  • Influence of physical activity and nutrition on sleep quality of Romanian
           students: a case study

    • Authors: Octavian Barna, Alina Plesea-Condratovici, Antonela Oltean, Raducu Popescu, Diana Victoria Gidu, Daniel Duta, Ioan Turcu, Dan Circiumaru, Cristina Varzaru
      Abstract: Sleep problems are associated with poorer quality of life, as well as mental and physical health issues, especially in people who are overweight or obese. Numerous studies have shown that there is a link between sleep and diet and between sleep and physical activity (PA). The present study aimed to show the connection between physical activity, diet, and the quality and duration of sleep in Romanian students. The main study was conducted on 876 students (435 women and 441 men) aged 19–26. Three weeks after the start of the main study, a subset of 83 male and female students aged 19–25 years were randomly selected to participate in an ancillary study. A questionnaire survey was conducted in order to determine the quality of sleep (PSQI), nutritional habits (HEI Index 2005), and physical activity (IPAQ), while anthropometric measurements were performed to determine body mass index (BMI). For students involved in the main study, PSQI varied between 6.4(2.3) and 4.5(1.7) and PA from 409.15(108.12) to 5834.54(2548.32) MET. The number of hours of sleep varied between 6.8(2.2) and 7.6(1.8). The HEI index varied between 52.1(12.2) and 55.3(11.4), being directly proportional to the increase in sleep quality and the number of daily sleep hours. Similar results were obtained for the ancillary study. Statistical analyses were performed using SPSS version 23 (SPSS, Inc. Chicago, IL); a value of 5% was set as the conventional significance level. ANOVA was used to identify statistically significant differences between averages of variables for the groups. For all variables analyzed, t tests showed no significant differences between females and males as p > α = 0.05 and the 95% confidence interval contained the value 0.

  • Fatty acid compositions of Zea mays L. varieties in Turkey

    • Authors: Cengiz Yrürdurmaz, Hasan Yildiz
      Abstract: Physical and chemical characteristics of oils are determined by the rate and composition of the fatty acids they have. Knowing the fatty acid composition of oils will enable the production of oils according to intended usage areas. The present study was conducted to determine the fatty acid composition of 20 different corn varieties grown in Turkey. The oil contents of the samples were determined with the Soxhelet Oil Extraction Device, and the fatty acid composition was determined with the GC-S/FID Device. The dominant fatty acids of the cultivars and lines that were examined in the scope of the present study were found to be linoleic acid (50.05-53.14%), oleic acid (31.09-33.21%), palmitic acid (11.07-13.16%), stearic acid (2.10-2.55%), linolenic acid (0.55-1.18%), and arachidic acid (0.36% - 0.53%). It was found that the differences between cultivars were very significant for all the characteristics studied here except for lauric acid. The findings of the study show that there is a wide variation in fatty acid composition in the existing cultivars and lines.

  • Validity and Reliability of the Turkish Version of the Adult Picky Eating

    • Authors: Feride Ayyıldız, Kübra Esin
      Abstract: Background and aim: Picky eating (PE) is generally expressed as a behavior seen in childhood, approximately one out of every three adults have been reported to exhibit PE behavior. Also, it is one of the determinant eating behaviors in the diagnosis of eating disorder-Avoidant/Restrictive Food Intake Disorder (ARFID). The aim of the present study was to translate, adapt and validate the Adult Picky Eating Questionnaire (APEQ) into Turkish. Methods: This study included 1135 adults (556 male, 579 female) with a mean age of 30.54 ± 11.73 (ranged from 18 to 63 years old). The APEQ was translated and adapted to Turkish according to the Beaton guideline. Eating Attitudes Test-Short Form (EAT-26) was used in the evaluation of eating behavior, and Kessler Psychological Distress Scale was used for psychological evaluation. Results: Items 2 and 3 were removed from the scale because total item correlation of these items was below 0.30. The Cronbach's alpha for the total scale of the APEQ-Tr was 0.731, with 0.630, 0.602, 0.627, and 0.671 for Meal presentation, Food variety, Meal disengagement and Taste aversion, respectively. APEQ-Tr, which is related to eating disturbance and psychological distress, showed an acceptable reliability with all its subscales. Conclusions: In conclusion, the Turkish version of APEQ (APEQ-Tr) can be used to evaluate PE in the Turkish population.

  • Relationship between food insecurity and diabetes among patients in Saudi

    • Authors: Mahitab Hanbazaza, Sami Alzahrani, Ghada Makki, Ghalia Almihmadi, Nawahil Mohammed
      Abstract: Background: Food insecurity (FI) is a major determinant of nutritional status, which could influence the self-care practices of diabetic patients. Objective: To assess the prevalence of FI and examine the relationship between FI and self-management practices among patients with diabetes. Methods: A cross-sectional survey was conducted on 229 patients at the diabetes clinic in King Abdulaziz University Hospital, Jeddah, Saudi Arabia. Results: The prevalence of FI was 26.2%, and it was more prevalent among non-Saudis, unemployed participants, and those with low household incomes (<5,000 SAR), as compared to food secure group (p <0.0001 for all comparisons). FI significantly predicted higher odds of irregular self-monitoring of blood glucose (OR = 2.47, 95% CI, 1.14–5.37, p = 0.022). Additionally, FI significantly predicted cost-related non-adherence to medication use (β = 1.95, 95% CI, 1.60–2.29, p <0.0001), and hypoglycemia-related complications (β = 0.69, 95% CI, 0.50–0.88, p <0.0001). These indicators were significantly influenced by severe FI. The intake of unhealthy food moderated the relationship of FI with hypoglycemia and its related complications (β = 0.11, 95% CI, 0.03–0.18, p = 0.006). Conclusions: Food assistance coverage and health awareness programs are required to support food insecure diabetic patients, a step that could optimize their healthy food choices and self-management practices.

  • Macronutrient intake and energy availability in young male elite cyclists:
           the importance of adequate CHO intake

    • Authors: Tadeja Jakus, Zala Jenko Pražnikar, Mihaela Jurdana
      Abstract: Aims: Macronutrient intake before, during and after exercise may influence performance and inflammatory responses in elite athletes. In this context, we analyze the adequacy of nutritional status, daily energy and macronutrient intake as well as intake during and after acute training, energy availability (EA) and inflammatory response after acute training associated with carbohydrate intake (CHO) in ten young male elite cyclists.  Methods: Ten Slovenian competitive cyclist, aged between 15 and 30 years participated in this study. Energy intake (EI) and macronutrient intake were assessed using 3-day dietary protocols.  Venous blood samples were collected before and after acute exercise to analyse serum biochemical parameters, as well as pro-inflammatory (CRP, IL-6 and TNF-α) and anti-inflammatory (adiponectin) cytokines. Results: The average macronutrient composition of daily EI was 6.1 g/kg body mass (BM) of CHO, 1.7 g/kg BM of protein, and 29% EI fat, and in most cases did not meet exercise intensity recommendations. Less than 50% of all participants consumed sufficient CHO daily and during exercise (mean intake was 6.1 g/kg BM and 32g/h, respectively). Protein intake was the only category in which most participants (70%) met the recommended daily amounts (1.7 g/kg BM) and the amounts during and after exercise (0.08 g/kg BM and 0.5 g/kg BM). Fat intake during (15% EI meal) and immediately after exercise (32% EI meal) exceeded the recommended amount and less than 40% of all participants adhered. EI was below estimated requirements (45 kcal/kg BM) and most of our participants had subclinical EA (35 kcal/kg FFM). We observed a positive correlation between daily CHO and EA (p=0.024) and serum ferritin (p=0.014). Finally, adequate CHO intake during and after exercise reduces pro-inflammatory IL -6. Conclusion: Young male elite cyclists did not meet energy demands and specific macronutrient requirements. Inadequate carbohydrate intake, low EA, and ferritin concentrations may exacerbate inflammation after acute exercise. These findings may have both short- and long-term implications for the health and performance of young cyclists.

  • Association of Type 2 Diabetes Risk with Some Anthropometric Measurements
           in Obese Adults

    • Authors: Nazal Bardak Perçinci
      Abstract: Type 2 diabetes can be defined as an insidious disease that can last for years without symptoms. Disease In type 2 diabetes, insulin resistance and insulin secretion deformation are predominant and account for about 90-95% of all diabetics (5). The major disadvantage of delayed diagnosis is the increased risk of complications. The management of risk factors and risk factors that can be considered as a finding can prevent the disease or keep it uncomplicated (6). A total of 95 obese women adults with a mean age of 33.65 ± 1.62 years were included in this study. All cases were women. The Finnish Type-2 DM Risk Scale (FINRISK) was used to determine the risk of type 2 diabetes. FINDRISK (diabetes risks) scoring results of the participants are given in Table 2. According to this distribution, 15.8% of the participants were low risk, 26.3% were mild risk, 28.4% were medium risk, 13.7% were high risk and 15.8% were carries a very high risk. When body weight and risk scoring were evaluated, body weight was found to be statistically significant between the low-risk group and the high-risk group and the low-risk group and the medium-risk groups (<0.001). The difference between BMI values ​​between low risk group and medium risk group, low risk group and mild risk group and between high risk and very high risk groups were found to be statistically significant (<0.001). No statistical significance was found between height and body fat percentage (%) values. The difference between waist circumference, hip circumference and waist / hip ratio values ​​between low risk group and medium risk group, between low risk group and high risk group, and between mild risk and high risk groups were statistically significant (<0.001).

  • Determination of Preoperative and Postoperative Serum Leptin, Ghrelin,
           Insulin, and Irisin Hormone Levels in Left Abomasum Displacement

    • Authors: Hale Ergin Eğritağ, Tülay Büyükoğlu, Kürşad Yiğitarslan
      Abstract: Background and aim: Left Displacement Abomasum (LDA) is a metabolic disorder associated with negative energy balance, especially in dairy cattle, and might cause economic losses. This study, it was aimed to evaluate the serum levels of insulin, leptin, ghrelin, and irisin hormones responsible for energy metabolism before and after the operation in Holstein cattle with LDA. Methods: For this purpose, cattle were divided into three groups (Group 1: Healthy, Group 2: Pre-operative, Group 3: Post-operative) with 8 animals in each group, and blood samples were collected. In serum samples, glucose, non-esterified fatty acid (NEFA), beta-hydroxybutyrate (BHBA), total protein, triglyceride, total cholesterol, and calcium levels were measured with an autoanalyzer. In addition, commercial kits measured serum insulin, leptin, ghrelin, and irisin hormone levels with the EIA method. Results: Preoperative serum glucose, NEFA, and BHBA levels were higher in cattle with LDA, and total protein and triglyceride levels were lower than in healthy animals (p<0.05). In cattle with LDA after the operation, these values ​​were similar to those of healthy animals. In hormone analysis, ghrelin, insulin, and irisin were found to be higher in animals with LDA, while leptin levels were found to be decreased (p<0.05). After the operation, the insulin levels of the cattle with LDA decreased below the pre-operative values; It was observed that leptin and irisin levels were increased (p<0.05). Conclusions: In cattle with LDA, increased ghrelin levels may be due to anorexic conditions; Increased insulin levels may be due to stress and negative energy balance. Decreased serum insulin levels in cattle after the operation suggested that it may be related to the insulin resistance state caused by the left displacement abomasum. Increased serum leptin can be considered an acute phase response to leptin, and an increase in serum irisin can be a marker of pain and stress.

  • Adiposity indicators, cardiometabolic parameters and critical size of
           adipocytes in premenopausal women

    • Authors: Biljana Srdic Galic, Edita Stokic, Aleksandra Korac, Mirjana Udicki, Aljosa Mandic
      Abstract: Background and aim: Adipocyte hypertrophy is an indicator of adipose tissue dysfunction that precedes the development of obesity comorbidities. The aim of this study was to analyze relationship between adiposity indicators, cardiometabolic parameters and the size of abdominal adipocytes in premenopausal women, and to develop cut-off levels for anthropometric indicators based on the critical size (100 μm) of visceral adipocytes. Methods: Study group consisted of 50 premenopausal women aged 42.88±7.17y. Subcutaneous and visceral (omental) adipose tissue samples were taken during laparotomy, and adipocyte size was analysed. Prior surgery all subjects underwent body composition analysis, anthropometric mesurements, and cardiometabolic risk assessment. Results: The size of subcutaneous and visceral adipocytes correlated significantly with all indicators of overall and regional adiposity, except thigh skinfold thickness, proximal and distal thigh circumferences. Indicators of upper body adiposity had better correlation with the size of visceral adipocytes comparing to subcutaneous adipocytes. Blood pressure and leptin levels had stronger correlation with the size of subcutaneous, while tryglicerides, HDL-cholesterol, uric acid, glycaemia and HOMA showed better correlation with the size of visceral adipocytes. After adjustment for overall and regional adiposity significant correlation only remained between subcutaneous adipocyte size and diastolic blood pressure (r=352, p<0.05) and visceral adipocyte size and glycaemia (r=0.346, p<0.05), while correlation between LDL-cholesterol and size of visceral adipocytes became significant (r=0.294, p<0.05). Among all anthropometric parameters highest predictive ability for critical size of visceral adipocytes showed waist-to-height ratio and body fat percent (AUC: 0.879 and 0.878, respectively). Specific cut-off values were obtained for following anthropometric parameters: waist-to-height ratio (0.51), body fat (39.65%), sagittal abdominal diameter-to-height ratio (0.16), waist-to-tight ratio (1.48), abdominal skinfold thickness (41.60 mm), abdominal diameter index (0.58), waist circumference (86.90 cm), waist-to-hip ratio (0.85), conicity index (1.19), trunk fat (34.00%), sagittal abdominal diameter (26.25 cm) and chest skinfold thickness (28.20 mm). Conclusions: These results imply to a fine interplay between cellular-to-whole body level morphology and functionality.

    • Authors: Pierantonio Bellini, Silvia Sabatini, Milena Nasi, Lucia Dall'olio, Luigi Generali, Daniela Mecugni, Ugo Consolo, Anna Vittoria Mattioli
      Abstract: Background: The recent coronavirus disease 2019 (COVID-19) pandemic has strongly affected the young population, with a significant impact on their habits. The present study aimed to explore the effects of COVID-19 on oral health and general hygiene habits in a cohort of undergraduate students during the lockdown period in march 2020. Methods: A total of 500 under-graduate students with a mean age of 22.84 ± 2.68 years completed an anonymous web survey. We compared 2 groups: students belonging to dentistry and dental hygiene school and students belonged to nursing school. Results: The 75 % of students self-reported an increased stress and 80% were concern about the future. A reduction in personal and dental hygiene (8% and 4%, respectively) was observed. Students in dentistry and dental hygiene courses were more careful about their dental hygiene. Interestingly, students from the dentistry and dental hygiene courses reported an increase in the use of chlorhexidine mouthwash during quarantine due both to an increased frequency of use and to a switch to chlorhexidine mouthwash from others type of mouthwash. This change was probably due to the knowledge of some studies that supported the efficacy of chlorhexidine mouthwash in fighting the COVID-19 infection Conclusion: Pandemic-related stress has affected our students’ population, with changes in general and dental hygiene habits. Strong action must be taken to promote good oral hygiene habits and a healthy lifestyle among the students’ population after the COVID-19 pandemic.

  • Mineral Contents and Fatty Acids Compositions of Fillets of Female and
           Male Pangas (Pangasıus Hypophthalmus, Sauvage 1878) Cultured in Turkey

    • Authors: Engin Artar, Mine Percin Olgunoglu, İlkan Ali Olgunoglu
      Abstract: Pangas (Pangasius hypophthalmus) is a food resource with great economical importance in Asian countries. This study provides baseline data on some macro and micro minerals and fatty acids composition in fillets of female and male Pangasius hypophthalmus cultured in Turkey. Among the minerals determined in both fillets samples, Na was found to be highest, followed by K, Mg and Ca. The order of average micro minerals concentrations was Fe>Zn>Cu>Mn in both fillet samples. In the research, statistically significant differences were not observed in all determined macro and micro minerals when compared to each other. The major fatty acids detected were C16:0, C18:0, C18:1(n-9) and C18:2 (n-6). The results revealed that fillets of male pangas are a better source of minerals, protein and fatty acids than fillets from female pangas.

  • Evaluation of The Association Between Obesity, Dietary Phytochemical
           Index, and Breast Cancer Risk and Knowledge Level

    • Authors: Gözde Çalışkan, Bartu Eren Güneşliol, Neslihan Sürmeli Akçadağ, Nilüfer Acar Tek
      Abstract: Abstract. Breast cancer is one of the most common cancers globally and has been reported as the leading cause of cancer-related death in women. Obesity is defined as one of the most important risk factors for breast cancer. Besides, oncological studies have reported that regular daily consumption of phytochemicals can reduce the risk of breast cancer. Therefore, this study aimed to clarify the association between obesity, dietary phytochemical index (DPI), breast cancer risk (BCR) and knowledge level (BCKL). Methods: This study was conducted with women aged 18 years and older. Participants filled out sociodemographic and lifestyle characteristics, anthropometric data, 24-hour retrospective food consumption records, BCR, and BCKL scales via Google forms. Body weight, height, and waist circumference (WC) were declared by the participants. BMI, waist to height ratio (WtHr), DPI, BCR and BCKL calculations were made by the researchers. Results: In terms of BCR, 94.2% of the participants were in the low, 3.3% in the medium, 0.3% in the high, and 2.2% in the highest risk group. Besides, there were significant differences between body weight, height, BMI, WC, and WtHr values of BCR groups. Yet, no significant difference was observed between the DPI of BCR groups. Moreover, DPI was not associated with BMI, WC, BCR, and BCKL. However, BMI was significantly correlated (moderate-to-strong) with WC and BCR (r=0.719 and r=0.605, respectively). Also, WC was significantly correlated (moderate) with BCR (r=0.475). The association between WC and BCKL (r=0.088) was statistically significant but not clinically. Conclusion: In conclusion, although BCR was not associated with DPI, it was associated with BMI and WC values, which are the indicators of obesity. In the light of this information, the associations between obesity, DPI, BCR, and BCKL will be understood more clearly in future studies with a large sample in which BCR groups have an equal distribution.

    • Authors: Ülkü Demirci, Ayşegül Kaptanoğlu
      Abstract: Background and aim: In individuals working in shifts, the risk of metabolic disorders and diseases is amplified due to irregular timing of the meal, quality of nourishment received from the diet, and inadequate sleep. In this survey, we studied the nutritional status and quality of life (QoL) among shift workers and the factors affecting these characteristics. Methods: An online survey was conducted among 137 adult participants working in shifts in the Beylikdüzü campus. The data were collected using the QoL assessment tool EQ-5D-5L questionnaire. Results: The mean score of EQ-5D-5L sub-dimensions, mobility (1.27±0.56); self-care (1.12±0.51); usual activity (1.14±0.42); pain-discomfort (1.43±0.69), and anxiety-depression (1.66±0.87) were low. In 48(35.8%) participants shift time deviated their mealtime. A total of 74 (54%) participants ate 2 meals during the day shift while 78(56%) ate 1 meal during the night shift. Conclusions: Working in shifts had a negative effect on mealtimes, nutrition, and meal frequency.

      Abstract: Study Objectives: This study aimed to compare oxidative stress levels and enzyme activities in biathlon skiers and sedentary athletes. Methods: A total of 30 participants, 15 biathlon athletes, and 15 sedentary athletes, were included in the study. The athletes were not subjected to a training program but were asked to refrain from eating or drinking after 10:00 PM the day before the samples were taken. Blood samples were taken from the participants after they were informed about the tests. SOD, CAT, and GPx enzyme activities, which are among the lipid peroxidation products, MDA, and antioxidant enzymes, were evaluated spectrophotometrically. Results: It was showed that SOD (p˂0.001), CAT (p˂0.01), and GPx (p˂0.001) enzyme activities were higher in the biathlon athletes compared to those of the sedentary athletes and that the level of MDA, an important lipid peroxidation product, was lower in the biathlon group than in the sedentary group (p˂0.001). Conclusion: As a result, SOD, CAT, and GPx enzyme activities, which are among the lipid peroxidation products of MDA and antioxidant enzymes, were evaluated spectrophotometrically. It was determined that MDA level, which is among the important lipid peroxidation products, decreased in the biathlon group and that SOD, CAT, and GPx enzyme activities were increased in the biathlon group compared to the sedentary group.

  • Association between low serum folic acid and vitamin B12 levels with
           COVID-19 prognosis

    • Authors: Olgun Keskin , Ayşegül Seremet Keskin , Nilgün Seremet
      Abstract: Background and aim: It is important that the immune system is active and strong in protection from the COVID-19 pandemic. Folic acid and vitamin B12 involved in the initiation, maintenance and regulation of both innate and adaptive immune reactions of the host against the infections. In this study, it was aimed to investigate the relationship between serum folic acid and vitamin B12 levels of COVID-19 patients on the prognosis of the disease. Methods: The sample of the study consists of 529 individuals hospitalized in the Pandemic Chest Diseases Intensive Care Unit. General characteristics of the individuals, biochemical parameters checked routinely (white blood cell (WBC), platelet (PLT), lymphocyte, Neutrophil/Lymphocyte (N/L) rate, C-reactive protein (CRP), oxygen (O2) saturation at the time of admission), serum vitamin B12 and folic acid levels, length of stay in intensive care unit (ICU) and hospitalization, and mortality were recorded.   Results: The mean age of individuals was 62.8±15.12 years, and 50.9% were men and 49.1% women. The mean level of serum folic acid in the subjects was 9.1±4.91 (ng/mL), and 2.4% had folic acid deficiency and 28.4% had folic acid insufficiency. The mean serum vitamin B12 was 295.6±229.98 (pg/mL), and vitamin B12 deficiency was observed only in 14.4%. The increase in serum folic acid levels reduces the total length of hospitalization and the risk of mortality (p<0.05). On the other hand, no correlation was found between B12 levels and the length of stay in ICU, hospitalization and mortality. It was shown that WBC and N/L rate decreased as serum folic acid levels increased, and O2 saturation at the first hospital admission was higher. Conclusions: Folate deficiency and insufficiency are common among hospitalized COVID-19 patients and cause progression to severe disease. Therefore, examining COVID-19 patients in terms of nutritional deficiencies is critical in monitoring the clinical outcomes of  disease

  • The Consumption of Dietary Supplements among Gym Members in Amman, Jordan

    • Authors: Mai Abu Yaman, Mohammed Omar
      Abstract: Background: Dietary supplements (DS) are considered as a major part of many athletes’ life. Objective: The aim of the study was to determine the prevalence of DS use among gym members in Amman, Jordan. Moreover, to determine their sources of information about DS, and assess their level of knowledge regarding the use of DS. Methods: A cross-sectional study was conducted using validated questionnaire among 397 gym members in the city of Amman, Jordan. The questionnaire included demographic data, use of DS, sources of information of DS, and personal knowledge and attitudes about DS. Results: The results of the study indicated that (146 participants, 36.8%) of participants were between 24–29 years old and that the prevalence of DS use was (70.8%) of the participants. Most of the study participants were found to obtain their information from sport coaches (37.4%), followed by nutritionist (24.2%) and health staffs (11.1%). Proteins were found to be the most single type of DS used through the users of DS (21.4 %), followed by vitamins (14.0 %). Pearson chi-square statistics revealed that gender was the only variable that make significant difference (p<0.05) regarding the type of DS and the source of information among users of DS. About two-third of the users of DS had sufficient information or knowledge regarding their supplements and nearly the same percentage pay attention to the nutrition facts of these supplements. Statistical analysis program SPSS (version 21) was used and statistical significance set at p-value <0.05. Conclusion: A large proportion of gym members in Amman use DS with a high percentage of proteins and vitamins among the most used DS. Coaches and nutritionists play a key role in counseling gym members about appropriate DS. Actually, gym members need more education programs to increase the percentage of members with high knowledge regarding DS.

  • Effect of Omega-3 fatty acid added to parenteral nutrition on inflammatory
           in preterm infants

    • Authors: Guzin Tumer, Seyit Mehmet Mercanlıgil, Canan Aygun Seren, Ayhan Dağ
      Abstract: Objective: This study aimed to investigate the effect of omega-3 fatty acid addition to Total Parenteral Nutrition (TPN) on the inflammatory process and clinical outcomes. Methods: The study included 51 infants who were in the Neonatal Intensive Care Unit (NICU) and fed by TPN for minimum 10 days, with a gestational age of ≤32 weeks and a birth weight of ≤2500 g. The preterm infants fed by TPN with 80% omega-9 and 20% omega-6 fatty acids were determined as Group 1(n:26) and by TPN with added omega-3 fatty acid (1.0g/day) as Group 2 (n:25). This retrospective study retrieved demographic characteristics, anthropometric measurements, nutrition therapy details, comorbidity development, inflammatory markers, and laboratory and clinical results from patient files. Those who received exchange transfusions and who received TPN for less than 10 days were excluded from the study. Results: Comorbidity developed in 35% of Group 1 and 28% of Group 2, with no difference between the groups (p < 0.05). There was no difference in gestational week at birth, birth weight, duration of mechanical ventilation (MV), duration of oxygen support, and
      maternal age between the two groups (p < 0.05). There was no difference in the carbohydrate (CH), protein and lipid levels, and glucose infusion rate (GIH) between the two groups (p <0.05). In Group 2, the daily amount of omega-3 fatty acid was increased by 1.0±0.1 g/day, accounting for 7.7±0.03% of the total energy. There was a significant decrease in the blood levels of Aspartate Aminotransferase (AST) and Total Bilirubin (T.Bil) on day 10 ​​in Group 2 (p < 0.05). Procalcitonin (PCT) significantly decreased on days 1, 4, 7, and 10 in both groups (p < 0.05). The difference in C-Reactive Protein (CRP) on days 4 and 10, and PCT and Neutrophil-to-Lymphocyte Ratio (NLR) on days 1, 4, 7, 10 was insignificant, with lower values in Group 2. Conclusion: The present study established a low level of positive changes in inflammatory findings and a decrease in liver function test results with the addition of fish oil to TPN. The different fatty acid contents of ILEs, the optimum ratio between the fatty acids, and the amount and duration of use affect the clinical outcomes. Further studies are needed to determine a safe, adequate dose and appropriate fatty acid profile.

  • Application effect of NRS2002 scale in perioperative nutritional
           intervention of patients undergoing radical cystectomy

    • Authors: Yibo Cai, Jinhan Lou
      Abstract: Objective: This study aimed to explore the effect of nutritional intervention based on the NRS2002 scale in perioperative nutritional intervention in radical cystectomy for bladder cancer. Methods: A total of 65 patients with bladder cancer who were treated in our hospital from January 2019 to January 2020 and who met the inclusion and exclusion criteria were enrolled as the subjects. These patients were randomly divided into a control group and an experimental group. The patients in the control group received routine perioperative nutritional intervention, and the patients in the experimental group were given nutrition intervention based on NRS2002. The quality of life, nursing satisfaction rate, nutritional indexes (serum albumin, transferrin, and prealbumin), and body mass index (BMI) before and after intervention were compared between the two groups. Results: The differences in nursing satisfaction rate, sleep, appetite, interpersonal communication, daily activities, and mental state scores between the two groups were statistically significant (P < 0.05). The levels of prealbumin, transferrin, albumin, and BMI in the experimental group were higher than those in the control group, and the differences were statistically significant (P < 0.05). Conclusion: The perioperative nutritional intervention based on NRS2002 for patients undergoing total cystectomy can not only significantly improve the perioperative nutritional level and BMI but also improve the quality of life and nursing satisfaction. This is worthy of clinical popularization.

  • Investigation of Antioxidant Activities of Melissa officinalis and
           Lavandula angustifolia Extracts against Chromium Induced Oxidative Damage
           in Saccharomyces cerevisiae with Molecular Biological and Biochemical

    • Authors: Seda Beyaz
      Abstract: Melissa and Lavandula are known to exhibit high antioxidant and strong biological activities thanks to their rich polyphenol and aromatic content. In this study, eight groups were created to investigate whether Melissa and Lavandula have a protective role against chromium damage in Saccharomyces cerevisiae (S. cerevisiae). Application groups: (i) Control Group; (ii) Chromium (30 mM); (iii) Melissa (20%); (iv) Lavandula (20%); (v) Melissa (20%) + Lavandula (20%); (vi) Melissa (20%) + Chromium (30 mM); (vii) Lavandula (20%) + Chromium (30 mM); (viii) Melissa (20%) + Lavandula (20%) + Chromium (30 mM). S. cerevisiae cultures were grown at 30 °C for 1, 3, 5 and 24 hours. Cell growth, malondialdehyde (MDA) analyzes, glutathione (GSH) levels, catalase (CAT) activities were determined by spectrophotometer. Total protein concentrations were determined by sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) and bradford method. According to the results, when compared with the chromium group, cell growth (1, 3, 5 and 24 hours), total protein synthesis, GSH level (24 hours) and CAT level (24 hours) increased in Melissa, Lavandula and Melissa + Lavandula while MDA level (24 hours) decreased. Melissa and Lavandula plant extracts, which are rich in polyphenolic compounds, were found to provide antioxidant protection and reduce oxidative damage in S. cerevisiae culture. Thus, it is thought that it will contribute to new treatment methodologies by providing effective protection in the treatment of many diseases thanks to its strong antioxidant and antiinflammatory properties.

      Abstract: The problem of drug-resistance developed by bacteria against antibiotics turned the attention of researchers to find out and develop such products which haven’t such issues. For this purpose, this study was carried out by using walnut and olive oil against several gram negative and gram-positive bacteria. Different concentrations of oils were employed using disc diffusion method. They exhibited better antibacterial properties. All the tested bacteria, viz. Citrobacter freundii, Enterobacter aerogenes, Escherichia coli, Klebsiella pneumoniae, Proteus vulgaris, Pseudomonas aeruginosa, Salmonella typhi, Salmonella typhimurium, and Shigella sonnei were considered susceptible to certain concentrations of both walnut and olive oil. High bacterial activity (18.9±0.7 mm) of walnut oil was observed against Salmonella typhi, 17±1.2 mm against Proteus vulgaris, 16.90±1.5 mm against Citrobacter freundii, 15±0.8 mm against Pseudomonas aeruginosa, and 14±1.3 mm against Klebsiella pneumoniae, while average activity was 13±1.2 mm against Salmonella typhimurium, 12.90±1.5 mm against Enterobacter aerogenes, 12±1.5 mm against Escherichia coli and 12±1.00 mm against Shigella sonnei.  Similarly, olive oil had its maximum antibacterial activity 26±1.5 mm, 23.1±1.00 mm, 19±1.5 mm, 19±1.5 mm, 19±0.8 mm, 18±1.1 mm, 18±1.5 mm, 15±1.00 mm, 15±0.7 mm, 14±1.1 mm against Enterobacter aerogenes, Salmonella typhi, Citrobacter freundii, Escherichia coli, Shigella sonnei, Klebsiella pneumoniae, Proteus vulgaris and Pseudomonas aeruginosa, respectively, whereas, optimum activity of olive oil was recorded against Salmonella typhimurium (13.15±1.0 mm). These findings showed that walnut and olive oils have a substantial effect on bacteria and can be used as effective antibacterial agents in the development of medicines.

  • A detailed comparison of the use of dietary supplements before and during
           the COVID-19 pandemic

    • Authors: Yonca Sevim
      Abstract: Background and aim: Considering the coronavirus disease 2019 (COVID-19) pandemic and the expectation that dietary supplements (DS) boost the immune system of individuals, the aim of this research was to evaluate the use of DS and related factors by comparing periods before and during the pandemic. Methods: A descriptive cross‑sectional internet-based study was conducted with 1488 participants from the general public aged above 19 years. Results: The median age of participants was 33.0 (19-69) years and 88% of participants were women. A total of 48.9% of participants (50.2% of females, 39.9% of males) used DS before COVID-19, and DS use during COVID-19 was reported to be 57.9% (58.6% of females, 52.8% males). Independent variables of DS use before and during COVID-19 were sex, age, body mass index (BMI), education, income, vitamin/mineral deficiency (VMD), alcohol use, and medication use. Participants who had no VMD used more DS, mostly herbal supplements such as grape seed, gotu kola, ginseng, ginkgo biloba and green tea. Vitamin D and C were the most commonly-used DS among participants with vitamin/mineral deficiency, followed by zinc and multivitamins. The main reason for DS use (47.2%) during COVID-19 was to strengthen immunity. Conclusions: The current findings may help to understand the preferences of individuals about DS use during pandemics. Understanding factors associated with the use of DS and their claimed immune-boosting effects may support future studies aiming to provide accurate information and motivate individuals towards healthy use of supplements during pandemics.

           Obese Women Who Follow a Weight-Loss Diet

    • Authors: Yeşim İşgüzar Orak, Sıdıka Bulduk, Mehmet Baştemir
      Abstract: Background and aim: This study was conducted to determine the effect of 8-week probiotic use on body composition and blood parameters in overweight and obese women who are on a weight loss diet Methods: 34 women with a BMI value above 25 kg/m2 participated. The individuals participating in the research were divided into two groups. For eight weeks, the experimental group was given a weight loss diet program, exercise program and oral probiotic nutritional supplement containing various probiotic strains in the amount of 1.5x109 cfu/g in each capsule twice a day; The control group was given a weight loss diet program and an exercise program without probiotic supplementation. Anthropometric measurements of the individuals (height baseline, body weight, waist, hip and neck circumference, body mass index, waist/hip circumference and waist-height ratio) in both groups were evaluated statistically at the initial, 4th and 8th weeks. Some biochemical parameters were measured at the beginning of the study and the end of the 8th week. Results: A significant difference was found between body weight, body mass index, waist circumference, hip circumference, waist-height ratio, body fat percentage, and body fat mass measurements (p<0,001). Significant improvements were found in LDL-C, fasting insulin, AST and TSH values in both groups (p<0.05). While the HOMA-IR values were significantly lower, HDL-C values were found to be significantly higher at the end of the study in the experimental group (p<0.05). Conclusions: Balanced hypocaloric diet caused significant improvements in anthropometric measurements and blood parameters in experimental and control groups. The use of probiotics has positive effects on HOMA-IR and HDL-C values in the experimental group.

    • Authors: Calin Avram, Laura Avram, Victoria Rus, Ion Mihai Georgescu, Florina Ruta, Peter Olah
      Abstract: Introduction. Food labels are very important when choosing healthy foods. Another important element that is found on the food label are alimentary additives that are added to the food to increase the shelf life or taste. Aim. The aim of our study is to identify how respondents understand and are aware of the information found on food labels. It is very important to be able to choose products that meet the consumers’ needs and that do not affect their health. Methods. In order to carry out this pilot study, cross-sectional descriptive, an online evaluation questionnaire was developed and disseminated between December 2016 and February 2017. Results. Out of the total of 476 participants in the study, the persons with higher or higher education represent over 80% of the respondents. Women are the most representative in this study almost 80% as well as people in urban areas. We can identify the association between the age of the participants and their residence (p = 0.0038), the education of the participants (p <0.001), the people who decide upon the products purchased (p = 0.039), reading the labels before purchasing (p <0.001). Conclusions. According to our study, the perception of information on food labels is very low. Information on the elements that allow the correct choice for buyers, both about food additives and about nutritional values could be beneficial for the health of the buyer.

           poor: the 60-year experience of the “Opera di San Francesco” in Milan,

    • Authors: Claudio Maioli, Fulvio Muzio, Federico Cioni, Marisa Porrini, Giuditta Maioli, Patrizia Riso
      Abstract: The rapid increase in the number of vulnerable people who depends on meals provided by the canteens for the poor all over the world suggests the importance to provide adequate menus 
      Objectives: to present a dining experience for the poor and/or homeless in Milan by analyzing: 1) the general characteristics of the canteen users 2) the nutritional composition of the meals with the aim of highlighting possible nutritional deficiencies 3) the feasibility aspects associated to the menu development and management
      Setting: Canteen for the poor “Opera di San Francesco” Milan, Italy
      Methods: A qualitative and quantitative analysis of the cost, type of foods and nutrients composition of the overall meals provided (736.352) was made and data compared with the reference values ​​for the adult Italian population (LARN 2014). The canteen distributes about 2,336 meals a day, 6 days a week from Monday to Saturday. The menus analysed were those of the winter (7 months, from 01/01 to 30/4 and from 01/10 to 31/12) and summer (5 months, from 1/5 to 30/09) seasons. The total number of meals in the period 2017-2020 was also considered.
      Results: On average, the winter menu provided 2039 Kcal as a mean (15% proteins, 29% lipids, 56% carbohydrates) while the summer menu provided 2146 Kcal (15% proteins, 28% lipids, 57% carbohydrates). The total number of meals provided remained constant in the period 2017-2020 despite the sanitary situation.
      Discussion: Overall, energy intake and macronutrients composition of both the summer and the winter menus were in line with recommendations. However, calcium, vitamin D, folate, vitamin B2, B6, B12 and zinc requirements were not satisfied due to the scarcity of foods such as milk and dairy products but also fish and vegetables while the salt content was high with respect to recommendations.

    • Authors: Lamia Ghomari, Hanane Ghomari-Boukhatem, Mourad Raiah, Youcef Boukhari, Malika Bouchenak
      Abstract: Background: Unhealthy lifestyle behaviors are key elements for weight gain, leading to several chronic diseases. The aim of this study was to evaluate lifestyle, cardiometabolic and inflammation markers and their associations with body mass index (BMI) in children. Methods: Schoolchildren (n = 225; G/B = 109/116); aged 7–10 years were recruited. Waist circumference (WC), and BMI were determined. Daily energy intake (DEI), total energy expenditure (TEE), energy balance (EB), physical activity level (PAL), and quality diet using KidMed index were evaluated. Cardiometabolic and inflammatory markers were estimated. Results: Anthropometric classification showed that 62% of children were normal weight (NW), 19% overweight (OW), 9% obese (O), and 10% thin (T). Compared to NW, OW and O presented respectively higher WC (p<0.05; p<0.01), weight, DEI and EB (p<0.01; p<0.001), and lower PAL (p<0.01 ; p<0.001), TEE and KidMed score (p<0.05 ; p<0.01), while T presented lower weight, DEI, EB and KidMed score (p<0.05). Uric acid (UA) values were higher (p<0.05) in O, leptin, interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α) concentrations were higher (p<0.001), and adiponectin levels were lower (p<0.01), in both OW and O, whereas, leptin and TNF-α values were lower, and IL-6 levels were higher (p<0.001) in T. Significant associations between WC, DEI, KidMed, leptin, adiponectin, IL-6, TNF-α and BMI were observed. Conclusion: In response to unhealthy diet, excess energy intake, and sedentary; excessive fat mass is noted inducing inflammatory status in children. These findings highlight the necessity of oriented strategies to track obesity and related diseases.

  • A scale development study to measure knowledge levels of obesity
           prevention methods: Obesity Struggle Knowledge Scale

    • Authors: Çetin Altunal, Betül Borku Uysal, Mehmet Sami İslamoğlu
      Abstract: In this cross-sectional prospective study, it was aimed to develop a scale to measure the knowledge levels of individuals on obesity struggle methods. The study was conducted on a total of 422 participants, 285 (67.5%) women and 137 (32.5%) men, who applied to our clinic with weight complaints between June 2019 and March 2020. A survey including baseline characteristics and Obesity Struggle Knowledge Scale with 15 items was applied to participants. EFA results showed that all items in the scale had factor weights higher than 0.40 with acceptable range. Kaiser-Meyer-Olkin (KMO) level showed that sample is adequate for the Principle Component Analysis (KMO: 0.817). Three factors with five items for each factor were found as “Nutrition Knowledge”, “Physical Activity Knowledge”, and “Medical Support Knowledge”. CFA analysis results showed that the scale had good fit with EFA results (CMIN/DF: 3.355; AGFI: 0.921; CFI: 0.955; IFI: 0.955; RMSEA: 0.075). Medical support knowledge had the highest mean, followed by physical activity and nutrition knowledge. All factors had higher reliability values. There were positive correlations between total obesity knowledge score with nutrition knowledge (r=0.608; p<0.01), physical activity knowledge (r=0.399; p<0.01) and medical support knowledge (r=0.627; p<0.01). There was positive and significant correlation between nutrition knowledge and medical support knowledge (r=0.141; p<0.01). The scale may applied to large samples, it can be determined which group needs more information in studies such as public service advertisements and education to be carried out to struggle with obesity. By this way, it may be possible to use public resources more efficiently and to reach individuals more effectively in health.
