Comparison of the Predictive Ability of the Blood Urea Nitrogen/Albumin, C-Reactive Protein/Albumin, and Lactate/Albumin Ratios for Short-Term Mortality in SARS-CoV-2-Infected Patients.

Background Hematological parameters and their ratios are the most studied biomarkers for prediction of mortality or severe illness in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. This study aims to compare the power of the blood urea nitrogen (BUN)/albumin ratio, lactate/albumin ratio, and C-reactive protein (CRP)/albumin ratio, measured at the time of admission, in predicting 30-day mortality in SARS-CoV-2-infected patients presenting to the emergency department (ED). Materials and Methods This retrospectively designed, single-center, observational study was performed in the ED of a tertiary education health care center. We documented the data of patients admitted with a confirmed SARS-CoV-2 infection between September 1, 2020, and January 1, 2021. Results Of the 470 patients included in the study, 232 (49.4%) were female. The all-cause 30-day mortality rate was 23.8%. The area under the curve values for the BUN/albumin ratio, lactate/albumin ratio, and CRP/albumin ratio in the prediction of 30-day mortality were 0.725, 0.641, and 0.749, respectively. Sensitivity and negative predictive value for CRP/albumin ratio (≥0.049) and specificity for BUN/albumin ratio (≥1.17) were 92.86, 94.9, and 71.23, respectively. The odds ratio values of the BUN/albumin ratio (≥1.17), CRP/albumin ratio (≥0.049), and lactate/albumin ratio (≥0.046) for 30-day mortality were determined as 4.886, 9.268, and 2.518, respectively. Conclusion The BUN/albumin ratio and CRP/albumin ratio can be used to predict 30-day mortality in SARS-CoV-2-infected patients admitted to ED. Furthermore, CRP/albumin ratio had the highest sensitivity and negative predictive value, while BUN/albumin ratio had the highest specificity.

Diagnostic Value of Lateral Ankle Radiography in Achilles Tendon Rupture.

INTRODUCTION: Achilles tendon rupture (ATR) is a common sports injury, but approximately 20% of acute ATR cases are misdiagnosed as ankle sprains at first presentation. This study aimed to investigate the diagnostic value of lateral ankle radiography in the diagnosis of acute ATR. METHODS: This was a retrospective case-control study in which the lateral ankle radiographs of patients who presented to the emergency department between January 1, 2015 and December 31, 2019 were examined. The study included a total of 154 patients with acute ATR, who underwent lateral ankle radiography at the presentation and were surgically or magnetic resonance imaging (MRI) confirmed to have ATR in our hospital. The lateral ankle radiographs of the patients were examined by 2 clinicians blinded to clinical data for the following 3 findings: Kager's fat pad sign, tibio-first metatarsal angle, and tibiocalcaneal angle. The same procedure was repeated for 308 controls who underwent lateral ankle radiography and were diagnosed with ankle sprain. RESULTS: Kager's fat pad sign was detected in 133 (86.4%) of the 154 patients with ATR and 26 (8.4%) of the 308 patients in the control group. The Kager's fat pad sign, tibio-first metatarsal angle, and tibiocalcaneal angle sensitivity values for the diagnosis of ATR were 86.4%, 61.7%, and 65.6%, respectively, and their specificity values were 91.6%, 78.9%, and 56.2%, respectively. Interobserver reliability was determined to be good for all 3 radiographic findings. CONCLUSION: Clinicians should be particularly aware of Kager's fat pad sign when examining lateral ankle radiographs for ankle injury. LEVELS OF EVIDENCE: Level IV: Case control study.

Effect of the COVID-19 Pandemic on Emergency Department Presentations with Mushroom Poisoning: A Report from Turkey.

Background In this study, we investigated the effect of the coronavirus disease 2019 (COVID-19) pandemic on emergency department admissions with mushroom poisoning in a tertiary hospital in Turkey. Materials and Methods This study was conducted as a retrospective cohort study to evaluate the data of patients admitted to the emergency department between January 1, 2018, and December 31, 2020. The patients diagnosed with the International Classification of Diseases-10 code T62.0 concerning the toxic effect of ingested mushrooms were identified through the computerized medical and laboratory record system of the hospital. The patients' demographic data, presentation seasons, laboratory findings, emergency department outcomes, and mortality due to mushroom poisoning were obtained. To reveal the effect of COVID-19 pandemic on emergency department presentations with mushroom poisoning, the means of the pre-pandemic period (2018-2019) and the pandemic period (2020) were compared. Results The data of a total of 171 patients were included in the final analysis. The number of patients diagnosed with the toxic effect of ingested mushrooms was 96 in 2018, 61 in 2019, and 14 in 2020. There was a 5.6-fold decrease during pandemic period in the number of patients presenting to the emergency department with mushroom poisoning. Conclusion The decrease in mushroom poisoning cases may be related to the changes in the eating habits of individuals during the pandemic and our study being conducted in a metropolitan city. We recommend that multicenter studies be performed to verify the data obtained from our study and increase their generalizability.

The role of a noninvasive index 'Spo2/ Fio2' in predicting mortality among patients with COVID-19 pneumonia.

INTRODUCTION: Noninvasive risk assessment is crucial in patients with COVID-19 in emergency department. Since limited data is known about the role of noninvasive parameters, we aimed to evaluate the role of a noninvasive parameter 'SpO2/FiO2' in independently predicting 30-day mortality in patients with COVID-19 and its prognostic utility in combination with a noninvasive score 'CRB-65'. METHODS: A retrospective study was performed in a tertiary training and research hospital, which included 272 patients with COVID-19 pneumonia diagnosed with polymerase chain reaction in emergency department. Data on characteristics, vital signs, and laboratory parameters were recorded from electronic medical records. The primary outcome of the study was 30-day mortality, and we assessed the discriminative ability of SpO2/FiO2 in predicting mortality in patients with COVID-19 pneumonia and its prognostic utility in combination with conventional pneumonia risk assessment scores. RESULTS: Multivariate analysis revealed that only SpO2/FiO2 level was found to be an independent parameter associated with 30-day mortality (OR:0.98, 95% CI: 0.98-0.99, p = 0.003). PSI and CURB-65 were found to be better scores than CRB-65 in predicting 30-day mortality (AUC: 0.79 vs 0.72, p = 0.04; AUC: 0.76 vs 0.72, p = 0.01 respectively). Both SpO2/FiO2 combined with CRB-65 and SpO2/FiO2 combined with CURB-65 have good discriminative ability and seemed to be more favorable than PSI in predicting 30-days mortality (AUC: 0.83 vs 0.75; AUC: 0.84 vs 0.75), however no significant difference was found (p = 0.21 and p = 0.06, respectively). CONCLUSION: SpO2/FiO2 is a promising index in predicting mortality. Addition of SpO2/FiO2 to CRB-65 improved the role of CRB-65 alone, however it performed similar to PSI. The combined noninvasive model of SpO2/FiO2 and CRB-65 may help physicians quickly stratify COVID-19 patients on admission, which is expected to be particularly important in hospitals still stressed by pandemic volumes.

Predictive Ability of the MEWS, REMS, and RAPS in Geriatric Patients With SARS-CoV-2 Infection in the Emergency Department.

BACKGROUND: The aim of this study was to compare the ability of the Modified Early Warning Score (MEWS), Rapid Emergency Medicine Score (REMS), and Rapid Acute Physiology Score (RAPS) to predict 30-d mortality in patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection aged 65 y and over. METHODS: This prospective, single-center, observational study was carried out with 122 volunteers aged 65 y and over with patients confirmed to have SARS-CoV-2 infection according to the reverse transcriptase-polymerase chain reaction (RT-PCR) test, who presented to the emergency department between March 1, 2020, and May 1, 2020. Demographic data, comorbidities, vital parameters, hematological parameters, and MEWS, REMS, and RAPS values of the patients were recorded prospectively. RESULTS: Among the 122 patients included in the study, the median age was 71 (25th-75th quartile: 67-79) y. The rate of 30-d mortality was 10.7% for the study cohort. The area under the receiver operating characteristic curve values for MEWS, RAPS, and REMS were 0.512 (95% confidence interval [CI]: 0.420-0.604; P = 0.910), 0.500 (95% CI: 0.408-0.592; P = 0.996), and 0.675 (95% CI: 0.585-0.757; P = 0.014), respectively. The odds ratios of MEWS (≥2), RAPS (>2), and REMS (>5) for 30-d mortality were 0.374 (95% CI: 0.089-1.568; P = 0.179), 1.696 (95% CI: 0.090-31.815; P = 0.724), and 1.008 (95% CI: 0.257-3.948; P = 0.991), respectively. CONCLUSIONS: REMS, RAPS, and MEWS do not seem to be useful in predicting 30-d mortality in geriatric patients with SARS-CoV-2 infection presenting to the emergency department.

Diagnostic performance of thorax CT in mildly symptomatic COVID-19 patients: The importance of atypical CT findings.

OBJECTIVE: Computed tomography of the thorax (Thorax CT) is frequently used to diagnose viral pneumonia in moderate to severe COVID-19 patients, but its diagnostic performance in mildly symptomatic COVID-19 patients is still unclear. Assessing the diagnostic performance of thorax CT in mildly symptomatic COVID-19 patients was the purpose of our study. METHODS: Mildly symptomatic and clinically stable, suspected COVID-19 patients scanned with Thorax CTs between March 11, 2020, and April 13, 2020, were included in this study. The sensitivity, specificity, positive and negative likelihood ratios, positive and negative predictive values, and the respective accuracies were calculated for diagnostic purposes. RESULTS: Among the 1119 patients enrolled in our study, abnormal thorax CT scans were 527 out of which 363/527 (68.9%) had typical CT features for COVID-19. According to analysis of typical COVID findings, sensitivity, specificity, positive predictive values, negative predictive value, and the accuracy of Thorax CTs with were 51.45%, 86.07%, 78.24%, 64.55%, and 68.99%, respectively. When typical CT findings and atypical CT findings were combined for the statistical analysis, the sensitivity, specificity, and accuracy observed 68.84%, 74%, and 71.49%. CONCLUSION: Diagnosing pneumonia can be challenging in mildly symptomatic COVID-19 patients since the Reverse Transcription Polymerase Chain Reaction test results, when compared with symptoms are not always evident. According to our study, thorax CT sensitivity was higher when atypical COVID-19 CT findings were included compared to those with typical COVID-19 CT findings alone. Our study which included the largest number of patients among all other similar studies indicates that not only typical but also atypical CT findings should be considered for an accured diagnosis of COVID-19 pneumonia.

Effectiveness of the rapid emergency medicine score and the rapid acute physiology score in prognosticating mortality in patients presenting to the emergency department with COVID-19 symptoms.

OBJECTIVE: We investigated the effectiveness of the Rapid Emergency Medicine Score and the Rapid Acute Physiology Score in identifying critical patients among those presenting to the emergency department with COVID-19 symptoms. MATERIAL AND METHODS: This prospective, observational, cohort study included patients with COVID-19 symptoms presenting to the emergency department over a two-month period. Demographics, clinical characteristics, and the data of all-cause mortality within 30 days after admission were noted, and the Rapid Emergency Medicine Score and the Rapid Acute Physiology Score were calculated by the researchers. The receiver operating characteristic curve analysis was performed to determine the discriminative ability of the scores. RESULTS: A total of 555 patients with a mean of age of 49.4 ± 16.8 years were included in the study. The rate of 30-day mortality was 3.9% for the whole study cohort, 7.2% for the patients with a positive rt-PCR test result for SARS-CoV-2, and 1.2% for those with a negative rt-PCR test result for SARS-CoV-2. In the group of patients with COVID-19 symptoms, according to the best Youden's index, the cut-off value for the Rapid Emergency Medicine Score was determined as 3.5 (sensitivity: 81.82%, specificity: 73.08%), and the area under curve (AUC) value was 0.840 (95% confidence interval 0.768-0.913). In the same group, according to the best Youden's index, the cut-off value for the Rapid Acute Physiology Score was 2.5 (sensitivity: 90.9%, specificity: 97.38%), and the AUC value was 0.519 (95% confidence interval 0.393-0.646). CONCLUSION: REMS is able to predict patients with COVID-19-like symptoms without positive rt-PCR for SARS-CoV-2 that are at a high-risk of 30-day mortality. Prospective multicenter cohort studies are needed to provide best scoring system for triage in pandemic clinics.

Pharmacologic anisocoria due to nebulized ipratropium bromide: A diagnostic challenge.

Anisocoria may be physiological or seen in fatal conditions, such as intracranial hemorrhage. Newly developing anisocoria may cause confusion and diagnostic difficulty in the emergency department (ED). A 35-year-old female was admitted to the ED with an asthma attack and dyspnea. On examination, the patient was observed to have bilateral rhonchi and was treated with nebulized albuterol (salbutamol) and ipratropium bromide. After the treatment, the dyspnea improved, and mydriasis developed in the left eye (left pupil diameter 9 mm, right 4 mm). An examination revealed that the left pupil was dilated and unreactive to light, but there was no neurological finding. Afterwards, the patient reported that, during the treatment, some aerosol had leaked from the left side of the mask and may have come into contact with her left eye. Given this information, a pilocarpine test was performed, and the patient was diagnosed with pharmacologic anisocoria. The pupil returned to normal within 24 h. Ipratropium bromide is a drug frequently used in patients presenting to the ED with dyspnea. During treatment, nebulized ipratropium may leak from the edge of the facial mask into the ipsilateral eye and may cause mydriasis. A pilocarpine test can be used to differentiate pharmacological anisocoria from other causes, such as third nerve palsy and Adie's pupil. Through the awareness of emergency physicians and the use of the pilocarpine test, a diagnosis can be made without engaging in time-consuming and costly analyses. In addition, this complication can be prevented using masks that better fit the face, as well as protective goggles or eye patches, during treatment.

Correlation between sodium, potassium, hemoglobin, hematocrit, and glucose values as measured by a laboratory autoanalyzer and a blood gas analyzer.

INTRODUCTION: Blood gas analyzers can be alternatives to laboratory autoanalyzers for obtaining test results in just a few minutes. We aimed to find out whether the results from blood gas analyzers are reliable when compared to results of core laboratory autoanalyzers. MATERIALS AND METHODS: This retrospective, single-centered study examined the electronic records of patients admitted to the emergency department of a tertiary care teaching hospital between May 2014 and December 2017. Excluded from the study were patients under 18 years old, those lacking data, those who had any treatment before the laboratory tests, those whose venous gas results were reported more than 30 minutes after the blood sample was taken and for whom any of the laboratory tests were performed at a different time, and recurrent laboratory results from a single patient. RESULTS: Laboratory results were analyzed from a total of 31,060 patients. The correlation coefficients for sodium, potassium, hemoglobin, hematocrit, and glucose levels measured by a blood gas analyzer and a laboratory autoanalyzer were 0.725, 0.593, 0.982, 0.958, and 0.984, respectively; however, there were no good, acceptable agreement limits for any of the parameters. In addition, these results did not change according to the different pH stages (acidosis, normal pH and alkalosis). CONCLUSION: The two types of measurements showed a moderate correlation for sodium and potassium levels and a strong correlation for glucose, hemoglobin, and hematocrit levels, but none of the levels had acceptable agreement limits. Clinicians should be aware of the limitations of blood gas analyzer results.
