Article Synopsis
  • The study investigates the geographical variation in the prevalence of multiple sclerosis (MS) across 21 departments in France to improve healthcare provision.
  • Using a spatial Bayesian approach and various data sources, the prevalence of MS was found to significantly differ between regions, with the northeast showing the highest rates.
  • The research highlights the complexity of MS prevalence variation, suggesting factors like migration, socioeconomic status, and environmental influences may play a role, without clear ties to healthcare access or facilities.

Few studies have addressed longer-term survival for breast cancer in European women. We have made predictions of 10-year survival for European women diagnosed with breast cancer in 2000-2002. Data for 114,312 adult women (15-99 years) diagnosed with a first primary malignant cancer of the breast during 2000-2002 were collected in the EUROCARE-4 study from 24 population-based cancer registries in 14 European countries.

Introduction: This study aimed at modelling the effect of organized breast cancer screening on mortality in France. It combined results from a Markov model for breast cancer progression, to predict number of cases by node status, and from relative survival analyses, to predict deaths. The method estimated the relative risk of mortality at 8 years, in women aged 50-69, between a population screened every two years and a reference population.

On a population-based sample of 13,500 European breast cancer patients mostly diagnosed in 1996-1998 and archived by 26 cancer registries, we used logistic regression to estimate odds of conservative surgery plus radiotherapy (BCS+RT) versus other surgery, in T1N0M0 cases by country, adjusted for age and tumour size. We also examined: BCS+RT in relation to total national expenditure on health (TNEH); chemotherapy use in N+ patients; tamoxifen use in oestrogen-positive patients; and whether 10 nodes were examined in lymphadenectomies. Stage, diagnostic examinations and treatments were obtained from clinical records.

The reminiscence bump corresponds to a marked increase in autobiographical memories of events that occurred when normal people were aged 10 to 30 years, a critical period for the formation of identity. The reminiscence bump was studied in 27 patients diagnosed with schizophrenia and 27 control participants. They were asked to recall 20 specific autobiographical events that had occurred during their lifetime and to indicate the subjective states of awareness associated with the recalled memories using the Remember/Know procedure.

Article Synopsis
  • Effective treatments for testicular cancer have been available since the 1970s, but significant differences in survival rates were found across nine European countries according to the EUROCARE study.
  • The study analyzed clinical records of 1,350 cases diagnosed from 1987 to 1992, revealing that ten-year survival rates varied widely, from 63% in Estonia to 94% in Switzerland for seminomas, and 47% in Estonia to 90% in Yorkshire for non-seminomas.
  • Multivariable analyses indicated that survival differences were largely due to variations in stage at diagnosis, with higher death hazard ratios in countries like Estonia and Poland suggesting potential inadequacies in treatment availability.
