Abstract
Background. Chronic inflammation is considered to be involved in the development of CVD. It is important to find a simple test that enables the identification of patients at risk and that may be used in primary care. The aim of this study is to investigate the associations of high-sensitivity C-reactive protein (hsCRP) with selected factors—age, gender, obesity, dyslipidemia, diabetes, hyperuricemia, vitamin D-25(OH)D, cardiovascular diseases (CVD), coronary heart disease, cerebrovascular disease, and hypertension. Results. Statistically significant correlations were found between hsCRP and the following: age (rs = 0.304, p = 0.0000); gender (female) (p = 0.0173); BMI (rs = 0.295, p = 0.0001); waist circumference (rs = 0.250, p = 0.0007); dyslipidemia (p = 0.0159); glycemia (rs = 0.173, p = 0.0207); and significant negative correlations between hsCRP and 25(OH)D (rs = −0.203, p = 0.0065). In patients with CVD, hypertension, diabetes, or visceral obesity, hsCRP was significantly higher than in the subgroup without these disorders. There was a statistically significant relationship between hsCRP and the number of the metabolic syndrome elements (p = 0.0053). Conclusions. The hsCRP test seem to be a simple test that may be used at the primary care level to identify patients at risk of metabolic disorders, CVD, and hypertension. Vitamin D concentration may be a determining factor of systemic inflammation (it may have a modulating effect).

Abstract
Prostate cancer is the second most common cancer affecting the male population all over the world. The existence of a correlation between lipid metabolism disorders and cancer of the prostate gland has been widely known for a long time. According to hypotheses, cholesterol may contribute to prostate cancer progression as a result of its participation as a signaling molecule in prostate growth and differentiation via numerous biologic mechanisms including Akt signaling and de novo steroidogenesis. The results of some studies suggest that increased cholesterol levels may be associated with a higher risk of a more aggressive course of the disease. The aforementioned alterations in the synthesis of fatty acids are a unique feature of cancer and, therefore, constitute an attractive target for therapeutic intervention in the treatment of prostate cancer. Pharmacological or gene therapy aims to reduce the activity of enzymes involved in de novo synthesis of fatty acids, FASN, ACLY (ATP citrate lyase) or SCD-1 (Stearoyl-CoA Desaturase) in particular, that may result in cells growth arrest. Nevertheless, not all cancers are unequivocally associated with hypocholesterolaemia. It cannot be ruled out that the relationship between prostate cancer and lipid disorders is not a direct quantitative correlation between carcinogenesis and the amount of circulating cholesterol. Perhaps the correspondence is more sophisticated and connected to the distribution of cholesterol fractions or even sub-fractions of e.g. HDL cholesterol.

Int J Mol Sci 2021; 22:ijms22094618. [PMID: 33924827 PMCID: PMC8125622 DOI: 10.3390/ijms22094618] [Citation(s) in RCA: 20] [Impact Index Per Article: 6.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2021] [Revised: 04/18/2021] [Accepted: 04/22/2021] [Indexed: 12/12/2022] Open
Abstract
Acute kidney injury is a common complication of many medical procedures, including those used in cancer treatment. Both chemotherapy and immunotherapy may result in deterioration of kidney function, which may lead to an increase in mortality among patients with cancer. Antineoplastic agents can affect any element of the nephron, leading to the appearance of clinical symptoms such as proteinuria, hypertension, electrolyte disorders, glomerulonephritis, acute and chronic interstitial nephritis and acute kidney injury. The medical literature describing renal complications occurring during chemotherapeutic and immunotherapeutic treatment in neoplasms, such as colorectal cancer, non-small cell lung cancer and melanoma, was analysed. The immune system plays an important role in controlling the development of neoplasms and fighting them. Oncological treatment algorithms include immunotherapy as monotherapy, combined with chemotherapy or chemotherapy as monotherapy. In the treatment of the above-mentioned neoplasms immunotherapeutics are used, such as checkpoint inhibitors (CPI) (i.e., ipilimumab, pembrolizumab, nivolumab, atezolizumab), vascular endothelial growth factor (VEGF) inhibitors (i.e., bevacizumab, ramucirumab) and a variety of chemotherapeutic agents (irinotecan, capecitabine, oxaliplatin, gefitinib, erlotinib, gemcitabine, cisplatin, paclitaxel, carboplatin, doclitaxel, vinorelbine, topotecan, etoposide). In our article, we focused on the number and type of renal complications as well as on the time of their manifestation when using specific treatment regimens. Our analysis also includes case reports. We discussed treatment of immunological complications and adjustments of the dose of chemotherapeutic agents depending on the creatinine clearance. Analysing the data from the literature, when two immunotherapeutic agents are used together, the number of recorded renal complications increases. Bevacizumab and ramucirumab are the cause of the largest number of renal complications among the immunotherapeutic agents described above. Cisplatin is the best-described substance with the greatest nephrotoxic potential among the chemotherapeutic agents. Crucial for renal complications are also cancer stage, previous chemotherapy and other risk factors of AKI such as age, comorbidities and medications used. Due to the described complications during oncological treatment, including kidney damage, it seems necessary to elaborate standards of cooperation between oncologists and nephrologists both during and after treatment of a patient with cancer. Therefore, it is necessary to conduct further research and develop algorithms for management of a cancer patient, especially during such an intensive progress in oncology.

Abstract
For many years clinicians have been searching for "kidney troponin"- a simple diagnostic tool to assess the risk of acute kidney injury (AKI). Recently, the rise in the variety of contrast-related procedures (contrast computed tomography (CT), percutaneous coronary intervention (PCI) and angiography) has resulted in the increased number of contrast-induced acute kidney injuries (CI-AKI). CIAKI remains an important cause of overall mortality, prolonged hospitalisation and it increases the total costs of therapy. The consequences of kidney dysfunction affect the quality of life and they may lead to disability as well. Despite extensive worldwide research, there are no sensitive and reliable methods of CI-AKI prediction. Kidney Injury Molecule 1 (KIM-1) and Neutrophil Gelatinase Lipocalin (NGAL) have been considered as kidney-specific molecules. High concentrations of these substances before the implementation of contrast-related procedures have been suggested to enable the estimation of kidney vulnerability to CI-AKI and they seem to have the predictive potential for cardiovascular events and overall mortality. According to other authors, routine determination of known inflammation factors (e.g., CRP, WBC, and neutrophil count) may be helpful in the prediction of CIAKI. However, the results of clinical trials provide contrasting results. The pathomechanism of contrast- induced nephropathy remains unclear. Due to its prevalence, the evaluation of the risk of acute kidney injury remains a serious problem to be solved. This paper reviews pathophysiology and suggested optimal markers facilitating the prediction of contrast-induced acute kidney injury.

Abstract
Numerous studies have indicated that the progression of chronic kidney disease (CKD) to end-stage renal disease (ESRD) is strictly associated with the accumulation of toxic metabolites in blood and other metabolic compartments. This accumulation was suggested to be related to enhanced generation of toxins from the dysbiotic microbiome accompanied by their reduced elimination by impaired kidneys. Intestinal microbiota play a key role in the accumulation of uremic toxins due to the fact that numerous uremic solutes are generated in the process of protein fermentation by colonic microbiota. Some disease states, including CKD, are associated with the presence of dysbiosis, which can be defined as an "imbalanced intestinal microbial community with quantitative and qualitative changes in the composition and metabolic activities of the gut microbiota". The results of studies have confirmed the altered composition and functions of gut microbial community in chronic kidney disease. In the course of CKD protein-bound uremic toxins, including indoxyl sulfate, p-cresyl glucuronide, p-cresyl sulfate and indole-3-acetic acid are progressively accumulated. The presence of chronic kidney disease may be accompanied by the development of intestinal inflammation and epithelial barrier impairment leading to hastened systemic translocation of bacterial-derived uremic toxins and consequent oxidative stress injury to the kidney, cardiovascular and endocrine systems. These findings offer new therapeutic possibilities for the management of uremia, inflammation and kidney disease progression and the prevention of adverse outcomes in CKD patients. It seems that dietary interventions comprising prebiotics, probiotics, and synbiotics could pose a promising strategy in the management of uremic toxins in CKD.

Abstract
Chronic kidney disease (CKD) is a worldwide health problem in which prevalence is constantly rising. The pathophysiology of CKD is complicated and has not been fully resolved. However, elevated oxidative stress is considered to play a vital role in the development of this disease. CKD is also thought to be an inflammatory disorder in which uremic toxins participate in the development of the inflammatory milieu. A healthy, balanced diet supports the maintenance of a good health status as it helps to reduce the risk of the development of chronic diseases, including chronic kidney disease, diabetes mellitus, and hypertension. Numerous studies have demonstrated that functional molecules and nutrients, including fatty acids and fiber as well as nutraceuticals such as curcumin, steviol glycosides, and resveratrol not only exert beneficial effects on pro-inflammatory and anti-inflammatory pathways but also on gut mucosa. Nutraceuticals have attracted great interest recently due to their potential favorable physiological effects on the human body and their safety. This review presents some nutraceuticals in which consumption could exert a beneficial impact on the development and progression of renal disease as well cardiovascular disease.

Abstract
INTRODUCTION Diabetes mellitus (DM) due to its increasing prevalence and associated morbidity and mortality has become a serious public health problem. In DM, HDL may lose its beneficial features and become proatherogenic due to its altered biological activity thus increasing cardiovascular risk. The aim of this study was to assess the influence of the presence of diabetes mellitus type 2 and its duration on the distribution of HDL subfractions. Moreover, the effect of statin treatment on HDL subfraction share was analysed in this study. METHODS The study group consisted of 50 patients with newly diagnosed DM and 50 persons with DM for longer than 10 years while the control group consisted of 50 healthy volunteers. HDL subfractions were analysed with the use of Lipoprint. RESULTS We demonstrated progressive worsening of heart functioning and impairment of its structure in the course of diabetes mellitus. Moreover, we observed that HDL-6 subfraction and intermediate HDL fraction are lowest in the group with advanced DMt2 compared to the group with newly diagnosed DM and a healthy control group. Finally, the results of our study indicated the effect of statin treatment on HDL subfractions that seems not to be advantageous. CONCLUSION It seems that in patients with diabetes mellitus compromised antiatherogenic properties of HDL, as a result of oxidative modification and glycation of the HDL protein as well as the transformation of the HDL proteome into a proinflammatory protein, increase cardiovascular risk.

Abstract
Chronic kidney disease is highly prevalent worldwide. The decline of renal function is associated with inadequate removal of a variety of uremic toxins that exert detrimental effects on cells functioning, thus affecting the cardiovascular system. The occurrence of cardiovascular aberrations in CKD is related to the impact of traditional risk factors and non-traditional CKD-associated risk factors, including anemia; inflammation; oxidative stress; the presence of some uremic toxins; and factors related to the type, frequency of dialysis and the composition of dialysis fluid. Cardiovascular diseases are the most frequent cause for the deaths of patients with all stages of renal failure. The kidney is one of the vital sources of antioxidant enzymes, therefore, the impairment of this organ is associated with decreased levels of these enzymes as well as increased levels of pro-oxidants. Uremic toxins have been shown to play a vital role in the onset of oxidative stress. Hemodialysis itself also enhances oxidative stress. Elevated oxidative stress has been demonstrated to be strictly related to kidney and cardiac damage as it aggravates kidney dysfunction and induces cardiac hypertrophy. Antioxidant therapies may prove to be beneficial since they can decrease oxidative stress, reduce uremic cardiovascular toxicity and improve survival.

Abstract
PURPOSE The aim of this study was to assess the levels of selected markers in patients who underwent planned or emergency coronary angiography and to examine if they correlated with the occurrence of AKI. METHODS The study included 52 patients who underwent planned or emergency coronary angiography and received contrast agent. Serum levels of markers (NGAL, L-FABP, KIM-1, IL-18) were analyzed in all patients using ELISA tests, at baseline, after 24 and 72 h from angiography. RESULTS 9.62% of patients developed CI-AKI. No significant differences were observed between markers levels in patients who developed CI-AKI and those who did not. After 24 h, serum levels of IL-18 were higher in patients with CI-AKI, however, this difference was on the verge of significance. Increase in serum NGAL, KIM-1 and IL-18 was observed after 24 h. Serum levels of biomarkers were insignificantly higher in group with CI-AKI. Significant changes in levels in time (baseline vs. 24 h vs. 72 h) were observed only for NGAL [157.9 (92.4-221.0) vs. 201.8 (156.5-299.9) vs. 118.5 (73.4-198.7); p < 0.0001]. No significant correlations were observed between the decrease in eGFR or the increase in creatinine and biomarkers level. CONCLUSION Obtained results do not allow for the indication of efficient AKI biomarkers. Their further validation in large studies of CI-AKI patients is required.

Abstract
An increasing number of evidence indicates that metabolic factors may play an important role in the development and progression of certain types of cancers, including renal cell carcinoma (RCC). This tumour is the most common kidney cancer which accounts for approximately 3–5% of malignant tumours in adults. Numerous studies indicated that concomitant diseases, including diabetes mellitus (DM) and hypertension, as well as obesity, insulin resistance, and lipid disorders, may also influence the prognosis and cancer-specific overall survival. However, the results of studies concerning the impact of metabolic factors on RCC are controversial. It appears that obesity increases the risk of RCC development; however, it may be a favourable factor in terms of prognosis. Obesity is closely related to insulin resistance and the development of diabetes mellitus type 2 (DM2T) since the adipocytes in visceral tissue secrete substances responsible for insulin resistance, e.g., free fatty acids. Interactions between insulin and insulin-like growth factor (IGF) system appear to be of key importance in the development and progression of RCC; however, the exact role of insulin and IGFs in RCC pathophysiology remains elusive. Studies indicated that diabetes increased the risk of RCC, but it might not alter cancer-related survival. The risk associated with a lipid profile is most mysterious, as numerous studies provided conflicting results. Even though large studies unravelling pathomechanisms involved in cancer growth are required to finally establish the impact of metabolic factors on the development, progression, and prognosis of renal cancers, it seems that the monitoring of health conditions, such as diabetes, low body mass index (BMI), and lipid disorders is of high importance in clear-cell RCC.

Abstract
Hypertension is one of the strongest modifiable cardiovascular risk factors, affecting an increasing number of people worldwide. Apart from poor medication adherence, the low efficacy of some therapies could also be related to inter-individual genetic variability. Genetic studies of families revealed that heritability accounts for 30% to 50% of inter-individual variation in blood pressure (BP). Genetic factors not only affect blood pressure (BP) elevation but also contribute to inter-individual variability in response to antihypertensive treatment. This article reviews the recent pharmacogenomics literature concerning the key classes of antihypertensive drugs currently in use (i.e., diuretics, β-blockers, ACE inhibitors, ARB, and CCB). Due to the numerous studies on this topic and the sometimes-contradictory results within them, the presented data are limited to several selected SNPs that alter drug response. Genetic polymorphisms can influence drug responses through genes engaged in the pathogenesis of hypertension that are able to modify the effects of drugs, modifications in drug–gene mechanistic interactions, polymorphisms within drug-metabolizing enzymes, genes related to drug transporters, and genes participating in complex cascades and metabolic reactions. The results of numerous studies confirm that genotype-based antihypertension therapies are the most effective and may help to avoid the occurrence of major adverse events, as well as decrease the costs of treatment. However, the genetic heritability of drug response phenotypes seems to remain hidden in multigenic and multifactorial complex traits. Therefore, further studies are required to analyze all associations and formulate final genome-based treatment recommendations.

Abstract
BACKGROUND There is a close relationship between lipid metabolism disorders and atherosclerosis. Guidelines focus on lowering Low-Density Lipoprotein Cholesterol (LDL-C) levels. However, it should be kept in mind that LDL and High-Density Lipoprotein (HDL) consist of subfractions which can affect the progression of atherosclerosis. OBJECTIVE We assessed the concentration of LDL and HDL subfractions in patients with Acute Coronary Syndromes (ACS). The influence of the presence of type 2 diabetes mellitus on LDL and HDL subfractions was also analyzed. METHODS The study group consisted of 127 patients (62 men, 65 women) with ACS. All patients had coronary angiography and coronary angioplasty and stenting when necessary. Medical history was collected during 12 months of follow-up. HDL and LDL subfraction distribution was measured using Lipoprint (Quantimetrix). RESULTS No differences in LDL nor HDL subfractions were observed between ST-Segment Elevation Myocardial Infarction (STEMI), Non-ST-Segment Elevation Myocardial Infarction (NSTEMI) and unstable angina (UA) patients. However, those with restenosis and the necessity of repeated revascularization had higher levels of intermediate-density lipoprotein C (IDL-C) (p=0.055) and LDL3 (p=0.048) as compared with the patients without, while the level of IDL A (IDLA) was lower than in the latter group (p=0.036). In diabetic patients, the percentage share of HDL10 and small-dense HDL was significantly higher while the share of HDL1 (small-dense) (p=0.028), HDL4 (intermediate density) (p=0.052) and HDL5 (intermediate density) (p=0.060) were lower than in patients without DM. CONCLUSION Patients with multi-vessel CAD disease had higher levels of LDL3 subfraction and IDL-C and a lower proportion of IDLA.

Abstract
Cardiovascular diseases, including hypertension, congestive heart failure, myocardial infarction, stroke and atherosclerosis, are common in patients with chronic kidney disease. Aside from the standard biomarkers, measured to determine cardiovascular risk, new ones have emerged: markers of oxidative stress, apoptosis, inflammation, vascular endothelium dysfunction, atherosclerosis, organ calcification and fibrosis. Unfortunately, their utility for routine clinical application remains to be elucidated. A causal relationship between new markers and cardiovascular diseases in patients with chronic kidney disease remains to be established. First of all, there is a lack of large, randomized trials. Moreover, most studies focus on patients with end-stage renal disease as well as on dialysed patients. In such patients, cardiovascular diseases are already present and advanced while early detection of cardiovascular disease risk factor in patients with early-stages of chronic kidney disease would allow more precise prognosis and, as a result, changes in treatment algorithm. In this article, we conduct a comprehensive review of literature for publications relating to cardiovascular risk factors in patients with early-stages of chronic kidney disease. Overall, there are many encouraging advances in detection of cardiovascular risk factors that are making the future more promising for patients suffering from chronic kidney disease.

Abstract
INTRODUCTION Depressive disorders are the most common mental health problem among patients undergoing dialysis. Furthermore, depression is an independent factor increasing the mortality and frequency of hospitalization in this group of patients, yet psychological intervention programs aimed at improving the mental health of dialysis patients have still not been developed. This meta-analysis aimed to assess the effects of cognitive-behavioral therapy on depressive symptoms in dialysis patients. The main hypothesis of this study is that cognitive-behavioral therapy is an effective psychological method of reducing the severity of depression symptoms among patients undergoing dialysis. MATERIAL AND METHODS A systematic search was conducted using Medline, PubMed, Web of Science, Scopus and Google Scholar. Data extraction was carried out by two independent researchers. The severity of depression symptoms in the included studies was measured by the Beck Depression Inventory. A random-effects model was used to estimate the pooled mean difference of these values between patients undergoing CBT and the controls. RESULTS Four of the 1841 search results met the inclusion criteria with data from 226 patients who had undergone dialysis therapy due to renal disorders and psychological intervention based on cognitive-behavioral therapy. This therapy significantly reduced the level of depression symptoms in all studies included in the meta-analysis (mean difference = -5.3, p = 0.001; 95% CI: -7.95 to -2.66). CONCLUSIONS The study showed that the use of psychological intervention based on cognitive- behavioral therapy was an effective method of decreasing the severity of depressive symptoms in hemodialyzed patients. For the sake of patient well-being, it seems reasonable to extend renal replacement therapy with psychological intervention such as cognitive-behavioral therapy.

Abstract
INTRODUCTION Neuronal nicotinic acetylcholine receptors are ligand-gated ion channel receptors, distributed throughout central nervous system, as well as in peripheral ganglia and some non-neuronal cells. Cytisine, a qulinolizidine alkaloid, could be considered a high affinity ligand of those receptors. It is a partial agonist of β2*-containing receptors and a full agonist of α7 and β4*-containing receptors. Current indication At present, pharmacodynamic properties of cytisine are leveraged only in a few European countries where it is available as medicinal product (Desmoxan and Tabex) indicated in the pharmacotherapy of nicotine addiction. Cytisine mimics the influence of nicotine on α4β2* receptors, but with higher affinity and lower activity. It lowers rewarding and reinforcing effects of nicotine in smoking persons and reduces withdrawal symptoms and craving in quitting ones. Potential indications The results of non-clinical studies suggest that cytisine could affect ethanol consumption, has an antidepressant and neuroprotective effect and could be useful in reducing body mass and preventing weight gain. Although there is a lack of research on cytisine in the treatment of areca nuts usage, the preliminary data suggest its usefulness. The combination of cytisine and Trolox C was selected as a possible effective treatment for type 2 diabetes. Though these drugs alone are not effective, their theoretical usefulness was confirmed in animal models. SUMMARY Treatment with cytisine is an effective, cost-efficient, affordable and well tolerated nicotine addiction therapy. Potential new indications for cytisine include the treatment of alcoholism, areca nuts usage, Parkinson's disease, an autonomic-system failure. Further studies are necessary.

Abstract
Chronic kidney disease (CKD) is a widespread disease with increasing prevalence in the modern society. Lipid disturbances are common in this group of patients. In most patients with CKD atherogenic dyslipidemia is observed. Dyslipidemia in patients with renal diseases increases the risk of cardiovascular diseases and it accelerates the progression of chronic kidney disease to its end stage. The amelioration of dyslipidemia and the lowering of oxidative stress, inflammatory processes, insulin sensitivity and remnant lipoproteins levels may lead to the reduction in cardiovascular burden. Nutritional interventions can strengthen the beneficial effect of treatment and they play an important role in the preservation of overall well-being of the patients with CKD since the aim of appropriate diet is to reduce the risk of cardiovascular events, prevent malnutrition, and hamper the progression of kidney disease. The management of dyslipidemia, regardless of the presence of chronic kidney disease, should be initiated by the introduction of therapeutic lifestyle changes. The introduction of diet change was shown to exert beneficial effect on the lipid level lowering that reaches beyond pharmacological therapy. Currently available evidence give the impression that data on dietary interventions in CKD patients is not sufficient to make any clinical practice guidelines and is of low quality.

Association of statin use and clinical outcomes in heart failure patients: a systematic review and meta-analysis. Lipids Health Dis 2019; 18:188.

Abstract
BACKGROUND The role of statins in patients with heart failure (HF) of different levels of left ventricular ejection fraction (LVEF) remains unclear especially in the light of the absence of prospective data from randomized controlled trials (RCTs) in non-ischemic HF, and taking into account potential statins' prosarcopenic effects. We assessed the association of statin use with clinical outcomes in patients with HF. METHODS We searched PubMed, EMBASE, Scopus, Google Scholar and Cochrane Central until August 2018 for RCTs and prospective cohorts comparing clinical outcomes with statin vs non-statin use in patients with HF at different LVEF levels. We followed the guidelines of the 2009 PRISMA statement for reporting and applied independent extraction by multiple observers. Meta-analyses of hazard ratios (HRs) of effects of statins on clinical outcomes used generic inverse variance method and random model effects. Clinical outcomes were all-cause mortality, cardiovascular (CV) mortality and CV hospitalization. RESULTS Finally we included 17 studies (n = 88,100; 2 RCTs and 15 cohorts) comparing statin vs non-statin users (mean follow-up 36 months). Compared with non-statin use, statin use was associated with lower risk of all-cause mortality (HR 0.77, 95% confidence interval [CI], 0.72-0.83, P < 0.0001, I2 = 63%), CV mortality (HR 0.82, 95% CI: 0.76-0.88, P < 0.0001, I2 = 63%), and CV hospitalization (HR 0.78, 95% CI: 0.69-0.89, P = 0.0003, I2 = 36%). All-cause mortality was reduced on statin therapy in HF with both EF < 40% and ≥ 40% (HR: 0.77, 95% Cl: 0.68-0.86, P < 0.00001, and HR 0.75, 95% CI: 0.69-0.82, P < 0.00001, respectively). Similarly, CV mortality (HR 0.86, 95% CI: 0.79-0.93, P = 0.0003, and HR 0.83, 95% CI: 0.77-0.90, P < 0.00001, respectively), and CV hospitalizations (HR 0.80 95% CI: 0.64-0.99, P = 0.04 and HR 0.76 95% CI: 0.61-0.93, P = 0.009, respectively) were reduced in these EF subgroups. Significant effects on all clinical outcomes were also found in cohort studies' analyses; the effect was also larger and significant for lipophilic than hydrophilic statins. CONCLUSIONS In conclusion, statins may have a beneficial effect on CV outcomes irrespective of HF etiology and LVEF level. Lipophilic statins seem to be much more favorable for patients with heart failure.

Abstract
Abstract
Background
Statin intolerance is a clinical syndrome whereby adverse effects associated with statin therapy (most commonly muscle symptoms) result in the discontinuation of therapy. Statin discontinuation is associated with increased risk of adverse cardiac outcomes. Many patients who initially experience adverse effects are able to tolerate statin therapy to some extent. Careful stepwise diagnosis and management of individuals who experience adverse effects is essential to enable optimal reduction of cardiovascular risk.
Purpose
In this Position Paper of the International Lipid Expert Panel (ILEP), we present a step by step approach to the diagnosis and practical management of statin intolerance resulting from muscle symptoms, and other adverse effects with demonstrated statin causality.
Methods
Relevant clinical evidence and international clinical guidelines were discussed and assimilated by ILEP members. Consensus was used to formulate recommendations for the diagnosis and management of statin intolerance.
Results
Consensus resulted in the adoption of three parts to the recommendation. 1) diagnosis of Statin Intolerance; 2) advice for management of all patients with statin intolerance; 3) specific advice for patients who have partial (rather than complete) statin intolerance. Patients with partial statin intolerance are likely to make up the vast majority (even 95%) of statin-intolerant individuals. Each part of the recommendation consists of a four-step process and has an associated acronym to aid memory (see attached recommendations). We adopted the Banach and Mikhailidis four-step approach to diagnosis and we developed novel recommendations for management.
Summary of the ILEP SI recommendations.
Conclusions
We present recommendations, which will enable clinicians to distinguish between rare, severe adverse effects; true statin intolerance, and symptoms incorrectly attributed to statin therapy. In each case we summarize guidelines, clinical evidence and expert opinion pertaining to the optimal management of cardiovascular disease in these patients.

Abstract
Abstract
Background
Mortality from non-communicable diseases (NCDs) is influenced bymodifiable risk factors. Simple tools which do not require laboratory tests, (blood pressure (BP) [B], exercise [E], weight [W], alimentation [A] (fruit and vegetable consumption), and tobacco [T] (BEWAT) may estimate the risk of all-cause and cause specific mortality.
Purpose
Therefore, we evaluated the link between BEWAT and mortality in a randomly selected sample of the US population.
Method
Adults aged ≥20 years, enrolled in the Third National Health and Nutrition Examination Survey (NHANES-III, 1988–1994) and continuous NHANES (2005–2010), and followed up to December 31st 2011, were included in the present analysis. Multiple Cox regressionswere applied to evaluate the associations between the total BEWAT score and each of its components with all-cause and cause specific mortality.
Results
Overall, 22,968 participants (47.1% men) were included in the present analysis (mean age: 47.4 years). Individuals in the highest BEWAT tertile (T3) had a 25% lower risk of mortality compared with T1 [hazard ratio (HR): 0.75, 95% confidence interval (CI): 0.71–0.79], further corrections slightly diluted the magnitude of link to 22% (HR: 0.78, 95% CI: 0.75–0.81) (Figure). In a fully adjusted model, individuals in T3 also had a 26% lower risk of cardiovascular disease (CVD) mortality compared with those in T1 (HR: 0.74, 95% CI: 0.64–0.83), similar trends were observed across the BEWAT tertiles for cancer mortality risk (participants in T3 had a 31 and 26% lower risk for cancer death in Models 1 and 2, respectively). For sensitivity analyses after excluding smoking from the total BEWAT score, in the fully adjusted model the association between the BEWAT score and cancer death was attenuated but remained significant (HR: 0.80, 95% CI: 0.72–0.89 for T3 vs T1). Furthermore, total BEWAT score (without the BP component) could still predict CVD mortality (T3= HR: 0.71, 95% CI: 0.61–0.82).
All-cause death and BEWAT tertiles.
Conclusion
A higher BEWAT status is beneficial regarding all-cause and cause specific mortality. Our results highlight the value of modifiable risk factors as a simple and affordable variable for evaluating the risk of mortality.

Abstract
Abstract
Background
The reported relationship between coffee intake and renal function is poorly understood.
Purpose
By applying on two-sample Mendelian randomization (MR) and systematic review and meta-analysis we investigated the association between caffeine and coffee intake with prevalent CKD and markers of renal function.
Methods
For the individual data analysis we analysed the NHANES data on renal function markers and caffeine intake. MR was implemented by using summary-level data from genome-wide association studies conducted on coffee intake (N=91,462) and kidney function (N=133,413). Inverse variance weighted method (IVW), weighted median-based method, MR-Egger, MR-RAPS, MR-PRESSO were applied. Random effects models and generic inverse variance methods were used for the meta-analysis.
Results
Finally, we included the data of 18,436 participants, 6.9% had prevalent CKD (based on eGFR). Caffeine intake for general population was 131.1±1.1 mg. The % of pts. with CKD, by caffeine quartile was 16.6% in Q1 (lowest), 13.9% in Q2, 12.2% in Q3 and 11.0% in Q4 (p<0.001). After adjustment, for increasing quartiles for caffeine consumption, mean urine albumin, albumin-creatinine ratio and eGFR did not change significantly (p>0.234). In fully adjusted logistic regression models, there was no significant difference in chances of CKD prevalence (p-trend=0.745) (Table). In the same line, results of MR showed no impact of coffee intake on CKD (IVW=β: −0.0191, SE: 0.069, p=0.781) (Figure), on eGFR (overall= IVW= β: −0.0005, SE: 0.005, p=0.926) both in diabetic (IVW= β: −0.006, SE: 0.009, p=0.478), and non-diabetic patients (IVW= β: −6.772, SE: 0.006, p=0.991). Results from the meta-analysis indicted that coffee consumption was not significantly associated with CKD (OR: 0.85, 95% CI 0.71–1.02, p=0.090, n=6 studies, I2=0.32). These findings were robust in sensitivity analyses.

Abstract
BACKGROUND All stages of chronic kidney disease (CKD) are associated with increased risks of atherosclerosis and cardiovascular morbidity and mortality. According to studies, levels of copeptin, growth differentiation factor-15 (GDF-15) and heart fatty-acid binding protein (h-FABP) are increased in dialysis patients. MATERIALS This study included 50 patients (19 women, 31 men) chronically undergoing haemodialysis. The concentration of markers such as: copeptin, GDF-15, h-FABP, troponin and serum creatine kinase MB (CKMB) was measured with the use of ELISA tests. Serum concentration of 10 high-density lipoprotein (HDL) subfractions and 7 low-density lipoprotein (LDL) subfractions was analysed with the use of Lipoprint™ system (Quantimetrix Corp.). RESULTS In this study, we observed higher copeptin level, lower percentage share of cholesterol HDL4 subfraction and higher percentage share of small HDL particles subfraction in HD patients with diabetes mellitus than in those without diabetes. We also found significantly lower percentage share of cholesterol HDL5 subfraction in patients with GDF-15 > 3rd quartile (Q3) compared with those with GFD-15 ≤ Q3. Finally, it was observed that the percentage share of cholesterol HDL5 subfraction was significantly lower in patients with h-FABP > Q3, and the share of intermediate HDL subfractions was significantly lower in haemodialysis (HD) patients with h-FABP > 75 percentile. CONCLUSION The fact that increased level of one biomarker correlated with higher values of other markers may suggest that their concentration depends on the severity of disease. The obtained results also suggest that the measurement of copeptin may support the diagnosis of cardiovascular problems in dialysis patients.

Abstract
INTRODUCTION Many experimental and clinical trials have suggested that flaxseed might be a potent antihypertensive, but the evidence concerning the effects of flaxseed supplements on plasma C-reactive protein (CRP) concentrations has not been fully conclusive. We assessed the impact of the effects of flaxseed supplementation on plasma CRP concentrations through a systematic review of literature and meta-analysis of available randomised controlled trials (RCTs). MATERIAL AND METHODS The literature search included EMBASE, ProQuest, CINAHL, and PUBMED databases up to 1st February 2016 to identify RCTs investigating the effect of flaxseed supplements on plasma CRP concentrations. Meta-analysis was performed using a random-effects model, and effect size was expressed as weighed mean difference (WMD) and 95% confidence interval (CI). RESULTS Meta-analysis of 17 selected RCTs with 1256 individuals did not suggest a significant change in plasma CRP concentrations following supplementation with flaxseed-containing products (WMD: -0.25 mg/l, 95% CI: -0.53, 0.02, p = 0.074). The effect size was robust in the leave-one-out sensitivity analysis. Subgroup analysis did not suggest any significant difference in terms of changing plasma CRP concentrations among different types of flaxseed supplements used in the included studies, i.e. flaxseed oil (WMD: -0.67 mg/l, 95% CI: -2.00, 0.65, p = 0.320), lignan extract (WMD: -0.32 mg/l, 95% CI: -0.71, 0.06, p = 0.103) and ground powder (WMD: -0.18 mg/l, 95% CI: -0.42, 0.06, p = 0.142). CONCLUSIONS The meta-analysis of RCTs did not show a significant change in plasma CRP concentrations following supplementation with various flaxseed products. Large, well-designed studies should be still performed to validate the current results.

Abstract
Aims Familial hypercholesterolaemia (FH) accelerates atherosclerotic cardiovascular disease (ASCVD) and accordingly is the most potent hereditary cause of premature coronary heart disease. The association between telomere length (TL), a biological index of ageing, and FH has not been hitherto investigated. We addressed this question using data from the US National Health and Education National Surveys (NHANES, 1999-2002). Methods and results We included individuals, who had TL measurements (with quantitative polymerase chain reaction method) and a phenotypic diagnosis of FH based on the Dutch Lipid Clinic Network (DLCN) criteria. Sample weights were applied for unequal probabilities of selection, non-response bias, and oversampling by complex sample analysis. The adult prevalence of FH in NHANES was 0.43% [95% confidence interval (95% CI) 0.33-0.57]. The frequencies of probable FH (mean DLCN score: 6.2) and definite FH (mean DLCN score: 8.9) were 0.42% (95% CI 0.32-0.48) and 0.03% (95% CI 0.02-0.06), respectively. Subjects with FH had a higher prevalence of non-communicable diseases (hypertension, diabetes 2 type, and obesity) and early atherosclerosis (2.9% in overall population vs. 42.2% in FH). Overall, the mean TL in the non-FH population was 1.09 (95% CI 1.06-1.12) (T/S ratio) and 1.09 (95% CI 1.03-1.12) [(T/S ratio) for total FH]. Telomere length adjusted for age, sex, race, and body mass index was shorter in FH compared with healthy subjects (FH 0.89, 95% CI 0.84-0.93 vs. healthy: 1.05, 95% CI 0.97-1.11 T/S ratio; P < 0.001). Subjects with longer TL (highest quartile) had 12% less chance of having FH compared with those with TL in the lowest quartile (Q1, 95% CI 0.78-0.93). Conclusions These preliminary data suggest an association between TL, an index of biological age, and the presence of FH, the most common inherited cause of premature ASCVD. Given our relatively low sample size, the findings need confirmation in larger studies.
