RESUMO
BACKGROUND: It is known that inflammatory responses play an important role in the pathophysiology of COVID-19. AIMS: In this study, we aimed to examine the role of kynurenine (KYN) metabolism on the severity of COVID-19 disease AQ5. MATERIALS & METHODS: Seventy COVID-19 patients of varying severity and 30 controls were included in the study. In addition to the classical laboratory parameters, KYN, tryptophan (TRP), kynurenic acid (KYNA), 3 hydroxykynurenine (3OHKYN), quinolinic acid (QA), and picolinic acid (PA) were measured with mass spectrometry. RESULTS: TRP, KYN, KYN:TRP ratio, KYNA, 3OHKYN, PA, and QA results were found to be significantly different in COVID-19 patients (p < 0.001 for all). The KYN:TRP ratio and PA of severe COVID-19 patients was statistically higher than that of mild-moderate COVID-19 patients (p < 0.001 for all). When results were examined, statistically significant correlations with KYN:TRP ratio, IL-6, ferritin, and procalcitonin were only found in COVID-19 patients. ROC analysis indicated that highest AUC values were obtained by KYN:TRP ratio and PA (0.751 vs 0.742). In determining the severity of COVID-19 disease, the odd ratios (and confidence intervals) of KYN:TRP ratio and PA levels that were adjusted according to age, gender, and comorbidity were determined to be 1.44 (1.1-1.87, p = 0.008) and 1.06 (1.02-1.11, p = 0.006), respectively. DISCUSSION & CONCLUSION: According to the results of this study, KYN metabolites play a role in the pathophysiology of COVID-19, especially KYN:TRP ratio and PA could be markers for identification of severe COVID-19 cases.

Aim: The use of erythrocyte sedimentation rate (ESR) in coronavirus disease 2019 (COVID-19) to determine disease severity and prognosis is limited. This study aimed to interrogate the diagnostic and prognostic role of ESR compared to other acute-phase reactants. Method: This retrospective cross-sectional study included 493 confirmed and hospitalized adult COVID-19 patients. Pneumonia, radiological severity, oxygen, intensive care requirements, mortality, ESR, and other acute-phase reactant values were recorded. Logistic regression and ROC analysis identified the effect of ESR on mortality and the sensitivity and specificity of the optimal cutoff values of ESR for the prediction of pneumonia, intensive care needs, and mortality and compared these with values for CRP. Results: Of patients, 346 (70.2%) had pneumonia, 98 (19.9%) required intensive care, 183 (37.1%) required oxygen support, and 62 (12.6%) died. ESR data were obtained for 278 patients. Among patients, 80.2% had ESR above 20 mm/h, with a median value of 53 (interquartile range: 49). ESR was higher among those with pneumonia (p < 0.001), requiring oxygen (p < 0.001), and requiring intensive care (p=0.003) compared to those without these, and in exitus patients (p=0.043) compared to survivors. Logistic regression analysis identified that ESR did not impact mortality. ROC analysis found the AUC, cutoff, sensitivity, and specificity results of ESR for pneumonia were 0.827, 37 mm/h, 77%, and 78%; for intensive care were 0.625, 50 mm/h, 74%, and 52; and for mortality were 0.606, 51 mm/h, 71%, and 49%, respectively. However, ROC analysis values for CRP were superior to ESR for all these categories. Conclusion: ESR increased in COVID-19 patients in the presence of pneumonia and severe disease; however, it was not prognostic. Sensitivity and specificity values for pneumonia, intensive care requirements, and mortality were lower than those for CRP.
RESUMO
INTRODUCTION: The study aimed to determine how physicians' professional and institutional characteristics affect their treatment approaches for COVID-19 antiviral and supportive treatment, as well as their demographic characteristics and participation in COVID-19 trainings that may influence these orientations. METHODS: After researching the literature and conducting interviews with the experts, a questionnaire was prepared. The convenience sampling method was used to distribute the questionnaire online to 408 physicians across the nation in January 2021. Exploratory factor analysis was used to verify the research scale, and the Cronbach's Alpha test was used to confirm its reliability. During the data analysis, descriptive and inferential statistical tests were used. RESULTS: It was observed that the physicians were willing to give COVID-19 patients the antivirals but hesitant to provide and suggest supportive care. The training status for COVID-19 treatment was varied. Female physicians prescribed more antiviral drugs than male physicians, received more training, and scored higher across the scale than male physicians ( p = 0.001). The treatment approaches of physicians varied according to their specializations ( p = 0.002) all over the scale. CONCLUSION: The publication of current Ministry of Health guidelines on a variety of themes related to COVID-19 treatment, as seen in Turkey, is both beneficial and important. However, because all physicians, regardless of specialty, are affected by current and will be in the future pandemics, it is necessary to design and maintain a continuous training program on pandemics and their management for all physicians.

To evaluate the etiology and characteristics of vertebral osteomyelitis cases in our country, patients with vertebral osteomyelitis between January 2000 and December 2007 were included in this study. Clinical and laboratory data of the patients were collected from the medical records retrospectively. Of these 100 patients, 44 had pyogenic, 24 had brucellar, and 32 had tuberculous spondylodiscitis. The age of the patients ranged from 13 to 82 years, with a mean of (SD±) 55 ± 15.6 years. Within the pyogenic group, 10 (22.7%) patients had a spinal surgery history, and in 18 patients of the pyogenic group, an etiological agent was isolated. Ten (56%) of these 18 were methicillin-sensitive Staphylococcus aureus. While all of the patients included in this study suffered from pain, 49 of these had fever. Sixty-nine percent of the patients had lumbar involvement. The etiological distribution may differ according to geographical areas. Although brucella and tuberculosis (TB) are endemic in our country, pyogenic vertebral osteomyelitis was more frequent. The most common involved area in our patients was the lumbar vertebrae. Although thoracic involvement may be more predominant in tuberculous vertebral osteomyelitis, it does not strongly suggest TB. Magnetic resonance imaging may exclude some disorders mimicking vertebral osteomyelitis and may delineate the degree of the involvement. Microbiological and/or histopathological examination of computerized tomography-guided fine-needle aspiration biopsies are the mainstays for the diagnosis. Suspicion and early diagnosis seem critical for preventing sequelae development.

Background: Rabies disease is zoonotic disease-causing encephalitis and resulting in death. It is possible to prevent the disease with suitable prophylaxis approaches. This study examined the compliance of post-exposure prophylaxis approaches with the guidelines and the reasons for non-compliance in contact cases at risk of rabies. Methods: This retrospective cross-sectional study includes patients who continued the vaccination program from 2014-2018 at the Ordu University Medical Faculty Hospital Rabies Vaccination Center in Ordu, Turkey. Cases were assessed in terms of sociodemographic features, previous rabies vaccination history, features of the contact with rabies risk, attendance duration after contact, and whether all stages of prophylaxis were completed after contact. Results: Of the 748 cases attending the vaccination center, the age range was 1- 91 yr, with a mean age of 28.12 ± 21.60 yr. Of cases, 62.3% were male (n =466) and 37.7% were female (n =282). Of risky contact, 60% comprised stray animals. Of recorded cases, 55.2% displayed approaches compatible with guidelines. Among incompliant approaches, the most frequent was administering vaccines even though observation was sufficient. (n = 174, 52%). Conclusion: Contact with risk of rabies may result in insufficient administration of the stages in prophylaxis after contact, or contrarily, mistaken administration based on acting with a sense of excessive safety. Stray dogs or domestic animals without sufficient vaccinations comprise a significant risk despite all efforts. In order to prevent risky contact, there is a need for the development of correct strategies and to ensure continuity of in-service training for health professionals.
RESUMO
BACKGROUND: Brucellosis is one of the most common zoonotic diseases in the world. Osteoarticular complications, especially vertebral system involvement, are most commonly reported. However, reports and coreports of pulmonary complications and thoracal spondylodiscitis and epidural abscess are rare. CASE PRESENTATION: Spondylodiscitis was detected at the T11-12 vertebral level, followed by epidural and paravertebral abscess, and then empyema was detected in a 17-year-old Asian female patient without any additional disease. The patient had used various antibiotics and the disease could not be proven bacteriologically. Also, the Rose Bengal test was negative. However, serologically high titer Brucella positivity was detected in the blood and pleural fluid sample. Drainage was required for bilateral empyema. Disease duration prolonged due to multiple complications. The patient was cured with combined long-term treatment for brucellosis. CONCLUSIONS: Although some are rare, brucellosis is a zoonotic disease that can cause many complications. The gold standard for diagnosis is the growth of bacteria in blood culture or tissue culture. However, isolation of the microorganism can be very difficult. Clinical suspicion and serological tests are important guides.

Malaria is a condition that threatens millions of people in many countries in spite of precautions. Sporadic cases have not been observed in our country since 2010, but imported malaria cases are still to be seen because of migration. In this study, two malaria cases are presented that appeared in a non-endemic region within 1 week. Complaints appeared 20 days later after leaving Ivory Coast in the first case and one week after returning from Ghana in the second case. With this two import cases which have a travel story about two different countries and non taking regular chemoprophylaxis; it is aimed to call attention that malaria is a question of common concern and a protozoon which needs to be struggled worldwide.

Brucellosis is a systemic infectious disease caused by Gram-negative bacilli, the genus Brucella, and clinical features are diverse. Therefore, several infectious and non-infectious diseases are considered in its differential diagnosis. In this study, we aimed to determine the positivity rate of Brucella agglutination tests in the culture-positive brucellosis and in diseases mimicking brucellosis clinically.Thirty patients with culture-positive brucellosis, and 280 patients with the diseases mimicking brucellosis clinically (20 with miliary tuberculosis, 33 with malaria, 20 with typhoid fever, 20 with adult-onset Still's disease, 47 with systemic lupus erythematosus, 50 with rheumatoid arthritis, 27 with sarcoidosis, and 63 with active lymphoma) were included in the study. Brucella agglutination tests (Rose-Bengal and Wright) were studied in serum samples of these 310 patients. Both Rose-Bengal and Wright tests (the latter in a titer of 1/160 or higher) were positive in all patients with brucellosis. For the other diseases, the test was slightly positive (1/40) in one patient with malaria and another with non-Hodgkin's lymphoma, and weakly positive (1/20) in a patient with typhoid fever. It remained negative in the remaining. In conclusion, agglutination tests currently used in the diagnosis of brucellosis are very sensitive and specific. Brucellosis can be effectively excluded from the diseases having similar clinical features by the use of agglutination tests.
