RELAX (REducing Levels of AnXiety): a study protocol for a parallel two-arm randomised controlled trial evaluating a web-based early intervention for pregnant women with high levels of repetitive negative thinking to prevent escalating anxiety during pregnancy and after birth.

Background: Perinatal anxiety is common: up to 40% of pregnant women and new mothers experience high levels of anxiety. Given its prevalence, interventions that are low-intensity, highly accessible and cost-efficient, and target modifiable risk factors for anxiety are needed. Repetitive negative thinking (RNT)-such as worrying about ways things will go wrong in the future or ruminating about past negative events-is a risk factor for the development of anxiety.

Modulation of diabetic wound healing using carbon monoxide gas-entrapping materials.

Diabetic wound healing is uniquely challenging to manage due to chronic inflammation and heightened microbial growth from elevated interstitial glucose. Carbon monoxide (CO), widely acknowledged as a toxic gas, is also known to provide unique therapeutic immune modulating effects. To facilitate delivery of CO, we have designed hyaluronic acid-based CO-gas-entrapping materials (CO-GEMs) for topical and prolonged gas delivery to the wound bed.

Impact of formulation on solid oxygen-entrapping materials to overcome tumor hypoxia.

Tumor hypoxia, resulting from rapid tumor growth and aberrant vascular proliferation, exacerbates tumor aggressiveness and resistance to treatments like radiation and chemotherapy. To increase tumor oxygenation, we developed solid oxygen gas-entrapping materials (O-GeMs), which were modeled after clinical brachytherapy implants, for direct tumor implantation. The objective of this study was to investigate the impact different formulations of solid O-GeMs have on the entrapment and delivery of oxygen.

Low-Cost, High-Pressure-Synthesized Oxygen-Entrapping Materials to Improve Treatment of Solid Tumors.

Tumor hypoxia drives resistance to many cancer therapies, including radiotherapy and chemotherapy. Methods that increase tumor oxygen pressures, such as hyperbaric oxygen therapy and microbubble infusion, are utilized to improve the responses to current standard-of-care therapies. However, key obstacles remain, in particular delivery of oxygen at the appropriate dose and with optimal pharmacokinetics.

Living with restraint: Reactions of nurses and lived experience workers to restrictions placed on the use of prone restraint.

Despite recent changes to mental health policy in Australia and overseas, physical restraint continues to be widely employed in mental health services. While mental health nurses have a critical role to play in supporting initiatives designed to reduce restraint, it is unclear how they feel about moves to restrict the use of prone restraint. In this qualitative study, focus group interviews were conducted with mental health nursing staff and lived experience workers (LEWs) to gain their perspectives on the use of physical restraint in general and the restrictions being placed on prone ('face down') restraint.
