Recent Advances in Alkaline Exchange Membrane Water Electrolysis and Electrode Manufacturing.

Water electrolysis to obtain hydrogen in combination with intermittent renewable energy resources is an emerging sustainable alternative to fossil fuels. Among the available electrolyzer technologies, anion exchange membrane water electrolysis (AEMWE) has been paid much attention because of its advantageous behavior compared to other more traditional approaches such as solid oxide electrolyzer cells, and alkaline or proton exchange membrane water electrolyzers. Recently, very promising results have been obtained in the AEMWE technology. This review paper is focused on recent advances in membrane electrode assembly components, paying particular attention to the preparation methods for catalyst coated on gas diffusion layers, which has not been previously reported in the literature for this type of electrolyzers. The most successful methodologies utilized for the preparation of catalysts, including co-precipitation, electrodeposition, sol-gel, hydrothermal, chemical vapor deposition, atomic layer deposition, ion beam sputtering, and magnetron sputtering deposition techniques, have been detailed. Besides a description of these procedures, in this review, we also present a critical appraisal of the efficiency of the water electrolysis carried out with cells fitted with electrodes prepared with these procedures. Based on this analysis, a critical comparison of cell performance is carried out, and future prospects and expected developments of the AEMWE are discussed.

Revisiting the concept of severe mental illness: severity indicators and healthcare spending in psychotic, depressive and dissociative disorders.

Background: The concept of severe mental illness (SMI) has been related to bipolar or psychotic diagnosis, or to some cases of depressive disorders. Other mental health problems such as personality disorders or posttraumatic dissociative conditions, which can sometimes lead to relevant functional impairments, remain separate from the SMI construct.Aims: This study aimed to evaluate the clinical severity as well as healthcare spending on dissociative disorders (DDs). This diagnostic group was compared with two other groups usually considered as causing severe impairment and high healthcare spending: bipolar and psychotic disorders, and unipolar depression.Methods: From a random sample of 200 psychiatric outpatients, 108 with unipolar depression (N = 45), psychotic/bipolar (N = 31) or DDs (N = 32) were selected for this study. The three groups were compared by the severity of their disorder and healthcare indicators.Results: Of the three groups, those with a DD were more prone to and showed higher indices of suicide, self-injury, emergency consultations, as well as psychotropic drug use. This group ranked just below psychotic/bipolar patients in the amount of psychiatric hospitalisations.Conclusions: Despite a certain intra-professional stigma regarding DDs, these data supported the severity of these posttraumatic conditions, and their inclusion in the construct of SMI.

Cognitive Remediation Interventions in Schizoaffective Disorder: A Systematic Review.

Background: Patients with schizoaffective disorder (SAD) suffer from cognitive impairment, which negatively influences their functionality. Cognitive remediation (CR) interventions have been shown to be effective in patients with schizophrenia (SZ) and bipolar disorder (BD), but evidence in SAD is limited so far. The aim of this study is to systematically review the published data on CR interventions, either in neurocognition or social cognition, in patients with SAD. Methods: We conducted a comprehensive, computerized literature search using terms related to CR interventions in psychotic and affective disorders, and particularly in SAD. Pubmed, Embase, and Web of Knowledge databases were used up to February 28th, 2018 according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. The search returned 2672 articles of which four were finally selected meeting the inclusion criteria. Results: Cognitive Enhancement Therapy, computerized Cognitive Remediation Therapy and Cognitive Training showed positive results in subsamples of patients with SAD regarding neurocognition and functioning in comparable terms to patients with schizophrenia as well as in a greater extent in quality of life. Benefits in social cognition were also described when Social Cognition Interaction Training was considered in patients with SAD. Conclusions: CR interventions seem to improve neurocognition and social cognition in patients with SAD as well as functioning and quality of life. However, further randomized controlled trials on CR interventions with an optimized design focusing on selected sample of patients with SAD are imperative.
