- Background: We aimed to evaluate differences in outcome between patients admitted to intensive care unit (ICU) after elective versus acute surgery in a multinational cohort of very old patients (80 years; VIP). Predictors of mortality, with special emphasis on frailty, were assessed.Methods: In total, 5063 VIPs were induded in this analysis, 922 were admitted after elective surgery or intervention, 4141 acutely, with 402 after acute surgery. Differences were calculated using Mann-Whitney-U test and Wilcoxon test. Univariate and multivariable logistic regression were used to assess associations with mortality.Results: Compared patients admitted after acute surgery, patients admitted after elective surgery suffered less often from frailty as defined as CFS (28% vs 46%; p < 0.001), evidenced lower SOFA scores (4 +/- 5 vs 7 +/- 7; p < 0.001). Presence of frailty (CFS >4) was associated with significantly increased mortality both in elective surgery patients (7% vs 12%; p = 0.01), in acute surgery (7% vs 12%; p = 0.02).Conclusions: VIPs admitted to ICU after elective surgery evidenced favorable outcome over patients after acute surgery even after correction for relevant confounders. Frailty might be used to guide clinicians in risk stratification in both patients admitted after elective and acute surgery.

- Young breast cancer patients have a decreased survival rate and it has been demonstrated that young age is an independent predictor of adverse prognosis. Overexpression of c-erbB-2 protein (also known as HER-2/neu) has been shown to be a prognostic indicator in breast cancer in general and especially among patients with axillary nodal metastases. The present study was initiated to determine the prognostic significance of c-erbB-2 protein overexpression in early onset breast cancer.A population consisting of 110 young breast cancer patients, ≤ 36-year-old at diagnosis, was analyzed with immunohistochemical staining for c-erbB-2 protein.Thirty patients (27%) were found to overexpress the c-erbB-2 protein. C-erbB-2 positivity was significantly associated with poor survival when all patients were included in the analysis (P = 0.002) and for patients with axillary nodal metastases (P = 0.0007). No such association was found for node-negative patients. Furthermore, the difference in prognosis in relation to c-erbB-2 among node-positive patients was maintained, when these were stratified in groups treated or not treated with adjuvant chemotherapy.The study indicates that overexpression of c-erbB-2 protein is a strong prognostic factor in young breast cancer patients with axillary nodal metastases. Moreover, the adverse prognosis associated with c-erbB-2 overexpression in node-positive patients was observed whether or not the patients had received adjuvant chemotherapy.

- Antibiotic use and its implications have been discussed extensively in the past decades. This situation has global consequences when antibiotic resistance becomes widespread in the intestinal bacterial flora of stationary and migratory birds. This study investigated the incidence of fecal bacteria and general antibiotic resistance, with special focus on extended spectrum beta-lactamase (ESBL) isolates, in two species of seabirds at remote Easter Island. We identified 11 species of bacteria from masked booby (Sula dactylatra) and Christmas shearwater (Puffinus nativitatis); five species of gram-negative bacilli, four species of Streptococcus (Enterococcus), and 2 species of Staphylococcus. In addition, 6 types of bacteria were determined barely to the genus level. General antibiotic susceptibility was measured in the 30 isolated Enterobacteriaceae to 11 antibiotics used in human and veterinary medicine. The 10 isolates that showed a phenotypic ESBL profile were verified by clavulanic acid inhibition in double mixture discs with cefpodoxime, and two ESBL strains were found, one strain in masked booby and one strain in Christmas shearwater. The two bacteria harboring the ESBL type were identified as Serratia odorifera biotype 1, which has zoonotic importance. Despite minimal human presence in the masked booby and Christmas shearwater habitats, and the extreme geographic isolation of Easter Island, we found several multiresistant bacteria and even two isolates with ESBL phenotypes. The finding of ESBLs has animal and public health significance and is of potential concern, especially because the investigation was limited in size and indicated that antibiotic-resistant bacteria now are distributed globally.

- Background and aims: Anaemia is an important complication of inflammatory bowel disease (IBD). The aim of this study was to determine the prevalence of anaemia and the practice of anaemia screening during the first year following diagnosis in a European prospective population-based inception cohort.Methods: Newly diagnosed IBD patients were included and followed prospectively for one year in 29 European and 1 Australian centre. Clinical data including demographics, medical therapy, surgery and blood samples were collected. Anaemia was defined according to the World Health Organization.Results: A total of 1,871 patients (CD: 686, 88%; UC: 1,021, 87%; IBDU 164. 81%) were included in the study. The prevalence of anaemia was higher in CD than in UC patients and overall, 49% of CD and 39% of UC patients had at least one instance of anaemia during the first 12 months after diagnosis. UC patients with more extensive disease and those from Eastern European countries, and CD patients with penetrating disease or colonic disease location, had higher risks of anaemia. CD and UC patients in need of none or only mild anti-inflammatory treatment had a lower risk of anaemia. In a significant proportion of patients, anaemia was not assessed until several months after diagnosis, and in almost half of all cases of anaemia a thorough work-up was not performed.Conclusions: Overall, 42% of patients had at least one instance of anaemia during the first year following diagnosis. Most patients were assessed for anaemia regularly; however, a full anaemia work-up was frequently neglected in this community setting.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Mutations in the mismatch repair genes hMLH1 and hMSH2 predispose to hereditary non-polyposis colorectal cancer (HNPCC). Genetic screening of more than 350 Danish patients with colorectal cancer (CRC) has led to the identification of several new genetic variants (e.g. missense, silent and non-coding) in hMLH1 and hMSH2. The aim of the present study was to investigate the frequency of these variants in hMLH1 and hMSH2 in Danish patients with sporadic colorectal cancer and in the healthy background population. The purpose was to reveal if any of the common variants lead to increased susceptibility to colorectal cancer. METHODS: Associations between genetic variants in hMLH1 and hMSH2 and sporadic colorectal cancer were evaluated using a case-cohort design. The genotyping was performed on DNA isolated from blood from the 380 cases with sporadic colorectal cancer and a sub-cohort of 770 individuals. The DNA samples were analyzed using Single Base Extension (SBE) Tag-arrays. A Bonferroni corrected Fisher exact test was used to test for association between the genotypes of each variant and colorectal cancer. Linkage disequilibrium (LD) was investigated using HaploView (v3.31). RESULTS: Heterozygous and homozygous changes were detected in 13 of 35 analyzed variants. Two variants showed a borderline association with colorectal cancer, whereas the remaining variants demonstrated no association. Furthermore, the genomic regions covering hMLH1 and hMSH2 displayed high linkage disequilibrium in the Danish population. Twenty-two variants were neither detected in the cases with sporadic colorectal cancer nor in the sub-cohort. Some of these rare variants have been classified either as pathogenic mutations or as neutral variants in other populations and some are unclassified Danish variants. CONCLUSION: None of the variants in hMLH1 and hMSH2 analyzed in the present study were highly associated with colorectal cancer in the Danish population. High linkage disequilibrium in the genomic regions covering hMLH1 and hMSH2, indicate that common genetic variants in the two genes in general are not involved in the development of sporadic colorectal cancer. Nevertheless, some of the rare unclassified variants in hMLH1 and hMSH2 might be involved in the development of colorectal cancer in the families where they were originally identified.

Tidskriftsartikel (refereegranskat)abstract
- In this study, we examine the relationship between institutions of labour market and welfare states and two central aspects of job quality: autonomy and job security. Drawing on theoretical frameworks from varieties of capitalism and a power resource approach, we examine whether macro-level features can explain country differences in perceived autonomy and job security. In multi-level analyses, we combine institutional data with data from the European Social Survey (ESS), which contains information on 13,414 employees from 19 countries. We report three main findings: first, we find high autonomy in the Nordic countries and low autonomy and job security in transition countries; second, the institutional features-union density and skill specificity-are positively associated with autonomy; third, unemployment rate is the most important factor in explaining country differences in perceived job security. Our findings suggest that the power of workers and their skill specificity are important in explaining cross-country differences in autonomy. The study shows that a multi-level approach may help explain how institutions shape employment outcomes.
