    Enacted in 1950, Public Law 480 (PL480) dramatically increased the volume of U.S.food aid and the scope of interventions it supports. Billions of dollars have been invested, both to enhance the diets of chronically undernourished people in development settings, and to support nutritional needs during conflicts and natural disasters. Review the institutional processes-from procurement to delivery-that support this programming. We examined the systems that govern and oversee the many components of food aid programming and the extent to which they support a whole-of-government, multi-agency food aid agenda. We conducted consultations with US government employees and contractors, academics, industry representatives, donor agency staff United Nations personnel, and field-level food aid programming technical staff from many countries. A survey of USAID implementing partners conducted among 64 responding offices in 40 countries provided data on the use and effectiveness of enriched, fortified, or blended Title II commodities, the use of new commodities, and related procurement or logistics aspects. Expert panels provided input and feedback throughout the process. We identified potential improvements to overall delivery and cost-effectiveness of USAID programming to better meet the nutrition needs of beneficiaries. Options include changes in product formulation, the range of products provided, and/or the modes of product approval, processing, procurement, and distribution. This research points to several improvements in processes related to food aid: 1) Establish an interagency committee to oversee all government interests in the food aid agenda through an ongoing review process. 2) Enhance processes and quality assurance along the product value chain including the importance of effective interaction with the private sector to incorporate industry best practices and create public-private partnerships to promote product innovations. 3) Strengthen the evidence base for

    Gastrointestinal physiology is dynamic and complex at the best of times, and a multitude of known variables can affect the overall bioavailability of drugs delivered via the oral route. Yet while the influences of food and beverage intake as just two of these variables on oral drug delivery have been extensively documented in the wider literature, specific information on their effects remains sporadic, and is not so much contextually reviewed. Food co-ingestion with oral dosage forms can mediate several changes to drug bioavailability, yet the precise mechanisms underlying this have yet to be fully elucidated. Likewise, the often detrimental effects of alcohol (ethanol) on dosage form performance have been widely observed experimentally, but knowledge of which has only moderately impacted on clinical practice. Here, we attempt to piece together the available subject matter relating to the influences of both solid and liquid foodstuffs on the gastrointestinal milieu and the implications for oral drug delivery, with particular emphasis on the behaviour of modified-release dosage forms, formulation robustness and drug absorption. Providing better insight into these influences, and exemplifying cases where formulations have been developed or modified to circumvent their associated problems, can help to appropriately direct the design of future in vitro digestive modelling systems as well as oral dosage forms resilient to these effects. Moreover, this will help to better our understanding of the impact of food and alcohol intake on normal gut behaviour and function. Copyright © 2013 Elsevier B.V. All rights reserved.

    Full Text Available Food aid is a critical component of the global food system, particularly when emergency situations arise. For the first time, we evaluate the water footprint of food aid. To do this, we draw on food aid data from theWorld Food Programme and virtual water content estimates from WaterStat. We find that the total water footprint of food aid was 10 km3 in 2005, which represents approximately 0.5% of the water footprint of food trade and 2.0% of the water footprint of land grabbing (i.e., water appropriation associated with large agricultural land deals. The United States is by far the largest food aid donor and contributes 82% of the water footprint of food aid. The countries that receive the most water embodied in aid are Ethiopia, Sudan, North Korea, Bangladesh and Afghanistan. Notably, we find that there is significant overlap between countries that receive food aid and those that have their land grabbed. Multivariate regression results indicate that donor water footprints are driven by political and environmental variables, whereas recipient water footprints are driven by land grabbing and food indicators.

    Full Text Available Permanently unsolved world food insecurity problem makes the international community search for solutions. One of the used methods is international food aid directed to developing countries. Long term analyses of the food aid flows allow to identify some tendencies that show: increase of emergency food aid and decrease of direct transfer. These tendencies also apply to the two biggest food donors i.e. the USA and the EU. The noticeable directions of changes are based on the international community initiatives, on which the national regulation are formed later.

    As part of US Agency for International Development (USAID) efforts to improve the quality of food aid products and programs, a two year study was commissioned to produce recommendations on ways to improve the quality of food aid products, programming, and institutional processes. The review determined that while much valuable work is done in both emergencies and non-emergency contexts, there is scope for improvement. Smarter programming, more careful targeting, greater attention to cost-effectiveness (in relation to planned human outcomes, not just numbers of people "fed"), enhanced coordination of interagency processes, enhanced policy harmonization among international players, and application of best practices in product formulation can help increase the impact of U.S. food aid resources.

  2. Computer-Aided Design of Nanocapsules for Therapeutic Delivery

    Directory of Open Access Journals (Sweden)

    Zeina Shreif

    2009-01-01

    Full Text Available The design of nanocapsules for targeted delivery of therapeutics presents many, often seemingly self-contradictory, constraints. An algorithm for predicting the physico-chemical characteristics of nanocapsule delivery and payload release using a novel all-atom, multiscale technique is presented. This computational method preserves key atomic-scale behaviours needed to make predictions of interactions of functionalized nanocapsules with the cell surface receptors, drug, siRNA, gene or other payload. We show how to introduce a variety of order parameters with distinct character to enable a multiscale analysis of a complex system. The all-atom formulation allows for the use of an interatomic force field, making the approach universal and avoiding recalibration with each new application. Alternatively, key parameters, which minimize the need for calibration, are also identified. Simultaneously, the methodology enables predictions of the supra-nanometer-scale behaviour, such as structural transitions and disassembly of the nanocapsule accompanying timed payload release or due to premature degradation. The final result is a Fokker–Planck equation governing the rate of stochastic payload release and structural changes and migration accompanying it. A novel “salt shaker” effect that underlies fluctuation-enhancement of payload delivery is presented. Prospects for computer-aided design of nanocapsule delivery system are discussed.

    Aditya, N P; Espinosa, Yadira Gonzalez; Norton, Ian T

    2017-07-01

    Increased health risk associated with the sedentary life style is forcing the food manufacturers to look for food products with specific or general health benefits e.g. beverages enriched with nutraceuticals like catechin, curcumin rutin. Compounds like polyphenols, flavonoids, vitamins are the good choice of bioactive compounds that can be used to fortify the food products to enhance their functionality. However due to low stability and bioavailability of these bioactives (both hydrophobic and hydrophilic) within the heterogeneous food microstructure and in the Gastro Intestinal Tract (GIT), it becomes extremely difficult to pass on the real health benefits to the consumers. Recent developments in the application of nano-delivery systems for food product development is proving to be a game changer which has raised the expectations of the researchers, food manufacturers and consumers regarding possibility of enhancing the functionality of bioactives within the fortified food products. In this direction, nano/micro delivery systems using lipids, surfactants and other materials (carbohydrates, polymers, complexes, protein) have been fabricated to stabilize and enhance the biological activity of the bioactive compounds. In the present review, current status of the various delivery systems that are used for the delivery of hydrophilic bioactives and future prospects for using other delivery systems that have been not completely explored for the delivery of hydrophilic bioactives e.g. niosomes; bilosomes, cubosomes are discussed.

    2003-08-01

    The prevalence of food allergies is increasing. Concurrently, the average maternal age at birth is also increasing. We conducted a preliminary study to evaluate whether maternal age at the time of delivery is associated with a food allergy in children. Case and control patients were identified among consecutive patients seen by one of us (AD) in the Allergy/Immunology program at the Children's Hospital Boston between 11/1/98 and 2/28/00. Case patients were born in Massachusetts and had evidence of clinical sensitivity and IgE to one or more food allergens (n = 58). Control patients were those born in Massachusetts who had a negative skin test and/or RAST to inhalant and/or food allergens (n = 96). A second comparison group consisted of all live births in Massachusetts in 1999 (n = 80,866). Information on maternal age at birth was missing from 3/58 (5%) of patients with a food allergy and 4/96 (4%) of the control patients, so these patients were not included in the analysis. The proportion of children whose mother was aged 30 and over at their birth was significantly higher in children with a food allergy than control patients (78% vs. 55% p = 0.005) and higher than all births in Massachusetts (78% vs. 53% p = 0.0002). Mothers of children with a food allergy had about three times greater odds of being aged 30 or over at the time of delivery than mothers in either of the comparison groups. Further exploration of the data using logistic regression showed that maternal age over 30 at delivery and being first born were independent predictors of the child having a food allergy. In this study, the presence of a food allergy in children was related to older maternal age at delivery. Additional studies are needed to further evaluate this relationship and its potential implication in preventive strategies for food allergies in children.

    Preterm delivery represents a substantial problem in perinatal medicine worldwide. Current knowledge on potential influences of probiotics in food on pregnancy complications caused by microbes is limited. We hypothesized that intake of food with probiotics might reduce pregnancy complications caused by pathogenic microorganisms and, through this, reduce the risk of spontaneous preterm delivery. This study was performed in the Norwegian Mother and Child Cohort on the basis of answers to a food-frequency questionnaire. We studied intake of milk-based products containing probiotic lactobacilli and spontaneous preterm delivery by using a prospective cohort study design (n = 950 cases and 17,938 controls) for the pregnancy outcome of spontaneous preterm delivery (delivery were associated with any intake of milk-based probiotic products in an adjusted model [odds ratio (OR): 0.857; 95% CI: 0.741, 0.992]. By categorizing intake into none, low, and high intakes of the milk-based probiotic products, a significant association was observed for high intake (OR: 0.820; 95% CI: 0.681, 0.986). Women who reported habitual intake of probiotic dairy products had a reduced risk of spontaneous preterm delivery.

    Mao, Like; Roos, Yrjö H; Biliaderis, Costas G; Miao, Song

    2017-10-13

    Food flavor is an important attribute of quality food, and it largely determines consumer food preference. Many food products exist as emulsions or experience emulsification during processing, and therefore, a good understanding of flavor release from emulsions is essential to design food with desirable flavor characteristics. Emulsions are biphasic systems, where flavor compounds are partitioning into different phases, and the releases can be modulated through different ways. Emulsion ingredients, such as oils, emulsifiers, thickening agents, can interact with flavor compounds, thus modifying the thermodynamic behavior of flavor compounds. Emulsion structures, including droplet size and size distribution, viscosity, interface thickness, etc., can influence flavor component partition and their diffusion in the emulsions, resulting in different release kinetics. When emulsions are consumed in the mouth, both emulsion ingredients and structures undergo significant changes, resulting in different flavor perception. Special design of emulsion structures in the water phase, oil phase, and interface provides emulsions with great potential as delivery systems to control flavor release in wider applications. This review provides an overview of the current understanding of flavor release from emulsions, and how emulsions can behave as delivery systems for flavor compounds to better design novel food products with enhanced sensorial and nutritional attributes.

    Full Text Available Abstract Background The burden of disease of hearing disorders among adults is high, but a significant part goes undetected. Screening programs in combination with the delivery of hearing aids can alleviate this situation, but the economic attractiveness of such programs is unknown. This study aims to evaluate the population-level costs, effects and cost-effectiveness of alternative delivering hearing aids models in Tamil Nadu, India Methods In an observational study design, we estimated total costs and effects of two active screening programs in the community in combination with the provision of hearing aids at secondary care level, and the costs and effects of the provision of hearing aids at tertiary care level. Screening and hearing aid delivery costs were estimated on the basis of program records and an empirical assessment of health personnel time input. Household costs for seeking and undergoing hearing health care were collected with a questionnaire (see Additional file 2. Health effects were estimated on the basis of compliance with the hearing aid, and associated changes in disability, and were expressed in disability-adjusted life years (DALYs averted. Results Active screening and provision of hearing aids at the secondary care level costs around Rs.7,000 (US$152 per patient, whereas provision of hearing aids at the tertiary care level costs Rs 5,693 (US$122 per patient. The cost per DALY averted was around RS 42,200 (US$900 at secondary care level and Rs 33,900 (US$720 at tertiary care level. The majority of people did consult other providers before being screened in the community. Costs of food and transport ranged between Rs. 2 (US$0,04 and Rs. 39 (US$0,83. Conclusion Active screening and provision of hearing aids at the secondary care level is slightly more costly than passive screening and fitting of hearing aids at the tertiary care level, but seems also able to reach a higher coverage of hearing aids services.

    Globalisation affects all facets of human life, including health and well being. The HIV/AIDS epidemic has highlighted the global nature of human health and welfare and globalisation has given rise to a trend toward finding common solutions to global health challenges. Numerous international funds have been set up in recent times to address global health challenges such as HIV. However, despite increasingly large amounts of funding for health initiatives being made available to poorer regions of the world, HIV infection rates and prevalence continue to increase world wide. As a result, the AIDS epidemic is expanding and intensifying globally. Worst affected are undoubtedly the poorer regions of the world as combinations of poverty, disease, famine, political and economic instability and weak health infrastructure exacerbate the severe and far-reaching impacts of the epidemic. One of the major reasons for the apparent ineffectiveness of global interventions is historical weaknesses in the health systems of underdeveloped countries, which contribute to bottlenecks in the distribution and utilisation of funds. Strengthening these health systems, although a vital component in addressing the global epidemic, must however be accompanied by mitigation of other determinants as well. These are intrinsically complex and include social and environmental factors, sexual behaviour, issues of human rights and biological factors, all of which contribute to HIV transmission, progression and mortality. An equally important factor is ensuring an equitable balance between prevention and treatment programmes in order to holistically address the challenges presented by the epidemic. PMID:16060961

    Full Text Available In this article, energetic and technical paradoxes in food nanotechnologies and traditional approaches to evaluation of energy recourses using are considered. Hypotheses of improvement of food production energy technologies are formulated. Classification of principles of address delivery of energy to food raw materials elements is given. We had substantiated the perspective objectives for heat-pumps installations and biphasic heat-transfer systems. The energy efficiency of new technolo-gies is compared on base of the number of energy impact. Principles of mass transfer modeling in ex-traction, dehydration and pasteurization combined processes are considered by food production exam-ple. The objectives of mathematical modeling of combined hydrodynamic and heat and mass transfer processes in modern energy technologies are set. The fuel energy conversion diagrams for drying, in-novative installations on the base of thermal siphons, heat pumps and electromagnetic energy genera-tors are represented. In this article, we illustrate how electromagnetic field, biphasic heat-transfer sys-tems and heat pumps can be effective tools for energy efficiency technologies.

    The addition of probiotic bacteria to the space food system is expected to confer immunostimulatory benefits on crewmembers during spaceflight, counteracting the immune dysregulation that has been documented in spaceflight. Specifically, the probiotic Lactobacillus acidophilus has been shown to promote health benefits including antagonism towards and inhibition of virulence related gene expression in pathogens, mucosal stimulation of immune cells, and a reduction in the occurrence and duration of cold and flu-like symptoms. The optimum delivery system for probiotics has not been determined for spaceflight, where the food system is shelf stable and the lack of refrigeration prevents the use of traditional dairy delivery methods. This work proposes to determine whether L. acidophilus is more viable, and therefore more likely to confer immune benefit, when delivered in a capsule form or when delivered in nonfat dry milk powder with a resuscitation opportunity upon rehydration, following 0, 4, and 8 months of storage at -80degC, 4degC, and 22degC, and both prior to and after challenge with simulated gastric and intestinal juices. We hypothesize that the low moisture neutral dairy matrix provided by the nonfat dry milk, and the rehydration step prior to consumption, will extend probiotic viability and stress tolerance compared to a capsule during potential storage conditions in spaceflight and in simulated digestion conditions.

    Full Text Available Relatively high prevalence of HIV and AIDS and food insecurity in Rufiji District whilst the linkage between the two problems was not known was the basis of this study. Data were collected amongst 225 households between November 2005 and October 2006 through participatory rural appraisal (PRA, household income and expenditure survey (HIES and structured interviews. Binary logistic regression was used for analysis in which case the dependent variable was food security in terms of food insecure (0 and food secure (1 based on kilocalories consumed per adult equivalent per day. The independent variables included having been affected by HIV and AIDS in terms of not affected (0 and affected (1. The results reveal that the odds for households affected by HIV and AIDS to be food secure were 0.705 times as high as the odds for households not affected by HIV and AIDS to be food secure. This means that households affected by HIV and AIDS were less likely to be food secure as opposed to those not affected by HIV and AIDS. The B statistic for having been affected by HIV and AIDS was negative (B = -0.350 meaning that being affected by HIV and AIDS had negative impact on food security. However, the Wald statistic which shows the magnitude of impact was small (0.251 and not significant (p = 0.617. This shows that HIV and AIDS had little impact on food security. Based on these findings, it is concluded that although being affected by HIV and AIDS has negative impact on food security, it does not automatically make households food insecure, especially in a short run, and that some non-HIV and AIDS factors like high dependency ratio and low ability to buy food have bigger negative impact than that of HIV and AIDS on food security. On the basis of the conclusion, it is recommended that efforts to improve food security amongst households affected by HIV and AIDS should consider both HIV and AIDS and non-HIV and AIDS factors.

    Food delivery system is one kind of geographical information systems (GIS) that can be applied through digitation process. The main case in food delivery system is the way to determine the shortest path and food delivery vehicle movement tracking. Therefore, to make sure that the digitation process of food delivery system can be applied efficiently, it is needed to add shortest path determination facility and food delivery vehicle tracking. This research uses A Star (A*) algorithm for determining shortest path and location-based system (LBS) programming for moving food delivery vehicle object tracking. According to this research, it is generated the integrated system that can be used by food delivery driver, customer, and administrator in terms of simplifying the food delivery system. Through the application of shortest path and the tracking of moving vehicle, thus the application of food delivery system in the scope of geographical information system (GIS) can be executed.

  15. Is caesarean delivery associated with sensitization to food allergens and IgE-mediated food allergy: a systematic review.

    Several studies have shown differences in the composition of the gastrointestinal flora of children who develop sensitization to food allergens compared with non-allergic children. It has been hypothesized that changes in the gut microbiota resulting from caesarean section delivery could increase a child's risk of developing food allergy; however, studies examining the relationship between mode of delivery and food allergy have produced conflicting results. The objective of this review was to determine whether there is sufficient evidence to support an association between delivery by caesarean section and the development of sensitization to food allergens and immunoglobulin E (IgE) mediated food allergy. Using predefined inclusion and exclusion criteria, MEDLINE and PubMed were searched for studies investigating the relationship between caesarean section delivery and food allergy. The information on the quality of the studies and results were extracted and analysed systematically. The search identified four relevant studies as per our protocol. Symptomatic food allergy was used as the outcome in two studies and was found to occur more frequently in children born by caesarean section in one study while the second study found no association between food allergy diagnoses and mode of delivery. The other two studies measured levels of food antigen-specific IgE, with both studies showing an increase in sensitization to food allergens among children born by caesarean section. Overall, there is evidence that the risk of developing IgE-mediated sensitization to food allergens is increased among children delivered by caesarean section, however further studies using objectively diagnosed food allergy as the outcome are needed to verify whether this equates to an increase in confirmed food allergy. Future birth cohort studies should control for the effects of mode of delivery when investigating environmental modifiers of food allergy.

    Full Text Available Ethiopia has experienced more than five major droughts in the past three decades, leading to high dependency on international food aids. Nevertheless, studies indicate that asset depletion has not been prevented; neither did food insecurity diminish. Since 2004/5, the Productive Safety Net Programme (PSNP has been implemented to improve food security in Tigray, Northern Ethiopia. Critics point out that the implementation of food aid programmes can have negative impacts as well as positive outcomes for local communities. Accordingly, this survey study aimed to analyse the distribution and allocation of food aids in the Productive Safety Net Programme (PSNP in Tigray. Results of 479 interviews revealed that targeting different households in the PSNP has been considerably linked to socio-demographic attributes among which age and size of family were decisive factors to receive food aids. Furthermore, older households with smaller family size received more direct support. Inequality between genders was another major finding of this study. When combined with the marital status, there was also a big difference in the percentage of married or unmarried women receiving food aids. These findings could provide fundamental information for policy intervention to correct food security programmes at household level and reduce hunger. Given that, socio-demographic factors can help to identify particular and usually different requirements, vulnerabilities and coping strategies of the members of the food aid programme, so that they can be much more addressed when an emergency happens.

    Full Text Available More than 340 million new cases of sexually transmitted infections occur throughout the world every year. The average annual STIs growth rate was 17%from 1998 to 2006 in Iran. As this epidemic has progressed, relevant literatures shown that, gender has a critical element in implementation and impact of these programs. Most reproductive health programs haven’t integrated gender mainstreaming to their service deliveries. In order to explore key informants perspectives towards gender sensitive STIs/HIV/AIDS prevention service delivery, this study was done. Participants including health managers, health policy makers and reproductive health providers were selected purposefully and continued by snow ball sampling. 43 semi-structured in depth interviews with 37 key informants analyzed according to content analysis. Main categories were generated after processing and organizing the codes. Key informants clearly explained the gender sensitive STIs/HIV/AIDS prevention structure in three domains: training gender sensitive providers, facilities and management. In our country, transforming gender neural to more complete gender sensitive STIs/HIV/AIDS prevention services needs structural reforms that make these interventions more effective.

    To assess the nutritional quality of food aid delivered by food banks in France and to identify practical modifications to improve it. National-level data were collected for all food aid distributed by French food banks in 2004, and its nutrient content per 2000 kcal was estimated and compared with French recommendations for adults. Starting with the actual donation and allowing new foods into the food aid donation, linear programming was used to identify the minimum changes required in the actual donation to achieve the French recommendations. French food-bank-delivered food aid does not achieve the French recommendations for dietary fibre, ascorbic acid, vitamin D, folate, magnesium, docosahexaenoic acid, alpha-linolenic acid and the percentage of energy from saturated fatty acids. Linear programming analysis showed that these recommendations are achievable if more fruits, vegetables, legumes and fish were collected and less cheese, refined cereals and foods rich in fat, sugar and/or salt. In addition, new foods not previously collected are needed, particularly nuts, wholemeal bread and rapeseed oil. These changes increased the total edible weight (42%) and economic value (55%) of the food aid donation, with one-third of its edible weight coming from fruits and vegetables, one-third from staples, one-quarter from dairy products and approximately a tenth from meat/fish/eggs. Important changes in the types and amounts of food collected will improve the nutritional quality of food-bank-delivered food aid in France. Such changes are recommended to improve the diets of deprived French populations.

  4. Utilizing food effects to overcome challenges in delivery of lipophilic bioactives: structural design of medical and functional foods.

    Science.gov (United States)

    McClements, David Julian

    2013-12-01

    The oral bioavailability of many lipophilic bioactives, such as pharmaceuticals and nutraceuticals, is relatively low due to their poor solubility, permeability and/or chemical stability within the human gastrointestinal tract (GIT). The oral bioavailability of lipophilic bioactives can be improved by designing food matrices that control their release, solubilization, transport and absorption within the GIT. This article discusses the challenges associated with delivering lipophilic bioactive components, the impact of food composition and structure on oral bioavailability and the design of functional and medical foods for improving the oral bioavailability of lipophilic bioactives. Food-based delivery systems can be used to improve the oral bioavailability of lipophilic bioactives. There are a number of potential advantages to delivering lipophilic bioactives using functional or medical foods: greater compliance than conventional delivery forms; increased bioavailability and efficacy; and reduced variability in biological effects. However, food matrices are structurally complex multicomponent materials and research is still needed to identify optimum structures and compositions for particular bioactives.

    McClements, David Julian; Li, Yan

    2010-09-15

    There is a need for edible delivery systems to encapsulate, protect and release bioactive and functional lipophilic constituents within the food and pharmaceutical industries. These delivery systems could be used for a number of purposes: controlling lipid bioavailability; targeting the delivery of bioactive components within the gastrointestinal tract; and designing food matrices that delay lipid digestion and induce satiety. Emulsion technology is particularly suited for the design and fabrication of delivery systems for lipids. In this article we provide an overview of a number of emulsion-based technologies that can be used as edible delivery systems by the food and other industries, including conventional emulsions, nanoemulsions, multilayer emulsions, solid lipid particles, and filled hydrogel particles. Each of these delivery systems can be produced from food-grade (GRAS) ingredients (e.g., lipids, proteins, polysaccharides, surfactants, and minerals) using relatively simple processing operations (e.g., mixing, homogenizing, and thermal processing). The structure, preparation, and utilization of each type of delivery system for controlling lipid digestion are discussed. This knowledge can be used to select the most appropriate emulsion-based delivery system for specific applications, such as encapsulation, controlled digestion, and targeted release.

    Directory of Open Access Journals (Sweden)

    Gianfranco Tamburelli

    2016-06-01

    Full Text Available The increase in the number of areas where humanitarian emergencies are brought about by armed conflicts, and the enduring nature of these situations, call for research aimed at clarifying the international legal framework for food-aid operations, taking into account the developments and practices in the fields of human rights, humanitarian law, environmental law, and cooperation for sustainable development. In this article, therefore, the Author analyses the general problems of food aid in conflict areas, with a focus on a concrete situation, namely the crisis in Eastern Ukraine. The dramatic situation faced by some Ukrainian regions - where, since the spring of 2014, the World Food Programme (WFP, various other international organizations, the EU and some National Development Cooperations have been operating - underlines, in fact, the importance of reaching a clear understanding of all the different regulatory levels in the field of food aid security and safety.

    Full Text Available Information on livestock movement, animal food products processing facilities, meat inspection methods, official meat inspection records and distribution and marketing systems for processed products in Imo state, Nigeria needed for policy development interventions in the sector are not fully understood. The primary data generated with the aid of personal interviews, field observations and secondary data obtained from records accumulated by the department of veterinary services Imo state from 2001 to 2004 were used to investigate the environmental and public health issues of animal food products delivery system in state. Majority of trade animals supplied to the state originated from the northern states of the country and were brought in with trucks by road. Only two veterinary control posts served the whole state thus resulting in non-inspection and taxing of a large proportion of trade animals. Official record of trade animals supplied to the state from 2001 to 2004 ranged from 45000 – 144000 for cattle, 23000 – 96000 for goats and 11000 – 72000 for sheep per annum, with supplies increasing steadily across the years. Official slaughter points in the state were principally low-grade quality slaughter premises consisting of a thin concrete slab. Meat handling was very unhygienic with carcasses dressed beside refuse heaps of over 2 years standing. Carcasses were dragged on the ground and transported in taxi boots and open trucks. Meat inspection at these points was not thorough because of stiff resistance of butchers to carcass condemnation. Official meat inspection records for the state from 2001 to 2004 revealed that overall totals of 159,000 cattle, 101,000 goats and 67,000 sheep were slaughtered. This accounted for about 56, 57 and 57% shortfall of cattle, goat and sheep respectively supplied to the state and represents the volume of un-inspected animals during the study period. Fascioliasis and tuberculosis were the most common

    Jessica E Yager

    Full Text Available BACKGROUND: Over the last decade, health, nutrition and policy experts have become increasingly aware of the many ways in which food insecurity and HIV infection negatively impact and reinforce one another. In response, many organizations providing HIV care began supplying food aid to clients in need. Food supplementation, however, was quickly recognized as an unsustainable and incomplete intervention. Many HIV care organizations therefore developed integrated HIV and livelihood programs (IHLPs to target the root causes of food insecurity. METHODS AND FINDINGS: We conducted a qualitative study using in-depth interviews with 21 key informants who worked at seven organizations providing HIV care, food aid, or IHLPs in Kampala, Uganda in 2007-2008 to better understand the impact of IHLPs on the well-being of people living with HIV and AIDS (PLWHAs and the challenges in transitioning clients from food aid to IHLPs. There was strong consensus among those interviewed that IHLPs are an important intervention in addressing food insecurity and its adverse health consequences among PLWHAs. Key informants identified three main challenges in transitioning PLWHAs from food supplementation programs to IHLPs: (1 lack of resources (2 timing of the transition and (3 logistical considerations including geography and weather. Factors seen as contributing to the success of programs included: (1 close involvement of community leaders (2 close ties with local and national government (3 diversification of IHLP activities and (4 close integration with food supplementation programs, all linked through a central program of HIV care.

    There has been a surge of interest in the development of nanoscale systems for the encapsulation, protection, and delivery of lipophilic nutrients, vitamins, and nutraceuticals. This review article highlights the challenges associated with incorporating these lipophilic bioactive components into foods, and then discusses potential nanoscale delivery systems that can be used to overcome these challenges. In particular, the desirable characteristics required for any nanoscale delivery system are presented, as well as methods of fabricating them and of characterizing them. An overview of different delivery systems is given, such as microemulsions, nanoemulsions, emulsions, microgels, and biopolymer nanoparticles, and their potential applications are discussed. Nanoscale delivery systems have considerable potential within the food industry, but they must be carefully formulated to ensure that they are safe, economically viable, and effective. Nanoscale delivery systems have numerous potential applications in the food industry for encapsulating, protecting, and releasing bioactive agents, such as nutraceuticals and vitamins. This review article highlights methods for designing, fabricating, characterizing, and utilizing edible nanoparticles from a variety of different food-grade ingredients. © 2015 Institute of Food Technologists®

    The meaningful involvement of women living with HIV/AIDS (MIWA) is a key feature of women-centred HIV care, yet little is known about transforming MIWA from principle to practice. Drawing on focus group data from the Canadian HIV Women's Sexual and Reproductive Health Cohort Study (CHIWOS), we explored HIV-positive women's meaningful involvement in the design and delivery of HIV/AIDS services in British Columbia, Canada. In this article, we highlight the benefits and tensions that emerge as women traverse multiple roles as service users and service providers within their care communities, and the impact this has on their access to care and overall health.

    Climate change impacts are expected to produce more frequent, longer and unpredictable drought periods with further saltwater intrusion in the Marshall Islands. As a result, a significant return to traditional food cropping is unlikely. This will lead to an increased dependence on food aid, especially in the outer atoll populations. An examination of the nutritional content of food aid suggests it is likely to lead to poor health outcomes. Dependence on food aid has gradually increased over the past 70 years in the Marshall Islands, starting with population relocation because of war and nuclear testing and most recently because of climate change. The authors argue that the health impacts of the supplemental imported diet, combined with migration to population centers, may result in an even greater prevalence of chronic diseases, and exert pressures that lead to more communicable disease, further exacerbating the syndemics in the Marshall Islands. The authors conclude that food aid donors and the Republic of the Marshall Islands (RMI) government have human rights obligations to ensure that the people in the Marshall Islands have access to adequate nutrition. Accordingly, donors and the government should re-examine the content of food and ensure it is of sufficient quality to meet the right to health obligations.

    Food insecurity, which affects >1 billion people worldwide, is inextricably linked to the HIV epidemic. We present a conceptual framework of the multiple pathways through which food insecurity and HIV/AIDS may be linked at the community, household, and individual levels. Whereas the mechanisms through which HIV/AIDS can cause food insecurity have been fairly well elucidated, the ways in which food insecurity can lead to HIV are less well understood. We argue that there are nutritional, mental health, and behavioral pathways through which food insecurity leads to HIV acquisition and disease progression. Specifically, food insecurity can lead to macronutrient and micronutrient deficiencies, which can affect both vertical and horizontal transmission of HIV, and can also contribute to immunologic decline and increased morbidity and mortality among those already infected. Food insecurity can have mental health consequences, such as depression and increased drug abuse, which, in turn, contribute to HIV transmission risk and incomplete HIV viral load suppression, increased probability of AIDS-defining illness, and AIDS-related mortality among HIV-infected individuals. As a result of the inability to procure food in socially or personally acceptable ways, food insecurity also contributes to risky sexual practices and enhanced HIV transmission, as well as to antiretroviral therapy nonadherence, treatment interruptions, and missed clinic visits, which are strong determinants of worse HIV health outcomes. More research on the relative importance of each of these pathways is warranted because effective interventions to reduce food insecurity and HIV depend on a rigorous understanding of these multifaceted relationships.

    HIV/AIDS and food insecurity are two of the leading causes of morbidity and mortality in sub-Saharan Africa, with each heightening the vulnerability to, and worsening the severity of, the other. Less research has focused on the social determinants of food insecurity in resource-limited settings, including social support and HIV-related stigma. In this study, we analyzed data from a cohort of 456 persons from the Uganda AIDS Rural Treatment Outcomes study, an ongoing prospective cohort of persons living with HIV/AIDS (PLWHA) initiating HIV antiretroviral therapy in Mbarara, Uganda. Quarterly data were collected by structured interviews. The primary outcome, food insecurity, was measured with the Household Food Insecurity Access Scale. Key covariates of interest included social support, internalized HIV-related stigma, HIV-related enacted stigma, and disclosure of HIV serostatus. Severe food insecurity was highly prevalent overall (38%) and more prevalent among women than among men. Social support, HIV disclosure, and internalized HIV-related stigma were associated with food insecurity; these associations persisted after adjusting for household wealth, employment status, and other previously identified correlates of food insecurity. The adverse effects of internalized stigma persisted in a lagged specification, and the beneficial effect of social support further persisted after the inclusion of fixed effects. International organizations have increasingly advocated for addressing food insecurity as part of HIV/AIDS programming to improve morbidity and mortality. This study provides quantitative evidence on social determinants of food insecurity among PLWHA in resource-limited settings and suggests points of intervention. These findings also indicate that structural interventions to improve social support and/or decrease HIV-related stigma may also improve the food security of PLWHA. Copyright © 2011 Elsevier Ltd.

    2017-09-01

    This study explored the food challenges facing people living with HIV/AIDS in Tsholotsho, Zimbabwe. Tsholotsho is a socio-economically disadvantaged, rural district in Zimbabwe and has one of the highest HIV prevalence rates in the country. For this study, face to face in-depth interviews were held with men and women living with HIV/AIDS. The findings of the study indicate that the economic situation in the country coupled with the lack of adequate rainfall has posed challenges to the ability of HIV/AIDS patients to maintain a healthy diet. In addition, there were concerns about the departure of non-government organisations which used to provide them with food parcels. The interviews also reveal that indigenous foods are being replaced by processed foods that are less healthy. Lack of employment opportunities and safety networks were some of the other factors leading them to experience food challenges in their everyday lives particularly in terms of access. As food security and good nutrition are key for maintaining physical and emotional health, the cumulative effects of these factors create a difficult environment to access food.

  1. Filamentous fungi for production of food additives and processing aids.

    Archer, David B; Connerton, Ian F; MacKenzie, Donald A

    2008-01-01

    Filamentous fungi are metabolically versatile organisms with a very wide distribution in nature. They exist in association with other species, e.g. as lichens or mycorrhiza, as pathogens of animals and plants or as free-living species. Many are regarded as nature's primary degraders because they secrete a wide variety of hydrolytic enzymes that degrade waste organic materials. Many species produce secondary metabolites such as polyketides or peptides and an increasing range of fungal species is exploited commercially as sources of enzymes and metabolites for food or pharmaceutical applications. The recent availability of fungal genome sequences has provided a major opportunity to explore and further exploit fungi as sources of enzymes and metabolites. In this review chapter we focus on the use of fungi in the production of food additives but take a largely pre-genomic, albeit a mainly molecular, view of the topic.

    Nature is a rich source of bioactive phytochemicals. These plant based compounds have rich scope as antioxidants, antimicrobial compounds and food preservatives and so for long time to be used in meat, fruits, vegetables and processed food items, either as added preservative or as coating material in various food applications, but the major limitation is their limited solubility in a food grade medium. Nano-emulsion is a best choice as a medium having vast area of application. The major advantage of nano-emulsion would be the solubility of a vast group of compounds, due to the presence of water and lipid phases. In this way, nano-emulsions can be proved to be the most suitable candidate as phytochemical delivery system for food preservation. In present article, the use of phytochemicals as potent food preservatives has been reviewed, in context of solubility of phytochemicals in nano-emulsion and applications of food grade nano-emulsions to food systems.

    Probiotics are live bacteria which have frequently been reported to be beneficial in preventing a wide range of diseases as well as playing a major role in treating the existing ailments. Thus far, a variety of probiotic products have been developed which can be categorized into two groups: probiotic foods and supplements. Both foods and supplements have been able to confer the health benefits claimed for them. However, it is not known which one can be clinically more efficient, and to the best of our knowledge, until now no research has been conducted to investigate this issue. The present review aims to discuss this matter, based on the evidence available in the literature. To do so, articles indexed in PubMed and ScienceDirect between 2000 and 2011 were reviewed. The articles included the clinical trials in which either foods or supplements were used to administer the probiotics to either patients suffering from different diseases or healthy subjects. Although both foods and supplements seem to have been efficient carriers for the beneficial bacteria, to generally promote public health in communities, probiotic foods appear to be preferred to probiotic supplements.

    Randomized controlled trials show that patient decision aids (DAs) can promote shared decision making and improve decision quality. Despite this evidence, integration of DAs into routine clinical practice has proceeded slowly. To identify factors that promote or impede integrating DAs into clinical practice in a large health care delivery system. Mixed-methods case study. Group Health, an integrated health plan and care delivery system in Washington state. Intervention. The project was carried out in 6 specialty service lines using 12 video-based DAs for preference-sensitive conditions related to elective surgical procedures. Process data, site visits, meeting observations, and in-depth interviews conducted with clinical staff, project staff, and health plan leaders in 2009 and 2010. The project established systemwide and clinic-specific processes that facilitated the distribution of approximately 10,000 DAs over 2 years. Several factors were identified as important for success in this implementation, including strong support from senior leaders, establishing a system for previsit ordering and providing timely feedback to teams about distribution rates, engaging providers and staff in development of the implementation process, and finding ways to address concerns about conditions that were perceived as life-threatening and/or time sensitive. Limitations included lack of data on patient perspectives, an implementation setting with salaried providers, and frontline provider interviews conducted in only selected service lines. With strong leadership, financial support, and a well-defined implementation strategy, 12 video-based DAs in 6 specialty service lines were integrated into routine practice over 2 years. Findings from this demonstration may advance the ability of other organizations to use DAs effectively and promote widespread adoption of shared decision making in routine patient care.

    2017-08-15

    Functional ingredients can be encapsulated by various wall materials for controlled release in food and digestion systems. Starch, as one of the most abundant natural carbohydrate polymers, is non-allergenic, GRAS, and cheap. There has been increasing interest of using starch in native and modified forms to encapsulate food ingredients such as flavours, lipids, polyphenols, carotenoids, vitamins, enzymes, and probiotics. Starches from various botanical sources in granular or amorphous forms are modified by chemical, physical, and/or enzymatic means to obtain the desired properties for targeted encapsulation. Other wall materials are also employed in combination with starch to facilitate some types of encapsulation. Various methods of crafting the starch-based encapsulation such as electrospinning, spray drying, antisolvent, amylose inclusion complexation, and nano-emulsification are introduced in this mini-review. The physicochemical and structural properties of the particles are described. The encapsulation systems can positively influence the controlled release of food ingredients in food and nutritional applications. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Micro- and nanoencapsulation is an emerging technology in the food field that potentially allows the improvement of food quality and human health. Bio-based delivery systems of bioactive compounds have a wide variety of morphologies that influence their stability and functional performance. The incorporation of bioactive compounds in food products using micro- and nano-delivery systems may offer extra health benefits, beyond basic nutrition, once their encapsulation may provide protection against undesired environmental conditions (e.g., heat, light and oxygen) along the food chain (including processing and storage), thus improving their bioavailability, while enabling their controlled release and target delivery. This review provides an overview of the bio-based materials currently used for encapsulation of bioactive compounds intended for food applications, as well as the main production techniques employed in the development of micro- and nanosystems. The behavior of such systems and of bioactive compounds entrapped into, throughout in vitro gastrointestinal systems, is also tracked in a critical manner. Comparisons between various in vitro digestion systems (including the main advantages and disadvantages) currently in use, as well as correlations between the behavior of micro- and nanosystems studied through in vitro and in vivo systems were highlighted and discussed here for the first time. Finally, examples of bioactive micro- and nanosystems added to food simulants or to real food matrices are provided, together with a revision of the main challenges for their safe commercialization, the regulatory issues involved and the main legislation aspects.

  14. HIV/AIDS, artisanal fishing and food security in the Okavango Delta, Botswana

    Science.gov (United States)

    Ngwenya, B. N.; Mosepele, K.

    Generally, rural households pursue all year round natural and non-natural resource-based livelihood systems to diversify these options in order to cope with risks emanating from a range of shocks and stressors. Artisanal fishing in the Delta is not only a major livelihood option but also a source of food security. This paper is based on analysis of primary data collected from a survey of 248 subsistence fishers’ households through simple random sampling in 22 villages in the Delta. The overall objectives of the survey were to assess the general prevalence of HIV/AIDS in the Ngamiland district of Botswana, to investigate potential effects of AIDS-related stressors, particularly chronic illness on artisanal fishing activities, and to assess implications towards food security. Results from this study indicate that HIV prevalence rates for pregnant women attending antenatal clinics in the Delta are approximately 30% and are related to factors such as marriage, education, and employment. Despite this relatively high prevalence percentage, most of the affected households do not have adequate access to HIV/AIDS support facilities. Support services are provided on the basis of population size and/or status of the settlement (i.e. urban, urban village, rural or remote). Therefore, since about 50% of the Delta’s population lives in settlements of less than 500 people, they receive health services indirectly through major population centres whose capacity to deliver timely HIV/AIDS services is limited. This disproportionate access to HIV/AIDS services disadvantages the majority of fishing communities in the Delta, and may affect their ability to fish. Moreover, about 53% of sampled households had cared for a continuously ill person/s (CIP’s) in the last 5 years, out of which approximately 29% felt that this seriously impacted fishing activities. These serious impacts included sale of family assets, depletion of savings, and switching or abandoning fishing activities

    A range of compounds with negative nutritional impact - 'anti-nutrients' - are found in most plant foods. The contents of anti-nutrients in processed foods depend on the ingredients and processing. Anti-nutrients in complementary foods for children can have a negative impact on nutritional status. The aim of this study was to screen complementary foods from developing countries for the anti-nutritional compounds, phytate, polyphenols, inhibitors of trypsin and chymotrypsin, and lectins. Commercial products based on whole grain cereals were included as a 'worst-case' scenario for anti-nutrient exposure in Europe. Contents of minerals (iron, zinc and calcium), in which absorption or utilisation is affected by anti-nutrients, were analysed. Thirty-six products representing foods used in food aid programmes, local blended foods, fortified instant porridges and 'baby foods' were analysed. The content of minerals indicated that the fortification of a number of products did not meet the declared levels of iron, zinc and calcium. The phytate content ranged from 68 to 1536 mg/100 g, confirming a persistent problem of high levels of phytate in processed cereal- and legume-based products. The phytate : Fe molar ratio exceeded the recommended level of <1.0 in 32 of the 36 products. The total polyphenols varied from 1.3 to 9.3 mg gentisic acid equivalents g(-1) . Screening low-molecular weight soluble polyphenols may be more relevant in complementary foods than total polyphenolic compounds. Trypsin and chymotrypsin inhibitors and lectins were found in residual amounts in most products, indicating efficient degradation by heat processing. However, young infants and malnourished children may have reduced pancreatic function, and upper limits for residual trypsin inhibitors are needed. © 2012 Blackwell Publishing Ltd.

    The goal of this study was to investigate the behaviour of rainbow trout ( n=30), Oncorhynchus mykiss, in small raceways when either self-feeders (T2) or hand-feeding (t2) were used. The method of food delivery in T2 was defensible while that of t2 was indefensible. Fish in both raceways were subjected to restricted feeding (RF) for 25 days. Food was available in the morning (09:00-10:00) in the downstream area and in the afternoon (16:00-17:00) in the upstream area of the raceways. The results showed that the behaviour of rainbow trout was significantly different under interference competition (T2) for food compared with that under scramble competition (t2). RF in T2 fish limited food availability to meal times when feeding rewards were available while t2 fish only responded to the location of food delivery. The aggressive fish in T2 were dominant, and t2 fish at high densities showed intense social interactions under the indefensible pattern of food distribution; these interactions did not dampen to a minimum level to suppress the development of dominance hierarchies. Further, the stocking density did not break down the dominance hierarchies between the T2 fish. This suggests that decreased efficiency in the search for food or inefficient foraging, induced by interference competition at high densities, affected the behaviour of rainbow trout.

    Genetically modified (GM) foods have caused much controversy. Construction of a food-grade delivery system is a desirable technique with presumptive impact on industrial applications from the perspective of bio-safety. The aim of this study was to construct a food-grade delivery system for Saccharomyces cerevisiae and to study the expression of monellin from the berries of the West African forest plant Dioscoreophyllum cumminsii in this system. A food-grade system for S. cerevisiae was constructed based on ribosomal DNA (rDNA)-mediated homologous recombination to enable high-copy-number integration of the expression cassette inserted into the rDNA locus. A copper resistance gene (CUP1) was used as the selection marker for yeast transformation. Because variants of transformants containing different copy numbers at the CUP1 locus can be readily selected after growth in the presence of elevated copper levels, we suggest that this system would prove useful in the generation of tandemly iterated gene clusters. Using this food-grade system, a single-chain monellin gene was heterologously expressed. The yield of monellin reached a maximum of 675 mg L(-1) . This system harbors exclusively S. cerevisiae DNA with no antibiotic resistance genes, and it should therefore be appropriate for safe use in the food industry. Monellin was shown to be expressed in this food-grade delivery system. To our knowledge, this is the first report so far on expression of monellin in a food-grade expression system in S. cerevisiae. © 2014 Society of Chemical Industry.

    Few studies in Europe have examined the relationship of sociodemographic and economic factors with diet in deprived populations. We analysed the association between socioeconomic characteristics and consumption of different food groups in food aid users. A cross-sectional study was conducted among food aid users in four urban French zones (n=1664). Associations of sociodemographic and economic factors and food aid use with frequency of consumption of the main food groups were tested using multivariate logistic regression models accounting for sampling weights. Both migrant status and consumption of fewer than three daily meals were associated with risk of low frequency of starchy food consumption (status was also associated with low frequency of consumption of fruits and vegetables (food insufficiency were more likely to be low consumers of fruits and vegetables, meat, seafood and eggs (food budget, temporary housing in a shelter and no source of household income were all associated with risk of low frequency of seafood consumption (food aid use, type of food aid distribution and perception of poor health status were associated with low consumption of meat, seafood and eggs. Economic level and other social characteristics were associated with an unhealthy diet within this deprived French population.

    Food aid provided by the United States has saved lives for almost two centuries. Delivering the right products is important, but of equal concern are the ways in which products are delivered and to whom. The study addresses how food products are currently used, whether interventions are appropriate to achieve nutrition objectives, and whether nutrition targets could be met more cost-effectively with a different mix of products or programs. The team conducted consultations with a broad range of stakeholders. A survey of Title II implementing partners was conducted, focusing on procurement and logistics, and uses of FBFs and other foods. Input of implementing partners, civil society, and donor organizations was obtained through individual consultations, international and small group meetings. More than 400 individuals accessed the project's website. The project convened a panel of experts in food technology and science, food policy, law, industry, medicine, development and humanitarian work, and the maritime industry, and held regular joint meetings with USDA and USAID. The draft report was widely disseminated and posted on the website. There is wide variation in the quantities of fortified blended foods provided to target populations. Most of these foods are used in health/nutrition programs, but they are also used in general family rations or as an incentive or pay. Clearer programming guidance and improved decision tools are needed to match products to nutrition goals, and programs should consider delivering nutrients across a basket of commodities, not single products. The evidence base for the effectiveness and cost-effectiveness of specific foods and programs needs to be strengthened and should be supported by FFP Research is needed to provide guidance on nutrition support for HIV/AIDS. Additional investments are needed in effective behavior change communication.

    Current micronutrient levels in Public Law 480 fortified blended foods (FBF) may not be appropriate for all food aid beneficiaries, particularly infants and/or young children and pregnant and/or lactating women. A simulation model was developed to determine the micronutrient fortification levels to include in FBF for food aid programs with the goal of reducing the risk of inadequate micronutrient intakes without exceeding the tolerable upper intake level (UL) for any recipient group. For each micronutrient, the age and gender group with the highest daily Recommended Nutrient Intake (RNI) relative to energy requirement was identified and the effect of providing different percentages of that RNI (66, 75, and 100%) was simulated. In this modeling exercise, we also examined consumption of the FBF at 25 (the usual level), 50, and 100% of daily energy requirement. Results indicated that 2 FBF products are needed: a complementary food for age 6-36 mo and a supplementary food for the older groups. Both of the FBF could be fortified to supply at least 75% of the RNI to all groups, without exceeding the UL for most nutrients, if consumed at 25% of the energy requirement. Even if consumed at 50% of energy requirements, mean intakes of most micronutrients would not exceed the UL, although at 100% of the energy requirement, several micronutrients were undesirably high. We conclude that fortifying an FBF to provide 75% of the RNI would be appropriate for most micronutrients, but this level of fortification would not be appropriate for long-term consumption of the FBF at 100% of the energy requirements.

    Portion size education tools, aids and interventions can be effective in helping prevent weight gain. However consumers have difficulties in estimating food portion sizes and are confused by inconsistencies in measurement units and terminologies currently used. Visual cues are an important mediator of portion size estimation, but standardized measurement units are required. In the current study, we present a new food volume estimation tool and test the ability of young adults to accurately quantify food volumes. The International Food Unit™ (IFU™) is a 4x4x4 cm cube (64cm 3 ), subdivided into eight 2 cm sub-cubes for estimating smaller food volumes. Compared with currently used measures such as cups and spoons, the IFU™ standardizes estimation of food volumes with metric measures. The IFU™ design is based on binary dimensional increments and the cubic shape facilitates portion size education and training, memory and recall, and computer processing which is binary in nature. The performance of the IFU™ was tested in a randomized between-subject experiment (n = 128 adults, 66 men) that estimated volumes of 17 foods using four methods; the IFU™ cube, a deformable modelling clay cube, a household measuring cup or no aid (weight estimation). Estimation errors were compared between groups using Kruskall-Wallis tests and post-hoc comparisons. Estimation errors differed significantly between groups (H(3) = 28.48, p estimations were most accurate in the group using the IFU™ cube (Mdn = 18.9%, IQR = 50.2) and least accurate using the measuring cup (Mdn = 87.7%, IQR = 56.1). The modelling clay cube led to a median error of 44.8% (IQR = 41.9). Compared with the measuring cup, the estimation errors using the IFU™ were significantly smaller for 12 food portions and similar for 5 food portions. Weight estimation was associated with a median error of 23.5% (IQR = 79.8). The IFU™ improves volume estimation accuracy compared to other methods. The

    The U.S. is the main country in the world that delivers its food assistance primarily via transoceanic shipments of commodity-based in-kind food. This approach is costlier and less timely than cash-based assistance, which includes cash transfers, food vouchers, and local and regional procurement, where food is bought in or nearby the recipient country. The U.S.'s approach is exacerbated by a requirement that half of its transoceanic food shipments need to be sent on U.S.-flag vessels. We estimate the effect of these U.S. food assistance distribution policies on child mortality in northern Kenya by formulating and optimizing a supply chain model. In our model, monthly orders of transoceanic shipments and cash-based interventions are chosen to minimize child mortality subject to an annual budget constraint and to policy constraints on the allowable proportions of cash-based interventions and non-US-flag shipments. By varying the restrictiveness of these policy constraints, we assess the impact of possible changes in U.S. food aid policies on child mortality. The model includes an existing regression model that uses household survey data and geospatial data to forecast the mean mid-upper-arm circumference Z scores among children in a community, and allows food assistance to increase Z scores, and Z scores to influence mortality rates. We find that cash-based interventions are a much more powerful policy lever than the U.S.-flag vessel requirement: switching to cash-based interventions reduces child mortality from 4.4% to 3.7% (a 16.2% relative reduction) in our model, whereas eliminating the U.S.-flag vessel restriction without increasing the use of cash-based interventions generates a relative reduction in child mortality of only 1.1%. The great majority of the gains achieved by cash-based interventions are due to their reduced cost, not their reduced delivery lead times; i.e., the reduction of shipping expenses allows for more food to be delivered, which reduces

    Introduction The increasing proportion of women living with HIV has evoked calls for tailored services that respond to women's specific needs. The objective of this investigation was to explore the concept of women-specific HIV/AIDS services to identify and define what key elements underlie this approach to care. Methods A comprehensive review was conducted using online databases (CSA Social Service Abstracts, OvidSP, Proquest, Psycinfo, PubMed, CINAHL), augmented with a search for grey literature. In total, 84 articles were retrieved and 30 were included for a full review. Of these 30, 15 were specific to HIV/AIDS, 11 for mental health and addictions and four stemmed from other disciplines. Results and discussion The review demonstrated the absence of a consensual definition of women-specific HIV/AIDS services in the literature. We distilled this concept into its defining features and 12 additional dimensions (1) creating an atmosphere of safety, respect and acceptance; (2) facilitating communication and interaction among peers; (3) involving women in the planning, delivery and evaluation of services; (4) providing self-determination opportunities; (5) providing tailored programming for women; (6) facilitating meaningful access to care through the provision of social and supportive services; (7) facilitating access to women-specific and culturally sensitive information; (8) considering family as the unit of intervention; (9) providing multidisciplinary integration and coordination of a comprehensive array of services; (10) meeting women “where they are”; (11) providing gender-, culture- and HIV-sensitive training to health and social care providers; and (12) conducting gendered HIV/AIDS research. Conclusions This review highlights that the concept of women-specific HIV/AIDS services is a complex and multidimensional one that has been shaped by diverse theoretical perspectives. Further research is needed to better understand this emerging concept and ultimately

    Protein quality scores use the amino acid (AA) requirements of a healthy North American child. AA requirements vary with physiologic status. We estimated AA requirements for healthy North American children, children with environmental enteric dysfunction, children recovering from wasting, and children with an acute infection. The protein quality of food aid products was then calculated to determine whether it was sufficient in all these groups, and we found that it may not be adequate for all of them. Physiologic status is important when assessing the protein quality of food aid. Rates of weight gain from 8 published trials treating children with moderate acute malnutrition were abstracted, and protein quality scores from the corresponding food aid products were calculated with the use of the digestible indispensable amino acid score (DIAAS). Two DIAAS values were calculated, one in healthy children aged 1-3 y as a reference population and the other in malnourished children aged 1-3 y as a reference population. These data were used to calculate the best fit regression line between weight gain and protein quality. The slope of the regression line was greater when malnourished children were used as a reference population than when healthy children were used (0.128; 95% CI: 0.118, 0.138 compared with 0.097; 95% CI: 0.090, 0.105 measured in g · kg -1 · d -1 · DIASS U -1 ). These findings suggest that adjusting AA requirements for physiologic status may more accurately estimate the minimum protein quality of food aid products. © 2017 American Society for Nutrition.

    Delivery by Cesarean section (CS) may predispose to allergic disorders, presumably due to alterations in the establishment of normal gut microbiota in early infancy. In this study, we sought to investigate the association between CS and physician-diagnosed food allergy and atopic dermatitis during the first 3 years of life, using data from a homogeneous, population-based, birth cohort. A total of 459 children born and cared for in the same tertiary maternity unit were examined at birth and followed up at 1, 6, 12, 18, 24, 30 and 36 months of age. Participants with symptoms suggestive of food allergy or atopic dermatitis were evaluated by a pediatric allergy specialist to confirm the diagnosis based on well-defined criteria. The rate of CS was 50.8% (n = 233). Food allergy was diagnosed in 24 participants (5.2%) while atopic dermatitis was diagnosed in 62 children (13.5%). Cesarean section (OR 3.15; 95% CI 1.14-8.70), atopic dermatitis of the child (OR 3.01; 95% CI 1.18-7.80), parental atopy (OR 4.33; 95% CI 1.73-12.1), and gestational age (OR 1.57; 95% CI 1.07-2.37) were significant and independent predictors of food allergy. Children with at least one allergic parent delivered by CS had higher probability of developing food allergy compared with vaginally delivered children of non-allergic parents (OR 10.0; 95% CI 3.06-32.7). Conversely, the effect of CS on atopic dermatitis was not significant (OR 1.35; 95% CI 0.74-2.47). Delivery by CS predisposes to the development of food allergy but not atopic dermatitis in early childhood. Cesarean section delivery seems to upregulate the immune response to food allergens, especially in children with allergic predisposition. © 2016 John Wiley & Sons A/S.

    In recent years there has been an increasing interest in the development of new and efficient oral food delivery systems as tools to prevent disease and promote human health and well-being. Such vehicles are sought to protect bioactive ingredients added to food while controlling and targeting their release as they pass through the human gastrointestinal tract (GIT). This review aims to summarize the key concepts of food delivery systems, their characterization and evaluation. Particularly, evaluation of their performance within the human GIT is discussed. To this end an overview of several in vivo and in vitro methods currently applied for the study of such systems is given. Although considered to be still in its infancy, this promising field of research is likely to infiltrate into real products through rational design. In order for such efforts to materialize into real products some challenges still need to be met and are discussed herein. Overall, it seems that adopting a comprehensive pharmacological approach and relevant cutting edge tools are likely to facilitate innovations and help elucidate and perhaps tailor delivery systems' behavior in the human GIT.

  12. Conceptualizing the cross-cultural gaps in managing international aid: HIV/AIDS and TB project delivery in Southern Africa.

    Jackson, Terence

    2011-01-01

    There appears to be a gap between the billions of dollars inputted into fighting HIV/AIDS and TB and outcomes. This in part can be attributed to the lack of attention in International Development to managing programmes and projects within complex levels of cross-cultural interactions. International Development often ignores management issues, yet Management Studies is left wanting through a lack of engagement with development issues including the fight against disease and poverty. This paper attempts to link these two disciplines towards mutual benefit, through a critical cross-cultural approach. It provides contextualization of international development policies/strategies; conceptualization of dominant paradigms; structural analysis of how a programme/project fits into the global governance structure; analysis of complexities and levels of cross-cultural interaction and their consequences and the process and implications of knowledge transfer across cultural distances. It concludes with implications for policy and practice, as well as what is needed from cross-disciplinary research. This includes how feedback loops can be strengthened from local to global, how indigenous knowledge may be better understood and integrated, how power relations within the global governance structure could be managed, how cross-cultural interaction could be better understood, and how knowledge transfer/sharing should be critically managed.

    2017-06-01

    Advances in continuous glucose monitoring (CGM) have brought on a paradigm shift in the management of type 1 diabetes. These advances have enabled the automation of insulin delivery, where an algorithm determines the insulin delivery rate in response to the CGM values. There are multiple automated insulin delivery (AID) systems in development. A system that automates basal insulin delivery has already received Food and Drug Administration approval, and more systems are likely to follow. As the field of AID matures, future systems may incorporate additional hormones and/or multiple inputs, such as activity level. All AID systems are impacted by CGM accuracy and future CGM devices must be shown to be sufficiently accurate to be safely incorporated into AID. In this article, we summarize recent achievements in AID development, with a special emphasis on CGM sensor performance, and discuss the future of AID systems from the point of view of their input-output characteristics, form factor, and adaptability.

    Polymers intended for food contact use have been analysed for organic residues which could be attributed to a range of substances employed as polymerization aids (e.g. initiators and catalysts). A wide range of polymers was extracted with solvents and the extracts analysed by gas chromatography mass spectrometry (GC-MS). The overwhelming majority of substances identified were not derived from aids to polymerization but were oligomers, additives and adventitious contaminants. However, a small number of substances were identified as initiator residues. These included tetramethylsuccinonitrile (TMSN) which was observed in two polymers and it derived from recombination of two azobisisobutyronitrile (AIBN) initiator radicals. Methyl benzoate, benzoic acid, biphenyl and phenyl benzoate were detected in one poly(methyl methacrylate) sample and in two polyvinylchlorides and they are thought to be derived from benzoyl peroxide initiator. TMSN was subsequently targeted for analysis of poly-(methyl methacrylate) plastics using proton nuclear magnetic resonance spectrometry (1H-NMR) and GC-MS. NMR detected the presence of cyanoisopropyl radical residues in the plastic at 470-3400 mg/kg whereas GC-MS detected TMSN at only 65-540 mg/kg in the samples. It is concluded that the bulk of cyanoisopropyl residues detected by NMR were either polymer-bound or were the products of side-reactions of the initiator radical. The migration of TMSN itself into the food simulants 3% aqueous acetic acid, 15% aqueous ethanol, and olive oil, at 40 degrees C for 10 days, was measured using GC-MS. Migration was very low with straw) and plastics intended for food contact and their potential for migration to foods is correspondingly low.

  16. Recent advances of resveratrol in nanostructured based delivery systems and in the management of HIV/AIDS.

    2014-11-28

    Resveratrol, a natural polyphenolic compound present in trees, in peanuts, in grapevines and exhibited multiple pharmacological activities. Extensive research in last two decades suggested that resveratrol possesses anti-inflammatory, anti-cancer, anti-viral, anti-amyloid, anti-arthritic and antioxidant properties. Some clinical reports have proposed that resveratrol might be a potential candidate for the prevention and/or treatment of HIV/AIDS and synergistically enhances the anti-HIV-1 activity. Resveratrol is not toxic to cells, and by itself reduces viral replication by 20% to 30%. With almost 12% of the world population suffering from HIV/AIDS including its resurgence in the developed world, better management of this global threat is highly desired. Further, various studies demonstrated several issues associated with resveratrol which account for its poor systemic bioavailability (almost zero) due to rapid and extensive first pass metabolism and existence of enterohepatic recirculation. In order to improve bioavailability and cellular uptake of resveratrol, various strategies have been adopted to date which includes resveratrol prodrug and the development of nanostructured delivery systems. Besides, nanostructured delivery systems are also known to inhibit the P-glycoprotein (P-gp) efflux, reduced metabolism by gut cytochrome P-450 enzymes, and circumnavigate the hepatic first-pass effect, facilitating absorption of drugs via intestinal lymphatic pathways. This review paper provides an updated bird's-eye view account on the publications and patents study on the recent novel approaches to deliver resveratrol in order to enhance oral bioavailability, overcome first pass metabolism and trounce enterohepatic recirculation to make resveratrol a therapeutically potent drug. Providing a relatively pithy overview, this paper thus presents recent advances of resveratrol for the treatment and prevention of HIV/AIDS. Copyright © 2014 Elsevier B.V. All rights reserved.

    Claeyé, Frederik; Jackson, Terence

    2011-01-01

    The purpose of this paper is to report the findings of a broad-based study that initially investigated a possible gap in global inputs into the fight against HIV/AIDS and TB co-infection, and outputs in terms of results achieved. It is proposed that such a gap may be hypothesized to be due, at least in part, to inappropriate management regimes within the global health governance structure. The research does not simply question the effectiveness of the management of programs and projects, but rather the inappropriateness resulting from the lack of addressing cross-cultural issues. The factors facilitating or hampering project service delivery were examined, by looking at 12 case studies in Botswana and South Africa. These data were complemented with seven semi-structured interviews with donor organizations and NGOs, conducted in the North. Cultural interactions were investigated by using the concept of "interfaces". The results suggest that there is a disjuncture between the global and local level that affects project delivery. The main issues hampering project outcomes can be summarized as systemic, structural and cultural. The article's main contributions are both theoretical, looking at global project delivery from a cross-cultural management perspective, as well as to development praxis by highlighting the need to focus more critically on cross-cultural management issues within the global health governance structure, and indeed within international development as a whole.

  18. Effects of Food Restriction and Sucrose Intake on Synaptic Delivery of AMPA Receptors in Nucleus Accumbens

    2011-01-01

    Insertion and removal of AMPA receptors from the synaptic membrane underlie dynamic tuning of synaptic transmission and enduring changes in synaptic strength. Preclinical addiction research suggests that AMPA receptor trafficking plays an important role in nucleus accumbens (NAc) neuroplasticity underlying the compulsive and persistent quality of drug-seeking. Considering the parallels between drug addiction and compulsive eating, plus the supranormal reward properties of sucrose, and the role of dieting as a risk factor in development of binge pathology, the present study used a biochemical subcellular fractionation approach to determine whether brief intake of a 10% sucrose solution increases synaptic delivery of AMPA receptors in NAc of chronically food-restricted (FR) relative to ad libitum fed (AL) rats. FR, alone, produced a small but significant increase in synaptic expression of AMPA receptors. This may contribute to NAc integrative mechanisms that mediate the enhanced behavioral responsiveness of FR subjects to phasic reward stimuli, including food and drugs. Brief intake of sucrose increased GluR1 in the PSD, regardless of dietary condition, though the net effect was greater in FR than AL subjects. A marked increase in GluR2 was also observed, but only in FR rats. This set of results suggests that in FR subjects, sucrose may have primarily increased delivery of GluR1/GluR2 heteromers to the PSD, while in AL subjects sucrose increased delivery of GluR2-lacking channels. The functional consequences of these possible differences in subunit composition of trafficked AMPA receptors between diet groups remain to be determined. Nevertheless, the present set of results suggest a promising new avenue to pursue in the effort to understand synaptic plasticity involved in adaptive and pathological food-directed behavior, and the mechanistic basis of severe dieting as a risk factor for the latter.

    2015-01-01

    Proteins can be used to fabricate nanoparticles and microparticles suitable for use as delivery systems for bioactive compounds in pharmaceutical, food, cosmetic, and other products. Food proteins originate from various animal or vegetal sources and exhibit a wide diversity of molecular and physicochemical characteristics, e.g., molecular weight, conformation, flexibility, polarity, charge, isoelectric point, solubility, and interactions. As a result, protein particles can be assembled using numerous different preparation methods, from one or more types of protein or from a combination of a protein and another type of biopolymer (usually a polysaccharide). The final characteristics of the particles produced are determined by the proteins and/or polysaccharides used, as well as the fabrication techniques employed. This chapter provides an overview of the functional properties of food proteins that can be used to assemble nanoparticles and microparticles, the fabrication techniques available to create those particles, the factors that influence their stability, and their potential applications within the food industry. © 2015 Elsevier Inc.

    β-Carotene has been widely investigated both in the industry and academia, due to its unique bioactive attributes as an antioxidant and pro-vitamin A. Many attempts were made to design delivery systems for β-carotene to improve its dispersant state and chemical stability, and finally to enhance the functionality. Different types of oil-in-water emulsions were proved to be effective delivery systems for lipophilic bioactive ingredients, and intensive studies were performed on β-carotene emulsions in the last decade. Emulsions are thermodynamically unstable, and emulsions with intact structures are preferable in delivering β-carotene during processing and storage. β-Carotene in emulsions with smaller particle size has poor stability, and protein-type emulsifiers and additional antioxidants are effective in protecting β-carotene from degradation. Recent development in the design of protein-polyphenol conjugates has provided a novel approach to improve the stability of β-carotene emulsions. When β-carotene is consumed, its bioaccessibility is highly influenced by the digestion of lipids, and β-carotene in smaller oil droplets containing long-chain fatty acids has a higher bioaccessibility. In order to better deliver β-carotene in complex food products, some novel emulsions with tailor-made structures have been developed, e.g., multilayer emulsions, solid lipid particles, Pickering emulsions. This review summarizes the updated understanding of emulsion-based delivery systems for β-carotene, and how emulsions can be better designed to fulfill the benefits of β-carotene in functional foods.

    2017-01-01

    Fortified complementary foods (FCF) and home fortificants - single-sachet micronutrient powders (MNP) or small-quantity lipid-based nutrient supplements (SQ-LNS) to be added to a child's food immediately before consumption - have been shown to be efficacious to improve the micronutrient status and some functional outcomes in children 6-23 months of age. The objective of this chapter is to describe and discuss the latest advances related to the composition and delivery of FCF products, including home and commercial fortification. For FCF and MNPs, there is guidance to ensure that products are safe and aligned with recommendations. Impact, however, can be achieved only if adequate attention is paid to program design and implementation, including the choice of the delivery platform, and ensuring availability, accessibility, acceptability, coverage, and utilization by the target population. Well-targeted programs such as social protection programs, health services, community-based vendors (referred to as market based), child health weeks, and emergency programs have all been used as delivery platforms for FCF and MNPs. To date, guidance for formulation and programmatic experience with the distribution of SQ-LNS is limited. An in-depth understanding of the local context and culture, and the design and implementation of program components, including behavior change interventions that respond to those, can increase program coverage and product utilization. Using rigorous process evaluation would permit to adapt programs to increase their potential for impact, strengthen the evidence related to how programs work, and allow the development of program guidance to increase effective implementation. © 2017 Nestec Ltd., Vevey/S.

    Full Text Available The storage of frequently requested multimedia content at small-cell base stations (BSs can reduce the load of macro-BSs without relying on high-speed backhaul links. In this work, the optimal operation of a system consisting of a cache-aided small-cell BS and a macro-BS is investigated for both offline and online caching settings. In particular, a binary fading one-sided interference channel is considered in which the small-cell BS, whose transmission is interfered by the macro-BS, has a limited-capacity cache. The delivery time per bit (DTB is adopted as a measure of the coding latency, that is, the duration of the transmission block, required for reliable delivery. For offline caching, assuming a static set of popular contents, the minimum achievable DTB is characterized through information-theoretic achievability and converse arguments as a function of the cache capacity and of the capacity of the backhaul link connecting cloud and small-cell BS. For online caching, under a time-varying set of popular contents, the long-term (average DTB is evaluated for both proactive and reactive caching policies. Furthermore, a converse argument is developed to characterize the minimum achievable long-term DTB for online caching in terms of the minimum achievable DTB for offline caching. The performance of both online and offline caching is finally compared using numerical results.

    Sonophoresis temporarily increases skin permeability such that medicine can be delivered transdermally. Cavitation is believed to be the predominant mechanism in sonophoresis. In this study, an ultrasound contrast agent (UCA) strategy was adopted instead of low frequency ultrasound to assure that cavitation occurred, and the efficacy of sonophoresis with UCA was quantitatively analyzed by optical measurements. The target drug used in this study was 0.1 % Definity(R) in 70% glycerol, which was delivered into porcine skin samples. Glycerol was used because it is an optical clearing agent, and the efficiency of glycerol delivery could be analyzed with optical measurements. The applied acoustic pressure was approximately 600 kPa at 1 MHz ultrasound with a 10% duty cycle for 60 minutes. Experimental results indicated that the measured relative contrast (RC) after sonophoresis with UCA was approximately 80% higher than RC after sonophoresis without UCA. In addition, the variance of RC was also reduced by more than 50% with the addition of a UCA. The use of a UCA appeared to increase cavitation, demonstrating that the use of a UCA can be effective in transdermal drug delivery (TDD).

    Household food availability is consistently linked to dietary intake; yet behavioral weight control treatment includes only minimal instruction on how to change the home environment to support dietary goals. This pilot study examined whether it is feasible to change the household food environments of behavioral weight loss participants through the use of a commercially available grocery home delivery service. Overweight participants (N = 28; BMI = 31.7 +/- 3.6 kg/m2; 89.3% women, 47.9 +/- 9.5 years) were randomly assigned to 8-weeks of standard behavioral weight loss (SBT) or to SBT plus home food delivery (SBT+Home). SBT+Home participants were instructed to do their household grocery shopping via an online service affiliated with a regional supermarket chain and were reimbursed for delivery charges. Compared to SBT, SBT+Home produced significantly greater reductions in the total number of foods in the home (p = .01) and number of foods that were high in fat (p = .002). While the groups did not differ in 8-week weight losses, within SBT+Home there was a trend for the number of home deliveries to be associated with weight loss (p = .08). Participants reported that the home delivery service was easy to use and that it helped decrease impulse purchases and lead to healthier choices; however, few planned to continue using the service after the study. Encouraging weight loss participants to use a commercially available online grocery ordering and home delivery service reduces the overall number of food items in the home and decreases access to high-fat food choices. More research is needed to determine whether this is a viable strategy to strengthen stimulus control and improve weight loss outcomes.

    The literature indicates that the health of women in Afghanistan is poor. In 1997 maternal mortality in Afghanistan was one of the worst in the world. Difficulties in establishing health services revolve around fundamentalist Islamic ideas and ongoing violence within Afghanistan. The literature holds advice on key behaviours for health professionals who may chose to work in Afghanistan. The literature also identifies the local level action that is occurring as the issue of women's health is recognised. Humanitarian assistance has been provided, with international aid agencies having to weigh the ethical responsibilities they hold and one agency tragically facing the violent loss of its own staff. Easy answers are not in the literature, merely an opportunity to understand, consider, and take action about what is facing women in Afghanistan and those who try to help.

  10. Phytosome and Liposome: The Beneficial Encapsulation Systems in Drug Delivery and Food Application

    2015-06-01

    Full Text Available Due to poor solubility in lipids, many of bioactive components (Nutraceutical materials show less bioactivity than optimal state in water solution. Phytosomes improve absorption and bioavailability of biomaterials. Liposomes, spherical shaped nanocarriers, were discovered in the 1960s by bangham. Due to their composition, variability and structural properties, liposomes and phytosomes are extremely versatile, leading to a large number of applications including pharmaceutical, cosmetics and food industrial fields. They are advanced forms of herbal formulations containing the bioactive phytoconstituents of herb extracts such as flavonoids, glycosides and terpenoids, which have good ability to transit from a hydrophilic environment into the lipid friendly environment of the outer cell membrane. They have better bioavailability and actions than the conventional herbal extracts containing dosage. Phytosome technology has increasing effect on the bioavailability of herbal extracts including ginkgo biloba, grape seed, green tea, milk thistle, ginseng, etc., and can be developed for various therapeutic uses or dietary supplements. Liposomes are composed of bilayer membranes, which are made of lipid molecules. They form when phospholipids are dispersed in aqueous media and exposed to high shear rates by using micro-fluidization or colloid mill. The mechanism for formation of liposomes is mainly the hydrophilic–hydrophobic interactions between phospholipids and water molecules. Here, we attempt to review the features of phytosomes and liposomes as well as their preparation methods and capacity in food and drug applications. Generally, it is believed that phytosomes and liposomes are suitable delivery systems for nutraceuticals, and can be widely used in food industry.

    The 6th international symposium in the series "Delivery of Functionality in Complex Food Systems: Physically inspired approaches from nanoscale to microscal" was held in the heart of Paris from 14 to 17 July, 2015. It brought together PhD students, academic food researchers and industrials from diversified food sectors. The scientific sessions of this meeting were constructed around important topics dealing with 1) Engineering of tailored-made structures in bio-based systems; 2) Complexity and emergent phenomena in the integrative food science; 3) Investigation of nano and microstructures in the bulk and at interfaces; 4) Modeling approaches from bio-molecules and matrix structures to functionality; 5) Tuning binding & release of bioactive compounds by matrix modulation, and finally; 6) Tuning the delivery of functionality to the body. These topics were selected to cover different scientific fields and to show the contribution of food physical structures to development of health- and plaisure-supporting food functions. The oral communications were all introduced by key note speakers and they were all illustrated by outstanding high quality short communications. One of the most original features of this symposium was the increasing number of presentations using multiscale and modeling approaches illustrating the concept of complexity and emergent phenomena integrative food science. These highlighted the importance of studies on interactions between structure properties of engineered delivery systems and human body (sensory properties, digestion, release, bioavailability and bioaccessibility).

    Depression is common among people living with HIV/AIDS and contributes to a wide range of worsened HIV-related outcomes, including AIDS-related mortality. Targeting modifiable causes of depression, either through primary or secondary prevention, may reduce suffering as well as improve HIV-related outcomes. Food insecurity is a pervasive source of uncertainty for those living in resource-limited settings, and cross-sectional studies have increasingly recognized it as a critical determinant of poor mental health. Using cohort data from 456 men and women living with HIV/AIDS initiating HIV antiretroviral therapy in rural Uganda, we sought to (a) estimate the association between food insecurity and depression symptom severity, (b) assess the extent to which social support may serve as a buffer against the adverse effects of food insecurity, and (c) determine whether the buffering effects are specific to certain types of social support. Quarterly data were collected by structured interviews and blood draws. The primary outcome was depression symptom severity, measured by a modified Hopkins Symptom Checklist for Depression. The primary explanatory variables were food insecurity, measured with the Household Food Insecurity Access Scale, and social support, measured with a modified version of the Functional Social Support Questionnaire. We found that food insecurity was associated with depression symptom severity among women but not men, and that social support buffered the impacts of food insecurity on depression. We also found that instrumental support had a greater buffering influence than emotional social support. Interventions aimed at improving food security and strengthening instrumental social support may have synergistic beneficial effects on both mental health and HIV outcomes among PLWHA in resource-limited settings.

    As mission distance and duration increase, the need grows for non-invasive disease prevention and immunomodulation, especially given the limited medical response capability expected for these missions and the immune dysregulation documented in crew. Additionally, changes in diet, lifestyle, antibiotic usage, and the environmental stresses during spaceflight may alter crewmembers' intestinal microbiome. The addition of probiotic bacteria to the space food system is expected to confer immunostimulatory benefits on crewmembers, with the potential to counteract the immune dysregulation that has been documented in spaceflight. Based on previous studies that demonstrated unique microbiological responses to the low shear environment of spaceflight, probiotic organisms hold the potential to induce enhanced beneficial responses through mechanisms, such as beneficial interactions with human immune cells and repression of colonization of pathogens on the mucosa. The work presented here will begin to address two research gaps related to providing probiotics in spaceflight: 1) delivery, and 2) the effect of the low shear microgravity environment on probiotic attributes. The probiotic Lactobacillus acidophilus was selected for investigation due to its wide commercial use and documented benefits that include inhibition of virulence related gene expression in pathogens and mucosal stimulation of immune cells. The delivery system for probiotics has not been determined for spaceflight, where the food system is shelf stable and the lack of refrigeration prevents the use of traditional dairy delivery methods. In order to demonstrate the potential of the space food system to deliver viable probiotic bacteria to crewmembers, the probiotic L. acidophilus was packaged in high barrier flight packaging in nonfat dry milk (NFDM) or retained in commercial capsule form. Viable cells were enumerated over 8 months of storage at 22, 4, and -80ºC. The survival of L. acidophilus rehydrated in NFDM

    As a preliminary experiment on new sanitizer delivery tools, the efficacy of aerosolized sanitizer on food-borne pathogens was investigated in larger model chamber system. Peroxyacetic acid and hydrogen peroxide were aerosolized in a model system against artificially inoculated target micro-organisms on laboratory media. Cultures of four different food-borne pathogens were inoculated and affixed onto three different heights (bottom, wall and ceiling), and three different orientations (face-down, vertical and face-down) inside a commercial semi-trailer cabinet (14.6 x 2.6 x 2.8 m). Sanitizer was aerosolized into 2 microm droplet size fog and treated for 1 h at ambient temperature. Populations of Bacillus cereus, Listeria innocua, Staphylococcus aureus, and Salmonella typhimurium were reduced by an average of 3.09, 7.69, 6.93 and 8.18 log units per plate respectively. Interestingly, L. innocua, Staph. aureus, and Salm. typhimurium showed statistically not different (P >/= 0.05) reduction patterns relative to height and orientation that were never expected in a spraying system. Aerosolized sanitizers diffuse like gaseous sanitizers. Aerosolization has great potential for use in commercial applications.

    Feature objects aided strategy was used to predict and evaluate the biomethane production of food waste and corn stalk anaerobic co-digestion. The kinetics of co-digestion and mono-digestion of food waste and/or corn stalk was also analyzed. The results indicated that the compositions of food waste and corn stalk were significantly different. The anaerobic digestion of three feature objects at different mixing ratios showed the different biomethane yields and kinetic constants. Food waste and corn stalk co-digestion enhanced the digestion rate and achieved 22.48% and 41.55% higher biomethane production than those of food waste and corn stalk mono-digestion, respectively.

    Full Text Available To date, treating vertical food impaction with open contact effectively, especially with an atraumatic therapy, remains a challenge. In this study, we developed a simple, atraumatic, and economic therapeutic measure to treat vertical food impaction. The scientific rationale of our therapeutic technique is to restore an intact and firm proximal contact with proper location and form relationships to prevent forceful interproximal wedging of food, which in turn protects interdental papilla. We performed the procedure using flowable composite resin or composite resin cement with the aid of a cerclage wire under tension to rebuild the contact area. The reported method is especially useful for some challenging clinical cases, such as food impaction after crown and inlay on onlay restoration, and some conventional treatment methods, such as contouring the marginal ridge and developmental grooves, are ineffective.

    A model based on feature objects (FOs) aided strategy was used to evaluate the methane generation from food waste by anaerobic digestion. The kinetics of feature objects was tested by the modified Gompertz model and the first-order kinetic model, and the first-order kinetic hydrolysis constants were used to estimate the reaction rate of homemade and actual food waste. The results showed that the methane yields of four feature objects were significantly different. The anaerobic digestion of homemade food waste and actual food waste had various methane yields and kinetic constants due to the different contents of FOs in food waste. Combining the kinetic equations with the multiple linear regression equation could well express the methane yield of food waste, as the R 2 of food waste was more than 0.9. The predictive methane yields of the two actual food waste were 528.22 mL g -1  TS and 545.29 mL g -1  TS with the model, while the experimental values were 527.47 mL g -1  TS and 522.1 mL g -1  TS, respectively. The relative error between the experimental cumulative methane yields and the predicted cumulative methane yields were both less than 5%. Copyright © 2017 Elsevier Ltd. All rights reserved.

  1. The delivery of organic contaminants to the Arctic food web: why sea ice matters.

    For decades sea ice has been perceived as a physical barrier for the loading of contaminants to the Arctic Ocean. We show that sea ice, in fact, facilitates the delivery of organic contaminants to the Arctic marine food web through processes that: 1) are independent of contaminant physical-chemical properties (e.g. 2-3-fold increase in exposure to brine-associated biota), and 2) depend on physical-chemical properties and, therefore, differentiate between contaminants (e.g. atmospheric loading of contaminants to melt ponds over the summer, and their subsequent leakage to the ocean). We estimate the concentrations of legacy organochlorine pesticides (OCPs) and current-use pesticides (CUPs) in melt pond water in the Beaufort Sea, Canadian High Arctic, in 2008, at near-gas exchange equilibrium based on Henry's law constants (HLCs), air concentrations and exchange dynamics. CUPs currently present the highest risk of increased exposures through melt pond loading and drainage due to the high ratio of melt pond water to seawater concentration (Melt pond Enrichment Factor, MEF), which ranges from 2 for dacthal to 10 for endosulfan I. Melt pond contaminant enrichment can be perceived as a hypothetical 'pump' delivering contaminants from the atmosphere to the ocean under ice-covered conditions, with 2-10% of CUPs annually entering the Beaufort Sea via this input route compared to the standing stock in the Polar Mixed Layer of the ocean. The abovementioned processes are strongly favored in first-year ice compared to multi-year ice and, therefore, the dynamic balance between contaminant inventories and contaminant deposition to the surface ocean is being widely affected by the large-scale icescape transition taking place in the Arctic.

    Food insecurity is a risk factor for both HIV transmission and worse HIV clinical outcomes. We examined the prevalence of and factors associated with food insecurity among homeless and marginally housed HIV-infected individuals in San Francisco recruited from the Research on Access to Care in the Homeless Cohort. We used multiple logistic regression to determine socio-demographic and behavioral factors associated with food insecurity, which was measured using the Household Food Insecurity Access Scale. Among 250 participants, over half (53.6%) were food insecure. Higher odds of food insecurity was associated with being white, low CD4 counts, recent crack use, lack of health insurance, and worse physical and mental health. Food insecurity is highly prevalent among HIV-infected marginally housed individuals in San Francisco, and is associated with poor physical and mental health and poor social functioning. Screening for and addressing food insecurity should be a critical component of HIV prevention and treatment programs.

    Green tea has been associated with the prevention and reduction of a wide range of severe health conditions such as cancer, immune, and cardiovascular diseases. The health benefits associated with green tea consumption have been predominantly attributed to green tea polyphenols. The functional properties of green tea polyphenols are mainly anti-oxidative, antimutagenic, anticarcinogenic, anti-microbial, etc. These excellent properties have recently gained considerable attention in the food industry. However, their application is limited by their sensitivity to factors like temperature, light, pH, oxygen, etc. More, studies have reported the occurrence of unpleasant taste and color transfer during food processing. Lastly, the production of functional food requires to maintain the stability, bioactivity, and bioavailability of the active compounds. To tackle these obstacles, technological approaches like microencapsulation have been developed and applied for the formulation of green tea-enriched food products. The present review discusses the novelty in microencapsulation techniques for the safe delivery of green tea polyphenols in food matrices. After a literature on the green tea polyphenols composition, and their health attributes, the encapsulation methods and the coating materials are presented. The application of green tea encapsulates in food matrices as well as their effect on food functional and sensory properties are also discussed. Copyright © 2017 Elsevier Ltd. All rights reserved.

  5. Costs of providing food assistance to HIV/AIDS patients in Sofala province, Mozambique: a retrospective analysis.

    Posse, Mariana; Baltussen, Rob

    2013-08-28

    As care and antiretroviral treatment (ART) for people living with HIV/AIDS become widely available, the number of people accessing these resources also increases. Despite this exceptional progress, the estimated coverage in low- and middle-income countries is still less than half of all people who need treatment. In addition, treatment discontinuation and non-adherence are still concerns for ART programs. Governments and partner institutions have sought to implement a variety of interventions addressing the main reasons behind the low coverage of, discontinuation of, and non-adherence to ART. Food assistance is one of those interventions; increasing evidence suggests that this type of intervention has the potential to improve ART outcomes. However, to our knowledge, no study has estimated its costs in detail. The objective of this study was to assess the costs of a program providing food assistance to HIV/AIDS patients in Sofala province, Mozambique, in 2009. We performed a retrospective analysis of the costs of providing food assistance, based on financial and economic costs. We used the ingredients approach to estimate costs, which involved multiplying the total estimated quantities of goods and services actually employed in providing the intervention by their respective unit prices. In 2009, the cost of providing food assistance to HIV/AIDS patients was $2.27 million, with capital and recurrent costs accounting for 1% and 99% of total costs, respectively. Food made up the largest component, at 49% of total costs. At 24%, transport operating costs were the second largest item. The cost per patient served was $288 over 3 months. The food distribution program carries significant costs. To assess whether it provides value for money, the present study results should be interpreted in conjunction with the program's impact, and in comparison with other programs that aim to improve adherence to ART. Our costing analysis revealed important management information

    Food insecurity is a considerable challenge in sub-Saharan Africa, disproportionately affecting persons living with HIV/AIDS. This study investigates the lived experience, determinants, and consequences of food insecurity and hunger among individuals living with HIV/AIDS on the shore of Lake Victoria in Suba District, Kenya. Parallel mixed methods included semi-structured interviews and administration of the Household Food Insecurity Access Scale among a systematic sample of 67 persons living with HIV/AIDS (49 of whom were receiving antiretroviral therapy [ART]). All respondents were either severely (79.1%) or moderately (20.9%) food insecure; no respondents were mildly food insecure or food secure. Qualitative data and simple and multiple linear regression models indicated that significant determinants of food insecurity include increased age, a greater number of children, and not being married. A number of themes related to food insecurity and ART emerged, including: (1) an increase in hunger or appetite since initiating ART; (2) exacerbation of ART-related side effects; and (3) non-adherence to ART due to hunger, food insecurity, or agricultural work responsibilities. HIV interventions should address food insecurity and hunger, particularly among at-risk populations, to promote ART adherence and better health outcomes.

    The prevalence of homelessness in the UK is rising, and demand for food aid through charitable meal services has increased. Charitable services make a substantial contribution to the food and nutrient intake of vulnerable people, and thus offer a platform for dietary improvement. This study examined food provision by a large charitable organisation in a major UK city. It had several objectives: Firstly to quantify nutritional composition of breakfast and lunch meals, secondly to understand factors that influence the composition of menus and meals, and thirdly to determine whether, within the context of these influences, improvements to the menu would be possible and whether these would be acceptable to clients. Mixed methods of ethnography, semi-structured interviews, quantitative nutrient analysis, recipe adaptation and taste tests were employed. The research team worked as volunteers in the organisation for a 3-week period and interviews were held with the kitchen staff. Food choice was recorded for 189 clients at breakfast and 251 clients at lunch over a 5-day period and nutrient content of these meals was estimated. Meals were weighted towards fat and sugar energy. Energy, potassium, calcium, vitamin C, vitamin A, zinc and magnesium content of meals were below Dietary Reference Value (DRV) targets for at least 20% of breakfast and lunch meals. Such inadequacies may be addressed by the addition of simple foods to the breakfast menu and adaptation of lunchtime recipes. Twelve lunchtime dishes were proposed and eight of these were seemingly acceptable to clients in taste testing. Barriers to provision of healthier meals include budget, food donations and acceptability of meals. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Full Text Available A robotic system for the disabled who needs supports at meal is proposed. A feature of this system is that the robotic aid system can communicate with the operator using the speech recognition and speech synthesis functions. Another feature is that the robotic aid system uses an image processing, and by doing this the system can recognize the environmental situations of the dishes, cups and so on. Due to this image processing function, the operator does not need to specify the position and the posture of the dishes and target objects. Furthermore, combination communication between speech and image processing will enables a friendly man-machine to communicate with each other, since speech and visual information are essential in the human communication.

    Important strides have been made recently in upgrading the global food aid agenda in line with evolving medical and nutrition sciences, operational experience, and innovations in food technology. A 2011 report endorsed by the United States Agency for International Development (USAID) recommended numerous improvements to products intended to support improved survival and nutrition in humanitarian programming, as well as greater rigor and transparency in the research agenda that supports innovations in this critical field. This article reviews progress since 2011 made by USAID, and other global food aid providers, in developing food aid products that are fit-for-purpose and are appropriately formulated to save lives in emergencies and to promote healthy mothers and children in nonemergency contexts. It highlights important modifications and addition made to products and identifies persisting knowledge gaps that should be prioritized in future research.

    Ruminant herbivores have been shown to learn about food properties by associating food flavours with the food's post-ingestive consequences. Previous experimentation supporting the conditioned food aversion/preference hypothesis has generally employed very simple diet learning tasks which do not effectively represent the wide range of foods selected within single bouts typical of wild, free-ranging ruminant herbivores. We tested the ability of a ruminant herbivore to associate a food with artificially administered nutrient rewards in a designed experiment where we altered the temporal pattern of encounter with the food as well as the nature (fast or slow reward) of the post-ingestive outcome. Twenty-four goats were offered branches of Sitka spruce (SS) and Norway spruce (NS) for 4 h per day on two days per week for five weeks. The pattern of feeding varied with treatment such that the species on offer changed every hour (short) or every 2 h (long). The energy treatment altered the reward delivered during Sitka consumption so that animals were dosed either with predominantly sugar (rapidly fermented), predominantly starch (slower fermentation rate), or with water (placebo). Preference was measured on the day following each learning day. We expected that goats would find it easier to associate SS with post-ingestive rewards when the duration of encounter was longest, and that associations would be stronger with the most rapidly digested post-ingestive reward. In the event, goats did not alter their consumption of SS in response to the treatments. Our results suggest that at the scale of temporal resolution of encounters with different plant species (1-2 h), and at the different rates of experiencing post-ingestive consequences tested in this experiment, ruminants do not appear to discriminate the nutritive properties of foods predominantly through a post-ingestive feedback mechanism. They must, instead, use a range of cues-including post-ingestive consequences

    An in depth understanding of the underpinning mechanisms that relate to food disruption and processing in the gastrointestinal tract is necessary to achieve optimal intake of nutrients and their bioefficacy. Although in vivo trials can provide insights on physiological responses of nutrients, in vitro assays are often applied as tools to understand specific mechanisms, or as prescreening methods to determine the factors associated with the uptake of food components in the gastrointestinal tract. In vitro assays are also often utilized to design novel or improved food delivery systems. In this review the available approaches to study delivery and uptake of food bioactives and the associated challenges are discussed. For an in depth understanding of food processing in the gastrointestinal tract, it is necessary to apply multidisciplinary methodologies, at the interface between materials science, chemistry, physics and biology.

    Droughts statistically exceed all other natural disasters in spatio-temporal extent, number of people affected or financial loss. Triggered by crop failure, food insecurity is a major manifestation of agricultural drought and water scarcity. However, other socio-economic precursors, such as chronically low levels of disaster preparedness, hampered access to food security or a lack of social safety nets are equally important factors. Consequently, this study is focused on two complementary developments - a new satellite-derived agricultural drought index and a mobile phone application. The Combined Drought Index (CDI) is enhanced by replacing field measurements of temperature and rainfall modelled/assimilated data. The vegetation component is replaced by a smoothed NDVI dataset. A soil moisture component is introduced to close the gap between rainfall deficiencies and the first visible impacts of atmospheric anomalies on vegetation. The mobile phone application enables the validation of drought index outputs and gives aid organizations an opportunity to increase the speed of socio-economic vulnerability assessments. Supported by Doctors without Borders (MSF) this approach aims at decreasing uncertainties in decision-making via a more holistic risk framework.

    Cheddar cheese was evaluated as a food carrier for the delivery of viable microorganisms of Enterococcus faecium (Fargo 688; Quest Int., Naarden, The Netherlands) to the gastrointestinal tract. This strain had previously been shown to possess properties required of a probiotic microorganism including the ability to relieve irritable bowel syndrome. The strain was found to survive to high numbers in Cheddar cheese during ripening at 8 degrees C for 15 mo (4 x 10(8) cfu/g) and in yogurt during storage at 4 degrees C for 21 d (4 x 10(7) cfu/g). In an in vitro model system, Cheddar cheese was found to have a greater protective effect than yogurt upon exposure of the probiotic culture to porcine gastric juice at pH 2. Subsequently, a feeding trial involving 8 pigs per group was performed in which a rifampicin-resistant variant of the probiotic strain was fed for 21 d at a mean daily intake of 1.3 x 10(10) cfu/d from Cheddar cheese or 3.7 x 10(9) cfu/d from yogurt. During the feeding period, Cheddar cheese yielded a significantly higher mean fecal probiotic count (2 x 10(6) cfu/g of feces) than did yogurt (5.2 x 10(5) cfu/g of feces). These data indicate that mature Cheddar cheese compares very favorably with fresh yogurt as a delivery system for viable probiotic microorganisms to the gastrointestinal tract.

  10. Hotspots of inefficiency: Mapping the difference between crop production and food calorie delivery

    Cassidy, E. S.; Foley, J. A.

    2012-12-01

    Meeting growing demands for food calories will be a substantial challenge. One place to search for solutions is in how we allocate the world's crops, and finding ways to feed more people with current crop production. Currently, a substantial proportion of crop calories are used as animal feed, and only a small fraction of those feed calories ultimately contribute to human diets. Countries like the United States and China, which together produce over a third of the world's meat, eggs and dairy, lose a substantial portion of calories and protein to the feed-to-animal conversion process. This study looks at global croplands that have a large difference between calories grown, and the food calories available for consumption. These hotspots have the potential to feed more people, while reducing environmental impacts of agriculture.;

    This paper describes a simple and sensitive kinetic spectrophotometric method for the simultaneous determination of Amaranth, Ponceau 4R, Sunset Yellow, Tartrazine and Brilliant Blue in mixtures with the aid of chemometrics. The method involved two coupled reactions, viz. the reduction of iron(III) by the analytes to iron(II) in sodium acetate/hydrochloric acid solution (pH 1.71) and the chromogenic reaction between iron(II) and hexacyanoferrate(III) ions to yield a Prussian blue peak at 760 nm. The spectral data were recorded over the 500-1000 nm wavelength range every 2s for 600 s. The kinetic data were collected at 760 nm and 600 s, and linear calibration models were satisfactorily constructed for each of the dyes with detection limits in the range of 0.04-0.50 mg L(-1). Multivariate calibration models for kinetic data were established and verified for methods such as the Iterative target transform factor analysis (ITTFA), principal component regression (PCR), partial least squares (PLS), and principal component-radial basis function-artificial neural network (PC-RBF-ANN) with and without wavelet packet transform (WPT) pre-treatment. The PC-RBF-ANN with WPT calibration performed somewhat better than others on the basis of the %RPE(T) (approximately 9) and %Recovery parameters (approximately 108), although the effect of the WPT pre-treatment was marginal (approximately 0.5% RPE(T)). The proposed method was applied for the simultaneous determination of the five colorants in foodstuff samples, and the results were comparable with those from a reference HPLC method.

    Forty-nine million individuals are food insecure in the United States, where food insecurity and HIV/AIDS are prevalent among the urban poor. Food insecurity is associated with risky sexual behaviours among people living with HIV/AIDS (PLHIV). No qualitative studies, however, have investigated the mechanisms underlying this relationship either in a resource-rich setting or among populations that include men who have sex with men (MSM). Semi-structured in-depth interviews were conducted with 34 low-income PLHIV receiving food assistance in the San Francisco Bay Area. The interviews explored experiences with food insecurity and perceived associations with sexual risk behaviours. Interviews were conducted in English, audio-recorded and transcribed verbatim. Transcripts were coded and analyzed according to content analysis methods using an inductive-deductive approach. Food insecurity was reported to be a strong contributor to risky sexual practices among MSM and female participants. Individuals described engaging in transactional sex for food or money to buy food, often during times of destitution. Participants also explained how food insecurity could lead to condomless sex despite knowledge of and desire to use safe sexual practices, largely because the need to obtain food in the short term was prioritized over the desire to use barrier protection. Our data extend previous research by demonstrating that food insecurity contributes to transactional and unprotected sex among urban poor individuals in a resource-rich setting, including among MSM. These findings underscore the importance of public health and social intervention efforts focused on structural inequalities.

    Vulnerable population groups, including people living with HIV/Aids (PLHA), may have a high prevalence of food insecurity (FI). A cross-sectional study evaluated the internal validity of the Brazilian Food Insecurity Scale (Escala Brasileira de Insegurança Alimentar - EBIA) and measured the prevalence of FI in a sample of 796 PLHA in João Pessoa, Paraíba State (PB). The validation was performed using a Rasch analysis. The association of FI with sociodemographic and clinical characteristics was assessed using the chi-square test. Associated variables were included in a Poisson multiple regression model. The EBIA was valid for PLHA with fit values within the expected limits and item severity conforming to the theoretical model. The EBIA identified 66.5% of PLHA with FI in the sample (30.8% mild FI, 18.1% moderate FI and 17.6% severe FI). Moderate FI and severe FI were associated with an age younger than 43 years (prevalence ratio (PR) = 1.49; 95% confidence interval (CI): 1.14-1.86), primary education (PR=1.64; 95% CI: 1.24-2.17), income per capita lower than ½ minimum wage (MW) (PR=1.83; 95% CI: 1.37-2.44), lack of occupation (PR=1.59; 95% CI: 1.16-2.19) and adult-only households with a female reference person (PR=2.19; 95% CI: 1.45-3.31). The PLHA in this study had a high prevalence of FI, worsening their living conditions and potentially exacerbating their health problems.

    Full Text Available ABSTRACT Background: Ability to produce breast-milk is to some extent dependent on the storage of material from the mother's food during the prenatal period, as well as on the supply of nutrients from the food she receives during lactation. Objective: To study association of maternal food consumption during pregnancy and the first time breastfeeding after delivery. Methods: We took advantage from a cross-sectional research for Development of Media and Promotional Strategies for Exclusive Breastfeeding in rural and urban West Java, 2006. The analysis is based on 609 mothers who had infants aged 6-12 months in the Bandung city and district, West Java. ‘The first time breastfeeding after delivery’ was identified from the question of ‘how many hours after birth did mother breastfeed her child for the first time’. We used Chi-Square to analyze the association between the mother’s food consumption during prenatal period and the first time breastfeeding after delivery. Results: Mothers who ate more food during pregnancy as much as 1-2 servings per day of pre-pregnancy and the occasional drink of milk to the baby was feeding time less than 3 hours after birth. Whereas mothers who during pregnancy eating just the same as before pregnancy, the first time breastfeeding was longer than 3 hours or even up to 2 days after delivery. The test results obtained was statistically significant difference. Conclusion: Maternal food consumption during pregnancy is significantly associated with the first time breastfeeding after delivery.

    Chronic delivery of neuropeptides in the brain is a useful experimental approach to study their long-term effects on various biological parameters. In this work, we tested albumin-alginate microparticles, as a potential delivery system, to study if continuous release in the hypothalamus of α-melanocyte-stimulating hormone (α-MSH), an anorexigenic neuropeptide, may result in a long-term decrease in food intake and body weight. The 2-week release of α-MSH from peptide-loaded particles was confirmed by an in vitro assay. Then, daily food intake and body weight were studied for 18 days in rats injected bilaterally into the paraventricular hypothalamic nucleus with particles loaded or not with α-MSH. A decrease in body weight gain, persisting throughout the study, was found in rats injected with α-MSH-charged particles as compared with rats receiving non-charged particles and with rats injected with the same dose of α-MSH in solution. Food intake was significantly decreased for 3 days in rats receiving α-MSH-loaded particles and it was not followed by the feeding rebound effect which appears after food restriction. The presence of α-MSH-loaded particles in the hypothalamus was confirmed by immunohistochemistry. In conclusion, our study validates albumin-alginate microparticles as a new carrier system for long-term delivery of neuropeptides in the brain and demonstrates that chronic delivery of α-MSH in the hypothalamus results in a prolonged suppression of food intake and a decrease of body weight gain in rats.

    Evidence of the impact of homestead food production programs on nutrition outcomes such as anemia and growth is scant. In the absence of information on program impact pathways, it is difficult to understand why these programs, which have been successful in increasing intake of micronutrient-rich foods, have had such limited documented impact on nutrition outcomes. To conduct a process evaluation of Helen Keller International's (HKI's) homestead food production program in Cambodia to assess whether the program was operating as planned (in terms of design, delivery, and utilization) and to identify ways in which the program might need to be strengthened in order to increase its potential for impact. A program theory framework, which laid out the primary components along the hypothesized program impact pathways, was developed in collaboration with HKI and used to design the research. Semistructured interviews and focus group discussions with program beneficiaries (n = 36 and 12, respectively), nonbeneficiaries (n = 12), and program implementers (n = 17 and 2, respectively) and observations of key program delivery points, including health and nutrition training sessions (n = 6), village model farms (n = 6), and household gardens of beneficiaries (n = 36) and nonbeneficiaries (n = 12), were conducted to assess the delivery and utilization of the primary program components along the impact pathways. The majority of program components were being delivered and utilized as planned. However, challenges with some of the key components posited to improve outcomes such as anemia and growth were noted. Among these were a gap in the expected pathway from poultry production to increased intake of eggs and poultry meat, and some weaknesses in the delivery of the health and nutrition training sessions and related improvements in knowledge among the village health volunteers and beneficiaries. Although the program has been successful in delivering the majority of the program

    Participatory and interdisciplinary approaches have been suggested to develop appropriate agricultural innovations as an alternative strategy to improve food security and well-being among HIV/AIDS affected households. However, sustainable implementation of such interactive approaches is far from easy and straight forward. This study reports of the Interactive Learning and Action (ILA) approach, a methodology for agricultural innovation which has been adapted to the context of HIV/AIDS. Role players in agriculture and health were brought together to stimulate and sustain innovation among three support groups for poor and affected households in a rural high HIV/AIDS prevalence area in South Africa. The effectiveness of the approach was evaluated using both outcome and process criteria. The results indicate that an interactive approach in which service providers/researchers engage themselves as actors to explore the livelihood system and develop appropriate solutions in joint collaboration with resource users has potential. However, it also revealed that cooperation among participants and stakeholders at the interface of agriculture and HIV/AIDS is complicated and sensitive to erosion. Of particular concern was the difficulty of mobilizing members from poor and affected households to participate and to overcome stigma and discrimination. Lessons and potential applications for the further development of interactive approaches are discussed.

  8. Why foreign aid fails

    Directory of Open Access Journals (Sweden)

    Prokopijević Miroslav

    2007-01-01

    Full Text Available The main point of this paper is that foreign aid fails because the structure of its incentives resembles that of central planning. Aid is not only ineffective, it is arguably counterproductive. Contrary to business firms that are paid by those they are supposed to serve (customers, aid agencies are paid by tax payers of developed countries and not by those they serve. This inverse structure of incentives breaks the stream of pressure that exists on the commercial market. It also creates larger loopholes in the principle-agent relationship on each point along the chain of aid delivery. Both factors enhance corruption, moral hazard and negative selection. Instead of promoting development, aid extends the life of bad institutions and those in power. Proposals to reform foreign aid – like aid privatization and aid conditionality – do not change the existing structure of the incentives in aid delivery, and their implementation may just slightly improve aid efficacy. Larger improvement is not possible. For that reason, foreign aid will continue to be a waste of resources, probably serving some objectives different to those that are usually mentioned, like recipient’s development poverty reduction and pain relief.

    As an important group of brominated flame retardants, polybrominated diphenyl ethers (PBDEs) persist in the wildlife food webs. However, the biomagnification of PBDEs has not been adequately studied in the terrestrial food webs. In this study, a terrestrial food web composed of common kestrels, sparrows, rats, grasshoppers, and dragonflies in the urban environment from northern China was obtained. A field prey delivery study, reinforced by δ¹³C and δ¹⁵N analyses, indicates that sparrows are the primary prey items of common kestrels. Concentrations of PBDEs were in the following order: common kestrel > sparrow > rat > grasshopper and dragonfly with BDE-209 as the dominant congener. Biomagnification factors (BMFs) were calculated as the ratio between the lipid normalized concentrations in the predator and prey. The highest BMF (6.9) was determined for BDE-153 in sparrow/common kestrel food chain. Other higher brominated congeners, such as BDE-202, -203, -154, -183, -197, and -209, were also biomagnified in this terrestrial food chain with BMF of 1.3-4.7. BDE-47, -99, and -100 were found to be biodiluted from sparrow to common kestrel (BMFs American kestrels from another study. Retention factors and metabolism of BDE congeners may be confounding factors influencing the measured BMFs in this current study.

    Previous literature suggests that increasing numbers of development aid donors can reduce aid effectiveness but this has not been tested in the health sector, which has experienced substantial recent growth in aid volume and number of donors. Based on annual data for 1995-2010 on 139 low- and middle-income countries that received health sector aid from donors reporting to the OECD's Creditor Reporting System, the study used two-step system generalized method of moments regression models to test whether the number of health aid donors and an index of health aid donor fragmentation affect health services (measured by DTP3 immunization rate) or health outcomes (measured by infant mortality rate) for three subsectors of health aid. For total health aid and for the general and basic health aid subsector, controlling for economic and political conditions, increases in the number of donors were associated with increases in DTP3 immunization rate and reductions in infant mortality while increases in the donor fragmentation index were associated with decreases in DTP3 immunization rate and increases in infant mortality, though none of these relationships were statistically significant. For the population and reproductive health aid subsector, a one percent increase in the number of donors was associated with a 0.23 percent decrease in DTP3 immunization ( P <  0.01) while a one percent increase in donor fragmentation was associated with a 0.54 percent increase in DTP3 immunization rate ( P <  0.01); associations with infant mortality rates for this subsector were similar to those for total health aid. The results do not provide clear evidence in support of the hypothesis that donor proliferation negatively impacts development results in the health sector. Aid effectiveness policy prescriptions should distinguish responses to donor proliferation versus donor fragmentation and be adapted to specific subsectors of health aid. © The Author 2016.

    There is one commodity the world over that unites mankind-food. In 2011 the United Nations claimed that the world's population had reached the seven billion mark, a number which is set to increase dramatically in the decades to come. Food security, supply and sustainability are of paramount concern to the future economic and social progress of humanity. It is the responsibility of the food industry, together with food scientists and technologists, to shoulder the burden of ensuring an adequate supply of nutritious, safe and sensorially acceptable foods for a range of demanding consumers. In responding to this challenge, we need to understand the link between agriculture, engineering, food processing, molecular biosciences, human nutrition, commercialisation and innovation. Access to information concerning the composition and quality of foods has never been so easy for consumers and technologists alike. A plethora of research publications are made available each month to scientists and associated interested parties. The outcomes of these research manuscripts are often distilled and disseminated into messages available to everyone through bulletin boards, forums and the popular press. Newspapers and new agencies constantly report on the latest pharma-medical finding, or news regarding food safety and security concerns. We live in an age where information is so readily available to everyone that the task of finding credible and reputable data can be difficult at times. Providing sound evidenced based research is where a peer-reviewed journal can provide clarity. [...].

    2011-09-01

    Full Text Available The countries Kenya, Uganda, Somalia, Ethiopia and Djibouti are facing the worst food crisis of the 21st century as a result of devastating droughts. The crisis is causing starvation and leading to a lack of access to clean water and sanitation for over 12 million people. Not only are the direct drought effects endured now by the population, but they have weakened response capacity and created diminished prospects of ever achieving future water and food security. Over the coming decades, temperatures in this region will continue to rise and rainfall patterns will change. This will create major problems for food production and availability. Thus, building resilience in communities is indispensable as we adapt our farming systems to the challenges of climate change. This will require practical solutions that can build on processes involving adaptation to climate change. The lessons learned from the UN-led project in Uganda, demonstrate the value of small scale innovative interventions, carried out using democratic approaches to help support adaptation to climate change whilst progressing to achieve food security and chart a new Path to eliminate hunger. These lessons should be our guiding vision as we address the current droughts plaguing the Horn of East Africa and elsewhere.

  15. Quality-by-design based development of a self-microemulsifying drug delivery system to reduce the effect of food on Nelfinavir mesylate.

    Poor aqueous solubility and moderate permeability of Nelfinavir mesylate (NFM) leads to high variability in absorption after oral administration. To improve the solubility and bioavailability of NFM, the self microemulsifying drug delivery system (SMEDDS) was developed. For this purpose, Quality by design (QbD) approach employing D-optimal mixture design was used to prepare SMEDDS of NFM. Further, the software generated numerically optimized SMEDDS were developed by utilizing desirability function. Maisine 35-1, Tween 80, and Transcutol HP were identified as oil, surfactant, and co-surfactant that had best solubility for NFM. Ternary phase diagrams were plotted to identify the self-emulsification region. Dissolution of putative NFM in simulated fasted or fed small intestinal conditions, respectively, predicted that there is a positive food effect. However, NFM loaded SMEDDS showed absence of food effect with no significant difference in dissolution performance either in Fasted or fed state simulated intestinal fluid (FaSSIF or FeSSIF) biorelevent dissolution media. The prepared SMEDDS were thermodynamically stable with droplet size (121 nm), poly dispersity index (PDI) (0.198) and emulsification time (food effect on pure NFM suspension. However, absence of food effect and 3.5-3.6 fold enhancement in the oral bioavailability was observed when NFM was formulated into SMEDDS. Thus, it could be envisaged that development of SMEDDS formulation of NFM could be one of the best alternative to enhance oral bioavailability of NFM. Copyright © 2016 Elsevier B.V.

    Positive food effects may be observed for low aqueous soluble compounds, these effects could potentially be circumvented using lipid based formulations. However, as all compounds are not chemically stable in lipid based systems, alternative dosage regimes could be investigated to evade the stability issue. The two aims for this present study were therefore; i) to investigate if a nutritional drink, Fresubin Energy®, could induce food effect in humans for the poorly soluble compound cinnarizine; and ii) to investigate if co-administration of a self-nano-emulsifying drug delivery systems (SNEDDS) with a conventional cinnarizine tablet could reduce the observed food-effect. A commercial conventional cinnarizine tablet was dosed to 10 healthy volunteers in a cross-over design in both fasted and fed state, with and without co-administration of a SNEDDS, with a one week wash-out period between dosing. The fed state was induced using a nutritional drink (Fresubin Energy®) and gastric emptying was assessed by administration of paracetamol as a marker. The pharmacokinetic analysis showed that the nutritional drink delayed the uptake and increased the fraction of absorbed cinnarizine, indicative of a food effect on the compound. This was in agreement with a previous dog study and indicates that the nutritional drink can be used for inducing the same level of food effect in humans. Though not statistically significant, the co-administration of SNEDDS exhibited a tendency towards a reduction of the observed food effect and an increased absorption of cinnarizine in the fasted state; based upon the individual ratios, which was not reflected in the mean data. However, the co-administration of SNEEDS in the fasted state, also induce a slower gastric emptying rate, which was observed as a delayed tmax for both cinnarizine and paracetamol.

    HIV-related stigma among persons living with HIV/AIDS (PLHIV) is prevalent throughout sub-Saharan Africa. There is limited evidence, however, on which interventions are effective in reducing it. We used data from a prospective impact evaluation of a 12-month food assistance intervention among 904 antiretroviral therapy (ART)- naïve PLHIV in Uganda to examine the program impact on stigma. Stigma was measured using the comprehensive HASI-P scale, which demonstrated good internal consistency (Cronbach's alpha = 0.87) and was correlated with several related constructs including physical and mental health-related quality of life, disclosure, and physical health symptoms in the sample. Using quasi-experimental difference-in-difference matching methods to better infer causality, we tested whether the intervention improved the overall stigma scale and its subscales. The food assistance intervention had a significant effect on reported internalized (but not external) stigma of approximately 0.2 SD (p stigma scale is a useful tool for measuring and tracking stigma. Food assistance interventions, embedded in an HIV care program, can reduce internalized stigma.

  19. The Work of Hunger: Security, Development and Food-for-Work in Post-crisis Jakarta

    Directory of Open Access Journals (Sweden)

    Jamey Essex

    2009-10-01

    Full Text Available Food-for-work programs distribute food aid to recipients in exchange for labor, and are an important mode of aid delivery for both public and private aid providers. While debate continues as to whether food-for-work programs are socially just and economically sensible, governments, international institutions, and NGOs continue to tout them as a flexible and cost-effective way to deliver targeted aid and promote community development. This paper critiques the underlying logic of food-for-work, focusing on how this approach to food aid and food security promote labor force participation by leveraging hunger against poverty, and how the ideological and practical assumptions of food-for-work become enmeshed within discourses of geopolitical security. I rely on a case study examination of US-funded food-for-work programs implemented in Jakarta, Indonesia following the 1997 financial crisis. The crisis produced acute food insecurity and poverty in Indonesia, provoking fears of mob violence by the hungry poor and the spread of radical Islamism in the post-crisis political vacuum. Food-for-work programs were, in this context, meant to resolve the problems of both food insecurity and geopolitical insecurity by providing food to targeted populations, employment to those otherwise thrown out of work, and resituating the hungry poor in relation to broader scales of local, national, and global power.

    The study was aimed at systematically investigating the influence of shell composition on the particle size, stability, release, cell uptake, permeability, and in vivo gastrointestinal distribution of food protein based nanocarriers for oral delivery applications. Three different core-shell nanocarriers were prepared using food-grade biopolymers including zein-casein (ZC) nanoparticles, zein-lactoferrin (ZLF), nanoparticles and zein-PEG (ZPEG) micelles. Nile red was used as a model hydrophobic dye for in vitro studies. The nanocarriers had negative, positive, and neutral charge, respectively. All three nanocarriers had a particle size of less than 200 nm and a low polydispersity index. The nanoparticles were stable at gastrointestinal pH (2-9) and ionic strength (10-200 mM). The nanocarriers sustained the release of Nile red in simulated gastric and intestinal fluids. ZC nanoparticles showed the slowest release followed by ZLF nanoparticles and ZPEG micelles. The nanocarriers were taken up by endocytosis in Caco-2 cells. ZPEG micelles showed the highest cell uptake and transepithelial permeability followed by ZLF and ZC nanoparticles. ZPEG micelles also showed P-gp inhibitory activity. All three nanocarriers showed bioadhesive properties. Cy 5.5, a near IR dye, was used to study the in vivo biodistribution of the nanocarriers. The nanocarriers showed longer retention in the rat gastrointestinal tract compared to the free dye. Among the three formulations, ZC nanoparticles was retained the longest in the rat gastrointestinal tract (≥24 h). Overall, the outcomes from this study demonstrate the structure-function relationship of core-shell protein nanocarriers. The findings from this study can be used to develop food protein based oral drug delivery systems with specific functional attributes.

    This study aimed to assess the role of gender on HIV/AIDS stigma among 507 medical students in Puerto Rico. A secondary data analysis was performed with baseline measurements of a controlled randomized study. Unadjusted analyses showed that the overall multivariate test for gender was significant [X2(11) = 38.79, p = .0001]. Males evidenced higher stigma levels on multiple dimensions of HIV/AIDS stigma. Findings suggest that gender needs to be taken into consideration when engaging in stigma research and when developing stigma reduction interventions as part of medical students training.

    Walker, Rebecca; Decker, Eric A; McClements, David Julian

    2015-01-01

    Consumption of biologically active amounts of omega-3 fatty acids is linked to improved human health, which has partly been attributed to their important role in brain development and cardiovascular health. Western diets are relatively low in omega-3 fatty acids and many consumers turn to supplements or functional foods to increase their intake of these healthy lipids. Fish oil is one of the most widely used sources of omega-3 fatty acid for supplementation and has greater health benefits than plant sources because of its higher concentration of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). The incorporation of omega-3 fatty acids into foods and beverages is often challenging due to their low water-solubility, poor oxidative stability, and variable bioavailability. Nanoemulsions offer a promising way to incorporate omega-3 fatty acids into liquid food systems like beverages, dressing, sauces, and dips. Nanoemulsions are colloidal dispersions that contain small oil droplets (rfoods and beverages with omega-3 fatty acids. The composition and fabrication of nanoemulsions can be optimized to increase the chemical and physical stability of oil droplets, as well as to increase the bioavailability of omega-3 fatty acids.

    The supplementation program of the community nutrition project (PNC) launched by the Senegalese Government in order to protect the most vulnerable groups (children and women) was evaluated. Using a stable isotope (deuterium), we assessed the effect of the PNC on breastmilk output, mother's body composition, and baby's growth at three months of lactation. Breastmilk triglycerides, lactose, protein, and zinc were also determined. Mothers who were supplemented more than 60 days during pregnancy showed a significant increase in fat-free mass as compared to those who were supplemented for less than 30 days (p = .03). Breastmilk output was not influenced by the supplementation, but breastmilk lactose, total protein, and zinc contents increased significantly (p supplemented mothers. Growth of the babies of the supplemented mothers was better than that of those whose mothers were not supplemented. It was concluded that the food supplementation had beneficial effects on both mothers' and babies' nutritional status depending on the onset of the supplementation.

    Full Text Available Highly Active Antiretroviral therapy (HAART promotes anthropometric changes in lipid metabolism and glucose in patients with Human Immunodeficiency Virus (HIV. Functional foods play an important role on metabolism. Bioactive Food Compound (BFC has shown effective results in changes arising from decompensated lipid metabolism due to the effects of HAART on HIV patients. From this perspective, the objective of this study is to evaluate anthropometric indicators and the body composition of patients undergoing HAART before and after consumption of BFC.This is a prospective intervention with 180 individuals with HIV undergoing HAART. They formed two groups and were monitored for 3 months: the first group consisted of individuals who consumed BFC (n = 121 at the recommended daily intake of 40 g. The second group consisted of individuals who did not consume BFC (n = 59. We determined body mass index (BMI, waist circumference (WC, waist-hip ratio (WHR, conicity index (CI and antiretroviral regimen used by the patients.The BMI among adults (p<0.001, the WC (p<0.001 and p<0.014 for men and women, respectively and the CI (p = 0.001 and p<0.001 for men and women, respectively increased at the end of the study in the group of individuals who did not consume BFC and remained stable in the BFC group. There were no changes in WHR in any of the groups evaluated. Regarding the antiretroviral regimens used, we observed that there was no difference between regimens as for BMI, WC, WHR and CI.The BFC consumed by HIV patients undergoing HAART allowed the maintenance of anthropometric measures without increasing the mean values of conicity index, suggesting that the consumption of this bioactive compound protects the individual against the development of metabolic syndrome (MeS in patients infected with HIV undergoing antiretroviral therapy.

    Hendricks, Michael K; Eley, Brian; Bourne, Lesley T

    2007-10-01

    The implications for food-based dietary guidelines (FBDGs) that are being developed in South Africa are reviewed in relation to HIV-exposed and -infected children. The nutritional consequences of HIV infection and nutritional requirements along with programmes and guidelines to address undernutrition and micronutrient deficiency in these children are also investigated. Based on studies for HIV-infected children in South Africa, more than 50% are underweight and stunted, while more than 60% have multiple micronutrient deficiencies. Nutritional problems in these children are currently addressed through the Prevention-of-Mother-to-Child Transmission Programme (PMTCT), the Integrated Nutrition Programme and Guidelines for the Management of HIV-infected Children which include antiretroviral (ARV) therapy in South Africa. Evaluations relating to the implementation of these programmes and guidelines have not been conducted nationally, although certain studies show that coverage of the PMTCT and the ARV therapy programmes was low. FBDGs for infants and young children could complement and strengthen the implementation of these programmes and guidelines. However, FBDGs must be in line with national and international guidelines and address key nutritional issues in these infants and young children. These issues and various recommendations are discussed in detail in this review.

  14. Implementing AIDS Education

    Full Text Available The world has been challenged by the AIDS epidemic for 15 years. In 1985, the U.S. Department of Health and Human Services, Centers for Disease Control, allocated funds to all state departments of education to assist schools in the development of AIDS education policies and programs. Yet, these policies do not ensure that all students receive effective AIDS education. On September 21, 1991, the Arizona Legislature passed Senate Bill 1396, which requires public schools to annually provide AIDS education in grades K-12. The bill was rescinded in 1995. With prohibitive curriculum guidelines, limited teacher training opportunities and tremendous instructional demands, this educational policy was implemented in disparate forms. By examining the perspectives of the Arizona educators (representing three school districts, this qualitative study reveals how teachers ultimately controlled the delivery and nature of AIDS instruction based upon personal values, views of teacher roles, and their interpretation of the mandate itself.

    The enormous magnitude and variety of microwave applications in household, commercial and industrial food processing creates a strong motivation for improving the energy efficiency and hence, sustainability of the process. This review critically assesses key energy issues associated with microwave food processing, focusing on previous energy performance studies, energy performance metrics, standards and regulations. Factors affecting energy-efficiency are categorised into source, load and source-load matching factors. This highlights the need for highly-flexible and controllable power sources capable of receiving real-time feedback on load properties, and effecting rapid control actions to minimise reflections, heating non-uniformities and other imperfections that lead to energy losses. A case is made for the use of solid-state amplifiers as alternatives to conventional power sources, magnetrons. By a full-scale techno-economic analysis, including energy aspects, it is shown that the use of solid-state amplifiers as replacements to magnetrons is promising, not only from an energy and overall technical perspective, but also in terms of economics.

    Despite progress with the food-associated health agenda in the public health and clinical domains, much remains to be done in Indonesia. There are reasons to be optimistic which include economic development, increasing literacy, progress towards universal health coverage and community organizational arrangements across the archipelago which focus on health through some 10,000 puskesmas. These community health centres are variably staffed with voluntary cadres from the community, bidans (nurses) and general medical practitioners. For more effective prevention and management of nutritionally-related health problems, innovative community and clinical nutrition research and expertise is required. With rapid urbanisation, the growth of the digital economy, increasing socio-economic inequity and climate change, there are imperatives for ecologically sustainable, nonemployment dependent livelihoods which provide energy, food, water, education and health care security. A relevant health care workforce will include those who research and practice clinical nutrition. Here we gather together an account of an extensive body of published and emerging literature which makes a case collectively for a more ecological approach to nutrition and health and how it might revitalise the Indonesian and other health care systems.

    DREAM (Drug Resources Enhancement against AIDS and Malnutrition) is a multiregional health program active in Mozambique since 2002 and provides free of charge an integrating package of care consisting of peer to peer nutritional and health education, food supplementation, voluntary counseling and testing, immunological, virological, clinical assessment and HAART (Highly Active AntiRetroviral Treatment). The main goals of this paper are to describe the state of health and nutrition and the adequacy of the diet of a sample of HIV/AIDS patients in Mozambique on HAART and not. A single-arm retrospective cohort study was conducted. 106 HIV/AIDS adult patients (84 in HAART), all receiving food supplementation and peer-to-peer nutritional education, were randomly recruited in Mozambique in two public health centres where DREAM is running. The programme is characterized by: provision of HAART, clinical and laboratory monitoring, peer to peer health and nutritional education and food supplementation. We measured BMI, haemoglobin, viral load, CD4 count at baseline (T0) and after at least 1 year (T1). Dietary intake was estimated using 24h food recall and dietary diversity was assessed by using the Dietary Diversity Score (DDS) at T1. Overall, the patients'diet appeared to be quite balanced in nutrients. In the cohort not in HAART the mean BMI values showed an increases but not significant (initial value: 21.9 ± 2.9; final value: 22.5 ± 3.3 ) and the mean haemoglobin values (g/dl) showed a significant increases (initial value: 10.5+ 2.1; final value: 11.5 ± 1.7 pnutritional status improvement was observed in both cohorts. The improvement in BMI was significant and substantially higher in HAART patients because of the impact of HAART on nutritional status of AIDS patients. Subjects on HAART and with a DDS > 5, showed a substantial BMI gain. This association showed an additional expression of the synergic effect of integrating food supplementation, nutritional education and

    2010-06-01

    Full Text Available Abstract Background The evidence evaluating the benefits of programmatic nutrition interventions to HIV-infected individuals in developing countries, where there is a large overlap between HIV prevalence and malnutrition, is limited. This study evaluates the impact of food assistance (FA on change in weight and disease progression as measured by WHO staging. Methods We utilize program data from The AIDS Support Organization (TASO in Uganda to compare outcomes among FA recipients to a control group, using propensity score matching (PSM methods among 14,481 HIV-infected TASO clients. Results FA resulted in a significant mean weight gain of 0.36 kg over one year period. This impact was conditional on anti-retroviral therapy (ART receipt and disease stage at baseline. FA resulted in mean weight gain of 0.36 kg among individuals not receiving ART compared to their matched controls. HIV-infected individuals receiving FA with baseline WHO stage II and III had a significant weight gain (0.26 kg and 0.2 kg respectively compared to their matched controls. Individuals with the most advanced disease at baseline (WHO stage IV had the highest weight gain of 1.9 kg. The impact on disease progression was minimal. Individuals receiving FA were 2 percentage points less likely to progress by one or more WHO stage compared to their matched controls. There were no significant impacts on either outcome among individuals receiving ART. Conclusions Given the widespread overlap of HIV and malnutrition in sub-Saharan Africa, FA programs have the potential to improve weight and delay disease progression, especially among HIV-infected individuals not yet on ART. Additional well designed prospective studies evaluating the impact of FA are urgently needed.

  4. Multiple stressors in Southern Africa: the link between HIV/AIDS, food insecurity, poverty and children's vulnerability now and in the future.

    2009-01-01

    Several countries in Southern Africa now see large numbers of their population barely subsisting at poverty levels in years without shocks, and highly vulnerable to the vagaries of the weather, the economy and government policy. The combination of HIV/AIDS, food insecurity and a weakened capacity for governments to deliver basic social services has led to the region experiencing an acute phase of a long-term emergency. "Vulnerability" is a term commonly used by scientists and practitioners to describe these deteriorating conditions. There is particular concern about the "vulnerability" of children in this context and implications for children's future security. Through a review of literature and recent case studies, and using a widely accepted conceptualisation of vulnerability as a lens, we reflect on what the regional livelihoods crisis could mean for children's future wellbeing. We argue that an increase in factors determining the vulnerability of households - both through greater intensity and frequency of shocks and stresses ("external" vulnerability) and undermined resilience or ability to cope ("internal" vulnerability) - are threatening not only current welfare of children, but also their longer-term security. The two specific pathways we explore are (1) erosive coping strategies employed by families and individuals; and (2) their inability to plan for the future. We conclude that understanding and responding to this crisis requires looking at the complexity of these multiple stressors, to try to comprehend their interconnections and causal links. Policy and programme responses have, to date, largely failed to take into account the complex and multi-dimensional nature of this crisis. There is a misfit between the problem and the institutional response, as responses from national and international players have remained relatively static. Decisive, well-informed and holistic interventions are needed to break the potential negative cycle that threatens the

    To assess the accuracy of portion-size estimates and participant preferences using various presentations of digital images. Two observational feeding studies were conducted. In both, each participant selected and consumed foods for breakfast and lunch, buffet style, serving themselves portions of nine foods representing five forms (eg, amorphous, pieces). Serving containers were weighed unobtrusively before and after selection as was plate waste. The next day, participants used a computer software program to select photographs representing portion sizes of foods consumed the previous day. Preference information was also collected. In Study 1 (n=29), participants were presented with four different types of images (aerial photographs, angled photographs, images of mounds, and household measures) and two types of screen presentations (simultaneous images vs an empty plate that filled with images of food portions when clicked). In Study 2 (n=20), images were presented in two ways that varied by size (large vs small) and number (4 vs 8). Convenience sample of volunteers of varying background in an office setting. Repeated-measures analysis of variance of absolute differences between actual and reported portions sizes by presentation methods. Accuracy results were largely not statistically significant, indicating that no one image type was most accurate. Accuracy results indicated the use of eight vs four images was more accurate. Strong participant preferences supported presenting simultaneous vs sequential images. These findings support the use of aerial photographs in the automated self-administered 24-hour recall. For some food forms, images of mounds or household measures are as accurate as images of food and, therefore, are a cost-effective alternative to photographs of foods.

    Sugiura, Jun; Nakajima, Masahiro

    2017-05-01

    A simple HPLC method was developed for the simultaneous analysis of nine preservatives in food including benzoic acid, sorbic acid, dehydroacetic acid, methyl paraben, ethyl paraben, isopropyl paraben, propyl paraben, isobutyl paraben and butyl paraben. Samples were extracted with 60 v/v% methanol containing poly-aluminium chloride (PAC) and sodium hydroxide prior to analysis. PAC, which is normally used as a coagulant, was successfully applied to remove interfering substances from the samples. The method showed good linearity with coefficients of determination higher than 0.999 over the range of 0.2-5 µg ml -1 for all target preservatives. LOQs of the method were in the range of 0.002-0.008 g kg -1 . Method performance was evaluated in a variety of foods demonstrated to have quantitative recoveries of 81.7-102.5% with satisfactory intra-day precision of foods containing preservatives.

    1987-01-01

    An expert system called the ATHENA AIDE that assists in the preparation of input models for the ATHENA thermal-hydraulics code has been developed by researchers at the Idaho National Engineering Laboratory. The ATHENA AIDE uses a menu driven graphics interface and rule-based and object-oriented programming techniques to assist users of the ATHENA code in performing the tasks involved in preparing the card image input files required to run ATHENA calculations. The ATENA AIDE was developed and currently runs on single-user Xerox artificial intelligence workstations. Experience has shown that the intelligent modeling environment provided by the ATHENA AIDE expert system helps ease the modeling task by relieving the analyst of many mundane, repetitive, and error prone procedures involved in the construction of an input model. This reduces errors in the resulting models, helps promote standardized modeling practices, and allows models to be constructed more quickly than was previously possible

The LP constraints were based on current UN recommendations for the macronutrient content of therapeutic food and included palatability, texture, and maximum food ingredient weight criteria. Nonlinear constraints for nutrient ratios were converted to linear equations to allow their use in LP. The formulation was considered accurate if laboratory results confirmed an energy density difference commodities that are cheaper, regionally available, and meet local cultural preferences. However, as with all prototype feeding products for medical use, composition analysis, safety, acceptability, and clinical effectiveness trials must be conducted to validate the formulation.

    Capps, Oral; Park, John L

    2003-07-01

    The food retailing and food service sector is not only an important component of the food marketing channel but is also vital to the United States economy, accounting for more than 7% of the United States gross domestic product in 2001. The business of food retailing and food service is undergoing salient change. The authors argue that the singular force driving this change is the consumer. To understand the linkages in the food marketing channel, this article provides information on the farm-to-retail price spread and the economic forces that influence their magnitude. Examples are given of farm-to-retail price spreads for red meat and dairy industries. In addition, the economics behind the provision of retail services and the growth of the food service industry are discussed. Further, the authors demonstrate that the structure of the food market channel is consumer driven, and present three characteristics of convenience (preparation, delivery, and service) and identify four food distribution channels in terms of convenience (complete convenience, traditional food service, consumer direct, and traditional retail).

    We studied the impact of a food supplementation program (Plan Más Vida (PMV)) on the micronutrient nutritional condition of pregnant women from low-income families 1 year after its implementation. The food program provided supplementary diet (wheat and maize--fortified flour, rice or sugar, and fortified soup). We performed a prospective, nonexperimental, cross-sectional study in the province of Buenos Aires, Argentina, evaluating pregnant women at baseline (n = 164) and 1 year after PMV implementation (n = 108). Biochemical tests (hemogram, ferritin, vitamin A, zinc, and folic acid), anthropometric assessments (weight and height), and dietary surveys (24 h recall) were performed at the two study points. One year after PMV implementation, no significant changes in anthropometric values were observed. Folic acid deficiency and the risk of vitamin A deficiency (retinol, 20-30 μg/dl) decreased significantly (35.8 to 6.1 % and 64 to 41 %, respectively; p good and intra-family dilution and distribution of food was high.

  19. Nanodelivery of bioactive components for food applications: types of delivery systems, properties, and their effect on ADME profiles and toxicity of nanoparticles.

    Science.gov (United States)

    Borel, T; Sabliov, C M

    2014-01-01

    Food bioactives are known to prevent aging, cancer, and other diseases for an overall improved health of the consumer. Nanodelivery provides a means to control stability, solubility, and bioavailability, and also provides controlled release of food bioactives. There are two main types of nanodelivery systems, liquid and solid. Liquid nanodelivery systems include nanoemulsions, nanoliposomes, and nanopolymersomes. Solid nanodelivery systems include nanocrystals, lipid nanoparticles, and polymeric nanoparticles. Each type of nanodelivery system offers distinct benefits depending on the compatibility of nanoparticle properties with the properties of the bioactive and the desired application. Physicochemical properties of nanoparticles such as size, charge, hydrophobicity, and targeting molecules affect the absorption, distribution, metabolism, and excretion (ADME) of nanodelivery systems. The fate of the bioactive depends on its physicochemical properties and the location of its release. The safety of nanodelivery systems for use in food applications is largely unknown. Toxicological studies consisting of a combination of in silico, in vitro, and in vivo studies are needed to reveal the safety of nanodelivery systems for successful applications in food and agriculture.

    To elucidate if a SNEDDS approach can eliminate the food-effect on cinnarizine absorption and to, investigate if a nutritional drink, Fresubin energy, could mimic food effect in dogs for the poorly soluble compound cinnarizine. A conventional tablet, a SNEDDS capsule or a SNEDDS tablet, containing cinnarizine, were dosed to beagles dogs in fed or fasted state (n=5), with a one week wash-out period between dosing. Dogs were pre-treated with pentagastrin. Fed state was induced by a nutritional drink (Fresubin Energy®). The food-effect was evaluated by comparing Tmax, Cmax and Bioavailability (F) for the different formulations. Food effect was observed on all three parameters for the conventional tablet; Tmax was delayed 2.5times and bioavailability increased in fed state (from 20.9±5.7 to 53.8±30.1). Apart from an extended Tmax (2.5 and 3.3 times longer in fed state compared to fasted state for the SNEDDS tablets and SNEDDS capsules respectively), food effect on absorption for the SNEDDS capsules and SNEDDS tablets was not observed. The SNEDDS capsules had a higher bioavailability in both fed and fasted state compared to SNEDDS tablets (Ffasted=58.1±16.7, vs. 32.7±11.5), (Ffed=79.3±14.7 vs. 43.7±6.7) There were no significant differences in bioavailability between the conventional tablet in fed state and the SNEDDS capsules. Food effect was observed when dosing cinnarizine with ingestion of the nutritional drink Fresubin Energy. Food effect on cinnarizine could be significantly reduced by dosing either as a SNEEDS capsule or a SNEDDS tablet, however, the SNEDDS tablet resulted in an overall lower absorption than the SNEDDS capsules in both fed and fasted state. The delay in fed state absorption could not be changed by dosing with SNEDDS formulations. Copyright © 2014 Elsevier B.V. All rights reserved.

    The aim of the present study was to develop chitosan-zinc-pectinate-polyethylene glycol (PEG) nanoparticles (NPs) for colon-targeted delivery of resveratrol. The effects of pectin:ZnCl 2 :chitosan (PZnC) % w/v, pH and ionic strength of media, and addition of PEG on the colloidal stability and release behavior of resveratrol from NPs were examined by Zeta potential, particle size analyzer, scanning electron microscopy (SEM), and Fourier transform-infrared (FTIR) methods. The particle size and Zeta potential of PZnC NPs in the ratio of 10:1:3% w/v were 399±18nm and +25±1mV, respectively. The addition of PEG to PZnC as a solvent for resveratrol (10% w/v) noticeably decreased the size of NPs to approximately 83±4nm. More than 63% of the resveratrol was encapsulated into the developed NPs; furthermore, a low amount of resveratrol was released during one month, using simulated juice model (pH=4) as investigated by High Performance Liquid Chromatography (HPLC) analysis of resveratrol.The remaining resveratrol in NPs (∼49%) was released in simulated colon fluid in the presence of pectinase. These NPs can be introduced as a novel platform for successful colon delivery of resveratrol in fruit juice matrix. Copyright © 2017 Elsevier B.V. All rights reserved.

    2015-01-01

    Full Text Available Multiple models of human neuropsychiatric pathologies have been generated during the last decades which frequently use chronic dosing. Unfortunately, some drug administration methods may result in undesirable effects creating analysis confounds hampering model validity and preclinical assay outcomes. Here, automated analysis of floating behaviour, a sign of a depressive-like state, revealed that mice, subjected to a three-week intraperitoneal injection regimen, had increased floating. In order to probe an alternative dosing design that would preclude this effect, we studied the efficacy of a low dose of the antidepressant imipramine (7 mg/kg/day delivered via food pellets. Antidepressant action for this treatment was found while no other behavioural effects were observed. We further investigated the potential efficacy of chronic dosing via food pellets by testing the antidepressant activity of new drug candidates, celecoxib (30 mg/kg/day and dicholine succinate (50 mg/kg/day, against standard antidepressants, imipramine (7 mg/kg/day and citalopram (15 mg/kg/day, utilizing the forced swim and tail suspension tests. Antidepressant effects of these compounds were found in both assays. Thus, chronic dosing via food pellets is efficacious in small rodents, even with a low drug dose design, and can prevail against potential confounds in translational research within depression models applicable to adverse chronic invasive pharmacotherapies.

    Full text: Food insecurity in Guinea-Bissau is widespread and micronutrient deficiencies are anticipated among vulnerable groups. The objective: to test the efficacy of two Micronutrient-Rich Ready to Use Supplementary Foods (MNR-RUSF) in rural village children aged 6 to 24 months. This study was funded by the United States Department of Agriculture as part of a larger pilot project testing different supplements in pregnant and lactating women and infants and children aged 6-59 months. 411 children were randomly assigned to one of two intervention arms (46 g MNR-RUSF sachets containing 250 kcal/sachet and either 15% or 33% of dairy protein, collected 5 days per week from a supplement distribution center in the village) or to a control (C) group that received no MNR-RUSF. Weight, height and mid upper arm circumference (MUAC), hemoglobin, and retinol-binding protein were measured at baseline and end-line. Randomization to the 33% supplement group was associated with significantly increased visits to the distribution center to collect supplement, as well as higher ratings for product taste and overall acceptability. The 15% supplement improved hemoglobin levels relative to controls (+0.81±1.43 vs. 0.07±1.47, P<0.05) and the combined 15% and 33% supplements improved hemoglobin levels relative to controls (+0.76±1.44 vs. 0.07±1.47, P<0.05). There was no difference in changes in RBP between control and supplement groups, but both 15% and 33% groups had significantly reduced rates of reported malaria, diarrhea and other illnesses compared to control infants (P<0.001). The supplements did not improve weight or length gains in the population of infants as whole, but did result in significantly greater gain in weight-for-age z score among the infants who had a z-score >-2.0 at baseline. This study is the first to examine the effects of supplements containing different amounts of dairy protein in infants and young children in Guinea-Bissau and indicates that, while

The objective: to test the efficacy of two Micronutrient-Rich Ready to Use Supplementary Foods (MNR-RUSF) in preschool children aged 3-5 years over 3 months. 9 preschools were randomly assigned to one of two intervention arms (92 gram MNR-RUSF sachets containing 500 kcal/sachet and either 15% or 33% of dairy protein, provided 5 days per week) or to a control (C) group that received no MNR-RUSF. Weight, height and mid upper arm circumference (MUAC) were measured at baseline and endline. Malnutrition at baseline was high, with 5.6% <2 z scores for weight and 7.1% <2 z scores for height. Both intervention arms showed a significant increase in weight vs. controls (ΔWeight 15% group = 0.77+0.75 kg, 33% group = 0.76+0.78 kg, C = 0.42+0.1.8 kg, p<0.05) but not in height (ΔHeight 15% group = 3.1+2.0 cm, 33% group = 2.8+2.1 cm, C = 2.8+3.8 cm, p = 0.34). Changes in weight and height were not significantly different between the 15% and 33% groups (p = 0.99 and p = 0.38, respectively). There was a significant increase in MUAC in both the intervention arms vs. control, with the 33% intervention arm demonstrating a significantly greater increase than the 15% intervention arm (ΔMUAC 15% group = -.03±0.68 cm, 33% group = 0.14±0.78 cm, C = -0.31±0.67cm, p<0.001). This study is the first to focus on anthropometry in preschool-aged children in Guinea-Bissau and indicates that while both standard and high-dairy containing MNR-RUSF products improve weight in preschool populations with a high prevalence of malnutrition, those containing high levels of dairy protein have additional benefits for improving MUAC.

    Investigation of foodborne diseases requires the capture and analysis of time-sensitive information on microbial pathogens that is derived from multiple analytical methods and sources. The web-based Pathogen-annotated Tracking Resource Network (PATRN) system (www.patrn.net) was developed to address the data aggregation, analysis, and communication needs important to the global food safety community for the investigation of foodborne disease. PATRN incorporates a standard vocabulary for describing isolate metadata and provides a representational schema for a prototypic data exchange standard using a novel data loading wizard for aggregation of assay and attribution information. PATRN currently houses expert-curated, high-quality "foundational datasets" consisting of published experimental results from conventional assays and next generation analysis platforms for isolates of Escherichia coli, Listeria monocytogenes, and Salmonella, Shigella, Vibrio and Cronobacter species. A suite of computational tools for data mining, clustering, and graphical representation is available. Within PATRN, the public curated data repository is complemented by a secure private workspace for user-driven analyses, and for sharing data among collaborators. To demonstrate the data curation, loading wizard features, and analytical capabilities of PATRN, three use-case scenarios are presented. Use-case scenario one is a comparison of the distribution and prevalence of plasmid-encoded virulence factor genes among 249 Cronobacter strains with similar attributes to that of nine Cronobacter isolates from recent cases obtained between March and October, 2010-2011. To highlight PATRN's data management and trend finding tools, analysis of datasets, stored in PATRN as part of an ongoing surveillance project to identify the predominant molecular serogroups among Cronobacter sakazakii isolates observed in the USA is shown. Use-case scenario two demonstrates the secure workspace available for private

    Nanostructured lipid carriers (NLCs) and chitosan-coated NLCs (CH-NLCs) were prepared by a combined double emulsion and melt dispersion method. The physicochemical properties of them were investigated to determine the optimum conditions. At 3% emulsifier concentration, the NLCs showed about 191.0 ± 4.1 nm mean particle size and low polydispersity index value compared to those observed under other conditions. The encapsulation efficiency of CH-NLCs was 83.9% which was about 10% higher than that of NLCs. In vitro release test showed that low release amount of iron from the NLCs (11%) and CH-NLCs (5%) in simulated gastric condition within 3 h, whereas the iron release amounts of the NLCs and CH-NLCs were high (over 77%) in simulated intestinal condition because both NLCs and CH-NLCs were totally destructed in the intestinal condition after 3 h. In the thiobarbituric acid test, the absorbance of milk-fortified NLC and CH-NLCs was lower than that of original milk. Based on these results, CH-NLCs showed great potential for iron fortification in milk. © 2017 Institute of Food Technologists®.

    Background: Food insecurity in sub-Saharan Africa and malnutrition constitute the main obstacles for successful treatment of people living with HIV/AIDS (PLWH). The aim of this study was to assess the effect of consuming daily 100 g RUTF (ready-to-use therapeutic food) as supplement, on body composition, anemia and zinc status of hospitalized PLWH in Senegal. Methods: A Controlled clinical trial was conducted in 65 PLWH randomly allocated to receive either standard hospital diet alone (Control group: n=33), or the standard diet supplemented with 100 g RUTF/day (RUTF group: n=32). Supplementation was continued at home during 9 weeks. Individual dietary intakes were measured and compared to the Recommended Dietary Allowances. Body composition was determined using Bio-Impedance Analysis. Hemoglobin was measured by HemoCue and plasma zinc (PZ) concentration by atomic absorption spectrometry. PZ was adjusted to infection (CRP and -+a1-AGP). All measures were conducted on admission, discharge and after 9 weeks home-based follow up. Results: 34 and 24 % of the patients in RUTF and Control groups were suffering from severe malnutrition (BMI 16 kg/m2), respectively. In both groups, more than 90 % were anemic and zinc deficiency affected over 50 % of the patients. Food consumed by the Control group represented 75, 14 and 55 % of their daily recommended intake (DRI) of energy, iron and zinc, respectively. When 100 g of RUTF was consumed with the standard diet, the DRI of energy and zinc were 100 % covered (2147 kcal, 10.4 mg, respectively), but not iron (2.9 mg). After 9 weeks of supplementation, body weight, and fat-free mass increased significantly by +11 % (p= 0.033), and +11.8 % (p= 0.033) in the RUTF group, but not in the Control group, while percentage body fat was comparable between groups (p=0.888). In the RUTF group, fat free mass gain is higher in the patients on ART (+11.7 %, n=14; p=0.0001) than in those without ART (+6.2 %, n= 6; p=0.032). Anemia decreased

    Operations research is mainly applied to decision making in industries and corporations using quantitative methods to optimize production. The applications of operations research in social sciences research or health research in HIV, service delivery, and program performance improvement are minimal. Considering the complexity of the HIV/AIDS epidemic, it is imperative to learn from operations research in scaling up HIV treatment, prevention, and intervention in resource-poor settings. In this article the author discusses the methodological issues in operations research within the context of HIV/AIDS research. The author also suggests a framework for using operations research in the field of HIV/AIDS research and program intervention.

    Full Text Available Adding micronutrient powders (MNP to complementary foods at the point of preparation (home fortification can improve micronutrient status of young children. Ensuring sustained access to MNPs at scale, however, remains challenging in many countries. The Global Alliance for Improved Nutrition (GAIN partnered with the National Institute of Nutrition (NIN in Vietnam to pioneer the distribution of a locally-produced MNP, provided for sale through the public health system with counseling on optimal infant and young child feeding practices by trained health workers. Different packaging options were available to adapt to caregivers’ disposable income. During the six-month pilot, 1.5 million sachets were sold through 337 health centers across four provinces, targeting children 6–59 months of age. Sales were routinely monitored, and a cross-sectional survey in 32 communes for caregivers (n = 962 and health staff (n = 120 assessed MNP coverage and compliance, five months after the start of distribution. A total of 404 caregivers among the 962 caregivers surveyed (i.e., 42% had visited the health center in the past year. Among them, 290 caregivers had heard about the product and a total of 217caregivers had given the MNP to their child at least once, representing a conversion rate from product awareness to product trial of 74.8%. The effective coverage (i.e., consumption of ≥3 sachets/child/week was 11.5% among the total surveyed caregivers and reached 27.3% amongst caregivers who visited health centers in the previous month. The MNP purchase trends showed that the number of sachets bought by caregivers was positively correlated with the wealth index. The pilot showed that providing MNPs for sale in packs of various quantities, combined with infant and young child feeding (IYCF counseling at the health center, is effective for groups accessing the health system.

    Polar lipids, such as monoglycerides and phospholipids, are amphiphilic molecules commonly used as processing and stabilization aids in the manufacturing of food products. As all amphiphilic molecules (surfactants, emulsifiers) they show self-assembly phenomena when added into water above a certain concentration (the critical aggregation concentration). The variety of self-assembly structures that can be formed by polar food lipids is as rich as it is for synthetic surfactants: micelles (normal and reverse micelles), microemulsions, and liquid crystalline phases can be formulated using food-grade ingredients. In the present work we will first discuss microemulsion and liquid crystalline phase formation from ingredients commonly used in food industry. In the last section we will focus on three different potential application fields, namely (i) solubilization of poorly water soluble ingredients, (ii) controlled release, and (iii) chemical reactivity. We will show how the interfacial area present in self-assembly structures can be used for (i) the delivery of functional molecules, (ii) controlling the release of functional molecules, and (iii) modulating the chemical reactivity between reactive molecules, such as aromas.

    Large improvements and advances in space food systems achieved during the Apollo food program are discussed. Modifications of the Apollo food system were directed primarily toward improving delivery of adequate nutrition to the astronaut. Individual food items and flight menus were modified as nutritional countermeasures to the effects of weightlessness. Unique food items were developed, including some that provided nutritional completeness, high acceptability, and ready-to-eat, shelf-stable convenience. Specialized food packages were also developed. The Apollo program experience clearly showed that future space food systems will require well-directed efforts to achieve the optimum potential of food systems in support of the physiological and psychological well-being of astronauts and crews.

  11. AIDS in the developing countries.

    Science.gov (United States)

    1988-01-01

    Without a medical miracle, it seems inevitable that the Acquired Immune Deficiency Syndrome (AIDS) pandemic will become not only the most serious public health problem of this generation but a dominating issue in 3rd world development. As a present-day killer, AIDS in developing countries is insignificant compared to malaria, tuberculosis, or infant diarrhea, but this number is misleading in 3 ways. First, it fails to reflect the per capita rate of AIDS cases. On this basis, Bermuda, French Guyana, and the Bahamas have much higher rates than the US. Second, there is extensive underreporting of AIDS cases in most developing nations. Finally, the number of AIDS cases indicates where the epidemic was 5-7 years ago, when these people became infected. Any such projections of the growth of 3rd world AIDS epidemics are at this time based on epidemiologic data from the industrialized rations of the north and on the assumption that the virus acts similarly in the south as it does in the US and Europe. Yet, 3rd world conditions differ. Sexually transmitted diseases usually are more prevalent, and people have a different burden of other diseases and of other stresses to the immune system. In Africa, AIDS already is heavily affecting the mainstream population in some nations. Some regions will approach net population declines over the next decade. How far their populations eventually could decline because of AIDS is unclear and will depend crucially on countermeasures taken or not taken over the next 1-2 years. In purely economic terms, AIDS will affect the direct costs of health care, expenses which are unrealistic for most 3rd world countries. Further, the vast majority of deaths from AIDS in developing countries will occur among those in the sexually active age groups -- the wage earners and food producers. Deaths in this age group also will reduce the labor available for farming and industry. AIDS epidemics also may have significant effects on foreign investment in the 3rd

  12. AIDS prevention: what are we talking about?

    Science.gov (United States)

    Chowdhury, A N

    1991-11-01

    A psychiatrist from Calcutta objects to the colonial culture which still dominates India. Specifically the call for prevention of AIDS and the spread of HIV made by developed countries, yet socioeconomic conditions in India hinder any prevention efforts. India faces other more common and preventable fatal diseases. The basic needs (food, shelter, health, and education) of most people cannot even be met. Thus an AIDS prevention program is an expensive luxury and probably would not reach those whose needs are already not met. 65% of AIDS cases are in Africa especially central Africa and almost 90% of AIDS cases in developing countries are in the most productive age group (20-49 years). The HIV/AIDS epidemic is indeed dealing countries an economic blow. For example, in 1988, AIDS related medical costs in the US stood at US$8.5 billion; lost wages US$55.6 billion; and research, education, and blood screening US$2.3 billion. Developing countries cannot absorb such an economic impact. The AIDS epidemic can strain a developing country's health system such as Zaire. For example, the cost of providing proper care for only 10 AIDS patients is higher than the entire budget of the largest hospital. Yet this hospital's physicians diagnose as many as 15 new cases daily. Economic loss/year due to AIDS deaths in Zaire will equal 8% of the gross national product by 1995. The poor often do not have access to health services. illiteracy (88%) in Brazil impedes AIDS prevention messages from reaching remote rural populations. Brazil already faces a high infant mortality rate and 33% of the population has malaria. Health and social problems in developing countries are so common that AIDS is just 1 more disease. Another obstacle to AIDS prevention in developing countries is that the poor cannot afford to buy condoms. The root cause of AIDS in developing countries is poverty.

  7. The Master Hearing Aid

    Science.gov (United States)

    Curran, James R.

    2013-01-01

    As early as the 1930s the term Master Hearing Aid (MHA) described a device used in the fitting of hearing aids. In their original form, the MHA was a desktop system that allowed for simulated or actual adjustment of hearing aid components that resulted in a changed hearing aid response. Over the years the MHA saw many embodiments and contributed to a number of rationales for the fitting of hearing aids. During these same years, the MHA was viewed by many as an inappropriate means of demonstrating hearing aids; the audio quality of the desktop systems was often superior to the hearing aids themselves. These opinions and the evolution of the MHA have molded the modern perception of hearing aids and the techniques used in the fitting of hearing aids. This article reports on a history of the MHA and its influence on the fitting of hearing aids. PMID:23686682

  12. Finding the Limits of Aid/Watch

    Directory of Open Access Journals (Sweden)

    Matthew Harding

    2011-11-01

    Full Text Available Commissioner of Taxation v Aid/Watch Incorporated is the latest of a series of recent cases in which the High Court of Australia has exhibited what might be described as a ‘generosity of spirit’ to would-be taxpayers whose charitable status has been called into question. In Aid/Watch, the Court ruled that an organisation formed to monitor and evaluate the delivery of foreign aid by Australian government agencies was a charity even though it was engaged, consistently with its objects, in the sorts of political activities that traditionally have been regarded as anathema to charity. This article considers where we might feasibly locate the boundaries of the High Court’s reasoning in Aid/Watch, in light of charity law as a whole. In other words, as a matter of charity law, what are the limits of Aid/Watch? Thinking about this question demands: (a some understanding of what the High Court in Aid/Watch said with certainty; and (b a wider review of charity law to see which of its rules and principles may bear upon cases about political purposes now that Aid/Watch has been decided.

    2017-11-01

    Biologist and Nobel Prize winner James Watson's quote, "We used to think that our fate was in our stars, but now we know that, in large measure, our fate is in our genes", represents the initial food for thought that revolutionized the way medications and active pharmaceutical ingredients are defined (Rocholl 1996). This fate engraved in the genetic material, as mentioned in Watson's quote, fueled a tremendous revolution wave in gene therapy. Gene therapy is a promising technology for treating genetic and acquired diseases by modulating the expression of a specific gene in the pathological cells. This is achieved by introducing a DNA sequence or other nucleic acid material or oligonucleotides to the target cell (Kay, 2011). Moreover, gene therapy contributes to correction of genetic defects, expression of therapeutic proteins, and inhibition of the synthesis of malignant proteins. In this review article, different non-viral gene delivery systems and their applications are discussed in detail. We reviewed and tabulated over 90 papers and 50 patents from 2006 to date discussing non-viral gene delivery technologies, innovation, and bench-to-bedside transformation. Furthermore, we are going to shed light on the lack of standardization in the design and characterization of non-viral gene delivery systems worldwide, which is a major concern in this research's field. This review would aid in getting an eagle eye view through non-viral gene delivery technologies during the past 20 years. Such a view, capturing the advances, the hurdles, and experimental details, would aid expert researchers in tuning their experimentation strategies and help newcomers better initially design their studies to generate solid and comprehensive results that can be reliable and reproducible.

    As HIV disease evolves into a chronic and manageable disease, monitoring trends in HIV/AIDS inpatient use will become an important tool clinicians can use to analyze the need for organizational changes in patient care delivery. Monitoring census trends can assist nurses in developing plans of care and evaluating outcome in HIV patients. Nurse managers of AIDS Specialty Units (ASUs) are at the forefront of identifying current inpatient use trends. This article investigates census trends in selected ASUs from the perspective of ASU nurse managers and describes the factors that nurse managers believe to have influenced census trends. Implications for further research are provided.

  18. Redefining global health-care delivery.

    Science.gov (United States)

    Kim, Jim Yong; Farmer, Paul; Porter, Michael E

    2013-09-21

    Initiatives to address the unmet needs of those facing both poverty and serious illness have expanded significantly over the past decade. But many of them are designed in an ad-hoc manner to address one health problem among many; they are too rarely assessed; best practices spread slowly. When assessments of delivery do occur, they are often narrow studies of the cost-effectiveness of a single intervention rather than the complex set of them required to deliver value to patients and their families. We propose a framework for global health-care delivery and evaluation by considering efforts to introduce HIV/AIDS care to resource-poor settings. The framework introduces the notion of care delivery value chains that apply a systems-level analysis to the complex processes and interventions that must occur, across a health-care system and over time, to deliver high-value care for patients with HIV/AIDS and cooccurring conditions, from tuberculosis to malnutrition. To deliver value, vertical or stand-alone projects must be integrated into shared delivery infrastructure so that personnel and facilities are used wisely and economies of scale reaped. Two other integrative processes are necessary for delivering and assessing value in global health: one is the alignment of delivery with local context by incorporating knowledge of both barriers to good outcomes (from poor nutrition to a lack of water and sanitation) and broader social and economic determinants of health and wellbeing (jobs, housing, physical infrastructure). The second is the use of effective investments in care delivery to promote equitable economic development, especially for those struggling against poverty and high burdens of disease. We close by reporting our own shared experience of seeking to move towards a science of delivery by harnessing research and training to understand and improve care delivery.

  1. Laos: rural economy threatened by AIDS.

    Science.gov (United States)

    Zola, A M

    1994-01-01

    Laos is a rural country in which more than 70% of the work force depends upon the agricultural sector for its livelihood. Crop production in Laos is a low-productivity, labor-intensive affair which is highly vulnerable to disruption by natural disasters and outbreaks of disease. Laos is also a crossroads for trade from Cambodia, China, Thailand, and Vietnam. While such trade has some positive effect upon the domestic economy, it also facilitates the spread of sexually transmitted diseases into Laos from neighboring countries with high rates of HIV infection. The northwestern trading corridor bordering Thailand, Myanmar, and China is of particular concern with regard to the spread of HIV. The Lao government identified eleven individuals infected with HIV and had officially reported only one case of AIDS to the World Health Organization (WHO) as of April 1992. Although WHO has not yet confirmed or projected the number of HIV-seropositive and AIDS cases in Laos, scant available data suggest that AIDS is concentrated in urban areas. Poverty and isolation will not, however, protect rural villages from HIV. The implications of a growing HIV/AIDS epidemic for rural social structures are considered. It is clear that such a situation could lead to agroeconomic dislocation and jeopardize national food security. The following measures are recommended to confront HIV/AIDS in the agricultural sector: change cropping systems, provide AIDS prevention education and technical assistance, and recruit village cadres to increase AIDS awareness among young Lao and care for the very ill.

    In the 1960s and early 1970s, many countries in South and Southeast Asia were the focus of world attention due to their frequent occurrence of food shortages. These shortages were met by large amounts of food imported through food aid or similar programmes. Several pessimistic predictions were made about the future of food security in Asia on the basis of the severity of these shortages. For example, the Asian Development Bank’s 1977 survey predicted increasing food grains defi cits unless re...

    The AEL (aid effectiveness literature) studies the effect of development aid using econometrics on macro data. It contains about 100 papers of which a third analyzes conditional models where aid effectiveness depends upon z, so that aid only works for a certain range of the variable. The key term...... in this family of AEL models is thus an interaction term of z times aid. The leading candidates for z are a good policy index and aid itself. In this paper, meta-analysis techniques are used (i) to determine whether the AEL has established the said interaction terms, and (ii) to identify some of the determinants...... of the differences in results between studies. Taking all available studies in consideration, we find no support for conditionality with respect to policy, while conditionality regarding aid itself is dubious. However, the results differ depending on the authors’ institutional affiliation....

    In selected typical Ecuatorian foods to be used in nutritional intervention programmes, we measured iron bioavailability in humans, with a double isotopic method. The interaction with some accompanied foods or beverages was also studied. Iron bioavailability from wheat flour foods was good (9%). When vermicelli soup was eaten together with lemonade sweetened with raw sugar cane, mean iron absorption was the highest (15%). Camomile infusion do not affect iron absorption from bread. At the same time, we will validate an in vitro iron availability technique comparing it with the results obtained in other laboratories involved in the present CRP and with the results obtained in the same foods with in vivo double isotopic. We will also start studies of in vitro zinc availability. (author). 26 refs, 2 figs, 7 tabs

    1987-01-01

    Acquired Immunodeficiency Syndrome (AIDS) is a worldwide epidemic that affects all countries, developing and industrialized. The impacts of AIDS range from social, cultural, psychological to the economic and political. The World Health Organization (WHO) has mobilized international and national interest and resources to work on AIDS control and prevention. AIDS spreads in 3 ways mother to child, through blood, and sexually. Screening blood supplies can prevent the spread of AIDS. In 1987, 105 countries reported 49,132 cases to WHO, and estimated indicated over 100,000 cases. WHO estimate that by 1991 there will be over 1 million cases worldwide. Infant mortality rates due to AIDS may be 10-20/1000 births where 10% of pregnant women are infected. Homosexual, or bisexual men and intravenous drug users from 20 to 49 year old make up most of the cases of AIDS in North and South America, Europe, and Australia. It is estimated that Africa has over 1 million AIDS infected people but accurate counts are not available. There have been a small number of cases reported in Asia, and most of these have resulted from contaminated blood. It is currently estimated that 10- 30% of HIV infected persons will develop AIDS, and 25-50% will develop an AIDS related disease within 5 years. The majority of HIV infected persons will develop AIDS within 10 years and the rest, AIDS related diseases. The cost of a patient can run for $50,000-150,000 in direct medical care in industrialized countries. Since most of the people infected are from 20-49 years of age, their most productive years, a country's social and economic development is threatened. Education is presently the only way to prevent the spread of AIDS, and therefore all governments, as well as health and medical professional must make a extraordinary commitment.

McAllister wrote: "Comic books can and have contributed positively to the discourse about AIDS: images that encourage true education, understanding and compassion can help cope with a biomedical condition which has more than a biomedical relevance" [1]. With this in mind, I combined a 23-narrator oral history and my personal memoir about an inpatient Chicago AIDS hospital unit in my book, Taking Turns: Stories from HIV/AIDS Care Unit 371. In doing so, I built upon the existing rich history of HIV/AIDS in comics, which this article will briefly describe. Although not a comprehensive review of the intersection of AIDS and comics, the book is a tour through influences that proved useful to me. In addition, in making my book, I faced a distinct ethical issue with regard to representing patient experiences with HIV/AIDS, and I describe here how I addressed it. © 2018 American Medical Association.

  1. Optimizing Cancer Care Delivery through Implementation Science

    Full Text Available The 2013 Institute of Medicine report investigating cancer care concluded that the cancer care delivery system is in crisis due to an increased demand for care, increasing complexity of treatment, decreasing work force and rising costs. Engaging patients and incorporating evidence-based care into routine clinical practice are essential components of a high quality cancer delivery system. However, a gap currently exists between the identification of beneficial research findings and application in clinical practice. Implementation research strives to address this gap. In this review, we discuss key components of high quality implementation research. We then apply these concepts to a current cancer care delivery challenge in women’s health, specifically the implementation of a surgery decision aid for women newly diagnosed with breast cancer.

    Full Text Available A self-contained, self-fitting hearing aid (SFHA is a device that enables the user to perform both threshold measurements leading to a prescribed hearing aid setting and fine-tuning, without the need for audiological support or access to other equipment. The SFHA has been proposed as a potential solution to address unmet hearing health care in developing countries and remote locations in the developed world and is considered a means to lower cost and increase uptake of hearing aids in developed countries. This article reviews the status of the SFHA and the evidence for its feasibility and challenges and predicts where it is heading. Devices that can be considered partly or fully self-fitting without audiological support were identified in the direct-to-consumer market. None of these devices are considered self-contained as they require access to other hardware such as a proprietary interface, computer, smartphone, or tablet for manipulation. While there is evidence that self-administered fitting processes can provide valid and reliable results, their success relies on user-friendly device designs and interfaces and easy-to-interpret instructions. Until these issues have been sufficiently addressed, optional assistance with the self-fitting process and on-going use of SFHAs is recommended. Affordability and a sustainable delivery system remain additional challenges for the SFHA in developing countries. Future predictions include a growth in self-fitting products, with most future SFHAs consisting of earpieces that connect wirelessly with a smartphone and providers offering assistance through a telehealth infrastructure, and the integration of SFHAs into the traditional hearing health-care model.

    1993-01-01

    The National AIDS Convention in South Africa (NACOSA) in October 1992 was the first real attempt to address HIV/AIDS. In Soweto, government, the African National Congress, nongovernmental organizations, and organized industry and labor representatives worked for 2 days to develop a national plan of action, but it did not result in a united effort to fight AIDS. The highest HIV infection rates in South Africa are among the KwaZulu in Natal, yet the Inkatha Freedom Party did not attend NACOSA. This episode exemplifies the key obstacles for South Africa to prevent and control AIDS. Inequality of access to health care may explain why health workers did not diagnose the first AIDS case in blacks until 1985. Migrant labor, Bantu education, and uprooted communities affect the epidemiology of HIV infection. Further, political and social polarization between blacks and whites contributes to a mindset that AIDS is limited to the other race which only diminishes the personal and collective sense of susceptibility and the volition and aptitude to act. The Department of National Health and Population Development's voluntary register of anonymously reported cases of AIDS specifies 1517 cumulative AIDS cases (October 1992), but this number is low. Seroprevalence studies show between 400,000-450,000 HIV positive cases. Public hospitals cannot give AIDS patients AZT and DDI. Few communities provided community-based care. Not all hospitals honor confidentiality and patients' need for autonomy. Even though HIV testing is not mandatory, it is required sometimes, e.g., HIV testing of immigrants. AIDS Training, Information and Counselling Centers are in urban areas, but not in poor areas where the need is most acute. The government just recently developed in AIDS education package for schools, but too many people consider it improper, so it is not being used. The poor quality education provided blacks would make it useless anyhow. Lifting of the academic boycott will allow South African

    The signal processing and fitting methods used for hearing aids have mainly been designed to optimize the intelligibility of speech. Little attention has been paid to the effectiveness of hearing aids for listening to music. Perhaps as a consequence, many hearing-aid users complain that they are not satisfied with their hearing aids when listening to music. This issue inspired the Internet-based survey presented here. The survey was designed to identify the nature and prevalence of problems associated with listening to live and reproduced music with hearing aids. Responses from 523 hearing-aid users to 21 multiple-choice questions are presented and analyzed, and the relationships between responses to questions regarding music and questions concerned with information about the respondents, their hearing aids, and their hearing loss are described. Large proportions of the respondents reported that they found their hearing aids to be helpful for listening to both live and reproduced music, although less so for the former. The survey also identified problems such as distortion, acoustic feedback, insufficient or excessive gain, unbalanced frequency response, and reduced tone quality. The results indicate that the enjoyment of listening to music with hearing aids could be improved by an increase of the input and output dynamic range, extension of the low-frequency response, and improvement of feedback cancellation and automatic gain control systems.

    The Eden Alternative® is a philosophy of care and transformational model aimed at increasing quality of life for nursing home residents by enhancing institutional environments and restructuring delivery of care. Restructured care consists of three fundamental components: resident care provided primarily by care aides, enhanced responsibilities for care aides, and consistent assignment of residents to care aides. Researchers have focused on resident and family satisfaction with the model, but there is limited research evaluating the impact of the model on nursing home employees. This article is focused on their experiences. Convenience and purposive sampling were used to recruit 22 care aides from five nursing homes in a western Canadian city. Experiential interview data were collected and analyzed utilizing constant comparison to identify common themes. Although care aides initially welcomed the restructuring, they described gradually becoming overwhelmed by the work, confined by consistent assignments, and isolated from colleagues and other residents. © The Author(s) 2014.

    2003-02-01

    If your company operates in a developing country, AIDS is your business. While Africa has received the most attention, AIDS is also spreading swiftly in other parts of the world. Russia and Ukraine had the fastest-growing epidemics last year, and many experts believe China and India will suffer the next tidal wave of infection. Why should executives be concerned about AIDS? Because it is destroying the twin rationales of globalization strategy-cheap labor and fast-growing markets--in countries where people are heavily affected by the epidemic. Fortunately, investments in programs that prevent infection and provide treatment for employees who have HIV/AIDS are profitable for many businesses--that is, they lead to savings that outweigh the programs' costs. Due to the long latency period between HIV infection and the onset of AIDS symptoms, a company is not likely to see any of the costs of HIV/AIDS until five to ten years after an employee is infected. But executives can calculate the present value of epidemic-related costs by using the discount rate to weigh each cost according to its expected timing. That allows companies to think about expenses on HIV/AIDS prevention and treatment programs as investments rather than merely as costs. The authors found that the annual cost of AIDS to six corporations in South Africa and Botswana ranged from 0.4% to 5.9% of the wage bill. All six companies would have earned positive returns on their investments if they had provided employees with free treatment for HIV/AIDS in the form of highly active antiretroviral therapy (HAART), according to the mathematical model the authors used. The annual reduction in the AIDS "tax" would have been as much as 40.4%. The authors' conclusion? Fighting AIDS not only helps those infected; it also makes good business sense.

  19. AIDS and economic disruption.

    Science.gov (United States)

    Johnson, G S

    1996-10-01

    Child and adult mortality increases in Cameroon due to AIDS will cause life expectancy to fall by as many as 8 years, from just over 50 to just over 40 years. The social consequences of AIDS include grieving, stigmatizing, and the large-scale disruption of family and community structures. Widows and widowers due to AIDS mortality are affected differently from each other, with the widows of men who have died from AIDS facing potential sociocultural and economic hardship. The economic consequences of AIDS in Bamenda and elsewhere in Cameroon will occur mainly through the epidemic's impact upon the size and quality of the labor force. By killing a significant number of male and female workers aged 15-60 years, AIDS will reduce the size and growth rate of the labor force. Despite, rapid population growth, labor is a relatively scarce factor of agricultural production in Cameroon. The spread of HIV in rural areas, combined with the intensity and scarcity of agricultural labor, suggests that AIDS will have an impact upon production and per capita incomes, and increase the already high rates of hunger and absolute poverty. In the context of HIV/AIDS, young people must be empowered to make informed decisions about sex. Adolescents are most at risk because they tend to experiment more than married couples and have many sex partners. Sexual activity begins as early as age 8 years and penetrative sex at age 13 or earlier. The author considers the factors which encourage adolescents to engage in sexual activities.

  9. Puppetry and AIDS education.

    Science.gov (United States)

    Friedman, G

    1992-01-01

    The effectiveness of puppet theater in communicating information about acquired immunodeficiency syndrome (AIDS) has been demonstrated in a project launched in 1988 by the African Research and Education Puppetry Program (AREPP). Puppetry is a vital part of the Bambara, Bozo, and Yoruba cultures. "Puppets Against AIDS" tells the story of a condom refuser who transmits the AIDS virus to his wife and their infant. An evaluation conducted by social epidemiologists in 1989 found the production to be comprehensive in its educational messages and effective in contributing to the audiences' knowledge and intended behavioral changes. A discussion period follows the production. The show was subsequently incorporated into an existing community-based AIDS education program. Because AIDS touches upon sensitive and often taboo areas of social life, the dissemination of information through puppets is not perceived as threatening as interpersonal interaction.

  14. HIV / AIDS and tourism.

    Science.gov (United States)

    Forsythe, S

    1999-01-01

    Since it tends to be significantly affected by HIV/AIDS, the tourism sector is a likely target for HIV/AIDS interventions in many countries. The tourist industry is at particular risk from the pandemic because of the mobility of the work force, the presence of sex tourists, and the heavy reliance of many countries upon tourism revenues. Indeed, tourism is one of the largest and fastest growing industries in many countries. Some people have speculated that potential tourists' fear of AIDS could discourage them from visiting certain countries, while others have even suggested that tourism should be discouraged because the industry contributes to the spread of HIV/AIDS. When traveling, tourists often take risks that they would not take at home. They tend to drink more, use drugs more, and be generally more adventurous while on holiday. Such adventures often include taking sexual risks. When tourists have sex with prostitutes, hotel staff, and others in the local population, a bridge can be created for HIV to cross back and forth between the tourist's home country and the tourist destination. The author reviews selected studies on the relationship between HIV/AIDS and tourism. Overall, the existing literature offers no definitive evidence that AIDS has had any lasting impact upon the tourism industry anywhere in the world. Rather, promoting a healthy tourism industry and HIV/AIDS prevention are likely complementary in many ways.

    Fang, Y L; Chen, X G; W T, Godbey

    2015-11-01

    As a promising strategy to aid or replace tissue/organ transplantation, gene delivery has been used for regenerative medicine applications to create or restore normal function at the cell and tissue levels. Gene delivery has been successfully performed ex vivo and in vivo in these applications. Excellent proliferation capabilities and differentiation potentials render certain cells as excellent candidates for ex vivo gene delivery for regenerative medicine applications, which is why multipotent and pluripotent cells have been intensely studied in this vein. In this review, gene delivery is discussed in detail, along with its applications to tissue engineering and regenerative medicine. A definition of a stem cell is compared to a definition of a stem property, and both provide the foundation for an in-depth look at gene delivery investigations from a germ lineage angle. © 2014 Wiley Periodicals, Inc.

    Cohen, B.A.; Pomeranz, S.; Rabinowitz, J.G.; Rosen, M.J.; Train, J.S.; Norton, K.I.; Mendelson, D.S.

    1984-07-01

    Fifty-two patients with pulmonary complications of acquired immunodeficiency syndrome (AIDS) were studied over a 3-year period. The vast majority of the patients were homosexual; however, a significant number were intravenous drug abusers. Thirteen different organisms were noted, of which Pneumocystis carinii was by far the most common. Five patients had neoplasia. Most patients had initial abnormal chest films; however, eight patients subsequently shown to have Pneumocystis carinii pneumonia had normal chest films. A significant overlap in chest radiographic findings was noted among patients with different or multiple organisms. Lung biopsy should be an early consideration for all patients with a clinical history consistent with the pulmonary complications of AIDS. Of the 52 patients, 41 had died by the time this report was completed.

    Full Text Available Food allergy is an important public health problem affecting 5% of infants and children in Korea. Food allergy is defined as an immune response triggered by food proteins. Food allergy is highly associated with atopic dermatitis and is one of the most common triggers of potentially fatal anaphylaxis in the community. Sensitization to food allergens can occur in the gastrointestinal tract (class 1 food allergy or as a consequence of cross reactivity to structurally homologous inhalant allergens (class 2 food allergy. Allergenicity of food is largely determined by structural aspects, including cross-reactivity and reduced or enhanced allergenicity with cooking that convey allergenic characteristics to food. Management of food allergy currently focuses on dietary avoidance of the offending foods, prompt recognition and treatment of allergic reactions, and nutritional support. This review includes definitions and examines the prevalence and management of food allergies and the characteristics of food allergens.

Specifically, grants are found to impair the functioning of the bureaucracy, whereas loans are not. The negative impact of grants is larger when they are given as budget support...... rather than as assistance for specific projects or for programmes in general.

  3. AIDS in Africa.

    Wilson, D; Armstrong, M; Lavelle, S

    1991-01-01

    Works on epidemiological, and social and behavioral science aspects of AIDS prevention and support in Africa are reviewed from the 7th Conference on AIDS. Participants were especially concerned with why AIDS spreads at disparate rates in different countries and regions of the world. Research on the casual factors of the spread of HIV generally focused upon patterns of sex behavior, the presence of other STDs, and the effect of circumcision. The roles of certain vaginal tightening agents used by Zairian prostitutes, vaginal bruising and bleeding, sex during menses, and oral contraception were also considered. Further, participants explored the possibility of a more coordinated, integrated approach to research and intervention development between the medical and social disciplines, and expressed the overall need for concurrent mass education interventions. In the face of ever increasing rates of HIV infection, including vertical transmission, making condoms ubiquitous, affordable, and highly publicized should garner higher general acceptance and use rates in these populations. Papers and models on the micro- and macro-socioeconomic impact of AIDS were finally discussed, followed by recommendations for a complete reassessment and reworking of policy for AIDS prevention. AIDS activities should, in fact, be integrated into the daily fabric of society, with prevention measures considered an ultimate necessity for social survival.

    1997-12-01

    Full Text Available HIV infection and AIDS is increasingly becoming a major public health problem in our country. Currently, the reported cases represent only the 'tip of the iceberg' of the problem. In view of the fact that no cure or vaccine for the disease has yet been found, spreading knowledge and removing misconceptions is about the only way that AIDS can be effectively tackled.This handbook, developed by Prof. Shankar Chowdhury and associates, seeks to address all levels of medical and non-medical AIDS workers, as well as the layman. It deals with topics ranging from biology of the virus, symptoms and transmission of disease, to prevention, counselling for infected persons and action plan for AIDS education.The biology of the virus and the immune system is described in simple terms, as well as methods of testing for HIV, and what these test results mean. The progression of disease in adults and children, development of symptoms, diagnostic criteria for AIDS, treatment and outcome of disease is dealt with. How AIDS spreads between people, and the health risk for health workers and families is examined. The various ways in which transmission of HIV can be prevented is looked at in detail, including public health measures, national and internatonal action, and ethical and human rights issues involved.

    An international colloquium on AIDS held near Paris from October 26-28, 1989, unlike the World Conference on AIDS in Montreal the year before, was able to find reasons for optimism. Significant progress was reported in immunotherapy and in chemotherapy. Successful experiments in vaccinating monkeys against the AIDS virus were reported from the US, France, and Zaire. Time is needed to prove the efficacy of the vaccines because of the slow development in AIDS. A vaccine is being tested by Jonas Salk and collaborators in 75 seropositive volunteers who do not yet show full blown disease but who have very low levels of T4 lymphocytes. Plans are underway for a larger test on 500 seropositive patients at different stages of infection. According to Salk, the new chemical and logical approach toward AIDS will allow combinations of immunotherapy and chemotherapy to destroy the virus. R. Gallo of France listed as accomplishments of the past year a better understanding of the virus, improved case management techniques, increased ability to control Kaposi's sarcoma, considerable progress in the search for a vaccine, and detection of immune proteins that affect the virus. New biological markers permit establishment of correlations between cellular modifications and the progress of the disease as well as the precise effects of treatment. The new immune system drugs immuthiol and DDI are expected to reach the market soon. Patients very soon will be able to receive less toxic alternative treatments, which can be combined for greater efficacy once their toxic interactions are understood.

  19. Women and AIDS: introduction.

    Around the world, more and more women--principally poor women of color--are being diagnosed with and are dying of AIDS, the acquired immune deficiency syndrome. Yet, effective and appropriate prevention programs for women are sorely missing from the global program to control AIDS. To help us understand why this gap exists, and what we must do to close it, the three articles in this issue focus on women and AIDS. Examining the situation in such countries as Zimbabwe and South Africa, as well as in other economically underdeveloped and developed regions, the authors argue that women with the least control over their bodies and their lives are at greatest risk of acquiring AIDS. For example, the high rate of infection among women in Africa cannot be understood apart from the legacy of colonialism (including land expropriation and the forced introduction of a migrant labor system) and the insidious combination of traditional and European patriarchal values. Only by recognizing the socioeconomic and cultural determinants of both disease and sexual behavior, and only by incorporating these insights into our AIDS prevention programs, will we be able to curb the spread of this lethal disease.

    Radiotracer-aided studies were made of the fate and persistence of Thiram, used as a seed dresser and Ziram used as a foliar spray and their effects on soil fertility and plant growth. Thiram applied as a seed dresser had no inhibitory effect on (a) seedling height and rhizosphere microflora of barley, (b) soil microflora, (c) nodulation of cowpea plants. The uptake of 35 S radioactivity at 20-day stage was 0.3% of the total applied as 35 S thiram. Thiram as such was not present in barley or maize plants at any of the growth stages up to grain formulation but was converted into DDC-glucoside, DDC-alamine, fungicide X and TTCA. The quantity of these decreased in barley and maize with time and were in negligible amounts at grain stage. The sulphur from thiram found its way into sulphur-containing metabolites like protein, amino acids, sulfolipids, etc. Ziram, a foliar spray fungicide was also converted into DDC-conjugates and the amounts of residue were negligible at harvest time both in rice and groundnut. Thiram degraded more rapidly in unsterilized soils than in sterilized soil, thus indicating biodegradation. The fungicide is more persistent in sandy than in laterite and alluvial soils. Microbial degradation of thiram was shown by comparing persistence of 35 S thiram in sterilized and unsterilized soils. A Pseudomonas sp. isolated from soil was capable of degrading thiram and ziram and DDC-aminobutyric acid was the major polar metabolite. The appearance of similar degradation products with these dialkyl dithiocarbamates indicated that they have some common metabolic pathway

    Full Text Available Probiotics are live microorganisms that, when administered in adequate amounts, confer a health benefit on the host, mainly through the process of replacing or including beneficial bacteria in the gastrointestinal tract. Fermented dairy foods such as yogurt, fermented milk and cheese are the major vehicle in delivering probiotics, and probiotic delivery have been traditionally associated with these fermented dairy foods. Additionally, many other non-dairy probiotic products and non-food form such as capsules, pills and tablets are also available and some of these non-food forms are highly popular among the consumers. Certain non-dairy probiotic foods, especially beverages that are non-fermented products, can also play an important role in probiotic delivery. There is an increasing demand for non-dairy probiotic foods (both fermented and non-fermented including fruit and vegetable juices, soy and certain cereal products due to vegetarianism, lactose intolerance and dairy allergies, as well as interest in low cholesterol foods. In this context, this review mainly focus on the different types of probiotic food products including beverages with special reference to their viability followed by a brief account on the applicability of using fermented and non-fermented beverage products in probiotic delivery.

    Adverse food reactions are common in the general population. Nevertheless, our knowledge of the structure of food allergens and of the mechanisms involved is poor. In 1995 the European Academy of Allergology and Clinical Immunology suggested a classification based on the causative pathogenic mechanism. According to this classification, non-toxic reactions can be divided into food allergies when they recognize immunological mechanisms and food intolerance when there are no immunological implications. The treatment of food intolerance is avoidance of the particular food. There are specific treatments for some food intolerance (beta-galactosidases for the management of lactose intolerance).

    A frequent complication of the acquired immunodeficiency syndrome (AIDS) is AIDS dementia complex (ADC). The authors evaluated seven patients with AIDS (aged 28-55 years, all male) for ADC by psychiatric evaluation, neuropsychological testing, CT scanning, and IMP-SPECT. Six of seven patients exhibited cognitive or behavioral abnormalities. Neuropsychological testing showed general deficits but no cases of explicit dementia. SPECT showed marked abnormalities in two cases: posterior temporal-parietal diminution of tracer uptake in one case (posterior/anterior=0.81) and marked right/left subcortical asymmetry (1.17) in the other. In three additional cases there was asymmetric tracer uptake in the subcortical and parietal regions. CT findings were normal in all seven cases. The authors conclude that functional imaging with the use of IMP-SPECT may be a useful method to follow ADC progression and response to therapy

    Full Text Available The HIV/AIDS epidemic represents the most serious public health problem in India. There is no denial of the enormity of the problem. The prevalence of infection in all parts of the world highlights the spread from urban to rural areas and from high risk to general population. It is esti­mated that as on end of year 2004, 39.4 million people were infected with the virus. Migration of labour, low lit­eracy levels leading to low awareness, gender disparities, prevalence of sexually transmitted diseases and reproduc­tive tract infections are some of the factors attributed to the spread of HIV/AIDS.4.9 million ( 4.3 million - 6.4 million people have aquired HIV infection only in one year of span - 2004. The global AIDS epidemic killed 3.1 million ( 2,8 million- 3.5 million people in the past year.

GDMs are a new form of IT-enabled client-specific investment promoting services provision integration with clients by exploiting client proximity and time......-zone spread allowing for 24/7 service delivery and access to resources. Based on comprehensive data we show that providers are likely to establish GDM configurations when clients value access to globally distributed talent pools and speed of service delivery, and in particular when services are highly...... commoditized. Findings imply that coordination across time zones increasingly affects international operations in business-to-business and born-global industries....

    The increase in obesity prevalence highlights the need for a more comprehensive understanding of the neural systems controlling food intake; one that extends beyond food intake driven by metabolic need and considers that driven by higher-order cognitive factors. The hippocampus, a brain structure involved in learning and memory function, has recently been linked with food intake control. Here we examine whether administration of the adiposity hormone leptin to the dorsal and ventral sub-regions of the hippocampus influences food intake and memory for food. Leptin (0.1 μg) delivered bilaterally to the ventral hippocampus suppressed food intake and body weight measured 24 h after administration; a higher dose (0.4 μg) was needed to suppress intake following dorsal hippocampal delivery. Leptin administration to the ventral but not dorsal hippocampus blocked the expression of a conditioned place preference for food and increased the latency to run for food in an operant runway paradigm. Additionally, ventral but not dorsal hippocampal leptin delivery suppressed memory consolidation for the spatial location of food, whereas hippocampal leptin delivery had no effect on memory consolidation in a non-spatial appetitive response paradigm. Collectively these findings indicate that ventral hippocampal leptin signaling contributes to the inhibition of food-related memories elicited by contextual stimuli. To conclude, the results support a role for hippocampal leptin signaling in the control of food intake and food-related memory processing.

    Little is known about impacts of familial AIDS on abuse and sexual health outcomes amongst adolescents. Objectives were to determine whether familial AIDS is: (1) associated with severe physical, emotional, and sexual abuse; (2) associated with transactional sexual exploitation; and (3) explore whether relationships between familial AIDS and transactional sex are mediated by extreme poverty and abuse. Adolescent self-report study in deprived South African communities. A 2009 follow-up of a 2005 study achieved 71% retention (n = 723). The 2009 sample included AIDS-orphaned (n = 236), other-orphaned (n = 231), and non-orphaned (n = 220) adolescents, whose primary caregivers were AIDS sick (n = 109), other sick (n = 147), and healthy (n = 220). Abuse and transactional sex were measured using widely used and validated self-report measures. AIDS orphanhood and parental AIDS sickness predicted emotional and physical abuse and transactional sexual exploitation. Orphanhood or parental sickness by non-AIDS causes, and having healthy caregivers, did not predict any abuse outcomes. Adolescents "dually" affected by AIDS orphanhood and sickness showed a 3-fold likelihood of severe emotional and physical abuse and, amongst girls, a 6-fold likelihood of transactional sexual exploitation, compared with those in healthy families. Heightened risk of transactional sex amongst adolescents in AIDS-affected families was mediated by extreme poverty and abuse exposure. In combination, the effects of familial AIDS, food insecurity, and exposure to abuse raised prevalence of transactional sex amongst girls from 1% to 57%. Adolescents from AIDS-affected families are highly vulnerable to severe physical and emotional abuse and transactional sex. This has implications for policy and programming in child protection and HIV prevention services.
