RESUMO

Aging is a biological process with high susceptibility to several infections. This risk increases in older patients in residential care facilities (RCF). Thus, there is a clear demand for developing preventive interventions with new therapeutic compounds that combine efficacy and safety. This could be the case of compounds derived from plants of the genus Allium spp. The purpose of this study was to evaluate the impact of a combination of a garlic and onion extract concentrate standardized in organosulfur compounds derived from propiin on the incidence of respiratory tract infections in elderly patients of RCF. Sixty-five volunteers were selected at random to receive a placebo or a single daily dose of the extract for thirty-six weeks. Different clinical visits were performed to evaluate the main respiratory diseases with an infectious origin, as well as the associated symptoms and their duration. The extract showed a clinical safety profile and significantly reduced the incidence of respiratory infections. Moreover, the treatment decreased the number and duration of the associated symptoms compared with the placebo group. For the first time, we demonstrated the protective effect of Alliaceae extract in respiratory infectious diseases in elderly healthy volunteers, which could be used prophylactically against the most common infectious respiratory diseases.

RESUMO

Dietary changes affect the composition and structure of gut microbiota (GM) in animals and humans. One of the beneficial effects of consuming products derived from plants is the positive influence on immunity and gastrointestinal health. Species belonging to the genus Allium contain many organosulfur compounds (OSCs) that have been widely studied showing their biological properties and beneficial effects on intestinal health and GM. This is the first systematic review of OSCs from Allium performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, and it is based on the evidence that we found in literature about the benefits on the GM and intestinal health demonstrated by OSCs from Allium, and specifically from onion. OSCs from Allium cepa have shown a significant antibacterial activity against a broad spectrum of antibiotic-resistant Gram-positive and Gram-negative bacteria. In addition, the intake of OSCs from onion was able to modulate the composition of GM, increasing the beneficial bacterial populations in animal models. Moreover, the beneficial effects observed in murine models of colitis suggest that these compounds could be suitable candidates for the treatment of inflammatory bowel disease (IBD) or reverse the dysbiosis caused by a high-fat diet (HFD). Despite the evidence found both in vitro and in vivo, we have not found any article that tested OSCs different from allicin in clinical trials or dietary intervention studies in humans. In this sense, it would be interesting to conduct new research that tests the benefits of these compounds in human GM.

RESUMO

Hydroxytyrosol (HT) from olives and polyphenols from almond skin (ASPs) possess cardioprotective properties. This pilot study evaluates the effect of supplementation with a combination of olive fruit and almond skin extracts on low-density lipoprotein (LDL) cholesterol oxidation, lipid homeostasis, and inflammatory parameters in adults with moderate hypercholesterolemia. A randomized, parallel, double-blind, placebo-controlled pilot study of 8 weeks was performed. The extract group (EG) received the supplement with 7.5 mg HT +210 mg ASPs, and the control group (CG) received a placebo composed of maltodextrin. Oxidized LDL (oxLDL) levels and the oxLDL/LDL ratio were lower in the EG than in the CG after 8 weeks of treatment (18.76 ± 3.91 vs. 10.34 ± 4.22, P < .001 and 0.151 ± 0.025 vs. 0.08 ± 0.023, P < .001, respectively). Interleukin-1ß levels were significantly higher in the CG than in the EG at week 4 (P = .004), IL-6 was significantly higher in the CG than in the EG at week 4 (P = .049), and IL-10 was significantly increased at week 4 in both groups (P = .002 for CG and P = .001 for EG). In conclusion, daily consumption of a combination of an olive fruit extract and an almond skin extract for 8 weeks seems to protect LDL from oxidation and to prevent inflammatory status in moderately hypercholesterolemic subjects.

RESUMO

The aim of this study was to evaluate the effect of two doses of d-chiro-inositol (DCI) in combination with Myo-inositol (MYO) on the oocyte quality (OQ) of women with polycystic ovarian syndrome (PCOS) undergoing intracytoplasmic sperm injection (ICSI). Methods: This was a controlled, randomized, double-blind, parallel group study on 172 oocytes from 11 women. The study compared the effect of two MYO-DCI formulations given over 12 weeks on OQ. Five women received 550 mg of MYO + 300 mg of DCI daily (high DCI content group), while 6 women were given a daily dose of 550 mg of MYO with the only 27.6 mg of DCI (low DCI content group). Results: According to a multivariate analysis using linear mixed effect models, high doses of DCI have a positive influence on the quality of the cytoplasm of the oocyte (ß = 1.631, χ2 = 7.347, d.f. = 1, p = .00672). Zona pellucida, plasma membrane, cytoplasm, and sperm reception have also been improved with any combination of MYO/DCI by decreasing testosterone or improving insulin sensitivity, regardless of age and body mass index. Conclusion: The combination of MYO with high doses of DCI improved oocyte cytoplasm quality in women with PCOS undergoing ICSI.

RESUMO

BACKGROUND: Milk products fortified with vitamin D may constitute an alternative to pharmacological supplements for reaching the optimal levels of serum 25-hydroxyvitamin D [25(OH)D]. Our aim was to analyze the response of serum 25(OH)D and its predictive factors in postmenopausal healthy women after a dietary intervention with a milk fortified with vitamin D and calcium. METHODS: We designed a prospective study including 305 healthy postmenopausal women who consumed a fortified milk with calcium (900 mg/500 mL) and vitamin D3 (600 IU/500 mL) daily for 24 months. RESULTS: The 25(OH)D concentrations at 24 months were correlated to weight, to body mass index, to the percentage of fat, triglycerides and to baseline 25(OH)D levels. We found significant differences in the levels of 25(OH)D at 24 months according to baseline 25(OH)D levels (p < 0.001) and body mass index (p = 0.019) expressed at quartiles. Multivariate analysis showed an association between levels of 25(OH)D after the intervention and at baseline 25(OH)D (Beta = 0.47, p < 0.001) and percentage of body fat (Beta = -0.227, p = 0.049), regardless of the body mass index. CONCLUSIONS: In healthy postmenopausal women, the improvement in 25(OH)D after an intervention with a fortified milk for 24 months depends mainly on the baseline levels of serum 25(OH)D and on the percentage of body fat.

RESUMO

The purpose of this study was to evaluate the effect of two doses of D-chiro-inositol (DCI) in combination with Myo-inositol (MYO) in women with PCOS undergoing ICSI. This was a multicenter controlled, randomized, double-blind parallel group study with two MYO-DCI formulations for 12 weeks. The study group (SG) was administered 550 mg of MYO + 150 mg of DCI twice daily; the control group (CG) was administered 550 mg of MYO + 13.8 mg of DCI twice daily. The participants comprised 60 women with PCOS undergoing ICSI. At baseline, no differences were found between the two groups regarding age, BMI, HOMA-IR or testosterone levels. The pregnancy and live birth rates were significantly higher in the SG than in the CG (65.5 vs. 25.9 and 55.2 vs. 14.8, respectively) [risk ratio (RR) = 0.4; 95%CI (0.2, 0.79); p = .003 and RR = 0.27; 95%CI (0.10, 0.70); p = .002 respectively]. The risk of ovarian hyperstimulation syndrome (OHSS) was lower in the SG (3.44 vs. 18.5%, p = .07). The combination of MYO-DCI at high doses of DCI improves the pregnancy rates and reduces the risk of OHSS in women with PCOS undergoing ICSI.

RESUMO

BACKGROUND: Micronutrients such as vitamins and minerals and long-chain polyunsaturated omega-3 fatty acids (PUFAs) are essential for children's brain development and cognitive functions. The current study investigated whether milk fortified with micronutrients and PUFA can result in improved cognitive function in mainstream school children. METHODS: One-hundred-and-nineteen children (age 8-14, 58 boys) were randomly allocated to a fortified milk group or a regular full milk control group. Participants consumed 0.6L/day of the milk for 5 months. We recorded relevant biochemical, anthropometric, and cognitive measures (working memory and processing speed) at the start of the study and at follow-up after 5 months. RESULTS: The fortified milk significantly increased docosahexaenoic acid (DHA) (change from baseline of 28% [95% CI 17-39%] vs. -6% [95% CI - 13 to 0%] in the control group) and serum 25OH-vitamin D concentrations (41% [95% CI 30-52%] vs. 21% [95% CI 11-30%] in the control group). The fortified milk improved working memory on one of two tests (32% [95% CI 17-47%] vs. 13% [95% CI 6-19%] in the control group). The fortified milk also indirectly increased processing speed on one of two tests; this effect was small and completely mediated by increases in 25OH-vitamin D concentrations. CONCLUSIONS: These results suggest that fortifying milk with micronutrients and PUFA could be an effective and practical way to aid children's cognitive development.

RESUMO

PURPOSE: Elderly people are particularly vulnerable to seasonal influenza. Therefore, vaccination is strongly recommended. However, the vaccine efficacy is lower in the elderly, owing to immunosenescence. The objective of the present study was to evaluate the ability of the probiotic strain Lactobacillus coryniformis K8 CECT5711 to enhance the immune response to the influenza vaccine in the elderly and to assess the effects on symptoms related to respiratory infections. METHODS: A randomized, double-blind, placebo-controlled trial was conducted between November 2015 and April 2016. A total of 98 nursing home residents, more than 65 years of age were randomly assigned to receive L. coryniformis K8 CECT5711 (3 × 109 CFU/day) or a placebo for 2 weeks before influenza vaccination. The primary outcome was the percentage of seroconversion. The secondary outcomes were the incidence of influenza-like illness (ILI) and respiratory symptoms associated with respiratory infections during the 5-month follow-up period. The serum cytokine and immunoglobulin levels were also evaluated. RESULTS: The percentage of responders to vaccination was higher in the probiotic group than in the control group (p = 0.036). L. coryniformis ingestion was associated with a significantly lower incidence of respiratory symptoms commonly associated with respiratory infections (p = 0.007) and lower consumption of analgesics (p = 0.008). CONCLUSION: The administration of L. coryniformis K8 CECT5711 to an elderly population increased the immune response against the influenza vaccine and decreased symptoms associated with respiratory infections. Probiotic administration may be a natural and safe strategy to improve the efficacy of vaccines and to protect against common respiratory infections in susceptible populations.

RESUMO

OBJECTIVE: To determine the effect of the daily intake of calcium and vitamin D-enriched milk (with or without fructooligosaccharides [FOS]) on vitamin D, bone metabolism, and cardiovascular risk factors. MATERIALS AND METHODS: Two-year randomized controlled study, including 500 healthy postmenopausal women, assigned to 500 mL/day of skimmed milk to one of three groups: Low-dose (L): (120 mg/100 mL calcium, vitamin D3 30 UI/100 mL), group A: calcium and vitamin D (180 mg/100 mL and 120 UI/100 mL), and group B: calcium and vitamin D (180 mg/100 mL and 120 UI/100 mL) and FOS (5 g/L). We evaluated serum 25(OH)D, bone mineral density (BMD) by Dual Energy X-ray Absorptiometry, and biochemical data of glucose and lipid metabolism. RESULTS: After 24 months, vitamin D concentrations did not change in the control group, but increased in group A and group B, p < 0.001. We observed an increase in femoral neck BMD and an improvement in fasting plasma glucose, HbA1c, total cholesterol, low-density lipoprotein cholesterol, and apolipoprotein B 100. CONCLUSIONS: Daily intake of milk enriched with calcium and vitamin D in postmenopausal healthy women induces a significant improvement in vitamin D status, a significant increase in BMD at femoral neck, and also favorable effects on glucose and lipid profile.

RESUMO

OBJECTIVE: Defining the etiology of dental caries is a complex problem. The microbiological approach has included Streptococcus mutans as one of the bacterial species involved in this disease. This research investigates the inhibitory effects of heat-inactivated Lactobacillus salivarius CECT 5713 against S. mutans using in vitro and in vivo assays. DESIGN: On the one hand, the effect of non-viable L. salivarius CECT 5713 on the in vitro adhesion of S. mutans to hydroxyapatite discs was evaluated. On the other hand, levels of Streptococcus mutans, amount of salivary flow and salivary pH before and after taking the rinse with the non-viable L. salivarius CECT 5713 in healthy volunteers were assessed (self-controlled open-label pilot study). RESULTS: The levels of S. mutans seemed to decrease in the in vitro and in vivo assays (p<0.05). The in vitro effect of non-viable L. salivarius was maintained until 36 months of storage. In addition, the reduction of S. mutans salivary concentration in the volunteers was statistically significant from the third day until two weeks of treatment. CONCLUSIONS: Heat-inactivated L. salivarius CECT 5713 prevents S. mutans adhesion to hydroxyapatite and could be used as a strategy to reduce the salivary concentration of this oral pathogen.

RESUMO

Hydroxytyrosol (HT) is a main phenolic component of olive oil. In this study, we investigated the safety and effects produced by HT purified (99.5%) from olive mill waste. HT was administered at a daily dosage of 45mg for 8 weeks to volunteers with mild hyperlipidemia (n=14). We measured markers of cardiovascular disease risk, enzyme markers of several clinical conditions, hematology, antioxidant parameters, vitamins and minerals at baseline (T0), 4 weeks (T4) and 8 weeks (T8). The values obtained at T4 and T8 were compared with baseline. We found that the HT dose administered was safe and mostly did not influence markers of cardiovascular disease, blood lipids, inflammatory markers, liver or kidney functions and the electrolyte balance. Serum iron levels remained constant but a significant (P<0.05) decrease in ferritin at T4 and T8 was found. Serum folate and red blood cell folate levels were also reduced at T4 and T8. Finally, vitamin C increased by two-fold at T4 and T8 compared with levels at baseline. These results indicate a physiologically relevant antioxidant function for HT through increasing endogenous vitamin C levels.

RESUMO

INTRODUCTION: Recent results indicate that human mastitis and painful breastfeeding may be characterized by a mammary bacterial dysbiosis, a process in which the population of potential pathogens increases at the expense of the normal mammary microbiota. The objective of the present study is the evaluation of three different doses of Lactobacillus fermentum CECT5716 to reduce the load of Staphylococcus in the breastmilk of women suffering from painful breastfeeding. MATERIALS AND METHODS: A randomized double-blinded controlled study with four study groups was performed. Three groups received the probiotic strain for 3 weeks at doses of 3×10(9) colony-forming units (CFU)/day, 6×10(9) CFU/day, or 9×10(9) CFU/day. The fourth group received a placebo of maltodextrin. The main outcome of the study was Staphylococcus counts in breastmilk. The secondary outcomes were Streptococcus, Lactobacillus, and total bacteria counts in breastmilk, immunoglobulin A and interleukin 8 concentrations in breastmilk, and breast pain scores. RESULTS: At the end of the study, a significant decrease in the Staphylococcus load was observed in the probiotic groups compared with the baseline loads (p=0.045), whereas the control group maintained similar levels over time. A significant difference in the pain score was observed among the groups receiving the three probiotic doses compared with the control group (p=0.035, p=0.000, and p=0.028, respectively). A dose-response effect could not be observed because the three doses tested induced similar effects, and no significant differences were detected. CONCLUSIONS: We conclude that L. fermentum CECT5716 is an efficient treatment for breast pain during lactation associated with a high level of Staphylococcus in breastmilk.

RESUMO

OBJECTIVE: The association of dairy food consumption with the risk for developing cardiovascular disease (CVD) has been investigated in many studies, but results often have been contradictory. The aim of the present study was to determine whether genetic polymorphisms are associated with interindividual variation in the response of CVD risk biomarker values after milk consumption. METHODS: Fourteen single nucleotide polymorphisms (SNPs) in nine genes related to lipid metabolism were examined in 161 volunteers randomly allocated to consume either 500 mL/d of skimmed (S) or semi-skimmed (SS) milk for 1 year in addition to their usual diets. Total cholesterol/high-density lipoprotein cholesterol (TC/HDL-C) and low-density lipoprotein/HDL-C ratios were used as biomarkers of CVD risk. Three-way repeated-measures analysis of variance was used to examine the effect of time, treatment (S or SS), and genotype on these biomarkers. RESULTS: A TT genotype for the proliferator-activated receptor alpha polymorphism (PPARA rs135549 SNP) was significantly associated with a reduction in the TC/HDL and LDL/HDL ratios after 12 mo of S milk intake (mean reduction -0.29, 95% confidence interval [CI], -0.63 to 0.05; P = 0.0015 and -0.31, 95% CI, -0.58 to -0.03; P = 0.0005, respectively). However, no differences were observed after consuming either S or SS milk in the C allele carriers. CONCLUSIONS: Saturated fatty acid consumption has long been linked to an increased risk for CVD; indeed, the consumption of saturated fat-free products is recommended as a means of reducing this risk. However, the present results suggest that many individuals might not benefit from such general recommendations. Genetic analysis of PPARA rs135549 might help identify those individuals who are more likely to benefit from reducing the saturated fatty acid content of their diet.

RESUMO

The hypothesis of this study was that the replacement of regular milk with fortified milk in hyperlipidemic adults for 1 year would improve bone biomarkers. The fortified milk contained eicosapentaenoic acid and docosahexaenoic acid from fish oils, oleic acid, vitamins A, B(6), and E, as well as folic acid. We believe that the fortified milk will improve the blood fatty acid profile and vitamin status in subjects to benefit bone health biomarkers. From the 84 patients who accepted to participate, 11 of these were excluded for the presence of metabolic diseases and 1 was excluded for noncompliance with the protocol. Seventy-two hyperlipidemic patients (35-65 years) were randomly divided between 2 study groups. The supplement group (E; n = 39) consumed 0.5 L/d of fortified milk that contained fish oil, oleic acid, and vitamins. The control group (C; n = 33) consumed 0.5 L/d of semiskimmed milk containing the same amount of total fat. Blood samples were taken at T(0), T(3), T(6), and T(12) months to determine plasma fatty acids, vitamins B(6), E, and 25-hydroxyvitamin D and serum folate, calcium, soluble osteoprotegerin (OPG), soluble receptor activator of NF-kappaB ligand (RANKL), osteocalcin, parathormone, type I collagen carboxy-terminal telopeptide, and malondialdehyde. After 1 year, the E group showed a significant increase in plasma eicosapentaenoic acid (42%), docosahexaenoic acid (60%), vitamin B6 (38%), OPG (18%), RANKL (7%), OPG/RANKL (10%), red blood cell folate (21%), serum folate (53%), calcium (4%), vitamin D (11%), and osteocalcin (22%). Dietary supplementation with the fortified milk drink improved nutritional status and bone formation markers in adult hyperlipidemic patients.

RESUMO

There is growing interest in the health effects of olive oil polyphenols, particularly hydroxytyrosol (HT), for their potential application in the treatment of inflammatory conditions such as cardiovascular disease (CVD). As oxidative modification of low-density lipoproteins (LDL) plays a central role in the development of CVD, natural antioxidants are a main target for the nutraceutical industry. In this study we firstly investigated the absorption of pure hydroxytyrosol (99.5%) administered as a supplement in an aqueous solution (2.5mg/kg BW) in the plasma and urine of healthy volunteers (n=10). Plasma C(max) for HT and homovanillic alcohol (HvOH) were detected at 13.0+/-1.5 and 16.7+/-2.4min, respectively. The HT and HvOH levels were undetectable 2-h after the administration. HT, HvOH, homovanillic acid and 3,4-dihydroxyphenylacetic acid were found as free forms (44%) or as glucuronide (34.4%) or sulphate (21.2%) conjugates in the 24-h urine samples of the subjects. In a second phase of the study, the same amounts of HT were administered to the subjects and the presence of HT in purified plasma lipoproteins was investigated in LDL fractions freshly isolated. 10min after the ingestion of the HT supplement, more than 50% of the total amount detected was present in the LDL-purified fractions and its concentration declined in accordance with its presence in plasma but no changes were found in total antioxidant capacity, malondialdehyde or LDL lag time. These results indicate that pure HT transiently associates with LDL lipoproteins in vivo.

OBJECTIVE: The main goal of the present study was to evaluate the effect of a commercially available milk containing small amounts of eicosapentaenoic acid and docosahexaenoic acid, oleic acid, and vitamins A, B6, D, E, and folic acid compared with semi-skimmed and skimmed milk in volunteers with moderate cardiovascular risk. METHODS: Two hundred ninety-seven subjects 25 to 65 y of age with moderate cardiovascular risk were randomly allocated into three groups. In addition to their diets, one group consumed 500 mL/d of the enriched milk, another group consumed 500 mL/d of skimmed milk, and a control group consumed 500 mL/d of semi-skimmed milk. All groups consumed the dairy drinks for 1 y and blood samples were taken at 0 and 12 mo. RESULTS: Consumption of enriched milk for 1 y produced significant (P < 0.05) increases in serum folate (58%) and high-density lipoprotein cholesterol (4%). Plasma triacylglycerols (10%), total cholesterol (4%), and low-density lipoprotein cholesterol (6%) were reduced significantly only in the supplemented group. Serum glucose, homocysteine, and C-reactive protein remained unchanged. In the skimmed milk and semi-skimmed milk groups, the only significant decreases were in serum folate (17% and 11%, respectively). CONCLUSION: Daily intake of a milk enriched with fish oil, oleic acid, and vitamins improved the nutritional status and cardiovascular risk markers of volunteers, whereas skimmed milk and semi-skimmed milk did not.

RESUMO

OBJECTIVE: We studied the coadjuvant capability of oral consumption of the breast-milk-isolated strain Lactobacillus fermentum (CECT5716) for an anti-influenza vaccine. METHODS: A randomized, double-blinded, placebo-controlled human clinical trial including 50 volunteers (31 male and 19 female) was performed to address the immunologic effects of an intramuscular anti-influenza vaccine in adults (33.0 +/- 7.7 y old). Fifty percent of volunteers received an oral daily dose of methylcellulose (placebo) or probiotic bacteria (1 x 10(10) colony-forming units/d) 2 wk before vaccination and 2 wk after vaccination. RESULTS: Two weeks after vaccination there was an increase in the proportion of natural killer cells in the probiotic group but not in the placebo group. The vaccination induced an increase in T-helper type 1 cytokine concentrations and in T-helper and T-cytotoxic proportions in both groups; however, the probiotic group showed a significant higher induction in some of these parameters. Regarding the humoral effects, induction of antibody response in the placebo group could not be detected. In the case of the probiotic group, a significant increase in antigen specific immunoglobulin A was detected. Although an increase in total immunoglobulin M was observed, changes in anti-influenza antigen specific immunoglobulin M were not observed. The incidence of an influenza-like illness during 5 mo after vaccination (October to February) was lower in the group consuming the probiotic bacteria. CONCLUSION: Oral administration of the strain L. fermentum CECT5716 potentates the immunologic response of an anti-influenza vaccine and may provide enhanced systemic protection from infection by increasing the T-helper type 1 response and virus-neutralizing antibodies.

RESUMO

Certain nutrients have been shown to be effective in preventing coronary heart disease. We hypothesized that a daily intake of low amounts of a number of these nutrients would exert beneficial effects on risk factors and clinical variables in patients that suffered from myocardial infarction (MI) and were following a cardiac rehabilitation program. Forty male MI patients were randomly allocated into 2 groups. The supplemented group consumed 500 mL/d of a fortified dairy product containing eicosapentaenoic acid, docosahexaenoic acid, oleic acid, folic acid, and vitamins A, B-6, D, and E. The control group consumed 500 mL/d of semi-skimmed milk with added vitamins A and D. The patients received supervised exercise training, lifestyle and dietary recommendations, and they were instructed to consume the products in addition to their regular diet. Blood extractions and clinical examinations were performed after 0, 3, 6, 9, and 12 mo. Plasma concentrations of eicosapentaenoic acid, docosahexaenoic acid, oleic acid, folic acid, vitamin B-6, and vitamin E increased after supplementation (P<0.05). Plasma total and LDL-cholesterol, apolipoprotein B, and high-sensitivity C-reactive protein concentrations decreased in the supplemented group (P<0.05), and plasma total homocysteine decreased in both groups. There were no changes in heart rate, blood pressure, or cardiac electrocardiographic parameters in either group. Therapeutic lifestyle changes, effected through a CR program comprising regular exercise and the intake of a combination of dietary nutrients, reduced a variety of risk factors in MI patients, which supports the rationale for nutritional programs in the secondary prevention of coronary heart disease.
