RESUMO

Several studies showed the role of trace elements in the increase in human susceptibility to cardiovascular diseases. Carotid artery stenosis is a leading cause of ischemic neurological events. We aimed to analyze the potential role of trace elements in hair as biomarkers of atherosclerotic carotid artery disease. Materials and Methods: Fifty-seven (n = 31 (54%) men and n = 26 (46%) women) individuals with a mean age of 67.7 ± 7.7 years who were white, European, non-Hispanic, and non-Latino were diagnosed and treated in hypertensiology/internal medicine and surgical departments over three consecutive months. Of these patients, forty were diagnosed with advanced carotid artery disease, and seventeen comprised a group of healthy controls. Inflammatory and oncological diseases were exclusion criteria. Hair samples were collected, and 14 trace elements were analyzed. Clinical and laboratory data were compared and revealed differences in the co-existence of diabetes (p = 0.036) and smoking history (p = 0.041). In the multivariable analysis, zinc, chrome, and copper revealed predictive value for the occurrence of carotid artery disease, and their combined receiver operating curve showed area under the curve of 0.935, with a sensitivity of 95% and a specificity of 82.4%. Conclusion: Our report shows the significance of trace elements analyses in patients with advanced carotid artery disease. We revealed that zinc, copper, and chrome concentrations are of particular importance in differentiating atherosclerotic disease and may serve as biomarkers of carotid atherosclerosis. Hair samples represent an easily obtained and beneficial biomatrix for the assessment of biomarkers.

RESUMO

BACKGROUND: Carotid artery stenosis is often considered a stable clinical condition, and the underlying atherosclerosis is thought to have an inflammatory background. OBJECTIVES: The aim of the study was to assess the value of different parameters obtained from whole blood counts for the prediction of advanced carotid artery atherosclerosis, including vessel occlusion, irrespective of symptom occurrence. MATERIAL AND METHODS: The study group comprised 290 patients (84 (29%) females and 206 (71%) males) with a mean age of 68 ±8 years, who were admitted to the Vascular Surgery Department due to significant carotid artery disease. Patients were retrospectively divided into 2 subgroups regarding the presence or absence of artery occlusion. The demographic, clinical and laboratory preoperative data were compared between both groups. RESULTS: We found significant differences in preoperative large unstained cell (LUC) counts between patients with and without carotid artery occlusion (p = 0.003), when analyzed with the Mann-Whitney test for independent samples. The receiver operating characteristic (ROC) curve showed that LUC count has prognostic properties for carotid artery occlusion, with an area under the curve (AUC) of 0.637 (p = 0.033), yielding a 69.70% sensitivity and a 51.75% specificity. CONCLUSIONS: Large unstained cells represent an acute inflammatory state related to artery occlusion. An LUC count below the cutoff value of 0.16×109/L may be a predictor of carotid artery occlusion. Therefore, carotid artery occlusion should not be regarded as a chronic state, but as a clinical challenge being promoted by active inflammatory processes.

RESUMO

<b><br>Introduction:</b> Chronic venous disease (CVD) is a rising problem in western countries. There are several stages of CVD that can be treated with different ways. One of the methods of treating varicosity, C2 stage of CVD, is still developing endovenous laser ablation (EVLA). This method is popular due to its short operation time, less bleeding, quick recovery and no surgical scars. The compression therapy in form of compression stockings has been widely used as a conservative treatment of early stage CVD and it's also used after EVLA. However there are no strong recommendations towards using compression therapy after this kind of surgery.</br> <b><br>Aim and Method:</b> This paper is aimed to review existing knowledge about compression therapy benefits and its recommended time period after EVLA. Search engines used in review: Pubmed and Cochrane.</br> <b><br>Results:</b> Studies focusing on the compression therapy after EVLA of varicose veins have questioned the prolonged use of compression therapy as it brings no additional benefits and might be difficult for patients to adhere. The existing studies recommended the time period no greater than 1-2 weeks. There are no significant changes in reoccurrence rate and return to normal activities between compression and non-compression group. It is proven that compression therapy significantly reduces the postoperative pain and consumption of analgesics.</br> <b><br>Discussion:</b> Compression therapy seems as a safe option for low pain management. There is a need for further research involving the impact of the compression therapy after EVLA, especially in group of low energy delivered settings as the results of treatment are promising.</br>.

RESUMO

The cellular response to hypoxia includes the expression of hypoxia-inducible factor-1 (HIF-1) and its target genes: vascular endothelial growth factor (VEGF) and CXC chemokine receptor 4 (CXCR4). The aim of this study was to investigate the expression and prognostic significance of VEGF and CXCR4, which are responsible for angiogenesis and progression in gastric cancer. Twenty-eight gastric cancer patients were analyzed. The mRNA expression was examined in primary tumors and corresponding normal gastric mucosa by RT-PCR. The protein level was examined by immunohistochemistry staining. The high expression of VEGF and CXCR4 was found in 71.0 and 64.0% of tumors, respectively. The mean levels of VEGF and CXCR4 were upregulated in primary tumors compared to normal mucosa (p = 0.0007, p = 0.0052). A correlation between VEGF expression and tumor invasion (p = 0.0216) and stage (p = 0.0181) was found. CXCR4 expression correlated with lymph node metastases (p = 0.0237) and stage (p = 0.0054). The VEGF expression correlated with microvessel density (MVD) (p = 0.0491). The overall 3-year survival rate was 46.4% and correlated negatively with high CXCR4 mRNA expression (p = 0.0089). VEGF and CXCR4 play an important role in tumor progression. Their overexpression correlates with a bad prognosis and may improve high-risk patient selection, and these patients may obtain additional survival benefits if treated more aggressively.

RESUMO

INTRODUCTION: Surgical treatment is always associated with tissue damage and the subsequent development of oxidative stress. AIM: To compare the oxidative stress response in patients treated operatively for inguinal hernia with multi-trocar laparoscopic totally extraperitoneal technique (TEP) or single-incision laparoscopic totally extraperitoneal technique (TEP-SI). MATERIAL AND METHODS: A randomized group of 34 patients with one-sided inguinal hernia was enrolled in the study. Seventeen patients were treated with a standard TEP method (group 1) and the other 17 patients were treated with the TEP-SI technique (group 2). Thiobarbituric acid reactive substances (TBARS) and total antioxidant status (TAS) as the oxidative stress markers were measured before surgery (0), 1 day (1) and 4 days (2) after surgery. RESULTS: A decrease in TAS on the first day after surgery was observed in both groups. Sustained reduction on the fourth day after surgery was observed in group 1, whereas in group 2 an increase followed. A statistically significant difference was observed in TAS (2 : 0) ratio with a meaningful decrease in group 1. TBARS concentration was elevated 1 day after surgery in both groups. It remained at an elevated level on the fourth day after surgery in group 1, while it decreased in group 2. The duration of surgery was higher in group 2 (mean: 57.5 min) than in group 1 (mean: 50.0 min) (p = 0.0286). CONCLUSIONS: Oxidative stress levels are lower in patients treated operatively by TEP-SI technique than by TEP. TEP-SI may be considered as a less invasive technique associated with less tissue injury.

RESUMO

AKI is one of the most common underdiagnosed postoperative complications that can occur after any type of surgery. Contrast-induced nephropathy (CIN) is still poorly defined and due a wide range of confounding individual variables, its risk is difficult to determine. CIN mainly affects patients with underlying chronic kidney disease, diabetes, sepsis, heart failure, acute coronary syndrome and cardiogenic shock. Further research is necessary to better understand pathophysiology of contrast-induced AKI and consequent implementation of effective prevention and therapeutic strategies. Although many therapies have been tested to avoid CIN, the only potent preventative strategy involves aggressive fluid administration and reduction of contrast volume. Regardless of surgical technique-open or endovascular-perioperative AKI is associated with significant morbidity, mortality and cost. Endovascular procedures always require administration of a contrast media, which may cause acute tubular necrosis or renal vascular embolization leading to renal ischemia and as a consequence, contribute to increased number of post-operative AKIs.

RESUMO

Neovascularization and angiogenesis are vital processes in the repair of damaged tissue, creating new blood vessel networks and increasing oxygen and nutrient supply for regeneration. The importance of Adipose-derived Mesenchymal Stem Cells (ASCs) contained in the adipose tissue surrounding blood vessel networks to these processes remains unknown and the exact mechanisms responsible for directing adipogenic cell fate remain to be discovered. As adipose tissue contains a heterogenous population of partially differentiated cells of adipocyte lineage; tissue repair, angiogenesis and neovascularization may be closely linked to the function of ASCs in a complex relationship. This review aims to investigate the link between ASCs and angiogenesis/neovascularization, with references to current studies. The molecular mechanisms of these processes, as well as ASC differentiation and proliferation are described in detail. ASCs may differentiate into endothelial cells during neovascularization; however, recent clinical trials have suggested that ASCs may also stimulate angiogenesis and neovascularization indirectly through the release of paracrine factors.

RESUMO

In the current case report we present a novel case of a successful coil embolization of the left internal carotid artery aneurysm. The patient presented with neck pain and a palpable pulsating tumor and was admitted to the vascular surgery clinic where an angio-CT scan of the neck was performed. Angio-CT revealed a left internal carotid artery aneurysm with a narrow neck. The patient was admitted to the department of vascular surgery where she was enrolled into endovascular coil embolization. After the procedure, control angiography showed complete embolization of the aneurysm. Three months following the procedure, doppler ultrasonography of the carotid arteries showed no demonstrable flow into the aneurysm. Six months following the procedure, angio-CT confirmed complete aneurysm thrombosis. Based on this case, endovascular coil embolization of the carotid artery aneurysms is a safe and effective method of treatment.

RESUMO

OBJECTIVES: The purpose of this study is to report the intravascular ultrasound morphometry of iliac veins and its relation to demographic and anthropometric factors in subjects without chronic venous insufficiency. METHODS: Thirty-three patients, without chronic venous insufficiency - qualified to great saphenous vein stripping due to unilateral, primary varicose veins - participated in the study. During the surgery, left and right external iliac veins, common iliac veins and inferior vena cava were interrogated with intravascular ultrasound. The morphometric analysis included measurement of a cross-sectional area at normal, non-stenosed vein segments (ref-CSA) and at the point of the most prominent narrowing (minimal lumen area (MLA)). Based on these measurements, a percentage of stenosis (S%) and calculated lumen diameter of interrogated veins were determined according to the following formulas, S% = (ref-CSA-MLA)/ref-CSA × 100 and CLD = 2 × âˆš(ref-CSA/π), respectively. RESULTS: Median ref-CSA, S% and calculated lumen diameter were 265.3 mm2, 45.8% and 18.4 mm for inferior vena cava; 193.9 mm2, 62.4% and 15.7 mm for left common iliac veins; 166.9 mm2, 35.7% and 14.2 mm for right common iliac veins; 136.5 mm2, 48.0% and 12.8 mm for left external iliac veins and 140.9 mm2, 46.3% and 13.5 mm for right external iliac veins. There were statistically significant differences between left and right common iliac veins ref-CSA, common iliac veins S% and common iliac veins calculated lumen diameter (p = 0.03, p < 0 and p = 0.03, respectively). The S% of left external iliac veins was greater in women 52.2 versus 37.2% in men (p = 0.04). Neither age nor anthropometric factors had any influence on the calculated lumen diameter of the analysed veins. A negative correlation between the left common iliac veins S% and the age was observed (p = 0.03). CONCLUSIONS: In adult subjects, the calculated lumen diameter of the common iliac veins is greater on the left side and is not influenced by age and body size. Common iliac vein stenosis occurs more frequently on the left side, decreases with age and tends to be more frequent in women.

RESUMO

Lately there are many new, promising low-density lipoprotein cholesterol reducing therapies with PCSK9 inhibitors. We performed selected sampling of the publications in PubMed and made a review according to selected keywords. It summarizes the effect of PCSK9 on vascular aging, directly associated with lipid and glucose metabolism, chronic inflammation, atherosclerosis and hypertension. Serum level of PCSK9 is different in patients affected by certain illnesses (whose risk increases with age) than in healthy individuals. The same could be observed in the case of chronic inflammation. In this review we summarize what is known about the role PCSK9 in human metabolism and how this could affect the vascular aging process. Based on the available sources, we prove that PCSK9 is involved in many biochemical pathways associated with vascular aging. In the future, treatments using PCSK9 inhibition may not only reduce the cardiovascular risk but also slow down this process.

RESUMO

BACKGROUND: In recent years, a rapid increase in studies focusing on the role of oxidative stress in the pathogenesis of an abdominal aortic aneurysm (AAA) has been observed. Oxidative modifications of proteins are infrequently evaluated in reference to AAA. OBJECTIVES: The intensity of oxidative protein modifications, presented as advanced oxidation protein products (AOPP) and carbonylated proteins (C=O), in AAA patients qualified for surgery was estimated. The effect of surgical techniques and intraoperative and postoperative treatment on AOPP and C=O levels was evaluated. PATIENTS: The EVAR group, consisting of 30 patients, was classified for endovascular aneurysm repair, whereas 28 patients were classified for conventional open repair (OR). METHODS: AOPP and C=O were measured using a colorimetric assay kit. RESULTS: A significantly lower AOPP level obtained 2-4 days after EVAR surgery in comparison with the value found before surgery was noted. In the case of OR postoperative treatment, a tendency of AOPP level to increase was observed. The tendency of C=O to decrease after surgery in the EVAR group was indicated. However, the C=O level tended to increase after OR surgery and reached a significantly higher value 5-7 days after surgery compared with the value obtained before surgery. CONCLUSIONS: Based on our results, it may be concluded that AAA as well as surgical technique contribute to the formation of AOPP and C=O. The analysis of changes in AOPP and C=O values obtained after surgery revealed a significant effect of a patient's condition before surgery as well as the choice of surgery technique on the values of the studied parameters revealed during postoperative treatment.

RESUMO

Wlodarczyk, M, Kusy, K, Slominska, E, Krasinski, Z, and Zielinski, J. Changes in blood concentration of adenosine triphosphate metabolism biomarkers during incremental exercise in highly trained athletes of different sport specializations. J Strength Cond Res 33(5): 1192-1200, 2019-We hypothesized that (a) high-level specialized sport training causes different adaptations that induce specific biomarker release dynamics during exercise and recovery and (b) skeletal muscle mass affects biomarker release. Eleven sprinters (21-30 years), 16 endurance runners (18-31 years), 12 futsal players (18-29 years), and 12 amateur runners as controls (22-33 years) were examined. Hypoxanthine (Hx), xanthine (X), uric acid (UA), ammonia (NH3), and lactate (LA) concentrations were determined at rest, during an incremental treadmill exercise test (every 3 minutes), and during recovery (5, 10, 15, 20, and 30 minutes after exercise). Hx, X, and UA concentration was determined from plasma, while LA and NH3 from whole blood, and muscle mass was assessed using dual X-ray absorptiometry method. At rest, during incremental exercise, and up to 30 minutes into the postexercise recovery period, sprinters had lowest Hx, X, and UA concentrations, and endurance athletes had lowest NH3 concentrations. For LA during exercise, the lowest concentrations were noted in endurance athletes, except when reaching maximum intensity, where the differences between groups were not significant. There were no significant correlations observed between skeletal muscle mass and biomarker concentration at maximal intensity and recovery in any group. In conclusion, the magnitude of exercise-induced biomarker concentration is only related to training adaptations through specific training profile but not to muscle mass. In addition, the results suggest that combined measuring of LA, NH3, and Hx concentration in blood is useful in indirectly reflecting key changes in exercise- and training-induced energy status. Further research should focus on studying how specific training sessions affect individual biomarker response in highly trained athletes.

RESUMO

BACKGROUND AND AIM: The timing of P2Y12 inhibitor loading in patients undergoing percutaneous coronary intervention (PCI) is a matter of debate. The aim of our study was to compare the efficacy and safety of oral P2Y12 inhibitors: clopidogrel, ticagrelor and prasugrel administered at two different time points in relation to PCI: early (> 2 hours pre-PCI) versus late (< 2 hours pre-PCI or post-PCI). METHODS: This is a systematic review and meta-analysis. Randomized controlled trials and non-randomized studies were included. Outcomes evaluated were combined major adverse cardiovascular events (MACEs), myocardial infarction (MI), target vessel revascularization, death and bleeding complications. Summary estimates of the relative risks with therapy were calculated. RESULTS: Twenty-three studies met the selection criteria and included 60,907 patients. Early P2Y12 inhibitor loading was associated with a 22% relative risk reduction (RRR) of MACE (95% confidence interval [CI] = 0.68-0.89; p < 0.001). Early clopidogrel loading was associated with a 25% RRR of MACE (95% CI = 0.65-0.85; p < 0.001), a 30% RRR of MI (95% CI = 0.6-0.82; p < 0.0001) and 25% RRR of death (95% CI = 0.64-0.87; p = 0.0002), without an impact on major bleedings. In ST-elevation myocardial infarction as well as non-ST elevation acute coronary syndrome (NSTE-ACS), early clopidogrel loading resulted in 35 and 22% RRR in 30 days MACE (p < 0.001), respectively, with no impact in elective PCI. Whereas early loading with prasugrel and ticagrelor did not improve ischaemic outcomes, prasugrel administered early increased bleeding risks in NSTE-ACS. CONCLUSION: Early clopidogrel loading is associated with a better efficacy and similar safety, whereas timing of ticagrelor or prasugrel loading had no effects on ischaemic events.

RESUMO

This publication is a summary of the multidirectional effects of aspirin and its role in modern medicine. The history of aspirin, or acetylsalicylic acid (ASA), and its use dates back to ancient times, although the substance in its pure form has been produced and sold since 1899. Initially it was used for its antipyretic, analgesic, and anti-inflammatory effects. Over the years many other benefits associated with the administration of ASA have been revealed. The mechanism of aspirin's action was discovered thanks to the British pharmacologist and Nobel Prize winner Sir John Vane. Understanding the effects of acetylsalicylic acid, associated with the inhibition of cyclooxygenase and proinflammatory thromboxane A2 and with increased concentration of vasoprotective, antithrombotic prostacyclin, gave rise to the era of using small "cardiac" doses of ASA in cardiovascular diseases. In addition to the well-researched antiplatelet effect, other properties of ASA have been discovered, such as the non-COX-1 dependent improvement of endothelial function or the hypotensive effect after evening administration. According to the currently available knowledge, it is possible to speak of a pleiotropic effect of ASA and its use in the prevention of cardiovascular diseases, taking into account its anti-aggregation effect, circadian rhythms, and the principles of chronotherapy.

RESUMO

The utility in clinical practice of a recently developed and validated predictive model for venous thromboembolism (VTE) events in lymphoma patients, known as the thrombosis lymphoma (ThroLy) score, is unknown. We evaluated the association of ThroLy with VTE in patients treated for diffuse large B-cell lymphoma (DLBCL) or Hodgkin lymphoma (HL) undergoing ambulatory first-line chemotherapy. Retrospective analyses were performed on 428 patients (median age 50), 241 were newly diagnosed DLBCL, and 187 had HL. During initial chemotherapy, 64 (15%) patients developed VTE. According to the ThroLy, 322 (75.2%) patients were considered low risk, 88 (20.6%) patients had intermediate risk and 18 (4.2%) patients high risk for VTE development. Patients with DLBCL were more often in the high-risk ThroLy group and had more VTE events than HL. VTE occurred in; 38.9% (n = 7) high-risk patients, 29.5% (n = 26) intermediate risk, and 9.6% (n = 31) low risk according to the ThroLy score. However, in multivariate analysis, high ThroLy (OR 5.13; 95% CI: 1.83-14.36, P = .002), intermediate ThroLy (OR 3.96; 95% CI: 2.19-7.17, P < .001), and aggressive lymphoma-DLBCL (OR 1.91; 95% CI: 1.05-3.47, P = .034) were all significantly associated with development of VTE, 48% of the VTE events occurred in the low-risk ThroLy score group (the ROC AUC (95% CI) 0.40-0.70 and C statistic-0.55). In our study, the ThroLy score was not a suitably accurate model for predicting VTE events in patients at higher risk of VTE. Further research should be conducted to identify new biomarkers that will predict these events and to establish a new VTE risk assessment model.

RESUMO

Here we compared effect of serum from varicose patients undergoing endovenous laser ablation (EVLA) and classic vein stripping (CVS) on biological properties of endothelial cells and on the local and systemic profiles of proinflammatory agents. Results showed that serum from EVLA patients improved proliferation and reduced senescence and oxidative stress in the endothelial cells, as compared with the serum from CVS patients. These effects were related to a suppressed activity of TGF-ß1, the level of which in the serum from the EVLA patients was decreased. Medium generated by the cells subjected to EVLA serum contained decreased amounts of ICAM-1, VCAM-1, and E-selectin and increased amount of uPA, whereas the serum itself contained decreased concentrations of ICAM-1, E-selectin, and P-selectin and increased concentrations of uPA, PAI-1, and TFPI. Both EVLA and CVS resulted in diversified patients' reaction with respect to a direction of postprocedure changes in proinflammatory factors' serum level. Analysis of proportions showed that the groups differed remarkably in case of ICAM-1 and ET-1, the level of which declined in a higher fraction of patients treated endovenously. Our findings indicate that EVLA preserves better than CVS the functionality of vascular endothelium and modulates better both local and systemic profile of proinflammatory mediators.

RESUMO

INTRODUCTION: Arterial hypertension (HT) is one of the most common diseases around the world and constitutes a significant medical, social, and economic problem. Lifestyle changes, including adequate fruit and vegetable consumption, play an important role in controlling blood pressure (BP) and other cardiovascular risk factors. AIM: To compare the influence of adding acetylsalicylic acid (ASA) or standardized tomato extract (STE) to standard hypotensive therapy on the values of arterial pressure and the daily blood pressure profiles of patients with hypertension and high cardiovascular risk. MATERIAL AND METHODS: The study included 65 patients with arterial hypertension and high cardiovascular risk. High-risk patients with primary hypertension were randomly allocated in a blinded fashion to one of two groups (ASA or STE). In each case, two visits were made: the first - before the treatment, and the second - after 4 weeks of treatment. During each visit, the patients underwent a clinical measurement of arterial pressure and an ambulatory blood pressure measurement (ABPM). Blood platelet aggregation was assessed using the VerifyNow analyzer. RESULTS: After 4 weeks of treatment, the blood pressure values during the day (p < 0.001), during the night (p < 0.05), and in 24-h BP profiles (p < 0.01) obtained with ABPM were significantly lower in the STE group in comparison to the ASA group. The addition of STE to standard hypotensive treatment resulted in a favorable increase in the nocturnal fall of diastolic blood pressure (DBP) (by 6.5%) and mean arterial pressure (MAP) (by 3.3%). CONCLUSIONS: The use of STE is significant in HT patients with high total cardiovascular risk; it is associated with better BP control and improvements in the daily BP profile.

RESUMO

A close causal relationship between cancer and venous thrombosis gives rise to questions about the effect of treatment modalities, in particular of the administered drugs, in patients with cancer-related venous thrombosis. An increased risk of chemotherapy-associated venous thromboembolism (VTE) has been well documented, while the effect of heparins used in VTE treatment on the disease course and prognosis in cancer patients has not been fully elucidated. This paper discusses the outcomes of the studies conducted so far investigating the role of heparins, in particular, low-molecular-weight heparins (LMWHs), in the prevention of thrombosis in cancer patients. It also focuses on such aspects of the treatment for cancer-associated VTE as treatment duration and drugs used. The paper summarizes the often discrepant results of long-term therapies with various LMWH products, emphasising that in this specific case the class effect is rather unlikely. It also presents the possible effects of heparins administered as part of cancer treatment, and points to the effects of LMWHs on cancer that are not related to an antithrombotic effect. On the 100th anniversary of heparin discovery, it can be said that heparin is irreversibly connected with thrombosis in the course of cancer.
