Background and Aim: Given the rising trend of ageing and the vulnerability of the aged group to diseases and health costs, it is important to determine the exposure of elderly households to the burdensome costs of health. Materials and Methods: The incidence and severity of elderly costs at provincial level and income quintiles were calculated; besides, chi-square test was used to determine th...
background & aims of the study: petrochemical industry is an important industry in the economic development of the country that causes employees have exposure with several kinds of contamination. the aim of this study was semi-quantitative assessment of the health risk of occupational exposure to chemical materials and investigation of spirometry indices between employees of petrochemical indus...
Introduction: Patients administered with a therapeutic dose of 131I for thyroid cancer treatment are potential sources of unacceptably high radiation exposure to other individuals, particularly the patient's immediate family members. The aim of this study is to investigate effects of early liothyronine consumption after radio-iodine therapy on accumulated dose and e...
Sulfur mustard is the most widely used chemical agent in the Iran-Iraq war .In a retrospective cohort study of 1337 soldiers with a history of sulfur mustard exposure, factors such as age, smoking habits, number of exposure episodes and the use of gas masks were determined, together with an assessment of their relationship with the occurrence of long-term pulmonary complications. The models sug...
Introduction: One of the most important threats for employees working in chemical industries is exposing to the chemical materials. Lack of precaution and control regulations during working with chemicals can have irreparable consequences. So, in order to achieve an effective control program, it is necessary to have an appropriate assessment of the procedures involving exposure to the chemica...
Background and purpose: In recent years the use of radioactive materials for diagnostic and therapeutic purposes grew rapidly in nuclear medicine. The imaging technicians and nursing staff in radiopharmaceutical centers are in close contact with patients. Therefore, they are exposed to different radiation levels. This study was done on risk assessment of staff exposed to 99mTc-MIBI Materials...
Malaria is considered as one of the most threatening diseases affecting peacekeeping forces serving in malaria endemic countries. The Jordanian Armed Forces participated in many of the United Nations peacekeeping missions in over 20 countries across the world. Thin and thick blood smears were collected from military personnel returning to Jordan, and relevant data including occupation, age, sex...
Background: The development of methods to alleviate radiation-induced health effects is important for the practical use of radiation therapy and for understanding the molecular mechanisms mediating these effects. Here, we examined the protective capability of N-acetylcysteine (NAC) on life-shortening effects induced by continuous low dose-rate gamma-ray exposure in mice. Materials and Methods: ...
Background & Aims of the Study: Petrochemical industry is an important industry in the economic development of the country that causes employees have exposure with several kinds of contamination. The aim of this study was Semi-quantitative assessment of the health risk of occupational exposure to chemical materials and investigation of spirometry in...
