Journal article (peer-reviewed)abstract
- 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.

Oceanic and atmospheric modes in the Pacific and Atlantic Oceans since the Little Ice Age (LIA): Towards a synthesis
- 2019

Journal article (peer-reviewed)abstract
- Understanding the variability of the oceanic and atmospheric modes from the Little Ice Age (LIA,similar to 1250 - 1850) to the present can help evaluate their behaviors under future warming scenarios. Numerous proxy-based reconstructions of the oceanic and atmospheric modes were presented. It is highly needed for a synthesis study to evaluate the existing reconstructions of the dominant oceanic and atmospheric modes since the LIA. We found that the El Nino-Southern Oscillation (ENSO) reconstructions are only robust on interannual and interdecadal scales, while the reconstructed Pacific Decadal Oscillation (PDO) and Atlantic Multi-decadal Oscillation (AMO) are robust on multi-decadal (50-100 years) timescales. We generated synthesized ENSO, PDO and AMO reconstructions as the average of the existing reconstructions on the most suitable timescales identified using timescale dependent correlation methods. In the 20th century, the interannual variability and periodicity of the ENSO and the multi-decadal periodicity of the PDO and AMO were most pronounced. The ENSO shows the strongest multi-decadal periodicity from mid-18th century onwards, while the multi-decadal periodicity of the PDO and AMO was particularly low in the 18th century. Multi-decadal variations of the AMO showed a prompt and positive response to solar irradiation, while the ENSO showed a lagged and negative response to solar irradiation from the 18th century to the present.

Practical Viewpoints on the Diagnosis and Management of Heparin-Induced Thrombocytopenia
- 2011
-
In: Seminars in Thrombosis and Hemostasis. - : Georg Thieme Verlag KG. - 1098-9064 .- 0094-6176. ; 37:3, s. 328-335

Journal article (peer-reviewed)abstract
- Heparin-induced thrombocytopenia (HIT, type II) is an immune-mediated disorder due to antibodies formed against heparin platelet factor 4 complexes, usually appearing at days 5 to 14 after initiation of heparin. It is important to recognize HIT because heparin prophylaxis or treatment paradoxically associates with new venous and/or arterial thrombosis. Early clinical suspicion and diagnosis together with proper pharmacotherapy and close laboratory monitoring are the cornerstones for successful management. This includes monitoring of Thrombocytopenia, its Timing to heparin administration, appearance of new Thrombosis or resistance to treatment, and differential diagnosis by exclusion of oTher causes (the 4T's). Specific attention should be paid to the absence or presence of thrombosis and to tailoring thromboprophylaxis or anticoagulant therapy with a nonheparin alternative. Even in the absence of HIT-associated thrombosis, an active policy for prolonged thromboprophylaxis is demanded. Rapid and reliable assays should be developed for diagnosis and anticoagulation monitoring to secure safe management with nonheparins. Semiquantitative testing for on-call hours should be available and later confirmed as clinically needed. Alternative therapeutic options are available, but because their use is infrequent, experienced coagulation treatment centers should provide guidance in the treatment and in laboratory monitoring. Most of the evidence in HIT is grade IC, and thus the best evidence is provided by clinical experience. New anticoagulants and platelet inhibitors may offer future alternatives in the management of HIT, but the current treatment options provide the best experience and benefit. The joint clinical and laboratory guidelines provided in this article along with two practical case scenarios were prepared by a Nordic expert panel. They will be valuable for hematologists and colleagues who do not routinely encounter HIT.

Appearance of hepatobiliary diseases in a population-based cohort with inflammatory bowel diseases (Inflammatory Bowel Disease Cohort of the Uppsala Region)
- 2015

Journal article (peer-reviewed)abstract
- Background and AimTo prospectively follow the evolution of hepatobiliary diseases in a population-based cohort of patients with inflammatory bowel diseases. MethodsBetween 2005 and 2009, 790 incident cases of ulcerative colitis and Crohn's disease were registered in the Uppsala Health Region, corresponding to an average incidence of 20.0 and 9.9 new cases/100000 inhabitants/year, respectively. Liver function tests were analyzed in 97.1% and the results of ensuing investigations were summarized. ResultsSeventeen patients with primary sclerosing cholangitis were diagnosed corresponding to an overall prevalence of 2.2% (ulcerative colitis 1.7% and Crohn's disease 3.0%, respectively). The median age at diagnosis was 25 years (interquartile range: 17.0-34.0). Among the 92 patients below 17 years of age, three had autoimmune hepatitis and three primary sclerosing cholangitis, summing up to a prevalence of 6.5% immune-mediated hepatobiliary diseases among the pediatric patients. Three patients have undergone liver transplantation and one died of colonic carcinoma. Ten patients have demonstrated persistent elevation of alkaline phosphatases but had a normal magnetic resonance cholangiopancreatography (two patients) or refused further investigation (one patient). ConclusionIn this first large prospective population-based cohort of 526 patients with ulcerative colitis (UC) and 264 with Crohn's disease, 17 cases of primary sclerosing cholangitis were found, among whom three (17%) so far have been liver transplanted and one has died of colon carcinoma. The average age of those affected by primary sclerosing cholangitis is considerably lower than usually reported. Ten patients had or have had elevated alkaline phosphatase without confirmed liver or biliary disease.

Journal article (peer-reviewed)abstract
- Objective. Inflammatory bowel disease (IBD), microscopic colitis and celiac disease are all diseases with worldwide distribution and increased incidence has been reported from many areas. There is a shortage of studies investigating the occurrence of these diseases in the same individual and whether those affected demonstrate any particular phenotype. The aim of the study was to describe the concomitant incidence of microscopic colitis and celiac disease in a population-based IBD cohort. Methods. All 790 individuals in a prospective population-based cohort included 2005-09 from Uppsala region, Sweden, were reviewed regarding the appearance of microscopic or celiac disease before or after IBD diagnosis. Results. Fifty percent (396/790) of the patients had been examined for the possibility of celiac disease. Seventeen patients with celiac disease were found, representing 2.2% of the cohort. Patients with celiac disease were younger compared to the non-celiac patients and those with colitis had more often an extensive inflammation of the colon. Seventy-one percent (12/17) were women. The majority of the patients were diagnosed with celiac disease before IBD. Five patients with IBD had an earlier diagnosis of microscopic colitis or developed it after the IBD diagnosis. One teenager developed collagenous sprue, misinterpreted as a severe relapse of ulcerative colitis (UC) resulting in colectomy. Conclusions. The risk for celiac disease seems not to be increased in IBD, but those affected by both diseases seem to be predominantly women with extensive UC. There is a potential association between microscopic colitis and IBD.
