Abstract
BACKGROUND Lipids have immunomodulatory functions and the potential to affect cancer immunity. METHODS The associations of pretreatment serum cholesterol and long-chain fatty acids with the objective response rate (ORR), progression-free survival (PFS), and overall survival (OS) were evaluated in 148 patients with non-small cell lung cancer who received nivolumab. RESULTS When each lipid was separately evaluated, increased low-density lipoprotein (LDL)-cholesterol (P < 0.001), high-density lipoprotein (HDL)-cholesterol (P = 0.014), total cholesterol (P = 0.007), lauric acid (P = 0.015), myristic acid (P = 0.022), myristoleic acid (P = 0.035), stearic acid (P = 0.028), linoleic acid (P = 0.005), arachidic acid (P = 0.027), eicosadienoic acid (P = 0.017), dihomo-γ-linolenic acid (P = 0.036), and behenic acid levels (P = 0.032) were associated with longer PFS independent of programmed death ligand 1 (PD-L1) expression. Meanwhile, increased LDL-cholesterol (P < 0.001), HDL-cholesterol (P = 0.009), total cholesterol (P = 0.036), linoleic acid (P = 0.014), and lignoceric acid levels (P = 0.028) were associated with longer OS independent of PD-L1 expression. When multiple lipids were evaluated simultaneously, LDL-cholesterol (P = 0.003), HDL-cholesterol (P = 0.036), and lauric acid (P = 0.036) were independently predictive of PFS, and LDL-cholesterol (P = 0.008) and HDL-cholesterol (P = 0.031) were predictive of OS. ORR was not associated with any serum lipid. CONCLUSIONS Based on the association of prolonged survival in patients with increased serum cholesterol and long-chain fatty acid levels, serum lipid levels may be useful for predicting the efficacy of immune checkpoint inhibitor therapy.

Abstract
Postmenopausal women are at higher risk of developing cardiovascular diseases due to changes in lipid profile and body fat, among others. The aim of this study was to evaluate the association of urinary tartaric acid, a biomarker of wine consumption, with anthropometric (weight, waist circumference, body mass index (BMI), and waist-to-height ratio), blood pressure, and biochemical variables (blood glucose and lipid profile) that may be affected during the menopausal transition. This sub-study of the PREDIMED (Prevención con Dieta Mediterránea) trial included a sample of 230 women aged 60-80 years with high cardiovascular risk at baseline. Urine samples were diluted and filtered, and tartaric acid was analyzed by liquid chromatography coupled to electrospray ionization tandem mass spectrometry (LC-ESI-MS/MS). Correlations between tartaric acid and the study variables were adjusted for age, education level, smoking status, physical activity, BMI, cholesterol-lowering, antihypertensive, and insulin treatment, total energy intake, and consumption of fruits, vegetables, and raisins. A strong association was observed between wine consumption and urinary tartaric acid (0.01 μg/mg (95% confidence interval (CI): 0.01, 0.01), p-value < 0.001). Total and low-density lipoprotein (LDL) cholesterol were inversely correlated with urinary tartaric acid (-3.13 μg/mg (-5.54, -0.71), p-value = 0.016 and -3.03 μg/mg (-5.62, -0.42), p-value = 0.027, respectively), whereas other biochemical and anthropometric variables were unrelated. The results suggest that wine consumption may have a positive effect on cardiovascular health in postmenopausal women, underpinning its nutraceutical properties.

Abstract
BACKGROUND Peripheral artery disease (PAD) is recognized as a significant predictor of mortality and adverse cardiovascular outcomes in patients with coronary heart disease (CHD). In fact, coexisting PAD and CHD is strongly associated with a greater coronary event recurrence compared with either one of them alone. High-density lipoprotein (HDL)-mediated cholesterol efflux capacity (CEC) is found to be inversely associated with an increased risk of incident CHD. However, this association is not established in patients with PAD in the context of secondary prevention. In this sense, our main aim was to evaluate the association between CEC and PAD in patients with CHD and whether the concurrent presence of PAD and T2DM influences this association. METHODS CHD patients (n = 1002) from the CORDIOPREV study were classified according to the presence or absence of PAD (ankle-brachial index, ABI ≤ 0.9 and ABI > 0.9 and < 1.4, respectively) and T2DM status. CEC was quantified by incubation of cholesterol-loaded THP-1 cells with the participants' apoB-depleted plasma was performed. RESULTS The presence of PAD determined low CEC in non-T2DM and newly-diagnosed T2DM patients. Coexisting PAD and newly-diagnosed T2DM provided and additive effect providing an impaired CEC compared to non-T2DM patients with PAD. In established T2DM patients, the presence of PAD did not determine differences in CEC, compared to those without PAD, which may be restored by glucose-lowering treatment. CONCLUSIONS Our findings suggest an inverse relationship between CEC and PAD in CHD patients. These results support the importance of identifying underlying mechanisms of PAD, in the context of secondary prevention, that provide potential therapeutic targets, that is the case of CEC, and establishing strategies to prevent or reduce the high risk of cardiovascular events of these patients.

Abstract
BACKGROUND AND AIMS High serum netrin-1 levels decrease the risk of ischemic stroke and are negatively associated with outcomes after ischemic stroke. However, it remains unclear whether the association between netrin-1 and ischemic stroke prognosis is modified by lipid component levels. METHODS AND RESULTS We measured baseline serum netrin-1 levels in 3065 ischemic stroke patients from China Antihypertensive Trial in Acute Ischemic Stroke (CATIS). The primary outcome was a combination of death and major disability (modified Rankin Scale score≥3) at 3 months after ischemic stroke. Total cholesterol (TC) levels could modify the association between netrin-1 and prognosis of ischemic stroke (Pinteraction = 0.040). After multivariate adjustment, the odds ratios of the primary outcome associated with the highest quartile of netrin-1 were 0.39 (95%CI, 0.17-0.90; Ptrend = 0.004) for the patients with high TC levels and 0.82 (95%CI, 0.61-1.11; Ptrend = 0.149) for those with normal TC levels. Adding netrin-1 to conventional risk factors improved risk prediction for the primary outcome in the patients with high TC levels (net reclassification improvement: 26.8%, P = 0.015; integrated discrimination index: 1.6%, P = 0.028) but not in those with normal TC levels. CONCLUSIONS Elevated netrin-1 is associated with improved prognosis at 3 months after ischemic stroke in the patients with high TC levels but not in those with normal TC levels. Further prospective studies from other populations and randomized clinical trials are needed to verify our findings and clarify the potential mechanisms.

Abstract
The prevalence of atherosclerotic diseases is higher in hemodialysis patients. The aim of the current study was to investigate associations between cholesterol level and the incidences of cardiovascular disease (CVD) and mortality in hemodialysis patients. A total of 3517 participants undergoing maintenance hemodialysis were followed up for 10 years. Total cholesterol (TC) level was divided into quartile in baseline data. The multivariate analyses were calculated by a Cox proportional hazards model. The incidences of ischemic heart disease (IHD), peripheral artery disease (PAD), and CVD were significantly positively associated with higher cholesterol levels after adjustment for confounding factors (P < 0.01, P = 0.04, and P < 0.01, respectively). Furthermore, the incidences of cancer-associated mortality and all-cause mortality were significantly positively associated with lower cholesterol levels after adjustment for confounding factors (both P < 0.01). The lowest TC level at all-cause mortality risk was 179 mg/dL. From these results, higher TC predicts IHD, PAD, and CVD events, and lower TC predicts cancer-associated mortality and all-cause mortality in patients undergoing maintenance hemodialysis.

Abstract
BACKGROUND To examine the association between the degree of risk factor control and cardiovascular disease (CVD) risk in type 2 diabetes and to assess if the presence of cardio-renal disease modifies these relationships. METHODS A retrospective cohort study using data from English practices from CPRD GOLD (Clinical Practice Research Datalink) and the SCI-Diabetes dataset (Scottish Care Information-Diabetes), with linkage to hospital and mortality data. We identified 101 749 with type 2 diabetes (T2D) in CPRD matched with 378 938 controls without diabetes and 330 892 with type 2 diabetes in SCI-Diabetes between 2006 and 2015. The main exposure was number of optimized risk factors: nonsmoker, total cholesterol ≤4 mmol/L, triglycerides ≤1.7 mmol/L, glycated haemoglobin (HbA1c) ≤53 mmol/mol (≤7.0%), systolic blood pressure <140mm Hg, or <130 mm Hg if high risk. Cox models were used to assess cardiovascular risk associated with levels of risk factor control. RESULTS In CPRD, the mean baseline age in T2D was 63 years and 28% had cardio-renal disease (SCI-Diabetes: 62 years; 35% cardio-renal disease). Over 3 years follow-up (SCI-Diabetes: 6 years), CVD events occurred among 27 900 (27%) CPRD-T2D, 101 362 (31%) SCI-Diabetes-T2D, and 75 520 (19%) CPRD-controls. In CPRD, compared with controls, T2D participants with optimal risk factor control (all risk factors controlled) had a higher risk of CVD events (adjusted hazard ratio, 1.21; 95% confidence interval, 1.12-1.29). In T2D participants from CPRD and SCI-Diabetes, pooled hazard ratios for CVD associated with 5 risk factors being elevated versus optimal risk factor control were 1.09 (95% confidence interval, 1.01-1.17) in people with cardio-renal disease but 1.96 (95% confidence interval, 1.82-2.12) in people without cardio-renal disease. People without cardio-renal disease were younger and more likely to have likely to have suboptimal risk factor control but had fewer prescriptions for risk factor modifying medications than those with cardio-renal disease. CONCLUSIONS Optimally managed people with T2D have a 21% higher CVD risk when compared with controls. People with T2D without cardio-renal disease would be predicted to benefit greatly from CVD risk factor intervention.

Abstract
BACKGROUND Genetic, observational, and clinical intervention studies indicate that circulating levels of triglycerides and cholesterol transported in triglyceride-rich lipoproteins (remnant cholesterol) can predict cardiovascular events. OBJECTIVES This study evaluated the association of triglycerides and remnant cholesterol (remnant-C) with major cardiovascular events in a cohort of older individuals at high cardiovascular risk. METHODS This study determined the baseline lipid profile and searched for major adverse cardiovascular events (MACEs) in the high-risk primary prevention PREDIMED (Prevención con Dieta Mediterránea) trial population (mean age: 67 years; body mass index: 30 kg/m2; 43% men; 48% with diabetes) after a median follow-up of 4.8 years. Unadjusted and adjusted Cox proportional hazard models were used to assess the association between lipid concentrations (either as continuous or categorical variables) and incident MACEs (N = 6,901; n cases = 263). RESULTS In multivariable-adjusted analyses, triglycerides (hazard ratio [HR]: 1.04; 95% confidence interval [CI]: 1.02 to 1.06, per 10 mg/dl [0.11 mmol/l]; p < 0.001), non-high-density lipoprotein cholesterol (HDL-C) (HR: 1.05; 95% CI: 1.01 to 1.10, per 10 mg/dl [0.26 mmol/l]; p = 0.026), and remnant-C (HR: 1.21; 95% CI: 1.10 to 1.33, per 10 mg/dl [0.26 mmol/l]; p < 0.001), but not low-density lipoprotein cholesterol (LDL-C) or HDL-C, were associated with MACEs. Atherogenic dyslipidemia (triglycerides >150 mg/dl [1.69 mmol/l] and HDL-C <40 mg/dl [1.03 mmol/l] in men or <50 mg/dl [1.29 mmol/l] in women) was also associated with MACEs (HR: 1.44; 95% CI: 1.04 to 2.00; p = 0.030). Remnant-C ≥30 mg/dl (0.78 mmol/l) differentiated subjects at a higher risk of MACEs compared with those at lower concentrations, regardless of whether LDL-C levels were on target at ≤100 mg/dl (2.59 mmol/l). CONCLUSIONS In overweight or obese subjects at high cardiovascular risk, levels of triglycerides and remnant-C, but not LDL-C, were associated with cardiovascular outcomes independent of other risk factors.

Abstract
BACKGROUND Comprehensive control of multiple cardiovascular risk factors reduces cardiovascular risk but is difficult to achieve. DESIGN A multinational, cross-sectional, observational study. METHODS The International ChoLesterol management Practice Study (ICLPS) investigated achievement of European Society of Cardiology (ESC)/European Atherosclerosis Society (EAS) guideline low-density lipoprotein cholesterol (LDL-C) targets in patients receiving lipid-modifying therapy in countries outside Western Europe. We examined the rate of, and association between, control of multiple risk factors in ICLPS participants with dyslipidaemia, diabetes and hypertension (N = 2377). RESULTS Mean (standard deviation) age of patients was 61.4 (10.4) years; 51.3% were male. Type 2 diabetes was the most common form of diabetes (prevalence, 96.9%). The prevalence of metabolic syndrome was 67.8%, obesity 40.4%, atherosclerotic disease 39.6% and coronary artery disease 33.5%. All patients were at high (38.2%) or very high (61.8%) cardiovascular risk according to ESC/EAS guidelines. Body mass index (BMI) was <25 kg/m2 in 20.3% of patients, 62.8% had never smoked and 25.2% were former smokers. Overall, 12.2% achieved simultaneous control of LDL-C, diabetes and blood pressure. Risk factor control was similar across all participating countries. The proportion of patients achieving individual guideline-specified treatment targets was 43.9% for LDL-C, 55.5% for blood pressure and 39.3% for diabetes. Multiple correspondence analysis indicated that control of LDL-C, control of blood pressure, control of diabetes, BMI and smoking were associated. CONCLUSION Comprehensive control of multiple cardiovascular risk factors in high-risk patients is suboptimal worldwide. Failure to control one risk factor is associated with poor control of other risk factors.

Menotti, A, Puddu, PE, Kromhout, D, Kafatos, A, Tolonen, H
European journal of preventive cardiology. 2020;(9):988-998
Abstract
OBJECTIVES The purpose of this study was to relate risk factor changes during decades with 50-year coronary heart disease mortality in European cohorts of middle-aged men of the Seven Countries Study. MATERIAL AND METHODS In the 1950s-early 1960s, nine cohorts of 6518 men aged 40-59 years were examined in five European countries. Smoking habits, systolic blood pressure and serum cholesterol were measured at entry and five times during the next 35 years and a comprehensive Risk Factor Change Score was created. Coronary heart disease mortality data was collected during a 50-year follow-up, modelled by the Weibull distribution, whose shape (Weibull shape) was related to the Risk Factor Change Score by linear regression. RESULTS The Risk Factor Change Score showed slight declines in the Finnish and Dutch cohorts, moderate or large increases in the other cohorts. These effects were related to a decrease of smoking habits in all cohorts, an increase of blood pressure in all cohorts except East Finland, a decrease of serum cholesterol in Finland and the Netherlands, whereas serum cholesterol increases were slight in Italy and large in Serbia and Greece. Weibull distribution shape for coronary heart disease mortality showed slight deceleration in one Finnish and the Dutch cohorts, large acceleration in the Serbian and Greek cohorts. The correlation coefficient of the Risk Factor Change Score versus Weibull shape for the nine cohorts was 0.78 (R2 = 0.60; p = 0.0132). CONCLUSIONS Spontaneous long-term changes of major coronary risk factor levels were associated with changes in the same direction of coronary heart disease mortality risk modelled by the Weibull distribution, expressing a kind of 'natural experiment' with an outcome that matches those of controlled preventive trials.

American heart journal. 2019;:54-62
Abstract
BACKGROUND In the FOURIER trial, evolocumab, a proprotein convertase subtilisin-kexin type 9 inhibitor, reduced cardiovascular events in patients with atherosclerotic cardiovascular disease (ASCVD). We aimed to examine how closely patients in routine practice resemble the FOURIER trial participants and to assess the observed cardiovascular risks based on trial eligibility and underrepresentativeness. METHODS Using a large US administrative database with linked laboratory data, we identified adult patients with ASCVD between January 1, 2012, and December 31, 2016. We identified the excluded and underrepresented populations and examined the risk of cardiovascular events (a composite endpoint of myocardial infarction [MI], stroke, angina, and coronary revascularization) based on trial eligibility and underrepresentativeness. RESULTS Only 15.2% of 233,977 patients met the FOURIER eligibility. Nearly 60% of the ineligible patients met at least 2 exclusion criteria. Among trial-eligible patients, elderly patients, women, minorities, and those without prior MI were underrepresented in FOURIER. Patients who would have been excluded from FOURIER had a diverse risk profile but, on average, had a lower cardiovascular risk than those who would have qualified (hazard ratio [HR] 0.84 [0.81-0.88], P < .001). Among the underrepresented patients, women and patients without prior MI had a lower cardiovascular risk (HR 0.77 [0.71-0.82], P < .001; HR 0.67 [0.63-0.72], P < .001, respectively). Only 47.2% of patients were on moderate-/high-intensity statins. CONCLUSIONS One in 7 ASCVD patients in practice would have qualified for FOURIER. The excluded and underrepresented populations were at a particularly low or high cardiovascular risk. Statin therapy was underused, and physicians may need to evaluate adherence before adding a proprotein convertase subtilisin-kexin type 9 inhibitor.
