Background And Objectives: Until recently, people in Australia with a history of injection drug use (IDU) were deferred indefinitely from donating blood. Knowledge gaps regarding policy non-compliance and the prevalence of blood donation practices amongst people who inject drugs (PWID) precluded changes to this policy. We sought to address these gaps and to estimate the additional risk to Australia's blood supply associated with changing the indefinite deferral policy to 1 or 5 years since last injecting episode.

The Avon Longitudinal Study of Parents and Children-Generation 2 (ALSPAC-G2) was set up to provide a unique multi-generational cohort. It builds on the existing ALSPAC resource, which recruited 14,541 pregnancies to women resident in the South West of England who were expected to deliver between 01/04/1991 and 31/12/1992. Those women and their partners (Generation 0; ALSPAC-G0) and their offspring (ALSPAC-G1) have been followed for the last 26 years.

Phenothiazine, owing to its ease of oxidation and modularity with respect to facile functionalization, is an attractive central chemical unit from which to construct highly reducing organic photoredox catalysts. While design improvements have been made in the community, the yield of intersystem crossing (Φ), which determines access to the long-lived triplet excited state, has yet to be systematically optimized. Herein, we explore the impacts of -aryl substituent variation on excited-state dynamics using picosecond to millisecond transient absorption and emission spectroscopies.

New Findings: What is the central question of this study? What are the metabolic impacts of high intensity functional Tabata exercise? What is the main finding and its importance? Tabata exercise with high intensity functional movements causes increases in fasted and postprandial fat oxidation the day after exercise without altering postprandial triglyceride concentrations. These results support the usage of a Tabata-style high intensity functional exercise to improve postprandial fat oxidation.

Abstract: We evaluated the effect of a high fat meal with and without prior high intensity functional exercise executed in a Tabata-style interval pattern on resting and postprandial substrate oxidation, as well as postprandial blood glucose and triglyceride concentrations.

Introduction And Aims: Heavy drinking is prevalent among undergraduate students and is linked with drinking to cope with depression motives for drinking. Drinking to cope with depression remains poorly understood given that alcohol has been shown to have adverse effects on mood when consumed at high doses. Using semi-structured qualitative interviews, the present study examined the perceived effects of alcohol on depressive symptoms as reported by undergraduate students who endorse high levels of drinking to cope with depression.

Background: Renal transplantation is the modality of choice in the treatment of end-stage kidney disease. Surgically challenging aspects of renal transplantation may include creation of vascular anastomoses where there is complex vascular anatomy. We present a paediatric case of living-related donor (LRD) renal transplantation in whom direct intravenous pressure measurement guided the management of the vascular anastomoses in the context of inferior vena cava (IVC) obstruction.

Background: Depressive symptoms show different trajectories throughout childhood and adolescence that may have different consequences for adult outcomes.

Aims: To examine trajectories of childhood depressive symptoms and their association with education and employment outcomes in early adulthood.

Method: We estimated latent trajectory classes from participants with repeated measures of self-reported depressive symptoms between 11 and 24 years of age and examined their association with two distal outcomes: university degree and those not in employment, education or training at age 24.

Variations in parenting across large populations have rarely been described. It also remains unclear which specific domains of parenting are important for which specific offspring developmental outcomes. This study describes different domains of early parenting behaviours and their genetic heritability, then determines the extent to which specific domains of parenting are associated with later offspring outcomes.

Background: Depression is a heterogeneous collection of symptoms. Prior meta-analyses using symptom sum scores have shown the Internet intervention, Deprexis, to be an efficacious treatment for depression. However, no prior research has investigated how Deprexis (or any other Internet intervention for depression) impacts specific symptoms of depression.

The human immunodeficiency virus (HIV) epidemic among adolescent girls and young women (AGYW) in sub-Saharan Africa is a critical public health problem. We assessed whether depressive symptoms in AGYW were longitudinally associated with incident HIV, and identified potential social and behavioral mediators. Data came from a randomized trial of a cash transfer conditional on school attendance among AGYW (ages 13-21 years) in rural Mpumalanga Province, South Africa, during 2011-2017.

Purpose: Maternal depression has been associated with bonding difficulties and lower maternal sensitivity in observed mother-infant interactions. However, little research has examined the impact of disordered personality traits in mothers on these outcomes. We investigated the association between disordered personality traits in mothers measured during pregnancy and postnatal (a) self-reported bonding with infant; (b) observational mother-infant interactions.

Introduction: Prenatal maternal anxiety disorders have been associated with adverse outcomes in offspring including emotional, behavioral and cognitive problems. There is limited understanding of the mechanisms underpinning these associations, although one possible candidate is an impaired mother-infant relationship. The authors investigated whether prenatal anxiety disorders were associated with poorer postpartum mother-infant relationship quality, measured by maternal self-reported bonding and observed mother-infant interactions.

Substance P (SP) regulates multiple biological processes through its high-affinity neurokinin-1 receptor (NK-1R). While the SP/NK-1R signaling axis is involved in the pathogenesis of solid cancer, the role of this signaling pathway in hematological malignancy remains unknown. Here, we demonstrate that NK-1R expression is markedly elevated in the white blood cells from acute myeloid leukemia patients and a panel of human leukemia cell lines.

Cyclin-dependent kinase 4/6 (CDK4/6) inhibitors are an established treatment in estrogen receptor-positive breast cancer and are currently in clinical development in melanoma, a tumor that exhibits high rates of CDK4 activation. We analyzed melanoma cells with acquired resistance to the CDK4/6 inhibitor palbociclib and demonstrate that the activity of PRMT5, a protein arginine methyltransferase and indirect target of CDK4, is essential for CDK4/6 inhibitor sensitivity. By indirectly suppressing PRMT5 activity, palbociclib alters the pre-mRNA splicing of MDM4, a negative regulator of p53, leading to decreased MDM4 protein expression and subsequent p53 activation.
