Background: Beyond alcohol retail establishments, most business and property types receive limited attention in studies of violent crime. We sought to provide a comprehensive examination of which properties experience the most violent crime in a city and how that violence is distributed throughout a city.

Methods: For a large urban city, we merged violent incident data from police reports with municipal tax assessor data from 2012-2017 and tabulated patterns of violent crime for 15 commercial and public property types. To describe outlier establishments, we calculated the proportion of individual parcels within each property-type that experienced more than 5 times the average number of crimes for that property-type and also mapped the 25 parcels with the highest number of violent incidents to explore what proportion of violent crime in these block groups were contributed by the outlier establishments.

Results: While the hotel/lodging property-type experienced the highest number of violent crimes per parcel (2.72), each property-type had outlier establishments experiencing more than 5 times the average number of violent crimes per business. Twelve of 15 property-types (80%) had establishments with more than 10 times the mean number of violent incidents. The 25 parcels with the most violent crime comprised a wide variety of establishments, ranging from a shopping center, grocery store, gas station, motel, public park, vacant lot, public street, office building, transit station, hospital, pharmacy, school, community center, and movie theatre, and were distributed across the city. Eight of the 25 parcels with the highest amount of violent crime, accounted for 50% or more of the violent crime within a 400-meter buffer.

Conclusions: All property-types had outlier establishments experiencing elevated counts of violent crimes. Furthermore, the 25 most violent properties in the city demonstrated remarkable diversity in property-type. Further studies assessing the risk of violent crime among additional property-types may aid in violence prevention.

Background: The purpose of this study was to analyze the co-occurrence of adult and child abuse based on the reports collected from the Polish police and social welfare institutions.

Methods: The study involved data concerning 468 households in Szczecin (Poland) inhabited by children where acts of violence between adults took place. The presented data refer to the years 2012-2103. The data came from so called Blue Card files, i.e. documents issued by the police and social workers in cases of domestic abuse, providing information about its forms, perpetrators, and victims.

Results: Domestic violence usually occurs between spouses and cohabitees (78%). The perpetrator was usually a man (88%). Violence usually lasted from 1 up to 3 years (30.0%). The most common forms of physical abuse against adults and children included pushing (79.5% of adults, 22.4% of children) and hitting (64.7% of adults, 16.6% of children), and psychologically abusive behaviors were mostly insults (91.9% of adults, 27.5% of children) and criticism (79.1% of adults, 21.5% of children). This work has shown that the longer the psychological abuse between adults lasts, the greater probability is that it will also be used against children. Child abuse is also associated with putting up resistance to the police by perpetrators.

Conclusions: Summing up, in households where violence between adults is observed, actions should be taken to prevent violence against children.

Background: The precision of emergency medical services (EMS) triage criteria dictates whether an injured patient receives appropriate care. The trauma triage protocol is a decision scheme that groups patients into triage categories of major, moderate and minor. We hypothesized that there is a difference between trauma triage category and injury severity score (ISS).

Methods: This retrospective, observational study was conducted to investigate a difference between trauma triage category and ISS. Bivariate analysis was used to test for differences between the subgroup means. The differences between the group means on each measure were analyzed for direction and statistical significance using ANOVA for continuous variables and chi square tests for categorical variables. Logistic and linear regressions were performed to evaluate factors predicting mortality, ICU length of stay.

Results: With respect to trauma triage category, our findings indicate that minor and moderate triage categories are similar with respect to ISS, GCS, ICU LOS, hospital LOS, and mortality. However, after excluding for low impact injuries (falls), differences between the minor and moderate categories were evident when comparing to ISS, GCS, ICU LOS, and hospital LOS. Additionally, after excluding for low impact injures, ISS, ICU LOS, and hospital stay were found to correlate well with trauma triage category.

Conclusions: In this retrospective, observational study significant differences were not seen when comparing ISS with the trauma triage categories of moderate and minor during our initial analysis. However, a difference was found after excluding for low impact injuries. These findings suggest that CDC criteria accurately predicts outcomes in high impact trauma.

Background: In recent decades, earthquakes, as natural hazards that caused direct effects both on communities and the chemical industry, produced many Natech events. Natech term is utilizing to describe the technological disasters caused by natural hazards. This study was conducted on the emergency evacuation challenges of residential areas adjacent to a refinery near Tehran based on H2S toxic gas release following a possible earthquake scenario.

Methods: This Research was an applied study at two phases in 2020. In the first phase, a review study was conducted to identify the community's previous experiences on emergency evacuation following Natech events. In the second phase, the challenges of emergency evacuation were analyzed based on the scenario of a possible earthquake and gas release from the refinery.

Results: Due to the high seismic vulnerability of structures in the area affected Natech risk, the total Resident population in this area would be affected simultaneously by an earthquake and H2S gas release in concentration 30 ppm as the result of the earthquake impact on chemical facilities. Emergency evacuation would be inevitable. The existing evacuation places are very unsafe and dangerous due to having open spaces. The nearest suitable evacuation places were found in the north direction for more than 38 % of the exposed population and in the east, west, and south direction for more than 61% of them.

Conclusions: The emergency evacuation challenges were discussed in 4 viewpoints, disrupted or interrupted rescue and firefighting operation, unnecessary evacuation, frequent evacuation, and evacuation behavior. The measures such as revising and updating emergency evacuation maps; public informing, training, preparedness; providing protocols and training for operational and therapeutic response teams; and coordination improvement can help resilience increasing to such disasters.

Background: According to the World Health Organization, occupational injuries are significant health issues globally that affect social lives and economic status. This study aimed to assess the situation of occupational injuries in the Kerman province.

Methods: In this cross-sectional study, all occupational injuries registered in the Department of Cooperatives Labor and Social Welfare of Kerman Province were investigated during 2012-2016. Data were retrieved from an institutional database, including the official institutional software reports of Cooperatives Labor and Social Welfare occupational inspectors. The study used ArcGIS 10.3 software to prepare the geographical distribution of the cumulative incidence of occupational injuries on the map for each city. Data were analyzed using SPSS software.

Results: A total of 2228 subjects with a mean age of 34 years and a mean work experience of 4.5years were injured during 5 years. 73.2% of them were married. 96.4% of them were Iranian, and 61.3% had insurance. The most number of injuries occurred in the construction industry, fractures being the typical outcome of the injuries. The most injured organ was the hands. Kerman has the highest number of injuries with 804 cases. Incidence rates ranged was 93 to 138 cases per 100,000 people in 5 years. The highest cumulative incidence rates of accidents occurred in Zarand and Kahnuj, respectively, in 5 years.

Conclusions: Despite the decrease in occupational injuries in recent years, it is a severe problem in Kerman province. Occupational injuries cause irreparable damages to human resources, and it, directly and indirectly, imposes costs for the family and the government. Therefore, considering safety in occupational environments to prevent occupational injuries should be a priority in planning.

Background: Road traffic injuries (RTIs) have been eighth leading cause of death in the world and second leading one Iran in 2018. Every year, a large number of motorcycle RTIs lead to deaths and disabilities due to non-compliance with traffic rules and the traditional design of the streets and routes in Dezful, Iran. This study aims to pursue two goals: identifying the legal and environmental factors affecting motorcycle RTIs, and prioritizing effective strategies in reducing number of motorcycle RTIs in Dezful, Iran.

Methods: A mixed method approach was used in this study. In the qualitative phase, focus group meetings using key informants were used to identify the effective factors and in the quantitative one a matrix was used for prioritizing effective strategies in preventing motorcycle RTIs.

Results: 45 basic codes related to legal factors and 8 basic codes of environmental factors were derived from the focus group meetings. Six main legal factors and 3 main environmental factors were prioritized as the most effective strategies to reduce motorcycle RTIs. The legal factors with the highest score were: making visible: obstacles, motorcycles and pedestrians and motorcyclists using colors and stickers or glossy stickers, further monitoring and training of riders' license issuance schools, seriousness in enforcing the laws and dealing legally and seriously with violators, continuous marking of roads and streets, random check of motorcycle riders' license, and construction of public parking lots in crowded zones. The environmental ones were: identifying places where traffic signs are covered with trees, and reporting through the 137 call center, identifying and reporting shoulderless and hazardous roads by municipality, and Identifying and reporting accident-causing potholes through the 137 call center.

Conclusions: All organizations and stakeholders involved in reducing motorcycle RTIs, should take benefit from different recommendation - i.e. education & awareness, law enforcement and legal actions, environmental actions, collaborations, partnerships, and lobbying, and research.

Background: In the U.S., drowning is a leading cause of death for toddlers. One important layer of protection against submersion injuries and fatalities is parent or caregiver supervision. The aims of this study are to explore current supervisory behavior of caregivers, determine how caregivers view com-mon supervision distractions, like cell phones and grilling, and identify what factors shape the quality of supervision that is given when swimming with their toddler at a swimming pool.

Methods: This cross-sectional study used the MTurk online platform to survey 650 caregivers of toddlers (1-4 yrs old) about their supervision behavior, their drowning knowledge, their perceptions of arm's reach supervision, the water competency of their toddler, and other background information. Regression analysis was used to identify factors that predicted report-ed supervision behavior.

Results: The average supervision behavior score for caregivers indicated an attitude between neutral and disagreement with allowing distractions for themselves while supervising their toddler in a swimming pool. High water safety knowledge and positive perceptions of arm's reach supervision were the biggest predictors of attentive supervision behavior. Having a home pool, higher education level, and believing their toddler had greater water competency were predictive of less attentive supervision behavior.

Conclusions: Results suggest that supervision behavior while toddlers are in a swimming pool may be inade-quate. Low water safety knowledge and attitudes about what constitutes quality supervision are related to pool supervision behavior and changing these may reduce drowning risk. Caregivers should be encouraged to not reduce supervision as their toddlers gain water competency and if they have a home pool.

Background: Organophosphate (OP) insecticides are important compounds as the most probable common cause of acute poisonings in developing countries. OP intoxication often presents as medical emergencies, and its related morbidity and mortality have not decreased despite major advances in critical care. This study aims to determine the impact of serum amylase level for estimation of prognosis in patients with acute OP poisoning.

Methods: This observational case-control study was done during two years on 332 consecutive patients with acute OP poisoning. Clinical and demographic data, serum amylase level on early admission time, morbidity, and outcome were determined. Data were analyzed in the form of a frequency distribution table by using SPSS 11.0 version software.

Results: The mean age of patients with acute OP poisoning was 28.9 ± 23.95 with slightly female dominance. All patients were intoxicated via the gastrointestinal route. The mean amylase level of patients with deterioration of mental status, tachycardia, ICU admission, and death was significantly higher.

Conclusions: Among patients with OP poisoning, higher serum amylase than normal was associated with severe clinical course and increased risk for mortality. Determination of serum amylase can be effective in the quick prediction of the outcome.

Background: Sufficient data should be gathered and analyzed to increase awareness and attention of the community and policymakers in the field of road traffic injury (RTI) prevention. While various organizations and stakeholders are involved in road traffic crashes, there is no clear lead agency for data collection system in RTIs. Exploring stakeholders' perspective is one of the key sources for understanding this system. The purpose of this study is to identify the process of RTI data collection system based on stakeholders' experience.

Methods: This qualitative study was conducted employing grounded theory approach since September 2017 to December 2018 in Iran. Participants in this study were the authorities of the Emergency organizations, police, Ministry of Health and Medical Education, faculty members, as well as executive staff and road users who were involved in collecting and recording data (n=15). Data collection was carried out through face-to-face interviews using purposeful and theoretical sampling. Data analysis was performed based on Strauss and Corbin 2008.

Results: The core category was identified as "separated registration" explaining the process of collecting and recording road traffic injury data. Other variables obtained using the Strauss and Corbin Paradigm model were categorized as context, casual, intervening, strategies, and outcomes factors. The findings were classified into five groups including lack of trust in road safety promotion, process factors, management and organizational factors, failure of quality assurance, and administrative and organizational culture.

Conclusions: The most important theory is "separated registration" and non-systematic registry system of road traffic injury data which is shown in a conceptual model. The findings of this study will help policymakers for better understanding the collecting and recording of RTI information.

Background: This study utilized videos from a child's and an adult's perspective to determine whether perspective influences the number of hazards identified by parents.

Methods: The study measured number of household dangers parents' identified. Parents (n=106) were randomized to view either the child or adult perspective videos. Groups did not differ with respect to median age (p=0.51), education (p=0.55), or number of children living at home (p=0.64).

Results: Median number of hazards identified in the bedroom was 3 for participants watching videos taken at either adult or child perspective (p=0.32). Parents viewing child perspective videos of the kitchen identified significantly more hazards (median=4) than parents viewing adult perspective videos (median=3) (p=0.0001).

Conclusions: Although video height (perspective) did not influence the number of hazards identified in the bedroom, parents who observed the kitchen video taken at a child's height identified more hazards than those viewing a video at adult height.
