To report on the design and results of an innovative nurse practitioner (NP)-led specialist primary care service for children facing housing instability.

During 2017–2018, children aged 0–14 years represented 23% of the total population receiving support from specialist homeless services in Australia. The impact of housing instability on Australian children is considerable, resulting in disengagement from social institutions including health and education, and poorer physical and mental health outcomes across the lifespan. Current services fail to adequately address health and educational needs of children facing housing insecurity. Research identifies similar circumstances for children in other high-income countries. This paper outlines the design, and reports on results of, an innovative NP-led primary care service for children facing housing instability introduced into three not-for-profit faith-based services in one Australian state.

Between 2019 and 2021, 66 children of parents experiencing housing instability received standardized health assessment and referral where appropriate by a NP. Data from the standardized tool, such as condition and severity, were recorded to determine common conditions. In addition, comprehensive case notes recorded by the NP were used to understand potential causes of conditions, and referral needs, including potential barriers.

The 66 children assessed were aged between 7 weeks to 16 years. Developmental delay, low immunization rates, and dental caries were the most common conditions identified. Access to appropriate services was inhibited by cost, disengagement, and COVID-19.

Given their advanced skills and knowledge, embedding NPs in specialist homeless services is advantageous to help vulnerable children.

Better knowledge about childhood trauma as a risk factor for psychiatric disorders in young people could help strengthen the timeliness and effectiveness of prevention and treatment efforts.

To estimate the prevalence and risk of psychiatric disorders in young people following exposure to childhood trauma, including interpersonal violence.

This prospective cohort study followed 8199 adolescents (age range 12–20 years) over 13–15 years, into young adulthood (age range 25–35 years). Data about childhood trauma exposure from adolescents participating in the Trøndelag Health Study (HUNT, 2006–2008) were linked to data about subsequent development of psychiatric disorders from the Norwegian Patient Registry (2008–2021).

One in four (24.3%) adolescents were diagnosed with a psychiatric disorder by young adulthood. Regression analyses showed consistent and significant relationships between childhood exposure to both interpersonal violence and other potentially traumatic events, and subsequent psychiatric disorders and psychiatric comorbidity. The highest estimates were observed for childhood exposure to two or more types of interpersonal violence (polyvictimisation), and development of psychotic disorders (odds ratio 3.41, 95% CI 1.93–5.72), stress and adjustment disorders (odds ratio 4.20, 95% CI 3.05–5.71), personality disorders (odds ratio 3.98, 95% CI 2.70–5.76), alcohol-related disorders (odds ratio 3.28, 95% CI 2.06–5.04) and drug-related disorders (odds ratio 4.67, 95% CI 2.87–7.33).

These findings emphasise the importance of integrating knowledge about childhood trauma as a potent risk factor for psychopathology into the planning and implementation of services for children, adolescents and young adults.

To determine the effects of the non-classic psychedelic, ibogaine, on cognitive functioning. Ibogaine is an indole alkaloid derived from the Tabernanthe Iboga plant family, indigenous to Africa, and traditionally used in spiritual and healing ceremonies. Ibogaine has primarily been studied with respect to its clinical efficacy in reducing substance addiction. There are, however, indications that it also may enhance recovery from traumatic experiences. Ibogaine is a Schedule 1 substance in the USA.

Participants were U.S. Special Operations Veterans who had independently and voluntarily referred themselves for an ibogaine retreat at a specialized clinic outside the USA prior to learning about this observational study. After meeting rigorous screening requirements, 30 participants were enrolled, all endorsing histories of combat and repeated blast exposure, as well as traumatic brain injury. Participants were seen in person pre-treatment, post-treatment, and one-month post-treatment for neuropsychological testing, neuroimaging, and collection of clinical outcome measures. All 30 participants were seen pre- and post-treatment, of whom 27 were also able to return one-month post-treatment.

The neuropsychological battery included the the Hopkins Verbal Learning Test (HVLT), the Brief Visuospatial Memory Test - Revised (BVMT-R), the Wechsler Adult Intelligence Scale - Fourth Edition (WAIS-IV) Working Memory Index (Digit Span and Arithmetic) and Processing Speed Index (Symbol Search and Coding), and the Delis-Kaplan Executive Function System (D-KEFS) tests of Verbal Fluency (VF), Trail Making (TMT), Color Word (CW), and Tower Test (TT). For repeated measures, alternate forms were used whenever possible.

Repeated-measures ANOVA revealed significant effects of time, with post-treatment improvements across multiple measures including processing speed (WAIS-IV PSI; F(2,25) = 26.957, p < .001), executive functions (CW Conditions 3 and 4: F(1.445,25) = 11.383, p < .001 and F(1.381,25) = 7.687, p = .004, respectively), verbal fluency (VF Condition 3 correct and accuracy: F(2,25) = 6.419, p = .003 and F(2,25) = 153.076, p < .001, respectively), and verbal learning (HVLT Total Recall (alternate forms used at each time point): F(1.563,23) = 6.958, p = .004). Score progression graphs are presented. Performance on all other cognitive measures did not significantly change following treatment.

To our knowledge, this is the first prospective study examining neuropsychological test performance following ibogaine use at post-treatment and one-month post-treatment time points. Our results indicated that several cognitive domains improved either post-treatment or one-month post-ibogaine treatment, suggesting ibogaine’s therapeutic potential for cognition in the context of traumatic brain injury and mood disorders. Potential explanations include neuroplastic changes, reduction of PTSD and mood-related effects on cognitive functioning, and practice effects. While we found no evidence of negative cognitive consequences for up to one-month post-single-ibogaine treatment, further study of this substance is necessary to clarify its clinical utility and safety parameters.
