The integration of genomics into public health and medicine is happening at a faster rate than the accrual of the capabilities necessary to ensure the equitable, global distribution of its clinical benefits. Uneven access to genetic testing and follow-up care, unequal distribution of the resources required to access and participate in research, and underrepresentation of some descent groups in genetic and clinical datasets (and thus uncertain genetic results for some patients) are just some of the reasons to center justice in genomics. A more just genomics is an imperative rooted in the ethical obligations incurred by a publicly funded science that is reliant on human data.

Background: Subanesthetic doses of (R,S)-ketamine (ketamine) have demonstrated rapid and robust antidepressant effects in individuals with depression. However, individual variability in response to ketamine exists, and current biomarkers of ketamine treatment response are not entirely understood. Preclinical evidence suggests a link between hypothalamic-pituitary-adrenal (HPA) axis activation, a determinant of the stress response system, and ketamine's efficacy in stressed mice exhibiting enhanced antidepressant responses.

Purpose: Patient experiences of brachytherapy for locally advanced cervical cancer (LACC) are widely variable, with reports of difficult and traumatic experiences and aspects of care requiring improvement. The aim of this study was to develop patient care recommendations and consult with key stakeholders to review, refine and prioritise recommendations.

Methods: Phase 1: Patient care recommendations were developed from qualitative exploratory study data.

Background: Blunt abdominal trauma (BAT) is a significant contributor to pediatric mortality, often causing liver and spleen injuries. Contrast-enhanced computed tomography (CT), the gold standard for diagnosing solid organ injury, poses radiation risks to children. Contrast-enhanced ultrasound (CEUS) may be a promising alternative imaging modality.
