Major depressive disorder (MDD) is a common psychiatric disorder that is characterized by cognitive deficits and affective symptoms. To date, an increasing number of neuroimaging studies have focused on emotion regulation and have consistently shown that emotion dysregulation is one of the central features and underlying mechanisms of MDD. Although gray matter morphological abnormalities in regions within emotion regulation networks have been identified in MDD, the interactions and relationships between these gray matter structures remain largely unknown...

Relatively little is known about fatal motor vehicle accidents (FMVA) involving drivers with psychiatric disorders. In this study of all drivers killed in FMVAs in Finland between 1990 and 2011, we aimed to study drivers' death rate trends in FMVAs, with special focus on drivers with a history of psychiatric disorders. Prevalence of drivers' hospital treated psychiatric disorders, and characteristics of drivers with psychiatric disorders were also studied. For the purpose of this study, three national registers were accessed...

Serotonin modulates brain oscillatory activity, and serotonergic projections to the thalamus and cortex modulate the frequency of prefrontal rhythmic oscillations. Changes in serotonergic tone have been reported to shift oscillations between the combined delta-theta (2.5-8 Hz) and the alpha (8-12 Hz) frequency ranges. Such frequency shifts may constitute a useful biomarker for the effects of selective serotonin reuptake inhibitor (SSRI) medications in Major Depressive Disorder (MDD). We utilized quantitative electroencephalography (qEEG) to measure shifts in prefrontal rhythmic oscillations early in treatment with either the SSRI escitalopram or placebo, and examined the relationship between these changes and remission of depressive symptoms...

Adenine phosphoribosyltransferase (APRT) deficiency is a hereditary disorder that leads to excessive urinary excretion of 2,8-dihydroxyadenine (DHA), causing nephrolithiasis and chronic kidney disease. Treatment with allopurinol or febuxostat reduces DHA production and attenuates the renal manifestations. Assessment of DHA crystalluria by urine microscopy is used for therapeutic monitoring, but lacks sensitivity. We report a high-throughput assay based on ultra-performance liquid chromatography coupled to tandem mass spectrometry (UPLC-MS/MS) for quantification of urinary DHA...

BACKGROUND: Previous studies of patients with bipolar disorder (BD) using magnetic resonance spectroscopy (MRS) have shown neurophysiological abnormalities related to the glutamate (Glu)-glutamine (Gln) cycle, membrane turnover, and neuronal integrity, although the results were neither consistent nor conclusive. Recently it has been reported the Gln/Glu ratio is the most useful index, quantifying neuronal-glial interactions and the balance of glutamatergic metabolites In this MRS study, we elucidated the abnormalities of metabolites in a larger sample of patients with BD with a high-field MRI system...

Febrile infection-related epilepsy syndrome (FIRES) is a devastating epileptic encephalopathy with limited treatment options and an unclear etiology. Anakinra is a recombinant version of the human interleukin-1 receptor antagonist used to treat autoinflammatory disorders. This is the first report of anakinra for treatment of a child with super-refractory status epilepticus secondary to FIRES. Anakinra was well-tolerated and effective. Cerebral spinal fluid analysis revealed elevated levels of proinflammatory cytokines before treatment that normalized on anakinra, suggesting a potential pathogenic role for neuroinflammation in FIRES...

Polyglutamine (polyQ) diseases comprise a group of nine genetic disorders that are caused by the expansion of the CAG triplet repeat, which encodes glutamine, in unrelated single genes. Various oligonucleotide (ON)-based therapeutic approaches have been considered for polyQ diseases. The very attractive CAG repeat-targeting strategy offers selective silencing of the mutant allele by directly targeting the mutation site. CAG repeat-targeting miRNA-like siRNAs have been shown to specifically inhibit the mutant gene expression, and their characteristic feature is the formation of mismatches in their interactions with the target site...

In axons, proper localization of proteins, vesicles, organelles, and other cargoes is accomplished by the highly regulated coordination of kinesins and dyneins, molecular motors that bind to cargoes and translocate them along microtubule (MT) tracks. Impairment of axonal transport is implicated in the pathogenesis of multiple neurodegenerative disorders including Alzheimer's and Huntington's diseases. To understand how MT-based cargo motility is regulated and to delineate its role in neurodegeneration, it is critical to analyze the detailed dynamics of moving cargoes inside axons...

Many individuals with ASD have a distinctive behavioral presentation that is recognizable within moments, a phenomenon we call "frank" ASD. This phenomenon has been discussed informally for decades, perhaps as "classic" ASD; however, there is no unitary "classic" presentation, and classic autism does not seem to correspond to level of functioning. Thus, neither "frank" nor "classic" autism has been delineated or studied as a research construct. To initiate the empirical study of frank ASD, we surveyed 151 clinicians, from a range of disciplines that diagnose ASD, about this phenomenon...

Survivorship after pediatric HCT has increased over the past decade. Focus on long-term care and well-being remains critical due to risk of poor dietary habits and exaggerated sedentary behavior, which can lead to muscle weakness, increased risk for obesity, and cardiometabolic disorders. Nutrition and physical activity are key factors in survivorship; however, data are limited. Comprehensive nutritional assessments, including nutrition-focused physical examination, grip strength, and food/activity surveys, were completed in 36 pediatric HCT survivors (aged 2-25 years)...

Itch, the unpleasant sensation that evokes a desire to scratch, accompanies numerous skin and nervous system disorders. However, the molecular mechanisms of itch are unclear. Acid sensing ion channel 3 (ASIC3) is a sensor of acidic and primary inflammatory pain. The whole-cell patch-clamp technique was used to determine the effect of Chloroquine (CQ)on ASICs currents in primary sensory neurons or the Chinese hamster ovary (CHO) cells transfected with rat-ASIC1a or- ASIC3. Site-directed mutagenesis of plasmid was performed...

Lithium has been a gold standard in the treatment of bipolar disorder (BD) for several decades. Despite a general reduction in the use of lithium over the past several years, it is effective in the management of both manic and depressive episodes in BD and continues to be recommended as a first-line mood stabilizer. This review provides an overview of the pharmacology of lithium and highlights its clinical profile in the management of BD, focusing on the potential advantages of prolonged-release (PR) versus immediate-release (IR) formulations of lithium...

Rapid eye movement sleep behavior disorder (RBD) is thought to be one of the most frequent preceding symptoms of Parkinson's disease (PD). However, the prevalence of RBD in PD stated in the published studies is still inconsistent. We conducted a meta and meta-regression analysis in this paper to estimate the pooled prevalence. We searched the electronic databases of PubMed, ScienceDirect, EMBASE and EBSCO up to June 2016 for related articles. STATA 12.0 statistics software was used to calculate the available data from each research...

Developmental models of pediatric anxiety posit multiple, maladaptive parenting behaviors as potential risk factors. Despite this, a standardized means of assessing multiple of these practices (i.e., anxiogenic parenting) in a comprehensive and efficient manner are lacking. In Study 1531 parents of children 7-17 years old completed an online survey via Amazon Mechanical Turk. In Study 2, a separate community sample (N = 109; 9-17 years old) was recruited and completed a comprehensive assessment battery as part of a larger study...

The VA has integrated psychologists and other licensed mental health providers, known collectively as co-located collaborative care (CCC) providers, into patients' primary care medical homes to improve mental health services for veterans. However, it is unclear if CCC providers are routinely using mental health measures as part of evidence-based, coordinated care. This study aimed to determine the prevalence and predictors of CCC provider utilization of brief, validated measures. A retrospective review of VA electronic medical records from 8403 veterans diagnosed with depression, posttraumatic stress disorder, or anxiety disorder was conducted...
