Strategies for understanding. A case study of occupational therapists' communication behaviour

This study focuses on the communication strategies of occupational therapists. Many recent studies in occupational therapy emphasize the importance of having a client-oriented perspective; the needs and wishes of the patient should form the basis for treatment. Such a perspective brings to the fore the capacity of the therapist to enter into the life-world of the patient. Communication, dialogue between patient and therapist, is the basic source of such knowledge. In this paper, understanding verbal acts is seen as fundamentally problematic. The purpose is to analyse what strategies and tactics occupational therapists use to create a basis for their interpretation of patients' messages. What kinds of questions and other forms of verbal behaviour are utilized to check and verify these interpretations? A case-study of communication behaviour during five meetings between patients and therapists in the homes of the patients was undertaken. Seven types of tactics were observed and categorized as belonging to two different strategic dimensions: active-passive and abstract-concrete. Although active strategies were predominant, only one therapist consistently used a combination of ‘asking open questions’ and ‘verifying’ interpretations, the two most active tactics. Most therapists also asked the patients to concretely ‘show in action’ what they meant, but to a varying degree. A consistent use of active-concrete strategies is arguably an ideal way of seeking knowledge and understanding. Empirically, therapists differ in how closely they fit this ideal. This may be a result of training and experience, but also of degree of empathy. This study points to the importance of carefully developing communication strategies in order to fully understand the problems of the patients. Copyright © 1997 Whurr Publishers Ltd.     

Structural and functional aspects of platelet-derived growth factor and its role in the pathogenesis of glioblastoma

The platelet-derived growth factor (PDGF) family consists of three different dimeric forms, AA, BB, and AB, of the two consitituent polypeptide chains, A and B. These interact with two different cell surface receptors that, in part, mediate different cellular functions. The various forms of PDGF, as well as the receptors, are expressed at high frequency in glioblastoma multiforme, and it has been suggested that the growth of this tumor might be affected by autocrine loops involving PDGF and its receptors. The present paper focuses on recent discoveries regarding the family of PDGF ligands and receptors, as well as reviews results concerning PDGF-dependent autocrine growth in experimental and spontaneous glioblastoma.     

Induction of apoptosis of human primary osteoclasts treated with extracts from the medicinal plant <Emphasis Type="Italic">Emblica officinalis</Emphasis>

Background  

Osteoclasts (OCs) are involved in rheumatoid arthritis and in several pathologies associated with bone loss. Recent results support the concept that some medicinal plants and derived natural products are of great interest for developing therapeutic strategies against bone disorders, including rheumatoid arthritis and osteoporosis. In this study we determined whether extracts of Emblica officinalis fruits display activity of possible interest for the treatment of rheumatoid arthritis and osteoporosis by activating programmed cell death of human primary osteoclasts.     

Antibodies to DNP, DNP—glycylglycylglycine and DNP—p-aminobenzoylglutamate

The antibodies to a series of three dinitrophenyl (DNP) derivatives of increasing site-filling capacity (DNP; DNP—glycylglycylglycine and DNP—p-aminobenzolylglutamate) have been isolated in order to assess the effect of the molecular dimensions of a haptenic group on the diversity of the immune response. A decrease in both the intensity and first appearance of precipitable antibody associated with an increase in molecular size of the hapten was observed. In a 5-week interval, the affinity constant for the homologous hapten of anti-DNP—BGG antibody increased approximately 100-fold. In the same interval, the affinity of anti-DNP—glycylglycylglycine—BGG antibodies changed only three- to four-fold and no change in the affinity constant was observed for the anti-DNP—p-aminobenzolyglutamate—BGG antibodies. There were no significant differences in the structural heterogeneity of the antibodies to the three haptens as measured by micro-isoelectric focusing. These observations suggest that temporal variations in binding affinity decreases as the site-filling capacity of the antigeneic determinant increases, thereby restricting the number of ways the determinant can orient itself in the combining site. It would appear that variations in antibody affinity are not indicative of antibody structural heterogeneity.     

The rheumatic patient''s early needs and expectations

During the last few years, studies have revealed that the need for psychosocial support and concrete social services are great in the early stages of the treatment of rheumatic diseases. The ability to keep a job, to do household chores, to participate in leisure activities and to maintain social relations is clearly impaired. Anxiety and depression are not unusual and often associated with weak support from relatives, loneliness and disturbed family relations. Nevertheless, the patients report resilience and determination to cope with the impacts of illness. Crisis intervention, vocational guidance and counselling about problems concerning the disease should be available and offered to the patients. As the patients seem to be unaccustomed to talking about their psychosocial problems, an empathetic and information-seeking attitude on the part of the health care staff is essential.     

Acrocentric interconnections and NOR variants in human lymphocytes

Acrocentric interconnections and NOR (nucleolus organizer region) variants are frequently observed in silver-stained metaphase preparations from lymphocytes of phenotypically normal individuals. The types of interconnections and of NOR variants are outlined. It is speculated that the satellite acrocentrics (both normal and variant) are the consequence of breakage and recoiling of these interconnections. Awareness of these two features of the human genome may facilitate understanding of the NOR/nucleolus interaction(s) in such important processes as nucleolus formation and in development and/or diagnosis of disease states (i.e., malignancy).     

Family functioning in school-age children with cystic fibrosis: an observational assessment of family interactions in the mealtime environment

OBJECTIVE: To examine, using direct observation methodology, differences in family functioning at mealtime between families of school-age children with cystic fibrosis (CF) and families of school-age children without a chronic illness. METHOD: Family functioning was rated using the McMaster Mealtime Interaction Coding System (MICS) during a videotaped dinner among 28 families of children with CF and 27 families of non-ill, age-matched peers. Families were rated on overall family functioning and on six dimensions of the MICS: task accomplishment, communication, affect management, interpersonal involvement, behavior control, and role allocation. RESULTS: Ratings for families of a child with CF were significantly lower than they were for comparison families on overall family functioning and on four of the six MICS dimensions: communication, affect management, interpersonal involvement, and behavioral control. Moreover, a significantly greater percentage of families of children with CF were rated in the unhealthy range on overall family functioning and on five of six MICS dimensions. There was no relationship between family functioning and child weight status for children with CF. CONCLUSIONS: The current study suggests that for families of school-age children with CF, the family system is negatively affected during mealtime. Dietary interventions need to address family-centered, as well as child-centered, interventions to help families manage challenges presented during the family meal.
