Sexual minority men are at increased risk for anal squamous cell carcinoma. Our objective was to compare screening engagement among individuals randomized to self‐collect an anal canal specimen at home or to attend a clinic appointment. Specimen adequacy was then assessed for human papillomavirus (HPV) DNA genotyping. A randomized trial recruited cisgendered sexual minority men and transgender people in the community and assigned them to use a home‐based self‐collection swabbing kit or attend a clinic‐based swabbing. Swabs were sent for HPV genotyping. The proportions of participants completing screening in each study arm and the adequacy of their specimens for HPV genotyping were assessed. Relative risks were estimated for factors associated with screening. A total of 240 individuals were randomized. Age (median, 46 years) and HIV status (27.1% living with HIV) did not differ by study arm. A total of 89.2% and 74.2% of home‐arm and clinic‐arm individuals returned the swab, respectively (P =.003), difference between groups, 15.0% (95% CI 5.4%‐24.6%). Among black individuals, 96.2% and 63.2% in the home and clinic arms screened (P =.006). Among individuals with HIV, 89.5% and 51.9% in the home and clinic arms screened (P <.001). Self‐collected swabs and clinician‐collected swabs were comparable in adequacy for HPV genotyping (96.3% and 93.3%, respectively). People at highest risk for anal cancer may be more likely to screen if they are able to self‐collect swabs at home rather than attend a clinic. [ABSTRACT FROM AUTHOR]

Background: HCV self-testing (HCVST) may be an effective strategy to address low rates of HCV test uptake among men who have sex with men (MSM). We evaluated the effectiveness and cost of providing HCVST to increase HCV test uptake among MSM in China. Methods: Two parallel, unmasked, individual-level randomized controlled trials were conducted. HIV-negative MSM and MSM living with HIV were enrolled from 22 cities in China. Men in both trials were randomly assigned (1:1) into standard-of-care (SOC) or HCVST arms. The primary outcome was the proportion of participants who tested for HCV during the trial period. Intervention effects were estimated using multiply imputed data in the main analysis. Costs were measured using a micro-costing approach. Results: A total of 84 men who were HIV-negative (trial 1) and 84 men living with HIV were enrolled (trial 2). Overall, the proportion of individuals who underwent HCV testing during the trial period was higher in the HCVST arm compared to SOC in trial 1 (estimated risk difference (RD): 71.1%, 95% CI: 54.6 to 87.7%) and trial 2 (estimated RD: 62.9%, 95% CI: 45.7 to 80.1%). Over half (58.6%, 34/58) of HCV self-testers reported the self-test was their first HCV test. The cost per person tested in trial 1 was $654.52 for SOC and $49.83 for HCVST, and in trial 2 was $438.67 for SOC and $53.33 for HCVST. Conclusions: Compared to the standard of care, providing HCVST significantly increased the proportion of MSM testing for HCV in China, and was cheaper per person tested.

We present experiences of transgender women (TW) who have sex with men with SMARTtest, a smartphone app to accompany the INSTI Multiplex®, a one-minute, dual blood-based HIV/syphilis rapid test. TW participants (N = 11) received 10 INSTI Multiplex® tests to take home for self- and/or partner-testing and installed the SMARTtest app on their phones. The SMARTtest app aimed to support INSTI Multiplex users in correctly performing the test, interpreting the results, and connecting with care following a positive HIV or syphilis screening. After 3 months, users completed in-depth interviews on their experiences. A total of 9 TW used SMARTtest with partners. App feedback was positive, but refining is necessary. Specifically, TW reported that SMARTtest is easy to use and convenient; instructions on how to use the INSTI Multiplex presented on the app were helpful to complete procedures correctly; the most frequently used feature on SMARTtest was the information on clinics that offered confirmatory testing; and participants and their partners were not concerned about app privacy but reported that this could change if INSTI Multiplex detected an HIV-positive result. Further, participants provided recommendations on how to improve SMARTtest, and changes were mostly related to features, content, functionality, navigation, and overall "look" of the app. SMARTtest is promising to facilitate INSTI Multiplex® use in TW. User feedback should be integrated in future versions. [ABSTRACT FROM AUTHOR]

Background: Self-testing has been promoted as a means of increasing COVID-19 test coverage. In Belgium, self-testing was recommended as a complement to the formal, provider-administered indications, such as out of courtesy before meeting others and when feared to be infected. More than a year after the introduction of self-testing their place in the test strategy was evaluated. Methods: We assessed trends in the number of self-tests sold, the number of positive self-tests reported, the proportion sold self-tests/total tests, and the proportion of all positive tests that were confirmed self-tests. To evaluate the reason why people use self-tests, we used the results of two online surveys among members of the general population: one among 27,397 people, held in April 2021, and one among 22,354 people, held in December 2021. Results: The use of self-tests became substantial from end 2021 onwards. In the period mid-November 2021 – end-of-June 2022, the average proportion of reported sold self-tests to all COVID-19 tests was 37% and 14% of all positive tests were positive self-tests. In both surveys, the main reported reasons for using a self-test were having symptoms (34% of users in April 2021 and 31% in December 2021) and after a risk contact (27% in both April and December). Moreover, the number of self-tests sold, and the number of positive self-tests reported closely followed the same trend as the provider-administered tests in symptomatic people and high risk-contacts, which reinforces the hypothesis that they were mainly used for these two indications. Conclusions: From end 2021 onwards, self-testing covered a significant part of COVID-19 testing in Belgium, which increased without doubt the testing coverage. However, the available data seem to indicate that self-testing was mostly used for indications outside of official recommendations. If and how this affected the control of the epidemic remains unknown. [ABSTRACT FROM AUTHOR]

Background: Adolescent girls and young women (AGYW) account for 29% of new HIV infections in Uganda despite representing just 10% of the population. Peer support improves AGYW linkage to HIV care and medication adherence. We evaluated the feasibility and acceptability of peer delivered HIV self-tests (HIVST) and oral pre-exposure prophylaxis (PrEP) to young women in Uganda. Methods: Between March and September 2021, we conducted a pilot study of 30 randomly selected young women, aged 18–24 years, who had received oral PrEP for at least three months, but had suboptimal adherence as measured by urine tenofovir testing (< 1500 ng/ml). Participants were offered daily oral PrEP and attended clinic visits three and six months after enrollment. Between clinic visits, participants were visited monthly by trained peers who delivered HIVST and PrEP. Feasibility and acceptability of peer-delivered PrEP and HIVST (intervention) were measured by comparing actual versus planned intervention delivery and product use. We conducted two focus groups with young women, and five in-depth interviews with peers and health workers to explore their experiences with intervention delivery. Qualitative data were analyzed using thematic analysis. Results: At baseline, all 30 enrolled young women (median age 20 years) accepted peer-delivered PrEP and HIVST. Peer delivery visit completion was 97% (29/30) and 93% (28/30) at three and six months, respectively. The proportion of participants with detectable tenofovir in urine was 93% (27/29) and 57% (16/28) at months three and six, respectively. Four broad themes emerged from the qualitative data: (1) Positive experiences of peer delivered HIVST and PrEP; (2) The motivating effect of peer support; (3) Perceptions of female controlled HIVST and PrEP; and (4) Multi-level barriers to HIVST and PrEP use. Overall, peer delivery motivated young women to use HIVST and PrEP and encouraged persistence on PrEP by providing non-judgmental client-friendly services and adherence support. Conclusion: Peer delivery of HIVST and oral PrEP was feasible and acceptable to this sample of young women with suboptimal PrEP adherence in Uganda. Future larger controlled studies should evaluate its effectiveness among African AGWY. [ABSTRACT FROM AUTHOR]

Secondary distribution of HIV self-test is promising to increase testing uptake while the facilitators and barriers of secondary distribution remain unclear. In-depth interviews were conducted with 22 MSM who had participated in secondary distribution of HIVST in southern China. Data were thematically analyzed to capture participants' motivations, procedures, and challenges when accessing and distributing self-tests. MSM in China are willing to distribute HIVST to members in their social network, but their decision-making is impacted by their ability to broach sexual health conversations, evaluations of the recipients, and perceived trustworthiness of the self-test. Our study suggested that several strategies, including creating a friendly environment for sexual health conversations and establishing nationwide policies related to quality assured self-tests and standardized self-testing protocols, may be helpful to advance this approach in China.

Introduction. The National Cervical Screening Programme (NCSP) will switch from cervical cytology to Human Papillomavirus (HPV) testing as the primary cervical screening modality in 2023. To prepare for rollout an implementation study of HPV testing in primary care commenced in August 2022 in three different geographic regions in NZ. Aims. This study explores Primary Care Staff's experience of using the HPV testing pathway in the 'Let's test for HPV' study so that recommendations can be made to improve the testing process before nationwide roll-out. Method. Thirty-nine primary care staff were interviewed across all 17 practices in the Capital and Coast, Canterbury and Whanganui region participating in the 'Let's Test For HPV' study. In total 19 interviews took place which followed a semi-structured approach. These interviews were recorded and transcribed. Template analysis was carried out on transcripts to aid in identifying themes. Results. Three key themes, with additional subthemes, were identified. Staff were strongly supportive of the new testing regime. Interviewees identified some issues with the new pathway. Educational needs for both patients and clinicians were identified. Conclusion. Primary care staff described the experience of using the HPV testing pathway positively; however, there were requests for ongoing additional support and nationwide rollout to be supported by practitioner and patient education programmes. With the right support this new pathway for cervical cancer screening has the potential to improve access for previously underserved and unserved groups. [ABSTRACT FROM AUTHOR]

IntroductionHIV self-testing (HIVST) in outpatient departments (OPD) is a promising strategy for HIV testing in Malawi, given high OPD patient volumes and substantial wait times. To evaluate the relative cost and expected impact of facility-based HIVST (FB-HIVST) at OPDs in Malawi for increasing HIV status awareness, we conducted an economic evaluation of an HIVST cluster-randomized controlled trial.MethodsA cluster-randomized trial was conducted at 15 sites in Malawi from September 2017 to February 2018 with three arms: 1) Standard provider-initiated-testing-and-counselling (PITC); 2) Optimized PITC (additional provider training and job-aids) and 3) FB-HIVST (HIVST demonstration, distribution and kit use in OPD, private kit interpretation and optional HIV counselling). The total production cost per newly identified positive and per person newly initiated on ART were calculated by study arm. These were calculated as the total cost of testing everyone divided by the number of newly identified positives; and the total cost of testing everyone divided by the number of those initiated on ART. Cost-outcomes were calculated under three cost scenarios: (1) full study costs, (2) routine implementation costs and (3) routine implementation + reduced cost for HIVST kits.ResultsThe average cost per person newly diagnosed in the full study cost scenario was $101, $156 and $189, and cost per person initiated on ART was $121, $156 and $279 for Standard PITC, Optimized PITC and FB-HIVST respectively. In the routine implementation cost scenario, the average cost per person newly diagnosed was reduced to $83, and $93, and cost per person initiated on ART to $83, and $137 for Optimized PITC and FB-HIVST respectively. In the negotiated HIVST cost scenario, the average cost per person newly diagnosed was reduced to $55 and cost per person newly initiated on ART reduced to $81 in the FB-HIVST arm.ConclusionsWhile the cost per new ART initiation through FB-HIVST was higher than Standard PITC, FB-HIVST could become cost-saving compared to PITC if the cost of kits is reduced or if treatment linkage rate were increased in the FB-HIVST arm. For high volume OPDs, HIVST may increase facility capacity and increase the number of newly diagnosed positives.

ObjectivesTo evaluate experiences and reactions after receiving a mailed, unsolicited human papillomavirus self-sampling kit and identify psychosocial correlates of using kits.MethodsSurvey participants were underscreened women aged 30-64 who were mailed human papillomavirus kits as part of a pragmatic trial at Kaiser Permanente Washington, a United States integrated health care system. Six months after the mailing, we invited kit returners and non-returners to complete a web survey that measured psychosocial factors (e.g. cervical cancer/human papillomavirus knowledge, attitudes toward screening), experiences, and reactions to kits. We compared responses between kit returners and non-returners.ResultsComparing 116 kit returners (272 invited) and 119 non-returners (1083 invited), we found no clinically significant differences in psychosocial factors. Overall, survey respondents showed knowledge gaps in human papillomavirus natural history (82% did not know human papillomavirus infection can clear on its own) and interpreting human papillomavirus test results (37% did not know a human papillomavirus-negative result indicates low cancer risk). Kit returners found kits convenient and easy to use (>90%). The most common reason for non-return was low confidence in ability to correctly use a kit, although many non-returners (49%) indicated that they would consider future use. Women reported low trust in human papillomavirus testing to identify women at high risk for cervical cancer (52% in returners, 42% in non-returners).ConclusionsScreening programs could improve uptake and acceptability of human papillomavirus self-sampling through outreach materials that emphasize the high efficacy of human papillomavirus testing for cervical cancer screening and educate patients about how to interpret results.

Background Self-monitoring of blood pressure (SMBP) improves blood pressure (BP) outcomes at 12-months, but information is lacking on how SMBP affects hypertension care processes and longer-term BP outcomes. Methods and Results We pooled individual participant data from 4 randomized clinical trials of SMBP in the United Kingdom (combined n=2590) with varying intensities of support. Multivariable random effects regression was used to estimate the probability of antihypertensive intensification at 12 months for usual care versus SMBP. Using these data, we simulated 5-year BP control rates using a validated mathematical model. Trial participants were mostly older adults (mean age 66.6 years, SD 9.5), male (53.9%), and predominantly white (95.6%); mean baseline BP was 151.8/85.0 mm Hg. Compared with usual care, the likelihood of antihypertensive intensification increased with both SMBP with feedback to patient or provider alone (odds ratio 1.8, 95% CI 1.2-2.6) and with telemonitoring or self-management (3.3, 2.5-4.2). Over 5 years, we estimated 33.4% BP control (

Abstract Background In 2020, almost 20% of people living with HIV (PLHIV) in Morocco are still unaware of their HIV status. Under these circumstances, HIV self-test (HIVST) can be an efficient additional tool for improving the testing rates in Morocco and reaching the first objective of the UNAIDS 95–95-95 goal. ALCS, a Community-based organization, involved in HIV Testing since 1992, and the Ministry of Health of Morocco conducted, a study on the acceptability and usability of HIVST among Female sex workers (FSW) and MSM (men who have sex with men), using a salivary rapid test. To our knowledge, this is the first study in Morocco exploring these parameters. Methods We conducted a pilot study on the usability of the OraQuick HIV-1/2 salivary self-test among MSM and FSW visiting the ALCS centers for standard HIV rapid testing in five Moroccan cities. Participants chose whether or not to be assisted by lay provider HIV testing. The counselors sampled them to perform a standard rapid test and then invited them to a private room to perform the HIV self-test simultaneously. In addition, a questionnaire was administered to collect socio-demographic data and to assess their opinion about the usability of the salivary HIVST. Results Our study was carried out for 5 months and included 492 participants (257 MSM and 233 FSW). The average age of the participants was 29 years among MSM vs 34 years among FSW. The FSW have a lower educational level, 28,8% of them are Illiterate vs. 6,1% of the MSM. Only 18% of participants were aware of the existence of the HIVST, nevertheless, we recorded a very high rate of acceptability (90,6%) of the HIVST. Performing the HIVST was deemed very easy for 92,2% of MSM versus 80,6% of FSW. Although it was found very difficult for six participants, including five FSW, 4 of them could not read or write. Overall, the study registered a high HIV positivity rate (3,8%) and 100% of concordance between HIVST participants’ interpretation and standard HIV testing performed by ALCS lay provider HIV testing. Conclusion Our study shows very high acceptability of HIVST among FSWs and MSM in Morocco, HIV self-testing is still unknown by key populations in Morocco, and the low level of education of FSWs may be a barrier to the use of this test, but with the proposed assistance and adapted demonstration tools, the HIV self-testing will certainly improve access to testing in Morocco.

Abstract Background Adolescent girls and young women (AGYW) at institutions of higher learning are at high risk of HIV, and conventional HIV testing services may not reach them sufficiently. HIV self-testing (HIVST) scalability can be informed by identifying AGYW who have used or are interested in using HIVST. We aimed to determine factors associated with use and willingness to use HIVST among female university students. Methods An online cross-sectional survey was conducted among 483 female students at Makerere University, Uganda. Proportions of students who have used or are willing to use HIVST and their associated factors were determined. Modified Poisson regression models were used to estimate prevalence ratios (PR) and their 95% confidence intervals (CI). Results The median age of the participants was 22 (Interquartile range [IQR] 21–23) years, and 21% had never tested for HIV. Over 93% were willing to utilize HIVST, and 19% had ever used HIV self-test kits. Increasing age (adjusted prevalence ratio [aPR] 1.23 per year, 95% CI 1.07–1.43) was significantly associated with HIVST use. Predictors of willingness to self-test for HIV were college type (arts vs. science-based, aPR 0.92, 95% CI 0.88–0.97), number of sexual partners (one, aPR 1.07, 95% CI 1.03–1.12 or ≥ 2, aPR 1.08, 95% CI 1.04–1.19, vs. none), alcohol (aPR 1.04, 95% CI: 1.00–1.09) or injection drug (aPR 1.04, 95% CI 1.00–1.09) use, a history of sexually transmitted infections in past 12 months (aPR 1.05, 95% CI 1.01–1.09), and HIV testing experience (tested in past 12 months, aPR 1.12, 95% CI 1.02–1.22 or over 12 months, aPR 1.13, 95% CI 1.03–1.24, vs. never tested). Conclusion HIVST was highly acceptable despite its limited use. This study demonstrates female student characteristics that can be leveraged to scale up HIVST programs in higher institutions of learning.

Abstract Background People who inject drugs (PWID) are disproportionally affected by hepatitis C virus (HCV) infection and many remain undiagnosed. HCV self-testing (HCVST) may be an effective approach to increase testing uptake, but has rarely been used among PWID. We assessed the usability and acceptability of HCVST among PWID in Kenya. Methods We conducted a cross-sectional study nested within a cohort study between August and December 2020 on Kenya’s North Coast region. Participants were handed a prototype oral fluid HCVST kit and asked to conduct the test relying on the instructions for use. Usability was assessed by documenting errors made and difficulties faced by participants. Acceptability was assessed using an interviewer-administered semi-structured questionnaire. Results Among 150 participants, 19% were female and 65.3% had primary level education or lower. 71.3% made at least one error, 56.7% experienced some difficulty during at least one step, and the majority of participants (78%) required assistance during at least one step of the procedure. Most common errors occurred when placing the tube into the stand (18%), collecting the oral fluid sample (24%) and timing of reading results (53%). There was a strong association between presence of symptoms of opiate withdrawals and observed errors (94% vs 62%; p = 0.016) in a sub-group of 74 participants assessed. Inter-reader and inter-operator concordance were 97.7% (kappa: 0.92) and 99.2% (kappa: 0.95), respectively. Acceptability assessed by asking whether participants would choose to use HCVST prior to and after conducting HCVST was 98% and 95%, respectively. Conclusions We found a high acceptability of oral fluid HCVST among PWID. User errors were common and were associated with the presence of withdrawal symptoms among users. Despite errors, most participants were able to obtain and interpret results correctly. These findings suggest that this group of users may benefit from greater messaging and education including options to receive direct assistance when self-testing for HCV.

Abstract Background Brazil is among the countries in South America where the COVID-19 pandemic has hit the general population hardest. Self-testing for SARS-CoV-2 infection is one of the community-based strategies that could help asymptomatic individuals at-risk of COVID-19, as well as those living in areas that are difficult for health personnel to reach, to know their infectious status and contribute to impeding further transmission of the virus. Methods A population-based survey was conducted in November 2021, to assess the acceptability of rapid SARS-CoV-2 antigen self-testing among the population of São Paulo. Survey respondents were approached at more than 400 different street-points that were randomly selected using a five-stage randomization process. A 35-item structured questionnaire was used. Dependent variables for our analyses were the likelihood to use and willingness to pay for self-testing, and the likelihood of taking preventive measures to prevent onward transmission of SARS-CoV-2 following a reactive self-test result. Bivariate and multivariate regression analyses were performed. Results Overall, 417 respondents (44.12% female) participated; 19.66% had previously had COVID-19 disease. A minority (9.59%) felt at high-risk of COVID-19. The majority of both females and males (73.91% and 60.09%, respectively) were in favor of the idea of SARS-CoV-2 self-testing. Overall, if self-tests were available, almost half of the sample would be very likely (n = 54, 12.95%) or likely (n = 151, 36.21%) to use one if they felt they needed to. Upon receiving a positive self-test result, the majority of respondents would communicate it (88.49%), request facility-based post-test counseling (98.32%), self-isolate (97.60%), and warn their close contacts (96.64%). Conclusion Rapid SARS-CoV-2 antigen self-testing could be an acceptable screening tool in São Paulo. The population would be empowered by having access to a technology that would allow them to test, even if asymptomatic, when traveling, or going to work or school. If there is a surge in the incidence of cases, self-testing could be a good approach for mass case detection by Brazil’s already overstretched Unified Health System.

Objectives: To determine the real‐world outcomes associated with using the GetaKit.ca website to distribute COVID self‐tests to persons with risk factors, with a focus on facilitating testing for persons who are Black, Indigenous, or of Colour (BIPOC). Methods: GetaKit was an open cohort observational study to distribute free self‐tests, starting with HIV self‐testings and then adding the Lucira Check‐It® COVID self‐test. Participants would register on our website and complete a risk assessment, which would calculate their need for each type of testing. Results: Focusing on the COVID self‐tests, from September to December 2021 (with targeted outreach in winter 2022), we distributed 6474 COVID self‐tests to 3653 persons through 4161 unique orders, of which 47% came from BIPOC participants. Compared to white participants, BIPOC participants were more likely to have been a contact of COVID but less likely to be vaccinated. As well, 69% of results were reported back via the GetaKit.ca website, with 5.3% of these being positive. The positivity rate for our 3653 participants was 9.6%. Conclusions: Delivering COVID self‐tests via our website provided tests to BIPOC communities and yielded positivity rates that matched local COVID testing centres. This highlights the utility of such systems for delivering testing during future pandemics. [ABSTRACT FROM AUTHOR]

Introduction: The United States Centers for Disease Control and Prevention currently recommends HIV screening at least annually among sexually active gay, bisexual and other men who have sex with men (MSM), but only half report being tested in the past year in the United States. As HIV self‐test kits are becoming more available around the United States via web and app‐based interventions, it is important to understand who is willing and able to order them. This analysis sought to better understand predictors of free HIV self‐test kit utilization among MSM in M‐cubed, an HIV prevention mobile app intervention trial in Atlanta, Detroit and New York City. Methods: We conducted an exploratory secondary analysis of self‐report and in‐app data collected from the intervention arm of the M‐Cubed study from 24 January 2018 to 31 October 2019. Behavioural, demographic and other potential predictors of HIV self‐test ordering were identified from Social Cognitive Theoretical underpinnings of the app, and from the literature. Significant predictor variables in bivariate analyses were considered for inclusion in the empiric multivariable model. Demographic variables chosen a priori were then added to a final model estimating adjusted prevalence ratios (aPR). Results: Over half of the 417 intervention participants ordered an HIV self‐test kit during the study. In bivariate analyses, ordering a kit was associated with HIV testing history, plans to get tested and reported likelihood of getting tested. In the final model, participants were more likely to order a kit if they reported plans to get tested in the next 3 months (aPR = 1.58, 95% CI: 1.18–2.11) or had not tested for HIV in the past 3 months (aPR = 1.38, 95% CI: 1.13–1.70). There was no difference in HIV self‐test kit ordering by income, race/ethnicity or age. Conclusions: HIV testing is an important tool in ending the HIV epidemic and must be accessible and frequent for key populations. This study demonstrates the effectiveness of HIV self‐test kits in reaching populations with suboptimal testing rates and shows that self‐testing may supplement community‐based and clinical testing while helping overcome some of the structural barriers that limit access to annual HIV prevention services for MSM.

Could home human immunodeficiency virus (HIV) self-testing make a major difference in identifying persons with undiagnosed HIV in the United States? We argue that approval of new self-test assays for home use would help but must be combined with extensive investment in community outreach and linkage to care to make an impact.

Purpose: We hypothesized that SARS-CoV-2 infection numbers reported by governmental institutions are underestimated due to high dark figures as only results from polymerase chain reaction (PCR) tests are incorporated in governmental statistics and testing capacities were further restricted as of July, 2022. Methods: A point prevalence investigation was piloted by rapid antigen testing (RAT) among participants of the VACCELERATE volunteer registry. 2400 volunteers were contacted, of which 500 received a RAT including instructions for self-testing in the first week of July, 2022. Results were self-reported via e-mail. Results: 419 valid RAT results were collected until July 7th, 2022. Between July-1 and July-7, 2022, 7/419 (1.67%) tests were positive. Compared to reports of the German Federal Government, our results suggest a more than twofold higher prevalence. Three out of seven positive individuals did not have a PCR test and are therefore likely not to be displayed in governmental statistics. Conclusion: Our findings imply that the actual prevalence of SARS-CoV-2 may be higher than detected by current surveillance systems, so that current pandemic surveillance and testing strategies may be adapted.

In Ontario, new HIV diagnoses continue to affect gay, bisexual, and other men who have sex with men (gbMSM) and persons of African, Caribbean, or Black (ACB) ethnicities. Because treatment and suppressed viral loads flow from diagnosis, testing is key. We sought to determine the outcomes of online ordering and mail‐out of free at‐home HIV self‐testing in Ontario, Canada. We implemented the GetaKit study to offer such free HIV self‐testing using the INSTI® test and offered it via a website (GetaKit.ca) to eligible persons in Ontario. From April 1, 2021 to January 31, 2022, we distributed kits to 1551 persons; 40% were white and 26% were ACB. We found that ACB participants were less likely to fulfill established criteria for HIV PrEP, such as previous sexually transmitted infections diagnoses and drug use, despite having a similar test positivity rate. We also found that ACB women, who may represent a larger number of new infections than previously thought, did not have a higher rate of first‐time testing. Our results suggest that HIV self‐testing can enable testing, but that work is required to increase uptake among ACB persons and women. Overall, HIV self‐testing thus corresponded with increased testing among persons who were Black, yet lower rates of results reporting. Patient or Public Contributions: Community members from the AIDS Committee of Ottawa, Max Ottawa, and Black Cap, and nurses from Ottawa Public Health were involved in the design, promotion, and implementation of this study.

Few studies among gay, bisexual and other men who have sex with men (GBMSM) have examined facilitators and barriers to self-collecting specimens for extragenital STI screening, and none have evaluated attitudes towards self-collecting hair samples that can be utilized for PrEP drug level testing to assess adherence. To address this gap, we interviewed 25 sexually active GBMSM who were offered a choice to self-collect and return finger-stick blood samples (for actual HIV testing), pharyngeal swabs, rectal swabs and urine specimens (for actual gonorrhea and chlamydia testing), and hair samples (to visually determine their adequacy for PrEP drug level testing): 11 who returned all, 4 who returned some, and 10 who did not return any. Participants found self-collecting finger-stick blood samples and rectal swabs more challenging than other specimens. Frequently discussed facilitators of return included an opportunity to confirm one's HIV or STI status, limited access to a healthcare provider and a desire to advance research focusing on home-based testing. Commonly cited barriers to return included low self-efficacy pertaining to self-collection and apprehension around the possibility of delay or loss of specimens during transit. Offering additional support such as real-time video conferencing may prove helpful in future field-based research with GBMSM. [ABSTRACT FROM AUTHOR]

This prospective study aimed to evaluate the performance of the InstaView COVID-19 (coronavirus diseases 2019) Antigen Home Test (InstaView AHT) which detects severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antigens. In this test kit, surface-enhanced Raman spectroscopy was used, a stacking pad was inserted, and nasal swab and salivary swab samples were used simultaneously to improve performance. The clinical performance of the InstaView AHT was compared to that of RT-PCR using nasopharyngeal samples. The participants without any prior training were recruited and performed the sample collection, testing, and interpretation of the results by themselves. Of the 91 PCR-positive patients, 85 had positive InstaView AHT results. The sensitivity and specificity of the InstaView AHT were 93.4% (95% confidence interval [CI]: 86.2–97.5) and 99.4% (95% CI: 98.2–99.9). The sensitivity of the InstaView AHT was above 90% for all samples obtained from patients with Ct ≤ 20, 20 < Ct ≤ 25, and 25 < Ct ≤ 30 (100%, 95.1%, and 92.0%, respectively). The InstaView AHT can be used as an alternative to RT-PCR testing because of its relatively high sensitivity and specificity, especially when SARS-CoV-2 prevalence is high, and the availability of RT-PCR testing is limited.

Home-based couples HIV testing and counseling and HIV self-testing (HIVST) for pregnant women can promote HIV status disclosure and male partner testing; however, cost data are lacking. We examined a home-based couples intervention (HBCI) and HIVST intervention costs per couple (unit cost) during pregnancy and postpartum in Kenya. This randomized controlled trial is comparing HBCI and HIVST for couples among pregnant women attending antenatal care clinics in two counties in southwestern Kenya. We used micro-costing to estimate the unit cost per couple receiving the intervention as the total of direct and indirect costs for each study arm in 2019 US$. We used a one-month window to conduct a time and motion study to determine personnel effort and resources. We then compared the unit cost by arm, identified key cost drivers, and conducted sensitivity analyses for cost uncertainties. At base-case, the unit cost was $129.01 and $41.99, respectively, for HBCI and HIVST. Personnel comprised half of the unit cost for both arms. Staff spent more time on activities related to participant engagement in HBCI (accounting for 6.4% of the unit cost) than in HIVST (2.3%). Staff training was another key cost driver in HBCI (20.1% of the unit cost compared to 12.5% in HIVST). Sensitivity analyses revealed that the unit cost ranges were $104.64-$154.54 for HBCI and $30.49-$56.59 for HIVST. Our findings may guide spending decisions for future HIV prevention and treatment programs for pregnant couples in resource-limited settings such as Kenya. • Home-based couples human immunodeficiency virus (HIV) testing and counseling and HIV self-testing for pregnant couples can promote HIV status disclosure and male partner testing and improve maternal and child health; nevertheless, cost data are lacking. • In southwestern Kenya, the program implementation cost per couple was $129 for home-based couples HIV testing and counseling and $42 for HIV self-testing. • These findings may serve as important inputs for upcoming economic evaluation research and guide spending decisions for future HIV prevention and treatment programs for pregnant couples in resource-limited settings, such as Kenya.

Introduction: The decline in functional capacity (FC) interferes with the functional independence of older adults, so it is important to assess the FC and use appropriate instruments for this. Objective: To investigate the Glittre Activities of Daily Living (ADL) test’s validity and reliability for assessing functional capacity in older adults. Methods: Cross-sectional study with a sample of 100 elderly (68 ± 5.16 years). To assess the convergent validity, the Six-Minute Walk Test (6MWT) and the Timed Up and Go Test (TUG) were performed. The intra-examiner test-retest of the Glittre-ADL test was performed on the same day with a 30-minute interval between repetitions and inter-examiner reliability with an interval of seven days. Results: There was a strong correlation between the Glittre-ADL test and the 6MWT (r= -0.75; p

Self-testing is a promising approach to certifying quantum states or measurements. Originally, it relied solely on the outcome statistics of the measurements involved in a device-independent (DI) setup. Extra physical assumptions about the system make the setup semi-DI. In the latter approach, we consider a prepare-and-measure scenario in which the dimension of the mediating particle is assumed to be two. In a setup involving four (three) preparations and three (two) projective measurements in addition to the target, we exemplify how to self-test any four- (three-) outcome extremal positive operator-valued measure using a linear witness. One of our constructions also achieves self-testing of any number of states with the help of as many projective measurements as the dimensionality of the space spanned by the corresponding Bloch vectors. These constructions are conjectured to be minimal in terms of the number of preparations and measurements required. In addition, we implement one of our prepare-and-measure constructionson IBM and IonQ quantum processors and certify the existence of a complex qubit Hilbert space based on the data obtained from these experiments.

The human immunodeficiency virus (HIV) infection has been regarded as a global public health concern. In the global mission to minimize the existing gap on the diagnostic front, a number of strategies to promote HIV testing have been encouraged in heterogeneous settings. Detection of HIV infection using self-testing kits has emerged as an important approach to ascertain the identification of new cases and for connecting the affected people with the health-care delivery system. It is quite an alarming fact that despite HIV is a major public health problem in India, we to date have no policy on the promotion of self-testing. The findings of a recently released report in India revealed that self-testing was found to be acceptable to vulnerable population groups and their partners. To conclude, acknowledging the merits that have been linked with self-testing and considering the encouraging results obtained in Indian settings, it is the need of the hour that policymakers draft the much-awaited policy on the promotion of HIV self-testing in the nation and promote it.

At the end of 2021, with the rapid escalation of COVID19 cases due to the Omicron variant, testing centers in Canada were overwhelmed. To alleviate the pressure on the PCR testing capacity, many provinces implemented new strategies that promote self testing and adjust the eligibility for PCR tests, making the count of new cases underreported. We designed a novel compartmental model which captures the new testing guidelines, social behaviours, booster vaccines campaign and features of the newest variant Omicron. To better describe the testing eligibility, we considered the population divided into high risk and non-high-risk settings. The model is calibrated using data from January 1 to February 9, 2022, on cases and severe outcomes in Canada, the province of Ontario and City of Toronto. We conduct analyses on the impact of PCR testing capacity, self testing, different levels of reopening and vaccination coverage on cases and severe outcomes. Our results show that the total number of cases in Canada, Ontario and Toronto are 2.34 (95%CI: 1.22–3.38), 2.20 (95%CI: 1.15–3.72), and 1.97(95%CI: 1.13–3.41), times larger than reported cases, respectively. The current testing strategy is efficient if partial restrictions, such as limited capacity in public spaces, are implemented. Allowing more people to have access to PCR reduces the daily cases and severe outcomes; however, if PCR test capacity is insufficient, then it is important to promote self testing. Also, we found that reopening to a pre-pandemic level will lead to a resurgence of the infections, peaking in late March or April 2022. Vaccination and adherence to isolation protocols are important supports to the testing policies to mitigate any possible spread of the virus.

BackgroundThe World Health Organization recommends HIV self-testing (HIVST) as an additional approach to HIV testing services. We aimed to assess to what extent HIVST was conducted correctly by Chinese men who have sex with men (MSM) and to identify user errors during the HIVST process in order to inform strategies to optimize its use and thus reduce the number of undiagnosed HIV infections.MethodsBetween February and March 2017, participant observations were conducted with 27 MSM in an east coastal city in China. In the presence, but without the assistance or orientation, of a trained HIV testing counselor, participants conducted HIVST (either finger prick or oral fluid) according to manufacturers' instructions. Errors were recorded on checklists during direct observation and double checked afterwards by reviewing video files of the observations.ResultsOverall, 12 participants (44.4%) had invalid test results due to user errors. Just five (18.5%) did not make any errors during the entire HIVST process. Failure to follow all the steps based on manufactures' instructions was a common problem for both finger prick and oral fluid self-testers. For finger prick users, most errors occurred during the stage of collecting the specimen. In contrast, oral fluid users made most errors during the stage of testing the collected specimen.ConclusionsAlthough we found that user errors were common among MSM administering HIVST, this should not deter or discourage routine implementation and scale-up of HIVST as strategies can be implemented to facilitate the correct use of HIVST.Trial registrationThis study was a part of a clinical trial: ClinicalTrials.gov (# NCT02999243 ); Registration date: December 20, 2016.

Abstract Introduction The United States Centers for Disease Control and Prevention currently recommends HIV screening at least annually among sexually active gay, bisexual and other men who have sex with men (MSM), but only half report being tested in the past year in the United States. As HIV self‐test kits are becoming more available around the United States via web and app‐based interventions, it is important to understand who is willing and able to order them. This analysis sought to better understand predictors of free HIV self‐test kit utilization among MSM in M‐cubed, an HIV prevention mobile app intervention trial in Atlanta, Detroit and New York City. Methods We conducted an exploratory secondary analysis of self‐report and in‐app data collected from the intervention arm of the M‐Cubed study from 24 January 2018 to 31 October 2019. Behavioural, demographic and other potential predictors of HIV self‐test ordering were identified from Social Cognitive Theoretical underpinnings of the app, and from the literature. Significant predictor variables in bivariate analyses were considered for inclusion in the empiric multivariable model. Demographic variables chosen a priori were then added to a final model estimating adjusted prevalence ratios (aPR). Results Over half of the 417 intervention participants ordered an HIV self‐test kit during the study. In bivariate analyses, ordering a kit was associated with HIV testing history, plans to get tested and reported likelihood of getting tested. In the final model, participants were more likely to order a kit if they reported plans to get tested in the next 3 months (aPR = 1.58, 95% CI: 1.18–2.11) or had not tested for HIV in the past 3 months (aPR = 1.38, 95% CI: 1.13–1.70). There was no difference in HIV self‐test kit ordering by income, race/ethnicity or age. Conclusions HIV testing is an important tool in ending the HIV epidemic and must be accessible and frequent for key populations. This study demonstrates the effectiveness of HIV self‐test kits in reaching populations with suboptimal testing rates and shows that self‐testing may supplement community‐based and clinical testing while helping overcome some of the structural barriers that limit access to annual HIV prevention services for MSM.

BackgroundAlthough research on HIV self-testing (HIVST) has rapidly increased, few studies have explored HIVST uptake in female sex workers (FSW), and none in Malaysia. Therefore, we endeavored to assess the willingness to use HIVST in this at-risk, vulnerable population.MethodsA cross-sectional survey study was conducted among 113 HIV-negative Malaysian FSW in 2017. Participants were recruited using advertisements on social media, flyers, and direct referrals from community-based organizations. Data were collected using self-administered surveys. Multivariable logistic regression was used to identify correlates of willingness to use HIVST.ResultsNearly a third of participants (30.1%) reported they would be willing to use HIVST. Multivariable analyses adjusting for Malay ethnicity, stable housing, living in Kuala Lumpur (KL), years in sex work, age of first sex work, childhood sexual assault, history of HIV testing, and previously in prison indicated that living in KL [adjusted odds ratio (aOR) = 5.214, p = 0.0137] was associated with a greater willingness to use HIVST. In contrast, having stable housing (aOR = 0.100, p = 0.0064) was negatively associated with willingness to use HIVST.ConclusionsOur results indicate that HIVST may potentially enhance the uptake of HIV testing among FSWs living in an urban environment and experiencing unstable housing, but an overall willingness to use HIVST is low. These findings highlight the need for efforts to increase awareness of HIVST among FSWs and additional research on the effective implementation of HIVST for FSW.

Self-testing for COVID-19 may be a preferable strategy for identifying SARS-CoV-2 infection among populations in low- and middle-income settings. To determine South Africans’ values related to COVID-19 self-testing should it become widely available, a cross-sectional survey was administered in Durban, KwaZulu-Natal Province and the King Sabata Dalindyebo sub-district of the Eastern Cape.A 35-question survey was administered to 531 participants (268 female) in one urban and one rural setting of South Africa. Survey participants were randomly selected by household in the rural setting, while in the urban setting participants were approached in randomly selected public places. The survey assessed participants’ likelihood of using and willingness to pay for a COVID-19 self-test and actions they would take following a COVID-19 self-test. The results were analysed using descriptive statistics and bivariate and multivariate regression.Overall, 93.03% of participants supported COVID-19 self-testing, 61.62% of participants were willing to pay for self-testing, and 90.15% indicated they would communicate their results if they tested positive. Rural participants were more positively associated with each of these outcomes compared with urban-based participants. Should they test positive, most participants said they would: go in-person to a health facility for counselling (76.45%), self-isolate (95.85%), notify close contacts (97.74%), and inform their employer (95.14%).COVID-19 self-testing was a preferable option for most participants, although this varied with setting and demographic characteristics. Self-testing may overcome barriers to care for South Africans, but to achieve this, policies for self-testing and delivery methods must not exacerbate individuals’ underlying economic vulnerabilities.

Background: Formative assessments are vital for supporting learning and performance but are also considered to increase the workload of teachers. As self‐assessments in higher education are increasingly facilitated via digital learning environments allowing to offer direct feedback and tracking students' digital learning behaviour these constraints might be reduced. Yet, learning analytics do not make sufficient use of data on assessments. Aims: This exploratory case study uses learning analytics methods for investigating students' engagement with self‐assessments and how this relates to performance in the final exam and self‐reported self‐testing strategies. Materials & Methods: The research study has been conducted at a European university in a twelve‐weeks course of a Bachelor's program in Economic and Business Education including nenroll = 159 participants. During the semester, students were offered nine self‐assessments each including three to eight tasks plus one mid‐term and one exam‐preparation self‐assessment including all prior self‐assessments tasks. The self‐assessment interaction data for each student included: the results of the last self‐assessment attempt, the number of processed self‐assessment tasks, and the time spent on the last self‐assessment attempt, the total self‐assessment attempts, and the first as well as last access of each self‐assessment. Data analytics included unsupervised machine learning and process mining approaches. Results: Findings indicate that students use the self‐assessments predominantly before summative assessments. Two distinct clusters based on engagement with self‐assessments could be identified and engagement was positively related to performance in the final exam. The findings from learning analytics data were also indicated by students' self‐reported use of self‐testing strategies. Discussion: With the help of multiple data from self‐reports, formal exams, and a learning analytics system, the findings provided multiple perspectives on the use of self‐assessments and their relationships with course performance. These findings call for applying assessment analytics and related frameworks in learning analytics as well as providing learners with related adaptive feedback. Conclusion: Future research might investigate different (self‐report) variables for clustering, other student cohorts or self‐assessment forms. Lay Description: What is already known about this topic: Formative assessments are vital for supporting learning and performance.Learning analytics do not make sufficient use of data on assessments. What this paper adds: Students use the self‐assessments predominantly prior to summative assessments.Engagement with self‐assessments was positively related to performance in the final exam. Implications for practice and/or policy: Findings call for applying assessment analytics and implementing related learning analytics frameworks for supporting learning processes and performance.Pedagogically oriented assessment analytics may provide multiple benefits for learners, teachers, schools, and other involved stakeholders.

Rapid and sensitive detection of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is essential for early diagnosis and effective treatment. Nucleic acid testing has been considered the gold standard method for the diagnosis of COVID-19 for its high sensitivity and specificity. However, the polymerase chain reaction (PCR)-based method in the central lab requires expensive equipment and well-trained personnel, which makes it difficult to be used in resource-limited settings. It highlights the need for a sensitive and simple assay that allows potential patients to detect SARS-CoV-2 by themselves. Here, we developed an electricity-free self-testing system based on reverse transcription loop-mediated isothermal amplification (RT-LAMP) that allows for rapid and accurate detection of SARS-CoV-2. Our system employs a heating bag as the heat source, and a 3D-printed box filled with phase change material (PCM) that successfully regulates the temperature for the RT-LAMP. The colorimetric method could be completed in 40 min and the results could be read out by the naked eye. A ratiometric measurement for exact readout was also incorporated to improve the detection accuracy of the system. This self-testing system is a promising tool for point-of-care testing (POCT) that enables rapid and sensitive diagnosis of SARS-CoV-2 in the real world and will improve the current COVID-19 screening efforts for control and mitigation of the pandemic.

Home diagnostic testing is becoming part of the modern medical landscape, but many ethical and policy questions remain unresolved. Most of them first surfaced during the long regulatory deliberations over the home HIV test, the first home test for a contagious illness sold in the United States. Between 1989 and 2012, federal regulators and their consultants debated the ideal metrics for such a test, its benefits, and its potential harms for both individuals and communities. Ultimately, two iterations of the home HIV test were marketed in the United States; neither one of them changed the course of the national HIV epidemic, as hoped. This failure has powerful implications for home testing for other contagious diseases. [ABSTRACT FROM AUTHOR]

Introduction: A vast group of people carrying human immunodeficiency virus (HIV) is unaware of their HIV status. HIV self-testing (HIVST) is a key tool to achieve better expanding of testing by helping patients to be identified, but it faces its' challenges, which need to be carefully discussed. We aimed to introduce and debate the best options and strategies required to maximize the benefits of HIVST in Iran. Material and methods: The authors investigated the above-mentioned question based on a review of 32 articles published between 2007 and 2018 on HIVST. Moreover, focus group discussions (FGDs) and interviews were conducted within 20 people from key populations, with six experts involved. Results: A road map for actualizing HIVST program can be characterized in three major steps, which include: 1) HIVST training and preparing each component by healthcare team; 2) HIVST-assisted and facility-based programs in selected centers, in the presence of supportive consultant assisting each tested person; 3) public access to HIVST kits through pharmacies, internet, and cyberspace. Conclusions: It seems that the dangers and detriments of HIVST are extremely constrained in comparison with its' advantages. Overall, it can be considered as a feasible and effective approach in achieving the goal of identifying an increasing number of potential HIV-positive patients and support healthcare system.

Self-testing, which refers to device independent characterization of the state and the measurement, has been intensively studied in quantum information theory. One of the implicit assumptions in self-testing theorem is, measurement settings should be chosen randomly and independently by each party. The relaxation of this assumption potentially gives untrusted device providers the power to control the device with no quantum feature, even fake the quantum behavior by using the classical strategies within the device. In this paper, we analyze the effects of the reduced measurements independence on self-testing two-qubit entangled states based on the violation of Bell inequalities. By assuming adversary's capabilities, we show to achieve the maximum CHSH violation in this case, four different state-measurements preparations should be provided. Without run information one could not really self-test the underlying system in each run anymore, but it must be equal with one of four entangled systems up to local unitaries.

Background: In 2020, almost 20% of people living with HIV (PLHIV) in Morocco are still unaware of their HIV status. Under these circumstances, HIV self-test (HIVST) can be an efficient additional tool for improving the testing rates in Morocco and reaching the first objective of the UNAIDS 95-95-95 goal. ALCS, a Community-based organization, involved in HIV Testing since 1992, and the Ministry of Health of Morocco conducted, a study on the acceptability and usability of HIVST among Female sex workers (FSW) and MSM (men who have sex with men), using a salivary rapid test. To our knowledge, this is the first study in Morocco exploring these parameters.Methods: We conducted a pilot study on the usability of the OraQuick HIV-1/2 salivary self-test among MSM and FSW visiting the ALCS centers for standard HIV rapid testing in five Moroccan cities. Participants chose whether or not to be assisted by lay provider HIV testing. The counselors sampled them to perform a standard rapid test and then invited them to a private room to perform the HIV self-test simultaneously. In addition, a questionnaire was administered to collect socio-demographic data and to assess their opinion about the usability of the salivary HIVST.Results: Our study was carried out for 5 months and included 492 participants (257 MSM and 233 FSW). The average age of the participants was 29 years among MSM vs 34 years among FSW. The FSW have a lower educational level, 28,8% of them are Illiterate vs. 6,1% of the MSM. Only 18% of participants were aware of the existence of the HIVST, nevertheless, we recorded a very high rate of acceptability (90,6%) of the HIVST. Performing the HIVST was deemed very easy for 92,2% of MSM versus 80,6% of FSW. Although it was found very difficult for six participants, including five FSW, 4 of them could not read or write. Overall, the study registered a high HIV positivity rate (3,8%) and 100% of concordance between HIVST participants' interpretation and standard HIV testing performed by ALCS lay provider HIV testing.Conclusion: Our study shows very high acceptability of HIVST among FSWs and MSM in Morocco, HIV self-testing is still unknown by key populations in Morocco, and the low level of education of FSWs may be a barrier to the use of this test, but with the proposed assistance and adapted demonstration tools, the HIV self-testing will certainly improve access to testing in Morocco.

Objective: To determine the accuracy of self‐testing for proteinuria during pregnancy. Design: Diagnostic accuracy study. Setting: Antenatal clinics, maternity assessment units and inpatient wards at three hospital sites. Population or Sample: 345 pregnant women. Methods: Pregnant women self‐tested in‐clinic for urinary protein using visually read dipsticks with samples then sent for laboratory estimation of the spot protein‐creatinine ratio (PCR) (primary reference test). Secondary index tests included testing by antenatal healthcare professionals and an automated colorimetric reader. Main outcome measures: Sensitivity, specificity, negative predictive value, positive predictive value and likelihood ratios were calculated for self‐testing (primary index test) along with healthcare professional and colorimetric testing compared to the primary reference test (PCR). Results: 335/345 (97%) had sufficient data to be included in the analysis. Self‐testing had a sensitivity of 0.71 (95% confidence interval [CI] 0.62–0.79) and a specificity of 0.89 (95% CI 0.84–0.92) compared to PCR. Sensitivity and specificity of testing by healthcare professionals and the colorimetric reader were similar: sensitivity 0.73 (95% CI 0.64–0.80) and 0.78 (95% CI 0.69–0.85), respectively; specificity 0.88 (95% CI 0.82–0.92) and 0.83 (95% CI 0.78–0.88), respectively. Conclusion: Pregnant women can visually read a dipstick for urinary protein with similar accuracy to antenatal healthcare professionals. Automated colorimetric testing was not significantly different, in contrast to some previous studies. Self‐testing has the potential to form part of a self‐monitoring regime in pregnancy.

Introduction: Early diagnosis is key to achieving the goal of eliminating transmission of HIV and hepatitis B and C. We assessed the uptake, acceptability and interpretability of self‐testing using a 3‐in‐1 rapid diagnostic test (RDT) in facility‐based services. Methods: Stand‐alone testing services were provided free of charge to consenting individuals aged ≥15 years in five facilities in northern Thailand. Clients were invited to choose between self‐testing by fingerprick or venepuncture by a healthcare worker (HCW). In each facility, several clients could simultaneously self‐test in separate private areas using TriQuik™ (Genlantis, San Diego, CA, USA), a single immunochromatographic cassette detecting HIV‐1/2 antibody, hepatitis B surface antigen (HBsAg) and hepatitis C antibody (HCAb). An interactive program on a tablet computer was developed to collect socio‐demographic, behavioural and satisfaction data and provide information to guide the self‐test process, including video instructions, results interpretation and a picture of the cassette for immediate remote review by the HCW. When the HCW interpreted an HIV self‐test as positive, the HCW collected blood by venepuncture for immediate confirmation. Results: Between October 2020 and April 2022, 4119 clients presented for testing for the first time as part of the project. Of them, 3462 (84.0%) opted for self‐testing. Among self‐testers, 1801 (52.0%) were born female, the median age was 27 years (interquartile range, 22–36), 661 (19.1%) belonged to at least one key population and 2124 (61.4%) had never been tested for HIV; 3329 (99.8% of those who answered) reported being "very satisfied" or "satisfied" with the testing process. The proportions of test results interpreted as positive by self‐testers among those interpreted as positive by HCWs were 95% for HIV‐1/2 antibody, 95% for HBsAg and 78% for HCAb. Conclusions: These proportions were higher than those observed in a previous study evaluating another 3‐in‐1 RDT for HIV, HBsAg and HCAb, possibly due to the use of video instructions instead of paper‐based instructions, lower prevalence and co‐infection rates, or lower percentages of clients with low education level. Multiplex self‐testing simplified and streamlined the service delivery process and was well accepted. HCW assistance proved to be essential in a limited number of cases. [ABSTRACT FROM AUTHOR]

Background: Adolescent girls and young women (AGYW) at institutions of higher learning are at high risk of HIV, and conventional HIV testing services may not reach them sufficiently. HIV self-testing (HIVST) scalability can be informed by identifying AGYW who have used or are interested in using HIVST. We aimed to determine factors associated with use and willingness to use HIVST among female university students. Methods: An online cross-sectional survey was conducted among 483 female students at Makerere University, Uganda. Proportions of students who have used or are willing to use HIVST and their associated factors were determined. Modified Poisson regression models were used to estimate prevalence ratios (PR) and their 95% confidence intervals (CI). Results: The median age of the participants was 22 (Interquartile range [IQR] 21–23) years, and 21% had never tested for HIV. Over 93% were willing to utilize HIVST, and 19% had ever used HIV self-test kits. Increasing age (adjusted prevalence ratio [aPR] 1.23 per year, 95% CI 1.07–1.43) was significantly associated with HIVST use. Predictors of willingness to self-test for HIV were college type (arts vs. science-based, aPR 0.92, 95% CI 0.88–0.97), number of sexual partners (one, aPR 1.07, 95% CI 1.03–1.12 or ≥ 2, aPR 1.08, 95% CI 1.04–1.19, vs. none), alcohol (aPR 1.04, 95% CI: 1.00–1.09) or injection drug (aPR 1.04, 95% CI 1.00–1.09) use, a history of sexually transmitted infections in past 12 months (aPR 1.05, 95% CI 1.01–1.09), and HIV testing experience (tested in past 12 months, aPR 1.12, 95% CI 1.02–1.22 or over 12 months, aPR 1.13, 95% CI 1.03–1.24, vs. never tested). Conclusion: HIVST was highly acceptable despite its limited use. This study demonstrates female student characteristics that can be leveraged to scale up HIVST programs in higher institutions of learning. [ABSTRACT FROM AUTHOR]

In this article, we propose and implement a distributed autonomic manager that maintains service level agreements (SLA) for each application scenario. The proposed autonomic manager supports SLAs by configuring the bandwidth ratios for each application scenario and uses an overlay network as an infrastructure. The most important aspect of the proposed autonomic manager is its scalability which allows us to deal with geographically distributed cloud-based applications and a large volume of computation. This can be useful in look ahead optimization and in adaptations using complex models, such as machine learning. We formally prove the safety and liveness properties of the implemented distributed algorithms. Through experiments on the Amazon AWS cloud, using two different use cases, we demonstrate the elasticity and flexibility of the autonomic manager as a measure of its applicability to different cloud applications with different types of workloads. Experiments also demonstrate that increasing the size of a look ahead window, up to a certain size, improves the accuracy of the adaptation decisions by up to 50%. [ABSTRACT FROM AUTHOR]

Background: HIV self-testing is the latest strategy to improve access to testing, diagnosis and treatment. Such strategies are beneficial due to the improved individual- and population-level health outcomes that emerge from early HIV diagnosis. Aims: While most research shows that HIV self-testing is acceptable and feasible, yielding higher numbers of first-time testers and positivity rates, compared to clinic-based testing, little evidence exists outside low- and middle-income countries about such testing. Methods: We implemented GetaKit.ca, a website through which eligible participants could register for and obtain an INSTI® HIV self-testing to their home, and then report the result back. Results: Those who returned to the website were asked to complete a post-test survey, which had a low response rate (42%), but identified satisfaction scores of 92%. Notably, 5% of testers sought in-person care after ordering the self-test, and only 80% of participants agreed that the INSTI® HIV self-test was easy to use. Conclusions: Participants provided tangible solutions to improve this test, which we feel are easy to incorporate and essential to maintain HIV self-testing efforts. [ABSTRACT FROM AUTHOR]

Innovative diagnostic solutions are essential to improve COVID-19 case detection and slow its spread in resource-constrained settings. To understand how South African communities may utilise rapid SARS-CoV-2 antigen self-testing and react to self-test results, we conducted a qualitative study, involving semi-structured interviews and focus group discussions, of healthcare workers, representatives of civil society groups, and potential self-testing implementors. A sex- and location-sensitive thematic analysis approach was used to assess how 52 decision-takers on self-testing roll-out in South Africa perceive the value and utility of this innovative diagnostic approach. Informants suggested South Africans might value a device that allows them to self-test in private, at their own convenience, while avoiding the risk of social stigma and having to wait for COVID-19 test results in a facility. They also emphasised the need for awareness and sensitisation campaigns and to ensure pre-/post-self-test counselling services are easily accessible. Collaboration with traditional leaders and community-based organisations would improve results communication and linkage to counselling and confirmatory testing. SARS-CoV-2 self-testing was perceived to be acceptable to a population already sensitised to the use of HIV self-testing, being a decentralised solution that would help reduce the incidence of COVID-19 and prevent any further deterioration of socio-economic indicators.

Abstract Background Syphilis testing uptake remains low among men who have sex with men (MSM) in many low-and middle-income countries. Syphilis self-testing is an efficacious approach on increasing syphilis testing coverage. However, one unintended consequence is the syphilis self-testing coercion from others (including partners, healthcare providers, friends, etc.). This study aimed to examine the prevalence, pattern and correlates of coerced syphilis self-testing among MSM in China. Methods A nationwide online cross-sectional study was conducted from 14 to 28 July 2018. Sociodemographic characteristics, sexual behaviors and coerced syphilis self-testing variables were collected through a questionnaire that targeted MSM in China. Multivariable logistic regression was used to explore associated factors with syphilis self-testing coercion. Results Overall, 174 MSM were recruited in this study, 31 men (17.8%) reported ever experiencing syphilis self-testing coercion. The most common types of coercion before syphilis self-testing were verbal abuse (38.7%, 12/31) and threatening to end a relationship (38.7%, 12/31). After obtaining the self-test results, men were mostly subjected to end a relationship (45.2%, 14/31) and threaten of violence (35.5%, 11/31). Multivariable logistic regression indicated that men who used condoms inconsistently in the past three months, ever used substances before or during sex, ever had group sex with males and commercial sex were more likely to experience syphilis self-testing coercion. Conclusions Coerced syphilis self-testing was prevalent among MSM in China. Innovative intervention to reduce coerced syphilis self-testing is necessary among MSM in China.

Abstract Background Hepatitis C virus self-testing (HCVST) is an additional approach that may expand access to HCV testing. We conducted a mixed-methods cross-sectional observational study to assess the usability and acceptability of HCVST among people who inject drugs (PWID), men who have sex with men (MSM) and transgender (TG) people in Tbilisi, Georgia. Methods The study was conducted from December 2019 to June 2020 among PWID at one harm reduction site and among MSM/TG at one community-based organization. We used a convergent parallel mixed-methods design. Usability was assessed by observing errors made and difficulties faced by participants. Acceptability was assessed using an interviewer-administered semi-structured questionnaire. A subset of participants participated in cognitive and in-depth interviews. Results A total of 90 PWID, 84 MSM and 6 TG were observed performing HCVST. PWID were older (median age 35 vs 24) and had a lower level of education compared to MSM/TG (27% vs 59%). The proportion of participants who completed all steps successfully without assistance was 60% among PWID and 80% among MSM/TG. The most common error was in sample collection and this was observed more often among PWID than MSM/TG (21% vs 6%; p = 0.002). More PWID requested assistance during HCVST compared to MSM/TG (22% vs 8%; p = 0.011). Acceptability was high in both groups (98% vs 96%; p = 0.407). Inter-reader agreement was 97% among PWID and 99% among MSM/TG. Qualitative data from cognitive (n = 20) and in-depth interviews (n = 20) was consistent with the quantitative data confirming a high usability and acceptability. Conclusions HCVST was highly acceptable among key populations in Georgia of relatively high educational level, and most participants performed HCVST correctly. A significant difference in usability was observed among PWID compared to MSM/TG, indicating that PWID may benefit from improved messaging and education as well as options to receive direct assistance when self-testing for HCV.

Abstract Background Malaysia has an estimated hepatitis C virus (HCV) prevalence of 1.9% among its adult population and a history of providing HCV treatment in the public sector. In 2019, Malaysia launched a 5-year national strategic plan for viral hepatitis control and has been expanding HCV testing and treatment to the primary care and community levels, while actively engaging key populations in services for hepatitis care. The Ministry of Health (MoH) is seeking to specifically understand how to better target HCV services at men who have sex with men (MSM); HCV self-testing could increase the uptake of HCV testing among this group. Methods We aim to integrate HCV antibody self-testing into an existing online platform used for HIV self-testing, to evaluate the acceptability and impact of an online HCV self-testing programme in Malaysia. This is a non-blinded parallel group quasi-randomised superiority study comparing HCV self-testing via an online distribution model with the standard care, which involves attending a clinic for facility-based HCV antibody testing (control, 2:1). Participants will be randomised to either the HCV self-testing via online distribution arm, in which either an oral fluid- or blood-based HCV self-test kit will be mailed to them, or the control arm, where they will be provided with information about the nearest centre with HCV testing. The primary outcome is the number and proportion of participants who report completion of testing. Secondary outcomes include the number and proportion of participants who (a) receive a positive result and are made aware of their status, (b) are referred to and complete HCV RNA confirmatory testing, and (c) start treatment. Acceptability, feasibility, attitudes around HCV testing, and cost will also be evaluated. The target sample size is 750 participants. Discussion This study is one of the first in the world to explore the real-world impact of HCV self-testing on key populations using online platforms and compare this with standard HCV testing services. The outcomes of this study will provide critical evidence about testing uptake, linkage to care, acceptability, and any social harms that may emerge due to HCV self-testing.

Abstract Background Globally, just 21% of the estimated 58 million people living with hepatitis C virus (HCV) know their status. Thus, there is considerable need to scale-up HCV testing if the World Health Organization (WHO) 2030 hepatitis elimination goals are to be achieved. HCV self-testing may assist with this; however, there are currently no data on the real-world impact of HCV self-testing. With an estimated 5% of the general population living with HCV, Pakistan has the second highest HCV burden in the world. This study aims to evaluate the acceptability and impact of home delivery of HCV self-testing for secondary distribution in the context of a house-to-house HCV micro-elimination programme in Pakistan. Methods This is a parallel group, non-blinded, cluster randomised trial comparing secondary distribution of HCV self-testing with secondary distribution of information pamphlets encouraging individuals to visit a testing facility for HCV screening. The cluster allocation ratio is 1:1. Clusters will be randomised either to HCV self-testing distributed via study staff or control clusters where information on HCV will be given and the participant will be requested to attend their local hospital for HCV screening. In both clusters, only households with a member who has not yet been screened as part of the larger micro-elimination project will be included. The primary outcome is the number and proportion of participants who report completion of testing. Secondary outcomes include the number and proportion of participants who a) receive a positive result and are made aware of their status, b) are referred to and complete HCV RNA confirmatory testing, and c) start treatment. Acceptability, feasibility, attitudes towards HCV testing, and cost will also be evaluated. The target sample size is 2,000 participants. Discussion This study will provide the first ever evidence regarding secondary distribution of HCV self-testing. By comparing HCV self-testing with facility-based testing, we will assess whether HCV self-testing increases the uptake of HCV testing. The findings will inform micro-elimination programmes and determine whether HCV self-testing can enable individuals to be reached who may otherwise be missed. Trial Registration This study and was registered on clinicaltrials.gov ( NCT04971538 ) 21 July 2021.

Background: One strategy for reducing spread of COVID-19 is to contain the infection with broad screening, isolating infected individuals, and tracing contacts. This strategy requires widely available, reliable SARS-CoV-2 testing. To increase testing, rapid antigen detection tests (RADTs) were developed for self-sampling, self-testing, and self-interpretation. This study examined diagnostic performance, user acceptability, and safety of nasal self-RADTs compared with polymerase chain reaction (PCR) testing. Methods: Self-RADT kits were distributed at a public COVID-19 test center in Aarhus, Denmark or delivered to participants. Participants reported test results and test preferences. During enrollment, participants reported occurrence and duration of symptoms consistent with COVID-19. Sensitivity and specificity of self-RADT, relative to oropharyngeal PCR testing, were calculated. Results: Among 827 participants, 102 showed positive PCR test results. Sensitivities of the self-RADTs were 65.7% (95% confidence interval [CI]: 49.2–79.2; DNA Diagnostic) and 62.1% (95% CI: 50.1–72.9; Hangzhou), and specificities were 100% (95% CI: 99.0–100; DNA Diagnostic) and 100% (95% CI: 98.9–100; Hangzhou). The sensitivities of both self-RADTs appeared higher in symptomatic participants than in asymptomatic participants. Two of every 3 participants preferred self-RADT over PCR test. Conclusion: Self-performed RADTs were reliable, user-acceptable, and safe among laypeople as a supplement to professionally collected oropharyngeal PCR testing.
