Background: Asthma is a common chronic respiratory inflammatory disease that adversely affects patients' quality of life (QoL) and overall well-being. When asthma is not adequately controlled, there is a higher risk of exacerbations and hospitalizations, thereby increasing the direct and indirect costs associated with the treatment and productivity loss. Overreliance on SABA and underutilization of ICS in the management of asthma can result in suboptimal treatment and poor asthma control. Patients who visit the emergency department are more likely to have poorly controlled asthma. Ensuring that these patients are provided with an evidence-based treatment plan during discharge can help reduce the risk of future exacerbations and consequently reduce the burden on the UAE healthcare system.

Methods: A joint task force comprising experts from the Emirates Society of Emergency Medicine (ESEM) and Emirates Thoracic Society (ETS) reviewed published evidence and updated guidelines in asthma management to optimize the post-discharge recommendations.

Results: The ESEM-ETS experts' joint task force has developed a step-by-step plan for emergency department/hospital discharge, which is based on the GINA 2023 guideline recommendations and the medications available in the UAE. By adhering to this structured plan, emergency department physicians can play a crucial role in improving asthma care, long-term patient outcomes, and the utilization of healthcare resources.

Conclusions: Prioritizing patient education and ensuring patients are equipped with the best-suited asthma treatment plans prior to discharge can help ED physicians improve patient outcomes and reduce healthcare resource utilization in UAE hospitals.

Background: The introduction of Emergency Medicine in Rwanda in 2015 has been associated with a mortality reduction in patients presenting to Kigali University Teaching Hospital (KUTH). In the context of increasing numbers of critically ill patients presenting to Emergency Departments (ED) globally, the aim of this study was to describe the characteristics of critically ill patients, the critical care interventions performed, and the outcomes of critically ill patients presenting to the KUTH ED with the goal of informing future research into the root causes of mortality of critically ill ED patients and of identifying high yield topics for didactic and procedural training.

Methods: A descriptive observational prospective cohort pilot study analyzed all patients ≥15 years who presented to KUTH between April and June 2022 with modified South African Triage Scores of Red with alarm, Red without alarm, and Orange.

Results: Of 320 patients, 66.9% were male and median age was 40 years. Patients were triaged as Orange (65.3%), Red without alarm (22.8%), and Red with alarm (11.9%). Presentations were categorized as: medical emergencies (48.0%), traumatic injury (44.5%), and surgical emergencies (7.6%). Median length of stay was 31 h (IQR 28, 56) and boarding was 23 h (IQR 8, 48). Overall mortality was 12.2% and highest among medical emergencies (16.5%, p = 0.048) and increased significantly with triage color: Red with alarm (47.4%), Red without alarm (16.4%), and Orange (4.3%, p < 0.0001). Cardiopulmonary resuscitation (CPR) (10.3%), endotracheal intubation (8.8%), and vasopressor administration (3.1%) were the most frequent critical interventions performed. Survival after cardiac arrest was 9.1% and 32.1% after intubation. Mortality was associated with the following interventions: CPR, intubation, and use of vasopressors (p < 0.05).

Conclusions: This pilot study identified the most common critical care interventions performed and a high mortality among patients who required these interventions in the ED of a tertiary teaching hospital in Rwanda. These findings will inform didactics and procedural training for emergency care providers. Future research should focus on the root causes of mortality in these specific patient populations and identify areas of system strengthening to reduce mortality.

Objective: This study aimed to identify predictors of brain CT abnormalities in patients who sustained a mild traumatic brain injury (mTBI).

Methods: Retrospective observational cohort of adult patients with mTBI (Glasgow Coma Score 13-15) that occurred within the preceding 24 h.

Results: 2548 (91%) of the cohort had a brain CT and 698 (27%) demonstrated abnormal findings. The most frequently observed CT abnormalities were bleeding (638, 25%) and fractures (190, 7.4%). Multivariate logistic regression analysis revealed several significant predictors associated with the presence of brain CT abnormalities including older age [P < 0.0001], male sex [P < 0.0001], loss of consciousness [P = 0.0041], associated vomiting [P = 0.0011], alteration of consciousness (AOC) [P = 0102], and GCS score [P < 0.0001]. This was a robust model with an R² of 14.2%.

Conclusion: In this retrospective analysis, older age, male sex, the presence of loss of consciousness or alteration in consciousness, lower GCS score, and associated vomiting were found to be significant predictors of having an abnormal brain CT. These findings highlight the importance of considering these factors when determining the necessity of brain CT scans in patients with mTBI and suggest that existing clinical decision rules may be limited. These findings may also help to inform clinical decision rules. Early identification of individuals at a higher risk of CT abnormalities may assist in appropriate management and allocation of healthcare resources.

Background: The recreational use of nitrous oxide is becoming increasingly common among teenagers and young adults. Since 2018, the use of nitrous oxide has increased exponentially and has become a public health problem.

Case presentation: A 23-year-old patient was referred to accident and emergency (A&E) by his general practitioner for deterioration in general condition, vomiting, diarrhea and febrile headache at 39 °C. He reported that he had been partying for a month and consuming alcohol, cannabis and nitrous oxide. Three days before the consultation, he reported increased abdominal pain in the right iliac fossa. His homocysteine concentration was 51.9 μmol/L, and his plasma methyl malonate concentration increased to 4.45 μmol/L. A thoracic and abdominal CT scan revealed right iliac venous thrombosis associated with bilateral pulmonary embolism.

Conclusion: Nitrous oxide inhibits the activity of methionine synthetase. We therefore observed an increase in plasma homocysteine and 5-methyl-THF. The increase in homocysteine could be responsible for the pro-thrombotic activity resulting from nitrous oxide intoxication. At present, no threshold or duration of exposure has been identified as being particularly likely to cause complications. It is likely that other factors coexist, such as coagulation disorders and polymorphisms of the MHTFR gene, which can lead to hyperhomocysteinaemia, cannabis consumption, inflammatory conditions and others. Treatment is based on vitamin B12 supplementation and curative anticoagulation. Some authors also recommend folate supplementation. Consumption of nitrous oxide could be associated with arterial and venous thromboembolic disease.

Introduction: In recent years, tenecteplase has been competing with alteplase as a treatment for acute ischemic stroke given its ease of administration, lower dosage, cost-effectiveness, and better safety data. This paper seeks to analyze academic literature regarding the burgeoning usage of tenecteplase as a treatment for acute ischemic stroke across the world.

Method: The Web of Science database was used to collect the data from articles containing the keywords "Tenecteplase" and "Stroke" published from 1999 to 2023. The search resulted in 576 journal articles. This study analyzed metadata related to the country, institution, keywords, and date published for each article in the database pertaining to tenecteplase use for stroke.

Results: The United States led in publications (260, 39.93%), followed by Australia (101, 15.51%), and a tie for third place between Canada and China (77, 11.83% each). The three most prevalent keywords were tenecteplase (N = 324), alteplase (N = 284), and thrombolysis (N = 244). The University of Melbourne and the University of Calgary were the leading institutions publishing on the use of tenecteplase as a treatment for stroke. In 2023, the number of publications on the usage of tenecteplase for stroke was the greatest, making up 24.3% of all papers on the topic.

Conclusion: The surge in academic papers regarding tenecteplase in stroke in 2023 could be a good indicator of the drug's increasing prevalence as a treatment for stroke. Despite this finding, tenecteplase is currently not an FDA-approved therapy in the US as Genentech, the drug's manufacturer, has yet to file for federal approval for acute ischemic stroke treatment.

Background: Mild traumatic brain injury (mTBI) is becoming a more common emergency department (ED) presentation. Towards this end, many types of testing in the acute setting are being investigated. One of these is screening for convergence insufficiency (CI) symptoms. These are common problems reported by patients with mTBI, but such oculomotor testing is rarely performed in the ED.

Objective: To assess the feasibility of convergence insufficiency screening in the ED and investigate whether CI is associated with adverse events such as post-concussive symptoms or hospital admission.

Methods: Written informed consent was obtained from patients age 18 years or older who experienced a mild head injury from any mechanism resulting in an mTBI. Patients underwent screening for CI symptoms using a standardized instrument of 15 questions, known as the convergence insufficiency symptom survey (CISS), with responses based on the Likert scale. These data were correlated to outcomes of hospital admission, occurrence of post-concussive symptoms, and 30-day hospital re-admission.

Results: A total of 116 patients were prospectively enrolled, of which 58 were male. The median age was 31 years, with a range of 18 to 95 years of age. The median CISS score was 13, with an interquartile range (IQR) of 6 to 21 and an overall range of 0 to 53. Females presented with a median CISS score of 14, which was higher compared to the male median score of 10. The higher the CISS score, the more likely the patient was to be admitted to the hospital (p = 0.0378), develop symptoms of post-concussive syndrome at 30-day follow up (p = 0.0322), and be readmitted within 30 days (p = 0.0098).

Conclusions: Screening for CI symptoms using the CISS can be a solid adjunct in the evaluation of mTBI in the ED. The CISS is easy and fast to administer, and it is a useful tool to stratify patients in terms of who is at the highest risk of developing complications related to the mTBI.

Introduction: Datura stramonium poisoning, resulting from the ingestion of seeds, leaves, or flowers of Datura stramonium, is a severe condition with significant risks, particularly for young children. Most documented cases of Datura stramonium poisoning in the literature involve teenagers who intentionally ingest the plant to induce hallucinogenic and euphoric experiences. This report presents a rare instance of unintentional Datura stramonium poisoning in a 3year-old Ethiopian toddler.

Case presentation: He presented with symptoms consistent with anticholinergic toxidrome, including altered mental status, agitation, seizures, dilated pupils, and tachycardia. Laboratory tests, including complete blood count, liver function test, renal function test, electrolyte levels and cerebrospinal fluid analysis were normal. Results of blood toxicology screen were negative. Timely recognition and supportive care lead to a positive outcome.

Conclusion: Through this report, we aim to add to the limited body of literature on Datura stramonium poisoning in toddlers and offer insights into its clinical course and management in paediatric patients.

Introduction: Mild traumatic brain injury (mTBI) represents a major public health concern and affects millions of people worldwide every year. Diagnosis mainly relies on clinical criteria and computed tomography (CT) scans. GFAP (glial fibrillary acidic protein) and UCH-L1 (ubiquitin carboxyl-terminal hydrolase-L1) have been recently studied as potential biomarkers of mTBI. This study retrospectively evaluated the possible use of these combined biomarkers as negative predictors for excluding brain injuries in patients with suspected mTBI in the emergency department.

Methods: Adult patients (n = 130) enrolled at Tor Vergata University Hospital (Rome, Italy), consecutively registered at the triage of the emergency department between October 2022 and January 2023, with non-penetrating TBI and Glasgow Coma Scale (GCS) score of 13-15, were considered. All eligible patients underwent intracranial CT scans and blood tests, within 12 h after trauma, for GFAP and UCH-L1 serum concentrations.

Results: Intracranial CT detected injuries in only seven patients (5%); GFAP and UCH-L1 tested positive in 96 patients and negative in 34 patients (74% vs. 26%). Combined biomarkers had a sensitivity equal to 1.00 (95% CI 0.64-1.00) and a negative predictive value (NPV) of 1.00 (0.99-1.00) in mTBI diagnosis with a negative CT.

Conclusions: Combined laboratory tests for GFAP and UCH-L1 biomarkers might play a potential clinical role in avoiding unnecessary head CT scans after mTBI in emergency departments.

Background: Communication between nurses and physicians is essential to providing patient care in the emergency department. The American College of Graduate Medical Education includes interpersonal and communication skills as one of six core competencies for residents. There is a known correlation between poor communication and negative patient outcomes. Yet, formalized training programs in doctor-nurse communication are lacking and literature reports that physicians may view collaboration as less important than nurses. To address this gap, we developed and implemented a novel, pilot "Nurse-InteRN Mentorship Program". The program aimed to improve trainees' communication with nurses and enhance emergency department collaboration. We then evaluated the impact of this program on participant perception of nurse-physician communication, efficacy and overall benefit.

Methods: We used Kern's Six-step approach to develop and implement this program. We then evaluated the program's impact with a pre-program and post-program 12-question survey to evaluate participation, perceived benefit, and efficacy of the program using a 1-5 Likert scale. Nurse vs. intern responses were compared using Fisher's exact and Wilcoxon rank sum tests. Pre- and post- intervention responses were paired by respondent and compared using marginal homogeneity tests.

Results: 13 interns and 22 nurses participated in the program. All 13 interns and 19 of 22 nurses completed the pre-program survey. 10 of 13 interns and 11 of 22 nurse mentors completed the post-program survey. Nurses showed greater interest in providing feedback on communication skills than interns showed in receiving feedback (p < 0.001). Interns rated themselves higher in communication skills with patients than nurses rated them (p = 0.004). Perceived benefit among nurses and interns decreased after completion of the program.

Conclusion: We were able to successfully implement a one-year nurse-intern mentorship program aiming to promote communication, collaboration and professional development. Our results show differing attitudes between nurses and interns around interns' communication skills. There was some perceived benefit, but unfortunately this decreased over the course of the program. Further studies are needed to determine how this program impacts communication, teamwork, and patient care. We hope that given the novelty of such a nurse-intern mentorship program, this study may serve as a pilot for future programs.
