Introduction: There is an evidence-practice gap in the optimal timing and volume of intravenous fluid as well as vasopressor administration in managing patients with sepsis. This study aimed to explore current hemodynamic resuscitation practice in emergency department (ED) for patients with sepsis and hypotension.

Methods: This is a sub-analysis of the prospective multicentre ARISE FLUIDS observational study, which was conducted in 70 EDs across Australia and New Zealand. Baseline characteristics, as well as ED management and outcome of sepsis patients were compared between patients who were and were not admitted to intensive care unit (ICU) or high dependency unit (HDU).

Results: A total of 587 patients with a median age of 65 years and even sex distribution (49% female) were available for analysis. Almost two-thirds of patients with sepsis (63.2%, n=371) were not admitted to ICU/HDU and were given lower intravenous (IV) fluid volumes over 24-hours, compared to those receiving critical care (4077ml vs. 5421ml, p<0.001). Patients not admitted to an ICU/HDU had a lower Acute Physiology And Chronic Health Evaluation (APACHE) II score (median 14 vs. 18, P<0.001) and serum lactate level (1.8 vs. 2.8 mmol/L, P<0.001) compared to those admitted to ICU/HDU and 5.9% received a vasopressor infusion in the first 24-hours. Females, patients aged <65 years, and those with urosepsis or sepsis of non-respiratory origin received a greater volume of IV fluids.

Conclusion: Almost two-thirds of patients were not admitted to ICU/HDU. In patients not admitted to ICU/HDU, 1 in 17 received a vasopressor infusion during their ED or early hospital stay. Patients not admitted to ICU/HDU received less fluid in the first 24 hours than those who were. Greater resuscitation fluid volumes were independently associated with female sex, age <65 years, higher lactate levels, and urinary or non-respiratory source of sepsis.

Introduction: As the quality of care for respiratory diseases in pediatric patients in emergency departments (EDs) becomes increasingly important, this systematic review aims to evaluate the current quality indicators (QIs) specifically designed for the ED management of pediatric bronchiolitis and croup.

Methods: We conducted searches in four electronic databases (Scopus, Web of Science, CINAHL, and MEDLINE) from their inception up to February 2024. We focused on English-language qualitative and quantitative publications that suggested or described at least one indicator initiative related to ED care for pediatrics with bronchiolitis and croup diseases. These publications were identified by two reviewers, independently. We extracted study characteristics, all relevant QIs reported, and the percentage of compliance with these QIs, where available. All QIs identified from expert panels and observational studies were grouped by definition and categorized by the Institute of Medicine's (IOM) and Donabedian's frameworks for healthcare quality. The percentage of compliance with the identified QIs as reported by observational studies was pooled using a random effect meta-analysis, when appropriate.

Results: A total of 17 studies were identified, comprising 5 expert panel studies and 12 observational studies. Altogether, these studies reported 126 QIs for potential use in EDs for pediatric bronchiolitis and croup patients. Of these, 55 QIs were reported by expert panel studies, and 71 by observational studies. Specifically, 81 QIs were related to bronchiolitis, while 45 pertained to croup patients. In terms of the Donabedian domain, most indicators (96.5%) measured the process of care while a smaller fraction (3.5%) addressed care outcomes. In the Institute of Medicine (IOM) domain, most indicators focused on effectiveness and safety. Observational studies reported the percentage of compliance for 35 QIs identified in the expert studies. It was noted that compliance with these QIs varied significantly between studies and health sectors.

Conclusions: The findings of this systematic review highlight significant disparities in compliance to the established QIs, which underscores the urgent need for dedicated strategies to enhance the treatment of pediatric bronchiolitis and croup in ED settings.

Introduction: Early discharge from the emergency department (ED) or a 6-hour observation in the ED are two methods for management of patients with mild traumatic brain injury (mTBI) with normal brain computed tomography (CT) scan. This study aimed to compare the outcomes of the two management options.

Methods: This study is a single-center, open-label, pilot randomized case control study conducted in the ED of Ramathibodi Hospital from June 2022 to September 2023. Eligible participants included all individuals with mTBI who had negative findings on Brain CT scans. They were randomly assigned to either the early ED discharge or 6-hour ED observation group and compared regarding the outcomes (rate of 48-hour ED revisits; occurrence of post-concussion syndrome (PCS) 1 day, 1 month, and 3 months after the initial injury; and 3-month mortality).

Results: 122 patients with the mean age of 74.62 ± 14.96 (range: 25-99) years were consecutively enrolled (57.37% female). No significant differences were observed between the early discharge and observation groups regarding the severity of TBI (p=0.853), age (p=0.334), gender (p=0.588), triage level (p=0.456), Glasgow Coma Scale (GCS) score (p=0.806), comorbidities (p=0.768), medication usage (p=0.548), mechanism of injury (p=0.920), indication for brain CT scan (p=0.593), time from TBI onset to ED arrival (p=0.886), and time from ED triage to brain CT scan (p=0.333). Within 48 hours after randomization, the incidence of revisits was similar between the two groups (1.57% vs. 3.23%; p = 1.000). There were no statistically significant differences in the incidence of PCS between the early discharge and observation groups at 1 day (33.90% vs. 35.48%, p = 0.503), at 1 month (12.07% vs. 13.11%, p = 0.542), and at 3 months (1.92% vs. 5.56%, p = 0.323) after randomization. After a three-month follow-up period, four patients in the early discharge group, had expired (none of the deaths were associated with TBI).

Conclusion: It seems that, in mTBI patients with normal initial brain CT scan and the absence of other injuries or neurological abnormalities, early discharge from the ED without requiring observation could be considered safe.

Introduction: Various treatment protocols have been recommended since the beginning of the COVID-19 pandemic and have gradually evolved. This study aimed to assess the effectiveness and safety of incentive spirometer exercise (ISE) in outcomes of hospitalized patients with moderate-to-severe COVID-19 pneumonia.

Methods: A 3-month single-blind, two parallel-armed randomized controlled trial was conducted at Imam Hossein Hospital, Tehran, Iran. Participants aged >18 years with documented COVID-19 pneumonia were randomly allocated to 2 groups of IS (ISE in addition to the usual treatment) and control (usual care alone). The IS group was also asked to perform ISE after discharge for three months. The primary outcomes were peripheral O2 saturation (SpO2), VBG parameters (pCO2, PH, HCO3), dyspnea level measured by Modified Borg Scale (MBS), length of hospital stay (LOS), and respiratory rate (RR). Secondary outcomes included mortality rate, intubation rate (IR), and ICU admission rate.

Results: A total of 160 eligible patients were randomly assigned to either the IS (n = 80) or control (n=80) groups. Although there were no significant differences in primary and secondary outcomes between the groups post-intervention, adjusted analysis showed that participants allocated to the IS group had significantly higher SpO2 levels and lower RR, MBS levels, and LOS. Also, the adjusted model analysis showed a marginal statistically significant difference between groups in secondary outcomes, such as IR, the 1-month mortality rate, and the 3-month mortality rate.

Conclusion: It seems that adding the ISE to usual care in the early treatment setting of COVID-19 patients resulted in a relatively significant increase in SpO2 levels, improved respiratory status, and marginally decreased LOS. Additionally, ISE minimally reduced ICU admissions and intubation rates, with no significant impact on in-hospital or long-term mortality in patients with COVID-19 pneumonia.

Introduction: Pelvic ring fractures categorized under Tile Categories B and C denote partially and fully unstable fractures, respectively. This study aimed to identify the clinically associated factors of Tile B/C pelvic ring fractures.

Methods: This retrospective cross-sectional study reviewed medical records from the Emergency Medicine department at Ramathibodi Hospital in Bangkok, Thailand. The study included individuals aged ≥ 15 who experienced accidents from 2012 to 2021. To investigate the associations between the clinical variables and three critical outcomes, including Tile B/C pelvic ring fractures, major vascular injuries, and the necessity for surgical or radiological interventions, multivariable logistic regression analysis was employed.

Results: A total of 198 patients were included in the study, among whom 34.8% were diagnosed with Tile B/C pelvic ring fractures. The analysis revealed several significant predictors of Tile B/C fractures, including the presence of pelvic tenderness (adjusted odds ratio [aOR] = 15.25, 95% confidence interval [CI] = 5.86-39.66, p < 0.001), and a shock index (SI) ≥1 (aOR = 4.2, 95% CI = 1.24-14.22, p = 0.021). Moreover, Tile B/C pelvic ring fractures were associated with an increased incidence of major vascular events and the imperative requirement for surgical or radiological interventions.

Conclusion: Clinical findings of pelvic tenderness and an SI ≥1 are strong predictive clinical factors associated with Tile B/C pelvic fractures. Early diagnosis, application of an pelvic binder, provision of initial resuscitation, and prompt transportation to a definitive care facility are crucial components of management.

Introduction: Chinese populations have an increasingly high prevalence of cardiac arrest. This study aimed to investigate the prehospital associated factors of survival to hospital admission and discharge among out-of-hospital cardiac arrest (OHCA) adult cases in Macao Special Administrative Region (SAR), China.

Methods: Baseline characteristics as well as prehospital factors of OHCA patients were collected from publicly accessible medical records and Macao Fire Services Bureau, China. Demographic and other prehospital OHCA characteristics of patients who survived to hospital admission and discharge were analyzed using multivariate logistic regression analysis.

Results: A total of 904 cases with a mean age of 74.2±17.3 (range: 18-106) years were included (78%>65 years, 62% male). Initial shockable cardiac rhythm was the strongest predictor for survival to both hospital admission (OR=3.57, 95% CI: 2.26-5.63; p<0.001) and discharge (OR=12.40, 95% CI: 5.70-26.96; p<0.001). Being male (OR=1.63, 95% CI:1.08-2.46; p =0.021) and the lower emergency medical service (EMS) response time (OR=1.62, 95% CI: 1.12-2.34; p =0.010) were also associated with a 2-fold association with survival to hospital admission. In addition, access to prehospital defibrillation (OR=4.25, 95% CI: 1.78-10.12; p <0.001) had a 4-fold association with survival to hospital discharge. None of these associations substantively increased with age.

Conclusion: The major OHCA predictors of survival were initial shockable cardiac rhythm, being male, lower EMS response time, and access to prehospital defibrillation. These findings indicate a need for increased public awareness and more education.

Introduction: The COVID-19 pandemic caused by SARS-CoV-2 has been the major health concern in 2019 globally. Considering the severity and phase of the disease, various pharmacotherapy schedules were proposed. Here, we set out to provide close-up insights on the clinical utility of Tocilizumab (TCZ), a biologic monoclonal antibody in this regard.

Methods: In this comprehensive review, various databases, including Scopus, PubMed Central, Medline, Embase, Google Scholar, and preprint publishers (med/bioRxiv) were searched until January 30, 2024, according to the keywords and search criteria.

Results: Besides the pros and cons, compelling evidence purported the safety and efficacy of TCZ and indicated that it exhibits great potential to reduce short-term and all-cause (28-30-day) mortality. TCZ significantly drops the adverse events if administered in the right time course (in the inflammatory phase) during critical/severe COVID-19 pneumonia. Despite contradictory results, the benefits of TCZ appear significant, especially in combination with add-on therapies, such as corticosteroids. Although the safety of TCZ is acceptable, solid data is lacking as to its benefits during pregnancy. There are limited data on TCZ combination therapies, such as hemoperfusion, intravenous immunoglobulin (IVIG), simple O2 therapy, vasopressor support, convalescent plasma therapy, and even in vaccinated patients and COVID-19 reinfection, especially in elderly persons. In addition, the impact of TCZ therapy on the long-lasting COVID-19 is unclear.

Conclusion: Personalized medicine based on individual characteristics and pertinent clinical conditions must be considered in the clinicians' decision-making policy. Finally, to mitigate the risk-to-benefit ratio of TCZ, a treatment algorithm, based on available literature and updated national institute of health (NIH) and Infectious Diseases Society of America (IDSA) guidelines, is also proposed.

Carotid complications resulting from extra-luminal migration of ingested foreign bodies (FB) are rare but potentially life-threatening. Previous data on the topic predominantly comprises isolated case reports, leaving a gap in comprehensive evidence necessary to guide clinical decision-making. In this article, we offer a narrative review alongside a novel case report, aimed at providing a broad, evidence-based perspective on the topic to guide clinical practice. The search strategy employed keywords related to carotid artery complications from ingested FB across the following electronic databases: PubMed, Scopus, Google Scholar, and Cochrane Central. Screening involved standardized data extraction by two independent reviewers, with a focus on abstracts meeting inclusion criteria and excluding non-English literature and non-relevant studies from further analysis. Moreover, we present a novel case report on the topic that was successfully managed using a unique surgical approach. Overall, a total of sixteen case reports were finally included, data on clinical presentations, diagnostic strategies and findings, surgical management and outcome were extracted, tabulated, and discussed. In carotid complications from extra-luminal migration of ingested FB, high clinical suspicion is crucial due to potentially mild symptoms and negative first-level examinations. Computed tomography (CT) scan plays a pivotal role for accurate diagnosis and surgical planning, along with neck ultrasound to detect complications. Tailored surgical strategies based on the severity of carotid involvement, including venous patch grafts in severe vessels involvement, are crucial for optimal patient outcomes. As a novelty, in our case report, carotid shunt was successfully employed instead of prolonged carotid clamping to reduce the risk of associated neurological sequelae. It could be concluded that, diagnosis and managing carotid complications from extra-luminal migration of ingested FB remains challenging and a multidisciplinary approach is warranted.

Introduction: Distinguishing between ruptured and non-ruptured acute appendicitis presents a significant challenge. This study aimed to validate the accuracy of RAMA-WeRA Risk Score in predicting ruptured appendicitis (RA) in emergency department.

Methods: This study was a multicenter diagnostic accuracy study conducted across six hospitals in Thailand from February 1, 2022, to January 20, 2023. The eligibility criteria included individuals aged >15 years suspected of acute appendicitis, presenting to the ED, and having an available pathology report following appendectomy or intraoperative diagnosis by the surgeon. We assessed the screening performance characteristics of RAMA-WeRA Risk Score, in detecting the ruptured appendicitis (RA) cases.

Results: 860 patients met the study criteria. 168 (19.38%) had RA and 692 (80.62%) patients had non-RA. The area under the receiver operating characteristic curve (AuROC) of RAMA-WeRA Risk Score was 75.11% (95% CI: 71.10, 79.11). The RAMA-WeRA Risk Score > 6 points (high-risk group) demonstrated a positive likelihood ratio (LR) of 3.22 in detecting the ruptured cases. The sensitivity and specificity of score in > 6 cutoff point was 43.8% (95%CI: 36.2, 51.6) and 86.4% (95%CI: 83.6, 88.9), respectively.

Conclusions: The RAMA-WeRA Risk Score can predict rupture in patients presenting with suspected acute appendicitis in the emergency department with total accuracy of 75% for high-risk cases.

Introduction: Infectious diarrhea, a significant global health challenge, is exacerbated by flooding, a consequence of climate change and environmental disruption. This comprehensive study aims to quantify the association between flooding events and the incidence of infectious diarrhea, considering diverse demographic, environmental, and pathogen-specific factors.

Methods: In this systematic review and meta-analysis, adhering to PROSPERO protocol (CRD42024498899), we evaluated observational studies from January 2000 to December 2023. The analysis incorporated global data from PubMed, Scopus, Embase, Web of Science, and ProQuest, focusing on the relative risk (RR) of diarrhea post-flooding. The study encompassed diverse variables like age, sex, pathogen type, environmental context, and statistical modeling approaches.

Results: The meta-analysis, involving 42 high-quality studies, revealed a substantial increase (RR = 1.40, 95% CI [1.29-1.52]) in the incidence of diarrhea following floods. Notably, bacterial and parasitic diarrheas demonstrated higher RRs (1.82 and 1.35, respectively) compared to viral etiologies (RR = 1.15). A significant sex disparity was observed, with women exhibiting a higher susceptibility (RR = 1.55) than men (RR = 1.35). Adults (over 15 years) faced a greater risk than younger individuals, highlighting age-dependent vulnerability.

Conclusion: This extensive analysis confirms a significant correlation between flood events and increased infectious diarrhea risk, varying across pathogens and demographic groups. The findings highlight an urgent need for tailored public health interventions in flood-prone areas, focusing on enhanced sanitation, disease surveillance, and targeted education to mitigate this elevated risk. Our study underscores the critical importance of integrating flood-related health risks into global public health planning and climate change adaptation strategies.
