Diseases linked to obesity such as cardiovascular disease, diabetes, degenerative joint disease, gastroesophageal reflux, and sleep apnea constitute a large portion of primary care visits. Patients with these conditions often lack knowledge, skills, and support needed to maintain health. Shared medical appointments (SMAs) that include culinary skills and nutrition education offer a novel, cost-effective way to address these diseases in primary care. Adult patients in a primary care practice at a large academic hospital in Boston, Massachusetts, who had at least 1 cardiovascular risk factor were invited to participate in SMAs that included cooking demonstrations and teaching about nutrition in addition to medical management of their conditions. Sessions were conducted by a physician and an assistant in a conference room of a traditional primary care practice as part of a pilot feasibility project. Seventy patients, contributing a total of 156 patient visits, attended 17 nutrition-focused SMAs over a 4-year period. Patients were surveyed after each visit and indicated that they enjoyed the SMAs, would consider alternating SMAs with traditional one-on-one visits, and would recommend SMAs to others. Half would pay out of pocket or a higher copay to attend SMAs. Financially, the practice broke even compared with traditional one-onone office visits. In this feasibility study, chronic disease SMAs conducted with a culinary/nutrition focus were feasible, cost-effective, and well received by patients. Follow-up studies are needed to evaluate short- and long-term outcomes of this SMA model on obesity-related diseases.

Full Text Available Stephanie K Danforth,1 Julie Raeder Schumacher,2 Robert W Cullen,2 Yoon Jin Ma2 1University of Iowa Hospital, Iowa City, IA, USA; 2Department of Family and Consumer Sciences, Illinois State University, Normal, IL, USA Abstract: Video podcasts, termed “vodcasts”, offer viewers a visual aid when learning about health and nutrition. Although there are many vodcasts featuring cooking demonstrations, little is known about their effectiveness in the field of nutrition or which format of communication technology is preferred. The purpose of this study was to determine which vodcast format was best suited to increase nutrition knowledge and interest as well as intention to use a cancer-preventing food. Participants were recruited from a community cancer center in the Midwest region of the United States. The convenience sample received either an email or an information card from the center that contained a link to the online survey instrument. The survey consisted of initial questions, the vodcast link, and access to final survey questions after viewing the vodcast. Participants (n=120 viewed one of three vodcast formats and evaluated length, nutrition information, and cooking instruction. Nutrition knowledge and the effect each video had on participants' interest and intention to use the food were also measured. A vodcast containing four to six nutrition facts and demonstrating a recipe was preferred by most individuals (X2=10.954, df =4, P=0.027. Participants were indifferent regarding length preference. All formats were successful in increasing interest in cancer-preventing foods and delivering nutrition information to participants. Vodcasts containing a recipe demonstration may offer a convenient method of delivering nutrition information to community members. Keywords: community, dietetics, podcasts

The aim of this study was evaluating if the presence of a humanoid robot could improve the efficacy of a game-based, nutritional education intervention. This was a controlled, school-based pilot intervention carried out on fourth-grade school children (8-10 years old). A total of 112 children underwent a game-based nutritional educational lesson on the importance of carbohydrates. For one group (n = 58), the lesson was carried out by a nutritional educator, the Master of Taste (MT), whereas for another group, (n = 54) the Master of Taste was supported by a humanoid robot (MT + NAO). A third group of children (n = 33) served as control not receiving any lesson. The intervention efficacy was evaluated by questionnaires administered at the beginning and at the end of each intervention. The nutritional knowledge level was evaluated by the cultural-nutritional awareness factor (AF) score. A total of 290 questionnaires were analyzed. Both MT and MT + NAO interventions significantly increased nutritional knowledge. At the end of the study, children in the MT and MT + NAO group showed similar AF scores, and the AF scores of both intervention groups were significantly higher than the AF score of the control group. This study showed a significant increase in the nutritional knowledge of children involved in a game-based, single-lesson, educational intervention performed by a figure that has a background in food science. However, the presence of a humanoid robot to support this figure's teaching activity did not result in any significant learning improvement. Copyright © 2016 The Royal Society for Public Health.

2006-12-01

Accelerator driven sub-critical reactors are subject of many research programmes since more than ten years, with the aim of testing the feasibility of the concept as well as their efficiency as a transmutation tool. Several key points like the accelerator, the spallation target, or neutronics in a subcritical medium were investigated extensively these last years, allowing for technological choices and the design of a low power European demonstration ADS (a few tens of MWth). Programmes dedicated to subcritical reactor piloting proposed a monitoring procedure to be validated in forthcoming experiments. Accelerator R and D provided the design of a LINAC for an ADS and research work on accelerator reliability is going on. A spallation target was operated at PSI and the design of a windowless target is in progress. All this research work converges to the design of a European demonstration ADS, the ETD/XT-ADS, which could be the Belgian MYRRHA project. (author)

Full Text Available The Department of Basic Education (DBE has not given nutrition education the necessary emphasis that it needs, despite its importance in South African schools. Nutrition is included as only one of many topics forming part of the Life Orientation syllabus. Educators are role models for learners in making healthy food choices, however, studies have shown that major gaps exist in the health and nutrition-related knowledge and behaviour of educators. The objective of this research was to undertake a pilot study to determine the impact of a nutrition education programme (NEP on the nutrition knowledge of Life Orientation educators in public schools in South Africa (SA. An exploratory baseline survey, to determine the nutrition education practices in 45 purposively selected public schools, was carried out before the experimental nutrition education intervention study. A nutrition knowledge questionnaire was completed by 24 purposively selected educators, representing all nine provinces in SA, before and after a three-day NEP. Pre and post-NEP data were analysed on the Statistical Package for Social Sciences (SPSS for a Windows program version 17.0 for descriptive statistics, version 17.0. Paired t-tests measured statistically significant differences (p < 0.05 before and after the NEP. The knowledge of the respondents improved significantly after the NEP as the mean±s.d. score of correctly answered questions (n = 59 improved from 63.3±30.2% before to 80.6±21.1% after the NEP. The results proved that nutrition knowledge of Life Orientation educators in primary schools is not optimal, but can be improved by NEP.

A series of maintenance and repair work for normalization of the pilot scale vitrification demonstration facility was completed successfully to develop the waste treatment in high temperature and melting technology. It was investigated that the treatment of combustible and non-combustible wastes produced at the KAERI site is technically feasible in the pilot scale vitrification demonstration facility which is designed to be able to treat various kinds of radioactive wastes such as combustible and non-combustible wastes including soil and concrete. The vitrification test facility can be used as the R and D and the technology demonstration facility for melt decontamination of the metallic wastes which have a fixed specification. The modification of the RI storage room in the pilot scale vitrification demonstration facility and the licensing according to the facility modification were completed for the R and D on melt decontamination of dismantled metallic wastes which is carrying out as one of the national long-term R and D projects on nuclear energy. The lab-scale melt decontamination apparatus was installed in modified RI storage room and the characteristics of melt decontamination will be examined using various metallic wastes. It is expected that the economical feasibility on the volume reduction and recycle of metallic wastes will be escalated in the present situation when the unit cost for waste disposal has the tendency to grow up gradually. Therefore, the pilot scale vitrification demonstration facility can be used for the technology development for the volume reduction and recycle of the metallic wastes generated from on-going projects on the decommissioning of research reactors and the environmental restoration of uranium conversion plant, and for the treatment of radioactive solid wastes produced at the KAERI site

Full Text Available Body image and eating disorders have emerged as an essential facet of bio-psychosocial well-being. Although considered less prevalent in Ghana than in the West, body image and eating disorders are issues of global concern. One hundred (100 female participants with a mean age of approximately 21 years were recruited after informed consent for this pilot study. Results showed a positive correlation between body image and eating disorders. In addition, there was no significant difference between the levels of university education on female body image and eating distortions in Ghana. These findings underscore the importance for more future studies in nutritional psychology and related clinical management.

Interactive lecture demonstrations (ILDs) have repeatedly shown to be effective tools for improving student achievement in the context of learning physics. As a first step toward systematic development of interactive lecture demonstrations in ASTRO 101, the introductory astronomy survey course, a systematic review of education research, describing educational computer simulations (ECSs) reveals that initial development requires a targeted study of how ASTRO 101 students respond to ECSs in the non-science majoring undergraduate lecture setting. In this project we have adopted the process by which ILDs were designed, pilot-tested, and successfully implemented in the context of physics teaching (Sokoloff & Thornton, 1997; Sokoloff & Thornton, 2004). We have designed the initial pilot-test set of ASTRO 101 ILD instructional materials relying heavily on ECSs. Both an instructor’s manual and a preliminary classroom-ready student workbook have been developed, and we are implementing a pilot study to explore their effectiveness in communicating scientific content, and the extent to which they might enhance students’ knowledge of and perception about astronomy and science in general. The study design uses a pre-/post-test quasi-experimental study design measuring students’ normalized gain scores, calculated as per Hake (1998) and Prather (2009), using a slightly modified version of S. Slater’s (2011) Test Of Astronomy STandards TOAST combined with other instruments. The results of this initial study will guide the iterative development of ASTRO 101 ILDs that are intended to both be effective at enhancing student achievement and easy for instructors to successfully implement.

2016-05-01

Solar thermochemical H2O and CO2 splitting is a viable pathway towards sustainable and large-scale production of synthetic fuels. A reactor pilot plant for the solar-driven thermal dissociation of ZnO into metallic Zn has been successfully developed at the Paul Scherrer Institute (PSI). Promising experimental results from the 100-kWth ZnO pilot plant were obtained in 2014 during two prolonged experimental campaigns in a high flux solar simulator at PSI and a 1-MW solar furnace in Odeillo, France. Between March and June the pilot plant was mounted in the solar simulator and in-situ flow-visualization experiments were conducted in order to prevent particle-laden fluid flows near the window from attenuating transparency by blocking incoming radiation. Window flow patterns were successfully characterized, and it was demonstrated that particle transport could be controlled and suppressed completely. These results enabled the successful operation of the reactor between August and October when on-sun experiments were conducted in the solar furnace in order to demonstrate the pilot plant technology and characterize its performance. The reactor was operated for over 97 hours at temperatures as high as 2064 K; over 28 kg of ZnO was dissociated at reaction rates as high as 28 g/min.

Cu cermet anodes were tested for 213 to 614 hours with an in-situ deposited CEROX coating in a pilot cell operated by Reynolds Manufacturing Technology Laboratory. At high bath ratio ([approximately]1.5) and low current density (0.5 A/cm[sup 2]), a [ge]1 mm thick dense CEROX coating was deposited on the anodes. At lower bath ratios and higher current density, the CEROX coating was thinner and less dense, but no change in corrosion rate was noted. Regions of low current density on the anodes and sides adjacent to the carbon anode sometimes had thin or absent CEROX coatings. Problems with cracking and oxidation of the cermet substrates led to higher corrosion rates in a pilot cell than would be anticipated from lab scale results.

The overall objective of the HADES programme is the evaluation of the technical feasibility and safety of the disposal of radwaste in a deep clay formation. The pilot phase is aimed at demonstrating the system behaviour for those components of the system and those operations and issues which can be demonstrated directly. The time period considered covers a first phase of the development programme of the pilot project which includes: -The construction of a concrete lined tests drift of about 30 m length with a useful inner diameter of 3.5 m. In the lining, a number of openings or ports are foreseen for emplacing the various tests and sensors for the general auscultation in the host rock; - Mine-by test for the investigation of the response of the surrounding clay on the excavating; - CERBERUS test, a combined heating-irradiation test aiming at evaluating by simulation (electrical heaters and Co-60 radiation source) the impact of a HLW canister on its immediate near field; - Design of a gallery heating test for the demonstration by simulation of the behaviour of a concrete lined gallery structure and of the surrounding clay mass in a temperature field (TEMPPRES code for temperature and pressure evolution simulation). 21 refs

Adequate nutrition has long been considered a critical component for wound healing, but literature regarding the relationship between nutrition and venous ulcer (VU) healing is limited. A person's nutrition is affected by the availability of food as well as his/her overall health. Food sufficiency and nutrition are important concerns in the care of persons of low income with injection-related VUs, which tend to be large and slow to heal. A cross-sectional pilot study was conducted to explore the relationship between food sufficiency/security and nutrition with regard to demographic, wound, quality-of-life, physical activity, falls, and fall risk variables. Nutrition was examined using 2 well-developed instruments that measure food sufficiency/security and assess nutrition--the United States Department of Agriculture's Adult Food Sufficiency Questionnaire (FSQ) and the Nestle Mini Nutritional Assessment (MNA). All participants (N = 31, 54% men, mean age 56.1 ± 3.6 years, all African American) were recruited from an outpatient clinic. All had injection-related VUs from a history of injecting illicit substances. In terms of food sufficiency/security, most participants (26, 84%) reported having enough food in the house, but 10 (32%) worried about running out of food. From 16% to 22.6% of participants expressed concern with food sufficiency/security in terms of cutting meal size, eating less, hunger, and weight loss. Food sufficiency/security was high for 19 (61.3%), but 12 (39%) had marginal or lower food sufficiency/security. MNA scores showed 16 participants (52%) were at risk of malnutrition or malnourished. Low food sufficiency/security was significantly (P nutrition assessment scores were significantly associated (P nutrition assessment are important to assess in low-income persons with injection-related VUs. A number of significant relationships of the FSQ and MNA to other variables was found but needs further investigation with a larger sample.

The fluorosis derived from coal burning is a very serious problem in China. By using fluorine-fixing technology during coal burning we are able to reduce the release of fluorides in coal at the source in order to reduce pollution to the surrounding environment by coal burning pollutants as well as decrease the intake and accumulating amounts of fluorine in the human body. The aim of this study was to conduct a pilot experiment on calcium-based fluorine-fixing material efficiency during coal burning to demonstrate and promote the technology based on laboratory research. A proper amount of calcium-based fluorine sorbent was added into high-fluorine coal to form briquettes so that the fluorine in high-fluorine coal can be fixed in coal slag and its release into atmosphere reduced. We determined figures on various components in briquettes and fluorine in coal slag as well as the concentrations of indoor air pollutants, including fluoride, sulfur dioxide and respirable particulate matter (RPM), and evaluated the fluorine-fixing efficiency of calcium-based fluorine sorbents and the levels of indoor air pollutants. Pilot experiments on fluorine-fixing efficiency during coal burning as well as its demonstration and promotion were carried out separately in Guiding and Longli Counties of Guizhou Province, two areas with coal burning fluorosis problems. If the calcium-based fluorine sorbent mixed coal was made into honeycomb briquettes the average fluorine-fixing ratio in the pilot experiment was 71.8%. If the burning calcium-based fluorine-fixing bitumite was made into a coalball, the average of fluorine-fixing ratio was 77.3%. The concentration of fluoride, sulfur dioxide and PM10 of indoor air were decreased significantly. There was a 10% increase in the cost of briquettes due to the addition of calcium-based fluorine sorbent. The preparation process of calcium-based fluorine-fixing briquette is simple yet highly flammable and it is applicable to regions with abundant

To observe the effect of coix seed diet therapy on the nutritional status of peritoneal dialysis patients and to discuss the potential reasons. 30 dialysis patients with regular return visit to peritoneal dialysis center of Guangdong Provincial Hospital of Traditional Chinese Medicine were recruited and divided into two groups according to their willingness. 13 patients in control group continued their usual dialysis prescriptions and medications, whereas 30g of coix seed per day was added to the usual therapies of 17 patients in coix seed group. Changes in nutritional status of dialysis patients in two groups were evaluated after a 12-week treatment. Two patients (one in each group) quitted the study because of pulmonary infection. After treatment, the nutritional parameters of serum albumin level (P=0.004), total protein level (P=0.008), and body mass index (P=0.023) were increased significantly in coix seed group. And the statistical differences of serum albumin level and body mass index were significantly compared to control group (P=0.008 and P=0.032, respectively). Moreover, the C-reactive protein level had a significant decrease (P=0.001) and the clinical symptoms of dialysis patients including tiredness, anorexia, xerostomia, and abdominal distension showed a significant improvement (Pnutritional status of peritoneal dialysis patients by relieving digestive tract symptoms, increasing urinary volume, and meliorating micro-inflammatory state.

Everett, Randy L.; Aragon, Alicia R.; Siegal Malcolm D.; Dwyer, Brian P.

2005-01-01

The Arsenic Water Technology Partnership program is a multi-year program funded by a congressional appropriation through the Department of Energy. The program is designed to move technologies from benchscale tests to field demonstrations. It will enable water utilities, particularly those serving small, rural communities and Indian tribes, to implement the most cost-effective solutions to their arsenic treatment needs. As part of the Arsenic Water Technology Partnership program, Sandia National Laboratories is carrying out field demonstration testing of innovative technologies that have the potential to substantially reduce the costs associated with arsenic removal from drinking water. The scope for this work includes: (1) Selection of sites and identification of technologies for pilot demonstrations; (2) Laboratory studies to develop rapid small-scale test methods; and (3) Pilot-scale studies at community sites involving side-by-side tests of innovative technologies. The goal of site selection is to identify sites that allow examination of treatment processes and systems under conditions that are relevant to different geochemical settings throughout the country. A number of candidate sites have been identified through reviews of groundwater quality databases, conference proceedings and discussions with state and local officials. These include sites in New Mexico, Arizona, Colorado, Oklahoma, Michigan, and California. Candidate technologies for the pilot tests are being reviewed through vendor forums, proof-of-principle benchscale studies managed by the American Water Works Association Research Foundation (AwwaRF) and the WERC design contest. The review considers as many potential technologies as possible and screens out unsuitable ones by considering data from past performance testing, expected costs, complexity of operation and maturity of the technology. The pilot test configurations will depend on the site-specific conditions such as access, power availability

In this work, we investigate and experimentally demonstrate an orthogonal frequency division multiplexing (OFDM) based high speed wavelength-division multiplexed (WDM) visible light communication (VLC) system using an inter-block data precoding and superimposed pilots (DP-SP) based channel estimation (CE) scheme. The residual signal-to-pilot interference (SPI) can be eliminated by using inter-block data precoding, resulting in a significant improvement in estimated accuracy and the overall system performance compared with uncoded SP based CE scheme. We also study the power allocation/overhead problem of the training for DP-SP, uncoded SP and conventional preamble based CE schemes, from which we obtain the optimum signal-to-pilot power ratio (SPR)/overhead percentage for all above cases. Intra-symbol frequency-domain averaging (ISFA) is also adopted to further enhance the accuracy of CE. By using the DP-SP based CE scheme, aggregate data rates of 1.87-Gbit/s and 1.57-Gbit/s are experimentally demonstrated over 0.8-m and 2-m indoor free space transmission, respectively, using a commercially available red, green and blue (RGB) light emitting diode (LED) with WDM. Experimental results show that the DP-SP based CE scheme is comparable to the conventional preamble based CE scheme in term of received Q factor and data rate while entailing a much smaller overhead-size.

Pilot-Scale Demonstration of In-Situ Chemical Oxidation ...

Science.gov (United States)

A pilot-scale in situ chemical oxidation (ISCO) demonstration, involving subsurface injections of sodium permanganate (NaMnO4), was performed at the US Marine Corp Recruit Depot (MCRD), site 45 (Parris Island (PI), SC). The ground water was originally contaminated with perchloroethylene (PCE) (also known as tetrachloroethylene), a chlorinated solvent used in dry cleaner operations. High resolution site characterization involved multiple iterations of soil core sampling and analysis. Nested micro-wells and conventional wells were also used to sample and analyze ground water for PCE and decomposition products (i.e., trichloroethyelene (TCE), dichloroethylene (c-DCE, t-DCE), and vinyl chloride (VC)), collectively referred to as chlorinated volatile organic compounds (CVOC). This characterization methodology was used to develop and refine the conceptual site model and the ISCO design, not only by identifying CVOC contamination but also by eliminating uncontaminated portions of the aquifer from further ISCO consideration. Direct-push injection was selected as the main method of NaMnO4 delivery due to its flexibility and low initial capital cost. Site impediments to ISCO activities in the source area involved subsurface utilities, including a high pressure water main, a high voltage power line, a communication line, and sanitary and stormwater sewer lines. Utility markings were used in conjunction with careful planning and judicious selection of injection locations. A

Full Text Available Introduction: To analyze websites quality of catering companies for schools as well as their content in nutrition food education, and to have a first experience with the assessment tool EDALCAT.Material and methods: This is a descriptive cross-sectional study. The study population are the websites of catering companies entrusted with the management of school canteens. The sample was obtained using Google search engine and a ranking of major catering companies financial, choosing those that had websites. Ten websites were selected for a pilot test according to geographic proximity to the city of Alicante and their total revenue. A homemade questionnaire (EDALCAT was designed in order to evaluate the websites. This questionnaire is composed of a block of predictors of quality with 19 variables for reliability, design and navigation; and a second block of specific contents about food education with 19 variables for content and educational activities.Results: Positive results have been obtained in 31 out of 38 questionnaire variables, except for the items: “Search engine”, “Language” (40% and “Help” (10% in the predictors of the quality block; and in the items: “Workshops”, “Recipe book”, “Web nutrition-food” (40% and “Examples” (30% in the specific contents of the food education block. All the evaluated websites exceed 50% of compliance with the quality criteria and with the minimum contents in food education, and only one of them, fails the minimum level of activity established.Conclusions: The predictors of quality and the specific content in food education were successful in all evaluated websites. Most of them got a high score in their assessment, and in their analysis of individual blocks. After the pilot study, EDALCAT questionnaire has been amended and the final EDALCAT has been obtained. Generally speaking, EDALCAT seems appropriate for evaluating the quality of catering companies websites and their content

Full Text Available Background: Providing cooked food to about hundred million children under mid-day meal scheme has been accomplished. Focus has now shifted to delivery of nutrition since the National Food Security Act specifies statutory quantities of protein and calories. Aims & Objectives: Delivery of nutrition requires comprehensive overhaul to include interventions in area of storage, preparation and practices, stoves, human resource development and community participation. Methodology: Based on a baseline survey of 70 schools through random selection in two blocks of Faizabad, Uttar Pradesh these concerns were investigated in details for specific interventions. Results: Nutrition: Both Faizabad and MHRD’s all India data establish that net quantities consumed by a child (quantity served minus plate waste cannot provide prescribed nutrition. It reiterated the fact that mid-day meal is first and major meal for most rural children. Experiments conducted to standardize quantities, consistencies and splitting meal into snack plus meal improved nutritional delivery. Hygiene and food safety: In both blocks food was delivered at high temperature enabling food safety standards to be met with improved hygiene and Standard Operating Procedures (SOPs. Human Resource: A pictorial training manual was prepared to train master trainers as well as cooks. Location specific training using local idiom and practices were used and campaign was conducted to enhance community participation in 45 villages. Fuel efficiency: Low cost smokeless chullahs (stoves designed locally resulted in fuel savings. High efficiency cook stoves were also tested, however their cost limits reproduction. Conclusion: Accomplishing comprehensive improvement within existing cost of conversion per child is a challenge particularly since there are no economies of scale in rural areas. The methodologies created in the pilot for hygiene and food safety, awareness and capacity building through

Full Text Available The aim of this pilot study was to examine if a personalized web-based multi-platform nutrition, exercise, and lifestyle coaching program, supported weight loss and the reduction of chronic disease risk factors in overweight or obese women. Twenty-eight women completed the program, which represented 50% of those who provided baseline data. The program consisted of a one-year curriculum with daily exercise, nutritional habits, and health behaviour lessons along with access to a one-on-one coach. The workouts, habits, and lessons were available via computer, tablet, and mobile device which, along with coaching, facilitated self-monitoring and accountability. At baseline and 12-months, weight, waist circumference, fat mass, muscle mass, blood pressure, total cholesterol, low density lipoproteins, high density lipoproteins, triglycerides, C reactive protein, and fasting glucose were collected. Over the 12 months, women who completed the program, (average age 49.64 (SD 10.99 years, lost 16.52 (SD 13.63 lbs (P < 0.001, and reduced waist circumference by 3.56 (SD 2.31 in (P < 0.0001.

Novel interventions within child care settings are needed for childhood obesity prevention. The aim of this study was to determine the impact of a short-term nutrition education pilot intervention on preschool-age children's snack food choices. Children ages 3-5 years (n = 49) from one child care setting participated in a short-term nutrition education intervention (nine 30-minute interactive lessons) taught over a 2-week period. Pre-post assessments included snack knowledge and snack preference questionnaires and an observed snack selection trial to allow children to choose between a healthy and unhealthy snack choice similar to the current food environment. Children's height and weight were measured and BMI z-scores calculated. Parental reports of demographics and child's food preferences were also collected at baseline. Children significantly improved their preference of healthier snacks (p = 0.03) and the ability to distinguish them (p = 0.03) from other snacks. However, they did not significantly improve (p > 0.05) their snack choice between a healthy and unhealthy choice immediately after the short-term nutrition education program. Children who were younger (p = 0.003) or who had higher nutrition knowledge scores (p = 0.002) were more likely to select the healthy snack after the intervention. This study provides evidence that a short-term nutrition education program improves preschool children's knowledge about healthy snacks, but does not translate to immediate healthier snack selections for all children. Future research should investigate the optimal duration of a nutrition education program in a child care setting and other external influences (parents, policy) most influential on snack choice and eventual obesity risk.

This report describes computational fluid dynamics (CFD) modeling and pilot-scale testing conducted to demonstrate the ability of the Advanced Layered Technology Approach (ALTA) to reduce NO{sub x} emissions in a pulverized coal (PC) boiler. Testing specifically focused on characterizing NO{sub x} behavior with deep burner staging combined with Rich Reagent Injection (RRI). Tests were performed in a 4 MBtu/hr pilot-scale furnace at the University of Utah. Reaction Engineering International (REI) led the project team which included the University of Utah and Combustion Components Associates (CCA). Deep burner staging and RRI, combined with selective non-catalytic reduction (SNCR), make up the Advanced Layered Technology Approach (ALTA) for NO{sub x} reduction. The application of ALTA in a PC environment requires homogenization and rapid reaction of post-burner combustion gases and has not been successfully demonstrated in the past. Operation of the existing low-NO{sub x} burner and design and operation of an application specific ALTA burner was guided by CFD modeling conducted by REI. Parametric pilot-scale testing proved the chemistry of RRI in a PC environment with a NOx reduction of 79% at long residence times and high baseline NOx rate. At representative particle residence times, typical operation of the dual-register low-NO{sub x} burner provided an environment that was unsuitable for NO{sub x} reduction by RRI, showing no NOx reduction. With RRI, the ALTA burner was able to produce NO{sub x} emissions 20% lower than the low-NO{sub x} burner, 76 ppmv vs. 94 ppmv, at a burner stoichiometric ratio (BSR) of 0.7 and a normalized stoichiometric ratio (NSR) of 2.0. CFD modeling was used to investigate the application of RRI for NO{sub x} control on a 180 MW{sub e} wall-fired, PC boiler. A NO{sub x} reduction of 37% from baseline (normal operation) was predicted using ALTA burners with RRI to produce a NO{sub x} emission rate of 0.185 lb/MBtu at the horizontal nose of

There is lack of consensus on how nutritional screening and intervention should be provided to cancer patients. Nutritional screening and support of cancer patients are not well established in the Middle East. We report our systematic and practical experience led by a qualified specialist dietician in a cancer inpatient setting, using a novel nutritional screening tool. Ninety-seven consecutive inpatients underwent nutritional screening and categorised into three nutritional risk groups based on oral intake, gastrointestinal symptoms, body mass index (BMI) and weight loss. Nutritional support was introduced accordingly. Statistical tests used included ANOVA, Bonferroni post hoc, chi-square and log rank tests. Median age was 48 (19-87)years. Patients were categorised into three nutritional risk groups: 55 % low, 37 % intermediate and 8 % high. Nutritional intervention was introduced for 36 % of these patients. Individually, weight, BMI, oral intake, serum albumin on admission and weight loss significantly affected nutritional risk and nutritional intervention (all significant P values). Eighty-seven, 60 and 55 % of patients admitted for chemotherapy, febrile neutropenia and other reasons, respectively, did not require specific nutritional intervention. There was a statistically significant relationship between nutritional risk and nutritional intervention (P=0.005). Significantly more patients were alive at 3 months in low (91 %) than intermediate (75 %) than high (37 %)-risk groups. About a third of cancer inpatients require nutritional intervention. The adopted nutritional risk assessment tool is simple and practical. The validity of this tool is supported by its significant relation with known individual nutritional risk factors. This should be confirmed in larger prospective study and comparing this new tool with other established ones.

Two mass interventions in the local low energy-density diet were evaluated for safety, acceptability and nutritional efficacy in a four-group matched study of 896 Papua New Guinea children aged 12-54 months. A single dose of 125 mg of pyrantel pamoate and an 800 mg supply of red palm oil were given monthly at the regular child health clinics. Both were safe and highly accepted. Children given palm oil gained more weight than controls (P less than .05) in the first three study months, confirming a pilot study. However, weight gain after one year was 94% of standard, with no differences in anthropometry, morbidity or mortality between groups. The lack of demonstrable differences at one year is attributed to secular improvement in control group nutrition and to diffusion of palm oil supplies within the family. While pyrantel was an effective antihelminthic, further study is needed to define the nutritional role of mass worm treatment. Palm oil was economical and culturally popular; thus it should be an ideal import substitution. It is clinically useful where diets are of low energy-density. However, any simultaneous demonstration of its nutritional safety, acceptability as a sustained mass intervention must be carried out in an area where major child growth deficits remain and expropriation of the oil by other household members can be controlled.

García de Diego, Laura; Cuervo, Marta; Martínez, J Alfredo

2015-01-01

Computer assisted instruction (CAI) is an effective tool for evaluating and training students and professionals. In this article we will present a learning-oriented CAI, which has been developed for students and health professionals to acquire and retain new knowledge through the practice. A two-phase pilot evaluation was conducted, involving 8 nutrition experts and 30 postgraduate students, respectively. In each training session, the software developed guides users in the integral evaluation of a patient's nutritional status and helps them to implement actions. The program includes into the format clinical tools, which can be used to recognize possible patient's needs, to improve the clinical reasoning and to develop professional skills. Among them are assessment questionnaires and evaluation criteria, cardiovascular risk charts, clinical guidelines and photographs of various diseases. This CAI is a complete software package easy to use and versatile, aimed at clinical specialists, medical staff, scientists, educators and clinical students, which can be used as a learning tool. This application constitutes an advanced method for students and health professionals to accomplish nutritional assessments combining theoretical and empirical issues, which can be implemented in their academic curriculum.

Full Text Available Objective. Early childhood development (ECD programs have demonstrated drastic improvements in survival, growth, health, and social productivity. An ECD pilot intervention was delivered to vulnerable populations of a Women, Infants, and Children (WIC clinic in Des Moines, Iowa, to assess ECD outcomes and parental receivability in this setting. Study Design. In a randomized, single blinded control initiative, WIC group sessions of mothers (children aged 2 years and younger were selected for pilot ECD intervention (37 participants or control (36. Care for Child Development ECD course material was supplemented to intervention groups. Survey results were assessed with paired samples T-testing and by an ANOVA. Results. Pilot session receivability demonstrated significance in all areas relative to control: enjoyment, p=0.008; learning capacity, p=0.011; and participant sharing, p=0.023. Furthermore, the previously validated ECD intervention demonstrated significantly improved cumulative 1 month behavior outcomes following the intervention: p=0.006. Conclusions. The WIC setting provides an ideal environment for delivering ECD education beyond traditional counseling in nutrition. High receivability indices among parents demonstrate remarkable capacity for improvement and growth. The significance in receivability, as well as 1 month behavior outcomes, represents parents’ overall readiness to enhance the home environment for their child if merely educated how.

The benefits of wholegrain finger millet and sorghum were combined with that of fructan in form of fructoligosaccharide in the pilot-scale production (10 kg) of cookies. Complete nutritional analysis of the cookies was carried out to provide nutritional information to the consumers. Whole-multigrain cookies with fructan can be categorized as "High Fiber" as they suffice 21% daily value (DV) of fiber and a "Good Source" of iron as they suffice 12.8% DV of iron. A total of 300 consumers (M=110 and F=190), aged between 8 and 66 y evaluated cookies. The overall acceptability (OAA) score of 300 consumers was 8.0±0.58 on a 9-point hedonic scale. Females rated cookies significantly (Pconsumers signified ample scope for viability and marketability of cookies at the commercial scale.   Consumers are looking at snack and convenience foods to provide increased fiber in their diet and there is a tremendous interest in low-calorie and low-sugar foods. The demand of whole and multigrain products is also on the rise because of the Government's emphasis. The present study would assist in assessing feasibility of commercial production of such novel health foods. Together with this, it will ascertain the marketability and commercial viability of the product by means of the consumer preference trials. Availability of such cookies in the market would offer consumers "health" with "convenience" and "taste."

This study was performed to assess oral and nutritional status of nursing home residents in a region of Lower Saxony, Germany. The aim was to show potential associations between oral status (dentate or edentulous), further anamnestic factors (dementia, age, smoking) and the risk for malnutrition in this population. In this observational cross-sectional pilot study of residents from four nursing homes Mini Nutritional Assessment (MNA), Body-Mass-Index (BMI), dental status (DMF-T) and periodontal situation (PSR ® /PSI) were recorded. Associations of recorded factors with oral health and nutritional status were examined in univariate and multivariate analysis. Eighty-seven residents participated in the study (mean age: 84.1 years; female: 72%, demented: 47%). Average BMI was 26.2 kg/m 2 ; according MNA 52% were at risk for malnutrition. 48% of the residents were edentulous, and the average DMF-T of dentulous was 25.0 (3.7) (D-T: 2.0 [3.1], M-T: 15.0 [8.3], F-T: 8.0 [7.4]); PSR ® /PSI 3 and 4 (need for periodontal treatment) showed 79% of residents. In univariate analysis dementia (OR 2.5 CI 95 1.1-5.6) but not being edentulous (OR 2.0 CI 95 0.8-5.8) were associated with being at risk for malnutrition. Dementia remained associated in multivariate analysis adjusting for age and sex, (OR 3.1 CI 95 1.2-8.2) and additionally being edentulous (OR 2.8 CI 95 1.1-7.3) became associated significantly. Furthermore, nursing home residents with dementia had more remaining teeth (OR 2.5 CI 95 1.1-5.9). Dementia was a stronger predictor for risk of malnutrition in nursing home residents than being edentulous. Further studies to elucidate the possible role of oral health as cofactor for malnutrition in dementia are needed.

Arsenic contamination of drinking water poses serious health risks to millions of people worldwide. To reduce such risks, the United States Environmental Protection Agency recently lowered the Maximum Contaminant Level for arsenic in drinking water from 50 to 10 microgL(-1). The majority of water systems requiring compliance are small systems that serve less than 10,000 people. Current technologies used to clean arsenic-contaminated water have significant drawbacks, particularly for small treatment systems. In this pilot-scale demonstration, we investigated the use of arsenic-hyperaccumulating ferns to remove arsenic from drinking water using a continuous flow phytofiltration system. Over the course of a 3-month demonstration period, the system consistently produced water having an arsenic concentration less than the detection limit of 2 microgL(-1), at flow rates as high as 1900 L day(-1) for a total treated water volume of approximately 60,000 L. Our results demonstrate that phytofiltration provides the basis for a solar-powered hydroponic technique to enable small-scale cleanup of arsenic-contaminated drinking water.

DNA damage can be considered as a biomarker for toxicity and response to chemotherapy. It is not known whether the chemotherapy-induced genotoxicity is associated with malnutrition. In this pilot study, we assess genotoxicity by means of DNA damage in patients with lymph-node positive colorectal cancer (CRC) and explore associations with chemotherapy treatment and nutritional status. DNA damage was compared between patients receiving chemotherapy (n = 24) and those not receiving chemotherapy (n = 20). DNA damage was measured in frozen whole blood by the comet assay. Associations between DNA damage and various indicators of malnutrition were also explored, including Patient-Generated Subjective Global Assessment (PG-SGA), bioelectrical impedance analysis (BIA) and anthropometric measurements, using multiple linear regression models. Patients on chemotherapy have higher levels of DNA damage in blood cells than patients not receiving chemotherapy (median of 16.9 and 7.9% tail DNA respectively, p = 0.001). The moderately malnourished patients (PG-SGA category B), representing 41% of the patients, have higher levels of cellular DNA damage than patients with good nutritional status (mean difference of 7.5% tail DNA, p = 0.033). In conclusion, adjuvant chemotherapy and malnutrition are both associated with increased levels of DNA damage in blood cells of CRC patients. Carefully controlled longitudinal studies or randomized controlled trials should be performed to determine whether good nutritional status may protect against chemotherapy-induced genotoxicity and enhance compliance to therapy in CRC patients.

Kupolati, Mojisola D; MacIntyre, Una E; Gericke, Gerda J

2018-01-01

Background: A theory-based contextual nutrition education manual (NEM) may enhance effective teaching of nutrition in schools. School nutrition education should lead to the realization of such benefits as improved health, scholarly achievement leading to manpower development and consequently the nation's development. The purpose of the study was to develop a contextual NEM for teachers of Grade 5 and 6 learners in the Bronkhorstspruit district, South Africa, and to assess teachers' perception on the use of the manual for teaching nutrition. Methods: This descriptive case study used an interpretivist paradigm. The study involved teachers ( N = 6) who taught nutrition in Life Skills (LS) and Natural Science and Technology (NST) in a randomly selected primary school in the Bronkhorstspruit district. Findings from a nutrition education needs assessment were integrated with the constructs of the Social cognitive theory (SCT) and the Meaningful learning model (MLM) and the existing curriculum of the Department of Basic Education (DoBE) to develop a contextual NEM. The manual was used by the teachers to teach nutrition to Grades 5 and 6 learners during the 2015 academic year as a pilot project. A focus group discussion (FDG) was conducted with teachers to gauge their perceptions of the usefulness of the NEM. Data were analyzed using the thematic approach of the framework method for qualitative research. Results: Teachers described the NEM as rich in information, easy to use and perceived the supporting materials and activities as being effective. The goal setting activities contained in the NEM were deemed to be ineffective. Teachers felt that they did not have enough time to teach all the important things that the learners needed to know. Conclusion: Teachers perceived the NEM as helpful toward improving their nutrition teaching skills.The NEM template may furthermore guide teachers in planning theory-based nutrition lessons.

Wobser, J.K.

1983-01-01

The Alpha-Contained Decontamination and Disassembly (AD and D) pilot facility was designed to demonstrate the process flowsheet under conditions typical to those expected in a production facility. To achieve this, nonradioactive waste items similar to those in retrievable storage at the Savannah River Plant burial ground (e.g. gloveboxes), were chemically sprayed and size reduced. During process runs, parameters such as feed rate, oxide removal, etching rate, and secondary waste generation were determined. The exhaust system was monitored during operation to ensure that exhaust from the facility was sufficiently filtered before release to the atmosphere. The strategy for decontamination techniques required development during the nonradioactive testing period. Under investigation during process runs were both once-through and recirculating washes, and their correlation to oxide removal and etching rates on the stainless steel feed items. Wash products of the decontamination process were analyzed for concentration of Ni, Cr, Fe, Mn, and Si, major components of stainless steel. Size reduction techniques were also developed during the nonradioactive testing period. An array of conventional power and pneumatic tools were tested and evaluated. Plasma arc torch operating parameters; standoff distance, ampere setting, and cutting angle were determined

The goal of point-of-purchase (POP) nutrition information is to help consumers make informed, healthful choices. Despite limited evaluation, these population-based approaches are being advocated to replace traditional, more expensive, individual behavior-change strategies. Few studies have examined the effect of POP information on buying patterns of college students, a group with high obesity rates and poor eating habits. This quasi-experimental pilot project sought to determine whether the "Eat Smart" POP program affected food-purchasing habits of multiethnic college students shopping at an on-campus convenience store. Baseline sales data of foods in the cereal, soup, cracker, and bread categories were collected for 6 weeks during Fall 2008. After Winter break, a few food items within each of these food categories were labeled as healthful using a "Fuel Your Life" shelf tag, and sales data were then collected for 5 weeks. In each of the four food categories, nontagged foods were available at the identical price as tagged items. Following intervention, there were increased sales of tagged items (measured as a percentage of total sales) in the cereal, soup, and cracker categories, while sales of bread decreased. Although none of these changes were statistically significant, the intervention resulted in a 3.6%±1.6% (P=0.082) increase in the percentage of sales from tagged items. Thus, providing POP nutrition information in a college campus convenience store may promote healthful food choices. A longer study examining the effect of POP on sales of items in other food categories is warranted. Copyright © 2011 American Dietetic Association. Published by Elsevier Inc. All rights reserved.

The Integrated DWPF Melter System (IDMS), operated by the Savannah River Laboratory, is a pilot scale facility used in support of the start-up and operation of the Department of Energy's Defense Waste Processing Facility. The IDMS has successfully demonstrated, on an engineering scale (one-fifth), that simulated high level radioactive waste (HLW) sludge can be chemically treated with formic acid to adjust both its chemical and physical properties, and then blended with simulated precipitate hydrolysis aqueous (PHA) product and borosilicate glass frit to produce a melter feed which can be processed into a durable glass product. The simulated sludge, PHA and frit were blended, based on a product composition program, to optimize the loading of the waste glass as well as to minimize those components which can cause melter processing and/or glass durability problems. During all the IDMS demonstrations completed thus far, the melter feed and the resulting glass that has been produced met all the required specifications, which is very encouraging to future DWPF operations. The IDMS operations also demonstrated that the volatile components of the melter feed (e.g., mercury, nitrogen and carbon, and, to a lesser extent, chlorine, fluorine and sulfur) did not adversely affect the melter performance or the glass product

Thermal desorption is an innovative technology that has seen significant growth in applications to organically contaminated soils and sludges for the remediation of hazardous, radioactive and mixed waste sites. This paper will present the results of a bench and pilot-scale demonstration of this technology for the removal of mercury from the Lower East Fork Poplar Creek floodplain soil. Results demonstrate that the mercury in this soil can be successfully removed to the target treatment levels of 10 milligrams per kilogram (mg/kg) and that all process residuals could be rendered RCRA-nonhazardous as defined by the Resource Conservation and Recovery Act. Sampling and analyses of the desorber off-gas before and after the air pollution control system demonstrated effective collection of mercury and organic constituents. Pilot-scale testing was also conducted to verify requirements for material handling of soil into and out of the process. This paper will also present a conceptual design and preliminary costs of a full-scale system, including feed preparation, thermal treatment, and residuals handling for the soil

The weather information requirements for pilots and the deficiencies of the current aviation weather support system in meeting these requirements are defined. As the amount of data available to pilots increases significantly in the near future, expert system technology will be needed to assist pilots in assimilating that information. Some other desirable characteristics of an automation-assisted system for weather data acquisition, dissemination, and assimilation are also described.

Full Text Available Background: Rational nutrition management in infants under 3 years is an important part of their adequate development at this age and in future.Objective: Our aim was to evaluate awareness of pediatricians and parents concerning rational nutrition management in infants under 3 years.Methods: 300 pediatricians and 300 parents of infants under 3 years who live in Moscow, Ivanovo, and Yaroslavl were enrolled in pilot survey.Results: Pediatricians' recommendations on child nutrition management satisfied the majority of parents (252; 84%, however, less than half of families (135; 45% followed them. In other cases the child's ration depended on mother's opinion on the matter (96; 32% and on child's food preference. «Unhealthy» food such as groceries and provision, processed food, spices, seafood, fast food, chocolate, candies, and sweets as well as soda was included in child's ration at the age of 2 and its consumption frequency increased significantly at the age of 3. Pediatricians strongly recommended special dairy for infants from the age of 1 (known as the 3rd formula. In fact, only half of children in Moscow eat them, and 27–30% of children in Ivanovo and Yaroslavl.Conclusion: Harmful breach of nutrition management in infants under 3 years is detected. Evidently, parents are not competent on the question. Optimization of educational activities performed by pediatricians, medical stuff, and mass media is required.

Nutrition is important for pressure ulcer prevention. This randomised control pilot study assessed the feasibility of conducting a larger trial to test the effectiveness of a patient-centred intervention for improving the dietary intakes of patients at risk of pressure ulcer in hospital. A 3-day intervention targeting patients at risk of pressure ulcer was developed, based on three main foundations: patient education, patient participation and guided goal setting. The intervention was piloted in three wards in a metropolitan hospital in Queensland, Australia. Participants were randomised into control or intervention groups and had their oral intakes monitored. A subset of intervention patients was interviewed on their perceptions of the intervention. Feasibility was tested against three criteria: ≥75% recruitment; ≥80% retention; and ≥80% intervention fidelity. Secondary outcomes related to effects on energy and protein intakes. Eighty patients participated in the study and 66 were included in final analysis. The recruitment rate was 82%, retention rate was 88%, and 100% of intervention patients received the intervention. Patients viewed the intervention as motivating and met significantly more of their estimated energy and protein requirements over time. This pilot study indicates that the intervention is feasible and acceptable by patients at risk of pressure ulcer. A larger trial is needed to confirm the effectiveness of the intervention in the clinical setting. © 2015 Nordic College of Caring Science.

Objectives To investigate the impact of implant-prosthetic rehabilitation combined with nutritional counseling on the nutritional status of patients with severely reduced dentitions. Design An explorative intervention study including an intra-individual comparison of 20 patients with severely reduced dentitions in terms of nutrition- and quality of life-related parameters recorded at baseline and at six and twelve months after implant-prosthetic rehabilitation. Participants Twenty patients from the Department of Prosthetic Dentistry of Justus-Liebig University of Giessen, with an mean age of 63 years, who had fewer than ten pairs of antagonists. Measurements The baseline data collection included dental status, a chewing ability test, laboratory parameters, anthropometric data (body mass index), energy supply, a 3-day dietary record, an analysis of the oral health-related quality of life (OHRQoL) with the OHIP-G14, the Mini-Mental Status (MMS) and Mini Nutritional Assessment (MNA). Six months after implantation and prosthetic rehabilitation, individual nutritional counseling was performed by a dietician. Data were again collected and analyzed. A final follow-up was conducted 12 months after prosthetic rehabilitation. Results Despite the highly significant improvement in masticatory ability and OHRQoL after implant-prosthetic rehabilitation, no significant changes were observed regarding MNA, anthropometric data or energy supply. Except for cholinesterase (p = 0.012), ferritin (p = 0.003), folic acid (p = 0.019) and vitamin A (p = 0.004), no laboratory parameter changed significantly during the investigation period. In addition, no general significant differences were observed for nutrient intake or food choice. Conclusion The present study does not confirm the assumption that the implant-prosthetic rehabilitation of patients with severely reduced residual dentitions with or without an individual nutritional counseling influences nutritional status.

Accelerator driven sub-critical reactors are subject of many research programmes since more than ten years, with the aim of testing the feasibility of the concept as well as their efficiency as a transmutation tool. Several key points like the accelerator, the spallation target, or neutronics in a subcritical medium were investigated extensively these last years, allowing for technological choices and the design of a low power European demonstration ADS (a few tens of MWth). Programmes dedicated to subcritical reactor piloting proposed a monitoring procedure to be validated in forthcoming experiments. Accelerator R and D provided the design of a LINAC for an ADS and research work on accelerator reliability is going on. A spallation target was operated at PSI and the design of a windowless target is in progress. All this research work converges to the design of a European demonstration ADS, the ETD/XT-ADS, which could be the Belgian MYRRHA project. (author)

Forty-four cases of different untreated gastrointestinal tumors were studied with regard to cell kinetic activity. As a pilot experiment, the authors also determined the 3H-TdR Labeling Index (LI) in 28 patients in basal conditions and after 15 days of nutritional manipulation with prevalently lipid-based or glucose-based feeding to ascertain whether selective nutritional regimens could affect tumor proliferation. Preliminary results from this study indicate that a kinetic perturbation is induced in tumor cells by nutritional manipulation. Lipid-based feeding seems to produce effects similar to those of chemical or physical anticancer agents, thus suggesting a possible supporting role of nutritional manipulation in cancer treatment strategy

1992-01-01

The Defense Waste Processing Facility (DWPF) has been designed and constructed to immobilize Savannah River Site high level liquid waste within a durable borosilicate glass matrix for permanent storage. The DWPF will be operated to produce a glass product which must meet a number of product property constraints which are dependent upon the final product composition. During actual operations, the DWPF will control the properties of the glass product by the controlled blending of the waste streams with a glass-forming frit to produce the final melter feed slurry. The DWPF will verify control of the glass product through analysis of vitrified samples of slurry material. In order to demonstrate the DWPF process control and product verification strategy, a pilot-scale vitrification research facility was operated in three discrete batches using simulated DWPF waste streams. All of the DWPF process control methodologies were followed and the glass produce from each experiment was leached according to the Product Consistency Test. Results of the campaign are summarized

Nutritional status may influence quality of life and prognosis among pancreatic cancer patients, yet few studies describe measures of nutritional status during treatment. We evaluated the nutritional status of locally advanced pancreatic cancer (LAPC) patients undergoing chemoradiotherapy who received baseline nutritional assessment and counseling. Fourteen newly diagnosed LAPC patients enrolled in phase I/II trials of capecitabine with concomitant radiotherapy were assessed for baseline clinical nutrition measures (body mass index, albumin, weight loss, total energy, and protein intake). Participants completed the Anorexia/Cachexia Subscale (A/CS) questionnaire at baseline and during the 6 weeks of treatment. We evaluated associations between baseline characteristics and subsequent A/CS scores with linear regression and changes in A/CS were assessed with the paired t test. We observed a statistically significant increase in mean A/CS between baseline [24.9, standard deviation (SD) = 9.7] and end of treatment (29.9, SD = 6.2). Controlling for baseline A/CS score, only weight loss greater than 5% of body weight over 1 month was associated with A/CS scores at 6 weeks (β = 10.558, standard error = 3.307, p value = 0.009) and mean A/CS scores during the last 3 weeks of treatment (β = 12.739, standard error = 2.251, p value = 0.001). After 6 weeks of chemoradiotherapy, LAPC patients reported a statistically significant improvement in appetite and weight concerns. Increases in AC/S scores were associated with higher baseline A/CS scores and weight loss of 5% or more during 1 month. Further research is needed to determine the impact of nutritional support during treatment, as improvements in this domain may impact LAPC patients' overall quality of life.

In 2013, the Nutrition for Growth Summit called for a Global Nutrition Report (GNR) to strengthen accountability in nutrition so that progress in reducing malnutrition could be accelerated. This article summarizes the results of the first GNR. By focusing on undernutrition and overweight, the GNR puts malnutrition in a new light. Nearly every country in the world is affected by malnutrition, and multiple malnutrition burdens are the “new normal.” Unfortunately, the world is off track to meet the 2025 World Health Assembly (WHA) targets for nutrition. Many countries are, however, making good progress on WHA indicators, providing inspiration and guidance for others. Beyond the WHA goals, nutrition needs to be more strongly represented in the Sustainable Development Goal (SDG) framework. At present, it is only explicitly mentioned in 1 of 169 SDG targets despite the many contributions improved nutritional status will make to their attainment. To achieve improvements in nutrition status, it is vital to scale up nutrition programs. We identify bottlenecks in the scale-up of nutrition-specific and nutrition-sensitive approaches and highlight actions to accelerate coverage and reach. Holding stakeholders to account for delivery on nutrition actions requires a well-functioning accountability infrastructure, which is lacking in nutrition. New accountability mechanisms need piloting and evaluation, financial resource flows to nutrition need to be made explicit, nutrition spending targets should be established, and some key data gaps need to be filled. For example, many UN member states cannot report on their WHA progress and those that can often rely on data >5 y old. The world can accelerate malnutrition reduction substantially, but this will require stronger accountability mechanisms to hold all stakeholders to account. PMID:25740908

Draft plan for the Waste Isolation Pilot Plant test phase: Performance assessment and operations demonstration

International Nuclear Information System (INIS)

1989-04-01

The mission of the Waste Isolation Pilot Plant (WIPP) Project is to provide a research and development facility to demonstrate the safe disposal of transuranic (TRU) radioactive wastes resulting from United States defense programs. With the Construction Phase of the WIPP facility nearing completion, WIPP is ready to initiate the next phase in its development, the Test Phase. The purpose of the Test Phase is to collect the necessary scientific and operational data to support a determination whether to proceed to the Disposal Phase and thereby designate WIPP a demonstration facility for the disposal of TRU wastes. This decision to proceed to the Disposal Phase is scheduled for consideration by September 1994. Development of the WIPP facility is the responsibility of the United States Department of Energy (DOE), whose Albuquerque Operations Office has designated the WIPP Project Office as Project Manager. This document describes the two major programs to be conducted during the Test Phase of WIPP: (1) Performance Assessment for determination of compliance with the Environmental Protection Agency Standard and (2) Operations Demonstration for evaluation of the safety and effectiveness of the DOE TRU waste management system's ability to emplace design throughput quantities of TRU waste in the WIPP facility. 42 refs., 38 figs., 14 tabs

This study was conducted to evaluate the feasibility of a sodium reduction program at local restaurants through nutrition education and examination of the health of restaurant owners and cooks. The study was a single-arm pilot intervention using a pre-post design in one business district with densely populated restaurants in Seoul, South Korea. The intervention focused on improving nutrition behaviors and psychosocial factors through education, health examination, and counseling of restaurant personnel. Forty-eight restaurant owners and cooks completed the baseline survey and participated in the intervention. Forty participants completed the post-intervention survey. The overweight and obesity prevalences were 25.6% and 39.5%, respectively, and 74.4% of participants had elevated blood pressure. After health examination, counseling, and nutrition education, several nutrition behaviors related to sodium intake showed improvement. In addition, those who consumed less salt in their baseline diet (measured with urine dipsticks) were more likely to agree that providing healthy foods to their customers is necessary. This study demonstrated the potential to reduce the sodium contents of restaurant foods by improving restaurant owners' and cooks' psychological factors and their own health behaviors. This small pilot study demonstrated that working with restaurant owners and cooks to improve their own health and sodium intake may have an effect on participation in restaurant-based sodium reduction initiatives. Future intervention studies with a larger sample size and comparison group can focus on improving the health and perceptions of restaurant personnel in order to increase the feasibility and efficacy of restaurant-based sodium reduction programs and policies.

The incidence of malnutrition in hospitalized patients is relatively high (up to 55%) despite breakthroughs in nutrition support therapies. These patients have increased morbidity and mortality, extended hospital stays, and care that is associated with higher costs. These patients are often poorly managed due to inadequate nutrition assessment and poor medical knowledge and practice in the field of nutrition. Nutrition support teams (NSTs) are interdisciplinary support teams with specialty training in nutrition that are often comprised of physicians, dietitians, nurses, and pharmacists. Their role includes nutrition assessment, determination of nutrition needs, recommendations for appropriate nutrition therapy, and management of nutrition support therapy. Studies have demonstrated significant improvements in patient nutrition status and improved clinical outcomes as well as reductions in costs when patients were appropriately managed by a multispecialty NST vs individual caregivers. Despite this, there has been steady decline in the number of formal NST in recent years (65% of hospitals in 1995 to 42% in 2008) as hospitals and other healthcare organizations look for ways to cut costs. Given the importance of nutrition status on clinical outcomes and overall healthcare costs, a number of institutions have introduced and sustained strong nutrition training and support programs and teams, demonstrating both clinical and economic benefit. The benefits of NST, training and implementation strategies, and tips for justifying these clinically and economically beneficial groups to healthcare organizations and governing bodies are discussed in this review.

The number of pregnant women with a body mass index (BMI) of 30kg/m(2) or more is increasing, which has important implications for antenatal care. Various resource-intensive interventions have attempted to assist women in managing their weight gain during pregnancy with limited success. A mobile phone app has been proposed as a convenient and cost-effective alternative to face-to-face interventions. This paper describes the process of developing and pilot testing the Eating4Two app, which aims to provide women with a simple gestational weight gain (GWG) calculator, general dietary information, and the motivation to achieve a healthy weight gain during pregnancy. The project involved the development of app components, including a graphing function that allows the user to record their weight throughout the pregnancy and to receive real-time feedback on weight gain progress and general information on antenatal nutrition. Stakeholder consultation was used to inform development. The app was pilot tested with 10 pregnant women using a mixed method approach via an online survey, 2 focus groups, and 1 individual interview. The Eating4Two app took 7 months to develop and evaluate. It involved several disciplines--including nutrition and dietetics, midwifery, public health, and information technology--at the University of Canberra. Participants found the Eating4Two app to be a motivational tool but would have liked scales or other markers on the graph that demonstrated exact weight gain. They also liked the nutrition information; however, many felt it should be formatted in a more user friendly way. The Eating4Two app was viewed by participants in our study as an innovative support system to help motivate healthy behaviors during pregnancy and as a credible resource for accessing nutrition-focused information. The feedback provided by participants will assist with refining the current prototype for use in a clinical intervention trial.

Malnutrition is common in patients on hemodialysis (prevalence of 30% to 50%) and is associated with higher mortality. Lean body mass (LBM) assessment is an accurate way of assessing nutritional status. The dual-energy X-ray absorptiometry (DEXA) scan is a reliable method in assessing body compositions and LBM; however, it is expensive and largely inaccessible. Anthropometric skinfold thickness measurement (ASFM) is useful in assessing LBM. It is cheaper and accessible, but underutilized clinically. The subjective global score (SGA) is a well-established method of assessing nutritional status. All three methods of assessing nutritional status were compared. In this pilot observational study, there was a significant correlation between LBM% estimated by DEXA and ASFM (mean difference -1.46% [95% CI -4.09 to 1.18]; LOA -14.0 to 11.1). Nutritional status by SGA could only detect those severely malnourished when using LBM% by ASFM as comparison. Our study demonstrated that ASFM is a useful method of assessing LBM and nutritional status, which can be easily utilized clinically. Copyright© by the American Nephrology Nurses Association.

The objective of this project was to explore the effort necessary to transform the Older Americans Act Nutrition Program (OAANP) into core programs within an integrated health care delivery system that serves hospital-discharged older adults in order to assist them in reintegrating into the community. Six OAANPs in six states were funded and provided technical assistance to develop coalitions with hospitals and community organizations. Each demonstration site was unique and faced many challenges in reaching out to a hospitalized vulnerable population. This project also provided opportunities to try out new initiatives and examine their sustainability within the community.

2006-01-01

This pilot study examined nutrition-related attitudes that may affect food choices at fast-food restaurants, including consumer attitudes toward nutrition labeling of fast foods and elimination of value size pricing. A convenience sample of 79 fast-food restaurant patrons aged 16 and above (78.5% white, 55% female, mean age 41.2 [17.1]) selected meals from fast-food restaurant menus that varied as to whether nutrition information was provided and value pricing included and completed a survey and interview on nutrition-related attitudes. Only 57.9% of participants rated nutrition as important when buying fast food. Almost two thirds (62%) supported a law requiring nutrition labeling on restaurant menus. One third (34%) supported a law requiring restaurants to offer lower prices on smaller instead of bigger-sized portions. This convenience sample of fast-food patrons supported nutrition labels on menus. More research is needed with larger samples on whether point-of-purchase nutrition labeling at fast-food restaurants raises perceived importance of nutrition when eating out.

To review and discuss the evidence and arguments to combine enteral nutrition and parenteral nutrition in the ICU, in particular with reference to the Early Parenteral Nutrition Completing Enteral Nutrition in Adult Critically Ill Patients (EPaNIC) study. The EPaNIC study shows an advantage in terms of discharges alive from the ICU when parenteral nutrition is delayed to day 8 as compared with combining enteral nutrition and parenteral nutrition from day 3 of ICU stay. The difference between the guidelines from the European Society of Enteral and Parenteral Nutrition in Europe and American Society for Parenteral and Enteral Nutrition/Society of Critical Care Medicine in North America concerning the combination of enteral nutrition and parenteral nutrition during the initial week of ICU stay was reviewed. The EPaNIC study clearly demonstrates that early parenteral nutrition in the ICU is not in the best interests of most patients. Exactly at what time point the combination of enteral nutrition and parenteral nutrition should be considered is still an open question.

Perceptions of masculinity and femininity influence behaviors and can be identified in young children and adolescents (Brannon, 2004). Thus, adolescents' engagement in health risk or promoting behaviors is influenced by perceptions of masculinity and femininity and the differences in expectations, norms and responsibilities for girls and boys (WHO, 2007). Girls and boys have different needs, and gender-based interventions that consider similarities as well as differences are needed. A gender-based nutrition and sexual health promotion program was developed and piloted by the Philadelphia Ujima Coalition in a high school setting. To explore the gender differences in adolescents' perceptions of the influence of gender norms on weight, nutrition, physical activity, and sexual health and the implication of these differences in future gender-integrated health promotion programming for youth, a content analysis of student and facilitator debriefing forms were implemented for the participating schools. The content analysis was used to identify central themes, concepts gained, and overall impact of the intervention sessions. Overall, gender norms influence healthy eating practices and activity through influencing perceptions of body type in adolescents. Gender norms also influence sexual activity and decision making through influencing perceptions of beauty, masculinity, femininity, pressures and popular concepts related to sexual activity. Thus, interventions that address gender may more effectively promote health and wellness in adolescents. Copyright © 2014 Elsevier Ltd. All rights reserved.

Poor nutrition in the first months after oesophago-gastric resection is a contributing factor to the reduced quality of life seen in these patients. The aim of this pilot and feasibility study was to ascertain the feasibility of conducting a multi-centre randomised controlled trial to evaluate routine home enteral nutrition in these patients. Patients undergoing oesophagectomy or total gastrectomy were randomised to either six weeks of home feeding through a jejunostomy (intervention), or treatment as usual (control). Intervention comprised overnight feeding, providing 50 % of energy and protein requirements, in addition to usual oral intake. Primary outcome measures were recruitment and retention rates at six weeks and six months. Nutritional intake, nutritional parameters, quality of life and healthcare costs were also collected. Interviews were conducted with a sample of participants, to ascertain patient and carer experiences. Fifty-four of 112 (48 %) eligible patients participated in the study over the 20 months. Study retention at six weeks was 41/54 patients (76 %) and at six months was 36/54 (67 %). At six weeks, participants in the control group had lost on average 3.9 kg more than participants in the intervention group (95 % confidence interval [CI] 1.6 to 6.2). These differences remained evident at three months (mean difference 2.5 kg, 95 % CI -0.5 to 5.6) and at six months (mean difference 2.5 kg, 95 % CI -1.2 to 6.1). The mean values observed in the intervention group for mid arm circumference, mid arm muscle circumference, triceps skin fold thickness and right hand grip strength were greater than for the control group at all post hospital discharge time points. The economic evaluation suggested that it was feasible to collect resource use and EQ-5D data for a full cost-effectiveness analysis. Thematic analysis of 15 interviews identified three main themes related to the intervention and the trial: 1) a positive experience, 2) the reasons for taking

There are many challenges in developing effective and integrated catchment management solutions for hydrology and water quality issues. Such solutions should ideally build on current scientific evidence to inform policy makers and regulators and additionally allow stakeholders to take ownership of local and/or national issues, in effect bringing together ‘communities of practice’. A strategy being piloted in the UK as the Pilot Virtual Observatory (pVO), funded by NERC, is to demonstrate the use of cyber-infrastructure and cloud computing resources to investigate better methods of linking data and models and to demonstrate scenario analysis for research, policy and operational needs. The research will provide new ways the scientific and stakeholder communities come together to exploit current environmental information, knowledge and experience in an open framework. This poster presents the project scope and methodologies for the pVO work dealing with national modelling of hydrology and macro-nutrient biogeochemistry. We evaluate the strategies needed to robustly benchmark our current predictive capability of these resources through ensemble modelling. We explore the use of catchment similarity concepts to understand if national monitoring programs can inform us about the behaviour of catchments. We discuss the challenges to applying these strategies in an open access and integrated framework and finally we consider the future for such virtual observatory platforms for improving the way we iteratively improve our understanding of catchment science.

Photocatalytic water splitting with solar light is one of the most promising technologies for solar hydrogen production. From a systematic point of view, whether it is photocatalyst and reaction system development or the reactor-related design, the essentials could be summarized as: photon transfer limitations and mass transfer limitations (in the case of liquid phase reactions). Optimization of these two issues are therefore given special attention throughout our study. In this review, the state of the art for the research of photocatalytic hydrogen production, both outcomes and challenges in this field, were briefly reviewed. Research progress of our lab, from fundamental study of photocatalyst preparation to reactor configuration and pilot level demonstration, were introduced, showing the complete process of our effort for this technology to be economic viable in the near future. Our systematic and continuous study in this field lead to the development of a Compound Parabolic Concentrator (CPC) based photocatalytic hydrogen production solar rector for the first time. We have demonstrated the feasibility for efficient photocatalytic hydrogen production under direct solar light. The exiting challenges and difficulties for this technology to proceed from successful laboratory photocatalysis set-up up to an industrially relevant scale are also proposed. These issues have been the object of our research and would also be the direction of our study in future. (author)

NSTAR Electric & Gas Corporation (“the Company”, or “NSTAR”) developed and implemented a Smart Grid pilot program beginning in 2010 to demonstrate the viability of leveraging existing automated meter reading (“AMR”) deployments to provide much of the Smart Grid functionality of advanced metering infrastructure (“AMI”), but without the large capital investment that AMI rollouts typically entail. In particular, a central objective of the Smart Energy Pilot was to enable residential dynamic pricing (time-of-use “TOU” and critical peak rates and rebates) and two-way direct load control (“DLC”) by continually capturing AMR meter data transmissions and communicating through customer-sited broadband connections in conjunction with a standardsbased home area network (“HAN”). The pilot was supported by the U.S. Department of Energy’s (“DOE”) through the Smart Grid Demonstration program. NSTAR was very pleased to not only receive the funding support from DOE, but the guidance and support of the DOE throughout the pilot. NSTAR is also pleased to report to the DOE that it was able to execute and deliver a successful pilot on time and on budget. NSTAR looks for future opportunities to work with the DOE and others in future smart grid projects.

Playing Escape from DIAB (DIAB) and Nanoswarm (NANO) , epic video game adventures, increased fruit and vegetable consumption among a multi-ethnic sample of 10-12 year old children during pilot testing. Key elements of both games were educational mini-games embedded in the overall game that promoted knowledge acquisition regarding diet, physical activity and energy balance. 95-100% of participants demonstrated mastery of these mini-games suggesting knowledge acquisition. This article describes the process of designing and developing the educational mini-games. A secondary purpose was to explore the experience of children while playing the games. The educational games were based on Social Cognitive and Mastery Learning Theories. A multidisciplinary team of behavioral nutrition, PA, and video game experts designed, developed, and tested the mini-games. Alpha testing revealed children generally liked the mini-games and found them to be reasonably challenging. Process evaluation data from pilot testing revealed almost all participants completed nearly all educational mini-games in a reasonable amount of time suggesting feasibility of this approach. Future research should continue to explore the use of video games in educating children to achieve healthy behavior changes.

Cu cermet anodes were tested for 213 to 614 hours with an in-situ deposited CEROX coating in a pilot cell operated by Reynolds Manufacturing Technology Laboratory. At high bath ratio ({approximately}1.5) and low current density (0.5 A/cm{sup 2}), a {ge}1 mm thick dense CEROX coating was deposited on the anodes. At lower bath ratios and higher current density, the CEROX coating was thinner and less dense, but no change in corrosion rate was noted. Regions of low current density on the anodes and sides adjacent to the carbon anode sometimes had thin or absent CEROX coatings. Problems with cracking and oxidation of the cermet substrates led to higher corrosion rates in a pilot cell than would be anticipated from lab scale results.

Full Text Available Introduction: Obesity and overweight are among the main risk factors in the world today. In Spain, more than half of the children are above their ideal weight. The aim of this study was to show the pilot experience of the activities of food and nutrition education which were carried out in the State School “La Serranica “ in Aspe (Spain to promote the acquisition of knowledge and healthy eating habits and assess the impact of such intervention. Material and Methods: The study was developed in a population of 28 students of 3rd of Primary School in “La Serranica” in Aspe (Alicante, Spain. Results: The student response was positive. After the intervention, more than 70% of children placed the food correctly in the pyramid, identified season fruits and vegetables, and a healthy breakfast. However, the percentage decreased two years later, except for recognizing a healthy breakfast (89%. In relation to lunch, consumption of fruits increased in 18% at the end of the period of the activities, and consumption of pastries and commercial juices decreased. Anybody took for lunch pastries and most of them consumed sandwich and/or fruit two years after intervention. Conclusions: An educational intervention about food and nutrition produces positive changes on the population, significantly improving knowledge and consumption of healthy food and decreasing consumption of unhealthy foods. Therefore, it could be said that nutrition programmes education are needed in today’s society to prevent the problem of overweight and obesity and promote healthy habits.

This study was carried out to compare the effect between nutrition education intervention and non-nutrition education intervention on awareness regarding iron deficiency among schooling adolescents in Tanah Merah, one of rural district in Kelantan, Malaysia. This study which was started in year 2010 involved 280 respondents (223 girls, 57 boys, age: 16 yr) from schools in Tanah Merah. The selection criteria were based on hemoglobin level (Hb = 7 - 11.9 g/dL for girls; Hb = 7 - 12.9 g/dL for boys). They were divided into 2 groups. The first group received nutrition education package (Nutrition education, NE), whereas another group was entitled to receive non-nutrition education intervention (Non-Nutrition Education, NNE) (supplement only). Both interventions were implemented for 3 months. The changes in awareness among respondents of both groups were evaluated using multi-choices questionnaire. Nutrition education receiver group (NE) demonstrated improvement in awareness at post-intervention. No substantial improvement was demonstrated by the counterpart group (NNE). Multimedia nutrition education program conducted at school setting was in fact practical and effective in improving awareness on iron deficiency among anemic adolescents.

This pilot study tested the effects of an interactive nutrition education Web site on fruit, vegetable, and fat consumption in minority adolescents genetically at risk for Type 2 diabetes. A one-group nonexperimental pretest, posttest focus group design was used. Twenty-one sixth-grade to eighth-grade junior high adolescents who were minorities volunteered to participate. Participants received 5 hours of Web-based nutrition education over 3 weeks. A significant difference in fat consumption was supported from the computerized dietary assessment. No difference was found in fruit or vegetable consumption. Comparative data indicated a rise in body mass index (BMI) percentile from 88.03 (1999) to 88.40 (2002; boys) and 88.25 (1999) to 91.2 (2002; girls). Focus group responses supported the satisfaction of adolescents in the study with the use of the Web-based intervention for nutrition education. Healthy eating interventions using Web-based nutrition education should be further investigated with adolescents.

The effect of testosterone and a nutritional supplement on hospital admissions in under-nourished, older people

Full Text Available Abstract Background Weight loss and under-nutrition are relatively common in older people, and are associated with poor outcomes including increased rates of hospital admissions and death. In a pilot study of 49 undernourished older, community dwelling people we found that daily treatment for one year with a combination of testosterone tablets and a nutritional supplement produced a significant reduction in hospitalizations. We propose a larger, multicentre study to explore and hopefully confirm this exciting, potentially important finding (NHMRC project grant number 627178. Methods/Design One year randomized control trial where subjects are allocated to either oral testosterone undecanoate and high calorie oral nutritional supplement or placebo medication and low calorie oral nutritional supplementation. 200 older community-dwelling, undernourished people [Mini Nutritional Assessment score 2: 7.5% over 3 months]. Hospital admissions, quality-adjusted life years, functional status, nutritional health, muscle strength, body composition and other variables will be assessed. Discussion The pilot study showed that combined treatment with an oral testosterone and a supplement drink was well tolerated and safe, and reduced the number of people hospitalised and duration of hospital admissions in undernourished, community dwelling older people. This is an exciting finding, as it identifies a treatment which may be of substantial benefit to many older people in our community. We now propose to conduct a multi-centre study to test these findings in a substantially larger subject group, and to determine the cost effectiveness of this treatment.

To evaluate the efficacy of a nutrition education intervention for college female athletes to improve nutrition knowledge, build self-efficacy with respect to making healthful dietary choices, and improve dietary intake. A pretest-posttest control group design was implemented. A women's soccer team (n =15) and a women's swim team (n = 15) were randomly assigned to experimental and control groups, respectively. The intervention focused on nutrition knowledge, self-efficacy in making healthful dietary choices, and dietary practices to demonstrate treatment effect. Dependent variables were nutrition knowledge, self-efficacy, and dietary practices. Independent variables were group assignment. The Mann-Whitney U test was used to analyze the results between groups, and the Fisher exact probability test was used to detect differences between groups in the number of positive dietary changes. Treatment participants significantly improved nutrition knowledge, self-efficacy (P nutrition education intervention research among athletes and demonstrates the ability to increase not only nutrition knowledge, which is typically reported, but also self-efficacy and improvement in overall positive dietary changes during an 8-week intervention.

Highlights: • The continuous pyrolysis of waste tire has been demonstrated at pilot scale in an auger reactor. • More than 500 kg of waste tires were processed in 100 operational hours. • The yields and characteristics of the pyrolysis products remained constant. • Mass and energy balances for an industrial scale plant are provided. • The reaction enthalpy necessary to perform the waste tire pyrolysis was determined. -- Abstract: This work shows the technical feasibility for valorizing waste tires by pyrolysis using a pilot scale facility with a nominal capacity of 150 kW th . A continuous auger reactor was operated to perform thirteen independent experiments that conducted to the processing of more than 500 kg of shredded waste tires in 100 h of operation. The reaction temperature was 550 °C and the pressure was 1 bar in all the runs. Under these conditions, yields to solid, liquid and gas were 40.5 ± 0.3, 42.6 ± 0.1 and 16.9 ± 0.3 wt.% respectively. Ultimate and proximate analyses as well as heating value analysis were conducted for both the solid and liquid fraction. pH, water content, total acid number (TAN), viscosity and density were also assessed for the liquid and compared to the specifications of marine fuels (standard ISO 8217). Gas chromatography was used to calculate the composition of the gaseous fraction. It was observed that all these properties remained practically invariable along the experiments without any significant technical problem. In addition, the reaction enthalpy necessary to perform the waste tire pyrolysis process (907.1 ± 40.0 kJ/kg) was determined from the combustion and formation enthalpies of waste tire and conversion products. Finally, a mass balance closure was performed showing an excellent reliability of the data obtained from the experimental campaign

of large quantities of spatially and non-spatially referenced data. For data integration of agriculture data FOODIE introduced the open data model. The open data model supported the evidence of all treatments that were used in a certain place as well as (where appropriate) to store relevant information on the application of those treatments. The stored data should together answer the questions like "What amount of which treatment was used in a certain place?", "When it will be safe to apply another treatment?" or "Is the treatment registered and allowed in the European Union/Member State?" The FOODIE data model is based on INSPIRE specification for Agricultural and Aquaculture Facilities., The FOODIE data model is based on the Activity Complex model.. Within INSPIRE, "Activity Complex" denotes a generic name agreed across thematic domains trying to avoid specific thematic connotations such as "Plant", "Installation", "Facility", "Establishment" or "Holding". Such scope may be identified for this paper as the Nitrate Directive or Water Framework Directive A Collection of data was verified on within the FOODIE Czech pilot farm with 1'214 ha of arable land to obtain information about farm machinery management and agro-meteorological observation. Selected tractors and implements were equipped by telemetry units to record vehicle trajectory in the fields and a wireless sensor network was established to observe meteorological conditions within a two fields with cereals. For these such purposes, a novel data model was developed to manage both sensor data and farm records within one platform simultaneously with the client application, which allows end-users to make visualization and analysis of farm data. The Czech Pilot is addressed to improve management and logistic of farms and agriculture service companies, introducing new tools and crop management methods for reduction of environmental burden while maintaining production level.

Despite the increased use of health claims in food advertising, few studies have investigated how specific nutrition claims have differential effects depending on how they are presented. In this context, the current study tests the anchoring hypothesis. Anchoring refers to a common human tendency to evaluate information differently depending on the presence or absence of a numerical "anchor" or reference point. Two (pilot and main) experimental studies explore anchoring effects on audience response to food advertising both directly and moderated by cognitive, motivational, and message factors. The pilot study finds that food product ads employing nutrition claims with an anchor rather than without an anchor generate two results: First, participants perceive the product to have lower fat/lower calorie contents (anchoring hypothesis); second, they prefer the messages with an anchor over those without an anchor. The main study reports that when anchoring is successfully evoked, it produces favorable attitudes toward the ad, favorable attitudes toward the brand, and purchase intention-but only when moderated by health orientation, claim believability, and nutrition knowledge. Practical implications are provided with respect to regulatory guidelines and effective communication strategies for promoting low-fat and low-calorie products in food advertising.

The Summer Electronic Benefit Transfers for Children (SEBTC) demonstration piloted summer food assistance through electronic benefit transfers (EBTs), providing benefits either through the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) or the Supplemental Nutrition Assistance Program (SNAP) EBT. To inform food assistance policy and describe how demonstrations using WIC and SNAP models differed in benefit take-up and impacts on food security and children's food consumption. Sites chose to deliver SEBTC using the SNAP or WIC EBT system. Within each site, in 2012, households were randomly assigned to a benefit group or a no-benefit control group. Grantees (eight states and two Indian Tribal Organizations) selected school districts serving many low-income children. Schoolchildren were eligible in cases where they had been certified for free or reduced-price meals during the school year. Before the demonstration, households in the demonstration sample had lower incomes and lower food security, on average, than households with eligible children nationally. Grantees provided selected households with benefits worth $60 per child per summer month using SNAP or WIC EBT systems. SNAP-model benefits covered most foods. WIC-model benefits could only be used for a specific package of foods. Key outcomes were children's food security (assessed using the US Department of Agriculture food security scale) and food consumption (assessed using food frequency questions). Differences in mean outcomes between the benefit and control groups measured impact, after adjusting for household characteristics. In WIC sites, benefit-group households redeemed a lower percentage of SEBTC benefits than in SNAP sites. Nonetheless, the benefit groups in both sets of sites had similar large reductions in very low food security among children, relative to no-benefit controls. Children receiving benefits consumed more healthful foods, and these impacts were larger in WIC

In contrast to the spectacular advances in the first half of the twentieth century with micronutrient-related diseases, human nutrition science has failed to stem the more recent rise of obesity and associated cardiometabolic disease (OACD). This failure has triggered debate on the problems and limitations of the field and what change is needed to address these. We briefly review the two broad historical phases of human nutrition science and then provide an overview of the main problems that have been implicated in the poor progress of the field with solving OACD. We next introduce the field of nutritional ecology and show how its ecological-evolutionary foundations can enrich human nutrition science by providing the theory to help address its limitations. We end by introducing a modeling approach from nutritional ecology, termed nutritional geometry, and demonstrate how it can help to implement ecological and evolutionary theory in human nutrition to provide new direction and to better understand and manage OACD.

Childhood obesity continues to be a problem. Children in rural populations are more likely to be overweight or obese and a lack of resources in those areas may contribute to this problem. We aimed to assess the impact of a pilot pharmacy health-care professional out-of-school time vigorous physical activity and nutrition education program on fourth and fifth graders in a rural Texas community. We conducted a prospective 12-week cohort study from August to November 2012. Thirty-three children, aged 8-11 years, in Bailey County, Texas, were enrolled in the study. Body mass index, body mass index percentile, blood pressure, waist circumference, and a diet preferences and activities knowledge survey were obtained at 0, 4, 8, and 12 weeks. Study participants completed a twice weekly physical activity and nutrition education program with exercise over weeks 1-4 with no intervention during weeks 5-12. Thirty-one (94%) of the 33 children, predominately Hispanic girls, completed the program. Body mass index (-0.30 (95% confidence interval, -0.44 to -0.17); P = Positive survey results at 3 months indicated a decrease in fried/sweet foods; increase in exercise; decreases in video games and computer use; and a change in knowledge regarding the selection of the most healthy food group servings per day. In this pharmacy health-care directed pilot study, participants had a reduction of body mass index, body mass index percentile, systolic blood pressure, waist circumference, and improvement in certain survey results at the end of 12 weeks despite no further intervention after 4 weeks.

In response to US Department of Energy directives, Argonne National Laboratory (ANL) has developed a waste minimization plan aimed at reducing the amount of wastes at this national research and development laboratory. Activities at ANL are primarily research- oriented and as such affect the amount and type of source reduction that can be achieved at this facility. The objective of ANL's waste minimization program is to cost-effectively reduce all types of wastes, including hazardous, mixed, radioactive, and nonhazardous wastes. The ANL Waste Minimization Plan uses a waste minimization audit as a systematic procedure to determine opportunities to reduce or eliminate waste. To facilitate these audits, a computerized bar-coding procedure is being implemented at ANL to track hazardous wastes from where they are generated to their ultimate disposal. This paper describes the development of the ANL Waste Minimization Plan and a pilot demonstration of the how the ANL Plan audited the hazardous waste generated within a selected divisions of ANL. It includes quantitative data on the generation and disposal of hazardous waste at ANL and describes potential ways to minimize hazardous wastes. 2 refs., 5 figs., 8 tabs

2012-01-01

Individualized nutritional support is important to pediatric cancer patients and should be integrated to the overall treatment of these patients. Analyze the nutritional status of cancer patients submitted to enteral nutrition (EN) and assess the adequacy of this form of nutrition. A case series study was carried out at the Pediatric Oncology Unit of the Institute of Integrative Medicine Professor Fernando Figueira (IMIP, Brazil, Recife-PE) between January and December 2009. Clinical and anthropometric data were obtained from medical charts and nutritional follow-up charts. Z scores for height for age, weight for age and body mass index for age indicators (H/A, W/A and BMI/A, respectively) were calculated using the AnthroPlus program. Caloric and protein requirements were calculated based on the recommendations of the Brazilian National Council of Oncologic Nutrition. At the beginning of EN, 32.4% of the sample had short stature and 23.9% were underweight based on the BMI/A indicator. The assessment of EN adequacy demonstrated that 49.3% reached the caloric requirements and 76.1% reached the protein requirements, with maximal intakes of 65.6 Kcal/Kg/day and 1.95 g of protein/kg/day. Malnourished patients had greater mean Z scores for W/A and BMI/A at the end of EN, whereas no significant changes were found among patients with adequate nutritional status and significant reductions in these indicators were found among those with overweight or obesity. The patients either maintained or achieved a significant improvement in nutritional status, which demonstrates the importance of nutritional support and follow up during hospitalization.

Within the field of nutrition education, social marketing has become a promising framework to systematically approach problems related to nutrition behavior. In 1997, the Colorado Nutrition Network began developing a social marketing campaign to promote healthful food choices among low-income Coloradans. A multifaceted formative evaluation plan that included focus groups, campaign concept pretesting, and a food frequency questionnaire was used to segment and scrutinize the target audience. The resulting pilot program was a blend of educational and marketing strategies targeting preschoolers that was implemented in Head Start classrooms. The 12-week intervention contained a narrow, behavior-based "try new foods" message, multiple nutrition education activities, and repeated opportunities to taste 13 novel foods. Key strategies used and findings from the formative evaluation process are presented herein in an effort to provide insight for nutrition educators interested in developing similar interventions.

Membrane bioreactor (MBR) is becoming popular for advanced wastewater treatment and water reuse. Air scouring to "shake" the membrane fibers is most suitable and applicable to maintain filtration without severe and rapidfouling. However, membrane fouling mitigating technologies are energy intensive. The goal of this research is to develop an alternative energy-saving MBR system to reduce energy consumption; a revolutionary system that will directly compete with air scouring technologies currently in the membrane water reuse market. The innovative MBR system, called reciprocation MBR (rMBR), prevents membrane fouling without the use of air scouring blowers. The mechanism featured is a mechanical reciprocating membrane frame that uses inertia to prevent fouling. Direct strong agitation of the fiber is also beneficial for the constant removal of solids built up on the membrane surface. The rMBR pilot consumes less energy than conventional coarse air scouring MBR systems. Specific energy consumption for membrane reciprocation for the pilot rMBR system was 0.072 kWh/m3 permeate produced at 40 LMH, which is 75% less than the conventional air scouring in an MBR system (0.29 kWh/m3). Reciprocation of the hollow-fiber membrane can overcome the hydrodynamic limitations of air scouring or cross-flow membrane systems with less energy consumption and/or higher energy efficiency.

Nutrition has long been associated with skin health, including all of its possible aspects from beauty to its integrity and even the aging process. Multiple pathways within skin biology are associated with the onset and clinical course of various common skin diseases, such as acne, atopic dermatitis, aging, or even photoprotection. These conditions have been shown to be critically affected by nutritional patterns and dietary interventions where well-documented studies have demonstrated beneficial effects of essential nutrients on impaired skin structural and functional integrity and have restored skin appearance and health. Although the subject could be vast, the intention of this review is to provide the most relevant and the most well-documented information on the role of nutrition in common skin conditions and its impact on skin biology.

The primary objective of the biological treatment project is to develop and demonstrate a process for Hanford groundwater remediation. Biodenitrification using facultative anaerobic microorganisms is a promising technology for the simultaneous removal of nitrates and organics from contaminated aqueous streams. During FY 1988, a consortium of Hanford groundwater microorganisms was shown to degrade both nitrates and carbon tetrachloride (CC1 4 ). A pilot-scale treatment system was designed and constructed based on the results of laboratory-and-bench-scale testing. This report summarizes the results of biological groundwater treatment studies performed during FY 1989 at the pilot-scale. These tests were conducted using a simulated Hanford groundwater with a continuous stirred-tank bioreactor, and a fluidized-bed bioreactor that was added to the pilot-scale treatment system in FY 1989. The pilot-scale system demonstrated continuous degradation of nitrates and CC1 4 in a simulated groundwater. 4 refs., 7 figs., 1 tab

Malnutrition is a serious concern for children with cancer and nutrition screening may offer a simple alternative to nutrition assessment for identifying children with cancer who are at risk of malnutrition. The present paper aimed to evaluate the nutrition screening tool for childhood cancer (SCAN). SCAN was developed after an extensive review of currently available tools and published screening recommendation, consideration of pediatric oncology nutrition guidelines, piloting questions, and consulting with members of International Pediatric Oncology Nutrition Group. In Study 1, the accuracy and validity of SCAN against pediatric subjective global nutrition assessment (pediatric SGNA) was determined. In Study 2, subjects were classified as 'at risk of malnutrition' and 'not at risk of malnutrition' according to SCAN and measures of height, weight, body mass index (BMI) and body composition were compared between the groups. The validation of SCAN against pediatric SGNA showed SCAN had 'excellent' accuracy (0.90, 95% CI 0.78-1.00; p malnutrition' and 'not at risk of malnutrition' according to SCAN, the 'at risk of malnutrition' group had significantly lower values for weight Z score (p = 0.001), BMI Z score (p = 0.001) and fat mass index (FMI) (p = 0.04), than the 'not at risk of malnutrition' group. This study shows that SCAN is a simple, quick and valid tool which can be used to identify children with cancer who are at risk of malnutrition.

[MODen: Psychoeducationnal therapeutic group program for schizophrenic patients, based on nutritional balance and pleasure, using cognitive functions: A pilot study].

Science.gov (United States)

Farhat, S L; Hochard, C; Orens, S; Gautier, C; Lambert, T; Geret, L; Bralet, M C

2016-10-01

Schizophrenia causes psychological difficulties (with positive and/or negative symptoms) as well as cognitive disabilities (attention, memory, executive functions and social cognition). Moreover, 40 to 60% of patients suffer from an excess of weight or obesity (due to bad eating habits, eating disorders or medication). All these difficulties impair their autonomy and their insertion into the society. In this context, setting-up a therapeutic tool, which may have cognitive benefits seems relevant. Thus, MODen is a therapeutic educational tool whose aim is to improve cognitive functions and the symptoms by using "nutritional balance" as an aid. In this treatment program, two therapists lead a group of 5 to 8 patients which group meets once a week during two to four hours for 16 weeks, divided in 4 cycles. The first three weeks of each cycle consists of theoretical instruction: patients talk about their eating habits, information is given about nutritional balance and preparation of meals. In the different cycles, flexibility, planning, memory and attention are trained. For instance, the work on categorisation of foods and nutritional balance allow enhancing flexibility abilities. Writing down the lists of different ingredients needed for one week's meals and preparation of meals train planning abilities. MODen also takes into account ecological issues such as the limited budget of patients to do their shopping (this budget is around 4 euros per meal in France). The budget is also linked to planning abilities and reasoning. Finally, during the last session of each cycle the group prepares a meal (from the shopping to cooking). This last session is all about sharing and social cognition abilities. By the end of the program, patients will have prepared four meals together. Also "homework" has to be done each week in order to facilitate memorisation of what has been learned during the last session and to prepare the beginning of the next session. In a pilot study with 8

Pilot-scale treatability testing -- Recycle, reuse, and disposal of materials from decontamination and decommissioning activities: Soda blasting demonstration

International Nuclear Information System (INIS)

1995-08-01

The US Department of Energy (DOE) is in the process of defining the nature and magnitude of decontamination and decommissioning (D and D) obligations at its sites. With disposal costs rising and available storage facilities decreasing, DOE is exploring and implementing new waste minimizing D and D techniques. Technology demonstrations are being conducted by LMES at a DOE gaseous diffusion processing plant, the K-25 Site, in Oak Ridge, Tennessee. The gaseous diffusion process employed at Oak Ridge separated uranium-235 from uranium ore for use in atomic weapons and commercial reactors. These activities contaminated concrete and other surfaces within the plant with uranium, technetium, and other constituents. The objective of current K-25 D and D research is to make available cost-effective and energy-efficient techniques to advance remediation and waste management methods at the K-25 Site and other DOE sites. To support this objective, O'Brien and Gere tested a decontamination system on K-25 Site concrete and steel surfaces contaminated with radioactive and hazardous waste. A scouring system has been developed that removes fixed hazardous and radioactive surface contamination and minimizes residual waste. This system utilizes an abrasive sodium bicarbonate medium that is projected at contaminated surfaces. It mechanically removes surface contamination while leaving the surface intact. Blasting residuals are captured and dissolved in water and treated using physical/chemical processes. Pilot-scale testing of this soda blasting system and bench and pilot-scale treatment of the generated residuals were conducted from December 1993 to September 1994

Food Choices and Consequences for the Nutritional Status: Insights into Nutrition Transition in an Hospital Community.

Directory of Open Access Journals (Sweden)

Jitendra Piple

Full Text Available Although economic development is generally accompanied by improvements in the overall nutritional status of the country's population the 'nutritional transition' often involves a shift to high energy diets and less exercise with negative consequences. This pilot study was done to examine if education of parents operates at the household level to influence dietary choices and the nutritional status of children in a small community of hospital workers.3 groups of persons with varying skill and education levels participated. Weighed food logs were used in all households to calculate 'adult equivalent' per-capita-consumption. Nutrients were calculated using nutrients calculator software. BMI was used to classify children as underweight, normal weight and overweight.128 individuals participated from 30 families included 47 children. 10 children (21% were underweight, 29 (62% were normal and 8 (17% were overweight. Energy consumption was highest in families with overweight children 2692 +/-502 compared to 2259 +/-359 in families with normal weight and 2031+/-354 in the family of underweight children. These differences were statistically significant. 42% underweight children belonged to Class 1 at the lowest skill level and there were no overweight children in this group. Most of the overweight children belonged to Class 2. In Class 3 there were no underweight children and the majority was normal weight children.Underweight children came from the poorer households. Per capita intake of the family as a whole correlated well with BMI in the children. There was increased obesity in middle income families belonging to Class 2-probably in families who move up the scale from deprivation. Nutritional status in children correlated mostly with maternal education status.

2010-01-01

Given the foundational importance of literature searching skills to later stages of research and, ultimately, evidence-based practice, the authors wanted to assess a unique strategy for teaching such skills. This pilot study describes the results of an undergraduate nutrition research course in which a librarian lead several class sessions. The goal of this study was to assess students' perceptions, attitudes and use of research literature and resources before and after a course partially taught by a librarian. Twenty-seven students enrolled in an undergraduate Introduction to Research course at Georgia State University were given pre- and post-test questionnaires at the beginning and end of a course that included three librarian-led class sessions. Most of the results indicate that the repeated involvement of a librarian enriched this particular undergraduate research course. By the end of the course, students were more comfortable in libraries and with using library resources; they used the campus library more frequently; they were more confident in their ability to find high-quality information on nutrition-related topics and identify strengths and weaknesses of different information sources; and they felt they gained skills that will help them achieve their educational and career goals.

Nutrition therapy issues in esophageal cancer.

Science.gov (United States)

Miller, Keith R; Bozeman, Matthew C

2012-08-01

Esophageal cancer has traditionally been a disease with poor long term outcomes in terms of both survival and quality of life. In combination with surgical and pharmacologic therapy, nutrition support has been demonstrated to improve patient tolerance of treatment, quality of life, and longterm outcomes. An aggressive multi-disciplinary approach is warranted with nutrition support remaining a cornerstone in management. Historically, nutrition support has focused on adequate caloric provision to prevent weight loss and allow for tolerance of treatment regimens. Alterations in metabolism occur in these patients making their use of available calories inefficient and the future of nutritional support may lie in the ability to alter this deranged metabolism. The purpose of this article is to review the current literature surrounding the etiology, treatment, and role of nutrition support in improving outcomes in esophageal cancer.

Intake of saturated fat, trans fat, and cholesterol has been associated with increased risk of coronary heart disease. The aim of this study was to explore whether increased nutrition knowledge is associated with a reduction in the consumption of unhealthy fats in a sample of university students. A sample of 231 students, with a mean age of 20 years, was recruited from university campus during spring 2012. Students completed a validated questionnaire related to students' demographic, nutrition knowledge, and daily fat consumption. Weight, height, and waist circumference were measured. Data were analyzed using one-way ANOVA, chi-square, and student's t-test. Results indicate that female students have greater nutrition knowledge than male students (the mean nutrition score for women was 5 points higher than that of men (P = 0.01)). Nutrition knowledge was negatively correlated with fat and cholesterol intake. Students who consumed more than 35 % calories from fat or >300 mg of cholesterol daily had lower mean nutrition scores than those students with lower fat or cholesterol intake (8 points lower and 7.9 points lower, respectively). Using linear regression for nutrition scores on estimated saturated fat intake and cholesterol intake (controlling for gender, height, weight, age, and dieting), nutrition scores were negatively associated with saturated fat intake (-0.15, P Students with greater nutritional knowledge consumed less unhealthy fats and cholesterol. This finding magnifies the role of nutrition education as a potential tool in health campaigns to promote healthy eating patterns among college students. Results of this pilot study can inform the design of future nutrition education intervention studies to assess the efficacy of nutrition knowledge on pattern of fat consumption among college students.

Assessing nutritional diversity of cropping systems in African villages.

Directory of Open Access Journals (Sweden)

Roseline Remans

Full Text Available BACKGROUND: In Sub-Saharan Africa, 40% of children under five years in age are chronically undernourished. As new investments and attention galvanize action on African agriculture to reduce hunger, there is an urgent need for metrics that monitor agricultural progress beyond calories produced per capita and address nutritional diversity essential for human health. In this study we demonstrate how an ecological tool, functional diversity (FD, has potential to address this need and provide new insights on nutritional diversity of cropping systems in rural Africa. METHODS AND FINDINGS: Data on edible plant species diversity, food security and diet diversity were collected for 170 farms in three rural settings in Sub-Saharan Africa. Nutritional FD metrics were calculated based on farm species composition and species nutritional composition. Iron and vitamin A deficiency were determined from blood samples of 90 adult women. Nutritional FD metrics summarized the diversity of nutrients provided by the farm and showed variability between farms and villages. Regression of nutritional FD against species richness and expected FD enabled identification of key species that add nutrient diversity to the system and assessed the degree of redundancy for nutrient traits. Nutritional FD analysis demonstrated that depending on the original composition of species on farm or village, adding or removing individual species can have radically different outcomes for nutritional diversity. While correlations between nutritional FD, food and nutrition indicators were not significant at household level, associations between these variables were observed at village level. CONCLUSION: This study provides novel metrics to address nutritional diversity in farming systems and examples of how these metrics can help guide agricultural interventions towards adequate nutrient diversity. New hypotheses on the link between agro-diversity, food security and human nutrition are

To investigate the effects of early enteral nutrition (EEN) on intra-abdominal pressure (IAP) and disease severity in patients with severe acute pancreatitis (SAP). Enteral nutrition (EN) was started within 48 h after admission in the EEN group and from the 8th day in the delayed enteral nutrition (DEN) group. The IAP and intra-abdominal hypertension (IAH) incidence were recorded for 2 weeks. The caloric intake and feeding intolerance (FI) incidence were recorded daily after EN was started. The severity markers and clinical outcome variables were also recorded. Sixty patients were enrolled to this study. No difference about IAP was found. The IAH incidence of the EEN group was significantly lower than that of the DEN group from the 9th day (8/30 versus 18/30; P = 0.009) after admission. The FI incidence of the EEN group was higher than that of the DEN group during the initial 3 days of feeding (25/30 versus 12/30; P = 0.001; 22/30 versus 9/30; P = 0.001; 15/30 versus 4/30; P = 0.002). Patients with an IAP FI incidence than those with an IAP ≥15 mmHg on the 1st day (20/22 versus 17/38; P < 0.001), the 3rd day (11/13 versus 8/47; P < 0.001), and the 7th day (3/5 versus 3/55; P = 0.005) of feeding. The severity markers and clinical outcome variables of the EEN group were significantly improved. Early enteral nutrition did not increase IAP. In contrast, it might prevent the development of IAH. In addition, EEN might be not appropriate during the initial 3-4 days of SAP onset. Moreover, EN might be of benefit to patients with an IAP <15 mmHg. Early enteral nutrition could improve disease severity and clinical outcome, but did not decrease mortality of SAP.

We have prepared a review of the physical-chemical composition and the functional and anti-nutritional properties of quinoa (Chenopodium quinoa Willd.). It is a plant of the Chenopodiaceae family, originally from the Andean regions, adaptable to different types of soils and climatic conditions. Its composition has attracted the attention of scientific community for its high nutritional value, being rich in proteins, lipids, fibers, vitamins, and minerals, with an extraordinary balance of essential amino acids. It is also gluten-free, a characteristic that enables its use by celiac patients. In spite of all these attributes, quinoa is not widely used by consumers due to the high cost of imported grain and little knowledge of its benefits. More studies are required to increase knowledge about this "pseudo-cereal" to demonstrate its functional and nutritional benefits and to study its anti-nutritional effects, since it presents high commercial value and excellent nutritional quality.

To demonstrate the feasibility of introducing a main dish designed by a professional chef in the National School Lunch Program and to document the impact on child participation, a chef was recruited to design pizza to be served in an upstate New York school district. The pizza was designed to meet both the cost and ingredient requirements of the NSLP. High school students were significantly more likely to select the pizza prepared by the chef. While the chef had no significant impact on main dish consumption given selection, more students took a vegetable and vegetable consumption increased by 16.5%. This pilot study demonstrates the plausibility of using chefs to boost participation in the school lunch program, and potentially increase nutrition through side selection, among high school students.

Nutritional supplementation for Alzheimer's disease?

Science.gov (United States)

Shea, Thomas B; Remington, Ruth

2015-03-01

Evidence for the benefit of nutrition in Alzheimer's disease continues to accumulate. Many studies with individual vitamins or supplements show marginal, if any, benefit. However, new findings with combinatorial formulations demonstrate improvement in cognitive performance and behavioral difficulties that accompany Alzheimer's disease. Herein, we review some of the most recent clinical advances and summarize supportive preclinical studies. We present novel positive effects on Alzheimer's disease derived from diet, trace elements, vitamins and supplements. We discuss the inherent difficulty in conducting nutritional studies because of the variance in participants' nutritional history, versus pharmacological interventions in which participants are naive to the intervention. We examine the evidence that epigenetics play a role in Alzheimer's disease and how nutritional intervention can modify the key epigenetic events to maintain or improve cognitive performance. Overall consideration of the most recent collective evidence suggests that the optimal approach for Alzheimer's disease would seem to combine early, multicomponent nutritional approaches (a Mediterranean-style diet, multivitamins and key combinatorial supplements), along with lifestyle modifications such as social activity and mental and physical exercise, with ultimate addition of pharmacological agents when warranted.

Piloting and dead reckoning navigation strategies use very different cue constellations and computational processes (Darwin, 1873; Barlow, 1964; O'Keefe and Nadel, 1978; Mittelstaedt and Mittelstaedt, 1980; Landeau et al., 1984; Etienne, 1987; Gallistel, 1990; Maurer and Se guinot, 1995). Piloting requires the use of the relationships between relatively stable external (visual, olfactory, auditory) cues, whereas dead reckoning requires the integration of cues generated by self-movement. Animals obtain self-movement information from vestibular receptors, and possibly muscle and joint receptors, and efference copy of commands that generate movement. An animal may also use the flows of visual, auditory, and olfactory stimuli caused by its movements. Using a piloting strategy an animal can use geometrical calculations to determine directions and distances to places in its environment, whereas using an dead reckoning strategy it can integrate cues generated by its previous movements to return to a just left location. Dead reckoning is colloquially called "sense of direction" and "sense of distance." Although there is considerable evidence that the hippocampus is involved in piloting (O'Keefe and Nadel, 1978; O'Keefe and Speakman, 1987), there is also evidence from behavioral (Whishaw et al., 1997; Whishaw and Maaswinkel, 1998; Maaswinkel and Whishaw, 1999), modeling (Samsonovich and McNaughton, 1997), and electrophysiological (O'Mare et al., 1994; Sharp et al., 1995; Taube and Burton, 1995; Blair and Sharp, 1996; McNaughton et al., 1996; Wiener, 1996; Golob and Taube, 1997) studies that the hippocampal formation is involved in dead reckoning. The relative contribution of the hippocampus to the two forms of navigation is still uncertain, however. Ordinarily, it is difficult to be certain that an animal is using a piloting versus a dead reckoning strategy because animals are very flexible in their use of strategies and cues (Etienne et al., 1996; Dudchenko et al., 1997

A process has been developed that exploits the characteristics of microwave heating for the vitrification of high-level radioactive liquid waste. This process, microwave vitrification, has been successfully operated at pilot plant scale in an active cell using simulated liquid waste containing several curies of radioactivity. Excellent decontamination factors have been achieved for both volatiles and nonvolatiles with an average ruthenium decontamination factor of 490 and a gross alpha emitter decontamination factor of 100,000. Almost all the radioactivity is incorporated in a glass block

2016-01-01

Animals have evolved complex foraging strategies to obtain a nutritionally balanced diet and associated fitness benefits. Recent research combining state-space models of nutritional geometry with agent-based models (ABMs), show how nutrient targeted foraging behavior can also influence animal social interactions, ultimately affecting collective dynamics and group structures. Here we demonstrate how social network analyses can be integrated into such a modeling framework and provide a practical analytical tool to compare experimental results with theory. We illustrate our approach by examining the case of nutritionally mediated dominance hierarchies. First we show how nutritionally explicit ABMs that simulate the emergence of dominance hierarchies can be used to generate social networks. Importantly the structural properties of our simulated networks bear similarities to dominance networks of real animals (where conflicts are not always directly related to nutrition). Finally, we demonstrate how metrics from social network analyses can be used to predict the fitness of agents in these simulated competitive environments. Our results highlight the potential importance of nutritional mechanisms in shaping dominance interactions in a wide range of social and ecological contexts. Nutrition likely influences social interactions in many species, and yet a theoretical framework for exploring these effects is currently lacking. Combining social network analyses with computational models from nutritional ecology may bridge this divide, representing a pragmatic approach for generating theoretical predictions for nutritional experiments.

To improve the nutritional status of homeless children by implementing an educational program for their mothers and the cafeteria staff at a homeless shelter. Program evaluation including before and after measures of mothers' nutritional knowledge and nutritional quality of foods served in the cafeteria. Fifty-six mothers with children aged 18 months to 6 years and 3 cafeteria staff. Four nutrition classes developed by a registered nutritionist were taught to mothers by clinic nurses; 3 nutrition classes were taught to the cafeteria staff by the nutritionist. Mothers scored higher on posttests than on pretests, indicating improved nutritional knowledge. Minimal differences in the nutritional quality of foods served to residents were observed after staff education. This project demonstrates the challenges of altering the nutritional status of children in a homeless shelter. Despite mothers showing better knowledge of nutritional requirements for children, the types of food served in the cafeteria were an obstacle to them in practicing what they had learned. The cafeteria staff's ability to demonstrate their learning was impeded by the constraints of food donations. Educational strategies may need to be augmented by policies to improve the nutritional status of children in homeless shelters.

Nutritional Supplements for Endurance Athletes

Science.gov (United States)

Rasmussen, Christopher J.

Athletes engaged in heavy endurance training often seek additional nutritional strategies to help maximize performance. Specific nutritional supplements exist to combat certain factors that limit performance beginning with a sound everyday diet. Research has further demonstrated that safe, effective, legal supplements are in fact available for today's endurance athletes. Several of these supplements are marketed not only to aid performance but also to combat the immunosuppressive effects of intense endurance training. It is imperative for each athlete to research the legality of certain supplements for their specific sport or event. Once the legality has been established, it is often up to each individual athlete to decipher the ethics involved with ingesting nutritional supplements with the sole intent of improving performance.

DESIGN OF SMALL AUTOMATION WORK CELL SYSTEM DEMONSTRATIONS

International Nuclear Information System (INIS)

TURNER, C.; PEHL, J.

2000-01-01

The introduction of automation systems into many of the facilities dealing with the production, use and disposition of nuclear materials has been an ongoing objective. Many previous attempts have been made, using a variety of monolithic and, in some cases, modular technologies. Many of these attempts were less than successful, owing to the difficulty of the problem, the lack of maturity of the technology, and over optimism about the capabilities of a particular system. Consequently, it is not surprising that suggestions that automation can reduce worker Occupational Radiation Exposure (ORE) levels are often met with skepticism and caution. The development of effective demonstrations of these technologies is of vital importance if automation is to become an acceptable option for nuclear material processing environments. The University of Texas Robotics Research Group (UTRRG) has been pursuing the development of technologies to support modular small automation systems (each of less than 5 degrees-of-freedom) and the design of those systems for more than two decades. Properly designed and implemented, these technologies have a potential to reduce the worker ORE associated with work in nuclear materials processing facilities. Successful development of systems for these applications requires the development of technologies that meet the requirements of the applications. These application requirements form a general set of rules that applicable technologies and approaches need to adhere to, but in and of themselves are generally insufficient for the design of a specific automation system. For the design of an appropriate system, the associated task specifications and relationships need to be defined. These task specifications also provide a means by which appropriate technology demonstrations can be defined. Based on the requirements and specifications of the operations of the Advanced Recovery and Integrated Extraction System (ARIES) pilot line at Los Alamos National

The Vendée Globe is a solo round-the-world sailing race without stopovers or assistance, a physically demanding challenge for which appropriate nutrition should maintain energy balance and ensure optimum performance. This is an account of prerace nutritional preparation with a professional and experienced female racer and assessment of daily nutritional intake (NI) during the race using a multimethod approach. A daily energy intake (EI) of 15.1 MJ/day was recommended for the race and negotiated down by the racer to 12.7 MJ/day, with carbohydrate and fluid intake goals of 480 g/day and 3,020 ml/day, respectively. Throughout the 99-day voyage, daily NI was recorded using electronic food diaries and inventories piloted during training races. NI was assessed and a postrace interview and questionnaire were used to evaluate the intervention. Fat mass (FM) and fat-free mass (FFM) were assessed pre- (37 days) and postrace (11 days) using dual-energy X-ray absorptiometry, and body mass was measured before the racer stepped on the yacht and immediately postrace. Mean EI was 9.2 MJ/day (2.4-14.3 MJ/day), representing a negative energy balance of 3.5 MJ/day under the negotiated EI goal, evidenced by a 7.9-kg loss of body mass (FM -7.5 kg, FFM -0.4 kg) during the voyage, with consequent underconsumption of carbohydrate by ~130 g/day. According to the postrace yacht food inventory, self-reported EI was underreported by 7%. This intervention demonstrates the practicality of the NI approach and assessment, but the racer's nutrition strategy can be further improved to facilitate meeting more optimal NI goals for performance and health. It also shows that evaluation of NI is possible in this environment over prolonged periods, which can provide important information for optimizing nutritional strategies for ocean racing.

The fuel spray distribution in a DI diesel engine with a pilot injection was actively controlled by pilot and main fuel injections at different piston positions to avoid the main fuel injection from hitting the pilot flame. A CFD analysis demonstrated that the movement of the piston with a cavity divided by a central lip along the center of the sidewall effectively separated the cores of the pilot and main fuel sprays. The experiments showed that more smoke was emitted with pilot injection in an ordinary cavity without the central lip while smokeless and low NO{sub x} operation was realized with pilot injection in a cavity divided by a central lip even at heavy loads where ordinary operation without pilot injection emitted smoke so much. The indicated specific energy consumption ISEC was a little bit higher with the pilot injection, mainly because of the reduction in the degree of constant volume combustion. With the advanced pilot injection, ISEC was improved more than that with the retarded pilot injection while the NO{sub x} is a little higher than the retarded pilot injection maintaining still much lower than in ordinary operation.

Parenteral nutrition (PN) provision is complex, as it is a high-alert medication and prone to a variety of potential errors. With changes in clinical practice models and recent federal rulings, the number of PN prescribers may be increasing. Safe prescribing of this therapy requires that competency for prescribers from all disciplines be demonstrated using a standardized process. A standardized model for PN prescribing competency is proposed based on a competency framework, the American Society for Parenteral and Enteral Nutrition (A.S.P.E.N.)-published interdisciplinary core competencies, safe practice recommendations, and clinical guidelines. This framework will guide institutions and agencies in developing and maintaining competency for safe PN prescription by their staff. © 2015 American Society for Parenteral and Enteral Nutrition.

Malnutrition, cachexia and nutritional intervention: when much becomes too much

Serena Rianda

Full Text Available Disease-associated malnutrition, also defined as cachexia, is a complex syndrome characterised by the progressive deterioration of nutritional status resulting from the combined effects of reduced appetite and food intake, and profound changes in host metabolism. Cachexia has been repeatedly demonstrated to represent a negative prognostic factor for patients suffering from acute and chronic diseases, including cancer. In oncology patients, early diagnosis of cachexia and timely nutritional intervention have been demonstrated not only to prevent further deterioration of nutritional status, but also to increase quality of life and survival when integrated in a multiprofessional and multidisciplinary approach. However, nutritional therapy is associated to the possible development of complications, which may be fatal. Therefore, nutritional therapy in severely malnourished patients should be cautiously prescribed by experts in the field, who should develop a monitoring program to early detect complications and to maximise the clinical efficacy.Here we describe a cancer patient affected by refeeding syndrome, who was fortunately early diagnosed and properly treated.

Patients with end-stage cancer and advanced chronic bowel disease are often malnourished, which has a negative effect on patients' outcome, well-being, and activity. It is inconclusive whether these patients benefit from home parenteral nutrition. This prospective exploratory study investigates its influence on nutrition state, muscle strength, mobility, and quality of life. Patients ≥18 years old with an indication for home parenteral nutrition were included and followed for 2-24 months. Nutrition parameters, activity, and quality of life were assessed. Forty-eight patients participated (mean age 11.5 years), and 85% were severely malnourished (subjective global assessment score, class C). Four weeks after parenteral nutrition, patients with tumors demonstrated a deterioration in phase angle (from 3.9 to 3.4) and extracellular mass:body cell mass ratio (from 1.6 to 2.1), while patients with bowel disease improved (from 3.4 to 4.0 and 2.1 to 1.6, respectively); grip strength remained constant in both groups (difference: 1.11 and -2.11, respectively). Activity improved in patients with bowel disease but stayed the same in the tumor group (P = .02 and P = .33, respectively). When the groups were pooled, emotional and social functioning domain scores (P parenteral nutrition. Both groups seem to benefit from home parenteral nutrition without harmful side effects. If the indication is determined early, the patients' disease course could perhaps be improved. © 2016 American Society for Parenteral and Enteral Nutrition.

Slipstream pilot-scale demonstration of a novel amine-based post-combustion technology for carbon dioxide capture from coal-fired power plant flue gas

Post-combustion CO₂ capture (PCC) technology offers flexibility to treat the flue gas from both existing and new coal-fired power plants and can be applied to treat all or a portion of the flue gas. Solvent-based technologies are today the leading option for PCC from commercial coal-fired power plants as they have been applied in large-scale in other applications. Linde and BASF have been working together to develop and further improve a PCC process incorporating BASF’s novel aqueous amine-based solvent technology. This technology offers significant benefits compared to other solvent-based processes as it aims to reduce the regeneration energy requirements using novel solvents that are very stable under the coal-fired power plant feed gas conditions. BASF has developed the desired solvent based on the evaluation of a large number of candidates. In addition, long-term small pilot-scale testing of the BASF solvent has been performed on a lignite-fired flue gas. In coordination with BASF, Linde has evaluated a number of options for capital cost reduction in large engineered systems for solvent-based PCC technology. This report provides a summary of the work performed and results from a project supported by the US DOE (DE-FE0007453) for the pilot-scale demonstration of a Linde-BASF PCC technology using coal-fired power plant flue gas at a 1-1.5 MWe scale in Wilsonville, AL at the National Carbon Capture Center (NCCC). Following a project kick-off meeting in November 2011 and the conclusion of pilot plant design and engineering in February 2013, mechanical completion of the pilot plant was achieved in July 2014, and final commissioning activities were completed to enable start-up of operations in January 2015. Parametric tests were performed from January to December 2015 to determine optimal test conditions and evaluate process performance over a variety of operation parameters. A long-duration 1500-hour continuous test campaign was performed from May to

2016-06-01

Full Text Available Nutritional cognitive neuroscience is an emerging interdisciplinary field of research that seeks to understand nutrition’s impact on cognition and brain health across the life span. Research in this burgeoning field demonstrates that many aspects of nutrition – from entire diets to specific nutrients – affect brain structure and function, and therefore have profound implications for understanding the nature of healthy brain aging. The aim of this Focused Review is to examine recent advances in nutritional cognitive neuroscience, with an emphasis on methods that enable discovery of nutrient biomarkers that predict healthy brain aging. We propose an integrative framework that calls for the synthesis of research in nutritional epidemiology and cognitive neuroscience, incorporating: (i methods for the precise characterization of nutritional health based on the analysis of nutrient biomarker patterns, along with (ii modern indices of brain health derived from high-resolution magnetic resonance imaging. By integrating cutting-edge techniques from nutritional epidemiology and cognitive neuroscience, nutritional cognitive neuroscience will continue to advance our understanding of the beneficial effects of nutrition on the aging brain and establish effective nutritional interventions to promote healthy brain aging.

A considerable percentage of flight crew reports to be fatigued regularly. This is partly caused by irregular and long working hours and the crossing of time zones. It has been shown that persistent fatigue can lead to health problems, impaired performance during work, and a decreased work-private life balance. It is hypothesized that an intervention consisting of tailored advice regarding exposure to daylight, optimising sleep, physical activity, and nutrition will lead to a reduction of fatigue in airline pilots compared to a control group, which receives a minimal intervention with standard available information. The study population will consist of pilots of a large airline company. All pilots who posses a smartphone or tablet, and who are not on sick leave for more than four weeks at the moment of recruitment, will be eligible for participation.In a two-armed randomised controlled trial, participants will be allocated to an intervention group that will receive the tailored advice to optimise exposure to daylight, sleep, physical activity and nutrition, and a control group that will receive standard available information. The intervention will be applied using a smartphone application and a website, and will be tailored on flight- and participant-specific characteristics. The primary outcome of the study is perceived fatigue. Secondary outcomes are need for recovery, duration and quality of sleep, dietary and physical activity behaviours, work-private life balance, general health, and sickness absence. A process evaluation will be conducted as well. Outcomes will be measured at baseline and at three and six months after baseline. This paper describes the development of an intervention for airline pilots, consisting of tailored advice (on exposure to daylight and sleep-, physical activity, and nutrition) applied into a smartphone application. Further, the paper describes the design of the randomised controlled trial evaluating the effect of the intervention on

Nutrition is important for preventing and treating chronic diseases highly prevalent among Latinos, yet no tool exists for measuring nutrition literacy among Spanish speakers. This study aimed to adapt the validated Nutrition Literacy Assessment Instrument for Spanish-speaking Latinos. This study was developed in two phases: adaptation and validity testing. Adaptation included translation, expert item content review, and interviews with Spanish speakers. For validity testing, 51 participants completed the Short Assessment of Health Literacy-Spanish (SAHL-S), the Nutrition Literacy Assessment Instrument in Spanish (NLit-S), and socio-demographic questionnaire. Validity and reliability statistics were analyzed. Content validity was confirmed with a Scale Content Validity Index of 0.96. Validity testing demonstrated NLit-S scores were strongly correlated with SAHL-S scores (r = 0.52, p internal consistency was excellent (Cronbach's α = 0.92). The NLit-S demonstrates validity and reliability for measuring nutrition literacy among Spanish-speakers.

Ninety-five percent of persons over the age of 65 years live in the community and benefit from community-based health and nutrition services. The purpose of this project was to evaluate diet, function, and mental health in 40 men and women aged 65 years and older who were residing in a large metropolitan community. Nutritional status was assessed using two 24-hour recalls, 5 days of food records, a food frequency, and anthropometric measurements. Participants responded to standardized activities of daily living and instrumental activities of daily living instruments and an investigator-developed, performance-based appraisal of food preparation and management. Cognition and mood were assessed using the Folstein Mini-Mental Examination and the Yesavage Depression Scale. The nutrient intakes for individuals were compared with the Recommended Dietary Allowances (RDAs) and the Food Guide Pyramid. Mean energy intake was 1,625 kcal (range = 787 to 2,910 kcal); 7 persons consumed more than 2,000 kcal. The mean vitamin and mineral intake for participants met the RDAs except for calcium, vitamin D, zinc, and magnesium intakes. The average percentages of carbohydrate, protein, and fat were 53%, 16%, and 30%, respectively. Nutritional assessments of subjects with and without congregate meals were contrasted. Six of the 13 congregate-meal participants were at nutritional risk, compared with 6 of 27 not receiving congregate meals. The interrelationships of diet, functional status, and mental health factors were examined along with recommendations for future data collection in similar studies.

Renewed Efforts Against Child Hunger (REACH) is the joint United Nations initiative to address Millennium Development Goal (MDG) 10, Target 3, i.e., to halve the proportion of underweight children under 5 years old by 2015. The United Nations Food and Agriculture Organization (FAO), the World Health Organization (WHO), the United Nations Children's Fund (UNICEF), the World Food Programme (WFP), and the International Fund for Agricultural Development (IFAD) developed and tested a facilitation mechanism to act as a catalyst for scaling up multisectoral nutrition activities. The UN-REACH partners developed pilot projects in Mauritania and Lao PDR from 2008 to 2010 and deployed facilitators to improve nutrition governance and coordination. Review missions were conducted in February 2011 to assess the REACH approach and what it achieved. The UN review mission members reviewed documents, assessed policy and management indicators, conducted qualitative interviews, and discussed findings with key stakeholders, including the most senior UN nutrition directors from all agencies. Among other UN-REACH achievements, the Prime Minister of Mauritania agreed to preside over a new National Nutrition Development Council responsible for high-level decision-making and setting national policy objectives. REACH facilitated the completion of Lao's first national Nutrition Strategy and Plan of Action and formation of the multistakeholder Nutrition Task Force. During the REACH engagement, coordination, joint advocacy, situation analysis, policy development, and joint UN programming for nutrition were strengthened in Lao PDR and Mauritania. Improvements in the nutrition governance and management mechanisms in Mauritania and Lao PDR were observed during the period of REACH support through increased awareness of nutrition as a key development objective, establishment of governmental multisectoral coordinating mechanisms, improved government capacity, and new joint UN-government nutrition

To date, few studies have focused on the nutritional status of elderly hospitalized patients with diabetes. Our aims were to explore the prevalence of malnutrition among elderly diabetes patients admitted to the hospital, and to explore the relationships between malnutrition and geriatric syndromes, diabetic complications, and clinical outcomes. A prospective, observational study including diabetes patients aged ≥65 years was carried out in a central hospital in Western China. Nutritional status was assessed using the Mini Nutritional Assessment incorporated into a comprehensive geriatric assessment. Follow up was carried out for ≤2.8 years. Of 302 participants, the prevalence of malnutrition, risk of malnutrition, and normal nutrition was 18.5%, 33.1% and 48.3%, respectively. In multivariate analysis, incontinence (odds ratio [OR] 3.17, 95% confidence interval [CI] 1.08-9.36), diabetic microvascular complications (OR 2.22, 95% CI 1.06-4.61) and activities of daily living (ADL) dependence (OR 11.6, 95% CI 5.10-26.5) were independently associated with malnutrition. Malnourished patients had longer hospital stays (P = 0.003) and higher mortality rates (P 1) than patients either at risk of malnutrition or with a normal nutritional status. Multivariate analysis also showed that malnutrition was independently associated with an increased risk of death (OR 2.86, 95% CI 1.30-6.28). The present study showed a high prevalence of malnutrition among elderly diabetes patients hospitalized for geriatric care. Considering the negative impact of malnutrition on hospital stay and mortality, adequate nutritional care should be emphasized for each elderly patient with diabetes, regardless of body mass index.

Full Text Available Abstract Background MORE Energy is a mobile health intervention which aims to reduce fatigue and improve health in airline pilots. The primary objective of this process evaluation was to assess the reach, dose delivered, compliance, fidelity, barriers and facilitators, and satisfaction of the intervention. The second objective was to investigate the associations of adherence to the intervention with compliance and with participant satisfaction. Thirdly, we investigated differences between the subgroups within the target population. Methods The intervention consisted of a smartphone application, supported by a website. It provided advice on optimal light exposure, sleep, nutrition, and physical activity, tailored to flight and personal characteristics. The reach of the intervention was determined by comparing the intervention group participants and the airline pilots who did not participate. The dose delivered was defined as the total number of participants that was sent an instruction email. Objective compliance was measured through the Control Management System of the application. To determine the fidelity, an extensive log was kept throughout the intervention period. Subjective compliance, satisfaction, barriers, facilitators, and adherence were assessed using online questionnaires. Associations between the extent to which the participants applied the advice in daily life (adherence, compliance, and satisfaction were analysed as well. Finally, outcomes of participants of different age groups and haul types were compared. Results A total of 2222 pilots were made aware of the study. From this group, 502 pilots met the inclusion criteria and did agree to participate. The reach of the study proved to be 22 % and the dose delivered was 99 %. The included pilots were randomized into the intervention group (n = 251 or the control group (n = 251. Of the intervention group participants, 81 % consulted any advice, while 17 % did this during

From this group, 502 pilots met the inclusion criteria and did agree to participate. The reach of the study proved to be 22 % and the dose delivered was 99 %. The included pilots were randomized into the intervention group (n = 251) or the control group (n = 251). Of the intervention group participants, 81 % consulted any advice, while 17 % did this during four weeks or more. Fidelity was 67 %. The

Behavioral models are developed that closely reproduced pulsive control response of two pilots using markedly different control techniques while conducting a tracking task. An intriguing find was that the pilots appeared to: 1) produce a continuous, internally-generated stick signal that they integrated in time; 2) integrate the actual stick position; and 3) compare the two integrations to either issue or cease a pulse command. This suggests that the pilots utilized kinesthetic feedback in order to sense and integrate stick position, supporting the hypothesis that pilots can access and employ the proprioceptive inner feedback loop proposed by Hess's pilot Structural Model. A Pilot Cost Index was developed, whose elements include estimated workload, performance, and the degree to which the pilot employs kinesthetic feedback. Preliminary results suggest that a pilot's operating point (parameter values) may be based on control style and index minimization.

To test the reliability and validity of the Nutrition Literacy Assessment Instrument (NLit) in adult primary care and identify the relationship between nutrition literacy and diet quality. This instrument validation study included a cross-sectional sample participating in up to 2 visits 1 month apart. A total of 429 adults with nutrition-related chronic disease were recruited from clinics and a patient registry affiliated with a Midwestern university medical center. Nutrition literacy was measured by the NLit, which was composed of 6 subscales: nutrition and health, energy sources in food, food label and numeracy, household food measurement, food groups, and consumer skills. Diet quality was measured by Healthy Eating Index-2010 with nutrient data from Diet History Questionnaire II surveys. The researchers measured factor validity and reliability by using binary confirmatory factor analysis; test-retest reliability was measured by Pearson r and the intraclass correlation coefficient, and relationships between nutrition literacy and diet quality were analyzed by linear regression. The NLit demonstrated substantial factor validity and reliability (0.97; confidence interval, 0.96-0.98) and test-retest reliability (0.88; confidence interval, 0.85-0.90). Nutrition literacy was the most significant predictor of diet quality (β = .17; multivariate coefficient = 0.10; P measuring nutrition literacy in adult primary care patients.

Present paper reports removal of radiocesium from low level waste using a modified sorbent (13X-CFC) prepared by in-situ precipitation of potassium copper hexacyanoferrate(II) inside the macropores of a synthetic zeolite. The Cs exchange isotherm of the sorbent is established and it found to follow Fruendlich absorption isotherm equation. It is varified that presence of hexacyanoferrate on zeolite facilitates rapid Cs uptake performance. This is further confirmed in laboratory scale column tests, wherein excellent Cs removal performance from low level waste simulant was observed even at higher flow rates (40 bed volumes per hour). The utility of the sorbent is established through successful demonstration in a pilot scale (50 L) trial with almost complete removal of {sup 137}Cs from more than 14,000 bed volumes of actual low level waste. The sorbent, owing to its low cost and excellent {sup 137}Cs removal performance, is expected to find application in treatment of very low active waste streams.

Agricultural food products with high nutritional value should always be preferred over food products with low nutritional value. Efforts are being made to increase nutritional value of food by incorporating dietary supplements to the food products. The same is more desirous if the nutritional value of food is increased under natural environmental conditions especially in agricultural farms. Fragmented researches have demonstrated possibilities in achieving the same. The rhizosphere is vital in this regard for not only health and nutritional status of plants but also for the microorganisms colonizing the rhizosphere. Remarkably robust composition of plant microbiome with respect to other soil environments clearly suggests the role of a plant host in discriminating its colonizers (Zancarini et al., 2012). A large number of biotic and abiotic factors are believed to manipulate the microbial communities in the rhizosphere. However, plant genotype has proven to be the key in giving the final shape of the rhizosphere microbiome (Berendsen et al., 2012; Marques et al., 2014).

Half-elemental Nutrition Mixtures for Enteral Nutrition of Children in Critical Conditions: Features of Usage and Economic Efficiency

Directory of Open Access Journals (Sweden)

2015-01-01

Full Text Available Enteral (tube nutrition has demonstrated its superiority in comparison with parenteral nutrition for patients with a preserved function of gastrointestinal tract who are in intensive care units, or ICU, and who cannot eat or are not allowed to eat by medical indications. International guidelines recommend enteral injections of mixtures for patients in critical conditions in need of nutritial support. The first twenty-four hour is considered the optimal period for starting nutritional support. It is known that costs of the enteral nutrition are much lower than costs of intravascular supply for patients who are in the ICU. The usage of special-purpose dietary products — half-elemental mixtures with high energy density — is the most physiological for children in ICU from 1 year and for adults in critical conditions.

Nutritionally promoted foods are now available at fast-food establishments. Little is known about their popularity, who is purchasing them, or their impact on dietary intake. Our study aimed to determine: how often nutritionally promoted fast foods were purchased; the demographic characteristics of people purchasing these foods; and if purchasing these foods resulted in reduced energy, and increased vegetable, content of lunches compared with those who purchased traditional fast foods. A survey collecting lunchtime fast-food purchases and demographic details was administered over two months. Nutritionally promoted products included the McDonalds' 'Heart Foundation Tick Approved' range and Subway's 'Six grams of fat or less' range. Energy and vegetable contents were estimated using information from fast-food companies' websites. Differences in demographics, energy and vegetable contents between individuals purchasing nutritionally promoted and traditional lunches were assessed using χ2 and t tests. Queensland, Australia. Lunchtime diners aged over 16 years at Subway and McDonalds. Surveys were collected from 927 respondents (58 % male, median age 25 (range 16-84) years; 73 % response rate). Only 3 % (n 24/910) of respondents who ordered a main option had purchased a nutritionally promoted item. Purchasers of nutritionally promoted foods were ∼13 years older, predominantly female (79 %), and more often reported involvement in a health-related profession (29 % v. 11 %) than purchasers of traditional foods (P < 0·05). Purchasers of nutritionally promoted foods ordered 1·5 fewer megajoules and 0·6 more vegetable servings than purchasers of traditional foods (P < 0·05). Nutritionally promoted fast foods may reduce lunchtime energy content, however these foods were infrequently chosen.

Inflammatory bowel disease (IBD) is a chronic pathology that has an outbreaks course that in recent years have seen an increase in incidence, especially at younger ages. Malnutrition is frequently associated with this condition, therefore, it is very important to ensure a right nutritional intervention, especially in pediatric patients, to ensure an optimal growth and also an improvement in the clinic. Our goal will be updated the role of nutrition in this disease and in its treatment based on the published evidence. Malnutrition in these patients is frequent and is influenced by various factors such as, decreased food intake, increased nutrient requirements, increased protein loss and malabsorption of nutrients. Therefore there should be a nutritional monitoring of all of them, in which anthropometric measurements, laboratory tests and densitometry were made to establish the needs and sufficient caloric intake tailored to each patient. The use of enteral nutrition as a treatment in Crohn’s disease with mild to moderate outbreak in child population, is amply demonstrated, has even shown to be superior to the use of corticosteroids. Therefore we can conclude by stressing that nutritional intervention is a mainstay in the management of patients with IBD, which aims to prevent and / or control disease-related malnutrition to decrease morbidity and mortality and improve quality of life.

Introduction Select units in the military have improved combat medic training by integrating their functions into routine clinical care activities with measurable improvements in battlefield care. This level of integration is currently limited to special operations units. It is unknown if regular Army units and combat medics can emulate these successes. The goal of this project was to determine whether US Army combat medics can be integrated into routine emergency department (ED) clinical care, specifically medication administration. Project Design This was a quality assurance project that monitored training of combat medics to administer parenteral medications and to ensure patient safety. Combat medics were provided training that included direct supervision during medication administration. Once proficiency was demonstrated, combat medics would prepare the medications under direct supervision, followed by indirect supervision during administration. As part of the quality assurance and safety processes, combat medics were required to document all medication administrations, supervising provider, and unexpected adverse events. Additional quality assurance follow-up occurred via complete chart review by the project lead. Data During the project period, the combat medics administered the following medications: ketamine (n=13), morphine (n=8), ketorolac (n=7), fentanyl (n=5), ondansetron (n=4), and other (n=6). No adverse events or patient safety events were reported by the combat medics or discovered during the quality assurance process. In this limited case series, combat medics safely administered parenteral medications under indirect provider supervision. Future research is needed to further develop this training model for both the military and civilian setting. Schauer SG , Cunningham C W, Fisher AD , DeLorenzo RA .

Knight, L.; Blackman, T.E.

1994-01-01

In 1989, radioactive-contaminated metal at the Rocky Flats Plant (RFP) was cleaned using a solvent paint stripper (Methylene chloride). One-third of the radioactive material was able to be recycled; two-thirds went to the scrap pile as low-level mixed waste. In addition, waste solvent solutions also required disposal. Not only was this an inefficient process, it was later prohibited by the Resource Conservation and Recovery Act (RCRA), 40 CFR 268. A better way of doing business was needed. In the search for a solution to this situation, it was decided to study the advantages of using a new technology - pelletized carbon dioxide cleaning. A proof of principle demonstration occurred in December 1990 to test whether such a system could clean radioactive-contaminated metal. The proof of principle demonstration was expanded in June 1992 with a pilot project. The purpose of the pilot project was three fold: (1) to clean metal so that it can satisfy free release criteria for residual radioactive contamination at the Rocky Flats Plant (RFP); (2) to compare two different carbon dioxide cleaning systems; and (3) to determine the cost-effectiveness of decontamination process in a production situation and compare the cost of shipping the metal off site for waste disposal. The pilot project was completed in August 1993. The results of the pilot project were: (1) 90% of those items which were decontaminated, successfully met the free release criteria , (2) the Alpheus Model 250 was selected to be used on plantsite and (3) the break even cost of decontaminating the metal vs shipping the contaminated material offsite for disposal was a cleaning rate of 90 pounds per hour, which was easily achieved

(1) To demonstrate the importance of nutrition, especially sodium restriction and increased potassium and protein intakes, in the prevention of hypertension and stroke in a pilot study involving senior citizens. (2) To design a population-based intervention in the Shimane Prefecture of Japan concerning dietary factors such as low sodium and high potassium, protein, magnesium, calcium and dietary fibre in the prevention of stroke. The intervention study was carried out at a senior citizens' residence and included general health education along with a reduction of dietary salt intake and increases in vegetable and protein, especially from seafood. Sixty-three healthy senior citizens (average age: 74.8 +/- 7.7 years) had their daily meals modified to a low sodium/potassium ratio for four weeks without their knowledge by the use of a potassium chloride substitute for salt, soy sauce and bean paste, which contains much less sodium and more potassium. Monosodium L-glutamate monohydrate used for cooking was changed to monopotassium L-glutamate monohydrate. Blood pressure was measured with the patient in the sitting position. Daily dietary sodium and potassium intakes were assessed by flame photometry from 24-hour urine specimens. Extensive intervention programs were introduced into the Shimane Prefecture, which has a population of 750,000, through health education classes for housewives, home visits by health nurses and an educational TV program for dietary improvement. The mortality from stroke was monitored for 10 years and compared with the average in Japan. The blood pressure lowering effect of reducing the dietary sodium/potassium ratio was confirmed through a pilot intervention study at the senior citizens' residence. The mortality rates for stroke in the middle-aged population from the Shimane Prefecture during the 10 years after the introduction of dietary improvement had a steeper decline in hemorrhagic, ischemic and all strokes than the average for Japan.

The aim of this research was to explore consumer perceptions of personalised nutrition and to compare these across three different levels of "medicalization": lifestyle assessment (no blood sampling); phenotypic assessment (blood sampling); genomic assessment (blood and buccal sampling). The protocol was developed from two pilot focus groups conducted in the UK. Two focus groups (one comprising only "older" individuals between 30 and 60 years old, the other of adults 18-65 yrs of age) were run in the UK, Spain, the Netherlands, Poland, Portugal, Ireland, Greece and Germany (N=16). The analysis (guided using grounded theory) suggested that personalised nutrition was perceived in terms of benefit to health and fitness and that convenience was an important driver of uptake. Negative attitudes were associated with internet delivery but not with personalised nutrition per se. Barriers to uptake were linked to broader technological issues associated with data protection, trust in regulator and service providers. Services that required a fee were expected to be of better quality and more secure. An efficacious, transparent and trustworthy regulatory framework for personalised nutrition is required to alleviate consumer concern. In addition, developing trust in service providers is important if such services to be successful. Copyright © 2013 Elsevier Ltd. All rights reserved.

The SNRB{trademark} Flue Gas Cleanup Demonstration Project was cooperatively funded by the U.S. Department of Energy (DOE), the Ohio Coal Development Office (OCDO), B&W, the Electric Power Research Institute (EPRI), Ohio Edison, Norton Chemical Process Products Company and the 3M Company. The SNRB{trademark} technology evolved from the bench and laboratory pilot scale to be successfully demonstrated at the 5-MWe field scale. Development of the SNRB{trademark} process at B&W began with pilot testing of high-temperature dry sorbent injection for SO{sub 2} removal in the 1960`s. Integration of NO{sub x} reduction was evaluated in the 1970`s. Pilot work in the 1980`s focused on evaluation of various NO{sub x} reduction catalysts, SO{sub 2} sorbents and integration of the catalyst with the baghouse. This early development work led to the issuance of two US process patents to B&W - No. 4,309,386 and No. 4,793,981. An additional patent application for improvements to the process is pending. The OCDO was instrumental in working with B&W to develop the process to the point where a larger scale demonstration of the technology was feasible. This report represents the completion of Milestone M14 as specified in the Work Plan. B&W tested the SNRB{trademark} pollution control system at a 5-MWe demonstration facility at Ohio Edison`s R. E. Burger Plant located near Shadyside, Ohio. The design and operation were influenced by the results from laboratory pilot testing at B&W`s Alliance Research Center. The intent was to demonstrate the commercial feasibility of the SNRB{trademark} process. The SNRB{trademark} facility treated a 30,000 ACFM flue gas slipstream from Boiler No. 8. Operation of the facility began in May 1992 and was completed in May 1993.

Full Text Available Objectives: Childhood obesity continues to be a problem. Children in rural populations are more likely to be overweight or obese and a lack of resources in those areas may contribute to this problem. We aimed to assess the impact of a pilot pharmacy health-care professional out-of-school time vigorous physical activity and nutrition education program on fourth and fifth graders in a rural Texas community. Methods: We conducted a prospective 12-week cohort study from August to November 2012. Thirty-three children, aged 8–11 years, in Bailey County, Texas, were enrolled in the study. Body mass index, body mass index percentile, blood pressure, waist circumference, and a diet preferences and activities knowledge survey were obtained at 0, 4, 8, and 12 weeks. Study participants completed a twice weekly physical activity and nutrition education program with exercise over weeks 1–4 with no intervention during weeks 5–12. Results: Thirty-one (94% of the 33 children, predominately Hispanic girls, completed the program. Body mass index (−0.30 (95% confidence interval, −0.44 to −0.17; P = <0.0001, body mass index percentile (−2.75 (95% confidence interval, −4.89 to −0.62; P = 0.0026, systolic blood pressure (−1.9 (95% confidence interval, −2.9 to −0.9; P = <0.0001, and waist circumference (−0.47 (95% confidence interval, −0.85 to −0.10; P = <0.0001 mean change decreased between baseline and week 12 with no intervention for 8 weeks.

AECL has developed and demonstrated the Combined Electrolysis and Catalytic Exchange (CECE) Process for detritiation of heavy water. Although CECE has been the subject of pilot-scale demonstrations by various organizations, AECL is the first to demonstrate this technology in an industrial prototype plant. AECL designed, built and operated a CECE demonstration facility under CAN/CSA N286 Quality Assurance Program. The facility was licensed by the Canadian nuclear regulator. This was a two-fold demonstration of the CECE technology - for upgrading (removal of light water) and for detritiation of heavy water. In 1998 June, AECL began operating the facility in upgrading mode. The design feed rate ranged up to 25 Mg/a for 95 mol% D 2 O feed water. After 18 months of operation in upgrading mode, the facility was reconfigured and operated for an additional 9 months from 2000 August in detritiation mode. Design capacity for detritiation was 5 Mg/a with a detritiation factor (DF) of 100. However, significantly higher DFs, up to 56 000, were demonstrated. Highlights of the detritiation demonstration were: Proven robustness of AECL's proprietary wetproofed catalyst for Liquid Phase Catalytic Exchange; Demonstration of a trickle-bed-recombiner for stoichiometric combination of deuterium and oxygen; Demonstration of electrolysis of highly tritiated heavy water; High process availability and controllability was demonstrated by a long interrupted run; Low emissions; Demonstration of high DF - up to 56 000 - a significant advantage of the CECE process over other approaches to detritiation; Validation of AECL's simulation code for the CECE process over a range of DFs from 100 to 50 000. Apart from the technology, AECL has expertise in all aspects of setting up a new detritiation facility including design, engineering, safety assessment, licensing support, project management and training. AECL is also the engineering and design contractor for a tritium removal facility that is under

Previous investigations have demonstrated that choline deficiency, manifested in low plasma-free choline concentration and hepatic injury, may develop in patients who require long-term total parenteral nutrition (TPN). Preliminary studies have suggested lecithin or choline supplementation might lead to improved visual memory in the elderly and reverse abnormal neuropsychological development in children. We sought to determine if choline-supplemented TPN would lead to improvement in neuropsychological test scores in a group of adult, choline-deficient outpatients receiving TPN. Eleven subjects (8 males, 3 females) who received nightly TPN for more than 80% of their nutritional needs for at least 12 weeks before entry in the study were enrolled. Exclusion criteria included active drug abuse, mental retardation, cerebral vascular accident, head trauma, hemodialysis or peritoneal dialysis, (prothrombin time [PT] >2x control), or acquired immune deficiency syndrome (AIDS). Patients were randomly assigned to receive their usual TPN regimen (n = 6, aged 34.0 +/- 12.6 years) over a 12-hour nightly infusion or their usual TPN regimen plus choline chloride (2 g) (n = 5, aged 37.3 +/- 7.3 years). The following neuropsychological tests were administered at baseline and after 24 weeks of choline supplementation (or placebo): Weschler Adult Intelligence Scale-Revised (WAIS-R, intellectual functioning), Weschler Memory Scale-Revised (WMS-R, two subtests, verbal and visual memory), Rey-Osterrieth Complex Figure Test (visuospatial functioning and perceptual organization), Controlled Oral Word Association Test (verbal fluency), Grooved Pegboard (manual dexterity and motor speed), California Verbal Learning Test (CVLT, rote verbal learning ability), and Trail Making Parts A & B (visual scanning, psychomotor speed and set shifting). Scores were reported in terms of standard scores including z scores and percentile ranks. Mean absolute changes in raw scores were compared between groups

A variety of organizations redistribute surplus food to low-income populations through food rescue nutrition. Why volunteers participate in these charitable organizations is unclear. The aim of this study is to document the participation and motivations of volunteers who are involved specifically in food rescue nutrition. A cross-sectional study was conducted in two phases. In phase 1, a new instrument, Motivations to Volunteer Scale, was developed and validated in 40 participants (aged ≥18 years). In phase 2, the new scale and a demographics questionnaire were administered to 300 participants who were volunteering in food pantries and churches. The pilot study showed that Motivations to Volunteer Scale exhibited an internal consistency of Cronbach's α of 0.73 (P  0.05). The scale was validated also by comparison to the Volunteer Function Inventory (r = 0.86, P social life, and altruism. The mean motivation score of the 300 volunteers was 9.15 ± 0.17. Greater motivations were observed among participants who were aged >45 years, women, Hispanics, college/university graduates, physically inactive, non-smokers, and had an income ≥ $48,000. The Motivations to Volunteer Scale is a valid tool to assess why individuals volunteer in food rescue nutrition. The extent of motivations of participants was relatively high, and the primary reason for volunteering was altruism. Health professionals should be encouraged to participate in food redistribution.

Full Text Available Kashin-Beck disease (KBD is an endemic and chronic osteochondropathy. This disease principally occurs in the Tibet Autonomous Region and in several provinces of the People's Republic of China. The etiology of the disease remains obscure although environmental factors are assumed to be involved. Diet, in particular, differentiates the rural community, affected by KBD, from the other communities (nomads and city-dwellers, who remain unaffected. In anticipation of a nutrition survey, this study aimed to measure the mineral content (Ca, P, Mg, Fe, Zn, Mn, Cu, Ni, Se, Al, Sr, Mo, Cd, As, Pb, Hg, Cr, and Co of eight Tibetan staple foods and to compare the results against two food composition tables (FCTs. Foods were sampled in twenty households selected from both an endemic and a non-endemic area of rural Tibet. Ten minerals involved in bone metabolism were measured using atomic and molecular spectrometric methods. Results revealed that a very limited number of food/constituent pairs showed a variation in mineral composition during a single year of testing for a given region. In addition, results showed significant differences in mineral content between the endemic and the non-endemic area, especially for wheat flour. Following our analysis of the mineral content of the Tibetan food samples, results were statistically compared with similar foods listed in two food composition tables: the USDA National Nutrient Database (USDA Food Search for Windows, Version 1.0, database version SR23, and the China Food Composition Table (book 1, 2nd edition. More than 50 to 60% of p-values < 0.05 were highlighted, suggesting the inappropriateness of using FCTs as a reference for nutrition surveys in rural Tibet, and emphasizing the need for analysis of traditional foods. Differences were found to be more or less marked depending on the element considered, and calcium content seemed to show the greatest difference. Although it is obviously too early for definite

Slushy weightings for the optimal pilot model. [considering visual tracking task

Science.gov (United States)

Dillow, J. D.; Picha, D. G.; Anderson, R. O.

1975-01-01

A pilot model is described which accounts for the effect of motion cues in a well defined visual tracking task. The effect of visual and motion cues are accounted for in the model in two ways. First, the observation matrix in the pilot model is structured to account for the visual and motion inputs presented to the pilot. Secondly, the weightings in the quadratic cost function associated with the pilot model are modified to account for the pilot's perception of the variables he considers important in the task. Analytic results obtained using the pilot model are compared to experimental results and in general good agreement is demonstrated. The analytic model yields small improvements in tracking performance with the addition of motion cues for easily controlled task dynamics and large improvements in tracking performance with the addition of motion cues for difficult task dynamics.

Pilot-scale tests of HEME and HEPA dissolution process

Energy Technology Data Exchange (ETDEWEB)

Qureshi, Z.H.; Strege, D.K.

1994-06-01

A series of pilot-scale demonstration tests for the dissolution of High Efficiency Mist Eliminators (HEME`s) and High Efficiency Particulate Airfilters (HEPA) were performed on a 1/5th linear scale. These fiberglass filters are to be used in the Defense Waste Processing Facility (DWPF) to decontaminate the effluents from the off-gases generated during the feed preparation process and vitrification. When removed, these filters will be dissolved in the Decontamination Waste Treatment Tank (DWTT) using 5 wt% NaOH solution. The contaminated fiberglass is converted to an aqueous stream which will be transferred to the waste tanks. The filter metal structure will be rinsed with process water before its disposal as low-level solid waste. The pilot-scale study reported here successfully demonstrated a simple one step process using 5 wt% NaOH solution. The proposed process requires the installation of a new water spray ring with 30 nozzles. In addition to the reduced waste generated, the total process time is reduced to 48 hours only (66% saving in time). The pilot-scale tests clearly demonstrated that the dissolution process of HEMEs has two stages - chemical digestion of the filter and mechanical erosion of the digested filter. The digestion is achieved by a boiling 5 wt% caustic solutions, whereas the mechanical break down of the digested filter is successfully achieved by spraying process water on the digested filter. An alternate method of breaking down the digested filter by increased air sparging of the solution was found to be marginally successful are best. The pilot-scale tests also demonstrated that the products of dissolution are easily pumpable by a centrifugal pump.

Hess, R. A.

1980-01-01

A brief survey of the more dominant analysis techniques used in closed-loop handling-qualities research is presented. These techniques are shown to rely on so-called classical and modern analytical models of the human pilot which have their foundation in the analysis and design principles of feedback control. The optimal control model of the human pilot is discussed in some detail and a novel approach to the a priori selection of pertinent model parameters is discussed. Frequency domain and tracking performance data from 10 pilot-in-the-loop simulation experiments involving 3 different tasks are used to demonstrate the parameter selection technique. Finally, the utility of this modeling approach in handling-qualities research is discussed.

Nutritional aspects of food irradiation

Energy Technology Data Exchange (ETDEWEB)

Murray, T K

1981-08-01

From the nutritional point of view the irradiation of fruits and vegetables presents few problems. It should be noted that irradiation-induced changes in the ..beta..-carotene content of papaya (not available to the Joint Expert Committee in 1976) have been demonstrated to be unimportant. The Joint Expert Committee also noted the need for more data on thiamine loss. These have been forthcoming and indicate that control of insects in rice is possible without serious loss of the vitamin. Experiments with other cereal crops were also positive in this regard. The most important evidence on the nutritional quality of irradiated beef and poultry was the demonstration that they contained no anti-thiamine properties. A point not to be overlooked is the rather serious loss of thiamine when mackerel is irradiated at doses exceeding 3 kGy. Recent evidence indicates that thiamine loss could be reduced by using a high dose rate application process. Though spices contribute little directly to the nutritional quality of the food supply they play an important indirect role. It is thus encouraging that they can be sterilized by irradiation without loss of aroma and taste and without significant loss of ..beta..-carotenes. Of future importance are the observations on single cell protein and protein-fat-carbohydrate mixtures. The reduction of net protein utilization in protein-fat mixtures may be the result of physical interaction of the components.

Nutritional support of bone marrow transplant recipients: a prospective, randomized clinical trial comparing total parental nutrition to an enteral feeding program

International Nuclear Information System (INIS)

Szeluga, D.J.

1985-01-01

Allogeneic and autologous bone marrow transplantation (BMT) have been associated with nutritionally-depleting side effects. Total parental nutrition (TPN) has become the standard, but it has not been demonstrated that TPN is the appropriate method of nutritional support. Therefore, in a prospective, randomized clinical trial TPN and enteral feeding were compared for their effectiveness in maintaining the nutritional status of patients through the first 29 post-transplant days. Nutritional assessment included measurement of serum proteins, body weight, anthropometry and isotope dilution analysis of body composition. Total body water (TBW) and extracellular fluid (ECF) were quantified by standard radioisotope dilution techniques using tritiated water and 169 ytterbium-diethylenetriaminepentaacetate, respectively as the tracers. Consenting patients 10-58 years of age were stratified by type of BMT (autologous or allogeneic) and randomized to either TPN plus ad libitum oral feeding or the individualized enteral feeding program (EFP), which included one-on-one counseling, meal-by-meal menu selection, special snacks and tube feeding. There were no differences in the rate of hematologic recovery, incidence of graft-versus-host disease, organ toxicity, length of hospitalization or survival. Therefore, the observed changes in body composition were not clinically significant. Even allowing for increased dietary service, the EFP was only half as expensive as TPN. It was concluded that TPN is not superior to the EFP and therefore, TPN should be reserved for patients who demonstrate intolerance to enteral feeding

2016-11-01

The objective of this study was to examine the perceived importance, knowledge and confidence in nutritional management in a sample of Australian medical students undertaking a 4-year postgraduate medical degree. In 2015, students in years 1-4 were anonymously surveyed to assess students' perceived importance of nutrition, and knowledge and confidence in nutritional management. A total of 131 first and second year (preclinical/yr 1-2) medical students (46% response rate) and 66 third and fourth year (clinical/yr 3-4) students (24% response rate) completed the questionnaire. Most preclinical students agreed that medical graduates should understand nutritional issues in managing cardiovascular disease (99%), type 2 diabetes (93%), coeliac disease (95%), and renal impairment (97%). However, students were limited in their confidence to demonstrate this knowledge (range of confidence: 26%-41%) for individual medical conditions. This improved for students in the clinical context of years 3 and 4, although it was still not optimal (range 26%-81%). Few year 3 and 4 students reported confidence in knowledge related to medicolegal issues, respiratory disease, nutritional guidelines and nutrition assessment (all 80%) reported confidence in the dietary management of type 2 diabetes, cardiovascular disease and coeliac disease and >60% indicated they would refer onto nutrition professionals. This cohort of postgraduate medical students recognize the importance of nutrition in disease. The number of students reporting increased confidence in nutritional management of a few select diseases where dietary management is one of the cornerstones of treatment (e.g. type 2 diabetes) rises throughout the course. However, students reported lower levels of knowledge in diseases where diet is secondary to other treatments and preventative strategies (e.g. respiratory disease). Filling the gap by integrating the nutritional management into the range of common chronic diseases during training

The Evidence for Dietary Interventions and Nutritional Supplements as Treatment Options in Multiple Sclerosis: a Review.

Science.gov (United States)

Mische, Leah J; Mowry, Ellen M

2018-03-17

This review aims to critically evaluate published studies examining diets and nutritional supplements (excepting vitamin D) for the impact on prevention and prognosis of multiple sclerosis (MS). There is a negative relationship between the Mediterranean diet and vascular disease, and vascular co-morbidities are associated with a worse MS prognosis. Low-fat, fish-based diets, sodium-restricted diets, calorie restriction, the paleo diet, and gluten-free diets have been examined, mostly in observational studies; results are inconclusive. With regard to nutritional supplements, pilot data show a possible benefit of biotin with respect to disability worsening in people with progressive MS (PMS). The best designed randomized controlled trials (RCTs) for PUFA supplementation have not shown significant impact, but several weaker RCTs have. Many other nutritional supplements have been tested, including several anti-oxidants. While some early studies show positive results, no result has been definitive. Unfortunately, there is no strong evidence for a direct benefit of any given dietary intervention on MS risk or prognosis. However, due to its relationship with vascular co-morbidities, the Mediterranean diet has the strongest rationale for employment in PwMS. Higher-quality clinical trials are needed to ascertain the possible benefits of nutritional supplements.

Principles of feeding cancer patients via enteral or parenteral nutrition during radiotherapy

International Nuclear Information System (INIS)

Fietkau, R.

1998-01-01

Background: The nutritional status of cancer patients is frequently impaired already before any therapy starts and may deteriorate even more by radio(chemo)therapy. Methods: This review describes the possibilities and risks of enteral and parenteral nutrition during radiotherapy. The indications of enteral nutrition will be derived from own results. Results: Enteral nutrition is the most preferable way of artificial long-term nutrition. In a prospective non-randomized trial we demonstrated that enteral nutrition via percutaneous endoscopic gastrostomy (PEG) not only improves the anthropometric and biochemical parameters during radio(chemo)therapy but also the quality of life of patients with advanced cancers of the head and neck. Moreover supportive use of megestrolacetate can improve the nutritional status. Parenteral nutrition is only recommended if enteral nutrition is not possible e.g. during radio(chemo)therapy of tumors of the upper gastrointestinal tract. Conclusions: Today adequate nutritional support is feasible during intensive radio(chemo)therapy. (orig.) [de

The pilot study is led by the Integration Engineering group in NASA's Launch Services Program (LSP). The Integration Engineering (IE) group is responsible for managing the interfaces between the spacecraft and launch vehicle. This pilot investigates the utility of Model-Based Systems Engineering (MBSE) with respect to managing and verifying interface requirements. The main objectives of the pilot are to model several key aspects of the Mars 2020 integrated operations and interface requirements based on the design and verification artifacts from Mars Science Laboratory (MSL) and to demonstrate how MBSE could be used by LSP to gain further insight on the interface between the spacecraft and launch vehicle as well as to enhance how LSP manages the launch service. The method used to accomplish this pilot started through familiarization of SysML, MagicDraw, and the Mars 2020 and MSL systems through books, tutorials, and NASA documentation. MSL was chosen as the focus of the model since its processes and verifications translate easily to the Mars 2020 mission. The study was further focused by modeling specialized systems and processes within MSL in order to demonstrate the utility of MBSE for the rest of the mission. The systems chosen were the In-Flight Disconnect (IFD) system and the Mass Properties process. The IFD was chosen as a system of focus since it is an interface between the spacecraft and launch vehicle which can demonstrate the usefulness of MBSE from a system perspective. The Mass Properties process was chosen as a process of focus since the verifications for mass properties occur throughout the lifecycle and can demonstrate the usefulness of MBSE from a multi-discipline perspective. Several iterations of both perspectives have been modeled and evaluated. While the pilot study will continue for another 2 weeks, pros and cons of using MBSE for LSP IE have been identified. A pro of using MBSE includes an integrated view of the disciplines, requirements, and

Use of cognitive interview techniques in the development of nutrition surveys and interactive nutrition messages for low-income populations.

The effectiveness of dietary surveys and educational messages is dependent in part on how well the target audience's information processing needs and abilities are addressed. Use of pilot testing is helpful; however, problems with wording and language are often not revealed. Cognitive interview techniques offer 1 approach to assist dietitians in understanding how audiences process information. With this method, respondents are led through a survey or message and asked to paraphrase items; discuss thoughts, feelings, and ideas that come to mind; and suggest alternative wording. As part of a US Department of Agriculture-funded nutrition education project, 23 cognitive interviews were conducted among technical community college students in North Carolina. Interview findings informed the development of tailored computer messages and survey questions. Better understanding of respondents' cognitive processes significantly improved the language and approach used in this intervention. Interview data indicated 4 problem areas: vague or ineffective instructions, confusing questions and response options, variable interpretation of terms, and misinterpretation of dietary recommendations. Interviews also provided insight into the meaning of diet-related stages of change. These findings concur with previous research suggesting that cognitive interview techniques are a valuable tool in the formative evaluation and development of nutrition surveys and materials.

We demonstrate a novel long-reach PON downstream scheme based on the regenerated pilot assisted direct-detection optical orthogonal frequency division multiplexing (DDO-OFDM) superchannel transmission. We use the optical comb source to form DDO-OFDM superchannel, and reserve the center carrier as a seed pilot. The seed pilot is further tracked and reused to generate multiple optical carriers at the local exchange. Each regenerated pilot carrier is selected to beat with an adjacent OFDM sub-band at ONU, so that the electrical bandwidth limitation can be much released compared to the conventional DDO-OFDM superchannel detection. With the proposed proof-of-concept architecture, we experimentally demonstrated a 116.7 Gb/s superchannel OFDM-PON system with transmission reach of 100 km, and 1:64 splitting ratio. We analyze the impact of carrier-to-sideband power ratio (CSPR) on system performance. The experiment result shows that, 5 dB power margin is still remained at ONU using such technique.

Recent advances in primate nutritional ecology.

Science.gov (United States)

Righini, Nicoletta

2017-04-01

Nutritional ecology seeks to explain, in an ecological and evolutionary context, how individuals choose, acquire, and process food to satisfy their nutritional requirements. Historically, studies of primate feeding ecology have focused on characterizing diets in terms of the botanical composition of the plants consumed. Further, dietary studies have demonstrated how patch and food choice in relation to time spent foraging and feeding are influenced by the spatial and temporal distribution of resources and by social factors such as feeding competition, dominance, or partner preferences. From a nutritional perspective, several theories including energy and protein-to-fiber maximization, nutrient mixing, and toxin avoidance, have been proposed to explain the food choices of non-human primates. However, more recently, analytical frameworks such as nutritional geometry have been incorporated into primatology to explore, using a multivariate approach, the synergistic effects of multiple nutrients, secondary metabolites, and energy requirements on primate food choice. Dietary strategies associated with nutrient balancing highlight the tradeoffs that primates face in bypassing or selecting particular feeding sites and food items. In this Special Issue, the authors bring together a set of studies focusing on the nutritional ecology of a diverse set of primate taxa characterized by marked differences in dietary emphasis. The authors present, compare, and discuss the diversity of strategies used by primates in diet selection, and how species differences in ecology, physiology, anatomy, and phylogeny can affect patterns of nutrient choice and nutrient balancing. The use of a nutritionally explicit analytical framework is fundamental to identify the nutritional requirements of different individuals of a given species, and through its application, direct conservation efforts can be applied to regenerate and protect specific foods and food patches that offer the opportunity of a

Parenteral nutrition in the ICU setting: need for a shift in utilization.

Science.gov (United States)

Oshima, Taku; Hiesmayr, Michael; Pichard, Claude

2016-03-01

The difficulties to feed the patients adequately with enteral nutrition alone have drawn the attention of the clinicians toward the use of parenteral nutrition, although recommendations by the recent guidelines are conflicting. This review focuses on the intrinsic role of parenteral nutrition, its new indication, and modalities of use for the critically ill patients. A recent trial demonstrated that selecting either parenteral nutrition or enteral nutrition for early nutrition has no impact on clinical outcomes. However, it must be acknowledged that the risk of relative overfeeding is greater when using parenteral nutrition and the risk of underfeeding is greater when using enteral nutrition because of gastrointestinal intolerance. Both overfeeding and underfeeding in the critically ill patients are associated with deleterious outcomes. Thus, early and adequate feeding according to the specific energy needs can be recommended as the optimal feeding strategy. Parenteral nutrition can be used to substitute or supplement enteral nutrition, if adequately prescribed. Testing for enteral nutrition tolerance during 2-3 days after ICU admission provides the perfect timing to start parenteral nutrition, if needed. In case of absolute contraindication for enteral nutrition, consider starting parenteral nutrition carefully to avoid overfeeding.

The purpose of this work was the production of a beverage with a nutritive value similar to that of milk, but available at a lower cost. A traditional beverage in Venezuela, "Chicha de Arroz" (Rice Chicha), was chosen. The various formulas studied were based on rice, non-fat milk and different kinds of soy flour, in addition to sugar, vegetable oil, vitamins, ferrous sulfate and different flavors. A product with protein and caloric values similar to those of milk was obtained. Twenty formulas were prepared and submitted to physico-chemical, microbiological and sensorial evaluations with respect to flavor, color, viscosity and stability during period of refrigeration. The most adequate formula was prepared on a pilot-plant scale. Rat assays gave the same PER results as those of casein. Consumer acceptability was tested on 1,080 school children, and showed to be greater than 95%. The stability was superior to that of milk and the cost, approximately three-fourths that of the latter. In the school-snack program of the National Institute of Nutrition, milk is now being replaced by this Chicha.

To assess how postsecondary online nutrition education courses (ONEC) are delivered, determine ONEC effectiveness, identify theoretical models used, and identify future research needs. Systematic search of database literature. Postsecondary education. Nine research articles evaluating postsecondary ONEC. Knowledge/performance outcomes and student satisfaction, motivation, or perceptions. Systematic search of 922 articles and review of 9 articles meeting search criteria. Little research regarding ONEC marketing/management existed. Studies primarily evaluated introductory courses using email/websites (before 2000), or course management systems (after 2002). None used true experimental designs; just 3 addressed validity or reliability of measures or pilot-tested instruments. Three articles used theoretical models in course design; few used theories to guide evaluations. Four quasi-experimental studies indicated no differences in nutrition knowledge/performance between online and face-to-face learners. Results were inconclusive regarding student satisfaction, motivation, or perceptions. Students can gain knowledge in online as well as in face-to-face nutrition courses, but satisfaction was mixed. More up-to-date investigations on effective practices are warranted, using theories to identify factors that enhance student outcomes, addressing emerging technologies, and documenting ONEC marketing, management, and delivery. Adequate training/support for faculty is needed to improve student experiences and faculty time management. Copyright © 2011 Society for Nutrition Education. Published by Elsevier Inc.

The purpose of this study was to develop an educational model regarding food safety and nutrition. In particular, we aimed to develop educational materials, such as middle- and high-school textbooks, a teacher's guidebook, and school posters, by applying social cognitive theory. To develop a food safety and nutrition education program, we took into account diverse factors influencing an individual's behavior, such as personal, behavioral, and environmental factors, based on social cognitive theory. We also conducted a pilot study of the educational materials targeting middle-school students (n = 26), high-school students (n = 24), and dietitians (n = 13) regarding comprehension level, content, design, and quality by employing the 5-point Likert scale in May 2016. The food safety and nutrition education program covered six themes: (1) caffeine; (2) food additives; (3) foodborne illness; (4) nutrition and meal planning; (5) obesity and eating disorders; and (6) nutrition labeling. Each class activity was created to improve self-efficacy by setting one's own goal and to increase self-control by monitoring one's dietary intake. We also considered environmental factors by creating school posters and leaflets to educate teachers and parents. The overall evaluation score for the textbook was 4.0 points among middle- and high-school students, and 4.5 points among dietitians. This study provides a useful program model that could serve as a guide to develop educational materials for nutrition-related subjects in the curriculum. This program model was created to increase awareness of nutrition problems and self-efficacy. This program also helped to improve nutrition management skills and to promote a healthy eating environment in middle- and high-school students.

Military nutrition: maintaining health and rebuilding injured tissue

Hill, Neil; Fallowfield, Joanne; Price, Susan; Wilson, Duncan

Food and nutrition are fundamental to military capability. Historical examples demonstrate that a failure to supply adequate nutrition to armies inevitably leads to disaster; however, innovative measures to overcome difficulties in feeding reap benefits, and save lives. In barracks, UK Armed Forces are currently fed according to the relatively new Pay As You Dine policy, which has attracted criticism from some quarters. The recently introduced Multi-Climate Ration has been developed specifically to deal with issues arising from Iraq and the current conflict in Afghanistan. Severely wounded military personnel are likely to lose a significant amount of their muscle mass, in spite of the best medical care. Nutritional support is unable to prevent this, but can ameliorate the effects of the catabolic process. Measuring and quantifying nutritional status during critical illness is difficult. A consensus is beginning to emerge from studies investigating the effects of nutritional interventions on how, what and when to feed patients with critical illness. The Ministry of Defence is currently undertaking research to address specific concerns related to nutrition as well as seeking to promote healthy eating in military personnel. PMID:21149358

Pilots 2.0: DIRAC pilots for all the skies

CERN Document Server

Stagni, F; McNab, A; Luzzi, C

2015-01-01

In the last few years, new types of computing infrastructures, such as IAAS (Infrastructure as a Service) and IAAC (Infrastructure as a Client), gained popularity. New resources may come as part of pledged resources, while others are opportunistic. Most of these new infrastructures are based on virtualization techniques. Meanwhile, some concepts, such as distributed queues, lost appeal, while still supporting a vast amount of resources. Virtual Organizations are therefore facing heterogeneity of the available resources and the use of an Interware software like DIRAC to hide the diversity of underlying resources has become essential. The DIRAC WMS is based on the concept of pilot jobs that was introduced back in 2004. A pilot is what creates the possibility to run jobs on a worker node. Within DIRAC, we developed a new generation of pilot jobs, that we dubbed Pilots 2.0. Pilots 2.0 are not tied to a specific infrastructure; rather they are generic, fully configurable and extendible pilots. A Pilot 2.0 can be s...

CONSIDERATIONS FOR ON-FARM RESEARCH AND DEMONSTRATION OF USEFUL FEEDING/NUTRITION PRACTICES FOR SMALL RUMINANTS IN ETHIOPIA

Arthur Louis Goetsch

2009-05-01

Full Text Available Many funding organizations view on-farm research as having greater impact than ‘on-station’ trials, a feeling shared by farmers and pastoralists because of the opportunity to see and evaluate findings first-hand.  Langston University provides technical assistance in a 5-year project supported by the U.S. Agency for International Development, entitled Ethiopia Sheep and Goat Productivity Improvement Program (ESGPIP, which includes on-farm research and demonstrations of useful feeding/nutrition practices.  The ESGPIP partners with research and extension entities throughout Ethiopia in implementing specific activities.  One effective strategy in on-farm research and demonstrations used by some partners involves group management of animals by Farmer Research Groups (FRG situated in different villages.  Four or five FRG have been used by ESGPIP implementing partners, with each consisting of 9 or 10 farmers contributing 3 or 6 animals.  Funds were provided to construct a simple barn with three pens (10 animals per pen at each FRG for group housing and feeding at night.  One or two animals per farmer were subjected to each of three feeding treatments.  Conversely, in other settings treatment imposition on individual farmers and their animals in multiple communities was most suitable.  Both approaches allow for statistical analysis of data, desirable for publication of the findings and, perhaps more importantly, true value or meaning of any differences noted.  With use of farmer-owned animals in some instances it may not be feasible to impose negative control treatments, but an appropriate common or standard supplemental feedstuff treatment allows for an adequate basis of comparison.  For sustainability, on-farm research should include input by and intimate involvement of producers and participation of local technology transfer personnel.

Full Text Available INTRODUCTION: Brazil has been called a nation in nutrition transitional because of recent increases in the prevalence of obesity and related chronic diseases. With overweight conditions already prevalent among middle-income populations, there exists a need to identify factors that influence nutrition behavior within this group. OBJECTIVE: To address this subject, a research study was implemented among middle-class adolescents attending a large private secondary school in Manaus, Amazonas, Brazil. The study determined the availability and accessibility of snack foods as well as subjects' attitudes and preferences towards, and the influence of family and friends on healthy (high-nutrient density snack choices. METHODS: The 4-stage process included: (a a nutrition expert focus group discussion that reported local nutrition problems in general and factors related to adolescent nutrition, (b an adolescent pilot survey (n=63 that solicited information about snacking preferences and habits as well as resources for nutrition information and snack money; (c a survey of various area food market sources to determine the availability and accessibility of high nutrient density snacks; and (d a follow-up adolescent survey (n=55 that measured snack food preferences and perceptions about their cost and availability. RESULTS: Results included the finding that, although affordable high nutrient density snacks were available, preferences for low nutrient density snacks prevailed. The adolescents were reportedly more likely to be influenced by and obtain nutrition information from family members than friends. CONCLUSION: From study results it is apparent that a focus on food availability will not automatically result in proper nutritional practices among adolescents. This fact and the parental influence detected are evidence of a need to involve adolescents and their parents in nutrition education campaigns to improve adolescent snack food choices.

Technologies for treatment of low level mixed wastes (LLMW) are currently being investigated by the Mixed Waste Focus Area (MWFA) of the Department of Energy (DOE). The Savannah River Technology Center (SRTC) has been chartered by the MWFA to study vitrification treatment of the wastes through an Office of Technology Development (OTD) Technical Task Plan (TTP). SRTC's efforts have included crucible-scale studies and pilot-scale testing on simulated LLMW sludges, resins, soils, and other solid wastes. Results from the crucible-scale studies have been used as the basis for the pilot-scale demonstrations. One of the streams to be investigated in fiscal year (FY) 1995 by SRTC was a mercury waste. In FY 1995, SRTC performed crucible-scale studies with mercury contaminated soil. This waste stream was selected because of the large number of DOE sites that have an inventory of contaminated or hazardous soil. More importantly, it was readily available for treatment. Pilot-scale studies were to be completed in FY 1995, but could not be completed due to a reduction in funding. Since the main driver for focusing on a mercury waste stream was to determine how the mercury could be treated, a compilation of pilot-scale tests with mercury sludges performed under the guidance of SRTC is provided in this report. The studies summarized in this report include several pilot-scale vitrification demonstrations with simulated radioactive sludges that contained mercury. The pilot-scale studies were performed at the SRTC in the Integrated Defense Waste Processing Facility (DWPF) Melter System (IDMS). The studies involved complete glass and offgas product characterization. Future pilot-scale studies with mercury streams will likely be performed with mercury contaminated soils, sediments, or sludges because of the need to dispose of this technically challenging waste stream.

Murphy, Jane L; Holmes, Joanne; Brooks, Cindy

2017-02-14

There is a growing volume of research to offer improvements in nutritional care for people with dementia living in nursing homes. Whilst a number of interventions have been identified to support food and drink intake, there has been no systematic research to understand the factors for improving nutritional care from the perspectives of all those delivering care in nursing homes. The aim of this study was to develop a research informed model for understanding the complex nutritional problems associated with eating and drinking for people with dementia. We conducted nine focus groups and five semi-structured interviews with those involved or who have a level of responsibility for providing food and drink and nutritional care in nursing homes (nurses, care workers, catering assistants, dietitians, speech and language therapists) and family carers. The resulting conceptual model was developed by eliciting care-related processes, thus supporting credibility from the perspective of the end-users. The seven identified domain areas were person-centred nutritional care (the overarching theme); availability of food and drink; tools, resources and environment; relationship to others when eating and drinking; participation in activities; consistency of care and provision of information. This collaboratively developed, person-centred model can support the design of new education and training tools and be readily translated into existing programmes. Further research is needed to evaluate whether these evidence-informed approaches have been implemented successfully and adopted into practice and policy contexts and can demonstrate effectiveness for people living with dementia.

This review provides a literature overview of new findings relating nutritional genomics and bariatric surgery. It also describes the importance of nutritional genomics concepts in personalized bariatric management. It includes a discussion of the potential role bariatric surgery plays in altering the three pillars of nutritional genomics: nutrigenetics, nutrigenomics, and epigenetics. We present studies that show the effect of each patient's genetic and epigenetic variables on the response to surgical weight loss treatment. We include investigations that demonstrate the association of single nucleotide polymorphisms with obesity phenotypes and their influence on weight loss after bariatric surgery. We also present reports on how significant weight loss induced by bariatric surgery impacts telomere length, and we discuss studies on the existence of an epigenetic signature associated with surgery outcomes and specific gene methylation profile, which may help to predict weight loss after a surgical procedure. Finally, we show articles which evidence that bariatric surgery may affect expression of numerous genes involved in different metabolic pathways and consequently induce functional and taxonomic changes in gut microbial communities. The role nutritional genomics plays in responses to weight loss after bariatric surgery is evident. Better understanding of the molecular pathways involved in this process is necessary for successful weight management and maintenance.

Attention plays a central role in cognitive processing; ineffective attention may induce accidents in flight operations. The objective of the current research was to examine military pilots' attention distributions between chasing a moving target and a stationary target. In the current research, 37 mission-ready F-16 pilots participated. Subjects' eye movements were collected by a portable head-mounted eye-tracker during tactical training in a flight simulator. The scenarios of chasing a moving target (air-to-air) and a stationary target (air-to-surface) consist of three operational phases: searching, aiming, and lock-on to the targets. The findings demonstrated significant differences in pilots' percentage of fixation during the searching phase between air-to-air (M = 37.57, SD = 5.72) and air-to-surface (M = 33.54, SD = 4.68). Fixation duration can indicate pilots' sustained attention to the trajectory of a dynamic target during air combat maneuvers. Aiming at the stationary target resulted in larger pupil size (M = 27,105, SD = 6565), reflecting higher cognitive loading than aiming at the dynamic target (M = 23,864, SD = 8762). Pilots' visual behavior is not only closely related to attention distribution, but also significantly associated with task characteristics. Military pilots demonstrated various visual scan patterns for searching and aiming at different types of targets based on the research settings of a flight simulator. The findings will facilitate system designers' understanding of military pilots' cognitive processes during tactical operations. They will assist human-centered interface design to improve pilots' situational awareness. The application of an eye-tracking device integrated with a flight simulator is a feasible and cost-effective intervention to improve the efficiency and safety of tactical training.Li W-C, Yu C-S, Braithwaite G, Greaves M.

A controlled ecological life support system (CELSS) for human habitation in preparation for future long duration space flights is considered. The success of such a system depends upon the feasibility of revitalization of food resources and the human nutritional needs which are to be met by these food resources. Edible higher plants are prime candidates for the photoautotrophic components of this system if nutritionally adequate diets can be derived from these plant sources to support humans. Human nutritional requirements information based on current knowledge are developed for inhabitants envisioned in the CELSS ground based demonstrator. Groups of plant products that can provide the nutrients are identified.

The purpose of the educational intervention was to measure changes in knowledge, perceived benefit of nutrition, and perceived self efficacy in handling side effects of chemotherapy before and after viewing a 15 minute DVD among patients with cancer. A convenience sample of 14 (4 male, 10 female, 61 ± 9 years) patients with cancer, early to chemotherapy, participated in the study. Participants completed a survey with demographic, knowledge items, and perceived health belief and self efficacy statements; viewed the DVD; and were then sent home with a one page handout. Two weeks after the nutrition education intervention, a second survey was completed including an item about tips used. Change was measured using paired t-test and wilcoxon signed rank tests. The mean score on the four knowledge items significantly increased (p informative and most (n = 11, 79%) responded that it was useful. The majority reported (n = 10, 71%) a tip they used from the DVD. This short multimedia nutrition education intervention was found primarily to increase knowledge and could form a useful component of counseling services for patients undergoing chemotherapy.

Near-Infrared Spectroscopy as a Novel Non-Invasive Tool to Assess Spiny Lobster Nutritional Condition

Rodemann, Thomas; Carter, Chris G.

2016-01-01

Rapid non-invasive monitoring of spiny lobster nutritional condition has considerable application in the established fishery, live market and prospective aquaculture. The aim of this research was to test the feasibility of near-infrared spectroscopy (NIRS) as a novel non-invasive tool to assess the nutritional condition of three lobster species. Lobster (n = 92) abdominal muscle dry matter (AMDM) and carbon content (AMC) correlated significantly with indices of nutritional condition including hepatopancreas dry matter (HPDM; rho = 0.83, 0.78), total lipid content (HPTL; rho = 0.85, 0.87) and haemolymph total protein (TP; rho = 0.89, 0.87 respectively). Abdominal muscle nitrogen content (AMN) was a poor correlate of nutritional condition. Models based on FT-NIR scanning of whole lobster tails successfully predicted AMDM, AMN and AMC (RMSECV = 1.41%, 0.35% and 0.91%; R2 = 0.75, 0.65, 0.77, respectively), and to a lower accuracy HPDM, HPTL and TP (RMSECV = 6.22%, 8.37%, 18.4 g l-1; R2 = 0.51, 0.70, 0.83, respectively). NIRS was applied successfully to assess the condition of spiny lobsters non-invasively. This pilot study paves the way for the development of crustacean condition models using portable non-invasive devices in the laboratory or in the field. PMID:27442242

Patients with locally advanced esophageal cancer can have significant dysphagia. Nutritional support during neoadjuvant therapy is often delivered via nasoenteric or percutaneous feeding tubes. These approaches do not allow for per-oral feeding. Evaluate the safety and efficacy of fully covered self-expanding metal esophageal stents for nutritional support during neoadjuvant therapy. This was a pilot, prospective study at a single tertiary center. From March 2012 to May 2013, consecutive patients with esophageal cancer eligible for neoadjuvant therapy were enrolled. Metal stents were placed prior to starting neoadjuvant therapy. Data were collected at baseline and predetermined intervals until an endpoint (surgery or disease progression). Outcomes included dysphagia grade, satisfaction of swallowing score, nutritional status (weight, serum albumin), impact on surgery, and adverse events. Fourteen stents were placed in 12 patients (59.1 ± 9.5 years, 11 men, 1 woman). Dysphagia grade (pre 3.4 ± 0.5 vs post 0.2 ± 0.4, p esophageal cancer, self-expanding metal stents are safe and effective in relieving dysphagia and maintaining nutrition. They allow patients to eat orally, thereby improving patient satisfaction. The presence of an in situ stent did not interfere with surgery.

The Japan Atomic Energy Research Institute, Chubu Electric Power Company and Ebara Corporation jointly constructed a pilot plant for electron beam flue gas treatment (dry process) capable of treating 12,000 m 3 /h (NTP) of flue gas from a coal fired boiler, at Shin-Nagoya Thermal Power Station, Chubu Electric Power Company. Various tests carried out at the plant over a period extending one year verified the followings. By appropriately controlling parameters such as electron beam dosage, flue gas temperature, and ammonia stoichiometric amount, highly efficient simultaneous SO 2 and NOx removal from flue gas was achieved under all gas conditions, equal to or more efficient than that by the highest level conventional treatment. The operation of the pilot plant was stable and trouble-free over a long term, and the operation and the process was easy to operate and control. By-products (ammonium sulfate and ammonium nitrate) produced by the flue gas treatment were proven to have superior quality, equivalent to that of market-available nitrogen fertilizers. These by-products had been registered as by-product nitrogen fertilizers. (author)

Nutritional aspects of food irradiation

International Nuclear Information System (INIS)

Murray, T.K.

1981-01-01

From the nutritional point of view the irradiation of fruits and vegetables presents few problems. It should be noted that irradiation-induced changes in the β-carotene content of papaya (not available to the Joint Expert Committee in 1976) have been demonstrated to be unimportant. The Joint Expert Committee also noted the need for more data on thiamine loss. These have been forthcoming and indicate that control of insects in rice is possible without serious loss of the vitamin. Experiments with other cereal crops were also positive in this regard. The most important evidence on the nutritional quality of irradiated beef and poultry was the demonstration that they contained no anti-thiamine properties. A point not to be overlooked is the rather serious loss of thiamine when mackerel is irradiated at doses exceeding 3 kGy. Recent evidence indicates that thiamine loss could be reduced by using a high dose rate application process. Though spices contribute little directly to the nutritional quality of the food supply they play an important indirect role. It is thus encouraging that they can be sterilized by irradiation without loss of aroma and taste and without significant loss of β-carotenes. Of future importance are the observations on single cell protein and protein-fat-carbohydrate mixtures. The reduction of net protein utilization in protein-fat mixtures may be the result of physical interaction of the components. (orig./AJ)

2018-01-01

Intensive care units (ICUs) provides intensive treatment medicine to avoid complications such as malnutrition, infection and even death. As very little is currently known about the nutritional practices in Iranian ICUs, this study attempted to assess the various aspects of current nutrition support practices in Iranian ICUs. We conducted a cross-sectional study on 150 critically ill patients at 18 ICUs in 12 hospitals located in 2 provinces of Iran from February 2015 to March 2016. Data were collected through interview with supervisors of ICUs, medical record reviews and direct observation of patients during feeding. Our study showed that hospital-prepared enteral tube feeding formulas are the main formulas used in Iranian hospitals. None of the dietitians worked exclusively an ICU and only 30% of patients received diet counselling. Regular monitoring of nutritional status, daily energy and protein intake were not recorded in any of the participating ICUs. Patients were not monitored for anthropometric measurements such as mid-arm circumference (MAC) and electrolyte status. The nasogastric tube was not switched to percutaneous endoscopic gastrostomy or jejunostomy (PEG/PEGJ) in approximately 85% of patients receiving long-term enteral nutrition (EN) support. Our findings demonstrated that the quality of nutritional care was inappropriate in Iranian ICUs and improvement of nutritional care services within Iranian ICUs is necessary. PMID:29713622

Nutrition support of the pediatric patient with AIDS.

Bentler, M; Stanish, M

1987-04-01

Maintaining optimal nutrition in the pediatric patient with Acquired Immune Deficiency Syndrome (AIDS) is challenging, but it may be one of the most effective therapies. Patients experience numerous complications that compromise nutritional status. Infection, fever, diarrhea, feeding problems, and decreased intake all contribute to malnutrition, which in turn predisposes the patient even more to infection and malabsorption. Nutrition assessment should be done routinely so that new problems may be identified and treated. High-calorie, high-protein feedings, vitamin supplementation, and, when necessary, gavage feedings or parenteral nutrition are recommended to improve nutritional status and prevent further deficits. Maintaining optimal nutrition in the pediatric patient with Acquired Immune Deficiency Syndrome (AIDS) poses a significant challenge to the health care team. Patients may experience numerous complications that compromise nutritional status. The patient is at high risk for opportunistic infections, especially of the lungs, central nervous system, gastrointestinal (GI) tract, and skin. Such infections are common causes of morbidity and mortality. Impaired nutritional status may further impair the patient's immunocompetence. A study by Kotler and Gaety demonstrated severe progressive malnutrition in adult AIDS patients, with the lowest measures of lean body mass occurring in those patients close to death at the time of the study. While no studies of children with AIDS have been done to date, we have subjectively observed feeding problems, weight loss, and malnutrition in most of the patients we have seen.

Alterations of nutritional status: impact of chemotherapy and radiation therapy

International Nuclear Information System (INIS)

Donaldson, S.S.; Lenon, R.A.

1979-01-01

The nutritional status of a cancer patient may be affected by the tumor, the chemotherapy and/or radiation therapy directed against the tumor, and by complications associated with that therapy. Chemotherpay-radiotherapy is not confined exclusively to malignant cell populations; thus, normal tissues may also be affected by the therapy and may contribute to specific nutritional problems. Impaired nutrition due to anorexia, mucositis, nausea, vomiting, and diarrhea may be dependent upon the specific chemotherapeutic agent, dose, or schedule utilized. Similar side effects from radiation therapy depend upon the dose, fractionation, and volume irradiated. When combined modality treatment is given the nutritional consequences may be magnified. Prospective, randomized clinical trials are underway to investigate the efficacy of nutritional support during chemotherapy-radiotherapy on tolerance to treatment, complications from treatment, and response rates to treatment. Preliminary results demonstrate that the administration of total parenteral nutrition is successful in maintaining weight during radiation therapy and chemotherapy, but that weight loss occurs after discontinuation of nutritional support. Thus, longterm evaluation is mandatory to learn the impact of nutritional support on survival, diease-free survival, and complication rates, as well as on the possible prevention of morbidity associated with aggressive chemotherapy-radiation therapy

To examine the nutrition and young child feeding (YCF) education and training of nurses in public health clinics of Ghana's Komenda-Edina-Eguafo-Abrem region (KEEA) in relation to global health guidelines, and how nurses served as educators for caregivers with children aged 0-5 years. A qualitative study of semi-structured one-on-one and group interviews (n 21) following a questionnaire of closed- and open-ended questions addressing child feeding, nutrition and global health recommendations. Interviews were conducted in English, audio-recorded, transcribed and coded. Descriptive data were tabulated. Content analysis identified themes from open-ended questions. KEEA public health clinics (n 12). Nurses (n 41) purposefully recruited from KEEA clinics. A model capturing nurses' nutrition and YCF education emerged with five major themes: (i) adequacy of nurses' basic knowledge in breast-feeding, complementary feeding, iron-deficiency anaemia, YCF and hygiene; (ii) nurses' delivery of nutrition and YCF information; (iii) nurses' evaluation of children's health status to measure education effectiveness; (iv) nurses' perceived barriers of caregivers' ability to implement nutrition and YCF education; and (v) a gap in global health recommendations on YCF practices for children aged 2-5 years. Nurses demonstrated adequate nutrition and YCF knowledge, but reported a lack of in-depth nutrition knowledge and YCF education for children 2-5 years of age, specifically education and knowledge of YCF beyond complementary feeding. To optimize child health outcomes, a greater depth of nutrition and YCF education is needed in international health guidelines.

2014-01-01

Palm oil is the major oil produced, with annual world production in excess of 50 million tonnes. About 85% of global palm oil produced is used in food applications. Over the past three decades, research on nutritional benefits of palm oil have demonstrated the nutritional adequacy of palm oil and its products, and have resulted in transitions in the understanding these attributes. Numerous studies have demonstrated that palm oil was similar to unsaturated oils with regards to effects on blood lipids. Palm oil provides a healthy alternative to trans-fatty acid containing hydrogenated fats that have been demonstrated to have serious deleterious effects on health. The similar effects of palm oil on blood lipids, comparable to other vegetable oils could very well be due to the structure of the major triglycerides in palm oil, which has an unsaturated fatty acid in the stereospecific numbers (sn)-2 position of the glycerol backbone. In addition, palm oil is well endowed with a bouquet of phytonutrients beneficial to health, such as tocotrienols, carotenoids, and phytosterols. This review will provide an overview of studies that have established palm oil as a balanced and nutritious oil. PMID:25821404

Phase 1 implementation of nutrition screening in a Dublin acute teaching hospital

LENUS (Irish Health Repository)

2014-01-01

Nutrition Screening Week results from 2010 and 2011 indicated that one in three to four patients admitted to Irish Hospitals are at risk of disease-related malnutrition, 74-75% of whom are at high risk1. Nutrition screening tools are used to screen for malnutrition risk. One such tool, the Malnutrition Universal Screening Tool (MUST)2 is a practical, easy to use tool that often takes ≤5 minutes to complete. MUST has been validated across care settings and across patient populations, and has been recommended for use in Irish Hospitals by the Department of Health and Children as part of standard care3. The National Institute for Health and Clinical Excellence in the UK has demonstrated significant financial savings associated with the use of routine nutrition screening, in part due to reduced length of hospital stay4. The Irish Society for Clinical Nutrition and Metabolism (IrSPEN) has also demonstrated this5

Nutritional assessment with body composition measurements

International Nuclear Information System (INIS)

Shizgal, H.M.

1987-01-01

The measurement of body composition by multiple isotope dilution provides an accurate and precise measure of both the nutritional state and the response to nutritional support. A multiple isotope dilution technique has been developed that permits measurement of the three major components of body composition: body fat, extracellular mass (ECM), and body cell mass (BCM). Normal body composition was defined by data obtained in 25 healthy volunteers. Malnutrition is characterized by a loss of BCM and an expansion of the ECM, and as a result the lean body mass is not significantly different from normal. The loss of body weight with malnutrition therefore often reflects the loss of body fat. The utility of body composition measurements was demonstrated by determining the effect of total parenteral nutrition on body composition to determine the relationship between caloric intake and the change in the BCM. A statistically significant relationship was developed which demonstrated that a caloric intake in the range of 30-40 cal/kg/day is required for maintenance. To restore a depleted or malnourished BCM requires a caloric intake in excess of that required for maintenance. The measurement of body composition by multiple isotope dilution is complex and time consuming, and requires specialized laboratory facilities and specially trained personnel. As a result, these measurements are not suited for routine patient management, but should rather be reserved for research purposes

Helicopter pilots' views of air traffic controller responsibilities: a mismatch.

Science.gov (United States)

Martin, Daniel; Nixon, Jim

2018-02-21

Controllers and pilots must work together to ensure safe and efficient helicopter flight within the London control zone. Subjective ratings of pilot perception of controller responsibility for five key flight tasks were obtained from thirty helicopter pilots. Three types of airspace were investigated. Results indicate that there is variation in pilot understanding of controller responsibility compared to the formal regulations that define controller responsibility. Significant differences in the perception of controller responsibility were found for the task of aircraft separation in class D airspace and along helicopter routes. Analysis of the patterns of response suggests that task type rather than the airspace type may be the key factor. Results are framed using the concept of a shared mental model. This research demonstrates that pilots flying in complex London airspace have an expectation of controller responsibility for certain flight tasks, in certain airspace types that is not supported by aviation regulation. Practitioner Summary: The responsibility for tasks during flight varies according to the flight rules used and airspace type. Helicopter pilots may attribute responsibility to controllers for tasks when controllers have no responsibility as defined by regulation. This variation between pilot perceptions of controller responsibility could affect safety within the London control zone.

Recommendations to screen and counsel for lifestyle behaviors can be challenging to implement during well-child visits in the primary care setting. A practice intervention was piloted using the Family Nutrition and Physical Activity (FNPA) Screening Tool paired with a motivational interviewing (MI)-based counseling tool during well-child visits. Acceptability and feasibility of this intervention were assessed. Its impact on parent-reported obesigenic behavior change and provider efficacy in lifestyle counseling were also examined. This was an observational study in a pediatric primary care office. During well-child visits of 100 patients (ages 4-16 years), the FNPA tool was implemented and providers counseled patients in an MI-consistent manner based on its results. Duration of implementation, patient satisfaction of the intervention, and success of stated lifestyle goals were measured. Provider self-efficacy and acceptability were also surveyed. The FNPA assessment was efficient to administer, requiring minutes to complete and score. Patient acceptability was high, ranging from 4.0 to 4.8 on a 5-point scale. Provider acceptability was good, with the exception of duration of counseling; self-efficacy in assessing patient "readiness for change" was improved. Parent-reported success of primary lifestyle goal was 68% at 1 month and 46% at 6 months. The FNPA assessment with an MI-based counseling tool shows promise as an approach to identify and address obesigenic behaviors during pediatric well-child visits. It has the potential to improve provider efficacy in obesity prevention and also influence patient health behaviors, which can possibly impact childhood excessive weight gain. After refinement, this practice intervention will be used in a larger trial.

In the last 20 years, Public Health Nutrition focused mainly on the qualitative aspects which may influence the onset of chronic diseases, quality of life, physical and mental performance and life expectancy. This applied knowledge organised as part of preventive and health promotion programs led to the development of Community Nutrition. The aim of Community Nutrition actions is to adequate lifestyles related to food consumption patterns in order to improve the quality of life and contribute to health promotion of the population in the community where programs and services are delivered. Key functions to develop in a Community Nutrition Unit consist in the identification and assessment of nutrition problems in the community as well as the design, implementation and evaluation of intervention programs by means of appropriate strategies. These should aim at different populations groups and settings, such as work places, schools, high risk groups or the general public. Nowadays, Community Nutrition work efforts should focus on three main aspects: nutrition education in schools and in the community; food safety and food security and the development and reinforcement of food preparation skills across all age groups. Social catering services, either in schools, the work place or at the community level, need to ensure adequate nutritional supply, provide foods contributing to healthy eating practices as well as to enhance culinary traditions and social learning. Food safety and food security have become a top priority in Public Health. The concepts referes to the availability of food safe and adequate as well as in sufficient amount in order to satisfy nutrition requirements of all individuals in the community. Social changes along new scientific developments will introduce new demands in Community Nutrition work and individual dietary counselling will become a key strategy. In order to face new challenges, community nutrition pactitioners require a high quality

The demonstration of the IGRS approach conducted at SWMU 143 on the White Sands Missile Range has provided information needed to complete a technical performance assessment and cost analysis of the technology. At least 70% of the Cr(VI) present in contaminated sediment at the site was reduced, thus verifying the effectiveness of the approach. Most of the treatment occurred in a zone located from approximately4 to 10 ft below ground surface, which appears to be a higher permeability interval. A deeper zone from approximately10 to 16 ft that contains lower levels of contamination was essentially unaffected. The deeper zone is somewhat finer grained and has a higher clay content and is, thus, less permeable. It appears that most of the treatment gas was channeled through the higher, more-permeable zone and the lower zone was bypassed. Treatment of the lower zone could probably be accomplished, however, if a second injection well were installed and screened across the zone so that treatment gas could be forced into this interval. The amount of H 2 S consumed during the test exceeded the amount predicted by the laboratory treatability study. In addition, the levels of H 2 S observed at the extraction wells were relatively low, even though a significant level of treatment was observed at the site. It is inferred that interfering reactions or slower reaction kinetics are the likely source of consumption of extra H 2 S observed in the field. Future laboratory work will be undertaken to investigate the nature of these chemical reactions and the reaction rates associated with the gaseous reduction of Cr(VI) in soils. Elucidation of these effects may reveal methods for improving the effectiveness of the technology and reducing unit costs. A life-cycle cost model was developed for the technology based on demonstration information (Hogan 1998). This model suggests that the technology should compare favorably with excavation from a cost basis for larger sites, especially when

Full Text Available Melanie Paul, Melanie Baker, Robert N Williams, David J Bowrey Department of Surgery, Leicester Royal Infirmary, Leicester, UK Background and aims: Provision of adequate nutrition after esophagectomy remains a major challenge. The aims of this review were to describe the challenges facing this patient population and to determine the evidence base underpinning current nutritional and dietetic interventions after esophagectomy. Methods: Medline, Embase and CINAHL databases were searched for English language publications of the period 1990–2016 reporting on the outcome of nutritional or dietetic interventions after esophagectomy or patient-related symptoms. Results: Four studies demonstrated that early reintroduction of oral fluids was safe and was associated with a shorter hospital stay and ileus duration. One of three studies comparing in-hospital enteral nutrition against usual care showed that enteral feeding was well tolerated and was associated with a shorter hospital stay. Eight studies comparing enteral with parenteral nutrition showed similar surgical complication rates. Enteral feeding was associated with a shorter duration of ileus and lower health care costs. In hospital, all types of enteral access (nasoenteral, jejunostomy were equivalent in their safety profiles. Cohort studies indicate that technical (tube dysfunction and feed (diarrhea, distention problems were common with jejunostomies but are easily managed. The mortality risk associated with jejunostomy in hospital is 0.2% (reported range 0%–1%, principally due to small bowel ischemia. There have been no reports of serious jejunostomy complications in patients receiving home feeding. One study demonstrated the advantages of home feeding in weight, muscle and fat preservation. Studies reporting 12 months or more after esophagectomy indicate a high frequency of persistent symptoms, dumping syndrome 15%–75% (median 46%, dysphagia 11%–38% (median 27%, early satiety 40%–90

The prevalence of disease-related malnutrition in Western European hospitals is estimated to be about 30%. There is no consensus whether poor nutritional status causes poorer clinical outcome or if it is merely associated with it. The intention with all forms of nutrition support is to increase uptake of essential nutrients and improve clinical outcome. Previous reviews have shown conflicting results with regard to the effects of nutrition support. To assess the benefits and harms of nutrition support versus no intervention, treatment as usual, or placebo in hospitalised adults at nutritional risk. We searched Cochrane Central Register of Controlled Trials (CENTRAL) in the Cochrane Library, MEDLINE (Ovid SP), Embase (Ovid SP), LILACS (BIREME), and Science Citation Index Expanded (Web of Science). We also searched the World Health Organization International Clinical Trials Registry Platform (www.who.int/ictrp); ClinicalTrials.gov; Turning Research Into Practice (TRIP); Google Scholar; and BIOSIS, as well as relevant bibliographies of review articles and personal files. All searches are current to February 2016. We include randomised clinical trials, irrespective of publication type, publication date, and language, comparing nutrition support versus control in hospitalised adults at nutritional risk. We exclude trials assessing non-standard nutrition support. We used standard methodological procedures expected by Cochrane and the Cochrane Hepato-Biliary Group. We used trial domains to assess the risks of systematic error (bias). We conducted Trial Sequential Analyses to control for the risks of random errors. We considered a P value of 0.025 or less as statistically significant. We used GRADE methodology. Our primary outcomes were all-cause mortality, serious adverse events, and health-related quality of life. We included 244 randomised clinical trials with 28,619 participants that met our inclusion criteria. We considered all trials to be at high risk of bias. Two

Pilot implementations appear to promise a way to extend prototyping from...... the laboratory to the field, thereby allowing users to experience a system design under realistic conditions and developers to get feedback from realistic use while the design is still malleable. We characterize pilot implementation, contrast it with prototyping, propose a iveelement model of pilot...... implementation and provide three empirical illustrations of our model.

The purpose of this study was to test the feasibility and efficacy of implementing a 4-week menu plan combined with individual counselling among people with type 2 diabetes. A 12-week pilot study with a pretest and post-test design was conducted among 15 participants with type 2 diabetes. The menu plan incorporated the overall recommendations of the Canadian Diabetes Association nutrition therapy guidelines and considered factors such as the accessibility, availability and acceptability of foods. Change in glycated hemoglobin (A1C) was the primary outcome, and secondary outcomes were changes in serum lipid, anthropometric and dietary measures. Mean (±SD) age of the participants was 59.3±9.9 years, and duration of diabetes was 8.1±8.3 years. After the program, A1C decreased by 1.0%±0.86% (p1.9 days a week and attended, on average, 4 of 6 counselling sessions. Menu planning and individual counselling were demonstrated to be feasible and effective for diabetes management, and they represent a simple and practical approach to implement the nutritional recommendations for diabetes in Canada.

The Supplemental Nutrition Assistance Program: Analysis of Program Administration and Food Law Definitions.

Science.gov (United States)

Pomeranz, Jennifer L; Chriqui, Jamie F

2015-09-01

Under the current version of the Supplemental Nutrition Assistance Program (SNAP), participants can purchase virtually any food or beverage (collectively, food). Research indicates that SNAP recipients may have worse dietary quality than income-eligible nonparticipants. Policymakers have urged the U.S. Department of Agriculture (USDA) to pilot SNAP purchasing restrictions intended to support a healthier diet, and state legislators have proposed similar bills. The USDA rejected these invitations, stating that it would be administratively and logistically difficult to differentiate among products, amid other concerns. However, the USDA's Dietary Guidelines for Americans and the Supplemental Nutrition Program for Women, Infants, and Children (WIC) do just that. Further, state governments define and differentiate among foods and beverages for tax purposes. This paper reviews several factors intended to inform future policy decisions: the science indicating that SNAP recipients have poorer diet quality than income-eligible nonparticipants; the public's support for revising the SNAP program; federal, state, and city legislators' formal proposals to amend SNAP based on nutrition criteria and the USDA's public position in opposition to these proposals; state bills to amend eligible foods purchasable with SNAP benefits; state retail food tax laws; and the retail administration and program requirements for both WIC and SNAP. The paper finds that the government has a clear ability to align SNAP benefits with nutrition science and operationalize this into law. Copyright © 2015 American Journal of Preventive Medicine.

Carretta, T R; Perry, D C; Ree, M J

1996-01-01

Situational awareness (SA) is a skill often deemed essential to pilot performance in both combat and noncombat flying. A study was conducted to determine if SA in U.S. Air Force F-15 pilots could be predicted. The participants were 171 active duty F-15 A/C pilots who completed a test battery representative of various psychological constructs proposed or demonstrated to be valid for the prediction of performance in a wide variety of military and civilian jobs. These predictors encompassed measures of cognitive ability, psychomotor ability, and personality. Supervisor and peer ratings of SA were collected. Supervisors and peers showed substantial agreement on the SA ratings of the pilots. The first unrotated principle component extracted from the supervisor and peer ratings accounted for 92.5% of the variability of ratings. The unrotated first principal component served as the SA criterion. Flying experience measured in number of F-15 hours was the best predictor of SA. After controlling for the effects of F-15 flying hours, the measures of general cognitive ability based on working memory, spatial reasoning, and divided attention were found to be predictive of SA. Psychomotor and personality measures were not predictive. With additional F-15 flying hours it is expected that pilots would improve their ratings of SA.

Green marketing in the Massachusetts electric company retail competition pilot program

1997-10-01

With electric industry restructuring initiatives being introduced on the state and federal levels, retail access pilot programs serve an important function for examining competitive market issues, as well as marketing strategies and customer reactions to different power supply options. The experience gained through these pilots provides important insights into future power market operations, including the market for green power. The Massachusetts Electric Company`s (MECo`s) Choice: New England pilot for residential and small-business customers was a voluntary program developed primarily to test the billing and metering logistics that distribution companies will need in the competitive market. The pilot also offered a preview of program implementation and marketing under customer choice. It was the first retail competition pilot to explicitly include green power options in program design. The MECo pilot`s energy suppliers were selected through the issuance of a request for proposals (RFP). Respondents were asked to submit bids in one or more of three energy supply categories-price, green, and other options. These options were developed by the pilot administrator through internal meetings, discussions with state officials and other stakeholders, and a review of information from other similar pilots. For the green option, the pilot administrator did not establish a green standard. Instead, suppliers were allowed to submit offers that promoted environmental stewardship. Customer response to the different green options are reported. The pilot results clearly demonstrate that, in a competitive situation, there is interest in a variety of energy supply options, including green options. 2 tabs.

This study evaluated the impact of nutritional education on knowledge, attitude and practices (KAP) of mothers concerning infants and young children feeding and their children's nutritional status in two semi-urban communities of south-west Nigeria. This is a community intervention study. We recruited 150 mothers of children aged 0-18 months independently from the intervention and control communities through a multi-stage sampling technique. We collected data with the aid of an interviewer-administered questionnaire at baseline and at six months after intervention from both communities to obtain information on feeding of infants and young children. In addition, we measured weights and heights of recruited children. Intervention involved group counselling of mothers and food demonstrations at designated health facilities. Data analysis for quantitative data was done using Epi-Info software, and for qualitative data, content analysis of major themes was used. Before intervention, recruited mothers and their children from the two communities were comparable in terms of all the parameters assessed (P>0.05 in all cases). After six months of intervention, mothers who had nutritional education demonstrated better knowledge and attitudes to key infant and young children feeding recommendations. There was also limited improvement in feeding practices. Mothers from the intervention community exclusively breastfed their infants longer with mean age at introduction of complementary foods at 5.3 months compared to 4.5 months in the control community (Pchildren longer (Pchildren. In this study, nutritional education of mothers only had positive impact on their level of KAP on infant and young children feeding.

which missing dichotomous data were imputed as best- and worst-case scenarios; 3) all trials were combined to assess mortality; 4) effects were estimated by absolute risk reductions. Thirty-seven trials were identified; only one was at low risk of bias. Most of the analyses failed to find any significant differences. The significant findings that were found were the following: 1) icteric medical patients receiving parenteral nutrition had a reduced serum bilirubin (mean difference (MD) -2.86 mg%, 95% CI -3.82 mg% to -1.89 mg%, 3 trials) and better nitrogen balance (MD 3.60 g/day, 95% CI 0.86 g/day to 6.34 g/day, 1 trial); 2) surgical patients receiving parenteral nutrition had a reduced incidence of postoperative ascites only in the fixed-effect model (RR 0.65, 95% CI 0.48 to 0.87, 2 trials, I(2) = 70%) and one trial demonstrated a reduction in postoperative complications, especially infections (pneumonia in particular); 3) enteral nutrition may have improved nitrogen balance in medical patients (although a combination of the three trials was not possible); 4) one surgical trial of enteral nutrition found a reduction in postoperative complications; and 5) oral nutritional supplements had several effects in medical patients (reduced occurrence of ascites (RR 0.57, 95% CI 0.37 to 0.88, 3 trials), possibly (significant differences only seen in the fixed-effect model) reduced rates of infection (RR 0.49, 95% CI 0.24 to 0.99, 3 trials, I(2) = 14%), and improved resolution of hepatic encephalopathy (RR 3.75, 95% CI 1.15 to 12.18, 2 trials, I(2) = 79%). While there was no overall effect of the supplements on mortality in medical patients, the one low risk of bias trial found an increased risk of death in the recipients of the supplements.

The demonstration of the IGRS approach conducted at SWMU 143 on the White Sands Missile Range has provided information needed to complete a technical performance assessment and cost analysis of the technology. At least 70% of the Cr(VI) present in contaminated sediment at the site was reduced, thus verifying the effectiveness of the approach. Most of the treatment occurred in a zone located from {approximately}4 to 10 ft below ground surface, which appears to be a higher permeability interval. A deeper zone from {approximately}10 to 16 ft that contains lower levels of contamination was essentially unaffected. The deeper zone is somewhat finer grained and has a higher clay content and is, thus, less permeable. It appears that most of the treatment gas was channeled through the higher, more-permeable zone and the lower zone was bypassed. Treatment of the lower zone could probably be accomplished, however, if a second injection well were installed and screened across the zone so that treatment gas could be forced into this interval. The amount of H{sub 2}S consumed during the test exceeded the amount predicted by the laboratory treatability study. In addition, the levels of H{sub 2}S observed at the extraction wells were relatively low, even though a significant level of treatment was observed at the site. It is inferred that interfering reactions or slower reaction kinetics are the likely source of consumption of extra H{sub 2}S observed in the field. Future laboratory work will be undertaken to investigate the nature of these chemical reactions and the reaction rates associated with the gaseous reduction of Cr(VI) in soils. Elucidation of these effects may reveal methods for improving the effectiveness of the technology and reducing unit costs. A life-cycle cost model was developed for the technology based on demonstration information (Hogan 1998). This model suggests that the technology should compare favorably with excavation from a cost basis for larger sites

Nutrition clubs (NC) operate in community settings and provide members with nutrition education and meal replacements for weight management. NC are owned and operated by distributors of Herbalife products. There are over 6200 NC in the US, but there has been no independent assessment of the association of these NC with biomarkers of health. We conducted a cross-sectional pilot study to compare the health status of 100 NC members to 100 community-matched controls (CC) in the greater Boston area. Each CC was matched to a NC member for community of residence (zip code), age category, gender, BMI category, race/ethnicity, education level (category), and readiness to make health changes. Measures obtained included cardio-metabolic risk factors, body composition, markers of nutritional status, reported health status, dietary intake, physical activity, sleep and depression. Participants were predominantly female (64%) and Hispanic (73%). NC members had significantly lower fasting insulin (P Herbalife NC membership for themselves and their families. A higher percentage of NC members (86%) compared to CC (32%) reported being in much better or somewhat better health compared to a year ago (P Herbalife NC membership was positively associated with perceived health and measured cardiometabolic benefits. However, causality cannot be inferred from these findings.

2007-01-01

This paper reports on the combined solar photo-Fenton/biological treatment of an industrial effluent (initial total organic carbon, TOC, around 500 mg L -1 ) containing a non-biodegradable organic substance (α-methylphenylglycine at 500 mg L -1 ), focusing on pilot plant tests performed for design of an industrial plant, the design itself and the plant layout. Pilot plant tests have demonstrated that biodegradability enhancement is closely related to disappearance of the parent compound, for which a certain illumination time and hydrogen peroxide consumption are required, working at pH 2.8 and adding Fe 2+ = 20 mg L -1 . Based on pilot plant results, an industrial plant with 100 m 2 of CPC collectors for a 250 L/h treatment capacity has been designed. The solar system discharges the wastewater (WW) pre-treated by photo-Fenton into a biotreatment based on an immobilized biomass reactor. First, results of the industrial plant are also presented, demonstrating that it is able to treat up to 500 L h -1 at an average solar ultraviolet radiation of 22.9 W m -2 , under the same conditions (pH, hydrogen peroxide consumption) tested in the pilot plant

Enteral and Parenteral Nutrition in the Perioperative Period: State of the Art

Abunnaja, Salim; Cuviello, Andrea; Sanchez, Juan A.

2013-01-01

Nutritional support of surgical and critically ill patients has undergone significant advances since 1936 when Studley demonstrated a direct relationship between pre-operative weight loss and operative mortality. The advent of total parenteral nutrition followed by the extraordinary progress in parenteral and enteral feedings, in addition to the increased knowledge of cellular biology and biochemistry, have allowed clinicians to treat malnutrition and improve surgical patient’s outcomes. We reviewed the literature for the current status of perioperative nutrition comparing parenteral nutrition with enteral nutrition. In a surgical patient with established malnutrition, nutritional support should begin at least 7–10 days prior to surgery. Those patients in whom eating is not anticipated beyond the first five days following surgery should receive the benefits of early enteral or parenteral feeding depending on whether the gut can be used. Compared to parenteral nutrition, enteral nutrition is associated with fewer complications, a decrease in the length of hospital stay, and a favorable cost-benefit analysis. In addition, many patients may benefit from newer enteral formulations such as Immunonutrition as well as disease-specific formulations. PMID:23429491

Over a decade since the completion of the human genome sequence, the promise of personalised nutrition available to all has yet to become a reality. While the definition was originally very gene-focused, in recent years, a model of personalised nutrition has emerged with the incorporation of dietary, phenotypic and genotypic information at various levels. Developing on from the idea of personalised nutrition, the concept of targeted nutrition has evolved which refers to the delivery of tailored dietary advice at a group level rather than at an individual level. Central to this concept is metabotyping or metabolic phenotyping, which is the ability to group similar individuals together based on their metabolic or phenotypic profiles. Applications of the metabotyping concept extend from the nutrition to the medical literature. While there are many examples of the metabotype approach, there is a dearth in the literature with regard to the development of tailored interventions for groups of individuals. This review will first explore the effectiveness of personalised nutrition in motivating behaviour change and secondly, examine potential novel ways for the delivery of personalised advice at a population level through a metabotyping approach. Based on recent findings from our work, we will demonstrate a novel strategy for the delivery of tailored dietary advice at a group level using this concept. In general, there is a strong emerging evidence to support the effectiveness of personalised nutrition; future work should ascertain if targeted nutrition can motivate behaviour change in a similar manner.

There is a new merging of health economics and nutrition disciplines to assess the impact of diet on health and disease prevention and to characterise the health and economic aspects of specific changes in nutritional behaviour and nutrition recommendations. A rationale exists for developing the field of nutrition economics which could offer a better understanding of both nutrition, in the context of having a significant influence on health outcomes, and economics, in order to estimate the absolute and relative monetary impact of health measures. For this purpose, an expert meeting assessed questions aimed at clarifying the scope and identifying the key issues that should be taken into consideration in developing nutrition economics as a discipline that could potentially address important questions. We propose a first multidisciplinary outline for understanding the principles and particular characteristics of this emerging field. We summarise here the concepts and the observations of workshop participants and propose a basic setting for nutrition economics and health outcomes research as a novel discipline to support nutrition, health economics and health policy development in an evidence and health-benefit-based manner.

SkyMine Carbon Mineralization Pilot Project

Energy Technology Data Exchange (ETDEWEB)

Christenson, Norm; Walters, Jerel

2014-12-31

This Topical Report addresses accomplishments achieved during Phase 2b of the SkyMine® Carbon Mineralization Pilot Project. The primary objectives of this project are to design, construct, and operate a system to capture CO2 from a slipstream of flue gas from a commercial coal-fired cement kiln, convert that CO2 to products having commercial value (i.e., beneficial use), show the economic viability of the CO2 capture and conversion process, and thereby advance the technology to the point of readiness for commercial scale demonstration and deployment. The overall process is carbon negative, resulting in mineralization of CO2 that would otherwise be released into the atmosphere. The project will also substantiate market opportunities for the technology by sales of chemicals into existing markets, and identify opportunities to improve technology performance and reduce costs at the commercial scale. The project is being conducted in two phases. The primary objectives of Phase 1 were to evaluate proven SkyMine® process chemistry for commercial pilot-scale operation and complete the preliminary design for the pilot plant to be built and operated in Phase 2, complete a NEPA evaluation, and develop a comprehensive carbon life cycle analysis. The objective of Phase 2b was to build the pilot plant to be operated and tested in Phase 2c.

Giffin, W. C.; Rockwell, T. H.; Smith, P. J.

1984-01-01

Experiments on pilot decision making are described. The development of models of pilot decision making in critical in flight events (CIFE) are emphasized. The following tests are reported on the development of: (1) a frame system representation describing how pilots use their knowledge in a fault diagnosis task; (2) assessment of script norms, distance measures, and Markov models developed from computer aided testing (CAT) data; and (3) performance ranking of subject data. It is demonstrated that interactive computer aided testing either by touch CRT's or personal computers is a useful research and training device for measuring pilot information management in diagnosing system failures in simulated flight situations. Performance is dictated by knowledge of aircraft sybsystems, initial pilot structuring of the failure symptoms and efficient testing of plausible causal hypotheses.

Limited surveys are available to assess the nutrition knowledge of children. The goals of this study were to test the validity and reliability of a computer nutrition knowledge survey for elementary school students and to evaluate the impact of the "Fit Kids 'r' Healthy Kids" nutrition intervention via the knowledge survey. During survey development, a sample (n=12) of health educators, elementary school teachers, and registered dietitians assessed the survey. The target population consisted of first- through fourth-grade students from Salt Lake City, UT, metropolitan area schools. Participants were divided into reliability (n=68), intervention (n=74), and control groups (n=59). The reliability group took the survey twice (2 weeks apart); the intervention and control groups also took the survey twice, but at pre- and post-intervention (4 weeks later). Only students from the intervention group participated in four weekly nutrition classes. Reliability was assessed by Pearson's correlation coefficients for knowledge scores. Results demonstrated appropriate content validity, as indicated by expert peer ratings. Test-retest reliability correlations were found to be significant for the overall survey (r=0.54; PNutrition knowledge was assessed upon program completion with paired samples t tests. Students from the intervention group demonstrated improvement in nutrition knowledge (12.2+/-1.9 to 13.5+/-1.6; Pnutrition survey demonstrated content validity and test-retest reliability for first- through fourth-grade elementary school children. Also, the study results imply that the Fit Kids 'r' Healthy Kids intervention promoted gains in nutrition knowledge.

Smith, P.

1997-03-01

This planning document outlines the steps necessary to develop, test, evaluate, and potentially implement a pilot chargeback system at the Idaho National Engineering and Environmental Laboratory for the treatment, storage, and disposal of current waste. This pilot program will demonstrate one system that can be used to charge onsite generators for the treatment and disposal of low-level radioactive waste. In FY 1997, mock billings will begin by July 15, 1997. Assuming approvals are received to do so, FY 1998 activities will include modifying the associated automated systems, testing and evaluating system performance, and estimating the amount generators will spend for waste storage, treatment, and disposal in FY 1999. If the program is fully implemented in FY 1999, generators will pay actual, automated bills for waste management services from funds transferred to their budgets from Environmental Management

The challenges of joint working: lessons from the Supporting People Health Pilot evaluation

Directory of Open Access Journals (Sweden)

Ailsa Cameron

2007-10-01

Full Text Available Purpose: This paper reports the findings of the evaluation of the Supporting People Health Pilots programme which was established to demonstrate the policy links between housing support services and health and social care services by encouraging the development of integrated services. The paper highlights the challenges of working across housing, health and social care boundaries. Method: The evaluation of the 6 health pilots rested on two main sources of data collection: Quarterly Project Evaluation Reports collected process data as well as reporting progress against aims and objectives. Semi-structured interviews - conducted across all key professional stakeholder groups and agencies and with people who used services - explored their experiences of these new services. Results: The ability of pilots to work across organisational boundaries to achieve their aims and objectives was associated not only with agencies sharing an understanding of the purpose of the joint venture, a history of joint working and clear and efficient governance arrangements but on two other characteristics: the extent and nature of statutory sector participation and, whether or not the service is defined by a history of voluntary sector involvement. In particular the pilots demonstrated how voluntary sector agencies appeared to be less constrained by organisational priorities and professional agenda and more able to respond flexibly to meet the complex needs of individuals. Conclusion and discussion: The pilots demonstrate that integrating services to support people with complex needs works best when the service is determined by the characteristics of those who use the service rather than pre-existing organisational structures.

Payne, Collin R.; Niculescu, Mihai; Just, David R.; Kelly, Michael P.

2015-01-01

Objectives We assessed the efficacy of an easy-to-implement shopper marketing nutrition intervention in a pilot and two additional studies to increase produce demand without decreasing store profitability or increasing shopper budgets. Methods We created grocery cart placards that detailed the number of produce items purchased (i.e., descriptive norm) at particular stores (i.e., provincial norm). The effect of these placards on produce spending was assessed across 971,706 individual person grocery store transactions aggregated by day. The pilot study designated a baseline period (in both control and intervention store) followed by installation of grocery cart placards (in the intervention store) for two weeks. The pilot study was conducted in Texas in 2012. In two additional stores, we designated baseline periods followed by 28 days of the same grocery cart placard intervention as in the pilot. Additional interventions were conducted in New Mexico in 2013. Results The pilot study resulted in a significant difference between average produce spending per day per person across treatment periods (i.e., intervention versus same time period in control) (16%) and the difference between average produce spending per day per person across stores in the control periods (4%); Furthermore, the same intervention in two additional stores resulted in significant produce spending increases of 12.4% and 7.5% per day per person respectively. In all stores, total spending did not change. Conclusions Descriptive and provincial social norm messages (i.e., on grocery cart placards) may be an overlooked tool to increase produce demand without decreasing store profitability and increasing shopper budgets.

Majamanda, J; Maureen, D; Munkhondia, T M; Carrier, J

2014-12-01

This systematic review aimed at examining the best available evidence on the effectiveness of community-based nutrition education in improving the nutrition status of under five children in developing countries. A systematic search of the literature was conducted utilising the following data bases: Cumulative Index to Nursing and Allied Health Literature (CINAHL), EMBASE, Medline, and Web of Knowledge. 9 studies were identified for the critical appraisal process. The Joanna Briggs Institute (JBI) critical appraisal check-list for experimental studies was utilised and two reviewers conducted the appraisal process independently. 7 studies were included for this review and data was extracted using the JBI data extraction form for experimental studies. The extracted data was heterogeneous as such narrative synthesis was conducted. The nutritional status of children in all studies improved and this was evidenced by increases in weight, height, mid upper arm circumference and reduced morbidity. Key messages about education were age at introduction of complementary foods, nutrition value on different types of feeds found locally and frequency of feeding the children. However, there were varied results regarding the effects of the intervention on the nutrition status of children. This was attributed by differences in implementers' characteristics, different intervention strategy and intensity, difference in age of the children at enrolment, pre-existing children's growth and nutritional status and follow-up periods. In addition to home visiting, conducting group meetings of care givers and community leaders, providing education twice a week and use of cooking demonstrations have shown that they produce highly significant findings. The evidence from the identified studies suggests that community- based nutrition education improves the nutrition status of under-five children in developing countries.

The purpose of this study was to examine the effect of a community-based nutrition education program on the nutritional knowledge, hemoglobin levels, and nutritional status of Nicaraguan adolescent girls and the nutritional knowledge of their mothers. Self-care deficit nursing theory was used in this study. This longitudinal study used a mixed quantitative/qualitative design to study the effect of the nutrition education program. The nonprobability sample consisted of 182 adolescent girls and 67 of their mothers. The setting for the study was a community (barrio) in Managua, Nicaragua. INTERVENTION/MEASUREMENT: A team of nurse and nutrition researchers created the nutrition education program designed to improve girls' and mother's nutrition-related self-care operations. Data collection was carried out for 4 years for girls and 2 years for mothers in Managua, Nicaragua, using questionnaires, a HemoCue, and anthropometric measures. The findings of this study were that girls' and mothers' nutritional knowledge scores significantly improved in most cases after participation in the nutrition intervention program. Girls' hemoglobin levels did not significantly improve and their nutritional status findings were mixed. Girls and mothers described what dietary changes girls made and why.

NUTRITIVE SUPPORT OF YOUNG SPORTSMEN USING A SPECIALIZED RUSSIAN PRODUCT

Full Text Available Organization of adequate nutrition of children and adolescents actively going in for sports is of the highest importance both for improving sports results and preserving children’s health. On the modern stage of sports neutraceuticals development, it is relevant to substantiate approaches to nutrition on all stages of the training process, develop methodological basis for individual nutrition selection and conduct demonstrative trials in order to evaluate efficacy of nutritional measures. The pediatric nutrition department of the FSBI “Scientific Center of Children’s Health” conducted a controlled trial of efficacy of a new Russian product for nutritive support of children in the training period in 2012 in order to study possibilities of nutrition optimization for young sportsmen. We noticed statistically significant alterations of bioimpedance analysis values – lean and active cell body mass – in the setting of nutrition correction – intake of 200-400 ml/day of the product for 21 days; at the same time, the fat mass remained the same. Psychological testing using WAN questionnaire (well-being, activity, mood conducted in the recovery period of the training process also revealed positive dynamics. The product may be used in the dose of 200-400 ml at any time of day; at the same time, it is most reasonable to take it as an additional food intake in the event of considerable training stress immediately before or after training, when adequate nutrition organization is hindered.

The effects of an individualised nutritional education and support programme on dietary habits, nutritional knowledge and nutritional status of 71 older adults living alone were examined. Although a regular dietary meal plan is recommended for improving nutritional status of older adults living alone, little research is done in this field in Korea. A pre- and post-test controlled quasi-experimental design was used at public health centres. The intervention group participated in an intensive nutritional education and support programme once a week for 8 weeks with dietary menus provided by home visiting nurses/dieticians; control group received usual care. Dietary habits and nutritional knowledge were assessed using structured questionnaires; nutritional intake status was analysed using Computer Aided Nutritional Analysis Program 5.0. The mean age of participants was 77.6 years, and 81.7% of the participants were women. At 8 weeks, there were significant interactions of group by time for dietary habits, nutritional knowledge and selected nutritional status of protein, iron and vitamins of B 2 and C. Changes over time in the mean score of dietary habits and nutritional knowledge were significantly improved in the intervention group compared to the control group. The percentages of normal nutrition intake of protein, iron and vitamins A and C in the intervention group were significantly higher than the control group at 8 weeks. Nutritional education and support programme positively impacted dietary habits, nutritional knowledge and selected nutritional status in older adults living alone, and we highlight the need for community-based nutritional education and counselling programmes. Older adults living alone in a community have relatively poor nutritional status and thus require tailored nutritional intervention according to objective nutritional analysis. It is necessary to link visiting nurses with dieticians in the community to manage effective nutritional

Roll paper pilot. [mathematical model for predicting pilot rating of aircraft in roll task

A mathematical model for predicting the pilot rating of an aircraft in a roll task is described. The model includes: (1) the lateral-directional aircraft equations of motion; (2) a stochastic gust model; (3) a pilot model with two free parameters; and (4) a pilot rating expression that is a function of rms roll angle and the pilot lead time constant. The pilot gain and lead time constant are selected to minimize the pilot rating expression. The pilot parameters are then adjusted to provide a 20% stability margin and the adjusted pilot parameters are used to compute a roll paper pilot rating of the aircraft/gust configuration. The roll paper pilot rating was computed for 25 aircraft/gust configurations. A range of actual ratings from 2 to 9 were encountered and the roll paper pilot ratings agree quite well with the actual ratings. In addition there is good correlation between predicted and measured rms roll angle.

2004-07-01

In view of the high prevalence of iron deficiency in preschool children and its consequences, this study was carried out to examine the effect of nutrition education and dietary modification on 438 two- to six-year-old nursery school children in Tehran in 1999. Sixty-two children who were judged anemic, iron-depleted, or having low iron stores were randomly allocated to "control," "dietary modification" (consuming one additional citrus fruit after lunch), and "nutrition education" (teaching the mothers proper eating patterns based on the food pyramid) groups. Food habits were surveyed, including 24-hour dietary recall and food frequency, as well as timing of consumption of special items; this survey was carried out for each child before and after intervention. After three months, blood samples were taken from the subjects. The prevalence of anemia, iron depletion, and low iron stores was 11.4, 62.8, and 15.1% respectively, with no significant differences observed in hemoglobin and percent transferrin saturation (%TS) between the groups. Mean+/-SD serum ferritin concentrations in "control," "diet modification," and "nutrition education" groups were 8.9+/-3.1, 9.5+/-3.7, and 6.9+/-2.3 microg/dL. The same figures at the end of intervention were 6.9+/-3.5, 11.2+/-5, and 10.7+/-5.9 microg/dL, respectively. Analysis of variance showed ferritin concentrations to be significantly different, in that there was a reduction in the control and elevation in the nutrition education groups. There was no significant difference in %TS before and after the intervention. During three months of intervention, changes in frequency of fruit and fruit juice intake after the meals in nutrition education and diet modification groups were significantly correlated to serum ferritin alteration. Frequency of fruit juice intake (rich in vitamin C) after meals (at least five times a week) can significantly increase serum ferritin within three months. Therefore, educating mothers of iron

To determine barriers to nutrition education, nutrition education resources used, and the relationship between nutrition knowledge and whether public school teachers in California teach nutrition in the classroom. A total of 102 teachers in California participated in a Web-based survey about nutrition education barriers, resources used to plan nutrition lessons, and factors that would encourage inclusion of nutrition. A validated questionnaire was used to assess nutrition knowledge. Analyses included ordinary least-squares regression. Common barriers were lack of instructional time and unrelated subject. Teachers were unaware of many nutrition education resources. Nutrition knowledge was not associated with nutrition lessons but was positively associated with teaching high school (β = 5.13; P Barriers of time and lack of unrelated subject matter are difficult to address but lack of awareness of resources indicates that promotion of existing resources may encourage teachers to provide nutrition education. Larger studies are needed to determine whether this holds true in a broader sample. Copyright © 2015 Society for Nutrition Education and Behavior. Published by Elsevier Inc. All rights reserved.

Pages with paragraphs on aging were identified in community nutrition and diet therapy textbooks, and 10% random samples of pages were evaluated in nutrition and aging textbooks. Paragraphs were assigned to one of four categories: gerontology, nutrition as primary, nutrition as secondary, or tertiary prevention. A total of 310 pages was qualitatively analyzed using NUD*IST 5 software and quantitatively with percentages. Only 7% of community nutrition and 2% of diet therapy pages were devoted to aging. There was little integration of aging beyond the chapters on aging. Community nutrition had the most gerontology (30%) and primary prevention (43%) content. Diet therapy and nutrition and aging had more secondary prevention (33% and 42%, respectively) and tertiary prevention (27% each) content. Some important databases and studies were absent. Of the 1,239 ageism words, 10% were positive, 53% neutral, and 36% negative. Photographs were generally positive. Women, but not minorities, reflected current older adult demographics. Future textbook editions should address aging more comprehensively and positively to better prepare dietitians for the job market. Recommendations for authors, course instructors, and publishers are given.

Given the scarcity of comprehensive nutritional data for Australia's >400 commercially produced seafood species a pilot study was undertaken to collect and analyse 22 species of wild and aquaculture seafood in order to develop a model for future comprehensive surveys. The species analysed were: Atlantic salmon, Australian sardine, prawn (six species), barramundi, abalone (three species), blue sprat, burrowing blackfish, gummy shark, oyster (four species), ocean trout and yellowtail kingfish. The analyses undertaken in this pilot study were: moisture, protein, total fat, cholesterol, fatty acids, vitamin C, vitamins A and D, and 21 mineral elements (including total mercury and methyl mercury). The data reported here are for vitamin D and mercury only. Comprehensive data have already been published elsewhere. Issues identified that should be addressed prior to undertaking a more extensive and representative study of the remaining major edible commercial Australian seafood species include: choice of samples and nutrients for analysis, facilities for sample handling and storage, data management and scrutiny, and laboratory quality control.

Traditional nutrition evaluations not only require the use of numerous tables and lists to provide sufficient recommendations for patients' diets but are also very time-consuming due to cross-referencing and calculations. To personalize patient assessments, this study implemented a Clinical Nutritional Information System (CNIS) to help hospital dietitians perform their daily work more effectively in terms of time management and paper work. The CNIS mainly targets in-patients who require cancer-nutrition counselling. The development of the CNIS occurred in three phases. Phase 1 included system design and implementation based on the Nutrition Care Process and Model (NCPM) and the Patient Nutrition Care Process. Phase 2 involved a survey to characterize the efficiency, quality and accuracy of the CNIS. In Phase 3, a second survey was conducted to determine how well dietitians had adapted to the system and the extent of improvement in efficiency after the CNIS had been available online for three years. The work time requirements decreased by approximately 58% with the assistance of the CNIS. Of the dietitians who used the CNIS, 95% reported satisfaction, with 91.66% indicating that the CNIS was really helpful in their work. However, some shortcomings were also evident according to the results. Dietitians favoured the standardization of nutritional intervention and monitoring. The CNIS meets the needs of dietitians by increasing the quality of nutritional interventions by providing accurate calculations and cross-referencing for information regarding patients' conditions, with the benefit of decreasing the processing time, such as handwritten documentation. In addition, the CNIS also helps dietitians statistically analyse each patient's personal nutritional needs to achieve nutritional improvement. Copyright © 2017 Elsevier B.V. All rights reserved.

Climate change further exacerbates the enormous existing burden of undernutrition. It affects food and nutrition security and undermines current efforts to reduce hunger and promote nutrition. Undernutrition in turn undermines climate resilience and the coping strategies of vulnerable populations. The objectives of this paper are to identify and undertake a cross-sectoral analysis of the impacts of climate change on nutrition security and the existing mechanisms, strategies, and policies to address them. A cross-sectoral analysis of the impacts of climate change on nutrition security and the mechanisms and policies to address them was guided by an analytical framework focused on the three 'underlying causes' of undernutrition: 1) household food access, 2) maternal and child care and feeding practices, 3) environmental health and health access. The analytical framework includes the interactions of the three underlying causes of undernutrition with climate change,vulnerability, adaptation and mitigation. Within broad efforts on climate change mitigation and adaptation and climate-resilient development, a combination of nutrition-sensitive adaptation and mitigation measures, climate-resilient and nutrition-sensitive agricultural development, social protection, improved maternal and child care and health, nutrition-sensitive risk reduction and management, community development measures, nutrition-smart investments, increased policy coherence, and institutional and cross-sectoral collaboration are proposed as a means to address the impacts of climate change to food and nutrition security. This paper proposes policy directions to address nutrition in the climate change agenda and recommendations for consideration by the UN Framework Convention on Climate Change (UNFCCC). Nutrition and health stakeholders need to be engaged in key climate change adaptation and mitigation initiatives, including science-based assessment by the Intergovernmental Panel on Climate Change (IPCC

In addition to providing specific sensory properties (e.g., flavor or textures), there is a need to produce foods that also provide functionality within the gastrointestinal (GI) tract, over and above simple nutrition. As such, there is a need to understand the physical and chemical processes occurring in the mouth, stomach, small intestine, and large intestine, in addition to the food structure-physiology interactions. In vivo techniques and in vitro models have allowed us to study and simulate these processes, which aids us in the design of food microstructures that can provide functionality within the human body. Furthermore, it is important to be aware of the health or nutritional needs of different groups of consumers when designing food structures, to provide targeted functionality. Examples of three groups of consumers (elderly, obese, and athletes) are given to demonstrate their differing nutritional requirements and the formulation engineering approaches that can be utilized to improve the health of these individuals. Eating is a pleasurable process, but foods of the future will be required to provide much more in terms of functionality for health and nutrition.

Optimal nutrition will be critical for crew members who embark on space exploration missions. Nutritional assessment provides an opportunity to ensure that crewmembers begin their missions in optimal nutritional status, to document changes during a mission and, if necessary, to provide intervention to maintain that status throughout the mission, and to assesses changes after landing in order to facilitate the return to their normal status as soon as possible after landing. We report here the findings from our nutritional assessment of astronauts who participated in the International Space Station (ISS) missions, along with flight and ground-based research findings. We also present ongoing and planned nutrition research activities. These studies provide evidence that bone loss, compromised vitamin status, and oxidative damage are the critical nutritional concerns for space travelers. Other nutrient issues exist, including concerns about the stability of nutrients in the food system, which are exposed to longterm storage and radiation during flight. Defining nutrient requirements, and being able to provide and maintain those nutrients on exploration missions, will be critical for maintaining crew member health.

Full Text Available Abstract Background Current guidelines for the provision of protein for critically ill patients are based on incomplete evidence, due to limited data from randomised controlled trials. The present pilot randomised controlled trial is part of a program of work to expand knowledge about the clinical effects of protein delivery to critically ill patients. The primary aim of this pilot study is to determine whether an enteral feeding protocol using a volume target, with additional protein supplementation, delivers a greater amount of protein and energy to mechanically ventilated critically ill patients than a standard nutrition protocol. The secondary aims are to evaluate the potential effects of this feeding strategy on muscle mass and other patient-centred outcomes. Methods This prospective, single-centred, pilot, randomised control trial will include 60 participants who are mechanically ventilated and can be enterally fed. Following informed consent, the participants receiving enteral nutrition in the intensive care unit (ICU will be allocated using a randomisation algorithm in a 1:1 ratio to the intervention (high-protein daily volume-based feeding protocol, providing 25 kcal/kg and 1.5 g/kg protein or standard care (hourly rate-based feeding protocol providing 25 kcal/kg and 1 g/kg protein. The co-primary outcomes are the average daily protein and energy delivered to the end of day 15 following randomisation. The secondary outcomes include change in quadriceps muscle layer thickness (QMLT from baseline (prior to randomisation to ICU discharge and other nutritional and patient-centred outcomes. Discussion This trial aims to examine whether a volume-based feeding protocol with supplemental protein increases protein and energy delivery. The potential effect of such increases on muscle mass loss will be explored. These outcomes will assist in formulating larger randomised control trials to assess mortality and morbidity.

Nutrition transition necessitates low and middle-income countries (LAMICs) to scale up their efforts in addressing the burdens of undernutrition and overweight/obesity. Magnitudes of undernutrition and overweight are high in LAMICs, but no study has reviewed the existence of nutrition policies to address it. No evidence is also available on the effect of nutrition policies and governance on the undernutrition and overweight/obesity patterns in such countries. We conducted a policy review to examine the presence and associations of nutrition policies and governance with the children's nutrition statuses in LAMICs. We reviewed nutrition policies, nutrition governance, and the trends of nutrition status from LAMICs. We retrieved data on the policies from the global database on the implementation of nutrition actions (GINA). We also retrieved data on the trends of nutrition status and nutrition governance from the nutrition landscape information system (NLiS), and on LAMICs from the World Bank database. We then analyzed the data both descriptively and by using a mixed effects model with random-intercept by country. Of the 139 LAMICs reviewed, only 39.6% had policies to address both undernutrition and overweight/obesity. A higher proportion of low-income countries (LICs) had policies to address undernutrition compared to that of middle-income countries (MICs) (86.1% vs. 63.1%, p = 0.002), and a low proportion of both had policy to address overweight. Having a nutrition policy that addresses undernutrition was not associated with better nutrition status outcomes. Strong nutrition governance in LAMICS was associated with low magnitudes of stunting (beta = -4.958, p = 0.015); wasting (beta = -5.418, p = 0.003); and underweight (beta = -6.452, p = 0.001). Despite high magnitudes of undernutrition and overweight/obesity in LAMICs, only about one third of them had nutrition policies to address such nutrition transition. Having strong nutrition governance may help to bring

Full Text Available Nutritional support of surgical patients is a necessary part of the treatment. It alone cannot cure the disease but it significantly affects the recovery of patients and supports surgical interventions. Patients in malnutrition have shown to have significantly more postoperative infectious and non-infectious complications. This significantly prolongs treatment time and increases costs. However, there is one fact that cannot be expressed in money, which is the patient's impression of the surgical intervention. Adequate preoperative patient support, based on the intake of liquid nutritive solutions, reduces preoperative stress and deflects the metabolic response. Now, it is recommended for adults and children older than one year to drink clear liquid up to 2 hours before induction in anesthesia. Appropriate enteral nutrition has a significant place in the postoperative recovery of patients. Enteral nutrition is reducing complications, mainly infectious complications because the function of the digestive system as one large immune system is preserved. Perioperative enteral nutrition is a necessary part of the modern treatment of surgical patients. In addition to the significant effect on the occurrence of postoperative complications, it is also important that this type of diet improves the psychological status of patients.

During spring 2015, teen ambassadors trained by Extension educators and volunteers at UC Elkus Ranch in San Mateo County taught nutrition science, food cultivation and healthy living skills in an 8-week, garden-based, after-school nutrition and physical education program for elementary school children in an urban setting. We conducted a pilot study using a mixed-methods approach to measure and explore the program's impact on children's vegetable selection and consumption preferences, as well as perceived self-efficacy in teen healthy living behavior. The children trended toward an increased preference for gardening, cooking and science, and teens displayed an increase in perceived health self-efficacy.

A prospective study of nutritional support during pelvic irradiation was carried out in 32 patients with a primary pelvic malignancy and prior weight loss. Both curative and palliative patients were eligible for the study. Seventeen patients were randomized to receive intravenous hyperalimentation (IVH) and fifteen patients served as controls who were maintained on their regular diet. Patients were stratified by percent body weight loss. Tolerance to therapy was assessed by evaluation of functional status and by using nutritional parameters of body weight change, change in serum protein levels, and response to delayed hypersensitivity skin tests. The curative IVH group tolerated therapy well by both functional and nutritional measurements. All curative IVH patients completed the planned radiation therapy without a treatment break and were fully active following treatment. Patients gained an average of 4.0 kg body weight during irradiation, which was significantly different from the curative control patients. They demonstrated a significant increase in serum transferrin reflecting an improvement in visceral protein. In addition, all showed a positive response to delayed hypersensitivity skin tests at the completion of irradiation. The palliative IVH patients often did poorly because of progression of disease and demonstrated only an elevation of serum transferrin during treatment. The results in the curative IVH group suggest a potential adjunctive role for intravenous hyperalimentation in the malnourished cancer patient undergoing pelvic irradiation. Clearly, further study of nutritional support during pelvic irradiation is needed using curative patients with a single tumor type and significant prior weight loss

Full Text Available Due to higher energy consumption, physically active people have higher nutritional requirements. In addition to other important factors for sports, such as good health and physical predisposition, adequate nutrition is a fundamental component. Sports nutrition must be well planned and individually adapted based on physical characteristics, tendencies towards gaining or losing weight, frequency, duration and intensity of training sessions. Studies have shown that a well-balanced ratio of macro and micronutrients, with the support of supplements and adequate hydration, can significantly improve athletic performance and plays a key role in achieving better results. An optimally designed nutritional program, with realistic and achievable goals, which complements a well-planned training program, is the basis for success in sports. Only when nutritional requirements are met, deficits can be prevented and performance in sport pushed to the limit.

Full Text Available Abstract Background Nutritional surveillance remains generally weak and early warning systems are needed in areas with high burden of acute under-nutrition. In order to enhance insight into nutritional surveillance, a community-based sentinel sites approach, known as the Listening Posts (LP Project, was piloted in Burkina Faso by Action Contre la Faim (ACF. This paper presents ACF’s experience with the LP approach and investigates potential selection and observational biases. Methods Six primary sampling units (PSUs were selected in each livelihood zone using the centric systematic area sampling methodology. In each PSU, 22 children aged between 6 and 24 months were selected by proximity sampling. The prevalence of GAM for each month from January 2011 to December 2013 was estimated using a Bayesian normal–normal conjugate analysis followed by PROBIT estimation. To validate the LP approach in detecting changes over time, the time trends of MUAC from LP and from five cross-sectional surveys were modelled using polynomial regression and compared by using a Wald test. The differences between prevalence estimates from the two data sources were used to assess selection and observational biases. Results The 95 % credible interval around GAM prevalence estimates using LP approach ranged between +6.5 %/−6.0 % on a prevalence of 36.1 % and +3.5 %/−2.9 % on a prevalence of 10.8 %. LP and cross-sectional surveys time trend models were well correlated (p = 0.6337. Although LP showed a slight but significant trend for GAM to decrease over time at a rate of −0.26 %/visit, the prevalence estimates from the two data sources showed good agreement over a 3-year period. Conclusions The LP methodology has proved to be valid in following trends of GAM prevalence for a period of 3 years without selection bias. However, a slight observational bias was observed, requiring a periodical reselection of the sentinel sites. This kind of surveillance

Enteral and Parenteral Nutrition in the Perioperative Period: State of the Art

Directory of Open Access Journals (Sweden)

Juan A. Sanchez

2013-02-01

Full Text Available Nutritional support of surgical and critically ill patients has undergone significant advances since 1936 when Studley demonstrated a direct relationship between pre-operative weight loss and operative mortality. The advent of total parenteral nutrition followed by the extraordinary progress in parenteral and enteral feedings, in addition to the increased knowledge of cellular biology and biochemistry, have allowed clinicians to treat malnutrition and improve surgical patient’s outcomes. We reviewed the literature for the current status of perioperative nutrition comparing parenteral nutrition with enteral nutrition. In a surgical patient with established malnutrition, nutritional support should begin at least 7–10 days prior to surgery. Those patients in whom eating is not anticipated beyond the first five days following surgery should receive the benefits of early enteral or parenteral feeding depending on whether the gut can be used. Compared to parenteral nutrition, enteral nutrition is associated with fewer complications, a decrease in the length of hospital stay, and a favorable cost-benefit analysis. In addition, many patients may benefit from newer enteral formulations such as Immunonutrition as well as disease-specific formulations.

Review of nutritional supplements for the treatment of bipolar depression.

Science.gov (United States)

Rakofsky, Jeffrey J; Dunlop, Boadie W

2014-05-01

Many patients view psychotropics with skepticism and fear and view nutritional supplements as more consistent with their values and beliefs. The purpose of this review was to critically evaluate the evidence base for nutritional supplements in the treatment of bipolar depression (BD). A literature search for all randomized, controlled clinical trials using nutritional supplements in the treatment of BD was conducted via PubMed and Ovid MEDLINE computerized database. The studies were organized into essential nutrients/minerals, nonessential nutrients, and combinations of nutritional products. Among essential nutrients/minerals, omega-3-fatty acids (O3FAs) have the strongest evidence of efficacy for bipolar depression, although some studies failed to find positive effects from O3FAs. Weak evidence supports efficacy of vitamin C whereas no data support the usefulness of folic acid and choline. Among nonessential nutrients, cytidine is the least supported treatment. Studies of N-acetylcysteine have not resolved its efficacy in treating acute depressive episodes relative to placebo. However, one study demonstrates its potential to improve depressive symptoms over time and the other, though nonsignificant, suggests it has a prophylactic effect. Studies of inositol have been mostly negative, except for 1 study. Those that were negative were underpowered but demonstrated numerically positive effects for inositol. There is no evidence that citicholine is efficacious for uncomplicated BD depression, though it may have value for comorbid substance abuse among BD patients. Finally, combination O3FA-cytidine lacks evidence of efficacy. The findings of this review do not support the routine use of nutritional supplements in the treatment or prophylaxis of BD depression. Studies with more rigorous designs are required before definitive conclusions can be made. Despite the inadequacy of the existing data, clinicians should remain open to the value of nutritional supplements: after

The symposium explored three different areas in the field where a more precise analysis of culture could enhance the effectiveness of nutrition science: 1) in the implementation of nutrition science research in the field; 2) in the collaboration of multiple stakeholders working to enhance nutrition in a national setting; and 3) in the language and discussions used to frame proposed changes in large scale food and nutrition security policy transnationally. Three social scientists, Monique Centrone Stefani, Lucy Jarosz, and David Pelletier were invited to share insights from their respective disciplines and respondents from within the field of nutrition provided initial reflections to better understand such perspectives. The symposium's interdisciplinary nature was designed to illustrate the challenge of multiple perspectives and methodologies and to advance understanding that could derive from such an exchange for those in the field of international nutrition seeking to decrease global hunger and malnutrition.

Early intervention with nutritional supplementation has been shown to halt malnutrition and may improve outcome in some patients with colorectal cancer. The aim of this study was to investigate whether dietary counseling, oral nutrition and megestrol acetate during chemotherapy affected nutritional status and survival in patients with advanced disease. Six hundred and twenty-eight patients with colorectal advanced disease were included in the study from January 2000 through December 2009 and divided into one of two groups. Group I consisted of 315 patients who were monitored prospectively and were given nutritional support. Group II included 313 patients without nutritional counseling and support. After the completion of chemotherapy all patients were evaluated (BMI, NST, Appetite Loss Scale and ECOG). After the completion of chemotherapy, there were lower proportions of patients in Group I with a BMI=5, loss of appetite and decreased weight gain. Nutritional counseling and supplemental feeding temporarily halted weight loss and improved appetite. This improvement may have implications for patient survival. Patients with early nutritional support lived 19.1 months while patients in the control group had a survival of 12.4 months (p=0.022). This study demonstrated that concurrent individualized dietary counseling and nutritional support are effective in improving nutritional status thereby lessening chemotherapy-induced morbidity.

Cancer and its treatment result in severe biochemical and physiological alterations associated with a deterioration of quality of life (QoL). Cancer-related malnutrition may evolve into cancer cachexia due to complex interactions between pro-inflammatory cytokines and the host metabolism. Depending on the type of cancer treatment (either curative or palliative), the clinical condition of the patient and nutritional status, adequate and patient-tailored nutritional intervention should be prescribed (diet counseling, oral supplementation, enteral or total parenteral nutrition). Nutritional support has been widely advocated as adjunctive therapy for a variety of underlying illnesses, including surgery and medical oncotherapy (radiation or chemotherapy for cancer). Glutamine, n-3 fatty acids and probiotics/prebiotics are therapeutic factors that potentially modulate gastrointestinal toxicity related to cancer treatments. Enteral and parenteral nutrition may help improve patient survival, functional status and QoL, yet the benefits appear to be primarily limited to patients with good functional status and with gastrointestinal disease affecting nutritional intake. Parenteral nutrition offers the possibility of increased or maintenance of the nutrient intake in patients for whom normal food intake is inadequate and for whom enteral nutrition is not feasible, is contraindicated or is not accepted by the patient. This article reviews evidence on issues relevant to enteral and parenteral nutrition in patients with cancer.

International cooperation for food and nutrition security: Systematization of the participatory, contextualized, and intersectoral educational practices

Full Text Available ABSTRACT The present study systematized the experience gained with the project Construindo capacidades em segurança alimentar e nutricional no Brasil, Canadá e Angola (2004-2010, Building food and nutrition security skills in Brazil, Canada, and Angola, whose objective was to qualify actions that promote food and nutrition security in the three countries using different educational practices. The activities were organized in the following subprojects: (a online distance learning courses; (b workshops to train managers, government technicians, representatives of civil society organizations, and social subjects who offered to act as a link between communities; and (c local pilot projects. The present study reports this experience. The educational practices implemented in the municipalities of Araçuaí (MG, Juazeiro (BA, and Fortaleza (CE were analyzed based on systematized information in the project reports and activity records (texts and photographs. The analytical reference was based on the concept of food and nutrition education, guided by the fundamentals of Popular Education and Paulo Freire; on the concept of food and nutrition security; and on the following analytical dimensions: participation, contextualization of educational practices, and intersectoriality. The results evidenced how educational practices contributed to the construction of shared concepts of food and nutrition security from an intersectoral and participatory perspective that values the peculiarities of diet in different socioeconomic and cultural contexts, and highlights daily situations and local traditions. They also expose the limits and potentialities of an experience of this magnitude, conducted from an interdisciplinarity perspective and using participatory methods.

The Alberta Pregnancy Outcomes and Nutrition (APrON) study is an ongoing prospective cohort study that recruits pregnant women early in pregnancy and, as of 2012, is following up their infants to 3 years of age. It has currently enrolled approximately 5000 Canadians (2000 pregnant women, their offspring and many of their partners). The primary aims of the APrON study were to determine the relationships between maternal nutrient intake and status, before, during and after gestation, and (1) maternal mood; (2) birth and obstetric outcomes; and (3) infant neurodevelopment. We have collected comprehensive maternal nutrition, anthropometric, biological and mental health data at multiple points in the pregnancy and the post-partum period, as well as obstetrical, birth, health and neurodevelopmental outcomes of these pregnancies. The study continues to follow the infants through to 36 months of age. The current report describes the study design and methods, and findings of some pilot work. The APrON study is a significant resource with opportunities for collaboration. © 2012 John Wiley & Sons Ltd.

The relationship between mother's nutritional knowledge, maternal education, and child nutritional status (weight-for-age) was the subject of investigation in this study. The data were collected in Ghana on 55 well nourished and 55 malnourished mother-child pairs. A questionnaire designed to collect data on mother's knowledge and practices related to child care and nutrition was administered to the mothers. Data on mother's demographic and socio-economic characteristics as well as child anthropometric data were also collected. A nutrition knowledge score was calculated based on mother's responses to the nutrition related items. Bivariate analysis gave significant associations between child nutritional status and the following variables: time of initiating of breastfeeding, mother's knowledge of importance of colostrum and whether colostrum was given to child, age of introduction of supplementary food, and mother's knowledge about causes of kwashiorkor. The two groups also showed significant differences in their nutrition knowledge scores. Maternal formal education, and marital status were also found to be associated with child nutritional status in bivariate analyses. Further analysis with logistic regression revealed that maternal nutrition knowledge was independently associated with nutritional status after the effects of other significant variables were controlled for. Maternal education on the other hand was not found to be independently associated with nutritional status. These results imply that mother's practical knowledge about nutrition may be more important than formal maternal education for child nutrition outcome.

This study examined the association between mean age of pilot, pilot license, pilot medical certificate and drug use trends in pilots fatally injured in aircraft accidents. The prevalence of prescription drugs, OTC drugs, controlled drugs and drugs that may be potentially impairing was also examined. This study was a descriptive observational study in which the NTSB Aviation Accident Database was searched from the period beginning January 1, 2012 to December 31, 2014. During the study period a total of 706 accidents involving 711 fatalities were investigated by the NTSB. This study included 633 of these accidents, involving 646 fatalities. Of these pilots, 42.1% had drugs in their biological samples. The prevalence of prescription drugs, controlled drugs, OTC drugs, opioids, and potentially impairing drugs in the fatally injured pilot population over the study period was 28.9%, 15.0%, 20.1%, 5.1%, and 25.5%, respectively. Pilots with any drugs in their samples were significantly older than those without drugs. Medical certificate held was associated with drug use; pilots who held third class certificates had the highest prevalence at 54.1%. Pilot license was not associated with drug use. In 3.8% of the accidents, drugs were a contributing factor in the cause. Despite current FAA medical regulations, potentially impairing drugs are frequently found in biological samples of fatally injured pilots in the U.S. More education of airmen by aviation medical examiners is needed on the safety of drug use.Akparibo IY, Stolfi A.

There is a new merging of health economics and nutrition disciplines to assess the impact of diet on health and disease prevention and to characterise the health and economic aspects of specific changes in nutritional behaviour and nutrition recommendations. A rationale exists for developing the field of nutrition economics which could offer a better understanding of both nutrition, in the context of having a significant influence on health outcomes, and economics, in order to estimate the absolute and relative monetary impact of health measures. For this purpose, an expert meeting assessed questions aimed at clarifying the scope and identifying the key issues that should be taken into consideration in developing nutrition economics as a discipline that could potentially address important questions. We propose a first multidisciplinary outline for understanding the principles and particular characteristics of this emerging field. We summarise here the concepts and the observations of workshop participants and propose a basic setting for nutrition economics and health outcomes research as a novel discipline to support nutrition, health economics and health policy development in an evidence and health-benefit-based manner.

The efficacy of enteral nutrition in postoperative nutritional management is known, but the effects on gastrointestinal motility and nutrition have not yet been elucidated. The purpose of this study was to compare the effects of enteral and parenteral nutrition soon after open abdominal surgery on gastrointestinal motility and nutritional status. A partial resection of rectum models was prepared to compare two types of nutrient administration: enteral nutrition and total parenteral nutrition. The differences between the effects of nutrition types in terms of gastrointestinal motility and nutritional status were investigated. Enteral nutrition contributed to recovery of gastrointestinal motility and maintenance of nutritional status. Enteral nutrition should therefore be initiated soon after surgery if the gastrointestinal tract is available.

Full text: • Objective: Malnutrition is a persistent problem in the Philippines. The 2011 survey of the Food and Nutrition Research Institute reported that 3 out of 10 children are malnourished. Data shows 20.2% of children 0-47 months are underweight while 33.6% are stunted. This rate is higher in depressed areas in the country. PD Hearth is a time and tested effective program model to address malnutrition. But the PDH has minimum standards that need to be followed in the program implementation. However, a developing country like the Philippines has limitations in its resources and implementations. This paper aims to share the Philippine experience in addressing moderate malnutrition through a contextualized and modified PD Hearth approach. The specific objectives of this paper are: - to describe the challenges in implementing PD Hearth in the context of the Philippines; - to describe the innovations and modifications in the PD Hearth; - and, to illustrate the successful intervention of the PNH program against malnourished children in the community. • Methods: The Pinoy Nutrition Hub model is an innovation of PD Hearth approach. The first step was the participatory approach evaluation of existing programs on MNCHN in the communities. The next step was for the stakeholders to identify the gaps and address them. This was followed by gathering lessons learned and good practices that arose from implementing PD Hearth. Innovations were adopted to address restrictions and maximize learning in its implementation. The contextualized approach was called Pinoy Nutrition Hub (PNH). • Outcomes: - The PNH was piloted in three Area Development Programs (ADP) that represent the three island groups of the Philippines. All three ADPs reported improvement in the weight of the malnourished children enrolled in the program. Below is an illustration of the how the actual weight of children in the Visayas ADP increased.

Full Text Available Conducting research in the area of sexual violence has complex ethical and practical challenges for the researcher. Managing ethical issues in sexual violence is important and can be achieved through the use of pilot studies. The primary purpose of the pilot study was to identify and manage potential ethical and practical problems that could jeopardise the main study or violate the ethical and human rights of participants in the main study on women’s journey of recovery from sexual assault. The secondary purpose was to collect preliminary data in order to determine the human, financial and time resources needed for a planned study. The methods and processes used in conducting the pilot study in the study on women’s journey of recovery are discussed according to each of the objectives of the pilot study, methods used to achieve the objective, observations or findings made during the pilot study, and implications for the main study. This article aims to demonstrate how a pilot study was used to manage identified potential ethical and practical research issues during the recruitment of participants and data collection for the research that was conducted by the first author to investigate women’s journey of recovery from sexual assault trauma within the first week following sexual assault.

Optimal strategies to improve food security and nutrition for people living with HIV (PLHIV) may differ in settings where overweight and obesity are prevalent and cardiovascular disease risk is a concern. However, no studies among PLHIV have investigated the impact of food support on nutritional outcomes in these settings. We therefore assessed the effect of food support on food insecurity and body weight in a population of PLHIV with high prevalence of overweight and obesity. We implemented a pilot intervention trial in four government-run HIV clinics in Honduras. The trial tested the effect of a monthly household food ration plus nutrition education (n = 203), compared to nutrition education alone (n = 197), over 12 months. Participants were clinic patients receiving antiretroviral therapy (ART). Assessments were obtained at baseline, 6 and 12 months. Primary outcomes for this analysis were food security, using the validated Latin American and Caribbean Food Security Scale and body weight (kg). Thirty-one percent of participants were overweight (22%) or obese (8%) at baseline. At 6 months, the probability of severe food insecurity decreased by 48.3% (p < 0.01) in the food support group, compared to 11.6% in the education-only group (p < 0.01). Among overweight or obese participants, food support led to average weight gain of 1.13 kg (p < 0.01), while nutrition education alone was associated with average weight loss of 0.72 kg (p < 0.10). Nutrition education alone was associated with weight gain among underweight and normal weight participants. Household food support may improve food security but not necessarily nutritional status of ART recipients above and beyond nutrition education. Improving nutritional tailoring of food support and testing the impact of nutrition education should be prioritized for PLHIV in Latin America and similar settings.

Position of the Academy of Nutrition and Dietetics: oral health and nutrition.

It is the position of the Academy of Nutrition and Dietetics that nutrition is an integral component of oral health. The Academy supports integration of oral health with nutrition services, education, and research. Collaboration between dietetics practitioners and oral health care professionals is recommended for oral health promotion and disease prevention and intervention. Scientific and epidemiological data suggest a lifelong synergy between diet, nutrition, and integrity of the oral cavity in health and disease. Oral health and nutrition have a multifaceted relationship. Oral infectious diseases, as well as acute, chronic, and systemic diseases with oral manifestations, impact an individual's functional ability to eat and their nutrition status. Likewise, nutrition and diet can affect the development and integrity of the oral cavity and progression of oral diseases. As knowledge of the link between oral and nutrition health increases, dietetics practitioners and oral health care professionals must learn to provide screening, education, and referrals as part of comprehensive client/patient care. The provision of medical nutrition therapy, including oral and overall health, is incorporated into the Standards of Practice for registered dietitians and dietetic technicians, registered. Inclusion of didactic and clinical practice concepts that illustrate the role of nutrition in oral health is essential in education programs for both professional groups. Collaborative endeavors between dietetics, dentistry, medicine, and allied health professionals in research, education, and delineation of practice roles are needed to ensure comprehensive health care. The multifaceted interactions between diet, nutrition, and oral health in practice, education, and research in both dietetics and dentistry merit continued, detailed delineation.

Optimal nutrition is essential for general well being, maintenance of physical and functional capacities and prevention of chronic disease in the elderly. The 5-year longitudinal study, NuAge, was designed to assess the pivotal role of nutrition on physical and cognitive status, functional autonomy and social functioning. A cohort of 1793 men and women, selected from three age groups (68-72, 73-77, 78-82) at recruitment, has been followed annually since 2003-2004. A plurimethodological approach, including basic, clinical, epidemiologic, and social research has been used. Data on various facets of nutritional status (diet, food habits, appetite, anthropometry and body composition), and functional (muscle strength, physical activity, physical and functional capacities and performance), medical (physical, mental and cognitive health, medication) and social data (network, support, participation) are collected by questionnaires or direct measurements. Blood, urine, and saliva samples are also collected and processed for genomic, transcriptomic, proteomic, and biochemical analyses and to study markers of endocrine, immune, and cognitive functions. Selected bio-psycho-social characteristics of the cohort, consumption of macronutrients, and biologic variables are presented, including the impact of intake of certain foods on total antioxidant status. Understanding the aging process as regulated by a modifiable factor such as nutrition should facilitate the development of targeted strategies for promoting successful aging.

Modular Enteral Nutrition may be a substitute for Parenteral Nutrition in children with different pathologies. Study of 4 children with different pathologies selected from a group of 40 admitted to the Maternal-Childrens Hospital "Valle de Hebrón" in Barcelona, who received modular enteral nutrition. They were monitored on a daily basis by the Dietician Service. Modular enteral nutrition consists of modules of proteins, peptides, lipids, glucids and mineral salts-vitamins. 1.--Craneo-encephalic traumatisms with loss of consciousness, Feeding with a combination of parenteral nutrition and modular enteral nutrition for 7 days. In view of the tolerance and good results of the modular enteral nutrition, the parenteral nutrition was suspended and modular enteral nutrition alone used up to a total of 43 days. 2.--55% burns with 36 days of hyperproteic modular enteral nutrition together with normal feeding. A more rapid recovery was achieved with an increase in total proteins and albumin. 3.--Persistent diarrhoea with 31 days of modular enteral nutrition, 5 days on parenteral nutrition alone and 8 days on combined parenteral nutrition and modular enteral nutrition. In view of the tolerance and good results of the modular enteral nutrition, the parenteral nutrition was suspended. 4.--Mucoviscidosis with a total of 19 days on modular enteral nutrition, 12 of which were exclusively on modular enteral nutrition and 7 as a night supplement to normal feeding. We administered proteic intakes of up to 20% of the total calorific intake and in concentrations of up to 1.2 calories/ml of the final preparation, always with a good tolerance. Modular enteral nutrition can and should be used as a substitute for parenteral nutrition in children with different pathologies, thus preventing the complications inherent in parenteral nutrition.

Nutritional surveillance.

Science.gov (United States)

Mason, J B; Mitchell, J T

1983-01-01

The concept of nutritional surveillance is derived from disease surveillance, and means "to watch over nutrition, in order to make decisions that lead to improvements in nutrition in populations". Three distinct objectives have been defined for surveillance systems, primarily in relation to problems of malnutrition in developing countries: to aid long-term planning in health and development; to provide input for programme management and evaluation; and to give timely warning of the need for intervention to prevent critical deteriorations in food consumption. Decisions affecting nutrition are made at various administrative levels, and the uses of different types of nutritional surveillance information can be related to national policies, development programmes, public health and nutrition programmes, and timely warning and intervention programmes. The information should answer specific questions, for example concerning the nutritional status and trends of particular population groups.Defining the uses and users of the information is the first essential step in designing a system; this is illustrated with reference to agricultural and rural development planning, the health sector, and nutrition and social welfare programmes. The most usual data outputs are nutritional outcome indicators (e.g., prevalence of malnutrition among preschool children), disaggregated by descriptive or classifying variables, of which the commonest is simply administrative area. Often, additional "status" indicators, such as quality of housing or water supply, are presented at the same time. On the other hand, timely warning requires earlier indicators of the possibility of nutritional deterioration, and agricultural indicators are often the most appropriate.DATA COME FROM TWO MAIN TYPES OF SOURCE: administrative (e.g., clinics and schools) and household sample surveys. Each source has its own advantages and disadvantages: for example, administrative data often already exist, and can be

Demonstration of reliability centered maintenance

International Nuclear Information System (INIS)

Schwan, C.A.; Morgan, T.A.

1991-04-01

Reliability centered maintenance (RCM) is an approach to preventive maintenance planning and evaluation that has been used successfully by other industries, most notably the airlines and military. Now EPRI is demonstrating RCM in the commercial nuclear power industry. Just completed are large-scale, two-year demonstrations at Rochester Gas ampersand Electric (Ginna Nuclear Power Station) and Southern California Edison (San Onofre Nuclear Generating Station). Both demonstrations were begun in the spring of 1988. At each plant, RCM was performed on 12 to 21 major systems. Both demonstrations determined that RCM is an appropriate means to optimize a PM program and improve nuclear plant preventive maintenance on a large scale. Such favorable results had been suggested by three earlier EPRI pilot studies at Florida Power ampersand Light, Duke Power, and Southern California Edison. EPRI selected the Ginna and San Onofre sites because, together, they represent a broad range of utility and plant size, plant organization, plant age, and histories of availability and reliability. Significant steps in each demonstration included: selecting and prioritizing plant systems for RCM evaluation; performing the RCM evaluation steps on selected systems; evaluating the RCM recommendations by a multi-disciplinary task force; implementing the RCM recommendations; establishing a system to track and verify the RCM benefits; and establishing procedures to update the RCM bases and recommendations with time (a living program). 7 refs., 1 tab

Obesity as a form of malnutrition: over-nutrition on the Uganda "malnutrition" agenda.

Science.gov (United States)

Ngaruiya, Christine; Hayward, Alison; Post, Lori; Mowafi, Hani

2017-01-01

The objectives were to highlight the burden of overweight and obesity as an additional area of importance for the malnutrition agenda in Uganda and to provide evidence-based considerations for stakeholders involved. Mirroring other Low- and Middle-Income Countries (LMICs), Uganda is experiencing a "double burden" of over-nutrition related issues - both obesity and overweight, and related non-communicable diseases (NCDs) alongside the under-nutrition that has long plagued the country. Despite the commonplace assumption that under-nutrition is the predominant form of malnutrition in Uganda, we explore recent literature that in fact, challenges this notion. While food insecurity has contributed to the under-nutrition problem, a lack of dietary diversity also has a demonstrated role in increasing over-nutrition. We cannot afford to ignore over-nutrition concomitant with stunting and wasting in the country. Increase in the burden of this less acknowledged form of malnutrition in Uganda is critical to investigate, and yet poorly understood. A move towards increased regionally targeted over-nutrition research, funding, government prioritization and advocacy is needed.

The role of diet and nutrition on mental health and wellbeing.

Science.gov (United States)

Owen, Lauren; Corfe, Bernard

2017-11-01

Mental, neurological and substance-use disorders presently represent the greatest global burden of disease. Likewise, depression and other psychopathologies are elevated risk comorbidities of other health hazards, such as obesity. Nutrition has been implicated in behaviour, mood and in the pathology and treatment of mental illness. In this brief editorial, we aim to set the scale of the problem in context and overview advances and recent evidence linking nutrition to psychological outcomes. The purpose of the 2016 Nutrition Society Winter Meeting, 'Diet, nutrition and mental health and wellbeing' was to review where the evidence is strong, where there are unmet needs for research and to draw together the communities working in this area to share their findings. The papers presented demonstrated clear advancements that are being made in this field. The meeting illustrated compelling support for nutrition as a modifiable risk factor. The present research in the field and evidence presented at the 2016 Nutrition Society Winter Meeting lead us to postulate that even interventions with relatively modest effect sizes may plausibly and significantly curtail the disease burden of mental and neurological disease by food- and nutrient-based approaches.

BACKGROUND: Malnutrition is frequent among patients with malignancies and associated with impaired function, reduced quality of life and increased mortality. Few data are available in patients with neuroendocrine tumors (NET) on nutritional status, nutritional risk, and nutrition impact symptoms...... (NIS). We aimed to assess nutritional status (NS) and risk, level of function and associations with NIS in NET patients. METHODS: In a cross-sectional study of NET patients, we measured body mass index (BMI) and handgrip strength (HGS) as markers of NS and muscle function assessed by HGS....... The nutritional risk score (NRS) was determined by NRS-2002. NIS was assessed by the eating symptoms questionnaire (ESQ), and disease-related appetite questionnaire (DRAQ). RESULTS: We included 186 patients (51% women), median age 66 years. We observed low BMI (

An immigrant Hispanic population in the Texas-Mexico border region urgently requested assistance with diabetes. The project team implemented an exploratory pilot intervention to prevent type 2 diabetes in the general population through enhanced nutrition and physical activity. Social networks in low-income rural areas(colonias) participated in an adaptation of the Diabetes Empowerment Education Program. The program had a pre-post-test design with a comparison group. The intervention had a small but significant effect in lowering body mass index, the biological outcome variable. The process evaluation shows that the participants valued the pilot project and found it culturally and economically appropriate. This program was the first primary prevention program in diabetes to address a general population successfully. The study shows that low-income, rural Mexican American families will take ownership of a program that is participatory and tailored to their culture and economic situation.

The Manufacturing Demonstration Facility (MDF) low temperature materials synthesis project was established to demonstrate a scalable and sustainable process to produce nanoparticles (NPs) for advanced manufacturing. Previous methods to chemically synthesize NPs typically required expensive, high-purity inorganic chemical reagents, organic solvents and high temperatures. These processes were typically applied at small laboratory scales at yields sufficient for NP characterization, but insufficient to support roll-to-roll processing efforts or device fabrication. The new NanoFermentation processes described here operated at a low temperature (~60 C) in low-cost, aqueous media using bacteria that produce extracellular NPs with controlled size and elemental stoichiometry. Up-scaling activities successfully demonstrated high NP yields and quality in a 900-L pilot-scale reactor, establishing this NanoFermentation process as a competitive biomanufacturing strategy to produce NPs for advanced manufacturing of power electronics, solid-state lighting and sensors.

Protein-based sports supplements are among the more common types of nutrition supplements consumed by athletes; however, there is currently limited data investigating the knowledge, motivations and occurrence of use among the adolescent population (13-18 years). This pilot study looks to obtain initial data regarding the use of protein supplements in this population. This study investigates the understanding and occurrence of protein supplement use in 87 adolescent athletes based in an Australian capital city who compete in a variety of sports. Sources of information, regularity of use, purchasing habits, associated risk knowledge and supplement beliefs were examined using a self-reported, written questionnaire. A total of 60% (n = 52) of athletes reported using protein supplements, with a positive relationship between age and use (P supplement consumption, with the most common risk reported as 'I don't know' (22%). Coaches were found to initiate protein supplement use more than other figures in the athlete's life (50%) and were the primary source of information regarding supplements (58%). It was found that 19% of adolescent athletes obtained information about protein supplements from the Internet, and 17% of all consumers purchase their supplements online. The evident lack of knowledge regarding protein supplements demonstrates a necessity for further education of athletes, coaches and families regarding the responsible purchasing and use of protein supplements in the current landscape of sports nutrition. Future research should further explore the role of the Internet in protein supplement purchase and education. © 2017 Dietitians Association of Australia.

Integrated carbon-to-liquids technology (ICTL) incorporates three basic processes for the conversion of a wide range of feedstocks to distillate liquid fuels: (1) Direct Microcatalytic Coal Liquefaction (MCL) is coupled with biomass liquefaction via (2) Catalytic Hydrodeoxygenation and Isomerization (CHI) of fatty acid methyl esters (FAME) or trigylceride fatty acids (TGFA) to produce liquid fuels, with process derived (3) CO₂ Capture and Utilization (CCU) via algae production and use in BioFertilizer for added terrestrial sequestration of CO₂, or as a feedstock for MCL and/or CHI. This novel approach enables synthetic fuels production while simultaneously meeting EISA 2007 Section 526 targets, minimizing land use and water consumption, and providing cost competitive fuels at current day petroleum prices. ICTL was demonstrated with Montana Crow sub-bituminous coal in MCL pilot scale operations at the Energy and Environmental Research Center at the University of North Dakota (EERC), with related pilot scale CHI studies conducted at the University of Pittsburgh Applied Research Center (PARC). Coal-Biomass to Liquid (CBTL) Fuel samples were evaluated at the US Air Force Research Labs (AFRL) in Dayton and greenhouse tests of algae based BioFertilizer conducted at Montana State University (MSU). Econometric modeling studies were also conducted on the use of algae based BioFertilizer in a wheat-camelina crop rotation cycle. We find that the combined operation is not only able to help boost crop yields, but also to provide added crop yields and associated profits from TGFA (from crop production) for use an ICTL plant feedstock. This program demonstrated the overall viability of ICTL in pilot scale operations. Related work on the Life Cycle Assessment (LCA) of a Montana project indicated that CCU could be employed very effectively to reduce the overall carbon footprint of the MCL/CHI process. Plans are currently being made to conduct larger

Malnutrition is a common medical problem in cancer patients with a negative impact on quality of life. The aim of this study was to address different issues related to nutritional management of cancer patients in clinical practice. A multidisciplinary group of experts in Medical Oncology, Pharmacy, and Endocrinology and Nutrition prepared a list of topics related to the nutritional status of cancer patients and grouped them into three blocks: nutritional support, parenteral nutrition (PN), and home PN (HPN). A literature review was made of articles published in Spanish, English and French until April 2017. This consensus emphasizes several key elements that help physicians standardize management of the nutritional status of cancer patients in clinical practice, and establishes common guidelines for indication, monitoring, nutritional requirements, and access routes to PN.

1984-01-01

The control rod drive system in a Boiling Water Reactor is the most important safety system in the power plant. All components of the system can be verified except the solenoid operated, scram pilot valves without scramming a rod. The pilot valve mechancial works is the weak link to the control rod drive system. These pilot valves control the hydraulic system which applies pressure to the ''insert'' side of the control rod piston and vents the ''withdraw'' side of the piston causing the rods to insert during a scam. The only verification that the valve is operating properly is to scram the rod. The concern for this portion of the system is demonstrated by the high number of redundant components and complete periodic testing of the electrical circuits. The pilot valve can become hung-up through wear, fracture of internal components, mechanical binding, foreign material or chemicals left in the valve during maintenance, etc. If the valve becomes hung-up the electrical tests performed will not indicate this condition and scramming the rod is in jeopardy. Only an attempt to scram a rod will indicate the hung-up valve. While this condition exists the rod is considered inoperative. This paper describes a system developed at a nuclear power plant that monitors the pilot valves on the control rod drive system. This system utilizes pattern recognition to assure proper internal workings of the scram pilot valves to plant operators. The system is totally automatic such that each time the valve is operated on a ''half scram'', a printout is available to the operator along with light indication that each of the 370 valves (on one unit of a BWR) is operating properly. With this monitoring system installed, all components of the control rod drive system including the solenoid pilot valves can be verified as operational without scramming any rods

Full Text Available Introduction: This study was conducted to assess the nutritional status in Iranian major depres-sive disorder patients. We also determined the relationship between nutrients intake with depres-sion severity.Methods: Seventy major depressive patients were selected randomly from outpatient depressive subjects, referred to Razi Psychiatry Hospital in Tabriz, Iran in 2007. Dietary intakes were rec-orded and compared with dietary reference intakes (DRIs. Definition of the disease and its se-verity were according to DSM-IV-TR and Hamilton Depression Rating Scale, respectively. Nu-tritionist III program, Chi-square, correlation and t-test were used for data analyses. Demo-graphic, clinical and laboratory data were analyzed using SPSS software for windows (ver-sion13.0.Results: According to dietary analysis, 11.4% and 55% of patients had dietary protein and energy deficiency, respectively. 97.1% and 95.7% of patients had less folate and B12 intakes than recom-mended dietary allowances. The mean (Mean ± SD for plasma folate and B12 was 5.18±6.11 ng/ml and 389.05±346.9 pg/ml, respectively. Low plasma folate and B12 was observed in 51.4% and 50.0 % of patients, respectively. There was no significant relationship between blood folate and B12 levels with depression severity. Similarly, nutrients intake had no effect on depression se-verity.Conclusions: Low plasma concentrations and low dietary intakes of folate and B12 are common among Tabrizian depressive patients. It seems that nutritional intervention for increasing folate and vitamin B12 intake must be considered as health promotive and preventative program for pa-tients suffering from depression disorders.

There has been an increase in the knowledge and interest on nutrition, and functional foods have gained popularity over the last few decades, and the trend is increasing. Probiotics and prebiotics are among the most studied functional foods. Nutrition economics has been defined as the discipline dedicated to researching and characterising health and economic outcomes in nutrition for the benefit of society. The concept and its application to probiotics and prebiotics will be discussed in terms of health and economic benefits and their evaluation. Health economics and concrete applications showing how to maximise long-term nutritional benefits will contribute to motivate consumers in making food choices based on a rational understanding of their own interest. We present a model that shows that nutrition economics can be used as an analytical tool for product and service network development.

Patients dependent on parenteral nutrition (PN) are among a group at risk of developing iodine deficiency. Supplementation with iodine in this population has been debated in a number of studies, resulting in variable clinical practices. The Committee on Clinical Practice Issues of the American Society for Clinical Nutrition recommends a dose of 1 mcg/kg/d of parenteral iodine for patients receiving PN. At our institution, PN trace elements do not include iodine, although this is not the case internationally. Our study sought to assess iodine levels and thyroid function in a cohort of PN-dependent pediatric patients. A retrospective analysis studied 32 pediatric patients with a variety of medical diagnoses who received PN as a primary means of nutrition for 6 months or longer. Patients received variable proportions of their total caloric intake as PN, which ranged from 14%-100%. Iodine and thyroid function levels were obtained by serum sampling. No patient in our cohort of 32 demonstrated thyroid dysfunction or developed iodine deficiency. The length of time on PN and the percentage of total nutrition intake as PN were not associated with iodine levels (P Parenteral and Enteral Nutrition.

A beginner's guide to nutritional profiling in physiology and ecology.

The nutritional history of an organism is often difficult to ascertain. Nonetheless, this information on past diet can be particularly important when explaining the role of nutrition in physiological responses and ecological dynamics. One approach to infer the past dietary history of an individual is through characterization of its nutritional phenotype, an interrelated set of molecular and physiological properties that are sensitive to dietary stress. Comparisons of nutritional phenotypes between a study organism and reference phenotypes have the potential to provide insight into the type and intensity of past dietary constraints. Here, we describe this process of nutritional profiling for ecophysiological research in which a suite of molecular and physiological responses are cataloged for animals experiencing known types and intensities of dietary stress and are quantitatively compared with those of unknown individuals. We supplement this delineation of the process of nutritional profiling with a first-order analysis of its sensitivity to the number of response variables in the reference database, their responsiveness to diet, and the size of reference populations. In doing so, we demonstrate the considerable promise this approach has to transform future studies of nutrition by its ability to provide more and better information on responses to dietary stress in animals and their populations. © The Author 2014.

A single centre survey. To test: (i) awareness of nutrition screening tools and related care plans and; (ii) nutrition knowledge of doctors, nurses and dietitians working in spinal cord injuries (SCI) centres. The 14-item questionnaire was sent to 102 nurses, 17 doctors and 15 dietitians working in UK SCI centres during January-March 2010. Sixty-two (46.5%) questionnaires were completed and returned for analysis. The present audit demonstrated that awareness of the need for nutritional screening is good: 83% of staff reported that they are aware there is a nutrition screening tool. This audit also demonstrated areas of poor knowledge, such as calorie content of intravenous fluids, indicators of malnutrition, and choice of nutritional support in malnourished patients. All doctors, but only 38% of nurses, knew how to calculate body mass index. Surprisingly, nearly half (49%) of the participants thought that at least 20% weight loss was required to indicate malnutrition. This high-perceived cut-off point suggests that malnutrition is likely to continue to be undetected and unmanaged. The overall scores (median) showed clear differences in nutritional knowledge between groups (median: dietitians 92.8%; doctors 53.5%; nurses 35.7; Pnutrition. This study highlights the need for further education in SCI medicine in order to improve the efficacy of feeding and nutrition therapy for SCI patients.

Weight loss and malnutrition are common in cancer patients. Although weight loss is predominantly due to loss of fat mass, the morbidity risk is given by the decrease in muscle mass. The assessment of nutritional status is essential for a diagnosis of nutritional compromise and required for the multidisciplinary approach. Subjective global assessment (SGA) is made by the patients nutritional symptoms and weight loss. The objective assessment, a significant weight loss (>10%) for 6 months is considered an indicator of nutritional deficiency. The mean body index, body fat mass and body protein mass are decreased as cancer stage increases. The biochemical data of albumin, cholesterol, triglyceride, Zn, transferrin, total lymphocyte count are decreased in advanced cancer stage. Daily energy intake, cabohyderate and Vit B1 intake is decreased according to cancer stage. The patients are divided into three groups according to SGA. The three groups showed a significant difference in body weight, 1 month weight loss%, 6 month weight loss%, body mass index, mid arm circumference, albumin, energy intake, as well as carbohyderate intake protein and energy malnutrition. Nutritional assessment is of great importance because undernutrition has been shown to be associated with increase in stomach cancer associated morbidity and mortality. The authors concluded that nutritional assessment should be done in cancer patients preoperatively, and with adequate nutritional support, the morbidity and mortality would be decreased.

Disease-related malnutrition has deleterious consequences on patients' outcome and healthcare costs. The demonstration of improved outcome by appropriate nutritional management is on occasion difficult. The European Society of Clinical Nutrition and Metabolism (ESPEN) appointed the Nutrition Education Study Group (ESPEN-NESG) to increase recognition of nutritional knowledge and support in health services. To obtain the best available evidence on the potential effects of malnutrition on morbidity, mortality and hospital stay; cost of malnutrition; effect of nutritional treatment on outcome parameters and pharmaco-economics of nutritional therapy, a systematic review of the literature was performed following Cochrane methodology, to answer the following key questions: Q1) Is malnutrition an independent predictive factor for readmission within 30 days from hospital discharge? Q2) Does nutritional therapy reduce the risk of readmission within 30 days from hospital discharge? Q3) Is nutritional therapy cost-effective/does it reduce costs in hospitalized patients? and Q4) Is nutritional therapy cost effective/does it reduce costs in outpatients? For Q1 six of 15 identified observational studies indicated that malnutrition was predictive of re-admissions, whereas the remainder did not. For Q2 nine randomized controlled trials and two meta-analyses gave non-conclusive results whether re-admissions could be reduced by nutritional therapy. Economic benefit and cost-effectiveness of nutritional therapy was consistently reported in 16 identified studies for hospitalized patients (Q3), whereas the heterogeneous and limited corresponding data on out-patients (Q4) indicated cost-benefits in some selected sub-groups. This result of this review supports the use of nutritional therapy to reduce healthcare costs, most evident from large, homogeneous studies. In general, reports are too heterogeneous and overall of limited quality for conclusions on impact of malnutrition and its

We posit that maternal prenatal nutrition can influence offspring schizophrenia risk via epigenetic effects. In this article, we consider evidence that prenatal nutrition is linked to epigenetic outcomes in offspring and schizophrenia in offspring, and that schizophrenia is associated with epigenetic changes. We focus upon one-carbon metabolism as a mediator of the pathway between perturbed prenatal nutrition and the subsequent risk of schizophrenia. Although post-mortem human studies demonstrate DNA methylation changes in brains of people with schizophrenia, such studies cannot establish causality. We suggest a testable hypothesis that utilizes a novel two-step Mendelian randomization approach, to test the component parts of the proposed causal pathway leading from prenatal nutritional exposure to schizophrenia. Applied here to a specific example, such an approach is applicable for wider use to strengthen causal inference of the mediating role of epigenetic factors linking exposures to health outcomes in population-based studies.

Understanding, predicting and supressing the inadvertent aircraft oscillations caused by Aircraft/Rotorcraft Pilot Couplings (A/RPC) is a challenging problem for designers. These are potential instabilities that arise from the effort of controlling aircraft with high response actuation systems. The present paper reviews, updates and discusses desirable practices to be used during the design process for unmasking A/RPC phenomena. These practices are stemming from the European Commission project ARISTOTEL Aircraft and Rotorcraft Pilot Couplings - Tools and Techniques for Alleviation and Detection (2010-2013) and are mainly related to aerodynamic and structural modelling of the aircraft/rotorcraft, pilot modelling and A/RPC prediction criteria. The paper proposes new methodologies for precluding adverse A/RPCs events taking into account the aeroelasticity of the structure and pilot biodynamic interaction. It is demonstrated that high-frequency accelerations due to structural elasticity cause negative effects on pilot control, since they lead to involuntary body and limb-manipulator system displacements and interfere with pilot's deliberate control activity (biodynamic interaction) and, finally, worsen handling quality ratings.

The present systematic review and meta-analysis study evaluated the impact of early enteral nutrition (EN) on postoperative nutritional and immunological outcomes of gastric cancer (GC) patients. The databases of PubMed, Embase, Springer, and Cochrane library were searched till September 2016 to identify studies which evaluated the effects of EN compared with parenteral nutrition (PN) on postoperative immunological and nutritional status and hospitalization time in GC patients. Mean difference (MD) or standard mean difference (SMD) was calculated and I-square statistic test was used for heterogeneity analysis. The present systematic review and meta-analysis have consisted of seven trials, containing 835 GC patients. According to the result of meta-analysis, compared with PN, EN significantly resulted in more increase in the level of albumin [MD = 2.07 (0.49, 3.64)], prealbumin [MD = 9.41 (049, 33.55)], weight [MD = 1.52 (0.32, 2.72)], CD3+ [SMD = 1.96 (1.50, 2.43)], CD4+ [SMD = 2.45 (1.97, 2.93)], natural killers [MD = 5.80 (3.75, 7.85)], and also a decrease in the hospitalization time [MD=-2.39 (-2.74, -2.03)]. The results demonstrated that early administration of EN is more effective in improving postsurgical nutrition status and immune index in GC patients. So, based on these results, postoperative early administration of EN is recommended for GC patients where possible.

Chaparro, M Pia; Estrada, Leobardo

2012-09-01

The study objectives were to map the different stages of the nutrition transition for each department within Peru, and to determine the nutrition policy needs for each geographic area based on their current stage in the nutrition transition. Results show that most of the country is suffering from a double-burden of malnutrition, with high rates of stunting among children less than 5 years of age and high rates of overweight and obesity among women of reproductive age. Currently, Peru has only country-wide nutrition policies, administered by the Ministry of Health, that are primarily focused on stunting prevention. This study argues for the need to have decentralized nutrition policies that vary according to what type of malnutrition is being experienced in each geographic area.

Conservative Management of Mechanical Neck Pain in a Helicopter Pilot.

Science.gov (United States)

Alagha, Babak

2015-10-01

Acute and chronic spinal symptoms such as neck pain may limit flying performance significantly and disqualify the pilot from flight duty. Mechanical neck pain is very common among pilots because of their exposure to vibration, +GZ forces, helmet weight, poor neck posture during air combat maneuvers, previous neck injuries, and poor treatment plans for such injuries. Successful treatment of such injuries requires appropriate therapeutic procedures as well as an aeromedical assessment. The aim of this case study was to demonstrate the benefits of conservative procedures such as spinal manipulation and mobilization therapy (SMMT) and exercise therapy (ET) in treating chronic mechanical neck pain in an Iranian commercial helicopter pilot. A 36-yr-old male patient presented to the clinic with moderate, intermittent nonradicular chronic neck pain and limited range of motion over a 2-yr period. The patient was treated with cervical and upper thoracic SMMT followed by home ET for 5 wk. After this period, the patient reported significant recovery and improvement in range of motion in his neck. Mechanical neck pain is very common among helicopter pilots. Although Air Force and Navy waiver guides recommend nonsteroidal anti-inflammatory medications as well as SMMT and ET, there are currently very few published studies that examine the benefits of manual and exercise therapy for treating mechanical neck pain in commercial and military pilots. Based on the results of this study, it seems that SMMT and ET may be a safe and effective in treatment of uncomplicated mechanical neck pain in helicopter pilots. Alagha B.

Narasimhan Consulting Services, Inc. (NCS), under a contract with the Sandia National Laboratories (SNL), designed and operated pilot scale evaluations of the adsorption and coagulation/filtration treatment technologies aimed at meeting the recently revised arsenic maximum contaminant level (MCL) for drinking water. The standard of 10 {micro}g/L (10 ppb) is effective as of January 2006. The pilot demonstration is a project of the Arsenic Water Technology Partnership program, a partnership between the American Water Works Association Research Foundation (AwwaRF), SNL and WERC (A Consortium for Environmental Education and Technology Development). The pilot evaluation was conducted at Well 30 of the City of Weatherford, OK, which supplies drinking water to a population of more than 10,400. Well water contained arsenic in the range of 16 to 29 ppb during the study. Four commercially available adsorption media were evaluated side by side for a period of three months. Both adsorption and coagulation/filtration effectively reduced arsenic from Well No.30. A preliminary economic analysis indicated that adsorption using an iron oxide media was more cost effective than the coagulation/ filtration technology.

Airlie House Pollution Prevention Technology Transfer pilot projects

The projects were a series of pilot projects developed for DOE with the intention of transferring pollution prevention technology to private industry. The concept was to develop small technology transfer initiatives in partnership with the private sector. Argonne National Laboratory developed three projects: the microscale chemistry in education program, the microscale cost benefit study, and the Bethel New Life recycling trainee program. The two microscale chemistry projects focused on introducing microscale chemistry technologies to secondary and college education. These programs were inexpensive to develop and received excellent evaluations from participants and regulators. The recycle trainee project provided training for two participants and identified recycling and source reduction opportunities in Argonne`s solid waste stream. The pilot projects demonstrated that technology transfer initiatives can be developed and implemented with a small budget and within a short period of time. The essential components of the pilot projects were identification of target technologies that were already available, identification of target audiences, and a focus of effort to achieve a limited but defined objective.

1985-04-01

The Alpha Decontamination and Disassembly (AD and D) Pilot Facility was built to develop and demonstrate a reference process for the decontamination and size reduction of noncombustible transuranic (TRU) waste. The goals of the reference process were to remove >99% of the surface contamination to the high-level waste tanks, and to achieve volume reduction factors greater than 15:1. Preliminary bench-scale decontamination work was accomplished at Savannah River Laboratory (SRL), establishing a reference decontamination process. Initially, the pilot facility did not achieve the decontamination goals. As the program continued, and modifications to the process were made, coupon analysis idicated that 99% of the surface contamination was removed to the high-level drain system. Prior to the AD and D Pilot Facility, no size reduction work had been done at SRL. Several other Department of Energy (DOE) facilities were experimenting with plasma arc torches for size reduction work. Their methods were employed in the AD and D hot cell with moderate success. The experimental work concluded with recommendations for further testing of other size reduction techniques. 11 figs., 6 tabs

Market integration is an important source of cultural change exposing indigenous populations to epidemiologic and nutrition transitions. As children and adolescents are biologically sensitive to the health effects of market integration, we examine community variation of anthropometric indicators of nutritional status and growth among a cross-cultural sample of Kichwa, Shuar, Huaorani, and Cofán indigenous groups in the northern Ecuadorian Amazon. We measured height, weight, body mass index (BMI), upper arm circumference, and triceps skinfolds of 186 children and adolescents aged 2 to 18 years from seven communities. Anthropometric z-scores were calculated based on the National Health and Nutritional Examination Survey. Comparisons were made with this US reference group, along with between community differences to contextually explore the impacts of varying degrees of market integration. We found a high prevalence of stunting in both boys (40%) and girls (34%). Adiposity increased with age and 40% of girls between 15 and 18 years old were overweight. There were large sex differences in body composition with higher BMI, arm circumference, and triceps skinfolds in adolescent girls. The Kichwa demonstrated the poorest growth outcomes and nutritional stress followed by the Huaorani and Shuar; yet distinctions in under- and over-nutrition were evident within groups. Market integration is a major factor influencing the developmental and lifestyle mismatch associated with the epidemiologic and nutrition transition in general, and the dual burden pattern of high rates of stunting yet adequate to above average short-term nutritional status indicators found among indigenous Amazonian populations.

Clinical guidelines recommend that physicians counsel patients on diet and exercise; however, physician counseling remains suboptimal. To determine if incorporating performance improvement (PI) methodologies into a needs assessment for an internal medicine (IM) residency curriculum on nutrition and exercise counseling was feasible and enhanced our understanding of the curricular needs. One hundred and fifty-eight IM residents completed a questionnaire to assess their knowledge, attitudes, and practices (KAP) about nutrition and exercise counseling for hypertensive patients. Residents' baseline nutrition and exercise counseling rates were also obtained using chart abstraction. Fishbone diagrams were created by the residents to delineate perceived barriers to diet and exercise counseling. The KAP questionnaire was analyzed using descriptive statistics. Chart abstraction data was plotted on run charts and average counseling rates were calculated. Pareto charts were developed from the fishbone diagrams depicting the number of times each barrier was reported. Almost 90% of the residents reported counseling their hypertensive patients about diet and exercise more than 20% of the time on the KAP questionnaire. In contrast, chart abstraction revealed average counseling rates of 3% and 4% for nutrition and exercise, respectively. The KAP questionnaire exposed a clinical knowledge deficit, lack of familiarity with the national guidelines, and low self-efficacy. In contrast, the fishbone analysis highlighted patient apathy, patient co-morbidities, and time pressure as the major perceived barriers. We found that incorporating PI methods into a needs assessment for an IM residency curriculum on nutrition and exercise counseling for patients at risk of cardiovascular disease was feasible, provided additional information not obtained through other means, and provided the opportunity to pilot the use of PI techniques as an educational strategy and means of measuring outcomes.

One of the legacies of the nuclear weapon and nuclear power cycles has been the generation of large quantities of nuclear waste and fissile materials. As citizens of this planet, it is everyone's responsibility to provide for safe, secure, transparent, disposal of these waste nuclear materials. The Sandia Cooperative Monitoring Center sponsored a Transparency Monitoring Workshop where the use of the Waste Isolation Pilot Plant (WIPP) was identified as a possible transparency demonstration test bed. Three experiments were conceived as jumpstart activities to showcase the effective use of the WIPP infrastructure as a Transparency Demonstration Test Bed. The three experiments were successfully completed and demonstrated at the International Atomic Energy Association sponsored International Conference on Geological Repositories held in Denver Colorado November 1999. The design and coordination of these efforts is the subject of this paper

2010-12-31

To conduct a systematic review for the evidence supporting or disproving the reality of parenteral nutrition- antiepileptic drugs interaction, especially with respect to the plasma protein-binding of the drug. The articles related to the topic were identified through Medline and PubMed search (1968-Feburary 2010) for English language on the interaction between parenteral nutrition and antiepileptic drugs; the search terms used were anti-epileptic drugs, parenteral nutrition, and/or interaction, and/or in vitro. The search looked for prospective randomized and nonrandomized controlled studies; prospective nonrandomized uncontrolled studies; retrospective studies; case reports; and in vitro studies. Full text of the articles were then traced from the Universiti Sains Malaysia (USM) library subscribed databases, including Wiley-Blackwell Library, Cochrane Library, EBSCOHost, OVID, ScienceDirect, SAGE Premier, Scopus, SpringerLINK, and Wiley InterScience. The articles from journals not listed by USM library were traced through inter library loan. There were interactions between parenteral nutrition and drugs, including antiepileptics. Several guidelines were designed for the management of illnesses such as traumatic brain injuries or cancer patients, involving the use of parenteral nutrition and antiepileptics. Moreover, many studies demonstrated the in vitro and in vivo parenteral nutrition -drugs interactions, especially with antiepileptics. There was no evidence supporting the existence of parenteral nutrition-antiepileptic drugs interaction. The issue has not been studied in formal researches, but several case reports and anecdotes demonstrate this drug-nutrition interaction. However, alteration in the drug-free fraction result from parenteral nutrition-drug (i.e. antiepileptics) interactions may necessitate scrupulous reassessment of drug dosages in patients receiving these therapies. This reassessment may be particularly imperative in certain clinical situations

Full text: Nutrition counseling is one of the nutritional activities for improving child nutrition. It is the best way for decreasing malnutrition in children. Goal: To improve nutritional status of children under 6 through nutrition counseling in rural area with high prevalence of malnutrition. Methods: An international study with a total of 660 children with their mothers and with duration of seven months started in Lali district (in Khozestan province of Iran). Data gathered with using a demographic questionnaire and anthropometric measurements in children. Afterwards, malnourished children determined and referred to nutrition counseling centers. After training mothers, planning a diet and monitoring nutritional status were determined. Results: The prevalence of stunting, wasting and underweight in studied children at the beginning of the study were 9.6%, 6.2% and 4.8% respectively, which reached 8.7%, 3.3% and 2.4% by the end of the project (P<0.05). The intervention was most efficient in children suffering growth retardation, with a cure rate of 91%; only 48.6% of malnourished children referred to the center health were cured. Conclusion: Results obtained from this study showed that over 90% of children suffering growth retardation were cured. This means establishing nutrition counseling centers to encourage proper nutrition behaviors, evaluate current issues and find possible solutions, persuade mothers to improve child nutrition status making use of practical and specific methods appropriate with the tradition of the region has had an important role in improving the nutrition status of the children in the region.

Cachexia is a multifatorial syndrome characterized by loss of body weight, fat and muscle, increasing morbidity and mortality. The use of an index accounting for both serum albumin and C Reactive Protein levels could make early identification of cachexia easier. To evaluate the variation of an inflammatory nutritional index related to nutritional status in cancer patients. Cross sectional study including patients with gastrointestinal and lung cancer of a public chemotherapy service in Brazil. Serum albumin and C Reactive Protein were measured and the nutritional status was defined by Subjective Global Assessment. Statistical analyses were performed using Stata 9.2(TM). A total of 74 patients were evaluated, 58.1% of them were male, mean age 63.4 ± 11.9 years old. Gastrointestinal cancer was the most prevalent type (71.6%). Only 13.7% of the patients were well nourished and 21.9% were severely malnourished. C Reactive Protein significantly increased according to nutritional status decline (p=0.03). When the albumin from patients with systemic inflammation was evaluated, there was no significant variation in relation to nutritional status (p=0.06). The Inflammatory Nutritional Index significantly varied in relation to nutritional status independent of the systemic inflammation (p=0.02). Inflammatory Nutritional Index can be an adjuvant way for biochemical nutritional assessment and follow up in cancer patients with systemic inflammation. Copyright © AULA MEDICA EDICIONES 2013.

In this paper, a random chaotic pilot interval and permutations scheme without any requirement of redundant sideband information is firstly proposed for the physical layer security-enhanced intensity modulation direct detection orthogonal frequency division multiplexing passive optical network (IMDD-OFDM-PON) system. With the help of the position feature of inserting the pilot, a simple logistic chaos map is used to generate the random pilot interval and scramble the chaotic subcarrier allocation of each column pilot data for improving the physical layer confidentiality. Due to the dynamic chaotic permutations of pilot data, the enhanced key space of ∼103303 is achieved in OFDM-PON. Moreover, the transmission experiment of 10-Gb/s 16-QAM encrypted OFDM data is successfully demonstrated over 20-km single-mode fiber, which indicates that the proposed scheme not only improves the system security, but also can achieve the same performance as in the common IMDD-OFDM-PON system without encryption scheme.

Nutritional status among adolescents is an important health indicator. The up-to-date information about nutritional status and food consumption pattern in the remote rural area is required for the effective public health intervention in the rural area of the country. The present study aimed to demonstrate the prevalence of malnutrition, eating behavior and nutritional knowledge among secondary school students in a remote rural area in Thailand. Body weight and height data were collected from 298 secondary school students for nutritional status calculation using the Institute of Nutrition Research, Mahidol University, INMU-Thaigrowth program. Eating behavior and nutritional knowledge were observed by self-administrated questionnaires. The prevalence low height-for-age (instant noodles (64.4%). The prevalence of malnutrition was low among this population. The studied population had a fair knowledge about nutrition. The authoes found that regular consumption of highly commercialized snack products especially salted chips and instant noodles were at a high level in this remote rural area of Thailand. The pattern of nutritional problems in Thailand may have changed in which a public health program for children in rural areas of the country should recognize this transition.

[Does nutrition matter? Why nutritional care is neglected in Italian hospitals?].

Science.gov (United States)

Lucchin, Lucio

2015-02-01

It is surprising how little attention nutrition has received from healthcare providers, in particular in the hospital environment. The discipline of nutrition is also no longer included in regular graduate courses in medicine. The underlying causes of this phenomenon are hard to determine, but they are part of the current paradigmatic shift underway in medicine. Nutrition is a complex and challenging science for most care givers, as it also pertains to their behaviours that should be consistent with health and nutrition messages they deliver to patients. The clinical and economic impact is of great relevance, raising serious ethical issues if not adequately addressed. It is time to re-establish at least a basic level of appropriate nutrition prescription beyond general counseling, with the aim to restore the integrity of the doctor-patient relationship.

[Esthetic nutrition: body and beauty enhancement through nutritional care].

Witt, Juliana da Silveira Gonçalves Zanini; Schnider, Aline Petter

2011-09-01

Nowadays, there is an increasing quest for beauty and the models proposed by fashion goods and service segments, to achieve the perfect body. The standard of beauty corresponds to a thin body, without considering health aspects. The number of women who go on diets to control weight is increasing; and taking this into consideration the objective of this study is to conduct a bibliographical review and extract data on esthetics and body image to support the practice of nutritional care. Socio-cultural aspects, which motivate the quest for the perfect body, as well as body, beauty, esthetics, nutritional counseling and cognitive behavior therapy were examined in this survey. On the basis of this work, it is possible to conclude that the continuing obsession with the body may lead the person to go on diets and other drastic methods to control weight, such as surgical procedures. In this respect, nutritional care is far more than merely recommending a standard diet or giving information, as it represents providing an effective model for nutritional reeducation, prioritizing improvement in the style and quality of life. This article provides data about enhancing esthetics and beauty by means of appropriate nutrition.

Full Text Available In spite of amazing progress in food supply and nutritional science, and a striking increase in life expectancy of approximately 2.5 months per year in many countries during the previous 150 years, modern nutritional research has a great potential of still contributing to improved health for future generations, granted that the revolutions in molecular and systems technologies are applied to nutritional questions. Descriptive and mechanistic studies using state of the art epidemiology, food intake registration, genomics with single nucleotide polymorphisms (SNPs and epigenomics, transcriptomics, proteomics, metabolomics, advanced biostatistics, imaging, calorimetry, cell biology, challenge tests (meals, exercise, etc., and integration of all data by systems biology, will provide insight on a much higher level than today in a field we may name molecular nutrition research. To take advantage of all the new technologies scientists should develop international collaboration and gather data in large open access databases like the suggested Nutritional Phenotype database (dbNP. This collaboration will promote standardization of procedures (SOP, and provide a possibility to use collected data in future research projects. The ultimate goals of future nutritional research are to understand the detailed mechanisms of action for how nutrients/foods interact with the body and thereby enhance health and treat diet-related diseases.

In spite of amazing progress in food supply and nutritional science, and a striking increase in life expectancy of approximately 2.5 months per year in many countries during the previous 150 years, modern nutritional research has a great potential of still contributing to improved health for future generations, granted that the revolutions in molecular and systems technologies are applied to nutritional questions. Descriptive and mechanistic studies using state of the art epidemiology, food intake registration, genomics with single nucleotide polymorphisms (SNPs) and epigenomics, transcriptomics, proteomics, metabolomics, advanced biostatistics, imaging, calorimetry, cell biology, challenge tests (meals, exercise, etc.), and integration of all data by systems biology, will provide insight on a much higher level than today in a field we may name molecular nutrition research. To take advantage of all the new technologies scientists should develop international collaboration and gather data in large open access databases like the suggested Nutritional Phenotype database (dbNP). This collaboration will promote standardization of procedures (SOP), and provide a possibility to use collected data in future research projects. The ultimate goals of future nutritional research are to understand the detailed mechanisms of action for how nutrients/foods interact with the body and thereby enhance health and treat diet-related diseases.

Recent research has begun to examine the early maladaptive schemas of substance abusers, as it is believed that targeting these core beliefs in treatment may result in improved substance use outcomes. One special population that has received scant attention in the research literature, despite high levels of substance use, is airline pilots. The current study examined the early maladaptive schemas of a sample of airline pilots ( n = 64) who were seeking residential treatment for alcohol dependence and whether they differed in early maladaptive schemas from non-pilot substance abusers who were also seeking residential treatment for alcohol dependence ( n = 45). Pre-existing medical records from patients of a residential substance abuse treatment facility were reviewed for the current study. Of the 18 early maladaptive schemas, results demonstrated that pilots scored higher than non-pilots on the early maladaptive schema of unrelenting standards (high internalized standards of behavior), whereas non-pilots scored higher on insufficient self-control (low frustration tolerance and self-control). Early maladaptive schemas may be a relevant treatment target for substance abuse treatment seeking pilots and non-pilots.

The multidisciplinary nature of nutrition research is one of its main strengths. At the same time, however, it presents a major obstacle to integrate data analysis, especially for the terminological and semantic interpretations that specific research fields or communities are used to. To date, a proper ontology to structure and formalize the concepts used for the description of nutritional studies is still lacking. We have developed the Ontology for Nutritional Studies (ONS) by harmonizing selected pre-existing de facto ontologies with novel health and nutritional terminology classifications. The ONS is the result of a scholarly consensus of 51 research centers in nine European countries. The ontology classes and relations are commonly encountered while conducting, storing, harmonizing, integrating, describing, and searching nutritional studies. The ONS facilitates the description and specification of complex nutritional studies as demonstrated with two application scenarios. The ONS is the first systematic effort to provide a solid and extensible formal ontology framework for nutritional studies. Integration of new information can be easily achieved by the addition of extra modules (i.e., nutrigenomics, metabolomics, nutrikinetics, and quality appraisal). The ONS provides a unified and standardized terminology for nutritional studies as a resource for nutrition researchers who might not necessarily be familiar with ontologies and standardization concepts.

Recent attempts to improve the healthfulness of away-from-home eating include regulations requiring restaurants to post nutrition information. The impact of such regulations on restaurant environments is unknown. To examine changes in restaurant environments from before to after nutrition-labeling regulation in a newly regulated county versus a nonregulated county. Using the Nutrition Environment Measures Survey-Restaurant version audit, environments within the same quick-service chain restaurants were evaluated in King County (regulated) before and 6 and 18 months after regulation enforcement and in Multnomah County (nonregulated) restaurants over a 6-month period. Data were collected in 2008-2010 and analyses conducted in 2011. Overall availability of healthy options and facilitation of healthy eating did not increase differentially in King County versus Multnomah County restaurants aside from the substantial increase in onsite nutrition information posting in King County restaurants required by the new regulation. Barriers to healthful eating decreased in King County relative to Multnomah County restaurants, particularly in food-oriented establishments. King County restaurants demonstrated modest increases in signage that promotes healthy eating, although the frequency of such promotion remained low, and the availability of reduced portions decreased in these restaurants. The healthfulness of children's menus improved modestly over time, but not differentially by county. A restaurant nutrition-labeling regulation was accompanied by some, but not uniform, improvements in other aspects of restaurant environments in the regulated compared to the nonregulated county. Additional opportunities exist for improving the healthfulness of away-from-home eating beyond menu labeling. Copyright © 2012 American Journal of Preventive Medicine. Published by Elsevier Inc.

The Energy research Centre of the Netherlands (ECN) has developed a biomass gasification technology, called the MILENA technology. The Milena gasification technology has a high cold gas efficiency and high methane yield, making it very suitable for gas engine and turbine applications as well as upgrading of the gas into Bio-Methane. An overall efficiency from biomass to power of over 30% is possible, whereas 70% efficiency is achievable from biomass to gas grid quality methane. HVC Group (situated in Alkmaar, North Holland) is a modern public service waste company. HVC converts waste streams which cannot be recycled into usable forms of energy. HVC has a 75 MWth waste wood boiler in operation which produces heat and electricity, and an anaerobic digester which converts domestic fruit, vegetable and garden waste into Bio-Methane. HVC expects an important role for Bio-Methane in the future and HVC has decided to join ECN with the development, demonstration and implementation of the MILENA Bio-Methane technology. Linked to the Bio-Methane demonstration project is the Netherlands Expertise Centre for Biomass Gasification. The MILENA demonstration project and the Gasification Expert Centre are supported by the following companies and organizations: HVC, TAQA, Gasunie, Dahlman, province of North Holland, the Alkmaar municipality and ECN. In 2010 and 2012 extensive lab-scale and pilot scale tests have been executed by ECN and HVC to proof that the gasification and gas cleaning technology is ready for commercial application. The final step in this test program was a duration test in the 800 kWth MILENA pilot plant coupled to the OLGA tar removal unit. The goal was to show high availability. The result of the test was an availability of the gasifier of 96% and an overall availability (including gas cooling and gas cleaning) of 85%. The results of the duration tests convinced HVC and the other partners that the technology is ready for scale-up. The results produced in the

Maternal nutritional health, before and during pregnancy, influences the health status of herself and her developing fetus. Pregnancy is an important condition for improving nutritional knowledge. The present study aimed at determining effects of nutrition education on levels of nutritional awareness of a representative group of pregnant women in Western Iran. A quasi-experimental intervention was undertaken on a random sample of pregnant women (n = 100) attending urban health centers in Ilam city (western Iran) during the year 2011 for prenatal care. A nutritional education program containing two to four lessons was undertaken for small groups of between six to ten women. Nutritional knowledge was assessed before intervention (pretest) and followed by two posttests within three weeks interval. The awareness level of pregnant women about healthy nutrition was significantly increased from 3% before intervention to 31% after the nutritional education intervention (P nutritional education intervention will have a positive effect on nutritional awareness of pregnant women.

Poor dietary intake is the most important behavioural risk factor affecting health globally. Despite this, there has been little investment in public health nutrition policy actions. Policy process theories from the field of political science can aid understanding why policy decisions have occurred and identify how to influence ongoing or future initiatives. The present review aims to examine public health nutrition policy literature and identify whether a policy process theory has been used to analyse the process. Electronic databases were searched systematically for studies examining policy making in public health nutrition in high-income, democratic countries. International, national, state and local government jurisdictions within high-income, democratic countries. Individuals and organisations involved in the nutrition policy-making process. Sixty-three studies met the eligibility criteria, most were conducted in the USA and a majority focused on obesity. The analysis demonstrates an accelerating trend in the number of nutrition policy papers published annually and an increase in the diversity of nutrition topics examined. The use of policy process theory was observed from 2003; however, it was utilised by only 14 % of the reviewed papers. There is limited research into the nutrition policy process in high-income countries. While there has been a small increase in the use of policy process theory from 2003, an opportunity to expand its use is evident. We suggest that nutrition policy making would benefit from a pragmatic approach that ensures those trying to influence or understand the policy-making process are equipped with basic knowledge around these theories.

Although enteral nutrition is considered the preferred strategy for nutrition support, it is often precluded by nasogastric feeding intolerance or the inability to place feeding access into the postpyloric position. In an effort to improve enteral nutrition (EN) outcomes at our institution, the nutrition support dietitian (NSD) began placing postpyloric feeding tubes (PPFT) in intensive care unit patients. Intensive care unit patients who received blind, bedside PPFT placements by the NSD (n = 18) were compared with a concurrent age- and diagnosis-matched control group that received standard nutritional care without NSD intervention (n = 18). Interruption of EN infusion, appropriateness of parenteral nutrition (PN) prescription (based on American Society of Parenteral and Enteral Nutrition guidelines), and incidence of ventilator-associated pneumonia (VAP), as defined by the American College of Chest Physicians practice guidelines, were determined in each group. The NSD was successful in positioning the PPFT at or distal to the third portion of the duodenum in 83% of attempts. The PPFT group demonstrated no interruption of enteral feeding compared with 56% in the control group (p VAP in the PPFT group (6% vs 28%, p = .07). Of the PN initiations in the control group, 88% were deemed to be potentially avoidable; 6 of 8 PNs were initiated because of gastric residuals. Enteral nutrition facilitated by NSD placement of postpyloric feeding access is associated with improved tube feeding tolerance and reduced PN use. Further studies are needed to evaluate a possible effect of postpyloric feeding on the incidence of VAP.

Ethical issues in nutritional support nursing. Withholding and withdrawing nutritional support.

Science.gov (United States)

Knox, L S

1989-06-01

A new and controversial debate in bioethics concerns the question, "Is it ever acceptable to withhold or withdraw specialized nutritional support from the dying adult patient?" In the opinion of many, the answer to this question is yes, but for only a very small number of patients. Provision of nutrition through artificial means is an invasive medical intervention. As such, procedures for supplying nutritional support impose burdens as well as provide benefits and may, under certain circumstances, be foregone. However, the needs of the vast majority of dying patients will best be served by providing specialized nutritional support.
