[Evaluation of Patients Diagnosed with COVID-19 in Terms of Risk Factors]. / COVID-19 Tanili Hastalarin Risk Faktörleri Açisindan Degerlendirilmesi.

Coronaviruses are RNA viruses that can cause disease in the upper and lower respiratory tract in humans and animals. Lately, a new coronavirus causing pneumonia cases was detected in Wuhan, China in December 2019. Soon after, the name of the virus was identified as the "severe acute respiratory syndrome coronavirus-2", and the World Health Organization named the disease coronavirus disease-2019 (COVID-19). In our country, the first cases began to appear in the second week of March. In this study, we aimed to investigate the demographic characteristics and risk factors of patients with the diagnosis of COVID-19. A total of 100 patients (53 female and 47 male) were included in our study. The patients included in the study were randomly selected from the registration system and their information was evaluated retrospectively. The mean age of the patients was 54.42 (Age range= 20-90). When the risk factors for catching the disease were evaluated; it was determined that there was at least one risk factor in 46 patients; 30 patients had close contact with the COVID-19 patient in the social environment (30%) and 16 patients had a travel history outside the city in the last 14 days (16%). The most common symptoms in our patients were; cough (93%), fever (42%), dyspnea (22%), weakness (8%), sore throat (7%), diarrhea (6%), headache (5%) and sputum (2%). The most common comorbid conditions in our patients were detected as hypertension (42%), diabetes mellitus (DM) (21%), congestive heart failure (10%), allergic asthma (7%), chronic obstructive pulmonary disease (6%), rheumatoid arthritis (3%), coronary artery disease (2%), solid organ tumour (2%), depression (1%) and epilepsy (1%). The mean age of our 15 patients who were monitored in intensive care unit was 65 y (± 11.46), the mean age of 85 patients followed in the service was 52.55 (± 16.35) and this difference was statistically significant (p= 0.006). When these two groups were compared in terms of comorbid diseases, the presence of DM was 40% higher (n= 6) in intensive care patients, and this difference was statistically significant (p= 0.05). In addition, the majority [11 patients (73%)] of the patients hospitalized in the intensive care unit were male (p= 0.03). When smoking was evaluated as a risk factor for serious illness, 4 of 11 patients (26%) in intensive care unit had a smoking history, while none of the patients who have died due to COVID-19 had a smoking history. These findings suggested to us that smoking does not increase the severity of COVID-19 disease. As a result, knowledge about the disease should be increased rapidly by sharing the studies on risk factors, transmission routes and clinical features of COVID-19 infection, which affects the whole world.

Central line-associated blood stream infections: characteristics and risk factors for mortality over a 5.5-year period.

BACKGROUND/AIM: Central line-associated bloodstream infections (CLABSIs) are associated with substantial morbidity and mortality and the infection rates vary in a wide range1397645907(high: 62.5%; low: 20%) in developing countries. We aimed to investigate the characteristics and the risk factors for mortality in patients with CLABSIs in intensive care units (ICUs) and provide the relevant data. MATERIALS AND METHODS: The electronic medical records database and file records obtained through active surveillance by an infection control committee of a hospital were screened to identify patients with CLABSIs hospitalized from January 2008 through July 2013. RESULTS: A total of 166 CLABSI episodes in 158 patients out of 17,553 on 38,562 catheter and 94,512 hospitalization days were evaluated. The infection developed in catheterized patients at a median of 14 days (range 2-88), and the highest infection rate with 13.4% (n = 20) was the femoral region among the places where the catheter was inserted. Of the patients catheterized, 54.4% survived whereas 45.6% died. In patients having Candida infection, the mortality was significantly higher. High APACHE II scores and Candida infections were found to be significant risk factors associated with mortality. CONCLUSION: APACHE II scores and bloodstream infection with Candida species were the most powerful predictors of mortality. In ICU practice, health-care givers must consider the emerging role of Candida for both invasiveness and mortality.

Causative pathogens and antibiotic resistance in diabetic foot infections: A prospective multi-center study.

AIM: Clinical practice guidelines for the management of diabetic foot infections developed by the Infectious Diseases Society of America (IDSA) are commonly used worldwide. The issue of whether or not these guidelines need to be adjusted for local circumstances, however, has seldom been assessed in large prospective trials. METHODS: The Turk-DAY trial was a prospective, multi-center study in which infectious disease specialists from centers across Turkey were invited to participate (NCT02026830). RESULTS: A total of 35 centers throughout Turkey enrolled patients in the trial. Overall, investigators collected a total of 522 specimens from infected diabetic foot wounds for culture from 447 individual patients. Among all isolates, 36.4% were gram-positive organisms, with Staphylococcus aureus the most common among these (11.4%). Gram-negative organisms constituted 60.2% of all the isolates, and the most commonly isolated gram-negative was Escherichia coli (15%). The sensitivity rates of the isolated species were remarkably low for several antimicrobials used in the mild infection group. CONCLUSIONS: Based on our findings, several of the antimicrobials frequently used for empirical treatment, including some also recommended in the IDSA guidelines, would not be optimal for treating diabetic foot infections in Turkey. Although the IDSA guideline recommendations may be helpful to guide empiric antimicrobial therapy of DFIs, they should be adjusted to local conditions.
