Alterations of the IKZF1-IKZF2 tandem in immune cells of schizophrenia patients regulate associated phenotypes.

Schizophrenia is a complex multifactorial disorder and increasing evidence suggests the involvement of immune dysregulations in its pathogenesis. We observed that IKZF1 and IKZF2, classic immune-related transcription factors (TFs), were both downregulated in patients' peripheral blood mononuclear cells (PBMCs) but not in their brain. We generated a new mutant mouse model with a reduction in Ikzf1 and Ikzf2 to study the impact of those changes.

Intestinal permeability biomarkers in patients with schizophrenia: Additional support for the impact of lifestyle habits.

Background: Emerging evidence suggests a potential association between "leaky gut syndrome" and low-grade systemic inflammation in individuals with psychiatric disorders, such as schizophrenia. Gut dysbiosis could increase intestinal permeability, allowing the passage of toxins and bacteria into the systemic circulation, subsequently triggering immune-reactive responses. This study delves into understanding the relationship between plasma markers of intestinal permeability and symptom severity in schizophrenia.

Pre- and post-COVID 19 outbreak relationship between physical activity and depressive symptoms in Spanish adults with major depressive disorder: a secondary analysis of the RADAR-MDD cohort study.

Aim: To evaluate the longitudinal association of sedentary behavior, light and moderate-to-vigorous physical activity (MVPA) participation with depressive symptoms and whether their possible association changed depending on the pandemic phase.

Methods: This longitudinal study conducted secondary analysis from the Spanish cohort of the Remote Assessment of Disease and Relapse - Major Depressive Disorder (RADAR-MDD) study. Depressive symptoms were assessed by the Patient Health Questionnaire (PHQ-8).

Relationship Between Exposure to Emotional Neglect and the Inflammatory Biomarkers Neutrophil-to-Lymphocyte, Monocyte-to-Lymphocyte, and Platelet-to-Lymphocyte Ratios in Patients With First-Episode Psychosis.

To assess whether exposure to childhood traumatic experiences is linked to the inflammatory markers neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), and platelet-to-lymphocyte ratio (PLR) in people with a first-episode psychosis. A cross-sectional study was performed in 83 patients (21 females and 62 males) with a diagnosis of a first psychotic episode. All participants completed the self-reported Spanish version of the Childhood Trauma Questionnaire (CTQ).

Maternity in women with schizophrenia and schizoaffective disorder.

Purpose: Maternity rates in women with schizophrenia have tripled in the past decades, with a current percentage similar to the general population (50-60%). However, mothers with schizophrenia present higher rates of single marital status, and social dysfunction than the general population. In addition, the incidence of unplanned pregnancy, abortions, miscarriages and obstetric complications is higher.
