Differences in understanding of specialist palliative care amongst service providers and commissioners in South London.

This paper describes a study that sought to identify service providers' and commissioners' understanding of specialist palliative care within the context of changing service provision in one area of South London. Using a formative evaluation framework, we examined the views of 44 providers and commissioners from statutory and voluntary health and social care services about their understanding of specialist palliative care services and, in particular, the remit of current service provision delivered by a Marie Curie Centre. Face-to-face audiotaped semi-structured interviews were conducted. A qualitative thematic analysis highlighted a number of issues including a lack of consensus about definitions of palliative care, ambivalence about referral procedures, and a lack of role clarity between specialist and generalist palliative care providers. The study took place within the real world context of changing services and economic pressures. This raises methodological issues about how services are evaluated and what terminology is used to describe end-of-life care. The study findings confirm that confusion about terminology and referral criteria remain major issues for clinical workers and organizations seeking to access services.

Eating soya improves human memory.

RATIONALE: Soya foods are rich in isoflavone phytoestrogens with weak agonist activity at oestrogen receptors. Oestrogen treatment has been found to improve memory in men awaiting gender reassignment and in post-menopausal women. OBJECTIVE: To examine the effects of supervised high versus low soya diets on attention, memory and frontal lobe function in young healthy adults of both sexes. METHODS: Student volunteers were randomly allocated to receive, under supervision, a high soya (100 mg total isoflavones/day) or a low soya (0.5 mg total isoflavones/day) diet for 10 weeks. They received a battery of cognitive tests at baseline and then after 10 weeks of diet. RESULTS: Those receiving the high soya diet showed significant improvements in short-term (immediate recall of prose and 4-s delayed matching to sample of patterns) and long-term memory (picture recall after 20 min) and in mental flexibility (rule shifting and reversal). These improvements were found in males and females. In a letter fluency test and in a test of planning (Stockings of Cambridge), the high soya diet improved performance only in females. There was no effect of diet on tests of attention or in a category generation task. Those on the high soya diet rated themselves as more restrained and, after the tests of memory and attention, they became less tense than did those on the control diet. CONCLUSIONS: Significant cognitive improvements can arise from a relatively brief dietary intervention, and the improvements from a high soya diet are not restricted to women or to verbal tasks.

Implications of social isolation during cancer treatment. The implications of residence away from home during cancer treatment on patients' experiences: a comparative study.

With the centralisation and specialisation of cancer services, patients may have to travel considerable distances and stay away from their homes during treatment. This paper describes a comparative study that sought to identify the effects on patients of receiving chemotherapy and/or radiotherapy away from their homes, families and social support networks. Eighty four cancer patients treated in Southampton (42 from Guernsey and 42 from Southampton) agreed to participate in a structured interview and a standardised measure of social support. There were few differences in terms of satisfaction with services between Guernsey patients who stayed away from home during treatment and Southampton patients who lived at home. Counter-intuitively, Guernsey patients perceived themselves to have better social support.

The impact of travel on cancer patients' experiences of treatment: a literature review.

This literature review aims to identify the impact of travel on cancer patients' experiences of treatment. With centralization of cancer services, patients may have to travel considerable distances from their homes and families, to receive specialist cancer treatment. Centralization of cancer services may have advantages in terms of concentrating clinical expertise, enhancing the range of ancillary facilities and rationalising the provision of expensive specialist equipment, but it is not known to what extent patients are affected by additional travel and the prospect of separation from their social networks. A systematic literature search using MEDLINE, SSCI, SOCA and PSYCHLIT, identified 11 relevant studies from six countries. The review showed a paucity of research on the implications of receiving cancer treatment far from home. Most studies can be criticised on methodological grounds. The evidence that travel distance and difficulty increases psychological distress, and reduces compliance with treatment and take up of treatment is largely inconclusive. However, travel to cancer treatment is described as inconvenient and a practical hardship for many patients. It may be perceived, or experienced as, a barrier to treatment. Future studies should evaluate the impact of travel to treatment on quality of life and perceived social support.

'Someone to talk to' and 'pain control': what people expect from a specialist palliative care team.

This paper presents a qualitative analysis of a subsample of data from a larger investigation into general practitioner referrals to specialist palliative care services (SPCS). The aim was to identify the expectations and perceptions of patients with advanced cancer and their relatives. Twenty-nine individuals were interviewed (18 patients, 11 relatives). Qualitative analysis of the interview transcripts was undertaken using an approach based on interpretative phenomenological analysis. The results indicated that SPCS were perceived as providing psychosocial services, characterized as 'support' and 'someone to talk to'. SPCS were expected to have 'expertise in symptom control', particularly in relation to pain management. The study demonstrated that patients' and relatives' expectations of a referral to SPCS were of psychosocial support and symptom control. It is argued that the implications of this restricted view of SPCS may mean that other salient concerns are not raised by patients and relatives.

Improving palliative care services: a pragmatic model for evaluating services and assessing unmet need.

Evaluating local palliative care services and identifying gaps in services for patients are crucial to the development of services which enable people to die at home in a well-supported environment. A review of the local strategy for providing respite and support services for palliative care patients and their carers was carried out in one area of south-east England. The review comprised four elements: identification of services available; interviews with provider 'stakeholders'; interviews with patients and carers; questionnaire survey of general practitioners and district nurses. The findings and outcome are described. It is suggested that this approach could be adopted by health authorities to form one part of a comprehensive system of needs assessment. Alternatively, it could be used by groups of providers to evaluate existing services and to identify potential improvements to services. Advantages and disadvantages of the approach for both commissioners of such reviews and those carrying them out are discussed.

Effect of extract of Rhazya stricta, a traditional medicinal plant, on rat brain tribulin.

Rhazya stricta leaves, which have both antidepressant and sedative properties in animal models, are widely used in folk medicine in the Arabian peninsula. In this study, the effects of oral administration of leaf extracts on rat brain tribulin levels [endogenous monoamine oxidase (MAO) A and B inhibitory activity], were determined. In an acute study, low doses brought about an increase in MAO A inhibitory activity, while intermediate doses caused a significant reduction. The highest doses had no significant effects on activity. There were no significant effects on MAO B inhibitory activity at any dose. Subchronic administration (21 days) caused a significant decrease in MAO A inhibitory activity, most prominent at low dosage, and an increase in MAO B inhibitory activity. Acute intramuscular administration also resulted in a similar pattern. Such paradoxical effects were at least partially explained when different extracts of the leaves were used; a weakly basic chloroform fraction caused an increase in MAO A inhibitory activity, whereas butanol extracts brought about a decrease. These fractions had no significant effects on MAO B inhibitory activity. The findings show that Rhazya stricta leaves contain at least two different components that affect MAO inhibitory activity in opposite directions. It may be that the antidepressant and sedative actions of the plant are explicable in terms of these different components.

Red wine is less stress reducing than vodka; no differences in neuroendocrine challenge test.

Red wine, like the drugs reserpine and fenfluramine, causes the release of 5-hydroxytryptamine (5-HT) from storage sites in vitro. This study used a neuroendocrine challenge test design to determine whether the parallel between red wine and these drugs can be extended to central actions in healthy volunteers. Vodka diluted to an equal alcohol content was used as a control. No significant differences were observed between the groups in plasma cortisol, plasma prolactin or in temperature levels. Thus no evidence was obtained for a central 5-HT releasing action by red wine. Self-rating stress and arousal questionnaires were also given. No differences were found in arousal. However whereas vodka had a clear effect in reducing stress, red wine did not. This suggests that red wine does have psychoactive properties independent of its alcohol effects.

A selective review of the literature on nurse-patient communication: has the patient's contribution been neglected?

The literature on nurse-patient communication is selectively reviewed. Previous research has been critical of the quality and quantity of nurse-patient communication, describing it as brief and superficial. Nurses are depicted as controlling and restricting the course and topics of conversations with patients. Communication skills training for nurses has been advocated as a solution for this apparent deficit. In this paper it is argued that research has over-emphasized nurses' roles in nurse-patient communication, particularly their communication skills. The patients' contribution to the content and organization skills. The patients' contribution to the content and organization of nurse-patient communication has been largely ignored. Assumptions have been made about nurses' and patients' intentions and motives during nurse-patient conversations, but the participants, particularly patients, are rarely asked for their views. There has been a tendency to view nurse-patient communication in terms of isolated excerpts of conversation. When environmental and organizational factors are included, it is their effect on nurses' communication capability, not the patients', that are the interest. It is suggested that future research consider both patients' and nurses' contributions to nurse-patient communication.

Dietary migraine: recent progress in the red (and white) wine story.

The concept of dietary migraine as a clinical entity remains controversial. We review here such objective evidence that has been put forward for its existence. Red wine, in particular, is commonly alleged to initiate attacks in susceptible individuals. We discuss how some of its recently described pharmacological properties might trigger off the sequence of events leading to migrainous headache.
