Effect of vitamin D3 supplement in glycemic control of pediatrics with type 1 diabetes mellitus and vitamin D deficiency

Background: Glycemic control prevents microvascular complications in patients with type I diabetes mellitus such as retinopathy, nephropathy and neuropathy that influences quality of life. Some studies show the immunomodulatory effect of vitamin D in synthesis and secretion of insulin. Aims: In this study we evaluate glycemic changes after vitamin D3 supplement in children with type I diabetes mellitus and vitamin D deficiency. Materials and Methods: In children with type I diabetes mellitus, level of vitamin D and HbA1C was measured. Patients with type I diabetes mellitus who had vitamin D deficiency (25OHD 9.9. This supplement transfer patients toward better glycemic control for the entire group (p-value < 0.0001). Conclusion: Vitamin D3 supplement improves HbA1C in pediatrics with type I diabetes mellitus and vitamin D deficiency. © 2015, Journal of Clinical and Diagnostic Research. All Rights Reserved

Understanding destination brand love using machine learning and content analysis method

This study aims to apply the concept of brand love in tourist destinations in order to identify the core-elements that could have influential impacts on generating destination brand love. This has been carried out by using a mixed-method of machine learning and content analysis. We have discovered that the topics have been generated for historical landmarks and destinations by analyzing the visitors’ on-line reviews are architecture, historical sites, tradition and shrine places, which could be similar to other tourist historical destinations in different part of the world. However, this study has the potential to be a model for other researches related to different destinations with possible different topics emerged. Our study contributes by providing both researchers and managers a novel method to understand what attributes of destination brand love they need to posit more emphasize to attract more visitors based on the destination type

Optimized superpixel and AdaBoost classifier for human thermal face recognition

Infrared spectrum-based human recognition systems offer straightforward and robust solutions for achieving an excellent performance in uncontrolled illumination. In this paper, a human thermal face recognition model is proposed. The model consists of four main steps. Firstly, the grey wolf optimization algorithm is used to find optimal superpixel parameters of the quick-shift segmentation method. Then, segmentation-based fractal texture analysis algorithm is used for extracting features and the rough set-based methods are used to select the most discriminative features. Finally, the AdaBoost classifier is employed for the classification process. For evaluating our proposed approach, thermal images from the Terravic Facial infrared dataset were used. The experimental results showed that the proposed approach achieved (1) reasonable segmentation results for the indoor and outdoor thermal images, (2) accuracy of the segmented images better than the non-segmented ones, and (3) the entropy-based feature selection method obtained the best classification accuracy. Generally, the classification accuracy of the proposed model reached to 99% which is better than some of the related work with around 5%

Utility of Urine N-acetyl-β-D-glucosaminidase for Prediction of Renal Damage in Obese Children

The incidence of obesity has increased globally in children and adults. In addition, renal dysfunction is an important complication of childhood obesity. This study was performed to identify the diagnostic value of N-acetyl-β-D-glucosaminidase (NAG), a renal injury marker, for the early determination of renal damage in childhood obesity. Totally, 115 obese children and 115 healthy normal weight controls were enrolled in a cross-sectional case�control study. Urine NAG was measured in sample urine and normalized by urine creatinine (CR). In addition, correlation of urine NAG with other variables such as blood pressure (BP), blood glucose, and urine albumin was evaluated. Mean systolic BP (P <0.001), serum glucose (P = 0.047), urine albumin/Cr (P = 0.049), and urine NAG/Cr (P = 0.037) were significantly higher in obese children, compared with normal healthy controls. There was no correlation between urine NAG and urine albumin excretion. Urinary NAG/Cr was a simple and safe screening test for early determination of renal damage in children with obesity. © 2021 Saudi Center for Organ Transplantation

Evaluation of libido in post hysterectomy patients

Background: Hysterectomy is a common surgery as treatment for chronic and benign gynecologic problems. Eeach year more than half million women in USA undergo hysterectomy. Methods: This analytical cross-sectional study, was done on 100 women who had underwent hysterectomy at least two years before the study; and met inclusion criteria of study. During interview, the questionnaire were completed, then examination was done by gynecologist. Most of the information were collected from the patient’s files. Results: In this study the most indication of hysterectomy was fibroma and the most common type surgery was total abdominal hysterectomy, and mostly were done without oophorectomy. 20% of cases were without or weak prior to operation and 80% with medium (or high) libido, after hysterectomy the figures changed to 41% and 59% respectively. After hysterectomy libido with P=0.001, frequency of coitus with P=0.001, and sexual satisfaction with P=0.013, significantly declined. Libido after hysterectomy declined with aging (P=0.01). There was no significant correlation between oophorectomy and libido. Conclusion: Sexual function declines significantly after hysterectomy, with no association with oophorectomy and type of surgery

Development of an Occupational Cognitive Failure Questionnaire (OCFQ): Evaluation Validity and Reliability

Background and aims: Accident investigation show that more than 90 percent of accidents cause by human errors. Human errors are also due to cognitive failures. Cognitive failures can be defined as cognitive-based errors on simple tasks that a person is normally able to complete without fault; such mistakes include problems with memory, attention or action. The present study was designed to develop a measurement tool for the estimation of cognitive failures in industrial workplaces. Methods: In the present analytical-descriptive study, an Occupational Cognitive Failure Questionnaire (OCFQ) was developed. For the evaluation of validity, internal consistency and repeatability of the OCFQ the content validity, Cronbach α coefficient and test-retest methods were used, respectively.   Results: A draft of 35-items questionnaire was created and following the evaluation of validity, five items were rejected. The new measuring instrument with 30-items was developed. The CVI for the final OCFQ was found to be acceptable (CVI=0.7). Results showed that the final OCFQ was internally consistent (α=0.96) and repeatable (ICC =0.996 and P<0.001). Conclusion: For measurement of cognitive failure in industrial workplaces, a valid and reliable instrument is required. Based on the obtained results, it can be concluded that the developed questionnaire (OCFQ) is a valid and reliable tool for the estimation of cognitive failures in industrial workplaces

Penetrating aortic atherosclerotic ulcer complicated by periesophageal hematoma.

Penetrating aortic atherosclerotic ulcers have been recently recognized as an entity among the acute aortic syndromes with a potentially fatal outcome. We describe the case of a patient presenting with severe chest pain who died as a result of a thoracic-aorta penetrating atherosclerotic ulcer complicated by a intramural hematoma of the esophagus and stomach, leading to exsanguination. To our knowledge this is the first case reported in the literature of such a complication from penetrating aortic atherosclerotic ulcers
