RESUMO
STUDY OBJECTIVE: We wished to determine whether the addition of magnesium sulfate (MgSO4) or lidocaine to diclofenac could improve the analgesic efficacy in emergency department (ED) patients with acute renal colic. METHODS: In this prospective, double-blinded, randomized controlled trial of patients aged 18 to 65 years with suspected acute renal colic, we randomized them to receive 75 mg intramuscular (IM) diclofenac and then intravenous (IV) MgSO4, lidocaine, or saline solution control. Subjects reported their pain using a numerical rating scale (NRS) before drug administration and then 5, 10, 20, 30, 60, and 90 minutes afterwards. Our primary outcome was the proportion of participants achieving at least a 50% reduction in the NRS score 30 minutes after drug administration. RESULTS: We enrolled 280 patients in each group. A 50% or greater reduction in the NRS score at 30 minutes occurred in 227 (81.7%) patients in the MgSO4 group, 204 (72.9%) in the lidocaine group, and 201 (71.8%) in the control group, with significant differences between MgSO4 and lidocaine (8.8%, 95% confidence interval [CI] [1.89 to 15.7], P=.013) and between MgSO4 and control (9.9%, 95% CI [2.95 to 16.84], P=.004). Despite this, differences between all groups at every time point were below the accepted 1.3 threshold for clinical importance. There were no observed differences between groups in the frequency of rescue analgesics and return visits to the ED for renal colic. There were more adverse events, although minor, in the MgSO4 group. CONCLUSION: Adding intravenous MgSO4, but not lidocaine, to IM diclofenac offered superior pain relief but at levels below accepted thresholds for clinical importance.
RESUMO
BACKGROUND: Zinc supplementation has been considered a potential therapy for coronavirus disease 2019 (COVID-19). We aimed to examine zinc efficacy in adult patients with COVID-19 infection. METHODS: We conducted a prospective, randomized, double-blind, placebo-controlled multicenter trial. Patients who were tested positive for COVID-19 without end-organ failure were randomized to oral zinc (n = 231) or matching placebo (n = 239) for 15 days. The primary combined outcome was death due to COVID-19 or intensive care unit (ICU) admission ≤30 days after randomization. Secondary outcomes included length of hospital stay for inpatients and duration of COVID-19 symptoms with COVID-19-related hospitalization for outpatients. RESULTS: 190 patients (40.4%) were ambulatory and 280 patients (59.6%) were hospitalized. Mortality at 30 days was 6.5% in the zinc group and 9.2% in the placebo group (OR: .68; 95% CI .34-1.35); ICU admission rates were, respectively, 5.2% and 11.3% (OR: .43; 95% CI .21-.87). Combined outcome was lower in the zinc group versus the placebo group (OR: .58; 95% CI .33-.99). Consistent results were observed in prespecified subgroups of patients aged <65 years, those with comorbidity, and those who needed oxygen therapy at baseline. Length of hospital stay was shorter in the zinc group versus the placebo group (difference: 3.5 days; 95% CI 2.76-4.23) in the inpatient group; duration of COVID-19 symptoms decreased with zinc treatment versus placebo in outpatients (difference: 1.9 days; 95% CI .62-2.6). No severe adverse events were observed during the study. CONCLUSIONS: Our results showed that, in COVID-19 patients, oral zinc can decrease 30-day death, ICU admission rate and can shorten symptom duration. Clinical Trials Registration.

BACKGROUND: Left heart failure (LHF) is commonly associated with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) but its role is often underestimated. AIM OF STUDY: To evaluate the performance of a new diagnostic technique based on the measurement of the pulse amplitude ratio (PAR) using non-invasive ventilation (NIV) for the early identification LHF in patients admitted to the emergency department (ED) for AECOPD. RESULTS: 73 patients were included in this study: 32 in LHF group and 41 in non LHF- group. The two groups had comparable demographic and clinical characteristics at admission. The mean values of PARNIV was significantly higher among LHF patients (0.86 vs. 0.71; p < 0.01). The area under the receiver operating characteristic curve of PARNIV was 0.75. Using the best cut-off (0.6), the sensitivity of PARNIV was 93% with a specificity 21%, a positive predictive value of 48%, and a negative predictive value of 81%. Correlation between PARNIV and BNP was significant (r = 0.52; p = 0.002). CONCLUSION: Measurement of PARNIV in patients presenting to the ED with AECOPD had a good diagnostic performance for the detection of LHF and could represent an interesting alternative for the currently available methods. Trial registration The study was registered in the Clinical Trial Registration System (clinicaltrials.gov) under the study number NCT05189119, https://register.

INTRODUCTION: Inferior vena cava (IVC) diameter variability with respiration measured by ultrasound was found to be useful for the diagnosis of heart failure (HF) in ED patients with acute dyspnea. Its value in identifying HF in acute exacerbation of chronic obstructive pulmonary disease exacerbation (AECOPD) was not specifically demonstrated. OBJECTIVE: To determine the value of ΔIVC in the diagnosis of HF patients with AECOPD. METHODS: This is a prospective study conducted in the ED of three Tunisian university hospitals including patients with AECOPD. During this period, 401 patients met the inclusion criteria. The final diagnosis of HF is based on the opinion of two emergency experts after consulting the data from clinical examination, cardiac echocardiography, and BNP level. The ΔIVC was calculated by two experienced emergency physicians who were blinded from the patient's clinical and laboratory data. A cut off of 15% was used to define the presence (< 15%) or absence of HF (≥ 15%). Left ventricular ejection fraction (LVEF) was also measured. The area under the ROC curve, sensitivity, specificity, and positive and negative predictive values were calculated to determine the diagnostic and predictive accuracy of the ΔIVC in predicting HF. RESULTS: The study population included 401 patients with AECOPD, mean age 67.2 years with male (68.9%) predominance. HF was diagnosed in 165 (41.1%) patients (HF group) and in 236 patients (58.9%) HF was excluded (non HF group). The assessment of the performance of the ΔIVC in the diagnosis of HF showed a sensitivity of 37.4% and a specificity of 89.7% using the threshold of 15%. The positive predictive value was 70.9% and the negative predictive value was 66.7%. The area under the ROC curve was 0.71(95%, CI 0.65-0.76). ΔIVC values were not different between HF patients with reduced LVEF and those with preserved LVEF. CONCLUSION: Our results showed that ΔIVC has a good value for ruling out HF in ED patients consulting for AECOPD.

BACKGROUND: Emergency medicine is particularly well suited to simulation training. However, evidence for the efficacy of simulation-based medical training remains limited especially to manage high-risk cases such as acute asthma. OBJECTIVE: The objective of our study was to compare the performance of high-fidelity simulation (HFS) and interactive video-case challenge-based training (IVC) for final-year medical students in the management of acute asthma. METHODS: This was a prospective randomized controlled study conducted at the emergency department (ED) of Monastir University hospital ( Tunisia). 69 final-year medical students were randomized to HFS (n = 34) and IVC (n = 35) training on acute asthma topic. The study was conducted over a 1-week period. Efficacy of each teaching method was compared through the use of multiple-choice questionnaires (MCQ) before (pre-test), after (post-test) training and a simulation scenario test conducted 1 week later. The scenario was based on acute asthma management graded on predefined critical actions using two scores: the checklist clinical score (range 0 to 30), and the team skills score (range 0 to 16). Student satisfaction was also evaluated with the Likert 5 points scale. Two years after the post-test, both groups underwent a third MCQ testing to assess sustainability of knowledge. RESULTS: There were no differences in age between groups. There was no statistically significant difference between the HFS and IVC groups pre-test scores (p = 0.07). Both groups demonstrated improvement in MCQ post-test from baseline after training session; the HFS MCQ post-test score increased significantly more than the IVC score (p < 0.001). The HFS group performed better than the IVC group on the acute asthma simulation scenario (p < 0.001). Mean checklist clinical score and mean team skills score were significantly higher in HFS group compared to IVC group (respectively 22.9 ± 4.8 and 11.5 ± 2.5 in HFS group vs 19.1 ± 3 and 8.4 ± 3.1 in IVC group) (p < 0.001). After 2 years, MCQ post-test scores decreased in both groups but the decrease was lower in HFS group compared to the IVC group. CONCLUSION: High-fidelity simulation-based training was superior to interactive video-case challenge for teaching final year medical students,and led to more long-term knowledge retention in the management of simulated acute asthma patients. TRIAL REGISTRATION: The study was registered at www. CLINICALTRIALS: gov NCT02776358 on 18/05/2016.

BACKGROUND: Chest pain remains one of the most challenging serious complaints in the emergency department (ED). A prompt and accurate risk stratification tool for chest pain patients is paramount to help physcian effectively progrnosticate outcomes. HEART score is considered one of the best scores for chest pain risk stratification. However, most validation studies of HEART score were not performed in populations different from those included in the original one. OBJECTIVE: To validate HEART score as a prognostication tool, among Tunisian ED patients with undifferentiated chest pain. METHODS: Our prospective, multicenter study enrolled adult patients presenting with chest pain at chest pain units. Patients over 30 years of age with a primary complaint of chest pain were enrolled. HEART score was calculated for every patient. The primary outcome was major cardiovascular events (MACE) occurrence, including all-cause mortality, non-fatal myocardial infarction (MI), and coronary revascularisation over 30 days following the ED visit. The discriminative power of HEART score was evaluated by the area under the ROC curve. A calibration analysis of the HEART score in this population was performed using Hosmer-Lemeshow goodness of test. RESULTS: We enrolled 3880 patients (age 56.3; 59.5% males). The application of HEART score showed that most patients were in intermediate risk category (55.3%). Within 30 days of ED visit, MACE were reported in 628 (16.2%) patients, with an incidence of 1.2% in the low risk group, 10.8% in the intermediate risk group and 62.4% in the high risk group. The area under receiver operating characteristic curve was 0.87 (95% CI 0.85-0.88). HEART score was not well calibrated (χ2 statistic = 12.34; p = 0.03). CONCLUSION: HEART score showed a good discrimination performance in predicting MACE occurrence at 30 days for Tunisian patients with undifferentiated acute chest pain. Heart score was not well calibrated in our population.

AIM OF THE STUDY: The diagnosis of heart failure in the emergency department (ED) is challenging. The aim of this study was to evaluate systolic time intervals (STIs) using phonoelectrocardiography for the diagnosis of heart failure (HF) in ED patients with undifferentiated dyspnea. METHODS: A total of 855 patients with dyspnea and suspected HF were prospectively enrolled. They underwent echocardiographic measurements of left ventricular ejection fraction (LVEF), B-type natriuretic peptide (BNP) testing and computerised phonoelectrocardiography to assess STIs including electromechanical activation time (EMAT), left ventricular ejection time (LVET) and EMAT/LVET ratio. Diagnosis accuracy of STIs was calculated including sensitivity, specificity, likelihood ratio and receiver operating characteristic (ROC) curve. RESULTS: Patients with HF (n = 530) had significantly higher EMAT and lower LVET compared with non-HF patients. ROC curve c-statistic was 0.74, 0.72 and 0.78 for EMAT, LVET and EMAT/LVET respectively. Sensitivity and specificity of EMAT/LVET at a cut-off = 40% were 72% and 88% respectively. EMAT/LVET had the highest correlation with LVEF (r = 0.48). In patients with intermediate BNP (n = 107), positive likelihood ratio increased from 1.8 with BNP alone to 3.6 with BNP combined to EMAT/LVET. Patients without HF had STIs values not significantly different from those with preserved LVEF (≥45%). CONCLUSIONS: Given their immediate availability, phonoelectrocardiography STIs' parameters and particularly EMAT/LVET ratio could have an important role in the diagnosis approach of HF in patients with undifferentiated dyspnea in the ED.

OBJECTIVES: To evaluate the effect on opioid requirement of pain treatment starting at triage, and to evaluate satisfaction in emergency department (ED) patients with acute pain. METHODS: This is a single-blind, randomized, prospective study conducted in the ED. The included patients were randomly assigned to single oral doses of placebo, acetaminophen, or a tramadol/acetaminophen combination. Protocol treatment was given at triage. The primary outcome was the need for rescue morphine during ED stay. The secondary outcome included patient satisfaction, ED length of stay, and percentage of patients discharged from the ED with a VAS score of <30. RESULTS: We included 1,485 patients: 496 patients in the placebo group, 497 in the acetaminophen group, and 492 in the tramadol/acetaminophen combination group. The groups were similar regarding demographic and clinical characteristics and baseline VAS pain scores. Rescue morphine was significantly decreased in the tramadol/acetaminophen combination group compared to that in the placebo and acetaminophen groups (11.5%, 23.2%, and 18.9%, respectively; P = 0.03). Patient satisfaction was higher in the tramadol/acetaminophen combination group (77% vs. 69% in the acetaminophen group and 68% in the placebo group). A VAS score of <30 was observed in 84% of patients in the placebo group, 83% in the acetaminophen group, and 87% in the tramadol/acetaminophen combination group (P = 0.01 between the acetaminophen group and tramadol/acetaminophen combination group). The ED length of stay was 60 minutes for the acetaminophen group and tramadol/acetaminophen combination group and 71 minutes for the placebo group (P = 0.04). CONCLUSION: Oral tramadol/acetaminophen combination administered early in triage was associated with a decrease in intravenous morphine requirement and increase in satisfaction among ED patients with acute pain when compared with patients taking acetaminophen. No significant increase in side effects was found. This intervention may be considered in EDs with an aim of similar benefits.

BACKGROUND: The aim of this study is to test the diagnostic value of baseline and early change of C-reactive protein (CRP) concentrations, evaluated separately or in combination with the modified Alvarado score (MAS), in patients with clinically suspected acute appendicitis. METHODS: This is a prospective observational study including all patients presenting to the emergency department with an equivocal diagnosis of acute appendicitis. After inclusion, clinical and demographic data are recorded and blood samples were taken at baseline and 3 h after for serum CRP measurements (3 h CRP). The MAS is also calculated for all patients. The ultimate diagnosis of appendicitis was based on the histologic findings of the excised appendix in operated patients and clinical follow-up in emergency department discharged patients. Diagnostic accuracy of admission CRP, early change of CRP 3 h CRP minus admission CRP, MAS and the combination of these parameters was expressed by sensitivity, specificity, positive predictive value, negative predictive value and area under receiver operating characteristics curve. RESULTS: Five hundred patients were included from January 2010 to December 2013. Overall, 387 patients were operated the negative appendectomy rate was 8,3%. CRP concentrations were higher in patients with acute appendicitis. However, the diagnostic value of admission CRP, delta CRP and MAS was moderate with area under ROC curve respectively equal to 0.63, 0.53 and 0.6. Combining admission CRP and delta CRP values to MAS did not result in a better performance. The area under ROC curve did not exceed 0.7 with the different combinations. CONCLUSION: Early change of CRP has a moderate diagnostic value in patients with clinically suspected acute appendicitis. Combining CRP values to MAS did not improve diagnostic accuracy.

BACKGROUND: We aimed to describe diagnosed acute coronary syndrome (ACS) and its care management and outcomes in emergency departments (EDs) and to determine related cardiovascular risk factors (CVRFs). METHODS: We conducted a cross sectional multicenter study that included 1173 adults admitted to EDs for acute chest pain (ACP) in 2015 at 14 sites in Tunisia. Data included patients' baseline characteristics, diagnosis, treatment and output. RESULTS: ACS represented 49.7% of non-traumatic chest pain [95% CI: 46.7-52.6]; 74.2% of ACS cases were unstable angina/non-ST-segment-elevation myocardial infarction (UA/NSTEMI). Males represented 67.4% of patients with ACS (p < 0.001). The median age was 60 years (IQR 52-70). Emergency medical service transportation was used in 11.9% of cases. The median duration between chest pain onset and ED arrival was two hours (Inter quartile ranges (IQR) 2-4 h). The age-standardized prevalence rate was 69.9/100,000 PY; the rate was 96.24 in men and 43.7 in women. In the multivariable analysis, CVRFs related to ST segment elevation myocardial infarction were age correlated to sex and active smoking. CVRFs related to UA/NSTEMI were age correlated to sex, familial and personal vascular history and type 2 diabetes. We reported 27 cases of major adverse cardiovascular events (20.0%) in patients with STEMI and 36 in patients with UA/NSTEMI (9.1%). CONCLUSION: Half of the patients consulting EDs with ACP had ACS. Emergency medical service transportation calls were rare. Management delays were acceptable. The risk of developing an UA/NSTEMI was equal to the number of CVRFs + 1. To improve patient outcomes, it is necessary to increase adherence to international management guidelines.

BACKGROUND: Acupuncture is one of the oldest techniques to treat pain and is commonly used for a large number of indications. However, there is no sufficient evidence to support its application in acute medical settings. METHODS: This was a prospective, randomized trial of acupuncture vs morphine to treat ED patients with acute onset moderate to severe pain. Primary outcome consists of the degree of pain relief with significant pain reduction defined as a pain score reduction ≥50% of its initial value. We also analyzed the pain reduction time and the occurrence of short-term adverse effects. We included in the protocol 300 patients with acute pain: 150 in each group. RESULTS: Success rate was significantly different between the 2 groups (92% in the acupuncture group vs 78% in the morphine group P<.001). Resolution time was 16±8 minutes in the acupuncture group vs 28±14 minutes in the morphine group (P<.005). Overall, 89 patients (29.6%) experienced minor adverse effects: 85 (56.6%) in morphine group and 4 (2.6%) in acupuncture group (P<.001). No major adverse effects were recorded during the study protocol. In patients with acute pain presenting to the ED, acupuncture was associated with more effective and faster analgesia with better tolerance. CONCLUSION: This article provides an update on one of the oldest pain relief techniques (acupuncture) that could find a central place in the management of acute care settings. This should be considered especially in today's increasingly complicated and polymedicated patients to avoid adverse drug reactions.

BACKGROUND: Few studies have identified the willingness rate of developing countries population to be enrolled in clinical trials. METHODS: All participants including patients (n = 612), healthy volunteers (n = 354) and doctors (n = 134) completed a questionnaire to examine factors affecting the consent to participate in medical research. RESULTS: Overall, 80 % of the included population agree to participate in health research. This rate was lower for trials dealing with life-threatening diseases (38 %). Altruism and perceived risk of harm were the main reason to respectively accept or refuse to participate in clinical trials. Factors significantly associated with willingness were: age <40 years (Odds Ratio (OR) 1.6 [95 % Confidence Interval (CI) 1.2-2.1]) and prior history of blood donation (OR 2.4 [95 % CI 1.7-3.5]). CONCLUSION: Most participants expressed their willingness to be included in medical research especially if they are young or if they have history of blood donation. However, consent to participate is low when medical research required acute care.

BACKGROUND: Data on the effect of fasting on coronary disease are rare and controversial. The aim of our study was to investigate the influence of Ramadan on the prevalence of acute coronary syndrome among chest pain patients in the emergency department of Monastir. METHODS: It was a prospective study, performed in the emergency department of Fattouma Bourguiba University Hospital of Monastir, during the 3 months before, during and after Ramadan from 2012 to 2014. We included all patients with non-traumatic chest pain during the study period. Data were collected using a standardized form. The uniformity chi 2 test, ANOVA test, Kruskal-Wallis test were performed at the 5% level. Binary logistic regression model was used for multivariate analysis. RESULTS: The SCA prevalence was 17% a month before Ramadan, 22% during Ramadan and 28% one month after Ramadan (p = 0.007). According to the results of the multivariate analysis, the period of Ramadan is not associated with increase of risk of SCA whereas the risk doubles after Ramadan in all group (p = 0.001). In subgroups analysis, the period of R was associated with an amplification of risk in men aged more than 55 years and women older than 65 years (OR: 2.1; p = 0.020) and among subjects with hypertension (OR: 2.4, p = 0.007). Ramadan and Shawwal were not associated with an increase of risk among subjects without CVX risk factor. CONCLUSION: We have demonstrated that the risk of SCA has increased in Ramadan only among the elderly and patient with hypertension. The increased risk in Shawwal can be explained by the lifting of dietary restriction.

BACKGROUND: Our aim was to compare the efficacy and safety of intravenous (IV) titrated morphine with nebulized morphine given at 2 different doses in severe traumatic pain. METHODS: In a prospective, randomized, controlled double-blind study, we included 300 patients with severe traumatic pain. They were assigned to 3 groups: Neb10 group received 1 nebulization of 10-mg morphine; Neb20 group received 1 nebulization of 20-mg morphine, repeated every 10 minutes with a maximum of 3 nebulizations; and the IV morphine group received 2-mg IV morphine repeated every 5 minutes until pain relief. Visual analog scale was monitored at baseline, 5, 10, 15, 20, 25, 30, and 60 minutes after the start of drug administration. Treatment success was defined by the percentage of patients in whom visual analog scale decreased greater than or equal to 50% of its baseline value. When this end point was not reached, rescue morphine was administered. Pain resolution time was defined by the elapsed time between the start of the protocol and the reach of treatment success criteria. RESULTS: Success rate was significantly better at 97% (95% confidence interval [CI], 93-100) for Neb20 group compared to Neb10 group (81% [95% CI, 73-89]) and IV morphine group (79% [95% CI, 67-84]). The lowest resolution time was observed in Neb20 group (20 minutes [95% CI, 18-21]). Side effects were minor and significantly lower in both nebulization groups compared to IV morphine group. CONCLUSIONS: Nebulized morphine using boluses of 10 mg has similar efficacy and better safety than IV titrated morphine in patients with severe posttraumatic pain. Increasing nebulized boluses to 20 mg increases the effectiveness without increasing side effects.

PURPOSE: The Thrombolysis in Myocardial Infarction (TIMI) and the Global Registry in Acute Coronary Events (GRACE) scores were largely evaluated and validated in stratifying risk of cardiovascular events in patients with chest pain and acute coronary syndrome. Our objective was to compare these 2 scores in predicting outcome in emergency department (ED) patients with undifferentiated chest pain. MATERIALS AND METHODS: This was a prospective cohort study including patients presenting to 4 EDs with chest pain with nondiagnostic or normal ECG. For all included patients (n = 3125), TIMI and GRACE scores were calculated. Follow-up was conducted at 30-day and 1-year post-ED index admission to identify major adverse events. Main outcome included all cause mortality, acute coronary syndrome, and coronary non-ED planned revascularization. Prognostic performance of the scores was assessed by the receiver operating characteristic (ROC) curves. RESULTS: We reported 285 (9.1%) major adverse events at 30 days and 436 (13.9%) at 1 year. In patients with low TIMI (≤2) and GRACE (<109) scores, a significant proportion had major adverse events at 30 days (5% and 7.5%, respectively) and 1 year (7.9% and 12.9%, respectively). Area under ROC curve at 30 days was 0.66 (95% confidence interval [CI], 0.62-0.71) vs 0.57 (95% CI, 0.53-0.62), respectively, for TIMI and GRACE scores. At 1 year, the area under ROC was 0.67 (95% CI, 0.62-0.71) and 0.65 (95% CI, 0.60-0.70), respectively, for TIMI and GRACE scores. CONCLUSIONS: The TIMI and GRACE scores are not valid in short- and long-term risk stratification in our chest pain patients.

BACKGROUND: Acute coronary syndrome (ACS) represents a difficult diagnostic challenge in patients with undifferentiated chest pain. There is a need for a valid clinical score to improve diagnostic accuracy. OBJECTIVES: To compare the performance of a model combining the Thrombolysis in Myocardial Infarction (TIMI) score and a score describing chest pain (ACS diagnostic score: ACSD score) with that of both scores alone in the diagnosis of ACS in ED patients with chest pain associated with a non-diagnostic ECG and normal troponin. METHODS: In this observational cohort study, we enrolled 809 patients admitted to a chest pain unit with normal ECG and normal troponin. They were prospectively evaluated in order to calculate TIMI score, chest pain characteristics score and ACSD score. Diagnosis of ACS was the primary outcome and defined on the basis of 2 cardiologists after reviewing the patient medical records and follow-up data. Mortality and major cardiovascular events were followed for 1 month for patients discharged directly from ED. Discriminative power of scores was evaluated by the area under the ROC curve. RESULTS: ACS was confirmed in 90 patients (11.1%). The area under the ROC curve for ACSD score was 0.85 (95% CI 0.80 to 0.90) compared with 0.74 (95% CI 0.67 to 0.81) for TIMI and 0.79 (95% CI 0.74 to 0.84) for chest pain characteristics score. A threshold value of 9 appeared to optimise sensitivity (92%) and negative predictive value (99%) without excessively compromising specificity (62%) and positive predictive value (23%). CONCLUSIONS: The ACSD score showed a good discrimination performance and an excellent negative predictive value which allows safely ruling out ACS in ED patients with undifferentiated chest pain. Our findings should be validated in a larger multicentre study.

Treatment with short-acting ß2-agonists for exacerbations of chronic obstructive pulmonary disease (COPD) results in clinical improvement. It has not been established whether combining short-acting ß2-agonists to other bronchodilators is more effective than ß2-agonists alone. We conducted a study in patients presenting to the emergency department with exacerbation of COPD. They were randomized to receive nebulized ipratropium bromide (IB group; n = 62) or combined nebulized and intravenous bolus of magnesium sulfate (MgSO4 group; n = 62). All nebulized drugs were administered at 30-minute intervals for 2 hours. Primary outcome included hospital admission, endotracheal intubation, and hospital death rates. Secondary outcome measures were improvement in peak expiratory flow, dyspnea score, and arterial blood gas changes within the first 3 hours. There were no significant differences in primary outcome between MgSO4 and IB groups. Patients given IB average 32 L greater improvement in peak expiratory flow rate compared with magnesium sulfate (95% confidence interval, 19-43 L) at 180 minutes. Simultaneously, there was a significant reduction in PaCO2 compared with baseline values in IB group but not in MgSO4 group. There was a statistically nonsignificant trend toward a decrease in dyspnea score in both groups although adverse events were similar. Although the improvement in peak expiratory flow rate and arterial blood gas favored nebulized IB over magnesium sulfate, there was a nonsignificant difference between both drugs with regard to hospital admission, intubation, and hospital death rates in patients with COPD treated in the emergency department for acute exacerbation.

Introduction: Identifying heart failure (HF) in acute exacerbation of chronic obstructive pulmonary disease (AECOPD) can be challenging. Lung ultrasound sonography (LUS) B-lines quantification has recently gained a large place in the diagnosis of HF, but its diagnostic performance in AECOPD remains poorly studied. Purpose: This study aimed to assess the contribution of LUS B-lines score (LUS score) in the diagnosis of HF in AECOPD patients. Patients and methods: This is a prospective cross-sectional multicenter cohort study including patients admitted to the emergency department for AECOPD. All included patients underwent LUS. A lung ultrasound score (LUS score) based on B-lines calculation was assessed. A cardiac origin of dyspnea was retained for a LUS score greater than 15. HF diagnosis was based on clinical examination, pro-brain natriuretic peptide levels, and echocardiographic findings. The LUS score diagnostic performance was assessed by receiver operating characteristic (ROC) curve, sensitivity, specificity, and likelihood ratio at the best cutoffs. Results: We included 380 patients, mean age was 68±11.6 years, sex ratio (M/F) 1.96. Patients were divided into two groups: the HF group [n=157 (41.4%)] and the non-HF group [n=223 (58.6%)]. Mean LUS score was higher in the HF group (26.8±8.4 vs 15.3±7.1; p<0.001). The mean LUS score in the HF patients with reduced LVEF was 29.2±8.7, and was 24.5±7.6 in the HF patients with preserved LVEF. LUS score area under ROC curve for the diagnosis of HF was 0.71 [0.65-0.76]. The best sensitivity (89% [85.9-92,1]) was observed at the threshold of 5; the best specificity (85% [81.4-88.6]) was observed at the threshold of 30. Correlation between LUS score and E/E' ratio was good (R=0.46, p=0.0001). Conclusion: Our results suggest that LUS score could be helpful and should be considered in the diagnostic approach of HF in AECOPD patients, at least as a ruling in test.

OBJECTIVE: Renal colic (RC) is a common urologic emergency often leading to significant pain and recurrent hospital visits. This study aimed to compare the efficacy and safety of piroxicam versus paracetamol in preventing pain recurrence and hospital readmission in patients treated for RC and discharged from the emergency department (ED). METHODS: A prospective, randomized, single-blind trial was conducted in four EDs. Eligible adults with RC were randomized to receive oral piroxicam, paracetamol, or placebo for 5 days post-ED discharge. Primary outcomes included pain recurrence and ED readmission within 7 days. Secondary outcomes included time to recurrence and treatment-related side effects. RESULTS: Of 1383 enrolled patients, no significant differences were observed among the groups regarding baseline characteristics. Pain recurrence rates within 7 days were 29% (95% confidence interval [CI] 24.9%-33.2%) for piroxicam, 30.3% (95% CI 26.1%-34.5%) for paracetamol, and 30.8% (95% CI 26.6%-35.0%) for placebo, with no significant between-group differences (p = 0.84). Among patients experiencing recurrence, the majority encounter it within the initial 2 days following their discharge (86% in the piroxicam group, 84.1% in the paracetamol group, and 86% in the placebo group, respectively). ED readmission rates were similar across groups: 20.8% (95% CI 17.1%-24.5%) in the piroxicam group, 23.8% (95% CI 19.9%-27.7%) in the paracetamol group, and 22.9% (95% CI 19.1%-26.8%) in the placebo group (p = 0.52). The piroxicam group reported significantly higher adverse effects compared to others. CONCLUSIONS: Piroxicam and paracetamol did not demonstrate efficacy in preventing pain recurrence or ED readmission within the first week following RC treatment.
