Item Combined Therapy with Probiotic VSL#3 and Omega-3 Fatty Acids Attenuates Colonic Injury and Inflammation in Chronic DNBS-induced Colitis in Mice (vol 69, pg 135, 2021)(2022) Ilktac, Havvanur Yoldas; Kiziltan, Gul; Lanpir, Asli Devrim; Ozansoy, Mehmet; Gunal, Mehmet Y.; Togay, Sine Ozmen; Keskin, Ilknur; Ozdemir, Ekrem M.; Kilic, UlkanItem Effect of Nutrition Education on Diet Quality, Sustainable Nutrition and Eating Behaviors among University Students(2021) Yolcuoglu, Irem Zeynep; Kiziltan, Gul; 34330188Objective Nutrition information is provided by proper nutrition education and nutrition education programs have a direct impact on nutrition knowledge and behavior. This study aims to determine the effect of nutrition education on diet quality, sustainable nutrition and eating behavior. Design Cross-sectional survey. Participants The study was carried out on a total of 204 individuals, 21 males and 183 females, who were studying in the 3rd and 4th grades of Baskent University Faculty of Health Sciences. Main outcome measures Mean Adequacy Ratio (MAR) score calculated with the Nutrient Adequacy Ratio (NAR) was used to evaluate the diet quality. 'Sustainable and Healthy Eating Behaviors Scale' was applied to measure sustainable and healthy eating behaviors. Analysis A questionnaire including personal information and anthropometric measurements of the individuals and a 24-hour dietary recall was taken. Food consumption records were evaluated using the Nutrition Information System. In order to evaluate the quality of the diet, the Mean Adequacy Ratio (MAR) score calculated with the Nutrient Adequacy Ratio (NAR) was used. 'Sustainable and Healthy Eating Behaviors Scale' was applied to measure sustainable and healthy eating behaviors. SPSS 20.0 package program was applied to evaluate the data. Results In the study, 47.5% of the individuals were educated in Nutrition and Dietetics program and 52.5% were in other programs. The diet quality of 44.8% of the individuals studying in the Nutrition and Dietetics program and 56.4% of the individuals studying in the other programs were determined as 'good' according to the MAR levels classification. No significant difference was found in terms of MAR levels of individuals according to the departments they read (p > 0.05). The average score of the 'Healthy and Balanced Nutrition' factor in the scale of sustainable and healthy eating behaviors was higher in individuals who were studying in the Nutrition and Dietetics program. The average scores of 'Seasonal Food' and 'Low Fat' factor were found to be significantly higher in girls studying in the Nutrition and Dietetics program (p < 0.05). Conclusion It was determined that nutrition education is effective on sustainable and healthy eating behaviors. Considering the importance of nutrition education on the health of individuals and sustainable environment, it is of great importance in terms of public health to increase the awareness of the society on this issue.Item The Effect of Probiotic and Omega-3 Supplements on Total Oxidant and Total Antioxidant Levels in Experimental Colitis(2021) IIlktac, Havvanur Yoldas; Kiziltan, Gul; Ozansoy, Mehmet; Kilic, Ulkan; Togay, Sine Ozmen; Keskin, Ilknur; Ozdemir, Ekrem Musa; Gunal, Mehmet YalcinObjective: Treatment of inflammatory bowel disease (IBD) usually involves medical therapy. For this reason, it is recommended to seek alternative treatment methods such as nutritional therapy. The aim of the study is to evaluate the effects of probiotics and omega-3 fatty acids on total oxidant and total antioxidant levels in an experimental colitis model. Methods: Mice were randomly divided into five groups (n= 10/group) as healthy group, colitis group, group treated with probiotics (VSL#3), group treated with omega-3 (w-3), and group treated with both probiotics and omega-3. To induce experimental colitis, 200 mg/kg dinitrobenzene sulfonic acid (DNBS) + 30% ethanol combination was rectally administered to anesthetized mice. Total oxidant (TOS) and total antioxidant (TAS) levels were measured at the tissue level. Results: Lower concentrations of TOS were observed in the probiotics groups (2.11 +/- 0.23 mmol H2O2 Eq/L), probiotics+omega-3 (2.56 +/- 1.18 mmol H2O2 Eq/L), and omega-3 (3.02 +/- 1.88 mmol H2O2 Eq/L) groups compared to the colitis group (3.11 +/- 0.91 mmol H2O2 Eq/L) (p>0.05). Higher TOS and TAS level were observed in the control colitis group compared to other groups; however, the differences were not statistically significant. Conclusion: Our findings showed that TAS and TOS levels were positively affected by the use of probiotic supplements in IBD. It was determined that using w-3 alone was ineffective in decreasing TOS levels. Studies with higher dosages and longer treatment periods are needed to better observe the effects of nutritional supplements on TOS and TAS parameters in inflammatory bowel diseases.Item Effects of Nutritional Knowledge of Informal Caregivers on Depression and Metabolic Outcomes of Hemodialysis Patients(2021) Kiziltan, Gul; Turker, Perim Fatma; Beyaz, Esra Koseler; Saka, Mendane; Sayin, Cihat Burak; 0000-0001-8287-6572; 34459351; J-3707-2015Chronic renal failure (CRF) makes significant changes in the life of patients and their families. A good family support has a positive effect on successful patients' adaptation to the treatment and compliance with dietary regimen. This study aimed to examine the effects of nutritional knowledge of informal caregivers on depression and metabolic outcomes of hemodialysis patients. This was a cross-sectional study conducted at Baskent University Hemodialysis Center with 116 hemodialysis patients and their informal caregivers. Findings revealed that the caregivers who were the couple of the patients had the highest nutritional knowledge level than the other caregivers (p < .05). The postgraduate caregivers were more likely to have high nutritional knowledge level than the others (p < .05). The inflammation marker of the patients was significantly lower in the group of caregivers with higher level (T3 group) of nutritional knowledge than the others (p < .05). The mean CES-D scores were also more likely to be low in T3 group than in the others (p < .05). These findings highlight that the nutritional knowledge of caregivers of hemodialysis patients may have an additional benefit on patients' nutritional management and metabolic outcomes.Item Association of the Relationship Between Nutritional Status and Certain Biochemical Parameters in Obese Children(2021) Ozcelik-Ersu, Dilek; Kiziltan, GulThe prevalence of childhood obesity is increasing globally. Adiposity is more concentrated in subcutaneous tissue in women and visceral fat tissue in men. Abdominal obesity is more commonly associated with metabolic diseases in men. The results showed that the mean BMIz scores of boys was higher than girls, but total body fat was lower than girls. Total body fat free mass, water and muscle mass were higher in boys than girls. It was determined that children aged 10-17 years consumed fatty and sugary snacks and sugary drinks at school. Food consumption containing the carbohydrate, fat, saturated fat and cholesterol were higher in boys than girls. As a result, it was thought that it would be more beneficial and reliable to use anthropometric methods showing body composition together with BMI zscore while evaluating body weight in adolescents. While nutritional counseling, it may be beneficial to consider that the energy and nutrient requirements of male adolescent individuals and their daily food consumption are higher than girls. When the results of the study are evaluated, we mention that it would be appropriate to evaluate girls more carefully in terms of iron deficiency anemia and diseases such as insulin resistance and diabetes.Item Combined Therapy with Probiotic VSL#3 and Omega-3 Fatty Acids Attenuates Colonic Injury and Inflammation in Chronic DNBS-induced Colitis in Mice(2021) Ilktac, Havvanur Yoldas; Kiziltan, Gul; Lanpir, Asli Devrim; Ozansoy, Mehmet; Gunal, Mehmet Y.; Togay, Sine Ozmen; Keskin, Ilknur; Ozdemir, Ekrem M.; Kilic, UlkanInflammatory bowel disease (IBD) is a progressive chronic inflammatory disease affecting the gastrointestinal tract with a chronic relapsing and remitting disease course. While there are a number of therapeutic strategies available to treat IBD, a definitive treatment still hasn't been defined, leading to alternative treatment options including nutritional support. Herein, we planned to investigate the combined impact of probiotics and omega-3 (omega-3) fatty acids on inflammatory response and intestinal epithelium in chronic colitis induced by 2,4-Dinitrobenzenesulfonic acid (DNBS). Fifty BALB/c mice were randomly divided into five groups: non-colitis control, colitis with no treatment applied (control colitis), colitis treated with probiotics (VSL#3), colitis treated with omega-3, and colitis treated with both VSL#3 and omega-3. Colitis was induced by intrarectal administration of 2,4-Dinitrobenzenesulfonic acid (DNBS) in all groups but the non-colitis control group. Ten days after the DNBS period, phosphate-buffered saline (for both the non-colitis control and colitis control groups), VSL#3, omega-3, or VSL#3 + omega-3 treatments were administered intragastrically to their respective groups for 10 days. By analyzing the colonic expression of interleukin IL-6, IL-10, and IL-17A, and interferon gamma (IFN-gamma) and tumor necrosis factor alpha (TNF-alpha) levels, results revealed that levels of IFN-gamma IL-17, and TNF-alpha were significantly higher in the control colitis group when compared with the other groups. The control colitis, colitis +VSL#3, and colitis + omega-3 groups exhibited higher scores of microscopic damage compared to the non-colitis control and colitis + VSL#3 + omega-3 groups. The closest histological image to the non-colitis control group was presented in the colitis + VSL#3 + omega-3 group. The findings indicate that the combined effect of probiotics and omega-3 fatty acids might have a protective effect against colon injury and inflammation by creating synergistic effects. However, more research is needed to understand the exact mechanism of this synergistic effect and to examine how this therapeutic approach can be used in inflammatory bowel diseases.Item Challenges and needs of informal caregivers in elderly care: Qualitative research in four European countries, the TRACE project(2020) Akgun-Citak, Ebru; Attepe-Ozden, Seda; Kav, Sultan; Acar, Sema; Aksoydan, Emine; Altintas, Atahan; Aytar, Aydan; Baskici, Cigdem; Kiziltan, Gul; 0000-0003-0361-7498; 0000-0002-0484-4687; 31756568; V-9745-2019; ABD-7108-2020Background: Providing informal care may affects caregivers' life in different ways. Determining the needs of caregivers and supporting them can improve both the quality of life of the caregivers, as well as the elderly they take care of. Objective: To explore the experiences and needs of the informal caregivers in four countries. Design: Qualitative research method was used in the study. Methods: The qualitative data was collected through focus groups and individual interviews between December 2016-May 2017. In all countries interviews were conducted in the mother language of the informants. Informants of the qualitative research were adult people who take primary care of an individual with chronic diseases, aged 65 years or older. Data were collected from 72 informal caregivers from four European countries. Inductive content analysis was performed. Results: Informal caregivers identified 2 themes, 5 subthemes, 19 categories and 7 subtcategories. The themes highlighted two major issues: informal caregiver's challenges and needs related to the management of care of elderly and caregivers' personal needs. Conclusion: The important and charming results of the present study are, difficulties of managing caregiver's own life, and coping with emotions are common in four countries. Identifying challenges and needs of informal caregivers enable healthcare professionals to develop care strategies and plan interventions focused to support and help to reduce the burden of care for elderly with chronic diseases.Item Effect of adherence to carbohydrate counting on metabolic control in children and adolescents with type 1 diabetes mellitus(2020) Bayram, Sinem; Kiziltan, Gul; Akin, Onur; 0000-0003-1569-7747; 32871653Purpose: Carbohydrate counting provides better glycemic control and flexibility than other food planning methods. Consistent adherence to such a complex method is difficult, especially for youth. However, studies that determine adherence to this method and whether it alters metabolic control are limited. The aim of the current study was to determine adherence to this method and investigate its effect on metabolic control, anthropometric measurements, insulin dose, and energy intake. Methods: In this prospective cross-sectional study, 53 children and adolescents with type 1 diabetes mellitus aged 2 to18 years and receiving intensive insulin therapy were trained and followed for 6 months. Demographics, anthropometrics, insulin requirements, hemoglobin A1c (HbA1c), fasting lipids, and food records at baseline and study conclusion were evaluated. At the end of the study patients were divided into adherer and nonadherer groups according to carbohydrate estimate deviations from standardized daily sample menus and calculations for accurate insulin doses. More than 10-g variation in daily consumed carbohydrate amount or failure to decide bolus insulin dose was defined as a nonadherer. Results: The mean HbA1c, low-density lipoprotein cholesterol, and body mass index standard deviation score changed after the carbohydrate counting training while the mean HbA1c between groups was significant (P<0.05). Total daily insulin doses increased, and the mean high-density lipoprotein cholesterol levels decreased in both groups. There were significant correlations between HbA1c and carbohydrate deviation scores as well as HbA1c and caregiver's education level. Conclusion: Since adherence to carbohydrate counting may affect metabolic control, health professionals should evaluate and monitor carbohydrate counting skills of caregivers and patients in order to improve efficiency.
