Prenatal exposure to endocrine disrupting chemicals and the association with behavioural difficulties in 7-year-old children in the SELMA study.

Background: Endocrine disrupting chemicals (EDCs) can cross the placenta and thereby expose the fetus, which may lead to developmental consequences. It is still unclear which chemicals are of concern regarding neurodevelopment and specifically behaviour, when being exposed to a mixture.

Objective: The objective is to determine associations between prenatal exposure to EDCs and behavioural difficulties.

Gender-specific play behavior in relation to autistic traits and behavioral difficulties at the age of seven in the SELMA study.

Background: Childhood gender nonconformity is related to psychological distress and behavioral difficulties. Similarly, there is evidence for a link between gender nonconformity, or gender dysphoria in some studies, and autism spectrum disorder and related traits. Our knowledge on those associations mostly originates from clinical populations, which might lead to overestimation.

Early and late contingent negative variation (CNV) reflect different aspects of deficits in schizophrenia.

Abnormal reward processing and psychomotor slowing are well-known in schizophrenia (SZ). As a slow frontocentral potential, contingent negative variation (CNV) is associated with anticipatory attention, motivation and motor planning. The present study aims to evaluate the early and late amplitude and latencies of CNV in patients with SZ compared to healthy controls during a reward processing task and to show its association with clinical symptoms.

DNA methylation at DLGAP2 and risk for relapse in alcohol dependence during acamprosate treatment.

Background: Alcohol use disorders are prevalent mental disorders with significant health implications. Epigenetic alterations may play a role in their pathogenesis, as DNA methylation at several genes has been associated with these disorders. We have previously shown that methylation in the DLGAP2 gene, coding for a synaptic density protein, is associated with alcohol dependence.

Reduced Reward Processing in Schizophrenia: A Comprehensive EEG Event-Related Oscillation Study.

It is well known that abnormal reward processing is a characteristic feature of various psychopathologies including schizophrenia (SZ). Reduced reward anticipation has been suggested as a core symptom of SZ. The present study aims to evaluate the event-related oscillations (EROs) delta, theta, alpha, beta, and gamma in patients with SZ during the Monetary Incentive Delay (MID) task, which elicits the neural activity of reward processing.

Enhanced Punishment Responses in Patients With Schizophrenia: An Event-Related Potential Study.

It is well known that abnormal reward processing is a characteristic feature of various psychopathologies including schizophrenia. Reduced reward anticipation has been suggested as a core symptom of schizophrenia. The Monetary Incentive Delay Task (MID) is frequently used to detect reward anticipation.

Prenatal exposure to phthalates and gender-specific play behavior at seven years of age in the SELMA study.

Background: A growing body of evidence shows that prenatal exposure to phthalates affects child development. Since many phthalates have been shown to alter endocrine signaling, they may influence reproductive development, neurodevelopment, and child behavior. Indeed, a few studies reported associations between prenatal phthalate exposure and gender-specific play behavior.

The Relationship Between Cardiovascular Disease Risk and Major Depression.

Introduction: Cardiovascular risk in depression has been investigated in small clinical samples and population-based studies revealing inconclusive results. However, cardiovascular risk in drug-naive depressed patients has not been tested extensively.

Methods: Body mass index-based Framingham Cardiovascular Risk Scores and soluble intercellular adhesion molecule-1 (sICAM-1) levels were used to assess the risk of cardiovascular disease in drug-naive depressed patients and healthy volunteers.

Exploring gender dysphoria and related outcomes in a prospective cohort study: protocol for the Swedish Gender Dysphoria Study (SKDS).

Introduction: There has been a drastic increase in the reported number of people seeking help for gender dysphoria in many countries over the last two decades. Yet, our knowledge of gender dysphoria and related outcomes is restricted due to the lack of high-quality studies employing comprehensive approaches. This longitudinal study aims to enhance our knowledge of gender dysphoria; different aspects will be scrutinised, focusing primarily on the psychosocial and mental health outcomes, prognostic markers and, secondarily, on the underlying mechanisms for its origin.

Psychosocial health modifies associations between HPA-axis function and brain structure in older age.

Background: Dysregulation of the negative feedback loop of the hypothalamic-pituitary-adrenal (HPA) axis may have damaging effects on the brain, potentially under influence of psychosocial health factors. We studied associations between functioning of the negative feedback loop of HPA-axis, measured with a very low-dose dexamethasone suppression test (DST), and brain structure in middle-aged and older adults, and whether these associations were modified by psychosocial health.

Methods: From 2006 to 2008, 1259 participants (mean age 57.

Associations Between Blood Levels of NLRP3 Inflammasome Components and Obsessive Compulsive Disorder.

Introduction: Even though the effect of inflammation on pathogenesis of obsessive compulsive disorder (OCD) is known, information regarding the underlying mechanisms are yet to be revealed. The NLRP3 inflammasome complex is an important component of the innate immune system that initiates and mediates inflammatory response to a variety of stimuli. This study aims to inquire into a possible association between NLRP3 inflammasome complex and OCD.

Exposure to endocrine-disrupting chemicals and implications for neurodevelopment.

Human brain development is a complex multistep process that is partly coordinated by the endocrine system. Any interference with the endocrine system might affect this process and result in deleterious outcomes. Endocrine-disrupting chemicals (EDCs) represent a large group of exogenous chemicals with the capacity of interfering with endocrine functions.

Growth Characteristics of Long-Nosed Skate (Linnaeus, 1758) Inhabiting the Northeastern Mediterranean Sea.

This study aims to determine the age and growth characteristics of living in the Northeastern Mediterranean Sea and to present data that can provide a comparison with previous studies on the same subject. A total of 255 long-nose skates at a total length of 12.2-93.

Associations of neuroimaging markers with depressive symptoms over time in middle-aged and elderly persons.

Background: Cerebrovascular disease is regarded as a potential cause of late-life depression. Yet, evidence for associations of neuroimaging markers of vascular brain disease with depressive symptoms is inconclusive. We examined the associations of neuroimaging markers and depressive symptoms in a large population-based study of middle-aged and elderly persons over time.

Impact of endocrine disrupting chemicals on neurodevelopment: the need for better testing strategies for endocrine disruption-induced developmental neurotoxicity.

Introduction: Brain development is highly dependent on hormonal regulation. Exposure to chemicals disrupting endocrine signaling has been associated with neurodevelopmental impairment. This raises concern about exposure to the suspected thousands of endocrine disruptors, and has resulted in efforts to improve regulation of these chemicals.

Schizophrenia in microcephalic osteodysplastic primordial dwarfism type II syndrome: supporting evidence for an association between the PCNT gene and schizophrenia.

Schizophrenia is a genetically complex disease that is related to neurodevelopmental abnormalities. Several genetic polymorphisms and genetic syndromes associated with neurodevelopmental processes have been linked to schizophrenia. In this case report, we present a case with an association between microcephalic osteodysplastic primordial dwarfism type II and schizophrenia.
