Purpose The purpose of this study is to explore the association between intake of different types of dietary fats with breast cancer (BC) risk in Iranian women. Design/methodology/approach A total of 540 women (180 women with BC and 360 healthy women) were recruited from Shohadaye Tajrish hospital, Tehran, Iran. Data on anthropometric measurements, physical activity, smoking and alcohol consumption were collected. The food frequency questionnaire was used to assess the intake of fatty acids including saturated fatty acids, mono unsaturated fatty acids, poly unsaturated fatty acids, macronutrients, total fat, cholesterol, and calorie. Findings The cases had significantly higher BMI (29.19 ± 3.2 vs 27.27 kg/m2 ± 2.8) and higher intake of calorie (2737 ± 925 vs 2315 ± 1066 kcal/d, P = 0.01), carbohydrate (402 ± 125 vs 312 ± 170 kcal/d, P = 0.01) and ω−6 fatty acids (5.45 ± 6.9 vs 3.39 ± 0.59 g/d, P = 0.001) compared to the control group . Higher consumption of ω−6 fatty acids was related with higher risk of BC (OR = 5.429, CI95%:2.5–11.79, P = 0.001) The association between BC and intake of omega-6 fatty acids remained significant after adjustments for age, BMI, for using alcohol drinks, smoking, physical activity, calorie intake, protein intake and carbohydrate intake. Originality/value There are insufficient studies to investigate the association of different types of fatty acids with BC. This study found that higher omega-6 fatty acids intake was associated with increased risk of BC in women.

AbstrakRasio kolesterol total/ HDL merupakan variabel lipoprotein terbaik dalam memprediksi risiko penyakit kardiovaskular. Peningkatan risiko penyakit kardiovaskular dapat disebabkan oleh tingginya kadar kolesterol serum. Minyak sawit mengandung 50% asam lemak jenuh dan 50% asam lemak tidak jenuh. Tujuan penelitian ini adalah mengetahui perbedaan rasio kolesterol total/ HDL antara kelompok kontrol dengan kelompok diet tinggi minyak sawit pada tikus. Penelitian ini adalah eksperimental dengan pendekatan post test only control group design. Sampel penelitian terdiri dari 10 ekor tikus Wistar jantan yang dibagi menjadi kelompok kontrol (K) dan kelompok perlakuan (P). Diet tinggi minyak sawit (minyak sawit 42.5%, 3ml/hari) diberikan pada kelompok P selama empat minggu. Analisis data menggunakan uji t independent. Hasil penelitian menunjukkan terdapat perbedaan peningkatan yang tidak bermakna antara kelompok P dan kelompok K pada rerata kolesterol, yaitu 63.66±9.9(P) 57.39±3.28(K) (p>0.05), rerata HDL 19.44±3.99(P) 17.64±2.00(K) (p>0.05), dan rerata rasio kolesterol total/ HDL 3.26±0.24 (P) 3.31±0.32 (K) (p>0.05). Kesimpulan penelitian ini adalah kadar kolesterol total, HDL, dan rasio kolesterol total/ HDL pada kelompok kontrol dan kelompok diet tinggi minyak sawit tidak berbeda.Kata kunci: diet tinggi minyak sawit, kolesterol, HDL, rasio kolesterol/ HDLAbstractThe ratio of total cholesterol/ HDL is the lipoprotein variables best predict the risk of cardiovascular disease . The increased risk of cardiovascular disease can be caused by high levels of cholesterol exciting. Palm oil contains 50% saturated fatty acids and 50% unsaturated fatty acids. The purpose of this study was to know the differences ratio of total cholesterol/ HDL between the control group and high palm oil diet group in rats. This research was experimental with post-test only control group. The study sample consisted of 10 male Wistar rats were divided into control group (K) and treated group (P). High-palm oil diet (50% palm oil, 3ml/day) was given to the group P for four weeks. Analysis of data using independent t test. The results showed there were no significant differences in improvement between groups P and groups K in mean cholesterol, 63.66 ± 9.9 (P) 57.39 ± 3.28 (K) in (p> 0.05), mean HDL 19.44 ± 3.99 (P) 17.64 ± 2.00 (K) in (p> 0.05), and the mean ratio of total cholesterol/ HDL 3.26 ± 0.24 (P) 3.31 ± 0.32 (K) in (p>0.05).

AbstractBackground: A number of small intervention studies suggested that a Mediterranean diet (MedD) and physical activity can lower the risk for breast cancer. LIBRE is the first large multicenter RCT to test the effect of these lifestyle factors on the incidence of breast cancer in women at risk because of BRCA mutations(1). LIBRE also offers to unravel underlying mechanisms such as the role of short-chain fatty acids (SCFA) for beneficial effects of such lifestyle interventions.Methods: We examined the effect of the lifestyle intervention on the production of SCFA measured in feces by gas chromatography. From the ongoing LIBRE trial we included all complete datasets (171 women; mean age 44 ± 11 years). Both women with and without previous breast cancer diagnosis were recruited (diseased; non-diseased). The participants were randomized into an intervention group (IG) trained for MedD and physical activity, and a usual care control group (CG). Adherence to the MedD was assessed at baseline and after 3 months (V1) using the validated Mediterranean Diet Adherence Screener (MEDAS) and the EPIC food frequency questionnaire (FFQ).Results: At baseline there was no difference in SCFA levels between the groups. In the IG the MEDAS score increased substantially by 2.5 points (p < 0.001), in the CG only mildly by 0.4 points (p < 0.05). Correspondingly, the intake of fibers increased solely in the IG. In the course of the study the amount of caproic acid decreased in the control group (p < 0.001). At V1 non-diseased women showed higher amounts of acetic acid (p = 0.042), n-butyric acid (p = 0.023), n-valeric acid (p = 0.018) and iso-valeric acid (p = 0.031). There were several correlations between the intake of different fibers and fecal SCFA. For example, the sum of poly- and oligosaccharides correlated with acetic acid (p = 0.001; r = 0.316), propionic acid (p = 0.034; r = 0,251), n-butyric acid (p = 0.010; r = 0.316) and iso-valeric acid (p = 0.012; r = 0.306). There was no correlation between the MEDAS and SCFA.Discussion: A lifestyle change towards a MedD and increased physical activity did not change the levels of SCFA in feces, although an increase of fiber intake was documented in the IG. To further analyze SCFA metabolism in this target population, gut microbiota composition and function (metabolites) are currently analyzed.

Specific classes of dietary fatty acids may be important modifiers of breast cancer (B-Ca) risk. Aim of this study was identification risk of subtypes of dietary fat for B-Ca. This case–control study carried out in Rizgary Teaching Hospital in Erbil city. Data collected by interview questionnaire and included demographic and reproductive properties; anthropometric measurements; and medical history. Dietary data collected by food frequency questionnaire. They were analyzed by program for Mosby’s Nutritrac Nutrition Analysis Software, for calculation intake of dietary; fiber, total fat, and its subtypes, energy intake, acceptable macronutrient distribution range, and antioxidant nutrients. Statistical analysis was performed using SPSS program. Polyunsaturated fats decreased risk of B-Ca while saturated and monounsaturated fats (Cis form) increased risk among all and postmenopause obese women, respectively. Risk of cancer increased significantly in high percentage of energy intake from monounsaturated fats, cooking oil, and dietary red meats. The study concluded that total polyunsaturated fatty acids (PUFA) decrease risk of B-Ca among obese menopause woman. Increase risk of B-Ca by cooking oils and animal origin diet may due to increased intake of saturated monounsaturated and specific PUFA. These subtypes of dietary fats may promote hormones imbalance and inflammation.

Abstract Background: Deficiencies or imbalances in dietary fat intake may influence on mental and neurological functions of children with Autism Spectrum Disorders (ASD). This study aimed to compare the amount of fatty acids intake in the autistic cases with the healthy controls.Methods: This case-control was carried out on 200 randomly selected children (100 autistic cases and 100 healthy controls) in Tehran, Iran. The food frequency questionnaire (FFQ) was used to assess the intake of calorie, macronutrients, and dietary fatty acids including saturated fatty acids (SFA), monounsaturated fatty acids (MUFAs), poly unsaturated fatty acids (PUFAs), linoleic acid (LA), α-Linolenic acid (ALA), eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and trans fatty acids.Results: No significant difference was found in the amount of dietary calorie, protein, carbohydrate, and total fat intake between two groups. In terms of the type of dietary fatty acids, the amount of MUFAs (OR: 3.18(1.13-4.56); p=0.04), PUFAs (OR: 4.12(2.01-6.25); p=0.01), and LA (4.76(1.34-14.32); p=0.01) were significantly higher in ASD children compared to the control group. The amounts of ALA, EPA, DHA, SFA, and trans fatty acid were not significantly different between two groups. Conclusions: The autistic children had higher unsaturated fatty acids intake except for omega-3 fatty acids. Future longitudinal studies are needed to confirm these findings and to determine the underlying mechanisms of possible associations between unsaturated fatty acids intake and ASD.

555 Background: Accumulating data suggest that body weight and physical activity may affect breast cancer risk and outcomes. Biological mechanisms underlying these relationships are not clear. Studies have demonstrated that high levels of insulin, often seen in obese and sedentary individuals, are also associated with an increased risk of breast cancer recurrence and breast cancer-related death. We sought to analyze whether exercise lowers insulin levels in a population of breast cancer survivors. Methods: Inactive women with early stage breast cancer who had completed adjuvant treatment were randomized to a 16 week, mixed cardiovascular and strength training exercise intervention, or to a normal care control group. Target exercise goals included 2 supervised strength training sessions and 90 minutes of unsupervised cardiovascular exercise each week. Fasting insulin and glucose levels, as well as measurement of weight, body composition, and circumference at the waist and hip, were collected at baseline and after 16 weeks in both groups, and changes in these measures were assessed. Results: One hundred and one women were randomized. Comparison of changes in anthropometric measures are presented in Table 1 . Baseline insulin levels were similar in the 2 groups. After the 16-week exercise or control period, insulin levels decreased by 2.86 μIU/ml in the exercise group (p=0.03), and by 0.27 μIU/ml in the control group (p=0.65). A comparison of the change in insulin levels across time in the 2 groups approached statistical significance (p=0.07). There was also a trend toward improvements in insulin sensitivity in the exercise group (p=0.09), with no change seen in fasting glucose levels. Conclusions: Physical activity was associated with a decrease in insulin levels and in hip circumference in breast cancer survivors. The relationship between physical activity and breast cancer prognosis may be mediated, at least partially, through changes in insulin levels and/or changes in fat mass or deposition.

AbstractIntroduction. This study sought to evaluate the association between obesity factors (food consumption and physical activity) and breast cancer incidence in Korean women.Material and methods. The study included breast cancer patients (250 women) and normal participants undergoing medical checkups (250 women) who visited a specialized cancer research hospital between August 1, 2016 and February 15, 2017. Nutrient intake was assessed using a validated food frequency questionnaire (FFQ) covering 112 dishes and foods that Koreans often eat. Physical activity was assessed according to the International Physical Activity Questionnaire (IPAQ) guidelines and was quantified as metabolic equivalent (MET) scores.Results. The results for nutrient intake obtained using the FFQ showed that the control group had a higher consumption of dietary fiber (p < 0.004) and a lower intake of animal fat (p < 0.02) than the breast cancer group. Among breast cancer patients, pre-menopausal women consumed more animal fat (18.6 g ± 11.9 vs. 14.7 g ± 8.5, p < 0.03) than post-menopausal ones. An analysis of the MET scores with logistic regression revealed that lower physical activity among cancer patients was associated with an increased risk of breast cancer, and this association was greater among post-menopausal (OR = 2.11, p < 0.001) than pre-menopausal women (OR = 0.85, p < 0.02).Conclusion. Having a high-fat diet and doing less exercise increases the risk of breast cancer, so it is important to prevent the accumulation of fat and maintain proper weight through regular physical activity to lower the incidence of breast cancer.

Hypotheses. Sleep disorders are associated with an increased risk of cancer, including breast cancer (BC). Physical activity (PA) can produce beneficial effects on sleep. Study design. We designed a randomized controlled trial to test the effect of 3 months of physical activity on sleep and circadian rhythm activity level evaluated by actigraphy. Methods. 40 BC women, aged 35-70 years, were randomized into an intervention (IG) and a control group (CG). IG performed a 3 month of aerobic exercise. At baseline and after 3 months, the following parameters were evaluated both for IG and CG: anthropometric and body composition measurements, energy expenditure and motion level; sleep parameters (Actual Sleep Time-AST, Actual Wake Time-AWT, Sleep Efficiency-SE, Sleep Latency-SL, Mean Activity Score-MAS, Movement and Fragmentation Index-MFI and Immobility Time-IT) and activity level circadian rhythm using the Actigraph Actiwatch. Results. The CG showed a deterioration of sleep, whereas the IG showed a stable pattern. In the CG the SE, AST and IT decreased and the AWT, SL, MAS and MFI increased. In the IG, the SE, IT, AWT, SL, and MAS showed no changes and AST and MFI showed a less pronounced change in the IG than in the CG. The rhythmometric analysis revealed a significant circadian rhythm in two groups. After 3 months of PA, IG showed reduced fat mass %, while CG had improved weight and BMI. Conclusion. Physical activity may be beneficial against sleep disruption. Indeed, PA prevented sleep worsening in IG. PA can represent an integrative intervention therapy able to modify sleep behaviour.

SummaryFactor VII coagulant activity (FVIIc) is associated with an increased risk of fatal ischaemic heart disease (IHD). Several reports have suggested that dietary fat intake or hypertriglyceridaemia are associated with elevated levels of FVII. This study demonstrates that an intake of long-chain fatty acids sufficient to induce postprandial lipaemia in healthy subjects leads to a substantial elevation in both FVIIc and the concentration of FVII circulating in the activated form. Such an increase in FVIIc could not be induced by medium-chain triglycerides. These results suggest that the consumption of a sufficient amount of long-chain triglycerides to induce postprandial lipaemia induces the activation of FVII.

Recent evidence has highlighted that fat accumulation, particularly abdominal fat distribution, is strongly associated with metabolic disturbance. It is also well-recognized that the metabolic responses to variations in macronutrients intake can affect body composition. Previous studies suggest that the quality of dietary fats can be considered as the main determinant of body-fat deposition, fat distribution, and body composition without altering the total body weight; however, the effects of dietary fats on body composition have controversial results. There is substantial evidence to suggest that saturated fatty acids are more obesogen than unsaturated fatty acids, and with the exception of some isomers like conjugate linoleic acid, most dietary trans fatty acids are adiposity enhancers, but there is no consensus on it yet. On the other hand, there is little evidence to indicate that higher intake of the n-3 and the n-6 polyunsaturated fatty acids can be beneficial in attenuating adiposity, and the effect of monounsaturated fatty acids on body composition is contradictory. Accordingly, the content of this review summarizes the current body of knowledge on the potential effects of the different types of dietary fatty acids on body composition and adiposity. It also refers to the putative mechanisms underlying this association and reflects on the controversy of this topic.
