    Opis:
    Abnormal vitamin K status was documented in patients with chronic kidney diseases (CKD), especially those undergoing hemodialysis. The data related to patients undergoing peritoneal dialysis (PD) are contradictory. Therefore, in the present study we aimed to evaluate vitamin K status in patients with CKD who are treated with continuous ambulatory PD. Twenty-eight patients entered into the study. Dialysis vintage ranged from 3 to 89 months. Vitamin K status was assessed in all subjects using undercarboxylated prothrombin measurement (PIVKA-II). In addition, total protein and albumin levels, total cholesterol, LDL cholesterol, triglyceride, calcium, urea and creatinine concentrations were determined. PIVKA-II concentrations were abnormal in 13 (46.4 %) subjects. BMI values, both total and LDL cholesterol concentrations were significantly higher in patients with than those without vitamin K deficiency. Moreover, PIVKA II levels correlated with BMI values (r = 0.441, p < 0.019), LDL cholesterol (r = 0.434, p < 0.021) and creatinine (r = 0.406, p < 0.032) concentrations. However, through the use of logistic regression analysis and multiple regression analysis, no clinical factor was documented to be the independent risk factor of vitamin K deficiency. In conclusion, vitamin K deficiency is a frequent condition in peritoneally dialyzed patients. Assessment of vitamin K status should become a standard procedure in this group of patients.

    Opis:
    In this study, the vitamin K1 (phylloquinone) and vitamin K2 (menaquinone) contents of a selected range of cheeses were measured by high-performance liquid chromatography (HPLC) and compared with the fat content, maturation time and origin of the cheeses. In our study, the highest vitamin K2 content was recorded in Gouda (678.12 ng/g), Edam (712.70 ng/g) and Emmentaler (733.10 ng/g) cheeses with comparable levels of vitamin K1 in the analysed products (31.60 ng/g, 34.63 ng/g and 24.35 ng/g, respectively) and fat content (27%, 28% and 30%, respectively), as well as in Gouda cheese with a fat content of 48% after 48 weeks of maturation (756.50 ng/g). The fat content of the cheese was a factor that influenced the vitamin K content, with products with lower fat content having lower total vitamin K content compared to the other products analysed. Given the reports that poor vitamin K status is one of the risk factors for cardiovascular disease in the absence of conclusive evidence of adverse cardiovascular effects of dairy fats, cheese should be considered as an important dietary component for those concerned about heart health.
    W tym badaniu oznaczono zawartość witaminy K1 (filochinonu) i witaminy K2 (menachinonu) w wybranej gamie serów metodą wysokosprawnej chromatografii cieczowej (HPLC) i porównano z zawartością tłuszczu, czasem dojrzewania i pochodzeniem serów. W badaniach własnych największą zawartość witaminy K2 odnotowano w serach Gouda (678,12 ng/g), Edam (712,70 ng/g) i Emmentaler (733,10 ng/g) przy porównywalnych poziomach witaminy K1 w analizowanych produktach (odpowiednio 31,60 ng/g, 34,63 ng/g i 24,35 ng/g) i zawartości tłuszczu (odpowiednio 27%, 28% i 30%), jak również w serze Gouda o zawartości tłuszczu 48% po 48 tygodniach dojrzewania (756.50 ng/g). Zawartość tłuszczu w serze była czynnikiem, który wpływał na zawartość witaminy K, przy czym produkty o niższej zawartości tłuszczu miały niższą całkowitą zawartość witaminy K w porównaniu z pozostałymi analizowanymi produktami. Biorąc pod uwagę doniesienia, że słaby status witaminy K jest jednym z czynników ryzyka chorób sercowo-naczyniowych przy braku jednoznacznych dowodów na niekorzystny wpływ tłuszczów mlecznych na układ krążenia, sery powinny być traktowane jako ważny składnik diety osób, które dbają o zdrowie serca.

    Opis:
    The aim of the study was to determine whether patients treated with anticoagulants in the perioperative period are at higher risk of developing bleeding complications. Material and methods. Medical records of patients operated for abdominal hernia were analysed. Data concerning demographic characteristic of a group, type of hernia, comorbidities, preoperative anticoagulation therapy and complications were collected. Association of applied anticoagulation therapy with the time of drainage, the amount of drained discharge and the length of hospitalisation was evaluated. Results. Analysed group consisted of 186 patients. Thirty seven patients were treated with different schemes of anticoagulant therapy before the the surgery. Patients treated with triple anticoagulation therapy (acetylsalicylic acid, low-molecular weight heparin, vitamin K antagonists) had significantly longer time of drainage in comparison to patients treated according to other schemes (p<0.05). The amount of drained discharge and time of hospitalisation did not differ significantly. Neither comorbidities nor the administration of low-molecular weight heparin did not affect the analysed parameters. Conclusions. Patients operated on abdominal hernia, who were treated with triple anticoagulation therapy in peri-operative period, require significantly longer drainage of the wound what can result in prolonged hospitalisation

    Opis:
    Acute pulmonary embolism (APE) is one of the main causes of cardiovascular deaths and anticoagulant treatment plays a key role in preventing recurrent episodes, chronic thromboembolic pulmonary hypertension (CTEPH), and deaths. The aim of this study is to assess the real-life trends and to determine factors associated with the choice of anticoagulation therapy in patients with APE. This is a single center prospective open study. We followed 178 consecutive patients admitted to the tertiary clinical center with APE proven with computed tomography (CT) scan within period of 24 months. A total number of 178 patients with APE were enrolled in the study. 48.9% of subjects were hospitalized in cardiology department. As a prolonged anticoagulant therapy 35.7% of study cohort received direct oral anticoagulants (DOACs), 35.1% LMWH, and 29.2% vitamin K antagonists (VKA), respectively. No statistically significant differences were found between the departments regarding frequency of prescribing anticoagulants (p=0.15). The multivariable analysis showed that oral anti-coagulants (OACs) were less likely to be prescribed than LMWH in patients with malignancy, history of major bleeding, serious medical condition and altered mental status. OACs were preferred over LMWH in symptoms of deep vein thrombosis (DVT). VKA were significantly less likely to be chosen than DOACs in patients with history of orthopaedics procedure. After six months anticoagulation therapy was discontinued in 24.3% of patients. Concluding, the form of anticoagulant therapy was associated with the presence of chronic diseases. LMWH was prescribed in high bleeding risk patients more frequently.

    Opis:
    Synthetic analogs of vitamin D for potential use in differentiation therapy should selectively regulate genes necessary for differentiation without inducing any perturbations in calcium homeostasis. PRI-1906, an analog of vitamin D2, and PRI-2191, an analog of vitamin D3 bind nuclear vitamin D receptor (nVDR) with substantially lower affinity than 1,25-dihydroxyvitamin D3 (1,25-D3), but have higher differentiation-inducing activity as estimated in HL-60 leukemia cell model. To examine how their increased differentiation-inducing activity is regulated we tested the hypothesis that membrane-mediated events, unrelated to nVDR, take part in the differentiation in response to PRI-1906 and PRI-2191. The induction of leukemia cell differentiation in response to the analogs of vitamin D was inhibited by LY294002 (phosphatidylinositol 3-kinase inhibitor), PD98059 (inhibitor of MEK1,2, an upstream regulator of extracellular-signal regulated kinase) and rapamycin (p70S6K inhibitor) pointing out that activation of signal transduction pathways unrelated to nVDR is necessary for differentiation. On the other hand, inhibition of cytosolic phospholipase A2 accelerated the differentiation of HL-60 cells induced by either 1,25-D3 or by the vitamin D analogs suggesting possible existence of a feedback loop between extracellular-signal regulated kinases and phospholipase A2.
