ABSTRACT
Turmeric is a spice widely used in China, Southeast Asia, and in traditional Ayurvedic medicine. Its safety profile and efficacy as an antioxidant, anti-inflammatory, antimicrobial, antitumor, antidiabetic, and anti-obesity agent have led to extensive research into its potential role in preventing and treating metabolic diseases. The active compound in turmeric is curcumin, which exhibits low systemic bioavailability after oral administration. However, it is detectable in the gut, where it bidirectionally interacts with the gut microbiota (GM), which plays a crucial role in maintaining host health. The favorable effects of curcumin, particularly its hypoglycemic properties, are linked to alteration in intestinal dysbiosis observed in type 2 diabetes mellitus and metabolic syndrome patients. Restoration of the eubiotic GM may contribute to glycemic homeostasis. Preclinical and clinical studies have demonstrated the involvement of the GM in the regulation of glucose and lipid metabolism. Although the underlying mechanism remains incompletely understood, intestinal dysbiosis is associated with insulin resistance, hyperglycemia, and low-grade inflammation. In the present overview, we summarize the biological properties of curcumin, focusing on its link with GM and, therefore, on its potential role in metabolic diseases.

In determining the so-called "body burden", hair has been widely accepted for assessing toxic element exposure. However, its role in assessing essential elements is controversial. This study investigates the possible relationship between hair minerals, metabolic syndrome (MetS) and cardiovascular (CV) risk in non-occupationally exposed subjects with overweight-obesity. Ninety-five voluntary participants (aged 51 ± 12) were recruited in Northern Italy. Hair samples were collected and analysed via inductively coupled plasma mass spectrometry; the total toxicity index (TI) was calculated as well. To evaluate cardiovascular risk factors in the presence or absence of MetS, the following factors were considered via the innovative artificial neural network (ANN) method Auto-CM: hair mineralograms (31 elements) and 25 variables including blood pressure, anthropometric parameters, insulin resistance and biochemical serum markers assessing inflammation. The Framingham risk score, fatty liver index (FLI), visceral adiposity index and CV risk scores were also taken into consideration. As shown by the semantic map, which was subsequently confirmed by an activation and competition system (ACS), obesity parameters are strictly associated with CV risk factors, TI and inflammation; meanwhile, the single mineral elements seem to be unimportant. Data obtained via ANN demonstrate that MetS may be at least partly mediated by altered mineral levels also in the presence of obesity and that waist circumference is a crucial point to be monitored rather than BMI alone. Furthermore, the mineral body burden is one of the important factors for CV risk.
ABSTRACT
Unhealthy dietary habits determined during childhood may represent a risk factor to many of the chronic non-communicable diseases (NCDs) in adulthood. Mediterranean Diet (MD) adherence in children and adolescents (8-16 years) living in Spain was investigated using the KIDMED questionnaire in a comparative analysis of two cross-sectional nationwide representative studies: enKid (1998-2000, n = 1001) and PASOS (2019-2020, n = 3540). Taking into account the educational level of pupils, as well as the characteristics of the place of living, a significant association was found between a KIDMED score ≥ 8 (optimal MD adherence) and primary education as well as residency in an area of <50,000 inhabitants, while living in the southern regions was associated with non-optimal MD adherence (p < 0.001). Participants of the 2019-2020 study showed an increase in the consumption of dairy products (31.1% increase), pasta/rice (15.4% increase), olive oil (16.9% increase), and nuts (9.7% increase), as well as a decreased sweets and candies intake (12.6% reduction). In contrast, a significantly lower MD adherence was found when comparing the 2019-2020 (mean ± SE: 6.9 ± 0.04) and the 1998-2000 study (7.37 ± 0.08); p < 0.001), due to less consumption of fish (20.3% reduction), pulse (19.4% reduction), and fruits (14.9% reduction), and an increased intake of commercial goods/pastries or fast-food intake (both 19.4% increase). The lowest adherence was recorded for adolescents also in the most recent study, where 10.9% of them presented a KIDMED score ≤ 3. This study shows that eating habits are deteriorating among Spanish children and adolescents. Such findings point out the urgency of undertaking strong measures to promote the consumption of healthy, sustainable, and non-ultra-processed food, such as those available in an MD, not only at a scientific and academic level, but also at a governmental one.

The hypoglycemic properties of curcumin supplements in therapeutic doses are well-known and may represent a useful tool for the treatment of chronic diseases such as metabolic syndrome, insulin resistance and type 2 diabetes. The poor bioavailability of curcumin can be improved with the concomitant administration of piperine, with no severe adverse effects on glycemia reported so far in the literature. In this article, we further discuss a previously reported case of a helicopter pilot, affected by grade I obesity who, under curcumin and piperine treatment, experienced a transient loss of consciousness (TLOC), during a low-altitude flight. This episode led to a diagnosis of insulinoma, previously asymptomatic. We hypothesized that the combined effects of curcumin and piperine might have caused a severe hypoglycemic episode and subsequent TLOC. Therefore, further studies should be conducted to evaluate the safety of curcumin and piperine supplementation in subjects with impaired glucose metabolism and insulin secretion.

PURPOSE: The aim of the study was to evaluate indexes of insulin resistance and cardiometabolic risk in a large population of workers with overweight or obesity, in order to identify a possible efficient, cheap and simple strategy to apply in workers' health surveillance. METHODS: The evaluation of IR and cardiometabolic risk indexes (HOMA, QUICKI, Ty/HDLC, TyG, insuTAG, Castelli risk indexes 1 and 2, non-HDLC, TRL-C, AIP, and VAI) was performed in a population of 1195 working-age subjects with overweight or obesity (322 males, mean age 49 ± 11 years). RESULTS: The prevalence of IR and cardiometabolic risk was higher among males for all indexes. Aging, waist circumference, BMI, blood pressure, glucose, CRP, fibrinogen and uric acid were correlated more frequently with IR/cardiometabolic indexes in women, homocysteine in men. The percentage of the workers identified as insulin resistant (IR+) or at higher cardiometabolic risk greatly vary according to the different index used. CONCLUSION: With a small group of biomarkers and anthropometric measures (fasting glucose and insulin, lipid profile, BMI and waist circumference) is possible to calculate a number of IR/cardiometabolic indexes, which, likely reflecting different pathophysiological aspects also related to gender, might help in a personalized evaluation of IR and cardiometabolic risk.

AIM: Growing evidence underscores the inverse association between serum vitamin D (vit D) and chronic conditions such as metabolic syndrome, diabetes and obesity. The aim of this retrospective study was to compare weight loss and metabolic serum biomarkers in subjects on low-calorie diet receiving vit D supplementation versus those not receiving it. METHODS: The study considered 405 indoor sedentary workers with overweight/obesity and vit D insufficiency, who participated to a health fitness program between 2011-2013. Participants were recommended a moderately-low calorie diet plus vit D supplementation with 150,000 or 900,000 IU cumulative over 6 months in case of hypovitaminosis D (according to the guidelines at the enrollment), while those with optimal levels were recommended only diet. Participants were evaluated at baseline (T0), and after 6 months (T1). Anthropometric parameters, BMI, waist circumference (WC), serum 25-hydroxyvitamin D concentration ([25(OH)D]) and glycated hemoglobin (HbA1c) were assessed at T0 and T1. RESULTS: Participants fell into one of three groups: (A) not supplemented, (B) receiving 150,000 IU and (C) receiving 900,000 IU cumulative over 6 months. Overall, the supplementation was associated with increased [25(OH)D], but only the dosage of group C was associated with the achievement of optimal vit D status. A significantly greater weight decrease was observed in group B (-4.1 kg) and C (-4.5 kg) compared to untreated (-1.2 kg). WC reduction was higher in the vit D groups (group B: -3.95 cm; group C; -6.20 cm; untreated: -3.21 cm; p < 0.05). When setting the threshold for obesity at BMI > 30kg/m2, [25(OH)D] no longer correlated with body fat or weight. [25(OH)D] inversely correlated with the Homeostatic Model Assessment for Insulin Resistance and remained significant after adjustment for BMI. CONCLUSIONS: Higher [25(OH)D] levels were associated to a greater weight loss and enhanced the beneficial effects of a reduced-calorie diet in individuals with BMI > 30 kg/m2.

BACKGROUND: Alcohol and tobacco are the major risk factors for oral and pharyngeal cancer, but diet is likely to have a role, too. OBJECTIVE: The objective was to analyze the relationship between adherence to the 2015-2020 Dietary Guidelines for Americans (DGA), as measured by the Healthy Eating Index 2015 (HEI-2015), and oral and pharyngeal cancer risk. Moreover, this work aimed to quantify the number of avoidable cases under different scenarios of increased adherence to the DGA, with the use of the potential impact fraction. This estimates the proportion of cases that would occur if the distribution of the risk factor in the population followed an alternative distribution. DESIGN: A multicenter, case-control study was conducted in Italy between 1991 and 2009. Participants' usual diet for the 2 years preceding study enrolment was assessed using a food frequency questionnaire. PARTICIPANTS AND SETTING: Cases were 946 patients admitted to major hospitals with incident, histologically confirmed oral and pharyngeal cancer. Controls were 2,492 patients admitted to the same hospitals for acute non neoplastic conditions. MAIN OUTCOME MEASURES: The adherence to the DGA was assessed using the HEI-2015 score (range = 0 to 100), based on 13 components. The outcome was oral and pharyngeal cancer. STATISTICAL ANALYSES PERFORMED: Odds ratios and the corresponding 95% CIs were estimated using multiple logistic regression models adjusted for tobacco, alcohol, and other relevant covariates. The potential impact fraction was estimated under different scenarios of adherence to the DGA. RESULTS: In this Italian population the HEI-2015 score ranged from 33.4 to 97.5. A higher HEI-2015 score was associated with a lower risk of oral and pharyngeal cancer, with an odds ratio of 0.70 (95% CI 0.62 to 0.79) for a 10-point increment of the score. The estimated potential impact fraction was 64.8% under the maximum achievable reduction scenario, and it ranged from 9% to 27% following other more feasible scenarios. CONCLUSIONS: The HEI-2015 score was inversely related to oral and pharyngeal cancer risk in this Italian population. This analysis allowed for the estimation of the fraction of preventable cases, under different feasible scenarios. A share of 9% to 27% of avoidable cases of oral and pharyngeal cancer might be obtained across real-world scenarios of adherence to the DGA as measured by the HEI-2015 score.

PURPOSE: We examined the association between dietary folate intake and a score of MetS (metabolic syndrome) and its components among older adults at higher cardiometabolic risk participating in the PREDIMED-Plus trial. METHODS: A cross-sectional analysis with 6633 with overweight/obesity participants with MetS was conducted. Folate intake (per 100 mcg/day and in quintiles) was estimated using a validated food frequency questionnaire. We calculated a MetS score using the standardized values as shown in the formula: [(body mass index + waist-to-height ratio)/2] + [(systolic blood pressure + diastolic blood pressure)/2] + plasma fasting glucose-HDL cholesterol + plasma triglycerides. The MetS score as continuous variable and its seven components were the outcome variables. Multiple robust linear regression using MM-type estimator was performed to evaluate the association adjusting for potential confounders. RESULTS: We observed that an increase in energy-adjusted folate intake was associated with a reduction of MetS score (ß for 100 mcg/day = - 0.12; 95% CI: - 0.19 to - 0.05), and plasma fasting glucose (ß = - 0.03; 95% CI: - 0.05 to - 0.02) independently of the adherence to Mediterranean diet and other potential confounders. We also found a positive association with HDL-cholesterol (ß = 0.07; 95% CI: 0.04-0.10). These associations were also observed when quintiles of energy-adjusted folate intake were used instead. CONCLUSION: This study suggests that a higher folate intake may be associated with a lower MetS score in older adults, a lower plasma fasting glucose, and a greater HDL cholesterol in high-risk cardio-metabolic subjects.

Due to the lack of specific and standardized treatments for the management of fibromyalgia (FM), available evidence suggests a multidisciplinary approach, and nutrition represents an important therapeutic strategy. This work aims to update the relationship between FM and nutrition, through a review of more recent scientific evidence based on a systematic research on PubMed. Of 66 records initially identified, 26 studies were selected and included in the present work. Although there is not sufficient evidence for the efficacy of specific nutritional protocols, the examined papers indicate a potential role of selected nutrients, micronutrients and food components in managing FM symptoms. However, several concerns persist as nutritional status and/or nutritional integration can improve FM symptoms, without expecting to lead to a remission of the disease. The use of targeted nutritional supplements may be of some relevance for the management of FM, but the up to date evidence remains weak. It is advisable, thus, to perform further studies of higher quality.KEY TEACHING POINTSFibromyalgia (FM) is characterized by chronic and diffuse musculoskeletal pain, often associated with a large set of symptoms.The therapeutic approach of FM include pharmacological and non-pharmacological interventions. Among them, an important role is played by nutrition.Of 66 record screened, 12 studies were included in the present review and five of them were randomized controlled trials. Nevertheless, the overall quality of those trials was scarce.Literature concerning FM and nutritions is growing. However, little evidence suggests that nutrition and/or nutritional intervention play a significant role on FM severity.The results of this review underline the need to carry out clinical studies of higher quality and rigor, possibly RCTs, focused on the role of nutrition in the symptoms and/or severity of FM.

OBJECTIVE: We address the hypothesis that the extraordinary sandstorm occurred on 22-24 February 2020 might have a role in the different cumulated incidence of COVID-19 cases between the islands of Tenerife and Gran Canaria, since it obliged to reduce significantly air traffic and forced to suspend all major carnival street events in all most locations. METHOD: We performed a retrospective analysis of COVID-19 cases as to 1 April 2020 according to symptoms onset, weather-related data and Carnival events in Tenerife and Gran Canaria. RESULTS: The sandstorm occurred on February 22-24, 2020, forced air traffic to close, reducing the influx of tourists to the Canary Islands and suspending carnival events in most places, except in Santa Cruz de Tenerife. Cumulated incidence as to 1 April was 132.81/100,000 in Tenerife, and 56.04/100,000 in Gran Canaria. CONCLUSIONS: The suspension of Carnival events due to the sandstorm in the Canary Islands contributed to reduce differently the SARS-CoV-2 spread in Tenerife and Gran Canaria.

BACKGROUND: Nowadays the food production, supply and consumption chain represent a major cause of ecological pressure on the natural environment, and diet links worldwide human health with environmental sustainability. Food policy, dietary guidelines and food security strategies need to evolve from the limited historical approach, mainly focused on nutrients and health, to a new one considering the environmental, socio-economic and cultural impact-and thus the sustainability-of diets. OBJECTIVE: To present an updated version of the Mediterranean Diet Pyramid (MDP) to reflect multiple environmental concerns. METHODS: We performed a revision and restructuring of the MDP to incorporate more recent findings on the sustainability and environmental impact of the Mediterranean Diet pattern, as well as its associations with nutrition and health. For each level of the MDP we provided a third dimension featuring the corresponding environmental aspects related to it. CONCLUSIONS: The new environmental dimension of the MDP enhances food intake recommendations addressing both health and environmental issues. Compared to the previous 2011 version, it emphasizes more strongly a lower consumption of red meat and bovine dairy products, and a higher consumption of legumes and locally grown eco-friendly plant foods as much as possible.

BACKGROUND: Epidemiological data suggest that air pollutants are risk factors for cardiovascular disease. Recent studies have questioned the adequacy of current legal pollutant limits, because concentrations lower than those recommended still affect cardiovascular morbidity and mortality. AIM: To investigate the association between short-term exposure to air pollutants and the daily diagnosis of acute coronary syndrome (ACS) at the emergency department (ED) of S. Croce Hospital (Cuneo, Italy), between 2011 and 2015. METHODS: We evaluated the effect of particulate matter (PM2.5-10), nitrogen dioxide and ozone as primary exposure, together with temperature and relative humidity as climatological control variables, on ED admissions for ACS (response variables). We studied residents aged ≥35 years, classified into three age groups (35-64, 65-74 and ≥75 years). Environmental data were analysed according to Poisson's regression, and conventional cardiovascular risk factors (CRFs; hypertension, diabetes, coronary artery disease, smoking and dyslipidaemia) were included as control variables. RESULTS: ED admissions for ACS were 1625/391,689, with 298 in 2011 (0.183%), 305 in 2012 (0.188%), 347 in 2013 (0.214%), 341 in 2014 (0.21%) and 334 in 2015 (0.206%), with a general growth rate of 2.08% (from 2011 to 2015). The CRFs examined were confirmed to be highly associated with occurrence of ACS. Our study identified PM2.5 and temperature in all age groups to be additional risk factors, with PM2.5 exposure (P<0.01) being a particular risk for those aged ≥75 years. Dose-response models confirmed only PM2.5 as the main environmental risk factor in elderly patients (relative risk 1.06, 95% confidence interval 1.02-1.11; lag time 0-3 days). We also found a consistent relative risk for temperature in all age groups. CONCLUSION: This study confirms the importance of PM2.5 as a risk factor for ACS, mostly in elderly patients, even in a city with low annual pollution rates.

Background: the prevalence of overweight and obesity showed and increasing trend over the past few years. The burden of this epidemic represents a public health issue worldwide. Spain, and especially the Canary Islands, are not exempt. Pregnancy is a situation of weight gain, and the amount of such increase during gestation can affect the health status of both the mother and her baby. Thus, an optimal dietary style becomes of importance. Aim: given the benefits of the Mediterranean diet (MD) on various health outcomes, we aimed to study the adherence to this dietary pattern in a sample of Canarian pregnant women, and to investigate its association with their newborn's weight. Methods: adherence to MD as well as clinical history and anthropometrics were assessed in a sample of pregnant women followed at a Canarian hospital. Similarly, their newborn characteristics were studied. Results: our findings showed an overall low adherence to MD, with no association between this trend and birthweight. Conclusions: in conclusion, specific tools should be tailored to the target population to assess adherence to MD, and further efforts should be made to promote a healthy eating pattern and lifestyle among the pregnant population

BACKGROUND: This study explored the association between inactive time and measures of adiposity, clinical parameters, obesity, type 2 diabetes and metabolic syndrome components. It further examined the impact of reallocating inactive time to time in bed, light physical activity (LPA) or moderate-to-vigorous physical activity (MVPA) on cardio-metabolic risk factors, including measures of adiposity and body composition, biochemical parameters and blood pressure in older adults. METHODS: This is a cross-sectional analysis of baseline data from 2189 Caucasian men and women (age 55-75 years, BMI 27-40 Kg/m2) from the PREDIMED-Plus study (http://www.predimedplus.com/). All participants had ≥3 components of the metabolic syndrome. Inactive time, physical activity and time in bed were objectively determined using triaxial accelerometers GENEActiv during 7 days (ActivInsights Ltd., Kimbolton, United Kingdom). Multiple adjusted linear and logistic regression models were used. Isotemporal substitution regression modelling was performed to assess the relationship of replacing the amount of time spent in one activity for another, on each outcome, including measures of adiposity and body composition, biochemical parameters and blood pressure in older adults. RESULTS: Inactive time was associated with indicators of obesity and the metabolic syndrome. Reallocating 30 min per day of inactive time to 30 min per day of time in bed was associated with lower BMI, waist circumference and glycated hemoglobin (HbA1c) (all p-values < 0.05). Reallocating 30 min per day of inactive time with 30 min per day of LPA or MVPA was associated with lower BMI, waist circumference, total fat, visceral adipose tissue, HbA1c, glucose, triglycerides, and higher body muscle mass and HDL cholesterol (all p-values < 0.05). CONCLUSIONS: Inactive time was associated with a poor cardio-metabolic profile. Isotemporal substitution of inactive time with MVPA and LPA or time in bed could have beneficial impact on cardio-metabolic health. TRIAL REGISTRATION: The trial was registered at the International Standard Randomized Controlled Trial (ISRCTN: http://www.isrctn.com/ISRCTN89898870) with number 89898870 and registration date of 24 July 2014, retrospectively registered.

The Mediterranean Diet (MD) is, culturally and historically, the nutritional pattern shared by people living in the olive-tree growing areas of the Mediterranean basin. It is of great importance for its potential preventive effect against cardiovascular diseases (CVDs). The PREvención con DIeta MEDiterránea (PREDIMED) study, a Spanish multicentre randomised controlled trial (RCT), was designed to assess the long-term effects of the MD, without any energy restriction, on the incidence of CVD in individuals at high cardiovascular (CV) risk. Since its inception, it gave a great contribution to the available literature on the issue. It is well known that, in the field of the health sciences, RCTs provide the best scientific evidence. Thus, the aim of the present review is to analyse the results of the RCTs performed within the frame of the PREDIMED study. Our findings showed that MD has beneficial effects in the primary prevention of CVDs, diabetes and in the management of metabolic syndrome.

BACKGROUND: Glycated haemoglobin (HbA1c) test, introduced for diagnosing prediabetes and diabetes by the American Diabetes Association for some years, is currently under extensive discussion for contradictory data on the concordance between this test and the oral glucose tolerance test (OGTT). HYPOTHESIS: To assess concordance between HbA1c and OGTT to diagnose prediabetes and diabetes in subjects with overweight or obesity, focusing on possible gender-related differences. METHODS: A total of 949 outpatients with overweight or obesity at risk for diabetes (mean age 50 ± 15 years; 660 F) were enrolled and underwent HbA1c test and OGTT. RESULTS: In both genders, HbA1c test identified more patients with prediabetes than OGTT (42% vs 22% in males, 40% vs 18% in females, respectively): a slight concordance between HbA1c and OGTT (60% of total tests in both genders). In subjects diagnosed by OGTT, post-OGTT insulin levels and HOMA INDEX were significantly higher than those found in HbA1c(+) cases. Instead, those diagnosed with HbA1c were significantly older and showed higher uric acid than those with both tests (-). CONCLUSIONS: HbA1c test and OGTT did not reach full concordance for the diagnosis of diabetes and prediabetes in both genders. The two tests likely reflect different physiopathological aspects of dysglycaemia, suggesting that the 'diagnostic thresholds' could be reconsidered in light of the discordance observed.

Objective: Despite the increasing literature on the association of diabetes with inflammation, cardiovascular risk, and vitamin D (25(OH)D) concentrations, strong evidence on the direction of causality among these factors is still lacking. This gap could be addressed by means of artificial neural networks (ANN) analysis.Methods: Retrospective observational study was carried out by means of an innovative data mining analysis-known as auto-contractive map (AutoCM)-and semantic mapping followed by Activation and Competition System on data of workers referring to an occupational-health outpatient clinic. Parameters analyzed included weight, height, waist circumference, body mass index (BMI), percentage of fat mass, glucose, insulin, glycated hemoglobin (HbA1c), creatinine, total cholesterol, low- and high-density lipoprotein cholesterol, triglycerides, uric acid, fibrinogen, homocysteine, C-reactive protein (CRP), diastolic and systolic blood pressure, and 25(OH)D.Results: The study included 309 workers. Of these, 23.6% were overweight, 40.5% were classified into the first class of obesity, 23.3% were in the second class, and 12.6% were in the third class (BMI > 40 kg/m ). All mean biochemical values were in normal range, except for total cholesterol, low- and high-density lipoprotein cholesterol, CRP, and 25(OH)D. HbA1c was between 39 and 46 mmol/mol in 51.78%. 25(OH)D levels were sufficient in only 12.6%. Highest inverse correlation for hyperglycemia onset was with BMI and waist circumference, suggesting a protective role of 25(OH)D against their increase. AutoCM processing and the semantic map evidenced direct association of 25(OH)D with high link strength (0.99) to low CRP levels and low high-density lipoprotein cholesterol levels. Low 25(OH)D led to changes in glucose, which affected metabolic syndrome biomarkers, first of which was homeostatic model assessment index and blood glucose, but not 25(OH)D.Conclusions: The use of ANN suggests a key role of 25(OH)D respect to all considered metabolic parameters in the development of diabetes and evidences a causation between low 25(OH)D and high glucose concentrations.
