Trusting patients, trusting nurses

Abstract  The general expectation that patients should be willing to trust nurses is rarely explored or challenged despite claims of diminishing public trust in social and professional institutions. Everyday meanings of trust take account of circumstance and suggest that our understanding of what it means to trust is contextually bound. However, in the context of health care, to trust implies a particular understanding which becomes apparent when abuses of this trust are reported and acknowledged as scandals. The predominant assumption in the literature that trust is something that occurs between equally competent adults cannot explain trust in nursing precisely because of the unequal power relationships between patients on the one hand and healthcare professionals on the other. Moreover, the tendency to conflate terms such as trust, reliance, confidence and so on suggests that confusion permeates discussions of trust in nursing. In this paper, I argue in support of Annette Baier's requirement of good will (or lack of ill will) as the essential feature of trust, and outline how this account (i) enables us to make the necessary distinctions between trust on the one hand and 'trust pretenders' on the other; and (ii) lays the foundations for understanding trust in relationships, such as those between patients and nurses, where power differentials exist.     

Developing nurse practitioners to develop practice: the experiences of nurses working on a Nursing Development Unit

Aim To elicit nurses' accounts of their involvement with nursing research and their interpretations of the meaning of these projects for their practice.
Background The links between research and practice development in health care are poorly understood and require further exploration in the light of the emerging research and development agenda within the National Health Service.
Methods Semi-structured interviews were conducted with 15 qualified nurses working on a Nursing Development Unit. The interviews were tape recorded, transcribed and analysed thematically.
Findings Data analysis identified two distinct groups—a core group of nurses actively engaged in the research projects and a peripheral group involved in data collection. The characteristics of the core group mirror the characteristics of those involved in non-research-based practice development activities.
Conclusions Engaging in research activities does not always result in the development of practice, however, there appears to be a link between practice development and critical thinking.     

Angiomyolipoma of the kidneys

59 angiomyolipomas were studied: immunohistochemistry (IHC) was used in 24 cases, electron microscopy (EM) in 6 cases. 57 tumors had a typical structure, 2 did not contain fat component. Premelanosomes were found by EM in one tumor. Smooth muscle actin was found in all tumor cells. Involvement of lymph nodes was observed in 2 patients. Histogenesis of this tumor is discussed.     

Morphochemical characteristic of rat brain structures after exposure to delta-sleep inducing peptide following long-term amphetamine administration

The aim of this work, that was carried out using Wistar rats, was to characterize the response of neurons of different morphofunctional types to amphetamine administration and to study the possibility of correction of these changes by delta-sleep inducing peptide (DSIP). Single intraperitoneal injection of 60 microg/kg of DSIP following a long term amphetamine administration (2.5 mg/kg for 3 weeks) was shown to result in normalization of brain metabolism, that was disturbed by the drug. The correcting DSIP effect was found in rat brain structures judging by the parameters of the state of proteins in neurons of sensomotor cortex and caudate nucleus and by the activity of enzymes of neurotransmitter metabolism, such as type A and B monoamine oxidases and acetylcholine esterase, that was determined in subfractions of the same brain structures. DSIP modulating effect in phenamine stereotypy supports its role as an adaptogen of intercenter relations in CNS pathology.     

Morphology of the microencapsulated form of measles vaccine based on pH-dependent polymers

Morphology of microparticles of the microencapsulated measles vaccine was studied by cryofractography, transmission electronic microscopy and by atomic force microscopy; co-polymers of polyacrylic acid and of sodium-alginate (spermidine) complexes were used as the matrix. The different-composition microcapsules had clear-cut borders and a certain range of sizes; but they were different in morphology, and their structures and densities varied identically with regard for a medium acidity, which is apparently preconditioned by some conformation-type alterations of matrix molecules. The studied preparations can, probably, protect the viral material in the stomach aggressive medium and release the material to ensure its contact with the intestine lymph tissue; thereof, they can be referred to as promising for further study of mucosal vaccines.     

Detection of the circulation of Crimean-Congo hemorrhagic fever virus in the piedmont steppes of the North Caucasus

The laboratory verified cases of Crimean-Congo hemorrhagic fever (CCHF) in the piedmont steppes of the North Caucasus (Malgobeksky District, Republic of Ingushetia) are first described. The source of the first infection was Ixodidae ticks; three subsequent sources were contacts with the bloody discharges from patients. CCHF virus genome was detected in the blood of the cattle from an epidemic focus and in the pools of the Ixodes ticks Haemaphysalis parva Neum., 1897 and Boophilus annulatus Say, 1821, taken from cattle. The problem of including the piedmont steppes of the North Caucasus into the CCHF nosological area is discussed.     

Morphological and functional changes in spinal ganglion neurons after epidural clopheline administration

The aim of this chronic experimental study performed in 16 dogs was to determine the effect of epidural infusion of 0.01% clopheline solution on the morphological and histoenzymological characteristics of spinal ganglion neurons. Daily infusions of clopheline at the dose of 15 mg/kg for 14 days caused a decrease in capillary permeability in the spinal ganglia at the injection site and its increase in the intact areas. This finding suggests the changes in the activity of the microcirculatory bed with a disturbed interaction in capillary-neuron system. Analysis of morphometric parameters has demonstrated the presence of some functional and reversible dystrophic changes in spinal ganglion neurons, which were associated with epidural infusion of both clopheline and isotonic solution of sodium chloride. Determination of the activity of oxidation-reduction enzymes, which reflect the course of aerobic and anaerobic processes in spinal ganglion neurons, has shown no significant differences between the groups of animals infused with or isotonic solution of sodium chloride. In conditions of chronic experiment no significant variations were found in RNA content in ganglionic cells at and outside the sites of infusion of clopheline and of isotonic solution of sodium chloride.     

Iliac mucosa changes in late periods after total colectomy in patients with syndromes of gastro-intestinal polyposis

We studied follow-up iliac mucosa biopsies from 11 patients with juvenile polyposis and 4 patients with familial adenomatous polyposis who had undergone total colectomy with mucosal proctoectomy with creation of straight ileoanal anastomosis. The biopsies that have been taken from the posterior wall of the terminal ileum show incomplete and focal neocolonic transformation of iliac mucosa. Nevertheless, in most cases iliac mucosa preserved its architectural and histochemical characteristics. Chronic inflammation in iliac mucosa is not typical for patients with polyposis.
