Roux-en-Y gastric bypass (RYGB) is an effective treatment for weight loss in patients with morbid obesity. However, few studies have assessed its long-term efficacy in super-obese patients. The study objective was to analyse the long-term effectiveness of RYGB and its effect on improvement of comorbidities after 10 years of follow-up, and to compare the results depending on baseline BMI (<50kg/mvs ≥50kg/m).

Type 2 diabetes mellitus (T2DM) is a chronic, highly prevalent disease that increases with age. Because of this, and due to its chronic complications, T2DM causes high human, social, and financial costs. In addition, the elderly population with T2DM has a marked clinical heterogeneity.

Hospital malnutrition is a highly prevalent problem that affects patient morbidity and mortality resulting in longer hospital stays and increased healthcare costs. Although there is no single nutritional screening method, subjective global assessment (SGA) may be a useful, inexpensive, and easily reproducible tool.
A cross-sectional, observational, randomized study was conducted in 197 patients in a tertiary hospital.

Obesity-associated nonalcoholic fatty liver disease (NAFLD), covering from simple steatosis to nonalcoholic steatohepatitis (NASH), is a common cause of chronic liver disease. Aberrant production of adipocytokines seems to play a main role in most obesity-associated disorders. Changes in adipocytokines in obesity could be mediated by alterations in cyclic GMP (cGMP) homeostasis.

Peripheral polyneuropathy (PN) is a frequent complication of diabetes. However, mechanisms underlying the development of PN are multifactorial and not well understood. Our aim was to examine the association of plasma homocysteine (Hcy) with the prevalence and grade of peripheral PN in patients with type 2 diabetes (T2DM).

To assess the contribution of hyperammonemia and inflammation to induction of mild cognitive impairment (or MHE). We analyzed the presence of mild cognitive impairment (CI) by using the PHES battery of psychometric tests and measured the levels of ammonia and of the inflammatory cytokines IL-6 and IL-18 in blood of patients with different types of liver or dermatological diseases resulting in different grades of hyperammonemia and/or inflammation. The study included patients with 1) liver cirrhosis, showing hyperammonemia and inflammation; 2) non-alcoholic fatty liver disease (NAFLD) showing inflammation but not hyperammonemia; 3) non-alcoholic steatohepatitis (NASH) showing inflammation and very mild hyperammonemia; 4) psoriasis, showing inflammation but not hyperammonemia; 5) keloids, showing both inflammation and hyperammonemia and 6) controls without inflammation or hyperammonemia.

to investigate the association of C677T polymorphism in the methylene tetrahydrofolate reductase (MTHFR) gene, homocysteine plasma values (Hcy), and plasma HDL cholesterol in heterozy-gous familial hypercholesterolemia (hFH).
One hundred and twenty-five hFH subjects were studied. Plasma lipid, lipoprotein, vitamin B12, folic acid and Hcy values were determined.

To evaluate the efficacy and safety of the association of repaglinide, metformin and bedtime NPH insulin compared to two classic regimens: metformin plus NPH and two doses of NPH in patients with poorly controlled type 2 diabetes despite two or more oral antidiabetic drugs (OADs).
Random, parallel and open study of 24 weeks with 37 patients randomized into three therapeutic groups: group A (n=12) (repaglinide/metformin/NPH), group B (n=12) (metformin/NPH) and group C (n=13) (NPH/NPH). The insulin was adjusted in the visits to obtain a basal blood glucose <110 mg/dl.

Familial hypercholesterolaemia (FH) is an autosomal dominant disease characterized by elevated levels of low-density lipoprotein-cholesterol (LDL-C). Phenotypic expression is highly variable, being influenced by diet, age, gender, body mass index, apolipoprotein E genotype and type of LDL-receptor gene mutation. Microsomal triglyceride (TG) transfer protein (MTP) is a protein involved in lipid metabolism.
