Background: The prevalence of infections among general population can affect the prevalence among blood donors. Due to to the importance of blood safety, this study was conducted to estimate the prevalence of HIV, HBV, and HCV in donated bloods in Iran in 2018.Methods: Using information of 1,308,284 blood donors, we designed this cross-sectional study to estimate the prevalence of transfusion-transmitted infections (TTIs) in Iranian blood donors. All the prevalence was reported per 100,000 population.Results: HIV prevalence in blood donors was about 2 per 100,000 (95% CI: 1.999, 2.001) population. Prevalence of HBV and HCV was 53(95% CI: 52.999-53.00) and 26 (95% CI: 25.999-26.001), respectively.Conclusion: It seems that the screening of volunteers would defer many people who may have been infected with TTIs; as a result, people with the least risk of being infected are selected to donate blood. Notice: All of these infected bloods were detected and discarded from the blood donation chain.

Background: The classroom is an important part of the educational environment, which should meet the standard requirements including safety and adequate spaces regarding the number of learners, color, lighting, noise, proper equipment, and air conditioning. This study aimed to investigate the safety level of classrooms in Shiraz University of Medical Sciences. Methods: This cross-sectional study was conducted in Shiraz University of Medical Sciences (SUMS) classrooms (n = 63), in the south-west of Iran. Data regarding the safety measures were collected using an audit checklist. Finally, an index called Classroom Safety Requirement Index (CSRI) was introduced in order to calculate percentage of safety measures in the classrooms. Results: The results revealed that the ‘environmental condition’ dimension of the CSRI was in a good level. The ‘building’, ‘equipment’ and ‘electrical’ dimensions were in the medium level, and the ‘fire safety and emergency’ dimension was placed in the poor level. 38.70% of the classes (24 classes) were in the Standard Occupant Load (SOL or degree of overcrowding) and others (61.30% of classrooms) were overcrowded (unacceptable occupant load). Conclusion: The examined classrooms were very poor regarding the ‘fire safety’ and ‘emergency exit’, which requires proper and appropriate measures to improve safety in these areas.

Background: Most workers are exposed to a variety of hazards in their workplace. Devising a comprehensive checklist and developing an index for Occupational Safety and Health (OSH) assessment could be useful. This study was conducted in a heavy automotive company with the aim of developing and validating an OSH assessment index.Methods and Materials: We used the experiences and comments of OSH experts to devise a checklist for OSH assessment. Weighting various harmful factors was done using Analytical Hierarchy Process (AHP) technique. Intra-class Correlation Coefficient (ICC) was applied to measure the reliability of the checklist (SPSS version 20). In the studied industry, 150 workstations were assessed using the developed comprehensive checklist. In order to validate the total index, we assessed its correlation with 4 groups of occupational statistics (i.e. accident frequency, severity rates, lost working time rate, and occupational disease incidence rate). A p value of < 0.05 was considered significant.Results: Among 7 sub-indices, sub-indexes of occupational health and the workplace order (w=0.21) and housekeeping (w=0.04) had the highest and the lowest AHP weights, respectively. The mean of ICC was found to be 0.978. The total index (OSHITotal) and the Accident Severity Rate (ASR) had a strong inverse significant correlation (r = -0.774, P=0.002).Conclusion: The developed index covered important occupational hazards. The inter-evaluator reliability for this index was high.

Objectives: This study aimed to investigate the extent of implementation of safety measures in 14 student housings in one of the largest universities in Fars province, Shiraz, Iran.Method: A cross-sectional study was conducted in 14 student housings of one of the largest universities, located in Shiraz, Iran. Audit checklists were completed and rated thought field inspection and interview. Safety Requirement Index (SRI) was then used to evaluate the safety of student housings. SRI was graded on five scales (0-19%: very poor (unsafe); 20-39%: poor (relatively unsafe); 40-59%: moderate; 60-79%: good (relatively safe): and 80-100%: excellent (safe). Results: The mean SRI score was 71.01±15.46%. The highest and lowest level of SRI was 94.11±6.60% for dimensions of public health (and 47.70±18.42% for elevator safety.Conclusion: None of the studied housings was completely safe in all dimensions. Most of the studied housings were categorized as safe in the dimensions of public health and ventilation and air-conditioning systems; relatively safe in the dimensions of electrical, building, fire and kitchen safety; and moderate in the elevator safety and emergency response. Establishment of safety management system is necessary to promote safety in the studied housings. The results of this study indicated the need to inform the authorities about the safety priorities in housings, to promote the safety conditions. The results could also be used to raise awareness regarding their role and responsibilities about the safety of housings.
