ABSTRACT
BACKGROUND: Incidence of disability secondary to Parkinson's disease is increasing faster globally than any other neurological condition. The diverse appearance of symptomatology associated with Parkinson's, and the degenerative nature and subsequent functional decline, often increase dependence on caregivers for assistance with daily living, most commonly within a care home setting. Yet, primary literature and evidence synthesis surrounding these unique and complex care needs, challenges and the lived experiences of this population living in long-term nursing or residential facilities remains sparce. The aim of this review is to synthesize qualitative literature about the lived experience of people with Parkinson's disease living in care home settings. METHODS: A systematic search of the literature was conducted in October 2023 across six different databases (CINAHL, Medline, EMBASE, PsycINFO, Scopus and Cochrane Library). The Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) was used to guide this review. RESULTS: Five articles met the inclusion criteria. Four themes were identified following evidence synthesis: (1) Unique pharmacological challenges. (2) Transitioning and adapting to care home life and routines. (3) Dignified care within care homes. (4) Multidisciplinary care vacuum in care homes. CONCLUSION: This review revealed the significant and unique challenges for people with Parkinson's disease when transitioning into care homes. These are exacerbated by wider social care challenges such as staffing levels, skill mixes and attitudes as well as a lack of disease-specific knowledge surrounding symptomatology and pharmacology. The lack of multi-disciplinary working and risk-adverse practice inhibited person-centred care and autonomy and reduced the quality of life of people living with Parkinson's disease in care homes. Recommendations for practice highlight training gaps, the need for consistent and improved interdisciplinary working and better person-centred assessment and care delivery.
ABSTRACT
BACKGROUND: Parkinson's Disease (PD) is a common neurological condition that often causes stiffness, tremor and slow movement. People living with PD are likely to encounter nursing students throughout their journey from pre-diagnosis to death. Despite this, there is a paucity of evidence about current practice in PD education amongst nursing students. The present study provides an evaluation of a co-designed Parkinson's Awareness audio podcast amongst nursing students in Northern Ireland. METHODS: Following co-design of an audio podcast about PD, a mixed methods evaluation was carried out. 332 student nurses completed pre-/post-test questionnaires about their knowledge and perceptions of PD before and after listening to the audio podcast. Further to this, 35 student nurses participated in focus-group interviews six months following listening to explore how the podcast influenced practice. RESULTS: Student nurses posted a mean score of 52% before listening to the audio podcast. This mean increased to 80% post-test. These findings were statistically significant (p < 0.001), demonstrating significant increases in PD awareness after listening. Findings from the focus groups suggested that the audio podcast improved empathy and practice towards people with PD. The findings also suggested that students perceived audio podcasts to be a good way to learn about PD. CONCLUSION: Provision of a co-designed audio podcast about PD has the potential to improve student nurse knowledge and practice related to PD as evidenced in this study.
ABSTRACT
The role of leadership in nursing and healthcare is continuously being examined, and has undergone increasing public and media scrutiny due to the coronavirus disease 2019 (COVID-19) pandemic. This article details a project that brought together five final-year nursing students and two experienced nurses who had all worked as part of the early response to the pandemic. Meeting regularly online, the participants sought to explore the literature on nursing leadership as well as their own clinical experience and personal reflections of leadership during the pandemic. This process, which took place over a period of four months, also enabled the participants to examine their own leadership style. Four themes emerged from the group discussions: learning about and building on the history of nursing, the participants' role in nursing leadership, effective leadership during times of uncertainty and the role of communication in effective leadership.

The use of proteomics for efficient, accurate, and complete analysis of clinical samples poses a variety of technical challenges. The presence of higher abundance proteins in the plasma, such as albumin, may mask the detection of lower abundance proteins such as the cytokines. Methods have been proposed to deplete the sample of these higher abundance proteins to facilitate detection of those with lower abundance. In this study, a commercially available albumin depletion kit was used to determine if removal of albumin would measurably reduce detection of lower abundance cytokine proteins in human plasma. The Montage Albumin Deplete Kit (Millipore) was used to deplete albumin from LPS-stimulated whole blood from 15 normal human donors. Albumin depletion was measured using the BCG reagent and SDS-PAGE, and cytokine recovery was determined by a microassay immunoassay that measures both pro- and anti-inflammatory cytokines. Average albumin depletion from the samples was 72%. However, several cytokines were also significantly reduced when the albumin was removed from the plasma. Additionally, there was a variable reduction in cytokine recovery from a known mixture of cytokines in a minimal amount of plasma that were loaded onto the columns. These data demonstrate that there may be a non-specific loss of cytokines following albumin depletion, which may confound subsequent proteomic analysis.

Due to the low cost and relative effectiveness the enzyme-linked immunosorbent assay (ELISA) is widely used to measure the concentration of inflammatory cytokines in plasma and other sources. Blood volume represents a limiting factor in those mouse models requiring repeated sample collection at multiple time intervals to monitor the trajectory of inflammatory processes. The small blood volumes in such scenarios restrict the array of cytokines that can be measured using the traditional ELISA. The implementation of the sequential ELISA protocol presented here can dramatically increase the number of measured cytokines, since the plasma samples are not discarded after the initial assay but re-used to measure additional selected inflammatory proteins in consecutive tests. From the original 20 mul of blood volume collected, up to fifteen cytokines can be successfully assayed in five consecutive cycles. With more unstable cytokines analyzed in the initial cycles, no inter-assay interference and/or deterioration of samples occurs. The sequential ELISA technique based on commercially-available antibody pairs can be an attractive alternative to more advanced, costly methods. Given the simplistic validation procedure, the proposed sequential ELISA protocol has a wide potential for further modifications to include other inflammation-related targets.

Previous studies have suggested that interleukin-6 (IL-6) serves as both a marker and a mediator for the severity of sepsis. We tested whether interleukin 6 knockout (IL-6KO) mice were more susceptible to sepsis mortality induced by cecal ligation and puncture. IL-6KO and wild-type (WT) mice were subjected to increasing degrees of sepsis severity. Physiologic support was given with fluids and appropriate antibiotics. Plasma IL-6 levels were determined 6 h after the onset of sepsis, and a complete hematologic profile was performed on day 2. As expected, increasing sepsis severity resulted in greater and more rapid mortality. However, the mortality was nearly identical in the IL-6KO and WT mice. All WT septic mice had high plasma levels of IL-6 6 h after the onset of sepsis, while IL-6KO were near or below the lower limit of detection. Among the WT mice, mortality was significantly higher in mice with plasma IL-6 >3,000 pg/ml. Both IL-6KO and WT mice destined to die in the early stages of sepsis had substantial and nearly identical weight gain in the first 24 h. However, at later stages the WT mice had significantly greater weight loss than the KO mice. The KO mice failed to develop the characteristic hypothermia within the first 24 h of severe sepsis routinely observed in the WT mice. These data demonstrate that IL-6 serves as a marker of disease severity in sepsis and does modulate some physiologic responses, but complete lack of IL-6 does not does not alter mortality due to sepsis.

Endotoxin injection has been widely used to study the acute inflammatory response. In this study, we directly compared the inflammatory responses to endotoxin in mice and humans. Escherichia coli type O113 endotoxin was prepared under identical conditions, verified to be of equal biological potency, and used for both mice and humans. The dose of endotoxin needed to induce an interleukin-6 (IL-6) concentration in plasma of approximately 1,000 pg/ml 2 h after injection was 2 ng/kg of body weight in humans and 500 ng/kg in mice. Healthy adult volunteers were injected intravenously with endotoxin, and male C57BL/6 mice (n=4 to 12) were injected intraperitoneally with endotoxin. Physiological, hematological, and cytokine responses were determined. Endotoxin induced a rapid physiological response in humans (fever, tachycardia, and slight hypotension) but not in mice. Both mice and humans exhibited lymphopenia with a nadir at 4 h and recovery by 24 h. The levels of tumor necrosis factor (TNF) and IL-6 in plasma peaked at 2 h and returned to baseline levels by 4 to 6 h. IL-1 receptor antagonist RA and TNF soluble receptor I were upregulated in both mice and humans but were upregulated more strongly in humans. Mice produced greater levels of CXC chemokines, and both mice and humans exhibited peak production at 2 h. These studies demonstrate that although differences exist and a higher endotoxin challenge is necessary in mice, there are several similarities in the inflammatory response to endotoxin in mice and humans.

Cytokine and cytokine inhibitors represent important components of the inflammatory response in patients with trauma, shock, and sepsis. Many investigators wish to quantify cytokines and it would be advantageous to measure multiple cytokines in a multiplex manner to obtain an inflammatory profile rather than a single value. Using the well-accepted standard enzyme-linked immunoassay (ELISA) as a basis, a microarray immunoassay (MI) was designed to measure 16 different human cytokines simultaneously. The MI was performed by spotting antibodies on nitrocellulose pads affixed to glass slides. Detection of the mediators was performed with biotin-conjugated antibodies followed by fluorescently labeled streptavidin. All antibodies and other reagents were purchased commercially. The MI achieved a lower limit of detection that was generally similar to traditional ELISAs (approximately 4-12 pg/mL) and also had a similar coefficient of variation. In the multiplexed MI, there was no cross reactivity between mediators. To verify the utility of the MI, cytokines and cytokine inhibitors were measured in endotoxin stimulated human blood by both ELISA and MI. Virtually identical cytokine concentrations were measured by both methods. These results describe the development of a sensitive, specific and cost-effective multiplexed microarray immunoassay that produces values similar to traditional ELISAs.
