The short‐term effects of myofascial trigger point massage therapy on cardiac autonomic tone in healthy subjects Aim of the study. To investigate the effects of myofascial trigger‐point massage therapy to the head, neck and shoulder areas on cardiac autonomic tone. Background. No studies have reported on the effect of back massage on autonomic tone as measured by heart rate variability. This is especially relevant to the nursing profession, as massage is increasingly available as a therapy complementary to conventional nursing practice. Design/Methods. An experimental study in which subjects were initially placed in age‐ and sex‐matched groups and then randomized to treatment or control by alternate allocation. The study involved 30 healthy subjects (16 female and 14 male, aged 32·47 ± 1·55 years, mean ± standard error). A 5‐minute cardiac interbeat interval recording, systolic and diastolic blood pressure and subjective self‐evaluations of muscle tension and emotional state were taken before and after intervention. Autonomic function was measured using time and frequency domain analysis of heart rate variability. Results. Following myofascial trigger‐point massage therapy there was a significant decrease in heart rate (P < 0·01), systolic blood pressure (P=0·02) and diastolic blood pressure (P < 0·01). Analysis of heart rate variability revealed a significant increase in parasympathetic activity (P < 0·01) following myofascial trigger‐point massage therapy. Additionally both muscle tension and emotional state, showed significant improvement (P < 0·01). Conclusions. In normal healthy subjects myofascial trigger‐point massage therapy to the head, neck and shoulder areas is effective in increasing cardiac parasympathetic activity and improving measures of relaxation.

Effects of massage on pain and anxiety during labour: a randomized controlled trial in Taiwan Aims. To investigate the effects of massage on pain reaction and anxiety during labour. Background. Labour pain is a challenging issue for nurses designing intervention protocols. Massage is an ancient technique that has been widely employed during labour, however, relatively little study has been undertaken examining the effects of massage on women in labour. Methods. A randomized controlled study was conducted between September 1999 and January 2000. Sixty primiparous women expected to have a normal childbirth at a regional hospital in southern Taiwan were randomly assigned to either the experimental (n=30) or the control (n=30) group. The experimental group received massage intervention whereas the control group did not. The nurse‐rated present behavioural intensity (PBI) was used as a measure of labour pain. Anxiety was measured with the visual analogue scale for anxiety (VASA). The intensity of pain and anxiety between the two groups was compared in the latent phase (cervix dilated 3–4 cm), active phase (5–7 cm) and transitional phase (8–10 cm). Results. In both groups, there was a relatively steady increase in pain intensity and anxiety level as labour progressed. A t‐test demonstrated that the experimental group had significantly lower pain reactions in the latent, active and transitional phases. Anxiety levels were only significantly different between the two groups in the latent phase. Twenty‐six of the 30 (87%) experimental group subjects reported that massage was helpful, providing pain relief and psychological support during labour. Conclusions. Findings suggest that massage is a cost‐effective nursing intervention that can decrease pain and anxiety during labour, and partners' participation in massage can positively influence the quality of women's birth experiences.
Practice nurses and clinical guidelines in a changing primary care context: an empirical study
Authors: Harrison Stephen , Dowswell George , Wright John 
Published: March 2003

Background.  Practice Nurses form an increasingly large proportion of the English National Health Service primary care workforce and the delegation to them of clinical work from General Practitioners has attracted some academic attention. Central to this process are clinical guidelines, which provide the interface between the movement towards ‘evidence‐based practice’ and a range of government‐driven policy developments in primary care. Aims.  To identify the attitudes of practice nurses to clinical guidelines; to investigate the impact of guidelines on nurse/physician relationships; and to describe the impact of the changing primary care context on nurses. Methods.  We interviewed a sample of 29 Practice Nurses three times during a 16‐month period to clarify their attitudes towards guidelines, their use of guidelines in practice and their assessment of guidelines' importance. We gathered further data on organizational culture and perceptions of national reforms of primary care structures. Results.  We found that practice nurses are generally supportive of clinical guidelines. Moreover, nurses' role and influence within primary care is in a process of transition to one in which they may undertake responsibility for influencing General Practitioners' clinical behaviour so as to adhere to guidelines. Practice nurses themselves recognize and welcome this, though with some reservations. Conclusions.  Our findings support the proposal that explicit codification of the scientific basis of the work of lower paid groups may enhance their relative professional status.
Pressure area care: an exploration of Greek nurses' knowledge and practice
Authors: Panagiotopoulou Kalliopi , Kerr Susan M. 
Published: March 2003

Background. Despite a plethora of information on the prevention of pressure sores, they remain a significant problem in both hospital and community settings. The need to reduce the incidence of pressure sores has been well documented; unfortunately there is little evidence to suggest improvement. The reasons for this lack of improvement have been explored, but the picture remains unclear. While some studies have suggested that nurses have the appropriate knowledge to prevent pressure sores developing (but do not use their knowledge), others suggest that nurses' knowledge of preventive strategies is deficient. In Greece, similarly to the United Kingdom (UK), the incidence of pressure sores is high. There is currently no evidence on Greek nurses' knowledge and practice and therefore no baseline on which to build, in terms of improving practice. Aim. The purpose of this study was to explore Greek nurses' knowledge of ‘risk factors’, ‘areas at risk’ and ‘recommended preventive strategies’ in relation to pressure area care. In addition, information was sought on nurses' ‘current preventive practice’ and any barriers to ‘good practice’. Research methods. The study was exploratory and descriptive, adopting a cross‐sectional survey approach. The sample was drawn from the population of nurses working in a military hospital near Athens. The data were collected over a 4‐week period in June 2000, using a self‐completed questionnaire. Results. Although the knowledge‐base of many of the nurses was good in relation to ‘risk factors’ and ‘areas at risk’, a significant proportion were unaware that methods such as ‘massage’ and ‘donuts’ are no longer recommended. This lack of knowledge influenced practice with these methods commonly being used. In relation to barriers to good practice, a significant proportion of nurses reported that they could not access, read or understand research findings. This has obvious implications for the implementation of evidence‐based practice. Conclusion. The results of this study suggest that the knowledge and practice of participants could be improved. It is of particular concern that methods known to be detrimental were in common use. Finally, there is a need to improve the research skills of Greek nurses in order to provide them with the appropriate knowledge to use research findings.
Health promotion in palliative care: the patients' perception of therapeutic interaction with the palliative nurse in the primary care setting
Authors: Richardson Jane 
Published: March 2003

Aims.  To identify and describe palliative patients' perception of factors within the interaction with the community palliative care nurse that enhance feelings of health and well‐being, and to begin to define health promotion in relation to palliative nursing in the primary care setting. Background.  Health promotion may seem to be of little relevance in palliative care and for patients within its remit, and there is no definition of health promotion in relation to palliative care, yet therapeutic ‘new’ nursing, and its core elements of holism, egalitarianism and a humanistic approach accord with the philosophy of palliative care and are recognised as health promoting nursing practice. Design/methods.  A qualitative methodology was used. Information was obtained from 12 patients by a qualitative semi‐structured interview. Data were organised and analysed using recognised guidelines for phenomenological analysis. Findings.  The patients identified two types of therapeutic interaction with the nurse, which enhanced feelings of health and well‐being in different ways. Psychological well‐being was enhanced by the humanistic and egalitarian personal interaction with the nurse, and the professional interaction focused on the disease and addressed physical problems. Although recognizing the nurses' role in the relief of physical symptoms, the patients' perception of ‘feeling better’ generally focussed on enhancement of psychological health and well‐being. Conclusion.  For the patients, a combination of ‘new’ (therapeutic) nursing and a more traditional expert‐led approach resulted in the promotion of an enhanced sense of physical and psychological health and well‐being, and was an integral part of community palliative care nursing. Based on the study findings, the researcher offers a definition of health promotion relevant to palliative nursing in the primary care setting, which identifies that for the patients (but with caveats related to generalizability), the practice of holistically therapeutic palliative nursing is the ideal.
The work of district nurses: first assessment visits
Authors: Kennedy Catriona M. 
Published: March 2003

Background.  District nurses are the largest group of community nurses in the United Kingdom and overall responsibility for assessing and planning how patients' and families' needs are met remains an essential element of their role. Aim.  To explore the nature of the knowledge required by district nurses to carry out first assessment visits and the relationship of this to the decisions they make. Methods.  An ethnographic design was used. The sample was 11 district nurses and the principal data collection methods were participant observation and two semi‐structured interviews. The first interview, which took place immediately after the visit, was designed to explore general areas in relation to assessment and particular issues from the visit (phase 1). Following analysis of the phase 1 interview and fieldnote data, questions for the second interview were generated to facilitate further exploration and clarification of important issues that had arisen (phase 2). The second interviews were conducted approximately 1 year later and data were collected during 1997 and 1998. Findings.  The findings revealed a breadth and depth of community nursing knowledge that seemed to incorporate an amalgam of theoretical (knowing that) with practice‐based (knowing how) knowledge. The findings depict the range and scope of knowledge in use by district nurses and reflexive character of the assessment process, and challenge the use of theoretical models that remove knowledge from the context in which district nurse–patient interactions take place. Conclusion.  The information search in assessment was paced to cope with the uncertainty that existed in many of the complex multifaceted situations encountered by the district nurses. Understanding assessment as a paced process was linked to making the best judgement at the time of the visit.

The changing division of labour between nurses and nursing assistants in New Brunswick Background. In 1989, the professional nursing organization that represents nurses in New Brunswick adopted baccalaureate entry to practice in nursing. This decision coincided with a major restructuring of provincial health care. Consequently, there has been a reorganization of health care worker roles which affects nurses and nursing assistants. Aim. This paper explores the changing division of labour between nurses and nursing assistants in the province of New Brunswick, Canada. Methods. The study used archival material, from the period 1978–1990, of three nursing organizations that played a significant role in initiating baccalaureate entry to practice. Interviews with 19 key people involved in the decision to upgrade nurse education were conducted. Data from the archival material and interviews were analysed jointly. Findings. There are ongoing tensions between nurses and nursing assistants. Although nurses would like a support worker, they remain ambiguous about the role of nursing assistants in health care and which tasks should be delegated to this group. Nursing leaders are concerned about the ease with which some patient‐related tasks are moved to nursing assistants. In the past, these concerns have led nursing leaders to attempt to limit nursing assistant responsibilities through both legislative means and ways of organizing nursing labour (primary nursing). As a result of health care reforms and baccalaureate entry to practice for nurses, nursing assistant responsibilities are currently expanding. Conclusion. Upgrading nurse education, which came into effect in 1996 with the closure of diploma schools in New Brunswick, is likely to entrench the role of nursing assistants in health care because of the economic value of their work during a period of restructuring and rationalization of health care.
How can a pelagic seabird provision its chick when relying on a distant food resource? Cyclic attendance at the colony, foraging decision and body condition in sooty shearwaters
Authors: Weimerskirch Henri 
Published: March 2003

1.  Sooty shearwaters are abundant in waters too distant from their colonies to account for the observed average frequency with which the chicks are fed. This, and the unexplained cyclic pattern of attendance at their colonies, have led to contradictory interpretations related to evolution of the extreme life histories of pelagic seabirds and their relationship with the marine environment. 2.  Study of the provisioning behaviour of individual parent sooty shearwaters indicates that they can rely on productive distant waters, probably 1550. km away, to build up their body reserves and to provision their chick. These long foraging trips on average last 11. days and account for 84% of the foraging time. 3.  Birds use this stored energy to cover the costs of performing several successive foraging trips of short duration in nearby less productive waters. These brief trips double the energy flow to the chick and take only 16% of the foraging time but are at the expense of adult body condition, i.e. there is a net energy loss. Foraging successively with short and long trips allows parents to increase by 20% the energy flow to the chick over what it would get if foraging was exclusively in distant waters. 4.  The results suggest that maximal fitness in this pelagic seabird is not achieved by maximization of foraging efficiency but is the result of a trade‐off system whereby at some stages birds forage with net energy losses. The decision to feed close to or far from the colonies, i.e. to allocate to the chick or to store body reserves, is not related to any endogenous rhythm, nor to the nutritional status of the chick, nor to the length of the previous foraging trip. Rather, it is under the sole control of adult body condition, with the possible existence of a threshold body mass around 750 g. Thus, adult body mass plays a central role in foraging decisions, linking foraging and allocation. 5.  The synchronized return of foraging birds every 2. weeks is not due to environmental factors. By modelling attendance patterns with an increasing variance in the foraging routine, it is shown that the periodicity of feeding times is retained throughout the chick rearing period, with a cyclicity of 14. days. This result indicates that cyclic attendance at the level of the whole colony is an emergent property of the two‐fold foraging strategy of individual adults. 6.  One main consequence of this system appears to be a reduction in competition close to the breeding grounds and this may help explain the existence of huge populations of sooty and short‐tailed shearwaters that rely on distant food resources.
Small mammals cycles in northern Europe: patterns and evidence for a maternal effect hypothesis
Authors: Inchausti Pablo , Ginzburg Lev R. 
Published: March 2003

1.  Voles undergo pronounced oscillations over periods of 3–5 years in northern Europe. A latitudinal gradient of cycle periods and amplitudes has been reported for Fennoscandia, with periods and amplitudes increasing towards northern latitudes. 2.  This study formulates a discrete time model based on maternal effects to explain the density fluctuation patterns of microtine rodents. The phenotypic transmission of quality from mothers to offspring generates delayed density dependence, which produces cyclic behaviour in the model. 3.  The dynamic patterns predicted by the maternal effect model agree with data. We conclude that the maternal effect hypothesis is a plausible, parsimonious explanation for vole‐density cycles in northern Europe.
Explaining the latitudinal gradient anomaly in ichneumonid species richness: evidence from butterflies
Authors: SIME KAREN R. , BROWER ANDREW V. Z. 
Published: March 2003

1.  Despite the profusion of Lepidoptera and other potential hosts in the tropics, the Ichneumonidae are not more species‐rich in the lowland tropics than in temperate communities. Alternate but partially complementary hypotheses emphasizing resource fragmentation, predation, or chemical defence have been proposed to explain this paradox. 2.  Because different diversity gradients occur in the various subgroups of the Ichneumonidae, as well as among their hosts, general explanations are unlikely to account for this ‘anomalous diversity.’ Hypotheses of ecological causation are best tested at the taxonomic level where the pattern of interest applies. 3.  Phylogenetic trends in the distribution, abundance, and palatability of butterflies (Papilionoidea), a group that increases dramatically in species richness towards the tropics, are presented as a case study for evaluating hypotheses of parasitoid species richness. Evidence is presented that supports the ‘nasty host hypothesis’ as an explanation for the lack of diversity of associated parasitoids. 4.  An examination of hypotheses and the approaches used to test them suggests that the nasty‐host hypothesis is best supported by the limited evidence available, while evidence in favour of other hypotheses is either lacking or ambiguous. In particular, use of the koinobiont/idiobiont dichotomy and parasitoid assemblage‐size comparisons may result in contradictory conclusions.
Regulation of food provisioning in the Antarctic petrel; the importance of parental body condition and chick body mass

1. Two hypotheses may explain how long‐lived seabirds regulate the food provisioning to their chick. The fixed level of investment hypothesis states that the parents provide food for their chick according to an intrinsic rhythm, independent of their chick's need. The flexible investment hypothesis states that the parents adjust their food provisioning both according to their chick's and their own need. 2. We tested how the Antarctic petrels adjust the food‐provisioning according to their own body condition or to their chick's need. First, we selected parents in poor and good body condition. Then we gave all parents randomly a chick of different body mass, but of the same age. We then measured the chicks daily until they were fed for the first time after swapping. 3. Parents in good body condition at hatching were more likely to produce a chick that was still alive 9 days after hatching than parents in poor body condition. Chick body mass at day 9 and at the end of the guarding period was positively related to the mean body condition of the parents at hatching. 4. The meal size provided by parents in good body condition was larger than that provided by parents in poor body condition. Parents in good body condition delivered more food to small than to large chicks, whereas no such relationship was found among parents in poor body condition. 5. Our results suggest that the Antarctic petrel parents adjust the amount of food delivered to their chick according to both the chick's need and their own body condition, and that the ability to respond to the chick's need is dependent upon their own body condition.
The relative role of density‐dependent and density‐independent survival in the life cycle of Atlantic salmonSalmo salar
Authors: Jonsson N. , Jonsson B. , Hansen L. P. 
Published: March 2003

1. Density‐dependent factors appeared important for the survival of juvenile Atlantic salmon in the River Imsa whilst density‐independent factors were more important for the older fish at sea. In fresh water, density dependence was indicated by a stock−recruitment relationship with increasing loss‐rates from eggs to smolts and from eggs to adults as egg density increased. 73% of the loss‐rates were explained by variation in egg density. At sea, density independence was indicated by the lack of a significant relationship between loss‐rates and smolt densities.2.The relationship between smolt density and initial egg density was best described by an asymptotic ‘Cushing’ type relationship with a plateau at densities higher than approximately 60 000 eggs for the total river areas of 10 000 m2. The number of smolts developed from the eggs spawned varied between 350 and 2400.3.The relationship between smolt biomass in wet mass (kg 10 000 m−2) or energy (kJ 10 000 m−2) and the amount of salmon eggs in the River Imsa increased asymptotically. Annual smolt biomass ranged from 13 to 88 kg 10 000 m−2, or 66 000 and 431 000 kJ 10 000 m−2. Variation in egg density accounted for approximately 45% of the variation in smolt biomass (mass or energy).4.Total wet mass and energy of adults (kg 10 000 m−2and kJ 10 000 m−2) produced in relation to the amount of eggs at the start of the year‐class, were not significantly correlated, due to a high variation among years. The biomass of adults ranged from 73 kg 10 000 m−2to 655 kg 10 000 m−2and in energy from 370 000 kJ 10 000 m−2to 3 270 000 kJ 10 000 m−2.5.Total adult biomass (adults caught at sea and in rivers) and the returning adults to the River Imsa in mass or energy were correlated with the size of the smolt cohort from which they originated. Yearly total adult biomass ranged between 240 and 3711 kg 10 000 m−2, when the number of smolts ranged from 397 to 2751, respectively. The biomass of adults returning to the River Imsa was between 59 and 614 kg, produced from between 672 and 1621 smolts.
