Phase angle: Differences between disease-related malnutrition, obesity and healthy people.

Introduction: Bioelectrical Impedance Analysis (BIA) is a tool used in clinical nutrition and pure electrical data such as phase angle (PA) has shown prognostic value. It relates resistance and reactance indicating cellular health.

Objective: To determine differences in PA between patients with obesity and disease-related malnutrition (DRM) compared to the healthy population, and to establish associations between PA and other body composition (BC) parameters.

Prevalence of sarcopenic obesity according to different diagnostic methods and cut-off points in candidates for bariatric surgery.

Background And Aims: Sarcopenic obesity (SO) is defined as a combination of low strength and muscle mass along with excess adiposity. Our study aimed to determine the prevalence of sarcopenic obesity in candidates for bariatric surgery, according to ESPEN/EASO criteria using bioimpedance analysis (BIA) and dual-energy X-ray absorptiometry (DXA).

Methods: Retrospective study of adult patients (18-60 years) candidates for bariatric surgery (BMI ≥40 kg/m or ≥35 kg/m with associated complications).

Dysphagia as a primary manifestation of basilar impression: A case report.

Secondary basilar invagination or basilar impression is an anomaly at the craniovertebral junction where the odontoid process prolapses into the foramen magnum with the risk of compressing adjacent structures and obstructing the proper flow of cerebrospinal fluid (CSF). The incidence is less than 1% in the general population and occurs mainly in the first three decades of life when it is associated with malformations of the neuroaxis. In older age, the main aetiologies are diseases that alter bone mineral density.

Utility of abdominal ultrasound for the diagnosis of hepatic steatosis in patients with morbid obesity.

Metabolic dysfunction-associated fatty liver disease is the most common cause of liver disease in our environment. The gold standard for diagnosis continues to be liver biopsy, although, since it is an invasive test, the most commonly used test for the initial diagnosis of steatosis is abdominal ultrasound. We present the results on the diagnostic utility of ultrasound for the detection of steatosis in the population of morbidly obese patients who underwent bariatric surgery from 2004 to 2019 in our centre.

Is Food Tolerance Different After Bariatric Surgery Depending on the Surgical Procedure?

Background: Bariatric surgery (BS) is a very effective treatment regarding body weight loss but might affect food tolerance and energy and protein intake. The aim of this study was to compare three BS techniques (biliopancreactic diversion (BPD), gastric bypass (GB), and sleeve gastrectomy (SG)) and their effect on food tolerance.

Methods: Prospective study conducted between April 2016 and April 2019.

[Assessment of low muscle mass and strength in a control population].

Background and aims: low muscle mass (LMM) conditions the nutritional status of an individual and has implications for quality of life and prognosis. The aim of this study was to evaluate body composition and determine normal values in the diagnosis of LMM in a control group of healthy individuals. Methods: a cross-sectional study of healthy volunteers aged 18 to 45 years with body mass index (BMI) < 30 kg/m2.

Disease-Related Malnutrition and Sarcopenia Predict Worse Outcome in Medical Inpatients: A Cohort Study.

(1) Background: Both sarcopenia and disease-related malnutrition (DRM) are unfortunately underdiagnosed and undertreated in our Western hospitals, which could lead to worse clinical outcomes. Our objectives included to determine the impact of low muscle mass (MM) and strength, and also DRM and sarcopenia, on clinical outcomes (length of stay, death, readmissions at three months, and quality of life). (2) Methodology: Prospective cohort study in medical inpatients.

Bioelectrical impedance analysis as an alternative to dual-energy x-ray absorptiometry in the assessment of fat mass and appendicular lean mass in patients with obesity.

Objective: Obesity is a challenge for bioelectrical impedance analysis (BIA) estimations of skeletal muscle and fat mass (FM), and none of the equations used for appendicular lean mass (ALM) have been developed for people with obesity. By using different equations and proposing a new equation, this study aimed to assess the estimation of FM and ALM using BIA compared with dual-energy x-ray absorptiometry (DXA) as a reference method in a cohort of people with severe obesity.

Methods: This cross-sectional study compared a multifrequency BIA (TANITA MC-780A) versus DXA for body composition assessment in adult patients with severe obesity (body mass index [BMI] of >35 kg/m).

Diabetes remission after malabsorptive bariatric surgery.

Obesity and diabetes are two closely related disorders. Lifestyle changes and drug treatment do not achieve successful diabetes remission. A treatment option for these patients is bariatric surgery (BS).

Evaluation of Lipoprotein Profile and Residual Risk Three Years After Bariatric Surgery.

Introduction: Obesity is a chronic disease associated with other comorbidities, including atherogenic dyslipidemia (AD). Bariatric surgery (BS) has shown to reduce cardiovascular risk (CVR) by achieving a significant weight reduction and improving the lipid profile. Different surgical techniques may have a different effect on the lipoprotein profile.

Effects of physical exercise in sarcopenia. A systematic review.

From the third decade of life and due to multiple causes, muscle mass and strength are gradually lost, which affects the function of the musculoskeletal system. This combined loss of muscle mass and strength with aging is called sarcopenia, and is associated with greater morbidity and mortality in the elderly. Early treatment is therefore essential, and physical exercise is the therapeutic approach that has given the best results.

[Role of prebiotics and probiotics in the functionality of the microbiota in the patients receiving enteral nutrition].

Set of resident microorganisms in our body that are responsible for the absorption of nutrients and the maintenance of health is named microbiota. The microbiota´s role is protective, trophic and metabolic. Different groups of microbiota intestinal name enterotypes, each one of them are in relation to specific dietary habits.
