Impact of multiple traumatic experiences on the persistence of depressive symptoms – a population-based study

The objective of this population-based study was to determine whether traumatic experiences in general, and multiple traumatic experiences in particular, are associated with persistent self-rated depressive symptoms in adult Finnish subjects over 2?years of follow-up. The study sample included 1405 subjects aged 25–64?years. Subjects (n=217) who were depressed both at baseline in 1999 and on follow-up 2?years later in 2001 (having persistent depressive symptoms) were compared with subjects (n=987) having no depressive symptoms either at baseline or on follow-up. All six categories of traumatic experiences (wartime experience, natural disaster, life-threatening accident, victim of violent crime, domestic violence and childhood sexual abuse) pertained to the respondents’ whole life span. Odds ratios, adjusted for significant covariates, were obtained from multiple logistic regression models that estimated the likelihood of persistent depressive symptoms in different trauma categories. Persistent depressive symptoms had a significant positive graded relationship with the number of traumatic experiences. The adjusted odds of persistent depression was 6.05 (95% CI 1.76–20.7) for men and 6.99 (95% CI 2.69–18.2) for women in those with three or more traumatic experiences compared with those with no such experiences at all. Multiple traumatic experiences substantially increase the likelihood of persistent depressive symptoms. Mental health intervention, as early as possible, may serve to prevent the chronicity of depressive reactions among victims of multiple traumas.     

Total Knee Arthroplasty with an Uncemented Trabecular Metal Tibial Component : A Registry-Based Analysis

Previous poor results have kept the appeal of uncemented total knee arthroplasties (TKAs) minimal. We analyzed the mid-term survivorship and reasons for failures of a contemporary uncemented porous tantalum monoblock tibial component nation-wide. During the study period (2003–2010), such tibial components were used in 1143 primary TKAs recorded in the Finnish Arthroplasty Registry. Seven-year survivorship of these TKAs was 100% (95% CI 99–100) with revision for aseptic loosening of the tibial component, and 97% (95% CI 96–98) with revision for any reason as the respective end points. The most common reasons for revisions were instability and prosthetic joint infections. In conclusion, TKAs using an uncemented porous tantalum monoblock tibial component showed excellent mid-term survivorship in a population-based setting.     

Long‐term outcome of intraventricular conduction delays in the general population

BackgroundPrevious population studies have presented conflicting results regarding the prognostic impact of intraventricular conduction delays (IVCD).MethodsWe studied long‐term prognostic impact and the association with comorbidities of eight IVCDs in a random sample of 6,299 Finnish subjects (2,857 men and 3,442 women, mean age 52.8, SD 14.9 years) aged 30 or over who participated in the health examination including 12‐lead ECG. For left bundle branch block (LBBB) and non‐specific IVCD (NSIVCD), two different definitions were used.ResultsDuring 16.5 years’ follow‐up, 1,309 of the 6,299 subjects (20.8%) died and of these 655 (10.4%) were cardiovascular (CV) deaths. After controlling for known clinical risk factors, the hazard ratio for CV death, compared with individuals without IVCD, was 1.55 for the Minnesota definition of LBBB (95% confidence interval 1.04–2.31, p = .032) and 1.27 (95% confidence interval 0.80–2.02, p = .308) for the Strauss’ definition of LBBB. Subjects with NSIVCD were associated with twofold to threefold increase in CV mortality depending on the definition. While right bundle branch block, left anterior fascicular block and incomplete bundle branch blocks were associated with seemingly higher mortality, this was no longer the case after adjustment for age and sex. The presence of R‐R’ pattern was not associated with any adverse outcome.ConclusionsIn a population study with long‐term follow‐up, NSIVCD and Minnesota definition of LBBB were independently associated with CV mortality. Other IVCDs had no significant impact on prognosis. The prognostic impact of LBBB and NSIVCD was affected by the definition of the conduction disorder.
