Acceptability and safety of thermal ablation for the treatment of precancerous cervical lesions in Honduras.

OBJECTIVE: To evaluate the acceptability and safety of thermal ablation (TA) for the treatment of precancerous cervical lesions in women in Honduras. METHODS: Human papillomavirus (HPV) and visual inspection with acetic acid (VIA) screen-positive eligible women received TA. After treatment, women rated the level of pain experienced during treatment using the Wong-Baker FACES® pain-rating scale from 0 to 10. Short-term safety outcomes that could require medical attention were assessed one month after treatment. RESULTS: A total of 319 women received TA treatment. The average pain rating was 2.5 (95% CI: 2.3-2.8), and 85% rated their pain levels as less than 6. No significant differences in low (below 6) or high (6 and above) pain were found by age or number of biopsies performed, but there was a significant difference by the number of TA applications (P < 0.01). When asked if they would recommend this treatment, all women said they would. At the one-month follow-up visit, the most common reported discomforts were bleeding (10%) and cramping (8.4%); 11 women reported severe lower abdominal pain, and none required medical attention. CONCLUSIONS: TA is safe and acceptable to patients as a treatment option for precancerous cervical lesions in low-resource settings.

OBJECTIF: Evaluer l'acceptabilité et la sécurité de l'ablation thermique (AT) pour le traitement des lésions cervicales précancéreuses chez les femmes au Honduras. MÉTHODES: Les femmes éligibles, portant le virus du papillome humain (VPH) et avec une inspection visuelle positive au test de dépistage à l'acide acétique (IVA) ont reçu une AT. Après le traitement, les femmes ont estimé le niveau de douleur ressenti au cours du traitement à l'aide de l'échelle d'évaluation de la douleur Wong-Baker FACES® de 0 à 10. Les résultats de sécurité à court terme pouvant nécessiter une attention médicale ont été évalués un mois après le traitement. RÉSULTATS: 319 femmes ont reçu un traitement d'AT. L'estimation moyenne de la douleur était de 2,5 (IC95%: 2,3-2,8) et 85% estimaient que leur niveau de douleur était inférieur à 6. Aucune différence significative dans la douleur faible (moins de 6) ou élevée (6 et plus) n'a été constatée en fonction de l'âge ou du nombre de biopsies réalisées, mais il y avait une différence significative selon le nombre d'applications d'AT (P < 0,01). Lorsqu'on leur a demandé si elles recommanderaient ce traitement, toutes les femmes ont répondu qu'elles le feraient. Lors de la visite de suivi à un mois, les malaises les plus fréquents signalés étaient les saignements (10%) et les crampes (8,4%). Onze femmes ont rapporté des douleurs sévères dans le bas de l'abdomen et aucune n'a nécessité de soins médicaux. CONCLUSIONS: L'AT est sûre et acceptable pour les patientes comme option de traitement pour les lésions cervicales précancéreuses dans les régions à faibles ressources.

Cost for sickle cell disease screening using isoelectric focusing with dried blood spot samples and estimation of price thresholds for a point-of-care test in Uganda.

BACKGROUND: Early identification through newborn screening is the first step in active management of sickle cell disease (SCD). Uganda currently screens newborns and infants under 2 years for SCD in high HIV-burden districts using isoelectric focusing with dried blood spot samples. Our analysis sought to estimate the costs per child screened for SCD using this method in Uganda and then to use those data to estimate the price threshold for screening with a point-of-care (POC) test. METHODS: We estimated the financial and economic costs per child screened for SCD using data from health facilities and the Central Public Health Laboratory. These costs included sample collection, transportation, and laboratory processing. Price thresholds for a POC test were estimated using two scenarios. RESULTS: The price threshold of an SCD POC test used for diagnosis would be $3.77 when taking into account only financial costs and $5.14 when taking into account economic costs. Thresholds for a POC test used for screening would be $3.07-$3.51 and $4.38-$5.09, respectively, depending on test specificity. CONCLUSION: The price threshold of a POC test for SCD will depend on the assumptions on how it will be used - either as a screening or diagnostic test. If used for screening, test specificity will have significant impact. Results from this type of costing study can allow developers to incorporate quantitatively estimated price thresholds for innovative products into target product profiles early in the product development cycle.

Ugandan providers' views on the acceptability of contraceptive self-injection for adolescents: a qualitative study.

BACKGROUND: Self-injection of subcutaneous depot medroxyprogesterone acetate may offer greater discretion and increase access to injectable contraception, particularly for those who face challenges accessing clinic services. In particular, unmarried adolescents often encounter stigma when seeking services, and may also lack the financial means to travel to clinics on the quarterly basis that injectable contraception requires. Whether self-injection is offered to women on a wide scale basis, and to adolescents specifically, will depend in part upon the willingness of providers to train clients of diverse ages and educational backgrounds. This study explores the views of providers with regard to self-injection as an option for women and adolescents in Uganda. METHODS: In-depth qualitative interviews were conducted with family planning providers in Gulu district, to understand their views on injectable self-injection for women, with a specific focus on unmarried adolescents ages 15 to 19 years. The in-depth interviews, which lasted up to 60 min were audio-recorded, translated and transcribed simultaneously, and analyzed using Atlas.ti software to identify key themes and common perspectives. RESULTS: A total of 40 health care providers were interviewed with equal numbers of each type (public, NGO, and private clinics, pharmacies, and community-based health workers). While most providers were receptive to self-injection for adult women, fewer than half were supportive of adolescent self-injection. Their reservations focused on age, marital status and parity concerns around adolescent use of the injectable more broadly, and concerns about the ability of adolescents to self-inject safely. CONCLUSIONS: Self-injection presents an opportunity to reduce the enormous burden on the public sector health system in Uganda, which is particularly compounded by the heavy reliance on injectable contraception requiring quarterly clinic visits. The results of this study reveal a level of cautious support for self-injection among providers when it comes to self-injection by adult women. With respect to adolescent clients, family planning policymakers and program implementers should design, implement, and evaluate self-injection interventions with the needs of adolescent clients uppermost in mind, recognizing that extra attention will likely be needed to reduce provider-imposed restrictions on adolescent access to this injectable delivery modality.

Opportunities and challenges for introducing HPV testing for cervical cancer screening in sub-Saharan Africa.

To protect women against cervical cancer, the World Health Organization recommends that women aged 30 to 49 years be screened with tests that detect human papillomavirus (HPV). If the countries that have the greatest burden of this disease-especially those in sub-Saharan Africa-are not to be left behind, we must understand the challenges they face and identify measures that can help them take full advantage now of innovations that are transforming screening services in wealthier countries. We reviewed policy documents and published literature related to Kenya, Tanzania, and Uganda, and met with key personnel from government and nongovernmental organizations. National policy makers understand the value of HPV testing in terms of its superior sensitivity and the programmatic advantages that could result from using self-collected samples. However, while these countries have national cervical cancer prevention strategies, and some have national departments or units for cervical cancer prevention, screening is rare, funding scarce, and quality low. Age guidelines are not strictly followed, with scarce resources being used to screen many women younger than the recommended ages. Published evidence of the benefits of HPV testing-including performance, safety, and cost-effectiveness-must be provided to ministry of health leaders, along with information on anticipated costs for training personnel, purchasing supplies, providing facility space, and maintaining test kits. Despite the obstacles, a joint effort on the part of global and national stakeholders to introduce molecular screening methods can bring better protection to the women who need it most.

Continuation of injectable contraception when self-injected vs. administered by a facility-based health worker: a nonrandomized, prospective cohort study in Uganda.

OBJECTIVE: The purpose of this study was to compare 12-month continuation rates for subcutaneous depot medroxyprogesterone acetate (DMPA-SC) administered via self-injection and DMPA-IM administered by a health worker in Uganda. STUDY DESIGN: Women seeking injectable contraception at participating health facilities were offered the choice of self-injecting DMPA-SC or receiving an injection of DMPA-IM from a health worker. Those opting for self-injection were trained one-on-one. They self-injected under supervision and took home three units, a client instruction guide and a reinjection calendar. Those opting for DMPA-IM received an injection and an appointment card for the next facility visit in 3 months. We interviewed participants at baseline (first injection) and after 3 (second injection), 6 (third injection) and 9 (fourth injection) months, or upon discontinuation. We used Kaplan-Meier methods to estimate continuation probabilities, with a log-rank test to compare differences between groups. A multivariate Cox regression identified factors correlated with discontinuation. RESULTS: The 12-month continuation rate for the 561 women self-injecting DMPA-SC was .81 [95% confidence interval (CI) .78-.84], and for 600 women receiving DMPA-IM from a health worker, it was .65 (95% CI .61-.69), a significant difference at the .05 level. There were no differences in pregnancy rates or side effects. The multivariate analysis revealed that, controlling for covariates, self-injecting reduced the hazard for discontinuing by 46%. A significant interaction between injection group and age suggests that self-injection may help younger women continue injectable use. CONCLUSIONS: The significant difference in 12-month continuation between women self-injecting DMPA-SC and women receiving DMPA-IM from a health worker - which remains significant in a multivariate analysis - suggests that self-injection may improve injectable contraceptive continuation. IMPLICATIONS: While injectable contraceptives are popular throughout much of sub-Saharan Africa, they have high rates of discontinuation. This study is the second from an African country to demonstrate that self-injection may improve injectable continuation rates and may do so without increasing the risk of pregnancy or adverse events.

"I think it is right": a qualitative exploration of the acceptability and desired future use of oral swab and finger-prick HIV self-tests by lay users in KwaZulu-Natal, South Africa.

BACKGROUND: The uptake of HIV testing has increased in sub-Saharan Africa over the past three decades. However, the proportion of people aware of their HIV status remains lower than required to change the pandemic. HIV self-testing (HIVST) may meet this gap. Assessment of readiness for and the acceptability of HIVST by lay users in South Africa is limited. This paper presents results from a formative study designed to assess the perceived usability and acceptability of HIVST among lay users using several self-test prototypes. Fifty lay users were purposively selected from rural and peri-urban KwaZulu-Natal, South Africa. Acceptability of HIVST was assessed using a simple post-test quantitative assessment tool addressing confidence, ease-of-use, intended future use and willingness to pay. In-depth qualitative interviews explored what participants felt about the HIVST and why, their willingness to recommend and how much they would pay for a test. RESULTS: The key finding is that there is high acceptability regardless of self-test prototype. Acceptability is framed by two domains: usability and perceived need. Perceived usability was explored through perceived ease of use, which, regardless of actual correct usage, was reported by many of the respondents. Acceptability is influenced by perceived need, expressed by many who felt that the need for the self-test to protect privacy and autonomy. Ease of access and widespread availability of the test, not at a significant cost, were also important factors. Many participants would recommend self-test use to others and also indicated that they would choose to conduct the test again if it was free while some also indicated being willing to buy a test. CONCLUSIONS: The positive response and readiness amongst lay users for an HIVST in this context prototype suggests that there would be a ready and willing market for HIVST. For scalability and sustainability usability, including access and availability that are here independent indications of acceptability, should be considered. So too should the desire for future use, as an additional factor pointing to acceptability. The results show high acceptability in all of these areas domains and a general interest in HIVST amongst lay users in a community in KwaZulu-Natal.

Elucidation of shared and specific white matter findings underlying psychopathology clusters in schizophrenia.

BACKGROUND: Schizophrenia is associated with diverse white matter (WM) brain abnormalities. In this study, we sought to examine the WM microstructural findings which underlie clinical psychopathology clusters in schizophrenia and hypothesized that these symptom clusters are associated with common and unique WM tracts. METHODS: Overall, 76 healthy controls (HC), and 148 patients with schizophrenia (SZ) were recruited and severity of symptomatology in schizophrenia was assessed using the Positive and Negative Syndrome Scale. WM fractional anisotropy (FA) values were extracted from their diffusion tensor images. Psychopathology clusters were first determined using factor analysis and the relationship between these symptom factors and FA values were then assessed with structural equation modelling, which included covariates such as age, sex, duration of illness and medications prescribed. RESULTS: Patients with schizophrenia had reduced FA in the genu of corpus callosum (gCC) compared to HC. A three-factor model, namely Positive, Negative, Disorganised factors, was determined as the best fit for the data. All three psychopathology factors were associated with decreased FA in the gCC and bilateral cingulate gyrus. Higher Negative factor scores were uniquely associated with decreased FA in the right sagittal striatum and right superior longitudinal fasciculus. CONCLUSIONS: This study found shared and specific WM changes and their associations with specific symptom clusters, which potentially allows for monitoring of such white matter findings associated with clinical presentations in schizophrenia over treatment and illness course.

Evaluating the feasibility and acceptability of self-injection of subcutaneous depot medroxyprogesterone acetate (DMPA) in Senegal: a prospective cohort study.

OBJECTIVES: Expanding contraceptive options through self-injection may improve access and confidentiality. There are few published studies on contraceptive self-injection in sub-Saharan Africa and none in West Africa, a region with high unmet need. This study was performed to assess feasibility of subcutaneous DMPA self-injection in Senegal; objectives were to (1) measure the proportion of participants who self-injected competently 3 months after training, (2) measure the proportion who self-injected on time (defined conservatively as within 7 days of reinjection date), and (3) assess acceptability of self-injection. STUDY DESIGN: In this prospective cohort study, 378 women aged 18-49 years were trained to self-inject by study nurses. Three months later, women returned unprompted to the clinic to self-inject, and technique and visit timing were evaluated. Women continuing with a third self-injection were followed up at home after their next scheduled injection date. At each interaction, participants were interviewed to learn about their experience; additional questions during the final home visit focused on storage and disposal practices, and acceptability. RESULTS: Among the 337 participants followed up 3 months post-training, 310 self-injected, and 87% did so competently. Factoring in women who declined to self-inject, electing to have the provider administer the injection instead, a total of 80% [95% confidence interval (CI)=75-84%] self-injected competently 3 months post-training, and 84% [95% CI=80-88%] reinjected on time, while 72% [95% CI=67-77%] were both on time and competent. The vast majority (93%) expressed a desire to continue. CONCLUSIONS: Self-injection is feasible and acceptable among most study participants in Senegal. IMPLICATIONS: These first research results on contraceptive self-injection in West Africa indicate initial feasibility and acceptability of the practice. Results underscore the importance of designing self-injection programs that empower and support women, including those with limited education.

Acceptability of Contraceptive Self-Injection with DMPA-SC Among Adolescents in Gulu District, Uganda.

CONTEXT: In Uganda, an estimated one in four adolescent women have begun childbearing. Many adolescent pregnancies are unintended because of substantial barriers to contraceptive access. The injectable contraceptive is the most commonly used method in Uganda, and a new subcutaneous version offers the possibility of reducing access barriers by offering a self-injection option. However, more information about adolescent attitudes toward and interest in self-injection is needed. METHODS: In 2015, in-depth interviews were conducted with a purposive sample of 46 adolescent women aged 15-19 from rural and urban areas of Gulu District. Respondents were asked about their demographic characteristics, experience with contraceptives and opinions about injectable contraception, then introduced to subcutaneous depot medroxyprogesterone acetate (DMPA-SC) and trained in how to give an injection using a model. They were then asked their opinion about contraceptive self-injection. The interviews were transcribed and analyzed qualitatively to identify key themes. RESULTS: Although the injectable was generally viewed favorably, some adolescents expressed reservations about the suitability of injectable contraception for adolescents. The most common concern was fear of infertility. The majority felt self-injection would be an appealing option to adolescents because of the time and money saved and the discreet nature of injecting at home. Barriers to self-injection included fear of needles, the potential of making a mistake and lack of privacy at home. CONCLUSIONS: Contraceptive self-injection has the potential to increase contraceptive access and use for adolescents in Uganda, and should be considered as a delivery modality in the context of adolescent-friendly contraceptive services.

A prospective cohort study of the feasibility and acceptability of depot medroxyprogesterone acetate administered subcutaneously through self-injection.

OBJECTIVES: Evidence on contraceptive self-injection from the United States and similar settings is promising, and the practice may increase access. There are no published studies on the feasibility of contraceptive self-injection in sub-Saharan Africa to date. The purpose of this study was to assess feasibility of subcutaneous depot medroxyprogesterone acetate self-injection in Uganda, with specific objectives to (a) measure the proportion of participants who self-injected competently, (b) measure the proportion who self-injected on time 3 months after training (defined conservatively as within 7 days of their reinjection date) and (c) assess acceptability. STUDY DESIGN: In this prospective cohort study, 380 18-45-year-old participants completed self-injection training by licensed study nurses, guided by a client instruction booklet, and practiced injection on prosthetics until achieving competence. Nurses supervised participants' self-injection and evaluated injection technique using an observation checklist. Those judged competent were given a Sayana® Press unit, instruction booklet and reinjection calendar for self-injection at home 3 months later. Participants completed an interview before and after self-injection. Nurses visited participants at home following reinjection dates; during the follow-up visit, participants demonstrated self-injection on a prosthetic, injection technique was reevaluated, and a postreinjection interview was completed. RESULTS: Of 368 participants followed up 3 months posttraining, 88% [95% confidence interval (CI)=84-91] demonstrated injection competence, and 95% (95% CI=92-97) reinjected on time, while 87% (95% CI=84-90) were both on time and competent. Nearly all (98%) expressed a desire to continue. CONCLUSIONS: Self-injection is feasible and highly acceptable among most study participants in Uganda. IMPLICATIONS: The first research results on contraceptive self-injection in sub-Saharan Africa indicate initial feasibility and acceptability of the practice 3 months after women received one-on-one training and a highly visual training and memory aid. Results can inform self-injection programs which aim to increase women's autonomy and access to injectable contraception.

Mechanisms of anguilliform locomotion in fishes studied using simple three-dimensional physical models.

Physical models enable researchers to systematically examine complex and dynamic mechanisms of underwater locomotion in ways that would be challenging with freely swimming animals. Previous research on undulatory locomotion, for example, has used rectangular flexible panels that are effectively two-dimensional as proxies for the propulsive surfaces of swimming fishes, but these bear little resemblance to the bodies of elongate eel-like swimming animals. In this paper we use a polyurethane rod (round cross-section) and bar (square cross-section) to represent the body of a swimming Pacific hagfish (Eptatretus stoutii). We actuated the rod and bar in both heave and pitch using a mechanical controller to generate a propulsive wave at frequencies between 0.5 and 2.5 Hz. We present data on (1) how kinematic swimming patterns change with driving frequency in these elongate fish-like models, (2) the thrust-generating capability of these simple models, (3) how forces and work done during propulsion compare between cross-sectional shapes, (4) the wake flow patterns in these swimming models using particle image velocimetry. We also contrast kinematic and hydrodynamic patterns produced by bar and rod models to comparable new experimental data on kinematics and wake flow patterns from freely swimming hagfish. Increasing the driving frequency of bar and rod models reduced trailing edge amplitude and wavelength, and above 2 Hz a nodal point appeared in the kinematic wave. Above 1 Hz, both the rod and bar generated net thrust, with the work per cycle reaching a minimum at 1.5 Hz, and the bar always requiring more work per cycle than the rod. Wake flow patterns generated by the swimming rod and bar included clearly visible lateral jets, but not the caudolaterally directed flows seen in the wakes from freely swimming hagfish.

Baseline social amotivation predicts 1-year functioning in UHR subjects: A validation and prospective investigation.

Social amotivation and diminished expression have been reported to underlie negative symptomatology in schizophrenia. In the current study we sought to establish and validate these negative symptom domains in a large cohort of schizophrenia subjects (n=887) and individuals who are deemed to be Ultra-High Risk (UHR) for psychosis. Confirmatory factor analysis conducted on PANSS item domains demonstrate that the dual negative symptom domains exist in schizophrenia and UHR subjects. We further sought to examine if these negative symptom domains were associated with functioning in UHR subjects. Linear regression analyses confirmed that social amotivation predicted functioning in UHR subjects prospectively at 1 year follow up. Results suggest that the association between social amotivation and functioning is generalisable beyond schizophrenia populations to those who are at-risk of developing psychosis. Social amotivation may be an important dimensional clinical construct to be studied across a range of psychiatric conditions.

HIV self-testing could "revolutionize testing in South Africa, but it has got to be done properly": perceptions of key stakeholders.

South Africa bears the world's largest burden of HIV with over 6.4 million people living with the virus. The South African government's response to HIV has yielded remarkable results in recent years; over 13 million South Africans tested in a 2012 campaign and over 2 million people are on antiretroviral treatment. However, with an HIV & AIDS and STI National Strategic Plan aiming to get 80 percent of the population to know their HIV status by 2016, activists and public health policy makers argue that non-invasive HIV self-testing should be incorporated into the country HIV Counseling and Testing [HCT] portfolios. In-depth qualitative interviews (N = 12) with key stakeholders were conducted from June to July 2013 in South Africa. These included two government officials, four non-governmental stakeholders, two donors, three academic researchers, and one international stakeholder. All stakeholders were involved in HIV prevention and treatment and influenced HCT policy and research in South Africa and beyond. The interviews explored: interest in HIV self-testing; potential distribution channels for HIV self-tests to target groups; perception of requirements for diagnostic technologies that would be most amenable to HIV self-testing and opinions on barriers and opportunities for HIV-linkage to care after receiving positive test results. While there is currently no HIV self-testing policy in South Africa, and several barriers exist, participants in the study expressed enthusiasm and willingness for scale-up and urgent need for further research, planning, establishment of HIV Self-testing policy and programming to complement existing facility-based and community-based HIV testing systems. Introduction of HIV self-testing could have far-reaching positive effects on holistic HIV testing uptake, giving people autonomy to decide which approach they want to use for HIV testing, early diagnosis, treatment and care for HIV particularly among hard-to reach groups, including men.

Impact of psychiatric comorbidity in individuals at Ultra High Risk of psychosis - Findings from the Longitudinal Youth at Risk Study (LYRIKS).

Recent studies have reported a high prevalence of psychiatric comorbidities in Ultra High Risk (UHR) for psychosis populations. This study examined the prevalence of comorbidity and its impact on symptoms, functioning, cognition and transition to psychosis in the Longitudinal Youth at Risk Study (LYRIKS) sample. The Comprehensive Assessment of At-Risk Mental State (CAARMS) was used to identify UHR individuals and 163 participants were included in the study. Comorbid disorders were identified using the Structured Clinical Interview for DSM-IV-TR Axis I Disorders. Participants were evaluated on the CAARMS, Positive and Negative Syndrome Scale, Calgary Depression Scale for Schizophrenia, Beck Anxiety Inventory, Global Assessment of Functioning and Brief Assessment of Cognition in Schizophrenia. Clinical, functioning and cognitive characteristics by lifetime and current comorbidity groups were compared using multivariate tests. Independent predictors of comorbidity were identified through logistic regression. Chi-squared tests were used to compare comorbidity rates between those who had developed psychosis at one year and those who had not. We found that 131 UHR participants (80.4%) had a lifetime comorbidity while 82 (50.3%) had a current comorbidity with depressive disorders being the most common. UHR individuals with comorbidity had more severe symptoms, higher distress and lower functioning with no differences in general cognition. Lower functioning was associated with current comorbidity. Eleven participants (6.7%) had developed psychosis after one year and there were no differences in the comorbidity rates between those who developed psychosis and those who did not. Psychiatric comorbidities in the UHR group are associated with adverse clinical outcomes and warrant closer attention.

What are the constraints and opportunities for HIVST scale-up in Africa? Evidence from Kenya, Malawi and South Africa.

INTRODUCTION: HIV self-testing (HIVST) has the potential to increase uptake of HIV testing among untested populations in sub-Saharan Africa and is on the brink of scale-up. However, it is unclear to what extent HIVST would be supported by stakeholders, what policy frameworks are in place and how variations between contexts might influence country-preparedness for scale-up. This qualitative study assessed the perceptions of HIVST among stakeholders in three sub-Saharan countries. METHODS: Fifty-four key informant interviews were conducted in Kenya (n=16), Malawi (n=26) and South Africa (n=12) with government policy makers, academics, activists, donors, procurement specialists, laboratory practitioners and health providers. A thematic analysis was conducted in each country and a common coding framework allowed for inter-country analysis to identify common and divergent themes across contexts. RESULTS: Respondents welcomed the idea of an accurate, easy-to-use, rapid HIV self-test which could increase testing across all populations. High-risk groups, such as men, Men who have sex with men (MSM), couples and young people in particular, could be targeted through a range of health facility and community-based distribution points. HIVST is already endorsed in Kenya, and political support for scale-up exists in South Africa and Malawi. However, several caveats remain. Further research, policy and ensuing guidelines should consider how to regulate, market and distribute HIVST, ensure quality assurance of tests and human rights, and critically, link testing to appropriate support and treatment services. Low literacy levels in some target groups would also need context-specific consideration before scale up. World Health Organization (WHO) policy and regulatory frameworks are needed to guide the process in those areas which are new or specific to self-testing. CONCLUSIONS: Stakeholders in three HIV endemic sub-Saharan countries felt that HIVST will be an important complement to existing community and facility-based testing approaches if accompanied by the same essential components of any HIV testing service, including access to accurate information and linkages to care. While there is an increasingly positive global policy environment regarding HIVST, several implementation and social challenges limit scale-up. There is a need for further research to provide contextual and operational evidence that addresses concerns and contributes to normative WHO guidance.

Performance of Cervical Cancer Screening Techniques in HIV-Infected Women in Uganda.

OBJECTIVE: Women infected with human immunodeficiency virus (HIV) have a higher risk of HPV infections and developing cervical cancer, thus screening them is imperative. This study was aimed to evaluate and compare the performance of 3 cervical cancer screening options among HIV-infected women in Uganda. MATERIALS AND METHODS: Data from 2,337 Ugandan women who reported their HIV status were obtained from a population-based cervical cancer screening study. Women were offered 3 screening tests: vaginal and cervical careHPV and visual inspection with acetic acid (VIA), and the results were evaluated by HIV status. RESULTS: The prevalence of HIV infection was 16.5%. Women infected with HIV had a higher prevalence of cervical intraepithelial neoplasia grade 2+ (CIN2+) than uninfected women (12.9% vs 1.7%; p < .001). The sensitivity for cervical careHPV among the HIV-infected women was 94.3% compared to 81.3% among the uninfected women. Whereas the sensitivity for vaginal careHPV was also higher among the HIV-infected women, the sensitivity of VIA was higher among the uninfected women. The mean vaginal and cervical careHPV signal strength was higher in the HIV-infected women than in the uninfected women (p < .001). CONCLUSIONS: CareHPV is very sensitive for detecting CIN2+ in HIV-infected women, even using a vaginal sample. The sensitivity of careHPV in HIV-infected women is higher than in HIV-uninfected women. However, additional research is needed to determine the best option for screening and triage of HPV-positive women that can be implemented in low-resource settings, especially among HIV- and HPV-positive women.

What should the ideal HIV self-test look like? A usability study of test prototypes in unsupervised HIV self-testing in Kenya, Malawi, and South Africa.

HIV self-testing (HIVST) is increasingly being sought and offered globally, yet there is limited information about the test features that will be required for an HIV self-test to be easy to use, acceptable to users, and feasible for manufacturers to produce. We conducted formative usability research with participants who were naïve to HIVST using five prototypes in Kenya, Malawi, and South Africa. The tests selected ranged from early-stage prototypes to commercially ready products and had a diverse set of features. A total of 150 lay users were video-recorded conducting unsupervised self-testing and interviewed to understand their opinions of the test. Participants did not receive a test result, but interpreted standardized result panels. This study demonstrated that users will refer to the instructions included with the test, but these can be confusing or difficult to follow. Errors were common, with less than 25% of participants conducting all steps correctly and 47.3% of participants performing multiple errors, particularly in sample collection and transfer. Participants also had difficulty interpreting results. To overcome these issues, the ideal HIV self-test requires pictorial instructions that are easy to understand, simple sample collection with integrated test components, fewer steps, and results that are easy to interpret.
