Non-celiac gluten sensitivity: literature review.

2014

A significant percentage of the general population report problems caused by wheat and/or gluten ingestion, even though they do not have celiac disease (CD) or wheat allergy (WA), because they test negative both for CD-specific serology and histopathology and for immunoglobulin E (IgE)-mediated assays. Most patients report both gastrointestinal and nongastrointestinal symptoms, and all report improvement of symptoms on a gluten-free diet. This clinical condition has been named non-celiac gluten sensitivity (NCGS).We attempt to define the current pathogenic, clinical, and diagnostic criteria of this "new" disease, to provide a practical view that might be useful to evaluate, diagnose, and ma…

Matrix metalloproteinases in metabolic syndrome.

2011

Metabolic syndrome is commonly accompanied by an elevated cardiovascular risk with high morbidity and mortality. The alterations of the arterial vasculature begin with endothelial dysfunction and lead to micro- and macrovascular complications. The remodeling of the endothelial basal membrane, that promotes erosion and thrombosis, has a multifactorial pathogenesis that includes leukocyte activation, increased oxidative stress and also an altered matrix metalloproteinases (MMPs) expression. MMPs are endopeptidases which degrade extracellular matrix proteins, such as collagen, gelatins, fibronectin and laminin. They can be secreted by several cells within the vascular wall, but macrophages are…

Protein oxidation in metabolic syndrome

2013

Purpose: Oxidative stress plays a pivotal role in the pathogenesis of the metabolic syndrome and in the progression of its complications. Carbonylated proteins are a stable marker of severe oxidative stress because damage to the protein structure is irreversible and may cause an inhibition of their enzymatic activity or an increased susceptibility to proteolysis. There are few data regarding protein oxidation in metabolic syndrome, although elevated levels of carbonyl groups are often detected in subjects with obesity, diabetes mellitus, hypertension or dyslipidemia, well-known components of the metaboic syndrome. In particular, obesity, insulin resistance and diabetes mellitus are frequent…

Lipid levels in polycystic ovary syndrome: systematic review and meta-analysis.

2011

Objective To quantify the magnitude and pattern of low-density lipoprotein (LDL) cholesterol and nonhigh-density lipoprotein (HDL) cholesterol levels in women with polycystic ovary syndrome (PCOS) versus control women. Design Systematic review and meta-analysis of lipid levels in published cross-sectional studies worldwide where PCOS women and controls were examined and sampled. Main Outcome Measure(s) Differences in plasma lipids (including triglycerides, HDL-cholesterol, LDL-cholesterol, and nonHDL-cholesterol) in PCOS versus control subjects were calculated. Comparisons were made with and without body mass index (BMI) matching. Result(s) Triglyceride levels were 26 mg/dL (95% confidence …

Tratamiento integral de la dislipidemia diabética: beneficios y nuevas alternativas terapéuticas

2010

Diabetic dyslipidemia, characterized by the lipid triad (elevated plasma triglycerides, low HDL cholesterol and predominance of small, dense LDL particles), is a significant contributor to the elevated cardiovascular risk of type 2 diabetic patients. Statin monotherapy has shown, in different prospective trials, significant reductions in cardiovascular events and mortality. However, the residual risk in these subjects remains elevated, probably due to the incomplete control of diabetic dyslipidemia. In this review we discuss the global therapeutic approach, underlying the need of combining statins with agents that more effective in reducing triglycerides and elevating HDL cholesterol, even …

Should we measure routinely the LDL peak particle size?

2004

Low density lipoproteins (LDL) do not show in humans a normal distribution and comprise two different main fractions: large, buoyant (phenotype pattern A) and small, dense (phenotype pattern B) particles, that differ not only in size and density but also in physicochemical composition, metabolic behaviour and atherogenicity. The prevalence of small, dense LDL changes with age (30-35% in adult men, 5-10% in men <20 years and in pre-menopausal women, 15-25% in postmenopausal women) and is genetically influenced, with a heritability ranging from 35% to 45%. Small, dense LDL correlate negatively with plasma HDL levels and positively with plasma triglyceride levels and are associated with the me…

PO-0322 The Effective Dose Of Sodium Bicarbonate In Severe Acute Dehydration And Metabolic Acidosis Due To Acute Diarrhoea In Children

2014

Background Still exist controversies about sodium bicarbonate (SB) effectiveness in metabolic acidosis (MA). The SB dose finally remain at discretion of physician. Aims Proving SB efficiency in severe acute dehydration (SAD) with MA secondary to acute diarrhoea (AD) in children. Methods Retrospective study conducted between May–September 2013, in 0–5 years old patients hospitalised for AD with SAD and MA. We chose the propitious age group and season for acute gastrointestinal pathology. We considered SAD loss >10% of body weight and severe MA pH Results In A Group, at admission, 57,14% presented pH 15; at 4 H, all presented alkalosis. In B Group, at admission, 50% presented severe MA; at 1 …

Lift weights to fight overweight

2014

Although resistance training (RT) has long been accepted as a means for developing and maintaining muscular strength, endurance, power and muscle mass, its beneficial relationship with health factors and chronic disease has only recently been recognized in the scientific literature. Prior to 1990, resistance training was not a part of the recommended guidelines for exercise training and rehabilitation for either the American Heart Association or the American College of Sports Medicine (ACSM). In 1990, the ACSM recognized resistance training as a significant component of a comprehensive fitness programme for healthy adults of all ages, a position subsequently confirmed few years after. At pr…

Reliability and concurrent validity of the International Physical Activity Questionnaire short form among pregnant women

2017

Abstract Sanda B, Vistad I, Haakstad LAH, Berntsen S, Sagedal LR, Lohne-Seiler H, Torstveit MK. Reliability and concurrent validity of the International Physical Activity Questionnaire short form among pregnant women. Background The International Physical Activity Questionnaire short-form (IPAQ-SF) is frequently used to assess physical activity (PA) level in the general adult population including pregnant women. However, the reliability and validity of the questionnaire in pregnancy is unknown. Therefore, the aims of the present study were to investigate test-retest reliability and concurrent validity of IPAQ-SF among pregnant women, and whether PA is reported differently among those who fu…
