Impact of lifestyle on metabolic syndrome in apparently healthy people.

2014

Parallel to the increase in obesity, the prevalence of metabolic syndrome (MetS) is continually increasing, with increased risk of diabetes and cardiovascular atherosclerosis diseases. Despite the importance of this public health problem, the relative impact of diet and physical activity on MetS prevalence has yet to be established. We investigated the association between lifestyle, in terms of both habitual dietary pattern and physical activity, and MetS in a cohort of adults without known diabetes and atherosclerotic cardiovascular disease. Four hundred seventy-seven randomly selected adult participants were cross-sectionally investigated. Each participant answered a food frequency questi…

Obesity and Circulating Levels of Vitamin D before and after Weight Loss Induced by a Very Low-Calorie Ketogenic Diet

2021

Background: Vitamin D plays a pivotal role in calcium and phosphorus metabolism, also influencing bone tissue. Several studies have reported that vitamin D blood levels were significantly lower in people with obesity, probably due to its uptake by the adipose tissue. Clinical studies that investigated the changes of circulating levels of vitamin D following weight loss reported controversial data. A very low-calorie ketogenic diet is acknowledged as a reliable treatment to achieve a rapid weight loss. Therefore, we investigated the effect of weight loss, consequent to a very low-calorie ketogenic diet, on vitamin D blood concentrations. Methods: A cohort of 31 people with obesity underwent …

Intra-renal hemodynamics and carotid intima-media thickness in the metabolic syndrome.

2009

Aims: Metabolic syndrome (MetS) is associated with increased cardiovascular risk. We hypothesize that early vascular changes are already present at the time of diagnosis of MetS. The relationship of different measures of early vascular impairment with body fat distribution and the natural progression of MetS was examined in newly diagnosed subjects non-pharmacologically treated. Methods: 246 consecutively enrolled subjects were categorized according to the presence of MetS and type 2 diabetes (T2D). Intra-renal Doppler flow was used to ascertain resistive (RI) and pulsatility (PI) indices as markers of vascular resistance. Carotid intima-media thick- ness (IMT), cutis-rectis (CR) and rectis…

Time-Restricted Feeding and Metabolic Outcomes in a Cohort of Italian Adults.

2021

Background: research exploring the effects of food timing and frequency on health and disease is currently ongoing. While there is an increasing body of scientific literature showing the potential health benefits of intermittent fasting (IF) in laboratory settings and in animals, studies regarding IF on humans are limited. Therefore, the objective of this research was to evaluate the relationship between the feeding/fasting time window and metabolic outcomes among adult individuals. Methods: dietary and demographic data of 1936 adult subjects living in the south of Italy were examined. Food frequency questionnaires (FFQ) were administered to determine the period of time between the first an…

Interplay between non-alcoholic fatty liver disease and cardiovascular risk in an asymptomatic general population

2020

BACKGROUND AND AIMS Non-alcoholic fatty liver (NAFLD) is a major cause of liver disease worldwide leading also to a higher risk of cardiovascular events. We aimed to evaluate the impact of fatty liver and fibrosis on cardiovascular risk in a general population. METHODS Five hundred and forty-two subjects included in the community-based ABCD (Alimentazione, Benessere Cardiovascolare e Diabete) study were recruited. Steatosis (controlled attenuation parameter > 288 dB/m) and severe fibrosis (low risk, liver stiffness measurement [LSM] < 7.9 KPa with M probe and < 5.7 KPa with XL probe; intermediate risk, LSM 7.9-9.5 KPa with M probe and 5.7-9.2 KPa with XL probe; high risk, LSM ≥ 9.6 KPa with…

Dietary Fats and Cardio-Metabolic Outcomes in a Cohort of Italian Adults

2022

Background: Dietary fats, and especially saturated fatty acid (SFA), have been blamed for being the culprit in the dramatic increase in obesity and its associated diseases. However multiple systematic reviews and recent meta-analyses do not support the association between SFA and cardiovascular diseases. Thus, the objective of this study was to test whether specific types and subtypes of dietary fats are associated with metabolic outcomes in a cohort of Italian adults. Methods: Nutritional and demographic data of 1936 adults living in the south of Italy were examined. Food frequency questionnaires (FFQs) were administered to assess the intake of total dietary fat and each specific class of …

Red Orange: Experimental Models and Epidemiological Evidence of Its Benefits on Human Health

2013

In recent years, there has been increasing public interest in plant antioxidants, thanks to the potential anticarcinogenic and cardioprotective actions mediated by their biochemical properties. The red (or blood) orange (Citrus sinensis(L.) Osbeck) is a pigmented sweet orange variety typical of eastern Sicily (southern Italy), California, and Spain. In this paper, we discuss the main health-related properties of the red orange that include anticancer, anti-inflammatory, and cardiovascular protection activities. Moreover, the effects on health of its main constituents (namely, flavonoids, carotenoids, ascorbic acid, hydroxycinnamic acids, and anthocyanins) are described. The red orange juice…

Role of Dietary Carotenoids in Frailty Syndrome: A Systematic Review

2022

Unbalanced diets and altered micronutrient intake are prevalent in the aging adult population. We conducted a systematic review to appraise the evidence regarding the association between single (α-carotene, β-carotene, lutein, lycopene, β-cryptoxanthin) or total carotenoids and frailty syndrome in the adult population. The literature was screened from study inception to December 2021, using six different electronic databases. After establishing inclusion criteria, two independent researchers assessed the eligibility of 180 retrieved articles. Only 11 fit the eligibility requirements, reporting five carotenoid entries. No exclusion criteria were applied to outcomes, assessment tools, i.e., f…

TECNICHE OTTICHE PER IL MONITORAGGIO DEI CORSI D’ACQUA: UNA PROCEDURA AUTOMATICA PER L’INDIVIDUAZIONE DELLA MIGLORE SEQUENZA VIDEO DA PROCESSARE CON …

Misurare con accuratezza le portate di un corso d’acqua è uno dei principali obiettivi dell’idrometria tecnica (Eltner et al., 2020) e rappresenta da decenni una vera e propria sfida per la comunità scientifica. Le osservazioni di deflusso nei corsi d’acqua sono di fondamentale importanza per qualsiasi applicazione idrologica e idraulica (Pizarro et al., 2020) e consentono di comprendere al meglio le dinamiche di processi complessi, come ad esempio le piene lampo (Perks et al., 2016). La portata è una grandezza fisica la cui stima è caratterizzata da considerevole incertezza. Gli approcci tradizionali prevedono una stima indiretta della grandezza, attraverso un metodo velocità-area, che con…
