The Performance and Associated Risks of the Criteria for Sarcopenic Obesity Proposed by the European Association for the Study of Obesity in a Geriatric Population.

Background: There is no gold standard definition of sarcopenic obesity (SO). Our objective is to evaluate the benefit of using the new definition proposed by the European Association for the Study of Obesity (EASO) in older people.

Methods: Data from the Toledo Study of Healthy Aging, a study based on a cohort of community-dwelling older adults, were used.

Gender-specific capacity of insulin resistance proxies to predict functional decline in older adults.

Objectives: Insulin resistance determined by Homeostasis Model of Insulin Resistance (HOMA-IR) has been associated with functional decline in non-diabetic older subjects. However, insulin is not routinely assessed. The study evaluated the predictive value of non-insulin-dependent IR surrogates on functional decline in non-diabetic older men and women.

Ultrasound Cut-Off Values for Rectus Femoris for Detecting Sarcopenia in Patients with Nutritional Risk.

Background: A nationwide, prospective, multicenter, cohort study (the Disease-Related caloric-protein malnutrition EChOgraphy (DRECO) study) was designed to assess the usefulness of ultrasound of the rectus femoris for detecting sarcopenia in hospitalized patients at risk of malnutrition and to define cut-off values of ultrasound measures.

Methods: Patients at risk of malnutrition according to the Malnutrition Universal Screening Tool (MUST) underwent handgrip dynamometry, bioelectrical impedance analysis (BIA), a Timed Up and Go (TUG) test, and rectus femoris ultrasound studies. European Working Group on Sarcopenia in Older People (EWGSOP2) criteria were used to define categories of sarcopenia (at risk, probable, confirmed, severe).

Relationship of endogenous plasma concentrations of β-hydroxy β-methyl butyrate (HMB) with frailty in community dwelling older adults with type-2 diabetes mellitus.

Background: Supplementation with β-hydroxy β-methyl butyrate (HMB) appears to be effective in preserving muscle in older adults. However, the association between endogenously produced HMB with frailty has not been studied in people with chronic disease.

Objectives: The purpose of this study is to explore whether an association exists between endogenous HMB levels and frailty status in older adults with type-2 diabetes mellitus (T2DM).

Association between endogenous plasma beta-hydroxy-beta-methylbutyrate levels and frailty in community-dwelling older people.

Background: Frailty is a key element in healthy ageing in which muscle performance plays a main role. Beta-hydroxy-beta-methylbutyrate (HMB) supplementation has shown favourable effects in modulating protein synthesis, improving muscle mass and function in interventional studies. Decreased age-related endogenous HMB levels have been shown in previous studies.

Oligomeric Formulas in Surgery: A Delphi and Consensus Study.

Nutritional management of patients with intestinal failure often includes the use of oligomeric formulas. Implementing the use of oligomeric formulas in surgical patients with maldigestion or malabsorption could be a nutritional strategy to be included in clinical protocols. We aim to generate knowledge from a survey focused on the effectiveness of nutritional therapy with oligomeric formulas with Delphi methodology.

[Implementation of an ERAS program in liver surgery].

The perioperative management of patients undergoing abdominal surgery has been based on traditional concepts and often not supported by scientific evidence. Recently there have been several scientific studies showing that some traditional procedures for the perioperative management of patients as preoperative fasting, bowel preparation, use of naso-gastric tubes, placement of intra-abdominal drainage, postoperative fasting etc. They are unnecessary and sometimes counterproductive.

Giant adrenal myelolipoma: case report and literature review.

Adrenal myelolipomas are rare benign tumors comprising mature adipose tissue and diverse hematopoietic elements. These neoplasms are usually incidental findings, although bulky masses can generate abdominal pain as well as other symptoms related to compression of adjacent organs. Diagnosis is usually provided by ultrasonography or computed tomography.

[Functional nutrition and optimal nutrition. Near or far?].

The concept of functional food, about which scientific agreement is still lacking, springs from the field of Optimum Nutrition, aimed at modifying genetic and physiological aspects of human life and at the prevention and treatment of a growing number of diseases, far beyond merely covering nutritional requirements. From the European Union perspective, functional foods can be natural as well as industrially processed foods. The leading functional foods regarding which the soundest scientific evidence exists are probiotics, live microbial food ingredients represented mainly by fermented dairy products.
