RESUMO
Background Australia imposes restrictions for people living with HIV (PLHIV) applying for permanent residency (PR), including spending less than AUD51,000 on medical costs over 10years. Some PLHIV opted for suboptimal and cheaper antiretroviral therapy (ART) regimens to increase their chances of receiving PR. We collated a case series to examine PLHIV on suboptimal ART because of visa issues. Methods We identified all patients applying for a PR in Australia who obtained nevirapine, efavirenz or zidovudine between July 2022 and July 2023 from the Melbourne Sexual Health Centre. Pathology results and records detailing psychological issues relating to the patients' wishes to remain on suboptimal ART were extracted from clinical records by two researchers. Results We identified six patients with a mean age of 39years migrating from Asian and European countries. Three patients used efavirenz, and three used nevirapine. All desired to remain on cheaper, suboptimal ART to stay below visa cost thresholds, which they considered to aid favourably with their application. Four displayed stress and anxiety arising from visa rejections, appeal deadlines and the lengthy visa application process. Conclusions Despite access to more effective and safer ART, we identified patients who chose to remain on cheaper ART to improve chances of obtaining an Australian visa, potentially putting their health at risk. We found significant evidence of stress and anxiety among patients. There is a need to review and revise current migration policies and laws in Australia that discriminate against PLHIV and jeopardise public health.

STATEMENT OF PROBLEM: Type 3 oligodontia is the most dentoalveolar deficient manifestation of congenital tooth absence. There is a need to rehabilitate these children functionally and esthetically to improve quality of life. PURPOSE: The purpose of this retrospective case series was to evaluate the short- and intermediate-term outcomes of the dental treatment provided in a children's hospital and to develop a sequential interdisciplinary treatment planning protocol from infancy to the completion of jaw development. MATERIAL AND METHODS: A total of 10 patients were included in this retrospective longitudinal case series report. Different interventions had been carried out at times related to growth and development of the jaws. Implant-supported fixed dental prostheses were provided after the lateral growth of the anterior mandible had stabilized at around 12 years of age. Definitive mandibular prostheses were provided after the cessation of growth and following maxillary treatment. Treatment for the maxilla was more complex. Bone grafted and graftless implant-supported fixed prostheses were offered as alternatives to a complete denture. Implant stability and soft tissue response were evaluated at prosthesis removal. RESULTS: Seven patients received a 4-implant and 2 a 5-implant-supported immediately loaded fixed mandibular prosthesis. One patient elected to maintain the interim complete denture. Of the 38 implants, 2 failed and were satisfactorily replaced. In the maxilla, 4 patients elected to maintain a complete denture, and 6 received a maxillary implant-supported fixed prosthesis: 1 with bilateral sinus lift bone grafting and 6 regular implants; 1 with 6 regular implants; 1 with 4 regular implants; 2 with bilateral zygoma implants plus 2 regular anterior implants; and 1 with 4 zygoma implants. No implant failures were recorded in the maxilla. Follow-up for mandibular treatment ranged from 1 to 12 years and for maxillary treatment 1 to 9 years. All implants were classified as asymptomatic and surviving. CONCLUSIONS: The use of fixed implant-supported prostheses in selected individuals with Type 3 oligodontia can improve functional and esthetic outcomes as compared with the use of removable prostheses alone. Implant-supported prostheses require an interdisciplinary approach from early childhood until growth cessation.
RESUMO
Long-acting injectable regimens for HIV treatment have been developed which are less frequent, more discreet, and more desirable for some people living with HIV (PLHIV) and may help reduce stigma-related barriers to HIV treatment. However, there is little information on the relationship between reported stigma and preference for these newer treatments. We characterized anticipated, experienced, and internalized HIV stigma and examined the associations with treatment preferences among an international sample of PLHIV. Data came from the international, web-based, cross-sectional study called "Positive Perspectives" conducted among PLHIV aged ≥ 18 years in 25 geographic locations during 2019 (n = 2389). Descriptive analyses were stratified among East Asian (n = 230) vs. non-Asian (n = 2159) participants. Results showed that prevalence of anticipated stigma was significantly higher among East Asian than non-Asian participants (72.2%[166/230] vs. 63.8%[1377/2159], p = 0.011). A significantly higher percentage of East Asian (68.7%[158/230]) than non-Asian participants (43.3%[935/2159] indicated that someone finding their HIV pills would cause them much "stress or anxiety" (p < 0.001). Actions taken by some PLHIV to prevent unwanted disclosure included restricting who they shared their HIV status with, hiding their HIV pills, or even skipping a dose altogether because of privacy concerns. Overall, 50.0%[115/230] East Asian participants believed HIV would reduce their lifespan and 43.0%[99/230] no longer planned for their old age because of HIV. Anticipated stigma was strongly associated with receptivity to non-daily regimens. Concerted efforts to reduce stigma and deliver flexible treatment options that address the unmet treatment needs of PLHIV, including confidentiality concerns, may improve their health-related quality of life.

INTRODUCTION: Recent 3-dimensional technology advancements have resulted in new techniques to improve the accuracy of intraoperative transfer. This study aimed to validate the accuracy of computer-aided design and manufacturing (CAD-CAM) customized surgical cutting guides and fixation plates on mandibular repositioning surgery performed in isolation or combined with simultaneous maxillary repositioning surgery. METHODS: Sixty patients who underwent mandibular advancement surgery by the same surgeon were retrospectively evaluated by 3-dimensional surface-based superimposition. A 3-point coordinate system (x, y, z) was used to identify the linear and angular discrepancies between the planned movements and actual outcomes. Wilcoxon rank sum test was used to compare the outcomes between the mandible-only and the bimaxillary surgery groups with significance at P <0.05. Pearson correlation coefficient compared planned mandible advancement to the outcome from advancement planned. The centroid, which represents the mandible as a single unit, was computed from 3 landmarks, and the discrepancies were evaluated by the root mean square error (RMSE) for clinical significance set at 2 mm for linear discrepancies and 4° for angular discrepancies. RESULTS: There was no statistically significant difference between the planned and actual position of the mandible in either group when considering absolute values of the differences. When considering raw directional data, a statistically significant difference was identified in the y-axis suggesting a tendency for under-advancement of the mandible in the bimaxillary group. The largest translational RMSE for the centroid was 0.77 mm in the sagittal dimension for the bimaxillary surgery group. The largest rotational RMSE for the centroid was 1.25° in the transverse dimension for the bimaxillary surgery group. Our results show that the precision and clinical feasibility of CAD-CAM customized surgical cutting guides and fixation plates on mandibular repositioning surgery is well within clinically acceptable parameters. CONCLUSION: Mandibular repositioning surgery can be performed predictably and accurately with the aid of CAD-CAM customized surgical cutting guides and fixation plates with or without maxillary surgery.

OBJECTIVES: While current antiretroviral and care strategies can effectively suppress HIV, achieving optimal quality of life (QoL) requires a wider consideration of clients' well-being, the complexity of individuals' lives and social determinants of health. The objective of this commentary was to develop a definition of client-led care in the Australian context and its key supporting principles for people living with HIV (PLHIV). METHODS: The authors used two sources of evidence to support their HIV community experience with client-led care: (1) a scoping review of the literature, and (2) consultations with colleagues who were PLHIV advocates or HIV specialist physicians. The findings from the scoping review and consultations were summarised and the key principles of client-led care compared with those identified by the authors. RESULTS: Seven articles met the inclusion criteria for qualitative analysis in the scoping review. Five PLHIV advocates and three HIV specialist physicians were consulted. Key principles supporting client-led care identified by the authors based on their experience centred around the themes of: (1) clients and healthcare providers working in partnership, (2) information and communication, (3) coordinating access to care, (4) building trust, and (5) respect for client's needs and preferences. The principles identified by the authors were supported by those of the scoping review and colleague consultations. CONCLUSIONS: A client-led approach can complement conventional HIV care strategies and enable empowerment and greater engagement with care, potentially improving the care continuum and overall QoL for individuals living with HIV who can, and want to, lead their own care.

OBJECTIVES: 'Undetectable equals Untransmittable' (U=U) is an empowering message that may enable people living with HIV (PLHIV) to reach and maintain undetectability. We estimated the percentage of PLHIV who ever discussed U=U with their main HIV care provider, and measured associations with health-related outcomes. Secondarily, we evaluated whether the impact of the U=U message varied between those who heard it from their healthcare provider (HCP) vs from elsewhere. METHODS: Data were from the 25-country 2019 Positive Perspectives Survey of PLHIV on treatment (n=2389). PLHIV were classified as having discussed U=U with their HCP if they indicated that their HCP had ever told them about U=U. Those who had not discussed U=U with their HCP but were nonetheless aware that 'My HIV medication prevents me from passing on HIV to others' were classified as being made aware of U=U from non-HCP sources. Multivariable logistic regression was used to measure associations between exposure to U=U messages and health outcomes. RESULTS: Overall, 66.5% reported ever discussing U=U with their HCP, from 38.0% (South Korea) to 87.3% (Switzerland). Prevalence was lowest among heterosexual men (57.6%) and PLHIV in Asia (51.3%). Compared with those unaware of U=U, those reporting U=U discussions with their HCP had lower odds of suboptimal adherence (AOR=0.59, 95% CI 0.44 to 0.78) and higher odds of self-reported viral suppression (AOR=2.34, 95% CI 1.72 to 3.20), optimal sexual health (AOR=1.48, 95% CI 1.14 to 1.92) and reporting they 'always shared' their HIV status (AOR=2.99, 95% CI 1.42 to 6.28). While exposure to U=U information from non-HCP sources was beneficial too, the observed associations were attenuated relative to those seen with reported discussions with HCPs. CONCLUSION: HCP discussion of U=U with PLHIV was associated with favourable health outcomes. However, missed opportunities exist since a third of PLHIV reported not having any U=U discussion with their HCP. U=U discussions with PLHIV should be considered as a standard of care in clinical guidelines.

While geographic differences in HIV burden are well documented, less is known about regional differences in perceived treatment needs. To fill this gap, the 2019 Positive Perspectives study of people living with HIV (PLHIV) was conducted in 25 countries across Northern America, Latin America, the Asian region, Europe (EU/Schengen countries), Russia, Australia, and South Africa (n = 2389). Overall mean duration of HIV was 10.1 (SD = 9.6) years. The perception that HIV had a negative impact on day-to-day life was lowest among participants from South Africa (14.0%[25/179]) and highest among participants from the Asian region (55.2%[127/230]). Most of the regional gap in the perception that HIV had a negative impact on daily life was explained by regional differences in medication-related unmet needs, stigma, demographic factors, and comorbidities. The percentage who felt they understood their treatment was highest among participants from Australia (87.5%[105/120]) and lowest among those from Russia (62.0%[93/150]), the Asian region (62.2%[143/230]), and South Africa (62.6%[112/179]). Among participants from Northern America, Europe, and Latin America, the treatment goals with the largest absolute increase in perceived importance, from time of starting treatment to time of survey among those diagnosed for ≥1 year, were minimizing the long term impact of antiretroviral treatment and keeping the number of medicines in their antiretroviral regimen at a minimum. Tailored approaches to care of PLHIV are needed as different regions have different disease burden and treatment needs. Equitable approaches to HIV care are needed across and within regions to ensure that patients' unmet needs and preferences are addressed to improve their overall wellbeing and health-related quality of life.

To assess challenges with daily oral antiretroviral therapy (ART), we analyzed data for 2389 participants in the 2019 Positive Perspectives survey of people living with HIV in 25 countries. ART-related challenges reported included difficulty swallowing pills (33.1% [790/2389]); stress from daily dosing routine (33.3% [795/2389]); bad memories from daily intake of HIV medication (35.1%[839/2389]), and concern "that having to take pills every day means a greater chance of revealing my HIV status to others" (37.9% [906/2389]). Individuals who felt empowered by daily oral dosing ["taking my pill(s) every day reassures me that my HIV is being kept under control"] had 69% higher odds of optimal overall health (AOR 1.69, 95% CI 1.40-2.04). Conversely, odds of optimal overall health were lower among those who felt daily pill intake "limits my day-to-day life" (AOR 0.53, 95% CI 0.44-0.64). These findings show that there is need for increased flexibility of ART delivery to meet diverse patient needs.

We assessed patient-provider communication in HIV care; data were from the 2019 Positive Perspectives Survey of people living with HIV (PLHIV) from 25 countries (n = 2389). A significantly greater proportion of recently diagnosed individuals were interested in being involved when it comes to decisions about their HIV treatment compared with any other group (72.8% [399/548], 63.1% [576/913], and 62.6% [581/928], diagnosis year: 2017-2019, 2010-2016, and pre-2010 respectively) but reported less understanding of their treatment compared with those reporting the longest duration (66.8% [366/548], 68.6% [626/913], and 77.3% [717/928], respectively). One-third of PLHIV with salient treatment-related concerns were uncomfortable discussing with providers. Of participants who felt that their HIV medication limited their life but did not discuss their concerns with their provider (n = 203), top reasons for not discussing were: perception nothing could be done (49.3% [100/203]), provider never brought up the issue (37.9% [77/203]), and not wanting to appear difficult (30.5% [62/203]). To continue to identify and address unmet treatment needs among PLHIV, providers need to ensure that there is ongoing open dialogue.

BACKGROUND: Eptinezumab, an anti-calcitonin gene-related peptide monoclonal antibody recently approved in the United States for preventive treatment of migraine in adults, was found to be well tolerated in double-blind, placebo-controlled studies in patients with episodic and chronic migraine. The objective of the PREVAIL study was to evaluate the long-term safety, immunogenicity, and impact on patient-reported outcomes of repeat doses of eptinezumab in patients with chronic migraine. METHODS: PREVAIL was an open-label, phase 3 trial comprising a 48-week treatment phase followed by a second 48-week treatment phase. Adults with chronic migraine received eptinezumab 300 mg by 30-min intravenous administration every 12 weeks for up to 8 doses. Patients were followed for 20 weeks after the final infusion (end-of-study visit at week 104). RESULTS: Overall, 128 adults (mean age, 41.5 years) with chronic migraine were included. During the 2 years, the most frequently reported treatment-emergent adverse events were nasopharyngitis (14.1%), upper respiratory tract infection (7.8%), sinusitis (7.8%), influenza (6.3%), bronchitis (5.5%), and migraine (5.5%). The rate of study-drug discontinuation due to adverse events was 6.3%, which included 3 patients with infusion-related hypersensitivity. The incidence of anti-eptinezumab antibodies peaked at week 24 and declined despite continued dosing, to nondetectable levels at week 104. Improvements in patient-reported outcomes were observed at first assessment (week 4) and generally sustained through week 104. CONCLUSION: In adults with chronic migraine, eptinezumab 300 mg demonstrated a favorable safety profile, limited long-term immunogenicity, early and sustained reductions in migraine-related burden, and improvements in health-related quality of life over 2 years. TRIAL REGISTRATION: ClinicalTrials.gov (Identifier: NCT02985398 ).

OBJECTIVE: To evaluate the efficacy and safety of eptinezumab, a humanized anti-calcitonin gene-related peptide monoclonal antibody, in the preventive treatment of episodic migraine. METHODS: The PRevention Of Migraine via Intravenous ALD403 Safety and Efficacy-1 (PROMISE-1) study was a phase 3, multicenter, randomized, double-blind, placebo-controlled, parallel-group study. Adults with episodic migraine were randomized to eptinezumab 30 mg, 100 mg, 300 mg, or placebo for up to four intravenous (IV) doses administered every 12 weeks. The primary endpoint was change from baseline in monthly migraine days (MMDs) over weeks 1-12. RESULTS: A total of 888 patients received treatment across 84 study sites. Mean MMDs at baseline was â¼8.6 across treatment groups. Eptinezumab 100 mg and 300 mg met the primary endpoint, significantly reducing MMDs across weeks 1-12 compared with placebo (30 mg, -4.0; 100 mg, -3.9, p = 0.0182; 300 mg, -4.3; placebo, -3.2, p = 0.0001). Treatment-emergent adverse events were reported by 58.4% (30 mg), 63.2% (100 mg), 57.6% (300 mg), and 59.5% (placebo) of patients. Treatment-emergent adverse events reported by ≥2% of eptinezumab-treated patients at an incidence greater than placebo included: upper respiratory tract infection (30 mg, 11.4%; 100 mg, 9.9%; 300 mg, 10.3%; placebo, 7.2%), and fatigue (30 mg, 2.3%; 100 mg, 3.6%; 300 mg, 3.6%; placebo, <1%). CONCLUSION: Eptinezumab (100 mg or 300 mg) significantly reduced migraine frequency, was well tolerated, and had an acceptable safety profile when used for the preventive treatment of migraine in adults with episodic migraine. ClinicalTrials.gov identifier: NCT02559895.

Modern antiretroviral therapy (ART) has improved the lives of people living with HIV (PLHIV) but currently requires daily adherence. We assessed prevalence and correlates of suboptimal adherence, and measured associations with self-reported health outcomes. Data were from web-based surveys of confirmed HIV+ adults on antiretroviral treatment within 25 countries during 2019 (n = 2389). Suboptimal adherence was a report of ≥1 reason for missing ART ≥5 times within the past month. Multivariable logistic regression examined associations between suboptimal adherence and self-reported overall health and virologic suppression. Overall, 24.1% (575/2389) reported suboptimal adherence, from 10.0% (5/50) in Austria, to 62.0% (31/50) in China. The most common reasons for missing ART ≥5 times in the overall population were feeling depressed/overwhelmed (7.4%, 176/2389), trying to forget about HIV (7.0%, 168/2389), and work (6.1%, 145/2389). Correlates of suboptimal adherence included being heterosexual, <50 years old, ≤high school, having gastrointestinal treatment side effects, and privacy concerns. Odds of suboptimal overall health were 1.41 (95%CI, 1.11-1.80), 2.10 (95%CI, 1.65-2.68), and 2.55 (95%CI, 2.00-3.25) among those who reported the maximum number of times missed ART for any reason within the past month as 1, 2-4, or ≥5 times respectively, vs not missing at all. Odds of virologic nonsuppression were 1.80 (95%CI, 1.33-2.45), and 2.24 (95%CI, 1.66-3.02) for 2-4, or ≥5 times of missed ART respectively, vs not missing at all; missing for only 1 time was not significantly associated with virologic nonsuppression. Novel ART strategies designed to improve adherence along with interventions to empower PLHIV and support self-medication may improve health outcomes and quality of life.

BACKGROUND: Analytical treatment interruptions (ATI) are commonly used clinical endpoints to assess interventions aimed at curing HIV or achieving antiretroviral therapy (ART)-free HIV remission. Understanding the acceptability of ATI amongst people living with HIV (PLHIV) and their HIV healthcare providers (HHP) is limited. METHODS: Two online surveys for PLHIV and HHP assessed awareness and acceptability of ATI, and understanding of the prospect for HIV cure in the future. Responses were collected from July 2017-January 2018. A descriptive analysis was performed and similar questions across the two surveys were compared using χ squared test. RESULTS: 442 PLHIV and 144 HHP completed the survey. 105/400 (26%) PLHIV had ever interrupted ART, 8% of which were in a clinical trial. Altruistic motivations were drivers of participation of PLHIV in cure related research. 81/135 (60%) HHP would support their patients wishing to enrol in an HIV cure-focused trial, but fewer would promote and allow such participation (25% and 31% respectively). Compared to HHP, PLHIV were more likely to believe that an HIV cure would be achievable within 10 years (55% vs. 19%, p < 0.001), had less awareness of ATI (46% vs. 62%, p < 0.001) and were less likely to have had experience of either participation or enrolment in an ATI study (5% vs. 18%, p < 0.001) CONCLUSION: PLHIV were more optimistic about the potential for HIV cure. HHP had more direct experience with HIV cure-focused studies. Educational strategies are required for both groups to increase understanding around ATIs in HIV cure research but should be tailored specifically to each group.

BACKGROUND: PROMISE-2 was a phase 3, randomized, double-blind, placebo-controlled study that evaluated the efficacy and safety of repeat intravenous (IV) doses of the calcitonin gene-related peptide-targeted monoclonal antibody eptinezumab (ALD403) for migraine prevention in adults with chronic migraine. This report describes the results of PROMISE-2 through 24 weeks of treatment. METHODS: Patients received up to two 30-min IV administrations of eptinezumab 100 mg, 300 mg, or placebo separated by 12 weeks. Patients recorded migraine and headache endpoints in a daily eDiary. Additional assessments, including patient-reported outcomes, were performed at regularly scheduled clinic visits throughout the 32-week study period (screening, day 0, and weeks 2, 4, 8, 12, 16, 20, 24, and 32). RESULTS: A total of 1072 adults received treatment: eptinezumab 100 mg, n = 356; eptinezumab 300 mg, n = 350; placebo, n = 366. The reduction in mean monthly migraine days observed during the first dosing interval (100 mg, - 7.7 days; 300 mg, - 8.2 days; placebo, - 5.6 days) was further decreased after an additional dose (100 mg, - 8.2 days; 300 mg, - 8.8 days; placebo, - 6.2 days), with both doses of eptinezumab demonstrating consistently greater reductions from baseline compared to placebo. The ≥50% and ≥ 75% migraine responder rates (MRRs) increased after a second dose, with more eptinezumab-treated patients experiencing migraine response than placebo patients (≥50% MRRs weeks 13-24: 100 mg, 61.0%; 300 mg, 64.0%; placebo, 44.0%; and ≥ 75% MRRs weeks 13-24: 100 mg, 39.3%; 300 mg, 43.1%; placebo, 23.8%). The percentages of patients who improved on patient-reported outcomes, including the Headache Impact Test and Patient Global Impression of Change, increased following the second dose administration at week 12, and were greater with eptinezumab than with placebo at all time points. No new safety concerns were identified with the second dose regarding the incidence, nature, and severity of treatment-emergent adverse events. CONCLUSION: Eptinezumab 100 mg or 300 mg administered IV at day 0 and repeated at week 12 provided sustained migraine preventive benefit over a full 24 weeks and demonstrated an acceptable safety profile in patients with chronic migraine. TRIAL REGISTRATION: ClinicalTrials.gov (Identifier: NCT02974153 ). Registered November 23, 2016.

BACKGROUND: Advances in medical treatment for HIV are driving major changes in HIV policy and practice, including the encouragement of intake and adherence to HIV antiretroviral treatment (ART) by people living with HIV (PLHIV) for both personal and public health benefits. However, there is increasing recognition that achieving these goals will require a concurrent focus on the broader psychological and social wellbeing of PLHIV. Increasingly calls are being been made to incorporate a stronger focus on quality of life (QoL) of PLHIV into HIV prevention policy. In order to achieve this goal, HIV community, support and healthcare services need a valid, short and practical way to evaluate QoL of PLHIV accessing their programs. Current QoL measures are either long, complex, restricted in their use, or expensive. To address these shortcomings, the PozQoL study aimed to develop, test and validate a short and freely available scale assessing QoL among PLHIV. METHODS: Drawing on a literature review, the prioritisation of domains and development of the initial pool of items was conducted in consultation with PLHIV community organisations in Australia. The items covered health concerns, psychological, social, and functional wellbeing. Testing involved a baseline and a follow-up survey of 465 adult Australians living with HIV. Participants were recruited through social media and various community organizations nationwide. The survey included the pilot PozQoL scale and other validated measures of health and wellbeing. RESULTS: Guided by an Exploratory Factor Analysis and conceptual considerations, a 13-item scale was developed. The PozQoL scale demonstrated high levels of fit in a Confirmatory Factor Analysis, very good internal consistency, test-retest reliability, and concurrent validity with other measures that approximated different aspects of QoL. CONCLUSION: The PozQoL scale has been tested in a diverse sample of adult PLHIV living in Australia, demonstrating very good reliability and validity. The insights from PLHIV and other stakeholders supported the balancing of statistical rigour and conceptual accuracy. The scale is now ready to be implemented and field-tested across a range of community, support and healthcare programs for PLHIV. This will make a significant contribution to the evaluation and enhancement of programs for PLHIV.

Guided bone regeneration is one of the most common surgical treatment modalities performed when an additional alveolar bone is required to stabilize dental implants in partially and fully edentulous patients. The addition of a barrier membrane prevents non-osteogenic tissue invasion into the bone cavity, which is key to the success of guided bone regeneration. Barrier membranes can be broadly classified as non-resorbable or resorbable. In contrast to non-resorbable membranes, resorbable barrier membranes do not require a second surgical procedure for membrane removal. Commercially available resorbable barrier membranes are either synthetically manufactured or derived from xenogeneic collagen. Although collagen barrier membranes have become increasingly popular amongst clinicians, largely due to their superior handling qualities compared to other commercially available barrier membranes, there have been no studies to date that have compared commercially available porcine-derived collagen membranes with respect to surface topography, collagen fibril structure, physical barrier property, and immunogenic composition. This study evaluated three commercially available non-crosslinked porcine-derived collagen membranes (Striate+TM, Bio-Gide® and CreosTM Xenoprotect). Scanning electron microscopy revealed similar collagen fibril distribution on both the rough and smooth sides of the membranes as well as the similar diameters of collagen fibrils. However, D-periodicity of the fibrillar collagen is significantly different among the membranes, with Striate+TM membrane having the closest D-periodicity to native collagen I. This suggests that there is less deformation of collagen during manufacturing process. All collagen membranes showed superior barrier property evidenced by blocking 0.2-16.4 µm beads passing through the membranes. To examine the immunogenic agents in these membranes, we examined the membranes for the presence of DNA and alpha-gal by immunohistochemistry. No alpha-gal or DNA was detected in any membranes. However, using a more sensitive detection method (real-time polymerase chain reaction), a relatively strong DNA signal was detected in Bio-Gide® membrane, but not Striate+TM and CreosTM Xenoprotect membranes. Our study concluded that these membranes are similar but not identical, probably due to the different ages and sources of porcine tissues, as well as different manufacturing processes. We recommend further studies to understand the clinical implications of these findings.
RESUMO
Introduction: Antiretroviral therapy for people living with HIV-1 must be taken lifelong due to the persistence of latent virus in long-lived and proliferating CD4+ T cells. Vitamin D3 is a steroidal gene transcription regulator which exerts diverse effects on immune and epithelial cells including reductions in CD4+ T cell proliferation and improvement in gut barrier integrity. We hypothesised that a high dose of vitamin D3 would reduce the size of the HIV-1 reservoir by reducing CD4+ T cell proliferation. Methods: We performed a randomised placebo-controlled trial evaluating the effect of 24 weeks of vitamin D3 (10,000 international units per day) on the HIV-1 reservoir and immunologic parameters in 30 adults on antiretroviral therapy; participants were followed for 12 weeks post-treatment. The primary endpoint was the effect on total HIV-1 DNA at week 24. Parameters were assessed using mixed-effects models. Results: We found no effect of vitamin D3 on the change in total HIV-1 DNA from week 0 to week 24 relative to placebo. There were also no changes in integrated HIV-1 DNA, 2-long-terminal repeat (2-LTR) circles or cell-associated HIV-1 RNA. Vitamin D3 induced a significant increase in the proportion of central memory CD4+ and CD8+ T cells, a reduction in the proportion of senescent CD8+ T cells and a reduction in the natural killer cell frequency at all time points including week 36, 12 weeks after the study drug cessation. At week 36, there was a significant reduction in total HIV-1 DNA relative to placebo and persistently elevated 25-hydroxyvitamin D levels. No significant safety issues were identified. Conclusions: Vitamin D3 administration had a significant impact on the T cell differentiation but overall effects on the HIV-1 reservoir were limited and a reduction in HIV-1 DNA was only seen following cessation of the study drug. Additional studies are required to determine whether the dose and duration of vitamin D3 can be optimised to promote a continued depletion of the HIV-1 reservoir over time.

RESUMO
INTRODUCTION: Structural stigma in the global HIV response is a "moving target" that constantly evolves as the epidemic changes. Tackling structural stigma requires an understanding of the drivers and facilitators of stigma in complex community, policy and health systems. In this paper, we present findings from a study adopting a systems perspective to understand how to tackle structural stigma via the Meaningful Involvement of People with HIV/AIDS (MIPA), while highlighting the challenges in demonstrating peer leadership from people living with HIV (PLHIV). METHODS: Through a long-term ongoing community-research collaboration (2015-2023), the study applied systems thinking methods to draw together the insights of over 90 peer staff from 10 Australian community and peer organizations. We used hypothetical narratives, affinity methods and causal loop diagrams to co-create system maps that visualize the factors that influence the extent to which peer leadership is expected, respected, sought-out and funded in the Australian context. We then developed draft indicators of what we should see happening when PLHIV peer leadership and MIPA is enabled to challenge structural stigma. RESULTS: Participants in the collaboration identified the interactions at a system level, which can enable or constrain the quality and influence of PLHIV peer leadership. Participants identified that effective peer leadership is itself affected by structural stigma, and peer leaders and the programmes that support and enable peer leadership must navigate a complex network of causal pathways and strategic pitfalls. Participants identified that indicators for effective PLHIV peer leadership in terms of engagement, alignment, adaptation and influence also required indicators for policy and service organizations to recognize their own system role to value and enable PLHIV peer leadership. Failing to strengthen and incorporate PLHIV leadership within broader systems of policy making and health service provision was identified as an example of structural stigma. CONCLUSIONS: Incorporating PLHIV leadership creates a virtuous cycle, because, as PLHIV voices are heard and trusted, the case for their inclusion only gets stronger. This paper argues that a systems perspective can help to guide the most productive leverage points for intervention to tackle structural stigma and promote effective PLHIV leadership.
