The aim was to detect CCHF virus (CCHFV) among wild ticks from Artiodactyla, Bos taurus, Ovis aries, and Capra hircus, in a previously declared CCHFV-free province of Kohgiluyeh Boyer-Ahmad, southwest Iran. Methods: From April to November 2015, hard ticks were collected in a cross-sectional study and checked by microscope for species identity from ungulates in 51 study villages. About 55% of the ticks were then subjected to reverse-transcription polymerase chain reaction (RT-PCR) to detect CCHFV genome. Results: Overall, 859 hard ticks were captured, from which 8 different species in two genera were identified. The genus Rhipicephalus was distributed in half (#26) of the study villages. It was the most frequent (≈60%) tick genus. Hyalomma anatolicum, H. asiaticum, H. excavatum, H. marginatum, H. scupense, Rhipicephalus sanguineus, R. turanicus, and R. bursa were identified on the ruminants. From 469 adult ticks subjected to RT-PCR, one (0.2%) tick, R. bursa, was positive with CCHFV genome. It was from a cold hardy highland village in Dena County. It had CCHFV RNA for the first time from this region. Conclusion: The detection of CCHF viral RNA in one hard tick species, R. bursa, was confirmed in the southwest of Iran, thus partially indicating CCHFV presence of ticks in this region.}, keywords = {Tick,Crimean-Congo Hemorrhagic Fever,Rhipicephalus,Hyalomma,Iran}, url = {https://jhsss.sums.ac.ir/article_46327.html}, eprint = {https://jhsss.sums.ac.ir/article_46327_0082d578351509376191cf6071ffe9bf.pdf} } @article { author = {Abbasi, Alireza and Yosefinejad, Saeed and Bahrami, Shima and Hoseini, Mohamad}, title = {Catalytic oxidation of carbon monoxide from vented gas space heaters using alumina foam supported CuMnOx Nanocatalyst}, journal = {Journal of Health Sciences & Surveillance System}, volume = {7}, number = {2}, pages = {60-66}, year = {2019}, publisher = {Shiraz University Of Medical Sciences}, issn = {2345-2218}, eissn = {2345-3893}, doi = {10.30476/jhsss.2020.84882.1047}, abstract = {Introduction: Carbon monoxide (CO) is an odorless, tasteless, colorless, and nonirritating poisonous gas, recognized as the silent killer for the 21st century. It is produced during partial combustion of carbon-containing compounds. Improper ventilation and flue installation of vented gas space heaters cause carbon monoxide gas to penetrate the building, leading to many deaths annually. The catalytic oxidation of CO has received great attention due to its applications in different fields. In this study, alumina foam coated by CuMnOx catalyst was used to remove CO from the vented gas space heaters. Method: This is a full-scale experimental study on the outflow from vented gas space heaters. Alumina foam supported hopcalite (CuMnOx) catalyst was synthesized using a co-precipitation method for CO oxidation from THE vented gas space heaters. The XRD and SEM were used to characterize the synthesized catalyst. The concentration of CO was measured by IMR 1500 combustion gas analyzer. Result:  The particle size of the catalyst was in the range of 200-600 nm. XRD showed different crystallizations, and the crystal size was in the range of 20 -120 nm.  There was no significant CO removal in the case of using uncoated alumina foam. Results showed CuMnOx catalyst significantly increased the CO removal. The removal efficiencies were 83% and 89% in heating powers of 2300 and 3200 kcal/hr, respectively. The average CO conversation rate was approximately 60.45 µg/gr.min. Conclusion: CuMnOx coated on alumina has a significant effect on CO removal from the vented gas space heaters. The catalyst and outlet gas temperature were the most important factors affecting CO removal. }, keywords = {Carbon monoxide,hopcalite,Air Pollution,Indoor}, url = {https://jhsss.sums.ac.ir/article_46328.html}, eprint = {https://jhsss.sums.ac.ir/article_46328_bf7c2a0e1cc42d4c9411dbe411911b4a.pdf} } @article { author = {Kalantari, Reza and Zamanian, Zahra and Kamrani, Mehrdad and Bakhshi, Ehsan and Rostami, Matin and Mortazavi Mehrizi, Morteza and Nazari far, Ebrahim}, title = {The relationship between mental workload and work-related musculoskeletal symptoms in different working groups in a hospital}, journal = {Journal of Health Sciences & Surveillance System}, volume = {7}, number = {2}, pages = {67-72}, year = {2019}, publisher = {Shiraz University Of Medical Sciences}, issn = {2345-2218}, eissn = {2345-3893}, doi = {10.30476/jhsss.2020.84973.1048}, abstract = {Background: Mental workloadis the operator´s mind effort, the excessive levels of which can endanger his/her health.

The present study aims to investigate the onset of VD symptoms and their effects on the job performance of the elementary school teachers. Methods: This cross-sectional, descriptive-analytical study was conducted on 121 male and female elementary school teachers in Mobarakeh County during the academic year 2018-2019. Data were collected using a researcher-made questionnaire. In doing so, the researchers talked to 10 people composed of qualified experts in occupational health, ergonomics, and health education and a number of teachers about how to design the questions as well as the answer  scale for each section. Results: In the present study, the prevalence of VD was higher among female teachers (41%) compared to male ones (20%). That is to say, the prevalence of the VD symptoms in female teachers was more than twice that of the male teachers. The study results demonstrated a significant relationship between having a silent resting place and coughing (p=0.028). Accordingly, the prevalence of the symptoms of cough was significantly higher in the teachers who did not have a silent resting place in comparison to those who benefitted from a quiet resting place. Conclusion: Thus, it is recommended that safety, occupational health, and ergonomic programs should be designed for teachers at the Ministry of Education in collaboration with concerned specialists.

These protozoa have been isolated from many sources in Iran. This study was undertaken to determine the diseases due to these parasites in the south of Iran. Methods: In this cross-sectional study, 200 cerebrospinal fluid (CSF) samples and 15 corneal scrapings were collected from patients admitted in clinics of Shiraz city. The samples were examined by light microscopy, cultivation and molecular methods. Phylogenetic relationship was also conducted among the sequences and various Acanthamoeba spp. based on nucleotide sequences in NCBI GenBank. Results: No infection in CSF samples was seen, while one patient suspected with keratitis was positive to Acanthamoeba sp. infection only by PCR. Using Sequencing technique and Phylogenetic tree, the genotype of the parasite was demonstrated T4. This sample belonged to a 26 year old woman who used a contact lens. Conclusion: Our results indicate that it is necessary to pay attention to the complexity of the free living amoeba infections, especially in soft contact lens wearers. Also, PCR as an appropriate method in diagnosis is recommended for the detection of free living amoebae.

Applying molecular markers has been common for identification of taxa, so that suitable marker choice representing high divergence is a crucial issue to reveal taxonomic status of the taxa in this approach. Methods: In this analytical study, the performance of two mitochondrial markers including cytochrome c oxidase subunit I (COI) and cytochrome b (cyt b)was compared with nuclear recombination activating protein I locus(RAGI), and their efficiency in identification of mammal taxa as the host of zoonotic diseases was evaluated. The COI, cyt b, and RAGI sequences were retrieved from GenBank. Intra-and interspecific genetic distances were estimated and compared at the species level. The variances in genetic divergence were also calculated and compared between the markers.  Results: Our results showed a wide gap between intra-and interspecific genetic distances for both COI and cyt b markers and less apparent gap for RAGI, indicating that this nuclear marker is less proper for species delimitation in DNA barcoding. Conclusion: We concluded that in the case of multiple sequences available COI, contributes to accurate differentiation at the species level, showing a significant gap between intra-and interspecific genetic distances and may play an important role as DNA barcoding marker.}, keywords = {Mammals,Species delimitation,DNA barcoding,Genetic divergence}, url = {https://jhsss.sums.ac.ir/article_46333.html}, eprint = {https://jhsss.sums.ac.ir/article_46333_8ca72cc838e6ec001e3268aef78c99c3.pdf} } @article { author = {Mousavi-Shirazi-Fard, Zahra and mazloom, zohreh and Jalali, Mohammad and Asmarian, Naeimehossadat and Dabbaghmanesh, Mohammad Hossein and Panahiyan, Mahmood}, title = {Comparison of the effects of individualized medical nutrition therapy and consistent carbohydrate meal-planning on glycemic control, energy, and carbohydrate and protein intake in hospitalized diabetic patients: A randomized clinical trial study}, journal = {Journal of Health Sciences & Surveillance System}, volume = {7}, number = {2}, pages = {94-99}, year = {2019}, publisher = {Shiraz University Of Medical Sciences}, issn = {2345-2218}, eissn = {2345-3893}, doi = {10.30476/jhsss.2020.85081.1055}, abstract = {Objective: Individualized Medical Nutrition Therapy (IMNT) is recommended as a part of glycemic control in hospitalized diabetic patients.
