COVID-19: a review on SARS-CoV-2 origin, epidemiology, virology, clinical manifestations and complications with special emphasis on adverse outcome in Bhopal Gas Tragedy survivor.

After the global outbreak of coronaviruses caused diseases such as Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS), an outbreak due to these viruses occurred in December, 2019 in Wuhan, Hubei Province, China and led to a worldwide spread. Coronavirus 2019 disease (COVID-19) has emerged as a serious global health emergency and spread from a person to another who has the virus. But the scope of an intermediate host is not known. Population at higher risk includes individuals in higher age group (>60 years) or with comorbidities such as diabetes, hypertension, cardiovascular disease and weaker immune system. Many unknown and underestimate risk factors could be responsible for adverse outcomes in COVID-19. These risk factors should be appropriately identified, addressed and necessary actions should be taken to mitigate the effect of COVID-19 pandemic. Bhopal gas tragedy was one of the world's worst industrial chemical leak disaster. The survivors of this incident still suffer from the various complications such as increased rate of cancers, chronic illness like tuberculosis, respiratory diseases, birth defects, nerve injury, growth retardations, gynecological illness and many more. The survivors of Bhopal gas tragedy are at higher risk of developing COVID-19 related adverse outcome. One of the possible explanations can be long term effect of methyl isocyanate (MIC). MIC exposure can lead to possible toxic effect on genetic, epigenetic and non-genetic factors. In this review, we aim to establish the scientific basis for adverse outcome in COVID-19 patients who are also victims of Bhopal gas tragedy.

Influence of post-disaster evacuation on incidence of hyperuricemia in residents of Fukushima Prefecture: the Fukushima Health Management Survey.

AIM: After the Great East Japan Earthquake, over 160,000 residents in Fukushima Prefecture were forced to evacuate the area around the Fukushima Daiichi power plant following nuclear accident there. Health problems in these evacuees have since become a major issue. We have examined the association between evacuation and incidence of hyperuricemia among residents in Fukushima. METHODS: We conducted a cohort study of residents aged 40-90 years without hyperuricemia at the time of the Fukushima disaster. Among 8173 residents who met the inclusion criteria before the disaster, 4789 residents (men: 1971, women: 2818; follow-up duration: 1.38 years; and follow-up rate: 58.6%) remained available for follow-up examinations at the end of March 2013. The main endpoint was incidence of hyperuricemia, defined by the Japanese committee guidelines, using local health data from before and after the disaster. We divided participants by evacuation status and compared outcomes between groups. Using a logistic regression model, we estimated the odds ratio for incidence of hyperuricemia, adjusting for potential confounders, age, gender, waist circumference, physical activity, and alcohol consumption. RESULTS: Incidence of hyperuricemia was higher in evacuees (men 10.1%; women 1.1%) than in non-evacuees (men 7.4%, women 1.0%). Evacuees had higher body mass index, waist circumference, triglycerides, LDL-cholesterol, fasting plasma glucose, HbA1c, and lower HDL-cholesterol after the disaster than non-evacuees. We found that evacuation was associated with incidence of hyperuricemia (adjusted odds ratio: 1.38; 95% confidence interval: 1.03-1.86). CONCLUSION: This is the first study to demonstrate an association between evacuation after a disaster and increased incidence of hyperuricemia.

Changes in smoking behavior among victims after the great East Japan earthquake and tsunami.

BACKGROUND: In areas affected by the tsunami of the great East Japan Earthquake, smoking behavior may have deteriorated due to high stress and drastic changes in living environment. Surveys were conducted to reveal changes in smoking behaviors among victims. METHODS: A population-based random-sample home-visit interview survey of victims in Iwate and Miyagi Prefectures affected by the tsunami disaster was conducted in 2012 (n = 1978), while a population-based nationwide survey was conducted in 2013 (n = 1082). A panel survey in 2014 was conducted with respondents of the 2012 survey (n = 930). Multiple logistic regression analysis was performed to reveal factors related to smoking status after the disaster. RESULTS: There was high smoking prevalence of both sexes in the tsunami disaster area (current smoking rate in coastal area, 50.0% for male, 21.4% for female; inland area, 34.7% for male, 7.6% for female). Low prevalence of male quitters was observed (quitter rate in coastal area, 20.8% for male, 8.0% for female; inland area, 23.4% for male, 5.5% for female). The prevalence of nicotine-dependent people assessed by FTND (Fagerström Test for Nicotine Dependence) in the coastal area was also higher than in the inland area or other areas of Japan. Smoking behavior among victims worsened after the disaster and did not improve 3 years from the disaster. Post-disaster factors related to smoking were living in coastal area, complete destruction of house, and living in temporary housing. CONCLUSIONS: Smoking prevalence and the level of nicotine dependence of tsunami victims were still high even 3 years after the disaster. It is important to emphasize measures for smoking control in the disaster areas for an extended time period.

Design and Progress of Oral Health Examinations in the Tohoku Medical Megabank Project.

In order to assess the long-term impact of the Great East Japan Earthquake on the oral health of disaster victims and to evaluate gene-environmental interactions in the development of major oral diseases and oral-systemic associations, the oral part of two large-scale genome cohort studies by the Tohoku Medical Megabank Organization (ToMMo), including the Community-based cohort (CommCohort) study and the Birth and Three-Generation cohort (BirThree) study, have been conducted. The study population comprised 32,185 subjects, including 16,886 participants in the CommCohort study and 15,299 participants in the BirThree cohort study, recruited from 2013 to 2017. The oral studies consist of a questionnaire regarding oral hygiene behavior, clinical examinations by dentists, and oral plaque and saliva sampling for microbiome analyses, which were carried out at seven community support centers in Miyagi prefecture. The median age of all participants was 55.0 years, and 66.1% of participants were women. Almost all participants reported that they brushed their teeth more than once a day. The median number of present teeth was 27.0, and the decayed, missing and filled tooth number was 16.0, with a significant difference according to age and sex. The median periodontal pocket and clinical attachment level was 2.48 mm and 4.00 mm, respectively. Periodontal parameters increased significantly according to age, except for the accumulation of dental calculus. The oral part of these extensive cross-sectional studies provides a unique and important platform for future studies on oral health and diseases that elicit through interactions with systemic diseases, lifestyles, life events and genetic backgrounds, and contributes to researches clarifying the long-term effects of disasters on oral health.

Tropical cyclone Fani-perspective from the trauma and emergency department of an affected tertiary hospital.

PURPOSE: To explore the epidemiological and clinical profile of patients admitted to the trauma and emergency department (TED) of a tertiary care hospital due to tropical cyclone Fani and highlight the challenges faced by the hospital in this natural disaster. METHODS: A retrospective study was conducted in the TED in the affected zone. Data of all victims affected by the cyclone Fani on May 3, 2019 were obtained from disaster records and medical case sheets. All patients except death on admission were included. Clinical variables included anatomical sites and severity of injuries which was assessed by revised trauma score (RTS) and injury severity score (ISS). Trauma injury severity score (TRISS) was also calculated. RESULTS: Of 75 patients, 74 were included and the other one was brought dead and thus excluded. The age, median ± interquartile range (IQ), was 41.0 (27.7-53.0) years. The male to female ratio was 2:1. Most of the wounded were transported by the police control room vans on day 1: first 10 h, 50.0%; 10-24 h, 20.3%. The median ± IQ range of RTS, ISS and TRISS were 20 (14-28), 7.84 (7.841-7.841), and 97.4 (91.6-98.9), respectively. Simple external injury was the dominant injury type. Polytrauma (ISS >15) was seen in 67% cases and spine injury in 14% cases (7% cervical and 7% thoracolumbar). Injury causes included sharp flying objects (broken pieces of glasses and asbestos) in 31% cases, followed by fall of trees in 20.3%. Twenty-four patients were discharged after primary treatment, 30 admitted to the indoor-trauma ward or intensive care unit and 20 deferred or transferred to another center. There was no in-house mortality. Challenges were related to electricity failure, mobile network breakdown, infrastructure collapse, and delay in expertise repair from outside due to airport/railway closure. CONCLUSION: In cyclonic storm like Fani, sharp flying objects, fall of trees/poles and collapsing walls constitute the common mode of injuries causing harm to more than one body regions. Polytrauma was seen in the majority of patients though external injury was the commonest. The affected hospital had the uphill task of treating hospitalized patients as well as disaster victims.

Long-term displacement associated with health and stress among survivors of Typhoon Haiyan.

Displacement from one's home after a natural disaster results not only in physical separation from significant others but also in profound disruptions of psychological and social resources such as community support and sense of belonging. Frequent displacement can exacerbate health and mental health problems brought by the disaster, especially among lower-income families in resource-scarce regions. OBJECTIVE: The present study examined the association among frequency of displacement after the disaster, health status, and psychological adjustments among survivors four years after the 2013 Super Typhoon Haiyan in the Philippines. METHOD: The study surveyed 345 typhoon survivors using randomized cluster samples in 13 towns in Eastern Philippines and assessed their physical and mental health status. RESULT: Path analysis revealed that, after controlling for age, gender, and traumatic exposure severity, frequency of displacement was a significant predictor for subjective health ratings and stress but not for posttraumatic stress symptoms, depression, and anxiety. CONCLUSION: These findings underscore the detrimental impact of long-term displacement on health outcomes following a disaster, especially in countries where public health resources are largely unavailable.

Daily Bicycle and Pedestrian Activity as an Indicator of Disaster Recovery: A Hurricane Harvey Case Study.

Changes in levels and patterns of physical activity might be a mechanism to assess and inform disaster recovery through the lens of wellbeing. However, few studies have examined disaster impacts on physical activity or the potential for physical activity to serve as an indicator of disaster recovery. In this exploratory study, we examined daily bicycle and pedestrian counts from four public bicycle/pedestrian trails in Houston, before and after Hurricane Harvey landfall, to assess if physical activity returned to pre-Harvey levels. An interrupted time series analysis was conducted to examine the immediate impact of Harvey landfall on physical activity; t-tests were performed to assess if trail usage returned to pre-Harvey levels. Hurricane Harvey was found to have a significant negative impact on daily pedestrian and bicycle counts for three of the four trails. Daily pedestrian and bicycle counts were found to return to pre-Harvey or higher levels at 6 weeks post-landfall at all locations studied. We discuss the potential for further research to examine the trends, feasibility, validity, and limitations of using bicycle and pedestrian use levels as a proxy for disaster recovery and wellbeing among affected populations.

Clinical and demographic profile of admitted victims in a tertiary hospital after the 2015 earthquake in Nepal.

BACKGROUND: In 2015, an earthquake killing 9,000 and injuring 22,000 people hit Nepal. The Tribhuvan University Teaching Hospital (TUTH), a reference tertiary hospital, was operational immediately after the earthquake. We studied the profile of earthquake victims admitted in TUTH and assessed what factors could influence hospital length of stay. METHODS: An earthquake victim dataset was created based on patient records, with information on sex, age, date of admission and discharge, diagnosis, and surgical intervention. We performed an initial descriptive overview of the earthquake victims followed by a time-to-event analysis to compare length of hospital stay in different groups, using log rank test and cox regression to calculate Hazard Ratios. RESULTS: There were in total 501 admitted victims, with the peak of admissions occurring on the fifth day after the earthquake. About 89% had injury as main diagnosis, mostly in lower limbs, and 66% of all injuries were fractures. Nearly 69% of all patients underwent surgery. The median length of hospital stay was 10 days. Lower limb and trunk injuries had longer hospital stays than injuries in the head and neck (HR = 0.68, p = 0.009, and HR = 0.62 p = 0.005, respectively). Plastic surgeries had longer hospital stays than orthopaedic surgeries (HR = 0.57 p = 0.006). Having a crush injury and undergoing an amputation also increased time to discharge (HR = 0.57, p = 0.013, and HR = 0.65 p = 0.045 respectively). CONCLUSIONS: Hospital stay was particularly long in this sample in comparison to other studies on earthquake victims, indirectly indicating the high burden TUTH had to bear to treat these patients. To strengthen resilience, tertiary hospitals should have preparedness plans to cope with a large influx of injured patients after a large-scale disaster, in particular for the initial days when there is limited external aid.

Disaster-Related Surveillance Among US Virgin Islands (USVI) Shelters During the Hurricanes Irma and Maria Response.

OBJECTIVES: Two Category 5 storms, Hurricane Irma and Hurricane Maria, hit the U.S. Virgin Islands (USVI) within 13 days of each other in September 2017. These storms caused catastrophic damage across the territory, including widespread loss of power, destruction of homes, and devastation of critical infrastructure. During large scale disasters such as Hurricanes Irma and Maria, public health surveillance is an important tool to track emerging illnesses and injuries, identify at-risk populations, and assess the effectiveness of response efforts. The USVI Department of Health (DoH) partnered with shelter staff volunteers to monitor the health of the sheltered population and help guide response efforts. METHODS: Shelter volunteers collect data on the American Red Cross Aggregate Morbidity Report form that tallies the number of client visits at a shelter's health services every 24 hours. Morbidity data were collected at all 5 shelters on St. Thomas and St. Croix between September and October 2017. This article describes the health surveillance data collected in response to Hurricanes Irma and Maria. RESULTS: Following Hurricanes Irma and Maria, 1130 health-related client visits were reported, accounting for 1655 reasons for the visits (each client may have more than 1 reason for a single visit). Only 1 shelter reported data daily. Over half of visits (51.2%) were for health care management; 17.7% for acute illnesses, which include respiratory conditions, gastrointestinal symptoms, and pain; 14.6% for exacerbation of chronic disease; 9.8% for mental health; and 6.7% for injury. Shelter volunteers treated many clients within the shelters; however, reporting of the disposition (eg, referred to physician, pharmacist) was often missed (78.1%). CONCLUSION: Shelter surveillance is an efficient means of quickly identifying and characterizing health issues and concerns in sheltered populations following disasters, allowing for the development of evidence-based strategies to address identified needs. When incorporated into broader surveillance strategies using multiple data sources, shelter data can enable disaster epidemiologists to paint a more comprehensive picture of community health, thereby planning and responding to health issues both within and outside of shelters. The findings from this report illustrated that managing chronic conditions presented a more notable resource demand than acute injuries and illnesses. Although there remains room for improvement because reporting was inconsistent throughout the response, the capacity of shelter staff to address the health needs of shelter residents and the ability to monitor the health needs in the sheltered population were critical resources for the USVI DoH overwhelmed by the disaster.

A Simultaneous Cluster Analysis of Cognitive, Emotional, and Personality Factors and Insomnia and Sleep Quality Among Earthquake Victims.

OBJECTIVE: The current study compares the measures of sleep quality and intensity of insomnia based on the clustering analysis of variables including dysfunctional beliefs and attitudes about sleep, experiential avoidance, personality traits of neuroticism, and complications with emotion regulation among the individuals struck by an earthquake in Kermanshah Province. METHODS: This study is a cross-sectional study that was carried out among earthquake victims of Kermanshah Province (western Iran) in 2017. Data were gathered starting 10 days after the earthquake and lasted for 2 weeks; of 1,200 standard questionnaires distributed, 1,001 responses were received, and the analysis was performed using 999 participants. The data analysis was carried out using a cluster analysis (K-mean method). RESULTS: Two clusters were identified, and there is a significant difference between these two clusters in regard to all of the variables. The cluster with higher mean values for the selected variables shows a higher intensity of insomnia and a lower sleep quality. CONCLUSIONS: Considering the current results, it can be concluded that variables of dysfunctional attitudes and beliefs about sleep, experiential avoidance, the personality traits of neuroticism, and complications with emotion regulation are able to identify the clusters where there is a significant difference in regard to sleep quality and the intensity of insomnia.

Cumulative Disaster Exposure and Mental and Physical Health Symptoms Among a Large Sample of Gulf Coast Residents.

A large body of research has linked disaster exposure to adverse mental and physical health outcomes. Few studies, however, have explored the cumulative impact of exposure to multiple disasters. Participants (N = 8,366) from the National Institute of Environmental Health Sciences Gulf Long-Term Follow-Up Study were classified as having been exposed to both, either, or neither Hurricane Katrina and the Deepwater Horizon oil spill (DHOS). Participants also reported on a range of mental and physical health symptoms. Logistic regression models found that participants who were exposed to both disasters had significantly higher odds of probable generalized anxiety disorder, odds ratio (OR) = 1.72, 95% CI [1.52, 1.96]; major depression, OR = 1.53, 95% CI [1.32, 1.77]; and posttraumatic stress disorder, OR = 2.51, 95% CI [2.03, 3.10], than participants who were exposed to only one disaster, ps < .001. Additionally, a linear regression model found that participants who were exposed to both disasters had significantly more physical health symptoms at the time of the spill than those who were exposed to only one disaster, B = 0.99, SE = .20, p < .001. The results indicate that cumulative disaster exposure confers enhanced risk for adverse mental and physical health outcomes. The findings demonstrate that screening for prior exposure among disaster-affected individuals might identify those at greatest risk for adverse health outcomes.

Spanish Abstracts by Asociación Chilena de Estrés Traumático (ACET) Exposición Acumulativa a Desastres y Síntomas de Salud Mentales y Físicos entre una Amplia Muestra de Residentes del Golfo de México EXPOSICION ACUMULATIVA AL DESASTRE Y SINTOMAS DE SALUD Un vasta serie de investigaciones ha vinculado la exposición a desastres con resultados adversos en la salud mental y física. Sin embargo, escasos estudios han explorado el impacto acumulativo de la exposición a múltiples desastres Los participantes (N = 8,366) del Estudio de Seguimiento a Largo Plazo del Golfo del Instituto Nacional de Ciencias de la Salud Ambiental fueron clasificados como expuesto a ambos, ya sea al Huracán Katrina o al derrame de petróleo de Deepwater Horizon (DHOS en sus siglas en inglés). Los participantes también informaron un rango de síntomas de salud mental y física. Modelos de regresión logística encontraron que los participantes que estuvieron expuestos a ambos desastres tuvieron probabilidades significativamente más altas de presentar trastorno de ansiedad generalizada, proporción de probabilidades (OR) = 1.72, IC 95% [1.52, 1.96]; depresión mayor, OR = 1,53, IC del 95% [1,32, 1,77]; y trastorno de estrés postraumático, OR = 2.51, IC 95% [2.03, 3.10], comparado con los participantes que estuvieron expuestos a un sólo desastre, ps<.001. Adicionalmente, un modelo de regresión lineal encontró que los participantes que fueron expuestos a ambos desastres tuvieron significativamente más síntomas de salud física en el momento del derrame que aquellos que estuvieron expuestos a un sólo desastre, B = 0.99, SE = .20, p <.001. Los resultados indican que la exposición acumulativa al desastre confiere mayor riesgo de resultados adversos para la salud mental y física. Los hallazgos demuestran que la detección de la exposición previa entre individuos afectados por un desastre podría identificar aquellos con mayor riesgo para presentar resultados adversos para la salud.

The Imbalance in Medical Demand and Supply for Pediatric Victims in an Earthquake.

OBJECTIVES: We quantified an absolute imbalance of the medical risks and the support needs for children at each disaster-based hospital in Kanagawa immediately following the occurrence of a large earthquake by using the risk resource ratio (RRR) and need for medical resources (NMR). METHODS: The RRR and NMR of 33 disaster-based hospitals were estimated through dividing the estimated number of pediatric victims by the number of critically patients. We calculated the ratio of the NMR of each hospital. RESULTS: The total number of pediatric victims in Kanagawa was estimated at 8,391. The total number of vacant beds for pediatric victims was 352. The median RRR and NMR of the total number of pediatric victims were 27 and 224. The median RRR and NMR of the number of critically ill pediatric patients were 27 and 12. CONCLUSIONS: The absolute imbalance of the RRR and NMR for children in Kanagawa was quantified. This suggests that we might embark on preparedness strategies for children in advance.

The preliminary investigation of orexigenic hormone gene polymorphisms on posttraumatic stress disorder symptoms.

Orexigenic hormones are a group of hormones that can up-regulate appetite. Current studies have shown that orexigenic hormones also play important roles in stress responses and may be implicated in regulation of fear memory. However, these conclusions lack evidence from human studies. In this study, we examined associations between orexigenic hormone genes and fear-related mental disorders by investigating main, G × E, and G × G effects of ghrelin and orexin gene single nucleotide polymorphisms (SNPs) on human posttraumatic stress disorder (PTSD) symptoms in 1134 Chinese earthquake survivors. SNPs Leu72Met of the GHRL gene (rs696217), Ile408Val of the HCRTR1 gene (rs2271933) and Val308Ile of the HCRTR2 gene (rs2653349) were genotyped. None of the SNPs showed significant main or G × E effects. However, a significant interaction effect between GHRL rs696217 and HCRTR1 rs2271933 was found to predict the PTSD Checklist (PCL-5) total score (P = 0.007). Further analysis revealed different interaction patterns in males and females. For females, the rs2271933 G allele was associated with an increased PCL-5 total score (B = 2.59, P = 0.024) when the rs696217 genotype TT/TG was present. For males, the rs696217 T allele is associated with an increased PCL-5 total score (B = 3.62, P = 0.040) when the rs2271933 genotype GG/GA was present. These current findings expand our knowledge of physiological function of the orexigenic hormone system, and suggest its involvement in development of fear-related mental disorders such as PTSD.

The Knowledge Level of Dentists in Turkey About Their Potential Role on the Disaster Victims Identification (DVI) Team.

OBJECTIVE: Although dentists are valuable assets in identification teams during disaster events, forensic dentistry is not used effectively in the identification studies conducted in Turkey, and the importance of dental data is ignored. The aim of this study was to determine the level of knowledge of dentists regarding their duties and responsibilities during major disasters. METHODS: This descriptive study was conducted between December 2015 and June 2016. Registered dentists (n=20.280) of the Turkish Dental Association were invited to complete the organization's online survey. A total of 539 dentists participated in the volunteer workshop. Data were analyzed using SPSS, version 22.0 (IBM Corp, Armonk, NY). The chi-square analysis was used to evaluate the knowledge level of dentists by group regarding disaster victim identification (DVI) - the process and procedure of recovering and identifying victims of major disasters (eg, earthquake, terrorist attack). RESULTS: The dentists included in the study consisted of 320 (59.4%) females and 219 (40.6%) males with a mean age of 37.4±12.6 years. The number of specialists and general dentists were 249 (45.6%) and 297 (54.4%), respectively; 249 (69.71%) dentists who had knowledge about forensic dentistry stated that they received this information during their formal training. The percentage of dentists who were aware of the existence of an organization of a disaster response operation in Turkey was 74.2%, but only 20.5% (n=110) had knowledge about DVI. We found that 92.9% (n=104) of these dentists believed that dentists should be included in the team for the identification of disaster victims. On the other hand, only half (52.3%) of the dentists with knowledge of DVI wanted to work on the identification teams. The majority (99.1%) considered DNA analysis to be the safest method for identification. CONCLUSION: Our findings show that, although dentists know about the identification process, they do not have enough relevant knowledge. (Disaster Med Public Health Preparedness. 2019;13:533-538).

Genomic mapping of ST85 blaNDM-1 and blaOXA-94 producing Acinetobacter baumannii isolates from Syrian Civil War Victims.

OBJECTIVES: The rapid emergence of carbapenem-resistant Acinetobacter baumannii is a global health concern. A comparative genomic analysis was performed on two ST85 A. baumannii strains harboring blaNDM-1 and blaOXA-94 collected in Lebanon from Syrian Civil War victims. METHODS: Genome sequencing data of ACMH-6200 and ACMH-6201 were used for in silico extraction of multilocus sequence types (MLST), resistance genes, and virulence factors. Plasmids were genetically mapped in silico and using PCR-based replicon typing (PBRT). The genetic environment of blaNDM-1 and blaOXA-94 was determined, and whole-genome single nucleotide polymorphism (wgSNP) analysis in comparison with 41 publicly available A. baumannii genomes was performed. RESULTS: Tn125 carrying blaNDM-1 was truncated by the insertion of ISAba14 downstream of dct, generating ΔTn125. blaOXA-94 was upstream of ISAba13 and ISAba17. Resistance to ceftazidime could be attributed to AmpC cephalosporinase encoded by blaADC-25, and to blaNDM-1 on plasmids. GyrA (S83L) and ParC (S80L) substitutions conferred resistance to fluoroquinolones. wgSNP analysis separated the isolates based on their sequence types. CONCLUSIONS: The role of refugees in the transmission of antimicrobial resistance in developing countries is understudied. As such, this study sheds light on the correlation between population mobility and the importation of drug-resistant pathogens. It also highlights the manifold mechanisms underlying antibiotic resistance in A. baumannii.

Managing the "Worried Well" during a large-scale incident.

A number of recent incidents in the United States resulted in a large number of citizens reporting to the Emergency Room seeking reassurance that they were okay. These citizens are being referred to in the medical community as the "Worried Well." We conducted a review of a transportation incident involving a chemical release and fire, which resulted in over 100 people reporting to the local emergency room for evaluation. Few, if any of the patients seen in the hospital had a potential exposure to the chemical or combustion byproducts. It is probable that stress hormones released by the sympathetic nervous system caused the symptoms experienced by the majority of the patients. This review suggest the need for better coordination between incident command and the hospital, including more timely situation reports including parameters such as the wind direction and potential downwind pollutant levels, to assist the physicians and nurses more appropriately manage these "Worried Well."

Disaster Mental Health Services Review of Care for Older Persons After Disasters.

As older persons make up an ever greater proportion of the world's population, a range of concerns are being voiced by policy-makers, program managers, and care providers about best or optimal practices for serving this population's needs during all stages of disasters. Given that age-related vulnerabilities are common in late life, this article describes existing systems of care in the United States for the provision of disaster mental health services. Second, it evaluates the evidence for disaster treatment interventions with this subgroup of the population. Third, it synthesizes the findings of recent studies focusing on screening, assessment, and treatment approaches. To advance our current system of care and to adequately respond to the mental health needs of older persons, it is advantageous to periodically review progress, identify current gaps and unmet needs, and describe opportunities for improvement. (Disaster Med Public Health Preparedness. 2018; 12: 366-372).
