RESUMO

Dietary quality is an important factor in the etiology of breast cancer (BrCa), but further studies are required to better elucidate this relationship. Accordingly, we sought to analyze if diet quality, assessed using the Diet Quality Index-International (DQI-I), Mean Adequacy Ratio (MAR), and Dietary Energy Density (DED), was related to BrCa. In this Hospital-based case-control study, 253 patients with BrCa and 267 non BrCa controls were enrolled. Individual food consumption data from a food frequency questionnaire was used to calculate the Diet Quality Indices (DQI). Employing a case-control design, odds ratios (ORs) and 95% confidence intervals (CIs) were obtained, and a dose-response analysis investigated. After adjusting for potential confounders, those in the highest quartile of the MAR index had significantly lower odds of BrCa than those in the lowest (OR = 0.42, 95% CI 0.23-0.78; P for trend = 0.007). Although there was no association between individual quartiles of the DQI-I and BrCa, there was evidence of a significant trend across all the quartile categories (P for trend = 0.030).There was no significant association was found between DED index and the odds of BrCa in the crude and fully adjusted models. We found that higher MAR indices were associated with decreased odds of BrCa, Therefore, the dietary patterns reflected by these scores may serve as a possible guide to preventing BrCa in Iranian women.

RESUMO

This study aimed to determine the relationship between food pattern and dietary intake before and during chemotherapy with the severity of gastrointestinal side effects, cancer-related fatigue, and chemotherapy-induced pain. This study was performed on 204 patients with breast cancer who were undergoing chemotherapy. Dietary pattern was collected by food frequency questionnaire and dietary intake during chemotherapy using a 24-hour food recall questionnaire. The severity of chemotherapy side effects including nausea, vomiting, constipation, diarrhea, CRF, and pain was also assessed by valid questionnaires. The relationship between dietary pattern and mean score of chemotherapy side effects was calculated using linear regression analysis. Three dietary patterns were extracted from the participants. After adjusting the effect of all possible confounders, no significant relationship was found between the dietary pattern one year before the start of treatment and the mean of chemotherapy side effects severity. Although the mean of daily energy intake with the severity of nausea and vomiting (r = -0.258, P-value <0.01), constipation, fatigue, and pain have a significant inverse relationship. Nutrition education and following a healthy diet are needed to reduce the severity of chemotherapy side effects during this period.

RESUMO

Evidence suggests the role of changing traditional lifestyle patterns such as Paleolithic to modern lifestyle in the incidence and epidemic of chronic diseases. Thus, this study aimed to investigate the association between Paleolithic diet (PD) and risk of Breast Cancer (BC) in adult Iranian women. This matched case-control study included 253 women with BC and 267 healthy women aged >18 years. PD score was evaluated using a validated 168-item quantitative food frequency questionnaire. Conditional logistic regression model was used to estimate odds ratios (ORs) and 95% confidence intervals (95%CIs), and dose-response was investigated. Mean of PD score was 39.00 ± 6.39. Among the food groups of the PD components, BC patients significantly had lower consumption of healthy food groups as vegetables, fruits, fish, and nuts, higher intakes of sugar-sweetened beverages as well as grains and starches. After adjustment for potential confounders, comparing the highest quartile of PD scores with the lowest quartile, a decrease in the risk of BC was observed for all women (OR: 0.26; 95% CI: 0.13-0.53), as well as those premenopausal (OR: 0.29; 95% CI: 0.11), and postmenopausal (OR: 0.17; 95% CI: 0.05 - 0.56). Our findings show that adherence to the PD pattern significantly reduces the risk of BC in the population studied. However, prospective studies are needed to further investigate this association.

RESUMO

We aimed to examine whether anthropometric indices, dietary factors, and nutrient intakes of women with and without breast cancer (BrCa) are associated with the oxidative balance score (OBS). This case-control study was carried out among 253 patients with BrCa and 267 healthy subjects aged >18 years. The OBS was calculated by using the following 13 dietary and non-dietary anti- and prooxidant components: dietary antioxidants (selenium, fiber, ß-carotene, vitamin D, vitamin C, vitamin E, and folate), dietary prooxidants (iron and saturated and polyunsaturated fatty acids), and nondietary anti- (physical activity) and prooxidants (smoking and obesity). The binary logistic regression was used to determine the association OBS with BrCa. After adjusting for potential confounders in the final model, there was evidence that the odds of BrCa decreased with increasing categories of the OBS (OR = 0.53, 95% CI 0.28 - 0.98; P-trend = 0.021). When we made stratified analysis by menopausal status, OBS was inversely associated with odds of BrCa in premenopausal women after adjusting for potential confounders. No significant association was found between OBS and odds of BrCa among post-menopausal women. Our data suggest that OBS scores were associated with decreased BrCa risk in the overall population.

RESUMO

Recently, the use of synbiotics for managing various diseases has dramatically increased. Synbiotics have been shown to be a good approach to influence the composition of the gut microbiota with positive health effects. Management of type 2 diabetes mellitus (T2DM) complications is one of the reasons for the ingestion of synbiotics and so the aim of the current study was to determine the effects of synbiotic bread intake on markers of lipid profile in T2DM patients. One hundred T2DM patients (age between 20 and 60 years) were randomly assigned to four groups to consume different types of synbiotic bread, three times/day, for 8 weeks: "synbiotic + lactic acid" (n = 25; IV), "synbiotic" (n = 25; III), "lactic acid brad" (n = 25; II), or "control" (n = 25; I). The measured outcomes included anthropometric characteristics, glycemic control parameters, blood lipids, and apolipoproteins. The consumption of "synbiotic + lactic acid bread" (group IV) and "lactic acid bread" (group II) led to a significant decrease in total cholesterol (TC) and glycated hemoglobin (HbA1c) compared to the "control bread." The HbA1c levels were also significantly lower when compared to group II. Additionally, apolipoprotein A (Apo A1) levels were significantly decreased in group IV, compared to control and other groups (post hoc analysis). No significant differences between groups were observed for triglyceride (TG), high-density lipoprotein (HDL), low-density lipoprotein (LDL), and apolipoprotein B100 (Apo B100) levels. The observed results show that the synbiotic bread (with or without lactic acid) promoted a decrease in total cholesterol (TC) and Apo A1 in diabetic patients when consumed daily for 8 weeks.

RESUMO

Breast cancer (BC) can negatively influence multiple facets of survivors' lives including mental health, quality of life (QoL), and dietary behavior. Logotherapy as a psycho-education program may help breast cancer survivors (BCSs) discover their meaning of life throughout distressful events. The present study aimed to determine the effects of logotherapy along with nutrition counseling on psychological status, QoL, and dietary intake among BCSs who were diagnosed with depression.This randomized clinical trial was conducted on 90 BCSs who scored ≥ 14 on Beck's depression test. Participants were randomly assigned into two groups to receive nutrition counseling plus logotherapy (n = 46) or nutrition counseling alone (n = 44) for 8 weeks. Primary outcomes (depression, anxiety, and QoL) and secondary outcomes (anthropometric indices, dietary intake, and eating disorder status) were measured at baseline and after 8 weeks.All dimensions of QoL, anthropometric measurements, and the compulsive eating scale improved significantly in both groups after 8 weeks. A combination of nutrition counseling and logotherapy resulted in a significant reduction in anxiety (P < 0.001) and depression (P < 0.001) scores compared with the nutrition counseling alone. In addition, participants who received logotherapy plus nutrition counseling significantly consumed less energy, carbohydrate, and fat intake after 8 weeks compared with the control group (P < 0.001).It can be concluded that logotherapy along with nutrition education would be an important step in improving anxiety, depression, and QoL of patients with BC who had depressive symptoms.Trial registration number: (IR.ACECR.IBCRC.REC.1396.17).

RESUMO

Background: Previous evidence suggests a link between diet quality and breast cancer (BrCa); however, the link between the Lifelines Diet Score (LLDS)-a fully food-based score that uses the 2015 Dutch Dietary Guidelines-and risk of BrCa has not yet been evaluated. Therefore, the aim of this study was to observe the relationship between adherence to an LLDS and risk of BrCa in Iranian adults. Methods: In the hospital-based case-control study, 253 patients with BrCa and 267 non-BrCa controls were enrolled. Individual's food consumption was recorded to calculate LLDS using a semiquantitative food frequency questionnaire. In adjusted models, the association between the inflammatory potential of the diet and the risk of BrCa was estimated by using binary logistic regression. Results: Compared with control individuals, BrCa patients significantly had higher waist circumference (WC), first pregnancy age, abortion history, and number of children. In addition, the mean intake of vitamin D supplements and anti-inflammatory drugs in the case group was significantly lower than the control group. Furthermore, after adjusted potential confounders, individuals in the highest vs. lowest quartiles of LLDS showed statistically significant lower risk of BrCa in overall population (OR: 0.21; 95% CI: 0.11-0.43; P trend <0.001), premenopausal (OR: 0.26; 95% CI: 0.10-0.68; P trend = 0.003), and post-menopausal women (OR: 0.20; 95% CI: 0.06-0.60; P trend = 0.015). Conclusion: Findings of this study reflected that higher LLDS decreased risk of BrCa, but need further investigation in later studies.

RESUMO

This systematic review and meta-analysis aimed to investigate the effect of dietary-based lifestyle modification interventions ("diet," or "diet + exercise," or "diet + exercise + behavioral" intervention) on the measures of anthropometric and dietary intake parameters in women with breas cancer (BC). Databases were searched until June 2021. Inclusion criteria were randomized controlled trials that enrolled only women with BC. Studies that used exercise or behavioral interventions alone were not included. Mean ± SD changes were extracted for each outcome, and pooled using a random-effects model; 7315 studies were identified. Fifty-one studies (n = 7743) were included. The median ± SD duration of treatment was 24 ± 16.65 wk. Dietary-based interventions significantly reduced body weight [45 studies (n = 7239), weighted mean difference (WMD) (95% CI): -2.6 (-3.2, -2.1) kg], BMI [31 studies (n = 5384); WMD (95% CI): -1.0 (-1.3, -0.7) kg/m2], lean body mass [15 studies (n = 1194); WMD (95% CI): -0.6(-0.7, -0.4) kg], fat mass [11 studies (n = 913); WMD (95% CI): -2.6 (-3.3, -1.8) kg], fat percentage [17 studies (n = 897); WMD (95% CI): -1.5 (-1.9, -1.3)%], hip circumference [9 studies (n = 489); WMD (95% CI): -2.43 (-3.34, -1.54) cm], and waist circumference [7 studies (n = 309); WMD (95% CI): 0.02 (-0.03, -0.005) cm]. Significant reductions in energy intakes [20 studies (n = 4608), WMD (95% CI): -162 (-220, 104) kcal/d] and fat intakes [7 studies (n = 4316), WMD (95% CI): -7.5 (-7.8, -7.2)% of energy/d], and an increase in fiber intakes [11 studies (n = 4241), WMD (95% CI): 2.4 (0.7, 4.1) g/d] were observed. No significant changes were seen in protein, carbohydrate, and fruit and vegetable intakes. Subgroup analyses showed that changes in anthropometric and dietary intake indices were significant in studies that enrolled patients with both obesity and normal weight, studies that used diet therapy in combination with exercise and behavioral therapy, and studies that started the intervention during the treatment period. Overall, a multimodal dietary-based lifestyle intervention had significant effects on anthropometric and dietary intake parameters in women with BC, specifically when started as early as the diagnosis. This meta-analysis was registered at PROSPERO as CRD42021291488.

RESUMO

OBJECTIVES: Despite the widespread use of complementary and alternative medicine by patients and physicians alike, there is no accurate evidence regarding the effects of vitamin D supplementation on treatment-induced pain in cancer patients. Thus, the aim of this systematic review of randomized controlled trials (RCTs) was to evaluate the impact of vitamin D administration on therapy-related pain in subjects diagnosed with malignant disorders. REVIEW ANALYSIS METHODS: We searched the Web of Science, Scopus, PubMed/Medline, Embase, and Google Scholar databases up to October 2020 to identify published RCTs that investigated the use of vitamin D in the management of treatment-induced pain in individuals with cancer. RESULTS: Nine RCTs were detected. The median duration of the intervention was of 24 weeks (range 12-52 weeks) and dose of vitamin D employed was 2000-50000 IU of vitamin D3 weekly orally each day. Six RCTs reported a significant reduction in pain, whereas three did not detect a notable decrease of this variable. Of the six studies that reported an alleviation of pain, an RCT which recruited 60 participants and lasted for 24 weeks consisted of supplementation with high doses of vitamin D2 weekly for 8 weeks in women receiving anastrozole as adjuvant therapy, then supplementation with vitamin D2 monthly for 4 months, effectively alleviated the aromatase inhibitor-associated musculoskeletal syndrome (AIMSS). The results of the same RCT also suggested a beneficial effect of vitamin D on musculoskeletal pain. CONCLUSIONS: Our results suggest that the supplementation with high doses of vitamin D in cancer patients with low serum levels of vitamin D, can be effective in reducing treatment-related pain.

RESUMO

BACKGROUND: Pro-inflammatory diet and lifestyle factors lead to diseases related to chronically systemic inflammation. We examined the novel dietary/lifestyle indicators related to inflammation such dietary inflammation score (DIS), lifestyle inflammation score (LIS), empirical dietary inflammatory index (EDII) and, risk of Breast Cancer (BrCa) in Iranian woman. METHODS: In this hospital-based case-control study, 253 patients with BrCa and 267 non-BrCa controls were enrolled. Food consumption was recorded to calculate the DIS, LIS and EDII using a semi-quantitative Food Frequency Questionnaire (FFQ). We estimated odds ratios (ORs) and, 95% confidence intervals for the association of the inflammatory potential with risk of these cancers using binary logistic regression models modified for the case-control design. RESULTS: Mean ± SD of age and BMI of the study participants were 47.92 ± 10.33 years and 29.43 ± 5.51 kg/m2, respectively. After adjustment for confounders, individuals in highest compared to lowest quartile of DIS and EDII had significantly higher risk of BrCa (DIS: 2.13 (1.15 - 3.92), p-trends: 0.012), EDII: 2.17 (1.12 - 4.22), p-trends: 0.024). However, no significant association was observed for LIS (P-trends: 0.374). CONCLUSION: Findings of this study suggested that higher DIS and EDI increased the risk of BrCa, but concerning LIS, further investigation is needed.

RESUMO

BACKGROUND AND AIM: Breast cancer-related lymphedema (BCRL) is a treatment-related inflammatory complication in breast cancer survivors (BCSs). This study was aimed to evaluate the effect of synbiotic supplementation on serum concentrations of IL-10, TGF-ß, VEGF, adiponectin, and edema volume among overweight or obese BCSs with lymphedema following a low-calorie diet (LCD). METHOD: In a randomized double-blind, controlled clinical trial, 88 obese and overweight BCSs women were randomized to synbiotic supplement (n = 44) or placebo (n = 44) groups and both groups followed an LCD for 10 weeks. Pre- and post-intervention comparisons were made regarding the anti-inflammatory markers which included IL-10, TGF-ß, VEGF, adiponectin, edema volume, and anthropometric measurements. Also, the same factors were analyzed to find inter-group disparities. RESULTS: There were no significant differences among participants in the baseline, except for IL-10 and adiponectin. Post-intervention, no significant differences were observed regarding the anti-inflammatory markers, including IL-10, VEGF, adiponectin, and TGF-ß between the groups. After 10 weeks of intervention edema volume significantly decreased in the synbiotic group; additionally, anthropometric measurements (body weight, BMI, body fat percent, and WC) decreased in both groups significantly (P < 0.001 and P < 0.005; respectively). CONCLUSION: Synbiotic supplementation coupled with an LCD in a 10-week intervention had beneficial effects on increasing the serum TGF-ß, IL-10, and adiponectin levels in women with BCRL. It also reduced arm lymphedema volume. Therefore, synbiotic supplementation can be effective in improving health status in BCRL patients.

RESUMO

BACKGROUND: Although there is ample evidence for the effect of omega-3 supplementation on seizure frequency in individuals with epilepsy, the results are inconsistent. Therefore, we conducted this systematic review and meta-analysis to elucidate the potential effect of omega-3 supplementation in the adult and pediatric population. METHODS: Clinical trials articles were searched in electronic databases (Web of Science, Scopus, PubMed/Medline, Embase, and Google Scholar database up to October 2020). No language limitation was imposed in the literature search. Moreover, gray literature search was done via searching the references of identified review papers to find more potentially relevant articles. RESULTS: In order, the duration of the intervention and dosage of omega-3 fatty acid supplement of the included studies ranged from 12 to 42 weeks and 1000-2880 mg/day. Pooled results from the random-effects model indicated that seizure frequency following supplementation of omega-3 fatty acid decreased significantly (WMD: -6.15, 95% CI: -7.78, -4.53, P < 0.001). Furthermore, the results of the subgroup analysis revealed that seizure frequency was more alleviated in studies that used a daily dose of 1500 mg or less of omega-3 fatty acids as well as studies that had an intervention duration of more than 16 weeks. More importantly, our findings also showed that the effect of omega-3 intervention was greater in adults than in children with epilepsy. CONCLUSION: The current meta-analysis on available trials suggested that omega-3 supplementation resulted in beneficial effects on seizure frequency in adult and children with epilepsy.

RESUMO

PURPOSE: Adipokines and inflammatory factors can affect breast cancer (BC) prognosis and recurrence among breast cancer survivors (BCSs). This study was to evaluate the effects of synbiotic supplementation along with a low-calorie diet on some recurrence-related factors such as adiponectin, tumor necrosis factor-alpha (TNF-α), and high-sensitivity C-reactive protein (hs-CRP) among obese and overweight BCSs. METHODS: We performed a randomized, triple-blind, placebo-controlled clinical trial among 76 overweight or obese postmenopausal women with a history of hormone-receptor-positive BC. Participants were randomly divided into 2 groups to intake either 109 CFU/day synbiotic supplement or placebo (n = 38 each group) for 8 weeks. All participants were given a low-calorie diet program. The primary outcome was serum concentration of adiponectin which was measured at baseline and after 8 weeks. RESULTS: Compared with the placebo, synbiotic intake significantly increased adiponectin (+ 13.58 (10.08, 18.17) vs. - 0.42 (- 2.90, 1.98) µg/ml; P < 0.001). In addition, synbiotic supplementation resulted in significant reduction in TNF-α levels (- 17.09 (- 32.05, - 13.60) vs. 0.20 (- 3.97, 2.00) ng/L; P < 0.001) and hs-CRP levels (- 1.14 (- 1.90, - 0.88 vs. - 0.06 (- 0.38, 0.15) mg/L; P < 0.001) compared with the placebo. CONCLUSIONS: In conclusion, 8-week synbiotic consumption by overweight and obese postmenopausal BCSs had beneficial effects on adiponectin, TNF-α, and hs-CRP.

RESUMO

BACKGROUND: The investigation was designed to assess the effects of synbiotic supplementation on glycemic profile, insulin-like growth factor-1 (IGF-1) and sex hormones in overweight and obese postmenopausal breast cancer survivors (BCSs) who had hormone-receptor-positive breast cancer. METHODS: This randomized, triple-blind, placebo-controlled trial was conducted on 76 overweight and obese BCSs aged 57.43 (5.82) years. All participants were given a specified low calorie diet and were randomly assigned into two groups to intake 109 CFU/day of synbiotic supplement (n = 38) or placebo (n = 38) for 8 weeks. Body composition, physical activity, glycemic profile, IGF-1, estradiol, testosterone and dehydroepiandrosterone sulfate (DHEA-S) were measured at baseline and after 8 weeks. RESULTS: A significant reduction in serum insulin (median change (Q1, Q3) from baseline of -1.05 (-2.36, 0.32) µIU/mL; P = 0.006) and insulin resistance (HOMA-IR) (mean change (SD) from baseline of -4.0 (0.9); P = 0.007) were seen over the 8 weeks in the synbiotic group. However, no significant changes were observed in serum insulin, fasting plasma glucose, HbA1c, HOMA-IR, IGF-1, estradiol, testosterone, DHEA-S and sex hormone binding globulin between-groups at the end of the intervention. CONCLUSIONS: Overall, as the 8-week synbiotic consumption compared with placebo had insignificant-reducing effects on glycemic profile, IGF-1 and sex hormones among overweight and obese postmenopausal BCSs, synbiotics may exert considerable beneficial consequences, which need to be further assessed in future clinical trials.

RESUMO

We aimed to evaluate the effect of dried Ziziphus vulgaris [Z. vulgaris] consumption on liver enzymes, blood pressure, inflammatory status, glycemic control, and lipid concentrations in type 2 diabetes patients. Seventy-six diabetic participants (aged 20-65 years) randomly assigned to intervention (n = 38) and placebo (n = 38) groups. The intervention group received 30 g/day dried Z. vulgaris for 12 weeks. At the end of the study, there was a significant reduction in the percentage change of weight, body mass index [BMI], insulin, homeostasis model assessment-insulin resistance [HOMA-IR], Apoprotein B100 [ApoB100], and high-sensitive c-reactive protein [hs-CRP] in the intervention group compared to the controls. Also, increased values of quantitative insulin check index [QUICKI] and Apoprotein A-I [ApoA-I] in Z. vulgaris group compared to the controls were observed. In conclusion, consumption of dried Z. vulgaris fruit could have beneficial effects on improving the glycemic control and reducing the cardiovascular risk factors in the diabetic patients. PRACTICAL APPLICATIONS: In the present study we found that consumption of 30 g/day dried Z. vulgaris fruit in patients with type 2 diabetes for 12 weeks has beneficial anti-inflammatory, anti-hyperglycemic, and anti-hyperlipidemic effects on type 2 diabetes mellitus [T2DM] patients compared to the control group. Thus, it seems reasonable to design a large-scale clinical trial to determine the potential adverse effects of higher doses of this fruit and identify the therapeutic doses for the complementary treatment in T2DM medication. The medication with this popular fruit as an ingredient could be easily accepted by diabetic patients and may reduce the dependency and dosage of some of the routine diabetes medications which often have some adverse side effects.

RESUMO

BACKGROUND AND AIMS: Improved vitamin D levels can have a favorable effect on some metabolic variables. The objective of the current study was to determine the effects of vitamin D supplementation during a weight-loss intervention on the levels of omentin-1, spexin, lipid profiles, and inflammatory factors in obese and overweight participants. METHODS AND MATERIALS: In this double-blind placebo-controlled randomized clinical trial, 70 overweight and obese participants with vitamin D deficiency (25(OH)D ≤ 20 nmol/L) were assigned into the intervention (a daily dose of 2,000 IU vitamin D + low-calorie diet) and placebo (placebo + low-calorie diet) groups for 8 weeks. Anthropometric parameters, serum levels of 25-hydroxy vitamin D (25(OH)D), lipid profiles, omentin-1 and spexin levels, high-sensitivity C-reactive protein (hs-CRP), and soluble intercellular adhesion molecule-1 (sICAM-1) concentrations were assessed before and after the intervention. RESULTS: Vitamin D supplementation after the intervention led to a significant decrease in triglycerides (TG) (P = 0.02), very-low-density lipoprotein-cholesterol (VLDL-C) (P = 0.02), and hs-CRP (P = 0.03) concentrations and a significant increase in the serum vitamin D level (P < 0.001). Furthermore, after adjusting for baseline values, age, and baseline BMI, the levels of serum high-density lipoprotein-cholesterol (HDL-C) (P = 0.01) increased significantly, and a significant reduction was observed in the concentration of sICAM-1 (P = 0.01) in the intervention group. However, we did not find any significant difference in serum omentin-1 and spexin concentrations between the groups after intervention. CONCLUSIONS: Vitamin D supplementation along with a low-calorie diet (LCD) program for 8 weeks significantly decreased the inflammatory markers in obese individuals, while it did not alter serum omentin-1 and spexin concentrations.

RESUMO

BACKGROUND: Little evidence exists regarding the clinical value of synbiotics in the management of post-treatment complications of breast cancer especially breast cancer-related lymphedema (BCRL). This study aimed to investigate the effects of synbiotic supplementation along with calorie restriction on quality of life and edema volume in patients with BCRL. METHODS: This randomized, placebo-controlled, clinical trial was conducted on 135 overweight and obese women with BCRL aged 18-65 years old. Participants were randomly allocated to receive a calorie-restricted diet plus 109 CFU synbiotic supplement (CRS group; n = 45) or placebo (CRP group; n = 45), daily for 10 weeks. Also, a control group (n = 45) with no intervention was included in the trial. All of the participants received Complete Decongestive Therapy for lymphedema treatment. The quality of life score, edema volume and body mass index (BMI) were measured at baseline and end of the trial. RESULTS: A total of 121 subjects completed the trial. CRS group showed a significant decrease in the total quality of life score (P = 0.004), and it's psychosocial (P = 0.022) and functional (P = 0.002) domain scores, as well as edema volume (P = 0.002) and BMI (P < 0.001) in comparison to the control. However, there were no significant differences in changes in trial outcomes between the CRS and CRP groups. CONCLUSION: Synbiotic supplementation along with a low-calorie diet was effective in quality of life, edema volume, and BMI improvement; mostly due to low-calorie diet. It seems that adding a dietitian consultation on the lymphedema management strategy may provide a better result in lymphedema control.

RESUMO

BACKGROUND & AIMS: Kidney stone is a life-threatening disease with subsequent complications, especially in children who overtake this disease in early ages. This study assessed the effect of kidney stone history on current blood pressure and growth parameters of children. METHODS: A two hundred children with (n = 100) and without (n = 100) a history of urolithiasis from Pediatric Urology clinics at the Aliasghar hospital, Tehran, Iran, participated in this case-control study. Several demographic data, height, weight, body mass index (BMI), BMI for age and blood pressure index were measured as the primary outcomes. RESULTS: type of birth and infancy feeding, carbohydrate and energy intake were significantly different between the two groups (P = 0.008, 0.002, 0.03 and < 0.001 respectively). Ordinal logistic regression analysis showed that the current weight (P = 0.001) and BMI for age (P = 0.02) of the stone formers were lower than the non-stone formers, while no significant association found between the blood pressure or current height and the history of urolithiasis. CONCLUSION: Our findings suggest that childhood urolithiasis has no significant effect on growth failure and blood pressure in childhood but it has a little impact on weight and BMI for age in older ages.

RESUMO

Breast cancer-related lymphedema (BCRL) is one of the most common complications of breast cancer treatments, which may be exacerbated by obesity. Dysbiosis may negatively impact the management of obesity and lymphedema by increasing inflammation. The objective of this study was to assess the effects of supplementation with synbiotics on inflammatory markers, serum leptin concentration and edema volume in overweight and obese BCRL women following a low-calorie diet (LCD). In a randomized double-blind controlled clinical trial, 88 breast cancer survivors with lymphedema were supplemented once a day for 10 weeks with either a synbiotic or a placebo capsule. Both groups were under a low-calorie diet (LCD). At the end of the study, synbiotic supplementation resulted in a significant reduction in leptin (P=0.003) and TNF-α (P=0.039) between the study groups. Besides, edema volume was significantly reduced within the synbiotic group after the intervention. We did not observe any significant effects of the synbiotic supplementation in hs-CRP, and IL-1ß between the study groups (P=0.550, P=0.118 respectively). Conclusively, synbiotic supplementation along with an LCD program in breast cancer survivors with lymphedema had beneficial effects on the concentration of serum inflammatory markers and edema volume.

RESUMO

Background and Aims: Synbiotics found to be beneficial in breast cancer survivors (BCSs) through its antioxidant properties. The aim of this study was to assess the effects of synbiotic supplementation on edema volume and some oxidative markers among obese and overweight patients with BCRL.Method: This randomized double-blind, placebo-controlled trial was conducted on 88 overweight and obese BCSs aged 18-65 years. All the subjects were given a specified low-calorie diet (LCD) and were randomly assigned into two groups to intake 109 CFU/day synbiotic supplement (n = 44) or placebo (n = 44) for 10 wk. Edema volume and serum total antioxidant capacity (TAC), malondialdehyde (MDA), glutathione peroxidase (GPx), and superoxide dismutase (SOD) concentration were measured at baseline and after the 10-wk intervention.Results: Ten-wk supplementation with synbiotics leads to a significant reduction in serum MDA levels (P = 0.001) and an increase in serum SOD concentration (P = 0.007) compared to placebo. No significant changes were observed in serum GPx, TAC, and edema volume between groups.Conclusion: Our findings reveal that 10-wk synbiotic supplementation along with a LCD program-reduced serum MDA levels and elevate the activity of SOD in overweight and obese patients with BCRL. However, its effect on serum GPx, TAC, and edema volume was not significant.
