A total of 1 878 489 people were infected and 119 044 people were lost because of the disease and its complications by 15 April. Severe morbidity and mortality complications are mostly seen in elderly and patients having comorbidities. Diabetic foot ulcers (DFUs) are one of severe complications of diabetes mellitus and it may require urgent surgical interventions. In this paper, we aimed to create a management algorithm to prevent the unexpected complications that may occur in the patients and health care workers during the evaluation of COVID-19 in DFU patients who require urgent surgical intervention. We advise the use of thorax computerised tomography for preoperative screening in all DFU patients with severe signs of infection and especially those requiring urgent surgery for both the detection of the possible undiagnosed COVID-19 in the patient for the need for close follow-up and protection of the surgical and anaesthesiology team.A nonplanar polylactide scaffold to be used in tissue engineering was obtained by freeze-extraction method. Properties of the scaffold were modified by adding Eudragit® E100. The impact of the modification on morphology, porosity and pore size, mass absorbability, mechanical properties was determined. Scanning electron microscopy (SEM), hydrostatic weighing test, static compression test was used to this end. The chemical composition of the scaffold was defined based on infrared spectroscopy (FTIR) and energy-dispersive X-ray spectroscopy (EDX). Biocompatibility was confirmed by quantitative tests and microscopic observation. The obtained results show that the obtained scaffolds may be applied as a carrier of hydrophilic cellular growth factors for more efficient tissue regeneration.Objectives To report on a retrospective study of individual funding request (IFR) submissions from a large tertiary hospital and describe gaps in
