Highlights Earlier use of tocilizumab in COVID-19 infection is beneficial for survival, length of hospitalization and duration of oxygen support Administration of tocilizumab is based on an increase in requirements of oxygen support, progression of thoracic CT, elevation of inflammation IL-6, CRP, ferritin, d -dimer, and decrease in % lymphocytes Among the inflammation parameters, the earliest changes were detected at the levels of CRP, IL-6 and % lymphocytes

We aimed to describe the increased rate of Acinetobacter baumannii infections during the COVID-19 pandemic and define its significance within the last five years. This study was performed in a tertiary hospital with 280 beds and included all patients infected with A. baumannii in the intensive care unit between January 1, 2018, and June 30, 2022. A. baumannii-infected patients in the intensive care unit 27 months before the pandemic and 27 months during the pandemic were included. Pulsed-field gel electrophoresis was performed to assess clonal relatedness. The infection control measures were specified based on the findings and targeted elimination. In total, 5718 patients were admitted to the intensive care unit from January 1st, 2018, to June 30th, 2022. A. baumannii infection was detected in 81 patients. Compared to the pre-pandemic era, the rate of A. baumannii infection during the pandemic was 1.90 times higher (OR: 1.90, 95% CI: [1.197, 3.033]). Clonality assessment of multidrug-resistant A. baumannii samples revealed eight clusters with one main cluster comprising 14/27 isolates between 2021 and 2022. The case fatality rate of the pre-pandemic and pandemic era was not different statistically (83.33% vs. 81.48%, p = 0.835). Univariate analysis revealed the association of mechanical ventilation (p = 0.002) and bacterial growth in tracheal aspirate (p = 0.001) with fatality. During the COVID-19 pandemic, potential deficits in infection control measures may lead to persistent nosocomial outbreaks. In this study, the introduction of enhanced and customized infection control measures has resulted in the containment of an A. baumannii outbreak.

Clostridioides difficile-associated pseudomembranous colitis (PMC) is a life-threatening inflammatory bowel disease. Here, we aimed to present a 40-year-old woman at 25 weeks of gestation whose pregnancy was terminated earlier than expected. Unfortunately, despite fidaxomicin and oral vancomycin, the patient’s diarrhea did not improve, and she had to undergo a subtotal colectomy. C. difficile infections developing in pregnant women can be catastrophic for both baby and maternal health. Also, antibiotic stewardship is crucial in the prevention of PMC. Therefore, unnecessary and prolonged use of antibiotics should be avoided. Keywords: Clostridioides difficile, pregnant, colectomy, colitis

Coronavirus disease-2019 (COVID-19) is a major global human threat caused by severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2). Following the first pneumonia case in China in December 2019, humanity faced a dreadful infection in a short period when the World Health Organization declared a pandemic on March 11, 2020. This review aims to look at the epidemiology of COVID-19, the virological characteristics of SARS-CoV-2, and the methods of transmission and prevention.
