No effects of acute tryptophan depletion on anxiety or mood in weight-recovered female patients with anorexia nervosaPrevious studies have suggested that individuals recovered from anorexia nervosa (AN) are characterized by increased serotonergic (5-HT) activity that might be related to elevated levels of anxiety. Assuming these traits to be also present in individuals at risk for AN, it was further hypothesized that restricting food intake might be a means to temporarily alleviate dysphoric affective states by reducing central nervous availability of tryptophan (TRP), the sole precursor of 5-HT.

Pineal morphology of the clinical high-risk state for psychosis and different psychotic disordersPineal volume reductions have been reported in schizophrenia and clinical high-risk states for the development of psychosis, supporting the role of melatonin dysregulation in the pathophysiology of psychosis.

Implications of providing wrist-hand orthoses for children with cerebral palsy: evidence from a randomised controlled trialTo investigate the effects of providing rigid wrist-hand orthoses plus usual multidisciplinary care, on reducing hand impairments in children with cerebral palsy.

The course and prognostic capability of motor difficulties in infants showing early signs of autismDelays within the motor domain are often overlooked as an early surveillance marker for autism. The present study evaluated motor difficulties and its potential as an early predictive marker for later autism likelihood in a cohort of infants showing early behavioral signs of autism aged 9-14 months. The motor domain was evaluated using the motor subscales of the Mullen Scales of Early Learning at baseline, and at a 6-month follow-up.

Associations Between Developmental Risk Profiles, Mental Disorders, and Student Absences Among Primary and Secondary Students in AustraliaThis study assessed if the association between mental disorders and higher student absences varies across different profiles of risk factors, and estimated the proportion of student absences associated with mental disorders. Data included responses from a nationally representative Australian survey of child and adolescent mental health.

The bone marrow microenvironment of pre-B acute lymphoblastic leukemia at single-cell resolutionThe bone marrow microenvironment (BMM) plays a key role in leukemia progression, but its molecular complexity in pre-B cell acute lymphoblastic leukemia (B-ALL), the most common cancer in children, remains poorly understood. To gain further insight, we used single-cell RNA sequencing to characterize the kinetics of the murine BMM during B-ALL progression.

Performance and Practicality of a Rapid Molecular Test for the Diagnosis of Strep A Pharyngitis in a Remote Australian SettingOver 5 days, 120 schoolchildren from two schools in the remote Kimberley region of Australia were screened for Strep A pharyngitis. Molecular point-of-care testing identified Strep A pharyngitis in 13/18 (72.2%) symptomatic children. The portability and feasibility of molecular point-of-care testing was highly practical for remote settings.

Narrowband UVB phototherapy reduces TNF production by B-cell subsets stimulated via TLR7 from individuals with early multiple sclerosisAt the end of a 60-day course of narrowband UVB phototherapy, administered to individuals with early multiple sclerosis, there were changes in the relative proportions of circulating B-cell subsets. This study investigated phototherapy-associated changes to cytokine responses of B cells when exposed to a TLR7 ligand.

Planning and clinical role of acute medical home care services for COVID-19: consensus position statement by the Hospital-in-the-Home Society AustralasiaDuring a pandemic when hospitals are stretched and patients need isolation, the role of hospital-in-the-home (HITH) providing acute medical care at home has never been more relevant. We aimed to define and address the challenges to acute home care services posed by the COVID-19 pandemic.

Systems Biology Methods Applied to Blood and Tissue for a Comprehensive Analysis of Immune Response to Hepatitis B Vaccine in AdultsConventional vaccine design has been based on trial-and-error approaches, which have been generally successful. However, there have been some major failures in vaccine development and we still do not have highly effective licensed vaccines for tuberculosis, HIV, respiratory syncytial virus, and other major infections of global significance. Approaches at rational vaccine design have been limited by our understanding of the immune response to vaccination at the molecular level. Tools now exist to undertake in-depth analysis using systems biology approaches, but to be fully realized, studies are required in humans with intensive blood and tissue sampling.
