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).

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.

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).

Impact of Percutaneous Endoscopic Gastrostomy (PEG) on the Evolution of Disease in Patients with Amyotrophic Lateral Sclerosis (ALS).

Dysphagia is a highly prevalent symptom in Amyotrophic Lateral Sclerosis (ALS), and the implantation of a percutaneous endoscopic gastrostomy (PEG) is a very frequent event. The aim of this study was to evaluate the influence of PEG implantation on survival and complications in ALS. An interhospital registry of patients with ALS of six hospitals in the Castilla-León region (Spain) was created between January 2015 and December 2017.

Material and methods: from January 1, 2018 to December 31, 2019 the home enteral nutrition registry was recorded, and afterwards a further descriptive and analytical analysis was done. Results: in 2018, 4756 active patients were registered and the prevalence was 101.

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.

[Pillars for excellence in nutrition support units. Training].

Few areas of current medicine have undergone change and evolution in recent years such as those of clinical nutrition. Currently, 98 % of endocrinology and nutrition departments in hospitals with 500 or more beds incorporate a clinical nutrition and dietetics Unit. The training of the professionals that integrate these units has been and will be a key point in their ongoing development towards excellence.

Postoperative enteral immunonutrition in head and neck cancer patients: Impact on clinical outcomes.

Background: Head and neck cancer patients have a high rate of complications during the postoperative period that could increase their morbidity rate. Arginine has been shown to improve healing and to modulate inflammation and immune response. The aim of our study was to assess whether use of arginine-enriched enteral formulas could decrease fistulas and length of stay (LoS).

[Integral approach to the older patient with cancer].

The world population, as well as the number of elderly people, grow exponentially. Elderly individuals are at a higher risk of developing an oncological disease, especially because they are subject to a longer period of exposure to carcinogens, and a worse capacity for regeneration of their deoxyribonucleic acid (DNA) (1). Cancer in elderly individuals represents 80% of the annual deaths secondary to this pathology (2).

Introduction: oncohematological diseases are associated with a high prevalence of malnutrition during hospitalization. Our aim was to analyze the appearance and repercussions of malnutrition in well-nourished hematological inpatients at admission. Method: a prospective one-year study conducted in hematology inpatients.
