Aim: To analyze the clinical, neurocognitive, and functional impact of prolactin levels according to sex in patients with a First Episode Psychosis (FEP).
Methods: We measured prolactin levels in 221 non-affective FEP patients treated with antipsychotics (AP) and 224 healthy controls, at baseline and 2-year follow-up. We examined whether the relationships between clinical and functional variables were mediated by prolactin, controlling for antipsychotic use, according to sex.
Article Synopsis
- The study examined the relationship between hair cortisol concentration (HCC) and cognitive functioning in adolescents with ADHD, with a focus on how sex and childhood maltreatment might influence this association.
- Fifty-three adolescents with ADHD participated in the study, undergoing various assessments including cognitive tasks and psychological questionnaires to measure ADHD severity and trauma history.
- The findings indicated that higher HCCs were linked to better attention and memory performance, particularly in boys, while no significant connections were found between HCCs and executive functioning or general ADHD symptoms.
Background: Irritable bowel syndrome is a heterogeneous syndrome and it is difficult to find an effective treatment. Previously, a starch- and sucrose-reduced diet (SSRD) demonstrated promising short-term outcomes. It was proposed that genetic variants in the sucrose-isomaltase gene might influence this success.

Nutritional interventions have been proposed to alleviate symptoms, since still no effective treatments exist for IBS.
Objectives: Our aim is to analyse the feasibility of the use of starch- and sucrose-reduced diet (SSRD).
Background: Previous data support that the inflammatory process underlying ulcerative colitis (UC) and Crohn's disease (CD) can start years before the diagnosis. The aim of this study was to determine if patients with an incidental diagnosis of UC or CD demonstrate an increase in healthcare utilization in the years preceding the symptomatic onset of the disease.
Methods: We performed a multicenter, retrospective, hospital-based, case-control study.
