    Among families who have young children, feeding concerns are quite common (Brazelton, 1992). Feeding concerns can include, but are not limited to, inappropriate mealtime behaviors, lack of self-feeding, food selectivity, and food refusal (Kerwin, 1999). Given the complex nature of assessment of and intervention for feeding concerns in young…

    Normal motor function is dependent on the highly regulated synthesis and release of the transmitter dopamine by neurons projecting from the substantia nigra to the corpus striatum. Parkinson's disease involves the progressive degeneration of these neurons. Its core symptoms are a direct consequence of a striatal insufficiency of intrasynaptic dopamine. Levodopa, the standard of care for the treatment of PD, acts after its conversion to dopamine by restoring striatal dopaminergic transmission. However, there are significant differences between the normally functioning dopamine system and the restoration of function provided by standard levodopa treatment. Increasing clinical and preclinical evidence suggests that the intermittent stimulation of dopamine receptors resulting from current therapeutic regimens contributes to the response complications that ultimately affect most parkinsonian patients. It now appears that chronic nonphysiologic stimulation of dopaminergic receptors on striatal GABAergic neurons activates characteristic signaling pathways, leading to a potentiation of the synaptic efficacy of adjacent glutamatergic receptors of the N-methyl-D-aspartate (NMDA) subtype. As a result, function of these GABAergic efferent neurons changes in ways that favor the appearance of motor complications. Conceivably, use of dopaminomimetic replacement strategies that provide more continuous dopamine receptor stimulation will act to prevent or alleviate these disabling complications. A number of promising approaches to achieving this goal are now under development.

    Mothers who are concerned about their young child's weight are more likely to use restrictive feeding, which has been associated with increased food seeking behaviors, emotional eating, and overeating in young children across multiple prospective studies. In the present study, we examined whether mothers' intuitive eating behaviors would moderate the association between their concern about their child's weight and their use of restrictive feeding. In a sample of 180 mothers of young children, two maternal intuitive eating behaviors (i.e., eating for physical reasons, trust in hunger and satiety cues) moderated this association after controlling for maternal age, body mass index, years of education, race/ethnicity, awareness of hunger and satiety cues and perceptions of child weight. More specifically, concern about child weight was unrelated to restrictive feeding for mothers with higher levels of eating for physical reasons and trust in hunger and satiety cues. However, concern about child weight was positively related to restrictive feeding among mothers with lower or average levels of eating for physical reasons and trust in hunger and satiety cues. These findings indicate that it may be important address maternal intuitive eating within interventions designed to improve self-regulated eating in children, as mothers who attend these interventions tend to be highly concerned about their child's weight and, if also low in intuitive eating, may be at risk for using restrictive feeding behaviors that interfere with children's self-regulated eating.

    Full Text Available To analyse the association in newborns between blood levels of phenylalanine and feeding method and gestational age.This observational, cross-sectional study included a sample of 11,829 infants between 2008 and 2013 in a Spanish region. Data were recorded on phenylalanine values, feeding method [breast, formula, mixed (breast plus formula, or partial or fully intravenous feeding], gestational age in weeks (<32, 32-37, ≥37, gender and days since birth at the moment of blood collection. Outcomes were [phenylalanine] and [phenylalanine] ≥95th percentile. Associations were analysed using multivariate models [linear (means difference and logistic regression (adjusted odds ratios].Higher phenylalanine values were associated with lower gestational age (p<0.001 and with intravenous feeding (p<0.001.The degree of prematurity and intravenous feeding influenced the plasma concentration of phenylalanine in the newborn. Caution should be taken in [phenylalanine] for newborns with intravenous feeding, monitoring them carefully. Very preterm infants given the recommended amount of amino acids should also be strictly monitored. These findings should be taken into consideration and call for adapting the amounts to the needs of the infant.

    Transport of large neutral amino acids (LNAA) across the blood brain barrier (BBB) is facilitated by the L-type amino acid transporter, LAT1. Peripheral accumulation of one LNAA (e.g., phenylalanine (phe) in PKU) is predicted to increase uptake of the offending amino acid to the detriment of others, resulting in disruption of brain amino acid homeostasis. We hypothesized that selected non-physiological amino acids (NPAAs) such as DL-norleucine (NL), 2-aminonorbornane (NB; 2-aminobicyclo-(2,1,1)-heptane-2-carboxylic acid), 2-aminoisobutyrate (AIB), and N-methyl-aminoisobutyrate (MAIB), acting as competitive inhibitors of various brain amino acid transporters, could reduce brain phe in Pah (enu2) mice, a relevant murine model of PKU. Oral feeding of 5 % NL, 5 % AIB, 0.5 % NB and 3 % MAIB reduced brain phe by 56 % (p amino acids) were also observed, however, with MAIB displaying the mildest effects. Of interest, MAIB represents an inhibitor of the system A (alanine) transporter that primarily traffics small amino acids and not LNAAs. Our studies represent the first in vivo use of these NPAAs in Pah (enu2) mice, and provide proof-of-principle for their further preclinical development, with the long-term objective of identifying NPAA combinations and concentrations that selectively restrict brain phe transport while minimally impacting other LNAAs and downstream intermediates.

    Full Text Available The paper summarises the work done in the framework of two R&D projects aimed to demonstrate the contribution of Near Infrared Spectroscopy (NIRS to help the enforcement of the European legislation governing the use of animal by-products in animal feeds. Three different types of animal feed products were studied: compound feeds (CFs, animal protein byproducts meals (APBPs and animal fats by-products (AFBPs. The quantitative and qualitative chemometric models produced with a large collection of compound feed samples (n = 1005 ground and 523 unground have demonstrated, that NIRS can be used for the detection and quantification of the meat and bone meal (MBM added to compound feeds. Discriminant models produced with unground samples produced 100% of correctly classified samples in two cloned instruments placed in two different locations. The results also show that two dimensions NIR spectra of Animal By-Products (ABP, animal meals and fats may contain information about the animal species or group of species from which the ABPs were produced. However, further work is needed to enlarge the sample bank and the spectral libraries with well authenticated samples in order to increase the robustness of the quantitative and qualitative NIRS models. The paper opens expectations for using NIRS for the enforcement of legislation concerning the use of ABPs in animal feeds. More research and demonstration efforts have to be done in order to obtain more definitive and robust predictive models and for optimising its implementation either at-line, on-line and in-line in feed factories and inspection laboratories.

    Objectives To examine the relationship between maternal stress, work status, concern about child weight, and the use of restrictive feeding practices among mothers of preschool children. Methods 285 mothers of 2-to-5-year-old children completed an on-line survey. Questions included demographics, items from the Depression Anxiety Stress Scale, and the Child Feeding Questionnaire. Linear regression and ANOVA examined the relationship between maternal stress, work hours, concern about child weight, and the use of restrictive practices for one 2-to-5-year-old child living within the home. Results Mothers were 32.6 ± 5.2 years of age and spent 39.7 ± 12.0 h/week at work. Seventy-one percent worked full time. Children were 3.4 ± 1.0 years of age and 51% male. Stress (3.41 ± 0.77, p ≤ 0.001) and concern about child weight (3.41 ± 0.77, p ≤ 0.00) were associated with the use of restrictive feeding practices. Mothers with severe/extremely severe stress used restriction more than mothers with normal stress, respectively (3.63 ± 0.80, 3.30 ± 0.81, p = 0.03). No difference was found among mothers with mild/moderate stress (3.50 ± 0.63, p = 0.06). There was no association between work hours (p = 0.50) or work status (p = 0.91) and the use of restrictive feeding practices. Conclusions Maternal stress and concern about child weight were associated with the use of restrictive feeding practices. Considering the current rates of childhood obesity in the United States, understanding factors that influence a child's food environment is advantageous and can help improve maternal and child health.

    Since the U.S. Food and Drug Administration approved ractopamine hydrochloride and zilpaterol hydrochloride in animal feeds, usage of those compounds has been a topic of worldwide debate. Ractopamine and zilpaterol are β-adrenergic agonists used as veterinary drugs to increase weight gain in certain animals raised for food. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) established maximum residue limits for ractopamine, which were adopted by the Codex Alimentarius Commission (Codex). No maximum residue limits for zilpaterol have been adopted by JECFA, and new reports of animal mobility issues confront the use of this feed additive. However, many countries disagree with the Codex standards and are restricting or banning meat products containing β agonists. The bans by major importers of U.S. meat products have prompted some to advocate that the United States use the World Trade Organization dispute settlement body. This paper looks at the developments to provide a fuller accounting of what the issues may mean to U.S. firms selling meat products containing residues of β agonists.

  13. Feeding live invertebrate prey in zoos and aquaria: Are there welfare concerns?

    2017-09-01

    Invertebrates constitute more than 90% of all species on earth, however, as a rule, humans do not regard invertebrates as creatures that can suffer and they are generally seen as creatures that should be eliminated. As a result, the importance of their welfare may be grossly unappreciated. For instance, the feeding of live food is often viewed as a good method of enrichment and invertebrates are commonly used as live prey in many zoological facilities. As a result, zoos may send mixed messages to their patrons in that welfare is considered only for the invertebrates that are part of their zoological collection and not necessarily for the invertebrates used as feed. Research indicates that many invertebrates possess nociceptors, opioid receptors, and demonstrate behavioral responses indicative of pain sensation. In addition, in some taxa, there may be evidence of higher cognitive functions such as emotions and learning, although studies in this area of research are preliminary and sparse. Therefore, the possibility for suffering exists in many invertebrate species and as such, zoological facilities have an ethical responsibility to take their welfare into consideration. This paper discusses the current research regarding invertebrates' capacity for suffering and discusses methods facilities can use to improve the welfare of their invertebrate live prey. © 2017 Wiley Periodicals, Inc.

    The flood that hit Kelantan in December 2014 was the worst in Malaysian history. Women and their infants accounted for a large proportion of the people at risk who were badly affected, as almost half of the population in Kelantan was in the reproductive age group. This report serves to raise awareness that breastfeeding mothers and infants are a special population with unique needs during a disaster. Four of their concerns were identified during this massive flood: first, the negative impact of flood on infant nutritional status and their health; second, open space and lack of privacy for the mothers to breastfeed their babies comfortably at temporary shelters for flood victims; third, uncontrolled donations of infant formula, teats, and feeding bottles that are often received from many sources to promote formula feeding; and lastly, misconceptions related to breastfeeding production and quality that may be affected by the disaster. The susceptibility of women and their infant in a natural disaster enhances the benefits of promoting the breastfeeding rights of women. Women have the right to be supported which enables them to breastfeed. These can be achieved through monitoring the distribution of formula feeding, providing water, electricity and medical care for breastfeeding mothers and their infants. A multifaceted rescue mission team involving various agencies comprising of local government, including the health and nutrition departments, private or non-governmental organizations and individual volunteers have the potential to improve a satisfactory condition of women and infants affected by floods and other potential natural disasters.

    Thirty-six feed phosphates, including nine mono-dicalcium phosphates (M-DCP, 21% P), 13 di-monocalcium phosphates (D-MCP, 18.5% P), and 14 thermochemically produced defluorinated phosphates (DFP, 18.0% P), were analyzed for moisture, Ca, P, and 9 essential minerals (K, Mg, Na, Cl, Fe, Cu, Mn, Se, and Zn). Also, nine potentially toxic elements (Al, F, As, Cd, Cr, Hg, Pb, Ni, and V) were determined. All of the M-DCP were of domestic origin; 5 of the 13 D-MCP samples were obtained in Algeria, Peru, Holland, and South Africa. The DFP samples included 10 domestic products, 2 samples from Russia, 1 from Poland, and 1 from Japan. Levels of Na were high in the DFP samples (3.96 to 5.78%), except for the two Russian samples, which contained only .16 and .19%. Magnesium levels varied from .09 to .76%, .02 to 1.21%, and .01 to 1.54% in the M-DCP, D-MCP, and DFP samples, respectively. Two Russian DFP samples contained 1.51 and 1.54% Mg. Chlorine levels were generally quite low (.002 to .020%); however, two precipitated D-MCP samples contained .12 and 1.47% Cl. Iron levels were high (.24 to 1.41%) in all samples except the bone-precipitated D-MCP (.039%), and the reference standard, calcium phosphate, dibasic dihydrate, USP (.029%). Levels of Cu, Mn, and Zn were quite variable. Cadmium varied from DCP. Vanadium levels varied from 20 to 796 ppm in one experimental M-DCP sample. Fluorine levels were in the acceptable range, .05 to .21%.(ABSTRACT TRUNCATED AT 250 WORDS)

    Full Text Available There is an urgent need to study in Europe the plant exposure to mycotoxin risk due to the identification of new toxigenic species, the continuous evolution of species profile on the food crops and climate changes that influence the quality of level of toxigenic fungi colonization of plant hosts. In particular, Fusarium and Aspergillus problem in Europe has enormous importance; recent epidemics in wheat in some areas of Northern and Central Europe and in grape in southern Europe have brought this problem into focus again. This concern has driven many efforts at EU level aimed to harmonize strategies for mycotoxinreduction in food and feed chain. This is the target of a large collaborative project of four-year duration (MYCORED as acronym, that was approved within the European FP7- Food, Agriculture, and Biotechnologies Work Programmes (www.mycored.eu. MYCORED aims to develop strategic solutions for reducing mycotoxin contamination in major crops. Novel methodologies, efficient handling procedures and information/dissemination, and educational strategies are considered in a context of multidisciplinary integration of know-how and technology to reduce mycotoxin exposure worldwide. The direct involvement of ICPC countries (Argentina, Egypt, Russia, South Africa and international organizations (CIMMYT, IITA together with strong scientific alliances with international experts and national and international societies for mycotoxicology is a strong point of the project through sharing experiences and resources from several past/ongoing mycotoxin projects in a global context. Similarly, the International Society for Mycotoxicology (ISM (http://www.mycotoxsociety. org aims at increasing scientific knowledge concerning biology, chemistry and any sciences/disciplines related to mycotoxins and toxigenic fungi, through membership networking, scientific meetings, symposia, discussions, technical courses and publications.

    For many years, protecting the fetus has been a concern of the National Council on Radiation Protection and Measurements (NCRP) and the International Commission on Radiological Protection (ICRP). Early recommendations focused on the possibility of a wide variety of detrimental developmental effects while later recommendations focused on the potential for severe mental retardation and/or reduction in the intelligence quotient (I.Q.). The latest recommendations also note that the risk of cancer for the fetus is probably two to three times greater per Sv than in the adult. For all these reasons, the NCRP and the ICRP have provided guidance to physicians on taking all reasonable steps to ascertain whether any woman requiring a radiological or nuclear medicine procedure is pregnant or nursing a child. The NCRP and the ICRP also advise the clinician to postpone such procedures until after delivery or cessation of nursing, if possible.

    Confined goats spend a substantial part of the day feeding. A poorly designed feeding place increases the risk of feeding in nonphysiological body postures, and even injury. Scientifically validated information on suitable dimensions of feeding places for loose-housed goats is almost absent from the literature. The aim of the present study was, therefore, to determine feeding place dimensions that would allow goats to feed in a species-appropriate, relaxed body posture. A total of 27 goats with a height at the withers of 62 to 80 cm were included in the study. Goats were tested individually in an experimental feeding stall that allowed the height difference between the feed table, the standing area of the forelegs, and a feeding area step (difference in height between forelegs and hind legs) to be varied. The goats accessed the feed table via a palisade feeding barrier. The feed table was equipped with recesses at varying distances to the feeding barrier (5-55 cm in 5-cm steps) at angles of 30°, 60°, 90°, 120°, or 150° (feeding angle), which were filled with the goats' preferred food. In 18 trials, balanced for order across animals, each animal underwent all possible combinations of feeding area step (3 levels: 0, 10, and 20 cm) and of difference in height between feed table and standing area of forelegs (6 levels: 0, 5, 10, 15, 20, and 25 cm). The minimum and maximum reach at which the animals could reach feed on the table with a relaxed body posture was determined for each combination. Statistical analysis was performed using mixed-effects models. The animals were able to feed with a relaxed posture when the feed table was at least 10 cm higher than the standing height of the goats' forelegs. Larger goats achieved smaller minimum reaches and minimum reach increased if the goats' head and neck were angled. Maximum reach increased with increasing height at withers and height of the feed table. The presence of a feeding area step had no influence on minimum and

    A priority of the European Union is the control of risks possibly associated with chemical contaminants in food and undesirable substances in feed. Following an initial chapter describing the main contaminants detected in food and undesirable substances in feed in the EU, their main sources and the factors which affect their occurrence, the present review focuses on the "continous call for data" procedure that is a very effective system in place at EFSA to make possible the exposure assessment of specific contaminants and undesirable substances. Risk assessment of contaminants in food atances in feed is carried currently in the European Union by the CONTAM Panel of EFSA according to well defined methodologies and in collaboration with competent international organizations and with Member States.

  6. Bridgman's concern

    1993-07-01

    In 1956 P.W. Bridgman published a letter to the editor in the Journal of Applied Physics reporting results of electrical resistance measurements on iron under static high pressure. The work was undertaken to verify the existence of a polymorphic phase transition at 130 kbar (13 GPa) reported in the same journal and year by the Los Alamos authors, Bancroft, Peterson and Minshall for high pressure, shock-compression loading. In his letter, Bridgman reported that he failed to find any evidence for the transition. Further, he raised some fundamental concerns as to the state of knowledge of shock-compression processes in solids. Later it was determined that Bridgman's static pressure scale was in error, and the shock observations became the basis for calibration of pressure values in static high pressure apparatuses. In spite of the error in pressure scales, Bridgman's concerns on descriptions of shock-compression processes were perceptive and have provided the basis for subsequent fundamental studies of shock-compressed solids. The present paper, written in response to receipt of the 1993 American Physical Society Shock-Compression Science Award, provides a brief contemporary assessment of those shock-compression issues which were the basis of Bridgman's 1956 concerns.

  7. Feed safety in the feed supply chain

    2011-01-01

    Full Text Available A number of issues have weakened the public's confidence in the quality and wholesomeness of foods of animal origin. As a result farmers, nutritionists, industry and governments have been forced to pay serious attention to animal feedstuff production processes, thereby acknowledging that animal feed safety is an essential prerequisite for human food safety. Concerns about these issues have produced a number of important effects including the ban on the use of processed animal proteins, the ban on the addition of most antimicrobials to farm animals diets for growth‐promotion purposes, and the implementation of feed contaminant regulations in the EU. In this context it is essential to integrate knowledge on feed safety and feed supply. Consequently, purchase of new and more economic sources of energy and protein in animal diets, which is expected to conform to adequate quality, traceability, environmental sustainability and safety standards, is an emerging issue in livestock production system.

    This series of A-level social biology topic books responds to the changing demands of social biology syllabuses, with each text dealing with a particular area of interest. Although the series is primarily intended for students of A-level social biology, the books will appeal to students studying a wide range of biological subjects at A-level. Environmental Concerns covers topics common to several A-level human and social biology syllabuses. It is particularly relevant to the human ecology and conservation options. The text focuses on the social and economic implications of current ecological issues as well as the basic biological concepts involved. It deals with the causes, effects and prevention of atmospheric and water pollution as well as with the disruption of ecosystems by changes in land use. The conflict of interests between conservation and exploitation is discussed, along with management techniques including the controversial method of culling to maintain diversity. The moral and aesthetic aspects of conservation and management are emphasised throughout, in addition to the scientific background of these techniques.

    In recent years, many controversies have taken place on the internet about the legitimacy of breast-feeding in full view of the public.The heart of these controversies can be summarized as follows:what is beautiful and what is reprehensi-ble?In this age of diverse ideologies, why is there so much tolerance about ugly things and yet so little tolerance, or even zero tolerance, for truly beautiful things?Focusing on the raging controversy about breast-feeding in upblic places and mak-ing reference to breast-feeding scene s in the history of Buddhist art and their underlying aestheitc ideas, this paper attempts to reflect on this phenomenon.%近年来,关于妇女在公共场所无遮盖哺乳是否具有正当性的争议,在互联网上可谓此伏彼起。这一争论的实质在于:什么是美的?什么是不美的?在这个思想观念日益多元的时代,为什么人们有时候能够对丑陋的事物表现出极大的宽容,却对某些真正美好的事物如此苛责,甚至是“零容忍”?由此围绕当代社会关于公共场所哺乳问题的争论,结合宗教艺术史上的诸多艺术表现及其背后的审美观念进行反思。

  11. Phytotoxins: environmental micropollutants of concern?

    Science.gov (United States)

    Bucheli, Thomas D

    2014-11-18

    Natural toxins such as mycotoxins or phytotoxins (bioactive compounds from fungi and plants, respectively) have been widely studied in food and feed, where they are stated to out-compete synthetic chemicals in their overall human and animal toxicological risk. A similar perception and awareness is yet largely missing for environmental safety. This article attempts to raise concern in this regard, by providing (circumstantial) evidence that phytotoxins in particular can be emitted into the environment, where they may contribute to the complex mixture of organic micropollutants. Exposures can be orders-of-magnitude higher in anthropogenically managed/affected (agro-)ecosystems than in the pristine environment.

  12. Increased (18)F-fluorodeoxyglucose uptake in benign, nonphysiologic lesions found on whole-body positron emission tomography/computed tomography (PET/CT): accumulated data from four years of experience with PET/CT.

    The use of (18)F-fluorodeoxyglucose positron emission tomography ((18)F-FDG-PET) in the field of oncology is rapidly evolving; however, (18)F-FDG is not tumor specific. Aside from physiological uptake (18)F-FDG also may accumulate in benign processes. Knowledge of these (18)F-FDG-avid nonmalignant lesions is essential for accurate PET interpretation in oncologic patients to avoid a false-positive interpretation. Through the systematic review of the reports of PET/computed tomography (CT) studies performed in oncologic patients during a 6-month period, we found benign nonphysiological uptake of (18)F-FDG in more than 25% of studies. In half of these, (18)F-FDG uptake was moderate or marked in intensity, similar to that of malignant sites. A total of 73% of benign lesions were inflammatory in nature, with post-traumatic bone and soft-tissue abnormalities (including iatrogenic injury) and benign tumors accounting for the remainder. The differentiation of benign from malignant uptake of (18)F-FDG on PET alone may be particularly challenging as a result of the low anatomical resolution of PET and paucity of anatomical landmarks. Fusion imaging, namely PET/CT, has been shown to improve not only the sensitivity of PET interpretation but also its specificity. Aside from better anatomical localization of lesions on PET/CT, morphological characterization of lesions on CT often may improve the diagnostic accuracy of nonspecific (18)F-FDG uptake. Correlation with CT on fused PET/CT data may obviate the need for further evaluation or biopsy in more than one-third of scintigraphic equivocal lesions. Familiarity with (18)F-FDG-avid nonmalignant lesions also may extend the use of (18)F-FDG-PET imaging beyond the field of oncology. We have tabulated our experience with benign entities associated with increased (18)F-FDG uptake on whole-body PET/CT from 12,000 whole-body (18)F-FDG-PET/CT studies performed during a 4-year period.

    2013-06-01

    Full Text Available The aim of this study was to determine the prevalence, characteristics, and factors related to feeding problems among normal children, and the differences in feeding practices between those with and without feeding problems. Caregivers of 402 healthy children aged between one and four years of age were interviewed by pediatricians involved in the research. Data included the child’s medical history, food intake within a day, and feeding behaviors and practices. Parental socio-economic and demographic information, as well as information on parental education and occupation, and their concerns about feeding their children, was collected. Physical examination and anthropometric measurements were taken. The percentage of children identified as having feeding problems was 26.9%. The first child of a family had an increased risk of having feeding problems [P=0.032, odds ratio 1.68, 95% confidence interval (95%CI 1.04-2.71]. Children with feeding problems were fed less frequently, were less likely to be fed at their own table or at the family table, and had mealtimes longer than 30 min when compared with children without feeding problems (P=0.015, 0.004 and 0.025, respectively. The results highlight that feeding problems in normally developing children are common. During consultations about feeding issues, pediatricians should focus on families with a first child. Topics such as frequency of meals per day, duration of meal-times, and appropriate places for feeding should be discussed.

    The pathophysiology and fundamental etiologic mechanism of inflammatory bowel disease (IBD) is not well understood even though therapeutic regimens and drugs are rapidly evolutionary. IBD has complicated connections with genetic, immunologic, gut microbial, environmental, and nutritional factors. It is not clearly well known to the physicians how to feed, what nutrients are more helpful, and what food to be avoided. This review discusses the issues of growth and important nutritional concerns in the management of IBD in childhood. PMID:27462352

    McComas, Katherine A; Besley, John C

    2011-11-01

    Research suggests that fairness perceptions matter to people who are asked to evaluate the acceptability of risks or risk management. Two separate national random surveys (n = 305 and n = 529) addressed Americans' concerns about and acceptance of nanotechnology risk management in the context of the degree to which they view scientists and risk managers as fair. The first survey investigated general views about scientists across four proposed dimensions of fairness (distributional, procedural, interpersonal, and informational). The results show that respondents who believe that the outcomes of scientific research tend to result in unequal benefits (distributional fairness) and that the procedures meant to protect the public from scientific research are biased (procedural fairness) were more concerned about nanotechnology. Believing scientists would treat them with respect (interpersonal fairness) and ensure access to information (informational fairness) were not significant predictors of concern. The second study also looked at these four dimensions of fairness but focused on perceptions of risk managers working for government, universities, and major companies. In addition to concern, it also examined acceptance of nanotechnology risk management. Study 2 results were similar to those of study 1 for concern; however, only perceived informational fairness consistently predicted acceptance of nanotechnology risk management. Overall, the study points to the value of considering fairness perceptions in the study of public perceptions of nanotechnology. © 2011 Society for Risk Analysis.

By probability we can see the possible realization of an act or event under certain conditions. Uncertainty is caused by emotional status of the decision maker due to more subjective factors or to the knowledge to achieve an objective. Risk is a combination of the two elements characterized by a possible description of probabilities under insecurity uncertainty conditions.

    In China, there is an old saying:food is the first necessity of humans. The main concern of the Chinese used to be the security of the food supply rather than the safety of the food itself. However,after a long time fighting food shortages,China became self-sufficient in food in 1995. At this time, the country began for the first time to regulate food safety. Yet China has still not established a legal systern efficient in ensuring this safety. Many problems are rooted in the administration regime and China's priority of economic development.

    Martin Heidegger's thought-provoking essay "The Question Concerning Technology" (1977a) placed technology at the heart of philosophy. Heidegger tried to show that the essence of technology provokes humans to think about the world in a very dangerous way. Yet if we follow Heidegger's analysis......, by doing so, we will in the end realize two important things. First, that Heidegger's declaration of the end of philosophy in fact also means the end of anything we can meaningfully call thinking. Second, that Heidegger's own thinking is completely different from his own ideal of thinking. Our question...

  12. Mothers who formula feed: their practices, support needs and factors influencing their Infant feeding decision

    Tarrant, R C

    2013-01-01

    The majority of mothers in Ireland provide formula milk to their infants during the initial weeks postpartum; however, data are lacking on their formula feeding practices and support needs. This prospective Dublin-based observational study, which included 450 eligible mother-term infant pairs recruited and followed up to 6 months postpartum, aimed to advance our understanding of maternal formula feeding practices, their reasons for deciding to formula feed, sources of feeding information and perceived support needs; insights into infant formula milk consumption patterns in relation to current feeding guidelines are also provided. In summary, the vast majority of infants at 6 weeks were provided with formula milk (n = 368; 81.8%). Positive maternal perceptions of formula feeding were among the most frequently reported reasons underlying mothers’ decision to formula feed (e.g. convenience, 17.3%). Potential public health concerns over the large formula milk volumes consumed by infants (mean 205ml\\/kilogram\\/day) relative to infant feeding guidelines (150ml\\/kilogram\\/day) were raised from this study. Some mothers continue to add solid foods to infant bottle feeds at 6 weeks (3.8%) and 6 months (6%), a non-recommended feeding practice posing a choking risk for infants. Crucially, this study highlights the need to provide greater support and information to mothers who decide to formula feed postpartum including practical information on sterilisation and formula reconstitution. While breastfeeding promotion and research continues to be a public health priority in Ireland, addressing the support and information needs of mothers who formula feed, an underrepresented and understudied population in the literature, also needs to be considered to ensure optimal health and safety for their infants.

  17. Is gastric sham feeding really sham feeding?

    Science.gov (United States)

    Sclafani, A; Nissenbaum, J W

    1985-03-01

    Rats were fitted with gastric cannulas, food deprived, and allowed to drink a sugar solution that drained out of the opened cannula; i.e., the rats sham-fed. Although this procedure is thought to prevent absorption of ingested food, it was found that the sham feeding of a 32% glucose or sucrose solution significantly elevated blood glucose levels. The addition of acarbose, a drug that inhibits the digestion of sucrose, to the 32% sucrose solution blocked the blood glucose rise, as did closing the pylorus with an inflatable pyloric cuff. Neither the drug nor the cuff, however, reduced the amount of sucrose solution consumed. These findings indicate that gastric sham feeding does not necessarily prevent the digestion and absorption of food, although absorption is not essential for the appearance of a vigorous sham-feeding response. Nevertheless the possibility that neural or hormonal feedback from the stomach contributes to the sham-feeding response cannot be excluded, and until this issue is resolved the results of gastric sham-feeding studies should be interpreted with caution.

  18. Complex Feeding Decisions

    Directory of Open Access Journals (Sweden)

    Anna Miles PhD

    2016-08-01

    Full Text Available Objective: Where swallowing difficulties are chronic or progressive, or a patient is palliative, tube feeding is often not deemed appropriate. Instead, patients continue to eat and drink despite the risks of pneumonia and death. There is currently little evidence to guide clinical practice in this field often termed “risk feeding.” This qualitative study investigated staff, patient, and family member perceptions of risk feeding practices in one New Zealand hospital. Method: Twenty-nine staff members and six patients and/or their family were interviewed. Results: Thematic analysis revealed four global themes: supporting practice, communication, complexity of feeding decisions, and patient and family-centered care. Staff described limited education and organizational policy around risk feeding decisions. Communication was considered a major factor in the success. Conclusion: Feeding decisions are complex in the hospital environment. The themes identified in this study provide a foundation for hospital guideline development and implementation.

    Addressing overeating is essential to obesity treatment and prevention. The objectives of this study were to investigate maternal concern for child overeating, to identify associated participant characteristics and to determine if concern for child overeating is associated with maternal feeding practices. Low-income mothers (N=289) of children (mean age 70.8months) participated in a semi-structured interview. Themes of maternal concern for child overeating were identified and a coding scheme was reliably applied. Maternal feeding practices were measured by questionnaire and videotaped eating interactions. Logistic regressions were used to test the associations of participant characteristics with the presence of each theme, and bivariate analyses were used to test the associations of the presence of each theme with feeding practices. Three themes were identified: 1) mothers worry that their child does overeat, 2) mothers acknowledge that their child may overeat but indicate that it is not problematic because they manage their child's eating behavior, and 3) mothers acknowledge that their child may overeat but indicate that it is not problematic because of characteristics inherent to the child. Child obesity predicted the themes; mothers of obese and overweight children are more likely to be concerned about overeating. Themes were associated with lower levels of observed pressure to eat. Only Theme 2 was associated with greater restrictive feeding practices. Interventions that provide parents' practical, healthy ways to prevent child overeating may be helpful.

    Postpyloric feeding is an important and promising alternative to parenteral nutrition. The indications for this kind of feeding are increasing and include a variety of clinical conditions, such as gastroparesis, acute pancreatitis, gastric outlet stenosis, hyperemesis (including gravida), recurrent aspiration, tracheoesophageal fistula and stenosis in gastroenterostomy. This review discusses the differences between pre- and postpyloric feeding, indications and contraindications, advantages and disadvantages, and provides an overview of the techniques of placement of various postpyloric devices.

  3. Lead toxicity: Current concerns

    Energy Technology Data Exchange (ETDEWEB)

    Goyer, R.A. (Univ. of Western Ontario, London (Canada))

    1993-04-01

    Over the 20-year period since the first issue of Environmental Health Perspectives was published, there has been considerable progress in the understanding of the potential toxicity of exposure to lead. Many of these advances have been reviewed in published symposia, conferences, and review papers in EHP. This brief review identifies major advances as well as a number of current concerns that present opportunities for prevention and intervention strategies. The major scientific advance has been the demonstration that blood lead (PbB) levels of 10-15 micrograms/dL in newborn and very young infants result in cognitive and behavioral deficits. Further support for this observation is being obtained by prospective or longitudinal studies presently in progress. The mechanism(s) for the central nervous system effects of lead is unclear but involve lead interactions within calcium-mediated intracellular messenger systems and neurotransmission. Effects of low-level lead exposure on blood pressure, particularly in adult men, may be related to the effect of lead on calcium-mediated control of vascular smooth muscle contraction and on the renin-angiotensin system. Reproductive effects of lead have long been suspected, but low-level effects have not been well studied. Whether lead is a carcinogen or its association with renal adenocarcinoma is a consequence of cystic nephropathy is uncertain. Major risk factors for lead toxicity in children in the United States include nutrition, particularly deficiencies of essential metals, calcium, iron, and zinc, and housing and socioeconomic status. A goal for the year 2000 is to reduce prevalence of blood lead levels exceeding 15 micrograms/dL. 97 refs.

  4. Adolescent fertility: worldwide concerns.

    Science.gov (United States)

    Senderowitz, J; Paxman, J M

    1985-04-01

    There is growing concern over the adverse health, social, economic, and demographic effects of adolescent fertility. Morbidity and mortality rates ar significantly higher for teenage mothers and their infants, and early initiation of childbearing generally means truncated education, lower future family income, and larger completed family size. Adolescent fertility rates, which largely reflect marriage patterns, range from 4/1000 in Mauritania; in sub-Saharan Africa, virtually all rates are over 100. In most countries, adolescent fertility rates are declining due to rising age at marriage, increased educational and economic opportunities for young women, changes in social customs, increased use of contraception, and access to abortion. However, even if fertility rates were to decline dramatically among adolescent women in developing countries, their sheer numbers imply that their fertility will have a major impact on world population growth in the years ahead. The number of women in the world ages 15-19 years is expected to increase from 245 million in 1985 to over 320 million in the years 2020; 82% of these women live in developing countries. As a result of more and earlier premarital sexual activity, fostered by the lengthening gap between puberty and marriage, diminished parental and social controls, and increasing peer and media pressure to be sexually active, abortion and out-of-wedlock childbearing are increasing among teenagers in many developed and rapidly urbanizing developing countries. Laws and policies regarding sex education in the schools and access to family planning services by adolescents can either inhibit or support efforts to reduce adolescent fertility. Since contraceptive use is often sporadic and ineffective among adolescents, family planning services are crucial. Such programs should aim to reduce adolescents' dependence on abortion through preventive measures and increase awareness of the benefits of delayed sexual activity. Similarly, sex

  10. Urban Bird Feeding: Connecting People with Nature.

    Directory of Open Access Journals (Sweden)

    Daniel T C Cox

    Full Text Available At a time of unprecedented biodiversity loss, researchers are increasingly recognizing the broad range of benefits provided to humankind by nature. However, as people live more urbanized lifestyles there is a progressive disengagement with the natural world that diminishes these benefits and discourages positive environmental behaviour. The provision of food for garden birds is an increasing global phenomenon, and provides a readily accessible way for people to counter this trend. Yet despite its popularity, quite why people feed birds remains poorly understood. We explore three loosely defined motivations behind bird feeding: that it provides psychological benefits, is due to a concern about bird welfare, and/or is due to a more general orientation towards nature. We quantitatively surveyed households from urban towns in southern England to explore attitudes and actions towards garden bird feeding. Each household scored three Likert statements relating to each of the three motivations. We found that people who fed birds regularly felt more relaxed and connected to nature when they watched garden birds, and perceived that bird feeding is beneficial for bird welfare while investing time in minimising associated risks. Finally, feeding birds may be an expression of a wider orientation towards nature. Overall, we found that the feelings of being relaxed and connected to nature were the strongest drivers. As urban expansion continues both to threaten species conservation and to change peoples' relationship with the natural world, feeding birds may provide an important tool for engaging people with nature to the benefit of both people and conservation.

  14. Adolescent attitudes, beliefs, and concerns regarding breastfeeding.

    Science.gov (United States)

    Nelson, Antonia M

    2009-01-01

    To investigate the attitudes, beliefs, and concerns of pregnant and postpartum adolescents regarding breastfeeding. Audiotaped focus groups of low-income, largely minority pregnant and postpartum adolescents were conducted and transcripts analyzed using content analysis techniques. Major themes identified were in the area of beliefs, such as "They say" it's healthy, or "It hurts"; attitudes, such as breastfeeding is the mother's "choice" and "The baby comes first"; and concerns such as privacy, and "Breastfeeding leads to dependency." Adolescents can be encouraged to breastfeed, but require appropriate education beyond what they have heard from others. Myths such as pain during breastfeeding need to be addressed. Since teens want to learn but not be told what to do, active learning strategies such as guided Internet searches could be helpful to guide them into discovery of the benefits of breastfeeding. Since all the teens in this study felt that "the baby comes first," emphasizing the benefits of breastfeeding for the baby should predominate educational efforts. Concerns related to physical exposure while breastfeeding can be addressed antenatally through discussing creative strategies to maintain modesty. This study suggests that, in the postpartum hospital setting, adopting a sensitive, initially "hands-off' approach to supporting breastfeeding might be more well-accepted than tactile assistance, and that following the initial establishment of a milk supply, various levels of breastfeeding exclusivity should be considered as potentially acceptable infant feeding patterns.

    2000-10-01

    The aim of this study was to estimate the prevalence and severity of feeding and nutritional problems in children with neurological impairment within a defined geographical area. In a cross-sectional study, a validated questionnaire was sent to 377 parents of children (aged 4 to 13 years) on the Oxford Register of Early Childhood Impairments with oromotor dysfunction. The return rate was 72%. Of these, 93% had cerebral palsy; 47% were unable to walk; 78% had speech difficulty; and 28% continuous drooling of saliva. Gastrointestinal problems were commonly encountered: 59% were constipated; 22% had significant problems with vomiting, and 31% had suffered at least one chest infection in the previous 6 months. Feeding problems were prevalent: 89% needed help with feeding and 56% choked with food; 20% of parents described feeding as stressful and unenjoyable. Prolonged feeding times (3h/day) were reported by 28%. Only 8% of participants received caloric supplements and 8% were fed via gastrostomy tube. Even though 38% of respondents considered their child to be underweight, 64% of children had never had their feeding and nutrition assessed. The results highlight that feeding problems in children with neurological impairment are common and severe, causing parental concern. Many of these children would benefit from nutritional assessment and management as part of their overall care.

    MacDonald, A; Depondt, E; Evans, S; Daly, A; Hendriksz, C; Chakrapani A, A; Saudubray, J-M

    2006-01-01

    Breast feeding has proven benefits for many infants with inherited metabolic disorders (IMDs) but, with the exception of phenylketonuria, there are few reports in other conditions. A questionnaire, completed by dietitians and clinicians from 27 IMD centres from 15 countries (caring for a total of over 8000 patients with IMDs on diet) identified breast feeding experience in IMD. Successful, demand breast feeding (in combination with an infant amino acid formula free of precursor amino acids) was reported in 17 infants with MSUD, 14 with tyrosinaemia type I, and 5 with homocystinuria. Eighty-nine per cent were still breast fed at 16 weeks. Fewer infants with organic acidaemias were demand breast fed (7 with propionic acidaemia; 6 with methylmalonic acidaemia and 13 with isovaleric acidaemia) (usually preceded by complementary feeds of a protein-free infant formula or infant amino acid formula free of precursor amino acids). Only 12 infants with urea cycle disorders were given demand breast feeds, but this was unsuccessful beyond 8 days in CPS deficiency. Further work is needed in developing guidelines for feeding and for clinical and biochemical monitoring for breast-fed infants with IMDs.

    OBJECTIVE: All forms of commonly practiced enteral feeding techniques stimulate pancreatic secretion, and only intravenous feeding avoids it. In this study, we explored the possibility of more distal enteral infusions of tube feeds to see whether activation of the ileal brake mechanism can result...... in enteral feeding without pancreatic stimulation, with particular reference to trypsin, because the avoidance of trypsin stimulation may optimize enteral feeding in acute pancreatitis. METHODS: The pancreatic secretory responses to feeding were studied in 36 healthy volunteers by standard double......-lumen duodenal perfusion/aspiration techniques over 6 hours. Subjects were assigned to no feeding (n = 7), duodenal feeding with a polymeric diet (n = 7) or low-fat elemental diet (n = 6), mid-distal jejunal feeding (n = 11), or intravenous feeding (n = 5). All diets provided 40 kcal/kg ideal body weight/d and 1...

    In recent years, deep learning has achieved great success in many fields, ranging from voice recognition and image classification to computer vision. In this study we apply DBNs to concerned internet information in Chinese detecting problem, since there are inherent differences between English and Chinese. Contrastive divergence (CD) is employed in the DBNs to learn a multi-layer generative model from numerous unlabeled data. The features obtained by this model are used to initialize the feed-forward neural network, which can be fine-tuned with backpropagation. Experiment results indicate that, the model and training method we proposed can be used to detect the concerned internet information effectively and accurately.

    Since feeding behavior has a complex physiological background, in the physiology of feeding behavoir not only the mechanisms in the hypothalamus, but also input and output physiologic factors which stimulate and/or inhibit the central network for feeding and aversion behavior, must be considered. Normal feeding and aversion behavior are accomplished by a series of highly co-ordinated physiological functions involving various parts of the body, and humoral, hormonal, metabolic, and sensory and motor functions for feeding behavior must be well considered from a wider wiew point. For this purpose, morphological, biochemical, and neurophysiological extensive approaches to study the feeding behavior mechanisms are essentially important. In the present paper, neurophysiological network concerning feeding and aversion behavior was under discussion. Particularly, relations between input, central and output factors for these behaviors were considered. As an input factor, a role of the nerve impulses of the chorda tympani and lingual nerves was evaluated. As a central factor, involvement of the neurons in the cortical taste area was discussed, and response patterns of cortical taste neurons to negative and positive taste information was analyzed with regard to taste perception mechanisms. In addition, mechanisms in the posterior hypothalamus for the taste aversion behavior were explained through ablation and recording techniques in the rat; and the neuromuscular mechanisms of chewing, which complete the feeding behavior, were also discussed. Importance of such comprehensive systematic approach to proper understanding of feeding and aversion behaviors was emphasized.

  11. Enteral feeding pumps: efficacy, safety, and patient acceptability

    Full Text Available Helen White, Linsey King Nutrition and Dietetic Group, School of Health and Wellbeing, Faculty Health and Social Science, Leeds Metropolitan University, Leeds, United Kingdom Abstract: Enteral feeding is a long established practice across pediatric and adult populations, to enhance nutritional intake and prevent malnutrition. Despite recognition of the importance of nutrition within the modern health agenda, evaluation of the efficacy of how such feeds are delivered is more limited. The accuracy, safety, and consistency with which enteral feed pump systems dispense nutritional formulae are important determinants of their use and acceptability. Enteral feed pump safety has received increased interest in recent years as enteral pumps are used across hospital and home settings. Four areas of enteral feed pump safety have emerged: the consistent and accurate delivery of formula; the minimization of errors associated with tube misconnection; the impact of continuous feed delivery itself (via an enteral feed pump; and the chemical composition of the casing used in enteral feed pump manufacture. The daily use of pumps in delivery of enteral feeds in a home setting predominantly falls to the hands of parents and caregivers. Their understanding of the use and function of their pump is necessary to ensure appropriate, safe, and accurate delivery of enteral nutrition; their experience with this is important in informing clinicians and manufacturers of the emerging needs and requirements of this diverse patient population. The review highlights current practice and areas of concern and establishes our current knowledge in this field. Keywords: nutrition, perceptions, experience

    Some of the major obstacles to the practice of breast feeding among tribal communities are ignorance and taboos concerning food and feeding. 100 nursing mothers in 12 tribal villages were observed in a study of infant feeding practices. Information about the existing feeding practices was collected; in addition, the study researched attitudes and values concerning the topic of infant feeding. 95% of the women breast fed their babies. Many of the mothers (42%) understood that supplementary foods could be given by the end of the 1st year. Although breast feeding practice was high, the majority of the women (83%) did not believe that it was necessary to make changes in their diets or work styles during the lactating period. 66% of the women did not comprehend how lactation performance could decrease. Only 17% of the mothers took good care during the period of lactation. Education programs should be designed to encourage a unique work and dietary routine for mothers who are breast feeding.

    Pakistan is both a country of origin and destination as far as women trafficking is concerned. Poverty, gender discrimination, lack of education, and ignorance about legal rights are some of the underlying causes. Available data suggest several areas of concern, like, for instance: direct health effects, maladaptive coping leading to the use of illicit drugs, and inaccessibility to healthcare facilities. Therefore, numerous interventions would be required at three levels: the prevention of trafficking, the protection of victims and the prosecution of the traffickers.

    The impacts of biotechnology are found in nearly all sectors of society from health care and food products to environmental issues and energy sources. Despite the significance of biotechnology within the sciences, it has not become a prominent trend in science education. In this study, we seek to more fully identify biology teachers' concerns about biotechnology instruction and their reported practices. Consistent with the Stages of Concern framework as modified by Hord et al., we investigated teachers' awareness, informational, personal, management, consequences, collaboration, and refocusing concerns about biotechnology teaching by employing a qualitative design that allowed for the emergence of teachers' ideas. Twenty high school life science teachers attending a biotechnology institute were interviewed using an interview protocol specifically designed to target various Stages of Concern. Although the Stages of Concern framework guided the development of interview questions in order to target a wide range of concerns, data analysis employed a grounded theory approach wherein patterns emerged from teachers' own words and were constantly compared with each other to generate larger themes. Our results have potential to provide guidance for professional development providers and curriculum developers committed to supporting initial implementation of biotechnology education. Recommendations include supporting teacher development of biotechnology content knowledge; promoting strategies for obtaining, storing and managing biotechnology equipment and materials; providing opportunities for peer teaching as a means of building teacher confidence; and highlighting career opportunities in biotechnology and the intersections of biotechnology and everyday life.

    Progress, which is brought by new advances in modern molecular biology, allowed interference in the genome of live organisms and gene manipulation. Introducing new genes to the recipient organism enables to give them new features, absent before. Continuous increase in the area of the biotech crops triggers continuous discussion about safety of genetically modified (GM) crops, including food and feed derived from them. Important issue connected with cultivation of genetically modified crops is a horizontal gene transfer and a bacterial antibiotic resistance. Discussion about safety of GM crops concerns also food allergies caused by eating genetically modified food. The problem of genetic modifications of GM crops used for livestock feeding is widely discussed, taking into account Polish feed law.

    Turck, D

    2010-12-01

    Complementary feeding, which embraces all solid and liquid foods other than breast milk or infant formula, is strongly influenced by cultural, familial and economic factors. For many times, there was a strong taboo on the use of colostrum ("the white blood") during the first week after delivery, sometimes even the first month. Therefore, the newborn baby received complementary foods as gruel, or panada. However, in the Greek civilization, wet nurses were asked by contract to breastfeed exclusively for the first 6 months and to start complementary feeding thereafter. From the sixteenth century onwards, many writers deplored the practice of giving gruel and panada during the first six months before the teeth erupted. In 1921, a Swedish pediatrician, Jundell, reported for the first time that starting complementary feeding at 6 months of age was associated with a better growth and resistance to infections. The recommendation of the World Health Organization to start complementary feeding after a 6-month period of exclusive breastfeeding is often in contradiction with the habits of the populations to propose very early other food sources than breast milk.

    Full Text Available Over the past 40 years, obesity rates in the United States have grown significantly; these rates have not grown uniformly across the United States (18 of the 20 counties with the highest obesity rates are located in the South. Obesity increases cardiovascular disease risk factors and new research has highlighted the negative psychological effects of obesity, known as weight stigma, including decreased selfcontrol resources, over eating, and exercise avoidance. The primary objective of this study was to determine if weight stigma concerns varied regionally and if social behaviors influenced this variation. In two studies, we collected cross-sectional data from participants in the United States including height and weight, weight stigma concerns, and perception of friends’ preoccupation with weight and dieting. We also collected each participant’s home zip code which was used to locate local obesity rate. We established differences in the relationship between body mass index and weight stigma concerns by local county obesity rate and showed that perceived friend preoccupation with weight and dieting mediated this relationship for individuals in low and medium obesity rate counties. For individuals living in United States counties with lower levels of obesity, increases in personal body mass index leads to increased weight stigma concerns due to an increase in perceived friend preoccupation with weight and dieting. These results indicate that relationships between body mass index, weight stigma concerns, and social networks vary significantly for subpopulations throughout the United States.

    Full Text Available Regardless of habitat or time of day, cattle egrets feeding independently of hosts generally occurring larger groups than those feeding in close association with ungulates. The average group size of three individuals feeding in association with hosts stays remarkably constant with regard to divergent situations. Based on the type of habitat and the grazing speed of the host concerned, cattle egrets achieve the highest feeding success (number of prey items with the least energy inputs (number of paces in association with cattle, and to a lesser extent with the closely related buffalo. Compared to solitary birds, cattle egrets feeding in groups experience without exceptional higher feeding success. Results of feeding experiments, as well as the exceptional occurrence of so-called feeding lines, confirm the phenomenon that the feeding success of cattle egrets correlates closely with the size of the feeding group.

    2017-04-01

    Full Text Available Effective utilization of available feed resources is the key for economical livestock rearing. Complete feed system is one of the latest developments to exploit the potential of animal feed resources in the best possible way. The complete feed is a quantitative mixture of all dietary ingredients, blended thoroughly to prevent separation and selection, fed as a sole source of nutrients except water and is formulated in a desired proportion to meet the specific nutrient requirements. The concentrate and roughage levels may vary according to the nutrient requirement of ruminants for different production purposes. The complete feed with the use of fibrous crop residue is a noble way to increase the voluntary feed intake and thus animal's production performance. In this system of feeding, the ruminant animals have continuous free choice availability of uniform feed mixture, resulting in more uniform load on the rumen and less fluctuation in release of ammonia which supports more efficient utilization of ruminal non-protein nitrogen. Feeding complete diet stabilizes ruminal fermentation, thereby improves nutrient utilization. This feeding system allows expanded use of agro-industrial byproducts, crop residues and nonconventional feeds in ruminant ration for maximizing production and minimizing feeding cost, thus being increasingly appreciated. However, to extend the concept extensively to the field and make this technology successful and viable for farmers, more efforts are needed to be taken.

Results showed that 44.4% of SJSU and 80.4% of PUC-Campinas .students had been breast-fed (p=0.01. Although students intended to breast-feed, both groups had a negative attitude toward breast-feeding in public: SJSU students (56.8% felt social pressures to not breast=feed in public, and PUC-Campinas students (54.3% expressed personal constraint. SJSU students emphasized convenience, and PUC-Campinas students mentioned, immunological factors as advantages of breast-feeding. PUC-Campinas students considered protection as an advantage of formula, feeding. Concerning causal factors for breast feeding failure, SJSU students cited negative social pressure and biological problems, and PUC-Campinas students mentioned, lack of information. In conclusion, it is necessary to improve the curricula, if we expect future nutrition professionals to have adequate knowledge to promote and choose breast feeding successfully.

    The objectives of this study were to determine the effect of feed presentation on meal frequency and duration, as well as diurnal feeding patterns of dairy calves, and to assess any longer-term differences in feeding patterns resulting from previous experience. Twenty Holstein bull calves were exposed from wk 1 to 8 of life to 1 of 2 feed presentation treatments: concentrate and chopped grass hay (spent more time feeding than calves fed COM (56.7 vs. 46.8 min/d). In wk 8, calves fed MIX spent more time feeding (174.0 vs. 139.1 min/d) and had a lower rate of intake (11.5 vs. 14.7 g/min) compared with calves fed COM. Meal frequency was similar between treatments (12.2 meals/d). Diurnal feeding patterns in wk 8 were also affected by feed presentation, with calves fed MIX spending less time feeding at time of feed delivery and more time feeding throughout the rest of the daylight hours than calves fed COM. Diurnal feeding patterns of hay and concentrate in wk 8 differed for calves fed COM, with more time spent consuming hay at time of feed delivery and less time spent consuming hay throughout the rest of the day. Once calves previously fed COM were transitioned to the MIX diet in wk 9, meal frequency, meal duration, and diurnal feeding patterns were similar between treatments: both treatments spent similar amounts of time feeding (173.9 min/d) and had similar peaks in feeding activity at time of feed delivery, sunrise, and sunset. Provision of hay and concentrate to young calves as a mixed ration, compared with separate components, increases time spent feeding and results in more evenly distributed diurnal feeding patterns. However, differences in feeding patterns resulting from feed presentation did not persist after 8 wk of age, when all calves were fed a mixed ration.

    Full Text Available Ethoxyquin (EQ, 6-ethoxy-1,2-dihydro-2,2,4-trimethylquinoline is widely used in animal feed in order to protect it against lipid peroxidation. EQ cannot be used in any food for human consumption (except spices, e.g., chili, but it can pass from feed to farmed fish, poultry, and eggs, so human beings can be exposed to this antioxidant. The manufacturer Monsanto Company (USA performed a series of tests on ethoxyquin which showed its safety. Nevertheless, some harmful effects in animals and people occupationally exposed to it were observed in 1980’s which resulted in the new studies undertaken to reevaluate its toxicity. Here, we present the characteristics of the compound and results of the research, concerning, for example, products of its metabolism and oxidation or searching for new antioxidants on the EQ backbone.

    Food security is an important factor in non-traditional security concerns. Does China have food shortage concerns? How should China guarantee its food security? Beijing Review reporter Feng Jianhua discusses these issues with Professor Li Chenggui, head of the Center for Rural Policy under the Chinese Academy of Social Sciences, and Yang Shaopin, Director of the Bureau of State Farms and Land Reclamation under the Ministry of Agriculture.

  7. Concerning technology: thinking with Heidegger.

    In human lives, technology holds sway in mundane and extraordinary ways, such as in the ways we work, entertain, transport, and feed ourselves, and importantly in the ways we encounter and manage health, disease, illness, and death. A significant area of Heidegger's later work is questioning technology. Unlike many current inquiries that centre on contemporary technology's function, utility, and positive transformations, Heidegger offers a radical way of thinking about technology through developing an inquiry that uncovers technology's essence of revealing. In this article, Heidegger's thinking about technological modes of revealing in regard to bodies, health, and illness is explored. In Heidegger's view, the ordered revealing of modern technology has overshadowed other modes of revealing. This article highlights how remembering concealment and unconcealment in its many modes can be relevant to nurses and others involved in health care. Through tracing Heidegger's thinking about technology, a more critical approach to the effects and outcomes of modern technologies within health care systems can be generated.

    Since the announcement of the ban on the use of antibiotics as antimicrobial growth promoters in the feed of pigs in 2006 the investigation towards alternative feed additives has augmented considerably. Although fermented liquid feed is not an additive, but a feeding strategy, the experimental work examining its possible advantages also saw a rise. The use of fermented liquid feed (FLF) has two main advantages, namely that the simultaneous provision of feed and water may result in an alleviation of the transition from the sow milk to solid feed and may also reduce the time spent to find both sources of nutrients, and secondly, that offering FLF with a low pH may strengthen the potential of the stomach as a first line of defence against possible pathogenic infections. Because of these two advantages, FLF is often stated as an ideal feed for weaned piglets. The results obtained so far are rather variable, but in general they show a better body weight gain and worse feed/gain ratio for the piglets. However, for growing-finishing pigs on average a better feed/gain ratio is found compared to pigs fed dry feed. This better performance is mostly associated with less harmful microbiota and better gut morphology. This review provides an overview of the current knowledge of FLF for pigs,dealing with the FLF itself as well as its effect on the gastrointestinal tract and animal performance.

    1985-01-01

    The transition period from endogenous to exogenous feeding by larval herring was investigated in the laboratory for four herring stocks in order to evaluate the chances of survival at the time of fiest feeding. Observations on larval activity, feeding and growth were related to amount of yolk......, visual experience with potential prey organisms prior to first feeding and prey density. Herring larvae did not initiate exogenous feeding until around the time of yolk resorption. The timing of first feeding was not influenced by prior exposure to potential prey organisms during the yolk sac stage....... In the light of these observations, the ecological significance of the yolk sac stage is discussed. Initiation of exogenous feeding was delayed by 1-4 days at a low (7.5 nauplii .cntdot. l-1) compared to a high (120 nauplii .cntdot. l-1) prey density, but even at prey densities corresponding to the lower end...

    In the current investigation, we evaluated a method for increasing self-feeding with 3 children with a history of food refusal. The children never (2 children) or rarely (1 child) self-fed bites of food when the choice was between self-feeding and escape from eating. When the choice was between self-feeding 1 bite of food or being fed an identical bite of food, self-feeding was low (2 children) or variable (1 child). Levels of self-feeding increased for 2 children when the choice was between self-feeding 1 bite of food or being fed multiple bites of the same food. For the 3rd child, self-feeding increased when the choice was between self-feeding 1 bite of food or being fed multiple bites of a less preferred food. The results showed that altering the contingencies associated with being fed increased the probability of self-feeding, but the specific manipulations that produced self-feeding were unique to each child.

  11. Accountable care organizations: legal concerns.

    Sanbar, S Sandy

    2011-01-01

    The Accountable Care Organizations (ACOs) shared savings program has serious concerns about anti-trust and anti-fraud laws. Additionally, ACOs present several other legal concerns relating to the duties and responsibilities of the physician-hospital partnership. The federal regulations hold physicians who participate in the ACO shared savings program to the highest standards of care without offering them protection from liability. The structure and procedures required of ACOs may be detrimental and may significantly impact the liability of its contracting physicians. Therefore, it behooves physicians to obtain legal advice regarding one's estate planning and legal asset protection or wealth management techniques, and to thoroughly review the agreement with one's attorney before signing a contract with an ACO.

    The realization of tractor bundles as associated bundles in conformal geometry is studied. It is shown that different natural choices of principal bundle with normal Cartan connection corresponding to a given conformal manifold can give rise to topologically distinct associated tractor bundles for the same inducing representation. Consequences for homogeneous models and conformal holonomy are described. A careful presentation is made of background material concerning standard tractor bundles and equivalence between parabolic geometries and underlying structures.

    In this paper we discuss normal functions concerning shared values. We obtain the follow result. Let F be a family of meromorphic functions in the unit disc △, and a be a nonzero finite complex number. If for any f ∈ F, the zeros of f are of multiplicity, f and f' share a, then there exists a positive number M such that for any f ∈ F, (1 -|z|~2)(|f'(z)|)/(1+|f(z)|~2)≤ M.

  18. Bridgman's concern (shock compression science)

    Science.gov (United States)

    Graham, R. A.

    1994-07-01

    In 1956 P. W. Bridgman published a letter to the editor in the Journal of Applied Physics reporting results of electrical resistance measurements on iron under static high pressure. The work was undertaken to verify the existence of a polymorphic phase transition at 130 kbar (13 GPa) reported in the same journal and year by the Los Alamos authors, Bancroft, Peterson, and Minshall for high pressure, shock-compression loading. In his letter, Bridgman reported that he failed to find any evidence for the transition. Further, he raised some fundamental concerns as to the state of knowledge of shock-compression processes in solids. Later it was determined that Bridgman's static pressure scale was in error, and the shock observations became the basis for calibration of pressure values in static high pressure apparatuses. In spite of the error in pressure scales, Bridgman's concerns on descriptions of shock-compression processes were perceptive and have provided the basis for subsequent fundamental studies of shock-compressed solids. The present paper, written in response to receipt of the 1993 American Physical Society Shock-Compression Science Award, provides a brief contemporary assessment of those shock-compression issues which were the basis of Bridgman's 1956 concerns.

  19. Financial equilibrium with career concerns

    Full Text Available What are the equilibrium features of a financial market where a sizeable proportion of traders face reputational concerns? This question is central to our understanding of financial markets, which are increasingly dominated by institutional investors. We construct a model of delegated portfolio management that captures key features of the US mutual fund industry and embed it in an asset pricing framework. We thus provide a formal model of financial equilibrium with career concerned agents. Fund managers differ in their ability to understand market fundamentals, and in every period investors choose a fund. In equilibrium, the presence of career concerns induces uninformed fund managers to churn, i.e., to engage in trading even when they face a negative expected return. Churners act as noise traders and enhance the level of trading volume. The equilibrium relationship between fund return and net fund flows displays a skewed shape that is consistent with stylized facts. The robustness of our core results is probed from several angles.

  5. Pap, gruel, and panada: early approaches to artificial infant feeding.

    Science.gov (United States)

    Obladen, Michael

    2014-01-01

    This paper collects information on artificial infant feeding published before 1860, the year when commercial formula became available. We have extensive artifactual evidence of thousands of feeding vessels since the Bronze Age. Special museum collections can be found in London, Paris, Cologne, Fécamp, Toronto, New Mexico, and elsewhere. The literature on the use of animal milk for infant feeding begins with Soranus in the 2nd century CE. Literature evidence from the very first printed books in the 15th century proves that physicians, surgeons, midwives, and the laity were aware of the opportunities and risks of artificial infant feeding. Most 17th to 19th century books on infant care contained detailed recipes for one or several of the following infant foods: pap, a semisolid food made of flour or bread crumbs cooked in water with or without milk; gruel, a thin porridge resulting from boiling cereal in water or milk, and panada, a preparation of various cereals or bread cooked in broth. During the 18th century, the published opinion on artificial feeding evolved from health concerns to a moral ideology. This view ignored the social and economic pressures which forced many mothers to forego or shorten breast-feeding. Bottle-feeding has been common practice throughout history.

    1993-06-01

    The Advanced Liquid Feed Experiment (ALFE) is a Hitchhiker experiment flown on board the Shuttle of STS-39 as part of the Space Test Payload-1 (STP-1). The purpose of ALFE is to evaluate new propellant management components and operations under the low gravity flight environment of the Space Shuttle for eventual use in an advanced spacecraft feed system. These components and operations include an electronic pressure regulator, an ultrasonic flowmeter, an ultrasonic point sensor gage, and on-orbit refill of an auxiliary propellant tank. The tests are performed with two transparent tanks with dyed Freon 113, observed by a camera and controlled by ground commands and an on-board computer. Results show that the electronic pressure regulator provides smooth pressure ramp-up, sustained pressure control, and the flexibility to change pressure settings in flight. The ultrasonic flowmeter accurately measures flow and detects gas ingestion. The ultrasonic point sensors function well in space, but not as a gage during sustained low-gravity conditions, as they, like other point gages, are subject to the uncertainties of propellant geometry in a given tank. Propellant transfer operations can be performed with liquid-free ullage equalization at a 20 percent fill level, gas-free liquid transfer from 20-65 percent fill level, minimal slosh, and can be automated.

  8. Oxytocin, feeding and satiety

    Directory of Open Access Journals (Sweden)

    Nancy eSabatier

    2013-03-01

    Full Text Available Oxytocin neurones have a physiological role in food intake and energy balance. Central administration of oxytocin is powerfully anorexigenic, reducing food intake and meal duration. The central mechanisms underlying this effect of oxytocin have become better understood in the past few years. Parvocellular neurones of the paraventricular nucleus project to the caudal brainstem to regulate feeding via autonomic functions including the gastrointestinal vago-vagal reflex. In contrast, magnocellular neurones of the supraoptic and paraventricular nuclei release oxytocin from their dendrites to diffuse to distant hypothalamic targets involved in satiety.The ventromedial hypothalamus, for example, expresses a high density of oxytocin receptors but does not contain detectable oxytocin nerve fibres. Magnocellular neurones represent targets for the anorexigenic neuropeptide α-melanocyte stimulating hormone. . In addition to homeostatic control, oxytocin may also have a role in reward-related feeding. Evidence suggests that oxytocin can selectively suppress sugar intake and that it may have a role in limiting the intake of palatable food by inhibiting the reward pathway.

    Full Text Available Background: Parents’ perception of whether children are overweight can influence parenting practices. The purpose of this study was to examine parental perception of and concern for child weight in relation to parenting practices. Methods: A cross-sectional study of parents (n=75 with pre-school age children. Parents completed the Child Feeding Questionnaire and Parenting Strategies for Obesogenic Behaviors Questionnaire. Perception (overweight vs. not overweight and concern (concerned vs. not concerned of child weight were examined in relation to individual strategies (Chi-square and feeding practices (independent t-tests. Findings were confirmed in analyses adjusted for child race, sex, and weight status. Results: Five percent of parents perceived their child as overweight; 61.3% of parents were concerned about their child becoming overweight; 36% of children were overweight. Parents who perceived their child as overweight agreed their child should always eat all of the food on his/her plate (75%, p=0.031. Concerned parents made sure their child did not eat too many sweets (89%, p=0.005, high fat foods (78%, p=0.001, or favorite foods (59%, p=0.009; kept some foods out of reach (76%, p=0.014; kept track of sweets eaten (87%, p=0.012 and television watched (83%, p=0.046. Parents with concern used restrictive feeding practices (3.6% vs. 2.9%, p=0.003 and had children with a higher BMI percentile (75.0 vs. 51.0, p=0.001. Adjustment for multiple analyses was more conservative (p≤0.003. Conclusions: Parents’ concern as to whether their child is overweight was associated with overall restrictive feeding practices and children with higher body mass. Individual strategies employed by parents with a perception of or concern for overweightness included restriction, monitoring, and pressure to eat.

    Oplatowska-Stachowiak, Michalina; Elliott, Christopher T

    2017-02-11

    Food colors are added to different types of commodities to increase their visual attractiveness or to compensate for natural color variations. The use of these additives is strictly regulated in the European Union, the United States, and many other countries worldwide. There is a growing concern about the safety of some commonly used legal food colorants and there is a trend to replace the synthetic forms with natural products. Additionally, a number of dyes with known or suspected genotoxic or carcinogenic properties have been shown to be added illegally to foods. Robust monitoring programs based on reliable detection methods are required to assure the food is free from harmful colors. The aim of this review is to present an up to date status of the various concerns arising from use of color additives in food. The most important food safety concerns in the field of food colors are lack of uniform regulation concerning legal food colors worldwide, possible link of artificial colors to hyperactive behavior, replacement of synthetic colors with natural ones, and the presence of harmful illegal dyes-both known but also new, emerging ones in food. The legal status of food color additives in the EU, United States, and worldwide is summarized. The reported negative health effects of both legal and illegal colors are presented. The European Rapid Alert System for Food and Feed notifications and US import alerts concerning food colors are analyzed and trends in fraudulent use of color additives identified. The detection methods for synthetic colors are also reviewed.

    Murray Code

    2012-05-01

    Full Text Available A consumer society that has embraced global capitalism while striving to preserve all the comforts and conveniences provided by technoscience is arguably fatally ill. Much support for this gloomy diagnosis is provided by, among others, Hannah Arendt, Northrop Frye, and Friedrich Nietzsche. Their reflections on the health of a human culture point up the urgency of the need to rethink the idea of good reasoning that predominates in the West. However, they also indicate that a healthier, more life-enhancing conception of good reasoning will arise only when a concern for justice and wisdom displaces the traditional ideals of pure and certain knowledge or eternal truths. To this end, Nietzsche recommends that philosophy ought now to concentrate on producing `cultural physicians' who would strive to fashion a philosophy of concern. This type of philosophical therapist requires a radically nonmodern approach to philosophy that must pivot on a vitalistic metaphysics capable of overcoming pervasive nihilistic ideologies which illustrate a globally spreading mythology of unconcern. Hence an effective and lasting cultural therapy will depend on the emergence of a general will/desire to broaden the conception of good reasoning beyond the narrow perspectives established by modern science. And this will depend in turn on the education of future educators who stress above all the importance of cultivating the mythopoeic imaginations of the young.

    2002-06-01

    Recent advances in agricultural biotechnology have highlighted the need for experimental evidence and sound scientific judgment to assess the benefits and risks to society. Nutrition scientists and other animal biologists need a balanced understanding of the issues to participate in this assessment. To date most modifications to crop plants have benefited producers. Crops have been engineered to decrease pesticide and herbicide usage, protect against stressors, enhance yields and extend shelf life. Beyond the environmental benefits of decreased pesticide and herbicide application, consumers stand to benefit by development of food crops with increased nutritional value, medicinal properties, enhanced taste and esthetic appeal. There remains concern that these benefits come with a cost to the environment or increased risk to the consumer. Most U.S. consumers are not aware of the extent that genetically modified foods have entered the marketplace. Consumer awareness of biotechnology seems to have increased over the last decade, yet most consumers remain confused over the science. Concern over the impact on the safety of the food supply remains low in the United States, but is substantially elevated in Europe. Before a genetically engineered crop is introduced into commerce it must pass regulatory scrutiny by as many as four different federal regulatory bodies to ensure a safe food supply and minimize the risk to the environment. Key areas for more research are evaluation of the nutritional benefits of new crops, further investigation of the environmental impact, and development of better techniques to identify and track genetically engineered products.

    2011-01-01

    Full Text Available Nanotechnology deals with the construction of new materials, devices, and different technological systems with a wide range of potential applications at the atomic and molecular level. Nanomaterials have attracted great attention for numerous applications in chemical, biological, and industrial world because of their fascinating physicochemical properties. Nanomaterials and nanodevices are being produced intentionally, unintentionally, and manufactured or engineered by different methods and released into the environment without any safety test. Nantoxicity has become the subject of concern in nanoscience and nanotechnology because of the increasing toxic effects of nanomaterials on the living organisms. Nanomaterials can move freely as compared to the large-sized particles; therefore, they can be more toxic than bulky materials. This review article delineates the toxic effects of different types of nanomaterials on the living organisms through different sources, like water, air, contact with skin, and the methods of determinations of these toxic effects.

    Parents influence their child's eating behavior and attitudes directly as food providers and indirectly through their parental feeding styles and feeding concerns and practices. Chinese American parents' practices are likely influenced by culture. The objective of this study was to explore the relationships between parental perceptions, feeding practices, feeding styles, level of parental acculturation (LPA), and child weight status via a self-administered questionnaire. This survey study involved a convenience sample of 712 individuals who were parents of 5- to 10-year old children attending Chinese language after-school programs. The prevalence of overweight was 11.5% and obesity was 11.1%. LPA was not directly predictive of child overweight in multiple regression but from categorical data, Chinese American parents tended to use indulgent (33.2%) and authoritarian (27.9%) feeding styles, with the former increasing with acculturation and the latter decreasing. Indulgent parents had more than expected overweight and obese children, and authoritarian and authoritative parents, fewer. LPA was negatively predictive of pressure to eat healthy foods (p Parental perceptions and concerns about child weight were predictors of child weight. Consequently, parental concerns and responsiveness to child needs without also encouragement (demandingness) to eat healthy foods (indulgent feeding style) may promote overweight. The authoritative parental feeding style may contribute to children having healthy weights and therefore healthy lives.

    2008-12-01

    GEO 311: Geoscience and Global Concerns is an undergraduate course taught at Stony Brook University during each fall semester. The class meets twice per week, with one session consisting of a lecture and the other, an interactive activity in a computer laboratory that engages the students in exploring real world problems. A specific concern or issue serves as a focus during each session. The students are asked to develop answers to a series of questions that engage them in identifying causes of the problem, connections with the Earth system, relationships to other problems, and possible solutions on both a global and local scale. The questions are designed to facilitate an integrated view of the Earth system. Examples of topics that the students explore during the laboratory sessions are: 1) fossil fuel reserves and consumption rates and the effect of their use on climate, 2) alternative sources of energy and associated technologies, such as solar photovoltaics, nuclear energy, tidal power, geothermal energy, and wind power, 3) effects of tsunamis and earthquakes on human populations and infrastructure, 4) climate change, and 5) hurricanes and storms. The selection and scheduling of topics often takes advantage of the occurrence of media attention or events that can serve as case studies. Tools used during the computer sessions include Google Earth, ArcGIS, spreadsheets, and web sites that offer data and maps. The students use Google Earth or ArcGIS to map events such as earthquakes, storms, tsunamis, and changes in the extent of polar ice. Spreadsheets are employed to discern trends in fossil fuel supply and consumption, and to experiment with models that make predictions for the future. We present examples of several of these activities and discuss how they facilitate an understanding of interrelationships within the Earth system.

  2. Aquaculture and feeding ecology: Feeding behaviour in turbot larvae

    DEFF Research Database (Denmark)

    Bruno, Eleonora

    challenging for larval rearing. After the start of exogenous feeding, another intense and likely critical period of change occurs in the early life stages of fish. This stage is the metamorphosis, during which the larvae transform organs and body morphology to become juveniles. Compared to other teleosts...... metamorphosis in flatfish species is often unsuccessful, resulting in different types of abnormal development. The objective of this thesis was to analyse the feeding behaviour of the flatfish species turbot (Psetta maxima L.) larvae during the two crucial life periods, 1) first feeding and 2) metamorphosis....... To analyse whether these two periods are critical for the correct development and survival of turbot, feeding behaviours of larvae during the period of first feeding and during the first stages of metamorphosis was studied using video recordings. This provided qualitative and quantitative descriptions...

    Child health is widely affected by nutritional status, and there is growing interest surrounding the possibility that child nutritional status and infant feeding practices may be linked to obesity in adulthood, increasing risks of metabolic complications. Prospective studies enable appropriate investigation and evaluation of the determinants of childhood development. The present paper therefore aimed to provide a review of the main evidence to date from longitudinal studies concerning the associations of infant feeding practices, patterns of childhood growth and nutritional status exhibited in adult life.

    2005-07-01

    A generic methodology for feeding strategy optimization is presented. This approach uses a genetic algorithm to search for optimal feeding profiles represented by means of artificial neural networks (ANN). Exemplified on a fed-batch hybridoma cell cultivation, the approach has proven to be able to cope with complex optimization tasks handling intricate constraints and objective functions. Furthermore, the performance of the method is compared with other previously reported standard techniques like: (1) optimal control theory, (2) first order conjugate gradient, (3) dynamical programming, (4) extended evolutionary strategies. The methodology presents no restrictions concerning the number or complexity of the state variables and therefore constitutes a remarkable alternative for process development and optimization.

    2006-01-01

    To measure and compare the activity of the masseter, temporalis and buccinator muscles in different infant feeding methods. Cross-sectional study of 60 full-term infants with no intercurrent diseases, aged between two and three months, classified into the following groups: 1) exclusive breastfeeding; 2) breastfeeding plus bottle-feeding; and 3) exclusive breastfeeding plus cup feeding. Surface electromyography was performed during infant feeding. The Krushal-Wallis test was used, complemented by multiple paired comparisons of the groups. A 5% significance level was chosen for the tests. Statistically higher results were verified in the breastfeeding group in relation to the bottle-feeding one, both in the range of movement and the mean contraction of the masseter. With regard to the temporalis muscle, statistically higher results were found in the breastfeeding group comparatively to the bottle-feeding one. As to the buccinator muscle, statistically higher results were observed in the breastfeeding group in relation to the bottle-feeding one, although in this case, the difference concerned only the range of contraction. The similarities between the muscle activity in the breastfeeding and in the cup-feeding groups suggests that cup-feeding can be used as an alternative infant feeding method, being better than bottle-feeding, due to the hyperactivity of the buccinator muscle, which could result in changes to the structural growth and development of the stomatognathic system functions.

  9. Feeding the feeble: steps towards nourishing preterm infants.

    Science.gov (United States)

    Obladen, Michael

    2015-09-01

    This paper describes historic steps in feeding techniques and knowledge on the nutritional needs of premature infants. Devices to overcome weak sucking and swallowing were developed from 1851 to 1920, including tube feeding by gavage, medicine droppers and pipettes, feeding bottles with an air inlet, and beaked spoons for nasal feeding. Indwelling nastrogastric tubes were in use from 1951. For alleged safety concerns in the 1950s, postnatal feeding was postponed until a week of starvation was reached, and studies showed an association with neurological handicaps. The premature infant's elevated need for energy, protein, and minerals has been established since 1919. However, these remained controversial, and nutritional practices continued to lag behind theoretical knowledge. Concentrated formula was developed in the 1940s, parenteral supplementation in the 1960s, and human milk fortifiers in the 1970s. In the 1990s, necrotizing enterocolitis was found to be more frequent in infants who were fed formula than in those who were fed human milk. Recently, probiotics were shown to reduce the risk of necrotizing enterocolitis. Nevertheless, compared with other aspects of neonatal medicine, there is still remarkably little evidence on how to feed preterm infants.

It will also look into the Revised Guidelines of the ICMJE vis-à-vis issues related to industry-sponsored research. Journals And Editors In the last chapter, we saw how conflict of interest related to individuals and institutions are discussed and resolved by AAMC. Conflict of interest because of industry's increasing clout has also engaged the attention of editors of important journals and some significant editorials in this connection are worth a close study by all concerned researchers and institutions, for they reflect reasoned responses to disturbing developments. The titles themselves reflect their concern:Is academic medicine for sale? (Angell, N Engl J Med , 2000Angell asks a piquant question of academic medical institutions:'Academic medical institutions are themselves growing increasingly beholden to industry. How can they justify rigorous conflict-of-interest policies for individual researchers when their own ties are so extensive?' Answering as to why Academia-industry connect flourishes, she says: 'Some academic institutions have entered into partnerships with drug companies to set up research centers and teaching programs in which students and faculty members essentially carry out industry research. Both sides see great benefit in this arrangement. For financially struggling medical centers, it means cash. For the companies that make the drugs and devices, it means access to research talent, as well as affiliation with a prestigious "brand." Asking herself the question: 'Why shouldn't clinical researchers have close ties to industry?' she answers it decisively tilts academia's inclinations to serve industry interests in various ways, rather than that of biomedical advance:'One obvious concern is that these ties will bias research, both the kind of work that is done and

  14. What Do We Feed to Food-Production Animals? A Review of Animal Feed Ingredients and Their Potential Impacts on Human Health

    Science.gov (United States)

    Sapkota, Amy R.; Lefferts, Lisa Y.; McKenzie, Shawn; Walker, Polly

    2007-01-01

    Objective Animal feeding practices in the United States have changed considerably over the past century. As large-scale, concentrated production methods have become the predominant model for animal husbandry, animal feeds have been modified to include ingredients ranging from rendered animals and animal waste to antibiotics and organoarsenicals. In this article we review current U.S. animal feeding practices and etiologic agents that have been detected in animal feed. Evidence that current feeding practices may lead to adverse human health impacts is also evaluated. Data sources We reviewed published veterinary and human-health literature regarding animal feeding practices, etiologic agents present in feed, and human health effects along with proceedings from animal feed workshops. Data extraction Data were extracted from peer-reviewed articles and books identified using PubMed, Agricola, U.S. Department of Agriculture, Food and Drug Administration, and Centers for Disease Control and Prevention databases. Data synthesis Findings emphasize that current animal feeding practices can result in the presence of bacteria, antibiotic-resistant bacteria, prions, arsenicals, and dioxins in feed and animal-based food products. Despite a range of potential human health impacts that could ensue, there are significant data gaps that prevent comprehensive assessments of human health risks associated with animal feed. Limited data are collected at the federal or state level concerning the amounts of specific ingredients used in animal feed, and there are insufficient surveillance systems to monitor etiologic agents “from farm to fork.” Conclusions Increased funding for integrated veterinary and human health surveillance systems and increased collaboration among feed professionals, animal producers, and veterinary and public health officials is necessary to effectively address these issues.

    The possible hazard of mycotoxin occurrence in foods and feeds and some food-borne mycotoxicoses is reviewed. Management of the risk of mycotoxin contamination using some useful preventive measures against mycotoxin contamination of foods/feeds during pre- and post-harvesting periods is considered. The physical and chemical methods of mycotoxin decontamination of foods/feeds are briefly described. The use of various feed additives as a method for prevention of the adverse effects of mycotoxins is reviewed. The processing of various foods and feeds is considered in a view to possible mycotoxin decontamination. The necessary hygiene control and risk assessment in regard to mycotoxin contamination of foods and feeds in addition to some useful prophylactic measures are briefly described. A short reference is made concerning the most successful methods of veterinary hygiene control in order to prevent a possible entering of some mycotoxins in commercial channels with a view to human health.

  17. Cholera: a great global concern.

    Science.gov (United States)

    2011-07-01

    Cholera, caused by the infection of toxigenic Vibrio cholerae (V. cholerae) to humans, is a life threatening diarrheal disease with epidemic and pandemic potential. The V. cholerae, both O1 and O139 serogroups, produce a potent enterotoxin (cholera toxin) responsible for the lethal symptoms of the disease. The O1 serogroup has two biotypes (phenotypes), classical and El Tor; each of which has two major serotypes (based on antigenic responses), Ogawa and Inaba and the extremely rare Hikojima. V. cholerae O1 strains interconvert and switch between the Ogawa and Inaba serotypes. Fluid and electrolyte replacement is the mainstay of treatment of cholera patients; the severe cases require antibiotic treatment to reduce the duration of illness and replacement of fluid intake. The antibiotic therapy currently has faced difficulties due to the rapid emergence and spread of multidrug resistant V. cholerae causing several outbreaks in the globe. Currently, cholera has been becoming endemic in an increasing number of geographical areas, reflecting a failure in implementation of control measures. However, the current safe oral vaccines lower the number of resistant infections and could thus represent an effective intervention measure to control antibiotic resistance in cholera. Overall, the priorities for cholera control remain public health interventions through improved drinking water, sanitation, surveillance and access to health care facilities, and further development of safe, effective and appropriate vaccines. Thus, this review describes the facts and phenomena related to the disease cholera, which is still a great threat mainly to the developing countries, and hence a grave global concern too.

  19. Schistosome feeding and regurgitation.

    Directory of Open Access Journals (Sweden)

    Patrick J Skelly

    2014-08-01

    Full Text Available Schistosomes are parasitic flatworms that infect >200 million people worldwide, causing the chronic, debilitating disease schistosomiasis. Unusual among parasitic helminths, the long-lived adult worms, continuously bathed in blood, take up nutrients directly across the body surface and also by ingestion of blood into the gut. Recent proteomic analyses of the body surface revealed the presence of hydrolytic enzymes, solute, and ion transporters, thus emphasising its metabolic credentials. Furthermore, definition of the molecular mechanisms for the uptake of selected metabolites (glucose, certain amino acids, and water establishes it as a vital site of nutrient acquisition. Nevertheless, the amount of blood ingested into the gut per day is considerable: for males ∼100 nl; for the more actively feeding females ∼900 nl, >4 times body volume. Ingested erythrocytes are lysed as they pass through the specialized esophagus, while leucocytes become tethered and disabled there. Proteomics and transcriptomics have revealed, in addition to gut proteases, an amino acid transporter in gut tissue and other hydrolases, ion, and lipid transporters in the lumen, implicating the gut as the site for acquisition of essential lipids and inorganic ions. The surface is the principal entry route for glucose, whereas the gut dominates amino acid acquisition, especially in females. Heme, a potentially toxic hemoglobin degradation product, accumulates in the gut and, since schistosomes lack an anus, must be expelled by the poorly understood process of regurgitation. Here we place the new observations on the proteome of body surface and gut, and the entry of different nutrient classes into schistosomes, into the context of older studies on worm composition and metabolism. We suggest that the balance between surface and gut in nutrition is determined by the constraints of solute diffusion imposed by differences in male and female worm morphology. Our conclusions have

    2011-01-01

    Organic waste from fish production is conventionally measured as BOD5 (biological oxygen demand measured during 5 days) and COD (chemical oxygen demand (includes BOD5)). Organic waste is of particular concern for several reasons. The easily degradable part (BOD5) may have an immediate, negative...... impact on the receiving water body by reducing dissolved oxygen concentrations and increasing sedimentation. Within aquaculture systems, a high organic load may affect fish health and performance directly (e.g., gill disease) as well as indirectly (proliferation of pathogenic bacteria and parasites......, reduction of dissolved oxygen concentrations, etc.). In recirculating aquaculture systems (RAS), a high organic load caused by limited water exchange may affect biofilter performance by favouring heterotrophic bacteria at the expense of autotrophic, nitrifying bacteria. Organic waste in RAS primarily...

    2016-12-01

    Background Feeding dysfunction occurs commonly in infants with single ventricle heart disease and impacts growth and long-term outcomes. Little evidence exists to guide safe feeding in this population. This study surveyed centers participating in the National Pediatric Cardiology Quality Improvement Collaborative to assess prevailing feeding practices amongthose caring for single ventricle neonates. Methods Web-based survey of 56 pediatric cardiac surgical centers was conducted. Questions addressed peri-operative feeding approaches and responses were presented and analyzed descriptively. Results Of 56 centers, 46 (82%) completed a survey. Preoperative feeding was common in single ventricle infants (30/46; 65%), routes varied. Centers who did not feed infants preoperatively cited the risk of necrotizing enterocolitis (16/16; 100%), presence of umbilical artery catheter (12/16; 75%), and prostaglandin infusion (9/16; 56%) as main concerns. 67% of centers reported no specific vital sign thresholds for withholding enteral feedings. In the postoperative period, most centers used an "internal guideline" (21/46; 46%) or an "informal practice" (15/46; 33%) to determine feeding readiness. Approaches to findings were significantly different among centers. About 40% of centers did not send patients home with feeding tubes, and there was no clear consensus between preferred feeding tube modality at discharge. Conclusion Considerable variation exists in feeding practices for infants with single ventricle congenital heart disease among 46 centers participating in a quality improvement collaborative. Although most centers generally feed infants preoperatively, feeding practices remain center-specific. Variability continues in the immediate post-operative and interstage periods. Further opportunities exist for investigation, standardization and development of best-practice feeding guidelines.

  2. Feed palatability and the alternative protein sources in shrimp feed

    Directory of Open Access Journals (Sweden)

    Chutima Tantikitti

    2014-02-01

    Full Text Available Feed palatability in carnivorous aquaculture species, shrimps in particular, has been crucially related to the presence of compounds acting as attractants that are commonly associated with the prey components under wild conditions. Thus a nutritionally adequate and organoleptically-pleasing diet is essential to achieve satisfactory intake and growth in shrimps. Historically, fishmeal has been an essential dietary component of intensive shrimp cultures because of its nutrient composition and compounds of high attractability. However, in recent years the fishmeal supplies have been dwindling due to over hunting, a diminishing natural fish-stock, elevating prices and market volatility. This has led to search for cheaper sources of suitable protein as fishmeal substitutes. To improve the palatability of diets, various substances have been investigated for their effectiveness in aqua-feed including natural feed ingredients and synthetic flavor substances. For crustacean, attractants characteristically are of low molecular weight, water and ethanol soluble, and amphoteric or basic compounds that are released from potential prey items. Compounds such as free amino acids, especially taurine, hydroxyproline, glycine, arginine, glutamic acid and alanine have been identified to stimulate feeding in shrimps. The same has been identified with organic acids, nucleotides and nucleosides, betaine, and some small peptides. Palatability also has been associated with animal’s past experience with the feed. Understanding the factors that regulate feed palatability is therefore primary for successful shrimp culture.

    To get insights into selection criteria for feed efficiency, 2 rabbit lines have been created: the ConsoResidual line was selected for residual feed intake (RFI) with ad libitum feeding and the ADGrestrict line was selected for ADG under restricted feeding. The aim of the present study was to evaluate the impact on carcass and meat quality of the genetic selections. This comparison was performed using 2 different feeding strategies corresponding to the selection design. Carcass and meat quality traits were recorded for the 3 lines (ConsoResidual, ADGrestrict, and an unselected control [generation 0 {G0}]) in the 2 feeding systems (ad libitum and restricted) for 163 animals. Concerning the line effect, the BW at 63 d old was higher for the ADGrestrict line compared with the G0 and ConsoResidual lines ( rabbits did not exhibit a different carcass yield but showed different carcass traits. Indeed, the ConsoResidual rabbits had a higher hind leg yield ( rabbits. The ADGrestrict line had an intermediate perirenal fat yield compared with the other 2 lines. The G0 line always exhibited higher fat yields. Concerning meat quality, the ConsoResidual rabbits showed a lower ultimate pH ( rabbits. The feeding level had a strong effect on the gastrointestinal tract ( = 0.0004) and the carcass yield ( = 0.001). The latter was decreased in restricted rabbits. The effects of feeding strategy on meat quality were detrimental in the case of restricted feeding. Even if the ultimate pH was slightly higher in restricted rabbits ( = 0.0002), the carcass chilling loss ( = 0.0005) and the drip loss during 6 d ( feed seems to be less adversely correlated with carcass traits and meat quality traits but it leads to an increase in the live weight of the rabbits. Adversely, the selection on RFI, without affecting growth rate, would not modify age at slaughter because growth rate is not affected, but it might induce detrimental effects on meat quality.

    1978-12-01

    Retrospective nutritional data on 100 children, aged 6 months to 2 1/2 years, who were admitted to the University Hospital in Kuala Lumpur, Malaysia, was obtained by interviewing the mothers of the children. Analysis of the data revealed that 1) only 49% of the children were breast-fed as infants; 2) 50% of the mothers who did breast-feed discontinued breast-feeding before the children were 3 months old; and 3) the weaning diet of at least 1/3 of the children was inadequate. 18% of the children were Malays, 49% were Chinese, and 33% were Indian. The proportion of breast-fed children was highest among the Malays and lowest among the Chinese. Mothers with higher incomes tended to stop breast-feeding earlier than mothers with lower incomes. 67% of the women said they stopped breast-feeding due to inadequate lactation. Most of the children received supplementary foods at relatively early ages. 50% of the infants received starchy foods by the time they were 3 1/2 months old, and 50% received fruit or fruit juice by the time they were 3 1/2 months old. Vegetable products, meat, fish, and eggs were not added to the diet until the children were considerably older. Recommendations, based on the study findings, were 1) hospitals should discontinue the practice of deferring breast-feeding initiation for 24 hours after delivery; 2) mothers should be encouraged to breast-feed fully; and 3) health personnel should discourage the widespread use of costly precooked cereals for supplementary feeding. Tables depicted 1) the frequency distribution of the 100 children by income and by milk feeding patterns according to ethnic affiliation and 2) the cost of serving precooked cereals as compared to the cost of serving home cooked meals.

The emphasis will be on feed whose incorporation into mixes could result in unfavorable effects on production, health and economic production of swine. Data will be presented on maize and its possible negative effects, having in mind toxins. Soybean meal, or genetically modified soybean meal, will also be observed. The next feed which will be discussed will be soybean whey obtained by different procedures and the potential dangers of its use in swine diet rations. Sunflower meal, feed of animal origin, with emphasis on fish flour and meat-bone flour will also be covered in the work. A feed which has been attracting particular attention lately is yeast imported from Italy. Its quality characteristics will be discussed, the so-called non-protein nitrogen. Analyses of mineral feed will include sources of phosphorus, phosphates (monocalciumphosphate, dicalcium phosphate phytases and resolving the problem of phosphorus in swine rations. Finally, an inevitable segment are synthetic amino acids, especially lysine and its role in swine diet.

    Children's eating behavior, food intake, and weight status are highly influenced by parents, who shape their food environment via parental feeding practices. The aim of this study was to investigate associations between sociodemographic, anthropometric, and behavioral/attitudinal characteristics of parents and their 5- to 9-year-old children and a range of positive ("healthy eating guidance," "monitoring") and potentially negative ("restriction for weight control," "restriction for health," "emotion regulation/food as reward," and "pressure") parental feeding practices. Parents completed a questionnaire assessing parental and child characteristics. Parental feeding practices were measured using a Brazilian adaptation of the Comprehensive Feeding Practices Questionnaire. To test associations between parent and child characteristics and parental feeding practices, we ran bivariate logistic regression models with parent and child characteristics as independent variables and high (above median) scores on individual parental feeding practices as outcome variables. We then conducted multivariate logistic regression models containing all parent and child characteristics, controlling for child age and maternal education. Lower parental perceived responsibility for child feeding, higher child use of screen devices, and higher child ultra-processed food intake were associated with lower scores on "healthy eating guidance" and "monitoring." Higher parental perceived responsibility for child feeding and concern about child overweight were associated with higher scores on "restriction for weight control" and "restriction for health." Parental perceptions of low weight and concern about child underweight, and higher perceived responsibility for child feeding, were associated with higher scores on "pressure." Greater intake of ultra-processed foods and lower maternal age were associated with higher scores on "emotion regulation/food as reward." Parental concerns and perceptions

    It has been easy to demonstrate, both in humans and animals, that the stresses which disturbed either the physiological homeostasis, the behavioural homeostasis or both simultaneously, induced the modifications of the food intake; these disorders often found expression in the inappropriate eating or, less frequently, in temporary anorectic phases. The most relevant hypotheses localized, in the anterior and median hypothalamus (paraventricular nuclei, ventral median nuclei, lateral hypothalamic area), the neurobiological mechanisms which were involved in this stress/eating behaviour relationship. In the brain, both aminergic and peptidergic systems were concerned; the stress-induced hyperphagia required the functionality of the dopamine, dorsal noradrenergic bundle and endogenous opioids of the central nervous system. The dramatic stress-induced anorexia was based upon the reciprocal actions of serotonin, norepinephrine and CRF systems. Other peptides, which some of them belonged to the brain-gut peptide group, could interfere with these mechanisms. The neuropeptides being common in the stress and eating physiological systems, the regulatory mechanisms were most coherent; nevertheless, the precise nervous structures and neurochemical circuits that produced the stress-induced hyperphagia or stress-induced anorexia, remain unknown.

    Feeding and eating difficulties are documented among the offspring of mothers with eating disorders. Understanding the perspective of mothers with eating disorders is likely essential to develop parent-based early prevention programs for children of these mothers. In the present study, twenty-nine mothers who were diagnosed with an eating disorder prior to becoming mothers and who currently had toddler age children participated in a semi-structured interview examining maternal functioning and child feeding. The maternal perceptions that emerged from the interviews were sorted into central themes and subcategories using interpretive phenomenological analysis. Data indicate that mothers with eating disorders express preoccupation with their child's eating, shape and weight, and many dilemmas about child feeding. They also reported rarity of family meals and their toddlers' preliminary awareness of maternal symptoms. Maternal concerns regarding child nutrition, feeding and weight were reported as more intense in regards to daughters. These maternal perceptions illuminate the maternal psychological processes that underlie the feeding and eating problems of the children of mothers with lifetime eating disorders. Findings should be addressed in the evaluation, treatment, and research of adult and childhood eating disorders.

    Full Text Available Utilization of yeast and or filamentous fungi as feed additive to ruminants has been of interest since the late 1980’s. Two fungi species have been commercially produced in the United States, (1 Yea-Sacc containing living cells of Saccharomyces cerevisiae and (2 Amaferm bearing Aspergillus oryzae fermentation extract. It has been demonstrated and proven that the cultures can enhance rumen development and function in young ruminants. This paper concerns the use of Aspergillus oryzae fermentation culture (AOFC as feed additive for young-growing male ‘Garut’ sheep. The A. oryzae was cultured in a media made of mineral-enriched ‘onggok’ flour, a material of tapioca processing waste. The AOFC was prepared gradually by incubating the fungus at room temperature (26 – 300C for 5 days, dried at 400C and ground. The AOFC was added to a commercial concentrate (GT-03 at 0, 5 and 10% (w/w levels, as treatment C0 (control, C1, and C2, respectively. Fifteen growing ‘Garut’ sheep were used and the concentrate feed treatments were randomly allotted based on a randomized block design. Drinking water was available at all time. The amount of feed offered (chopped King grass and concentrates and their refusals were weighed daily and live-weight of sheep was measured once a week in the morning. Daily feces was collected and weighed in the last 10 days of the 14-week experimental period. All feed and fecal samples were analyzed for dry matter, crude protein, total fiber (NDF, and ash. AOFC supplementation resulted in higher weight gains (P<0.05, which were 94.81; 122.08; and 140.52 g/d for C0, C1, and C2 treatments, respectively. Dry and organic matter, as well as protein intake was also significantly increased by inclusion of AOFC into concentrate diet (P<0.05. The increment in nutrient intake was from increased consumption of concentrates, and not from King grass, however, there was no effect of AOFC supplementation on feed efficiency.

    Full Text Available Background. Prelacteal feed (feeding any other substance before first breastfeeding appears to be common despite its harmful effects. By definition a child provided with prelacteal feed (PLF is not exclusively breastfed and PLF has many implications for the success and early initiation of breastfeeding. Objectives. To describe the prevalence of, nature of, and reasons for and factors associated with PLF. Methods. 647 mother-infant dyads were studied. Data was collected about the sociodemographic features of the family and baby, maternity care, the type of first feed before suckling, and causes of PLF. Maternal weight and height were measured and body mass index was calculated. Results. About 58% of newborns received prelacteal feeds. The commonest PLF was sugar/glucose water (39.6%. The most frequent reasons for giving PLF are tradition (61.0% and mother’s/mother in law’s advice (58.3%. The logistic regression revealed that the independent predictors of PLF are urban residence; maternal education; father’s education; low, middle, and high social class; maternal obesity; receiving antenatal care at private clinics and no antenatal care; Caesarean section; female babies; low birth weight; and admission to neonatal intensive care. Conclusion. Indiscriminate use of PLF should be discouraged in medical education and in antenatal maternal health education.

    With the outbreak of Bovine Spongiform Encephalopathy (BSE) (commonly known as mad cow disease) in 1987 in the United Kingdom and a recent case discovered in Alberta, more and more emphasis is placed on food and farm feed quality and safety issues internationally. The disease is believed to be spread through farm feed contamination by animal byproducts in the form of meat-and-bone-meal (MBM). The paper reviewed the available techniques necessary to the enforcement of legislation concerning the feed safety issues. The standard microscopy method, although highly sensitive, is laborious and costly. A method to routinely screen farm feed contamination certainly helps to reduce the complexity of safety inspection. A hyperspectral imaging system working in the near-infrared wavelength region of 1100-1600 nm was used to study the possibility of detection of ground broiler feed contamination by ground pork. Hyperspectral images of raw broiler feed, ground broiler feed, ground pork, and contaminated feed samples were acquired. Raw broiler feed samples were found to possess comparatively large spectral variations due to light scattering effect. Ground feed adulterated with 1%, 3%, 5%, and 10% of ground pork was tested to identify feed contamination. Discriminant analysis using Mahalanobis distance showed that the model trained using pure ground feed samples and pure ground pork samples resulted in 100% false negative errors for all test replicates of contaminated samples. A discriminant model trained with pure ground feed samples and 10% contamination level samples resulted in 12.5% false positive error and 0% false negative error.

    Full Text Available Modularization of concerns is important for software development. Object oriented programming paradigm provides an ease of modularization of basic concerns. There are some concerns whose implementation cannot be modularized using object oriented paradigm like profiling, logging etc. The implementation of such concernsremains scattered throughout the source code. Such concerns are called crosscutting concerns. Identification of crosscutting concerns plays an important role in aspect mining, defect detection and software maintenance. This paper gives a survey on the techniques used for identifying crosscutting concerns. We have compared eightdifferent techniques. The five of the eight techniques were applied on a tutorial application. The comparison has been done on five parameters like input required, output generated, availability of tools, stage of software development where the technique is applicable,the software on which the technique has already beenapplied.

    There are far too many children in the world who suffer from under-nutrition and growth faltering, with life time consequences such as reduced work capacity, increased infections, impaired intellectual performance and an increased risk of non communicable diseases later in life. These changes occur early in life, and consequently, complementary feeding has been receiving increased attention in the international nutrition community. In India, common problems relate not only to insufficient breastfeeding, but also to detrimental feeding practices. Only about 20% of children aged 6-23 months were fed according to the three recommended Infant and Child Feeding practices. The most common types of solid or semi-solid foods fed to both breastfeeding and non-breastfeeding children under 3 years of age were foods made from grains and roots. These complementary feeding practices were found to be significantly associated with poor socioeconomic status, undesirable socio-cultural beliefs, maternal illiteracy, and ignorance. Although many initiatives have been carried out in India to promote Infant and Young Child Feeding, the progress in reducing the number of undernourished children in India over the last decade has been slow and modest. Equally, with the growing evidence and interest in the role of infant nutrition in the development of over nutrition and non-communicable disease, it is important to plan appropriate complementary feeding interventions that result in optimal growth. Contact opportunities with parents, specifically mothers, must be used for counseling through multiple communication channels such as local media, in order to constantly educate the population with consistent and simple messages on child feeding.

  4. Scientific Opinion on the safety and efficacy of formaldehyde as a feed hygiene substance in feed for pigs and poultry

    Directory of Open Access Journals (Sweden)

    EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP

    2014-07-01

    Full Text Available The additive formaldehyde is an aqueous solution of formaldehyde (34–38 % w/w by specification and methanol (0.5–15.0 % v/v by specification, with a maximum concentration of formic acid of 0.05 %. It is applied for use as a feed hygiene substance in poultry and pigs. Concerning the safety assessment for target species, consumers, users and the environment, no new relevant data were provided which would lead the FEEDAP Panel to reconsider its two recent opinions on formaldehyde. Therefore, the FEEDAP Panel reiterates its former conclusions on the safety of formaldehyde when used as a feed additive. A safe level for poultry and pigs could not be determined. The proposed use of formaldehyde as a feed additive would not increase consumer exposure and consequently would not pose an additional risk to the consumer. No safe level of exposure of the skin, eyes or respiratory system to formaldehyde could be identified. Formaldehyde is not expected to accumulate in the environment and would therefore not pose a risk to the environment when used in animal nutrition. The additive has the potential to be effective in reducing bacterial growth in an already contaminated feed at a lowest concentration of about 200 mg/kg complete feed; the prevention of recontamination requires considerably higher concentrations. The efficacy data submitted for the additive formaldehyde fulfil the classical requirements for a preservative. The FEEDAP Panel notes that reducing the microbial load in contaminated feed does not reduce the hazards associated with bacterial toxins and endotoxins, which may already be present in feed.

    Full Text Available BACKGROUND Nutrients form the fuel for the body, which comes in the form of carbohydrates, proteins and lipids. The body is intended to burn fuels in order to perform work. Starvation with malnutrition affects the postoperative patients and patients with acute pancreatitis. There is an increased risk of nosocomial infections and a delay in the wound healing may be noted. They are more prone for respiratory tract infections. Enteral Nutrition (EN delivers nutrition to the body through gastrointestinal tract. This also includes the oral feeding. This study will review the administration, rationale and assess the pros and cons associated with the early initiation of enteral feeding. The aim of this study is to evaluate if early commencement of enteral nutrition compared to traditional management (delayed enteral feeding is associated with fewer complications and improved outcome-  In patients undergoing elective/emergency gastrointestinal surgery.  In patients with acute pancreatitis. It is also used to determine whether a period of starvation (nil by mouth after gastrointestinal surgery or in the early days of acute pancreatitis is beneficial in terms of specific outcomes. MATERIALS AND METHODS A prospective cohort interventional study was conducted using 100 patients from July 2012 to November 2012. Patients satisfying the inclusion and exclusion criteria were included in the study. Patients admitted in my unit for GIT surgeries or acute pancreatitis constituted the test group, while patients admitted in other units for similar disease processes constituted the control group. RESULTS Our study concluded that early enteral feeding resulted in reduced incidence of surgical site infections. When the decreased length of stay, shorter convalescent period and the lesser post-interventional fatigue were taken into account, early enteral feeding has a definite cost benefit.CONCLUSION Early enteral feeding was beneficial associated with fewer

    Pediatric obesity is multifactorial and difficult to treat. Parenting and feeding behaviors have been shown to influence a child's weight status. Most prior studies have focused on preschool-aged White children. Additional complicating factors include parents' inability to accurately identify their child's abnormal weight status. Parenting and feeding behaviors used by 176 African American and White parents of school-age children were examined. Assessment included (a) identifying what behaviors were reported when parent expressed concern with child's weight and (b) the relationship of these behaviors on child's body mass index percentile (BMI%), considering ethnicity, socioeconomic status (SES), and parent's body mass index (BMI). Findings included African American parents and parents concerned about their child's weight exhibited increased controlling/authoritarian parenting and feeding behaviors. Parents were able to accurately identify their child's weight status. Parenting and feeding behaviors played a significant role in the children's BMI% even when controlling for ethnicity, SES, and parent's BMI.

    Virginiamycin was extracted from the feed by ethanol-pH 2.5 phosphate buffer (1 + 1). The pH during extraction was adjusted (when necessary) to between 4 and 5. Sample dilutions and the standard dose response line were prepared to contain ethanol pH 6 phosphate buffer (2 + 8), and the test organism was Sarcina lutea. Three feeds (a poultry ration, a swine finishing ration, and a swine starter ration) showed virginiamycin recovery of 88.8--108.9% when standard solutions were added at concentrations of 4.54--90.8 g/ton. The coefficient of variation (4--20%) was larger for low potency feeds (10 g/ton) compared to the higher feeds (100 g/ton). Similarly, excellent recovery was obtained when the swine starter feed was fortified by a commercial premix. Amprolium, roxarsone, and monensin can be present at 20 times the concentration of virginiamycin with little or no interference in the antibiotic determination. Lasalocid at 10 times the concentration of virginiamycin caused a slightly positive bias (recovery, 107.4%).

    Near-infrared images of the active galaxy NGC 1097, obtained with the NACO adaptive optics instrument on ESO's Very Large Telescope, disclose with unprecedented detail a complex central network of filamentary structure spiralling down to the centre of the galaxy. These observations provide astronomers with new insights on how super-massive black holes lurking inside galaxies get fed. "This is possibly the first time that a detailed view of the channelling process of matter, from the main part of the galaxy down to the very end in the nucleus is released," says Almudena Prieto (Max-Planck Institute, Heidelberg, Germany), lead author of the paper describing these results. Located at a distance of about 45 million light-years in the southern constellation Fornax (the Furnace), NGC 1097 is a relatively bright, barred spiral galaxy seen face-on. At magnitude 9.5, and thus just 25 times fainter than the faintest object that can be seen with the unaided eye, it appears in small telescopes as a bright, circular disc. NGC 1097 is a very moderate example of an Active Galactic Nucleus (AGN), whose emission is thought to arise from matter (gas and stars) falling into oblivion in a central black hole. However, NGC 1097 possesses a comparatively faint nucleus only, and the black hole in its centre must be on a very strict "diet": only a small amount of gas and stars is apparently being swallowed by the black hole at any given moment. Astronomers have been trying to understand for a long time how the matter is "gulped" down towards the black hole. Watching directly the feeding process requires very high spatial resolution at the centre of galaxies. This can be achieved by means of interferometry as was done with the VLTI MIDI instrument on the central parts of another AGN, NGC 1068 (see ESO PR 17/03), or with adaptive optics [1]. Thus, astronomers [2] obtained images of NGC 1097 with the adaptive optics NACO instrument attached to Yepun, the fourth Unit Telescope of ESO's VLT

    1983-12-01

    This article summarizes the nutritional considerations, impact on infection and immunity, and psychosocial aspects of the breast versus bottle feeding debate and concludes with guidelines for reorganizing government health services to promote breastfeeding. Its aim is to encourage reappraisal on the part of physicians of the direct implications of infant feeding for the health and well-being of people in all societies, but especially in developing countries. As a result of widespread abandonment of breastfeeding in developing countries, marasmus and infant diarrhea have increased. Although the biologic advatages of breast over bottle feeding are indisputable, the social and economic advantages are more difficult to quantify. Many Third World women curtail breastfeeding to meet the conditions of employment; however, the economic advantages of artificial feeding diminish as one descends down the pay scale. The counterproductive trend toward bottle feeding has been compounded by adoption of this method on the part of the educated elite in Third World countries, including medical and nursing professionals, thus conferring on it as status associated with progress and affluence. The present trend can be reversed only if communities are convinced of the advantages of breastfeeding and make adjustments to facilitate this practice. Preparation for motherhood must be viewed as an integral function of the health care system, with emphasis placed on the nutrition of pregnant and lactating women, preparation for breastfeeding, and the initiation and continuation of breastfeeding. Obstetric units must actively discourage the removal of infants from their mothers or routine artificial feeding. In addition, facilities must be provided at workplaces for breastfeeding, the working day should be modified to allow brestfeeding, maternity leaves should be extended, and appropriate payments should be made to nursing mothers. The nutrition needs of infants must be viewed as a shared

    Enteral nutrition therapy is common practice in pediatric clinical settings. Often patients will receive a pump-assisted bolus feeding over 30 minutes several times per day using the same enteral feeding set (EFS). This study aims to determine the safest and most efficacious way to handle the EFS between feedings. Three EFS handling techniques were compared through simulation for bacterial growth, nursing time, and supply costs: (1) rinsing the EFS with sterile water after each feeding, (2) refrigerating the EFS between feedings, and (3) using a ready-to-hang (RTH) product maintained at room temperature. Cultures were obtained at baseline, hour 12, and hour 21 of the 24-hour cycle. A time-in-motion analysis was conducted and reported in average number of seconds to complete each procedure. Supply costs were inventoried for 1 month comparing the actual usage to our estimated usage. Of 1080 cultures obtained, the overall bacterial growth rate was 8.7%. The rinse and refrigeration techniques displayed similar bacterial growth (11.4% vs 10.3%, P = .63). The RTH technique displayed the least bacterial growth of any method (4.4%, P = .002). The time analysis in minutes showed the rinse method was the most time-consuming (44.8 ± 2.7) vs refrigeration (35.8 ± 2.6) and RTH (31.08 ± 0.6) ( P < .0001). All 3 EFS handling techniques displayed low bacterial growth. RTH was superior in bacterial growth, nursing time, and supply costs. Since not all pediatric formulas are available in RTH, we conclude that refrigerating the EFS between uses is the next most efficacious method for handling the EFS between bolus feeds.

    The influence of simulated inflorescence design on feeding behavior of 3 male Eugenes fulgens (Rivoli's hummingbird) and one female Lampornis clemenciae (Bluethroated hummingbird) was studied in the laboratory using artificial flowers. Five two-dimensional and three three-dimensional arrangements provided constant rewards per artificial flower. Visits to two-dimensional arrangements had more flower visits per feeding bout, proportionally more flower revisits, and shorter time between flowers than visits to three-dimensional arrangements. This suggests inflorescence design may influence pollen movement by hummingbirds.

    Childhood obesity is prevalent among ethnic minorities in the UK but little is known about parent feeding practices in these populations. We administered questionnaires assessing parental feeding behaviors and perceptions and concerns relating to child weight to White British (n = 271), South Asian (n = 59), and Black Afro-Caribbean (n = 42) parents of UK 3-5 year-olds. Child BMI z-scores were determined from measured heights and weights. South Asian and Black Afro-Caribbean parents exhibited greater pressure to eat than White British parents. Black Afro-Caribbean parents additionally scored higher on instrumental feeding and lower on monitoring, while South Asian parents scored higher on emotional feeding. Black Afro-Caribbean parents reported the greatest concern about both child overweight and underweight. Ethnic differences were unchanged by controlling for perceptions and concerns relating to child weight, or for actual BMI z, parent education, or household income. Exploratory analyses suggested some evidence for sex differences within ethnic groups. For example, South Asian parents of daughters scored higher than White British parents of daughters on emotional feeding, with no ethnic differences apparent for parents of sons. Our findings support considering variation in parent feeding behaviors and weight-related attitudes by parental ethnicity and child sex when developing obesity interventions.

    Understanding the contribution of caregiver feeding practices to adolescent diet and weight is important to refining caregiver roles within the context of adolescent obesity prevention and treatment. This secondary data analysis examined whether feeding practices of female caregivers differentiated persistently non-overweight (n = 29) from persistently obese (n = 47) adolescents. Families who previously participated in a cross-sectional study on correlates of obesity were recruited for this follow-up study. At the time of the follow-up study, anthropometric measures were taken for all female caregivers and adolescents, and caregivers completed the Child Feeding Questionnaire-Adolescent version. Socioeconomic, demographic, female caregiver anthropometric, and psychological (caregiver perceived self-weight and concern for adolescent overweight) variables were examined as predictors of feeding practices found to differentiate the two groups. Female caregivers of persistently obese adolescents reported significantly greater use of restriction and monitoring compared to female caregivers of persistently non-overweight adolescents. Restriction was predicted by female caregiver age and concern for adolescent overweight whereas monitoring was predicted by concern for adolescent overweight only. Caregiver feeding strategies may be an important target for adolescent obesity prevention and intervention efforts particularly among those with heightened concern about their teen’s weight status.

    The catalytic reforming of naphtha is one of the major refinery processes, designed to increase the octane number of naphtha or to produce aromatics. The naphtha used as catalytic reformer feedstock usually contains a mixture of paraffins, naphthenes, and aromatics in the carbon number range C{sub 6} to C{sub 10}. The detailed chemical composition of the feed is necessary to predict the aromatics and hydrogen production as well as the operation severity. The analysis of feed naphtha is usually reported in terms of its ASTM distillation curve and API or specific gravity. Since reforming reactions are described in terms of lumped chemical species (paraffins, naphthenes and aromatics), a feed characterisation technique should be useful in order to predict reforming operating conditions and detect feed quality changes. Unfortunately online analyzer applications as cromatography or recently introduced naphtha NMR [1] are scarce in most of refineries. This work proposes an algorithmic characterisation method focusing on its main steps description. The method could help on the subjects previously described, finally a calculation example is shown.

    Jones, C J; Bryant-Waugh, R

    2012-04-01

    Child feeding problems are often associated with parental factors which may influence and maintain difficulties. This paper reports the development, pilot and preliminary evaluation of a group intervention for mothers of children with feeding problems. Themes for the group were derived from a survey of parents and professionals. Three pilot interventions were conducted in order to make an assessment of the feasibility, acceptability and potential for achieving change in levels of maternal mood, parenting stress and concerns related to feeding. While single case analysis revealed little change in standardised measures of mood and parenting stress, participants valued the social and emotional support offered by the group and reported improvements in concerns and maladaptive behaviours related to feeding. An intervention which provides support and a sense of a shared experience appears to have beneficial effects for mothers of children with feeding problems and therefore, may offer a constructive means of supporting this population.

  12. Relation between humor and empathic concern.

    Hampes, W P

    2001-02-01

    A series of studies have shown that humor is associated with close interpersonal relationships and effective in reducing stress, which in turn enhances empathy. Therefore, it was hypothesized that humor and empathic concern would be positively correlated. The Empathic Concern subscale of the Empathy Questionnaire, the Coping Humor Scale, the Multidimensional Sense of Humor Scale, and the Situational Humor Response Questionnaire were given to 124 subjects. Scores on the Empathic Concern subscale were significantly correlated with those on each of the humor scales. Types of humor may be an important variable in the relationship between empathic concern and humor. Both humor and empathic concern are associated for people with emotional intelligence who use these to interact effectively with other individuals. As such, it was suggested that exploration would yield a relation between humor and emotional self-awareness, which is also associated with emotional intelligence.

    Full Text Available Ochratoxin A is cancerogenic, teratogenetic, immunotoxic and nephrotoxic The mentioned order stresses the importance of this toxin concerning its harm to human health. The harmful effects of ochratoxin A include the effects at molecular level, such as DNA fragmentation, protein synthesis inhibition gluconeogenesis, lipid peroxidation, disorder of oxydative phosphorization in mitochondria, inhibition of blood coagulation and apoptosis. The presence of ochratoxin A in a great number of food samples, both of plant and animal origin, is the obvious risk to human health, which is confirmed by the high incidence of this toxin in samples of human serum and milk. It could be stated, with certainty, that the above - mentioned facts are the reason for which the EU has paid great attention to this mycotoxin in recent years. This paper deals with the results of the analysis of the animal feed component samples for the period 2000-2003 concerning the ochratoxin A content. The analysed feed components were taken from the farms with significant health problems of animals (not monitoring. The samples were analysed by chromatography on a thin layer and with a limited detection method for ochratoxin A of 40 ppb. The analysis was carried out on 108 maize samples, 11 barley samples, 21 wheat samples, 42 sunflower pellets samples and 47 soybean pellets samples (Table 1. The samples of sunflower pellets were contaminated in the greatest percentage, which indicates the inadequate storage of this feed component.

  14. Child feeding and human rights

    Directory of Open Access Journals (Sweden)

    2006-12-01

    Full Text Available Abstract Background The human right to adequate food needs to be interpreted for the special case of young children because they are vulnerable, others make the choices for them, and their diets are not diverse. There are many public policy issues relating to child feeding. Discussion The core of the debate lies in differences in views on the merits of infant formula. In contexts in which there is strong evidence and a clear consensus that the use of formula would be seriously dangerous, it might be sensible to adopt rules limiting its use. However, until there is broad consensus on this point, the best universal rule would be to rely on informed choice by mothers, with their having a clearly recognized right to objective and consistent information on the risks of using different feeding methods in their particular local circumstances. Summary The obligation of the state to assure that mothers are well informed should be viewed as part of its broader obligation to establish social conditions that facilitate sound child feeding practices. This means that mothers should not be compelled to feed in particular ways by the state, but rather the state should assure that mothers are supported and enabled to make good feeding choices. Thus, children should be viewed as having the right to be breastfed, not in the sense that the mother is obligated to breastfeed the child, but in the sense that no one may interfere with the mother's right to breastfeed the child. Breastfeeding should be viewed as the right of the mother and child together.

  15. [Current views on breast feeding].

    Grüttner, R

    1983-07-01

    One of the greatest advantages of feeding exclusively breast-milk is the continuous provision of immunoglobulin A, especially during the first days of life, and of leucocytes with macrophage function as well as unspecific, antiinfectious agents like lactoferrin, lysozyme and neuraminic acid. It seems, that the organism is protected against allergic reactions at the mucosa level of the small intestine caused by the penetration of "foreign" protein by feeding exclusively breast-milk especially during the first weeks and months of life. During the first months of the infant's life an increased supply of iron results from the higher content of iron in breast-milk as compared to cow's milk, and the better absorption of the iron from breast-milk. Just because of this (the better provision with iron from natural food) solid foods should not be added to the infant's diet before 6 months of age. One of the disadvantages of breast-feeding is the passage of unwanted substances from breast-milk to the infant. First of all the chlorinated hydrocarbons have to be mentioned within this context. However, a decreasing tendency can be assumed according to recent investigations. An increasing tendency in breast-milk, though not confirmed, seems possible only for the polychlorinated biphenyls. Nevertheless, for the pediatrician no reason to advise against breast-feeding results from the unwanted admixtures of chlorinated hydrocarbons in breast-milk. One should rather vigorously propagate to feed as many children as possible exclusively with breast-milk over a period of 4 to 6 months.

    A feeding mechanism and method for feeding minute items, such as capacitors, resistors, or solder preforms. The mechanism is adapted to receive a plurality of the randomly-positioned and randomly-oriented extremely small or minute items, and to isolate, orient, and position the items in a specific repeatable pickup location wherefrom they may be removed for use by, for example, a computer-controlled automated assembly machine. The mechanism comprises a sliding shelf adapted to receive and support the items; a wiper arm adapted to achieve a single even layer of the items; and a pushing arm adapted to push the items into the pickup location. The mechanism can be adapted for providing the items with a more exact orientation, and can also be adapted for use in a liquid environment.

    The trial was conducted on 176 Hubbard male broilers, allotted into four groups of 44 animals each. The control group received a CBMS-free diet and the other groups were given feed containing 2.5, 5.0 and 7.5% CBMS, respectively. The trial started at 21 days of age and ended at 56 days of age. Growth rate was not affected by 2.5% CBMS. Feed efficiency was practically the same for the control group for the 2.5%-CBMS group but tended to worsen as the CBMS level increased. As far as dressing out percentages, health (checked by means of anatomo-phathological examination at slaughter), feather pattern and meat organoleptic characteristics were concerned, no differences could be detected. Water content and ash content of the carcasses tended to increase, whereas ether extract decreased as CBMS level increased. Fatty acid composition of abdominal fat pad was uniform for the four groups; in the case of myristic, oleic and linoleic acids significant differences were recorded, but these differences must be considered as biologically not relecent. Excreta water content increased as CBMS level increased.

    Full Text Available The opportunity of the presence of genetically modified organism (GMO forage crops in Indonesia is quite large. Although until now there is no single forage crop awarded safely crop in Indonesia, but several crop byproducts have been used as feed ingredient. The controversy over the presence of GMO plant cannot be avoided. There are a part of communities who could not accept the presence of GMO crops for some reasons. On the other hand, the producers claimed the advantages of the GMO crops such as reducing pesticide application, reducing cost of weeding, more tolerant to biotic and abiotic stresses, and increasing production, farmer’s income and welfare. For the opponent, the main concerns are environmental issues and the possibility of emerging diseases in animal as well as human being. The Biosafety Comission through Biosafety Technical Team has the authority to recommend whether GMO food or feed (and plants is safe or not safe to be consumed and grown in Indonesia after the assessment.

    Porcine Epidemic Diarrhea Virus (PEDV), Porcine Delta Corona Virus (PDCoV), and Transmissible Gastroenteritis Virus (TGEV) are major threats to swine health and contaminated feed plays a role in virus transmission. The objective of our study was to characterize inactivation of PEDV, PDCoV, and TGEV in various feed ingredient matrices. Samples of complete feed, spray dried porcine plasma, meat meal, meat and bone meal, blood meal, corn, soybean meal, and corn dried distillers grains with solubles were weighed (5 g/sample) into scintillation vials and inoculated with 1 mL of PEDV, PDCoV, or TGEV. Samples were incubated at room temperature for up to 56 days. Aliquots were removed at various time points followed by preparing serial 10-fold dilutions and inoculating in cell cultures to determine the amount of surviving virus. Inactivation kinetics were determined using the Weibull model, which estimates a delta value indicating the time necessary to reduce virus concentration by 1 log. Delta values of various ingredients were compared and analyzed as to their nutrient composition. Soybean meal had the greatest delta value (7.50 days) for PEDV (P < 0.06) as compared with all other ingredients. High delta values (P < 0.001) were observed in soybean meal for PDCoV (42.04 days) and TGEV (42.00 days). There was a moderate correlation between moisture content and the delta value for PDCoV (r = 0.49, P = 0.01) and TGEV (r = 0.41, P = 0.02). There was also a moderate negative correlation between TGEV survival and ether extract content (r = -0.51, P = 0.01). In conclusion, these results indicate that the first log reduction of PDCoV and TGEV takes the greatest amount of time in soybean meal. In addition to this, moisture and ether content appear to be an important determinant of virus survival in feed ingredients. PMID:28542235

  20. Are empathy and concern psychologically distinct?

    Researchers have long been interested in the relationship between feeling what you believe others feel-often described as empathy-and caring about the welfare of others-often described as compassion or concern. Many propose that empathy is a prerequisite for concern and is therefore the ultimate motivator of prosocial actions. To assess this hypothesis, the authors developed the Empathy Index, which consists of 2 novel scales, and explored their relationship to a measure of concern as well as to measures of cooperative and altruistic behavior. A series of factor analyses reveal that empathy and concern consistently load on different factors. Furthermore, they show that empathy and concern motivate different behaviors: concern for others is a uniquely positive predictor of prosocial action whereas empathy is either not predictive or negatively predictive of prosocial actions. Together these studies suggest that empathy and concern are psychologically distinct and empathy plays a more limited role in our moral lives than many believe.

    Research concerning child feeding practices has focused on children and adolescents, and little is known about how feeding practices used in childhood relate to eating behaviors and weight status in early adulthood. We assessed college students' and their parents' retrospective reports of child feeding practices used when the students were in middle childhood. We also assessed the college students' current reports of their eating behaviors using the Dutch Eating Behavior Questionnaire (DEBQ) and the Intuitive Eating Scale (IES), and measured their current BMI. Results showed that college students' and their parents' reports about previous parental use of child feeding practices were not correlated. Parent reports of their own use of child feeding practices were more related to students' eating behaviors and BMI than were students' recollections about feeding practices used by their parents. An analysis of gender effects showed that there were positive correlations between parental child feeding practices, BMI, and emotional eating for female students. These relationships did not exist for male students. The results suggest that child feeding practices recollected by parents are linked to the development of emotional eating and weight status of women in early adulthood.

    There is conflicting evidence concerning the relationship between breast feeding and wheezing illness. The objective of this study was to investigate whether there is any association between breast feeding and wheezing in children aged over 5 years and to discover possible sources of heterogeneity. An electronic search of MEDLINE and EMBASE databases was conducted from January 2000 to June 2010. In addition, reference lists from relevant publications were searched. Birth cohort, cross-sectional and case-control studies were included if they measured any breast feeding or exclusive breast feeding for 3 or 4 months. Wheezing illness, including asthma, was identified based on symptoms, reported diagnosis or objective criteria. Thirty-one publications were identified for meta-analysis. There was no association found between any or exclusive breast feeding and wheezing illness, although there was a high level of heterogeneity between the studies. Subgroup analysis revealed that any breast feeding slightly lowers the odds of wheeze (pooled odds ratio 0.92 [0.86, 0.98]) but slightly increases the odds of asthma defined by specific criteria (pooled odds ratio 1.10 [1.00, 1.22]). This meta-analysis does not provide evidence that breast feeding is protective against wheezing illness in children aged 5 years and over. The difference in the effects of breast feeding according to the nature of the wheezing illness highlights the importance of the heterogeneity of illness phenotypes.

    The risk of pregnancy in breastfeeding should be a concern of women. Family planning programs in the postnatal period contraceptive choices offer high efficiency. Breastfeeding is a natural contraception method (LAM) as a contraceptive shield has 98 % efficiency. Women should consider using an alternate contraceptive method when feeding requirements for this method to be effective are not met. Some of contraceptive alternatives in lactation include hormonal methods. According to the Medical Eligibility Criteria for Contraceptive Use WHO combined hormonal methods are contraindicated during breast feeding, hormonal progestogen only method are considered only in Group 3 and Group 1 immediate postpartum after 6 weeks postpartum. There are modifications to these criteria by the CDC and the UK for the use of these hormones in early in lactation.

    Not only is there a high prevalence of malnutrition among the elderly admitted to hospital and other institutions, but nutritional status seems to decline during admission, not only as a result of disease but also problems with catering and feeding policies, which are not well-geared to the needs of the sick. This results in high food wastage rates and inadequate macro- and micronutrient intakes to meet requirements. In the elderly, decreased portion size and increased energy, protein and micronutrient density have been shown to be effective in decreasing wastage and improving intake. Other strategies for improving intake are reviewed, including a better environment, a reduction in drugs causing anorexia, help with eating, and less interruption of meals by procedures and ward rounds. Targets for nutritional intake and aims of feeding are reviewed.

    Environment concern is one important aspect for supply chain sustainability (SCS). Nowadays, company's activities give a lot of impact on the environment. Through these activities, there are other SCS issue of environment were identified. In this paper, the proposed SCS issue of environmental concern will be determined from Corporate Sustainability Report (CSR). Using a total weightage of 0.333 (after dividing into three aspects of sustainability), each proposed issues will be classified according to the company activities in order to determined weightage for each issue. Those weightages then will be used in developing of score metric for SCS in design phase. Result shows that the carbon footprint is the major concern for SCS of environment while environmental management system is a lowest concern for SCS environment.

    2006-11-01

    The objective of this study was to determine the obstetric care providers' roles in breast-feeding promotion during prenatal care. A questionnaire addressing breast-feeding issues was sent to family practitioners (FP), obstetric-gynecologists (OB/GYN), and nurse midwives (NM) in Iowa, USA. All NM, 97% of FP, and 85% of OB/GYN reported asking infant feeding preference-usually only at the first prenatal visit. NM (73%) were most likely to provide extensive breast-feeding counseling. OB/GYN (68%) and FP physicians (90%) reported doing their own breast-feeding counseling. Breast examinations targeting future breast-feeding problems were done in 82% to 84% of patients. NM practices shared more information supportive of breast-feeding. Nearly all providers offered prenatal classes, but only 41% of FP offered breast-feeding classes. Free formula samples were available in 73% of FP, 54% of OB/GYN, and 36% NM offices. Pamphlets on formula feeding and also breast-feeding were readily available. Overall NM (64%) reported being strong breast-feeding advocates compared to only 13% of FP and 7% of OB/GYN. In conclusion, little promotion of breast-feeding occurs in most prenatal practice settings.

A nasogastric tube was blindly inserted and its placement was confirmed by the radiologist. Enteral nutrition was initiated but the patient began to vomit immediately. After reviewing the radiograph it was understood that a gastric loop in the tube and its tip pointing upwards did not allow a safe infusion of the feeding formula. It is not enough having the radiologist reporting that a nasogastric feeding tube is placed in the stomach; the inclusion in the report of specific warnings on any potential cause of malfunctioning of the device should be considered. The presence of a gastric loop should be taken into account as a cause of potential malfunctioning.

  20. Analysis of feeding preference experiments.

    Published studies of consumer feeding preferences using foods that experience autogenic change in mass, numbers, area, etc., on the time scale of a feeding trial fail to employ appropriate statistical analyses to incorporate controls for those food changes occurring in the absence of the consumer. The studies that run controls typically use them to calculate a constant "correction factor", which is subtracted prior to formal data analysis. This procedure constitutes a non-rigorous suppression of variance that overstates the statistical significance of observed differences. The appropriate statistical analysis for preference tests with two foods is usually a simple t-test performed on the between-food differences in loss of mass (or numbers, area, etc.) comparing the results of experimentals with consumers to controls without consumers. Application of this recommended test procedure to an actual data set illustrates how low replication in controls, which is typical of most studies of feeding preference, inhibits detection of an apparently large influence of previous mechanical damage (simulated grazing) in reducing the attractiveness of a brown alga to a sea urchin.

    Full Text Available The use of antibiotics as feed additive improves performance in livestock. However, scientific data related to the use of antibiotics in feed merge spreading of bacterial resistance in animal and human bodies, therefore the usage of antibiotics in animal production is restricted. This condition raise the utilization of natural antibiotic as functional feed such as phytogenics (essential oil, flavonoid, saponin, and tannin, enzyme, probiotic, and prebiotic to improve the livestock’s performance, quality, and health. Functional feeds increase profitability in animal husbandry production and its use is feeds are expected to be functional foods that may have positive effects in human nutrition.

    Feeding difficulties are common in children with cerebral palsy and have an effect on growth, nutritional state, general health, social interaction and behaviour and developmental outcomes. Many factors have an effect on feeding ability. Identification of these factors and amelioration of their impact on feeding difficulties is essential to promote adequate growth and nutrition. Appropriate assessment and management is best achieved by a multiprofessional team skilled in the care of children with cerebral palsy and feeding impairments. Feeding difficulties must be considered within the wider context of family and social circumstance.

    2012-01-01

    The current study surveyed mothers with daughters (N=386) to investigate how mothers’ concern about their daughters’ breast cancer risk influenced intentions to engage in preventive behaviors. Using Protection Motivation Theory as a framework, self-efficacy, response efficacy and level of concern were posited to influence protective behavioral intention in distinct ways. Results from regression analyses indicate that self-efficacy, response efficacy, and mothers’ concern are significant predictors of intentions to engage in preventive behaviors with daughters. Additionally, a content analysis of mothers’ open-ended reasons for their concern about their daughters’ breast cancer risk yield a list of specific concerns as well as trends that vary by concern level and individual comment valence. Implications for incorporating mothers’ concerns into breast cancer prevention messages are discussed as a novel strategy for campaign designers. PMID:22070448

    Feed-in tariffs (FITs) are the most prevalent policy used globally to reduce development risks, cut financing costs, and grow the renewable energy industry. However, concerns over escalating costs in jurisdictions with FIT policies have led to increased attention on cost control. Using case studies and market-focused analysis, this report from the National Renewable Energy Laboratory (NREL) examines strengths and weaknesses of three cost-containment tools: (1) caps, (2) payment level adjustment mechanisms, and (3) auction-based designs. The report provides useful insights on containing costs for policymakers and regulators in the United States and other areas where FIT policies are in development.

  6. Cue-Based Feeding in the NICU.

    Science.gov (United States)

    Whetten, Cynthia H

    In NICU settings, caring for neonates born as early as 23 weeks gestation presents unique challenges for caregivers. Traditionally, preterm infants who are learning to orally feed take a predetermined volume of breast milk or formula at scheduled intervals, regardless of their individual ability to coordinate each feeding. Evidence suggests that this volume-driven feeding model should be replaced with a more individualized, developmentally appropriate practice. Evidence from the literature suggests that preterm infants fed via cue-based feeding reach full oral feeding status faster than their volume-feeding counterparts and have shorter lengths of stay in the hospital. Changing practice to infant-driven or cue-based feedings in the hospital setting requires staff education, documentation, and team-based communication.

    Parental feeding practices and children's eating behaviours are inter-related and both have been implicated in the development of childhood obesity. However, research on the parent-child feeding relationship during the first few months of life is limited. The aim of this study was to examine the cross-sectional relationship between maternal feeding beliefs and practices and infant eating behaviours in a community sample. Mothers (N = 413) of 4 month old infants recruited during pregnancy for the New Beginnings: Healthy Mothers and Babies study self-reported feeding beliefs/practices and eating behaviours of their infants on established tools. Data on a comprehensive range of maternal and infant characteristics were also collected. Multivariable regression models were used to assess the associations between five feeding beliefs and practices and four eating behaviours, adjusting for key maternal and infant covariates. Mothers concerned about their infant becoming underweight rated the infant higher on satiety responsiveness and lower on enjoyment of food. Higher awareness of infant feeding cues was associated with higher infant enjoyment of food. Mothers concerned about their infant becoming overweight and those who used food to calm their baby rated the infant as higher on food responsiveness. Feeding to a schedule (vs on demand) was not associated with any of the infant eating behaviours. A relationship between maternal feeding beliefs and practices and infant eating behaviours is apparent early in life, therefore longitudinal investigation to establish the directions of this relationship is warranted.

    2010-01-01

    Context For many hospice caregivers, the constancy and difficulty of caregiving impact their physical quality of life and cause depression, psychological distress, guilt, loneliness, and restrictions on social activities. Objectives Deviating from traditional unidimensional research on hospice caregivers, this study explored the transactional nature of reciprocal suffering by examining caregiver concerns through four dimensions: physical, psychological, social, and spiritual. Methods Researchers analyzed audiotapes of intervention discussions between hospice caregivers and research social workers. Results Results indicated that of the 125 pain talk utterances, the majority referenced psychological concern (49%), followed by physical (28%), social (22%), and spiritual (2%). Reflections on concerns revealed a global perspective of caregiving, which highlighted the patient’s needs juxtaposed to the caregiver’s recognized limitations. Conclusion By examining the reciprocal nature of suffering for caregivers, this study reinforced the need for assessing caregivers in hospice care, with specific emphasis on the importance of providing caregiver education on pain management.

    Breast feeding is a management problem requiring knowledge of the physiology of lactation, maternal and infant nutritional requirements, and specifics such as drugs which enter the milk. The job of the physician is to allay anxiety; this helps establish the let-down reflex and increases milk production. "Caking," mastitis and even abscesses are not indications for weaning. Rest, warm compresses and frequent nursing are indicated. Breast-fed infants have less tendency to obesity than those who are bottle-fed. Early solid foods in the diet are not needed.

    Exclusive breastfeeding is the best start an infant can receive. However, in many high-income countries breastfeeding rates are low and this may be a reflection of social norms which in turn may be influenced by the media. This study therefore explored the portrayal of infant feeding in women's general interest magazines. The five top selling women's weekly magazines in Britain and Ireland for 2013 over a 4-month period were included. A quantitative and qualitative content analysis was conducted for both written and visual content. In 58 magazines, there were 90 references to infant feeding with an average of 1.5 (range: 0-5) per magazine. Breastfeeding and formula feeding references were present in equal number and both were predominantly portrayed positively. There was only 1 visual representation of breast feeding compared with 11 of bottle feeding. Potential drivers for breastfeeding included its role in post-pregnancy weight loss and celebrity endorsement while family routine, the role of males in the house and concerns about adverse health effects were identified as barriers to breastfeeding. An improvement in visual representations of breast feeding and factual information in women's weekly magazines may be helpful in re-defining social norms regarding infant feeding. Keywords: food and nutrition, health promotion, public health.

    This paper describes the development and validation of a 27-item caregiver-reported questionnaire on toddler feeding. The development of the Toddler Feeding Behavior Questionnaire was based on a theory of interactive feeding that incorporates caregivers' responses to concerns about their children's dietary intake, appetite, size, and behaviors rather than relying exclusively on caregiver actions. Content validity included review by an expert panel (n = 7) and testing in a pilot sample (n = 105) of low-income mothers of toddlers. Construct validity and reliability were assessed among a second sample of low-income mothers of predominately African-American (70%) toddlers aged 12-32 mo (n = 297) participating in the baseline evaluation of a toddler overweight prevention study. Internal consistency (Cronbach's α: 0.64-0.87) and test-retest (0.57-0.88) reliability were acceptable for most constructs. Exploratory and confirmatory factor analyses revealed 5 theoretically derived constructs of feeding: responsive, forceful/pressuring, restrictive, indulgent, and uninvolved (root mean square error of approximation = 0.047, comparative fit index = 0.90, standardized root mean square residual = 0.06). Statistically significant (P relations between feeding behaviors, toddler overweight status, perceived toddler fussiness, and maternal mental health. The Toddler Feeding Behavior Questionnaire adds to the field by providing a brief instrument that can be administered in 5 min to examine how caregiver-reported feeding behaviors relate to toddler health and behavior.

    A key concern in animal feed factories is guaranteeing the correct labeling of compound feeds. Therefore, due to incorrect labeling, there is an urgent need for new control methods on the claims that can be made. In this study, this question has been tackled with different multivariate classification algorithms based on the near-infrared spectral fingerprint obtained from a given compound feed analyzed in its original physical market presentation form (i.e., cubes, coarse meals, pellets). The objective of this paper is the evaluation of different methods for establishing a separation among 24 feed types. Two linear methods, soft independent modeling of class analogy (SIMCA) and partial least squares (PLS) with two approaches to classification (PLSD and PLS-LDA); and one nonlinear method, support vector machines (SVM), were studied. The database used had the following structure: a first division was made between granules and meals; within these two groups, there was a second division according to three animal species to which the feed was marketed (bovine, ovine, and porcine); within each species there was a third division according to the age or physiological status of the animal (i.e., lactating dairy cattle, starters, etc.). Given the database structure, all the methods were evaluated following two strategies: (1) development of a model composed of the nine classification models corresponding to the structure of the data; and (2) development of a unique model that discriminates among the 24 classes of different feeds. With both strategies the lowest percentage of misclassified samples was achieved with the SVM method (3.96% with strategy 1 and 2.31% with strategy 2). Among the linear methods evaluated, SIMCA yielded the best results, with a percentage of 8.47% misclassified samples with strategy 1 and 4.05% misclassified samples with strategy 2. The results in this study show the ability of near-infrared spectroscopy to make acceptable classifications of feed

    Two experiments were conducted to evaluate the effect of moderate feed restriction on productivity of lambs classified on the basis of phenotypic expression of residual feed intake (RFI). In Exp. 1, 58 fat-tailed Kurdi ram lambs (32.1 ± 4.2 kg BW) were individually fed, ad libitum, a pelleted diet (35% alfalfa hay and 65% concentrate). Feed intake and ADG were determined for a 6-wk period and 3 feed efficiency measures including RFI, G:F, and partial efficiency of maintenance (PEM) were calculated. The lambs were sorted based on RFI and the 16 highest RFI (RFI ≥ mean + 0.5 SD) and 16 lowest RFI (RFI ≤ mean - 0.5 SD) lambs were subjected to body composition (BC) and DM digestibility (DMD) analysis. Feeding behavior traits (FB) were also evaluated for 24 h using a regular 5-min interval observation method. The high- and low-RFI lambs (14 lambs/RFI group) so classified in Exp. 1 were used in Exp. 2. Half of the lambs in each RFI group were randomly selected to be fed ad libitum or 85% of ad libitum (restricted feeding), which resulted in 4 experimental groups: 1) ad libitum high-RFI, 2) feed restricted high-RFI, 3) ad libitum low-RFI, and 4) feed restricted low-RFI. The lambs were fed the same diet as Exp. 1, and growth efficiency during a 6-wk test period as well as BC, DMD, and FB were also determined in Exp. 2. In Exp. 1, the low-RFI lambs consumed 14% ( feed than high-RFI lambs. Differences were also observed between high- and low-RFI groups for G:F ( = 0.01), RFI ( 0.72), and FB ( > 0.24). In Exp.2, the restriction feeding regime negatively affected ADG ( feed restriction condition. No effects of feed restriction on DMD ( = 0.87) and BC ( > 0.05) were observed. The lambs fed at the restricted level of intake presented a greater time ( feeding events were decreased ( feed restriction, no interaction ( > 0.05) was detected between RFI phenotype and feeding regime for FB. In summary, feeding high-RFI lambs at 85% of ad libitum level improved G:F with no effect

    Full Text Available ABSTRACT Objective: To draw attention to the importance of interaction between caregiver and child during feeding and the influence of parenting style on dietary habit formation. Source of data: A search was performed in the PubMed and Scopus databases for articles addressing responsive feeding; the articles considered most relevant by the authors were selected. Synthesis of data: The way children are fed is decisive for the formation of their eating habits, especially the strategies that parents/caregivers use to stimulate feeding. In this context, responsive feeding has been emphasized, with the key principles: feed the infant directly and assist older children when they already eat on their own; feed them slowly and patiently, and encourage children to eat but do not force them; if the child refuses many types of foods, experiment with different food combinations, tastes, textures, and methods of encouragement; minimize distractions during meals; and make the meals an opportunity for learning and love, talking to the child during feeding and maintaining eye contact. It is the caregiver's responsibility to be sensitive to the child's signs and alleviate tensions during feeding, and make feeding time pleasurable; whereas it is the child's role to clearly express signs of hunger and satiety and be receptive to the caregiver. Conclusion: Responsive feeding is very important in dietary habit formation and should be encouraged by health professionals in their advice to families.

  8. Residual feed intake in beef cattle

    J P.F. Arthur

    2008-07-01

    Full Text Available Providing feed is a major input cost in beef production, hence improvements in the efficiency of feed utilisation will reduce the cost of production. Residual feed intake (RFI is a measure of feed efficiency, and is defined as the difference between an animal's actual feed intake and its expected feed intake based on its size and growth. It is independent of the level of production, and the lower the value the more efficient the animal is. This paper examines the current state of knowledge on RFI. Available information indicates that postweaning RFI is moderately heritable, and that selection for low RFI will result in progeny that consume less feed for the same level of production as progeny of high RFI cattle. Under ad libitum feeding, RFI is phenotypically independent of growth traits. There is a weak genetic relationship between RFI and fatness but additional studies are needed to assess the magnitude of this relationship in different breeds, sexes, ages and feeding regimes. Residual feed intake is believed to represent inherent variation in basic metabolic processes which determine efficiency. Economic analyses of genetic improvement schemes that incorporate testing of individuals for RFI have yielded substantial economic benefits over and above existing schemes that do not include RFI testing. Selection for low RFI has an additional benefit of reducing greenhouse gas emissions by cattle.

    2017-03-02

    This study aimed to obtain insights into the presence of cadmium, lead, mercury and arsenic in feed materials and feed over time, for the purpose of guiding national monitoring. Data from the Dutch feed monitoring program and from representatives of the feed industry in the period 2007-2013 were used. Data covered the concentrations of cadmium, lead, mercury and arsenic in a variety of feed materials and compound feeds in The Netherlands. Trends in the percentage of samples that exceeded the maximum limit (ML), set by the European Commission, and trends in average, median and 90(th) percentile concentrations of each of these elements per feed material or compound feed were investigated. Based on the results, monitoring for cadmium, lead, mercury and arsenic should focus on feed material of mineral origin, feed material of marine origin, especially fish meal, seaweed and algae as well as feed additives belonging to the functional groups of (i) trace elements (notably cupric sulphate, zinc oxide and manganese oxide for arsenic) and (ii) binders and anti-caking agents. Mycotoxin binders are a new group of feed additives that also need attention. For complementary feed it is important to make a proper distinction between mineral and non-mineral feed because the ML in the latter group is usually lower. In seaweed/algae products a relatively large number of samples contained arsenic concentrations that exceeded the ML. Forage crops in general do not need high priority in monitoring programs, although for arsenic grass meal still needs attention.

    Full Text Available The current paper reviews on genetically modified crops and its impact on environment. The need forscreening and testing increases as more changes are made, and "second-generation" GMs will require more testing. Todate no adverse health effects caused by products approved for sale have been documented, although two productsfailed initial safety testing and were discontinued, due to allergic reactions. Most feeding trials have observed no toxiceffects and saw that GM foods were equivalent in nutrition to unmodified foods, although a few reports attributephysiological changes to GM food. However, some scientists and advocacy groups such as Greenpeace and WorldWildlife Fund consider that the available data do not prove that GM food does not pose risks to health, and call foradditional and more rigorous testing before marketing genetically engineered food [3]. Therefore, before a crop isdeclared environment friendly safety assessment is recommended. If any safety concern is identified, the risk associatedwith it should be characterized to determine effect on human health. Subsequent assessments should consider factorssuch as toxicity, allergenicitY, antinutrients and metabolites, the stability of the inserted gene and nutritionalmodification associated with genetic modification. If the entire assessment of these factors concludes that the GM foodin question is as safe as its conventional counterpart, the food is then considered safe to eat.

    With the emergence of transgenic technologies, new ways to improve the agronomic performance of crops for food, feed, and processing applications have been devised. In addition, ability to express foreign genes using transgenic technologies has opened up options for producing large quantities of commercially important industrial or pharmaceutical products in plants. Despite this high adoption rate and future promises, there is a multitude of concerns about the impact of genetically modified (GM) crops on the environment. Potential contamination of the environment and food chains has prompted detailed consideration of how such crops and the molecules that they produce can be effectively isolated and contained. One of the reasonable steps after creating a transgenic plant is to evaluate its potential benefits and risks to the environment and these should be compared to those generated by traditional agricultural practices. The precautionary approach in risk management of GM plants may make it necessary to monitor significant wild and weed populations that might be affected by transgene escape. Effective risk assessment and monitoring mechanisms are the basic prerequisites of any legal framework to adequately address the risks and watch out for new risks. Several agencies in different countries monitor the release of GM organisms or frame guidelines for the appropriate application of recombinant organisms in agro-industries so as to assure the safe use of recombinant organisms and to achieve sound overall development. We feel that it is important to establish an internationally harmonized framework for the safe handling of recombinant DNA organisms within a few years.

    Recent outbreaks of food-borne diseases highlight the need for reducing bacterial pathogens in foods of animal origin. Animal enteric pathogens are a direct source for food contamination. The ban of antibiotics as growth promoters (AGPs) has been a challenge for animal nutrition increasing the need to find alternative methods to control and prevent pathogenic bacterial colonization. The modulation of the gut microbiota with new feed additives, such as probiotics and prebiotics, towards host-protecting functions to support animal health, is a topical issue in animal breeding and creates fascinating possibilities. Although the knowledge on the effects of such feed additives has increased, essential information concerning their impact on the host are, to date, incomplete. For the future, the most important target, within probiotic and prebiotic research, is a demonstrated health-promoting benefit supported by knowledge on the mechanistic actions. Genomic-based knowledge on the composition and functions of the gut microbiota, as well as its deviations, will advance the selection of new and specific probiotics. Potential combinations of suitable probiotics and prebiotics may prove to be the next step to reduce the risk of intestinal diseases and remove specific microbial disorders. In this review we discuss the current knowledge on the contribution of the gut microbiota to host well-being. Moreover, we review available information on probiotics and prebiotics and their application in animal feeding.

    Germany and several other countries are areas of severe iodine deficiency. In addition to iodized salt additional strategies to fight iodine deficiency exist. A promising possibility is the supplementation of feed with iodine, in order to increase its content in food of animal origin. In a feeding experiment 24 male castrated and female piglets of the cross breed Deutsche Landrasse x Pietrain were fed a high iodine supplemented diet. At a body weight of 100 kg the animals were slaughtered and the effect of the iodine supplementation on iodine content in the organs was studied. Animals receiving 30 mg iodine/kg feed showed significantly higher iodine contents in muscle, heart, kidney, liver, serum, fat and in the thyroidea than animals receiving no iodine supplementation. The iodine content in muscle and organs increased by a factor three to seven. Concerning meat quality and other slaughter parameters there was no difference between the two groups. This demonstrates that this strategy is in addition to iodized salt a possibility to reduce iodine deficiency.

    To determine the effect of rice porridge feeding before elective surgery on preoperative gastric fluid pH, volume and starvation, a prospective study was undertaken in pediatric patients. Twenty healthy children ranged in age from 5 to 12 years were allocated randomly to either a fasted or rice porridge group. The children of fasted group (control group) were allowed to take solid food until midnight before the operation. The rice porridge group (study group) patients received a small amount of rice porridge 5 hours 30 minutes before the induction of anesthesia. The patients of both groups were permitted to take clear fluid until 5 hours before the induction of anesthesia. After the induction of anesthesia, gastric fluid was aspirated through an orogastric tube. The mean gastric fluid volume was 0.43 +/- 0.32 ml.kg-1 in the control group and 0.5 +/- 0.6 ml.kg-1 in the study group. The mean gastric fluid pH was 1.43 +/- 0.27 ml.kg-1 in the control group and 1.89 +/- 0.75 ml.kg-1 in the study group. There were no significant differences between the two groups concerning the gastric fluid volume and pH. The patient of the study group complained of less hunger. Preoperative rice porridge feeding is a possible preoperative feeding for pediatric patients.

    Efficiency of production is increasingly important with the current escalation of feed costs and demands to minimize the environmental footprint. The objectives of this study were 1) to estimate heritabilities for daily feed consumption and residual feed intake and their genetic correlations with production and egg-quality traits; 2) to evaluate accuracies of estimated breeding values from pedigree- and marker-based prediction models; and 3) to localize genomic regions associated with feed efficiency in a brown egg layer line. Individual feed intake data collected over 2-wk trial periods were available for approximately 6,000 birds from 8 generations. Genetic parameters were estimated with a multitrait animal model; methods BayesB and BayesCπ were used to estimate marker effects and find genomic regions associated with feed efficiency. Using pedigree information, feed efficiency was found to be moderately heritable (h(2) = 0.46 for daily feed consumption and 0.47 for residual feed intake). Hens that consumed more feed and had greater residual feed intake (lower efficiency) had a genetic tendency to lay slightly more eggs with greater yolk weights and albumen heights. Regions on chromosomes 1, 2, 4, 7, 13, and Z were found to be associated with feed intake and efficiency. The accuracy from genomic prediction was higher and more persistent (better maintained across generations) than that from pedigree-based prediction. These results indicate that genomic selection can be used to improve feed efficiency in layers.

    2012-02-01

    Researchers use the Caregiver's Feeding Styles Questionnaire (CFSQ) to categorize parent feeding into authoritative, authoritarian, indulgent, and uninvolved styles. The CFSQ assesses self-reported feeding and classifies parents using median splits which are used in a substantial body of parenting literature and allow for direct comparison across studies on dimensions of demandingness and responsiveness. No national norms currently exist for the CFSQ. This paper establishes and recommends cutoff points most relevant for low-income, minority US samples that researchers and clinicians can use to assign parents to feeding styles. Median scores for five studies are examined and the average across these studies reported.

    To assess the botulism hazard in fur animal feed production, 236 fur animal feed components and feed samples were analysed for Clostridium botulinum by detecting BoNT-encoding genes (botA, botB, botC, botE or botF) by PCR and for sulphite-reducing clostridia (SRC) by iron sulphite agar. The quality of the hazard analysis of critical control points (HACCP) -based in-house control system (IHCS) was evaluated with respect to botulism risk in feed plants (n=32). The overall prevalence of C. botulinum was 13% in different feed components and 5% in feed. The estimated MPN count of C. botulinum in feed components was 6.4 × 10(3)/kg at the highest and was shown to poorly correlate with SRC count. The critical control points in IHCSs were variable, and control limits were improperly set in most feed-producing plants. C. botulinum possesses a persistent safety hazard for fur animals by feed production, and control practices should be reassessed.

    A content analysis of 141 articles on breast feeding by discipline revealed differences in the factors considered necessary for breast feeding success and in the criteria used to determine success. Whereas medical articles focused on maternal factors prenatally and infant health post-natally, or the length of time breast feeding was maintained, lay articles focused on the relationship of the mother with her infant (the nursing couple) and the mother's ability to manage breast feeding within the family context. The implications of this discrepancy for nursing practice and research are discussed.

    2005-01-01

    Scrapie is a small ruminant, transmissible spongiform encephalopathy (TSE). Although in the past scrapie has not been considered a zoonosis, the emergence of bovine spongiform encephalopathy, transmissible to humans and experimentally to sheep, indicates that risk exists for small ruminant TSEs in humans. To identify the risk factors for introducing scrapie into sheep flocks, a case-control study was conducted in France from 1999 to 2000. Ninety-four case and 350 control flocks were matched by location and main breed. Three main hypotheses were tested: direct contact between flocks, indirect environmental contact, and foodborne risk. Statistical analysis was performed by using adjusted generalized linear models with the complementary log-log link function, considering flock size as an offset. A notable effect of using proprietary concentrates and milk replacers was observed. The risk was heterogeneous among feed factories. Contacts between flocks were not shown to be a risk factor.

    2015-01-01

    Tidal disruption events (TDEs) occur when a star, passing too close to a massive black hole, is ripped apart by tidal forces. A less dramatic event occurs if the star orbits just outside the tidal radius, resulting in a mild stripping of mass. Thus, if a star orbits a central black hole on one of these bound eccentric orbits, weaker outbursts will occur recurring every orbital period. Thanks to five Swift observations, we observed a recent flare from the close by (92 Mpc) galaxy IC 3599, where a possible TDE was already observed in December 1990 during the Rosat All-Sky Survey. By light curve modeling and spectral fitting, we account for all these events as the non-disruptive tidal stripping of a single star into a 9.5 yr highly eccentric bound orbit. This is the first example of periodic partial tidal disruptions, possibly spoon-feeding the central black hole.

The resolution of these uncertainties may require adjustments in the technology program before it can be commercialized. The impacts and concerns presented in the document are treated generically without reference to specific predetermined sites unless these are known. Hence, site-specific implications are not generally included in the assessment. The report consists of two main sections which describe the energy resource base involved, characteristics of the technology, and introduce the environmental concerns of implementing the technology; and which review the concerns related to wood combustion systems which are of significance for the environment. It also examines the likelihood and consequence of findings which might impede wood commercialization such as problems and uncertainties stemming from current or anticipated environmental regulation, or costs of potential environmental controls. This document is not a formal NEPA document. Appropriate NEPA documentation will be prepared after a formal wood combustion commercialization program is approved by DOE.

    Recent research suggests that the resurgence of bed bugs in the U.S. has occurred at an alarming rate. Assumptions have been made that socioeconomic status is not associated with the prevalence of bed bug infestations. Little information is available at the local level, however, about the prevalence of bed bugs in private homes. The authors' pilot study aimed to identify prevalence, knowledge, and concern about bed bugs in one higher income village in Ohio utilizing survey methodology. Responses from 96 individuals who completed the Prevalence, Knowledge, and Concern About Bed Bugs survey were utilized for analysis. The majority of the sample respondents were white and 95% reported that they owned their residence. Only 6% knew someone with bed bugs. Additionally, 52% reported they were somewhat concerned about bed bugs. About 46% reported that they had changed their behavior. For a higher income area, the prevalence was dissimilar to the rate reported in the general public (about 20%). This suggests that bed bugs may be an environmental issue effecting low-income populations disproportionately. Further research is needed in areas of differing socioeconomic levels.

    Although the pathogenesis of childhood obesity is multi factorial, maternal obesity and parenting have major roles. The aim of this study was to evaluate the influence of maternal obesity on feeding practices toward their obese school children. Obese children and adolescents referred to the pediatric endocrinology department were enrolled consecutively. Height and weight of all children and their mothers were measured. Maternal feeding practices were measured using an adapted version of the Child Feeding Questionnaire (CFQ). Answers were compared between obese (Body Mass Index [BMI] ≥ 30 kg/m2) and non-obese mothers. A total of 491 obese subjects (292 girls, mean age 12.0 ± 2.8 years) and their mothers participated in this study. A direct correlation between children's BMI and their mothers' BMI was found (Pobese in the study, only half of them consider themselves as obese. No difference were found in the scores of the subscales "perceived responsibility", "restriction", "concern for child's weight" and "monitoring" between obese and non-obese mothers. Child's BMI-SDS positively correlated with mothers' personal weight perception, concern for child's weight and restriction after adjustment for child's age (P children's BMI-z-scores. The degree of child's obesity increases mothers' concern and food restriction behavior. While mothers of obese children have a high prevalence of obesity, maternal obesity was found to have no significant influence on feeding behavior of obese school children.

    Liquid feeding system has been introduced to domestic swine farms, but negative cognition about liquid feeding system has been remained for feed waste decay related with poor management and microbial contamination. For these reasons, this study was conducted to evaluate the effects of feeding method in lactating sows. A total of 30 mixed-parity (average 4.13) lactating sows (Yorkshire × Landrace) with an initial BW of 218.8 ± 19.5kg was used in a 3 week trial. Sows were allotted to 1 of 2 treatments in a completely randomized design by their body weight, backfat thickness, parity and alive litter weight. One of treatments was dry feeding and the other was liquid feeding (water to feed ratio, 1:1). Experimental diets contained 3265 kcal ME/kg, 12.6 % CP, 5.76 % EE, 1.09 % total lysine, 0.25 % total methionine, as fed basis. Dry feeding treatment had high body weight loss rather than liquid feeding treatment (P = 0.04). Dry feeding treatment had tendency to increase litter weight at 21d of lactation (P = 0.06) and litter weight gain (P = 0.04) during lactation period (0-3 week). Sows fed dry feeding method made milk containing high content of casein and total solid rather than sows fed liquid feeding method (P = 0.04). In addition, dry feeding treatment had tendency to higher content of milk fat, protein and solid not fat on 21d of lactation (P = 0.07). Sows fed dry feeding type also showed higher milk energy content in milk of 21d lactation (P = 0.05). Furthermore, liquid feeding treatment showed high occurrence in feed waste during lactation period (P sows under high temperature environment like lactating barn.

    Humpback whales, Megaptera novaeangliae, breeding off la Reunion Island (Indian Ocean) undergo large-scale seasonal migrations between summer feeding grounds near Antarctica and their reproductive winter grounds in the Indian Ocean. The main scope of the current study was to investigate chemical exposure of humpback whales breeding in the Indian Ocean by providing the first published data on this breeding stock concerning persistent organic pollutants (POPs), namely polychlorinated biphenyls (PCBs), hexachlorobenzene (HCB), hexachlorocyclohexanes (HCHs), DDT and its metabolites (DDTs), chlordane compounds (CHLs), polybrominated diphenyl ethers (PBDEs), and methoxylated PBDEs (MeO-PBDEs). Analyses of stable isotopes δ(13)C and δ(15)N in skin resulted in further insight in their feeding ecology, which was in agreement with a diet focused mainly on low trophic level prey species, such as krill from Antarctica. POPs were measured in all humpback whales in the order of HCB > DDTs > CHLs > HCHs > PCBs > PBDEs > MeO-BDEs. HCB (median: 24 ng g(-1) lw) and DDTs (median: 7.7 ng g(-1) lw) were the predominant compounds in all whale biopsies. Among DDT compounds, p,p'-DDE was the major organohalogenated pollutant, reflecting its long-term accumulation in humpback whales. Significantly lower concentrations of HCB and DDTs were found in females than in males (p  0.05). Differences in the HCB and DDTs suggested gender-specific transfer of some compounds to the offspring. POP concentrations were lower than previously reported results for humpback whales sampled near the Antarctic Peninsula, suggesting potential influence of their nutritional status and may indicate different exposures of the whales according to their feeding zones. Further investigations are required to assess exposure of southern humpback whales throughout their feeding zones. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Full Text Available Abstract Background Chile has experienced the nutritional transition due to both social and economic progress. As a consequence, higher rates of overweight and obesity have been observed in children. In western countries, researchers have tried to determine pathways by which parents influence their children's eating behavior; up to now findings have been inconsistent. The objective of this study was to evaluate the cross-sectional and retrospective relationship between maternal attitudes and child-feeding practices and children's weight status in children who had been subject of an obesity prevention intervention for two years. Methods In 2006, for a cross-sectional study, a random sample of 232 children (125 girls, mean age 11.91 ± 1.56 y and 107 boys mean age 11.98 ± 1.51 y was selected from three primary schools from a small city called Casablanca. Weight and height were determined to assess their nutritional status, using body mass index (BMI z scores. Child-feeding practices and attitudes were determined cross-sectionally in 2006, using the Child Feeding Questionnaire (CFQ. To analyze the relationship between trends in weight change and child-feeding practices and attitudes, BMI z scores of all the 232 children in 2003 were used. Results Cross-sectionally, mothers of overweight children were significantly more concerned (P z score was positively correlated with concern for child's weight (r = 0.28, P z score between age 9 and 12 was positively correlated with concern for child's weight, but only in boys (r = 0.21, P z score at age 12. Conclusion Mothers of overweight children were more concerned with their children's weight; this indicated the Western negative attitude towards childhood overweight. None of the child-feeding practices were significantly correlated with a change in BMI z score.

    Previous research suggests that parental report of children's feeding corresponds with their child's nutritional intake (Cooke et al., 2006; Ekstein et al., 2010). The current study aimed to determine whether there is a relationship between parental report of children's feeding problems and their child's nutritional intake in a non-clinical population and, in addition, to establish whether parental anxiety (Cooke et al., 2003) can predict whether parental report of feeding problems correspond with the child's intake. Sixty-one parents of children aged two to seven years completed the parent report measure; the Behavioural Paediatric Feeding Assessment Scale as well as a food diary detailing their child's intake, which was analysed using CompEAT nutritional software. They also completed the anxiety subscale of the Hospital Anxiety and Depression Scale. Previous findings of an association between parent report of feeding problems and child's intake (Cooke et al., 2006) were not replicated. However, an association was found between parents' anxiety and their reports of feeding problems. Parental anxiety was also found to independently predict whether parent report of feeding problems matched the child's intake. Findings highlight the importance of a multifactorial approach to understanding childhood feeding difficulties. This requires replication with a clinical sample.

  18. Investigation into the Flow Properties of Coarse Solid Fuels for Use in Industrial Feed Systems

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available Material feeding and handling systems have been cited as one of the most common causes of process downtime where thermochemical conversion processes are concerned. New and emerging fuels come in a variety of forms, and if such fuels are to be deployed widely it is imperative that material feeding and handling systems are designed appropriately. This study proposes an approach for designing material feeding and handling systems for use with coarse solid fuels. The data obtained from this study indicates particle size to be one of the key issues affecting the flowability of bulk solids further to the uniformity in particle shape. Coarse bulk solid samples were shown to flow more freely than their milled and pulverised counterparts, generating higher degrees of flowability. The results from this study were also applied to a new feed system used for feeding solid fuels to high pressure processes named the Hydraulic Lock Hopper. In this study the Hydraulic Lock Hopper demonstrated the feeding of wood pellets, torrefied spruce pellets, and ground anthracite coal grains against a pressure of 25 barg in two modes of operation. Energy savings compared to conventional lock hopper systems were recorded in the region of 80%.

    2006-09-01

    This study aimed to compare maternal and paternal feeding practices with male and female children and examine the influence of the gender of both the parent and child on the relationship between parental unhealthy eating attitudes and controlling feeding practices. One hundred and eighty-eight participants (94 co-habiting mother-father dyads, mean age 36.4 years, SD=4.9), who were the parents of 46 male and 48 female children (mean age 37.7 months, SD=12.7) completed measures of unhealthy eating attitudes and feeding practices. Mothers and fathers differed significantly in their reports of unhealthy eating attitudes but not in their restrictive or pressurising feeding practices. Mothers reported greater perceived feeding responsibility and greater monitoring of their children's food intake than fathers. Bulimia scores were correlated with controlling feeding practices in mothers of girls but not boys. Fathers' body dissatisfaction was correlated with monitoring of sons' but not daughters' food intake. These findings suggest that parental extrapolation of weight concerns may be more likely to occur within mother-daughter and father-son relationships.

    2015-01-01

    Concerns have been expressed regarding the safety of using biotechnology derived feeds in diets of livestock animals and in regard to human consumption of products from species fed transgenic crops. As a consequence, a large number of poultry nutrition studies have been conducted to evaluate the wholesomeness of transgenic crops by examining performances of animals during growth or egg laying. Studies also evaluated whether foreign DNA and proteins could be detected in meat, egg, and tissue samples from broiler chickens and laying hens fed diets containing transgenic feeds. In all studies, the conclusions were in agreement that the transgenic crops provided comparable performance, carcass and egg yields, and meat and egg composition, when compared with conventional grains. Moreover, it was demonstrated that transgenic proteins and DNA present in livestock feeds are not detectable in food products derived from these animals, using the most sensitive detection methods available, confirming that they are rapidly degraded by normal digestive processes. The lack of significant differences were a result of the similarity in nutrient composition of the genetically modified feeds and lack of differences in intake and digestibility, while there were no evidences that the differences reported for performance response variables and carcass measurements between treatment groups were attributable to the presence of the transgenic gene and protein in the biotechnology derived plants. Results demonstrated that genetically modified feeds are substantially equivalent and they result as safe as existing conventional feeds.

    Many factors affect how people perceive the world and their environment, and how such perceptions affect lifestyle decisions, yet the relationship between personal perceptions about environmental hazards and diet is rarely examined. In this study, environmental concerns on a local and global scale were examined, along with dietary patterns, to determine if there were associations and age-related differences. The hypothesis that concerns about water pollution might be reflected in choices about seafood consumption was examined. Many aspects of dietary choices varied significantly by age, including (1) younger people ate more "fast food" than others, (2) subjects aged 22-32 yr ate more meals in restaurants than older or younger people, (3) older individuals drank more tea than younger subjects, while younger people drank more soda than older people, and (4) there were few significant differences in total fish and shellfish meals, although young people ate more meals of other types of meat. Individuals who rated their health the best reported significantly fewer seafood meals than others. People who listed pollution as the major environmental problem did not consume seafood less often than others. While pollution was listed as the most important environmental problem globally, people distinguished between air and water pollution only for Singapore. Although Singapore, with its rapidly expanding economy, has reason to be concerned about both water and air pollution, only 14% of those listing pollution as the main Singapore environmental problem mentioned "water pollution." Singapore has been able to take measures to reduce water pollution from internal sources. Respondents considered air pollution a greater problem, perhaps reflecting recent haze disasters from deliberately set forest fires in Indonesia, which are beyond the direct control of Singapore or Singaporeans.

  2. Robotic milking: Feeding strategies and economic returns.

    Bach, Alex; Cabrera, Victor

    2017-02-16

    Cows in herds equipped with conventional milking parlors follow a structured, consistent, and social milking and feeding routine. Furthermore, in most cases cows in conventional herds receive all their nutrients from a total mixed ration, whereas in herds equipped with robotic or automatic milking systems (AMS) a fraction of their nutrients is provided during milking, mainly as a means to attract cows to the milking system. In this regards, AMS present both a challenge and an opportunity for feeding cows. The main challenge resides in maintaining a minimum and relatively constant milking frequency in AMS. However, milking frequency is dependent on many factors, including the social structure of the herd, the farm layout design, the type of traffic imposed to cows, the type of flooring, the health status of the cow (especially lameness, but also mastitis, metritis, among others), the stage of lactation, the parity, and the type of ration fed at the feed bunk and the concentrate offered in the AMS. Uneven milk frequency has been associated with milk losses and increased risk of mastitis, but most importantly it is a lost opportunity for milking the cow and generating profit. On the other hand, the opportunity from AMS resides in the possibility of milking more frequently and feeding cows more precisely or more closely to their nutrient needs on an individual basis, potentially resulting in a more profitable production system. But, feeding cows in the parlor or AMS has many challenges. On one side, feeding starchy, highly palatable ingredients in large amounts may upset rumen fermentation or alter feeding behavior after milking, whereas feeding high-fiber concentrates may compromise total energy intake and limit milking performance. Nevertheless, AMS (and some milking parlors, especially rotary ones) offer the possibility of feeding the cows to their estimated individual nutrient needs by combining different feeds on real time with the aim of maximizing profits rather

    2004-01-01

    Obesity in adolescence has increased significantly over the past 30-40 years and a recent international comparison study (13 European countries, Israel and the US) showed that the highest prevalence in adolescents was found in the US (12.6% in 13 year old boys, 10.8% in girls; 13.9% in 15 year old boys and 15.1% in 15 year old girls) and the lowest in Lithuania. This increase in adolescence is a public health concern, because most obese adolescents continue their obesity into adulthood with serious risk for chronic disease. Focus should therefore be on prevention programs that increase healthier patterns of lifestyle and physical activity.

    The safety of the food supply is a subject of intense interest to consumers, particularly as a result of large scale outbreaks that involve hundreds and sometimes thousands of consumers. During the last decade this concern about food safety has expanded to include the diets of companion animals as a result of several incidences of chemical toxicities and infectious disease transmission. This has led to increased research into the causes and controls for these hazards for both companion animals and their owners. The following summary provides an introduction to the issues, challenges, and new tools being developed to ensure that commercial pet foods are both nutritious and safe.

    2017-01-01

    A series of test activities has raised some concerns about the generation of orbital debris caused by failures of composite overwrapped pressure vessels (COPVs). These tests have indicated that a large number of composite fragments can be produced by either pressure burst failures or by high-speed impacts. A review of prior high-speed tests with COPV indicates that other tests have produced large numbers of composite fragments. As was the case with the test referenced here, the tests tended to produce a large number of small composite fragments with relatively low velocities induced by the impact and or gas expansion.

    Full Text Available Introduction: Feed is a potential and major source for introducing Salmonella into the animal-derived food chain. This is given special attention in the European Union (EU efforts to minimize human food-borne Salmonella infections from animal-derived food. The objective of this study was to estimate the total extra cost for preventing Salmonella contamination of feed above those measures required to produce commercial feed according to EU regulation (EC No 183/2005. The study was carried out in Sweden, a country where Salmonella infections in food-producing animals from feed have largely been eliminated. Methods: On the initiative and leadership of the competent authority, the different steps of feed production associated with control of Salmonella contamination were identified. Representatives for the major feed producers operating in the Swedish market then independently estimated the annual mean costs during the years 2009 and 2010. The feed producers had no known incentives to underestimate the costs. Results and discussion: The total cost for achieving a Salmonella-safe compound feed, when such a control is established, was estimated at 1.8–2.3 € per tonne of feed. Of that cost, 25% relates to the prevention of Salmonella contaminated high-risk vegetable feed materials (mainly soybean meal and rapeseed meal from entering feed mills, and 75% for measures within the feed mills. Based on the feed formulations applied, those costs in relation to the farmers’ 2012 price for compound feed were almost equal for broilers and dairy cows (0.7%. Due to less use of protein concentrate to fatten pigs, the costs were lower (0.6%. These limited costs suggest that previous recommendations to enforce a Salmonella-negative policy for animal feed are realistic and economically feasible to prevent a dissemination of the pathogen to animal herds, their environment, and potentially to human food products.

    Despite the importance of per-capita feeding rates for mosquito-borne transmission dynamics, the relationship between host aggregation and per-capita feeding rates remains poorly characterized. We conducted indoor experiments to investigate how Culex quinquefasciatus (Say) mosquitoes distribute their blood feeding on variably aggregated domestic chickens (Callus gallus domesticus L.) (one chicken vs. a flock of seven to nine birds). Mosquitoes were always more likely to feed on the larger chicken group; yet, the single chicken tended to be fed on at a higher per-capita rate. When 10 chickens were available the feeding intensity was 4.5 times higher for the single chicken compared with the flock. We conclude that more highly aggregated hosts may experience lower exposure to mosquito bites than less aggregated hosts.

    Rate of gain and feed efficiency are very important traits in most breeding programs for growing farm animals. Rate of gain (GAIN) is usually expressed over a certain age period and feed efficiency is often expressed as residual feed intake (RFI), defined as observed feed intake (FI) minus expected...... feed intake based on live weight (WGT) and GAIN. In any case the basic traits recorded are always WGT and FI and other the traits are derived from these records. A bivariate longitudinal random regression model were employed on 9284 individual longitudinal records of WGT and FI from 2827 bulls of six...

    Water is a substance essential for life. It creates the environment of our body, keeps it's homeostasis, enables every biochemical reaction and metabolic processes in human organism. Maternal hydratation is essential for homeostasis of two organisms and drinking water influences the amniotic fluid volume, fetal well-being and removes toxic metabolic products. The chemical contaminants of drinking water and products of it's chlorination and ozonization could be responsible for spontaneous abortion, birth defects and perinatal complications. Therefore it is recommended to drink natural mineral water for women in reproductive age.

    Tench (Tinca tinca) has been described as a strictly nocturnal species whose locomotor activity rhythms, albeit strongly synchronised by light, have an endogenous nature. Aside from light, a number of other environmental factors, such as mealtime, can act as circadian system synchronisers in fish; however, there is a scarcity of information on tench feeding rhythms. This study describes daily self-feeding rhythms in tench, and analyses the role of feeding time on synchronisation of locomotor activity rhythms. Tench were able to operate string sensor-activated self-feeders, and they displayed a strictly nocturnal behavior, both under indoor and outdoor conditions. Locomotor activity remained strictly nocturnal irrespective of whether tench were fed only during the scotophase (D-feeding) or the photophase (L-feeding). However, no statistically significant differences were detected between both groups in terms of food intake or growth performance. Furthermore, unlike L-feeding, D-feeding elicited a clear anticipatory activity (FAA). When tench were given the possibility of feeding at both times of the day, they showed a clear preference for D-feeding. Finally, in fish exposed to constant darkness (DD), feeding time acted as a true zeitgeber and FAA was observed. When animals were fasted under DD conditions, locomotor activity free-run and 6 out of 12 individuals yielded significant results in the periodogram analysis. Under DD, fish resynchronised when regular food was resumed, with some tench displaying FAA. The obtained results indicated the existence of a feeding-entrainable oscillator (FEO) in tench.

    The aim of the study was to test Thymi herba (1.66% v/w essential oil with 39% p-cymene and 32% thymol) in the rearing period of piglets as feed additive. Therefore, two feeding trials were performed with piglet groups ranging from 17 to 22 animals each. Either 10 g of Thymi herba/kg feed (Thymi herba group), 10 mg flavophospholipol/kg feed (flavophospholipol group) or nothing (control group) was added to the animals' feed. No significant differences in the performance parameter daily weight gain among any groups were recorded. No differences concerning feed efficiency or isolation of haemolytic E. coli serotypes were shown. In addition, the antibacterial activity of the essential oil of Thymi herba against 39 haemolytic E. coli isolates from the same weaners was investigated in vitro by disk diffusion, minimum inhibitory concentration and bactericidal concentration testing. In contrast to the feeding results, the essential oil of the thyme batch fed showed antibacterial activity against all haemolytic E. coli investigated. This interesting antibacterial potential of Thymi herba prompts further investigations as to its value as feed additive.

    Full Text Available introduction. Natural breastfeeding is the only proper way to feed newborns and infants because it ensures their proper development. Breastfeeding enhances health and protects against the development of many diseases in childhood and adulthood. The primary benefits of breastfeeding include reduced incidences of infection in the respiratory system as well as a reduction in gastrointestinal and systemic infections. The benefits of breastfeeding also include decreased inflammation and improved immunity to disease in the infant. Further benefits of breastfeeding are reduced incidences of type 1 diabetes, Crohn’s disease, and rheumatoid arthritis. objective.

    Between 2012 and 2014, 2528 feed ingredient and complete feed samples were collected from central China. Numbers of 2083, 255 and 190 samples were analysed for aflatoxin B1 (AFB1), zearalenone (ZEN) and deoxynivalenol (DON), respectively, by high-performance liquid chromatography in combination with UV or fluorescence detection. The incidence rates of AFB1, ZEN and DON contamination of feed ingredients and complete feeds were 33.9%, 90.2% and 77.4%, respectively. The percentage of positive samples for AFB1 ranged from 13.1% to 97.1%. Cottonseed meal presented the most serious contamination by AFB1. ZEN and DON contamination levels of feeds ranged from 50% to 100%, indicating serious contamination over the studied 3-year period. This study demonstrates that AFB1, ZEN and DON contamination of feeds in central China is serious and differs over the years. Feeds are mostly contaminated with ZEN, followed by DON and AFB1.

    Porcine Epidemic Diarrhea Virus (PEDV) was the first virus of wide scale concern to be linked to possible transmission by livestock feed or ingredients. Measures to exclude pathogens, prevent cross-contamination, and actively reduce the pathogenic load of feed and ingredients are being developed. However, research thus far has focused on the role of chemicals or thermal treatment to reduce the RNA in the actual feedstuffs, and has not addressed potential residual contamination within the manufacturing facility that may lead to continuous contamination of finished feeds. The purpose of this experiment was to evaluate the use of a standardized protocol to sanitize an animal feed manufacturing facility contaminated with PEDV. Environmental swabs were collected throughout the facility during the manufacturing of a swine diet inoculated with PEDV. To monitor facility contamination of the virus, swabs were collected at: 1) baseline prior to inoculation, 2) after production of the inoculated feed, 3) after application of a quaternary ammonium-glutaraldehyde blend cleaner, 4) after application of a sodium hypochlorite sanitizing solution, and 5) after facility heat-up to 60°C for 48 hours. Decontamination step, surface, type, zone and their interactions were all found to impact the quantity of detectable PEDV RNA (P production of the contaminated feed. Additionally, the majority of samples collected from non-direct feed contact surfaces were also positive for PEDV RNA after the production of the contaminated feed, emphasizing the potential role dust plays in cross-contamination of pathogen throughout a manufacturing facility. Application of the cleaner, sanitizer, and heat were effective at reducing PEDV genomic material (P < 0.05), but did not completely eliminate it.

    The disposal of food waste is a large environmental problem. In the United Kingdom (UK), approximately 15 million tonnes of food are wasted each year, mostly disposed of in landfill, via composting, or anaerobic digestion (AD). European Union (EU) guidelines state that food waste should preferentially be used as animal feed though for most food waste this practice is currently illegal, because of disease control concerns. Interest in the potential diversion of food waste for animal feed is however growing, with a number of East Asian states offering working examples of safe food waste recycling - based on tight regulation and rendering food waste safe through heat treatment. This study investigates the potential benefits of diverting food waste for pig feed in the UK. A hybrid, consequential life cycle assessment (LCA) was conducted to compare the environmental and health impacts of four technologies for food waste processing: two technologies of South Korean style-animal feed production (as a wet pig feed and a dry pig feed) were compared with two widespread UK disposal technologies: AD and composting. Results of 14 mid-point impact categories show that the processing of food waste as a wet pig feed and a dry pig feed have the best and second-best scores, respectively, for 13/14 and 12/14 environmental and health impacts. The low impact of food waste feed stems in large part from its substitution of conventional feed, the production of which has substantial environmental and health impacts. While the re-legalisation of the use of food waste as pig feed could offer environmental and public health benefits, this will require support from policy makers, the public, and the pig industry, as well as investment in separated food waste collection which currently occurs in only a minority of regions.

    Very low birth weight (VLBW) infants have difficulty transitioning to independent oral feeding, be they breast- or bottle-feeding. We developed a 'self-paced' feeding system that eliminates the natural presence of the positive hydrostatic pressure and internal vacuum build-up within a bottle during feeding. Such system enhanced these infants' oral feeding performance as monitored by overall transfer (OT; % ml taken/ml prescribed), rate of transfer (RT; ml/min over an entire feeding). This study hypothesizes that the improvements observed in these infants resulted from their ability to use more mature oral feeding skills (OFS). 'Feeders and growers' born between 26-29 weeks gestation were assigned to a control or experimental group fed with a standard or self-paced bottle, respectively. They were monitored when taking 1-2 and 6-8 oral feedings/day. OFS was monitored using our recently published non-invasive assessment scale that identifies 4 maturity levels based on infants' RT and proficiency (PRO; % ml taken during the first 5 min of a feeding/total ml prescribed) during bottle feeding. Infants oral feeding outcomes, i.e., OT, RT, PRO, and OFS maturity levels were enhanced in infants fed with the self-paced vs. standard bottle (p ≤ 0.007). The improved oral feeding performance of VLBW infants correlated with enhanced OFS. This study is a first to recognize that VLBW infants' true OFS are more mature than recognized. We speculate that the physical properties inherent to standard bottles that are eliminated with the self-paced system interfere with the display of their true oral feeding potential thereby hindering their overall oral feeding performance.

    Full Text Available Purpose. To review scientific sources on the use of feed yeast preparations in feeding of sturgeon species (Acipenserinae. Findings. The review of scientific works demonstrated that feed yeast in the feeding of sturgeons have been used as a source of vitamins and complete protein, the nutritional value of which is significantly higher than in the proteins of plant origin and are similar to the proteins of animal origin. In addition, a unit of yeast protein mass is significantly lower than in the feeds of animal origin. Moreover, based on the content of B group vitamins, feed yeast produced from the grain-potato spent wash exceed fish meal and meat-and-bone meal. The article highlights the peculiarities of the technological process of the production of different feed yeast species, amino acid and fatty acid composition of their preparations, basic physical and chemical parameters of their composition. The examples of feed yeast formulas for sturgeon species based on feed yeast preparations are presented. It was shown that sturgeon species, especially on early stages of their ontogenesis, could effectively use the feed yeast nucleotides. Thus, the latters can be an effective substitute of live zooplanktonic organisms. While the production of some feed yeast preparations (paprin, eprin was stopped in 1990s due to a number of social-economic reasons, the works on the creation of their full analogues was continued later. Currently, the trends of the development of world aquaculture anticipates the return to the use of yeast in fish feeding. Therefore, the interest of the agrarians of Ukraine in yeast lately increased and their use in agricultural sector increased by 2-2.5 times. Practical value. The array of the summarized information will be important for scientists who study the peculiarities of feeding of sturgeon species, because the data about the use of yeast as sources of complete protein in fish feeds is important in a constant search for the

    Residual feed intake (RFI) is a measure of an individual's efficiency in utilizing feed for maintenance and production during growth or lactation, and is defined as the difference between the actual and predicted feed intake of that individual. The objective of this study was to relate RFI to feeding behavior and to identify behavioral differences between animals with divergent RFI. The intakes and body weight (BW) of 1,049 growing dairy heifers (aged 5-9 mo; 195 ± 25.8 kg of BW) in 5 cohorts were measured for 42 to 49 d to ascertain individual RFI. Animals were housed in an outdoor feeding facility comprising 28 pens, each with 8 animals and 1 feeder per pen, and were fed a dried, cubed alfalfa diet. This forage diet was chosen because most dairy cows in New Zealand are grazed on ryegrass-dominant pastures, without grain or concentrates. An electronic feed monitoring system measured the intake and feeding behavior of individuals. Feeding behavior was summarized as daily intake, daily feeding duration, meal frequency, feeding rate, meal size, meal duration, and temporal feeding patterns. The RFI was moderately to strongly correlated with intake in all cohorts (r=0.54-0.74), indicating that efficient animals ate less than inefficient animals, but relationships with feeding behavior traits (meal frequency, feeding duration, and feeding rate) were weak (r=0.14-0.26), indicating that feeding behavior cannot reliably predict RFI in growing dairy heifers. Comparison of the extremes of RFI (10% most and 10% least efficient) demonstrated similar BW and average daily gain for both groups, but efficient animals ate less; had fewer, longer meals; shorter daily feeding duration; and ate more slowly than the least-efficient animals. These groups also differed in their feeding patterns over 24h, with the most efficient animals eating less and having fewer meals during daylight (0600 to 2100 h), especially during the afternoon (1200 to 1800 h), but ate for a longer time during

    Full Text Available Background. WHO and UNICEF recommend “to encourage breastfeeding on demand of the child” in the paragraph 8 of Declaration. This is the recommendation for each institution that provides obstetrical services and follow-up of a newborn. But after 5–6 months of breastfeeding on demand it cannot be declared. At the child’s growth all the organs and systems of the kid are forming. And what was natural in the neonatal period may not be mechanically taken against the child of 3 months old. This is caused by special needs of a child for feeding, sleep duration; also it is less time for nap and more for activity in different ages. Therefore, the term free feeding on demand of the child often comes to casuistic when 3–4 month baby gets breastfeeding up to 8–9 times per day on demand. A three-year child who has been on free breastfeeding for a long time (more than 6 months refuses any food, but breast milk. The purpose of the study was to clarify the situation concerning baby-led breastfeeding on demand in infants according to questionnaires. Materials and methods. There were analyzed questionnaires of mothers who have children aged under one year in different areas of the city of Dnipro (n = 248 questionnaires. Results. According to the survey results baby-led breastfeeding until 6 months occurred in 48 % of cases, more than 6 months in 29.6 % of cases, to one year or more in 18.4 %. It is interesting that today late (7 months and older breastfeeding takes place. Often it becomes a chaotic feeding excluding major age-related anatomical and physiological characteristics of the digestive tract that dictate the rules for weaning needs. Conclusions. The researches of the baby-led breastfeeding showed the problems and consequences that accompany it, namely relatively late complementary feeding in infants on free breastfeeding, chaotic feeding without taking into account the basic age needs of infants.

    Gastroenteric tube feeding plays a major role in the management of patients with poor voluntary intake, chronic neurological or mechanical dysphagia or gut dysfunction, and patients who are critically ill. However, despite the benefits and widespread use of enteral tube feeding, some patients experience complications. This review aims to discuss and compare current knowledge regarding the clinical application of enteral tube feeding, together with associated complications and special aspects. We conducted an extensive literature search on PubMed, Embase and Medline using index terms relating to enteral access, enteral feeding/nutrition, tube feeding, percutaneous endoscopic gastrostomy/jejunostomy, endoscopic nasoenteric tube, nasogastric tube, and refeeding syndrome. The literature showed common routes of enteral access to include nasoenteral tube, gastrostomy and jejunostomy, while complications fall into four major categories: mechanical, e.g., tube blockage or removal; gastrointestinal, e.g., diarrhea; infectious e.g., aspiration pneumonia, tube site infection; and metabolic, e.g., refeeding syndrome, hyperglycemia. Although the type and frequency of complications arising from tube feeding vary considerably according to the chosen access route, gastrointestinal complications are without doubt the most common. Complications associated with enteral tube feeding can be reduced by careful observance of guidelines, including those related to food composition, administration rate, portion size, food temperature and patient supervision.

    Full Text Available Despite the availability of a national consensus document describing in detail modern approaches to feeding infants, pediatricians keep on giving most diverse recommendations on the time of supplemental feeding introduction. The article presents a brief historical review, as well the modern view on the issue of introduction of supplemental feeding to children. In the previous century, it was common both in Russia and most European countries to introduce supplemental feeding to children at the age of 2 or even 1.5 months. In 2002, the World Health Organization put forward an initiative in support of breastfeeding and recommended not to introduce supplemental feeding before the age of 6 months. A certain “golden mean” has apparently been achieved on the basis of results of studies and a longterm discussion among the specialists in feeding from different countries — all scientific communities and national recommendations of most countries define the optimal age for supplemental feeding introduction as “from 4 (completed months to 6 (completed months” with certain individual approach.

    Full Text Available An outstanding feature of poultry production that provides animal protein yield for human feeding is its short production cycle. This characteristic has a linear relationship with waste production. Increasing the inclusion of this residue in diets in the near future is desirable in step with the growth of poultry production since it offers a better environmental and nutritional alternative to current methods. We evaluated the effects on the performance and carcass characteristics of broiler chickens produced by the inclusion of poultry offal meal (POM in their feed. Treatments consisted of a control diet (corn, Zea mays and soybean, Glycine max and four diets with inclusion of 30, 60, 90 and 120 g kg-1 of POM. The diets were formulated based on the level of digestible amino acid once categorized as isocalcic, isophosphoric, isosodic, isoenergetic and isonutritive for protein, methionine+cystine, lysine and threonine. The feed's electrolytes were corrected so that each diet had the same electrolytic balance. The variables analyzed were feed intake, weight gain, feed conversion ratio, body weight, carcass yield, chicken cut yield and abdominal fat. Feed intake was not affected by the quantities of POM added. The weight gain, feed conversion, carcass yield and noble cuts presented quadratic responses to the treatments. Abdominal fat increased linearly. The performance of the poultry, and carcass characteristics were maximized by the inclusion of 53 and 65 g kg-1, respectively, of POM in the diet, and the inclusion of 120 g kg-1 of POM provided greater disposition of abdominal fat.

This study explores the possibility of combining the prebiotics ability of milk whey and sprouting grains with feed probiotic attributes of microbe to enhance gut health of animals and digestibility of the feed. Twelve variants of products were tested in the study using the microbial and physical-chemical approaches. All the assays showed high count of microorganism and high content of reducing sugar. The results of investigation indicate that selected feed additive show high quality. An additional point is that it contains useful organic acids (lactic, acetic and propionic acids and 2,1×109 colony-forming unit of probiotics microorganism that hold the concentration for 4 months. There are not yeast, must, coliform bacteria and Staphylococcus aureus in the developed functional feed product. It contributes to the normalization of the microflora of the gastrointestinal tract of animal, suppression of conditionally pathogenic and putrefactive microflora. The elaborated feed component will help to provide combined feed companies with accessible high-quality raw material

    An abrasive water-jet cutting process is one in which water pressure is raised to a very high pressure and forced through a very small orifice to form a very thin high speed jet beam. This thin jet beam is then directed through a chamber and then fed into a secondary nozzle, or mixing tube. During this process, a vacuum is generated in the chamber, and garnet abrasives and air are pulled into the chamber, through an abrasive feed tube, and mixes with this high speed stream of water. Because of the restrictions introduced by the abrasive feed tube geometry, a vacuum gradient is generated along the tube. Although this phenomenon has been recognized and utilized as a way to monitor nozzle condition and abrasive flowing conditions, yet, until now, conditions inside the abrasive feed line have not been completely understood. A possible reason is that conditions inside the abrasive feed line are complicated. Not only compressible flow but also multi-phase, multi-component flow has been involved in inside of abrasive feed tube. This paper explored various aspects of the vacuum creation process in both the mixing chamber and the abrasive feed tube. Based on an experimental exploration, an analytical framework is presented to allow theoretical calculations of vacuum conditions in the abrasive feed tube.

    A dielectric rod feed with a special radiation pattern of a tabletop form used for the compact range reflector is developed and analyzed. Application of this feed increases the size of the compact range quiet zone generated by the reflector. The feed consists of the dielectric rod made of polystyren, the rod is inserted into the circular waveguide with a corrugated flange. The waveguide is excited by the H11-mode. The rod is covered by the textolite biconical bushing and has a fluoroplastic insert in the vicinity of the bushing. Mathematical modeling was used to obtain the parameters of the feed for the optimal tabletop form of the radiation pattern. The problem of the electromagnetic radiation was solved for metal-dielectric bodies of rotation by method of integral equations with further solving of the problem of the synthesis for feed parameters. The dielectric rod feed was fabricated for the X-frequency range. Feed amplitude and phase patterns were measured in the frequency range 8.2-12.5 GHz. Presented re...

    Agile methods have appeared as an attractive alternative to conventional methodologies. These methods try to reduce the time to market and, indirectly, the cost of the product through flexible development and deep customer involvement. The processes related to requirements have been extensively studied in literature, in most cases in the frame of conventional methods. However, conclusions of conventional methodologies could not be necessarily valid for Agile; in some issues, conventional and Agile processes are radically different. As recent surveys report, inadequate project requirements is one of the most conflictive issues in agile approaches and better understanding about this is needed. This paper describes some findings concerning requirements activities in a project developed under an agile methodology. The project intended to evolve an existing product and, therefore, some background information was available. The major difficulties encountered were related to non-functional needs and management of requirements dependencies.

  14. Caffeinated alcohol beverages: a public health concern.

    Attwood, Angela S

    2012-01-01

    Consumption of alcohol mixed with caffeinated energy drinks is becoming popular, and the number of pre-mixed caffeinated alcohol products on the worldwide market is increasing. There is public health concern and even occasional legal restriction relating to these drinks, due to associations with increased intoxication and harms. The precise nature and degree of the pharmacological relationship between caffeine and alcohol is not yet elucidated, but it is proposed that caffeine attenuates the sedative effects of alcohol intoxication while leaving motor and cognitive impairment unaffected. This creates a potentially precarious scenario for users who may underestimate their level of intoxication and impairment. While legislation in some countries has restricted production or marketing of pre-mixed products, many individuals mix their own energy drink-alcohol 'cocktails'. Wider dissemination of the risks might help balance marketing strategies that over-emphasize putative positive effects.

    Metzler, Theodore A; Barnes, Susan J

    2014-01-01

    The three dialogues in this contribution concern 21st century application of life-like robots in the care of older adults. They depict conversations set in the near future, involving a philosopher (Dr Phonius) and a nurse (Dr Myloss) who manages care at a large facility for assisted living. In their first dialogue, the speakers discover that their quite different attitudes towards human-robot interaction parallel fundamental differences separating their respective concepts of consciousness. The second dialogue similarly uncovers deeply contrasting notions of personhood that appear to be associated with respective communities of nursing and robotics. The additional key awareness that arises in their final dialogue links applications of life-like robots in the care of older adults with potential transformations in our understandings of ourselves - indeed, in our understandings of the nature of our own humanity. This series of dialogues, therefore, appears to address a topic in nursing philosophy that merits our careful attention.

    Full Text Available Oral cancer is the largest group of cancer that categorizes into the head and neck region and worldwide health problem. Exact cause of oral cancer is unknown. Risk factors for cancer could be varied including Iron deficiency anemi a, are alcohol, tobacco, immunologic susceptibility, gene mutations, epithelial cell growth, suppressor proteins and disease of chemotherapy, such as in cases of lymphoma and leukemia. Role of viruses have also been reported in the etiology. Dietary factor s such as high fat and low fiber may play a role in carcinogenesis in some sites. High incidence of alcoholism is relevant because alcohol intake has been related to an increase risk of developing oral cancer. Other signaling factors have also been propose d to have a role. The paper presents a review on oral cancer, its causes & concern.

  18. C. Linnaeus' ideas concerning retribution and fate

    Directory of Open Access Journals (Sweden)

    K. Rob. V. Wikman

    1967-02-01

    Full Text Available Linnæus' Nemesis divina has been interpreted in different ways. Crucial is its central problem: the ideas of fate and retribution, but these are, in turn, dependent on Linnæus' conception of God and nature and not least on his opinions concerning the unity and coherence of the natural and ethical order of the world. From whatever sources Linnæus may have derived his religious ideas and whatever changes they may have undergone, his religious attitude in face of the works of nature remained unshaken. But Linnæus' religion, as we find it fragmentarily in these literary sources, was entirely undogmatic, untheological and, from a Christian point of view, even heterodox. Partly, this was in accord with his belief in the necessary immanent coherence in the processes of nature and the concomitant idea of the righteous divine order of the world.

    2011-09-01

    Presently, more and more often the medical public is concerned with questions regarding use of textile products intended for multiple application at operating theatres. Such questions have been evoked especially by spreading information on restrictions regarding purchase and us of health care products or medical means made from cotton of intended for multiple application. Based on this information preference is given to significantly more expensive products intended for single-use only. This decision is being reasoned by conditions given by European standard EN 13795 reportedly prohibiting the application of cotton within health care. Since this piece of information is not precise, we would like to sum-up legislative situation within this area.

    2007-01-01

    The uniqueness problem of entire functions concerning weighted sharing was discussed, and the following theorem was proved. Let f and g be two non-constant entire functions, m, n and k three positive integers, and n>2k+4. If Em(1,(f n)(k))= Em(1,(gn)(k)), then either f (z)=c1ecz and g(z)= c2e-cz, or f =tg, where c, c1 and c2 are three constants satisfying (-1)k(c1c2)n(nc)2k=1, and t is a constant satisfying t n=1. The theorem generalizes the result of Fang [Fang ML, Uniqueness and value sharing of entire functions, Computer & Mathematics with Applications, 2002, 44: 823-831].

    This article explores the impact of social media on child development and family health. Why do we allow our children to use social media sites before their privacy policies allow? Why do we let them lie about their ages to use these sites? What is it about technology that lets us bend these rules in a way we would never do in the unplugged world? Gaining insight into the answers to these questions and what is positive and negative about social media and the digital world allows us to talk to families about this world, allay their concerns, and keep children of all age safe when using social media.

    2002-01-01

    Aiming at addressing the ethical aspects concerning nurses' managerial activities, the authors of this work referred to Etzioni and adopted a hospital classification as a reference of organization in which consent is based on the internalization of rules accepted as legitimate. Regarding patients, their need to adapt to medical behavior and hospital rules through internalization is considered to be a result of physicians', nurses' and the hospital's power. However, the authors view that such internalization is naive, without consent, especially by taking into account that most Brazilian patients do not know that they should or should not consent and are used to obeying. Thus, the work focused on nurses' managerial actions, indicating that they must be based on professional values, the Nursing ethical code as well as on the rights of hospitalized patients, thus integrating qualified care guided by respect, free consent and promotion of patients as the protagonists and subjects of care.

    Full Text Available The dynamics of basketball, due to the relatively small court but also to regulations concerning the time of attack, has required finding, by the specialists in this field, new ways of collaboration and specific actions between a certain team’s players. Thus has appeared the 2 on 2 play, with its improved version called pick and roll, which has ”exploded” over the last years, becoming the most important element in many coaches’ strategy. As a description, pick and roll represents the tactic move to which participate the player in possession of the ball and a tall player, which screen him out, temporarily blocking the way of its defender. The purpose of this research is analyzing, in a national champion team, the frequency, the versions and the efficiency of these tactic moves.

  4. HANFORD CHEMICAL VAPORS WORKER CONCERNS & EXPOSURE EVALUATION

    Energy Technology Data Exchange (ETDEWEB)

    ANDERSON, T.J.

    2006-12-20

    Chemical vapor emissions from underground hazardous waste storage tanks on the Hanford site in eastern Washington State are a potential concern because workers enter the tank farms on a regular basis for waste retrievals, equipment maintenance, and surveillance. Tank farm contractors are in the process of retrieving all remaining waste from aging single-shell tanks, some of which date to World War II, and transferring it to newer double-shell tanks. During the waste retrieval process, tank farm workers are potentially exposed to fugitive chemical vapors that can escape from tank headspaces and other emission points. The tanks are known to hold more than 1,500 different species of chemicals, in addition to radionuclides. Exposure assessments have fully characterized the hazards from chemical vapors in half of the tank farms. Extensive sampling and analysis has been done to characterize the chemical properties of hazardous waste and to evaluate potential health hazards of vapors at the ground surface, where workers perform maintenance and waste transfer activities. Worker concerns. risk communication, and exposure assessment are discussed, including evaluation of the potential hazards of complex mixtures of chemical vapors. Concentrations of vapors above occupational exposure limits-(OEL) were detected only at exhaust stacks and passive breather filter outlets. Beyond five feet from the sources, vapors disperse rapidly. No vapors have been measured above 50% of their OELs more than five feet from the source. Vapor controls are focused on limited hazard zones around sources. Further evaluations of vapors include analysis of routes of exposure and thorough analysis of nuisance odors.

  5. The Death of the Concerned Intellectual?

    Directory of Open Access Journals (Sweden)

    Chongyi Feng

    2005-08-01

    Full Text Available This paper offers a definition of the intellectual covering both professional and moral dimensions: An intellectual is a specialist who creates and communicates symbolised knowledge as means of living, and hopefully intervenes in social and political affairs in the name of universal values, truth and justice. "Symbolised knowledge" is used in the definition to avoid the confusion with other forms of knowledge derived from direct personal experience in production and life. The purpose of using "specialist" as the subject term is to exclude those categories such politicians, soldiers and business people who exercise political, military, financial and other forms of power instead of intellectual power in their social function. This paper argues that there are many roles played by intellectuals, and the social location and function of intellectuals can be fundamentally different in different societies. When production and communication of knowledge are taken as the primary concern of intellectuals, ‘the death of the concerned intellectual’ becomes an unwarranted anxiety, because there is no reason to believe that knowledge and truth will no longer be pursued and valued by humankind. Political marginalisation of critical intellectuals, where it is a reality, seems to be caused not so much by the lack of power of intellectuals as by the lack of solidarity among intellectuals to fight for a common cause. The problem lies as much in the lack of enthusiasm among intellectuals to transcend the boundaries of their professional relevance and intervene in broad social and political issues, as in institutional structures consuming too much energy and time of the intellectuals and seducing them to give up their social responsibilities for personal career.

  6. Antifungal Drug Resistance - Concerns for Veterinarians

    2009-10-01

    Full Text Available In the 1990s, there were increased incidences of fungal infectious diseases in human population which might be due to increase in immunosuppressive diseases. But the major concern was increase in prevalence of resistance to antifungal drugs which were reported both in the fungal isolates of human beings and that of animal origin. In both animals and human beings, resistance to antimicrobial agents has important implications for morbidity, mortality and health care costs, because resistant strains are responsible for bulk of infection in animals and human beings, and large number of antimicrobial classes offers more diverse range of resistance mechanisms to study and resistance determinants move into standard well-characterized strains that facilitates the detailed study of molecular mechanisms of resistance in microorganisms. Studies on resistance to antifungal agents has been lagging behind that of antibacterial resistance for several reasons, the foremost reason might be fungal agents were not recognized as important animal and human pathogens, until relatively in recent past. But the initial studies of antifungal drug resistance in the early 1980s, have accumulated a wealth of knowledge concerning the clinical, biochemical, and genetic aspects of this phenomenon. Presently, exploration of the molecular aspects for antifungal drug resistance has been undertaken. Recently, the focus was on several points like developing a more detailed understanding of the mechanisms of antimicrobial resistance, improved methods to detect resistance when it occurs, methods to prevent the emergence and spread of resistance and new antimicrobial options for the treatment of infections caused by resistant organisms.

    Full Text Available Objective: In this study, our aim was to assess and analyze parental concerns by Portuguese District. Methods: The participants were 3842 parents of children between 3 and 10 years old, attending preschool and primary school, from 820 public schools in 18 Portuguese Districts. Parents completed a sociodemographic questionnaire, and a Parental Concerns Scale, composed by 5 subscales, family and school problems; feeding, sleep and physical complaints; preparation; fears; and negative behaviors. Results: Portuguese parents concerned about all the dimensions considered in this study. The highest level of concern was obtained in family and school problems, and the lowest level of concern about their children’s fears. There were significant differences between Districts, parents from Porto and Bragança showed the highest levels of concern. Parents from Coimbra, Évora, Beja e Portalegre, presented the lowest levels of concern. Conclusion: Parental concerns are an aspect of general parenting and must be considered by health professionals to promote healthier parents-children relationships. Geographic differences should be further investigated.

    2015-01-01

    An infant with cleft palate was referred to cleft clinic of the Orthodontic Department. The mother was concerned to feed the child because of the escape of milk from the nose. Intraoral examination revealed a large palatal cleft extending from hard to soft palate involving uvula. The impression was taken and dental cast obtained. A 3 mm soft and afterward a 1 mm hard Bioplast plate was pressed using Biostar device (Scheu-Dental Gmbh, Iserlohn, Germany) on the model. Finally, a hole was prepared on the anterior part to put a thread through it. The infant tolerated the plate immediately and encounters no difficulties during feeding. The inlaying soft Bioplast plates eliminate the risk of tissue irritation, whereas the covering hard Bioplast plate supplies endurance. The fabrication of the clear Bioplast feeding plate is easy and less time-consuming compared with acrylic plates and may be recommended in crowded and overloaded cleft centers.

    Microplastics pollution is a growing global concern that affects all aquatic ecosystems. Microplastics in the environment can be in the form of fibers and/or particles, being the former the most abundant in the marine environment, representing up to 95% of total plastics. The aim of this work was to compare the content of microplastics among intertidal fish with different feeding type. Our results show that omnivorous fish presented a higher amount of microplastic fibers than registered in herbivores and carnivores. Moreover, lower condition factors (K) were found in omnivorous specimens with higher microplastic content. We hypothesized that the type of feeding resulted in different microplastic ingestion, with species with wider range of food sources as omnivores with higher rates. Futures studies carried out to evaluate the biological impacts of microplastics on marine organisms, and microplastics cycling on the marine environment should consider the type of feeding of the studied species.

    This study aims to assess the role that health professional and State policies played in shaping breastfeeding practices and attitudes in Greece during the first half of the 20th century. Original texts were used; including those concerned with breastfeeding traditions, health professionals' attitudes to breastfeeding, infant feeding patterns, partial breastfeeding, artificial feeding and State policies for the promotion of breastfeeding. Content analysis was used and breastfeeding rates were considered. In the first two decades of the 20th century, most Greek women breastfed their children, as advised by other experienced women. In the succeeding decades, health professionals and policy makers wrote books and articles praising breastfeeding albeit stressing the nursing mothers' ignorance of sanitary measures. Many health professionals were influenced by trends in developed countries and advocated novel infant feeding practices. Consequently, full breastfeeding was not promoted.

    Residual feed intake (RFI) is a measure of feed efficiency defined as the difference between observed and predicted feed intake based on average requirements for growth and maintenance. The objective of this study was to evaluate the effect of selection for decreased RFI on feeding behavior traits and to estimate their relationships with RFI. Three data sets from the 4th and 5th generations of a selection experiment with a line selected for reduced RFI (LRFI) and a randomly selected control line (CTRL) were analyzed. Lines were mixed in pens of 16 and evaluated for feeding behavior traits obtained from a single-space electronic feeder over a growing period of ~3 mo before ~115 kg. The following traits were evaluated as averages over the entire test period and over the first and second half of the test period: number of visits per day and hour; occupation time per day, visit, and hour; feed intake (FI) per day, visit, and hour; and FI rate per visit. Models used included fixed effects of line and feeder, covariates of on-test age and FI per day, and random effects of pen, on-test group, sire, and litter. Repeated measures models were used to analyze feeding patterns during the day. The LRFI pigs had significantly less FI per day than CTRL pigs for all 3 data sets. With adjustment for FI per day, line differences of all traits were in the same direction for all 3 data sets but differed in significance and size. Feed intake per visit and hour and visits per day and hour did not differ between lines, but the trend was for LRFI pigs to have fewer visits, in particular during peak eating times. The LRFI pigs had a greater feeding rate and less occupation time per day, visit, and hour than CTRL pigs, but this was not significant for all data sets. Correlations of RFI with FI per day and visit and visits per day were positive. Average daily gain was positively correlated with FI per day and visit and occupation time per visit but negatively correlated with visits per day

    Three dietary compositions and 3 methods of pellet preparation were used in different choice situations to improve our understanding of the factors perceived by broiler chickens in the physical structure of their diet. Within the same visual field, broiler chickens were offered 8 microfeeders containing different pelleted feeds that could be reached from the same position of the bird. Chickens were daily tested during 5-min tests following a 45-min period of feed withdrawal, after adaptation to individual cages and experimental feeders. Two feeds (4 microfeeders/feed in alternate positions) were weighed prior to and after the test. Behavior of the chickens was videotaped during the test to count the number of pecks given to each microfeeder. In a first experiment, 2 feeds of distinct composition were either steam or cold-pelleted. The tests of choice were repeated daily from 22 to 25 and from 35 to 38 d of age on 96 male broiler chickens. Significant preferences were measured from the first test. Similar preferences were measured when chickens received the same choice or alternating choices from one test to another. Differences of feed intake between 2 feeds during 5 min were significantly correlated to differences of number of pecks (R2 = 0.85). In most cases, preferences were established within the first minute of pecking. Steam pellets were significantly preferred to cold pellets for one feed composition but not for the other. Preferences for compositions were consistent whatever the pellet preparation and probably associated with the color of the feeds. A second experiment confirmed that 38-d-old broiler chickens seemed to prefer light colors. Short-term preferences of a chicken for a feed were rather influenced by physical characteristics of feed particles (size, color, hardness) than by the origin of raw materials. Feed pecking may change because of feed composition itself, because of its consequences on color or texture cues, or both.

    2007-07-01

    Full Text Available Abstract Background Infant feeding is a subject of worry in prevention of mother to child transmission (pMTCT programmes in settings where breastfeeding is normative. Nurse-counsellors, expected to counsel HIV-positive women on safer infant feeding methods as defined in national/international guidelines, are faced with a number of challenges. This study aims to explore the experiences and situated concerns of nurses working as infant feeding counsellors to HIV-positive mothers enrolled in pMTCT programmes in the Kilimanjaro region, northern Tanzania. Methods A qualitative study was conducted using in-depth interviews and focus group discussions (FGDs with 25 nurse-counsellors at four pMTCT sites. Interviews were handwritten and FGDs were tape-recorded and transcribed, and the programme Open Code assisted in sorting and structuring the data. Analysis was performed using 'content analysis.' Results The findings revealed a high level of stress and frustration among the nurse-counsellors. They found themselves unable to give qualified and relevant advice to HIV-positive women on how best to feed their infants. They were confused regarding the appropriateness of the feeding options they were expected to advise HIV-positive women to employ, and perceived both exclusive breastfeeding and exclusive replacement feeding as culturally and socially unsuitable. However, most counsellors believed that formula feeding was the right way for an HIV-positive woman to feed her infant. They expressed a lack of confidence in their own knowledge of HIV and infant feeding, as well as in their own skills in assessing a woman's possibilities of adhering to a particular method of feeding. Moreover, the nurses were in general not comfortable in their newly gained role as counsellors and felt that it undermined the authority and trust traditionally vested in nursing as a knowledgeable and caring profession. Conclusion The findings illuminate the immense burden placed on

  3. Operational Philosophy Concerning Manned Spacecraft Cabin Leaks

    DeSimpelaere, Edward

    2011-01-01

    The last thirty years have seen the Space Shuttle as the prime United States spacecraft for manned spaceflight missions. Many lessons have been learned about spacecraft design and operation throughout these years. Over the next few decades, a large increase of manned spaceflight in the commercial sector is expected. This will result in the exposure of commercial crews and passengers to many of the same risks crews of the Space Shuttle have encountered. One of the more dire situations that can be encountered is the loss of pressure in the habitable volume of the spacecraft during on orbit operations. This is referred to as a cabin leak. This paper seeks to establish a general cabin leak response philosophy with the intent of educating future spacecraft designers and operators. After establishing a relative definition for a cabin leak, the paper covers general descriptions of detection equipment, detection methods, and general operational methods for management of a cabin leak. Subsequently, all these items are addressed from the perspective of the Space Shuttle Program, as this will be of the most value to future spacecraft due to similar operating profiles. Emphasis here is placed upon why and how these methods and philosophies have evolved to meet the Space Shuttle s needs. This includes the core ideas of: considerations of maintaining higher cabin pressures vs. lower cabin pressures, the pros and cons of a system designed to feed the leak with gas from pressurized tanks vs. using pressure suits to protect against lower cabin pressures, timeline and consumables constraints, re-entry considerations with leaks of unknown origin, and the impact the International Space Station (ISS) has had to the standard Space Shuttle cabin leak response philosophy.

    2017-01-01

    Responsive feeding is a derivative of responsive parenting that has been applied to infant and young child feeding. With a theoretical basis in the reciprocal interactions between parents and children, responsive feeding is particularly relevant during complementary feeding as young children progress from an exclusively milk-based liquid diet to the family diet and self-feeding. The period of complementary feeding includes multiple developmental changes that may threaten a successful transition and lead to growth and feeding problems. In spite of high rates of global childhood underweight, stunting, overweight, and obesity, and the inclusion of responsive feeding in the World Health Organization's Global Strategy for Infant and Young Child Feeding, there have been few intervention trials of responsive feeding. The aim of this chapter is to examine how parents and young children navigate the progression in feeding, with an emphasis on complementary feeding, and to address the following topics: (1) navigating the progression of feeding development, (2) provision of responsive feeding, (3) preventing or resolving growth and feeding problems, (4) responsive feeding research, and (5) strategies to promote healthy mealtime interactions. To advance responsive feeding research and practice, clarity is needed in both measurement and intervention strategies, guided by the reciprocity between parent and child interactions inherent in the theoretical basis of responsive feeding. © 2017 Nestec Ltd., Vevey/S.

    To accelerate the adoption of these emerging marine hydrokinetic technologies, navigational and environmental issues and concerns must be identified and addressed. As hydrokinetic projects move forward, various stakeholders will need to be engaged; one of the key issues that project proponents face as they engage stakeholders is that many conflicting uses and environmental issues are not well-understood. Much of this lack of understanding comes from a limited understanding of the technologies themselves. To address this issue, in September 2008, RE Vision consulting, LLC, was selected by the Department of Energy, under their market acceleration program, to apply a scenario-based assessment approach to the emerging hydrokinetic technology sector. The goal was to improve understanding of potential environmental and navigation impacts of these technologies and focus stakeholders on the critical issues. To meet this goal, the study established baseline scenarios for wave and tidal power conversion at potential future deployment sites. The scenarios captured variations in technical approaches and deployment scales and thus grounded the analysis in realistic constraints. The work conducted under this award provides an important foundation to other market acceleration activities carried out by the DOE and other stakeholders in this sector. The scenarios were then evaluated using a framework developed by H.T. Harvey & Associates to identify and characterize key environmental concerns and uncertainties. In collaboration with PCCI and the U.S. Coast Guard, navigation issues were assessed and guidelines developed to assure the safe operation of these systems. Finally, the work highlights “next steps” to take to continue development and adoption of marine hydrokinetic energy. Throughout the project, close collaboration with device developers, project developers and regulatory stakeholders was pursued to ensure that assumptions and constraints are realistic.

    New advances in engineering and biomedical technology have enabled recent efforts to capture essential aspects of human physiology in microscale, in-vitro systems. The application of these advances to experimentally model complex processes in an integrated platform - commonly called a 'human-on-a-chip (HOC)' - requires that relevant compartments and parameters be sized correctly relative to each other and to the system as a whole. Empirical observation, theoretical treatments of resource distribution systems and natural experiments can all be used to inform rational design of such a system, but technical and fundamental challenges (e.g. small system blood volumes and context-dependent cell metabolism, respectively) pose substantial, unaddressed obstacles. Here, we put forth two fundamental principles for HOC design: inducing in-vivo-like cellular metabolic rates is necessary and may be accomplished in-vitro by limiting O2 availability and that the effects of increased blood volumes on drug concentration can be mitigated through pharmacokinetics-based treatments of solute distribution. Combining these principles with natural observation and engineering workarounds, we derive a complete set of design criteria for a practically realizable, physiologically faithful, five-organ millionth-scale (× 10(-6)) microfluidic model of the human body.

  7. Cell dialysis by sharp electrodes can cause nonphysiological changes in neuron properties.

    We recorded from lobster and leech neurons with two sharp electrodes filled with solutions often used with these preparations (lobster: 0.6 M K2SO4 or 2.5 M KAc; leech: 4 M KAc), with solutions approximately matching neuron cytoplasm ion concentrations, and with 6.5 M KAc (lobster, leech) and 0.6 M KAc (lobster). We measured membrane potential, input resistance, and transient and sustained depolarization-activated outward current amplitudes in leech and these neuron properties and hyperpolarization-activated current time constant in lobster, every 10 min for 60 min after electrode penetration. Neuron properties varied with electrode fill. For fills with molarities ≥2.5 M, neuron properties also varied strongly with time after electrode penetration. Depending on the property being examined, these variations could be large. In leech, cell size also increased with noncytoplasmic fills. The changes in neuron properties could be due to the ions being injected from the electrodes during current injection. We tested this possibility in lobster with the 2.5 M KAc electrode fill by making measurements only 10 and 60 min after penetration. Neuron properties still changed, although the changes were less extreme. Making measurements every 2 min showed that the time-dependent variations in neuron properties occurred in concert with each other. Neuron property changes with high molarity electrode-fill solutions were great enough to decrease neuron firing strongly. An experiment with (14)C-glucose electrode fill confirmed earlier work showing substantial leak from sharp electrodes. Sharp electrode work should thus be performed with cytoplasm-matched electrode fills.

  8. Theoretic analysis of middle ear gas composition under conditions of nonphysiologic ventilation.

    Science.gov (United States)

    Ostfeld, E J; Silberberg, A

    1992-05-01

    As gas flows in and out of the nasopharynx, the pressure in that region fluctuates. It drops below or rises above atmospheric pressure, which is itself not constant but is subject to changes in altitude and weather. Such pressure changes in the nasopharynx produce a pumping of gas into and out of the middle ear. The net amount of middle ear gas transferred from or to the nasopharynx will, component for component, in steady state exactly equal the amount of middle ear gas transferred to or from the microcirculation by means of diffusional absorption by (or release from) the mucosa. In the case of a permanently patulous eustachian tube, a single parameter, characteristic of the rate of ventilation through the open eustachian tube, is found to determine the gas composition in the middle ear, whereas in the case of a middle ear ventilated by tympanostomy, two rate-of-ventilation parameters, one for gas flow through the ventilation tube and one for flow through a periodically open eustachian tube, determine the steady state gas composition. A high rate of ventilation favors absorption of oxygen and venting of carbon dioxide from the middle ear in both cases.

  9. Fukushima- Ocean Impacts and Public Concerns

    Buesseler, K.

    2015-12-01

    The triple disaster of the March 11, 2011 earthquake, tsunami, and subsequent radiation releases at Fukushima Dai-ichi were unprecedented events for the ocean and society. This presentation will provide an overview of studies of Fukushima radionuclides in the ocean. The radioactive releases from Fukushima will be compared to natural and prior human sources. The fate of cesium is largely determined by its soluble nature in seawater, though uptake in sediments does occur via cesium's association with both detrital particles and biological uptake and sedimentation. Cesium's continued supply from the rivers and ongoing leakages at the nuclear power plants suggests that coastal sediments may remain contaminated for decades to come. Although levels of cesium in the ocean and being released from Fukushima more than four years later are orders of magnitude lower than in 2011, other isotopes such as strontium-90 remain of interest as they are elevated relative to cesium in the groundwater and storage tanks at the reactor site. Across the Pacific, Fukushima cesium is starting to be detectable along the west coast of North America. Although models suggest cesium will be at levels well below those considered of human health concern, the public is worried about the lack of ocean monitoring of Fukushima radionuclides. We addressed these public concerns by creating "Our Radioactive Ocean" a citizen-scientist crowd-funded campaign that provides a sampling kit that can use to sample their favorite beach. Once collected, samples are returned to WHOI for analyses of the isotopes of cesium that allow us to distinguish Fukushima cesium from other sources (http://OurRadioactiveOcean.org ). However to measure the low levels of cesium already in the ocean 20 liter samples are needed. To increase public participation, we will also present results from a new wearable sample collector, the "RadBand" which contains a small amount of cesium selective resin that surfers and swimmers can wear on

  13. Technical inventions that enabled artificial infant feeding.

    Science.gov (United States)

    Obladen, Michael

    2014-01-01

    Artificial feeding of infants, called hand-feeding, was unsafe well into the 19th century. This paper aims to identify technical innovations which made artificial feeding less dangerous. In rapid succession from 1844 to 1886, the vulcanization of rubber, production of rubber teats, cooling machines for large-scale ice production, techniques for milk pasteurization, evaporation and condensation, and packing in closed tins were invented or initiated. Remarkably, most of these inventions preceded the discovery of pathogenic bacteria. The producers of proprietary infant formula made immediate use of these innovations, whereas in the private household artificial feeding remained highly dangerous - mostly because of ignorance about bacteria and hygiene, and partly because the equipment for safe storage, transport, preparation and application of baby food was lacking.

    2016-11-01

    Microbial filter-feeders form an important group of plankton with significance to the aquatic food webs. While the concept of filter-feeding is straightforward, our quantitative understanding of microbial filter-feeding leaves a lot to be desired. As a model organism, we focus on the filter-feeding choanoflagellate Diaphanoeca grandis. We quantify the feeding flow using particle tracking, and demonstrate that hydrodynamic theory underestimates the observed clearance rate by an order of magnitude. We find similar discrepancies for other choanoflagellate species, highlighting an apparent paradox. To resolve the paradox we argue that D. grandis and other choanoflagellates must have so far unbeknownst morphological features. Specifically, we suggest a flagellar vane that connects the flagellum to the filter, as known in choanocytes of sponges, creating a radically different, and order of magnitude more capable, pumping mechanism.

    2012-10-01

    The current study examined the associations between children's and mother's food neophobia and parental feeding practices. Eighty-five mothers of 3- to 12-year old children (M=5.7 years; 52% girls) completed a questionnaire online about food neophobia and feeding practices. Mothers with children high in food neophobia used more restriction for health and less monitoring. Mothers with food neophobic children and mothers who were themselves food neophobic also reported that they do not make healthy foods readily available for their children. Mothers high in food neophobia also used more restriction for weight. This study is a starting point for understanding the link between neophobia and feeding practices, but future longitudinal work is needed in order to determine direction of effects. However, interventions could be created to help parents understand the importance of feeding practices for promoting children's food acceptance.

    1981-02-01

    In all regions of the developing world, UNICEF cooperates in various activities and services in support of breastfeeding and appropriate weaning practices, some of long standing. In May 1981, on the basis of its own field research and of national and international studies, the UNICEF Secretariat in New York submitted a report on infant and young child feeding to its Executive Board. Excerpts concerning the main areas of UNICEF cooperation in programs to support breastfeeding are given here, covering the following areas: surveillance of breastfeeding trends; orientation and training of health professionals and other health workers; orientation of teachers and extension workers; information material for mothers; health services practices; nutrition programs for women and children; professional health organizations and other nongovernmental organizations; information media; social support systems; and code of marketing of breast milk substitutes.

    Mother's own milk is widely recognized as the optimal feeding for term infants, but also provides health benefits that are of vital importance for sick and preterm infants in neonatal intensive care units (NICUs), even though the growth and neurodevelopmental needs of very premature infants are best met by appropriate fortification of human milk (HM). When mother's milk is unavailable or in short supply, donor milk (DM) represents the second best alternative and, although some nutritional elements are inactivated by the pasteurization process, it still has documented advantages compared to formula. Occasionally, the concern that the use of DM might decrease breastfeeding is being raised, but reports exist in literature showing that the use of donor HM in the NICU increases breastfeeding rates at discharge for VLBW infants. The demonstrated benefits of HM highlight the importance of educating health care professionals in breastfeeding support.

    The discovery of the growth promoting property of antibiotics led to their use as antibiotic feed additives (AFAs) in animal feed at sub-therapeutic doses. Although this has been beneficial for animal health and productivity, it has been, essentially, a double-edged sword. The continued and non-judicious use of AFAs has led to the selection and dissemination of antibiotic-resistant strains of poultry pathogens such as Salmonella, Campylobacter and Escherichia coli. The rapid spread of drug-resistant pathogens as well as emergence of antibiotic-related environmental pollutants is of global concern. Hence, the identification and development of new and effective alternatives to antibiotics that do not hinder productivity is imperative. For this, it is essential to understand not only the molecular basis of development of resistance to AFAs but also the mechanisms of action of AFA alternatives and how they differ from AFAs. This review provides a molecular perspective on the alternatives to antibiotics that have been proposed till date and their current trends, as well as novel approaches such as development of improved delivery systems.

    Full Text Available A total of 3230 samples of feed ingredients of vegetable and animal origin and commercially available compound poultry feed received over a period of 5 years at Feed Testing Laboratory of the Institute were tested for Aflatoxin B1 contents (ppb . In all feed ingredients and compound feed stuffs, minimum level of aflatoxin B1 was 13 ppb and maximum level was found to be 78 ppb. No correlation of aflatoxin levels with month of collection of the year which are subject to variation in temperature and humidity could be detected. Mean values of aflatoxin concentration in feed stuffs such as rice, rice polish, wheat bran, wheat bread, maize, fish meal, blood meal, bone meal, guar meal, corn gluten 30%, corn gluten 60%, sun flower meal, soyabean meal and cotton seed meal were found to be higher than safe level of 20 ppb recommended by FDA.

  10. Gynecologic concerns in patients with cloacal anomaly.

    Science.gov (United States)

    Breech, Lesley

    2016-04-01

    Children with anorectal malformations (ARM) constitute a significant group within a pediatric surgery practice. It is important with female cases of anorectal malformations to consider the association of gynecologic anomalies, especially at the time of the definitive repair. However, it is critical to consider the association of such gynecologic anomalies when caring for patients with a cloacal anomaly. If not recognized, an opportunity to diagnose and treat such anomalies may be missed with the possibility of negative implications for future reproductive capacity. With the knowledge of the associated anomalies and long-term sequelae, surgeons can provide better care for girls and important counseling for parents. Knowledge of reproductive related issues in females with cloaca allows the pediatric surgeon an opportunity both, to provide optimal surgical management in infancy, childhood, and into young adulthood and to collaborate medically and surgically with an experienced gynecologist in patients with more complex anatomic variations. Appropriate counseling for patients and families about potential reproductive concerns that may develop many years after the definitive surgical repair allows preparation and planning to preserve future fertility.

  11. Critics voice concerns about counseling by telephone.

    Science.gov (United States)

    1996-05-31

    A key issue in the debate over the Confide HIV-antibody home test kit is whether face-to-face counseling about HIV is necessary. The Confide kit, developed by Direct Access Diagnostics, includes written materials for pre-test counseling written by former U.S. Surgeon General C. Everett Koop. Telephone counselors have been trained in consultation with the American Social Health Association and Cicatelli Associations, which trains for the New York State Health Department. Currently, 17 percent of Americans who undergo HIV-antibody testing get the results by telephone, according to 1992 data from the National Health Interview Survey. The AIDS Foundation Houston feels telephone counseling is not sufficient. Additionally, the National Association of People with AIDS (NAPWA) is concerned that callers who hear the recorded message announcing they tested negative will hang up the telephone without listening to additional information about how to take precautions to remain uninfected. Anna Forbes, an AIDS policy consultant, points out that Confide's counseling method also makes it harder to emphasize the fact that a negative test result does not necessarily mean the person is uninfected. Currently, Direct Access Diagnostics is the only company offering HIV-antibody home test kits. At least two other companies are awaiting approval from the Food and Drug Administration (FDA) to begin marketing of a home test kit over the counter: ChemTrak, based in Sunnyvale, CA, and Home Access, based in Chicago.

  12. Resolving issues concerning Eskdalemuir geomagnetic hourly values

    S. Macmillan

    2011-02-01

    Full Text Available The hourly values of the geomagnetic field from 1911 to 1931 derived from measurements made at Eskdalemuir observatory in the UK, and available online from the World Data Centre for Geomagnetism at http://www.wdc.bgs.ac.uk/, have now been corrected. Previously they were 2-point averaged and transformed from the original north, east and vertical down values in the tables in the observatory yearbooks. This paper documents the course of events from discovering the post-processing done to the data to the final resolution of the problem. As it was through the development of a new index, the Inter-Hour Variability index, that this post-processing came to light, we provide a revised series of this index for Eskdalemuir and compare it with that from another European observatory. Conclusions of studies concerning long-term magnetic field variability and inferred solar variability, whilst not necessarily consistent with one another, are not obviously invalidated by the incorrect hourly values from Eskdalemuir. This series of events illustrates the challenges that lie ahead in removing any remaining errors and inconsistencies in the data holdings of different World Data Centres.

    The Zika virus outbreaks highlight the growing importance need for a reliable, specific and rapid diagnostic device to detect Zika virus, as it is often recognized as a mild disease without being identified. Many Zika virus infection cases have been misdiagnosed or underreported because of the non-specific clinical presentation. The aim of this review was to provide a critical and comprehensive overview of the published peer-reviewed evidence related to clinical presentations, various diagnostic methods and modes of transmission of Zika virus infection, as well as potential therapeutic targets to combat microcephaly. Zika virus is mainly transmitted through bites from Aedes aegypti mosquito. It can also be transmitted through blood, perinatally and sexually. Pregnant women are advised to postpone or avoid travelling to areas where active Zika virus transmission is reported, as this infection is directly linked to foetal microcephaly. Due to the high prevalence of Guillain-Barre syndrome and microcephaly in the endemic area, it is vital to confirm the diagnosis of Zika virus. Zika virus infection had been declared as a public health emergency and of international concern by the World Health Organisation. Governments and agencies should play an important role in terms of investing time and resources to fundamentally understand this infection so that a vaccine can be developed besides raising awareness.

  14. Female feticide in India: Issues and concerns

    Directory of Open Access Journals (Sweden)

    Garg S

    2008-01-01

    Full Text Available The preference for a son continues to be a prevalent norm in the traditional Indian household. This is evident from the declining sex ratio which has dropped to alarming levels, especially in the northern states according to Census 2001 reports. The proliferation and abuse of advanced technologies coupled with social factors contributing to the low status of women such as dowry, concerns with family name and looking up to the son as a breadwinner has made the evil practice of female feticide to become common in the middle and higher socioeconomic households, especially in the northern states. Despite the existence of the Prenatal Diagnostic Techniques Act, there is a dire need to strengthen this law since the number of convictions is despairingly low as compared to the burden posed by this crime. Moreover, it is necessary to gear efforts against the cultural, economic and religious roots of this social malady by woman empowerment and intensive Information, Education and Communication campaigns. The medical colleges and professional bodies have a vital role to play by sensitizing medical students who are the doctors of tomorrow.

  15. Benchmarketing - Fashionable Term Concerning Traditional Processes

    2016-06-01

    Full Text Available Marketing is a major factor to boost the competitiveness of the firm in an environment which is more and more turbulent. It centers the company’s management as being the ideal satisfaction of the current and potential consumer. This is why, in our conception, the marketing’s management represents a subsystem of the company’s’ general management by which shall be administered to specific activities, and also designed to contour the company’s’ activity object. In this article, the intent is to highlight the fact that the benchmarketing has come loose from cultivating the traditional process to the innovative organizational culture product. In this paper, the authors consider benchmarketing as a process of qualitative organizational culture adaptation to market requirements, depending on the context, so as to ensure the improvement of the economic criteria of appreciation of the business lucrative activities. Based on direct observations concerning small firms, followed by analysis, comparison and synthesis, the authors suggest taking into consideration the theoretical and practical benchmarketings’ approach, as being the current strategy of acquiring and cultivating excellence, as initiation philosophy and business development.

    2016-06-01

    An alarming rise in rates of paediatric population committing self-immolation acts is a growing social and medical problem. In recent times there seems to be a rising concern in paediatric population. A study was conducted at a government tertiary care burn centre over 5 years in paediatric age group of middle and upper lower class families. Most had deep partial thickness burns. Psychiatric and personality disorder were found in 24.03% and 31.46% patients respectively. Kerosene was the main agent chosen to inflict injury. The average length of hospital stay was 19.8 days. The crude mortality rate observed was 38.2%. With cultural and socio-economic changes children and adolescents are exposed to increased levels of stress and peer pressure leaving them vulnerable. A multidisciplinary care involving medical, psychological and social support is required. Identifying children at risk and proper counselling and support can form an important strategy at prevention rather than cure. Copyright © 2016 Elsevier Ltd and ISBI. All rights reserved.

  18. Wireless Network Security Vulnerabilities and Concerns

    Mushtaq, Ahmad

    The dilemma of cyber communications insecurity has existed all the times since the beginning of the network communications. The problems and concerns of unauthorized access and hacking has existed form the time of introduction of world wide web communication and Internet's expansion for popular use in 1990s, and has remained till present time as one of the most important issues. The wireless network security is no exception. Serious and continuous efforts of investigation, research and development has been going on for the last several decades to achieve the goal of provision of 100 percent or full proof security for all the protocols of networking architectures including the wireless networking. Some very reliable and robust strategies have been developed and deployed which has made network communications more and more secure. However, the most desired goal of complete security has yet to see the light of the day. The latest Cyber War scenario, reported in the media of intrusion and hacking of each other's defense and secret agencies between the two super powers USA and China has further aggravated the situation. This sort of intrusion by hackers between other countries such as India and Pakistan, Israel and Middle East countries has also been going on and reported in the media frequently.

    The Proximity Effect is a critical problem in EB Lithography which is used in Photomask writing. Proximity Effect means that an electron shot by gun scatters by collided with resist molecule or substrate atom causes CD variation depending on pattern density [1]. Scattering by collision with resist molecule is called as "forward scattering", that affects in dozens of nanometer range, and with substrate atom is called as "backward scattering, that affects approximately 10 micrometer in 50keV acceleration voltage respectively. In conventional Proximity Effect Correction (PEC) for mask writing, we don't need to think forward scattering effect. However we should think about forward scattering because of smaller feature size. We have proposed a PEC software product named "PATACON PC-Cluster"[2], which can concern forward scattering and calculate optimum dose modulation. In this communication, we explain the PEC processing throughput when the that takes forward scattering into account. The key technique is to use different processing field size for forward scattering calculation. Additionally, the possibility is shown that effective PEC may be available by connecting forward scattering and backward scattering.

    Lactoferrin is a multifunctional, iron-binding glycoprotein found in milk and other exocrine secretions. Lactoferrin in milk plays vital roles in the healthy development of newborn mammals, and is also an innate resistance factor involved in the prevention of mammary gland infection by microorganisms. Inflammation of the udder because of bacterial infection is referred to as mastitis. There have been many investigations into the relationships between lactoferrin and mastitis, which fall into several categories. The main categories are fluctuations in the lactoferrin concentration of milk, lactoferrin activity against mastitis pathogens, elucidation of the processes underlying the onset of mastitis, participation of lactoferrin in the immune system, and utilization of lactoferrin in mastitis treatment and prevention. This minireview describes lactoferrin research concerning bovine mastitis. In the 1970s, many researchers reported that the lactoferrin concentration fluctuates in milk from cows with mastitis. From the late 1980s, many studies clarified the infection-defense mechanism in the udder and the contribution of lactoferrin to the immune system. After the year 2000, the processes underlying the onset of mastitis were elucidated in vivo and in vitro, and lactoferrin was applied for the treatment and prevention of mastitis.

  1. Hydrogeological Issues Concerning the Thar Lignite Prospect

    Full Text Available The paper is concerned with the hydrogeological appraisal of the proposed mining operations in theThar lignite field in Sindh, Pakistan. The Thar coalfield covers an area of approximately 9000km2 andcontains three lignite seams lying at depth of 130m to 250 m. In the Thar lignite field, the presence ofthree main aquifers induces pore pressure in the rock mass surrounding the lignite seams and makes highwall slopes potentially unsafe. It is, therefore, necessary to dewater the rock mass before commencingmining excavations. The paper describes the proposed mine dewatering scheme to facilitatedepressurising of the rock mass surrounding the mining excavations. Inflow prediction of groundwater tothe surface mining excavation was carried out using a SEEP/W finite element software package. Thesimulation results show that the ground water inflow from the Top aquifer is 114m3/d, from theIntermediate confined aquifer is 141m3/d and from the Bottom confined aquifer is 1.28 x 105 m3 /d. Theseresults were compared with the analytical solutions which indicated that the relative error of estimation ofinflow quantities varies from 3.4 % to 6.4%.

    The results of a study of proposed lunar base architectures to identify issues concerning centralized and decentralized power system deployment options are presented. The power system consists of the energy producing system (power plant), the power conditioning components used to convert the generated power into the form desired for transmission, the transmission lines that conduct this power from the power sources to the loads, and the primary power conditioning hardware located at the user end. Three power system architectures, centralized, hybrid, and decentralized, were evaluated during the course of this study. Candidate power sources were characterized with respect to mass and radiator area. Two electrical models were created for each architecture to identify the preferred method of power transmission, dc or ac. Each model allowed the transmission voltage level to be varied at assess the impact on power system mass. The ac power system models also permitted the transmission line configurations and placements to determine the best conductor construction and installation location. Key parameters used to evaluate each configuration were power source and power conditioning component efficiencies, masses, and radiator areas; transmission line masses and operating temperatures; and total system mass.

    Breast milk alone, given at standard recommended volumes (150 to 180 mL/kg/d), is not adequate to meet the protein, energy, and other nutrient requirements of growing preterm or low birth weight infants. One strategy that may be used to address these potential nutrient deficits is to give infants enteral feeds in excess of 200 mL/kg/d ('high-volume' feeds). This approach may increase nutrient uptake and growth rates, but concerns include that high-volume enteral feeds may cause feed intolerance, gastro-oesophageal reflux, aspiration pneumonia, necrotising enterocolitis, or complications related to fluid overload, including patent ductus arteriosus and bronchopulmonary dysplasia. To assess the effect on growth and safety of feeding preterm or low birth weight infants with high (> 200 mL/kg/d) versus standard (≤ 200 mL/kg/d) volume of enteral feeds. Infants in intervention and control groups should have received the same type of milk (breast milk, formula, or both), the same fortification or micronutrient supplements, and the same enteral feeding regimen (bolus, continuous) and rate of feed volume advancement.To conduct subgroup analyses based on type of milk (breast milk vs formula), gestational age or birth weight category of included infants (very preterm or VLBW vs preterm or LBW), presence of intrauterine growth restriction (using birth weight relative to the reference population as a surrogate), and income level of the country in which the trial was conducted (low or middle income vs high income) (see 'Subgroup analysis and investigation of heterogeneity'). We used the Cochrane Neonatal standard search strategy, which included searches of the Cochrane Central Register of Controlled Trials (CENTRAL; 2017, Issue 2) in the Cochrane Library; MEDLINE (1946 to November 2016); Embase (1974 to November 2016); and the Cumulative Index to Nursing and Allied Health Literature (CINAHL; 1982 to November 2016), as well as conference proceedings, previous reviews, and trial

    Full Text Available Orofacial clefts (OFC are one of the most common congenital problems seen with a very high incidence. It imparts a negative effect on the overall health of the child by hindering in his feeding practices, normal facial growth, development of dentition and hence speech. Infants born with orofacial clefts have oronasal communication which creates a problem with the creation of negative pressure inside the oral cavity required for suckling.The treatment for such patients is with the multidisciplinary approach but the preliminary  concern for the neonate is to help with the feeding for which a feeding appliance is given. This case report presents a case of a 3-day old infant to whom a feeding appliance was given to aid in suckling.

    This work presents current information on the presence of aflatoxins (AFs) and zearalenone (ZEN) in feed and feed ingredients from Punjab, Pakistan. The 105 samples tested were concentrated feed, i.e., cotton seed meal (18 samples) and soybean meal (14), and feed ingredients, i.e., crushed corn (17), crushed wheat (15), barley (17). and poultry feed (24). Samples were analyzed using high-performance liquid chromatography equipped with a fluorescence detector. Analysis revealed that 69 of 105 samples were contaminated with AFs, and the highest mean concentrations of AFB1 (6.20 μg/kg) and total AFs (9.30 μg/kg) were found in poultry feed samples. The mean total AF concentrations ranged from the limit of quantification to 165.5 μg/kg. However, 75 of the 105 samples were positive for ZEN. The highest mean concentration (19.45 μg/kg) was found in poultry feed samples. The mean ZEN concentrations were 0.15 to 145.30 μg/kg. The prevalence of AFs and ZEN was high in feed and feed ingredients and needs urgent attention.

    We consider feed-forward and auto-regulation feed-forward neural (weighted) coupled cell networks. In feed-forward neural networks, cells are arranged in layers such that the cells of the first layer have empty input set and cells of each other layer receive only inputs from cells of the previous layer. An auto-regulation feed-forward neural coupled cell network is a feed-forward neural network where additionally some cells of the first layer have auto-regulation, that is, they have a self-loop. Given a network structure, a robust pattern of synchrony is a space defined in terms of equalities of cell coordinates that is flow-invariant for any coupled cell system (with additive input structure) associated with the network. In this paper, we describe the robust patterns of synchrony for feed-forward and auto-regulation feed-forward neural networks. Regarding feed-forward neural networks, we show that only cells in the same layer can synchronize. On the other hand, in the presence of auto-regulation, we prove that cells in different layers can synchronize in a robust way and we give a characterization of the possible patterns of synchrony that can occur for auto-regulation feed-forward neural networks.

    2016-09-01

    Full Text Available Inadequate feeding is the major factor for low livestock productivity in India. In dairying, feed cost is a major input and feeding practices has to be improved to ensure profits. Still the small scale farmers are following traditional feeding practices and fail to address the complexities involved in ration formulation. To address the complexities in ration balancing based on the nutrient requirements for different categories of livestock, nutrient composition of wide range of feed resources and the cost - a number of expert systems have been developed. However existing expert systems have not been widely used by majority of small farmers due to lack of awareness, access and basic skills required to operate. To address these limitations, “Feed Assist” a farmer friendly expert system for balanced feeding of dairy animals at least cost has been developed using linear programming. “Feed Assist” does not require much expertise to operate and enables the farmers to formulate least cost rations for different categories of livestock using locally available feed resources.

  15. Pretreatment and Process to Control Mycotoxin in Sustainable Feed Production Using Extracts of Neem (Azadirachta indica

    Ida Idayu Muhamad

    2014-01-01

    Full Text Available By some recent estimates, mycotoxins affect as much as 25% of the world’s food crops each year. These highly toxic, naturally occurring compounds are by products (metabolites of the growth of fungi or moulds. Mycotoxins can result in significant economic loss for crop producers and broiler producers since it represent an ongoing risk to profitability. Factors that contribute to mycotoxin contamination of food and feed include environmental, socio-economic and food production. Environmental conditions especially high humidity and temperatures favour fungal proliferation resulting in contamination of food and feed. The resulting implications include immuno-suppression, impaired growth, various cancers and death depending on the type, period and amount of exposure. Mycotoxin concerns have grown during the last few decades because of their implications to human and animal health, productivity, economics of their management and trade. This has led to development of maximum tolerated limits for mycotoxins in various countries. This paper highlights the use of naturally derived aflatoxin inhibitors from Azadirachtin compound of neem oil, and tray drying in controlling moisture content to inhibit the aflatoxin contamination in pretreated soy based animal feed. High moisture content found in soy based animal feed increases the risk of fungal growth during storage. Neem extract has shown potential as an effective feed additive to minimize the growth of fungi and possibly reduce the risk of toxic effects from mycotoxin production. Preservation methods by means of tray drying have also shown positive results towards the control of fungal growth.

  16. Trace analysis of sulfamethazine in animal feed, human urine, and wastewater by electron capture gas chromatography

    1981-12-01

    Sulfamethazine, a widely used antibacterial drug additive in feeds for swine, chickens, and cattle, was scheduled for toxicological evaluation because of potential human health hazards associated with its residues in edible animal tissues. Analytical chemical procedures that would ensure proper concentration, homogeneity, and stability of the drug in dosed feed and its safe usage during the animal studies were prerequisites for such toxicological tests. Electron capture gas chromatographic (EC/GC) methods were therefore devised for the analysis of sulfamethazine residues in animal feed, human urine, and wastewater at levels as low as 100, 10, and 10 ppb, respectively. Sample extracts were cleaned up by using liquid/liquid partitioning, and the extracts were subjected to two derivatizations followed by cleanup on a silica gel column. The derivatizations of sulfamethazine consisted of methylation followed by trifluoroacetylation of the primary amine function. Ancillary data concerning stability of the compound in animal feed, water, and as a dry residue on glass, extraction efficiencies, partition values with various solvents, and the analysis of residues in feed by high pressure liquid chromatography (HPLC) at levels as low as 1.0 ppm are presented.

    Growth in extraction of bitumen from oil sands has raised concerns about influences of this industry on surrounding environments. Water clearance rate (a surrogate of feeding rate by Daphnia magna) in water containing D. magna exposed to oil sands process-affected water (OSPW) and its principal components, dissolved component (DC) and suspended particulate matter (SPM), was reduced to 72, 29, and 59% of controls, respectively. This study also examined several possible mechanisms for the observed changes algal cell density (i.e., feeding rate). There was no change in the digestive enzymes trypsin or amylase when D. magna were exposed to DC or SPM; however, exposure to total OSPW reduced trypsin activity. Mandible rolling or post-abdominal rejections, which are indicators of feeding and palatability of food, were not affected by any exposures to OSPW. Beating of thoracic limbs, which provides water flow toward the feeding groove, was reduced by exposure to SPM or total OSPW. Peristaltic activity was reduced by exposure to DC, which then might result in reduced digestion time in D. magna exposed to DC, SPM or whole OSPW. All treatments caused an increase in numbers of intact algae cells in the hindgut and excreted material. These results suggest that both DC and SPM affect feeding of D. magna by impairing actions of the digestive system, but most probably not by reducing rates of ingestion.

    To explore factors at the family caregiver and nursing home administrative levels that may affect participation in a clinical trial to determine the efficacy of hand feeding vs. percutaneous gastrostomy tube feeding in persons with late-stage dementia. Decision-making regarding use of tube feeding vs. hand feeding for persons with late-stage dementia is fraught with practical, emotional and ethical issues and is not informed by high levels of evidence. Qualitative case study. Transcripts of focus groups with family caregivers were reviewed for themes guided by behavioural theory. Analyses of notes from contacts with nursing home administrators and staff were reviewed for themes guided by an organizational readiness model. Data were collected between the years 2009-2012. Factors related to caregiver willingness to participate included understanding of the prognosis of dementia, perceptions of feeding needs and clarity about research protocols. Nursing home willingness to participate was influenced by corporate approval, concerns about legal and regulatory issues, and prior relationships with investigators. Participation in rigorous trials requires lengthy navigation of complex corporate requirements and training competent study staff. Objective deliberation by caregivers will depend on appropriate recruitment timing, design of recruitment materials and understanding of study requirements. The clinical standards and policy environment and the secular trends there-in have relevance to the responses of people at all levels. © 2014 John Wiley & Sons Ltd.

  19. Agricultural sources of contaminants of emerging concern and adverse health effects on freshwater fish

    2011-01-01

    Agricultural contaminants of emerging concern (CECs) are generally thought of as certain classes of chemicals associated with animal feeding and production facilities. Veterinary pharmaceuticals used in animal food production systems represent one of the largest groups of CECs. In our review, we discuss the extensive increase in use of antibiotics in animal feeding operations (AFOs) around the world. AFOs are a major consumer of antibiotics and other veterinary pharmaceuticals and over the past decade there has been growing information on the occurrence, release, and fate of CECs from animal food production operations, including the application of pharmaceutical-containing manure to agricultural fields and releases from waste lagoons. Concentrations of CECs in surface and ground water in proximity to AFOs correspond to their presence in the AFO wastes. In many cases, the environmental concentrations of agriculturally-derived CECs are below toxicity thresholds. Hormones and hormone replacement compounds are a notable exception, where chemical concentrations near AFOs can exceed concentrations known to cause adverse effects on endocrine-related functions in fish. In addition, some agricultural pesticides, once thought to be safe to non-target organisms, have demonstrated endocrine-related effects that may pose threats to fish populations in agricultural regions. That is, we have pesticides with emerging concerns, thus, the concern is emerging and not necessarily the chemical. In this light, one must consider certain agricultural pesticides to be included in the list of CECs. Even though agricultural pesticides are routinely evaluated in regulatory testing schemes which have been used for decades, the potential hazards of some pesticides have only recently been emerging. Emerging concerns of pesticides in fish include interference with hormone signaling pathways; additive (or more than additive) effects from pesticide mixtures; and adverse population-level effects at

  20. Cholera:a great global concern

    2011-01-01

    Cholera, caused by the infection of toxigenicVibrio cholerae (V. cholerae)to humans, is a life threatening diarrheal disease with epidemic and pandemic potential. TheV. cholerae, both O1 and O139 serogroups, produce a potent enterotoxin (cholera toxin) responsible for the lethal symptoms of the disease. TheO1 serogroup has two biotypes (phenotypes), classical and El Tor; each of which has two major serotypes (based on antigenic responses), Ogawa and Inaba and the extremely rare Hikojima.V. choleraeO1 strains interconvert and switch between the Ogawa and Inaba serotypes. Fluid and electrolyte replacement is the mainstay of treatment of cholera patients; the severe cases require antibiotic treatment to reduce the duration of illness and replacement of fluid intake. The antibiotic therapy currently has faced difficulties due to the rapid emergence and spread of multidrug resistantV. cholerae causing several outbreaks in the globe. Currently, cholera has been becoming endemic in an increasing number of geographical areas, reflecting a failure in implementation of control measures. However, the current safe oral vaccines lower the number of resistant infections and could thus represent an effective intervention measure to control antibiotic resistance in cholera. Overall, the priorities for cholera control remain public health interventions through improved drinking water, sanitation, surveillance and access to health care facilities, and further development of safe, effective and appropriate vaccines. Thus, this review describes the facts and phenomena related to the disease cholera, which is still a great threat mainly to the developing countries, and hence a grave global concern too.
