Support for women with breast cancer, and for the district and hospital nurses involved : an intervention study
1995
Doktorsavhandling (övrigt vetenskapligt/konstnärligt) abstract
The purpose of this study was to investigate breast cancer patients’ experiences of their illness and of traditional nursing care (TNC) or supportive nursing care (SNC) respectively, as well as nurses' experiences of support and of caring for cancer patients. An intervention including extended co-operation between the surgical ward and primary health care, shorter waiting times, and changed routines concerning the information about the diagnosis, as well as training and systematic clinical supervision for the nurses, was implemented. Newly diagnosed breast cancer patients (n=47) from two county councils in the south-east of Sweden were interviewed (IV, V). Thirty-four of them completed scales about well-being, burnout, hopelessness, anxiety and depression (VII). The women who had TNC reported lack of professional support during the initial phase of the disease and suggested changes in the care similar to those implemented in the SNC. In the SNC group the women expressed feelings of safety and security after the professional support and the organizational changes in the care. There were significantly more single women and women who had had breast conserving surgery in the SNC group than in the TNC (VII). The hopelessness scores in the SNC group were significantly higher than in the TNC group.Thirty-nine district nurses (DNs) were interviewed at baseline (I), and thirty-three of them completed scales about burnout, empathy, and sense of coherence (SOC) before and after systematic clinical supervision (VI). Twenty-three of the 39 DNs, as well as 9 hospital nurses (HNs) who participated in the clinical supervision, were interviewed about their experiences of this intervention (III). Twenty-nine tape-recorded supervision sessions in three groups of DNs (n=23) were analysed (II). Baseline interviews and analyses of the content of the supervisory sessions strongly emphasized that DNs experienced problems in the home care of seriously ill cancer patients. Deep human contacts were a source of both strain and enrichment. The clinical supervision was said to provide relief from undesirable thoughts and feelings, confirmation of themselves both as individuals and in their professional role, a broader and deeper knowledge and increased self-confidence. There were no significant differences in the burnout, empathy, and SOC scores between the supervisory group (n=21) and a comparison group (n=12) at the first and second measures, nor over time within the groups. There were some correlations between these phenomena and the Karolinska scales of personality, as well as correlations between burnout, empathy and SOC.The groups of women were not entirely similar as regards demographic and medical characteristics, and the sample size of patients and nurses was small. It is obvious that patients in the TNC missed those factors that were implemented in the SNC, at the same time the latter women expressed hopelessness more often than those who had received TNC. This result may be due to the fact that support from nurses had made the women more prepared to express their feelings, that support had not been provided to an adequate extent or in the right way, or that the applied scales were not appropriate. The finding that the nurses experienced the clinical supervision as very positive but that, despite this, there were no significant differences in attitudes measured by scales within or between the groups, can be interpreted in a similar way. Consequently, further research is needed to judge the effects of intervention. The study has, above all, produced qualitative descriptions of patients' experiences of the nursing care after discharge from hospital, and of DNs’ experiences of the care of cancer patients in their homes, and of systematic clinical supervision.

Prostate cancer : epidemiological studies
1995
Doktorsavhandling (övrigt vetenskapligt/konstnärligt) abstract
Prostate cancer is a large and increasing medical problem both in Sweden and in the rest of the developed world, with about 300.000 new cases diagnosed world wide annually. Despite the high incidence of this disease, little is known about the aetiology of prostate cancer. The aim of this study was to try to understand more about the natural history and to find possible a etiological risk factors for this tumour.In a population based study of prostate cancer cases in northern Sweden it was found that the large increase in prostate cancer during the last two decades was mainly caused by well (Gl) and moderately (G2) differentiated tumours. However, the incidence of poorly differentiated (G3) tumours remained unchanged. The introduction of new diagnostic methods is the most plausible explanation for the increase of these low grade tumours.The relative survival in prostate cancer was found to be independent of patient age at diagnosis, indicating that tumour proliferation and the aggressiveness of this disease is equal in all ages. However, due to the increasing occurrence of concurrent diseases with growing age the number of lost years caused by prostate cancer decreases dramatically in older age groups. The overall cause specific mortality for prostate cancer was found to be around 50%. In accordance with most other cancer tumours, the annual mortality rate decreased with longer survival also for prostate cancer patients.In a study from the Swedish Twin Register it was found that the proband concordance rates for prostate cancer were 4,5 time greater among monozygotic compared to dizygotic twins. In a large nation-wide cohort study of men who had a father with prostate cancer, the overall standardised incidence ratio (SIR) was 1.70 for prostate cancer. Younger age at diagnosis among the fathers were associated with an increased risk among sons. This cohort study and the twin study indicates that both inherited and familial factors are of importance in a subgroup of prostate cancer patients.In a prospective case-control study, both a high body mass index (BMI) and a high food intake were found to be independent risk factors for prostate cancer. Both BMI and a high food intake might be indicators of a high fat diet, which so far is the most consistent exogenous risk factor for prostate cancer. The use of tobacco or alcoholic beverages were not associated with prostate cancer risk.

An Inr-containing sequence flanking the TATA box of the human c-sis (PDGF-B) proto-oncogene promoter functions in cis as a co-activator for its intronic enhancer
1995
Ingår i: Oncogene. - 0950-9232 .- 1476-5594. ; 11:9, s. 1873-1884
Tidskriftsartikel (övrigt vetenskapligt/konstnärligt) abstract
High-level activity of the human PDGF-B promoter in choriocarcinoma cell lines depends upon an atypical, intronic enhancer-like element which does not function with heterologous promoters tested. An extensive series of mutant PDGF-B promoter-driven constructs identified a sequence flanking the TATA box which is required specifically for enhancer-mediated transcription in human choriocarcinoma cell lines. This element, which we here term an enhancer-dependent cis co-activator (EDC) contains an Inr (initiator) consensus sequence upstream of the TATA box which is required, but not sufficient for its function. Requirement for the EDC is cell type-specific, since it was dispensable for enhancer-mediated transcription in a human breast cancer cell line. Although it lies within the region defined, the TATA box itself is not required for EDC function, or for basal promoter function which may derive from a second Inr-like sequence situated at the transcriptional start site. These observations indicate that interactions between some promoter and enhancer elements may be more complex than that generally described for 'classical' enhancer systems and may suggest an additional function for the initiator motif.
