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...

PURPOSE: To prevent the incarceration and influence outcomes when criminal culpability is linked to postpartum psychosis. METHODS: Infanticide, neonaticide and filicide are most often linked with postpartum psychosis, which affects 1-2 women per 1,000 births or 4,000 women each year in the United States. Multiple genetic, hormonal and psychosocial factors surrounding childbirth result in a 1 to 4% risk of infanticide in women with postpartum psychosis. The authors seek to increase awareness of postpartum psychosis and postpartum depression in state legislatures...

A Gram-negative, motile, rod-shaped bacterial strain, CA-0114T , was isolated from the midgut of a western honey bee, Apis mellifera . The isolate exhibited ≤96.43 % 16S rRNA gene sequence identity (1540 bp) to members of the families Enterobacteriaceae and Erwiniaceae . Phylogenetic trees based on genome blast distance phylogeny and concatenated protein sequences encoded by conserved genes atpD , fusA, gyrB , infB , leuS , pyrG and rpoB separated the isolate from other genera forming a distinct lineage in the Enterobacteriaceae ...

Two Gram-negative, aerobic, rod-shaped bacterial strains, 7MK25T and 6Y81T , were isolated from forest soil of Dinghushan Biosphere Reserve, Guangdong Province, PR China.

Strain 6Y81T had the highest similarity of 97.9 % to Lichenibacterium minor RmlP026T , followed by Lichenibacterium ramalinae RmlP001T (97...

Butyrivibrio are anaerobic bacteria and members of the family Lachnospiraceae with important roles in fiber digestion in both animals and humans. This report describes the complete genome of Butyrivibrio fibrisolvens type strain D1T (DSM 3071) consisting of a chromosome (CP146963), megaplasmid (pNP243), and small plasmid (pNP21).

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...

In this commentary, I propose that a person-oriented and research-focused approach can stimulate the discussion on the definition of a traumatic stressor and help to refine Criterion A in the Diagnostic and Statistical Manual of Mental Disorders (DSM). Particularly, I suggest that a contextual perspective focusing on the interaction between event features and person-related factors captures more adequately the individual perception of and cognitions related to extremely threatening adverse life events for a diversity of individuals exposed to trauma...

The interplay between bacteria and their host influences the homeostasis of the human immune microenvironment, and this reciprocal interaction also affects the process of tissue damage repair. A variety of immunomodulatory commensal bacteria reside in the body, capable of delivering membrane vesicles (MVs) to host cells to regulate the local immune microenvironment. This research revealed, for the initial time, the significant enhancement of mucosal and cutaneous wound healing by MVs secreted by the human commensal Lactobacillus reuteri (RMVs) through modulation of the inflammatory environment in wound tissue...

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)...

Structurally complex corn bran arabinoxylan (CAX) was used as a model glycan to investigate gut bacteria growth and competition on different AX-based fine structures. Nine hydrolyzate segments of the CAX polymer varying in chemical structure (sugars and linkages), CAX, five less complex non-corn arabinoxylans, and xylose and glucose were ranked from structurally complex to simple. The substrate panel promoted different overall growth and rates of growth of eight Bacteroides xylan-degrading strains. For example, Bacteroides cellulosilyticus DSM 14838 ( Bacteroides cellulosilyticus ) grew well on an array of complex and simple structures, while Bacteroides ovatus 3-1-23 grew well only on the simple structures...

BACKGROUND: Coronavirus disease 2019 pandemic pointed out significant mental symptoms of frontline healthcare workers (HCWs).

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: The aim of our study is to examine the emotional, behavioral problems, and psychiatric symptoms of children diagnosed with Graves' disease (GD), to assess their quality of life, and to compare with control group. METHODS: The research was planned as a cross-sectional study and included 16 patients with GD (13 female and three male) and 29 healthy children for control group (19 female and 10 male). Sociodemographic form, Pediatric Quality of Life Inventory, Revised Child Anxiety and Depression Scale-Child Version (RCADS-CV), Strengths and Difficulties Questionnaire (SDQ), Turgay DSM-IV-Based Child and Adolescent Behavior Disorders Screening and Rating Scale (T-DSM-IV-S), and Affective Reactivity Index scale were applied to the children and their families...

Dural sinus malformation (DSM) is a rare vascular malformation characterized by the dilatation of a dural venous sinus with or without an anomalous jugular bulb. Its presentation with venous-reflux-related secondary proptosis is anecdotal, with only six such cases reported so far. We report a 17-month-old boy who presented with a progressive proptosis of the right eye secondary to a DSM of the transverse sinus and torcula. Following endovascular embolization of the arterio-venous fistula, complete thrombosis of the venous lake and improvement in proptosis was noted at 6-month follow-up...

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...

Cumulative trauma is usually devastating and can lead to severe psychological consequences, including posttraumatic stress disorder (PTSD). Exposure to various types of traumas, particularly during childhood, can be even more deleterious than the sheer number of events experienced. This epidemiological study is the first to investigate the impact of discrete childhood traumatic exposure on the risk of developing lifetime PTSD in a representative sample of the general population of the two biggest Brazilian cities...
