Endogenous and exogenous factors play a role in endothelial dysfunction. Inflammation, leukocyte adhesion-aggregation, abnormal vascular proliferation, atherosclerosis, and hypertension are among the endogenous factors. Another factor that affects endothelial dysfunction is exogenous factors such as drug treatments, smoking, alcohol, and nutrition.

Article Synopsis
  • - The study examines how different fat diets and exercise impact biological aging markers, focusing on telomere length, inflammation, and oxidative stress in rats.
  • - Researchers divided 48 rats into six groups to test the effects of unsaturated vs. saturated fat diets and aerobic exercise over 50 days, measuring various biological markers and telomere lengths.
  • - Results showed that unsaturated fat diets and physical activity were linked to longer telomeres and better inflammatory status, while saturated fat diets correlated with higher body weight gain and unfavorable biological markers.

Background: White tea, derived from the Camellia sinensis plant like other teas, uses tender buds and young leaves and undergoes minimal processing. This results in higher levels of antioxidants and bioactive substances, which may enhance thermogenesis more effectively than other teas. This first human study aimed to investigate the acute effects of white tea consumption on resting energy expenditure (REE) and some vital signs, including blood pressure (BP), heart rate (HR), and body temperature (BT).

Article Synopsis
  • * Recent research highlights propolis for its potential in body weight management by enhancing energy expenditure and utilizing key phenolic components like artepillin C and quercetin to combat obesity-related mechanisms.
  • * Propolis shows promise as a natural method for preventing obesity, addressing a significant contemporary health issue by activating metabolic pathways that aid in fat metabolism.

Context: Since pregnancy is a decisive period for women and children in terms of future health, it is very important to determine changes in energy expenditure and requirements. However, there is no reference method to determine the energy expenditure as there are many factors that change maternal energy homeostasis during this period.

Objective: This review aims to evaluate the changes in energy expenditure during pregnancy and the effects of these changes on maternal weight gain, as well as the methods used to determine energy expenditure.

Nitrite, nitrate, and their salts are added to processed meat products to improve color, flavor, and shelf life and to lower the microbial burden. N-Nitrosamine compounds are formed when nitrosing agents (such as secondary nitrosamines) in meat products interact with nitrites and nitrates that have been added to the meat. With the consumption of such meat products, nitrosation reactions occur in the human body and N-nitrosamine formation occurs in the gastrointestinal tract.

Background: The present study aimed to evaluate the effects of fermented oligosaccharide, disaccharide, monosaccharide and polyols (FODMAP) diet therapy and probiotics on irritable bowel syndrome (IBS) symptoms, quality of life and depression in women diagnosed with IBS.

Methods: For the study, 52 female IBS patients between the ages of 20 and 55 were enrolled. Individuals were monitored for 6 weeks in two groups.

Purpose Of Review: Considering the increase in life expectancy, there is a time-related decline in biological functions. Age-related changes are also observed in the circadian clock which directly leads to appropriate rhythms in the endocrine and metabolic pathways required for organism homeostasis. Circadian rhythms are affected by the sleep/wake cycle, environmental changes, and nutrition.

Objective: To determine the prevalence of sarcopenia in patients with chronic kidney disease (CKD), investigate the relationship of the serum myostatin level with sarcopenia and inflammatory markers.

Methods: The study was conducted with four patient groups: renal transplantation (TX), stage 3-5 non-dialysis-dependent CKD (NDD-CKD), hemodialysis (HD), and peritoneal dialysis (PD). Laboratory parameters, serum myostatin, C-reactive protein, and interleukin-6 levels were studied.

Background: Hospital malnutrition is an important health problem for developed and developing countries, and screening tools are recommended in practice because they can be obtained quickly and easily to identify the risk of malnutrition. This study aimed to validate the use of the Graz Malnutrition Screening (GMS) in combination with different methods of nutrition assessment in the identification of malnutrition risk in hospitalized adult and older patients.

Methods: The study was performed with a total of 348 adult (64.

Objective: We aimed to evaluate the agreement between the resting energy expenditure (REE) obtained by indirect calorimetry and eight prediction equations in adult patients with renal transplantation and a newly developed REE prediction equation for use in patients with renal transplantation in the clinic.

Methods: A total of 51 patients (30 males and 21 females) were involved in the study. The REE was measured by indirect calorimetry and compared with the previous prediction equations.

In recent years, individuals have begun to tend more frequently to some natural and herbal products to be used alone or as a combination with diet and exercise for ensuring the weight loss. Green tea is the leading one of these products. In some studies, it is reported that the green tea causes an increase in thermogenesis and substrate with fat oxidation by affecting on the sympathetic nervous system.

Background/aim: To investigate the effect of dietary salt restriction on blood pressure levels, total sodium removal, and hydration status of peritoneal dialysis (PD) patients.

Materials And Methods: Thirty-one stable PD patients who consulted a renal dietitian monthly for dietary recommendations, including restricted salt intake <5 g/day, and education about hypertension and hypervolemia were included in this study. Baseline and third month clinical and laboratory findings, bioelectrical impedance analysis results, and urinary and peritoneal sodium removal values were recorded.

Peritoneal dialysis (PD) patients are often volume-expanded and have higher-than-normal blood pressure (BP) levels. In the present study, we aimed to investigate the role of fluid balance and salt intake for BP control in our PD patients. The study included 37 patients undergoing PD and having complete data for 3 consecutive months.

Introduction: This study was planned to investigate the relation between dietary macronutrient status and anthropometric measurements in peritoneal dialysis (PD) patients.

Materials And Methods: A total of 28 clinically stable patients were enrolled in this study. All patients were taken a dietary therapy according to the guidelines of the American Journal of Kidney Foundation for 12 weeks.
