Abstract
BACKGROUND Emergency Department (ED) overcrowding is a global concern, with tools like NEDOCS, READI, and Work Score used as predictors. These tools aid healthcare professionals in identifying overcrowding and preventing negative patient outcomes. However, there's no agreed-upon method to define ED overcrowding. Most studies on this topic are U.S.-based, limiting their applicability in EDs without waiting rooms or ambulance diversion roles. Additionally, the intricate calculations required for these scores, with multiple variables, make them impractical for use in developing nations. OBJECTIVE This study sought to examine the relationship between prevalent ED overcrowding scores such as EDWIN, occupancy rate, and Work Score, and a modified version of EDWIN newly introduced by the authors, in comparison to the real-time perspectives of emergency physicians. Additionally, the study explored the links between these overcrowding scores and adverse events related to ED code activations as secondary outcomes. METHOD The method described in the provided text is a correlational study. The study aims to examine the relationship between various Emergency Department (ED) overcrowding scores and the real-time perceptions of emergency physicians in every two-hour period. Additionally, it seeks to explore the associations between these scores and adverse events related to ED code activations. RESULTS The study analyzed 459 periods, with 5.2% having Likert scores of 5-6. EDOR had the highest correlation coefficient (0.69, p < 0.001) and an AUC of 0.864. Only EDOR significantly correlated with adverse events (p = 0.033). CONCLUSION EDOR shows the most robust link with 'emergency physicians' views on overcrowding. Additionally, elevated EDOR scores correlate with a rise in adverse events. Emergency physicians' perceptionof overcrowding could hint at possible adverse events. Notably, all overcrowding scores have high negative predictive values, efficiently negating the likelihood of adverse incidents.

Abstract
BACKGROUND AND OBJECTIVE Several studies suggest that air pollution, particularly PM2.5, increases morbidity and mortality, Emergency Department (ED) visits, and hospitalizations for acute respiratory and cardiovascular diseases. However, no prior study in Southeastern Asia (SEA) has examined the effects of air pollutants on ED visits and health outcomes. This study focused on the association of the Air Quality Index (AQI) of PM2.5 and other pollutants' effects on ED visits, hospitalization, and unexpected deaths due to acute respiratory disease, acute coronary syndrome (ACS), acute heart failure (AHF), and stroke. METHODS We conducted a retrospective study with daily data from ED visits between 2018 and 2019 at Maharaj Nakorn Chiang Mai Hospital, Chiang Mai, Thailand. The AQI of air pollution data was collected from outdoor air quality from the Smoke Haze Integrated Research Unit and the Air Quality Index Visual Map. A distributed lag, non-linear and quasi-Poisson models were used to explore the relationship between air quality parameters and ED visits for each disease. RESULTS 3,540 ED visits were recorded during the study period. The mean daily AQI of PM2.5 was 89.0 ± 40.2. We observed associations between AQI of PM2.5 and the ED visits due to ACS on the following day (RR = 1.023, 95% confidence interval [CI]: 1.002-1.044) and two days after exposure (RR = 1.026, 95% CI: 1.005-1.047). Also, subgroup analysis revealed the association between AQI of PM2.5 and the ED visits due to pneumonia on the current day (RR = 1.071, 95% CI: 1.025-1.118) and on the following day after exposure (RR = 1.024, 95% CI: 1.003-1.046). AQI of PM2.5 associated with increased mortality resulted from ACS on lag day 3 (OR = 1.36, 95% CI: 1.08-1.73). The AQI of PM10 is also associated with increased ED visits due to COPD/asthma and increased hospitalization in AHF. In addition, the AQI of O3 and AQI of NO2 is associated with increased ICU admissions and mortality in AHF. CONCLUSION Short-term PM2.5 exposure escalates ED visits for ACS and pneumonia. PM10's AQI associates with COPD/asthma ED visits and AHF hospitalizations. AQI of O3 and NO2's link to increased ICU admissions and AHF mortality. Urgent action against air pollution is vital to safeguard public health.

Abstract
BACKGROUND Extracorporeal cardiopulmonary resuscitation (ECPR) is commonly initiated for adults experiencing cardiac arrest within the cardiac catheterization lab or the intensive care unit. However, the potential benefit of ECPR for these patients in the emergency department (ED) remains undocumented. This study aims to assess the benefit of ECPR initiated in the ED for patients with out-of-hospital cardiac arrest (OHCA). METHODS We conducted a systematic review and meta-analysis of studies comparing ECPR initiated in the ED versus conventional CPR. Relevant articles were identified by searching several databases including PubMed, EMBASE, Web of Science, and Cochrane collaborations up to July 31, 2022. Pooled estimates were calculated using the inverse variance heterogeneity method, while heterogeneity was evaluated using Q and I2 statistics. The risk of bias in included studies was evaluated using validated bias assessment tools. The primary outcome was a favorable neurological outcome at hospital discharge, and the secondary outcome was survival to hospital discharge or 30-day survival. Sensitivity analyses were performed to explore the benefits of ED-initiated ECPR in studies utilizing propensity score (PPS) analysis. Publication bias was assessed using Doi plots and the Luis Furuya-Kanamori (LFK) index. RESULTS The meta-analysis included a total of eight studies comprising 51,173 patients. ED-initiated ECPR may not be associated with a significant increase in favorable neurological outcomes (odds ratio [OR] 1.43, 95% confidence interval [CI] 0.30-6.70, I2 = 96%). However, this intervention may be linked to improved survival to hospital discharge (OR 3.34, 95% CI 2.23-5.01, I2 = 17%). Notably, when analyzing only PPS data, ED-initiated ECPR demonstrated efficacy for both favorable neurological outcomes (OR 1.89, 95% CI 1.26-2.83, I2 = 21%) and survival to hospital discharge (OR 3.37, 95% CI 1.52-7.49, I2 = 57%). Publication bias was detected for primary (LFK index 2.50) and secondary (LFK index 2.14) outcomes. CONCLUSION The results of this study indicate that ED-initiated ECPR may not offer significant benefits in terms of favorable neurological outcomes for OHCA patients. However, it may be associated with increased survival to hospital discharge. Future studies should prioritize randomized trials with larger sample sizes and strive for homogeneity in patient populations to obtain more robust evidence in this area.

Abstract
Background: Hypokalemia is associated with considerable morbidity and mortality, highlighting the timely correction of potassium levels as a critical medical consideration. However, the management of mild hypokalemia remains a subject of ongoing debate. This study explores the relationship between potassium replacement in the emergency department (ED) and hospital mortality in patients with mild hypokalemia. Methods: This retrospective cohort study was conducted at a tertiary care hospital, including patients who presented to the ED with mild hypokalemia, defined as potassium levels between 3.0 and 3.4 mmol/L, between 2020 and 2021. Patients diagnosed with acute coronary syndrome, diabetic ketoacidosis, hyperglycemic hyperosmolar state, and major cardiac arrhythmias were excluded. The patient cohort was then divided into two groups, based on whether they received potassium replacement in the ED. A propensity score analysis was employed to account for potential pretreatment confounding factors, including age, gender, time on ED arrival, insurance, comorbidities, serum potassium and creatinine levels, and ED length of stay. Subsequently, a multivariable logistic regression analysis, incorporating hospital length of stay and acute comorbidities, was performed post-matching to further adjust for predictive factors. The primary outcome was all-cause hospital mortality. Results: This study included a total of 1931 patients, of which 724 were matched for analysis (362 with potassium replacement and 362 without). The average age was 53.9 years, and most were male (58.5%). After adjusting for confounding factors using propensity score analysis, there was no significant difference in hospital mortality between the potassium replacement and control groups (adjusted odds ratio 0.81, 95% CI 0.36-1.79, p = 0.60). Conclusions: This study's findings indicate that replacing potassium in the ED may not lower the risk of hospital mortality in patients with mild hypokalemia. Consequently, the customary practice of potassium replacement in hospitalized patients may lack justification, and deferring the replacement until after patients leave the ED could be considered.

Abstract
Introduction Accurate assessment and management of abdominal pain in the emergency department (ED) is crucial, as it can indicate potentially life-threatening conditions requiring timely treatment. This study aimed to evaluate the ability of pain scales to predict critical diagnoses in patients with non-traumatic abdominal pain. Methods This cross-sectional study was conducted at a tertiary university hospital and involved individuals aged 15 years and above who presented to the ED with non-traumatic abdominal pain. Pain severity was evaluated using subjective pain scales, including the Numerical Rating Scale (NRS) and the Face Pain Scale (FPS), as well as objective pain scales, including the Critical Care Pain Observation Tool (CPOT) and the Non-verbal Pain Score (NVPS). The area under the receiver operating characteristic curve (AuROC) was employed to determine the discriminative ability of each pain scale to predict critical diagnosis. Results 264 cases with the mean age of 47.2±19.4 years were studied (53.0% male). The most common location of abdominal pain was epigastric pain (43.9%). Most patients presented with dull-aching pain, and those with critical diagnoses had more of this characteristic than those with non-critical diagnoses. (52.5% vs. 28.3%, p = 0.01). The overall median NRS, FPS, CPOT, and NVPS of included participants were 8 (interquartile range (IQR) 7-10), 8 (IQR 6-8), 3 (IQR 1-4), and 3 (IQR 2-4), respectively. Patients with critical diagnoses had a higher NVPS score than patients with non-critical diagnoses (median score of 4 vs. 3, p = 0.02). The AuROC of NRS, FPS, CPOT, and NVPS were 0.53 (95% CI: 0.45-0.62), 0.55 (95% CI: 0.46-0.63), 0.59 (95% CI: 0.50-0.68), and 0.62 (95% CI: 0.53-0.71), respectively. The correlation coefficients among these scales were considered moderately correlated or higher. Conclusion In evaluating patients with non-traumatic abdominal pain, the NVPS demonstrated the highest accuracy in predicting critical diagnoses. However, all pain scales, whether subjective or objective, exhibited suboptimal performance in predicting critical diagnoses.

Abstract
Probiotics have the potential as a multi-target approach to modulate hypercholesterolemia associated with premature atherosclerosis. Various strains of Lactobacillus paracasei have been reported to affect hypercholesterolemia positively. This study aimed to investigate the effects of L. paracasei TISTR 2593 on lipid profile, cholesterol metabolism, and atherosclerosis according to the registration of Thai Clinical Trial Registry as identification number TCTR 20220917002. A total of 50 participants with hypercholesterolemia were randomly and equally assigned to consume L. paracasei TISTR 2593 or a placebo in maltodextrin capsules daily. Biomarkers of lipid profiles, oxidative stress state, inflammatory state, and other biological indicators were examined on days 0, 45, and 90. The results showed that subjects taking the L. paracasei TISTR 2593 could significantly reduce the level of serum low-density lipoprotein-cholesterol (p < 0.05), malondialdehyde (p < 0.001), and tumor necrosis factor-α (p < 0.01). Moreover, L. paracasei TISTR 2593 increased the level of serum apolipoprotein E (p < 0.01) and adiponectin (p < 0.001) significantly. No changes in serum total cholesterol, high-density lipoprotein-cholesterol, triglyceride, total bile acids, and monocyte chemoattractant protein-1 were observed during L. paracasei TISTR 2593 supplementation. Therefore, L. paracasei TISTR 2593 could be an adjuvant probiotic supplement to ameliorate hypercholesterolemia and prevent or delay the development of atherosclerosis.

Abstract
Current guidelines for treating cardiac arrest recommend administering 1 mg of epinephrine every 3−5 min. However, this interval is based solely on expert opinion. We aimed to investigate the impact of the epinephrine administration interval (EAI) on resuscitation outcomes in adults with cardiac arrest. We systematically reviewed the PubMed, EMBASE, and Scopus databases. We included studies comparing different EAIs in adult cardiac arrest patients with reported neurological outcomes. Pooled estimates were calculated using the IVhet meta-analysis, and the heterogeneities were assessed using Q and I2 statistics. We evaluated the study risk of bias and overall quality using validated bias assessment tools. Three studies were included. All were classified as “good quality” studies. Only two reported the primary outcome. Compared with a recommended EAI of 3−5 min, a favorable neurological outcome was not significantly different in patients with the other frequencies: for <3 min, odds ratio (OR) 1.93 (95% CI: 0.82−4.54); for >5 min, OR 1.01 (95% CI: 0.55−1.87). For survival to hospital discharge, administering epinephrine for less than 3 min was not associated with a good outcome (OR 1.66, 95% CI: 0.89−3.10). Moreover, EAI of >5 min did not pose a benefit (OR 0.87, 95% CI: 0.68−1.11). Our review showed that EAI during CPR was not associated with better hospital outcomes. Further clinical trials are necessary to determine the optimal dosing interval for epinephrine in adults with cardiac arrest.

Abstract
Low blood sugar is commonly found during cardiopulmonary resuscitation (CPR). However, current guidelines do not mention the importance of glucose testing and acute management for hypoglycemia during CPR. We intended to investigate the association between dextrose administration and resuscitation outcomes in patients with blood sugar less than 150 mg/dL during cardiac arrest in the emergency department (ED). We conducted a retrospective cohort study at a tertiary hospital between 2017 and 2020, including patients with intra-arrest blood glucose <150 mg/dL. Logistic regression with inverse probability treatment weighting (IPTW) was used. The primary outcome was the return of spontaneous circulation (ROSC). Secondary outcomes included survival to hospital admission and hospital discharge and favorable neurological outcomes at discharge. A total of 865 patients received CPR at the ED during the study period. Of these, 229 with low blood sugar were included (60 in the treatment group and 169 in the non-treatment group). The mean age was 59.5 ± 21.4 years. After IPTW, dextrose administration during CPR was not associated with ROSC (adjusted OR [aOR] 1.44, 95% CI 0.30−0.69), survival to hospital admission (aOR 1.27, 95% CI 0.54−3.00), survival to hospital discharge (aOR 0.68, 95% CI 0.20−2.29), and favorable neurological status (aOR 2.21, 95% CI 0.23−21.42). Our findings suggested that dextrose administration during CPR at the ED might not lead to better or worse resuscitation outcomes. Owing to the design limitations and residual confounding factors, strong recommendations for dextrose administration could not be formulated. Further evidence is needed from prospective trials to confirm the efficacy of dextrose during CPR.

Abstract
BACKGROUND Out-of-hospital cardiac arrest (OHCA) is not common but associated with a low survival rate. There is no evidence investigating the effects of previous Basic Life Support (BLS) training among long-distance runners. The goal of this study is to demonstrate the health characteristics, knowledge, and attitudes towards BLS among marathon runners. METHODS An online cross-sectional survey was asked to all 2019 Chiang Mai University marathon participants as a part of the running registration. Details of health characteristic, running history, and BLS training details were requested. The primary outcomes were knowledge and attitude towards BLS among marathon runners. RESULTS Of all 10,507 questionnaires sent, the response rate was 92.9%. One-nineth of participants were 50 years of age or above. The mean age was 36.8±9.9 years. Most were male (56.1%) and Thai (99.4%). Only a quarter (2454 out of 9761 runners) of study population had previous BLS training. Family history of sudden cardiac death or cardiac death with unknown causes was more in participants with previous BLS training than those without (1.1% vs. 0.6%, P=0.01). Previous BLS training group answered the national emergency call number correctly more than those without (90.4% vs. 73.0%, P<0.001) and previous BLS training group were more likely to initiate CPR than those without (median self-confidence 8 vs. 5, respectively, P<0.001). CONCLUSIONS Only a quarter of running participants have participated in BLS training before entering a marathon running. Having previous BLS training is associated with higher self-confidence to attempt CPR. Organized planning including trained medical staff, adequate equipment, and qualified bystanders is recommended.

Abstract
The 2019 coronavirus disease (COVID-19), resulting from the severe acute respiratory syndrome 2 virus, has transformed our globe and provided a new perspective on respiratory tract infections. However, COVID-19 would not be recognized as a condition restricted to only pneumonia. This narrative review was conducted by searching manuscripts in several databases, including PubMed/ MEDLINE, Web of Science, and Reference Citation Analysis, from December 2019 to July 2022. Many studies have revealed a broad spectrum of potential systemic symptoms, including biliary complications. Although biliary injury has been observed in a very low proportion of COVID-19 patients, it is associated with increased mortalities and long-term morbidities. We identify a cholangiopathy condition in individuals during infection and after recovering from severe COVID-19, defined by a significant increase in serum alkaline phosphatase and signs of bile duct injury. Understanding the pathogeneses behind this condition would help us develop new techniques to prevent these complications. This review thoroughly discusses and summarizes the current information regarding COVID-19-associated cholangiopathy. In addition, the possible explanations for COVID-19-associated cholangiopathy are presented. Since the exact pathogenesis may not be concluded, this review could provide relevant information to encourage additional investigations shortly.

Abstract
BACKGROUND Several studies have demonstrated that the coronavirus disease 2019 (COVID-19) has affected daily living and the healthcare system. No previous study has described the consequences of COVID-19 on emergency department (ED) visits and hospital admission among kidney transplant (KT) recipients.
AIM To investigate the impact of the COVID-19 pandemic on ED visits and hospital admissions within 1 year in patients who underwent KT in Thailand.
METHODS We conducted a retrospective study at a university hospital in Thailand. We reviewed the hospital records of KT patients who visited the ED during the outbreak of COVID-19 (from January 2020 to December 2021). We used the previous 2 years as the control period in the analysis. We obtained baseline demographics and ED visit characteristics for each KT patient. The outcomes of interest were ED visits and ED visits leading to hospital admission within the 1st year following a KT. The rate of ED visits and ED visits leading to hospital admissions between the two periods were compared using the stratified Cox proportional hazards model.
RESULTS A total of 263 patients were included in this study: 112 during the COVID-19 period and 151 during the control period. There were 34 and 41 ED visits after KT in the COVID-19 and control periods, respectively. The rate of first ED visit at 1 year was not significantly different in the COVID-19 period, compared with the control period [hazard ratio (HR) = 1.02, 95% confidence interval (CI): 0.54-1.92; P = 0.96]. The hospital admission rate was similar between periods (HR = 0.92, 95%CI: 0.50-1.69; P = 0.78).
CONCLUSION ED visits and hospital admissions within the 1st year in KT recipients were not affected by the COVID-19 pandemic. Despite these findings, we believe that communication between post-KT patients and healthcare providers is essential to highlight the importance of prompt ED visits for acute health conditions, particularly in post-KT patients.

Abstract
BACKGROUND Metoclopramide may be used to treat people suffering from acute migraine. However, no comprehensive investigation on this issue has been recorded. This review will provide more solid evidence for the use of metoclopramide in treating acute migraine.
AIM To compare the efficacy of intravenous metoclopramide with other therapies in migraine attack treatment in an emergency department (ED).
METHODS We included randomized controlled trials of participants older than 18 years with acute migraine headaches, which included at least one arm that received intravenous (IV) metoclopramide at the ED. A literature search of PubMed, Web of Science, Cochrane Collaboration, and Reference Citation Analysis on December 31, 2021 retrieved other drugs or placebo-controlled studies without language limitation. The risk of bias was assessed using the Cochrane risk of bias tool. The primary endpoint was pain reduction at 60 min or closest to 1 h after treatment, as measured by the pain scale. Secondary endpoints included adverse effects or reactions resulting from metoclopramide or comparisons.
RESULTS Fourteen trials with a total of 1661 individuals were eligible for review. The risk of bias ranged from low to intermediate. IV metoclopramide administration was not associated with higher pain reduction at 1 h (Standard mean difference [SMD] = -0.03, 95% confidence interval [CI]: -0.33-0.28, P = 0.87). However, metoclopramide was associated with better pain reduction than placebo (SMD = 1.04, 95%CI: 0.50-1.58, P = 0.0002). In addition, side effects were not significantly different between IV metoclopramide and other drugs or placebo (odds ratio [OR] = 0.76, 95%CI: 0.48-1.19, P = 0.09 and OR = 0.92, 95%CI: 0.31-2.74, P = 0.54, respectively).
CONCLUSION Metoclopramide is more effective than placebo in treating migraine in the ED. Despite the observed tendency of decreased side effects, its effectiveness compared to other regimens is poorly understood. More research on this area is needed to treat migraine in acute care settings effectively.

Abstract
Since current cardiac arrest guidelines do not address the benefit of blood glucose measurement, the ideal ranges and target of blood glucose (BG) levels during cardiac arrest to achieve a better result are warranted. We intended to investigate the associations between intra-arrest BG levels and outcomes of cardiac arrest resuscitation at the emergency department (ED). We conducted a retrospective observational study at a single university hospital. Cardiac arrest patients at the ED between 2017 and 2020 were included. Multivariable logistic regression analysis was performed to examine the associations between intra-arrest BG levels and clinical outcomes. We categorized intra-arrest BG into five groups: <70 mg/dL, 70−99 mg/dL, 100−180 mg/dL, 181−250 mg/dL, and >250 mg/dL. Eight hundred and nineteen patients experienced ED cardiac arrest during the study period. Of all, 385 intra-arrest BG measurements were included in the data analysis. The mean age was 60.4 years. The mean intra-arrest BG level was 171.1 mg/dL, with 64 (16.6%) patients who had intra-arrest BG level below 70 mg/dL and 73 (19.0%) patients who had intra-arrest BG level more than 250 mg/dL. Markedly low (<70 mg/dL) and low (70−99 mg/dL) intra-arrest BG levels were significantly associated with a lower chance of return of spontaneous circulation (ROSC, OR 0.36, 95% CI 0.14−0.99, p = 0.05 and OR 0.33, 95% CI 0.12−0.93, p = 0.04, respectively). For patients who experienced cardiac arrest at the ED, an intra-arrest BG level of less than 100 was inversely correlated with sustained ROSC. Although we could not draw a causal relationship between variables concerning this study design, normalizing intra-arrest BG was shown to result in good clinical outcomes.

Abstract
OBJECTIVES Calcium administration during cardiac arrest is limited in some circumstances, mainly due to lack of consistent evidence. This study aims to investigate whether calcium therapy administered during cardiac arrest at the Emergency Department is associated with good outcomes, including the probability of return of spontaneous circulation (ROSC), survival to hospital admission, survival to hospital discharge, and favorable neurological outcome at discharge. METHODS We retrospectively reviewed 599 consecutive adult cardiac arrest events between 2016 and 2018. The primary outcome was the ROSC rate. Secondary outcomes included survival to hospital admission, survival to hospital discharge, and favorable neurologic outcome at hospital discharge. Multivariable logistic regression with inverse probability of treatment weighting was analyzed to examine the association between calcium administration and outcomes. RESULTS Of 599 events, calcium was administered in 72 (12%) cases. The use of calcium during cardiopulmonary resuscitation (CPR) after adjusting for confounding factors was not associated with any better outcomes, including ROSC (adjusted odds ratio (aOR) 0.53, 95% confidence interval [CI] 0.24-1.17), survival to hospital admission (aOR 1.07, 95% CI 0.47-2.41), survival to hospital discharge (aOR 1.93, 95% CI 0.43-8.56), and favorable neurological outcome (aOR 6.60, 95% CI 0.72-60.74). Besides, calcium use in traumatic cardiac arrest patients was associated with unfavorable outcomes, including ROSC (aOR 0.02, 95% CI 0.00-0.09) and survival to hospital admission (aOR 0.16, 95% CI 0.03-0.84). CONCLUSION The use of calcium during an adult cardiac arrest was not associated with better outcomes. Although associations drawn from this study did not indicate the causality, given calcium during CPR was linked to poorer outcomes in traumatic cardiac arrest patients, including ROSC and survival to hospital admission.

Abstract
OBJECTIVE This study aimed to explore significant pre-hospital factors affecting the survivability of Out-of-Hospital Cardiac Arrest (OHCA) patients in countries with developing EMS systems. METHOD A retrospective cohort study was conducted examining data from January 1, 2017 to December 31, 2020 from Utstein Registry databases in Thailand, collected through Pan-Asian Resuscitation Outcomes Study (PAROS). Data were collected from three centres, including regional, suburban-capital, and urban-capital hospitals. The primary endpoint of this study was 30-day survival or discharged alive after an OHCA event. The multivariable risk regression was done by modified Poisson regression with robust error variance to explore the association between 30-day survival and pre-hospital factors with potential confounders adjustments. FINDINGS Of 1,240 OHCA cases transferred by Emergency Medical Services (EMS), 42 patients (3.4%) were discharged alive after 30 days, including 22 (8.6%), 8 (3.0%), and 12 (1.7%) from regional, suburban-capital, and urban-capital centres, respectively. The initial arrest rhythm was 89.7% unshockable, with no significant variations across the three centres. Overall, bystander Cardiopulmonary Resuscitation (CPR) was 40.4%. However, bystander CPR with Automated External Defibrillator (AED) application was 0.8%. Bystander CPR significantly increased 30-day survival probability (aRR 1.88, 95% CI 1.01 to 3.51; p 0.049). Additionally, reducing the EMS response time by one minute significantly increased OHCA survivability (aRR 1.12, 95% CI 1.04 to 1.20; p 0.001). CONCLUSIONS Response time and bystander CPR are the factors that improve the 30-day survival outcomes of OHCA patients. In contrast, scene time, transport time, and pre-hospital advanced airway management didn't improve 30-day OHCA survival.

Abstract
INTRODUCTION Despite the standard guidelines stating that giving epinephrine for patients with cardiac arrest is recommended, the clinical benefits of epinephrine for patients with traumatic out-of-hospital cardiac arrest (OHCA) are still limited. This study aims to evaluate the benefits of epinephrine administration in traumatic OHCA patients. METHODS We searched four electronic databases up to June 30, 2020, without any language restriction in research sources. Studies comparing epinephrine administration for traumatic OHCA patients were included. Two independent authors performed the selection of relevant studies, data extraction, and assessment of the risk of bias. The primary outcome was inhospital survival rate. Secondary outcomes included prehospital return of spontaneous circulation (ROSC), short-term survival, and favorable neurological outcome. We calculated the odds ratios (ORs) of those outcomes using the Mantel-Haenszel model and assessed the heterogeneity using the I2 statistic. RESULTS Four studies were included. The risk of bias of the included studies was low, except for one study in which the risk of bias was fair. All included studies reported the inhospital survival rate. Epinephrine administration during traumatic OHCA might not demonstrate a benefit for inhospital survival (OR: 0.61, 95% confidence interval [CI]: 0.11-3.37). Epinephrine showed no significant improvement in prehospital ROSC (OR: 4.67, 95% CI: 0.66-32.81). In addition, epinephrine might not increase the chance of short-term survival (OR: 1.41, 95% CI: 0.53-3.79). CONCLUSION The use of epinephrine for traumatic OHCA may not improve either inhospital survival or prehospital ROSC and short-term survival. Epinephrine administration as indicated in standard advanced life support algorithms might not be routinely used in traumatic OHCA.

Abstract
BACKGROUND The clinical benefits of steroid administration during cardiac arrest remain unclear. Several studies reported that patients who received steroids after achieving a return of spontaneous circulation (ROSC) had better outcomes, but few studies have investigated the benefits of steroid administration during resuscitation. We hypothesized that administration of steroid during cardiac arrest would be associated with better clinical outcomes in adults with cardiac arrest.
AIM To investigate the effect of steroid administration during cardiac arrest and the outcomes of resuscitation.
METHODS We included studies of participants older than 18 years of age who experienced cardiac arrest and included at least one arm that received corticosteroids during cardiac arrest. A literature search of PubMed and Embase on 31 January 2021 retrieved placebo-controlled studies without limitation for type, location, and initial presenting rhythm of cardiac arrest. The study outcomes were reported by odds ratios (ORs) compared with placebo. The primary outcome was survival rate at hospital discharge. Secondary outcomes included a sustained ROSC, survival rate at hospital admission, and neurological outcome at hospital discharge.
RESULTS Six studies including 146262 participants were selected for analysis. The risk of bias ranged from low to high for randomized-controlled trials (RCTs) and low (for non-RCTs). Steroid administration was associated with increased survival at hospital discharge [OR: 3.51, 95% confidence interval (CI): 1.98-6.20, P < 0.001], and steroid administration during cardiac arrest was associated with both an increased rate of sustained ROSC (OR: 1.81, 95%CI: 1.91-4.02, P < 0.001) and a favorable neurological outcome at hospital discharge (OR: 3.02, 95%CI: 1.26-7.24, P = 0.01).
CONCLUSION Steroid administration during cardiac arrest was associated with better outcomes of resuscitation. Further study of the use of steroid in the selected circumstances are warranted.

Abstract
INTRODUCTION The benefit of medications used in out-of-hospital, shock-refractory cardiac arrest remains controversial. This study aims to compare the treatment outcomes of medications for out-of-hospital, shock-refractory ventricular fibrillation (VF) or pulseless ventricular tachycardia (pVT). METHODS The inclusion criteria were randomized controlled trials of participants older than eight years old who had atraumatic, out-of-hospital, shock-refractory VF/pVT in which at least one studied group received a medication. We conducted a database search on October 28, 2019, that included PubMed, Scopus, Web of Science, CINAHL Complete, and Cochrane CENTRAL. Citations of relevant meta-analyses were also searched. We performed frequentist network meta-analysis (NMA) to combine the comparisons. The outcomes were analyzed by using odds ratios (OR) and compared to placebo. The primary outcome was survival to hospital discharge. The secondary outcomes included the return of spontaneous circulation (ROSC), survival to hospital admission, and the neurological outcome at discharge. We ranked all outcomes using surface under the cumulative ranking score. RESULTS We included 18 studies with 6,582 participants. The NMA of 20 comparisons included 12 medications and placebo. Only norepinephrine showed a significant increase of ROSC (OR = 8.91, 95% confidence interval [CI], 1.88-42.29). Amiodarone significantly improved survival to hospital admission (OR = 1.53, 95% CI, 1.01-2.32). The ROSC and survival-to-hospital admission data were significantly heterogeneous with the I2 of 55.1% and 59.1%, respectively. This NMA satisfied the assumption of transitivity. CONCLUSION No medication was associated with improved survival to hospital discharge from out-of-hospital, shock-refractory cardiac arrest. For the secondary outcomes, norepinephrine was associated with improved ROSC and amiodarone was associated with an increased likelihood of survival to hospital admission in the NMA.

Abstract
Ventricular fibrillation (VF) and sudden cardiac arrest (SCA) remain some of the most important public health concerns worldwide. For the past 50 years, the recommendation in the Advanced Cardiac Life Support (ACLS) guidelines has been that defibrillation is the only option for shockable cardiac arrest. There is growing evidence to demonstrate that mitochondria play a vital role in the outcome of postresuscitation cardiac function. Although targeting mitochondria to improve resuscitation outcome following cardiac arrest has been proposed for many years, understanding concerning the changes in mitochondria during cardiac arrest, especially in the case of VF, is still limited. In addition, despite new research initiatives and improved medical technology, the overall survival rates of patients with SCA still remain the same. Understanding cardiac mitochondrial alterations during fatal arrhythmias may help to enable the formulation of strategies to improve the outcomes of resuscitation. The attenuation of cardiac mitochondrial dysfunction during VF through pharmacological intervention as well as ischaemic postconditioning could also be a promising target for intervention and inform a new paradigm of treatments. In this review, the existing evidence available from in vitro, ex vivo and in vivo studies regarding the roles of mitochondrial dysfunction during VF is comprehensively summarized and discussed. In addition, the effects of interventions targeting cardiac mitochondria during fatal ventricular arrhythmias are presented. Since there are no clinical reports from studies targeting mitochondria to improve resuscitation outcome available, this review will provide important information to encourage further investigations in a clinical setting.

Abstract
OBJECTIVE To evaluate the impact of the national lockdown because of the 2019 coronavirus (COVID-19) pandemic towards the ED visits and admission rates in Thailand. METHODS We retrospectively reviewed the electronic medical database of patients presenting to the ED during the national lockdown period (from 26 March to 30 June 2020). We used the same time interval in the year 2019 as the control period in our analysis. We collected baseline characteristics and outcomes of each patient in the ED. The primary outcome was the incidence rate ratio (IRR) with a 95% confidence interval (CI) of the average daily ED visits. Secondary outcomes included the IRR with 95% CI of total admissions and intensive care unit (ICU) admissions. RESULTS The average number of daily ED visits decreased significantly from 89.1 to 57.0 (-36.0%, IRR 0.69, 95% CI 0.67-0.70). However, the proportions of 'Resuscitation' and 'Emergency' triage level were increased (29.1% vs 19.2%, P < 0.001). Total ED admission rate and ICU admission rate were also increased (33.5% vs 28.3%, P < 0.001 and 10.2% vs 7.5%, P < 0.001, respectively). The IRR for the admission rate was 1.18 (95% CI 1.11-1.26), and the IRR for the ICU admission rate was 1.35 (95% CI 1.21-1.52). CONCLUSION The national lockdown in Thailand was associated with a significant reduction in average daily ED visits across traumatic and non-traumatic patients. Communication from healthcare professionals and public health officers is necessary to reinforce the importance of timely ED visits for acute health conditions.

Abstract
OBJECTIVES Because the benefits of bicarbonate therapy remain unclear, it is not routinely recommended for the cardiopulmonary resuscitation (CPR) given to individuals with cardiac arrest (CA). This study aims to evaluate the clinical benefits of bicarbonate therapy in adults with CA. METHODS Without any language restriction, we searched PubMed/MEDLINE, Scopus, Web of Science, and Cochrane CENTRAL from the inception until April 30, 2020. We performed hand-search to identify the relevant trials included in previous meta-analyses. Included studies were randomized controlled trials (RCTs) comparing bicarbonate and placebo treatment in adults with CA. Two authors independently assessed the trial risk of bias. The primary outcome was the survival to hospital admission. The secondary outcomes included the return of spontaneous circulation, the survival to hospital discharge, and the neurological outcome at discharge. We calculated the odds ratios of those outcomes using the Mantel-Haenszel model and assessed the heterogeneity using the I2statistic. RESULTS Our searches found 649 unduplicated studies. Of these, three RCTs involving 1344 patients were included in the meta-analysis. The trial risk of bias ranged between fair and poor, mainly due to no blindness of outcome assessment and the selective reports of outcomes. Bicarbonate therapy showed no significant improvement in the survival to hospital admission (odds ratio [OR] 0.96; 95% confidence interval [CI] 0.73-1.25). Subgroup analysis in those receiving prolonged CPR showed a similar result (OR 0.88; 95% CI 0.10-8.01). No study reported the predefined secondary outcomes. CONCLUSION For both acute and prolonged CPR, bicarbonate therapy might not show benefit to improve the rate of survival to hospital admission in adults with cardiac arrest.

Abstract
Objectives: Non-traumatic headache accounts for up to 4.5% of all patients presenting to the emergency department. Non-traumatic headache is generally classified into two categories: primary and secondary headache disorders. Differentiating secondary from primary headache disorders is essential. SNOOP4 is known as a mnemonic for suggesting clinicians send neuroimaging to rule out serious conditions. Yet, the benefit of using this mnemonic in the emergency department is not well established. This study aimed to assess the significance of SNOOP4 in detecting serious causes of non-traumatic headache in adults presenting to the emergency department. Methods: We conducted a prospective observational study of adult patients presenting to the emergency department of the single tertiary hospital over a period of 12 months. Patients with acute non-traumatic headache presented at the emergency department were included. A standard record form was used. Patients were investigated and treated following the pre-existing protocols. Results were interpreted by attending radiologists. Each factor, according to SNOOP4, was then evaluated for the ability to predict serious causes of non-traumatic headache. Results: A total of 90 patients were included in this study with complete details obtained on 83 (92.2%) patients. Of these, 63 (75.9%) were female. The mean age was 44.5 years (inter-quartile range: 27–58.5). The duration of the headache ranged from 10 min to 7 days. Out of 83, 27 (32.5%) had at least one SNOOP4 criterion. In all, 25 patients (30.1%) underwent neuroimaging. The sensitivity, specificity, positive predictive value, and negative predictive value of SNOOP4 were 77.8%, 73.0%, 25.9%, and 96.4% respectively. Conclusion: SNOOP4 criteria show very high negative predictive value for excluding serious causes of acute non-traumatic headache in adult patients presenting to the emergency department.
