The shortage of adequately trained healthcare providers (HCPs) able to treat adults who have experienced childhood interpersonal trauma (CIT) is a pressing concern. This study explored HCPs' training needs for a trauma-focused psychoeducational group intervention and the potential barriers and facilitators to accessing such training. Three 1-hour focus group sessions were conducted with HCPs ( = 17) from two urban and one rural community healthcare organization serving diverse populations in Ontario, Canada, including under-housed people, women struggling with mental health and addiction, and LGBTQ+ populations.

A major hallmark of cancer is the reprogramming of cellular metabolism from oxidative phosphorylation (OXPHOS) to glycolysis, a phenomenon known as the Warburg effect. To sustain high rates of glycolysis, cancer cells overexpress GLUT transporters and glycolytic enzymes, allowing for the enhanced uptake and consumption of glucose. The Warburg effect may be exploited in the treatment of cancer; certain epimers and derivatives of glucose can enter cancer cells and inhibit glycolytic enzymes, stunting metabolism and causing cell death.

Background: Adults with mental health symptoms stemming from childhood interpersonal trauma require specialized trauma-focused psychological interventions. Limitations in accessing treatment interventions for this population necessitate innovative solutions. This study explored the feasibility of a protocol for a blended e-health psychoeducational treatment intervention for this population called the Trauma PORTAL (Providing Online tRauma Therapy using an Asynchronous Learning platform), combining asynchronous online modules and weekly live virtual group sessions.

Background: The long-term mental and physical health implications of childhood interpersonal trauma on adult survivors is immense, however, there is a lack of available trauma-focused treatment services that are widely accessible. This study, utilizing a user-centered design process, sought feedback on the initial design and development of a novel, self-paced psychoeducation and skills-based treatment intervention for this population.

Aims: To explore the views and perspectives of adult survivors of childhood interpersonal trauma on the first two modules of an asynchronous trauma-focused treatment program.

In acute skin injury, healing is impaired by the excessive release of reactive oxygen species (ROS). Melanin, an efficient scavenger of radical species in the skin, performs a key role in ROS scavenging in response to UV radiation and is upregulated in response to toxic insult. In a chemical injury model in mice, we demonstrate that the topical application of synthetic melanin particles (SMPs) significantly decreases edema, reduces eschar detachment time, and increases the rate of wound area reduction compared to vehicle controls.
