OBJECTIVE: Trauma exposure and posttraumatic stress (PTS) are prominent risk factors for problematic substance use, but little research has evaluated the mechanisms that link PTS and substance use. Emerging research supports the utility of reward probability (i.e., access to and pleasure experienced in response to environmental reward) as a mediator of the relationship between trauma and alcohol use problems. However, no existing studies have examined whether reward probability mediates the link between posttraumatic stress (PTS) and cannabis use in trauma exposed individuals...

OBJECTIVES: Although the relationship between traumatic experiences (TEs) and psychosomatic manifestations (pain, somatization, somatosensory amplification [SSA], and alexithymia) has been widely described, very few studies have investigated how these variables correlate with each other and with a history of TEs. The aim of this study was to investigate whether and how current psychosomatic manifestations are correlated with major and minor adult- and childhood TEs. METHODS: One hundred and forty-six patients (91 with pain) from the Pisa Gift Institute for Integrative Medicine Psychosomatics Lab...

Objective: To investigate the prevalence and correlates of eating disorder symptoms in adolescents with bipolar I disorder (BP I). Methods: We retrospectively collected a DSM-IV-TR -based diagnostic assessment of 179 adolescents with BP I and evaluated clinical variables in those with and without eating disorder symptoms. For comparison, we retrospectively evaluated eating disorder symptoms in adolescents with generalized anxiety disorder (GAD). Results: Thirty-six percent of adolescents with BP I experienced lifetime eating disorder symptoms; among comorbid adolescents, 74% reported eating disorder cognitions and 40% reported symptoms related to bingeing, 25% purging, and 17% restricting...

PURPOSE: Child maltreatment (CM) is associated with psychosis; however little is known about the frequency, type, and timing of abuse in the personality pathology domain of psychoticism (PSY) in the DSM-5. The purpose of this study was to analyze childhood trauma typology and frequency according to gender and to identify sensitive periods of susceptibility to CM in women with high PSY. METHODS: The Maltreatment and Abuse Chronology Exposure (MACE) scale was used to evaluate the frequency, severity and timing of each type of maltreatment...

BACKGROUND: Discovering biological markers is essential for understanding and treating mental disorders. Despite the limitations of current non-invasive methods, neural progenitor cells from the olfactory epithelium (hNPCs-OE) have been emphasized as potential biomarker sources. This study measured soluble factors in these cells in Major Depressive Disorder (MDD), Borderline Personality Disorder (BPD), and healthy controls (HC). METHODS: We assessed thirty-five participants divided into MDD (n=14), BPD (n=14), and HC (n=7)...

Microplastics (MPs) can act as carriers of environmental arsenic species into the stomach with food and release arsenic species during digestion, which threatens human health. Herein, an integrated dynamic stomach model (DSM)-capillary electrophoresis-inductively coupled plasma mass spectrometry (CE-ICPMS) is developed for online monitoring of the release and transformation behaviors of arsenic species loaded on MPs (As-MPs) in the simulated human stomach. The 3D-printed DSM with a soft stomach chamber enables the behaviors of gastric peristalsis, gastric and salivary fluid addition, pH adjustment, and gastric emptying (GE) to be controlled by a self-written program after oral ingestion of food with As-MPs...

Two Gram-negative, aerobic, rod-shaped bacterial strains, 7MK25T and 6Y81T , were isolated from forest soil of Dinghushan Biosphere Reserve, Guangdong Province, PR China. Based on the results of 16S rRNA gene sequence analysis, strain 7MK25T showed the highest similarity (93.6 %) to Methyloferula stellata AR4T , followed by Bosea thiooxidans DSM 9653T (93.3 %). Strain 6Y81T had the highest similarity of 97.9 % to Lichenibacterium minor RmlP026T , followed by Lichenibacterium ramalinae RmlP001T (97...

Treatment with long-acting injection (LAI) antipsychotics, such as paliperidone palmitate, has improved the quality of life in terms of symptoms and prevention of relapses in patients with schizophrenia. Although there are plenty of evidences about the efficacy and safety of paliperidone palmitate 3-monthly injection (PP3M) in adults with schizophrenia, literature appears lacking about the use of LAIs during pregnancy. We hereby describe the clinical case of a pregnant woman affected by schizophrenia (DSM-5-TR), taking pharmacological treatment of PP3M...

BACKGROUND: There are major challenges in determining the aetiology of vascular cognitive impairment (VCI) clinically, especially in the presence of mixed pathologies, such as vascular and amyloid. Most recently, two criteria (American Heart Association/American Stroke Association [AHA/ASA] and Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition [DSM-V]) have been proposed for the clinical diagnosis of VCI but have not as yet been validated using neuroimaging. AIMS: This study aims to determine whether the AHA/ASA and DSM-V criteria for VCI can distinguish between cases with predominantly vascular pathology and cases with mixed pathology...

Since the publication of the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) , identity impairment has become a diagnostic criterion for all personality disorders. The current study examined the occurrence of identity dimensions, clinically relevant identity impairments and personality pathology, and associations between these constructs in 92 forensic patients and 139 healthy controls. Patients showed higher levels of almost all identity dimensions, identity impairments, personality disorders, and almost all maladaptive personality traits than controls...

INTRODUCTION: Visual Schema Displacement Therapy (VSDT) is a novel approach showing promise in mitigating distressing memories, akin to Eye Movement Desensitization and Reprocessing (EMDR). OBJECTIVES: This study aimed to determine the safety, feasibility, and effectiveness of VSDT in individuals with post-traumatic stress disorder (PTSD), comparing it to EMDR therapy and a waitlist control condition (WLCC). It was hypothesized that the application of VSDT would be safe and PTSD symptoms significantly be reduced from both baseline to post-treatment and from baseline to follow-up in the VSDT and EMDR therapy conditions...

AIM: Corallococcus species are diverse in the natural environment with ten new Corallococcus species having been characterised in just the last five years. As well as being an abundant myxobacterial genus they produce several secondary metabolites, including Corallopyronin, Corramycin, Coralmycin and Corallorazine. We isolated a novel strain Corallococcus spp RDP092CA from soil in South Wales, United Kingdom using Candida albicans as prey bait and characterised its predatory activities against pathogenic bacteria and yeast...

This was a double-blind, randomized, phase 2 study of adults (18-64 years) with DSM-5 diagnosis of major depressive disorder (MDD), with moderate-to-severe episode severity (Montgomery-Åsberg Depression Rating Scale [MADRS] ≥25) despite an adequate course with ongoing antidepressant for ≥6 weeks to ≤12 months. Following a double-blind placebo lead-in period (up to 3 weeks), participants were randomized to receive once daily aticaprant 10 mg or continue placebo, added to their ongoing treatment, for 6 weeks...

Background Internally displaced persons (IDP) camps are still home to a large number of female survivors of the Yazidi genocide carried out in Iraq in 2014 by the Islamic organization known as the Islamic State of Iraq and Syria (ISIS). Many of these women suffer from a persistent form of post-traumatic stress disorder (PTSD), which can last for many years. On the other hand, little is known about the intricate etiology of PTSD. Objectives In this observational cross-sectional study, the biochemical parameters, including inflammatory and oxidative stress (OXS) markers, were evaluated in two groups: the case group (women with newly diagnosed PTSD) and the control group (apparently healthy women)...

BACKGROUND: Coronavirus disease 2019 pandemic pointed out significant mental symptoms of frontline healthcare workers (HCWs). OBJECTIVE: We aimed to estimate the prevalence and comorbidity of post-traumatic stress symptoms (PTSS), depression and anxiety symptoms in HCWs from Fangcang shelter hospitals during the pandemic. DESIGN: Demographic information, post-traumatic stress disorder checklist for DSM-5 (PCL-5), Patient Health Questionnaire (PHQ-9) and Generalized Anxiety Disorder Questionnaire (GAD-7) were obtained online based on stratified random sampling design during April 2022, with 284 eligible responses...

OBJECTIVES: This study aimed to investigate the relationship between suicidal ideation at baseline and the development of post-traumatic stress disorder (PTSD) in individuals who have experienced physical injuries, with a specific focus on how this relationship is moderated by the patient's functioning level. METHODS: Participants were consecutively recruited from a trauma center and prospectively followed for two years. At baseline, suicidal ideation was assessed using the Brief Psychiatric Rating Scale, and functioning level was evaluated using the Social and Occupational Functioning Assessment Scale...

BACKGROUND: The difficulty is remained to accurately distinguish bipolar disorder (BD) from major depressive disorder (MDD) in early stage, with a delayed diagnosis for 5-10 years. BD patients are often treated with antidepressants systematically due to being diagnosed with MDD, affecting the disease course and clinical outcomes. The current study aims to explore the role of plasma exosomes as biomarker to distinguish BD from MDD in early stage. METHODS: Two stages are included...

OBJECTIVES: Delirium is most often reported as present or absent. Patients with symptoms falling short of the diagnostic criteria for delirium fall into 'no delirium' or 'control' groups. This binary classification neglects individual symptoms and may be hindering identification of the pathophysiology underlying delirium. This systematic review investigates which individual symptoms of delirium are reported by studies of postoperative delirium in adults. METHODS: Medline, EMBASE and Web of Science databases were searched on 03 June 2021 and 06 April 2023...

In the field of medical aesthetics and plastic surgery, it is not uncommon to interact with clients who never seem to be satisfied, regardless of the success of an intervention. Medical professionals may attribute this to the patient having an overly critical nature; however, this continual dissatisfaction could also be the result of a mental health disorder known as body dysmorphic disorder (BDD) that is significantly underdiagnosed and prevalent within the plastic surgery and aesthetic patient population...

BACKGROUND: The DSM Level 1 Cross-Cutting Symptom Measure (DSM-XC) allows for assessing multiple psychopathological domains. However, its capability to screen for mental disorders in a population-based sample and the impact of adverbial framings (intensity and frequency) on its performance are unknown. METHODS: The study was based on cross-sectional data from the 1993 Pelotas birth cohort in Brazil. Participants with completed DSM-XC and structured diagnostic interviews ( n = 3578, aged 22, 53...
