The therapeutic relationship plays a crucial role in nursing care for people with mental illness. Adopting a systemic and person-centred approach that considers the individual experiences and needs of the person is paramount. However, no instruments were found in the literature designed to evaluate the nurse-patient therapeutic relationship from the perspective of a person with mental illness.

Article Synopsis
  • Diabetic ulcers are challenging to heal due to increased human neutrophil elastase (HNE) secretion and bacterial infections. The study focused on creating electrospun fibers from polycaprolactone (PCL) and polyethylene glycol (PEG) that contain elastase-targeting peptides (AAPV and WAAPV).
  • Characterization showed that WAAPV effectively inhibits HNE, and the addition of PEG helps control fiber degradation and allows for sustained peptide release over 24 hours.
  • The peptide-loaded fibers demonstrated significant antibacterial effects against certain bacteria, inhibiting growth by up to 78%, offering promising strategies for treating diabetic ulcers.

Microbial colonization and development of infections in wounds is a sign of chronicity. The prevailing approach to manage and treat these wounds involves dressings. However, these often fail in effectively addressing infections, as they struggle to both absorb exudates and maintain optimal local moisture.

New approaches to deal with the growing concern associated with antibiotic-resistant bacteria are emerging daily. Essential oils (EOs) are natural antimicrobial substances with great potential to mitigate this situation. However, their volatile nature, in their liquid-free form, has restricted their generalized application in biomedicine.

Nowadays, tissue engineering is described as an interdisciplinary field that combines engineering principles and life sciences to generate implantable devices to repair, restore and/or improve functions of injured tissues. Such devices are designed to induce the interaction and integration of tissue and cells within the implantable matrices and are manufactured to meet the appropriate physical, mechanical and physiological local demands. Biodegradable constructs based on polymeric fibers are desirable for tissue engineering due to their large surface area, interconnectivity, open pore structure, and controlled mechanical strength.
