[Description of trajectories of patients with end-stage renal disease from the REIN registry]

CONTEXT AND OBJECTIVES

Since 2001, the aim of the REIN registry has been to identify patients suffering from end-stage renal disease and benefiting from replacement therapy in France. The analysis of trajectories aims to evaluate the flow of patients between the different types of treatment in order to better understand and predict patient pathways. The objective of this study was to analyse the incoming and outgoing flows at 1 year of patients prevalent in the REIN registry on 12/31/2017.

METHODS

Flow analysis was carried out on patients prevalent on 12/31/2017 in the REIN registry by studying the before and after treatment modalities on 12/31/2016 and 12/31/2018. This analysis was initially carried out on all patients, then in sub-groups for each of the 5 treatment modalities.

RESULTS

The analyses covered 85,472 patients prevalent on 12/31/2017. The overall analysis showed that more than 20% of patients had been diagnosed with end-stage renal disease the year before. Regarding inflow, there was a relative stability for patients treated with self-care hemodialysis, in-center haemodialysis, peritoneal dialysis, and graft, in contrast to patients treated with hemodialysis in a medical unit. Regarding outgoing flows, proportion of deaths at one year was 9%. Peritoneal dialysis was the modality with the highest outflow proportion at one year.

CONCLUSION

Analysis of patients' trajectories shows variable evolution profiles according to treatment modality and thus could be a valuable tool in the evaluation and improvement of management and care in the field of end-stage renal disease.

[The schizophrenic's chilhood]

Pathology of adolescence and young adult, schizophrenia can begin in very rare cases during childhood. Two early clinical forms of the disorder have been identified by epidemiological studies: one beginning at the age of 15; the other around 9 years old; While many questions remain unsanswered about the neurobiological and environmental factors - common or distinct - of these two clinical phenotype, both are related to a profoun and lasting alteration of the neurocognitive development whose origin would clearly go back to infancy or to the antenal period. Here we will present a possible story back of schizophrenia in the light of the latest neuroscientific studies in imagery and genetics from adolescence to antenal period.
