[Investigation of hsa-miR-1908 and hsa-miR-144 Expression Levels in Crimean-Congo Hemorrhagic Fever Patients]. / Kirim-Kongo Kanamali Atesi Hastalarinda hsa-miR-1908 ve hsa-miR-144 Ifade Düzeylerinin Arastirilmasi.

Crimean-Congo hemorrhagic fever (CCHF) is a tick-borne zoonotic viral disease. MicroRNAs (miRNAs), which play an important role in the regulation of gene expression, are involved in many processes essential for cell life such as development, differentiation, survival, apoptosis and aging. If miRNAs fail to fulfill their functions, they cause susceptibility to many diseases, including viral infections or cause the disease to be experienced in different clinical situations, such as severe or mild. In this study, we aimed to determine the expression levels of hsa-miR-144 and hsa-miR-1908 in CCHF patients and to compare the results in different clinical courses of CCHF disease. In this study, expression levels of hsa-miR-144 and hsa-miR-1908 were detected by quantitative reverse transcription polymerase chain reaction (RT-qPCR) in blood samples obtained from 60 CCHF patients and 40 healthy individuals. We also investigated the differences in the expression levels of the microRNAs between patients with severe and non-severe disease or between patients who died and survived. Quantitative polymerase chain reaction data were uploaded to the "Data Analysis Center" (Qiagen, Germany) and analyzed using the ΔΔCq (ΔΔCt) method. p value was calculated according to Student's t test for genes in the study groups. The expression level of hsa-miR-144 decreased (fold change= 0.09) and the expression level of hsa-miR-1908 increased 1.44-fold in CCHF patients compared to the control group. The expression of hsa-miR-144 and hsa-miR-1908 increased 2 and 2.36-fold, respectively, in severe patients compared to non-severe patients. The expression levels of hsa-miR-144 and hsa-miR-1908 were 16.3- and 14.3-fold higher, respectively, in fatal cases compared to surviving patients and these results were statistically significant. In addition, the expression level of hsa-miR-144 was significantly decreased in patients with low leukocyte counts and the expression level of hsa-miR-1908 was significantly increased in patients with prolonged prothrombin time (PT). This is the first study in the literature investigating the expression level of hsa-miR-1908 in CCHF patients. In conclusion, the data of this study suggest that hsa-miR-144 and hsa-miR-1908 may be important biomarkers in predicting the prognosis and clinical course of CCHF disease.

Investigation of hematologic findings related to brucellosis in Anatolian region.

OBJECTIVES: To investigate the prevalence of hematologic findings and the relationship between hemogram parameters and brucellosis stages in patients. METHODS: This multi-center study included patients older than 16 years of age who were followed up with a diagnosis of brucellosis. Patients' results, including white blood cell, hemoglobin, neutrophil, lymphocyte, monocyte, mean platelet volume, platelet and eosinophil counts were analyzed at the initial diagnosis. RESULTS: In this study 51.3% of the patients diagnosed with brucellosis were male. The age median was 45 years for female and 41 years for male. A total of 55.1% of the patients had acute brucellosis, 28.2% had subacute, 7.4% had chronic and 9% had relapse. The most common hematologic findings in brucellosis patients were anemia (25.9%), monocytosis (15.9%), eosinopenia (10.3%), and leukocytosis (7.1%). Pancytopenia occurred in 0.8% of patients and was more prominent in the acute phase. The acute brucellosis group had lower white blood cell, hemoglobin, neutrophil, eosinophil, and platelet counts and mean platelet volume, and higher monocyte counts compared to subacute and chronic subgroups. CONCLUSION: It was noteworthy that in addition to anemia and monocytosis, eosinopenia was third most prominent laboratory findings in the study. Pancytopenia and thrombocytopenia rates were low.

Surgical Antimicrobial Prophylaxis Compliance in Turkey: Data from the Prospective, Observational, Multicenter Survey Including 7,978 Surgical Patients.

Background: Surgical antimicrobial prophylaxis (SAP) is the peri-operative administration of antimicrobial agents. Compliance rates vary worldwide from 15% to 84.3%, with studies in Turkey not exceeding 35%. The aim of this multicenter study was to determine the rate of appropriate antibiotic class, timing, and duration as well as discharge prescriptions in Turkey. Thus, we aimed to determine the rate of full compliance with SAP procedures in our country Patients and Methods: This multicenter, prospective, observational, descriptive study was conducted in 47 hospitals from 28 provinces in seven different regions of Turkey. Patients over 18 years of age in all surgical units between June 6, 2022, and June 10, 2022, were included in the study. Results: Of the 7,978 patients included in the study, 332 were excluded from further analyses because of pre-existing infection, and SAP compliance analyses were performed on the remaining 7,646 cases. The antibiotic most commonly used for SAP was cefazolin (n = 4,701; 61.5%), followed by third-generation cephalosporins (n = 596; 7.8%). The most common time to start SAP was within 30 minutes before surgery (n = 2,252; 32.5%), followed by 30 to 60 minutes before surgery (n = 1,638; 23.6%). Surgical antimicrobial prophylaxis duration was <24 hours in 3,516 (50.7%) patients and prolonged until discharge in 1,505 (21.7%) patients. Finally, the actual proportion of patients compliant with SAP was 19% (n = 1,452) after omitting 4,458 (58.3%) patients who were prescribed oral antibiotic agents at discharge as part of a prolonged SAP. Conclusions: Surgical antimicrobial prophylaxis compliance rates are still very low in Turkey. Prolonged duration of SAP and especially high rate of antibiotic prescription at discharge are the main reasons for non-compliance with SAP.
