Introduction: Ethical LIVING is a lifestyle in which all areas of human existence and work are formed and flow around ethics. That is, a person who wants to live morally, in all areas, tries to know the ethical considerations related to that area and follow them in practice and live according to them. The current article is research on the moral system of Thomas Aquinas with a focus on examining the nature of the moral goal of human life and the moral rationality of such a life. Material and Methods: The present review study examined bioethics from the perspective of Thomas Aquinas in a descriptive manner. In order to achieve this goal, articles related to research keywords from Thomson Information Institute, Science Direct and Pub Med were examined and books related to the views of Thomas Aquinas were studied. Conclusion: The results of this study show that according to Thomas Aquinas's view on man, becoming like God and realizing God's image in material life and seeing God in the hereafter is the moral goal and eternal happiness of man. Also, Thomas Aquinas believes in the moral rationality of such a life from both perspectives-having a reason to live morally and the usefulness of such a life.

Background: Outcomesforcystic fibrosis PATIENTS are improving rapidly. The demographic factors are notable variables inoutcomes, which can be evaluated and modified.Objectives: This study was designed to investigate the association between outcome and demographic factors in PATIENTS with cystic fibrosis.PATIENTS and Methods: This was a cross-sectional study and data were gathered for 331 PATIENTS using the census method, from March 2001 to September 2014 in Iran. Data was analyzed using logistic regression analysis, chi-square test, and independent sample t test using SPSS 18. Odds ratio with confidence intervals of 95% and P<0.05 were considered significant.Results: There were 85 (25.7%) deceased PATIENTS and 246 (74.3%) LIVING PATIENTS at the time of the study. Of the 246 LIVING CF PATIENTS, 202 (82.2%) were less than nine years of age, and 77 (90.6%) out of the 85 deceased CF PATIENTS had died younger than four years of age. There was a significant difference between outcome and location of residence. The risk of mortality was 50% less in urban PATIENTS than in rural PATIENTS (P=0.03). The risk of mortality was approximately two times higher in PATIENTS with a positive family history than in those with a negative family history (P=0.02). The proportion of mortality was approximately two times, or 94%, higher for those in a consanguineous marriage than for those in a non-consanguineous marriage (P=0.01).Conclusions: The results demonstrated that the mortality rate was higher in CF PATIENTS with a positive family history, a consanguineous marriage, and residence in a rural area. Therefore, demographic factors play an important role in the outcome of cystic fibrosis. Unfortunately, these parameters, which can be managed easily and with low cost, have been overlooked.

Background and Aim: The diagnosis of COVID-19 is an essential step toward controlling the pandemic. For this purpose, a series of laboratory methods have been developed. This study evaluated the efficiency of the ELISA method for COVID-19 IgM and IgG detection. Materials and Methods: In this case-control study, 46 blood samples from PCR positive COVID-19 PATIENTS and 49 samples from PCR negative COVID-19 subjects were collected. Subsequently, the presence of IgM and IgG in all blood samples was assessed using the Pishtaz Teb ELISA kit. Results: The data demonstrated that among 49 PCR negative, 40 (81. 6%) were IgM negative and 9 (19. 1%) were IgM positive. Besides, out of the 49 PCR-negative PATIENTS, 42 (85. 7%) and 7 (14. 3%) were IgG negative and positive, respectively. In 46 PCR-positive individuals, 40 (87%) were IgM negative, while 6 (13 %) were IgM positive. Of the 46 PCR-positive PATIENTS, 24 (52. 2%) were IgG negative, and 22(47. 8%) were IgG positive. Conclusion: Our results showed that detection of SARS-CoV-2 IgG and IgM using Pishtaz Teb ELISA kit is not enough for COVID diagnosis, but it can serve as a diagnostic RNA supplement to confirm infection with SARS-CoV-2 in approved clinics and other scientific communities, owing to its easy, rapid, and inexpensive availability.
