Abstract

With a high rate of morbidity and mortality, colorectal cancer (CRC) ranks third in mortality among cancers. By analyzing the texture properties of images and quantifying the heterogeneity of tumors, radiomics and radiogenomics are non-invasive methods to determine the biological properties of CRC. Recently, several articles have discussed the application of radiomics in different aspects of CRC. Therefore, given the large amount of data published, this review aims to discuss how radiomics can be used for distinguishing benign and malignant colorectal lesions, diagnosing, staging, predicting prognosis and treatment response, and predicting lymph node and hepatic metastasis of CRC, based on radiomic features extracted from magnetic resonance imaging (MRI), computed tomography (CT), esophageal ultrasonography (EUS), and positron emission tomography-CT (PET-CT). Challenges in bringing radiomics to clinical application and future solutions have also been discussed. With the progress made in radiomics and the application of deep and machine learning in this area, radiomics can become one of the main tools for the personalized management of CRC patients shortly.

Abstract

Background and Purpose: The importance of hospital quality services in order to best utiliz available resources are not unknown to managers. This is especially important in the maternity sector due to the high density of referrals. Implementation of LDR (Labor, Delivery, Recovery) is one of the new approaches to improve delivery services in the country. The purpose of this study was to evaluate the effectiveness of LDR system on quality of delivery services in two selected hospitals of Qom. Methods and Materials: This is a descriptive-survey study. Data were collected with a cross-sectional approach to compare the quality of service indicators of a hospital with LDR system as a case and a hospital without LDR system as a control group. Data were collected using a standard questionnaire by Poisson sampling and analyzed by SPSS software. Results: There was no significant difference between the two hospitals except for LDR implementation. There was no significant association between LDR implementation in delivery sector with overall quality of service indicators (3 vs. 2.5) , input, process and output quality indices. However, LDR implementation had a significant effect on some items of these indices (level of significance = 0.05). Conclusion: According to the research findings, implementation of LDR did not have a significant effect on overall quality of services, but it did affect the subscales of these indices. Therefore, it seems clear that there is a need for proper management policy to control the costs involved in implementing this system.
