Sample records for 24-hour dietary recall

  1. Validation of the Portuguese self-administered computerised 24-hour dietary recall among second-, third- and fourth-grade children

    Current methods for assessing children's dietary intake, such as interviewer-administered 24-h dietary recall (24-h DR), are time consuming and resource intensive. Self-administered instruments offer a low-cost diet assessment method for use with children. The present study assessed the validity of ...

    Full Text Available Abstract The objective of this study was to assess the agreement between the Brazilian Healthy Eating Index – Revised (BHEI-R, estimated by a food frequency questionnaire (FFQ and multiple 24-hour recalls (24h-R. The Wilcoxon paired test, partial correlations (PC, intraclass correlation coefficient (ICC, and Bland-Altman method were used. The total BHEI-R scores and its components (“total fruits”, “whole fruits”, “total vegetables”, “integral cereals”, “saturated fat”, “sodium”, and “energy intake derived from solid fat, added sugar, and alcoholic beverages” were statistically different, with the ICC and PC indicating poor concordance and correlation. The mean concordance estimated for the total BHEI-R and its components varied from 68% for “integral cereals” to 147% for “whole fruits”. The suitable concordance limits were violated for most of the components of the BHEI-R. Poor concordance was observed between the BHEI-R estimated by the FFQ and by multiple 24h-R, which indicated a strong reliability of the BHEI-R on the instrument used to collect information on food consumption.

    Full Text Available Maternal choline intake during the third trimester of human pregnancy can modify systemic and local epigenetic marks in fetal-derived tissues, promoting better pregnancy outcomes, increased immunity, as well as improved mental and physical work capacity with proper memory and cognitive development. 103 pregnant women presenting to the antenatal care of Azimpur Maternity Hospital of Dhaka, Bangladesh in their third trimester of pregnancy were randomly selected for this cross sectional study exploring dietary intake patterns of choline. A dietary recall form was administered to estimate frequency and amount of food consumption of foods for the previous 24 hours. Most women reported diets that delivered less than the recommended choline intake (mean ± SD; 189.5 ± 98.2 providing only 42.72% of total RDA value. The results of this study may indicate that dietary choline among pregnant, Bangladeshi women may not be adequate to meet the needs of both, the mother and fetus. Further studies are warranted to determine clinical implications. Normal 0 false false false MicrosoftInternetExplorer4

    Full Text Available The aim of this study was to develop, test, and evaluate a 24-h recall procedure to assess the dietary intake of toddlers of Somali- and Iraqi-born mothers living in Norway. A protocol for a 24-h multiple-pass recall procedure, registration forms, and visual tools (a picture library for food identification and portion size estimation was developed and tested in 12 mothers from Somalia and Iraq with children aged 10–21 months. Five female field workers were recruited and trained to conduct the interviews. Evaluation data for the 24-h recall procedure were collected from both the mothers and the field workers. Nutrient intake was calculated using a Norwegian dietary calculation system. Each child’s estimated energy intake was compared with its estimated energy requirement. Both the mothers and the field workers found the method feasible and the visual tools useful. The estimated energy intake corresponded well with the estimated energy requirement for most of the children (within mean ± 2 SD, except for three. The pilot study identified the need for additional foods in the picture library and some crucial aspects in training and supervising the field workers to reduce sources of error in the data collection.

  9. Evaluation study of the California Expanded Food and Nutrition Education Program: 24-hour food recall data.

    Del Tredici, A M; Joy, A B; Omelich, C L; Laughlin, S G

    1988-02-01

    The California Expanded Food and Nutrition Education program (EFNEP) Evaluation Study evaluated the effectiveness of the California program. The eating habits of 683 persons were studied in a group receiving EFNEP instruction (355 participants) and a control group (328 participants) that received no instruction. The 24-hour food recall was used to assess eating habits using the Synectics method. At the beginning of the study, there were no differences in food recall scores between the EFNEP and the control groups. After 6 months of instruction in the EFNEP group, there was a significant increase in food recall score for that group and no change in the control group. The improvements observed in the EFNEP group resulted from increased intakes from the milk, protein, and fruit and vegetable food groups. The program characteristics that led to those changes were determined to be in the length of the EFNEP visit, the number of EFNEP visits, and the EFNEP instruction topics. These results show that the California EFNEP is effective in producing significant changes in the eating habits of the low-income individuals it serves. PMID:3339205

  10. Assessment of energy and macronutrient intake in young men: a comparison of 4-day food record and 24-hour dietary recall Quantificação do consumo energético e de macronutrientes em homens jovens: uma comparação de 4 dias de registros alimentares e recordatório alimentar de 24 horas

    2009-10-01

    Full Text Available OBJECTIVE: The objective was to assess the quantitative agreement between a 4-day food record and a 24-hour dietary recall in young men. METHODS: Thirty-four healthy men aged 18-25 years had their food intake estimated by 4-day food record within one week following 24-hour dietary recall in a cross-sectional study. Resting metabolic rate was assessed by indirect calorimetry and Energy Expenditure was estimated by physical activity records completed simultaneously with food intake records. The validity of food records was determined by direct comparison of Energy Intake and Energy Expenditure (95% confidence interval for Energy Intake/Energy Expenditure. RESULTS: There were good agreements between the measurements of energy and macronutrient intakes by 24-hour dietary recall and 4-day food record at the group level, but not at the individual level. Compared to energy expenditure, about 20% and 9% of participants underreported their Energy Intake by 4-day food record and 24-hour dietary recall, respectively. Over 30% of underreporters of Energy Intake estimated by 24-hour dietary recall underreported Energy Intake estimated by 4-day food record. CONCLUSION: Both diet methods, 24-hour dietary recall and 4-day food record, may be used to collect data at the group level, but not at the individual level. Both methods, however, appear to underestimate Energy Intake. Underreporting may be subject-specific and appears that is more difficult to retrieve valid dietary data from some people than others.OBJETIVO: Medir a concordância qualitativa entre registros alimentares, obtidos durante 4 dias, e recordatório alimentar de 24 horas em homens jovens. MÉTODOS: Em um estudo com delineamento transversal, o consumo alimentar de 34 homens saudáveis com idades entre 18 e 25 anos foi medido por meio do recordatório alimentar de 24 horas e uma semana depois, por meio de 4 dias de registros alimentares. O gasto energético em repouso foi medido por calorimetria

    Full Text Available The objective of the present study was to evaluate energy intake (EI estimated from two non-consecutive 24-hour recalls (24-HDRs and a pre-coded seven-day food record (7-dFR against objective measurements of energy expenditure (EE in children.A total of 67 7–8 year-olds and 64 12–13 year-olds completed the 2×24-HDRs, the 7-dFR, and wore ActiReg® (PreMed AS, Oslo, Norway, a combined position and motion recording instrument, during the same seven days as the 7-dFR was filled in.In the 7–8 year-olds, EI from the 2×24-HDRs (EI2×24-HDR was overestimated with 3% compared to EE (not significantly different, while EI from the 7-dFR (EI7-dFR was underestimated with 7% compared to EE (P=0.001. In the 12–13 year-olds, the corresponding figures was underestimation by 10% with the 2×24-HDRs (P<0.001 and by 20% with the 7-dFR (P<0.001. For both age groups combined, the 95% limits of agreement were −4·38 and 3.52 MJ/d for the 2×24-HDRs, and −5.90 and 2.94 MJ/d for the 7-dFR. Pearson correlation coefficients between EI and EE were 0.51 for EI2×24-HDR and 0.29 for EI7-dFR, respectively. The proportion classified in the same or adjacent quartiles was 76% for EI2×24-HDR and 73% for EI7-dFR in the 7–8 year-olds, and 83% for EI2×24-HDR and 70% for EI7-dFR in the 12–13 year-olds.Misreporting of EI seemed modest with both the 2×24-HDRs and the 7-dFR in the 7–8 year-olds when compared to EE measured with ActiReg®. Under-reporting appeared to be more evident in the 12–13 year-olds, especially with the 7-dFR. Compared to measurements of EE, the 2×24-HDRs seemed to perform slightly better than the 7-dFR in terms of ranking of individuals according to EI.

  17. Effect of overtime work on 24-hour ambulatory blood pressure.

    Hayashi, T; Kobayashi, Y; Yamaoka, K; Yano, E

    1996-10-01

    Recently, the adverse effects of long working hours on the cardiovascular systems of workers in Japan, including "Karoshi" (death from overwork), have been the focus of social concern. However, conventional methods of health checkups are often unable to detect the early signs of such adverse effects. To evaluate the influence of overtime work on the cardiovascular system, we compared 24-hour blood pressure measurements among several groups of male white-collar workers. As a result, for those with normal blood pressure and those with mild hypertension, the 24-hour average blood pressure of the overtime groups was higher than that of the control groups; for those who periodically did overtime work, the 24-hour average blood pressure and heart rate during the busy period increased. These results indicate that the burden on the cardiovascular system of white-collar workers increases with overtime work. PMID:8899576

  19. Estimating 24-hour urinary sodium excretion from casual urinary sodium concentrations in Western populations

    Brown, Ian J; Dyer, Alan R; Chan, Queenie;

    2013-01-01

    High intakes of dietary sodium are associated with elevated blood pressure levels and an increased risk of cardiovascular disease. National and international guidelines recommend reduced sodium intake in the general population, which necessitates population-wide surveillance. We assessed the...... utility of casual (spot) urine specimens in estimating 24-hour urinary sodium excretion as a marker of sodium intake in the International Cooperative Study on Salt, Other Factors, and Blood Pressure. There were 5,693 participants recruited in 1984-1987 at the ages of 20-59 years from 29 North American and...... European samples. Participants were randomly assigned to test or validation data sets. Equations derived from casual urinary sodium concentration and other variables in the test data were applied to the validation data set. Correlations between observed and estimated 24-hour sodium excretion were 0.50 for...

    In the United States the preferred method of obtaining dietary intake data is the 24-hour dietary recall, yet the measure of most interest is usual or long-term average daily intake, which is impossible to measure. Thus, usual dietary intake is assessed with considerable measurement error. Also, diet represents numerous foods, nutrients and other components, each of which have distinctive attributes. Sometimes, it is useful to examine intake of these components separately, but increasingly nu...

    2014-09-01

    Full Text Available OBJECTIVE: To investigate the association between aggression in the first 24 hours after admission and severity of psychopathology in psychiatric inpatients.METHODS: This cross-sectional study included psychiatric patients admitted to Hospital Universitário de Santa Maria, in Santa Maria, southern Brazil, from August 2012 to January 2013. At their arrival at the hospital, patients were interviewed to fill in the Brief Psychiatric Rating Scale (BPRS form, and any aggressive episodes in the first 24 hours after admission were recorded using the Overt Aggression Scale (OAS. The Mann-Whitney U test was used to compare patients according to aggressiveness: aggressive versus non-aggressive, hostile versus violent, and aggressive against others only versus self-aggressive.RESULTS: The sample was composed of 110 patients. Aggressive patients in general had higher BPRS total scores (p = 0.002 and individual component scores, and their results showed more activation (p < 0.001 and thinking disorders (p = 0.009, but less anxious-depression (p = 0.008. Violent patients had more severe psychomotor agitation (p = 0.027, hallucinations (p = 0.017 and unusual thought content (p = 0.020. Additionally, self-aggressive patients had more disorientation (p = 0.011 and conceptual disorganization (p = 0.007.CONCLUSIONS: Aggression in psychiatric patients in the first 24 hours after admission is associated with severity of psychopathology, and severity increases with severity of patient psychosis and agitation.

  4. Breast milk intake: 12 hour versus 24 hour assessment.

    De Carvalho, M; Pittard, W

    1982-11-01

    Letter to the editor commenting on "Clinical and field studies of human lactation: methodological considerations," by Brown et al. The point is made that in test-weighing infants to estimate breast milk intake, culture related breastfeeding practices must be studied before a 12 hour test period is used to estimate intake for a complete 24 hour period. In western cultures milk intake between 7 am and 7 pm was found to differ significantly from intake between 7 pm and 7 am, whereas in a Bangladesh study milk intake during the 2 12 hour periods was comparable.

  5. The 24-hour society between myth and reality.

    Costa, G

    2001-12-01

    The 24-hour society appears to be an ineluctable process towards a social organisation where time constraints are no more "restricting" the human life. But, what kind of 24-hour society do we need? At what costs? Are they acceptable/sustainable? Shift work, night work, irregular and flexible working hours, together with new technologies, are the milestone of this epochal passage, of which shift workers are builders and victims at the same time. The borders between working and social times are no more fixed and rigidly determined: not only the link between work place and working hours is broken, but also the value of working time changes according to the different economic/productive/social effects it can make. What are the advantages and disadvantages for the individual, the companies, and the society? What is the cost/benefit ratio in terms of physical health; psychological well-being, family and social life? The research on irregular working hours and health shows us what can be the negative consequences of non-human-centered working times organisations. Coping properly with this process means avoiding a passive acceptance of it with consequent maladjustments at both individual and social level, but adopting effective preventive and compensative strategies aimed at building a more sustainable society, at acceptable costs and with the highest possible benefits.

    2016-01-01

    Survivor of a ship ground in polar regions may have to wait more than five days before being rescued. Therefore, the purpose of this study was to explore cognitive performance during prolonged cold exposure. Core temperature (Tc) and cognitive test battery (CTB) performance data were collected from eight participants during 24 hours of cold exposure (7.5°C ambient air temperature). Participants (recruited from those who have regular occupational exposure to cold) were instructed that they could freely engage in minimal exercise that was perceived to maintaining a tolerable level of thermal comfort. Despite the active engagement, test conditions were sufficient to significantly decrease Tc after exposure and to eliminate the typical 0.5–1.0°C circadian rise and drop in core temperature throughout a 24 h cycle. Results showed minimal changes in CTB performance regardless of exposure time. Based on the results, it is recommended that survivors who are waiting for rescue should be encouraged to engage in mild physical activity, which could have the benefit of maintaining metabolic heat production, improve motivation, and act as a distractor from cold discomfort. This recommendation should be taken into consideration during future research and when considering guidelines for mandatory survival equipment regarding cognitive performance. PMID:27478839

  14. Flexibility of working hours in the 24-hour society.

    Costa, G

    2006-01-01

    The 24-hour Society undergoes an ineluctable process towards a social organisation where time constraints are no more restricting human life. The borders between working and social times are no more fixed and rigidly determined, and the value of working time changes according to the different economic and social effects you may consider. Shift and night work, irregular and flexible working hours, together with new technologies, are the milestone of this epochal passage. What are the advantages and disadvantages for the individual, the companies, and the society? What is the cost/benefit ratio in terms of health and social well-being? Coping properly with this process means avoiding a passive acceptance of it with consequent maladjustments at both individual and social level, but adopting effective preventive and compensative strategies aimed at building up a more sustainable society. Flexible working times now appear to be one of the best ways to cope with the demands of the modern life, but there are different points of view about labour and temporal 'flexibility" between employers and employees. For the former it means a prompt adaptation to market demands and technological innovations; for the latter it is a way to improve working and social life, by decreasing work constraints and increasing control and autonomy. Although it can be easily speculated that individual-based 'flexibility" should improve health and well-being, and especially satisfaction, whereas company-based flexibility" might interfere negatively, the effective consequences on health and well-being have still to be analysed properly.

  15. Preparation and results of a 24-hour orbital flight.

    Titov, G S

    1963-01-01

    The space age presents man with unprecedented opportunities for discovery and for cooperative endeavors to benefit all mankind. My flight of August 6-7, 1961 was conducted for the purpose of determining whether man can stay and work effectively and whether all systems of the spaceship can operate successfully during a period of 24 hours in space. The flight of Vostok II represents an experimental step in a logical sequence which included the first earth orbiting flight of USSR citizen Yuri A. Gagarin. Preparation for the flight included the study of theoretical and applied subjects, testing in various kinds of apparatus which provide acceleration, heat and isolation experience, brief airborne weightless flights and parachute landings, in addition to extensive training in a real spacecraft having simulators for normal and emergency contingencies of space flight. The actual flight was therefore carried out with a sense of confidence and familiarity and with continuous close radio contact with ground centers from whom my fellow cosmonauts served as spokesmen. Sequential boosters totaling 600 000 kg thrust placed the 4731 kg spaceship into a perfect orbit varying in altitude from 178-246 km in a plane 64 degrees 58' inclined to the equator. The spaceship made 17 orbits around the earth landing 25 hours, 18 minutes after take-off. The cabin had full atmospheric pressure and a comfortable habitability which could be extended for 10 days. I was able to maneuver the spaceship and perform many other control functions, make observations and take pictures of the earth and its cloud cover, eat meals and sleep all with good efficiency. I experienced mild symptoms suggestive of seasickness which were aggravated by head turning, ameliorated by sleep and entirely relieved by resumption of g-loading during descent. Altogether analyses of the physical and structural performance of the spaceship and the continuously monitored physiological responses of the pilot indicate that all

The most accurate and valid diagnostic tool for epilepsy, is electroencephalography which provides details on the brain's function by recording brain cells' waves. Aim of the study was the exploration of the patients' total experience at a psychological and emotional level during a 24hour EEG. Materials and Methods: The sample included 40 subjects aged 18-40 years with a history or suspicion of epileptic symptoms. Due to the study's explorative/explicative nature, a qualitative research design was used. Data collection was performed through semi-structured interviews, direct observations and field notes. Following patients' permission, the interviews were recorded and the verbatim data was analyzed via thematic content analysis. Results: The verbatim text was the raw material where key words or phrases with autonomous meaning, relevant to the study's aims where subsequently organized in 4 major themes and 20 sub-categories, namely: Emotional-Psychological state (Positive: Joy, Optimism, Positive Thinking, Self-Confidence. Negative: Sadness, Anxiety, Fear, Panic, Pessimism. Behavior of patients (Calmness, Comfort, Nervousness, Aggravation. Options for patient involvement (TV, Reading, Music, Sleep, Lack of internet. Interpersonal relationships (family, friendly. Conclusions: During achieving the study's aims, many methodological and practical obstacles have been encountered as it proved to be particularly challenging to encompass patients' emotions and accurately cite their experiences during the EEG. However, results that have been revealed are adequate in formulating a holistic picture about the psychological state and the emotions that patients experience during the procedure.

    2015-01-01

    Past dietary patterns may be more important than recent dietary patterns in the aetiology of chronic diseases because of the long latency in their development. We developed an instrument to recall vegetarian dietary patterns during the lifetime and examined its reliability of recall over 5·3 and 32·6 years on average. The short-term/5-year recall ability study (5-RAS) was done using 24 690 participants from the cohort of the Adventist Health Study-2 (mean age 62·2 years). The long-term/33-year recall ability study (33-RAS) included an overlap population of 1721 individuals who joined the Adventist Health Study-1 and Adventist Health Study-2 (mean age 72·5 years). Spearman correlation coefficients for recall of vegetarian status were 0·78 and 0·72 for the 5-RAS and 33-RAS, respectively, when compared with 'reference' data. For both time periods sensitivity and positive predictive values were highest for the lacto-ovo-vegetarian and non-vegetarian patterns (vegans, lacto-ovo-vegetarians, pesco-vegetarians, semi-vegetarians and non-vegetarians). In the 5-RAS analyses, male, non-black, younger, and more educated participants, lifetime Adventists, and those with more stability of consumption of animal products generally showed higher recall ability. Somewhat similar tendencies were shown for the 33-RAS analyses. Our findings show that the instrument has higher reliability for recalled lacto-ovo-vegetarian and non-vegetarian than for vegan, semi- and pesco-vegetarian dietary patterns in both short- and long-term recalls. This is in part because these last dietary patterns were greatly contaminated by recalls that correctly would have belonged in the adjoining category that consumed more animal products.

    2009-10-01

    Full Text Available Abstract Background With an increasing focus on obesity prevention there is a need for simple, valid tools to assess dietary indicators that may be the targets of intervention programs. The objective of this study was to determine the relative validity of previous day dietary intake using a newly developed parent-proxy questionnaire (EPAQ for two to five year old children. Methods A convenience sample of participants (n = 90 recruited through preschools and the community in Geelong, Australia provided dietary data for their child via EPAQ and interviewer-administered 24-hour dietary recall (24 hr-recall. Comparison of mean food and beverage group servings between the EPAQ and 24 hr-recall was conducted and Spearman rank correlations were computed to examine the association between the two methods. Results Mean servings of food/beverage groups were comparable between methods for all groups except water, and significant correlations were found between the servings of food and beverages using the EPAQ and 24-hr recall methods (ranging from 0.57 to 0.88. Conclusion The EPAQ is a simple and useful population-level tool for estimating the intake of obesity-related foods and beverages in children aged two to five years. When compared with 24-hour recall data, the EPAQ produced an acceptable level of relative validity and this short survey has application for population monitoring and the evaluation of population-based obesity prevention interventions for young children.

    Mobile phones are becoming important instruments for assessing diet and energy intake. We developed the Tool for Energy Balance in Children (TECH), which uses a mobile phone to assess energy and food intake in pre-school children. The aims of this study were: (a) to compare energy intake (EI) using TECH with total energy expenditure (TEE) measured via doubly labelled water (DLW); and (b) to compare intakes of fruits, vegetables, fruit juice, sweetened beverages, candy, ice cream, and bakery products using TECH with intakes acquired by 24 h dietary recalls. Participants were 39 healthy, Swedish children (5.5 ± 0.5 years) within the ongoing Mobile-based Intervention Intended to Stop Obesity in Preschoolers (MINISTOP) obesity prevention trial. Energy and food intakes were assessed during four days using TECH and 24 h telephone dietary recalls. Mean EI (TECH) was not statistically different from TEE (DLW) (5820 ± 820 kJ/24 h and 6040 ± 680 kJ/24 h, respectively). No significant differences in the average food intakes using TECH and 24 h dietary recalls were found. All food intakes were correlated between TECH and the 24 h dietary recalls (ρ = 0.665-0.896, p < 0.001). In conclusion, TECH accurately estimated the average intakes of energy and selected foods and thus has the potential to be a useful tool for dietary studies in pre-school children, for example obesity prevention trials.

All food intakes were correlated between TECH and the 24 h dietary recalls (ρ = 0.665–0.896, p < 0.001. In conclusion, TECH accurately estimated the average intakes of energy and selected foods and thus has the potential to be a useful tool for dietary studies in pre-school children, for example obesity prevention trials.

    Full Text Available Abstract Background The incidence of Hypertension as a major cardiovascular threat is increasing. The best known diet for hypertensives is 'no added salt diet'. In this study we evaluated the effect of 'no added salt diet' on a hypertensive population with high dietary sodium intake by measuring 24 hour urinary sodium excretion. Methods In this single center randomized study 80 patients (60 cases and 20 controls not on any drug therapy for hypertension with mild to moderate hypertension were enrolled. 24 hour holter monitoring of BP and 24 hour urinary sodium excretion were measured before and after 6 weeks of 'no added salt diet'. Results There was no statistically significant difference between age, weight, sex, Hyperlipidemia, family history of hypertension, mean systolic and diastolic BP during the day and at night and mean urinary sodium excretion in 24 hour urine of case and control groups. Seventy eight percent of all patients had moderate to high salt intake. After 6 week of 'no added salt diet' systolic and diastolic BP significantly decreased during the day (mean decrease: 12.1/6.8 mmhg and at night (mean decrease: 11.1/5.9 mmhg which is statistically significant in comparison to control group (P 0.001 and 0.01. Urinary sodium excretion of 24 hour urine decreased by 37.1 meq/d ± 39,67 mg/dl in case group which is statistically significant in comparison to control group (p: 0.001. Only 36% of the patients, after no added salt diet, reached the pretreatment goal of 24 hour urinary sodium excretion of below 100 meq/dl (P:0.001. Conclusion Despite modest effect on dietary sodium restriction, no added salt diet significantly decreased systolic and diastolic BP and so it should be advised to every hypertensive patient.

    2015-01-01

    Preliminary research has suggested that wearable cameras may reduce under-reporting of energy intake (EI) in self-reported dietary assessment. The aim of the present study was to test the validity of a wearable camera-assisted 24 h dietary recall against the doubly labelled water (DLW) technique. Total energy expenditure (TEE) was assessed over 15 d using the DLW protocol among forty adults (n 20 males, age 35 (sd 17) years, BMI 27 (sd 4) kg/m2 and n 20 females, age 28 (sd 7) years, BMI 22 (sd 2) kg/m2). EI was assessed using three multiple-pass 24 h dietary recalls (MP24) on days 2-4, 8-10 and 13-15. On the days before each nutrition assessment, participants wore an automated wearable camera (SenseCam (SC)) in free-living conditions. The wearable camera images were viewed by the participants following the completion of the dietary recall, and their changes in self-reported intakes were recorded (MP24+SC). TEE and EI assessed by the MP24 and MP24+SC methods were compared. Among men, the MP24 and MP24+SC measures underestimated TEE by 17 and 9 %, respectively (Pimage sensors and increased imaging frequency may improve the accuracy further. PMID:25430667

  1. Assessment of 201Tl myocardial SPECT reinjected at 24 hours after stress imaging

    To improve the quality of 24 hours delayed images (24 DL) of stress thallium-201 myocardial SPECT, reinjection was performed at 24 hours later (24 RI), and the results were compared with those of 24 DL. A total of 45 patients were studied, including 18 patients in 24 DL, 27 patients in 24 RI. All of them showed persistent defect or incomplete redistribution on the routine stress and 3 hours delayed SPECT scans. In 24 RI, 37 MBq of thallium-201 was reinjected at 24 hours later. Myocardial count of 24 DL was about 1/4 of stress image, while 24 RI was about 1/2. Quality of 24 RI image was nearly equal to 3 hours delayed image. Of regions without redistribution on 3 hours delayed image, 5 (36%) regions showed new redistribution at 24 RI. Of regions incomplete redistribution, 6 (25%) regions showed further redistribution. Compared with 24 DL, the frequency of redistribution tended to be higher in this protocol than that of the 24 DL (11%, 17% respectively). In conclusion, the reinjection on 24 hours delayed imaging was considered to be useful to evaluate viability of myocardium in patients with CAD. (author)

  9. The use of multiple imputation method for the validation of 24-h food recalls by part-time observation of dietary intake in school.

    Kupek, Emil; de Assis, Maria Alice A

    2016-09-01

    External validation of food recall over 24 h in schoolchildren is often restricted to eating events in schools and is based on direct observation as the reference method. The aim of this study was to estimate the dietary intake out of school, and consequently the bias in such research design based on only part-time validated food recall, using multiple imputation (MI) conditioned on the information on child age, sex, BMI, family income, parental education and the school attended. The previous-day, web-based questionnaire WebCAAFE, structured as six meals/snacks and thirty-two foods/beverage, was answered by a sample of 7-11-year-old Brazilian schoolchildren (n 602) from five public schools. Food/beverage intake recalled by children was compared with the records provided by trained observers during school meals. Sensitivity analysis was performed with artificial data emulating those recalled by children on WebCAAFE in order to evaluate the impact of both differential and non-differential bias. Estimated bias was within ±30 % interval for 84·4 % of the thirty-two foods/beverages evaluated in WebCAAFE, and half of the latter reached statistical significance (P<0·05). Rarely (<3 %) consumed dietary items were often under-reported (fish/seafood, vegetable soup, cheese bread, French fries), whereas some of those most frequently reported (meat, bread/biscuits, fruits) showed large overestimation. Compared with the analysis restricted to fully validated data, MI reduced differential bias in sensitivity analysis but the bias still remained large in most cases. MI provided a suitable statistical framework for part-time validation design of dietary intake over six daily eating events. PMID:27452779

  10. [Identification of paroxysmal, transient arrhythmias: Intermittent registration more efficient than the 24-hour Holter monitoring].

    Hendrikx, Tijn; Rosenqvist, Mårten; Sandström, Herbert; Persson, Mats; Hörnsten, Rolf

    2015-01-01

    Many patients suffer from palpitations or dizziness/presyncope. These patients are often referred for Holter ECG (24 hour), although the sensitivity for detecting arrhythmias is low. A new method, short intermittent regular and symptomatic ECG registrations at home, might be a convenient and more sensitive alternative also suitable for primary health care. In this case report we present a patient who had contacted health care several times during a seven year period for paroxysmal palpitations. Routine examination with 24 hour Holter ECG and event recorder did not result in a diagnosis. Using intermittent handheld ECG registration at home, a paroxysmal supraventricular arrhythmia was diagnosed. Further investigation revealed that the patient had a concealed Wolff-Parkinson-White (WPW) syndrome. PMID:25584602

    1990-08-01

    Noninvasive 24-hour ambulatory blood pressure monitoring was performed in 17 normotensive and 19 preeclamptic pregnant women. The normotensive women showed a significant nightly decline in their systolic and diastolic blood pressure. In contrast, the preeclamptic women demonstrated either an attenuated circadian rhythm or no circadian rhythm at all. This result was even more pronounced in patients with severe hypertension, some of whom had a nocturnal increase in blood pressure in spite of being treated with antihypertensive drugs in an evening dose. The lack of nocturnal blood pressure decrease was also found 24 hours post partum. In summary, these results suggest that preeclamptic women are endangered by hypertensive emergencies mostly during the night. Therefore blood pressure controls should be extended into the night, and antihypertensive drugs should also be given in a sufficient evening dose. PMID:2214601

    2012-06-01

    Full Text Available Abstract Background This article concerns Swedish patients receiving 24-hour home care from health care assistants (HC assistants employed by the municipality. Home care is a complex interactive process involving the patient, family, HC assistants as well as professional care providers. Previous studies exploring patient perspectives on home care have been based mainly on patient interviews. In contrast, the present study took a broad perspective on patients’ experiences and thoughts by combining field observations on care situations with patient and HC assistant interviews. The aim of the study presented in this article was to promote a new and broadened understanding of patients receiving 24-hour home care by constructing a theoretical model to illuminate their main concern. Methods Field observations and semi-structured interviews were conducted with four patients receiving 24-hour home care and their HC assistants. Grounded theory methodology was used. Results The core process identified was Grasping the lifeline, which describes compensatory processes through which patients strived for control and safe care when experiencing a number of exposed states due to inadequate home care. Patients tried to take control by selecting their own HC assistants and sought safe hands by instructing untrained HC assistants in care procedures. When navigating the care system, the patients maintained contacts with professional care providers and coordinated their own care. When necessary, a devoted HC assistant could take over the navigating role. The results are illuminated in a theoretical model. Conclusions The results accentuate the importance to patients of participating in their own care, especially in the selection of HC assistants. The model illustrates some challenging areas for improvement within the organisation of 24-hour home care, such as personnel continuity and competence, collaboration, and routines for acute care. Furthermore, it may be

  1. Impedance and electrically evoked compound action potential (ECAP drop within 24 hours after cochlear implantation.

    Joshua Kuang-Chao Chen

    Full Text Available Previous animal study revealed that post-implantation electrical detection levels significantly declined within days. The impact of cochlear implant (CI insertion on human auditory pathway in terms of impedance and electrically evoked compound action potential (ECAP variation within hours after surgery remains unclear, since at this time frequency mapping can only commence weeks after implantation due to factors associated with wound conditions. The study presented our experiences with regards to initial switch-on within 24 hours, and thus the findings about the milieus inside cochlea within the first few hours after cochlear implantation in terms of impedance/ECAP fluctuations. The charts of fifty-four subjects with profound hearing impairment were studied. A minimal invasive approach was used for cochlear implantation, characterized by a small skin incision (≈ 2.5 cm and soft techniques for cochleostomy. Impedance/ECAP was measured intro-operatively and within 24 hours post-operatively. Initial mapping within 24 hours post-operatively was performed in all patients without major complications. Impedance/ECAP became significantly lower measured within 24 hours post-operatively as compared with intra-operatively (p<0.001. There were no differences between pre-operative and post-operative threshold for air-conduction hearing. A significant drop of impedance/ECAP in one day after cochlear implantation was revealed for the first time in human beings. Mechanisms could be related to the restoration of neuronal sensitivity to the electrical stimulation, and/or the interaction between the matrix enveloping the electrodes and the electrical stimulation of the initial switch-on. Less wound pain/swelling and soft techniques both contributed to the success of immediate initial mapping, which implied a stable micro-environment inside the cochlea despite electrodes insertion. Our research invites further studies to correlate initial impedance/ECAP changes

  2. A New Method to Make 24-Hour Urine Collection More Convenient: A Validity Study

    Pooneh Nabavizadeh

    2014-01-01

    Full Text Available Background and Objectives. This study proposes a novel urine collection device that can divide each urine collection into 20 parts and store and cool just one part. The aim of the current study is to compare measured biomarkers from the proposed urine collection device to those of conventional 24-hour sampling method. We also hypothesized that the new method would significantly increase patients’ adherence to the timed urine collection. Methods. Two 24-hour urine samples with the conventional method and with the new automated urine collection device that uses just one-twentieth of each void were obtained from 40 healthy volunteers. Urine parameters including volume, creatinine, and protein levels were compared between the two methods and the agreement of two measurements for each subject was reported through Bland-Altman plots. Results. Our results confirmed that for all three variables, there is a positive correlation P<0.001 between the two measurements and high degree of agreement could be seen in Bland-Altman plots. Moreover, more subjects reported the new method as “more convenient” for 24-hour urine collection. Conclusions. Our results clearly indicate that a fixed proportion of each void may significantly reduce the urine volume in timed collections and this, in turn, may increase subjects’ adherence to this difficult sampling.

  3. Mechanical properties of the aortic arterial wall during 24 hours: a preliminary study in conscious sheep

    Previous experiences in animals showed a different behavior between the variability of pressure, arterial diameter and elasticity when they were registered for a couple of hours. To better understand arterial mechanics variability, we propose to measure simultaneously aortic pressure and diameter during 24 hours in a sheep. For that purpose, we developed a portable prototype device. It allows continuously recording physiological signals throughout the day and storing them in a solid state memory for later analysis. Pulse wave velocity and Peterson modulus were assessed beat-to-beat as arterial stiffness indexes. We identified 53,762 heart beats during 24 hours that were separated into 2 groups: below or above median mean pressure (71 mmHg). Mean diameter, pulse wave velocity and Peterson modulus increased for higher pressure values (p<0.05) whereas heart rate slowed down (p<0.05). Pressure-diameter loops were successfully recreated all along the experience. This new methodology sets the basis for further experiences involving the estimation of 24 hours arterial mechanics variability.

  7. Tasimelteon for the treatment of non-24-hour sleep-wake disorder.

    Neubauer, D N

    2015-01-01

    Tasimelteon (Hetlioz®), a melatonin receptor agonist, is the first, and, at the time of the publication, the only drug to be approved by the U.S. Food and Drug Administration (FDA) for the treatment of non-24-hour sleep-wake disorder (non-24). This circadian rhythm disorder occurs most commonly in blind individuals without light perception, and it results from their inability to entrain to the 24-hour photoperiod, although the indication does not specify a particular patient population. Non-24 is characterized by a persistent cycle of nighttime insomnia and daytime sleepiness, alternating with asymptomatic periods depending on an individual's degree of circadian rhythm synchronization with the photoperiod at any particular time. Phase II clinical trials in healthy individuals confirmed the circadian phase-shifting potential of tasimelteon. Phase III trials in totally blind subjects diagnosed with non-24 demonstrated the efficacy of tasimelteon in reducing both nighttime wakefulness and daytime napping. Physiologic monitoring revealed that tasimelteon resulted in a higher proportion of individuals becoming entrained to the 24-hour cycle compared with placebo. Safety assessments indicated that tasimelteon is well tolerated, with the most common adverse events being headache, alanine aminotransferase elevation, nightmares or unusual dreams, and upper respiratory or urinary tract infections. Tasimelteon is available as a capsule in a single 20-mg dose and it must be obtained through Vanda Pharmaceutical's HetliozSolutions program with dispensing through a specialty pharmacy. Safety studies in blind individuals diagnosed with non-24 are ongoing and a future clinical trial with Smith-Magenis syndrome patients is planned. PMID:25685859

  8. RF measurement made over 24 hours around mobile telephone base station (MTBS) in Malaysia

    The fact that so many people use of mobile phone has been accompanied by public debate about possible adverse effects on human health. The concern relate to the emissions of radiofrequency (RF) radiation from the mobile phone and from the MTBS that receive and transmit the signal. A study had been carried out by Nuclear Malaysia with aims to assess the levels of radiofrequency radiation and to analyze the radiation pattern against time for period of 24 hours. The finding of this study confirms that the MTBS transmit radiofrequency radiation with low level and vary against time. (Author)

  9. Comparing Serum and 24-hour Urine Calcium between Preeclamptic and Non-preeclamptic Patients

    2014-02-01

    Results: No statistically significant difference was found between serum calcium means in the two groups (p=0.07, though mean of 24-hour urine calcium in preeclamptic patients was significantly lower than that of control group (p=0.0003. In preeclamptic group, the degree of hypocalciuria was related to disordered liver enzymes, serum creatinine greater than 1.2 mg/dl, thrombocytopenia and proteinuria more than 2g/24h. Conclusion: Preeclampsia is associated with hypocalciuria; the more hypocalciuria there exists , the more preeclampsia is observed.

  10. Fasting for 24 Hours Heightens Reward from Food and Food-Related Cues

    Cameron, Jameason D; Gary S. Goldfield; Finlayson, Graham; John E. Blundell; Doucet, Éric

    2014-01-01

    Introduction We examined the impact of a 24 hour complete fast (vs. fed state) on two measures of food reward: 1) ‘wanting’, as measured by response to food images and by the relative-reinforcing value of food (RRV), and 2) ‘liking’, as measured by response to food images and the hedonic evaluation of foods consumed. Methods Utilizing a randomized crossover design, 15 subjects (9 male; 6 female) aged 28.6±4.5 yrs with body mass index 25.3±1.4 kg/m2 were randomized and counterbalanced to norma...

  11. Fourth-grade children’s dietary recall accuracy for energy intake at school meals differs by social desirability and body mass index percentile in a study concerning retention interval

    Guinn, Caroline H.; Baxter, Suzanne D.; Royer, Julie A.; Hardin, James W.; Mackelprang, Alyssa J.; Smith, Albert F.

    2010-01-01

    Data from a study concerning retention interval and school-meal observation on children’s dietary recalls were used to investigate relationships of social desirability score (SDS) and body mass index percentile (BMI%) to recall accuracy for energy for observed (n=327) children, and to reported energy for observed and unobserved (n=152) children. Report rates (reported/observed) correlated negatively with SDS and BMI%. Correspondence rates (correctly reported/observed) correlated negatively wi...

  12. The regulation of subcutaneous adipose tissue blood flow in the ischaemic forefoot during 24 hours

    A method for continuous measurement of subcutaneous adipose tissue blood flow in the forefoot during 24 hours (SBF) is described. The method is based on the radioisotope wash-out principle using 133-Xenon. A portable semiconductor detector is placed just above a local depot of 1-2 μCi 133-Xenon in 0.1 ml isotonic saline injected into the subcutaneous adipose tissue in the forefoot. The detector is connected to a memory unit allowing for storage of data. Due to the short distance, the recorded elimination rate constant must be corrected for combined convection and diffusion of the radioactive indicator. After reconstructive vascular surgery, the 24-hour blood flow pattern normalized although the ankle/arm systolic blood pressure index did not come within normal range. SBF during day-time activities decreased by up to 50% postoperatively. This is caused by the reappearance of the local, sympathetic, veno-arteriolar vasoconstrictor response. During sleep SBF increased by 71%. The term postreconstructuve hyperamia seems improper, at least in a long-term context, normalization of preoperative ischaemia is a more correct notation. The coefficient of variation of nocturnal SBF was calculated to 10%. The method thus seems apt as a monitor in medical therapy for occlusive arterial disease. Changes of λ has, however, to be considered in each study. 94 refs. (EG)

    1999-03-01

    Intravenous propofol anesthesia is better than inhalational anesthesia for otologic surgery, but cost and intraoperative movement make this technique prohibitive. This study compares a propofol sandwich anesthetic with a total propofol or inhalational anesthetic for otologic surgery to determine which produces the best perioperative conditions and least expense. One hundred twenty patients undergoing ear surgery were randomly chosen to receive an anesthetic with either isoflurane (INHAL), total propofol (TPROP), or propofol used in conjunction with isoflurane (PSAND). Postoperative wakeup and the incidence and severity of nausea, vomiting, and pain were compared among groups. Antiemetic administration and discharge times from recovery and the hospital were also compared. The groups were similar, but anesthesia times were longer in the INHAL group. Emergence from anesthesia after PSAND or TPROP was more rapid than after INHAL. Recovery during the next 24 hours was associated with less nausea and vomiting with PSAND than with INHAL. The cost of the PSAND anesthetic was similar to that of INHAL, and both were less than TPROP. PSAND anesthesia may be similar to TPROP and better than INHAL for otologic procedures. PSAND was less expensive than TPROP and produced a similar recovery profile and antiemetic effect in the 24-hour period after surgery. PMID:10064647

  14. The Application of a Contact Lens Sensor in Detecting 24-Hour Intraocular Pressure-Related Patterns

    2016-01-01

    Glaucoma is one of the leading causes of blindness worldwide. Recent studies suggest that intraocular pressure (IOP) fluctuations, peaks, and rhythm are important factors in disease advancement. Yet, current glaucoma management remains hinged on single IOP measurements during clinic hours. To overcome this limitation, 24-hour IOP monitoring devices have been employed and include self-tonometry, permanent IOP, and temporary IOP monitoring. This review discusses each IOP measuring strategy and focuses on the recently FDA-approved contact lens sensor (CLS). The CLS records IOP-related ocular patterns for 24 hours continuously. Using the CLS, IOP-related parameters have been found to be associated with the rate of visual field progression in primary open-angle glaucoma, disease progression in primary angle-closure glaucoma, and various clinical variables in ocular hypertension. The CLS has been used to quantify blink rate and limbal strain and measure the circadian rhythm in a variety of disease states including normal-tension glaucoma and thyroid eye disease. The effects of various IOP-lowering interventions were also characterized using the CLS. CLS provides a unique, safe, and well-tolerated way to study IOP-related patterns in a wide range of disease states. IOP-related patterns may help identify patients most at risk for disease progression and assist with the development of tailored treatments. PMID:27525110

    Although reducing dietary salt consumption is the most cost-effective strategy for preventing progression of cardiovascular and renal disease, policy-based approaches to monitor sodium intake accurately and the understanding factors associated with excessive sodium intake for the improvement of public health are lacking. We investigated factors associated with high sodium intake based on the estimated 24-hour urinary sodium excretion, using data from the 2009 to 2011 Korea National Health and Nutrition Examination Survey (KNHANES). Among 21,199 adults (≥19 years of age) who participated in the 2009 to 2011 KNHANES, 18,000 participants (weighted n = 33,969,783) who completed urinary sodium and creatinine evaluations were analyzed in this study. The 24-hour urinary sodium excretion was estimated using Tanaka equation. The mean estimated 24-hour urinary sodium excretion level was 4349 (4286-4413) mg per day. Only 18.5% (weighted n = 6,298,481/3,396,973, unweighted n = 2898/18,000) of the study participants consumed less the 2000 mg sodium per day. Female gender (P intake ≥50 percentile (P obesity (P sodium intake, even after adjusting for potential confounders. Senior high school/college graduation in education and managers/professionals in occupation were associated with lower sodium intake (P sodium than those who were normotensive. However, those who receiving treatment for hypertension consumed less sodium than those who were normotensive (P sodium excretion. The logistic regression analysis for the highest estimated 24-hour urinary sodium excretion quartile (>6033 mg/day) using the abovementioned variables as covariates yielded identical results. Our data suggest that age, sex, education level, occupation, total energy intake, obesity, and hypertension management status are associated with excessive sodium intake in Korean adults using nationally representative data. Factors associated with high sodium intake should be considered in

  19. The 24-hour profiles of thyrotropin, throxine and triiodothyronine in goitrous and goitre-free Ugandans

    Plasma thyrotropin (TSH), thyroxine (T4) and triiodothyronine (T3) concentrations were measured by radioimmunoassay with commercial assay kits in serial blood samples collected over a 24-hour period from 6 normal and 6 clinically euthyroid but goitrous male Ugandan subjects. Measurements on normal subjects revealed two peaks in plasma TSH concentration, one at about 08.00 hrs, the other at about 20.00 hrs. Plasma T4 concentrations showed two corresponding peaks, while plasma T3 concentrations showed no discernable pattern. Measurement on goitrous subjects revealed only the earlier peak in plasma TSH concentration, while the pooled mean TSH concentration was lower than in normal subjects. Plasma T4 concentrations showed two peaks, as for normal subjects, but the pooled mean T4 concentration was also lower than in normal subjects. Measurements on plasma T3 concentration again showed no discernable pattern. The significance of these findings is discussed

  20. The effect of Operation 24 Hours on reducing collision in the City of Edmonton.

    Halim, Siana; Jiang, Heming

    2013-09-01

    In the City of Edmonton, in order to reduce the prevalence of collisions, the Operation 24 Hours program (OPS24) was developed by using existing police and transportation services resources. The program uses traditional manned police speed enforcement method, which are supplemented by traffic safety messages displayed on permanent and mobile dynamic messaging signs (DMS). In this paper, collision data analysis was performed by looking at the daily number of collisions from 2008 to 2011 that covers 28 Operation 24 Hours (OPS24) events. The objective of the collision data analysis is to analyze if there is a reduction in collision frequencies after OPS24 was held and examined how long the collision reduction effect last. Weather factors such as temperature, thickness of snow, and wind gust have been considered by many as a great influence on collision occurrences, especially in a city with long and cold winter such as Edmonton. Therefore, collision modeling was performed by considering these external weather factors. To analyze the linear and periodic trend of different collision types (injury, fatal, and property damage only (PDO)) and examine the influence of weather factors on collisions, negative binomial time series model that accounts for seasonality and weather factors was used to model daily collision data. The modeling also considered collision proportion to account for missing traffic volume data; the Gaussian time series model that accounts for seasonality and weather factors was used to model collision proportion. To estimate the collision trend and test for changes in collision levels before/after OPS24, interrupted time series model with segmented regression was used. While for estimating how long the effect of the OPS24 last, change point method was applied. PMID:23727551

  1. A 24-Hour Study of the Hypothalamo-Pituitary Axes in Huntington's Disease.

    Eirini Kalliolia

    Full Text Available Huntington's disease is an inherited neurodegenerative disorder characterised by motor, cognitive and psychiatric disturbances. Patients exhibit other symptoms including sleep and mood disturbances, muscle atrophy and weight loss which may be linked to hypothalamic pathology and dysfunction of hypothalamo-pituitary axes.We studied neuroendocrine profiles of corticotropic, somatotropic and gonadotropic hypothalamo-pituitary axes hormones over a 24-hour period in controlled environment in 15 healthy controls, 14 premanifest and 13 stage II/III Huntington's disease subjects. We also quantified fasting levels of vasopressin, oestradiol, testosterone, dehydroepiandrosterone sulphate, thyroid stimulating hormone, free triiodothyronine, free total thyroxine, prolactin, adrenaline and noradrenaline. Somatotropic axis hormones, growth hormone releasing hormone, insulin-like growth factor-1 and insulin-like factor binding protein-3 were quantified at 06:00 (fasting, 15:00 and 23:00. A battery of clinical tests, including neurological rating and function scales were performed.24-hour concentrations of adrenocorticotropic hormone, cortisol, luteinizing hormone and follicle-stimulating hormone did not differ significantly between the Huntington's disease group and controls. Daytime growth hormone secretion was similar in control and Huntington's disease subjects. Stage II/III Huntington's disease subjects had lower concentration of post-sleep growth hormone pulse and higher insulin-like growth factor-1:growth hormone ratio which did not reach significance. In Huntington's disease subjects, baseline levels of hypothalamo-pituitary axis hormones measured did not significantly differ from those of healthy controls.The relatively small subject group means that the study may not detect subtle perturbations in hormone concentrations. A targeted study of the somatotropic axis in larger cohorts may be warranted. However, the lack of significant results despite many

    Full Text Available INTRODUCTION: We examined the impact of a 24 hour complete fast (vs. fed state on two measures of food reward: 1 'wanting', as measured by response to food images and by the relative-reinforcing value of food (RRV, and 2 'liking', as measured by response to food images and the hedonic evaluation of foods consumed. METHODS: Utilizing a randomized crossover design, 15 subjects (9 male; 6 female aged 28.6±4.5 yrs with body mass index 25.3±1.4 kg/m(2 were randomized and counterbalanced to normal feeding (FED and 24-hour fast (FASTED conditions. Trait characteristics were measured with the Three Factor Eating Questionnaire. Two computer tasks measured food reward: 1 RRV progressive ratio task, 2 explicit 'liking' and 'wanting' (Leeds Food Preference Questionnaire, LFPQ. Also measured were ad libitum energy intake (EI; buffet and food 'liking' (visual analogue scale of personalized stimuli. RESULTS: There were no significant anthropometric changes between conditions. Appetite scores, hedonic ratings of 'liking', and ad libitum EI all significantly increased under the FASTED condition (p<0.05. Under the FASTED condition there were significant increases in the RRV of snack foods; similarly, explicit 'wanting' and 'liking' significantly increased for all food categories. 'Liking' of sweet foods remained high across-meals under FASTED, but savory foods decreased in hedonic saliency. CONCLUSION: Relative to a fed state, we observed an increase in hedonic ratings of food, the rewarding value of food, and food intake after a 24 hr fast. Alliesthesia to food and food cues is suggested by heightened hedonic ratings under the FASTED condition relative to FED.

    Background Estimation of food portion sizes has always been a challenge in dietary studies on free-living individuals. The aim of this work was to develop and validate a food photography manual to improve the accuracy of the estimated size of consumed food portions. Methods A manual was compiled from digital photos of foods commonly consumed by the Tunisian population. The food was cooked and weighed before taking digital photographs of three portion sizes. The manual was validated by comparing the method of 24-hour recall (using photos) to the reference method [food weighing (FW)]. In both the methods, the comparison focused on food intake amounts as well as nutritional issues. Validity was assessed by Bland–Altman limits of agreement. In total, 31 male and female volunteers aged 9–89 participated in the study. Results We focused on eight food categories and compared their estimated amounts (using the 24-hour recall method) to those actually consumed (using FW). Animal products and sweets were underestimated, whereas pasta, bread, vegetables, fruits, and dairy products were overestimated. However, the difference between the two methods is not statistically significant except for pasta (ptest agreement highlights the lack of difference between the two methods. Conclusion The difference between the 24-hour recall method using digital photos and the weighing method is acceptable. Our findings indicate that the food photography manual can be a useful tool for quantifying food portion sizes in epidemiological dietary surveys. PMID:27585631

    Studies have examined nutrient differences among people following different plant-based diets. However, all of these studies have been observational. The aim of the present study was to examine differences in nutrient intake and Dietary Inflammatory Index (DII) scores among overweight and obese (body mass index 25.0-49.9 kg/m(2)) adults randomized to receive dietary instruction on a vegan (n = 12), vegetarian (n = 13), pescovegetarian (n = 13), semivegetarian (n = 13), or omnivorous (n = 12) diet during a 6-month randomized controlled trial. Nutrient intake, nutrient adequacy, and DII score were assessed via two 24-hour dietary recalls (Automated Self-Administered 24-Hour Dietary Recall) at baseline and at 2 and 6 months. Differences in nutrient intake and the DII were examined using general linear models with follow-up tests at each time point. We hypothesized that individuals randomized to the vegan diet would have lower DII scores and greater improvements in fiber, carbohydrate, fat, saturated fat, and cholesterol at both 2 and 6 months as compared with the other 4 diets. Participants randomized to the vegan diet had significantly greater changes in most macronutrients at both time points, including fat and saturated fat, as well as cholesterol and, at 2 months, fiber, as compared with most of the other diet groups (Ps Vegan, vegetarian, and pescovegetarian participants all saw significant improvements in the DII score as compared with semivegetarian participants at 2 months (Ps vegan and vegetarian diets, should be given consideration.

    2016-01-01

    Allergic diseases such as asthma and rhinitis are common in many countries. Globally the most common allergen associated with symptoms is produced by house dust mites. Although the bed has often been cited as the main site of exposure to mite allergens, surprisingly this has not yet been directly established by measurement due to a lack of suitable methods. Here we report on the development of novel methods to determine the pattern of personal exposure to mite allergen bioaerosols over 24-hour periods and applied this in a small field study using 10 normal adults. Air was sampled using a miniature time-based air-sampler of in-house design located close to the breathing zone of the participants, co-located with a miniature time-lapse camera. Airborne particles, drawn into the sampler at 2L/min via a narrow slot, were impacted onto the peripheral surface of a disk mounted on the hour-hand of either a 12 or 24 hour clock motor. The impaction surface was either an electret cloth, or an adhesive film; both novel for these purposes. Following a review of the time-lapse images, disks were post-hoc cut into subsamples corresponding to eight predetermined categories of indoor or outdoor location, extracted and analysed for mite allergen Der p 1 by an amplified ELISA. Allergen was detected in 57.2% of the total of 353 subsamples collected during 20 days of sampling. Exposure patterns varied over time. Higher concentrations of airborne mite allergen were typically measured in samples collected from domestic locations in the day and evening. Indoor domestic Der p 1 exposures accounted for 59.5% of total exposure, whereas total in-bed-asleep exposure, which varied 80 fold between individuals, accounted overall for 9.85% of total exposure, suggesting beds are not often the main site of exposure. This study establishes the feasibility of novel methods for determining the time-geography of personal exposure to many bioaerosols and identifies new areas for future technical

  11. Non-24-Hour Sleep-Wake Disorder Revisited – A Case Study

    Garbazza, Corrado; Bromundt, Vivien; Eckert, Anne; Brunner, Daniel P.; Meier, Fides; Hackethal, Sandra; Cajochen, Christian

    2016-01-01

    The human sleep-wake cycle is governed by two major factors: a homeostatic hourglass process (process S), which rises linearly during the day, and a circadian process C, which determines the timing of sleep in a ~24-h rhythm in accordance to the external light–dark (LD) cycle. While both individual processes are fairly well characterized, the exact nature of their interaction remains unclear. The circadian rhythm is generated by the suprachiasmatic nucleus (“master clock”) of the anterior hypothalamus, through cell-autonomous feedback loops of DNA transcription and translation. While the phase length (tau) of the cycle is relatively stable and genetically determined, the phase of the clock is reset by external stimuli (“zeitgebers”), the most important being the LD cycle. Misalignments of the internal rhythm with the LD cycle can lead to various somatic complaints and to the development of circadian rhythm sleep disorders (CRSD). Non-24-hour sleep-wake disorders (N24HSWD) is a CRSD affecting up to 50% of totally blind patients and characterized by the inability to maintain a stable entrainment of the typically long circadian rhythm (tau > 24.5 h) to the LD cycle. The disease is rare in sighted individuals and the pathophysiology less well understood. Here, we present the case of a 40-year-old sighted male, who developed a misalignment of the internal clock with the external LD cycle following the treatment for Hodgkin’s lymphoma (ABVD regimen, four cycles and AVD regimen, four cycles). A thorough clinical assessment, including actigraphy, melatonin profiles and polysomnography led to the diagnosis of non-24-hour sleep-wake disorders (N24HSWD) with a free-running rhythm of tau = 25.27 h. A therapeutic intervention with bright light therapy (30 min, 10,000 lux) in the morning and melatonin administration (0.5–0.75 mg) in the evening failed to entrain the free-running rhythm, although a longer treatment duration and more intense therapy

    Esophageal multiple intraluminal impedance baseline is an additional impedance parameter that was recently related to esophageal integrity. The aim of this study was to assess the relationship between mean esophageal impedance value and endoscopic findings in a large group of children. Children with symptoms of gastroesophageal reflux submitted to both endoscopy and impedance were included. Esophagitis was graded according to the Los Angeles classification. Mean impedance value was automatically calculated over 24-hour tracings. Data were adjusted for age through z-score transformation using percentiles normalized by the LMS (Lambda for the skew, Mu for the median, and Sigma for the generalized coefficient of variation) method. Nonparametric Mann-Whitney and Kruskal-Wallis tests, multiple, and stepwise regression were used. P-value reflux episodes were the variables that were significantly associated with the baseline z-score. Impedance z-score is significantly decreased in infants and children with endoscopic esophagitis. Severity of esophagitis, bolus exposure index, and number of reflux episodes are factors influencing mean esophageal impedance. PMID:25345864

    Three pH electrodes in clinical use were examined--(1) antimony electrode with remote reference electrode (Synectics 0011), (2) glass electrode with remote reference electrode (Microelectrodes Inc. MI 506) and (3) combined glass electrode with integral reference electrode (Radiometer GK2801C). In vitro studies showed that both glass electrodes were similar and superior to the antimony electrode with respect to response time, drift, and sensitivity. The effect of the siting of the reference electrode on the recorded pH was examined in five human volunteers. The pH reading using a remote skin reference electrode was higher by a mean of 0.3 pH units (range 0.0-0.6) in the stomach, lower by 0.65 pH units (0.5-0.8) in the duodenum and lower by 0.3 pH units (0.0-0.6) in the oesophagus than that simultaneously obtained with an intraluminal reference electrode. Buccal reference electrodes gave similar readings to skin. Combined reference and glass pH electrodes are recommended for 24-hour ambulatory pH monitoring. PMID:3666560

  14. 24 hours in the life of HIV-1 in a T cell line.

    2013-01-01

    Full Text Available HIV-1 infects CD4+ T cells and completes its replication cycle in approximately 24 hours. We employed repeated measurements in a standardized cell system and rigorous mathematical modeling to characterize the emergence of the viral replication intermediates and their impact on the cellular transcriptional response with high temporal resolution. We observed 7,991 (73% of the 10,958 expressed genes to be modulated in concordance with key steps of viral replication. Fifty-two percent of the overall variability in the host transcriptome was explained by linear regression on the viral life cycle. This profound perturbation of cellular physiology was investigated in the light of several regulatory mechanisms, including transcription factors, miRNAs, host-pathogen interaction, and proviral integration. Key features were validated in primary CD4+ T cells, and with viral constructs using alternative entry strategies. We propose a model of early massive cellular shutdown and progressive upregulation of the cellular machinery to complete the viral life cycle.

    In the present work, we development a new protocol for liver decellularization in which the hole decellularization was reached over 24 h. Introduction: the availability of transplantable livers is not sufficient to fulfill the current demand for grafts, with the search for therapeutic alternatives having generated different lines of research, one of which is the use of decellularized three-dimensional biological matrices and subsequent cell seeding to obtain a functional organ. Objective: to produce a decellularization protocol from rabbit liver to generate a three-dimensional matrixin which the time period involved didn't pass 24 h. Methods: The decellularization is obtained through the use of water and SDS (0,1-0,3 %), after freezing at -80 degrees, is the best alternative of different physical and/or chemical mechanisms to break down organ cells and leave only the extracellular matriz. After 24 h of retrograde perfusion, a decellularized translucent matrix was generated. To evaluate if the decellularization protocol was successful, with the extracellular matrix being preserved, we carried out histological (light microscopy) and biochemical (DNA quantification) studies. Results: the decellularization process was verified by macroscopic observation of the organ using microscopic observation corroborated the macroscopic results, with the hematoxylin-eosin and Masson staining showing no cells or nuclear material. In addition, the DNA quantification was less than 10% in the decellularized liver compared to control. Finally,the time taken to develop the decellularization protocol was less than 24 hours.

    A system has been developed which permits continuous 24 hour ambulatory recording of intragastric pH under near-physiological conditions. The system utilises a Cecar combination pH electrode connected through a pre-amplifier to an Oxford Medical Systems Medilog 4-24 cassette recorder, and the pH recorded continuously on to tape. The data is replayed at high speed, digitised and then analysed. Sources of error included system drift, system noise and the effect of changes in electrode environment due to saliva, food, loss of fluid contact, temperature variations and electrode time constant. These were found to be small. In contrast, the major changes in pH detected reflect real changes at the electrode tip. These changes can be recorded by the system. Developments in electronics and improvements in both the size and quality of pH electrodes, over the past few decades, has enabled intragastric pH recordings to be made with greater ease. However, a large number of investigators still assess gastric acidity by infrequent, intermittent sampling of gastric secretion through a naso-gastric tube. This new ambulatory system is a significant improvement and its versatility allows studies in acid secretion physiology, pharmacology and pathophysiology. PMID:3595080

  17. Pathophysiological changes detected by MRI within 24 hours after head injury

    This report concerns the evaluation of the usefulness of high-field magnetic resonance imaging (MRI) for the diagnosis and prognosis of patients with head injuries. For this purpose we compared the CT and MRI results obtained on 48 such patients. MRI of all cases was taken within 24 hours after head injury using a 1.5-Tesla unit. The sensitivity of the two modalities in the detection of small traumatic lesions was compared. Traumatic lesions of 23 patients (47.9%) were not detected by CT, but they were demonstrated on MRI. Overall, MRI was significantly more sensitive than CT in detecting early and/or subtle traumatic changes of the brain parenchyma (P1-WI and T2-WI. (B) Corpus callosum lesions with hyperintensity on T2-WI were in fact hemorrhagic contusions by signal changes on sequential MRI. The follow-up of chronological changes of a given corpus callosum lesion was essential for confirmation of its pathology. (C) In one case, scratch-like lesions with strong hypointensity on T1-WI and hyperintensity on T2-WI were clearly demonstrated in the white matter. These observations appeared to indicate axonal damages. (D) Even if initial GCS score is low (2-WI and subsequently disappeared completely. We conclude that performing MRI in the early stage of a head injury is of utility for the understanding of pertinent pathophysiological changes and for predicting outcome. (author)

    Full Text Available Disturbances in circadian rhythm might play a central role in the neurobiology of depression. We examined the association between depressive symptoms and 24-hour ambulatory BP in a sample of 405 (197 black and 208 Caucasian urbanized African teachers aged 25 to 60 yrs (mean 44.6 ± 9.6 yrs. Depressive symptoms were assessed using the self-administered 9-item Patient Health Questionnaire (PHQ-9. After adjusting for age, sex, and ethnicity, participants with severe depressive symptoms (PHQ-9 ≥ 15 had higher odds of hypertension defined from ambulatory BP and/or use of antihypertensive medication (odds ratio = 2.19, 95% CI, 1.00–4.90 in comparison to participants with no symptoms. Compared to Caucasians with no depressive symptoms, those with severe symptoms had blunted nocturnal systolic BP drop of 4.7 mmHg (95% CI, −0.5 to 10.0, P=0.07. In summary, depressive symptoms were associated with the circadian BP profile in black and Caucasian Africans.

  19. Importance of all movement behaviors in a 24 hour period for overall health.

    Chaput, Jean-Philippe; Carson, Valerie; Gray, Casey E; Tremblay, Mark S

    2014-12-01

    Physical inactivity and childhood obesity are well-recognized public health concerns that are associated with a range of adverse health outcomes. Historically, the benefits of physical activity (e.g., moderate-to-vigorous physical activity-MVPA) to overall health have dominated discussions and emerging evidence indicates that a broader, more integrated approach is needed to better understand and address current public health crises. Existing guidelines for children and youth around the world only focus on MVPA, and recently sedentary behavior, despite an accumulating body of evidence showing that light-intensity physical activity (LPA) such as walking can provide important health benefits. Furthermore, there is accumulating support for the importance of adequate sleep and that these behaviors moderate the health impact of each other. Ignoring the other components of the movement continuum (i.e., sleep, sedentary time, LPA) while focusing efforts exclusively on MVPA (accounting for <5% of the time in a 24 h period) limits the potential to optimize the health benefits of movement behaviors. In order to address this limitation, experts in Canada are currently developing the world's first Integrated 24 Hour Movement Behaviour Guidelines for Children and Youth to help advance an integrated healthy active living agenda that has the potential to significantly improve the overall health and well-being of children and youth.

  20. Prediction of late (24-hour) radioactive iodine uptake using early (3-hour) uptake values in Japanese patients with Graves' disease

    Measurement of 24-hour radioactive iodine uptake (RAIU), which is commonly used to calculate the dose of radioiodine (RI) therapy, cannot be accomplished in a single day. The purpose of this study was to predict 24-hour RAIU from 3-hour RAIU in Japanese patients with Graves' disease, and to investigate other factors that could be used to predict 24-hour RAIU. A total of 66 Japanese patients (14 men and 52 women; age, 17-83 years) with Graves' disease who had undergone both 3-hour and 24-hour 123I RAIU measurements between January 2006 and September 2011 were included in this study. Stepwise multiple regression analyses were performed in order to identify factors that could be used to predict 24-hour RAIU. The investigated factors were gender, age, thyroid volume, thyroid stimulating hormone (TSH), free thyroxine (FT4), free triiodothyronine (FT3), serum creatinine, second generation assay TSH receptor antibody (TRAb2), antithyroid drugs discontinuation period (ADP), iodine restriction period and 3-hour RAIU. The ADP was converted to an ordinal scale ADP score (ADPS) for multiple regression analyses. Multiple regression analyses showed that 3-hour RAIU (P10 EU +23.0 x log10 FT3 -2.7 x ADPS (r=0.82, P<0.001). The present results indicate that prediction of LU from EU, FT3 and ADPS is feasible in Japanese patients with Graves' disease. (author)

    2010-01-01

    We examined the effects of recall on symptom severity ratings by comparing ratings made using 24-hour and 7-day recall periods of the M. D. Anderson Symptom Inventory (MDASI). Forty-two patients in their third to eighth week of chemoradiation rated their symptoms using the MDASI on two separate occasions (T1 and T2), one week apart. At T1, patients were randomly assigned to rate symptoms using either a 24-hour or a 7-day recall. At T2, patients rated symptoms using the recall period not used ...

    Dietary components are important determinants of systemic inflammation, a risk factor for most chronic diseases. The Dietary Inflammatory Index (DII) was developed to assess dietary inflammatory potential. It was hypothesized that anti-inflammatory DII scores would be associated with "healthier" scores on other dietary indices. The Energy Balance Study is an observational study focusing on energy intake and expenditure in young adults; only baseline data were used for this analysis (n=430). The DII, as well as the Healthy Eating Index-2010 (HEI-2010), the Alternative Healthy Eating Index (AHEI), and the Dietary Approaches to Stop Hypertension Index (DASH) were calculated based on one to three 24-hour dietary recalls. General linear models were used to estimate least square means of the AHEI, HEI-2010, and DASH according to DII quartiles. Those with higher (ie, more proinflammatory) DII scores were more likely to be males, have less than a completed college education, and be younger. In addition, those with higher scores for cognitive restraint for eating or drive for thinness had lower (ie, anti-inflammatory) DII scores. Linear regression analyses indicated that as the DII increased, the AHEI, HEI-2010, and DASH dietary indices decreased (ie, became more unhealthy, all Pfactor for chronic disease. PMID:26923507

  5. 24 hour ST segment analysis in transient left ventricular apical ballooning.

    Frank Bode

    Full Text Available OBJECTIVE: The etiologic basis of transient left ventricular apical ballooning, a novel cardiac syndrome, is not clear. Among the proposed pathomechanisms is coronary vasospasm. Long-term ST segment analysis may detect vasospastic episodes but has not been reported. METHODS: 30 consecutive patients with transient left ventricular apical ballooning, left ventricular dysfunction and normal or near-normal coronary arteries were investigated. A 24-hour Holter ECG was obtained after emergency admission. ST segment analysis was performed automatically in 2 leads and confirmed by visual inspection. Criteria for an ischemic event were: 1. ST elevation or 2. horizontal or down-sloping ST segments ≥1 min duration and ≥100 µV J+80 point deviation corrected for baseline ST-deviation. RESULTS: Patients presented with ST segment elevation (n = 19 and/or T wave inversion (n = 20 on admission ECG. Ejection fraction was 50±12%. No transient ST elevations were observed during Holter ECG analysis. In 3 patients, 8 transient episodes of ST depression were recorded. Durations of episodes varied between 75 s and 790 s (mean 229 s. Maximal ST deviation averaged -191±71 µV. Ischemic burden was -1 to -22 mVs (mean -8 mVs. 27 patients showed no ischemic events. CONCLUSIONS: ST segment analysis of 24 h Holter recordings revealed minor ischemic events in only 10% of patients with transient left ventricular apical ballooning. Overall, ST segment changes were not indicative of recurrent coronary spasm playing a major role in the genesis of transient left ventricular apical ballooning.

  6. PATTERNS OF THE MAXIMUM RAINFALL AMOUNTS REGISTERED IN 24 HOURS WITHIN THE OLTENIA PLAIN

    2012-03-01

    Full Text Available Patterns of the maximum rainfall amounts registered in 24 hours within the Oltenia Plain. The present study aims at rendering the main features of the maximum rainfall amounts registered in 24 h within the Oltenia Plain. We used 30-year time series (1980-2009 for seven meteorological stations. Generally, the maximum amounts in 24 h display the same pattern as the monthly mean amounts, namely higher values in the interval May-October. In terms of mean values, the highest amounts are registered in the western and northern extremity of the plain. The maximum values generally exceed 70 mm at all meteorological stations: D.T. Severin, 224 mm, July 1999; Slatina, 104.8 mm, August 2002; Caracal, 92.2 m, July 1991; Bechet, 80.8 mm, July 2006; Craiova, 77.6 mm, April 2003. During the cold season, there was noticed a greater uniformity all over the plain, due to the cyclonic origin of rainfalls compared to the warm season, when thermal convection is quite active and it triggers local showers. In order to better emphasize the peculiarities of this parameter, we have calculated the frequency on different value classes (eight classes, as well as the probability of appearance of different amounts. Thus, it resulted that the highest frequency (25-35% is held by the first two classes of values (0-10 mm; 10.1-20 mm. The lowest frequency is registered in case of the amounts of more than 100 mm, which generally display a probability of occurrence of less than 1% and only in the western and eastern extremities of the plain.

  7. Weight/age-dependent glucose turnover (GTO) in fed and 24 hour fasted rats

    In small animals such as the rat, cardiac output and oxygen consumption are constant with age when normalized to the body surface area but not to body weight (BW). The authors explored this relationship for GTO in pentobarbital-anesthetized fed and 24 hours fasted Sprague-Dawley rats weighing between 200 and 55 g. A bolus of 10 μCi/kg BW of [6-3H]-glucose was injected into the carotid artery followed by a constant infusion equal to 1.5 μCi/minute *kg BW and samples taken from the right atrium every 15 minutes for glucose specific activity (SA) measurements over a 2 period. Steady state measurements of GTO (μmol/minute) plotted as a function of BW (g) revealed GTO to be inversely related in fed rats but independent of BW in fasted rats. Although plasma [glucose] was significantly lower in fasted rats, there were no weight related differences within each group. Fasting decreased GTO across the whole range of body weights; however, the magnitude of the fasting effect was much larger in the smaller animals (50% lower) compared to the larger animals (25% lower). Although the lean body mass is increasing in this range of BW, the decrease in GTO indicates an age/weight-related decrease in glucose utilization which diminishes the effect of fasting as the animal grows. This data explains the inconsistency in the literature regarding the fasting effect on GTO in the rat and emphasizes the importance of weight/age matching of experimental groups to minimize the variability in the data when GTO is of interest

  8. Office and 24-hour heart rate and target organ damage in hypertensive patients

    García-García Ángel

    2012-03-01

    Full Text Available Abstract Background We investigated the association between heart rate and its variability with the parameters that assess vascular, renal and cardiac target organ damage. Methods A cross-sectional study was performed including a consecutive sample of 360 hypertensive patients without heart rate lowering drugs (aged 56 ± 11 years, 64.2% male. Heart rate (HR and its standard deviation (HRV in clinical and 24-hour ambulatory monitoring were evaluated. Renal damage was assessed by glomerular filtration rate and albumin/creatinine ratio; vascular damage by carotid intima-media thickness and ankle/brachial index; and cardiac damage by the Cornell voltage-duration product and left ventricular mass index. Results There was a positive correlation between ambulatory, but not clinical, heart rate and its standard deviation with glomerular filtration rate, and a negative correlation with carotid intima-media thickness, and night/day ratio of systolic and diastolic blood pressure. There was no correlation with albumin/creatinine ratio, ankle/brachial index, Cornell voltage-duration product or left ventricular mass index. In the multiple linear regression analysis, after adjusting for age, the association of glomerular filtration rate and intima-media thickness with ambulatory heart rate and its standard deviation was lost. According to the logistic regression analysis, the predictors of any target organ damage were age (OR = 1.034 and 1.033 and night/day systolic blood pressure ratio (OR = 1.425 and 1.512. Neither 24 HR nor 24 HRV reached statistical significance. Conclusions High ambulatory heart rate and its variability, but not clinical HR, are associated with decreased carotid intima-media thickness and a higher glomerular filtration rate, although this is lost after adjusting for age.

    2012-01-01

    Full Text Available Background: A large number of persons with psychiatric disorders are not seeking treatment due to various reasons, thus contributing to the huge treatment gap. One of the ways to bring these people into treatment is through telephonic helplines. Materials and Methods: Following a large number of suicides in the city of Chandigarh in 2003, The department of Psychiatry, GMCH, Chandigarh was designated as nodal center for the prevention of suicide. A 24-hour suicide prevention helpline was set up as an immediate measure to help persons in crisis. Apart from providing telephonic counseling to persons in crisis, the helpline coordinated with police, media, schools, radio stations etc., to reduce the number of suicides in the city. Results: Majority of the callers were males (65.93%, between 20 to 39 years old (56.34%, married (79.50%, had less than 12 years of formal education (60.68%, and were earning less than Rs. 5000/month (56.80%. 72.96% callers had contacted the mental health services for the first time. A significant number of persons (434, 13.26% called the helpline for marital, academic, stress-related problems. Majority of the calls were received between 8 A.M. and 2 P.M. The number of suicides in the city of Chandigarh showed a decline in the following years since the helpline was set up. Conclusions: The telephonic helpline seems to be a very effective way of getting persons into contact with health services. They are cost-effective, the person can maintain his confidentiality and devoid of stigma.

    2012-05-01

    Full Text Available OBJECTIVE: Autonomic nervous system dysfunction (ASD has been widely observed in patients with type 2 diabetes. 24-hour ambulatory blood pressure (ABP and heart rate measurements have been found to associate with ASD in patient with Type 2 diabetes. Since albumin excretion is also related with ASD in type 2 diabetes; in the current study, the relationships between daytime, nighttime and 24- hour heart rates with 24 hour urinary albumin excretion (UAE and 24-hour urinary protein excretion (UPE were analyzed in patients with newly diagnosed type 2 diabetes. MATERIAL and METHODS: All patients underwent following procedures: history taking, physical examination, BP measurement, 12 lead electrocardiographic evaluations, routine urine analysis, biochemical analysis, 24-hour urine collection to measure UAE, UPE and creatinine clearance. 24-hour ABP and heart rate monitoring were performed for all patients. RESULTS: In total 80 patients with newly diagnosed type 2 diabetes were included. Stepwise linear regression revealed that logarithmically converted 24-hour UAE were independently related with 24- hour ambulatory SBP, (P:0.001 and heart rate (night (P<0.0001. Stepwise linear regression revealed that logarithmically converted 24-hour UPE were independently related with age (P:0.032, with averaged fasting blood glucose (P:0.023, with 24-hour ambulatory SBP, (P:0.002 and with heart rate (night (P:0.001. CONCLUSION: Nighttime heart rate, but not daytime and 24-hour heart rate was related with both 24-hour UAE and UPE in patients with Type 2 diabetes.

  11. Executive functions are not affected by 24 hours of sleep deprivation: A color-word stroop task study

    Abhinav Dixit

    2015-01-01

    Full Text Available Background: Sleep is an important factor affecting cognitive performance. Sleep deprivation results in fatigue, lack of concentration, confusion and sleepiness along with anxiety, depression and irritability. Sleep deprivation can have serious consequences in professions like armed forces and medicine where quick decisions and actions need to be taken. Color-Word Stroop task is one of the reliable tests to assess attention and it analyzes the processing of information in two dimensions i.e., reading of words and naming of colour. The evidence regarding the effect of sleep deprivation on Stroop interference is conflicting. The present study evaluated the effect of 24 hours of sleep deprivation on reaction time and interference in Stroop task. Materials and Methods : The present study was done on 30 healthy male medical student volunteers in the age group of 18-25 years after taking their consent and clearance from Institute Ethics Committee. Recordings of Stroop task were at three times: baseline (between 7-9 am, after 12 hours (7-9 pm and after 24 hours (7-9 am, next day. The subjects were allowed to perform normal daily activities. Results: The study revealed a significant increase in reaction time after 24 hours of sleep deprivation in comparison to baseline and after 12 hours of sleep deprivation. There was no significant change in interference and facilitation after sleep deprivation in comparison to baseline. The number of errors also did not show any significant change after sleep deprivation. Conclusion: The study indicated that there was slowing of responses without change in executive functions after 24 hours of sleep deprivation. It is probable that 24 hours of sleep deprivation does not bring about change in areas of brain affecting executive functions in healthy individuals who have normal sleep cycle. The present study indicated that in professions like armed forces and medicine working 24 hours at a stretch can lead to decrease in

    1995-01-01

    The authors have developed a method for estimating the distribution of an unobservable random variable from data that are subject to considerable measurement error and that arise from a mixture of two populations, one having a single-valued distribution and the other having a continuous unimodal distribution. The method requires that at least two positive intakes be recorded for a subset of the subjects in order to estimate the variance components for the measurement error model. Published in...

    Children's dietary intake is a key variable in evaluations of school-based interventions. Current methods for assessing children's intake, such as 24-hour recalls and meal observations, are time- and resource-intensive. As part of a study to evaluate the impact of farm-to-school programs, the school lunch recall was developed from a need for a valid and efficient tool to assess school lunch intake among large samples of children. A self-administered paper-and-pencil questionnaire, the school lunch recall prompts for school lunch items by asking children whether they chose a menu item, how much of it they ate, how much they liked it, and whether they would choose it again. The school lunch recall was validated during summer school in 2008 with 18 third- to fifth-grade students (8 to 11 years old) in a North Carolina elementary school. For 4 consecutive days, trained observers recorded foods and amounts students ate during school lunch. Students completed the school lunch recall immediately after lunch. Thirty-seven total observation school lunch recall sets were analyzed. Comparison of school lunch recalls against observations indicated high accuracy, with means of 6% for omission rate (items observed but unreported), 10% for intrusion rate (items unobserved but reported), and 0.63 servings for total inaccuracy (a measure that combines errors for reporting items and amounts). For amounts, accuracy was high for matches (0.06 and 0.01 servings for absolute and arithmetic differences, respectively) but lower for omissions (0.47 servings) and intrusions (0.54 servings). In this pilot study, the school lunch recall was a valid, efficient tool for assessing school lunch intake for a small sample of third- to fifth-grade students. PMID:21338742

    Full Text Available To find shortest and reliable time period of urine collection for determination of proteinuria.It is a prospective study carried out on 125 pregnant women with preeclampsia after 20 weeks of gestation having urine albumin >1 using dipstick test. Urine was collected in five different time intervals in colors labeled containers with the assistance of nursing staff; the total collection time was 24 hours. Total urine protein of two-hour, four-hour, eight-hour, 12-hour and 24-hour urine was measured and compared with 24-hour collection. Data was analyzed using the Pearson correlation coefficient.There was significant correlation (p value < 0.01 in two, four, eight and 12-hour urine protein with 24-urine protein, with correlation coefficient of 0.97, 0.97, 0.96 and 0.97, respectively. When a cut off value of 25 mg, 50 mg. 100 mg, and 150 mg for urine protein were used for 2-hour, 4-hours, 8-hour and 12-hour urine collection, a sensitivity of 92.45%, 95.28%, 91.51%, and 96.23% and a specificity of 68.42%, 94.74%, 84.21% and 84.21% were obtained, respectively.Two-hour urine proteins can be used for assessment of proteinuria in preeclampsia instead of gold standard 24-hour urine collection for early diagnosis and better patient compliance.

  20. GFR, serum creatinine and 24-hour urine protein in evaluating renal function of patients with diabetes mellitus

    Background: Diabetes nephropathy is a common complication of diabetes mellitus patients. Early detection of renal impairment can improve the quality of life of patients. Purpose: The value of total GFR, serum creatinine, 24-hour urine protein excretion in diabetes mellitus patients with renal impairment were evaluated. Methods: A retrospective analysis of 147 patients with diabetes undergoing routine renal dynamic imaging was undertaken. The cases were divided into three groups according to the illness duration: group I of not more than five years, group 2 of five to ten years, Gr.3: more than ten years. The 22 renal transplant donors were selected as the normal control group, The total GFR, serum creatinine and 24-hour urinary protein excretion of all patients were measured before the treatments, and the data were statistically analyzed. Results: There was no significant differences in renal function between the two kidneys of in the diabetes mellitus patients (P=0.536). Serum creatinine and total GFR had significant correlation (R2=0.762), but no significant relationship between the 24-hour urine protein and the total GFR or serum creatinine. In the early and middle times of renal function impairment, the total GFR and serum creatinine have significant difference in different time periods (P<0.05). During the mid-late times of renal function impairment, total GFR and serum creatinine have no statistically significant differences (P value is 0.781, 0.297). 24-hour urine protein quality had no statistical differences in each stage. However: the total GFR is more sensitive than the serum creatinine in evaluation of early impairing of renal function. Conclusions: There is significant correlation between serum creatinine and total GFR. Both of them can reflect the degree of diabetic renal injury, but the total GFR is more sensitive than serum creatinine in early degree. 24-hour urine protein quantitative can not evaluate the degree of impaired renal function alone

  1. Value of 24-hour Delayed Film of Barium Enema for Evaluation of Colon Transit Function in Young Children with Constipation

    2016-01-01

    Background/Aims A colon transit time test using radio-opaque markers (CTTRM) is considered the gold standard for evaluating colon transit function. A 24-hour delayed film of barium enema (BE) has been used as a supplementary method in structural evaluations. The aim of this study was to evaluate the utility of a 24-hour delayed BE film for assessing colon transit function in young children with constipation. Methods In total, 93 children with constipation who performed both single-contrast BE and CTTRM were enrolled in this study. Of these, the data from 70 children were analyzed (males 33, females 37; mean age [range], 5.63 ± 2.94 [2–14] years). The basic principle of the study is “velocity = distance/time”. Time values were identified in both studies, and the colon length and distance of barium movement were measured on the 24-hour delayed BE film. Thus, colon transit velocity values could be calculated using both methods. The correlation between colon transit velocity using a 24-hour delayed BE film versus CTTRM was analyzed statistically. Results Median value (interquartile range) of colon transit velocity using CTTRM was 1.57 (1.07–2.89) cm/hr, and that using BE of that was 1.58 (0.94–2.07) cm/hr. The Spearman correlation coefficient was 0.438 (P children younger than 4 years (r = 0.537, P = 0.032). Conclusions Although the correlation between BE and CTTRM was not very strong, the 24-hour delayed BE film could provide broad information about colon transit function in young children, especially those under 4 years who usually cannot undergo CTTRM.

    2016-01-01

    Background: Monitoring the health status of patients discharged from intensive care units is a crucial method of service evaluation. Objectives: This study aimed to assess the physical and mental health status of patients immediately after discharge from the ICU and 24 hours later. Patients and Methods: This descriptive comparative study was conducted on 104 patients discharged from the ICUs of a referral trauma center in Shiraz, Southwest Iran. Physical parameters, including respiratory rate, need for supplemental oxygen, heart rate, blood pressure, and need for cardiac monitoring, were assessed. Hospital anxiety and depression scale (HADS) was used for mental health evaluation. The mental and physical status of patients were assessed before ICU discharge and 24 hours later; data were recorded in information forms and were analyzed using SPSS statistical software version 17. Results: At the time of discharge, the respiratory rate of 28% of the participants was more than 24 minutes, and 95.2% received supplemental oxygen. However, after 24 hours these values decreased to 10% and 21.6%, respectively. The mean heart rate and systolic blood pressure were within the normal range at both time points. Additionally, 63% of the patients had anxiety scores above 11 at both time points, reflecting high anxiety. The number of patients who reported depression increased from 58.7% at ICU discharge to 69.6% after 24 hours. Conclusions: Despite the considerable improvement in most of the patients’ physical condition in the first 24 hours after discharge from ICU, a significant number of them remain at risk for the development of adverse effects from this transition. The high prevalence of mental health disorders in these patients reveals the necessity to conduct follow-up consultations.

    Full Text Available Microleakage is a main cause of restorative treatment failure. In this study, we compared occlusal and cervical microleakage of two self-adhesive cements after 24 hours and two months.In this in-vitro experimental study, class II inlay cavities were prepared on 60 sound human third molars. Composite inlays were fabricated with Z100 composite resin. The teeth were randomly assigned to six groups. RelyX-Arc (control, RelyX-Unicem and Maxcem were used for the first three groups and specimens were stored in distilled water at 37°C for 24 hours. The same cements were used for the remaining three groups, but the specimens were stored for 2 months. The teeth were subjected to 500 thermal cycles (5°C and 55°C and immersed in 0.5% basic fuchsin for 24 hours and then sectioned mesiodistally and dye penetration was evaluated in a class II cavity with occlusal and cervical margins using X20 magnification stereomicroscope. Data were analyzed using Kruskal Wallis and Mann-Whitney U tests.After 24 hours, cements had significant differences only in cervical margin microleakage (P=0.0001 and microleakage of RelyX-Unicem and Maxcem was significantly more than that of RelyX-Arc (both P=0.0001. Cervical microleakage in RelyX-Unicem and Maxcem was greater than occlusal (P=0.0001 and P=0.001, respectively. Microleakage was not significantly different between the occlusal and cervical margins after 2 months.Cervical microleakage was greater than occlusal in RelyX-Unicem and Maxcem after 24h. The greatest microleakage was reported for the cervical margin of RelyX-Unicem after 24 hours.

  4. Estimating the Distribution of Dietary Consumption Patterns

    Carroll, Raymond J.

    2014-02-01

    In the United States the preferred method of obtaining dietary intake data is the 24-hour dietary recall, yet the measure of most interest is usual or long-term average daily intake, which is impossible to measure. Thus, usual dietary intake is assessed with considerable measurement error. We were interested in estimating the population distribution of the Healthy Eating Index-2005 (HEI-2005), a multi-component dietary quality index involving ratios of interrelated dietary components to energy, among children aged 2-8 in the United States, using a national survey and incorporating survey weights. We developed a highly nonlinear, multivariate zero-inflated data model with measurement error to address this question. Standard nonlinear mixed model software such as SAS NLMIXED cannot handle this problem. We found that taking a Bayesian approach, and using MCMC, resolved the computational issues and doing so enabled us to provide a realistic distribution estimate for the HEI-2005 total score. While our computation and thinking in solving this problem was Bayesian, we relied on the well-known close relationship between Bayesian posterior means and maximum likelihood, the latter not computationally feasible, and thus were able to develop standard errors using balanced repeated replication, a survey-sampling approach.

    OBJECTIVE To determine whether consumption of a single dental treat with specific mechanical properties and active ingredients would provide a 24-hour effect on dental plaque bacteria and halitosis in dogs. ANIMALS 10 dogs of various breeds from a privately owned colony that had received routine dental scaling and polishing 4 weeks before the study began. PROCEDURES Dogs were randomly assigned to receive 1 placebo or dental treat first. A 4-week washout period was provided, and then dogs received the opposite treatment. Oral plaque and breath samples were collected before and 0.5, 3, 12, and 24 hours after treat consumption. Volatile sulfur compounds (VSCs) concentration was measured in breath samples. Total aerobic, total anaerobic, Porphyromonas gulae, Prevotella intermedia-like, Tannerella forsythia, and Fusobacterium nucleatum bacterial counts (measured via bacterial culture) and total live bacterial counts, total live and dead bacterial counts, and bacterial vitality (measured via quantitative real-time PCR assay) were assessed in plaque samples. RESULTS Compared with placebo treat consumption, dental treat consumption resulted in a significant decrease in breath VSCs concentration and all plaque bacterial counts, without an effect on bacterial vitality. Effects of the dental treat versus the placebo treat persisted for 12 hours for several bacterial counts and for 24 hours for breath VSCs concentration. CONCLUSIONS AND CLINICAL RELEVANCE Although clinical benefits should be investigated in larger scale, longer-term studies, results of this study suggested that feeding the evaluated dental treat may help to decrease oral bacterial growth in dogs for 12 hours and oral malodor for 24 hours. A feeding interval of 12 hours is therefore recommended. PMID:27227499

  9. HOW RELIABLE IS 24 HOUR SERUM LITHIUM LEVEL AFTER A TEST DOSE OF LITHIUM IN PREDICTING OPTIMAL LITHIUM DOSE?

    1989-01-01

    SUMMARY 57% of a group of 35 patients treated with Lithium Carbonate at dosages predicted by the nomogram suggested by Cooper et al (1973) failed to reach therapeutic levels of serum lithium. This finding casts serious doubts on the usefulness of the claim by Cooper et al (1973 & 1976) that 24 hour serum lithium level after a test dose of 600 mg. lithium can predict the daily lithium dose.

  13. Flow cytometric comparison of platelets from a whole blood and finger-prick sample: impact of 24 hours storage.

    Swanepoel, Albe C; Stander, Andre; Pretorius, Etheresia

    2013-03-01

    In this study, we investigate the validity and laboratory utility of flow cytometry when analyzing platelet activation by studying CD41, CD42b, CD62P and CD63. We compare flow cytometry results from citrated whole-blood and finger-prick samples directly after collection and also after storing both a finger-prick and whole-blood sample for 24 hours. Citrated whole-blood and finger-prick samples were taken from three healthy individuals on two occasions, and a total of 60,000 cells were analyzed for each of the four phycoerythrin-labeled monoclonal antibodies. Half of each sample was analyzed immediately after sampling while the other half was kept in the fridge at 6 °C for 24 hours before analysis. No significant difference was found between the sampling methods or the period of time before analysis. Results therefore suggest that an appropriately prepared finger-prick sample can be used for platelet function analysis, and samples can be stored for 24 hours in the fridge at 6 °C before analysis.

  14. [Exercise tolerance in angina patients 3 and 24 hours after administration of a new delayed-action preparation of metoprolol].

    Giusti, C; Verdecchia, P; Pentimone, F; Regoli, F; Cordoni, M; Bongini, A M

    1981-01-01

    To assess the duration of improved exercise tolerance by metoprolol given in a new sustained-release formulation, 40 in-patients affected by stable exercise-induced angina pectoris received single-blind placebo in day 1 and thereafter, in double-blind cross-over once daily administration, metoprolol RETARD 100 mg and 200 mg in days 3 and 5. Symptom-limited cycloergometric exercise tests were performed at 3 and 24 hours after placebo and after each of the two doses of metoprolol RETARD. Duration of exercise, maximal workload and total work performed did significantly increase at 3 and 24 hours after metoprolol RETARD 100 mg (P less than 0.01) and 200 mg (P less than 0.01), without any significant difference between the two doses. Peak systolic arterial pressure and heart rate were lowered by metoprolol RETARD 200 mg at 3 (P less than 0.01) and 24 (P less than 0.01) hours, whereas only the peak heart rate at 3 hours was lowered (P less than 0.05) by the 100 mg dose. It is concluded that in patients with stable exercise-induced angina pectoris, metoprolol RETARD 200 mg appears to be able to increase exercise tolerance and to reduce exercise-induced myocardial oxygen consumption throughout 24 hours period. This may justify a once daily dosing schedule of the 200 mg dose, aimed at improving patient compliance. PMID:7343379

  15. Relationship of 24-hour ambulatory blood pressure and heart rate with markers of hepatic function in cirrhotic patients

    Stergiou George S

    2010-12-01

    Full Text Available Abstract Background There is evidence that in cirrhotic patients, certain hemodynamic parameters, such as blood pressure and heart rate, are related to the severity of liver disease. This study investigated whether non-invasive 24-hour ambulatory blood pressure and heart rate are more closely associated with markers of liver disease severity than conventional office measurements. Methods Ambulatory patients with cirrhosis underwent office blood pressure and heart rate measurements, 24-hour ambulatory blood pressure monitoring and blood laboratory tests. Results Fifty-one patients (32 men, mean age 57.4 ± 11.3 years completed the study. Twenty six patients had compensated liver cirrhosis (group A and 25 patients had more advanced liver disease (group B. Group A and B patients differed significantly both in ambulatory asleep diastolic blood pressure (p Conclusions Heart rate seems to be a more reliable marker of ongoing liver dysfunction than blood pressure. Evaluation of blood pressure and heart rate with 24-hour ambulatory measurement does not seem to offer more information than conventional office measurements.

  16. Albuminuria Assessed From First-Morning-Void Urine Samples Versus 24-Hour Urine Collections as a Predictor of Cardiovascular Morbidity and Mortality

    2008-01-01

    Screening for albuminuria has been advocated because it is associated with cardiovascular morbidity and all-cause mortality. The "gold standard" to assess albuminuria is 24-hour urinary albumin excretion (UAE). Because 24-hour urine collection is cumbersome, guidelines suggest measuring albuminuria

    Fractional anisotropy (FA) is an effective marker of motor outcome at the chronic stage of stroke yet proves to be less efficient at early time points. This study aims to determine which diffusion metric in which location is the best marker of long-term stroke outcome after thrombolysis with diffusion tensor imaging (DTI) at 24 hours post-stroke. Twenty-eight thrombolyzed patients underwent DTI at 24 hours post-stroke onset. Ipsilesional and contralesional FA, mean (MD), axial (AD), and radial (RD) diffusivities values were calculated in different Regions-of-Interest (ROIs): (1) the white matter underlying the precentral gyrus (M1), (2) the corona radiata (CoRad), (3) the posterior limb of the internal capsule (PLIC) and (4) the cerebral peduncles (CP). NIHSS scores were acquired at admission, day 1, and day 7; modified Rankin Scores (mRS) at 3 months. Significant decreases were found in FA, MD, and AD of the ipsilesional CoRad and M1. MD and AD were also significantly lower in the PLIC. The ratio of ipsi and contralesional AD of the CoRad (CoRad-rAD) was the strongest diffusion parameter correlated with motor NIHSS scores on day 7 and with the mRS at 3 months. A Receiver-Operator Curve analysis yielded a model for the CoRad-rAD to predict good outcome based on upper limb NIHSS motor scores and mRS with high specificity and sensitivity. FA values were not correlated with clinical outcome. In conclusion, axial diffusivity of the CoRad from clinical DTI at 24 hours post-stroke is the most appropriate diffusion metric for quantifying stroke damage to predict outcome, suggesting the importance of early axonal damage.

    Background Genetic factors can influence antihypertensive response to metoprolol, and many studies focused on the relationship between the genotype in β1-adrenergic receptor and blood pressure (BP), little was known about the association of angiotensin-converting enzyme (ACE) genotype with the therapeutic result of metoprolol. The present study aimed to investigate whether the ACE gene insertion (I) / deletion (D) polymorphism Is related to the response to metoprolol in Chinese Han hypertensive patients.Methods Ninety-six patients with essential hypertension received metoprolol (100 mg once daily) as monotherapy for 8 weeks. Twenty-four hours ambulatory blood pressure monitoring and dynamic electrocardiogram were performed before and after treatment. Genotyping analysis was performed using PCR. The association of the ACE gene I/D polymorphism with variations in BP and heart rate (HR) was observed after the 8-week treatment.Results The patients with ACE gene II polymorphism showed greater reduction in 24-hour average HR than those with ID or DD polymorphisms (P=0.045), no effect of this genotype on the reduction in seating HR or in BP was observed. After adjusting for age, gender, body mass index, BP and HR at baseline, the ACE gene I/D polymorphism was still an independent predictor for variations in 24-hour average HR.Conclusions The II polymorphism in ACE gene could be a candidate predictor for greater reduction in 24-hour average HR in Chinese Han hypertensive patients treated by metoprolol. Greater benefits would be obtained by patients with II polymorphism from the treatment with metoprolol. Larger studies are warranted to validate this finding.

A Receiver-Operator Curve analysis yielded a model for the CoRad-rAD to predict good outcome based on upper limb NIHSS motor scores and mRS with high specificity and sensitivity. FA values were not correlated with clinical outcome. In conclusion, axial diffusivity of the CoRad from clinical DTI at 24 hours post-stroke is the most appropriate diffusion metric for quantifying stroke damage to predict outcome, suggesting the importance of early axonal damage.

    Fractional anisotropy (FA) is an effective marker of motor outcome at the chronic stage of stroke yet proves to be less efficient at early time points. This study aims to determine which diffusion metric in which location is the best marker of long-term stroke outcome after thrombolysis with diffusion tensor imaging (DTI) at 24 hours post-stroke. Twenty-eight thrombolyzed patients underwent DTI at 24 hours post-stroke onset. Ipsilesional and contralesional FA, mean (MD), axial (AD), and radial (RD) diffusivities values were calculated in different Regions-of-Interest (ROIs): (1) the white matter underlying the precentral gyrus (M1), (2) the corona radiata (CoRad), (3) the posterior limb of the internal capsule (PLIC) and (4) the cerebral peduncles (CP). NIHSS scores were acquired at admission, day 1, and day 7; modified Rankin Scores (mRS) at 3 months. Significant decreases were found in FA, MD, and AD of the ipsilesional CoRad and M1. MD and AD were also significantly lower in the PLIC. The ratio of ipsi and contralesional AD of the CoRad (CoRad-rAD) was the strongest diffusion parameter correlated with motor NIHSS scores on day 7 and with the mRS at 3 months. A Receiver-Operator Curve analysis yielded a model for the CoRad-rAD to predict good outcome based on upper limb NIHSS motor scores and mRS with high specificity and sensitivity. FA values were not correlated with clinical outcome.

    Full Text Available Abstract Background Limited data is available on sodium (Na and potassium (K intake in young children estimated by 24 hour (24h excretion in urine. The aim was to assess 24h urinary excretion of Na and K in six-year-old children and its relationship with diet quality. Methods The study population was a subsample of a national dietary survey, including six-year-old children living in the greater Reykjavik area (n=76. Three day weighed food records were used to estimate diet quality. Diet quality was defined as adherence to the Icelandic food based dietary guidelines. Na and K excretion was analyzed from 24h urine collections. PABA check was used to validate completeness of urine collections. The associations between Na and K excretion and diet quality were estimated by linear regression, adjusting for gender and energy intake. Results Valid urine collections and diet registrations were provided by 58 children. Na and K excretion was, mean (SD, 1.64 (0.54 g Na/24h (approx. 4.1 g salt/24h and 1.22 (0.43 g K/24h. In covariate adjusted models Na excretion decreased by 0.16 g Na/24h (95% CI: 0.31, 0.06 per 1-unit increase in diet quality score (score range: 1–4 while K excretion was increased by 0.18 g K/24h (95% CI: 0.06, 0.29. Conclusions Na intake, estimated by 24h urinary excretion was on average higher than recommended. Increased diet quality was associated with lower Na excretion and higher K excretion in six-year-old children.

    Full Text Available Abstract The aim of this work is to identify major food sources and dietary constituents of Senegalese adults. We conducted a cross-sectional study, using a single 24-hour dietary recall interview. Foods were classified into food groups based on similarities in nutrient content or use. Food groups included foods consumed individually, or as part of food mixtures such as stews, soups, or sandwiches. Median consumption (amount/day of each food was determined and examined by relevant subgroups. Participants were 50 healthy Senegalese men, aged 20-62 years recruited at the Hôpital Général de Grand Yoff in Dakar, Senegal and from Sendou village, a rural area outside Dakar. A total of 90 foods and beverages were identified and classified into 11 groups. Sixty-five percent of foods identified could be classified as meats, grains, or fruits/vegetables. Fruits and vegetables comprised 42% (38/90 of all foods; meats 12% (11/90; and grains 11% (10/90. Sauces (6%, 5/90, sweets (4%, 4/90, and desserts (4%, 4/90 were also reported. The most common fruits/vegetables reported were potato, carrot, mango, and lettuce; commonly reported grains were bread and rice; and commonly reported meats were fish, beef, and ox. There were no differences in reported daily intake of each food by age, ethnicity, education, or residence. Most foods reported were traditional to the Senegalese diet, despite the increasing availability of Western foods in Senegal.

  5. Dietary pattern and its association with the prevalence of obesity and related cardiometabolic risk factors among Chinese children.

    Xianwen Shang

    Full Text Available BACKGROUND: The association of dietary pattern with chronic diseases has been investigated widely in western countries. However, information is quite limited among children in China. Our study is aimed to identify the dietary patterns of Chinese children and examine their association with obesity and related cardiometabolic risk factors. METHODS: A total of 5267 children were selected using multistage random sampling from 30 primary schools of 5 provincial capital cities in China. Dietary intake was derived from 24 hour dietary recall for three consecutive days. Anthropometric measurements, glucose and lipid profiles were obtained. Factor analysis combined with cluster analysis was used for identifying major dietary patterns. The associations of dietary patterns with obesity and related cardiometabolic risk factors were examined by logistic regression analysis. RESULTS: Three mutually exclusive dietary patterns were identified, which were labeled as the healthy dietary pattern, the transitive dietary pattern, and the Western dietary pattern. Compared with children of the healthy dietary pattern, the multiple-adjusted odds ratios (95% confidence interval (CI of obesity were 1.11 (0.89-1.38 for children with the transitive dietary pattern and 1.80 (1.15-2.81 for children with the Western dietary pattern, which was 1.31 (95%CI 1.09-1.56 and 1.71 (95%CI: 1.13-2.56, respectively, for abdominal obesity. The Western dietary pattern was associated with significantly higher concentrations of low-density lipoprotein cholesterol (P<.001, triglycerides (P<.001, systolic blood pressure (P = 0.0435 and fasting glucose (P = 0.0082 and a lower concentration of high-density lipoprotein cholesterol (P = 0.0023, as compared with the healthy dietary pattern. CONCLUSIONS: The Western dietary pattern characterized by red meat, eggs, refined grain and products, was positively associated with odds of obesity, the levels of plasma glucose, low-density lipoprotein

    Full Text Available Abstract Background Aim of the study was to assess QTc interval by a 24-hour ECG recording in a group of HIV-infected individuals with a basal prolonged QTc. The risk factors associated with QTc prolongation and the indices of cardiovascular autonomic control were also evaluated. Methods A case–control study was performed using as cases 32 HIV-infected patients with prolonged (>440 msec QTc interval as assessed by Holter ECG, and as controls 64 HIV-infected subjects with normal QTc interval. Autonomic function was evaluated by heart rate variability analysis during 24-hour recording. Results Duration of HIV disease was significantly longer among cases than among controls (p=0.04. Waist/hip ratio was also higher among cases than among controls (p=0.05. Frequency domain analysis showed the absence of physiologic decrease of low frequency (LF in the night period in both cases and controls. The LF night in cases showed a statistically significant reduction when compared with controls (p=0.007. Conclusions In our study group, QTc interval prolongation was associated with a longer duration of HIV infection and with a greater waist/hip ratio. HIV patients with QTc interval prolongation and with a longer duration of HIV infection were more likely to have an impairment of parasympathetic and sympathetic cardiac component.

    Full Text Available ABSTRACTBackground: Thermogenic ingredients may play a role in weight management. In vitro and rodent work suggests that components of black pepper may impact energy expenditure, and in humans, other TPRV1 agonists e.g. capsaicin, augment EE. Objectives: To determine the impact of BP on 24-hour EE, respiratory quotient, and biochemical markers of metabolism and satiety, a randomized, controlled, cross-over study of black pepper (0.5mg/meal versus no pepper control was conducted in post-menopausal women. Subjects spent two 24-hour periods in a whole room indirect calorimeter. Results: Post-meal glucose, insulin, gut peptides and catecholamines were measured. Energy expenditure, respiratory quotient, or biochemical markers assessed did not differ significantly between the black pepper and no pepper control study days. Conclusions: Our findings do not support a role for black pepper in modulating energy expenditure in overweight postmenopausal women. Future work targeting alternative populations, administering black pepper in the fasted state, or in combination with other spices, may reveal the thermogenic effect of this spice.Trial registration: This trial was registered at clinicaltrials.gov (NCT01729143.Key words: Black pepper, piperine, energy expenditure, metabolic chamber

  8. Dietary Pattern Is Associated with Obesity in Older People in China: Data from China Health and Nutrition Survey (CHNS

    Xiaoyue Xu

    2015-09-01

    Full Text Available Background: No studies have been conducted to explore the associations between dietary patterns and obesity among older Chinese people, by considering gender and urbanization level differences. Methods: We analyzed data from the 2009 China Health and Nutrition Survey (2745 individuals, aged ≥ 60 years. Dietary data were obtained using 24 hour-recall over three consecutive days. Height, Body Weight, and Waist Circumference were measured. Exploratory factor analysis was used to identify dietary patterns. Multinomial and Poisson regression models were used to examine the association between dietary patterns and Body Mass Index (BMI status/central obesity. Results: The prevalence of general and central obesity was 9.5% and 53.4%. Traditional dietary pattern (high intake of rice, pork and vegetables was inversely associated with general/central obesity; modern dietary pattern (high intake of fruit, fast food, and processed meat was positively associated with general/central obesity. The highest quartile of traditional dietary pattern had a lower risk of general/central obesity compared with the lowest quartile, while an inverse picture was found for the modern dietary pattern. These associations were consistent by gender and urbanization levels. Conclusions: Dietary patterns are associated with general/central obesity in older Chinese. This study reinforces the importance of a healthy diet in promoting healthy ageing in China.

    Ahmad, Ziad; Khanna, Nitin; Kerr, Deborah A.; Boushey, Carol J.; Delp, Edward J.

    2014-02-01

    Many chronic diseases, including obesity and cancer, are related to diet. Such diseases may be prevented and/or successfully treated by accurately monitoring and assessing food and beverage intakes. Existing dietary assessment methods such as the 24-hour dietary recall and the food frequency questionnaire, are burdensome and not generally accurate. In this paper, we present a user interface for a mobile telephone food record that relies on taking images, using the built-in camera, as the primary method of recording. We describe the design and implementation of this user interface while stressing the solutions we devised to meet the requirements imposed by the image analysis process, yet keeping the user interface easy to use.

  13. The problem of the enhanced specific locus mutation yield in the mouse after 24 hours' dose fractionation

    In irradiation of mouse spermatogonia, split doses with 24 hours between fractions give a higher yield of specific locus mutations than the whole dose given at once, or if the fractions are given many weeks apart. The enhancement of the challenging dose efficiency is 2.5 - 3.1 for a 500 R conditioning exposure and 1.7 for a 100 R conditioning exposure, the calculation being made on the assumption of a linearly decreasing efficiency of the conditioning dose with dose. Roughly, 24 hrs fractionation of a given dose leads to twice as many mutations as would be expected on the basis of extrapolation from lower doses. The mechanism behind the enhancement is still poorly understood. However, the enhancement may mean that under given conditions, genetic damage from radiation may be 2 - 3 times greater than commonly reckoned

    2013-01-01

    Background Although sleep is often associated with waking health behaviors (WHB) such as alcohol consumption, caffeine use, smoking, and exercise, the causal direction of these relationships is unclear. Purpose The present study used time-series data to examine the temporal dynamics of WHB and sleep characteristics in participants of the SWAN Sleep Study. Methods 303 women completed daily assessments of WHB and wore wrist actigraphs to measure sleep characteristics for the duration of the study (Mean=29.42 days, SD=6.71). Results Vector autoregressive modeling revealed that weekly patterns of sleep and WHB best predicted subsequent sleep and WHB, suggesting that the associations between WHB and sleep persist beyond their immediate influence. Some WHB predicted some subsequent sleep characteristics, but sleep did not predict subsequent WHB. Conclusions These novel findings provide insight into the temporal dynamics of 24-hour behaviors and encourage consideration of both sleep and WHB in health promotion and behavior change efforts.

Patients and methods: This retrospective cohort study was approved by the ethical committee of Maharaj Nakorn Chiang Mai Hospital, Thailand. We reviewed the data of 44,339 patients receiving anesthesia for emergency surgery during the period from January 1, 2003 to March 31, 2011. The data included patient characteristics, surgical procedures, American Society of Anesthesiologists (ASA physical status classification, anesthesia information, location of anesthesia performed, and outcomes. Data of patients who had received topical anesthesia or monitoring anesthesia care were excluded. Factors associated with cardiac arrest were identified by univariate analyses. Multiple regressions for the risk ratio (RR and 95% confidence intervals (CI were used to determine the strength of factors associated with cardiac arrest. A forward stepwise algorithm was chosen at a P-value <0.05. Results: The incidence (within 24 hours of perioperative cardiac arrest in patients receiving anesthesia for emergency surgery was 163 per 10,000.

  17. Dietary Intake of Some Essential Micronutrients in China

    2001-01-01

    Objective Based on the data collected in the 1992 national nutrition survey in China, the food consumption and nutrients intake were calculated, and the consumption of some micronutrients was evaluated. Method Dietary data were obtained by using a three days' inventory change plus food weighing in combination with 24 hours recall method for three consecutive days. The food consumption and nutrients intake were calculated in accordance with the Chinese food composition table. The consumption of some micronutrients was evaluated in reference to the Chinese RDAs. Results The average intakes of niacin, ascorbic acid and vitamin E were sufficient, whereas that of zinc, selenium and thiamin were between 80% and 90% RDAs. The consumption of calcium, retinol equivalent and riboflavin was low compared with the Chinese RDAs. Calcium was the most insufficient nutrient in Chinese diet. Conclusion Food fortification seems necessary for improving the nutritional status of some micronutrients in China.

  18. Intracranial Pressure Elevation 24 Hours after Ischemic Stroke in Aged Rats is Prevented by Early, Short Hypothermia Treatment

    Lucy Anne Murtha

    2016-05-01

    Full Text Available Stroke is predominantly a senescent disease, yet most preclinical studies investigate treatment in young animals. We recently demonstrated that short-duration hypothermia-treatment completely prevented the dramatic intracranial pressure (ICP rise seen post-stroke in young rats. Here, our aim was to investigate whether a similar ICP rise occurs in aged rats and to determine whether short-duration hypothermia is an effective treatment in aged animals. Experimental Middle Cerebral Artery occlusion (MCAo - 3 hour occlusion was performed on male Wistar rats aged 19-20 months. At one hour after stroke-onset, rats were randomized to 2.5 hours hypothermia-treatment (32.5 °C or normothermia (37 °C. ICP was monitored at baseline, for 3.5 hours post-occlusion, and at 24 hours post-stroke. Infarct and edema volumes were calculated from histology. Baseline pre-stroke ICP was 11.2 ± 3.3 mmHg across all animals. Twenty-four hours post-stroke, ICP was significantly higher in normothermic animals compared to hypothermia-treated animals (27.4 ± 18.2 mmHg vs. 8.0 ± 5.0 mmHg, p = 0.03. Infarct and edema volumes were not significantly different between groups. These data demonstrate ICP may also increase 24 hours post-stroke in aged rats, and that short-duration hypothermia treatment has a profound and sustained preventative effect. These findings may have important implications for the use of hypothermia in clinical trials of aged stroke patients.

    Full Text Available Gaëtan Guérin, Xavier Bourges, Frédéric Turquier Covidien-Surgical Solutions, Research and Development, Trévoux, France Purpose: Tacks and sutures ensure a strong fixation of meshes, but they can be associated with pain and discomfort. Less invasive methods are now available. Three fixation modalities were compared: the ProGrip™ laparoscopic self-fixating mesh; the fibrin glue Tisseel™ with Bard™ Soft Mesh; and the SorbaFix™ absorbable fixation system with Bard™ Soft Mesh. Materials and methods: Meshes (6 cm ×6 cm were implanted in the preperitoneal space of swine. Samples were explanted 24 hours after surgery. Centered defects were created, and samples (either ten or eleven per fixation type were loaded in a pressure chamber. For each sample, the pressure, the mesh displacement through the defect, and the measurements of the contact area were recorded. Results: At all pressures tested, the ProGrip™ laparoscopic self-fixating mesh both exhibited a significantly lower displacement through the defect and retained a significantly higher percentage of its initial contact area than either the Bard™ Soft Mesh with Tisseel™ system or the Bard™ Soft Mesh with SorbaFix™ absorbable fixation system. Dislocations occurred with the Bard™ Soft Mesh with Tisseel™ system and with the Bard™ Soft Mesh with SorbaFix™ absorbable fixation system at physiological pressure (<225 mmHg. No dislocation was recorded for the ProGrip™ laparoscopic self-fixating mesh. Conclusion: At 24 hours after implantation, the mechanical fixation of the ProGrip™ laparoscopic self-fixating mesh was found to be significantly better than the fixation of the Tisseel™ system or the SorbaFix™ absorbable fixation system.

    Full Text Available Objective: to study the specific features of the daily arterial stiffness (AS profile in men with different phenotypes of chronic obstructive pulmonary disease (COPD concurrent with hypertension. Subjects and methods. The investigation enrolled 78 male patients with COPD and hypertension. The patients were divided according to COPD phenotypes into 2 groups: 1 COPD patients with emphysema; 2 those with bronchitis. The exclusion criteria were less than 40 years and more than 80 years of age; diabetes mellitus; coronary heart disease; vascular diseases; an exacerbation of chronic diseases; bronchial and pulmonary diseases of another etiology. The patients underwent 24-hour blood pressure and AS monitoring, external respiratory function testing: spirography with a short-acting β2-agonist test, a six-minute walk test at baseline and after a hemoglobin oxygen saturation test, and a CAT test. Results. The patients of both groups were observed to have a statistically significant increase in (dP/dtmax as compared to those of the control group (p < 0.05; p < 0.01 in both the daytime and nighttime. In these periods, the COPD patients with emphysema had a higher AIx than those with bronchitis (p < 0.001. There was a statistically significantly (p < 0.001 higher AIx in the nighttime than in the daytime in Groups 1 and 2 patients. Conclusion. The patients with different COPD phenotypes were noted to have impaired arterial elastic properties, circadian AS changes with predominantly nocturnal impaired vascular stiffness. Relationships were found between 24-hour AS values and clinicoanamnestic findings.

  4. Characterization of lymphocyte subsets over a 24-hour period in Pineal-Associated Lymphoid Tissue (PALT in the chicken

    McNulty John A

    2006-01-01

    Full Text Available Abstract Background Homeostatic trafficking of lymphocytes in the brain has important relevance to the understanding of CNS disease processes. The pineal gland of the chicken contains large accumulations of lymphocytes that suggest an important role related to homeostatic circadian neuro-immune interactions. The purpose of this initial study was to characterize the lymphocyte subsets in the pineal gland and quantitate the distribution and frequency of lymphocyte phenotypes at two time points over the 24-hour light:dark cycle. Results PALT comprised approximately 10% of the total pineal area. Image analysis of immunocytochemically stained sections showed that the majority of lymphocytes were CD3+ (80% with the remaining 20% comprising B-cells and monocytes (Bu-1+, which tended to distribute along the periphery of the PALT. T-cell subsets in PALT included CD4+ (75–80%, CD8+ (20–25%, TCRαβ/Vβ1+ (60%, and TCRγδ+ (15%. All of the T-cell phenotypes were commonly found within the interfollicular septa and follicles of the pineal gland. However, the ratios of CD8+/CD4+ and TCRγδ+/TCRαβ/Vβ1+ within the pineal tissue were each 1:1, in contrast to the PALT where the ratios of CD8+/CD4+ and TCRγδ+/TCRαβ/Vβ1+ each approximated 1:4. Bu-1+ cells were only rarely seen in the pineal interstitial spaces, but ramified Bu-1+ microglia/macrophages were common in the pineal follicles. Effects of the 24-h light:dark cycle on these lymphocyte-pineal interactions were suggested by an increase in the area of PALT, a decline in the density of TCRαβ/Vβ1+ cells, and a decline in the area density of Bu-1+ microglia at the light:dark interphase (1900 h compared to the dark:light interphase (0700 h. Conclusion The degree of lymphocyte infiltration in the pineal suggests novel mechanisms of neuro-immune interactions in this part of the brain. Our results further suggest that these interactions have a temporal component related to the 24-hour light

  5. Mean 24-hours sympathetic nervous system activity decreases during head-down tilted bed rest but not during microgravity

    Christensen, Nj; Heer, M.; Ivanova, K.; Norsk, P.

    Sympathetic nervous system activity is closely related to gravitational stress in ground based experiments. Thus a high activity is present in the standing-up position and a very low activity is observed during acute head-out water immersion. Adjustments in sympathetic activity are necessary to maintain a constant blood pressure during variations in venous return. Head-down tilted bed rest is applied as a model to simulate changes observed during microgravity. The aim of the present study was to test the hypothesis that mean 24-hours sympathetic activity was low and similar during space flight and in ground based observation obtained during long-term head-down tilted bed rest. Forearm venous plasma noradrenaline was measured by a radioenzymatic technique as an index of muscle sympathetic activity and thrombocyte noradrenaline and adrenaline were measured as indices of mean 24-hours sympathoadrenal activity. Previous results have indicated that thrombocyte noradrenaline level has a half-time of 2 days. Thus to reflect sympathetic activity during a specific experiment the study period must last for at least 6 days and a sample must be obtained within 12 hours after the experiment has ended. Ten normal healthy subjects were studied before and during a 14 days head-down tilted bed rest as well as during an ambulatory study period of a similar length. The whole experiment was repeated while the subjects were on a low calorie diet. Thrombocyte noradrenaline levels were studied in 4 cosmonauts before and within 12 hours after landing after more than 7 days in flight. Thrombocyte noradrenaline decreased markedly during the head-down tilted bed rest (pnoradrenaline decreased in the adaptation period but not during the intervention. During microgravity thrombocyte noradrenaline increased in four cosmonauts and the percentage changes were significantly different in cosmonauts and in subjects participating in the head down tilted bed rest study (170± 29% (Mean± SEM) vs. 57

    2005-01-01

    Background Hypoxic pulmonary hypertension (HPH) is initiated by inhibition of O2-sensitive, voltage-gated (Kv) channels in pulmonary arterial smooth muscle cells (PASMCs). The mechanism of hypoxic pulmonary hypertension has not yet been fully elucidated. The mitochondrial ATP-sensitive K+ channel (MitoKATP) is extremely sensitive to hypoxia, and is a decisive factor in the control of mitochondrial membrane potential (ΔΨm). This study investigated the changes of cell membrane potential and Kv channel in cultured human pulmonary artery smooth muscle cell (hPASMC) exposed to 24 hour-hypoxia, and explored the role of MitoKATP and ΔΨm in this condition.Results After exposure to diazoxide for 24 hours, the intensity of R-123 fluorescence in normoxic hPASMCs was significantly increased compared with control group (P<0.05), but there were no significant changes in these tests after the hPASMCs had been exposed to 5-HD for 24 hours. Twenty-four hour-hypoxia or 24 hour-hypoxia + diazoxide could markedly increase the intensity of R-123 fluorescence in hPASMC and the changes were more significant in 24 hour-hypoxia +diazoxide group than in 24 hour-hypoxia group (P<0.05) although 5-HD could partly weaken the effect of 24 hour-hypoxia on the intensity of R-123 fluorescence. After exposure to diazoxide for 24 hours, the cell membrane K+ currents and the expression of cell membrane Kv1.5 mRNA and protein in normoxic hPASMCs were significantly decreased compared with control group (P<0.05), but there were no significant changes in these tests after the hPASMCs had been exposed to 5-HD for 24 hours. Also, 24 hour-hypoxia or 24 hour-hypoxia + diazoxide decreased the cell membrane K+ currents and the expression of Kv1.5 mRNA and protein (P<0.05) but the changes were more significant in 24 hour-hypoxia + diazoxide group than in 24 hour-hypoxia group (P<0.05). Again, 5-HD could partly weaken the inhibitory effect of 24 hour-hypoxia on the cell membrane K+ currents and the expression

    2016-07-01

    Full Text Available Identification of patients at increased risk of death due to acute coronary syndrome (ACS can add to risk stratification and guide the next step in the management of those patients. Altered HRV has been associated with adverse outcomes in heart disease, but this has not been established in patients with acute chest pain.This study aimed to create a non-invasive, economical and risk-free method in the clinical evaluation and diagnosis of significant CAD among patients with unstable angina.Twenty-four-hour Holter recordings of 100 patients with ACS were initiated within 24 hours of admission at the emergency department; stress ECG was done for all patients while coronary angiography was done only for patients with abnormal stress test. Time domain, frequency domain, and nonlinear HRV were examined.The mean SDNN was statistically significantly lower in patients with abnormal stress test, many time and frequency domain HRV parameters was statistically lower in patients with significant coronary arteries obstruction. HRV measured close to the ACS onset may assist in risk stratification. HRV parameters may provide additional, incremental prognostic information to established assessment guidelines and possible early intervention in those patients.

    Predicting the thermal load for the next 24 hours is essential for optimal control of heating, ventilating, and air conditioning (HVAC) systems that use thermal cool storage. It can be useful in minimizing costs and energy in nonstorage systems. A cooperative research project between a US. university and a Japanese corporation investigated four generally used prediction methods to examine the basic models with variations and to compare the accuracy of each model. A cooling and heating seasonal data set with known next-day weather was used to evaluate the accuracy of each prediction method. The results indicate that an artificial neural network (ANN) model produces the most accurate thermal load predictions. After the initial comparisons with a computer-generated data set, the ANN model was applied to two measured building loads from another research project. These sets included typical measurement noise related to continuous field monitoring. The predictions of the next-day cooling load using the ANN prediction model were close to the actual data, even when the next-day weather was forecast. This confirms that the ANN model has sufficient accuracy and is the correct method for practical utilization in HVAC system control, thermal storage optimal control, and load/demand management.

    The radio millisecond pulsar J1713+0747 is regarded as one of the highest-precision clocks in the sky, and is regularly timed for the purpose of detecting gravitational waves. The International Pulsar Timing Array collaboration undertook a 24-hour global observation of PSR J1713+0747 in an effort to better quantify sources of timing noise in this pulsar, particularly on intermediate (1 - 24 hr) timescales. We observed the pulsar continuously over 24 hr with the Arecibo, Effelsberg, GMRT, Green Bank, LOFAR, Lovell, Nancay, Parkes, and WSRT radio telescopes. The combined pulse times-of-arrival presented here provide an estimate of what sources of timing noise, excluding DM variations, would be present as compared to an idealized root-N improvement in timing precision, where N is the number of pulses analyzed. In the case of this particular pulsar, we find that intrinsic pulse phase jitter dominates arrival time precision when the S/N of single pulses exceeds unity, as measured using the eight telescopes that ob...

    2002-01-01

    Objectives: To study reproductive health needs of Shanghai people, and to develop appropriate measures to meet their needs.Methods: Statistical analysis of 24 hours reproductive health hotline data 4,000 random sampled sex questions, comparing answers from differen t gender and different questions (sex questions vs other non-sex questions).Results: During the first 9 months a total of 44,216 calls wer e received by medical staff. The callers included various age groups (aged 12-7 8), different marital status, from Shanghai and outside. In total, the numbers o f men and women on hotline calls were almost same. The contents of the hotline c ounseling covered all aspects of reproductive health care; among them, the issue concerning male and female sex problems and prenatal and infant health care con stituted 26.5% and 34% respectively. Men asked questions about sex more frequent ly than women, whereas women asked questions more about baby care. Questions a bout sex problems were asked more often in the late evening until next early mor ning. Conclusions: Shanghai people showed higher needs in sexual heal th care, prenatal care and baby care. When they came across some related problem s or confusions, they would like to receive the professional instant counseling. Relevant health care programmes should be established in order to meet the fer tile-aged public's reproductive health needs.

  12. 24 Hour thallium is superior to nitrate augmented rest MIBI in demonstrating the true extent of myocardial ischemia

    Full text: The aims of this study was to compare 24 hour delayed rest Tl-201 SPECT (24hr Tl) and nitrate-augmented rest Tc-99m MIBI SPECT (GTN-MIBI) in detecting viable ischemic myocardium, and to document the significance of 24hr Tl demonstrated viable myocardium where GTN-MIBI and a stress MIBI pair shows a concordant fixed perfusion defect (FD). Retrospective review of 95 consecutive patients with a FD on a rest GTN-MIBI/stress MIBI SPECT pair who then underwent 24hr Tl. The gold standard was the composite clinical endpoint (CCE) of unstable angina/myocardial infarction/cardiac death in the 6 months following the imaging study, and also the rate of coronary revascularisation. Patients who demonstrated large or moderate extent of 24hr Tl uptake in the FD were considered to have GTN-MIBI underestimated ischemia (n=65); patients who demonstrated small amount or no 24hr Tl uptake in the FD were considered to have no GTN-MIBI underestimated ischemia (n=30). GTN-MIBI underestimates the true amount of myocardial ischemia when compared to 24hr Tl. In patients with a FD on a GTN-MIBI - stress MIBI pair consideration should be given to performing a 24hr Tl in order to unmask underestimated ischemic myocardium. Where such ischemia is unmasked, it is highly clinically important and carries a statistically significant adverse cardiac prognosis.

    Full Text Available Background: The evidence suggests a relationship between lifestyle and diet-related risk factors.Objective: This study assessed the dietary intake and habits of high school girls in Sistan and Bluchistan province, in southeastern Iran.Methods: In a cross-sectional, descriptive study, 753 high school girls aged 14-18 years old wereenrolled by a clustered random sampling method. Dietary intake and food habits were evaluatedby a two-day, 24-hour dietary recall, and a food frequency questionnaire (FFQ.Results: The analysis of dietary intakes showed that energy, calcium, zinc, vitamin C and folate intake, compared to the Dietary Reference Intake (DRI, were found to be lower. The, infrequent intake of milk and dairy products, fruits and vegetables, and a high consumption of empty calorie foods e.g. salty snacks, sweets, soft drinks and junk foods were seen among adolescents.Conclusions: The adolescent girls had an improper dietary intake and food habits. Thus, the implementation of nutrition education programs in schools and the designing of proper patternstowards healthier food choices could help improve eating behaviors, the health maintenance of adolescents, and also prevent diet- related diseases in adulthood.

  14. Estimates of Dietary Sodium Consumption in Patients With Chronic Heart Failure.

    Colin-Ramirez, Eloisa; Arcand, JoAnne; Ezekowitz, Justin A

    2015-12-01

    Estimating dietary sodium intake is a key component of dietary assessment in the clinical setting of HF to effectively implement appropriate dietary interventions for sodium reduction and monitor adherence to the dietary treatment. In a research setting, assessment of sodium intake is crucial to an essential methodology to evaluate outcomes after a dietary or behavioral intervention. Current available sodium intake assessment methods include 24-hour urine collection, spot urine collections, multiple day food records, food recalls, and food frequency questionnaires. However, these methods have inherent limitations that make assessment of sodium intake challenging, and the utility of traditional methods may be questionable for estimating sodium intake in patients with HF. Thus, there are remaining questions about how to best assess dietary sodium intake in this patient population, and there is a need to identify a reliable method to assess and monitor sodium intake in the research and clinical setting of HF. This paper provides a comprehensive review of the current methods for sodium intake assessment, addresses the challenges for its accurate evaluation, and highlights the relevance of applying the highest-quality measurement methods in the research setting to minimize the risk of biased data.

  15. Determination of the 24-hours survival of stored red cells beyond the legal duration (42 and 49 days). Value of a double labelling

    Red cell double labelling using chromium 51 and Tc 99m proved to be the good method for the measurement of 24-hour post-transfusion survival values of red cells stored at 40C. Satisfactory results were obtained with the preservative solution PAGGSS (Phosphate Adenine Guanosine Glucose Sorbitol Saline) for 42 and 49 days, and with ADSOL (Adenine Dextrose Saline Mannital) for 42 days. But for 49 days ADSOL does not maintain 24-hour post-transfusion survival of the cells at an acceptable level, 70 per cent, for this length of time

    Purpose Severe acute pancreatitis (AP) is still a significant clinical problem which is associated with a highly mortality. The aim of this study was the evaluation of prognostic value of CT regional perfusion measurement performed on the first day of onset of symptoms of AP, in assessing the risk of developing severe form of acute pancreatitis. Material and Methods 79 patients with clinical symptoms and biochemical criteria indicative of acute pancreatitis (acute upper abdominal pain, elevated levels of serum amylase and lipase) underwent perfusion CT within 24 hours after onset of symptoms. The follow-up examinations were performed after 4–6 days to detect progression of the disease. Perfusion parameters were compared in 41 people who developed severe form of AP (pancreatic and/or peripancreatic tissue necrosis) with parameters in 38 consecutive patients in whom course of AP was mild. Blood flow, blood volume, mean transit time and permeability surface area product were calculated in the three anatomic pancreatic subdivisions (head, body and tail). At the same time the patient's clinical status was assessed by APACHE II score and laboratory parameters such as CRP, serum lipase and amylase, AST, ALT, GGT, ALP and bilirubin were compared. Results Statistical differences in the perfusion parameters between the group of patients with mild and severe AP were shown. Blood flow, blood volume and mean transit time were significantly lower and permeability surface area product was significantly higher in patients who develop severe acute pancreatitis and presence of pancreatic and/or peripancreatic necrosis due to pancreatic ischemia. There were no statistically significant differences between the two groups in terms of evaluated on admission severity of pancreatitis assessed using APACHE II score and laboratory tests. Conclusions CT perfusion is a very useful indicator for prediction and selection patients in early stages of acute pancreatitis who are at risk of

  18. A 24-hour temporal profile of in vivo brain and heart pet imaging reveals a nocturnal peak in brain 18F-fluorodeoxyglucose uptake.

    Daan R van der Veen

    Full Text Available Using positron emission tomography, we measured in vivo uptake of (18F-fluorodeoxyglucose (FDG in the brain and heart of C57Bl/6 mice at intervals across a 24-hour light-dark cycle. Our data describe a significant, high amplitude rhythm in FDG uptake throughout the whole brain, peaking at the mid-dark phase of the light-dark cycle, which is the active phase for nocturnal mice. Under these conditions, heart FDG uptake did not vary with time of day, but did show biological variation throughout the 24-hour period for measurements within the same mice. FDG uptake was scanned at different times of day within an individual mouse, and also compared to different times of day between individuals, showing both biological and technical reproducibility of the 24-hour pattern in FDG uptake. Regional analysis of brain FDG uptake revealed especially high amplitude rhythms in the olfactory bulb and cortex, while low amplitude rhythms were observed in the amygdala, brain stem and hypothalamus. Low amplitude 24-hour rhythms in regional FDG uptake may be due to multiple rhythms with different phases in a single brain structure, quenching some of the amplitude. Our data show that the whole brain exhibits significant, high amplitude daily variation in glucose uptake in living mice. Reports applying the 2-deoxy-D[(14C]-glucose method for the quantitative determination of the rates of local cerebral glucose utilization indicate only a small number of brain regions exhibiting a day versus night variation in glucose utilization. In contrast, our data show 24-hour patterns in glucose uptake in most of the brain regions examined, including several regions that do not show a difference in glucose utilization. Our data also emphasizes a methodological requirement of controlling for the time of day of scanning FDG uptake in the brain in both clinical and pre-clinical settings, and suggests waveform normalization of FDG measurements at different times of the day.

    2008-01-01

    For school breakfast each day, many elementary schools offer a choice between a cold option that includes ready-to-eat (RTE) cereal and a hot option that includes a non-RTE-cereal entrée such as waffles. For breakfast reports, intrusions (reports of uneaten items) in correctly reported and misreported breakfast options were examined using data from five dietary-reporting validation studies. In each study, fourth-grade children were observed eating school breakfast and school lunch and then in...

  20. Recall Searching with and without Recall

    Neugebauer, Tibor; DiCagno, D.; Sadrieh, A.; Rodriguez Palermo, C.

    2014-01-01

    We revisit the sequential search problem by Hey (1987). In a 2x2 factorial design, varying fixed and random cost treatments with and without recall, we address open research questions that were originally stated by Hey (1987). Our results provide clear evidence for Hey’s (1987) conjecture that recall negatively affects performance in sequential search. With experience, however, search behaviour with and without recall converges towards the optimal reservation rule. We further find that the ut...

    Breum, L; Astrup, A; Andersen, T;

    1990-01-01

    In order to investigate the effect of long-term treatment with dexfenfluramine (dF) on 24-hour energy expenditure (EE), 10 obese females were studied in a double-blind design. Shortly before and 4 weeks after cessation of a 13 months treatment period with either dF (30 mg/day) or placebo (PL) the...... C and at a humidity between 3 and 11 g/m3. Discontinuation of dF treatment did not change energy expenditure significantly from placebo, neither when expressed in kJ/kg lean body mass nor in kJ/kg body weight. After cessation of treatment total 24-hour EE decreased likewise nonsignificantly by 2...... differences. The conclusion is therefore that dF possesses no significant thermogenic effect during long-term administration in human obese subjects....

    Posttraumatic stress disorder (PTSD) is associated with an increased risk of cardiovascular disease and several other chronic illnesses. Alterations in the sympathetic nervous system (SNS) and the hypothalamic-pituitary-adrenal (HPA) axis in PTSD might contribute to these associations but findings regarding SNS and HPA activity in PTSD are heterogeneous.

    2015-12-01

    Full Text Available The aim of the investigation was to assess the potential of cluster analysis as an additional method of data analysis for 24-hour blood pressure monitoring (BPM in patients with both normal geometry and with various types and extents of remodeling of the left ventricle (LV. Materials and Methods. The investigation included 71 patients, ranging in age from 23 to 71. The inclusion criterion was significant arterial hypertension (AH, while exclusion criteria were symptomatic AH and severe co-morbidity. Body mass, height, waist measurement, body mass index, lipid profile, and glycemic level were determined for each subject in addition to carrying out echocardiography and conventional and cluster analysis of 24-hour BPM data of each. Results. In patient groups with different types of left ventricular hypertrophy (LVH, the conventional analysis demonstrated differences in the standard 24-hour BPM parameters. Development of concentric LVH is associated with the highest average day-time and average night-time blood pressure, pressure-induced loads and blood pressure variability. Eccentric LVH has a pathogenetic link to other factors and is formed under conditions of relatively low blood pressure. The use of cluster analysis allowed to reveal the increased occurrence of systolic-diastolic AH in concentric LVH, and isolated systolic AH and isolated diastolic AH in eccentric LVH. Conclusion. Such an integrated approach to the interpretation of 24-hour BPM results, comprising both conventional and cluster analysis, allows for objectification of the study results and reveals the significant features of AH in patients with different types of LV remodeling.

  8. Perceptions of food availability and self-reported dietary intake in urban Costa Rican women: A Pilot Study

    Traci A. Bekelman

    2016-02-01

    Full Text Available Background: Food availability and dietary intake are thought to contribute to rising obesity among women of low socioeconomic status in Latin America. In Costa Rica, few studies have investigated food availability, dietary intake, or how they vary by SES. Objectives: The purpose of this study in San José, Costa Rica was to (1 evaluate women’s perceptions of food availability and, (2 describe dietary intake in women from low- and high-SES areas of the city. Methods: Thirty non-pregnant, non-lactating women between 25 and 50 years were recruited in March 2013 from a low- and high-SES canton. Structured, qualitative interviews assessed perceptions of food availability in 17 of the 30 women. Quantitative 24-hour dietary recalls assessed dietary intake in all 30 women. Results: Many women from the low-SES canton reported that they would include more chicken and fish in their diet if cost were not a barrier. Protein intake as a proportion of total energy intake was significantly greater in women from the high- versus low-SES canton (17% SD=5 vs. 13 SD=3, p = 0.02. Protein intake from animal source foods was significantly greater in women from the high-SES canton (38 g SD=22 vs. 21 SD=11, p = 0.02. Conclusion: Protein intake was greater in high-SES women and this may be due to the perceived cost of animal source foods.

  9. Predictors for Reporting of Dietary Assessment Methods in Food-based Randomized Controlled Trials over a Ten-year Period.

    Probst, Yasmine; Zammit, Gail

    2016-09-01

    The importance of monitoring dietary intake within a randomized controlled trial becomes vital to justification of the study outcomes when the study is food-based. A systematic literature review was conducted to determine how dietary assessment methods used to monitor dietary intake are reported and whether assisted technologies are used in conducting such assessments. OVID and ScienceDirect databases 2000-2010 were searched for food-based, parallel, randomized controlled trials conducted with humans using the search terms "clinical trial," "diet$ intervention" AND "diet$ assessment," "diet$ method$," "intake," "diet history," "food record," "food frequency questionnaire," "FFQ," "food diary," "24-hour recall." A total of 1364 abstracts were reviewed and 243 studies identified. The size of the study and country of origin appear to be the two most common predictors of reporting both the dietary assessment method and details of the form of assessment.

    To evaluate the effectiveness of an additional transdermal fentanyl patch compared to intravenous analgesics in pain control during the 24-hour period following uterine artery embolization (UAE) for myoma and adenomyosis. Between September 2009 and August 2010, 42 patients underwent UAE for myoma or adenomyosis. Of these, 21 received an intravenous opioid (pethidine) and a nonsteroidal anti-inflammatory drug (group A), and 21 received an additional transdermal fentanyl patch (group B). Pain perception levels were established verbally on a 0-10 scale during the 24-hour period following UAE. Differences in pain trends, mean dose of intravenous pethidine, and adverse effects were compared between the two groups. Pain perception was most severe at 6 hours after UAE and the mean pain level of group B at that time was 6.3 {+-} 0.7, which was significantly lower than that of group A, 8.2 {+-} 0.7 (p<0.05). The mean dose of intravenous pethidine was 114.3 {+-} 59.5 mg in group A and 90.5 {+-} 49.0 mg in group B, while the incidence of nausea was 67% in group A and 77% in group B. In both cases, the differences were not significantly different (p>0.05), and no evidence of respiratory distress was demonstrated. The addition of a transdermal fentanyl patch to intravenous analgesics is effective in reducing post-embolization pain during the 24-hour period after UAE.

    Full Text Available Abstract Background The combination of inhaled corticosteroids (ICS and long-acting β2-agonists (LABA is recommended by treatment guidelines for the treatment of persistent asthma. Two such combination products, salmeterol/fluticasone propionate (SFC, Seretide™ GSK, UK and formoterol/budesonide (FBC, Symbicort™, AstraZeneca, UK are commercially available. Objectives The purpose of these studies was to evaluate and compare the duration of bronchodilation of both combination products up to 24 hours after a single dose. Methods Two randomised, double blind, placebo-controlled, crossover studies were performed. Study A was conducted in 33 asthmatic adults receiving 400–1200 mcg of budesonide or equivalent. Serial forced expiratory volume in one second (FEV1 was measured over 24 hours to determine the duration of effect of both SFC (50/100 mcg and FBC (4.5/160 mcg. Study B was conducted in 75 asthmatic adults receiving 800–1200 mcg of budesonide or equivalent and comprised a 4 week run-in of 400 mcg bd Becotide™ followed by 4 weeks treatment with either SFC 50/100 mcg bd or FBC 4.5/160 mcg bd taken in a cross-over manner. Serial 24-hour FEV1 was measured after the first dose and the last dose after each 4-weeks treatment period to determine the offset of action of each treatment. Results In study A, a single inhalation of SFC and FBC produced a sustained bronchodilation at 16 hours with an adjusted mean increase in FEV1 from pre-dose of 0.22 L (95% CI 0.19, 0.35 L for SFC and 0.25 L (95% CI 0.21, 0.37 L for FBC, which was significantly greater than placebo for both treatments (-0.05 L; p 1 from 2–24 hours post dose was -16.0 ml/hr for SFC and -14.2 ml/hr for FBC. The weighted mean AUC over 24 hours was 0.21 Lxmin and 0.22 Lxmin and mean change from pre-dose FEV1 at 12 hours was 0.21 L for SFC and 0.20 L for FBC respectively Conclusion Both SFC and FBC produced a similar sustained bronchodilator effect which was prolonged beyond 12 hours

    2004-03-01

    Full Text Available Abstract Background In most western countries 20% of adults have hypertension. Reports in the literature suggest that from 31 to 86% of treated patients are not at recommended target levels. However it is important to consider how we are determining whether targets are unmet and the degree to which they are unmet. Our underlying hypothesis is that white coat effect is partially responsible for the reported low rates of control of hypertension by primary care practitioners. Methods The study population consists of 1142 patients who are being assessed for enrolment in two community-based randomized controlled trials. Patients must have essential hypertension, be on antihypertensive medication, and must not have met their blood pressure targets. We are reporting on the proportion of patients who have not achieved target, and the degree to which they have not achieved their target. We also report on the mean daytime blood pressures on 24 hour ABPM and compare these to mean blood pressures found on the patients' charts. Results We identified 3284 patient charts of patients with hypertension. Of these, 1142 were determined to be "out of control" (did not achieve target and 436 agreed to undergo 24 hour ABPM for final determination of eligibility. Overwhelmingly (95.8% of the time it was the systolic blood pressure that was not under control. However, most of the patients who had not achieved target according to our criteria were within 10 mmHg of the recommended targets. Isolated systolic blood pressure was the best predictor of elevated mean daytime blood pressure on 24 hour ABPM. Conclusions At least 35% of patients had not achieved target blood pressure levels and this is primarily due to lack of control of systolic blood pressure. The best predictor of continuing hypertension on 24 hour ABPM was the mean systolic blood pressure on the patients chart. However, only 69% of patients who were uncontrolled according blood pressures recorded in the

    Full Text Available Understanding nutrient intake of anorexia nervosa (AN patients is essential for the treatment. Therefore, estimates of total energy and nutrient consumption were made in a group of young women (19 to 30 years with restricting and binge purge subtypes of AN participating in an ecological momentary assessment study. Participants completed three nonconsecutive 24-hour diet recalls. Mean nutrient intakes were stratified by subtype and by quartiles of energy intake and compared to the age specific Dietary Reference Intake (DRI levels, as well as to the reported intakes from the What We Eat In America (WWEIA dietary survey 2011–2012. Reported intake was determined for energy, macronutrients, and micronutrients. The mean body mass index (BMI for all participants was 17.2 ± 0.1 kg/m2. Reported nutrient intake was insufficient for participants in quartiles 1–3 of both AN subtypes when compared to the DRIs. Intake reported by participants in quartile 4 of both subgroups met requirements for most nutrients and even met or exceeded estimated energy needs. Counseling of AN patients should be directed to total food consumption to improve energy intake and to reduce individual nutritional gaps.

  15. Dietary adequacies among South African adults in rural KwaZulu-Natal.

    Fariba Kolahdooz

    Full Text Available BACKGROUND: Food quality, determined by micronutrient content, is a stronger determinant of nutritional status than food quantity. Health concerns resulting from the co-existence of over-nutrition and under-nutrition in low income populations in South Africa have been fully recognized in the last two decades. This study aimed to further investigate dietary adequacy amongst adults in rural KwaZulu-Natal, by determining daily energy and nutrient intakes, and identifying the degree of satisfaction of dietary requirements. METHODS: Cross-sectional study assessing dietary adequacy from 24-hour dietary recalls of randomly selected 136 adults in Empangeni, KwaZulu-Natal, South Africa. RESULTS: Results are presented for men (n = 52 and women (n = 84 19-50 and >50 years old. Mean energy intake was greatest in women >50 years (2852 kcal/day and exceeded Dietary Reference Intake's for both men and women, regardless of age. Mean daily energy intake from carbohydrates was 69% for men and 67% for women, above the Dietary Reference Intake range of 45-65%. Sodium was also consumed in excess, and the Dietary Reference Intakes of vitamins A, B12, C, D, and E, calcium, zinc and pantothenic acid were not met by the majority of the population. CONCLUSION: Despite mandatory fortification of staple South African foods, micronutrient inadequacies are evident among adults in rural South African communities. Given the excess caloric intake and the rising prevalence of obesity and other non-communicable diseases in South Africa, a focus on diet quality may be a more effective approach to influence micronutrient status than a focus on diet quantity.

  16. No association of skin-fold thicknesses and training with race performance in male ultra-endurance runners in a 24-hour run

    2011-01-01

    In male high-level long-distance runners over 10,000 m, a positive association between both the front thigh and medial calf skin-fold thickness and running performance has been demonstrated. It is assumed that the thickness of skin-folds of the lower limb is related to training in highly trained runners. We investigated in 22 male ultra-endurance runners in a 24-hour run the relationship between skin-fold thicknesses and race performance. The 22 runners achieved a total of 154 (47) km during ...

  17. Transient prolonged stunning by dipyridamole stress proved by post-stress (1 hour) and 24 hour Tc-99m-MIBI gated SPECT

    We performed 1st day Tc-99m-sestamibi gated SPECT with dipyridamole/rest Tl-201 SPECT and 2nd day 24 hour delay Tl-201 SPECT/rest Tc-99m-sestamibi gated SPECT in 27 patients with coronary artery disease (24) or having chest pain(3). Stress and rest Tc-99m-sestamibi gated SPECT was acquired at 60min post-injection. A 4-point scoring system (0 to 3 for normal to absent tracer uptake) for 17 segments was used. Wall motion was scored on another 4 point scale (0 to 3 for normal to dyskinesia) in the 1st day post-stress gated and the 2nd day rest gated SPECT. Post-stress gated SPECT showed wall motion abnormality in 94 segments (20%). Fifty-five segments among these 94 showed the same wall motion between post-stress and rest gated SPECT : i.e. 1-1 : 23 segment, 2-2 : 29 segments, 3-3 : 3 segments. Remaining 39 segments (41.5%) showed different wall motion between post-stress and rest Tc-99m-sestamibi gated SPECT. Twenty one segments with wall motion abnormality had normal perfusion (rest : 15 segments, 24 hour delay : 6 segments) at either rest or 24 hour delay. Fifteen among these 21 segments showed persistent post-stress and the 2nd day rest wall motion abnormality (persistent stunning). However, in 6 segments with prolonged (1 hour after stress) stunning, abnormal wall motion did improve in the 2nd day rest Tc-99m-sestamibi gated SPECT (transient prolonged stunning). These 6 segments had normal perfusion at rest (n=4) or at 24 hour delay (n=2). Post stress wall motions showed significantly higher scores in persistent stunning than in prolonged transient stunning (P value<0.05). It was concluded that we could find stunned myocardium with gated Tc-99m-sestamibi SPECT at either post-stress or rest and that some myocardial walls of post-stress 1 hour gated SPECT did not show truly rest wall motion. So, we should be cautious if we use post-stress Tc-99m-sestamibi wall motion to asses rest wall motion

    Full Text Available Purpose: Intake of energy and some nutrients is frequently inadequate in dialysis patients because of eating and appetite disorders due to uremic syndrome. Inadequate energy and protein intake cause to malnutrition. Anthropometric measurements, biochemical markers and dietary intake records have great importance in determining the nutritional status of hemodialysis (HD patients. Therefore this study was planned to determination of daily energy, nutrient intake and some biochemical markers of adult hemodialysis patients. Method and Material:  A hundred and thirty six (male = 73, female = 63 clinically stable HD patients were enrolled in this study. All patients were taken 24-hour dietary recall. The daily energy and nutrient intakes of patients were calculated by food consumption records and anthropometric measurements were taken. Results: The mean age was found 45.5±13.51 years. The ratio of patients with body mass index (BMI below 18.5 kg/m2 was 7.4% and 25 kg/m2 or upper was 16.9%. Blood hemoglobin, hematocrit, albumin and total protein levels were below the normal levels. The daily dietary energy and protein intakes were found under the recommended level in the study period. A significant positive correlation was found between daily protein intake and serum albumin levels (r=0.210, p=0.014, daily protein intake and serum total protein levels (r=0.201, p=0.019, daily energy intake and serum total protein levels (r=0.178, p=0.039. Conclusions: HD patients often have low protein and energy intakes and most of them suffer from malnutrition. Therefore nutritional status of patients should be evaluated and periodically nutrition education should be given for improving eating habits and increasing dietary compliance is recommended.

    Dietary and lifestyle changes in Mexico have been linked to an increase in chronic diseases such as obesity and cardiovascular disease. Important dietary changes such as an increase in the consumption of energy-dense foods (high in oils, animal or processed fats, and sugars) have been recently reported. The objective of this study was to identify how key dietary energy sources correlated with other indexes of cardiovascular disease in a Mexican school-age population. From 2004 to 2006, a convenience sample (n=228) of 9- to 13-year-olds, 48.2% girls and 51.8% boys, from three public urban schools were included. Anthropometric, blood pressure, and dietary assessment (two multiple pass 24-hour recalls) were done. More than half of children did not meet the fruit and vegetable recommended intake. High-fat dairy foods (14% of total energy intake), refined carbohydrates (13.5%), red/processed meat (8.5%), added sugars/desserts (7%), corn tortilla (6.5%), and soft drinks/sweetened beverages (5%) were the highest dietary energy sources consumed. In a subgroup of children (n=185), a fasting blood sample was collected for biochemical analysis. A positive association was observed between glucose and diastolic blood pressure with the intake of soft drinks/sweetened beverages, insulin concentrations and the intake of white bread, and triglyceride concentrations with the intake of added fats. Unhealthful dietary energy sources are frequently consumed by these children. Culturally competent nutrition counseling should be offered to Mexican-American children and their families with a significant risk of cardiovascular disease. Efforts should be made to design and implement nutrition education and health promotion strategies in schools. PMID:20102853

  7. Estimate of the time-zero lung burden of depleted uranium in Gulf War veterans by the 24 hour urinary excretion and exponential decay analysis

    Aim: Significant presence of depleted uranium (DU) in the urine of British, Canadian, and United States veterans nine years after inhalational exposure in the Desert Storm conflict has been reported in the studies of DU urine analysis by mass spectrometry. The aim of this study is to report an estimate of the amount of DU in the respiratory system at the time of exposure from the quantitative current rate of daily excretion. Materials and Methods: Mass spectrometry (TIMS) analysis of 24-hour urinary excretion of the isotopes of DU in five positive (238U/235U > 191.00) and six negative (238U/235U o*e-bt). Substituting the half-life equation into the decay equation relates the initial DU concentration to the rate of excretion, total time, and an unknown decay constant (No = (dN/dt)*ebt/b). A minimum value for the biological half-life of ceramic DU oxide in the lungs was derived from the Batelle report of minimum dissolution time in simulated interstitial lung fluid corresponding to 3.85 years. The concentration of DU at time zero can also be determined by finding the minimum value of the function (No (dN/dt)*ebt/b) with respect to the biological half-life constant, thus estimating DU concentration at the time of exposure. Results: The average depleted uranium concentration was 3.27 x 10-5 mg / 24 hours in DU positive veterans and 1.80 x 10-8 in DU negative veterans. By the use of the Batelle report of the dissolution rate of ceramic uranium oxide in simulated interstitial lung fluid, the estimated lung burden was 0.336 mg in the DU positive and 0.0002 mg in the DU negative veterans. The absolute minimum concentration was 0.294 mg in the positive and 0.0002 in the DU negative veterans. Conclusion: Our work provides a model of estimating the minimum pulmonary concentration of DU at time zero by utilizing gravimetric and mass spectrometric data of the DU isotopes in 24-hour urinary samples and theoretical model of DU dissolution time in simulated interstitial lung fluid

    2011-06-01

    Full Text Available Abstract Background Obesity is increasing in Bahrain and there is lack of information on the energy and macronutrient intake of children. The objective of this research was to study the energy and macronutrient intake as well as food frequency pattern of Bahraini school children. Methods This is a cross-sectional descriptive study conducted on Bahraini school boys and girls aged 6-18 years from all the 11 populated regions of the country. Data on food intake consisted of a 24-hour dietary recall and was obtained by interviewing a sub-sample of the study population. Information was also obtained through a self-administered questionnaire for the entire sample on the weekly frequency of food items that were grouped into 7 categories based on similarity of nutrient profiles. Dietary analysis was performed using the Nutritionist 5 (First Data Bank Version 1.6 1998. Results While the average energy intake of students was close to the Estimated Average Requirements of the UK Reference standards, protein intake substantially exceeded the Reference Nutrient Intake values as did daily sugar consumption. Dietary fiber fell short of the Dietary Recommended Values (UK and 36%-50% students exceeded the Energy % limits for total fat, saturated fat and cholesterol. The Polyunsaturated: Saturated fat ratio remained at an unacceptable level of 0.6 for girls and boys. While sweets, snacks and regular soda drinks were popular, milk, fruits and vegetables were not commonly consumed. Conclusions High sugar consumption, low intake of dietary fiber and high energy % of saturated fat and dietary cholesterol by many Bahraini children, is likely to increase their risk of obesity and cardiovascular diseases in later life. Nutrition education programs in schools should emphasize the importance of healthy balanced diets for growth and health maintenance of children as well as dietary prevention of diseases.

    2012-01-01

    Full Text Available Aims: The aim was to assess the dietary pattern during Ramadan season among type 2 diabetic Muslim subjects who underwent fasting and intensive dietary counseling. Materials and Methods: The study was conducted among 70 Muslim subjects with type 2 diabetes mellitus who undertook fasting during Ramadan and was part of a randomized control trial using pioglitazone published previously. All subjects were subjected to a dietary assessment and counseling at three stages, i.e., initiation of the study, mid-Ramadan and post-Ramadan, by a trained dietician. Dietary assessment was done by the 24-hour dietary recall method and the food frequency questionnaire. Diabetic diet sheets were dispensed to subjects based on their body mass index (BMI, daily activity, and needs. Results: The mean caloric intake between pre-Ramadan (before fasting and mid-Ramadan (15 days after fasting were 1506.80 kcal and 1614.29 (P = 0.001 respectively. The distribution of active components pre and during Ramadan were: carbohydrates (g 260.76 and 265.35 g (P = 0.001, proteins (g 43.64 and 46.19 (P = 0.001 and fat (g was 32.88 and 44.16 (P = 0.0001 respectively. The percentage of energy from dietary carbohydrate prior to fasting (64.11 ± 6.73 and during fasting (68.41 ± 4.41 remained almost unchanged but statistically significant when compared at different intervals before and during fasting. Fat intake increased significantly during fasting (P = < 0.001. Conclusions: The dietary composition in a type 2 diabetic Muslim population who undertook fasting during Ramadan showed a mean increase in consumption of all components of diet during the period of fasting. Nutritional compliance during such a time seems to be difficult and warrants repeated counseling and regular follow-up to achieve targets.

Study Design: A cross-sectional comparative study carried out in Nuclear Medical Centre from Aug 2009 to Jan 2010 at Armed Forces Institute of Pathology (AFIP), Rawalpindi, Pakistan. Patients and Methods: A total of eighty three subjects were enrolled, who were divided into three groups; group 1 comprised 31 normotensive diabetics, group 2 had 37 hypertensive diabetics while group 3 had 15 normal subjects. The DTPA GFR and creatinine clearance in healthy subjects as well as diabetic patients were compared using the unpaired student's t-test. The linear association between GFR, creatinine clearance and disease duration was expressed by Pearson's correlation coefficient 'r' along with their significance levels. Results: Gates GFR showed hyperfiltration in normotensive diabetics (96.6 +- 3.3 ml/min/1.73 m/sub 2/), significantly (p<0.05) higher than controls (85.5 +- 5 ml/min/1.73 m/sub 2/), whereas hypertensive diabetics had a significantly lower (p<0.05) Gates GFR (76.8 +- 3.7) than that of controls. Significant degree of correlation existed between GGFR and CRCL in hypertensive diabetics (p<0.05, r=0.716) and controls (r=0.546). Gates GFR also showed good correlation with duration of diabetes in both diabetic groups as compared to that of CRCL. GGFR also correlated well with duration of hypertension 0.37 (0.31-0.43) as compared to CRCL 0.155 (0.15-0.16) in all groups. Conclusions: The 99mTc-DTPA clearance correlates significantly with 24-hour creatinine clearance as well as with disease duration and can provide a simple and convenient index of kidney function in patients of early diabetic nephropathy.

    1993-01-01

    In three experiments, categorized lists and both free recall and cued recall tests were used to examine hypermnesia. In Experiment 1, materials were drawn from obvious and nonobvious categories in an attempt to vary the amount of relational processing at encoding. The study materials in Experiment 2 consisted of a long word list that comprised several exemplars from each of a number of common categories. In Experiment 3, a single exemplar was drawn from each of 45 categories. In each experiment, similar magnitudes of hypermnesia were obtained on free and cued recall tests. Examination of the specific items recalled across tests indicated that similar processes underlie the hypermnesic effect for both test conditions. Implications of the results for extant accounts of the hypermnesic effect are discussed. It is concluded that the dynamics of retrieval processes change in a systematic fashion across repeated tests and the retention interval following study and that an adequate account of the nature of these changes in retrieval dynamics is essential to our understanding of hypermnesia and related phenomena.

    2016-01-01

    This study aimed to estimate dietary intake of micronutrients among adults in a city in Southern Brazil according to sex and age, and to measure the prevalence of inadequate dietary micronutrient intake according to sex. This is a cross-sectional, population-based study with 1,222 adults 22 to 63 years of age living in Florianópolis, Santa Catarina State, Brazil. Data on dietary intake were obtained from two 24-hour recalls (one in the total sample and the other in a subsample of 40% of the research subjects). Micronutrient intake and prevalence rates for inadequate intake were estimated according to the guidelines of the National Research Council and Institute of Medicine. High prevalence rates of inadequate intake in the entire sample were seen for vitamins A, C, D, and E (range, 52%-100%). Calcium and iron intake were more inadequate in women (87.3% and 13.7%, respectively), as was zinc in men (25.1%). Adults in Florianópolis, showed high prevalence rates of inadequate intake of essential micronutrients. PMID:27580235

    Full Text Available Rapid changes in Thailand’s nutrition and lifestyles have led to increasing diet-related pathologies among people with sedentary occupations. This study examines the extent to which the dietary intake of nutrients and energy by a sample of Thai sedentary workers conforms to the Thai Dietary Reference Intakes (Thai DRIs. The nutrients and energy intake estimates were based on self-reported information collected with a single 24-hour dietary recall and nonweighed 2-day food record. The study participants were Thai adults aged 20–50 years employed in sedentary occupations. A convenience sample of 215 healthy individuals (75 males and 140 females was based on four randomly selected worksites in the Bangkok metropolitan area. For male participants, the study found a median energy intake of 1,485 kcal/day, with 54.4% of energy coming from carbohydrate, 15.9% from protein, and 29.6% from fat. Females’ median energy intake was 1,428 kcal/day, 56% of which came from carbohydrate, 16.2% from protein, and 28.6% from fat. Both genders showed insufficient intake of fiber and most micronutrients. This study provides the material for preventive public health interventions focusing on nutrition-related diseases affecting Thailand’s rapidly growing sedentary workforce.

    2014-11-01

    Full Text Available Dietary intake of cadmium, lead and nickel was determined among students from three universities in Lublin to assess the levels of exposure to these contaminants compared to PTWI and TDI values. The study was performed in 2006–2010 and involved 850 daily food rations of students from the south–east region of Poland. The technique of 24-hour dietary recall and diet duplicates was used. Cadmium, lead and nickel complexes with ammonium-pyrrolidindithiocarbamate were formed and extracted to the organic phase with 4-methylpentan-2-one – MIBK in which their content was measured by flame atomic absorption spectrometry. The highest intake of the elements studied was observed in 2008. The data show that in none of the cases, the level of intake reached 70 % of PTWI/TDI values and thus the risk of developing diseases related to high exposure to these toxic metals absorbed from foodstuffs was low. The parameters of methods were checked during determinations by adding standard solutions to the samples before mineralization and by using two reference materials: Total diet ARC/CL HDP and Bovine muscle RM NIST 8414. The dietary exposure to lead and cadmium has significantly decreased in recent years whereas the exposures to nickel remain on stable levels.

  16. 24-hour urine sodium and potassium excretion in six-year-old children and their parents. Association to diet quality and blood pressure

    Oddný Kristín Kristbjörnsdóttir 1986

    2012-01-01

    Background and aims: Twenty-four hour (24h) excretion of sodium (Na) and potassium (K) in urine are considered to be the golden standard for dietary intake of these substances. The main dietary sources of K are components of many food based dietary guidelines (FBDG) but the main sources of Na are considered less healthy. Studies in adults have shown increased Na and decreased K excretion in urine to be associated with higher blood pressure but less is known about the association in children. ...

    2013-12-01

    Full Text Available Background: Temporal trends in dietary patterns reveal associations between food consumption and increased prevalence of non-communicable chronic diseases. Objectives: This study characterized dietary patterns in adolescents in urban area located in northeast of Brazil, relating it to the markers of a healthy diet. Methods: A cross-sectional study used two 24-hour recalls to assess dietary intake in 430 public school students from Natal-RN, Brazil. Principal component analysis was used to derive dietary patterns according to consumption of food based on weight (grams, energy (Kcal, or fiber (grams. These models resulted in a number of different main components, 7, 8 and 4, respectively (cumulative variance >70%; factor loadings >0.4. The association between independent variables and the factor scores of all components obtained was determined by the Prevalence Ratio (CI 95%. Results: The dietary patterns derived were: (1 Pure Traditional Food System, the highly representative pattern in young adolescents and the first component of the analytical models, (2 Combined and Risk Food System; extraction of total food weight and energy revealed markers of unhealthy diets based on high sugar, saturated fat, and salt consumption, and (3 Modified Traditional Food System represented by fiber; pattern 1 was observed within this model too. The associations observed, predominantly from the TFSm pattern, distinguished by sex, age and nutritional status. Conclusions: Patterns 1 and 3 are characterized by preserved regional food practices that prevent chronic disease, whereas pattern 2 is characterized by health risks. These inter-sectorial findings should be considered in the development of health care policies for children and adolescents.

    2014-12-01

    Full Text Available Adequate quality and quantity of athletes’ competition day diet is critically important for better performance and optimum recovery. The aim of this study was to evaluate the adequacy of nutrient intake and dietary practices of Sri Lankan national volleyball players during a day of a major competition. Dietary practices of 76 athletes (43 males and 33 females were surveyed using 24-hour dietary recall method. Energy and macronutrient intakes were quantitatively assessed in relation to competition using a computerized nutrition analysis software and local food database. Questionnaire was used to examine supplement intake and fluid intake strategies. The results were compared with current nutrition recommendations for these athletes. Mean daily energy intakes were 2309+365 kcal (30.9+5.7 kcal.kg-1.body weight in male and 1829+383 kcal (30.8+6.8 kcal.kg-1.body weight in female athletes. These intake values were 31% and 18% lower than recommended daily energy intake for active Sri Lankan male and female adults, respectively. Daily carbohydrate and protein intakes of all athletes were 5.6+1.0 g.kg-1.day-1 and 0.91+0.37 g.kg-1.day-1, respectively, lower than the recommendations. Total energy, carbohydrate, and protein intake of female athletes were significantly lower than those of males (p<0.05. Frequency of snack intake and calorie content of snacks and main meals in the pre-competition period was sub-optimal. Nutrient intake and dietary practices of national level volleyball players during competition days are sub-optimal and do not meet the current nutrition recommendations. According to the results, it is recommended that athletes use nutrition counselling and strategies for optimizing dietary practices during the competition days.

  2. Metabolic Engineering of Light and Dark Biochemical Pathways in Wild-Type and Mutant Strains of Synechocystis PCC 6803 for Maximal, 24-Hour Production of Hydrogen Gas

    Ely, Roger L.; Chaplen, Frank W.R.

    2014-03-11

    This project used the cyanobacterial species Synechocystis PCC 6803 to pursue two lines of inquiry, with each line addressing one of the two main factors affecting hydrogen (H2) production in Synechocystis PCC 6803: NADPH availability and O2 sensitivity. H2 production in Synechocystis PCC 6803 requires a very high NADPH:NADP+ ratio, that is, the NADP pool must be highly reduced, which can be problematic because several metabolic pathways potentially can act to raise or lower NADPH levels. Also, though the [NiFe]-hydrogenase in PCC 6803 is constitutively expressed, it is reversibly inactivated at very low O2 concentrations. Largely because of this O2 sensitivity and the requirement for high NADPH levels, a major portion of overall H2 production occurs under anoxic conditions in the dark, supported by breakdown of glycogen or other organic substrates accumulated during photosynthesis. Also, other factors, such as N or S limitation, pH changes, presence of other substances, or deletion of particular respiratory components, can affect light or dark H2 production. Therefore, in the first line of inquiry, under a number of culture conditions with wild type (WT) Synechocystis PCC 6803 cells and a mutant with impaired type I NADPH-dehydrogenase (NDH-1) function, we used H2 production profiling and metabolic flux analysis, with and without specific inhibitors, to examine systematically the pathways involved in light and dark H2 production. Results from this work provided rational bases for metabolic engineering to maximize photobiological H2 production on a 24-hour basis. In the second line of inquiry, we used site-directed mutagenesis to create mutants with hydrogenase enzymes exhibiting greater O2 tolerance. The research addressed the following four tasks: 1. Evaluate the effects of various culture conditions (N, S, or P limitation; light/dark; pH; exogenous organic carbon) on H2 production profiles of WT cells and an NDH-1 mutant; 2. Conduct metabolic flux analyses for

  3. Recollective and Nonrecollective Recall

    Brainerd, C. J.; Reyna, V. F.

    2010-01-01

    The study of recollective and nonrecollective retrieval has become controversial, owing to several critiques of traditional recognition-based measurement (e.g., remember/know, ROC, process dissociation). We present a new methodology in which subjects merely study and recall lists, using any standard paradigm (associative, cued, free, or serial recall), the data are analyzed with a Markov model whose parameters measure recollective and nonrecollective retrieval, and the model’s fit is compared...

    It has not hitherto been clarified whether there is an association between dietary behavior and circadian variation in autonomic nervous system activity among shift workers. This study examines diurnal 24-h rhythm in heart rate variability (HRV) and dietary behavior among rotating shift workers, while taking into account the sleep-wake cycle and physical activity. The subjects were 11 female and 2 male nurses or caregivers working in a rotating 2-shift system at a health care facility. All th...

  6. Behavioral contexts, food-choice coping strategies, and dietary quality of a multiethnic sample of employed parents.

    2011-03-01

    Employed parents' work and family conditions provide behavioral contexts for their food choices. Relationships between employed parents' food-choice coping strategies, behavioral contexts, and dietary quality were evaluated. Data on work and family conditions, sociodemographic characteristics, eating behavior, and dietary intake from two 24-hour dietary recalls were collected in a random sample cross-sectional pilot telephone survey in the fall of 2006. Black, white, and Latino employed mothers (n=25) and fathers (n=25) were recruited from a low/moderate income urban area in upstate New York. Hierarchical cluster analysis (Ward's method) identified three clusters of parents differing in use of food-choice coping strategies (ie, Individualized Eating, Missing Meals, and Home Cooking). Cluster sociodemographic, work, and family characteristics were compared using χ(2) and Fisher's exact tests. Cluster differences in dietary quality (Healthy Eating Index 2005) were analyzed using analysis of variance. Clusters differed significantly (P≤0.05) on food-choice coping strategies, dietary quality, and behavioral contexts (ie, work schedule, marital status, partner's employment, and number of children). Individualized Eating and Missing Meals clusters were characterized by nonstandard work hours, having a working partner, single parenthood and with family meals away from home, grabbing quick food instead of a meal, using convenience entrées at home, and missing meals or individualized eating. The Home Cooking cluster included considerably more married fathers with nonemployed spouses and more home-cooked family meals. Food-choice coping strategies affecting dietary quality reflect parents' work and family conditions. Nutritional guidance and family policy needs to consider these important behavioral contexts for family nutrition and health. PMID:21338739

  7. Dietary adherence and acceptability of five different diets, including vegan and vegetarian diets, for weight loss: The New DIETs study.

    Moore, Wendy J; McGrievy, Michael E; Turner-McGrievy, Gabrielle M

    2015-12-01

    The goal of the present study was to examine dietary adherence and acceptability among participants from the New DIETs study who were randomized to one of four plant-based diets (vegan, vegetarian, pesco-vegetarian, semi-vegetarian) or an omnivore diet. Primary outcomes at two- and six months included dietary adherence (24-hour dietary recalls), weight loss and changes in animal product intake (mg cholesterol) by adherence status, Three-Factor Eating Questionnaire (TFEQ), Power of Food Scale (PFS), dietary acceptability (Food Acceptability Questionnaire), and impact of diet preference on adherence. No differences were found in dietary adherence or changes in FAQ, TFEQ, or PFS among the groups. At six months, non-adherent vegan and vegetarian participants (n=16) had a significantly greater decrease in cholesterol intake (-190.2 ± 199.2 mg) than non-adherent pesco-vegetarian/semi-vegetarian (n=15, -2.3 ± 200.3 mg, P=0.02) or omnivore participants (n=7, 17.0 ± 36.0, P=0.04). Non-adherent vegan/vegetarian participants lost significantly more weight at six months (-6.0 ± 6.7%) than non-adherent omnivore participants (-0.4 ± 0.6%, P=0.04). Dietary preference had no impact on adherence at six months. Due to equal rates of adherence and acceptability among the diet groups, instructing participants to follow vegan or vegetarian diets may have a greater impact on weight loss and animal product intake than providing instruction in more moderate approaches even among non-adherent participants.

    1993-08-01

    The effect of ranitidine and cisapride on acid reflux and oesophageal motility was investigated in 18 patients with endoscopically verified erosive reflux oesophagitis. Each patient was treated with placebo, ranitidine (150 mg twice daily), and ranitidine (150 mg twice daily) plus cisapride (20 mg twice daily) in a double blind, double dummy, within subject, three way cross over design. Oesophageal acidity and motility were monitored under ambulatory conditions for 24 hours on the fourth day of treatment, after a wash out period of 10 days during which patients received only antacids for relief of symptoms. Acid reflux was monitored by a pH electrode located 5 cm above the lower oesophageal sphincter. Intraoesophageal pressure was simultaneously recorded from four transducers placed 20, 15, 10, and 5 cm above the lower oesophageal sphincter. Upright reflux was three times higher than supine reflux (median (range) 13.3 (3.7-35.0)% v 3.7 (0-37.6)% of the time with pH upright reflux (p conventional dose of ranitidine (150 mg twice daily) can be improved to more than 60% by combination with cisapride (20 mg twice daily). The cisapride induced increase in oesophageal contractile force and propagation velocity seems to enhance the clearance of gastro-oesophageal reflux. Combination of a histamine H2 receptor antagonist with a prokinetic agent may therefore provide an alternative treatment for reflux oesophagitis. PMID:8174947

    Carina eFueller; Jens eLoescher; Peter eIndefrey

    2013-01-01

    In list learning paradigms with free recall, written recall has been found to be less susceptible to intrusions of related concepts than spoken recall when the list items had been visually presented. This effect has been ascribed to the use of stored orthographic representations from the study phase during written recall (Kellogg, 2001). In other memory retrieval paradigms, by contrast, either better recall for modality-congruent items or an input-independent writing superiority effect have b...

    This study investigates the effects of differing time limits and the level of language proficiency on the written recalls of 66 Japanese EFL undergraduates. Results showed that different time limits affected total recall, but not main ideas recalled. Regardless of proficiency level, the 20-minute group (Group 2) recalled a greater number of idea units than the 8-minute group (Group 1). However, no significant difference was found between Groups 1 and 2 regarding the recall of main ideas, alth...

  12. "2001: A Space Odyssey" Revisited: The Feasibility of 24 Hour Commuter Flights to the Moon Using NTR Propulsion with LUNOX Afterburners. Revised

    Borowski, Stanley K.; Dudzinski, Leonard A.

    2001-01-01

    The prospects for "24 hour" commuter flights to the Moon. similar to that portrayed in 2001: A Space Odyssey but on a more Spartan scale. are examined using two near term. "high leverage" technologies-liquid oxygen (LOX)-augmented nuclear thermal rocket (NTR) propulsion and "lunar-derived" oxygen (LUNOX) production. Iron-rich volcanic glass. or "orange soil," discovered during the Apollo 17 mission to Taurus-Littrow. has produced a 4% oxygen yield in recent NASA experiments using hydrogen reduction. LUNOX development and utilization would eliminate the need to transport oxygen supplies from Earth and is expected to dramatically reduce the size, cost and complexity of space transportation systems. The LOX-augmented NTR concept (LANTR) exploits the high performance capability of the conventional liquid hydrogen (LH2)-cooled NTR and the mission leverage provided by LUNOX in a unique way. LANTR utilizes the large divergent section of its nozzle as an "afterburner" into which oxygen is injected and supersonically combusted with nuclear preheated hydrogen emerging from the engine's choked sonic throat-essentially "scramjet propulsion in reverse." By varying the oxygen-to-hydrogen mixture ratio, the LANTR engine can operate over a wide range of thrust and specific impulse (Isp) values while the reactor core power level remains relatively constant. The thrust augmentation feature of LANTR means that "big engine" performance can be obtained using smaller. more affordable. easier to test NTR engines. The use of high-density LOX in place of low-density LH2 also reduces hydrogen mass and tank volume resulting in smaller space vehicles. An implementation strategy and evolutionary lunar mission architecture is outlined which requires only Shuttle C or "in-line" Shuttle-derived launch vehicles, and utilizes conventional NTR-powered lunar transfer vehicles (LTVs), operating in an "expendable mode" initially, to maximize delivered surface payload on each mission.

  15. Taking Advantage of the Strengths of 2 Different Dietary Assessment Instruments to Improve Intake Estimates for Nutritional Epidemiology

    Carroll, R. J.

    2012-01-24

    With the advent of Internet-based 24-hour recall (24HR) instruments, it is now possible to envision their use in cohort studies investigating the relation between nutrition and disease. Understanding that all dietary assessment instruments are subject to measurement errors and correcting for them under the assumption that the 24HR is unbiased for usual intake, here the authors simultaneously address precision, power, and sample size under the following 3 conditions: 1) 1-12 24HRs; 2) a single calibrated food frequency questionnaire (FFQ); and 3) a combination of 24HR and FFQ data. Using data from the Eating at America\\'s Table Study (1997-1998), the authors found that 4-6 administrations of the 24HR is optimal for most nutrients and food groups and that combined use of multiple 24HR and FFQ data sometimes provides data superior to use of either method alone, especially for foods that are not regularly consumed. For all food groups but the most rarely consumed, use of 2-4 recalls alone, with or without additional FFQ data, was superior to use of FFQ data alone. Thus, if self-administered automated 24HRs are to be used in cohort studies, 4-6 administrations of the 24HR should be considered along with administration of an FFQ.

  16. Reproducibility and Validity of a Food Frequency Questionnaire for Assessing Dietary Consumption via the Dietary Pattern Method in a Chinese Rural Population.

    Xudong Liu

    Full Text Available This study was conducted to assess the reproducibility and validity of a food frequency questionnaire (FFQ that was developed to assess the overall dietary consumption via dietary pattern method in a rural population in southwest China.A total of 179 participants aged between 40 and 70 years old were included in this study. Participants administered FFQ at baseline (FFQ1 and one year later (FFQ2 to assess the reproducibility. Six 3-day 24-hour recalls (24HRs were completed between the administrations of two FFQs to determine the validity. Dietary patterns from three separate dietary sources were derived by using principle component factor analysis. Comparisons between dietary pattern scores were made by using Pearson or intraclass correlation coefficient, cross-classification analysis, weighted kappa (κ statistic and Bland-Altman analysis. The de-attenuated method was adopted to correct the monthly and seasonally variation and the partial correlation analysis was used correct the influence by total energy intake.Two major dietary factors, labeled as prudent pattern and processed food pattern, were identified. The prudent pattern was characterized by higher factor loadings of wheat, rice, fresh vegetables, bean products, nuts, red meat, white meat and fresh eggs; and the processed food pattern was characterized by higher factor loadings of pickled vegetables, preserved vegetables and salted meat. Between Two FFQs, intraclass correlation coefficients were 0.57 for prudent pattern and 0.55 for processed food pattern, partial Pearson correlation coefficients were 0.51 for the prudent pattern and 0.56 for the processed food pattern; weighted κ statistic ranged from 0.45 (for the prudent pattern to 0.56 (for the processed food pattern. Between FFQs and 24HRs, de-attenuated correlation coefficients ranged from 0.54 to 0.78 for the prudent pattern and from 0.55 to 0.61 for the processed food pattern; partial Pearson correlation coefficients ranged

    Hispanic adults who had low literacy in English (n = 14.3) and who attended community college English-as-a-Second-Language (ESL) classes, completed 24-hour dietary recalls using version 2.5 of the computerized Minnesota Nutrition Data System (NDS), which included many Hispanic foods. The purposes of our study were to assess the appropriateness of NDS for a Hispanic group who had low literacy in English, to describe the development and implementation of training procedures for NDS interviewers, and to discuss the special problems that occurred using the enhanced version of NDS. Further, nutrient, intakes for the study population, as calculated using NDS, were compared with nutrient estimates from the Hispanic Health and Nutrition Examination Survey (HHANES). Results suggest that version 2.5 of NDS is a useful tool for collecting dietary information for Hispanics who have low literacy in English. Challenges encountered during data collection for this study could be categorized into three types: regional differences in foods, food preparation differences, and lack of appropriate options in NDS for preparation methods. Generally, the study group and HHANES participants had similar intakes, although the study group tended to have a more healthful nutrition profile. Overall, findings indicate that NDS is a promising assessment tool for nutrition practitioners who work with Hispanics who have low literacy in English. Continued improvements to the NDS system can correct its shortcomings related to regional/ cultural food differences. PMID:8948390

    Full Text Available Abstract Background Aging is a process associated with physiological changes such as in body composition, energy expenditure and physical activity. Data on energy and nutrient intake adequacy among elderly is important for disease prevention, health maintenance and program development. Methods This descriptive cross-sectional study was designed to determine the energy requirements and adequacy of energy and nutrient intakes of older persons living in private households in a rural Filipino community. Study participants were generally-healthy, ambulatory, and community living elderly aged 60–100 y (n = 98, 88 of whom provided dietary information in three nonconsecutive 24-hour food-recall interviews. Results There was a decrease in both physical activity and food intake with increasing years. Based on total energy expenditure and controlling for age, gender and socio-economic status, the average energy requirement for near-old (≥ 60 to 2 (p = 0.003 for every 1% decrease in total caloric intake as percentage of the total energy expenditure requirements. Conclusion These community living elderly suffer from lack of both macronutrient intake as compared with energy requirements, and micronutrient intake as compared with the standard dietary recommendations. Their energy intakes are ~65% of the amounts required based on their total energy expenditure. Though their intakes decrease with increasing age, so do their energy expenditure, making their relative insufficiency of food intake stable with age.

  11. Gemcitabine-induced radiation recall

    Purpose: To study and report 6 patients with radiation recall in unique sites, secondary to gemcitabine chemotherapy. Methods and Materials: The clinical presentations and outcomes of 6 patients with radiation recall secondary to gemcitabine chemotherapy were retrospectively analyzed over the course of a 1-year period. Results: Radiation recall reactions were seen in the central nervous system, skin, gastrointestinal tract, and in the lymphatic and musculoskeletal systems. The time between initiation of radiation and recall of the radiation phenomenon ranged from 3 weeks to 8 months from the time gemcitabine was initiated. The usual dosage of gemcitabine in these cases was 1000 mg/m2 given on a weekly basis. No radiation therapy was given concomitantly with gemcitabine. Treatment of the recall reaction consisted of discontinuing gemcitabine and initiating steroid therapy, supportive therapy, and/or nonsteroidal anti-inflammatory agents. Minimal improvement was seen in 3 out of 6 patients, and resolution of the radiation recall was seen in 3 out of 6 patients. A comprehensive review of the literature revealed that radiation recall with gemcitabine has been related to skin reactions only; no previous cases of radiation recall occurring in the central nervous system have been reported with any chemotherapy agent. Conclusion: Radiation recall from gemcitabine chemotherapy is rare, but can potentially arise in any site that has been previously irradiated. Treating physicians must be aware of this potential toxicity from gemcitabine and radiation and discontinue the gemcitabine if radiation recall is observed

    Parental stress is an understudied factor that may compromise parenting practices related to children's dietary intake, physical activity, and obesity. However, studies examining these associations have been subject to methodological limitations, including cross-sectional designs, retrospective measures, a lack of stress biomarkers, and the tendency to overlook momentary etiologic processes occurring within each day. This paper describes the recruitment, data collection, and data analytic protocols for the MATCH (Mothers And Their Children's Health) study, a longitudinal investigation using novel real-time data capture strategies to examine within-day associations of maternal stress with children's physical activity and dietary intake, and how these effects contribute to children's obesity risk. In the MATCH study, 200 mothers and their 8 to 12 year-old children are participating in 6 semi-annual assessment waves across 3 years. At each wave, measures for mother-child dyads include: (a) real-time Ecological Momentary Assessment (EMA) of self-reported daily psychosocial stressors (e.g., work at a job, family demands), feeling stressed, perceived stress, parenting practices, dietary intake, and physical activity with time and location stamps; (b) diurnal salivary cortisol patterns, accelerometer-monitored physical activity, and 24-hour dietary recalls; (c) retrospective questionnaires of sociodemographic, cultural, family, and neighborhood covariates; and (d) height, weight, and waist circumference. Putative within-day and longitudinal effects of maternal stress on children's dietary intake, physical activity, and body composition will be tested through multilevel modeling and latent growth curve models, respectively. The results will inform interventions that help mothers reduce the negative effects of stress on weight-related parenting practices and children's obesity risk. PMID:25987483

  16. Does the usual dietary intake of patients with depression require vitamin-mineral supplementation?

    Stefańska, Ewa

    2014-02-01

    Full Text Available Introduction. Research on diet and nutrition of patients with depression show that their eating habits are frequently irrational and result in the inconsistent supply of nutrients, especially vitamins and minerals, the deficiency of which leads to nervous system dysfunction. Aim. The aim of the study was to evaluate the content of selected vitamins and minerals in daily food rations of patients suffering from recurrent depressive disorders. Methods. The study involved a group of 69 people (54 women and 15 men, aged 18-65 years, mean age of women 45.7 ± 12.2 years, men 46.0 ± 12.2 years, treated for recurrent depressive disorders. A questionnaire designed in the Department of Dietetics and Clinical Nutrition, Medical University of Bialystok was used to collect dietary data. The quantitative assessment of eating habits used a 24-hour diet recall including 3 weekdays and 1 weekend day. Results. The study showed that the supply of most nutrients assessed was inconsistent with recommendations. Conclusions. The results indicate that the need for vitamin-mineral supplementation should be considered individually. Nutritional education related to the proper choice of groups of food products is indicated at the time of clinical improvement to ensure the optimum supply of vitamins and minerals.

    Background: The objective of the current study was to assess the effects of royal jelly supple-mentation on body weight, total daily energy and macronutrients intakes in type2 diabetic fe-males. Methods: In this randomized clinical trial, fifty female volunteers with type2 diabetes were as-signed into the supplemented (n=25) and placebo (n=25) groups, given a daily dose of 1000 mg royal jelly soft gel or placebo, for 8 weeks, respectively. Before and after the intervention, body weight and height of subjects were measured and body mass index was calculated. Dietary intake of patients was assessed using 24-hour food recall questionnaire for three non consecutive days (including 1 weekend day) and analyzed with Nutritionist IV software. The normally distributed data were compared using paired and independent t-tests, where appropriate. Results: Royal jelly supplementation significantly (P<0.01) decreased the mean body weight (72.45±4.42 vs. 71.00±6.44 kg) while it increased insignificantly in placebo group (73.02±6.44 vs 73.52±6.80 kg). Royal jelly supplementation resulted in significant decrease of mean daily total energy (P<0.01) and carbohydrate (P<0.01) intakes, while in placebo group the mean daily total energy and fat intakes were increased significantly (P<0.05). Conclusion: Supplementation with royal jelly may be beneficial in weight management of di-abetic patients. PMID:24688939

    1999-01-01

    This paper considers characterizations of perfect recall in extensive form games. It is shown that perfect recall can be expressed in terms of choices without any reference to infomation sets. When information sets are taken into account, it is decomposable into an ordering of information sets and that players do not forget what they knew nor what they did. Thus, if information sets are partially ordered, then perfect recall is implied by the player's inability to refine her information from ...

    2012-07-01

    Normative values and confidence intervals for the hydration indices of women do not exist. Also, few publications have precisely described the fluid types and volumes that women consume. This investigation computed seven numerical reference categories for widely used hydration biomarkers (eg, serum and urine osmolality) and the dietary fluid preferences of self-reported healthy, active women. Participants (n=32; age 20±1 years; body mass 59.6±8.5 kg; body mass index [calculated as kg/m(2)] 21.1±2.4) were counseled in the methods to record daily food and fluid intake on 2 consecutive days. To reduce day-to-day body water fluctuations, participants were tested only during the placebo phase of the oral contraceptive pill pack. Euhydration was represented by the following ranges: serum osmolality=293 to 294 mOsm/kg; mean 24-hour total fluid intake=2,109 to 2,506 mL/24 hours; mean 24-hour total beverage intake=1,300 to 1,831 mL/24 hours; urine volume=951 to 1,239 mL/24 hours; urine specific gravity=1.016 to 1.020; urine osmolality=549 to 705 mOsm/kg; and urine color=5. However, only 3% of women experienced a urine specific gravity hyperhydration, euhydration, and dehydration that can be used by registered dietitians and clinicians to counsel women about their hydration status.

    This study evaluated the relative validity of the dietary indicators from the questionnaire used in the Brazilian National School-Based Health Survey (PeNSE) in the city of Rio de Janeiro, Brazil. The sample included 174 students. The following indicators were evaluated: regular consumption (≥ 5 times a week) of markers for healthy eating, markers for unhealthy eating, and routine eating habits (having meals with parents or guardians (MEAL), having breakfast (breakfast), and eating while studying or watching TV. The results of the questionnaire were compared with three 24-hour recalls. For all the markers of healthy eating, there was no difference in the proportion of regular consumption when comparing the two methods. The rates detected by the questionnaire were higher for packaged snacks and crackers and lower for cold cuts and MEAL. The indicators for regular consumption of markers for healthy eating and that referring to BREAKFAST were those with the highest accuracy. The dietary indicators used by the PeNSE survey showed satisfactory validity. PMID:24936819

  3. Calibration of the dietary data obtained from the Brazilian center of the Natural History of HPV Infection in Men study: the HIM Study

    2010-12-01

    Full Text Available The objective of this study was to estimate the regressions calibration for the dietary data that were measured using the quantitative food frequency questionnaire (QFFQ in the Natural History of HPV Infection in Men: the HIM Study in Brazil. A sample of 98 individuals from the HIM study answered one QFFQ and three 24-hour recalls (24HR at interviews. The calibration was performed using linear regression analysis in which the 24HR was the dependent variable and the QFFQ was the independent variable. Age, body mass index, physical activity, income and schooling were used as adjustment variables in the models. The geometric means between the 24HR and the calibration-corrected QFFQ were statistically equal. The dispersion graphs between the instruments demonstrate increased correlation after making the correction, although there is greater dispersion of the points with worse explanatory power of the models. Identification of the regressions calibration for the dietary data of the HIM study will make it possible to estimate the effect of the diet on HPV infection, corrected for the measurement error of the QFFQ.

    Full Text Available Background: To examine macronutrient and micronutrient intake of adolescent girls of Tehran, capital of Iran to discover any malnutrition in relation to weight status and dieting.Methods: A cross-sectional study was conducted. Four hundred 11- to 17-year-old students were selected by multistage clus­ter sampling from secondary and high schools of Tehran. The information about dietary intakes was taken by food fre­quency questionnaire and 24-hour recall form. The students' body mass indices (BMIs were measured and were classified ac­cording to National Center for Health Statistics /Center for Disease Control and Prevention (2000 growth charts. Partici­pants were also questioned about body image and dieting. Results: 6.7% of adolescent girls were classified as being obese, 14.6% overweight, 75.4% normal and 3.2% underweight. Stu­dents 11-13 year old, had mean intakes lower than estimated average requirement (EAR for folic acid, vitamin E, cal­cium, magnesium, phosphorus, potassium and sodium, and 14-18 year old students had mean intakes lower than EAR for nia­cin, pyridoxine, folic acid, pantothenic acid, vitamin E, calcium, magnesium, phosphorus, potassium, sodium and zinc. Obese and overweight adolescents had less carbohydrate, thiamin, niacin, iron and selenium intake. The participants, who were dieting, used significantly less amounts of proteins, carbohydrates, thiamin, niacin, iron, selenium, sodium and zinc.Conclusion: Knowing the harmful consequences of nutrient deficiency especially in adolescents, nutrition education must be emphasized in schools to promote nutritional literacy.

  7. Dietary assessment methods in epidemiologic studies

    Shim, Jee-Seon; Oh, Kyungwon; Kim, Hyeon Chang

    2014-01-01

    Diet is a major lifestyle-related risk factor of various chronic diseases. Dietary intake can be assessed by subjective report and objective observation. Subjective assessment is possible using open-ended surveys such as dietary recalls or records, or using closed-ended surveys including food frequency questionnaires. Each method has inherent strengths and limitations. Continued efforts to improve the accuracy of dietary intake assessment and enhance its feasibility in epidemiological studies...

  8. Large individual differences in free recall

    Tarnow, Eugen

    2016-01-01

    Using single factor ANOVA I show that there are large individual differences in free recall ({\\eta} ranges from 0.09-0.26) including the total recall, the balance between recency and primacy, and the initial recall (subsequent recalls show smaller individual differences). All three memory properties are relatively uncorrelated. The variance in the initial position may be a measure of executive control and is correlated with total recall (the smaller the variation, the larger the recall).

  13. Association between previously diagnosed circulatory conditions and a dietary inflammatory index.

    Wirth, Michael D; Shivappa, Nitin; Hurley, Thomas G; Hébert, James R

    2016-03-01

    Inflammation is a key contributor to the development or recurrence of circulatory disorders. Diet is a strong modifier of inflammation. It was hypothesized that more pro-inflammatory diets, as indicated by higher Dietary Inflammatory Index (DII) scores, would be associated with self-reported previously diagnosed circulatory disorders using National Health and Nutrition Examination Survey (NHANES) data. This analysis included NHANES respondents from 2005-2010 (n = 15,693). The DII was calculated from micro and macronutrients derived from a single 24-hour recall. Logistic regression, stratified by sex and adjusted for important covariates, was used to determine the odds of previous circulatory disorder diagnoses by quartile of DII scores. Excluding hypertension, which had a prevalence of 30%, the prevalence of any circulatory disorder was 8%. Those in DII quartile 4 were 1.30 (95%CI = 1.06-1.58) times more likely to have a previous circulatory disorder (excluding hypertension) compared to those in DII quartile 1. Similar findings were observed for specific CVDs including congestive heart failure, stroke, and heart attack. Participants in DII quartile 4 were more likely to have a diagnosis of hypertension compared to those in DII quartile 1 (prevalence odds ratio = 1.19, 95%CI = 1.05-1.34). Results tended to be stronger among females. Individuals with a previous circulatory disorder diagnosis from NHANES appear to have more pro-inflammatory diets compared to those without a previous diagnosis. Because inflammation is an important factor related to recurrence of circulatory disorders, the DII could be used in treatment programs to monitor dietary modulators of inflammation among individuals with these conditions.

  14. Association between Maternal and Child Dietary Diversity: An Analysis of the Ghana Demographic and Health Survey.

    Dickson Abanimi Amugsi

    Full Text Available This study examined the association between maternal and child dietary diversity in a population-based national sample in Ghana.The data for this analysis are from the 2008 Ghana Demographic and Health Survey. We used data obtained from 1187 dyads comprised of mothers' ages 15-49 and their youngest child (ages 6-36 months. Maternal and child dietary diversity scores (DDS were created based on the mother's recall of her own and her child's consumption of 15 food groups, during the 24 hours prior to the in-home survey. The same food groups were used to compose both maternal and child DDS. Linear regression was used to assess the relationship between the predicted outcome--child DDS--and maternal DDS, taking into account child age and sex, maternal factors (age, education, occupation, literacy, empowerment, number of antenatal visits as an indicator of health care use, household Wealth Index, and urban/rural place of residence.There was a statistically significant positive association between child and maternal DDS, after adjusting for all other variables. A difference of one food group in mother's consumption was associated with a difference of 0.72 food groups in the child's food consumption (95% CI: 0.63, 0.82. Also, statistically significant positive associations were observed such that higher child DDS was associated with older child age, and with greater women's empowerment.The results show a significant positive association between child and maternal DD, after accounting for the influence of child, maternal and household level factors. Since the likely path of influence is that maternal DDS impacts child DDS, public health efforts to improve child health may be strengthened by promoting maternal DDS due to its potential for a widened effect on the entire family.

  15. Dietary patterns in Brazilian patients with nonalcoholic fatty liver disease: a cross-sectional study

    Silvia Marinho Ferolla

    2013-01-01

    Full Text Available OBJECTIVE: Recent evidence suggests that non-alcoholic fatty liver disease is associated with diet. Our aim was to investigate the dietary patterns of a Brazilian population with this condition and compare them with the recommended diet. METHODS: A cross-sectional study was conducted on 96 non-alcoholic fatty liver disease patients before any dietetic counseling. All patients underwent abdominal ultrasound, biochemical tests, dietary evaluations, and anthropometric evaluations. Their food intake was assessed by a semi-quantitative food-frequency questionnaire and 24-hour food recall. RESULTS: The median patient age was 53 years, and 77% of the individuals were women. Most (67.7% participants were obese, and a large waist circumference was observed in 80.2% subjects. Almost 70% of the participants had metabolic syndrome, and 62.3% presented evidence of either insulin resistance or overt diabetes. Most patients (51.5, 58.5, and 61.7%, respectively exceeded the recommendations for energy intake, as well as total and saturated fat. All patients consumed less than the amount of recommended monounsaturated fatty acids, and 52.1 and 76.6% of them consumed less polyunsaturated fatty acids and fiber, respectively, than recommended. In most patients, the calcium, sodium, potassium, pyridoxine, and vitamin C intake did not meet the recommendations, and in 10.5-15.5% of individuals, the tolerable upper limit intake for sodium was exceeded. The patients presented a significantly high intake of meats, fats, sugars, legumes (beans, and vegetables and a low consumption of cereals, fruits, and dairy products compared with the recommendations. CONCLUSIONS: Although patients with non-alcoholic fatty liver disease exhibited high energy and lipid consumption, most of them had inadequate intake of some micronutrients. The possible role of nutrient-deficient intake in the development of non-alcoholic fatty liver disease warrants investigation.

  16. Change in the family food environment is associated with positive dietary change in children

    2013-01-01

    Full Text Available Abstract Background The family food environment is an important influence in the development of children’s dietary habits. Research suggests that influences of current dietary behaviour and behaviour change may differ. The aims of this paper were to: (1 investigate the association between the food environment at baseline and change in children’s saturated fat intake; and (2 to explore whether a change in the food environment was associated with a change in children’s saturated fat intake. Method Secondary analysis of a 12 week cluster randomised controlled trial in 133 4-13 year old children. Families were randomly allocated to parental education regarding changing to reduced-fat dairy foods or a comparison non-dietary behaviour. The interventions were family focused. Parents received education from a dietitian in 3x30minute sessions to facilitate behaviour change. Parents completed a comprehensive questionnaire capturing three domains of the food environment – Parent knowledge and attitudes; shaping practices; and behaviours and role modelling. Children’s dietary intake was assessed via multiple 24-hour recalls at baseline and week 12. Changes in the family food environment and primary outcome (saturated fat were calculated. Hierarchical linear regression models were performed to explore the association between baseline and change in food environment constructs and change in saturated fat intake. Standardised Beta are presented (p Results After adjustments for child and family demographics, higher levels of perceived food availability (β=-0.2 at baseline was associated with greater reduction in saturated fat intake, where as higher perceived responsibility (β=0.2, restriction (β=0.3 and pressure to eat (β=0.3 were associated with lesser change in saturated fat.

  1. Investigation of cattle methane production and emission over a 24-hour period using measurements of δ13C and δD of emitted CH4 and rumen water

    Bilek, R. S.; Tyler, S. C.; Kurihara, M.; Yagi, K.

    2001-07-01

    We have conducted a series of experiments to determine the effects different diets, including the addition of unsaturated fatty acids, had on isotopic signatures of CH4 emissions from dairy cattle. Measurements of emitted δ13CH4, δ13CO2, and δD-CH4 were made on gases collected over a 24-hour period from animal chambers containing individual Holstein cows. Some measurements of δD-H2O from samples collected directly from the rumen were also made. We observed variation in δ13CH4 values with time after feeding and a correlation in δ13C between emitted gases and diet. The average δ13CH4 value, which includes all samples of emitted gases, was -70.6±4.9‰ (n = 57). Measurements of δD-CH4 over the 24-hour sampling period had an average value of -357.8±15.0‰ (n = 56). These δD measurements are among the lightest reported for CH4 produced by cattle. Our cattle data indicate that hydrogen incorporated into the CH4 produced by CO2 reduction in high H2 concentration environments is fractionated to a greater degree than that incorporated in systems with relatively low H2 conditions, such as wetlands. Our results support bacterial studies that have demonstrated large hydrogen fractionation in high H2 concentration systems during methanogenesis.

  13. Consequences of radiotherapy on nutritional status, dietary intake, serum zinc and copper levels in patients with gastrointestinal tract and head and neck cancer

    Malnutrition occurs frequently in cancer patients and is multifactorial and can lead to negative outcomes. So we studied the effect of radiotherapy on nutritional status, weight changes, dietary intake, serum zinc and copper levels. During the period of October to March 2005, 45 cancer patients who referred to the Radiotherapy Center, Imam Khomeini Hospital, Iran were recruited. We assessed the nutritional status of patients using Patient-Generated Subjective Global Assessment (PG-SGA) questionnaire. Patients on the basis of location of radiotherapy classified to mediastinum, head and neck pelvic groups. Changes in dietary intake (using 24 hour recall method) and body weight were evaluated prior to and during radiotherapy. At the onset and the end of radiotherapy, serum levels of Zinc, copper and albumin were determined. After treatment malnutrition increased significantly in all patients (p=0.01) and in head and neck (p=0.007) and pelvic groups (p=0.04). The decreased bodyweight of patients was significant in head and neck (p=0.02) and pelvic groups (p=0.05). The mean daily energy and protein intake of head and neck and pelvic groups decreased during radiotherapy while energy intake increased significantly in mediastinum group (p=0.01). After treatment, significant decreases also observed in mean serum zinc, copper and albumin levels (p<0.05). Because of negative effect of radiotherapy on oral feeding, nutritional assessment and intervention should be an integral part of treatment. Also, it would be worthwhile studying the effect of zinc supplementation on dietary intake and nutritional status of patients. (author)

  15. Assessment of femoral head vascularity by technetium-99m antimony colloid bone marrow imaging within 24 hours of subcapital fracture: a prospective study of 30 patients followed for 2 years

    The rationale of preoperative imaging of bone marrow was based upon the demonstration of histochemical abnormalities secondary to ischaemia which first become apparent in marrow cells of the femoral head following interruption of the blood supply by subcapital fracture. These marrow abnormalities predate changes in bone cells by several days and may explain the absence of abnormality on conventional bone scans performed on avascular femoral heads within 24 hours of subcapital fracture. The use of an endoprosthesis for fresh femoral neck fractures in unselected patients results in high mortality, high infection rate, high incidence of thromboembolic disease and poor long term results. The successful prediction of avascular necrosis in 92% of 28 patients with active bone marrow in the femoral head in this study is sufficiently accurate to allow appropriate selection of patients for internal fixation or primary prosthetic replacement on the basis of preoperative Tc-99m antimony colloid imaging

  16. Action research through stimulated recall

    O'Brien, John

    1993-12-01

    The emphasis in classroom learning research has moved from process-product models to the mediating process paradigm. The stimulated-recall interview and thik aloud techniques are the two main processes that have been used in attempts to find out what goes on inside students' heads while they are learning. For example, this researcher has used the stimulated-recall interview technique to identify the workplace thinking of a marine science researcher, and the in-class thinking of a year eleven biology student. Such studies as these have produced findings with important implications for the classroom teacher in the role of action researcher. This paper describes how to conduct stimulated-recall interviews and discusses some classroom implications from the two studies.

The purpose of the study was to examine recalled emotions and perceived risks induced by manipulation using a short videoclip that recalled the sounds of the alarms and the sights of the missile attacks during the war. Before filling in the study questionnaire in 2008, the experimental group watched a short videoclip recalling the events of the war. The control group did not watch the video before filling in the questionnaire. Using the data provided by questionnaires, we analyzed the effect of recalled emotions on perceived risks in two different regions in Israel: the northern region, which was under missile attack daily during the war, and the central region, which was not under missile attacks. The videoclip had a strong effect on the level of recalled emotions in both regions, but it did not affect risk judgments. The results of the analytical framework in the northern region support both the valence approach, in which negative emotion increases pessimism about risk (Johnson and Tversky, 1983, and the modified appraisal tendency theory, which implies different effects for different emotions (Lerner and Keltner, 2000. The current study emphasizes the effects of recalled emotion in the context of the 2006 Israel-Lebanon war on perceived risks among those in the northern region who were under direct attack compared to those who were not directly exposed to the war. Understanding people's responses to stressful events is crucial, not only when these events take place but also over time, since media-induced emotions can influence appraisals and decisions regarding public policies.

    Full Text Available BACKGROUND: Arsenic is an ubiquitous element linked to carcinogenicity, neurotoxicity, as well as adverse respiratory, gastrointestinal, hepatic, and dermal health effects. OBJECTIVE: Identify dietary sources of speciated arsenic: monomethylarsonic acid (MMA, and dimethylarsinic acid (DMA. METHODS: Age-stratified, sample-weighted regression of NHANES (National Health and Nutrition Examination Survey 2003-2010 data (∼8,300 participants ≥6 years old characterized the association between urinary arsenic species and the additional mass consumed of USDA-standardized food groups (24-hour dietary recall data, controlling for potential confounders. RESULTS: For all arsenic species, the rank-order of age strata for median urinary molar concentration was children 6-11 years > adults 20-84 years > adolescents 12-19 years, and for all age strata, the rank-order was DMA > MMA. Median urinary molar concentrations of methylated arsenic species ranged from 0.56 to 3.52 µmol/mol creatinine. Statistically significant increases in urinary arsenic species were associated with increased consumption of: fish (DMA; fruits (DMA, MMA; grain products (DMA, MMA; legumes, nuts, seeds (DMA; meat, poultry (DMA; rice (DMA, MMA; rice cakes/crackers (DMA, MMA; and sugars, sweets, beverages (MMA. And, for adults, rice beverage/milk (DMA, MMA. In addition, based on US (United States median and 90th percentile consumption rates of each food group, exposure from the following food groups was highlighted: fish; fruits; grain products; legumes, nuts, seeds; meat, poultry; and sugars, sweets, beverages. CONCLUSIONS: In a nationally representative sample of the US civilian, noninstitutionalized population, fish (adults, rice (children, and rice cakes/crackers (adolescents had the largest associations with urinary DMA. For MMA, rice beverage/milk (adults and rice cakes/crackers (children, adolescents had the largest associations.

    The accuracy of dietary assessments has emerged as a major concern in nutritional epidemiology and new dietary assessment tools using computer technology to increase accuracy have been developed in many countries. The purpose of this study was to develop a web-based computer-assisted personal interview system (CAPIS) for conducting dietary assessment and to evaluate its practical utilization among Koreans. The client software was developed using Microsoft's ClickOnce technology, which allows communication with a database system via an http server to add or retrieve data. The system consists of a tracking system for the subject and researcher, a data-input system during the interview, a calculation system for estimating food and nutrient intake, a data-output system for presenting the results, and an evaluation system for assessing the adequacy of nutrient and food intake. Databases of the nutrient composition of common food (n = 3,642), recipes for common dishes (n = 1,886), and photos of serving sizes for food and dishes (n = 4,152) were constructed, and logical processes for data collection, calculation, and output were developed. The functionality, on-site applicability, and efficiency of CAPIS were evaluated in a convenience sample of 181 participants (61 males, 120 females; aged 24 to 85) by comparing with manual 24 hour recall method with paper questionnaire. The CAPIS was functioned adequately in the field survey in terms of completeness of function, security, and compliance of researcher and subjects. Regarding on-site applicability, 23.2%, 32.6%, 35.4%, and 43.7% of subjects reported that CAPIS was easier to recall their diet, to estimate the amount consumed, to communicate with the interviewer, and to concentrate on the interview than the manual method with paper questionnaire, respectively. Although CAPIS required more interview time (9 min 42 sec) compared to the manual method (7 min 30 sec), it saved time and cost for data coding and entry (15 min 35

  5. Arc/Arg3.1 mRNA global expression patterns elicited by memory recall in cerebral cortex differ for remote versus recent spatial memories

    Pavel A Gusev

    2010-05-01

    Full Text Available The neocortex plays a critical role in the gradual formation and storage of remote declarative memories. Because the circuitry mechanisms of systems-level consolidation are not well understood, the precise cortical sites for memory storage and the nature of enduring memory correlates (mnemonic plasticity are largely unknown. Detailed maps of neuronal activity underlying recent and remote memory recall highlight brain regions that participate in systems consolidation and constitute putative storage sites, and thus may facilitate detection of mnemonic plasticity. To localize cortical regions involved in the recall of a spatial memory task, we trained rats in a water maze and then mapped mRNA expression patterns of a neuronal activity marker Arc/Arg3.1 (Arc upon recall of recent (24 hours after training or remote (one month after training memories and compared them with swimming and naive controls. Arc gene expression was significantly more robust 24 hours after training compared to one month after training. Arc expression diminished in the parietal, cingulate and visual areas, but select segments in the prefrontal, retrosplenial, somatosensory and motor cortical showed similar robust increases in the Arc expression. When Arc expression was compared across select segments of sensory, motor and associative regions within recent and remote memory groups, the overall magnitude and cortical laminar patterns of task-specific Arc expression were similar (stereotypical. Arc mRNA fractions expressed in the upper cortical layers (2/3, 4 increased after both recent and remote recall, while layer 6 fractions decreased only after the recent recall. The data suggest that robust recall of remote memory requires an overall smaller increase in neuronal activity within fewer cortical segments. This activity trend highlights the difficulty in detecting the storage sites and plasticity underlying remote memory. Application of the Arc maps may ameliorate this

The aims of the present study were to: (1 quantify estimates of daily net endogenous acid production (NEAP (mEq/d in a sample of otherwise healthy elderly aged 50 years and above; and (2 compare NEAP between the elderly and young to determine the effects of aging, which could contribute to changes in the acid–base balance. Analyses were carried out among 526 elderly and 131 young participants (aged 50–80 and 23–28 years, respectively, all of whom were free of discernible disease, nonsmokers, and not on any chronic medication. Selected anthropometric factors were measured and 24-hour dietary recall was recorded. We used two measures to characterize dietary acid load: (1 NEAP estimated as the dietary potential renal acid load plus organic acid excretion, the latter as a multiple of estimated body surface area; and (2 estimated NEAP based on protein and K. For the young and elderly, the ranges of NEAP were 12.1–67.8 mEq/d and 2.0–78.3 mEq/d, respectively. Regardless of the method used, the mean dietary acid–base balance (NEAP was significantly higher for the elderly than the young (P = 0.0035 for NEAP [elderly, 44.1 mEq/d versus young 40.1 mEq/d]; and P = 0.0035 for the protein:potassium ratio [elderly, 1.4 mEq/d versus young 1

    This paper studies a repeated minority game with public signals, symmetric bounded recall, and pure strategies. We investigate both public and private equilibria of the game with fixed recall size. We first show how public equilibria in such a repeated game can be represented as colored subgraphs of a de Bruijn graph. Then we prove that the set of public equilibrium payoffs with bounded recall converges to the set of uniform equilibrium payoffs as the size of the recall increases. We also sho...

  17. Characterizing the phenomenon of radiation recall dermatitis

    Radiation recall represents the 'recalling' of an effect similar in appearance to that of an acute radiation reaction in a previously irradiated field. The recall is triggered by the administration of certain drugs days to years after the exposure to ionizing radiation. This review focuses almost exclusively on the skin manifestations of radiation recall to assemble the largest data base upon which to discuss this rare phenomenon. No absolute radiation dose threshold is apparent, but rather an interplay between dose and time before drug exposure seems to affect both the risk and speed of onset of recall. Recall usually occurs on first exposure to a particular recall-triggering drug. The skin reaction develops within minutes to days. The time to develop the reaction may be slightly longer for oral than intravenously administered drugs reflecting their bioavailability. Most drugs associated with recall are cytotoxics, but several other drugs may elicit the phenomenon. Individuals exposed to a number of potentially recall-triggering drugs reveal the marked drug specificity characteristic of the phenomenon. Skin reactions usually settle within a few days of stopping the triggering drug. The role of steroids or anti-histamines in affecting resolution is unclear. Drug rechallenge tends to produce either only a mild recurrence or no recurrence of recall. Steroids or dose reduction may favour uneventful rechallenge. A number of aetiological hypotheses on radiation recall exist. Using the available evidence these hypotheses are critically reviewed and a novel hypothesis based on radiation affecting local cutaneous immunological responses proposed

  18. Recall of Events Affects Perception of Happiness

    Angelica Moe

    2014-01-01

    This study assessed the relationships between recall of positive and negative events, API (attention to positive) and ANI (attention to negative information), and perception of happiness, with the hypothesis that recall affects the perception of happiness and that ANI and API affect recall. One hundred and five women filled in the APNI scale to assess API and ANI and were asked to listen to and recall a story presenting both positive and negative events, and provide an assessment of the character perceived happiness. Finally, they were asked to choose an ending for the story. Results showed that recall is related to the perception of happiness more than API and ANI, and that relationships occur among recall, API, ANI, and perception of happiness. A positive ending for the story was preferred. Discussion focuses on the implications of individual differences in paying attention to and recall positive and negative information.

    2006-04-01

    relationship between the epistemology of science and the metaphysics of poetic imagination, two opposed, competing, and complementary traits of Bachelard's philosophy, often expressed by the epithets of "diurnal" and "nocturnal". To study the relationship between these two directions in Bachelard's thought, we start from the analysis of the ambivalence of the following pairs of concepts: epistemological obstacle & material imagination, and psychoanalysis of knowledge & phenomenological method, which structure, theoretically in the case of the former pair, and methodologically in the case of the latter pair, his epistemology of science and his metaphysics of poetic imagination. The results allow us to say that the joining of Bachelard's scientific epistemology and poetical metaphysics is represented in his concept of the "24-hour man". This complex, androgynous man, reader and thinker of the scientific ideas and of the poetical genesis, seems to be an image of the reconciliation of the antinomies expressed by the diurnal and nocturnal facets of the Bachelardian philosophy. Expanding on the imagetic analysis of the "24-hour man" through a myth-analytical hermeneutics, we find the two semblances of Bachelard's philosophy configured, respectively, in the myths of Apollo-Prometheus and Dionysus.

  2. Imprinting and recalling cortical ensembles.

    Carrillo-Reid, Luis; Yang, Weijian; Bando, Yuki; Peterka, Darcy S; Yuste, Rafael

    2016-08-12

    Neuronal ensembles are coactive groups of neurons that may represent building blocks of cortical circuits. These ensembles could be formed by Hebbian plasticity, whereby synapses between coactive neurons are strengthened. Here we report that repetitive activation with two-photon optogenetics of neuronal populations from ensembles in the visual cortex of awake mice builds neuronal ensembles that recur spontaneously after being imprinted and do not disrupt preexisting ones. Moreover, imprinted ensembles can be recalled by single- cell stimulation and remain coactive on consecutive days. Our results demonstrate the persistent reconfiguration of cortical circuits by two-photon optogenetics into neuronal ensembles that can perform pattern completion. PMID:27516599

    Pilar Guallar-Castillón

    Full Text Available OBJECTIVE: To assess the validity and reproducibility of food and nutrient intake estimated with the electronic diet history of ENRICA (DH-E, which collects information on numerous aspects of the Spanish diet. METHODS: The validity of food and nutrient intake was estimated using Pearson correlation coefficients between the DH-E and the mean of seven 24-hour recalls collected every 2 months over the previous year. The reproducibility was estimated using intraclass correlation coefficients between two DH-E made one year apart. RESULTS: The correlations coefficients between the DH-E and the mean of seven 24-hour recalls for the main food groups were cereals (r = 0.66, meat (r = 0.66, fish (r = 0.42, vegetables (r = 0.62 and fruits (r = 0.44. The mean correlation coefficient for all 15 food groups considered was 0.53. The correlations for macronutrients were: energy (r = 0.76, proteins (r= 0.58, lipids (r = 0.73, saturated fat (r = 0.73, monounsaturated fat (r = 0.59, polyunsaturated fat (r = 0.57, and carbohydrates (r = 0.66. The mean correlation coefficient for all 41 nutrients studied was 0.55. The intraclass correlation coefficient between the two DH-E was greater than 0.40 for most foods and nutrients. CONCLUSIONS: The DH-E shows good validity and reproducibility for estimating usual intake of foods and nutrients.

  7. Factors affecting reading recall(Part 1)

    Hirano, Kinue

    2004-01-01

    Previous research has investigated whether many variables affect a reader's ability to understand and recall a text written in a first or second language. The present study reviewed some of the literature related to factors that affect reading recall: background knowledge, the syntactic complexity of the text, the language of recall, the importance of the structure of a passage, story schema, and sex differences and reading ability. Thus the factors considered in this paper should be taken in...

In this paper we demonstrate that the relationship between perfect recall and bounded recall is not straightforward: The decision maker with ...

  9. Separable Prefrontal Cortex Contributions to Free Recall

    Long, Nicole M.; Öztekin, Ilke; Badre, David

    2010-01-01

    In everyday life, we often must remember the past in the absence of helpful cues in the environment. In these cases, the brain directs retrieval by relying on internally maintained cues and strategies. Free recall is a widely used behavioral paradigm for studying retrieval with minimal cue support. During free recall, individuals often recall semantically related items consecutively—an effect termed semantic clustering—and previous studies have sought to understand clustering to gain leverage...

    Ireland, Dani-Maree; Clifton, Peter M; Keogh, Jennifer B

    2010-05-01

    There are national targets for salt intake of 6 g salt/day in Australia and the United States. Despite this, there is limited knowledge about the effectiveness of dietary education in reducing salt intake to this level. The objective of this study was to investigate whether dietary education enabled a reduction in salt consumption. In an 8-week parallel study, 49 healthy free-living adults were recruited from the Adelaide community by newspaper advertisement. In a randomized parallel design, participants received dietary education to choose foods identified by either Australia's National Heart Foundation Tick symbol or by the Food Standards Australia and New Zealand's low-salt guideline of 120 mg sodium/100 g food. Sodium excretion was assessed by 24-hour urinary sodium collections at baseline and weeks 4 and 8. Participants' experiences of following the education strategies were recorded by self-administered questionnaire. These data were collected between August and October 2008. Forty-three participants completed the study. After 8 weeks, urinary sodium excretion decreased from 121+/-50 to 106+/-47 mmol/24 hours (7.3+/-3.0 to 6.4+/-2.8 g salt/24 hours) in the Tick group and from 132+/-44 to 98+/-50 mmol/24 hours (7.9+/-2.6 to 6.0+/-3.0 g salt/24 hours) in the Food Standards Australia New Zealand group (Pfood choice, difficulty when eating out, and increased time associated with identifying foods. In conclusion, dietary sodium reduction is possible among free-living individuals who received dietary advice. PMID:20430138

  12. Evaluation of the embolic effect of polyvinyl alcohol foam particles according to particle size on the cerebral artery of a cat, focusing on T2 weighted MR images and pathologic study after 24 hours

    This study was designed to determine the embolic effect of PVA particles of various sizes on the cerebral artery of a cat and to determine the appropriate particle size for embolization. A total of 21 cats were divided into three groups according to the PVA particle size injected: group I (n=3D7), embolized with 45-150μm PVA; group II (n=3D7), with 150-250μm PVA; and group III (n=3D7), with 350-500μm PVA. PVA particles were slowly injected into the left common carotid artery of each cat, and T2-weighted coronal MR images were obtained 24 hours after injection. During histologic examination of brain sections we analyzed the size, number of occluded vessels, and the ischemic changes caused by the particles. On T2 weighted images, areas of high signal intensity (infarction) were observed in four of the seven cats (57%) in group I and in two of the seven (29%) II. High signal intensity was not found in group III. The mean percentage of areas of high signal intensity was 11.86 ± 1.37% in group I and 5.18 ± 1.77% in group II (P less than 0.05). During histologic examination, occlusion of the distal branches of the anterior cerebral (ACA) and/or the middle cerebral arteries (MCA) by PVA particles was observed in all seven cats (100%) in group I, and in four of the seven cats (57%) in group II, No group III cat showed occlusion of the distal branches of the ACA and/or MCA. The mean caliber of occluded vessels was 175μm in Group I and 258μm in Group II. The mean number of occluded vessels seen on all slide sections was 14 in Group I and 5 in Group II. Small PVA particles has a greater cerebral embolic effect than did those which were medium or large. For the induction of embolic infarction in cat brain, PVA particles 45-150μm in size are appropriate. (author)

  13. The otolaryngologic manifestations of gastroesophageal reflux disease (GERD): a clinical investigation of 225 patients using ambulatory 24-hour pH monitoring and an experimental investigation of the role of acid and pepsin in the development of laryngeal injury.

    Koufman, J A

    1991-04-01

    Occult (silent) gastroesophageal reflux disease (GER, GERD) is believed to be an important etiologic factor in the development of many inflammatory and neoplastic disorders of the upper aerodigestive tract. In order ot test this hypothesis, a human study and an animal study were performed. The human study consisted primarily of applying a new diagnostic technique (double-probe pH monitoring) to a population of otolaryngology patients with GERD to determine the incidence of overt and occult GERD. The animal study consisted of experiments to evaluate the potential damaging effects of intermittent GER on the larynx. Two hundred twenty-five consecutive patients with otolaryngologic disorders having suspected GERD evaluated from 1985 through 1988 are reported. Ambulatory 24-hour intraesophageal pH monitoring was performed in 197; of those, 81% underwent double-probe pH monitoring, with the second pH probe being placed in the hypopharynx at the laryngeal inlet. Seventy percent of the patients also underwent barium esophagography with videofluoroscopy. The patient population was divided into seven diagnostic subgroups: carcinoma of the larynx (n = 31), laryngeal and tracheal stenosis (n = 33), reflux laryngitis (n = 61), globus pharyngeus (n = 27), dysphagia (n = 25), chronic cough (n = 30), and a group with miscellaneous disorders (n = 18). The most common symptoms were hoarseness (71%), cough (51%), globus (47%), and throat clearing (42%). Only 43% of the patients had gastrointestinal symptoms (heartburn or acid regurgitation). Thus, by traditional symptomatology, GER was occult or silent in the majority of the study population. Twenty-eight patients (12%) refused or could not tolerate pH monitoring. Of the patients undergoing diagnostic pH monitoring, 62% had abnormal esophageal pH studies, and 30% demonstrated reflux into the pharynx. The results of diagnostic pH monitoring for each of the subgroups were as follows (percentage with abnormal studies): carcinoma (71

  14. Are forwards and backwards digit recall the same? A dual task study of digit recall

    St. Clair-Thompson, HL; Allen, RJ

    2013-01-01

    There is some debate surrounding the cognitive resources underlying backwards digit recall. Some researchers consider it to differ from forwards digit recall due to the involvement of executive control, while others suggest that backwards recall involves visuo-spatial resources. Five experiments therefore investigated the role of executive-attentional and visuo-spatial resources in both forwards and backwards digit recall. In the first, participants completed visuo-spatial 0-back and 2-back t...

  1. Nutrition Concerns of Insufficient and Excessive Intake of Dietary Minerals in Lactating Women: A Cross-Sectional Survey in Three Cities of China.

    Ai Zhao

    Full Text Available Objectives of this study were 1 to investigate the mineral intake by Chinese lactating women, 2 to explore the dietary source of minerals, and 3 the ratios between different dietary minerals.A total of 468 lactating women in 5-240 days post-partum participated in this study. Food intakes by participants were measured using one time of 24-hour dietary recall, and minerals from food were calculated based on the Chinese Food Composition Table, second edition.In post-partum, women had inadequate food intake. 81.0% of women's daily intake of dairy products was lower than 300g, and 97.1% of women's daily intake of salt over 6g. For mineral intake, there were 81.8%, 59.0%, 47.6%, 45.7% and 66.8% of women's calcium, magnesium, iron, zinc and selenium intake lower than the estimated average requirement, respectively, and 91.7% of women's excessive intake of sodium. The calcium/phosphorus and sodium/potassium ratios were 0.41±0.26/1 and 3.13±2.89/1, respectively. Considering the dietary sources of minerals, 27.3%, 25.3% and 30.1% of iron, zinc and calcium were from animal-based food, respectively, and 60.3%, 66.1% and 58.0% of iron, zinc and calcium were from plant-based food, respectively. The phosphorus-protein ratio was 0.014±0.003/1. Lactation stage was associated with nutrient intake. Women within 30 days post-partum and the ones who live in Guangzhou had a significantly lower intake of certain minerals, while women with a high education experience had a high intake of calcium, potassium, iron and zinc. Productive age, whether obese or not, and delivery ways were not associated with mineral intakes (P all >0.05.Chinese women in three studied cities had an inappropriate food intake and resulted in both insufficient and excessive intakes of certain minerals.

    2011-12-01

    Full Text Available PURPOSE: To evaluate the mitochondrial function of the remnant liver (RL in the early phase of liver regeneration in rats after 70% partial hepatectomy (PH. METHODS: Sixty male Wistar rats (200-250g submitted to 70% PH were divided into five groups according to the time of euthanasia and application or not of laser light: C = Control, time zero; 2 minutes, 4, 6 and 24 hours after PH. The dose of laser radiation was 22.5 J/cm², wavelength of 660 nm (visible/red, in the remnant liver. We studied the respiration activated by ADP (state 3, basal mitochondrial respiration (state 4, respiratory control ratio (RCR and mitochondrial membrane potential (MMP. RESULTS: The mitochondrial function of RL changed at 4 and 6 hours after PH, with a significant increase in state 3 and a concomitant increase in state 4 and with maintenance of RCR. MMP differed significantly between the groups biostimulated with laser radiation and the control group 4 hours after HP, with a substantial reduction in the non-laser groups. CONCLUSION: The laser light at the dose used in this study did not induce additional damage to the RL and seems to have delayed the hepatocellular metabolic overload of the remnant liver.OBJETIVO: Avaliar a função mitocondrial do fígado remanescente (FR na fase precoce da regeneração hepática em ratos após hepatectomia parcial (HP a 70%.

  3. Consensus collaboration enhances group and individual recall accuracy

    Harris, Celia Bernadette; Barnier, Amanda J.; Sutton, John

    2012-01-01

    We often remember in groups, yet research on collaborative recall finds “collaborative inhibition”: Recalling with others has costs compared to recalling alone. In related paradigms, remembering with others introduces errors into recall. We compared costs and benefits of two collaboration...... procedures—turn taking and consensus. First, 135 individuals learned a word list and recalled it alone (Recall 1). Then, 45 participants in three-member groups took turns to recall, 45 participants in three-member groups reached a consensus, and 45 participants recalled alone but were analysed as three......-member nominal groups (Recall 2). Finally, all participants recalled alone (Recall 3). Both turn-taking and consensus groups demonstrated the usual pattern of costs during collaboration and benefits after collaboration in terms of recall completeness. However, consensus groups, and not turn-taking groups...

  4. Quantum bounce and cosmic recall

    Corichi, Alejandro

    2007-01-01

    Loop quantum cosmology predicts that, in simple models, the big bang singularity of classical general relativity is replaced by a quantum bounce. Because of the extreme physical conditions near the bounce, a natural question is whether the universe can retain, after the bounce, its memory about the previous epoch. More precisely, does the universe recall various properties of the state after evolving unitarily through the bounce or does it suffer from cosmic amnesia as has been recently suggested? Here we show that this issue can be answered unambiguously by means of an exactly solvable model, derived from a small simplification of loop quantum cosmology, for which there is full analytical control on the quantum theory. We show that if there exists a semi-classical state at late times on one side, peaked around a pair of canonically conjugate variables, then there are very strong bounds on the fluctuations on the other side of the bounce, implying semi-classicality. For a model universe which grows to a size ...

  5. Exploring the relationship between retrieval disruption from collaboration and recall

    Barber, Sarah J.; Rajaram, Suparna

    2011-01-01

    When people recall together in a collaborative group, they recall less than their potential. This phenomenon of collaborative inhibition is explained in terms of retrieval disruption. However, collaborative recall also re-exposes individuals to items recalled by others that they themselves might otherwise have forgotten. This re-exposure produces post-collaborative benefits in individual recall. The current study examined whether reduced retrieval disruption during group recall is related not...

  6. Children's very low food security is associated with increased dietary intakes in energy, fat, and added sugar among Mexican-origin children (6-11 y in Texas border Colonias

    Sharkey Joseph R

    2012-02-01

    Full Text Available Abstract Background Food insecurity among Mexican-origin and Hispanic households is a critical nutritional health issue of national importance. At the same time, nutrition-related health conditions, such as obesity and type 2 diabetes, are increasing in Mexican-origin youth. Risk factors for obesity and type 2 diabetes are more common in Mexican-origin children and include increased intakes of energy-dense and nutrient-poor foods. This study assessed the relationship between children's experience of food insecurity and nutrient intake from food and beverages among Mexican-origin children (age 6-11 y who resided in Texas border colonias. Methods Baseline data from 50 Mexican-origin children were collected in the home by trained promotora-researchers. All survey (demographics and nine-item child food security measure and 24-hour dietary recall data were collected in Spanish. Dietary data were collected in person on three occasions using a multiple-pass approach; nutrient intakes were calculated with NDS-R software. Separate multiple regression models were individually fitted for total energy, protein, dietary fiber, calcium, vitamin D, potassium, sodium, Vitamin C, and percentage of calories from fat and added sugars. Results Thirty-two children (64% reported low or very low food security. Few children met the recommendations for calcium, dietary fiber, and sodium; and none for potassium or vitamin D. Weekend intake was lower than weekday for calcium, vitamin D, potassium, and vitamin C; and higher for percent of calories from fat. Three-day average dietary intakes of total calories, protein, and percent of calories from added sugars increased with declining food security status. Very low food security was associated with greater intakes of total energy, calcium, and percentage of calories from fat and added sugar. Conclusions This paper not only emphasizes the alarming rates of food insecurity for this Hispanic subgroup, but describes the

  11. Reminiscence and item recovery in free recall.

    Madigan, S

    1976-05-01

    The item recovery or reminiscence component of recall in RTT procedures was investigated in two free recall experiments. In the first, Erdelyi and Becker's (1974) "hypermnesia" effect was found with pictures as the to-be-remembered material: total amount recalled increased over two successive test trials, and included a large reminiscence effect, with some 27% of previously unrecalled items appearing in the second test. The second experiment, with word lists, showed that the frequency of occurrence of new items was greater following a 12-min separation of two test trials than in two relatively massed tests. This kind of item recovery is relevant to models of output interference and retrieval limitations in free recall, and may be also related to spontaneous recovery effects. PMID:21287027

  12. Adiabatic Quantum Optimization for Associative Memory Recall

    Hadayat eSeddiqi

    2014-12-01

    Full Text Available Hopfield networks are a variant of associative memory that recall patterns stored in the couplings of an Ising model. Stored memories are conventionally accessed as fixed points in the network dynamics that correspond to energetic minima of the spin state. We show that memories stored in a Hopfield network may also be recalled by energy minimization using adiabatic quantum optimization (AQO. Numerical simulations of the underlying quantum dynamics allow us to quantify AQO recall accuracy with respect to the number of stored memories and noise in the input key. We investigate AQO performance with respect to how memories are stored in the Ising model according to different learning rules. Our results demonstrate that AQO recall accuracy varies strongly with learning rule, a behavior that is attributed to differences in energy landscapes. Consequently, learning rules offer a family of methods for programming adiabatic quantum optimization that we expect to be useful for characterizing AQO performance.

    2015-01-01

    Negative priming in free recall is the finding of impaired memory performance when previously ignored auditory distracters become targets of encoding and retrieval. This negative priming has been attributed to an aftereffect of deploying inhibitory mechanisms that serve to suppress auditory distraction and minimize interference with learning and retrieval of task-relevant information. In 6 experiments, we tested the inhibitory account of the effect of negative priming in free recall against a...

    Full Text Available OBJECTIVE: To determine the reliability and validity of the Multimedia Activity Recall for Children and Adults (MARCA in people with chronic obstructive pulmonary disease (COPD. DESIGN: People with COPD and their carers completed the Multimedia Activity Recall for Children and Adults (MARCA for four, 24-hour periods (including test-retest of 2 days while wearing a triaxial accelerometer (Actigraph GT3X+®, a multi-sensor armband (Sensewear Pro3® and a pedometer (New Lifestyles 1000®. SETTING: Self reported activity recalls (MARCA and objective activity monitoring (Accelerometry were recorded under free-living conditions. PARTICIPANTS: 24 couples were included in the analysis (COPD; age 74.4 ± 7.9 yrs, FEV1 54 ± 13% Carer; age 69.6 ± 10.9 yrs, FEV1 99 ± 24%. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Test-retest reliability was compared for MARCA activity domains and different energy expenditure zones. Validity was assessed between MARCA-derived physical activity level (in metabolic equivalent of task (MET per minute, duration of moderate to vigorous physical activity (min and related data from the objective measurement devices. Analysis included intra-class correlation coefficients (ICC, Bland-Altman analyses, paired t-tests (p and Spearman's rank correlation coefficients (rs. RESULTS: Reliability between occasions of recall for all activity domains was uniformly high, with test-retest correlations consistently >0.9. Validity correlations were moderate to strong (rs = 0.43-0.80 across all comparisons. The MARCA yields comparable PAL estimates and slightly higher moderate to vigorous physical activity (MVPA estimates. CONCLUSION: In older adults with chronic illness, the MARCA is a valid and reliable tool for capturing not only the time and energy expenditure associated with physical and sedentary activities but also information on the types of activities.

    Little is known about the dietary patterns of Asian infants in the first year of life, nor of their associations with maternal socio-demographic factors. Based on the Growing Up in Singapore towards healthy Outcomes (GUSTO) mother-offspring cohort, cross-sectional dietary patterns were derived by factor analysis using 24-h recalls and food diaries of infants at 6-, 9- and 12-months of age. Dietary pattern trajectories were modeled by mapping similar dietary patterns across each age using mult...

  2. Short Tools to Assess Young Children's Dietary Intake: A Systematic Review Focusing on Application to Dietary Index Research

    Lucinda K. Bell

    2013-01-01

    Full Text Available Dietary indices evaluate diet quality, usually based on current dietary guidelines. Indices can therefore contribute to our understanding of early-life obesity-risk dietary behaviours. Yet indices are commonly applied to dietary data collected by onerous methods (e.g., recalls or records. Short dietary assessment instruments are an attractive alternative to collect data from which to derive an index score. A systematic review of studies published before April 2013 was conducted to identify short (≤50 items tools that measure whole-of-diet intake of young children (birth-five years and are applicable to dietary indices, in particular screening obesogenic dietary behaviours. The search identified 3686 papers of which 16, reporting on 15 tools (n=7, infants and toddlers birth-24 months; n=8, preschoolers 2–5 years, met the inclusion criteria. Most tools were food frequency questionnaires (n=14, with one innovative dietary questionnaire identified. Seven were tested for validity or reliability, and one was tested for both. Six tools (n=2, infants and toddlers; n=4, preschoolers are applicable for use with current dietary indices, five of which screen obesogenic dietary behaviours. Given the limited number of brief, valid and reliable dietary assessment tools for young children to which an index can be applied, future short tool development is warranted, particularly for screening obesogenic dietary behaviours.

    2013-01-01

    Full Text Available ABSTRACTObjective: To assess the nutritional status and other nutrition related problems of the workers. To design, implement and evaluate the impact of dietary intervention for the nutritional metabolic disorder which is directly related to productivity.Background: Indian economy greatly relies on agriculture. Agriculture is set to play a more dynamic role in the economy. The present study focuses on the nutritional status with special reference to the blood iron profile of manual coffee plantation laborers belonging to Kodaikannal, Tamil Nadu, India. The outcome of this study on the dietary intervention, based on nutritional picture of coffee plantation laborers, will have a nationwide application because of the simplified, stable coffee plantation operations throughout India.Method: Experiments were carried out in three phases. In the first phase, the personal background of the laborers was assessed. In the second phase, the nutritional and health status of the laborers, through dietary survey comprising 24 Hour Food Recall record and weighment of cooked food consumed for three consecutive days, clinical and biochemical profile were studied. The serum iron was measured with the total iron binding capacity, from which the transferrin saturation was calculated. In the third phase, dietary intervention was implemented with a nutrient rich nutraceutical food supplement - spirulina incorporated soup. The supplementation was extended for a period of 120 days. The subjects were grouped into control and the experimental group. The control group was given plain soup and the experimental group was administered with soup incorporated with spirulina. The impact of intervention on the biochemical and nutritional profile of the laborers was reassessed in similar working conditions.Results: A deficit of 0.1 mg to 0.3 mg of iron intake per kg body weight in the male and female laborers was observed when compared to their RDA The clinical pictures reveal that

    Jia, Wenyan; Yue, Yaofeng; Fernstrom, John D.; YAO, Ning; Sclabassi, Robert J.; Fernstrom, Madelyn H.; Sun, Mingui

    2011-01-01

    Measuring food volume (portion size) is a critical component in both clinical and research dietary studies. With the wide availability of cell phones and other camera-ready mobile devices, food pictures can be taken, stored or transmitted easily to form an image based dietary record. Although this record enables a more accurate dietary recall, a digital image of food usually cannot be used to estimate portion size directly due to the lack of information about the scale and orientation of the ...

    Recall latency, recall accuracy rate, and recall confidence were examined in free recall as a function of recall output serial position using a modified Deese-Roediger-McDermott paradigm to test a strength-based theory against the dual-retrieval process theory of recall output sequence. The strength theory predicts the item output sequence to be in the descending order of memory strength. The dual-retrieval process theory postulates two phases in a free recall, a first direct access phase in ...

  17. Emphasizing Expert Practice with Spaced Recall

    Torigoe, Eugene T

    2015-01-01

    This paper explores an intervention that emphasizes expert practice using spaced recall. Interviews were performed with two students who were shown physics solutions, and were asked to repeatedly recall the solutions over a period of weeks. The students reflected that they became aware of the importance of using the diagrams to create equations, as well as the utility of reasoning over pure memorization. We believe that the structure of this activity may be an effective way of encouraging expert practice to introductory physics students.

    2016-01-01

    Recalls of non-prescription drugs can contribute to preventing harm to human health, however, they also interrupt the supply of medicines to the market. The aim of the present study was to investigate the trends in non-prescription drug recalls in Japan. Class I, II, and III recalls reported from April 2009 to March 2014 were obtained from the websites of the Ministry of Health, Labour and Welfare and the Pharmaceuticals and Medical Devices Agency. Each drug recall was classified according to year, dosage form, therapeutic category, and reasons for the recall. The trends over the 5 year period were assessed for each class. A total of 220 recalls were reported in the 5-year study period. The numbers of drug recalls were 21, 16, 80, 58, and 45 in 2009, 2010, 2011, 2012, and 2013, respectively. The drugs recalled consisted of 177 internal medications, 35 topical agents, and 8 others. Drug recalls were observed in 12 therapeutic categories of drug effects. The largest number of recalls was for Chinese herbal medicines and crude drugs. Of all the drug recalls in 2011, Chinese herbal medicines and crude drugs produced by one manufacturer accounted for 84%. Slightly more than half (54%) of drug recalls were due to a violation of the regulations. One manufacturer recalled many drugs because of non-compliance with the standard regulations for manufacturing drugs after 2011. In conclusion, non-prescription drug recalls can occur for any drug regardless of the dosage form and therapeutic category. PMID:27592833

  20. Recalling and forgetting dreams: theta and alpha oscillations during sleep predict subsequent dream recall.

    Marzano, Cristina; Ferrara, Michele; Mauro, Federica; Moroni, Fabio; Gorgoni, Maurizio; Tempesta, Daniela; Cipolli, Carlo; De Gennaro, Luigi

    2011-05-01

    Under the assumption that dream recall is a peculiar form of declarative memory, we have hypothesized that (1) the encoding of dream contents during sleep should share some electrophysiological mechanisms with the encoding of episodic memories of the awake brain and (2) recalling a dream(s) after awakening from non-rapid eye movement (NREM) and rapid eye movement (REM) sleep should be associated with different brain oscillations. Here, we report that cortical brain oscillations of human sleep are predictive of successful dream recall. In particular, after morning awakening from REM sleep, a higher frontal 5-7 Hz (theta) activity was associated with successful dream recall. This finding mirrors the increase in frontal theta activity during successful encoding of episodic memories in wakefulness. Moreover, in keeping with the different EEG background, a different predictive relationship was found after awakening from stage 2 NREM sleep. Specifically, a lower 8-12 Hz (alpha) oscillatory activity of the right temporal area was associated with a successful dream recall. These findings provide the first evidence of univocal cortical electroencephalographic correlates of dream recall, suggesting that the neurophysiological mechanisms underlying the encoding and recall of episodic memories may remain the same across different states of consciousness.

  5. Feasibility and validity of mobile phones to assess dietary intake.

    Sharp, Darren B; Allman-Farinelli, Margaret

    2014-01-01

    Current limitations of conventional dietary assessment methods restrict the establishment of diet-disease relationships and efficacy of dietary interventions. Technology, in particular the use of mobile phones, may help resolve methodologic limitations, in turn improving the validity of dietary assessment and research and associated findings. This review aims to evaluate the validity, feasibility, and acceptability of dietary assessment methods that have been deployed on mobile phone platforms. In August 2013, electronic databases for health sciences were searched for English, peer-reviewed, full-text articles, published from January 1, 2001 onward; and accompanied by a hand search of available relevant publications from universities and government bodies. Studies were not limited by design, length, setting, or population group. Of 194 articles, 12 met eligibility criteria: mobile phone as the dietary recording platform and validation of energy and/or macronutrient intake against another dietary or biological reference method. Four dietary recoding methods had been validated on mobile phone platforms: electronic food diary, food photograph-assisted self-administered, 24 h recall, food photograph analysis by trained dietitians, and automated food photograph analysis. All mobile phone dietary assessment methods showed similar, but not superior, validity or reliability when compared with conventional methods. Participants' satisfaction and preferences for mobile phone dietary assessment methods were higher than those for conventional methods, indicating the need for further research. Validity testing in larger and more diverse populations, over longer durations is required to evaluate the efficacy of these methods in dietary research. PMID:24976425

    If you draw from memory a picture of the front of your childhood home, you will have demonstrated recall. You could also recognize this house upon seeing it. Unlike recognition, recall demonstrates memory for things that are not present. Recall is necessary for planning and imagining, and can increase the flexibility of navigation, social behavior, and other cognitive skills. Without recall, memory is more limited to recognition of the immediate environment. Amnesic patients are impaired on r...

  19. An investigation and analysis for dietary nutrition in bedridden elderly patients%60岁以上卧床患者膳食营养调查分析

    王纯; 刘闰红; 孟文颖; 冯莹; 郑挺

    2011-01-01

    In total, 607 bedridden patients aged 60 years and over at Tianlin community hospital and four other hospitals or at home-care in Shanghai were investigated with questionnaire, physical examinations and related laboratory tests. Contents of investigation include general situation, medical conditions, 24-hour recall of diet, intake of nutritional supplement preparation, and so on. As compare to the reference for nutrient intake of the elderly set in the Guide to Diet for Chinese Residents (2007), total nutritional intake was obviously insufficient and three nutrients in diet were imbalanced for most bedridden elderly patients. Intake of most nutrients (including proteins, dietary fiber, calcium, iron, zinc, selenium,copper, magnesium, phosphor, retinol equivalent, vitamin B1 , vitamin B2, vitamin C) was obviously low in bedridden elderly patients, with a larger gap from the requirements of the Dietary Guide.%采用问卷调查、体格检查和相关实验室检查等方式,对田林社区及本市四所医院共607例住院及家庭病床老年患者(≥60岁)进行调查.问卷内容包括一般情况、疾病调查、膳食回顾及服用营养补充剂等情况.大多数老年患者存在营养总量摄入不足、三大营养素摄入不均衡、大多数营养素(蛋白质、膳食纤维、钙、铁、锌、硒、铜、镁、磷、视黄醇当量、维生素B1、维生素B2、维生紊C)摄入置明显不足等情况,与(2007)参考摄入量差距较大.

  1. Some structural determinants of melody recall.

    Boltz, M

    1991-05-01

    Sophisticated musicians were asked to recall, using musical notation, a set of unfamiliar folk tunes that varied in rhythmic structure and referents of tonality. The results showed that memory was facilitated by tonic triad members marking phrase endings, but only when their presence was highlighted by a corresponding pattern of temporal accents. Conversely, recall significantly declined when tonal information was either absent or obscured by rhythmic structure. Error analyses further revealed that the retention of overall pitch contour and information at phrase ending points varied as a function of these manipulations. The results are discussed in terms of a framework that links the acts of perceiving and remembering to a common attentional scheme. PMID:1861610

  2. Stimulated recall interviews for describing pragmatic epistemology

    Shubert, Christopher W.; Meredith, Dawn C.

    2015-12-01

    Students' epistemologies affect how and what they learn: do they believe physics is a list of equations, or a coherent and sensible description of the physical world? In order to study these epistemologies as part of curricular assessment, we adopt the resources framework, which posits that students have many productive epistemological resources that can be brought to bear as they learn physics. In previous studies, these epistemologies have been either inferred from behavior in learning contexts or probed through surveys or interviews outside of the learning context. We argue that stimulated recall interviews provide a contextually and interpretively valid method to access students' epistemologies that complement existing methods. We develop a stimulated recall interview methodology to assess a curricular intervention and find evidence that epistemological resources aptly describe student epistemologies.

  3. Radiation recall--another call with tamoxifen

    Tamoxifen, a nonsteroidal anti oestrogen, has been used as an adjuvant therapy in patients with oestrogen-receptor positive breast cancer for more than 10 years. Few cutaneous adverse side-effects of the skin are found with this therapy. In this study we present 20 cases of adverse skin effects in relation to tamoxifen during 1979-1997 reported to the Swedish Adverse Drug Reaction Register and 1160 skin side-effects reported to he World Health Organisation's International Collaborative Programme on Drug Monitoring. One new case report of radiation recall in conjunction to tamoxifen, with no sign of reactivation despite 18 months treatment with the tamoxifen analogue toremifene is also discussed in detail. This case illustrates that toremifene can be used as a second-line therapy in patients who have received radiation recall, on tamoxifen

  4. Accelerating Deep Learning with Shrinkage and Recall

    Zheng, Shuai; Vishnu, Abhinav; Ding, Chris

    2016-01-01

    Deep Learning is a very powerful machine learning model. Deep Learning trains a large number of parameters for multiple layers and is very slow when data is in large scale and the architecture size is large. Inspired from the shrinking technique used in accelerating computation of Support Vector Machines (SVM) algorithm and screening technique used in LASSO, we propose a shrinking Deep Learning with recall (sDLr) approach to speed up deep learning computation. We experiment shrinking Deep Lea...

    Tetanus is a serious, often fatal disease that should be completely preventable by appropriate immunization. The present study, done in an urban family practice group, examined the correlation between patients' recollection of their most recent tetanus booster, and the actual date, obtained from office records. Forty-three of the 62 patients (69%) estimated within a year of the correct date; 33 (53%) recalled the date accurately. Recent information on the epidemiology of tetanus is discussed,...

  7. Examining the Relationship between Free Recall and Immediate Serial Recall: The Role of List Length, Strategy Use, and Test Expectancy

    Grenfell-Essam, Rachel; Ward, Geoff

    2012-01-01

    Recent findings suggest that the immediate free recall (IFR) of short lists is similar to immediate serial recall (ISR). These findings were obtained using a methodology in which participants did not know the list length in advance of each list, and this uncertainty may have encouraged participants to adopt atypical recall strategies. Therefore,…

  14. 24-hour secretory pattern of dehydroisoandrosterone and dehydroisoandrosterone sulfate

    Dehydroisoandrosterone (DHA) and cortisol were measured by radioimmunoassay and protein binding techniques respectively in plasma from blood taken at 20-min intervals over 24-h periods in 3 normal men, 2 women with Stein-Leventhal syndrome, and a man with a benign adrenocortical adenoma. In all subjects but the latter, DHA and cortisol were episodic and synchronous throughout the entire day; in this patient, continuous secretion of cortisol by the tumor apparently abolished stimulation of the contralateral adrenal, and DHA production was negligible. Dehydroisoandrosterone sulfate analyses in plasma displayed a pattern which, probably because of its origin both by secretion and sulfation and its long half-life, showed less synchronicity with DHA and cortisol and less fluctuation than did the free hormones.

  16. Noninvasive 24-hour ambulatory arterial blood pressure monitoring in cirrhosis

    Møller, Søren; Wiinberg, N; Henriksen, Jens Henrik

    1995-01-01

    Cirrhotic patients have disturbed systemic hemodynamics with reduced arterial blood pressure, but this has not been investigated during daily activity and sleep. Systolic (SBP), diastolic (DBP), and mean arterial blood pressure (MAP), and heart rate (HR) were measured by an automatic ambulant...... device for monitoring blood pressure in 35 patients with cirrhosis and 35 healthy matched controls. During the daytime, SBP, DBP, and MAP were significantly lower in the patients than in the controls (median 118 vs. 127; 70 vs. 78; 86 vs. 94 mm Hg, P < .0001 to P < .05). The nighttime blood pressures...... were almost similar in the two groups (108 vs. 110; 65 vs. 67; 78 vs. 82 mm Hg, NS). Conversely, HR was significantly higher in the patients both in the daytime (86 vs. 72/min, P < .0001) and at night (80 vs. 64/min, P < .0001). Consequently, the reduction in blood pressure and HR from daytime to...

    1986-01-01

    A relation between the prevalence of asthma and economic development has been suggested by studies in migrants and other surveys in developing countries. That this correlation might be partially explained by an increased intake of salt in the diet is supported by the observation that sales of table salt in the different regions of England and Wales are independently correlated with mortality from asthma for men and for children. As part of a wider survey of asthma 138 men living in two Hampsh...

  20. Nutrition habits in 24-hour mountain bike racers.

    Chlíbková, Daniela; Knechtle, Beat; Rosemann, Thomas; Tomášková, Ivana; Chadim, Vlastimil; Shortall, Marcus

    2014-01-01

    We investigated seventy-four ultra-mountain bikers (MTBers) competing in the solo category in the first descriptive field study to detail nutrition habits and the most common food before during and after the 24 hour race using questionnaires. During the race, bananas (86.5%), energy bars (50.0%), apples (43.2%) and cheese (43.2%) were the most commonly consumed food, followed by bread (44.6%), rice (33.8%) and bananas (33.8%) after the race. Average fluid intake was 0.5 ± 0.2 l/h. The main beverage was isotonic sports drink (82.4%) during and pure water (66.2%) after the race. The most preferred four supplements in the four weeks before, the day before, during and after the race were vitamin C (35.1%), magnesium (44.6%), magnesium (43.2%) and branched-chain amino acids (24.3%), respectively. Total frequency of food intake (30.6 ± 10.5 times/24 hrs) was associated with fluid intake (r = 0.43, P = 0.04) and both were highest at the beginning of the race and lower during the night hours and the last race segment in a subgroup of twenty-three ultra-MTBers. Supplement intake frequency (6.8 ± 8.4 times/24 hrs) was highest during the night hours and lower at the beginning and end of the race. Elevated food and fluid intake among participants tracked across all race segments (P < 0.001). In conclusion, the nutrition strategy employed by ultra-MTBers was similar to those demonstrated in previous studies of ultra-cyclists with some exceptions among selected individuals. PMID:25674455

  6. Hypermnesia occurs in recall but not in recognition.

    Payne, D G; Roediger, H L

    1987-01-01

    Two experiments investigated the effect of encoding conditions and type of test (recall vs. recognition) on the phenomenon of hypermnesia (improved performance across repeated tests). Subjects in Experiment 1 studied a list of words using either imaginal or semantic elaboration strategies and then received three successive tests. Different groups of subjects received either free recall, four-alternative forced-choice recognition, or yes/no recognition tests. Reliable hypermnesia was found only in the recall conditions, with the recognition conditions showing either no change in performance levels across tests (forced-choice tests) or significant forgetting (yes/no tests). In Experiment 2, subjects studied a list of words, and encoding was manipulated using three orienting tasks. Once again, hypermnesia was found with the recall tests but not with the forced choice recognition tests. Finding hypermnesia in recall but not in recognition indicates that retrieval processes in recall play a major role in producing hypermnesia. Also, the finding that the magnitude of the recall hypermnesias increased with an increase in total cumulative recall levels across study conditions suggests that cumulative recall levels are an important factor in determining the presence or absence of recall hypermnesia.

  10. Memory recall and spike-frequency adaptation

    Roach, James P.; Sander, Leonard M.; Zochowski, Michal R.

    2016-05-01

    The brain can reproduce memories from partial data; this ability is critical for memory recall. The process of memory recall has been studied using autoassociative networks such as the Hopfield model. This kind of model reliably converges to stored patterns that contain the memory. However, it is unclear how the behavior is controlled by the brain so that after convergence to one configuration, it can proceed with recognition of another one. In the Hopfield model, this happens only through unrealistic changes of an effective global temperature that destabilizes all stored configurations. Here we show that spike-frequency adaptation (SFA), a common mechanism affecting neuron activation in the brain, can provide state-dependent control of pattern retrieval. We demonstrate this in a Hopfield network modified to include SFA, and also in a model network of biophysical neurons. In both cases, SFA allows for selective stabilization of attractors with different basins of attraction, and also for temporal dynamics of attractor switching that is not possible in standard autoassociative schemes. The dynamics of our models give a plausible account of different sorts of memory retrieval.

  11. Positive and negative generation effects, hypermnesia, and total recall time.

    Mulligan, Neil W; Duke, Marquinn D

    2002-10-01

    Self-generated information is typically remembered better than perceived information (the generation effect). Experimental design produces an important limiting condition for this effect: Generation enhances recall in within-subjects designs, but typically not in between-subjects designs. However, Mulligan (2001) found that the generation effect emerged over repeated recall tests in a between-subjects design, calling into question the generality of this limiting condition. Two experiments further delineated the emergent generation effect Experiment 1 demonstrated that this effect does not require multiple discrete recall tests but may emerge on a single recall test of long duration. Experiment 2 demonstrated that the negative generation effect (a reversal of the typical generation effect produced under certain conditions) is abolished by multiple recall tests. In both experiments, the generate condition produced greater hypemnesia (increased recall over tests) than did the read condition. PMID:12507369

    Iowa egg producers recalled nearly 500 million eggs in August 2010. The typical effect of a recall is to cause a decline in the demand for the affected product, yielding a decrease in the price. In the case of August 2010 egg recall, the price of eggs increased in the following weeks. This essay investigates the market effects of the egg recall. I estimate a system of simultaneous equations that includes supply and demand equations for the two main segments of the US industry. This essay offe...

A list of 20 Arabic abstract and concrete words was then given to them to be classified into abstract and concrete words based on four factor...

  16. Effect of dietary pectin on iron absorption and turnover in the rat

    The influence of dietary pectin on iron absorption and retention was studied in rats. Basal diet with low and normal iron levels were fed with and without addition of 2% citrus pectin. After 40 days rats were fasted for 24 hours and were given 59Fe in dilute HCl with or without 2% pectin by gavage. Whole-body counting techniques were employed to monitor 59Fe absorption and turnover. Rats maintained on low iron diet absorbed and retained a much higher proportion of 59Fe than rats maintained on normal level of iron. Dietary pectin at the level fed in this study had no influence on iron uptake and/or turnover in rats

  19. Parapraxes in song recall: a neglected variable.

    Díaz de Chumaceiro, C L

    1993-09-01

    In addition to expressing themselves with verbal and nonverbal communications, and by the countertransference reactions perceived by analysts, patients also reveal their inner world of images and feelings specifically with music evocations. This paper presents an initial attempt to identify and classify some of the parapraxes produced in the evocation of lyrics and music by polyglot members of treatment dyads in two empirical studies and in private practice. There may be many others, particularly related to the music per se. This paper has focused mainly on the lyrics, the equivalent of the manifest content of dreams, which nonmusician therapists can learn to handle well. Instead, in the case of the musical latent content, some knowledge of music is necessary. Supervisors' songs were considered beyond the scope of this paper and will be addressed separately. Parapraxes in song recall signal unconscious transference-countertransference states in process at the moment of evocation. PMID:8214208

    Dietary patterns represent the combined effects of foods, and illustrate efficaciously the impact of diet on health outcomes. Some findings of previous studies have limited applicability to Chinese children due to cultural factors. The present study was designed to identify dietary patterns and determine their relationships with obesity among Chinese children and adolescents. Data collected from 1282 children and adolescents aged 7-17 years from the 2011 China Health and Nutrition Survey (CHNS) were used. Dietary patterns were identified using factor analysis of data from three consecutive 24-h dietary recalls. Weight and height were measured following standard methods, and BMI was calculated. Three dietary patterns were identified: modern (high intakes of milk, fast foods and eggs), traditional north (high intakes of wheat, tubers and other cereals) and traditional south (high intakes of vegetables, rice and pork). After adjusting for some confounders and total energy intake, subjects in the highest quartiles of the modern and traditional north patterns were found to have significantly greater risk of obesity (OR 3·10, 95 % CI 1·52, 6·32, and OR 2·42, 95 % CI 1·34, 4·39, respectively). In conclusion, the modern dietary pattern and the traditional north dietary pattern were associated with higher risk of obesity. Promoting healthier eating patterns could help prevent obesity in Chinese children. PMID:25944159

  4. Some intrusions in dietary reports by fourth-grade children are based on specific memories: data from a validation study of the effect of interview modality

    Smith, Albert F.; Baxter, Suzanne Domel; Hardin, James W.; Royer, Julie A.; Guinn, Caroline H

    2008-01-01

    In dietary recall for a specified target period, an intrusion denotes an item reported eaten that was not consumed during that period. Intrusions may denote items available during the specified period, items consumed during other periods, or items from general knowledge of dietary intake. To investigate a cognitive basis of intrusions, we analyzed data from a dietary-reporting validation study in which 69 fourth-grade children were observed eating two school meals (breakfast; lunch) and inter...

  5. Food Recalls and Food Safety Perceptions: The September 2006 Spinach Recall Case

    Onyango, Benjamin M.; Miljkovic, Dragan; Hallman, William K.; Nganje, William E.; Condry, Sarah C.; Cuite, Cara L.

    2007-01-01

    This paper examines public perceptions on food safety particularly relating to spinach, which was subject of countrywide recall in 2006. Results indicate that food safety perceptions may be driven by public trust/confidence in institutions whose activities may be directly or indirectly related to food safety. The results further suggest that food safety perceptions may also be related to the type of the product; for example, the public perceives frozen spinach differently from bagged fresh sp...

  6. The accuracy of symptom recall in eating disorders.

    Peterson, Carol B; Miller, Kathryn B; Johnson-Lind, Joy; Crow, Scott J; Thuras, Paul

    2007-01-01

    The purpose of this study was to assess how accurately patients with eating disorders recall their symptoms after 6 to 12 months, to evaluate whether more recent symptoms are remembered more accurately, and to determine the extent to which the accuracy of recall impacts diagnostic classification. Seventy women who were enrolled in a longitudinal study of eating disorder symptoms were asked to recall their eating patterns, behaviors, and attitudes from 6 or 12 months earlier using semistructured interviews (Eating Disorders Examination and McKnight Longitudinal Follow-up Interview for Eating Disorders). Results indicated that correlations between the original and recalled data for frequency of objective binge eating episodes and vomiting ranged from r = .534 to .898 (average, r = .772), with lower correlations for subjective binge eating episodes (average, r = .335). Attitudes toward shape and weight were recalled more accurately at 6 months (average, r = .907) than 12 months (average, r = .620). kappa Coefficients were higher for eating disorder diagnoses using broad than narrow definitions, with no differences between 6- and 12-month recall. Overall, agreement for depression recall was low but better at 6 months (kappa = .423) than 12 months (kappa = .296). These findings suggest that patients with eating disorders are at least moderately accurate when recalling most symptoms from 6 to 12 months earlier. Although broadly defined eating disorder diagnoses remained consistent, depression and narrower eating disorder diagnostic classifications showed more variability. PMID:17145282

  20. Recall Rate in Screening Mammography, What is Optimal?

    Maryam Moradi

    2010-05-01

    Full Text Available Recall rate is defined as the percentage of screening mammography for which further work up is recommended. As the recall rate increases, sensivity is increased but specificity and positive predictive value are decreased. It is a trade off between sensivity and specificity."nIndeed in all the women recalled, a very few cancer patients were diagnosed at the expence of an increased number of procedures for a large population of the non-cancerous group and the associated cost, time and anxiety."nThe purpose of this presentation is to review the main criteria for measured performance of screening mammography, the role of recall rate as a surrogate measure and discussing the target or optimal recall rate.
