The October 7th, 2023, terror attacks in Israel were characterized by a scope and magnitude not previously known to Israeli citizens. The aim of this study was to examine the prevalence and correlates of posttraumatic stress disorder (PTSD), emotional distress and use of addictive substances among Israeli adults, approximately one month following the attacks. PTSD was assessed with the Posttraumatic Stress Disorder Checklist (PCL-5) and emotional distress was assessed with a brief version of the Hopkins Symptom Checklist (HSCL-25)...

To investigate the clinical application value of pharmacogenetic testing in individualized drug therapy for adult male patients with schizophrenia. A total of 186 adult patients with schizophrenia were enrolled and randomised into the pharmacogenetic (PGx) intervention group and the standard care group. In the PGx intervention group, PGx testing was performed, and the medication regimen was adjusted according to the results of the pharmacogenomic analysis. In contrast, in the standard care group, patients were treated according to the physician's medication experience...

Psychiatric disorders are associated with serve disturbances in cognition, emotional control, and/or behavior regulation, yet few routine clinical tools are available for the real-time evaluation and early-stage diagnosis of mental health. Abnormal levels of relevant biomarkers may imply biological, neurological, and developmental dysfunctions of psychiatric patients. Exploring biosensors that can provide rapid, in-situ, and real-time monitoring of psychiatric biomarkers is therefore vital for prevention, diagnosis, treatment, and prognosis of mental disorders...

IMPORTANCE: Although insomnia guidelines recommend the use of several individual hypnotics, the most useful hypnotic for treating insomnia in a clinical setting remains unclear. OBJECTIVE: To determine which guideline-recommended hypnotics have lower risks of monotherapy failure and which hypnotics have a higher risk of long-term prescription for insomnia treatment. DESIGN, SETTING, AND PARTICIPANTS: This retrospective observational cohort study used data from the Japan Medical Data Center Claims Database from April 1, 2005, to March 31, 2021...

Substance use disorders (SUDs) are the most costly and prevalent psychiatric conditions. Recent calls emphasize a need for biomarkers-measurable, stable indicators of normal and abnormal processes and response to treatment or environmental agents-and, in particular, brain-based neuromarkers that will advance understanding of the neurobiological basis of SUDs and clinical practice. To develop neuromarkers, researchers must be grounded in evidence that a putative marker (i) is sensitive and specific to the psychological phenomenon of interest, (ii) constitutes a predictive model, and (iii) generalizes to novel observations (e...

About 20% of adults experience excessive daytime sleepiness or severe fatigue. Causes include somatic conditions, psychiatric disorders, and medication or drug use. Treatment depends on the underlying cause. If sleepiness persists despite optimal treatment of the underlying condition, exclusion of other causes, and behavioral interventions, wakefulness-promoting agents may be considered. However, no established pharmacological strategy exists for symptomatic treatment. Modafinil and stimulants like methylphenidate may offer some benefit based on experiences with narcolepsy or idiopathic hypersomnia...

The central amygdaloid nucleus (CeA) has an ancient phylogenetic development and functions relevant for animal survival. Local cells receive intrinsic amygdaloidal information that codes emotional stimuli of fear, integrate them, and send cortical and subcortical output projections that prompt rapid visceral and social behavior responses. We aimed to describe the morphology of the neurons that compose the human CeA (N = 8 adult men). Cells within CeA coronal borders were identified using the thionine staining and were further analyzed using the "single-section" Golgi method followed by open-source software procedures for two-dimensional and three-dimensional image reconstructions...

WHAT IS KNOWN ON THE SUBJECT?: New parents who have previously experienced psychosis outside and/or following childbirth have an increased likelihood of experiencing an episode during the postpartum period. The decision to try to conceive can be agonising. Receiving care from a specialist perinatal community mental health team can improve outcomes. WHAT DOES THIS PAPER ADD TO EXISTING KNOWLEDGE?: This article offers a first-person insight into the steps the author took to minimise the impact of an episode of postpartum psychosis and/or postnatal depression whilst navigating new motherhood...

OBJECTIVE: Research on psychiatric comorbidities associated with avoidant/restrictive food intake disorder (ARFID) primarily compares ARFID versus anorexia nervosa (AN). Little is known about comorbidities associated with mixed ARFID/other eating disorder (ED) history or ARFID comorbidities relative to EDs beyond AN. This study assessed lifetime and current psychiatric factors in a large college sample with varying ED histories. METHOD: Participants were United States students from the 2021/2022 Healthy Minds Study who endorsed lifetime professionally diagnosed EDs (N = 4657)...

The human gut microbiome plays an important role in the maturation of the neural, immune, and endocrine systems. Research data from animal models shows that gut microbiota communicate with the host's brain in an elaborate network of signaling pathways, including the vagus nerve. Part of the microbiome's influence extends to the behavioral and social development of its host. As a social species, a human's ability to communicate with others is imperative to their survival and quality of life. Current research explores the gut microbiota's developmental influence as well as how these gut-brain pathways can be leveraged to alleviate the social symptoms associated with various neurodevelopmental and psychiatric diseases...

BACKGROUND: Sodium valproate (valproate) that is used both as an anti-epileptic and a mood stabiliser is teratogenic in pregnancy. A Dear Health Care Professional Letter (DHCPL) issued in December 2015 recommended the avoidance of sodium valproate prescription in women of childbearing age (WOCBA) and pregnant women. AIM: This study aimed to describe the prescription pattern of valproate in female mental healthcare users (MHCUs). SETTING: Regional hospital psychiatry department in King Dinizulu Hospital Complex, Durban, KwaZulu-Natal...

BACKGROUND: Women charged with violent offences may be referred by courts for forensic psychiatric assessment to determine whether mental disorder or intellectual disability impacts their fitness to stand trial and/or criminal responsibility. The profile of these women is a poorly researched area in South Africa. AIM: This study examined the socio-demographic, offence-related, and clinical profile of South African women charged with violent offences referred for forensic assessment...

BACKGROUND: Trauma experiences, particularly in childhood, have been associated with criminality and mental illness. There is a paucity of research into the crime of murder, trauma and mental illness. AIM: This research study focused on state patients charged with murder and sought to determine associations with prior trauma experiences, and specific types of traumas (sexual, physical and emotional). SETTING: The study was conducted at a forensic psychiatric hospital in Johannesburg, South Africa...

BACKGROUND: Globally, crime is highly masculinised and research into female criminality is scarce. In South Africa, no research specifically investigating the characteristics of female observandi referred for non-violent crimes has been published. AIMS: The study aimed to describe the socio-demographic, clinical, and forensic correlates in women referred to Sterkfontein Hospital for forensic psychiatric observation following a non-violent criminal charge between 2010 and 2019...

Depression is the most common psychiatric disorder that burdens modern society heavily. Numerous studies have shown that adverse childhood experiences can increase susceptibility to depression, and depression with adverse childhood experiences has specific clinical-biological features. However, the specific neurobiological mechanisms are not yet precise. Recent studies suggest that the gut microbiota can influence brain function and behavior associated with depression through the "microbe-gut-brain axis" and that the composition and function of the gut microbiota are influenced by early stress...

INTRODUCTION: Nigeria, with an estimated 40 million people living with mental disorders, faces a critical shortage of psychiatrists to address the significant burden. Despite psychotherapy being integral to psychiatric training, it lacks structure, consistency and adequate supervision. This is alarming, particularly given the substantial demand for specialized psychotherapeutic support among those with mental illness. METHODOLOGY: A cross-sectional study utilised an online survey targeting early career psychiatrists recruited from the Early Career Psychiatrists section of the Association of Psychiatrists in Nigeria...

BACKGROUND: Cognitive impairment is a growing problem with increasing burden in global aging. Older adults with major depressive disorder (MDD) have higher risk of dementia. Neurofilament light chain (NfL) has been proven as a potential biomarker in neurodegenerative disease, including dementia. We aimed to investigate the association between cognitive deficits and NfL levels in older adults with MDD. METHODS: In this cross-sectional study, we enrolled 39 MDD patients and 15 individuals with mild neurocognitive disorder or major neurocognitive disorder, Alzheimer's type, as controls, from a tertiary psychiatric hospital...

BACKGROUND: In the course of caring, nurses often experience the death of patients, and this experience has an effect on the nurse. Every nurse responds to this experience in a different way, and it can be either a negative emotional response, or a positive emotional response. As part of their curriculum, R425 first-year student nurses are placed in clinical facilities to acquire competency in nursing skills, and here they may be exposed to patients dying. R425 is a South African Nursing Council regulation relating to the approval of and the minimum requirements for the education and training of a nurse (General, Psychiatric, and Community) and Midwife, leading to registration...

OBJECTIVE: : Impulsivity can be observed in individuals with or without mental illness. The discovery of neural correlates responsible for trait impulsivity can therefore help to understand the severity of psychiatric symptoms, personality characteristics and social adjustment. In this study, we aimed to identify the gray matter substrates of trait impulsivity in healthy individuals. METHODS: : Seventy-five healthy individuals were enrolled. At baseline, trait impulsivity was assessed using the Barratt Impulsiveness Scale (BIS) and all participants underwent T1-weighted magnetic resonance imaging scan...

OBJECTIVE: Many psychiatric disorders are linked to low grade systemic inflammation as measured by systemic cytokine levels. Exploration of cytokines and immune activity and their role in psychiatric symptoms may inform pathobiology and treatment opportunities. The aim of this study is to explore if there are associations between cytokines and psychiatric symptom clusters. Comparison between patients regularly using and those not using psychotropic medication is also conducted. METHODS: This was a cross sectional naturalistic study with 132 participants from a general open inpatient psychiatric ward at the Nordland Hospital Trust, Norway...
