Chronic Hyperinsulinemia Does Not Increase the Production Rate of High-Density Lipoprotein Apolipoprotein AI
2013
Objective— In vitro studies showed that insulin stimulates the production of apolipoprotein AI (apoAI). Thus, we hypothesized that chronic hyperinsulinemia could contribute to the increase in the production of high-density lipoprotein apoAI that is observed in metabolic syndrome. Approach and Results— We performed an in vivo kinetic study with stable isotope in 7 patients with insulinoma who showed hyperinsulinemia but no insulin resistance, 8 patients with insulin resistance, and 16 controls. Insulinemia was 3.1× ( P <0.01) higher in patients with insulinoma or insulin resistance than in controls in the fasting state and, respectively, 3.5× and 2.6× ( P <0.05) higher in the fed stat…
The latent structure of the functional dyspepsia symptom complex: A taxometric analysis
2016
OBJECTIVES: Rome III introduced a subdivision of functional dyspepsia (FD) into postprandial distress syndrome and epigastric pain syndrome, characterized by early satiation/postprandial fullness, and epigastric pain/burning, respectively. However, evidence on their degree of overlap is mixed. We aimed to investigate the latent structure of FD to test whether distinguishable symptom-based subgroups exist. METHODS: Consecutive tertiary care Rome II FD patients completed the dyspepsia symptom severity scale. Confirmatory factor analysis (CFA) was used to compare the fit of a single factor model, a correlated three-factor model based on Rome III subgroups and a bifactor model consisting of a g…
Tavallisen ihmisen uskottavuus mainoksen suosittelijana ja uskottavuuden vaikutus asenteeseen mainosta ja brandia kohtaan
2012
Tutkimuksen tavoitteena oli tutkia tavallisten ihmisten käyttöä mainoksen suosittelijoina, tavallisen ihmisen uskottavuutta suosittelijana ja uskottavuuden vaikutusta asenteeseen mainosta ja brandia kohtaan. Aikaisempaa tutkimusta aiheesta löytyi melko vähän, joten teoriapohjana käytettiin source credibility –teoriaa, jota on käytetty julkisuuden henkilöitä mainosten suosittelijoina tutkittaessa. Muiden aikaisempien tutkimustulosten perusteella mallia muokattiin niin, että tavallisen ihmisen uskottavuus suosittelijana oletettiin muodostuvan luotettavuudesta, asiantuntijuudesta ja samankaltaisuudesta. Tutkimukseen valittiin kolme erilaista, ulkonäköön liittyvää mainosta, joissa suosittelijoi…
Diabetes mellitus secondary to Cushing's disease
2018
Associated with important comorbidities that significantly reduce patients’ overall wellbeing and life expectancy, Cushing’s disease (CD) is the most common cause of endogenous hypercortisolism. Glucocorticoid excess can lead to diabetes, and although its prevalence is probably underestimated, up to 50% of patients with CD have varying degrees of altered glucose metabolism. Fasting glycemia may nevertheless be normal in some patients in whom glucocorticoid excess leads primarily to higher postprandial glucose levels. An oral glucose tolerance test should thus be performed in all CD patients to identify glucose metabolism abnormalities. Since diabetes mellitus (DM) is a consequence of cortis…
Lipemia postprandial y regulación génica en la obesidad mórbida
2018
La obesidad es una enfermedad multifactorial que ocasiona una alteración metabólica crónica. Los pacientes con obesidad mórbida presentan un riesgo elevado de desarrollar enfermedades cardiovasculares, así como de presentar resistencia a la insulina implicada en la patogenia del síndrome metabólico y el desarrollo de diabetes mellitus tipo 2. La incapacidad actual para prevenir o revertir el desarrollo de la obesidad nos obliga a buscar estrategias alternativas para identificar a aquellos sujetos con un mayor riesgo de desarrollar complicaciones cardiometabólicas. La heterogeneidad existente parece no poder explicarse por los factores de riesgo “clásicos” conocidos. La lipemia postprandial …
Off-line control of the postprandial glycemia in type 1 diabetes patients by a fuzzy logic decision support
2012
The target of this paper is to describe the use of fuzzy techniques in the development of a decision support system that allows the optimization of postprandial glycemia in type 1 diabetes patients taking into account the kind of meal taken by patients, the preprandial glycemia and the insulin resistance (the response of the body to insulin dose injection therapy). The decision support system can, in many cases, provide patients with the correct number of rapid insulin units that must be assumed to assure an optimal glycemic profile, keeping the blood glucose level close to the homeostatic condition, several hours after the meal.
Sensory-specific satiety for a food is unaffected by the ad libitum intake of other foods during a meal. Is SSS subject to dishabituation?
2012
Sensory-specific satiety (SSS) is defined as a decrease in the pleasantness of a specific food that has just been eaten to satiation, while other non-eaten foods remain pleasant. The objectives of this study were the following: (1) to investigate whether SSS for a food is affected by the ad libitum intake of other foods presented sequentially during a meal, (2) to compare the development of SSS when foods are presented simultaneously or sequentially during a meal, and (3) to examine whether SSS is modified when foods are presented in an unusual order within a meal. Twelve participants participated in three tasting sessions. In session A, SSS for protein-, fat- and carbohydrate-rich sandwich…
Efecto de la sobrecarga oral con grasa insaturada sobre los marcadores de estrés oxidativo e inflamación : estudios de lipemia postprandial en sujeto…
2011
Objetivos: Estudiar el efecto en los marcadores de estrés oxidativo (EO) en linfomonocitos circulantes y de inflamación sistémica relacionada con la arteriosclerosis tras un sobrecarga oral con grasa (SOG) monoinsaturada en sujetos con hipercolesterolemia familiar (HF) heterocigota y comparar esta respuesta con la obtenida en sujetos normolipémicos normoglucémicos. Sujetos y métodos: Se estudiaron 14 pacientes FH y 22 voluntarios sanos como grupo control. En ambos, se determinaron el cociente glutation oxidado/reducido y niveles de malondialdehido en linfomonocitos y niveles plasmáticos de IL-6, IL8, TNFα, eotaxina, MCP-1 y MIP-1α en ayunas y a las 2, 4, 6 y 8 horas tras una SOG. Asimismo, …
Low-density lipoproteins generated during an oral fat load in mild hypertriglyceridemic and healthy subjects are smaller, denser, and have an increas…
2005
Triglyceride-rich lipoproteins generated during the postprandial phase are atherogenic. Large very low-density lipoproteins (LDLs) or chylomicrons (CMs) are not as atherogenic as their remnants (Rem). Small and dense LDLs are associated with cardiovascular disease. Low-density lipoprotein size is partly under genetic control and is considered as a relatively stable LDL feature. In this article, we present data on retinyl palmitate kinetics correlated with the modification of LDL features in terms of size, density, and in vitro receptor binding affinity after an oral fat load. Six nondiabetic, hypertriglyceridemic (HTG) patients and 6 healthy controls were examined. Low-density lipoprotein s…
Emerging approaches for the treatment of hypertriglyceridemia.
2013
Hypertriglyceridemia is frequent in diabetic and obese subjects, who are at increased risk for cardiovascular diseases (CVD). Increased triglycerides (TG) are a hallmark of atherogenic dyslipidemia, representing a marker of atherogenic small dense low-density lipoproteins (sdlDL). Importantly, non-fasting/postprandial TG measurements tend to be emphasized in clinical practice for the prediction of CVD, and TG-lowering agents (primarily fibrates) have a beneficial effect on atherogenic dyslipidemia, reducing TG-rich particles and ultimately lowering the production of sdlDL. The combination of omega-3 fatty acids and statins is also recommended, and widely used in clinical practice for subjec…
