ObjectivesRates of youth suicide in Australian Indigenous communities are 4 times the national youth average and demand innovative interventions. Historical and persistent disadvantage is coupled with multiple barriers to help seeking. Mobile phone applications offer the opportunity to deliver therapeutic interventions directly to individuals in remote communities. The pilot study aimed to evaluate the effectiveness of a self-help mobile app (ibobbly) targeting suicidal ideation, depression, psychological distress and impulsivity among Indigenous youth in remote Australia.SettingRemote and very remote communities in the Kimberley region of North Western Australia.ParticipantsIndigenous Australians aged 18–35 years.Interventions61 participants were recruited and randomised to receive either an app (ibobbly) which delivered acceptance-based therapy over 6 weeks or were waitlisted for 6 weeks and then received the app for the following 6 weeks.Primary and secondary outcome measuresThe primary outcome was the Depressive Symptom Inventory—Suicidality Subscale (DSI-SS) to identify the frequency and intensity of suicidal ideation in the previous weeks. Secondary outcomes were the Patient Health Questionnaire 9 (PHQ-9), The Kessler Psychological Distress Scale (K10) and the Barratt Impulsivity Scale (BIS-11).ResultsAlthough preintervention and postintervention changes on the (DSI-SS) were significant in the ibobbly arm (t=2.40; df=58.1; p=0.0195), these differences were not significant compared with the waitlist arm (t=1.05; df=57.8; p=0.2962). However, participants in the ibobbly group showed substantial and statistically significant reductions in PHQ-9 and K10 scores compared with waitlist. No differences were observed in impulsivity. Waitlist participants improved after 6 weeks of app use.ConclusionsApps for suicide prevention reduce distress and depression but do not show significant reductions on suicide ideation or impulsivity. A feasible and acceptable means of lowering symptoms for mental health disorders in remote communities is via appropriately designed self-help apps.Trial registration numberACTRN12613000104752.
We modeled global time trends in median CD4 cell counts at combination antiretroviral therapy initiation in human immunodeficiency virus–infected adults. These counts have increased in all country income groups since 2002 but generally remained below 350/μL in 2015.
Cancer burden is increasing in kidney transplant recipients, but differences in mortality compared to the general population remain unclear. We sought to compare cancer mortality in paediatric and adult kidney transplant recipients with the general population and describe any differences, by site, age and sex, country and over time. We included kidney transplant recipients from the Australian and New Zealand Dialysis and Transplantation Registry, 1980–2013. Date of death and underlying cause of death were ascertained by data‐linkage and classified using ICD10AM codes. Indirect standardisation was used to estimate standardised mortality ratios (SMR). There were 5,284 deaths in 17,628 kidney transplant recipients over 175,084 person‐years of observation, including 1,061 (20%) cancer deaths. Relative cancer mortality was higher than the general population for all‐site (SMR 2.9, 95% CI 2.7–3.1) cancer and highest for nonmelanoma skin cancer (SMR 50.9, 95% CI 43.5–59.6) and lymphoma (SMR 42.2, 95% CI 35.3–50.5). Relative cancer mortality decreased with increasing age in men (p < 0.001) and women (p = 0.001) but never reached parity with the general population. Relative mortality did not change with age for skin and lip, or colorectal cancers (p‐value >0.1). Only relative colorectal cancer mortality increased over time (p = 0.002). Our study shows cancer mortality in kidney transplant recipients was higher than expected in the general population. The magnitude of excess mortality varied by cancer site, age and sex. Further evidence is needed to identify whether this variation is due to differences at diagnosis or access and effectiveness of cancer treatments in this population.
Background Antiretroviral treatment (ART) for HIV-positive patients has expanded rapidly in Asia over the last ten years. Our study aimed to describe the time trends and risk factors for overall survival in patients receiving first-line ART in Asia. Methods We included HIV-positive adult patients who initiated ART between 2003–2013 (n=16 546), from seven sites across six Asia-Pacific countries. Patient follow-up was to May 2014. We compared survival for each country and overall by time period of ART initiation using Kaplan-Meier curves. Factors associated with mortality were assessed using Cox regression, stratified by site. We also summarized first-line ART regimens, CD4 count at ART initiation, and CD4 and HIV viral load testing frequencies. Results There were 880 deaths observed over 54 532 person-years of follow-up, a crude rate of 1.61 (1.51, 1.72) per 100 person-years. Survival significantly improved in more recent years of ART initiation. The survival probabilities at 4 years follow-up for those initiating ART in 2003–05 was 92.1%, 2006–09 was 94.3% and 2010–2013 was 94.5% (p<0.001). Factors associated with higher mortality risk included initiating ART in earlier time periods, older age, male sex, injecting drug use as HIV exposure and lower pre-ART CD4 count. Concurrent with improved survival was increased tenofovir use, ART initiation at higher CD4 counts, and greater monitoring of CD4 and HIV viral load. Conclusions Our results suggest that HIV-positive patients from Asia have improved survival in more recent years of ART initiation. This is likely a consequence of improvements in treatment and, patient management and monitoring over time.
Objective To estimate the prevalence and incidence of human immunodeficiency virus (HIV), hepatitis C virus (HCV), and hepatitis B virus (HBV) among people at increased risk of infection in Australia; to estimate the residual risk of infection among potential solid organ donors in these groups when their antibody and nucleic acid test results are negative. Study design Systematic review and meta‐analysis of reports of the incidence and prevalence of HIV, HCV, and HBV in groups at increased risk of infection in Australia. Data sources MEDLINE, government and agency reports, Australasian Society for HIV, Viral Hepatitis and Sexual Health Medicine conference abstracts, the Australian New Zealand Clinical Trial Registry, and National Health and Medical Research Council grants published 1 January 2000 – 14 February 2019; personal communications. Data synthesis Residual risk of HIV infection was highest among men who have sex with men (4.8 [95% CI, 2.7–6.9] per 10 000 antibody‐negative persons; 1.5 [95% CI, 0.9–2.2] per 10 000 persons who are both antibody‐ and nucleic acid‐negative). Residual risk of HCV infection was highest among injecting drug users (289 [95% CI, 191–385] per 10 000 antibody‐negative persons; 20.9 [95% CI, 13.8–28.0] per 10 000 antibody‐ and nucleic acid‐negative persons). Residual risk for HBV infection was highest among injecting drug users (98.6 [95% CI, 36.4–213] per 10 000 antibody‐negative people; 49.4 [95% CI, 18.2–107] per 10 000 persons who were also nucleic acid‐negative). Conclusions Absolute risks of window period viral infections are low in people from Australian groups at increased risk but with negative viral test results. Accepting organ donations by people at increased risk of infection but with negative viral test results could be considered as a strategy for expanding the donor pool.
