Isoflurane produces antidepressant effects and induces TrkB signaling in rodents

A brief burst-suppressing isoflurane anesthesia has been shown to rapidly alleviate symptoms of depression in a subset of patients, but the neurobiological basis of these observations remains obscure. We show that a single isoflurane anesthesia produces antidepressant-like behavioural effects in the learned helplessness paradigm and regulates molecular events implicated in the mechanism of action of rapid-acting antidepressant ketamine: activation of brain-derived neurotrophic factor (BDNF) receptor TrkB, facilitation of mammalian target of rapamycin (mTOR) signaling pathway and inhibition of glycogen synthase kinase 3β (GSK3β). Moreover, isoflurane affected neuronal plasticity by facilitating long-term potentiation in the hippocampus. We also found that isoflurane increased activity of the parvalbumin interneurons, and facilitated GABAergic transmission in wild type mice but not in transgenic mice with reduced TrkB expression in parvalbumin interneurons. Our findings strengthen the role of TrkB signaling in the antidepressant responses and encourage further evaluation of isoflurane as a rapid-acting antidepressant devoid of the psychotomimetic effects and abuse potential of ketamine.

KCC2 interacts with the dendritic cytoskeleton to promote spine development

The neuron-specific K-Cl cotransporter, KCC2, induces a developmental shift to render GABAergic transmission from depolarizing to hyperpolarizing. Now we demonstrate that KCC2, independently of its Cl(-) transport function, is a key factor in the maturation of dendritic spines. This morphogenic role of KCC2 in the development of excitatory synapses is mediated by structural interactions between KCC2 and the spine cytoskeleton. Here, the binding of KCC2 C-terminal domain to the cytoskeleton-associated protein 4.1N may play an important role. A more general conclusion based on our data is that KCC2 acts as a synchronizing factor in the functional development of glutamatergic and GABAergic synapses in cortical neurons and networks.

Cancer patients' views and experiences of participation in care and decision making

The purpose of this study was to explore the views and experiences of adult cancer patients about patient participation in care and decision making and the preconditions for this participation. The data were collected by means of focused interviews; in addition the patients completed depression and problem-solving instruments. The sample comprised 34 cancer patients from the haematological and oncological wards of one university hospital in Finland. The results revealed considerable variation in the patients' views on their participation in care and decision making. Some of the patients understood participation either in terms of contributing to the decision making or in terms of expressing their views on treatment options. Some considered that their participation in care was impossible. Patient participation in care and decision making was promoted by good health, access to information, assertiveness, good interactive relationships with nurses and physicians, and encouragement by nurses and physicians to participate. Factors restricting such patient participation were poor health, ignorance, anxiety, age, time pressures of staff, lack of time, high staff turnover and poor interactive relationships. With regard to participation in medical decision making, the patients were divided into three groups: (1) active participants (n = 7), (2) patients giving active consent (n = 9), and (3) patients giving passive consent to medical decisions (n = 18).

The role of ECM molecules in activity-dependent synaptic development and plasticity

Growth and guidance of neurites (axons and dendrites) during development is the prerequisite for the establishment of functional neural networks in the adult organism. In the adult, mechanisms similar to those used during development may regulate plastic changes that underlie important nervous system functions, such as memory and learning. There is now ever-increasing evidence that extracellular matrix (ECM)-associated factors are critically involved in the formation of neuronal connections during development, and their plastic changes in the adult. Here, we review the current literature on the role of ECM components in activity-dependent synaptic development and plasticity, with the major focus on the thrombospondin type I repeat (TSR) domain-containing proteins. We propose that ECM components may modulate neuronal development and plasticity by: 1) regulating cellular motility and morphology, thus contributing to structural alterations that are associated with the expression of synaptic plasticity, 2) coordinating transsynaptic signaling during plasticity via their cell surface receptors, and 3) defining the physical parameters of the extracellular space, thereby regulating diffusion of soluble signaling molecules in the extracellular space (ECS).

Kainate receptors and the induction of mossy fibre long-term potentiation

There is intense interest in understanding the molecular mechanisms involved in long-term potentiation (LTP) in the hippocampus. Significant progress in our understanding of LTP has followed from studies of glutamate receptors, of which there are four main subtypes (alpha-amino-3-hydroxy-5-methyl-4-isoxazole-propionic acid (AMPA), N-methyl-D-aspartate (NMDA), mGlu and kainate). This article summarizes the evidence that the kainate subtype of glutamate receptor is an important trigger for the induction of LTP at mossy fibre synapses in the CA3 region of the hippocampus. The pharmacology of the first selective kainate receptor antagonists, in particular the GLU(K5) subunit selective antagonist LY382884, is described. LY382884 selectively blocks the induction of mossy fibre LTP, in response to a variety of different high-frequency stimulation protocols. This antagonist also inhibits the pronounced synaptic facilitation of mossy fibre transmission that occurs during high-frequency stimulation. These effects are attributed to the presence of presynaptic GLU(K5)-subunit-containing kainate receptors at mossy fibre synapses. Differences in kainate receptor-dependent synaptic facilitation of AMPA and NMDA receptor-mediated synaptic transmission are described. These data are discussed in the context of earlier reports that glutamate receptors are not involved in mossy fibre LTP and more recent experiments using kainate receptor knockout mice, that argue for the involvement of GLU(K6) but not GLU(K5) kainate receptor subunits. We conclude that activation of presynaptic GLU(K5)-containing kainate receptors is an important trigger for the induction of mossy fibre LTP in the hippocampus.

Clinical judgement and information seeking by nurses and physicians working with cancer patients

This study examined and compared the processes of information collection and clinical judgement by nurses (n=107) and physicians (n=27) working with cancer patients. The data was collected in two university hospitals by means of a computer-simulated case description and the thinking-aloud method. Data interpretation was based on SPSS statistical software and the method of content analysis. Statistical differences between the two groups were tested with non-parametric Kruskal-Wallis Anova or the Mann-Whitney U-test. The Wilcoxon test was applied in pairwise comparisons. Independent questions were analysed by cross-tabulation and Pearson's chi(2). According to the results nurses and physicians apply different approaches to clinical judgement and problem-solving. On the basis of the status statement they received in the program both groups pointed to similar problems and sought a great deal of additional information. However the type of information required was different in the two groups. There were also significant differences in the knowledge base applied for purposes of clinical judgement: nurses tended to rely on personal knowledge, physicians on theory. Physicians were able to identify their patient's major clinical problems, but nurses had more difficulty doing this. On the other hand, nurses took a broader view on the general well-being of patients than physicians did.

Clinical pathway of elderly persons with lowered mood in the health care services

Elderly persons with mild depression are notable consumers of somatic health services. This study describes the typical clinical pathway including institutional care of two groups, depressed and non-depressed elderly persons, in different stages of the health care system, and compares possible changes in the use of health care services between the two groups. We also compare differences in morbidity and mortality between depressed and non-depressed persons. The depressed group of 50 persons in our follow-up study were selected randomly from among those persons who were diagnosed as having symptoms of depression, as shown in the Zung Self-Rating Depression Scale (n = 109). Persons (n = 50) who were not diagnosed as suffering from depression and who showed no signs of cognitive impairment (n = 833) were likewise chosen at random as a control group. We found that people suffering from symptoms of depression utilized institutional care, home health care and the outpatient clinics more than non-depressed people. Depressed people were more likely to suffer cardiovascular (p < 0.023) and pulmonary diseases (p < 0.04) than non-depressed controls. The mortality among depressed people was significantly higher than that in the control group. The results of our study give reason to believe that home-care staff are in a key position to identify depressed subjects. They have to understand the relationship between depression and the effect of various diseases on health and functional capacity. It is also important to ensure efficient communication between those responsible for health care.

How relatives adjust after the death of a patient with cancer in hospice

This study aims to discover (1) how relatives adjust to their new life situations following the death of a patient with cancer in hospice and (2) how those relatives have been supported by healthcare professionals both before and after the patient's death. The data were collected with a structured questionnaire administered to relatives of patients with cancer who died in a Finnish hospice in 1998 and 1999. The questionnaires were administered by the hospice staff to all family members who met the criteria specified (n = 589). The final sample comprised 258 family members, most of whom were the deceased patients' spouses. The Mann-Whitney U-test and the Kruskal-Wallis test were used to analyze the data. Instrument reliability was ascertained by the Cronbach alpha coefficient. The relatives had little difficulty accepting their new life situation and adjusting to their new role. The main factors affecting adjustment were being the patient's spouse and the age of both patient and relative. Relatives believed that they received a moderate amount of support from healthcare professionals, both before and after the patient's death. Most of the information they received concerned the patient's illness and treatment and daily condition. Communication was honest and based upon the relatives' needs. Emotional support before the patient's death consisted mainly of accepting the relative and listening to what relatives had to say.

Security associated with pregnancy and childbirth--experiences of pregnant women

The aim of this study was to describe security associated with pregnancy and childbirth. Security was described as a human need and as human value. Data were collected in semi-structured interviews in two maternity health care clinics. Data interpretation was based on the method of content analysis. A convenience sample of 20 volunteer Finnish women was interviewed during pregnancy. The elements creating security associated with pregnancy and childbirth were maternity health care, social support, sense of control, and attitudes. The feeling of security was manifested in different resources, feelings and behavior. If the feeling of security associated with pregnancy and childbirth was impaired, the participants would resort to their network of social support, contact health care or social welfare services, or try to achieve a sense of security by their own resources. Feeling secure during pregnancy influences the pregnant woman's resources, feelings and behavior. It is important that professionals in maternity health care talk with the client about issues that influence her individually-experienced security associated with pregnancy and childbirth. These include examination of the client's network of social support and informing the client about the health care and social welfare services available.

Attitudes of patients with breast and prostate cancer toward complementary therapies in Finland

This study aimed to describe the attitudes of patients with breast cancer and those with prostate cancer toward complementary therapies. The data were collected with a postal questionnaire administered to 216 patients with breast cancer (response rate, 55.4%) and 1 90 patients with prostate cancer (response rate, 54.9%) in southern and southwestern Finland. The questionnaire was composed of 44 Likert-type statements, which were analyzed using descriptive statistics, chi2 tests, t tests, and two-way analyses of variance. More than half (54%) of the patients with breast cancer and 45% of the patients with prostate cancer believed that people with cancer may benefit from complementary therapies, although they did not think these therapies actually could cure cancer. More than half of the respondents were dubious about using complementary therapies as long as there was no solid scientific evidence. Most believed that complementary therapies were used because they gave people hope (women, 88%; men, 72%) or "something to cling to" (women, 83%; men, 76%). The respondents believed most in dietary therapies and least in healing. There was much confusion and uncertainty about the professional competencies and expertise of the people who provided complementary therapies. Approximately one fourth of the respondents had spoken to their physician about complementary therapies. Only a few had talked about the matter with nursing staff. About half of the respondents thought that physicians and nurses took a negative attitude toward complementary therapies. In both groups, patients who had talked with their physician about complementary therapies tended to show a more positive attitude.

Patient participation in decision making about care

The purpose of this study was to find out how cancer patients perceive patient participation in decision-making and to see which factors in their view facilitate and restrict participation. Data were collected in focus group interviews with 25 patients, most of whom had breast cancer. Data interpretation was based on the method of qualitative content analysis. The results showed that patients, nurses and physicians all play a part in terms of how patients participate in decision-making. Patients defined participation in decision-making in terms of asking questions, obtaining/providing information and choosing from/presenting different alternatives. Among the factors that were thought to promote participation in decision-making were the patient's activity, the presence of a primary nurse/physician, the encouragement of nurses and physicians to participate, the treatment of patients as equals, and nurses and physicians having enough time for patients. As for factors hindering participation in decision-making, reference was made to patient ignorance, physical and mental imbalance and shyness on the part of the patient. Obstacles to participating in decision-making that originated in the nurses and physicians were the tendency for them to treat patients as objects, to fall in a routine, problems with information dissemination and lack of time.

An exploratory study of clinical decision-making in five countries

PURPOSE

To identify the cognitive processes nurses use in their decision-making in long- and short-term care settings in five countries, and the demographic variables associated with their decision-making. METHOD AND SAMPLES: The instrument used was a 56-item questionnaire that has been shown to be reliable in earlier studies. The sample consisted of five convenience samples of registered nurses working in either geriatric wards (n = 236) or acute medical-surgical wards (n = 223) in hospitals or nursing homes in Canada, Finland, Sweden, Switzerland, and the United States.

FINDINGS

Five models of decision-making were identified on the basis of factor analysis. They represent both analytical and intuitive cognitive processes. Analytical cognitive processes were emphasized in information collection, problem definition, and planning of care, and intuitive cognitive processes were emphasized in planning, implementing, and evaluating care. Professional education, practical experience, field of practice, and type of knowledge were significantly associated with decision-making models as well as with country of residence of the participants. The highest proportion of analytically oriented decision-makers was found among nurses in long-term care, the decision-making of nurses in short-term care was more intuitively oriented.

CONCLUSIONS

The results indicate that decision-making of participants varied from country to country and in different nursing situations. Future research should be focused on reasons for these differences, the relationship between the task and the nurses' type of knowledge, and how nurses use their knowledge to make decisions in different nursing situations.

Giving birth. Perceptions of Finnish childbearing women

PURPOSE

To describe the lived experience of childbirth with women giving birth in Finland.

DESIGN

Phenomenology.

METHODS

Twenty Finnish women who had recently given birth were interviewed within 2 weeks following childbirth, sharing their perceptions of meaning of their childbirth experiences. Culturally appropriate strategies for qualitative data collection were employed. Trustworthiness of the data was ensured.

RESULTS

The richness and diversity of the childbirth experience emerged from the data. One theme identified was a sense of awe at the creation of a new life within the context of birth as a bittersweet paradox. A strong sense of maternal confidence or self-efficacy was identified, which influenced the women's perception of and management of childbirth pain. Feelings of self-actualization were articulated as Finnish women successfully negotiated a challenging life event.

CLINICAL IMPLICATIONS

Perinatal nurses should increase their sensitivity to the socio-cultural context of giving birth by acknowledging women's experiences as legitimate sources of knowledge.

Nursing students' knowledge of and views about children in pain

It is important to evaluate the outcomes of the given education to gain knowledge about the abilities of our students to meet the needs of nursing practice. Pain associated with different illnesses and procedures is one of the most common symptoms that children experience in the hospital. The purpose of this study was to evaluate the views and knowledge base of graduating nursing students in the area of taking care of children in pain. The data were collected with a purpose-designed Likert-type instrument from all nursing students that graduated during one year from the child nurse specializing program in Finland (n = 85), with a response rate of 86%. Results indicate that students have mainly positive views and attitudes towards taking care of children in pain. The views and attitudes differ when older and younger students and students from different schools are compared. Students lack knowledge especially in the area of pain medications as well as in the assessment of pain. In the knowledge section, the results did not differ greatly when different schools, younger and older students or previous working experience and no working experience were compared. In some of the researched schools, many of the students felt a lack of confidence about their knowledge. There is a need for more detailed education in the area of taking care of children with pain.

Self-care in adults with asthma: how they cope

The purpose of this study was to find out how well adult asthma patients in Finland cope with self-care in three areas of asthma treatment. The areas of physical, psychological and social asthma treatment were examined. Associations between demographic background data and self-care were also studied. Data (n = 130) for the study were collected using a questionnaire specially developed for this study. A deductive perspective was employed in data analysis. Respondents showed fairly good competence in self-care in all three areas of asthma treatment. However, up to 30% of the asthma patients had pets and 16% were smokers. Extra stress was reduced by exercise and positive thinking. Humour was also important in helping most of the respondents cope mentally. Social support played a significant part in fighting the sense of powerlessness which is caused by asthma. According to the results, women coped better than men in the social area of self-care.

Participation of relatives in the care of cancer patients

This study aims to find out how important it is for relatives to take part in the care of cancer patients and to see to what extent they actually do take part. Participation is defined as consisting of concrete care activities, emotional support and participation in decision-making concerning the patient's care. The sample comprised 168 relatives of cancer patients from oncology wards all over Finland. Data were collected with a questionnaire specifically developed for this study. Nonparametric tests were used for statistical analyses. The results showed that the most important aspect of relatives' participation was supporting the patient emotionally; providing concrete care and participation in decision-making were both considered less important. Over 80% of the relatives said they gave a considerable amount of support to the patient. Most relatives said that they visited the patient in hospital, talked to the patient about their concerns and were near them whenever they felt they needed that. On the other hand, relatives did not take part in discussions about care, nor were they informed about such a possibility.

A description of birth in Finland

The health care of women and children living in Finland is described. In the Finnish health care delivery system, perinatal health care is family centered, maximizing professional support through use of nurses in the delivery of primary care across the childbearing year and technological interventions are judiciously used based on evidence of efficacy.

Informational and emotional support for cancer patients' relatives

The purpose of this study was to find out what cancer patients' relatives think about the actions of health care professionals in terms of providing informational and emotional support. The sample consisted of 168 relatives of patients from oncological wards all over Finland. The data were collected with a questionnaire specifically developed for this study. Non-parametric tests were used for statistical analysis. The results clearly highlighted the importance of informing relatives about the patient's illness. However, less than one-third of the relatives said they received much information. Relatives' need for emotional support was clearly at a lower level than their need for information. Even so, only very little support was provided in relation to relatives' needs.

Patients' and nurses' assessment of cancer pain

The purpose of this study was to examine hospitalised cancer patients' and nurses' assessment of patients' cancer pain and to compare them. The data were collected from 51 patient-nurse pairs in two hospitals from oncological and medical clinics. Each nurse and patient took part in the study no more than once. The data were collected with a structured interview and the questionnaire. The intensity of pain was measured with a visual analogue scale (VAS) and the Finnish version of the McGill Pain Questionnaire (FPQ). The results showed that the differences between patients' and nurses' assessments were statistically significant for most intensive pain and for acceptable pain. In both cases nurses' assessments of the intensity of pain were lower than patients' assessments. The nurses identified 40 words in the verbal FPQ that the patients used in describing their experiences of pain. The words used most often by patients were agonizing, tender, wave-like and radiant. The word that the nurses used most often was that of intense. Nurses' knowledge about pain medication in general and morphine in particular was clearly associated with the differences observed in estimates of the intensity of pain. Nurses with poor knowledge underestimated the patients' most intensive experiences of pain. The difference was statistically significant.

Nursing activities and outcomes of care in the assessment, management, and documentation of children's pain

This study describes how assessment and documentation of children's acute postoperative pain is managed by nurses in university hospitals in Finland. A survey was conducted of 303 nurses working in children's wards of university-affiliated hospitals, and at the same time a retrospective chart review of 50 consecutive cases of operation of acute appendicitis was carried out. Charts were analyzed by content analysis, and the results of the survey are reported with percentage distribution and nonparametric statistical calculations. The results indicate that nurses assess pain mainly by observing the child's behavior and changes in physiology. Pain measurement instruments are rarely used, and nurses do not recognize them. The documentation of pain care is unsystematic and does not support the continuity of care. There is a clear need for development of assessment and documentation practices in the studied hospitals. Future research should look at the postoperative care of pain at home as well as care in non-university-affiliated hospitals.

What asthma patients know about their illness and its treatment

The purpose of this paper is to describe what adult asthma patients in Finland know about asthma and its treatment. The data were collected with a questionnaire specifically developed for this study. The response rate was 86.6% (n = 130). The respondents' knowledge scores were quite high: 34% had good knowledge, 51% had fairly good knowledge, and 15% had satisfactory knowledge of their disease and its treatment. Women knew more about asthma and its treatment than men (p = 0.043). The item on which there was most uncertainty related to whether it is possible to prevent asthma. The most surprising finding was that as many as 30% believed that the only way to reduce asthma symptoms is by effective medication.

Nurses' knowledge about pharmacological and nonpharmacological pain management in children

The purpose of this study was to investigate the knowledge base and practices of Finnish nurses in the area of children in pain. The convenience sample consisted of 265 nurses working on children's wards in university hospitals. Data were collected using an instrument designed for the study. The results showed that there remain gaps in the knowledge base of nurses with regard to both pharmacological and nonpharmacological pain management in children. The education and the area of expertise were significant influences on knowledge scores. Nurses used a fairly wide range of nonpharmacological pain alleviation methods but most of these were such that the nurse was in an active role and the child was passive. There is a clear need for further education. Nurses should take a more active role in seeking new information and also should be encouraged to use nonpharmacological methods that let the children be active participants in their own care.

Decision making of psychiatric nurses in Finland, Northern Ireland, and the United States

The purpose of this study was to describe the decision-making process of 339 psychiatric nurses in Finland, Northern Ireland, and the United States and to discuss any differences observed among nurses in these countries. The instrument used in the study was a 56-item, Likert-type questionnaire tested in several previous studies that have confirmed its validity and reliability. Three different models of decision making were identified on the basis of factor analysis. Overall, it may be concluded that the decision-making process of psychiatric nurses is broadly based, but it varies between countries. Nurses from Northern Ireland used only analytical decision-making models; nurses from Finland made decisions strongly favored analytical decision-making models but also used some intuitive models; and American nurses used intuitive decision-making and analytical-processing models.

Fears associated with pregnancy and childbirth--experiences of women who have recently given birth

OBJECTIVE

To describe fears associated with pregnancy and childbirth and to see whether women who have recently given birth feel that their fears were justified.

DESIGN

A qualitative study. Data were collected by semi-structured interviews. Data interpretation was based on the method of content analysis.

SETTING

The maternity units of two university hospitals in Finland.

PARTICIPANTS

A convenience sample of 20 women, 10 primiparae and 10 multiparae. The interviews were held 2 or 3 days after childbirth.

FINDINGS

The most common fears associated with pregnancy and childbirth were concerned with the baby's well-being, the course of pregnancy, and childbirth. The fears found expression in different kinds of behaviours, emotions and physical sensations. Many of the participants felt that their fears had not been justified, but some maintained that their fears had been justifiable.

KEY CONCLUSIONS AND IMPLICATIONS FOR PRACTICE

There was much inter-individual variation in the fears associated with pregnancy and childbirth. It is important that diagnosis during pregnancy is undertaken sensitively and that midwifery staff remember that pregnant women may have very serious fears associated with pregnancy and childbirth. The participants in this study felt that fears associated with pregnancy and childbirth also had positive meanings. It may not be essential to try to protect women against these fears or to remove them altogether, but to give every pregnant women the opportunity to deal with her own fears and to obtain the help she needs in her situation.

Patient’s and general practitioner’s different views on patient’s depression

Differences between patient's and general practitioner's view on patient's depressive syndromes was investigated in a prospective birth cohort study of 70 year old people (n=1032) in Turku City, Finland. The aim of this study was to find factors which are typical for people having depressive syndromes in old age and help medical and nursing staff to identify depressive syndromes in the general aged people. The study consisted of a structural postal questionnaire including patient's perception of his depression, an interview made by a public health nurse included mini-mental state examination (MMSE) and the self-rating depression scale of Zung, an interview and comprehensive clinical examination by a general practitioner. Out of the 847 persons who completed the depression test, 12.6% showed symptoms of depressive syndrome. The views of those who scored more than 45 points in the Zung depression scale on their own depressiveness differed from the general practitioner's opinion. In the general practitioner's examination and interview 58% of the subjects had no depressive symptoms even though the test results indicated that they were depressed. The depressed group stood out most clearly in two questions: Do you feel you are needed and do you have future plans? When the same questions were repeated 5 years later, the difference was still statistically significant between depressed and non-depressed group (P<0.0001). The data indicated that medical and nursing staff should take self-assessments seriously and look into them in closer detail. General practitioners and nurses should learn to ask right questions and use short depression scale systematically in order to facilitate the detection of depressive syndromes.

Oncology nurses' attitudes towards alternative medicine

Little is known about nurses' attitudes towards alternative medicine. The purpose of this study was to describe attitudes towards alternative medicine among nurses working on oncology wards in three university and one central hospital in Finland. The data were collected with a questionnaire specifically developed for this project. The response rate was 68.1% (n = 92). The nurses did not regard alternative medicine as a safe and natural method in the treatment of cancer. On the contrary, many nurses believed that alternative therapies are offered by quack doctors for financial gain. However, the nurses considered it important that cancer patients have the opportunity to talk about their use of alternative medicine both with nurses and physicians. Overall the results indicated that nurses' attitudes are for the most part negative. An interesting question that deserves further attention is whether this attitude is reflected in nursing practice.

Decision-making models in different fields of nursing

The purpose of this study was to identify the decision-making models used by nurses in different fields of nursing and to find out which variables explain the use of those models. The instrument for the project was developed on the basis of existing decision-making theories and earlier studies on nurses' decision making. The sample consisted of 483 Finnish nurses from five fields of nursing: long-term care, short-term medical-surgical care, critical care, health care, and psychiatric care. The statistical analyses consisted of factor analysis, factor scores, and correspondence analysis. Five different models of nursing decision making were identified. The nature of the nursing task and the nursing context showed associations with decision making on all models. The structure of knowledge and nurses' practical experience did not provide an explanation for nurses' decision making on any model.

Cancer patients' reported experiences of suffering

This study describes the nature and content of experiences of suffering by patients with incurable cancer. The main body of data was collected in interviews. A structured questionnaire was administered for additional information. Three different dimensions were identified in patient experiences of suffering: physical, psychologic, and social. Suffering has a physical foundation, which was divided into two categories: that caused by the illness itself and that caused by treatment of the illness. The primary sources of physical suffering were fatigue, pain, and the side effects of chemotherapy. The causes of psychologic suffering lie in the physiologic changes associated with the disease and in the imminence of death. Psychologic suffering was most typically manifested in depression, which most of the patients suffered during the initial stages of the disease, when the disease metastasized, and when they were in a particularly poor condition. General deterioration and fear of infections very much restrict the social life of cancer patients, causing them to withdraw into their home or the hospital.

Developing the nursing care of breast cancer patients: an action research approach

This study set out to develop the nursing care of breast cancer patients at the Central University Hospital in Turku, Finland, using the methods of action research and to evaluate the results of the development effort from the point of view of both patients and nursing staff. A theoretical model of the care of cancer patients was constructed on the basis of existing knowledge of how people react in stress and crisis situations or at different stages of a difficult illness. A specific care programme for breast cancer patients was also planned for the hospital's oncology and surgical units. Data were collected using questionnaires. Results indicated that our theoretical model of the care of cancer patients worked reasonably well. They also clearly highlighted the areas in which there is room for further improvement. Patients' experiences of the nursing staff were generally positive and the majority of the nursing staff also regarded the development project as a success.

Ethical dilemmas in the care of patients with incurable cancer

This article aims to identify and describe the ethical dilemmas that are involved in the care of patients with incurable cancer. The data were collected in semistructured focused interviews with 32 patients, 13 nurses and 13 doctors from two central hospitals and four community health centres. The interviews were tape-recorded and transcribed verbatim. Interpretation was based on the method of content analysis. Ethical dilemmas occurred at the time of diagnosis, in connection with telling the truth, in providing information, in the treatment of pain, and in decision-making situations concerning active treatment. Dilemmas of active treatment concerned chemotherapy, intravenous infusions, blood transfusions and antibiotics. There were also problems in relationships between nursing staff and next of kin, as well as a lack of co-operation between nurses and doctors.

Decision making of nurses practicing in intensive care in Canada, Finland, Northern Ireland, Switzerland, and the United States

In this study, our intention was to describe the decision making of nurses practicing in intensive care, and the differences of nurses' decision making in Canada, Finland, Northern Ireland, Switzerland, and the United States. The instrument used in the study was a 56-item Likert-type questionnaire that has been used in previous studies and has proved to be a reliable tool. The target group comprised a nonrandom sample of nurses (N = 314) from five countries. The samples are not representative; therefore, the results in these cases cannot be generalized. The results showed that the decision making of nurses practicing in intensive care was broadly based, and that there were some country differences in data collection, problem definition, and planning. In contrast, decision making related to the implementation and evaluation of nursing is quite similar in the different countries. Canada and the United States on the one hand, and Finland, Northern Ireland, and Switzerland on the other, showed more similarities with each other in data collection, problem definition, and nursing planning related to decision making. Neither experience nor nurse's knowledge structure was associated with different decision-making approaches.

The beta 1,6-GlcNAc transferase activity present in hog gastric mucosal microsomes catalyses site-specific branch formation on a long polylactosamine backbone

We find that the beta 1,6-GlcNAc transferase activity present in hog gastric mucosal microsomes converts the linear pentasaccharide GlcNAc beta 1-3Gal beta 1-4GlcNAc beta 1-3Gal beta 1-4GlcNAc (1) in a site-specific way to the branch-bearing hexasaccharide GlcNAc beta 1-3(GlcNAc beta 1-6)Gal beta 1-4GlcNAc beta 1-3Gal beta 1-4GlcNAc (2). The product is a positional isomer of GlcNAc beta 1-3Gal beta 1-4GlcNAc beta 1-3(GlcNAc beta 1-6)Gal beta 1-4GlcNAc (3), reportedly formed from 1 by another polylactosamine beta 1,6-GlcNAc transferase activity present in human serum (Leppänen et al., Biochemistry, 30 (1991) 9287). Combined use of the two kinds of activities gave in the present experiments the heptasaccharide GlcNAc beta 1-3(GlcNAc beta 1-6)Gal beta 1-4GlcNAc beta 1-3(GlcNAc beta 1-6)Gal beta 1-4GlcNAc (4), in which one of the branches occupies the position of the branch in 2 and the other the position of the branch in 3.

Public health nurses' decision making in Canada, Finland, Norway, and the United States

The purpose of this study was to describe the decision-making processes of 369 public health nurses in Canada, Finland, Norway, and the United States, and to discuss any differences observed among these countries. The results indicate that public health nurses used different decision-making models on the job and that these models varied considerably. Five different decision-making models were identified, each exhibiting features of different decision-making theories. The differences between decision making of public health nurses in different countries were statistically significant. The differences in decision making appear to be due to differences in health care systems in the 4 countries and the nature of the nursing task and context.

Patients' needs in hospital: nurses' and patients' views

This study set out to identify the most important needs of hospital patients on surgical and medical wards and to assess the ability of nurses to identify these needs. The population consisted of 92 Finnish patients and 69 Finnish nurses. The study was carried out using a questionnaire designed on the basis of the need theory presented by Yura and Walsh. The results of the statistical analyses were presented in the form of frequencies, cross-tabulations and chi-square tests. The patients' most common needs were related to vital functions (44%), followed by those related to functional health status (38%) and environmental needs (36%). The last item on the list of expressed needs concerned reactions to functional health status (31%). Over 70% of the surgical patients suffered from problems related to sleep and rest. Less than 60% of them suffered from acute pain. Medical patients, in turn, had more frequent needs related to vital functions than did surgical patients. Three out of four medical patients suffered from acute pain. Sleep and rest disturbances, stress, bad mood and listlessness were also common problems. The nurses underestimated all patient needs, apart from environmental needs, which they regarded as the main concern of patients. There was a statistically significant difference between patients' and nurses' assessments for 38% of all needs. Moreover, there were differences in assessments between the surgical and medical wards included in the study.

Developing an instrument for the observation of touching

This article describes the development of an instrument for the observation of nonnecessary touching and its purposes in interaction between nursing staff and elderly patients in long-term care. The work took place on three wards of a nursing home. The instrument is based on three main concepts: verbal communication, touch as a form of nonverbal communication, and nursing care situation. In its finalized form, the instrument consists of a single sheet of paper with the human body pictured from the front and from the back.

Cultural perceptions of childbirth: a cross-cultural comparison of childbearing women

The purpose of this comparative cross-cultural study was to describe the cultural/religious perception of the childbirth experiences of selected childbearing women. Finnish Lutheran women's beliefs and perceptions of childbirth were compared with those of Canadian Orthodox Jewish and American Mormon women. Methodological triangulation was achieved through semistructured, open-ended interviews and use of the Utah Test for the childbearing Year (UTCY). Canadian Orthodox Jewish women showed a significantly higher level of reliance on authority figures to ensure positive outcomes and significantly less active participation in childbirth care decisions. The Finnish Lutheran women showed less valuing of childbearing and childrearing, which may be related to a less active religious belief system and the view by Finnish women that motherhood is only one of a multiplicity of roles viewed as important. There is a need to understand and appreciate the cultural beliefs and values of childbearing women to facilitate more culturally sensitive and holistic nursing care.

Decision-making models of Finnish nurses and public health nurses

This study described nursing decision-making models and variables related to these models. For this purpose a 56-item Likert-type questionnaire was constructed according to the Dreyfus model of skill acquisition as applied to nursing by Benner and information processing theory. The target group consisted of 100 registered nurses working in inpatient clinics and 100 public health nurses working in preventive health care. The decision-making variables explored were nurses' experience, education and knowledge as well as the nature of the nursing task and context. The results revealed four different types of decision-making: (a) unquestioning/questioning decision-making, (b) creative-diversive decision-making, (c) patient/nurse-oriented decision-making, and (d) rule- and situation-based decision-making. The most important factors related to decision-making were experience and the nature of the nursing task and context.

Ethical reasoning concerning the feeding of severely demented patients: an international perspective

Structured interviews were held with 149 registered nurses in seven countries in America, Asia, Australia and Europe concerning the feeding of severely demented patients who do not accept food. The most common reasons for nurses being willing to change their decision to feed or not to feed were an order from the medical head, a request from the patient's husband and/or the staff meeting. There was a connection between the willingness to feed and the ranking of ethical principles. Nurses who were most prone to feed the patient most often gave a high rank to the ethical principle of sanctity of life, while those who primarily chose not to feed the patient gave a high rank to the ethical principle of autonomy. All nurses stressed the ethical principle of beneficence.
