Evaluation of Chemical, Biological, Radiological, Nuclear, Explosives (CBRNE) Knowledge Change and Skills Confidence Among Frontline-Line Providers During the Russia-Ukraine War.

OBJECTIVE: The aim of this study was to evaluate the change in knowledge and skill confidence after implementation of a chemical, biological, radiological, nuclear, and explosive (CBRNE) training course during the Russia-Ukraine War. METHODS: Pre/post-test study in the Ukrainian cities of Kyiv, Dnipro, Zaporizhzhia, and Odesa. Fifteen CBRNE courses were conducted over a 3-mo period, August to October 2022. Change in knowledge and skills confidence were evaluated with pre/post-course written exams and practical skill assessments that were observed during the training exercises. Changes were analyzed based on nonparametric Wilcoxon matched-pairs signed-rank testing. Pre/post self-efficacy surveys were analyzed with McNemar's test for paired data. Course evaluations were conducted with standardized questions which assessed instruction quality, teaching relevance, knowledge gained, and post-course skills confidence. RESULTS: A total of 523 participants registered and completed 1 of the 15 courses. Overall mean pre-course test score: 57.8% (SD 20.7%); mean post-course test score: 81.4% (SD 11.3%); participants with increasing test scores: 90.7%; mean difference in score (95% confidence interval) 23.6% (21.2%-25.9%), P < 0.0001. Pre/post self-efficacy surveys (4-point Likert scale) noted participants recognized signs and symptoms of a CBRNE incident, and necessary skills to manage CBRNE exposures, P < 0.0001. CONCLUSIONS: The implementation of this CBRNE course for front-line providers in Ukraine was successful. To our knowledge, it was the first implementation of a field course during the current Russian-Ukraine war. Future research should evaluate knowledge retention and impact of our innovative Train-the-Trainer model. Further iterations should emphasize expanding the quantity of training equipment and practical skill sessions.

Clinical sequencing of soft tissue and bone sarcomas delineates diverse genomic landscapes and potential therapeutic targets.

The genetic, biologic, and clinical heterogeneity of sarcomas poses a challenge for the identification of therapeutic targets, clinical research, and advancing patient care. Because there are > 100 sarcoma subtypes, in-depth genetic studies have focused on one or a few subtypes. Herein, we report a comparative genetic analysis of 2,138 sarcomas representing 45 pathological entities. This cohort is prospectively analyzed using targeted sequencing to characterize subtype-specific somatic alterations in targetable pathways, rates of whole genome doubling, mutational signatures, and subtype-agnostic genomic clusters. The most common alterations are in cell cycle control and TP53, receptor tyrosine kinases/PI3K/RAS, and epigenetic regulators. Subtype-specific associations include TERT amplification in intimal sarcoma and SWI/SNF alterations in uterine adenosarcoma. Tumor mutational burden, while low compared to other cancers, varies between and within subtypes. This resource will improve sarcoma models, motivate studies of subtype-specific alterations, and inform investigations of genetic factors and their correlations with treatment response.

Perspectives on the current state of Nigeria's emergency care system among participants of an emergency medicine symposium: a qualitative appraisal.

INTRODUCTION: Emergency care systems provide timely and relevant care to the acutely ill and injured. Published commentaries have characterised deficiencies in the Nigerian emergency care system and offered potential solutions but have not included the perspectives of the Nigerian public. A more inclusive approach that includes feedback from the public may help improve the Nigerian emergency care system through better understanding of the needs, values and expectations of the community. METHODS: Participants of an emergency medicine symposium participated in focus group discussions that were randomly divided into small groups led by two trained facilitators. These facilitators asked open-ended, semistructured questions to lead discussions in the English language. Participant responses were audio-recorded and transcribed verbatim into transcripts. Two independent investigators employed conventional content analysis to code the transcripts until thematic saturation was achieved. RESULTS: Three descriptive themes emerged characterising the current state of Nigeria's emergency care system as it relates to prehospital care delivery, hospital care delivery and health system governance: rudimentary, vulnerable and disconnected. At the prehospital level, concepts revolved around emergency recognition and response, ambulance and frontline providers, and cultural norms. At the hospital level, concepts centred around the health workforce, clinical competency, hospital capacity and the burden of financial hardship. At the health system level, concepts concentrated on healthcare access and healthcare financing. Opportunities for emergency care system improvement at each component level were identified and explored. CONCLUSIONS: The participants in this study identified shortcomings and opportunities to improve prehospital care, hospital care and health system governance. The results of this study may help healthcare professionals, policy makers and community leaders identify gaps in the emergency care system and offer solutions in harmony with the needs, values and expectations of the community. If successful, these community-informed interventions may serve as a model to improve emergency care systems throughout Africa.

Results from the implementation of the World Health Organization Basic Emergency Care Course in Lagos, Nigeria.

Background: The emergency care of time-sensitive injuries and illnesses is increasingly recognized as an essential component of effective health care systems. However, many low- and middle-income countries (LMICs) lack healthcare providers formally trained in the care of emergency conditions. The Disease Control Priorities 3 project estimates that effective emergency care systems could avert up to half of all premature deaths in LMICs. Nigeria, a lower-middle income country of nearly 200 million people in Sub-Saharan Africa, could save approximately 100,000 lives per year with an effective emergency care system. The World Health Organization developed the Basic Emergency Care (BEC) course to train frontline healthcare workers in the management of emergency conditions in low resource settings. In this study we describe our work implementing the BEC course Nigeria. Methods: This study was designed as a mixed methods research analysis comparing pre- and post- course examination results and surveys to evaluate participant knowledge acquisition and levels of confidence with management of various emergency conditions. Thirty-two participants were involved in the course which took place over four days at the Lagos University Teaching hospital. Quantitative data was analyzed using Stata 14.2 (College Station, TX). Paired data sets were analyzed using McNemar's chi-squared. Unpaired data sets were analyzed using a Wilcoxon signed-rank test. Results: Post-course test scores showed significant improvement (p-value <0.001) as compared to pre-course. The average pre-course test score was 73% and average post-course score was 86.5%. Pre- and post-course questionnaires demonstrated significantly increased confidence in managing emergency conditions and agreement with course objectives. Conclusions: The WHO Basic Emergency Care (BEC) course successfully increased the knowledge and confidence of frontline emergency care providers in Nigeria. The course was well received by participants. Future study should focus on BEC course scalability and long-term knowledge retention.

Sedation Patterns and Hyperosmolar Therapy in Emergency Departments were Associated with Blood Pressure Variability and Outcomes in Patients with Spontaneous Intracranial Hemorrhage.

BACKGROUND: Spontaneous intracranial hemorrhage (sICH) is associated with high mortality. Little information exists to guide initial resuscitation in the emergency department (ED) setting. However, blood pressure variability (BPV) and mechanical ventilation (MV) are known risk factors for poor outcome in sICH. OBJECTIVES: The objective was to examine the associations between BPV and MV in ED (EDMV) and between two ED interventions - post-MV sedation and hyperosmolar therapy for elevated intracranial pressure - and BPV in the ED and in-hospital mortality. METHODS: We retrospectively studied adults with sICH and external ventricular drainage who were transferred to a quaternary academic medical center from other hospitals between January 2011 and September 2015. We used multivariable linear and logistic regressions to measure associations between clinical factors, BPV, and outcomes. RESULTS: We analyzed ED records from 259 patients. There were 143 (55%) EDMV patients who had more severe clinical factors and significantly higher values of all BPV indices than NoEDMV patients. Two clinical factors and none of the severity scores (i.e., Hunt and Hess, World Federation of Neurological Surgeons Grades, ICH score) correlated with BPV. Hyperosmolarity therapy without fluid resuscitation positively correlated with all BPV indices, whereas propofol infusion plus a narcotic negatively correlated with one of them. Two BPV indices, i.e., successive variation of blood pressure (BPSV) and absolute difference in blood pressure between ED triage and departure (BPDepart - Triage), were significantly associated with increased mortality rate. CONCLUSION: Patients receiving MV had significantly higher BPV, perhaps related to disease severity. Good ED sedation, hyperosmolar therapy, and fluid resuscitation were associated with less BPV and lower likelihood of death.

Transportation Management Affecting Outcomes of Patients With Spontaneous Intracranial Hemorrhage.

OBJECTIVE: Patients with spontaneous intracranial hemorrhage (sICH) have poor outcomes, in part because of blood pressure variability (BPV). Patients with sICH causing elevated intracranial pressure (ICP) are frequently transferred to tertiary centers for neurosurgical interventions. We hypothesized that BPV and care intensity during transport would correlate with outcomes in patients with sICH and elevated ICP. METHODS: We analyzed charts from adult sICH patients who were transferred from emergency departments to a quaternary academic center from January 1, 2011, to September 30, 2015, and received external ventricular drainage. Outcomes were in-hospital mortality and the Glasgow Coma Scale on day 5 (HD5GCS). Multivariable and ordinal logistic regressions were used for associations between clinical factors and outcomes. RESULTS: We analyzed 154 patients, 103 (67%) had subarachnoid hemorrhage and 51 (33%) intraparenchymal hemorrhage; 38 (25%) died. BPV components were similar between survivors and nonsurvivors and not associated with mortality. Each additional intervention during transport was associated with a 5-fold increase in likelihood to achieve a higher HD5GCS (odds ratio = 5.4; 95% confidence interval, 1.7-16; P = .004). CONCLUSION: BPV during transport was not associated with mortality. However, high standard deviation in systolic blood pressure during transport was associated with lower HD5GCS in patients with intraparenchymal hemorrhage. Further studies are needed to confirm our observations.

Interventions affecting blood pressure variability and outcomes after intubating patients with spontaneous intracranial hemorrhage.

INTRODUCTION: Spontaneous intracranial hemorrhage (sICH) that increases intracranial pressure (ICP) is a life-threatening emergency often requiring intubation in Emergency Departments (ED). A previous study of intubated ED patients found that providing ≥5 interventions after initiating mechanical ventilation (pMVI) reduced mortality rate. We hypothesized that pMVIs would lower blood pressure variability (BPV) in patients with sICH and thus improve survival rates and neurologic outcomes. METHOD: We performed a retrospective study of adults, who were transferred to a quaternary medical center between 01/01/2011 and 09/30/2015 for sICH, received an extraventricular drain during hospitalization. They were identified by International Classification of Diseases, version 9 (430.XX, 431.XX), and procedure code 02.21. Outcomes were BPV indices, death, and being discharged home. RESULTS: We analyzed records from 147 intubated patients transferred from 40 EDs. Forty-one percent of patients received ≥5 pMVIs and was associated with lower median successive variation in systolic blood pressure (BPSV) (31,[IQR 18-45) compared with those receiving 4 or less pMVIs (38[IQR 16-70]], p = 0.040). Three pMVIs, appropriate tidal volume, sedative infusion, and capnography were significantly associated with lower BPV. In addition to clinical factors, BPSV (OR 26; 95% CI 1.2, >100) and chest radiography (OR 0.3; 95% CI 0.09, 0.9) were associated with mortality rate. Use of quantitative capnography (OR 8.3; 95%CI, 4.7, 8.8) was associated with increased likelihood of being discharged home. CONCLUSIONS: In addition to disease severity, individual pMVIs were significantly associated with BPV and patient outcomes. Emergency physicians should perform pMVIs more frequently to prevent BPV and improve patients' outcomes.

Health status and health needs of older refugees from Syria in Lebanon.

BACKGROUND: The flight of Syrian and Palestinian families into Lebanon from Syria included a number of older refugees. This study sought to characterize the physical and emotional conditions, dietary habits, coping practices, and living conditions of this elderly population arriving in Lebanon between March 2011 and March 2013. METHODS: A systematic selection of 210 older refugees from Syria was drawn from a listing of 1800 refugees over age 60 receiving assistance from the Caritas Lebanon Migrant Center (CLMC) or the Palestinian Women's Humanitarian Organization (PALWHO). CLMC and PALWHO social workers collected qualitative and quantitative information during 2013. RESULTS: Two-thirds of older refugees described their health status as poor or very poor. Most reported at least one non-communicable disease, with 60% having hypertension, 47% reporting diabetes, and 30% indicating some form of heart disease. Difficulties in affording medicines were reported by 87%. Physicial limitations were common: 47% reported difficulty walking and 24% reported vision loss. About 10% were physically unable to leave their homes and 4% were bedridden. Most required medical aids such as walking canes and eyeglasses. Diet was inadequate with older refugees reporting regularly reducing portion sizes, skipping meals, and limiting intake of fruits, vegetables, and meats. Often this was done to provide more food to younger family members. Some 61% of refugees reported feeling anxious, and significant proportions of older persons reported feelings of depression, loneliness, and believing they were a burden to their families. 74% of older refugees indicated varying degrees of dependency on humanitarian assistance. CONCLUSION: The study concluded older refugees from Syria are a highly vulnerable population needing health surveillance and targeted assistance. Programs assisting vulnerable populations may concentrate services on women and children leaving the elderly overlooked.
