No differences were found for emotional abuse or physical/emotional neglect. Reduced cortical thickness in the right middle temporal gyrus and increased surface area in the right cingulate were found in UHR-T compared to UHR-NT individuals. Sexual abuse had an indirect effect on transition to psychosis, where decreased cortical thickness in the right middle temporal gyrus was a mediator.
 
  Results suggest that childhood sexual abuse negatively impacted on cortical development of the right temporal gyrus, and this heightened the risk of transition to psychosis in our sample. Further longitudinal studies are needed to precisely understand this link.

  Clinician-administered measures of negative symptoms may not capture patients' subjective experiences. The Self-Evaluation of Negative Symptoms (SNS) has shown good psychometric properties when used in outpatients with higher-level functioning schizophrenia. We aimed to evaluate the psychometric properties of the SNS in low functioning participants with treatment-resistant schizophrenia (TRS).
 
  Participants were assessed using the following measures at two time-points; time-point 1 SNS, Wide Range Achievement Test, 4th Edition Reading Subtest (WRAT-4), and Brief Assessment of Cognition in Schizophrenia (BACS). Time-point 2 (within a week of time-point 1) SNS, Negative Symptom Assessment 16 items (NSA-16), Scale to Assess Unawareness in Mental Disorder-Abbreviated (SUMD-A), Clinical Global Impression Severity Scale (CGI-S), Simpson Angus Scale (SAS), Calgary Depression Scale for Schizophrenia (CDSS), and the Patient Feasibility Questionnaire.
 
  Fifty participants with TRS were enrolled, a mean age of 43.8yeician-rated negative symptoms were not equivalent, except in a subgroup with higher cognitive functioning. This discrepant self-reporting appeared to relate to their low levels of insight and cognitive impairments.
 Participants with TRS and low functioning were able to respond to questions on the SNS regarding their subjective assessment of negative symptoms. However, self-reported and clinician-rated negative symptoms were not equivalent, except in a subgroup with higher cognitive functioning. This discrepant self-reporting appeared to relate to their low levels of insight and cognitive impairments.Research into the neurobiological processes that may lead to the onset of schizophrenia places growing emphasis on the glutamatergic system and brain development. Preclinical studies have shown that neurodevelopmental, genetic, and environmental factors contribute to glutamatergic dysfunction and schizophrenia-related phenotypes. Clinical research has suggested that altered brain glutamate levels may be present before the onset of psychosis and relate to outcome in those at clinical high risk. After psychosis onset, glutamate dysfunction may also relate to the degree of antipsychotic response and clinical outcome. These findings support ongoing efforts to develop pharmacological interventions that target the glutamate system and could suggest that glutamatergic compounds may be more effective in specific patient subgroups or illness stages. In this review, we consider the updated glutamate hypothesis of schizophrenia, from a neurodevelopmental perspective, by reviewing recent preclinical and clinical evidence, and discuss the potential implications for novel therapeutics.The Mas-related G protein-coupled receptor X2 (MRGPRX2) is a multiligand receptor responding to various exogenous and endogenous stimuli. Being highly expressed on skin mast cells, MRGPRX2 triggers their degranulation and release of proinflammatory mediators, and it promotes multicellular signaling cascades, such as itch induction and transmission in sensory neurons. The expression of MRGPRX2 by skin mast cells and the levels of the MRGPRX2 agonists (eg, substance P, major basic protein, eosinophil peroxidase) are upregulated in the serum and/or skin of patients with inflammatory and pruritic skin diseases, such as chronic spontaneous urticaria or atopic dermatitis. Therefore, MRGPRX2 and its agonists might be potential biomarkers for the progression of cutaneous inflammatory diseases and the response to treatment. In addition, they may represent promising targets for prevention and treatment of signs and symptoms in patients with skin diseases or drug reactions. To assess this possibility, this review explores the role and relevance of MRGPRX2 and its activators in cutaneous inflammatory disorders and chronic pruritus.TNFα inhibitors, including adalimumab, are widely used in inflammatory rheumatologic and bowel diseases. Well-known adverse effects include opportunistic infections, immunogenicity and new inflammatory manifestations. Myositis is an inflammatory disease, which manifests with muscle symptoms and can be life-threatening. Little is known about drug-induced myositis. We aimed to describe a case of myositis induced by adalimumab and reviewed national and international pharmacovigilance databases for other cases until 01/02/2019. This was a 63 years old woman with Crohn's disease, who developed muscle weakness, and rhabdomyolysis 3 months after starting adalimumab. Diagnosis of myositis was suspected and confirmed with electromyography and muscle biopsy. Improvement in muscle symptoms was observed after stopping adalimumab and starting corticosteroids. Muscular adverse effects are well-known and usually benign with adalimumab. However, five cases of myositis during treatment with adalimumab were registered in French PharmacoVigilance Database (FPVD) with muscle symptoms observed 3 months to 7 years after starting adalimumab. In VigiBaseⓇ, 90 cases of myositis associated with adalimumab with some similar characteristics were registered. When a patient treated with adalimumab complains of muscular symptoms, inflammatory myopathies should be considered.  https://www.selleckchem.com/products/hygromycin-b.html  This adverse effect should be mentioned in a 'Summary of Product Characteristics' to alert healthcare professionals.
