Equations for Assessing Body Composition by Ultrasound in Older Adults: A Narrative Review.

As individuals age, physiological changes in body composition occur, potentially contributing to adverse health outcomes in the elderly population. Various methods are used to assess body composition, but gold-standard techniques often involve technical complexity, high costs, and lack of portability. Alternative methods that are portable, relatively low-cost, and technically simpler are necessary for clinical use.

Validity and reliability of Gripwise digital dynamometer in the assessment of handgrip strength in older adults.

Introduction: With the advancement of studies on the importance of sarcopenia in the aging process, new technologies have been developed to assess muscle mass and function. However, most research on portable devices has not considered a wide range of ages and clinical conditions. This study aimed to evaluate the reliability of the Gripwise digital dynamometer in measuring handgrip strength in older Brazilian adults, comparing its performance with the widely used Saehan device.

Cooking for Health: a comprehensive narrative review of Culinary Medicine as an educational tool in medical training in Brazil and Globally.

The poor diet quality in line with the rising prevalence of noncommunicable chronic diseases, coupled with the substantial deficit in nutritional education within medical training programs, has precipitated the emergence of Culinary Medicine as an evolving discipline. Culinary Medicine fuses the art of home cooking with the sciences of human nutrition, psychology, gastronomy, and medicine to promote health and well-being. This comprehensive narrative review explores the diverse facets of Culinary Medicine, elucidating its historical evolution, theoretical foundations, educational initiatives in Brazil and worldwide, and its practical implementation in clinical contexts.

We aimed to evaluate the intra- and inter-rater reliability of two evaluators using A-mode Portable Ultrasound to measure muscle and fat thickness in Brazilian older adults.

Short-chain fatty acids are associated with adiposity, energy and glucose homeostasis among different metabolic phenotypes in the Nutritionists' Health Study.

Background And Aims: The gut microbiome is associated with obesity, mainly mediated by bacteria-produced short-chain fatty acids (SCFAs). It is unknown how SCFA concentrations are associated with the phenotypes metabolically healthy normal weight (MHNW), metabolically unhealthy normal weight (MUNW), metabolically healthy obese/overweight (MHO), and metabolically unhealthy obese/overweight (MUO). We compared plasma and fecal SCFA concentrations among adult women categorized according to the metabolic phenotypes mentioned above and examined associations between SCFA and adiposity and components of energy and glucose homeostasis.
