Background. T-cell lymphoblastic lymphoma (T-LBL) is a rare neoplasm of precursor lymphoblast origin, for which there is no standard treatment for adults. Results of current treatment strategies in selected populations do exist but are largely unreported for unselected series. Here, we aimed to investigate treatment outcome in a population-based cohort. Material and methods. Patients were identified through the Swedish Lymphoma Registry and data was retrospectively collected for all adult (≥ 18 years) Swedish T-LBL patients diagnosed during 2000-2009. Results. A total of 39 patients with median age 40 years (range 18-78) were identified with females being significantly older than males (median age 66 vs. 37, p = 0.027). The five-year overall survival for all patients was 42%. Female gender was associated with shorter survival also when adjusted for treatment strategy and age [hazard ratio (HR) 4.29; p = 0.002]. Thirty patients received intensive chemotherapy, otherwise used for treatment of acute lymphoblastic leukemia (ALL), which resulted in an overall response rate of 97% and a five-year progression-free survival (PFS) of 49%. In this group only CNS involvement at diagnosis predicted shorter PFS (HR 13.3; p = 0.03). Among patients treated with hyper-CVAD the addition of mediastinal irradiation resulted in prolonged time to progression compared to patients receiving only chemotherapy (p = 0.047). The major reason for treatment failure was relapse and in this series 18-fluoro-deoxyglucose positron emission tomography (PET) did not predict this risk. Conclusion. This population-based study indicates that all fit T-LBL patients should be considered for intensive treatment. Our results also suggest a beneficial effect of mediastinal irradiation in combination with hyper-CVAD treatment. Relapsing patients have a dismal outcome irrespective of salvage treatment. © 2014 Informa Healthcare. Source

OBJECTIVE: The goal was to examine whether parent-reported infection at the time of gluten introduction increases the risk of future celiac disease (CD). METHODS: Through the population-based All Infants in Southeast Sweden study, parents recorded data on feeding and infectious disease prospectively. Complete data on gluten introduction and breastfeeding duration were available for 9408 children. Those children had 42 826 parent-reported episodes of infectious disease in the first year of life (including 4003 episodes of gastroenteritis). We identified 44 children with biopsy-verified CD diagnosed after 1 year of age, and we used Cox regression to estimate the risk of future CD for children with infection at gluten introduction. RESULTS: Eighteen children with CD (40.9%) had an infection at the time of gluten introduction, compared with 2510 reference individuals (26.8%; P = .035). Few children had gastroenteritis at the time of gluten introduction (1 child with CD [2.3%] vs 166 reference individuals [1.8%]; P = .546). With adjustment for age at gluten introduction and breastfeeding duration, we found no association between a future diagnosis of CD and either any infection (adjusted hazard ratio: 1.8 [95% confidence interval: 0.9 -3.6]) or gastroenteritis (adjusted hazard ratio: 2.6 [95% confidence interval: 0.2-30.8]) at the time of gluten introduction. We found no associations between breastfeeding duration, age at gluten introduction, and future CD. CONCLUSION: These results indicate that parent-reported infection at the time of gluten introduction is not a major risk factor for CD. Copyright © 2010 by the American Academy of Pediatrics. Source

Objectives: The purpose of this study was to determine whether statin treatment is effective and safe in very elderly (80 years and older) acute myocardial infarction (AMI) patients. Background: Elderly individuals constitute an increasing percentage of patients admitted to hospitals for AMI. Despite that these patients have a higher mortality risk, the application of evidence-based medicine remains much lower than for younger patients. Methods: We included all patients 80 years and older who were admitted with the diagnosis of AMI in the Register of Information and Knowledge About Swedish Heart Intensive Care Admissions between 1999 and 2003 (n = 21,410). Of these, complete covariate and follow-up data were available for 14,907 patients (study population A). To limit the bias related comorbidity on statin therapy, we also performed analyses excluding patients who died within 14 days of the acute event (study population B) and all patients who died within 365 days (study population C). A propensity score was used to adjust for initial differences between treatment groups. Results: All-cause mortality was significantly lower in patients receiving statin treatment at discharge in study population A (relative risk: 0.55, 95% confidence interval: 0.51 to 0.59), in study population B (relative risk: 0.65; 95% confidence interval: 0.60 to 0.71), and in study population C (relative risk: 0.66; 95% confidence interval: 0.59 to 0.76). Similar observations were made for cardiovascular mortality as well as for AMI mortality. There was no increase in cancer mortality in statin-treated patients. Conclusions: Statin treatment is associated with lower cardiovascular mortality in very elderly post-infarction patients without increasing the risk of the development of cancer. © 2010 American College of Cardiology Foundation.

Peripheral T-cell lymphomas (PTCLs) are rare lymphomas with mostly poor outcome with current treatment. The addition of etoposide to cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) and upfront consolidation with autologous stem cell transplantation (auto-SCT) have shown promising results but have never been tested in randomized trials. As a complement to retrospective analyses of clinical trials, we aimed at analyzing prognostic factors and outcome in an unselected, population-based cohort. Through the Swedish Lymphoma Registry, we identified 755 PTCL patients diagnosed during a 10-year period. In addition to International Prognostic Index factors, male gender was associated with an adverse overall survival (OS) (hazard ratio [HR], 1.28; P = .011) and progression-free survival (PFS) (HR, 1.26; P = .014). In an intention-to-treat analysis in 252 nodal PTCL and enteropathy-associated T-cell lymphoma patients (excluding anaplastic lymphoma kinase-positive anaplastic large cell lymphoma), upfront auto-SCT was associated with a superior OS (HR, 0.58; P = .004) and PFS (HR, 0.56; P = .002) compared with patients treated without auto-SCT. The addition of etoposide to CHOP resulted in superior PFS in patients ≤60 years (HR, 0.49; P = .008). This study is the largest population-based PTCL cohort reported so far and provides important information on outcome in PTCL outside the setting of clinical trials. © 2014 by The American Society of Hematology.

Background. Studies of antibiotic prescribing related to diagnosis comparing prescribers trained abroad with those trained in Sweden are lacking. Objectives. To determine whether general practices (GPs) and GP residents trained abroad had different prescribing patterns for antibiotics for common infections than those trained in Sweden using retrospective data from electronic patient records from primary health care in Kalmar County, Sweden. Methods. Consultations with an infection diagnosis, both with and without the prescription of antibiotics to 67 GPs and residents trained in Western Europe outside Sweden and other countries, were compared with a matched control group trained in Sweden. Results. For 1 year, 44 101 consultations of patients with an infection diagnosis and 16 276 prescriptions of antibiotics were registered. Foreign-trained physicians had 20% more visits compared with physicians trained in Sweden. The prescription of antibiotics per visit and physician in the respective groups, and independent of diagnosis, did not significantly differ between groups, when scaled down from number of consultations to number of prescribing physicians. Conclusions. There were minor and non-significant differences in antibiotic prescribing comparing GPs and residents trained abroad and in Sweden, most likely the result of an adaptation to Swedish conditions. Nevertheless, no group prescribed antibiotics in accordance to national guidelines. The results suggest that interventions are needed to reduce irrational antibiotic prescribing patterns, targeting all physicians working in Swedish primary health care. © The Author 2015.
