Abstract In the present study, we characterized distinctive signatures of gut microbiota (GM) from overweight/obese patients (OB), and normal-weight controls (NW), both Sardinian origin. Fecal bacterial composition 46 OB (BMI = 36.6 ± 6.0; F/M 40/6) was analyzed compared to that NW subjects 21.6 2.1; 41/5), matched for sex, age smoking status, by using 16S rRNA gene sequencing on MiSeq Illumina platform. The microbial community exhibited a significant decrease in relative abundance several...

This study was aimed at characterizing the gut microbiota (GM) and its functional profile in two groups of Sardinian subjects with a long healthy life expectancy, overall named Long-Lived Subjects (LLS) [17 centenarians (CENT) 29 nonagenarians (NON)] by comparing them to 46 younger controls (CTLs). In addition, contribution genetics environmental factors GM phenotype assessed subgroup seven centenarian parents (CPAR) paired cohort centenarians' offspring (COFF). The analysis performed...

Background/Objectives: Managing type 2 diabetes mellitus (T2DM) and obesity requires a multidimensional, patient-centered approach including nutritional interventions (NIs) physical activity. Changes in the gut microbiota (GM) have been linked to metabolic alterations typical of T2DM obesity, they are strongly influenced by diet. However, few studies evaluated effects on GM very-low-calorie ketogenic diet (VLCKD) patients with T2DM, especially mid-term long-term. This longitudinal study is...

Type 2 diabetes mellitus (T2DM), the most common form of diabetes, is a progressive chronic metabolic disease that has increasingly spread worldwide, enhancing mortality rate, particularly from cardiovascular diseases (CVD). Lifestyle improvement through diet and physical activity is, together with drug treatment, cornerstone T2DM management.

Thyroid function was evaluated in 150 Sardinian outpatients at different stages of lithium treatment. A visible and/or palpable goitre found 51% patients, and there no apparent correlation with the duration No cases symptomatic hypothyroidism were observed, but subclinical present 19% patients. The prevalence specific antithyroid antibodies positively correlated age treatment, higher women. Subclinical observed 53% antibody-positive lithium-treated Carbamazepine combination associated...

We sought to reevaluate the prevalence of thyroid dysfunction and autoimmunity in 47 patients with celiac disease; 91 healthy subjects were studied as controls. Both controls from Sardinia, Italy.Diagnosis disease was made on basis clinical history, presence positive antigliadin IgA (AGA-A) IgG (AGA-G) antibodies, antireticulin antibodies (ARA), antiendomysium (EMA), confirmed by jejunal biopsy.
