Therefore, we hypothesized that dietary acid load (DAL) increases disease activity and inflammation in PsA patients. Methods This study was conducted with 58 obese/overweight patients, aged 20-65 years. Dietary intake was assessed using a 3-consecutive-day 24-hour recall. The DAL was evaluated through the PRAL (potential renal acid load) and NEAP (net endogenous acid production) and divided into the low and high groups by their median values. The disease activity assessments, anthropometric measurements, dietary data and blood parameters of patients were recorded and compared at the low and high DAL groups. Results We observed that patients in the high NEAP and PRAL groups had worse PsA pattern scores (p<0.05). Also, PRAL and NEAP scores were positively associated with DAPSA, HAQ, and PSAID-12 scores. After adjusting age, sex, smoking, and BMI, 1 m...

We aimed to explore whether REE estimated by a bio-impedance (BIA) device or by the Harris-Benedict (HB) equation and TEE estimated by a BIA device may provide an alternative for IC and PAL measurements in HNC prior to surgery. Methods: REE was measured by IC (Cosmed k4b2). REE estimated by BIA (Bodystat1500) using the Brozek & Grande equation, and by adapted HB equation (Roza & Shizgal, 1984) were compared to measured REE. TEE estimated by BIA, i.e., from REE and reported physical activity was compared to measured TEE (REE by IC and daily PAL [MET equivalents] as measured by accelerometer [SWP3]). Agreement was explored with ICC (two-way mixed) and Bland Altman plots. ICC !0.80 was considered adequate, p-value <0.05 was considered significant. Results: A sample of 19 HNC patients (61.9±6.6 y; 63% male; stage 1: n¼5, stage 2: n¼9, stage 4: n¼5) were included. For REE, agreement between BIA and IC (ICC¼0.40, 95% CI: À0.06e0.72) and between HB and IC (ICC¼0.46, 95% CI: 0.02e0.75) was not adequate. Also for TEE, agreement between BIA and IC was not adequate (ICC¼0.14, 95% CI: À0.21e0.51). Bland-Altman plots for REE showed a mean difference of 35 kcal (p¼0.731, limits of agreement [LOA]: 989; À919 kcal) for BIA vs. IC, and À66 kcal (p¼0.525, LOA: 798; À929 kcal) for HB vs. IC. Mean difference of TEE for BIA vs. IC was 491 kcal (p¼0.02, LOA: 2146; À1164 kcal). Conclusions: In this sample of HNC patients, REE estimated by HB or BIA, and estimated TEE do not adequately agree with measured REE and TEE, respectively. Estimates of REE and TEE were widely distributed and estimated TEE overestimated measured TEE. Therefore, our results suggest that IC and accelerometer measurements cannot be replaced by BIA and HB estimates. Disclosure of interest: None declared.

Healthy men (n=16, age: 24±6 years, body mass: 78±16 kg, BMI: 24.7±4.1 kg•m-2 , body fat: 15±5%) volunteered. One metabolic equivalent (1-MET: 3.95±0.64 ml•kg-1 •min-1) was measured during supine rest. Responses during the 30-min walk (n=3: 4-MET; n=13: 5-MET) (speed: 5.7±0.7 km•hr-1) were measured at 7-10, 17-20 and 27-30 min and averaged over the time periods. For intake conditions (7-days and 14-days), 2 capsules of NZBC extract (600 mg containing 210 mg of anthocyanins) were taken with breakfast (14-day washout). The final 2 capsules were ingested 2-hr before the morning walk. Intake duration of NZBC extract had no effect on heart rate, minute ventilation, oxygen uptake, and carbon dioxide production. Fat oxidation was enhanced with 7-and 14-day intake by 11±19% and 17±26% (

We hypothesized that participants with higher self efficacy can lose more weight. Methods: This study was conducted among 30 premenopausal women, aged 20e50 years old and had body mass index (BMI) 30 kg/m 2. Each participant received a balanced meal plan according to their requirements through reduced energy intake. Weight, height and body composition were measured at baseline and every 2 weeks during the 8 weeks. To find out the self efficacy status of the participants Weight Efficacy Lifestyle Questionnaire (WEL test) was applied at baseline and at the end of 8 weeks. Lower WEL scores indicates better self efficacy. Participants were divided into groups according to their weight loss success (<5%, "lost less weight-LLW" or 5%, "lost more weight-LMW" of initial weight). Statistical analysis were performed using the IBM SPSS software version 23. Results: At baseline,women were 35,7±8,7 years with a mean of BMI 35,9±5,2 kg/m 2. Participants lost 5,6 kg ±2,2 kg or 6,5±3,1% and decreased from initial mean in weight 89,7±16,1 kg to 84,1±16,6 kg at the end of 8 weeks (p<0,001). This corresponded to a reduction in BMI (p<0,001). It was observed that the WEL scores of the participants decreased from 52,9±17,7 to 36,9±9,2 (p<0,001) in comparison with the initial and the last values. Furthermore when participants were divided into groups based on weight loss success LMW group demonstrated lower WEL scores meaning that better self efficacy (p<0,05). Conclusions: Our study showed that self efficacy plays an important role in the success of weight loss. Identifying the possible effects of self efficacy will be useful in the treatment of obesity. Furthermore there is a possibility that psychological support can positively affect weight loss in relationship with self efficacy. Disclosure of interest: None declared.

Çalışma Planı: Çalışmaya 18-24 yaş arasında gönüllü üniversite öğrencileri dâhil edilmiştir. Katılımcılara beş bölümden oluşan anket uygulanmıştır. Anketin birinci bölümünde sosyo-demografik özellikler sorgulanmış, ikinci bölümünde Hollanda Yeme Davranış Anketi (HYDA) uygulanmıştır. Anketin üçüncü ve dördüncü bölümünde 24 saatlik besin tüketim ve fiziksel aktivite kayıtları alınmıştır. Katılımcıların diyet kalitelerini belirleyebilmek için, besin tüketim kaydı esas alınarak sağlıklı yeme indeksi (SYİ) puanları hesaplanmıştır. Anketin son bölümünde ise araştırmacılar tarafından katılımcıların çeşitli antropometrik ölçümleri alınmıştır. Bulgular: Çalışmaya toplam 198 öğrenci katılmıştır. Katılımcıların, %13,1'i hafif şişman veya obez grubunda yer aldığı ve SYİ puanına göre %68,2'sinin (n=135) diyet kalitesinin yetersiz olduğu belirlenmiştir. SYİ ile antropometrik ölçümler arasında ilişki bulunmazken, HYDA puanlarının antropometrik ölçümleri önemli düzeyde etkilediği gösterilmiştir. Oluşturulan çoklu doğrusal regresyon modellerinde, yaş, cinsiyet, günlük enerji alımı ve fiziksel aktivite düzeyi gibi potansiyel karıştırıcı etmenler için düzeltme yapıldığında, toplam HYDA puanı ve duygusal yeme, kısıtlayıcı yeme alt boyutu puanları ile antropometrik ölçümler arasında pozitif ilişki bulunmuştur (p<0,05). Bununla birlikte, dışsal yeme alt boyutu puanı ile antropometrik ölçümler arasında istatistiksel açıdan önemli bir ilişki bulunmamıştır (p>0,05). Sonuç: Bu araştırmadan elde edilen sonuçlar, obezite gelişimi açısından riskli grup olan üniversite öğrencilerinde, duygusal yeme ve kısıtlayıcı yeme davranışının obezite için bir risk faktörü olabileceğini göstermektedir.

Research paper thumbnail of Total Dietary Antioxidant Intake Including Polyphenol Content: Is It Capable to Fight against Increased Oxidants within the Body of Ultra-Endurance Athletes?

However, the contribution of total dietary antioxidant capacity on exogenous antioxidant defense and exercise performance has commonly been disregarded. The aims of the present investigation were to examine (i) the effects of dietary total antioxidant intake on body antioxidant mechanisms, and (ii) an exhaustive exercise-induced oxidative damage in ultra-endurance athletes. The study included 24 ultra-marathon runners and long-distance triathletes (12 male and 12 female) who underwent an acute exhaustive exercise test (a cycle ergometer (45 min at 65% VO2max) immediately followed by a treadmill test (75% VO2max to exhaustion). Oxidative stress-related biomarkers (8-isoprostaglandin F2alpha (8-iso PGF2a), total oxidant status (TOS, total antioxidant status (TAS)) in plasma were collected before and after exercise. Oxidative stress index was calculated to assess the aspect of r...

However, the contribution of total dietary antioxidant capacity on exogenous antioxidant defense and exercise performance has commonly been disregarded. The aims of the present investigation were to examine (i) the effects of dietary total antioxidant intake on body antioxidant mechanisms, and (ii) an exhaustive exercise-induced oxidative damage in ultra-endurance athletes. The study included 24 ultra-marathon runners and long-distance triathletes (12 male and 12 female) who underwent an acute exhaustive exercise test (a cycle ergometer (45 min at 65% VO2max) immediately followed by a treadmill test (75% VO2max to exhaustion). Oxidative stress-related biomarkers (8-isoprostaglandin F2alpha (8-iso PGF2a), total oxidant status (TOS, total antioxidant status (TAS)) in plasma were collected before and after exercise. Oxidative stress index was calculated to assess the aspect of r...

We aim to investigate the association between prevalence of FFMI values and use of nutritional supplement as an ergogenic aid among Turkish bodybuilders. One hundred twenty male bodybuilders included in this study. Their height and weight were measured and FFMI score were calculated. Nutritional supplements use was self-reported by bodybuilders. Data were analyzed using the IBM SPSS Statistics 23•0. Descriptive analyses were used to determine FFMI values of bodybuilders.

Design Randomised, crossover design. Participants Metabolically healthy twenty male subjects (10 normal weight; 10 obese) aged 19–40 years. Intervention Subjects consumed breakfast meals containing skimmed milk, fat-free white cheese, bread and EVCO (25 g) or EVOO (25 g). Outcome measures Visual analog scale evaluations, resting metabolic rate measurements and selected blood parameters analysis (glucose, triglyceride, insulin and plasma peptide YY) were performed before and after the test breakfast meals. In addition, energy intakes were evaluated by ad libitum lunch meal at 180 min. Results Visual analogue scale values of hunger and desire to eat decreased significantly after EVCO consumption than EVOO consumption in normal weight ...

We aimed to explore whether REE estimated by a bio-impedance (BIA) device or by the Harris-Benedict (HB) equation and TEE estimated by a BIA device may provide an alternative for IC and PAL measurements in HNC prior to surgery. Methods: REE was measured by IC (Cosmed k4b2). REE estimated by BIA (Bodystat1500) using the Brozek & Grande equation, and by adapted HB equation (Roza & Shizgal, 1984) were compared to measured REE. TEE estimated by BIA, i.e., from REE and reported physical activity was compared to measured TEE (REE by IC and daily PAL [MET equivalents] as measured by accelerometer [SWP3]). Agreement was explored with ICC (two-way mixed) and Bland Altman plots. ICC !0.80 was considered adequate, p-value <0.05 was considered significant. Results: A sample of 19 HNC patients (61.9±6.6 y; 63% male; stage 1: n¼5, stage 2: n¼9, stage 4: n¼5) were included. For REE, agreement between BIA and IC (ICC¼0.40, 95% CI: À0.06e0.72) and between HB and IC (ICC¼0.46, 95% CI: 0.02e0.75) was not adequate. Also for TEE, agreement between BIA and IC was not adequate (ICC¼0.14, 95% CI: À0.21e0.51). Bland-Altman plots for REE showed a mean difference of 35 kcal (p¼0.731, limits of agreement [LOA]: 989; À919 kcal) for BIA vs. IC, and À66 kcal (p¼0.525, LOA: 798; À929 kcal) for HB vs. IC. Mean difference of TEE for BIA vs. IC was 491 kcal (p¼0.02, LOA: 2146; À1164 kcal). Conclusions: In this sample of HNC patients, REE estimated by HB or BIA, and estimated TEE do not adequately agree with measured REE and TEE, respectively. Estimates of REE and TEE were widely distributed and estimated TEE overestimated measured TEE. Therefore, our results suggest that IC and accelerometer measurements cannot be replaced by BIA and HB estimates. Disclosure of interest: None declared.

Conclusions: The bariatric procedure leads to nutrient restriction which affects not only nutrient uptake but also nutrient diversity. Definition of food tolerance should be important for the overall evaluation of patient's condition after bariatric surgery (

It is not known whether daily intake of NZBC extract is required for effectiveness. Effects of daily and intermittent NZBC extract intake on cardiovascular responses were examined during brisk walking. Methods Fifteen healthy men (mean ± SD age: 24 ± 6 yr, body mass: 79 ± 16 kg, height: 178 ± 6 cm, BMI: 24.7 ± 4.3 kg·m−2, IPAQ score: 4534 ± 1576 MET·week−1) volunteered. Resting metabolic equivalent (1-MET) was measured using Douglas bags (1-MET: 3.97 ± 0.66 ml·kg−1·min−1) and an incremental walking test to determine the relationship between walking speed and MET. A randomised, cross-over (14-day washout) experimental design was used for baseline, 14-day intermittent (14I, every other day), and 14-day continuous (14C, daily) intake. Participants consumed 2 capsules of NZBC extract (600 mg and containing 210 mg of anthocyanins, CurraNZ™ H...
