Coronavirus disease—COVID-19 (coronavirus disease 2019) has become the cause of the global pandemic in the last three years. Its etiological factor is SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus type 2). Patients with diabetes (DM—diabetes mellitus), in contrast to healthy people not suffering from chronic diseases, are characterised by higher morbidity and mortality due to COVID-19. Patients who test positive for SARCoV-2 are at higher risk of developing hyperglycaemia. In this paper, we present, analyse and summarize the data on possible mechanisms underlying the increased susceptibility and mortality of patients with diabetes mellitus in the case of SARS-CoV-2 infection. However, further research is required to determine the optimal therapeutic management of patients with diabetes and COVID-19.
Uterine tumors are a challenge encountered by every gynecologist in clinical
practice. In the era of increasing incidence of endometrial cancer in the general
population of women at reproductive age, compared to other genital malignancies, we
should not forget about other tumors originating from the mucous and muscular layer of
the uterus. Clear ultrasonographic differentiation of uterine tumors into benign
(myomas) and malignant (sarcomas) lesions may sometimes prove impossible. Myomas, the
most common uterine tumors, are characterized by discrete vascularization on color
Doppler and high blood flow velocity as well as the lack of early diastolic notch on
Doppler ultrasound. Sarcomas, on the other hand, show characteristic rich
vascularization. Rapid tumor growth should also be noted when making the diagnosis.
There are multiple known causes of uterine tumors. So far, no clear Doppler flow markers
have been identified to characterize benign and malignant lesions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
