Comparison of Candida colonization in intensive care unit patients with and without COVID-19: First prospective cohort study from Turkey.

Candida species are the primary cause of fungal infections in intensive care units (ICUs). Despite the increasing prevalence of Candida-related infections, monitoring the progression of these infections from colonization in COVID-19 ICU patients lacks sufficient information. This study aims prospectively to compare 62 COVID-19 and 60 non-COVID-19 ICU patients from admission to discharge in terms of colonization development, rates, isolated Candida species, risk factors, and Candida infections during hospitalization.

Objectives: Management of malignant gastrointestinal (GI) obstruction presents a significant challenge. Most patients are in a profoundly decompensated state due to underlying malignancy and are not ideal candidates for invasive surgical procedures. Self-expandable metallic stents (SEMSs) are used to provide permanent or temporary patency in all endoscopically accessible stenosis of the GI tract.

Criteria for Hyperinflammation Developing in COVID-19: Analysis of 2 Cohorts From Different Periods of the Pandemic.

Objective: Hyperinflammation (HI) that develops in week 2 of COVID-19 contributes to a worse outcome. Because week 2 laboratory findings can be relatively mild, the available criteria for classification of hemophagocytic lymphohistiocytosis or macrophage activation syndrome are not helpful.

Methods: Our study included a discovery cohort of patients from Turkey with symptomatic COVID-19 who were followed up while hospitalized during the initial wave and a replication cohort of hospitalized patients from a later period, all of whom required oxygen support and received glucocorticoids.

Remdesivir treatment for patients with moderate to severe COVID-19.

Background: Remdesivir, which was first developed for the treatment of Ebola disease but failed to meet expectations, has become hope in the fight against the COVID-19 pandemic. This study aimed to evaluate risk factors for mortality and prognosis of adult moderate/severe COVID-19 patients treated with remdesivir, and safety and tolerability of 5 days of remdesivir treatment.

Methods: This multicenter prospective observational study was conducted in 14 centers in Turkey.

activities of antibiotic combinations against mature biofilms of ventilator-associated pneumonia isolates.

The authors aimed to determine the efficacy of frequently used antibiotics, alone or in combination, against biofilms of ventilator-associated pneumonia isolates. The authors determined the MICs, minimum biofilm inhibitory concentrations and minimum biofilm eradication concentrations of meropenem, ciprofloxacin and colistin as well as their combinations against planktonic forms and biofilms of , and clinical isolates. Generally, the minimum biofilm inhibitory concentrations and minimum biofilm eradication concentrations of the antibiotics were 1000-fold higher than their MICs, and synergy was provided by different concentrations of meropenem-colistin and meropenem-ciprofloxacin combinations with checkerboard and time-kill curve methods.

Dipyridamole does not have any additive effect on the prevention of COVID-19 coagulopathy.

Objective: Severe acute respiratory syndrome (SARS) coronavirus 2 (SaRS-Cov-2) associated respiratory disease (COVID-19), announced as a pandemic, is a multisystem syndrome. SARS-CoV-2 directly infects and damages vascular endothelial cells, which leads to microvascular dysfunction and promotes a procoagulant state. Dipyridamole (DP) acts as a reversible phosphodiesterase inhibitor and is used mainly as an antiplatelet agent.

Biofilm formation of panresistant .

The authors aimed to investigate the biofilm-forming features of panresistant (PRKp). The biofilm formations were shown under light microscope and laser scanning confocal microscopy. The optical densities of the wells were measured and classified according to biofilm-forming capacities.

Case Report: Severe COVID-19 Pneumonia in a Patient With Relapsed/Refractory Hodgkin's Lymphoma.

First identified in China in December 2019, coronavirus disease 2019 (COVID-19) has rapidly evolved into a global pandemic. The presence of haematological malignancies are expected to increase the risk of adverse outcomes from this viral infection due to the immunosuppression brought about by the underlying cancer and the effects of therapy. We present a 55-year-old woman diagnosed with relapsed/refractory Hodgkin's lymphoma (HL) who had been heavily pretreated with multiagent chemotherapy, autologous hematopoietic stem cell transplantation (autoHCT), allogeneic hematopoietic stem cell transplantation (alloHCT) and was complicated with EBV associated posttransplant lymphoproliferative disease (PTLD) and chronic graft-versus-host-disease (GVHD).
