Abstract

 Background and Aim: Along with the constant increase in world population and consequently, the growing need to provide cellulose, as the most abundant organic substance in nature to produce cellulose products, concerns regarding the possible contamination of these products might cause skin, and genital and urinary infections. The aim of this study is to determine the possible microbial contamination of these products supplied in the city of Tehran.

 Materials and Methods: This is a descriptive study on 200 samples of unexpired cellulose products including napkins, nappies, sanitary napkin, and cardboard boxes to carry sweets. Fifty samples were obtained in the city of Tehran during six months from September 2011 to February 2012. Microbial contamination was investigated according to the procedure proposed by the Institute of Standards and Industrial Research of Iran.

 Results: The results obtained indicate that 18 samples (9%) exceeded the level allowed for aerobic bacteria and molds in one gram of specimens. Besides, 16 samples (8%) were contaminated with at least one of the following bacteria: Streptococcus Group D, Staphylococcus aureus, Pseudomonas aeruginosa and Escherichia coli. A total of 34 samples (17%) could not be consumed. The least and the most contaminated products were sanitary napkins (0.5%) and cardboard boxes to carry sweets (5%), respectively.

 Conclusion: The presence of pathogenic bacteria in cellulose products that could cause skin, and genital and urinary tract infections asks for more control over such sanitary products.

Abstract

Background and Aim: Vegetables are one of the major components of food basket and consumption of them is on the rise. On the other hand, diseases and outbreaks caused by this group of foodstuffs have increasing trend. This study was performed to investigate the microbial contamination of vegetables used in south of Tehran.

Materials and Methods: Hundred fresh packaged and non packaged vegetable samples composed of 10 kinds, were examined based on the methods presented in Iran national standards. For each sample, enumeration of enterococcus and total microbial count was carried out by the pour plate technique in KF agar and plate count agar, respectively. Escherichia coli detection was also performed using lauryl sulfate broth, EC broth, peptone water and MacConkey agar mediums. Biochemical tests namely urea hydrolysis, motility, sulfide hydrogen (SH2) production, gas production and sugar fermentation were conducted as conformational tests of Escherichia coli.

Results: All (100%) of mixed leafy vegetables, spinaches, peppers, kuku (Persian food) vegetables, wheat sprouts and mung been sprouts had contamination higher than acceptable limits. In the case of green onions, basils, kuku vegetables, mushrooms and broccolis, respectively 40, 60, 30, 90 and 30 % of the samples were in contravention with acceptable limits, in terms of at least one parameter.

Conclusion: Our results show that consumption of vegetables specially those used as raw, need more attention at washing point and need to use hygienic rules of health department and health care centers, at shopping and consumption steps.

Volume 16, Issue 4 (Oct 2022)
Abstract
Background and Aim: Reforming the structure of medical universities and its continuous adaptation to the mission of the organization and new functions is an undeniable necessity. The purpose of this article was to explain how to implement this policy.
Materials and Methods: The current qualitative study was conducted in 2020 retrospectively based on Kingdon’s multiple streams model. Data collection was done using two methods: individual interviews and document review. Sampling of the managers and experts of the administrative development and transformation centers of the Ministry of Health and 12 universities of Medical Sciences as well as vice-chancellors of the universities was done in a purposeful and snowball method until data saturation was reached by conducting 19 individual interviews. Data analysis were done with framework and content analysis methods, and using MAXQDA 2020 software.
Results: The low of structural problems included quantitative and qualitative changes in new tasks in the environmental units of universities, interference and parallel work in the tasks of university units, and bargainings for restructuring by universities. The policy low included the obligation to make structural changes in the upstream laws and documents, including the Fifth Development Plan, and the cooperation of all stakeholders. The political process included the implementation of the Health Transformation and the Family Physician Plan, and the support of relevant policymakers and the approval of the law of becoming a university trustee in the law of the fifth plan of economic development and also gaining the all-round support of the stakeholders.
Conclusion: The medical sciences universities, as the headquarters arm of the Ministry of Health at the provincial level, need to have flexible structure in line with the needs of their surrounding units. In luential context factors in policy-making the reform of the structure of the headquarters of universities/colleges, in addition to the stream of structural problems, the main of which was the change in the duties of the units, along with the political determination created in the Ministry of Health, led to the simultaneous occurrence of three streams of problems, Politics and politics and finally opening the window of opportunity and changing the structure and organization of the headquarters of medical sciences universities.

Abstract
Background and Aim: this study aims investigating the effect of the physician's presence on the error of recording surgical codes by surgical assistants and the resulting financial effects in Rasoul Akram hospital.
Materials and Methods: The present study was a descriptive-analytical and prospective study that was performed by collecting data in the hospital and reviewing the documents from Jun to March 2022. Therefore, in order to compare the deductions according to the presence or absence of the doctor, an expert was stationed in the operating room to enter the information in special forms, and thus the types of deductions for each of the mentioned situations were identified. T-test was used for analysis between the two groups (presence and absence of physician) and data were analyzed using Excel and SPSS software.
Results: Three hundred and one records were reviewed during the presence of the physician and 300 cases during the absence of the physician based on Cochran sampling formula. The percent difference between hidden deductions in the presence and absence of the physician was not significant (P-value=0.078). However, the difference between the obvious deductions in the presence and absence of the physicians was significant (P-value=0.024). The difference in obvious deduction costs was significant in the presence or absence of a physician (P-value<0.001). But, the difference in hidden fraction costs in the presence or absence of physicians, was not significant (P-value=0.435).
Conclusion: The presence or absence of a surgeon has an effect on the amount of errors in the registration of surgical codes by the surgeon’s assistant and, as a result, this matter affects the percentage and costs of surgical deductions, especially in the obvious deductions. Therefore, planning for the presence of the surgeon in cases where the error of registering the codes by the surgeon’s assistant leads to obvious deductions, can help to more accurate documentation and, as a result, fewer deductions are accrued.
