Background: The average frequency of thrombosis in patients with COVID-19 is still high despite low molecular weight heparin (LMWH) prophylactic. Global hemostasis assays, particularly thrombodynamics (TD), known to be sensitive to both hypercoagulation and heparin effects, could potentially be useful for individual management of anticoagulant therapy.
Methods: A total of 74 patients with lung involvement >50% were randomized into two groups: Group A (44 patients) received weight-based dosing of LMWH, and Group B (30 patients) received the first LMWH dose by a weight-based dosing protocol and then received an adjusted dose based on TD daily results.
The progression of secondary pulmonary damage in SARS-COV-2 infection, associated with interstitial damage, inflammation and alveolar consolidation and eventually resulted in the development of pulmonary fibrosis (PF), remains one of the key clinical dilemmas for the treatment of patients in intensive care units (ICU). Currently, there is no standardized algorithm for PF prevention and timely management, although few studies have discussed the use of antifibrotic agents in COVID-19 patients. One of the treatment options for patients with interstitial PF, when irresponsive to the given corticosteroid therapy, is the administration of cytostatic agents, in particular, cyclophosphamide.

The obtained colloidal solutions of electrostatically stabilized Ag NPs do not show any agglomeration for several months. Apart from an atomic thin oxide layer and the relatively weakly bound OH ions, the surface of Ag NPs can be considered as stabilizer-free.

On the basis of this analyses the conclusions were drawn about the influence of parameters of construction on values of maximum sag and maximum bending moment. The recommendations for the usage of the simplified model were done.
