RESUMO
Men who have sex with men (MSM) are disproportionately affected by HIV. Given that over 70% of MSM meet sexual partners via dating apps, such apps may be an effective platform for promoting HIV pre-exposure prophylaxis (PrEP) use. We aimed to describe preferences among MSM for PrEP advertisements displayed on dating apps. We conducted individual in-depth interviews with 16 MSM recruited from a mobile sexual health unit in Boston, Massachusetts. Two focus groups were also held: one with mobile unit staff (N = 3) and one with mobile unit users (N = 3). Content analysis was used to identify themes related to advertisement content and integration with app use. Mean participant age was 28 (SD 6.8); 37% identified as White and 63% as Latinx. 21% of interviews were conducted in Spanish. Preferences were organized around four themes: (1) relevant and relatable advertisements, (2) expansion of target audiences to promote access, (3) concise and captivating advertisements, and (4) PrEP advertisements and services as options, not obligations. MSM are supportive of receiving information about PrEP on dating apps, but feel that existing advertisements require modification to better engage viewers. Dating apps may be an underutilized tool for increasing PrEP awareness and knowledge among MSM.

BACKGROUND: Chlamydia remains the most notified bacterial sexually transmissible infection in Australia with guidelines recommending testing for re-infection at 3months post treatment. This paper aimed to determine chlamydia retesting and repeat positivity rates within 2-4months among young women in Australia, and to evaluate what factors increase or decrease the likelihood of retesting. METHODS: Chlamydia retesting rates among 16-29-year-old women were analysed from Australian Collaboration for Coordinated Enhanced Sentinel Surveillance of sexually transmissible infection and bloodborne virus (ACCESS) sentinel surveillance data (n =62 sites). Among women with at least one positive test between 1 January 2018 and 31 August 2022, retesting counts and proportions within 2-4months were calculated. Logistic regression was performed to assess factors associated with retesting within 2-4months. RESULTS: Among 8758 women who were positive before 31 August 2022 to allow time for follow up, 1423 (16.2%) were retested within 2-4months, of whom 179 (12.6%) tested positive. The odds of retesting within 2-4months were 25% lower if tested in a coronavirus disease 2019 (COVID-9) pandemic year (2020-2022) (aOR=0.75; 95% CI 0.59-0.95). Among 9140 women with a positive test before 30 November 2022, 397 (4.3%) were retested too early (within 7days to 1month) and 81 (20.4%) of those were positive. CONCLUSIONS: Chlamydia retesting rates remain low with around a sixth of women retested within 2-4months in line with guidelines. Re-infection is common with around one in eight retesting positive. An increase in retesting is required to reduce the risk of reproductive complications and onward transmission.

BACKGROUND: HIV preexposure prophylaxis (PrEP) uptake among men who have sex with men (MSM), a group disproportionately impacted by HIV, is not commensurate with need. Settings which reduce or remove barriers to accessing care are promising venues to support PrEP uptake. PrEP provision at mobile clinics represents a novel strategy to increase PrEP access; however, the acceptability and feasibility of this approach have not been well studied. METHODS: Our objective was to understand patient and staff experiences of a mobile clinic van offering PrEP and sexual health services in Boston, Massachusetts, USA. We interviewed mobile unit users and conducted focus groups with mobile unit staff and users. Data were organized using Dedoose software, and content analysis was used to identify themes of access, community, and stigma. RESULTS: Nineteen individuals (16 patients and 3 staff members) participated in interviews (N = 13) or focus groups (N = 6). All patients identified as MSM, 63% were Hispanic or Latino, and 21% of patient interviews were conducted in Spanish. Logistical and psychological convenience facilitated service use, while the community-oriented environment improved satisfaction with care. Overall, participants supported expansion of mobile unit services and recommended changes to improve access to longitudinal care. However, some barriers to PrEP persisted, including low HIV risk perception and stigma about sexual behavior. CONCLUSIONS: Mobile units can promote sexual health and PrEP uptake, particularly for populations facing social and logistical barriers to care in traditional settings.

Translated questionnaires are increasingly used in population health research. Nevertheless, translation is often not conducted with the same rigour as the process of survey development in the original language. This has serious limitations and may introduce bias in question relevance and meaning. This article describes and reflects on the process of translating a large and complex sexual and reproductive health survey from English into Simplified Chinese. We interrogated assumptions embedded in taken-for-granted translation practice to locate the sociocultural origins of these assumptions. We discuss how terminology and expression related to sexual and reproductive health may lose their conceptual or linguistic significance during translation in three different ways. Firstly, meanings can be lost in the negotiation of meanings associated with linguacultural and geographical variations of terminology. Secondly, meanings can be lost in the clash between everyday and professional sexual and reproductive health discourses. Thirdly, meanings can be lost due to the design of the source questionnaire and the intended mode of survey administration. We discuss ways to help overcome the unavoidable translation challenges that arise in the process of translating English sexual and reproductive health surveys for migrants from non-English speaking backgrounds.

BACKGROUND: Patients with germline/somatic BRCA1/BRCA2 mutations (g/sBRCA1/2) comprise a distinct biologic subgroup of pancreas ductal adenocarcinoma (PDAC). METHODS: Institutional databases were queried to identify patients who had PDAC with g/sBRCA1/2. Demographics, clinicopathologic details, genomic data (annotation sBRCA1/2 according to a precision oncology knowledge base for somatic mutations), zygosity, and outcomes were abstracted. Overall survival (OS) was estimated using the Kaplan-Meier method. RESULTS: In total, 136 patients with g/sBRCA1/2 were identified between January 2011 and June 2020. Germline BRCA1/2 (gBRCA1/2) mutation was identified in 116 patients (85%). Oncogenic somatic BRCA1/2 (sBRCA1/2) mutation was present in 20 patients (15%). Seventy-seven patients had biallelic BRCA1/2 mutations (83%), and 16 (17%) had heterozygous mutations. Sixty-five patients with stage IV disease received frontline platinum therapy, and 52 (80%) had a partial response. The median OS for entire cohort was 27.6 months (95% CI, 24.9-34.5 months), and the median OS for patients who had stage IV disease was 23 months (95% CI, 19-26 months). Seventy-one patients received a poly(adenosine diphosphate ribose) polymerase (PARP) inhibitor (PARPi), and 52 received PARPi monotherapy. For maintenance PARPi, 10 patients (36%) had a partial response, 12 (43%) had stable disease, and 6 (21%) had progression of disease as their best response. Six patients (21%) received maintenance PARPi for >2 years. For those with stage IV disease who received frontline platinum, the median OS was 26 months (95% CI, 20-52 months) for biallelic patients (n = 39) and 8.66 months (95% CI, 6.2 months to not reached) for heterozygous patients (n = 4). The median OS for those who received PARPi therapy was 26.5 months (95% CI, 24-53 months) for biallelic patients (n = 25) and 8.66 months (95% CI, 7.23 months to not reached) for heterozygous patients (n = 2). CONCLUSIONS: g/sBRCA1/2 mutations did not appear to have different actionable utility. Platinum and PARPi therapies offer therapeutic benefit, and very durable outcomes are observed in a subset of patients who have g/sBRCA1/2 mutations with biallelic status.

BACKGROUND: /Objectives: Pancreatic adenocarcinoma (PDAC) metastatic to the leptomeninges is a rare and lethal event. Leptomeningeal disease (LMD) research is limited in PDAC, and insights into clinical descriptors, possible disease predictors, and treatment strategies is necessitated. METHODS: Memorial Sloan Kettering databases were queried with Institutional Review Board approval to identify patients with LMD and PDAC treated between January 2000 and June 2020. Medical record review was used to abstract clinical, genomic, pathologic, and radiographic data. Overall survival was calculated from date of PDAC diagnosis to date of death. Previously published literature on LMD from PDAC was reviewed. RESULTS: Four patients with LMD from PDAC were identified, two males and two females. Age at diagnosis ranged from 57 to 68 years. All four patients had predominant lung metastasis and a relatively low burden of intra-abdominal disease. Somatic testing indicated alterations typical of PDAC and no PDAC defining pathogenic germline mutations were identified. An extended clinical course prior to LMD diagnosis was observed in all patients, ranging from 16 to 148 months. Upon diagnosis of LMD, three patients elected for supportive care and one patient received a limited course of craniospinal radiation. The median survival following diagnosis of LMD was 1.6 months (range 0.5-2.8 months). CONCLUSIONS: LMD from PDAC is a rare occurrence that may be more frequent in patients with lung metastasis and/or a more indolent clinical course. Following diagnosis of LMD, prognosis is poor, and survival is short. New treatment strategies for this manifestation of PDAC are needed.

Videoconferencing focus groups have emerged as a popular method for collecting qualitative data. However, its use in sexual and reproductive health research is still very much in its infancy. Based on participants' feedback and researchers' reflections on using videoconferencing focus groups to collect sexual and reproductive health data with 39 heterosexual and non-heterosexual Chinese im/migrants in Australia, we discuss some of the key lessons learned, and considerations involved in shifting from face-to-face to online focus groups. Overall, videoconferencing focus groups appeared to be a highly feasible and acceptable way to discuss "sensitive" topics with Chinese im/migrants. Importantly, researchers need to be both creative and reflexive during the research process and must not forget that the success of a study lies not only in troubleshooting technical issues but also in cultivating and maintaining a trusting relationship with research participants.

In September 2018, monkeypox virus was transmitted from a patient to a healthcare worker in the United Kingdom. Transmission was probably through contact with contaminated bedding. Infection control precautions for contacts (vaccination, daily monitoring, staying home from work) were implemented. Of 134 potential contacts, 4 became ill; all patients survived.

BACKGROUND: In recent years, gonorrhea notifications have increased in women in Australia and other countries. We measured trends over time and risk factors among Australian Aboriginal and Torres Strait Islander ("Aboriginal") and non-Aboriginal women. METHODS: We conducted a cross-sectional analysis of data from 41 sexual health clinics. Gonorrhea positivity at each patient's first visit (first-test positivity) during the period 2009 to 2016 was calculated. Univariate and multivariate analyses assessed risk factors for first-test positivity in Aboriginal and non-Aboriginal women. RESULTS: Gonorrhea positivity decreased among Aboriginal women (7.1% in 2009 to 5.2% in 2016, P < 0.001) and increased among non-Aboriginal women (0.6%-2.9%, P < 0.001). Among Aboriginal women, first-test positivity was independently associated with living in a regional or remote area (adjusted odds ratio [aOR], 4.29; 95% confidence interval [CI], 2.52-7.31; P < 0.01) and chlamydia infection (aOR, 4.20; 95% CI,3.22-5.47; P < 0.01). Among non-Aboriginal women, first-test positivity was independently associated with greater socioeconomic disadvantage (second quartile: aOR, 1.68 [95% CI, 1.31-2.16; P < 0.01]; third quartile: aOR, 1.54 [95% CI, 1.25-1.89; P < 0.01]) compared with least disadvantaged quartile: recent sex work (aOR, 1.69; 95% CI, 1.37-2.08; P < 0.01), recent injecting drug use (aOR, 1.85; 95% CI, 1.34-2.57; P < 0.01), and chlamydia infection (aOR, 2.35; 95% CI, 1.90-2.91; P < 0.01). For non-Aboriginal women, being aged 16 to 19 years (aOR, 0.62; 95% CI, 0.49-0.80; P < 0.01) compared with those ≥30 years was a protective factor. CONCLUSIONS: These findings highlight 2 different epidemics and risk factors for Aboriginal and non-Aboriginal women, which can inform appropriate health promotion and clinical strategies.

OBJECTIVES: To determine trends in and predictors of early treatment for people newly diagnosed with human immunodeficiency virus (HIV) infection in Australia. DESIGN, SETTING: Retrospective cohort analysis of routinely collected longitudinal data from 44 sexual health clinics participating in the Australian Collaboration for Coordinated Enhanced Sentinel Surveillance (ACCESS) program. PARTICIPANTS: Patients diagnosed with HIV infections, January 2004 - June 2015. MAIN OUTCOME MEASURES: Commencement of antiretroviral therapy within 6 months of HIV diagnosis (early treatment); demographic, clinical, and risk group characteristics of patients associated with early treatment; trends in early treatment, by CD4+ cell count at diagnosis. RESULTS: 917 people were diagnosed with HIV infections, their median age was 34 years (interquartile range [IQR]: 27-43 years), and 841 (92%) were men; the median CD4+ cell count at diagnosis was 510 cells/µL (IQR, 350-674 cells/µL). The proportion of patients who received early treatment increased from 17% (15 patients) in 2004-06 to 20% (34 patients) in 2007-09, 34% (95 patients) in 2010-12, and 53% (197 patients) in 2013-15 (trend, P < 0.001). The probability of early treatment, which increased with time, was higher for patients with lower CD4+ cell counts and higher viral loads at diagnosis. CONCLUSIONS: The proportion of people newly diagnosed with HIV in sexual health clinics in Australia who received treatment within 6 months of diagnosis increased from 17% to 53% during 2004-2015, reflecting changes in the CD4+ cell count threshold in treatment guidelines. Nevertheless, further strategies are needed to maximise the benefits of treatment to prevent viral transmission and morbidity.

BACKGROUND: Tenofovir disoproxil fumarate (TDF) is widely used in the management of HIV-infection, but has been associated with renal impairment in a small proportion of patients. Tenofovir alafenamide (TAF), a novel prodrug of tenofovir, causes less renal impairment and can improve renal function in patients switched from TDF. The factors which predict improved renal function in patients switching from TDF to TAF have yet to be described. AIM: To determine which patient factors are associated with an improvement in renal function following the switch from a TDF- to a TAF-based HIV antiretroviral regimen. METHODS: A retrospective analysis was performed of a cohort from a publicly funded sexual health clinic in Sydney, Australia. All HIV-positive clinic patients switched from a TDF- to TAF-containing regimen between January 2016 and August 2018 were eligible for inclusion. Laboratory results were obtained from patients' electronic medical records. The statistical significance of differences between pre- and post-switch means was determined by paired t-tests, adjusted for baseline values, and associations between continuous variables by univariate linear regression. RESULTS: 79 patients met inclusion criteria. The majority were male (89%), with a median age of 44 years (IQR: 34.5 to 53). Patients had a mean pre-switch estimated glomerular filtration rate (eGFR) of 95 ± 2 mL/min/1.73 m2, and there was no significant change post-switch (p = 0.062). Pre-switch eGFR was a significant predictor of the magnitude of eGFR change after the switch (p < 0.001), but there was no significant association with age (p = 0.189), cumulative TDF exposure (p = 0.454) or baseline urinary protein to creatinine ratio (p = 0.814). CONCLUSION: While there was no significant difference in mean eGFR, in patients switched from TDF to TAF, baseline eGFR was a significant predictor of the change in eGFR. This suggests that patients on TDF with poorer baseline renal function would benefit more from switching to TAF. Further study to explore this association is warranted.

BACKGROUND: People with HIV (PLHIV) are aging, and 20% are at risk of developing a neurological complication known as HIV-associated neurocognitive disorder (HAND). Signs and symptoms of HAND may be subtle; however, treatment can improve clinical outcomes. OBJECTIVE: The aim of the study was to identify and agree on a risk assessment and monitoring process for the regular review of patients at risk of HAND. METHODS: Between March and September 2017, 25 experts from four community healthcare services participated in three rounds of a modified Delphi study to reach consensus on the items, monitoring period, and format of assessment tools to identify risk of HAND in PLHIV in the community. RESULTS: More than 80% consensus was reached at all three Delphi rounds. A flow chart, an initial assessment, and an annual monitoring tool were developed for an ongoing assessment of risk of developing HAND. CONCLUSION: Twenty percent of PLHIV may develop HAND, a treatable condition. The use of a modified Delphi method led to the successful development of two risk assessment tools to identify those at risk of HAND. The initial assessment tool may be used as a precursor to formal assessment by medical and nursing staff, whereas the annual monitoring tool may assist community-based health professionals in their ongoing assessment of risk of HAND in PLHIV, facilitating early formal medical review for this condition.

BACKGROUND: Female sex workers in Australia have achieved some of the lowest documented prevalences of human immunodeficiency virus (HIV) and other sexually transmissible infections globally but rates overall are increasing in Australia and warrant closer investigation. METHODS: We constructed a retrospective cohort using repeat testing data extracted from a network of 42 sexual health clinics. Poisson and Cox regression were used to determined trends in incidence and risk factors for HIV, chlamydia, gonorrhoea, and infectious syphilis among female sex workers. RESULTS: From 2009 to 2015, 18,475 women reporting sex work attended a participating service. The overall incidence of urogenital chlamydia was 7.7/100 person years (PY), declining by 38% from 2009 to 2013 before increasing by 43% to 2015 (P < 0.001); anorectal chlamydia incidence was 0.6/100 PY, and pharyngeal was 1.9/100 PY, which increased significantly during the study period (P < 0.001, both). For gonorrhoea, the urogenital incidence was 1.4/100 PY, anorectal incidence was 0.3/100 PY, P < 0.001), and 3.6/100 PY for pharyngeal; urogenital incidence doubled during the study period, anorectal increased fivefold, and pharyngeal more than tripled (P < 0.001, all). Incidence of infectious syphilis was 0.4/100 PY, which remained stable from 2009 to 2015 (P = 0.09). There were seven incident infections of HIV among female sex workers (0.1/100 PY). Inconsistent condom use with private partners, higher number of private partner numbers, recent injecting drug use, younger age, and country of birth variously predicted sexually transmissible infections among female sex workers. CONCLUSIONS: Although infectious syphilis and HIV remain uncommon in female sex workers attending Australian sexual health clinics, the increasing incidence of gonorrhoea across anatomical sites and increasing chlamydia after a period of decline demands enhanced health promotion initiatives.

We assessed trends in HIV testing outcomes during a period of clinic-based initiatives introduced to increase HIV testing among gay and bisexual men (GBM) attending sexual health clinics (SHCs) in New South Wales (NSW). A cohort of 25,487 HIV-negative GBM attending 32 SHCs in NSW (2009-2015) was classified into six sub-groups each year based on client-type (new/existing), risk-status (low/high-risk), and any recent HIV testing. Poisson regression methods were used to assess HIV testing outcomes in sub-groups of GBM. HIV testing outcomes and the sub-groups with greatest statistically significant annual increases were: individuals attending (26% in high-risk existing clients with recent testing); testing uptake (4% in low-risk existing clients with no recent testing); testing frequency (6% in low-risk existing clients with no recent testing and 5% in high-risk existing clients with recent testing); and total tests (31% in high-risk existing clients with recent testing). High-risk existing clients with recent testing had a 13% annual increase in the proportional contribution to total tests. Our findings show improved targeting of testing to high-risk GBM at NSW SHCs. The clinic-based initiatives should be considered for translation to other similar settings.

This study aimed to determine whether people living with HIV (PLHIV) are concerned about HIV associated neurocognitive disorder (HAND) and would find information and resources for HAND beneficial. An online survey focusing on the experience of HAND was distributed via the website of Positive Life New South Wales: a peak peer-support non-government organization in Australia. Of 126 respondents, 94 (74%) had heard of HAND, 52/94 (55%) had experienced concerns and of these, 48/52 (92%) felt anxiety about discussing the subject. Of those who had experienced concerns, 30/52 (58%) had spoken to someone about these concerns and 23/30 (77%) had received a positive response. Across the entire sample, 74 (59%) had noticed symptoms of cognitive decline in themselves and/or others. Respondents who noted a decrease in their ability to organize were on average five years older than those who had not noticed a decline (p = 0.012, effect size -.54). Forty-nine (39%) indicated that they would like guidance to initiate discussion about HAND with their doctor, caregiver or other PLHIV. The survey findings suggest that increasing awareness of HAND among PLHIV and their caregivers, and providing resources to facilitate discussion about HAND may assist to reduce concerns among PLHIV and enhance the effectiveness of clinical review.

In 2017, Public Health England South East Health Protection Team (HPT) were involved in the management of an outbreak of Mycobacterium bovis (the causative agent of bovine tuberculosis) in a pack of working foxhounds. This paper summarises the actions taken by the team in managing the public health aspects of the outbreak, and lessons learned to improve the management of future potential outbreaks. A literature search was conducted to identify relevant publications on M. bovis. Clinical notes from the Public Health England (PHE) health protection database were reviewed and key points extracted. Animal and public health stakeholders involved in the management of the situation provided further evidence through unstructured interviews and personal communications. The PHE South East team initially provided 'inform and advise' letters to human contacts whilst awaiting laboratory confirmation to identify the infectious agent. Once M. bovis had been confirmed in the hounds, an in-depth risk assessment was conducted, and contacts were stratified in to risk pools. Eleven out of 20 exposed persons with the greatest risk of exposure were recommended to attend TB screening and one tested positive, but had no evidence of active TB infection. The number of human contacts working with foxhound packs can be large and varied. HPTs should undertake a comprehensive risk assessment of all potential routes of exposure, involve all other relevant stakeholders from an early stage and undertake regular risk assessments. Current guidance should be revised to account for the unique risks to human health posed by exposure to infected working dogs.
RESUMO
The Anthropocene is marked by an unprecedented homogenisation of the world's biota, confronting species that never co-occurred during their evolutionary histories. Interactions established in these novel communities may affect ecosystem functioning; however, most research has focused on the impacts of a minority of aggressive invasive species, while changes inflicted by a less conspicuous majority of non-invasive alien species on community structure are still poorly understood. This information is critical to guide conservation strategies, and instrumental to advance ecological theory, particularly to understand how non-native species integrate in recipient communities and affect the interactions of native species. We evaluated how the structure of 50 published pollination networks changes with the proportion of alien plant species and found that network structure is largely unaffected. Although some communities were heavily invaded, the proportion of alien plant species was relatively low (mean = 10%; max. = 38%). We further characterized the pollination network in a botanic garden with a plant community dominated by non-invasive alien species (85%). We show that the structure of this novel community is also not markedly different from native-dominated communities. Plant-pollinator interactions revealed no obvious differences regarding plant origin (native vs. alien) or the native bioregion of the introduced plants. This overall similarity between native and alien plants is likely driven by the contrasting patterns of invasive plants (promoting generalism), and non-invasive aliens, suggested here to promote specialization.

BACKGROUND: Individuals aged 13-24 years undergo vast physical, cognitive, social and psychological changes. Australian data regarding clinical outcomes of those diagnosed with HIV in this age are sparse. AIM: We aimed to describe demographic factors, virologic and clinical outcomes of individuals aged 13-24 years diagnosed with human immunodeficiency virus (HIV). METHODS: Patients diagnosed with HIV after 1997 in the Australian HIV Observational Database were divided into young adults, diagnosed at age <25 years (n = 223), and older adults (n = 1957). Demographic and clinical factors were compared between groups. RESULTS: Young adults had a median age at diagnosis of 22 years (inter quartile range (IQR) 20-24) and median age at treatment initiation of 24 years (IQR 22-26). They were more likely to be female than the older cohort (21.1 vs 10.8%; P < 0.001). Men who have sex with men was the most common exposure category in both groups. CD4 count at diagnosis was significantly higher in younger than older adults (median 460 vs 400 cells/mm3 , P = 0.006), whereas HIV viral load at diagnosis was lower (35 400 vs 61 659 copies/mL, P = 0.011). The rate of loss to follow up (LTFU) was higher in young adults (8.0 vs 4.3 per 100PY, P < 0.001). Young adults were more likely to have a treatment interruption compared to older adults (5.3 vs 4.0 per 100PY, P = 0.039). Rates of treatment switch, time to treatment change, and CD4 and viral load responses to treatment were similar between groups. CONCLUSIONS: Young adults were diagnosed with HIV at higher CD4 counts and lower viral loads than their older counterparts. LTFU and treatment interruption were more common highlighting the need for extra efforts directed towards retention in care and education regarding the risks of treatment interruptions.

AIM: The aim of the present study was to examine data from the Australian HIV Observational Database (AHOD), and firstly, to describe the incidence of chronic kidney disease (CKD) and the rate of loss of renal function in HIV-infected individuals living in Australia, and then to examine the risk factors contributing to CKD in this population. METHODS: AHOD patients over 18 years of age were eligible if they had at least two serum creatinine measurements from 1 April 2008 until 31 March 2016 and an initial estimated glomerular filtration rate (eGFR) greater than 60 mL/min per 1.73 m3 . Cox proportional hazards models were used to assess risk factors for CKD, which included key patient demographic data and antiretroviral therapy (ART) exposure. RESULTS: Of 1924 patients included in the analysis between April 2008 and March 2016, 81 (4.2%) developed CKD (confirmed eGFR of less than 60 mL/min per 1.73 m3 through two consecutive eGFR measurements at least 3 months apart). Of the examined risk factors, baseline age, baseline eGFR, and the route of HIV acquisition were statistically significant predictors of development of CKD. ART exposure, viral hepatitis co-infection, high viral load and low CD4 lymphocyte count were not found to be significant risk factors for CKD. CONCLUSION: This is the first study to investigate the risk factors for development of CKD among Australian HIV-infected patients using cohort data. It highlights the need for awareness of renal risk factors, particularly among older patients or in those with pre-existing renal dysfunction. Further research is required to explore the discrepancy between patients who have acquired HIV through different means of exposure.
