Early Maladjustment Schemas in Individuals with and without Type 2 Diabetes Mellitus

Objective. This study explored Early Maladjustment Schemas (EMSs) among individuals with and without type 2 diabetes mellitus and examined potential moderating roles for gender, level of education, and occupation. Methods. The sample included 371 adult participants (120 patients with diabetes and 251 individuals without diabetes), from Shiraz City, Fars province; Iran. The Young Schema Questionnaire-Short Form (YSQ-SF) was used to assess early maladjustment schemas. Results. Findings showed that patients with type 2 diabetes had significantly higher scores than controls on a number of EMSs, including abandonment, failure, vulnerability, enmeshment, self-sacrifice, entitlement, and insufficient self-control schemas as well as the over-vigilance and inhibition schematic domains. However, results did not support roles for gender, the level of education, and occupation on any of EMSs and schematic domains. Conclusions. Medical and health professionals may find these results helpful for assessment, treatment, and prevention goals in patients with type 2 diabetes

The effectiveness of cognitive behavioral therapy on treatment-resistant depression

BACKGROUND: Treatment-resistant depression (TRD) is a severe and chronic form of major depression. It poses significant clinical, personal, and economic burden and does not respond to antidepressants. Psychotherapy can be a suggested option. The aim of this study was to survey the effectiveness of cognitive behavioral therapy (CBT) on patients with TRD.METHODS: The present study was a quasi-experimental study with pretest, posttest, and follow-up. The statistical population included patients with TRD in Rafsanjan City, Iran, in 2018. 30 subjects were randomly selected and placed into experimental and control groups. Data were collected by Beck Depression Inventory (BDI), Rumination Questionnaire, and Brunel Mood Scale (BRUMS). To analyze data, multivariate analysis of covariance (MANCOVA) was used with SPSS software.RESULTS: CBT led to reducing depression and rumination and improving mood and this outcome was better than control group (P < 0.05).CONCLUSION: TRD is a chronic and disabling disorder that little research has been done about its treatment. CBT can be a good treatment offer for TRD

The origins of individual differences in skilled reaching for food in rats

x, 241 leaves : ill., ; 29 cmRats display considerable individual differences in performance of skilled reaching for food. Such variability in the normal performance of the rats intrudes upon the interpretation of many different experimental investigations in behavioral neuroscience. Understanding the origins of individual differences in skilled reaching performance of the rat provides insights into brain function, the evolution of skilled reaching, and also it helps optimizing preventative and therapeutic care. Although variability in skilled reaching is manifested in many studies, their origins remain poorly understood. The objective of the present thesis was to document the individual differences in skilled reaching for food in rats and to examine potential sources of individual differences in brain function. The present studies revealed that the difference in reaching success displayed by rats was a robust and constant feature in different conditions, emerged with practice and the motor cortex plays an important role in such variabilit

How Deep is Your Art: An Experimental Study on the Limits of Artistic Understanding in a Single-Task, Single-Modality Neural Network

Computational modeling of artwork meaning is complex and difficult. This is because art interpretation is multidimensional and highly subjective. This paper experimentally investigated the degree to which a state-of-the-art Deep Convolutional Neural Network (DCNN), a popular Machine Learning approach, can correctly distinguish modern conceptual art work into the galleries devised by art curators. Two hypotheses were proposed to state that the DCNN model uses Exhibited Properties for classification, like shape and color, but not Non-Exhibited Properties, such as historical context and artist intention. The two hypotheses were experimentally validated using a methodology designed for this purpose. VGG-11 DCNN pre-trained on ImageNet dataset and discriminatively fine-tuned was trained on handcrafted datasets designed from real-world conceptual photography galleries. Experimental results supported the two hypotheses showing that the DCNN model ignores Non-Exhibited Properties and uses only Exhibited Properties for artwork classification. This work points to current DCNN limitations, which should be addressed by future DNN models

Simethicone for the Preparation before Esophagogastroduodenoscopy

Aim. The presence of air bubbles and foam in stomach and duodenum is a common problem during esophagogastroduodenoscopy (EGD). Methods. Candidates of elective EGD received 40 mg chewable tablet of simethicone (n = 90) or placebo (n = 83), with 30 mL water, 15–30 min before the EGD. Foam/air bubbles during endoscopy were assessed and graded on a 4-point scale, and patients' satisfaction with the endoscopy was scored from 0 to 10. Results. The amount of gastric but not duodenal foam/air bubbles was significantly lower in the simethicone group compared with the placebo group (P = 0.002). Duration of endoscopy was, on average, one minute shorter in the simethicone group compared with the placebo group (P < 0.001). Patients' satisfaction with the procedure was the same in the two groups. Conclusion. Administration of simethicone prior to EGD reduces the amount of gastric foam and bubbles and provides better visibility for evaluating the mucosa. It also decreases the duration of endoscopy. Further trials are required to find the final effect of the drug on diagnosis of pathological lesions

Immediate results and six-month outcomes after percutaneous coronary intervention in a referral heart center in Isfahan, Iran

BACKGROUND: There is a lack of data in our society on the outcomes, complications, and prognostic factors in patients with coronary artery disease who underwent percutaneous coronary intervention (PCI). We evaluated the success rate, early and late outcomes, and prognostic factors in a referral university center in Isfahan, IRAN. &nbsp;&nbsp; METHODS: This prospective cohort study was conducted in Chamran University Hospital in Isfahan (IRAN) from March 2010 to February 2011. Patients consequently were included if they have the indication for emergent or elective PCI. Outcomes included procedural success, complications, and major adverse cardiovascular events (MACE) during hospitalization and 6 months follow-up. &nbsp;&nbsp; RESULTS: A total of 282 patients (74.1% females) with mean age of 57.0&plusmn;3.2 years were studied. Most of the patients (89.7%) underwent elective PCI. Angiographic and procedure success rates were 95.7% and 94.6%, respectively. In-hospital MACE included two cases of death (0.7%) and one MI (0.3%); 2/29 (6.9%) of the emergent PCI and 1/253 (0.4%) of the elective PCI cases. MACE during follow-up included three cases of death (1.0%) and two MI (0.7%); 2/252 (0.8%) of the elective PCI and 1/28 (3.5%) of the emergent PCI cases. The overall MACE was calculated as 8 cases (2.8%) which included 5/29 (17.2%) of the emergent and 3/253 (1.1%) of the elective cases; P &lt; 0.001. In multivariate analysis, none of the factors including gender, age, emergency of the procedure, lesion type, number of stenotic vessels, or stent type were associated with total MACE (P &gt; 0.05). &nbsp;&nbsp; CONCLUSION: PCI is performed with an acceptable success rate in our center in Isfahan and mortality and complications are within the range reported by other highly specialized centers in IRAN. Further studies with larger sample size are needed to find predictive factors.Keywords: Percutaneous coronary intervention, Myocardial infarction, Acute coronary syndrome, Reperfusion therapy, Outcome, Mortality.</p
