#1
Laura Thompson, Rose McCabe
Consultations for patients with chronic mental health conditions are conceived as meetings of experts: medical and experiential, respectively. Treatment decisions, in these terms, become a joint responsibility rather than handed down ex-cathedra. One resource for constituting decisions as 'shared' is the treatment recommendation - decisional authority can be invoked through its design. There is concern that people diagnosed with schizophrenia are infrequently involved in treatment decisions. However, the methods psychiatrists actually employ remain undefined...

In this paper we describe an open-access collection of multimodal neuroimaging data in schizophrenia for release to the community. Data were acquired from approximately 100 patients with schizophrenia and 100 age-matched controls during rest as well as several task activation paradigms targeting a hierarchy of cognitive constructs. Neuroimaging data include structural MRI, functional MRI, diffusion MRI, MR spectroscopic imaging, and magnetoencephalography. For three of the hypothesis-driven projects, task activation paradigms were acquired on subsets of ~200 volunteers which examined a range of sensory and cognitive processes (e...

BACKGROUND: Postinjection delirium/sedation syndrome (PDSS) has been reported uncommonly during treatment with olanzapine long-acting injection (LAI), a sustained-release formulation of olanzapine. AIMS: The primary aim of the study was to estimate the incidence per injection and per patient of PDSS events in adult patients with schizophrenia who were receiving olanzapine LAI in real-world clinical practice. Secondary aims were to further characterise the clinical presentation of PDSS events, to identify potential risk factors associated with PDSS events and to characterise hospitalisations at baseline and post-baseline...

Patients with schizophrenia have difficulty in making sensory predictions, in the time domain, which have been proposed to be related to self-disorders. However experimental evidence is lacking. We examined both voluntary and automatic forms of temporal prediction in 28 patients and 24 matched controls. A visual cue predicted (temporal cue) or not (neutral cue) the time (400 ms/1000 ms) at which a subsequent target was presented. In both patients and controls, RTs were faster for targets presented after long versus short intervals due to the temporal predictability inherent in the elapse of time ("hazard function")...

Although abnormalities in emotional response have long been considered a core feature of the chronic phase of schizophrenia, few investigations have examined emotional response in individuals at ultrahigh-risk (UHR) for psychosis. We investigated whether neuroleptic-free UHR (n=29) and healthy control (n=32) participants differed in emotional reactivity and emotion regulation on a laboratory-based task that required reporting levels of positive and negative affect to pleasant, unpleasant, and neutral stimuli...

AIM: This study aimed to estimate the relative representation of childhood psychiatric diagnoses and use of psychotropic medication in the Danish National Birth Cohort (DNBC) compared to the general population. METHODS: The general population was identified as all childbirths in Denmark during 1998-2002 ( N=344,160). Linking the DNBC ( N=91,442) and the general population to the Danish national health registries, all children were followed until they received an ICD-10 psychiatric diagnosis, had a prescription of psychotropic medication or to the end of follow-up in 2013...

Polysialic acid (polySia) is mainly found as a modification of neural cell adhesion molecule (NCAM) in whole embryonic brains, as well as restricted areas of adult vertebrate brains, including the hippocampus. PolySia shows not only repulsive effects on NCAM-involved cell-cell interactions due to its bulky and hydrated properties, but also attractive effects on the interaction with neurologically active molecules, which exerts a reservoir function. Two different polysialyltransferases, ST8SIA2 and ST8SIA4, are involved in the synthesis of polySia chains; however, to date, the differences of the properties between polySia chains synthesized by these two enzymes remain unknown...

In 5000 BC, South American tribes digged the bones in the living head to seek ways to communicate with the gods, which was primitive trephination and may be the first neurosurgical behavior. In 2600 BC, Imhotep in ancient Egypt took the brain out of the head from the nose, for a better preserve of the mummy, which was a prototype of modern transsphenoidal surgery. And the development of anatomy in ancient Greek laid a solid foundation for neurosurgery. From 500 to 1500 AD, the rise of religion and the occurrence of war, prompted a large number of craniocerebral trauma, which contributed greatly to the early development of neurosurgery as a distinct specialty...

Neuroinflammation and increased oxidative stress are believed to contribute to the development of psychiatric diseases. Animal studies have implicated NADPH oxidases (NOX) as relevant sources of reactive oxygen species in the brain. We have analyzed the expression of NOX isoforms in post-mortem brain samples from patients with psychiatric disorders (schizophrenia, bipolar disorder) and non-psychiatric subjects. Two collections from the Stanley Medical Research Institute were studied: the Array Collection (RNA, 35 individuals per group), and a neuropathology consortium collection (paraffin-embedded sections, 15 individuals per group)...

The amygdala brain region has been implicated in the pathophysiology of schizophrenia through emotion processing. However, transcriptome messages in the amygdala of schizophrenia patients have not been well studied. We used RNA sequencing to investigate gene-expression profiling in the amygdala tissues, and identified 569 upregulated and 192 downregulated genes from 22 schizophrenia patients and 24 non-psychiatric controls. Gene functional enrichment analysis demonstrated that the downregulated genes were enriched in pathways such as 'synaptic transmission' and 'behavior', whereas the upregulated genes were significantly over-represented in gene ontology pathways such as 'immune response' and 'blood vessel development'...

The methionine-folate cycle-dependent one-carbon metabolism is implicated in the pathophysiology of schizophrenia. Since schizophrenia is a developmental disorder, we examined the effects that perturbation of the one-carbon metabolism during gestation has on mice progeny. Pregnant mice were administered methionine equivalent to double their daily intake during the last week of gestation. Their progeny (MET mice) exhibited schizophrenia-like social deficits, cognitive impairments and elevated stereotypy, decreased neurogenesis and synaptic plasticity, and abnormally reduced local excitatory synaptic connections in CA1 neurons...

BACKGROUND: Linguistic analysis of publicly available Twitter feeds have achieved success in differentiating individuals who self-disclose online as having schizophrenia from healthy controls. To date, limited efforts have included expert input to evaluate the authenticity of diagnostic self-disclosures. OBJECTIVE: This study aims to move from noisy self-reports of schizophrenia on social media to more accurate identification of diagnoses by exploring a human-machine partnered approach, wherein computational linguistic analysis of shared content is combined with clinical appraisals...

Pseudobulbar Affect (PBA) is a neurologic condition characterized by involuntary outbursts of crying and/or laughing disproportionate to patient mood or social context. Although an estimated 9% of nursing home residents have symptoms suggestive of PBA, they are not routinely screened. Our goal was to develop an electronic screening tool based upon characteristics common to nursing home residents with PBA identified through medical record data. Nursing home residents with PBA treated with dextromethorphan hydrobromide/quinidine sulfate (n = 140) were compared to age-, gender-, and dementia-diagnosis-matched controls without PBA or treatment (n = 140)...

OBJECTIVE: Suicide is a major concern for those afflicted by schizophrenia. Identifying patients at the highest risk for future suicide attempts remains a complex problem for psychiatric interventions. Machine learning models allow for the integration of many risk factors in order to build an algorithm that predicts which patients are likely to attempt suicide. Currently it is unclear how to integrate previously identified risk factors into a clinically relevant predictive tool to estimate the probability of a patient with schizophrenia for attempting suicide...
