[PMID: 39281490 PMCID: PMC11401119 DOI: 10.1016/j.heliyon.2024.e36584] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2024] [Revised: 08/14/2024] [Accepted: 08/19/2024] [Indexed: 09/18/2024] Open
Abstract
The treatment of chronic burn wounds is difficult in clinical practice. The ideal therapy is required to be continuously explored. Mesenchymal stem cells revolutionize the treatment of many diseases. The placental mesenchymal stem cells (PMSCs) have the characteristics of easy access, strong proliferation ability and multi-directional differentiation potential. The aim of this study was to investigate the potential of PMSCs in chronic burn wound healing. In this study, species of bacteria of 317 patients with chronic burn wounds have been analyzed. Samples of chronic burn wound fluid were collected from representative patients and then co-cultured with cells. In vitro studies showed that chronic burn wound fluid inhibited the proliferation of human keratinocytes and fibroblasts, while PMSCs can counteract the effects of burn wound fluid on inhibiting the proliferation and migration of human keratinocytes and fibroblasts. In addition, in vivo studies showed that a rat chronic burn wound model was successfully created. The expression of MMP-2, MMP-9, MDA, IL-6 and TNF-α in chronic burn wounds was significantly higher than that in acute burn wounds. Finally, the rat chronic burn wound model was used to verify that placental mesenchymal stem cell transplantation increased the wound healing rate, decreased the wound healing time, and promoted wound healing by increasing the thickness of epidermis and promoting the expression of P63 and CK10. The findings provide support for the hypothesis that PMSCs promote the repair of chronic burn wounds and key scientific data for the application of PMSCs as a new method for treating chronic burn wounds.

Abstract
On June 13, 2020, a liquefied petroleum gas tanker exploded in Wenling. Here, the authors describe the mass casualty emergency response to the explosion. The authors collected the medical records of 176 inpatients at 8 hospitals in Taizhou and Hangzhou. The 176 inpatients with blast injuries comprised 70 females and 106 males, with an average age of 45.48 ± 19.96 years, and more than half of the patients were farmers. They were transported to six hospitals distributed around the explosion site in Taizhou in the initial rescue period and were grouped according to their new injury severity score as having mild, moderate, severe, or extremely severe injuries. Most patients with severe and extremely severe injuries were admitted to a superior hospital for postsecondary triage. Forty-four patients experienced primary blast injuries, 137 experienced secondary blast injuries, 37 experienced tertiary blast injuries, and 40 patients experienced quaternary blast injuries. Multiple blast injuries were suffered by 62 patients. Most patients (95.45%) suffered external injuries, with the chest, extremities, and face as the main affected areas. Burns were diagnosed in 26 adults, of whom 15.38%, 19.23%, 7.70%, and 57.69% suffered mild, moderate, severe, and extremely severe cases. Sixteen burn patients suffered from burn-blast injuries. Upper limbs and the head/face/neck area, as exposed areas, were more likely to experience a burn injury. Inhalation was the main accompanying injury. Of the eight patients who died in the prehospital session, seven had burn injuries. This report on the accident and injury characteristics of an open-air LPG-related explosion will facilitate responses to subsequent catastrophes.

Abstract
Objectives This study aims to describe the injury patterns of the Beirut blast victims and assess hospitals' disaster management and preparedness during the 2020 Beirut port blast. Methods A cross-sectional retrospective multicenter study was conducted in two stages. Data were collected on blast victims presented to participating hospitals from August 4 till August 8, using three designed questionnaires. Stage 1 included all blast patients' records and stage 2 examined a subset of inpatient and outpatient records. Binary logistic regression was performed to assess the factors associated with death and disability for blast patients. Results A total of 3278 records were collected, 83% were treated at emergency departments and 17% were admitted to hospitals. Among those, 61 deaths and 35 long-term disabilities were reported. Extremity operations (63%) were mostly performed. Outpatients (n=410) had a mean age of 40±17.01 years and 40% sustained lacerations (40%). 10% of those patients sustained neurological complications and mental problems, and 8% had eye complications. Inpatients (n=282) had a mean age of 49±20.7 years and a mean length of hospital stay of 6±10.7 days. Secondary (37%) and tertiary (25%) blast injuries were predominant. 49% sustained extremity injuries and 19% head/face injuries. 11 inpatient deaths and 20 long-term disabilities were reported. Death was significantly associated with tertiary concussion and crush syndrome (p<0.05). Of the 16 hospitals, 13 implemented disaster plans (87%), and 14 performed a triage with a mean time of 0.96±0.67 hours. One hospital (6%) performed psychological evaluations, without follow-up. Conclusion Beirut blast victims suffered deaths and disabilities associated with their injuries. They predominantly sustained lacerations caused by shattered glass. Tertiary injuries were associated with death. Triage, disaster plans, and hospital preparedness should be effectively implemented to enhance patients' clinical outcomes. Level of evidence Prognostic and epidemiological/Level III.

Abstract
INTRODUCTION The incidence of blast injuries on the battlefield has risen over the last several decades. In order to improve prevention and treatment, it is essential to understand the severity and bodily distribution of these injuries. This study aims to characterize blast injury patterns among IDF fatalities. MATERIALS AND METHODS This is a descriptive, retrospective study on postmortem reports of military-blast fatalities between the years 1982 and 2021. Body regions injured according to the Abbreviated Injury Scale (AIS) were described. The frequency of body region injury combinations was mapped, and the correlation between injured body regions was calculated using Pearson's coefficient. Analysis of a subgroup with a postmortem computed tomography (CT-PM) or autopsy was performed, describing severe (AIS ≥ 3) injury patterns. RESULTS Overall, 222 fatalities suffered from blast injury, with most injuries affecting the upper and lower extremities (63.7% and 66.5%, respectively), followed by the head (57.1%) and the thorax (56.6%). The median number of injured body regions was 4 (interquartile range, 2-5). The most frequent injury combinations were the upper and lower extremities (51%), the upper extremities and the thorax (45%), and the lower extremities and the thorax (41%). In all, 47/222 (21.2%) fatalities had a documented autopsy or CT-PM report. Among the fatalities with CT-PM or autopsy, the head (63.8%) and the thorax (57.4%) were most frequently severely injured (AIS ≥ 3). CONCLUSIONS Among blast fatalities in the military setting, the extremities were most commonly injured. However, data suggest that the head and thorax are more likely to sustain severe blast injuries resulting in mortality. Blast injuries in this cohort were characterized by concomitant involvement of several regions. Development of protective gear to minimize the multisystem injuries inflicted by blast injuries is warranted and should be focused on distinct types and anatomical distribution of severe blast injuries as reported in this study. LEVEL OF EVIDENCE Level III, Retrospective analysis.

Abstract
Background Mass burn casualties impose an enormous burden on triage systems. The triage capacity of the Braden Scale for detecting injury severity has not been evaluated in mass burn casualties. Material/Methods The New Injury Severity Score (NISS) was used to dichotomize the injury severity of patients. The Braden Scale and other potentially indicative measurement tools were evaluated using univariate analysis and multivariate logistic regression. The relationships between the Braden Scale and other continuous variables with injury severity were further explored by correlation analysis and fitted with regression models. Receiver operating characteristic (ROC) curve analysis was used to validate triage capacity and compare prognostic accuracy. Results A total of 160 hospitalized patients were included in our study; 37 were severely injured, and 123 were not. Injury severity was independently associated with the Numerical Rating Scale (adjusted OR, 1.816; 95% CI, 1.035–3.187) and Braden Scale (adjusted OR, 0.693; 95% CI, 0.564–0.851). The ROC curve of the fitted quadratic model of the Braden Scale was 0.896 (0.840–0.953), and the cut-off value was 17. The sensitivity was 81.08% (64.29–91.44%) and the specificity was 82.93% (74.85–88.89%). Comparison of ROC curves demonstrated an infinitesimal difference between the Braden Scale and NISS for predicting 30-day hospital discharge (Z=0.291, P=0.771) and Intensive Care Unit admission (Z=2.016, P=0.044). Conclusions The Braden Scale is a suitable triage tool for predicting injury severity and forecasting disability-related outcomes in patients affected by mass burn casualty incidents.

Abstract
Lebanon is a middle-income country that has been recently crippled by several tragedies including the economic collapse, COVID-19, and the fourth of August Beirut port explosion, the world's most powerful non-nuclear explosion of the twenty-first century. Recent data on mental health from Lebanon is summarised, and other topics such as the psychological impact of cumulative adversities and the role of international support in Lebanon are examined. Data from Lebanon shows severe levels of distress among the people, in a country with minimal resources. Given current adversities in Lebanon, recent data in the country, and the literature on adversity and mental health outcomes of man-made disasters, Lebanon is most likely going to face an epidemic in poor mental health. A call is made for the wider scientific community and international organizations to support the mental health field in the country and help prevent further negative mental health outcomes. Understanding how to better navigate mental health in places with extreme adversity and emergencies can be beneficial to other communities which might face similar challenges.

Abstract
The increasing use and distribution of chemicals are causing serious chemical accidents such as fires, explosions, and leaks during manufacturing and handling. In most cases, all risks caused by chemicals are classified as accidents due to defects in process facilities, human errors, and multi-cause accidents. Among chemical accidents caused by human errors, accurate analysis of accidents caused by the complex action of various types of human failures is required. Based on the accident investigation reports that occurred in South Korea from 2010 to 2017, chemical accidents caused by human failure were analyzed, and the fundamental causes were derived by classifying them into human error and violation. Human failure was analyzed according to the classification criteria for human failure of health and safety executive (HSE). As a result of the analysis, several types of human failure acted in combination to be a more significant cause of chemical accidents; incorrect application of process rules and procedures, inappropriate chemical information, lack of education, and defects in the current safety regulation were analyzed as the main causes. In addition, the cause of human errors was presented through case studies of chemical accidents in South Korea.

Abstract
INTRODUCTION On the 4th of August 2020 an ammonium nitrate explosion took place at the Port of Beirut in Lebanon. The aim of this study was to present the open eye injuries caused by the Beirut Port blast, and to describe their characteristics and visual outcomes at 6 months. METHODS Patients who suffered from open globe injuries during the Beirut port explosion were recruited. Characteristics of the ocular injuries and best corrected distance visual acuity (BCVA) were recorded at presentation and at 6 months. RESULTS All included eyes (23 eyes of 19 patients) suffered from penetrating open globe injuries secondary to glass material and were operated by globe exploration + primary repair. Four of the 19 patients suffered from bilateral injuries none of whom suffered from legal blindness. BCVA at presentation was hand motion or worse in 21 of 23 eyes (91%). Seven of 23 eyes (30%) had expulsive loss of intraocular tissue, 4 of 23 eyes (17%) had retinal detachment and 4 of 23 eyes (17%) had traumatic cataracts. Ocular trama score (OTS) had a mean +/- standard deviation (SD) of 61 +/- 12. Eleven of 23 eyes (48%) had zone 2 ocular injuries and 10 of 23 eyes (43%) had zone 3 ocular injuries. At 6 months follow-up 15 of 23 eyes (65%) had a BCVA of less than 20/200. All patients with Grade 2 OTS, zone 3 injuries, expulsive loss of intraocular tissue and retinal detachment had BCVA of less than 20/200 at 6 months. CONCLUSION Open eye injuries secondary to explosions occur most frequently due to glass fragments. Most of the victims were indoors, near windows and less than 500m away of the explosion site at the time of the blast. The majority of victims have very low BCVA, a low OTS and a high ocular ZOI at presentation which reflects the danger of open globe injuries secondary to blasts. A high ZOI, a low OTS, the expulsive loss of intraocular tissue and retinal detachment seem to be predictors of worse VA at 6 months.

Abstract
A massive chemical detonation occurred on August 4, 2020 in the Port of Beirut, Lebanon. An uncontrolled fire in an adjacent warehouse ignited ~2,750 tons of Ammonium Nitrate (AN), producing one of the most devastating blasts in recent history. The blast supersonic pressure and heat wave claimed the lives of 220 people and injured more than 6,500 instantaneously, with severe damage to the nearby dense residential and commercial areas. This review represents one of the in-depth reports to provide a detailed analysis of the Beirut blast and its health and environmental implications. It further reviews prior AN incidents and suggests actionable recommendations and strategies to optimize chemical safety measures, improve emergency preparedness, and mitigate the delayed clinical effects of blast and toxic gas exposures. These recommended actionable steps offer a starting point for government officials and policymakers to build frameworks, adopt regulations, and implement chemical safety protocols to ensure safe storage of hazardous materials as well as reorganizing healthcare system disaster preparedness to improve emergency preparedness in response to similar large-scale disasters and promote population safety. Future clinical efforts should involve detailed assessment of physical injuries sustained by blast victims, with systemic mitigation and possible treatment of late blast effects involving individuals, communities and the region at large.

Abstract
BACKGROUND The protective role of helmet accessories in moderating stress load generated by explosion shock waves of explosive devices is usually neglected. OBJECTIVE In the presented study, the protective role of the helmet chinstrap against the impulse and overpressure experienced by the maxillofacial region were examined. METHODS The explosion shock wave and skull interaction were investigated under three different configurations: (1) unprotected skull, (2) skull with helmet (3) skull with helmet and chinstrap. For this purpose, a 3D finite element model (FEM) was constructed to mimic the investigated biomechanics module. Three working conditions were set according to different explosive charges and distances to represent different load conditions. Case 1: 500 mg explosive trinitrotoluene (TNT), 3 cm, case 2: 1000 mg TNT, 3 cm, and case 3: 1000 mg TNT and 6 cm distance to the studied object. The explosion effect was discussed by examining the shock wave stress flow pattern. Three points were selected on the skull and the stress curve of each point position were illustrated for each case study. RESULTS The results showed that the helmet chinstrap can reduce the explosive injuries and plays a protective role in the maxillofacial region, especially for the mandible.

Incidence, casualties and risk characteristics of civilian explosion blast injury in China: 2000-2017 data from the state Administration of Work Safety. Mil Med Res 2020; 7:29. [PMID: 32522241 PMCID: PMC7288536 DOI: 10.1186/s40779-020-00257-5] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/28/2019] [Accepted: 05/18/2020] [Indexed: 01/31/2023] Open
Abstract
BACKGROUND Civilian explosion blast injury is more frequent in developing countries, including China. However, the incidence, casualties, and characteristics of such incidents in China are unknown. METHODS This is a retrospective analysis of the State Administration of Work Safety database. Incidents during a period from January 1, 2000 to April 30, 2017 were included in the analysis. The explosions were classified based on the number of deaths into extraordinarily major, major, serious and ordinary type. Descriptive statistics was used to analyze the incidence and characteristics of the explosions. Correlation analysis was performed to examine the potential correlations among various variables. RESULTS Data base search identified a total of 2098 explosions from 2000 to 2017, with 29,579 casualties: 15,788 deaths (53.4%), 12,637 injured (42.7%) and 1154 missing (3.9%). Majority of the explosions were serious type (65.4%). The number of deaths (39.5%) was also highest with the serious type (P = 0.006). The highest incidence was observed in the fourth quarter of the year (October to December), and at 9:00-11:00 am and 4:00-6:00 pm of the day. The explosions were most frequent in coal-producing provinces (Guizhou and Shanxi Province). Coal mine gas explosions resulted majority of the deaths (9620, 60.9%). The number of explosion accidents closely correlated with economic output (regional economy and national GDP growth rate) (r = - 0.372, P = 0.040; r = 0.629, P = 0.028). CONCLUSIONS The incidence and civilian casualties due to explosions remain unacceptabe in developing China. Measures that mitigate the risk factors are of urgently required.

[PMID: 32375694 PMCID: PMC7203803 DOI: 10.1186/s12886-020-01448-3] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2019] [Accepted: 04/23/2020] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND To document characteristics and treatments of ocular blast injury from a fire and explosion. METHOD Authors retrospectively evaluated 116 patients with 166 eye injuries from six hospitals. Terminology of ocular injury referred to Birmingham Eye Trauma Terminology, and best-corrected visual acuity (BCVA) was categorized with the ocular trauma score (OTS) grading system. Incidence, preoperational and follow-up BCVA, treatment of severe ocular blast injuries were surveyed. RESULTS Oculoplastic injuries accounted for the majority of eye injuries, while globe injuries were presented in 52 eyes with median baseline OTS 70 ranging from 26 to 100. No endophthalmitis occurred. The mean timing of the first-stage operations was 9.4 ± 6.4 h after blast, while second-stage operations were performed on average 14.7 ± 0.9 days post blast. Final BCVA of 68.8% of eyes achieved 20/200 or better as followed, 7 open globe injuries had a BCVA of no light perception. Additionally, eyes presenting rupture, retinal detachment, vitreous hemorrhage, choroidal injury and initial BCVA less than 20/200 had worse final visual outcomes, while globe penetration was not associated with poor visual acuity. CONCLUSION Various ocular injuries were commonly in the casualties of blast, in which open-globe injuries have worst visual prognosis. OTS is a valid approach for evaluation of prognosis and optimizing the therapeutic strategies subsequently in the massive casualty. Intense rescue and careful examination, proper surgery should be performed correctly to rescue patients.

Risk Perception and Property Value: Evidence from Tianjin Port Explosion. SUSTAINABILITY 2020. [DOI: 10.3390/su12031169] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 11/16/2022]
Abstract
This paper aims to investigate the perceived risk after the Tianjin port explosion event and its impact on property value. In addition to focusing on the relationship between homebuyers’ risk perception and property sales price, this paper also considers the risk perception of property sellers via the sale-to-list ratio. By using the difference-in-differences method and the sample from the property agent, we found that the explosion event generated a long-time effect on the public and property market in the city of Tianjin. Relative to those properties far away from the explosion site, the sales price and the sale-to-list ratio of the property near the explosion site were detected to have significant drops for the first six months after the explosion event. The temporal decrease of the relative sales price and the sale-to-list ratio are the evidence of short period overreaction from the public, which decays over time. This study demonstrates an indirect method to estimate the perceived risk of the general public and provides valuable insight into sustainable port management policies.

Abstract
BACKGROUND Burn-blast combined injury is a kind of injury caused by heat and blast at the same time. The lung injury after burn-blast combined injuries is of primary importance, and investigation of lung injury is needed in the clinical care of patients. Computed tomography (CT) is one of the standard tools used to observe the anatomical basis and pathophysiology of acute lung injury. METHODS We applied a method of fast 3D (three-dimensional) reconstruction to calculate the density value of the lung injury by CT analysis. Blast-injury group (BL group), burn-injury group (B group), burn-blast combined injury group (BBL group), and sham control group (C group) were established. Each group had 16 rats. The three-dimensional images of the lung tissue were obtained at 6h, 24h, and 48h according to the CT value. The average density of the whole lung, left lung, and right lung were measured. The lung tissues were paraffin-embedded and HE stained. Smith scoring was performed according to the pathological findings. RESULTS In the BBL group, the density of the lung tissue was higher than those of the BL group and B group (P<0.01). The lung tissue density values at 24h after injury were higher than those at 6h and 48h after injury (P<0.01). Pathological results confirmed the changes of density analysis of the lung tissue. CONCLUSION The results have indicated that density analysis through a CT scan can be used as a way to evaluate lung injury in a burn-blast injury.

Abstract
OBJECTIVES Emergency medical system for mass casualty incidents (EMS-MCIs) is a global issue. However, China lacks such studies extremely, which cannot meet the requirement of rapid decision-support system. This study aims to realize modeling EMS-MCIs in Shanghai, to improve mass casualty incident (MCI) rescue efficiency in China, and to provide a possible method of making rapid rescue decisions during MCIs. METHODS This study established a system dynamics (SD) model of EMS-MCIs using the Vensim DSS program. Intervention scenarios were designed as adjusting scales of MCIs, allocation of ambulances, allocation of emergency medical staff, and efficiency of organization and command. RESULTS Mortality increased with the increasing scale of MCIs, medical rescue capability of hospitals was relatively good, but the efficiency of organization and command was poor, and the prehospital time was too long. Mortality declined significantly when increasing ambulances and improving the efficiency of organization and command; triage and on-site first-aid time were shortened if increasing the availability of emergency medical staff. The effect was the most evident when 2,000 people were involved in MCIs; however, the influence was very small under the scale of 5,000 people. CONCLUSION The keys to decrease the mortality of MCIs were shortening the prehospital time and improving the efficiency of organization and command. For small-scale MCIs, improving the utilization rate of health resources was important in decreasing the mortality. For large-scale MCIs, increasing the number of ambulances and emergency medical professionals was the core to decrease prehospital time and mortality. For super-large-scale MCIs, increasing health resources was the premise.
