Autoantibodies against myelin sheath and S100β are associated with cognitive dysfunction in patients with rheumatoid arthritis.

Rheumatoid arthritis (RA) has been associated with cognitive impairment and peripheral production of autoantibodies. Autoantibodies against central nervous system (CNS) proteins and S100 calcium-binding β (S100β) were found increased in diseases characterized by cognitive impairment like Alzheimer disease and Neuropsychiatric Systemic Lupus Erythematosus (NPSLE). The aim of this study was to investigate the plasma levels of autoantibodies against myelin basic protein (anti-MBP), myelin oligodendrocyte glycoprotein (anti-MOG) and S100β, and their relationships with cognitive performance in RA patients.

Theory of Mind Impairments in Women With Cocaine Addiction.

Objective: This study investigates the Theory of Mind performance of female cocaine-dependent users (CDUs) and possible associations between theory of mind performance and features of cocaine use.

Method: Sixty women controlled for age, education, individual income, and IQ participated in this study: 30 in the CDU group and 30 in the healthy control group. Participants were assessed for theory of mind with the Reading the Mind in the Eyes Test (RMET), a test of understanding of first-order and second-order false beliefs, and the Hinting task.

Culture-sensitive psychotraumatology.

Background: Although there is some evidence of the posttraumatic stress disorder (PTSD) construct's cross cultural validity, trauma-related disorders may vary across cultures, and the same may be true for treatments that address such conditions. Experienced therapists tailor psychotherapy to each patient's particular situation, to the nature of the patient's psychopathology, to the stage of therapy, and so on. In addition, culture-sensitive psychotherapists try to understand how culture enhances the meaning of their patient's life history, the cultural components of their illness and help-seeking behaviors, as well as their expectations with regard to treatment.

Crack-cocaine dependence and aging: effects on working memory.

Objective: To compare the working memory (WM) performance of young adult crack-cocaine dependent users, healthy older adults, and a control group of healthy young adults.

Methods: A total of 77 female participants took part in this study: 26 young adult crack-cocaine dependent users (CRK), 19 healthy older adults (HO), and 32 healthy younger adults (HC). All participants completed the N-back verbal task.

Toll-like receptor expression and function in type I bipolar disorder.

Bipolar disorder (BD) has been associated with immune imbalance and low-grade inflammation. The underlying mechanisms remain largely obscure but may involve changes in cell signaling. Toll-like receptors (TLRs) are widely expressed by immune cells.

Early stages of bipolar disorder: characterization and strategies for early intervention.

Objective: To characterize the early stages of bipolar disorder (BD), defined as the clinical prodrome/subsyndromal stage and first-episode phase, and strategies for their respective treatment.

Methods: A selective literature search of the PubMed, Embase, PsycINFO, and ISI databases from inception until March 2014 was performed. Included in this review were articles that a) characterized prodromal and first-episode stages of BD or b) detailed efficacy and safety/tolerability of interventions in patients considered prodromal for BD or those with only one episode of mania/hypomania.

Long-term cannabis abuse and early-onset cannabis use increase the severity of cocaine withdrawal during detoxification and rehospitalization rates due to cocaine dependence.

Background: Long-term and early-onset cannabis consumption are implicated in subsequent substance- related problems. The aim of this follow-up study was to investigate whether these patterns of cannabis use could impact cocaine withdrawal severity and cocaine craving intensity during detoxification. In addition, we investigated their impact in the rehospitalization rates due to cocaine dependence 2.

Pro-inflammatory cytokines and soluble receptors in response to acute psychosocial stress: differential reactivity in bipolar disorder.

Mounting evidence suggests a chronic pro-inflammatory state in individuals with bipolar disorder (BD). Stress exposure is known to exacerbate several inflammatory conditions as well as psychiatric disorders. Here, we analyzed plasma levels of pro-inflammatory cytokines and their soluble receptors to realistic acute psychosocial stress challenge in BD.

Dual-memory processes in crack cocaine dependents: The effects of childhood neglect on recall.

Exposure to adversities during sensitive periods of neurodevelopment is associated with the subsequent development of substance dependence and exerts harmful, long-lasting effects upon memory functioning. In this study, we investigated the relationship between childhood neglect (CN) and memory using a dual-process model that quantifies recollective and non-recollective retrieval processes in crack cocaine dependents. Eighty-four female crack cocaine-dependent inpatients who did (N = 32) or did not (N = 52) report a history of CN received multiple opportunities to study and recall a short list composed of familiar and concrete words and then received a delayed-recall test.

Mothers who were sexually abused during childhood are more likely to have a child victim of sexual violence.

Introduction: Recurrent exposure to childhood sexual abuse (CSA) seems to be higher among victims of sexual abuse. In this sense, experiences related to sexual violence can perpetuate within the family context itself in various ways. Here, we investigate the association between being exposed to CSA and having a child victim of sexual abuse.

Early life stress and tumor necrosis factor superfamily in crack cocaine withdrawal.

Background: Both early life stress (ELS) and substance abuse, especially cocaine, have robust effects on the inflammatory system. Considering the role of the tumor necrosis factor system in inflammatory signaling and its association with ELS, the aim of the study was to compare plasma levels of TNF-alpha, its soluble receptors and ligands during early abstinence of crack cocaine.

Methods: This study included 24 crack cocaine-dependent women with (CRACK-ELS) and 20 without (CRACK) a history of ELS.

Childhood Trauma Questionnaire (CTQ) in Brazilian samples of different age groups: findings from confirmatory factor analysis.

The Childhood Trauma Questionnaire (CTQ) is internationally accepted as a key tool for the assessment of childhood abuse and neglect experiences. However, there are relative few psychometric studies available and some authors have proposed two different factor solutions. We examined the dimensional structure and internal consistency of the Brazilian version of the CTQ.

Neurotrophic factors in women with crack cocaine dependence during early abstinence: the role of early life stress.

Background: Neurotrophic factors have been investigated in the pathophysiology of alcohol and drug dependence and have been related to early life stress driving developmental programming of neuroendocrine systems.

Methods: We conducted a follow-up study that aimed to assess the plasma levels of glial cell line-derived neurotrophic factor (GDNF), brain-derived neurotrophic factor (BDNF), nerve growth factor (NGF), neurotrophin-3 (NT3) and neurotrophin-4/5 (NT4/5) in crack users during 3 weeks of early abstinence in comparison with healthy controls. We performed a comprehensive clinical assessment in female inpatients with crack cocaine dependence (separated into 2 groups: participants with (CSA+) and without (CSA-) a history of childhood sexual abuse) and a group of nonuser control participants.

Childhood maltreatment and inflammatory markers: a systematic review.

Objective: Childhood maltreatment (CM) has been associated with several diseases in adult life, including diabetes, obesity and mental disorders. Inflammatory conditions have been postulated as possible mediators of this relationship. The aim was to conduct a systematic review regarding the association between CM and inflammatory markers in adulthood.

Childhood neglect and increased withdrawal and depressive severity in crack cocaine users during early abstinence.

Studies have shown that environmental factors, such as exposure to childhood maltreatment, might shift the course of addiction. Little is known, however, about whether childhood physical neglect (PN) influences the severity of withdrawal and depressive symptoms during the detoxification period. This is a 3 weeks follow-up study.

Adipokines during early abstinence of crack cocaine in dependent women reporting childhood maltreatment.

Childhood maltreatment has been associated with addiction and immune dysregulation, although neurobiological substrates underlying this association remain largely unknown. The aim of the study was to compare plasma levels of adipokines during early abstinence in crack cocaine dependent women with (CM+) and without history of childhood maltreatment (CM-). One hundred four crack cocaine female users were followed for 20 days in a detoxification inpatient treatment unit.

Executive functions rehabilitation for schizophrenia: a critical systematic review.

Background: Consistent evidences suggest that poor functional outcomes in schizophrenia are associated with deficits in executive functions (EF). As result cognitive training, remediation and/or rehabilitation (CR) programs have been developed and many theories, methods and approaches have emerged in support of them. This article presents a systematic review of randomized controlled trials (RCT), including EF rehabilitation interventions, with a focus on methodological issues and evidences of EF improvements.
