Comparison of educational effectiveness between lecture and demonstration based methods on emergency medical services providers of Mashhad city in dealing with patients suspected of having acute coronary syndrome

Introduction: acute coronary syndrome (ACS) is a common cause of emergency visit. Early administration of aspirin is associated with decreased mortality rate. Thus, aspirin should be administrated immediately to the patient with suspected ACS. Emergency medical services (EMS) providers should be trained to respond to heart emergencies and become familiar with presentations and complications of ACS. In this study, the effect of two educational methods â lecture and demonstration â on EMS providers were compared. ..

Peak bone mass, which can be defined as the amount of bone tissue present at the end of the skeletal maturation, and also it is an important determinant of osteoporotic fracture risk. The peak bone mass of a given part of the skeleton is directly dependent upon both its genetics and environmental factors. Therefore, the aim of the proposed research is a comprehensive systematic assessment of the pattern of peak bone mass in different countries across the globe. The present article explains the protocol for conducting such a research

Magnocellular based visual motion training improves reading in Persian

The visual magnocellular system is thought to play a crucial role in learning to read. Here therefore, we examined whether magnocellular based training could improve reading in children with visual reading problems. The participants were 24 male primary school students aged between 9-11 (Mean = 9.76, SD = 0.59) with specific reading difficulty. Experimental and control groups were matched for age, sex, educational level, IQ, reading abilities (measured by APRA), magnocellular performance as assessed by a random dot kinematogram (RDK) paradigm and recordings of their saccadic eye movements. The experimental group received twelve magnocellular based visual motion training sessions, twice a week over 6 weeks. During the same period, the control group played a video game with the help of a practitioner. All measures were made just prior to the training and were repeated at the 6th, 12th training session and one month later. The experimental group showed significant improvements in magnocellular function, visual errors and reading accuracy during the course of intervention. Follow-up assessment confirmed that these effects persisted one month later. Impaired magnocellular functioning appeared to be an important cause of poor reading in Persian. Hence magnocellular based training could help many children with specific reading difficulties. Also testing magnocellular function could be used as screening tool for detecting dyslexia before a child begins to fail at school

Unusual Airway Obstruction during General Anesthesia following Endotracheal Tube Cuff Herniation; A Case Report

Abstract Background: Airway management is always of great concern for anesthesiologists especially in the prone position. Utilizing an Armored endotracheal tube is considered to be safe in such patients. Cases Report: In this current case, we introduce a patient undergoing a wake-up test during spinal surgery who suffered from hypoventilation at the end of surgery. His condition improved only after extubation. After extubation, we confronted a herniated cuff that was not deflated, although we tried twice. We concluded that the patient's respiratory effort against obstructed airway produced a negative pressure, which made the cuff herniated, resulting in airway obstruction. Moreover, the patient biting the tube during the wake-up test damaged the tube and cuff deflation pathway. Conclusion: It is important to consider cuff herniation as a cause of obstruction when other possible etiologies are ruled out

Prevalence of congenital anomalies and related factors in live births in Zahedan, Southeast of Iran: A cross-sectional study

Background: The term congenital anomalies (CAs) refers to structural or functional abnormalities at the time of conception. Approximately 12 deaths related to congenital disabilities occur in every 10,000 babies born. Objective: This study aimed to evaluate the prevalence and associated factors of single and multiple CAs in live births in Zahedan, Southeast Iran. Materials and Methods: This cross-sectional study was conducted on 59,087 live births in a referral hospital in Zahedan located in the southeast of Iran from 2009 to 2019. All live births were examined by pediatricians and the CAs and categorized based on the international classification of diseases. Results: Of 59,085 live births, at least 883 had a significant anomaly, and the prevalence rate of CAs was about 149 per 10,000. Anomalies of the nervous (24.1%) and cardiovascular systems (21.10%) were the most frequent, occurring in 213 and 187 of the live births, respectively. Spina bifida is the most common anomaly of the central nervous system. The most common anomalies in the cardiovascular system were unspecified heart malformations (17.1%), cardiovascular malformations (18.7%), and patent ductus arteriosus (11.7%). Significant correlations were found between the parent’s consanguinity marriage, the mother’s age, an existing anomaly in the family, and relatives in single and multiple CAs (p = 0.02, p = 0.02, p < 0.001, p = 0.01, respectively). Conclusion: The prevalence of CAs was 149 per 10,000 live births. The highest prevalence of CAs was related to the central nervous system. Increasing the public’s knowledge about fetal defects can reduce the prevalence of CAs. Key words: Congenital anomalies, Hospitalization, Iran, Live birth, Prevalence, Risk factors

The effect of high-intensity interval training on IL-22 and STAT3 gene expression of liver tissue in steatosis animal model

Inflammation is a major component of almost all acute and chronic liver disorders, including non-alcoholic fatty liver disease. This study aimed to investigate the effect of high-intensity interval training on IL-22 and STAT3 gene expression of liver tissue in steatosis animal model. In this experimental study, 32 rats (weighing 200-250 gr) were selected and randomly divided into 4 groups including healthy control, fatty liver, HIIT and fatty liver + HIIT group. Rats were infected with fatty liver by oral tetracycline at a dose of 140 mg/kg (soluble in 2 ml of water) for 7 days. The HIIT exercise program performed on treadmill five sessions per week for 5 weeks. The IL-22 and STAT3 gene expressions in the liver tissue of samples were measured by Real Time PCR. Data were analyzed by One-way ANOVA and Tukey post hoc tests at significance level P <0.05. The results showed that the gene expression of IL-22 in liver tissue in HIIT group and fatty liver + HIIT was significantly lower than that in the fatty liver group (P = 0.001). Also, the gene expression of STAT3 in liver tissue in HIIT group and fatty liver + HIIT was significantly higher than that in the fatty liver group (P = 0.001). According to the results, the HIIT training program seems to help improve the liver steatosis

Human Herpesvirus-6 and Human Herpesvirus-7 Infection in Iranian Patients with Neurological Illness

Human herpes virus-6 (HHV-6) and HHV-7 have been implicated as causes of meningitis and encephalitis in children and adults. In this study the presence HHV-6 and HHV-7 DNA were tested in cerebrospinal fluid (CSF) sample taken from Iranian children, suffered from meningoencephalitis. From 2007 to 2009, 150 patients from Tehran with meningoencephalits who were referred to a pediatric ward in Rasoul Akram hospital, Tehran Iran, were enrolled in the present study. Conventional and BACTEC Ped Plus medium were used in conjunction with latex agglutination test and real time PCR for detection of HHV-6 and HHV-7 DNA in clinical specimen. All type of human herpes virus DNA was detected in 12 % (18/150) cases. HHV-6 DNA was detected in 4.7% and HHV-7 DNA was detected in 2 cases (1.4%). Human herpes virus-6 and HHV-7 DNA was detected in 6% of all studied cases. HHV-6 was slightly more frequent than HHV-7. Our findings were lower than the rate of other references but were higher than the findings of previous study in Iran. This variation might be due to differences in methods, age of study cases or epidemiologic and geographic variation

Comparison of the Effects of Media-based and Face-to-face Cardiac Rehabilitation Training Programs on Self-efficacy in Patients Undergoing Coronary Artery Bypass Grafting

Background: Several complications may occur in patients after coronary artery bypass grafting (CABG) leading to decreased self-efficacy. Rehabilitation training is the best method for reducing the complications and increasing self-efficacy. Various educational techniques lead to different rehabilitation results and levels of self-efficacy. Improving these measures requires the selection of the most appropriate educational technique. Aim: This study aimed to compare the effect of two media-based and face-to-face cardiac rehabilitation training methods on self-efficacy in patients undergoing CABG. Method: This clinical trial was conducted among 60 patients, who were randomly assigned into two groups, in Imam Reza Hospital, Mashhad, Iran, 2017. Cardiac rehabilitation training program was implemented face-to-face or using a researcher-made multimedia upon admission, discharge, at the start of cardiac rehabilitation, and at the end of the 10th session for half-hour. A researcher-constructed questionnaire on self-efficacy was completed by the participants in the mentioned stages. Data analysis was performed in SPSS software, version 16. Results: The mean ages of the participants in the face-to-face and multimedia groups were 56.0±8.1 and 57.5±7.3 years old, respectively. No significant difference was observed in the self-efficacy scores of the patients upon admission (P=0.36). However, there was a significant difference between the groups at the post-intervention stage (
