RESUMEN
BACKGROUND: Multiple sclerosis (MS) is accompanied by many health-related issues. This study aimed to evaluate the anthropometric indices, nutrient intakes and health-related characteristics of MS patients as well as their possible correlations. METHODS: This cross-sectional study was performed on 283 MS patients in Shiraz, Iran, during 2018-2019. Body mass index (BMI) and body composition were measured for each participant. A food frequency questionnaire was used to determine the patients' nutrient intakes. The level of fatigue, disability and quality of life of the individuals were assessed by the modified fatigue impact scale (MFIS), the expanded disability status scale and the multiple sclerosis quality of life-54 questionnaires, respectively. RESULTS: The results revealed that 43.11% of the patients were overweight or obese, and their %body fat (%BF) was 35.65 ± 7.63. Besides, intakes of vitamins A, E, D, folic acid, calcium, zinc and magnesium were significantly lower than recommendations in both genders, and sodium intake was significantly higher than the tolerable upper intake level in females. A significant positive linear correlation was observed between MFIS and BMI (r = 0.12, P = 0.045). Significant positive correlations were also found between psychosocial subscale of MFIS and both of %BF (r = 0.12, P = 0.049) and visceral fat area (r = 0.14, P = 0.02). Unexpectedly, the patients' quality of life showed significant negative correlations with fat free mass and skeletal muscle mass. CONCLUSION: Being overweight, having a high %BF and poor nutrient intakes are common among MS patients. Improving the patients' lifestyle and dietary intake is recommended to reduce fatigue and increase their life quality.
RESUMEN
BACKGROUND: The sarcopenia quality of life (SarQoL)® questionnaire is a specific tool to measure QoL in sarcopenia. The aim of this study was to validate the SarQoL® questionnaire for evaluation of sarcopenia-related quality of life in Iranian community-dwelling older adults. METHODS: Validity (discriminative power, construct validity), reliability (internal consistency, test-retest reliability), and floor/ceiling effects of SarQoL® questionnaire were evaluated in the current study. Moreover, the SarQoL® questionnaire was compared with the Short-Form 36-item (SF-36) and the EuroQoL 5-Dimensions (EQ-5D) questionnaires. RESULTS: Among 501 community-dwelling older adults, 128 elderly participants (including 88 sarcopenic individuals) were recruited for validation. Participants with sarcopenia had lower quality of life than non-sarcopenic individuals (Total Score: 39.37 ± 7.45 vs. 65.09 ± 7.85, p < 0.001). Also, the findings demonstrated a high internal consistency (Cronbach's alpha of 0.881), excellent test-retest reliability (ICC = 0.995, 95% CI 0.990-0.998), and no floor/ceiling effect of SarQoL® questionnaire. CONCLUSION: This is the first study to confirm the reliability and validity of the Persian version of the SarQoL® for the measurement of quality of life among Iranian sarcopenic older adults.

Nutritional interventions can be valuable for the prevention of postmenopausal osteoporosis. This study aimed to investigate the effects of kefir fortified with omega-3 and vitamin C on the bone and uterus parameters of ovariectomized rats. Seventy-seven female Sprague-Dawley rats were ovariectomized or sham-operated. The ovariectomized rats were assigned to six groups and received 1 ml/day of distilled water (OVX group), milk, kefir, kefir fortified with omega-3 fatty acids (kefir+ω3), kefir fortified with vitamin C (kefir+vit-C) or kefir fortified with omega-3 and vitamin C (kefir+ω3+vit-C) for 12 weeks. The sham group also received 1ml/day of distilled water. Subsequently, bone mineral content (BMC) and bone mineral density (BMD) of various bones were assessed. Femurs and uteri were harvested for bone ash analysis and histopathological examinations, respectively. Sera were analyzed for carboxy-terminal cross-linked telopeptide of type 1 collagen, procollagen type 1 amino-terminal propeptide, calcium, phosphorous, tumor necrosis factor-α (TNF-α) and total antioxidant capacity levels. Ovariectomy resulted in significant reduction in bone density (P<0.05). Kefir+ω3+vit-C significantly improved BMC of lumbar spine (0.699±0.027 g compared with 0.580±0.018 in the OVX group), and kefir, kefir+vit-C and kefir+ω3+vit-C significantly increased BMD of tibia (0.118±0.003 g/cm2, 0.119±0.001 and 0.120±0.004 compared with 0.102±0.005 in the OVX group). Moreover, ovariectomy markedly elevated TNF-α level, which was significantly reversed by kefir+ω3+vit-C. Significant atrophy of the uterus was observed following ovariectomy, although the uterus parameters did not change by any of the interventions. In conclusion, kefir fortified with omega-3 fatty acids and vitamin C may have protective effects against bone loss through suppressing inflammation.

This study aimed to evaluate the effects of licorice root supplementation on liver enzymes, hepatic steatosis, metabolic and oxidative stress parameters in women with nonalcoholic fatty liver disease (NAFLD). In this randomized double-blind, placebo-controlled trial, 60 women with NAFLD were selected and randomly assigned into 2 groups to take 1,000 mg/day powder of licorice root extract or placebo for 12 weeks. In addition, all the patients were advised to follow a weight loss diet and healthy lifestyle. The plasma levels of liver enzymes, glycemic indices, lipid profile, oxidative stress parameters, as well as hepatic steatosis were measured at the beginning and end of the study. Through the 12-weeks period of supplementation, women who received powder of licorice root experienced a statistically significant improvement in alanine aminotransferase (p < .001), insulin (p = .002), insulin resistance (p = .003), malondialdehyde (p < .001) serum levels, and ultrasonographic findings of liver steatosis (p < .001), compared to the placebo group. In conclusion, licorice root supplementation in addition to gradual weight loss and lifestyle modification is superior to lifestyle modification alone for the treatment of NAFLD.

Introduction: Melon seeds, as an excellent source of protease inhibitors, may have a protective role against tumor progression and angiogenesis. However, their effects on angiogenesis and the mechanism of their action against cancer progression remain elusive. This study aimed to investigate the effect of bioactive compounds of melon seed on the expression of angiogenesis genes in BALB/c mice with breast cancer. Material and methods: Trypsin inhibitor (TI) was purified from the seed powder of Cucumis melo. Half- maximal inhibitory concentration was determined for TI, extract of melon seed powder (EXT), and tamoxifen (TAM) by the (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) test. Also, breast tumor was induced by subcutaneous injection of MC4-L2 cells in BALB/c inbred mice breast tissue. After tumor growth, mice were treated with TI, EXT, and TAM to examine their effects on the tumor characteristics and expression of angiogenesis-related genes including MMP-2, MMP-9, and vascular endothelial growth factor (VEGF) using the reverse transcription polymerase chain reaction method. Results: Trypsin inhibitor, EXT, TAM, and adjuvant treatment of TI + TAM resulted a reduction in expression of MMP-2, MMP-9, and VEGF. All treatments improved the breast tumor characteristics and the necrosis. The real-time polymerase chain reaction method verified the positive effects of the treatments on the breast cancer cell line and tumors. Conclusions: The results indicated that treatments with TI purified from Cucumis melo seeds and also combination therapy of TI and TAM can be considered as an alternative therapy in breast cancer patients. Further studies are warranted.
RESUMEN
Studies have revealed that the timing of macronutrient ingestion may influence body weight and glucose tolerance. We aimed to examine the effect of high protein v. high carbohydrate intake at the evening meal on metabolic parameters of patients with type 2 diabetes. This is a single-blinded, parallel, randomised controlled trial. Ninety-six patients with type 2 diabetes, aged 32-65 years with a mean BMI of 28·5 (sd 3·4) kg/m2, were randomly assigned into one of these three groups: standard evening meal (ST), high-carbohydrate evening meal (HC) and high-protein evening meal (HP). Then, the patients were followed for 10 weeks. HbA1c, fasting blood glucose, fasting insulin, insulin resistance, TAG, LDL-cholesterol, VLDL-cholesterol, diastolic blood pressure, body weight, body fat percentage and waist circumference decreased significantly in all three groups (P < 0·05). HbA1c showed more improvement in the ST compared with the HP group (-0·45 (sd 0·36) v. -0·26 (sd 0·36)). Reductions in BMI and body weight were significantly higher in the ST compared with the HP group (P < 0·05). Reductions in total cholesterol, non-HDL-cholesterol and systolic blood pressure were significant in all groups, except for the HP group. Non-HDL-cholesterol:HDL-cholesterol remained unchanged in all groups. The results of the present study revealed that even distribution of carbohydrates and protein among meals compared with reducing carbohydrates and increasing protein at dinner may have a more beneficial effect on glycaemic control of patients with type 2 diabetes.

BACKGROUND: The role of dietary interventions in improving the symptoms of Multiple Sclerosis (MS) has always been considered, but few studies have been conducted in this area. This study aimed to investigate the effects of modified anti-inflammatory diet on fatigue, quality of life, and inflammatory markers among patients with Relapsing-Remitting Multiple Sclerosis (RRMS). METHODS: This randomized clinical trial was conducted on 100 patients with RRMS. The patients were randomly divided into the diet group (anti-inflammatory diet) or the control group (healthy diet recommendations) for 12 weeks. Fatigue and quality of life were assessed by Modified Fatigue Impact Scale (MFIS) and Multiple Sclerosis Quality of Life (MSQoL-54), respectively. Anthropometric measures and inflammatory biomarkers, including Interleukin 17 (IL-17), Interleukin 4 (IL-4), and high sensitivity C-Reactive Protein (hs-CRP), were assessed at baseline and end of the study. RESULTS: The results showed a significant improvement in MFIS as well as in physical and mental components of MSQoL-54 (p = 0.001, p = 0.015, and p = 0.003, respectively) in the diet group compared to the control group. The results also showed a significant increase in IL-4 level (p = 0.022). However, no significant changes were detected in IL-17 and hs-CRP levels (p = 0.091, 0.418, respectively). CONCLUSION: Modified anti-inflammatory diet could improve fatigue and quality of life and increase IL-4 level.

Background: Chronic obstructive pulmonary disease (COPD), as an airway limitation condition, is accompanied by alteration of muscle mass and function. We aimed to determine the relationship between disease severity and body composition, muscle function, and nutritional status in COPD patients. Methods: This cross-sectional study was conducted on 129 COPD participants. Muscle strength, body composition, and calf circumference (CC) were measured using a hydraulic hand dynamometer, bioelectrical impedance analysis (BIA), and a tape measure, respectively. Furthermore, fat-free mass index (FFMI), body mass index (BMI) and muscle mass value were calculated by equations. Forced expiratory volume in one second (FEV1) was assessed as well. Nutritional status was also evaluated by subjective global assessment (SGA) questionnaire. SPSS software (version 21 ) was used, chi-square, fisher's exact test, univariate and multivariate linear regression models were used for statistical analysis. P-values less than 0.05 were considered significant. Results: Based on FEV1 classification, 52.7% of the patients had severe conditions. The reports indicated that the prevalence of low CC was 54.2%, low muscle mass 38.7%, low FFMI 34.8%, low right handgrip strength 61.2% and low left handgrip strength 64.3%. Furthermore, there was an increasing trend based on FEV1 in low CC (p=0.032), low muscle mass (p=0.005), low FFMI (p=0.002), low right handgrip strength (p=0.004) and low left handgrip strength (p=0.014). The results of univariate analysis showed muscle mass (p=0.036), total protein (p=0.043), FFM (p=0.047), FFMI (p=0.007), SGA (p=0.029), right handgrip strength (p=0.004) and left hand grip strength (p=0.023) were associated with FEV1. In addition, the results of multivariate analysis demonstrated low values of FFMI (p=0.005) and right handgrip strength (p=0.042) were the main detrimental factors for FEV1. The results of multivariate analysis were confirmed by stepwise model. Conclusion: Low values of muscle mass and function are prevalent among COPD patients. The present study revealed that low FFMI and handgrip strength were closely related to disease severity.
RESUMEN
BACKGROUND: The development of effective nutritional supports for patients with chronic obstructive pulmonary diseases (COPD) is still challenging. This study was conducted to investigate the efficacy of daily consumption of fortified whey on inflammation, muscle mass, functionality, and quality of life in patients with moderate-to-severe COPD. METHODS: A single-blind, randomized trial study was performed on patients with COPD (n = 46). Participants in the intervention group (n = 23) daily received 250 ml of whey beverage fortified with magnesium and vitamin C for 8 weeks. Any changes in inflammatory cytokines (including interleukin- 6 (IL-6) and tumor necrosis factor (TNFα)) were the primary outcomes and the secondary outcomes were fat-free mass, handgrip strength, malnutrition, glutathione and malondialdehyde serum concentrations, and health-related quality of life (HRQoL). Body composition and muscle strength were measured by Bioelectrical Impedance Analysis (BIA) and hydraulic hand dynamometer, respectively. Fat-free mass index (FFMI) was also calculated. RESULTS: At the end of the study, 44 patients were analyzed. There were significant decreases in IL-6 concentrations in the intervention group compared to the control group. Also, FFMI, body protein, and handgrip strength increased significantly in the intervention group with significant changes between two groups. Moreover, improvement in health-related quality of life was observed in the intervention group compared to the control group. There were no significant changes in other study variables. CONCLUSIONS: This novel nutritional intervention decreased inflammatory cytokines levels, improved indices of skeletal muscle mass and muscle strength, and ultimately, increased HRQoL in patients with moderate-to-severe COPD. Thus, it is suggested to do further studies to assess the effects of nutrition intervention on COPD progression. TRIAL REGISTRATION: IR.SUMS.REC.1396.85 ( https://www.irct.ir/ ).

BACKGROUND: Recent studies have reported that herbal extracts may have some protective effect against the complications of diabetes mellitus. This study aimed to investigate the effects of Achillea millefolium hydroalcoholic extract in comparison to metformin on liver damage, lipid abnormality, and glycemic control in diabetic rats. METHODS: Rats were randomly assigned to 7 groups of 10 animals. Diabetes was induced by injection of streptozotocin (STZ) to 4 groups of rats. Three groups of diabetic rats were given 250 mg/kg/day metformin, 25 mg/kg/day Achillea millefolium hydroalcoholic extract, or 100 mg/kg/day of this extract. Two non-diabetic groups were also given either 25 mg/kg/day or 100 mg/kg/day Achillea millefolium extract. Normal control and diabetic control rats received 1 mL/day of normal saline. Treatments were administered through oral gavage for 28 days. At the end, rats were anesthetized with ether and their serum samples were separated in order to measure blood glucose, serum total protein, lipids, and liver enzymes. RESULTS: There was a significant reduction in blood glucose, serum liver enzymes, triglycerides, and total- and LDL-cholesterol levels of the Achillea millefolium extract-treated groups compared to the other groups. In addition, there was a significant increment in body weight and HDL-cholesterol serum level in the Achillea millefolium-treated groups. CONCLUSION: Achillea millefolium extract compared to metformin reduces lipid abnormality, blood glucose and liver enzymes in STZ-induced diabetic rats. Future clinical studies are warranted to confirm our experimental findings in humans.

BACKGROUND: Ulcerative colitis is an inflammatory disease with indefinite treatment. The present study aimed to assess the anti-inflammatory and antioxidant effects of Carum copticum L. (CC) extract on induced colitis in rats. METHODS: Sixty male rats were randomly divided into six groups (n=10 per group). Acetic acid-induced colitis rats were orally administered with doses of 100, 200, and 400 mg/kg CC extract, and 100 mg/kg sulfasalazine for seven consecutive days, respectively. Colonic biopsies were taken to measure histopathological parameters as well as the tumor necrosis factor (TNF-α), interleukin-6 (IL-6), myeloperoxidase (MPO), malondialdehyde (MDA), and glutathione (GSH). Data analysis was performed using the one-way ANOVA and Tukey's test for normally distributed data. Kruskal-Wallis test followed by Dunn's test was used for non-normally distributed data. The analysis was performed at P≤0.05 using SigmaStat software (version 10.0). RESULTS: The control colitis group had a significantly higher total colitis index (P=0.01), TNF-α (P=0.01), IL-6 (P=0.01), MPO (P=0.01), and MDA (P=0.01); and lower GSH (P=0.01) than those of the sham group. The colitis group receiving a dose of 200 mg/kg/day CC extract had a significantly lower total colitis index (P=0.01), TNF-α (P=0.01), IL-6 (P=0.01), MPO (P=0.01), and MDA (P=0.01); and higher GSH (P=0.01) than those of the control colitis group. The colitis group receiving a dose of 200 mg/kg/day CC extract had a significantly lower total colitis index (P=0.04), TNF-α (P=0.03), IL-6 (P=0.04), MPO (P=0.03), and MDA (P=0.03); and higher GSH (P=0.01) than those of the colitis group receiving sulfasalazine. CONCLUSION: The present study revealed that CC extract had healing effects on colitis, possibly due to its antioxidant and anti-inflammatory properties.
RESUMEN
The results of human clinical trials have revealed that the effects of resveratrol on adipokines are inconsistent. Our objective was to elucidate the role of resveratrol supplementation on adipokines through a systematic review and a meta-analysis of available randomized placebo-controlled trials (RCTs).1 The search included PubMed-MEDLINE, SCOPUS and ISI web of sciences database till up to 6th November 2016. Weight mean differences (WMD)2 were calculated for net changes in adipokines using fixed-effects or random-effects models; meta-regression analysis and publication bias were conducted in accordance with standard methods. Nine RCTs with 11 treatment arms were eligible for inclusion in this systematic review and meta-analysis. Meta-analysis of data from 10 treatment arms showed a significant change in plasma adiponectin concentrations following resveratrol supplementation (WMD: 1.10µg/ml, 95%CI: 0.88, 1.33, p<0.001); Q=11.43, I2=21.29%, p=0.247). There was a significant greater adiponectin-reducing effect in trials with higher than or equal to 100mg/day (WMD: 1.11µg/ml, 95%CI: 0.88, 1.34, p<0.001), versus those with less than 100 mg/day dosage (WMD: 0.84µg/ml, 95%CI: -0.62, 2.31, p=0.260). Meta-analysis of data from 5 treatment arms did not find any significant change in plasma leptin concentrations following resveratrol supplementation (WMD: 3.77ng/ml, 95% CI: -2.28, 9.83, p=0.222; Q=8.00, I2=50.01%). Resveratrol significantly improves adiponectin but does not affect leptin concentrations. Additional studies are required to further evaluate the potential benefits of resveratrol on adipokines in humans.

BACKGROUND: Malnutrition is an important factor in the survival of critically ill patients. The purpose of the present study was to assess the nutritional status of patients in the intensive care unit (ICU) on the days of admission and discharge via a detailed nutritional assessment. METHODS: Totally, 125 patients were followed up from admission to discharge at 8ICUs in Shiraz, Iran. The patients' nutritional status was assessed using subjective global assessment (SGA), anthropometric measurements, biochemical indices, and body composition indicators. Diet prescription and intake was also evaluated. RESULTS: Malnutrition prevalence significantly increased on the day of discharge (58.62%) compared to the day of admission (28.8%) according to SGA (P<0.001). The patients' weight, mid-upper-arm circumference, mid-arm muscle circumference, triceps skinfold thickness, and calf circumference decreased significantly as well (P<0.001). Lean mass weight and body cell mass also decreased significantly (P<0.001). Biochemical indices showed no notable changes except for magnesium, which decreased significantly (P=0.013). A negative significant correlation was observed between malnutrition on discharge day and anthropometric measurements. Positive and significant correlations were observed between the number of days without enteral feeding, days delayed from ICU admission to the commencement of enteral feeding, and the length of ICU stay and malnutrition on discharge day. Energy and protein intakes were significantly less than the prescribed diet (26.26% and 26.48%, respectively). CONCLUSION: Malnutrition on discharge day increased in the patients in the ICU according to SGA. Anthropometric measurements were better predictors of the nutritional outcome of our critically ill patients than were biochemical tests.
RESUMEN
OBJECTIVE: Depression is considered as the most common psychological problem in hemodialysis (HD) patients. As there is little evidence regarding the association of depression with serum selenium level as an antioxidant in these patients, the current survey investigates the possible relationship between depression and nutritional status including serum selenium levels. DESIGN: Cross-sectional study. SETTING AND SUBJECTS: A total of 110 HD patients and 40 healthy controls were enrolled in the study. The patients were in the age range of 18 to 85 years, who had been on hemodialysis for at least 3 months without any acute illness. MAIN OUTCOME MEASURE: Beck Depression Inventory was used for assessing the severity of depression. Malnutrition was evaluated through subjective global assessment (SGA) and malnutrition inflammation score (MIS). Serum selenium levels and routine laboratory markers were measured from fasting samples. RESULTS: Sixty-two percent of the patients had some degree of depression based on Beck Depression Inventory score. HD patients were considered to be selenium deficient after comparing the mean value of serum selenium between the patients and controls (P < .001). No significant difference was found in serum selenium levels between depressed HD patients and the rest of patients without depression. The mean level of SGA and MIS in the depressed patients was significantly higher than the rest of patients (P = .03 and P = .04, respectively). Also lower levels of hemoglobin and serum albumin were significantly seen in depressed patients compared with nondepressed ones (P = .004 and P = .04, respectively). CONCLUSIONS: Although the HD patients in this study were selenium deficient, no significant association was found between depression and selenium. In addition, depression was more prevalent in malnourished HD patients with higher SGA and MIS scores and lower serum albumin and hemoglobin levels.

OBJECTIVE: To assess the effects of Coenzyme Q10 supplementation on glycaemic control, oxidative stress and adiponectin levels in people with type 2 diabetes. METHODS: The randomised, single-blind, placebo-controlled study was conducted in the city of Shiraz, Iran, in 2012 and comprised type 2 diabetes subjects recruited from various health facilities. Subjects and controls received 100mg Coenzyme Q10 or placebo twice a day for eight weeks respectively. A variety of measurements were made at baseline and at the end of the intervention. These included measuring markers of glycaemic control (fasting blood glucose and glycated haemoglobin); a marker of oxidative stress (malondialdehyde); and an anti-inflammatory marker (adiponectin). SPSS 15 was used for statistical analysis. RESULTS: Of the 52 patients, 28(54%) were male and 24(46%) were female, with an overall mean age of 51.73±7.34 years. There were 16(62% male and 10(39%) females in the intervention group, and 12(46%) male and 14(54%) female subjects in the control group. Among the cases, Coenzyme Q10 resulted in a significant reduction in malondialdehyde levels (p=0.04). However, the difference within the controls for this factor was not significant (p>-0.05). Moreover, fasting blood glucose, glycated haemoglobin and adiponectin levels showed no significant differences within or between the groups (p>0.05 each). CONCLUSIONS: Coenzyme supplementation may reduce oxidative stress in type 2 diabetics. However, it may not have any effects on glycaemic control and adiponectin levels.

OBJECTIVES: To determine the prevalence of dyspepsia and its correlation with quality of life in Fars Qashqai Turkish migrating nomads from Southern Iran. METHODS: During 2010 we enrolled 397 Qashqai migrating nomads from Southern Iran who were 25 years of age or older. Participants completed a questionnaire that consisted of demographic factors, lifestyle data, gastrointestinal symptoms, and the Short-Form 36 Health Survey (SF-36) questionnaire. RESULTS: There was a 48% prevalence of dyspepsia symptoms among participants. The prevalence was higher among females, those less than 35 years of age, married participants, and those with a low body mass index (BMI). The correlation between dyspepsia and quality of life was significant. Dyspeptic patients were classified into ulcer-like (27.9%), dysmotility-like (26.2%), and unspecified (45.9%) groups. A significant correlation existed between dyspepsia symptoms and consumption of dairy products, drinking water and tea before and after meals, smoking, dysphagia, reflux, heartburn, and use of non-steroid anti-inflammatory drugs and acetaminophen. CONCLUSION: The high prevalence of dyspepsia in Qashqai nomads necessitates educational health programs for the migrating tribes in order to decrease prevalence of this disease.
RESUMEN
BACKGROUND: The dramatic increase in the incidence of diabetes and its associated complications require a natural and safe solution to control and delay such complications. The present study tested the hypothesis that probiotics may affect biochemical indices of diabetic patients Methods: Thirty four types 2 diabetic patients aged between 25 to 65 years, and diagnosed with diabetes for less than 15 years were selected for this single- blinded clinical trial. Using balanced block random sampling, the patients were divided into two groups of intervention (probiotics) and placebo. Blood samples tested for baseline glucose, insulin, TG, total cholesterol, LDL-C, HDL-C, malondialdehyde, high sensitive CRP (hs-CRP) and IL-6. After six weeks of experiment, fasting blood samples were re-tested and the data obtained were analyzed using SPSS software. RESULTS: There were no significant differences between anthropometric data including body mass index and waist to hip ratio in placebo and treatment groups. There was no significant difference in FBS, Serum TG concentration total cholesterol and LDL-C levels between placebo and treatment groups. HDL-C levels were slightly elevated after probiotic treatment, which were not statistically significant. Insulin, MDA and IL-6 levels were reduced and high sensitive CRP hs.CRP levels were elevated, although, not statistically significant. CONCLUSION: The result of this study indicates a non- significant declining trend in the level of TG, MDA and IL-6 and insulin resistance after consumption of probiotics.
RESUMEN
INTRODUCTION: Macro-algae products have been shown to ameliorate the metabolic disorders state. Thus, highlighting their function as supplementary therapeutic agents can be a novel strategy for clinical therapies. This systematic review and meta-analysis of clinical trials aimed to summarize the effect of macro-algae consumption on serum lipid profile, glycaemic control and anthropometric factors. METHODS: In this systematic review and meta-analysis, a comprehensive search was performed for relevant studies published up to May 2023. The Cochran's Q test and I-square (I2 ) tests were used to evaluate heterogeneity across the included studies. The meta-analysis was conducted using random-effects model (DerSimonian and Laird), and weighted mean difference (WMD) was considered as the pooled effect size. RESULTS: Out of 8602 papers in the initial screening, eight clinical trials with a total of 438 participants were included into this meta-analysis. The results indicated that macro-algae supplementation significantly decreased serum levels of total cholesterol (TC) (WMD = -6.7 mg/dL; 95% CI: -12.59, -0.80; item = 0.026) and low-density lipoprotein cholesterol (LDL-c) (WMD = -8.25 mg/dL; 95% CI: -15.38, -1.12; p-value = .023). There was an increase in level of high-density lipoprotein cholesterol (HDL-c) (WMD = 0.48 mg/dL; 95% CI: -2.05, 3.01; p-value = .71) which was not statistically significant. Macro-algae supplementation reduced body mass index (BMI) (WMD = -0.28 kg/m2 ; 95% CI: -0.96, 0.41; p-value = .426), weight (WMD = -0.39 kg; 95% CI: -3.6, 2.83; p-value = .81), waist circumference (WC) (WMD = -0.52 cm; 95% CI: -2.71, 1.66; p-value = .64), fasting blood sugar (FBS) (WMD = -1.95 mg/dL; 95% CI: -5.19, 1.28; p-value = .24) and HbA1c (WMD = -0.02%; 95% CI: -0.14, 0.09; p-value = .66) in intervention group. CONCLUSIONS: This meta-analysis indicated that macro-algae supplementation significantly decreased TC and LDL-c level. It can also increase HDL-c level and reduce anthropometric indices and glycaemic control factors.

An insufficient intake of magnesium may be associated with the development of chronic obstructive pulmonary disease (COPD). We aimed to determine the relationship between health related quality of life (QoL), anthropometric indices and nutritional status with dietary magnesium intake in COPD patients. Sixty-one COPD patients participated in this cross-sectional study. QoL and nutritional status were assessed. Furthermore, body composition, calf circumference, and muscle strength were measured; equations were used to calculate fat-free mass index, body mass index, and muscle mass value. Dietary magnesium intake was assessed by three 24-hours recalls and magnesium intake was categorized as ≤ 188.08 mg/day (A group) and > 188.08 mg/day (B group). The χ2, independent-sample t-test and Mann-Whitney test were used for statistical analysis. The p values less than 0.05 were considered significant. Of QoL assessments the total and impact mean scores of St. George's respiratory questionnaire in the B group were significantly lower than the means of the A group (p value = 0.007 and 0.005, respectively). The instrumental activity of daily living score was significantly improved in patients with higher consumption of dietary magnesium (p = 0.02). Participants had a significantly lower mean score of patient-generated subjective global assessment in the B group compared to the A group (p = 0.003). Higher intake of dietary magnesium can lead to improve QoL and nutrition status.
RESUMEN
BACKGROUND/OBJECTIVES: Patients with diabetes mellitus have a lower quality of life and sleep compared with healthy individuals. Nutrition therapy has an important role in the management of diabetes and can improve inflammation and quality of life in patients with diabetes. The present study aimed to evaluate the effect of high-protein versus high-carbohydrate intake during evening meal on quality of life, sleep quality, inflammation, and oxidative stress in subjects with type 2 diabetes. SUBJECTS/METHODS: This is a 10-week randomized controlled trial. 96 adult patients with type 2 diabetes were assigned into one of the following three groups: standard evening meal (ST), high-carbohydrate evening meal (HC), and high-protein evening meal (HP). The effect of these diets was examined on high-sensitivity C-reactive protein, malondialdehyde, quality of life, and sleep quality. RESULTS: Sleep quality improved significantly in all groups (p < .05). The quality of life and high-sensitivity C-reactive protein improved in all groups except for the HP group (p < .05). Serum malondialdehyde level did not change significantly throughout the study (p > .05). CONCLUSIONS: Small manipulation of protein and carbohydrate distribution among the meals might not affect sleep quality. A diet with an even distribution of macronutrients among the meals or with a higher percentage of carbohydrates in the evenings can improve the quality of life and reduce inflammation in patients with type 2 diabetes, while a diet with a higher percentage of protein in the evenings may not improve it.
