Diagnosis and treatment of endogenous fungal endophthalmitis

Endogenous infectious endophthalmitis is rare, and a primary source is usually identified. A case of primary fungal endophthalmitis successfully treated with vitrectomy and systemic antifungal therapy is presented. The aetiology and treatment of the condition are discussed.

Illness perception clusters at diagnosis predict psychological distress among women with breast cancer at 6 months post-diagnosis.

OBJECTIVE:

This study aimed to examine the extent to which illness perceptions and coping strategies among women diagnosed with breast cancer explain psychological distress at diagnosis and at 6?months post diagnosis relative to demographic and illness-related variables.

METHODS:

Women were recruited to the study shortly after diagnosis. A total of 90 women completed study materials (Illness Perception Questionnaire-Revised, the Cancer Coping Questionnaire and the Hospital Anxiety and Depression Scale) at time 1. The same questionnaires were sent approximately 6?months later to those who had consented at time 1, and completed questionnaires were returned by 72 women.

RESULTS:

Cluster analysis was used to identify groups of respondents who reported a similar profile of illness perception scores. Regression analysis demonstrated that one of these clusters was more likely to experience psychological distress than the other both at diagnosis and at 6?months post diagnosis. Illness perception cluster membership and positive focus type coping were the most important and consistent predictors of lower psychological distress at diagnosis and at 6?months post diagnosis.

CONCLUSIONS:

Illness perceptions remained relatively stable over the study period, and therefore we are unable to clarify whether changes in illness cognitions are associated with a corresponding change in psychological symptoms. Future research should evaluate the impact on psychological distress of interventions specifically designed to modify illness cognitions among women with breast cancer.

Investigation of the Human Brain Metabolome to Identify Potential Markers for Early Diagnosis and Therapeutic Targets of Alzheimer’s Disease

A study combining high resolution mass spectrometry (liquid chromatography-quadrupole time-of-flight-mass spectrometry, UPLC-QTof-MS) and chemometrics for the analysis of post-mortem brain tissue from subjects with Alzheimer’s disease (AD) (n = 15) and healthy age-matched controls (n = 15) was undertaken. The huge potential of this metabolomics approach for distinguishing AD cases is underlined by the correct prediction of disease status in 94–97% of cases. Predictive power was confirmed in a blind test set of 60 samples, reaching 100% diagnostic accuracy. The approach also indicated compounds significantly altered in concentration following the onset of human AD. Using orthogonal partial least-squares discriminant analysis (OPLS-DA), a multivariate model was created for both modes of acquisition explaining the maximum amount of variation between sample groups (Positive Mode-R2 = 97%; Q2 = 93%; root mean squared error of validation (RMSEV) = 13%; Negative Mode-R2 = 99%; Q2 = 92%; RMSEV = 15%). In brain extracts, 1264 and 1457 ions of interest were detected for the different modes of acquisition (positive and negative, respectively). Incorporation of gender into the model increased predictive accuracy and decreased RMSEV values. High resolution UPLC-QTof-MS has not previously been employed to biochemically profile post-mortem brain tissue, and the novel methods described and validated herein prove its potential for making new discoveries related to the etiology, pathophysiology, and treatment of degenerative brain disorders.

Potentially inappropriate prescribing in older residents in Irish nursing homes

STOPP/START was formulated to identify potentially inappropriate prescribing (PIP) and potential prescribing omissions (PPOs) in older people. The purpose of this study was to determine the prevalence of PIP and PPO in older Irish patients in residential care using STOPP/START.

Availability of stage at diagnosis, cancer treatment delay and compliance with cancer guidelines as cancer registry indicators for cancer care in Europe:Results of EUROCHIP-3 survey

EUROCHIP (European Cancer Health Indicators Project) focuses on understanding inequalities in the cancer burden, care and survival by the indicators "stage at diagnosis," "cancer treatment delay" and "compliance with cancer guidelines" as the most important indicators. Our study aims at providing insight in whether cancer registries collect well-defined variables to determine these indicators in a comparative way. Eighty-six general European population-based cancer registries (PBCR) from 32 countries responded to the questionnaire, which was developed by EUROCHIP in collaboration with ENCR (European Network of Cancer Registries) and EUROCOURSE. Only 15% of all the PBCR in EU had all three indicators available. The indicator "stage at diagnosis" was gathered for at least one cancer site by 81% (using TNM in 39%). Variables for the indicator "cancer treatment delay" were collected by 37%. Availability of type of treatment (30%), surgery date (36%), starting date of radiotherapy (26%) and starting date of chemotherapy (23%) resulted in 15% of the PBCRs to be able to gather the indicator "compliance to guidelines". Lack of data source access and qualified staff were the major reasons for not collecting all the variables. In conclusion, based on self-reporting, a few of the participating PBCRs had data available which could be used for clinical audits, evaluation of cancer care projects, survival and for monitoring national cancer control strategies. Extra efforts should be made to improve this very efficient tool to compare cancer burden and the effects of the national cancer plans over Europe and to learn from each other. © 2012 UICC.

Stress, coping and burn-out in nursing students

Aim: To explore the relationship between sources of stress and psychological burn-out and to consider the moderating and mediating role played sources of stress and different coping resources on burn-out.

Background: Most research exploring sources of stress and coping in nursing students construes stress as psychological distress. Little research has considered those sources of stress likely to enhance well-being and, by implication, learning.

Method: A questionnaire was administered to 171 final year nursing students. Questions were asked which measured sources of stress when rated as likely to contribute to distress (a hassle) and rated as likely to help one achieve (an uplift). Support, control, self-efficacy and coping style were also measured, along with their potential moderating and mediating effect on burn-out.

Findings: The sources of stress likely to lead to distress were more often predictors of wellbeing than sources of stress likely to lead to positive, eustress states. However, placement experience was an important source of stress likely to lead to eustress. Self-efficacy, dispositional control and support were other important predictors. Avoidance coping was the strongest predictor of burn-out and, even if used only occasionally, it can have an adverse effect on burn-out. Initiatives to promote support and self-efficacy are likely to have the more immediate benefits in enhancing student well-being.

Conclusion: Nurse educators need to consider how course experiences contribute not just to potential distress but to eustress. How educators interact with their students and how they give feedback offers important opportunities to promote self-efficacy and provide valuable support. Peer support is a critical coping resource and can be bolstered through induction and through learning and teaching initiatives. 

Stress and eustress in nursing students

Aim. This paper is a report of a study to identify experiences that led to both distress and eustress and to make recommendations to help students cope with course demands.

Background. Much of the research on stress in nursing students is quantitative in focus and all draws on their experience of distress, with little attempt to understand experiences of eustress.

Method. A series of focus groups were carried out with a volunteer sample of final year nursing students (n = 16) in the United Kingdom in 2007. The data were thematically analysed.

Findings. The themes identified were clinical experience, support, learning and teaching experience and course structure. There were experiences within each that were perceived as sources of distress and eustress. Many of the sources of distress concur with earlier findings but they are more likely to be experienced and commented on because the demands of present-day programmes and the profile of many nursing students mean that more effort is invested in meeting educational demands. The experiential learning and patient-care opportunity that placements provided was an important source of eustress.

Conclusion. Students who coped well drew on effective support networks and adopted a positive, optimistic perspective towards programme issues. Effective educators did not offer more time than those perceived as less effective but seemed more effective at tuning into students' concerns, showing more empathy and offering clearer guidance.

Relationships between adrenocorticotropic hormone and cortisol are altered during clustered nursing care in preterm infants born at extremely low gestational age

Little is known about the effects of clustered nursing care on hypothalamic pituitary axis (HPA) responses in preterm infants in the neonatal intensive care unit.

The experiences of palliative care health service provision for people with non-malignant respiratory disease and their caregivers: an all-Ireland study

Aim: To explore the perception of palliative care provision for people with non-malignant respiratory disease from the perspective of bereaved caregivers.

Background: It is recognized that the majority of patients diagnosed with a malignant disease will have access to palliative care provision. However, it is less clear if the same standards of palliative care are available to those with non-malignant respiratory disease in Northern Ireland and the Republic of Ireland.

Design: A qualitative study based on broad interpretivism.

Methods: This research is a PhD study funded by the Department of Education and Learning in Northern Ireland (awarded February 2011). Data collection will consist of two stages; interviews with 20 bereaved caregivers of people who have died 3–18 months previously with a diagnosis of non-malignant respiratory disease and four focus groups with healthcare professionals involved in the care of this client group. This study will be carried out at four healthcare sites across the Island of Ireland. The data will be analysed using thematic content analysis. Research Ethics committee approval was obtained (March 2012).

Discussion: This research will explore the experiences of patients with Chronic Obstructive Pulmonary Disease, Interstitial Lung Disease and Bronchiectasis and their caregivers from the perspective of the bereaved caregiver. The outcomes of this study will provide a critical first step in the development of more responsive palliative care for this client group and have important implications for future practice and policy in the palliative care provided to this client group.

Service preferences among family caregivers of the terminally ill

Objective: The ability of families to assume caregiving responsibilities is contingent on material, social, and professional support. Inadequate or inappropriate support to the terminally ill and their family caregivers can result in the misuse of resources and add burden to the family. In this report, we describe service preferences among informal caregivers of the terminally ill. Design: Three hundred seventy-three caregivers participated in telephone interviews at two points in time: when the terminally ill person was designated as palliative and 5 months subsequent to the first interview. In the case that the care recipient died during the study period, the caregiver participated in the interview three months after the death. Measures: After reviewing possible services received by the care recipients and caregivers, caregivers were asked to identify the five services they found most valuable and which services they would have liked to have had or received more of when caregiving. Results: The five services caregivers reported as most valuable included: in-home nursing care, (90.7%); family physicians, (45.6%); medical specialists, (46.4%); housekeeping, (23.6%); and, religious support, (11.3%). The five most frequently reported services that family caregivers would have liked to have received or had more available included: housekeeping, (13.1%); caregiver respite, (10.2%); in-home nursing care, (8.0%); personal support workers, (4.6%); and, self-help/support groups, (3.8%). Analyses revealed that most (64.8%) perceived service needs were of a supportive nature for caregivers. Caregiver perceptions of the value and perceived need of services were consistent over time and into bereavement. Logistic regression analyses suggested that younger caregivers who were not employed, reported higher levels of burden and cared for someone with a diagnosis of cancer had greater perceived service needs. Conclusions: The findings reported in this paper provide important insights into caregiver perceptions of valued services when caring for a terminally ill family member. These finding also highlight the stability of caregiver service perceptions over time and into bereavement.

The impact of specialized oncology nursing on patient supportive care outcomes

Meeting the supportive care needs of cancer patients remains a challenge to cancer care systems around the world. Despite significant improvements in the organization of medical care of patients with cancer, numerous surveys of cancer populations demonstrate that significant proportions of patients fail to have their supportive care needs met. One possible solution is the introduction of a care coordinator role using oncology nursing to help ensure that patients' physical, psychological, and social support needs are addressed. Although having face validity, there is little empirical evidence on the effects of nurse-led supportive care coordinator roles on patient reported supportive care outcomes. In this article the authors present the results of a prospective longitudinal cohort study of 113 patients referred to a community-based specialist oncology nursing program. Using validated instruments they found significant improvements in patient-reported outcomes in key supportive care domains: unmet needs, quality of life, and continuity of care, as well as a shift in patterns of health resource utilization from acute care settings to the community over the course of the intervention. The results of this study are important in supporting the design and development of controlled trials to examine provider roles in the coordination of supportive cancer care.

Resource utilization and cost analyses of home-based palliative care service provision:The Niagara West End-of-Life Shared-Care Project

Background: Increasing emphasis is being placed on the economics of health care service delivery - including home-based palliative care. Aim: This paper analyzes resource utilization and costs of a shared-care demonstration project in rural Ontario (Canada) from the public health care system's perspective. Design: To provide enhanced end-of-life care, the shared-care approach ensured exchange of expertise and knowledge and coordination of services in line with the understood goals of care. Resource utilization and costs were tracked over the 15 month study period from January 2005 to March 2006. Results: Of the 95 study participants (average age 71 years), 83 had a cancer diagnosis (87%); the non-cancer diagnoses (12 patients, 13%) included mainly advanced heart diseases and COPD. Community Care Access Centre and Enhanced Palliative Care Team-based homemaking and specialized nursing services were the most frequented offerings, followed by equipment/transportation services and palliative care consults for pain and symptom management. Total costs for all patient-related services (in 2007 CAN) were 1,625,658.07 - or 17,112.19 per patient/117.95 per patient day. Conclusion: While higher than expenditures previously reported for a cancer-only population in an urban Ontario setting, the costs were still within the parameters of the US Medicare Hospice Benefits, on a par with the per diem funding assigned for long-term care homes and lower than both average alternate level of care and hospital costs within the Province of Ontario. The study results may assist service planners in the appropriate allocation of resources and service packaging to meet the complex needs of palliative care populations. © 2012 The Author(s).

Pneumonia and lower respiratory infections in nursing home residents:Predictors of hospitalization and mortality

OBJECTIVES: To compare predictors of hospitalization and death in nursing home residents with pneumonia and other lower respiratory infections (LRIs). DESIGN: A nested cohort study. SETTING: Nine nursing homes in southern Ontario. PARTICIPANTS: Three hundred fifty-three nursing home residents with LRIs (enrolled in the control arm of a clinical trial). MEASUREMENTS: Comorbidities, vaccination status, age, health-related quality of life, functional status, and vital statistics were evaluated as potential predictors of hospitalization and mortality at 30 days. RESULTS: Moderate to high disease severity score on a practical severity scale was a strong independent predictor of hospitalization (odds ratio (OR)=7.12, P
