Bu çalışma, Denizli ili sınırları içinde bulunan Işıklı Gölü'nün bentik makroomurgasızlarını ve dağılımlarını belirlemek amacıyla yapılmıştır. Işıklı Gölü üzerinde belirlenen 7 istasyonda mevsimsel periyotlarla fiziko-kimyasal açıdan incelenmiş ve bentik makroomurgasız örnekleri toplanmıştır. Çalışma sonucunda, gölün bentik faunasının ait 35 taksondan oluştuğu saptanmıştır. Makroomurgasızlar içerisinde en baskın grup Insecta sınıfı olmuştur. Mevsimlere göre taxonların dağılımı ve istasyonlar arasındaki farklılıklar gölün limnolojik yapısına bağlantılı olarak değerlendirilmiştir. Toplanan bentik makroomurgasız örnekleri tür veya cins seviyesinde teşhis edilerek bunların sıklık ve baskınlık analizleri yapılmıştır.
We performed a prospective longitudinal cohort study in two healthcare settings. In total, 909 HCWs out of 3982 (23.35%) were diagnosed with COVID-19 before the vaccination era. Eighty-five per cent of COVID-19 positive HCWs (n = 774) were asymptomatic or mild, and 15% were moderate or severe. The mean age of the infected HCWs in the moderate or severe group was higher than the mild or asymptomatic group (35.4 vs. 31.3 years, p < 0.001). Thirty-two per cent of HCWs were male and the rate of male gender was more frequent in the moderate/severe group (p = 0.009). The rate of those who have cardiovascular diseases (p = 0.003) and diabetes mellitus (p = 0.044) were significantly higher among the HCWs with moderate or severe COVID-19. In multivariate analysis, male gender (OR:1.65, CI:1.11–2.46, p = 0.013), BMI > 30 (OR: 1.9, CI: 1.09–3.51, p = 0.024), and being physician (OR: 2.56, CI:1.45–4.52, p = 0.001) were found to be associated with moderate or severe COVID-19.
Objective: Contact precautions (CP) for the prevention of multidrug-resistant organisms (MDROs) in endemic countries is a critical element of infection control (IC) practices. In this study, we assessed the effectiveness of empiric CP on admission to the hospital in an MDRO endemic region. Methods:The study was carried out in a 300-bed private hospital from January 2016 to September 2018. The CP indications on the day of hospital admission were decided based on determining risk factors such as long term care patients (Group 1), patients with catheters and/or interventions (Group 2), transferred from another hospital (Group 3), patients with known colonisation with MDRO (Group 4), patients with other risk factors (Group 5). Results:In total, 539 consequent patients were observed. The mean age was 63.4 years, and 57% of the patients were male. Most of the patients were from Turkey (94%); however, the rest were mainly from Middle-Eastern and North-African countries. Among 101 out of 539 (18.7%) patients, at least one pathogen was grown, and among 73 out of 539 patients (13.5%), CP requiring pathogen was isolated. The CP requiring pathogens were detected in group 2 (24%), group 1 (19.4%) and group 3 (13%). The most common pathogens were ESBLproducing Enterobacterales (5.8%), carbapenemase-producing Enterobacterales (3.9%), Pseudomonas spp. (3.53%), Acinetobacter spp. (2.97%), vancomycin-resistant enterococci (2.6%) and methicillin-resistant Staphylococcus (1.86%). Conclusion:Risk assessment-based isolation precautions from the day of hospitalisation in an MDRO endemic country were found to be important among high-risk patients such as patients with catheters and/or interventions, long-term care patients and patients transferred from another medical centre. Implementation of risk-based CP than the culture-based IC strategies might be an effective approach in an MDRO endemic region while pending culture results.
