2007-01-01
The U.S. Department of Energy (DOE) has conducted interim groundwater remedial activities on the Hanford Site since the mid-1990s for several groundwater contamination plumes. DOE established the Columbia River Protection Supplemental Technologies Project (Technologies Project) in 2006 to evaluate alternative treatment technologies. The objectives for the technology project are as follows: develop a 300 Area polyphosphate treatability test to immobilize uranium, design and test infiltration of a phosphate/apatite technology for Sr-90 at 100-N, perform carbon tetrachloride and chloroform attenuation parameter studies, perform vadose zone chromium characterization and geochemistry studies, perform in situ biostimulation of chromium studies for a reducing barrier at 100-D, and perform a treatability test for phytoremediation for Sr-90 at 100-N. This document provides the quality assurance guidelines that will be followed by the Technologies Project. This Quality Assurance Project Plan is based on the quality assurance requirements of DOE Order 414.1C, Quality Assurance, and 10 CFR 830, Subpart A--Quality Assurance Requirements as delineated in Pacific Northwest National Laboratory?s Standards-Based Management System. In addition, the technology project is subject to the Environmental Protection Agency (EPA) Requirements for Quality Assurance Project Plans (EPA/240/B-01/003, QA/R-5). The Hanford Analytical Services Quality Assurance Requirements Documents (HASQARD, DOE/RL-96-68) apply to portions of this project and to the subcontractors. HASQARD requirements are discussed within applicable sections of this plan.

[Quality control in herbal supplements].
Oelker, Luisa
2005-01-01
Quality and safety of food and herbal supplements are the result of a whole of different elements as good manufacturing practice and process control. The process control must be active and able to individuate and correct all possible hazards. The main and most utilized instrument is the hazard analysis critical control point (HACCP) system the correct application of which can guarantee the safety of the product. Herbal supplements need, in addition to standard quality control, a set of checks to assure the harmlessness and safety of the plants used.

Full Text Available The aim of the study was to evaluate the effect of different feed additives (bee pollen extract, propolis extract, and probiotic on meat quality of broiler chickens. A total of 180 one day-old broiler chicks of mixed sex (Ross 308 were randomly divided into 3 groups. Dietary treatments were as follows: basal diet, free of supplements (control group; C; basal diet plus 400 mg bee pollen extract per 1 kg of feed mixtures and 3.3 g probiotic preparation added to drinking water (group E1; basal diet plus 400 mg propolis extract per 1 kg of feed mixtures and 3.3 g probiotic preparation added to drinking water (group E2. In the experiment, the probiotic preparation based on Lactobacillus fermentum (1.109 CFU.g-1 of bearing medium was used. Fattening period lasted for 42 days. Feed mixtures were produced without any antibiotic preparations and coccidiostatics. Meat quality was evaluated by following technological properties: cooling, freezing and roasting loss; colour parameters based on CIELab system; and shear force. Both dietary supplementations led to decrease in cooling (p ≤0.05 and freezing (p ≥0.05 losses compared with control. On the contrary, the supplemented diet tended to increase roasting losses (p ≤0.05 and shear force values in thigh muscle (p ≤0.05. Significantly higher L* values (p ≤0.05 in breast and thigh muscles, as well as the b* values in thigh muscle, were found when broiler chickens were fed the supplements, especially bee pollen extract and probiotics. In addition, the supplements improve redness (a* of meat. The redness of breast muscle appeared to be the most affected (p ≥0.05 by propolis extract plus probiotics supplementation, while thigh muscle had the highest value (p ≤0.05 in bee pollen extract plus probiotics supplemented group. These findings suggested that the supplements have a beneficial effect on quality of chicken meat due to positive changes in most of quality indicators investigated in the

MICROBIOLOGICAL QUALITY OF FOOD SUPPLEMENTS.
Ratajczak, Magdalena; Kubicka, Marcelina M; Kamińska, Dorota; Długaszewska, Jolanta
2015-01-01
Many specialists note that the food offered today - as a result of very complex technological processing - is devoid of many components that are important for the organism and the shortages have to be supplemented. The simplest for it is to consume diet supplements that provide the missing element in a concentrated form. In accordance with the applicable law, medicinal products include all substances or mixtures of substances that are attributed with properties of preventing or treating diseases with humans or animals. Permits to admit supplements to the market are issued by the Chief Sanitary Inspector and the related authorities; permits for medicines are issued by the Chief Pharmaceutical Inspector and the Office for Registration of Medicinal Products, Medical Devices and Biocidal Products. Therefore, admittance of a supplement to the market is less costly and time consuming_than admittance of a medicine. Supplements and medicines may contain the same component but medicines will have a larger concentration than supplements. Sale of supplements at drug stores and in the form of tablets, capsules, liquids or powders makes consumer often confusing supplements with medicines. Now there are no normative documents specifying limits of microbiological impurities in diet supplements. In Polish legislation, diet supplements are subject to legal acts concerning food. Medicines have to comply with microbiological purity requirements specified in the Polish Pharmacopeia. As evidenced with the completed tests, the proportion of diet supplement samples with microbiological impurities is 6.5%. Sales of diet supplements have been growing each year, they are consumed by healthy people but also people with immunology deficiencies and by children and therefore consumers must be certain that they buy safe products.

Proteomics in quality control: Whey protein-based supplements.
Garrido, Bruno Carius; Souza, Gustavo H M F; Lourenço, Daniela C; Fasciotti, Maíra
2016-09-16
The growing consumption of nutritional supplements might represent a problem, given the concern about the quality of these supplements. One of the most used supplements is whey protein (WP); because of its popularity, it has been a target of adulteration with substitute products, such as cheaper proteins with lower biological value. To investigate this type of adulteration, this study used shotgun proteomics analyses by MS(E) (multiplexed, low- and high-collision energy, data-independent acquisition) of WP-based supplements. Seventeen WP-based supplement samples were evaluated. Chicken, maize, rice, potato, soybean, and wheat proteins were considered as probable sources of bovine whey adulteration. Collectively, 523 proteins were identified across all 16 samples and replicates, with 94% of peptides inside a normal distribution within 10ppm of maximum error. In 10 of the 16 samples analyzed, only proteins from bovine whey could be detected, while in the other samples several other protein sources were detected in high concentrations, especially soybean, wheat, and rice. These results point out a probable adulteration and/or sample contamination during manufacturing that could only be detected using this proteomic approach. The present work shows how shotgun proteomics can be used to provide reliable answers in quality control matters, especially focusing on Whey Protein nutritional supplements which are a very popular subject in food and nutrition. In order to achieve an appropriate methodology, careful evaluation was performed applying extremely rigorous quality criteria, established for the proteomic analysis. These criteria and the methodological approach used in this work might serve as a guide for other authors seeking to use proteomics in quality control. Copyright © 2016 Elsevier B.V.

2015-02-01
Full Text Available Many national and international public health organisations recommend achieving nutrient adequacy through consumption of a wide variety of nutritious foods. Despite this, dietary supplement sales continue to increase. Understanding the characteristics of micronutrient supplement users and the relationship with diet quality can help develop effective public health interventions to reduce unnecessary consumption of vitamin and mineral supplements. Participants (n = 1306 were a convenience sample of students studying first year food and nutrition. Data was collected via a Food and Diet Questionnaire (FDQ and a Food Frequency Questionnaire (FFQ. Supplement users were defined as participants who indicated consuming any listed supplement as frequently as once a month or more. Diet quality was assessed using a Dietary Guideline Index (DGI score. Prevalence of supplement use was high in this study population with 56% of participants reporting supplement use; the most popular supplements consumed were multivitamins (28% and vitamin C (28%. A higher DGI score was significantly associated with an increased likelihood of supplement use (mean: 105 ± 18 vs. 109 ± 17, p = 0.001. Micronutrient supplement use was associated with a higher DGI score, suggesting that supplements are more likely to be used by those who are less likely to require them.

International Nuclear Information System (INIS)
Stern, S.; Greenberg, I.D.; Corne, R.
1991-01-01
To determine the effect of different types of exercise supplementation on dipyridamole thallium image quality, 78 patients were prospectively randomized to one of three protocols: dipyridamole infusion alone, dipyridamole supplemented with isometric handgrip, and dipyridamole with low-level treadmill exercise. Heart-to-lung, heart-to-liver, and heart-to-adjacent infradiaphragmatic activity ratios were generated from anterior images acquired immediately following the test. Additionally, heart-to-total infradiaphragmatic activity was graded semiquantitatively. Results showed a significantly higher ratio of heart to subdiaphragmatic activity in the treadmill group as compared with dipyridamole alone (p less than 0.001) and dipyridamole supplemented with isometric handgrip exercise (p less than 0.001). No significant difference was observed between patients receiving the dipyridamole infusion, and dipyridamole supplemented with isometric handgrip exercise. The authors conclude that low-level treadmill exercise supplementation of dipyridamole infusion is an effective means of improving image quality. Supplementation with isometric handgrip does not improve image quality over dipyridamole alone

Full Text Available Rosaceae (strawberry, cherry, blackberry, red raspberry, and black raspberry dietary supplements and food products (total n = 74 were purchased and analyzed to determine their anthocyanin concentrations and profiles. Eight of the 33 dietary supplements had no detectable anthocyanins (five samples or were adulterated with anthocyanins from unlabeled sources (three samples. Five of 41 food products contained no detectable anthocyanins. In mg per serving, the dietary supplements tested contained 0.02–86.27 (average 10.00, and food products contained 0.48–39.66 (average 7.76. Anthocyanin levels between the dietary supplements and food products were not significantly different in mg per serving. Individual anthocyanin profiles can be used to evaluate quality of Rosaceae food products and dietary supplements. These findings show that increasing anthocyanin content and reducing adulteration could improve the quality of Rosaceae products available in the marketplace.

2015-01-01
Full Text Available The article discusses the new iodine-containing supplements (ID derived from organic media collagenous animal protein (pork rind, carpatina and collagen and protein concentrates brands SCANGEN and PROMIL C95. It is shown that the use of these proteins as carriers of iodine is due to the high content of the amino acids glycine and alanine, which correlates with the degree of binding of iodine objects. New additives in addition to the special focus improve rheological properties of foods, including texture, appearance and functional properties. To assess the quality'ID and selection of preferred option the proposed qualitative assessment and a systematic approach to consider all'ID as a system to allocate its elements, to justify the principles of its construction and the requirements imposed on it, to build a General decision tree. For the construction of complex criterion for assessing the quality'ID proposed procedure formalization based on selection and evaluation of individual indicators, the definition of the laws of their change, depending on the dose, duration and temperature of exposure, and functional efficiency. For comparative evaluation of single and calculation of group indicators all of them were reduced to a single dimension by introducing the dimensionless coefficients of adequately describing the analyzed indicators. The article presents the calculated values of single and group of indicators characterizing technological properties 'ID: the degree of binding of iodine, the binding rate of iodine, heat losses of iodine and basic functional and technological properties of meat stuffing systems (water-binding, moisture-holding, emulsifying capacity and emulsion stability, obtained by the introduction of stuffing in the system studied'ID. At the final stage is the selection of the best 'ID, on the basis of an assessment of group performance.

Ratriyanto, A.; Indreswari, R.; Dewanti, R.; Wahyuningsih, S.
2018-03-01
This experiment investigated the effect of betaine supplementation to low methionine diet on egg quality of quails. A total of 340 laying quails (Coturnix coturnix japonica) was divided into 4 dietary treatments with 5 replicates of 17 quails each. The experiment was assigned in a completely randomized design. The four dietary treatments were the low methionine diet (0.3% methionine) without betaine supplementation and the low methionine diet supplemented with 0.07, 0.14, and 0.21% betaine. The experimental diets were applied for 8 weeks and the egg quality traits were measured at the age of 16 and 20 weeks. The data were subjected to analysis of variance, and when the treatment indicated significant effect, it was continued to orthogonal polynomial test to determine the optimum level of betaine. Increasing dietary levels of betaine increased the fat content of the egg with the linear regression of y = 11.0949 + 4.1914x (R2 = 0.18). However, supplementation of betaine did not affect protein content, yolk, albumen, and eggshell percentage. It can be concluded that betaine supplementation up to 0.21% to low methionine diet only had little effect in improving the quality traits of quail eggs.

MALDI-TOF MS for quality control of high protein content sport supplements.
De Ceglie, Cristina; Calvano, Cosima D; Zambonin, Carlo G
2015-06-01
High protein content sport nutritional supplements are found as powder products containing, as ingredients, amino acids and proteins with important nutritional values as milk, soy and egg proteins. An EU Food Supplements Directive (2002) requires that supplements should be safe, both in dosages and in purity. It is important, then, to develop rapid and sensitive methods to be employed for the quality control of these substances. In this work, we apply, for the first time, matrix-assisted laser desorption ionization-mass spectrometry as a fast, reproducible and sensitive method for the quality control of sport nutritional supplements based on proteins. To this aim, several commercial egg- and/or milk-based powder products have been processed by in gel or in solution digestion and analyzed in comparison to pure standard products. This strategy allowed to assess the reliability of the indications on proteins (as caseins, whey proteins and ovalbumin) declared in the label of several sport nutritional supplements.

[Cooking quality of pastas supplemented with rice bran].
Sangronis, E; Cafiero, J; Mosqueda, M
1997-06-01
The purpose of this study was to evaluate the quality during and after cooking of four pastas spaghetti type. Rice bran was used as ingredient in order to increase protein and dietetic fiber content. In two of the four formulation, semolina durum was supplemented with 10 and 20% rice bran. In the other two formulation granular flour was supplemented with 10 and 20% rice bran. Time cooking, water absorbtion, solid loss, color and hardness, (instrumental and sensory), Protein Efficiency Ratio (PER) and Apparent Digestibility in vivo were determined. Acceptability was evaluated by a 35-member consumer panel. Rice bran improved solid loss during cooking and increased cooking time, PERs were not affected significantly but Apparent Digestibility decreased when rice bran was increased. Sensory quality was affected because rice bran made pastas hard and dark but they were comparable to high fiber pasta existing in market.

Full Text Available Background Impaired sleep quality is commonplace within industrialized societies, as evidenced by the increasing number of prescription sleep aids available. Certain herbal preparations have been suggested to provide a natural benefit to sleep; however, limited controlled data are available documenting this benefit. In the present study we tested the effect of an experimental dietary supplement, containing the active ingredients Chlorophytum borivilianum and Velvet bean, on sleep quality using the Pittsburgh Sleep Quality Index (PSQI. Methods Eighteen healthy and active men and women, with evidence of impaired sleep quality, consumed the supplement daily for 28 days. The PSQI was administered before and after the intervention period. As indicators of safety, resting heart rate and blood pressure were measured, and a complete blood count, comprehensive metabolic panel, and lipid panel were determined. Results Sleep quality was influenced by the supplement, as evidenced by an improvement in every category of the PSQI questionnaire ( P < 0.05, with most category scores improving approximately 50% from pre to post intervention. No adverse outcomes were noted with use of the supplement, as indicated by no change in resting heart rate, blood pressure, or any bloodborne parameter. Conclusions An investigational dietary supplement containing the active ingredients Chlorophytum borivilianum and Velvet bean improves sleep quality in men and women. Additional placebo controlled trials are needed to corroborate these findings in individuals with self-reported sleeping difficulty.

Blastocyst production in vitro seems to be crucial part of assisted reproduction techniques in feline species. However, the results of cats' oocyte maturation and embryo development are still lower than those in other species. The aim of this study was to evaluate whether the supplementation with superoxide dismutase (SOD) and taurine during maturation or culture would improve the blastocyst yield obtained from lower grades of oocytes, that are usually discarded, as not suitable for further in vitro purposes. To investigate the effect of antioxidants' addition, the good- and poor-quality oocytes, were cultured with the addition of 10-mmol taurine and 600 UI/mL SOD. The nuclear maturity, embryo development, and blastocyst quality were subsequently assessed. In control group, without antioxidant supplementation, significantly less poor-quality oocytes matured (42% vs. 62%) and more degenerated (35% vs. 20%), comparing to the experimental group supplemented with SOD and taurine. The amount of obtained blastocyst was much higher, when poor quality oocytes were supplemented with SOD and taurine (supplementation to IVM-4%; supplementation to IVC-5.5%; supplementation to IVM and IVC-5.9% of blastocyst), comparing to not supplemented control group (1.3%). The best blastocysts were obtained when poor oocytes had antioxidants added only during embryo culture (185 ± 13.4 blastomeres vs. 100 ± 1.5 in control). In the present study, we reported that the lower grades of oocytes can better mature and form significantly more blastocysts with better quality, when cultured with addition of SOD and taurine.

Full Text Available The study investigated the effect of supplementation of the leaf powders of Telfairia occidentalis, Amaranthus viridis, and Solanum macrocarpon on the chemical composition and the quality characteristics of wheat bread. The bread samples were supplemented with each of the vegetable leaf powders at 1%, 2%, and 3% during preparation. The bread samples were assayed for proximate composition, mineral composition, physical, sensory, and antioxidant properties using standard methods. The addition of vegetable powders significantly increased the protein (9.50 to 13.93%, fibre (1.81 to 4.00%, ash (1.05 to 2.38%, and fat (1.27 to 2.00%. Supplementation with vegetable powder however significantly decreased (p<0.05 the carbohydrate and moisture contents. Significant (p<0.05 increases were recorded for all evaluated minerals as the level of vegetable powder increased. Supplementation with vegetable powder caused significant decrease in total phenolic content, percentage DPPH inhibition, metal chelating ability, ferric reducing antioxidant power, and total antioxidant capacity. Sensory results showed that there was significant decrease in sensory qualities with increasing supplementation. This therefore suggests that bread supplemented with vegetable powder could have more market penetration if awareness is highly created.

This article describes a quality improvement process for "do not return" (DNR) notices for healthcare supplemental staffing agencies and healthcare facilities that use them. It is imperative that supplemental staffing agencies partner with healthcare facilities in assuring the quality of supplemental staff. Although supplemental staffing agencies attempt to ensure quality staffing, supplemental staff are sometimes subjectively evaluated by healthcare facilities as "DNR." The objective of this article is to describe a quality improvement process to prevent and manage "DNR" within healthcare organizations. We developed a curriculum and accompanying evaluation tool by adapting Rampersad's problem-solving discipline approach: (a) definition of area(s) for improvement; (b) identification of all possible causes; (c) development of an action plan; (d) implementation of the action plan; (e) evaluation for program improvement; and (f) standardization of the process. Face and content validity of the evaluation tool was ascertained by input from a panel of experienced supplemental staff and nursing faculty. This curriculum and its evaluation tool will have practical implications for supplemental staffing agencies and healthcare facilities in reducing "DNR" rates and in meeting certification/accreditation requirements. Further work is needed to translate this process into future research. © 2012 Wiley Periodicals, Inc.

In 2002, the U.S. Department of Energy (DOE) documented a plan for accelerating cleanup of the Hanford Site, located in southeastern Washington State, by at least 35 years (DOE 2002). A key element of the accelerated cleanup plan was a strategic initiative for acceleration of the tank waste program and completion of ''tank waste treatment by 2028 by increasing the capacity of the planned Waste Treatment Plant (ETP) and using supplemental technologies for waste treatment and immobilization''. The plan identified specific technologies to be evaluated for supplemental treatment of as much as 70% of the low-activity waste (LAW). The objective was to complete required testing and evaluation that would ''...bring an appropriate combination of the above technologies to deployment to supplement LAW treatment and immobilization in the WTP to achieve the completion of tank waste treatment by 2028''. In concert with this acceleration plan, DOE, the U.S. Environmental Protection Agency, and the Washington State Department of Ecology have proposed to accelerate from 2012 to 2005 the Hanford Federal Facility Compliance Agreement (Tri-Party Agreement) milestone (M-62-08) associated with a final decision on treatment of the balance of tank waste that is beyond the capacity of the currently designed WTP

To examine the best evidence available regarding the effect of melatonin supplementation during controlled ovarian stimulation (COS) on the main assisted reproductive technology (ART) outcomes. Systematic review and meta-analysis of randomized clinical trials (RCT). Not applicable. Women undergoing COS for ART. Melatonin supplementation during COS for women undergoing ART. Live birth rate, clinical pregnancy rate, number of retrieved oocytes, miscarriage rate, ovarian hyperstimulation syndrome (OHSS) rate, and number of congenital abnormalities. Comparisons were performed using risk ratio (RR) or mean difference (MD). Five RCTs were considered eligible, and their data were extracted and included in a meta-analysis. No studies reported live-birth or congenital abnormalities. Our estimates were imprecise for distinguishing between no effect and benefit considering clinical pregnancy (RR, 1.21; 95% confidence interval [CI], 0.98-1.50, five studies, 680 women, low quality-evidence) and the number of oocytes retrieved (MD, 0.6; 95% CI, -0.2-2.2, five studies, 680 women, low quality-evidence). Our estimates were imprecise for distinguishing among harm, no effect, and benefit considering miscarriage (RR, 1.07; 95% CI, 0.43-2.68, two studies, 143 clinical pregnancies, low quality-evidence) and interventions to reduce the risk of OHSS (RR,1.01; 95% CI, 0.33-3.08, one study, 358 women, low quality-evidence). More studies investigating the role of melatonin supplementation are still needed before recommending its use in clinical practice. Copyright © 2014 American Society for Reproductive Medicine.

At the request of the U.S. Department of Energy Office of River Protection, Pacific Northwest National Laboratory (PNNL) conducted a scoping study to investigate supplemental technologies for supplying vertical fluid motion and enhanced mixing in Waste Treatment and Immobilization Plant (WTP) vessels designed for high solids processing. The study assumed that the pulse jet mixers adequately mix and shear the bottom portion of a vessel. Given that, the primary function of a supplemental technology should be to provide mixing and shearing in the upper region of a vessel. The objective of the study was to recommend a mixing technology and configuration that could be implemented in the 8-ft test vessel located at Mid-Columbia Engineering (MCE). Several mixing technologies, primarily airlift circulator (ALC) systems, were evaluated in the study. This technical report contains a review of ALC technologies, a description of the PNNL testing and accompanying results, and recommended features of an ALC system for further study.

To determine the effects of lipid-based nutrient supplements (LNS) on the quality of life of people living with HIV (PLHIV) during the first 3 months of antiretroviral treatment (ART) and to investigate the effects of timing of supplementation by comparing with supplementation during the subsequent 3 months. A randomised controlled trial was conducted in three ART clinics within public health facilities in Jimma, Ethiopia. Participants were PLHIV eligible to start ART with body mass index >17 kg/m(2) and given daily supplements of 200 g of LNS containing whey or soya either during the first 3 months or the subsequent months of ART. The outcome was measured in terms of total quality-of-life scores on the adapted version of the WHOQOL-HIV-BREF assessed at baseline, three and six months. Of the 282 participants, 186 (66.0%) were women. The mean age (SD) was 32.8 (±9.0) years, and the mean (SD) total quality-of-life score was 82.0 (±14.8) at baseline assessment. At 3 months, participants who received LNS showed better quality of life than those who only received ART without LNS (β = 6.2, 95% CI: 2.9: 9.6). At 6 months, there was no difference in total quality-of-life score between the early and delayed supplementation groups (β = 3.0, 95% CI: -0.4: 6.4). However, the early supplementation group showed higher scores on the social and spirituality domains than the delayed group. LNS given during the first three months of ART improves the quality of life of PLHIV. © 2016 John Wiley & Sons Ltd.

Full Text Available Abstract Background The objectives of this study were to investigate the effects of persimmon peel (PPM supplementation on carcass performance, pork quality, eating quality, fatty acid composition, and cholesterol concentration of the porcine longissimus dorsi muscle. Results No adverse effects of PPM supplementation were observed on carcass and meat quality characteristics among the treatment groups (P > 0.05, whereas pork loins from pigs fed a diet supplemented with 0.9 % persimmon peel (T3 showed more tender meat than did pork loins from pigs fed a control diet (P < 0.01, even though no significant difference was observed between the control and T1 group. The T3 group had higher ratio of polyunsaturated fatty acids relative to saturated fatty acids (0.33 vs. 0.28, P < 0.05 and lower total cholesterol concentration (94.4 vs. 99.1 mg/g, P < 0.05 compared to the control group. Persimmon peel appeared to have beneficial effects on fatty acid composition and cholesterol concentration, probably leading to a hypocholesterolemic effect. Conclusions Animal diets fortified with persimmon peel represents an efficient and useful method for improving the nutritional quality of pork without impairing growth performance and eating quality properties.

In the tropical arid and semi-arid regions of many developing countries, sheep are predominantly grazed on low-quality pastures and stall-fed on crop residues. This study evaluated the potential of Grewia oppositifolia tree leaves as crude protein (CP) supplement to the low-quality diets of sheep in comparison with cottonseed cake (CSC). Changes in the chemical composition of the leaves with progressive maturation (December to March) were studied. The leaves maintained a high CP content (>164 g/kg dry matter (DM)) during the prolonged maturation in the winter feed scarcity period. The leaves were rich in Ca (41 g/kg DM) and K (89 g/kg DM). The rate of degradation and effective degradability of CP were consistently higher (P < 0.001) in CSC than in G. oppositifolia. A balance trial in a 4 × 4 Latin square design with four mature Ramghani wethers showed that DM intake, DM and CP digestibility, and N retention did not differ with the substitution of CSC with G. oppositifolia leaves, as a supplement to a basal diet of sorghum hay. Body weight (BW) gain and wool yield responses to the supplements were examined with 36 lambs (27 ± 3 kg BW; age 11 ± 1 months) for 15 weeks. The lambs were only grazed on local pasture (control group) or supplemented with CSC, G. oppositifolia leaves, and their mixture on iso-N basis. Addition of the supplements increased (P < 0.05) BW gain and wool yield, and the leaves were as effective as CSC. These results demonstrated that G. oppositifolia leaves provide good quality green fodder during the prolonged winter feed scarcity period, and that the leaves can be efficiently utilized as a CP supplement to the low-quality diets of sheep.

1997-06-01
The objective of this research was to investigate the potential of using rice bran as an ingredient in pastas spaghetti type. Two of the pastas were made with semolina from durum as raw material, supplemented with 10 and 20% rice bran. The other two were made with granular flour and the same percentage of rice bran. Proximate composition of raw material was analyzed. Pastas were elaborated in a local industry. Composition, proximal, color, texture, and sensorial quality of pastas were determined. Protein content (13.9-15.0%), ash (1.47-3.09%) and dietary fiber (6.71-8.45%) of pastas increased according to the percentage of rice bran added. The hardest pastas were those elaborated with semolina from durum wheat and with a 10% of substitution. Also, they were the most yellow. The sensory panel found differences in quality among the pastas evaluated. Pastas with 10% rice bran had the best quality. The results demonstrated that is possible to elaborate pastas with 20% as maximum of rice bran resulting products with high protein, ash and dietetic fiber content, but some undesirable characteristics were given by the rice bran as white spots, wrinkles and color changes.

Twenty-one lactating Italian Friesian cows (at 220±20 days of lactation were equally allocated to 3 treatments: group C received no supplementation, group D was offered 136 g of docosahexaenoic acid (DHA per day and group E was supplemented with 136 g of DHA + 2000 U.I. of vitamin E per day. Individual milk production was recorded weekly and samples were collected for analysis of milk composition and fatty acid profile. At the end of the trial and 2 weeks later animals were subcutaneously injected with 5 mg of keyhole limpet haemocyanin (KLH, whereas at the end of the trial and 8 weeks later skinfold thickness was measured after intradermal injection with 500 mg phytohaemagglutinin. Dietary treatment showed no effect on milk production. Concentrations of DHA were higher (P<0.05 in milk fat from D and E groups, whereas polyunsaturated fatty acids tended to be higher (P<0.10. When DHA and DHA + vitamin E were supplemented to the animals, milk sensory properties were significantly modified as samples from groups D and E could be discriminated from the control using the triangle test (P<0.001. Both supplemented groups showed evidence of increased antibody response 4 to 8 weeks after the first KLH administration (P<0.05. In the two skin tests the treated groups showed a higher skin thickening in comparison with control animals (P<0.05. Although provided in a late stage of lactation, an n-3 fatty acid enriched diet favourably changed milk fatty acid profile and promoted animal healthiness by enhancing cellular and humoral immune response.

To evaluate the effects of copper (Cu) supplementation on the serum lipid profile, meat quality, and carcass composition of goat kids, thirty-five 3-4-month-old Jian Yang big-eared goat kids (BW 20.3±0.6 kg) were randomly assigned to one of seven dietary Cu treatments (n=5/treatment). The dietary Cu concentrations were: (1) control (no supplemental Cu), (2) 20 mg, (3) 40 mg, (4) 80 mg, (5) 160 mg, (6) 320 mg, and (7) 640 mg of supplemental Cu/kg dry matter (DM). Copper was supplemented as CuSO4.5H2O (25.2 % Cu). The goats were fed a high-concentrate basal diet with the different concentrations of supplemental Cu/kg DM for 96 days. The serum lipid profile was determined on day 51 and day 96. Meat quality and carcass composition of longissimus dorsi muscle were measured after the goats were slaughtered at 96 days. Serum total cholesterol, triglycerides, high density lipoprotein-cholesterol (HDL-C), and low density lipoprotein-cholesterol (LDL-C) were not affected by treatment (P>0.18). No differences were observed in drip loss, cooking loss, a* (redness/greenness) and b* (yellowness/blueness) values (P>0.17); however, the 24-h pH value (linear; P=0.0009) and L* (brightness) value (linear; P=0.0128) decreased, and shear force increased (linear; P=0.0005) as Cu supplementation increased. The intramuscular fat (%) increased (linear; P=0.001) as supplemental Cu increased. No differences (P>0.21) in the moisture, crude protein, and ash (%) were observed. Results of this study indicate that supplemental Cu does not modify the serum lipid profile; however, it can impact intramuscular fat content and the meat quality of goat kids.

Full Text Available The objective was to evaluate the dietary supplementation of different sources of chromium (inorganic: chromium sulfate and chelated: chromium-methionine during the finishing period of pigs to obtain improvements in the animal performance, and carcass and meat quality. The statistical design was randomized blocks, where 44 barrows, with an initial weight 60.49±5.12 kg, were divided into four blocks (heavier, heavy, light and lighter according to initial weight. The experimental diets were isoenergetic and isonutrient, except for the chromium level. The treatments were divided as follows: control (without chromium, control + 200 ppb of inorganic chromium (chromium sulfate, and control + 200 ppb of chelated chromium (chromium-methionine. In the performance measures, the stall was considered the experimental unit and in the blood parameters, carcass and meat evaluations each animal constituted the experimental unit. Animals were slaughtered when they reached the final average weight of 107.23±5.23 kg. Blood samples were collected and tested for blood parameters (cholesterol, triglycerides and glucose as well as carcass quality (hot and cold weights, yield, loin-eye area, muscle depth and backfat thickness and meat quality (initial and final pH, drip loss, color, chemical composition and lipid oxidation parameters. Chromium-methionine supplementation provides a greater daily weight gain only compared with the animals that are not supplemented with chromium, because feed conversion is better as compared with the other treatments. After 24 hours of storage, the meat from pigs supplemented either with chromium-methionine or with chromium sulfate presents lower lipid oxidation than that from non-supplemented animals. However, after three days of storage, only chromim-methionine is effective in reducing lipid oxidation.

This experiment was conducted to investigate the effect of basal dietary supplementation with 500 mg/kg alpha-lipoic acid (LA) on growth performance, antioxidant capacity and meat quality in different stages in broiler chickens. A total of 240 Arbor Acre chickens were randomly assigned into 4 treatment groups, each treatment containing 6 replicates of 10 chickens each. Group 1 was the control group without LA supplementation; Group 2 was supplied with LA in the starter period; Group 3 was supplied with LA in the grower period; and Group 4 was supplied with LA in the whole period. The results showed that LA supplementation improved average feed intake and body weight gain in all three experimental groups, especially in Group 2. LA supplementation significantly decreased abdominal fat yield in Groups 3 and 4. LA supplementation all improved hepatic total antioxidant capacity, the level of glutathione, the activities of total superoxide dismutase, catalase (CAT) and glutathione peroxidase, in particular in Group 4. LA supplementation decreased the activity of liver xanthine oxidase (XO) in all experimental groups, and that of liver monoamine oxidase in Group 3. The activities of liver CAT and XO in Group 2 were higher than that in Group 3. LA supplementation elevated the pH24 h and decreased drip loss in breast meat in Groups 3 and 4. In conclusion, LA supplementation can improve growth performance, antioxidant properties and meat quality in broiler chicken. LA supplementation in the starter period can improve growth performance and supplementation in the grower - and in the whole period can improve carcass characteristics. There was no significant difference in meat quality of broiler chickens fed on LA-supplemented diet in different stages.

Full Text Available This study focuses on the effect of a mineral supplementation on meat quality of pigs for slaughter; for these two groups of finishing pigs they were used; a control group that did not receive mineral supplement and other that consumed a mineral supplement three days before slaughter. In the slaughterhouse, were collected samples of Longissimus dorsi, which were vacuum packed, frozen and sent to the laboratory for evaluation later; in these samples shear force, color and pH was determined. After statistical analysis found that the performance variables, shear force and pH were not different (p>0.1; Only the color was significantly different (p<0.1, so it is concluded that it is possible to improve the presentation of pork by administering mineral salts anti-stress animals three days before slaughter, without the carcass yield and pH are affected.

This study was carried out with the purpose of evaluating the effect of supplementing hens' diets with trace minerals from inorganic or organic sources on the productive performance, eggshell quality, and eggshell ultrastructure of laying hens. Three hundred sixty Hy-Line W36 laying hens between 47 to 62 wk of age were used and distributed in a completely randomized experimental design with 9 treatments, 5 replicates, and 8 birds for each experimental unit. The treatments consisted of a control diet without supplementation of the trace minerals Mn, Zn, and Cu; 4 supplementation levels of these trace minerals from an inorganic source; and the same levels of supplementation from an organic source (proteinates). The supplementation levels in milligrams per kilogram for Mn, Zn, and Cu, were, respectively, 35-30-05, 65-60-10, 95-90-15, and 125-120-20. There was no effect of supplementation of trace minerals on the rate of posture, feed intake, feed conversion, specific weight, and Haugh unit of eggs. However, there was a quadratic effect (P < 0.05) of the levels of trace mineral supplementation on average egg weight and egg mass; the results did not differ regarding the source used. The increase in the levels of supplementation of Mn, Zn, and Cu provided a linear increase (P < 0.05) in the breaking strength and the percentage of eggshell. There was a linear decrease (P < 0.05) in the egg loss and the number of mammillary buttons in the shell. The best results were obtained using diets supplemented with trace minerals from an organic source because these diets provided lower egg loss, higher thickness, and increased strength of the shell. Structurally, organic Mn, Zn, and Cu provided higher thickness of the palisade layer and lower mammillary density. The trace mineral supplementation improved the structural characteristics and the quality of the eggshells.

Reis, Rogerio Alves de Sousa; Saiki, Mitiko
2005-01-01
The increasing consumption of nutritional supplements among the people mainly aiming at the replacement of nutrients and minerals in the organism has led the commercialization of a great number of brands of these products. Consequently the quality control of these products is of great interest to verify if their element contents agree the values presented in labels or in the instructions for their uses. In this study the elements Ca, Co, Cr, Cu, Fe, K, Na, Se and Zn were analyzed in multimineral supplements and vitamins samples using neutron activation analysis method. The results obtained compared with the values of the labels of nutritional supplements presented good agreement. For quality control of the analytical data, certified reference materials NIST 1400 Bone Ash and NIST 1633b Coal Fly Ash provided by National Institute of Standards and Technology were analysed. Accuracy and precision of the results were evaluated and Z score values obtained were lower than 2 indicating that the data found are within the certified values at 95% of significance level.

The aim of this study was to investigate the influence of different methionine sources and concentrations on the quality and spoilage process of broiler meat. The trial was comprised of 7 treatment groups: one basal group (suboptimal in Methionine+Cysteine; i.e., 0.89, 0.74, 0.69% in DM SID Met+Cys in starter, grower, and finisher diets, respectively) and 3 doses (0.10, 0.25, and 0.40%) of either DL-Methionine (DLM) or DL-2-hydroxy-4-methylthio butanoic acid (DL-HMTBA) on an equimolar basis of the DLM-supplemented groups. The broilers were fed the diets for 35 d, then slaughtered and processed. The filets were aerobically packed and stored under temperature controlled conditions at 4°C. Meat quality investigations were comprised of microbial investigations (total viable count and Pseudomonas spp.), pH and drip loss measurements of the filets. The shelf life of the meat samples was determined based on sensory parameters. After slaughtering, all supplemented meat samples showed a high quality, whereby no differences between the 2 methionine sources could be detected for the microbial load, pH, and drip loss. In comparison to the control group, the supplemented samples showed a higher sensory quality, characterized by a fresh smell and fresh red color. Methionine supplementation had a significant influence on meat quality parameters during storage. The microbial load, pH and drip loss of the chicken filets were positively correlated to the methionine concentration. Additionally, the microbial load at the end of storage was positively correlated to pH and drip loss values. Nevertheless, the microbial parameters were in a normal range and the positive correlation to methionine concentration did not affect the sensory shelf life. The mean sensory shelf life of the broiler filets varied between 7 to 9 d. During storage, no difference in the development of sensory parameters was observed between the supplemented groups, while the spoilage process of the basal group

To evaluate the effect of a dietary supplement containing polyunsaturated fatty acids, in association with Humulus lupulus extract, on the quality of sleep using the Leeds sleep evaluation questionnaire (LSEQ) in subjects with moderate to severe sleep disorders. Randomized placebo-controlled trial, in a Population-based setting. Participants were adult patients 25 to 65 years old with a chronic primary insomnia who volunteered for the study. The tested intervention consisted of two soft gelatine capsules per day, containing either the dietary supplement (active group) or olive oil (placebo group) for a month. Subjects could also volunteer for two ancillary studies on melatonin and actigraphy. Evaluation criteria included i) perception of the quality of sleep at the end of treatment using the LSEQ questionnaire, ii) sleep efficiency measured by one-week actigraphic movement measurement performed before and during the treatment in a subsample of subjects, iii) night melatonin and 6 sulfatoxymelatonin (aMT6S) urine rates in a subsample of subjects. The average of Leeds score was similar in both groups (p = 0.95). A marked improvement in the quality of sleep was observed in both placebo (62%) and active (65%) group (p = 0.52). The evolution of urinary melatonin, aMT6S, and of the Mel/aMT6S ratio showed no differences between the two groups. Sleep efficiency, as measured by actigraphy, improved similarly in both groups during the treatment period, from 72% to 76% and 75% in the active and placebo group respectively (p = 0.91). The dietary supplement had neither effect on the perceived quality of sleep, nor on the melatonin metabolism and sleep-wake cycle. clinical trials.gov:NCT00484497.

Maca (Lepidium meyenii Walpers), is an Andean crop that grows between 3,800 and 4,500 m a.s.l. The persistent interest in this plant is based on its assumed effects on fertility of male mammals due to the prevalence of certain, partially specific, secondary compounds. The present study aimed at evaluating the effect of maca supplementation on quality and quantity of semen, mating behavior, and clinical status of peripubertal breeding bulls. The experiment followed a cross-over design lasting for 23 wk with 3 wk of adaptation and baseline measurements, and 2 x 10 wk of treatment feeding thus covering two times the complete 8-wk spermatogenic cycle. Seventy-eight 55 wk to 84 wk old breeding bulls received either no maca (control) or maca (233 mg dried hypocotyls/kg body weight/day) for 10 wk followed by 10 wk without maca (maca early) or maca only in the last 10 wk (maca late). Measurements were always made in the last 2 wk of each period. Apart from standard analyses, ejaculates were analyzed by flow cytometry. Data was evaluated by analysis of variance considering the repeated measurement structure of the data. Significant treatment by measurement period indicated direct or carry-over effects of maca. Maca supplementation had no direct effect on body weight, testes circumference, rectal temperature, mating behavior, and ejaculate volume. However, supplementing maca in the first 10 wk period increased the number of sperms in the second 10 wk period, i.e., when the animals no longer received maca. The DNA fragmentation index and the visually assessed motility of the sperms of bulls, that initially showed a borderline sperm quality, were significantly improved with early maca supplementation, while no such effect was observed in the two other groups. No effects occurred in the proportion of intact sperm plasma membranes or acrosomes or both. In conclusion, maca supplementation seems to improve sperm quantity and quality of bulls to a certain degree, while mating

This study aimed to investigate the influence of an oral antioxidative supplementation on sperm quality of in vitro fertilization (IVF) patients, as analyzed by sperm motility according to the WHO criteria and motile sperm organelle morphology examination (MSOME). Semen samples were collected from 147 patients before undergoing an IVF/intracytoplasmic morphologically-selected sperm injection (IMSI) cycle and 2 - 12 months after an antioxidative supplementation. Semen analysis was evaluated according to WHO and MSOME criteria. Spermatozoa were grouped according to the size of nuclear vacuoles within the sperm's heads. Patients were divided into oligoasthenoteratozoospermic (OAT) and non-OAT men. Between first and second semen analysis, patients were supplemented orally with an antioxidative preparation. After the antioxidative therapy we observed a significant reduction in the percentage of immotile sperm cells in the patients. Additionally, the percentage of class I spermatozoa according to MSOME criteria was significantly higher after antioxidative supplementation. In OAT patients the percentage of class I sperm was found to be increased, although not significantly. However, we observed a drastic improvement in sperm motility as well as in total sperm count in this group. The results demonstrated a considerable improvement in semen quality, notably in OAT patients. Considering the putative relationship between semen quality on the one hand and reactive oxygen species on the other, the observed changes in the sperm parameters indicate that a decline in semen quality, and even subtle morphological changes, might be associated with oxidative stress. Our findings suggest that an antioxidative and micronutrient supplementation has a remarkable benefit for IVF patients having restricted sperm parameters, in particular.

Effect of Supplementation with Antioxidants on the Quality of Bovine Milk and Meat Production
Castillo, Cristina; Pereira, Víctor; Abuelo, Ángel; Hernández, Joaquín
2013-01-01
From a clinical point of view, oxidative stress (OS) is considered the primary cause of numerous metabolic processes in transition cow. Thus, the addition of antioxidants has been considered a palliative or preventive treatment. But beyond the clinical perspective, antioxidant supplementation provides an added value to the product obtained being either milk or meat. This paper reviews the beneficial aspects that provide antioxidant supplementation on quality of both products and that fit into the new concept that the consumer has a functional and healthy food. Our approach is from a veterinary standpoint, by reviewing the studies conducted to date and the new perspectives that are interesting and need to be studied in the following years. One of the highlights is that sustainable farming, one in which production is combined with animal health, also impacts positively on the quality of the final products, with beneficial antioxidant properties to human health.

Natural products have provided a basis for health care and medicine to humankind since the beginning of civilization. According to the World Health Organization (WHO), approximately 80% of the world population still relies on herbal medicines for health-related benefits. In the United States, over 42% of the population claimed to have used botanical dietary supplements to either augment their current diet or to "treat" or "prevent" a particular health-related issue. This has led to the development of a burgeoning industry in the U.S. ($4.8 billion per year in 2008) to supply dietary supplements to the consumer. However, many commercial botanical products are poorly defined scientifically, and the consumer must take it on faith that the supplement they are ingesting is an accurate representation of what is listed on the label, and that it contains the purportedly "active" constituents they seek. Many dietary supplement manufacturers, academic research groups, and governmental organizations are progressively attempting to construct a better scientific understanding of natural products, herbals, and botanical dietary supplements that have co-evolved with Western-style pharmaceutical medicines. However, a deficiency of knowledge is still evident, and this issue needs to be addressed in order to achieve a significant level of safety, efficacy, and quality for commercial natural products. The authors contend that a "quality by design" approach for botanical dietary supplements should be implemented in order to ensure the safety and integrity of these products. Initiating this approach with the authentication of the starting plant material is an essential first step, and in this review several techniques that can aid in this endeavor are outlined.

Experiments (Exp) I and II were conducted to compare raw whole soya beans (WSB), roasted (rWSB) or other protein sources as supplements of low-quality forages fed ad libitum to beef cattle, upon DM intake (DMI), ruminal and blood parameters, and animal performance. Exp I: treatments for wheat straw fed to four ruminally cannulated steers were (i) Control-WS: no supplement; (ii) WSB-WS: whole soya beans; (iii) rWSB-WS: roasted WSB; and (iv) SBM-WS: soybean meal-wheat midds mixture; all fed at 1.4 kg DM/day. Exp II: 12 steers grazed deferred grain sorghum (DS) receiving these treatments: (i) Control-DS: no supplement; (ii) WSB-DS: 1.26 kg DM/day whole soya beans; and (iii) SFM-DS: 1.35 kg DM/day of sunflower meal. In Exp I, WS DMI resulted 47, 52 and 41% greater for WSB-WS, rWSB-WS and SBM-WS, respectively, than Control-WS (p < .05). In Exp II, the DMI of DS was unaffected by supplementation; a substitution of DS by supplement was found for WSB-DS (p < .05); however, total diet and digestible DMI increased with supplementation (p < .05). Rumen pH in Exp I remained unaffected by supplementation, but N-NH 3 as well as blood urea-N in Exp II increased (p < .05). In Exp II, average daily weight gains improved similarly with both supplements compared with Control-DS. Additionally, feed-to-gain ratio decreased (p < .05), being lower for WSB-DS (8.3) vs. SFM-DS (9.9). Roasting effects of WSB as a supplement for low-quality forages were not detected, and all protein sources increased total diet DMI and forage utilization. Only moderate cattle weight gains could be expected for unsupplemented DS. © 2017 Blackwell Verlag GmbH.

The aim of the present study was to evaluate the effects of supplementation of semen extender with various non-enzymatic antioxidants on the quality of cooled or cryopreserved Arabian stallion spermatozoa. Semen collected from four pure Arabian stallions was centrifuged at 600g for 15 min. Spermatozoa were then diluted in INRA-82 extender supplemented with bovine serum albumin (BSA; 0, 10, 15 and 20 mg/mL) or trehalose (0, 75, 100 and 150 mM) or zinc sulphate (0, 100, 150 and 200 μM). The diluted semen was then either cooled at 5 °C or cryopreserved in 0.5-ml plastic straws. After cooling or thawing, sperm motility, viability, sperm abnormalities, viability index, and plasma membrane integrity were evaluated. The results showed that supplementation of semen extender with 150 mM trehalose or with 200 μM zinc sulphate significantly (P < 0.05) improved motility, viability, sperm membrane integrity and acrosome status in Arabian stallion spermatozoa after cooling or after freezing and thawing compared with controls (non-supplemented media) or with those supplemented with other concentrations of trehalose or zinc sulphate. Supplementation of semen extender with BSA did not improve sperm motility or cryosurvival of Arabian stallion spermatozoa after cooling or after freezing and thawing. In conclusion, supplementation of semen extender with non-enzymatic antioxidants (trehalose or zinc sulphate) improved the quality of chilled and frozen/thawed Arabian stallion spermatozoa. The most beneficial effects occur when semen diluent was supplemented with 150 mM trehalose or 200 μM zinc sulphate. Copyright © 2017 Elsevier Inc. All rights reserved.

Full Text Available Diabetes UK has recently listed a number of herbs and spices that have been clinically shown to improve blood glucose control in type-2 diabetes patients and the diabetes high-risk group. With Aloe vera being top in this list, its health benefit along with health and beauty/food retailers supplying it was illustrated in detail. Previous article from this laboratory scrutinised the merit of using A. vera as an alternative therapy to prescription antidiabetic drugs and the risk of using food supplements in the market which do not qualify as drug preparations. In continuation of this discussion, the present study assesses three Aloe Pura brands and one Holland and Barret brand of A. vera juice supplements in the UK market through chromatographic and spectroscopic analysis. While the polysaccharide active ingredient, acemannan, appears to be within the recommended limit, it was found that Aloe Pura (one of the best-selling brands for A. vera supplement products have benzoate additive that does not appear in the supplement levels. Moreover, two of the Aloe Pura brand juices contain methanol, suggesting that the International Aloe Science Council (IASC certification does not guarantee the medicinal quality of these products. The therapeutic fitness of such supplements is discussed.

An experiment was conducted to investigate the effects of phytase and 2 levels of fructooligosaccharide (FOS) supplementation on growth performance, bone mineralization, and P utilization of broiler chickens. A total of 210 day-old male broiler chickens (Ross) were randomly placed into 7 dietary treatments consisting of 6 replicates with 5 birds per pen. The experiment was designed as an augmented 2 × 3 factorial arrangement with 0 or 500 U/kg of phytase and 0, 0.5% or 1% of FOS added to a reduced Ca (0.8%) and available P (0.25%) negative control diet (NC). A positive control diet (PC) that contained 1% Ca and 0.45% available P was also included. During the entire experimental period, phytase supplementation significantly improved (P Phytase supplementation increased femur BMD (P Phytase alone and in combination with 0.5% FOS increased P utilization significantly when compared with other treatments (P phytase supplementation in low Ca and P diets improved growth performance, bone quality, and P utilization. However, supplementing NC diets with phytase and FOS did not result in bone mineralization values comparable with that of the PC diet. The application of dietary FOS alone had a negative effect on broiler bone quality. © 2015 Poultry Science Association Inc.

Our approach is from a veterinary standpoint, by reviewing the studies conducted to date and the new perspectives that are interesting and need to be studied in the following years. One of the highlights is that sustainable farming, one in which production is combined with animal health, also impacts positively on the quality of the final products, with beneficial antioxidant properties to human health.

Granulocyte macrophage colony stimulating factor (GM-CSF) is a cytokine/growth factor produced by epithelial cells that exerts embryotrophic effects during the early stages of embryo development. We performed a systematic review, and six studies that were performed in humans undergoing assisted reproduction technologies (ART) were located. We wanted to evaluate if embryo culture media supplementation with GM-CSF could improve success rates. As the type of studies and the outcome parameters investigated were heterogeneous, we decided not to perform a meta-analysis. Most of them had a trend favoring the supplementation with GM-CSF, when outcomes were measured in terms of increased percentage of good-quality embryos reaching the blastocyst stage, improved hatching initiation and number of cells in the blastocyst, and reduction of cell death. However, no statistically significant differences were found in implantation and pregnancy rates in all apart from one large multicenter trial, which reported favorable outcomes, in terms of implantation and live birth rates. We propose properly conducted and adequately powered randomized controlled trials (RCTs) to further validate and extrapolate the current findings with the live birth rate to be the primary outcome measure.

Full Text Available The effects of dietary supplementation of onion, cranberry, strawberry and essentials oils on meat quality were analysed. Five groups of 48 Grimaud female weaned rabbits received the supplemented or the control ration; the experimental unit was a cage of 6 rabbits. Each experimental diet contained 10 ppm of added active ingredients. Rabbits were fed with the experimental diets for 4 wk before determining slaughter and carcass traits and determining the pH at 1 and 24 h post mortem (pHu of the Longissimus dorsi (LD and the Biceps femoris (BF muscle, left and right, respectively. Cooking loss, drip loss and L*, a* and b* color parameters were obtained of the right LD and for ground meat and antioxidant status (TBARS, DNPH, Folin Ciocalteu. Only the pHu of the LD muscle for the strawberry supplemented group was significantly lower when compared to the control group (P=0.04. However, we note that for the pH of the LD, the average was less than 6 for the meat of animals who received a diet enriched in polyphenols, compared to the control group. Plant extract supplementation did not influence meat quality traits, growth performance or oxidative stability. But under aerobic and anaerobic conditions, our results indicate that diet supplementation with extracts rich in polyphenols, especially with essential oils, had a small bot sporadic positive effect in reducing bacterial microflora compared to the control group (P<0.05. In conclusion, plant extracts and essential oils can be used in a rabbit diet without adverse effects on performance and meat quality traits. This effect could be optimized by investigating higher doses.

The advantage of supplemental sodium bicarbonate (NaHCO3) on eggshell quality in laying hens changes with age. Besides increasing calcium (Ca) secretion in the eggshell gland, it may improve Ca absorption in the intestine or kidney. Hy-Line Brown layers (n = 384), 25 weeks of age, were allocated to two treatment groups in two experiments, each of which included 4 replicates of 24 hens. Hens were fed a basal diet (control) or the basal diet containing 3 g NaHCO3 g/kg for 50 or 20 weeks in Experiment 1 or 2, respectively. A 24-h continuous lighting regimen was used to allow hens to consume the dietary supplements during the period of active eggshell formation. In Experiment 1, particularly from 25 to 50 weeks of age, and in Experiment 2, NaHCO3 supplementation favoured hen-d egg production at the expense of lower egg weight. The increased eggshell thickness should have nothing to do with the additional eggshell formation, because of the unchanged egg mass and daily eggshell calcification. At 35 weeks of age in both experiments, NaHCO3 supplementation increased duodenal expression of calbindin-d28k (CaBP-D28k) protein, contributing to higher Ca retention and balance. From 50 to 75 weeks of age in Experiment 1, the hens had little response to NaHCO3 supplementation and showed a negative trend on eggshell thickness and strength. It is concluded that dietary supplementation with 3 g NaHCO3 g/kg improves Ca absorption and eggshell quality of laying hens during the peak but not late production period, with the introduction of continuous lighting.

Effect of technology on quality assurance
International Nuclear Information System (INIS)
Purvis, E.E. III

Optimizing Quality Assurance activities by taking advantage of technological improvements is an issue directly related to overall product cost, quality, and delivery schedules. Use of automated tooling and numerical control have reduced manufacturing cycle time and thereby enabled better response to changing consumer tastes and market demand. Non-nuclear industries are using computer-aided technology for in-process inspection and final product acceptance. Non-destructive examination can also be performed real-time, on the production line. The challenge faced by the nuclear industry is to make the best use of new and emerging technology while satisfying compliance requirements. Currently, use of new methods is hampered by uncertainty about the affect on regulatory issues. Ways of using the technology have been developed for commercial applications without consideration of nuclear requirements

Full Text Available This study was carried out to evaluate the effect of artificial supplements prepared with soybean protein isolate, brewer's yeast, mixture of soybean protein isolate with brewer's yeast, linseed oil, palm oil, and a mixture of linseed oil with palm oil on the physicochemical and microbiological composition of royal jelly produced by Africanized honey bee colonies. Considering these results, providing supplements for Africanized honeybee colonies subjected to royal jelly production can help and strengthen the technological development of the Brazilian beekeeping industry increasing its consumption in the national market. This research presents values of royal jelly a little different from those established by the Brazilian legislation. This fact shows that is important to discuss or change the official method for royal jelly analysis. The characterization of physicochemical and microbiological parameters is important in order to standardize fresh, frozen, and lyophilized royal jelly produced by Africanized honeybees.

Full Text Available ABSTRACT The aim of this study was to assess the sperm quality and testicular histomorphometry of Wistar rats supplemented with extract and fractions of fruits of Tribulus terrestris L. The ethanolic extract was obtained by dynamic maceration of spray-dried fruit. This extract was fractionated by liquid-liquid partition, using increasing polarity solvents. Twenty male rats were separated in four groups, with five rats in each group. The control was supplemented with distilled water, while the others were daily given the ethanolic extract, hexanic or aqueous fraction soluble in methanol in a dose of 42 mg.kg-1.day-1 for 70 days. Sperm was obtained from the right epididymal tail for the analysis of motility, count, morphology and viability. The testicular weight of groups supplemented with ethanolic extract and aqueous fraction soluble in methanol was higher when compared to the control. The gonadosomatic index increased in the group supplemented with ethanolic extract. The nuclear, cytoplasmic and individual volume of Leydig cells increased in supplementation with hexanic and aqueous fractions soluble in methanol. It was concluded that the extract influenced the spermatogenesis, while hexanic and aqueous fractions soluble in methanol promoted the changes in the intertubular compartment. Therefore, Tribulus terrestris did not improve the sperm quality of the rats.

In order to improve boar sperm quality during frozen-thawed process, the influence of the presence of trehalose on success of cryopreservation of boar sperm were investigated. We evaluated freeze-thawing tolerance of boar spermatozoa in a base cooling extender with the addition of different trehalose concentrations (0, 25, 50, 100 and 200mmol/l), and tried to determine the optimum concentration of trehalose. We chose sperm motility, acrosome integrity, membrane integrity and cryocapacitation as parameters to evaluate cryopreservation capacity of boar spermatozoa. We obtained the best results for 100mmol/l trehalose-supplemented extenders, with values of 49.89% for motility, 66.52% for acrosome integrity and 44.61% for membrane integrity, while freeze-thawing tolerance was diminished significantly for 200mmol/l of trehalose. Before and after capacitation, the CTC score for semen diluted by extender containing 100mmol/l trehalose was 3.68% and 43.82%, respectively. In conclusion, trehalose could confer a greater cryoprotective capacity to boar spermatozoa. Trehalose-supplementation with 100mmol/l concentration in basic extender could significantly improve sperm motility, membrane integrity and acrosome integrity parameters, and reduce boar spermatozoa cryocapacitation during the cryopreservation process.

We investigated the quality characteristics and antioxidant activities of yogurt supplemented with 1%, 2%, and 3% aronia juice and fermented for 24 h at 37°C. The total acidity increased with increasing levels of aronia juice and incubation time. Lightness and yellowness of the yogurt decreased, but redness increased, with increasing aronia juice content and incubation time. The number of lactic acid bacteria (LAB) increased with increased incubation time, and yogurt containing 2% and 3% aronia juice showed higher LAB counts than 1% aroinia juice-supplemented yogurt. The total polyphenol and flavonoid contents increased proportionally with increasing levels of aronia juice. Antioxidant activity of aronia-containing yogurt was significantly higher than that of the control and increased proportionally with aronia juice concentration. Yogurt with 2% aronia juice had the best taste (Pyogurt. PMID:28078255

1. The aim of this experiment was to compare the effects of dietary supplementation of hesperidin, naringin and quercetin on laying hen performance, egg quality and egg yolk lipid and protein profiles. 2. A total of 96 Lohmann White laying hens weighing an average of 1500 g at 28 weeks of age were randomly assigned to a basal diet and the basal diet supplemented (0.5 g/kg) with either hesperidin, naringin or quercetin. Each treatment was replicated in 6 cages in an 8-week experimental period. Data were analysed using one-way analysis of variance. 3. None of the dietary flavonoids affected laying performance and eggshell quality. Hesperidin and quercetin supplementations decreased albumen and yolk indexes. 4. As compared to the control group, egg yolk cholesterol content decreased and egg yolk protein content increased in response to dietary hesperidin and quercetin supplementation. The mean egg yolk cholesterol (mg/g) and protein (g/100 g) contents were 10.08/14.28, 16.12/14.08, 14.75/15.04 and 15.15/14.85 for the control group and groups supplemented with naringin, hesperidin and quercetin, respectively. 5. Egg yolk lipid and protein profiles were variable. 6. In conclusion, dietary supplementation of hesperidin or quercetin could be used in the diets during the early laying period to reduce egg yolk cholesterol and increase egg yolk protein, which may be attractive to consumers.

This study was conducted to evaluate the effects of zinc methionine (Zn-Met) supplementation on the performance, egg quality, antioxidant status and some biochemical parameters of blood serum in laying hens from 22 to 34 weeks of age. A total of 120 Hisex Brown laying hens of 22-week-old were randomly allocated into five treatments with six cage replicates for each (four hens/replicate). Dietary treatments consisted of the basal diet with no Zn-Met supplementation (control group) and basal diet supplemented with 25, 50, 75 or 100 mg Zn-Met/kg diet. No significant differences were observed on body weight, body weight gain or feed conversion ratio due to dietary Zn-Met supplementation. However, highly significant impact was observed on daily feed intake. Egg number, egg weight and egg mass were increased in the group fed diet supplemented with the highest level of Zn-Met (100 mg/kg of diet) as compared to other groups. All egg quality traits were statistically (p > .05 or .01) affected as a response to dietary Zn-Met supplementation except egg shape index, shell percentage and yolk index. In comparison with the control group, dietary supplementation of 25, 50, 75 or 100 mg Zn-Met/kg decreased serum triglyceride and LDL-cholesterol levels. Serum cholesterol level was increased with all dietary levels of Zn-Met in comparison with the control group. Dietary Zn-Met supplementation increased the serum content of zinc, where the highest values were recorded with 50 and 100 mg Zn-Met/kg diet. Dietary Zn-Met levels did not affect the antioxidant indices in blood serum except for the activity of copper-zinc superoxide dismutase (Cu-Zn-SOD). The activity of Cu-Zn-SOD was increased with Zn-Met supplementations with no differences among supplemental zinc levels. It is concluded that dietary Zn-Met supplementation reduced serum triglyceride, LDL-cholesterol and increased Zn status and resulted in promoting antioxidant ability of laying hens, and the addition of 100 mg Zn

Summary Fermented grains of buckwheat, oat, embryo rice and wheat, which were prepared by solid-state fermentation with Antrodia salmonea, and the mycelium was used to substitute 7% of wheat flour to make bread. No difference in proximate composition, texture profile and contents of non-volatile taste components was observed among bread samples. White bread and bread supplemented with mycelium and fermented grains looked different. Bread supplemented with fermented grains had similar thermal properties, which differed from those of white bread and bread supplemented with mycelium. Bread supplemented with fermented grains contained substantial mass fractions (on dry mass basis) of adenosine (0.92–1.96 µg/g), ergosterol (24.53–30.12 µg/g), ergothioneine (2.16–3.18 µg/g) and γ-aminobutyric acid (2.20–2.45 µg/g). In addition, bread supplemented with mycelium contained lovastatin (0.43 µg/g). White bread and bread supplemented with fermented grains had similar sensory results. Overall, fermented grains could be incorporated into bread to provide beneficial effects. PMID:27904408

One experiment was conducted to evaluate the effects of guanidinoacetic acid (GAA) supplementation in broilers fed corn or sorghum-based diets on live performance, carcass and cut up yields, meat quality, and pectoral myopathies. The treatments consisted of corn or sorghum-based diets with or without the addition of GAA (600 g/ton). A total of 800 one-d-old male Ross 708 broiler chicks were randomly placed in 40 floor pens with 10 replicates (20 birds per pen) per each of the four treatments. At hatch, 14, 35, and 50 d, BW and feed intake were recorded. BW gain and FCR were calculated at the end of each phase. Four broilers per pen were selected and slaughtered at 51d and 55d of age to determine carcass and cut up yields, meat quality and myopathies (spaghetti muscle, white striping, and wooden breast) severity in the Pectoralis major. Data were analyzed as a randomized complete block design in a 2 × 2 factorial arrangement with grain type and GAA supplementation as main effects. At 50 d, diets containing GAA improved (P broilers fed corn diets with GAA had higher breast meat yield (P 0.05) by GAA supplementation at any slaughter ages. However, GAA decreased (P broilers supplemented with GAA had double (P broilers fed non-supplemented diets, therefore reducing the severity of this myopathy. In conclusion, GAA supplementation improved broiler live performance in broilers raised up to 50 d independently of grain source, increased breast meat yield in corn-based diets and reduced the severity of wooden breast myopathy.

Forty-eight castrated male goats were used to determine the effects of feeding green tea by-products (GTB) on growth performance, meat quality, blood metabolites and immune cell proliferation. Experimental treatments consisted of basal diets supplemented with four levels of GTB (0%, 0.5%, 1.0% or 2.0%). Four replicate pens were assigned to each treatment with three goats per replicate. Increasing dietary GTB tended to linearly increase the overall average weight gain and feed intake (p = 0.09). Water holding capacity, pH and sensory attributes of meat were not affected by GTB supplementation, while cooking loss was reduced both linearly and quadratically (p goat meat were improved by GTB supplementation. Increasing dietary GTB quadratically increased protein and decreased crude fat (p goat meat.

Supplements of gypsum (calcium source), pumice (silicon source) and pumice sulfate (silicon and calcium source) into substrates for oyster mushrooms (Pleurotus ostreatus) were searched for their effects on production as well as qualities of fresh and canned mushrooms. The addition of pumice up to 30% had no effect on total yield, size distribution and cap diameters. The supplementation of gypsum at 10% decreased the total yield; and although gypsum at 5% did not affect total yield, the treatment increased the proportion of large-sized caps. High content (>10%) of pumice sulfate resulted in the lower yield. Calcium and silicon contents in the fruit bodies were not influenced by supplementations. The centrifugal drip loss values and solid content of fresh mushrooms, and the percentage of weight gained and firmness of canned mushrooms, cultivated in substrates supplemented with gypsum, pumice and pumice sulfate were significantly (p≤0.05) higher than those of the control. Scanning electron micrographs revealed the more compacted hyphae of mushroom stalks supplemented with silicon and/or calcium after heat treatment, compared to the control. Supplementation of P. ostreatus substrates with 20% pumice was the most practical treatment because it showed no effect on yield and the most cost-effective.

2011-01-01
Rice bran, a by-product obtained during polishing of un-milled rice, contains a large quantity of essential nutrients such as minerals, vitamins, fiber, amino acids and antioxidants. Supplementation of rice bran in cookies can improve their nutritional value. In the present study, cookies were prepared from wheat flour with supplementation of rice bran at the rate of 5, 10, 15 and 20 percent. The rice bran was stabilized with acid and dry heat treatment before supplementation. Chemical analysis of the cookies revealed that there was no significant difference in chemical and physical properties of cookies supplemented with acid stabilized rice bran (ASRB) and heat stabilized rice bran (HSRB). The moisture, crude protein, fat and mineral contents were significantly increased with the increment of rice bran. Average width, thickness and spread factor of cookies also increased with the increase in percentage of rice bran. Sensory evaluation of cookies showed that scores for color of cookies decreased significantly with increase in level of rice bran and sensory scores were significantly higher in the cookies prepared with HSRB. However the decrease was non-significant at 10 percent level of substitution. Highest scores for overall acceptability of supplemented cookies was recorded at 15 percent level of substitution as compared to other treatments. Hence it is concluded from the results that supplementation of HSRB at the rate of 10 percent is more suitable for production of rice bran supplemented cookies. (author)

Grid is one of the potential architectures of the coming years to support both the research and the commercial environment. Quality assurance techniques need both to adapt to these new architectures and exploit them to improve its effectiveness. Software quality is a key issue in the Digital Era: Industries as well as Public Administrations devote time to check and verify the quality of ICT products and services supplied. The definition of automatic measurement of quality metrics is a key point for implementing effective QA methods. In this paper we propose a quality certification model, named Grid-based Quality Certification Model (GQCM), that uses automatically calculable metrics to asses the quality of software applications; this model has been developed within the ETICS SSA4 activities and exploit grid technology for full automation of metrics calculation. It is however designed to be generic enough such that it can be implemented using any automatic build and test tool. (Author)

Vitamin C supplementation may help reduce the risk of pregnancy complications such as pre-eclampsia, intrauterine growth restriction and maternal anaemia. There is a need to evaluate the efficacy and safety of vitamin C supplementation in pregnancy. To evaluate the effects of vitamin C supplementation, alone or in combination with other separate supplements on pregnancy outcomes, adverse events, side effects and use of health resources. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (31 March 2015) and reference lists of retrieved studies. All randomised or quasi-randomised controlled trials evaluating vitamin C supplementation in pregnant women. Interventions using a multivitamin supplement containing vitamin C or where the primary supplement was iron were excluded. Two review authors independently assessed trials for inclusion and risk of bias, extracted data and checked them for accuracy. Twenty-nine trials involving 24,300 women are included in this review. Overall, 11 trials were judged to be of low risk of bias, eight were high risk of bias and for 10 trials it was unclear. No clear differences were seen between women supplemented with vitamin C alone or in combination with other supplements compared with placebo or no control for the risk of stillbirth (risk ratio (RR) 1.15, 95% confidence intervals (CI) 0.89 to 1.49; 20,038 participants; 11 studies; I² = 0%; moderate quality evidence), neonatal death (RR 0.79, 95% CI 0.58 to 1.08; 19,575 participants; 11 studies; I² = 0%), perinatal death (average RR 1.07, 95% CI 0.77 to 1.49; 17,105 participants; seven studies; I² = 35%), birthweight (mean difference (MD) 26.88 g, 95% CI -18.81 to 72.58; 17,326 participants; 13 studies; I² = 69%), intrauterine growth restriction (RR 0.98, 95% CI 0.91 to 1.06; 20,361 participants; 12 studies; I² = 15%; high quality evidence), preterm birth (average RR 0.99, 95% CI 0.90 to 1.10; 22,250 participants; 16 studies; I² = 49%; high quality evidence

To counter the ill effects of synthetic dyes, bacterial pigment production as an alternative is now one of the promising and emerging fields of research. This study was conducted to evaluate the applicability of Deinococcus genus on the egg quality traits in laying hens. In study I, 24 single comb White Leghorn layers were fed with various 1 wt % Deinococcus bacterial strains for 10 d. In study II, 84 brown Hendrix layers were fed with one of 4 diets containing 0, 0.2, 1, or 5 wt % Deinococcus sp. GKB-Aid 1995 powder for 12 wk. In study III, 60 White Leghorn laying hens were fed either with or without 1 wt % Deinococcus sp. GKB-Aid 1995 powder, 1 wt % Deinococcus sp. GKB-Aid 1995 granules, or 1 wt % Deinococcus sp. GKB-Aid 1995 oily granules for 10 successive d. In all of the experiments, feeding Deinococcus powder did not affect egg quality traits except for the yolk color. In particular, supplementation with all Deinococcus powder treatments changed the yolk color (P 1995. Moreover, longer supplementation of Deinococcus sp. GKB-Aid 1995 in study II had a significant effect on feed conversion ratio. With these findings under consideration, the present study suggests that the Deinococcus species, especially Deinococcus sp. GKB-Aid 1995, can be an excellent candidate for improving egg yolk color in laying hens. © 2017 Poultry Science Association Inc.

2014-01-01
Full Text Available The objective of this study was to evaluate the performance, the carcass and meat characteristics of ewes supplemented with magnesium oxide. Eighteen 6-year-old Santa Ines ewes were used in a completely randomized experimental design, where three levels of supplementation (0.0, 0.1 and 0.2% magnesium oxide in the concentrate were tested, with six replicates. Final weight, weight gain, feed intake and feed conversion were not affected by levels of magnesium supplementation. Hot and cold carcass weights showed linear increasing and quadratic responses, respectively, according to supplementation with magnesium. Carcass measurements such as length, depth, and measures of arm and leg were not affected by supplementation. Depth and width of the longissimus muscle and rib-eye area were not affected; however, marbling and ether extract increased linearly with supplementation. Water loss and color were not affected. Lipid oxidation and shear force were not affected by supplementation, while the myofibrillar fragmentation index showed a quadratic regression. There was a linear decrease in pH with magnesium supplementation. Supplementation with magnesium can improve carcass and meat pH, but can act negatively by increasing the amount of marbling and ether extract of meat.

Sixty Duroc × Large White × Landrace pigs with an average initial BW of 77.1 ± 1.3 kg were used to investigate the effects of dietary supplementation with arginine and glutamic acid on growth performance, carcass traits, and meat quality in growing-finishing pigs. The animals were randomly assigned to 1 of 5 treatment groups (12 pigs/group, male:female ratio 1:1). The pigs in the control group were fed a basal diet (basal diet group), and those in the experimental groups were fed the basal diet supplemented with 2.05% -alanine (isonitrogenous group), 1.0% -arginine (Arg group), 1% glutamic acid + 1.44% -alanine (Glu group), or 1.0% -arginine + 1.0% glutamic acid (Arg+Glu group). After a 60-d period of supplementation, growth performance, carcass traits, and meat quality were evaluated. The results showed no significant differences ( > 0.05) in growth performance and carcass traits of the pigs in the Arg group relative to the basal diet group; however, the longissimus dorsi (LD) muscle and back fat showed a decrease ( 0.05) on the final BW, phase 2 ADFI, and average daily weight gain in pigs but decreased ( acid composition without affecting growth performance and s.c. fat in pigs, providing a novel strategy to enhance meat quality in growing-finishing pigs.

Objective To understand Americans' attitudes concerning health information technology's (IT's) potential to improve health care and differences in those attitudes based on demographics and technological affinity. Data Sources/Study Setting A random-digit-dial sample with known probability of selection for every household in the United States with a telephone, plus a supplemental sample of cell phone users. Telephone interviews were conducted from August 2009 through November 2009. Study Design Data were analyzed to present univariate estimates of Americans' opinions of health IT, as well as multivariate logistic regressions to assess hypotheses relating individuals' characteristics to their opinions. Characteristics used in our model include age, race, ethnicity, gender, income, and affinity to technology. Findings A large majority (78 percent) favor use of electronic medical records (EMRs); believe EMRs could improve care and reduce costs (78 percent and 59 percent, respectively); believe benefits of EMR use outweigh privacy risks (64 percent); and support health care information sharing among providers (72 percent). Regression analyses show more positive attitudes among those with higher incomes and greater comfort using electronic technologies. Conclusion The findings suggest that American's believe that health IT adoption is an effective means to improve the quality and safety of health care. PMID:21275986

Vitamin supplementation for preventing miscarriage.
Balogun, Olukunmi O; da Silva Lopes, Katharina; Ota, Erika; Takemoto, Yo; Rumbold, Alice; Takegata, Mizuki; Mori, Rintaro
2016-05-06
Miscarriage is a common complication of pregnancy that can be caused by a wide range of factors. Poor dietary intake of vitamins has been associated with an increased risk of miscarriage, therefore supplementing women with vitamins either prior to or in early pregnancy may help prevent miscarriage. The objectives of this review were to determine the effectiveness and safety of any vitamin supplementation, on the risk of spontaneous miscarriage. We searched the Cochrane Pregnancy and Childbirth Group Trials Register (6 November 2015) and reference lists of retrieved studies. All randomised and quasi-randomised trials comparing supplementation during pregnancy with one or more vitamins with either placebo, other vitamins, no vitamins or other interventions. We have included supplementation that started prior to conception, periconceptionally or in early pregnancy (less than 20 weeks' gestation). Three review authors independently assessed trials for inclusion, extracted data and assessed trial quality. We assessed the quality of the evidence using the GRADE approach. The quality of evidence is included for numerical results of outcomes included in the 'Summary of findings' tables. We included a total of 40 trials (involving 276,820 women and 278,413 pregnancies) assessing supplementation with any vitamin(s) starting prior to 20 weeks' gestation and reporting at least one primary outcome that was eligible for the review. Eight trials were cluster-randomised and contributed data for 217,726 women and 219,267 pregnancies in total.Approximately half of the included trials were assessed to have a low risk of bias for both random sequence generation and adequate concealment of participants to treatment and control groups. Vitamin C supplementation There was no difference in the risk of total fetal loss (risk ratio (RR) 1.14, 95% confidence interval (CI) 0.92 to 1.40, seven trials, 18,949 women; high-quality evidence); early or late miscarriage (RR 0.90, 95% CI 0.65 to 1

Full Text Available This study was carried out to evaluate the effects of dietary trace mineral levels and sources on egg quality parameters of second-cycle semi-heavy layers. A number of 360 72-week-old layers were submitted to forced molting. Upon return of lay (83 weeks of age, birds were distributed according to a completely randomized experimental design of six treatments with six replicates of 10 birds each. The control treatment consisted of 0.10% dietary supplementation of trace minerals from inorganic sources, which was proportionally replaced by five levels (110, 100, 90, 80, 70% of an organic trace mineral supplement containing 30, 30, 40, 6, 0.61, and 0.3 g/kg product of Zn, Fe, Mn, Cu, I, and Se, respectively. All diets contained equal protein, energy, and amino acid levels. Every 28 days of the experimental period (112 days four eggs per replicate were collected for egg quality evaluation. The following parameters were evaluated: specific gravity, yolk, albumen and eggshell percentages, yolk index, Haugh units, and eggshell thickness and breaking strength. One sample per replicate, consisting of the pool of the yolks of three eggs collected at the end of each experimental period, was used to assess protein and mineral (Ca, P, Cu, Fe, Mn, and Zn contents. The results were submitted to ANOVA, and means to the test of Tukey at 5% significance level. The evaluated trace mineral levels and sources did not influence any of the studied egg quality parameters. It was concluded that reducing organic trace mineral supplementation in up to 70% relative to 100% inorganic trace mineral supplementation does not affect egg parameters and therefore, can be applied to the diet of semi-heavy layers in their second cycle of lay.

Factors affecting the adoption of quality assurance technologies in healthcare.
Storey, John
2013-01-01
In the light of public concern and of strong policy emphasis on quality and safety in the nursing care of patients in hospital settings, this paper aims to focus on the factors affecting the adoption of innovative quality assurance technologies. Two sets of complementary literature were mined for key themes. Next, new empirical insights were sought. Data gathering was conducted in three phases. The first involved contact with NHS Technology Hubs and other institutions which had insights into leading centres in quality assurance technologies. The second phase was a series of telephone interviews with lead nurses in those hospitals which were identified in the first phase as comprising the leading centres. The third phase comprised a series of face to face interviews with innovators and adopters of healthcare quality assurance technologies in five hospital trusts. There were three main sets of findings. First, despite the strong policy push and the templates established at national level, there were significant variations in the nature and robustness of the quality assurance toolkits that were developed, adapted and adopted. Second, in most of the adopting cases there were important obstacles to the full adoption of the toolkits that were designed. Third, the extent and nature of the ambition of the developers varied dramatically - some wished to see their work impacting widely across the health service; others had a number of different reasons for wanting to restrict the impact of their work. The general concerns about front-line care and the various inquiries into care quality failures emphasise the need for improved and consistent care quality assurance methodologies and practice. The technology adoption literature gives only partial insight into the nature of the challenges; this paper offers specific insights into the factors inhibiting the full adoption of quality assurance technologies in ward-based care.

SUPPLIER SELECTION STRATEGY AND MANUFACTURING FLEXIBILITY: IMPACT OF QUALITY AND TECHNOLOGY ROADMAPS
Directory of Open Access Journals (Sweden)
Muhamad Jantan
2006-01-01
Full Text Available The study evaluates the relationship between technology, quality, cost and delivery performance-based, supplier selection strategies, and manufacturing flexibilities namely, product flexibility, launch flexibility, and volume flexibility. Moreover, the moderating impact of supplier management strategies, namely quality roadmap and technology roadmap on the above relationships were also explored. The data for the study was drawn from a sample of companies listed in the factory directory published by the Penang Development Corporation (PDC. A postal survey of 120 manufacturers provided a return of 92 usable responses. The results reveal that the selection of suppliers based on technological and quality performance positively affects all the three dimensions of manufacturing flexibility, with complementary effects of good technology and quality roadmaps. Technology and quality roadmaps act as predictors for product and volume flexibilities. However, when launch flexibility is the focus, both technology and quality roadmaps moderate the impact of supplier selection strategies. Details of the findings, theoretical and practical implications, and the research limitation are discussed.

Nutritional supplements for people being treated for active tuberculosis
Grobler, Liesl; Nagpal, Sukrti; Sudarsanam, Thambu D; Sinclair, David
2016-01-01
Background Tuberculosis and malnutrition are linked in a complex relationship. Tuberculosis may cause undernutrition through increased metabolic demands and decreased intake, and nutritional deficiencies may worsen the disease, or delay recovery by depressing important immune functions. At present, there is no evidence-based nutritional guidance for adults and children being treated for tuberculosis. Objectives To assess the effects of oral nutritional supplements in people being treated with antituberculous drug therapy for active tuberculosis. Search methods We searched the Cochrane Infectious Disease Group Specialized Register, Cochrane Central Register of Controlled Trials (CENTRAL; Issue 1, 2016), MEDLINE (from 1946 to 4 February 2016), EMBASE (from 1980 to 4 February 2016), LILACS (from 1982 to 4 February 2016), the metaRegister of Controlled Trials (mRCT), the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP), and the Indian Journal of Tuberculosis up to 4 February 2016, and checked the reference lists of all included studies. Selection criteria Randomized controlled trials that compared any oral nutritional supplement given for at least four weeks with no nutritional intervention, placebo, or dietary advice only for people being treated for active tuberculosis. The primary outcomes of interest were all-cause death, and cure at six and 12 months. Data collection and analysis Two review authors independently selected trials for inclusion, and extracted data and assessed the risk of bias in the included trials. We presented the results as risk ratios (RR) for dichotomous variables, and mean differences (MD) for continuous variables, with 95% confidence intervals (CIs). Where appropriate, we pooled data from trials with similar interventions and outcomes. We assessed the quality of the evidence using the Grading of Recommendation Assessment, Development and Evaluation (GRADE) approach. Main results Thirty-five trials

Leveraging Health Information Technology to Improve Quality in Federal Healthcare.
Weigel, Fred K; Switaj, Timothy L; Hamilton, Jessica
2015-01-01
Healthcare delivery in America is extremely complex because it is comprised of a fragmented and nonsystematic mix of stakeholders, components, and processes. Within the US healthcare structure, the federal healthcare system is poised to lead American medicine in leveraging health information technology to improve the quality of healthcare. We posit that through developing, adopting, and refining health information technology, the federal healthcare system has the potential to transform federal healthcare quality by managing the complexities associated with healthcare delivery. Although federal mandates have spurred the widespread use of electronic health records, other beneficial technologies have yet to be adopted in federal healthcare settings. The use of health information technology is fundamental in providing the highest quality, safest healthcare possible. In addition, health information technology is valuable in achieving the Agency for Healthcare Research and Quality's implementation goals. We conducted a comprehensive literature search using the Google Scholar, PubMed, and Cochrane databases to identify an initial list of articles. Through a thorough review of the titles and abstracts, we identified 42 articles as having relevance to health information technology and quality. Through our exclusion criteria of currency of the article, citation frequency, applicability to the federal health system, and quality of research supporting conclusions, we refined the list to 11 references from which we performed our analysis. The literature shows that the use of computerized physician order entry has significantly increased accurate medication dosage and decreased medication errors. The use of clinical decision support systems have significantly increased physician adherence to guidelines, although there is little evidence that indicates any significant correlation to patient outcomes. Research shows that interoperability and usability are continuing challenges for

2015-12-01
In the present study, the effect of feed Se supplementation on the Se content of raw milk and mozzarella cheese as well as the effect on cheese quality and functionality were determined. The Se milk was produced by supplying dairy cow feed with Se yeast (0.3mg of Se/kg of dry matter), resulting in a Se concentration in milk of 35.81μg/L. The fat, casein, and whey protein of Se milk were separated by ultracentrifugation, and the Se content was determined by atomic absorption spectroscopy. The Se distribution in different milk fractions of fat, casein, and whey protein were 9.82, 45.56, and 44.62%, respectively. The Se mozzarella cheese was made by Se milk, and the composition and texture of Se cheese did not significantly differ from that of the control. However, the functional properties (meltability, flowability, and stretchability) of the Se cheese were better after 8 wk of storage. Moreover, the pH and water activity were lower in Se cheese, which decreased the total plate count. The Se content in mozzarella cheese was 4 fold higher than that in milk, and Se was found in the whey, hot water, and brine collected during cheesemaking. Organic and inorganic Se was found in the Se cheese after 8 wk of storage, and most Se peptides detected after storage were Se-Met and Se-Cys. The results of this study show that feed Se supplementation can improve the Se content of milk and cheese without affecting mozzarella cheese quality.

Nutritional and technological quality of the durum wheat
Directory of Open Access Journals (Sweden)
Zina Flagella
Full Text Available Durum wheat quality is a complex system that combines yield characteristics, cultivation conditions and certification requirements. In this review, the technological and nutritional aspects of grain quality were evaluated in relation to the influence of climate and agronomic practices. In particular, the technological quality was investigated with regard to the kind of processed product (pasta, bread, couscous, burghul. The influence of nitrogen and sulphur nutrition, temperature, water regime and organic farming on grain quality was evaluated. Furthermore, the nutritional characteristics of durum wheat related to starch, proteins, lipids, vitamins, fibres and mineral ions content were examined. Special focus was on the antioxidant activity capable of preventing chronic and degenerative diseases thanks to the high content in bioactive compounds, as phenols, tocols, carotenoids and fibres in whole grain. In the light of the new direction of the Community agricultural policy and of the growing interest in human nutrition, two prospects for development of the durum wheat sector were delineated: i developing certified products (PGI, PDO and organic; ii promoting production and processing technologies aimed at increasing the level of bioactive compounds in durum wheat grain and its by-products.

Technology and quality of life outcomes.
Hacker, Eileen Danaher
2010-02-01
To discuss recent technological advances in quality of life (QOL) data collection and guidance for use in research and clinical practice. The use of telephone-, computer-, and web/internet-based technologies to collect QOL data, reliability and validity issues, and cost will be discussed, along with the potential pitfalls associated with these technologies. Health care literature and web resources. Technology has provided researchers and clinicians with an opportunity to collect QOL data from patients that were previously not accessible. Most technologies offer a variety of options, such as language choice, formatting options for the delivery of questions, and data management services. Choosing the appropriate technology for use in research and/or clinical practice primarily depends on the purpose for QOL data collection. Technology is changing the way nurses assess QOL in patients with cancer and provide care. As stakeholders in the health care delivery system and patient advocates, nurses must be intimately involved in the evaluation and use of new technologies that impact QOL and/or the delivery of care.

Effects of nitrogen supplementation associated with different levels of starch on voluntary intake, digestibility, and rumen and metabolic characteristics of cattle fed low-quality tropical forage ( Brachiaria decumbens hay, 7.4% crude protein, CP) were evaluated using ruminal and abomasal cannulated steers. Five European×Zebu young bulls (186 kg body weight, BW) were distributed according to a 5×5 Latin square. The following treatments were evaluated: control, supplementation with 300 g CP/d (0:1), supplementation with 300 g starch/d and 300 g CP/d (1:1), supplementation with 600 g starch/d and 300 g CP/d (2:1), and supplementation with 900 g starch/d and 300 g CP/d (3:1). A mixture of nitrogenous compounds provided 1/3 from true protein (casein) and 2/3 from non-protein nitrogen (mixture of urea and ammonium sulphate, 9:1) was used as the nitrogen supplement. In order to supply energy a unique source of corn starch was used. Supplements increased (p0.05) forage intake. There was a cubic effect (pdigestibility, but did not affect (p>0.05) neutral detergent fibre corrected for ash and protein (NDFap) digestibility. There was a positive linear effect (pdigestibility. Total NDFap digestibility was not affected (p>0.05) by the amount of supplemental starch. Ruminal ammonia nitrogen concentrations were higher (p<0.05) in supplemented animals, however, a negative linear effect (p<0.05) of amount of starch was observed. Supplements increased (p<0.05) the nitrogen balance (NB) and efficiency of nitrogen utilization. These effects were attributed to increased body anabolism, supported by higher (p<0.05) serum concentration of insulin-like growth factor 1. Increasing the amount of starch tended (p<0.06) to linearly increase the NB. In spite of this, there was a highest NB value for the 2:1 starch:CP ratio amongst the treatments with supplementation. Nitrogen supplementation in cattle fed low-quality tropical forage increases nitrogen retention in the animal's body. An

The experimental diets consisted of five levels of FB: 0% (control, 25%, 50%, 75% and 100%, substituting soybean meal (SBM, and two levels of enzyme supplementation (0 or 250 mg/kg. Each dietary treatment was assigned to four replicate groups and the experiment lasted 22 weeks. A positive relationship (P 0.05. The main effect of FB levels replacing for SBM affected (P < 0.05 yolk and shell percentages, yolk index, yolk to albumen ratio, shell thickness and egg shape index. It can be concluded that FB and enzyme supplementation could be included in hens diet at less than 50% instead of SBM to support egg productive performance, however higher raw FB levels negatively affected egg production indices and quality.

Background The purchase of dietary supplements (DS) via the Internet is increasing worldwide as well as in the Czech Republic. Objective The aim of the study is to evaluate the quality of information on DS available on the Internet. Setting Czech websites related to dietary supplements. Methods A cross-sectional study was carried out involving the analysis of information placed on the websites related to the 100 top-selling DS in the Czech Republic in 2014, according to IMS Health data. Main outcome measure The following criteria were evaluated: contact for the manufacturer, recommended dosage, information on active substances as well as overall composition, permitted health claims, % of the daily reference intake value (DRIV) for vitamins and minerals, link for online counseling, pregnancy/breastfeeding, allergy information, contraindications, adverse reactions, and supplement-drug interactions (some criteria were evaluated from both points of view). Results A total of 199 web domains and 850 websites were evaluated. From the regulatory point of view, all the criteria were fulfilled by 11.3% of websites. Almost 9% of the websites reported information referring to the treatment, cure, or prevention of a disease. From the clinical point of view, all the criteria were only met by one website. Conclusions The quality of information related to DS available on the Internet in the Czech Republic is quite low. The consumers should consult a specialist when using DS purchased online.

1. The effects of dietary vitamin E (DL-alpha-tocopheryl acetate) on carcase and meat quality, oxidative stability, fatty acid composition of muscle lipids, and gene expression related to lipid metabolism were studied in Beijing-you chickens. 2. A total of 360 female birds were distributed among 6 treatments, containing 6 replicates, each of 10 birds. The feed for each treatment was supplemented with vitamin E (0, 10, 50, 100, 150, or 200 mg/kg feed). At 120 d, 30 birds from each treatment were slaughtered to examine the effect of dietary vitamin E supplementation on evaluated traits. 3. The results showed that supplemental vitamin E in diet significantly increased alpha-tocopherol contents of breast and thigh muscles, reduced the drip loss and improved tenderness but did not influence carcase yield, meat colour or pH value 24 h after slaughter. 4. Thiobarbituric acid reactive substance (TBARS) values decreased with increase in dietary vitamin E, and the addition of 100 mg/kg or more vitamin E had a beneficial effect on oxidative stability as indicated by TBARS values during storage up to 7 d. 5. Dietary vitamin E supplementation significantly altered fatty acid composition of breast muscle. Supplementing with 200 mg/kg vitamin E led to lower saturated fatty acids and greater polyunsaturated fatty acids proportions in breast muscle than control and 10 mg/kg vitamin E treatments. 6. Vitamin E supplementation significantly inhibited expression of the cytosolic phospholipase A(2) gene (cPLA(2)) in breast muscle, while enhancing that of the peroxisome proliterator-activated receptor beta (PPAP-beta) and heart fatty acid binding protein genes (H-FABP). The results indicate that dietary supplementation with vitamin E increased lipid stability in muscle and improved meat quality and fatty acid composition, probably by its influence on the expression of genes related to lipid metabolism.

The objective of this study was to determine if a diet supplemented simultaneously with vitamins C and E would alleviate the negative effects of heat stress, applied between 28 and 42 days of age, on performance, carcass and meat quality traits of broiler chickens. A total of 384 male broiler chickens were assigned to a completely randomized design, with a 2×3 factorial arrangement (diet with or without vitamin supplementation and two ambient temperatures plus a pair-feeding group) and 16 replicates. Chickens were kept in thermoneutral conditions up to 28 days of age. They were then housed in groups of four per cage, in three environmentally controlled chambers: two thermoneutral (22.5 and 22.6°C) and one for heat stress (32°C). Half the chickens were fed a diet supplemented with vitamins C (257 to 288 mg/kg) and E (93 to 109 mg/kg). In the thermoneutral chambers, half of the chickens were pair-fed to heat stressed chickens, receiving each day the average feed intake recorded in the heat stress chamber in the previous day. Meat physical quality analyses were performed on the pectoralis major muscle. No ambient temperature×diet supplementation interaction effects were detected on performance, carcass, or meat quality traits. The supplemented diet resulted in lower growth performance, attributed either to a carry-over effect of the lower initial BW, or to a possible catabolic effect of vitamins C and E when supplemented simultaneously at high levels. Heat stress reduced slaughter and carcass weights, average daily gain and feed intake, and increased feed conversion. Growth performance of pair-fed chickens was similar to that of heat stressed chickens. Exposure to heat stress increased carcass and abdominal fat percentages, but reduced breast, liver and heart percentages. Pair-fed chickens showed the lowest fat percentage and their breast percentage was similar to controls. Heat stress increased meat pH and negatively affected meat color and cooking loss. In pair

Full Text Available The objective of present study was to determine the effects of β-mannanase-based enzyme (Hemicell® on productive performance and egg quality in diets containing graded levels of Whole date waste (WDW fed to laying hens. A total of 336 Hy-line leghorn hens after production peak were randomly divided into 56 cages. Eight iso-energetic and iso-nitrogenous experimental diets in a 4 × 2 factorial arrangement including four levels of WDW (0, 10, 20 and 30% and 2 concentrations of supplemental β-mannanase (0 or 0.06 % were prepared. Each dietary treatment was fed to 7 cages (6 birds/cage from 32 to 38 wk of age. During the experiment, daily egg production, egg weight and feed intake were measured. At the 6th wk, egg quality traits were also recorded. The results showed that there was no interaction between WDW inclusion and enzyme supplementation on performance and egg traits. Dietary supplementation of WDW more than 10% significantly decreased egg production and egg mass compared to no WDW recipient hens (control diet during the entire experiment (P. Inclusion of 30% WDW to the diet, significantly increased overall feed conversion ratio compared to the control group (P. The treatment with 20 and 30% WDW also resulted in lower eggshell thickness as compared to 10% WDW (P. The dietary inclusion of 10% WDW also increased yolk index as compared to the control and 30% WDW groups (P. Enzyme supplementation had no significant effect on productive performance as well as egg quality characteristics. Based on the results of this experiment, it can be concluded that WDW could be included to laying hens diets up to 10% with no deleterious effects on performance and egg quality characteristics.

Full Text Available Effect of dairy proteins on gluten-free dough behavior, and nutritional and technological properties of gluten-free bread was evaluated. Experimental doughs, containing dairy powders, showed low consistency. Obtained gluten-free breads were rich in proteins, and, regarding the energy value delivered by proteins, they could be considered as a source of proteins or high in proteins. Applied dairy proteins affected the technological properties of experimental breads causing a significant (p < 0.05 increase of the specific volume, crust darkening, and crumb lightness, depending on the dairy supplementation level, rather than the protein type. Dairy proteins incorporated at a 12% level, significantly (p < 0.05 decreased the hardness; nevertheless, the highest amount of proteins tested led to the opposite effect. These results indicate that milk proteins tested could be successfully added to gluten-free bread with beneficial effects on technological and nutritional properties.

Psoriasis patients are often displeased with traditional medical treatments and they may self-prescribe dietary supplements as an alternative or complementary treatments. We aimed to investigate the prevalence of self-medication of dietary supplements among psoriasis and non-psoriasis cases and its impact on disease severity and quality of life. This case-control study evaluated 252 records of psoriasis patients and 245 non-psoriasis cases. Dietary supplementation over last 30days and characteristics, including age, age at onset of disease, co-morbidities, smoking and education were recorded. Psoriasis area and severity index (PASI) and dermatology quality of life index (DLQI) were calculated. P value less than 0.05 was considered as significant level. This study consisted 138 psoriasis (females; 54) and 138 non-psoriasis cases (females; 50), aged between 21 and 91 years. Among psoriasis patients, 72% reported using at least one of dietary supplements, which was different from non-psoriasis cases (25.36%, P=0.01). Multivitamin/mineral supplements (MVM) were the most frequent used dietary supplements (26.81%) and the most common reasons for the consumption of these supplements were to maintain and improve health. The consumption of folic acid (21.73%), omega-3 fatty acids or fish oil (10.14%), herbs (12.31%) and vitamin E (1.44%) had the most frequencies after MVM. No significant differences in PASI and DLQI were found among patients with consumption of different supplements (P>0.05). There was non-significant and negative correlation between education and use of supplements (P=0.21, r=-0.02). Self-medicating of MVM over last 30days was prevalent among studied psoriasis patients. They took dietary supplements in order to improve and maintain their health. Copyright © 2017 Elsevier Ltd. All rights reserved.

Full Text Available In a project coordinated by the International Agency for Research on Cancer (IARC 31 experts from 11 European countries and IARC have developed supplements to the current European guidelines for quality assurance in cervical cancer screening. The supplements take into account the potential of primary testing for human papillomavirus (HPV and vaccination against HPV infection to improve cervical cancer prevention and control and will be published by the European Commission in book format. They include 62 recommendations or conclusions for which the strength of the evidence and the respective recommendations is graded. While acknowledging the available evidence for more efficacious screening using HPV primary testing compared to screening based on cytology, the authors and editors of the supplements emphasize that appropriate policy and programme organization remain essential to achieve an acceptable balance between benefit and harm of any screening or vaccination programme. A summary of the supplements and all of the graded recommendations are presented here in journal format to make key aspects of the updated and expanded guidelines known to a wider professional and scientific community.

Sewage solids were collected as 'primary settled solids' and then dried and gamma-irradiated (using 60 Co or 177 Cs) to absorbed dosage of about one magarad to minimize viable parasites and pathogenic organisms. Nutrient composition and bioassays suggested prospective usage as supplemental feed for ruminants. In a large-scale experiment, beef cows grazing poor-quality rangeland forage during late gestation-early lactation were given either no supplemental feed or cottonseed meal or experimental supplement comprised of 62% sewage solids. Supplements were provided for 13 weeks until rangeland forage quality improved seasonably. Supplemental cottenseed meal for cows improved weaning weights of calves by about 11% over unsupplemented controls; whereas, supplement with 62% sewage solids improved calf weaning weights by about 7%. Hazards or risks to animals or to human health appear to be slight when sewage solids of this type are fed as supplemental feeds to cattle in production programs of this type. (Auth.)

Four ruminally and duodenally cannulated Suffolk wether lambs (34.5 +/- 2.0 kg initial BW) were used in a 4 x 4 Latin square-designed experiment to examine the effects of ruminal protein degradability and supplementation frequency on site and extent of digestion in lambs consuming a low-quality forage diet. Wethers were fed a basal diet of mature crested wheatgrass hay (4.2% CP) for ad libitum consumption plus 1 of 4 supplements: 1) a high RDP supplement provided daily (RDP-D), 2) the high RDP supplement provided on alternate days (RDP-A), 3) a high RUP supplement provided on alternate days (RUP-A), or 4) a 50:50 mixture of the RDP and RUP supplements, provided on alternate days (MIX-A). Forage OM, N, NDF, or ADF intakes were not affected by treatment. True ruminal OM digestibility was greater (P RUP-A lambs compared with other treatments. Ruminal digestibilities of NDF and ADF were greater (P RUP had less (P RUP-A lambs exhibiting the least concentrations and least variation over time. Ruminal urease activity was not affected by treatment. Microbial N flow was not affected by treatment; however, there was an increase (P = 0.004) in microbial efficiency for RDP-D lambs. Alternate day protein supplementation with a mixture of RDP and RUP may improve digestibility in lambs consuming low-quality forage, which may be related to decreased fluctuation in ruminal ammonia concentrations as a result of greater endogenous N recycling.

This article aims to explore the relationship between technology and quality management for enhancing Thai hospital service quality. The paper presents the findings of an exploratory study that investigates service quality from the customer and service provider perception. In-depth interviews were conducted with respondents in Thai hospitals. The interviews explored service-related factors that patients and service providers perceive to be important for hospital services. The first interview group consisted of professionals as internal customers in direct contact with external customers, while the second group consisted of external customers of the same hospitals. The study's outcomes clearly suggest factors that make significant contribution to service quality. These factors can be categorized according to five SERVQUAL dimensions (reliability, responsiveness, assurance, empathy, and tangibility), although some factors required slightly different interpretation. The findings suggest that hospitals can develop an appropriate approach to their advantage, which can yield sustainable improvement in service quality as perceived by patients and professionals. Hospitals can make better quality decisions based on structured measurement and knowledge. It is recommended that managers apply this knowledge for successful implementation of activities related to service quality in their organizations.

2016-12-01
There is a growing demand for food supplements containing high amounts of vitamins, phenolic compounds and mineral content that provide health benefits. Those functional compounds have different solubility properties, and the maintenance of their compounds and the guarantee of their homogenic properties need the application of novel technologies. The quality of different drinkable functional foods after thermal processing (0.1 MPa) or high-pressure homogenization under two different conditions (80 MPa, 33 ℃ and 120 MPa, 43 ℃) was studied. Physicochemical characteristics and sensory qualities were evaluated throughout the six months of accelerated storage at 40 ℃ and 75% relative humidity (RH). Aroma and color were better maintained in high-pressure homogenization-treated samples than the thermally treated ones, which contributed significantly to extending their shelf life. The small particle size obtained after high-pressure homogenization treatments caused differences in turbidity and viscosity with respect to heat-treated samples. The use of high-pressure homogenization, more specifically, 120 MPa, provided active ingredient homogeneity to ensure uniform content in functional food supplements. Although the effect of high-pressure homogenization can be affected by the food matrix, high-pressure homogenization can be implemented as an alternative to conventional heat treatments in a commercial setting within the functional food supplement or pharmaceutical industry. © The Author(s) 2016.

Some algae are an excellent sources of vitamin B12, of special interest for vegetarian/vegan consumers, and of fucose to supplement fruit and vegetable beverages such as smoothies. Nevertheless, supplementation of smoothies with algae may lead to possible quality changes during smoothie shelf life that need to be studied. Therefore, the quality changes in fresh green smoothies supplemented (2.2%) with nine edible algae (sea lettuce, kombu, wakame, thongweed, dulse, Irish moss, nori, Spirulina and Chlorella) were studied throughout 24 days at 5 °C. The initial vitamin C content - 238.7-326.0 mg kg -1 fresh weight (FW) - of a 200 g portion of any of the smoothies ensured full coverage of its recommended daily intake, and still supplying 50-60% of the recommended intake after 7 days. Chlorella and Spirulina smoothies showed the highest vitamin B12 content (33.3 and 15.3 µg kg -1 FW, respectively), while brown algae showed fucose content of 141.1-571.3 mg kg -1 FW. These vitamin B12 and fucose contents were highly maintained during shelf life. The Spirulina supplementation of a 200 g smoothie portion ensured full coverage of the recommended vitamin B12 intake, with lower vitamin C degradation, during a shelf life of 17 days. Furthermore, thongweed and kombu are also considered as excellent fucose sources with similar shelf life. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

Two experiments were conducted to investigate the potential use of dried cassava pulp (DCP) supplemented with enzymes as an alternative feed ingredient in laying hen diets. In experiment 1, 45 laying hens (Isa Brown) aged 45 weeks were placed in individual cages to measure nutrient digestibility for 10 days. Nine dietary treatments were control and DCP as a replacement for corn at 20, 25, 30, and 35% supplemented with mixed enzymes (cellulase, glucanase, and xylanase) at 0.10 and 0.15%. Results showed that the use of DCP at 20-35% added with mixed enzymes had no negative effects on dry matter digestibility, while organic matter digestibility and nitrogen retention decreased with increased DCP up to 30-35% in diets. Both enzyme levels (0.10 and 0.15%) showed similar results on nutrient digestibility and retention. In experiment 2, a total of 336 laying hens aged 32 weeks were randomly allocated to seven dietary treatments (control and DCP-substituted diets at 20, 25, and 30%) supplemented with mixed enzymes (0.10 and 0.15%). Diets incorporated with 20-30% of DCP and supplemented with mixed enzymes at both levels had no significant effects on egg production, egg weight, feed intake, egg mass, feed conversion ratio, protein efficiency ratio, or egg quality, except for egg yolk color being decreased with an increase of DCP in diets (P digestibility, productive performance, or egg quality.

Issues in Nutrition: Dietary Supplements.
Thompson, Margaret E; Noel, Mary Barth
2017-01-01
The majority of American adults report use of one or more dietary supplements every day or occasionally. The Dietary Supplement Health and Education Act of 1994 defines dietary supplements and regulates their manufacture and distribution. One of the most commonly used supplements is vitamin D. Measurement of serum levels of vitamin D must be undertaken with the caveats that different laboratories define normal levels differently, and that there is rarely a clinical correlation with the actual level. Patients should understand that supplements should not be used to excess, as there are toxicities and other adverse effects associated with most of them. There currently is considerable research being performed on probiotics and how the gut microbiome affects health and disease states. Protein supplements may be useful in reducing mortality rates in elderly patients but they do not appear to increase quality of life. If used, protein supplements should contain essential amino acids. Casein and whey supplements, derived from dairy sources, help transport essential amino acids to tissues. Although there have been many studies investigating the role of vitamin supplements in disease prevention, there have been few conclusive positive results.

This study aimed to compare post-thaw quality of boar semen following freezing in an ostrich egg yolk lipoprotein (LPFo) extender supplemented with 0%, 0.25% and 0.50% Orvus Es Paste (OEP). Sperm assessments included total motility (TMOT), mitochondrial function (MF), plasma membrane integrity (PMI) and acrosome integrity (normal apical ridge, NAR). Considerable variations among boars and OEP treatments had a significant effect (P semen samples frozen in the absence of OEP. By contrast, lactose-LPFo-glycerol extender supplemented with either 0.25% OEP or 0.50% OEP markedly enhanced post-thaw sperm characteristics. In all boars, there were no marked differences in post-thaw sperm TMOT between the freezing extenders supplemented with 0.25% and 0.50% OEP. However, a decline in the percentage of post-thaw motile spermatozoa was more pronounced in the extender supplemented with 0.50% OEP following a 120-min incubation period. Furthermore, the proportions of frozen-thawed spermatozoa with MF, PMI and NAR acrosomes varied significantly among the boars in the OEP-supplemented extenders. The findings of this study indicate that different OEP concentrations, in the presence of ostrich egg yolk lipoproteins, could have varying effects on post-thaw sperm survival.

A total of 494 term, healthy newborn infants with unconjugated hyperbilirubinaemia were evaluated. All studies were at high risk of bias for blinding of care personnel, five studies had unclear risk of bias for blinding of outcome assessors, and most studies had unclear risk of bias in allocation concealment. There was low- to moderate-quality evidence for all major outcomes.In the comparison between IV fluid supplementation and no supplementation, no infant in either group developed bilirubin encephalopathy in the one study that reported this outcome. Serum bilirubin was lower at four hours postintervention for infants who received IV fluid supplementation (MD -34.00 μmol/L (-1.99 mg/dL), 95% CI -52.29 (3.06) to -15.71 (0.92); participants = 67, study = 1) (low quality of evidence, downgraded one level for indirectness and one level for suspected publication bias). Beyond eight hours postintervention, serum bilirubin was similar between the two groups. Duration of phototherapy was significantly shorter for fluid-supplemented infants, but the estimate was affected by heterogeneity which was not clearly explained (MD -10.70 hours, 95% CI -15.55 to -5.85; participants = 218; studies = 3; I² = 67%). Fluid-supplemented infants were less likely to require exchange transfusion (RR 0.39, 95% CI 0.21 to 0.71; RD -0.01, 95% CI -0.04 to 0.02; participants = 462; studies = 6; I² = 72%) (low quality of evidence, downgraded one level due to inconsistency, and another level due to suspected publication bias), and the estimate was similarly affected by unexplained heterogeneity. The frequencies of breastfeeding were similar between the fluid-supplemented and non-supplemented infants in days one to three based on one study (estimate on day three: MD 0.90 feeds, 95% CI -0.40 to 2.20; participants = 60) (moderate

The present study was conducted to compare the supplementation of natural (D-α-tocopherol) and synthetic (DL-α-tocopherol acetate) vitamin E on the growth performance, meat quality, muscular antioxidant capacity and genes expression related to oxidative status of broilers. A total of 144 1 day-old Arbor Acres broiler chicks were randomly allocated into 3 groups with 6 replicates of 8 birds each. Birds were given a basal diet (control group), and basal diet supplemented with either 20 IU D-α-tocopherol or DL-α-tocopherol acetate for 42 days, respectively. The results indicated that treatments did not alter growth performance of broilers (p>0.05). Compared with the control group, concentration of α-tocopherol in the breast muscle was increased by the supplementation of vitamin E (pnatural vitamin E group (pnatural vitamin E group (pnatural rather than synthetic vitamin E reduced MDA accumulation in the thigh (pnatural nor synthetic vitamin E supplementation altered muscular mRNA abundance of genes related to oxidative stress (p>0.05). It was concluded that vitamin E supplementation, especially the natural vitamin E, can enhance the retention of muscular α-tocopherol, improve meat quality and muscular antioxidant capacity of broilers.

Full Text Available ABSTRACT An experiment was conducted to determine the effect of varying dietary supplemental inclusion levels of onion and garlic mixture on semen quality characteristics of Koekoek breeder cocks aged 35-41 weeks. The experimental diets were isocaloric and isonitrogenous but with different supplemental inclusion levels of onion and garlic. A complete randomized design was used for the experiment. The three dietary supplemental levels based on garlic and onion supplemental inclusion levels were Q0 (0 g onion and 0 g garlic per 600 g DM feed, Q1 (2.5 g onion and 2.5 g garlic per 600 g DM feed, and Q2 (5 g onion and 5 g garlic per 600 g DM feed with each treatment having three replicates. A quadratic type equation was used to determine the onion and garlic levels for optimum semen quality characteristics. Daily supplementation with 5 g onion and 5 g garlic per 600 g DM feed increased progressive motile cells (%, actual life sperm count (×106/nl, and live sperm (% by 221.20%, 301.51%, and 352.43%, while 2.5 g onion and 2.5 g garlic per 600 g DM feed reduced them by 28.67%, 12.69%, and 19.00%, respectively. However, daily supplementation with 2.5 g onion and 2.5 g garlic per 600 g DM feed increased sperm count (×106/nl by 12.82%, whereas daily supplementation with 5 g onion and 5 g garlic per 600 g DM feed reduced it by 10.26% in Koekoek breeder cocks. Dietary onion and garlic supplemental inclusion levels of 3.009, 3.191, 4.621, 6.601, 6.719, 2.327, 2.385, and 2.247 g per 600 g DM feed supported optimum progressive motile cells (%, immotile sperm cells (%, actual dead sperm count (×106/nl, actual live sperm count (×106/nl, live sperm (%, acrosome morphology defects (%, acrosome detachment (%, and acrosome swelling (%, with probability values ranging from 0.003 to 0.783, whereas minimum progressive motile cells (% increase was achieved at an optimum onion and garlic supplementation levels of 3.009 g per 600 g DM feed.

Issues in product quality have produced recalls and caused drug shortages in United States (U.S.) in the past few years. These quality issues were often due to outdated manufacturing technologies and equipment as well as lack of an effective quality management system. To ensure consistent supply of safe, effective and high-quality drug products available to the patients, the U.S. Food and Drug Administration (FDA) supports modernizing pharmaceutical manufacturing for improvements in product quality. Specifically, five new initiatives are proposed here to achieve this goal. They include: (i) advancing regulatory science for pharmaceutical manufacturing; (ii) establishing a public-private institute for pharmaceutical manufacturing innovation; (iii) creating incentives for investment in the technological upgrade of manufacturing processes and facilities; (iv) leveraging external expertise for regulatory quality assessment of emerging technologies; and (v) promoting the international harmonization of approaches for expediting the global adoption of emerging technologies.

Nine heads of dairy cows were used in the study. The dairy cows were in 7-8 months pregnant condition, lactation II and were expected calving soon.The purpose of this study was to determine the effect of feed supplementation to increase the production and quality of milk. The feeding treatment was divided into 3 groups, G1 (control) given the usual feed given by livestock owners, G11 was given GI+500 g UMMB/h/d and G111 was given GI + 500 g MFS/h/d. Variables observed were feed and nutritional consumption, average milk production, milk quality, cumulative milk production, average 4% fat corrected milk (FCM) production, peak milk production. The experimental design used a completely randomized design of direct pattern, continued by Duncan’s new multiple range test (DMRT) if there were a significant difference of variable values between treatments. The results showed that the addition of dietary supplement significantly affected the mean consumption of crude protein between GIII and G1 and G11, respectively 1.22 kg/d versus 0.99 and 0.33 kg/d. The average milk production was also influenced by the addition of dietary supplement that was between G1; G11 and G111, respectively 9.55; 10.69 and 11.85 l/d. Cumulative milk and 4% FCM production were also significantly different at P milk production.

1. This experiment was conducted to evaluate the effects of dietary supplementation of resveratrol on laying performance, egg quality, egg yolk cholesterol and antioxidant enzyme activities of laying hens. 2. A total of 360 Beijing PINK-1 laying hens (60 weeks old) were randomly distributed among five dietary treatments, each of which included 6 replicates of 12 hens. Dietary treatments were basal diet supplemented with 0 (control), 0.5, 1.0, 2.0 and 4.0 g/kg diet resveratrol. The study lasted for 9 weeks including 1 week of adaptation and 8 weeks of the main experimental period. 3. The results indicated that dietary resveratrol significantly improved feed conversion ratios during 5-8 weeks and 1-8 weeks of the trial. Increasing dietary concentrations of the resveratrol linearly improved Haugh unit and albumen height of eggs. 4. The content of total cholesterol (TC), total triglyceride (TG), low density lipoprotein cholesterol (LDL-C), very low density lipoprotein cholesterol (VLDL-C) in serum and cholesterol in yolk was significantly decreased by dietary resveratrol, and there were significant linear correlations between these indexes and resveratrol supplemental levels. 5. Dietary resveratrol supplementation significantly improved serum Glutathione peroxidase (GSH-Px) enzyme activity and decreased serum malondialdehyde (MDA) content in groups with 2.0 and 4.0 g/kg resveratrol as compared to the control, respectively. However, supplementation of resveratrol did not affect the activity of serum superoxide dismutase (SOD). 6. It is concluded that resveratrol supplementation has a positive effect on performance, lipid-related traits and antioxidant activity of laying hens.

Noh, Sang Ha
1997-01-01
Quality evaluation of agricultural products has been interested to many researchers for many years and as the result, several nondestructive techniques and so many papers have been reported for quality evaluation of agricultural products. These nondestructive techniques are based on the detection of mechanical, optical, electrical, electro-magnetical, dielectric and vibrational properties of agricultural products that are well correlated with certain quality factors of the products such as color, shape, firmness, sugar content, external or internal defects, moisture content, etc. The sophistication of nondestructive methods has evolved rapidly with modem technologies. In this paper an emphasis was put on reviewing some of those papers and techniques which could be led to on-line measurement for practical use.

Slavko Mirecki
2017-01-01
Full Text Available Skorup is Montenegrin traditional dairy product. Its main characteristics are extremely high content of milk fat and centuries-old technology. Due to the specific technology, high nutritional value and its historical heritage, Skorup deserves to be labelled as product with protected designation of origin (PDO or protected geographical indication (PGI. The purpose of this study was to collect the most important data about Skorup technology and quality and to launch the process of protection. The chemical quality of raw milk was analysed using IR spectrophotometry, the number of somatic cells and total bacteria count by flow cytometry, and Skorup composition by FTIR spectrophotometry. The presence of Escherichia coli, coagulase positive staphylococci and aerobic mesophilic bacteria in Skorup was detected by standard broth base methods. All Skorup samples contained more than 80 % of fat in dry matter, more than 70 % dry matter, approximately 60 % milk fat and 6 % proteins. The sensory characteristics of all samples were excellent, and according to sensory classification, they belong to the highest classes (I and IA. However, five out of twenty samples did not meet requirements for hygienic quality, which implies the urgent need for improvement of hygiene conditions during its production.

1. Four experimental diets containing 0, 0.5, 1.0 and 2.0% fermented pomegranate by-products (FPB) were supplied to 320d-old broilers to evaluate the effects of FPB on growth performance, nutritional composition, fatty acid profile and oxidative stability of meat. 2. Dietary supplementation of FPB linearly increased the weight gain and feed intake of broilers with linear reduction in feed conversion ratio. 3. The crude protein, iron, magnesium, and sodium content were linearly higher, whereas cholesterol was linearly lower in the breast meat of FPB-supplemented broilers. In thigh meat, linearly lower ether extract and cholesterol with higher moisture was noted in response to increasing levels of FPB. 4. The proportion of saturated fatty acids was both linearly and quadratically lower in breast and thigh meat, whereas those of monounsaturated fatty acids of breast (linear and quadratic) and n-3 fatty acids of breast and thigh (linear) meat was higher in the FPB-supplemented broilers. The n-6/n-3 ratio of breast meat was linearly lower in response to FPB supplementation. The hypocholesterolaemic to hypercholesterolaemic ratio of thigh meat was higher in the FPB-supplemented groups. 5. The thiobarbituric acid reactive substances and pH value were lower in the breast and thigh meat of FPB-supplemented broilers. 6. Thus, additive supplementation of the diet with up to 2% FPB improved the nutritional quality, fatty acid profile and shelf life of broiler meat.

An environmental technology information system was developed by EG ampersand G Idaho, Inc. at the Idaho National Engineering Laboratory (INEL) for the Department of Energy (DOE). The purpose of the system is to reduce costs and time associated with evaluating potential remedial alternatives for a waste site. The information system is organized to aid in the CERCLA process by describing the implementability, effectiveness, and cost of many remedial technologies. Technology categories included in the information system include: Institutional Controls, Retrieval, Separation, Characterization, Physical/Chemical Treatment, Biological Treatment, Thermal Treatment, Storage, Transportation, Disposal, Migration Control (containment), Support Systems, Waste Minimization, and Remote Operations. Two hundred and sixty processes are summarized in these technology areas. Information on these processes was collected from EPA publications, books, journal articles, conference proceedings, vendors, DOE publications, and technical experts. The purpose of this paper is to familiarize readers with issues associated with the development of information systems. A major issue is the system and software quality, which can be controlled by configuration management. Another major issue is the documentation of data quality indicators in references used to collect data for the system, which can not be controlled but must be planned for in the review process

Oral calorie supplements for cystic fibrosis.
Smyth, Rosalind L; Rayner, Oli
2017-05-04
Poor nutrition occurs frequently in people with cystic fibrosis and is associated with other adverse outcomes. Oral calorie supplements are used to increase total daily calorie intake and improve weight gain. However, they are expensive and there are concerns they may reduce the amount of food eaten and not improve overall energy intake. This is an update of a previously published review. To establish whether in people with cystic fibrosis, oral calorie supplements: increase daily calorie intake; and improve overall nutritional intake, nutritional indices, lung function, survival and quality of life. To assess adverse effects associated with using these supplements. We searched the Cochrane Cystic Fibrosis Trials Register comprising references from comprehensive electronic database searches, handsearches of relevant journals and abstract books of conference proceedings. We contacted companies marketing oral calorie supplements.Last search: 18 October 2016. Randomised or quasi-randomised controlled trials comparing use of oral calorie supplements for at least one month to increase calorie intake with no specific intervention or additional nutritional advice in people with cystic fibrosis. We independently selected the included trials, assessed risk of bias and extracted data. We contacted the authors of included trials and obtained additional information for two trials. We identified 21 trials and included three, reporting results from 131 participants lasting between three months and one year. Two trials compared supplements to additional nutritional advice and one to no intervention. Two of the included trials recruited only children. In one trial the risk of bias was low across all domains, in a second trial the risk of bias was largely unclear and in the third mainly low. Blinding of participants was unclear in two of the trials. Also, in one trial the clinical condition of groups appeared to be unevenly balanced at baseline and in another trial there were

Vitamin C is an essential micronutrient and powerful antioxidant. Observational studies have shown an inverse relationship between vitamin C intake and major cardiovascular events and cardiovascular disease (CVD) risk factors. Results from clinical trials are less consistent. To determine the effectiveness of vitamin C supplementation as a single supplement for the primary prevention of CVD. We searched the following electronic databases on 11 May 2016: the Cochrane Central Register of Controlled Trials (CENTRAL) in the Cochrane Library; MEDLINE (Ovid); Embase Classic and Embase (Ovid); Web of Science Core Collection (Thomson Reuters); Database of Abstracts of Reviews of Effects (DARE); Health Technology Assessment Database and Health Economics Evaluations Database in the Cochrane Library. We searched trial registers on 13 April 2016 and reference lists of reviews for further studies. We applied no language restrictions. Randomised controlled trials of vitamin C supplementation as a single nutrient supplement lasting at least three months and involving healthy adults or adults at moderate and high risk of CVD were included. The comparison group was no intervention or placebo. The outcomes of interest were CVD clinical events and CVD risk factors. Two review authors independently selected trials for inclusion, abstracted the data and assessed the risk of bias. We included eight trials with 15,445 participants randomised. The largest trial with 14,641 participants provided data on our primary outcomes. Seven trials reported on CVD risk factors. Three of the eight trials were regarded at high risk of bias for either reporting or attrition bias, most of the 'Risk of bias' domains for the remaining trials were judged as unclear, with the exception of the largest trial where most domains were judged to be at low risk of bias.The composite endpoint, major CVD events was not different between the vitamin C and placebo group (hazard ratio (HR) 0.99, 95% confidence interval

The purpose of this study was to analyze differences between preadolescents and adolescents on the use of technology and to test the contribution of using Internet and mobile phone, and circadian preference on sleep quality. We recruited a sample of 850 (364 males) preadolescents and adolescents. Self-report questionnaires about sleep schedule, sleep wake behavior problems, circadian preferences, and the use of technology (e.g., Internet and mobile phone) were administered. Students were asked to fill out the School Sleep Habits Survey, a self-report questionnaire on the use of technology, the Mobile Phone Involvement Questionnaire (MPIQ), and the Shorter Promis Questionnaire (SPQ). Adolescents reported more sleep problems, a tendency toward eveningness, and an increase of Internet and phone activities, as well as social network activities, while preadolescents were more involved in gaming console and television viewing. The regression analysis performed separately in the two age groups showed that sleep quality was affected by the circadian preference (eveningness) in both groups. Adolescents' bad sleep quality was consistently associated with the mobile phone use and number of devices in the bedroom, while in preadolescents, with Internet use and turning-off time. The evening circadian preference, mobile phone and Internet use, numbers of other activities after 21:00, late turning off time, and number of devices in the bedroom have different negative influence on sleep quality in preadolescents and adolescents. © 2015 American Academy of Sleep Medicine.

Full Text Available Objective This study was conducted to evaluate various wheat supplementation levels on growth performance, blood profiles, nutrient digestibility, and pork quality in growing-finishing pigs. Methods A total of 120 growing pigs ([Yorkshire×Landrace]×Duroc, with an average 27.75± 1.319 kg body weight, were used in growth trial. Pigs were allotted into each treatment by body weight and sex in 4 replicates with 6 pigs per pen in a randomized complete block design. Four-phase feeding programs were used in this experiment. The treatments included the following: i corn-soybean meal (SBM – based diet (CON, ii corn-SBM – based diet+15% of wheat (W15, iii corn-SBM – based diet+30% of wheat (W30, iv corn-SBM – based diet+45% of wheat (W45, and 5 corn-SBM–based diet+60% of wheat (W60. Results There was no significant difference in growth performance among the dietary treatments. However, the gain-to-feed (G:F ratio tended to increase (quadratic, p<0.08 when the pigs were fed a higher wheat diet during the finishing period. The digestibility of crude ash and fat tended to decrease as the wheat supplementation level increased (p<0.08. The proximate analysis of the longissimus muscle was not affected by the dietary level of wheat. The crude ash content in pork was decreased linearly as the wheat supplementation level increased (p = 0.05. There was no significant difference in the pH level, shear force, water holding capacity, and cooking loss of the pork. In pork and fat, L*, a*, and b* values were not significantly different among dietary treatments. Conclusion Wheat can be supplemented up to 60% in a growing-finishing pig without detrimental effects on growth and pork quality. The G:F ratio tended to improve in the finishing period by wheat inclusion.

The aim of this study was to evaluate the effect of the inclusion of red seaweed supplementation to standard poultry diets on production performance, egg quality, intestinal histology, and cecal short-chain fatty acids in Lohmann Brown Classic laying hens. A total of 160 birds were randomly assigned to 8 treatment groups. Control hens were fed a basal layer diet; positive control hens were fed a diet containing 2% inulin; and 6 treatment groups were fed a diet containing one of the following; 0.5, 1, or 2% Chondrus crispus (CC0.5, CC1, and CC2, respectively) and one of the same 3 levels of Sarcodiotheca gaudichaudii (SG0.5, SG1, and SG2, respectively). Dietary supplementation had no significant effect on the feed intake, BW, egg production, fecal moisture content, and blood serum profile of the birds. The feed conversion ratio per gram of egg was significantly more efficient (P = 0.001) for CC2 and SG2 treatments. Moreover, SG1 supplementation increased egg yolk weight (P = 0.0035) and birds with CC1 supplementation had higher egg weight (P = 0.0006).

Five ruminally and abomasally cannulated Nellore heifers (248 ± 9 kg) were used in a 5 × 5 Latin square. Treatments were the control (no supplement) and RDP supplementation to meet 100% of the RDP requirement plus RUP provision to supply 0, 50, 100, or 150% of the RUP requirement. Supplemental RDP (casein plus NPN) was ruminally dosed twice daily, and RUP supply (casein) was continuously infused abomasally. Jugular infusion of [NN]-urea with measurement of enrichment in urine was used to evaluate urea kinetics. The ratio of urinary 3-methylhistidine to creatinine was used to estimate skeletal muscle protein degradation. Forage NDF intake (2.48 kg/d) was not affected ( ≥ 0.37) by supplementation, but supplementation did increase ruminal NDF digestion ( Urea entry rate and gastrointestinal entry rate of urea were increased by supplementation ( urea entry rate and tended ( = 0.07) to linearly increase gastrointestinal entry rate of urea. Urea use for anabolic purposes tended ( = 0.07) to be increased by supplementation, and RUP provision also tended ( = 0.08) to linearly increase the amount of urea used for anabolism. The fraction of recycled urea N incorporated into microbial N was greater ( urea from the renal tubule than did supplemented heifers. Overall, unsupplemented heifers had greater mobilization of AA from myofibrillar protein, which provided N for urea synthesis and subsequent recycling. Supplemental RUP, when RDP was supplied, not only increased N retention but also supported increased urea N recycling and increased ruminal microbial protein synthesis.

Full Text Available Reduced supplementation frequency is a broadly applied management practice. Ruminants consuming low quality forages/pastures, supplemented less than once daily are able to maintain body weight gain (BWG, efficiency of use of dry matter, nitrogen and other nutrients, as compared with animals supplemented once daily. We evaluated the feeding behavior, dry matter intake (DMI, dry matter and organic matter digestibility (DMD and OMD, BWG, Longissimus muscle area and backfat depth of Nellore steers raised on Brachiaria brizantha cv. Marandu pastures during the dry season, with different supplementation patterns. Thirty six animals (338 ± 40.7 kg were distributed over nine paddocks according to a completely randomized design. Treatments were based on supplementation frequency: once daily (OD, once daily except Saturdays and Sundays (SS, or on alternate days (AD, at 1.0 %, 1.4 % and 2.0 % BW, respectively. Average total DMI accounted for 1.6 % BW day-1, with no effect of supplementation frequency. Supplementation frequency had no effect on BWG or grazing time during the day. There was no difference in Longissimus muscle area animals supplemented daily, SS and AD. The backfat depth was thinner in animals supplemented AD, but even in this case, it was within the standards considered satisfactory for a finishing steer. Reducing supplementation frequency seems a good option to lower labor costs without affecting feed efficiency or carcass quality in beef cattle grazing tropical pastures.

[Technological innovations in radiation oncology require specific quality controls].
Lenaerts, E; Mathot, M
2014-01-01
During the last decade, the field of radiotherapy has benefited from major technological innovations and continuously improving treatment efficacy, comfort and safety of patients. This mainly concerns the imaging techniques that allow 4D CT scan recording the respiratory phases, on-board imaging on linear accelerators that ensure perfect positioning of the patient for treatment and irradiation techniques that reduce very significantly the duration of treatment sessions without compromising quality of the treatment plan, including IMRT (Intensity Modulated Radiation Therapy) and VMAT (Volumetric Modulated Arc therapy). In this context of rapid technological change, it is the responsibility of medical physicists to regularly and precisely monitor the perfect functioning of new techniques to ensure patient safety. This requires the use of specific quality control equipment best suited to these new techniques. We will briefly describe the measurement system Delta4 used to control individualized treatment plan for each patient treated with VMAT technology.

Despite existing evidence about the benefits of nutrition, physical activity (PA) and sport to the overall health and wellbeing of children, knowledge gaps remain on this relationship in children living with chronic conditions like HIV/AIDS. Such knowledge should inform context specific programs that could enhance the quality of life of children. The purpose of this study was to examine the effects of integrating a nutrition intervention (culturally tailored food supplement) into antiretroviral therapy (ART) on psychosocial outcomes and physical activity among HIV-positive children in Botswana. 201 HIV-positive children (6-15 years; M = 9.44, SD = 2.40) were recruited and randomly assigned (stratified by age and gender) to two groups. The intervention group (n = 97) received a high protein (bean-sorghum plus micronutrients) food supplement, while the control group (n = 104) received a sorghum plus micronutrients supplement. Participants were followed over 12 months. Anthropometric measures, PA, motor performance, and health related quality of life (HRQL) were collected at baseline, 6 and 12 months. Mixed repeated-measures ANOVA revealed a significant time effect of the food supplement on target variables except body fat percentage, speed, and school functioning. Time × treatment interaction was found for physical functioning, psychosocial functioning and total quality of life score. Scores on physical functioning and total of quality life in the intervention group significantly increased from baseline to 6 months compared with the control group ( p = 0.015). A combination of ART and nutritional intervention had a positive effect on physical functioning and total quality of life of HIV-positive children in this study. There were also improvements to physical activity and motor performance tests over time. More research is needed on long term effects of nutrition and PA interventions on HRQL in children living with HIV.

Full Text Available This study evaluated the effects that gradual ractopamine supplementation in diets with nutritional adjustments on pig meat. Were used 80 finishing crossbred barrows in a randomized block design with a 2×5 factorial arrangement (two diets: with and without nutritional adjustment; five levels of ractopamine supplementation: 5-5, 10-10, 20-20, 5-10 and 10-20 ppm in the 14 initial and 14 final study days, four replicates with two animals by experimental unit. Higher shear force values (P<0.05 were obtained using the 5-5 and 10-20 ppm ractopamine supplementation plans in the diets without nutritional adjustment. With nutritionally adjusted diets, the 5-10 ppm of ractopamine supplementation plan yielded higher shear force values (P<0.05. Water retention capacity was higher (P<0.05 for animals fed adjusted diets and 5-5 and 10-20 ppm of actopamine plans. In the 10-20 ppm of ractopamine supplementation plan, meat pH was higher (P<0.05 for diets without nutritional adjustment, whereas in the 20-20 ppm of supplementation plan, pH was higher for adjusted diets.

Full Text Available After decades-old efforts to nudge consumers towards healthier lifestyles through dietary guidelines, diet-related diseases are on the rise. In addition, a growing share of U.S. consumers proactively chooses nutritional supplements as an alternative preventative way of maintaining good health, a $25.5 billion industry in the United States. This paper investigates possible linkages between the economics of consumer supplement choices and the relationship to important dietary and health outcomes. We use National Health and Nutrition Examination Survey (NHANES data to estimate the impact of nutritional supplements intake on respondent's body weight outcomes, controlling for diet quality.: The focus of this article is to determine whether nutritional supplements takers differ from non-takers with regard to their health outcomes when controlling for differences in diet quality, based on individual Healthy Eating Index (HEI-2010 score. The analysis applies treatment effects estimators that account for the selection bias and endogeneity of self-reported behavior and diet-health outcomes. The analysis demonstrates a negative association between supplement intake and BMI but no significant effect on an individual's diet quality. Our findings suggest that individuals proactively invest into their health by taking nutritional supplements instead of improving diet quality through more nutritious food choices. Our results provide important contributions to the literature on a key food policy issue. Knowledge of the determinants of supplement demand in the context of strong diet-health trends should also be helpful to stakeholders in the U.S. produce sector in their competition over consumer market share.

Both chromium (Cr) and probiotic bacillus own the virtues of regulating animal metabolism and meat quality. Purpose of this study was to evaluate the efficiency of supplemental Cr and bacillus in the form of chromium-enriched Bacillus subtilis KT260179 (CEBS) on chicken growth performance, plasma lipid parameters, tissue chromium levels, cecal bacterial composition and breast meat quality. Six hundred of 1-day-old Chinese Huainan Partridge chickens were divided into four groups randomly: Control, inorganic Cr, Bacillus subtilis, and CEBS. The feed duration was 56 days. After 28 days of treatment, broiler feed CEBS or normal B. subtilis had higher body weights than control broiler, and after 56 days, chickens given either CEBS or B. subtilis had greater body weights than control broiler or those given inorganic Cr. Plasma total cholesterol, triglycerides, and low density lipoprotein cholesterol levels declined significantly in the CEBS group compared with the control, whereas plasma high density lipoprotein cholesterol levels increased significantly. The concentration of Cr in blood and breast muscle increased after CEBS and inorganic Cr supplementation. B. subtilis and CEBS supplementation caused a significant increase in the numbers of Lactobacillus and Bifidobacterium in the caecum, while the numbers of Escherichia coli and Salmonella decreased significantly compared to the control. Feed adding CEBS increased the lightness, redness, and yellowness of breast meat, improved the water-holding capacity, decreased the shear force and cooking loss. In all, CEBS supplementation promoted body growth, improved plasma lipid parameters, increased tissue Cr concentrations, altered cecal bacterial composition and improved breast meat quality.

Full Text Available This paper examines the rate and determinants of adoption of improved rice quality enhancing technologies among a randomly selected sample of 150 farmers and 18 rice processors from six rice producing areas of Niger State. Data were collected through interview schedule using questionnaires. Descriptive statistics and regression model were adopted to analyze data. Results show that adoption of quality enhancing technologies was low among the selected sample of these rice value chain actors. The adoption indices of on-farm and post-harvest quality enhancing practices were 0.46 and 0.37 respectively. Some socioeconomic attributes including: Age, level of education, contact with extension, access to credit and level of commercialization were statistically significant determining factors (P≤0.05 influencing adoption at farm level, while post-harvest technology adoption was determined by level of education, access to credit and membership of cooperatives. Promotion of quality enhanced technologies among these actors in the rice value chain is recommended.

In consideration of the increasing popularity of frankincense and the widely published quality problems associated with botanical dietary supplements, a survey was conducted for the first time on the quality of frankincense containing botanical dietary supplements. Six US products representing 78 % of the units sold and 70 % of the market value, and 11 European products representing 30 % of the units sold and 40 % of the market value were tested for their boswellic acid composition profile, label compliance, and claimed health benefits. Special focus was also set on the statements made with regard to the frankincense applied.Only five products out of seventeen disclosed all relevant information for the Boswellia extract, mentioning the species, the part of plant used, and the boswellic acid content. Whereas all products but one claimed to use Boswellia serrata, three products did not mention the resin as the part applied and 10 products did not declare the boswellic acid content. Apart from the different boswellic acid composition determined with a sensitive LC/MS method, 41 % of the products did not comply with the label declaration. Hence, one product from Italy did not contain any of the six characteristic boswellic acids (KBA, AKBA, αBA, βBA, AαBA, AβBA) at all and another US product contained only traces, suggesting the absence of frankincense or the use of Boswellia frereana instead of B. serrata. In another product, the ratios of the individual boswellic acids were different from B. serrata gum resin, indicating the use of another species such as Boswellia sacra or Boswellia carterii. Furthermore, two products revealed different boswellic acid contents from those declared on the label. Further, two products did not declare the use of manipulated Boswellia gum resin extract being enriched in acetyl-11-keto-boswellic acid content reaching up to 66 %. In addition, consumers could be misled by outdated literature or references to in vitro studies

Nazareth, Samantha; Lebwohl, Benjamin; Tennyson, Christina A; Simpson, Suzanne; Greenlee, Heather; Green, Peter H
2015-08-01
There has been increasing interest in the use of complementary and alternative medicine (CAM) in the general population. Little is known about CAM use in patients with celiac disease (CD). We aimed to determine the demographics and clinical characteristics of patients with biopsy-proven CD who use dietary supplements to treat their symptoms. CD patients completed a questionnaire on demographics, types of dietary supplement use, attitudes toward CAM, and 3 validated scales: CD-related Quality Of Life (CD-QOL), the CD Symptoms Index (CSI), and the CD Adherence Test (CDAT). Of 423 patients, 100 (23.6%) used dietary supplements to treat CD symptoms. The most frequently used supplement was probiotics (n=59). Supplement users had a higher CD-QOL score (75.06 vs. 71.43, P=0.04) but had more symptoms based on CSI (35.64 vs. 32.05, P=0.0032). On multivariable analysis, adjusting for age, sex, education, symptom improvement following a gluten-free diet, and where the survey was completed, patients presenting with classic symptoms (OR, 2.56; 95% CI, 1.01-6.44) or nonclassic symptoms (OR, 2.75; 95% CI, 1.04-7.24) were significantly more likely to use supplements than those with asymptomatic/screen-detected CD. Patients with biopsy-proven CD who have symptoms at diagnosis tend to use dietary supplements more than those that are screen detected. Those using supplements report persistent symptoms, but a higher quality of life. The contribution of the gluten-free diet and supplement use to quality of life in the symptomatic CD patient needs to be determined.

The present study was designed to test the modulatory effect of dietary quercetin on follicle population, apoptosis, in vitro maturation rate and quality of oocytes in heat stressed female rabbits. A total of thirty-four New Zealand White heat stress (HS) exposed female rabbits were either fed with quercetin supplemented diet (QU-HS) or non-supplemented (HS) diet. Firstly, laparotomy was performed for oocyte retrieval and then, oocyte grading and COCs dimensional assessments were conducted. The A and B-grade oocytes were submitted for in vitro maturation. Thereafter, the ovaries were collected from rabbits and were processed for follicular population estimation and granulosa cells apoptosis. The results showed that follicle number, retrieved oocytes and A-grade oocytes were higher in QU-HS, comparatively. A significant difference was observed in A-grade oocytes dimensions between QU-HS and HS treatment groups. The oocyte maturation rate was same across the groups. The quercetin supplementation significantly improved primordial and antral stage follicles. A greater number of apoptotic cells were observed in primary and antral follicles in the HS group. In conclusion, the quercetin provision improves the follicular development, minimize granulosa cells apoptosis, and maintain the oocyte competence in HS rabbits. Copyright © 2017.

Marine fish as source of protein supplement in meat.
Rasekh, J G
1987-01-01
For the past 2 decades, a great deal of research has been done in fish technology, particularly in the area of mechanically deboned minced fish. Minced fish is the edible muscle flesh of fish that has been mechanically separated from the bones and skin. Ideally, the product is prepared from a high quality fish and resembles hamburger meat. In its final form, minced fish is used either as an ingredient or as an extender in seafood or in food products that require further processing. On the basis of technological advancements, the National Marine Fisheries Service of the U.S. Department of Commerce and the National Fisheries Institute jointly petitioned the U.S. Department of Agriculture in 1980 to add minced fish at a level of 15% in the meat formulation of frankfurters. This paper explores certain aspects of processing, production, acceptance, and hazard assessment of minced fish ingredients as possible protein supplements in meat and poultry food products relative to this request.

A total of 125 Hy-Line Brown hens (38 weeks old were placed at individual cages and assigned to five dietary treatments. The dietary treatments were supplemented with 0, 1.5, 3.0, 4.5 and 6.0% purslane meal. Laying hens were fed for five weeks following a seven day adaptation period. Water and feed were provided ad libitum. Feed intake (FI measured weekly and feed consumption ratio (FCR was calculated at the end of the trial. A total of 25 egg yolk samples of day 35 (n = 5 egg yolks for each treatment were collected to analyse physical quality of eggs. The data were analyzed using Analysis of Variance (ANOVA. Differences between treatment means were further analyzed using Duncan's New Multiple Range Test (DMRT. Results showed that the incorporation of plants rich in ALA did not modify FI, FCR, and egg production. Supplementation of purslane meal in the diets had no effect on physical quality of eggs, including egg weight, yolk weight, albumen index, yolk index and Haugh Unit (HU. The average of egg weight and yolk weight were 60,5 and 15.3 g, respectively. Diet containing purslane meal increased yolk colour. In conclusion, laying hens that fed diet supplemented with purslane meal rich in ALA improved yolk colour and did not change the production performance of the laying hens or the qualities of the eggs.

This study evaluates the effect of vitamin E supplementation source (micellized natural vs. the synthetic form) and dosage (40, 80, or 120 mg/kg) on α-tocopherol concentration in plasma and muscle, antioxidant capacity, and breast meat quality in turkeys. Three hundred female turkeys were randomly selected at an average live weight 63.2 g±0.5 and distributed into 7 groups. One group (control) was fed a standard diet without vitamin E supplementation and the other 6 were given mixed diets supplemented with the natural (d-α-tocopherol) or synthetic (dl-α-tocopheryl acetate) form of vitamin E in 3 dosages (40, 80, or 120 mg/kg). Following 11 wk feeding, results showed that performance parameters were not modified either by source or dosage of vitamin E supplementation to the turkeys. Plasma and muscle α-tocopherol at d 9 of refrigerated storage were higher when turkeys were supplemented with the natural form at higher doses. Losses in the concentration of α-tocopherol in meat between the beginning and the end of the 9 d refrigerated storage were greater in the groups supplemented with the synthetic form of vitamin E compared to those receiving the natural supplementation. The relationship between plasma α-tocopherol and the Trolox equivalent antioxidant capacity followed a different trend depending on the vitamin E source. Intramuscular fat was not significantly affected by the vitamin E source supplementation; however the slope of the linear regression equation was lower for the natural form than for the synthetic form. Turkeys given the natural form had higher C18:1n-9 but lower C15:1, C17:1, C20:5n-3, and C22:6n-3 in breast muscle. Meat samples from turkeys supplemented with natural vitamin E had higher deoxymyoglobin at d 3, 6, and 9 and lower metmyoglobin at d 9 of refrigerated storage than those receiving the synthetic form. Dietary supplementation with medium doses (80 mg/kg) micellized d-α-tocopherol is an interesting feeding strategy for

Full Text Available Objective This study was conducted to investigate the effect of dietary onion (Allium cepa extract (OE supplementation on growth performance, apparent total tract retention (ATTR, blood profile, carcass characteristics and meat quality in broilers. Methods Four hundred male broiler chicks (Ross 308, 3-d old were randomly allocated to four dietary treatments for 28 d feeding trial. Each treatment has five replications with 20 birds each. Four dietary treatments were designated according to the OE supplementation levels (0 as control, 5, 7.5, and 10 g of OE per kg of basal diet respectively. On d 28, a total of 20 birds from each treatment were subjected for ATTR, serum biochemical assay, carcass characteristic and organ weight measurement. Results Overall weight gain of OE 7.5 g/kg group was higher (p = 0.04 than control group. The ATTRs of dietary energy (p<0.01 and ether extract (p = 0.04 linearly increased with increasing levels of dietary OE. However, no difference in ATTR of dry matter and crude protein was evident. Furthermore, serum IgG concentration increased linearly (p<0.01 and quadratically (p = 0.03 with increasing OE supplementation. No differences in carcass dressing weight and amount of abdominal fat by treatments were observed. Also, the weight of organ including immune organ was not different among the treatments. The TBARS values of 10 d stored breast meat decreased linearly (p<0.01 and quadratically (p<0.01 with increasing dietary OE levels. The meat color was also affected, with lower (p<0.01 redness score in meats from OE supplemented groups. This study showed that dietary OE improved broiler weight gain presumably by increasing feed intake and ATTR of both energy and ether extract. The dietary OE increased serum IgG level and meat anti-oxidation capacity. Conclusion This study implies that the recommended level of dietary OE supplementation could be beneficial for improving broiler performance and meat quality.

Davaa, S.; Khuukhenkhuu, G.
2007-01-01
The Nuclear Research Centre (NRC) at the National University of Mongolia, founded in 1965, is the only educational and research institution in Mongolia that carries out fundamental and applied low energy nuclear physics research. The main activities of the NRC are described in the Mission, Strategic Goals, and Objectives Statement of the NRC (http://www.num.edu.mn/nrc). The mission of the Nuclear Research Center is to be the leading national institution that conducts both training and research/development to obtain new information and results, to develop new methodology and technology in fundamental and applied nuclear physics, and also to develop equipment and devices. In order to implement quality management in nuclear technology training activities and conduct quality assurance, the Bachelor's education program has been required to create a self evaluation and the first copy of the report had been produced. It is a common perception that the main mechanism of higher education quality assurance is the internal quality management, and quality external monitoring. Therefore a general model used in most countries for higher education quality assurance. This model's main device is internal and external evaluation. The external evaluation has responsibility to improve accreditation, responsibility/commitment. Based on its self evaluation, the organization will develop its quality plan and, combined with external evaluation conclusions, will be lead toward quality improvement. The most important part of quality assessment is the use of external experts' assessment. Our nuclear research center is the only educational and research institution in the country, and, thus, it is impossible to find respectable independent experts (who do not get involved in our operations). In order to hire reputable foreign expert there are several obstacles: It is not easy to find a person who would know not only nuclear technology training but also do the benchmarking based on our

2011-03-01
To investigate the relationship between the use of health information technology (HIT) and physician perceptions of providing high-quality care and to determine whether this relationship has changed over time. We used 2 waves of longitudinal data from the Community Tracking Study Physician Surveys, 2000-2001 and 2004-2005. Three measures of HIT were examined: a binary variable measuring the use of at least 1 type of HIT, a continuous variable measuring the total number of HIT types, and a binary variable measuring use of all 5 HIT types related to "meaningful use" of HIT as defined by Centers for Medicare and Medicaid Services. Three multivariate models were estimated to study the effect of each HIT measure on physicians' perception of providing high-quality care. Individual fixed-effects estimation also was used to control for individual time-invariant factors. Using at least 1 type of HIT significantly enhanced physicians' perception of providing high-quality care in 2000-2001, but not in 2004-2005. The marginal effect of adding 1 extra HIT type was positive and statistically significant in both periods. The association between using all 5 HIT types related to meaningful use and perceived quality was statistically significant in 2000-2001, but not in 2004-2005. Health information technology has become a multifunctional system and appears to have enhanced physicians' perception of providing high-quality care. Physicians' perceptions of medical care quality improved as the number of HIT types used increased. This study supports more extensive use of HIT in physician practices.

Full Text Available DNA-based testing has been gaining acceptance as a tool for authentication of a wide range of food products; however, its applicability for testing of herbal supplements remains contentious.We utilized Sanger and Next-Generation Sequencing (NGS for taxonomic authentication of fifteen herbal supplements representing three different producers from five medicinal plants: Echinacea purpurea, Valeriana officinalis, Ginkgo biloba, Hypericum perforatum and Trigonella foenum-graecum. Experimental design included three modifications of DNA extraction, two lysate dilutions, Internal Amplification Control, and multiple negative controls to exclude background contamination. Ginkgo supplements were also analyzed using HPLC-MS for the presence of active medicinal components.All supplements yielded DNA from multiple species, rendering Sanger sequencing results for rbcL and ITS2 regions either uninterpretable or non-reproducible between the experimental replicates. Overall, DNA from the manufacturer-listed medicinal plants was successfully detected in seven out of eight dry herb form supplements; however, low or poor DNA recovery due to degradation was observed in most plant extracts (none detected by Sanger; three out of seven-by NGS. NGS also revealed a diverse community of fungi, known to be associated with live plant material and/or the fermentation process used in the production of plant extracts. HPLC-MS testing demonstrated that Ginkgo supplements with degraded DNA contained ten key medicinal components.Quality control of herbal supplements should utilize a synergetic approach targeting both DNA and bioactive components, especially for standardized extracts with degraded DNA.

We conducted two studies to test the validity, reliability, feasibility and acceptability of using video chat technology to quantify dietary and pill-taking (i.e. supplement and medication) adherence. In study 1, we investigated whether video chat technology can accurately quantify adherence to dietary and pill-taking interventions. Mock study participants ate food items and swallowed pills, while performing randomised scripted 'cheating' behaviours to mimic non-adherence. Monitoring was conducted in a cross-over design, with two monitors watching in-person and two watching remotely by Skype on a smartphone. For study 2, a twenty-two-item online survey was sent to a listserv with more than 20 000 unique email addresses of past and present study participants to assess the feasibility and acceptability of the technology. For the dietary adherence tests, monitors detected 86 % of non-adherent events (sensitivity) in-person v. 78 % of events via video chat monitoring (P=0·12), with comparable inter-rater agreement (0·88 v. 0·85; P=0·62). However, for pill-taking, non-adherence trended towards being more easily detected in-person than by video chat (77 v. 60 %; P=0·08), with non-significantly higher inter-rater agreement (0·85 v. 0·69; P=0·21). Survey results from study 2 (n 1076 respondents; ≥5 % response rate) indicated that 86·4 % of study participants had video chatting hardware, 73·3 % were comfortable using the technology and 79·8 % were willing to use it for clinical research. Given the capability of video chat technology to reduce participant burden and outperform other adherence monitoring methods such as dietary self-report and pill counts, video chatting is a novel and promising platform to quantify dietary and pill-taking adherence.

The market of pharmaceutical products is offering a wide range of supplements. Most of the consumers believe that these products will improve their state of health, but are they getting what they want and what they are paying for? The aim of the study was to evaluate the quality of selected dietary supplements containing conjugated linoleic acid (CLA). All supplements were available in the Warsaw markets and bought from pharmacies. Assessment of the quality of food supplements was achieved by analysis of fatty acid using gas chromatography coupled with a mass spectrometer. On the basis of the investigations carried out, it was found that content of CLA in selected dietary supplements ranged between 282 and 528 mg by weight of a single capsule. The content of bioactive ingredients found in three of the four product supplements assessed was lower than was claimed by the manufacturer.

2017-01-01
PURPOSE OF REVIEW: This review provides an appraisal of recent evidence for or against selenium supplementation in patients with autoimmune thyroid diseases, and discusses possible effect mechanisms. RECENT FINDINGS: Epidemiological data suggest an increased prevalence of autoimmune thyroid...... diseases under conditions of low dietary selenium intake. Two systematic reviews have evaluated controlled trials among patients with autoimmune thyroiditis and report that selenium supplementation decreases circulating thyroid autoantibodies. The immunomodulatory effects of selenium might involve reducing...... proinflammatory cytokine release. However, clinically relevant effects of selenium supplementation, including improvement in quality of life, are more elusive. In Graves’ disease, some, but not all, trials indicate that adjuvant selenium supplementation enhances the restoration of biochemical euthyroidism...

Health Information Technology in Healthcare Quality and Patient Safety: Literature Review.
Feldman, Sue S; Buchalter, Scott; Hayes, Leslie W
2018-06-04
The area of healthcare quality and patient safety is starting to use health information technology to prevent reportable events, identify them before they become issues, and act on events that are thought to be unavoidable. As healthcare organizations begin to explore the use of health information technology in this realm, it is often unclear where fiscal and human efforts should be focused. The purpose of this study was to provide a foundation for understanding where to focus health information technology fiscal and human resources as well as expectations for the use of health information technology in healthcare quality and patient safety. A literature review was conducted to identify peer-reviewed publications reporting on the actual use of health information technology in healthcare quality and patient safety. Inductive thematic analysis with open coding was used to categorize a total of 41 studies. Three pre-set categories were used: prevention, identification, and action. Three additional categories were formed through coding: challenges, outcomes, and location. This study identifies five main categories across seven study settings. A majority of the studies used health IT for identification and prevention of healthcare quality and patient safety issues. In this realm, alerts, clinical decision support, and customized health IT solutions were most often implemented. Implementation, interface design, and culture were most often noted as challenges. This study provides valuable information as organizations determine where they stand to get the most "bang for their buck" relative to health IT for quality and patient safety. Knowing what implementations are being effectivity used by other organizations helps with fiscal and human resource planning as well as managing expectations relative to cost, scope, and outcomes. The findings from this scan of the literature suggest that having organizational champion leaders that can shepherd implementation, impact culture

1. This study was conducted to determine the effects of enzyme supplementation of maize/wheat-based diets on the performance, egg quality, and serum and bone parameters of laying hens. 2. During the 12-week experimental period, a total of 72 laying hens aged 52 weeks were randomly distributed among 6 experimental groups. Each experimental group contained 4 replicates, each with three birds. The experiment was a randomised design consisting of a 3 × 2 factorial arrangement, with three levels of wheat substitution and two levels of enzyme (xylanase: 1500.00 U/kg, β-glucanase: 100 000 U/kg, cellulase: 1 000 000 U/kg, α-amylase: 160 000 U/kg) inclusion in the diet. Wheat replaced 0, 50, or 100% of maize with or without 1.0 g/kg enzyme supplementation in iso-nitrogenous and iso-caloric experimental diets. 3. Body weight, egg production, egg weight, egg mass, eggshell thickness, and the feed conversion ratio were adversely affected by the wheat-based diet. The eggshell quality parameters decreased with enzyme supplementation to the diet. 4. Wheat-based diets adversely affected calcium and phosphorus concentrations in the tibia, but the addition of the enzymes to the wheat-based diet prevented the negative effects of wheat-based diets on tibia mineralisation in laying hens. The wheat-based diets tended to reduce plasma mineral contents, and the addition of enzymes tended to affect plasma minerals and biomechanical properties of the tibia positively in laying hens. 5. These results indicate that wheat-based diets in aged laying hens adversely affected the mineral metabolism compared with maize-based diets, and the negative effects of wheat on bone mineralisation can be prevented by enzyme supplementation to the diets in laying hens.

The Medical Services Advisory Committee (MSAC) makes recommendations to the Australian Government for funding health technologies under the Medicare Benefits Schedule (MBS). Differences in public, clinical, commercial, and political opinions on health expenditure emphasize the importance of defensible funding decisions. We aimed to evaluate the quality of health technology assessment (HTA) reports over time and among health technologies assessed for MSAC. A cohort study was performed of HTA reports prepared for MSAC between 1998 and 2013. We measured the quality of HTA reports using reporting guidelines proposed by the European Collaboration for Assessment of Health Interventions. Individual component scores across eleven domains were calculated, and summed for an overall aggregate score. We used linear regression to investigate any change in quality over time and among the types of technologies assessed. We included 110 HTA reports. The safety (80 percent), effectiveness (84 percent), economic (74 percent), and organizational (99 percent) domains were better reported than the psychological, social, and ethical considerations (34 percent). The basic (75 percent), methodological (62 percent), background (82 percent), contextual (46 percent), status quo (54 percent), and technical information (66 percent) that framed each assessment were inconsistently reported. On average, overall quality scores increased by 2 percent (p technologies (p = 0.22). HTA reports prepared for MSAC are a key tool in allocating scarce health resources. The overall quality of these reports has improved, but the reporting of specific domains and subthemes therein could be better addressed.

'Omics technologies are gaining importance to support regulatory toxicity studies. Prerequisites for performing 'omics studies considering GLP principles were discussed at the European Centre for Ecotoxicology and Toxicology of Chemicals (ECETOC) Workshop Applying 'omics technologies in Chemical Risk Assessment. A GLP environment comprises a standard operating procedure system, proper pre-planning and documentation, and inspections of independent quality assurance staff. To prevent uncontrolled data changes, the raw data obtained in the respective 'omics data recording systems have to be specifically defined. Further requirements include transparent and reproducible data processing steps, and safe data storage and archiving procedures. The software for data recording and processing should be validated, and data changes should be traceable or disabled. GLP-compliant quality assurance of 'omics technologies appears feasible for many GLP requirements. However, challenges include (i) defining, storing, and archiving the raw data; (ii) transparent descriptions of data processing steps; (iii) software validation; and (iv) ensuring complete reproducibility of final results with respect to raw data. Nevertheless, 'omics studies can be supported by quality measures (e.g., GLP principles) to ensure quality control, reproducibility and traceability of experiments. This enables regulators to use 'omics data in a fit-for-purpose context, which enhances their applicability for risk assessment. Copyright © 2017 Elsevier Inc. All rights reserved.

Should states and local governments regulate dietary supplements?
Starr, Ranjani
2016-01-01
Federal regulation of dietary supplements in the United States is governed by the Dietary Supplement Health and Education Act of 1994. The law has been criticized as weak and ineffective. Alarming research has emerged demonstrating that supplements may be mislabelled, contaminated, adulterated with dangerous or unknown compounds, or sold at toxic doses. As a result, the health community has raised concerns about the safety and quality of dietary supplements. Increased federal oversight is an important avenue for improving supplement safety; however, states and local governments may also pursue strategies to strengthen the overall regulatory control of dietary supplements. States and local governments have substantial experience in regulating other products that pose a risk to public health, such as tobacco. Additionally, much has been learned about the tactics the tobacco industry has employed to protect its interests. Lessons learned may be applied to new regulatory efforts aimed at improving the safety of dietary supplements at the state and local levels. Copyright © 2015 John Wiley & Sons, Ltd.

As information and communication technology applied to telecare has become a trend in elder care services, evaluation of the program is vital for further program design and development. This study evaluated the variables influencing the use of a telecare service program by the elderly. A questionnaire survey was used to explore the relationship between quality of life and technology acceptance of a telecare program in Taiwan. In addition, open-ended questions were used to elicit qualitative information regarding the experience of technology use. The results revealed that elderly persons with better social welfare status and health condition, who used the device frequently, had higher quality of life and accepted technology use. The correlation results also indicated that elderly persons who perceived telecare as useful in solving health problems, had the intention to use the program, and were willing to continue use, also had a better perception toward quality of life regarding their interpersonal relationships and living environment. Nonetheless, cost may be an issue that will impede their willingness to use the technology in care service.

Tyrosine supplementation for phenylketonuria.
Webster, Diana; Wildgoose, Joanne
2013-06-05
Phenylketonuria is an inherited disease for which the main treatment is the dietary restriction of the amino acid phenylalanine. The diet has to be initiated in the neonatal period to prevent or reduce mental handicap. However, the diet is very restrictive and unpalatable and can be difficult to follow. A deficiency of the amino acid tyrosine has been suggested as a cause of some of the neuropsychological problems exhibited in phenylketonuria. Therefore, this review aims to assess the efficacy of tyrosine supplementation for phenylketonuria. To assess the effects of tyrosine supplementation alongside or instead of a phenylalanine-restricted diet for people with phenylketonuria, who commenced on diet at diagnosis and either continued on the diet or relaxed the diet later in life. To assess the evidence that tyrosine supplementation alongside, or instead of a phenylalanine-restricted diet improves intelligence, neuropsychological performance, growth and nutritional status, mortality rate and quality of life. We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group's Trials Register which is comprised of references identified from comprehensive electronic database searches, handsearches of relevant journals and abstract books of conference proceedings. Additional studies were identified from handsearches of the Journal of Inherited Metabolic Disease (from inception in 1978 to 1998). The manufacturers of prescribable dietary products used in the treatment of phenylketonuria were also contacted for further references.Date of the most recent search of the Group's Inborn Errors of Metabolism Trials Register: 28 June 2012. All randomised or quasi-randomised trials investigating the use of tyrosine supplementation versus placebo in people with phenylketonuria in addition to, or instead of, a phenylalanine-restricted diet. People treated for maternal phenylketonuria were excluded. Two authors independently assessed the trial eligibility, methodological quality

To investigate the effects of oral zinc supplementation on fatigue intensity and quality of life of patients during chemotherapy for colorectal cancer. A prospective, randomized, double-blinded, placebo-controlled study was conducted with 24 patients on chemotherapy for colorectal adenocarcinoma in a tertiary care public hospital. The study patients received zinc capsules 35mg (Zinc Group, n=10) or placebo (Placebo Group, n=14) orally, twice daily (70mg/day), for 16 weeks, from the immediate postoperative period to the fourth chemotherapy cycle. Approximately 45 days after surgical resection of the tumor, all patients received a chemotherapeutic regimen. Before each of the four cycles of chemotherapy, the Functional Assessment of Chronic Illness Therapy-Fatigue scale was completed. We used a linear mixed model for longitudinal data for statistical analysis. The scores of quality of life and fatigue questionnaires were similar between the groups during the chemotherapy cycles. The Placebo Group presented worsening of quality of life and increased fatigue between the first and fourth cycles of chemotherapy, but there were no changes in the scores of quality of life or fatigue in the Zinc Group. Zinc supplementation prevented fatigue and maintained quality of life of patients with colorectal cancer on chemotherapy.

1994-01-01
Traditional fish processing technologies are important in the preservation and utilization of fish in many developing countries. These technologies as well as the quality of the products arc poorly defined and understood. This study therefore investigated the production, quality characteristics and utilization of traditional cured fish products using field surveys and laboratory techniques. It was found that simple traditional technologies for smoking, salting and drying are used to process fish in Ghana; infrastructural requirements for traditional fish processing have high local material input. The cured fish products have distinct sensory, physico-chemical properties and variable storage characteristics. Processors' perceptions of important quality attributes of cured fish products were linked to storage, marketing and other product delivery characteristics. Consumers' perceptions and expectations of desirable quality attributes however were found to he dependent upon the type of cured fish product and the food in which it is used. Cost was found to be the most important factor influencing the utilization of animal protein foods; other factors were nutritional quality, beliefs and food habits. Animal protein consumers showed a high preference for fish in general and cured fish products in particular. U sing central composite rotatable design for k = 3, representing salting time (0 - 24), drying temperature (40°C - 60°C) and drying time (6 - 20 hours), equations for predicting objective and subjective quality indices were developed. The critical salting time for attaining minimum moisture content were 20.5, 12 and 8.5 hours respectively for products dried at 40°C, 50°C and 60°C. At each salting time, the mean hardness score was dependent on the drying temperature and drying time whilst the mean colour and overall acceptability scores were influenced by drying temperature. It was found that the long salting time (24-72 hours) and drying time (5

The composition of bioactive components in dairy products depends on their content in raw milk and the processing conditions. The experimental material consisted of the milk of dairy goats supplemented with 120 g d(-1) per head of false flax cake. The aim of the study was to evaluate the quality of kefir produced from goat's milk with a higher content of bioactive components resulting from supplementation of the goats' diet with false flax cake. The administration of false flax cake to goats had a positive effect on the fatty acid profile of the raw milk, causing an increase in the proportion of polyunsaturated fatty acids (PUFA), including conjugated linoleic acid (CLA) and n-3 fatty acids. Their increased percentage was detected in the kefir after production as well as after storage. The processing value of the harvested milk did not differ from the qualitative characteristics of milk from goats of the control group. Increasing the proportion of bioactive components in goat's milk did not result in changes in the acidity, texture, colour, flavour, aroma or consistency of the kefir obtained. Milk and kefir obtained after the administration of false flax cake to goats contain bioactive components (PUFA including CLA, n-3 and monoenic trans fatty acids) in significant amounts. Kefir from experimental goat's milk did not differ in quality from kefir made from the milk of the control group. © 2014 Society of Chemical Industry.

Supplementation with compounds rich in linoleic acid, including sunflower seed supplementation, promotes increase in conception rates in cows. We aimed to evaluate whether the sunflower seed (linoleic acid source) supplementation in beef donor females alters the plasma concentrations of cholesterol, triglycerides, HDL and LDL, increases the number and quality of oocytes, increases the cleavage rates and determines an improvement in number and quality of in vitro produced blastocysts. Thus, Nelore females were divided into two groups of 15 animals to receive supplementation with or without sunflower seed for 57 days. Females underwent follicular aspiration and the oocytes were subjected to in vitro embryo production. There was no difference (p > .1) between control group and group supplemented with sunflower seed on the number of displayed follicles; number of aspired oocytes; recovery rate; cleavage rate; number of embryos; number of blastocysts; embryos number of grades I and II; plasma concentrations of total cholesterol, triglycerides; HDL and LDL. Therefore, sunflower seed supplementation in oocyte donors did not increase the number and quality of oocytes, cleavage rates and the number and quality of blastocysts produced in vitro. © 2018 Blackwell Verlag GmbH.

A total number of 360 Japanese quail (14 days old) were used to study the effect of using 2% garlic as a supplement in order to overcome the adverse effect of adding 4% heated oil on their meat and egg quality. The chicks were equally and randomly arranged into 4 groups, each of three replicates. The first and second groups were supplemented with 4% cotton seed oil and 4% cotton seed oil + 2% garlic, respectively, while in both third and forth groups, cotton seed oil was replaced by 4% heated oil. The body weight and mortality rate were examined weekly. At 42 day of age, 9 birds from each group were slaughtered. Serum cholesterol, triglycerides, T3 and T4 were determined by RIA besides to cholesterol and fatty acid in meat. The experiment was completed with the remaining chicks for another 6 weeks for analysis of egg cholesterol, triglyceride and fatty acids. The data revealed that addition of 2% garlic to both cotton seed and heated oil significantly decreased serum and egg cholesterol and triglycerides and meat cholesterol. In addition, total unsaturated fatty acid showed improvement in both meat and egg

2017-10-01
Due to the difficulty of steel deck pavement asphalt layer compaction caused by the effect of the flexible supporting system (orthotropic steel deck plate), it is usually hard and difficult to control for the site compactness to reach the design goal. The intelligent compaction technology is based on GPS control technology and real-time acquisition of actual compaction tracks, and then forms a cloud maps of compaction times, which guide the roller operator to do the compaction in accordance with the design requirement to ensure the deck compaction technology and compaction quality. From the actual construction situation of actual bridge and checked data, the intelligent compaction technology is significant in guaranteeing the steel deck asphalt pavement compactness and quality stability.

Interventions to attenuate the adverse effects of age-related loss of skeletal muscle and function include increased physical activity and nutritional supplementation. This study tested the hypothesis that nutritional supplementation with whey protein (22 g), essential amino acids (10.9 g, including 4 g leucine), and vitamin D [2.5 μg (100 IU)] concurrent with regular, controlled physical activity would increase fat-free mass, strength, physical function, and quality of life, and reduce the risk of malnutrition in sarcopenic elderly persons. A total of 130 sarcopenic elderly people (53 men and 77 women; mean age: 80.3 y) participated in a 12-wk randomized, double-blind, placebo-controlled supplementation trial. All participants concurrently took part in a controlled physical activity program. We examined body composition with dual-energy X-ray absorptiometry, muscle strength with a handgrip dynamometer, and blood biochemical indexes of nutritional and health status, and evaluated global nutritional status, physical function, and quality of life before and after the 12 wk of intervention. Compared with physical activity and placebo, supplementation plus physical activity increased fat-free mass (1.7-kg gain, P nutritional assessment (P = 0.003), and insulin-like growth factor I (P = 0.002), and lowered C-reactive protein (P = 0.038). Supplementation with whey protein, essential amino acids, and vitamin D, in conjunction with age-appropriate exercise, not only boosts fat-free mass and strength but also enhances other aspects that contribute to well-being in sarcopenic elderly.

Zhu, Li-wei; Ma, Wen-guang; Hu, Jin; Zheng, Yun-ye; Tian, Yi-xin; Guan, Ya-jing; Hu, Wei-min
2015-02-01
Near infrared spectroscopy (NIRS) technology developed fast in recent years, due to its rapid speed, less pollution, high-efficiency and other advantages. It has been widely used in many fields such as food, chemical industry, pharmacy, agriculture and so on. The seed is the most basic and important agricultural capital goods, and seed quality is important for agricultural production. Most methods presently used for seed quality detecting were destructive, slow and needed pretreatment, therefore, developing one kind of method that is simple and rapid has great significance for seed quality testing. This article reviewed the application and trends of NIRS technology in testing of seed constituents, vigor, disease and insect pests etc. For moisture, starch, protein, fatty acid and carotene content, the model identification rates were high as their relative contents were high; for trace organic, the identification rates were low as their relative content were low. The heat-damaged seeds with low vigor were discriminated by NIRS, the seeds stored for different time could also been identified. The discrimination of frost-damaged seeds was impossible. The NIRS could be used to identify health and infected disease seeds, and did the classification for the health degree; it could identify parts of the fungal pathogens. The NIRS could identify worm-eaten and health seeds, and further distinguished the insect species, however the identification effects for small larval and low injury level of insect pests was not good enough. Finally, in present paper existing problems and development trends for NIRS in seed quality detection was discussed, especially the single seed detecting technology which was characteristic of the seed industry, the standardization of its spectral acquisition accessories will greatly improve its applicability.

The Content of Mercury in Herbal Dietary Supplements.
Brodziak-Dopierała, Barbara; Fischer, Agnieszka; Szczelina, Wioletta; Stojko, Jerzy
2018-01-17
The dietary supplement market in Poland has been growing rapidly, and the number of registered products and their consumption increases steadily. Among the most popular and the easiest to get are herbal supplements, available in any supermarket. The aim of this paper was to investigate the mercury content in the herbal supplements. The dietary supplements that have been examined (24) are available on the Polish market and contain one or more herbal ingredients. Supplements were pulverized in porcelain mortar and identified by AMA 254 atomic absorption spectrometer. The range of variations for all tested supplements was within 0.02-4293.07 μg/kg. The arithmetic mean of the total result was 193.77 μg/kg. A higher mercury content then this mean was found in preparations-bamboo shoots and alga Chlorella pyrenoidosa. The studies have shown that mercury is present in every examined herbal supplement, and its content exceeds in two preparations (with bamboo and alga) the permissible limit of 0.10 mg/kg. There were statistically significant differences in the occurrence of mercury depending on the herbal ingredient in the supplement. The lowest content was found in the preparation with Tanacetum parthenium and the highest with bamboo shoots. The mercury content in the tested herbal supplements was statistically significant in the form of a supplement-a tablet and a capsule. Daily, weekly, monthly, and yearly consumption of mercury with examined supplements was calculated-the results did not exceed the PTWI-provisional tolerable weekly intake of mercury. To increase consumer safety, it is imperative to conduct further research on dietary supplements and implement a stricter quality control of the dietary supplements.

We examined whether Supplemental Nutrition Assistance Program (SNAP) participation changes associations between food insecurity, dietary quality, and weight among US adults. We analyzed adult dietary intake data (n = 8333) from the 2003 to 2010 National Health and Nutrition Examination Survey. Bivariate and multivariable methods assessed associations of SNAP participation and 4 levels of food security with diet and weight. Measures of dietary quality were the Healthy Eating Index 2010, total caloric intake, empty calories, and solid fat; weight measures were body mass index (BMI), overweight, and obesity. SNAP participants with marginal food security had lower BMI (1.83 kg/m2; P < .01) and lower probability of obesity (9 percentage points; P < .05). SNAP participants with marginal (3.46 points; P < .01), low (1.98 points; P < .05), and very low (3.84 points; P < .01) food security had better diets, as illustrated by the Healthy Eating Index. Associations between SNAP participation and improved diet and weight were stronger among Whites than Blacks and Hispanics. Our research highlights the role of SNAP in helping individuals who are at risk for food insecurity to obtain a healthier diet and better weight status.

Dried, irradiated sewage solids as supplemental feed for cattle
Energy Technology Data Exchange (ETDEWEB)
Smith, G.S.; Kiesling, H.E.; Ray, E.E.; Orcasberro, R.; Trujillo, P.; Herbel, C.H.

Sewage solids were collected as primary settled solids and then dried and gamma-irradiated (using /sup 60/Co or /sup 137/Cs) to absorbed dosage of about one megarad to minimize viable parasites and pathogenic organisms. Nutrient composition and bioassays with rumen microbes suggested prospective usage as supplemental feed for ruminants. Short-term experiments with sheep and then with cattle further suggested that usage of nutrients could be beneficial and that accumulation of heavy metals was not excessive. A longer-term feeding trial with cattle fed sewage solids as 20% of diet for 68 days demonstrated that tissue uptake of elements such as Cu, Fe and Pb was measurably increased, but not sufficient to exceed ranges considered normal. Likewise, of 22 refractory organic compounds having toxicological interest, only a few were detectible in adipose tissue and none of these exceeded levels that have been reported in tissues from cattle produced conventionally. In a large-scale experiment, beef cows grazing poor-quality rangeland forage during late gestation-early lactation were given either no spplemental feed or cottonseed meal or experimental supplement comprised of 62% sewage solids. Supplements were provided for 13 weeks until rangeland forage quality improved seasonably. Supplemental cottonseed meal for cows improved weaning weights of calves by about 11% over unsupplemented controls; whereas, supplement with 62% sewage solids improved calf weaning weights by about 7%. Hazards or risks to animals or to human health appear to be slight when sewage solids of this type are fed as supplemental feeds to cattle in production programs of this type.

Experience with ISO quality control in assisted reproductive technology.
Alper, Michael M
2013-12-01
Assisted reproductive technology (ART) programs are complex organizations requiring the integration of multiple disciplines. ISO 9001:2008 is a quality management system that is readily adaptable to an ART program. The value that ISO brings to the entire organization includes control of documents, clear delineation of responsibilities of staff members, documentation of the numerous processes and procedures, improvement in tracking and reducing errors, and overall better control of systems. A quality ART program sets quality objectives and monitors their progress. ISO provides a sense of transparency within the organization and clearer understanding of how service is provided to patients. Most importantly, ISO provides the framework to allow for continual improvement. Copyright © 2013 American Society for Reproductive Medicine. Published by Elsevier Inc. All rights reserved.

Dietary Supplements Commonly Used by Cancer Survivors: Are There Any Benefits?
Marian, Mary J
2017-10-01
Following a cancer diagnosis, dietary supplements are reportedly used by 20%-80% of individuals. Supplements are most commonly used by breast cancer survivors, followed by patients with prostate, colorectal, and lung cancers, which is not surprising since these are the most common types of cancer diagnosed in adults. Reasons cited for such use include improving quality of life, reducing symptoms related to treatment and/or the disease process, and recommendation from medical practitioners; family and friends may also be an influence. However, controversy surrounds the use of dietary supplements, particularly during treatment-specifically, whether supplements affect treatment efficacy is unknown. This article discusses the evidence related to common dietary supplements used to prevent cancer or a recurrence.

The research achievements and trends of spectral technology in fast detection of Camellia sinensis growth process information and tea quality information were being reviewed. Spectral technology is a kind of fast, nondestructive, efficient detection technology, which mainly contains infrared spectroscopy, fluorescence spectroscopy, Raman spectroscopy and mass spectroscopy. The rapid detection of Camellia sinensis growth process information and tea quality is helpful to realize the informatization and automation of tea production and ensure the tea quality and safety. This paper provides a review on its applications containing the detection of tea (Camellia sinensis) growing status(nitrogen, chlorophyll, diseases and insect pest), the discrimination of tea varieties, the grade discrimination of tea, the detection of tea internal quality (catechins, total polyphenols, caffeine, amino acid, pesticide residual and so on), the quality evaluation of tea beverage and tea by-product, the machinery of tea quality determination and discrimination. This paper briefly introduces the trends of the technology of the determination of tea growth process information, sensor and industrial application. In conclusion, spectral technology showed high potential to detect Camellia sinensis growth process information, to predict tea internal quality and to classify tea varieties and grades. Suitable chemometrics and preprocessing methods is helpful to improve the performance of the model and get rid of redundancy, which provides the possibility to develop the portable machinery. Future work is to develop the portable machinery and on-line detection system is recommended to improve the further application. The application and research achievement of spectral technology concerning about tea were outlined in this paper for the first time, which contained Camellia sinensis growth, tea production, the quality and safety of tea and by-produce and so on, as well as some problems to be solved

Zinc supplements for preventing otitis media.
Gulani, Anjana; Sachdev, Harshpal S
2014-06-29
Otitis media is inflammation of the middle ear and is usually caused by infection. It affects people of all ages but is particularly common in young children. Around 164 million people worldwide have long-term hearing loss caused by this condition, 90% of them in low-income countries. As zinc supplements prevent pneumonia in disadvantaged children, we wanted to investigate whether zinc supplements could also prevent otitis media. To evaluate whether zinc supplements prevent otitis media in adults and children of different ages. We searched CENTRAL (2014, Issue 1), MEDLINE (1950 to February week 4, 2014) and EMBASE (1974 to March 2014). Randomised, placebo-controlled trials of zinc supplements given at least once a week for at least a month for preventing otitis media. Two review authors independently assessed the eligibility and methodological quality of the included trials and extracted and analysed data. We summarised results using risk ratios (RRs) or rate ratios for dichotomous data and mean differences (MDs) for continuous data. We combined trial results where appropriate. No new trials were identified for inclusion in this update. We identified 12 trials for inclusion, 10 of which contributed outcomes data. There were a total of 6820 participants. In trials of healthy children living in low-income communities, two trials did not demonstrate a significant difference between the zinc-supplemented and placebo groups in the numbers of participants experiencing an episode of definite otitis media during follow-up (3191 participants); another trial showed a significantly lower incidence rate of otitis media in the zinc group (rate ratio 0.69, 95% confidence interval (CI) 0.61 to 0.79, n = 1621). A small trial of 39 infants undergoing treatment for severe malnutrition suggested a benefit of zinc for the mean number of episodes of otitis media (mean difference (MD) -1.12 episodes, 95% CI -2.21 to -0.03). Zinc supplements did not seem to cause any serious adverse

The prevalence of vitamin supplementation in ultraendurance triathletes.
Knez, Wade L; Peake, Jonathan M
2010-12-01
Ultraendurance exercise training places large energy demands on athletes and causes a high turnover of vitamins through sweat losses, metabolism, and the musculoskeletal repair process. Ultraendurance athletes may not consume sufficient quantities or quality of food in their diet to meet these needs. Consequently, they may use oral vitamin and mineral supplements to maintain their health and performance. We assessed the vitamin and mineral intake of ultraendurance athletes in their regular diet, in addition to oral vitamin and mineral supplements. Thirty-seven ultraendurance triathletes (24 men and 13 women) completed a 7-day nutrition diary including a questionnaire to determine nutrition adequacy and supplement intake. Compared with dietary reference intakes for the general population, both male and female triathletes met or exceeded all except for vitamin D. In addition, female athletes consumed slightly less than the recommended daily intake for folate and potassium; however, the difference was trivial. Over 60% of the athletes reported using vitamin supplements, of which vitamin C (97.5%), vitamin E (78.3%), and multivitamins (52.2%) were the most commonly used supplements. Almost half (47.8%) the athletes who used supplements did so to prevent or reduce cold symptoms. Only 1 athlete used supplements on formal medical advice. Vitamin C and E supplementation was common in ultraendurance triathletes, despite no evidence of dietary deficiency in these 2 vitamins.

2008-01-01
The National Cancer Institute-sponsored Advanced Technology Quality Assurance (QA) Consortium, which consisted of the Image-Guided Therapy QA Center, Radiation Therapy Oncology Group, Radiological Physics Center, Quality Assurance Review Center, and Resource Center for Emerging Technologies, has pioneered the development of an infrastructure and QA method for advanced technology clinical trials that requires volumetric digital data submission of a protocol patient's treatment plan and verification data. In particular, the Image-Guided Therapy QA Center has nearly 15 years experience in facilitating QA review for Radiation Therapy Oncology Group advanced technology clinical trials. This QA process includes (1) a data integrity review for completeness of protocol required elements, the format of data, and possible data corruption, and recalculation of dose-volume histograms; (2) a review of compliance with target volume and organ-at-risk contours by study chairs; and (3) a review of dose prescription and dose heterogeneity compliance by the Radiation Therapy Oncology Group Headquarters Dosimetry Group or the Radiological Physics Center dosimetrists (for brachytherapy protocols). This report reviews the lessons learned and the QA challenges presented by the use of advanced treatment modalities in clinical trials requiring volumetric digital data submission

Objective Determine efficacy of three non-hormonal therapies for improving menopause-related quality of life (QOL) in women with vasomotor symptoms (VMS). Methods 12-week 3×2 randomized, controlled, factorial design trial. Peri- and postmenopausal women, ages 40-62 years, were randomized to yoga (n=107), exercise (n=106), or usual activity (n=142), and also randomized to double-blind comparison of omega-3 (n=177) or placebo (n=178) capsules. Interventions: 1) weekly 90-minute yoga classes with daily at-home practice; 2) individualized facility-based aerobic exercise training 3 times/week; and 3) 0.615 gram omega-3 supplement, 3 times/day. Outcomes: Menopausal Quality of Life Questionnaire (MENQOL) total and domain (VMS, psychosocial, physical and sexual) scores. Results Among 355 randomized women, average age 54.7 years, 338 (95%) completed 12-week assessments. Mean baseline VMS frequency was 7.6/day and mean baseline total MENQOL score was 3.8 (range 1-8 from better to worse) with no between-group differences. For yoga compared to usual activity, baseline to 12-week improvements were seen for MENQOL total -0.3 (95% CI -0.6 to 0.0, p=0.02), and VMS (p=0.02) and sexuality (p=0.03) domain scores. For exercise and omega-3 compared to controls, improvements in baseline to 12-week total MENQOL scores were not observed. Exercise showed benefit in the MENQOL physical domain score at 12-weeks (p=0.02). Conclusion All women become menopausal and many seek medical advice on ways to improve quality of life; little evidence-based information exists. We found, among healthy sedentary menopausal women, yoga appears to improve menopausal QOL - the clinical significance of our finding is uncertain due to modest effect. PMID:24215858

Exposure of rabbit bucks to summer heat stress reduces their homeostasis and semen quality leading to a temporal subfertility. The potentiality of ethanolic extract of Moringa oleifera leaves (M. oleifera ethanolic extract (MLEE)) to reduce negative impacts of heat stress on physiological and semen quality traits was investigated. A total of 28 adult V-line rabbit bucks were randomly distributed among four experimental groups of seven rabbits each. The first group received water (placebo) and served as a control (M0). The other three groups were given orally MLEE at levels of 50 (M50), 100 (M100) and 150 (M150) mg/kg BW every other day for 12 consecutive weeks during the summer season. Chemical constituents of MLEE were detected by gas chromatography/MS. During the experimental period, ambient temperature and relative humidity were recorded daily and were used to estimate temperature and humidity index. Feed intake, BW, rectal temperature were recorded and blood serum biochemical attributes were determined. Semen samples were collected weekly and were analyzed for semen quality traits. Results showed that MLEE contained high percentages of long-chain fatty acids and antioxidant agents. Feed intake and BW were not affected significantly by the treatment, however rectal temperature was decreased significantly by 0.42°C, 0.24°C and 0.40°C in the M50, M100 and M150 groups, respectively, compared with the M0 group. Treatment with 50 mg/kg BW increased concentration of serum albumin (115%; P<0.05), total antioxidant capacity (132%; P<0.05) and testosterone (160%; P=0.098) as well as seminal plasma initial fructose (127%; P=0.092) compared with the control group. Compared with the control, MLEE supplementation with 50, 100 and 150 mg/kg BW increased significantly sperm concentration by 118%, 151% and 158%, sperm progressive motility by 117%, 120% and 118%, sperm viability by 129%, 137% and 127%, sperm normal morphology by 114%, 113% and 114%, intact acrosome sperm by

Is selenium supplementation in autoimmune thyroid diseases justified?
Winther, Kristian H; Bonnema, Steen J; Hegedüs, Laszlo
2017-10-01
This review provides an appraisal of recent evidence for or against selenium supplementation in patients with autoimmune thyroid diseases, and discusses possible effect mechanisms. Epidemiological data suggest an increased prevalence of autoimmune thyroid diseases under conditions of low dietary selenium intake. Two systematic reviews have evaluated controlled trials among patients with autoimmune thyroiditis and report that selenium supplementation decreases circulating thyroid autoantibodies. The immunomodulatory effects of selenium might involve reducing proinflammatory cytokine release. However, clinically relevant effects of selenium supplementation, including improvement in quality of life, are more elusive. In Graves' disease, some, but not all, trials indicate that adjuvant selenium supplementation enhances the restoration of biochemical euthyroidism, and might benefit patients with mild Graves' orbitopathy. The use of selenium supplementation as adjuvant therapy to standard thyroid medication may be widespread, but a growing body of evidence yields equivocal results. The available evidence from trials does not support routine selenium supplementation in the standard treatment of patients with autoimmune thyroiditis or Graves' disease. However, correction of moderate to severe selenium deficiency may offer benefits in preventing, as well as treating, these disorders. Molecular mechanisms have been proposed, but further studies are needed.

Avedis Donabedian defined the quality of care as the kind of care, which is expected to maximize an inclusive measure of patient welfare, after taking into account the balance of expected gains and losses associated with the process of care in all its segments. According to the World Medical Assembly, physicians and health care institutions have an ethical and professional obligation to strive for continuous quality improvement of services and patient safety with the ultimate goal to improve both individual patient outcomes as well as population health. Health technology assessment (HTA) is a multidisciplinary process that summarizes information about the medical, social, economic and ethical issues related to the use of a health technology in a systematic, transparent, unbiased, robust manner, with the aim to formulate safe and effective health policies that are patient focused and seek to achieve the highest value. The Agency for Quality and Accreditation in Health was established in 2007 as a legal, public, independent, nonprofit institution under the Act on Quality of Health Care. The Agency has three departments: Department of Quality and Education, Department of Accreditation, and Department of Development, Research, and Health Technology Assessment. According to the Act, the Agency should provide the procedure of granting, renewal and cancellation of accreditation of healthcare providers; proposing to the Minister, in cooperation with professional associations, the plan and program for healthcare quality assurance, improvement, promotion and monitoring; proposing the healthcare quality standards as well as the accreditation standards to the Minister; keeping a register of accreditations and providing a database related to accreditation, healthcare quality improvement, and education; providing education in the field of healthcare quality assurance, improvement and promotion; providing the HTA procedure and HTA database, supervising the healthcare insurance

Ghasemi-Varnamkhasti, Mahdi; Mohtasebi, Seyed Saeid; Siadat, Maryam; Balasubramanian, Sundar
2009-01-01
Over the last twenty years, newly developed chemical sensor systems (so called "electronic noses") have made odor analyses possible. These systems involve various types of electronic chemical gas sensors with partial specificity, as well as suitable statistical methods enabling the recognition of complex odors. As commercial instruments have become available, a substantial increase in research into the application of electronic noses in the evaluation of volatile compounds in food, cosmetic and other items of everyday life is observed. At present, the commercial gas sensor technologies comprise metal oxide semiconductors, metal oxide semiconductor field effect transistors, organic conducting polymers, and piezoelectric crystal sensors. Further sensors based on fibreoptic, electrochemical and bi-metal principles are still in the developmental stage. Statistical analysis techniques range from simple graphical evaluation to multivariate analysis such as artificial neural network and radial basis function. The introduction of electronic noses into the area of food is envisaged for quality control, process monitoring, freshness evaluation, shelf-life investigation and authenticity assessment. Considerable work has already been carried out on meat, grains, coffee, mushrooms, cheese, sugar, fish, beer and other beverages, as well as on the odor quality evaluation of food packaging material. This paper describes the applications of these systems for meat quality assessment, where fast detection methods are essential for appropriate product management. The results suggest the possibility of using this new technology in meat handling.

Biotin (D-biotin) was supplemented to F1 Wagyu/Black Angus steers fed a wheat-based ration to evaluate the effect on meat quality. One hundred and eight steers of known Wagyu sire lines were assigned to three biotin treatments (0, 10 and 20mg/head/day) with each treatment replicated four times using an unfasted liveweight of 410.5kg (±24.42 SD). Biotin supplementation had no effect (P>0.05) on beef marbling standard at either the 5/6th or 10/11th rib quartering site, 10/11th rib intra-muscular fat percentage, intra-muscular fat fatty acid composition or adipose melting points. Wagyu genotype had an effect (P<0.05) on beef marbling standard and intra-muscular fat percentage at the 10/11th rib, inter-muscular and intra-muscular melting point and fatty acid composition of intra-muscular fat. A significant (P<0.001) but poor correlation existed between beef marbling standard and intra-muscular fat percentage (R(2)=0.198). Total conjugated linoleic acid had a highly significantly (P<0.0001) positive correlation to intra-muscular fat percentage (R(2)=0.446).

This review examines the use of amperometric electrochemical gas sensors for monitoring inorganic gases that affect urban air quality. First, we consider amperometric gas sensor technology including its development toward specifically designed air quality sensors. We then review recent academic and research organizations' studies where this technology has been trialed for air quality monitoring applications: early studies showed the potential of electrochemical gas sensors when colocated with reference Air Quality Monitoring (AQM) stations. Spatially dense networks with fast temporal resolution provide information not available from sparse AQMs with longer recording intervals. We review how this technology is being offered as commercial urban air quality networks and consider the remaining challenges. Sensors must be sensitive, selective, and stable; air quality monitors/nodes must be electronically and mechanically well designed. Data correction is required and models with differing levels of sophistication are being designed. Data analysis and validation is possibly the biggest remaining hurdle needed to deliver reliable concentration readings. Finally, this review also considers the roles of companies, urban infrastructure requirements, and public research in the development of this technology.

The quality of high-energy X-ray beams
International Nuclear Information System (INIS)
LaRiviere, P.D.
1989-01-01
Supplement 17 of the British Journal of Radiology is a survey of central-axis depth doses for radiotherapy machines, patterned largely on BJR Supplement 11 (1972). Inspection of high-energy X-ray depth doses for a 10 x 10 cm field at an SSD of 100 cm disclosed large differences between the two sets of data, especially for qualities above 8 MV, e.g. a depth dose of 80% at 10 cm is rated at about 19 MV according to BJR Supplement 11, and 23 MV according to BJR Supplement 17. It was found that Supplement 17 depth-dose data above 8 MV were erratic, but Supplement 11 data could be represented by an analytical expression, providing a unique means of assigning MV quality. It was also found that dose-weighted average energy of the filtered beam plotted smoothly against depth dose. For dosimetric purposes, it is suggested that this parameter be used as a true measure of beam quality, removing discrepancies introduced by the use of nominal MV for this purpose. (author)

Intermittent oral iron supplementation during pregnancy (Review)
Peña-Rosas, Juan Pablo; De-Regil, Luz Maria; Dowswell, Therese; Viteri, Fernando E
2014-01-01
Background Anaemia is a frequent condition during pregnancy, particularly among women from developing countries who have insufficient iron intake to meet increased iron needs of both the mother and the fetus. Traditionally, gestational anaemia has been prevented with the provision of daily iron supplements throughout pregnancy, but adherence to this regimen due to side effects, interrupted supply of the supplements, and concerns about safety among women with an adequate iron intake, have limited the use of this intervention. Intermittent (i.e. one, two or three times a week on non-consecutive days) supplementation with iron alone or in combination with folic acid or other vitamins and minerals has recently been proposed as an alternative to daily supplementation. Objectives To assess the benefits and harms of intermittent supplementation with iron alone or in combination with folic acid or other vitamins and minerals to pregnant women on neonatal and pregnancy outcomes. Search methods We searched the Cochrane Pregnancy and Childbirth Group’s Trials Register (23 March 2012). We also searched the WHO International Clinical Trials Registry Platform (ICTRP) for ongoing studies and contacted relevant organisations for the identification of ongoing and unpublished studies (23 March 2012). Selection criteria Randomised or quasi-randomised trials. Data collection and analysis We assessed the methodological quality of trials using standard Cochrane criteria. Two review authors independently assessed trial eligibility, extracted data and conducted checks for accuracy. Main results This review includes 21 trials from 13 different countries, but only 18 trials (with 4072 women) reported on our outcomes of interest and contributed data to the review. All of these studies compared daily versus intermittent iron supplementation. Three studies provided iron alone, 12 iron+folic acid and three more iron plus multiple vitamins and minerals. Their methodological quality was mixed

Characterization of inorganic components in nutritional supplements by neutron activation analysis
International Nuclear Information System (INIS)
Reis, Rogerio Alves de Sousa
2006-01-01
The control of element composition in nutritional supplements is of great interest due to increasingly high consumption and a large diversity and brands of these products offered in market. Therefore, there is the necessity to evaluate the element contents in the supplements and to compare with those values declared on the labels. In this study neutron activation analysis (NAA) was applied to evaluate the element composition of 11 commercial nutritional supplement brands bought in natural product drugstores and pharmacies. These samples acquired in capsule or tablet forms were ground to a homogeneous powder. The samples were irradiated together with the elemental standards in the IEA-R1 nuclear research reactor. Irradiations of 8 h under a thermal neutron flux of 5 x 10 12 n cm -2 s -1 were carried out for Ca, Co, Cr, Fe, Se and Zn determinations. For Cu, K and Na determinations thermal neutron flux of 1 x 10 12 n cm -s-1 was used and, the exposure time was 1h. The induced gamma activities were measured using a hyper pure Ge detector coupled to a gamma ray spectrometer. The obtained results compared with the values of the labels of nutritional supplements presented good agreement for most of the elements. Toxic elements such as As, Cd, Hg and Sb were not detected in the samples. For quality control of the analytical data, certified reference materials NIST 1400 Bone Ash and NIST 1633b Coal Fly Ash provided by the National Institute of Standards and Technology were also analysed. Accuracy and precision of these results were evaluated. The obtained Z score values were lower than 2 indicating that the data are within the ranges of certified values at 95% confidence level (author)

The fruit of Ligustrum lucidum (FLL, Nuzhenzi in Chinese) is an important traditional medicine, and have attracted significant research attention because of their various biological activities. However, there are few research reports available on the use of FLL as a feed additive in livestock nutrition, particularly in layers. This study was conducted to determine the effects of supplementation of the diet of laying hens with FLL on laying performance, egg quality and blood metabolites. A total of 360 72-week-old hens were allocated to three dietary treatments (eight replications of 15 hens/treatment group) and were fed either a control diet or a diet supplemented with an inclusion level of 0.25% or 0.50% of FLL powder in the final feed, until 78 weeks of age. Hens were housed in a three-tier cage system. Feed and water were provided ad libitum. Blood samples and eggs were collected at the end of the experiment. The results showed that dietary supplementation with FLL did not affect egg weight, feed conversion ratio, eggshell thickness, albumen height, egg yolk color, eggshell breaking strength or egg shape index. However, FLL supplementation significantly decreased (Phens fed FLL compared with the control group. It can be concluded that FLL, at a supplementation level of 0.25% final feed, can be used as an effective feed additive to improve the performance of laying hens during the late laying period.

One hundred and twenty eight, 28-weeks-old Lohmann LSL hybrid layers were used in this experiment, which lasted 12 weeks to investigate the effect of propolis supplementation on the productive performance, egg quality traits and haematological variables of laying hens. All hens were randomly classified into four equal experimental groups, eight replicates (4 birds/each). Hens in group 1 were fed on a commercial diet and considered as control group, while those in groups 2, 3 and 4 were fed on the same commercial diet and supplemented with 250, 500 and 1000 mg propolis/kg diet. The obtained results revealed that daily feed consumption/hen increased insignificantly with increasing propolis level than that of the control group. Regarding the means of egg mass and egg production rate, it was observed that the laying hens fed diets containing 250 and 1000 mg propolis/kg significantly (p hens as compared to those in the control. Concerning the haematological parameters, the results showed that the levels of total protein and globulin increased significantly with increasing propolis level, while cholesterol and liver enzymes were significantly decreased (p hens in the treated groups significantly decreased, whereas the lymphocyte count significantly increased, resulting in a decreased H/L ratio than that of the control group. Thus, it could be concluded that the supplementation of 250 mg propolis/kg diet is highly recommended to improving egg production, blood constituent and haematological parameters of the commercial laying hens.

Food insecurity is detrimental to child development, yet little is known about the combined influence of food insecurity and nutritional interventions on child development in low-income countries. We proposed that women assigned to an early invitation time to start a prenatal food supplementation program could reduce the negative influence of food insecurity on maternal-infant interaction. A cohort of 180 mother-infant dyads were studied (born between May and October 2003) from among 3267 in the randomized controlled trial Maternal Infant Nutritional Interventions Matlab, which was conducted in Matlab, Bangladesh. At 8 wk gestation, women were randomly assigned an invitation time to start receiving food supplements (2.5 MJ/d; 6 d/wk) either early (~9 wk gestation; early-invitation group) or at the usual start time (~20 wk gestation; usual-invitation group) for the government program. Maternal-infant interaction was observed in homes with the use of the Nursing Child Assessment Satellite Training Feeding Scale, and food-insecurity status was obtained from questionnaires completed when infants were 3.4-4.0 mo old. By using a general linear model for maternal-infant interaction, we found a significant interaction (P = 0.012) between invitation time to start a prenatal food supplementation program and food insecurity. Those in the usual-invitation group with higher food insecurity scores (i.e., more food insecure) had a lower quality of maternal-infant interaction, but this relationship was ameliorated among those in the early-invitation group. Food insecurity limits the ability of mothers and infants to interact well, but an early invitation time to start a prenatal food supplementation program can support mother-infant interaction among those who are food insecure.

Full Text Available The application of Narrow Web UV-flexographic printing has several advantages compared with offset printing. In particular, they are the lack of the operation of water-ink balance setting in the technological process, the ability to print on a wide range of materials and so on. Though the imprint quality is clearly based on standards in offset printing, there are no clearly indicated requirements for Narrow Web UV flexographic printing. The absence of such requirements on quality parameters of the technological process of Narrow Web UV-Printing predetermined conducting its analysis with the help of expert surveys.

Background Iron-deficiency anaemia is common during childhood. Iron administration has been claimed to increase the risk of malaria. Objectives To evaluate the effects and safety of iron supplementation, with or without folic acid, in children living in areas with hyperendemic or holoendemic malaria transmission. Search methods We searched the Cochrane Infectious Diseases Group Specialized Register; the Cochrane Central Register of Controlled Trials (CENTRAL), published in the Cochrane Library, MEDLINE (up to August 2015) and LILACS (up to February 2015). We also checked the metaRegister of Controlled Trials (mRCT) and World Health Organization International Clinical Trials Registry Platform (WHO ICTRP) up to February 2015. We contacted the primary investigators of all included trials, ongoing trials, and those awaiting assessment to ask for unpublished data and further trials. We scanned references of included trials, pertinent reviews, and previous meta-analyses for additional references. Selection criteria We included individually randomized controlled trials (RCTs) and cluster RCTs conducted in hyperendemic and holoendemic malaria regions or that reported on any malaria-related outcomes that included children younger than 18 years of age. We included trials that compared orally administered iron, iron with folic acid, and iron with antimalarial treatment versus placebo or no treatment. We included trials of iron supplementation or fortification interventions if they provided at least 80% of the Recommended Dietary Allowance (RDA) for prevention of anaemia by age. Antihelminthics could be administered to either group, and micronutrients had to be administered equally to both groups. Data collection and analysis The primary outcomes were clinical malaria, severe malaria, and death from any cause. We assessed the risk of bias in included trials with domain-based evaluation and assessed the quality of the evidence using the Grading of Recommendations Assessment

In addition to the standard interconnections (IC) of the continuous cryostat of the Large Hadron Collider (LHC), there exists a variety of special ones related to specific components and assemblies, such as cryomagnets of the insertion regions, electrical feedboxes and superconducting links. Though they are less numerous, their specificities created many additional IC types, requiring a larger variety of assembly operations and quality control techniques, keeping very high standards of quality. Considerable flexibility and adaptability from all the teams involved (CERN staff, collaborating institutes, contractors) were the key points to ensure the success of this task. This paper first describes the special IC and presents the employed technologies which are generally adapted from the standard work. Then, the organization adopted for this non-repetitive work is described. Examples of non-conformities that were resolved are also discussed. Figures of merit in terms of quality and productivity are given and com...

The quality concern of food and agricultural products has become more and more significant. The related technologies for nondestructive measurement or quality control of food products have been the focus of many researches. Terahertz (THz) radiation, or THz wave, the least explored region of the spectrum, is the electromagnetic wave that lies between mid-infrared and microwave radiation, which has very important research and application values. THz spectroscopy and THz imaging technique are the two main applications of THz wave. During the past decade, THz waves have been used to characterize the electronic, vibrational and compositional properties of solid, liquid and gas phase materials. Recently, THz technology has gained a lot of attention of researchers in various fields from biological spectral analysis to bio-medical imaging due to its unique features compared with microwave and optical waves. In the present paper, the properties of THz wave and its uniqueness in sensing and imaging applications were discussed. The most recent researches on THz technology used in food quality control and agricultural products inspection were summarized. The prospect of this novel technology in agriculture and food industry was also discussed.

To examine the association of the Supplemental Nutrition Assistance Program (SNAP) and diet quality among low-income adults. We examined US nationally representative data from the National Health and Nutrition Examination Surveys 2003-2004, 2005-2006, 2007-2008, and 2009-2010. The data were analyzed from October 7, 2013, to March 1, 2014. The analytic sample consisted of 4211 low-income adults aged 20 to 64 years, of whom 1830 participate in SNAP. We adhered to the National Cancer Institute method in calculating the Healthy Eating Index 2010 and other dietary indicators, such as empty calorie intake. Bivariate and multivariable regression was used to compare SNAP participants and income-eligible nonparticipants among the full sample and subsamples of age, sex, race/ethnicity, and food insecurity. Compared with low-income nonparticipants, adjusted analyses reveal that SNAP participants had lower dietary quality scores overall (42.58 vs 44.36, P≤.0001) and lower scores for fruits and vegetables, seafood and plant proteins (1.55 vs 1.77, P≤.0022), and empty calories (9.03 vs 9.90, P≤.0001), but they exhibited comparable scores on whole grain, refined grain, total dairy, total protein, fatty acid, and sodium intakes. The association between SNAP participation and lower dietary quality was statistically significant among women, Hispanics, young adults, and individuals who were food secure. Our analyses suggest that SNAP participants have lower dietary quality than their income-eligible nonparticipant counterparts. Although SNAP has an important role in providing nutrition assistance to eligible low-income individuals, interventions are warranted to improve the dietary quality of participants.

In this context, the aim of this study was to assess the effect of different periods of the growing season on the technological quality of common bean grains. The experiment was conducted with 25 bean genotypes (carioca [beige with brown stripes] and black commercial group that are part of the Value for Cultivation and Use (Valor de Cultivo e Uso - VCU trials in three growing seasons, namely, the 2009/2010 rainy season, the 2010/2011 dry season and the 2010/2011 winter season, in a randomized block experimental design with three replications in which the following items were assessed: cooking time (CT, water absorption capacity before cooking (Peanc and after cooking (Peapc, percentage of whole grains (PWG, total soluble solids in the broth (TSSb, volume expansion before cooking (EXPVbc and after cooking (EXPVac, and dry grain density (DD, grain density after maceration (SD and grain density after cooking (CD. Assessments showed that the different growing seasons for obtaining grains for the purpose of analysis of technological quality have an effect on the results and on differentiation among genotypes, indicating genotype x environment interaction. They also showed that the genotypes C2-1-6-1, C4-8-1-1, LP04-03, IAC-Imperador, P5-4-4-1 and Pr11-6-4-1-2 had the best results in relation to cooking time in the mean values of the three growing seasons. The use of early selection based on phenotypic correlations that exist among the technological features is not expressive, due to the variation of magnitude among the different growing seasons.

This study evaluated the effect of two concentrate supplementation strategies on performance, metabolic profile and economic evaluation of suckling lambs and ewes in ryegrass (Lolium multiflorum) pasture. Twenty-seven ewes and 45 lambs were divided into three groups: (1) ryegrass pasture without supplementation - control (CON); (2) CON plus supplemented ewes and lambs at 1% of live weight (SEL), and (3) CON plus creep feeding supplemented lambs at 1% of live weight (CSL). Concentrate use increased (p<0.05) average daily gain (ADG) by 19.95% over CON (21.6 and 18.3% for SEL and CSL, respectively). Concentrate use contributed to minimizing forage quality fluctuation and provided greater ADG stability, mainly when ryegrass nutritional content and digestibility decreased. Blood metabolites profiles did not differ between groups, with exception of phosphorus which was higher for CON than SEL, and calcium which was higher for CSL than CON (p<0.05). Compared to CON, stoking rate values were greater to SEL (p<0.05). Compared to CSL, ewe and total stocking rate were greater (p<0.05) to SEL. Considering the control group as break even feed investment, SEL strategy had a positive economic return, while CSL showed economic losses. Concentrate use increased ADG of lambs and decrease the impact of nutrient quality changes of forage on daily gains, but must be considered that supplemental strategy used could affect negatively economic return.

Consumer demand for health information and health services has rapidly evolved to capture and even propel the movement to online health information seeking. Seventeen percent (52 million) of health information internet users will look for information about memory loss, dementia and Alzheimer's disease (AD) (Fox Pew Internet & American life project: Online health search. Report. Pew Research Center. http://pewinternet.org/Reports/2006/Online-Health-Search-2006.aspx 2006, Pew Research Center. http://pewinternet.org/Reports/2011/HealthTopics.aspx 2011). We examined the content of the 25 most frequently retrieved websites marketing AD dietary supplements. We found that the majority of websites and their products claimed AD-related benefits, including improvement and enhancement of function, treatment for AD, prevention of AD, maintenance of function, delayed progression of AD, and decreased symptoms. Supplements were described as effective, natural, powerful or strong, dependable and pure or of high quality. Peer reviewed references to proper scientific studies were infrequent on websites. Statements highlighting the risks of dietary supplements were as common as statements mitigating or minimizing these risks. Different strategies were used to promote supplements such as popular appeals and testimonials. Further enforcement of relevant policy is needed and preparation of clinicians to deal with requests of patients and caregivers is indicated.

A global interest in developing these interventions exists among both for-profit and not-for-profit organisations. It is therefore essential to have internationally accepted standards to assess the quality of their development, process, content, potential bias and method of field testing and evaluation.Scale development study, involving construct, item and scale development, validation and reliability testing.Twenty-five researcher-members of the International Patient Decision Aid Standards Collaboration worked together to develop the instrument (IPDASi. In the fourth Stage (reliability study, eight raters assessed thirty randomly selected decision support technologies.IPDASi measures quality in 10 dimensions, using 47 items, and provides an overall quality score (scaled from 0 to 100 for each intervention. Overall IPDASi scores ranged from 33 to 82 across the decision support technologies sampled (n = 30, enabling discrimination. The inter-rater intraclass correlation for the overall quality score was 0.80. Correlations of dimension scores with the overall score were all positive (0.31 to 0.68. Cronbach's alpha values for the 8 raters ranged from 0.72 to 0.93. Cronbach's alphas based on the dimension means ranged from 0.50 to 0.81, indicating that the dimensions, although well correlated, measure different aspects of decision support technology quality.

Numerous types of self-service technologies have prevailed due to innovations in network and information technology. To hospitals, patient intentions to continue to use the e-appointment system are crucial. Previous investigations discussed only the relationships between the technology readiness of users and their continuance intentions, and ignored the most important mediator, relationship quality. This study explored the relationships among technology readiness, relationship quality, and continuance intention. The research results demonstrated that both optimism and innovativeness significantly and positively influenced continuance intention through the mediating effect of relationship quality. However, discomfort and insecurity hid not significantly influence relationship quality or continuance intention. Finally, theoretical contributions, managerial implications and future research directions were discussed.

The CK/PCr-system, with creatine (Cr) as an energy precursor, plays a crucial role in cellular physiology. In the kidney, as in other organs and cells with high and fluctuating energy requirements, energy-charged phospho-creatine (PCr) acts as an immediate high-energy source and energy buffer, and as an intracellular energy transport vehicle. A maximally filled total Cr (Cr plus PCr) pool is a prerequisite for optimal functioning of the body and its organs, and health. Skeletal- and cardiac muscles of dialysis patients with chronic kidney disease (CKD) are depleted of Cr in parallel with the duration of dialysis. The accompanying accumulation of cellular damage seen in CKD patients lead to a deterioration of musculo-skeletal and neurological functioning and poor quality of life (QOL). Therefore, to counteract Cr depletion, it is proposed to supplement CKD patients with Cr. The anticipated benefits include previously documented improvements in the musculo-skeletal system, brain and peripheral nervous system, as well as improvements in the common comorbidities of CKD patients (see below). Thus, with a relatively simple, safe and inexpensive Cr supplementation marked improvements in quality of life (QOL) and life span are likely reached. To avoid Cr and fluid overload by oral Cr administration, we propose intradialytic Cr supplementation, whereby a relatively small amount of Cr is added to the large volume of dialysis solution to a final concentration of 1-10mM. From there, Cr enters the patient's circulation by back diffusion during dialysis. Because of the high affinity of the Cr transporter (CRT) for Cr affinity for Cr (Vmax of CRT for Cr=20-40μM Cr), Cr is actively transported from the blood stream into the target cells and organs, including skeletal and cardiac muscle, brain, proximal tubules of kidney epithelial cells, neurons, and leukocytes and erythrocytes, which all express CRT and depend on the CK/PCr system. By this intradialytic strategy, only as much Cr

Detection of Cyanotoxins in Algae Dietary Supplements.
Roy-Lachapelle, Audrey; Solliec, Morgan; Bouchard, Maryse F; Sauvé, Sébastien
2017-02-25
Algae dietary supplements are marketed worldwide as natural health products. Although their proprieties have been claimed as beneficial to improve overall health, there have been several previous reports of contamination by cyanotoxins. These products generally contain non-toxic cyanobacteria, but the methods of cultivation in natural waters without appropriate quality controls allow contamination by toxin producer species present in the natural environment. In this study, we investigated the presence of total microcystins, seven individual microcystins (RR, YR, LR, LA, LY, LW, LF), anatoxin-a, dihydroanatoxin-a, epoxyanatoxin-a, cylindrospermopsin, saxitoxin, and β-methylamino-l-alanine in 18 different commercially available products containing Spirulina or Aphanizomenon flos-aquae . Total microcystins analysis was accomplished using a Lemieux oxidation and a chemical derivatization using dansyl chloride was needed for the simultaneous analysis of cylindrospermopsin, saxitoxin, and β-methylamino-l-alanine. Moreover, the use of laser diode thermal desorption (LDTD) and ultra-high performance liquid chromatography (UHPLC) both coupled to high resolution mass spectrometry (HRMS) enabled high performance detection and quantitation. Out of the 18 products analyzed, 8 contained some cyanotoxins at levels exceeding the tolerable daily intake values. The presence of cyanotoxins in these algal dietary supplements reinforces the need for a better quality control as well as consumer's awareness on the potential risks associated with the consumption of these supplements.

Full Text Available The First National Geographical Condition Survey is a predecessor task to dynamically master basic situations of the nature, ecology and human activities on the earth’s surface and it is the brand-new mapping geographic information engineering. In order to ensure comprehensive, real and accurate survey results and achieve the quality management target which the qualified rate is 100 % and the yield is more than 80 %, it is necessary to carry out the quality control and result inspection for national geographical conditions survey on a national scale. To ensure that achievement quality meets quality target requirements, this paper develops the key technology method of “five-in-one” quality control that is constituted by “quality control system of national geographical condition survey, quality inspection technology system, quality evaluation system, quality inspection information management system and national linked quality control institutions” by aiming at large scale, wide coverage range, more undertaking units, more management levels, technical updating, more production process and obvious regional differences in the national geographical condition survey and combining with novel achievement manifestation, complicated dependency, more special reference data, and large data size. This project fully considering the domestic and foreign related research results and production practice experience, combined with the technology development and the needs of the production, it stipulates the inspection methods and technical requirements of each stage in the quality inspection of the geographical condition survey results, and extends the traditional inspection and acceptance technology, and solves the key technologies that are badly needed in the first national geographic survey.

The effect of irradiation at doses of 125, 250, 375, and 500 Gy, commonly used for quarantine treatment, on the quality of Maroc-late orange, the most common export variety of Morocco was investigated. In the first study fruits were irradiated without any previous cold conditioning treatment as practiced by the export trade for quarantine purposes. In the second study fruits obtained from the normal chain after conditioning was irradiated. Storage of irradiated fruits was studied at room temperature and 10 deg. C at 0 deg. C in case of control fruits. The parameters studied included juice yield, total solids, reducing and total sugars, total acids and volatile acids, dry weight and weight loss. The results showed that irradiation did not affect the technological quality of citrus fruits during four weeks storage. The result thus far points to the possibility for the successful application of irradiation as an alternative quarantine treatment to the classical methods, which result in browning of the peel. The browning phenomenon could be controlled by waxing and will be the subject of a future study. (author)

Two experiments were conducted to determine the effect of ruminal protein degradability and supplementation frequency on intake, apparent digestibility, N retention, and nutrient flux across visceral tissues of lambs fed a low-quality forage diet. In both experiments, wethers were fed a basal diet of mature crested wheatgrass hay (4.2% CP) for ad libitum consumption plus 1 of 4 supplements: 1) a high RDP supplement provided daily (RDP-D), 2) the high RDP supplement provided on alternate days (RDP-A), 3) a high RUP provided on alternate days (RUP-A), or 4) a 50:50 mixture of the RDP and RUP supplements provided on alternate days. In Exp. 1, 12 lambs (29.9 +/- 2.7 kg initial BW) were used. Forage OM, NDF, and ADF intake were not affected by treatment. Total tract digestibilities (OM, NDF, ADF, and N) were unaffected (P >or= 0.15) by treatment. Neither protein degradability nor supplementation frequency had an effect (P >or= 0.52) on N retention. In Exp. 2, 15 lambs (34 +/- 4 kg initial BW) fitted with indwelling catheters in a hepatic vein, the hepatic portal vein, a mesenteric vein, and a mesenteric artery were used. Release of ammonia N by the portal-drained viscera (PDV) was reduced (P = 0.004) in alternate-day-supplemented lambs compared with RDP-D. Consequently, hepatic uptake of ammonia N was least (P = 0.003) in all alternate-day lambs. Alpha-amino nitrogen (AAN) release by the PDV and hepatic uptake of AAN were not affected by treatment or supplementation frequency. Additionally, hepatic output and PDV uptake of urea N were not affected by treatment. Hepatic N uptake (ammonia N + AAN) accounted for urea synthesized by the liver in all treatments; however, hepatic urea synthesis was approximately 4.5-fold less for RUP-A lambs. This suggests that the provision of AA as RUP may provide a delay in ureagenesis, thus altering the timing of N recycling.

Previous research has evaluated technology-based service encounters (TBSEs) in the delivery of health care by assessing patient satisfaction. This study examined service quality and perceived value of TBSEs used in health organisations from the perspective of clinical staff, with staff technology readiness as a moderator. A quantitative survey was conducted in Taiwan, across private and public healthcare organisations. Results showed that TBSEs had a direct effect on service quality and perceived value, which in turn had a direct effect on staff satisfaction in using TBSEs. However, service quality had no effect on perceived value when moderated by technology readiness. Theoretical and managerial implications of these findings are discussed.

Few rejuvenation and antiaging markers are used to evaluate food supplements. We measured three markers in peripheral blood to evaluate the antiaging effects of a food supplement containing placental extract. Samples were evaluated for CD34(+) cells, insulin-like growth factor 1 (IGF1), and telomerase activity, which are all markers related to aging. To control the quality of this food supplement, five active components were monitored. In total, we examined 44 individuals who took the food supplement from 1.2 months to 23 months; the average number of CD34(+) cells was almost 6-fold higher in the experimental group compared with the control group. Food supplement intake did not change serum IGF1 levels significantly. Finally, the average telomerase activity was 30% higher in the subjects taking this food supplement. In summary, our results suggest that the placental extract in the food supplement might contribute to rejuvenation and antiaging.

The prevalence of dietary supplement use varies largely among populations, and previous studies have indicated that it is high in the Danish population compared with other European countries. The diversity in supplement use across countries indicates that cultural and environmental factors could influence the use of dietary supplements. Only few studies investigating the use of dietary supplements have been conducted in the Danish population. The present cross-sectional study is based on 54,948 Danes, aged 50-64 years, who completed self-administrated questionnaires on diet, dietary supplements and lifestyle between 1993 and 1997. A health index including smoking, physical activity, alcohol and diet, and a metabolic risk index including waist circumference, urinary glucose and measured hypertension were constructed. Logistic regression was used to investigate these determinants in relation to the intake of dietary supplements. We found that 71 % of the participants were dietary supplement users; female sex, older age groups and higher educated participants were more likely to be users of any dietary supplements. One additional point in the health index was associated with 19, 16 and 9 % higher likelihood of being user of any, more common and less common supplements, respectively. In the metabolic risk index, one additional point was associated with 17 and 16 % lower likelihood of being user of any supplement and more common supplements, respectively. No significant association was found for less common supplement use. In conclusion, those with the healthiest lifestyle were more likely to use dietary supplements. Thus, lifestyle and dietary composition should be considered as confounders on supplement use and health outcomes.

The author argues that to examine the relationship between technology use and student outcomes, the quality of technology use--how, and what, technology is used--is a more significant factor than the quantity of technology use--how much technology is used. This argument was exemplified by an empirical study that used both angles to examine the…

Full Text Available Production and quality of milk from dairy cows grazing exclusively on Mombasa grass pasture, during the spring-summer period and fed roughage supplementations, during the autumn-winter, were evaluated in two consecutive years. The pasture of 11.4 ha was divided into 57 paddocks of 2,000 m² each, including three replications with 19 paddocks each. The pasture was managed with two occupation days and 36 resting days. During the spring-summer period, cows received only grass pasture. In the autumn-winter period, they had access to Mombasa grass pasture and received roughage supplementations (black oat pasture; sorghum silage or sugarcane + urea and pasture every 28 days, alternately. The animals had access to mineral mix and water and received 500 g of concentrated in each of the two milking times. The experimental design used was for response to continuous flow in rotational trial, similar to the Latin square model. In the spring-summer period, the average milk production was 12.2±2.2 and 14.0±3.8 kg/cow per day; for the autumn-winter period, the milk production was 13.5±2.9 and 12.1±2.5 kg/cow per day in the black oat pasture; 11.8±2.5 and 10.9±2.3 kg/cow per day in the sorghum silage and 11.3±1.8 and 8.4±1.5 kg/cow per day in the sugarcane + urea, for 1st and 2nd years evaluated, respectively. The black oat was the roughage supplementation that yielded the highest average daily milk production. There were no differences in the milk chemical composition between roughage supplementations.

The number of botanical dietary supplements in the market has recently increased primarily due to increased health awareness. Standardization and quality control of the constituents of these plant extracts is an important topic, particularly when such ingredients are used long term as dietary supplements, or in cases where higher doses are marketed as drugs. The development of fast, comprehensive, and effective untargeted analytical methods for plant extracts is of high interest. Nuclear magnetic resonance spectroscopy and mass spectrometry are the most informative tools, each of which enables high-throughput and global analysis of hundreds of metabolites in a single step. Although only one of the two techniques is utilized in the majority of plant metabolomics applications, there is a growing interest in combining the data from both platforms to effectively unravel the complexity of plant samples. The application of combined MS and NMR in the quality control of nutraceuticals forms the major part of this review. Finally I will look at the future developments and perspectives of these two technologies for the quality control of herbal materials.

Decision-making patterns for dietary supplement purchases among women aged 25 to 45 years.
Miller, Carla K; Russell, Teri; Kissling, Grace
2003-11-01
Women frequently consume dietary supplements but the criteria used to select supplements have received little investigation. This research identified the decision-making criteria used for dietary supplements among women aged 25 to 45 years who consumed a supplement at least four times per week. Participants (N=51) completed an in-store shopping interview that was audiotaped, transcribed, and analyzed qualitatively for the criteria used to make supplement selections. Qualitative analysis revealed 10 key criteria and the number of times each person used each criterion was quantified. Cluster analysis identified five homogeneous subgroups of participants based on the criteria used. These included brand shopper, bargain shopper, quality shopper, convenience shopper, and information gatherer. Supplement users vary in the criteria used to make point-of-purchase supplement selections. Dietetics professionals can classify supplement users according to the criteria used to tailor their nutrition counseling and better meet the educational needs of consumers.

Recent advances in cooled-semen technology.
Aurich, Christine
2008-09-01
The majority of horse registries approve the use of artificial insemination, and horse breeding has widely taken benefit from the use of cooled-stored semen. New insights into cooled-semen technology open possibilities to reduce problems such as impaired semen quality after cooled-storage in individual stallions. The stallion itself has major impacts on quality and fertility of cooled-stored semen. Dietary supplementation of antioxidants and polyunsaturated fatty acids improves semen quality in a variety of species, but only few studies on this topic exist in the horse. Proper semen collection and handling is the main key to the maintenance of semen quality during cooled-storage. Semen collection should be achieved by minimal sexual stimulation with a single mount; this results in high sperm concentration, low content of seminal plasma and minimal contamination with bacteria. Milk-based semen extenders are most popular for semen processing and storage. The development of more defined extenders containing only the beneficial milk ingredients has made extender quality more constant and reliable. Semen is often centrifuged to decrease the seminal plasma content. Centrifugation results in a recovery rate of only 75% of spermatozoa in the semen pellet. Recovery rates after centrifugation may be improved with use of a "cushion technique" allowing higher centrifugation force and duration. However, this is not routinely used in cooled-semen technology. After slow-cooling, semen-storage and shipping is best performed at 5 degrees C, maintaining semen motility, membrane integrity and DNA integrity for up to 40 h after collection. Shipping containers created from Styrofoam boxes provide maintenance of semen quality at low cost.

Measuring the value of medical imaging is challenging, in part, due to the lack of conceptual frameworks underlying potential mechanisms where value may be assessed. To address this gap, this article proposes a framework that builds on the large body of literature on quality of hospital care and the classic structure-process-outcome paradigm. The framework was also informed by the literature on adoption of technological innovations and introduces 2 distinct though related aspects of imaging technology not previously addressed specifically in the literature on quality of hospital care: adoption (a structural hospital characteristic) and use (an attribute of the process of care). The framework hypothesizes a 2-part causality where adoption is proposed to be a central, linking factor between hospital structural characteristics, market factors, and hospital outcomes (ie, quality and efficiency). The first part indicates that hospital structural characteristics and market factors influence or facilitate the adoption of high technology medical imaging within an institution. The presence of this technology, in turn, is hypothesized to improve the ability of the hospital to deliver high quality and efficient care. The second part describes this ability throughout 3 main mechanisms pointing to the importance of imaging use on patients, to the presence of staff and qualified care providers, and to some elements of organizational capacity capturing an enhanced clinical environment. The framework has the potential to assist empirical investigations of the value of adoption and use of medical imaging, and to advance understanding of the mechanisms that produce quality and efficiency in hospitals.

Full Text Available This article considers the expert system (ES as a subsystem of management information system technology of sausage products of a given quality. Given the typical structure of an automated expert system, upgraded under a set of interrelated operations of the technological process of production of cooked sausages. Describes the development of two main blocks of this expert system – a database and knowledge base, creating an information space. The work of ES is a sequence of steps, each of which is selected from the database for a rule that applies to the current contents of the working set. The cycle ends when withdrawn or denied the target claim. In our case, the system is designed as a system with direct output, in which the known facts is found the conclusion which from these facts follows. If such a conclusion is found, it is entered into working memory. The knowledge base of an expert system is created as a set of separate entities. The set of these entities allows you to generate objects of study, rules that they can conform, and recommendations for meeting these rules. A set of such entities with their attributes and relationships can be represented as a set of tuples. For the implementation of this approach developed an automated expert system of control of technological process of production of meat and sausage products – the program complex (PC “MulTimit Expert”. The effectiveness of using the developed expert system to control the technology of sausage products of a given quality are considered in one of the examples of the identification of technology defects in the formulation of cooked sausages "Capital", containing large amounts of fatty raw materials. The results of the research as a whole showed that the recommendations of the developed expert system make it possible to improve the quality of the ready-to-eat meat product, increase the water retention coefficient characterizing the moisture retention capacity of the

We examined effects of supplementation of food quantity and quality (=enhanced methionine) on hematologic and immunologic parameters of wild, but enclosed, adult male cotton rats (Sigmodon hispidus) in north-central Oklahoma. Sheet metal enclosures were stocked with a high density of wild-caught cotton rats (160 animals/ha) and randomly assigned a treatment of no supplementation, mixed-ration supplementation or methionine-enhanced supplementation. Aside from small increases in counts of red blood cells and hematocrit levels, most indices of erythrocytic characteristics were not affected by supplementation with the mixed-ration or enhanced methionine. In contrast, platelet counts were highest in mixed-ration and methionine treatments and counts of total white blood cells were highest with methionine supplementation, albeit relative proportions of different leukocytes did not differ among treatments. Immunologically, neither delayed-type hypersensitivity response nor hemolytic-complement activity differed among treatments. Supplementation of food quantity and quality did not broadly affect hematologic parameters and immune function of male cotton rats, but enhanced platelet and leukocyte counts may confer advantages to overall health. Clarification of the role of such effects on population limitation or regulation requires additional research.

The adoption of voluntary nutrient reduction technologies among Danish farmers is relatively low despite the introduction of a number of incentives to do so. With data from 267 farmers, this study analyzes the level of adoption of these technologies and the farmers’ perception of water quality......, existing regulatory measures and their implementation strategies. In general, farmers perceive the water quality to be above average and indicate a strong opposition to penalties for non-compliance. Results of two ordered probit models on adoption and perception show a significant importance of farm...... and soil types, farm size and slopes and information availability. These findings point to the need for increased information dissemination on water quality requirements both at national and regional levels and technical and institutional support for the existing and future incentives....

Full Text Available BACKGROUND: Many observational studies linked vitamin D to cardiometabolic risks besides its pivotal role in musculoskeletal diseases, but evidence from trials is lacking and inconsistent. AIM: To determine whether Vitamin D supplementation in urban premenopausal women with vitamin D deficiency can improve cardiometabolic risks and health-related quality of life (HRQOL. DESIGN: A double-blind randomized controlled trial was conducted in Kuala Lumpur, Malaysia. A total of 192 vitamin D deficient (0.05 between two groups. There was a small but significant improvement in HRQOL in the components of vitality (mean difference: 5.041; 95% CI: 0.709 to 9.374 and mental component score (mean difference: 2.951; 95% CI: 0.573 to 5.329 in the intervention group compared to placebo group. CONCLUSION: Large and less frequent dosage vitamin D supplementation was safe and effective in the achievement of vitamin D sufficiency. However, there was no improvement in measured cardiometabolic risk factors in premenopausal women. Conversely vitamin D supplementation improves some components of HRQOL.

Full Text Available The growing popularity of botanical dietary supplements (BDS has been accompanied by concerns regarding the quality of commercial products. Health care providers, in particular, have an interest in knowing about product quality, in view of the issues related to herb-drug interactions and potential side effects. This study assessed whether commercial formulations of saw palmetto, kava kava, echinacea, ginseng and St. John's wort had consistent labeling and whether quantities of marker compounds agreed with the amounts stated on the label. We purchased six bottles each of two lots of supplements from nine manufacturers and analyzed the contents using established commercial methodologies at an independent laboratory. Product labels were found to vary in the information provided, such as serving recommendations and information about the herb itself (species, part of the plant, marker compound, etc. With regard to marker compound content, little variability was observed between different lots of the same brand, while the content did vary widely between brands (e.g. total phenolic compounds in Echinacea ranged from 3.9–15.3 mg per serving; total ginsenosides in ginseng ranged from 5.3–18.2 mg per serving. Further, the amounts recommended for daily use also differed between brands, increasing the potential range of a consumer's daily dose. Echinacea and ginseng were the most variable, while St. John's wort and saw palmetto were the least variable. This study highlights some of the key issues in the botanical supplement market, including the importance of standardized manufacturing practices and reliable labeling information. In addition, health care providers should keep themselves informed regarding product quality in order to be able to appropriately advise patients utilizing both conventional and herbal medicines.

Engineering research, development and technology: Thrust area report FY 91
International Nuclear Information System (INIS)
1991-01-01
The mission of the Engineering Research, Development, and Technology Program at Lawrence, Livermore National Laboratory (LLNL) is to develop the technical staff and the technology needed to support current and future LLNL programs. To accomplish this mission, the Engineering Research, Development, and Technology Program has two important goals: (1) to identify key technologies and (2) conduct high quality work to enhance our capabilities in these key technologies. To help focus our efforts, we identify technology thrust areas and select technical leaders for each area. The thrust areas are integrated engineering activities and, rather than being based on individual disciplines, they are staffed by personnel from Electronics Engineering, Mechanical Engineering, and other LLNL organizations, as appropriate. The thrust area leaders are expected to establish strong links to LLNL program leaders and to industry; to use outside and inside experts to review the quality and direction of the work; to use university contacts to supplement and complement their efforts; and to be certain that we are not duplicating the work of others. The thrust area leader is also responsible for carrying out the work that follows from the Engineering Research, Development, and Technology Program so that the results can be applied as early as possible to the needs of LLNL programs. This annual report, organized by thrust area, describes activities conducted within the Program for the fiscal year, 1991. Its intent is to provide timely summaries of objectives, theories, methods, and results

Culture of human islets before clinical transplantation or distribution for research purposes is standard practice. At the time the Edmonton protocol was introduced, clinical islet manufacturing did not include culture, and human serum albumin (HSA), instead of fetal bovine serum (FBS), was used during other steps of the process to avoid the introduction of xenogeneic material. When culture was subsequently introduced, HSA was also used for medium supplementation instead of FBS, which was typically used for research islet culture. The use of HSA as culture supplement was not evaluated before this implementation. We performed a retrospective analysis of 103 high-purity islet preparations (76 research preparations, all with FBS culture supplementation, and 27 clinical preparations, all with HSA supplementation) for oxygen consumption rate per DNA content (OCR/DNA; a measure of viability) and diabetes reversal rate in diabetic nude mice (a measure of potency). After 2-day culture, research preparations exhibited an average OCR/DNA 51% higher (p < 0.001) and an average diabetes reversal rate 54% higher (p < 0.05) than clinical preparations, despite 87% of the research islet preparations having been derived from research-grade pancreata that are considered of lower quality. In a prospective paired study on islets from eight research preparations, OCR/DNA was, on average, 27% higher with FBS supplementation than that with HSA supplementation (p < 0.05). We conclude that the quality of clinical islet preparations can be improved when culture is performed in media supplemented with serum instead of albumin.

Korea is currently developing the HTR coated particle fuel technology in view of its long-term Nuclear Hydrogen Production Technology Development and Demonstration (NHDD) Project, which was launched in 2004, of an extensive R and D program on technology development for a hydrogen production by a VHTR. The current NHDD Project essentially covers the R and D works on the core and reactor system analysis, thermo-hydraulics and safety, coated particle fuel technology, material and component aspects and the hydrogen production technology by using the so-called Sulfur-Iodine Process (S-I Process). As a part of the NHDD Project, the fundamental technology for the coated particle fuel has been being developed, which consist of UO 2 kernel fabrication, pyrolytic carbon (PyC) and silicon carbide (SiC) coating technology, an in-reactor performance model development of a coated particle fuel and a preliminary preparative study for the irradiation tests of the coated particle fuel specimens in the HANARO reactor. In parallel with the development of fabrication process technology of the coated particle fuel, namely, kernel fabrication and coating processes, the characterization techniques for the important characteristics and quality control (QC) methods of the products after each process step were established. This paper deals with the works carried out for the development of the characterization technologies and establishment of the QC techniques for the coated fuel particles. Emphasis is given to the selection and development of the laboratory equipment and apparatus for the development of the methods of the characterizations and relevant QC methods

Factors to consider in the selection of a calcium supplement.
Shangraw, R F
1989-01-01
Calcium supplements are widely used, yet many questions remain as to the absorption of various calcium salts. Because the solubility of many calcium salts is dependent upon pH, the type of salt used, the condition of the patient, and the time of administration should be considered. Studies show that many calcium supplements on the market today do not meet standards of quality established in the "U.S. Pharmacopeia" (USP). Consumers must be discerning about the products they purchase. Calcium s...

Full Text Available A self-control, randomized, and open-label clinical trial was performed to test the effects of the unicellular green algae Chlorella and hot water extract supplementation on quality of life (QOL in patients with breast cancer. Forty-five female patients with breast cancer who were living at home and not hospitalized were randomly assigned to 3 groups receiving vitamin mix tablet (control, Chlorella granules (test food-1, or Chlorella extract drink (test food-2 daily for one month. The Functional Assessment of Cancer Therapy-Breast (FACT-B, the Izumo scale for abdominal symptom-specific QOL, and a narrative-form questionnaire were used to determine outcomes. Data of thirty-six subjects were included for final analysis. FACT-B scores at presupplementation found no significant group differences in all subscales. Scores on the breast cancer subscale in the Chlorella granule group significantly increased during the supplementation period (P=0.042. Fifty percent of the Chlorella extract group reported positive effects by the test food such as reduction of fatigue and improvements of dry skin (P<0.01 versus control group. The findings suggested the beneficial effects of Chlorella on breast cancer-related QOL and of Chlorella extract on vitality status in breast cancer patients. These findings need to be confirmed in a larger study.

To investigate the efficacy and safety of dietary supplements for patients with osteoarthritis. An intervention systematic review with random effects meta-analysis and meta-regression. MEDLINE, EMBASE, Cochrane Register of Controlled Trials, Allied and Complementary Medicine and Cumulative Index to Nursing and Allied Health Literature were searched from inception to April 2017. Randomised controlled trials comparing oral supplements with placebo for hand, hip or knee osteoarthritis. Of 20 supplements investigated in 69 eligible studies, 7 (collagen hydrolysate, passion fruit peel extract, Curcuma longa extract, Boswellia serrata extract, curcumin, pycnogenol and L-carnitine) demonstrated large (effect size >0.80) and clinically important effects for pain reduction at short term. Another six (undenatured type II collagen, avocado soybean unsaponifiables, methylsulfonylmethane, diacerein, glucosamine and chondroitin) revealed statistically significant improvements on pain, but were of unclear clinical importance. Only green-lipped mussel extract and undenatured type II collagen had clinically important effects on pain at medium term. No supplements were identified with clinically important effects on pain reduction at long term. Similar results were found for physical function. Chondroitin demonstrated statistically significant, but not clinically important structural improvement (effect size -0.30, -0.42 to -0.17). There were no differences between supplements and placebo for safety outcomes, except for diacerein. The Grading of Recommendations Assessment, Development and Evaluation suggested a wide range of quality evidence from very low to high. The overall analysis including all trials showed that supplements provided moderate and clinically meaningful treatment effects on pain and function in patients with hand, hip or knee osteoarthritis at short term, although the quality of evidence was very low.

The technological and sensory quality of pasta made from bread wheat flour substituted with wholemeal amaranth flour (Amaranthus mantegazzianus) at four levels, 15, 30, 40 and 50% w/w was investigated. The quality of the resulted pasta was compared to that of control pasta made from bread wheat flour. The flours were analyzed for chemical composition and pasting properties. Cooking behavior, color, raw and cooked pasta texture, scanning electron microscopy and sensory evaluation were determined on samples. The pasta obtained from amaranth flour showed some detriment of the technological and sensory quality. So, a maximum substitution level of 30% w/w was defined. This is an equilibrium point between an acceptable pasta quality and the improved nutritional and functional properties from the incorporation of amaranth flour.

Full Text Available Background: In North America digestive malfunction in terms of disintegration, dissolution, and absorption of food and nutrients, is a widespread malady. Malabsorption is also an exacerbating factor in most chronic degenerative diseases that might benefit from dietary supplementation. The purpose of this experiment was to determine, as shown by changes in properties of live blood, whether, a novel soy-lecithin-phospholipid-nutrient encapsulation technology could promote rapid bioavailability and bioactivity of a VMP35 nutraceutical formulation encapsulated within its clustoidal multilamellar Soy Lecithin Phospholipid (SLP liquid SK713 SLP structures. Method: Changes in peripheral blood smears from 38 subjects were measured utilizing peripheral live blood cell imaging (LBCI with phase contrast microscopy. Results: Compared to baseline and control, consistently and reproducibly, the SK713 SLP technology effected positive changes in the blood as demonstrated by observable morphological, hematological and rheological changes five minutes from intake and sustained for at least 30 minutes post intake. Conclusions: These results showed that the SK713 SLP system makes an important contribution by increasing the potential benefits of dietary supplementation to those patients with compromised digestive processes. We encourage additional research on this novel delivery system believing that it has potential impact on future therapy.

Population-based screening for early detection and treatment of colorectal cancer (CRC) and precursor lesions, using evidence-based methods, can be effective in populations with a significant burden of the disease provided the services are of high quality. Multidisciplinary, evidence-based guidelines for quality assurance in CRC screening and diagnosis have been developed by experts in a project co-financed by the European Union. The 450-page guidelines were published in book format by the European Commission in 2010.They include 10 chapters and over 250 recommendations, individually graded according to the strength of the recommendation and the supporting evidence. Adoption of the recommendations can improve and maintain the quality and effectiveness of an entire screening process, including identification and invitation of the target population, diagnosis and management of the disease and appropriate surveillance in people with detected lesions. To make the principles, recommendations and standards in the guidelines known to a wider professional and scientific community and to facilitate their use in the scientific literature, the original content is presented in journal format in an open-access Supplement of Endoscopy. The editors have prepared the present overview to inform readers of the comprehensive scope and content of the guidelines. PMID:23212726

The dramatic rise in the use of smartphones, tablets, and laptop computers over the past decade has raised concerns about potentially deleterious health effects of increased "screen time" (ST) and associated short-wavelength (blue) light exposure. We determined baseline associations and effects of 6 months' supplementation with the macular carotenoids (MC) lutein, zeaxanthin, and mesozeaxanthin on the blue-absorbing macular pigment (MP) and measures of sleep quality, visual performance, and physical indicators of excessive ST. Forty-eight healthy young adults with at least 6 h of daily near-field ST exposure participated in this placebo-controlled trial. Visual performance measures included contrast sensitivity, critical flicker fusion, disability glare, and photostress recovery. Physical indicators of excessive screen time and sleep quality were assessed via questionnaire. MP optical density (MPOD) was assessed via heterochromatic flicker photometry. At baseline, MPOD was correlated significantly with all visual performance measures ( p eye strain, eye fatigue, and all visual performance measures, versus placebo ( p < 0.05 for all). Increased MPOD significantly improves visual performance and, in turn, improves several undesirable physical outcomes associated with excessive ST. The improvement in sleep quality was not directly related to increases in MPOD, and may be due to systemic reduction in oxidative stress and inflammation.

1. An experiment was performed to evaluate the effectiveness of the antioxidants curcumin (CRM) and lutein (LTN) on the quality of meat from coccidiosis-infected broilers. A total of 200 one-day-old Arbor Acre chicks were randomly assigned to a treatment group with 5 replicates. The treatments included a basal diet without carotenoid supplementation (control), with 300 mg/kg CRM, with 300 mg/kg LTN or with a combination (C + L) of 150 mg/kg CRM and 150 mg/kg LTN. All chickens were challenged with Eimeria maxima at 21 d old. 2. The results revealed that the coccidiosis reduced redness of meat, while supplementation with carotenoids improved the fresh meat's redness (a*) and yellowness (b*) and contributed to colour stability maintenance after storage (1 month at -18°C and 3 d at 4°C). 3. Coccidiosis did not produce lipid and protein oxidation in fresh meat, but after storage for one month, the malondialdehyde levels and carbonyl contents were lower in the CRM and C + L birds and the sulfhydryl contents were higher in C + L birds. 4. The sodium dodecyl sulphate-polyacrylamide gel electrophoresis banding pattern showed equivalent myosin chain fragmentations in all treatment groups, whereas lower intensity actin bands were observed in the control group (CONT). Moreover, myofibril protein denaturation (differential scanning calorimetry) profiles showed a reduction in the CONT myosin and actin peaks. Coccidiosis reduced the meat's water holding capacity in non-supplemented chicken meat and was improved by natural carotenoid. 5. These results emphasise that coccidiosis did not decrease the eating quality of fresh meat, that natural carotenoids are efficient antioxidants and that CRM (300 mg/kg) fed individually or combined with LTN was the most effective supplemented antioxidant compound.

The impact of cGMP compliance on consumer confidence in dietary supplement products
International Nuclear Information System (INIS)
Crowley, Richard; FitzGerald, Libby Harvey
2006-01-01
The FDA estimates that US citizens spend more than $ 8.5 billion a year on dietary supplements and world wide the market is estimated at more than $ 60 billion. However, although a majority of consumers express confidence in the safety of these products, 74% believe the government should be more involved in ensuring that these products are safe and efficacious. Recent regulatory initiatives such as the imminent adoption of cGMPs for dietary supplements in the US, implementation of cGMPs in Canada and the recent EU dietary supplement initiative represent legislative and industry response to public clamor for more comprehensive oversight of dietary supplements. Regardless of mandated practices, the majority of dietary supplement manufacturers have done an excellent job of protecting the safety and quality of their products. The promulgation of these cGMPs will help ensure consumers that equal standards are followed throughout the industry. For some companies with established processes based on existing food or pharmaceutical cGMP regulations, the transition will be relatively painless while, for many, it will represent a significant increase in the level of documentation and testing. However, consumers deserve and demand that products meet standards for safety and quality and the implementation of cGMPs for these products are an important first step. Although the cGMPs are designed to ensure products are safe from a standpoint of identity, purity, quality, strength and composition, they do not address preclinical or clinical testing of ingredients for safety or efficacy. This would involve ingredients meeting the requirements of Generally Recognized as Safe (GRAS) status or going through the New Dietary Ingredient (NDI) process

High-quality protein roughage is an important feed for productive ruminants. This study examined the effects of strategic feeding of lactating cows with cassava (Manihot esculenta) top silage (CTS) on rumen fermentation, feed intake, milk yield, and quality. Four early lactating crossbred dairy cows (75% Holstein-Friesian and 25% Thai) with body weight (BW) 410 ± 30 kg and milk yield 12 ± 2 kg/day were randomly allotted in a 4 × 4 Latin square design to four different supplementation levels of CTS namely, 0, 0.75, 1.50, and 2.25 kg/day of dry matter (DM). Strategic supplementation of CTS significantly affected ruminal fermentation end-products, especially increased propionate production, decreased protozoal population and suppressed methane production (P < 0.05). Increasing the CTS supplementation level substantially enhanced milk yield and the 3.5% FCM from 12.7 to 14.0 kg/day and from 14.6 to 17.2 kg/day (P < 0.05) for non-supplemented group and for the 2.25 kg/day supplemented group, respectively. We conclude that high-quality protein roughage significantly enhances rumen fermentation end-products, milk yield, and quality in dairy cows.

Full Text Available Abstract This study was intended to explore the effect of extruded flaxseed meal supplemented diet on broiler growth performance, oxidative stability and organoleptic characteristics of broiler meat and meat products. 120 (day old broiler chicks were randomly allotted to 12 experimental groups and fed on diets containing extruded flaxseed meal at 0, 5, 10 and 15%. The supplementation of extruded flaxseed in the diet decreases the body weight gain, feed intake and increased feed conversion ratio (FCR values of broilers. The antioxidant enzymes were strongly influenced by different levels of extruded flaxseed supplementation among treatments. The TBARS assay revealed that maximum malondialdehyde were produced in T3 containing highest extruded flaxseed level (15% and minimum malondialdehyde were produced in T0 treatment having no extruded flaxseed. The TBARS values ranged from 0.850-2.106 and 0.460-1.052 in leg and breast met respectively. The Free radical scavenging activity varied significantly and DPPH values of breast meat ranged from 20.70% to 39.09% and in leg meat 23.53% to 43.09% respectively. The sensory acceptability of broiler meat nuggets was decreased with the increase in the level of flaxseeds due to the lipid peroxidation of polyunsaturated fatty acids (PUFA which generated off flavors and bad odors. Feeding extruded flaxseed to chicken through feed strongly inflated the quality and functional properties, fatty acid contents and reduced the oxidative stability of broiler meat and meat products. The present study concludes that up to 10% of flaxseed meal may be used in broiler diet to enhance the omega 3 fatty acids content in the broiler meat.

The sensory acceptability of broiler meat nuggets was decreased with the increase in the level of flaxseeds due to the lipid peroxidation of polyunsaturated fatty acids (PUFA) which generated off flavors and bad odors. Feeding extruded flaxseed to chicken through feed strongly inflated the quality and functional properties, fatty acid contents and reduced the oxidative stability of broiler meat and meat products. The present study concludes that up to 10% of flaxseed meal may be used in broiler diet to enhance the omega 3 fatty acids content in the broiler meat.

Nutrition intervention aimed at preventing or reversing weight loss and wasting in HIV infection may help to improve quality of life and prolong survival. Micronutrient supplementation may help to strengthen the immune system and reduce the severity and impact of opportunistic infections in people living with HIV / AIDS. HIV contributes to malnutrition for physiological reasons related to the infection itself. HIV /AIDS, being a disease of the immune system, new strategies, including specific dietary nutrients (nutrient supplementation) to improve immune functions, quality of life and prolong survival in infected individuals, could provide additional/alternative approaches for therapeutic treatment in HIV infected subjects. Several vitamins and minerals are important in fighting HIV infection and its resultant effects, hence nutritional supplementation has been advocated. This review focuses on the importance of vitamin/mineral supplementation in HIV / AIDS subjects. (author)

Supplemental effect of varying L-cysteine concentrations on the quality of cryopreserved boar semen
Kaeoket, Kampon; Chanapiwat, Panida; Tummaruk, Padet; Techakumphu, Mongkol
2010-01-01
Cryopreservation is associated with the production of reactive oxygen species, which leads to lipid peroxidation of the sperm membrane and consequently a reduction in sperm motility and decreased fertility potential. The aim of this study was to determine the optimal concentration of L-cysteine needed for cryopreservation of boar semen. Twelve boars provided semen of proven motility and morphology for this study. The semen was divided into four portions in which the lactose-egg yolk (LEY) extender used to resuspend the centrifuged sperm pellet was supplemented with various concentrations of L-cysteine to reach 0 mmol L−1 (group I, control), 5 mmol L−1 (group II), 10 mmol L−1 (group III) and 15 mmol L−1 (group IV). Semen suspensions were loaded in straws (0.5 mL) and placed in a controlled-rate freezer. After cryopreservation, frozen semen samples were thawed and investigated for progressive motility, viability using SYBR-14/EthD-1 staining and acrosome integrity using FITC-PNA/EthD-1 staining. There was a significantly higher (P extender for improving the quality of frozen–thawed boar semen. PMID:20601963

Process Analytical Technology and On-Line Spectroscopic Measurements of Chemical Meat Quality
DEFF Research Database (Denmark)
Sørensen, Klavs Martin
This thesis deals with process analytical technology and how it can be implemented in the meat industry through on-line grading of chemical meat quality. The focus will be on two applications, namely the rapid quality control of fat quality and the development of a method for on-line detection...... of nano-molar quantification in few seconds, in addition to an accelerated extraction-free GC-MS method that through automation can deliver results much faster than other similar methods. The implementation of these high tech methods will provide the meat industry with a leading edge not only with product...... of boar taint. The chemical makeup of fat has a large effect on meat cut quality. Fat quality has traditionally been determined by methylation of a tissue sample followed by chromatography on a GC-MS system, elucidating the composition of the individual fatty acids.

The effects of health information technology on the costs and quality of medical care.
Agha, Leila
2014-03-01
Information technology has been linked to productivity growth in a wide variety of sectors, and health information technology (HIT) is a leading example of an innovation with the potential to transform industry-wide productivity. This paper analyzes the impact of health information technology (HIT) on the quality and intensity of medical care. Using Medicare claims data from 1998 to 2005, I estimate the effects of early investment in HIT by exploiting variation in hospitals' adoption statuses over time, analyzing 2.5 million inpatient admissions across 3900 hospitals. HIT is associated with a 1.3% increase in billed charges (p-value: 5.6%), and there is no evidence of cost savings even five years after adoption. Additionally, HIT adoption appears to have little impact on the quality of care, measured by patient mortality, adverse drug events, and readmission rates. Copyright © 2013 Elsevier B.V.

Complementarity in dietary supplements and foods: are supplement users vegetable eaters?
Kang, Hyoung-Goo; Joo, Hailey Hayeon; Choi, Kyong Duk; Lee, Dongmin; Moon, Junghoon
2017-01-01
Background : The consumption of fruits, vegetables, and dietary supplements correlate. Most previous studies have aimed to identify the determinants of supplement uses or the distinct features of supplement users; this literature lacks a discussion on dietary supplement consumption as a predictor of fruit and vegetable consumption. Objective : This study examines how dietary supplement consumption correlates with fruit and vegetable consumption by combining scanner data and surveys of Korean household grocery shopping. Methods : Propensity score matching (PSM) is used to identify the relationship between dietary supplement consumption and fruit and vegetable consumption in a household. A logit regression using supplement consumption as the dependent variable is used. Then, the supplement takers (the treatment group) are matched with non-takers (the control group) based on the propensity scores estimated in the logit regression. The fruit and vegetable consumption levels of the groups are then compared. Results : We found that dietary supplement use is associated with higher fruit and vegetable consumption. This supports the health consciousness hypothesis based on attention bias, availability heuristics, the focusing effect, and the consumption episode effect. It rejects the health substitute hypothesis based on economic substitutes and mental accounting. Conclusions : Future research on the health benefits of dietary supplements should address the complementary consumption of fruits/vegetables and their health benefits to avoid misstating the health effects of supplements.

mHealth apps are deployed with the aim of improving access, quality, and experience of health care. It is possible that any mHealth intervention can yield differential impacts for different types of users. Mediating and determining factors, including personal and socioeconomic factors, affect technology adoption, the way health workers leverage and use the technology, and subsequently the quality and experience of care they provide. To develop a framework to assess whether mHealth platforms affect the quality and experience of care provided by frontline workers, and whether these effects on quality and experience are different depending on the level of technology adoption and individual characteristics of the health worker. Literacy, education, age, and previous mobile experience are identified as individual factors that affect technology adoption and use, as well as factors that affect the quality and experience of care directly and via the technology. Formative research was conducted with 15 community health workers (CHWs) using CommCare, an mHealth app for maternal and newborn care, in Bihar, India. CHWs were first classified on the level of CommCare adoption using data from CommCareHQ and were then shadowed on home visits to evaluate their levels of technology proficiency, and the quality and experience of care provided. Regression techniques were employed to test the relationships. Out of all the CHWs, 2 of them refused to participate in the home visits, however, we did have information on their levels of technology adoption and background characteristics, which were included in the analysis as relevant. Level of technology adoption was important for both quality and experience of care. The quality score for high users of CommCare was higher by 33.4% (P=.04), on average, compared to low users of CommCare. Those who scored higher on CommCare proficiency also provided significantly higher quality and experience of care, where an additional point in Comm

Vitamin K supplementation for cystic fibrosis.
Jagannath, Vanitha A; Thaker, Vidhu; Chang, Anne B; Price, Amy I
2017-08-22
Cystic fibrosis is a genetic disorder which can lead to multiorgan dysfunction. Malabsorption of fat and fat-soluble vitamins (A, D, E, K) may occur and can cause subclinical deficiencies of some of these vitamins. Vitamin K is known to play an important role in both blood coagulation and bone formation. Supplementation with vitamin K appears to be one way of addressing the deficiency, but there is very limited agreement on the appropriate dose and frequency of use of these supplements. This is an updated version of the review. To assess the effects of vitamin K supplementation in people with cystic fibrosis and to determine the optimal dose and route of administration of vitamin K for both routine and therapeutic use. We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group's Trials Register comprising references identified from comprehensive electronic database searches and handsearches of relevant journals and abstract books of conference proceedings.Most recent search: 30 January 2017. Randomised and quasi-randomised controlled trials of all preparations of vitamin K used as a supplement compared to either no supplementation (or placebo) at any dose or route and for any duration, in children or adults diagnosed with cystic fibrosis (by sweat test or genetic testing). Two authors independently screened papers, extracted trial details and assessed their risk of bias. Two trials (total of 32 participants) each lasting one month were included in the review and were assessed as having a moderate risk of bias. One was a dose-ranging parallel group trial in children (aged 8 to 18 years); and the other (with an older cohort) had a cross-over design comparing supplements to no treatment, but no separate data were reported for the first intervention period. Neither of the trials addressed any of the primary outcomes (coagulation, bone formation and quality of life). Both trials reported the restoration of serum vitamin K and undercarboxylated osteocalcin

Rational and high-throughput optimization of mammalian cell culture media has a great potential to modulate recombinant protein product quality. We present a process design method based on parallel design-of-experiment (DoE) of CHO fed-batch cultures in 96-deepwell plates to modulate monoclonal antibody (mAb) glycosylation using medium supplements. To reduce the risk of losing valuable information in an intricate joint screening, 17 compounds were separated into five different groups, considering their mode of biological action. The concentration ranges of the medium supplements were defined according to information encountered in the literature and in-house experience. The screening experiments produced wide glycosylation pattern ranges. Multivariate analysis including principal component analysis and decision trees was used to select the best performing glycosylation modulators. Subsequent D-optimal quadratic design with four factors (three promising compounds and temperature shift) in shake tubes confirmed the outcome of the selection process and provided a solid basis for sequential process development at a larger scale. The glycosylation profile with respect to the specifications for biosimilarity was greatly improved in shake tube experiments: 75% of the conditions were equally close or closer to the specifications for biosimilarity than the best 25% in 96-deepwell plates.

Nuclear magnetic resonance (NMR) is a rapid, accurate and non-invasive technology and widely used to detect the quality of food, particularly to fruits and vegetables, meat and aquatic products. This review is a survey of recent developments in experimental results for the quality of food on various NMR technologies in processing and storage over the past decade. Following a discussion of the quality discrimination and classification of food, analysis of food compositions and detection of physical, chemical, structural and microbiological properties of food are outlined. Owing to high cost, low detection limit and sensitivity, the professional knowledge involved and the safety issues related to the maintenance of the magnetic field, so far the practical applications are limited to detect small range of food. In order to promote applications for a broader range of foods further research and development efforts are needed to overcome the limitations of NMR in the detection process. The needs and opportunities for future research and developments are outlined.

Application of quality function deployment in defense technology development
Cornejo, Estrella De Maria Forster
1998-12-01
Introduction. As advances in aviation technology take place, the research community recognizes, and the operator demands that the progress in technology be integrated with the human component of the same, the aircrew. Integrative programs are primarily concerned with three sub-systems: the operator, the aircraft, and the cockpit. To accomplish their integration, a "dialogue" between the various disciplines addressing these aspects of the weapon system is indispensable. Such dialogue is theorized to be possible via Quality Function Deployment (QFD). QFD emphasizes an understanding of the relationships between the requirements of the aircrew and the technology the research and engineering community provides. In establishing these relationships, program management concerns such as need, applicability, affordability, and transition of the technology are addressed. Procedures. QFD was incorporated in a Performance Methodology (PMM). This methodology associates a particular technology's Measures of Performance (MOP) and the overall weapon system's Measures of Effectiveness (MOE) to which it is applied. Incorporation of QFD in the PMM was hypothesized to result in an improved PMM (Q-PMM) that would address both, the aircrew's interests and those of program management. Both methodologies were performed. The g-ensemble was selected as the technology of interest. The Standard and Combat Edge designs were examined for comparison purposes. Technology MOPs were ranked in order of importance in accordance to both the PMM and its proposed improvement, the Q-PMM. These methodologies were then evaluated by way of an experiment in the human centrifuge. This experiment was to answer two questions: Is there a relationship between the technology's MOP and the aircraft's MOEs? Given a MOP-MOE relationship, is there a difference between the two ensembles? Findings. The Q-PMM was superior to the PMM in addressing customer's requirements. The Q-PMM was superior to the PMM in addressing

How to Achieve High-Quality Oocytes? The Key Role of Myo-Inositol and Melatonin
Directory of Open Access Journals (Sweden)
Salvatore Giovanni Vitale
2016-01-01
Full Text Available Assisted reproductive technologies (ART have experienced growing interest from infertile patients seeking to become pregnant. The quality of oocytes plays a pivotal role in determining ART outcomes. Although many authors have studied how supplementation therapy may affect this important parameter for both in vivo and in vitro models, data are not yet robust enough to support firm conclusions. Regarding this last point, in this review our objective has been to evaluate the state of the art regarding supplementation with melatonin and myo-inositol in order to improve oocyte quality during ART. On the one hand, the antioxidant effect of melatonin is well known as being useful during ovulation and oocyte incubation, two occasions with a high level of oxidative stress. On the other hand, myo-inositol is important in cellular structure and in cellular signaling pathways. Our analysis suggests that the use of these two molecules may significantly improve the quality of oocytes and the quality of embryos: melatonin seems to raise the fertilization rate, and myo-inositol improves the pregnancy rate, although all published studies do not fully agree with these conclusions. However, previous studies have demonstrated that cotreatment improves these results compared with melatonin alone or myo-inositol alone. We recommend that further studies be performed in order to confirm these positive outcomes in routine ART treatment.

Demin Mirjana A.
2013-01-01
Full Text Available The aim of this work was to compare the nutritional characteristics of wheat bread with the bread produced of wheat flour supplemented with quinoa and buckwheat seeds. Bread making properties of these blends were analyzed in order to investigate their ability to make moulded bread. Quinoa (Chenopodium quinoa Will. and buckwheat seeds were grown in the vicinity of Belgrade, Serbia. The addition of pseudocereal seeds (at levels of 30% and 40% and a selected technological process, which included hydrothermal preparation of supplements, resulted with a valuable effect on nutritive value of breads. In comparison with the wheat bread that was used as control sample, the protein increase of 2% and the increase of crude fiber content at around 0.5% in 30% supplemented breads were registered. Furthermore, the incorporation of both seeds mixture at the level of 40%, increased the content of protein for 2.5% and fiber content for 0.4%. In regard to the starch, fat, and ash contents there were no major differences. The investigated breads were nutritionally superior to the wheat bread. Chemical composition of the selected seeds was also investigated. The results showed that the blends containing either 30% or 40% of selected seeds expressed high potential for the production of molded breads, as new baking products with enhanced nutritional composition. The applied technological procedure was modified in such way that for all blended combination of supplements it changed rheological properties of dough. Furthermore, it resulted in a good volume of breads with excellent sensory properties of aroma-odor and taste.

Physician use of clinical information technology (CIT) is important for the management of chronic illness, but has lagged behind expectations. We studied the role of health insurers' financial incentives (including pay-for-performance) and quality improvement initiatives in accelerating adoption of CIT in large physician practices. National survey of all medical groups and independent practice association (IPA) physician organizations with 20 or more physicians in the United States in 2006 to 2007. The response rate was 60.3%. Use of 19 CIT capabilities was measured. Multivariate statistical analysis of financial and organizational factors associated with adoption and use of CIT. Use of information technology varied across physician organizations, including electronic access to laboratory test results (medical groups, 49.3%; IPAs, 19.6%), alerts for potential drug interactions (medical groups, 33.9%; IPAs, 9.5%), electronic drug prescribing (medical groups, 41.9%; IPAs, 25.1%), and physician use of e-mail with patients (medical groups, 34.2%; IPAs, 29.1%). Adoption of CIT was stronger for physician organizations evaluated by external entities for pay-for-performance and public reporting purposes (P = 0.042) and for those participating in quality improvement initiatives (P < 0.001). External incentives and participation in quality improvement initiatives are associated with greater use of CIT by large physician practices.

Romanian Government Decision (GD) No. 8/2012 amending and supplementing GD No. 144/2010 regarding the function and organization structures of the Ministry of Health defines health technology assessment (HTA) as "a systematic and multidisciplinary analysis of the existing and new medical technologies, through which medical, economic, social, ethical and organizational information are synthesized so that medical technologies to be used in a transparent and unbiased manner". We propose an ethical assessment model of technologies used in the care of diabetic patients. The nature of this research was exploratory, giving the novelty of this approach to the clinical and social context of Romania. The assessment of health technologies used in the care of diabetic patients was based on the following research question: What is the role of health technology in developing autonomy and responsibility in patients suffering from chronic diseases? Individual interviews and focus groups were held from June, 2011 to November, 2012 in Iasi. The criterion for selecting the participants was belonging to the target groups: family doctors or diabetes specialist, patients with type 1 (TID) and type 2 diabetes (T2D), caregivers and other professionals involved in diabetes patient care. The diabetic patient benefits from a specific treatment and has the privilege of self-administering it, his life expectancy and quality of life depending upon the compliance and responsibility he demonstrates.

Oral protein calorie supplementation for children with chronic disease
Francis, Damian K; Smith, Joanne; Saljuqi, Tawab; Watling, Ruth M
2015-01-01
Background Poor growth and nutritional status are common in children with chronic diseases. Oral protein calorie supplements are used to improve nutritional status in these children. These expensive products may be associated with some adverse effects, e.g. the development of inappropriate eating behaviour patterns. This is a new update of a Cochrane review last updated in 2009. Objectives To examine evidence that in children with chronic disease, oral protein calorie supplements alter daily nutrient intake, nutritional indices, survival and quality of life and are associated with adverse effects, e.g. diarrhoea, vomiting, reduced appetite, glucose intolerance, bloating and eating behaviour problems. Search methods Trials of oral protein calorie supplements in children with chronic diseases were identified through comprehensive electronic database searches, handsearching relevant journals and abstract books of conference proceedings. Companies marketing these products were also contacted. Most recent search of the Group's Trials Register: 24 February 2015. Selection criteria Randomised or quasi-randomised controlled trials comparing oral protein calorie supplements for at least one month to increase calorie intake with existing conventional therapy (including advice on improving nutritional intake from food or no specific intervention) in children with chronic disease. Data collection and analysis We independently assessed the outcomes: indices of nutrition and growth; anthropometric measures of body composition; calorie and nutrient intake (total from oral protein calorie supplements and food); eating behaviour; compliance; quality of life; specific adverse effects; disease severity scores; and mortality; we also assessed the risk of bias in the included trials. Main results Four studies (187 children) met the inclusion criteria. Three studies were carried out in children with cystic fibrosis and one study included children with paediatric malignant disease

Full Text Available A consumer survey on dietary supplement consumption was carried out on 494 consumers aged 20 years and older in Chiang Mai province. The percentage of consumers who regularly consumed dietary supplements was 38.5%. Vitamins and minerals were the most consumed products, followed by functional drinks, functional foods, protein extracts, dietary fibre, cod liver oil, phytochemicals, algae products, fat absorbers, fish oils and bee products in that order. Females and participants who had recommended waistlines, had higher income, usually felt stressed or sick, and who preferred eating fruits/vegetables or routinely drank water tended to have a higher rate of consumption of dietary supplements. Participants gave priority over a product with guaranteed quality when they made decision to purchase dietary supplements, but their purchase was also influenced by the attractiveness of the product and advertisement for it.

The improvement of quality traits in food and industrial crops is an important breeding objective for both developed and developing countries in order to add value to the crop and thereby increasing farmers' income. It has been well established that the application of mutagens can be a very important approach for manipulating many crop characteristics including quality. While mutation induction using nuclear techniques such as gamma irradiation is a power tool in generating new genotypes with favourable alleles for improving crop quality in plant breeding, a more thorough understanding of gene expression, gene interactions, and physical location will improve ability to manipulate and control genes, and directly lead to crop improvement. Physical mapping technologies, molecular markers and molecular cytogenetic techniques are tools available with the potential to enhance the ability to tag genes and gene complexes to facilitate the selection of desirable genotypes in breeding programmes, including those based on mutation breeding. This Coordinated Research Project (CRP) on 'Physical Mapping Technologies for the Identification and Characterization of Mutated Genes Contributing to Crop Quality' was conducted under the overall IAEA project objective of 'Identification, Characterization and Transfer of Mutated Genes'. The specific objectives of the CRP were to assist Member States in accelerating crop breeding programmes through the application of physical mapping and complementary genomic approaches, and the characterization and utilization of induced mutants for improvement of crop quality. The IAEA-TECDOC describes the success obtained in the application of molecular cytology, molecular markers, physical mapping and mutation technologies since the inception of the CRP in 2003. The CRP also resulted in two book chapters, 35 peer reviewed papers, 25 conference proceedings, one PhD thesis, and 22 published abstracts. In addition, thirteen sequences were submitted to the

Barriers and enablers for iron folic acid (IFA) supplementation in pregnant women.
Siekmans, Kendra; Roche, Marion; Kung'u, Jacqueline K; Desrochers, Rachelle E; De-Regil, Luz Maria
2017-12-22
In order to inform large scale supplementation programme design, we review and summarize the barriers and enablers for improved coverage and utilization of iron and folic acid (IFA) supplements by pregnant women in 7 countries in Africa and Asia. Mixed methods were used to analyse IFA supplementation programmes in Afghanistan, Bangladesh, Indonesia, Ethiopia, Kenya, Nigeria, and Senegal based on formative research conducted in 2012-2013. Qualitative data from focus-group discussions and interviews with women and service providers were used for content analysis to elicit common themes on barriers and enablers at internal, external, and relational levels. Anaemia symptoms in pregnancy are well known among women and health care providers in all countries, yet many women do not feel personally at risk. Broad awareness and increased coverage of facility-based antenatal care (ANC) make it an efficient delivery channel for IFA; however, first trimester access to IFA is hindered by beliefs about when to first attend ANC and preferences for disclosing pregnancy status. Variable access and poor quality ANC services, including insufficient IFA supplies and inadequate counselling to encourage consumption, are barriers to both coverage and adherence. Community-based delivery of IFA and referral to ANC provides earlier and more frequent access and opportunities for follow-up. Improving ANC access and quality is needed to facilitate IFA supplementation during pregnancy. Community-based delivery and counselling can address problems of timely and continuous access to supplements. Renewed investment in training for service providers and effective behaviour change designs are urgently needed to achieve the desired impact. © 2018 John Wiley & Sons Ltd.

Sixty-four pairs of oxen owned by smallholders were randomly allocated to one of 3 supplementary treatments offered at one kg per head per day from July to October or to a control where no supplement was offered. The supplements were maize stover plus silverleaf hay (2:1 w/w), urea-treated maize stover (50 g urea/kg stover) and plain maize stover. Animals fed plain maize stover or no supplement lost weight (6 to 7% of initial weight), whilst those fed the other 2 supplements maintained their liveweights. Supplementation reduced time spent on feeding activities by 10 per cent. Animals fed on urea-treated maize stover or maize stover plus silverleaf hay ploughed at speeds that were 29% faster than oxen on the other treatments and covered 45% more area. Blood parameters indicated a general deficiency of nitrogen intake throughout the dry season. It was concluded that supplements of good quality have the potential to improve the working ability of communal area oxen.

Selenium supplementation for Hashimoto's thyroiditis.
van Zuuren, Esther J; Albusta, Amira Y; Fedorowicz, Zbys; Carter, Ben; Pijl, Hanno
2013-06-06
Hashimoto's thyroiditis is a common auto-immune disorder. The most common presenting symptoms may include anxiety, negative mood, depression, dry skin, cold intolerance, puffy eyes, muscle cramps and fatigue, deep voice, constipation, slow thinking and poor memory. Clinical manifestations of the disease are defined primarily by low levels of thyroid hormones; therefore it is treated by hormone replacement therapy, which usually consists of levothyroxine (LT4). Selenium might reduce antibody levels and result in a decreased dosage of LT4 and may provide other beneficial effects (e.g. on mood and health-related quality of life). To assess the effects of selenium supplementation on Hashimoto's thyroiditis. We searched the following databases up to 2 October 2012: CENTRAL in The Cochrane Library (2012, Issue 10), MEDLINE, EMBASE, and Web of Science; we also screened reference lists of included studies and searched several online trial registries for ongoing trials (5 November 2012). Randomised controlled clinical trials that assessed the effects of selenium supplementation for adults diagnosed with Hashimoto's thyroiditis. Study selection, data extraction, assessment of risk of bias, and analyses were carried out by two independent review authors. We assessed the quality of the evidence of included studies using GRADE. We were unable to conduct a meta-analysis because clinical heterogeneity between interventions that were investigated is substantial. Four studies at unclear to high risk of bias comprising 463 participants were included. The mean study duration was 7.5 months (range 3 to 18 months). One of our primary outcomes－'change from baseline in health related quality of life'－and two of our secondary outcomes－'change from baseline in LT4 replacement dosage at end of the study' and 'economic costs'－were not assessed in any of the studies. One study at high risk of bias showed statistically significant improvement in subjective well-being with sodium

Our objective was to determine the effects of peridialytic oral supplements on nutritional markers and quality of life (QOL) in patients receiving maintenance hemodialysis. This trial was open, prospective, nonrandomized, and comparative. This study was performed at an outpatient hemodialysis unit in a teaching hospital. This study included 88 adults with chronic kidney disease at stage 5. This study involved directly observed nutrition therapy with >or=1 can of enteral nutrition (Nepro) with each hemodialysis session thrice weekly for 3 months, or standard care. Changes in biochemical markers of nutritional status and QOL, as measured by the Kidney Disease Quality of Life-Short Form, were determined. Peridialytic oral nutrition resulted in a significant difference between the nutrition and comparison groups in serum albumin change over time (P = .03; repeated-measures analysis of variance with covariates). Mean (+/-SD) serum albumin concentration did not differ between baseline and month 3 in the nutrition group (3.68 +/- 0.33 g/dL vs. 3.75 +/- 0.40 g/dL; P = .12), but in the comparison group, serum albumin levels declined significantly (3.93 +/- 0.34 g/dL at baseline versus 3.81 +/- 0.37 g/dL at month 3; P = .04). The "role-physical" domain score of the Kidney Disease Quality of Life-Short Form significantly changed over time in the nutrition group versus the comparison group (P = .02; repeated-measures analysis of variance with covariates). Nepro was well-tolerated, and greater than 80% of the prescribed therapy was consumed. Oral nutrition, as part of structured, directly observed peridialytic therapy in chronic hemodialysis patients, was well-accepted, and resulted in the maintenance of serum albumin levels and QOL with respect to impact of physical health on daily activities. These findings need to be confirmed in a randomized, controlled trial.

Dietary supplements for body-weight reduction: a systematic review.
Pittler, Max H; Ernst, Edzard
2004-04-01
Compliance with conventional weight-management programs is notoriously poor, and a plethora of over-the-counter slimming aids are sold with claims of effectiveness. The objective of the study was to assess the evidence from rigorous clinical trials, systematic reviews, and meta-analyses on the effectiveness of dietary supplements in reducing body weight. The study was a systematic review. Literature searches were conducted on Medline, Embase, Amed, Cinahl, and the Cochrane Library until March 2003. Hand searches of medical journals, the authors' own files, and bibliographies of identified articles were conducted. There were no restrictions regarding the language of publication. The screening of studies, selection, validation, data extraction, and the assessment of methodologic quality were performed independently by the 2 reviewers. To be included, trials were required to be randomized and double-blind. Systematic reviews and meta-analyses of dietary supplements were included if they were based on the results of randomized, double-blind trials. Five systematic reviews and meta-analyses and 25 additional trials were included and reviewed. Data on the following dietary supplements were identified: chitosan, chromium picolinate, Ephedra sinica, Garcinia cambogia, glucomannan, guar gum, hydroxy-methylbutyrate, plantago psyllium, pyruvate, yerba maté, and yohimbe. The reviewed studies provide some encouraging data but no evidence beyond a reasonable doubt that any specific dietary supplement is effective for reducing body weight. The only exceptions are E. sinica- and ephedrine-containing supplements, which have been associated with an increased risk of adverse events. The evidence for most dietary supplements as aids in reducing body weight is not convincing. None of the reviewed dietary supplements can be recommended for over-the-counter use.

The aim of this study was to investigate how dietary supplementation of tea polyphenols (TP) and tea catechins (TC) affect laying performance, albumen quality, ovomucin composition, and magnum morphology of laying hens in the late phase of production. Two hundred seventy Hy-Line Brown laying hens (64 wk old) were assigned to a basal diet (the control), the basal diet supplemented with 200 mg/kg tea polyphenols (TP200) or 200 mg/kg tea catechins (TC200). Each treatment had 6 replicates with 15 hens each. The feeding trial lasted 10 wks. Over the course of the trial, dietary supplementation with TP200 significantly increased the egg production (EP) and improved the feed conversion ratio (FCR) in wk 6 to 10 and wk 1 to 10 (P hens fed TP200 were higher than those of hens fed the control diet at wks 8 and 10 (P 0.05). The SDS-PAGE analysis indicated that bands of the ovomucin fractions in the TP200 group had the highest intensity compared with those of the control and TC200 groups. Compared with the control, there was a significant increase in protein sulfhydryl (SH) content of the albumen in the TP200 group at the end of experiment, while a significant decrease in protein carbonyl content and protein surface hydrophobicity (P hens. In addition, TP rather than TC could improve the health status of the magnum for aged layers.

Fatty acid analysis of periphyton is an emerging tool for assessing the condition of a stream ecosystem on the basis of its water quality. The study presented in this report was designed to test the hypothesis that periphyton communities have a fatty acid profile that can detect excessive turbidity and suspended sediment. The fatty acid composition of periphyton was assessed during two seasons upstream and downstream from an underground aqueduct that provides supplemental flows, which are a potential source of turbidity and suspended sediment on the upper Esopus Creek, New York. These data were compared with measurements of periphyton standing crop, diatom community structure and integrity, and basic water-quality parameters. Periphyton standing crop and diatom community integrity indicated little evidence of impairment from the supplemental flows. The relative abundances of two physiologically important fatty acids, γ-linolenic acid (18:3ω6) and eicosapentaenoic acid (20:5ω3), were significantly lower downstream from the supplemental flows and multivariate analyses of fatty acid profiles identified significant differences between sites upstream and downstream from the supplemental flows. Individual fatty acids and summary metrics, however, were not significantly correlated with turbidity or suspended sediment. Together, these results indicate that the supplemental flows may cause some measurable effects but they do not constitute a major disturbance to the periphyton community on the upper Esopus Creek. Fatty acid analysis may have potential as a tool for monitoring changes in periphyton nutritional composition that may reflect water quality and ecosystem health but needs to be further evaluated around a more definitive source of water-quality impairment.

Regents College, created by the Board of Regents of the University of The State on New York in 1971, has been offering, since January 1985, AS and BS degrees in nuclear technology. The impetus for establishing the nuclear technology degrees came from nuclear utility management and had to do with the US Nuclear Regulatory Commission proposed rule regarding degreed operators on shift. There are a variety of ways to earn credits in Regents College degree programs: (1) college courses taken for degree-level credit from regionally accredited colleges; (2) courses sponsored by business, industry, or government that have been evaluated and recommended for credit by the New York National or American Council on Education (ACE's) Program on Noncollegiate Sponsored Instruction (PONSI); (3) military education that has been evaluated by ACE PONSI; (4) approved college-proficiency examinations; and (5) special assessment: an individualized examination of college-level knowledge gained from experience or independent study. Nuclear technology students primarily use college course work, evaluated military education, and proficiency examinations to complete degree programs. However, an increasing number of utilities are having training programs PONSI evaluated, resulting in an increased use of these courses in the nuclear technology degrees. Quality control is a function of several factors described in the paper

Full Text Available Background: antioxidants supplementation improves sperm quality, but few trials have analyzed the effects on sperm DNA fragmentation (SDF. This study compares the effectiveness of SOD-based antioxidant supplementation plus hydroxytyrosol and carnosol in reducing SDF with other antioxidants without SOD, hydroxytyrosol, and carnosol. Materials and methods: men with high SDF at baseline were selected in our clinical database. The patients taken into account had a 2-month control. SDF was measured by Sperm Chromatin Dispersion test (SCD. Untreated men were used as a control group. The remaining subjects received some oral antioxidant supplements (12 different combinations of both hydrophilic and lipophilic antioxidants, with some of them receiving nutritional support with a SOD-based antioxidant supplementation plus hydroxytyrosol and carnosol. Results: 118 men were selected for a retrospective study. Mean age 39.3 ± 5.4 years. Fifteen had no treatment, 55 were treated with a SOD-based antioxidant supplementation plus hydroxytyrosol and carnosol, and 48 took some antioxidant supplements for 2 months. Clinically, variations of at least 10% in baseline values of classic semen parameters and sperm DNA fragmentation were taken into consideration. Classic seminal parameters did not vary significantly in the three groups, with the exception of viability (p = 0.001. We assessed which of the active substances (no. 19 in different formulations were associated with variations in SDF. In the multivariable analysis of the 7 active substances that passed the univariable analysis, only the SOD molecule appeared to be linked to an improvement in SDF (< 0.0001. In detail, only one patient in the control group showed a spontaneous improvement in SDF (6%, compared to 16/48 (33% of those taking various oral antioxidant supplements, and 31/55 (56% of those taking a SOD-based antioxidant supplementation plus hydroxytyrosol and carnosol.

interference of the forage availability and quality and level of supplementation on performance. The total DM and green dry matter pasture availability deferred for use in the dry season has an average of all experiments of 6,431 kg ha-1 and 2,173 kg ha-1. The Brachiaria under grazing in the dry season have high levels of NDF, with an average of 74.50%, high levels of ADF, with an average of 44.19%, low levels of CP, with average of 5.59% and low levels of IVDM/O, with an average of 51.36%. In this sense, the diet taken by the animal usually presents higher crude protein and lower levels of NDF. On consumption in grazing, note that the intake reduction is limited by until the level of supplementation of 0.3% of body weight (BW per day and when the consumption of supplement increases to levels above 0.3% of BW, the consumption of grass is low and that this decrease may be even greater when the supply of supplement is 0.8% of the BW. Supplementation of cattle provided larger gains than those receiving only mineral in the dry season. Must be guaranteed at least 4,500 kg DM total.ha-1, 1,200 kg.ha-1 of green dry matter, offering 10 to 12% of the BW offorage DM and 6% of DM potentially digestible to ensure selectivity and earnings satisfactory individual without compromising the gain per area. A supplementation in the dry season in Brachiaria is biologically feasible for positive effect on weight gain, but the economic viability of the system is location dependent. Supplementation levels above 0.8% of the BW should be investigated as alternatives that may avoid possible negative effects on the rumen environment to reduce the expectations of gain, as the fractionation of supplementation.

Monitoring and surveillance for multiple micronutrient supplements in pregnancy.
Mei, Zuguo; Jefferds, Maria Elena; Namaste, Sorrel; Suchdev, Parminder S; Flores-Ayala, Rafael C
2017-12-22
The World Health Organization (WHO) recommends iron-folic acid (IFA) supplementation during pregnancy to improve maternal and infant health outcomes. Multiple micronutrient (MMN) supplementation in pregnancy has been implemented in select countries and emerging evidence suggests that MMN supplementation in pregnancy may provide additional benefits compared to IFA alone. In 2015, WHO, the United Nations Children's Fund (UNICEF), and the Micronutrient Initiative held a "Technical Consultation on MMN supplements in pregnancy: implementation considerations for successful incorporation into existing programmemes," which included a call for indicators needed for monitoring, evaluation, and surveillance of MMN supplementation programmes. Currently, global surveillance and monitoring data show that overall IFA supplementation programmes suffer from low coverage and intake adherence, despite inclusion in national policies. Common barriers that limit the effectiveness of IFA-which also apply to MMN programmes-include weak supply chains, low access to antenatal care services, low-quality behaviour change interventions to support and motivate women, and weak or non-existent monitoring systems used for programme improvement. The causes of these barriers in a given country need careful review to resolve them. As countries heighten their focus on supplementation during pregnancy, or if they decide to initiate or transition into MMN supplementation, a priority is to identify key monitoring indicators to address these issues and support effective programmes. National and global monitoring and surveillance data on IFA supplementation during pregnancy are primarily derived from cross-sectional surveys and, on a more routine basis, through health and logistics management information systems. Indicators for IFA supplementation exist; however, the new indicators for MMN supplementation need to be incorporated. We reviewed practice-based evidence, guided by the WHO/Centers for Disease

Full Text Available Milk quality is affected by feed nutrient either macronutrient or micronutrient. Roasted soayabeans and calcium soap were to increase supply by pas protein and fat to dairy cattle. Thus, organic mineral was to increase bioavailability of feed mineral to animal. The objective of this study was to evaluate roasted soybean, mineral soap and organic mineral supplementation on milk quality of dairy cattle. Twenty lactating Frisian Holstein cows (initial weight 361.4 ± 40.39 kg were assigned into a randomized complete block design with 5 treatments and 4 blocks. The treatments were A: basal diet, B: A + roasted soybean, C: B + calcium soap of corn oil, D: C + calcium soap of corn oil, E: C + calcium soap of fish oil. The experimental diets were offered for 9 and 2 weeks preliminary. The results of the experiment showed that milk protein and lactose were not affected by diets. Milk dry matter of cows fed A, B, and D diets were higher (P<0.05 than those of fed C and E diets. Milk fat of cows fed A, B and D diets were higher (P<0.05 than those of fed C and E diets. Milk density of cows fed B and E diets were higher (p<0.05 than those of fed A, C and D diets. Milk TPC of cows fed B diet were higher (0.05 than those of fed A, C, D, and E diets. It is concluded that milk quality especially milk protein and lactose concentration are not affected by roasted soyabeans, Ca-soap, and organic mineral. Calcium soap of fish oil and organic mineral decrease population of milk bacteria.

Stallion semen is damaged by oxidative stress during cooling and transport. Semen processing and extenders have been tested to improve the fertilizing capacity of semen and to preserve semen during transport. Dietary supplementation with natural antioxidants has been proposed to prevent oxidative damages. In this study, for the first time, the effect of dietary supplementation with Lepidium meyenii (Maca) on the characteristics of fresh and chilled stallion semen was evaluated. Maca is a traditional Andean crop used as a nutraceutical for the fertility-enhancing properties that are linked with antioxidant activity. The diet of five stallions was supplemented with 20 g of Maca powder daily for a total of 60 days. A control group of five stallions received the same diet without Maca. Semen was collected once before the administration of Maca (D0), twice during the administration at 30 and 60 days (D30 and D60), and finally twice at 30 and 60 days after the end of the administration (D90 and D120). Ejaculates were processed for cooled shipping at 5 °C and evaluated in the laboratory for total and progressive motility, acrosome integrity, and lipid peroxidation after collection and after 24, 48, and 72 h of storage. Dietary supplementation with Maca improved sperm concentration (from 213 ± 80.4 to 447 ± 73.1 × 10 6 spz/mL) and total sperm count (from 10,880 ± 4377 to 24,783 ± 4419 × 10 6 spz). The beneficial effects of Maca supplementation on motility and acrosome integrity in the raw semen were detected from the end of treatment with Maca (D60) until the end of the study (D120). Furthermore, during cooling storage, total motility, progressive motility, and acrosome integrity declined more slowly in the Maca-treated group than in the control group. Lipid peroxidation did not change during cooling storage in either group and did not show a significant difference between the two groups. In this study, the dietary supplementation with Maca

Dietary supplements: What's in a name? What's in the bottle?
Marcus, Donald M
2016-01-01
The Dietary Supplement Health and Education Act of 1994 (DSHEA), which arbitrarily classified herbals and other medicinal products as dietary supplements, obscured fundamental differences between two classes of products. Authentic supplements to the diet, such as multivitamins or calcium, have nutritional value and are safe. Herbals are used worldwide as medicines, they do not supplement the diet, they may cause severe adverse events, and they should be regulated as medicines. DSHEA also prevented the Food and Drug Administration (FDA) from effectively regulating herbal supplements as medicines. One consequence of weak FDA regulatory oversight is the poor quality of herbals. FDA inspections of manufacturing facilities have revealed violations of good manufacturing practices in over half of facilities inspected, including unsanitary conditions and lack of product specifications. Moreover, many "all natural" herbals marketed for weight loss, enhancement of sexual health and improving sports performance are adulterated with prescription and over-the-counter medications that have caused adverse cardiovascular events. New procedures to authenticate the identity of plants used in herbals will neither detect adulteration by medications nor provide assurance of appropriate pharmacological activity or safety. Nonvitamin, nonmineral "supplements" should be regulated as medicines, but revision or repeal of DSHEA faces strong opposition in Congress. The marketing of botanical supplements is based on unfounded claims that they are safe and effective. Health professionals need to inform patients and the public that there is no reason to take herbal medicines whose composition and benefits are unknown, and whose risks are evident.

We sought to define quality in telehealth and telecare with the aim of improving the proportion of patients who receive appropriate, acceptable and workable technologies and services to support them living with illness or disability. This was a three-phase study: (1) interviews with seven technology suppliers and 14 service providers, (2) ethnographic case studies of 40 people, 60 to 98 years old, with multi-morbidity and assisted living needs and (3) 10 co-design workshops. In phase 1, we explored barriers to uptake of telehealth and telecare. In phase 2, we used ethnographic methods to build a detailed picture of participants' lives, illness experiences and technology use. In phase 3, we brought users and their carers together with suppliers and providers to derive quality principles for assistive technology products and services. Interviews identified practical, material and organisational barriers to smooth introduction and continued support of assistive technologies. The experience of multi-morbidity was characterised by multiple, mutually reinforcing and inexorably worsening impairments, producing diverse and unique care challenges. Participants and their carers managed these pragmatically, obtaining technologies and adapting the home. Installed technologies were rarely fit for purpose. Support services for technologies made high (and sometimes oppressive) demands on users. Six principles emerged from the workshops. Quality telehealth or telecare is 1) ANCHORED in a shared understanding of what matters to the user; 2) REALISTIC about the natural history of illness; 3) CO-CREATIVE, evolving and adapting solutions with users; 4) HUMAN, supported through interpersonal relationships and social networks; 5) INTEGRATED, through attention to mutual awareness and knowledge sharing; 6) EVALUATED to drive system learning. Technological advances are important, but must be underpinned by industry and service providers following a user-centred approach to design and

Can data collectors be “pushed” into collecting high quality data or would being “pulled” be more effective? This paper finds that managers should be careful of the degree to which “push” factors, such as managerial pressure and technological input control, are relied upon. While they may be helpful for motivating those data collectors who are not intrinsically motivated, they are either not helpful or may discourage those data collectors who are intrinsically motivated. Instead, self-concordance may act as a longer-term, more stable approach to increasing the motivation of data collectors and thus increasing the quality of data that enter reliability systems. This study uses a sequential mixed-method approach involving interviews with 20 data collectors and a quantitative survey of 109 data collectors in a water utility. It examines the interactive effect of managerial pressure, technological input control and self-concordance on data collection performance

Full Text Available Abstract Background It remains unclear whether estrogenic botanical supplement (EBS use influences breast cancer survivors' health-related outcomes. Methods We examined the associations of EBS use with health-related quality of life (HRQOL, with fatigue, and with 15 hormone-related symptoms such as hot flashes and night sweats among 767 breast cancer survivors participating in the Health, Eating, Activity, and Lifestyle (HEAL Study. HRQOL was measured by the Medical Outcomes Study short form-36 physical and mental component scale summary score. Fatigue was measured by the Revised-Piper Fatigue Scale score. Results Neither overall EBS use nor the number of EBS types used was associated with HRQOL, fatigue, or hormone-related symptoms. However, comparisons of those using each specific type of EBS with non-EBS users revealed the following associations. Soy supplements users were more likely to have a better physical health summary score (odds ratio [OR] = 1.66, 95% confidence interval [CI] = 1.02-2.70. Flaxseed oil users were more likely to have a better mental health summary score (OR = 1.76, 95% CI = 1.05-2.94. Ginseng users were more likely to report severe fatigue and several hormone-related symptoms (all ORs ≥ 1.7 and all 95% CIs exclude 1. Red clover users were less likely to report weight gain, night sweats, and difficulty concentrating (all OR approximately 0.4 and all 95% CIs exclude 1. Alfalfa users were less likely to experience sleep interruption (OR = 0.28, 95% CI = 0.12-0.68. Dehydroepiandrosterone users were less likely to have hot flashes (OR = 0.33, 95% CI = 0.14-0.82. Conclusions Our findings indicate that several specific types of EBS might have important influences on a woman's various aspects of quality of life, but further verification is necessary.

Par-baked Bread Technology: Formulation and Process Studies to Improve Quality.
Almeida, Eveline Lopes; Steel, Caroline Joy; Chang, Yoon Kil
2016-01-01
Extending the shelf-life of bakery products has been an important requirement resulting from the mechanization of this industry and the need to increase the distance for the distribution of final products, caused by the increase in production and consumer demand. Technologies based on the interruption of the breadmaking process represent an alternative to overcome product staling and microbiological deterioration. The production of par-baked breads is one of these technologies. It consists of baking the bread in two stages, and due to the possibility of retarding the second stage, it can be said that the bread can always be offered fresh to the consumer. The technology inserts logistics as part of the production process and creates the "hot point" concept, these being the locations where the bread is finalized, such as in the consumers' homes or sales locations. In this work, a review of the papers published on this subject was carried out, and aspects related to both the formulation and the process were considered. This technology still faces a few challenges, such as solving bread quality problems that appear due to process modifications, and these will also be considered. The market for these breads has grown rapidly and the bakery industry searches innovations related to par-baked bread technology.

Spirulina as a livestock supplement and animal feed.
Holman, B W B; Malau-Aduli, A E O
2013-08-01
Spirulina (Athrospira sp.) is an edible microalga and a highly nutritious potential feed resource for many agriculturally important animal species. Research findings have associated Spirulina to improvements in animal growth, fertility, aesthetic and nutritional product quality. Spirulina intake has also been linked to an improvement in animal health and welfare. Its influence over animal development stems from its nutritive and protein-rich composition, thus leading to an increased commercial production to meet consumer demand. Consequently, Spirulina is emerging as a cost-effective means of improving animal productivity for a sustainable and viable food security future. However, our present knowledge of animal response to dietary Spirulina supplementation is relatively scanty and largely unknown. Therefore, the primary objective of this paper was to review past and current findings on the utilisation of Spirulina as a feed supplement and its impact on animal productivity and health. Only animals deemed to be of agricultural significance were investigated; hence, only ruminants, poultry, swine and rabbits and their responses to dietary Spirulina supplementation are covered. © 2012 Blackwell Verlag GmbH.

Full Text Available The article describes selection process of sustainable technological process flow chart for water treatment procedure developed on scientifically based calculated indexes of quality indicators for water supplied to water treatment facilities. In accordance with the previously calculated values of the indicators of the source water quality, the main purification facilities are selected. A more sustainable flow chart for the modern water quality of the Seversky Donets-Donbass channel is a two-stage filtering with contact prefilters and high-rate filters. The article proposes a set of measures to reduce such an indicator of water quality as permanganate oxidation. The most suitable for these purposes is sorption purification using granular activated carbon for water filtering. The increased water hardness is also quite topical. The method of ion exchange on sodium cation filters was chosen to reduce the water hardness. We also evaluated the reagents for decontamination of water. As a result, sodium hypochlorite is selected for treatment of water, which has several advantages over chlorine and retains the necessary aftereffect, unlike ozone. A technological flow chart with two-stage purification on contact prefilters and two-layer high-rate filters (granular activated carbon - quartz sand with disinfection of sodium hypochlorite and softening of a part of water on sodium-cation exchangers filters is proposed. This technological flow chart of purification with any fluctuations in the quality of the source water is able to provide purified water that meets the requirements of the current sanitary-hygienic standards. In accordance with the developed flow chart, guidelines and activities for the reconstruction of the existing Makeevka Filtering Station were identified. The recommended flow chart uses more compact and less costly facilities, as well as additional measures to reduce those water quality indicators, the values of which previously were in

Protein and energy supplementation in elderly people at risk from malnutrition.
Milne, Anne C; Potter, Jan; Vivanti, Angela; Avenell, Alison
2009-04-15
Evidence for the effectiveness of nutritional supplements containing protein and energy, often prescribed for older people, is limited. Malnutrition is more common in this age group and deterioration of nutritional status can occur during illness. It is important to establish whether supplementing the diet is an effective way of improving outcomes for older people at risk from malnutrition. This review examined trials for improvement in nutritional status and clinical outcomes when extra protein and energy were provided, usually as commercial 'sip-feeds'. We searched The Cochrane Library, MEDLINE, EMBASE, Healthstar, CINAHL, BIOSIS, CAB abstracts. We also hand searched nutrition journals and reference lists and contacted 'sip-feed' manufacturers. Randomised and quasi-randomised controlled trials of oral protein and energy supplementation in older people, with the exception of groups recovering from cancer treatment or in critical care. Two reviewers independently assessed trials prior to inclusion and independently extracted data and assessed trial quality. Authors of trials were contacted for further information as necessary. Sixty-two trials with 10,187 randomised participants have been included in the review. Maximum duration of intervention was 18 months. Most included trials had poor study quality. The pooled weighted mean difference (WMD) for percentage weight change showed a benefit of supplementation of 2.2% (95% confidence interval (CI) 1.8 to 2.5) from 42 trials. There was no significant reduction in mortality in the supplemented compared with control groups (relative risk (RR) 0.92, CI 0.81 to 1.04) from 42 trials. Mortality results were statistically significant when limited to trials in which participants (N = 2461) were defined as undernourished (RR 0.79, 95% CI 0.64 to 0.97).The risk of complications was reduced in 24 trials (RR 0.86, 95% CI 0.75 to 0.99). Few trials were able to suggest any functional benefit from supplementation. The WMD for length

Full Text Available Slope excavation is one of the most crucial steps in the construction of a hydraulic project. Excavation project quality assessment and excavated volume calculation are critical in construction management. The positioning of excavation projects using traditional instruments is inefficient and may cause error. To improve the efficiency and precision of calculation and assessment, three-dimensional laser scanning technology was used for slope excavation quality assessment. An efficient data acquisition, processing, and management workflow was presented in this study. Based on the quality control indices, including the average gradient, slope toe elevation, and overbreak and underbreak, cross-sectional quality assessment and holistic quality assessment methods were proposed to assess the slope excavation quality with laser-scanned data. An algorithm was also presented to calculate the excavated volume with laser-scanned data. A field application and a laboratory experiment were carried out to verify the feasibility of these methods for excavation quality assessment and excavated volume calculation. The results show that the quality assessment indices can be obtained rapidly and accurately with design parameters and scanned data, and the results of holistic quality assessment are consistent with those of cross-sectional quality assessment. In addition, the time consumption in excavation quality assessment with the laser scanning technology can be reduced by 70%–90%, as compared with the traditional method. The excavated volume calculated with the scanned data only slightly differs from measured data, demonstrating the applicability of the excavated volume calculation method presented in this study.

Full Text Available The aim of this work was to improve the quality of gluten-free bread made with high content of soy flour and enriched with sugar beet molasses by incorporating ingredients with a potential to simultaneously enhance the nutritional quality of the breads. The following ingredients were used: pea protein isolate, pea fibre and chia seeds. The chosen ingredients exerted positive effects on bread quality. They promoted volume increase and crumb softening. In this respect, the most effective ingredients were pea protein isolate (at 1% supplementation level, pea fibre (at up to 2% supplementation level and chia seeds (at 1% supplementation level. The sensory analysis revealed that pea fibre and chia addition at 1 and 2% supplementation level provided bread with higher scores regarding overall acceptance, crumb texture and taste. At 1% supplementation level, there was not found statistically significant difference in sensory attributes of bread supplemented with pea protein isolate in comparison to the control. However, pea protein isolate was found to strongly diminish bread taste at 4% supplementation level due to presence of beany taste.

This report summarizes the consensus findings and recommendations emerging from 2007 Symposium, 'Quality Assurance of Radiation Therapy: Challenges of Advanced Technology.' The Symposium was held in Dallas February 20-22, 2007. The 3-day program, which was sponsored jointly by the American Society for Therapeutic Radiology and Oncology (ASTRO), American Association of Physicists in Medicine (AAPM), and National Cancer Institute (NCI), included >40 invited speakers from the radiation oncology and industrial engineering/human factor communities and attracted nearly 350 attendees, mostly medical physicists. A summary of the major findings follows. The current process of developing consensus recommendations for prescriptive quality assurance (QA) tests remains valid for many of the devices and software systems used in modern radiotherapy (RT), although for some technologies, QA guidance is incomplete or out of date. The current approach to QA does not seem feasible for image-based planning, image-guided therapies, or computer-controlled therapy. In these areas, additional scientific investigation and innovative approaches are needed to manage risk and mitigate errors, including a better balance between mitigating the risk of catastrophic error and maintaining treatment quality, complimenting the current device-centered QA perspective by a more process-centered approach, and broadening community participation in QA guidance formulation and implementation. Industrial engineers and human factor experts can make significant contributions toward advancing a broader, more process-oriented, risk-based formulation of RT QA. Healthcare administrators need to appropriately increase personnel and ancillary equipment resources, as well as capital resources, when new advanced technology RT modalities are implemented. The pace of formalizing clinical physics training must rapidly increase to provide an adequately trained physics workforce for advanced technology RT. The specific

The effects of dietary inclusion of Cistus ladanifer L. (CL) and a vegetable oil blend were evaluated on growth performance,carcass and meat quality of fifty four lambs that were assigned to 9 diets, corresponding to 3 levels of CL(50, 100 and 200 g/kg DM) and 3 levels of oil inclusion (0, 40 and 80 g/kg DM). Treatments had no effects on growth rate. Oil depressed dry matter intake (P = 0.017), carcass muscle (P = 0.041) and increased (P = 0.016) kidney knob channel fat. Chemical and physical meat quality traits were not affected by treatments. Off-flavour perception was higher for 8% of oil (P b 0.001). The level of 100 g/kg DM of CL inclusion improved meat stability after 7 days of storage. Supplementation with linseed and soybean oils (2:1) was a good approach to improve meat nutritional value from feedlot lambs, increasing total n-3 PUFA.

Will the new Consumer Protection Act prevent harm to nutritional supplement users?
Gabriels, Gary; Lambert, Mike; Smith, Pete; Hiss, Donavon
2011-07-25
BACKGROUND. There is no clear distinction between the regulation of food, supplements and medicines in South Africa. Consequently, grey areas exist in implementing the legislation, particularly in the supplement industry. The increase in supplement sales in South Africa can be attributed to aggressive marketing by manufacturers whose claims are not always supported by published peer-reviewed evidence. Such claims often go unchecked, resulting in consumers being mislead about the role of supplements. As a result of poor regulation, contaminants or adulterants in supplements may also cause insidious effects unrelated to the listed ingredients. AIM. To assess the regulations, legislation, and claims associated with nutritional supplement products in South Africa. METHOD. Peer-reviewed literature and the relevant South African statutes were consulted. RESULTS. The National Health Act incorporates the Medicine Control Council, which is charged with ensuring the safety, quality and effectiveness of medicines, and related matters, including complementary/alternative medicines. The South African Institute for Drug-Free Sport and Amendment Act provides for testing athletes for using banned substances, but currently does not concern itself with monitoring nutritional supplements for contaminants or adulterants that may cause a positive drug test, which has implications for sports participants and also the health of the general population. The implementation of the Consumer Protection Act 68 of 2008 (CPA) could protect consumer rights if it is administered and resourced appropriately. CONCLUSION. The CPA should promote greater levels of policy development, regulatory enforcement, and consumer education of South Africa's supplement industry.

Highlights: • House of Quality method was used for assessment of coal pyrolysis polygeneration technologies. • Low rank coal pyrolysis polygeneration processes based on solid heat carrier, moving bed and fluidized bed were evaluated. • Technical and environmental criteria for the assessment of technologies were used. • Low rank coal pyrolysis polygeneration process based on a fluidized bed is the best option. - Abstract: Increasing interest in low rank coal pyrolysis (LRCP) polygeneration has resulted in the development of a number of different technologies and approaches. Evaluation of LRCP processes should include not only conventional efficiency, economic and environmental assessments, but also take into consideration sustainability aspects. As a result of the many complex variables involved, selection of the most suitable LRCP technology becomes a challenging task. This paper applies a House of Quality method in comprehensive evaluation of LRCP. A multi-level evaluation model addressing 19 customer needs and analyzing 10 technical characteristics is developed. Using the evaluation model, the paper evaluates three LRCP technologies, which are based on solid heat carrier, moving bed and fluidized bed concepts, respectively. The results show that the three most important customer needs are level of technical maturity, wastewater emissions, and internal rate of return. The three most important technical characteristics are production costs, investment costs and waste emissions. On the basis of the conducted analysis, it is concluded that the LRCP process utilizing a fluidized bed approach is the optimal alternative studied

The increase in sales of nutritional supplement globally can be attributed, in part, to aggressive marketing by manufacturers, rather than because the nutritional supplements have become more effective. Furthermore, the accuracy of the labelling often goes unchallenged. Therefore, any effects of the supplement, may be due to contaminants or adulterants in these products not reflected on the label. A self-administered questionnaire was used to determine how consumers of nutritional supplements acquired information to assist their decision-making processes, when purchasing a product. The study was approved by the University of Cape Town, Faculty of Health Sciences Human Research Ethics Committee. The questionnaire consisted of seven, closed and open-ended questions. The participants were asked to respond to the questions according to a defined list of statements. A total of 259 participants completed and returned questionnaires. The data and processing of the returned questionnaires was captured using Windows-based Microsoft® Office Excel 2003 SP 1 (Excel © 1985-2003 Microsoft Corporation). Statistica Version 10 (copyright © Stat Soft, Inc. 1984-2011) was used to calculate the descriptive statistics. The main finding of the study was that nearly 70% of the respondents who purchased supplements were strongly influenced by container label information that stipulated that the nutritional supplement product is free of banned substances. The second finding was that just over 50% of the respondents attached importance to the quality of the nutritional supplement product information on the container label. The third finding was that about 40% of the respondents were strongly influenced by the ingredients on the labels when they purchased nutritional supplements. This study, (i) identifies short-comings in current labelling information practices, (ii) provides opportunities to improve label and non-label information and communication, and, (iii) presents the case for

The aim of the present study was to evaluate different concentrations of royal jelly (RJ) supplemented extenders for post-thaw quality and incubation resilience of goat spermatozoa. Semen samples were collected from five goats. Pooled semen were diluted with soybean lecithin-based extender without RJ (control) or supplemented with different concentrations (0.25, 0.5 and 0.75%) of RJ (RJ0.25, RJ0.5, RJ0.75 respectively), at a final concentration of 150 × 10 6 spermatozoon/mL. Semen samples were assessed for sperm motility, plasma membrane integrity using hypoosmotic swelling test (HOST) damaged acrosome using FITC-Pisum sativum agglutinin (PSA-FITC) and DNA integrity using terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL). The addition of RJ (0.5%, 0.75%) led to higher percentages of subjective motilities (55.33 ± 2.29%, 57.67 ± 2.58%) compared to control and RJ0.25 groups (49.00 ± 2,80%, 51.67 ± 3.09%) (P 0.05). In the end of incubation, motility and HOST rates of RJ0.5 (14.00 ± 3.87%, 31.20 ± 3.70%) and RJ0.75 (15.00 ± 3.27%, 29.20 ± 2.59%) groups were higher than control (8.00 ± 2.54%, 18.20 ± 3.11%) and RJ0.25 (9.00 ± 2.07%, 20.60 ± 2.88%) groups (P < 0.05). Also defected acrosome and DNA fragmation rates of RJ0.5 (32.20 ± 1.30%, 5.4 ± 0.55%) and RJ0.75 (29.20 ± 1.30%, 5.80 ± 0.45%) groups were significantly lower than control (38.80 ± 0.84%, 7.40 ± 1.34%) and RJ0.25 (39.80 ± 2.05%, 7.00 ± 1.58) groups. This study shows that RJ supplemented extenders have beneficial effect on goat sperm parameters at 0 h and 6 h of incubation. Copyright © 2016 Elsevier Inc. All rights reserved.

Protein supplementation with sports protein bars in renal patients.
Meade, Anthony
2007-05-01
Malnutrition prevalence in patients on dialysis is well established. The protein requirements for both hemodialysis and peritoneal dialysis have been documented elsewhere, including the Kidney Disease Outcomes Quality Initiative Clinical Practice Guidelines for Nutrition in Chronic Renal Failure. The clinical challenge is to assist patients in meeting these targets, especially in those with anorexia. Traditional supplements have included fluid, which is an issue for patients who are fluid restricted. The study objectives were to (1) investigate the range of sports protein supplements that may be suitable for patients on hemodialysis to use and (2) trial nonfluid protein supplements in patients on hemodialysis. Known manufacturers of sports protein bars and other sports supplements available in Australia were contacted for the nutrient breakdown of high-protein products, specifically potassium, protein, and phosphorus contents. As a result, selected high-protein sports bars (Protein FX, Aussie Bodies, Port Melbourne, Victoria, Australia) were used as an alternative to the more commonly used renal-specific fluid supplements (Nepro, Abbott Laboratories, Abbott Park, IL; Novasource Renal, Novartis Nutrition Corporation, Fremont, MI; and Renilon, Nutricia, Wiltshire, UK) in patients with poor nutritional status requiring supplementation. Patient satisfaction and clinical nutrition markers were investigated. The study took place at inpatient, in-center, and satellite hemodialysis settings in Adelaide, South Australia. A total of 32 patients (16 females and 16 males) with an average age of 62.9 years (range 32-86 years) undergoing hemodialysis (acute and maintenance) were included. Subjects were selected by the author as part of routine clinical nutrition care. Patients trialed sports protein bars as a protein supplement alone or in conjunction with other supplementary products. All patients were in favor of the trial, with 22 of 32 patients continuing with the protein

Full Text Available Afield trial was carried out with eight cultivars (Libellula, Drina, Sremica NSR-2, Jugoslavija, Somborka, Lasta and Pobeda of winter wheat (Trticum aestivum L representing several different periods in our country's wheat selection and having different potentials for technological grain quality. Six different rates of nitrogen fertilizer were tested: 0, 60, 90, 120, 150 and 180 kgNha-1. Increasing N fertilizer rates resulted in a linear increase of the direct and indirect indicators of quality. The best results were obtained with the cultivar Sremica and the poorest with Lasta, while Jugoslavija and Pobeda were shown to be of approximately the same quality. The contribution of N fertilizer variance to total variance was the largest for protein content (43.7%. N nutrition had a greater influence on protein content in cultivars from the earlier periods of selection. Its effect on sedimentation value, on the other hand, was greater in the recently released cultivars. The contribution of the genetic factor to total variance was the highest for crumb value number (CVN (58.7% and bread volume yield (44.2% and the lowest for protein content (20.8%. The absence of significant differences in the CVN means at any of the N nutrition levels studied resulted from the variability of the indirect indicators closely linked with the direct indicators of baking quality, showing the importance of N nutrition for maintaining the stability of technological quality in winter wheat cultivars.

As physical restraints should only be used in exceptional cases, there is an urgent need for alternatives to restraint use. Surveillance technology could be such an alternative. This study explored whether nursing-home residents with dementia subjected to surveillance technology had better quality of life scores for mood, behavioral and societal dimensions than residents with physical restraints. Quality of life was assessed longitudinally, with three measurements in six psychogeriatric nursing homes of residents with surveillance technology (n = 170) and residents with physical restraints (n = 22). QUALIDEM subscales were used to measure five dimensions of quality of life. Multilevel longitudinal univariate and multivariate regression techniques were used to analyze the data. Because physical restraints were almost exclusively used in residents with low activities of daily living (ADL) independency (18 of the 22), we restricted the regression analyses to residents with a Barthel Index score ≤ 5 (overall n = 53). Univariate results showed that highly ADL-dependent residents with surveillance technology had significantly more positive affect than highly ADL-dependent residents with physical restraints. However, this difference proved to be no longer significant after adjustment for the confounders: age, sex and stage of dementia. Quality of life of highly ADL-dependent nursing-home residents with dementia seems to be unrelated to the use of surveillance technology as opposed to physical restraints.

Background: Consumers increasingly choose food supplements in addition to their diet. Research on supplement users finds they are likely to be female, older and well-educated; Furthermore, supplement users are often characterised as being especially health-oriented, an observation which is termed...... the ‘inverse supplement hypothesis’. However, results are dependent on the substance in question. Little is known so far about botanicals in general, and more specifically, little is known about resveratrol. The psychographic variables of food supplement users are yet relatively underexplored. By comparing US...... and Danish respondents, we aimed to identify whether sociodemographic variables, health status, health beliefs and behaviour and interest in food aspects specifically relevant to resveratrol (e.g., naturalness, indulgence, and Mediterranean food) explain favourable attitudes and adoption intentions toward...

Given the expanding market of plant food supplements (PFSs) not undergoing any pre-marketing authorization, the overall quality, safety and efficacy of PFSs were subjected to a critical examination. Although many high-quality PFSs exist on the legal market, quality concerns are in general justified. Besides economic adulteration, active ingredients dramatically differing from label claims and among products were reported in several studies. In addition, PFSs sold via the Internet may be intentionally adulterated with undeclared prescription drugs. Compared to PFSs with only one single herb, PFSs containing herbal mixtures were more involved in moderate and severe clinical courses. Although prohibited by regulation, misleading labels on PFSs are common. Above all, only vague evidence for the efficacy of PFSs exists. Notwithstanding the unproven efficacy and insufficient safety assessment, PFSs represent a relevant source for consumers to get access to herbal preparations in the United States and meanwhile also in Europe, as launching of licensed/registered European herbal medicinal products (HMPs) has steadily decreased. However, being non-vitamin, non-mineral products, PFSs are neither food nor drugs. In terms of protecting public health and providing the consumer with high-quality, effective, and safe PFSs, possibilities are shown how to deal with the many challenges of PFSs. Last but not least, suggestions are made for assigning PFSs a separate regulatory category being less regulated compared to HMPs but more strictly regulated compared to food laws including implementation of good manufacturing practices and a scientific pre-marketing review process by an expert commission.

The marketing of dietary supplements in North America: the emperor is (almost) naked.
Temple, Norman J
2010-07-01
Many different dietary supplements are being sold in North America. The quality of the evidence supporting their efficacy covers a wide spectrum: Some are based on solid science (such as vitamin D and fish oil), whereas with most supplements there is little or no supporting evidence. Types of supplements commonly sold include exotic fruit juices (such as goji juice) and single herbs or mixture of herbs. Common claims made in support of particular supplements are that they are rich in antioxidants, induce detoxification, stimulate the immune system, and cause weight loss. Supplements are commonly sold through health food stores and by multilevel marketing. Sales may be promoted using bulk mail ("junk mail"), spam e-mails, and Web sites. A large part of marketing is based on claims that are blatantly dishonest. Whereas supplements for which good supporting evidence exists generally cost around $3-$4 per month, those that are heavily promoted for which there is little supporting evidence cost about $20-$60 per month. The major cause of this problem in the United States is weakness of the law. There is an urgent need for stricter regulation and for giving better advice to the general public.

High-risk medical devices often undergo modifications, which are approved by the US Food and Drug Administration (FDA) through various kinds of premarket approval (PMA) supplements. There have been multiple high-profile recalls of devices approved as PMA supplements. To characterize the quality of the clinical studies and data (strength of evidence) used to support FDA approval of panel-track supplements (a type of PMA supplement pathway that is used for significant changes in a device or indication for use and always requires clinical data). Descriptive study of clinical studies supporting panel-track supplements approved by the FDA between April 19, 2006, and October 9, 2015. Panel-track supplement approval. Methodological quality of studies including randomization, blinding, type of controls, clinical vs surrogate primary end points, use of post hoc analyses, and reporting of age and sex. Eighty-three clinical studies supported the approval of 78 panel-track supplements, with 71 panel-track supplements (91%) supported by a single study. Of the 83 studies, 37 (45%) were randomized clinical trials and 25 (30%) were blinded. The median number of patients per study was 185 (interquartile range, 75-305), and the median follow-up duration was 180 days (interquartile range, 84-270 days). There were a total of 150 primary end points (mean [SD], 1.8 [1.2] per study), and 57 primary end points (38%) were compared with controls. Of primary end points with controls, 6 (11%) were retrospective controls and 51 (89%) were active controls. One hundred twenty-one primary end points (81%) were surrogate end points. Thirty-three studies (40%) did not report age and 25 (30%) did not report sex for all enrolled patients. The FDA required postapproval studies for 29 of 78 (37%) panel-track supplements. Among clinical studies used to support FDA approval of high-risk medical device modifications, fewer than half were randomized, blinded, or controlled, and most primary outcomes were

Dietary supplement use is endemic in young athletes; however, it is unclear if their choices are congruent with their motivation for supplementation and the established benefits of the dietary supplements. The aim of this study was to evaluate the relationships between dietary supplement use and self-reported rationale in young athletes. Canadian athletes (n = 567; 11-25 years; 76% club or provincial level, 24% national or higher) completed a questionnaire designed to assess supplementation patterns and motivation for supplementation. Chi square tests examined associations between dietary supplements and self-reported rationale for use. Vitamin and mineral supplements, including vitamin-enriched water, were associated with several health- and performance- related reasons (p performance reasons, as were performance foods (protein powder, sport bars, sport gels, etc.). Plant extracts and fatty acids were primarily associated with health reasons, particularly immune support (p performance rationales and supplementation for common ergogenic aids, however, less so for vitamin and mineral supplements, vitamin-enriched water, and plant extracts. Incongruences were found between fatty acids, protein supplements, vitamin and mineral supplements, vitamin-enriched water, and plant extracts and health motivators for supplementation. Educational interventions are essential to ensure young athletes are using dietary supplements safely and effectively.

An experiment was conducted to determine whether, by using a low-protein amino acid-supplemented diet, the health status, stress response, and excreta quality could be improved without affecting the productive performance of heat-stressed laying hens. The requirements for egg production, egg mass, and feed conversion ratio were also estimated using second-order equations and broken-line regression. A total of 150 Lohmann Selected Leghorn (LSL-Lite) hens were divided randomly into five groups of 30 with five replicates of six hens. The hens were raised for an 8-week period (52 to 60 weeks) in wire cages situated in high ambient temperature in an open-sided housing system. The five experimental diets (ME; 2,720 kcal/kg) varied according to five crude protein (CP) levels: normal-CP diet (control, 16.5 % CP) and low-CP diets containing 15.0, 13.5, 12.0, or 10.5 % CP. All experimental diets were supplemented with crystalline amino acids at the levels sufficient to meet their requirements. The results showed that under high temperature conditions, all productive performance and egg quality parameters in the birds fed with 15.0, 13.5, and 12.0 % CP diets were similar to those of birds fed with control diet (16.5 % CP), whereas feeding 10.5 % CP diet significantly decreased egg production and egg mass. Estimations of requirements were of 13.93 and 12.77 % CP for egg production, 14.62 and 13.22 % CP for egg mass, and 12.93 and 12.26 % CP for feed conversion ratio using quadratic and broken-line models, respectively. Egg yolk color index, blood triglyceride level, and excreta acidity were also significantly higher in birds fed with 12.0 and 10.5 % CP diets compared with those of control birds. The heterophil to lymphocyte ratio, as a stress indicator, was significantly decreased by 15.0, 13.5, and 12 % CP diets. On the basis of our findings, reducing dietary CP from 16.5 to 12.0 % and supplementing the diets with the essential amino acids showed merit for improving the

Background Iron and folic acid supplementation has been the preferred intervention to improve iron stores and prevent anaemia among pregnant women, and it may also improve other maternal and birth outcomes. Objectives To assess the effects of daily oral iron supplements for pregnant women, either alone or in conjunction with folic acid, or with other vitamins and minerals as a public health intervention. Search methods We searched the Cochrane Pregnancy and Childbirth Group’s Trials Register (2 July 2012). We also searched the WHO International Clinical Trials Registry Platform (ICTRP) (2 July 2012) and contacted relevant organisations for the identification of ongoing and unpublished studies. Selection criteria Randomised or quasi-randomised trials evaluating the effects of oral preventive supplementation with daily iron, iron + folic acid or iron + other vitamins and minerals during pregnancy. Data collection and analysis We assessed the methodological quality of trials using standard Cochrane criteria. Two review authors independently assessed trial eligibility, extracted data and conducted checks for accuracy. Main results We included 60 trials. Forty-three trials, involving more than 27,402 women, contributed data and compared the effects of daily oral supplements containing iron versus no iron or placebo. Overall, women taking iron supplements were less likely to have low birthweight newborns (below 2500 g) compared with controls (8.4% versus 10.2%, average risk ratio (RR) 0.81; 95% confidence interval (CI) 0.68 to 0.97, 11 trials, 8480 women) and mean birthweight was 30.81 g greater for those infants whose mothers received iron during pregnancy (average mean difference (MD) 30.81; 95% CI 5.94 to 55.68, 14 trials, 9385 women). Preventive iron supplementation reduced the risk of maternal anaemia at term by 70% (RR 0.30; 95% CI 0.19 to 0.46, 14 trials, 2199 women) and iron deficiency at term by 57% (RR 0.43; 95% CI 0.27 to 0.66, seven trials, 1256 women

Full Text Available The high unsaturation levels of spermatozoal membrane make it very susceptible to oxidative damage and this problem increases with advancing age. In this study, the aim is to investigate whether parsley seed (PS has a protective effect on semen quality, serum lipid profile and antioxidative status of old and young bucks. Male rabbits (n= 36 (18 young 9-12 mo old and 18 old 36-42 mo old were each assigned to 3 dietary treatments (a control and 2 levels of PS: 0.3 and 0.6 kg/100 kg diet to evaluate the ability of parsley to enhance bucks’ reproductive status. Most of the studied traits were adversely affected by age of rabbit bucks. On the other hand, the inclusion of PS significantly boosted ejaculate volume and improved mass motility concentration and total sperm output. Seminal plasma and blood serum total antioxidant capacity increased, while serum lipid peroxidase decreased with parsley treatments. In conclusion, dietary supplementation of parsley seed alleviates most semen quality parameters and counteracts oxidative stress, especially with the advance of age (seminal plasma and blood serum of total antioxidant capacity and malondialdehyde.

Soybean seeds, rich in protein and oil, maintain their germinability only for short durations under ambient conditions. Loss of viability of stored seeds often hampers soybean production in harsh environments worldwide. Physiological factors favored by high temperature and high moisture content accelerate the seed deterioration in the tropics. Several chemical and physical treatments are being used to enhance quality. Irradiation is a novel technology for food preservation and is gaining importance all over the world. Low doses of irradiation bring about improvement in quality of food/seeds, which can be beneficial in several ways. Electron Beam (EB) irradiation is a new approach in this area. The objective of present study was to investigate the effect of EB irradiation in enhancing the quality of low vigour soybean seeds

A 5-time designated Magnet academic medical center partnered with its infusion systems supplier to successfully integrate 1327 smart pumps across 45 departments with an aggressive 3-month timeline. The team also achieved quality improvement (QI) outcomes through increased drug library compliance and decreased alerts with their new technology. This large academic medical center needed to implement innovative wireless infusion pump technology in a short time frame. The approach involved a strong partnership from the medical center and the supplier, with extensive planning and collaboration among the clinical nurse specialists and consultants from both organizations to accomplish QI goals. Lean principles were also followed to enhance efficiency and accountability. Quality improvement outcomes included 100% drug library compliance across all 6 intensive care units, a decrease in pump alert rates from 4.18% to 0.79%, and a decrease in pump programming correction rate from 0.36% to 0.06%. A partnership led to a large implementation being completed efficiently across an academic medical center. Through these joint efforts, quality of care was improved within a short period of time.This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

This paper proposes a theoretical framework for a Quality of Life (QOL) evaluation tool that is sensitive, flexible, computerized, and specific to assistive technology (AT) for dementia care. Using the appropriate evaluation tool serves to improve methodologies that are used for AT assessment...... to assessing QOL is that results are subjective and difficult to analyze in an objective, empirical manner. This paper accentuates that this is not a hindrance to measuring OQL, but could be emphasized and adapted to create a precise measurement tool; the consumer voice must be sought and empowered...

Oak Ridge National Laboratory has developed and is continuing to refine a method of immobilizing low-level radioactive liquid wastes by mixing them with cementitious dry-solid blends. A quality assurance program is vital to the project because Nuclear Regulatory Commission (NRC), Environmental Protection Agency (EPA) and state environmental regulations must be demonstrably met (the work must be defensible in a court of law). The end result of quality assurance (QA) is, by definition, a product of demonstrable quality. In the laboratory, this entails traceability, repeatability, and credibility. This paper describes the application of QA in grout technology development at Oak Ridge National Laboratory

Bud extracts, named also "gemmoderivatives", are a new category of natural products, obtained macerating meristematic fresh tissues of trees and plants. In the European Community these botanical remedies are classified as plant food supplements. Nowadays these products are still poorly studied, even if they are widely used and commercialized. Several analytical tools for the quality control of these very expensive supplements are urgently needed in order to avoid mislabelling and frauds. In fact, besides the usual quality controls common to the other botanical dietary supplements, these extracts should be checked in order to quickly detect if the cheaper adult parts of the plants are deceptively used in place of the corresponding buds whose harvest-period and production are extremely limited. This study aims to provide a screening analytical method based on UV-VIS-Fluorescence spectroscopy coupled to multivariate analysis for a rapid, inexpensive and non-destructive quality control of these products.
