    Opis:
    Primary extranodal sites of development of lymphoid neoplasms are rare and concern about 5% of patients with Hodgkin's lymphoma. Extranodal development is more common in non Hodgkin's lymphoma and may reach 33%.A 27-year-old woman was diagnosed by a cardiologist for a short breath. On the physical examination no other abnormalities were observed. Echocardiography, performed by cardiologist, revealed a large tumor, overlaying the right ventricle and compressing the pulmonary trunk. Chest X-ray, ultrasound and CT-scan confirmed diagnosis. In fine needle aspiration clear, lucid fluid was obtained. Scintygraphy of the neck and thorax showed accumulation of the marker in the properly placed but enlarged thyroid gland. Patient was qualified for surgical treatment - cervicotomy and sternothomy were performed. The histopatological exam of the tumor revealed Hodgkin's lymphoma of the mediastinum (classical subtype NS-1). Following the surgery, adjuvant therapy was instituted. After the treatment PET-CT-scan did not show any kind of non-physiological radiomarker's accumulation in the monitored regions of the body and in in three-years follow-up the patient shows no signs of recurrence.

    Opis:
    The aim of this study was to assess the course of the healing process following the use of dibutyrylchitin (DBC) dressing, a fully degradable material used in the treatment of ulcers which occur during chronic venous insufficiency common in patients suffering from type 2 diabetes. These diseases have a significant impact on the patients’ standard of living, including the potential employment, and on the declining attendance at the current workplace. The implementation of this innovative therapeutic solution may positively affect the above-mentioned difficulties. An analysis of the healing process, following the application of the DBC dressing, was performed. Once the dressing was positioned on the wound, the analysis indicated that it underwent a process of degradation facilitated by the enzymes occurring naturally in the wound. When fully degraded, a further layer was applied. This process was repeated until the wound was fully healed. The study group consisted of 4 patients previously diagnosed with type 2 diabetes. During the observation period, the ulcers in all 4 cases had healed. The examined wound dressings adhered well to the wound surface and degraded within it. No side effects or adverse effects of the applied innovative therapy were observed. An addition of the biodegradable DBC dressing to the standard therapy procedure of ulcers occurring during chronic venous insufficiency among patients with type 2 diabetes indicate safe and effective treatment, which may have a direct reflection in the patient’s professional capacity enhancement. It resulted in the complete healing of all ulcers in each of the observed cases.

    Opis:
    The coding sequences of two S-adenosyl-L-homocysteine hydrolases (SAHases) were identified in yellow lupine by screenig of a cDNA library. One of them, corresponding to the complete protein, was sequenced and compared with 52 other SAHase sequences. Phylogenetic analysis of these proteins identified three groups of the enzymes. Group A comprises only bacterial sequences. Group B is subdivided into two subgroups, one of which (B1) is formed by animal sequences. Subgroup B2 consist of two distinct clusters, B2a and B2b. Cluster B2b comprises all known plant sequences, including the yellow lupine enzyme, which are distinguished by a 50-residue insert. Group C is heterogeneous and contains SAHases from Archaea as well as a new class of animal enzymes, distinctly different from those in group B1.

    Opis:
    Background: Acute respiratory distress syndrome (ARDS) is a serious complication after cardiac surgery with a variety of clinical risk factors. It was hypothesized that genome variants predispose these patients to it. Material and methods: A cohort of 509 adult Caucasians undergoing on-pump cardiac surgery were observed for postoperative ARDS defined by the Berlin definition. Clinical variables and 10 single-nucleotide variants of genes involved in inflammatory pathways were analyzed for associations with four groups, defined by paO2/fiO2 (PF) ratio: 1) no ARDS (PF > 300 mmHg), 2) mild ARDS (200 < PF ≤ 300 mm Hg), 3) moderate ARDS (100 < PF ≤ 200 mm Hg), and 4) severe ARDS (PF ≤ 100 mmHg). Variables remaining in trends at p < 0.05 were considered significant. Results: The prevalence of ARDS was 7.9%. Only LBP1 rs2232582 remained in a genotypic trend with ARDS aggravation (p = 0.08). Clinical variables associated with ARDS aggravation: impaired left ventricular ejection fraction (p = 0.04), pulmonary hypertension (p = 0.01), intraoperative hypotension (p = 0.009), and postoperative day 1 white blood cell count (p = 0.015). More aggravated ARDS was associated with longer mechanical ventilation (p=0.01) and length of stay in ICU (p = 0.002). Conclusions: The borderline association with LBP1 rs2232582 and the identified risk factors suggest possible involvement of the LPS-LBP1 pathway in ARDS of the INFLACOR cohort.

    Opis:
    There is increasing evidence that genetic variability influences patients' early morbidity after cardiac surgery performed using cardiopulmonary bypass (CPB). The use of mortality as an outcome measure in cardiac surgical genetic association studies is rare. We publish the 30-day and 5-year survival analyses with focus on pre-, intra-, postoperative variables, biochemical parameters, and genetic variants in the INFLACOR (INFLAmmation in Cardiac OpeRations) cohort. In a prospectively recruited cohort of 518 adult Polish Caucasians, who underwent cardiac surgery in which CPB was used, the clinical data, biochemical parameters, IL-6, soluble ICAM-1, TNFα, soluble E-selectin, and 10 single nucleotide polymorphisms were evaluated for their association with 30-day and 5-year mortality. The 30-day mortality was associated with: pre-operative prothrombin international normalized ratio, intra-operative blood lactate, postoperative serum creatine phosphokinase, and acute kidney injury requiring renal replacement therapy (AKI-RRT) in logistic regression. Factors that determined the 5-year survival included: pre-operative NYHA class, history of peripheral artery disease and severe chronic obstructive pulmonary disease, intra-operative blood transfusion; and postoperative peripheral hypothermia, myocardial infarction, infection, and AKI-RRT in Cox regression. Serum levels of IL-6 and ICAM-1 measured three hours after the operation were associated with 30-day and 5-year mortality, respectively. The ICAM1 rs5498 was associated with 30-day and 5-year survival with borderline significance. Different risk factors determined the early (30-day) and late (5-year) survival after adult cardiac surgery in which cardiopulmonary bypass was used. Future genetic association studies in cardiac surgical patients should account for the identified chronic and perioperative risk factors.
