Caloric Supply Research Articles

Burn Institute of Southwest Hospital and I

Dr. Wang has engaged in surgery and burn medicine for 61 years. He is one of the first generation of burn doctor in China, who treated burn patients more than ten thousands and went to dozens of cities and areas to rescue the wounded near hundred batches. He made contribution to the establishment of Chinese special scheme for treating burn patients. He established the institute lab of metabolism and nutrition in 1985, and treated burn patients and carried out research of burn metabolism and nutrition simultaneously. He developed new theory that other routes like internal organs especially intestine besides burn wound can induce hypermetabolism i. e." enterogenous hypermetabolism" . If gut works, early feeding (EF) and enteral nutrition (EN) are better than delayed feeding and parenteral nutrition, and EN or EF can promote gastrointestinal resuscitation, reduce intestine injury, modulate hypothalamus and pituitary function, and decrease hypermetabolism. At the end of the 1980s, by measuring the resting energy expenditure of 105 adult burn patients and normal adults, they worked out the first formula for calories supply in Chinese burn adults. He published 340 papers, while 50 papers were exchanged in international meeting, and published 53 monographs (as editor or associate editor in chief for 9 books). Metabolism and Nutrition in Burns is the 1st burn metabolism and nutrition book in China. We got 24 awards of nation, army, and provincial and ministerial level in science, technology, medicine, and education, and there were two awards of " National 2nd Science and Technology Award" (respectively the 1st and 2nd author). He was the chairman of Burn Institute of Southwest Hospital during 1988-1999, and the institute was appraised as " Model Unit of Grass-roots in General Logistics Department" and awarded the 1st and the 2nd collective merits during that time. He was the vice president of Chinese Burn Association and chief editor of Chinese Journal of Burns.

Estimated global overweight and obesity burden in pregnant women based on panel data model.

ObjectiveTo estimate the global and country-level burden of overweight and obesity among pregnant women from 2005 to 2014.MethodsPublicly accessible country-level data were collected from the World Health Organization, the World Bank and the Food and Agricultural Organization. We estimated the number of overweight and obese pregnant women among 184 countries and determined the time-related trend from 2005 to 2014. Based on panel data model, we determined the effects of food energy supply, urbanization, gross national income and female employment on the number of overweight and obese pregnant women.ResultsWe estimated that 38.9 million overweight and obese pregnant women and 14.6 million obese pregnant women existed globally in 2014. In upper middle income countries and lower middle income countries, there were sharp increases in the number of overweight and obese pregnant women. In 2014, the percentage of female with overweight and obesity in India was 21.7%, and India had the largest number of overweight and obese pregnant women (4.3 million), which accounted for 11.1% in the world. In the United States of America, a third of women were obese, and the number of obese pregnant women was 1.1 million. In high income countries, caloric supply and urbanization were positively associated with the number of overweight and obese pregnant women. The percentage of employment in agriculture was inversely associated with the number of overweight and obese pregnant women, but only in upper middle income countries and lower middle income countries.ConclusionThe number of overweight and obese pregnant women has increased in high income and middle income countries. Environmental changes could lead to increased caloric supply and decreased energy expenditure among women. National and local governments should work together to create a healthy food environment.

Inicio de la nutrición en pacientes con trauma abdominal grave

Trauma is a frequent cause of consultation in Colombia and in severe cases it requires experienced management in the Emergency Department, operating room, and in the intensive care unit to achieve the best results. AimTo review the recommendations to start nutrition in patients with severe abdominal injuries. MethodologyA review of the subject was performed using a literature search of recent scientific papers using database like Medline and Scopus. Available evidence-based recommendations were synthesised according to the classification of the Evidence Based Medicine Centre. ConclusionCritical care patients have a high level of metabolic stress due to their abdominal injuries, and need to have an adequate provision of calories and proteins early on, in order to avoid irreversible loss of muscular mass and even fatal outcomes.

An improved anther culture procedure for obtaining new commercial Mediterranean temperate japonica rice (Oryza sativa) genotypes.

Rice is one of the greatest calorie supply for the world population, especially since its production is almost entirely destined to direct human consumption and its demand will increase along with the world population. There are efforts worldwide to increase rice yields by obtaining new improved and stabilized rice lines. The rice anther culture, a fast and cheap technique, allows to obtain double haploid lines in less than one year. We report its application with an improved protocol in four Mediterranean japonica rice genotypes at F2 generation. We performed a screening test for cold-pretreatment at 5.0±0.1°C and concluded that the optimum duration was 9 days as it produced the higher rate of anther-derived callus induction. This revised protocol was successfully applied to the four genotypes, obtaining good results in all the procedure's steps. At the end, more than 100 of double haploid green plants were generated. Moreover, 9 lines obtained from the anther culture procedure showed good qualities for the Spanish market at the growing, farming and grain production level during the field assays. Therefore, we report an improved anther culture procedure for obtaining double haploid lines from temperate japonica rice genotypes showing high commercialization expectance.

Don't Count Calorie Labeling Out: Calorie Counts on the Left Side of Menu Items Lead to Lower Calorie Food Choices

Providing calorie counts on restaurants’ menus/menu boards is one of the most prominent policy interventions that has been implemented to combat the obesity epidemic in America. However, previous research across multiple disciplines has found little effect of providing calorie counts on calories ordered, leading some to call calorie provision a failed policy. The authors propose that this failure is partly due to not considering how people process information when making food choices: Americans read from left‐to‐right, processing calorie information only after processing the food item's name. Thus, the authors test a simple way to improve the effectiveness of calorie counts: display calorie counts to the left (vs. right) of food items. A field study and a laboratory study with American participants found that calorie counts to the left (vs. right) decreased calories ordered by 16.31%. A final laboratory study demonstrated that this effect is reversed among Hebrew‐speakers, who read from right‐to‐left, providing further evidence that the order in which calorie information is processed matters. Accordingly, calling calorie labeling a policy failure may be premature.

Abstract PD-026: ENERGY INTAKE AND OUTCOMES IN CRITICALLY ILL CHILDREN WITH BRONCHIOLITIS

Aims & Objectives: Optimal nutritional practices in the paediatric intensive care unit (PICU) are largely unknown. We aimed to investigate if appropriate calorie provision leads to shorter PICU stay and fewer invasive ventilator days in critically ill children with bronchiolitis. Methods We conducted a retrospective study on patients with bronchiolitis requiring at least 72 hours stay in the PICU from 2009 – 2014. Baseline demographics, PICU medical data and energy intake in their first seven days of stay were collected. Outcomes of interest were length of PICU stay and invasive ventilation duration. We determined energy requirements using the Schofield equation without addition of stress factors. Underfeeding was defined as the average daily energy intake to requirement ratio <0.8, and overfeeding >1.2. Clinical outcomes were compared among the three groups of patients (underfed, sufficiently-fed, overfed). Results 44 patients were included (Table 1), with median age of 4.7 months (interquartile range [IQR] 1.0 – 10.6 months). Median PICU stay was 8.0 (IQR 6.0 – 12.0) days. 39 patients (88.6%) required invasive ventilation, with median ventilation duration of 7.0 (IQR 4.0 – 9.8) days. Median energy intake to requirement ratio was 0.9 (IQR 0.76 – 1.16). 15 (34.1%) patients were underfed, while 10 (22.8%) were overfed. There was no significant difference in the PICU stay lengths nor invasive ventilation duration between groups (Table 2).Conclusions Our results suggest that energy adequacy did not significantly affect PICU stay length or ventilator dependence in critically ill children with bronchiolitis.

Carbon dioxide (CO2) levels this century will alter the protein, micronutrients, and vitamin content of rice grains with potential health consequences for the poorest rice-dependent countries.

Declines of protein and minerals essential for humans, including iron and zinc, have been reported for crops in response to rising atmospheric carbon dioxide concentration, [CO2]. For the current century, estimates of the potential human health impact of these declines range from 138 million to 1.4 billion, depending on the nutrient. However, changes in plant-based vitamin content in response to [CO2] have not been elucidated. Inclusion of vitamin information would substantially improve estimates of health risks. Among crop species, rice is the primary food source for more than 2 billion people. We used multiyear, multilocation in situ FACE (free-air CO2 enrichment) experiments for 18 genetically diverse rice lines, including Japonica, Indica, and hybrids currently grown throughout Asia. We report for the first time the integrated nutritional impact of those changes (protein, micronutrients, and vitamins) for the 10 countries that consume the most rice as part of their daily caloric supply. Whereas our results confirm the declines in protein, iron, and zinc, we also find consistent declines in vitamins B1, B2, B5, and B9 and, conversely, an increase in vitamin E. A strong correlation between the impacts of elevated [CO2] on vitamin content based on the molecular fraction of nitrogen within the vitamin was observed. Finally, potential health risks associated with anticipated CO2-induced deficits of protein, minerals, and vitamins in rice were correlated to the lowest overall gross domestic product per capita for the highest rice-consuming countries, suggesting potential consequences for a global population of approximately 600 million.

Calorie intake and short-term survival of critically ill patients

The association between calorie supply and outcome of critically ill patients is unclear. Results from observational studies contradict findings of randomized studies, and have been questioned because of unrecognized confounding by indication. The present study wanted to re-examine the associations between the daily amount of calorie intake and short-term survival of critically ill patients using several novel statistical approaches. 9661 critically ill patients from 451 ICUs were extracted from an international database. We examined associations between survival time and three pragmatic nutritional categories (I: <30% of target, II: 30-70%, III: >70%) reflecting different amounts of total daily calorie intake. We compared hazard ratios for the 30-day risk of dying estimated for different hypothetical nutrition support plans (different categories of daily calorie intake during the first 11 days after ICU admission). To minimize indication bias, we used a lag time between nutrition and outcome, we particularly considered daily amounts of calorie intake, and we adjusted results to the route of calorie supply (enteral, parenteral, oral). 1974 patients (20.4%) died in hospital before day 30. Median of daily artificial calorie intake was 1.0kcal/kg [IQR 0.0-4.1] in category I, 12.3kcal/kg [9.4-15.4] in category II, and 23.5kcal/kg [19.5-27.8] in category III. When compared to a plan providing daily minimal amounts of calories (category I), the adjusted minimal hazard ratios for a delayed (from day 5-11) or an early (from day 1-11) mildly hypocaloric nutrition (category II) were 0.71 (95% confidence interval [CI], 0.54 to 0.94) and 0.56 (95% CI, 0.38 to 0.82), respectively. No substantial hazard change could be detected, when a delayed or an early, near target calorie intake (category III) was compared to an early, mildly hypocaloric nutrition. Compared to a severely hypocaloric nutrition, a mildly hypocaloric nutrition is associated with a decreased risk of death. In unselected critically ill patients, this risk cannot be reduced further by providing amounts of calories close to the calculated target. ID number ISRCTN17829198, website http://www.isrctn.org.

Nutrition in the ICU: new trends versus old-fashioned standard enteral feeding?

The narrative review aims to summarize the relevant studies from the last 2 years and provide contextual information to understand findings. Recent ICU studies have provided insight in the pathophysiology and time course of catabolism, anabolic resistance, and metabolic and endocrine derangements interacting with the provision of calories and proteins.Early provision of high protein intake and caloric overfeeding may confer harm. Refeeding syndrome warrants caloric restriction and to identify patients at risk phosphate monitoring is mandatory.Infectious complications of parenteral nutrition are associated with overfeeding. In recent studies enteral nutrition is no longer superior over parenteral nutrition.Previously reported benefits of glutamine, selenium, and fish oil seem to have vanished in recent studies; however, studies on vitamin C, thiamine, and corticosteroid combinations show promising results. Studies from the last 2 years will have marked impact on future nutritional support strategies and practice guidelines for critical care nutrition as they challenge several old-fashioned concepts.

Impacts and Uncertainties of +2°C of Climate Change and Soil Degradation on European Crop Calorie Supply.

Even if global warming is kept below +2°C, European agriculture will be significantly impacted. Soil degradation may amplify these impacts substantially and thus hamper crop production further. We quantify biophysical consequences and bracket uncertainty of +2°C warming on calories supply from 10 major crops and vulnerability to soil degradation in Europe using crop modeling. The Environmental Policy Integrated Climate (EPIC) model together with regional climate projections from the European branch of the Coordinated Regional Downscaling Experiment (EURO‐CORDEX) was used for this purpose. A robustly positive calorie yield change was estimated for the EU Member States except for some regions in Southern and South‐Eastern Europe. The mean impacts range from +30 Gcal ha−1 in the north, through +25 and +20 Gcal ha−1 in Western and Eastern Europe, respectively, to +10 Gcal ha−1 in the south if soil degradation and heat impacts are not accounted for. Elevated CO2 and increased temperature are the dominant drivers of the simulated yield changes in high‐input agricultural systems. The growth stimulus due to elevated CO2 may offset potentially negative yield impacts of temperature increase by +2°C in most of Europe. Soil degradation causes a calorie vulnerability ranging from 0 to 50 Gcal ha−1 due to insufficient compensation for nutrient depletion and this might undermine climate benefits in many regions, if not prevented by adaptation measures, especially in Eastern and North‐Eastern Europe. Uncertainties due to future potentials for crop intensification are about 2–50 times higher than climate change impacts.

Plantain flour: A potential nutraceutical ingredient to increase fiber and reduce starch digestibility of gluten‐free cookies

There is interest in the production of gluten‐free foods with high dietary fibre content and low caloric supply. It is well known that gluten‐free foods present a poor matrix due to the absence of gluten, a protein that builds the network which provides the accepted textural characteristics of bakery products and pasta. Moreover, gluten‐free products have a low dietary fibre content due to the use of starch or refined flours. The aim of this study was to evaluate the use of unripe plantain flour (UPF) to prepare gluten‐free cookies with high dietary fibre content. A commercial high dietary fibre ingredient (Hi‐Maize 260®) was used for comparison. The hardness, chemical composition, and starch digestibility of the cookies were assessed. The texture and the proximal composition of both cookies was similar, but the dietary fibre content of the cookie with UPF was 100% higher than that of Hi‐Maize 260®, and the former showed a lower predicted glycaemic index. These results indicated that unripe plantain flour can be used as a substitute for commercial ingredients to produce gluten‐free cookies with high dietary fibre content and a low predicted glycaemic index.

Parenteral Nutrition-Associated Liver Disease: The Role of the Gut Microbiota.

Parenteral nutrition (PN) provides life-saving nutritional support in situations where caloric supply via the enteral route cannot cover the necessary needs of the organism. However, it does have serious adverse effects, including parenteral nutrition-associated liver disease (PNALD). The development of liver injury associated with PN is multifactorial, including non-specific intestine inflammation, compromised intestinal permeability, and barrier function associated with increased bacterial translocation, primary and secondary cholangitis, cholelithiasis, short bowel syndrome, disturbance of hepatobiliary circulation, lack of enteral nutrition, shortage of some nutrients (proteins, essential fatty acids, choline, glycine, taurine, carnitine, etc.), and toxicity of components within the nutrition mixture itself (glucose, phytosterols, manganese, aluminium, etc.). Recently, an increasing number of studies have provided evidence that some of these factors are directly or indirectly associated with microbial dysbiosis in the intestine. In this review, we focus on PN-induced changes in the taxonomic and functional composition of the microbiome. We also discuss immune cell and microbial crosstalk during parenteral nutrition, and the implications for the onset and progression of PNALD. Finally, we provide an overview of recent advances in the therapeutic utilisation of pro- and prebiotics for the mitigation of PN-associated liver complications.

Caloric restriction extends yeast chronological lifespan via a mechanism linking cellular aging to cell cycle regulation, maintenance of a quiescent state, entry into a non-quiescent state and survival in the non-quiescent state.

A yeast culture grown in a nutrient-rich medium initially containing 2% glucose is not limited in calorie supply. When yeast cells cultured in this medium consume glucose, they undergo cell cycle arrest at a checkpoint in late G1 and differentiate into quiescent and non-quiescent cell populations. Studies of such differentiation have provided insights into mechanisms of yeast chronological aging under conditions of excessive calorie intake. Caloric restriction is an aging-delaying dietary intervention. Here, we assessed how caloric restriction influences the differentiation of chronologically aging yeast cultures into quiescent and non-quiescent cells, and how it affects their properties. We found that caloric restriction extends yeast chronological lifespan via a mechanism linking cellular aging to cell cycle regulation, maintenance of quiescence, entry into a non-quiescent state and survival in this state. Our findings suggest that caloric restriction delays yeast chronological aging by causing specific changes in the following: 1) a checkpoint in G1 for cell cycle arrest and entry into a quiescent state; 2) a growth phase in which high-density quiescent cells are committed to become low-density quiescent cells; 3) the differentiation of low-density quiescent cells into low-density non-quiescent cells; and 4) the conversion of high-density quiescent cells into high-density non-quiescent cells.

Hunger and microbiology: is a low gastric acid-induced bacterial overgrowth in the small intestine a contributor to malnutrition in developing countries?

SummaryUnderproduction of hydrochloric acid into the stomach is frequently encountered in subjects from developing countries. We explore the hypothesis that hypochlorhydria compromises the gastric barrier and favours bacterial overgrowth in the proximal parts of the small intestine where nutrient absorption takes place. Food calories are thus deviated into bacterial metabolism. In addition to an adequate caloric supply, correcting hypochlorhydria might be needed to decrease childhood malnutrition.

A cross-scale impact assessment of European nature protection policies under contrasting future socio-economic pathways

Protection of natural or semi-natural ecosystems is an important part of societal strategies for maintaining biodiversity, ecosystem services, and achieving overall sustainable development. The assessment of multiple emerging land use trade-offs is complicated by the fact that land use changes occur and have consequences at local, regional, and even global scale. Outcomes also depend on the underlying socio-economic trends. We apply a coupled, multi-scale modelling system to assess an increase in nature protection areas as a key policy option in the European Union (EU). The main goal of the analysis is to understand the interactions between policy-induced land use changes across different scales and sectors under two contrasting future socio-economic pathways. We demonstrate how complementary insights into land system change can be gained by coupling land use models for agriculture, forestry, and urban areas for Europe, in connection with other world regions. The simulated policy case of nature protection shows how the allocation of a certain share of total available land to newly protected areas, with specific management restrictions imposed, may have a range of impacts on different land-based sectors until the year 2040. Agricultural land in Europe is slightly reduced, which is partly compensated for by higher management intensity. As a consequence of higher costs, total calorie supply per capita is reduced within the EU. While wood harvest is projected to decrease, carbon sequestration rates increase in European forests. At the same time, imports of industrial roundwood from other world regions are expected to increase. Some of the aggregate effects of nature protection have very different implications at the local to regional scale in different parts of Europe. Due to nature protection measures, agricultural production is shifted from more productive land in Europe to on average less productive land in other parts of the world. This increases, at the global level, the allocation of land resources for agriculture, leading to a decrease in tropical forest areas, reduced carbon stocks, and higher greenhouse gas emissions outside of Europe. The integrated modelling framework provides a method to assess the land use effects of a single policy option while accounting for the trade-offs between locations, and between regional, European, and global scales.

Nutritional risk in allogeneic stem cell transplantation: rationale for a tailored nutritional pathway.

Hematopoietic stem cell transplantation carries nutrition-related risks. Therefore, nutritional therapy needs to be initiated before transplantation even takes place. We assessed nutritional risk among patients who underwent allogeneic stem cell transplantation. We assessed nutrient supply (calorie supply and protein supply) by chart review. Assessments were made from the pretreatment phase of transplantation to after the end of parenteral nutrition in 51 patients who underwent allogeneic stem cell transplantation at Shizuoka Cancer Center between 2007 and 2012. We compared nutrition-related adverse events and parameters between two groups: those in whom % loss of body weight was ≥7.5 and those in whom % loss of body weight was <7.5. A correlation was observed between changes in weight and skeletal muscle mass (r=0.89; P<0.0001). A weak correlation was observed between % loss of body weight and nutrient supply of calories (r=0.517; P=0.0001). There were significant differences between the % loss of body weight ≥7.5 group and the % loss of body weight <7.5 group in the following variables: % loss of body weight, nutrient supply from calories and protein; orally ingested nutrient supply from calories and protein; start day of oral intake; and acute graft-versus-host disease. Orally ingested calories were negatively correlated with nutrition-related adverse events in both groups. Early and customized nutritional intervention may be optimal for all patients who undergo allogeneic stem cell transplantation to ameliorate body weight loss associated with nutrition-related adverse events.

Implementation of enteral feeding protocol in an intensive care unit: Before-and-after study.

AIMTo determine the effects of implementing an enteral feeding protocol on the nutritional delivery and outcomes of intensive care patients.METHODSAn uncontrolled, observational before-and-after study was performed in a tertiary mixed medical-surgical intensive care unit (ICU). In 2013, a nurse-driven enteral feeding protocol was developed and implemented in the ICU. Nutrition and outcome-related data from patients who were treated in the study unit from 2011-2012 (the Before group) and 2014-2015 (the After group) were obtained from a local electronic database, the national Population Registry and the hospital’s Infection Control Service. Data from adult patients, readmissions excluded, who were treated for at least 7 d in the study unit were analysed.RESULTSIn total, 231 patients were enrolled in the Before and 249 in the After group. The groups were comparable regarding demographics, patient profile, and severity of illness. Fewer patients were mechanically ventilated on admission in the After group (86.7% vs 93.1% in the Before group, P = 0.021). The prevalence of hospital-acquired infections, length of ICU stay and ICU, 30- and 60-d mortality did not differ between the groups. Patients in the After group had a lower 90-d (P = 0.026) and 120-d (P = 0.033) mortality. In the After group, enteral nutrition was prescribed less frequently (P = 0.039) on day 1 but significantly more frequently on all days from day 3. Implementation of the feeding protocol resulted in a higher cumulative amount of enterally (P = 0.049) and a lower cumulative amount of parenterally (P < 0.001) provided calories by day 7, with an overall reduction in caloric provision (P < 0.001). The prevalence of gastrointestinal symptoms was comparable in both groups, as was the frequency of prokinetic use. Underfeeding (total calories < 80% of caloric needs, independent of route) was observed in 59.4% of the study days Before vs 76.9% After (P < 0.001). Inclusion in the Before group, previous abdominal surgery, intra-abdominal hypertension and the sum of gastrointestinal symptoms were found to be independent predictors of insufficient enteral nutrition.CONCLUSIONThe use of a nurse-driven feeding protocol improves the delivery of enteral nutrition in ICU patients without concomitant increases in gastrointestinal symptoms or intra-abdominal hypertension.

Escaping from Hunger Before Ww1: Nutrition and Living Standards in Western Europe and USA in the Late Nineteenth Century

We estimate calories available to workers' households in the USA, Belgium, Britain, France and Germany in 1890/1. We employ data from the United States Commissioner of Labor survey (see Haines, 1979) of workers in key export industries. We estimate that households in the USA, on average, had about five hundred daily calories per equivalent adult more than their French and German counterparts, with Belgian and British workers closer to the USA levels. We ask if that energy bonus gave the US workers more energy for work, and we conclude that, if stature is taken into account, workers in the US and UK probably had roughly the same level energy available for work, whereas the German and French workers most likely had significantly less. Finally we ask economic migration leads to taller children. To answer that we estimate the influence of children on calorie availability among ethnically British workers in the USA and, separately, among British workers in Britain. We find that US-based British households are at least as generous in terms of the provision of calories to their children as their Britain-based counterparts. Other things equal, this means that US-based British children would grow taller.

Projections of food demand and supply in Bangladesh: implications on food security and water demand

The objectives of this study was to project demand for and supply of key food commodities in Bangladesh by 2030 and 2050 and assess their demand-supply gap. The scope of the forecast was confined with selected 11 food items and used almost ideal demand system (AIDS) and auto regressive integrated moving average (ARIMA) models. Projections showed that food consumption in Bangladesh will diversify over time, cereals will provide a major part of the calorie intake, but their share in total calorie supply will decrease by 2030 and 2050. The consumption of animal products and non-cereal crops will have increasing trend during the same time period. The projections showed that Bangladesh will have surplus productions of rice and maize by 2030 and deficit productions of wheat, potato, pulses, vegetables, meat, egg and fresh water fish. It will have surplus productions of rice, maize, potato, vegetable and milk by 2050 and deficit productions of wheat, pulses, fruits, meat and fresh water fish. Water demand for Boro rice production in 2030 and 2050 will increase considerably and may cause much stress on ground water source.
