Abstract:

Purpose:This study aimed to describe the reverse digital artery cross-finger flap (RDAC flap) in the treatment of failed finger replantation.Methods:This study retrospectively reviewed the records of patients who underwent modified RDAC flap reconstructions for failed finger replantation and assessed their outcomes. Of the patients who underwent soft tissue reconstructions for finger injuries between March 2011 and February 2015, we enrolled 11 patients in whom RDAC flap reconstruction procedures were performed to treat the failed replantations.Results:The flaps survived in all cases, with a mean static, two-point discrimination value of 5.3 mm (range, 4–7 mm) in the healed flaps. The sizes of the flaps ranged from 2 × 1 cm2to 2.3 × 1.5 cm2.Conclusion:The RDAC flap was introduced by Lai et al., and it is a mixed form with the advantages of both cross-finger flap and heterodigital island flap. Our results suggest that it could provide reliable coverage of the sensate soft tissue of fingers with failed replantation.

Abstract:

Tracking the maximum output power of a photovoltaic (PV) cell is an important problem to harvest more energy at different weather and load conditions. This paper presents the design and simulation of a robust direct adaptive controller (RDAC) for maximum power point tracking (MPPT) device based on boost converter topology. A mathematical model is developed, and a suitable RDAC is designed for MPPT device, and simulations are performed using MATLAB/Simulink to verify the controller’s robustness at varying operating conditions. The real-time irradiance and temperature data are used on an hourly basis to test the suggested MPPT adaptive controller for a typical sunny day in summer and winter. The simulation results show that the RDAC performs excellent tracking under varying conditions such as irradiance, temperature, load, boost converter inductance, and capacitance.

Abstract:

As controlling temperature and humidity is crucial for maintaining comfort and preventing microbial growth, operating rooms (ORs) are the most energy-intensive areas in hospitals. We aimed to evaluate the energy consumption of three dehumidification air conditioning systems used in ORs and their corresponding air quality for ORs at rest. This study selected three ORs using a conventional heating, ventilation, and air conditioning (HVAC) system; a liquid desiccant air conditioning (LDAC) system; and a rotary desiccant air conditioning (RDAC) system, respectively. The indoor thermal–hygrometric conditions, air quality, and energy consumption of the ORs were monitored in this study. The median levels of relative humidity (RH) were 66.7% in the OR using the conventional HVAC system, 60.8% in the OR using the LDAC system, and 60.5% in the OR using the RDAC system. The median daily total energy consumption of the RDAC system (10.1 kWh/m2) and LDAC system (11.8 kWh/m2) were 28.12% and 16.54% lower, respectively, than that of the conventional HVAC system (14.1 kWh/m2). The PM≥0.5 levels and airborne bacterial concentrations in the ORs met the ISO 14644-1 Class 7 standard and China’s GB50333-2013 standard, respectively. The RDAC system was clearly superior to the LDAC and conventional HVAC systems in terms of energy consumption.

Abstract:

Data security in e-markets is vital to maintaining trust among trading partners. In an e-market, companies must share information to improve operational efficiency in their supply chains, while at the same time, access to sensitive information by rival companies should be prevented. In today’s highly dynamic business environment, the relationships among companies in e-markets are constantly changing while these relationships determine how company information should be shared with other companies. In this paper, the authors show that existing access control models are not designed for managing data security in e-markets with dynamic company relationships and propose a Relationship Driven Access Control (RDAC) model to provide a better solution. In particular, the authors design a rule-based approach for managing dynamic company relationships and a secure query processing mechanism to filter shared information based on company relationships. A prototype system is developed to demonstrate and validate the authors’ RDAC model.

Abstract:

This article charts the evolving role of Regional Development Agencies (RDAs) in Poland. It argues that changes to regional institutional and policy environments, linked to processes of regionalisation, EU accession, and the administration of European Union structural funds, have prompted increasing diversification of RDA activities. Moreover, questions of democratic accountability and economic efficiency are becoming increasingly pointed. Has regionalisation boosted the democratic accountability and regional orientation of agencies? Has administrative reform simplified agencies' delivery of development programmes? What influence has the administration of structural funds had on this? The article explores these issues, stressing generally that theoretical analyses of RDA activities must take increasing account of agency “positioning,” i.e., their role and purpose in an increasingly crowded and complex regional policy arena. Future scenarios for the evolution of RDAs in Poland are also outlined.

Abstract:

ABSTRACT The E2A-HLF fusion gene, formed by the t(17;19)(q22;p13) chromosomal translocation in leukemic pro-B cells, encodes a chimeric transcription factor consisting of the transactivation domain of E2A linked to the bZIP DNA-binding and protein dimerization domain of hepatic leukemia factor (HLF). This oncoprotein blocks apoptosis induced by growth factor deprivation or irradiation, but the mechanism for this effect remains unclear. We therefore performed representational difference analysis (RDA) to identify downstream genetic targets of E2A-HLF, using a murine FL5.12 pro-B cell line that had been stably transfected with E2A-HLF cDNA under the control of a zinc-regulated metallothionein promoter. Two RDA clones, designated RDA1 and RDA3, were differentially upregulated in E2A-HLF-positive cells after zinc induction. The corresponding cDNAs encoded two WD40 repeat-containing proteins, Grg2 and Grg6. Both are related to the Drosophila protein Groucho, a transcriptional corepressor that lacks DNA-binding activity on its own but can act in concert with other proteins to regulate embryologic development of the fly. Expression of both Grg2 and Grg6 was upregulated 10- to 50-fold by E2A-HLF. Immunoblot analysis detected increased amounts of two additional Groucho-related proteins, Grg1 and Grg4, in cells expressing E2A-HLF. A mutant E2A-HLF protein with a disabled DNA-binding region also mediated pro-B cell survival and activated Groucho-related genes. Among the transcription factors known to interact with Groucho-related protein, only RUNX1 was appreciably downregulated by E2A-HLF. Our results identify a highly conserved family of transcriptional corepressors that are activated by E2A-HLF, and they suggest that downregulation of RUNX1 may contribute to E2A-HLF-mediated leukemogenesis.

Abstract:

Background: Type 2 diabetes is a non-communicable disorder that requires changes in diet, among other aspects of lifestyle, in its management. Patients are normally advised on dietary intakes based on required dietary energy and nutrient intakes to normalise their conditions. Methods: The cross-sectional study recruited 100 adult type 2 diabetes patients by convenience sampling from Komfo Anokye Teaching Hospital, Kumasi, Ghana. The energy and nutrient intakes of patients were measured according to age and gender. The 24-hour recalls on three days per patient were used to access dietary intakes with references to Composition of Foods Commonly Used in Ghana, and the West African Food Composition Table. Meal skipping was noted. Anthropometric, blood pressure and biochemical measurements of patients were taken and related to their meal frequency lifestyle. The comparison of dietary intakes between males and females within age groups was done in reference to Recommended Daily Allowance (RDA) and Estimated Average Requirement (EAR), which are constituents of Dietary Reference Intakes (DRI). Results: Meal skipping was associated with a larger waste circumference. The mean daily protein intake (P = 0.001) and calcium intake (P = 0.004) of males were significantly higher than those of the females. Similarly, patients less than 60 years of age were more likely to consume more energy and nutrients (except calcium) than their older counterparts, though no significant differences were recorded. Mean quantities of carbohydrate, iron, and vitamin C consumed were above the DRI for both males and females. For dietary fibre, this was true only for females. The DRI for other nutrients was not met. For respondents <60 years, 45.5 %, 68.6 % and 72.7 % of males met their RDAs for protein, iron and vitamin C respectively while 41.7 %, 5.6 % and 80.6 % of their female counterparts met their RDA for these nutrients. For respondents ≥ 60 years, 46.7 %, 80 % and 66.7 % of males vs. 31.6 %, 63.2 %, and 92.1 % of females met their RDAs for protein, iron and vitamin C respectively. Only 2.8% of females < 60 years and 6.7 % of females ≥ 60 years met the RDA for vitamin E, while no males did. While 52.8 % of females < 60 years and 47.4% of those ≥ 60 years respectively met their RDAs for fibre, only 40 % males < 60 years met their RDA for fibre. All respondents met the RDA for carbohydrate except 2.6 % of females ≥ 60 years. For vitamin A, apart from 2.8 % of females < 60 years, no respondent met the RDA and for calcium none did. Conclusion: Both males and females had mean intakes of carbohydrate, iron, and vitamin C in excess of their DRI. The situation was problematic for other nutrients. Public and personal health and nutrition education should be intensified to promote adequate nutrient intakes among both male and female and younger and older age groups in diabetes patients in Ghana.

Abstract:

Abstract This paper reports the intakes of 72 nutrients and their dietary sources obtained from the Chinese total diet study in 1990. Most of the nutrient intakes are close or equal to their corresponding recommended daily allowances (RDAs). Both the total energy intake (2203 kcal) and the proportions contributed by protein, fat, and carbohydrate meet the current Chinese RDAs and the World Health Organization (WHO) nutrient goals. The average protein intake was 64 g/day. The intake of essential amino acids all exceeded the Chinese RDA, and their proportions were generally consistent with the WHO recommended pattern. The average fat intake was 51.2 g/day (21.2% of the total energy intake). However, the dietary fat intake has been increasing significantly in the Chinese diet and the proportion of animal fat has reached 53% of the total fat intake. The total saturated:total monounsaturated:total polyunsaturated fatty acid ratio was 1.0:1.5:1.0. Although the average cholesterol intake was only 179 mg/day, it was 248 mg/day in the South 1 region. The intakes of thiamine and riboflavin were below the RDA. Retinol intakes in all the 4 regions were low. Most (80%) of the retinol (equivalent) intakes were from carotenoids. The average intake of total tocopherol was 89% of the RDA, and among the 4 regions, only the South 2 region has relatively low intake. The intakes of iron, copper, manganese, sodium, and phosphorus were adequate. The intakes of calcium, zinc, and potassium were insufficient, and intakes of selenium and magnesium were a little low. High sodium and low potassium intake is a traditional problem in the Chinese diet.

Abstract:

Throughout the world, restoration of degraded areas (RDA) is not only a global but also a local challenge. In this context, the Brazilian government committed itself to restore 12 million hectares of forests by 2030. RDA monitoring customarily depends on extensive fieldwork to collect data on all individuals planted. As remotely piloted aircrafts (RPAs) can reduce costs and time of fieldwork activities, studying this technology is therefore timely given. A crucial metric for RDA is the number of trees established in the area. Methods using RPAs on automatic tree counting showed good accuracy using algorithms based on the canopy height model (CHM), which is the difference between a digital surface model (DSM) and a digital terrain model (DTM). However, obtaining a DTM demands an extra computational processing step and may require field control points or manually delimiting objects on the surface. The study presented here proposes and evaluates a semi-automated methodology for counting trees directly on DSM in RDAs in the Amazon using RPA coupled with a red–green–blue standard photographic sensor. The DSM method obtained good overall accuracy and F-score indexes, superior to the CHM method for all study areas even when overall accuracy was low for both methods.

Abstract:

This study was undertaken to investigate whether alcoholics differ qualitatively from controls in their organizational approach to the Rey–Osterrieth Complex Figure (ROCF) and to examine the effects of problem-solving and organizational ability on learning and retention. Data were collected on 3 groups of neuromedically healthy, middle-aged men: 29 recently detoxified alcoholics (RDA) abstinent at least 2 weeks, 29 long-term abstinent alcoholics (LTA) abstinent at least 18 months, and 29 nonalcoholic controls (NAC). Groups were comparable in age, education, WAIS–R Vocabulary score, and ANART IQ. Three indices of problem-solving approach were used to score how participants produce the ROCF during the copy condition: perceptual clustering, organization, and constructional accuracy. Learning and retention were measured by immediate recall, 20-min delayed recall, and recognition performance. RDAs had significantly impaired immediate recall, delayed recall, and recognition scores compared to NACs. RDAs also had significantly lower perceptual clustering, organization, and constructional accuracy scores than their long-term abstinent and nonalcoholic counterparts. Multiple regression analyses revealed that problem-solving ability at copy accounted for a significant proportion of the variance in immediate recall, delayed recall, and recognition. Further investigation of memory performance using a repeated measures design revealed that across the 3 groups, little forgetting occurred between immediate and delayed recall, while performance improved significantly on the recognition trial. Use of less efficient problem-solving strategies appears to affect RDAs' ability to learn and retrieve complex figural information. (JINS, 2000, 6, 12–19.)

Abstract:

The structure and function of forest ecosystems are directly or indirectly affected by their stand density. However, what effect the density of Chinese fir plantations has on the functional diversity of the soil microbial community remains unclear. The microbial metabolic functional diversity of soils sampled at the topsoil (0–20 cm) of 35-year-old Chinese fir plantations of five initial densities (D1: 1667 stems∙hm−2, D2: 3333 stems∙hm−2, D3: 5000 stems∙hm−2, D4: 6667 stems∙hm−2, and D5: 10,000 stems∙hm−2) was studied by using Biolog ECO technology. The results showed that the soil pH, oxidizable organic carbon (SOOC), available N (AN), available P (AP), and available K (AK) contents all showed a gradual increase from D1 to D4 and a decrease from D4 to D5, while the number of culturable bacteria and total microorganisms, the average well color development (AWCD) values for the single carbon substrate and six types of carbon sources used by the microbial community, as well as the Shannon-Wiener diversity index (H’), Pielou evenness index (J), and McIntosh Diversity Index (U), were the opposite, suggesting that low-densities favored C and N mineralization and the nutrient cycle. The density of Chinese fir plantations had a significant effect on the use of carbohydrates, amino acids, carboxylic acids, and phenolic acids by the soil microbial community, but it had no significant effect on the use of polymers (p < 0.05). Principal component analysis (PCA) revealed that carbohydrates, polymers, and phenolic acids were sensitive carbon sources that caused differences in the metabolic functions of soil microbial communities in Chinese fir plantations. Redundancy analysis (RDA) showed that physicochemical factors have a significant influence on the metabolic function of soil microbial communities (RDA1 and RDA2 explained >85% variance). The changes in density affected the soil physicochemical properties, the composition, and the metabolic functional diversity of microbial communities in Chinese fir plantations, which is certainly useful for the stand density regulation of Chinese fir plantations.

Abstract:

Iron fortification is an effective strategy that can be implemented to ensure supply and intake of iron for the public at large. Even though iron-fortified foods are widely available in the Sri Lankan market, the quantification of iron in those foods is not under the regulations of the food authorities in Sri Lanka. Therefore, this study aims to quantify the concentration of iron in selected iron-fortified foods available in the local market and determine their contribution to the recommended daily allowances (RDA) per serving. The iron content in most popular powdered milk, biscuits, and breakfast cereals among the children of 15-16 years in Horana Divisional Secretariat was analyzed using atomic absorption spectroscopy, and its contribution to RDA was calculated. The average iron values of iron-fortified milk powder (IFMP), iron-fortified biscuit (IFB), and iron-fortified breakfast cereals (IFBC) were found to be 18.08 ± 9.53, 7.88 ± 0.07, and 17.78 ± 7.47 mg/100 g, respectively. The average estimated daily intake (EDI) per serving of IFMP, IFB, and IFBC was 3.61 ± 1.75, 2.13 ± 0.06, and 5.60 ± 1.45 mg, respectively. The highest contribution to the RDA can be obtained by a single serving of IFBC. Only less than half of the tested products have compatible iron levels with their labeled information. Iron-fortified foods which were studied have a high amount of iron, and they can make from 5% to 35% contribution to RDAs in young children, adolescents, and adults even by a single serving.

Abstract. Mental illness is fundamentally mental, by definition about psychological rather than biological phenomena, but biological phenomena play key roles in understanding, preventing, and treating mental illness. The Research Domain Criteria (RDoC) initiative of the US National Institute of Mental Health (NIMH) is an unusually ambitious effort to foster integration of psychological and biological science in the service of psychopathology research. Some key features and common misunderstandings of RDoC are discussed here.

Abstract:

Daily intakes of 17 metals (boron, aluminium, chromium, manganese, nickel, copper, zinc, arsenic, selenium, molybdenum, cadmium, antimony, lead, uranium, magnesium, calcium, and iron) via drinking water and total diet were investigated in six cities in Japan. The daily metal intakes were estimated and compared with tolerable daily intake (TDI) values proposed by the WHO or Joint FAO/WHO Expert Committee on Food Additives for toxic metals and with recommended dietary allowances (RDAs) or adequate intake (AI) values proposed for essential metals by the Japanese Ministry of Health, Labour and Welfare. Among the 13 toxic metals, mean dietary intakes of 10 (except arsenic, selenium, and molybdenum) were less than 50% of TDI, suggesting that for these 10 metals the allocation of intake to drinking water in establishing guidelines or standards could possibly be increased from the normal allocation of 10–20% of TDI. For the 13 toxic metals, the contribution of drinking water to TDI was 2% or less in all six cities. Mean dietary intakes of the essential elements magnesium, calcium, and iron were less than the RDA or AI values. Drinking water did not contribute much to essential metal intake, accounting for less than 10% of RDA or AI.

Abstract:

At the behest of UNICEF, conceptual specifications from the International Workshop on Micronutrient Supplementation throughout the Life Cycle (held in Rio de Janeiro, Brazil, in November 1999) were developed for a chewable, flavored multiple-micronutrient vehicle that was a hybrid of a food and a tablet (i.e., “foodLET”). Two varieties of foodLET were created: one with a single infant–toddler RDA for selected micronutrients, and the other with two RDAs for the same vitamins and minerals. They were shipped and stored in special, hermetic blister packs to protect the physical form from crumbling and to protect the vitamins from oxidative damage. In the actual experience of delivering more than 40,000 foodLETs in four sites in diverse settings, the ability of the product to live up to the ideal characteristics can be assessed.

Abstract:

Summary It is well known that some psychological features of adolescents are positively associated with alcohol drinking but less attention is paid to the psychological features of their significant others. The aim of the study was to describe a common psychological profile of significant others to regularly alcohol drinking adolescents. A survey was conducted using an original questionnaire, which classifying alcohol drinking as regular, social (incidental) and abstinence. Of 903 students (aged 15-19), 169 identified themselves as regular drinkers (RDA) and 279 - as abstainers (NDA). The significant others of these two groups were compared statistically in terms of a wide range of psychological features. It was found that RDAs were significantly more likely to have: fathers (OR=1.94; 95% Cl 1.04-3.62) and friends (OR=l .55; 95% Cl 1.02-2.36) that tended to avoid obligations in favor of pleasure; extravert friends (OR=1.55; 95% Cl 1.06-2.28) and lovers (OR=1.72; 95% Cl 1.14-2.59); impulsive lovers (OR=l .76; 95% Cl 2.86- 1.08), and obeying (OR=l .95; 95% Cl 1.01-3.80) friends; conventional fathers (OR=2.17; 95% Cl 1.27-3.72) and less likely to have independent mothers (OR=0.57; 95% Cl 0.32-0.99) and hardworking friends (OR=0.58; 0.35- 0.95). It seems that significant others of RDAs are less likely to exhibit models of rational reactions in everyday life that prevent adolescents from developing rational personality, thus making it possible to increase the probability of regular drinking in adolescence.

Abstract:

AbstractObjective:To assess the energy and nutrient intakes of healthy infants from low-income families and to compare intakes with current recommendations.Design:We interviewed mother–infant pairs longitudinally when the infants were 3, 6, 9, 12, 18 and 24 months old. Food intake data were obtained by 24-hour dietary recalls. Selected nutrient intakes were calculated and compared with the Recommended Dietary Allowances (RDAs).Subjects/setting:Infants (n = 200) were the offspring of low-income, pregnant women recruited at the Albany County Department of Health, New York for the Albany Pregnancy and Infancy Lead Study, a prospective investigation of factors related to blood lead levels, including nutrition. Interviews were conducted during paediatric clinic visits.Statistical analyses performed:Means and standard deviations were used to describe energy and micronutrient intakes for age groups. The probability approach was utilised to examine the prevalence of inadequate intakes.Results:Mean energy and nutrient intakes generally met or exceeded the RDA. The exceptions were vitamin D and zinc for which observed means were below the RDA at several data points. Protein consumption was exceptionally high in this sample. The highest estimated prevalences of inadequate intakes were observed for iron, zinc and vitamin D at the older ages.Conclusions:This study identified several potential concerns about the diets of infants during the transition from infant food and formula to table foods. Low intakes of vitamin D, zinc and iron, especially at 12 and 18 months, were observed. High protein intakes were noted at all ages.

Abstract:

ABSTRACT Background Essential amino acids (EAAs) are key factors in determining dietary protein quality. Their RDAs have been estimated. However, although nonessential amino acids (NEAAs) are utilized for protein synthesis too, no estimates of their usage for body protein replenishment have been proposed so far. Objective The aim of this study was to provide minimum, approximate estimates of NEAA usage for body protein replenishment/conservation in humans. Methods A correlation between the pattern of both EAAs and NEAAs in body proteins, and their usage, was assumed. In order to reconstruct an “average” amino acid pattern/composition of total body proteins (as grams of amino acid per gram of protein), published data of relevant human organs/tissues (skeletal muscle, liver, kidney, gut, and collagen, making up ∼74% of total proteins) were retrieved. The (unknown) amino acid composition of residual proteins (∼26% of total proteins) was assumed to be the same as for the sum of the aforementioned organs excluding collagen. Using international EAA RDA values, an average ratio of EAA RDA to the calculated whole-body EAA composition was derived. This ratio was then used to back-calculate NEAA usage for protein replenishment. The data were calculated also using estimated organ/tissue amino acid turnover. Results The individual ratios of World Health Organization/Food and Agriculture Organization/United Nations University RDA to EAA content ranged between 1.35 (phenylalanine + tyrosine) and 3.68 (leucine), with a mean ± SD value of 2.72 ± 0.81. In a reference 70-kg subject, calculated NEAA usage for body protein replenishment ranged from 0.73 g/d for asparagine to 3.61 g/d for proline. Use of amino acid turnover data yielded similar results. Total NEAA usage for body protein replenishment was ∼19 g/d (45% of total NEAA intake), whereas ∼24 g/d was used for other routes. Conclusion This method may provide indirect minimum estimates of the usage of NEAAs for body protein replacement in humans.

Abstract:

Abstract Objectives To evaluate the nutrient adequacy of theoretical, modern-day Paleo meal plans relative to the U.S. Dietary Reference Intakes (DRIs). Methods This analysis used data from the Adhering to Dietary Approaches for Personal Taste (ADAPT) Feasibility Study, which captured data on 9 726 self-reported, popular diet followers. Paleo respondents (N = 925) reported sources of recipes and diet guidance. Five days from each of the top six sources were used to generate 30 days of meal plans among a random sample of n = 200 Paleo respondents. Nutrition Data System for Research (NDSR) was used to estimate daily nutrient content of meal plans which was compared to DRIs and recommendations, as follows: recommended daily allowances (RDAs) for vitamins D, E, and folate, which do not vary by age (years, y)/sex; sex and age-specific RDAs for vitamins A, C, calcium (Ca), magnesium (Mg), and iron (Fe); adequate intakes (AIs) for potassium (K) and fiber; upper intake level (UL) for sodium (Na); and Dietary Guidelines for Americans (DGA) upper threshold to limit saturated fat and Na. Results Estimated daily nutrient intakes of theoretical Paleo meal plans met or exceeded RDAs for the following (Paleo vs. RDA): vitamin A for men or women (1481 RAE µg vs. 900 μg and 700 µg), vitamin D (56 µg vs. 15 μg), vitamin E (27 mg vs. 15 mg), folate (489 µg vs. 400 μg), vitamin C for men or women (225 mg vs. 90 mg and 75 mg), Mg for men and women 31–70 y (539 mg vs. 420 mg and 320 mg), and Fe for men (16 mg vs. 8 mg). Theoretical estimates did not meet the following: RDAs for carbohydrate (91 g vs. 130 g), Fe for women 19–50 y (16 g vs.18 mg), Ca for men and women 61–70 y (562 mg vs. 1000 mg and 1200 mg), and AI for K (4027 mg vs. 4700 mg) or dietary fiber (25 g vs. 28 g/2000 kcal). Estimated levels of Na exceeded the UL (2763 mg vs. 2300 mg), saturated fat exceeded the DGA (19% vs. 10% kcal), and added sugar levels fell within the recommendation (1% vs. 10%). Conclusions While certain aspects of the Paleo diet offer improvements over typical reported intakes of US adults, saturated fat is high, and carbohydrate, fiber, Ca, and K levels of these theoretical diets do not meet DRIs. High levels of saturated fat present concern for cardiovascular health. Optimal nutrition may be challenging to sustain on a Paleo diet.

Abstract:

Abstract Objectives US children ages 4 and older use multivitamin/mineral supplements (MVMs) formulated to meet the Daily Values for adults. To better evaluate the potential for nutrient adequacy and excess, it is helpful to determine actual ingredient content instead of amounts declared on labels. We tested children's MVMs and compared the products’ labeled and measured contents with Recommended Dietary Allowances (RDA) and Upper Tolerable Intake Levels (UL) established for children ages 4 to 8 years. Methods Children's MVMs were defined as dietary supplements (DSs) containing three or more vitamins with or without minerals and other bioactive components labeled for individuals ages 4 and older. Nationally representative children's MVMs were identified based on relative market share estimates (RMSE) derived from frequency of use and respondents’ weights in infant/pediatric MVM subsets of 2003–2006 National Health and Nutrition Examination Surveys, and store surveys. The 21 top and 43 lower market share DSs selected for this study represented ∼72% of the total RMSE. The DSs were purchased in 2008 from multiple market channels in regions of AL, CA, MI, MO, NY, and OK identified using a multistage probability-proportional-to-size approach. Vitamin and mineral content was measured by commercial labs in 3 to 6 lots of 47 chewable tablets, 11 gummies, 4 liquids, 1 gumball, and 1 powder DS. Results For 13 of 16 nutrients (copper, iodine, iron, zinc, folic acid, niacin, riboflavin, thiamin, vitamins A, B-12, B-6, D and E), most MVMs were labeled at or above the RDA but below UL levels. For calcium, magnesium and phosphorus, all the studied DSs were labeled below the RDAs. The DSs that contained zinc, niacin and retinol labeled above their ULs had overall mean RMSEs comparable to the DSs labeled within the RDA-UL ranges. Overages resulted in levels exceeding the UL for folic acid in 24 out of 29 DSs labeled at the UL and for retinol in 10 out 40 DSs labeled below the UL, including one of the three most highly consumed MVMs. Conclusions The prevalence of children's MVMs on the US market with labeled levels at or above the RDA, or at UL, combined with analytically verified overages, suggests risks of excess in intakes for zinc, niacin, retinol and folic acid, especially when MVM use is combined with diets containing many highly fortified foods.

Abstract:

OBJETIVO: Determinar a relação entre o estado nutricional e a ingestão dietética de pacientes com fibrose cística. MÉTODOS: Estudo transversal com 85 pacientes com fibrose cística entre 6 e 18 anos de idade. A ingestão dietética foi avaliada pelo registro alimentar de 3 dias com a pesagem dos alimentos consumidos. Os desfechos avaliados foram os seguintes indicadores do estado nutricional: percentual da relação peso/estatura (%P/E), percentil do índice de massa corpórea (IMC), escore Z para estatura/idade (E/I) e peso/idade (P/I), e percentual de ingestão dietética comparada a Recommended Dietary Allowances (RDAs). RESULTADOS: A prevalência de pacientes eutróficos foi de 77,7%, considerando o IMC acima do percentil 25 como ponto de corte, e 83,5% estavam acima de 90% do %P/E. A média de ingestão, avaliada em 82 pacientes, foi de 124,5% da RDA. Nas análises de regressão logística univariada, encontrou-se uma associação significativa entre a variável independente ingestão calórica e o desfecho escore Z E/I. O modelo de análise multivariado, elaborado a partir do desfecho escore Z E/I e ajustado para idade, VEF1, colonização por Staphylococcus aureus resistente à meticilina e número de internações hospitalares, demonstrou que um aumento de 1% da ingestão calórica em relação à RDA diminui em 2% a chance de ter déficit de estatura (OR = 0,98; IC95%: 0,96-1,00). A escolaridade materna demonstrou uma associação limítrofe (p = 0,054). CONCLUSÕES: Houve baixa prevalência de desnutrição nesta amostra. O modelo de estudo demonstrou evidências da associação entre a ingestão dietética e o estado nutricional, sendo esta ingestão um fator preditor de crescimento nesses pacientes.

Abstract:

Abstract. Concentrations of recalcitrant and bioavailable dissolved organic carbon (DOC) and their seasonal variations were investigated at three stations in Tokyo Bay, Japan, and in two freshwater sources flowing into the bay. On average, recalcitrant DOC (RDOC), as a remnant of DOC after 150 days of bottle incubation, accounted for 78% of the total DOC in Shibaura sewage treatment plant (STP) effluent, 67% in the upper Arakawa River water, 66% in the lower Arakawa River water, and 78% in surface bay water. Bioavailable DOC (BDOC) concentrations, defined as DOC minus RDOC, were lower than RDOC at all stations. In freshwater environments, RDOC concentrations were almost constant throughout the year. In the bay, RDOC was higher during spring and summer than in autumn and winter because of freshwater input and biological production. The relative concentration of RDOC in the bay derived from phytoplankton, terrestrial, and open-oceanic waters was estimated to be 8–10, 21–32, and 59–69%, respectively, based on multiple regression analysis of RDOC, salinity, and chl a. In addition, comparison with previous data from 1972 revealed that concentrations of RDOC and BDOC have decreased by 33 and 74% at freshwater sites and 39 and 76% in Tokyo Bay, while the ratio of RDOC to DOC has increased. The change in DOC concentration and composition was probably due to increased amounts of STP effluent entering the system. Tokyo Bay exported mostly RDOC to the open ocean because of the remineralization of BDOC.
