTMS assay is effective at triaging false-positives while capturing true hits. Hence, with a sampling rate of ~7 s per well, the RapidFire HTMS assay enables the high-throughput evaluation of peptide substrates and functions as an efficient tool for hits triage in the discovery of novel PR inhibitors. © 2015 Society for Laboratory Automation and Screening.

Basic elements for breast screening programs for Rwanda

Abenanye, Emmanuel

Mammography refers to the X-ray examination of the human breast, and is considered the single most important diagnostic tool in the early detection of breast cancer, which is by far the most common cancer among women. There is good evidence from clinical trials, that mammographic screening can reduce the breast cancer mortality with about 30%. The side effects include a small and age related risk of carcinogenesis due to the exposure of the glandular tissues in the breast to ionizing radiation. As for all X-ray examinations, and of special importance when investigating large populations of asymptomatic women, the relationship between radiation risk and diagnostic accuracy in mammography must be optimized. The overall objective of this thesis was to investigate and improve methods for average glandular dose (AGD) and image quality evaluation in mammography and provide some practical guidance. To assess the behavioral factors influencing breast screening the best set up of the mammography unit as well as equipment construction and the skills of people operating the machines in terms of the radiation protection screening programs. There has been doubts about the efficiency of so called service screening, i.e. routine screening programs (Sjonell and Stahle, 1999), but there is evidence suggesting a reduction of breast cancer mortality similar to that observed in the randomised trials (Duffy et al. 2002). However no study has been carried out in Rwanda of this nature to see what are the basic breast screening elements and behavioral elements that influence it. Therefore, the factors that influence women's mammography screening behavior is an important issue to be uncovered, in order to facilitate the understanding of such a behavior. This report sets out to investigate the factors that influence participation in mammography screening in Rwanda. Such an investigation aims to raise the awareness of health care providers of the factors that influence Rwanda's women

Fall prevention is an important way to prevent fractures in person with osteoporosis. We developed and implemented a fall screening program in the context of routine osteoporosis care. This program was found to be feasible and showed that a significant proportion of persons with osteoporosis are at risk of falling. Falls are the most common cause of fracture in persons with osteoporosis. However, osteoporosis care rarely includes assessment and prevention of falling. We thus sought to assess the feasibility of a fall screening and management program integrated into routine osteoporosis care. The program was developed and offered to patients with osteoporosis or osteopenia seen at an outpatient clinic between May 2015 and May 2016. Feasibility was measured by physical therapist time required to conduct screening and ease of integrating the screening program into the usual clinic workflow. Self-report responses and mobility testing were conducted to describe the fall and fracture risk profile of osteoporosis patients screened. Effects on fall-related care processes were assessed via chart abstraction of patient participation in fall prevention exercise. Of the 154 clinic patients who presented for a clinic visit, 68% met screening criteria and completed in two thirds of persons. Screening was completed in a third of the time typically allotted for traditional PT evaluations and did not interfere with clinic workflow. Forty percent of those screened reported falling in the last year, and over half had two or more falls in the past year. Over half reported a balance or lower extremity impairment, and over 40% were below norms on one or more performance tests. Most patients who selected a group exercise fall prevention program completed all sessions while only a quarter completed either supervised or independent home-based programs. Implementation of a fall risk screening program in an outpatient osteoporosis clinic appears feasible. A substantial proportion of people

Full Text Available Community-based care (CBC can increase access to key services for people affected by HIV/AIDS through the mobilization of community interests and resources and their integration with formal health structures. Yet, the lack of a systematic framework for analysis of CBC focused on HIV/AIDS impedes our ability to understand and study CBC programs. We sought to develop taxonomy of CBC programs focused on HIV/AIDS in resource-limited settings in an effort to understand their key characteristics, uncover any gaps in programming, and highlight the potential roles they play. Our review aimed to systematically identify key CBC programs focused on HIV/AIDS in resource-limited settings. We used both bibliographic database searches (Medline, CINAHL, and EMBASE for peer-reviewed literature and internet-based searches for gray literature. Our search terms were ‘HIV’ or ‘AIDS’ and ‘community-based care’ or ‘CBC’. Two co-authors developed a descriptive taxonomy through an iterative, inductive process using the retrieved program information. We identified 21 CBC programs useful for developing taxonomy. Extensive variation was observed within each of the nine categories identified: region, vision, characteristics of target populations, program scope, program operations, funding models, human resources, sustainability, and monitoring and evaluation strategies. While additional research may still be needed to identify the conditions that lead to overall program success, our findings can help to inform our understanding of the various aspects of CBC programs and inform potential logic models for CBC programming in the context of HIV/AIDS in resource-limited settings. Importantly, the findings of the present study can be used to develop sustainable HIV/AIDS-service delivery programs in regions with health resource shortages.

Background Cervical cancer is a major public health problem in resource-limited settings, particularly among HIV-infected women. Given the challenges of cytology-based approaches, the efficiency of new screening programs need to be assessed. Setting Community and hospital-based clinics in Gaborone, Botswana. Objective To determine the feasibility, and efficiency of the “See and Treat” approach using Visual Inspection Acetic Acid (VIA) and Enhanced Digital Imaging (EDI) for cervical cancer prevention in HIV-infected women. Methods A two-tier community-based cervical cancer prevention program was implemented. HIV-infected women were screened by nurses at the community using the VIA/EDI approach. Low-grade lesions were treated with cryotherapy on the same visit. Women with complex lesions were referred to our second tier, specialized clinic for evaluation. Weekly quality control assessments were performed by a specialist in collaboration with the nurses on all pictures taken. Results From March 2009 through January 2011, 2,175 patients were screened for cervical cancer at our community-based clinic. 253 (11.6%) were found to have low-grade lesions and received same-day cryotherapy. 1,347 (61.9%) women were considered to have a normal examination and 575 (27.3%) were referred for further evaluation and treatment. Of the 1,347 women initially considered to have normal exams, 267 (19.8%) were recalled based on weekly quality control assessments. 210 (78.6%) of the 267 recalled women and 499 (86.8%) of the 575 referred women were seen at the referral clinic. Of these 709 women, 506 (71.4%) required additional treatment. Overall, 264 CIN stage 2 or 3 were identified and treated, and six micro-invasive cancers identified were referred for further management. Conclusions Our “See and Treat” cervical cancer prevention program using the VIA/EDI approach is a feasible, high-output and high-efficiency program, worthy of considering as an additional cervical cancer

following scientific evidence produced in numerous studies, as well as national and international guidelines, organized cervical cancer screening programs in Italy have gradually introduced the HPV test as primary screening test, replacing cytology. As public health interventions, screening programs must ensure equity, improvement in quality of life, and adequate information for the population involved with regards to benefits and possible risks; therefore, it is essential for quality to be constantly checked at every phase of the project.The Italian Cervical Screening Group (Gruppo Italiano per lo Screening Cervicale, GISCi) has written a handbook for the calculation and interpretation of cervical screening program monitoring indicators that take into account the new protocol based on primary HPV test with cytology triage. based on the European guidelines and Italian recommendations on primary HPVbased screening, the working group, which includes professionals from all the fields involved in cervical screening, identified the essential points needed to monitor the screening process, the accuracy of individual tests, and early outcomes, defining a specific indicator for each aspect. The indicators were grouped as follows: baseline indicators, indicators for test repeat after one year, cumulative indicators, and waiting times. For every indicator, the source of data, calculation formula, any standards or critical thresholds, and interpretation were defined. The standards are based on the results of NTCC trials or Italian pilot studies. the main indicators proposed for the organization are the following: number of invitations, compliance with first invitation, with one-year test repeat and with colposcopy; for test and process accuracy, a cohort approach was utilised, where indicators are based on women who must be followed for at least one year, so as to integrate the results obtained after the first HPV test with the outcome of the test's repetition after one year

Full Text Available Rapid easy-to-use HIV tests offer opportunities to increase HIV testing among populations at risk of infection. We used the OraQuick Rapid HIV-1/2 antibody test (OraQuick in the Bangkok Tenofovir Study, an HIV pre-exposure prophylaxis trial among people who inject drugs.The Bangkok Tenofovir Study was a randomized, double-blind, placebo-controlled trial. We tested participants' oral fluid for HIV using OraQuick monthly and blood using a nucleic-acid amplification test (NAAT every 3 months. We used Kaplan-Meier methods to estimate the duration from a positive HIV NAAT until the mid-point between the last non-reactive and first reactive oral fluid test and proportional hazards to examine factors associated with the time until the test was reactive.We screened 3678 people for HIV using OraQuick. Among 447 with reactive results, 436 (97.5% were confirmed HIV-infected, 10 (2.2% HIV-uninfected, and one (0.2% had indeterminate results. Two participants with non-reactive OraQuick results were, in fact, HIV-infected at screening yielding 99.5% sensitivity, 99.7% specificity, a 97.8% positive predictive value, and a 99.9% negative predictive value. Participants receiving tenofovir took longer to develop a reactive OraQuick (191.8 days than participants receiving placebo (16.8 days (p = 0.02 and participants infected with HIV CRF01_AE developed a reactive OraQuick earlier than participants infected with other subtypes (p = 0.04.The oral fluid HIV test performed well at screening, suggesting it can be used when rapid results and non-invasive tools are preferred. However, participants receiving tenofovir took longer to develop a reactive oral fluid test result than those receiving placebo. Thus, among people using pre-exposure prophylaxis, a blood-based HIV test may be an appropriate choice.ClinicalTrials.gov NCT00119106.

Health utility (HU) is essential to understanding the effects of HIV infection as a chronic disease. No HU data on pregnant women living with human immunodeficiency virus (HIV) in Yunnan Province are available. This study aims to construct a database on HU and explore factors associated with HU by pregnant women living with HIV/acquired immunodeficiency syndrome (AIDS) who were enrolled in the Prevention of mother-to-child transmission of HIV (PMTCT) programs in Yunnan Province. A cross-sectional study was conducted in Yunnan Province on pregnant women living with HIV who were selected by convenience sampling. Sociodemographic, HIV-related, social support, and HU data were collected through face-to-face interviews. The European quality of life five-dimensional three-level (EQ-5D-3L) questionnaire and the social support rate scale (SSRS) were applied. One hundred and one pregnant women (mean age of 30.4 ± 5.1 years) participated in the survey. The mean EQ-5D index score and the EQ visual analogue scale (EQ-VAS) score of participants were 0.77 (95% confidence interval [CI] 0.74-0.79) and 75.77 (95% CI 75.00-80.00), respectively. The effect of social support on HU was maintained significant difference even after adjusting for such factors as education level, household income per year, and HIV disclosure, demonstrating a significant difference within EQ-5D index scores and EQ-VAS scores. Pregnant women living with HIV/AIDS who were enrolled in PMTCT programs reported the same level of HU as other patients living with HIV/AIDS. Integrating measurements of HU by using the EQ-5D-3L questionnaire could be helpful for economic evaluation of the PMTCT program. This study also suggests a potential benefit of appropriate social support. Copyright © 2018. Published by Elsevier Inc.

Certified health educator (CHE)-based HIV counseling and testing typically focus on HIV and sexually transmitted infection (STI) prevention only. A quality improvement initiative examined integrating assessment of reproductive life plans, counseling about pregnancy prevention, and contraception referral into a CHE-based HIV testing program. Between February 2014 and January 2017, in one urban pediatric primary care clinic serving patients aged 0-25, CHEs assessed sexual history, HIV risk, short-term (i.e., the next 6-12 months) pregnancy desire, and current contraception method and satisfaction among patients aged 13-25 who had ever had vaginal sex, using a standardized questionnaire. Data were analyzed using a de-identified administrative dataset that also tracked referrals to initiate contraception and actual method initiation. Of 1,211 patients, most (96%) reported no short-term pregnancy or partner pregnancy desire. Use of less effective or no contraception, as well as method dissatisfaction, was common. A high proportion of female patients referred to new methods opted for more effective methods (62%) and initiated these methods (76%); a high proportion of male patients opted for receipt of condoms (67%). Patients reporting short-term pregnancy desire reported higher rates of previous pregnancy and STIs. Program findings highlight the potential benefit of integrating assessment for and counseling about pregnancy prevention in a CHE-based HIV testing program. This can more effectively address the needs of patients with concomitant risks of STI/HIV and unintended pregnancy, and link patients who do not desire pregnancy to more effective methods.

Sgaier, Sema K.; Reed, Jason B.; Thomas, Anne; Njeuhmeli, Emmanuel

2014-01-01

Voluntary medical male circumcision (VMMC) is capable of reducing the risk of sexual transmission of HIV from females to males by approximately 60%. In 2007, the WHO and the Joint United Nations Programme on HIV/AIDS (UNAIDS) recommended making VMMC part of a comprehensive HIV prevention package in countries with a generalized HIV epidemic and low rates of male circumcision. Modeling studies undertaken in 2009–2011 estimated that circumcising 80% of adult males in 14 priority countries in Eastern and Southern Africa within five years, and sustaining coverage levels thereafter, could avert 3.4 million HIV infections within 15 years and save US$16.5 billion in treatment costs. In response, WHO/UNAIDS launched the Joint Strategic Action Framework for accelerating the scale-up of VMMC for HIV prevention in Southern and Eastern Africa, calling for 80% coverage of adult male circumcision by 2016. While VMMC programs have grown dramatically since inception, they appear unlikely to reach this goal. This review provides an overview of findings from the PLOS Collection “Voluntary Medical Male Circumcision for HIV Prevention: Improving Quality, Efficiency, Cost Effectiveness, and Demand for Services during an Accelerated Scale-up.” The use of devices for VMMC is also explored. We propose emphasizing management solutions to help VMMC programs in the priority countries achieve the desired impact of averting the greatest possible number of HIV infections. Our recommendations include advocating for prioritization and funding of VMMC, increasing strategic targeting to achieve the goal of reducing HIV incidence, focusing on programmatic efficiency, exploring the role of new technologies, rethinking demand creation, strengthening data use for decision-making, improving governments' program management capacity, strategizing for sustainability, and maintaining a flexible scale-up strategy informed by a strong monitoring, learning, and evaluation platform.

Objectives. We investigated attitudes about and acceptance of anal Papanicolaou (Pap) screening among men who have sex with men (MSM). Methods. Free anal Pap screening (cytology) was offered to 1742 MSM in the Multicenter AIDS Cohort Study, who reported history of, attitudes about, and experience with screening. We explored predictors of declining screening with multivariate logistic regression. Results. A history of anal Pap screening was uncommon among non–HIV-infected MSM, but more common among HIV-infected MSM (10% vs 39%; P < .001). Most participants expressed moderate or strong interest in screening (86%), no anxiety about screening (66%), and a strong belief in the utility of screening (65%). Acceptance of screening during this study was high (85%) across all 4 US sites. Among those screened, most reported it was “not a big deal” or “not as bad as expected,” and 3% reported that it was “scary.” Declining to have screening was associated with Black race, anxiety about screening, and low interest, but not age or HIV status. Conclusions. This study demonstrated high acceptance of anal Pap screening among both HIV-infected and non–HIV-infected MSM across 4 US sites. PMID:23865658

HIV replication assays are important tools for HIV drug discovery efforts. Here, we present a full HIV replication system (EASY-HIT) for the identification and analysis of HIV inhibitors. This technology is based on adherently growing HIV-susceptible cells, with a stable fluorescent reporter gene activated by HIV Tat and Rev. A fluorescence-based assay was designed that measures HIV infection by two parameters relating to the early and the late phases of HIV replication, respectively. Validation of the assay with a panel of nine reference inhibitors yielded effective inhibitory concentrations consistent with published data and allowed discrimination between inhibitors of early and late phases of HIV replication. Finer resolution of the effects of reference drugs on different steps of HIV replication was achieved in secondary time-of-addition assays. The EASY-HIT assay yielded high Z' scores (>0.9) and signal stabilities, confirming its robustness. Screening of the LOPAC(1280) library identified 10 compounds (0.8%), of which eight were known to inhibit HIV, validating the suitability of this assay for screening applications. Studies evaluating anti-HIV activities of natural products with the EASY-HIT technology led to the identification of three novel inhibitory compounds that apparently act at different steps of HIV-1 replication. Furthermore, we demonstrate successful evaluation of plant extracts for HIV-inhibitory activities, suggesting application of this technology for the surveillance of biological extracts with anti-HIV activities. We conclude that the EASY-HIT technology is a versatile tool for the discovery and characterization of HIV inhibitors.

Multiple advisory groups now recommend that high-risk smokers be screened for lung cancer by low-dose computed tomography. Given that the development of lung cancer screening programs will face many of the same issues that have challenged other cancer screening programs, the National Cancer Institute-funded Population-based Research Optimizing Screening through Personalized Regimens (PROSPR) consortium was used to identify lessons learned from the implementation of breast, cervical, and colorectal cancer screening that should inform the introduction of lung cancer screening. These lessons include the importance of developing systems for identifying and recruiting eligible individuals in primary care, ensuring that screening centers are qualified and performance is monitored, creating clear communication standards for reporting screening results to referring physicians and patients, ensuring follow-up is available for individuals with abnormal test results, avoiding overscreening, remembering primary prevention, and leveraging advances in cancer genetics and immunology. Overall, this experience emphasizes that effective cancer screening is a multistep activity that requires robust strategies to initiate, report, follow up, and track each step as well as a dynamic and ongoing oversight process to revise current screening practices as new evidence regarding screening is created, new screening technologies are developed, new biological markers are identified, and new approaches to health care delivery are disseminated.

Evidence documenting the global burden of disease from viral hepatitis was essential for the World Health Assembly to endorse the first Global Health Sector Strategy (GHSS) on viral hepatitis in May 2016. The GHSS on viral hepatitis proposes to eliminate viral hepatitis as a public health threat by 2030. The GHSS on viral hepatitis is in line with targets for HIV infection and tuberculosis as part of the Sustainable Development Goals. As coordination between hepatitis and HIV programs aims to optimize the use of resources, guidance is also needed to align the strategic information components of the 2 programs. The World Health Organization monitoring and evaluation framework for viral hepatitis B and C follows an approach similar to the one of HIV, including components on the following: (1) context (prevalence of infection), (2) input, (3) output and outcome, including the cascade of prevention and treatment, and (4) impact (incidence and mortality). Data systems that are needed to inform this framework include (1) surveillance for acute hepatitis, chronic infections, and sequelae and (2) program data documenting prevention and treatment, which for the latter includes a database of patients. Overall, the commonalities between HIV and hepatitis at the strategic, policy, technical, and implementation levels justify coordination, strategic linkage, or integration, depending on the type of HIV and viral hepatitis epidemics. Strategic information is a critical area of this alignment under the principle of what gets measured gets done. It is facilitated because the monitoring and evaluation frameworks for HIV and viral hepatitis were constructed using a similar approach. However, for areas where elimination of viral hepatitis requires data that cannot be collected through the HIV program, collaborations are needed with immunization, communicable disease control, tuberculosis, and hepatology centers to ensure collection of information for the remaining indicators. �

Full Text Available Abstract Background The last decade has seen enormous advances in HIV treatment and care, but how to implement scaled up HIV testing, prevention, and treatment in low-income areas still presents a formidable public health challenge. South China faces expanding syphilis and sexually transmitted HIV epidemics, but health systems characteristics important for scaling up syphilis and HIV testing have not been defined. Methods A purposive sample to ensure public, private, and public-private hybrid STI clinic inclusion was selected in a South China city. Eight key informant interviews were conducted with the STI clinic manager, followed by eight focus group discussions with physicians. Data collection relied on a semi-structured format that included questions in each of the following domains: 1 clinical facilities; 2 laboratory capacity with a focus on syphilis/HIV diagnosis; 3 clinic personnel; 4 physical space with a focus on locations to disclose confidential results; 5 financial support. Results Public STI clinics had free syphilis testing/treatment and laboratory facilities to perform essential syphilis and HIV tests. However, despite serving a large number of STI patients, private STI clinics lacked nontreponemal syphilis testing, HIV testing, and had fewer connections to the public health infrastructure. Formally trained assistant physicians were 2.5 times as common as physicians at STI clinics. Only one of the 8 sites had onsite voluntary counseling and testing (VCT services available. Conclusion These STI case studies reveal the potential for expanding integrated syphilis/HIV services at public STI clinics in China. More health services research is needed to guide scale-up of syphilis/HIV testing in China.

Full Text Available Abstract Background U.S. health departments have not historically used HIV surveillance data for disease control interventions with individuals, but advances in HIV treatment and surveillance are changing public health practice. Many U.S. health departments are in the early stages of implementing “Data to Care” programs to assists persons living with HIV (PLWH with engaging in care, based on information collected for HIV surveillance. Stakeholder engagement is a critical first step for development of these programs. In Seattle-King County, Washington, the health department conducted interviews with HIV medical care providers and PLWH to inform its Data to Care program. This paper describes the key themes of these interviews and traces the evolution of the resulting program. Methods Disease intervention specialists conducted individual, semi-structured qualitative interviews with 20 PLWH randomly selected from HIV surveillance who had HIV RNA levels >10,000 copies/mL in 2009–2010. A physician investigator conducted key informant interviews with 15 HIV medical care providers. Investigators analyzed de-identified interview transcripts, developed a codebook of themes, independently coded the interviews, and identified codes used most frequently as well as illustrative quotes for these key themes. We also trace the evolution of the program from 2010 to 2015. Results PLWH generally accepted the idea of the health department helping PLWH engage in care, and described how hearing about the treatment experiences of HIV seropositive peers would assist them with engagement in care. Although many physicians were supportive of the Data to Care concept, others expressed concern about potential health department intrusion on patient privacy and the patient-physician relationship. Providers emphasized the need for the health department to coordinate with existing efforts to improve patient engagement. As a result of the interviews, the Data to Care

2008-05-01

Our state Breast and Cervical Cancer Program (BCCP) has previously reported a paucity of data supporting breast screening for asymptomatic women younger than 40 (cancer detection rate of .25% per screening-year). In partnership with the local Affiliate of the Susan G. Komen for the Cure Foundation, we began a targeted "screening" program to evaluate women younger than 40 referred for symptoms or other concerns. Retrospective data review of program results, including demographics, symptoms, evaluations performed, and outcomes. A total of 176 women, ages 16 to 39 years, were referred to the BCCP/Komen program. Of the women with documented presenting symptoms, the most common was breast lump (81%). Evaluation triggered 75 surgical referrals and 69 biopsies, yielding 16 cancers (a biopsy positive rate of 23% and overall cancer detection rate from the program of 9%). For women younger than age 40, targeted breast cancer screening is a more efficient utilization of screening resources, with a higher cancer detection rate than asymptomatic screening.
