RESUMO
BACKGROUND: COVID-19 is characterized by severe inflammation during the acute phase and increased aortic stiffness in the early postacute phase. In other models, aortic stiffness is improved after the reduction of inflammation. We aimed to evaluate the mid- and long-term effects of COVID-19 on vascular and cardiac autonomic function. The primary outcome was aortic pulse wave velocity (aPWV). METHODS: The cross-sectional Study-1 included 90 individuals with a history of COVID-19 and 180 matched controls. The longitudinal Study-2 included 41 patients with COVID-19 randomly selected from Study-1 who were followed-up for 27 weeks. RESULTS: Study-1: Compared with controls, patients with COVID-19 had higher aPWV and brachial PWV 12 to 24 (but not 25-48) weeks after COVID-19 onset, and they had higher carotid Young's elastic modulus and lower distensibility 12 to 48 weeks after COVID-19 onset. In partial least squares structural equation modeling, the higher the hs-CRP (high-sensitivity C-reactive protein) at hospitalization was, the higher the aPWV 12 to 48 weeks from COVID-19 onset (path coefficient: 0.184; P=0.04). Moreover, aPWV (path coefficient: -0.186; P=0.003) decreased with time. Study-2: mean blood pressure and carotid intima-media thickness were comparable at the end of follow-up, whereas aPWV (-9%; P=0.01), incremental Young's elastic modulus (-17%; P=0.03), baroreflex sensitivity (+28%; P=0.049), heart rate variability triangular index (+15%; P=0.01), and subendocardial viability ratio (+12%; P=0.01×10-4) were significantly improved. There was a trend toward improvement in brachial PWV (-6%; P=0.14) and carotid distensibility (+18%; P=0.05). Finally, at the end of follow-up (48 weeks after the onset of COVID-19) aPWV (+6%; P=0.04) remained significantly higher in patients with COVID-19 than in control subjects. CONCLUSIONS: COVID-19-related arterial stiffening involves several arterial tree portions and is partially resolved in the long-term.

BACKGROUND AND OBJECTIVES: A Mediterranean lifestyle may prevent and mitigate cardiometabolic disorders. We explored whether adherence to a Mediterranean lifestyle was prospectively associated with the risk of metabolic syndrome (MetS) among coronary heart disease (CHD) patients. METHODS: The Coronary Diet Intervention with Olive Oil and Cardiovascular Prevention (CORDIOPREV) study was an interventional diet study to compare a Mediterranean diet with a low-fat diet, in 1002 CHD patients. The Mediterranean lifestyle (MEDLIFE) index was used to assess adherence to a MEDLIFE at baseline, and after 5 years, in 851 participants from the CORDIOPREV study. Subjects were classified as having high (>13 points), moderate (12-13 points), and low (<12 points) adherence to the MEDLIFE. Multivariable logistic regression models were used to determine the association between MEDLIFE adherence and the risk of MetS development or reversal. RESULTS: During the 5-year follow-up, CORDIOPREV participants with high adherence to MEDLIFE had a lower risk of MetS development (odds ratio [OR] 0.37, 95% confidence interval [CI] 0.19-0.75, p < 0.01) and a higher likelihood of reversing preexisting MetS (OR 2.08 CI 95% 1.11-3.91, p = 0.02) compared with participants in the low MEDLIFE adherence group. Each additional one-point increment in the MEDLIFE index was associated with a 24% lower risk of MetS development (OR 0.76, 95% CI 0.64-0.90, p < 0.01) and a 21% higher likelihood of reversing preexisting MetS (OR 1.21 CI 95% 1.04-1.41, p = 0.01). CONCLUSIONS: Our results showed that greater adherence to a MEDLIFE reduced the risk of subsequent MetS development and increased the likelihood of reversing preexisting MetS among patients with CHD at baseline.

Non-Alcoholic Fatty Liver Disease (NAFLD) is a common condition affecting around 10-25% of the general adult population, 15% of children, and even > 50% of individuals who have type 2 diabetes mellitus. It is a major cause of liver-related morbidity, and cardiovascular (CV) mortality is a common cause of death. In addition to being the initial step of irreversible alterations of the liver parenchyma causing cirrhosis, about 1/6 of those who develop NASH are at risk also developing CV disease (CVD). More recently the acronym MAFLD (Metabolic Associated Fatty Liver Disease) has been preferred by many European and US specialists, providing a clearer message on the metabolic etiology of the disease. The suggestions for the management of NAFLD are like those recommended by guidelines for CVD prevention. In this context, the general approach is to prescribe physical activity and dietary changes the effect weight loss. Lifestyle change in the NAFLD patient has been supplemented in some by the use of nutraceuticals, but the evidence based for these remains uncertain. The aim of this Position Paper was to summarize the clinical evidence relating to the effect of nutraceuticals on NAFLD-related parameters. Our reading of the data is that whilst many nutraceuticals have been studied in relation to NAFLD, none have sufficient evidence to recommend their routine use; robust trials are required to appropriately address efficacy and safety.

Dyslipidemia in patients with type 2 diabetes (DMT2) is one of the worst controlled worldwide, with only about 1/4 of patients being on the low-density lipoprotein cholesterol (LDL-C) target. There are many reasons of this, including physicians' inertia, including diabetologists and cardiologists, therapy nonadherence, but also underusage and underdosing of lipid lowering drugs due to unsuitable cardiovascular (CV) risk stratification. In the last several years there is a big debate on the risk stratification of DMT2 patients, with the strong indications that all patients with diabetes should be at least at high cardiovascular disease (CVD) risk. Moreover, we have finally lipid lowering drugs, that not only allow for the effective reduction of LDL-C and do not increase the risk of new onset diabetes (NOD), and/or glucose impairment; in the opposite, some of them might effectively improve glucose control. One of the most interesting is pitavastatin, which is now available in Europe, with the best metabolic profile within statins (no risk of NOD, improvement of fasting blood glucose, HOMA-IR, HbA1c), bempedoic acid (with the potential for the reduction of NOD risk), innovative therapies-PCSK9 inhibitors and inclisiran with no DMT2 risk increase, and new forthcoming therapies, including apabetalone and obicetrapib-for the latter one with the possibility of even decreasing the number of patients diagnosed with prediabetes and DMT2. Altogether, nowadays we have possibility to individualize lipid lowering therapy in DMT2 patients and increase the number of patients on LDL-C goal without any risk of new onset diabetes and/or diabetes control worsening, and in consequence to reduce the risk of CVD complications due to progression of atherosclerosis in this patients' group.

The risk of atherosclerotic cardiovascular disease (ASCVD) is strongly related to lifetime exposure to low-density lipoprotein (LDL)-cholesterol in longitudinal studies. Lipid-lowering therapy (using statins, ezetimibe and PCSK9 inhibitors) substantially ameliorates the risk and is associated with long-term reduction in cardiovascular (CV) events. The robust evidence supporting these therapies supports their continued (and expanding) role in risk reduction. In addition to these 'conventional' therapeutics, while waiting for other innovative therapies, growing evidence supports the use of a range of 'nutraceuticals' (constituents of food prepared as pharmaceutical formulations) including preparations of red yeast rice (RYR), the product of yeast (Monascus purpureus) grown on rice, which is a constituent of food and is used in traditional Chinese medicine. The major active ingredient, monacolin K, is chemically identical to lovastatin. RYR preparations have been demonstrated to be safe and effective in reducing LDL-C, and CV events. However, surprisingly, RYR has received relatively little attention in international guidelines - and conventional drugs with the strongest evidence for event reduction should always be preferred in clinical practice. Nevertheless, the absence of recommendations relating to RYR may preclude the use of a product which may have clinical utility in particular groups of patients (who may anyway self-prescribe this product), what in the consequence might help to reduce population CV risk. This Position Paper of the International Lipid Expert Panel (ILEP) will use the best available evidence to give advice on the use of red-yeast rice in clinical practice.

OBJECTIVE: Contrast-enhanced computed tomography angiography (CTA) is commonly used to investigate acute abdominal conditions, but the risk of contrast-induced acute kidney injury (CI-AKI) has been poorly investigated in patients with acute mesenteric ischemia. The aim of the present study was to evaluate the incidence of CI-AKI in these patients and identify potential predictive factors. METHODS: Patients admitted for acute mesenteric ischemia who had a diagnostic CTA with contrast medium and a follow-up of creatinine concentration were retrospectively included. RESULTS: Among 53 patients included, 9 (16.9%) developed CI-AKI. The prevalence of chronic kidney disease did not differ significantly between those who developed CI-AKI and those who did not (33.3 vs 18.2%, p=.372). Plasma total bilirubin and conjugated bilirubin levels were significantly higher in patients who developed CI-AKI (17.5 vs 8.0 µmol/L, p=.013 and 8.0 vs 3.0 µmol/L, p=.031, respectively). The proportion of patients who had revascularization was similar between patients who developed CI-AKI and those who did not (11.1 vs 20.5%, p>.999). No significant difference was observed for 30-day mortality and all-cause mortality for a median follow-up of 168 days (22.2 vs 13.6%, p=.611; and 33.3 vs 61.4%, p=.153, respectively). CONCLUSION: This study reports the incidence of CI-AKI in patients with acute mesenteric ischemia after diagnostic CTA with contrast medium. Plasma bilirubin levels were a predictive factor of CI-AKI in these patients. The administration of contrast media during revascularization was not associated with an increased risk of CI-AKI.

OBJECTIVES: The recommendations of international guidelines for the management of asymptomatic carotid stenosis (ACS) often vary considerably and extend from a conservative approach with risk factor modification and best medical treatment (BMT) alone, to a more aggressive approach with a carotid intervention plus BMT. The aim of the current multispecialty position statement is to reconcile the conflicting views on the topic. MATERIALS AND METHODS: A literature review was performed with a focus on data from recent studies. RESULTS: Several clinical and imaging high-risk features have been identified that are associated with an increased long-term ipsilateral ischemic stroke risk in patients with ACS. Such high-risk clinical/imaging features include intraplaque hemorrhage, impaired cerebrovascular reserve, carotid plaque echolucency/ulceration/ neovascularization, a lipid-rich necrotic core, a thin or ruptured fibrous cap, silent brain infarction, a contralateral transient ischemic attack/stroke episode, male patients < 75 years and microembolic signals on transcranial Doppler. There is growing evidence that 80-99% ACS indicate a higher stroke risk than 50-79% stenoses. CONCLUSIONS: Although aggressive risk factor control and BMT should be implemented in all ACS patients, several high-risk features that may increase the risk of a future cerebrovascular event are now documented. Consequently, some guidelines recommend a prophylactic carotid intervention in high-risk patients to prevent future cerebrovascular events. Until the results of the much-anticipated randomized controlled trials emerge, the jury is still out regarding the optimal management of ACS patients.

Mitochondria provide energy to the cell during aerobic respiration by supplying ~95% of the adenosine triphosphate (ATP) molecules via oxidative phosphorylation. These organelles have various other functions, all carried out by numerous proteins, with the majority of them being encoded by nuclear DNA (nDNA). Mitochondria occupy ~1/3 of the volume of myocardial cells in adults, and function at levels of high-efficiency to promptly meet the energy requirements of the myocardial contractile units. Mitochondria have their own DNA (mtDNA), which contains 37 genes and is maternally inherited. Over the last several years, a variety of functions of these organelles have been discovered and this has led to a growing interest in their involvement in various diseases, including cardiovascular (CV) diseases. Mitochondrial dysfunction relates to the status where mitochondria cannot meet the demands of a cell for ATP and there is an enhanced formation of reactive-oxygen species. This dysfunction may occur as a result of mtDNA and/or nDNA mutations, but also as a response to aging and various disease and environmental stresses, leading to the development of cardiomyopathies and other CV diseases. Designing mitochondria-targeted therapeutic strategies aiming to maintain or restore mitochondrial function has been a great challenge as a result of variable responses according to the etiology of the disorder. There have been several preclinical data on such therapies, but clinical studies are scarce. A major challenge relates to the techniques needed to eclectically deliver the therapeutic agents to cardiac tissues and to damaged mitochondria for successful clinical outcomes. All these issues and progress made over the last several years are herein reviewed.

Limited data suggests possible gender-specific association between serum uric acid (SUA) and cardiovascular disease (CVD) incidence. The aim of the present analysis was to evaluate the association between SUA levels and 10-year CVD incidence (2002-2012) in the ATTICA study participants. Overall, 1687 apparently healthy volunteers, with SUA measurements, residing in the greater metropolitan Athens area (Greece), were included. Multivariable Cox-regression models were used to estimate the hazard ratios for SUA in relation to 10-year CVD incidence. Receiver operating curve analysis was conducted to detect optimal SUA cut-off values. Participants in the 2nd and 3rd SUA tertile had 29 and 73% higher 10-year CVD incidence compared with those in the 1st tertile (p < 0.001). In gender-specific analysis, only in women SUA was independently associated with CVD incidence; women in the 3rd SUA tertile had 79% greater 10-year CVD event risk compared to their 1st tertile counterparts. Obese in the 3rd SUA tertile had 2-times higher CVD incidence compared to those in the 1st tertile. Similar findings were observed in metabolically healthy (vs. unhealthy) and metabolically healthy obese. SUA thresholds best predicting 10-year CVD incidence was 5.05 and 4.15 mg/dL (0.30 and 0.25 mmol/L) in men and women, respectively. In conclusion, increased SUA levels were independently related to 10-year CVD event rate in women, obese and metabolically healthy individuals. SUA could predict 10-year CVD incidence even at low levels. Further studies are warranted to identify SUA cut-off values that may improve the detection of individuals at higher CVD risk in clinical practice.

PURPOSE OF REVIEW: Hypercholesterolemia is a major risk factor for cardiovascular diseases. Administration of statins represents the cornerstone of the prevention and treatment of cardiovascular disease, with demonstrated long-term safety and efficacy. This review aims to revisit statin intolerance mechanisms, as well as to discuss new data and therapeutic options. RECENT FINDINGS: Although statins are well tolerated, myopathy and other adverse effects are a challenging problem, being the main reason for poor adherence to treatment and failure in lowering cardiovascular risk. Statin intolerance is the subject of ongoing research, as these drugs are widely used. There are alternative options of treatment if statin intolerance emerges, that is, lowering the dose, intermittent dosages, and/or combining a statin with other drugs, such as ezetimibe, proprotein convertase subtilisin-kexin type 9 inhibitors, bempedoic acid, angiopoietin-like 3 protein inhibitors, and nutraceuticals. If even the lowest statin dose cannot be tolerated, a nonstatin regimen is recommended to reduce LDL cholesterol levels. SUMMARY: Treatment options in statin intolerance include combinations of a lower dose of statin with other lipid-lowering regimens or only nonstatin drugs in the presence of complete intolerance. New hypolipidemic therapies that address gene editing are emerging, and may prove useful in the future.

Cardiovascular disease (CVD) remains the first cause of mortality in Western countries. Among cardiometabolic risk factors, dyslipidemia, and especially high low-density lipoprotein cholesterol (LDL-C) concentrations, have been extensively linked to the development and progression of atherosclerosis and to CVD events. Recent evidence has shown that the prevention of unhealthy dietary habits and sedentarism is crucial in the management of dyslipidemia. In this sense, a number of scientific societies recommend the adherence to certain healthy dietary patterns (DPs), such as the Mediterranean diet (MedDiet), the Dietary Approaches to Stop Hypertension (DASH), the Portfolio diet, the Vegetarian diet, the Nordic diet and low-carbohydrate diets, as well as increased physical activity between others. This nutritional and lifestyle advice could be adopted by government bodies and implemented in different health programs as a reliable way of providing health-care professionals with efficient tools to manage cardiometabolic risk factors and thus, prevent CVD. In this narrative review, we will discuss recent data about the effects of nutrition on dyslipidemia, mainly focusing on high LDL-C concentrations and other lipid particles related to atherogenic dyslipidemia such as triglycerides (TG) and non-high density lipoprotein cholesterol (non-HDL-C), that are related to CVD. On the other hand, we also comment on other cardiometabolic risk factors such as type 2 diabetes mellitus (T2DM), high blood pressure (HBP), inflammation and endothelial dysfunction. This review includes food groups as well as different healthy DPs.

BACKGROUND-AIM: Diabetes, obesity and hypertension are common comorbidities associated with increased severity and mortality rates from Corona Virus Disease (COVID)-19. METHODS: In this narrative review (using the PubMed database), we discuss epidemiological data and pathophysiological links between diabetes and COVID-19. The potential effects of glycaemic control and antidiabetic drugs on the prevalence and outcomes of COVID-19 are also reviewed, as well as the role of telemedicine and diabetes self-management in the post-COVID-19 era. RESULTS: Diabetes has been linked to COVID-19 morbidity and mortality, although further research is needed to elucidate this association. In the meantime, physicians should be aware of the potential rise in the prevalence of diabetes (due to unhealthy lifestyle changes during the pandemic), its severity and complications and focus on achieving optimal diabetes prevention and management. Telemedicine and diabetes self-management may help towards this direction. Dipeptidyl-peptidase 4 (DPP4) inhibitors, glucagon-like peptide-1 (GLP-1) receptor agonists and sodium-glucose transporter 2 (SGLT2) inhibitors may affect viral entry and infection, and thus COVID-19 outcomes, as shown in observational studies. CONCLUSION: Diabetes has been associated with COVID-19 development and progression. Certain antidiabetic drugs may influence COVID-19 prevention and management. The results of ongoing randomized clinical trials will shed more light on this field.

PURPOSE OF REVIEW: The present narrative review focuses on the up-to-date clinical data on the correlations between olive oil consumption and cardiovascular (CV) diseases (i.e., CHD, stroke, and peripheral artery disease). RECENT FINDINGS: Olive oil contains monounsaturated fats, several antioxidant phenols, and other micronutrients that mediate CV-protective effects via improvements in oxidative stress, endothelial dysfunction, inflammation, thrombosis, blood pressure, and lipid and carbohydrate metabolism. High consumption of olive oil, and in particular the extra-virgin, which is rich in phenolic antioxidants, has been suggested to prevent against coronary heart disease (CHD). The olive oil-induced cardioprotection was further supported by the findings of a very recent analysis of 2 large US prospective cohort studies showing that a higher olive oil intake was related to a lower risk of CV morbidity and mortality after 24 years of follow-up and that replacement of dairy fat, margarine, butter, or mayonnaise with the equivalent amount of olive oil significantly reduced CV risk. There is evidence for associations between olive oil consumption and lower risk for CV diseases. Both health policy makers and physicians should be aware of these associations and thus promote the intake of olive oil in both primary and secondary prevention settings to minimize individual's CV risk.

CONTEXT: Elevated levels of lipoprotein (a) [Lp(a)] are an independent risk factor for premature cardiovascular disease (CVD). Flaxseed (Linum usitiatissimum L.) is a rich source of alpha-linolenic acid, phytoestrogens, and lignans and has been shown to improve several cardiovascular risk factors, although the overall effect on Lp(a) is unknown. OBJECTIVE: The study intended to assess the impact of flaxseed on plasma Lp(a) levels through a meta-analysis of the results of randomized controlled trials (RCTs). DESIGN: PubMed-Medline, Scopus, Embase, and Google Scholar databases were searched using the following search terms in titles and abstracts: flaxseed OR Linum usitatissimum OR lignin OR linseed AND lipoprotein(a) OR lipoprotein (a) OR Lp(a) OR Lp (a). RESULTS: Of the 48 RCTs, 6 were eligible for inclusion, and the results suggested a significant decrease in plasma Lp(a) levels-standardized mean difference: -0.22, 95% confidence interval: -0.41 to -0.04, P = .017-following supplementation with flaxseed-containing products. CONCLUSIONS: This finding highlights the potential clinical significance of flaxseed supplementation for patients who are at risk of a high residual CVD despite intensive statin therapy, patients with hyperliporoteinemia(a), and patients who prefer natural remedies for CVD prevention in the context of a healthy lifestyle. Further RCTs are needed to establish the role of flaxseed-containing products on lowering Lp(a).

Acute and chronic physical exercises may enhance the development of statin-related myopathy. In this context, the recent (2019) guidelines of the European Society of Cardiology (ESC) and the European Atherosclerosis Society (EAS) for the management of dyslipidemias recommend that, although individuals with dyslipidemia should be advised to engage in regular moderate physical exercise (for at least 30â¯min daily), physicians should be alerted with regard to myopathy and creatine kinase (CK) elevation in statin-treated sport athletes. However it is worth emphasizing that abovementioned guidelines, previous and recent ESC/EAS consensus papers on adverse effects of statin therapy as well as other previous attempts on this issue, including the ones from the International Lipid Expert Panel (ILEP), give only general recommendations on how to manage patients requiring statin therapy on regular exercises. Therefore, these guidelines in the form of the Position Paper are the first such an attempt to summary existing, often scarce knowledge, and to present this important issue in the form of step-by-step practical recommendations. It is critically important as we might observe more and more individuals on regular exercises/athletes requiring statin therapy due to their cardiovascular risk.

Background: Insulin response to diet might predict the risk of mortality; however, the evidence is limited. We prospectively evaluated the link between the dietary hyperinsulinemia index (DHI) and dietary insulin resistance index (DIRI) with all-cause and cause-specific (cardiovascular disease [CVD] and cancer) mortality.Methods: The National Health and Nutrition Examination Survey (1999-2010) database was used. Vital status through December 31, 2011, was ascertained. Stepwise linear regression models consisted of 39 macro/micronutrients applied, and fasting plasma C-peptide for the DHI and triglyceride/high-density lipoprotein cholesterol ratio (TG/HDL-C) for the DIRI were used. Adjusted Cox regression (followed by propensity score matching) was performed to determine the hazard ratios (HRs) and 95% confidence interval (95% CIs).Results: Overall, 22,246 participants were included (mean age = 47.8 years; 48.9% men). There was a significant increasing risk of mortality across the quartiles of DHI, i.e., participants with a highest score of DHI (Q4) had a greater risk of all-cause (HR: 1.21, 95% CI: 1.17-1.26), CVD (HR: 1.17, 95% CI: 1.07-1.29), and cancer (HR: 1.15, 95% CI: 1.08-1.23) mortality compared with the first quartile (Q1; p < 0.001 for all comparisons). Similarly, participants in the highest DIRI quartile (Q4) had 23% and 31% higher risk of all-cause and CVD mortality, respectively, compared with Q1, while the association between cancer mortality and DIRI was non-significant (HR: 0.88, 95% CI: 0.35-2.61).Conclusions: These findings highlight, for the first time, the detrimental role (association) of insulinemia and insulin resistance potential of diet on all-cause and cause-specific mortality. Our findings support the role of C-peptide and TG/HDL-C ratio as cost-effective and practical biomarkers in clinical settings. These results need to be confirmed to establish their implications.

The present meta-analysis evaluated the efficacy and safety of empagliflozin + linagliptin combination compared with either monotherapy [n=6 randomized controlled trials; 2857 adults with type 2 diabetes (T2DM) on diet + exercise ± metformin; 39.7% women; mean age: 54.6-59.9 years]. The combination of empagliflozin 10 mg + linagliptin 5 mg led to significantly greater reductions in glycated haemoglobin (HbA1c) compared with either drug alone over 24 weeks: weighted mean difference [WMD; -0.72%, 95% confidence interval (CI): -1.04, -0.40], and fasting plasma glucose (-1.60 mmol/L 95% CI: -2.21, -1.00). Similar results were observed when empagliflozin 25 mg + linagliptin 5 mg was compared with linagliptin 5 mg monotherapy or with empagliflozin 10 or 25 mg monotherapy. Patients with T2DM treated with the drug combination had more than three times higher likelihood of achieving HbA1c <7% than those on either monotherapy. Weight reduction was significantly greater in the combination group only when compared with linagliptin monotherapy. Safety profile was similar between combination treatment and monotherapies. Overall, the empagliflozin + linagliptin combination had superior efficacy and similar safety in achieving euglycaemia compared with either monotherapy. This combination, administered once daily, has the potential to reduce regimen complexity, enhance adherence and improve outcomes in clinical practice.

BACKGROUND: Although primary hyperparathyroidism has been associated with insulin resistance, potential optimal effects of parathyroidectomy (PTX) on glucose homeostasis remain controversial. Accordingly, the impact of PTX on glucose-stimulated incretin (glucagon-like peptide 1 [GLP-1] and gastric inhibitory peptide) secretion has not been evaluated. The aim of this pilot study was to compare glucose-stimulated incretin secretion (GSIS) in patients with asymptomatic primary hyperparathyroidism with normal glucose homeostasis, before and after PTX. METHODS: Fourteen patients were included in the study. Fasting calcium, parathyroid hormone, glucose, insulin, GLP-1, and gastric inhibitory peptide were measured pre- and post-operatively. Homeostasis Model Assessment 2, QUICKI, and Matsuda indexes were used as markers of insulin sensitivity and resistance before and after PTX. Preoperatively, a 75 g oral glucose tolerance test (OGTT) was performed to evaluate the response of glucose, insulin, and GSIS. OGTT measurements were repeated 6 ± 2 wk post-PTX. RESULTS: Patients had a mean age of 52.93 ± 9.96 y, and female-to-male ratio was 12:2. Pre- and post-operatively, a positive correlation between parathyroid hormone and Homeostasis Model Assessment 2 for ß-cell function was evident (r = 0.74, P = 0.002 and r = 0.55, P = 0.04, respectively). After PTX, a significant increase in GSIS for GLP-1 during OGTT was observed (in 60 min: 63.06 ± 44.78 versus 102.64 ± 40.19 pg/mL, P = 0.02; and in 120 min: 71.20 ± 35.90 versus 102.49 ± 40.02 pg/mL, P = 0.03). CONCLUSIONS: The increase of GLP-1 response following oral glucose load after PTX may reflect an initial recovery phase of glucose homeostasis. Long-term studies are required to elucidate the physiological interplay between the normalization of calciotropic axis and the rising GLP-1 concentrations post-PTX.

No data exist on the associations of dietary tomato and lycopene consumption with total and cause-specific mortality. Using the National Health and Nutrition Examination Surveys 1999-2010, we evaluted the long-term impact of tomato and lycopene intake on total and cause-specific (CHD and cerebrovascular disease) mortality. We also assessed the changes in cardio-metabolic risk factors according to tomato and lycopene intake. Vital status to 31 December 2011 was ascertained. Cox proportional hazard regression models (followed by propensity score matching) were used to investigate the link between tomato and lycopene consumption total, CHD and cerebrovascular mortality. Among the 23 935 participants included (mean age = 47·6 years, 48·8 % men), 3403 deaths occurred during 76·4 months of follow-up. Tomato intake was inversely associated with total (risk ratio (RR) 0·86, 95 % CI 0·81, 0·92), CHD (RR 0·76, 95 % CI 0·70, 0·85) and cerebrovascular (RR 0·70, 95 % CI 0·62, 0·81) mortality. Similar inverse associations were found between lycopene consumption, total (RR 0·76, 95 % CI 0·72, 0·81), CHD (RR 0·73, 95 % CI 0·65, 0·83) and cerebrovascular (RR 0·71, 95 % CI 0·65, 0·78) mortality; these associations were independent of anthropometric, clinical and nutritional parameters. Age and obesity did not affect the association of tomato and lycopene consumption with total, CHD and cerebrovascular mortality. C-reactive protein significantly moderated the link between lycopene and tomato intake with total, CHD and cerebrovascular mortality. ANCOVA showed that participants with a higher tomato and lycopene consumption had a more cardio-protective profile compared with those with a lower intake. Our results highlighted the favourable effect of tomato and lycopene intake on total and cause-specific mortality as well as on cardio-metabolic risk factors. These findings should be taken into consideration for public health strategies.

BACKGROUND: Familial hypercholesterolemia (FH) is characterized by elevated low-density lipoprotein cholesterol (LDL-C) levels and increased cardiovascular disease (CVD) risk. FH patients often have increased lipoprotein(a) [Lp(a)] levels, which further increase CVD risk. Novel methods for accurately calculating LDL-C have been proposed. METHODS: Patients with FH were recruited by a network of Greek sites participating in the HELLAS-FH registry. LDL-C levels were calculated using the Friedewald (LDL-CF) and the Martin/Hopkins (LDL-CM/H) equations as well as after correcting LDL-CM/H for Lp(a) levels [LDL-CLp(a)corM/H]. The objective was to compare LDL-C levels and target achievement as estimated by different methods in FH patients. RESULTS: This analysis included 1620 patients (1423 adults and 197 children). In adults at diagnosis, LDL-CF and LDL-CM/H levels were similar [235 ± 70 mg/dL (6.1 ± 1.8 mmol/L) vs 235 ± 69 mg/dL (6.1 ± 1.8 mmol/L), respectively; P = NS], while LDL-CLp(a)corM/H levels were non-significantly lower than LDL-CF [211 ± 61 mg/dL (5.5 ± 1.6 mmol/L); P = 0.432]. In treated adults (n = 966) both LDL-CF [150 ± 71 mg/dL (3.9 ± 1.8 mmol/L)] and LDL-CM/H levels [151 ± 70 mg/dL (6.1 ± 1.8 mmol/L); P = 0.746] were similar, whereas LDL-CLp(a)corM/H levels were significantly lower than LDL-CF [121 ± 62 mg/dL (3.1 ± 1.6 mmol/L); P < 0.001]. Target achievement as per latest guidelines in treated patients using the LDL-CM/H (2.5%) and especially LDL-CLp(a)corM/H methods (10.7%) were significantly different than LDL-CF (2.9%; P < 0.001). In children, all 3 formulas resulted in similar LDL-C levels, both at diagnosis and in treated patients. However, target achievement by LDL-CF was lower compared with LDL-CM/H and LDL-CLp(a)corM/H methods (22.1 vs 24.8 vs 33.3%; P < 0.001 for both comparisons). CONCLUSION: LDL-CLp(a)corM/H results in significantly lower values and higher target achievement rate in both treated adults and children. If validated in clinical trials, LDL-CLp(a)corM/H may become the method of choice to more accurately estimate 'true' LDL-C levels in FH patients.
