Abstract

Background and Aims: The aim of this study was to document the eating habits of normal weight and obese patients in order to implement a new and healthier lifestyle. Material and Methods: We evaluated the intake of energy and that of vitamins and minerals in a sample of 199 normal weight and obese subjects. We also performed anthropometric's measurements, paraclinic’s and laboratory’s tests. Results: The mean intake of vitamins and minerals is significantly different for B1 and B3 vitamins and for iron, phosphorus, copper and selenium. Vitamins like B1, B2, B3, B6, B12, C and A vitamin and minerals like, zinc, manganese, phosphorus and selenium are over consumed in both groups. Regarding the sodium’s intake, only 37.04% of normal weight patients fulfill the recommendations of less than 2 g/day. The prevalence of a high fat diet is about 59.29% in normal weight people and 60.69% among obese ones. Only 25% of normal weight patients had normal abdominal circumference and 58.47% of obese subjects had normal HDL-cholesterol levels. Conclusions: Regardless the body mass index (BMI) status, neither normal weight subjects nor the obese ones' had an adequate micronutrient intake. Also, there is a high prevalence of high sodium’s intake and a high fat diet among the normal weight patients.

Abstract

Introduction. Mild cognitive impairment (MCI) is the prodromal stage of Alzheimer’s disease (AD), so identification of the related risk factors can be helpful. There are controversial data regarding the serum oxidant/antioxidant status, trace elements and homocysteine (Hcy) as effective parameters in this disease, therefore the status of these factors was determined in this study.

Methods. One hundred-twenty elderly persons with cognitive impairment and 120 elderly healthy persons who were differentiated using Mini-mental state examination (MMSE) participated in this study. The patients were divided into mild and moderate-to-severe cognitive impairment group. Serum antioxidant/oxidant, copper (Cu), manganese (Mn), zinc (Zn) and Hcy concentrations were measured using routine methods.

Results. Oxidant and antioxidant levels increased and decreased based on the severity of the disease and were higher and lower in patients than in control group, respectively (p<0.001). With adjusting for age, gender and education, significant difference in Hcy levels was not observed. There was no significant difference in trace elements levels among groups.

Conclusions. Results confirmed the association between oxidative damage with increasing the severity of cognitive impairment. These factors may be involved in the etiology of cognitive impairment and AD. Identification of such biomarkers is important to select appropriate treatment goals before the onset of irreversible clinical signs.

antioxidant enzymes such as superoxide dismutase (SOD), glutathione peroxidase (GPX) and catalase (CAT). Manganese superoxide dismutase (SOD2) is the major antioxidant in mitochondria, catalysing the dismutation of superoxide anion to H 2 O 2 , which is then reduced to water by CAT or GPX. 20 , 21 Many studies have investigated genetic variability in genes coding for antioxidant enzymes and their relationship to cancer risk, however the results were inconclusive 22 and the data on thyroid cancer risk are lacking. 23 The most common polymorphism in the gene coding for

, complex defence mechanisms including many enzymes, proteins and antioxidants are involved. Antioxidant enzymes such as manganese superoxide dismutase (Mn-SOD), glutathione peroxidase (GPX) and catalase (CAT) directly eliminate ROS, while glutathione-S-transferases (GSTs) detoxify cytotoxic secondary metabolites. Numerous functional polymorphisms in the genes coding for antioxidant enzymes have been described that may also modify their ROS detoxification capacity. 17 Oxidative stress and ROS have been associated with several cancers and also many complex diseases like
