The relationship between nutritional status and white matter integrity in older adults: A diffusion tensor imaging study.

Objectives: The purpose of this study to determinate whether there is a relationship between the nutritional status and white matter integrity in older patients by using Diffusion Tensor Imaging (DTI).

Methods: The patients were evaluated by Mini-Nutritional Assessment Scale. The patients are categorized in the groups of well-nourished, risk of malnutrition, or malnourished, depending on the overall score> 23.

Evaluation of white matter integrity by diffusion tensor imaging in the deficiencies of vitamin B12 and folate in older patients.

Objectives: The aim of this study is to investigate whether white matter (WM) integrity is impaired in vitamin B12 and folate deficiency with Diffusion Tensor Imaging (DTI) in older patients.

Methods: All the patients aged ≥65 years admitted to the geriatric clinic and performed DTI-MRI were included in the study. DTI parameters (fractional anisotropy, mean diffusivity, axial diffusivity, radial diffusivity) were calculated by ROI-based method in white matter tracts.

The prevalence of undernutrition and associated factors in older obese patients.

Background: Both obesity and malnutrition are common health problems in older adults.

Aim: The aim of our study is to investigate the prevalence of undernutrition and related factors in older obese patients.

Methods: 1911 older outpatients who underwent comprehensive geriatric assessment were included in this cross-sectional study.
