No full textSchizophrenia and Dental Health: A Systematic Review
No full textABSTRACT: Schizophrenia is characterized not only by psychopathological symptoms but also by medical comorbidities. Among the latter, there are limited data on dental health. We conducted a systematic review with the primary aim of clarifying the extent of the relationship between dental diseases and schizophrenia. The second aim was to delineate an intervention program based on illness-related factors that influence dental health. The preferred reporting items for systematic reviews and meta-analyses statement for reporting systematic reviews was used. Only articles published in English language peer-reviewed journals were considered; we excluded case reports, meta-analyses, and systematic reviews, as well as studies that did not clearly report statistical analysis, diagnostic criteria, or the number of patients included. Twenty-one studies comprising 13,110 patients with schizophrenia and 9025 healthy controls were included. Negative symptomatology, long duration of illness, smoking habit, drug-induced xerostomia, and neuroinflammation are the most critical areas. We suggest an intervention program for prevention and treatment of dental diseases in schizophrenia

Gas-Phase Photocatalytic Coprocessing of CO2 – H2O(v) to Energy Products Promoted by the n,n-Junction In2O3@g-C3N4 under VIS-Light
Get PDFCarbon dioxide capture and utilization is a strategic technology for moving away from fossil-C. The conversion of CO2 into fuels demands energy and hydrogen that cannot be sourced from fossil-C. Co-processing of CO2 and water under solar irradiation will have a key role in the long-term for carbon-recycling and energy products production. This article discusses the synthesis, characterization and application of the two-phase composite photocatalyst, In2O3@g-C3N4, formed by thermal condensation of melamine in the presence of indium(III)nitrate. The composite exhibits a n,n-heterojunction between two n-type semiconductors, g-C3N4 and In2O3, leading to a more efficient charge separation. The composite has a flat band potential enabling it to effectively catalyze the reduction of CO2 in the gas phase to produce CO, CH4 and CH3OH. While the composite‘s overall photocatalytic efficiency is comparable to that of neat g-C3N4, its ability to promote multielectron-transfer and Proton Coupled to Electron Transfer (PCET) suggests that there is a potential for further optimization of its properties. The use of labelled 13CO2 has allowed us to clearly exclude that the reduced species are derived from the photocatalyst decomposition or the degradation of contaminants
Emerging methods for fabricating functional structures by patterning and assembling engineered nanocrystals
No full textInorganic nanocrystals and nanoparticles have aroused increasing attention in the last years due to their original optoelectronic, thermodynamic, mechanical and catalytic properties, which are extremely attractive for fundamental understanding as well as for their huge potential in applications. The ability to strongly exploit the original potential of such nano-objects and access their properties relies on the ability to bridge the gap between the nanoscopic and mesoscopic scale. Indeed, to integrate nanoparticles in structures, materials and finally devices, their incorporation in processable systems, and their organization in morphologically controlled assembly and/or ordered arrays is crucial. The fabrication of 2/3 D patterned micro- and nanostructure is a promising strategy for integrating the nanoparticles in macroscopic entities in order to properly exploit their unprecedented functionality for biomedical, electronic, catalytic materials and devices. In this paper, different and complementary strategies able to engineer inorganic colloidal nanocrystals due to their organization in original functional materials and structures will be described
First-admissions in Psychiatry: a cluster analysis of a sample of inpatients from 2019 to 2021
No full textIntroduction: Only a few studies analyse the clinical and psychopathological characteristics of first-admitted inpatients regardless of diagnosis.
Objectives: Describing the psychopathological, demographic, and clinical characteristics of inpatients with acute symptomatology identifying groups with common features using factors extracted from the Brief Psychiatric Rating Scale (BPRS).
Methods: We selected 103 (48 F) inpatients from the psychiatric ward of the Sant’Andrea Hospital in Rome from January 2019 to December 2021. We assessed psychopathological characteristics and suicide risk with BPRS, Global Assessment of Functioning, and Columbia-Suicide Severity Rating Scale and gathered the anamnestic and demographic data. We conducted descriptive analyses and factor analysis on BPRS items. Then we used the BPRS factors as variables to perform a cluster analysis.
Results: Major Depressive Disorder (MDD) was the most frequent diagnosis. We obtained five factors: “Psychotic dimensions” (FI); “Anxiety” (FII); “Hostility and lack of cooperation” (FIII); “Depression” (FIV); “Flattening of affectivity” (FV). We identified two clusters (cluster 1 n=31; cluster 2 n=72). Patients in cluster 1 reported higher average scores in FI and FIII while the average scores of cluster 2 patients in FII and FIV were higher than patients in cluster 1. We called cluster 1 “psychotic and hostile patients compulsory admitted with a low risk of suicide”. Cluster 2 patients are “affective patients with a high risk of suicide”. The two clusters share an average age of 38-39 yo and an average GAF score indicating severe impairment and inability to function in almost all areas. They differ in the psychiatric diagnosis represented: respectively, Schizophrenia Spectrum Disorder and Bipolar Disorder with low suicidal risk, MDD, and Personality Disorders with a high suicidal risk. 39% of patients in cluster 1 were involuntarily admitted.
Conclusions: The results of our study show that patients admitted for the first time usually are admitted for psychotic symptoms and a high risk of suicide. Psychotic patients more often show hostility and lack of cooperativeness which can explain the higher rate of involuntary admissions. Patients with predominant affective symptoms show a higher risk of suicide. Our analyses do not consider categorical diagnosis highlighting that exist transdiagnostic groups of patients with specific needs
A woman lost in the cemetery: A case of time-limited amnesia
No full textA 43-year-old woman one day experienced a dissociative fugue which she could not recall. She was married, nulliparous, with no history of dissociative disorder or other psychiatric disorders. She had been sexually abused during late childhood-early adolescence. She was examined thoroughly from both psychiatric and medical standpoints to exclude organic causes for her condition. Magnetic Resonance Imaging showed only some non-specific abnormalities. On personality tests, a histrionic structure of personality emerged, with obsessive and narcissistic traits accompanied by rigidity and anxiety, dysphoria and high risk for depression; some impairment was found in executive function tests. Final diagnosis was one of dissociative fugue. In fact, organic traits were not sufficient to establish a diagnosis of Transient Global Amnesia. © 2010 Psychology Press
