Exaggerated basal ganglia beta activity (13-35 Hz) is commonly found in patients with Parkinson's disease and can be suppressed by dopaminergic medication, with the degree of suppression being correlated with the improvement in motor symptoms. Importantly, beta activity is not continuously elevated, but fluctuates to give beta bursts. The percentage number of longer beta bursts in a given interval is positively correlated with clinical impairment in Parkinson's disease patients. Here we determine whether the characteristics of beta bursts are dependent on dopaminergic state...

High mobility group protein B1 (HMGB1) is a late inflammatory mediator released from inflammatory cells when stimulated, resulting in exaggerating septic symptoms. We recently demonstrated that full-length adiponectin, a potent anti-inflammatory adipokine, inhibits lipopolysaccharide-induced HMGB1 release. However, the effects of adiponectin on HMGB1-induced exaggerating signals currently remain unknown. This study aimed to investigate the effects of adiponectin on the pro-inflammatory function of HMGB1 in RAW264 macrophage cells...

Background: Network analysis is an emerging methodology for investigating psychopathological symptoms. Given the unprecedented number of refugees and the increased prevalence of mental disorders such as posttraumatic stress disorder (PTSD) in this population, new methodologies that help us better to understand psychopathology in refugees are crucial. Objective: The objective of this study was to explore the network structure and centrality indices of DSM-5 PTSD symptoms in a cross-sectional clinical sample of 151 severely traumatized refugees with and without a formal PTSD diagnosis...

Acanthosis nigricans (AN) is observed in some cases of skeletal dysplasia. However, AN has occasionally been reported in patients with hypochondroplasia (HCH), and a clinical diagnosis is sometimes difficult when its physical and radiological features are mild. Mutations in the gene encoding the fibroblast growth factor receptor 3 (FGFR3) have been identified as the cause of some types of skeletal dysplasia, which is diagnostically useful. Here, we report the case of a 3-yr-old Japanese boy who presented with AN...

We reply to Nichols' (2017) critique of our commentary on the MMPI-2/MMPI-2-RF Symptom Validity Scale (FBS/FBS-r) as a measure of symptom exaggeration versus a measure of litigation response syndrome (LRS). Nichols claims that we misrepresented the thrust of the original paper he co-authored with Gass; namely, that they did not represent that the FBS/FBS-r were measures of LRS but rather, intended to convey that the FBS/RBS-r were indeterminate as to whether the scales measured LRS or measured symptom exaggeration...

BACKGROUND: Disordered gamblers have phenotypical and pathological similarities to those with substance use disorders (SUD), including exaggerated automatic cognitive processing of motivationally salient gambling cues in the environment (i.e., attentional and approach bias). Cognitive bias modification (CBM) is a family of computerised interventions that have proved effective in successfully re-training these automatic cognitive biases in SUD. CBM interventions can, in principle, be administered online, thus showing potential of being a low-cost, low-threshold addition to conventional treatments...

We report the case of a 76-year-old woman presenting with 47-month history of progressive dementia and cortical blindness with no family history. Antibodies against thyroid glands and the N-terminus of α-enolase (NAE) were detected in her serum. Neurological examination revealed progressive dementia, frontal signs, visual disturbance, and exaggerated bilateral tendon reflexes in both legs. Diffusion MRI showed cortical hyper-intensities in the bilateral occipital and parietal, and the left frontal and temporal cortices...

BACKGROUND: Encephalitis is a syndrome of neurological dysfunction due to inflammation of the brain parenchyma, caused by an infection or an exaggerated host immune response, or both. Attenuation of brain inflammation through modulation of the immune response could improve patient outcomes. Biological agents such as immunoglobulin that have both anti-inflammatory and immunomodulatory properties may therefore be useful as adjunctive therapies for people with encephalitis. OBJECTIVES: To assess the efficacy and safety of intravenous immunoglobulin (IVIG) as add-on treatment for children with encephalitis...

Fragile X syndrome (FXS) is the leading cause of inherited intellectual disability, with additional symptoms including attention deficit and hyperactivity, anxiety, impulsivity, and repetitive movements or actions. The majority of FXS cases are attributed to a CGG expansion that leads to transcriptional silencing and diminished expression of fragile X mental retardation protein (FMRP). FMRP, an RNA binding protein, regulates the synthesis of dendritically-translated mRNAs by stalling ribosomal translation. Loss of FMRP leads to increased translation of some of these mRNAs, including the CNS-specific tyrosine phosphatase STEP (STriatal-Enriched protein tyrosine Phosphatase)...

A large body of evidence indicates that major affective disorders are accompanied by activated neuro-immune, neuro-oxidative and neuro-nitrosative stress (IO&NS) pathways. Postpartum depression is predicted by end of term prenatal depressive symptoms whilst a lifetime history of mood disorders appears to increase the risk for both prenatal and postpartum depression. This review provides a critical appraisal of available evidence linking IO&NS pathways to prenatal and postpartum depression. The electronic databases Google Scholar, PubMed and Scopus were sources for this narrative review focusing on keywords, including perinatal depression, (auto)immune, inflammation, oxidative, nitric oxide, nitrosative, tryptophan catabolites (TRYCATs), kynurenine, leaky gut and microbiome...

BACKGROUND: Research suggests that enhanced neural reactivity to errors, measured via the error-related negativity (ERN), is relatively unique to internalizing psychopathologies (IPs) and symptom clusters characterized by excessive worry and apprehension. However, no prior study has tested the association between the ERN and IP symptom dimensions in a heterogeneous, clinically representative patient population. The current study was designed to address this gap in the literature and clarify the role of the ERN in an adult IP treatment-seeking patient sample...

We provide original, international evidence documenting that self-assessed health (SAH) is a leading health indicator, that is, a significant predictor of future changes in health conditions, in a large sample of Europeans aged above 50 and living in 13 different countries. We find that, after controlling for attrition bias, lagged SAH is significantly and negatively correlated with changes in the number of chronic diseases, net of the correlations with levels, and changes in sociodemographic factors and health styles, country and regional health system effects, and declared symptoms...

Mevalonate Kinase Deficiency (MKD, OMIM #610377) is a rare autosomal recessive metabolic and inflammatory disease. In MKD, defective function of the enzyme mevalonate kinase (MK), due to a mutation in the MVK gene, leads to the shortage of mevalonate-derived intermediates, which results in unbalanced prenylation of proteins and altered metabolism of sterols. These defects lead to a complex multisystem inflammatory and metabolic syndrome. Although biologic therapies aimed at blocking the inflammatory cytokine interleukin-1 (IL-1) can significantly reduce inflammation, they cannot completely control the clinical symptoms that affects the nervous system...

OBJECTIVE: Freezing of gait is a poorly understood symptom of Parkinson disease, and can severely disrupt the locomotion of affected patients. However, bicycling ability remains surprisingly unaffected in most patients suffering from freezing, suggesting functional differences in the motor network. The purpose of this study was to characterize and contrast the oscillatory dynamics underlying bicycling and walking in the basal ganglia. METHODS: We present the first local field potential recordings directly comparing bicycling and walking in Parkinson disease patients with electrodes implanted in the subthalamic nuclei for deep brain stimulation...

OBJECTIVE: Roux-en-Y gastric bypass (RYGB) surgery is currently the most effective treatment for diabetes and obesity. An increasingly recognized and highly disabling complication of RYGB is postprandial hypoglycaemia (PPH). The pathophysiology of PPH remains unclear with multiple mechanisms suggested including nesidioblastosis, altered insulin clearance and increased glucagon-like peptide-1 (GLP-1) secretion. Whilst many PPH patients respond to dietary modification, some have severely disabling symptoms...

A small but significant proportion of mild traumatic brain injury (mTBI) sufferers will report persistent symptoms, including depression, anxiety and cognitive deficits, in the months, or even years, following the initial event. This is known as post-concussion syndrome and its pathogenesis is not yet known. This study sought to investigate the role of a peripheral inflammatory insult in the development of ongoing behavioral symptoms following a mTBI. To investigate, male Sprague-Dawley rats were administered a single mTBI using the diffuse impact-acceleration model to generate ∼100G of force...

Epstein-Barr virus (EBV) is typically acquired asymptomatically in childhood. In contrast, infection later in life often leads to infectious mononucleosis (IM), a febrile illness characterized by anti-EBV IgM antibody positivity, high loads of circulating latently infected B cells, and a marked lymphocytosis caused by hyperexpansion of EBV-specific CD8(+) T cells plus a milder expansion of CD56(dim) NKG2A(+) KIR(-) natural killer (NK) cells. How the two situations compare is unclear due to the paucity of studies on clinically silent infection...
