Abstract
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.

Abstract
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.

Abstract
A nation wide study on the microbial aetiology of cases of acute clinical mastitis in Swedish dairy cows was conducted with the aim to investigate changes in the microbial panorama compared to a previous study performed 1994-1995. Another aim was to investigate some agent-specific environmental and individual risk factors. Milk samples were collected from 987 udder quarter cases from 829 cows during six 2-month periods from May 2002 to April 2003, and data on risk factors and demography were collected at sampling by means of a questionnaire. In total, 1056 bacteriological diagnoses were made. The most frequently isolated bacterial species was Staphylococcus aureus constituting 21.3% of the diagnoses, followed by Escherichia coli (15.9%), Streptococcus dysgalactiae (15.6%), Streptococcus uberis (11.1%), coagulase-negative staphylococci (6.2%), Arcanobacterium pyogenes (6.1%) and Klebsiella spp. (4.2%). Samples with no growth or contamination constituted 10.6% and 4.5% of the diagnoses, respectively. A major shift in the panorama of udder pathogens was not observed compared to the survey in 1994-1995. Isolation of Klebsiella spp. was strongly associated with the use of sawdust as bedding material. On the other hand, using sawdust as bedding reduced the risk of isolating S. uberis relative to using straw or peat. The risk of isolating E. coli increased with increasing milk yield and was higher in loose housing systems than in tie stalls. Isolation of S. aureus was associated with tie stalls, and A. pyogenes with low yielding cows and teat lesions. S. dysgalactiae infections were also associated with teat lesions.

Abstract
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.

Risk factors associated with the incidence of veterinary-treated clinical mastitis in Swedish dairy herds with a high milk yield and a low prevalence of subclinical mastitis.

Abstract
We conducted a case-control study to investigate factors associated with the incidence rate of veterinary-treated clinical cases of mastitis (IRVTCM) in Swedish dairy herds with the overall objective to reduce the incidence of clinical mastitis (CM) and excessive use of antibiotics. Herds with documented high milk yield, low prevalence of subclinical mastitis and high (27.3-67.5 cases/100-cow years=case) or low (0.0-10.8 cases/100-cow years=control) IRVTCM were selected for this study. One hundred and fifty-eight herds participated. Logistic-regression models were used to assess statistically significant risk factors associated with a high or low IRVTCM. HI-herd farmers more often contacted a veterinarian for treatment of a cow with CM as soon as the milk appearance was altered, compared to LO-herd farmers that more often waited until the general condition of a cow was altered. HI-herd farmers also treated more cows due to high somatic-cell counts during lactation and/or at drying off. There were more high-yielding cows with dirty lower hind-legs, a higher percentage of first-parity cows and a higher incidence of veterinary-treated teat injuries in HI-herds. HI-herd farmers had their cows claw-trimmed more than once per year, compared to LO-herd farmers that had their cows claw-trimmed only once per year, and the condition of silage storage at HI-farms more often had one or more remarks. LO-herds consisted more often of cows of the Swedish Red and White breed, and their roughage diet was more often complemented with only commercial concentrates compared to HI-herds that more often fed grain in combination with commercial concentrates. The herds participating in this study were all well managed herds, and the attitude towards treatment and production seemed to influence the IRVTCM more than environmental factors.

Abstract
Fatigue--which is a complex, multicausal, and multidimensional subjective experience--is today the most frequently reported symptom from patients with cancer. The aim of this study was to explore the experience of fatigue in cancer patients and to describe the categories and dimensions of the symptoms. A qualitative method--grounded theory--was used. Unstructured, tape-recorded interviews with 15 cancer patients were used for data collection. The categories found in this study illustrate fatigue as a process. Three major categories were found: (1) experiences (of loss, need, malaise, psychological stress, emotional affection, abnormal weakness, difficulties in taking the initiative); (2) consequences (social limitation, affected self-esteem, affected quality of life); and (3) actions (coping). The categories were constructed on the basis of dimensions with subordinated qualities. Knowledge concerning the different expressions of fatigue is important in caring for patients with cancer. The results from this study may contribute to a better understanding of how a cancer patient can experience and express fatigue and how the symptoms may affect the patient.

Abstract
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.

Abstract
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 54-64Gy 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.

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.

Abstract
Eleven Swedish postpartum cows with retained fetal membranes (RFM) were studied to determine the intrauterine bacterial flora. Bacteriological examination was performed from twice weekly uterine biopsies. A total of 161 biopsies were collected during the first 8 weeks postpartum of which 82 (50.9%) were found with bacterial growth. Seventy-one of the 82 bacteria-positive biopsies (86.6%) showed mixed infections whereas the remaining 11 (13.4%) were pure cultures. Generally, a total of 322 isolates belonging to 12 different genera of bacteria, 6 facultative and 6 obligate anaerobic pathogens were identified. Mixed infections were most frequent for Actinomyces pyogenes together with obligate anaerobic bacteria, especially Bacteroides levii/spp. and Fusobacterium necrophorum. All of the studied cows had an infection that involved the first two genera of bacteria, whereas F. necrophorum was found in 8 of the 11 animals. The present work suggests that a possible pathogenic synergism between A. pyogenes and the two main Gram-negative anaerobes might have caused early endometritis and/or persistent infection.

Abstract
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.

Abstract
By studying carcass quality, expressed as affection, pathological findings, slaughter-weight and evaluation, a picture of an animal's health and potential as high quality food is achieved. This study compares the carcass quality in Swedish certified organic meat production with that of conventional meat production slaughtered during 1997. The study involves 3.9 million pigs, about 570,000 cattle and 190,000 sheep, all reared conventionally and 3483 pigs 4949 cattle and 4997 sheep reared according to organic standards. Pathological and additional findings are registered by meat inspectors from the Swedish National Food Administration at the post-mortem inspection. There was a significant difference at the post-mortem inspection of growing-fattening pigs; 28% of conventionally and 17% of the organically reared pigs had one or more registered lesion. The carcass evaluation of swine shows a higher meat percentage in conventional swine production. The total rate of registered abnormalities in cattle was systems around 28% from organic and 27% from conventionally reared herds. Carcass evaluation of cattle from organic herds gave higher classification in the EUROP system, whereas the fat content was lower than that of conventionally reared cattle. Sheep, reared both organically and conventionally, showed a lower rate of registered abnormalities than swine and cattle.

Abstract
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.

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.

Abstract
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.

Abstract
The efficacy of allogeneic, haemopoietic stem cell transplantation (HSCT) is limited by concomitant toxicity. This has led to the development of less toxic, reduced intensity conditioning (RIC) protocols, whose therapeutic benefit is largely related to an associated, immunity-mediated graft-versus-malignancy effect rather than by the cytotoxic treatment itself. Murine HSCT models suggests that acute graft-versus-host disease (GVHD) increases with the intensification of the conditioning regimen mediated by loss of integrity of the gut mucosa barrier. The present study was undertaken to investigate gastro-intestinal (GI) permeability during allogeneic HSCT with RIC. In 17 patients (myeloablative conditioning in nine, RIC in eight), intestinal permeability was assessed by a (51)Cr-EDTA absorption test before the start of cytotoxic treatment the day before stem cell infusion (day -1) and 4, 7 and 14 days after stem cell infusion. Patients receiving RIC did not develop any significant increase in intestinal permeability during the transplantation course but in myeloablatively conditioned patients there was a significant increase in intestinal permeability the day before the stem cell infusion (P < 0.005), on day 4 (P < 0.005), on day 7 (P < 0.01) and on day 14 (P < 0.005) after stem cell infusion, compared with the baseline. Myeloablative conditioning also revealed increased intestinal permeability on day 7 compared with the RIC (P < 0.05). The finding of preserved intestinal-barrier function during allogeneic HSCT with RIC is discussed, with reference to the hypothesis that GI tract damage may be an important initiating event of GVHD.

Abstract
The intensive cytotoxic treatment given in connection with bone marrow transplantations induces severe injury to the gut consistent with an increase in intestinal permeability. Currently, extent of the gut injury is assessed by inspecting the mouth and recording symptoms deriving from the gastro-intestinal tract. The aims of this study were to evaluate whether changes in permeability correlate with clinical assessment of gut toxicity, according to the WHO criteria, and also to examine the duration of intestinal permeability after high-dose chemotherapy. In 18 consecutive patients undergoing bone marrow transplantation, gastrointestinal permeability was assessed by a 51Cr-EDTA absorption test before the start of cytotoxic treatment, and 4, 7, 10 and 14 days after stem-cell infusion. In another seven patients, permeability was assessed 2 days after the start of cytotoxic treatment, and 1, 7 and 14 days after stem cell infusion. During the same period, oral- and non-oral clinical toxicity according to the WHO criteria were recorded. Permeability increased significantly 2 days after the start of cytotoxic treatment (P < 0.05), on day 1 (P < 0.05), on day 4 (P < 0.0005), on day 7 (P < 0.0005) and on day 10 (P < 0.005) after stem cell infusion, compared with pre-treatment permeability. Despite significant barrier dysfunction, clinical toxicity was very moderate in the early transplantation course. Gastro-intestinal, but not oral clinical toxicity requiring therapy, was consistent with a significant increase in permeability compared with no clinical toxicity or toxicity not requiring therapy. Similarly, cumulative gastro-intestinal, but not oral toxicity correlated positively with the increase in permeability. The permeability test was unable to predict the severity of the clinical gastro-intestinal toxicity.

Abstract
The health and housing of the stock on 26 organic dairy herds in four counties in eastern Sweden were studied for one year. The herds ranged in size from 12 to 64 cows, and their milk production from 3772 to 10,334 kg per cow per year. A large-animal practitioner visited the farms three times during the year, and a random sample of a third of the cows in each herd were examined. The calves and young stock and their housing were also studied. The calves were in good condition in all but four herds; their serum immunoglobulins varied from almost none to high levels. The young stock were in good condition and in good housing in 20 herds. No cows with clinical signs of metabolic disorders were found. Body condition scores were adequate or good except in two herds. Acetone was analysed in milk samples from individual cows three to six weeks postpartum, and only sporadic cases with high levels were found. The incidence of diseases treated by a veterinarian was lower in the organic herds than the average for the conventional herds in the local dairy association. The findings at the farm visits supported these data, and it is evident that a good standard of health and welfare can be achieved in organic dairy herds.

Abstract
Milk leakage (ML), or milk observed dripping or flowing from one or more teats between milkings, has been associated with increased risk of udder infections and mastitis in dairy cows. Preliminary observations indicate that ML might occur more often in automatic milking systems (AMS) than in conventional milking systems (CMS), but comparative data on the incidence of ML in AMS or in CMS are not available. Therefore, the occurrence of ML at various observation periods was studied in one AMS with cows housed in a free-stall barn in comparison to CMS with cows housed either in a free-stall barn or a tie-stall barn and milked at regular intervals in a herringbone milking parlor. Relationships between ML and other cow and management factors were also examined. In each of 2 yr, all cows (n = 230 total; 46 cows present both years) were observed at 2-h intervals during six 24-h periods. At least one ML occurred in 39.0 (AMS) vs. 11.2% (CMS) of individual cows and in 16.2 (AMS) vs. 2.9% (CMS) of 24-h cow days studied. Milk leakage was not related to milk production, parity, stage of lactation, or estrous status. However, in the AMS, 62% of primiparous and 28% of multiparous cows leaked milk at least once. Milk leakage occurred more often in rear than in forequarters. Cows were usually lying down when ML was observed, but intervals from previous milking varied, especially in AMS. In AMS, about one-fifth of the ML observations occurred < or = 4 h after milking, and half of those were associated with disturbances at the previous milking. Milk flow rate was higher in quarters leaking milk than in other quarters. Strategies to reduce milk leakage in AMS may be important to minimize potential risks of udder disease.

Abstract
The aim of this study was to describe the potential application of ultrasound in combination with the rectal palpation method and to compare the results to determine the involution period in 11 Swedish dairy cows with retained fetal membranes (RFM). The animals were examined three times a week during the first 8-week postpartum (PP) period. Significant quantity of abnormal vaginal discharges with concomitant accumulation of snowy fluid and thickening of the endometrial and uterine walls were interpreted as evidence of endometritis. The discharges decreased most markedly during the third week PP concomitantly with a marked decrease in the cervical and uterine size. Resumption of cyclical ovarian activity occurred within a month in 7 animals. Five of these cows had 2 ovulations and two animals had 1 and 3 ovulations, respectively. A slight increase of the cervix and uterine size was observed in all ovulating animals in relation to the oestrous periods. Several different calculation methods of the ultrasonographic results were evaluated to describe the completion of uterine involution and compared with findings at rectal palpation. The best congruency with rectal palpation was found to use a 0.5 cm difference for comparison of the previous pregnant and non-pregnant uterine horns in singleton cows and an 80% reduction of the uterine size in all studied animals.

Abstract
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.

Abstract
BACKGROUND The association between cancer-related fatigue and pathological processes in the body is largely unknown. This study was designed to investigate a possible linkage between fatigue and intestinal injury during pelvic radiotherapy. METHODS Twenty-nine women undergoing pelvic radiotherapy for anal or uterine cancer were prospectively followed. Fatigue and diarrhea were assessed using patient self-reported questionnaires. Plasma citrulline concentration, as a sign of intestinal injury, and C-reactive protein, orosomucoid, albumin, α(1)-antitrypsin, and haptoglobin, as signs of systemic inflammation, were analyzed. RESULTS Fatigue increased significantly (p < .001) and citrulline decreased significantly (p < .001) during treatment. A significant negative correlation (r = -0.40; p < .05) was found between fatigue and epithelial atrophy in the intestine (as assessed by plasma citrulline) after 3 weeks of treatment and a significant positive correlation (r = 0.75; p < .001) was found between fatigue and diarrhea. Signs of systemic inflammation were evident, with significant increases in serum orosomucoid, serum haptoglobin (p < .05) and serum α(1)-antitrypsin (p < .001) and a significant decrease in serum albumin (p < .001). CONCLUSION The present study indicates a link between fatigue and intestinal injury during pelvic radiotherapy. This observation should be considered as a preliminary finding because of the small sample size but may serve as a rationale for therapeutic interventions aimed at alleviating both fatigue and gastrointestinal symptoms during pelvic radiotherapy.

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.

Abstract
Gastroparesis may be involved in the pathophysiology of prolonged nausea and vomiting after haemopoietic stem-cell transplantation (HSCT), but this has not been prospectively investigated. Gastric emptying (GE) was investigated in 20 patients before and 2 months after autologous HSCT. Gastrointestinal symptoms were graded prospectively and oral energy intake was recorded in parallel. Before transplant, all patients were asymptomatic and GE was within the reference range. Post transplant GE was delayed in three patients and three patients reported nausea and/or vomiting. Neither gastrointestinal symptoms nor oral energy intake post transplant discriminated between patients with or without delayed GE. Oral energy intake before transplant was lower (P=0.05), and there was a greater need for total parenteral nutrition (TPN) among patients who developed gastroparesis post transplant (P<0.05). Delayed GE after HSCT was found to be less common than had been believed from retrospective studies. Gastroparesis may be involved in some cases of prolonged nausea and vomiting after autologous HSCT but alternative explanations should be considered. Symptoms consistent with gastroparesis did not correlate with GE. Patients at risk of developing gastroparesis may be found among those with nutritional difficulties before and during the transplant course.
