Perfusion index: could it be a new tool for early identification of pulmonary embolism severity?

Perfusion index (PI) is a promising indicator for monitoring peripheral perfusion. The present study aimed to compare the efficiency of PI and PESI score in estimating the 30-day mortality and treatment needs of patients diagnosed with pulmonary embolism in the emergency department. This study was prospective and observational. The demographic features of the patients, comorbidities, vital signs, PESI score, PI, treatment applied to the patient and airway management, right ventricular diameter/left ventricular diameter ratio, length of hospital stay, outcome, and 30-day mortality were recorded. A total of 94 patients were included. All patients' vital signs and PI values were recorded on admission. The mean pulse rate (p = 0.001) and shock index (p = 0.017) values of deceased patients were statistically significantly higher, while the mean PI (p = 0.034) was statistically significantly lower. PESI score and PI were statistically significant to predict the need for mechanical ventilation (PI, p = 0.004; PESI score, p < 0.001), inotropic treatment (PI, p = 0.047; PESI score p = 0.005), and thrombolytic therapy (PI, p = 0.035; PESI score p = 0.003). According to the ROC curve, the mortality prediction power of both PESI (AUC: 0.787, 95% CI 0.688-0.886, cutoff: 109.5, p < 0.001) and PI index (AUC: 0.668, 95% CI 0.543-0.793, cutoff: 1, p = 0.011) were determined as statistically significant. PI might be helpful in clinical practice as a tool that can be applied to predict mortality and treatment needs in PE.

Mortality predictors of patients diagnosed with severe hyponatremia in the emergency department.

PURPOSE: To determine the factors affecting mortality as a result of the analysis of the demographic and clinical characteristics and laboratory parameters of patients whose serum Na value was determined to be 125 mEq/L or below at the time of admission to the emergency department (ED). METHOD: Patients over 18 years of age who admitted to the ED of a tertiary hospital between September 2021 and September 2022 and whose serum sodium level was determined to be 125 mEq/L and below were included in the study. Demographic and clinical characteristics, admission complaints, medications used, Charles comorbidity index (CCI), laboratory parameters, and outcomes of the patients included in the study were recorded in the data form. RESULTS: Three hundred ninety-nine patients were included in the study. When the 30-day mortality of the patients is examined, the mortality rate was found to be 21.6%. In the analyses performed for the predictive power of laboratory parameters for mortality, it was determined that the highest predictive power among the predictive values determined by the area under the curve (AUC) was the albumin level (AUC 0.801, 95% CI 0.753-0.849, p < 0.001). In the binary logistic regression analysis, urea and albumin were independent predictors of 30-day mortality. CONCLUSION: According to study data, albumin and urea levels are independent predictors of 30-day mortality in patients diagnosed with severe hyponatremia in the emergency department.

Predictors of 30-day mortality in patients diagnosed with hepatic encephalopathy on admission to the emergency department.

BACKGROUND: The aim of this study is to compare the laboratory findings and disease severity scores of patients diagnosed with hepatic encephalopathy (HE) in the emergency department (ED) to predict 30-day mortality. METHOD: The patients over 18 years old and diagnosed HE in the ED of a tertiary hospital were included in the study. Demographic and clinical characteristics, laboratory parameters, predisposing causes and outcomes of the patients included in the study were recorded in the data form. Severity of liver disease was assessed by Child Pugh Score (CPS), End-stage liver disease model (MELD), MELD-Na and MELD-Lactate scores. RESULTS: Two hundred fifty-four patients diagnosed with HE were included in the study. 59.1% of the patients were male. The mean age of the patients was 65.2 ±â€…12.6 years. The mortality rate of the patients was 47.2%. When the receiver operating characteristic (ROC) analysis, which determines the predictive properties of laboratory parameters and disease severity scores, was examined, the area under curve value of the MELD-Lactate score (0.858 95% CI 0.812-0.904, P  < 0.001) was the highest. Binary logistic regression analysis for the estimation of patients' 30-day mortality showed that CPS and MELD-Lactate scores and blood ammonia and B-type natriuretic peptide levels were independent predictors of mortality. CONCLUSION: According to the study data, MELD-Lactate and BNP levels in patients diagnosed with HE in the ED may help the clinician in the prediction of 30-day mortality in the early period.

Comparison of syncope risk scores in predicting the prognosis of patients presenting to the emergency department with syncope.

BACKGROUND: Various scores have been derived for the assessment of syncope patients in the emergency department (ED). AIM: We aimed to compare the effectiveness of Canadian Syncope Risk Scores (CSRS), San Francisco Syncope Rules (SFSR), and Osservatorio Epidemiologico sulla Sincope nel Lazio (OESIL) risk scores in predicting the risk of major adverse cardiac events (MACE) and mortality among syncope patients within 30 days of the initial ED visit. METHODS: We performed a prospective, observational case series study of adults (≥ 18 years) with unexplained syncope/near-syncope who presented to ED. Demographic characteristics of the patients and clinical and laboratory data were recorded in the standard data collection form of the study. Our primary outcome was a 30-day mortality. RESULTS: A total of 421 patients (mean age 50.9 ± 20.8, 51.5% male) were enrolled. The rate of MACE development in the 30-day follow-up of the patients was 12.8% (n = 54). While 20.2% (n = 85) of the patients were hospitalized, two of the patients died in the emergency room and the 30-day mortality was 5.5% (n = 23). CSRS was found to have the highest predictive power of mortality (AUC: 0.869, 95% CI 0.799-0.939, p < 0.001). If the cut-off value of CSRS was 0.5, the sensitivity was found to be 82.6% and the specificity was 81.9%. Also CSRS (OR: 1.402, 95% CI: 1.053-1.867, p = 0.021) was found to be an independent predictor of the 30-day mortality. CONCLUSION: The CSRS may be used as a safety risk score for a 30-day risk of MACE and mortality after discharge from the emergency department.

BUN/albumin ratio predicts short-term mortality better than SYNTAX score in ST-elevation myocardial infarction patients.

OBJECTIVE: The aim of the study is to compare the prognostic power of the BUN/albumin ratio (BAR) calculated on admission to the emergency department and the SYNergy between Percutaneous Coronary Intervention with TAXus (SYNTAX) score calculated after coronary angiography (CAG) in predicting 30-day mortality in patients with ST-segment elevation myocardial infarction (STEMI). METHOD AND MATERIAL: The study was conducted prospectively between March 2021 and March 2022 in the emergency department of a tertiary hospital. Patients over the age of 18 who underwent CAG with a diagnosis of STEMI were included in the study. Demographic charecteristics, comorbidities, laboratory parameters of the patients at the time of admission and SYNTAX (SX) score were recorded in the data form. RESULTS: A total of 1147 patients (77% male) diagnosed with STEMI were included in the study. When the receiver-operating characteristic analysis for SX score and laboratory parameters' power to predict mortality was examined, it was found that the AUC value of the BAR level (AUC: 0.736; 95% confidence interval: 0.670-0.802, P  < 0.001) was the highest. If the threshold value of the serum BAR level, which was determined to predict mortality, was taken as 4, the sensitivity was found to be 76.7% and the specificity was 56.9%. With multivariate logistic analysis, it was determined that the risk of mortality increased by 1.25 for each unit increase in the BAR value in STEMI patients ( P  < 0.001). CONCLUSION: According to the study data, the BAR may guide the clinician in the early period as a practical and valuable predictor of 30-day mortality in patients diagnosed with STEMI.

A fatal case of acetamiprid poisoning with turquoise urine.

Acetamiprid is a member of neonicotinoid insecticides with a low risk of toxicity in humans. However, ingestion of large amounts may cause severe poisoning. This is the first case reported in the literature in which severe toxicity and death occurred after acetamiprid ingestion. A 57-year-old male patient consumed 50g/250mL of an insecticide formulation containing acetamiprid for suicidal purposes. The ambulance team performed cardiopulmonary resuscitation on the patient who had a cardiac arrest. His heart beat returned after a 15-min cardiopulmonary resuscitation, and afterward, he had tachycardia, hypotension, respiratory failure, high gap metabolic acidosis with a high lactate, hypokalemia, hypocalcemia, mydriasis, and coma. The patient underwent supportive treatment for a variety of symptoms. However, he died despite all supportive treatment. This case demonstrates that ingestion of large amounts of the acetamiprid and late presentation can be fatal despite all supportive care.

Evaluation of Nutrition Risk in Patients Over 65 Years of Age With Nontraumatic Acute Abdominal Syndrome.

BACKGROUND: The objective of this study is to investigate the power of CRP/Albumin ratio, NRS-2002, mNUTRIC scores to predict nutritional needs and mortality in patients over 65 years of age diagnosed with acute abdominal syndrome in the emergency department and then transferred to the surgical intensive care unit. MATERIAL AND METHOD: CRP/Albumin ratio, APACHE II, SOFA, NRS-2002 and mNUTRIC scores were calculated. The analysis of the data was conducted in IBM SPSS Statistics Base 22.0 package program. RESULTS: In the analytical evaluation made for nutritional needs, AUC value for mNUTRIC was found to be: 0,683, 95% CI 0,611-0,755, p < 0.001. It was found out that mortality of patients had a statistically significant and moderate correlation with mNUTRIC score (r = 0.537; p < 0.001). In the analytical evaluation made for mortality, mNUTRIC's AUC value (AUC: 0.808, 95% CI 0.736-0.880, p < 0.001) was found to be the highest. When the cut-off value determined to predict mortality was taken as 3.5 for mNUTRIC score, sensitivity was 75.9% and specificity was 69.4%. CONCLUSION: The evaluation of the risk of malnutrition through nutritional risk tools in intensive care patients over 65 years of age with acute abdominal syndrome can also predict nutritional needs in the early period besides mortality. Based on our data, the fact that mNUTRIC score cut-off value in older patients hospitalized in intensive care is 3.5 and higher may be a predictor for ICU mortality.
