“…A major benefit of sunlight exposure is its role in synthesizing vitamin D in the skin [9,10]. Although there are differences depending on the time of day, season, latitude, and individual sensitivity to sunlight, 3000 international units of vitamin D can be synthesized when an arm or leg is exposed to sunlight for five to ten minutes [11].…”

Sunlight exposure has been reported to have various beneficial effects on human health. This study investigated the relationship between self-rated health status, psychosocial stress, eating behaviors, and food intake according to sunlight exposure in 948 adults. Sunlight exposure was classified as less than one hour, less than three hours, and greater than three hours. Of the participants, 49.2% had fewer than three hours of daily exposure to sunlight. Regarding participants exposed to sunlight for less than one hour, the largest response was that they did not engage in outdoor activities on weekdays or weekends, and the rate of being outdoors in the shade on sunny days was the highest in this group at 42.7%. Furthermore, the participants exposed to sunlight for less than one hour had a lower health response than the other two groups, and there were significantly more participants classified in the stress risk group. Regarding eating habits, those with less than an hour of exposure to sunlight frequently ate fried foods, fatty foods, added salt, and snacks, and had significantly lower total dietary scores or three regular meals. Additionally, their frequency of consumption of cereals, milk and dairy products, orange juice, and pork was also significantly lower than the other groups. Thus, it is necessary to provide sufficient guidelines for adequate sunlight exposure and food intake because participants with low sunlight exposure may have low vitamin D synthesis and insufficient food intake.

“…While malnutrition is detected in approximately one third of these patients, the probability of encountering malnutrition increases as the duration of hemodialysis increases (2). Malnutrition occurs due to various factors reduces the quality of life (3) and increases the risk of morbidity and mortality in HD patients. The guidelines recommend frequent assessment of nutritional status in patients with ESRD (4).…”

Introduction: Malnutrition is a common and important problem in HD Hemodialysis (HD) patients. Malnutrition occurs due to various factors increases the risk of morbidity and mortality in HD patients. The Controlling Nutritional Status (CONUT) score has been designed to assess the nutritional status in patients. In addition, the relationship between the CONUT score and mortality has been investigated. We aimed to investigate the effectiveness of the CONUT score in predicting mortality in HD patients. Material and Method: The data of 110 patients who started HD between 2017-2021 were analyzed retrospectively. From the laboratory parameters were evaluated before starting the first hemodialysis treatment. The CONUT score was calculated based on lymphocyte count, total cholesterol levels, and serum albumin levels. The patients were divided into two groups as CONUT score ≤4 and CONUT score ≥5. The groups were compared regarding these parameters. Results: The data of 110 hemodialysis patients were analyzed. 58 (52.7%) of these patients were male. The mean age of the patients was 53.18±17.10 years. There were 49 (44.5%) patients with a CONUT score of ≤4 and 61 (55.5%) patients with a CONUT score of ≥5. 35 patients (13.9%) died. Among 35 all-cause deaths, 4 (11.4%) were occurred in the low CONUT group, and 31 (88.6%) were occurred in the high CONUT group (p<0.001). According to Kaplan-Meier analysis, the high CONUT group had significantly higher all-cause mortality (p<0.001) than the low CONUT group. According to the correlation analysis, there was a positive correlation between the CONUT score and mortality (p<0.001). In the multivariate Cox regression analysis, all cause of mortality was independently correlated to age, gender (male) and CONUT score (p: 0.010, p: 0.038 and p < 0.001, respectively). According to the ROC curve analysis, the optimal cut-off value of CONUT score in Hemodialysis HD patients was found at 4.5. Conclusion:We concluded that the higher the CONUT score, the worse the nutritional status in hemodialysis patients, and may be associated with worse clinical outcomes. It is extremely important to evaluate the nutritional status at regular intervals, to detect malnutrition early and to follow up the results in HD patients. We think that CONUT score can be useful in predicting mortality risk for HD patients in clinical practice.

Background Peritoneal dialysis (PD) is a form of dialysis to replace the function of kidney, that uses the peritoneum as a dialysis membrane to remove metabolites and water retained in the body. Vitamin D deficiency is prevalent in patients treated with PD. This research investigated the correlation between serum 25-hydroxyvitamin D [25(OH)D] concentration and anemia, microinflammation, and oxidative stress in PD patients. Methods 62 PD patients and 56 healthy volunteers were recruited in this research. Serum concentrations of 25(OH)D and basic parameters of anemia were detected. The correlation between serum 25(OH)D concentration with anemia, oxidative stress, and microinflammatory state were analyzed. Results In the PD group, the concentration of 25(OH)D was lower than the healthy control (HC) group (p < 0.001). Hemoglobin, red blood cell count (RBC), and total iron binding capacity (TIBC) in the PD group was significantly lower (all p < 0.001), while high-sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6), and tumor necrosis factor α (TNF-α) concentrations were significantly higher, than the HC group (all p < 0.001). In the PD group, malondialdehyde (MDA) concentration was higher than in the HC group (p < 0.001), while superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) were lower (both p < 0.001). Serum 25(OH)D exhibited positive correlation with hemoglobin (r = 0.4509, p = 0.0002), RBC (r = 0.3712, p = 0.0030), TIBC (r = 0.4700, p = 0.0001), SOD (r = 0.4992, p < 0.0001) and GSH-Px (r = 0.4312, p = 0.0005), and negative correlation with hs-CRP (r = − 0.4040, p = 0.0011), TNF-α (r = − 0.4721, p = 0.0001), IL-6 (r = − 0.5378, p < 0.0001) and MDA (r = − 0.3056, p = 0.0157). Conclusion In conclusion, reduced serum 25(OH)D concentrations in PD patients contribute to anemia, oxidative stress and microinflammatory state.
