Psychiatric disorders are often associated with metabolic comorbidities. However, the mechanisms through which metabolic and psychiatric disorders are connected remain unclear. Pre-clinical studies in rodents indicate that the bidirectional signaling between the intestine and the brain, the so-called microbiome-gut-brain axis, plays an important role in the regulation of both metabolism and behavior. The gut microbiome produces a vast number of metabolites that may be transported into the host and play a part in homeostatic control of metabolism as well as brain function. In addition to short chain fatty acids, many of these metabolites have been identified in recent years. To what extent both microbiota and their products control human metabolism and behavior is a subject of intense investigation. In this review, we will discuss the most recent findings concerning alterations in the gut microbiota as a possible pathophysiological factor for the co-occurrence of metabolic comorbidities in psychiatric disorders.

Background: Mental illness is one of the top causes of preventable pregnancy-related deaths in the United States. There are many barriers that interfere with the ability of perinatal individuals to access traditional mental health care. Digital health interventions, including app-based programs, have the potential to increase access to useful tools for these individuals.

Background: Scientific implementation findings relevant to the implementation of internet-delivered cognitive behavioral therapy (iCBT) for depression and anxiety in adults remain sparse and scattered across different sources of published information. Identifying evidence-based factors that influence the implementation of iCBT is key to successfully using iCBT in real-world clinical settings.
Objective: This systematic review evaluated the following: (1) aspects that research articles postulate as important for the implementation of iCBT and (2) aspects relevant to the day-to-day running of iCBT services.
Pre-treatment subjective sleep quality as a predictive biomarker of tDCS effects in preclinical Alzheimer's disease patients: Secondary analysis of a randomised clinical trial.

Department of Psychiatry, The Chinese University of Hong Kong, Sha Tin, Hong Kong SAR, China.
Background: Despite transcranial direct current stimulation (tDCS) has demonstrated encouraging potential for modulating the circadian rhythm, little is known about how well and sustainably tDCS might improve the subjective sleep quality in older adults. This study sought to determine how tDCS affected sleep quality and cognition, as well as how well pre-treatment sleep quality predicted tDCS effects on domain-specific cognitive functions in patients with mild neurocognitive disorder due to Alzheimer's disease (NCD-AD).
Methods: This clinical trial aimed to compare the effectiveness of tDCS and cognitive training in mild NCD-AD patients (n = 201).
Objective: Aim: To investigate the etiology, pathogenesis, and effectiveness of pharmacotherapy and psychotherapeutic modalities of delusions in Schizophrenia spectrum and other Psychotic Disorders.
Patients And Methods: Materials and Methods: In our study, we included English-language studies from online databases such as Web of Science, Scopus, Google Scholar, PubMed, and the Cochrane Library conducted until January 2024 using the following keywords "delusions", "Schizophrenia spectrum and other Psychotic Disorders", "pharmacotherapy", "psychotherapy", and "antipsychotics". Scientific novelty: There is already published evidence that has studied Schizophrenia spectrum disorders from definition to treatment.
Objective: Aim: The aim is to investigate the causes of stress and its impact on women's mental and physical health indicators.
Patients And Methods: Materials and Methods: The research was conducted from 2022 to 2024 and involved 157 women from Zhytomyr oblast (Ukraine) of different ages, education, professions, and geographic residence. The research methods included analysis of literary sources, medical and sociological (survey), statistical method.
