This paper attempts to predict food shortages in advance from the analysis of rainfall during the monsoon months along with other inputs used for crop production, such as land used for cereal production, percentage of area covered under irrigation and fertiliser use. We used six binary classification data mining models viz., logistic regression, Multilayer Perceptron, kernel lab-Support Vector Machines, linear discriminant analysis, quadratic discriminant analysis and k-Nearest Neighbors Network, and found that linear discriminant analysis and kernel lab-Support Vector Machines are equally suitable for predicting per capita food shortage with 89.69 % accuracy in overall prediction and 92.06 % accuracy in predicting food shortage ( true negative rate). Advance information of food shortage can help policy makers to take remedial measures in order to prevent devastating consequences arising out of food non-availability.

Irradiation changes the normal living process of cells and the structure of molecules. It is good for food preservation because it kills off many of the microorganisms in the product and makes the remainder more sensitive to antimicrobial factors prevailing after the radiation treatment. It offers more benefits than conventional preservation in that it increases storage stability and quality of foodstuffs with the minimum use of energy. Good storage quality gives way to wider distribution of food, alleviates the world's food shortage, and improves food supplies. Research proved that irradiation increased the quality of subtropical fruits, spices, fish, and meat. No refrigeration is needed to store meat, poultry and fish preserved by the combination of irradiation and mild heat treatment. Nuclear technology can also be applied to destroy harmful insects, to sterilize food, to inhibit the sprouting of root crops, and to control ripening in stored fruits and vegetables. Based on the above potentials of irradiation, the prospect of nuclear application in food technology is promising.

Full Text Available Domestic water shortages are distressing many urban areas in developing countries and require well planned and sustainable coping strategies in order to bequeath citizens decent lives. The objectives of this paper were to identify water related civil society groups present in Gweru; reveal devised coping strategies to combat water shortages and household food insecurity; and challenges faced by civil society and residents in obtaining sustainable coping strategies. A survey was conducted through interviews, questionnaires and observations as data collection instruments. The findings show that residents relied on borehole drilled in their respective areas by the municipality, Non-Governmental Organisations (NGOs and through individual initiatives. Although public boreholes were available, they were found at an average of only two in a given residential area, regardless of its population. Residents also collected water in containers during late hours of the night or early hours of the day. Gweru residents in addition devised strategies to cope with household food insecurity caused by water shortages and high monthly water bills. Combined with the aforementioned water shortage coping strategies, the stratagem by residents included coming up with payment plans, denying city personnel access into their premises for water disconnection; and self-reconnection in the event of disconnection. Community gardens initiated by Non-Governmental Organisations and food imports from neighbouring countries were some of the adaptive mechanisms dealing with household food insecurity. However, despite resolute efforts by civil society and residents to muddle through water supply and food security challenges, the city needs financial aid to enhance service provision that does not solely relying on residents. Financial injection and investment in sustainable alternative water sources for the city’s multiple uses will go a long way in solving the water shortages and

While agriculture places the greatest demand on water resources, increasing agricultural production is worsening a global water shortage. Reducing the cultivation of water-consuming crops may be the most effective way to reduce agricultural water use. However, when also taking food demand into consideration, sustaining the balance between regional water and food securities is a growing challenge. This paper addresses this task for regions where water is unsustainable for food production (Beijing-Tianjin-Hebei Region for example) by: (i) assessing the different effects of wheat and maize on water use; (ii) analyzing virtual water and virtual land flows associated with food imports and exports between Beijing-Tianjin-Hebei and elsewhere in China; (iii) identifying sub-regions where grain is produced using scarce water resources but exported to other regions; and (iv) analyzing the potentiality for mitigating water shortage via Land-Water-Food Nexus. In the Beijing-Tianjin-Hebei Region, the study reveals that 29.76 bn m 3 of virtual water (10.81 bn m 3 of blue virtual water) are used by wheat and maize production and 8.77 bn m 3 of virtual water used in nearly 2 million ha of cropland to overproduce 12 million ton of maize for external food consumption. As an importing-based sub-region with high population density, Beijing & Tianjin imported mostly grain (wheat and maize) from Shandong Province. Then, Hebei Province, as an exporting-based sub-region with severe water shortage, overproduced too much grain for other regions, which aggravated the water crisis. To achieve an integrated and sustainable development of the Beijing-Tianjin-Hebei Region, Hebei Province should stop undertaking the breadbasket role for Beijing & Tianjin and pay more attention to groundwater depletion. The analysis of the Land-Water-Food Nexus indicates how shifts in cultivated crops can potentially solve the overuse of water resources without adverse effects on food supply

As an importing-based sub-region with high population density, Beijing and Tianjin (BT) imported mostly grain (wheat and maize) from Shandong (SD). Whereas, Hebei (HB), as an exporting-based sub-region with sever water shortage, overproduced too much grain for other regions (like Central area), which aggravated water crisis. To achieve Beijing-Tianjin-Hebei's integrated and sustainable development, HB should not undertake the breadbasket role for BT but pay more attention to groundwater depletion. The analysis of the Land-Water-Food Nexus indicates how shifts in the cultivated crops can potentially solve the overuse of water resources without adverse effect on food supply, and provides meaningful information to support policy

The brain regulates energy homeostasis in the organism. Under resource shortage, the brain takes priority over peripheral organs for energy supply. But can the brain also down-regulate its own consumption to favor survival? We show that the brain of Drosophila specifically disables the costly formation of aversive long-term memory (LTM) upon starvation, a physiological state required for appetitive LTM formation. At the neural circuit level, the slow oscillations normally triggered in two pairs of dopaminergic neurons to enable aversive LTM formation were abolished in starved flies. Transient artificial activation of these neurons during training restored LTM formation in starved flies but at the price of a reduced survival. LTM formation is thus subject to adaptive plasticity that helps survival under food shortage.
China's water shortage could shake world food security.

This report indicates the global concern about China's water shortages and describes basin supplies, global availability of grain, and reasons for water losses. There is little precise data on how land productivity will be affected by declines in irrigation. Reports from the "China Daily" indicate that the 1995 grain harvest in Shandong province declined by 2.7 million tons (food for 9 million people) due to water failures of the Yellow River. A delegate at the 1998 National People's Congress pointed out that rural villages nationwide had shortages of 30 billion cu. m and losses of 20 million tons of grain production. About 70% of grain harvests rely on irrigation. Water demand for residential use and industrial use is likely to increase and compete with farm use. One unlikely option is to divert irrigation water to cities as needed and import grain. The entire agricultural, energy, and industrial economies need to be made more water efficient. Agriculture will need to produce more water efficient crops and livestock products and less water intensive energy supplies. Another alternative is to divert water from one location to another. Water pricing could reinforce efficiency of use. Use of composting toilets could reduce human residential water demand. Urban capacity building should rely on separate industrial and residential wastewater systems. Investing in technologies for industry can reduce water demand among paper and steel producers. The fastest growing grain market is in North Africa and the Middle East. Trends in principal grain exporting countries with 85% of global exports indicate no growth in grain production for export since 1980.
Recent food shortage is associated with leprosy disease in Bangladesh: a case-control study.

Sabiena G Feenstra

Full Text Available BACKGROUND: Leprosy is remaining prevalent in the poorest areas of the world. Intensive control programmes with multidrug therapy (MDT reduced the number of registered cases in these areas, but transmission of Mycobacterium leprae continues in most endemic countries. Socio-economic circumstances are considered to be a major determinant, but uncertainty exists regarding the association between leprosy and poverty. We assessed the association between different socio-economic factors and the risk of acquiring clinical signs of leprosy. METHODS AND FINDINGS: We performed a case-control study in two leprosy endemic districts in northwest Bangladesh. Using interviews with structured questionnaires we compared the socio-economic circumstances of recently diagnosed leprosy patients with a control population from a random cluster sample in the same area. Logistic regression was used to compare cases and controls for their wealth score as calculated with an asset index and other socio-economic factors. The study included 90 patients and 199 controls. A recent period of food shortage and not poverty per se was identified as the only socio-economic factor significantly associated with clinical manifestation of leprosy disease (OR 1.79 (1.06-3.02; p = 0.030. A decreasing trend in leprosy prevalence with an increasing socio-economic status as measured with an asset index is apparent, but not statistically significant (test for a trend: OR 0.85 (0.71-1.02; p = 0.083. CONCLUSIONS: Recent food shortage is an important poverty related predictor for the clinical manifestation of leprosy disease. Food shortage is seasonal and poverty related in northwest Bangladesh. Targeted nutritional support for high risk groups should be included in leprosy control programmes in endemic areas to reduce risk of disease.

Fatty liver is associated with alcohol habits and/or overweight/obesity. We challenged several lifestyle features associated with fatty liver and, particularly, with non-alcoholic fatty liver disease (NAFLD). Among them, sleep shortage as a result of nightlife habits and a preference for plus-size fashion were assessed. The latter consists of fashionable plus-sized clothing for actual individuals' size and reflects a frequent attitude of some social or age groups, conceivably indicating more global and widespread trend and behaviour. We studied a group of 708 non-diabetic youngsters, 458 women and 250 men, 21.72 ± 3.71 years old (range 15-35 years), referred for minor digestive ailments for clinical assessment, ultrasound detection of fatty liver and nutritional counselling. Details of personal history regarding lifestyle, food intake frequency and alcohol intake, dietary and physical exercise profile, sleep duration and clothing preferences were recorded. The prevalence of NAFLD in this cohort of youngsters is 67/708 (9.4%). Even if it is quantitatively very low in both groups, the average alcohol intake, always below 20 g/day, is greater in NAFLD subjects (5.83 ± 4.32 g) vs. subjects with normal liver (2.02 ± 3.20 g). The number of meals/day and adherence to a Mediterranean diet profile are smaller in NAFLD subjects. By multiple regression, BMI, sedentary life, plus-sized clothing for their actual size, sleep shortage and lower frequency of daily food intake are associated with the presence of NAFLD. Onset and continuation of fatty liver disease, beyond food and exercise quantity and quality, with their effects on obesity, may also be associated with other aspects of lifestyle. © 2015 John Wiley & Sons A/S.

Montgomery, M. J.; Baylis, K.; Evans, T. P.

2016-12-01

Climate change is predicted to have negative impacts on agriculture and food security in many parts of sub-Saharan Africa. Regional and temporal climate variability will disburse these effects, creating opportunities to mitigate food shortages through well-studied international, regional, and national food flows and associated food prices. However, most food products consumed and traded by rural smallhold farmers rely on local market exchanges that take place outside the scope of prevalent regional and national market analysis. There is little empirical evidence on these rural markets outside of their potential for smallholder agribusiness. However, they offer an unopened window into local food supply and the nuances of food movements in rural areas. Our research explores how to analyze the cost and availability of food products in rural markets and their connection with each other, as well as with nearby households' food security. This new approach of using food markets as a unit of analysis necessitates a new framework that groups markets based on a hierarchy of variables relevant to their role as food movers and suppliers. In our research, we collected price and source data for 22 commodities bought and sold within 52 rural markets in 12 districts spatially distributed throughout Zambia. We continue to collect data via phone interviews with 206 traders and market managers within these markets each month. We used this data to develop a typology of stationary rural food markets based on their size in terms of traders and buyers, the diversity of commodities available year-round and seasonally, their price transmission with other markets, and their trading scheme and governance. The result is a dynamic framework with varying weights on each variable that classifies which characteristic of markets under which conditions increase their potential for local food shortage resilience and mitigation. We also allocate for commodity-specific scenarios to allow for modeling

Our aim was therefore, to investigate cross-sectional and prospective associations between TV viewing habits and food preferences and habits, respectively. We hypothesized that more TV viewing was associated with less healthy concomitant and future food preferences and food habits. Data are from the Danish part of European Youth Heart Study (EYHS) I and II, a prospective cohort study conducted among 8-10-year-old and 14-16-year-old Danes in 1997-98. Six years later 2003-04 the 8-10-year-olds were followed up at age 14-16 years, and a new group of 8-10-year olds were included. Data were analysed using mixed linear regression analysis. Cross-sectional analyses included 697 8-10-year-olds and 495 14-16-year-olds. Prospective analyses included 232 pupils with complete data at baseline and follow-up. Associations between TV viewing habits and the sum of healthy food preferences (ΣHFP), and the sum of healthy food habits (ΣHFH), respectively, were examined. Inverse cross-sectional associations between TV viewing (h/day) and both ΣHFP and ΣHFH were present for both the 8-10-year-old and the 14-16-year-old boys and girls. The frequency of meals in front of the TV (times/week) was also inversely associated with ΣHFP among 8-10-year-old boys, and with ΣHFH in all sex- and age groups. Among girls, baseline TV viewing (h/day) was directly associated with adverse development in the ΣHFP during follow-up. The concomitant 6-year changes in ΣHFH and TV viewing (h/day) were inversely associated in boys. Long time spent on TV viewing, and possibly to a lesser degree, frequent consumption of meals during TV viewing, seem to be associated with generally

Drug shortages have significantly increased over the past decade. There are limited data describing how shortages impact medical toxicology of drugs. To characterize drug shortages affecting the management of poisoned patients. Drug shortage data from January 2001 to December 2013 were obtained from the University of Utah Drug Information Service. Shortage data for agents used to treat poisonings were analyzed. Information on drug type, formulation, reason for shortage, shortage duration, marketing, and whether the drug was available from a single source was collected. The availability of a substitute therapy and whether substitutes were in shortage during the study period were also investigated. Of 1,751 shortages, 141 (8.1%) impacted drugs used to treat poisoned patients, and as of December 2013, 21 (14.9%) remained unresolved. New toxicology shortages increased steadily from the mid-2000s, reaching a high of 26 in 2011. Median shortage duration was 164 days (interquartile range: 76-434). Generic drugs were involved in 85.1% of shortages and 41.1% were single-source products. Parenteral formulations were often involved in shortages (89.4%). The most common medications in shortage were sedative/hypnotics (15.6%). An alternative agent was available for 121 (85.8%) drugs; however, 88 (72.7%) alternatives were also affected by shortages at some point during the study period. When present, the most common reasons reported were manufacturing delays (22.0%) and supply/demand issues (17.0%). Shortage reason was not reported for 48.2% of drugs. Toxicology drug shortages are becoming increasingly prevalent, which can result in both suboptimal treatment and medication errors from using less familiar alternatives. Drug shortages affected a substantial number of critical agents used in the management of poisoned patients. Shortages were often of long duration and for drugs without alternatives. Providers caring for poisoned patients should be aware of current shortages and
Economic Impacts of Power Shortage

Full Text Available The electricity industry is a basic industry of the national economy. It has experienced several large-scale power shortages, hard power shortage and soft power shortage, which have brought a great threat to China’s sustainable economic development. To solve this problem better, it is necessary to make a quantitative assessment of the economic impacts of power shortage. The CGE model is commonly used for simulating economic shocks and policy effects. It describes supply, demand and equilibrium in different markets by simulating the economic mechanism through a set of equations. Once changed, the exogenous variables will affect a certain part of the system and then the whole system, leading to changes in quantities and prices. The equilibrium state will also change from one to another. A static CGE model is built in this paper, and the Social Accounting Matrix (SAM of eight sectors of China in 2007 is compiled, in order to simulate the economic impacts of hard power shortage and soft power shortage. Simulation results show that the negative effects of power shortage on economic development are very significant, and the effects vary in different sectors. Especially, under the background of hard power shortage, the industrial sector suffers most. The economic cost of power shortage is considerable, and the main reason for it is the specific administrative pricing system in China. The low electricity price in the long term will lead to insufficient construction and hard power shortage; moreover, that in the short run would result in soft power shortage. In order to solve the problem of power shortage completely, power system reform is inevitable.

Full Text Available Orientation: South Africa is currently experiencing a serious shortage of skilled workers. It has a negative effect on South Africa’s economic prospects and on global participation in South Africa (SA. This skills shortage severely affects socioeconomic growth and development in SA. Research purpose: This study focuses on the causes and effects of the skills shortages in South Africa. Motivation for the study: The researchers undertook this study to highlight the role that skilled foreign workers can play in supplementing the shortage of skilled workers in South Africa. The shortage is partly because of the failure of the national education and training system to supply the economy with much-needed skills. Research design, approach and method: The researchers undertook a literature study to identify the nature, extent and effect of skills shortages in South Africa. They consulted a wide range of primary and secondary resources in order to acquire an in-depth understanding of the problem. The article explains the research approach and method comprehensively. It also outlines the research method the researchers used. Main findings: This study shows that several factors cause serious skills shortages in SA. Practical/managerial implications: The researchers mention only two significant implications. Firstly, this article provides a logical description of the nature, extent and effect of skills shortages on the economy. Secondly, it indicates clearly the implications of skills shortages for immigration policy. Contribution/value-add: This study confirms the findings of similar studies the Centre for Development and Enterprise (CDE conducted. Opening the doors to highly skilled immigrants can broaden the skills pool.

Pharmaceutical drug shortages (DSs) are a global problem which presents challenges to countries around the world. Shortages of pharmaceutical products may have a direct detrimental impact on public health and patients' wellbeing by causing delayed, or even lack of, treatment. Moreover, DSs may force both patients and caregivers to use unfamiliar drugs, which could lead to medication errors. The objective of our study was to analyze DSs in Israel during the years 2013-2015, assessing their etiology and exploring the steps taken for their mitigation and prevention. The database of the Israeli Ministry of Health (MoH) on drug shortages contains all the DSs recorded in Israel since 2013, detailing the cause of the DS, its duration, steps taken in its' management and the availability of generic or therapeutic alternatives. Selected examples of DSs from the database are described in this paper in order to identify the causes of DSs, the scope of the problem and possible solutions. Additionally, we have reviewed the recent activities performed by European Medicine Agency (EMA) and the American Food and Drug Administration (FDA) in their efforts to minimize this problem. Several factors contributing towards DSs in Israel were identified, including quality problems in both the final drug product and in the raw materials, upgrades and improvements of the manufacturing process required by the MoH, manufacturing by a sole supplier, dramatic price decrease in off-patent medications causing the manufacturer to discontinue the distribution of the product in Israel, just-in-time inventory control, and others. One of the most important steps in managing drug shortages was identified to be early notification of the shortage by the Marketing Authorization Holder (MAH) to the MoH. In 2013, the Israeli MoH updated the regulation on drug shortages instructing MAHs on their obligation of early notification to the MoH. Furthermore, various steps dealing with marketing withdrawal of drugs

Moore, S T

1990-01-01

A recent analysis of data from the Bureau of Labor statistics raise serious implications for the long-term care industry. The human resource problems faced by managers in long-term care will escalate into a fullblown crisis by the end of this century. This will result from a decrease in the number of young workers available to work in unskilled and semiskilled occupations. The effect of this shortage will be exaggerated by an expansion of other sectors of the service industry. Long-term care facilities will be forced to compete with the fast food and retail industry as well as other sectors of the health industry for scarce workers. This article briefly examines the causes, consequences of this problem and suggests several strategies to mitigate the effect of the coming labor shortage.

Glucocorticoid (GC) exposure increases food intake, but the mechanisms in humans are not known. Investigation of appetite and food craving has not been done in patients with chronic GC exposure due to Cushing's disease (CD), either before or after treatment, and could provide insight into mechanisms of food intake and obesity in these patients. To examine whether surgical remission of CD changes appetite (prospective consumption, hunger, satisfaction, and fullness) and food cravings (sweet, salty, fatty, and savory); and to identify predictors of appetite and craving in CD remission. 30 CD patients, mean age 40.0 years (range 17-70), mean BMI 32.3 ± 6.4, were prospectively studied before and at a mean of 17.4 mo. after remission. At each visit fasting and post-test meal (50% carbohydrate, 35% protein, 15% fat) appetite and craving scores were assessed. Remission decreased prospective consumption, sweet and savory craving (p appetite regulation due to abdominal fat mass and circulating cortisol could play a role in the cardiovascular and metabolic risk that has been reported in CD patients despite remission.

Background Unprecedented drug shortages announced by the US Food and Drug Administration (FDA) have severely affected therapeutic access, patient safety, and public health. With continued shortages, patients may seek drugs online. Objective To assess the prevalence of online marketing for current FDA shortage drugs and potential patient safety risks. Methods We performed a descriptive study of the prevalence of online marketing for shortage drugs—that is, offers for sale of each drug, including characteristics of online drug sellers and intermediary sites marketing these drugs. Results Of the 72 FDA shortage-listed drugs, 68 (94%) were offered for sale online. We found 291 offers for these drugs, the vast majority (n = 207, 71.1%) by online drug sellers selling direct to consumers. Intermediary sites included data aggregators (n = 22, 8%), forum links (n = 23, 8%), and personal page data links (n = 34, 12%), as well as Flickr social media links (n = 5, 2%), all advertising drugs without a prescription. Of the 91 online drug sellers identified, 31 (34%) had more than 1 shortage drug offered for sale, representing most (n = 148, 71%) of all online drug seller sales offers. The majority of these online drug sellers (n = 21, 68%) were on the National Association of Boards of Pharmacy (NABP) Not Recommended Sites list. Finally, for shortage drugs with an online drug seller (n = 58, 85%), 53 (91%) had at least one site on the Not Recommended list and 21 (36%) had only sites on the Not Recommended list. Conclusions FDA shortage drugs are widely marketed over the Internet. Suspect online drug sellers and intermediaries dominate these sales offers. As a critical risk management issue, patients, providers, and policymakers should be extremely cautious in procuring shortage drugs through Internet sourcing. PMID:22321731

Background: Patients with mental disorders, such as depression and anxiety, who seek medical care in private psychiatric clinics in Riyadh, Saudi Arabia, have recently expressed concerns to doctors about difficulty in filling psychotropic medications, such as Amitriptyline and Aripiprazole, at retail community pharmacies. Objectives: The aim of this study was to investigate whether there is a shortage of some commonly prescribed psychotropic medications in retail community pharmacies in Saudi Arabia, and if so, to explore the possible reasons behind the shortage of these medications. Methods: The availability of 28 commonly prescribed psychotropic medications was checked in multiple retail community pharmacies in 4 different regions of Saudi Arabia. Further, potential reasons behind the shortage of some psychotropic medications in retail community pharmacies were also explored. Results: Amitriptyline, Amoxapine, Aripiprazole, Bupropion, Buspirone, Duloxetine, Haloperidol, Hydroxyzine, Lithium, Prochlorperazine, Procyclidine, Promethazine, Thioridazine, Trazodone, and Trifluoperazine were unavailable in over half of the 248 community pharmacies surveyed. Four possible reasons behind the shortage of these medications were reported by 31 pharmacists working in different retail community pharmacies' purchasing departments, with a majority (58.06%) reporting the primary reason for a shortage of these medications that they are slow-moving items with low profit margins. Conclusions: The findings of this study should expedite the reform process in both the Ministry of Health and the Saudi Food and Drug Authority (SFDA) to publish and enforce an essential list of medications for retail community pharmacies, which should include the most commonly prescribed psychotropic medications.

Full Text Available Purpose: The purpose of this study is to identify effective strategies used by Alabama hospitals to manage drug shortages. Moreover, this study aims to determine if there are any relationships among hospital size, utilization of a standard policy for drug shortage management and perceived usefulness of standard procedures for drug shortages. Methods: A paper survey was mailed to 129 hospital pharmacies in Alabama (per the Alabama Hospital Association directory. The survey consisted of 5 demographic questions, questions involving perception of current medication shortages, sources of information about shorted drugs, and frequency of discussion at P&T committee meetings. Most importantly, the survey contained questions about the use of a standard policy for handling drug shortages, the effectiveness of the policy if one is used, and an open-ended question asking the recipient to describe the policy being used. Results: A response rate of 55% was achieved as 71 surveys were completed and returned. Approximately 70% of the survey respondents described the current drug shortage issue as a top priority in their pharmacy department. The pharmacy distributor served as the primary source of information regarding drug shortages for 45% of the facilities. There is a direct relationship between size of hospital and likelihood of utilization of a standard policy or procedure for drug shortage management among the sample. The smaller facilities of the sample perceived their management strategies as effective more frequently than the larger hospitals. Conclusion: Common components of effective management strategies included extensive communication of shortage details and the ability to locate alternative products. The use of portable technology (e.g., Smart phones and tablets along with mobile applications may emerge as popular means for communicating drug product shortage news and updates within a facility or healthcare system.

Seasonal blood shortages can be eliminated.

Gilcher, Ronald O; McCombs, Suzanne

2005-11-01

This review is designed to help readers understand seasonal blood shortages and provide solutions through the use of technology that can increase the number of red blood cell units collected and the use of recruitment and marketing initiatives that appeal to the increasingly diverse donor base. Seasonal shortages are, in reality, mostly shortages of group O red blood cells and occur most commonly during midsummer and early winter. The shortages occur primarily from increased use of group O red blood cells at times of decreased donor availability. While reducing the disproportionate use of red cells will help, blood centers can more quickly reduce the seasonal deficits by using automated red cell technology to collect double red blood cell units; targeted marketing programs to provide effective messages; seasonal advertising campaigns; and recognition, benefits, and incentives to enhance the donor motivation donation threshold. A multi-level approach to increasing blood donations at difficult times of the year can ensure that donations are increased at a time when regular donor availability is decreased. Seasonal blood shortages can be eliminated by understanding the nature of the shortages, why and when they occur, and using more sophisticated recruitment and marketing strategies as well as automated collection technologies to enhance the blood supply.

2015-12-01

Full Text Available Background: The role of wild foods in combating problems of food shortage is paramount. However, existing approaches to combat food insecurity shock have generally focused on reducing vulnerability via increasing productivity of domesticated foods. In contrast, approaches that enhance resilience mainly through wild food sources have been less focused. This study examined the contribution of wild foods to household resilience to food insecurity in the green famine belt of Ethiopia. Methods: A cross-sectional survey of 220 households was conducted using a structured questionnaire, key informant interviews, and semi-participant observations. Factor analysis was run using SPSS to analyze data. Correlation analysis was used to examine the direction and strength of association between wild foods and the income and food access (IFA, a latent proxy indicator of resilience. Cross-tabulation was also run to determine the proportion of households in each ethno-culture group under each resilience category. Results: The mean amount of wild foods obtained by households was 156.61 kg per household per annum. This was about 5 % and 9 % of, gross and, net food available from all sources respectively. Wild foods contributed well to household resilience as the factor loading (Factor2 = 0.467 was large enough and were significantly correlated with IFA (r = 0.174. Wild vegetables were the most collected and consumed type of wild foods constituting 52.4 % of total amount of wild foods. The total amount of wild foods was smaller than that of domesticated sources of food. The majority of households (38.6 % reported "reduced source of wild foods" as a reason for this. Smaller proportion of the indigenous (11.2 % than the non-indigenous (34.1 % ethno-culture group reported one or more reasons for their lower level of dependence on wild foods. Conclusion: From the study we concluded that wild foods had important contribution to households' resilience to food shortages and

Labour shortages are an increasing concern for companies in Alberta, where the economy is booming. This presentation provided statistics on labour shortages and Alberta's labour force. Between 1995 and 2004, employment in Alberta increased by more than 433,000 jobs, and is predicted to grow, but the natural population increase in the province is only 19,600 per year. It is expected that by 2010, immigrants will account for all growth in Canada's labour force. By 2020, an additional $100 billion of capital will be invested in Alberta, which is competing for labour with every other industrialized economy in the world. This presentation included a series of graphs and charts depicting Canada's national unemployment rate by province; Alberta's unemployment rate; oil sands capital expenditure; regional workforce requirements; and new jobs in the oil sands industry from 1998 to 2010. Employment requirements by trade were also highlighted along with projected labour shortages in 16 different trades. The author recommended that better long-term labour supply and demand models are needed along with rationalization and streamlining of credentials systems. Other solutions to labour shortages may include the removal of barriers to interprovincial and foreign workers; education and training; enhanced productivity; industry collaboration; and maximization of the labour pool to include women and Aboriginal workers. tabs., figs.

Trends in shortages of vaccines and immune globulin products from 2001 through 2015 in the United States are described. Drug shortage data from January 2001 through December 2015 were obtained from the University of Utah Drug Information Service. Shortage data for vaccines and immune globulins were analyzed, focusing on the type of product, reason for shortage, shortage duration, shortages requiring vaccine deferral, and whether the drug was a single-source product. Inclusion of the product into the pediatric vaccination schedule was also noted. Of the 2,080 reported drug shortages, 59 (2.8%) were for vaccines and immune globulin products. Of those, 2 shortages (3%) remained active at the end of the study period. The median shortage duration was 16.8 months. The most common products on shortage were viral vaccines (58%), especially hepatitis A, hepatitis B, rabies, and varicella vaccines (4 shortages each). A vaccine deferral was required for 21 shortages (36%), and single-source products were on shortage 30 times (51%). The most common reason for shortage was manufacturing problems (51%), followed by supply-and-demand issues (7%). Thirty shortages (51%) were for products on the pediatric schedule, with a median duration of 21.7 months. Drug shortages of vaccines and immune globulin products accounted for only 2.8% of reported drug shortages within a 15-year period, but about half of these shortages involved products on the pediatric vaccination schedule, which may have significant public health implications.

Protecting food security when facing uncertain climate: Opportunities for Afghan communities

Climate change, population growth, and weakly developed water management institutions in many of the world's dry communities have raised the importance of designing innovative water allocation methods that adapt to water supply fluctuations while respecting cultural sensitivities. For example, Afghanistan faces an ancient history of water supply fluctuations that have contributed to periodic food shortage and famine. Poorly designed and weakly enforced water allocation methods continue to result in agriculture sector underperformance and periodic food shortages when water shortfalls occur. To date, little research has examined alternative water sharing rules on a multi-basin scale to protect food security for a subsistence irrigation society when the community faces water shortage. This paper's contribution examines the economic performance of three water-sharing mechanisms for three basins in Afghanistan with the goal of protecting food security for crop irrigation under ongoing threats of drought, while meeting growing demands for food in the face of anticipated population growth. We achieved this by formulating an integrated empirical optimization model to identify water-sharing measures that minimize economic losses while protecting food security when water shortages occur. Findings show that implementation of either a water trading policy or a proportional shortage policy that respects cultural sensitivities has the potential to raise economic welfare in each basin. Such a policy can reduce food insecurity risks for all trading provinces within each basin, thus being a productive institution for adapting to water shortage when it occurs. Total economic welfare gains are highest when drought is the most severe for which suffering would otherwise be greatest. Gains would be considerably higher if water storage reservoirs were built to store wet year flows for use in dry years. Our results light a path for policy makers, donors, water administrators, and farm

Recent manufacturing problems resulted in a shortage of the only U.S.-licensed yellow fever vaccine. This shortage is expected to lead to a complete depletion of yellow fever vaccine available for the immunization of U.S. travelers by mid-2017. CDC, the Food and Drug Administration (FDA), and Sanofi Pasteur are collaborating to ensure a continuous yellow fever vaccine supply in the United States. As part of this collaboration, Sanofi Pasteur submitted an expanded access investigational new drug (eIND) application to FDA in September 2016 to allow for the importation and use of an alternative yellow fever vaccine manufactured by Sanofi Pasteur France, with safety and efficacy comparable to the U.S.-licensed vaccine; the eIND was accepted by FDA in October 2016. The implementation of this eIND protocol included developing a systematic process for selecting a limited number of clinic sites to provide the vaccine. CDC and Sanofi Pasteur will continue to communicate with the public and other stakeholders, and CDC will provide a list of locations that will be administering the replacement vaccine at a later date.

The effect of infant feeding practices on the development of food allergy remains controversial. We examined the relationship between timing and patterns of food introduction and sensitization to foods at age 1 year in the Canadian Healthy Infant Longitudinal Development (CHILD) birth cohort study. Nutrition questionnaire data prospectively collected at age 3, 6, 12, 18, and 24 months were used to determine timing of introduction of cow's milk products, egg, and peanut. At age 1 year, infants underwent skin prick testing to cow's milk, egg white, and peanut. Logistic regression models were fitted to assess the impact of timing of food exposures on sensitization outcomes, and latent class analysis was used to study patterns of food introduction within the cohort. Among 2124 children with sufficient data, delaying introduction of cow's milk products, egg, and peanut beyond the first year of life significantly increased the odds of sensitization to that food (cow's milk adjOR 3.69, 95% CI 1.37-9.08; egg adjOR 1.89, 95% CI 1.25-2.80; peanut adjOR 1.76, 95% CI 1.07-3.01). Latent class analysis produced a three-class model: early, usual, and delayed introduction. A pattern of delayed introduction, characterized by avoidance of egg and peanut during the first year of life, increased the odds of sensitization to any of the three tested foods (adjOR 1.78, 95% CI 1.26-2.49). Avoidance of potentially allergenic foods during the first year of life significantly increased the odds of sensitization to the corresponding foods. © 2017 The Authors.

Alterations in the intestinal microbiome are prospectively associated with the development of asthma; less is known regarding the role of microbiome alterations in food allergy development. Intestinal microbiome samples were collected at age 3-6 months in children participating in the follow-up phase of an interventional trial of high-dose vitamin D given during pregnancy. At age 3, sensitization to foods (milk, egg, peanut, soy, wheat, walnut) was assessed. Food allergy was defined as caretaker report of healthcare provider-diagnosed allergy to the above foods prior to age 3 with evidence of IgE sensitization. Analysis was performed using Phyloseq and DESeq2; P-values were adjusted for multiple comparisons. Complete data were available for 225 children; there were 87 cases of food sensitization and 14 cases of food allergy. Microbial diversity measures did not differ between food sensitization and food allergy cases and controls. The genera Haemophilus (log 2 fold change -2.15, P=.003), Dialister (log 2 fold change -2.22, P=.009), Dorea (log 2 fold change -1.65, P=.02), and Clostridium (log 2 fold change -1.47, P=.002) were underrepresented among subjects with food sensitization. The genera Citrobacter (log 2 fold change -3.41, P=.03), Oscillospira (log 2 fold change -2.80, P=.03), Lactococcus (log 2 fold change -3.19, P=.05), and Dorea (log 2 fold change -3.00, P=.05) were underrepresented among subjects with food allergy. The temporal association between bacterial colonization and food sensitization and allergy suggests that the microbiome may have a causal role in the development of food allergy. Our findings have therapeutic implications for the prevention and treatment of food allergy. © 2017 EAACI and John Wiley and Sons A/S. Published by John Wiley and Sons Ltd.

This article describes the shortage of generic injectable medications in Canada that affected hospitals in 2012. It traces the events leading up to the drug shortage, the causes of the shortage, and the responses by health administrators, pharmacists, and ethicists. The article argues that generic drug shortages are an ethical problem because health care organizations and governments have an obligation to avoid exposing patients to resource scarcity. The article also discusses some options governments could pursue in order to secure the drug supply and thereby fulfill their ethical obligations.

Soy and some of its constituents, such as isoflavones, have been shown to have cancer-inhibitory activities in experimental studies. Data from epidemiologic studies linking usual soy food intake with colorectal cancer are limited and inconsistent. The objective was to investigate whether soy food intake is associated with colorectal cancer risk. We prospectively examined 68,412 women aged 40-70 y and free of cancer and diabetes at enrollment. Usual soy food intake was assessed at baseline (1997-2000) and reassessed during the first follow-up (2000-2002) through in-person interviews with a validated food-frequency questionnaire. We excluded the first year of observation to minimize lifestyle changes related to preclinical disease. During a mean follow-up of 6.4 y, 321 incident colorectal cancer cases were identified. After adjustment for potential confounding factors, total soy food intake was inversely associated with colorectal cancer risk. Each 5-g/d increment in intake of soy foods as assessed by dry weight [equivalent to approximately 1 oz (28.35 g) tofu/d] was associated with an 8% reduction in risk (95% CI: 3%, 14%). Women in the highest tertile of intake had a multivariate relative risk of 0.67 (95% CI: 0.49, 0.90) compared with those in the lowest tertile (P for trend = 0.008). This inverse association was primarily confined to postmenopausal women. Similar results were also found for intakes of soy protein and isoflavones. This prospective study suggests that consumption of soy foods may reduce the risk of colorectal cancer in postmenopausal women.

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

Labour Shortages in Saskatchewan

Directory of Open Access Journals (Sweden)

J.C. Herbert Emery

2013-01-01

Full Text Available The predictions in the media and from think tanks sound altogether alarming: Saskatchewan, with its booming economy, could be facing a worker shortage so severe that it could drastically hobble the province’s ultimate economic potential. While the world craves only more of Saskatchewan’s abundant natural resources, the province won’t possibly be able to keep up, due to a scarcity of workers that could be as significant as one-fifth of the labour supply by 2020. The Saskatchewan government has rushed to analyze the predicament, issuing reports that urgently seek solutions. But it hasn’t really developed any solutions. In fact, it hasn’t done much about the supposedly looming crisis at all. And that, actually, might just be all it can — and should — do. In truth, Saskatchewan can’t be sure it will be facing a serious shortage, or any shortage, at all. And any attempt by the provincial government to substantially intervene in the labour market could cause more problems for employers and the economy, than it addresses. Saskatchewan’s labour market has already shown a remarkable ability to adjust, on its own, to the commodities boom, and what employers today call a shortage, could well just be everyone getting used to a much tighter, but still very functional, labour market. The province’s lack of action did mean it missed a once-in-a-lifetime opportunity to redirect a huge cohort of Gen-Y students into training for trades that are in high demand (that cohort is already in its mid-20s and finished, or finishing, its career training. That was a mistake. But one big thing the Saskatchewan government can still do to help employers — and workers — is to stop making the strains on labour worse by launching imminent public infrastructure projects that compete with the private sector for labour. Instead, the province should plan those for when the boom slows down and workers need the jobs. It should also abandon any ideas of ramping

Full text: A national project of food irradiation in the country is being proposed. At present there are no facilities for food irradiation (and food irradiation research) in Kenya. This report is therefore largely comparative between the traditional and the conventional food preservation methods on the one hand and the irradiation technique on the other. The report is also based on information from other countries where food irradiation is practiced (Kawabata, 1981) or is being also contemplated (Diop et al, 1997), as well as on the relevant report of the International Atomic Energy Agency (IAEA) on this topic (IAEA, 1993). The paper presents the statement of the research problem, i.e., in Kenya large quantities of food and other farm produces go to waste annually as a result of the inadequacies of the preservation techniques currently in use. These (other) preservation techniques, although often less controversial than the irradiation techniques, have also been found to be more expensive to run when compared to irradiation techniques. Such techniques, presently employed in Kenya, include the traditional methods (e.g. sun drying, smoke and fire drying, etc.) and modern techniques such as freezing or refrigeration, lyophilization, etc., as well as application of chemicals like insecticides and fumigants. The latter combines the disadvantages of high costs with environmental pollution and associated health risks. In this preliminary research, aimed at studying the prospects of a national food irradiation project, the following food items that are selected for their importance to the economy of the country, include potatoes, rice, maize, coffee, tea, various fruits, fish and meat. The paper also explores the economic feasibility as well as the human and technological requirements of establishing a commercial food irradiation plant, with aim of assessing the applicability of food irradiation as alternative or a complimentary approach for preservation technique in

Food availability after nuclear war

Cropper, W.P. Jr.; Harwell, M.A.

1985-01-01

The analysis of acute-phase food shortage vulnerabilities for 15 countries clearly indicates that in many countries massive levels of malnutrition and starvation are a possible outcome of a major nuclear war. The principal direct cause of such food shortages would be the climatic disturbances and societal disruptions during the initial post-war year. Even without climatic disturbances, import-dependent countries could suffer food shortages. Many of the countries with the highest levels of agricultural production and storage would probably be targets of nuclear weapons. It seems unlikely that food exports would continue from severely damaged countries, thus propagating effects to non-combatant countries. A similar analysis of food storage vulnerability in 130 countries indicates that a majority of people live in countries with inadequate food stores for such major perturbations. This is true even if consumption rates of 1,000 kcal . person/sup -1/ . day/sup -1/ are assumed rather than 1,500 kcal . person/sup -1/ . day/sup -1/. This vulnerability is particularly severe in Africa, and South America. Even though most of the countries of these continents have no nuclear weapons and are not likely to be targeted, the human consequences of a major nuclear war could be nearly as severe as in the principal combatant countries. Few countries would have sufficient food stores for their entire population and massive mortality would result if only pre-harvest levels were available. These conclusions represent an aspect of nuclear war that has only been recently realized. The possibility of climatic disturbances following a large nuclear war has introduced a new element to the global consequences expected. Not only are the populations of the major combatant countries at risk in a nuclear exchange, but also most of the global human population

Food shortage can drive body temperature regulation in wild heterothermic vertebrates

Vuarin, Pauline; Henry, Pierre-Yves

2014-01-01

Food availability is expected to trigger hibernation and torpor (ie heterothermy) use. Yet, laboratory experiments under controlled conditions dominate, and this hypothesis remains largely untested under natural conditions. Further experimental manipulations of food availability must therefore be conducted in the wild, accounting for other covarying environmental stressors.
What's the ROI for resolving the nursing faculty shortage?

Science.gov (United States)

Kowalski, Karren; Kelley, Brian M

2013-01-01

The nursing faculty shortage will have a fundamental impact on the ability to produce nurses. For most nursing schools and states, however, concerns about the relative merits of different solutions to the nursing faculty shortage are misplaced. Without significantly increased visibility and definition, accompanied by a clear public, private, and health care organization return on investment (ROI), proposing solutions to the nursing faculty shortage is at best premature and at worst irrelevant. There is simply too much competition for resources to expect that a vaguely defined and invisible problem with no rationale for increased investment will receive sufficient support from critical decision makers and constituencies. First must come problem definition, visibility, and ROI. Only then can the case be made for implementing solutions to the nursing faculty shortage.
Nursing shortages and international nurse migration.

Ross, S J; Polsky, D; Sochalski, J

2005-12-01

The United Kingdom and the United States are among several developed countries currently experiencing nursing shortages. While the USA has not yet implemented policies to encourage nurse immigration, nursing shortages will likely result in the growth of foreign nurse immigration to the USA. Understanding the factors that drive the migration of nurses is critical as the USA exerts more pull on the foreign nurse workforce. To predict the international migration of nurses to the UK using widely available data on country characteristics. The Nursing and Midwifery Council serves as the source of data on foreign nurse registrations in the UK between 1998 and 2002. We develop and test a regression model that predicts the number of foreign nurse registrants in the UK based on source country characteristics. We collect country-level data from sources such as the World Bank and the World Health Organization. The shortage of nurses in the UK has been accompanied by massive and disproportionate growth in the number of foreign nurses from poor countries. Low-income, English-speaking countries that engage in high levels of bilateral trade experience greater losses of nurses to the UK. Poor countries seeking economic growth through international trade expose themselves to the emigration of skilled labour. This tendency is currently exacerbated by nursing shortages in developed countries. Countries at risk for nurse emigration should adjust health sector planning to account for expected losses in personnel. Moreover, policy makers in host countries should address the impact of recruitment on source country health service delivery.
Strategies to address the nursing shortage in Saudi Arabia.

To investigate the nursing shortage in Saudi Arabia and specifically the shortage of Saudi nurses in the healthcare workforce and to propose solutions. Literature published from 1993 to 2013 providing relevant information on the nursing shortage, cultural traditions and beliefs, and nursing education and policies in Saudi was accessed from multiple sources including Medline, CINAHL Plus and Google Scholar and from official Saudi government document and was reviewed. Saudi Arabia depends largely on an expatriate workforce, and this applies to nursing. Saudi Arabia is experiencing a nursing shortage in common with most countries in the world and a shortage of Saudi nationals, especially women, in the healthcare workforce. The world shortage of nursing is extrinsic to Saudi, but intrinsic factors include a poor image of the nursing profession in the country that is exacerbated by cultural factors. With the call for the Saudization of the workforce to replace the imported workforce by Saudi nationals, including nurses, through the 1992 Royal Decree, Saudi Arabia faces a problem in attracting and retaining Saudi nationals in the nursing workforce. Solutions are suggested that are aimed at improving the public image of nursing through education and the use of the media and improvements in the workplace by addressing working processes such as teamwork, ensuring adequate staffing levels and addressing some aspects of culture which may make working in nursing more compatible with being a Saudi national. © 2016 International Council of Nurses.
Effective Factors on Shortage of Breastfeeding According to Iranian Traditional Medicine.

Support for breastfeeding is a public health priority. One of the major factors that can negatively affect breastfeeding is the lack of breast milk. There are many instructions on the subject of breast milk in Iranian traditional medicine resources. This article attempts to investigate causes and reasons for the lack of breast milk from the perspective of the great scholars in this field. This study reviews the literature based on the Iranian traditional medicine. The literature review included traditional medicine resources and a survey of reputable databases using keywords such as "morzae", "sady", "pestan", "sheer", "sheerkhar", and "hifzossehhe". The content analysis was used after collecting data. According to the viewpoint stated in traditional medicine literature, the primary substance for milk production is blood that transforms to milk after crossing the breast glandular tissue. The main causes of milk shortage can be classified into four categories, namely food-related factors, factors related to blood impaired, factors related to breast tissue and psychological and physical factors. One of the main reasons for milk shortage is the impaired quality and quantity of food. Appropriate mizaj of breast tissue is required for adequate milk production as it develops sufficient ability to absorb and transform the substance into milk. On the other hand, the ability of breast tissue is greatly influenced by the main organs of the body, particularly the heart; being the core of understanding psychological factors. Thus, psychological factors can have a significant effect on the process of milk production. Due to the importance of breastfeeding, reflection on other viewpoints, such as those mentioned in Iranian traditional medicine, could pave the way towards new research areas. It could also steer policies towards an extra focus on breastfeeding by mothers.
Food irradiation

International Nuclear Information System (INIS)

Beishon, J.

1991-01-01

Food irradiation has been the subject of concern and controversy for many years. The advantages of food irradiation include the reduction or elimination of dangerous bacterial organisms, the control of pests and insects which destroy certain foods, the extension of the shelf-life of many products, for example fruit, and its ability to treat products such as seafood which may be eaten raw. It can also replace existing methods of treatment which are believed to have hazardous side-effects. However, after examining the evidence produced by the proponents of food irradiation, the author questions whether it has any major contribution to make to the problems of foodborne diseases or world food shortages. More acceptable solutions, he suggests, may be found in educating food handlers to ensure that hygienic conditions prevail in the production, storage and serving of food. (author)

A critical review of the nursing shortage in Malaysia.

Science.gov (United States)

Barnett, T; Namasivayam, P; Narudin, D A A

2010-03-01

This paper describes and critically reviews steps taken to address the nursing workforce shortage in Malaysia. To address the shortage and to build health care capacity, Malaysia has more than doubled its nursing workforce over the past decade, primarily through an increase in the domestic supply of new graduates. Government reports, policy documents and ministerial statements were sourced from the Ministry of Health Malaysia website and reviewed and analysed in the context of the scholarly literature published about the health care workforce in Malaysia and more generally about the global nursing shortage. An escalation in student numbers and the unprecedented number of new graduates entering the workforce has been associated with other impacts that have been responded to symptomatically rather than through workplace reform. Whilst growing the domestic supply of nurses is a critical key strategy to address workforce shortages, steps should also be taken to address structural and other problems of the workplace to support both new graduates and the retention of more experienced staff. Nursing shortages should not be tackled by increasing the supply of new graduates alone. The creation of a safe and supportive work environment is important to the long-term success of current measures taken to grow the workforce and retain nurses within the Malaysian health care system.
Defining Primary Care Shortage Areas: Do GIS-based Measures Yield Different Results?

Daly, Michael R; Mellor, Jennifer M; Millones, Marco

2018-02-12

To examine whether geographic information systems (GIS)-based physician-to-population ratios (PPRs) yield determinations of geographic primary care shortage areas that differ from those based on bounded-area PPRs like those used in the Health Professional Shortage Area (HPSA) designation process. We used geocoded data on primary care physician (PCP) locations and census block population counts from 1 US state to construct 2 shortage area indicators. The first is a bounded-area shortage indicator defined without GIS methods; the second is a GIS-based measure that measures the populations' spatial proximity to PCP locations. We examined agreement and disagreement between bounded shortage areas and GIS-based shortage areas. Bounded shortage area indicators and GIS-based shortage area indicators agree for the census blocks where the vast majority of our study populations reside. Specifically, 95% and 98% of the populations in our full and urban samples, respectively, reside in census blocks where the 2 indicators agree. Although agreement is generally high in rural areas (ie, 87% of the rural population reside in census blocks where the 2 indicators agree), agreement is significantly lower compared to urban areas. One source of disagreement suggests that bounded-area measures may "overlook" some shortages in rural areas; however, other aspects of the HPSA designation process likely mitigate this concern. Another source of disagreement arises from the border-crossing problem, and it is more prevalent. The GIS-based PPRs we employed would yield shortage area determinations that are similar to those based on bounded-area PPRs defined for Primary Care Service Areas. Disagreement rates were lower than previous studies have found. © 2018 National Rural Health Association.

Tan, Yee Xi; Moles, Rebekah J; Chaar, Betty B

2016-10-01

Background Medicine shortages are an ongoing global problem. The Therapeutic Goods Administration (TGA) dedicated a website for monitoring of medicine shortages in Australia in May 2014, as part of the Medicine Shortage Information Initiative. This study aimed to explore the views of pharmacists regarding medicine shortages in the community setting and the impact of the TGA website in Australia. Setting Community pharmacies in New South Wales, Australia. Method Twenty semi-structured interviews were conducted with community pharmacists. Data collected were analysed thematically utilising the framework analysis method. Main outcome measure Qualitative analysis conducted using the framework approach. Results Findings clearly indicated that medicine shortages were experienced on a regular basis, but most participants were unaware of the TGA website. Medicine shortages reportedly impacted both pharmacists and consumers; and various workarounds were undertaken to manage the issue. The "price disclosure policy" was found to be a prominent contributing factor in emerging shortages. Suggestions were made for ways to improve the growing occurrence of shortages. Conclusion Overall, the study found that there was a lack of familiarity with the TGA website, despite experiencing regular shortages of medicines in practice. Also highlighted, was the importance of pharmacists prioritising patient care over business decisions. To reduce prescribing of out-of-stock medicines notifying doctors about shortages was also considered important, to allow for early action to be taken at higher levels of the supply chain. Findings of this study may help direct future policy-making around the world, as medicine shortages is a problem shared by healthcare providers in most countries around the world.

Drug supply shortages are common in health systems due to manufacturing and other delays. Frequently, shortages are successfully addressed through conservation and redistribution efforts, with limited impact on patient care. However, when Sandoz Canada Inc. announced in February 2012 that it was reducing production of a number of generic injectable drugs at its Quebec facility, the scope and magnitude of the drug supply shortage were unprecedented in Canada. The potential for an extreme scarcity of some drugs raised ethical concerns about patient care, including the need to limit access to some health services. In this article, the authors describe the development and implementation of an ethical framework to promote equitable access to drugs and healthcare services in the context of a drug supply shortage within and across health systems.

Organically produced foods are less likely than conventionally produced foods to contain pesticide residues. We examined the hypothesis that eating organic food may reduce the risk of soft tissue sarcoma, breast cancer, non-Hodgkin lymphoma and other common cancers in a large prospective study of 623 080 middle-aged UK women. Women reported their consumption of organic food and were followed for cancer incidence over the next 9.3 years. Cox regression models were used to estimate adjusted relative risks for cancer incidence by the reported frequency of consumption of organic foods. At baseline, 30%, 63% and 7% of women reported never, sometimes, or usually/always eating organic food, respectively. Consumption of organic food was not associated with a reduction in the incidence of all cancer (n=53 769 cases in total) (RR for usually/always vs never=1.03, 95% confidence interval (CI): 0.99-1.07), soft tissue sarcoma (RR=1.37, 95% CI: 0.82-2.27), or breast cancer (RR=1.09, 95% CI: 1.02-1.15), but was associated for non-Hodgkin lymphoma (RR=0.79, 95% CI: 0.65-0.96). In this large prospective study there was little or no decrease in the incidence of cancer associated with consumption of organic food, except possibly for non-Hodgkin lymphoma.

In light of the continuing rise in food prices during and after the 2008 world food crisis, whether food and cash transfers are equally effective in improving food security and diet quality is debatable. To compare the effects of conditional food and cash transfers of the Ethiopian Productive Safety Net Program (PSNP) on household food security and dietary diversity. Data on household dietary diversity, child anthropometry, food security, and preference of transfer modalities (food, cash, or mixed) were generated from a cross-sectional survey of 195 PSNP beneficiary households (67 receiving food and 128 receiving cash) in Hawella Tulla District, Sidama, southern Ethiopia. Most beneficiaries (96%) reported food shortages, and 47% reported food shortages that exceeded 3 months. Households receiving cash had better household dietary diversity scores (p = .02) and higher consumption of oils and fats (p = .003) and vitamin A-rich foods (p = .002). Compared with households receiving food, households receiving cash were more affected by increases in food prices that forced them to reduce their number of daily meals (p diversity than households receiving food, a result suggesting that cash transfers may be more effective. However, the continuing rise infood prices may offset these benefits unless cash transfers are index-linked to food price fluctuations.

Food shortages and gender relations in Ikafe settlement, Uganda.

Science.gov (United States)

Payne, L

1998-03-01

In 1996, an 18-month-old settlement created for 55,000 Sudanese refugees in northern Uganda came under attack by Ugandan rebels. By March 1997, the entire population of the settlement had migrated in search of safety. Because the refugees lost their livelihoods and cultivated fields, they had to adopt short-term coping strategies to acquire food. Two Oxfam researchers gathering information during this period for use in program planning and monitoring found that coping strategies included 1) hazarding dangerous journeys (women risked rape or abduction; men risked beating, looting, killing, or abduction) to harvest crops; 2) seeking piece-work employment; 3) exchanging sex for food; and 4) depleting assets. The crisis was particularly severe for single people (especially those with children). In families where the women but not the men could find employment, some men took on household responsibilities. As malnutrition increased, health declined. Observed changes to household gender relations included new sexual divisions of labor, assumption by females of decision-making power, increased domestic quarreling, and marital break-down (especially in cases where women had been raped). On the community level, women assumed more responsibility as men withdrew socially or left the settlement. These findings point to the importance of providing refugees with seeds, with small loans to stimulate business, and with the means to rebuild their sense of community.

An analysis of news flow on the nation's nurse shortage.

Science.gov (United States)

Kalisch, B J; Kalisch, P A; Clinton, J

1981-09-01

Using data from national newspaper clipping services, this article analyzes characteristics of 1978 news coverage of the nation's nurse shortage. Based on a content analysis of nearly 3,000 newspaper articles, findings revealed that 14 per cent of the articles mentioned problems of nurse supply. Articles on nurse shortage were most frequent in the Pacific, Mid-Atlantic and South-Atlantic states and occurred least in the West-North Central and East-South Central states. Articles mentioning nurse shortage were more frequently placed on page 1, associated with clinical nursing in hospital settings and explained as the result of maldistribution of nurses, poor salaries, deficient working conditions and lack of job satisfaction. The reading public was confronted with three major consequences of current and continued shortages in nursing: 1) decline in the availability and diversity of health services; 2) erosion in the quality of care offered the public and jeopardized patient welfare; and 3) escalating health care costs. Solutions to the nurse shortage appear to be closely tied to further expansion of the issue among the public, the initiation of remedial governmental action and timely relocation of scarce resources within the health care industry.
Administration of the natural gas shortage in the USA

Energy Technology Data Exchange (ETDEWEB)

Pluge, W [Koeln Univ. (Germany, F.R.). Inst. fuer Energiewirtschaft

1978-05-01

The natural gas deficit is basically a consequence of the price policy of the U.S. government which keeps the prices of natural gas transported from one state to another subject to a maximum-price regulation. In the course of this development, the U.S. natural gas market has been characterized by three different types of shortage since the early seventies. There are regional differences in the administration of the shortage. Compared to the alternatives the rationing plan of the Federal Energy Regulatory Commission (FERC) is the best solution from on overall economic point of view, but it is rather impracticable and hard to put through completely. Natural gas rationing in the USA did not prevent temporary production losses and unemployment due to shortage. If the maximum-price regulation policy for natural gas is continued, the supply deficit for this energy carrier will become even greater. If, as the National Energy Plan proposes, the maximum-price regulation for natural gas would also pertain to the intrastate market in the future, natural gas shortages would occur there, too.

To assess the prospective associations between consumption of ultra-processed food and risk of cancer. Population based cohort study. 104 980 participants aged at least 18 years (median age 42.8 years) from the French NutriNet-Santé cohort (2009-17). Dietary intakes were collected using repeated 24 hour dietary records, designed to register participants' usual consumption for 3300 different food items. These were categorised according to their degree of processing by the NOVA classification. Associations between ultra-processed food intake and risk of overall, breast, prostate, and colorectal cancer assessed by multivariable Cox proportional hazard models adjusted for known risk factors. Ultra-processed food intake was associated with higher overall cancer risk (n=2228 cases; hazard ratio for a 10% increment in the proportion of ultra-processed food in the diet 1.12 (95% confidence interval 1.06 to 1.18); P for trendcancer risk (n=739 cases; hazard ratio 1.11 (1.02 to 1.22); P for trend=0.02). These results remained statistically significant after adjustment for several markers of the nutritional quality of the diet (lipid, sodium, and carbohydrate intakes and/or a Western pattern derived by principal component analysis). In this large prospective study, a 10% increase in the proportion of ultra-processed foods in the diet was associated with a significant increase of greater than 10% in risks of overall and breast cancer. Further studies are needed to better understand the relative effect of the various dimensions of processing (nutritional composition, food additives, contact materials, and neoformed contaminants) in these associations.

Can alternative sugar sources buffer pollinators from nectar shortages?

Gardner-Gee, Robin; Dhami, Manpreet K; Paulin, Katherine J; Beggs, Jacqueline R

2014-12-01

Honeydew is abundant in many ecosystems and may provide an alternative food source (a buffer) for pollinators during periods of food shortage, but the impact of honeydew on pollination systems has received little attention to date. In New Zealand, kānuka trees (Myrtaceae: Kunzea ericoides (A. Rich) Joy Thompson) are often heavily infested by the endemic honeydew-producing scale insect Coelostomidia wairoensis (Maskell) (Hemiptera: Coelostomidiidae) and the period of high honeydew production can overlap with kānuka flowering. In this study, we quantified the sugar resources (honeydew and nectar) available on kānuka and recorded nocturnal insect activity on infested and uninfested kānuka during the flowering period. Insects were abundant on infested trees, but flowers on infested trees received fewer insect visitors than flowers on uninfested trees. There was little evidence that insects had switched directly from nectar-feeding to honeydew-feeding, but it is possible that some omnivores (e.g., cockroaches) were distracted by the other honeydew-associated resources on infested branches (e.g., sooty molds, prey). Additional sampling was carried out after kānuka flowering had finished to determine honeydew usage in the absence of adjacent nectar resources. Moths, which had fed almost exclusively on nectar earlier, were recorded feeding extensively on honeydew after flowering had ceased; hence, honeydew may provide an additional food source for potential pollinators. Our results show that honeydew resources can impact floral visitation patterns and suggest that future pollinator studies should consider the full range of sugar resources present in the study environment.

The shortage of clinical preceptors compromises the current and future supply of healthcare providers and patient access to primary care. This article describes how an interprofessional coalition in South Carolina formed and sought government support to address the preceptor shortage. Some states have legislated preceptor tax credits and/or deductions to support the clinical education of future primary care healthcare providers. As a result of the coalition's work, a bill to establish similar incentives is pending in the South Carolina legislature.

Inappropriate dietary eliminations may impair quality of life, affect children's growth and unnecessarily impact on healthcare costs. Previous retrospective studies reported that around 25% of children continue a food-avoidance diet despite a negative oral food challenge (OFC). A definite pattern has not been found yet for patients not reintroducing the food. This study aimed to examine the role of child's nutritional attitudes and maternal anxiety in reintroducing food after a negative OFC. A prospective study was conducted involving 81 mothers of children with IgE-mediated food allergy. They completed a survey on nutritional behaviour and attitudes and the State-Trait Anxiety Inventory on the day of OFC and 6 months later. In total, 11.1% of children never or rarely ate the food after a negative OFC. Consumption of the reintroduced food is positively correlated to child's interest in tasting new foods before and after OFC and to changes in child's nutritional habits after OFC. It is negatively correlated to monotony of the diet after OFC. No correlations were found with other participants' characteristics or maternal anxiety. State anxiety significantly decreased after the OFC. A correlation was found between trait and state anxiety and the degree of change in nutritional habits after OFC. Evaluating child's approach towards food before the OFC is a promising approach to identify patients at risk of food reintroduction failure. Furthermore, it underlined the importance of reassessing food consumption in all patients after a negative OFC and supporting patients in the reintroduction of food. © 2016 John Wiley & Sons A/S.

Extent and effects of recurrent shortages of purified-protein derivative tuberculin skin test antigen solutions - United States, 2013.

Science.gov (United States)

2013-12-13

Two purified-protein derivative (PPD) tuberculin skin test (TST) antigen solutions are approved by the U.S. Food and Drug Administration (FDA): Tubersol (Sanofi Pasteur Limited) and Aplisol (JHP Pharmaceuticals, LLC). Tubersol was out of production in late 2012 through April 2013. Shortages of Aplisol have resulted from increased demand as practitioners have sought a substitute for Tubersol. Tubersol production resumed in May 2013, and supplies had been nearly restored by early June. However, in mid-July, state tuberculosis (TB) control officials notified CDC of difficulty obtaining Tubersol and Aplisol. Sanofi Pasteur notified FDA of a temporary delay in the availability of tuberculin in the 10-dose and 50-dose presentations. In mid-October, the 10-dose presentation was being returned to market, on allocation, which means that historical purchasing practices determine the amount that customers are allotted. In late October, the 50-dose presentation was being returned to market, also on allocation, one vial per historical customer per month. Supplies are forecast to approach normal during January 2014, after distributors have restored their supply chains. A compensatory surge in testing after deferment of testing during the periods of shortage might cause further temporary instability of supplies. In mid-August 2013, officials in 29 of 52 U.S. jurisdictions noted a shortage of at least one PPD TST antigen solution in health departments to the extent that it interrupted activities. This report includes a summary of the extent and effects of the shortages and a reiteration of advice on how to adapt to them.

The future of the nurse shortage: will wage increases close the gap?

Science.gov (United States)

Spetz, Joanne; Given, Ruth

2003-01-01

In recent years the U.S. media have been reporting a shortage of registered nurses (RNs). In theory, labor-market shortages are self-correcting; wage increases will bring labor markets into equilibrium, and policy intervention is not necessary. In this paper we develop a simple forecasting model and ask the question: How high must RN wages rise in the future to end the RN shortage? We find that inflation-adjusted wages must increase 3.2-3.8 percent per year between 2002 and 2016, with wages cumulatively rising up to 69 percent, to end the shortage. Total RN expenditures would more than double by 2016.

This article reports findings of a project funded by the Australian National Council for Vocational Education Research. The project explores solutions to current and projected skills shortages within the health and community services sector, from a vocational education and training perspective. Its purpose is to locate, analyse and disseminate information about innovative models of health training and service delivery that have been developed in response to skill shortages. The article begins with a brief overview of Australian statistics and literature on the structure of the national health workforce and perceived skill shortages. The impact of location (state and rurality), demographics of the workforce, and other relevant factors, on health skill shortages is examined. Drawing on a synthesis of the Australian and international literature on innovative and effective models for addressing health skill shortages and nominations by key stakeholders within the health sector, over 70 models were identified. The models represent a mixture of innovative service delivery models and training solutions from Australia, as well as international examples that could be transposed to the Australian context. They include the skill ecosystem approach facilitated by the Australian National Training Authority Skill Ecosystem Project. Models were selected to represent diversity in terms of the nature of skill shortage addressed, barriers overcome in development of the model, healthcare specialisations, and different customer groups. Key barriers to the development of innovative solutions to skills shortages identified were: policy that is not sufficiently flexible to accommodate changing workplace needs; unwillingness to risk take in order to develop new models; delays in gaining endorsement/accreditation; current vocational education and training (VET) monitoring and reporting systems; issues related to working in partnership, including different cultures, ways of operating

Does dairy food intake predict arterial stiffness and blood pressure in men?: Evidence from the Caerphilly Prospective Study.

Arterial stiffness is an independent predictor of cardiovascular disease events and mortality, and like blood pressure, may be influenced by dairy food intake. Few studies have investigated the effects of consumption of these foods on prospective measures of arterial stiffness. The present analysis aimed to investigate the prospective relationship between milk, cheese, cream, and butter consumption and aortic pulse wave velocity, augmentation index, systolic and diastolic blood pressure, as well as cross-sectional relationships between these foods and systolic and diastolic blood pressure and metabolic markers using data from the Caerphilly Prospective Study. Included in this cohort were 2512 men, aged 45 to 59 years, who were followed up at 5-year intervals for a mean of 22.8 years (number follow-up 787). Augmentation index was 1.8% lower in subjects in the highest quartiles of dairy product intake compared with the lowest (P trend=0.021), whereas in the highest group of milk consumption systolic blood pressure was 10.4 mm Hg lower (P trend=0.033) than in nonmilk consumers after a 22.8-year follow-up. Cross-sectional analyses indicated that across increasing quartiles of butter intake, insulin (P trend=0.011), triacylglycerol (P trend=0.023), total cholesterol (P trend=0.002), and diastolic blood pressure (P trend=0.027) were higher. Across increasing groups of milk intake and quartiles of dairy product intake, glucose (P trend=0.032) and triglyceride concentrations (P trend=0.031) were lower, respectively. The present results confirm that consumption of milk predicts prospective blood pressure, whereas dairy product consumption, excluding butter, is not detrimental to arterial stiffness and metabolic markers. Further research is needed to better understand the mechanisms that underpin these relationships.

Liu, Jenny X; Kinfu, Yohannes; Dal Poz, Mario R

2008-01-01

Abstract Objective Global achievements in health may be limited by critical shortages of health-care workers. To help guide workforce policy, we estimate the future demand for, need for and supply of physicians, by WHO region, to determine where likely shortages will occur by 2015, the target date of the Millennium Development Goals. Methods Using World Bank and WHO data on physicians per capita from 1980 to 2001 for 158 countries, we employ two modelling approaches for estimating the future global requirement for physicians. A needs-based model determines the number of physicians per capita required to achieve 80% coverage of live births by a skilled health-care attendant. In contrast, our economic model identifies the number of physicians per capita that are likely to be demanded, given each country’s economic growth. These estimates are compared to the future supply of physicians projected by extrapolating the historical rate of increase in physicians per capita for each country. Findings By 2015, the global supply of physicians appears to be in balance with projected economic demand. Because our measure of need reflects the minimum level of workforce density required to provide a basic health service that is met in all but the least developed countries, the needs-based estimates predict a global surplus of physicians. However, on a regional basis, both models predict shortages for many countries in the WHO African Region in 2015, with some countries experiencing a needs-based shortage, a demand-based shortage, or both. Conclusion The type of policy intervention needed to alleviate projected shortages, such as increasing health-care training or adopting measures to discourage migration, depends on the type of shortage projected.

Looming labour shortages challenge Alberta resource industries

Energy Technology Data Exchange (ETDEWEB)

Simpson, R.

2005-07-01

The shortage of skilled manpower that is threatening the viability of Alberta's resource industry is discussed. According to statistics compiled by the Canadian Resource Development the Canadian labour force grew by about 226,000 per year during the last quarter century; this will be reduced by about 125,000 per year during the current decade. It is forecast that by 2016, the annul growth will be near zero. To make up for this unprecedented shortfall, the annual rate of immigration required would have to be as high as 650,000 per year. The Alberta Chamber's Workforce Development Committee is aware of the urgency of the situation and is attempting to aggressively investigate the causes of the shortage of skilled labour and finding ways to deal with the problem. Current investigation appears to point the finger at the state of post-secondary education, most particularly the significantly higher underemployment among aboriginal youth and the likelihood that skills programs training developed to encourage First Nation's people would be the most effective way to help easing the growing labour shortage. Too few educational placement for students, a lack of adequate training equipment and financial resources in post-secondary institutions, and the variations in the quality of provincial educational standards receive the most blame, combined with a lack of awareness of employment opportunities or training programs, and the inability to migrate to high opportunity employment areas. A notable program addressing this issue is the Alberta Apprenticeship and Industry Training System which helps young people to start their apprenticeship training while still in high school, and encourage them to continue their training after graduation from high school. The federal government and other groups also encourage participation among Ab originals and work towards eliminating some of the underlying factors of labour shortages, including cultural biases, barriers to inter
The nurse manager: job satisfaction, the nursing shortage and retention.

2005-07-01

A critical shortage of registered nurses exists in the United States and this shortage is expected to worsen. It is predicted that unless this issue is resolved, the demand for nursing services will exceed the supply by nearly 30% in 2020. Extensive analysis of this pending crisis has resulted in numerous recommendations to improve both recruitment and retention. The purpose of this article is to clearly outline the issues contributing to this problem, and to provide the nurse manager with information regarding specific influences on job satisfaction as it relates to job turnover and employee retention. To accomplish this, an analysis of the literature using both national and international sources is used to formulate the lessons learned as well as strategies and future courses of action designed to address this shortage.

Prospects of international trade in irradiated foods

International Nuclear Information System (INIS)

Loaharanu, P.

1990-01-01

Irradiation is gaining recognition as a physical process for reducing food losses, enhancing hygienic quality of food and facilitating food trade. At present, 36 countries have approved the use of irradiation for processing collectively over 40 food items either on an unconditional or restricted basis. Commercial use of irradiated foods and food ingredients is being carried out in 22 countries. Technology transfer on food irradiation is being intensified to local industry in different regions. Worldwide, a total of 40 commercial/demonstration irradiators available for treating foods have been or are being constructed. Acceptance and control of international trade in irradiated foods were discussed at the International Conference on the Acceptance, Control of and Trade in Irradiated Food, jointly convened by FAO, IAEA, WHO and ITC-UNCTAD/GATT in Geneva, Switzerland, 12-16 December 1988. An ''International Document on Food Irradiation'' was adopted by consensus at this Conference which will facilitate wider acceptance and control of international trade in irradiated foods. (author)

Weng, Ke-Gui; Yuan, Ya-Ling

2017-08-01

Epidemiological studies were inconsistent on the association between soy food intake and risk of gastric cancer (GC). This study aimed to determine the role of soy food intake in the development of GC.A systematic search was conducted in PubMed and Web of Science to identify all relevant studies. Study-specific relative risks (RRs) and 95% confidence intervals (CIs) were pooled using a random-effects model, and the dose-response relationship between soy food intake and GC risk was also assessed.Thirteen prospective studies were identified with a total of 517,106 participants and 5800 cases. Among 11 types of soy food, high intake of total soy food (the highest vs the lowest category: RR: 0.78, 95% CI: 0.62-0.98) and nonfermented soy food (RR: 0.63, 95% CI: 0.50-0.79) were inversely associated with GC risk, while high intake of miso soup was associated with the risk in male (RR: 1.17, 95% CI: 1.02-1.36). In dose-response meta-analysis, total soy food intake (0-150 g/day) showed no significant association with GC risk, while high intake of nonfermented soy food was inversely related, especially an intake of more than 100 g/day. In male, miso soup intake (1-5 cups/day) was significantly associated with GC risk.High intake of nonfermented soy food might reduce the risk of GC, while miso soup intake might increase the risk in male.

New Jersey's natural gas shortage: a policy analysis

Energy Technology Data Exchange (ETDEWEB)

Cecil, J.L.; Morell, D.

1976-12-01

The public policy problems associated with New Jersey's natural gas shortage are extremely complex and rather difficult to examine. They involve a blend of technology, politics and economics; of regulatory mandates and profit-motivated initiatives; of Federal and state interaction and conflict. To understand the state's gas shortage and to lay the basis for recommending measures to deal with it, information about the basic technology, the organization of the gas industry, the national regulatory posture, and the possible causes of the gas shortage encompasses Part I of the overall study. In Part II, the analysis turns from the national level to a direct examination of New Jersey's gas situation. In Part III, Chapter VIII, the following are considered: the state's supply of natural gas, distribution of these supply volumes within New Jersey by the four major gas utilities, and gas consumption patterns within the state as a whole and then for each major consuming sector (electric utility, industrial, commercial, and residential). This chapter concludes with an analysis of the impacts of the gas shortage to date in New Jersey, and of its probable effects in the near-term. In the final chapter, some tentative conclusions and broad suggestions are advanced for public policies to mitigate the gravity of the state's position with respect to natural gas. Analysis proceeds, in turn, through consideration of possible state actions in several areas: increasing total interstate gas supplies; increasing New Jersey's share of whatever national total exists; making greater (or more effective) use of alternate fuels; and moderating demand for gas through aggressive conservation policies. Some short-term measures to cope better with whatever level of gas shortage exists in the state at any particular time are suggested. 151 references. (MCW)

Parallels exist in the comparing categories work contents, working structure, income and social status, medical school formation, private life, psychological motives. Differences are found in the categories biography and social selection, medical socialisation, residency. In Switzerland, residency is not uniformly structured, rarely institutionally organised and contains only few elements specific to general medicine. In France, medical socialisation not only exalts the specialists, but also strongly devaluates the GPs. By systematic analysis and comparison of both countries' pertinent literature, France and Switzerland can deepen their understanding of GP shortage. This paper identifies possible fields of action from medical school through residency up to workplace conditions that are pivotal in addressing the shortage of GPs.

Full Text Available Abstract Background Few data are available to guide programmatic solutions to the overlapping problems of undernutrition and HIV infection. We evaluated the impact of food assistance on patient outcomes in a comprehensive HIV program in central Haiti in a prospective observational cohort study. Methods Adults with HIV infection were eligible for monthly food rations if they had any one of: tuberculosis, body mass index (BMI 2, CD4 cell count 3 (in the prior 3 months or severe socio-economic conditions. A total of 600 individuals (300 eligible and 300 ineligible for food assistance were interviewed before rations were distributed, at 6 months and at 12 months. Data collected included demographics, BMI and food insecurity score (range 0 - 20. Results At 6- and 12-month time-points, 488 and 340 subjects were eligible for analysis. Multivariable analysis demonstrated that at 6 months, food security significantly improved in those who received food assistance versus who did not (-3.55 vs -0.16; P Conclusions Food assistance was associated with improved food security, increased BMI, and improved adherence to clinic visits at 6 and 12 months among people living with HIV in Haiti and should be part of routine care where HIV and food insecurity overlap.

The aim was to determine how a shortage of physicians at Finnish health centres has affected the job satisfaction of the entire staff. A questionnaire was posted to 2848 employees working with patients at health centres in the Finnish provinces of Satakunta and Varsinais-Suomi. The information concerning the shortage of physicians at health centres was taken from research undertaken by the Finnish Medical Association in October 2003. The health centres were divided into four groups according to the severity of the shortage. The questionnaire was returned by 1447 employees. The staff at health centres with the most severe shortage of physicians were less satisfied with the management of the organization. Employees at health centres with a minor shortage of physicians were more satisfied with the quality of services in their operational unit. The shortage of physicians had no impact on staff satisfaction regarding the operation of their work unit, the strain of dealing with issues within their work environment, feelings of stress, the strain of working under pressure that they experienced, or interest in finding a new job. The majority of healthcare employees are satisfied and motivated in their work. The shortage of physicians has only a slightly negative impact on their satisfaction.

Drug shortages were a complex global problem. The aim of this study was to analyze, characterize, and assess the drug shortages, and identify possible solutions in Shaanxi Province, western China. A qualitative methodological approach was conducted during May-June 2015 and December 2015-January 2016. Semi-structured interviews were performed to gather information from representatives of hospital pharmacists, wholesalers, pharmaceutical producers, and local health authorities. Thirty participants took part in the study. Eight traditional Chinese medicines and 87 types of biologicals and chemicals were reported to be in short supply. Most were essential medicines. Five main determinants of drug shortages were detected: too low prices, too low market demands, Good Manufacturing Practice (GMP) issues, materials issues, and approval issues for imported drugs. Five different solutions were proposed by the participants: 1) let the market decide the drug price; 2) establish an information platform; 3) establish a reserve system; 4) enhance the communication among the three parties in the supply chain; and 5) improve hospital inventory management. Western China was currently experiencing a serious drug shortage. Numerous reasons for the shortage were identified. Most drug shortages in China were currently because of "too low prices." To solve this problem, all of the stakeholders, especially the government, needed to participate in managing the drug shortages.

2012-01-01

The consequence of short-time energy shortage under extreme conditions, such as earthquake, tsunami, and hurricane, may cause local areas to suffer from delayed rescues, widespread power outages, tremendous economic losses, and even public safety threats. In such urgent events of local energy shortage, agile energy dispatching through an effective energy transportation network, targeting the minimum energy recovery time, should be a top priority. In this paper, a novel methodology is developed for energy network dispatch optimization under emergency of local energy shortage, which includes four stages of work. First, emergency-area-centered energy network needs to be characterized, where the capacity, quantity, and availability of various energy sources are determined. Second, the energy initial situation under emergency conditions needs to be identified. Then, the energy dispatch optimization is conducted based on a developed MILP (mixed-integer linear programming) model in the third stage. Finally, the sensitivity of the minimum dispatch time with respect to uncertainty parameters is characterized by partitioning the entire space of uncertainty parameters into multiple subspaces. The efficacy of the developed methodology is demonstrated via a case study with in-depth discussions. -- Highlights: ► Address the energy network dispatch problem under emergency of local energy shortage. ► Minimize the energy restoration time for the entire energy network under emergency events. ► Develop a new MILP model and a sensitivity analysis method with respect to uncertainties.

This paper reviews researches, commentaries, and conference and public records of food irradiation, published mainly during the period 1987-1989, focusing on the current conditions of food irradiation that may pose not only scientific or technologic problems but also political issues or consumerism. Approximately 50 kinds of food, although not enough to fill economic benefit, are now permitted for food irradiation in the world. Consumerism is pointed out as the major factor that precludes the feasibility of food irradiation in the world. In the United States, irradiation is feasible only for spices. Food irradiation has already been feasible in France, Hollands, Belgium, and the Soviet Union; has under consideration in the Great Britain, and has been rejected in the West Germany. Although the feasibility of food irradiation is projected to increase gradually in the future, commercial success or failure depends on the final selection of consumers. In this respect, the role of education and public information are stressed. Meat radicidation and recent progress in the method for detecting irradiated food are referred to. (N.K.) 128 refs.

Recurrent aphthous stomatitis (RAS) is a common disease of the oral mucosa with an unknown etiology. This study aimed to determine if food additives play a role in the etiology of RAS as well as to determine if patch testing can be used to detect which allergens cause RAS. This prospective study included 24 patients with RAS and 22 healthy controls. All the participants underwent patch testing for 23 food additives. In total, 21 (87.5%) RAS patients and 3 (13.6%) controls had positive patch test reactions to ≥1 allergens; the difference in the patch test positivity rate between groups was significant (P food additives might play a role in the etiology of RAS and that patch testing could be a method for determining the etiology of RAS. © 2016 The International Society of Dermatology.
Association between shortage of energy supply and nuclear gene mutations leading to carcinomatous transformation.

Science.gov (United States)

DU, Jianping

Anaerobic bacteria use glycolysis, an oxygen-independent metabolic pathway, whereas energy metabolism in the evolved eukaryotic cell is performed via oxidative phosphorylation, with all eukaryotic cell activities depending upon high energy consumption. However, in cancer cells evolving from eukaryotic cells, the energy metabolism switches from oxidative phosphorylation to glycolysis. The shortage of energy supply induces cancer cells to acquire specific characteristics. Base pair renewal is the most energy-consuming process in the cell, and shortage of energy supply may lead to errors in this process; the more prominent the shortage in energy supply, the more errors are likely to occur in base pair renewal, resulting in gene mutations and expression of cancer cell characteristics. Thus, shortage of energy supply is associated with carcinomatous transformation.

Research and development work in food irradiation over the past several years has been essentially directed towads answering all possible questions in respect of the suitability of the process, quality of materials and safety for human use. A major effort was indeed, around the toxicological evaluation, till it was recognised internationally that irradiated items of food do not present any health hazards. This recognition along with the awareness of the hazards in the use of chemicals has resulted in a renewed interest in the use of radiations for preservation of food. Radiation preservation of food would reach the stage of practical application with additional information on design and functional aspects of radiation sources, appropriate for specific commodities. Each items has a particular dose requirement depending on the purpose of irradiation and the type of handling. 21 refs. (author)
Urban food self-reliance: significance and prospects.

Science.gov (United States)

Mougeot, L J

1993-10-01

This news account provides coverage of the satisfaction of urban food needs when retail costs are prohibitively high in developing countries. This account reports that 50-80% of average income is spent on food in nearly 50% of developing country's largest cities. Surveys conducted during the late 1980s confirm a range of 60-80% of income for expenditures on food. Surveys reveal that urban food costs are 10-30% higher than costs for rural dwellers. Urban household food production is a practice that has been around since the times of the Aztecs, the Incas, and Mayan cities. Reports survive of the Javanese and city dwellers along the Tigris and Euphrates producing their own food. Asian policy makers promote urban food production as critical to urban survival. Other factors influence urban food production. These factors include rapid urbanization, ineffective agricultural policies, inadequate food distribution systems, withdrawal of subsidies, reduction of wages, inflation, unemployment, lax urban regulations, civil strife, and drought. Government agencies are sometimes obstacles in outlawing the practice. Recent support for urban agriculture includes ten Asian, six African, and six Latin American countries. The number of urban farm workers is reported as 200 million worldwide. 700 million receive the benefits of urban agriculture. 25% of urban households in the US were engaged in urban food production during the 1980s. Better information, such as in comparative and longitudinal studies, is needed on urban poverty and the links between nutrition, income, employment, waste, and environmental issues. If cost-benefit analysis research finds a positive impact, then urban planners may need to incorporate city farming into conventional land use. The value of city farming needs to be assessed. Street food vending is an important source of income, particularly for women. Urban farming requires efficiency of space and knowledge of advances in technology and planning.

The nursing shortage in the United States is at a crisis level characterized by critical shortages of highly trained nurses and of nursing faculty. Key issues in addressing these shortages include awareness and image-building, along with enhanced outreach programs. Although these issues are related to marketing theory, most studies in this area are based on a vocational choice model. This study was grounded in marketing theory and the results offer a new perspective for addressing the nursing shortage. In-depth interviews conducted with 31 first-year nursing students indicated that there were two distinct segments among nursing students: traditionals and instrumentals. Traditionals were attracted to nursing as a helping profession while instrumentals were interested in career-related rewards such as variety, mobility, and compensation. These findings were discussed in terms of building awareness and marketing programs for nursing students that are integrated across schools of nursing, private foundations and public agencies.

Water shortages as a result of extreme weather events, such as flooding and severe cold, have the potential to affect significant numbers of people. Therefore, the need to build robust, coordinated plans based on scientific evidence is crucial. The literature review outlined in this short communication was conducted as part of a joint Drinking Water Inspectorate and Health Protection Agency (now Public Health England) report which aimed to review the scientific evidence base on extreme events, water shortages and the resulting health impacts. A systematic literature review was undertaken to identify published literature from both peer-reviewed and grey literature sources. The retrieved literature was then assessed using the Scottish Intercollegiate Guidelines Network quality assessment. The authors found very few scientific studies. However, a great deal of valuable grey literature was retrieved and used by the research team. In total, six main themes of importance that were identified by the review and discussed included health impacts, water quantity and quality, alternative supplies, vulnerable groups, communication with those affected and the emergency response. The authors conclude that more research needs to be conducted on health impacts and extreme events water shortages in order to build the future knowledge base and development of resilience.

Is physical water scarcity a new phenomenon? Global assessment of water shortage over the last two millennia

Kummu, Matti; Varis, Olli; Ward, Philip J; De Moel, Hans

2010-01-01

In this letter we analyse the temporal development of physical population-driven water scarcity, i.e. water shortage, over the period 0 AD to 2005 AD. This was done using population data derived from the HYDE dataset, and water resource availability based on the WaterGAP model results for the period 1961-90. Changes in historical water resources availability were simulated with the STREAM model, forced by climate output data of the ECBilt-CLIO-VECODE climate model. The water crowding index, i.e. Falkenmark water stress indicator, was used to identify water shortage in 284 sub-basins. Although our results show a few areas with moderate water shortage (1000-1700 m 3 /capita/yr) around the year 1800, water shortage began in earnest at around 1900, when 2% of the world population was under chronic water shortage ( 3 /capita/yr). By 1960, this percentage had risen to 9%. From then on, the number of people under water shortage increased rapidly to the year 2005, by which time 35% of the world population lived in areas with chronic water shortage. In this study, the effects of changes in population on water shortage are roughly four times more important than changes in water availability as a result of long-term climatic change. Global trends in adaptation measures to cope with reduced water resources per capita, such as irrigated area, reservoir storage, groundwater abstraction, and global trade of agricultural products, closely follow the recent increase in global water shortage.

The meal is important in life in the space. The importance of space foods is not only health maintenance. The space foods are one of the Life-support system for a space trip. Time for meal is time of the relaxation of home life of the astronaut. However, the breeding of the large animal is still impossible in the spaceship now narrowly. If it is fish and an insect, the breeding in the spaceship is possible. We recognize an insect as ingredients on the earth. As for the insect, possibility to save a food shortage of the earth is expected in future. We suggested the space foods using the insect for 12 years. The cultivation of the insect is pushed forward now in Europe. We suggest a menu to have you know the space foods which took in an insect more. The insect which we used for this menu is silkworm-pupa, a grasshopper, a larva of a wasp and apple snail. The Japanese foods were registered with world's cultural heritage. Therefore we used an insect to make our Japanese foods. Space foods must be universal food. This is because the astronauts are recruited from the whole world. Space foods that a world astronaut eats and thinks to be delicious are necessary. We want to take in an insect in world cooking in future. The insect food includes essential amino acids and essential fatty acid. The insect is superior nutritionally. We will think that insect food is necessary more and more on both the space and the earth in future. The insect is precious ingredients relieving a food shortage for the human.

To describe the perception of the evolution of nursing shortage from 2000 to 2009 according to Nursing Coordinators and the strategies to face it. Nursing coordinators of 11 hospitals or districts of Friuli Venezia Giulia, Trentino Alto Adige and Veneto regions were interviewed in 2000, 2004 and 2009 to collect data and assess their perception on nurses' shortage. In the first interview the medium gap between staff planned and in service was -5.4%; in 2004 -9.4% and in 2009 -3.3%. The shortage, once with a seasonal trend is now constant and appreciated in all the wards. In years 2000 and 2004 on average 5 strategies to face the shortage were implemented, in 2009 7. No systematic strategies have been used with the exception of the unification of wards, mainly during summer for letting people go on holydays. According to Nursing Coordinators the effects of the shortage are already observable (although not quantified) on patients and nurses. The nurses' shortage has been one of the challenges of the last 10 years. Its causes have changed but not the strategies implemented.

Physician shortages in the US are expected to intensify with the implementation of the Patient Protection and Affordable Care Act. These shortages may negatively impact access to care, quality of care, and confidence in the system's ability to adequately provide for health needs in the US. Concerns regarding physician demand underscore how critical Graduate Medical Education funding is to preparing the physician workforce. In 2014 5.6 % of US medical school seniors did not match into residency. Psychology has faced longstanding training imbalance issues with a misalignment between the number of internship positions and the number of applicants. The authors summon attention to the damaging effects a training imbalance poses to a health care profession, its trainees, and ultimately the public it serves.
Unpredictable drug shortages: an ethical framework for short-term rationing in hospitals.

Science.gov (United States)

Rosoff, Philip M

2012-01-01

Periodic and unexpected shortages of drugs, biologics, and even medical devices have become commonplace in the United States. When shortages occur, hospitals and clinics need to decide how to ration their available stock. When such situations arise, institutions can choose from several different allocation schemes, such as first-come, first-served, a lottery, or a more rational and calculated approach. While the first two approaches sound reasonable at first glance, there are a number of problems associated with them, including the inability to make fine, individual patient-centered decisions. They also do not discriminate between what kinds of patients and what types of uses may be more deserving or reasonable than others. In this article I outline an ethically acceptable procedure for rationing drugs during a shortage in which demand outstrips supply.

Shortage and delay in materials supply is argued to be one of the most important factors that lead to delay in construction project delivery globally. However, the relevant underlying reasons vary from country to country. As such, this paper summarises the outcomes of a study that targeted identifying causes of shortage and delay in materials supply in Brunei Darussalam. The study was conducted through fifteen semi-structured interviews of contractors and materials suppliers in Brunei. The study identified six causes of shortageof materials and nine causes of delay in materials supply in Brunei. The most importantcausefor shortage of materials relates to the origin or availability of construction materials. On the other hand, the most influential cause of delay in material supply was found to be poor materials procurement and inventory management system, which has other underlying reasons such as late identification of the type of materials needed. The observations are expected to help in formulating or reviewing relevant policies, in order to ensure on-time project delivery.

Since the electricity market reforms of 2002, two large-scale power shortages, one occurring in 2004 and one in 2011, exerted a tremendous impact on the economic development of China and also gave rise to a fierce discussion regarding electricity system reforms. In this paper, the background and the influence scale of the two power shortages are described. Second, reasons for these two large-scale power shortages are analyzed from the perspectives of power generation, power consumption and coordination of power sources and grid network construction investments. Characteristics of these two large-scale power shortages are then summarized by comparatively analyzing the performance and the formation of the reasons behind these two large-scale power shortages. Finally, some effective measures that take into account the current status of electricity market reforms in China are suggested. This paper concludes that to eliminate power shortages in China, both the supply and the demand should be considered, and these considerations should be accompanied by supervisory policies and incentive mechanisms. - Highlights: • Reasons of these two large-scale power shortages are analyzed. • Characteristics of these two large-scale power shortages are summarized. • Some effective measures to eliminate power shortage are suggested

Full Text Available Croatia is a country of diverse plant use traditions, which are still insufficiently documented. The aim of this study was to document local traditions of using wild food plants around Lake Vrana (northern Dalmatia, Zadar region. We interviewed 43 inhabitants of six traditional villages north of Lake Vrana. On average 12 species were listed, which in total produced an inventory of 55 food plants and 3 fungi taxa. Wild vegetables were most widely collected, particularly by older women who gathered the plants mainly when herding their flocks of sheep. Wild fruits and mushrooms were rarely collected. The former used to be an important supplementary food for children, or for everyone during times of food shortage, and the latter were relatively rare due to the dry climate and shortage of woods. The most commonly collected plants are wild vegetables: Cichorium intybus, Foeniculum vulgare, Sonchus oleraceus, Asparagus acutifolius, Papaver rhoeas, Rumex pulcher, Daucus carota, Allium ampeloprasum and Silene latifolia.
Competence building capacity shortage

Doorman, Gerard; Wangensteen, Ivar; Bakken, Bjoern

2005-02-01

The objective of the project 'Competence Building Capacity Shortage' has been 'to increase knowledge about central approaches aimed at solving the peaking capacity problem in restructured power systems'. With respect to reserve markets, a model was developed in the project to analyze the relations between reserve requirements and prices in the spot and reserve markets respectively. A mathematical model was also developed and implemented, which also includes the balance market, and has a good ability to predict the relations between these markets under various assumptions. With some further development, this model can be used fore realistic analyses of these markets in a Nordic context. It was also concluded that certain system requirements with respect to frequency and time deviation can be relaxed without adverse effects. However, the requirements to system bias, Frequency Activated Operating Reserves and Frequency Activated Contingency Reserves cannot be relaxed, the latter because they must cover the dimensioning fault in the system. On the other hand, Fast Contingency Reserves can be reduced by removing requirements to national balances. Costs can furthermore be reduced by increasingly adapting a Nordic as opposed to national approach. A model for stepwise power flow was developed in the project, which is especially useful to analyze slow power system dynamics. This is relevant when analysing the effects of reserve requirements. A model for the analysis of the capacity balance in Norway and Sweden was also developed. This model is useful for looking at the future balance under various assumptions regarding e.g. weather conditions, demand growth and the development of the generation system. With respect to the present situation, if there is some price flexibility on the demand side and system operators are able to use reserves from the demand side, the probability for load shedding during the peak load hour is close to zero under the weather conditions after

The early introduction of complementary foods is common in Middle Eastern countries but little is known about the determinants of this practice in this region. This prospective cohort study conducted from October 2007 to October 2008 investigated the determinants of the very early (before 17 weeks) introduction of complementary foods in Kuwait and compared rates of this practice against rates reported in the mid-1990s. A total of 373 women were recruited from maternity hospitals in Kuwait City and followed to 26 weeks postpartum. Data on complementary feeding practices were available from 303 women. Multivariate logistic regression was used to estimate the association of very early introduction of complementary foods with infant sex and maternal characteristics including age, years of education, employment intentions at 6 months postpartum, parity, prepregnancy body mass index, and prepregnancy smoking status. All infants had received complementary foods by 26 weeks of age, with 30.4% receiving complementary foods before 17 weeks of age. Women born in other Arabic countries were less likely to introduce complementary foods before 17 weeks (adjusted odds ratio [adj OR] = 0.40; 95% confidence interval [CI], 0.22-0.73) than women born in Kuwait. Women who were exclusively formula feeding at 6 weeks postpartum were less likely to introduce complementary foods before 17 weeks (adj OR = 0.40; 95% CI, 0.23-0.71) than women who were still breastfeeding. Compared to the mid-1990s, fewer infants in Kuwait were receiving complementary foods before 17 weeks. Nevertheless, all infants had received complementary foods by 6 months of age. © The Author(s) 2015.

There have been no reports on the use of "foods allergy disease lifestyle guidance and management forms at day care centers" (life management guidance forms) for understanding details of pupils with food allergies. The contents of lifestyle management guidance forms obtained in Sagamihara city from licensed nurseries were investigated prospectively. We compared and analyzed for the use of life management guidance forms initially in 2013 and in the fiscal year of 2014 in Sagamihara city licensed nurseries. In all, in 2013 and 2014, 9,567 and 10,069 pupils were included in licensed nurseries, and 426 (4.5%) and 447 (4.4%) pupils had food allergies, 61 (0.6%) and 61 (0.6%) had anaphylaxis, respectively.The causative foods in 2013 and 2014, respectively, included unheated hen's egg in 71.6% and 69.6%; heated hen's egg in 54.2% and 54.8%; milk in 23.0% and 23.3%; peanuts in 17.8% and 17.0%; buckwheat in 7.3% and 8.5%; and wheat in 6.3% and 8.3%. There are no significant differences in the distribution of causative foods between 2013 and 2014.Immediate-type food allergy was significantly more frequent in 2014 than in 2013 (73.0% and 78.8%, respectively; p=0.040). Using a life management guidance form will make it easier to manage food allergies in children.

Food irradiation is receiving renewed attention by many individuals--scientists, policy makers, agricultural producers, public health officials, and consumers. Interest in food irradiation’s benefits and limitations has been piqued by recent concerns over the safety of chemical fumigants and preservatives and interest in reducing the incidence of food borne diseases. Individuals concerned with food shortage problems in developing countries are anxious to see if irradiation can be used to eliminate high spoilage losses in those countries. Food processors and retailers are always looking for less costly preservation methods and exploring new techniques to achieve desirable qualities in fresh and processed foods.
The NNP/DNP shortage: transforming neonatal nurse practitioners into DNPs.

Science.gov (United States)

Pressler, Jana L; Kenner, Carole A

2009-01-01

Neonatal nurse practitioners (NNPs) represent a high-demand specialty practice that is especially targeted for US secondary and tertiary care neonatal intensive care units (NICUs). NNPs make primary decisions about the caregiving of high-risk newborns at the time of admission, throughout hospitalization, at transfer, and at discharge that require an advanced knowledge base in neonatology as well as NICU clinical experience. NNPs prepared at the master's level are currently in very short supply, with some estimates suggesting that for each NNP who graduates, there are 80 positions open across the country. Even with the present shortage, due to the high cost of NNP education, NNP programs are diminishing and those that are remaining are not graduating a sufficient number of new NNPs each year to keep up with the demand. To add to the basic shortage problem, in 2004 the American Association of Colleges of Nursing decided that by 2015, the terminal degree for all nurse practitioners should move from the master's degree to the doctor of nursing practice (DNP) degree. That decision added a minimum of 12 months of full-time education to the advanced education requirements for nurse practitioners. What impact will the decision to require a DNP degree have on NNP specialty practice? Will even more NNP programs close because of faculty shortages of NNPs prepared at the DNP level? If a worse shortage occurs in the number of NNPs prepared to practice in NICUs, will physician assistants or other nonphysician clinicians who meet the need for advanced neonatal care providers replace NNPs? What steps, if any, can nursing take to ensure that NNP specialty practice is still needed and survives after supplementing the DNP requirement to NNP education?

As an industry focused on the skill of its workforce, there is now concern the Australian standard in quality, workmanship, and productivity will inhibit both at national and international level.This research paper addresses the underlying, influential factors concerning skills shortages in the Australian construction industry. The influential factors addressed include funding, training statistics, employer expectations, financial limitations, Industrial Relations and immigration. Given the reference to skills shortages within the industry, and documented in related literature, if skills shortages are to continue to exist, their effect will impact upon the overall performance of construction companies throughout Australia.
Xenotransplantation: A Potential Solution to the Critical Organ Donor Shortage

Directory of Open Access Journals (Sweden)

K Howe Sim

1999-01-01

Full Text Available The success of allotransplantation as a treatment for end-stage organ failure has resulted in the need for an increasing number of organ donors. Attempts to meet this need include the use of organs from living related and unrelated donors, financial or other incentives for the donor family, and even the reuse of transplanted organs. Despite these initiatives, the supply of organs for transplantation still falls far short of the demand, as evidenced by longer waiting times for transplantation and decreasing transplantation rates. Even if Canada were able to increase its organ donor rate to that of Spain (40 to 50/million, where organ donation is governed by ‘presumed consent’ legislation, this would not alleviate the problem of donor shortage. Interest in xenotransplantation stems from the need to overcome this increasingly severe shortage of human organs. Indeed, some argue that xenotransplantation is the only potential way of addressing this shortage. As immunological barriers to xenotransplantation are better understood, those hurdles are being addressed through genetic engineering of donor animals and the development of new drug therapies. However, before xenotransplantation can be fully implemented, both the scientific/medical communities and the general public must seriously consider and attempt to resolve the many complex ethical, social and economic issues that it presents.

The aim of the study was to identify a dietary pattern predictive of subsequent annual weight change by using dietary composition information. Study subjects were 24,958 middle-aged men and women of the European Prospective Investigation into Cancer and Nutrition-Potsdam cohort. To derive dietary patterns, we used the reduced rank regression method with 3 response variables presumed to affect weight change: fat density, carbohydrate density, and fiber density. Annual weight change was computed by fitting a linear regression line to each person's body weight data (baseline, and 2- and 4-y follow-up) and determining the slope. In linear regression models, the pattern score was related to annual weight change. We identified a food pattern of high consumption of whole-grain bread, fruits, fruit juices, grain flakes/cereals, and raw vegetables, and of low consumption of processed meat, butter, high-fat cheese, margarine, and meat to be predictive of subsequent weight change. Mean annual weight gain gradually decreased with increasing pattern score (P for trend food pattern was significant only in nonobese subjects. In this study population, we identified a food pattern characterized by high-fiber and low-fat food choices that can help to maintain body weight or at least prevent excess body weight gain.
Public health aspects of food irradiation

Post-harvest losses due to sprouting, insect infestation and spoilage by microorganisms is a serious problem in many countries and commonly aggravates the problem of food shortages. In addition, many developing countries also depend largely on agricultural produce, such as grain, tuber and tropical fruit, as major export crops to earn foreign exchange. The use of ionizing radiation as an effective means of disinfecting and/or prolonging the self-life of several food products has been well documented in a number of developing countries. The World health organization (WHO) encourages its Member States to consider all measures to eliminate or reduce food borne pathogens in food and improve their supplies of safe and nutritious food. In regard to its contribution to food safety, food irradiation may be one of the most significant contributions to public health to be made by food science and technology since the introduction of pasteurization. Because the promotion of a safe, nutritious and adequate food supply is an essential component of its primary health care strategy, WHO is concerned that the unwarranted rejection or limitation of this process may endanger public health and deprive consumers of the choice of foods processed for safety.

The risk of water shortage caused by uncertainties, such as frequent drought, varied precipitation, multiple water resources, and different water demands, brings new challenges to the water transfer projects. Uncertainties exist for transferring water and local surface water; therefore, the relationship between them should be thoroughly studied to prevent water shortage. For more effective water management, an uncertainty-based water shortage risk assessment model (UWSRAM) is developed to study the combined effect of multiple water resources and analyze the shortage degree under uncertainty. The UWSRAM combines copula-based Monte Carlo stochastic simulation and the chance-constrained programming-stochastic multiobjective optimization model, using the Lunan water-receiving area in China as an example. Statistical copula functions are employed to estimate the joint probability of available transferring water and local surface water and sampling from the multivariate probability distribution, which are used as inputs for the optimization model. The approach reveals the distribution of water shortage and is able to emphasize the importance of improving and updating transferring water and local surface water management, and examine their combined influence on water shortage risk assessment. The possible available water and shortages can be calculated applying the UWSRAM, also with the corresponding allocation measures under different water availability levels and violating probabilities. The UWSRAM is valuable for mastering the overall multi-water resource and water shortage degree, adapting to the uncertainty surrounding water resources, establishing effective water resource planning policies for managers and achieving sustainable development.

Review: Feed demand landscape and implications of food-not feed strategy for food security and climate change.

Science.gov (United States)

Makkar, H P S

2017-12-04

The food-feed competition is one of the complex challenges, and so are the ongoing climate change, land degradation and water shortage for realizing sustainable food production systems. By 2050 the global demand for animal products is projected to increase by 60% to 70%, and developing countries will have a lion's share in this increase. Currently, ~800 million tonnes of cereals (one-third of total cereal production) are used in animal feed and by 2050 it is projected to be over 1.1 billion tonnes. Most of the increase in feed demand will be in developing countries, which already face many food security challenges. Additional feed required for the projected increased demand of animal products, if met through food grains, will further exacerbate the food insecurity in these countries. Furthermore, globally, the production, processing and transport of feed account for 45% of the greenhouse gas emissions from the livestock sector. This paper presents approaches for addressing these challenges in quest for making livestock sector more sustainable. The use of novel human-inedible feed resources such as insect meals, leaf meals, protein isolates, single cell protein produced using waste streams, protein hydrolysates, spineless cactus, algae, co-products of the biofuel industry, food wastes among others, has enormous prospects. Efficient use of grasslands also offers possibilities for increasing carbon sequestration, land reclamation and livestock productivity. Opportunities also exist for decreasing feed wastages by simple and well proven practices such as use of appropriate troughs, increase in efficiency of harvesting crop residues and their conversion to complete feeds especially in the form of densified feed blocks or pellets, feeding as per the nutrient requirements, among others. Available evidence have been presented to substantiate arguments that: (a) for successful and sustained adoption of a feed technology, participation of the private sector and a sound

Official attitude towards irradiated food is determined by factors such as: level of scientific knowledge, consumer habits, food shortages, agricultural production and technological know-how. To date, 39 countries have accepted the process for one or more food items while 27 nations carry out the process on a commercial basis. Regulations and codes of practice is essential for consumer confidence while uniformity of regulations, at the international level, will enhance international trade in irradiated food items. The internationally accepted Codex Standard on irradiated food and Codes of Practice for the operation of irradiation facilities, adopted in 1983, forms the basis for International regulations and a template for nations in the development of regulations. This paper discusses the basic legal requirements for licensing the process, procedures, facility and the operator and suggests a framework for a national regulation based on experiences of Hungary, Brazil and Israel

Role of PPAR-gamma in inflammation. Prospects for therapeutic intervention by food components

International Nuclear Information System (INIS)

Martin, Harry

2009-01-01

Peroxisome proliferator activated receptor gamma (PPARγ) is a ligand-dependent transcription factor and a member of the nuclear receptor superfamily. Acting as sensors of hormones, vitamins, endogenous metabolites and xenobiotic compounds, the nuclear receptors control the expression of a very large number of genes. PPARγ has been known for some time to regulate adipocyte differentiation, fatty acid storage and glucose metabolism, and is a target of anti-diabetic drugs. More recently, PPARγ has been recognized as playing a fundamentally important role in the immune response through its ability to inhibit the expression of inflammatory cytokines and to direct the differentiation of immune cells towards anti-inflammatory phenotypes. A feature of PPARγ is the structural diversity of its ligands, which encompass endogenous metabolites, dietary compounds and synthetic drugs. The high and increasing incidence of inflammatory and allergic disease, coupled with encouraging results from recent clinical trials, suggest that natural PPARγ agonists found in foods may be beneficial to human health by acting as anti-inflammatory molecules. PPARγ is therefore not only a target of the pharmaceutical industry, but also of great potential interest to the food industry, since it is activated by several natural dietary constituents. The prospects for dietary intervention in inflammatory disease have improved somewhat over the last few years, and are reviewed here.

Wolfe, William A

2014-01-01

Nephrology nurse shortages have historically been viewed as a subset of the overall nursing supply in the United States. Not-here-to-fore considered as a contributing factor are the effects of word-of-mouth and Internet-based word-of-mouth communications from nurses who have had disappointing work experiences in hemodialysis clinics. This article discusses the potential effects of word-of-mouse communications and posits that negative word-of-mouse communications may discourage new and experienced nurses from considering the specialty of nephrology nursing, thus contributing to a nephrology nursing shortage.

Massey, Anna; Hill, Andrew J

2012-06-01

Evidence linking food restriction and food craving is equivocal. This study investigated whether dieting was associated with a greater frequency of food craving. Dieting to lose weight was distinguished from watching so as not to gain weight. Participants were 129 women (mean age=41 yrs): 52 were currently dieting to lose weight, 40 were watching their weight, and 37 were non-dieters. They completed a food craving record after every food craving, a food diary, and a daily mood assessment over 7-days. Of the 393 craving incidents recorded, dieters experienced significantly more food cravings than non-dieters, with watchers intermediate. Chocolate was the most craved food (37% of cravings) but neither the types of food, the proportion of cravings leading to eating (∼70%), the situations in which cravings occurred, nor the time since the last eating episode differed between groups. Compared with non-dieters, dieters experienced stronger cravings that were more difficult to resist, and for foods they were restricting eating. Watchers showed similarities in experience both to dieters (low hunger) and non-dieters (lower craving intensity). These results support an association between dieting and food craving, the usefulness of distinguishing dieting to lose weight and watching, and suggest a need for further experimental investigation of actual food restriction on food craving experiences.

Potential food shortages, human health challenges and environmental concerns, all thematically linked to growing and aging global populations, drive the search for alternative and sustainable food sources. Insects, which have been part of the human diet since antiquity though not currently widely consumed in Western societies, are rich in high quality proteins and nutrients and bioactives. Accordingly, insects could make a significant contribution to the global food supply chain in the future. This review explores the potential of entomophagy in an integrated global food network and focuses on practical approaches for transforming insect biomass into consumer food products. Carefully regulated breeding, rearing, harvesting and processing of insect bioresources are critical for realising the concept of "edible insects for human well-being". Copyright © 2016 Elsevier Ltd.

Mandasari, P.

2018-03-01

Despite the fact that environmental consequences derived from food waste have been widely known, studies on the amount of food waste and its influencing factors have relatively been paid little attention. Addressing this shortage, this paper aimed to quantify monthly avoidable food waste generated by Indonesian undergraduate students and analyse factors influencing the occurrence of avoidable food waste. Based on data from 106 undergraduate students, descriptive statistics and logistic regression were applied in this study. The results indicated that 4,987.5 g of food waste was generated in a month (equal to 59,850 g yearly); or 47.05 g per person monthly (equal to 564.62 g per person per a year). Meanwhile, eating out frequency and gender were found to be significant predictors of food waste occurrence.

In the paper, a grey forecasting model and a population growth model are established for forecasting water resources supply and demand situation in the region, and evaluating the scarcity of water resources thereof in order to solve the problem of water shortage in North China. A concrete plan for alleviating water resources pressure is proposed with AHP as basis, thereby discussing the feasibility of the plan. Firstly, water resources supply and demand in the future 15 years are predicted. There are four sources for the demand of water resources mainly: industry, agriculture, ecology and resident living. Main supply sources include surface water and underground water resources. A grey forecasting method is adopted for predicting in the paper aiming at water resources demands since industrial, agricultural and ecological water consumption data have excessive decision factors and the correlation is relatively fuzzy. Since residents' water consumption is determined by per capita water consumption and local population, a logistic growth model is adopted to forecast the population. The grey forecasting method is used for predicting per capita water consumption, and total water demand can be obtained finally. International calculation standards are adopted as reference aiming at water supply. The grey forecasting method is adopted for forecasting surface water quantity and underground water quantity, and water resources supply is obtained finally. Per capita water availability in the region is calculated by comparing the water resources supply and demand. Results show that per capita water availability in the region is only 283 cubic meters this year, people live in serious water shortage region, who will suffer from water shortage state for long time. Then, sensitivity analysis is applied for model test. The test result is excellent, and the prediction results are more accurate. In the paper, the following measures are proposed for improving water resources condition

To document food acquisition experiences during Iraqi military occupation in Kuwait. Retrospective cross-sectional study. Urban areas in Kuwait during occupation. Those living in Kuwait during the period of occupation, and aged between 15 to 50 years at the time of occupation, recruited by snowball sampling. A total of 390 completed questionnaires (response rate 78%, 202 female and 188 male) were returned. During the occupation, food became increasingly difficult to acquire. Two food systems emerged: (i) an underground Kuwaiti network linked to foods recovered from local food cooperatives and (ii) a black market supplied by food imported through Iraq or stolen locally. Food shortages led to reductions in meal size and frequency. Some respondents (47·7%) reported not having sufficient income to purchase food and 22·1% had to sell capital items to purchase food. There was a significant increase (Pbehaviour change. Respondents reported deterioration in the quality and availability of fish, milk, and fruit in particular. Despite a decrease in opportunities for physical activity, most respondents reported that they lost weight during the occupation. Although the Kuwaiti population fell by about 90 % and domestic food production increased during the 7-month occupation, the local population continued to rely heavily on imported food to meet population needs. The high prevalence of self-reported weight loss indicates the inadequacies of this food supply. High apparent food security in systems which significantly exceed the ecological carrying capacity of the local environment and rely on mass food importation remains vulnerable.

Mycotoxins, which are toxic, carcinogenic, and/or teratogenic, have posed a threat to food safety and public health. Sensitive and effective determination technologies for mycotoxin surveillance are required. Immunoassays have been regarded as useful supplements to chromatographic techniques. However, conventional antibodies involved in immunoassays are difficult to be expressed recombinantly and are susceptible to harsh environments. Nanobodies (or VHH antibodies) are antigen-binding sites of the heavy-chain antibodies produced from Camelidae. They are found to be expressed easily in prokaryotic or eukaryotic expression systems, more robust in extreme conditions, and facile to be used as surrogates for artificial antigens. These properties make them the promising and environmentally friendly immunoreagents in the next generation of immunoassays. This review briefly describes the latest developments in the area of nanobodies used in mycotoxin detection. Moreover, by integrating the introduction of the principle of nanobodies production and the critical assessment of their performance, this paper also proposes the prospect of nanobodies in the field of food safety in the foreseeable future.

2015-12-01

Global climate change, unprecedented population growth, and rapid urbanization have elevated the possibility of food and water shortages in many regions across the world. The likelihood of such shortages in the future is further exacerbated by the fact that increased greenhouse forcing and rapid growth in human population will continue for at least the next several decades. These socio-environmental changes will likely put some regions under enormous economic and environmental stress by forcing them to adapt to new conditions. India with its rapidly growing population and high rates of urbanization and industrialization is one such region whose agricultural resources will be particularly vulnerable to the impact of these changes. This study collectively reviews and analyses the possible impacts of climate change, population growth and resulting land use change on the availability of food and water in the coming decades for India. By analyzing and fusing a wide variety of existing data and research on the impact of land use change, population, and climate change, on water and food resources this study develops an understanding of the broader implications of each of the changes on food security in the region. In addition, the study focuses on the need to assess and quantify the combination of such impacts at a regional level and identify food security hotspots spatially across India that will help to narrow down regions in the country which will be severely affected and need priority adaptation and mitigation measures.

Full Text Available The nursing shortage is a common problem throughout the world. Nurses form the largest proportion of the healthcare system and play a significant role in providing direct patient care. Considering the importance of the role of nurses in the healthcare system, it is important to investigate how nursing shortage effects the quality of patient care, nurses’ job satisfaction and their work stress. A study was conducted to investigate the correlation between these at the Polonnaruwa District General Hospital in Sri Lanka with a random sample of nurses working in the hospital and using a self-administered questionnaire. This study uses an explanatory research design. The statistical analysis confirmed a positive relationship between nurse shortage and workload. It also shows a significant positive relationship between workload and the quality of patient care. Furthermore, a negative relationship was observed between workload and the quality of patient care. In addition, this study calculates the mean effect of emotional intelligence of these factors, and a significant correlation is found between emotional intelligence and workload as well as work stress. There is a firm evidence that in Sri Lanka, nursing shortage influences the workload of the employee, finally affecting the quality of patient care. In addition, the study recognized the capability of nurses to manage their emotions as well as emotions of others, which has increased their tolerance to control psychological stress in performing their duty. This study confirms that nurse’s emotional intelligence act as a partial oderating variable for job outcomes of nurses.
Prospects of using natural antioxidants in radiation processed food

Full text: Microbial contamination of food is a serious concern both for food producer and consumer. Radiation processing of food is one of the most effective technologies that can extend the shelf-life and eliminate pathogenic bacteria in food. However, wide acceptability of radiation processed food products will depend upon quality parameters such as oxidative changes, color stability and organoleptic attributes. Any food processing technique is known to accelerate lipid peroxidation and radiation processing is no exception. Irradiation does not adversely affect the overall nutritive value of food and the oxidative changes induced by irradiation are similar to those observed using conventional food processing methods. Combination of various processing conditions such as storage and cooking, results in accelerated oxidative deterioration. The growing demand for convenience foods and the evolving markets for pre cooked food, call for techniques to prevent lipid oxidation in prepared stored food. Products of lipid peroxidation adversely affect the color, flavor and texture of the food. It is therefore necessary to control these changes for better product development. Methods commonly employed by the food industry include the use of antioxidants. Presently, most of the antioxidants used are synthetic but consumer concern has become a driving force for exploring the use of natural antioxidants. The increase interest in substitution of synthetic antioxidants with natural antioxidants has fostered research on screening of plant materials in order to identify new compounds. We have investigated the antioxidant potential of several plant extracts, herbs and waste generated by the food industry, such as potato peel, banana peel, mango peel, mint, cinnamon extracts and chitosan. Mint extract was found to have the maximum antioxidant activity as tested by several in vitro antioxidant assays. The antioxidant activity of mint extract was comparable to that of BHT the commonly
A New Way for Incorporating GCM Information into Water Shortage Projections

Full Text Available Climate change information is essential for water resources management planning, and the majority of research available uses the global circulation model (GCM data to project future water balance. Despite the fact that the results of various GCMs are still heterogeneous, it is common to utilize GCM values directly in climate change impact assessment models. To mitigate these limitations, this study provides an alternative methodology, which uses GCM-based data to assign weights on historical scenarios rather than to directly input their values into the assessment models, thereby reducing the uncertainty involved in the direct use of GCMs. Therefore, the real innovation of this study is placed on the use of a new probability weighting scheme with multiple GCMs rather than on the direct input of GCM-driven data. Applied to make future projections of the water shortage in the Han River basin of Korea, the proposed methodology produced conservative but realistic projection results (15% increase compared to the existing methodologies, which projected a dramatic increase (144% in water shortage over 10 years. As a result, it was anticipated that the amount of water shortages in the Han River basin would gradually increase in the next 90 years, including a 57% increase in the 2080s.

The use of allergy tests to guide dietary treatment for eosinophilic oesophagitis (EoE) is controversial and data are limited. Aeroallergen sensitisation patterns and food triggers have been defined in Northern Hemisphere cohorts only. To determine if allergy tests that are routinely available can predict food triggers in adult patients with EoE. To define the food triggers and aeroallergen sensitisation patterns in a novel Southern Hemisphere (Australian) cohort of patients. Consecutive patients with EoE who elected to undergo dietary therapy were prospectively assessed, demographic details and atopic characteristics recorded, and allergy tests, comprising skin-prick and skin-patch tests, serum allergen-specific IgE, basophil activation test and serum food-specific IgG, were performed. Patients underwent a six-food elimination diet with a structured algorithm that included endoscopic and histological examination of the oesophagus a minimum of 2 weeks after each challenge. Response was defined as Foods defined as triggers were considered as gold standard and were compared with those identified by allergy testing. No allergy test could accurately predict actual food triggers. Concordance among skin-prick and serum allergen-specific IgE was high for aeroallergens only. Among seasonal aeroallergens, rye-grass sensitisation was predominant. Food triggers were commonly wheat, milk and egg, alone or in combination. None of the currently-available allergy tests predicts food triggers for EoE. Exclusion-rechallenge methodology with oesophageal histological assessment remains the only effective investigation. The same food triggers were identified in this southern hemisphere cohort as previously described. © 2016 John Wiley & Sons Ltd.

Greece has been seriously affected by the economic crisis. In 2011 there were reports of 40% reduction to public hospital budgets. Occasional shortages of medical supplies have been reported in mass media. We attempted to pivotally investigate the frequency of medical supplies shortages in two Greek hospital units of the National Health System and to also assess their possible impact on burnout risk of health care workers. We conducted a cross-sectional study (n=303) of health care workers in two Greek hospitals who were present at the workplace during a casually selected working day (morning shift work). The Maslach Burnout Inventory (MBI) was used as the measure of burnout. An additional questionnaire was used about demographics, and working conditions (duration of employment, cumulative night shifts, type of hospital including medical supplies shortages and their impact on quality of healthcare. The prevalence of emotional exhaustion, depersonalization and low personal accomplishment was 44.5%, 43.2% and 51.5%, respectively. Medical supply shortages were significantly associated with emotional exhaustion and depersonalization. This finding provides preliminary evidence that austerity has affected health care in Greece. Moreover, the medical supply shortages in Greek hospitals may reflect the unfolding humanitarian crisis of the country. PMID:24688306
Minding the gap: World Bank's assistance to power shortage mitigation in the developing world

Heffner, G.; Maurer, L.; Sarkar, A.; Wang, X. [The World Bank, 1818 H Street, NW, Washington DC 20433 (United States)

2010-04-15

This paper describes the World Bank's technical assistance and lending efforts in support of developing countries facing power shortages. The paper reviews the World Bank's experience in helping governments to mitigate power shortages in Africa, South Asia, East Asia, and Latin America regions. The paper stresses the need to consider each power ''crunch'' on an individual basis, and describes the process used in diagnosing a shortage situation and prescribing mitigation strategies. Several brief case studies are presented, including Botswana, Brazil, Uganda, and South Africa. The political and customer-centric dimensions of power shortage mitigation are briefly described, with suggestions for minimizing the socio-economic impacts of power shortages on the urban and rural poors. The paper concludes that an integrated supply-demand portfolio approach works best, and within the portfolio a mix of market-based rationing, emergency mobilization of customer-owned generation, interruptible rates, load control, and energy efficient lighting should be sought. Although the best formulation will vary according to market structure, demand composition, and nature of the crisis, World Bank practitioners have found one program that works almost everywhere to produce fast and effective results - mass market Compact Fluorescent Lamp (CFL) replacement programs.

Satisfaction in nursing in the context of shortage.

Science.gov (United States)

Morgan, Jennifer Craft; Lynn, Mary R

2009-04-01

This paper describes the central themes nurses identify as important to their overall evaluation of their work. In particular, this paper highlights how the context of the nursing shortage interacts with what nurses understand to be satisfying about their work. On the brink of a current and enduring nursing shortage in the US, this study provides Nurse Managers with an understanding of the dimensions of work satisfaction which they can then utilize to improve retention of incumbent nurses. Semi-structured interviews were conducted with 20 currently employed nurses to explore the concepts that shape their work satisfaction. The nurses, 25 to 55 years old, were predominantly female and Associate Degree or Baccalaureate prepared. Nurses have both intrinsic and extrinsic satisfiers in their work. The traditional satisfiers (pay and benefits) are not the principle satisfiers of today's nurses. In the context of shortage, the aspects of nursing that are the most rewarding are the aspects that are most often sacrificed in the interest of 'getting the job done'. Nurses are finding it difficult to continue to do 'more with less' and are frustrated they are not able to provide the care they were educated to be able to deliver. The description of the dimensions of work satisfaction can provide insight for Nurse Managers and administrators who are interested in improving both recruitment and retention of nurses. Areas identified worthy of focus in retention efforts include: increasing autonomy; reallocating work in a more patient-centred way; creating systems to recognize achievement in the areas of mentoring nurses, educating patients and personal growth in practice; creating meaningful internal labour markets; and enhancing supervisor and administrative support. Managers and administrators should focus on the satisfiers nurses identify if they wish to retain nurses. The traditional focus on extrinsic rewards will not likely be sufficient to retain today's nurses. Retention

Lipo-Dox utilizes a different liposomal particle than Doxil and demonstrates different pharmacokinetic properties. Its use has never been evaluated in a North American population. The objective of this study was to evaluate the efficacy and tolerability of Lipo-Dox at Magee-Womens Hospital, University of Pittsburgh Medical Center, for patients with recurrent epithelial ovarian cancer who were treated during the Doxil shortage. Methods: Patients treated with Lipo-Dox from January 2012 to December 2012 were identified retrospectively. Disease response was defined radiographically by RECIST (Response Evaluation Criteria in Solid Tumors or biochemically by CA-125 level if measurable disease was not present. Survival was defined from the start date of Lipo-Dox until the date of progression or death. Toxicity was assessed by the Gynecologic Oncology Group common toxicity criteria. Results: Eighteen patients with recurrent epithelial ovarian cancer who received Lipo-Dox were identified. These patients had a median of three prior treatment regimens. The median number of Lipo-Dox cycles given was 3.5 (range 1–8. No patients had a complete or partial response. Two patients had stable disease over a mean follow-up of 144.5 days. Fourteen patients had progressive disease, with a median time to progression of 82 days. Progression was based on CA-125 in four patients and RECIST in the remainder. Nine patients died from the disease. Conclusion: Although this represents a small, pretreated population, there were no clinical

2017-03-01

99m Tc, the most common radioisotope used in nuclear medicine, is produced in a nuclear reactor from the decay of 99 Mo. There are only a few aging nuclear reactors around the world that produce 99 Mo, and one of the major contributors, the National Research Universal (Canada), ceased production on October 31, 2016. The National Research Universal produced approximately 40% of the world's 99 Mo supply, so with its shut down, shortages of 99 Mo/ 99m Tc are expected. Methods: Nuclear pharmacies and nuclear medicine departments throughout the United States were contacted and asked to provide their strategies for coping with a shortage of 99 Mo/ 99m Tc. Each of these strategies was evaluated on the basis of its effectiveness for conserving 99m Tc while still meeting the needs of the patients. Results: From the responses, the following 6 categories of strategies, in order of importance, were compiled: contractual agreements with commercial nuclear pharmacies, alternative imaging protocols, changes in imaging schedules, software use, generator management, and reduction of ordered doses or elimination of backup doses. Conclusion: The supply chain of 99 Mo/ 99m Tc is quite fragile; therefore, being aware of the most appropriate coping strategies is crucial. It is essential to build a strong collaboration between the nuclear pharmacy and nuclear medicine department during a shortage situation. With both nuclear medicine departments and nuclear pharmacies implementing viable strategies, such as the ones proposed, the amount of 99m Tc available during a shortage situation can be maximized. © 2017 by the Society of Nuclear Medicine and Molecular Imaging.

In September 2011, a total of 511 human cases of anthrax (Bacillus anthracis) infection and 5 deaths were reported in a game management area in the district of Chama, Zambia, near where 85 hippopotamuses (Hippopotamus amphibious) had recently died of suspected anthrax. The human infections generally responded to antibiotics. To clarify transmission, we conducted a cross-sectional, interviewer-administered household survey in villages where human anthrax cases and hippopotamuses deaths were reported. Among 284 respondents, 84% ate hippopotamus meat before the outbreak. Eating, carrying, and preparing meat were associated with anthrax infection. Despite the risk, 23% of respondents reported they would eat meat from hippopotamuses found dead again because of food shortage (73%), lack of meat (12%), hunger (7%), and protein shortage (5%). Chronic food insecurity can lead to consumption of unsafe foods, leaving communities susceptible to zoonotic infection. Interagency cooperation is necessary to prevent outbreaks by addressing the root cause of exposure, such as food insecurity.

Alghoul, M. A.; Ali, Amer; Kannanaikal, F. V.; Amin, N.; Sopian, K.

2017-11-01

PV power systems have been commercially available and widely used for decades. The performance of a reliable PV system that fulfils the expectations requires correct input data and careful design. Inaccurate input data of the techno-economic feasibility would affect the size, cost aspects, stability and performance of PV power system on the long run. The annual capacity shortage is one of the main input data that should be selected with careful attention. The aim of this study is to reveal the effect of different annual capacity shortages on the techno-economic feasibility parameters and determining the optimal value for Baghdad city location using HOMER simulation tool. Six values of annual capacity shortage percentages (0%, 1%, 2%, 3%, 4%, and 5%), and wide daily load profile range (10 kWh - 100 kWh) are implemented. The optimal annual capacity shortage is the value that always "wins" when each techno-economic feasibility parameter is at its optimal/ reasonable criteria. The results showed that the optimal annual capacity shortage that reduces significantly the cost of PV power system while keeping the PV system with reasonable technical feasibility is 3%. This capacity shortage value can be carried as a reference value in future works for Baghdad city location. Using this approach of analysis at other locations, annual capacity shortage can be always offered as a reference value for those locations.

The rapidly growing world population and rising consumption of biofuels are increasing demand for both food and biofuels. This exaggerates both food and fuel shortages. Using food crops such as corn grain to produce ethanol raises major nutritional and ethical concerns. Nearly 60% of humans in the world are currently malnourished, so the need for grains and other basic foods is critical. Growing crops for fuel squanders land, water and energy resources vital for the production of food for human consumption. Using corn for ethanol increases the price of U.S. beef, chicken, pork, eggs, breads, cereals, and milk more than 10% to 30%. (author)

To examine whether baseline chronic stress, morning cortisol, and other appetite-related hormones (leptin, ghrelin, and insulin) predict future weight gain and food cravings in a naturalistic, longitudinal, 6-month follow-up study. A prospective community cohort of 339 adults (age 29.1 ± 9.0 years; BMI = 26.7 ± 5.4 kg/m 2 ; 56.9% female; 70.2% white) completed assessments at baseline and 6-month follow-up. Fasting blood draws were used to assess cortisol and other appetite-related hormone levels at baseline. At baseline and follow-up, body weight was measured, and the Cumulative Adversity Interview and Food Craving Inventory were administered. Data were analyzed using linear mixed models adjusting for demographic and clinical covariates. Over the 6-month period, 49.9% of the sample gained weight. Food cravings and chronic stress decreased over 6 months (Ps < 0.05). However, after adjusting for covariates, individuals with higher baseline total ghrelin had significantly higher food cravings at 6 months (P = 0.04). Furthermore, higher cortisol, insulin, and chronic stress were each predictive of greater future weight gain (Ps < 0.05). These results suggest that ghrelin plays a role in increased food cravings and reward-driven eating behaviors. Studies are needed that examine the utility of stress reduction methods for normalizing disrupted cortisol responses and preventing future weight gain. © 2017 The Obesity Society.

To date, it is unclear whether individuals with celiac disease following a gluten-free (GF) diet for several years have adequate intake of all recommended nutrients. Lack of a food frequency questionnaire (FFQ) for individuals with celiac disease could be partly responsible for this still-debated issue. The aim of the study is to evaluate the performance of a modified European Prospective Investigation into Cancer and Nutrition (EPIC) FFQ in estimating nutrient and food intake in a celiac population. In a cross-sectional study, the dietary habits of individuals with celiac disease were reported using a modified Italian EPIC FFQ and were compared to a 7-day weighed food record as a reference method. A total of 200 individuals with histologically confirmed celiac disease were enrolled in the study between October 2012 and August 2014 at the Center for Prevention and Diagnosis of Celiac Disease (Milan, Italy). Nutrient and food category intake were calculated by 7-day weighed food record using an Italian food database integrated with the nutrient composition of 60 GF foods and the modified EPIC FFQ, in which 24 foods were substituted with GF foods comparable for energy and carbohydrate content. An evaluation of the modified FFQ compared to 7-day weighed food record in assessing the reported intake of nutrient and food groups was conducted using Spearman's correlation coefficients and weighted κ. One hundred individuals completed the study. The Spearman's correlation coefficients of FFQ and 7-day weighed food record ranged from .13 to .73 for nutrients and from .23 to .75 for food groups. A moderate agreement, which was defined as a weighted κ value of .40 to .60, was obtained for 30% of the analyzed nutrients, and 40% of the nutrients showed values between .30 and .40. The weighted κ exceeded .40 for 60% of the 15 analyzed food groups. The modified EPIC FFQ demonstrated moderate congruence with a weighed food record in ranking individuals by dietary intakes

Is The Water Shortage Crisis Really One of the Most Dangerous?

Author of the 1998 book, Last Oasis: Facing Water Scarcity, Dr. Sandra Postel predicts big water availability problems as populations of so-called “water-stressed” countries jump perhaps six fold over the next 30 years. The author has reported on this in his previous AGU presentations. In the next four decades, more than half of the world’s population will have to deal with sever water shortages. The United States has been blessed with several large fresh water lakes. In spite of having this fresh water supply, some states like Arizona could be facing sever fresh water shortages in the next couple of decades. Sid Wilson, general manager of the Central Arizona Project has indicated "It's not a question of if there is a water shortage anymore. It is in reality, when there will be a water shortage. " Several states share water from the Colorado river. The river has limited water supply to cater to the needs of Arizona, Nevada, California, Colorado, New Mexico, Utah and Wyoming. World Health Organization, NASA, Department of the Interior, NOAA and several organizations have observed that there is a real water shortage crisis. This is because the world’s population has tripled in the twentieth century. This has resulted in a six-fold increase of water usage. Fresh water supply is limited. This is because water cannot be replaced with an alternative. It is important to observe that petroleum can be replaced with alternative fuel resources. It is necessary to recognize that fact that irrigation necessitates almost 65% to 70% of water withdrawal. Industry may utilize about 20% and domestic consumption is about 10% Evaporation from reservoirs is also a major factor, depending upon the climate and environment. Therefore there is an urgent need for all the countries to establish a strong, sound, sensible and sustainable management program for utilizing the available water supplies efficiently (Narayanan, 2008).

Dang, V.D.; Steinberg, M.

1975-06-01

Food and energy shortages in many parts of the world in the past two years raise an immediate need for the evaluation of energy input in food production. The present paper investigates systematically (1) the energy requirement for food production, and (2) the provision of controlled thermonuclear fusion energy for major energy intensive sectors of food manufacturing. Among all the items of energy input to the ''food industry,'' fertilizers, water for irrigation, food processing industries, such as beet sugar refinery and dough making and single cell protein manufacturing, have been chosen for study in detail. A controlled thermonuclear power reactor was used to provide electrical and thermal energy for all these processes. Conceptual design of the application of controlled thermonuclear power, water and air for methanol and ammonia synthesis and single cell protein production is presented. Economic analysis shows that these processes can be competitive. (auth)
Prospects of eliminating pathogens by the process of food irradiation

International Nuclear Information System (INIS)

Kampelmacher, E.H.

1981-01-01

Food-borne diseases are an increasing health hazard throughout the world. Some of these diseases, such as salmonellosis, staphylo-entero-toxicosis, botulism, vibriosis and parasitic infections have always played an important role, whereas some other food-borne pathogens, such as Campylobacter, Vibrio parahaemolyticus and toxin-producing fungi have only been recognised in recent decades. Changing food-production methods, food processing and especially food habits, together with the enormous trade in foods and feeds from one part of the world to the other, are responsible for the increase of these diseases. To meet this situation, prevention and control of food-borne diseases, which involve large groups of persons and play a major socio-economic role in many parts of the world, are of utmost importance. In prevention and control programmes food irradiation can be applied successfully and may solve some of the food and feed contamination problems. The author summarizes to-day's most important food-borne diseases, the type of foods which are responsible for infections in man and animals, and the commodities in which low-dose food irradiation may be of great value in preventing these diseases. The advantages of irradiation versus the use of chemical additives and pesticides and with respect to the prevention of cross-contamination (which plays a very important role in initiating food-borne diseases) by pre-packaging, are emphasized. The required irradiaton doses to eliminate or reduce the number of pathogenic organisms which may be present in foods, the problem of radioresistance and the acceptability of irradiated food are discussed. Finally to-day's situation of irradiated foods with regard to legislation, consumers' information and economic feasibility is summarized. (author)
Inventory Model for Deteriorating Items Involving Fuzzy with Shortages and Exponential Demand

2015-11-01

Full Text Available This paper considers the fuzzy inventory model for deteriorating items for power demand under fully backlogged conditions. We define various factors which are affecting the inventory cost by using the shortage costs. An intention of this paper is to study the inventory modelling through fuzzy environment. Inventory parameters, such as holding cost, shortage cost, purchasing cost and deterioration cost are assumed to be the trapezoidal fuzzy numbers. In addition, an efficient algorithm is developed to determine the optimal policy, and the computational effort and time are small for the proposed algorithm. It is simple to implement, and our approach is illustrated through some numerical examples to demonstrate the application and the performance of the proposed methodology.

Establishment of a world food preservation center

Wilson Charles L

2013-01-01

Full Text Available Abstract A World Food Preservation Center (WFPC is proposed in response to a pending civilization-threatening food shortage and our limited ability to adequately increase food production. Some estimates put losses of food in developing countries after it is produced and before it is consumed at 50%. These losses are particularly threatening to individuals and farmers who are living in the midst of food insecurity. Although numerous organizations have attempted to address this problem worldwide, the magnitude of the effort has not come close to the enormity of the problem. Most of these programs are also short-term and require continuous input by postharvest specialists from developed countries in order to be sustainable. A critical need exists for a substantial and sustainable worldwide program that can significantly reduce losses and waste of food in developing countries. The World Food Preservation Center proposed here meets this need by educating young scientists in developing countries about low-input, appropriate technologies for preserving food postharvest. It also conducts research on postharvest technologies especially suited for application in developing countries such as biological control, solar refrigeration, and coordinated transport and marketing schemes that support and sustain the local production of food commodities.

The aim of this systematic review and meta-analysis was to synthesize the knowledge about the relation between intake of 12 major food groups and risk of type 2 diabetes (T2D). We conducted a systematic search in PubMed, Embase, Medline (Ovid), Cochrane Central, and Google Scholar for prospective studies investigating the association between whole grains, refined grains, vegetables, fruits, nuts, legumes, eggs, dairy, fish, red meat, processed meat, and sugar-sweetened beverages (SSB) on risk of T2D. Summary relative risks were estimated using a random effects model by contrasting categories, and for linear and non-linear dose-response relationships. Six out of the 12 food-groups showed a significant relation with risk of T2D, three of them a decrease of risk with increasing consumption (whole grains, fruits, and dairy), and three an increase of risk with increasing consumption (red meat, processed meat, and SSB) in the linear dose-response meta-analysis. There was evidence of a non-linear relationship between fruits, vegetables, processed meat, whole grains, and SSB and T2D risk. Optimal consumption of risk-decreasing foods resulted in a 42% reduction, and consumption of risk-increasing foods was associated with a threefold T2D risk, compared to non-consumption. The meta-evidence was graded "low" for legumes and nuts; "moderate" for refined grains, vegetables, fruit, eggs, dairy, and fish; and "high" for processed meat, red meat, whole grains, and SSB. Among the investigated food groups, selecting specific optimal intakes can lead to a considerable change in risk of T2D.

Tunisia is a country with a high vocational agricultural orientation. It continues to promote production and gives incentives to construct storage and processing installations in order to meet the food demand of the growing population. This policy is part of a global development program aimed at reaching a food security system. This system is based not only on increasing production but also on the improvement of the storage and processing capacities existing in the country, whether modern or traditional, taking in consideration the food commodities and the region concerned. Food preservation by irradiation is an alternative to improve and reinforce our food security system, since it is considered as a way to protect commodities from spoilages and also to promote shelf life and improve hygienic qualities. The products which are concerned by decreasing losses are mainly potatoes, onions garlic, dates, nuts, etc. Hygiene improvement will concern poultry products for our growing tourist business. And, shelf extension concerns our exports of sea product to the european community. Within this scope the government of tunisia has submitted a proposal to install a pilot unit to carry out preliminary work toward the introduction of an industrial unit. The international atomic energy agency has accepted the proposal and is looking for funds for the implementation. The government has recently pledged 60.000 tunisian dinars to do the required engineering studies of the unit. 4 tabs.

Zhang, Xiaoming; Tai, Daniel; Pforsich, Hugh; Lin, Vernon W

This is a reevaluation of registered nurse (RN) supply and demand from 2016 to 2030 using a previously published work forecast model and grading methodology with more recent workforce data. There will be a shortage of 154 018 RNs by 2020 and 510 394 RNs by 2030; the South and West regions will have higher shortage ratios than Northeast and Midwest regions. This reflects a nearly 50% overall improvement when compared with the authors' prior study, and the low-performing states have improved from 18 "D" and 12 "F" grades as published earlier to 13 "D" and 1 "F" in this study. Although progress has been made, efforts to foster the pipelines for improving the nursing workforce need to be continued.

A lower BMI has been reported among consumers of organic foods, but this relationship has never been examined in a prospective design study. Our aim was to prospectively investigate the association between frequency of organic food consumption and weight change. We analysed data from 62 224 participants of the NutriNet-Santé cohort (78 % women, mean age=45 years) with information on consumption frequency of organic foods, dietary intake and repeated anthropometric data. For sixteen products, participants reported their consumption frequency of labelled organic foods (never, occasionally, most of the time). An organic score (OS) with a maximum of thirty-two points was computed. The associations of the OS (modeled as quartiles (Q)) with change in BMI during follow-up (on average 3·1 years) and with the risk of overweight and obesity were estimated by ANCOVA and multivariable logistic regression. A lower BMI increase was observed across quartiles of the OS (mean difference Q4 v. Q1=-0·16 (95 % CI -0·32, -0·01). An increase in the OS was associated with a lower risk of overweight and obesity (among non-overweight and non-obese participants at inclusion): OR for Q4 v. Q1 were 0·77 (95 % CI 0·68, 0·86) and 0·69 (95 % CI 0·58, 0·82), respectively. Concerning obesity risk, the association was stronger among participants with higher adherence to nutritional guidelines. This study supports a strong protective role of consumption frequency of organic foods with regard to the risk of overweight and obesity that depends on overall dietary quality. Upon confirmation, these results may contribute to fine-tune nutritional guidelines by accounting for farming practices in food production.

Food irradiation nears commercial development

International Nuclear Information System (INIS)

1981-01-01

One person out of eight in the world today suffers from chronic undernourishment. This problem is likely to get worse as the world's population doubles during the next thirty to forty years. Since about 25% or more of our harvested food is lost due to various kinds of wastage and spoilage, food preservation is no less important than food production. To supply the world's demand for food, it is more reasonable to conserve what is produced than to produce more to compensate for subsequent losses. Thus, it is obvious that all methods of preserving food and agricultural produce should be examined to see if their use might alleviate the world's food shortage, and that to develop better and safer techniques of food preservation will improve food supplies. Food preservation is an ever greater problem for the developing countries, not only because of their chronic problems of undernourishment, but also because most of them are in tropical or sub-tropical regions where food spoilage is rapid. The IAEA and the Food and Agriculture Organization (FAO) held a symposium on food irradiation at Colombo in Sri Lanka. The symposium paid special attention to the use of food irradiation in preserving tropical fruits as well as fish and fish products. It also examined the cost of the food irradiation process and compared it with those of conventional processes. Food irradiation is one field in which advance is most likely to be achieved through international co-operation. This co-operation has been supported by the IAEA and FAO in a number of ways. During the last 15 years three previous symposia (Karlsruhe, 1966; Bombay, 1972; Wageningen, 1977), numerous panel meetings, and training courses, have been held on this subject and many nations' food irradiation projects have been supported by technical assistance and co-ordinated research programmes

Many questions must be considered with regard to consuming food, including when to eat, what to eat and how much to eat. Although eating is often thought to be a homeostatic behaviour, little evidence exists to suggest that eating is an automatic response to an acute shortage of energy. Instead, food intake can be considered as an integrated response over a prolonged period of time that maintains the levels of energy stored in adipocytes. When we eat is generally determined by habit, convenience or opportunity rather than need, and meals are preceded by a neurally-controlled coordinated secretion of numerous hormones that prime the digestive system for the anticipated caloric load. How much we eat is determined by satiation hormones that are secreted in response to ingested nutrients, and these signals are in turn modified by adiposity hormones that indicate the fat content of the body. In addition, many nonhomeostatic factors, including stress, learning, palatability and social influences, interact with other controllers of food intake. If a choice of food is available, what we eat is based on pleasure and past experience. This article reviews the hormones that mediate and influence these processes.
The past and future of food stocks

Laio, Francesco; Ridolfi, Luca; D’Odorico, Paolo

2016-01-01

Human societies rely on food reserves and the importation of agricultural goods as means to cope with crop failures and associated food shortage. While food trade has been the subject of intensive investigations in recent years, food reserves remain poorly quantified. It is unclear how food stocks are changing and whether they are declining. In this study we use food stock records for 92 products to reconstruct 50 years of aggregated food reserves, expressed in caloric equivalent (kcal), at the regional and global scales. A detailed statistical analysis demonstrates that the overall regional and global per-capita food stocks are stationary, challenging a widespread impression that food reserves are shrinking. We develop a statistically-sound stochastic representation of stock dynamics and take the stock-halving probability as a measure of the natural variability of the process. We find that there is a 20% probability that the global per-capita stocks will be halved by 2050. There are, however, some strong regional differences: Western Europe and the region encompassing North Africa and the Middle East have smaller halving probabilities and smaller per-capita stocks, while North America and Oceania have greater halving probabilities and greater per-capita stocks than the global average. Africa exhibits low per-capita stocks and relatively high probability of stock halving by 2050, which reflects a state of higher food insecurity in this continent. (letter)
Present status and prospects of food irradiation in France

Following the conclusions of the JEFCI (Joint FAO/IAEA/WHO Expert Committee on whole someness of Irradiated Food), CEA (French Atomic Energy Commission) was required by the regulatory committees, in 1981-82, to present a white book on the whole someness of irradiated foods. Following the approval of this white book it was decided to not modify hastily the current regulation of 1970; but to lighten the content of the file of request for authorization by removing its part related to toxicological evidences. This liberalization of procedure has encouraged industrial projects. A large effort of development is initiated and taken in charge locally. The CEA has very important responsabilities in this national effort of development of food irradiation. Three new designs for gamma industrial irradiators were recently improved in France specifically in view of food irradiation, beside the other more conventional designs of carrier and pallet irradiators, already available and well known. The presently available accelerators are not well fitted to food irradiation; the penetration of electrons which are produced is not high enough for food products. A french company, CGR-MeV, recently developed a linear accelerator of 10 MeV and 10 Kw, which appears very attractive

Prospect of commercialization of food irradiation in Indonesia

Hilmy, N.

As a tropical country, the ambient temperature and humidity are high in Indonesia, accordingly foods are apt to be spoiled. Although the production of some important food crops increased from 1986 to 1988, the level of postharvest loss of the crops was also high. The loss was caused mostly by the lack of technological improvement in preservation, processing and distribution system. The export of Indonesian typical tropical commodities increased from 1986 to 1988, but sometimes a part of the commodities was detained by the importing countries since the quality did not meet the requirement. The development of new technologies such as radiation technology is necessary. The limited volume of spices and herbal tea has been irradiated for commercial purpose since 1987. Indonesia has approved the food irradiation technology for commercial purpose in December, 1987. But due to the limited capacity of the existing irradiation facility, the volume of irradiation cannot be increased. At present, there are two irradiation facilities available, the batch type irradiator for foods and latex irradiator. The information transfer for facilitating public acceptance and the barriers and constraints are discussed. (K.I.)
Investment Attractiveness of Food Industries in Ukraine

2017-02-01

Full Text Available Effective investment is a factor for long-term company development. As enhancement of investment attractiveness is a required condition for economic growth and improvement of living standards, it needs to be on the agenda at government and company level. The article’s objective is to study investment attractiveness of food industries in Ukraine over 2012–2015. Investment attractiveness of food industries can be measured by indicators of liquidity, financial sustainability, and profit rate. Basically, food industries in Ukraine are attractive for investment, which is demonstrated by assessment of the financial indicators. The investment attractiveness worsened slightly in 2015 compared with 2014. The essential problems faced by food industries are shortage of internal funds and negative profit rate of all the activities, assets and own capital. Official statistical data and software package SPSS are used to build the dendrogram, allowing for dividing food industries by level of investment attractiveness into three groups: industries with high, medium and low level of investment attractiveness. It is found that meat industry is the one with the highest level of investment attractiveness. Also, investors should look positively at food-canning industry, oil and animal fat industry, flour-milling industry, starch and starch products industry, and other foods industry.

Objective To examine whether baseline chronic stress, morning cortisol, and other appetite-related hormones (leptin, ghrelin, and insulin) predict future weight gain and food cravings in a naturalistic longitudinal 6-month follow-up study. Methods A prospective community cohort of three hundred and thirty-nine adults (age=29.1± 9.0 years; BMI=26.7±5.4 kg/m2; 56.9% female; 70.2% White) completed assessments at baseline and 6-month follow-up. Fasting blood draws were used to assess cortisol and other appetite-related hormones levels at baseline. At baseline and follow-up, body weight was measured and the Cumulative Adversity Interview and Food Craving Inventory were administered. Data were analyzed using linear mixed models adjusting for demographic and clinical covariates. Results Over the 6-month period, 49.9% of the sample gained weight. Food cravings and chronic stress decreased over 6 months (psfood cravings at 6 months (p=0.04). Furthermore, higher cortisol, insulin, and chronic stress were each predictive of greater future weight gain (psfood cravings and reward-driven eating behaviors. Studies are needed that examine the utility of stress reduction methods for normalizing disrupted cortisol responses and preventing future weight gain. PMID:28349668
Common methodologies in the evaluation of food allergy: pitfalls and prospects of food allergy prevalence studies.

Science.gov (United States)

Shu, Shang-an; Chang, Christopher; Leung, Patrick S C

2014-06-01

Global and regional studies on the prevalence of food allergies are plagued by inconsistent methodologies, variations in interpretation of results, and non-standardized study design. Hence, it becomes difficult to compare the prevalence of food allergies in different communities. This information would be useful in providing critical data that will enhance research to elucidate the nature of food allergies, and the role of gene-environment interactions in the sensitization of children and adults to foods. Testing methodologies range from questionnaires to objective in vitro and in vivo testing, to the gold standard, double-blind placebo-controlled food challenge (DBPCFC). Although considered the most accurate and reliable method in detecting the prevalence of food allergy, DBPCFC is not always practical in epidemiological studies of food allergy. On the other hand, multiple logistic regression studies have been done to determine predictability of the outcome of food challenges, and it appears that skin prick testing and in vitro-specific serum IgE are the best predictors. Future studies directed towards confirming the validity of these methods as well as developing algorithms to predict the food challenge outcomes are required, as they may someday become accessory tools to complement DBPCFC.

Drug shortages have been identified as a public health problem in an increasing number of countries. This can negatively impact on the quality and efficiency of patient care, as well as contribute to increases in the cost of treatment and the workload of health care providers. Shortages also raise ethical and political issues. The scientific evidence on drug shortages is still scarce, but many lessons can be drawn from cross-country analyses. The objective of this study was to characterize, compare, and evaluate the current systemic measures and legislative and organizational frameworks aimed at preventing or mitigating drug shortages within health care systems across a range of European and Western Asian countries. The study design was retrospective, cross-sectional, descriptive, and observational. Information was gathered through a survey distributed among senior personnel from ministries of health, state medicines agencies, local health authorities, other health or pharmaceutical pricing and reimbursement authorities, health insurance companies and academic institutions, with knowledge of the pharmaceutical markets in the 28 countries studied. Our study found that formal definitions of drug shortages currently exist in only a few countries. The characteristics of drug shortages, including their assortment, duration, frequency, and dynamics, were found to be variable and sometimes difficult to assess. Numerous information hubs were identified. Providing public access to information on drug shortages to the maximum possible extent is a prerequisite for performing more advanced studies on the problem and identifying solutions. Imposing public service obligations, providing the formal possibility to prescribe unlicensed medicines, and temporary bans on parallel exports are widespread measures. A positive finding of our study was the identification of numerous bottom-up initiatives and organizational frameworks aimed at preventing or mitigating drug shortages. The

Full Text Available Abstract Background Little is known about the impact of the recent varicella vaccine shortage. To assess the temporal trend in varicella vaccine administration before 18 and 24 months of age in a community cohort of children prior to, during and after the recent varicella vaccine shortage. And to compare the temporal trends in varicella vaccinations to trends of an older, more widely accepted vaccine, the MMR. Methods Community population-based birth cohorts were identified who were eligible for the varicella vaccination before, during and after the 2001 to 2002 varicella vaccine shortage. Only children (84% of all who remained in the community through their second birthday were included. For each child in the cohort, the medical records and immunization registry records from both medical facilities in the county were reviewed to identify the dates and sites for all varicella immunizations given. In addition to varicella immunizations, the dates of all MMR vaccinations were recorded. Additional data abstracted included the child's birth date, gender and dates of any recognized cases of chickenpox up through age 24 months. Results Of the 2,512 children in the birth cohorts, 50.8% were boys. In the three cohorts combined, 81.1% of the boys and 79.3% of the girls (p = 0.30 received the varicella vaccine by age 24 months. The pre-shortage community rate of varicella immunization was 79.7% by 24 months of age. During the varicella vaccine shortage, the rate of varicella immunization by 24 months fell to 77.2%. Only 6 additional children received a "catch-up" immunization by 36 months of age. In the post shortage period the community 24-month immunization rate rebounded to a level higher than the pre-shortage rate 84.0%. During the almost three years of observation, the MMR immunization rate by age 24 months was constant (87%. Conclusion The varicella shortage was associated with an immediate drop in the 24-month varicella immunizations rate but
Food irradiation: contributions to public health in developing countries

It may be seen that with advent of the green revolution, the per capita availability of food has shown an increase during the past decade, although population increase during the period has been significant. Currently, the gap between estimated requirement and availability is small and gives the hope that the country can be self-sufficient in the near future. The national averages often do not tell the full story as economic factors lead to uneven distribution of total food supplies. The shortages are more severely felt by the poorer segments as they are economically unable to demand their full share; thus, economically weaker sections of most developing nations live in a chronic state of near famine. Food irradiation is one of these existing technologies. It is a physical method that can be used to preserve food from microbial and insect damage and infection, as well as from physiological deterioration. In other words, this method can extend the storage life of food considerably without noticeable change of the properties of the food commodity. The impact of food irradiation can be very great especially because of its contribution to the hygienization of food

In many countries hydropower constitutes a large share of the electricity producing capacity. In the earlier regulated electricity markets, production capacities exceeded demand due to security of supply concerns. The present deregulated markets base investments upon profitability alone, and security of supply issues are claimed to be less important. Market operators trust the pricing mechanism in competitive markets to clear. Then low inflow constitutes a less problem. Several markets, both under regulated and deregulated regimes, have faced serious droughts. Some of them have experienced problems with market clearance (Chile, Brazil, California) while other markets functioned well (The Nordic market). Important features to the market response are the flexibility of demand, the pattern of inflow shortage, the storage capacities, the possibility of trade between regions with different production technologies, and the market design and concentration. We apply an empirical based market model to simulate the effects under two inflow shortage scenarios in an international market with combined hydro and thermal capacities and restricted transmission capacities. We compare the scenarios with actual events and show that the model and the real market outcome are comparable. The simulations do not reveal any problems with the functioning of the market, which should calm down the anxiousness about security of supply in deregulated markets with stochastic energy supply

2009-01-01

Food security is an important issue that is of concern for all countries around the world. There are many factors which may cause food insecurity including increasing demand, shortage of supply, trade condition, another countries' food policy, lack of money, high food and oil prices, decelerating productivity, speculation, etc. The food self-sufficiency ratio of Taiwan is only 30.6% weighted by energy in 2007. Total agriculture imports and cereals have increased significantly due to the expansion of livestock and fishery industries and improve living standard. The agriculture sector of Taiwan is facing many challenges, such as: low level of food self-sufficiency, aging farmers, large acreage of set-aside farmlands, small scale farming, soaring price of fertilizers, natural disasters accelerated by climate change, and rapid changes in the world food economy. To cope with these challenges, the present agricultural policy is based on three guidelines: "Healthfulness, Efficiency, and Sustainability." A program entitled "Turning Small Landlords into Large Tenants" was launched to make effective use of idle lands. Facing globalization and the food crisis, Taiwan will secure stable food supply through revitalization of its set-aside farmlands and international markets, and provide technical assistance to developing countries, in particular for staple food crops.
Stakeholders' Perceptions on Shortage of Healthcare Workers in Primary Healthcare in Botswana: Focus Group Discussions.

Full Text Available An adequate health workforce force is central to universal health coverage and positive public health outcomes. However many African countries have critical shortages of healthcare workers, which are worse in primary healthcare. The aim of this study was to explore the perceptions of healthcare workers, policy makers and the community on the shortage of healthcare workers in Botswana.Fifteen focus group discussions were conducted with three groups of policy makers, six groups of healthcare workers and six groups of community members in rural, urban and remote rural health districts of Botswana. All the participants were 18 years and older. Recruitment was purposive and the framework method was used to inductively analyse the data.There was a perceived shortage of healthcare workers in primary healthcare, which was believed to result from an increased need for health services, inequitable distribution of healthcare workers, migration and too few such workers being trained. Migration was mainly the result of unfavourable personal and family factors, weak and ineffective healthcare and human resources management, low salaries and inadequate incentives for rural and remote area service.Botswana has a perceived shortage of healthcare workers, which is worse in primary healthcare and rural areas, as a result of multiple complex factors. To address the scarcity the country should train adequate numbers of healthcare workers and distribute them equitably to sufficiently resourced healthcare facilities. They should be competently managed and adequately remunerated and the living conditions and rural infrastructure should also be improved.
Food security and environmental degradation in northern Nigeria: demographic perspectives.

Science.gov (United States)

Lockwood, M

1991-07-01

The Malthusian controversy about the causes of environmental change and food insecurity in Hausaland in northern Nigeria is examined. The argument is irresolvable based on available data at the macro level. The individual and household level are appropriate for answering the question about how high density populations survive on a savannah. To understand population pressure in Hausaland, it is important to read Malthus very carefully and to understand the existing demographic structure in which economic and kinship relations support high fertility even where land is scarce. Demographic responses vary with economic strata. Policies ignore individual level differences. Since 1953, the densely populated areas of Sokoto, Katsina, Zaria, and Kano have spread in an area that is largely dry with a moderate-to-high risk of desertification. Food insecurity exists not only in times of drought, but also annually in the form of chronic shortages of staples for poor farmers. Average land holdings/capita have become smaller. Population pressure has also contributed to shifts in land use. Food prices have increased. Possible explanations include 1) the drought and the oil boom have a greater impact on environmental change and food insecurity and rural Hausa farmers have responded by raising yields, managing tree resources, and practicing soil conservation and 2) an independent source of income from non-agricultural activities is an essential part of the economy. The relationship among population pressure, land shortage, and food insecurity is complex. It is inaccurate to label Hausa as subsistence farmers, when trading in grain is an important enterprise. The role that commercialization of agriculture plays in food insecurity is discussed. Malthusian disaster is not imminent. The proximate determinants of fertility, birth spacing practices and infertility, should lead to high fertility rates, but in this case they do not. Determinants responsive to economic factors tend to be
Weather patterns, food security and humanitarian response in sub-Saharan Africa.

Although considerable achievements in the global reduction of hunger and poverty have been made, progress in Africa so far has been very limited. At present, a third of the African population faces widespread hunger and chronic malnutrition and is exposed to a constant threat of acute food crisis and famine. The most affected are rural households whose livelihood is heavily dependent on traditional rainfed agriculture. Rainfall plays a major role in determining agricultural production and hence the economic and social well being of rural communities. The rainfall pattern in sub-Saharan Africa is influenced by large-scale intra-seasonal and inter-annual climate variability including occasional El Niño events in the tropical Pacific resulting in frequent extreme weather event such as droughts and floods that reduce agricultural outputs resulting in severe food shortages. Households and communities facing acute food shortages are forced to adopt coping strategies to meet the immediate food requirements of their families. These extreme responses may have adverse long-term, impacts on households' ability to have sustainable access to food as well as the environment. The HIV/AIDS crisis has also had adverse impacts on food production activities on the continent. In the absence of safety nets and appropriate financial support mechanisms, humanitarian aid is required to enable households effectively cope with emergencies and manage their limited resources more efficiently. Timely and appropriate humanitarian aid will provide households with opportunities to engage in productive and sustainable livelihood strategies. Investments in poverty reduction efforts would have better impact if complemented with timely and predictable response mechanisms that would ensure the protection of livelihoods during crisis periods whether weather or conflict-related. With an improved understanding of climate variability including El Niño, the implications of weather patterns for the food
Food  Security  in  Iceland

Alyson J.K. Bailes

2011-12-01

Full Text Available The concept of food security applies in both poor and rich societies and concerns the steady availability of food in the right quantity and quality, at the right price. Globally, policies to assure it remain confused and world food prices are rising. Despite large exports of fish, Iceland produces only around half of its inhabitants’ nutritional needs and relies significantly on imports, also for food production inputs like fodder and seeds. Icelandic supplies are affected by oligopoly in the retail market, and could be put at risk by events in other security dimensions ranging from natural disasters and infrastructure failures to terrorism, neighbouring conflicts and other people’s shortages. Icelandic farmers have used the terminology of ‘food security’ to press their claims for more home-grown production, and more recently also in their campaign against EU membership. The general public however shows little sign of security-awareness in this field. The government possesses suitable non-military security frameworks to address food-related risks and has initiated useful, general and specific, studies. Yet it has not developed a strategy or contingency plan for food security, even following the lessons of the 2008 economic crash and 2010-2011 eruptions. Suitable remedies would include larger emergency stocks and a range of measures to reduce vulnerability and improve resilience in crises. Above all, Iceland needs a balanced and open policy-making process to decide what its general future strategy should be as a food-producing and -importing nation. Food security could then be more precisely defined and pursued with the aim of minimizing threats and risks to that agreed vision.

Manufacturing is the bridge between research and patient: without product, there is no clinical outcome. Shortage has a variety of causes, in this paper we analyse only causes related to manufacturing technology and we use shortage as a paradigm highliting the relevance of Pharmaceutical Technology. Product and process complexity and capacity issues are the main challenge for the Pharmaceutical Industry Supply chain. Manufacturing Technology should be acknowledged as a R&D step and as a very important matter during University degree in Pharmacy and related disciplines, promoting collaboration between Academia and Industry, measured during HTA step and rewarded in terms of price and reimbursement. The above elements are not yet properly recognised, and manufacturing technology is taken in to consideration only when a shortage is in place. In a previous work, Panzitta et al. proposed to perform a full technology assessment at the Health Technological Assessment stage, evaluating three main technical aspects of a medicine: manufacturing process, physicochemical properties, and formulation characteristics. In this paper, we develop the concept of manufacturing appraisal, providing a technical overview of upcoming challenges, a risk based approach and an economic picture of shortage costs. We develop also an overall quality concept, not limited to GMP factors but broaden to all elements leading to a robust supply and promoting technical innovation. Copyright © 2016 Elsevier B.V.

The objective of the present study was to investigate the relationship between total and subtypes of bacterial fermented food intake (dairy products, cheese, vegetables and meat) and mortality due to all causes, total cancer and CVD. From the European Prospective Investigation into Cancer and Nutrition-Netherlands cohort, 34 409 Dutch men and women, aged 20-70 years who were free from CVD or cancer at baseline, were included. Baseline intakes of total and subtypes of fermented foods were measured with a validated FFQ. Data on the incidence and causes of death were obtained from the national mortality register. Cox proportional hazards models were used to analyse mortality in relation to the quartiles of fermented food intake. After a mean follow-up of 15 (sd 2·5) years, 2436 deaths occurred (1216 from cancer and 727 from CVD). After adjustment for age, sex, total energy intake, physical activity, education level, hypertension, smoking habit, BMI, and intakes of fruit, vegetables and alcohol, total fermented food intake was not found to be associated with mortality due to all causes (hazard ratio upper v. lowest quartile (HR(Q4 v. Q1)) 1·00, 95% CI 0·88, 1·13), cancer (HR(Q4 v. Q1) 1·02, 95% CI 0·86, 1·21) or CVD (HR(Q4 v. Q1) 1·04, 95 % CI 0·83, 1·30). Bacterial fermented foods mainly consisted of fermented dairy foods (78 %) and cheese (16%). None of the subtypes of fermented foods was consistently related to mortality, except for cheese which was moderately inversely associated with CVD mortality, and particularly stroke mortality (HR(Q4 v. Q1) 0·59, 95% CI 0·38, 0·92, P trend= 0·046). In conclusion, the present study provides no strong evidence that intake of fermented foods, particularly fermented dairy foods, is associated with mortality.

This paper summarizes studies on the water demand and supply problems in Indonesia in the last few years. During the dry season in 1990, it was reported that lack of fresh drinking water in Java and Bali amounted to 2.4 x 10 6 ton/month. Since Indonesia consists of more than 13,000 islands, more problems are faced by other islands. The studies are focused on certain regions (groups of islands) which may have a potential for using a floating desalination facility. Water reservoirs in each island and delivery systems from the floating desalination facilities need to be assessed to see the prospective uses of the systems. Cheap, self-forgiving and easily operated systems, using transportable ship mounted desalination facilities, may be required as a solution to the water supply shortages for these islands. Conclusions based on current problems in water demand and supply and comments on the prospective future market using floating desalination facilities in Indonesia are also given.

Food waste and food processing wastes which are abundant in nature and rich in carbon content can be attractive renewable substrates for sustainable biohydrogen production due to wide economic prospects in industries. Many studies utilizing common food wastes such as dining hall or restaurant waste and wastes generated from food processing industries have shown good percentages of hydrogen in gas composition, production yield and rate. The carbon composition in food waste also plays a crucial role in determining high biohydrogen yield. Physicochemical factors such as pre-treatment to seed culture, pH, temperature (mesophilic/thermophilic) and etc. are also important to ensure the dominance of hydrogen-producing bacteria in dark fermentation. This review demonstrates the potential of food waste and food processing waste for biohydrogen production and provides a brief overview of several physicochemical factors that affect biohydrogen production in dark fermentation. The economic viability of biohydrogen production from food waste is also discussed. Copyright © 2013 Elsevier Ltd. All rights reserved.
Future Water Scarcity and Potential Effects on Food Production under Climate Change in the Yellow River Basin

Increasing population and socio-economic development have put great pressure on water resources of the Yellow River Basin. The anticipated climate and socio-economic changes may further increase water stress. In this study, we assess water scarcity under climate change and various socio-economic pathways with an emphasis on the impact of water shortages on food production. The water demands in the 21st century are projected under the new developed Shared Socio-economic Pathways (SSPs). The renewable water supply is estimated from the climate projections under the Representative Concentration Pathways (RCP) 8.5. The agricultural water use is assumed to have the lowest priority of all water consumers when water shortage occurs. The results show that the water demands in domestic and industrial sectors would grow rapidly. As more water resources would be occupied by domestic and industrial sectors, a portion of irrigated land would have to be converted to rain-fed agriculture which would lead to more than a reduction in food production under various socio-economic pathways. This study highlights the links between water, food and ecosystems in a changing environment and suggests that trade-offs should be considered when developing regional adaptation strategies.
Food irradiation: the 'experts' choice

International Nuclear Information System (INIS)

Watts, P.

1990-01-01

The UK Government has decided to lift the ban on food irradiation. The proponents of food irradiation claim it is an effective and safe means of preserving food, at minimum risk to the public. However, the prospect of irradiated food being on the shelves has created considerable opposition from environmental, consumer, public health groups and trade unions. The long list of unanswered health and safety questions means the public could be exposed to a whole new range of risks. The consumer is justified as saying ''if food has to be irradiated, what was wrong with it, good food does not need irradiating''. The answer to food contamination is improved hygiene and training in farm, factory and shop. (author)

Bogor regency consists of 40 districts, 23 are prone tonatural disasters. Klapanunggal district is listed in 10 districts declared as most vulnerable to natural disasters. Natural disasters could lead to loss of property and infrastructure damage and will affect the food security in the region. Food shortages is one example of the condition which causes food insecurity. The aim of this research is to analyze the government's food security strategy in anticipation of disaster with a case study of food insecurity in Klapanunggal district. The analysis suggested that; 1) FSVA is an appropriate program to identify food shortage areas, 2) Food Shortage Relief Program (Program Penanganan Daerah Rawan Pangan-PDRP) is the optimal efforts in reducing food shortages in the region, 3)The mismatch between FSVA indicators and Food Shortage Relief Program makes Klapanunggal district difficult in achievingfree status food-shortage. Based on the analysis, it is suggested that the implementation of Food Shortages Relief Program could be carried out based on the priority issues and implemented with integrated coordination and assistance among stakeholders. Such priority issues, integrated coordination and assistance are fully analyzed in this study.

Shortage of physicians particularly in specialty levels is considered as an important issue in Iran health system. Thus, in an uncertain environment, long-term planning is required for health professionals as a basic priority on a national scale. This study aimed to estimate the number of required neurosurgeons using system dynamic modeling. System dynamic modeling was applied to predict the gap between stock and number of required neurosurgeons in Iran up to 2020. A supply and demand simulation model was constructed for neurosurgeons using system dynamic approach. The demand model included epidemiological, demographic, and utilization variables along with supply model-incorporated current stock of neurosurgeons and flow variables such as attrition, migration, and retirement rate. Data were obtained from various governmental databases and were analyzed by Vensim PLE Version 3.0 to address the flow of health professionals, clinical infrastructure, population demographics, and disease prevalence during the time. It was forecasted that shortage in number of neurosurgeons would disappear at 2020. The most dominant determinants on predicted number of neurosurgeons were the prevalence of neurosurgical diseases, the rate for service utilization, and medical capacity of the region. Shortage of neurosurgeons in some areas of the country relates to maldistribution of the specialists. Accordingly, there is a need to reconsider the allocation system for health professionals within the country instead of increasing the overall number of acceptance quota in training positions.

To examine the association between fast-food consumption, diet quality and body weight in a community sample of working adults. Cross-sectional and prospective analysis of anthropometric, survey and dietary data from adults recruited to participate in a worksite nutrition intervention. Participants self-reported frequency of fast-food consumption per week. Nutrient intakes and diet quality, using the Healthy Eating Index-2010 (HEI-2010), were computed from dietary recalls collected at baseline and 6 months. Metropolitan medical complex, Minneapolis, MN, USA. Two hundred adults, aged 18-60 years. Cross-sectionally, fast-food consumption was significantly associated with higher daily total energy intake (β=72·5, P=0·005), empty calories (β=0·40, P=0·006) and BMI (β=0·73, P=0·011), and lower HEI-2010 score (β=-1·23, P=0·012), total vegetables (β=-0·14, P=0·004), whole grains (β=-0·39, P=0·005), fibre (β=-0·83, P=0·002), Mg (β=-6·99, P=0·019) and K (β=-57·5, P=0·016). Over 6 months, change in fast-food consumption was not significantly associated with changes in energy intake or BMI, but was significantly inversely associated with total intake of vegetables (β=-0·14, P=0·034). Frequency of fast-food consumption was significantly associated with higher energy intake and poorer diet quality cross-sectionally. Six-month change in fast-food intake was small, and not significantly associated with overall diet quality or BMI.

Their linear, and increasingly globalised, structure assumes that the Earth has an endless supply of natural resources at one end, and a limitless capacity to absorb waste and pollution at the other. Our continued reliance on these industrial systems is pushing the world into a vicious cycle of food shortages, climate chaos, famine and disaster. How can we transform our production models for food, energy and water to deliver lower ecological and social footprints? The answer lies in using circular models that mimic natural systems to reduce both external inputs and waste. Case studies from across the world show that circular production systems can and do work for sustainability and equity. But these remain largely isolated examples. Upscaling successful circular systems for food, energy, water and waste management requires policymakers to act on seven fronts.

Many OECD countries are faced with the considerable challenge of a physician shortage. This paper investigates the strategies that OECD governments adopt and determines whether these policies effectively address these medical shortages. Due to the amount of time medical training requires, it takes longer for an expansion in medical school capacity to have an effect than the recruitment of foreign-trained physicians. Using data obtained from the OECD (2014) and Bhargava et al. (2011), we constructed a unique country-level panel dataset that includes annual data for 17 OECD countries on physician shortages, the number of medical school graduates and immigration and emigration rates from 1991 to 2004. By calculating panel fixed-effect estimates, we find that after a period of medical shortages, OECD governments produce more medical graduates in the long run but in the short term, they primarily recruit from abroad; however, at the same time, certain practising physicians choose to emigrate. Simulation results show the limits of recruiting only abroad in the long term but also highlight its appropriateness for the short term when there is a recurrent cycle of shortages/surpluses in the labour supply of physicians (pig cycle theory).

The objective of this study was to derive food-based dietary guidelines for the Dutch population. The dietary guidelines are based on 29 systematic reviews of English language meta-analyses in PubMed summarizing randomized controlled trials and prospective cohort studies on nutrients, foods and food patterns and the risk of 10 major chronic diseases: coronary heart disease, stroke, heart failure, diabetes, breast cancer, colorectal cancer, lung cancer, chronic obstructive pulmonary disease, dementia and depression. The committee also selected three causal risk factors for cardiovascular diseases or diabetes: systolic blood pressure, low-density lipoprotein cholesterol and body weight. Findings were categorized as strong or weak evidence, inconsistent effects, too little evidence or effect unlikely for experimental and observational data separately. Next, the committee selected only findings with a strong level of evidence for deriving the guidelines. Convincing evidence was based on strong evidence from the experimental data either or not in combination with strong evidence from prospective cohort studies. Plausible evidence was based on strong evidence from prospective cohort studies only. A general guideline to eat a more plant food-based dietary pattern and limit consumption of animal-based food and 15 specific guidelines have been formulated. There are 10 new guidelines on legumes, nuts, meat, dairy produce, cereal products, fats and oils, tea, coffee and sugar-containing beverages. Three guidelines on vegetables, fruits, fish and alcoholic beverages have been sharpened, and the 2006 guideline on salt stayed the same. A separate guideline has been formulated on nutrient supplements. Completely food-based dietary guidelines can be derived in a systematic and transparent way.
Credit financing for deteriorating imperfect quality items with allowable shortages

2016-01-01

Full Text Available The outset of new technologies, systems and applications in manufacturing sector has no doubt lighten up our workload, yet the chance causes of variation in production system cannot be eliminated completely. Every produced/ordered lot may have some fraction of defectives which may vary from process to process. In addition the situation is more susceptible when the items are deteriorating in nature. However, the defective items can be secluded from the good quality lot through a careful inspection process. Thus, a screening process is obligatory in today’s technology driven industry which has the customer satisfaction as its only motto. Moreover, in order to survive in the current global markets, credit financing has been proven a very influential promotional tool to attract new customers and a good inducement policy for the retailers. Keeping this scenario in mind, the present paper investigates an inventory model for a retailer dealing with imperfect quality deteriorating items under permissible delay in payments. Shortages are allowed and fully backlogged. This model jointly optimizes the order quantity and shortages by maximizing the expected total profit. A mathematical model is developed to depict this scenario. Results have been validated with the help of numerical example. Comprehensive sensitivity analysis has also been presented.

Integrated food security covers three aspects: food quantity security, food quality security, and sustainable food security. Because sustainable food security requires that food security must be compatible with sustainable development, the risk assessment of sustainable food security is becoming one of the most important issues. This paper mainly focuses on the characteristics of sustainable food security problems in the major grain-producing areas in China. We establish an index system based on land resources and eco-environmental conditions and apply a dynamic assessment method based on status assessments and trend analysis models to overcome the shortcomings of the static evaluation method. Using fuzzy mathematics, the risks are categorized into four grades: negligible risk, low risk, medium risk, and high risk. A case study was conducted in one of China's major grain-producing areas: Dongting Lake area. The results predict that the status of the sustainable food security in the Dongting Lake area is unsatisfactory for the foreseeable future. The number of districts at the medium-risk range will increase from six to ten by 2015 due to increasing population pressure, a decrease in the cultivated area, and a decrease in the effective irrigation area. Therefore, appropriate policies and measures should be put forward to improve it. The results could also provide direct support for an early warning system-which could be used to monitor food security trends or nutritional status so to inform policy makers of impending food shortages-to prevent sustainable food security risk based on some classical systematic methods. This is the first research of sustainable food security in terms of risk assessment, from the perspective of resources and the environment, at the regional scale.

The harpacticoid copepod Nitocra spinipes has become a popular model species for toxicity testing over the past few decades. However, the combined influence of temperature and food shortage, two climate change-related stressors, has never been assessed in this species. Consequently, effects of three temperatures (15, 20 and 25°C) and six food regimes (between 0 and 5 × 105 algal cells/mL) on the life cycle of N. spinipes were examined in this study. Similarly to other copepod species, development times and brood sizes decreased with rising temperatures. Mortality was lowest in the 20°C temperature setup, indicating a close-by temperature optimum for this species. Decreasing food concentrations led to increased development times, higher mortality and a reduction in brood size. A sex ratio shift toward more females per male was observed for increasing temperatures, while no significant relationship with food concentration was found. Temperature and food functions for each endpoint were integrated into an existing individual-based population model for N. spinipes which in the future may serve as an extrapolation tool in environmental risk assessment. The model was able to accurately reproduce the experimental data in subsequent verification simulations. We suggest that temperature, food shortage, and potentially other climate change-related stressors should be considered in environmental risk assessment of chemicals to account for non-optimal exposure conditions that may occur in the field. Furthermore, we advocate combining in vivo bioassays with population modeling as a cost effective higher tier approach to assess such considerations. PMID:28334000

Food science and technology education has been running since four decades in Nepal. There is a very slow improvement in the profession. The job opportunities have always been threatened by insiders and outsiders. Academic institutions, government agencies, and food industries themselves are responsible for the quality of food science professionals. Novel and practical methods of teaching should be followed. The government and private organizations should facilitate the recruitment of food technologists. Constant prodding needs to be done for the establishment of a Council with more authority that could monitor all bodies associated with food science professionals. PMID:25493177

Biotechnology is providing us with a wide range of options for how we can use agricultural and commercial forestry lands. The cultivation of genetically modified (GM) crops on millions of hectares of lands and their injection into our food chain is a huge global genetic experiment involving all living beings. Considering the fast pace of new advances in production of genetically modified crops, consumers, farmers and policymakers worldwide are challenged to reach a consensus on a clear vision for the future of world food supply. The current food biotechnology debate illustrates the serious conflict between two groups: 1) Agri-biotech investors and their affiliated scientists who consider agricultural biotechnology as a solution to food shortage, the scarcity of environmental resources and weeds and pests infestations; and 2) independent scientists, environmentalists, farmers and consumers who warn that genetically modified food introduces new risks to food security, the environment and human health such as loss of biodiversity; the emergence of superweeds and superpests; the increase of antibiotic resistance, food allergies and other unintended effects. This article reviews major viewpoints which are currently debated in the food biotechnology sector in the world. It also lays the ground-work for deep debate on benefits and risks of Biotech-crops for human health, ecosystems and biodiversity. In this context, although some regulations exist, there is a need for continuous vigilance for all countries involved in producing genetically engineered food to follow the international scientific bio-safety testing guidelines containing reliable pre-release experiments and post-release track of transgenic plants to protect public health and avoid future environmental harm.
Food security and sustainable resource management

Science.gov (United States)

McLaughlin, Dennis; Kinzelbach, Wolfgang

2015-07-01

The projected growth in global food demand until mid-century will challenge our ability to continue recent increases in crop yield and will have a significant impact on natural resources. The water and land requirements of current agriculture are significantly less than global reserves but local shortages are common and have serious impacts on food security. Recent increases in global trade have mitigated some of the effects of spatial and temporal variability. However, trade has a limited impact on low-income populations who remain dependent on subsistence agriculture and local resources. Potential adverse environmental impacts of increased agricultural production include unsustainable depletion of water and soil resources, major changes in the global nitrogen and phosphorous cycles, human health problems related to excessive nutrient and pesticide use, and loss of habitats that contribute to agricultural productivity. Some typical case studies from China illustrate the connections between the need for increased food production and environmental stress. Sustainable options for decreasing food demand and for increasing production include reduction of food losses on both the producer and consumer ends, elimination of unsustainable practices such as prolonged groundwater overdraft, closing of yield gaps with controlled expansions of fertilizer application, increases in crop yield and pest resistance through advances in biotechnology, and moderate expansion of rain fed and irrigated cropland. Calculations based on reasonable assumptions suggest that such measures could meet the food needs of an increasing global population while protecting the environment.
Effects of a power shortage in the Tokyo metropolitan area on awareness of nuclear power generation and power savings behavior

International Nuclear Information System (INIS)

Kitada, Atsuko

2004-01-01

The shutdown of a number of nuclear power stations of the Tokyo Electric Power Company in the summer of 2003 caused a power shortage problem in the Tokyo Metropolitan area. To examine the effects of the power shortage, in September 2003 a survey was conducted in the service areas of the Kansai Electric Power Company (Kansai region) and the Tokyo Electric Power Company (Kanto region). This survey was part of a wider opinion survey begun in 1993 concerning nuclear power generation. The results of the September 2003 survey are as follows: The degree of recognition of the power shortage problem in the Metropolitan area was high, with 40% of respondents in the Kansai region and nearly 70% in the Kanto region understanding that the shortage was caused by the shutdown of several nuclear power station. The overall awareness of nuclear power generation was little affected in both the Kansai and Kanto regions, though the sense of a shortage of the generating capacity had been raised slightly. Once respondents knew about the power shortage problem, they estimated the likelihood of an occurrence of large-scale service interruption to be low, nearly at an even chance, and they had been only slightly worried about it, essentially viewing the problem optimistically. In the Kanto region, where public relations activities for power savings had been actively pursued, the frequency of experiencing exposure to such public relations activities was remarkably higher than in the Kansai region. The relation between exposure to public relations activities for power savings and power savings behavior was analyzed using quantification method II. Analysis results suggest that public relations activities for power savings in the Kanto region had the effect of urging power savings behavior. However, the difference in the rate of putting power savings behavior into practice was small between the Kanto and Kansai regions, indicating that public relation activities for power savings in the Kanto

To assess obesity risk among mothers participating in Community Kitchens and children participating in Glass of Milk (Peru food assistance programs). We analyzed prospective data from the Young Lives study. The exposure consisted in varying degrees of benefit from any of the programs (no participation in any of the programs, program participation for some months, or program participation nearly every month) at baseline (2006-2007). The outcome was overweight and obesity in mothers and children at follow-up (2009-2010). Prevalence of childhood overweight and obesity was 15.5% and 5.1%, respectively; the corresponding figures for mothers were 40.5% and 14.6%. Children exposed nearly every month to the Glass of Milk program had a 65% lower risk of becoming obese compared with children not participating in the program (relative risk [RR] = 0.35; 95% confidence interval [CI] = 0.18, 0.66). Mothers participating frequently in the Community Kitchens program had almost twice the risk of becoming obese compared with those who did not participate (RR = 1.93; 95% CI = 1.18, 3.15). Participating in food assistance programs in Peru was associated with a lower risk of obesity in children and greater risk of obesity in mothers.

Is There a Shortage of Obstetrician-Gynecologists?

Science.gov (United States)

Stonehocker, Jody; Muruthi, Joyce; Rayburn, William F

2017-03-01

Projections of supply and demand for obstetricians-gynecologists suggest a current minimal or modest shortage that will worsen in the future. The US adult female population is expected to increase by more than 20% by 2045 and represents a key driver for increased demand for health care services. The annual number of obstetrician-gynecologists (ob-gyn) residency graduates has increased negligibly, whereas the proportion accepted into fellowships increased steadily, reducing those in general practice. The gradual increase in proportion of ob-gyns who are women coincides with desires for more work-life balance and earlier retirement from clinical practice. As the supply of advanced practice providers of women's health services grows, the need for more ob-gyns could be less to meet the projected demand. Copyright © 2016 Elsevier Inc.

Cao, Shanshan; Gentili, Monica; Griffin, Paul M; Griffin, Susan O; Harati, Pravara; Johnson, Ben; Serban, Nicoleta; Tomar, Scott

Demand for dental care is expected to outpace supply through 2025. The objectives of this study were to determine the extent of pediatric dental care shortages in Georgia and to develop a general method for estimation that can be applied to other states. We estimated supply and demand for pediatric preventive dental care for the 159 counties in Georgia in 2015. We compared pediatric preventive dental care shortage areas (where demand exceeded twice the supply) designated by our methods with dental health professional shortage areas designated by the Health Resources & Services Administration. We estimated caries risk from a multivariate analysis of National Health and Nutrition Examination Survey data and national census data. We estimated county-level demand based on the time needed to perform preventive dental care services and the proportion of time that dentists spend on pediatric preventive dental care services from the Medical Expenditure Panel Survey. Pediatric preventive dental care supply exceeded demand in Georgia in 75 counties: the average annual county-level pediatric preventive dental care demand was 16 866 hours, and the supply was 32 969 hours. We identified 41 counties as pediatric dental care shortage areas, 14 of which had not been designated by the Health Resources & Services Administration. Age- and service-specific information on dental care shortage areas could result in more efficient provider staffing and geographic targeting.
An Agent-based Modeling of Water-Food Nexus towards Sustainable Management of Urban Water Resources

Science.gov (United States)

Esmaeili, N.; Kanta, L.

2017-12-01

Growing population, urbanization, and climate change have put tremendous stress on water systems in many regions. A shortage in water system not only affects water users of a municipality but also that of food system. About 70% of global water is withdrawn for agriculture; livestock and dairy productions are also dependent on water availability. Although researchers and policy makers have identified and emphasized the water-food (WF) nexus in recent decade, most existing WF models offer strategies to reduce trade-offs and to generate benefits without considering feedback loops and adaptations between those systems. Feedback loops between water and food system can help understand long-term behavioral trends between water users of the integrated WF system which, in turn, can help manage water resources sustainably. An Agent-based modeling approach is applied here to develop a conceptual framework of WF systems. All water users in this system are modeled as agents, who are capable of making decisions and can adapt new behavior based on inputs from other agents in a shared environment through a set of logical and mathematical rules. Residential and commercial/industrial consumers are represented as municipal agents; crop, livestock, and dairy farmers are represented as food agents; and water management officials are represented as policy agent. During the period of water shortage, policy agent will propose/impose various water conservation measures, such as adapting water-efficient technologies, banning outdoor irrigation, implementing supplemental irrigation, using recycled water for livestock/dairy production, among others. Municipal and food agents may adapt conservation strategies and will update their demand accordingly. Emergent properties of the WF nexus will arise through dynamic interactions between various actors of water and food system. This model will be implemented to a case study for resource allocation and future policy development.

2018-03-01

The present research aimed to investigate the impact of the physical activity calorie equivalent (PACE) front-of-pack label on consumption, prospective consumption and liking of familiar and unfamiliar discretionary snack foods. In a within-subject randomised design, participants tasted and rated liking (9-point hedonic scale) and prospective consumption (9-point category scale) of four different snack foods with four different labels (i.e. blank, fake, PACE, PACE doubled) and four control snack foods. The twenty snack foods were presented during two 45 min sessions (i.e. ten snack foods per session) which were separated by one week. The amount participants sampled of each snack food was measured. The study was conducted in the Centre for Advanced Sensory Sciences laboratory at Deakin University, Australia. The participants were 153 university students (126 females, twenty-seven males, mean age 24·3 (sd 4·9) years) currently enrolled in an undergraduate nutrition degree at Deakin University. When the PACE label was present on familiar snack foods, participants sampled 9·9 % (22·8 (sem 1·4) v. 25·3 (sem 1·5) g, P=0·03) less than when such label was not present. This was in line with a decreased prospective snack food consumption of 9·1 % (3·0 (sem 0·2) v. 3·3 (sem 0·2) servings, P=0·03). Such pattern was not seen in unfamiliar snacks. The PACE label appears to be a promising way to decrease familiar discretionary snack food consumption in young, health-minded participants.

The European Prospective Investigation into Cancer and Nutrition (EPIC), which has been established in order to investigate the relations between nutrition and cancer, was initiated in 1990 and involves 10 European countries with heterogeneous dietary patterns and differing cancer incidence rates. This manuscript presents the design, recruitment and baseline characteristics of the Prospect-EPIC cohort co-ordinated in Utrecht, The Netherlands. The cohort is based on volunteers recruited among women participating in a regional breast cancer screening program. It comprises of 17,357 subjects aged 50-69 years at enrolment from Utrecht and vicinity, who have consented to participate in the study and its follow-up. Each participant filled out a general questionnaire and a food frequency questionnaire. Participants were also physically examined and have donated a blood sample. Participation rate was 34.5%. Blood samples were donated by most participants (97.5%) and detailed informed consents were obtained from 87.4% of participants. Mean age at enrolment was 57 years. Anthropometric, lifestyle and morbidity characteristics of the cohort population did not differ largely from those of similar study populations in The Netherlands. Based on the Prospect-EPIC population, we intend to conduct prospective total cohort, nested case-control or case-cohort studies, in order to investigate relations between consumption of certain food groups or nutrients and chronic diseases, including hormone dependant cancers such as breast, colon, endometrial and ovary cancers.

Prospects for oil and gas

International Nuclear Information System (INIS)

Laherrere, J.

2011-01-01

It was five years ago, in January 2006, that Futuribles devoted a major special issue (no. 315) to energy prospects and the greenhouse effect. That was already a time of great concern about this question and several articles offered analyses of the gloomy prospects for the development of energy resources and the issues around climate change. Among these, an article by Jean Laherrere outlined the prospects for oil resources, showing the extent to which information in this area was disparate, unreliable and even questionable, being often highly political. As one of the more pessimistic writers on the question, Laherrere reminded us of the imminence of 'peak oil' (the prelude to a decline in global oil production) and the need to re-think our styles of consumption to adapt to a new age in which, as energy becomes scarcer, it will be increasingly expensive. Five years later, Jean Laherrere returns to the columns of Futuribles on the occasion of a new special issue on energy and the climate, to update us on the global prospects for oil and gas production. He begins by recalling how politically slanted and unreliable information in this area can be, depending on its source, the units of measurement employed etc. He stresses, too, that in the view of many experts peak oil was reached in 2006 and the situation is currently plateau-ing, just ahead of a decline in oil production (gradual or sudden, depending on whether measures of economic constraint are implemented). For its part, gas production should peak around 2025-2030. Jean Laherrere specifies what reserves remain, how these are currently exploited and marketed, and the prospects that ensue in the longer term (he also shows how wrong gas-price forecasts have been in the past). As he stresses, in conclusion, with both oil and gas we must be aware that the world does not have infinite resources and, since the alternatives do not allow us, at the moment, to make up for future energy-resource shortages, it is for

to dog dung, an impoverishment of the total richness was observed (from 19 to 9 species) together with an increase of individuals (by 7 times). Dog dung harboured 20% of the current scarab dung beetle fauna of Rome, probably as a consequence of the dog mixed diet, rich in cellulose. Both the communities...... showed a high percentage of tunnellers, probably because of the food shortage and, for dog scats, of the high dehydration rate. A comparison with other Roman scarab communities enhanced that: (1) the change in food resource determined a higher difference in species composition respect to other parameters......The aim of the research was to show how a change in land use influences the structure of a dung beetle assemblage and affect its conservation. In the Pineto Urban Regional Park (Rome), dog dung is the sole food resource currently available for scarab dung beetles, after the recent removal of wild...
Will human populations be limited by food?

Warren, S. G.

Historical examples of demographic change, in China, Italy, Nigeria, Utah, the Philippines, and elsewhere, together with simple mathematics and biological principles, show that stabilizing world population before it is limited by food supply will be more difficult than is generally appreciated. United Nations population projections are based on a logical fallacy in that they assume, in spite of the absence of necessary negative feedbacks, that all nations will converge rapidly to replacement-level fertility and thereafter remain at that level. The benign projections that have resulted from this assumption may have hindered efforts to make availability of birth-control a priority in development-aid. Education of women and provision of contraceptives have caused dramatic reductions in fertility, but many groups, including some that are well-educated, maintain high fertility. Small groups with persistent high fertility can grow to supplant low-fertility groups, resulting in continued growth of the total population. The global average fertility rate could rise even if each country's fertility rate is falling. In some low-fertility European countries where deaths exceed births, the population continues to grow because of immigration. Producing more than two offspring is normal for all animal species with stable populations, because their populations are limited by resources or predation rather than birth control. It may therefore be appropriate to view the growth of human population as the result not of excess fertility but rather of excess food. Even if the fertility rate is maintained far in excess of 2, the population cannot grow if food is limiting. Without the agricultural advances of the 20thcentury, world population could not have grown as it did from 1.7 billion in 1900 to 6 billion in 2000. The food supply may be enhanced in the future by genetic engineering and other innovations, but it may be limited by water shortage, climate change, pollution, and energy
Optimal Intermittent Operation of Water Distribution Networks under Water Shortage

Full Text Available Under water shortage conditions, it is necessary to exercise water consumption management practices in water distribution networks (WDN. Intermittent supply of water is one such practice that makes it possible to supply consumption nodal demands with the required pressure via water cutoff to some consumers during certain hours of the day. One of the most important issues that must be observed in this management practice is the equitable and uniform water distribution among the consumers. In the present study, uniformity in water distribution and minimum supply of water to all consumers are defined as justice and equity, respectively. Also, an optimization model has been developed to find an optimal intermittent supply schedule that ensures maximum number of demand nodes are supplied with water while the constraints on the operation of water distribution networks are also observed. To show the efficiency of the proposed model, it has been used in the Two-Loop distribution network under several different scenarios of water shortage. The optimization model has been solved using the honey bee mating optimization algorithm (HBMO linked to the hydraulic simulator EPANET. The results obtained confirm the efficiency of the proposed model in achieving an optimal intermittent supply schedule. Moreover, the model is found capable of distributing the available water in an equitable and just manner among all the consumers even under severe water shoratges.

The current and projected nurse workforce shortage has created significant pressure on health care organizations to examine their approach to managing talent. This includes the need for strategic development of new formal leaders. This article reports on a succession planning program for prospective nursing unit managers. Eight prospective management candidates participated in a Future Nursing Unit Managers program. The effectiveness of the program was measured through a comparison of pre- and postprogram surveys relating to participants' perception of personal managerial and leadership skills. Significant differences in scores from baseline to 6-month follow-up surveys were observed in the participants' confidence in undertaking the nursing unit manager role and in their management skills. Investment in structured programs to prepare nurses for leadership roles is strongly recommended as a management workforce strategy.

French authorities are considering the implementation of a simplified nutrition labelling system on food products to help consumers make healthier food choices. One of the most documented candidates (Five-Colour Nutrition Label/Nutri-score) is based on the British Food Standards Agency Nutrient Profiling System (FSA-NPS), a score calculated for each food/beverage using the 100 g amount of energy, sugar, saturated fatty acid, sodium, fibres, proteins, and fruits and vegetables. To assess its potential public health relevance, studies were conducted on the association between the nutritional quality of the diet, measured at the individual level by an energy-weighted mean of all FSA-NPS scores of foods usually consumed (FSA-NPS dietary index (FSA-NPS DI)), and the risk of chronic diseases. The present study aimed at investigating the relationship between the FSA-NPS DI and breast cancer risk. Prospective study. Population based, NutriNet-Santé cohort, France. 46 864 women aged ≥35 years who completed ≥3 24-hour dietary records during their first 2 year of follow-up. Associations between FSA-NPS DI and breast cancer risk (555 incident breast cancers diagnosed between 2009 and 2015) were characterised by multivariable-adjusted Cox proportional hazard models. A higher FSA-NPS DI (lower nutritional quality of the diet) was associated with an increased breast cancer risk (HR 1-point increment =1.06 (1.02-1.11), p=0.005; HR Q5vs.Q1 =1.52 (1.11-2.08), p trend=0.002). Similar trends were observed in premenopausal and postmenopausal women (HR 1-point increment =1.09 (1.01-1.18) and 1.05 (1.00-1.11), respectively).This study was based on an observational cohort using self-reported dietary data, thus residual confounding cannot be entirely ruled out. Finally, this holistic approach does not allow investigating which factors in the diet most specifically influence breast cancer risk. These results suggested that unhealthy food choices, as characterised by the FSA-NPS, may

This article describes one university's experience in creating a master's geriatric clinical nurse specialist-nurse educator program to address the nursing faculty shortage and the need for geriatric clinical nurse specialists. The successes and challenges are outlined, and curricular ideas that may be beneficial to other nursing programs also are presented. This program has enhanced the university's pool of clinical instructors, increased its ability to provide services to older adults, and allowed faculty to instruct and focus undergraduates in the distinctions of geriatric nursing care. The biggest challenges faced were marketing and recruitment of nurses; these challenges were addressed, and possible solutions are offered. The most immediate benefit of this program was the generation of geriatric clinical nurse specialists.

The present study examined the role of protection motivation variables in predicting rainwater tank adoption among urban householders. A regression analysis found that subjective knowledge, threat appraisal, response efficacy, response costs, subjective norms and social norms significantly predicted adaptive behavioural intentions (F(6, 399) = 50.769, p accounted for 43% of the variance in intentions to install a rainwater tank as a protective measure against future water shortages. Results further indicated that several variables uniquely contributed to the prediction of rainwater tank adoption (listed in order of relative contribution: response efficacy, threat appraisal, response costs, subjective knowledge and subjective norms). This suggests that people who perceive there is a real water shortage threat, and believe that rainwater tanks are effective in relieving the threat and require minimal or manageable effort to obtain, are more likely to install a tank on their property as a protective measure. Implications of these results are discussed from a research and policy perspective. Recommendations for future motivational research in the area of urban decentralised system acceptance and adoption are presented.
The nursing shortage: part way down the slippery slope.

Science.gov (United States)

Cowin, Leanne; Jacobsson, Denise

2003-07-01

The shortage of nurses has reached a crisis point for health care services. A number of issues including the effects of economic rationalism, generational differences, working conditions and nurse education are revisited in a discussion that aims to refuel the debate on workplace reform for nurses. Economic rationalism has altered the healthcare service landscape. Attempts to balance service delivery with workforce resources have led to possibly unforeseen changes. Highly skilled nurses are required in acute services, however resource allocation may prevent this. The nursing workforce is aging although the current nursing workforce consists of three generations: baby boomers, generation X and generation Y. There are significant ideological and work organisational differences between these generations leading to possible conflict between nurses. The pool of available nurses to fill employment vacancies is finite. Attracting overseas nurses to fill nurse vacancies will leave vacancies elsewhere and is not a long-term solution to the nursing shortage. Moreover, if the workplace has not addressed the reasons why nurses have left the health care workplace then there is a real danger of losing those recently attracted back into the workplace. Working conditions are a critical element within the retention puzzle. Job satisfaction dimensions such as autonomy and professional relationships are key components for improving working conditions. The final issue explored is the question of whether the tertiary education system is the most appropriate place in which to develop and educate nurses. It is suggested that workplace reforms should be the target of retention strategies rather than changes in the educational process of nursing.
Food insecurity and children's mental health: a prospective birth cohort study.

Maria Melchior

Full Text Available Food insecurity (which can be defined as inadequate access to sufficient, safe, and nutritious food that meets individuals' dietary needs is concurrently associated with children's psychological difficulties. However, the predictive role of food insecurity with regard to specific types of children's mental health symptoms has not previously been studied. We used data from the Longitudinal Study of Child Development in Québec, LSCDQ, a representative birth cohort study of children born in the Québec region, in Canada, in 1997-1998 (n = 2120. Family food insecurity was ascertained when children were 1½ and 4½ years old. Children's mental health symptoms were assessed longitudinally using validated measures of behaviour at ages 4½, 5, 6 and 8 years. Symptom trajectory groups were estimated to identify children with persistently high levels of depression/anxiety (21.0%, aggression (26.2%, and hyperactivity/inattention (6.0%. The prevalence of food insecurity in the study was 5.9%. In sex-adjusted analyses, children from food-insecure families were disproportionately likely to experience persistent symptoms of depression/anxiety (OR: 1.79, 95% CI 1.15-2.79 and hyperactivity/inattention (OR: 3.06, 95% CI 1.68-5.55. After controlling for immigrant status, family structure, maternal age at child's birth, family income, maternal and paternal education, prenatal tobacco exposure, maternal and paternal depression and negative parenting, only persistent hyperactivity/inattention remained associated with food insecurity (fully adjusted OR: 2.65, 95% CI 1.16-6.06. Family food insecurity predicts high levels of children's mental health symptoms, particularly hyperactivity/inattention. Addressing food insecurity and associated problems in families could help reduce the burden of mental health problems in children and reduce social inequalities in development.

Full Text Available A continuous production control inventory model for deteriorating items with shortages is developed. A number of structural properties of the inventory system are studied analytically. The formulae for the optimal average system cost, stock level, backlog level and production cycle time are derived when the deterioration rate is very small. Numerical examples are taken to illustrate the procedure of finding the optimal total inventory cost, stock level, backlog level and production cycle time. Sensitivity analysis is carried out to demonstrate the effects of changing parameter values on the optimal solution of the system.

Food irradiation is the process of exposing food to radiant or corpuscular energy: microwaves, ultraviolet light, gamma- and beta-rays. The treatment of foodstuffs with ionizing radiations is utilized to extend their shelf-life, to inhibit vegetable germination and sprouting, to delay the ripening of tropical fruits, to eliminate pest insects, to reduce or eliminate micro-organisms, spore-forming bacteria, parasites. The enzymes are more resistant and they are not inactivated by treating products with usual irradiation doses. This article summarizes the EU and Italian legislation about the matter and the list of authorized irradiation plants and irradiated foods. In addition, this work gives some information about the state-of-the art of the official controls in EU. It's interesting to note that about the 30% of integrators in some European state are irradiated but not adequately labelled. The European Committee for Standardization has selected the most important analytical methods to verify which foods result to be treated with ionizing radiations [it

Food for honeybees? Pollinators and seed set of Anthyllis barba-jovis L. (Fabaceae in arid coastal areas of the Mediterranean basin

Directory of Open Access Journals (Sweden)

Giovanni Benelli

2017-07-01

Full Text Available Abundance and diversity of insect pollinators are declining in many ecosystems worldwide. The abundance and diversity of wild and managed bees are related to the availability of continuous floral resources. In particular, in Mediterranean basin countries, the presence of wildflower spots enhances the establishment of social Apoidea, since coastal regions are usually characterized by pollen and nectar shortage in early spring and late summer. Anthyllis barba-jovis produces both nectar and pollen as important food source for bees helping them to overcome early spring period food shortage. We investigated flowering, seed set, and pollinator diversity of A. barba-jovis in arid coastal environments of the Mediterranean basin. Pollinator abundance reached a maximum in early April. Honeybees were the most common pollinators followed by bumblebees and solitary bees. Plants prevented from entomophilous pollination showed inbreeding depression with a strong decrease in seed-set. To the best of our knowledge, this is the first report on pollination ecology of A. barba-jovis.

IgE- mediated food allergy affects 6-8% of children. Our study aimed to define the correlations between the results obtained with skin prick tests (SPTs) using commercial extracts and fresh foods, and the correlations between these result and those obtained with specific IgE (sIgE) and/ or challenge. Children aged from 2 months to 6 years were recruited prospectively. Overall 571 children were positive to one food. In all children we performed SPT using commercial extracts of suspected food and fresh foods and sIgE. If SPT and sIgE test results did not correspond to the history, we performed open oral food challenge. Sensitivity of SPT with commercial extracts for all tested food was poor (3-35%), while sensitivity of fresh food skin prick tests (FFSPT) was excellent (50-100%), and showed correlation with open oral food challenge (pfood extracts are more effective in detecting sensitization and with levels of sIgE greater than class 3 could predict clinical reactivity, without the need for potentially hazardous food challenges.

Several solutions, ranging from increased technician duties to salary raises, automation, and increasing job satisfaction, have been presented in the literature as methods of assuaging the pharmacist shortage. Although a significant portion of pharmacy graduates from American pharmacy colleges are foreign nationals, no marketing strategies have been elucidated in the retention and recruitment of foreign nationals through labor certification. Labor certifications are generally approved by the Secretary of Labor if the following factors have been verified: 1) there are not sufficient United States workers who are able, willing, qualified, and available for employment; and 2) the employment of the foreign national will not adversely affect the wages and working conditions of U.S. workers similarly employed. When properly understood, the labor certification process is a test of the job market where foreigners, by virtue of their skills and qualifications, attain certification which subsequently leads to permanent residency (green card). The objective of this report is to elucidate the tedious yet effective method of retaining American-educated foreign nationals through labor certification.
Does despotic behavior or food search explain the occurrence of problem brown bears in Europe?

Bears foraging near human developments are often presumed to be responding to food shortage, but this explanation ignores social factors, in particular despotism in bears. We analyzed the age distribution and body condition index (BCI) of shot brown bears in relation to densities of bears and people, and whether the shot bears were killed by managers (i.e., problem bears; n = 149), in self-defense (n = 51), or were hunter-killed nonproblem bears (n = 1,896) during 1990–2010. We compared patterns between areas with (Slovenia) and without supplemental feeding (Sweden) of bears relative to 2 hypotheses. The food-search/food-competition hypothesis predicts that problem bears should have a higher BCI (e.g., exploiting easily accessible and/or nutritious human-derived foods) or lower BCI (e.g., because of food shortage) than nonproblem bears, that BCI and human density should have a positive correlation, and problem bear occurrence and seasonal mean BCI of nonproblem bears should have a negative correlation (i.e., more problem bears during years of low food availability). Food competition among bears additionally predicts an inverse relationship between BCI and bear density. The safety-search/naivety hypothesis (i.e., avoiding other bears or lack of human experience) predicts no relationship between BCI and human density, provided no dietary differences due to spatiotemporal habitat use among bears, no relationship between problem bear occurrence and seasonal mean BCI of nonproblem bears, and does not necessarily predict a difference between BCI for problem/nonproblem bears. If food competition or predation avoidance explained bear occurrence near settlements, we predicted younger problem than nonproblem bears and a negative correlation between age and human density. However, if only food search explained bear occurrence near settlements, we predicted no relation between age and problem or nonproblem bear status, or between age and human density. We found
Novel natural food antimicrobials.

Naturally occurring antimicrobial compounds could be applied as food preservatives to protect food quality and extend the shelf life of foods and beverages. These compounds are naturally produced and isolated from various sources, including plants, animals and microorganisms, in which they constitute part of host defense systems. Many naturally occurring compounds, such as nisin, plant essential oils, and natamycin, have been widely studied and are reported to be effective in their potential role as antimicrobial agents against spoilage and pathogenic microorganisms. Although some of these natural antimicrobials are commercially available and applied in food processing, their efficacy, consumer acceptance and regulation are not well defined. This manuscript reviews natural antimicrobial compounds with reference to their applications in food when applied individually or in combination with other hurdles. It also reviews the mechanism of action of selected natural antimicrobials, factors affecting their antimicrobial activities, and future prospects for use of natural antimicrobials in the food industry.

As shortages of food and energy still continue to constitute the major threats to the well-being of the human race, all actions aiming at overcoming these problems must be assigned vital importance. Of the two complementary ways of solving the food problem (i.e., increasing the production of food and decreasing the spoilage of food) a novel method designed to contribute to the latter purpose has been discussed at this symposium hosted by The Netherlands and held under the aegis of the Food and Agriculture Organization of the United Nations, the International Atomic Energy Agency and the World Health Organization. Progress made since the last symposium of this kind (Bombay, India, 1972) was reviewed from the technological, economic and wholesomeness points of view by participants from 39 countries (60% of the latter were of the developing world). From the reports presented on the use of radiations to control physiological changes in plants, feasibility of radiation preservation of potatoes, onions, garlic, as well as of some tropical and subtropical fruits (mangoes, papayas, litchis and avocado) was confirmed. For potatoes, onions and mangoes, optimal conditions of treatment and storage were established on a larger scale, combined with sizeable consumer trials. Combinations of ionizing radiation with chemicals (salycilic acid, for potatoes), and physical agents (ultraviolet rays, for papayas) have been reported to be successful against the incidence of rot. A considerable number of papers dealt with the control of microbiological spoilage of foods.

Food and fitness: associations between crop yields and life-history traits in a longitudinally monitored pre-industrial human population.

Severe food shortage is associated with increased mortality and reduced reproductive success in contemporary and historical human populations. Studies of wild animal populations have shown that subtle variation in environmental conditions can influence patterns of mortality, fecundity and natural selection, but the fitness implications of such subtle variation on human populations are unclear. Here, we use longitudinal data on local grain production, births, marriages and mortality so as to assess the impact of crop yield variation on individual age-specific mortality and fecundity in two pre-industrial Finnish populations. Although crop yields and fitness traits showed profound year-to-year variation across the 70-year study period, associations between crop yields and mortality or fecundity were generally weak. However, post-reproductive individuals of both sexes, and individuals of lower socio-economic status experienced higher mortality when crop yields were low. This is the first longitudinal, individual-based study of the associations between environmental variation and fitness traits in pre-industrial humans, which emphasizes the importance of a portfolio of mechanisms for coping with low food availability in such populations. The results are consistent with evolutionary ecological predictions that natural selection for resilience to food shortage is likely to weaken with age and be most severe on those with the fewest resources.

Full Text Available Orientation: Construction human resource management. Research purpose: The study examines the skilled labour supply in the South African construction industry and determines whether there is a relationship between trade certification, quality of work output and scarce labour skills. Motivation for the study: The rationale for the investigation is based on the view of scholars that a skilled labour shortage is preponderant in the South African construction industry even though there is a high level of youth unemployment in South Africa and that the perceived skills shortage contributes to a decrease in productivity and product quality. Research design, approach and method: The paper reviews relevant literature and employs a mixed method research approach in collecting empirical data from contracting companies within the Western Cape Province of South Africa that are listed on the Construction Industry Development Board contractor register. Main findings: The study demonstrated that there is no shortage of manpower, but there is a shortage of qualified or skilled tradesmen, such as electricians, plumbers, welders, fitters and carpenters, whose professions are more technical and require formal training and certification. The level of supply of skilled tradesmen is attributed to the lack of high-quality basic education, the state of the economy, compulsory certification of tradesmen and an ageing workforce. It was also found that there is a significant relationship between skilled labour shortages and the requirement that labour be certified and that work output is unsatisfactory when there is no certification requirement. Practical/managerial implications: Based on these findings, the study concludes that skilled labour shortages and poor work output quality continue to be experienced in the South African construction industry when workers are unable to obtain formal certification for informal work experience acquired through years of practice on
Metaphorical expressions used in Swedish news media narratives to portray the shortage of nurses and their working conditions.

The aim of the study is to uncover and reveal how nurses as a profession and their working conditions are dramatized and portrayed in Swedish media narratives about the shortage of nurses. The media is an arena where stakeholders can air their views of the healthcare sector in general and the situation for nurses in particular. The focus in this study is the debate in Sweden on the shortage of nurses. Qualitative discursive study. A discourse analysis of media narratives about nurses and their working conditions published in several Swedish newspapers from 2009-2014. 1779 articles were included in the study. A selection (113 articles) of these articles was further analysed using a qualitative discursive psychological approach. Nurses are portrayed as being good, concerned about and critical of healthcare managers and politicians for not taking action. The accused actors justify their actions by partially accepting or displacing responsibility. The shortage of nurses is framed as a social problem - a threat to patients' safety. Seven different types of metaphorical expression frame the problem as inevitable, beyond control, abstract, an individual and collegial problem and nurses as replaceable. In addition, nurses and patients are dehumanized and no-one is held responsible. This study analyses the role of the media in emphasizing the seriousness or obscurity of the problem and possible solutions to it. Alternative narratives are needed to re-frame the nursing shortage and to find sustainable solutions. © 2015 John Wiley & Sons Ltd.

2014-01-01

Full Text Available This paper aims to review the major food security issues in Bangladesh, with a brief reference to its past trend in agricultural output, constraints, and challenges in the coming decades. Food security relates directly to nutrition and health of a population which consequently influences a nation's socio-economic status. Despite Bangladesh has changed its status from a country with chronic food shortages to a self-sufficient one, it still faces food-security challenges. Few non-agricultural factors are identified as equally responsible for aggravating the food insecurity scenario. Since its independence in 1971, the country has constantly been facing issues like high population growth, political unrest, natural disasters which are contributing to food insecurity. Though industrialization is the order of the modern economy, agriculture remains the lifeblood of food security, especially for predominantly agrarian economies like Bangladesh. And this truth must be emphasized and implemented accordingly so that the predicted food crisis in near future can be successfully avoided. This article aims to review the performance of different agricultural sectors and to identify major setbacks to achieving food security in Bangladesh. This study is based on previously published researches on various food security issues in the context of Bangladesh.

It is widely acknowledged that drought management should move from a crisis to a risk-based approach. A risk-based approach to managing water resources requires a sound drought risk analysis, quantifying the probability and impacts of water shortage due to droughts. Impacts of droughts are for example crop yield losses, hydropower production losses, and water shortage for municipal and industrial use. Many studies analyse the balance between supply and demand, but there is little experience in translating this into economic metrics that can be used in a decision-making process on investments to reduce drought risk. We will present a drought risk analysis method for the Netherlands, with a focus on the underlying economic method to quantify the welfare effects of water shortage for different water users. Both the risk-based approach as well as the economic valuation of water shortage for various water users was explored in a study for the Dutch Government. First, an historic analysis of the effects of droughts on revenues and prices in agriculture as well as on shipping and nature was carried out. Second, a drought risk analysis method was developed that combines drought hazard and drought impact analysis in a probabilistic way for various sectors. This consists of a stepwise approach, from water availability through water shortage to economic impact, for a range of drought events with a certain return period. Finally, a local case study was conducted to test the applicability of the drought risk analysis method. Through the study, experience was gained into integrating hydrological and economic analyses, which is a prerequisite for drought risk analysis. Results indicate that the risk analysis method is promising and applicable for various sectors. However, it was also found that quantification of economic impacts from droughts is time-consuming, because location- and sector-specific data is needed, which is not always readily available. Furthermore, for some
Overview of allied health personnel shortages.

Upon learning that 95% of all fatal traffic accidents occur within three miles of one's home, an acquaintance moved to another residence four miles away and is still alive today. The world might be a much better place if most obstacles could be overcome this handily. Unfortunately, the problem of allied health personnel shortages appears to be more intractable. Because the situation is complicated in nature, it is most unlikely that any single remedy will suffice. Public and private interests have joined forces in many states, but it is abundantly clear that conventional market forces are unlikely to prevail. These forces usually focus on supply and demand. While shortages may cause entry-level salaries to rise, they do not stimulate academic institutions to increase their output nor will they affect the availability of research funding and/or doctoral training programs. Current market forces compel health facilities to engage in bidding wars for scarce manpower. Although individual job seekers may benefit, this practice does not increase the number of training program graduates. The federal government has a decisive role to play in assuring an adequate number of personnel to meet this nation's health care needs. Assistance is necessary in the form of providing entry- and advanced-level traineeships to accelerate the flow of part-time students pursuing doctorates, and to fund model student recruitment/retention projects. This role should encompass attracting students (particularly from minority and underserved portions of the population) to academic programs. The Disadvantaged Minority Health Improvement Act, PL 101-527 that was enacted in November 1990, contains only minimal provisions for allied health. Eligibility for student scholarship assistance is restricted to a small handful of allied health professions. Moreover, allied health is not eligible for the loan repayment program aimed at individuals who agree to serve on the faculty of health professions

Elaidic acid is the main unnatural trans fatty acid isomer occurring during partial hydrogenation of vegetable oils used as ingredients for the formulation of processed foods. The main objective is to assess associations between processed food intakes and plasma phospholipid elaidic acid concentrations within the European Prospective Investigation into Cancer and Nutrition study. A cross-sectional study was used to determine fatty acid profiles in 3,003 subjects from 16 centers. Single 24-h dietary recalls (24-HDR) were collected using a standardized computerized interview program. Food intakes were computed according to their degree of processing (moderately/nonprocessed foods, processed staple foods, highly processed foods). Adjusted ecological and individual correlations were calculated between processed food intakes and plasma elaidic acid levels. At the population level, mean intakes of highly processed foods were strongly correlated with mean levels of plasma elaidic acid in men (P = 0.0016) and in women (P = 0.0012). At the individual level, these associations remained but at a much lower level in men (r = 0.08, P = 0.006) and in women (r = 0.09, P = 0.0001). The use of an averaged 24-HDR measure of highly processed food intakes is adequate for predicting mean levels of plasma elaidic acid among European populations.

The national nursing shortage translates into a gap in home nursing care available to children with complex, chronic medical conditions and their family caregivers receiving palliative care consultations. A total of 38 home health nursing surveys were completed by families receiving pediatric palliative care consultation services at a freestanding children's hospital in the Midwest. The gap in the average number of nursing hours allotted versus received was 40 h/wk per family, primarily during evening hours. Parents missed an average of 23 hours of employment per week to provide hands-on nursing care at home, ranking stress regarding personal employment due to nursing shortage at 6.2/10. Families invested an average of 10 h/mo searching for additional nursing coverage and often resorted to utilizing more than 6 different home nurse coverage personnel per month. Families reported multiple delays to hospital discharges (mean, 15 days per delay) due to inability to find home nursing coverage. Respiratory technology and lack of Medicaid coverage ( P home nursing access. This study examines how the pediatric home nursing shortage translates into a lived experience for families with children with complex medical conditions receiving palliative care.

Full Text Available Water shortage and drought, as the most important hydro-climatic hazards, cause significant damages in case of most continents including SE Europe. An experimental field established in Bačka region (Vojvodina Autonomous Province, North Serbia for the purpose of droughts/water shortage monitoring and remote sensing under ongoing IPA project 'Water shortage hazard and adaptive water management strategies in the Hungarian-Serbian cross-border region' (WAHASTRAT. The main objective of this project is to determine water shortage conflicts on a local and regional level, and to reveal the frequency, extent and severity of future hydro-climatic hazards. The locations of eight measurement stations selected on the principle of representativeness in term of terrain configuration and soil cover. An area in which measurement stations were placed, covers about 1000 km2 (12% of total area of Bačka and includes geomorphic units which reliable represent the relief of the whole Bačka region. Measurement stations were placed on 4 out of 5 most common soil types in the Bačka and Vojvodina: chernozem, alluvial soils, smonitza and saline and alkali soils. A measurement equipment system was constructed for the requirements of the WAHASTRAT project. The aim was to design a user-friendly and affordable IT solution, which would enable continuous remote monitoring of meteorological parameters and soil moisture. Independent solar-powered measurement stations are able to automatically measure air temperature, air humidity, wind speed, wind direction, precipitation and soil moisture.

Neurosurgical workforce decision-making is typically driven by the 1 neurosurgeon per 100,000 population ratio proposed in 1977 in the Study on Surgical Services for the United States report. The actual ratio has always been higher than suggested. We evaluated whether the 1:100,000 ratio from the Study on Surgical Services for the United States report is still valid, whether there are enough neurosurgeons in the United States to meet patient needs, and whether demand is driven by patient need. For our analysis, the distribution of practicing US neurosurgeons was merged with census data to yield density indices of neurosurgeons by state; a survey assessing practice characteristics was e-mailed to practicing neurosurgeons; and a compilation of job advertisements for US neurosurgeons was evaluated. Multivariant statistical analyses yielded inconclusive results regarding patient demand because existing data sets are not designed to establish patient demand and many neurosurgeons are subspecialized. The data indicated that the ratio of neurosurgeons to total US population is 1:65,580. In the survey responses, neurosurgeon-to-patient ratios varied dramatically by state and were inconsistently correlated with whether neurosurgeons indicated they were overworked or underworked. The 305 job advertisements may indicate a shortage. Twenty-four percent of advertising practices indicated that they are recruiting only for emergency department coverage, and an additional 26% indicated that they might not be recruiting if not for the need for emergency coverage. Demand ratios should be reevaluated by region and subspecialty to consider changes in neurosurgery practice. A "shortage" in the employment market may reflect factors other than patient need.

This report gives a survey of results from the ''Norges forskningsraad'' ( The Norwegian Research Council) program EFFEKT (1996-2000) and some other relevant projects. The report focuses on areas relevant to the efficiency shortage problems and is made as a part of the foundation for the start of the competence project ''Competence Building - Capacity Shortage''. The challenge is to find adequate solutions that satisfies the demands from market participants, systems operators and market actors. This mainly contains problems of both operational and long term strategic character which primarily touches the following main areas: Peak load coverage, operating security and reserves, network capacity and environmental aspects. The results are reported under these headings from several relevant projects. The major challenges in the future will be: 1) Development of mechanisms that bring the right incentives for improved use of the flexibility in the end consumption. 2) Adaptation of the market and organisational conditions in order to improve the consumer flexibility. 3) Further development of the incentive structures for the network owners and systems operators so that the existing transferring capacity is used as well as possible and the macro economic development of the network is encouraged. 4) Profit estimations and financing of larger co-originated connections particularly across the country borders, in deregulated power markets. Particularly the first two challenges are probably a condition for the deregulated power markets as the Nordic one, shall be able to survive in the long run.

Productivity of Bedouin goats: Coping with shortages of water and adequate food

Choshniak, I.; Brosh, A.; Shkolnik, A.

1988-01-01

The study was carried out under outdoor summer conditions on goats that were watered only once every four days and goats that were watered once daily. Under each of the watering regimes the goats were fed on alfalfa hay (a high quality roughage), and Rhodes grass and wheat straw, medium and low quality feed respectively. In all trials except one, the goats maintained constant body weights. When goats were watered infrequently they gulped down volumes of water that often caused the osmolarity of the rumen fluid to drop from 360 mosm/kg to about 80 mosm/kg. Over this entire range of osmotic concentration the bacterial populations in the goats' rumen maintained their viability. By reducing the fluid flow through the gut, infrequent drinking helped to extend the time the digesta were retained along the digestive tract. As a result, digestibility of the roughage, particularly that of the low quality feed, was improved. Infrequent drinking was found to reduce the animals' demand for metabolizable energy and, as a result, enabled the goat to balance its energy metabolism on a low energy intake. It also improved the balance in the utilization of dietary protein while not interfering with the ability to recycle urea. It is concluded that the effects of the two deficiencies dealt with in this study are by no means additive. Frequent watering of ruminants in the desert is likely to increase their demand for food, lower their gain in digestible energy, increase their demand for metabolizable energy and make it more difficult for them to balance their energy budget. Improving feed quality for animals grazing in the desert, when water availability declines, is also not advantageous. It may only increase the animals' needs for water, render them dependent on frequent drinking and restrict their grazing area to the close vicinity of water sources. 30 refs, 10 figs, 6 tabs
The relationship between event-based prospective memory and ongoing task performance in chimpanzees (Pan troglodytes.

Directory of Open Access Journals (Sweden)

Theodore A Evans

Full Text Available Prospective memory is remembering to do something at a future time. A growing body of research supports that prospective memory may exist in nonhuman animals, but the methods used to test nonhuman prospective memory differ from those used with humans. The current work tests prospective memory in chimpanzees using a method that closely approximates a typical human paradigm. In these experiments, the prospective memory cue was embedded within an ongoing task. Tokens representing food items could be used in one of two ways: in a matching task with pictures of items (the ongoing task or to request a food item hidden in a different location at the beginning of the trial. Chimpanzees had to disengage from the ongoing task in order to use the appropriate token to obtain a higher preference food item. In Experiment 1, chimpanzees effectively matched tokens to pictures, when appropriate, and disengaged from the ongoing task when the token matched the hidden item. In Experiment 2, performance did not differ when the target item was either hidden or visible. This suggested no effect of cognitive load on either the prospective memory task or the ongoing task, but performance was near ceiling, which may have contributed to this outcome. In Experiment 3, we created a more challenging version of the task. More errors on the matching task occurred before the prospective memory had been carried out, and this difference seemed to be limited to the hidden condition. This finding parallels results from human studies and suggests that working memory load and prospective memory may have a similar relationship in nonhuman primates.

Irradiation Food has been approved in 52 countries worldwide. In Korea, 26 food items have been approved since 1987. Recently, the irradiation technology with high dose was applied for the development of Korean space foods. Besides the sanitary purpose, the irradiation technology was used for elimination of undesired products such as food allergens, nitrite, biogenic amines, and so on. In this paper, the status of irradiation in the field of food and other biotechnology in Korea will be presented. Food irradiation is known to be the best method for controlling pathogenic microorganisms and one of the best alternatives to the chemical fumigants or preservatives usually used for a sanitation treatment for international trade. Also, there are larger industrial groups dedicated to radiation processing other than food irradiation industry. In this paper, the status of irradiation food science and biotechnology in Korea will be presented

Radiation processing is a highly versatile preservation technique for the food industry. It is a cold treatment which can inhibit sprouting, eliminate insects and food pathogens, extend shelf life, decontaminate raw materials, and pasteurise or sterilise food and packaging materials. Recent developments, such as an International Standard for Irradiated Foods and a Code of Practice for the Operation of Radiation Facilities for the Treatment of Foods, are expected to stimulate and facilitate trade in radiation processed foods. These developments and prospects for commercialisation of this new technology in Australia are discussed

2014-12-01

To implement the vending machine food labeling provisions of the Patient Protection and Affordable Care Act of 2010 (ACA), the Food and Drug Administration (FDA or we) is establishing requirements for providing calorie declarations for food sold from certain vending machines. This final rule will ensure that calorie information is available for certain food sold from a vending machine that does not permit a prospective purchaser to examine the Nutrition Facts Panel before purchasing the article, or does not otherwise provide visible nutrition information at the point of purchase. The declaration of accurate and clear calorie information for food sold from vending machines will make calorie information available to consumers in a direct and accessible manner to enable consumers to make informed and healthful dietary choices. This final rule applies to certain food from vending machines operated by a person engaged in the business of owning or operating 20 or more vending machines. Vending machine operators not subject to the rules may elect to be subject to the Federal requirements by registering with FDA.
Reduce, reuse and recycle: a green solution to Canada's medical isotope shortage.

Galea, R; Ross, C; Wells, R G

2014-05-01

Due to the unforeseen maintenance issues at the National Research Universal (NRU) reactor at Chalk River and coincidental shutdowns of other international reactors, a global shortage of medical isotopes (in particular technetium-99m, Tc-99m) occurred in 2009. The operation of these research reactors is expensive, their age creates concerns about their continued maintenance and the process results in a large amount of long-lived nuclear waste, whose storage cost has been subsidized by governments. While the NRU has since revived its operations, it is scheduled to cease isotope production in 2016. The Canadian government created the Non-reactor based medical Isotope Supply Program (NISP) to promote research into alternative methods for producing medical isotopes. The NRC was a member of a collaboration looking into the use of electron linear accelerators (LINAC) to produce molybdenum-99 (Mo-99), the parent isotope of Tc-99m. This paper outlines NRC's involvement in every step of this process, from the production, chemical processing, recycling and preliminary animal studies to demonstrate the equivalence of LINAC Tc-99m with the existing supply. This process stems from reusing an old idea, reduces the nuclear waste to virtually zero and recycles material to create a green solution to Canada's medical isotope shortage. © 2013 Published by Elsevier Ltd.

Retirements of baby boomers will create a talent shortage in Finnish health care. Concurrently, difficulties exist in recruiting new personnel. This paper provides an overview concerning the bottlenecks in talent management in a Finnish hospital, and finds solutions for recruitment and retention problems of healthcare professionals (nurses and physicians). Because the healthcare staffing shortage is worldwide, the results of this paper are also useful internationally. The research was a qualitative case study and the research method used was group interview. Background data was gathered from the public media and healthcare trade organisations. The bottlenecks of talent management in hospital organisation seem to relate to retaining actions of senior personnel. Concurrently, the organisation should develop new practices for attracting new personnel. Very few efforts on image marketing and recruitment have been done. The Internet has not been fully exploited and recruitment information has not been sent even to the neighbouring nursing college. Job rotation has not been used as a help in recruitment and competence development. Difficulties exist in transmitting tacit knowledge from a retiring nurse to a junior nurse. Leadership skills of the superior seem to be important when retaining and committing senior personnel. Recruitment and retention problems encourage organisations to develop new recruitment and commitment practices as well as management and leadership skills.
The prospect of food irradiation and the contribution of radiation chemistry to enact the hygienic safety standard of irradiated foods

Wu Jilan; Yuan Rongyao

1986-01-01

Now, it is said that we are at the dawn of food irradiation application both nationally and internationally. However, referring to the acceptability of customers the labeling of irradiated foods has been a nightmare to the food processors. On the other hand the recommended international standard has the shortcomings of thinking in absolute terms. In this paper a proposal which puts special emphasis on enacting hygienic safety standard of individual irradiated food is recommended. The hygienic safety standard of the irradiated food may be classified in three classes: 1) its hygienic safety standard is similar to that of common food; 2) the maximum permissible quantities of harmful compounds induced by radiation must be controlled; and 3) the quantity of unique radiolysis products may by dutermined. Radiation chemistry plays an important role in enacting the hygienic safety standard of irradiated foods. For international cooperation in this field some suggestions are made
Water Scarcity and Future Challenges for Food Production

Directory of Open Access Journals (Sweden)

Noemi Mancosu

2015-03-01

Full Text Available Present water shortage is one of the primary world issues, and according to climate change projections, it will be more critical in the future. Since water availability and accessibility are the most significant constraining factors for crop production, addressing this issue is indispensable for areas affected by water scarcity. Current and future issues related to “water scarcity” are reviewed in this paper so as to highlight the necessity of a more sustainable approach to water resource management. As a consequence of increasing water scarcity and drought, resulting from climate change, considerable water use for irrigation is expected to occur in the context of tough competition between agribusiness and other sectors of the economy. In addition, the estimated increment of the global population growth rate points out the inevitable increase of food demand in the future, with an immediate impact on farming water use. Since a noteworthy relationship exists between the water possessions of a country and the capacity for food production, assessing the irrigation needs is indispensable for water resource planning in order to meet food needs and avoid excessive water consumption.

While a growing proportion of global food consumption is obtained through international trade, there is an ongoing debate on whether this increased reliance on trade benefits or hinders food security, and specifically, the ability of global food systems to absorb shocks due to local or regional losses of production. This paper introduces a model that simulates the short-term response to a food supply shock originating in a single country, which is partly absorbed through decreases in domestic reserves and consumption, and partly transmitted through the adjustment of trade flows. By applying the model to publicly-available data for the cereals commodity group over a 17 year period, we find that differential outcomes of supply shocks simulated through this time period are driven not only by the intensification of trade, but as importantly by changes in the distribution of reserves. Our analysis also identifies countries where trade dependency may accentuate the risk of food shortages from foreign production shocks; such risk could be reduced by increasing domestic reserves or importing food from a diversity of suppliers that possess their own reserves. This simulation-based model provides a framework to study the short-term, nonlinear and out-of-equilibrium response of trade networks to supply shocks, and could be applied to specific scenarios of environmental or economic perturbations.

Full Text Available This study proposes Caring Science as an innovative way to facilitate food systems sustainability in areas of the world that continue to suffer from food insecurity and food shortages. An interdisciplinary group that included a nurse, an agronomist, an environmentalist, and a statistical analyst collaborated to study food sustainability in a village in Bambui, Cameroon. The village was composed of only women and children, and all the women were diagnosed with HIV/AIDS. This interdisciplinary approach not only met the food needs of the village, but, within the assessment process, identified other needs as well. This interdisciplinary approach facilitated holistic assessment of food, finances, personal self-worth and health.

Energy, water and food are critical resources for sustaining social development and human lives; human beings cannot survive without any one of them. Energy crises, water shortages and food security are crucial worldwide problems. The nexus of energy, water and food has received more and more attention in the past decade. Energy, water and food are closely interrelated; water is required in energy development such as electricity generation; energy is indispensable for collecting, treating, and transporting water; both energy and water are crucial inputs for food production. Changes of either of them can lead to substantial impacts on other two resources, and vice versa. Effective decisions should be based on thorough research efforts for better understanding of their complex nexus. Rapid increase of population has significantly intensified the pressures on energy, water and food. Addressing and quantifying their interactive relationships are important for making robust and cost-effective strategies for managing the three resources simultaneously. In addition, greenhouse gases (GHGs) are emitted in energy, water, food production, consequently making contributions to growing climate change. Reflecting environmental impacts of GHGs is also desired (especially, on the quality and quantity of fresh water resources). Thus, a socio-economic model is developed in this study to quantitatively address the complex connections among energy, water and food production. A synthetic problem is proposed to demonstrate the model's applicability and feasibility. Preliminary results related to integrated decisions on energy supply management, water use planning, electricity generation planning, energy facility capacity expansion, food production, and associated GHG emission control are generated for providing cost-effective supports for decision makers.

While incentives to increase generic drug use have achieved significant savings, other cost-containment measures are required. Tendering is a formal procedure to purchase medications using competitive bidding for a particular contract. Although useful for cost containment, tendering can lead to decreased competition in a given market. Consequently, drug shortages can occur, resulting in changes to treatment plans to products that may have lower efficacy and/or an increased risk of adverse effects. Therefore, care must be taken to ensure that tendering does not negatively impact patient care or the health care system. A large and expanding portion of total pharmaceutical expenditure is for biologic therapies. These agents have revolutionized the treatment of many diseases, including cancer and inflammatory conditions; however, patient access to biologic drugs can be limited due to availability, insurance coverage, and cost. As branded biologic therapies reach the end of patent- and data-protection periods, biosimilars are being approved as lower-cost alternatives. Biosimilars are products that are highly similar to the originator product with no clinically meaningful differences in terms of safety, purity, or potency. As more biosimilars receive regulatory approval and adoption increases, these therapies are expected to have an

A diet rich in phyto-oestrogens has been suggested to protect against a variety of common diseases but UK intake data on phyto-oestrogens or their food sources are sparse. The present study estimates the average intakes of isoflavones, lignans, enterolignans and coumestrol from 7 d food diaries and provides data on total isoflavone, lignan and phyto-oestrogen consumption by food group. Development of a food composition database for twelve phyto-oestrogens and analysis of soya food and phyto-oestrogen consumption in a populationbased study. Men and women, aged 40–79 years, from the general population participating in the Norfolk arm of the European Prospective Investigation into Cancer and Nutrition (EPIC-Norfolk) between 1993 and 1997, with nutrient and food data from 7 d food diaries. A subset of 20 437 participants. The median daily phyto-oestrogen intake for all men was 1199 mg (interquartile range 934–1537mg; mean 1504mg, SD 1502mg) and 888mg for all women (interquartile range 710–1135 mg; mean 1205 mg, SD 1701mg). In soya consumers, median daily intakes were higher: 2861 mg in men (interquartile range 1304–7269mg; mean 5051mg, SD 5031mg) and 3142 mg in women (interquartile range 1089–7327mg; mean 5396 mg, SD 6092 mg). In both men and women, bread made the greatest contribution to phyto-oestrogen intake – 40?8% and 35?6%, respectively. In soya consumers, vegetable dishes and soya/goat’s/sheep’s milks were the main contributors – 45?7% and 21?3% in men and 38?4% and 33?7% in women, respectively. The ability to estimate phyto-oestrogen intake in Western populations more accurately will aid investigations into their suggested effects on health.

The commercialization of food irradiation in Japan was started in 1973 for the sprout inhibition of potatoes as the first successful food irradiation facility in the world. Since approval of potato irradiation, no items has been commercialized in Japan. However, international agreement for phase out of methyl bromide after 2005 and increasing incidences of foodborn diseases such as by Escherichia coli O157:H7 are forcing to have interesting to food irradiation. Takasaki Radiation Chemistry Research Establishment has long experiences on research of irradiation effect and engineering of food irradiation in Japan. From these back ground, working group of food irradiation was organized at August 1997 by some members of Department of Radiation Research for Environment and Resources and Advanced Technology Center for supporting technically on commercialization of food irradiation. This report presents the result of discussion in working group on generalization up to date researches of food irradiation, application fields and items, technical problems and future prospects of this technology in Japan.

Pakistan as well as neighbouring countries are faced with critical water shortage for the last few decades. The demand for water has outstripped its supply making the availability of safe water sources an issue Also conflicts over water sharing are expected in many regions of the world. Thus, because of this looming crisis water problems are getting increasing attention all over the world. With the advancement of desalination technology many countries had resorted removal of salts from brackish and sea water as an alternative water supply and they are now viewing desalination as a future solution to problems of lack of water. Today, over 100 countries use desalting requirement. A total of 12,451 desalting units (of a unit size of 100 m/sup 3//d or more) with a total capacity of 22,735,000 m /d had been installed or contracted worldwide. Brackish water desalination plants contribute with 9,400,000 m3/d, whereas the capacity of the sea water plants had reached up to 13,300,000 m3/d. This paper will discuss the use of desalination to produce potable water from saline water for domestic or municipal purposes and also the available desalination techniques that have been developed over the years and have achieved commercial success.

The debate over the status of the physician workforce seems to be concluded. It now is clear that a shortage of physicians exists and is likely to worsen. In retrospect it seems obvious that a static annual production of physicians, coupled with a population growth of 25 million persons each decade, would result in a progressively lower physician to population ratio. Moreover, Cooper has demonstrated convincingly that the robust economy of the past 50 years correlates with demand for physician services. The aging physician workforce is an additional problem: one third of physicians are over 55 years of age, and the population over the age of 65 years is expected to double by 2030. Signs of a physician and surgeon shortage are becoming apparent. The largest organization of physicians in the world (119,000 members), the American College of Physicians, published a white paper in 2006 titled, "The Impending Collapse of Primary Care Medicine and Its Implications for the State of the Nation's Health Care" [37]. The American College of Surgeons, the largest organization of surgeons, has published an article on access to emergency surgery [38], and the Institute of Medicine of the National Academies of Science has published a book on the future of emergency care (Fig. 10). The reports document diminished involvement and availability of emergency care by general surgeons, neurologic surgeons, orthopedists, hand surgeons, plastic surgeons, and others. The emergency room has become the primary care physician after 5 PM for much of the population. A survey done by the Commonwealth Fund revealed that less than half of primary care practices have an on-call arrangement for after-hours care. Other evidence of evolving shortage are reports of long wait times for appointments, the hospitalist movement, and others. The policies for the future should move beyond dispute over whether or not a shortage exists. The immediate need is for the United States, as a society, to commit to

2004-01-01

Aspects of the recent report by the Ontario Electricity Conservation and Supply Task Force and Independent Market Operator which forecasts acute power supply shortages in Ontario, are discussed. Immediate action is recommended to avert the problem. The principal recommendation concerns the adoption of Demand Side Management as a tool to reduce the widening gap between supply and demand, citing supply shortage, imports, high prices, deregulated market and environmental concerns as the driving forces which push for the adoption of DSM. It is claimed that DSM, through its tools such as Demand/Load Response Programs and Time-of-Use rates has the capacity to create the necessary balance between supply and demand more efficiently, and in a more timely fashion than supply side management. The demand for adoption of DSM is justified on the basis of a careful examination of the magnitude and significance of each of the driving forces affecting the electricity supply in Ontario, as well as the benefits and techniques of DSM designed to manage power shortages. Energy Conservation and Efficiency and Demand/Load Response Programs are discussed as the principal DSM techniques, while Dynamic/Real Time Pricing, Time-of-Use Rates, Automated /Smart Metering, Web-based/Communication Systems, Reliability-based Programs, Market/Price-based programs, and Types of Load Control are described as the principal tools used by DSM.

The shortages of nurses in NSW: a motivation hygiene approach to identifying problems and solutions.

Science.gov (United States)

Carroll, E; Dwyer, L

1988-01-01

For a number of years public hospitals in NSW have experienced high turnover figures for nursing staff and have been unable to recruit sufficient numbers of registered nurses back into hospital employment. This paper outlines factors on both the demand and the supply side which contribute to the present shortage. It then goes on to argue that a greater appreciation of the causes of the shortage, and strategies for its resolution, can be gained by presenting the issues from the perspective of Herzberg's Motivation--Hygiene Theory. 'Motivation' factors, providing satisfaction to nurses, include achievement and recognition, the work itself, responsibility, advancement and potential for personal growth. 'Hygiene' factors, producing dissatisfaction, include physical working conditions, employer policies and administrative practices, interpersonal relations, salary. Discussion of the issues from this perspective indicates that strategies to resolve the crisis must proceed on two fronts. Continuing efforts must be made to promote job satisfaction among nurses while at the same time reducing the incidence of factors promoting job dissatisfaction.

The shortage of doctors, especially in remote areas, is a critical issue for the development of national health systems and has thus been the focus of a number of international cooperation projects. An exploratory and qualitative study was conducted to examine cooperation between Brazil, Angola and Cuba. A nonsystematic literature review was conducted of selected open access articles and official documents addressing relevant health cooperation initiatives. Previously selected characteristics of actions designed to redress the shortage of doctors were compared. It was concluded that the interactions between the three countries were fruitful and potentially beneficial for the health of the population of these countries. South-South cooperation between these countries showed positive results in the educational and regulatory dimensions and adopted a non-dependence perspective that seeks to strengthen endogenous capacity, which are important factors for evaluating the structural components of health systems.

Richter, Beate; Bokelmann, Wolfgang

2016-02-01

In the food industry the subject of food losses is of great importance due to economic balance and an efficient application of resources as well as the development of an efficient food chain system. This paper presents the explorative results of a quantitative survey of leading companies of the German food industry to evaluate the relevance and handling of this issue. The investigation reveals that the topic food losses have a high significance in the food industry which will probably increase in future. A sample breakdown by branches indicates that the issue has the highest relevance for companies in the confectionery industry. These companies as well as those in the meat and fish industry want to consider the subject prospectively more powerful in their companies. Across the food industry, there is no communication to consumers of the efforts concerning food losses. And companies in the confectionery industry and in the fruit and vegetable industry rather want to engage more powerful in this topic if consumers' interest increases. But in order to minimize food losses at all stages along the supply chain, communication and collaboration at all stages is essential, especially the communication to consumers. Thus, it has to be verified whether a suitable communication can lead to advantages in competition and become an important issue for companies to differentiate from competitors.

Full Text Available Background: Rate allergenic properties of the complementary food line based on grains, fruits/vegetables and meat in the diet of infants (0–1 years old. Methods: The study included children aged 4–6 months with natural, mixed or artificial feeding, who had not received any complementary food before. The children were almost healthy or had a burdened allergic history. Complementary foods (porridge, vegetable puree, meat puree and fruit puree were administered basing on an individual plan depending on age, nutritional status and nature of feces. Tolerability of products and dynamics of mass-height and laboratory parameters were evaluated. At the beginning and at the end of the study, capillary blood was taken to determine the content of hemoglobin in red blood cells (MCH, the equivalent of hemoglobin in reticulocytes (RetHe, iron, ferritin, prealbumin, and specific E class immunoglobulin (IgE to the proteins in cow's and goat milk, apples, pears, prunes, zucchini, broccoli, cauliflower, rice, maize, buckwheat, turkey meat, and rabbit meat (quantitative allergy diagnostics using an express method. In addition, a scatological study was performed. Results: 60 healthy children received complementary foods based on grains, fruits/vegetables and meat on a step-by-step basis. The level of specific IgE to food allergens in all children under the study was within normal range (0–135 IU/ml both initially and after the administration of all the complementary foods studied. Conclusion: The investigated complementary foods have a low sensitizing potential, including in children with a burdened allergic history. This allows us to describe them as hypoallergenic products.

Davies, Kevin M; Deroles, Simon C

2014-04-01

Plant cell cultures can offer continuous production systems for high-value food and health ingredients, independent of geographical or environmental variations and constraints. Yet despite many improvements in culture technologies, cell line selection, and bioreactor design, there are few commercial successes. This is principally due to the culture yield and market price of food products not being sufficient to cover the plant cell culture production costs. A better understanding of the underpinning biological mechanisms that control the target metabolite biosynthetic pathways may allow the metabolic engineering of cell lines to provide for economically competitive product yields. However, uncertainty around the regulatory and public acceptance of products derived from engineered cell cultures presents a barrier to the uptake of the technology by food product companies.

The UN Food and Agriculture Organization has dubbed October 16 World Food Day in an effort to create awareness and generate interest in the efforts being made to alleviate hunger and malnutrition, and to increase food production. A flag-raising ceremony marked the 17th World Food Day, on investing in food security, in Accra, Ghana. The Vice-President of Ghana noted at the ceremony that his government has made agriculture its top priority and is determined to invest as much as needed to achieve significant growth in the sector. The government is also taking steps to make agriculture so attractive that both private individuals and companies will find it a profitable sector in which to partake. The government of Ghana will provide its fullest cooperation and support in all technical and logistical aspects of the production process to prospective investors in the sector. Enlightened government policies are needed to ensure a broader framework for improving food security through agricultural development.

Angotti, T

2015-04-01

Proponents of urban agriculture have identified its potential to improve health and the environment but in New York City and other densely developed and populated urban areas, it faces huge challenges because of the shortage of space, cost of land, and the lack of contemporary local food production. However, large portions of the city and metropolitan region do have open land and a history of agricultural production in the not-too-distant past. Local food movements and concerns about food security have sparked a growing interest in urban farming. Policies in other sectors to address diet-related illnesses, environmental quality and climate change may also provide opportunities to expand urban farming. Nevertheless, for any major advances in urban agriculture, significant changes in local and regional land use policies are needed. These do not appear to be forthcoming any time soon unless food movements amplify their voices in local and national food policy. Based on his experiences as founder of a small farm in Brooklyn, New York and his engagement with local food movements, the author analyzes obstacles and opportunities for expanding urban agriculture in New York.

The status and prospects for genetically modified food in Europe and Croatia

Directory of Open Access Journals (Sweden)

Nada KNEEVIC

2013-03-01

Full Text Available In the last sixteen years worldwide production of genetically modified (GM crops has been increased sharply. At the same time, consumer?s attitudes toward food products made from GM ingredients have been largely negative. This review considers the global production of GM plants in 2011 and consumer attitudes towards genetically modified foods in Europe and Croatia. While planted areas of GM crops grow worldwide, data from European surveys shows generally negative consumer?s perception towards GM food. Eurobarometer survey from 2010 was especially pointed out, where Croatian consumers were included in research for first time. It has been shown that the Croatian, even more than Europeans, do not approve the use of genetically modified food in human consumption. This aversion to GM crops is based on the personal attitude of consumers, whereas the two main risks cited are: potential health risk and preference for natural food, and social risks which include possible adverse effects of GM plants on the environment. Research has shown that the perceived level of risk by consumers can be mitigated if the confidence is built in state institutions and scientific research.

The U.S Congress initiated sanctions against Iran after the 1979 U.S. Embassy hostage crisis in Tehran, and since then the scope of multilateral sanctions imposed by the United States, the European Union, and the United Nations Security Council have progressively expanded throughout the intervening years. Though primarily targeted at Iran's nuclear proliferation activities, sanctions have nevertheless resulted in negative public health outcomes for ordinary Iranian citizens. This includes creating vital domestic shortages to life-saving medicines, leaving an estimated 6 million Iranian patients with limited treatment access for a host of diseases. Sanctions have also crippled Iran's domestic pharmaceutical industry, leading to the disruption of generic medicines production and forcing the country to import medicines and raw materials that are of lower or questionable quality. Countries such as the United States have responded to this medical crisis by implementing export control exemptions with the aim of easing the trade of humanitarian goods (including certain pharmaceuticals and medical devices). However, despite these efforts, pharmaceutical firms and international banking institutions remain cautious about doing business with Iran, leaving the country faced with continuing shortages. We conducted a review of key characteristics of the Iranian drug shortage that identified 73 shortage drugs that closely tracked with the disease burden in the country. Additionally, 44 % of these drugs were also classified as essential medicines by the World Health Organization. A vast majority of these drugs were also covered under export control exemptions that theoretically should make them easier to procure, but nevertheless will still in shortage. Based on our review of the sanctions regulatory framework and key characteristics of the Iranian drug shortage, we propose policy intervention leveraging the recently negotiated P5 + 1 agreement that begins the process of

Problems related to food security in Russian Arctic (dietary imbalance, predominance of carbohydrates, shortage of milk products, vegetables and fruits, deficit of vitamins and microelements, chemical, infectious and parasitic food contamination) have been defined in the literature. But no standard protocol of food security assessment has been used in the majority of studies. Our aim was to obtain food security indicators, identified within an Arctic collaboration, for selected regions of the Russian Arctic, Siberia and the Far East, and to compare food safety in these territories. In 18 regions of the Russian Arctic, Siberia and the Far East, the following indicators of food security were analyzed: food costs, food consumption, and chemical and biological food contamination for the period 2000-2011. Food costs in the regions are high, comprising 23-43% of household income. Only 4 out of 10 food groups (fish products, cereals, sugar, plant oil) are consumed in sufficient amounts. The consumption of milk products, eggs, vegetables, potatoes, fruits (and berries) is severely low in a majority of the selected regions. There are high levels of biological contamination of food in many regions. The biological and chemical contamination situation is alarming, especially in Chukotka. Only 7 food pollutants are under regular control; among pesticides, only DDT. Evenki AO and Magadan Oblast have reached peak values in food contaminants compared with other regions. Mercury in local fish has not been analyzed in the majority of the regions. In 3 regions, no monitoring of DDT occurs. Aflatoxins have not been analyzed in 5 regions. Nitrates had the highest percentage in excess of the hygienic threshold in all regions. Excesses of other pollutants in different regions were episodic and as a rule not high. Improvement of the food supply and food accessibility in the regions of the Russian Arctic, Siberia and the Far East is of utmost importance. Both quantitative and qualitative

Results Modelling of healthy eating predicted lower child food fussiness and higher interest in food one year later, and pressure to eat predicted lower child interest in food. Restriction did not predict changes in child eating behaviour. Maternal feeding practices did not prospectively predict child food responsiveness or child BMI. Conclusion Maternal feeding practices appear to influence young children's eating behaviour but not weight status in the short term.

Providing foods to space crew is the important requirements to support long term manned space exploration. Foods fill not only physiological requirements to sustain life, but psychological needs for refreshment and joy during the long and hard mission to extraterrestrial planets. We designed joyful and healthy recipe with materials (plants, insects, fish et.cet. la.), which can be produced by the bio-regenerative agricultural system operated at limited resources available in spaceship or on Moon and Mars. And we need to get the storage method of the food without the problem of food poisoning. The consideration about the food allergy is necessary, too. Nutritional analysis on the basic vegetable menu consisting of rice, barley, soybean, sweet potato cassava, quinoa and green reveals a shortage of vitamins D and B12, cholesterol and sodium salt. Since vitamin D deficiency results in demineralization of bone. Vitamin B12 is essential to prevent pernicious anemia. Fish contains both vitamins D and B12. The pupa of the silkworm becomes the important nourishment source as protein and lipid. The silk thread uses it as clothing and cosmetics and medical supplies. However, we can use the silk thread as food as protein. A law of nature shakes high quality oils and fats included in termite for cooking. I use the bee as food after having used it for the pollination of the plant. Of course the honey becomes the important food, too. The snail and mud snail become the food as protein. We decided to use the menu consisting of the basic vegetarian menu plus insect and loach for further conceptual design of space agriculture. We succeeded to develop joyful and nutritious space recipe at the end. Since energy consumption for physical exercise activities under micro-or sub-gravity is less than the terrestrial case, choice of our space foods is essential to suppress blood sugar level, and prevent the metabolic syndrome. Because of less need of agricultural resources at choosing

2009-05-01

Full Text Available Abstract Background Primary care physicians have been shown to play an important role in the general health of the communities in which they serve. In spite of their importance, however, there has been a decrease in the number of physicians interested in pursuing primary care fields, while the proportion of specialists continues to increase. The prediction of an overall physician shortage only augments this issue in the US, where this uneven distribution is particularly evident. As such, serious effort to increase the number of practicing primary care physicians is both necessary and beneficial for meeting this country's health care needs. Discussion There are several factors at play which contribute to the decrease in the number of practicing physicians in primary specialties. Lifestyle concerns, such as schedule and income, as well as the lack of prestige associated with this field seem to be among the most prevalent reasons cited for the diminishing interest. Multifaceted concerns such as these, however, are difficult to adequately invalidate; doing so would not only require a great deal research, but also a good deal of time – a resource which is in short supply given the current physician shortage being faced. Thus, a more immediate solution may lie in the increased recruitment and continued support of those individuals who are already associated with primary care service. This is particularly relevant given the Association of American Medical College's goal of increasing medical school enrollment by 15% over the next 10 years. Several groups have been shown to be large contributors to primary care in the US. Here, we focus on three such groups: minority students, International Medical Graduates (IMGs and Osteopathic Physicians (DOs. Although these groups are highly diverse individually, they all share the distinction of being underutilized in regard to the current primary care shortages faced. Thus, through more fully accentuating these

Aptamers are short and functional single-stranded oligonucleotide sequences selected from systematic evolution of ligands by exponential enrichment (SELEX) process, which have the capacity to recognize various classes of target molecules with high affinity and specificity. Various analytical aptamers acquired by SELEX are widely used in many research fields, such as medicine, biology, and chemistry. However, the application of this innovative and emerging technology to food safety is just in infant stage. Food safety plays a very important role in our daily lives because varieties of poisonous and harmful substances in food affect human health. Aptamer technique is promising, which can overcome many disadvantages of existing detection methods in food safety, such as long detection time, low sensitivity, difficult, and expensive antibody preparation. This review provides an overview of various aptamer screening technologies and summarizes the recent applications of aptamers in food safety, and future prospects are also discussed.

The viewpoints of "medicine food homology" (MFH) conform to today's food requirements of returning to a natural and green healthy life. This paper aims to introduce the concept of MFH and its origin and evolution, and analyze the relationship between food and Chinese medicine. In this review, more than 80 MFH materials approved by China's Ministry of Health are listed and their effective ingredients are summarized in detail. Their treatment mechanism in TCM and western medicine are summarized too. Moreover, some new MFH resources that have been gradually developed are also introduced. MFH materials are a treasure house of functional factors for current functional foods. Innovative ideas for the development of MFH resources in current functional foods are prospected and discussed, such as taking advantage of Chinese diet theory, building a database for MFH varieties and developing new methods and technologies. At present, modern research for the development of MFH functional foods is still in its primary stage, there is still much work required in the popularization of the MFH concept and the development of new products. Knowledge and technological innovations in this area should be accelerated in the future to promote the modernization of MFH.

Hundreds of drug products are currently marketed in the United States without approval from the FDA. The 2006 Unapproved Drugs Initiative (UDI) requires manufacturers to remove these drug products from the market or obtain FDA approval by demonstrating evidence of safety and efficacy. Once the FDA acts against an unapproved drug, fewer manufacturers remain in the market, potentially enabling drug price increases and greater susceptibility to drug shortages. There is a need for systematic study of the UDI's effect on prices and shortages of all targeted drugs. To examine the clinical evidence for approval and association with prices and shortages of previously unapproved prescription drugs after being addressed by the UDI. Previously unapproved prescription drugs that faced UDI regulatory action or with at least 1 product that received FDA approval through manufacturers' voluntary compliance with the UDI between 2006 and 2015 were identified. The clinical evidence was categorized as either newly conducted clinical trials or use of previously published literature and/or bioequivalence studies to demonstrate safety and efficacy. We determined the change in average wholesale price, presence of shortage, and duration of shortage for each drug during the 2 years before and after UDI regulatory action or approval through voluntary compliance. Between 2006 and 2015, 34 previously unapproved prescription drugs were addressed by the UDI. Nearly 90% of those with a drug product that received FDA approval were supported by literature reviews or bioequivalence studies, not new clinical trial evidence. Among the 26 drugs with available pricing data, average wholesale price during the 2 years before and after voluntary approval or UDI action increased by a median of 37% (interquartile range [IQR] = 23%-204%; P Innovation; from the Blue Cross Blue Shield Association to better understand medical technology evidence generation; from the Centers for Medicare & Medicaid Services to

This study proposed a holistic three-fold scheme that synergistically optimizes the benefits of the Water-Food-Energy (WFE) Nexus by integrating the short/long-term joint operation of a multi-objective reservoir with irrigation ponds in response to urbanization. The three-fold scheme was implemented step by step: (1) optimizing short-term (daily scale) reservoir operation for maximizing hydropower output and final reservoir storage during typhoon seasons; (2) simulating long-term (ten-day scale) water shortage rates in consideration of the availability of irrigation ponds for both agricultural and public sectors during non-typhoon seasons; and (3) promoting the synergistic benefits of the WFE Nexus in a year-round perspective by integrating the short-term optimization and long-term simulation of reservoir operations. The pivotal Shihmen Reservoir and 745 irrigation ponds located in Taoyuan City of Taiwan together with the surrounding urban areas formed the study case. The results indicated that the optimal short-term reservoir operation obtained from the non-dominated sorting genetic algorithm II (NSGA-II) could largely increase hydropower output but just slightly affected water supply. The simulation results of the reservoir coupled with irrigation ponds indicated that such joint operation could significantly reduce agricultural and public water shortage rates by 22.2% and 23.7% in average, respectively, as compared to those of reservoir operation excluding irrigation ponds. The results of year-round short/long-term joint operation showed that water shortage rates could be reduced by 10% at most, the food production rate could be increased by up to 47%, and the hydropower benefit could increase up to 9.33 million USD per year, respectively, in a wet year. Consequently, the proposed methodology could be a viable approach to promoting the synergistic benefits of the WFE Nexus, and the results provided unique insights for stakeholders and policymakers to pursue

Zoonoses are diseases that are transmitted naturally between animals and humans. The control of food-borne zoonoses within the European Union is a prerequisite for assuring a functional internal market and consequently represents an important item on the political agenda. Unfortunately, until recently, gaining a clear view of the current incidence of food-borne zoonoses and the prevalence of its causative agents has been frustrated by the absence of reliable monitoring and reporting systems. Similarly, it has become clear that, Europe wide, one has witnessed only limited success with regard to the control of important food-borne agents such as Salmonella spp. The European Union has adopted legislation to remedy this situation and to control food-borne zoonoses in primary production. This contribution discusses the incentives for introducing EU Directive 2003/99/EC and EU Regulation No. 2160/2003, summarises their essentials and discusses major ramifications of both pieces of legislation for the prevention of food-borne zoonoses. It is concluded that there is reason for cautious optimism concerning human salmonellosis, while for other food-borne zoonoses there should be a call for action.

Full Text Available Most patients with chronic idiopathic urticaria (CIU need long-term treatment but there is little known about the prognosis of CIU. The aim of this study was to evaluate the natural course of CIU and to find out if there are risk factors that predict the prognosis. In this prospective study, we obtained data from patients first diagnosed and treated for CIU between September 2003 and September 2005. This study was included 157 patients with CIU. We observed duration of the disease, effects of food additives and preservatives in CIU. As possible prognostic factors we observed sex, age, atopy, intolerance to food additives and preservatives. Allergic reactions were seen to appear in 37% (n=50 cases due to natural foods, in 36% (n=49 cases due to foods containing additives, and in 27% (n=37 cases due to both natural foods and foods containing additives. For patients with CIU, food colors, sweeteners and preservatives that are added into foods are an important etiological factor. Moreover, histamine and histamine-like endogen pharmacological agents can cause allergic reactions. Hence, these foods should be taken into consideration in etiology especially in patients with CIU, and due to potential etiology, elimination of patients from these foods for a while is a significant step in treatment.

Full Text Available Background. Problems related to food security in Russian Arctic (dietary imbalance, predominance of carbohydrates, shortage of milk products, vegetables and fruits, deficit of vitamins and microelements, chemical, infectious and parasitic food contamination have been defined in the literature. But no standard protocol of food security assessment has been used in the majority of studies. Objectives. Our aim was to obtain food security indicators, identified within an Arctic collaboration, for selected regions of the Russian Arctic, Siberia and the Far East, and to compare food safety in these territories. Study design and methods. In 18 regions of the Russian Arctic, Siberia and the Far East, the following indicators of food security were analyzed: food costs, food consumption, and chemical and biological food contamination for the period 2000–2011. Results. Food costs in the regions are high, comprising 23–43% of household income. Only 4 out of 10 food groups (fish products, cereals, sugar, plant oil are consumed in sufficient amounts. The consumption of milk products, eggs, vegetables, potatoes, fruits (and berries is severely low in a majority of the selected regions. There are high levels of biological contamination of food in many regions. The biological and chemical contamination situation is alarming, especially in Chukotka. Only 7 food pollutants are under regular control; among pesticides, only DDT. Evenki AO and Magadan Oblast have reached peak values in food contaminants compared with other regions. Mercury in local fish has not been analyzed in the majority of the regions. In 3 regions, no monitoring of DDT occurs. Aflatoxins have not been analyzed in 5 regions. Nitrates had the highest percentage in excess of the hygienic threshold in all regions. Excesses of other pollutants in different regions were episodic and as a rule not high. Conclusion.

Full Text Available Despite worldwide advances in science and technology, human well-being of the rich and poor has been threatened by food insecurity. Due to socio-economic and environmental pressures on agriculture, developing countries have faced a shortage of food access and degraded quality of food resources. We argue that traditional ecological knowledge (TEK, when appropriately used and adapted could play a significant role in addressing food security for rural, smallholder farmers. Data were collected in two rural farming communities located in the drought-prone and poverty-stricken Northeast Region of Thailand. Both were situated in diverse ecological settings: one characterized as a subsistent, lowland rice farming community and the other, the upland, all of which were dominated by cash crops. We employed a combined data collection method including in-depth interviews, participant observations, and household surveys to examine household-based food acquisition patterns. We found that the lowland subsistence farming community was endowed with a higher level of TEK and showed a stronger indication of food security than the upland cash-crop focused community. Furthermore, under environmental change, local villagers drew upon TEK to support their way of life. TEK also helped villagers to adapt to new environmental and socio-economic changes, to sustain ecosystem services and agricultural activities, and to build a secure and safe food system. This finding suggests that over-promotion of export-oriented agriculture could leave smallholder farmers and disadvantaged populations in a vulnerable situation. Their food security could be enhanced by the conservation of community-based natural resources with respect given to the role of TEK.

A sudden shortage of physician resources due to overwhelming patient needs can affect the quality of care in the emergency department (ED). Developing effective response strategies remains a challenging research area. We created a novel system using information and communication technology (ICT) to respond to a sudden shortage, and tested the system to determine whether it would compensate for a shortage. Patients (n = 4890) transferred to a level I trauma center in Japan during 2012-2015 were studied. We assessed whether the system secured the necessary physicians without using other means such as phone or pager, and calculated fulfillment rate by the system as a primary outcome variable. We tested for the difference in probability of multiple casualties among total casualties transferred to the ED as an indicator of ability to respond to excessive patient needs, in a secondary analysis before and after system introduction. The system was activated 24 times (stand-by request [n = 12], attendance request [n = 12]) in 24 months, and secured the necessary physicians without using other means; fulfillment rate was 100%. There was no significant difference in the probability of multiple casualties during daytime weekdays hours before and after system introduction, while the probability of multiple casualties during night or weekend hours after system introduction significantly increased compared to before system introduction (4.8% vs. 12.9%, P improvement in the ability to respond to sudden excessive patient needs in multiple causalities. A novel system using ICT successfully secured immediate responses from needed physicians outside the hospital without increasing user workload, and increased the ability to respond to excessive patient needs. The system appears to be able to compensate for a shortage of physician in the ED due to excessive patient transfers, particularly during off-hours.

2014-01-01

The nurse faculty shortage hampers the capacity of the nursing workforce to respond to the demands of the evolving health care system. As a strategy to address the shortage in New Jersey, the Robert Wood Johnson Foundation implemented the New Jersey Nursing Initiative Faculty Preparation Program to prepare nurses for the faculty role. This article highlights program implementation successes and challenges, scholar and faculty perceptions of the program, and provides recommendations for others interested in preparing nurse faculty. This evaluation uses data from scholar surveys and focus groups, interviews with grantees, and grantee reports. Findings suggest that a program that includes generous monetary support, socialization to the nurse faculty role, and formal education courses produces graduates who readily assume a faculty position and are committed to at least a part-time career in nursing education. This evaluation emphasizes the need to carefully design programs that integrate faculty preparation and advanced clinical training. Copyright © 2014 Elsevier Inc. All rights reserved.
Exacerbating Staff Shortages and Student Dissatisfaction? The Impact of AACSB Accreditation on Faculty Recruitment in Australia

2010-09-01

Full Text Available Australian accounting schools are widely perceived to be experiencing a staffing shortage. Many accountingschools are now seeking AACSB accreditation. There has been no consideration in the accounting literatureof how such accreditation might impact on the future ability of accounting schools to attract the ex-practiceaccountants that have traditionally comprised the majority of their faculty recruits. To examine suchimplications, this paper presents an interpretive case study of an Australian business school which is in theprocess of applying for AACSB accreditation. The paper argues that an implication of the increasinglyinflexible work environment driven by AACSB accreditation may be that academia becomes a less attractiveworkplace for ex-practitioner faculty. This may further exacerbate existing academic staff shortages andreduce diversity and professional knowledge within accounting schools, with consequent implications forteaching, student engagement, and industry engagement. This in turn may have long term ramifications forthe ability of the universities to attract students and thus earn the tuition fees on which they currently rely.

2011-01-01

This paper presents rigorous analysis of shortage of canal water supplies, crop water requirements, and groundwater use and its quality in the command of Lower Bari Doab Canal, Pakistan. The annual canal water supplies are 36% less than the crop water requirements. This shortage further increases to 56% if actual canal supplies (averaged over last ten years) are compared with the crop water requirement. The groundwater levels are depleting at the rate of 30 to 40 cm per year in most parts of the LBDC command and this tendency of lowering may increase in future due to further increase in crop water requirements. The analysis of data for the last seven years indicate that quality of groundwater in most parts of LBDC command is generally good (64% of the area) or marginally acceptable (28%) for irrigation use. However, declining trends in groundwater quality are visible and can create long term sustain ability problems if proper remedial actions are not taken well in time. (author)

Cancer is the leading cause of death around the world. Anticancer activities from many functional food sources have been reported in years, but correlation between cancer prevalence and types of food with anticancer activities from crop origin center in the world as well as food source with human migration are unclear. Hunger from food shortage is the cause of early human evolution from Africa to Asia and later into Eurasia. The richest functional foods are found in crop origin centers, housing about 70% in the world populations. Crop origin centers have lower cancer incidence and mortality in the world, especially Central Asia, Middle East, Southwest China, India and Ethiopia. Asia and Africa with the richest anticancer crops is not only the most important evolution base of humans and origin center of anticancer functional crop, but also is the lowest mortality and incidence of cancers in the world. Cancer prevention of early human migrations was associated with functional foods from crop origin centers, especially Asia with four centers and one subcenter of crop origin, accounting for 58% of the world population. These results reveal that coevolution between human's anticancer activities associated with functional foods for crop origin centers, especially in Asia and Africa.
Understanding infants' and children's social learning about foods: previous research and new prospects.

Shutts, Kristin; Kinzler, Katherine D; DeJesus, Jasmine M

2013-03-01

Developmental psychologists have devoted significant attention to investigating how children learn from others' actions, emotions, and testimony. Yet most of this research has examined children's socially guided learning about artifacts. The present article focuses on a domain that has received limited attention from those interested in the development of social cognition: food. We begin by reviewing the available literature on infants' and children's development in the food domain and identify situations in which children evidence both successes and failures in their interactions with foods. We focus specifically on the role that other people play in guiding what children eat and argue that understanding patterns of successes and failures in the food domain requires an appreciation of eating as a social phenomenon. We next propose a series of questions for future research and suggest that examining food selection as a social phenomenon can shed light on mechanisms underlying children's learning from others and provide ideas for promoting healthy social relationships and eating behaviors early in development.

Full Text Available Extreme temperature, frequent and intensive flood, cyclone and other natural disasters due to climate change became acute in Bangladesh and would be severe in future. Besides, water crisis due to shortage of upstream flow and very little rainfall in dry season would affect in a same way. Gradual higher dependency on groundwater irrigation during last few decades created pressure on groundwater even after a huge discharge during rainy season. Using secondary data, this research analyzed the changes in cropping pattern along with a forecast of area to be distributed among various crops in 2029-30 and proposed a re-distribution considering probable crop failure, water crisis and change in food habit. Inherit rice-dominated food habit and government incentive policy encouraged farmers to be concentrated highly on water-intensive rice farming. However, a recent tendency of less rice consumption would encourage crop diversification in future. An incentive policy for farming of diversified crops and their intensification in all crop seasons would be effective to reduce pressure on groundwater and to persuade a balanced food basket in Bangladesh.

Concerns about food allergy and its societal growth are intertwined with the growing advances in plant biotechnology. The knowledge of plant genes and protein structures provides the key foundation to understanding biochemical processes that produce food allergy. Biotechnology offers the prospect of producing low-allergen or allergen null plants that could mitigate the allergic response. Modified low-IgE binding variants of allergens could be used as a vaccine to build immunotolerance in sensitive individuals. The potential to introduce new allergens into the food supply by biotechnology products is a regulatory concern. Copyright © 2010 Elsevier Ltd. All rights reserved.

Severe cases of food allergy account for the majority of the burden in terms of risks, quality of life, and resource expenditure. The traditional approach to these forms has been strict avoidance. More recently, Oral ImmunoTherapy (OIT) has gained a role in their management. However, in severe food allergies OIT is often infeasible. Case reports, observational, and prospective studies have recently proposed different approaches to severe food allergy. The majority of them include the use of biologics. Omalizumab has been the most studied drug for severe food allergies, and its role as adjuvant treatment to OIT is well established. Interest has been raised on other biologics, as dupilumab, reslizumab, and mepolizumab. Toll-like receptor agonists, and gene therapy using adeno-associated virus coding for Omalizumab are promising alternatives. The recent studies are deeply influencing the clinical practice. We review the modifications of the clinical approach to severe food allergies so far available. We indicate the possible evolutions of treatment with biologics in severe food allergies.

Full Text Available The review article reveals the content of the concept of Food Regime, which is little-known in the Russian academic reference. The author monitored and codified the semantic dynamic of the terminological unit from its original interpretations to modern formulations based on the retrospective analysis. The rehabilitation of the academic merits of D. Puchala and R. Hopkins — authors who used the concept Food Regime for a few years before its universally recognized origin and official scientific debut, was accomplished with help of historical and comparative methods. The author implemented the method of ascension from the abstract to the concrete to demonstrating the classification of Food Regimes compiled on the basis of geopolitical interests in the sphere of international production, consumption, and distribution of foodstuffs. The characteristic features of historically formed Food Regime were described in the chronological order, as well as modern tendencies possessing reformist potential were identified. In particular, it has been established that the idea of Food Sovereignty (which is an alternative to the modern Corporate Food Regime is the subject for acute academic disputes. The discussion between P. McMichael P. and H. Bernstein devoted to the “peasant question” — mobilization frame of the Food Sovereignty strategy was analyzed using the secondary data processing method. Due to the critical analysis, the author comes to the conclusion that it is necessary to follow the principles of the Food Sovereignty strategy to prevent the catastrophic prospects associated with ecosystem degradation, accelerated erosion of soils, the complete disappearance of biodiversity and corporate autoc racy successfully. The author is convinced that the idea of Food Sovereignty can ward off energetic liberalization of nature, intensive privatization of life and rapid monetization of unconditioned human reflexes.

Food supplementation does not increase demographic rates in a passerine species of conservation concern

Directory of Open Access Journals (Sweden)

Innes M.W. Sim

2015-05-01

Full Text Available Numerous studies have examined the effects of the provision of supplementary food on aspects of avian reproductive success, but far fewer have gone on to examine the potential positive effects of food supplementation on the demographic rates which are key for population growth rate. Testing for potential effects of food shortage on vital rates is likely to be particularly important in species of high conservation concern, where populations are particularly small, isolated or decreasing rapidly. Here we test the effects of the provision of supplementary food on reproductive success, body condition at fledging and post-fledging survival of ring ouzels (Turdus torquatus, a species of high conservation concern in the UK. However, food supplementation had no detectable effect on any of these parameters. There was no significant difference in return rates of fed and unfed fledglings in the year following hatching, and most post-fledging mortality was apparently caused by predation by raptors and mustelids. We conclude that the supply of invertebrate food sources for nestlings was not a major limiting factor in our study area, at least during this two-year study. Further studies are required to quantify the precise mix of habitats used by ring ouzels, at the appropriate scale, which provide concealment from predators and access to food supplies throughout the spring and summer months.

Reduce, reuse and recycle: A green solution to Canada's medical isotope shortage

International Nuclear Information System (INIS)

Galea, R.; Ross, C.; Wells, R.G.

2014-01-01

Due to the unforeseen maintenance issues at the National Research Universal (NRU) reactor at Chalk River and coincidental shutdowns of other international reactors, a global shortage of medical isotopes (in particular technetium-99m, Tc-99m) occurred in 2009. The operation of these research reactors is expensive, their age creates concerns about their continued maintenance and the process results in a large amount of long-lived nuclear waste, whose storage cost has been subsidized by governments. While the NRU has since revived its operations, it is scheduled to cease isotope production in 2016. The Canadian government created the Non-reactor based medical Isotope Supply Program (NISP) to promote research into alternative methods for producing medical isotopes. The NRC was a member of a collaboration looking into the use of electron linear accelerators (LINAC) to produce molybdenum-99 (Mo-99), the parent isotope of Tc-99m. This paper outlines NRC’s involvement in every step of this process, from the production, chemical processing, recycling and preliminary animal studies to demonstrate the equivalence of LINAC Tc-99m with the existing supply. This process stems from reusing an old idea, reduces the nuclear waste to virtually zero and recycles material to create a green solution to Canada's medical isotope shortage. - Highlights: • Commercial power electron accelerators are realistic option to produce 99 Mo. • Could cover national demand of Canada. • Demonstrate LINAC- 99 Mo as environmental and economical solution to isotope crisis. • Demonstrate LINAC- 99m Tc to be clinically equivalent to current fission- 99m Tc supply

2016-01-01

In 2011, Fukushima was struck by a triple disaster: an earthquake, tsunamis, and a nuclear accident. In the aftermath, there was much fear among hospital staff members about radiation exposure and many staff members failed to report to work. One objective is to measure this shortage in hospital staff and another is to compare the difference in recovery by hospital types and by categories of hospital staff. The monthly records of the number of staff members from May 2011 to September 2012 were extracted anonymously from the records of 7 local hospitals in the Soso district in Fukushima. Change in the number of staff was analyzed. Staff shortages at hospitals reached a maximum within one month after the disaster (47% reported to work). The shortage of clerks was the most severe (38% reported to work), followed by nurses (48% reported to work). The shortages remained even 18 months after the disaster. After a disaster in which the damage to hospital functions surpasses the structural damage, massive support of human resources in the acute phase and a smaller volume of support in the mid-term phase appear to be required, particularly for non-medical staff.

It is a great pleasure for me to speak here at Chatham House. I am aware that this is a very knowledgeable audience. Some of you are leading world experts in issues which I will touch upon today, such as nuclear non-proliferation. I would therefore like to start by talking about some aspects of the work of the International Atomic Energy Agency which are less well known. We are much more than the ''world's nuclear watchdog'', the common media shorthand for our role. The IAEA makes important contributions to tackling fundamental global problems such as food security, water and energy shortages and climate change, as well as in the area of human health. Through our technical cooperation programme, we help to make nuclear technology available to our Member States for peaceful purposes - for example, cancer control in developing countries. This is a major priority for me personally. Some 70 percent of cancer cases are now diagnosed in developing countries. Most of them are ill-prepared to respond. There is a shortage of around 5,000 radiotherapy machines in low- and middle-income countries. There are not enough well-trained specialists. As a result, around three-quarters of patients are diagnosed too late for effective treatment. This means that hundreds of thousands of people do not have access to treatment that could save their lives. The Agency supports over 130 projects in cancer diagnosis, management and treatment. Oncology and radiotherapy centres are being established with our support in countries such as Afghanistan, Eritrea and Mozambique. We provide extensive training to health professionals. One of my major goals is to establish a Cancer Training Centre at our laboratory complex outside Vienna within the next few years. Our nuclear applications laboratories are doing pioneering work related to human and animal health, food security and safety, agriculture, and environmental monitoring

Nursing shortage is a global issue that which affects oncology nursing. Oncology nurses are more prone to experience job dissatisfaction, stress and burnout when they work in units with poor staffing. There is thus a need for greater understanding of the relationship between the nursing shortage and nursing outcomes in oncology/haematology settings. This review aimed to establish the best available evidence concerning the relationship between the nursing shortage and nurses' job satisfaction, stress and burnout levels in oncology/haematology settings; and to make recommendations for practice and future research. Types of participants: This review considered studies that included oncology registered nurses (RNs) who were more than 18 years of age and worked in either inpatient or outpatient oncology/haematology wards or units for the adult or paediatric patients.Types of intervention: This review considered studies that evaluated the relationship between the nursing shortage and nurses' job satisfaction, stress and burnout levels in oncology/haematology settings.Types of outcomes: This review included studies that measured job satisfaction, stress and burnout levels using different outcomes measures. Job satisfaction was determined by the Measure of Job Satisfaction scale, the Misener Nurse Practitioner Job Satisfaction Scale and the Likert scale, stress by the Pediatric Oncology Nurse Stressor Questionnaire and burnout by the Maslash Burnout Inventory scale.Types of studies: This review included descriptive/descriptive-correlational studies which were published in English. The search strategy sought to identify published and unpublished studies conducted between 1990 and 2010. Using a three-step search strategy, the following databases were accessed: CINAHL, Medline, Scopus, ScienceDirect, PsycInfo, PsycArticles, Web of Science, The Cochrane Library, Proquest and Mednar. Two independent reviewers assessed each paper for methodological validity prior to inclusion in

Fast-food consumption has increased greatly in the USA during the past three decades. However, the effect of fast food on risk of obesity and type 2 diabetes has received little attention. We aimed to investigate the association between reported fast-food habits and changes in bodyweight and insulin resistance over a 15-year period in the USA. Participants for the CARDIA study included 3031 young (age 18-30 years in 1985-86) black and white adults who were followed up with repeated dietary assessment. We used multiple linear regression models to investigate the association of frequency of fast-food restaurant visits (fast-food frequency) at baseline and follow-up with 15-year changes in bodyweight and the homoeostasis model (HOMA) for insulin resistance. Fast-food frequency was lowest for white women (about 1.3 times per week) compared with the other ethnic-sex groups (about twice a week). After adjustment for lifestyle factors, baseline fast-food frequency was directly associated with changes in bodyweight in both black (p=0.0050) and white people (p=0.0013). Change in fast-food frequency over 15 years was directly associated with changes in bodyweight in white individuals (pfast-food restaurant use at baseline and follow-up (n=203), those with frequent (more than twice a week) visits to fast-food restaurants at baseline and follow-up (n=87) gained an extra 4.5 kg of bodyweight (p=0.0054) and had a two-fold greater increase in insulin resistance (p=0.0083). Fast-food consumption has strong positive associations with weight gain and insulin resistance, suggesting that fast food increases the risk of obesity and type 2 diabetes.

Coping with chaos: unpredictable food supplies intensify torpor use in an arid-zone marsupial, the fat-tailed dunnart ( Sminthopsis crassicaudata)

Munn, Adam J.; Kern, Pippa; McAllan, Bronwyn M.

2010-06-01

The severity, duration and amplitude of extreme weather events are forecast to intensify with current climate trends, over both long (e.g. seasonal) and short (e.g. daily) time-scales. As such, the predictability of food supplies for many small endotherms is likely to become increasingly important. Numerous small mammals and birds combat food shortages using torpor, a controlled reduction in metabolic rate and body temperature that helps lower their daily energy requirements. As such, torpor often has been cited as a key feature allowing some small endotherms to survive highly unpredictable climates, such as tropics or dry deserts, but mensurative demonstrations of this are lacking. We have shown here that when a small desert marsupial, the fat-tailed dunnart ( Sminthopsis crassicaudata), is offered unpredictable levels of daily food, they increase frequency of daily torpor and length of bouts compared with animals offered ad libitum food, but this was not found for animals offered a 70% food-restricted diet. Our data suggest that simple food restriction may not be sufficient for evaluating the efficacy of torpor as a strategy for managing unpredictable climates.

2009-01-01

Interest in the areas of food animals (FA) and veterinary public health (VPH) appears to be declining among prospective students of veterinary medicine. To address the expected shortage of veterinarians in these areas, the Utrecht Faculty of Veterinary Medicine has developed an admissions procedure to select undergraduates whose aptitude and interests are suited to these areas. A study using expert meetings, open interviews, and document analysis identified personal characteristics that distinguished veterinarians working in the areas of FA and VPH from their colleagues who specialized in companion animals (CA) and equine medicine (E). The outcomes were used to create a written selection tool. We validated this tool in a study among undergraduate veterinary students in their final (sixth) year before graduation. The applicability of the tool was verified in a study among first-year students who had opted to pursue either FA/VPH or CA/E. The tool revealed statistically significant differences with acceptable effect sizes between the two student groups. Because the written selection tool did not cover all of the differences between the veterinarians who specialized in FA/VPH and those who specialized in CA/E, we developed a prestructured panel interview and added it to the questionnaire. The evaluation of the written component showed that it was suitable for selecting those students who were most likely to succeed in the FA/VPH track.

The use of gamma and fast electron radiations for food preservation is described. Examples are given of the application of ionizing radiation for retarding potato germination, onion growth, and fruit ripening, for limiting the action of microorganisms, and removing salmonella from meat products. The method has remarkable prospects although it may not be considered to be a general-purpose method. Geographic and economic conditions should always be taken into consideration. (J.P.)

MRI of plants and foods

2013-04-01

The importance and prospects for MRI as applied to intact plants and to foods are presented in view of one of humanity's most pressing concerns, the sustainable and healthy feeding of a worldwide increasing population. Intact plants and foods have in common that their functionality is determined by complex multiple length scale architectures. Intact plants have an additional level of complexity since they are living systems which critically depend on transport and signalling processes between and within tissues and organs. The combination of recent cutting-edge technical advances and integration of MRI accessible parameters has the perspective to contribute to breakthroughs in understanding complex regulatory plant performance mechanisms. In food science and technology MRI allows for quantitative multi-length scale structural assessment of food systems, non-invasive monitoring of heat and mass transport during shelf-life and processing, and for a unique view on food properties under shear. These MRI applications are powerful enablers of rationally (re)designed food formulations and processes. Limitations and bottlenecks of the present plant and food MRI methods are mainly related to short T2 values and susceptibility artefacts originating from small air spaces in tissues/materials. We envisage cross-fertilisation of solutions to overcome these hurdles in MRI applications in plants and foods. For both application areas we witness a development where MRI is moving from highly specialised equipment to mobile and downscaled versions to be used by a broad user base in the field, greenhouse, food laboratory or factory.

Education and the food-systems veterinarian: the impact of new information technologies.

Science.gov (United States)

Bernardo, Theresa M

2006-01-01

Food systems educators face a double challenge: (1) the inherent change in scope and perspective from raising animals to producing safe food in an environmentally conscientious manner; and (2) the unprecedented demand for higher education, both nationally and internationally. In the modern world, small numbers of producers are capable of feeding a growing population. As demographics have shifted from rural to urban areas, more global livelihoods are derived from manufacturing and services than from agriculture. Education, as one of those services, is accounting for an increasing percentage of world trade, through the physical translocation of students and, more recently, through online education. Within the veterinary realm, colleges outside the United States seek accreditation to better compete for students, and there is increasing pressure from private schools. Today's food systems require a high level of veterinary expertise, with specialization in a particular production system as well as the ability to contribute as part of a larger team that can address economic, bio-security, biological-waste, animal-welfare, food-safety, and public-health concerns. The need for different expertise from food systems specialists (indeed, shortages of all types of veterinary specialists), combined with global competition in education, is a call to action for the veterinary profession. This is an opportunity to revisit and reorganize the delivery of veterinary education, making use of new collaborative technologies for greater efficiency and effectiveness.
Applications of PTR-MS in food flavour research: recent progress and prospects

International Nuclear Information System (INIS)

Yeretzian, C.; Pollien, P.; Jordan, A.; Graus, M.; Lindinger, W.

2002-01-01

Food products all along the food chain from raw material to final products continuously emit volatile organic compounds (VOs), which are related to important properties of the product itself such as flavor, age, or safety among others. Several analytical techniques for sampling and analysing the head space (HS) of food has been developed, however the proton-transfer-reaction mass spectrometry (PTR-MS) has the particularity to be able to work on real time-basis. By applying PTR-MS two qualitatively distinct types of information were obtained: HS profiles can be averaged over a given time window to yield concentration vs. mass spectra (static data). Such spectra can be used to asses authenticity, monitor deviation in production from a reference or classify product. Alternatively, temporal changes can be analysed via time-intensity plots (dynamic data). As example soluble coffee data is given. (nevyjel)
The analysis on the extreme water shortage event in Hangzhou in 1247 AD and its natural and social backgrounds

2017-04-01

Yangtze River Delta locating in the north subtropics of China, is famous for numerous rivers and lakes. Because of East Asian monsoon rainfall, flood is always the most primary disaster in this area during the past 2000 years. However, there were also several extreme water shortage events in the history. Example in Hangzhou in 1247 AD was such a typical year in the area. In the paper, the severity of this extreme event and the closely tied spatiotemporal variation of drought in Yangtze River Delta was quantitatively analyzed on the basis of documentary records during Southern Song Dynasty. Furtherly, its natural and social backgrounds was discussed. The result s are summarized as follows: 1) Wells, canals and West Lake of Hangzhou dried up in 1247 AD. The water level of canals was about 1.32-2.64 m lower than that in the normal year. The reduction of storage capacity in West Lake was 21 million stere or so. 2) The droughts in Yangtze River Delta was moderate on the whole, but that in the west of Zhejiang Province was severe. The drought in Hangzhou lasted from the 2nd lunar month to the end of this year. 3) The water shortage event was closely related to the quick going north and farther northern location of summer rain belt. The descending sea-level weakening the tide in Qiantang River, can also reduce the supply of water resources. 4) The quick growth of urban population, excessive aquaculture, and ineffective government supervision played an important social role in the process of this event. In the all, this extreme water shortage event was the result of both natural and social factors. This research is very helpful for the futuristic water resource forecast in Yangtze River Delta, and it also affords us lessons on the risk management and heritage conservation that merit attention. Key Words: Hangzhou, 1247 AD, water shortage, canal, West Lake, natural factors, social factors
Predicted shortage of vascular surgeons in the United Kingdom: A matter for debate?

Harkin, D W; Beard, J D; Shearman, C P; Wyatt, M G

2016-10-01

Vascular surgery became a new independent surgical specialty in the United Kingdom (UK) in 2013. In this matter for debate we discuss the question, is there a "shortage of vascular surgeons in the United Kingdom?" We used data derived from the "Vascular Surgery United Kingdom Workforce Survey 2014", NHS Employers Electronic Staff Records (ESR), and the National Vascular Registry (NVR) surgeon-level public report to estimate current and predict future workforce requirements. We estimate there are approximately 458 Consultant Vascular Surgeons for the current UK population of 63 million, or 1 per 137,000 population. In several UK Regions there are a large number of relatively small teams (3 or less) of vascular surgeons working in separate NHS Trusts in close geographical proximity. In developed countries, both the number and complexity of vascular surgery procedures (open and endovascular) per capita population is increasing, and concerns have been raised that demand cannot be met without a significant expansion in numbers of vascular surgeons. Additional workforce demand arises from the impact of population growth and changes in surgical work-patterns with respect to gender, working-life-balance and 7-day services. We predict a future shortage of Consultant Vascular Surgeons in the UK and recommend an increase in training numbers and an expansion in the UK Consultant Vascular Surgeon workforce to accommodate population growth, facilitate changes in work-patterns and to create safe sustainable services.

2013-01-01

Food insecurity is turning out to be one of the worst crises of world in future. Developing countries are especially considered vulnerable to be hit most severely by this impending danger. Resource scarce regions of Pakistan are also included in the list of marginalized areas where population is not able to manage its food by herself. The present study was designed to analyze the state of household food security concerns and identify managing strategies for dealing with shortage of food patterns in Northern Pakistan. The research was based upon a survey of randomly selected two districts. Both qualitative and quantitative research methods were used for data collection. The results indicated that prices of food items were very high. It also delineated that lack of irrigational water; limited market access, and high cost of fertilizers were leading production related constraints. As a resort to these constraints and due to low output from the food crops there was found a shift from subsistence to cash seeking cropping patterns of the growers. This increase in income was perceived as a mean to ensure household food security. Furthermore, at household level the respondents expressed to reduce their expenses on the agricultural inputs in future. (author)

Full Text Available Phenotypic traits vary greatly within populations and can have a significant influence on aspects of performance. The present study aimed to investigate the effects of individual variation in standard metabolic rate (SMR on growth rate and tolerance to food deprivation in juvenile Chinese crucian carp (Carassius auratus under varying levels of food availability. To address this issue, 19 high and 16 low SMR individuals were randomly assigned to a satiation diet for 3 weeks, whereas another 20 high and 16 low SMR individuals were assigned to a restricted diet (approximately 50% of satiation for the same period. Then, all fish were completely food-deprived for another 3 weeks. High SMR individuals showed a higher growth rate when fed to satiation, but this advantage of SMR did not exist in food-restricted fish. This result was related to improved feeding efficiency with decreased food intake in low SMR individuals, due to their low food processing capacity and maintenance costs. High SMR individuals experienced more mass loss during food deprivation as compared to low SMR individuals. Our results here illustrate context-dependent costs and benefits of intraspecific variation in SMR whereby high SMR individuals show increased growth performance under high food availability but had a cost under stressful environments (i.e. food shortage.

Dietary assessment methods are important tools for nutrition research. Online dietary assessment tools have the potential to become invaluable methods of assessing dietary intake because, compared with traditional methods, they have many advantages including the automatic storage of input data and the immediate generation of nutritional outputs. The aim of this study was to develop an online food frequency questionnaire (FFQ) for dietary data collection in the "Food4Me" study and to compare this with the validated European Prospective Investigation of Cancer (EPIC) Norfolk printed FFQ. The Food4Me FFQ used in this analysis was developed to consist of 157 food items. Standardized color photographs were incorporated in the development of the Food4Me FFQ to facilitate accurate quantification of the portion size of each food item. Participants were recruited in two centers (Dublin, Ireland and Reading, United Kingdom) and each received the online Food4Me FFQ and the printed EPIC-Norfolk FFQ in random order. Participants completed the Food4Me FFQ online and, for most food items, participants were requested to choose their usual serving size among seven possibilities from a range of portion size pictures. The level of agreement between the two methods was evaluated for both nutrient and food group intakes using the Bland and Altman method and classification into quartiles of daily intake. Correlations were calculated for nutrient and food group intakes. A total of 113 participants were recruited with a mean age of 30 (SD 10) years (40.7% male, 46/113; 59.3%, 67/113 female). Cross-classification into exact plus adjacent quartiles ranged from 77% to 97% at the nutrient level and 77% to 99% at the food group level. Agreement at the nutrient level was highest for alcohol (97%) and lowest for percent energy from polyunsaturated fatty acids (77%). Crude unadjusted correlations for nutrients ranged between .43 and .86. Agreement at the food group level was highest for "other

To describe the research methods for the development of a new open source, cross-platform tool which processes data from the European Prospective Investigation into Cancer and Nutrition Norfolk Food Frequency Questionnaire (EPIC-Norfolk FFQ). A further aim was to compare nutrient and food group values derived from the current tool (FETA, FFQ EPIC Tool for Analysis) with the previously validated but less accessible tool, CAFÉ (Compositional Analyses from Frequency Estimates). The effect of text matching on intake data was also investigated. Cross-sectional analysis of a prospective cohort study-EPIC-Norfolk. East England population (city of Norwich and its surrounding small towns and rural areas). Complete FFQ data from 11 250 men and 13 602 women (mean age 59 years; range 40-79 years). Nutrient and food group intakes derived from FETA and CAFÉ analyses of EPIC-Norfolk FFQ data. Nutrient outputs from FETA and CAFÉ were similar; mean (SD) energy intake from FETA was 9222 kJ (2633) in men, 8113 kJ (2296) in women, compared with CAFÉ intakes of 9175 kJ (2630) in men, 8091 kJ (2298) in women. The majority of differences resulted in one or less quintile change (98.7%). Only mean daily fruit and vegetable food group intakes were higher in women than in men (278 vs 212 and 284 vs 255 g, respectively). Quintile changes were evident for all nutrients, with the exception of alcohol, when text matching was not executed; however, only the cereals food group was affected. FETA produces similar nutrient and food group values to the previously validated CAFÉ but has the advantages of being open source, cross-platform and complete with a data-entry form directly compatible with the software. The tool will facilitate research using the EPIC-Norfolk FFQ, and can be customised for different study populations.

Although the last decade has seen increased access to antiretroviral therapy across the developing world, widespread food insecurity and undernutrition continue to compromise an effective response to the AIDS epidemic. Limited evidence exists on the potential benefit of food security and nutrition interventions to people living with HIV (PLHIV). We capitalized on an existing intervention to PLHIV in Uganda and conducted a prospective quasi-experimental study evaluating the impact of a monthly household food basket, provided to food insecure antiretroviral therapy-naive PLHIVs for 12 months. The outcomes of interest measured at baseline and follow-up were nutritional status [body mass index; mid-upper arm circumference and hemoglobin (Hb) concentrations], disease severity (CD4 count), and 2 measures of food security: diet quality (Individual Dietary Diversity Score) and food access (Household Food Insecurity Access Scale). We used difference-in-difference propensity score matching to examine the impact of food assistance. Over 12 months, food assistance significantly increased body mass index by 0.6 kg/m (P Insecurity Access Scale, by 2.1 points (P insecurity.

In many inventory models uncertainty is due to fuzziness and fuzziness is the closed possible approach to reality. In this paper, we proposed a fuzzy inventory model with acceptable shortage which is completely backlogged. We fuzzily the carrying cost, backorder cost and ordering cost using Triangular and Trapezoidal fuzzy numbers to obtain the fuzzy total cost. The purpose of our study is to defuzzify the total profit function by Graded Mean Integration Value Method. Further a numerical example is also given to demonstrate the developed crisp and fuzzy models.

Food insecurity is a key social and health issue among persons living with HIV (PLHIV). Food insecurity oftentimes co-occurs with substance use, but little is known about the relationship between tobacco use and food insecurity particularly among PLHIV. In this study, we prospectively examined the association of cigarette smoking with food insecurity in a cohort of 108 individuals seeking vocational rehabilitation services. Over the 12-month study period, smokers at baseline reported consistently higher levels of food insecurity compared to non-smokers. Smoking remained an independent risk factor for greater food insecurity, controlling for sociodemographic characteristics and known confounders (e.g., substance use, depression). Food insecurity is a key structural and socioeconomic barrier that may partially explain HIV-related health disparities observed among smokers. Further research is needed to characterize the bio-behavioral mechanisms linking smoking and food insecurity as well as test whether smoking cessation can reduce food insecurity in PLHIV who smoke.

Demonstration project: Load management on the user side at power shortages

International Nuclear Information System (INIS)

Lindskoug, Stefan

2005-10-01

The risk for power shortages during extreme cold weather has increased in Sweden. Comments are made that high electricity spot prices are important for holding down the demand. Through the consumers' higher price sensitivity, the electricity system can be operated with lower reserve capacity. The objective of the demonstration project is to show methods for reducing the electricity demand at the national level at high spot prices. An important prerequisite is that the measures must be profitable for all parties involved. Four separate studies were made, two concerning households, one industry and one for the district heating sector. The conclusion from the studies is that load management on the customer's side is an economic alternative to investment in new production capacity
Keystones affecting sub-Saharan Africa's prospects for achieving food security through balanced diets.

May, Julian

Socio-economic dynamics determine the transition from diets characterized by the risk of famine, to those characterized by the risk of diet-related non-communicable disease (DR-NCD). This transition is of particular concern in Sub-Saharan Africa (SSA) in which key socio-economic interactions that influence diet include economic growth and rapid urbanization; inequality and a growing middle class; and obesogenic food environments and an increasing prevalence of DR-NCD. In each case, countries in SSA are among those experiencing the most rapid change in the world. These interactions, styled as 'keystones', affect the functioning of other components of the food system and the diets that result. Data from the wealthiest quartile of countries in SSA suggest that these keystones may be increasing the risk of DR-NCD, widening inequalities in health outcomes due to unbalanced diets. To address this, new consumer and government capabilities that address these keystones are required. Food sensitive urban planning, supporting food literacy and fiscal management of consumption are examples. Copyright © 2017 Elsevier Ltd. All rights reserved.
Food composition database development for between country comparisons

Full Text Available Abstract Nutritional assessment by diet analysis is a two-stepped process consisting of evaluation of food consumption, and conversion of food into nutrient intake by using a food composition database, which lists the mean nutritional values for a given food portion. Most reports in the literature focus on minimizing errors in estimation of food consumption but the selection of a specific food composition table used in nutrient estimation is also a source of errors. We are conducting a large prospective study internationally and need to compare diet, assessed by food frequency questionnaires, in a comparable manner between different countries. We have prepared a multi-country food composition database for nutrient estimation in all the countries participating in our study. The nutrient database is primarily based on the USDA food composition database, modified appropriately with reference to local food composition tables, and supplemented with recipes of locally eaten mixed dishes. By doing so we have ensured that the units of measurement, method of selection of foods for testing, and assays used for nutrient estimation are consistent and as current as possible, and yet have taken into account some local variations. Using this common metric for nutrient assessment will reduce differential errors in nutrient estimation and improve the validity of between-country comparisons.

Khanna, Aditi; Gautam, Prerna; Jaggi, Chandra K.

2016-03-01

Supply chain management has become a critical issue for modern business environments. In today's world of cooperative decision-making, individual decisions in order to reduce inventory costs may not lead to an overall optimal solution. Coordination is necessary among participants of supply chain to achieve better performance. There are legitimate and important efforts from the vendor to enhance the relation with buyer; one such effort is offering trade credit which has been a driver of growth and development of business between them. The cost of financing is a core consideration in effective financial management, in general and in context of business. Also, due to imperfect production a vendor may produce defective items which results in shortages. Motivated with these aspects, an integrated vendor-buyer inventory model is developed for imperfect quality items with allowable shortages; in which the vendor offers credit period to the buyer for payment. The objective is to minimize the total joint annual costs incurred by the vendor and the buyer by using integrated decision making approach. The expected total annual integrated cost is derived and a solution procedure is provided to find the optimal solution. Numerical analysis shows that the integrated model gives an impressive cost reduction, in comparison to independent decision policies by the vendor and the buyer.

Ultraprocessed food consumption has increased in the past decade. Evidence suggests a positive association between ultraprocessed food consumption and the incidence of overweight and obesity. However, few prospective studies to our knowledge have investigated this potential relation in adults. We evaluated the association between ultraprocessed food consumption and the risk of overweight and obesity in a prospective Spanish cohort, the SUN (University of Navarra Follow-Up) study. We included 8451 middle-aged Spanish university graduates who were initially not overweight or obese and followed up for a median of 8.9 y. The consumption of ultraprocessed foods (defined as food and drink products ready to eat, drink, or heat and made predominantly or entirely from processed items extracted or refined from whole foods or synthesized in the laboratory) was assessed with the use of a validated semiquantitative 136-item food-frequency questionnaire. Cox proportional hazards models were used to estimate adjusted HRs and 95% CIs for incident overweight and obesity. A total of 1939 incident cases of overweight and obesity were identified during follow-up. After adjustment for potential confounders, participants in the highest quartile of ultraprocessed food consumption were at a higher risk of developing overweight or obesity (adjusted HR: 1.26; 95% CI: 1.10, 1.45; P-trend = 0.001) than those in the lowest quartile of consumption. Ultraprocessed food consumption was associated with a higher risk of overweight and obesity in a prospective cohort of Spanish middle-aged adult university graduates. Further longitudinal studies are needed to confirm our results. This trial was registered at clinicaltrials.gov as NCT02669602. © 2016 American Society for Nutrition.
The crisis in leadership in the context of the nursing shortage and the increasing prevalence of nursing unions

Full Text Available Latisha L Balogh-RobinsonMarist College, School of Global and Professional Programs, Poughkeepsie, NY, USAAbstract: Developing nurse leaders in a unionized environment presents unique challenges that are beyond those traditionally experienced in nonunion settings. This literature review examines multiple factors contributing to increasing nursing union membership, including population aging, the nursing shortage, and the relationship between leadership and staff engagement. Current trends in succession planning and leadership development are also highlighted. Job dissatisfaction related to the inability to provide quality care in the context of a protracted nursing shortage and current health care trends is identified as the driver in nursing union growth. The discussion that follows assumes current trends in nursing unionization will continue and proposes that adversarial relationships between management and union nurses will further amplify the dearth in leadership by reducing the pool of nurses willing to leave the union for nonunion leadership roles.Keywords: succession planning, baby boomer, staff engagement, population aging

Infants with eczema and sensitization to foods are recommended skin care and, if food allergy is proven, an elimination diet. Although most of these children tolerate foods before 3 yr of age, some children experience prolonged food allergy. To our knowledge, no prospective study has investigated the cytokine profile in food-sensitized eczematous children with prolonged food intolerance. The aim of the study was to prospectively investigate the development of cytokine production induced by food allergen in food-sensitized eczematous children who, at 4(1/2) yr of age, were allergic or tolerant to egg or milk. Twenty-one eczematous infants, [age 5 (3-10) months; median and range], sensitized to egg and/or milk were included, put on elimination diet and followed prospectively. At 4(1/2) yr of age, the children were defined as tolerant or allergic to egg and/or milk based on open or double-blind placebo-controlled food challenges. Peripheral blood mononuclear cells (PBMC) were isolated from the children on inclusion, after 6 wk of elimination diet, and at 3 and 4(1/2) yr of age. Ovalbumin, beta-lactoglobulin and tetanus toxoid-induced IL-4, -5, -10, -13 and IFN-gamma production from PBMC were analyzed with enzyme-linked immunosorbent assay. The IFN-gamma and IL-5 secretion induced by food allergen at 4(1/2) yr was higher in cell cultures from children who were allergic to egg or milk than in tolerant children. In food-allergic children, the levels of IFN-gamma and IL-5 were higher at 4(1/2) yr compared with inclusion levels, but this increase was generally not observed in the tolerant children who consumed milk and egg. In conclusion, immune cells from food-allergic children on an elimination diet respond with up-regulated T helper 1 and T helper 2 cytokine secretion induced by food allergen. We hypothesize that allergen elimination may influence the regulatory mechanisms maintaining balanced immune responses to innocuous food antigens.

Epidemiological studies conducted thus far have mainly used a single-nutrient approach which may not be sufficient in detecting diet-cancer relationships. The aim of the study was to examine the association of a food pattern based on explained variations in fatty acid intake by means of reduced rank regression with breast cancer risk. Study participants were female subjects (n 15,351) of the European Prospective Investigation into Cancer and Nutrition (EPIC)-Potsdam Study free of cancer at baseline and with complete dietary and outcome information followed for an average of 6.0 years. Among those, 137 incident cases of invasive breast cancer were identified. We identified a food pattern characterized by low consumption of bread, and fruit juices, and high consumption of processed meat, fish, butter and other animal fats, and margarine explaining >42 % of total variation in fatty acid intake (SFA, MUFA, n-3 PUFA, n-6 PUFA). Intake of all four fatty acid fractions was positively associated with the pattern score. Adherence to this food pattern adjusted for covariates was associated with a two-fold risk (hazard ratio 2.00; 95 % CI 1.30, 3.09) of breast cancer comparing extreme tertiles of the pattern score. There was no evidence of effect modification by menopausal status, overweight status and use of hormone replacement therapy, respectively. In conclusion, a food pattern characterized by high-fat food choices was significantly associated with increased risk of breast cancer. Given that the food pattern was high in all fatty acid fractions, we found evidence for total dietary fat rather than for specific fatty acids to be associated with breast cancer risk.

The prevalence of IgE-mediated food allergy and anaphylaxis has risen rapidly in developed countries, and countries with rapid industrialization may follow. Therapies include elimination diets, Oral ImmunoTherapy, and the administration of biologics, but high serum IgE levels may preclude their use. Consequently, decreasing IgE becomes a rational approach and could be obtained by immunoapheresis. The aim of this review is to evaluate the rationale and advantages of immunoapheresis. The majority of the available adsorbers remove aspecifically all classes of immunoglobulins. Recently, IgE-specific adsorbers have been approved. Data on immunoapheresis for the treatment of allergic diseases with pathologically elevated IgE levels are emerging. In atopic dermatitis, this therapy alone seems to be beneficial. IgE-selective apheresis appears to be sufficient to reduce the risk of anaphylaxis in multiple food allergy (MFA) and, when IgE titers are high, to open the way to treatment with Omalizumab. Prospective studies, with well designed protocols, are needed to assess the efficacy, tolerability, and cost-effectiveness of immunoapheresis in the field of food allergy.

The World Health Organization (WHO) has deemed that there is enough evidence to recommend the elimination of industrially produced trans-fatty acids (TFA) from the food supply. This article evaluates government-led public health strategies in countries in Latin America and the Caribbean (LAC), and factors perceived to affect following WHO's recommendation to eliminate industrially produced TFA. Descriptive, prospective multiple case studies integrated data from open-ended questionnaires to representatives of ministries of health, and systematic review of internal and publicly available documents in 13 LAC countries. Overall, government efforts to follow WHO recommendations have not been well co-ordinated throughout the region. Evidence for this includes the lack of standardization of TFA definitions. For example, some countries exclude naturally occurring TFA from the definitions, whereas others leave the option open to their inclusion. As a consequence, the criteria for trans-free nutrient claims and labelling requirements are inconsistent across the region. Government-led strategies varied from banning or limiting TFA content in the food supply to voluntary labelling of TFA. The identified challenges to the implementation of policies to reduce TFA include the shortage of information on TFA content of diets and foods, consumer unawareness of TFA and lack of monitoring and surveillance. The identified enabling factors were intersectoral collaboration with industry, mandatory labelling regulation and international and national visibility of the topic, which facilitated reduction of TFA content. A co-ordinated effort is required to achieve virtual elimination of all TFA in the region, as recommended by WHO. Standardization of the definition of TFA across the region would facilitate regulation, consumer education efforts and monitoring and surveillance efforts. Simultaneously, countries need to determine their level of exposure to TFA through the implementation of
Feeding and stocking up: radio-labelled food reveals exchange patterns in ants.

Food sharing is vital for a large number of species, either solitary or social, and is of particular importance within highly integrated societies, such as in colonial organisms and in social insects. Nevertheless, the mechanisms that govern the distribution of food inside a complex organizational system remain unknown. Using scintigraphy, a method developed for medical imaging, we were able to describe the dynamics of food-flow inside an ant colony. We monitored the sharing process of a radio-labelled sucrose solution inside a nest of Formica fusca. Our results show that, from the very first load that enters the nest, food present within the colony acts as negative feedback to entering food. After one hour of the experiments, 70% of the final harvest has already entered the nest. The total foraged quantity is almost four times smaller than the expected storage capacity. A finer study of the spatial distribution of food shows that although all ants have been fed rapidly (within 30 minutes), a small area representing on average 8% of the radioactive surface holds more than 25% of the stored food. Even in rather homogeneous nests, we observed a strong concentration of food in few workers. Examining the position of these workers inside the nest, we found heavily loaded ants in the centre of the aggregate. The position of the centre of this high-intensity radioactive surface remained stable for the three consecutive hours of the experiments. We demonstrate that the colony simultaneously managed to rapidly feed all workers (200 ants fed within 30 minutes) and build up food stocks to prevent food shortage, something that occurs rather often in changing environments. Though we expected the colony to forage to its maximum capacity, the flow of food entering the colony is finely tuned to the colony's needs. Indeed the food-flow decreases proportionally to the food that has already been harvested, liberating the work-force for other tasks.
How 21st century droughts affect food and environmental security

Science.gov (United States)

Kogan, Felix

The first 13th years of the 21st century has begun with a series of widespread, long and intensive droughts around the world. Extreme and severe-to-extreme intensity droughts covered 2-6% and 7-16% of the world land, respectively, affecting environment, economies and humans. These droughts reduced agricultural production, leading to food shortages, human health deterioration, poverty, regional disturbances, population migration and death. This presentation is a travelogue of the 21st century global and regional droughts during the warmest years of the past 100 years. These droughts were identified and monitored with the NOAA operational space technology, called Vegetation Health (VH), which has the longest period of observation and provide good data quality. The VH method was used for assessment of vegetation condition or health, including drought early detection and monitoring. The VH method is based on operational satellites data estimating both land surface greenness (NDVI) and thermal conditions. The 21st century droughts in the USA, Russia, Australia Argentina, Brazil, China, India and other principal grain producing countries were intensive, long, covered large areas and caused huge losses in agricultural production, which affected food and environmental security and led to food riots in some countries. This presentation investigate how droughts affect food and environmental security, if they can be detected earlier, how to monitor their area, intensity, duration and impacts and also their dynamics during the climate warming era with satellite-based vegetation health technology.
Effect of Hurdle Technology in Food Preservation: A Review.

Science.gov (United States)

Singh, Shiv; Shalini, Rachana

2016-01-01

Hurdle technology is used in industrialized as well as in developing countries for the gentle but effective preservation of foods. Hurdle technology was developed several years ago as a new concept for the production of safe, stable, nutritious, tasty, and economical foods. Previously hurdle technology, i.e., a combination of preservation methods, was used empirically without much knowledge of the governing principles. The intelligent application of hurdle technology has become more prevalent now, because the principles of major preservative factors for foods (e.g., temperature, pH, aw, Eh, competitive flora), and their interactions, became better known. Recently, the influence of food preservation methods on the physiology and behavior of microorganisms in foods, i.e. their homeostasis, metabolic exhaustion, stress reactions, are taken into account, and the novel concept of multi-target food preservation emerged. The present contribution reviews the concept of the potential hurdles for foods, the hurdle effect, and the hurdle technology for the prospects of the future goal of a multi-target preservation of foods.

Higher socioeconomic status impacts profoundly on quality of life. Life-event stressors, such as loss of employment, marital separation/divorce, death of a spouse and food insecurity, have been found to accelerate disease progression among people with human immunodeficiency virus (HIV). The objective of this study was to determine significant independent sociodemographic and food security factors associated with HIV status in people from rural and urban communities in the Assuring Health for All study, which was undertaken in rural Trompsburg, Philippolis and Springfontein and urban Mangaung, in the Free State Province of South Africa. Sociodemographic and food security factors associated with HIV status were determined in 886 households. Logistic regression with forward selection (p rural participants, 97 (17.1%) were HIV-infected, and 172 (40.6%) of the 424 urban participants. A relatively high percentage of respondents had never attended school, while very few participants in all areas had a tertiary education. The unemployment rate of HIV-infected adults was higher than that of HIV-uninfected adults. A high percentage of respondents in all areas reported running out of money to buy food, with this tendency occurring significantly more among urban HIV-infected than HIV-uninfected respondents. In all areas, a high percentage of HIV-infected respondents relied on a limited number of foods to feed their children, with significantly more HIV-infected urban respondents compared to their uninfected counterparts reporting this. Most participants in all areas had to cut the size of meals, or ate less because there was not enough food in the house or not enough money to buy food. During periods of food shortage, more than 50% of respondents in all areas asked family, relatives or neighbours for assistance with money and/or food, which occurred at a higher percentage of HIV-infected rural participants compared to HIV-uninfected rural participants.

In today's society, snacking contributes close to one-third of daily energy intake, with many snacks consisting of energy-dense and nutrient-poor foods. Choices made with regard to snacking are affected by a multitude of factors on individual, social, and environmental levels. Social norms, for example, that emphasize healthful eating are likely to increase the intake of nutrient-rich snacks. In addition, satiety, the feeling of fullness that persists after eating, is an important factor in suppressing overconsumption, which can lead to overweight and obesity. Thus, eating snacks between meals has the potential to promote satiety and suppress overconsumption at the subsequent meal. Numerous studies have explored the relation between snack foods and satiety. These studies concluded that whole foods high in protein, fiber, and whole grains (e.g., nuts, yogurt, prunes, and popcorn) enhance satiety when consumed as snacks. Other foods that are processed to include protein, fiber, or complex carbohydrates might also facilitate satiety when consumed as snacks. However, studies that examined the effects of snack foods on obesity did not always account for satiety and the dietary quality and portion size of the snacks consumed. Thus, the evidence concerning the effects of snack foods on obesity has been mixed, with a number of interventional and observational studies not finding a link between snack foods and increased weight status. Although further prospective studies are warranted to conclusively determine the effects of snack foods on obesity risk, the consumption of healthful snacks likely affects satiety and promotes appetite control, which could reduce obesity. © 2016 American Society for Nutrition.
Identifying Areas of Primary Care Shortage in Urban Ohio

Directory of Open Access Journals (Sweden)

Hsin-Chung Liao

Full Text Available ABSTRACT: This study considers both spatial and a-spatial variables in examining accessibility to primary healthcare in the three largest urban areas of Ohio (Cleveland, Columbus, and Cincinnati. Spatial access emphasizes the importance of geographic barriers between individuals and primary care physicians, while a-spatial variables include non-geographic barriers or facilitators such as age, sex, race, income, social class, education, living conditions and language skills. Population and socioeconomic data were obtained from the 2000 Census, and primary care physician data for 2008 was provided by the Ohio Medical Board. We first implemented a two-step method based on a floating catchment area using Geographic Information Systems to measure spatial accessibility in terms of 30-minute travel times. We then used principal component analysis to group various socio-demographic variables into three groups: (1 socioeconomic disadvantages, (2 living conditions, and (3 healthcare needs. Finally, spatial and a-spatial variables were integrated to identify areas with poor access to primary care in Cleveland, Columbus, and Cincinnati. KEYWORDS: Geographic information systems, healthcare access, spatial accessibility, primary care shortage areas
Mechanisms of plastein formation, and prospective food and nutraceutical applications of the peptide aggregates

Directory of Open Access Journals (Sweden)

Min Gong

2015-03-01

Full Text Available Plastein is a protease-induced peptide aggregate with prospective application in enhancing the nutritional quality of proteins and debittering protein hydrolysates. These properties are yet to be applied in product development possibly due to economic considerations (production cost vs. product yields. This paper reviews currently proposed mechanisms of plastein formation including condensation, transpeptidation and physical interaction of aggregating peptides. Emerging findings indicate that plastein possesses bioactivities, thereby expanding its prospective application. The role of proteases in inducing peptide interaction in plastein remains unclear. Understanding the protease function will facilitate the development of efficient proteases and scalable industrial processes for plastein production.

The aim of this systematic review and meta-analysis was to summarize the evidence on the relation of the intakes of 12 major food groups, including whole grains, refined grains, vegetables, fruits, nuts, legumes, eggs, dairy, fish, red meat, processed meat, and sugar-sweetened beverages (SSBs) with the risk of hypertension. PubMed, Scopus, and Web of Science were searched systematically until June 2017 for prospective studies having quantitatively investigated the above-mentioned foods. We conducted meta-analysis on the highest compared with the lowest intake categories and linear and nonlinear dose-response meta-analyses to analyze the association. Summary RRs and 95% CIs were estimated by using a random-effects model. Overall, 28 reports were included in the meta-analysis. An inverse association for the risk of hypertension was observed for 30 g whole grains/d (RR: 0.92; 95% CI: 0.87, 0.98), 100 g fruits/d (RR: 0.97; 95% CI: 0.96, 0.99), 28 g nuts/d (RR: 0.70; 95% CI: 0.45, 1.08), and 200 g dairy/d (RR: 0.95; 95% CI: 0.94, 0.97), whereas a positive association for 100 g red meat/d (RR: 1.14; 95% CI: 1.02, 1.28), 50 g processed meat/d (RR: 1.12; 95% CI: 1.00, 1.26), and 250 mL SSB/d (RR: 1.07; 95% CI: 1.04, 1.10) was seen in the linear dose-response meta-analysis. Indication for nonlinear relations of the intakes of whole grains, fruits, fish, and processed meats with the risk of hypertension was detected. In summary, this comprehensive dose-response meta-analysis of 28 reports identified optimal intakes of whole grains, fruits, nuts, legumes, dairy, red and processed meats, and SSBs related to the risk of hypertension. These findings need to be seen under the light of very-low to low quality of meta-evidence. However, the findings support the current dietary guidelines in the prevention of hypertension. © 2017 American Society for Nutrition.

According to demographic changes, the size of the aging population has rapidly increased. Thailand has been facing the "aging society" since 2005 and the "aged society" has been projected to appear by the year 2025. Increased life expectancy is associated with health problems and risks, specifically chronic diseases and disability. Aging and aged societies and related specific conditions as stroke require the provision of services from health professionals. The shortage of the physical therapy workforce in Thailand has been reported. This study investigated the size of physical therapy workforce required for the approaching aging society of Thailand and estimated the number of needed physical therapists, specifically regarding stroke condition. Evidently, the issue of the physical therapy workforce to serve aging and aged societies in Thailand requires advocating and careful arranging.

In August 2012, a literature search with the aim of describing indicators on food and water security in an Arctic health context was initialized in collaboration between the Arctic Human Health Expert Group, SDWG/AHHEG and the AMAP (Arctic Monitoring and Assessment Programme within the Arctic Council) Human Health Assessment Group, AMAP/HHAG. In December 2012, workshop discussions were performed with representatives from both of these organizations, including 7 Arctic countries. The aim of this article is to describe the workshop discussions and the rational for the 12 indicators selected and the 9 rejected and to discuss the potential feasibility of these. Advantages and disadvantages of candidate indicators were listed. Informative value and costs for collecting were estimated separately on a 3-level scale: low, medium and high. Based on these reviews, the final selection of promoted and rejected indicators was performed and summarized in tables. Among 10 suggested indicators of food security, 6 were promoted: healthy weight, traditional food proportion in diet, monetary food costs, non-monetary food accessibility, food-borne diseases and food-related contaminants. Four were rejected: per-person dietary energy supply, food security modules, self-estimated food safety and healthy eating. Among 10 suggested indicators of water security, 6 were promoted: per-capita renewable water, accessibility of running water, waterborne diseases, drinking-water-related contaminants, authorized water quality assurance and water safety plans. Four were rejected: water consumption, types of water sources, periodic water shortages and household water costs.
Using Personal Water Footprints to Identify Consumer Food Choices that Influence the Conservation of Local Water Resources

Marrin, D. L.

2015-12-01

As the global demand for water and food escalates, the emphasis is on supply side factors rather than demand side factors such as consumers, whose personal water footprints are dominated (>90%) by food. Personal footprints include the water embedded in foods that are produced locally as well as those imported, raising the question of whether local shifts in people's food choices and habits could assist in addressing local water shortages. The current situation in California is interesting in that drought has affected an agriculturally productive region where a substantial portion of its food products are consumed by the state's large population. Unlike most agricultural regions where green water is the primary source of water for crops, California's arid climate demands an enormous volume of blue water as irrigation from its dwindling surface and ground water resources. Although California exports many of its food products, enough is consumed in-state so that residents making relatively minor shifts their food choices could save as much local blue water as their implementing more drastic reductions in household water use (comprising food group on both a caloric and gravimetric basis. Another change is wasting less food, which is a shared responsibility among consumers, producers and retailers; however, consumers' actions and preferences ultimately drive much of the waste. Personal water footprints suggest a role for individuals in conserving local water resources that is neither readily obvious nor a major focus of most conservation programs.

To evaluate the published medical literature on the prevalence and types of food allergies in South Asia. A PubMed search was performed using the keywords India and food allergy, Asia and food allergy, and South Asia and food allergy for any period. Articles cited in selected studies were reviewed for their appropriateness of inclusion into this review. Publications were included that were original research and fit the topic of food allergy and South Asia. South Asia is defined as region inclusive of India, Pakistan, Bangladesh, and Sri Lanka. A total of 169 articles were initially identified, and 47 were reviewed in detail for inclusion in this review. The primary focus was placed on 10 studies that consisted of case reports of newly reported or documented food allergy, survey studies that investigated food allergy prevalence in specific demographics, and prospective and cross-sectional studies with case controls, all of which investigated food allergy prevalence by allergy testing in a selected population. The medical literature on the prevalence and types of food allergy in South Asia indicates that there is a variety of unusual and unique allergens and an overall low incidence of food allergy. There is also an association of increased food allergy prevalence in individuals who live in metropolitan regions or who migrate to communities that have adopted westernization.

Water resources, essential to sustain human life, livelihoods and ecosystems, are under increasing pressure from population growth, socio-economic development and global climate change. As the largest freshwater resource on Earth, groundwater is key for human development and food security. Yet, excessive abstraction of groundwater for irrigation, driven by an increasing demand for food in recent decades, is leading to fast exhaustion of groundwater reserves in major agricultural areas of the world. Some of the highest depletion rates are observed in Pakistan, India, California Central Valley and the North China Plain aquifers. In addition, the growing economy and population of several countries, such as India and China, makes prospects of future available water and food worrisome. In this context, it is becoming particularly challenging to sustainably feed the world population, without exhausting our water resources. Besides, food production and consumption across the globe have become increasingly interconnected, with many areas' agricultural production destined to remote consumers. In this globalisation era, trade is crucial to the world's food system. As a transfer of water-intensive goods, across regions with varying levels of water productivity, food trade can save significant volumes of water resources globally. This situation makes it essential to address the issue of groundwater overuse for global food supply, accounting for international food trade. To do so, we quantify the current, global use of non-renewable groundwater for major crops, accounting for various water productivity and trade flows. This will highlight areas requiring quickest attention, exposing major exporters and importers of non-renewable groundwater, and thus help explore solutions to improve the sustainability of global food supply.

Kadam, Abhay B.; Maigetter, Karen; Jeffery, Roger; Mistry, Nerges F.; Weiss, Mitchell G.; Pollock, Allyson M.

2016-01-01

Background: Good drug regulation requires an effective system for monitoring and inspection of manufacturing and sales units. In India, despite widespread agreement on this principle, ongoing shortages of drug inspectors have been identified by national committees since 1975. The growth of India’s pharmaceutical industry and its large export market makes the problem more acute. Methods: The focus of this study is a case study of Maharashtra, which has 29% of India’s manufacturing units and 38% of its medicines exports. India’s regulations were reviewed, comparing international, national and state inspection norms with the actual number of inspectors and inspections. Twenty-six key informant interviews were conducted to ascertain the causes of the shortfall. Results: In 2009-2010, 55% of the sanctioned posts of drug inspectors in Maharashtra were vacant. This resulted in a shortfall of 83%, based on the Mashelkar Committee’s recommendations. Less than a quarter of the required inspections of manufacturing and sales units were undertaken. The Indian Drugs and Cosmetics Act and its Rules and Regulations make no provisions for drug inspectors and workforce planning norms, despite the growth and increasing complexity of India’s pharmaceutical industry. Conclusion: The Maharashtra Food and Drug Administration (FDA) falls short of the Mashelkar Committee’s recommended workforce planning norms. Legislation and political and operational support are required to produce needed changes PMID:27694680

Katayama, Naomi; Yoshimura, Tuyoshi; Baba, Keiichi; Space Agriculture Task Force, J.

Providing foods to space crew is the important requirements to support long term manned space exploration. We designed joyful and healthy recipe with materials (plants, insects, fish and et.cet.), which can be produced by the bio-regenerative agricultural system operated at limited resources available in spaceship or on Moon and Mars. The fundamental composition of our recipe is unpolished rice, barley, soybean, sweat potato and green-yellow vegetables. Supplement food materials to fulfill the nutritional requirements we chose are loach, silkworm pupa, termite, snail, mud snail, bee, locust, cassava, quinoa and et. cet. And the space foods were made by using IH cooking heater and vacuum cooking machine. Nutritional analysis on the basic vegetable menu consisting of rice, barley, soybean, sweet potato cassava, quinoa and green reveals a shortage of vitamins D and B12, cholesterol and sodium salt. Since vitamin D deficiency results in demineralization of bone. Vitamin B12 is essential to prevent pernicious anemia.Fish contains both vitamins D and B12. The pupa of the silkworm becomes the impor-tant nourishment source as protein and lipid. The silk thread uses it as clothing and cosmetics and medical supplies. However, we can use the silk thread as food as protein after finish to use. A law of nature shakes high quality oils and fats included in termite for cooking. I use the bee as food after having used it for the pollination of the plant. Of course the honey becomes the important food, too. The snail and mud snail become the food as protein. We decided to use the menu consisting of the basic vegetarian menu plus insect and loach for further conceptual design of space agriculture. We succeeded to develop joyful and nutritious space recipe at the end. Because of less need of agricultural resources at choosing ecological members from the lower ladder of the food chain, our space recipe could be a proposal to solve the food problem on Earth.In addition, as for these

To target pediatric dermatologists directly in order to evaluate their current demographics and the most important motivating factors that influenced their career choice. Pediatric dermatology is one of the pediatric subspecialties with an inadequate supply to meet current patient needs. A survey was designed to evaluate the training pathway, employment status, participation in teaching, and clinical practice characteristics of pediatric dermatologists. The survey was administered to attendants of the 2010 Society for Pediatric Dermatology annual meeting. Any remaining board certified pediatric dermatologists who had not previously responded were queried via Survey Monkey. There was a 71% response rate. The majority chose a career in pediatric dermatology early, often prior to starting a dermatology residency. The vast majority of respondents noted mentorship as the most important influence on their decision to pursue a career in pediatric dermatology. The most common obstacles cited by respondents were financial hardship and resistance of some dermatology programs to accept applicants previously trained in pediatrics. Our survey provides evidence to support the importance of early exposure to the field and, most importantly, to committed pediatric dermatologists who can serve as mentors. This information may be helpful in approaching solutions to the workforce shortage in the field of pediatric dermatology. Copyright © 2014 Mosby, Inc. All rights reserved.
FOOD CRISIS AS FACTOR OF FUTURE VALUE OF THE AGRICULTURAL LAND

2017-08-01

Full Text Available At the present stage of human development, food is one of the most acute problems. Over the past 30-40 years, the growth rate of population in many countries of the world is ahead of the growth rate of agricultural production, which leads to acute shortage of food. This is especially true of developing countries, which accounts for the overwhelming majority of the population of the planet that is under-eating and starving. According to FAO (Food and Agriculture Organization, in the world now about half a billion people are constantly hungry and twice asleep. Insufficient consumption affects children in particular. Nearly 300 million children in Asia, Africa and Latin America are lagging behind in physical and mental development as a result of poor nutrition. Every day from hunger there are about 12 thousand people dying. According to FAO, food products around the world are produced in general enough to feed the entire population of the Earth. However, the main reason for the global food crisis is not that products are distributed among countries irrelevant to the population, although such a problem exists. Researchers believe that the food crisis is caused by the coincidence of demographic, environmental and energy problems with the effects of adverse weather conditions, as well as a colossal increase in military spending. Investigated the interconnection between the dynamics of population growth and world food production volumes with the areas of agricultural land and the possible influence of projected changes in agricultural land use on increasing the cost of agricultural land is substantiated. It was investigated that the average national land rent in Ukraine would increase by 25.5%. This in turn will lead to an increase in the value of agricultural land in Ukraine.

Aim of the study: Indigenous woody species play an important role as a complement on the diet of rural populations in Niger, especially in periods of food scarcity. However, these species are nowadays overexploited and management programmes are necessary to conserve them. In order to design a conservation programme for edible woody species, this paper presents a sociological analysis about the use of edible woody species and their products during shortage periods in Niger. Area of study: Four villages in two distinct agro-ecological regions were selected to conduct structured enquiries based on focus group discussions and surveys with key informants. Material and Methods: Perceptions of the conservation status of these species were identified; as well the factors affecting food values, perceptions, management and collection practices. Main results: Results show that B. senegalensis was a staple food in the driest areas, and M. crassifolia was used for fodder and human consumption in the most critical situations. The local communities related the drivers of species conservation status specific to the agro-ecological regions, and gender and ethnic differences were also identified. Research highlights: Understanding these factors constitutes a first step towards adaptive management strategies for the conservation of woody food species in rural communities of Niger. (Author)

In the task of alleviating the distress caused by the world-wide food shortage it is essential to preserve what has been grown and harvested in the fields. Clearly all suitable methods for preserving agricultural produce and food should be made use of. In this context treatment with ionizing radiation has proved its value as an environmentally clean, physical method of food preservation which is low in its energy requirement, but the volume of food being processed in this way is still low. The introduction of food irradiation on a global basis poses certain economic, legal, regulatory and health-related questions, the solution of which requires close international collaboration. Such collaboration between many international, intergovernmental and national organizations began over a decade ago. The need for dissemination and discussion of information gained through research and development work on this subject became apparent, and a number of inter-regional meetings were held. The last international symposium on the topic was held jointly by FAO and the IAEA in 1972 in Bombay. To review progress made since then, FAO and the IAEA, together with WHO, convened the present Symposium on 21-25 November 1977. It appeared timely to hold this Symposium for the following reasons: (1) Apart from significant scientific work reported in the literature, progress in other directions between 1972 and 1977 had also been made. For example, the number of food items authorized by governments, with or without restriction, had grown from 19 to 26, and the number of countries accepting one or more irradiated foods for human consumption had increased from 11 to 19. (2) Largely on the basis of the work of the International Project in the Field of Food Irradiation (Karlsruhe), already described at the Bombay Symposium, an international expert committee, jointly convened by FAO, the IAEA and WHO in August-September 1976, had made important statements on the philosophy of wholesomeness studies

To assess the association between food combination and Alzheimer disease (AD) risk. Because foods are not consumed in isolation, dietary pattern (DP) analysis of food combination, taking into account the interactions among food components, may offer methodological advantages. Prospective cohort study. Northern Manhattan, New York, New York. Two thousand one hundred forty-eight community-based elderly subjects (aged > or = 65 years) without dementia in New York provided dietary information and were prospectively evaluated with the same standardized neurological and neuropsychological measures approximately every 1.5 years. Using reduced rank regression, we calculated DPs based on their ability to explain variation in 7 potentially AD-related nutrients: saturated fatty acids, monounsaturated fatty acids, omega-3 polyunsaturated fatty acids, omega-6 polyunsaturated fatty acids, vitamin E, vitamin B(12), and folate. The associations of reduced rank regression-derived DPs with AD risk were then examined using a Cox proportional hazards model. Main Outcome Measure Incident AD risk. Two hundred fifty-three subjects developed AD during a follow-up of 3.9 years. We identified a DP strongly associated with lower AD risk: compared with subjects in the lowest tertile of adherence to this pattern, the AD hazard ratio (95% confidence interval) for subjects in the highest DP tertile was 0.62 (0.43-0.89) after multivariable adjustment (P for trend = .01). This DP was characterized by higher intakes of salad dressing, nuts, fish, tomatoes, poultry, cruciferous vegetables, fruits, and dark and green leafy vegetables and a lower intake of high-fat dairy products, red meat, organ meat, and butter. Simultaneous consideration of previous knowledge regarding potentially AD-related nutrients and multiple food groups can aid in identifying food combinations that are associated with AD risk.
Meeting the Challenge of Instructor Shortages: A Blended Teaching and Learning Model for a Neuroscience Course in a Doctor of Physical Therapy Program.

Physical therapy workforce shortages are expected to increase for all 50 states through 2030. There is a recognized nationwide unprecedented shortage of well-prepared physical therapy instructors. One practical solution can be to share instructors among Doctor of Physical Therapy (DPT) programs using a blended teaching and learning model. The purpose of this project was to evaluate the effectiveness of a blended teaching and learning model for a neuroscience course in a DPT program. Faculty members from two DPT programs collaborated to develop, implement, and evaluate a blended teaching and learning model. The Blackboard Learning Management System (LMS) was available at both institutions and chosen as the learning platform. The design of this research study was retrospective nonexperimental observational. The overall feedback from the students was positive. Most students (91.6%) strongly agreed or agreed that the content of the course was appropriate for learning neuroscience. The students taking this blended course performed slightly better than the students taking the traditional course, though there was no significant difference (p=0.06). The results support the use of a blended teaching and learning model to meet faculty shortage challenges. Future research with a larger sample size is necessary.
Energy efficient cooking systems, food-preparation facilities, and human diets

The opportunities for saving energy, which are available to those working within the final link of the UK food system, i.e. at, or in relation to, the points of consumption are identified. Substantial prospective savings exist, because relatively little attention has, as yet, been given to energy-thrift in food-preparation facilities. Within the food-service industry, cooking systems are characterised by high thermal capacities, excessive external surface temperatures and poorly-designed control systems. Catering staff, who use such appliances, are rarely trained to use energy wisely when preparing foods, and kitchens tend to be designed without sufficient regard to energy-thrift. Similar problems prevail in domestic kitchens. However, manufacturers still provide household appliances, which are unnecessarily energy-profligate. (author).

The prospect of radiation application in industry and agriculture are described. In industry, the radiation-induced crosslinking of polymers and radiation-induced graft polymerization improved many chemical and physical properties and new functional materials were created using ion beams. In agriculture, the food irradiation improved the food hygiene and killed insect pest of fruits and vegetables. Furthermore, the sterile insect technique, mutation breeding of plants, positron imaging system for plant, sterilization of medical products, environmental conservation due to purification of flue gas and wastewater, and upgrading of natural polymer (polysaccharide etc.) have been performed. Radiation process is a clean one without use of chemical reagents. The electron beam radiation is expected to reduce the cost of radiation process compared with the gamma-ray radiation. (M.H.)

Gender-related Differences in Food Craving and Obesity.

Hallam, Jessica; Boswell, Rebecca G; DeVito, Elise E; Kober, Hedy

2016-06-01

Food craving is often defined as a strong desire to eat. Much work has shown that it consistently and prospectively predicts eating and weight-related outcomes, contributing to the growing obesity epidemic. Although there are clear gender differences in the prevalence and health consequences of obesity, relatively little recent work has investigated gender differences in craving, or any sex-hormone-based differences as they relate to phases of the menstrual cycle. Here, we propose that gender-related differences in food craving contribute to gender-related differences in obesity. Drawing on findings in the addiction literature, we highlight ways to incorporate gender-based differences in food craving into treatment approaches, potentially improving the efficacy of obesity and weight loss treatment. Overall, this review aims to emphasize the importance of investigating gender differences in food craving, with a view towards informing the development of more effective treatments for obesity and weight loss.

Full Text Available Food Deficiency in the Sangha Region - Congo. The problem of food shortage in Sangha region is accompanied by alarming paradoxes. The region offers extremely favorable conditions for the development of agriculture : equatorial climate with abundance of rains and sun, a lot of uncultivated areas, a lot rivers, etc. Despite these advantages, food crops production is insignificant in the light of the very high infant mortality in the area 17.5 % (6, a death rate which is often bound with malnutrition. Contrary to what is commonly admitted, this food shortage is caused neither by natural obstacles nor by a certain passivity or immobility among peasants but by bad agricultural politic in the region. This article investigates these paradoxes and suggests in the same way a frame of analyses and orientations which could help overcome the regions savers food shortage.

Full Text Available In August 2012, a literature search with the aim of describing indicators on food and water security in an Arctic health context was initialized in collaboration between the Arctic Human Health Expert Group, SDWG/AHHEG and the AMAP (Arctic Monitoring and Assessment Programme within the Arctic Council Human Health Assessment Group, AMAP/HHAG. In December 2012, workshop discussions were performed with representatives from both of these organizations, including 7 Arctic countries. The aim of this article is to describe the workshop discussions and the rational for the 12 indicators selected and the 9 rejected and to discuss the potential feasibility of these. Advantages and disadvantages of candidate indicators were listed. Informative value and costs for collecting were estimated separately on a 3-level scale: low, medium and high. Based on these reviews, the final selection of promoted and rejected indicators was performed and summarized in tables. Among 10 suggested indicators of food security, 6 were promoted: healthy weight, traditional food proportion in diet, monetary food costs, non-monetary food accessibility, food-borne diseases and food-related contaminants. Four were rejected: per-person dietary energy supply, food security modules, self-estimated food safety and healthy eating. Among 10 suggested indicators of water security, 6 were promoted: per-capita renewable water, accessibility of running water, waterborne diseases, drinking-water-related contaminants, authorized water quality assurance and water safety plans. Four were rejected: water consumption, types of water sources, periodic water shortages and household water costs.

The well-documented shortage of nurses and the impact of educational preparation of nurses on patient care outcomes provide a compelling argument for the need to increase the number of registered nurses and to advance their educational preparation. This article describes the application of human capital theory in a creative venture between a health system and a school of nursing that has demonstrated success in addressing these issues. A tuition advancement program was developed to support interested personnel in attaining the associate degree in nursing and to support current RNs in attaining the baccalaureate degree. The venture included support for graduate preparation of nurses interested in becoming faculty.

To find out how the consumption of organic food during pregnancy is associated with consumer characteristics, dietary patterns and macro- and micronutrient intakes. Cross-sectional description of consumer characteristics, dietary patterns and macro- and micronutrient intakes associated with consumption of organic food during pregnancy. Healthy, pregnant women recruited to a prospective cohort study at midwives' practices in the southern part of the Netherlands; to enrich the study with participants adhering to alternative lifestyles, pregnant women were recruited through various specific channels. Participants who filled in questionnaires on food frequency in gestational week 34 (n 2786). Participant groups were defined based on the share of organic products within various food types. Consumers of organic food more often adhere to specific lifestyle rules, such as vegetarianism or anthroposophy, than do participants who consume conventional food only (reference group). Consumption of organic food is associated with food patterns comprising more products of vegetable origin (soya/vegetarian products, vegetables, cereal products, bread, fruits, and legumes) and fewer animal products (milk and meat), sugar and potatoes than consumed in conventional diets. These differences translate into distinct intakes of macro- and micronutrients, including higher retinol, carotene, tocopherol and folate intakes, lower intakes of vitamin D and B12 and specific types of trans-fatty acids in the organic groups. These differences are seen even in groups with low consumption of organic food. Various consumer characteristics, specific dietary patterns and types of food intake are associated with the consumption of organic food during pregnancy.
Plant foods and plant-based diets: protective against childhood obesity?

Science.gov (United States)

Newby, P K

2009-05-01

The objective of this article is to review the epidemiologic literature examining the role of plant foods and plant-based diets in the prevention of childhood obesity. Available data suggest a protective effect of ready-to-eat cereal on risk of obesity, although prospective studies are still needed. Studies on fruit and vegetables; grains other than cereal; high-protein foods, including beans, legumes, and soy; fiber; and plant-based dietary patterns are inconsistent or generally null. The evidence base is limited, and most studies are fraught with methodologic limitations, including cross-sectional design, inadequate adjustment for potential confounders, and lack of consideration of reporting errors, stage of growth, and genetic influences. Well-designed prospective studies are needed. The lack of evidence showing an association between plant-based diets and childhood obesity does not mean that such diets should not be encouraged. Plant foods are highlighted in the Dietary Guidelines for Americans, and children do not meet the current recommendations for most plant foods. Although the advice to consume a plant-based, low-energy-dense diet is sound, ethical questions arise concerning the relatively high price of these diets in the United States and the way in which such diets are perceived in other parts of the world. Reducing the burden of childhood obesity, eliminating health disparities, and preventing the further spread of the disease around the globe will require not only policy interventions to ensure that plant foods are affordable and accessible to children of all income levels but also awareness of sociocultural norms that affect consumption.
A Catalyst for Change: Drought and Food Security in the Near East Region (Invited)

Knutson, C. L.

2010-12-01

In the Near East, drought at the turn of the 21st century was reported to be the worst in 50 years, affecting millions of people across the region. The drought caused a wide range of effects, including widespread crop failures and livestock losses, increased drinking water shortages and disease stress, additional debt, and forced mass migrations to urban areas and other countries, all of which affected food security. As devastating as the drought was for people and the environment, the event created a “policy window” - a time during which the public’s and policy makers’ attention was directed toward a particular issue, creating an advantageous political environment for addressing the problem. In this case, the drought revealed the need for enhanced mitigation and drought relief coordination. It has served as the impetus for several countries and international organizations to work together to foster new policies and training activities to reduce drought risk and enhance food security in the region.

Calcium homeostasis is crucial to eukaryotic cell survival. By acting as an enzyme cofactor and a second messenger in several signal transduction pathways, the calcium ion controls many essential biological processes. Inside the endoplasmic reticulum (ER) calcium concentration is carefully regulated to safeguard the correct folding and processing of secretory proteins. By using the model organism Saccharomyces cerevisiae we show that calcium shortage leads to a slowdown of cell growth and met...

Cellulosic nanomaterials (CNMs) are organic, green nanomaterials that are obtained from renewable sources and possess exceptional mechanical strength and biocompatibility. The associated unique physical and chemical properties have made these nanomaterials an intriguing prospect for various applications including the food and nutraceutical industry. From the immobilization of various bioactive agents and enzymes, emulsion stabilization, direct food additives, to the development of intelligent packaging systems or pathogen or pH detectors, the potential food related applications for CNMs are endless. Over the past decade, there have been several reviews published covering different aspects of cellulosic nanomaterials, such as processing-structure-property relationship, physical and chemical properties, rheology, extraction, nanocomposites, etc. In this critical review, we have discussed and provided a summary of the recent developments in the utilization of cellulosic nanomaterials in applications related to food and nutraceuticals.
Food resources of the California condor

food source may become most productive and significant in the preservation of this species. These sites, which are in the Piru Creek area, are outside the boundaries o:f the Sespe Condor Sanctuary, but are recognized by the U.S. Forest Service (1971) as extremely important to condor survival. Protective measures recommended in the Forest Service plan should be implemented as soon as possible to preserve this area's usefulness as condor nesting habitat. Food may not be the factor currently limiting condor reproduction. However, the reproductive rate is inadequate to sustain the condor population for long. As food shortage has been shown to limit breeding in many species (Lack 1954, 1966), and as it is something which can be manipulated, it is a logical factor for further study and experimentation.
Successful importation of cytarabine into the United States during a critical national drug shortage.

The importation of cytarabine into the United States during a critical national drug shortage is described. In March 2011, the hospital pharmacy team at an acute care hospital was struggling to supply cytarabine for four specific patients, all of whom needed critical maintenance therapy after induction. Cytarabine was not available from any source in the United States, and the team had no realistic projected release dates for back orders. Idis UK, a pharmaceutical distributor, was asked to identify available drug and eventually found an unrestricted source of cytarabine in Switzerland. Once available drug was identified, a price quote for the supply amount was written for our consideration. This was inspected carefully to ensure that the drug, strength, dosage form, and any other ingredients listed were indeed what were expected. The pharmacy department worked with the hospital's department of finance and accounting to submit the necessary financial paperwork. Payment was electronically sent to the distributor before the drug was shipped. Before the order for cytarabine was placed, the associated risks and benefits were assessed. The patients provided consent to treatment with the unapproved product. Acceptance of the price quote and instructions to order the drug were e-mailed to the distributor. The necessary documentation was completed and included with the shipment. The importation process, from initial inquiries to delivery, took 21 days. The importation of cytarabine amid a drug shortage required a complex process that involved the efforts of an overseas distributor, the cooperation of multiple health professionals, and meticulous attention to detail.

Comparison of projected future water demand and supply across the conterminous United States indicates that, due to improving efficiency in water use, expected increases in population and economic activity do not by themselves pose a serious threat of large-scale water shortages. However, climate change can increase water demand and decrease water supply to the extent...
The world food problem

Energy Technology Data Exchange (ETDEWEB)

Olson, R A

1974-07-01

Argument continues in the world press as to the urgency of the food problem. Some economists in equating world food production statistics with population figures have convinced themselves there is more than enough food per capita and, accordingly, no problem. Looking in greater depth than these gross averages, however, we find that there is indeed a prospective problem, and of such a nature and magnitude as to tax all of mankind's talents and resources in its resolution. It is true that certain of the developed countries of the world in the last generation acquired agricultural production capabilities that notably exceeded the resident population's capacity to consume. 'Surplus' in these areas became an ugly word during this period of a generally favorable weather cycle, and restrictions on the amount of and that could be devoted to graincrops were imposed to curb this tremendous capacity. A fickle Mother Nature, however, has turned things around during the early 1970's by one or another of her many vacillations in the form of local drought, excess moisture, shortened growing season, or other means, in some of the major producing areas. Inconsequence, the food grain surpluses are now gone and the world is looking at a three to four week reserve at any given moment. The cost of food products available from exporting countries has doubled and trebled in price during the past two years. The potential for famine exceeds in magnitude anything the world has ever known. It is against this background that the World Food Conference will be held in Rome during November of this year.

Although fossil fuels do not risk being exhausted soon, the specter of scarcity is haunting the oil market. This market has fallen victim to a historical shortage of investments and a rising demand that is less elastic than expected. Moreover, higher oil prices seem to have no effect on investment decisions, nor on consumer behavior. Should we resignedly accept prices rising up to one or even two hundred dollars a barrel? And should we passively accept having poor countries pay for the thoughtlessness of wealthy lands? (author)

Background Longitudinal epidemiological studies require both the periodic update of intake information via repeated dietary survey and the minimization of subject burden in responding to questionnaires. We developed a 66-item Food Frequency Questionnaire (short-FFQ) for the Japan Public Health Center-based prospective Study for the Next Generation (JPHC-NEXT) follow-up survey using major foods from the FFQ developed for the original JPHC Study. For the JPHC-NEXT baseline survey, we used a larger 172-item FFQ (long-FFQ), which was also derived from the JPHC-FFQ. We compared the validity of ranking individuals by levels of dietary consumption by these FFQs among residents of selected JPHC-NEXT study areas. Methods From 2012 to 2013, 240 men and women aged 40–74 years from five areas in the JPHC-NEXT protocol were asked to respond to the long-FFQ and provide 12-day weighed food records (WFR) as reference; 228 also completed the short-FFQ. Spearman’s correlation coefficients (CCs) between estimates from the FFQs and WFR were calculated and corrected for intra-individual variation of the WFR. Results Median CC values for energy and 53 nutrients for the short-FFQ for men and women were 0.46 and 0.44, respectively. Respective values for the long-FFQ were 0.50 and 0.43. Compared with the long-FFQ, cross-classification into exact plus adjacent quintiles with the short-FFQ ranged from 68% to 91% in men and 58% to 85% in women. Conclusions Similar to the long-FFQ, the short-FFQ provided reasonably valid measures for ranking middle-aged and elderly Japanese for many nutrients and food groups. The short-FFQ can be used in follow-up surveys in prospective cohort studies aimed at updating diet rank information. PMID:27064130
Adaptive Governance and Market Heterogeneity: An Institutional Analysis of an Urban Food System in Sub-Saharan Africa

Full Text Available African cities face immense challenges over the coming decades. As countries urbanize, African cities must maintain service provision for rapidly increasing populations, yet with limited resources. In particular, urban food systems must be able to cope with regional food shortages and catalyze (or at least enable the distribution of food from diverse sources in order to ensure that the cost of food remains affordable for all of the segments of a city’s population. Food systems in most African cities are composed of wholesale sellers, formal markets, street vendors, shops, and increasingly large-scale international stores, creating an evolving landscape of food sources. At the same time, urban population growth can result in rapid changes in urban structure with new peri-urban development and transitions in socioeconomic status within existing areas. Governance plays an important role in the creation and coordination of formal and informal actors across different types of food providers. At the municipal level, new markets must be approved to keep pace with urban expansion. Within residential areas, market management committees must work to maintain traditional markets in the context of increasing competition from large-scale grocers and small-scale street vendors. We use household and market-level data that was collected in Lusaka, Zambia, to conduct an institutional analysis of residential areas to examine the interplay between households, public markets, and street vendors. Analysis of the city’s food system identifies a complex network of relationships featuring formal and informal governance arrangements, which may affect food system functionality.

In today’s society, snacking contributes close to one-third of daily energy intake, with many snacks consisting of energy-dense and nutrient-poor foods. Choices made with regard to snacking are affected by a multitude of factors on individual, social, and environmental levels. Social norms, for example, that emphasize healthful eating are likely to increase the intake of nutrient-rich snacks. In addition, satiety, the feeling of fullness that persists after eating, is an important factor in suppressing overconsumption, which can lead to overweight and obesity. Thus, eating snacks between meals has the potential to promote satiety and suppress overconsumption at the subsequent meal. Numerous studies have explored the relation between snack foods and satiety. These studies concluded that whole foods high in protein, fiber, and whole grains (e.g., nuts, yogurt, prunes, and popcorn) enhance satiety when consumed as snacks. Other foods that are processed to include protein, fiber, or complex carbohydrates might also facilitate satiety when consumed as snacks. However, studies that examined the effects of snack foods on obesity did not always account for satiety and the dietary quality and portion size of the snacks consumed. Thus, the evidence concerning the effects of snack foods on obesity has been mixed, with a number of interventional and observational studies not finding a link between snack foods and increased weight status. Although further prospective studies are warranted to conclusively determine the effects of snack foods on obesity risk, the consumption of healthful snacks likely affects satiety and promotes appetite control, which could reduce obesity.
