- The aim of this study was to enrich the understanding of patients' perspective of being diagnosed and treated for ovarian cancer. A qualitative approach was used to obtain knowledge and insight into patients' experiences and thoughts. Ten Swedish women, diagnosed with ovarian cancer, participated in a total of 23 interviews on 3 occasions: at the time of diagnosis, during chemotherapy, and after completion of chemotherapy. The results of the interpretation of the interviews were formulated in the form of 3 themes: (1) feeling the same despite radical castrating surgery, (2) accepting chemotherapy, and (3) maintaining normality and support. Suggestions of caring implications from our interpretation of the interview data underscore the need to support these women in learning to cope with their feelings of weakness and anxiety. The findings further indicate the potential in narrative methods to identify important issues in comprehensive cancer care.

- BACKGROUND: In chronic heart failure (CHF) it has been proposed that a dysfunction of the gastrointestinal barrier could lead to translocation of endotoxin into the systemic circulation. A secondary inflammatory reaction, observed as increased levels of cytokines, could negatively affect cardiac function. The aims of this paper were therefore to determine whether patients with CHF have a disturbed mucosal barrier and whether it was possible to detect endotoxin in venous blood. METHODS: Nineteen stable patients with CHF (New York Heart Association II-III, EF40% and earlier hospitalisation for heart failure) were investigated. Twenty healthy subjects (HS group) and 25 patients, who were admitted for bone marrow transplantation (BMT group), served as controls. Gastrointestinal permeability was assessed by a (51)Cr-EDTA absorption test. RESULTS: Eleven patients with and eight without peripheral oedema were included. Median age was 76.5 years. Intestinal permeability was 1.82+/-1.96% in the CHF patients and 1.54+/-.59% and 1.9+/-.9% in HS and BMT groups, respectively (p=0.4 and p=0.7, CHF vs HS and BMT, respectively). No difference was found between patients with and without oedema and endotoxins were below the detection limit in all patients. DISCUSSION: This study does not support the hypothesis that patients with CHF have a dysfunctional gastrointestinal barrier, at least as assessed by the (51)Cr-EDTA resorbtion test.

- BACKGROUND: The contemporary impact of heart failure (HF) versus the most common forms of cancer as reflected by related first-ever hospitalizations and subsequent case-fatality rates is unknown. METHODS AND RESULTS: Using a national registry in Sweden, we compared the rate of first-ever hospitalization and associated short- and long-term survival for HF, acute myocardial infarction (AMI), and the most common forms of cancer on an age and sex-specific basis during 1988 to 2004 in 949 733 Swedish patients (1 162 309 hospital admissions in total). Annual incidence of first-ever hospitalization for HF, AMI, and cancer in Sweden were 484, 424, and 373 (lung, colorectal, prostate, and bladder cancer combined) per 100 000 men and 470, 280, and 350 (lung, colorectal, bladder, breast, and ovarian cancer combined) per 100 000 women age >20 years. The ratio of individual cases of HF to cancer was 1.37:1 (465 998 versus 340 738). Despite improvements in 30-day and 5-year survival (adjusted 7% and 6% increase per calendar year for men and women, respectively), HF was associated with unadjusted case-fatality rate of 59% within 5 years and 196 400 deaths versus 58% and 131 000 deaths in patients with cancer. During 10-year follow-up, HF was associated with 66 318 versus 55 364 premature life-years lost than all common forms of cancer in men. In women, the equivalent figures were 59 535 versus 64 533 premature life-years lost. CONCLUSIONS: These data confirm that, like most common forms of cancer combined, HF exerts a major health burden in respect to age-adjusted rates of first hospitalization, poor overall survival, and premature life-years lost.

- Nomenclatural type definitions are one of the most important concepts in biological nomenclature. Being physical objects that can be re-studied by other researchers, types permanently link taxonomy (an artificial agreement to classify biological diversity) with nomenclature (an artificial agreement to name biological diversity). Two proposals to amend the International Code of Nomenclature for algae, fungi, and plants (ICN), allowing DNA sequences alone (of any region and extent) to serve as types of taxon names for voucherless fungi (mainly putative taxa from environmental DNA sequences), have been submitted to be voted on at the 11th International Mycological Congress (Puerto Rico, July 2018). We consider various genetic processes affecting the distribution of alleles among taxa and find that alleles may not consistently and uniquely represent the species within which they are contained. Should the proposals be accepted, the meaning of nomenclatural types would change in a fundamental way from physical objects as sources of data to the data themselves. Such changes are conducive to irreproducible science, the potential typification on artefactual data, and massive creation of names with low information content, ultimately causing nomenclatural instability and unnecessary work for future researchers that would stall future explorations of fungal diversity. We conclude that the acceptance of DNA sequences alone as types of names of taxa, under the terms used in the current proposals, is unnecessary and would not solve the problem of naming putative taxa known only from DNA sequences in a scientifically defensible way. As an alternative, we highlight the use of formulas for naming putative taxa (candidate taxa) that do not require any modification of the ICN.

- Intestinal injury 4-48 hr after cytotoxic therapy (etoposide phosphate, 100 mg/kg body weight [bw], intravenously [i.v.]) was studied in rats using ligated intestinal loops. Chromium-51 ethylenediaminetetraacetic acid ((51)Cr-EDTA) and rubidium-86 chloride ((86)RbCl) were deposited intraluminally to determine the extent of the increase in intestinal permeability and ion channel disruption. Evans Blue (EB) was used for detection of endothelial leakage. Intestinal morphology was documented. Endothelial dysfunction, as observed by an increased extravasation of EB, was evident already 4 hr after cytotoxic therapy. Intestinal epithelial injury, as observed by an increase in (51)Cr-EDTA permeation and a decrease in (86)Rb absorption, occurred after 48 hr. Finally, histology disclosed a reduced crypt cell proliferation, displayed as a decrease in Ki67-positive cells. The findings suggest that, in the development of intestinal injury after cytotoxic therapy, endothelial disruption is an early event, whereafter epithelial dysfunction and crypt stem cell arrest occur. This knowledge could be of importance in the design of future intervention trials.

Aggressive B-cell Lymphomas : Studies of Treatment, FDG-PET Evaluation and Prognostic Factors
- 2009

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- To improve outcome in young, high-risk lymphoma patients, treatment was intensified, adding etoposide and rituximab to standard CHOP treatment. Granulocyte-colony stimulating factor (G-CSF) enabled treatment bi-weekly. Results were promising: overall (OS) and event-free survival (EFS) 79% and 60% respectively, median follow up 27 months. Single infusion Ara-C, contrary to expectations, did not prevent relapse in CNS. DLBCL were classified as germinal center (GC) or non-GC derived, using immunohistochemical markers, CD10, BCL6 and MUM1. We investigated the outcome for both phenotypes after adding rituximab to chemotherapy. For 106 patients treated with CHOP alone, the GC phenotype displayed significantly better OS and EFS. In contrast, GC phenotype did not predict outcome in 95 patients treated with immunochemotherapy . Thus, addition of rituximab seems to eliminate the prognostic value of immunohistochemically defined GC phenotypes in DLBCL. To improve evaluation and find non-responders, mid-treatment FDG-PET CT was incorporated into clinical routine for patients with high-risk aggressive lymphoma. For those with positive PET, biopsy followed by treatment intensification was recommended. Twenty-five patients were examined, five with positive PET. Two of these had lymphoma in the biopsy. Two had a negative biopsy, and one had a false positive investigation. Seven patients had increased uptake of uncertain significance. Two patients with uncertain PET, and two with negative PET have relapsed, giving a negative predictive value of 85%. In case of relapse of aggressive lymphoma or if not obtaining CR, high dose chemotherapy with autologous stem cell support (HDT) is standard treatment. HDT outcome for 38 patients with transformed follicular lymphoma was compared to outcome for 79 patients with de novo B-cell lymphoma. At median follow-up of 11.5 years both OS and EFS were superior in the transformed group, OS 67% and 33%, EFS 55% and 27% respectively. Treatment related mortality was less than reported in other studies.

- Fatigue is one of the most prevalent and distressing symptoms of cancer, and is a common side-effect of many of the treatments available for the management of malignant disease. We critically assess the evidence for cancer-related fatigue and its treatment in adults. Little is known about the cause and mechanisms of fatigue, and research into methods of alleviating the condition has focused on treatment for anaemia and behavioural interventions, such as exercise, both of which are effective in reducing fatigue. Although research into the condition has increased considerably in the past decade, important gaps in knowledge remain.

- BACKGROUND: Cancer-related fatigue (CRF) is a subjectively experienced symptom that is multidimensional and multifactorial. Patients with cancer have identified fatigue as one of the major troubling symptoms and the primary cause of distress in their lives. AIMS: The major aim of the study was to examine how patients diagnosed with uterine cancer describe their experience of fatigue, psychological distress, coping resources and quality of life. A secondary aim was to describe the relationship between selected variables. METHOD: A descriptive and correlational design was used and the study was conducted at a university hospital in Sweden. The study population consisted of women, diagnosed with uterine cancer, who where scheduled to receive curative external radiation therapy. Sixty women participated in the study and data were collected through self-report instruments. Demographic and clinical data were extracted from patient records. The data were collected during year 2000-2002. The Conceptual Model of Symptom Management was used as a framework to guide the study. FINDINGS: Patients experienced a low grade of fatigue and psychological distress, but their functional status and global quality of life was high. Significant correlations were found between general fatigue and anxiety and also between general fatigue and depression. There was a significant negative correlation between general fatigue and coping resources. Depression explained 44% of the variance in general fatigue. CONCLUSIONS: The findings provide knowledge about predictors of CRF in women with uterine cancer, and can serve as a basis for future longitudinal studies in which different prophylactic strategies against therapy-related fatigue are prospectively studied.

- PURPOSE/OBJECTIVES: To evaluate how patients diagnosed with uterine cancer experience fatigue, psychological distress, coping resources, and functional status before, during, and after treatment with radiation therapy and to study whether significant correlations exist among these variables. DESIGN: Longitudinal, descriptive, and correlational. SETTING: The Department of Oncology, Sahlgrenska University Hospital, Gothenburg, Sweden. SAMPLE: 60 women diagnosed with uterine cancer who were receiving curative external radiation therapy. Typical participants were 64 years old, married, and on sick leave or retired from work. METHODS: Data were collected through self-report instruments. Demographic and clinical data were extracted from the patients' records. Main Research Variables: Cancer-related fatigue, psychological distress, coping resources, and functional status. FINDINGS: Patients' fatigue scores increased significantly during and after completion of radiotherapy. The participants reported normal levels of anxiety and depression, and their coping resources changed over time. After completing therapy, all dimensions of function had decreased; for social function, the decrease was significant. The correlation over time was significant among fatigue and physical function, role function, and cognitive function. The variation of the change in fatigue after therapy was completed was explained only by the level of fatigue experienced at baseline. CONCLUSIONS: Fatigue is a symptom that increases in connection with radiotherapy. Functional status is influenced by the variation in fatigue levels. Fatigue level before treatment may be an important variable when trying to find a risk factor for the development of fatigue over the course of treatment. IMPLICATIONS FOR NURSING: Nurses must inform patients receiving radiotherapy about the expected changes in fatigue and functional status. Pretreatment screening for fatigue is needed to identify patients at risk for developing fatigue.
