- Genetic associations for the reoccurrence of venous thromboembolism (VTE) are not well described. Our aim was to investigate if common genetic variants, previously found to contribute to the prediction of first time thrombosis in women, were associated with risk of recurrence. The Thromboembolism Hormone Study (TEHS) is a Swedish nationwide case-control study (2002-2009). A cohort of 1,010 women with first time VTE was followed up until a recurrent event, death or November 2011. The genetic variants in F5 rs6025, F2 rs1799963, ABO rs514659, FGG rs2066865, F11 rs2289252, PROC rs1799810 and KNG1 rs710446 were assessed together with clinical variables. Recurrence rate was calculated as the number of events over the accumulated patient-time. Cumulative recurrence was calculated by Kaplan-Meier curve. Cox proportional-hazard model was used to estimate hazard ratios (HR) and 95 % confidence intervals (95 % CI) between groups. A total of 101 recurrent events occurred during a mean follow-up time of five years. The overall recurrence rate was 20 per 1,000 person-years (95 % CI; 16-24). The recurrence rate was highest in women with unprovoked first event and obesity. Carriers of the risk alleles of F5 rs6025 (HR=1.7 (95 % CI; 1.1-2.6)) and F11 rs2289252 (HR=1.8 (95 % CI; 1.1-3.0)) had significantly higher rates of recurrence compared to non-carriers. The cumulative recurrence was 2.5-fold larger in carriers of both F5 rs6025 and F11 rs2289252 than in non-carriers at five years follow-up. In conclusion, F5 rs6025 and F11 rs2289252 contributed to the risk of recurrent VTE and the combination is of potential clinical relevance for risk prediction.

- PurposeThis study aimed to investigate various aspects of treatment for retinopathy of prematurity (ROP) in Sweden over the past 14 years, nationally and at a hospital level.MethodsData on screening and treatment for ROP in infants born in Sweden from 2008 to 2021 were extracted from the national ROP register, SWEDROP. During this period, Swedish screening guidelines were reduced from gestational age (GA) < 32 weeks to <31 weeks in 2012 and to <30 weeks in 2020.ResultsAltogether, 10 959 infants were screened and 600 infants treated for ROP during the study period. Parallel to changed guidelines, the number of screened infants decreased (p < 0.000) and the incidence of ROP and frequency of treatment increased (p < 0.001), while both remained similar in infants with a GA below 30 weeks. Among treated infants, GA and BW were reduced over the years (p < 0.001). Laser treatment (85.2% of primary treatments) became less common and anti-VEGF injections (13.6%) became more common over time (p < 0.001). Altogether 16 eyes were treated with the encircling band and 13 with vitrectomy. The total frequency of retreatment (32.7% of treated eyes) remained similar over time but was more common after primary anti-VEGF injection (67.7%) than laser treatment (27.2%). There were differences between the seven university hospitals regarding type of treatment and number of retreatments (p < 0.001).ConclusionThe frequency of treatment and retreatment for ROP remained similar over time, but the type of treatment changed and anti-VEGF injections became more common. Differences between treating hospitals emphasize the importance of centralizing the most severe cases.

- Background: Patients with a history of venous thromboembolism (VTE) seem to have an increased risk of arterial cardiovascular disease (CVD). Objectives: To evaluate the risk of CVD and overall mortality after a first episode of VTE in women and to assess common risk factors for VTE and CVD. Patients/methods: We performed a cohort study inviting 1433 women with a previous VTE (exposed) and 1402 women without VTE (unexposed). The cohort was derived from TEHS, a Swedish population-based case-control study on risk factors for VTE in women age 18-64 years. The women were recruited in 2002-2009. During 2011 information on CVD and mortality was obtained from a questionnaire and from the Swedish Patient Register and the Cause of Death Register. Hazard ratios (HR) for CVD and their 95% confidence intervals (CI) were calculated using Cox regression. In multivariate analyses we adjusted for age, smoking, diabetes mellitus, hypertension and body mass index. Results: 2108 (75%) women (mean age 47 +/- 13 years) accepted participation. During the total follow up of 11,920 person years 35 (3.2%, 95% CI 0.7-2.1) among the exposed and 14 (1.4%, 95% CI 0.2-4.3) among the unexposed had any CVD event. The adjusted HR for CVD was 2.0 (95% CI 1.1-3.9) the adjusted HR for mortality was 2.3 (95% CI 1.2-4.6) Conclusion: Women with a previous VTE had a two-fold increased risk of CVD and overall mortality. Adjusting for cardiovascular risk factors only modestly changed the estimates.
