Mindfulness as a well-being initiative for future nurses: a survey with undergraduate nursing students

Background Mindfulness can potentially positively impact well-being and resilience in undergraduate nursing students. The psychological well-being of such students undertaking clinical training is paramount to ensure optimal learning, and to equip them with skills to manage their wellbeing in future clinical practice. The aim of our study was to explore the views of undergraduate nursing students in relation to understanding and engaging with mindfulness, and how mindfulness could best be delivered within their university programme. Methods An online survey was administered via a cloud-based student response system to a convenience sample of first year undergraduate nursing students completing a Bachelor of Science (BSc) Honours (Hons) degree in nursing at a University in the United Kingdom. Data were analysed using descriptive statistics and thematic analysis. Results The survey achieved a response rate of 78% (n = 208). Seventy-nine percent of participants had heard of mindfulness and were interested in taking part in a mindfulness programme. Respondents reported that the ideal delivery of the programme would consist of weekly 45-min, in person group sessions, over a 6-week period. Respondents also indicated that a mobile application could potentially facilitate participation in the programme. Thematic analysis of open-ended comments, and free text, within the survey indicated 4 overarching themes: 1) Perceptions of what mindfulness is; 2) Previous mindfulness practice experiences; 3) Impact of mindfulness in nursing; 4) The need for a future well-being initiative for undergraduate nursing students. Conclusions Undergraduate nursing students perceived that a mindfulness programme has the potential to enhance well-being and future clinical practice. This student cohort are familiar with mindfulness and want more integrated within their undergraduate curriculum. Further research is required to examine the effectiveness of a tailored mindfulness intervention for this population that incorporates the use of both face-to-face and mobile delivery

Palliative care for people with non-malignant respiratory disease and their carers: a review of the current evidence

© The Author(s) 2019. Background: Internationally, non-malignant respiratory disease is on the increase. However, although palliative care is recommended as an appropriate healthcare option for this client group, evidence suggests that these patients and their carers do not receive the same standards of palliative care as patients with a malignant lung condition. Aim: The aim of this review was to provide a critical overview of the current evidence base in relation to the palliative service provision for people with non-malignant respiratory disease and their carers. Methods: A review of the literature was conducted in July 2015 and updated in October 2017 and focused on the palliative care service provision for patients with interstitial lung disease, chronic obstructive pulmonary disease and bronchiectasis. Results: In total, 71 empirical studies were included in the review and grouped into two main themes: patient and carer’s bio-psychosocial symptom needs and management, and palliative care service provision for patients with non-malignant respiratory disease and their carers. Conclusion: The majority of palliative research focuses on patients with a diagnosis of chronic obstructive pulmonary disease. A deeper insight is required into the palliative service provision experienced by those with other forms of non-malignant respiratory disease such as bronchiectasis and interstitial lung disease

The experience of palliative care service provision for people with non-malignant respiratory disease and their family carers: an all-Ireland qualitative study.

AIM: To explore specialist and generalist palliative care provision for people with non-malignant respiratory disease, in rural and urban areas in the North and Republic of Ireland. BACKGROUND: Globally, palliative care is recommended as an appropriate healthcare option for people with advanced non- malignant lung disease. Yet, there is limited evidence regarding the integration of palliative care for this client group. DESIGN: Qualitative study. METHODS: Convenience sample of 17 bereaved carers and 18 healthcare professionals recruited from two rural and two urban sites on the Island of Ireland. Data were collected throughout 2012 and 2013 through semi-structured interviews with carers of patients with Chronic Obstructive Pulmonary Disease (N=12), interstitial lung disease (N=4) or bronchiectasis (N=1) who had died 3-18 months previously; and 4 focus groups with healthcare professionals. Data were analysed using a thematic analysis framework. RESULTS: Carers' interviews yielded three overarching themes:1) Lack of preparedness for death, due to ambiguity regarding disease trajectory; 2) Lack of consistency in palliative care delivery, in relation to the receipt of generalist and specialist palliative care; and 3) Role ambiguity, related to their caregiving role. Focus groups identified two overarching themes:1) Barriers to appropriate palliative care; and 2) The future direction of palliative care for patient with non-malignant respiratory disease. CONCLUSION: The uncertain disease trajectory was not only experienced by carers but also healthcare professionals. Although referral to specialist palliative care services was perceived as increasing, the availability and coordination of generalist and specialist palliative care services were fragmented and varied dependent on geographical location.

Neutral sphingomyelinase mediates the co-morbidity trias of alcohol abuse, major depression and bone defects

Mental disorders are highly comorbid and occur together with physical diseases, which are often considered to arise from separate pathogenic pathways. We observed in alcohol-dependent patients increased serum activity of neutral sphingomyelinase. A genetic association analysis in 456,693 volunteers found associations of haplotypes of SMPD3 coding for NSM-2 (NSM) with alcohol consumption, but also with affective state, and bone mineralisation. Functional analysis in mice showed that NSM controls alcohol consumption, affective behaviour, and their interaction by regulating hippocampal volume, cortical connectivity, and monoaminergic responses. Furthermore, NSM controlled bone–brain communication by enhancing osteocalcin signalling, which can independently supress alcohol consumption and reduce depressive behaviour. Altogether, we identified a single gene source for multiple pathways originating in the brain and bone, which interlink disorders of a mental–physical co-morbidity trias of alcohol abuse—depression/anxiety—bone disorder. Targeting NSM and osteocalcin signalling may, thus, provide a new systems approach in the treatment of a mental–physical co-morbidity trias
