Epidemiological studies have shown that plasma SHBG levels correlate with plasma adiponectin levels, both in men and women. To the best of our knowledge there are no reports describing any molecular mechanism by which adiponectin regulates hepatic SHBG production. The aim of the present study is to explore whether adiponectin regulates SHBG production by increasing HNF-4α levels through reducing hepatic lipid content. For this purpose, in vitro studies using huma...

Introduction: Over the last few years, there are some studies that suggests a close connection between Nonalcoholic Liver Disease (NAFLD) and increased cardiovascular (CV) risk in population with obesity. Indeed, these two conditions share common drivers, most notably insulin resistance and other elements of the metabolic syndrome. Notwithstanding the above, this affirmation does not have solid scientific evidence. The proliferation of Vasa Vasorum (VV) in the adventitial laye...

Background and aims: There are growing evidence supporting the deleterious effect of type 2 diabetes (T2D) on respiratory function and sleep breathing disorders. However, there is no information about the characteristics of lung function in the prediabetes stage.Methods: We assessed pulmonary function in 3,455 non-diabetic subjects, aged between 45 and 70 years, without vascular disease nor chronic pulmonary obstructive disease from the cross-sectional s...

Background: An association of pregnancy outcomes with subclinical hypothyroidism have been reported, however, there still exists a strong controversy regarding whether subclinical hypothyroidism ought to be dealt with or not. The latest American Thyroid Association’s guideline gives support to a higher TSH upper reference range of 4 mIU/l than the one proposed a few years ago of 2.5 mIU/l for the first trimester of pregnancy, in the absence of local normal ranges of TSH. ...

Results: Main clinical, analytical and polygraphic data: 58.1±6.4 years, body mass index 32.4±5.4 kg/m2, 70.4% female, HbA1c 8.0±1.9%, AIH 27.4 events/hour (in the range of severe sleep apnea and hypoapnea index), and CT90% 32.9%. Nocturnal concentration of urine total metanephrines were higher than diurnal levels (226±12 vs 98±13 μg/l; P=0.085). In addition, its nocturnal concentration was significantly associated, in a positi...

Introduction: The autosomal dominant multiple endocrine neoplasia type 1 (MEN1), characterized by parathyroid hyperplasia (PH), neuroendocrine digestive tumours (NET) and pituitary adenomas (PA), is due to mutations in the tumor suppressor gene MEN1 encoding a 610-amino acid protein, menin. Guidelines recommend MEN1 mutational analysis in index cases with two or more MEN1-associated tumours, in first-degree relatives of mutation carriers and when clinical dat...

Introduction: Obesity and its comorbidities, specially type 2 diabetes (T2D), are a major public health problem. The disappointing result of dietary treatment and the scarce of drugs have led to increased bariatric surgery (BS) as the most efficient therapeutic option. However, not all obese patients with T2D who undergo BS achieve diabetes remission.Objective: To develop a genetic scoring system for predicting T2D remission following BS. 2) To compare o...
