The Somogyi hypothesis: a parallelism with Michael Somogyi's life.

Michael Somogyi (Somogyi Mihály, 1883-1971) was a Hungarian biochemist who developed his scientific career in Europe and, primarily, the United States. He gave the name to the eponymous Somogyi effect or Somogyi hypothesis (in short, rebound hyperglycemia after insulin-induced hypoglycemia, particularly nocturnal), which was an axiom in the treatment of diabetes for decades. Although it is currently debated whether the Somogyi hypothesis is a real or relevant phenomenon in patients with diabetes, Somogyi's other significant career achievements are often overlooked.

Exploring differential miRNA expression profiles in muscular and visceral adipose tissue of patients with severe obesity.

Background: This study aims to investigate the differential miRNA expression profile between the visceral white adipose tissue and the skeletal muscle of people with obesity undergoing bariatric surgery.

Methods: Skeletal muscle and visceral adipose tissue samples of 10 controls and 38 people with obesity (50% also with type 2 diabetes) undergoing bariatric surgery were collected. miRNA expression profiles were analyzed using Next-Generation Sequencing and subsequently validated using RT-PCR.

Hypoglycemia during hyperosmolar hyperglycemic crises is associated with long-term mortality.

Background: Previous research has indicated that hypoglycemia during hospitalization is a predictor of unfavorable outcomes in patients with diabetes. However, no studies have examined the long-term impact of hypoglycemia in adults admitted for hyperglycemic crises. The study was aimed to investigate the long-term implications of hypoglycemia during hyperosmolar hyperglycemic crises, particularly in terms of all-cause mortality.

Metformin and Glucose Concentration as Limiting Factors in Retinal Pigment Epithelial Cell Viability and Proliferation.

Metformin is a well-established drug for the treatment of type 2 diabetes; however, the mechanism of action has not been well described and many aspects of how it truly acts are still unknown. Moreover, regarding in vitro experiments, the glycaemic status when metformin is used is generally not considered, which, added to the suprapharmacological drug concentrations that are commonly employed in research, has resulted in gaps of its mechanism of action. The aim of this study was to determine how glucose and metformin concentrations influence cell culture.

Circulating miRNA expression in long-standing type 1 diabetes mellitus.

Type 1 diabetes is a chronic autoimmune disease which results in inefficient regulation of glucose homeostasis and can lead to different vascular comorbidities through life. In this study we aimed to analyse the circulating miRNA expression profile of patients with type 1 diabetes, and with no other associated pathology. For this, fasting plasma was obtained from 85 subjects.

A long non-coding RNA that harbors a SNP associated with type 2 diabetes regulates the expression of gene in pancreatic beta cells.

Introduction: Most of the disease-associated single nucleotide polymorphisms (SNPs) lie in non- coding regions of the human genome. Many of these variants have been predicted to impact the expression and function of long non-coding RNAs (lncRNA), but the contribution of these molecules to the development of complex diseases remains to be clarified.

Methods: Here, we performed a genetic association study between a SNP located in a lncRNA known as LncTGM2 and the risk of developing type 2 diabetes (T2D), and analyzed its implication in disease pathogenesis at pancreatic beta cell level.

miR-24-3p and Body Mass Index as Type 2 Diabetes Risk Factors in Spanish Women 15 Years after Gestational Diabetes Mellitus Diagnosis.

Gestational diabetes mellitus (GDM) is defined as any degree of glucose intolerance that is diagnosed for the first time during pregnancy. The objective of this study is to know the glucose tolerance status after 15 years of pregnancy in patients diagnosed with gestational diabetes and to assess the long-term effect of GDM on the circulating miRNA profile of these women. To answer these, 30 randomly selected women diagnosed with GDM during 2005-2006 were included in the study, and glucose tolerance was measured using the National Diabetes Data Group criteria.

Correlation between glucose measurement parameters of continuous flash monitoring and HbA1c. Real life experience in Asturias.

Introduction: Despite continuous glucose monitoring having been proven useful in patients with type 1 diabetes mellitus, A1C remains the gold standard for assessing disease management.

Material And Methods: Descriptive, retrospective study which included 252 patients, 40.5% male, mean age 44.

Prevalence of diabetes mellitus in Spain in 2016 according to the Primary Care Clinical Database (BDCAP).

The prevalence of type 2 diabetes mellitus is increasing worldwide, including in Spain, and this disease has become a major challenge for health care. In Spain, the computerization of medical records in primary care, in the Primary Care Clinical Database (BDCAP), has made possible the diagnoses of diabetes in a representative sample of the nation as a whole. This article analyzes the prevalence of diabetes recorded in this database and compares the data of the different autonomous communities.

Estimation of body fat mass using the CUN-BAE index and mortality risk by sex in the Asturias Study cohort.

Introduction And Objectives: In epidemiological studies, excess body fat (BF) has been associated with cardiometabolic risk factors, some types of cancer, and other causes of death. A new anthropometric method has been defined: The CUN-BAE index (University of Navarra Clinic-Body Fat Estimator), which is based on BMI, sex, and age. BMI and CUN-BAE index were used to assess their contribution to mortality risk from any cause in the Asturias Study cohort.

[Gender differences in the mortality of people with type 2 diabetes: Asturias Study 2018].

Objective: To investigate the influence of gender on mortality according to the presence or absence of type 2 diabetes mellitus (DM2) and other cardiovascular risk factors in the Asturias Study cohort.

Method: The Asturias Study (started in 1998) is an observational, prospective cohort study of a representative sample of a population of Asturias aged 30-75 years. The population was divided into groups according to the presence or absence of DM2 and according to gender to assess control of cardiovascular risk factors.

Iodine nutrition in pregnant women from Oviedo area. Is iodine supplementation necessary?

Background And Objective: In Asturias, where iodine deficiency was eradicated in school children by the year 2000, iodine deficiency persisted in pregnant women, who were recommended to use of iodine supplementation. The aim of this study was to determine the iodine nutrition of pregnant women in our area and whether or not iodine supplements are needed.

Material And Methods: Throughout May and June 2013 we studied the iodine nutrition and thyroid function during the first trimester of pregnancy in 173 women in the health area of Oviedo.
