Adherence to the Mediterranean dietary pattern and incidence of anorexia and bulimia nervosa in women: The SUN cohort.

Objective: To our knowledge, no study has yet assessed the association between dietary patterns and incidence of eating disorders. This study aimed to assess the association between adherence to the Mediterranean dietary pattern (MDP) and incident risk of anorexia (AN) and bulimia nervosa (BN).

Methods: We conducted a prospective cohort study of 11 800 women from the Seguimiento Universidad de Navarra follow-up project.

Impact of COMT genotype on cognition in schizophrenia spectrum patients and their relatives.

Cognitive impairment in schizophrenia is a core feature and seems to be related mainly to dopaminergic dysfunction in the prefrontal cortex (PFC). The functional polymorphism Val158Met of the COMT (catechol-O-methyltransferase) gene could mediate the relationship between cognition and dopamine activity in PFC. The present study tested the influence of this polymorphism on the cognitive performance of schizophrenia spectrum patients and their relatives, using some subtests of the neuropsychological battery, the Measurement and Treatment Research to Improve Cognition in Schizophrenia (MATRICS) Consensus Cognitive Battery, and evaluated the impact of this polymorphism on a specific prefrontal cognitive function using a cognitive neuroscience paradigm.
