Muscle inflammation or myositis is a general description of chronic and progressive inflammation involving muscles. The aim of this study was to investigate the effect of eight weeks of increased training with marjoram supplementation on muscle inflammatory indices in healthy rats.

In this study, 27 rats of about two months (200-250 g) were randomly divided into three groups: control, endurance training and endurance training + marjoram. They got rat were kept in groups of 9 in conditions of free access to water and food. The treadmill endurance training program was performed for eight weeks, five days a week, without slope, and for the first to third week of each session for 40 minutes, and in the eighth week for 60 minutes. Marjoram supplement was given to the rat in the supplement group using a mixture of water. Findings were analyzed spss at the significance level (p = 0.05).

The results showed that there was a significant difference between the three groups in the amount of TNFα, IL-6, CK. The results of Tukey post hoc test showed that the rate of inflammatory markers after exercise without supplementation increased significantly, which was significantly lower in the endurance + marjoram group than the control group. Also, the results showed that there was a difference between the endurance and endurance training groups with marjoram and the control group.

Increased endurance training with marjoram consumption probably increases the total oxidative capacity.

Infection prevention is a basic issue in the dental profession and the transmission of infectious diseases is an important issue in dentistry. The present study was performed to evaluate the risk of infection transmission by students in the restorative department of the School of Dentistry using the Six Sigma model.

This cross-sectional study was performed in the first three months of 2016. The subjects of the study consisted of 265 dentistry students in the restorative department of the dental school, 30 of whom were randomly selected as the sample. Data were collected using a standard checklist. Using the fish bone diagram, the causes and the most important defects were identified and the Six Sigma model was used to analyze the quality of the process.

Fifty-nine defects were detected in the restorative department. The most important defects which were identified as the first three factors, respectively, were: the lack of skills, experience and education of dental students in infection control, not washing of hands by dentists before wearing latex gloves, and not pressing the water and air poar for 15 seconds before use for each patient.

The results of the study showed that knowledge of students about infection control is insufficient and there is a need for more education with strict supervision in this field.

Waiting time is one of the factors affecting patients' satisfaction with the quality of services, therefore, reducing the waiting time has an essential role in the improvement of services and clients' satisfaction. The present study was performed to study the client patients waiting time in referral restorative dentistry department of dental clinic using Six Sigma model.

In this descriptive study, 300 patients who referred to the restorative dentistry department of dental clinic, were included. Finally, 30 subjects were selected using random sampling method. Data were collected by waiting time measurement forms and researcher-made checklists. To determine the process quality, six sigma model was used. Finally, data were analyzed using SPSS version 16.

The highest mean waiting time belonged to the oral diseases department (mean=31 min) and the lowest one belonged to the examination unit of restorative dentistry department (mean=15 min). The most important factors extending the waiting time were simultaneous entrance of patients (mean=4.6 min), lack of medical students' skill and experience (mean=4.2 min), lack of employees and integration of reception unit with cash desk (mean=4 min), respectively.  

Therefore, by analyzing reception process, appropriate management, and using Six Sigma model, waiting time will reduce, clients' satisfaction will increase, and the quality of services will improve.

Sharp rise in health care costs associated with the reduction of hospital's support by government has increased the importance of insurance organizations as the main source of hospital's income. An important part of hospitals’ demands is related to the medical records of Iranian Health Insurance organization that are subject to deductions and are deduced from the hospitals’ demands after investigating the cause of defect in the process.
The present study was conducted as a retrospective descriptive research. In this study, sampling was not conducted and all incomplete files of patients covered by Iranian Health Insurance Organization in the reference hospital (n=30) were entered into the study. Data of checklists were entered into Excel software version 22 and the causes were determined by using Fishbone diagram. Six-sigma scale was used to analyze the quality of the process.
Process errors were detected in 6 groups and the highest error rates were respectively related to pharmaceutical orders control stages, entering them in cards and requesting drug through drug delivering system. The quality of the reviewed process was evaluated as moderate level based on the calculated sigma. The highest rate of error was related to the records of patients covered by rural fund of non-global services.
Measures such as staff training, monitoring and updating the record keeping system and improving external parts coordination can greatly reduce errors in three above-mentioned stages.
