Objective: The absence of a specific biomarker for acute mesenteric ischemia diagnosis results in a delay in diagnosis and treatment, as well as a high mortality rate. The current research examined whether the proteins adropin, HIF-1α, and apelin may be used to help in the early detection of acute mesenteric ischemia. Materials and methods: A total of 20 patients with acute mesenteric ischemia, 20 patients with abdominal pain, and 20 healthy controls were included in the study. The levels of adropin, HIF-1, and apelin in the serum were determined using the ELISA method. Results: Adropin concentrations were significantly higher in the acute mesenteric ischemia group than in the abdominal pain and healthy control groups (p < 0.05). HIF-1α levels were considerably greater in patients with acute mesenteric ischemia compared to both the abdominal pain group and the healthy control group (p < 0.05). There was no difference in apelin levels between the acute mesenteric ischemia and abdominal pain groups (p > 0.05). HIF-1α was found to be moderate (AUC: 0.705) and adropin was found to be a weak biomarker (AUC: 0.692) in the ROC analysis for acute mesenteric ischemia. Conclusion: In this study of 20 patients with acute mesenteric ischemia, we found adropin and HIF-1α levels to be increased compared to patients with abdominal pain who did not have acute mesenteric ischemia.

Objective The objective of the study was to compare the efficacy of point-of-care ultrasound (POCUS) and computed tomography (CT) in the diagnosis of the fracture of the bones that form the elbow joint and the determination of treatment method in elbow injuries. Methods Forty-nine patients aged 5 to 65 years, who were admitted with low-energy elbow injuries, had at least 1 fracture of the elbow joint bones, and underwent CT scanning, were included in this study. Before the initiation of the study, orthopedic surgeons and emergency physicians determined a common treatment based on the fracture characteristics. Patients were first evaluated with direct radiography, and then with POCUS by trained emergency physicians. Emergency physicians made treatment decisions based on the ultrasonography results. Then, CT scans were performed. The CT images were interpreted by radiologists. Orthopedic surgeons made treatment decisions based on the CT interpretations. Results Forty-nine patients with elbow injury were included in the study. Eighteen (37%) patients were women, and 31 (63%) were men. The mean age was 21 ± 15 years. Compared with CT, sensitivity, specificity, positive predictive value, and negative predictive value of POCUS in fracture detection were 97%, 88%, 94%, and 93%, respectively. Although the sensitivity and specificity of POCUS in the decision for reduction were 95% and 100%, respectively, it was 93% and 100% in the decision for surgery. Conclusion In conclusion, POCUS was shown to be successfully applied in the diagnosis and management of elbow injuries, in which direct radiography was inefficient and CT scans were required.

Background The aim of this study was to investigate the role of serum heart-type fatty acid-binding protein (H-FABP) in the evaluation of patients with carbon monoxide (CO) poisoning. Methods Forty patients with acute CO poisoning admitted to the emergency department and 15 healthy adults as the control group were included in the study. Serum H-FABP levels of patients were studied on admission and at the 6th, 12th, and 18th hours. Patients were divided into 3 groups according to clinical severity as mild, moderate, and severe. Patients were also divided into 2 groups according to treatment with hyperbaric oxygen (HBO) or normobaric oxygen. Results Serum H-FABP levels of the patients were higher than those of the control group. There was a negative correlation between H-FABP levels and Glasgow Coma Scale score on admission. Heart-type fatty acid-binding protein levels were significantly higher in patients in the severe compared with mild group. Heart-type fatty acid-binding protein levels in patients treated with HBO were significantly higher than in those treated with normobaric oxygen. The cutoff value of serum H-FABP as an indicator for HBO treatment was determined as 1.5 ng/mL or higher, with a sensitivity of 85.7% and specificity of 69.7%. Serial measurement revealed that H-FABP level peaked at the sixth hour and reduced over time but remained higher than in the control group at the 18th hour. Conclusion Heart-type fatty acid-binding protein may be a promising novel biomarker in the evaluation of clinical severity and in the selection of patients for HBO therapy in acute CO poisoning.
