Caring in nursing homes to promote autonomy and participation.

BACKGROUND:: Autonomy and participation are threatened within the group of older people living in nursing homes. Evidence suggests that healthcare personnel act on behalf of older people but are still excluding them from decision-making in everyday care. OBJECTIVE:: The purpose was to describe registered nurses' experience of caring for older people in nursing homes to promote autonomy and participation. RESEARCH DESIGN:: A descriptive design with a phenomenological approach was used. Data were collected by semi-structured individual interviews. Analysis was inspired by Giorgi's method. PARTICIPANTS AND RESEARCH CONTEXT:: A total of 13 registered nurses from 10 nursing homes participated. ETHICAL CONSIDERATIONS:: Ethical approval was obtained from the Regional Research Ethics Committee. Informed consent was achieved and confidentiality guaranteed. FINDINGS:: The essence of caring for older people in nursing homes to promote autonomy and participation consisted of registered nurses' awareness of older people's frailty and the impact of illness to support health and well-being, and awareness of acknowledgement in everyday life and trusting relationships. Paying attention to older people by being open to the persons' wishes were aspects that relied on registered nurses' trusting relationships with older people, their relatives and surrounding healthcare personnel. The awareness reflected challenges in caring to promote older people's right to autonomy and participation in nursing homes. Registered nurses' strategies, hopes for and/or concerns about development of everyday life in nursing homes were revealed and mirrored their engagement in caring for older people. DISCUSSION AND CONCLUSION:: Awareness of older people's frailty in nursing homes and the importance of maintained health and well-being were described as the main source for promoting autonomy and participation. Everyday life and care in nursing homes needs to be addressed from both older people's and healthcare personnel's perspectives, to promote autonomy and participation for residents in nursing homes.

Life memories and the ability to act: the meaning of autonomy and participation for older people when living with chronic illness.

There is a lack of knowledge about how older people living with chronic illness describe the meaning of autonomy and participation, indicating a risk for reduced autonomy and participation in their everyday life. The purpose of this study was to describe the meaning of autonomy and participation among older people living with chronic illness in accordance with their lived experience. The design was descriptive with a phenomenological approach guided by Giorgi's descriptive phenomenological psychological method. Purposive sampling was used, and 16 older people living with chronic illness who lived in an ordinary home participated in individual interviews. The findings showed that the meaning of autonomy and participation among the older people emerged when it was challenged and evoked emotional considerations of the lived experience of having a chronic illness. It involved living a life apart, yet still being someone who is able, trustworthy and given responsibility--still being seen and acknowledged. The meaning of autonomy and participation was derived through life memories and used by the older people in everyday life for adjustment or adaption to the present life and the future. Our conclusion is that autonomy and participation were considered in relation to older people's life memories in the past, in their present situation and also their future wishes. Ability or disability is of less importance than the meaning of everyday life among older people. We suggest using fewer labels for limitations in everyday life when caring for older people and more use of the phrase 'ability to act' in different ways, based on older people's descriptions of the meaning of autonomy and participation.

Cryopreserved peripheral blood mononuclear cells are suitable for the assessment of immunological markers in type 1 diabetic children.

Cryopreserved peripheral blood mononuclear cells (PBMC) are commonly used when assessing immune responses in clinical trials, both for practical reasons and to minimize interassay variation, as samples are often collected and studied over time. This study investigated the effect of cryopreservation on cytokine and chemokine secretion, and on expression of regulatory T-cell associated markers, in samples from children with type 1 diabetes. PBMC were cultured before and after cryopreservation either with GAD(65) or PHA. Secretion of cytokines (IL-5, -6, -10, -12, -13 -17, IFN-gamma and TNF-alpha) and chemokines (IP-10, MCP-1, MIP-1alpha, MIP-1beta and RANTES) was analysed in cell supernatants using multiplex fluorochrome technique (Luminex). Expression of FOXP3 and TGF-beta mRNA was detected by multiplex real-time RT-PCR. Increased spontaneous secretion of IL-6, -10, -12, -13, IFN-gamma and MCP-1, and mRNA expression of FOXP3 and TGF-beta, was detected after cryopreservation. Stimulation with GAD(65) induced higher levels of IL-6, IFN-gamma, TNF-alpha and MIP-1alpha, whereas lower secretion was found for IL-10 and IL-13 in cryopreserved PBMC. Stimulation with PHA induced lower secretion of IP-10, MCP-1 and RANTES and FOXP3 mRNA expression after cryopreservation. Thus, cryopreserved PBMC were suitable to assess the immunological markers included in this study, even though their expression could differ from freshly handled cells.

Nicotinamide reduces high secretion of IFN-gamma in high-risk relatives even though it does not prevent type 1 diabetes.

Type 1 diabetes (T1D) is an autoimmune disease suggested to be of a T helper (Th)1-like origin. This study aimed to investigate the Th1-like and Th2-like profile in high-risk individuals during the prediabetic phase and the immunologic effect of treatment with nicotinamide. High-risk first-degree relatives of T1D patients participating in the European Nicotinamide Diabetes Intervention Trial (ENDIT) were treated with either nicotinamide or placebo. Peripheral blood mononuclear cells (PBMC) were obtained during the prediabetic phase and close to the onset of manifest T1D and from nondiabetic high-risk individuals. Using the sensitive enzyme-linked immunospot (ELISPOT) technique to distinguish Th1-like from Th2-like lymphocytes, secretion of interferon-gamma (IFN-gamma) and interleukin-4 (IL-4) was analyzed from PBMCs spontaneously and after in vitro stimulation with the diabetes-associated autoantigens, glutamic acid decarboxylase 65 (GAD65, protein and peptide, aa 247-279), recombinant tyrosine phosphatase (IA-2), and heat shock protein (HSP, aa 437-460). High-risk individuals showed high spontaneous as well as autoantigen-induced IFN-gamma secretion. Secretion of IFN-gamma and the IFN-gamma/IL-4 ratio, induced by autoantigens, decreased in individuals developing T1D (p < 0.05), whereas nondiabetic individuals showed an increased IL-4 response (p < 0.05). Thus, a Th1-dominated cytokine profile observed in high-risk individuals inclined toward a diagnosis of diabetes. Nicotinamide caused decreased spontaneous (p = 0.05) and in vitro autoantigen-induced IFN-gamma secretion (p < 0.05) and may play a role in immune regulation, even though it has not been shown to prevent T1D.

DNA hypomethylation and methyltransferase expression in atherosclerotic lesions.

Arterial smooth muscle cell (SMC) migration and proliferation are central features in atherogenesis. Altered gene expression and cell proliferation in atherosclerotic lesions have some similar characteristics with certain solid tumors and thus might have similar mechanisms that lead to SMC proliferation. Among cancer cells common features are genome-wide hypomethylation which correlates with transformation and tumor progression, and coincident overexpression of methyltransferase (MTase). The purpose of the present study was to analyze whether alterations in DNA methylation and MTase expression are present in atherosclerotic lesions. A significant reduction in genomic 5-methylcytosine content was detected in advanced human atherosclerotic lesions and in lesions of ApoE knock-out mice. SMC were shown to develop hypomethylation in vitro during transformation from a contractile to synthetic phenotype. Balloon denudation of New Zealand White rabbit aorta caused proliferation of intimal SMC with concomitant genomic hypomethylation in the thickened intima. By using in situ hybridization the overall transcriptional activity was found to be increased in clusters of lesion SMC. Marked heterogeneity was seen in MTase mRNA expression in various types of atherosclerotic lesions among intimal and medial SMC. These findings show that (1) genomic hypomethylation occurs during atherogenesis in human, mouse and rabbit lesions and that it correlates with increased transcriptional activity; (2) MTase is expressed in atherosclerotic lesions; and (3) hypomethylation is present in advanced lesions at the same level as in malignant tumors and may affect cellular proliferation and gene expression in atherosclerotic lesions.

Improved detection of homologous membrane proteins by inclusion of information from topology predictions.

A total of 20%-25% of the proteins in a typical genome are helical membrane proteins. The transmembrane regions of these proteins have markedly different properties when compared with globular proteins. This presents a problem when homology search algorithms optimized for globular proteins are applied to membrane proteins. Here we present modifications of the standard Smith-Waterman and profile search algorithms that significantly improve the detection of related membrane proteins. The improvement is based on the inclusion of information about predicted transmembrane segments in the alignment algorithm. This is done by simply increasing the alignment score if two residues predicted to belong to transmembrane segments are aligned with each other. Benchmarking over a test set of G-protein-coupled receptor sequences shows that the number of false positives is significantly reduced in this way, both when closely related and distantly related proteins are searched for.
