RESUMO
Globally, the nursing profession constitutes the largest proportion of the health workforce; however, it is challenged by widespread workforce shortages relative to need. Strategies to promote recruitment of the nursing workforce are well-established, with a lesser focus on strategies to alleviate the burden on the existing workforce. This burden may be exacerbated by the impact of low-value health care, characterised as health care that provides little or no benefit for patients, or has the potential to cause harm. Low-value health care is a global problem, a major contributor to the waste of healthcare resources, and a key focus of health system reform. Evidence of variation in low-value health care has been identified across countries and system levels. Research on low-value health care has largely focused on the medical profession, with a paucity of research examining either low-value health care or the de-implementation of low-value health care from a nursing perspective. The objective of this paper is to provide a scholarly discussion of the literature around low-value health care and de-implementation, with the purpose of identifying implications for nursing research. With increasing pressures on the global nursing workforce, research identifying low-value health care and developing approaches to de-implement this care, is crucial.

PURPOSE: Purpose: Between 55-65% of residents living in residential aged care facilities (RACFs) experience dysphagia and are prescribed texture-modified diets by a speech-language pathologist (SLP). The aim of this study was to assess current adherence to prescribed texture modification for people with dysphagia; and explore barriers to implementation in a rural aged care setting. METHOD: Method: Meal texture audits (N = 42) were completed with residents with dysphagia in a rural RACF who were prescribed texture-modified diets or fluids by a SLP. Semi-structured focus groups were conducted with nursing and food preparation staff (N = 11) to identify barriers to implementation. RESULT: Result: Mealtime texture audits identified that 54.8% (n = 23) of residents' food modification requirements were incorrectly documented in the manual entry database (kitchen form) and 64.3% (n = 27) of meal trays contained foods that did not meet residents' dysphagia management plans. Focus group data revealed seven main themes impacting on the ability of staff to implement prescribed texture-modified diets. Complicated processes and communication between nursing, food services and SLP staff were identified as major barriers. These were complicated further by time pressures experienced by staff as well as staffing issues, resourcing of the kitchen, accommodating individual dietary preferences and the variety/presentation of dietary options at the aged care facility.Conclusion: There was low adherence to SLP prescribed texture-modified diets and fluids in the participating rural RACF. This study identified major barriers to implementing SLP prescribed texture-modified diets including complicated processes, communication breakdowns, time pressures and limited staffing. Implementation of an online menu management system and regular dysphagia-specific training may address barriers to communication and complicated paper-based menu systems and should be a priority for health services to ensure adequate dysphagia management.

Gliomas are diffuse and hard to cure brain tumors. A major reason for their aggressive behavior is their property to infiltrate the brain. The gross appearance of the infiltrative component is comparable to normal brain, constituting an obstacle to extended surgical resection. 5-ALA induced PpIX fluorescence measurements enable gains in sensitivity to detect infiltrated cells, but still lack sensitivity to get accurate discrimination between the tumor margin and healthy tissue. In this fluorescence spectroscopic study, we assume that two states of PpIX contribute to total fluorescence to get better discrimination of healthy tissues against tumor margins. We reveal that fluorescence in low-density margins of high-grade gliomas or in low-grade gliomas is mainly influenced by the second state of PpIX centered at 620 nm. We thus conclude that consideration of the contributions of both states to total fluorescence can help to improve fluorescence-guided resection of gliomas by discriminating healthy tissues from tumor margins.

AIM: To investigate recall for technical reasons within the UK Breast Screening Programme, and to determine whether differences exist in those women using hormone replacement therapy (HRT), considering potential associations with reported pain, compression force used and compressed breast thickness (CBT) obtained. MATERIALS AND METHOD: A prospective cohort study of 2765 women attending for incident round breast screening appointments who were either HRT users, with a minimum of 1 year duration (n=1077), or had never used HRT (n=1688). Data were collected using technical recall records, a radiographer data-collection sheet, and a self-administered participant questionnaire. RESULTS: Sixty-eight (2.5%) participants were recalled for technical reasons of whom 28 (2.6%) were HRT and 40 (2.4%) non-HRT users. This difference was not statistically significant (p=0.80). Significant differences were found for CBT between those HRT users who were and were not recalled for technical reasons (p<0.01) and for the similar categories of non-HRT users (p=0.03). No significant differences were found for force between those HRT users who were recalled or not (p=0.73) and for the similar categories of non-HRT users (p=0.07). Similarly no significant differences were found for pain between those HRT users who were recalled or not (p=0.75) and for the similar categories of non-HRT users (p=0.73). CONCLUSION: CBT was the only variable to have both a statistically and a clinically significant relationship with technical recall.

PURPOSE: Human solid tumors undergo multiple genetic evolutionary changes as they evolve from the normal state to advanced stages of malignancy. This study characterizes the degree of advancement of primary human breast cancers in their genetic evolutionary pathways, and determines if this is of clinical significance. MATERIALS AND METHODS: Correlated cell-by-cell measurements of cell DNA content, HER-2/neu protein content per cell, and H-ras protein content per cell were obtained by means of multiparameter flow cytometry on primary tumors from 95 patients with clinically localized breast cancer. Laboratory findings were correlated with subsequent clinical course in 91 of these patients. RESULTS: Multiple genetic abnormalities were found to accumulate in individual cells in primary human breast cancers. Almost all tumors contained subsets of cells with one, two, or three abnormalities per cell in various combinations. After a median follow-up time of 32 months, 11 of 13 patients with early recurrence had primary tumors in which more than 5% of cells were hypertetraploid, overexpressed HER-2/neu protein, and overexpressed H-ras protein (triple-positive cells). The duration of disease-free survival among patients with primary tumors that contained triple-positive cells was significantly shorter than for patients whose tumors did not contain triple-positive cells. The presence of subpopulations of cells with maximums of only one abnormality per cell or only two abnormalities per cell, in any combination, was of no prognostic significance. Among patients whose nodal status was known, 12 had recurrent disease, and all had positive axillary nodes. Among 36 patients known to have negative axillary nodes, no recurrence has been reported to date. CONCLUSIONS: The number of genetic abnormalities that accumulate in individual cells in primary breast cancers reflects the degree of advancement of a tumor in its genetic evolutionary sequence, and provides useful clinical prognostic information. Because follow-up duration is still relatively short, and because disease in node-negative patients tends to recur later than in node-positive patients, it is still too early to know if three measurements per cell will be sufficient to improve prognosis in node-negative disease.
