- In a population-based study on cobalamin status and incident fractures in elderly men (n=790) with an average follow-up of 5.9years, we found that low levels of metabolically active and total cobalamins predict incident fractures, independently of body mass index (BMI), bone mineral density (BMD), plasma total homocysteine (tHcy), and cystatin C.

- Objective: To gain knowledge of underlying risk factors for vascular complications and their impact on life expectancy in myelofibrosis. Methods: From a cohort of 392 myelofibrosis patients registered in the Swedish MPN registry 58 patients with vascular complications during follow-up were identified. Patients with vascular complications were compared with both 1:1 matched controls and the entire myelofibrosis cohort to explore potential risk factors for vascular complications and their impact on survival. Results: Incidence of vascular complications was 2.8 events per 100 patient-years and the majority of complications were thrombotic. Patients with complications were significantly older and had lower hemoglobin when compared to the entire cohort. In the case–control analysis, no significant risk factor differences were observed. The major cause of death was vascular complications and median survival was significantly impaired in patients with vascular complications (48 months) compared to controls (92 months). Inferior survival in patients with vascular complications was found to be dependent on IPSS risk category in a Cox regression model. Conclusion: Vascular complications have a considerable impact on survival in MF. At diagnosis, risk assessment by IPSS does not only predict survival but is also associated with the risk of vascular complications.

- Background: Cerebral venous thrombosis (CVT) due to vaccine-induced immune thrombotic thrombocytopenia (VITT) is a severe condition, with high in-hospital mortality rates. Here, we report clinical outcomes of patients with CVT-VITT after SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) vaccination who survived initial hospitalization.Methods: We used data from an international registry of patients who developed CVT within 28 days of SARS-CoV-2 vaccination, collected until February 10, 2022. VITT diagnosis was classified based on the Pavord criteria. Outcomes were mortality, functional independence (modified Rankin Scale score 0-2), VITT relapse, new thrombosis, and bleeding events (all after discharge from initial hospitalization).Results: Of 107 CVT-VITT cases, 43 (40%) died during initial hospitalization. Of the remaining 64 patients, follow-up data were available for 60 (94%) patients (37 definite VITT, 9 probable VITT, and 14 possible VITT). Median age was 40 years and 45/60 (75%) patients were women. Median follow-up time was 150 days (interquartile range, 94-194). Two patients died during follow-up (3% [95% CI, 1%-11%). Functional independence was achieved by 53/60 (88% [95% CI, 78%-94%]) patients. No new venous or arterial thrombotic events were reported. One patient developed a major bleeding during follow-up (fatal intracerebral bleed).Conclusions: In contrast to the high mortality of CVT-VITT in the acute phase, mortality among patients who survived the initial hospitalization was low, new thrombotic events did not occur, and bleeding events were rare. Approximately 9 out of 10 CVT-VITT patients who survived the acute phase were functionally independent at follow-up.

- Objective Experimental data imply that endostatin, a proteolytically cleaved fragment of collagen XVIII, could be involved in the development of cardiovascular disease and cancer. Prospective data concerning the relation between circulating endostatin and mortality are lacking. Accordingly, we aimed to study associations between circulating endostatin and mortality risk. Approach and Results Serum endostatin was analyzed in 2 community-based cohorts: the Prospective Investigation of the Vasculature in Uppsala Seniors (PIVUS; women 50%, n=931; mean age, 70 years; median follow-up, 7.9 years) and the Uppsala Longitudinal Study of Adult Men (ULSAM; n=748; mean age, 77 years; median follow-up, 9.7 years). During follow-up, 90 participants died in PIVUS (1.28/100 person-years at risk), and 417 participants died in ULSAM (6.7/100 person-years at risk). In multivariable Cox regression models adjusted for age and established cardiovascular risk factors, 1 SD higher ln(serum endostatin level) was associated with a hazard ratio of mortality of 1.39 and 95% confidence interval, 1.26 to 1.53, on average in both cohorts. In the ULSAM cohort, serum endostatin was also associated with cardiovascular mortality (177 deaths; hazard ratio per SD of ln[endostatin] 1.45, 95% confidence interval [1.25-1.71]) and cancer mortality (115 deaths; hazard ratio per SD of ln[endostatin] 1.35, 95% confidence interval [1.10-1.66]). Conclusions High serum endostatin was associated with increased mortality risk in 2 independent community-based cohorts of the elderly. Our observational data support the importance of extracellular matrix remodeling in the underlying pathophysiology of cardiovascular disease and cancer.

- Leukemic cells from 85 children with newly diagnosed precursor B-lineage ALL were tested for in vitro drug sensitivity to a panel of anti-cancer drugs. Minimal residual disease (MRD) was measured by RQ-PCR. There was a significant correlation between MRD day 29 and in vitro sensitivity to prednisolone (p<0.001) and doxorubicin (p=0.017), drugs administered during induction therapy. In patients with t(12;21) (n=20), in vitro sensitivity to doxorubicin was an independent factor for MRD <0.1% (p=0.031; R(2)=0.66). Thus, data show that in vitro drug sensitivity at diagnosis is correlated to cell kill during induction therapy as measured by MRD day 29.

- The tumor cells in diffuse large B-cell lymphomas (DLBCL) are considered to originate from germinal center derived B-cells (GCB) or activated B-cells (ABC). Gene expression profiling (GEP) is preferably used to determine the cell of origin (COO). However, GEP is not widely applied in clinical practice and consequently, several algorithms based on immunohistochemistry (IHC) have been developed. Our aim was to evaluate the concordance of COO assignment between the Lymph2Cx GEP assay and the IHC-based Hans algorithm, to decide which model is the best survival predictor. Both GEP and IHC were performed in 359 homogenously treated Swedish and Danish DLBCL patients, in a retrospective multicenter cohort. The overall concordance between GEP and IHC algorithm was 72%; GEP classified 85% of cases assigned as GCB by IHC, as GCB, while 58% classified as non-GCB by IHC, were categorized as ABC by GEP. There were significant survival differences (overall survival and progression-free survival) if cases were classified by GEP, whereas if cases were categorized by IHC only progression-free survival differed significantly. Importantly, patients assigned as non-GCB/ABC both by IHC and GEP had the worst prognosis, which was also significant in multivariate analyses. Double expression of MYC and BCL2 was more common in ABC cases and was associated with a dismal outcome. In conclusion, to determine COO both by IHC and GEP is the strongest outcome predictor to identify DLBCL patients with the worst outcome.

- Between 1992 and 2008, 713 high hyperdiploid acute lymphoblastic leukemias in children aged 1-15 years were diagnosed and treated according to the Nordic Society for Pediatric Hematology and Oncology acute lymphoblastic leukemia 1992/2000 protocols. Twenty (2.8%) harbored t(1;19), t(9;22), der(11q23), or t(12;21). The median age was lower in the patients with 'classic' high hyperdiploidy than in those with translocation-positive high hyperdiploidy (P<0.001). Cases with triple trisomies (+4, +10, +17), comprising 50%, had higher modal numbers than the triple trisomy-negative cases (P<0.0001). The probabilities of event-free survival and overall survival were lower for those with white blood cell counts ≥50 x 109/L (P=0.017/P=0.009), ≥5% bone marrow blasts at day 29 (P=0.001/0.002), and for high risk patients (P<0.001/P=0.003), whereas event-free, but not overall, survival, was higher for cases with gains of chromosomes 4 (P<0.0001), 6 (P<0.003), 17 (P=0.010), 18 (P=0.049), and 22 (P=0.040), triple trisomies (P=0.002), and modal numbers >53/55 (P=0.020/0.024). In multivariate analyses, modal number and triple trisomies were significantly associated with superior event-free survival in separate analyses with age and white blood cell counts. When including both modal numbers and triple trisomies, only low white blood cell counts were significantly associated with superior event-free survival (P=0.009). We conclude that high modal chromosome numbers and triple trisomies are highly correlated prognostic factors and that these two parameters identify the same patient subgroup characterized by a particularly favorable outcome.

- Introduction: Warfarin treatment discontinuation is significant among patients with atrial fibrillation (AF). For AF patients with stroke a warfarin persistence rate of 0.45 after 2 years has previously been reported. No consistent predictors for discontinuation have been established. Aims: Evaluation of warfarin persistence and variables associated with discontinuation, in a large Swedish cohort with unselected stroke/TIA patients with AF treated with warfarin. Materials and methods: 4 583 patients with stroke/TIA and AF in the Swedish National Patient Register (NPR), from 1. Jan 2006 to 31. Dec 2011, were matched with the Swedish national quality register AuriculA. They were followed until treatment cessation, death or end of study. Baseline characteristics and CHA(2)DS(2)VASc score were retrieved from NPR. Treatment-time was retrieved from AuriculA. Results: Overall proportion of warfarin persistence was 0.78 (95% confidence interval (CI) 0.76 to 0.80) after one year, 0.69 (95% CI 0.67 to 0.71) after 2 years and 0.47 (95% CI 0.43 to 0.51) after 5 years. Variables clearly associated with higher discontinuation were dementia (hazard ratio (HR) 2.22, CI 1.51-3.27) and alcohol abuse (HR 1.66, CI 1.19-2.33). Chronic obstructive pulmonary disease (COPD), cancer and chronic heart failure (CHF) were each associated with over 20% increased risk of treatment discontinuation. Higher CHA(2)DS(2)VASc score and start-age lead to lower persistence (p < 0.001). Conclusions: Persistence to warfarin in unselected stroke/TIA patients with AF is in Sweden greater than previously reported. Lower persistence is found among patients with high treatment start-age, incidence of dementia, alcohol abuse, cancer, CHF, COPD and/or high CHA(2)DS(2)VASc score.

- The influence of estrogen signaling on infectious diseases is not fully known. Males seem to be more susceptible to infections than females. This has also been noted for the Scandinavian form of hemorrhagic fever with renal syndrome caused by Puumala hantavirus (PUUV). To investigate the differences in estrogen receptors in relation to sex and clinical severity, 20 patients (10 males, 10 females) with confirmed PUUV infection were studied. Real-time polymerase chain reaction was performed for analyzing mRNA expression of estrogen receptor-alpha (ERV), ER beta, and ER beta 2 (ER beta cx) in peripheral blood mononuclear cells from patients and healthy age-and sex-matched blood donors. Blood chemistry and peripheral blood mononuclear cells sampling were performed during the acute and convalescent phases. None or very small amounts of ER beta were detected, and ER alpha and ER beta 2 mRNA were elevated in the patient group. The samples from the males were correlated with ER beta 2; the female samples, with ER alpha. Furthermore, the female and male samples are partly separated using multivariate statistic analysis (principal component analysis), supporting findings that clinical symptoms differ depending on sex.
