Exploration of radiographers' knowledge, attitudes, and practices in delivering healthcare to children with autism spectrum disorder.

INTRODUCTION: Autism Spectrum Disorder (ASD) poses unique challenges in healthcare settings, including radiographic examinations. This study aimed to assess the knowledge, attitudes, and practices (KAP) of radiographers in the United Arab Emirates (UAE) towards ASD children, a population with increased healthcare needs. METHODS: A cross-sectional survey was conducted online, targeting radiographers across the UAE. The instrument utilized was a comprehensive and validated self-administered questionnaire developed based on relevant literature. The questionnaire incorporated sections to gauge radiographers' knowledge about ASD, their attitudes towards working with ASD children, and their adherence to recommended practices during radiographic examinations. Descriptive and inferential statistics were employed to describe KAP and identify any influencing factors. RESULTS: Radiographers demonstrated a moderate level of knowledge regarding ASD. Despite the knowledge, misconceptions about ASD nature were common. The radiographers generally acknowledged the need for special care for ASD children during radiographic procedures. High confidence in working with ASD children was noted, particularly among older participants, despite a clear interest in further training. Good adherence to recommended practices was observed, with physical restraints not being a common practice. However, areas for improvement were identified, such as the use of visual aids. CONCLUSION: Despite a moderate level of knowledge and good practices, there is a need to improve UAE radiographers' understanding and handling of ASD children. IMPLICATIONS FOR PRACTICE: This study highlights the need for enhancing ASD-specific knowledge and training and integrating supportive tools in radiographic procedures. This comprehensive approach could significantly improve the radiographic service quality for ASD children in the UAE.

Incidence of hepatitis A and hepatitis E viruses and norovirus and rotavirus in fish and shrimp samples caught from the Persian Gulf / [Incidência de vírus da hepatite A e hepatite E e norovírus e rotavírus em amostras de peixes e camarões capturados no Golfo Pérsico]

Foodborne viruses including hepatitis A virus (HAV), norovirus (NoV), rotavirus (RoV) and hepatitis E virus (HEV) are easily transmitted through contaminated seafoods. The current research was done to assess the incidence of RoV, NoV GI and GII,hAV and hEV in fish and shrimp samples caught from the Persian Gulf, Iran. Three-hundred and twenty fish and shrimp samples were collected. The presence of foodborne viruses were assessed by the real-time PCR. Forty-nine out of 320 (15.31%) fish and shrimp samples were positive for foodborne viruses. Distribution of hAV, NoV GI and NoV GII amongst all studied samples were 0.93%, 5.93% and 8.43%, respectively. hEV and RoV viruses were not found in studied samples. Parastromateus niger and Scomberomorus commerson fish and Penaeus monodon shrimp were the most frequently contaminated samples. Simultaneous incidence of hAV and NoV GI and hAV and NoV GII were 0.31% and 0.93%, respectively. Distribution of foodborne viruses in samples collected through spring, summer, autumn and winter seasons were 14.28%, 9.33%, 11.76% and 24.44%, respectively. Findings revealed that the incidence of foodborne viruses was significantly associated with seafood species and also season of sampling.(AU)

Effects of ZnO nanoparticles in the Caspian roach (Rutilus rutilus caspicus).

Most studies investigating the toxicity of zinc oxide nanoparticles (ZnO NPs) focused on the effect of size, whereas exposure concentration and duration remained poorly understood. In this study, the effect of acute and sub-acute exposures of ZnO NPs on Zn compartmentalization and biomarkers' expression were investigated in Rutilus rutilus caspicus (Caspian roach) considering various exposure scenarios: i) the assessment of the concentration-response curves and median lethal concentration (LC50); ii) the assessment of the effects of organisms exposed at LC50 value and one tenth of LC50 value of ZnO NPs suspensions for 4 d and 28 d, respectively; iii) the assessment of 14 d depuration period. The same concentrations of ZnSO4 were investigated. The highest Zn accumulation was detected in gill after sub-acute exposure (4.8 mg/L; 28 d) followed by liver, kidney and muscle. In gill, liver and muscle, Zn from Zn NPs accumulated higher concentrations. Depuration (14 d) decreased Zn content in each organ, but no complete removal occurred except for muscle. Biomarkers' activity was significantly over expressed after treatments, but depuration brought back their values to background levels and most effects were related to acute concentrations (48 mg/L; 4 d) and in presence of ZnSO4. Histopathological analyses showed that the exposure to ZnO NPs increased lesions in gill, liver and kidney, with a direct proportionality between alterations and Zn accumulated in the target organs. After depuration, lesions regressed for both ZnO NPs and ZnSO4, but not in a complete way. These data could contribute to increase the knowledge about ZnO NPs risk assessment in aquatic vertebrates, suggesting that the size of ZnO NPs can influence biomarker and histopathological effects.

Enterotoxigenicity, distribution of enterotoxigenic genes and antibiotic resistance pattern of Staphylococcus aureus isolated from traditional sweet.

Resistant and enterotoxigenic Staphylococcus aureus strains are considered to be one of the major causes of foodborne diseases due to the consumption of sweet. The present research was done to study the distribution of enterotoxin types, enterotoxigenic genes and antibiotic resistance pattern of S. aureus strains isolated from traditional sweet samples. Eight-hundred and fifteen sweet samples were cultured and S. aureus strains were identified. Antibiotic resistance, enterotoxigenicity and enterotoxigenic gene profile were studied using disk diffusion, Enzyme Link Immunosorbent Assay and PCR, respectively. One-hundred and seven out of 815 (13.12%) sweet samples were positive for S. aureus. Prevalence of S. aureus in dried and semi-dried sweet samples were 15.08% and 11.13%, respectively (P <0.05). Forty-six out of 107 S. aureus strains (42.99%) were determined as enterotoxigenic. A (41.30%) and C (17.39%) were the most commonly detected enterotoxin types. Sea (20.56%), sec (14.95%) and seb (11.21%) were the most commonly detected enterotoxigenic genes. There were no positive sample for the sej enterotoxin gene. S. aureus strains harbored the highest prevalence of resistance against penicillin (88.78%), tetracycline (83.17%), ceftaroline (75.70%) and doxycycline (71.02%). Simultaneous presence of enterotoxins and enterotoxigenic genes in multi-drug resistant S. aureus strains indicates important public health issue regarding the consumption of contaminated traditional sweet samples.

VacA and cagA genotypes status and antimicrobial resistance properties of Helicobacter pylori strains isolated from meat products in Isfahan province, Iran.

Although Helicobacter pylori has a significant impact on the occurrence of severe clinical syndromes, its exact ways of transmission and origin have not been identified. According to the results of some previously published articles, foods with animal origins play a substantial role in the transmission of H. pylori to humans. The present investigation was carried out to study the vacuolating cytotoxin A (vacA) and cytotoxin associated gene A (cagA) genotypes status and antibiotic resistance properties of H. pylori strains recovered from minced-meat and hamburger samples. A total of 150 meat product samples were collected from supermarkets. All samples were cultured and the susceptive colonies were then subjected to nested-PCR, PCR-based genotyping and disk diffusion methods. 11 out of 150 samples (7.33%) were positive for H. pylori. All the isolates were further identified using the nested-PCR assay. Prevalence of H. pylori in hamburger and minced-meat samples was 1.42% and 12.5%, respectively. S1a, m1a and cagA were the most commonly detected genotypes. The most commonly detected combined genotypes in the H. pylori strains of minced-meat were s1am1a (10%), s1am1b (10%) and s2m1a (10%). Helicobacter pylori strains of meat products harbored the highest levels of resistance against ampicillin (90.90%), erythromycin (72.72%), amoxicillin (72.72%), trimethoprim (63.63%), tetracycline (63.63%), and clarithromycin (63.63%). Hamburger and minced-meat samples may be the sources of virulent and resistant strains of H. pylori. Meat products are possible sources of resistant and virulent strains of H. pylori similar to those vacA and cagA genotypes. Using healthy raw materials and observation of personal hygiene can reduce the risk of H. pylori in meat products.

Ginger extract and aerobic training reduces lipid profile in high-fat fed diet rats.

OBJECTIVE: Obesity, hyperglycemia and dyslipidemia, are major risk factors. However, natural therapies, dietary components, and physical activity may effect on these concerns. The aim of this study was to examine the effect of aerobic exercise and consumption of liquid ginger extract on lipid profile of Male rats with a high-fat fed diet. MATERIALS AND METHODS: 32 rats were randomly divided into 4 groups: 1) aerobic exercise, 2) Ginger extract, 3) combined aerobic exercise and Ginger extract, and 4) the control. Subjects of the first three groups received ginger extract via gavage feeding of 250 mg/kg. The exercise program was 3 sessions per week on 3 different days over 4 weeks. Total cholesterol (TC), Triglyceride (TG), HDL and LDL were measured 24-h before the first session and 24-h after the final training session. RESULTS: The concentration of TG in the control group was significantly higher than other groups. In addition, the mean concentration of TG in the aerobic exercise group was significantly lower than Ginger extract group but there was no significant difference as compared to combined aerobic exercise and ginger extract group. The combination of aerobic exercise and ginger consumption significantly reduced the TG level compared to ginger group. TC and LDL concentrations were significantly decreased in all groups compare to control. The combination of aerobic exercise and ginger extract feeding caused a significant increase in HDL levels. CONCLUSIONS: The finding of this study suggests that the combination of aerobic exercise and liquid ginger extract consumption might be an effective method of reducing lipid profiles, which will reduce the risk of cardiovascular diseases caused by high-fat diets.

The occurrence of ochratoxin A in rice in six provinces of Iran.

Three hundred and eight samples of rice purchased from retail markets in six different provinces in Iran from March 2012 to January 2013 were surveyed for the presence of ochratoxin A (OTA) using enzyme-linked immunosorbent assay. The recovery percentages of OTA from spiked rice samples at concentrations of 5 and 10 ng/g were found to be 85.3% and 86.7%, respectively. Analytical results showed a 9.4% frequency of contamination from total analyzed rice samples with a mean OTA level of 3.60 ± 2.66 ng/g. Concentrations of OTA in positive samples ranged from 0.84 ng/g to 11.37 ng/g, and in 17.3% of contaminated rice samples the concentrations exceeded the maximum tolerance limit set by European regulations for OTA in cereals (5 ng/g). Based on the results of this study, the estimated daily intake of OTA in rice was 0.62 ng/kg body weight/day for Iranian consumers.

Cadmium concentrations in shrimp (Penaeus semisulcatus and Penaeus monodon) caught from the coastal areas in Southern Iran.

This study was undertaken to determine the concentration of cadmium in two shrimp species, namely, Penaeus semisulcatus and Penaeus monodon caught from the coastal areas in southern Iran. Cadmium concentration was determined by graphite furnace atomic absorption spectrophotometry in 91 shrimp samples after nitric acid/perchloric acid digestion. Accuracy of the analysis was checked by various methods including the use of reference material. The mean ± SD of cadmium concentrations in shrimp samples were 0.128 ± 0.144 (µg/g). The cadmium concentrations ranged from 0.010 to 0.96 µg/g of the muscle tissues of shrimp. Higher cadmium concentration in shrimp samples was found in summer (significant p < 0.05). The results show that the mean concentration of cadmium in shrimp is lower than the maximum allowed levels according to International standards, although the concentration of cadmium in only one sample was more than the amount recommended by Food and Agriculture Organization. Therefore, no risk to the consumer arises from the cadmium contents of the shrimp caught in these areas.

Determination of mercury, cadmium and lead in human milk in Iran.

Breast milk contains both essential and nonessential trace elements. Mercury, cadmium and lead are nonessential, potentially toxic heavy metals with hematotoxic, neurotoxic and nephrotoxic properties even at very low concentrations. The objectives of this study were to determine the concentrations of mercury, cadmium and lead in the breast milk of healthy lactating women who were living in Isfahan, Iran. Concentrations of mercury, cadmium and lead were determined by graphite furnace atomic absorption spectrometry in 37 milk samples from healthy lactating women collected on first to sixth postpartum week. Accuracy of the analysis was checked by various methods including the use of reference material. The mean ± SD of the concentrations of mercury, cadmium and lead in human milk were 0.92 ± 0.54 µg/L (range 0.0-2.07 µg/L), 1.92 ± 1.04 µg/L (range 0.45-5.87 µg/L) and 7.11 ± 3.96 µg/L (range 3.06-19.47 µg/L), respectively. The results of this study showed that the concentrations of mercury, lead and cadmium in the milk samples from lactating women in Isfahan were high, which makes a major public health hazard for the inhabitants, especially neonatal and children, of the industrial locations. The results of the present study indicate a need for establishing safe intake values of heavy metals in human milk.

Effect of Ti-containing inclusions on the nucleation of acicular ferrite and mechanical properties of multipass weld metals.

In the present study, the influence of Ti-containing inclusions on the development of acicular ferrite microstructure and mechanical properties in the multipass weld metals has been studied. Shielded metal arc weld deposits were prepared by varying titanium content in the range of 0.003-0.021%. The variation in the titanium content was obtained by the addition of different amounts of titanium oxide nanoparticles to the electrode coating. The dispersion of titanium oxide nanoparticles, composition of inclusions, microstructural analysis, tensile properties and Charpy impact toughness were evaluated. As the amount of Ti-containing inclusions in the weld metal was increased, the microstructure of the weld metal was changed from the grain boundary allotriomorphic ferrite structure to acicular ferrite with the intragranular nucleation of ferrite on the Ti-containing inclusions, and the mechanical properties were improved. This improvement is attributable to the increased percentage of acicular ferrite due to the uniform dispersion of Ti-containing inclusions and the pinning force of oxide nanoparticles against the growth of allotriomorphic ferrite and Widmanstätten ferrite from the austenite grain boundaries.

Prevalence of hepatitis A virus in sea food in Iran / Prevalência de vírus da hepatite A em frutos do mar no Irã

The objective of this study was to determine the prevalence of Hepatitis A Virus (HAV) in sea food samples in the Isfahan and Shahrekord townships in Iran. From September 2010 to April 2011, a total of 300 samples of fresh fish, shrimp, crab and lobster were obtained from randomly selected retail stores in the Isfahan and Shahrekord townships in Iran. The samples were tested for the presence of HAV using a reverse transcriptase- polymerase chain reaction method. Out of the total number of samples examined, 8 (2.7%) were found to be positive for HAV. This virus was detected in 5% and 1.7% of fresh fish and shrimp, respectively. This study shows the importance of sea food as potential sources of HAV infection in people in Iran.

Cadmium and lead content in several brands of rice grains (Oryza sativa) in central Iran.

The aim of this study was to investigate the cadmium (Cd) and lead (Pb) content of several commercially available brands of rice grains (Oryza sativa) in central Iran. A total of 67 samples of the most widely consumed brands of rice grains were purchased from local bazaar markets in Shahrekord, Iran. The first step, grains of raw rice were digested by acid digestion method and then were analyzed by atomic absorption spectrometer. The results showed that Cd concentration in rice grains ranged from 0.0378 to 0.1225 ppm dry weight and its average concentration was 0.062 ± 0.019 ppm and Pb content ranged from 0.0405 to 0.1281 ppm dry weight and its average concentration was 0.068 ± 0.0185 ppm. Cd and Pb concentrations in the sampled rice grains were lower in comparison with their upper limits (0.2 and 0.2 ppm for Cd and Pb, respectively) approved by food sanitary standard. Therefore, it can be concluded that there is no health problems due to the consumption of brands of rice grains, for these two elements. The results indicated that weekly intake of Cd and Pb from rice grains was below the provisional tolerable weekly intakes recommended by WHO/FAO.

Identification & characterization of Shiga toxin-producing Escherichia coli isolates from patients with diarrhoea in Iran.

BACKGROUND & OBJECTIVES: Verotoxigenic Escherichia coli are important serotypes of enterohaemorrhagic E. coli (EHEC) subgroup that cause attaching and effacing lesions in enterocytes by producing verotoxins or shiga-like toxins resulting in haemorrhagic colitis (HC) and haemolytic uremic syndrome (HUS). The aim of this study was to detect these serotypes specially E. coli O157:H7 in stool samples of patients with diarrhoea and identification of virulence genes (STX1, STX2, Hly and EAE) in Shahrekord-Iran area using PCR technique. METHODS: Two hundred diarrhoeal stool samples of patients were collected through 2007-2008. Microbiological and biochemical examinations were done to detect the E. coli. Serological tests carried out to identify the O157 or O157:H7 serotypes. RESULTS: Of the 58 E. coli isolates, 16 (27.6%) were detected as STX1 carrying E. coli, four (6.9%) carrying STX2, eight (13.8%) carrying both STX1 and STX2, and 12 (20.7%) were Hly carrying E. coli, but none of the isolates contained EAE gene. None of the isolates were E. coli O157 or O157:H7 serotypes. INTERPRETATION & CONCLUSIONS: Our results revealed that verotoxigenic E. coli isolates other than O157 serotype were involved in causing diarrhoea in Shahrekord-Iran.

Prevalence and antimicrobial resistance of Campylobacter species isolated from chicken carcasses during processing in Iran.

The objective of this study was to determine the prevalence and antimicrobial resistance of Campylobacter spp. isolated from chicken carcasses during different stages of broiler processing in a major commercial poultry processing plant in southwestern Iran. Overall, 84 chicken carcasses were sampled from 4 sites along the processing line during a total of 7 visits. In addition, 14 water samples from the chiller tank were taken. Using the cultural method, 186 of 336 (55.4%) carcasses were positive for Campylobacter. Campylobacter jejuni was more frequently isolated (89.4%) than Campylobacter coli (10.6%). The frequency of Campylobacter spp. on carcasses was 54.8% after defeathering, 51.2% after evisceration, 69.0% 20 min after the chilling period started, and 46.4% 24 h after the chilling period completed. Campylobacter was positive in 85.7% of the samples taken from the chilling water. The frequency of Campylobacter spp.-positive carcasses was reduced in complete chilled chickens but not during the slaughtering process. Susceptibilities of Campylobacter isolates were determined for 10 antimicrobial drugs using the disk diffusion method. Of the 198 Campylobacter isolates tested, 92.9% were resistant to one or more antimicrobial agents. Resistance to tetracycline was the most common finding (78.3%), followed by resistance to ciprofloxacin (62.1%), nalidixic acid (58.6%), and enrofloxacin (44.4%).

Cadmium concentration in muscle, liver and kidney of sheep slaughtered in Falavarjan abattoir, Iran.

The aim of the present study was to investigate the levels of cadmium in sheep's muscle, liver and kidney from Isfahan and also to compare them with the levels reported in several other countries and with the maximum tolerance levels for the human consumption. The samples of muscle, liver and kidney of 60 animals around 1 to 6 years old were collected from the carcasses slaughtered in Flavarjan abattoir, Isfahan. Samples (acid digested and cadmium concentrations) were determined by graphite furnace atomic absorption spectrophotometry (GFAAS). The mean fresh weight concentrations in muscle, liver and kidney were about 0.0017 mg/kg, 0.0743 mg/kg and 0.02290 mg/kg, respectively. The mean concentration of cadmium in tissue samples was generally lower than the maximum acceptable concentration in European Commission (EC). Statistical analysis revealed a significant difference in cadmium concentration of liver and kidney between various age groups (p < 0.05).

Detection of Coxiella burnetii by nested PCR in bulk milk samples from dairy bovine, ovine, and caprine herds in Iran.

The epidemiology of Q-fever in Iran is essentially unknown. This study was conducted to determine the prevalence rate of Coxiella burnetii in bulk milk samples from dairy bovine, ovine, and caprine herds in Chaharmahal va Bakhtiari province, Iran. In this study, 376 bulk milk samples from 79 dairy bovine, ovine, and caprine herds were tested for C. burnetii using a nested PCR assay. The animals whose milk samples collected for this study were clinically healthy. In total, 13 of 210 (6.2%) bovine milk samples were positive; the positive samples originated from 5 of 28 (17.9%) commercial dairy herds. All 110 ovine bulk milk samples from 31 sheep breeding farms were negative and only 1 of 56 (1.8%) caprine bulk milk samples from 20 goat breeding farms was positive for C. burnetii. Although no extensive prevalence study was undertaken, the results of this study indicate that clinically healthy cattle are important sources of C. burnetii infection in Iran. To our knowledge, this study is the first report of direct identification of C. burnetii by PCR in bulk milk samples from dairy bovine and caprine herds in Iran. Further intensive prevalence studies on Coxiella infection among farmers, milk-processing workers, veterinarians, and slaughterhouse workers and on possible dangers of dairy products will be needed to elucidate the epidemiology of Q fever in Iran.

Occurrence of aflatoxin M1 in raw milk of five dairy species in Ahvaz, Iran.

During November 2007 to December 2008, 311 samples of raw milk from cow, water buffalo, camel, sheep, and goat were collected in the Ahvaz (southwest Iran). All of the samples were analyzed for presence of aflatoxin M1 (AFM1) by competitive ELISA technique. AFM1 was found in 42.1% of the samples by average concentration of 43.3+/-43.8 ng/kg. The incidence rates of AFM1 in raw cow, water buffalo, camel, sheep, and goat milks were, 78.7%, 38.7%, 12.5%, 37.3%, and 27.1%, respectively. The concentration of AFM1 in all of the samples were lower than Iranian national standard and FDA limit (500 ng/l), but in 36% of raw cow milk, 8% water buffalo milk, 3.9% sheep milk, and 5.7% raw goat milk samples were higher than maximum tolerance limit accepted by European union/Codex Alimentarius Commission (50 ng/l). The results showed that the milk of camel, goat, and sheep is safe respect to AFM1 contamination in this area.
