Schizophrenia (SCZ), bipolar (BD) and major depression disorder (MDD) are severe psychiatric disorders that are challenging to treat, often leading to treatment resistance (TR). It is crucial to develop effective methods to identify and treat patients at risk of TR at an early stage in a personalized manner, considering their biological basis, their clinical and psychosocial characteristics. Effective translation of theoretical knowledge into clinical practice is essential for achieving this goal.

Article Synopsis
  • The study examined how positive, negative, and disorganized psychotic symptom dimensions relate to different clinical and developmental variables, addressing inconsistencies in definition and prior research.
  • Results showed that higher symptom scores were linked to poor social adjustment, earlier onset of symptoms, and specific demographic factors, such as ethnicity and gender.
  • The findings also suggested a significant familial influence on disorganized symptoms, highlighting the connections between these symptoms and lower premorbid IQ, especially within monozygotic twin pairs.

Current solutions to global challenges place tension between global benefits and local impacts. The result is increasing opposition to implementation of beneficial climate policies. Prioritizing investment in projects with tangible local benefits that also contribute to global climate change can resolve this tension and make local communities' partners instead of antagonists to change; the approach advocated is a new take on "thinking globally, acting locally".

Article Synopsis
  • - Bile acid diarrhea is often misdiagnosed and can stem from primary, idiopathic conditions like functional diarrhea or secondary issues such as ileal resection or post-cholecystectomy complications, highlighting a need for improved diagnostic strategies.
  • - Management typically focuses on long-term symptom relief with bile acid sequestrants being the primary treatment, though questions remain regarding their optimal use; newer options like GLP-1 receptor agonists show promise but are more expensive and less available.
  • - There is a call for more research into the underlying causes and treatments for bile acid diarrhea, as well as a better understanding of dietary impacts on symptoms, to enhance patient care.

Purpose: The purpose of this review is to discuss the role of toxin inhibition in select infections and to provide recommendations for appropriate antimicrobial selection when toxin inhibition is indicated.

Summary: For select organisms, specifically Clostridioides difficile, Staphylococcus aureus, and Streptococcus pyogenes, toxin production plays an integral role in overall disease pathogenesis and progression. Some expert recommendations include utilization of an antimicrobial with toxin inhibition properties as primary or adjunctive therapy for certain infections due to these organisms, but evolving data have made the choice of antitoxin agent less clear.

STriatal-Enriched protein tyrosine Phosphatase (STEP) is a brain-specific tyrosine phosphatase that is associated with numerous neurological and neuropsychiatric disorders. STEP dephosphorylates and inactivates various kinases and phosphatases critical for neuronal function and health including Fyn, Pyk2, ERK1/2, p38, and PTPα. Importantly, STEP dephosphorylates NMDA and AMPA receptors, two major glutamate receptors that mediate fast excitatory synaptic transmission.

Background: The ganglionic eminences (GE) are fetal-specific structures that give rise to gamma-aminobutyric acid (GABA)- and acetylcholine-releasing neurons of the forebrain. Given the evidence for GABAergic, cholinergic, and neurodevelopmental disturbances in schizophrenia, we tested the potential involvement of GE neuron development in mediating genetic risk for the condition.

Study Design: We combined data from a recent large-scale genome-wide association study of schizophrenia with single-cell RNA sequencing data from the human GE to test the enrichment of schizophrenia risk variation in genes with high expression specificity for developing GE cell populations.
