Opis:: Haemostatic materials such as: gelatine sponges, oxygenated cellulose meshes, tissue sealants, collagen matrices with human thrombin and fibrinogen are gaining on popularity in gastrointestinal surgery, especially in colorectal surgery. We searched for available scientific publications in the Pubmed and Cochrane database on the use of individual hemostatic materials in the field of gastrointestinal surgery. The analysis focused on the assessment of the safety of the use of individual materials in terms of the rate of bleeding complications and the rate of anastomotic leakage cases. The use of haemostatic materials has for years been a recognized method of reducing the rate of intra- and postoperative complications, both in gastrointestinal surgery and in other surgical specialties. Based on the available studies, it can be concluded that the use of hemostatic materials such as matrices, sponges and adhesives in gastrointestinal surgery, even in patients at high risk of anastomotic leakage and bleeding complications, reduces the incidence of complications. The growing popularity of haemostatics and sealants in surgery means that they are currently used in a wide range of indications, and surgeons are more and more willing to use them even in case of standard surgical procedures, which is reflected in the available studies. Choosing a haemostat should be a conscious decision, taking into account the site and type of bleeding, mechanism of action, ease of use, efficacy, safety, and price, among others.

Opis:: Przeprowadzanie nurkowań i dekompresji według opracowanych tabel dekompresyjnych nawet skorygowanych dopplerowską oceną przebiegu desaturacji nie zabezpiecza w pełni nurków przed wystąpieniem objawów DCS czy jałowej martwicy kości. Nadal, zatem poszukiwane są bardziej czułe i specyficzne parametry do oceny bezpieczeństwa dekompresji. W badaniach przyżyciowych i autopsyjnych osób z wypadków nurkowych stwierdzano przypadki krwotoków, które nie powstały na skutek urazów czy też koincydencji innych jednostek chorobowych. Opisane przypadki nie zostały jednak wystarczająco wnikliwie zbadane pod kątem zaburzeń układu hemostazy. W artykule przedstawiono wyniki badań, których celem było określenie wpływu ekspozycji hiperbarycznych i dekompresji na wybrane parametry hemostazy. Badania zostały przeprowadzone u 39 zdrowych ochotników. 8 nurków poddano krótkotrwałej ekspozycji powietrznej odpowiadającej głębokości 30 m, 16 saturowanej ekspozycji powietrznej odpowiadającej głębokości 18 m oraz 15 saturowanej eksopzycji heliokosowej równej nurkowaniu na 30 m.
Introduction: Diving and decompression performed strictly according to the decompression tables, corrected by the Doppler assessment of desaturation process do not fully assure divers from the development of DCS or bone necrosis. Thus more sensitive and specific safety parameters of decompression have been still seeking. Haemorrhages are implicated in the pathogenesis of some cases of DCS without coincidence with trauma or other pathology. Bleeding complications occurring after diving reported in some papers has not been sufficiently investigated and thus could not be directly correlated to the enhanced fibrinolysis. The aim of our study was to measure the effect of hyperbaric expositions and decompression on the markers of hemostasis. Material and methods: 36 healthy divers underwent hyperbaric exposures. Divers were subjected to short term exposures to the pressure of 400 kPa (corresponding water depth - 30 m) with 24 min plateau and continuous decompression with air as a breathing medium (8 divers) or saturated exposures to the pressure of 200 kPa(corresponding water depth - 18 m) with air as a breathing medium (16 divers) or saturated exposures to the pressure of 400 kPa with heliox as a breathing medium (15 divers). The divers were monitored for Doppler-detected venous gas bubbles as a risk factor for DCS. Blood samples were taken before exposure and after decompression.

Opis:: Elevated concentration of homocysteine (Hcy) in human tissues, definied as hyperhomocysteinemia has been correlated with some diseases, such as cardiovascular, neurodegenerative, and kidney disorders. Homocysteine occurs in human blood plasma in several forms, including the most reactive one, the homocysteine thiolactone (HTL) - a cyclic thioester, which represents up to 0.29% of total plasma Hcy. In the article, the effects of hyperhomocysteinemia on the complex process of hemostasis, which regulates the flowing properties of blood, are described. Possible interactions of homocysteine and its different derivatives, including homocysteine thiolactone, with the major components of hemostasis such as endothelial cells, blood platelets, plasmatic fibrinogen and plasminogen, are also discussed. Modifications of hemostatic proteins (N-homocysteinylation or S-homocysteinylation) induced by Hcy or its thiolactone seem to be the main cause of homocysteine biotoxicity in hemostatic abnormalities. It is suggested that Hcy and HTL may also act as oxidants, but various polyphenolic antioxidants are able to inhibit the oxidative damage induced by Hcy or HTL. We also discuss the role of phenolic antioxidants in hyperhomocysteinemia -induced changes in hemostasis.

Opis:: The hemostasis system is designed to ensure the integrity of the body’s internal environment, stop bleeding, and maintain a liquid state of blood in the vascular channel. Modern biological and veterinary science presents highly fragmented and scarce data containing clinical and diagnostic clotting characteristics in different fish species. An essential point emphasising the practical component of such studies is spontaneous thrombus formation in fish farming described in the literature. The present research is devoted to the study of the functional state of plasma hemostasis in some ray-finned commercial fishes: phylogenetically more ancient cartilaginous ganoids - sturgeon Acipenser baerii and hybrid of sterlet A. ruthenus and starred sturgeon A. stellatus, as well as bony fishes - carp Cyprinus carpio and tilapia Oreochromis niloticus. It should be noted that the current study was performed at the aquaculture development center “AquaBioCenter” of VSDFA from 2015 to 2020. Species-specific features of clotting were revealed: activation by common and extrinsic pathways, characterised by thrombin time (TT), prothrombin time (PT), and fibrinogen concentration, is several times faster in cartilaginous ganoids than in both bony fish species; hemostasis with activation of the intrinsic pathway, characterised by activated partial thromboplastin time (APTT), is faster in hybrids and tilapias, in contrast to carps and sturgeons. Content of soluble fibrin monomer complexes (SFMC) in all fish was higher than in dogs and humans but lower than in cattle. The highest amount of SFMC was detected in carps, the lowest - in cartilaginous ganoids.
