The efficacy of religious training (prayer) on the improvement of the schizophrenic patients’ quality of life at Sina Psychiatric Hospital (Bakhtiari Province, 2011)

Abstract Background: Schizophrenia is a chronic illness which is one of the major health problems worldwide; therefore, selecting diverse treatment methods congruent with community culture is of particular importance. The purpose of this study was to investigate the effect of religious training on the improvement of schizophrenic inpatients’ quality of life. Materials and Methods: In this interventional study, 62 schizophrenic inpatients were randomly assigned to two groups: Experimental and control. Schizophrenia Quality of Life Scale (SQLS) was administered to both groups. The experimental group went through religious training (prayer and Quran histories) for two months. Then the two groups took the SQLS again, and the data were analyzed through dependent t-test using SPSS software. Results: The results showed that before the intervention, there were not any significant differences between the two groups (P=0.08). However, after the intervention, a significant difference was observed in the mean score in the experimental group (P=0.04), whereas there was not a significant difference in the control group mean score over this period (P= 0.14). Conclusion: The findings of this study showed that religious and spiritual training can be effective in improving schizophrenic patients’ satisfaction with their quality of lif

Development and validation of a metacognitive-cognitive-behavioral model for explaining trichotillomania

Background & Aims: Trichotillomania (TTM) is an unknown disorder and resistant to treatment. The purpose of this study was to develop and validate the new metacognitive-cognitive-behavioral model for trichotillomania. Methods: The present study was a description and correlation study. In this study, 635 participants (304 male and 331 female) were selected. The participants completed the Massachusetts general hospital hair pulling scale (MGH-HPS), dysfunctional attitude scale (DAS), cognitive distortion scale (CDS), automatic thought questionnaire (ATQ), metacognition questionnaire (MCQ), and the obsessive-compulsive behavior scale (OCBS). For reliability assessment of the factor structure of the metacognitive-cognitive-behavioral model, the structural equation modeling analysis was used by AMOS software. Results: The results of the structural equation modeling supported a metacognitive-cognitive-behavioral model for trichotillomania. Moreover, the results showed that the model had the best fit to the data and was closely related to the theoretical assumptions. Conclusion: The model presented in this study illustrates a multidimensional approach that focuses on the metacognitive, cognitive, and behavioral dimensions; hence, the model presented in this study is a new explanatory model. This model may prompt future research into trichotillomania and facilitate clinical treatment and case formulation. © 2014, Kerman University of Medical Sciences. All rights reserved

Validation of a Classification System for Obsessive-Compulsive and Related Disorders Based on DSM-5

The purpose of this study was to examine whether a broad obsessive-compulsive and related disorders model, which consisted of obsessive-compulsive, hoarding disorder, body dysmorphic, trichotillomania and pathological skin picking, displayed sufficient data fit. On the other hand, we examined whether a reduced obsessive-compulsive and related disorders symptoms model consisting of above mentioned disorders demonstrated superior fit or not. To test the factor structure validity of the classification system of obsessive-compulsive spectrum disorders, we used Confirmatory Factor Analyses (CFA). Result of factor structure analysis revealed and supported an OCSD symptoms dimension that included obsessive-compulsive, hoarding disorder, body dysmorphic, trichotillomania, and pathological skin picking symptoms. Also, results of this study supported the DSM-5 changes

Develop and Validate a Metacognitive-Cognitive-Behavioral Model for Body Dysmorphic Disorder

The purpose of this study was to develop and validate a metacognitive-cognitive-behavioral model for body dysmorphic disorder. A sample of 800 participants (400 males and 400 females) was selected randomly and questionnaires were administered to them. Structure analysis was used to test the factor structure validity of the metacognitive-cognitive-behavioral model for body dysmorphic disorder. Results of the structure analysis revealed and supported a metacognitive-cognitivebehavioral model for body dysmorphic disorder. Also, the results showed that the model had the best fit to the data and was closely related to the theoretical assumptions. The model presented in this study illustrates a multidimensional approach that the model focuses on the metacognitivecognitive-behavioral dimensions; hence, the model presented in this study is a new explanatory model. The model may prompt future research into body dysmorphic disorder and facilitate clinical treatment and case formulation

Body image and meta-worry as mediators of body dysmorphic disorder

Objectives: Meta-worry and attitudes towards the body have been largely overlooked as potential risk factors for body dysmorphic disorder (BDD) despite theorizing that a negative body image may play a critical role in the development of this disorder. Participants: The purpose of this study was to evaluate the fit of a theoretical model specifying body image and meta-worry as mediators between cognitive, metacognitive beliefs and body dysmorphic disorder(BDD) in a nonclinical sample of 635 participants (304 male and 331 female). Results: The data supported the model, and meta-worry and body image significantly mediated the relationship between cognitive, metacognitive beliefs and BDD. These findings provide essential preliminary evidence that body image may represent a necessary but not sufficient risk factor for BDD and that treatment for BDD should consider targeting body-related pathology in addition to meta-worry. Conclusion: The model may prompt future research into body dysmorphic disorder

Investigation of wedge water-entry under symmetric impact loads by experimental tests

One of the main challenges for engineers in designing high-speed crafts is the evaluation of hydrodynamic loads during the impact of hull to wave’s surface. This paper presents an experimental investigation on the pressure distribution on three wedge-sections with 15°, 20° and 30° deadrise during water-entry. Assessment of pressure distribution on the effects of parameters such as drop heights, deadrise angles and the weights of the models had done. Time histories of impact pressure were recorded. It was showed that, the maximum pressure for 20° wedge had increased 2.4 times in comparison with 30° wedge while this number is 1.23 time for the 15° wedge. But the effects of weight and drop height were not as much as deadrise angle. The results give an appropriate approximation of the maximum pressures by the model resembling high-speed craft’s hull sections, which can be used to estimate impact loads in different operational condition. The condition of water level during the impact process has also been observed in each test. The nature of impact test with non-constant speed can clarify the real behavior of falling objects, which can be assumed as the significance of current study

Quantitative Cytotoxicity, Cellular Uptake and Radioprotection Effect of Cerium Oxide Nanoparticles in MRC-5 Normal Cells and MCF-7 Cancerous Cells

Optimal distribution of cerium oxide nanoparticles (CONPs) or nanoceria can have a significant impact on their cytotoxicity, cellular uptake, and radioprotection effects. In this study, two different distribution plans of CONPs were investigated. A scanner electron microscope (SEM) was used for chemical analysis and recording of CONP images. Using MTT assay, the non-toxic concentrations of nanoceria with two different distribution plans were determined in MRC-5 and MCF-7 cell lines. Nanoceria cellular uptake at 50, 150, and 250 μM with two different dispersion plans was determined by using the UV/VIS absorbance of cell culture medium after 24 h of incubation. In order to quantify radioprotection effect, cells treated with non-toxic concentrations of nanoceria were exposed to 10, 40, and 100 cGy of 6 MV photon beams. The diameter of the spherical CONPs was 29 nm. Energy dispersive spectroscopy analysis showed that the cerium element has the highest weight percentage in CONPs (97.9). Accumulation rate of filtered and non-filtered suspension were determined as 0.3608 and 14.2708 μg/ml/h, respectively. The 70 and 110 μM concentration of sustained nanoceria suspension did not have any toxicity for MRC-5 and MCF-7 cells, respectively. In both cell lines, 50, 150, and 250 μM of filtered nanoceria had a significant uptake than the non-filtered nanoceria. A total of results showed that the 70 μM of nanoceria have a significant radioprotection on normal cells in the radiation dose of 40 and 100 cGy, while the highest cellular uptake of nanoceria occurred in cancer cells. The results suggest that using of stable distribution of CONPs for radiation protection could be a good choice, knowing that these nanostructures will have selective protection in normal cells. © 2018, Springer Science+Business Media, LLC, part of Springer Nature

Results of a single-arm pilot study of 32P microparticles in unresectable locally advanced pancreatic adenocarcinoma with gemcitabine/nab-paclitaxel or FOLFIRINOX chemotherapy.

BACKGROUND: Unresectable locally advanced pancreatic cancer (LAPC) is generally managed with chemotherapy or chemoradiotherapy, but prognosis is poor with a median survival of ∼13 months (or up to 19 months in some studies). We assessed a novel brachytherapy device, using phosphorous-32 (32P) microparticles, combined with standard-of-care chemotherapy. PATIENTS AND METHODS: In this international, multicentre, single-arm, open-label pilot study, adult patients with histologically or cytologically proven unresectable LAPC received 32P microparticles, via endoscopic ultrasound-guided fine-needle implantation, planned for week 4 of 5-fluorouracil, leucovorin, irinotecan and oxaliplatin (FOLFIRINOX) or gemcitabine/nab-paclitaxel chemotherapy, per investigator's choice. The primary endpoint was safety and tolerability measured using Common Terminology Criteria for Adverse Events version 4.0. The lead efficacy endpoint was local disease control rate at 16 weeks. RESULTS: Fifty patients were enrolled and received chemotherapy [intention-to-treat (ITT) population]. Forty-two patients received 32P microparticle implantation [per protocol (PP) population]. A total of 1102 treatment-emergent adverse events (TEAEs) were reported in the ITT/safety population (956 PP), of which 167 (139 PP) were grade ≥3. In the PP population, 41 TEAEs in 16 (38.1%) patients were possibly or probably related to 32P microparticles or implantation procedure, including 8 grade ≥3 in 3 (7.1%) patients, compared with 609 TEAEs in 42 (100%) patients attributed to chemotherapy, including 67 grade ≥3 in 28 patients (66.7%). The local disease control rate at 16 weeks was 82.0% (95% confidence interval: 68.6% to 90.9%) (ITT) and 90.5% (95% confidence interval: 77.4% to 97.3%) (PP). Tumour volume, carbohydrate antigen 19-9 levels, and metabolic tumour response at week 12 improved significantly. Ten patients (20.0% ITT; 23.8% PP) had surgical resection and median overall survival was 15.2 and 15.5 months for ITT and PP populations, respectively. CONCLUSIONS: Endoscopic ultrasound-guided 32P microparticle implantation has an acceptable safety profile. This study also suggests clinically relevant benefits of combining 32P microparticles with standard-of-care systemic chemotherapy for patients with unresectable LAPC
