Initiation and direction of polymorphonuclear leucocyte locomotion. The particle collision hypothesis.

A simple model of the initiation of locomotion, the random movement and the directional locomotion during chemotaxis is derived from observations on moving human polymorphonuclear leucocytes (PMNs). This model provides a unifying concept of initiation of PMN locomotion, PMN random movement and PMN chemotaxis. The lamellipodium is thought to be the direction-determining cell organelle.

The meaning of hospital care, as narrated by elderly patients with chronic heart failure.

Chronic heart failure is the most common reason for hospitalization among the elderly in western societies. To elucidate the meaning of the experience of care received in the hospital, as narrated by 12 elderly patients with severe chronic heart failure, interviews were analyzed by an approach inspired by Ricoeur's phenomenologic hermeneutics. The analysis revealed that the study respondents experienced the care as "unpredictable." This essential theme captured the divergent descriptions of 2 subthemes: care was either "confident but incomprehensible" or "nonconfident and incomprehensible." When the patients sought care, it was as though they were launching themselves into the unknown because they knew that many experiences would be unpredictable. Despite experiences of indifferent and unpredictable care, the narratives revealed a need to rely on the caregivers' expertise.

Narratives of care providers concerning picking behavior among institutionalized dementia sufferers.

To illuminate the meaning of picking behavior in institutionalized people with dementia, the narratives of 15 care providers were interpreted using a method inspired by Ricoeur's phenomenologic hermeneutics. The care providers saw the behavior as a form of meaningful communication. The behavior was described as occurring in combination with wandering and in connection with restlessness and stress related to fatigue, difficulty communicating, and lack of occupation. The behavior also was seen as an attempt to engage in meaningful activities. Some care providers reported that the picking behavior caused them strain, whereas others reported a more positive reaction because the behavior made the ward more alive. Most care providers perceived the meaning of the picking behavior relative to the dementia sufferer's previous life and said they reacted by diverting, allowing, or understanding the picking.

Skilled nurses' experiences of caring.

The content and the meaning of nurses' caring in practice remain poorly illuminated. To contribute to a better understanding, the meaning of caring, abilities needed for caring, experiences that make caring worthwhile, and the source of the strength needed to continue caring were focused on in interviews with experienced nurses in surgical (n = 15), medical (n = 15), and long-term (n = 15) care. The analysis showed both similarities and differences between the three groups of nurses. One similarity lay in the ability of the nurses within their caring role to understand the situation, to establish contact with the patient, and to act in the patient's best interest especially regarding the relief of pain and anxiety. On the other hand, one of the differences was that the nurses engaged in long-term care emphasized support of the patients' psychosocial needs more than nurses engaged in surgical and medical care, who emphasized support of the patients' weakened vital functions. The analysis also disclosed that almost all of the nurses had been troubled by problems of patient care when they were new to their jobs, but experience and maturity had given them strength. Care in itself gave the nurses satisfaction and pleasure and made it worthwhile. Positive cooperation with coworkers and patients' families were the main sources of their strength to continue caring.

'Overshoot' of ethanol in the blood after drinking on an empty stomach.

The time required for ethanol to distribute between the systemic circulation and the rest of the body water results in an 'overshoot' of the blood-alcohol concentration (BAC) during the first 30 min after intravenous infusion. To investigate whether a similar distribution phenomenon occurs when ethanol is given by the oral route, we compared BACs after intravenous infusion and oral intake under strictly controlled conditions by giving a 0.4 g/kg dose of ethanol over 15 min to six fasting female volunteers. The results show an 'overshoot' in three volunteers who had the shortest time to BACmax, which indicates rapid absorption, and the time-course was similar to the distribution phase seen during the intravenous experiments. We conclude that BAC is sometimes higher than expected shortly after alcohol has been ingested rapidly. This finding can probably be explained by the fact that ethanol is distributed more slowly throughout the total body water than it is absorbed from the gut.

Striving for becoming at-home in the midst of dying.

Research interviews with 12 patients at an inpatient, free-standing hospice in Sweden were analyzed, using a phenomenological hermeneutic approach, to show the effects of individual nursing care as experienced by the guests. The findings revealed that the effects of, and reactions to, nursing care were inseparable from the hospice milieu and the patients' situation, which was interpreted as including the prospect of becoming homeless. Thus, the effects of hospice spirit (nursing care and milieu) as experienced by these hospice patients represented the contrasting possibilities of hindering--or contributing to--the prospect of becoming homeless. What the patients spoke about was either a consoling or a desolating hospice spirit. A consoling hospice spirit supports experiences of wholeness and communion, i.e., becoming at-home in the midst of dying, while a desolating hospice spirit results in feelings of alienation and fragmentation, i.e., feeling homeless. Considering the dying person to be a guest rather than a patient is an important component of Swedish hospice philosophy and supports the view of the dying person as an autonomous and dignified human being.

Men's experiences during the acute phase of their partners' myocardial infarction.

The men's narratives about the women reveal a disturbance in the balance of their daily life, showing how they, the men, perceive powerlessness, and also how they passively adapted themselves to what happened. The narratives reveal that the women are 'ignoring and withholding' their feelings and that they want to be as 'responsible and independent' as they used to be. The women are disclosed as 'not wanting to face reality': there is an enervating lack of communication.

Being the parent of a child with asthma.

The aim of this study is to describe what it means to be parents of a child with asthma. Unstructured interviews were carried out with 12 mothers and 12 fathers of children with asthma living in Sweden. The parents' accounts were analyzed using a phenomenological-hermeneutic approach. The results revealed that parents were living a strenuous life and their actions involved both protecting and liberating. Parents also reported feelings of sadness and acceptance. In most cases, mothers acted in a protecting manner and expressed feelings of sadness; fathers acted in a liberating manner and expressed feelings of acceptance. To gain a deeper understanding of the parents' actions and feelings, study results were interpreted through philosophical perspectives described by Ruddick (1989), Mayeroff (1965), and Hegel (1975). These interpretations show that the feelings and actions of these parents exist in a dialectical relation with one another. Results emphasize the importance of a good partnership between the parents and the nurse, where the nurse shows consideration for the parents' unique actions and feelings and understands and supports parents in the care of their child with asthma.
