Relationship Between Body Mass Index, ApoE4 Status, and PET-Based Amyloid and Neurodegeneration Markers in Amyloid-Positive Subjects with Normal Cogn…
2018
Body weight loss in late-life is known to occur at a very early stage of Alzheimer's disease (AD). Apolipoprotein E4 (ApoE4) represents a major genetic risk factor for AD and is linked to an increased cortical amyloid-β (Aβ) accumulation. Since the relationship between body weight, ApoE4, and AD pathology is poorly investigated, we aimed to evaluate whether ApoE4 allelic status modifies the association of body mass index (BMI) with markers of AD pathology. A total of 368 Aβ-positive cognitively healthy or mild cognitive impaired subjects had undergone [18F]-AV45-PET, [18F]-FDG-PET, and T1w-MRI examinations. Composite cortical [18F]-AV45 uptake and [18F]-FDG uptake in posterior cingulate cor…
Real-World Hypertension Prevalence, Awareness, Treatment, and Control in Adult Diabetic Individuals: An Italian Nationwide Epidemiological Survey
2021
Introduction: Hypertesion is the leading cause of morbidity and mortality, worldwide, and its prevalence has been increasing in several countries, including Italy. Aims: To assess hypertension prevalence, awareness, treatment, and control in a real-world sample of adults with self-reported diabetes compared with nondiabetic individuals. Methods: Following the 2018 World Hypertension Day, a nationwide, cross-sectional epidemiological survey on cardiovascular risk factors (“Abbasso la Pressione!”) in 3956 Italian pharmacies enrolled 47217 self-presenting volunteers (≥ 18 years). Participants underwent standardized blood pressure (BP) measurements and answered a questionnaire on cardiovascular…
Liver and Cardiovascular Damage in Patients With Lean Nonalcoholic Fatty Liver Disease, and Association With Visceral Obesity.
2017
Background & Aims Lean nonalcoholic fatty liver disease (NAFLD) is defined as NAFLD that develops in patients with a body mass index (BMI) less than 25 kg/m2. We investigated the differences between lean NAFLD and NAFLD in overweight and obese persons, factors associated with the severity of liver and cardiovascular disease, and the effects of visceral obesity. Methods We performed a retrospective cohort study of 669 consecutive patients with biopsy-proven NAFLD seen at 3 liver centers in Italy. We collected anthropometric, clinical, and biochemical data, as well as information on carotid atherosclerosis (artery intima-media thickness and plaque), liver histology (nonalcoholic steatohepatit…
The effects of acceptance and commitment therapy on eating behavior and diet delivered through face-to-face contact and a mobile app: a randomized co…
2018
Background Internal motivation and good psychological capabilities are important factors in successful eating-related behavior change. Thus, we investigated whether general acceptance and commitment therapy (ACT) affects reported eating behavior and diet quality and whether baseline perceived stress moderates the intervention effects. Methods Secondary analysis of unblinded randomized controlled trial in three Finnish cities. Working-aged adults with psychological distress and overweight or obesity in three parallel groups: (1) ACT-based Face-to-face (n = 70; six group sessions led by a psychologist), (2) ACT-based Mobile (n = 78; one group session and mobile app), and (3) Control (n = 71; …
Oxidative and endoplasmic reticulum stress is impaired in leukocytes from metabolically unhealthy vs healthy obese individuals.
2017
BACKGROUND: Oxidative stress and inflammation are related to obesity, but the influence of metabolic disturbances on these parameters and their relationship with endoplasmic reticulum (ER) stress is unknown. Therefore, this study was performed to evaluate whether metabolic profile influences ER and oxidative stress in an obese population with/without comorbidities. SUBJECTS AND METHODS: A total of 113 obese patients were enrolled in the study; 29 were metabolically healthy (MHO), 53 were metabolically abnormal (MAO) and 31 had type 2 diabetes (MADO). We assessed metabolic parameters, proinflammatory cytokines (TNF alpha and IL-6), mitochondrial and total reactive oxygen species (ROS) produc…
Providing choice and/or variety during a meal: Impact on vegetable liking and intake
2016
Food choice is defined as providing the opportunity for an individual to select the food he or she wants to consume while food variety is defined as providing an individual with foods that differ on at least one sensory characteristic. Literature shows that providing food choice or providing food variety may increase meal enjoyment and food intake. However, these two factors have been mainly investigated separately, while they may actually co-occur in real-life settings. In fact, in many out-of-home catering situations, individuals have the possibility to choose as many dishes as they desire from among different proposals for their meal. The aim of the present study was to assess the impact…
High dietary protein intake is associated with an increased body weight and total death risk.
2015
Summary Background & aims High dietary protein diets are widely used to manage overweight and obesity. However, there is a lack of consensus about their long-term efficacy and safety. Therefore, the aim of this study was to assess the effect of long-term high-protein consumption on body weight changes and death outcomes in subjects at high cardiovascular risk. Methods A secondary analysis of the PREDIMED trial was conducted. Dietary protein was assessed using a food-frequency questionnaire during the follow-up. Cox proportional hazard models were used to estimate the multivariate-adjusted hazard ratio (HR) and 95% confidence intervals (95%CI) for protein intake in relation to the risk of bo…
Disease severity in patients with visceral leishmaniasis is not altered by co-infection with intestinal parasites
2017
Visceral leishmaniasis (VL) is a neglected tropical disease that affects the poorest communities and can cause substantial morbidity and mortality. Visceral leishmaniasis is characterized by the presence of Leishmania parasites in the spleen, liver and bone marrow, hepatosplenomegaly, pancytopenia, prolonged fever, systemic inflammation and low body mass index (BMI). The factors impacting on the severity of VL are poorly characterized. Here we performed a cross-sectional study to assess whether co-infection of VL patients with intestinal parasites influences disease severity, assessed with clinical and haematological data, inflammation, cytokine profiles and BMI. Data from VL patients was s…
Effectiveness of the physical activity intervention program in the PREDIMED-Plus study: a randomized controlled trial
2018
[Background] The development and implementation of effective physical activity (PA) intervention programs is challenging, particularly in older adults. After the first year of the intervention program used in the ongoing PREvención con DIeta MEDiterránea (PREDIMED)-Plus trial, we assessed the initial effectiveness of the PA component.
Adherence to the Mediterranean diet is associated with better quality of life: data from the Osteoarthritis Initiative
2016
BACKGROUND The Mediterranean diet has positively influenced various medical conditions, but only a paucity of studies has considered the relation between the Mediterranean diet and quality of life (QOL) among people living in North America. OBJECTIVE We investigated whether a higher adherence to the Mediterranean diet (aMED) was associated with better QOL and decreased pain, stiffness, disability, and depression in a large cohort of North Americans from the Osteoarthritis Initiative. DESIGN aMED was evaluated through a validated Mediterranean diet score categorized into quintiles. Outcomes of interest were QOL [assessed with the 12-Item Short-Form Health Outcome Survey (SF-12)]; disability,…
