Randomised feasibility study to compare the use of Therabite® with wooden spatulas to relieve and prevent trismus in patients with cancer of the head and neck.

Our aim was to compare the efficacy of the Therabite® jaw motion rehabilitation system (Atos Medical) with that of wooden spatulas to relieve and prevent trismus in patients who have had radiotherapy for stage three and four oral and oropharyngeal cancer. Secondary aims were to assess the feasibility and the impact of exercise on health-related quality of life (QoL), and the use of health services after treatment. We designed a randomised, open-label, controlled, three-centre feasibility study to compare the effectiveness and cost of the Therabite® and wooden spatulas. We studied compliance with exercises and health-related QoL, assessed cost using three health economics measures, and conducted semistructured interviews with patients. Patients were randomised into two groups: the Therabite® group (n=37) and the wooden spatula group (n=34). All patients had some sense of jaw tightening before the study started. Mean mouth opening after six months increased in both groups, but the difference between the groups was not significant (p=0.39). Completion rates for the three economic measures were good. There was no significant difference between the two groups in frequency of contact with care services or in QoL. Exercises during and after radiotherapy can ameliorate trismus in patients with stage three and four oral and oropharygeal cancers, but differences between groups in efficacy, compliance, QoL, or use of hospital or community health services, were not significant.

Assessing parenting capacity: are mental health nurses prepared for this role?

Mental health nurses in the UK are involved in the assessment of the parenting capacity of mothers with a serious mental illness in psychiatric facilities. There is evidence that child and family social workers, as the frontline professionals in safeguarding children, rely heavily on the mental health parenting assessment. Parenting assessments have potentially major implications for mother and baby and can lead to the separation of mother and baby. However, there is little or no provision for mental health nurses to undertake this role. In the UK, as in many other countries, there is currently no data as to which psychiatric facilities are conducting parenting assessments nor about the quality of the assessment. There are significant tensions for mental health nurses undertaking parenting assessments and there is no specific training for the role. This paper challenges existing practice, highlights the need for an audit of the current services and recommends the development of a recognized training programme.

Improving the evidence base in palliative medicine: a moral imperative.

UNLABELLED: The difficulties of undertaking good quality effectiveness research in palliative medicine are well documented. Much of the ethical literature in this area focuses on the vulnerability of the palliative care population. It is clear that a wider ethical approach will need to be used to justify research in the terminally ill. Some themes of ethical thought are underutilised in considering the ethics of palliative care research. Three arguments to justify the need for effectiveness research in palliative care should be highlighted: (1) there is evidence of an untapped altruism amongst the population of palliative care patients who would be keen to be involved in such research; (2) traditional Aristotelean and Thomistic virtue ethics would point to the need to gain knowledge in and of itself, but especially in palliative medicine for the benefit of PATIENTS: virtue also accrues in the acquisition of a stock of research experience which in turn makes further research feasible; (3) most compellingly, justice would dictate that palliative treatments are effective, that futile or useless treatments are avoided and that patients are not party to "n of 1" trials by default. The current state of the evidence base of effectiveness in palliative care leads us to the uncomfortable position where patients are in precisely the position of being unwitting participants in "n of 1" clinical trials by default, without their explicit consent.

Multiprofessional clinical supervision: challenges for mental health nurses.

Recent reform and developments in mental health care provision have increasingly espoused the value of multiprofessional teamwork in order to ensure that clients are offered co-ordinated packages of care that draw on the full range of appropriate services available (DoH 1999a; DoH 2000). Supervision in some form is seen as a key part of all professional practice to provide support to practitioners, enhance ongoing learning, and, to a greater or lesser degree, offer some protection to the public (Brown & Bourne 1996, UKCC 1996). Clinical supervision has gained increasing momentum within the nursing profession, but to a large extent this has been within a uni-professional framework -- nurses supervising other nurses. This paper seeks to explore the ways in which multiprofessional working and clinical supervision interlink, and whether supervision across professional boundaries might be desirable, possible, and/or justifiable. Whilst our own view is that multiprofessional supervision is both possible and desirable, we seek to open up a debate, from our perspective as mental health nurses, about some of the issues related to the concept. Our motivation to explore this topic area emanates from our experiences as supervisors to colleagues within multiprofessional teams, as well as the experiences of those attending supervisor training courses. Following a brief overview of the development of clinical supervision in mental health care and recent policy guidelines, some models of clinical supervision are reviewed in terms of their suitability and applicability for multiprofessional working.

Non-compliance and professional power.

The non-compliance of patients with prescribed treatments is considered as a barrier to effective health care. Non-compliance has implications for the health of patients, effective use of resources and assessments of the clinical efficacy of treatments. Research into non-compliance has increased over the last 30 years. This seems to indicate that it is seen as an important area of concern for all health care professionals. Definitions of non-compliance are problematic, as are methods of assessment of its nature and frequency. Many factors which may account for non-compliance have been proposed, as well as methods to improve compliance. Research into these factors however, mainly based on a positivist epistemology, has failed to provide any conclusive answers to the problem. Sound clinical reasons are suggested as the basis for the increase in interest in non-compliance. It is contended, however, that it is not only these reasons that account for the identification of non-compliance as a problem. Non-compliant behaviour is seen as problematic, because it contravenes professional beliefs, norms and expectations regarding the 'proper' roles of patients and professionals. These have formed the basis of an ideology that views patients as passive recipients of health care. It has led to an inherent tendency to 'blame' the patient and view non-compliance as irrational and deviant. The professional view of non-compliance as irrational, is exemplified in the case of individuals with mental illness, where there are inherent assumptions that non-compliance can be seen primarily as a symptom of illness. This denies the legitimacy of patient choice, and has led to attempts to control compliance via suggested legislative measures. Serious moral and ethical problems arise from such measures, and can be seen as the ultimate legitimization of an ideology of non-compliance. The maintenance of professional power and control is suggested as central to the debates surrounding non-compliance. The ideological assumptions underpinning the concept of non-compliance need questioning, and a re-conceptualization of the roles of patients and professionals is required. This must involve a view of patients as active participators in their own health care. Research based on an interpretative epistemology, aimed at understanding individual action, rather than control, would seem a more appropriate model to pursue.

Separation and characterization of cholesteryl oxo- and hydroxy-linoleate isolated from human atherosclerotic plaque.

In previous work we demonstrated that up to 30% of cholesteryl linoleate in homogenates of advanced human plaque samples is present in oxidized forms. Here we show that the material from plaque hexane extracts which co-elutes with cholesteryl hydroxy-linoleate on reversed phase HPLC (Anal Biochem 1993;213:79), is composed of several isomers of cholesteryl hydroxy- and cholesteryl oxo-octadecadienoate. Enzymatic hydrolysis and measurement of liberated cholesterol and disappearance of the esters revealed that almost all of the material consisted of unoxidized cholesterol esterified to oxidized derivatives of octadecadienoate. Semi-preparative reversed-phase HPLC was used to obtain sufficient quantities of this co-eluting material to undertake normal phase HPLC separation of these components. The nature of such separated and isolated compounds was identified, by co-chromatography with authentic standards, UV spectroscopy and chemical ionization and electron impact mass spectrometry, as cholesteryl hydroxy- and cholesteryl oxo-octadecadienoate. These oxidized fatty acids have been observed previously in plaque, in agreement with our new unambiguous demonstration of their presence as cholesteryl esters. The application of the methods described for the separation of the various forms of oxidized cholesteryl octadecadienoate may aid mechanistic studies of in vitro and in vivo lipoprotein lipid oxidation.

Oral nifedipine for the treatment of patients with severe hypertension.

Ten mg of nifedipine was administered to 19 patients with severe hypertension (mean blood pressure 187 +/- 17/122 +/- 12 mm Hg) without intensive care monitoring. Patients were instructed to bite and swallow the contents of the capsule. Blood pressure declined significantly to a mean of 149 +/- 17/92 +/- 10 mm Hg. No adverse side effects or hypotension occurred. Ten patients required an additional dose 30 to 60 minutes after the initial dose. Mean heart rate increased from 79 to 95 beats per minute without symptomatic consequences. Laboratory parameters measured before and after the four-hour study did not change significantly, although peripheral renin activity rose transiently. Urinary sodium excretion increased 43 percent over four hours after therapy in three patients in whom it was measured. Cardiac output, which was measured noninvasively in seven patients, rose nonsignificantly whereas systemic vascular resistance declined from 2,070 dynes/second/cm-5 to 1,271 dynes/second/cm-5 (statistically significant difference) in 20 minutes. These results indicate that oral nifedipine, when bitten and swallowed, effectively lowers blood pressure in patients with severe hypertension without the occurrence of adverse side effects or hypotension. Oral nifedipine may be used safely in an outpatient setting when urgent intervention is required.
