The association between coronary artery calcification and vectorcardiography in mechanically ventilated COVID-19 patients: the Maastricht Intensive Care COVID cohort.

BACKGROUND: Coronary artery calcification (CAC) is associated with poor outcome in critically ill patients. A deterioration in cardiac conduction and loss of myocardial tissue could be an underlying cause. Vectorcardiography (VCG) and cardiac biomarkers provide insight into these underlying causes. The aim of this study was to investigate whether a high degree of CAC is associated with VCG-derived variables and biomarkers, including high-sensitivity troponin-T (hs-cTnT) and N-terminal pro-B-type natriuretic peptide (NT-proBNP). METHODS: Mechanically ventilated coronavirus-19 (COVID-19) patients with an available chest computed tomography (CT) and 12-lead electrocardiogram (ECG) were studied. CAC scores were determined using chest CT scans. Patients were categorized into 3 sex-specific tertiles: low, intermediate, and high CAC. Daily 12 leads-ECGs were converted to VCGs. Daily hs-cTnT and NT-proBNP levels were determined. Linear mixed-effects regression models examined the associations between CAC tertiles and VCG variables, and between CAC tertiles and hs-cTnT or NT-proBNP levels. RESULTS: In this study, 205 patients (73.2% men, median age 65 years [IQR 57.0; 71.0]) were included. Compared to the lowest CAC tertile, the highest CAC tertile had a larger QRS area at baseline (6.65 µVs larger [1.50; 11.81], p = 0.012), which decreased during admission (- 0.27 µVs per day [- 0.43; - 0.11], p = 0.001). Patients with the highest CAC tertile also had a longer QRS duration (12.02 ms longer [4.74; 19.30], p = 0.001), higher levels of log hs-cTnT (0.79 ng/L higher [0.40; 1.19], p < 0.001) and log NT-proBNP (0.83 pmol/L higher [0.30; 1.37], p = 0.002). CONCLUSION: Patients with a high degree of CAC had the largest QRS area and higher QRS amplitude, which decreased more over time when compared to patients with a low degree of CAC. These results suggest that CAC might contribute to loss of myocardial tissue during critical illness. These insights could improve risk stratification and prognostication of patients with critical illness.

The Effect of Meteorological Factors on the COVID-19 Pandemic in Northeast Turkiye.

Introduction Although various studies have been conducted on the relationship between meteorological factors and coronavirus disease 2019 (COVID-19), this issue has not been sufficiently clarified. In particular, there are a limited number of studies on the course of COVID-19 in the warmer-humidity seasons. Methods Patients presenting to the emergency departments of health institutions and to clinics set aside for cases of suspected COVID-19 in the province of Rize between 1 June and 31 August 2021 and who met the case definition based on the Turkish COVID-19 epidemiological guideline were included in this retrospective study. The effect of meteorological factors on case numbers throughout the study was investigated. Results During the study period, 80,490 tests were performed on patients presenting to emergency departments and clinics dedicated to patients with suspected COVID-19. The total case number was 16,270, with a median daily number of 64 (range 43-328). The total number of deaths was 103, with a median daily figure of 1.00 (range 0.00-1.25). According to the Poisson distribution analysis, it is found that the number of cases tended to increase at temperatures between 20.8 and 27.2°C. Conclusion It is predicted that the number of COVID-19 cases will not decrease with the increase in temperature in temperate regions with high rainfall. Therefore, unlike influenza, there may not be seasonal variation in the prevalence of COVID-19. The requisite measures should be adopted in health systems and hospitals to manage increases in case numbers associated with changes in meteorological factors.

How Should We Approach Syncope in the Emergency Department? Current Perspectives.

Syncope is a clinical picture that can affect all age groups and has an important place in admissions to the emergency department. There is an important diagnostic challenge in cases where there are different clinical presentations and patients cannot express the situation clearly. Although the emergency department facilities for the diagnosis of syncope are limited, the diagnosis of many patients can be differentiated from life-threatening conditions with a detailed history and physical examination. High-risk patients should be identified and directed for definitive treatment by emergency medicine physicians. This review contains information about the management of the syncope patient in the emergency department.

Vaccine-Induced Myocarditis in Two Intern Doctors in the Same Night Shift.

The coronavirus disease 2019 (COVID-19) pandemic has affected millions of people around the globe and vaccines against the disease have started to develop. Side effects of the vaccine have been reported in the literature, including myocarditis, which has a very low incidence and with a good prognosis. This case report aims to present two medical students' vaccine-induced myocarditis cases after the first doses of BNT162b2.These patients were young males with no previous medical history and both of them had good recovery after the disease. Both of them had their vaccine very recently before the event. These cases show that myocarditis can be seen after the first dose as well.Global vaccination is the most effective prevention method against COVID-19. Considering the fact that morbidities after the disease occur more than the side effects of the vaccine, they are still the best option against the current pandemic.

The diagnostic value of laboratory tests in detecting solid organ injuries in pediatric patients with blunt abdominal trauma.

BACKGROUND: Computed tomography of the abdomen (CT) is used as the gold standard for detecting solid organ injuries (SOI) after blunt abdominal trauma (BAT). However, patient selection for CT is still controversial due to its potential risks. In this study, we aimed to investigate the usefulness of laboratory tests in the detection or exclusion of SOI in pediatric patients evaluated in the emergency department due to BAT. METHODS: The study was planned as a prospective, observational study and was conducted in the emergency department of a university hospital between February 2018 and February 2019. Patients under the age of 18 who were evaluated for BAT in the emergency department were included in the study. In the study, the diagnostic value of abnormal laboratory tests in detecting SOI was calculated by accepting CT results as the gold standard. RESULTS: Of the 323 patients included in the study, 118 (36%) were male. There were 283 patients who underwent CT. SOI was detected in 18 (6%) patients. Abnormal alanine aminotransferase, aspartate aminotransferase, amylase and lipase tests were found to be statistically significant in predicting SOI (p < 0.05). However, none of the tests were found to have sufficient sensitivity and specificity. Hemoglobin, hematocrit, lactate and base excess values were not found to be statistically significant in predicting SOI (p > 0.005). CONCLUSIONS: The hematologic laboratory tests are insufficient to rule out solid organ injury in pediatric patient with BAT.

Violence Against Women During COVID-19 Pandemic: A Comparative Study from a Turkish Emergency Department.

OBJECTIVE: Violence against women (VAW) is a major public health problem and a violation of women's human rights. The coronavirus disease 2019 (COVID-19) pandemic has worsened gender inequality, resulting in a heightened incidence of VAW. This study aims to assess the characteristics of women who admit to the emergency department (ED), both before the pandemic and during the pandemic. The secondary aim is to compare the frequencies of violence cases between periods. METHODS: By single-center, retrospective, and cross-sectional design, the periods of April 10 - December 31, 2020 and April 10 - December 31, 2019 were compared. The outcomes of the study were the daily ED admission numbers of both sexes, the prevalence of VAW cases in the ED, as well as sociodemographic and clinical variables of the women who were exposed to violence. RESULTS: During the pandemic period, number of VAW cases in the ED increased 13% and the ratio of VAW cases to all ED admissions tripled compared to the pre-pandemic period. Women exposed to VAW were more likely to be without social insurance, injured in the trunk part of their body, and having a life-threatening injury in the pandemic period. In both periods, women were attacked by an intimate partner, dominantly (42.6% and 54.1%, respectively). In addition, among all admissions of adults to the ED, women's percentage decreased while men's admission ratios increased during the pandemic period. Admissions to ED declined 47.7% during the COVID-19 pandemic compared to the year before. CONCLUSION: Cases of VAW tend to increase during the pandemic, and health care settings should be well-organized to respond to survivors.

Lactate and base deficit combination score for predicting blood transfusion need in blunt multi-trauma patients.

BACKGROUND: Lactate and base deficit (BD) values are parameters evaluated as indicators of tissue perfusion and have been used as markers of severity of injury and mortality. OBJECTIVES: The aim of the study was to determine the relationship between combined score (CS) and blood transfusion need within 24 h and comparison of the variables between transfusion and non-transfusion group, correlation lactate with BD and with physiological, laboratory parameters, and determining the major risk factors of patients for the need for blood transfusion. METHODS: The study included a total of 359 patients (245 males, median age: 40, min-max: 18-95) with blunt multi-trauma. De-mographics data, laboratory parameters (hemoglobin [Hb], hematocrit [Htc], lactate, BD, pH), physiologic parameters (systolic blood pressure [SBP], diastolic blood pressure [DBP], heart rate [HR], respiratory rate [RR]), shock index (SI), and revised trauma score (RTS) were recorded. Logistic regression method was used to create the CS formula using lactate and BD values. According to this formula, the probability value of 0.092447509 was calculated for the need for blood transfusion within 24 h. If CS was higher than the probability value, the need for blood transfusion within 24 h was considered. Furthermore, univariate analysis was used to determine major risk for blood transfusion need in 24 h, and the receiver operating characteristic curves were performed to compare CS, lactate, BD, SI and RTS. RESULTS: The comparison between transfusion and non-transfusion group there was significance between SBP, DBP, HR, RR, SpO2, Glasgow coma scale, Hb, Htc, lactate, BD, pH, SI and RTS (for each p<0.05). Lactate value has a positive correlation with SI, HR and has a negative correlation with BD, RTS, SBP, and DBP. BD values has a positive correlation with RTS, SBP, DBP, Hb, and Htc and has a negative correlation with SI, HR, and RR. The main risks for blood transfusion need were SI, lactate, BD, SBP, and SpO2%. CS was 0.09 in 100 (27.85%) patients and 41 with high CS had blood transfusion within 24 h (p<0.001; OR21.803, sensitivity 83.7%, specificity 81%,positive predictive value 41%, and negative predictive value 96.9%). A ROC curve showed that CS (AUC: 86.) was more significant than SI and RTS for the need for blood transfusion. CONCLUSION: CS is effective for predicting blood necessity in 24 h for blunt multi-trauma patients.

Diagnostic Value of Hounsfield Unit and Hematocrit Levels in Cerebral Vein Thrombosis in the Emergency Department.

BACKGROUND: Unenhanced computed tomography (CT) is a frequently used imaging method in patients who are evaluated in the emergency department with suspected cerebral vein thrombosis (CVT). OBJECTIVES: The aim of this study was to investigate the usefulness of the Hounsfield unit (HU) value determined by CT and its ratio to the patient's hematocrit (Htc) value in the diagnosis of cerebral vein thrombosis. METHODS: This retrospective study evaluated 41 patients with acute cerebral venous sinus thrombosis and 41 age- and sex-matched control participants. Two experienced observers independently evaluated the CT scan and measured the attenuation of the dural sinuses. RESULTS: There was no significant difference in age, gender, hemoglobin, and Htc values between the two groups. The mean HU value was 75 ± 7 HU in the CVT group and 52 ± 6 HU in the control group (p < 0.001). The mean HU/Htc ratio was 1.9 ± 0.3 in the CVT group and 1.3 ± 0.1 in the control group (p < 0.001). The optimal threshold value for HU was determined as 66, and sensitivity at this value was 93%, and specificity was 98%. The optimal threshold value for HU/Htc was determined as 1.64, and the sensitivity at this value was 90% and the specificity was 100%. CONCLUSION: Hyperattenuation in the dural sinuses and the HU/Htc ratio in unenhanced brain CT scans have high diagnostic value in detecting CVT.

Computed Tomographic Findings of Injuries After Mechanical and Manual Resuscitation: A Retrospective Study.

Introduction Cardiopulmonary resuscitation (CPR)-related injuries are complications of chest compressions during CPR. This study aimed to investigate the differences and complications between mechanical and manual CPR techniques by using computed tomography (CT). Methods Patients in whom return of spontaneous circulation was achieved after CPR and thorax CT imaging were performed for diagnostic purposes were included in the study. Results A total of 178 non-traumatic cardiac arrest patients were successfully resuscitated and had CT scans in the emergency department. The complications of CPR are sternum fracture, rib fracture, pleural effusion/hemothorax, and pneumothorax. There were no statistically significant differences in terms of age, first complaint, cardiac arrest rhythm, CPR duration, and complications between mechanical and manual CPR. The number of exitus in the emergency department was similar (p=0.638). The discharge from hospital rate was higher in the mechanical CPR group but there was no statistically significant difference (p=0.196). The duration of CPR was associated with the number of rib fractures and lung contusion, but it did not affect other CPR-related chest injuries. Conclusion There was no significant difference observed in terms of increased complications in patients who received mechanical compression as compared with those who received manual compression. According to our results, mechanical compression does not cause serious complications, and the discharge from hospital rate was higher than for manual CPR; therefore, its use should be encouraged.

Atrioesophageal Fistula as a Complication of Radiofrequency Ablation for Atrial Fibrillation.

Atrioesophageal fistula (AEF) is an important complication of radiofrequency ablation (RFA). Delayed diagnosis is associated with increased morbidity and mortality. Despite the name "atrioesophageal fistula," fistulas functionally act esophageal to atrial, which accounts for the neurologic and infectious complications. This report presents the management of a 60-year-old male patient who was admitted to the emergency department (ED) with AEF-caused gastrointestinal bleeding. The patient was operated urgently, but he had serious comorbidities and died after the operation. The aim of this case was to evaluate patients who underwent RFA, within 10 days to two months, carefully in the ED and to know the possible complications.
