Abstract

Background and Aim: Randomized controlled clinical trial is the most valid type of epidemiological studies for the treatment of diseases. The aim of the present article is to determine the subject area, type of intervention, and blinding methods used in this type of study design.

Materials and Methods: This is a cross-sectional descriptive study in which all the articles based on randomized controlled clinical trial were studied. The articles were all affiliated to Tehran University of Medical Sciences(TUMS) and indexed in PubMed by the end of the year 2010.

Results: Among the subject areas, most randomized controlled clinical trials(44 cases or 14%) were conducted in the field of Obstetrics and Gynecology. In terms of intervention type, the majority of the studied trials(214 cases or 68.2%) used drug intervention. And regarding the type of blinding, double-blinding was employed more than other blinding techniques(152 cases or 48.4%). On the whole, 125 cases(39.8%) of randomized controlled clinical trials were conducted through drug intervention simultaneous with double-blinding technique.

Conclusion: In different subject areas, the application of blinding techniques and type of intervention are somewhat related to research methodology and medical ethics. It seems that intervention type depends on subject area, and blinding technique is determined by the selected type of intervention.

Abstract

 Background and Aim: Isoflurane is one of the selective and mostly-used respiratory anesthetic materials in the field of neurosurgery. Studies have shown that temporary rise in the level of liver enzymes may occur after anesthesia by halogenic ethers and hence cause liver lesions. The aim of this study was to investigate the effects of isoflurane on the activity of ALT-AST-ALP-GGT enzymes as an indicator of liver function.

 Materials and Methods: This study was performed on a sample of 40 patients who were under neurosurgery without any liver disease in Milad Hospital of Tehran. The patients' blood samples were collected before, 24, and 72 hours after anesthesia. The enzymes activities was assessed by spectrophotometric method.

 Results: Insignificant changes before and after anesthesia were seen in the activity of ALP, and AST enzymes. The level of ALT enzyme has a significant rise, 72 (P=0/022) and 24 (P=0/014) hours after anesthesia in comparison with before anesthesia. The level of GGT enzyme in comparison to its past has significant rise 72 hours after anesthesia (P=0/002). The level of this enzyme showed a significant difference 24, and 72 hours after anesthesia (P=0/041).

 Conclusion: The significant changes seen in the levels of ALT, GGT enzymes in three different periods of time might be as a result of possible liver parenchymal and cholestatic damage caused by using Isoflurane or other drugs such as Midazolam which effects liver function. It seems the assessment of the levels of these enzymes can provide useful information for probable subsequent actions.

Abstract

Background and Aim: In today's challenging world, the ethical issues of work as a requirement in organizations have always been discussed and its relevance to organizational citizenship behavior as a kind of antitrust behavior has always been raised. The aim of this study was to determine the relationship between organizational citizenship behavior and work ethic among the staffs of the faculties of Tehran university of medical sciences in 2016-2017.
Materials and Methods: The present research was descriptive-analytic and the statistical population of the study was 426 employees of colleges. They were selected according to the Cochran formula as proportional sample and selected by random sampling. Organizational citizenship behavior inventory (1988) and Grigory, et al, Patty (1990) questionnaire, whose validity was assessed by the experts. The cronbach's alpha coefficient, organizational citizenship behavior inventory (0.793), and job ethics (0.764), represent the internal consistency of the questionnaire. For analysis of variables, descriptive statistics and spearman correlation test were used and kolmogorov-smirnov test was used to normalize the data.
Results: Most male respondents, aged between 20-30 years; in terms of graduate degrees, were in a professional contract with a record of 5-10 years. Results showed that there was a positive and significant relationship between organizational citizenship behavior and work ethics (p=0.783).
Conclusions: Higher organizational citizenship behavior leads to higher levels of work ethics. Therefore, by training and strengthening organizational citizenship behavior, the level of work ethics among employees can be improved.

Abstract

Background and Aim: Knee ligament rupture is a common knee injury, especially among athletes. Considering the importance of treatment quality in the affected population, there is a crucial need for the collection of high-quality, standardized national-level data. This can be achieved by establishing a Minimum Data Set (MDS). The present study aimed to design a Minimum Data Set for the Knee Ligament Rupture Reconstruction Registry System in Athletes.
Materials and Methods: This applied research was conducted in 2024 using a quantitative method (descriptive-comparative and Delphi technique) across three phases. In the first phase, using a descriptive-comparative approach, the required data elements from the national registry systems of selected countries (Norway, Sweden, Denmark, UK) were extracted and analyzed in comparative tables. In the second phase, the data elements currently recorded for patients undergoing knee ligament rupture reconstruction surgery in Iran were identified using a descriptive data collection form. In the third phase, based on the findings from the first two phases, a preliminary MDS was designed as a questionnaire. Its validity was then assessed over two rounds using the Delphi method by a panel of experts (24 in the first round, 18 in the second). Finally, items that achieved a consensus of 75% or higher were included in the final MDS.
Results: In the review conducted on the registry systems of selected countries, including Norway, Sweden, Denmark, and England, the data elements recorded in these systems were first extracted. Subsequently, in the first phase of the study, the extracted data elements were categorized into two main categories: Administrative and clinical. The findings of this phase were obtained through their comparison in comparative tables. The findings of the second phase of the study consisted of data elements extracted from the medical records of patients who had undergone knee ligament rupture reconstruction surgery in Iran. In the third phase of the study, the final minimum data set for patients undergoing knee ligament rupture reconstruction surgery was developed based on the findings of the first and second phases of the study as well as expert opinions. This data set comprised 78 data elements organized into two sections: administrative (9 data elements) and clinical (69 data elements). In the administrative section, data classes were categorized into demographic, socioeconomic, and visit-related groups. In the clinical section, data classes were categorized into diagnostic, anthropometric, surgical, follow-up, and outcome groups.
Conclusion: The Minimum Data Set for knee ligament rupture reconstruction surgery can play a significant role in collecting high-quality data, evaluating and managing treatment quality and outcomes, and informing planning and policymaking in this field by ensuring the collection of integrated and high-quality data.
