  Background: Patients with Crohn's disease (CD) are most often diagnosed as young adults; therefore, long-term studies are needed to assess the risk of cancer over their lifetime. Thus, the aims of the present study were to determine the risk of cancer in a Norwegian population-based cohort (the Inflammatory Bowel South Eastern Norway [IBSEN] study), 30 years after diagnosis, and to assess whether patients with CD were at an increased risk of specific cancer types. Methods: The IBSEN cohort prospectively included all incident patients diagnosed between 1990 and 1993. Data on cancer incidence were obtained from the Cancer Registry of Norway. Overall and cancer-specific hazard ratios (HRs) for CD patients compared with age- and sex-matched controls were modeled using Cox regression. Standardized incidence ratios (SIRs) were estimated compared to the general population. Results: In total, the cohort included 237 patients with CD, and 36 of them were diagnosed with cancer. Compared to the general Norwegian population, patients with CD had an increased overall risk of cancer (HR = 1.56, 95% CI: 1.06-2.28), particularly male patients (HR = 1.85, 95% CI: 1.08-3.16). The incidence of lung cancer and nonmelanoma skin cancer was increased; however, the difference was not statistically significant (SIR = 2.29, 95% CI: 0.92-4.27 and SIR = 2.45, 95% CI: 0.67-5.37, respectively). Conclusions: After 30 years of follow-up, the risk of all cancers in patients with CD was increased compared to the general population. Keywords: Cancer; Crohn’s disease. © The Author(s) 2023.

  Patients with inflammatory bowel disease report multiple symptoms, but the relationships among co-occurring symptoms are poorly understood. This study aimed to examine the prevalence of symptoms and explore symptom clusters and possible associations between symptom clusters and socio-demographic and clinical variables in patients newly diagnosed with inflammatory bowel disease. Methods The IBSEN III study is a prospective population-based inception cohort of patients with inflammatory bowel disease. This study used patient data from the three largest hospitals in the study catchment area. The Memorial Symptom Assessment Scale was used to assess the prevalence of symptoms. Symptom clusters were identified using principal component analysis. Possible associations between socio-demographic and clinical variables and symptom cluster membership were estimated using regression analysis. Results Of the 573 patients (age, ≥18 years) diagnosed with inflammatory bowel disease, 350 (61.1%) completed the questionnaire (responders). Eleven symptoms were reported by >50% of the responders. The three most prevalent symptoms were bloating (84%), drowsiness (81%), and lack of energy (81%). Three symptom clusters were identified: psychological (56% of the patients), impaired energy (28%), and physical (16%) clusters. Multinomial regression analysis revealed that vitamin D deficiency was significantly associated with the impaired energy cluster (odds ratio=2.49, 95% confidence interval [1.00-6.2], p=0.05). Conclusions We found high symptom prevalence in patients newly diagnosed with inflammatory bowel disease. Three distinct symptom clusters were identified, and the psychological cluster includes >50% of the patients. Vitamin D deficiency is the only factor associated with cluster membership, namely the impaired energy cluster.

  Objectives: Patients with ulcerative colitis (UC) have shown an increased risk for colorectal cancer, hepatobiliary, hematologic, and skin cancers, but updated long-term data is needed. This study aimed to estimate the risk of cancer in patients with UC compared to the general Norwegian population, in a population-based cohort (the IBSEN study), 30 years after diagnosis; and to identify possible risk factors associated with cancer. Methods: The IBSEN cohort prospectively included all incident patients between 1990 and 1993. Cancer incidence data were obtained from the Cancer Registry of Norway. The overall and cancer-specific hazard ratios (HR) were modelled using Cox regression. Standardized incidence ratios were estimated compared to the general population. Results: In total, the cohort included 519 patients, and 83 cases were diagnosed with cancer. There was no statistically significant difference in the overall cancer risk (HR = 1.01, 95% CI: [0.79-1.29]) and colorectal cancer risk (HR = 1.37, 95% CI: [0.75-2.47]) between patients and controls. The incidence of biliary tract cancer was higher than expected (SIR = 9.84, 95%CI: [3.19-20.15]), especially when UC patients suffered from primary sclerosing cholangitis. Male UC patients were also more at risk of being diagnosed with hematologic malignancies (HR = 3.48, 95% CI: [1.55-7.82]). Being prescribed thiopurines was associated with a higher risk of cancer (HR = 2.03, 95% CI: [1.02-4.01]). Conclusions: At 30 years after diagnosis, the risk of all cancer in patients with UC was not significantly increased compared with the general population. However, the risks of biliary tract cancer and hematologic cancers were increased, particularly in male patients.

  Objective: The objective was to explore whether high workloads in neonatal intensive care units were associated with short-term respiratory outcomes of extremely premature (EP) infants born <26 weeks of gestational age. Methods: This was a population-based study using data from the Norwegian Neonatal Network supplemented by data extracted from the medical records of EP infants <26 weeks GA born from 2013 to 2018. To describe the unit workloads, measurements of daily patient volume and unit acuity at each NICU were used. The effect of weekend and summer holiday was also explored. Results: We analyzed 316 first planned extubation attempts. There were no associations between unit workloads and the duration of mechanical ventilation until each infant’s first extubation or the outcomes of these attempts. Additionally, there were no weekend or summer holiday effects on the outcomes explored. Workloads did not affect the causes of reintubation for infants who failed their first extubation attempt. Conclusion: Our finding that there was no association between the organizational factors explored and short-term respiratory outcomes can be interpreted as indicating resilience in Norwegian neonatal intensive care units.

  Background and Aims: Patients with longstanding inflammatory bowel disease [IBD] may be at an increased risk of death compared to the general population, especially elderly patients. The Inflammatory Bowel South-Eastern Norway [IBSEN] study has previously detected a small but not statistically significant increase in mortality 20 years after diagnosis. The aim of this study was to evaluate the overall and cause-specific mortality at 30 years of follow-up. Methods: The IBSEN cohort included 519 incident patients with ulcerative colitis [UC] and 237 patients with Crohn’s disease [CD] between 1990 and 1993, each matched with five controls. Death certificate data were obtained from the Norwegian Cause of Death Registry. The underlying causes of death were categorized into five groups: all cancers, gastrointestinal cancers, cardiovascular diseases, infections and all other causes. Hazard ratios [HRs] were modelled using Cox regression. Results: There was no statistically significant difference in the overall mortality rates. However, in patients with CD, male sex (HR = 1.65 [95% CI: 1.04–2.62]), onset after 40 years of age (HR = 1.72 [1.19–2.48]), colonic disease (HR = 1.57 [1.05–2.35]) and penetrating behaviour (HR = 3.3 [1.41–7.76]) were clinical factors associated with an increased mortality. IBD patients were at a higher risk of death due to cardiovascular disease: HR = 1.51 [1.10–2.08] for UC and 2.04 [1.11–3.77] for CD. When taking into account both the underlying and the immediate cause of death, infection was more frequent in patients with IBD. Conclusions: Overall, all-cause mortality rates were similar between patients with IBD and controls. However, clinicians should remain alert to cardiovascular diseases and infections, particularly in specific subgroups of CD patients.

  The aim of the study was to investigate first extubation attempts among extremely premature (EP) infants and to explore factors that may increase the quality of clinical judgement of extubation readiness. Design and method A population-based study was conducted to explore first extubation attempts for EP infants born before a gestational age (GA) of 26 weeks in Norway between 1 January 2013 and 31 December 2018. Eligible infants were identified via the Norwegian Neonatal Network database. The primary outcome was successful extubation, defined as no reintubation within 72 hours after extubation. Results Among 482 eligible infants, 316 first extubation attempts were identified. Overall, 173 (55%) infants were successfully extubated, whereas the first attempt failed in 143 (45%) infants. A total of 261 (83%) infants were extubated from conventional ventilation (CV), and 55 (17%) infants were extubated from high-frequency oscillatory ventilation (HFOV). In extubation from CV, pre-extubation fraction of inspired oxygen (FiO2) ≤0.35, higher Apgar score, higher GA, female sex and higher postnatal age were important predictors of successful extubation. In extubation from HFOV, a pre-extubation FiO2 level ≤0.35 was a relevant predictor of successful extubation. Conclusions The correct timing of extubation in EP infants is important. In this national cohort, 55% of the first extubation attempts were successful. Our results suggest that additional emphasis on oxygen requirement, sex and general condition at birth may further increase extubation success when clinicians are about to extubate EP infants for the first time.

  Background Limited access to supervision, feedback and quality learning experiences pose challenges to learning in the clinical setting for first-year nursing students who are beginning their clinical experiences. Prior studies have indicated that simulation training, as a partial replacement of clinical practice hours, may improve learning. However, there has been little research on simulation training integrated as a partial replacement during first-year students’ clinical practice in nursing homes. The primary aim of this study was to examine first-year nursing students’ knowledge acquisition and self-efficacy in integrating a partial replacement of clinical hours in nursing homes with simulation training. Its secondary aim was to examine perceptions of how learning needs were met in the simulated environment compared with the clinical environment. Design The primary aim was addressed using an experimental design that included pre- and post-tests. The secondary aim was investigated using a descriptive survey-based comparison. Methods First-year students at a Norwegian university college (n = 116) were asked to participate. Those who agreed (n = 103) were randomly assigned to the intervention group (n = 52) or the control group (n = 51). A knowledge test, the General Self-efficacy Scale and the Clinical Learning Environment Comparison Survey were used to measure students’ outcomes and perceptions. The data were analysed using independent samples t-tests, chi-square tests and paired samples t-tests. Results Knowledge scores from pre- to post-tests were significantly higher in the intervention group than in the control group with a medium to large effect size (p < 0.01, Hedges’ g = 0.6). No significant differences in self-efficacy were identified. Significant differences (p <  0.05) were observed between the simulated and the clinical environment with regard to meeting learning needs; effect sizes ranged from small and medium to large (Cohen’s d from 0.3 to 1.0). Conclusion Integrating the partial replacement of clinical hours in nursing homes with simulation training for first-year nursing students was positively associated with knowledge acquisition and meeting learning needs. These findings are promising with regard to simulation as a viable partial replacement for traditional clinical practice in nursing homes to improve learning.

  OBJECTIVES To evaluate the psychometric properties of the Norwegian version of the multidimensional fatigue inventory (MFI-20) in patients with inflammatory bowel disease. METHODS Participants were recruited from nine hospitals in the southeastern and western parts of Norway. Clinical and sociodemographic data were collected, and participants completed the MFI-20, as well as the Fatigue Questionnaire (FQ). In addition to a confirmatory factor analysis, validity, reliability, test-retest and responsiveness were evaluated. RESULTS In total, 410 patients were included. The Norwegian MFI-20 had an acceptable model fit when compared to the original five-dimensional structure. A positive correlation was observed between the dimensions of MFI-20 and the FQ. MFI-20 scores increased according to subjective disease activity, but no differences were observed when using a calprotectin cut-off < or > =250 µg/g mg/kg. All MFI-20 dimensions except ‘reduced motivation’ in both ulcerative colitis (UC) and Crohn’s disease (CD) patients had alpha Cronbach alpha values ≥70, and test-retest reliability revealed good to excellent values. Merely one dimension (Reduced activity) in UC patients reporting improvement did not reach the threshold for acceptable responsiveness according to Guyatt statistics. CONCLUSIONS The Norwegian version of MFI-20 is valid, reliable and responsive. The instrument can safely be used in studies using fatigue as an endpoint.

  Purpose The purpose of this study was to explore self-esteem and associations between self-esteem and sociodemographic, clinical, and psychological factors in patients with infammatory bowel disease (IBD), a disease of chronic relapsing infammation of the gastrointestinal tract. IBD symptoms, including pain, fatigue, and diarrhea, as well as potential life-long medical treatment and surgery, may be demanding, cause signifcant challenges, and infuence self-esteem. Methods In this cross-sectional multicenter study, participants were recruited from nine hospitals in the southeastern and western regions of Norway from March 2013 to April 2014. Data were collected using self-report questionnaires. Selfesteem was assessed by the Rosenberg Self-Esteem Scale, fatigue was assessed by the Fatigue Questionnaire, self-efcacy was assessed by the General Self-Efcacy Scale, and disease activity was assessed by the Simple Clinical Colitis Activity Index for ulcerative colitis (UC) and Harvey Bradshaw Index for Crohn’s disease (CD). Multiple linear regression analysis was applied to examine associations between self-esteem and sociodemographic, clinical, and psychological factors. Results In total, 411 of 452 (91%) patients had evaluable data and were included in this study. The mean scores on selfesteem, self-efcacy, total fatigue, anxiety, and depression were similar between UC patients and CD patients. Male gender, being employed, and higher self-efcacy were independently associated with higher self-esteem, whereas anxiety and depression were independently associated with lower self-esteem. Neither disease activity nor fatigue were associated with self-esteem in the fnal multiple regression analyses. Conclusion Patient-centered interventions that improve self-esteem and reduce anxiety and depression seem to be important to optimize IBD management.

  Background: Pain and vitamin D deficiency are common in inflammatory bowel disease (IBD). Disease activity, fatigue, frequent relapses, prior surgery and psychological factors all seem to influence the experience of pain in IBD. Vitamin D deficiency has been associated with muscle and skeletal pain. This study aimed to determine whether there is an association between vitamin D deficiency and severity of pain in patients with IBD, and to investigate the influence of other socio-demographic and psychological variables on the experience of pain. Methods: Patients with IBD were recruited from nine hospitals in Norway in a multicenter cross-sectional study. The Brief Pain Inventory (BPI) questionnaire was used to measure pain. Disease activity was assessed using clinical disease activity indices, C-reactive protein (CRP) and fecal calprotectin. Regression models were fitted to explore a possible association between 25-hydroxyvitamin D and pain severity. Results: Of 407 patients included in the analyses, 229 (56%) had Crohn's disease (CD) and 178 (44%) had ulcerative colitis (UC). Vitamin D deficiency was present in half (203/407) of patients. Presence of pain was reported by 76% (309/407). More severe pain was associated with female gender and increased disease activity scores, but not with increased CRP or fecal calprotectin. In CD, patients without prior intra-abdominal surgery reported more severe pain. In multivariate analyses, there was no association between 25-hydroxyvitamin D and pain severity. Conclusions: In this study, no significant association between pain severity and vitamin D deficiency was revealed in patients with IBD. Keywords: pain severity; patient reported outcomes; vitamin D deficiency.

  Bakgrunn: Mobile intensivsykepleiere (MIS) er etablert ved Oslo universitetssykehus, Ullevål, men det foreligger lite kunnskap om hvordan slike ressurser benyttes, og hva som karakteriserer oppdragene. Hensikt: Å kartlegge antall henvendelser til MIS i løpet av en seks måneders periode samt vurdere årsaker til henvendelser, tiltak fra MIS og antall innleggelser på intensivavdelingen. Metode: I perioden juni til desember 2015 registrerte vi henvendelser til MIS. Ved hvert oppdrag registrerte MIS sosiodemografiske og kliniske variabler på et registreringsskjema. Når dataene på registreringsskjemaet var mangelfulle, innhentet vi informasjon fra elektronisk pasientjournal (DIPS). Resultat: MIS fikk totalt 163 henvendelser i registreringsperioden. Av disse var 91 enten råd til postsykepleier eller hjelp til å håndtere ulike sykepleieprosedyrer (gruppe 1), mens 72 var knyttet til hovedsakelig respiratorisk (56,9 prosent) og sirkulatorisk (18,1 prosent) forverring hos pasienten (gruppe 2). De hyppigst anvendte tiltakene i gruppe 2 var følgende: O2-tilførsel, intravenøs væske, medikamenter, riktig sengeleie samt rådføring med MIS. Av pasienter i gruppe 2 ble 22,1 prosent overført til behandling på intensivavdelingen. Konklusjon: I de fleste tilfellene ble MIS tilkalt på grunn av forverret helsetilstand forårsaket av respiratorisk besvær. Fremtidige studier bør kartlegge hvorvidt MIS kan forebygge intensivinnleggelser.

  Aim To systematically review the literature on fatigue in people with type 1diabetes. Methods In the period from April - June 2015 and with an updated search in May 2016, eight electronic databases as well as the grey literature were searched. Studies of all types of design were included if they reported data on fatigue in adult people with type 1 diabetes. All studies were assessed for quality. Results Out of 4259 references (including grey literature), 10 papers were reviewed in full. Three of these papers investigated fatigue as the primary endpoint, and one was assessed to be high quality. Two papers provided a definition of fatigue. Prevalence estimates ranged from 23-40%, dependent on the cut-off used. Six different questionnaires were used to measure fatigue/vitality and these were only validated to a limited extent in a diabetes population. Several demographic, personal and clinical factors were associated with fatigue, but the results were conflicting. Conclusions Few studies have been published that investigate fatigue in type 1 diabetes and there is a large variability in findings due to different measurement methods and factors investigated. There is still an unmet need to understand what contributes to fatigue in these patients through rigorous research.

  Background and aim: Vitamin D deficiency is common in inflammatory bowel disease (IBD). The aims of the present study were to determine the prevalence of vitamin D deficiency and to identify clinical and epidemiological variables associated with vitamin D deficiency in an outpatient population with IBD. Methods: Participants were recruited from nine hospitals in the southeastern and western regions of Norway as part of an observational, multicentre study from March 2013 to April 2014. Clinical and epidemiological data were collected by interview and from medical records. All analyses of serum 25-hydroxyvitamin D (25-OH-D) were performed in the same laboratory. Results: In total, 49% (200/408) of the patients had a 25-OH-D concentration <50 nmol/L, including 53% (122/230) of the Crohn’s disease (CD) patients and 44% (78/178) of the ulcerative colitis (UC) patients. In CD patients, disease activity, measured as the HBI, was inversely associated with vitamin D deficiency. No such association was observed with the Simple Clinical Colitis Activity Index (SCCAI) scores in UC, but in UC patients, vitamin D deficiency was associated with elevated faecal calprotectin >100 mg/kg. In patients with CD, there were significantly more relapses during the previous year in patients with vitamin D deficiency. Conclusions: Vitamin D deficiency was common, especially in CD, and was associated with increased disease activity, a relapsing disease course and higher inflammatory activity.
