Background and aims: Human and planetary health are inextricably interconnected through food systems. Food choices account for 50% of all deaths for cardiovascular diseases (CVD) - the leading cause of death in Europe - and food systems generate up to 37% of total greenhouse gas (GHG) emissions. Methods and results: Based on a systematic revision of meta-analyses of prospective studies exploring the association between individual foods/food groups and the incidence of CVD, we identified a dietary pattern able to optimize CVD prevention.. This dietary pattern was compared to the current diet of the European population. The nutritional adequacy of both diets was evaluated according to the European Food Safety Authority (EFSA) recommended nutrient intake for the adult population, and their environmental impact was evaluated in terms of carbon footprint (CF). As compared to the current diet, the desirable diet includes higher intakes of fruit, vegetables, wholegrains, low glycemic index (GI) cereals, nuts, legumes and fish, and lower amounts of beef, butter, high GI cereals or potatoes and sugar. The diet here identified provides appropriate intakes of all nutrients and matches better than the current Europeans' one the EFSA requirements. Furthermore, the CF of the proposed diet is 48.6% lower than that of the current Europeans' diet. Conclusion: The transition toward a dietary pattern designed to optimize CVD prevention would improve the nutritional profile of the habitual diet in Europe and, at the same time, contribute to mitigate climate change by reducing the GHG emissions linked to food consumption almost by half.

Background: Our aims were to evaluate the relationship of habitual legume consumption with blood pressure (BP) control in a large cohort of people with T2D and hypertension, and to investigate whether specific nutritional components of legumes or other foods may contribute to regulate BP levels. Methods: We studied 1897 participants with T2D and hypertension. Dietary habits were assessed through a validated food frequency questionnaire. Sex-specific quartiles of legume consumption were created. Results: Higher legume consumption was associated with a lower intake of energy, carbohydrates, glycaemic load, alcohol, and sodium, and a significantly greater intake of proteins, fat, monounsaturated, polyunsaturated, fibre, potassium, and polyphenols. Significantly lower systolic and diastolic BP values were observed in the highest vs. lowest quartile of legume consumption (132.9 ± 6.7 vs. 137.3 ± 7.0 mmHg, p < 0.001; 78.9 ± 4.1 vs. 81.0 ± 4.2 mmHg, p = 0.002; respectively), as well as the proportion of people meeting the treatment targets (61.3% vs. 37.4% and 71.3% vs. 52.4%, respectively, p < 0.01). This association was independent from other foods whose consumption is associated with the high legume intake. Conclusions: In people with T2D and hypertension, three servings of legumes per week are associated with significantly better BP control. This gives further support to current dietary guidelines in recommending the frequent consumption of legumes, as a “ready-to-use” dietary strategy to achieve optimal BP control.

Background and aims To investigate diabetes treatment initiation and continuation in the next sixth months in newly diagnosed Italian subjects. Methods and results We analyzed administrative claims of 11,300,750 Italian residents. Subjects with incident diabetes were identified by glucose lowering drug prescriptions, disease-specific co-payment exemptions and hospital discharge codes occurring in 2018 but not in 2017. Incident cases were 65,932 of whom 91.4% received the prescription of a glucose lowering drug. Among the latter, those receiving a prescription of a noninsulin medication but no insulin were 84.8%, those receiving a prescription of insulin only were 9.4%, and those receiving prescriptions of both insulin and noninsulin drugs were 5.8%. Metformin was the most frequently drug initially prescribed in noninsulin treated subjects (~85%) and sulphonylurea receptor (SUR) agonists collectively ranked as second (~13%). Lispro (35%) and glargine (34%) were the most frequently prescribed molecules in subjects who were insulin treated. Differences in prescriptions were found in age categories, with increased use of SUR agonists across decades. In the first six months, as many as 50% of noninsulin treated patients continued with the initial drug, ~15% added a second agent, ~5% switched to another medication, and ~30% discontinued any glucose lowering treatment. Conclusions These data document that current guidelines are often neglected because prescriptions of SUR agonists as first agent are still quite common and insulin is prescribed more than expected. They point out the urgent need to improve the dissemination and implementations of guidelines in diabetes care.

This review aims at summarizing updated evidence on cardiovascular disease (CVD) risk associated with consumption of specific food items to substantiate dietary strategies for atherosclerosis prevention. A systematic search on PubMed was performed to identify meta-analyses of cohort studies and RCTs with CVD outcomes. The evidence is highly concordant in showing that, for the healthy adult population, low consumption of salt and foods of animal origin, and increased intake of plant-based foods—whole grains, fruits, vegetables, legumes, and nuts—are linked with reduced atherosclerosis risk. The same applies for the replacement of butter and other animal/tropical fats with olive oil and other unsaturated-fat-rich oil. Although the literature reviewed overall endorses scientific society dietary recommendations, some relevant novelties emerge. With regard to meat, new evidence differentiates processed and red meat—both associated with increased CVD risk—from poultry, showing a neutral relationship with CVD for moderate intakes. Moreover, the preferential use of low-fat dairies in the healthy population is not supported by recent data, since both full-fat and low-fat dairies, in moderate amounts and in the context of a balanced diet, are not associated with increased CVD risk; furthermore, small quantities of cheese and regular yogurt consumption are even linked with a protective effect. Among other animal protein sources, moderate fish consumption is also supported by the latest evidence, although there might be sustainability concerns. New data endorse the replacement of most high glycemic index (GI) foods with both whole grain and low GI cereal foods. As for beverages, low consumption not only of alcohol, but also of coffee and tea is associated with a reduced atherosclerosis risk while soft drinks show a direct relationship with CVD risk. This review provides evidence-based support for promoting appropriate food choices for atherosclerosis prevention in the general population.

We examined the relationships between the dietary inflammatory index (DII®), dietary habits and cardiovascular risk factor profiles in people with type 2 diabetes mellitus (T2DM). Energy-adjusted DII (E-DII™) scores were calculated from a Food Frequency Questionnaire in 2568 T2DM patients from different parts of Italy. Analyses were conducted according to quartiles of sex-specific E-DII scores. Higher, more pro-inflammatory, (quartile 4) E-DII scores were associated with overall poor quality of the diet characterised by higher content of refined carbohydrates, added sugars, saturated fat and cholesterol and lower unsaturated fat, fibre and polyphenols compared to quartile 1. Higher E-DII scores also were associated with higher waist circumference (105.4 vs. 103.5 cm; p = 0.002), triglycerides (154.6 vs. 146.1 mg/dL; p = 0.005), diastolic blood pressure (80.05 vs. 78.6 mmHg; p = 0.04) and lower HDL-cholesterol (45.3 vs. 47.4 mg/dL; p = 0.04). In conclusion, E-DII is a potent marker of overall quality of the diet and is associated with an unfavourable cardiovascular risk factor profile.

Exposure to artificial light at night (ALAN) has been associated with disruption of the circadian system, which has been pointed out to have detrimental effects on health. Exposure to outdoor ALAN is very frequent in industrialised countries due to nocturnal light pollution and the relevant involvement of the total workforce in shift work and night work. Ecological and epidemiologic studies highlight the association between exposure to ALAN and several diseases, mainly obesity and cancer. More recently, also indoor ALAN exposure has been investigated. Among several multifactorial mechanisms linking ALAN exposure and health risks, suppression of melatonin secretion plays a pivotal role leading to alterations in circadian rhythm patterns, that are detrimental in terms of appetite regulation, and dysfunctions in metabolic signalling and cell growth in cancer. In addition, gut dysbiosis, inflammation, hypovitaminosis D, imbalance in cytokine secretion and levels are responsible for the multiple relationship linking circadian dysregulation due to ALAN exposure and obesity, and cancer. Therefore, the current manuscript summarises human and basic studies pointing out the impact of ALAN exposure on health, mostly focusing on obesity and cancer. Based on extant evidence, prevention strategies for obesity and cancer should be prompted, targeting exposure to ALAN. (C) 2022 Published by Elsevier Ltd.

Fish consumption is associated with a reduced risk of cardiovascular diseases (CVDs) partly ascribed to the high content of long-chain (LC) n–3 PUFAs; however, not all fish types are equally rich in these components. To date, it is not clear whether the beneficial effects of fish consumption are shared by fatty and lean fish. Therefore, the aim of this meta-analysis was to synthesize knowledge regarding the relation between the intake of fatty fish or lean fish and the risk of cardiovascular events and all-cause mortality. We conducted a systematic search in PubMed, Web of Science, and Embase until May 2021 for full text with a prospective design involving humans providing data for the highest compared with the lowest fish consumption categories. Summary risk ratios (RRs) and 95% CIs were estimated using a random-effects model. Out of 1902 articles retrieved from the literature search, 19 reports met the criteria for inclusion in the meta-analysis. Altogether, studies on fatty fish comprised 1,320,596 person-years of follow-up, 20,531 incident coronary heart disease (CHD) cases, 9256 incident CVD cases, and 104,763 total deaths. Studies on lean fish comprised 937,362 person-years of follow-up, 21,636 incident CHD cases, 7315 incident CVD cases, and 16,831 total deaths. An inverse association was present for fatty fish with CHD incidence (RR: 0.92; 95% CI: 0.86, 0.97), CHD mortality (RR: 0.83; 95% CI: 0.70, 0.98), and total mortality (RR: 0.97; 95% CI: 0.94, 0.99). This was not the case for lean fish. The summary estimates for CVD incidence and mortality did not show significant association with both fatty fish and lean fish consumption. The study findings are innovative in highlighting that the health benefits so far linked to fish consumption are, in fact, driven by fatty fish.

The study compares the performance of the European Society of Cardiology (ESC) risk criteria and the Steno Type 1 Risk Engine (ST1RE) in the prediction of cardiovascular (CV) events.456 adults with type 1 diabetes (T1D) were retrospectively studied. During 8.5 ± 5.5 years of observation, twenty-four patients (5.2%) experienced a CV event. The predictive performance of the two risk models was evaluated by classical metrics and the event-free survival analysis.The ESC criteria show excellent sensitivity (91.7%) and suboptimal specificity (64.4 %) in predicting CV events in the very high CV risk group, but a poor performance in the high/moderate risk groups. The ST1RE algorithm shows a good predictive performance in all CV risk categories. Using ESC classification, the event-free survival analysis shows a significantly higher event rate in the very high CV risk group compared to the high/moderate risk group (p 0.0019). Using the ST1RE algorithm, a significant difference in the event-free survival curve was found between the three CV risk categories (p 0.0001).In T1D the ESC classification has a good performance in predicting CV events only in those at very high CV risk, whereas the ST1RE algorithm has a good performance in all risk categories.

We performed an umbrella review of dose-response meta-analyses of prospective studies reporting the incidence of type 2 diabetes associated with the consumption of animal-based foods. A systematic search was conducted in PubMed, Web of Science, Scopus, and Embase according to PRISMA. Thirteen meta-analyses are included in the study providing 175 summary risk ratio estimates. The consumption of 100 g/day of total or red meat, or 50 g/day of processed meat, were associated with an increased risk; RR and 95 % CI were respectively 1.20, 1.13-1.27; 1.22, 1.14-1.30 and 1.30, 1.22-1.39. White meat (50 g/day) was associated with an increased risk, but of lesser magnitude (RR 1.04, 95 % CI 1.00-1.08). A risk reduction was reported for 200 g/day of total dairy (RR 0.95, 95 % CI 0.92-0.98) or low-fat dairy (RR 0.96, 95 % CI 0.92-1.00) or milk (RR 0.90, 95 % CI 0.83-0.98), or 100 g/day of yogurt (RR 0.94, 95 % CI 0.90-0.98). No association with diabetes risk was reported for fish or eggs. In conclusions animal-based foods have a different association with diabetes risk. To reduce diabetes risk the consumption of red and processed meat should be restricted; a moderate consumption of dairy foods, milk and yogurt, can be encouraged; moderate amounts of fish and eggs are allowed.

Aims The educational program implemented at the Pratola Serra (Avellino, Italy) facility of the company FCA (Fiat Chrysler Automobiles), had as its goal to raise awareness among people to adopt behaviors inspired by the principles of a Mediterranean diet, physical activity and prevention of the main cardiovascular risk factors. Methods The educational program was implemented in two different ways in order to compare, according to an intervention-control scheme, the performance of the subgroups and the effect of the types of intervention. On both groups measurements of the vital parameters were carried out and compared by means of statistical probabilistic tests. Results The educational intervention was shown to be effective in: encouraging healthy food choices both in the workplace and at home (with a statistically significant reduction in caloric intake, animal protein, saturated fatty acids, cholesterol and glycemic load and an increase in vegetable proteins), significantly increasing physical activity and reducing body weight, body mass index, waist circumference, total cholesterol, LDL cholesterol and blood glucose in the participants. Conclusions The educational campaign proved effective in increasing the well-being of the participants, confirming the effectiveness of a multifactorial intervention based on the promotion of a dietary model rather than individual foods.

Objectives: Little is known about the specific comorbidities contributing to higher costs in patients with type-2 diabetes mellitus (T2DM), particularly in older cases. We aimed to evaluate the prevalence, type, and cost of comorbidities occurring in older T2DM patients versus older non-T2DM patients, and the factors associated with high cost (HC) T2DM patients.Methods: Retrospective cohort study using information from the Campania Region healthcare database. People aged ≥65 years who received ≥2 prescriptions for antidiabetic drugs were identified as “T2DM patients.” Comorbidities among T2DM and non-T2DM groups were assessed through the RxRiskV Index (modified version). T2DM individuals were classified according to the total cost distribution as HC or “non-high cost.” Two sub-cohorts of HC T2DM patients were assessed: above 90th and 80th percentile of the total cost. Age- and sex-adjusted logistic regression models were created.Results: Among the T2DM cohort, concordant and discordant comorbidities occurred significantly more frequently than in the non-T2DM cohort. Total mean annual cost per T2DM patient due to comorbidities was €7,627 versus €4,401 per non-T2DM patient. Among T2DM patients identified as being above 90th and 80th percentiles of cost distribution, the total annual costs were >€19,577 and >€2,563, respectively. The hospitalization cost was higher for T2DM cases. Strongest predictors of being a HC T2DM patient were having ≥5 comorbidities and renal impairment.Conclusion: HC patients accrued >80% of the total comorbidities cost in older T2DM patients. Integrated care models, with holistic and patient-tailored foci, could achieve more effective T2DM care.

Aims: Non-Alcoholic Fatty Liver Disease (NAFLD) and type 2 diabetes (T2D) share pathophysiological mechanisms and possible therapeutic strategies. We evaluated the effects of 1-year treatment with pioglitazone or sulphonylureas on indirect indices of NAFLD in people with T2D and the role of insulin-resistance and glucotoxicity in determining these effects. Methods: Patients with T2D (n = 195) aged 50–75 years, poorly controlled with metformin 2 g/day, were randomly allocated to add-on pioglitazone (n = 98) or sulphonylureas (n = 97) within the TOSCA.IT trial. Plasma insulin, glucose, and liver enzymes were measured at baseline and after 1-year. Indirect indices of NAFLD (Liver Fat Equation [LFE], Hepatic Steatosis Index [HSI], and Index of NASH [ION]), and insulin resistance (HOMA-IR, Visceral Adiposity Index [VAI] and adipose tissue Insulin Resistance [ADIPO-IR]) were calculated. Results: Indices of NAFLD improved after pioglitazone, but not after sulphonylureas; differences between changes (1-year minus baseline) were respectively: -1.76 ± 3.84 vs. 0.28 ± 3.75 for LFE; -1.35 ± 2.78 vs. -0.27 ± 2.63 for HSI; -9.75 ± 43 vs. 3.24 ± 31 for ION; p < 0.05 for all. Indices of insulin resistance decreased after pioglitazone, but not after sulphonylureas: -0.95 ± 4.57 vs. 0.37 ± 3.34 for HOMA-IR, p = 0.032; -1.25 ± 4.11 vs. 1.36 ± 5.43 for ADIPO-IR, p = 0.001; -0.53 ± 1.88 vs. 0.03 ± 2.36 for VAI, p = 0.074. Changes in NAFLD indices were similar with different doses of pioglitazone (15, 30, or 45 mg/day), and were independent of blood glucose control. Conclusions: One-year treatment with pioglitazone even at low dosage significantly improved liver steatosis and inflammation, systemic and adipose tissue insulin resistance in patients with T2D. The beneficial effects of pioglitazone on NAFLD were independent of blood glucose control.

Background: We evaluate whether the Pro12Ala polymorphism of peroxisome proliferator-activated receptor γ2 (PPARγ2) has a role in the progression of diabetes by modulating the occurrence of treatment failure to glucose-lowering drugs. Methods: We studied 215 patients with type 2 diabetes participating in the Thiazolidinediones Or Sulphonylureas and Cardiovascular Accidents Intervention Trial study. All participants were insufficiently controlled (glycated haemoglobin [HbA1c] 7.0%-9.0%) with metformin 2 g/day and were randomly allocated to add-on pioglitazone or a sulfonylurea. Treatment failure was defined as HbA1c ≥8% on two consecutive visits, 3 months apart. Results: Carriers or non-carriers of the polymorphism had similar age, body mass index, and diabetes duration. Ala carriers had lower fasting plasma insulin, better insulin sensitivity (Homeostasis Model Assessment [HOMA]2-%S), and worse beta cell secretion (HOMA2-%B) than non-carriers. During 24 months of follow-up, 32.5% among the Ala carriers and 8.6% among non-carriers (P < 0.001) developed treatment failure with a cumulative incidence of 18.6 vs 4.6/100 person-years. Those patients who developed treatment failure were older, had a younger age at diabetes diagnosis (48 ± 10 vs 52 ± 7 years; P = 0.032), higher HbA1c (8.1 ± 0.5 vs 7.7 ± 0.5%; P < 0.001), and lower HOMA2-%B (30 ± 12 vs 46 ± 29; P = 0.015) at study entry, as compared to those who did not develop treatment failure. At multivariate analysis, the Pro12Ala polymorphism was significantly associated with treatment failure (hazard ratio [HR] 4.45; 95% confidence interval [CI] 1.79-11.1; P < 0.001); HbA1c at study entry was the other independent predictor of failure in this study population. Conclusion: The Pro12Ala polymorphism is associated with a greater insulin sensitivity, reduced beta cell function and a substantially increased risk of treatment failure.

Aims Cardiovascular diseases are the main cause of death in Europe. Food choices represent the most important factors undermining health and well-being; they account for as much as half of all CVD deaths in Europe. The aim of this viewpoint is to evaluate food choices of the European population and their temporal trends in relation to possible effects on the cardiovascular disease risk. Data synthesis The CVD death rate attributable to diet-related factors has fallen in Europe over the last 25 years; however, the pace of the reduction has slowed down in the last ten years. In parallel, in the last decade unfavorable changes in the dietary habits associated with CVD risk have occurred. Conclusions A mismatch exists between the available evidence on the health-promoting potential of the diet and the relatively modest and inconsistent improvements of dietary habits in the European population observed in recent years. Nutritional education alone will not be enough to improve the lifestyle of people in Europe. Policy options to be considered to reach this aim should necessarily include also initiatives for facilitating production, marketing, availability and affordability of healthy foods in each and every European country.

Aims To document in recent cohorts the degree of control of major cardiovascular (CV) risk factors according to diabetes status and prior CV disease in different settings. Methods We studied men and women aged 50–75 years of whom 3028 with type 2 diabetes mellitus (T2DM) managed at diabetes clinics participants of the TOSCA.IT (NCT00700856) study recruited in 2008–2014; 742 with T2DM managed mainly in primary care and 6753 without diabetes participating in the Moli-sani (NCT03242109) study and recruited in 2005–2010 from an adult general population. Results Among people without a prior CV event people with diabetes managed at diabetes clinics have lower LDL-cholesterol and blood pressure and a more frequent use of lipid-lowering and antihypertensive medications as compared to people with diabetes managed mainly in primary care and to people without diabetes. The proportions achieving the recommended treatment targets are respectively 47.4% vs 33.4% vs 29.5% for LDL-cholesterol and 42.6% vs 9.5% vs 47.4% for blood pressure. Figures for the participants with prior CV events were 26.8% vs 15.1% vs 42.5% for LDL-cholesterol and 43.8% vs 8.5% vs 43.6% for blood pressure. Conclusions The study documents that in modern cohorts a large proportion of people with or without diabetes does not achieve the treatment targets for LDL-cholesterol and blood pressure, both in primary and secondary CV prevention. People with diabetes attending diabetes clinics achieve a better control of major CV risk factors than those managed mainly in primary care, thus highlighting the relevant role of a structured model of care.

Backgrounds and aims To investigate relevant indicators of quality of care in a large population-based sample of people with diabetes representative of clinical practice in Italy in 2018. Methods and results We analyzed data from 11,300,750 subjects. All administrative healthcare claims collected in 2018 were scrutinized to identify subjects with diabetes and investigate several indicators of quality of care. Subjects with diabetes were identified by anti-hyperglycemic drug prescriptions, disease-specific co-payment exemption and hospital discharge codes. Indicators of quality of care pertained to monitoring (HbA1c, creatinine, lipid profile, microalbuminuria, eye examination, ECG, ultrasonography of carotid and lower limb arteries) and diabetes treatment (anti-hyperglycemic agents in subjects with cardiovascular disease, CVD). Subjects attending and nonattending Diabetes Clinics were compared. We identified 697,208 individuals with diabetes. HbA1c was assessed at least once in the year in 62.7%, creatinine in 62.3%, total cholesterol in 59.6%, microalbuminuria in 34.3%. Frequency of eye examination was 8.2%, ECG 23.5%, carotid ultrasonography 14.3%, lower limb ultrasonography 7.6%. Among anti-hyperglycemic drugs, SGLT-2 inhibitors were prescribed to ~5% and GLP-1 receptor agonists to ~5% although the proportion of subjects with CVD was ~45%. Subjects attending Diabetes Clinics had higher figures for all these monitoring and treatment indicators. Conclusions The implementation of national and international guidelines regarding disease monitoring and treatment is far from being satisfactory, especially among subjects nonattending Diabetes Clinics. Further efforts and investments are needed for better disseminating guidelines, more efficaciously engaging healthcare professionals and more strongly empowering the healthcare system to improve diabetes care.

IntroductionDiabetes is a highly prevalent disease worldwide and represents a challenge for patients and healthcare systems. This population-based study evaluated diabetes burden in Italy in 2018 by assessing all aspects of outpatient and hospital care.Research design and methodsWe investigated data of 11 300 750 residents in local health districts contributing to ARNO Diabetes Observatory (~20% of Italian inhabitants). All administrative healthcare claims were analyzed to gather information on access to medical resources. Subjects with diabetes, identified by antihyperglycemic drug prescriptions, disease-specific copayment exemption and hospital discharge codes, were compared with age, sex and residency-matched non-diabetic individuals.ResultsWe identified 697 208 subjects with ascertained diabetes, yielding a prevalence of 6.2% (6.5% in men vs 5.9% in women, p2-fold higher in subjects with diabetes, mainly driven by hospitalizations and outpatient care related to chronic complications rather than to glucose-lowering drugs, diabetes-specific devices, or metabolic monitoring.ConclusionsThe burden of diabetes in Italy is particularly heavy and, as a systemic disease, it includes all aspects of clinical medicine, with consequent high expenses in all areas of healthcare.

Background: Pasta is a refined carbohydrate with a low glycemic index. Whether pasta shares the metabolic advantages of other low glycemic index foods has not really been investigated. The aim of this study is to document, in people with type-2 diabetes, the consumption of pasta, the connected dietary habits, and the association with glucose control, measures of adiposity, and major cardiovascular risk factors. Methods: We studied 2562 participants. The dietary habits were assessed with the European Prospective Investigation into Cancer and Nutrition (EPIC) questionnaire. Sex-specific quartiles of pasta consumption were created in order to explore the study aims. Results: A higher pasta consumption was associated with a lower intake of proteins, total and saturated fat, cholesterol, added sugar, and fiber. Glucose control, body mass index, prevalence of obesity, and visceral obesity were not significantly different across the quartiles of pasta intake. No relation was found with LDL cholesterol and triglycerides, but there was an inverse relation with HDL-cholesterol. Systolic blood pressure increased with pasta consumption, but this relation was not confirmed after correction for confounders. Conclusions: In people with type-2 diabetes, the consumption of pasta, within the limits recommended for total carbohydrates intake, is not associated with worsening of glucose control, measures of adiposity, and major cardiovascular risk factors.

TOSCA.IT is an institutional, non-industry-supported, head-to-head study comparing long term cardiovascular effects, efficacy and safety of two antidiabetes drugs (pioglitazone vs sulphonylureas) used in combination with metformin in patients with type 2 diabetes mellitus. The study results show that in the absence of clinically evident cardiovascular disease both treatment strategies represent suitable alternatives; however, in consideration of the greater durability of the metabolic effects, the lower risk of hypoglycemia and the potential benefit on atherosclerotic cardiovascular disease, the combination of metformin and pioglitazone may be considered as the preferential therapeutic option. In this review the study is critically evaluated against the background of the evidence accumulated over the last decade on the impact of different glucose lowering drugs on cardiovascular events in people with type 2 diabetes.

Context Hypoglycemic drugs with proven cardiovascular (CV) benefits are recommended for patients with type 2 diabetes and CV disease. Whether the beneficial effects extend to those at lower risk remains unclear. Aim We investigated the long-term CV effects of pioglitazone or sulfonylureas (SUs) across the spectrum of pretreatment CV risk. Methods Among 2820 participants of the TOSCA.IT trial, four subgroups with different risk of outcome-a composite of all-cause death, nonfatal myocardial infarction, nonfatal stroke, urgent coronary revascularization-were identified by the RECursive Partitioning and AMalgamation (RECPAM) method. Within each group, the effect of SUs or pioglitazone on the outcome was evaluated. Results Sex was the first splitting variable, followed by urinary albumin-to-creatinine ratio (UACR) (>9 mg/g or ≤9 mg/g) and body mass index (BMI) (>28.7 or ≤28.7 kg/m2). Female patients had the lowest risk (reference); male patients with UACR >9 mg/g and BMI >28.7 kg/m2 had the highest risk [hazard ratio (HR), 5.58; 95% CI, 3.32 to 9.69]. Patients in this group present a cluster of conditions suggestive of marked insulin resistance (higher BMI, waist circumference, triglycerides, blood pressure, and UACR and lower high-density lipoprotein cholesterol) than the other groups. Treatment with pioglitazone in this group was associated with a significantly lower occurrence of the outcome than SUs (HR, 0.48; 95% CI, 0.25 to 0.76). No significant difference between study treatments was observed in the other RECPAM classes. Conclusions It is possible to identify patients with type 2 diabetes early in the stage of their disease and who are largely free from evident CV disease in whom add-on pioglitazone to metformin confers CV protection as compared with SUs.

Aims: Type 2 diabetes (DM2) is associated to oxidative modifications of high-density lipoproteins (HDL), which can interfere with their function. Pioglitazone has proved effective in raising HDL cholesterol (HDL-C) and lowering small dense low-density lipoprotein (LDL), but no clinical studies have examined its effect on lipoprotein oxidation in patients with DM2. Methods: We assessed the effect of pioglitazone vs glimepiride after 1 year on HDL oxidation, expressed as relative abundance of peptides containing Met 112 O in ApoA-I (oxApoA-I) estimated by mass spectrometry (MALDI/TOF/TOF), in 95 patients with DM2. The oxLDL and AGE were quantified by ELISA. Results: Patients receiving pioglitazone showed a significant increase in the concentration of ApoA-I (Δ = 7.2 ± 14.8 mg/dL, p < 0.02) and a reduction in oxApoA-I (Δ = − 1.0 ± 2.6%, p < 0.02); this reduction was not significantly different from glimepiride. oxLDL showed a slight, but not significant increase in both treatment groups. Regression analysis showed a correlation between ΔoxApoA-I and ΔAGE (r = 0.30; p = 0.007) in all patients, while both of these parameters were unrelated to changes in HbA1c, HDL-C, duration of illness, or use of statins. Conclusions: Long-term treatment with pioglitazone was effective in reducing the oxidation of HDL, but not LDL in patients with DM2, while glimepiride didn’t. This finding seems to be associated to the change of glyco-oxidation status, not to any improvement in glycemic control or lipid profile. Trial registration: NCT00700856, ClinicalTrials.gov Registered June 18, 2008.

Purpose: The optimal macronutrient composition of the diet for the management of type 2 diabetes is debated, particularly with regard to the ideal proportion of fat and carbohydrates. The aim of the study was to explore the association of different proportions of fat and carbohydrates of the diet—within the ranges recommended by different guidelines—with metabolic risk factors. Methods: We studied 1785 people with type 2 diabetes, aged 50–75, enrolled in the TOSCA.IT Study. Dietary habits were assessed using a validated food-frequency questionnaire (EPIC). Anthropometry, fasting lipids, HbA1c and C-reactive protein (CRP) were measured. Results: Increasing fat intake from

Background and aims: In the present population-based study, we aimed to describe the per patient annual healthcare cost of people with diabetes in 2007-2012, to assess the relative burden of diabetes complications and other potential determinants on healthcare costs in the 2012 cohort, and to describe and analyse the determinants of the cost of incident cases diagnosed in 2012. Methods and results: We analysed data from a retrospective cohort of residents in four Italian areas that were served by Local Health Units participating in the ARNO Observatory. Per patient annual healthcare costs (Euros) were estimated as the sum of all the resources supplied during that year (drugs, outpatient care, and hospitalisations). The mean per patient annual healthcare cost increased from €2752 in 2007 to €3191 in 2010, before decreasing to €2791 in 2012. The largest component of these costs was represented by hospitalisations (around €1550, on average; 51.7% of total cost), followed by outpatient care (€422; 14.6%) and drugs (€973; 33.7%). In 2012, the most relevant cost determinants were chronic diabetes complications, with an additional cost due to nephropathy/end stage renal disease (€4683), amputations (€5042), lower extremity revascularization (€4808), and cerebrovascular diseases (€3861). Costs associated with incidence cases were higher than those associated with prevalent. Conclusion: The present study provides evidence on the excess of healthcare costs due to diabetes complications in both prevalent and incident cases.

Aims: To assess whereas prevalence, treatment and direct costs of drug-treated dia-betes were similar in migrants and in people of Italian citizenship under the universalistic Italian health care system. Methods and results: Drug-treated diabetic individuals were identified in the population-based multiregional ARNO Observatory on the basis of 2010 prescriptions. Migrants were identified by the country-of-birth code on the fiscal identification code. Diabetes prevalence was calculated for Italians (n Z 7,328,383) and migrants (n Z 527,965). To assess the odds of migrants of having diabetes compared to Italians, we individually matched all migrants to Italians for major con-founders (age, sex and place of residence). Finally, all migrants with diabetes were individually matched for confounders to Italians with diabetes to compare prescriptions, hospitalization rates, services use and direct costs for the National Health System. We identified 368,797 sub-jects with diabetes among Italians and 10,336 among migrants, giving prevalence of 5.03% and 1.96%, respectively. Migrants with diabetes were younger than Italians (52 13 years vs. 68 14 years, P < 0.001); after matching, their risk of disease was higher (odds ratio, 1.55, 95% confidence interval, 1.50e1.60). The total cost was 27% lower in migrants, due to lower cost of drugs (29%), hospital admission (27%) and health services (22%). The number of packages/treated person-year of all glucose-lowering drugs was also lower in migrants (15%) (P < 0.001). Conclusions: Compared to subjects of Italian ancestry, migrants to Italy show a higher risk of diabetes but less intense treatment. Inequalities in health care use are likely and are maintained also in a universalistic system.

OBJECTIVE To evaluate the feasibility and effectiveness of an intensive, multifactorial cardiovascular risk reduction intervention in a clinic-based setting. RESEARCH DESIGN AND METHODS The study was a pragmatic, cluster randomized trial, with the diabetes clinic as the unit of randomization. Clinics were randomly assigned to either continue their usual care (n = 5) or to apply an intensive intervention aimed at the optimal control of cardiovascular disease (CVD) risk factors and hyperglycemia (n = 4). To account for clustering, mixed model regression techniques were used to compare differences in CVD risk factors and HbA1c. Analyses were performed both by intent to treat and as treated per protocol. RESULTS Nine clinics completed the study; 1,461 patients with type 2 diabetes and no previous cardiovascular events were enrolled. After 2 years, participants in the interventional group had significantly lower BMI, HbA1c, LDL cholesterol, and triglyceride levels and significantly higher HDL cholesterol level than did the usual care group. The proportion of patients reaching the treatment goals was systematically higher in the interventional clinics (35% vs. 24% for LDL cholesterol, P = 0.1299; 93% vs. 82% for HDL cholesterol, P = 0.0005; 80% vs. 64% for triglycerides, P = 0.0002; 39% vs. 22% for HbA1c, P = 0.0259; 13% vs. 5% for blood pressure, P = 0.1638). The analysis as treated per protocol confirmed these findings, showing larger and always significant differences between the study arms for all targets. CONCLUSIONS A multifactorial intensive intervention in type 2 diabetes is feasible and effective in clinical practice and it is associated with significant and durable improvement in HbA1c and CVD risk profile.

The study explores the degree of control of hyperglycaemia and cardiovascular (CV) disease risk factors in men and women with type 2 diabetes and the impact thereon of obesity, central adiposity, age and use of medications.A cross-sectional survey was conducted at 10 hospital-based outpatients diabetes clinics. 1297 men and 1168 women with no previous CV events were studied. Women were slightly (only one year) older and more obese than men: average BMI was respectively 30.7 ± 5.7 vs 28.6 ± 4.1 kg/m(2) (p0.001), and prevalence of abdominal obesity was 86% vs 44% (p0.001). Women smoked less, but had higher HbA1c, LDL cholesterol, non-HDL cholesterol, systolic blood pressure and serum fibrinogen than men. Accordingly optimal targets for HbA1c (7%), LDL cholesterol (100 mg/dL), HDL cholesterol (40 for men,50 for women, mg/dL), and systolic blood pressure (130 mmHg) were less frequently achieved by women than men (respectively 33.8% vs 40.2%; 14.6% vs 19.2%; 34.1% vs 44.5%; 68.8% vs 72%; p0.05 for all). Findings were confirmed after stratification for waist circumference (or ≥ 88 cm for women;or ≥ 102 cm for men), BMI (or ≥ 25 kg/m(2)) or age (or ≥ 65 years). As for treatment, women were more likely than men to take insulin, alone or in combination with oral hypoglycaemic drugs, to be under anti-hypertensive treatment, whereas the use of lipid lowering drugs was similar in men and women.Control of hyperglycaemia and major CVD risk factors is less satisfactory in women than men. The gender disparities are not fully explained by the higher prevalence of total and central obesity in women; or by a less intensive medical management in women.

The paper presents a post-hoc analysis of the intensity of dyslipidaemia care operated in the first 2 years of Multiple-Intervention-in-type-2-Diabetes.ITaly (MIND.IT) study.MIND.IT is a multicentric, randomized, two-parallel arm trial involving 1461 type 2 diabetic patients at high cardiovascular (CV) risk. The study compares the usual care (UC) of CV prevention with a multifactorial intensive care (IC) approach aiming at achieving target values for the main CV risk factors according to a step-wise treat-to-target approach.Proportion of patients on target for low-density lipoprotein cholesterol (LDL-C) was about 10% at baseline and increased significantly more with IC than UC (43 vs. 27%; p 0.001). However, the majority (57%) of patients, in this intended intensively treated cohort, failed to achieve the proposed target. Average LDL-C decreased from 144 ± 35 to 108 ± 31 mg/dl with IC and from 142 ± 28 to 118 ± 32 with UC (p-for-interaction0.0001). IC was associated with a significantly greater increase in statin prescription and lower withdrawal from treatment than UC (43 vs. 11% and 28 vs. 61%, respectively; both p 0.001). However, the new treatments were characterized in both groups by the use of low starting doses (≤ 10 mg of atorvastatin, equivalent dose in more than 90% of patients) without increase in case of missed target.The application of a multifactorial treat-to-target intervention is associated with a significant improvement in LDL-C beyond usual practice. However, the change in LDL-C appears to be more related to an increased number of treated patients and a decreased treatment withdrawal than to a true treat-to-target approach.

The role for lifestyle modifications to correct dyslipidemia(s) is reviewed. Dietary composition is crucial. Replacing saturated fat with MUFA or n-6 PUFA lowers plasma low-density lipoproteins (LDL) cholesterol and ameliorates the LDL/HDL ratio. Replacing saturated fat with carbohydrates has diverging effects due to the heterogeneity of carbohydrate foods. Diets rich in refined carbohydrates increase fasting and postprandial triglycerides, whereas the consumption of fiber-rich, low GI foods lowers LDL cholesterol with no detrimental effects on triglycerides. The role of polyphenols is debated: available evidence suggests a lowering effect of polyphenol-rich foods on postprandial triglycerides. As for functional foods, health claims on a cholesterol lowering effect of psyllium, beta-glucans and phytosterols are accepted by regulatory agencies. The importance of alcohol intake, weight reduction, and physical activity is discussed. In conclusion, there is evidence that lifestyle affects plasma lipid. A multifactorial approach including multiple changes with additive effects is the best option. This may also ensure feasibility and durability. The traditional Mediterranean way of life can represent a useful model.

Background and aims: Diabetic women have a more adverse plasma lipid profile than men. Sex differences in dietary habits may play a role, but are little investigated. The study evaluates the quality of diet, adherence to the nutritional recommendations of the Diabetes and Nutrition Study Group and their relation with plasma lipid in men and women with diabetes. Methods and results: We studied 2573 people, aged 50e75, enrolled in the TOSCA.IT study (clinicaltrials.gov; NCT00700856). Plasma lipids were measured centrally. Diet was assessed with a semi-quantitative food frequency questionnaire.Women had a more adverse plasma lipid profile than men.Women consumed significantly more legumes, vegetables, fruits, eggs, milk, vegetable oils, and added sugar, whereas men consumed more starchy foods, soft drinks and alcoholic beverages. This stands for a higher proportion (%) of energy intake from saturated fat and added sugar (12.0 2.4 vs 11.5 2.5 and 3.4 3.2 vs 2.3 3.2, P < 0.04), and a higher intake of fiber (11.2 2.8 vs 10.4 2.6 g/1000 Kcal/day) in women. Adherence to the recommendations for saturated fat and fiber consumption was associated with significantly lower LDL-cholesterol regardless of sex. Adherence to the recommendations for added sugars was associated with significantly lower triglycerides and higher HDL-cholesterol in men and women. Conclusions: Men and women with diabetes show significant differences in adherence to nutritional recommendations, but sex differences in plasma lipid profile are unlikely to be explained by nutritional factors. Adherence to the nutritional recommendations is associated with a better plasma lipid profile regardless of sex, thus reinforcing the importance of substituting saturated for unsaturated fat sources, increasing fiber and reducing added sugar intake.

To assess temporal trend in incidence (2003-12) and prevalence (2002-12) of type 1 diabetes in children and young adults, direct costs and selected indicators of quality of care under the coverage of the universalistic Italian National Health System (NHS).The ARNO Observatory, a healthcare monitoring system based on administrative data, identified a population-based multiregional cohort of subjects aged 0-29 years. Type 1 diabetes was defined by at least two prescriptions of insulin over 12 months and continuous insulin-treatment in the following year. Indicators of quality of care and directs costs were assessed in persons with diabetes and in people without diabetes, individually matched for age, gender and health unit (1:4 ratio). We identified 2357 incident cases of type 1 diabetes aged 0-29 years (completeness of ascertainment, 99%). Incidence rates were similar in ages 0-14 (15.8, 95% CI 14.9-16.8) and 15-29 years (16.3, 15.4-17.2), with no significant trend. Prevalence increased from 137 to 166.9/100,000, particularly in the age 15-29 years. Direct costs accounted for € 2117 in persons with diabetes and € 292 in control individuals. A statistically significant decreasing trend in hospitalization for acute complications was evident (p 0.001), which was almost completely due to ketoacidosis. People with at least one HbA1c measurement over the year were 48.5%.We showed high incidence and increasing prevalence of type 1 diabetes in young adults in Italy, which impact on direct costs under the universalistic coverage of the NHS.

Background and aims In the present population-based study, we aimed to describe the per patient annual healthcare cost of people with diabetes in 2007–2012, to assess the relative burden of diabetes complications and other potential determinants on healthcare costs in the 2012 cohort, and to describe and analyse the determinants of the cost of incident cases diagnosed in 2012. Methods and results We analysed data from a retrospective cohort of residents in four Italian areas that were served by Local Health Units participating in the ARNO Observatory. Per patient annual healthcare costs (Euros) were estimated as the sum of all the resources supplied during that year (drugs, outpatient care, and hospitalisations). The mean per patient annual healthcare cost increased from €2752 in 2007 to €3191 in 2010, before decreasing to €2791 in 2012. The largest component of these costs was represented by hospitalisations (around €1550, on average; 51.7% of total cost), followed by outpatient care (€422; 14.6%) and drugs (€973; 33.7%). In 2012, the most relevant cost determinants were chronic diabetes complications, with an additional cost due to nephropathy/end stage renal disease (€4683), amputations (€5042), lower extremity revascularization (€4808), and cerebrovascular diseases (€3861). Costs associated with incidence cases were higher than those associated with prevalent. Conclusion The present study provides evidence on the excess of healthcare costs due to diabetes complications in both prevalent and incident cases.

OBJECTIVE—We explore the relationship among BMI, habitual diet, and the Pro12Ala polymorphism in the peroxisome proliferator–activated receptor (PPAR)γ2. RESEARCH DESIGN AND METHODS—The Pro12Ala variant was characterized in 343 unrelated type 2 diabetic patients who were consecutively seen at the outpatient clinic of a health district of the province of Naples. Anthropometric and laboratory parameters were measured; habitual diet was assessed by a validated semiquantitative food frequency questionnaire. RESULTS—The overall frequency of Ala12 was 12% (n = 42). BMI was significantly higher in Ala carriers than non-Ala carriers, whereas total daily energy intake or macronutrient composition of the diet were similar in the two groups. For further analysis, participants were stratified according to genotype and sex-specific quartiles of energy intake. BMI increased in both genotype groups with increasing energy intake (P < 0.03). BMI was similar in Ala carriers and non-Ala carriers (30.0 vs. 30.1 kg/m2, P > 0.10) in the lower quartile of energy intake but significantly higher in Ala carriers in the upper quartile (36.0 vs. 32.1 kg/m2, P < 0.001). Average daily energy intake and diet composition were comparable within each quartile for carriers or noncarriers of the Ala allele. Relative to the noncarriers, Ala carriers had a significantly lower energy intake per kilogram body weight, thus suggesting that the Ala allele is associated with a higher food efficiency. The confounding role of medications, glucose control, and physical exercise was ruled out. CONCLUSIONS—This study provides evidence of a differential susceptibility to fat accumulation, and, hence, weight gain, in response to habitual high energy intake for Ala carriers compared with Pro/Pro homozygotes.

The aim of this article is to evaluate food properties able to influence specific physiological targets that may be helpful for the prevention and management of overweight and diabetes.Observational and intervention studies have clearly shown that type 2 diabetes can be prevented by lifestyle measures, including reduced energy intake to induce a modest but sustained weight reduction, together with changes in diet composition.Foods can be regarded as functional if proven to affect beneficially one or more target functions in the body, beyond adequate nutritional effects, in a way relevant to improved state of health and well-being, reduction of risk of diseases, or both. Functional foods might have a particularly high impact for prevention or treatment of overweight and diabetes for which, more than in many other fields, the link between nutrition, biological responses and diseases is clearly established. Functional foods for obesity should be able to influence the energy balance equation regulated by the control of energy intake or of energy dissipated as heat (thermogenesis). For prevention of type 2 diabetes, several unmodified foods with functional properties have already been identified (low saturated fat products, vegetables, fruit, wholegrain foods, low glycemic index starchy foods). Overall, the available evidence on functional foods so far identified in this field is incomplete: the major gap is the lack of diet-based intervention trials of sufficient duration to be relevant for the natural history of diseases like overweight and diabetes.

Background There is no definite consensus on which indexation of left ventricular mass (LVM) should be used to better identify left ventricular hypertrophy (LVH). Left ventricular mass has been adjusted to height, to height 2.7 (h 2.7 ) and to body surface area (BSA). The aims of the present study were to evaluate the prevalence of LVH according to different indexations and different cut-offs and to identify the most useful indexation of LVM to detect hypertension-related LVH. Methods Echocardiographic LVH was defined as LVM to h 2.7 , LVM to BSA, LVM to height, LVM values in the upper 5th percentile of our gender-related LVM distribution, using different partition values suggested in previous population-based studies. Results Prevalence of LVH in the general population was 32% using the less restrictive criterion (LVH 49.2/46.7 g/m 2.7 ), 15% with the criterion of LVH 116/104 g/m 2 , and 3.8% with the most restrictive one (LVH 134/110 g/m 2 ). Prevalence of LVH in hypertensive subjects was almost twice than in normotensive subjects with all criteria. Only 20 subjects out of the 707 evaluated were found to have LVH with all six criteria. In multiple regression analysis SBP was independently associated with nonindexed LVM and was indexed to both BSA and h 2.7 . On the other hand, fat-free mass was a poweful predictor of nonindexed LVM or of LVM to BSA, whereas body mass index was the strongest predictor of LVM to h 2.7 . Conclusions The indexation of LVM to BSA, possibly with the cut-off of LVH 116/104, is probably the best criterion for identifying blood pressure–related LVH.
