Background and Objectives: In this regard, in addition to reducing exposure, the most effective way to prevent hepatitis B is vaccination. The coverage of hepatitis B vaccination in the Iranian Health Personnel is reportedly different in various studies and there is not an overall estimate of it. Therefore, the present study was conducted to determine the immune response to hepatitis B vaccine among Iranian Health Personnel using the meta-analysis method.

Methods: This study was a systematic review of the Iranian databases, including Magiran, Iran Medex, IRANDOC, SID, MEDLIB and international databases, including Scopus, PubMed, ScienceDirect and the Google Scholar search engine without any time limit to 2015 using standard Persian and English keywords. Searches were conducted by two researchers independently. Meta-analysis was performed using STATA, version 11.1 to combine data through Random Effects Model.

Results: We evaluated 6311 subjects in 21 studies. The history of injection and complete coverage of hepatitis B vaccination in the Health Personnel was 86.9% (CI: 95%, 83-90.7) and 70.3% (CI: 95%, 65.6-75), respectively. The minimum and maximum vaccination coverage were related to the North (52.7%) and West of Iran (87.2%), respectively.

Conclusion: The coverage of hepatitis B vaccination in Iranian Health Personnel is less than European countries, which requires new management strategies and policies to maximize hepatitis B vaccination in high risk professional groups.

Background and Objectives: Regular blood transfusions in patients with hereditary hemolytic anemia, especially thalassemia, increase the survival of most patients but also may result in infection with viruses like hepatitis. In order to identify these diseases and other complications in people with thalassemia, this study aimed to investigate epidemiological and clinical findings in patients with thalassemia in Dezful in 2015.
Methods: In this descriptive-analytic study, data were collected from medical records in Dezful thalassemia Clinic by the census method. The collected data included gender, age, location, ethnicity, blood type, transfused blood type, time between blood transfusions, medications, vaccinations, underlying diseases, and operations and their time.
Results: The records of 174 thalassemia patients with a mean age of 23.60 years were evaluated. Of these, 23 patients (13.2%) had thalassemia intermediate and 151 (86.8%) had thalassemia major. The last mean serum ferritin was 2760.60. Independent T test showed a significant relationship between the type of thalassemia and age at diagnosis (P=0.000). There was a significant positive correlation between age and blood transfusion intervals so that the intervals increased with age (P=0.004) (r=0.21).
Conclusion: The high mean age in the center compared to other studies as well as the low frequency of side effects indicate the effectiveness of new treatments and increased survival of these patients.

Background and Objectives: The presence of biological aerosols in the air of medical centers is more than other enclosed spaces. Determining the role and importance of such factors has always attracted the attention of health and medical researchers. This study aimed to evaluate the bacterial density of surgical and infectious wards in two important hospitals of Kermanshah and environmental factors affecting them.
Methods: In this study, a total of 160 samples were selected. One hundred and twenty eight samples were related to the air of surgical and infectious wards in two stages before and after disinfection of wards and 32 samples were related to the hospital outdoor air as the control sample. MCS Flite (SKC) air sampling pump was equipped with a Biostage 225 (SKC) microbial sampling cassette made in the USA. Data were analyzed with SPSS 19.
Results: The highest bacterial density in the air was measured in Imam Khomeini Hospital (402.7± 200.3 CFU/m3) and the lowest was in Imam Reza Hospital (258.6 ± 90.5 CFU/m3). There was a significant inverse relationship between air temperature and total bacterial density and a significant direct relationship between the whole population and bacterial density.
Conclusion: It seems that reduced bacterial density in wards’ air with increased temperature occurs due to increasing the air volume and replacing air in wards. The presence of people in the ward plays an important role in increased bacterial density.
