Background: Prevalence of hepatitis C virus (HCV) antibody (Ab) on dried blood spot (DBS) samples in the Australian Needle and Syringe Program Survey (ANSPS) decreased nationally from 57 % in 2015 to 32 % in 2022. We aimed to investigate potential explanations for this decline. Methods: Changes in DBS HCV Ab prevalence were investigated by redefining positive cases as those with those with either a positive HCV Ab test result or a self-reported history of ever having HCV treatment (modified prevalence), examining HCV Ab prevalence by birth and age cohorts, and assessing trends in key risk behaviours. Results: Overall prevalence of DBS HCV Ab declined rapidly and significantly from 57 % in 2015 to 32 % in 2022 (p < 0.001) however modified HCV Ab prevalence remained stable over time (85 % and 88 % in 2015 and 2022, respectively, p = 0.357). The proportion of participants with negative HCV Ab and self-reported HCV infection increased from 20 % in 1995 to 40 % in 2022 (p < 0.001) and the proportion with negative HCV Ab and lifetime HCV treatment increased from 3 % in 1999 to 67 % in 2022 (p < 0.001). We also observed a decreasing trend in DBS HCV Ab prevalence in all birth and age cohorts with a noticeable acceleration in the decline commensurate with the advent of HCV DAA treatment. A long-term decreasing trend was also observed for key risk behaviours (p < 0.001) however the short-term trend was not significant for recent receptive syringe sharing. Conclusions: The temporal decline in HCV Ab prevalence appears related to reduced sensitivity of DBS HCV Ab detection with viral clearance following treatment. Since 2016, HCV treatment uptake has increased markedly including among people who inject drugs. In this context, continuing to monitor HCV Ab prevalence by DBS testing is problematic, with a shift to surveillance of active infection the most relevant to guide policy and practice in this setting.

Objective: To identify the correlates of stunting and investigate their population-level impacts among children under 5 years in sub-Saharan Africa. Methods: Data from 179 572 children under five were included from nationally representative surveys conducted across 24 sub-Saharan African countries (2015-2022). Multivariable logistic regression models and population-level impacts of risk factors were estimated to highlight their contributions to stunting prevalence across the study regions. Results: Stunting prevalence ranged from 18% to 54%, with rates exceeding 50% in Burundi. Lack of basic household amenities was consistently associated with stunting, accounting for 24%-57% of cases across regions. Limited access to mass media further contributed to stunting rates, highlighting the role of education and awareness in preventing malnutrition. Maternal characteristics, such as lack of education and health insurance, were also significant risk factors, with adjusted odds ratios (aORs) ranging from 1.44 to 2.24. Conclusions: Socio-economic disparities are key risk factors for stunting in sub-Saharan Africa. These factors were statistically associated with a substantial proportion of stunting cases in high-prevalence regions. Targeted interventions to reduce inequalities, improve maternal education and expand essential services access are vital to achieving global nutrition targets, including the Sustainable Development Goal of reducing child stunting by 40% by 2025.

Background: Despite advances in the management and treatment of HIV, identifying risks for disengagement are essential to maximize positive outcomes. The current study investigated the validity of the Clinical Complexity Rating Scale for HIV (CCRS-HIV), a risk-prediction tool, by assessing agreement between patient and clinician scores of patient complexity. Methods: 207 patients completed the patient version of the CCRS-HIV (CCRS-HIVP), and six Attending Medical Officers (AMOs) caring for those individuals completed the original clinician version (CCRS-HIVC). Kappa statistics, sensitivity and specificity were used to assess patient-clinician agreement. Results: Patient-clinician agreement was highest for problematic crystal methamphetamine use (86%), polypharmacy (84%) and other physical health concerns (67%). Cut-offs of 40 and 45 for the total CCRS-HIV score were identified as most appropriate, with high sensitivity (79.31% and 76.0% respectively). Conclusions: Overall agreement between the clinician and patient complexity scores was high. These findings provide further evidence of the validity of the scale. The study demonstrates that the unique role of AMOs at the center contributes to them knowing their patients well, allowing them to manage and refer when required for interdisciplinary care which likely contributes to their ongoing engagement in care and may account for the high level of agreement.

The self-collection of vaginal swabs and point-of-care testing and treatment of sexually transmitted infections (STIs) is reported from several low-and middle-income countries. However, the reporting on women's experiences of self-collection and same-day testing and treatment of STIs is less well described. In this paper, we present the acceptability of self-collected vaginal swabs and point-of-care testing and treatment among pregnant women enrolled in a clinical trial (Women and Newborn Trial of Antenatal Intervention and Management - WANTAIM) in Papua New Guinea. Semi-structured interviews were conducted among 54 women enrolled into WANTAIM to identify the acceptability of the test and treat approach. Analysis of qualitative data used deductive and inductive thematic analysis applying Sekhon, Cartwright and Francis' acceptability theoretical framework. Most women reported that they understood that the vaginal swab was to identify infections that may affect their unborn baby; however, some were unsure about the specific infections they were being tested for. Among women who tested positive for an STI, some were unsure what they had been treated for. Overall, the self-collection of vaginal swabs for STI testing during pregnancy was highly acceptable.

Background: Digital interventions can help to overcome barriers to care, including stigma, geographical distance, and a lack of culturally appropriate treatment options. "We Can Do This" is a web-based app that was designed with input from cultural advisors and end users to support Aboriginal and Torres Strait Islander people seeking to stop or reduce their use of methamphetamine and increase psychosocial well-being. Objective: This study aimed to evaluate the effectiveness of the "We Can Do This" web-based app as a psychosocial treatment for Aboriginal and Torres Strait Islander people who use methamphetamine. Methods: The web app was evaluated using a randomized waitlist controlled parallel group trial. Participants were Aboriginal and Torres Strait Islander people aged 16 years or older who self-identified as having used methamphetamine at least weekly for the past 3 months. Participants were randomized on a 1:1 ratio to receive either access to the web-based app for 6 weeks or a waitlist control group. Both groups received access to a website with harm minimization information. The primary outcome was days of methamphetamine use in the past 4 weeks assessed at 1, 2, and 3 months post randomization. Secondary outcomes included severity of methamphetamine dependence (Severity of Dependence Scale [SDS]), psychological distress (Kessler 10 [K10]), help-seeking behavior, and days spent out of role due to methamphetamine use. Results: Participants (N=210) were randomized to receive either access to the web-based app (n=115) or the waitlist control condition (n=95). Follow-up was 63% at 1 month, 57% at 2 months, and 54% at 3 months. There were no significant group differences in days of methamphetamine use in the past 4 weeks at 1 the month (mean difference 0.2 days, 95% CI -1.5 to -2), 2 months (mean difference 0.6 days, 95% CI -1 to 2.4 days) or 3 months (mean difference 1.4 days, 95% CI -0.3 to 3.3 days) follow-up. There were no significant group differences in K10 scores, SDS scores, days out of role, or help-seeking at any of the 3 follow-up timepoints. There was poor adherence to the web-based app, only 20% of participants in the intervention group returned to the web-based app after their initial log-in. Participants cited personal issues and forgetting about the web-based app as the most common reasons for nonadherence. Conclusions: We found poor engagement with this web-based app. The web-based app had no significant effects on methamphetamine use or psychosocial well-being. Poor adherence and low follow-up hindered our ability to accurately evaluate the effectiveness of the web-based app. Future web-based apps for this population need to consider methods to increase participant engagement.
