Validity and reliability of simple surrogate indexes to evaluate beta-cell function and insulin sensitivity

Rev. méd. Chile; 150 (11), 2022
BACKGROUND: Simple surrogate indexes (SSI) to assess beta-cell function, insulin sensitivity (IS) and insulin resistance (IR) are an easy and economic tool used in clinical practice to identify glucose metabolism disturbances. AIM: To evaluate the validity and reliability of SSI that estimate beta-cell f...

Perfil dos pacientes com hiperferritinemia em acompanhamento ambulatorial em um serviço no sul do Brasil

O achado de hiperferritinemia é comum na prática clínica. Além de representar os estoques de ferro no organismo, a ferritina se mostra como proteína de fase inflamatória, podendo elevar-se em comorbidades inflamatórias agudas ou crônicas e se associar com a chamada síndrome plurimetabólica....

Adiposidad abdominal y resistencia a la insulina al finalizar el primer trimestre de la gestación
Abdominal Adiposity and Insulin Resistance at the End of the First Trimester of Gestation

Introducción: La adiposidad central como factor desencadenante de resistencia a la insulina precoz constituye una amenaza potencial de riesgo metabólico y cardiovascular en el embarazo. Objetivo: Determinar la capacidad discriminante de las grasas abdominales sobre la resistencia a la insulina, diag...

Dimorfismo sexual de la leptina, resistencia a la insulina y composición corporal en prepúberes normopeso

Rev. chil. pediatr; 91 (6), 2020
INTRODUCCIÓN: La etapa prepuberal es un periodo crítico del desarrollo de la grasa corporal, en el cual la leptina y la resistencia a la insulina han sido asociados, sin embargo, hay pocos estudios en prepúberes normo- peso. OBJETIVO: Evaluar la relación de leptina con composición corporal y resiste...

Índice glucosa-triglicéridos como marcador de resistencia a la insulina en pacientes con diagnóstico de hipertensión arterial esencial

Rev. cuba. med; 59 (1), 2020
Introducción: El índice glucemia-triglicéridos se utiliza para el diagnóstico presuntivo de la resistencia insulínica, que en los pacientes hipertensos se relaciona con la severidad de la hipertensión arterial. Objetivo: Determinar la utilidad del índice glucemia-triglicéridos como marcador de...

Relationships among oncostatin M, insulin resistance, and chronic inflammation: a pilot study

ABSTRACT Objective Activated macrophages (M1-type macrophages) in adipose tissue secrete many proinflammatory cytokines that induce insulin resistance (IR). Oncostatin M (OSM), a member of the interleukin-6 (IL-6) family of Gp130 cytokines, plays an important role in a variety of biological functions, ...

NLRP3 inflammasome in metabolic syndrome

Metabolic syndrome (MS) is a serious health problem worldwide; it is characterized by a group of metabolic disorders, including central obesity, insulin resistance/type 2 diabetes, hyperlipidemia with accelerated atherosclerosis, hypertension, non-alcoholic fatty liver disease, and elevated uric acid wit...

Reduction of oxidative stress improves insulin signaling in cardiac tissue of obese mice

ABSTRACT Objective To evaluate the effects of oxidative stress on insulin signaling in cardiac tissue of obese mice. Methods Thirty Swiss mice were equally divided (n=10) into three groups: Control Group, Obese Group, and Obese Group Treated with N-acetylcysteine. After obesity and insulin resistance w...

Muscular resistance, hypertrophy and strength training equally reduce adiposity, inflammation and insulin resistance in mice with diet-induced obesity

ABSTRACT Objective To evaluate the effect of three types of muscular resistance training on adiposity, inflammation levels and insulin activity in Swiss mice with fat-rich diet-induced obesity. Methods Lean and obese male Swiss mice were selected and allocated to one of eight groups comprising eight ...

Insulin signaling in the whole spectrum of GH deficiency

ABSTRACT GH is one of the insulin counterregulatory hormones which acts in the opposite way to insulin, increasing the glucose production by the liver and kidneys and decreasing glucose uptake from peripheral tissues, thus being a hyperglycemic hormone. When in excess, as in acromegaly, it induces glucos...
