Background: The existing literature on sexuality and intimacy in residential care tends to focus on either the question of rights, or the value of autonomy. Where the literature does reference values other than autonomy, such values are considered in the context of being a guide to whether or not a resident is autonomous, rather than being important values in their own right.

Objective: This paper draws on qualitative data gathered as part of a larger study in order to inform practice on how care workers respond to intimacy issues that arise with residents with dementia and to inform a general ethics of sex and sexuality, demonstrating that an approach which permits value pluralism can be appropriate in certain contexts.

Background: Bronchiectasis is a chronic lung condition frequently associated with nontuberculous mycobacteria pulmonary (NTM) disease. Persons with these conditions are at increased risk of mortality. Patient reported outcome (PRO) instruments and the 6-minute walk test (6MWT) have been shown to predict mortality for several lung conditions, but these measures have not been fully evaluated for bronchiectasis and NTM.

Background: Despite evidence that clinical outcomes for patients treated with peritoneal dialysis (PD) or home haemodialysis are better than for patients treated with conventional satellite or hospital-based haemodialysis, rates of home-based dialysis therapies world-wide remain low. Home-based dialysis care is also cost-effective and indeed the favoured dialysis option for many patients.

Methods & Objectives: Using a lean-thinking framework and established change management methodology, a project embracing a system-wide approach at making a change where a 'Home before Hospital' philosophy underpinned all approaches to dialysis care was undertaken.

Background Interprofessional education is directly linked to high-quality patient care, however, it remains unclear whether senior undergraduate medicine, nursing, and pharmacy students are ready for interprofessional education using high fidelity human patient simulators. Purpose The purpose of this study was to explore student's readiness for interprofessional learning and determine whether participation in high fidelity interprofessional education resulted in higher levels of readiness for interprofessional learning. Methods An interventional program starting with a pre-test before the program and a post-test after the program ends were designed with 24 students.

Sarcoidosis is a devastating inflammatory disease affecting many organs, especially the lungs and lymph nodes. Bone marrow-derived mesenchymal stromal cells (MSCs) can "reprogram" various types of macrophages towards an anti-inflammatory phenotype. We wanted to determine whether alveolar macrophages from sarcoidosis subjects behave similarly by mounting an anti-inflammatory response when co-cultured with MSCs.

Nursing, medicine, and pharmacy students have limited opportunities during their undergraduate programs to learn and practice together as an interprofessional team. This has prompted faculty at Memorial University of Newfoundland to explore the use of high fidelity simulated interprofessional education (HF-IPE) to help nursing, medicine, and pharmacy students learn about their roles, develop communication and collaboration skills, and foster teamwork. Research has shown that high fidelity simulated education can promote critical thinking, engage learners, improve confidence, and enhance psychomotor skills; however, there is limited data on the impact of HF-IPE on fostering teamwork.

More than 40,000 Canadians are living with end stage renal disease and approximately 22,400 of those are currently being treated with hemodialysis (The Kidney Foundation of Canada, 2013). Long distance travel to access hemodialysis services can be a serious burden for patients, and travelling more than 60 minutes can mean a 20% greater risk for death, as compared with those who travel 15 minutes or less (Moist et al., 2008).

Survivors of ventricular fibrillation cardiac arrest have poor and often devastating neurological outcomes despite advances in resuscitation techniques and services (Bernard et al., 2002; Collins & Samworth, 2008). In an effort to increase survival rates, improve neurological outcomes and reduce mortality for surviving patients, clinical trials have shown that a mild state of therapeutic hypothermia (32 degrees C to 34 degrees C) has been linked to improved patient outcomes post cardiac arrest (Koran, 2008; Lee & Asare, 2010).

The objective of this qualitative research study was to describe and interpret what life is like for individuals who have consented to donate the organs of a deceased relative for transplantation. This study captures the meaning of this phenomenon in a way to help nurses develop new insights into the lives of these individuals, enable them to implement strategies to better assist and support the family, and perhaps decrease barriers to organ donation. Thematic analysis of the participants' narrative descriptions identified five essential themes: the struggle to acknowledge the death, the need for a positive outcome of the death, creating a living memory, buying time, and the significance of support networks in the organ donation decision.
