The aim of this study was to standard and assign validity and reliability of the Trauma Symptom Checklist for Children - TSCC-A. Normative data for the TSCC-A were based on 3.042 students participating in a prevalence child abuse study in 19 different locations of Tehran and 140 participants who had been referred to the run away children centers in Tehran. After the TSCC was validated on run away and abused children, it was made available to researchers doing larger studies on normative group. Reliability analysis of the TSCC-A scales in the normative sample demonstrated high internal consistency. The evidence for its validations (convergent, discriminate and construct validity) showed that they were significantly acceptable. This paper presents data demonstrating the psychometric reliability and validity of the TSCC-A scales in Iranian student population. We suggest to include the TSCC-A in a battery of relevant standardized tests. [ABSTRACT FROM AUTHOR]

Background: Sleep disorders can be harmful to our health and treating them can also be expensive. Due to the widespread occurrence and impact of sleep disorders, it is valuable to investigate and study them from an epidemiological perspective. Therefore, this study aimed to determine the prevalence of sleep disorders among Iranian adults in 2022., Method: This is a cross-sectional study that examines the prevalence of sleep disorders and problems in Iranian society. The participants were selected using a mixed sampling approach (utilizing virtual space and cluster sampling). A two-part package was used for evaluating participants sleep problems, which included a demographic profile form and the Holland Sleep Disorders Questionnaire. After collecting the data, appropriate statistical tests in SPSS version 25 were utilized for analysis., Results: A total of 6013 questionnaires were fully filled out for this research, with participants answering the specific questions. The participants' score on sleep disorders was 1.94, which means 44.1% of them suffer from sleep disorders. The results indicated that the prevalence of sleep disorders in this study was as follows: insomnia (35%), parasomnia (35.3%), circadian rhythm sleep disorder (38.4%), hypersomnia and excessive daytime sleepiness (39%), restless leg syndrome and leg movements during sleep (43%), and breathing disorders related to sleep (38.4%). The prevalence of sleep disorders among the study participants demonstrated a significant relationship with most of their demographic variables (P < 0.001). The Pearson correlation coefficient also revealed an inverse and significant relationship between the prevalence of sleep disorders in the study participants and their age, monthly household income, and BMI (P < 0.001)., Conclusion: Overall, the results depicted a relatively high prevalence of sleep disorders in the studied community. These findings emphasize the need for interventions to prevent and treat sleep disorders in society., Competing Interests: Declarations Ethics approval and consent to participate The studies involving human participants were reviewed and approved by Ethical Committee of the Kermanshah University of Medical Sciences (IR.KUMS.1400.404).

Objective: The present study was investigate parents' experiences of children with Epidermolysis bullosa. So, this descriptive phenomenological qualitative study was conducted on 17 parents of children with EB from five hospitals affiliated with the University of Medical Sciences, west of Iran. Data was collected through semi-structured interviews. COLAIZZI's method was also used to analyze the data., Results: Three main themes were extracted in this study: invasion of psychological crisis, alive but no living, and comprehensive support, including 10 categories. The parents of these children are the target of psychological crises that severely reduce their quality of life. In this regard, they need extensive support to improve their living conditions. Therefore, it is suggested to provide cultural and institutional contexts in which all components of the children's dignity are emphasized., (© 2024. The Author(s).)

Objectives: Antimicrobial resistance and biofilm formation are increasingly significant public health concerns. This study aimed to examine the antibacterial and antibiofilm properties of carbon dots (C-dots) alone and in combination with antibiotics against biofilm-forming isolates of Pseudomonas aeruginosa., Methods: The antibacterial property of C-dots was investigated by broth microdilution method against ATCC PAO1 and P. aeruginosa clinical isolates. The antibacterial effect of the C-dots and ciprofloxacin combination was investigated using the checkerboard method. The antibiofilm effect of the C-dots alone and its combination with ciprofloxacin was evaluated using the microtiter plate method. Subsequently, the toxicity of each agent was tested on L929 fibroblast cells. In the end, the effects of C-dots on the expression levels of pslA, pelA, and ppyR genes were determined using real-time quantitative PCR., Results: The combination of C-dots and ciprofloxacin exhibited a synergistic effect. Additionally, this compound substantially decreased bacterial growth (P < 0.0001) and inhibited biofilm formation at MIC (96 µg/mL) and sub-MIC (48 µg/mL) concentrations (P < 0.0053, P < 0.01). After being exposed to C-dots at a concentration of 1mg/mL for 24 hours, the survival rate of L929 cells was 87.3%. The expression of genes pslA, pelA, and ppyR, associated with biofilm formation in P. aeruginosa, was significantly reduced upon exposure to C-dots (P < 0.0023)., Conclusions: The findings demonstrate a promising new treatment method for infections. Furthermore, reducing the dosage of antibiotics can lead to an improvement in the toxic effects caused by dose-dependent antibiotics and antimicrobial activity., (Copyright © 2023 The Author(s).

This study aimed to assess the awareness and performance of Qom citizens towards using disinfectants and compared its relationship with geographical distribution of COVID-19 outbreak in Qom, Iran. The study was conducted by a researcher-made questionnaire during April and May, 2020. COVID-19 incidence data for each district of city was obtained from health department of Qom province. Data were analyzed using Excel, SPSS and ArcView (GIS) softwares. It was found that the highest level of citizens' awareness (52%) was in the weak range while their performance (56%) was in the good range. According to Spearman's correlation analysis, there was a strong correlation (rho 0.95) between the total mean of awareness and performance ( p < 0.01). The highest incidence rate of COVID-19 was in district 7 which had the lowest mean score in both awareness and performance. In addition, the results of ANOVA (LSD-least significant difference) showed that there was a significant difference ( p < 0.05) between district 7-with lower mean scores in awareness and performance-and other districts. Overall, it is concluded that citizens' awareness level was lower than that of their performance. This conclusion not only calls for more training programs to be implemented in public places, schools, universities and governmental offices, but it also necessitates maintaining a proper and timely training about using disinfectants.

Clostridium difficile is the most common cause of nosocomial diarrhea. It is usually a consequence of antibiotic treatment, But sporadic cases can occur. This study was aimed to determine the frequency of the nosocomial Clostridium difficile (C. difficile) associated diarrhea in Tehran University of Medical Sciences hospitals and study of antibacterial susceptibility of isolates. In this study a total of 942 stool samples from patients with nosocomial diarrhea that were hospitalized in Imam Khomeini hospital, Shariati hospital and Children clinical center were collected. The samples were cultured on a selective cycloserine cefoxitin fructose agar (CCFA) and incubated in anaerobic conditions, at 37°C for 5 days. Isolates were characterized to species level by conventional biochemical tests. Bacterial cytotoxicity was assayed on tissue culture (vero). Antimicrobial sensitivity of isolated toxigenic C. difficile were investigated by kirby Beuer method (disk diffusion). Our findings show that, of the total patients, 57 toxigenic C. difficile (6.1%) were isolated. Results of statistical analysis show significant differences between the rate of isolated toxigenic C. difficile and age group of patients (P<0.05). Among the wards of selected hospitals, in gastroenterology of Children clinical center, Toxigenic C. difficile was isolated from patients most frequently. The sensitivity of isolates to vancomycin, Chloramphenicol and ceftriaxone were higher than other antibiotics. Toxigenic C. difficile is a common hospital-acquired infection. The organism was found in 6.1% hospitalized patients. Further studies to evaluate the rate and role of toxigenic C. difficile in nosocomial diarrheal processes, ecological and pathogenic terms are suggested.

Harm reduction, including needle exchange and opioid substitution therapy, has been demonstrated to reduce high-risk behavior and HIV infection among injection drug users. An increasing number of countries in the Middle East, North Africa, and Asia, including those with Muslim majorities, have experienced or are at risk for HIV epidemics initiated by burgeoning injection drug use. Although use of intoxicants is expressly forbidden within Islam, the local culture impacts the interpretation of Islamic law and influences the response to drug misuse, whether punitive or therapeutic. Harm reduction programming has received varying acceptance within this global region, which may be reflected by national trends in HIV prevalence. The purpose of this paper is to examine cultural and religious response to injecting drug use and associated HIV prevalence trends in Malaysia and Iran, with possible application of lessons learned to an emerging situation in Afghanistan.
