Background: The object of this study was to determine the epidemiological characteristics of deliberate self-poisoning in adolescents referred to the only poisoning center in Tehran. Methods: In a cross-sectional study, all cases of acute poisoning at the Loghman Hakim Hospital from May to December 2003 were reviewed. Data for adolescents (13-19 years of age) were analyzed by SPSS for Windows, version 13 and STATA, version 8. Results: From a total of 9203 cases of deliberate self-poisoning, 28.5% were adolescents (2626 cases). The male/female ratio was 1/2.2. Approximately 87% were unmarried and 56% were students, while a total of 4859 different drugs/agents were used for self-poisoning (an average of 1.85 for each case). The majority of patients was from urban areas and had no history of attempted suicide. There was no difference between males and females regarding history of psychiatric and somatic disorders, though there was a significant difference in the average of age between male and female adolescents. Conclusions: Among adolescents, self-poisoning is more common in girls while the mean of age is younger in boys. Although the prevalence of psychiatric disorders in adolescents appears to be less than the general population, this may be related to differences in their situations or due to underestimation of their frequencies. Psychiatric care should be a necessary component of the care administered to adolescents who attempt suicide and must be based on the needs and basic assessment of the patient’s status. Research regarding the familial history of abuse, neglect, self-harm/ poi- soning should be undertaken so that such social issues can be prioritized and addressed.

Background: The aim of this study is to describe the mental health and social profile of adolescent thalassemic patients through self-report and GHQ-12 test. Materials and Methods: With convenience sampling, 156 consecutive adolescent thalassemic patients, recruited during a 20month period, filled in a semi-structured self-administered questionnaire in addition to a GHQ-12 questionnaire. Results: 100 cases (64.1%) denied having health problems. 71 patients (45.5%) described their health status as not bad and 39 cases (25%) as good. The average GHQ-score was 6.12 (0.95 CI- 5.69-6.56). Nine cases (5.8%) scored low (0-1) and 21 cases (13.5%) scored borderline (2-3), while the score of 124 patients (79.5%) was favorable (4-12). There was a significant difference between mean scores in different age groups (p= 0.036) and 78 percent of those with low scores were in their late adolescent period (18-21 yrs). 15 patients (9.6%) had quit school due to their health problems. Mean GHQ score for quitters was significantly lower than those going on with their studies (p= 0.017). Conclusion: These adolescent thalassemic patients seemed to have coped properly with their disease. Possibility of denial should also be considered. Further studies for detection of high-risk groups for psychosocial derangements can help us in applying appropriate and timely preventive and supportive measures.

Objectives: To improve the performance of the trauma management system, we examined the pattern of injury “Hot spots” in Tehran. Methods: All hospitals in Tehran admitting trauma victims were included in this study. In randomly selected days throughout the year (41 days), trained interviewers collected data on trauma cases round the clock. If the patient was hospitalized, further information about the cause of trauma and its mechanism was recorded. Results: In all, 4198 patients were admitted to the hospitals and interviewed. The mean age of the patients was 29.8±18 years. 78 percent of our patients were male. The major mechanism of injury was traffic accident followed by falls, penetrating injuries, and alcohol intoxication. The highest number of cases came from the 4th, 20th and 12th municipal districts (Bazaar, Pa-Menar, Khaniabad). If we considered only road traffic accidents (As the major cause of trauma), the 4th, 20th, and 12th regions were the most frequent sites of occurrence. Conclusion: More comprehensive studies have to be performed on the causes of injuries in the “Hot spots” to elucidate what preventive strategies would effectively reduce the incidence of trauma in these areas.

Objective(s): To identify factors influencing the severity of injuries in motor vehicle crashes. Methods: The source of data was the national trauma study-Tehran (1999-2000), performed in 6 major hospitals in Tehran. We looked at demographic and pre-hospital data on 564 car passengers injured in non-fatal traffic accidents. We used the injury severity score (ISS) to determine the severity of injuries. Results: Most cases of trauma involved the extremities and the bony pelvis. Injuries were more severe in passengers of pick-up trucks compared to those injured in crashes involving 2 passenger cars. Also, those traveling in pick-up trucks were more likely to be injured in the head and check (P

Objective(s): The objective of this study was to determine coping with stress abilities of clinical residents at Tehran University of Medical Sciences and to explore whether these abilities differ between Junior and Senior residents or between males and females. Material & Methods: In this cross-sectional study, The Coping Skills Inventory was used for determination of different aspects of coping in a randomly selected sample of clinical residents in 14 different specialties at Tehran University of Medical Sciences. Results: In all 277 residents were studied. Of these 62.7 percent were at the first or second years of residency, while the other 3 7 .5 percent were at the third or fourth years. The male to female ratio was 1.1. The mean coping score was 64.83. Excellent and very good abilities were observed in 79.8%. The mean self-estimated coping scores was 63.13 that was significantly correlated with the calculated scores (Pearson correlation =0.47, P < 0.001). The mean coping score for Juniors was not significantly different from that of Seniors; but, Juniors were less flexible, resourceful and self-reliant than their Senior counterparts (P = 0.016, P=0.005 and P=0.006, respectively). A significant difference was observed between the mean coping score of females and males (P< 0.001). The most important stressors were sensitive responsibilities, low salaries and sleep deprivation. Long hours of work, nightshifts and multiple roles were more frequently reported by the Juniors than Seniors as major stressors (P= 0.001). Conclusion: Although a high percentage of residents had very good coping scores. However the difference in coping between genders emphasizes on the importance of support and education for female residents to cope more effectively with their job stress.

Objective(s): To determine the frequency of depression among pregnant women visited at the prenatal clinic, Imam Khomeini Hospital, Tehran, Iran. Material & Methods: This was a cross-sectional study in which by convenience sampling, pregnant women visited at the prenatal clinic during a 2-month period were studied. The instrument for data collection was Beck Depression Inventory, which is a self-administered valid and reliable questionnaire, measuring manifestations of depression. Scores higher than 9 were interpreted as depression. Results: Of 170 pregnant women, 16.5 percent had experienced depression symptoms before pregnancy, 9.4 percent reported depressive episodes in their relatives, 4.7 percent had suffered from depression during/after previous pregnancies and 8.2 percent had the history of premenstrual depression. 48.2 percent had experienced at least one stressor during the current pregnancy. The mean score on Beck Inventory scale was 11.47 (95%CI= 10.09-12.58). At the time of the study, at least 30.6 percent suffered from depression. Nevertheless, none were under supervision of a heath care professional for management of depression. Conclusion: The findings suggest that the implementation of strategies to integrate mental health screening in prenatal cares is needed.

Objective: The high burden of injuries in Iran necessitates the establishment of a comprehensive trauma care system. The purpose of this paper is to describe the current status of trauma system regarding the components and function.Methods: The current status of trauma system in all components of a trauma system was described through expert panels and semi-structured interviews with trauma specialists and policy makers.Results: Currently, various organizations are involved in prevention, management and rehabilitation of injuries, but an integrative system approach to trauma is rather deficient. There has been ongoing progress in areas of public education through media, traffic regulation reinforcement, hospital care and prehospital services. Meanwhile, there are gaps regarding financing, legislations and education of high risk groups. The issues on education and training standards of the front line medical team and continuing education and evaluation are yet to be addressed. Trauma registry has been piloted in some provinces, but as it needs the well-developed infrastructure (regarding staff, maintenance, financial resources), it is not yet established in our system of trauma care.Conclusions: It seems that one of the problems with trauma care in Iran is lack of coordination among trauma system organizations. Although the clinical management of trauma patients has improved in our country in the recent decade, decreasing the burden of injuries necessitates an organized approach to prevention and management of trauma in the context of a trauma system.

Objective: Seat belt use during pregnancy reduces injury to the mother and her fetus. During recent years, the use of seat belts has been mandated by law in Iran. The purpose of this study was to determine the attitudes and practices of pregnant women regarding seat belt use.Methods: In this cross-sectional study, we asked 335 pregnant women at a hospital-based prenatal care clinic on the use of safety belt before and during pregnancy. SPSS version 13.0 was used for data analysis.Results: The mean age of study subjects was 27.3 years ± 5.3 years with the median of 27 years. Compared with the seat belt use before pregnancy, no change was detected in 48.7% of the women; seat belt use had increased in 17.5 % of them and decreased in 33.8 %. Eighty-one percent of women knew the correct placing of both lap belt and shoulder belt. Only 4% of women had received education on proper restraint use during pregnancy.Conclusions: The prevalence of seat belt use during pregnancy is lower than reports which are mostly from developed nations. The fact that about one-third of women have decreased their seat belt usage during pregnancy highlights the importance of education of mothers on this topic. [ABSTRACT FROM AUTHOR]

OBJECTIVES: To investigate the relationship between perceived risk and risk-taking behaviors during the Iranian Last Wednesday Eve Fireworks (ILWEF). METHODS: A random sample of 2475 Tehranian households were asked on perceived risk of injury, risk-taking behaviors, experience of injuries, and their perception of ability to manage the harmful events during the ILWEF. RESULTS: Lower perceived injury risk and higher perceived ability of managing an injured household member were associated with participation in fireworks practice and incidence of injury. CONCLUSION: These findings can be of practical importance to increase safety during festivals by improving risk perception in the community. [ABSTRACT FROM AUTHOR]

Objective: Although long bone fracture in children is not life-threatening, it may cause major disability, loss of working days and severe psychological distress. We conducted this study to determine the pattern of extremity fracture due to trauma in children.Methods: During one year in six general hospitals in Tehran, trauma patients who were hospitalized for more than 24 hours and sustained injuries within seven days before admission were included in the study. The records of children (< or = 16 years old) hospitalized in six general hospitals in Tehran due to trauma were reviewed prospectively.Results: During the study period, 1 274 children had sustained extremity fractures. Male to female ratio was 3.6/1, with the mean age of (10.3+/-4.2) years. Falls and traffic crashes were the main causes of injuries, with the percentages of 57.3% and 37.1%, respectively. Simple fall (falling on the ground) consisted 60% of patients that sustained fall-related injuries. Pedestrians and bicycle riders comprised most of the cases that were injured due to traffic crashes. Of our cases, 56.8% sustained fractures in the upper extremities and 43.2% in the lower extremities. Forearm was the most common fracture site (34.1%). Comparing our results in preschool and school-age children, falls were the main cause of injuries in both groups, but fractures of lower extremities were significantly more common in preschool children.Conclusions: Improvement of physical condition of sidewalks and crossings in roads will be necessary for prevention of injuries. More attention to safety of home environment should be paid for control of preschools'injury at home. Education of children and adults is necessary to reduce injuries resulting from road traffic crashes. [ABSTRACT FROM AUTHOR]

Abstract Background Spring cleaning is a popular tradition in Iran as well as in many other countries. The purpose of our study was to determine the pattern and compare the incidence of spring cleaning related injuries in Tehran, in the years 2007 and 2008. Methods In the year 2007, a household survey was performed in Tehran by random cluster sampling. The survey was repeated in May 2008 with the same clusters and starting points, but different households. The incidence of spring cleaning related injuries, the age and sex of injured person(s), the mechanism, type and cost of injuries were recorded through semi-structured interviews. The incidence rates of injuries and injuries leading to health visits (severe) according to sex and age groups were calculated. Data were analyzed using SPSS and STATA statistical softwares. Results The incidence of all and severe spring cleaning related injuries were 3.8 (3.0 - 4.8) and 1.6 (1.1-2.3) per 1000, respectively. The most common mechanisms of injuries were falls, followed by cutting and lifting heavy objects or overexertion. Falls were also the main mechanism of severe injuries. The most common injuries were open wounds, followed by superficial injuries (including contusions) and sprain and strain. Among severe injuries, the most frequent injuries were open wounds and contusions, followed by dislocations. The injuries were most common among women with an incidence of about 8.4 per 1000 in women older than 18 years of age (severe injuries: 3.4 per 1000 (2.2-5.1)). Conclusion The incidence of spring cleaning related injuries is high enough to raise concern in health system authorities. It could be estimated that about 23,927 to 38,283 persons get injured during the spring cleaning in Tehran at the beginning of every Persian new year. In addition, about 8,773-18,344 of these cases are expected to be severe enough to lead to medical attention (considering 7,975,679 as the population of Tehran at the time of study). Improving awareness of families, especially young women, regarding the scope and importance of spring cleaning safety can be suggested as the first population-based strategy to decrease the incidence of these injuries.

Abstract Background Iran has one of the highest rates of road traffic crash death rates throughout the world and road traffic injuries are the leading cause of years of life lost in the country. Using child car safety seats is not mandatory by law in Iran. The purpose of this research was to determine the parental willingness to pay (WTP) for child restraints in Mashad, the second most populated city in Iran with one of the highest rates of road traffic-related deaths. Methods We surveyed 590 car-owner parents of kindergarten children who were willing to participate in the study in the year 2009. We asked them about the maximum amount of money they were willing to pay for car safety seats using contingent valuation method. Results The mean age of children was 33.5 months. The median parental WTP for CSS was about $15. Considering the real price of CSSs in Iran, only 12 percent of responders could be categorized as being willing to pay for it. Family income level was the main predictor of being willing to pay. Conclusions The median parental WTP was much lower than the actual price of the safety seats, and those who were of lower socio-economic class were less willing to pay. Interventions to increase low-income families' access to child safety seats such as providing free of charge or subsidized seats, renting or health insurance coverage should be considered.

Abstract Background The purpose of this research was to examine whether waterpipe smokers experience increased risk of motor vehicle crashes. Methods In a telephone survey, a random sample of Iranian drivers were asked to report their age, gender, vehicle age, whether their vehicles were equipped with anti-lock braking system (ABS), average daily drive time (DDT), whether they smoked cigarette or waterpipe, whether they had diabetes mellitus (DM), number of traffic crashes during the last calendar year and whether the crash involved a pedestrian or another vehicle. Results A total of 2070 motor vehicle owners with the mean age of 41.6 ± 11.45 were interviewed. The annual incidence of Road Traffic Crashes (RTC) was 14.9%; 14.0% involved a collision/s with other vehicles and 0.9% with pedestrians. There was an association between the RTC and male gender, DDT, being a cigarette smoker, being a waterpipe smoker and DM in univariable analysis. The association between RTC and being a waterpipe smoker and also cigarette smoker was significant in multivariable analysis after adjustment for DDT. Conclusions Being waterpipe and/or cigarette smoker and DDT were the independent predictors of the number of traffic crashes in Poisson regression model. If the increased risk of RTC among waterpipe or cigarette smokers is seen in other studies, it would be beneficial to promote tobacco cessation and control strategies through injury prevention initiatives.

Abstract- Studies of the epidemiology of civilian vascular trauma in developing countries are rather few. This is a prospective study of our experience with vascular trauma in a referral university hospital in Tehran, Iran. The aim was to study the etiology, pattern of injuries and the mortality and morbidity rates due to vascular trauma in our population. In this cross-sectional study, all trauma patients suspicious of having vascular injuries who were admitted to Sina Hospital between March 2002 and May 2003 were included. Among 123 studied cases, there were 109 males and 14 females.Blunt injuries were more common than penetrating ones (56.1% vs. 43.9%). The most common anatomical site of vascular injuries had been knee and lower leg. In fact, cases with lower extremities vascular trauma were twice as common as those with vascular trauma in upper limbs (59.1% vs. 27.3%). The commonest injured vessels were popliteal artery followed by femoral artery. Arterial repair with graft interposition was done in 23 cases and bypass graft in 13 cases. Procedures on veins were performed in 24 cases. Five patients (4.06%) died and in 3 cases the patients died because of non-vascular reasons. The present study allows an understanding of the epidemiology of vascular trauma in the one of the major trauma centers in the metropolitan city of Tehran. The majority of our cases were young males sustaining vascular injuries due to road traffic accidents or being stabbed with knives. It also has important implications for vascular injury prevention in our community.

BACKGROUND: Injuries are a major health problem in developing countries. Recently, the occurrence of injuries and those related to mortality have increased dramatically in Iran. We have conducted this study to report domestic research publications in the field of trauma from 2000 to 2006 in Iran. METHODS: The contents of 128 biomedical journals were analyzed. Sina Trauma Data Bank (STDB) was selected as an indicator of trauma related articles that have been published in Iranian biomedical journals. RESULTS: The number of trauma related articles in Iran increased during the seven year period (2000 - 2006), but the percentage of total publications was not significantly different. The mean number of authors per article was 2.7+1.3 (1 to 12) and all first authors were Iranian. Females constituted 15.4% (n=156) of first authors. Original articles were the most frequently published articles (n=871; 86.2%). Treatment of injuries and ensuing complications were the most common topics (42%) followed by war injuries (14.1%). Traffic accidents, as the leading cause of trauma death in Iran, were investigated in 27 (2.7%) articles. CONCLUSION: According to our results, it seems that more attention from researchers and health-policy makers towards trauma is necessary in our country. In addition, publishing a journal with the main theme of injury and trauma could be an effective means for increasing the proportion of trauma related articles. [ABSTRACT FROM AUTHOR]

The significant burden of home injuries has become a growing concern that affect thousands of people every year across Canada. This study examined the relationship between neighbourhood deprivation and unintentional injuries occurring at home leading to hospitalizations in British Columbia (BC) between 2015 and 2019. This study used de-identified hospitalization data on unintentional home-related injuries from the Discharge Abstract Database (DAD) and population data for each dissemination area from Statistics Canada's 2016 Census Profiles. Hospitalization rates were computed for unintentional home-related injuries across four dimensions specified in the Canadian Index of Multiple Deprivation (CIMD) for BC. For three CIMD dimensions (situational vulnerability, economic dependency, and residential instability), unintentional home injury rates were higher in areas with higher deprivation, while the inverse was observed for ethno-cultural diversity. Understanding socio-economic disparities within neighbourhoods enables injury prevention partners to identify vulnerable populations and prioritize the development and implementation of evidence-based injury prevention interventions.

This paper examines how experiences with a previous pandemic, particularly HIV/AIDS, may have informed approaches to COVID-19, with a focus on sexual orientation., Method: The sample was drawn from an online survey of Canadians 55+ conducted in 2020, comprising 1143 persons (mean age = 67; 88 gay or bisexual (GB) men, 65 lesbian or bisexual (LB) women, 818 heterosexual women, and 172 heterosexual men). Respondents reported if they, or someone close to them, "had been affected by" one or more pandemics and whether COVID-19 led them to "think more about their prior epidemic/pandemic experiences" and/or feel they "couldn't handle it again". Correlated items reflecting feeling "they have been here before"; "prepared for what is happening"; and "like they needed to act or do something" formed a scale named "agentic familiarity"., Results: About half of respondents reported thinking about their previous pandemic experience; about 5% reporting feeling like "they couldn't handle it again" with no gender or sexual orientation differences. Higher agentic familiarity scores were found for GB men and for those with experience with HIV/AIDS vs. other pandemics., Discussion: These outcomes speak to resilience and growth experienced by LGBT (and especially GB) persons through shared stigma and trauma-with implications for current pandemic experiences and future actions, like advance care planning.

Objectives: Although Gross hematuria in patients receiving anticoagulants is not very common, it is one of the most common reasons of consulting with urologists. It is recommended to investigate urinary tract malignancies but simultaneous approach to anticoagulation and hematuria so as the optimum balance could be attained, is not clearly defined in the literature yet. We aim to answer pitfalls of hematuria management in anticoagulant receiving patients in this manuscript., Materials and Methods: In a prospective case control study during 2017-2019, we observed and collected the data of patients receiving anticoagulant therapy and suffered from gross hematuria with coagulation parameters in prophylactic or therapeutic range in an academic hospital affiliated to Tehran University of Medical Sciences. SPSS 24th version was used for descriptive analysis of collected data., Results: Sixty-six patients encountered hematuria while receiving anticoagulant therapy. Although hematuria was more common in male patients, its recurrence was higher in female patients. It started mostly in first 72 h of therapy and was anticoagulant-dose dependent. Degree of hematuria was mostly mild or moderate by visual estimation and controlled easily by holding the anticoagulant therapy for less than 2 days. Anti-platelet therapy, urinary catheterization and patient's activity did not have any effect on re-bleeding rate., Conclusion: Considering the fact that ruling out the urinary tract malignancy is mandatory in these patients, moderate and severe hematuria can be controlled simply by short term holding the anticoagulant therapy while continuing antiplatelet therapy albeit there is possibility to continue them in mild cases. Removing urinary catheters and decreasing the patient's mobility are not recommended. In order to decrease the recurrence of hematuria, re-establishing anticoagulation with LMWH and non-Vitamin D dependent oral agents rather than continuing Heparin and Warfarin might be helpful.

Background: Behavioral and psychological symptoms of dementia (BPSD) exhibited by persons with dementia (PwD) in nursing home communal areas are generally managed by segregation and/or pharmacological interventions., Objective: This study trialed MindfulGarden (MG), a novel digital calming device, in a Canadian nursing home., Methods: Participants were 15 PwD (mean age = 87.67; 5m,10f; mean MMSE = 11.64±7.85). Each was observed by a research assistant (RA) for an average of 8-10 hours on two separate days. The RA followed them during time spent in communal areas of the nursing home including their unit's dining space, lounges, and corridors and spaces shared with other units (e.g., gym and gift shop) and documented any BPSD exhibited. Day-1 provided baseline data; on Day-2, residents were exposed to MG if nursing staff considered their BPSD were sufficiently intense or sustained to warrant intervention. Staff rated the impact as positive, neutral, or negative., Results: On Day-1, 9 participants exhibited both aggressive and non-aggressive behaviors, 4 non-aggressive behaviors only, and 2 no BPSD. On Day-2, 7 exhibiting aggressive behaviors were exposed to MG. Staff reported MG as having distracting/calming effects and gave positive impact ratings to 6/13 exposures; there were no negative ratings. The most common aggressive BPSD on days of observation were pushing/shoving and screaming., Conclusion: MG may have value as a "psychiatric crash cart" in de-escalating agitation and aggression in care home settings., Competing Interests: Prior to the study, the first author (G.G) acted as an advisor for MindfulGarden but derived no financial or other tangible benefits from MindfulGarden Digital Health, Inc. or Switch United, the MindfulGarden developers., (© 2021 – The authors.

Objectives: To describe our technique of percutaneous nephrolithotomy (PNL) in patients with mesh-repaired flank incisional hernia. Polypropylene mesh which is used for fascia strengthening in hernia repair elicits intense inflammatory reaction and the consequent fibrosis alters the characteristics of abdominal wall. Thus, prior history of flank hernia repair with mesh may result in percutaneous nephrolithotomy failure., Materials and Methods: Demographic data, renal stones characteristics, and any complication during surgery and follow-up of patients who were treated by PNL during 2011 to 2020 and had mesh in their flank region were collected., Results: Percutaneous nephrolithotomy was performed without any problem in 8 patients with guide of ultrasonography., Conclusion: Based on our experience, ultrasound-guided PNL is feasible and hypothetically superior to fluoroscopy in such circumstances., Competing Interests: The authors declare that there are no conflicts of interest., (Copyright © 2021 Seyed Hassan Inanloo et al.)

Indicators can help decision-makers evaluate interventions in a complex, multi-sectoral injury system. We aimed to create indicators for road safety, seniors falls, and 'all-injuries' to inform and evaluate injury prevention initiatives in British Columbia, Canada. The indicator development process involved a five-stage mixed methodology approach, including an environmental scan of existing indicators, generating expert consensus, selection of decision-makers and conducting a survey, selection of final indicators, and specification of indicators. An Indicator Reference Group (IRG) reviewed the list of indicators retrieved in the environmental scan and selected candidate indicators through expert consensus based on importance, modifiability, acceptance, and practicality. Key decision-makers ( n = 561) were invited to rank each indicator in terms of importance and actionability (online survey). The IRG applied inclusion criteria and thresholds to survey responses from decision-makers, which resulted in the selection of 47 road safety, 18 seniors falls, and 33 all-injury indicators. After grouping "like" indicators, a final list of 23 road safety, 8 seniors falls, and 13 all-injury indicators were specified. By considering both decision-maker ranking and expert opinion, we anticipate improved injury system performance through advocacy, accountability, and evidence-based resource allocation in priority areas. Our indicators will inform a data management framework for whole-system reporting to drive policy and funding for provincial injury prevention improvement.

Resistance to care is among the most common behaviors exhibited by persons with dementia (PwD). Resistance to care is a barrier to safety and comfort of PwD and caregivers. Nonpharmacological interventions are recommended as first-line management. In the current study, 13 long-term care (LTC) residents aged 74 to 100 years with a history of behavioral and psychological symptoms of dementia (BPSD) were randomized to intervention ( n = 7) and control ( n = 6) groups. On Days 1 to 3, the intervention group received usual care plus exposure to MindfulGarden (MG), a novel digital calming device during morning and evening care, activities widely recognized as problematic for PwD and staff; the control group received usual care only. On Day 4, both groups were exposed to MG with verbal prompting. Trends in the data suggest that MG reduced BPSD and duration of care in the morning and may be a useful tool in management of resistance to routine care in PwD in LTC settings.

Background: Evidence concerning the impact of long-term exposure to fine Particulate Matter ≤2.5 μm (PM 2.5 ) on Cardio-Vascular Diseases (CVDs) for those people subject to ambient air pollution in developing countries remains relatively scant. This study assessed the relationship of 15-year PM 2.5 exposure with cardiovascular incidence and mortality rate in Isfahan province, Iran., Methods: The cohort comprised 3081 participants over 35 years old who were free of CVDs. They were selected through multi-stage cluster sampling in Isfahan, Iran. PM 2.5 exposure was determined separately for each individual via satellite-based spatiotemporal estimates according to their residential addresses. In this context, CVD is defined as either fatal and non-fatal Acute Myocardial Infarctions (AMI) or stroke and sudden cardiac death. The incidence risk for CVD and the ensuing mortality was calculated based on the average PM 2.5 exposure within a study period of 15 years using the Cox proportional hazards frailty model upon adjusting individual risk factors. The mean annual rate of PM 2.5 and the follow-up data of each residential area were combined., Results: Mean three-year PM 2·5 exposure for the cohort was measured at 45.28 μg/m 3 , ranging from 20.01 to 69.80 μg/m 3 . The median time period for conducting necessary follow-ups was 12.3 years for the whole population. Notably, 105 cardiovascular and 241 all-cause deaths occurred among 393,786 person-months (27 and 61 per 100,000 person-months, respectively). In well-adjusted models, 10 μg/m 3 increase in PM 2.5 corresponded to a 3% increase in the incidence rate of CVDs [0.95 CI = 1.016, 1.036] (in case of p = 0.000001 per 10 μg/m 3 increase in PM 2.5 , the Hazard Ratio (HR) for AMI and Ischemic Heart Disease (IHD) was 1.031 [0.95 CI = 1.005, 1.057] and 1.028 [0.95 CI = 1.017, 1.039]), respectively. No consistent association was observed between PM 2.5 concentration and fatal CVD (fatal AMI, fatal stroke, SCD (Sudden Cardiac Death)) and all-cause mortality., Conclusions: Results from analyses suggest that the effect of PM 2.5 on cardiovascular disease occurrence was stronger in the case of older people, smokers, and those with high blood pressure and diabetes. The final results revealed that long-term exposure to ambient PM 2.5 with high concentrations positively correlated with IHD incidence and its major subtypes, except for mortality. The outcome accentuates the need for better air quality in many countries., (© 2021. The Author(s).)

Substantial efforts devoted to decreasing the burden of transport-related injuries (TRIs) in Canada, including public awareness campaigns aiming to influence attitudes and behaviors, may lead the public to perceive other types of injuries differently. This study examined the relationship between public perception of the preventability of injuries and the type of injury (TRIs vs. non-transport unintentional injuries (NTUIs)); and assessed whether exposure to a social marketing campaign ( Preventable ) influenced this association. A cross-sectional study design employed survey data collected by Preventable between 2015 and 2016 from 1501 British Columbians aged 25-54 years. A multiple linear regression model was applied to examine the relationship between the type of injury (TRIs vs. NTUIs) and attitudes towards preventability, controlling for socio-demographic variables. Exposure to the campaign was tested as an effect modifier. On a scale from 1 to 10, respondents perceived TRIs to be 1.08 points more preventable than NTUIs (95% CI: 1.00 to 1.16, p -value < 0.0001). Campaign-exposed participants scored 0.31 points higher on preventability of injuries overall (95% CI: 0.16 to 0.47, p -value < 0.0001); and recorded a smaller difference between the perceived preventability of TRIs and NTUIs, relative to those not exposed to the campaign (B = -0.163, 95% CI: -0.28 to -0.04, p -value = 0.008). While respondents believed that most injuries are preventable, exposure to considerable road traffic interventions in Canada may have influenced public attitudes towards a higher perceived preventability of TRIs. Social marketing may be a useful tool to emphasize the preventability of all injuries to further reduce their burden in Canada.

The purpose of this commentary is to discuss how legalization of non-medical marijuana (LNMM) in Canada can potentially influence child and adolescent unintentional injuries based on evidence from states (American) and jurisdictions that have already legalized cannabis for recreational purposes. Although the evidence is still not conclusive, LNMM can bring about higher exposure, lower perceived harms, and higher prevalence of cannabis use by minors through role modeling and normalization of behaviour within the household and the community, and higher rates of driving under the influence of cannabis, which can contribute to a higher burden of road traffic injuries. Experience of American states with LNMM shows higher rates of emergency visits for pediatric poisoning due to unintentional ingestion of cannabis-containing foods and severe burns due to explosions during the course of home-based cannabis extraction. While the justification for legalization has created a strict legal framework for improved control of cannabis in Canada, the implications for health and safety of children and adolescents necessitate further study, communication with policy-makers and public health practitioners, and evidence-based education of parents, caregivers, and youth.

Objectives: Social Stigma is potentially a major problem in multiple sclerosis patients which strongly affects the quality of life. The aim of this study was to determine the prevalence of perceived stigma in patients with MS in a sample of Iranian population., Methods: This cross-sectional study was performed on 305 MS patients who were referred to Iranian Multiple Sclerosis Society in 2014. The main variables were perceived stigma, age, sex, marital status, educational level, occupation, duration of the disease, type of symptoms, disability expanded status scale, family history and economic status. Social stigma was measured through a 20-item questionnaire which was developed by authors and the reliability was assessed in a pilot study., Results: The frequency of perceived stigma was significantly associated with occupation, disease duration, and visibility of symptoms, level of disability and the economic condition. There were no significant relationships between perceived stigma and age, sex, marital status, level of education and family history. About 44 percent of patients preferred to hide their disease from others and 52.6 percent believed that this disease would stigmatize them in society. Nearly, half of patients preferred not to mention their disease in job interviews., Conclusion: Recognition of the impacts of perceived stigma on various aspects of the patients' lives are necessary to find appropriate strategies to deal with stigma and its consequences. Training programs can improve the patients' skills for coping with stigma. Furthermore, programs aimed to upgrade public knowledge and reduce the negative attitudes toward the disease should be promoted.

Background and Aim: Driving after a night shift imposes a risk on health care professionals and other road users. The aim of this study was to measure psychomotor performance of driving of night shift nurses compared to day-shift nurses., Methods: Forty-seven volunteer female nurses working at Sina hospital in Tehran, Iran, with a call in all departments of hospital, participated in this study (23 night shift and 24 day shift nurses) in 2016. The tests included RT for simple reaction time, ATAVT for perceptual speed, LVT for visual orientation and ZBA for time anticipation. Data collection tools were individual characteristics, 11-item circadian type inventory (CTI), Stanford sleepiness scale (SSS), and Swedish occupational fatigue inventory (SOFI-20) questionnaires. Psychomotor driving performance was assessed using validated computerized traffic psychological battery of Vienna Test System (VTS), before and after the shifts. Data analysis was performed using paired-samples t-test and Linear Regression., Results: The mean age of day and night-shift nurses were 31.4±5.6 and 28.7±3.9 years respectively, no significant difference between two groups. Thirty percent of night shift and 16.7% of day shift nurses reported traffic accidents in the past year. The results revealed that, scores based on viewing times in visual orientation test (p=0.005), and median reaction time score in choice reaction time and reactive stress tolerance test (p=0.045), had a significant association with a 12-hour night shift with a 3-hour nap., Conclusions: Twelve-hour night shift work impairs choice reaction time and visual orientation in nurses, even though they take a 3- hour nap during the shift. These skills are required for safe driving., Competing Interests: Conflict of Interest: There is no conflict of interest to be declared.

Introduction: The aim of this study was to compare serum vitamin D between fertile and infertile men in endemic area of vitamin D deficiency. The role of vitamin D in all aspects of human health has attracted a great interest. Vitamin D effect on female fertility and to a lesser extent in men is under investigation. Previous researchers have found meaningful positive relationship between semen quality and serum vitamin D level. However, in endemic area of vitamin D deficiency, this effect is under question., Methods: Serum 25-OH-Vitamin D was compared between infertile male patients and fertile control group.Infertile cases were from patients of our infertility clinic and fertile controls from healthy cases with at least one child below 5 years of age.SPSS version 19 was used for statistical analysis (Kolmogorov-Smirnov test and Mann-Whitney test)., Results: Between 116 fertile and 114 infertile men who entered the study, serum level of 20 was a critical point, which patients with upper serum level had significantly better spermogram. In addition to it, even in vitamin D deficient patients and controls, fertile controls had higher serum vitamin D., Conclusions: There is a positive correlation between serum level of vitamin D and spermogram quality, even in vitamin D deficient areas. Fertile people have a higher level of serum vitamin D in comparison to infertile patient in aforementioned areas.

Background: Adolescence is the age of increased sensation-seeking and risk-taking. To prevent such behaviors, the adolescent tendency to engage in high-risk behaviors must be measureable. This study aimed to develop a questionnaire about risk-taking tendencies among Iranian students., Methods: This study was conducted using cluster sampling of the tenth-grade students in three cities in Kerman province, Iran. The students were assured that the questionnaires would remain anonymous and unlinked. Construct validity was assessed using exploratory factor analysis (EFA) and comparison of known groups. Corrected item-scale correlation and Cronbach's alpha were calculated to evaluate reliability., Findings: A total of 551 high school students participated in this study. Of these, 57 were excluded after checking the "non-existent drug" item (10.3%). Girls accounted for 49.2% of the sample. Of the 33 initial questions, 13 were removed due to factor loading of less than 0.5. Two factors were extracted using the scree plot ("drug abuse tendency" and "other risky behavior tendency"). The tendency toward high-risk behavior was significantly higher in male students than in female ones (P < 0.001). This indicates the known group validity of the questionnaire. The Cronbach's alpha of the above-mentioned factors were 0.93 and 0.83, respectively., Conclusion: The questionnaire measuring the tendency toward high-risk behavior among students showed acceptable validity and reliability.

Background: Vitiligo is a multi-factorial pigmentary skin disorder. Recently, the importance of emotional and psychological issues is proposed in incidence, progression, relapse and remission of vitiligo. There are limited studies conducted in developing countries, which assess life quality of patients with vitiligo. The aim of this study was the application and evaluation of a disease-specific quality of life index in Iranian patients, for the first time., Methods: This cross-sectional biphasic study was conducted on 25 patients as a pilot and another 173 patients as the main study group, in Razi Hospital, Tehran, Iran, 2013-2014. Persian version of Vitiligo Quality of Life index (VitiQoL) was developed with backward-forward method. Based on the pilot study, the validity and reliability were assessed. The Vitiligo Area and Score Index (VASI), VitiQoL, and their relationship, demographic and clinical characteristic of patients were measured., Results: The Mean and standard deviation of the VitiQoL score was 30.5 ± 14.5 (range 0-60 in Persian version). There was a significant relationship between VASI score and VitiQoL (p = 0.015, r = 0.187). Confirmatory factor analysis revealed three important factors within VitiQoL: participation limitation, stigma, and behavior. In subscale analysis based on behavior factor, female patients had poorer quality of life (p = 0.02). Concomitant psychiatric problems, e.g. anxiety and depression, were not associated with QOL; however, they were near to being meaningful (p = 0.06, r = 0.14)., Conclusion: VitiQoL is a valid index in estimating life quality of vitiligo patients and has proper relation to disease severity. Focusing on patient's life quality is an important entity in the management of vitiligo patients; relevant supportive group-based consultations and therapies are also important arms when approaching vitiligo.

Purpose: The purpose of this paper is to identify the main reasons for discharge against medical advice (DAMA) in the emergency department (ED) of a teaching hospital in Tehran, Iran., Design/methodology/approach: This cross-sectional study was conducted on all the patients who left the ED of a referral teaching hospital against medical advice (AMA) in 2008. A questionnaire was filled out for each patient to determine the reasons behind patient leaving AMA., Findings: In total, 12.8 percent of the patients left the hospital AMA. Dissatisfaction with being observed in the ED, having a feeling of recovery and hospital personnel encouraging patients to leave the hospital were the main reasons for leaving the hospital AMA., Practical Implications: Like many other centers, the results showed that poor communication skill and work overload were the main contributing factors to DAMA. The center managed to improve patient satisfaction and thus lowered DAMA rates following this study. Considering the similarities reported in the reports and that of other studies, it could be concluded that policy makers in other centers can also benefit from the results to adopt effective approaches to reduce DAMA rate., Originality/value: To the knowledge no study has evaluated the rate and the reasons behind DAMA in the Iranian EDs.

Despite the strong evidence of child safety seats (CSSs) effectiveness in reducing injuries, it is still rarely used in some societies. The purpose of this study was to determine prevalence and predictors of CSS use in Mashad, Iran. Five hundred ninety kindergarten children whose parents owned a car were enrolled in the study. Parents were asked about using CSS for their children, reasons for CSS use/non-use, demographics, history of road traffic injuries and receiving any advice on CSS. Of families, 25.5% expressed that they used CSS for their child at present or any time in the past, but only 6.3% of children travelled restrained in CSS at the time of study. Age-appropriate CSS use was reported in 14.5% of infants and 2.3% of 1-5-year-old children. A significant relationship was observed between lower child age, higher maternal education and high family income with CSS use. The main reasons for CSS none-use were reported as not feeling the need (42%), followed by its high price (22%). Use of CSS was uncommon. The financial concerns and information gap about the essential need for CSS should be considered as priorities for action especially among lower socio-economic groups of society.

Neuroblastoma is the most common extracranial solid tumor of children, accounting for an estimated 15% cancer-related deaths in this period. It has been hypothesized that drug resistance of cancer stem cells may be responsible for chemotherapy failure, sustained tumor growth, and recurrence in many solid tumors. In this study, we investigated the expression of Octamer-binding transcription factor 4 (Oct4) and Nanog, two stem cell markers, in 47 neuroblastic tumors by immunohistochemistry and correlated their expression by other prognostic factors especially with NMYC amplification using both fluorescent and chromogenic in situ hybridization methods. Twenty three cases (48.9%) showed Oct4 signals and eight cases (17%) showed Nanog expression. All Nanog positive tumors showed Oct4 expression. Seven cases (14.1%) had NMYC amplification. There was also no association between positive Oct4 and Nanog reactivity and tumor morphology, age, mitosis-karyorrhexis index, NMYC amplification, favorable or unfavorable histology, and risk groups (p > 0.05). Cancer stem cells hypothesis is a challenging issue and controversies exist about their significance. Although our study did not show strong association between prognostic factors and expression of stem cell markers, performing of further large-scale studies of various neuroblastic tumors with various stages is suggested., (© 2013 APMIS.

Background: Radon exposure is the second cause of lung cancer after exposure to tobacco smoke and the first cause in nonsmokers. The purpose of this study was to assess perceived risk of exposure to indoor residential radon among health care providers in urban and rural health centers affiliated to Tehran University of Medical Sciences., Method: In 2012-2013, a survey was carried out on 462 health care providers to assess their awareness and risk perception about exposure to indoor residential radon. Only subjects who had previously heard about radon were asked to answer knowledge-based and risk perception questions and report source of knowledge, willingness to test and willingness to pay for radon test kits., Results: About 67% of responders had heard about radon before this study and of these, 83.5 % recognized it as being hazardous and 34.5 % identified lung cancer as the main health outcome of exposure to radon. Overall, 33% of 310 subjects had knowledgeable awareness. Seventy percent of responders who had previously heard about radon, had high perceived risk and they were more willing to test their houses and more willing to pay for radon test kits., Conclusion: Having knowledge about radon and perceiving it as a risk had a significant association with willing to take relevant health related behaviors. Furthermore, risk perception contributes to willing to spend more money when health is a concern. Education of health care providers seems to be a pre-requisite to public campaigns on radon awareness and testing.

Controlling blood pressure in hemodialysis patients is crucial but not always easy. The most common blood pressure measurement method is peri-dialysis measurement, but due to interdialytic blood pressure fluctuations, we are unsure if it is the proper way for evaluating blood pressure. Some studies have shown the superiority of 24-h ambulatory blood pressure monitoring over peri-dialysis blood pressure measurement. We aimed to compare the consistency of these methods in determining hypertension among hemodialysis patients. We studied 50 patients (mean age: 55.8 years) on regular hemodialysis in Imam Khomeini University Hospital, Tehran, Iran. Peri-dialysis blood pressure and interdialytic 24-h ambulatory blood pressure monitoring were recorded for each patient. Patients' demographic data and peri-dialysis weight were recorded too. All data were analyzed using the PASW Statistics 18.0, SPSS Inc. (Chicago, IL). There was a significant difference between pre-dialysis mean systolic blood pressure (146.1 ± 23.3 mmHg) and mean systolic blood pressure recorded by ambulatory blood pressure monitoring (135.3 ± 19.3 mmHg) (p = 0.001). There was also a significant difference between pre-dialysis mean diastolic blood pressure (83 ± 14 mmHg) and mean diastolic blood pressure recorded by ambulatory blood pressure monitoring (77.3 ± 10 mmHg) (p = 0.003). But the frequencies of hypertension measured with both methods were significantly consistent and the Kappa agreement coefficient was 0.525 (p = 0.001). Considering ambulatory blood pressure monitoring as the gold standard for blood pressure measurement, our recommendation for the best cutoff point to diagnose hypertension, with the highest sensitivity and specificity would be 135/80 mmHg for pre-dialysis blood pressure and 115/70 mmHg for post-dialysis blood pressure.
