Kidney transplantation is usually performed as a preferred treatment and last resort in chronic kidney disease after the end stage of renal disease. Considering that nutrition can play an essential role in post-transplant recovery, the aim of this study was to review the nutritional assessment and dietary requirements of kidney transplant patients. Articles were collected via searching in databases such as PubMed-Medline, Google Scholar, Scopus, and Web of Science using relevant keywords and phrases, including kidney transplantation, end stage renal disease, nutrition, dietary intake, nutritional assessment, and nutrition evaluation. Medical nutrition therapy can play a vital role in the recovery after transplantation in kidney failure patients. It seems that nutritional and medical evaluation through laboratory methods, vital signs, and anthropometric measurements are necessary to improve the quality of nutritional interventions after kidney transplantation and can help to decrease the risk of kidney transplant rejection, therefore periodic evaluation and follow-up of these patients can lead to beneficial results.

We aimed to investigate whether the elderly living in Tabriz, Iran meet the requirements for energy and macronutrients intake, and to examine the relationship of their dietary intake to cognitive function.

In this cross-sectional study, 164 elderly subjects aged 65 years and older were enrolled. Anthropometric and dietary parameters were measured. The cognitive performance was assessed using Mini Mental State Examination (MMSE) and compered between males and females. The associations of energy, BMI, and macronutrients with cognitive function were also investigated.

About half of the participants (n=83, 50.6%) had BMI in normal range, 22.6% (n=37) were underweight, while 26.8% (n=44) were overweight/obese. Average daily energy intake was 1235.21 (360.89) kcal/day; in 87 (53%) of the elderly, total energy intake was lower than the recommended intake. The subjects consumed 0.77g protein/kg body weight. Fat intake <20-35% (the recommended values) was observed in 93.3% (n=153) of the participants. Additionally, 123 cases (76.4%) suffered from cognitive impairment. A significant difference was also found between genders for cognitive status (p<0.001). A significant association of BMI and fat and protein intake was found with cognitive function.

This study revealed that a relatively high percentage of the elderly had inadequate and unbalanced nutritional intake. Additionally, the degree of cognitive decline was remarkable in the studied subjects. There was a relationship between dietary intake and cognitive performance. Due to the higher vulnerability to nutritional deficiencies and cognitive impairments of the elderly, more attention of health professional to nutritional and cognitive status is warranted.
