- 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.

Tidskriftsartikel (refereegranskat)abstract
- 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.

Tidskriftsartikel (refereegranskat)abstract
- 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.

Tidskriftsartikel (refereegranskat)abstract
- 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.

Tidskriftsartikel (refereegranskat)abstract
- Cancer-related fatigue (CRF) is a prevalent and distressing symptom experienced by patients during cancer therapy. One proposed mechanism for the development of fatigue is the increased secretion of proinflammatory cytokines and/or the development of anemia. The major purpose of this pilot study was to investigate the levels of fatigue and cytokines during radiation therapy and determine whether there was a correlation between the two. A secondary purpose was to explore the relationships among hemoglobin values, cytokines, and fatigue. Participants included 15 women diagnosed with uterine cancer, who received curative external radiation therapy. Fatigue was assessed by a self-report instrument (Multidimensional Fatigue Inventory [MFI-20]) and hemoglobin and cytokines (Il-1, Il-6, and TNF-alpha) were measured before, during, and after radiotherapy. The degree of fatigue increased during radiotherapy without a significant change in IL-1, IL-6, or TNF-alpha levels. There was no significant correlation between changes in general fatigue and the changes in IL-1 and TNF-alpha. There was a significant negative correlation between the change in IL-6 and general fatigue. The hemoglobin levels did decrease significantly during radiotherapy, but there was no significant correlation between general fatigue and hemoglobin after 3 weeks of therapy or after the completion of therapy. In conclusion, pelvic radiotherapy in women with uterine cancer is associated with increased fatigue. There were no significant relationships between anemia or cytokine levels and fatigue. The pathogenesis of fatigue during radiation therapy remains to be elucidated.

- This paper reports on how patients with uterine cancer, receiving radiotherapy, experience fatigue, other symptoms and global quality of life. The results showed that fatigue increased significantly during the therapy. Also the other symptoms; loss of appetite, nausea/vomiting and diarrhoea increased significantly and were significantly correlated to general fatigue. Global quality of life decreased significantly during treatment compared to baseline. The variation of the level in general fatigue after completed therapy was only explained by the level of general fatigue experienced at baseline. The result can lead to a better understanding of the severity of symptoms experienced by patients with uterine cancer treated with radiotherapy.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Despite improved treatment results achieved in Hodgkin's disease (HD), only about 70% of patients with advanced stages are cured. The primary aim of this study was to evaluate the outcome of advanced stages (IIB-IVB) of HD in younger patients in an unselected population-based group of patients. The patients were recommended individualized treatment with respect to number of chemotherapy (CT) courses and post-CT radiotherapy (RT) based on pretreatment characteristics and tumour response. Secondly, we investigated if variables of prognostic importance could be detected.PATIENTS AND METHODS: Between 1985-92, 307 patients between 17-59 yr of age (median 36) were diagnosed with HD in stages IIB-IVB in 5/6 health care regions in Sweden. Median follow-up time was 7.8 yr (1.3-13). Retrospectively, laboratory parameters were collected.RESULTS: In total, 267 (87%) patients had a complete response (CR). The overall and disease-free 10-yr survivals in the whole cohort were 76% and 67%, respectively. There was no difference in survival between the groups of patients who received 6 or 8 cycles of CT. Survival was not higher for patients in CR after CT when RT was added. For those in PR after CT, additional RT raised the frequencies of CR. A selected group of pathologically staged patients was successfully treated with a short course (2 cycles) of CT + RT. In univariate analyses survival was affected by age, stage IVB, bone-marrow involvement, B-symptoms, S-LDH, S-Alb and reaching CR or not after 2, 4 and 6 cycles of CT. In a multivariate analysis, age and reaching CR after 6 cycles of CT remained statistically significant.CONCLUSIONS: The lack of difference in survival between the groups of patients who received 6 versus 8 cycles of CT indicates a successful selection of patients for the shorter treatment. Reaching a rapid CR significantly affected outcome. Whether some patients need less CT than the generally recommended 8 courses can properly only be evaluated in a randomised study. Additional RT may play a role in successful outcome, particularly if residual tumours are present, but its precise role can also only be defined in prospectively randomised studies. Reaching CR after CT was the most important variable affecting survival besides age.

Comparison of novel wide-field in vivo corneal confocal microscopy with skin biopsy for assessing peripheral neuropathy in type 2 diabetes

Tidskriftsartikel (refereegranskat)abstract
- Diabetic peripheral neuropathy (DPN) is a serious complication of diabetes, where skin biopsy assessing intraepi-dermal nerve fiber density (IENFD) plays an important diagnostic role. In vivo confocal microscopy (IVCM) of the corneal subbasal nerve plexus has been proposed as a noninvasive diagnostic modality for DPN. Direct compari-sons of skin biopsy and IVCM in controlled cohorts are lacking, as IVCM relies on subjective selection of images depicting only 0.2% of the nerve plexus. We compared these diagnostic modalities in a fixed-age cohort of 41 participants with type 2 diabetes and 36 healthy participants using machine algorithms to create wide-field image mosaics and quantify nerves in an area 37 times the size of prior studies to avoid human bias. In the same partici-pants, and at the same time point, no correlation between IENFD and corneal nerve density was found. Corneal nerve density did not correlate with clinical measures of DPN, including neuropathy symptom and disability scores, nerve conduction studies, or quantitative sensory tests. Our findings indicate that corneal and intraepidermal nerves likely mirror different aspects of nerve degeneration, where only intraepidermal nerves appear to reflect the clinical status of DPN, suggesting that scrutiny is warranted concerning methodologies of studies using corneal nerves to assess DPN.

Tidskriftsartikel (refereegranskat)abstract
- In order to identify patients at risk for developing post-transplant lymphoproliferative disease (PTLD), a sensitive nested RT-PCR method for detection of EBNA1 gene expression in peripheral blood cells was used. EBNA1 expression in peripheral blood samples from 60 organ recipients was analyzed and compared with 24 healthy controls in a retrospective study. Overall, EBNA1-positive samples were detected at least once in 43% of the transplant patients with post-transplant lymphoproliferative disease, in 18% of the other transplant patients and in none of the healthy controls. The odds ratio for EBNA1 expression in patients with post-transplant lymphoproliferative disease was 3.42 (95% CI=1.02-11.54) compared to other transplant recipients. Together with normal EBV Q promoter initiated EBNA1 transcripts, an alternatively spliced form was expressed in peripheral blood cells in the above-mentioned transplant patients. This transcript lacks the U leader exon in the 5'-untranslated region (UTR). We have previously identified and characterized a functional internal ribosome entry site, the EBNA IRES, in the untranslated U leader exon of EBNA1. Transfection experiments with EBNA1 coding plasmids followed by Western blot showed that the EBNA IRES promotes cap-independent translation and increases the EBNA1 protein level. The alternative EBNA1 transcript lacking this function is expressed in the majority of the investigated EBNA1-positive patient samples as well as in some EBV-positive B-cell lines. Alternative splicing in this form gives EBV potential to regulate the translation of EBNA1 by modifying the 5' UTR. These findings indicate a new mechanism for EBNA1 expression in vivo.

- New records, range extensions and nomenclatural innovations for lichens and lichenicolous fungi from Alaska, U.S.A. - Herzogia 25: 177-210. Surveys of lichens and lichenicolous fungi have been taking place in the U.S. state of Alaska for more than 160 years, but until now assessing the full extent of their diversity has been hampered by the lack of a comprehensive and synonymized baseline inventory. In this paper we will begin to redress this by resolving outstanding nomenclatural issues and providing voucher data for a forthcoming catalog of Alaskan lichens, specifically: 1) synonymization,and/or resolution of status of species previously reported from Alaska, with emphasis on Alaskan types; 2) species new to the Alaska lichen biota; and 3) biogeographically significant new records from within Alaska. We report 91 species new to the flora of Alaska, including 65 lichens, three saprophytic calicioid fungi and 23 lichenicolous fungi. Of these, we report thirteen species, Biatora sphaeroidiza, Biatorella conspurcans, Chaenothecopsis arthoniae, Collemopsidium foveolatum, Dactylospora frigida, Halospora discrepans, Lecanora bryopsora, Opegrapha geographicola, Peltigera lyngei, Petractis clausa, Protoblastenia cyclospora, Thelocarpon impressellum and Usnea cylindrica as new to North America. In addition, Arthonia pruinata and Flavocetraria minuscula are new to Canada and Adelococcus alpestris new to the United States. We further place the following five names into synonymy: Lecania disceptans (Nyl.) Lynge [= Halecania alpivaga (Th.Fr.) M.Mayrhofer], Lecidea pallidella Nyl. [= Lecania subfuscula (Nyl.) S.Ekman], Lempholemma triptodes (Nyl.) Zahlbr. Leciophysma finmarkicum Th.Fr.), Polyblastia obtenta (Nyl.) Lynge [= Sporodictyon terrestre (Th.Fr.) S.Savic & Tibell], and Verrucaria pernigrata Nyl. [= Protothelenella sphinctrinoides (Nyl.) H.Mayrhofer & Poelt]. We propose restoring the long overlooked taxon Polyblastia exalbida (Nyl.) Zahlbr., currently known only from Alaska, to the North American lichen checklist. Finally, we propose the new combination Puttea caesia (Fr.) M.Svensson & T.Sprib. to replace Lecidea symmictella Nyl., which becomes a synonym.

- Biatora alnetorum S. Ekman & Tonsberg, a lichenised ascomycete in the family Ramalinaceae (Lecanorales, Lecanoromycetes), is described as new to science. It is distinct from other species of Biatora in the combination of mainly three-septate ascospores, a crustose thallus forming distinctly delimited soral is that develop by disintegration of convex pustules and the production of atranorin in the thallus and apothecia. The species is known from the Pacific Northwest of North America, where it inhabits the smooth bark of Alnua alnobetula subsp. sinuata and A. rubra. Biatora alnetorum is also a new host for the lichenicolous ascomycete Sclerococcum toensbagii Diederich.

Tidskriftsartikel (refereegranskat)abstract
- We discuss the taxonomy of three species of Bacidia occurring in insular Laurimacaronesia. Two of them, B. amylothelia (Vain.) Vain. and B. endoleucoides (Nyl.) Zahlbr., which were previously described from Angola and Madeira, respectively, are found here to belong in Bacidia s. str. (Ramalinaceae). Modern descriptions and illustrations are provided for the first time. Bacidia amylothelia is similar to B. areolata Gerasimova & A. Beck, B. campalea (Tuck.) S. Ekman & Kalb, B. fusconigrescens (Nyl.) Zahlbr., B. heteroloma (Vain.) Zahlbr., B. millegrana (Taylor) Zahlbr. and B. suffusa (Fr.) A. Schneid. and is reported here from the Canary Islands. Bacidia endoleucoides is most likely to be confused with B. absistens (Nyl.) Arnold, B. friesiana (Hepp) Korb., B. salazarensis B. de Lesd. and B. caesiovirens S. Ekman & Holien and was found to be widely distributed in the Canary Islands and Azores in addition to Madeira. The third species, Bacidia deludens S. Ekman, Tonsberg & van den Boom, is described here as new to science. Bacidia deludens is characterised by a greyish, crustose thallus with whitish soralia, pale apothecia with crystals in the hymenium and proper exciple, acicular ascospores with 3-19 septa, and the production of fumarprotocetraric acid as the consistently present major substance. It is described here from the Canary Islands and Madeira. Although conservatively treated here in Bacidia, we argue that it is likely to belong in the Malmideaceae. An identification key to all known species of Bacidia s. str. in insular Macaronesia is provided.

- From a population-based registry, 35 patients with histologically verified testicular lymphomas were identified: diffuse large B-cell lymphomas (DLBCL) in 33 and peripheral T-cell lymphomas in two cases. Twenty-two patients had localized disease (Pe stage I and II). Twenty-eight patients received systemic chemotherapy, 17 of whom also received intrathecal prophylaxis, and 12 out of these 17 also received radiotherapy to the contralateral testis. In the Pe stage I/II group, 7 out of 21 patients in complete remission (CR) relapsed. In 5 of them the CNS was involved (isolated CNS relapse in three). Remarkably late relapses occurred (up to 127 months). Intrathecal prophylaxis seemed to reduce the frequency of relapses involving the CNS, but the relatively short follow-up (median 45 months, range 34-88, for censored patients) prevents firm conclusions regarding efficacy. The outcome for the stage IV patients was poor, with only 1 out of 11 patients in continuous CR. Immunohistochemical analysis of the DLBCL tumours revealed that 31% had the germinal centre B-cell-like phenotype. CD44 was expressed in all the tumours of stage IV patients but in less than half of the Pe stage I/II patients. A high intratumoural microvessel density was correlated with a high degree of Ki-67 positive tumour cells and an inferior overall survival.

- PURPOSE/OBJECTIVES: To describe, from an interdisciplinary perspective, how cancer-related symptoms are assessed and managed in a cancer care setting and to describe the components that influence symptom management. DESIGN: Descriptive, qualitative, and cross-sectional. SETTING: An oncology and hematology department in a university hospital in western Sweden. SAMPLE: 31 nurses, physicians, physical therapists, dietitians, occupational therapists, and a medical social worker who all cared for patients with cancer-related symptoms. METHODS: Data were collected in focus groups and analyzed using content analysis. MAIN RESEARCH VARIABLES: Cancer-related symptoms and symptom management. FINDINGS: Symptom management, from a clinician's perspective, is a process involving different components. Four themes emerged from the data analysis: creating a relationship with the patient, understanding the patient, assessing the symptoms, and cooperating as a team. CONCLUSIONS: This study highlights several components that should be discussed in an effort to enhance symptom management. Discussion will help ensure that barriers to effective symptom management are acknowledged and addressed when implementing clinical routines designed to enhance management of different symptoms. In addition, these components should be acknowledged in the interest of facilitating adherence to symptom management strategies. Whether these components are important factors from patients' perspectives remains unknown. IMPLICATIONS FOR NURSING: Enhancing symptom management is not only a matter of implementing clinical guidelines; it must be preceded by teamwork, assessment, and evaluation method discussions and the ability to create a relationship with the patient. Nurses should be aware that their understanding of a patient affects their assessment of that patient's symptom experience.

Gut toxicity during hemopoietic stem cell transplantation may predict acute graft-versus-host disease severity in patients.

- Graft-versus-host disease (GVHD) is the primary complication of allogeneic, hemopoietic, stem cell transplantation (HSCT). Murine models suggest that gut toxicity, induced by the intensive chemotherapy preceding hematopoietic stem cell infusion, aggravates systemic GVHD. In HSCT patients gut toxicity correlates with chemotherapy intensity. The present study investigates acute GVHD severity and intestinal toxicity in patients undergoing allogeneic HSCT. In 38 patients intestinal permeability was assessed before and after chemotherapy (on days -1, +4, +7 and +14 as related to the stem cell infusion). Cumulative acute GVHD (days 0-100) and clinical intestinal toxicity (days 0-14) were evaluated in parallel. Patients with mild, acute GVHD (grades 0-I) had better-preserved intestinal barrier function (P=0.04) and less pronounced cumulative clinical intestinal toxicity (P=0.02) compared with patients with more severe acute GVHD (grades II-IV). Gut toxicity predicts acute GVHD severity. Therefore, gut protective strategies may diminish GVHD severity in allogeneic HSCT patients.

A population-based study of 135 lymphomas after solid organ transplantation : The role of Epstein-Barr virus, hepatitis C and diffuse large B-cell lymphoma subtype in clinical presentation and survival.
- 2014

Ingår i: Acta Oncologica. - 0284-186X .- 1651-226X. ; 53:5, s. 669-679

- Background. Epstein-Barr virus (EBV) plays a major role in the development of post-transplant lymphoproliferative disorder (PTLD), but there is an increasing awareness of EBV-negative PTLD. The clinical presentation of EBV-negative PTLD has not been as well characterised as EBV-positive cases. Further, there is limited knowledge on the clinical importance of diffuse large B-cell lymphoma (DLBCL) cell of origin subtype post-transplant. Materials and methods. We studied the role of EBV, hepatitis C (HCV) and DLBCL subtype in clinical presentation and survival in 135 post-transplant lymphomas diagnosed 1980-2006 in a population-based cohort of 10 010 Swedish solid organ transplant recipients. The lymphomas were re-evaluated according to WHO 2008, examined for EBV, and clinical data were collected from medical records. Results. Lymphoma incidence rate was 159/100 000 person-years and is also reported by lymphoma subtype. EBV-negative lymphomas constituted 48% and were associated with HCV infection (p = 0.02), bone marrow involvement (p < 0.001), and T-cell phenotype (p = 0.002). Among DLBCL, 78% were of non-germinal centre subtype, which was associated with EBV-positivity (69%, p = 0.001), early occurrence (p = 0.03), heart/liver/lung/pancreas recipients (p = 0.02), anti-T-cell globulin (p = 0.001), and tacrolimus treatment (p = 0.02). DLBCL subtypes had similar overall survival. Five-year overall survival was 42% in all treated patients. Independent poor prognostic factors were older age, B symptoms, ECOG 2-4, kidney/pancreas/heart recipients, T-cell lymphoma, and HCV-infection. Conclusions. With long follow-up, a large part of PTLD is EBV-negative, due to a high proportion of T-cell lymphomas and low of polymorphic PTLD. EBV-negative PTLD have a different clinical presentation. HCV may play an aetiological role in late-onset PTLD and was revealed as a new prognostic factor for inferior survival that needs to be confirmed in larger studies. The heavier immunosuppression in non-kidney transplantations seems to play a role in the development of non-germinal centre DLBCL. DLBCL cell of origin subtype lacks prognostic importance in the transplant setting.

- Objective:To evaluate treatment outcome in a large population-based cohort of patients with anal cancer treated according to Nordic guidelines.Material:Clinical data were collected on 1266 patients with anal squamous cell carcinoma diagnosed from 2000 to 2007 in Sweden, Norway and Denmark. 886 of the patients received radiotherapy 5464 Gy with or without chemotherapy (5-fluorouracil plus cisplatin or mitomycin). according to different protocols, stratified by tumor stage.Results:High age, male gender, large primary tumor, lymph node metastases, distant metastases, poor performance status, and non-inclusion into a protocol were all independent factors associated with worse outcome. Among patients treated according to any of the protocols, the 3-year recurrence-free survival ranged from 63% to 76%, with locoregional recurrences in 17% and distant metastases in 11% of patients. The highest rate of inguinal recurrence (11%) was seen in patients with small primary tumors, treated without inguinal irradiation.Conclusions:Good treatment efficacy was obtained with Nordic, widely implemented, guidelines for treatment of anal cancer. Inguinal prophylactic irradiation should be recommended also for small primary tumors. (C) 2014 Elsevier Ireland Ltd. All rights reserved.

- A taxonomic and biogeographic overview of the genus Myrionora is provided. Two species are recognized, M. albidula (Willey) R. C. Harris and M. pseudocyphellariae (Etayo) S. Ekman & Palice comb. nov. The genus is characterized by polysporous asci, the presence of crystals in the hymenium and proper exciple that partly consist of lobaric acid, and a photobiont with large cells (mostly in the range 12-20 mu m). Myrionora albidula is currently known from Germany, Norway, Sweden, the Russian Federation (Altayskiy Kray, Chelyabinskaya Oblast', Khabarovskiy Kray and Zabaykal'skiy Kray), and the United States (Alaska, Connecticut, Maine and Massachusetts). It inhabits bark of deciduous trees and shrubs and conifers over a wide range of latitudes. Myrionora pseudocyphellariae is known from Chile and Ecuador, where it has been encountered on lichens and decaying bark. Based on morphological characteristics, we conclude that Myrionora belongs in the Ramalinaceae.

Tidskriftsartikel (refereegranskat)abstract
- Recent surveys of the inland rain forests of British Columbia and adjacentregions have brought to light an unexpectedly rich epiphytic lichen flora, including severalspecies apparently new to science. In the first of a series of papers, we describe eight speciesdiscovered during these surveys as new: Absconditella amabilis T. Sprib. (Ostropales),Bacidina contecta S. Ekman & T. Sprib., Biatora aureolepra T. Sprib. & Tønsberg, Biatoraligni-mollis T. Sprib. & Printzen (all Lecanorales), Collema coniophilum Goward(Peltigerales), Pertusaria diluta C. Bjo¨rk, G. Thor & T. Wheeler (Pertusariales), Schaereriabrunnea C. Bjo¨rk, T. Sprib. & T. Wheeler (Ostropomycetidae incertae sedis) andScoliciosporum abietinum T. Sprib. (Lecanorales). We also call attention to a ninth species,Bacidina sp. A, a poorly known and possibly undescribed colonizer of moribundcyanolichens. A majority of the above species appear to be confined to old-growth forests,while two (Biatora ligni-mollis and Schaereria brunnea) are currently known only from‘‘antique’’ forests older than about 500 years. Many additional undescribed epiphyticlichens are known from inland rain forests, underscoring the need for further baselinebiodiversity research in light of its ongoing disappearance as a result of resource extraction.In addition to the eight new species, we report Absconditella celata as new to NorthAmerica, Absconditella lignicola as new to Canada and Montana, Bacidina chloroticula asnew to British Columbia and Gyalideopsis piceicola as new to Montana.

- Lichens are widely acknowledged to be a key component of high latitude ecosystems. However, the time investment needed for full inventories and the lack of taxonomic identification resources for crustose lichen and lichenicolous fungal diversity have hampered efforts to fully gauge the depth of species richness in these ecosystems. Using a combination of classical field inventory and extensive deployment of chemical and molecular analysis, we assessed the diversity of lichens and associated fungi in Glacier Bay National Park, Alaska (USA), a mixed landscape of coastal boreal rainforest and early successional low elevation habitats deglaciated after the Little Ice Age. We collected nearly 5000 specimens and found a total of 947 taxa, including 831 taxa of lichen-forming and 96 taxa of lichenicolous fungi together with 20 taxa of saprotrophic fungi typically included in lichen studies. A total of 98 species (10.3% of those detected) could not be assigned to known species and of those, two genera and 27 species are described here as new to science: Atrophysma cyanomelanos gen. et sp. nov., Bacidina circumpulla, Biatora marmorea, Carneothele sphagnicola gen. et sp. nov., Cirrenalia lichenicola, Corticifraga nephromatis, Fuscidea muskeg, Fuscopannaria dillmaniae, Halecania athallina, Hydropunctaria alaskana, Lambiella aliphatica, Lecania hydrophobica, Lecanora viridipruinosa, Lecidea griseomarginata, L. streveleri, Miriquidica gyrizans, Niesslia peltigerae, Ochrolechia cooperi, Placynthium glaciale, Porpidia seakensis, Rhizocarpon haidense, Sagiolechia phaeospora, Sclerococcum fissurinae, Spilonema maritimum, Thelocarpon immersum, Toensbergia blastidiata and Xenonectriella nephromatis. An additional 71 'known unknown' species are cursorily described. Four new combinations are made: Lepra subvelata (G. K. Merr.) T. Sprib., Ochrolechia minuta (Degel.) T. Sprib., Steineropsis laceratula (Hue) T. Sprib. & Ekman and Toensbergia geminipara (Th. Fr.) T. Sprib. & Resl. Thirty-eight taxa are new to North America and 93 additional taxa new to Alaska. We use four to eight DNA loci to validate the placement of ten of the new species in the orders Baeomycetales, Ostropales, Lecanorales, Peltigerales, Pertusariales and the broader class Lecanoromycetes with maximum likelihood analyses. We present a total of 280 new fungal DNA sequences. The lichen inventory from Glacier Bay National Park represents the second largest number of lichens and associated fungi documented from an area of comparable size and the largest to date in North America. Coming from almost 60 degrees N, these results again underline the potential for high lichen diversity in high latitude ecosystems.
