The relationship between attention-deficit/ hyperactivity disorder and trauma in adolescents

Objective: Attention-deficit/hyperactivity disorder (ADHD) is characterized by persistent and impairing levels of inattention, impulsivity and hyperactivity. Evidence shows that adolescents with ADHD are more exposed to trauma. This study aimed to investigate the relationship between ADHD symptom severity and trauma severity. Methods: In this descriptive correlational study, the study population included traumatic adolescents aged 12-18 years referred to Shohada hospital in Tabriz, Iran in 2016. Among this population, 91 subjects were selected. In order to exclude subjects with other psychiatric disorders, a psychiatrist performed clinical interviews with them. In this regard, the short form of Conner’s Comprehensive Behavior Rating Scales Revised Edition (CBRS-R) and Pediatric Trauma Scale were used. For data analysis, Pearson correlation coefficient and independent t test were applied. Data were analyzed using SPSS software version 22. Results: There was a significant positive relationship between trauma severity and ADHD score, hyperactivity, and oppositional/Impulsivity (P < 0.01). Conversely, no statistical significance was observed between attention deficiency and trauma severity. The severity of trauma was higher among ADHD group than normal individuals. There were also correlations between socioeconomic status (SES) and oppositional/impulsive patients. In this regard, higher scores of oppositional/impulsivity were observed among patients with lower SES. Conclusion: Traumas have significant effects on economic and humanistic aspects of life in modern era. Our findings showed that there was a statistically significant relationship between hyperactivity-inattention and trauma intensity in adolescents. Therefore, to prevent traumatic events, ADHD screening at schools is suggested. By the same token, informing parents through mass media can help reduce the consequences of inattention/ hyperactivity disorder in the society

Gd 3+

Designing a unique theranostic biocompatible, biodegradable, and cost-effective agent which is easy to be synthesized as a biohybrid material was the aim of this study. In this matter, asparagine attached to anionic linear globular dendrimer G2 (as a biocompatible, biodegradable, and cost-effective agent which is negatively charged nanosized and water soluble polymer that outweighs other traditionally used dendrimers) and finally contrast agent (Gd3+) was loaded (which made complexes) in synthesized asparagine-dendrimer. Observations revealed that, in addition to successful colon cancer and brain targeting, Gd3+-dendrimer-asparagine, the proposed theranostic agent, could increase T1 MR relaxation times, decrease T2 MR relaxation times significantly, and improve contrast of image as well as illustrating good cellular uptake based on florescent microscopy/flow cytometry and ICP-mass data. In addition to that, it increased tumor growth inhibition percentage (TGI%) significantly compared to FDA approved contrast agent, Magnevist. Totally, Gd3+-anionic linear globular dendrimer G2-asparagine could be introduced to the cancer imaging/therapy (theranostics) protocols after in vivo MR and fluorescent analysis and passing clinical trials. Hence, this nanotheranostic agent would be a promising candidate for brain drug delivery and imaging in the future

Assessment of Interior and Area Artificial Lighting in Hospitals of Hamadan City

Background & Objectives: Comfort lighting is one of the most important topics, which provides optimum physical conditions in general environment and workplaces such as hospitals. This study aimed to evaluate general, local and area artificial illumination of Hamadan city hospitals . Methods : In this descriptive-analytical study, general, local and area artificial illumination in seven Hamadan hospitals in 2006 were evaluated. Lighting intensities (illuminance) were measured according to recommended IESNA method using the lux meter model (Lutron-Lx102) in the early hours of night. Lighting quality parameters such as color rendering, technical suitability of design and lighting uniformity were evaluated. Data was analyzed using SPSS 13 . Results : The average of interior illuminance was 90.44 ± 46.97 lx, which was lower than the national recommended limits. Maximum and minimum intensity values of interior illuminance were in nursing station and laboratory, respectively. The average of area illuminance was 47.92 ± 53.2 lx and local illuminance was 131.5 ± 60.2 lx, which were lower than the recommended limits. Maximum intensity of local illuminance was in laboratories and the minimum levels were in admitted rooms, checkup and injection units. In total, 90.6% of general interior lighting systems, 83.3% of area lighting systems and 100% of local lighting systems had unaccepted design . Conclusion : The average of general, local and area illuminance in Hamadan hospitals were not within the acceptable limits for comfort lighting. To obtain comfort lighting in studied hospitals, reforming and modifying lightening systems is necessary

Self-reported risk behaviors among offender motorcyclists in Ahvaz City

Introduction: Road traffic accidents are among the most critical public health issues. Many people die on the roads each day and tens of millions sustain nonfatal injuries. The aim of this study is to describe the high-risk behaviors of motorcyclists in which police had to confiscate their motorcycles. Methods: This cross-sectional study was carried out on 240 motorcyclists in Iran from December 2010 to February 2011. A researcher-created questionnaire was used to collect data on self-reported high-risk behaviors, including passing the crossroads without considering the traffic light, refusing to wear a helmet, performing stunts in the street, and driving in the opposite direction. The collected data was descriptively analyzed. Results: The mean age of motorcyclists was 29.3 years (SD=8.26). Twenty-six percent (n=62) of the participants did not have a motorcycle driver’s license. The analysis of risk behaviors showed that 60.8% (n=146) of the motorcycle drivers usually passed crossroads without considering the traffic light and 20.8% (n=50) performed stunts in the street. Conclusions: This study indicates that the prevalence of high-risk behaviors among motorcyclists is significant. Health education interventions may inhibit these behaviors, thus reducing the risk of injuries
