Evaluating the efficacy of current treatments for reducing postoperative ileus: a randomized clinical trial in a single center.
2014
AIM: Postoperative ileus has been considered an inevitable consequence of abdominal surgery. The aim of the study was to investigate the efficacy of same treatments in resolving postoperative ileus in various surgical approaches. METHODS: A total of 360 patients underwent abdominal surgery, and was divided into four groups: videolaparoscopic cholecystectomy, laparotomic colo-rectal surgery, laparotomic Hartmann procedure, laparotomic gastric surgery. In each group, patients received different postoperative treatments: chewing gum, olive oil, both, and water. Each group was compared with a control group. RESULTS: In patients who underwent videolaparoscopic cholecystectomy, median postoperati…
Reduction in the Incidence of Type 2 Diabetes With the Mediterranean Diet
2010
OBJECTIVE To test the effects of two Mediterranean diet (MedDiet) interventions versus a low-fat diet on incidence of diabetes. RESEARCH DESIGN AND METHODS This was a three-arm randomized trial in 418 nondiabetic subjects aged 55–80 years recruited in one center (PREDIMED-Reus, northeastern Spain) of the Prevención con Dieta Mediterránea [PREDIMED] study, a large nutrition intervention trial for primary cardiovascular prevention in individuals at high cardiovascular risk. Participants were randomly assigned to education on a low-fat diet (control group) or to one of two MedDiets, supplemented with either free virgin olive oil (1 liter/week) or nuts (30 g/day). Diets were ad libitum, and no…
Inverse association between habitual polyphenol intake and incidence of cardiovascular events in the PREDIMED study
2014
Background and aims: Epidemiologic and biological evidence supports an inverse association between polyphenol consumption and the risk of cardiovascular disease (CVD). However, no previous studies have prospectively evaluated the relationship between polyphenol intake and the incidence of CVD in such a comprehensive way. The aim was to evaluate the association between intakes of total polyphenol and polyphenol subgroups, and the risk of major cardiovascular events (myocardial infarction, stroke or death from cardiovascular causes) in the PREDIMED study. Methods and results: The present work is an observational study within the PREDIMED trial. Over an average of 4.3 years of follow-up, there…
Reduction in systemic and VLDL triacylglycerol concentration after a 3-month Mediterranean-style diet in high-cardiovascular-risk subjects.
2010
The first results of the PREDIMED (PREvencion con Dieta MEDiterranea) randomized trial, after 3-month intervention, showed that the Mediterranean Diet (MD), supplemented with either virgin olive oil (VOO) or nuts, reduced systolic blood pressure, serum cholesterol and triacylglycerol (TG) concentrations and increased high-density lipoprotein (HDL)-cholesterol when compared to a control (low-fat diet) group. Serum TG levels are an independent risk factor for coronary heart disease and are strongly determined by very low-density lipoprotein (VLDL) composition, which can be specifically modified by dietary lipid source. Within the context of the PREDIMED study, we assessed the VLDL composition…
Dietary intake of vitamin K is inversely associated with mortality risk
2014
Vitamin K has been related to cardiovascular disease and cancer risk. However, data on total mortality are scarce. The aimof the present study was to assess the association between the dietary intake of different types of vitamin K and mortality in a Mediterranean population at high cardiovascular disease risk. A prospective cohort analysis was conducted in 7216 participants from the PREDIMED (Prevención con Dieta Mediterránea) study (median follow-up of 4.8 y). Energy and nutrient intakes were evaluated using a validated 137-item food frequency questionnaire. Dietary vitamin K intake was calculated annually using the USDA food composition database and other published sources. Deaths were a…
Ultrasonic cavitation induced water in vegetable oil emulsion droplets--a simple and easy technique to synthesize manganese zinc ferrite nanocrystals…
2012
In the present investigation, synthesis of manganese zinc ferrite (Mn(0.5)Zn(0.5)Fe(2)O(4)) nanoparticles with narrow size distribution have been prepared using ultrasound assisted emulsion (consisting of rapeseed oil as an oil phase and aqueous solution of Mn(2+), Zn(2+) and Fe(2+) acetates) and evaporation processes. The as-prepared ferrite was nanocrystalline. In order to remove the small amount of oil present on the surface of the ferrite, it was subjected to heat treatment at 300 °C for 3h. Both the as-prepared and heat treated ferrites have been characterized by X-ray diffraction (XRD), infrared spectroscopy (IR), TGA/DTA, transmission electron microscopy (TEM) and energy dispersion X…
Essential oils as natural additives to prevent oxidation reactions in meat and meat products: A review
2018
Oxidation reactions during manufacturing, distribution, and storage of meat and meat products result in undesirable physicochemical changes and aromas, which leads to detrimental effects on the product quality. This could be translated into the consumer dissatisfaction and economic loss. One of the most common practices to overcome this issue is the incorporation of synthetic antioxidants. However, the increasing health-consciousness of consumers and their preference for natural additives leads to the search of natural alternatives to synthetic antioxidants. A number of essential oils have strong antioxidant properties and are explored as potential alternatives to chemical antioxidants in t…
New insights into Early Celtic consumption practices: Organic residue analyses of local and imported pottery from Vix-Mont Lassois
2019
The rich Mediterranean imports found in Early Celtic princely sites (7th-5th cent. BC) in Southwestern Germany, Switzerland and Eastern France have long been the focus of archaeological and public interest. Consumption practices, particularly in the context of feasting, played a major role in Early Celtic life and imported ceramic vessels have consequently been interpreted as an attempt by the elite to imitate Mediterranean wine feasting. Here we present the first scientific study carried out to elucidate the use of Mediterranean imports in Early Celtic Central Europe and their local ceramic counterparts through organic residue analyses of 99 vessels from Vix-Mont Lassois, a key Early Celti…
Mediterranean diet and longevity: an example of nutraceuticals?
2013
The Mediterranean diet (Mediet) is an eating pattern characterizing a lifestyle and culture that has been reported to contribute to better health and quality of life. The Mediet reflects food patterns typical of Mediterranean regions, where olive oil plays an essential role in the food pyramid. Olive oil is located in the middle and it is considered the principal source of dietary fat because of its high nutritional quality (particularly extra virgin olive oil). Several studies have shown the effect of the Mediet on healthy status by lowering the rates of coronary heart disease, certain cancers, and some other age-related chronic diseases. Although the scientific literature regarding diet a…
Comparison of the Fungistatic Activity of Selected Essential Oils Relative to
2018
The aim of the study was to determine the chemical composition of lemon, rosewood, geranium and rosemary oils, and compare their effect on the sensitivity of Fusarium graminearum ZALF 24 and Fusarium graminearum ZALF 339 isolated from infected cereals. The tested oils were added to Potato Dextrose Agar (PDA) medium at concentrations of 0.125%, 0.25%, 0.5%, 1.0% and 2.0%. The activity of the oils on inhibition of the linear growth of mycelium was evaluated by measuring the growth of fungal colonies (growth index), while the fungistatic activity was evaluated on the basis of the percentage growth inhibition of a fungal colony and calculated according to Abbott’s formula. The sensitivity of th…
